  1. Multidimensional Analyses of Long-Term Clinical Courses of Asthma and Chronic Obstructive Pulmonary Disease

    Full Text Available ABSTRACT: Asthma and chronic obstructive pulmonary disease (COPD are chronic respiratory disorders involving obstructive airway defects. There have been many discussions on their similarities and differences. Although airflow limitation expressed as forced expiratory volume in one second (FEV1 has been considered to be the main diagnostic assessment in both diseases, it does not reflect the functional impairment imparted to the patients by these diseases. Therefore, multidimensional approaches using multiple measurements in assessing disease control or severity have been recommended, and multiple endpoints in addition to FEV1 have been set recently in clinical trials so as not to miss the overall effects. In particular, as improving symptoms and health status as well as pulmonary function are important goals in the management of asthma and COPD, some patient-reported measurements such as health-related quality of life or dyspnea should be included. Nonetheless, there have been few reviews on the long-term clinical course comparing asthma and COPD as predicted by measurements other than airflow limitation. Here, we therefore analyzed and compared longitudinal changes in both physiological measurements and patient-reported measurements in asthma and COPD. Although both diseases showed similar long-term progressive airflow limitation similarly despite guideline-based therapies, disease progression was different in asthma and COPD. In asthma, patient-reported assessments of health status, disability and psychological status remained clinically stable over time, in contrast to the significant deterioration of these parameters in COPD. Thus, because a single measurement of airflow limitation is insufficient to monitor these diseases, multidimensional analyses are important not only for disease control but also for understanding disease progression in asthma and COPD.

    Pruritus or itch is a frequent symptom of patients with Hodgkin's disease. It often occurs during the clinical course of the disease and rarely may precede the diagnosis of underlying disease. In this report, we present a 16-year-old patient who had history of generalized pruritus without any skin rash for 4 years before the diagnosis of Hodgkin's disease. Within that period, she had received symptom-oriented medications, with no significant effect. After the first cycle of chemotherapy, her pruritus resolved completely. This case suggests that long-term generalized pruritus may be indicative of a significant underlying problem like Hodgkin's disease.

    Rasagiline (N-propargyl-1 (R)-aminoindan) is a selective, potent irreversible inhibitor of MAO-B that possesses neuroprotective and anti-apoptotic properties in a variety of in vitro and in vivo animal models relevant to Parkinson's disease (PD). Several randomized controlled clinical trials have demonstrated the safety and efficacy of rasagiline as monotherapy in PD and as adjunctive therapy for patients receiving levodopa. In addition, the 1-year randomized, delayed-start analysis of the TEMPO study suggests that rasagiline may slow the rate of progression of PD. The randomized delayed-start paradigm has potential to differentiate short-term symptomatic effects from long-term effects of anti-parkinsonian agents. In the future, long-term trials to examine the potential disease-modifying effects of rasagiline, which incorporate biological markers as well as clinical endpoints, may further elucidate the role of rasagiline in the treatment of both early and advanced PD.

    Enzyme replacement therapy (ERT) has deeply modified the clinical history of Infantile Onset Pompe Disease (IOPD). However, its long-term effectiveness is still not completely defined. Available data shows a close relationship between clinical outcome and patients' cross-reactive immunological status (CRIM), being CRIM-negative status a negative prognostic factor. At the same time limited data are available on the long-term treatment in CRIM-positive infants. A retrospective multicentre observational study was designed to analyse the long-term effectiveness of ERT in IOPD. Thirteen Italian centres spread throughout the country were involved and a cohort of 28 patients (15 females, 13 males, born in the period: February 2002-January 2013) was enrolled. IOPD diagnosis was based on clinical symptoms, enzymatic and molecular analysis. All patients received ERT within the first year of life. Clinical, laboratory, and functional data (motor, cardiac and respiratory) were collected and followed for a median period of 71 months (5 years 11 months). Median age at onset, diagnosis and start of ERT were 2, 3 and 4 months, respectively. CRIM status was available for 24/28 patients: 17/24 (71%) were CRIM-positive. Nineteen patients (67%) survived > 2 years: 4 were CRIM-negative, 14 CRIM-positive and one unknown. Six patients (5 CRIM-positive and one unknown) never needed ventilation support (21,4%) and seven (6 CRIM-positive and one unknown: 25%) developed independent ambulation although one subsequently lost this function. Brain imaging study was performed in 6 patients and showed peri-ventricular white matter abnormalities in all of them. Clinical follow-up confirmed the better prognosis for CRIM-positive patients, though a slow, progressive worsening of motor and/or respiratory functions was detected in 8 patients. These data are the result of the longest independent retrospective study on ERT in IOPD reported so far outside clinical trials. The data obtained

    The American Association of Clinical Endocrinologists (AACE) and American College of Endocrinology (ACE) have created a chronic care model, advanced diagnostic framework, clinical practice guidelines, and clinical practice algorithm for the comprehensive management of obesity. This coordinated effort is not solely based on body mass index as in previous models, but emphasizes a complications-centric approach that primarily determines therapeutic decisions and desired outcomes. Adiposity-Based Chronic Disease (ABCD) is a new diagnostic term for obesity that explicitly identifies a chronic disease, alludes to a precise pathophysiologic basis, and avoids the stigmata and confusion related to the differential use and multiple meanings of the term "obesity." Key elements to further the care of patients using this new ABCD term are: (1) positioning lifestyle medicine in the promotion of overall health, not only as the first algorithmic step, but as the central, pervasive action; (2) standardizing protocols that comprehensively and durably address weight loss and management of adiposity-based complications; (3) approaching patient care through contextualization (e.g., primordial prevention to decrease obesogenic environmental risk factors and transculturalization to adapt evidence-based recommendations for different ethnicities, cultures, and socio-economics); and lastly, (4) developing evidence-based strategies for successful implementation, monitoring, and optimization of patient care over time. This AACE/ACE blueprint extends current work and aspires to meaningfully improve both individual and population health by presenting a new ABCD term for medical diagnostic purposes, use in a complications-centric management and staging strategy, and precise reference to the obesity chronic disease state, divested from counterproductive stigmata and ambiguities found in the general public sphere.

To evaluate the long-term efficacy and safety of galantamine for AD in routine clinical practice, we conducted a 72-week post-marketing surveillance study. The effect of galantamine on cognitive function was estimated in comparison with a simulated disease trajectory. Patients and methods: Patients with mild-to-moderate AD received flexible dosing of galantamine (16–24 mg/day during this study. Cognitive function was assessed by the mini mental state examination (MMSE and the clinical status was determined by the Clinical Global Impression-Improvement (CGI-I. Changes of the MMSE score without treatment were estimated in each patient using Mendiondo’s model. Generalized linear mixed model analysis was performed to compare the simulated MMSE scores with the actual scores. Results: Of the 661 patients who were enrolled, 642 were evaluable for safety and 554 were assessed for efficacy. The discontinuation rate was 46.73%. Cognitive decline indicated by the mean change of actual MMSE scores was significantly smaller than the simulated decline. Individual analysis demonstrated that >70% of patients had better actual MMSE scores than their simulated scores. Significant improvement of CGI-I was also observed during the observation period. Adverse events occurred in 28.5% of patients and were serious in 8.41%. The reported events generally corresponded with the

    Bronchopulmonary dysplasia (BPD) is a serious neonatal pulmonary condition associated with premature birth, but the underlying parenchymal disease and trajectory are poorly characterized. The current NICHD/NHLBI definition of BPD severity is based on degree of prematurity and extent of oxygen requirement. However, no clear link exists between initial diagnosis and clinical outcomes. We hypothesized that magnetic resonance imaging (MRI) of structural parenchymal abnormalities will correlate with NICHD-defined BPD disease severity and predict short-term respiratory outcomes. Forty-two neonates (20 severe BPD, 6 moderate, 7 mild, 9 non-BPD controls; 40±3 weeks post-menstrual age) underwent quiet-breathing structural pulmonary MRI (ultrashort echo-time and gradient echo) in a NICU-sited, neonatal-sized 1.5T scanner, without sedation or respiratory support unless already clinically prescribed. Disease severity was scored independently by two radiologists. Mean scores were compared to clinical severity and short-term respiratory outcomes. Outcomes were predicted using univariate and multivariable models including clinical data and scores. MRI scores significantly correlated with severities and predicted respiratory support at NICU discharge (P<0.0001). In multivariable models, MRI scores were by far the strongest predictor of respiratory support duration over clinical data, including birth weight and gestational age. Notably, NICHD severity level was not predictive of discharge support. Quiet-breathing neonatal pulmonary MRI can independently assess structural abnormalities of BPD, describe disease severity, and predict short-term outcomes more accurately than any individual standard clinical measure. Importantly, this non-ionizing technique can be implemented to phenotype disease and has potential to serially assess efficacy of individualized therapies.

    The long-term outcome of percutaneous coronary intervention (PCI) vs. coronary artery bypass graft (CABG), particularly for patients with non-ST-elevation acute coronary syndrome (NSTE-ACS), remains controversial.Methods and Results:We retrospectively analyzed 2,827 patients (stable coronary artery disease [SCAD], n=1,601; NSTE-ACS, n=1,226) who underwent either PCI (n=1,732) or CABG (n=1,095). The 8-year composite of cardiac death and myocardial infarction (MI) was compared between PCI and CABG before and after propensity matching. For patients with NSTE-ACS, PCI was performed more frequently for those with higher Thrombolysis in Myocardial Infarction risk score and 3-vessel disease, and PCI led to significantly higher 8-year composite of cardiac death and MI than CABG (14.1% vs. 5.9%, hazard ratio [HR]=2.22, 95% confidence interval [CI]=1.37-3.58, P=0.001). There was a significant interaction between clinical presentation and revascularization strategy (P-interaction=0.001). However, after matching, the benefit of CABG vs. PCI was attenuated in patients with NSTE-ACS, whereas it was pronounced in those with SCAD. Interactions between clinical presentation and revascularization strategy were not observed (P-interaction=0.574). Although the determinants of PCI vs. CABG in real-world clinical practice differ according to the clinical presentation, a significant interaction between clinical presentation and revascularization strategy was not noted for long-term outcomes. The revascularization strategy for patients with NSTE-ACS can be based on the criteria applied to patients with SCAD.

    To review available medical therapies for patients with Cushing disease and to provide a roadmap for their use in clinical practice. PubMed searches were performed to identify all of the available published data on medical management of Cushing disease. Medical therapy is usually not the first-line treatment for patients with Cushing disease but may be used to improve clinical manifestations of Cushing disease in patients who are not suitable candidates for surgery, following unsuccessful surgery or recurrence, or as a "bridge therapy" in those who have undergone radiotherapy. Medical therapy may also be used in preoperative preparation of patients with severe disease. Current available medical options for patients with Cushing disease include centrally acting agents, steroidogenesis inhibitors, and a glucocorticoid receptor antagonists. At present, there are no head-to-head studies comparing the efficacy, tolerability, and safety of different U.S. Food and Drug Administration (FDA)- and non-FDA-approved drugs in patients with Cushing disease. With the initiation of new studies and the completion of ongoing clinical trials, the number of FDA-approved drugs for medical treatment of Cushing disease is expected to increase. Medical therapy has an important adjunctive role in the management of patients with Cushing disease. The decision to initiate medical treatment depends on many factors, including patient characteristics and preference. Long-term studies are needed to better define the clinical efficacy, safety, and tolerability of medical treatment of Cushing disease, including the role of combination therapies.

    Background Published clinical problem solving exercises have emerged as a common tool to illustrate aspects of the clinical reasoning process. The specific clinical reasoning terms mentioned in such exercises is unknown. Objective We identified which clinical reasoning terms are mentioned in published clinical problem solving exercises and compared them to clinical reasoning terms given high priority by clinician educators. Methods A convenience sample of clinician educators prioritized a list of clinical reasoning terms (whether to include, weight percentage of top 20 terms). The authors then electronically searched the terms in the text of published reports of 4 internal medicine journals between January 2010 and May 2013. Results The top 5 clinical reasoning terms ranked by educators were dual-process thinking (weight percentage = 24%), problem representation (12%), illness scripts (9%), hypothesis generation (7%), and problem categorization (7%). The top clinical reasoning terms mentioned in the text of 79 published reports were context specificity (n = 20, 25%), bias (n = 13, 17%), dual-process thinking (n = 11, 14%), illness scripts (n = 11, 14%), and problem representation (n = 10, 13%). Context specificity and bias were not ranked highly by educators. Conclusions Some core concepts of modern clinical reasoning theory ranked highly by educators are mentioned explicitly in published clinical problem solving exercises. However, some highly ranked terms were not used, and some terms used were not ranked by the clinician educators. Effort to teach clinical reasoning to trainees may benefit from a common nomenclature of clinical reasoning terms.

    Potential targets for treat-to-target strategies in JIA are minimal disease activity (MDA) and clinically inactive disease (CID). Short and long-term outcomes following achievement of MDA and CID on the cJADAS10 and CID on Wallace's preliminary criteria were compared. Children recruited to the Childhood Arthritis Prospective Study, a UK multicentre inception cohort, were selected if recruited prior to January 2011 and diagnosed with oligoarthritis or rheumatoid factor negative or positive polyarthritis. At one year following diagnosis, children were assessed for MDA on the cJADAS10 and CID on both Wallace's preliminary criteria and the cJADAS10. Associations were tested between these disease states and i) functional ability, ii) absence of limited joints, iii) psychosocial health and v) pain at one year and annually to five years. Of 832 children, 70% were female and the majority had oligoarthritis (68%). At one year, 21% had achieved CID according to both definitions, 7% on Wallace's preliminary criteria only, 16% on cJADAS10 only and 56% on neither. Only 10% of children in the entire cohort achieved MDA without also having CID. Achieving either early CID state was associated with greater absence of limited joints. However, only CID on cJADAS10 was associated with improved functional ability and psychosocial health. Achieving CID was superior to MDA in terms of short and long-term pain and the absence of limited joints. CID on the cJADAS10 may be a preferable treatment target to CID on Wallace's preliminary criteria in terms of both feasibility of application and long-term outcomes.

    Although congestive heart failure (CHF) is a primary target for disease management programs, previous studies have generated mixed results regarding the effectiveness and cost savings of disease management when applied to CHF. We estimated the long-term impact of systolic heart failure disease management from the results of an 18-month clinical trial. We used data generated from the trial (starting population distributions, resource utilization, mortality rates, and transition probabilities) in a Markov model to project results of continuing the disease management program for the patients' lifetimes. Outputs included distribution of illness severity, mortality, resource consumption, and the cost of resources consumed. Both cost and effectiveness were discounted at a rate of 3% per year. Cost-effectiveness was computed as cost per quality-adjusted life year (QALY) gained. Model results were validated against trial data and indicated that, over their lifetimes, patients experienced a lifespan extension of 51 days. Combined discounted lifetime program and medical costs were $4850 higher in the disease management group than the control group, but the program had a favorable long-term discounted cost-effectiveness of $43,650/QALY. These results are robust to assumptions regarding mortality rates, the impact of aging on the cost of care, the discount rate, utility values, and the targeted population. Estimation of the clinical benefits and financial burden of disease management can be enhanced by model-based analyses to project costs and effectiveness. Our results suggest that disease management of heart failure patients can be cost-effective over the long term.

    Persistent airway inflammation with mucus retention in patients with chronic airway disorders such as COPD and bronchiectasis may lead to frequent exacerbations, reduced lung function and poor quality of life. This study investigates if long-term humidification therapy with high flow fully humidified air at 37 degrees C through nasal cannulae can improve these clinical outcomes in this group of patients. 108 patients diagnosed with COPD or bronchiectasis were randomised to daily humidification therapy or usual care for 12 months over which exacerbations were recorded. Lung function, quality of life, exercise capacity, and measures of airway inflammation were also recorded at baseline, 3 and 12 months. Patients on long-term humidification therapy had significantly fewer exacerbation days (18.2 versus 33.5 days; p = 0.045), increased time to first exacerbation (median 52 versus 27 days; p = 0.0495) and reduced exacerbation frequency (2.97/patient/year versus 3.63/patient/year; p = 0.067) compared with usual care. Quality of life scores and lung function improved significantly with humidification therapy compared with usual care at 3 and 12 months. Long-term humidification therapy significantly reduced exacerbation days, increased time to first exacerbation, improved lung function and quality of life in patients with COPD and bronchiectasis.

    There is no consensus on the remission criteria for Cushing's disease or on the definition of disease recurrence after transsphenoidal surgery, and comparison of the different published series is therefore difficult. A long-term recurrence rate of Cushing's disease ranging from 2%-25% has been reported. Predictors of long-term remission reported include: 1) adenoma-related factors (aggressiveness, size, preoperative identification in MRI), 2) surgery-related factors, mainly neurosurgeon experience, 3) clinical factors, of which dependence on and duration of glucocorticoid treatment are most important, and 4) biochemical factors. Among the latter, low postoperative cortisol levels, less than 2 mcg/dL predict for disease remission. However, even when undetectable plasma cortisol levels are present, long-term recurrence may still occur and lifetime follow-up is required. We report the preliminary results of the first 20 patients with Cushing's disease operated on at our hospital using nadir cortisol levels less than 2 mcg/dl as remission criterion.

    Full Text Available Presented clinical cases of patients with a diagnosis of gluten enteropathy in treatment in the department of gastroenterology Regional Clinical Hospital. The case is of interest to doctors of different specialties for the differential diagnosis of anemia and malabsorption syndrome, demonstrate both the classic version, and atypical forms of the disease course. Diagnosis of celiac disease is based on three key positions: clinical findings, histology and serological markers. The clinical picture of celiac disease is characterized by pronounced polymorphism, by going beyond the a gastroenterological pathology. For screening of gluten sensitive celiac typically used an antibody to tissue transglutaminase. Morphological research of the mucous membrane of the small intestine is the determining criterion in the diagnosis of celiac disease. The use of specific gluten-free diet leads to the positive dynamics of the disease and improve the quality of life of patients.

    BACKGROUND: The encephalopathy associated with autoimmune thyroid disease (EAATD) is characterized by neurological\\/psychiatric symptoms, high levels of anti-thyroid antibodies, increased cerebrospinal fluid protein concentration, non-specific electroencephalogram abnormalities, and responsiveness to the corticosteroid treatment in patients with an autoimmune thyroid disease. Almost all EAATD patients are affected by Hashimoto\\'s thyroiditis (HT), although fourteen EAATD patients with Graves\\' disease (GD) have been also reported. METHODS: We have recorded and analyzed the clinical, biological, radiological, and electrophysiological findings and the data on the therapeutic management of all GD patients with EAATD reported so far as well as the clinical outcomes in those followed-up in the long term. RESULTS: Twelve of the fourteen patients with EAATD and GD were women. The majority of GD patients with EAATD presented with mild hyperthyroidism at EAATD onset or shortly before it. Active anti-thyroid autoimmunity was detected in all cases. Most of the patients dramatically responded to corticosteroids. The long term clinical outcome was benign but EAATD can relapse, especially at the time of corticosteroid dose tapering or withdrawal. GD and HT patients with EAATD present with a similar clinical, biological, radiological, and electrophysiological picture and require an unaffected EAATD management. CONCLUSIONS: GD and HT equally represent the possible background condition for the development of EAATD, which should be considered in the differential diagnosis of all patients with encephalopathy of unknown origin and an autoimmune thyroid disease, regardless of the nature of the underlying autoimmune thyroid disease.

The data of grip strength, pain (visual analog scale (VAS score, wrist range of motion (ROM, ulnar variance (according to Palmer method, and the Lichtman stage were gathered before and after surgery. We evaluated overall wrist function using the Mayo Wrist score and disabilities of the arm shoulder and hand (DASH score before surgery and at the last follow-up. Results: The average of follow-up was 7 years (range from 5 to 9 years. Preoperative ulnar variance was -1.3 mm (range from 2.5 to 1 preoperatively. The mean postoperative ulnar variance was 1 mm positive (range from 0.5 to 1.5. The VAS pain score, the mean arc of wrist flexion and extension, and grip strength improved significantly preoperatively compared to after recovery from surgery. The Lichtman stage was unchanged in nine patients, one grade worse in six patients, and one grade better in one patient. The mean DASH and Mayo scores improved significantly postoperatively compare with preoperation. Comparing preoperative positive, neuter, and negative ulnar variance, there was no significant difference in terms of VAS, DASH, and Mayo scores as well as ROM and grip strength. Conclusion: Our study shows that radius shortening surgery improves pain and disability regardless of ulnar variance.

    Full Text Available Abstract Background The encephalopathy associated with autoimmune thyroid disease (EAATD is characterized by neurological/psychiatric symptoms, high levels of anti-thyroid antibodies, increased cerebrospinal fluid protein concentration, non-specific electroencephalogram abnormalities, and responsiveness to the corticosteroid treatment in patients with an autoimmune thyroid disease. Almost all EAATD patients are affected by Hashimoto's thyroiditis (HT, although fourteen EAATD patients with Graves' disease (GD have been also reported. Methods We have recorded and analyzed the clinical, biological, radiological, and electrophysiological findings and the data on the therapeutic management of all GD patients with EAATD reported so far as well as the clinical outcomes in those followed-up in the long term. Results Twelve of the fourteen patients with EAATD and GD were women. The majority of GD patients with EAATD presented with mild hyperthyroidism at EAATD onset or shortly before it. Active anti-thyroid autoimmunity was detected in all cases. Most of the patients dramatically responded to corticosteroids. The long term clinical outcome was benign but EAATD can relapse, especially at the time of corticosteroid dose tapering or withdrawal. GD and HT patients with EAATD present with a similar clinical, biological, radiological, and electrophysiological picture and require an unaffected EAATD management. Conclusions GD and HT equally represent the possible background condition for the development of EAATD, which should be considered in the differential diagnosis of all patients with encephalopathy of unknown origin and an autoimmune thyroid disease, regardless of the nature of the underlying autoimmune thyroid disease.

    Similarity-based retrieval of Electronic Health Records (EHRs) from large clinical information systems provides physicians the evidence support in making diagnoses or referring examinations for the suspected cases. Clinical Terms in EHRs represent high-level conceptual information and the similarity measure established based on these terms reflects the chance of inter-patient disease co-occurrence. The assumption that clinical terms are equally relevant to a disease is unrealistic, reducing the prediction accuracy. Here we propose a term weighting approach supported by PubMed search engine to address this issue. We collected and studied 112 abdominal computed tomography imaging examination reports from four hospitals in Hong Kong. Clinical terms, which are the image findings related to hepatocellular carcinoma (HCC), were extracted from the reports. Through two systematic PubMed search methods, the generic and specific term weightings were established by estimating the conditional probabilities of clinical terms given HCC. Each report was characterized by an ontological feature vector and there were totally 6216 vector pairs. We optimized the modified direction cosine (mDC) with respect to a regularization constant embedded into the feature vector. Equal, generic and specific term weighting approaches were applied to measure the similarity of each pair and their performances for predicting inter-patient co-occurrence of HCC diagnoses were compared by using Receiver Operating Characteristics (ROC) analysis. The Areas under the curves (AUROCs) of similarity scores based on equal, generic and specific term weighting approaches were 0.735, 0.728 and 0.743 respectively (p PubMed. Our findings suggest that the optimized similarity measure with specific term weighting to EHRs can improve significantly the accuracy for predicting the inter-patient co-occurrence of diagnosis when compared with equal and generic term weighting approaches.

    Full Text Available CONTEXT: In Machado-Joseph disease, poor posture, dystonia and peripheral neuropathy are extremely predisposing to oropharyngeal dysphagia, which is more commonly associated with muscular dystrophy. OBJECTIVE: To evaluate the clinical characteristics of oropharyngeal dysphagia in Machado-Joseph disease patients. METHOD: Forty individuals participated in this study, including 20 with no clinical complaints and 20 dysphagic patients with Machado-Joseph disease of clinical type 1, who were all similar in terms of gender distribution, average age, and cognitive function. The medical history of each patient was reviewed and each subject underwent a clinical evaluation of deglutition. At the end, the profile of dysphagia in patients with Machado-Joseph disease was classified according to the Severity Scale of Dysphagia, as described by O'Neil and collaborators. RESULTS: Comparison between dysphagic patients and controls did not reveal many significant differences with respect to the clinical evaluation of the oral phase of deglutition, since afflicted patients only demonstrated deficits related to the protrusion, retraction and tonus of the tongue. However, several significant differences were observed with respect to the pharyngeal phase. Dysphagic patients presented pharyngeal stasis during deglutition of liquids and solids, accompanied by coughing and/or choking as well as penetration and/or aspiration; these signs were absent in the controls. CONCLUSIONS: Oropharyngeal dysphagia is part of the Machado-Joseph disease since the first neurological manifestations. There is greater involvement of the pharyngeal phase, in relation to oral phase of the deglutition. The dysphagia of these patients is classified between mild and moderate.

    With antimicrobial resistance increasing worldwide, there is a great need to use automated antimicrobial decision support systems (ADSSs) to lower antimicrobial resistance rates by promoting appropriate antimicrobial use. However, they are infrequently used mostly because of their poor interoperability with different health information technologies. Ontologies can augment portable ADSSs by providing an explicit knowledge representation for biomedical entities and their relationships, helping to standardize and integrate heterogeneous data resources. We developed a bacterial clinical infectious diseases ontology (BCIDO) using Protégé-OWL. BCIDO defines a controlled terminology for clinical infectious diseases along with domain knowledge commonly used in hospital settings for clinical infectious disease treatment decision-making. BCIDO has 599 classes and 2355 object properties. Terms were imported from or mapped to Systematized Nomenclature of Medicine, Unified Medical Language System, RxNorm and National Center for Bitechnology Information Organismal Classification where possible. Domain expert evaluation using the “laddering” technique, ontology visualization, and clinical notes and scenarios, confirmed the correctness and potential usefulness of BCIDO. PMID:24551353

    Full Text Available and lsquo;Pilonidal sinus' disease, which is most commonly seen in reproductive populations, such as young adults - mostly in males who are in their twenties - is actually a controversial disease in that there is no consensus on its many facets. It is sometimes seen as an infected abscess draining from an opening or a lesion extending to the perineum. It may also present as a draining fistula opening to skin. In terms of etiological factors, various theories (main theories being congenital and acquired have been established since it was first described, no universal understanding achieved. A long and significant post-operative care period with different lengths of recovery depending on the type of operation are quite prevalent with regards to recurrence and complication status. In order to prevent recurrence and improve the quality of life, etiological and predisposing factors as well as clinical features of sacrococcygeal pilonidal disease should be well known, a detailed differential diagnosis should be made, and a suitable and timely intervention should be performed. It was aimed here to explain the etiological factors, pathogenesis and clinical features of the disease that may present with various clinical symptoms. [Arch Clin Exp Surg 2016; 5(4.000: 228-232

    Creutzfeldt-Jakob disease accounts for more than 90% of all sporadic prion disease cases. The molecular MM2 genotype has been divided into cortical and thalamic subtypes based on structures involved and is characterized clinically by progressive dementia without ataxia or typical electroencephalography changes. Proposed diagnostic criteria for MM2 cortical type sporadic Creutzfeldt-Jakob disease include progressive dementia, cortical hyper-intensity on diffusion-weighted magnetic resonance imaging, increased cerebrospinal fluid 14-3-3 protein level, and the exclusion of other types of dementia. The presence of periodic discharges on electroencephalography in MM2 cortical type were reported in 42% of the cases. We are reporting a case of sporadic Creutzfeldt-Jakob disease cortical MM2-type presenting with rapid cognitive decline, who survived 8 months since symptom onset. Brain imaging, cerebrospinal fluid analysis, and long-term electroencephalography monitoring were obtained and diagnosis was confirmed by autopsy. Short-term electroencephalography recording, performed 5 months after symptom onset, demonstrated diffuse background slowing without epileptiform activity. Long-term video electroencephalography monitoring demonstrated generalized slowing, maximum in bilateral frontal areas, which intermittently would become rhythmic (1-2 Hz) without hemispheric predominance. If the findings do not clearly meet the proposed clinical criteria for sporadic Creutzfeldt-Jakob disease, the use of long-term electroencephalography could increase the sensitivity. We question whether the lack of the characteristic findings on electroencephalography in some cases could be due to insufficient time of recording. Application of long-term electroencephalography monitoring increases the sensitivity of electroencephalography and the certainty of pre-mortem diagnosis of sporadic Creutzfeldt-Jakob disease.

    Full Text Available OBJECTIVE: To describe the clinical presentation a group of patients with juvenile onset of Huntington disease. METHOD: All patients were interviewed following a structured clinical questioner. Patients were genotyped for the trinucleotide cytosine-adenine-guanine (CAG repeat in the Huntington Disease gene. High resolution brain MRI was performed in all patients. RESULTS: We identified 4 patients with juvenile onset of disease among 50 patients with Huntington disease followed prospectively in our Neurogenetics clinic. Age at onset varied from 3 to 13 years, there were 2 boys, and 3 patients had a paternal inheritance of the disease. Expanded Huntington disease allele sizes varied from 41 to 69 trinucleotide repeats. The early onset patients presented with rigidity, bradykinesia, dystonia, dysarthria, seizures and ataxia. MRI showed severe volume loss of caudate and putamen nuclei (p=0.001 and reduced cerebral and cerebellum volumes (p=0.01. CONCLUSION: 8% of Huntington disease patients seen in our clinic had juvenile onset of the disease. They did not present with typical chorea as seen in adult onset Huntington disease. There was a predominance of rigidity and bradykinesia. Two other important clinical features were seizures and ataxia, which related with the imaging findings of early cortical atrophy and cerebellum volume loss.

    Full Text Available Paricalcitol is approved for prevention and therapy of secondary hyperparathyroidism (sHPT in patients with chronic kidney disease (CKD, with only short-term data in clinical routine settings. A 12-month observational study was conducted in Germany and Austria (90 centers, 761 patients from 2008 to 2013. Laboratory values, demographical, and clinical data were documented in 629 dialysis patients and 119 predialysis patients. In predialysis patients, median intact parathormone (iPTH was 180.0 pg/mL (n = 105 at the start of the study, 115.7 pg/mL (n = 105 at last documentation, and 151.8 pg/mL (n = 50 at month 12, with 32.4% of the last documented iPTH values in the KDOQI (Kidney Disease Outcomes Quality Initiative target range. In dialysis patients, median iPTH was 425.5 pg/mL (n = 569 at study start, 262.3 pg/mL (n = 569 at last documentation, and 266.1 pg/mL (n = 318 at month 12, with 36.5% of dialysis patients in the KDOQI target range. Intravenous paricalcitol showed more homogenous iPTH control than oral treatment. Combined analysis of all dialysis patients indicated comparable and stable mean serum calcium and phosphate levels throughout the study. Clinical symptoms, such as itching, bone pain, and fatigue, were improved compared with study entry. The spectrum and frequency of adverse events mirrored the known pattern for patients on dialysis. Paricalcitol is efficacious and has a consistent safety profile in sHPT over 12 months.

    Full Text Available Fabry disease is an X-linked, lysosomal storage disease (OMIM: 301500, caused by α-galactosidase A deficiency, resulting in accumulation of its substrates, glycosphingolipids, primarily – globotriaosylceramide, in the lysosomes of multiple cell types with multi-system clinical manifestations, even within the same family, including abnormalities of the central and peripheral nervous system, kidneys, heart, gastrointestinal tract, lungs, organ of vision. Clinical heterogeneity is often the reason of the delayed diagnosis. Nowadays enzyme replacement therapy has proved its efficiency in the treatment of Fabry disease. Including Fabry disease in the differential diagnosis of a large range of disorders is important because of its wide clinical heterogeneity and the possibility of an earlier intervention with a beneficial treatment.

    Full Text Available Rare disease patients too often face common problems, including the lack of access to correct diagnosis, lack of quality information on the disease, lack of scientific knowledge of the disease, inequities and difficulties in access to treatment and care. These things could be changed by implementing a comprehensive approach to rare diseases, increasing international cooperation in scientific research, by gaining and sharing scientific knowledge about and by developing tools for extracting and sharing knowledge. A significant aspect to analyze is the organization of knowledge in the biomedical field for the proper management and recovery of health information. For these purposes, the sources needed have been acquired from the Office of Rare Diseases Research, the National Organization of Rare Disorders and Orphanet, organizations that provide information to patients and physicians and facilitate the exchange of information among different actors involved in this field. The present paper shows the representation of rare diseases terms in biomedical terminologies such as MeSH, ICD-10, SNOMED CT and OMIM, leveraging the fact that these terminologies are integrated in the UMLS. At the first level, it was analyzed the overlap among sources and at a second level, the presence of rare diseases terms in target sources included in UMLS, working at the term and concept level. We found that MeSH has the best representation of rare diseases terms.

    To investigate the aetiology and long-term clinical outcomes of patients diagnosed with digital ischemia. Data of 36 consecutive patients presenting with digital ischemia were collected in July 2000 to June 2001 from a vascular referral centre. Demographic data, aetiology, medication and treatment were abstracted from the medical records. Clinical outcomes were assessed at 5 year follow-up including ulcer healing, digital amputation and mortality. Of the 36 patients, 69.4% were male and the mean age was 55±14 years. In 15 patients (41.7%) a systemic disease was present and of those 53.3% was due to connective tissue disease. Twelve patients (33.3%) had hypothenar hammer syndrome and in 8 patients (22.2%) no apparent cause was found. Whereas 13 patients (36.1%) presented with rest pain or trophic lesions at baseline, no patients presented with these symptoms at follow-up. At follow-up, 18 (62.1%) patients had symptoms on provocation and 5 patients (4 patients with systemic disease and 1 with no apparent cause) had died. Digital amputation was performed in one patient at initial presentation and no digital amputation was performed at follow-up. No ulcer reoccurred and no workers' insurance compensation was applied. Of those with hypothenar hammer syndrome, 80.0% had symptoms on provocation at follow-up. Among patients with digital ischemia, systemic disease and hypothenar hammer syndrome were the most frequent aetiologies. In patients with hypothenar hammer syndrome the clinical outcome was remarkably benign, although symptoms may persist with provocation, whereas patients with systemic disease have a high mortality rate.

    Full Text Available Background: Gastroesophageal reflux disease (GERD is one of the most common problems in neonates. The main clinical manifestations of neonatal GERD are frequent regurgitation or vomiting associated with irritability, crying, anorexia or feeding refusal, failure to thrive, arching of the back and sleep disturbance.Aims: As no study has compared metoclopramide plus ranitidine with metoclopramide plus omeprazole in the management of neonatal GERD resistant to conservative and monotherapy, this study was carried out.Study design: This study was a randomized clinical trial of term neonates with GERD resistant to conservative and monotherapy admitted to the neonatal ward of Bahrami Children Hospital during 2013-2015. Totally, 116 term neonates (mean age 10.53 ± 8.17 days; girls 50.9% were randomly assigned to a double blind trial with either oral omeprazole plus metoclopramide (group A or oral ranitidine plus metoclopramide (group B. The changes of the symptoms and signs were recorded after one week and one month.Results: There was no significant difference in demographic and baseline characteristics between the two groups. The response rate of “omeprazole plus metoclopramide” was significantly higher than “ranitidine plus metoclopramide” (93.74% ± 7.28% vs. 75.43% ± 23.24%, p = 0.028. All clinical manifestations recovered significantly in group A while the response rate of irritability and wheezing was not significant in group B (primary outcome. There were no side effects in either group after one week and one month of treatment (secondary outcome.Conclusions: The response rate was > 70% in each group, but it was significantly higher in group A (> 90%. Combination of each acid suppressant with metoclopramide led to higher response rate in comparison with monotherapy used before intervention.

    We describe a girl with Cushing disease for whom surgery and radiation treatments failed and the subsequent clinical course with mifepristone therapy. We present the patient's clinical, biochemical, and imaging findings. A 16-year-old girl presented with classic Cushing disease. After transsphenoidal surgery, Cyberknife radiosurgery, ketoconazole, and metyrapone did not control her disease, and she was prescribed mifepristone, which was titrated to a maximal dosage of 1200 mg daily with subsequent symptom improvement. Mifepristone (RU486) is a high-affinity, nonselective antagonist of the glucocorticoid receptor. There is limited literature on its use as an off-label medication to treat refractory Cushing disease. Over her 8-year treatment with mifepristone, her therapy was complicated by hypertension and hypokalemia requiring spironolactone and potassium chloride. She received a 2-month drug holiday every 4 to 6 months to allow for withdrawal menstrual bleeding with medroxyprogesterone acetate. Urinary cortisol, serum cortisol, and corticotropin levels remained elevated during mifepristone drug holidays. While on mifepristone, her signs and symptoms of Cushing disease resolved. Repeated magnetic resonance imaging demonstrated stable appearance of the residual pituitary mass. Bilateral adrenalectomy was performed, and mifepristone was discontinued after 95 months of medical therapy. We describe the longest duration of mifepristone therapy thus reported for the treatment of refractory Cushing disease. Mifepristone effectively controlled all signs and symptoms of hypercortisolism. Menstruating women who take the drug on a long-term basis should receive periodic drug holidays to allow for menses. The lack of reliable serum biomarkers to monitor the success of mifepristone therapy requires careful clinical judgment and may make its use difficult in Cushing disease.

    Experience suggests that many celiac patients suffer from persistent symptoms despite a long-term gluten-free diet (GFD). We investigated the prevalence and severity of these symptoms in patients with variable duration of GFD. Altogether, 856 patients were classified into untreated (n = 128), short-term GFD (1-2 years, n = 93) and long-term GFD (≥3 years, n = 635) groups. Analyses were made of clinical and histological data and dietary adherence. Symptoms were evaluated by the validated GSRS questionnaire. One-hundred-sixty healthy subjects comprised the control group. Further, the severity of symptoms was compared with that in peptic ulcer, reflux disease, inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). Altogether, 93% of the short-term and 94% of the long-term treated patients had a strict GFD and recovered mucosa. Untreated patients had more diarrhea, indigestion and abdominal pain than those on GFD and controls. There were no differences in symptoms between the short- and long-term GFD groups, but both yielded poorer GSRS total score than controls (p = 0.03 and p = 0.05, respectively). Furthermore, patients treated 1-2 years had more diarrhea (p = 0.03) and those treated >10 years more reflux (p = 0.04) than controls. Long-term treated celiac patients showed relatively mild symptoms compared with other gastrointestinal diseases. Based on our results, good response to GFD sustained in long-term follow-up, but not all patients reach the level of healthy individuals.

  20. Integrating Transgenic Vector Manipulation with Clinical Interventions to Manage Vector-Borne Diseases.

    2016-03-01

    Full Text Available Many vector-borne diseases lack effective vaccines and medications, and the limitations of traditional vector control have inspired novel approaches based on using genetic engineering to manipulate vector populations and thereby reduce transmission. Yet both the short- and long-term epidemiological effects of these transgenic strategies are highly uncertain. If neither vaccines, medications, nor transgenic strategies can by themselves suffice for managing vector-borne diseases, integrating these approaches becomes key. Here we develop a framework to evaluate how clinical interventions (i.e., vaccination and medication can be integrated with transgenic vector manipulation strategies to prevent disease invasion and reduce disease incidence. We show that the ability of clinical interventions to accelerate disease suppression can depend on the nature of the transgenic manipulation deployed (e.g., whether vector population reduction or replacement is attempted. We find that making a specific, individual strategy highly effective may not be necessary for attaining public-health objectives, provided suitable combinations can be adopted. However, we show how combining only partially effective antimicrobial drugs or vaccination with transgenic vector manipulations that merely temporarily lower vector competence can amplify disease resurgence following transient suppression. Thus, transgenic vector manipulation that cannot be sustained can have adverse consequences-consequences which ineffective clinical interventions can at best only mitigate, and at worst temporarily exacerbate. This result, which arises from differences between the time scale on which the interventions affect disease dynamics and the time scale of host population dynamics, highlights the importance of accounting for the potential delay in the effects of deploying public health strategies on long-term disease incidence. We find that for systems at the disease-endemic equilibrium, even

    To determine different clinical presentationsand disease location demarcatedby upper and lower gastrointestinal endoscopyand relevant histopathologyin children diagnosed with inflammatory bowel disease (IBD). This is 5 years (2010 to 2015) retrospective studyconducted at the Aga Khan University Hospitalenrolling65admitted children between 6 months to 15years from either gender, diagnosed with IBD on clinical presentation, endoscopy and biopsy. Different clinical presentations at the time of diagnosis were noted in different categories of the disease. All patients underwent upper and lower (up to the terminal ileum) endoscopy with multiple punch biopsies and histologic assessment of mucosal specimens. All endoscopies were done by paediatric gastroenterologists at endoscopy suite of the hospital and all specimens were reported by the pathology department. ESPGHAN revised criteria for the diagnosis of inflammatory bowel disease in children and an adolescent was used to standardize our diagnosis. Extent of disease on endoscopy and relevant histopathology of the biopsy samples were noted at the time of diagnosis. Data was summarized using mean, standard deviation, numbers and percentages for different variables. Total 56 children were enrolled according to inclusion criteria. There were 34children (61.53%) diagnosed with ulcerative colitis (UC), 10 patients (16.92%) had Crohn'sDisease (CD) and 11 (21.53%) patients were labeled as Indeterminate colitis (IC). Mean age at onset of symptoms was10.03±2.44 and mean age at diagnosis was11.10±2.36. Abdominal pain (80%) and chronic diarrhea (70%) were common symptoms in CD whereas bloody diarrhea (79.41%) and rectal bleeding(64.70%)were common presentation in UC. Patients diagnosed with indeterminate colitis(IC) had similar clinical features as in UC patients. Only 7% patients had some extra-intestinal features in the form of joint pain and/or uveitis. Aspartate aminotransferase level (95.18 ±12.89) was relatively high in

    Background Short-term risk assessment tools for prediction of cardiovascular disease events are widely recommended in clinical practice and are used largely for single time-point estimations; however, persons with low predicted short-term risk may have higher risks across longer time horizons. Methods and Results We estimated short-term and lifetime cardiovascular disease risk in a pooled population from 2 studies of Peruvian populations. Short-term risk was estimated using the atherosclerotic cardiovascular disease Pooled Cohort Risk Equations. Lifetime risk was evaluated using the algorithm derived from the Framingham Heart Study cohort. Using previously published thresholds, participants were classified into 3 categories: low short-term and low lifetime risk, low short-term and high lifetime risk, and high short-term predicted risk. We also compared the distribution of these risk profiles across educational level, wealth index, and place of residence. We included 2844 participants (50% men, mean age 55.9 years [SD 10.2 years]) in the analysis. Approximately 1 of every 3 participants (34% [95% CI 33 to 36]) had a high short-term estimated cardiovascular disease risk. Among those with a low short-term predicted risk, more than half (54% [95% CI 52 to 56]) had a high lifetime predicted risk. Short-term and lifetime predicted risks were higher for participants with lower versus higher wealth indexes and educational levels and for those living in urban versus rural areas (PPeruvian adults were classified as low short-term risk but high lifetime risk. Vulnerable adults, such as those from low socioeconomic status and those living in urban areas, may need greater attention regarding cardiovascular preventive strategies. PMID:26254303

    Brain tissue analysis is necessary to confirm prion diseases. Clinically unsuspected cases may be identified through neuropathologic testing. National Alzheimer's Coordinating Center (NACC) Minimum and Neuropathologic Data Set for 1984 to 2005 were reviewed. Eligible patients had dementia, underwent autopsy, had available neuropathologic data, belonged to a currently funded Alzheimer's Disease Center (ADC), and were coded as having an Alzheimer's disease clinical diagnosis or a nonprion disease etiology. For the eligible patients with neuropathology indicating prion disease, further clinical information, collected from the reporting ADC, determined whether prion disease was considered before autopsy. Of 6000 eligible patients in the NACC database, 7 (0.12%) were clinically unsuspected but autopsy-confirmed prion disease cases. The proportion of patients with dementia with clinically unrecognized but autopsy-confirmed prion disease was small. Besides confirming clinically suspected cases, neuropathology is useful to identify unsuspected clinically atypical cases of prion disease. © The Author(s) 2015.

    Full Text Available Pecific aspects of cognitive impairments in patients with paranoid schizophrenia depending on the clinical characteristics of the disease have been studied. One hundred and thirty patients were examined. A clinico-psychological, experimental psychological and statistical methods were used. Three main types of cognitive deficiency with paranoid schizophrenia, associated with the onset, disease duration, and severity of psychiatric symptomology : 1 long-term course of the disease accompanied by the average level of clinical symptomology associated with abnormal attention and visuospatial functions; 2 late onset of the disease and unexpressed clinical symptomology combined with memory impairments; 3 acute onset and early age combined with the absence of cognitive impairments.

    Affective disorders and personality changes have long been considered pre-motor aspects of Parkinson's disease (PD). Many authors have used the term "premorbid personality" to define distinctive features of PD patients' personality characterized by reduced exploration of new environmental stimuli or potential reward sources ("novelty seeking") and avoidance behaviour ("harm avoidance") present before motor features. The functional correlates underlying the personality changes described in PD, implicate dysfunction of meso-cortico-limbic and striatal circuits. As disease progresses, the imbalance of neurotransmitter systems secondary to degenerative processes, along with dopamine replacement therapy, can produce a reversal of behaviours and an increase in reward seeking, laying the foundations for the emergence of the impulse control disorders. Personality disorders can be interpreted, therefore, as the result of individual susceptibility arising from intrinsic degenerative processes and individual personality features, in combination with extrinsic factors such as lifestyle, PD motor dysfunction and drug treatment. For a better understanding of personality disorders observed in PD and their relationship with the prodromal stage of the disease, prospective clinical studies are needed that correlate different personality profiles with other disease progression markers. Here, we review previous studies investigating the clinical, cognitive and behavioural correlates of personality traits in PD patients. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Multiple sclerosis (MS has a highly heterogenic course making prediction of long term outcome very difficult.The objective was to evaluate current and identify additional clinical factors that are linked to long term outcome of relapsing-remitting MS assessed by disability status 10 years after disease onset.This observational study included 793 patients with relapsing-remitting MS. Clinical factors hypothesized to influence long term outcome measured by EDSS scores 10 years after disease onset were analysed by Kaplan-Meier-estimates. Multinomial logistic regression models regarding mild (EDSS ≤2.5, moderate (EDSS 3.0-5.5 or severe (EDSS ≥6.0 disability were calculated to correct for confounders.Secondary progression was the strongest predictor of severe disability (Hazard ratio [HR] 503.8, 95% confidence interval [CI] 160.0-1580.1; p<0.001. Complete remission of neurological symptoms at onset reduced the risk of moderate disability (HR 0.42; CI 0.23-0.77; p = 0.005, while depression (HR 3.59; CI 1.14-11.24; p = 0.028 and cognitive dysfunction (HR 4.64; CI 1.11-19.50; p = 0.036 10 years after disease onset were associated with severe disability. Oligoclonal bands and pregnancy were not correlated with disability.We were able to identify clinically apparent chronic depression and cognitive dysfunction to be associated with adverse long term outcome in MS and to confirm that pregnancy has no negative impact. Additionally, we emphasize the positive predictive value of complete remission of initial symptoms.

    Short-term risk assessment tools for prediction of cardiovascular disease events are widely recommended in clinical practice and are used largely for single time-point estimations; however, persons with low predicted short-term risk may have higher risks across longer time horizons. We estimated short-term and lifetime cardiovascular disease risk in a pooled population from 2 studies of Peruvian populations. Short-term risk was estimated using the atherosclerotic cardiovascular disease Pooled Cohort Risk Equations. Lifetime risk was evaluated using the algorithm derived from the Framingham Heart Study cohort. Using previously published thresholds, participants were classified into 3 categories: low short-term and low lifetime risk, low short-term and high lifetime risk, and high short-term predicted risk.

    Alzheimer disease is a devastating neurodegenerative disorder affecting millions of Americans. It reduces the ability of the individual to remain independent, places a burden on caregivers, and substantially increases healthcare costs. New treatments are being tested in numerous clinical trials with the goal of preventing or delaying the onset of Alzheimer disease, slowing or modifying the disease's course, or finding a cure for patients with the disease. Alzheimer disease research can successfully proceed only if individuals who have this illness are willing to participate in clinical trials. However, recruitment and retention of subjects in clinical trials for Alzheimer disease is a challenging task. Furthermore, because of reductions in decision-making capacities of individuals with Alzheimer disease, clinical trials also need to involve caregivers. The present article delineates unique hurdles encountered in the recruitment process for Alzheimer disease clinical trials. The article also identifies strategies for effective recruitment of subjects in Alzheimer disease clinical trials, including guidelines to help principal investigators and clinical research coordinators reach recruitment goals.

    In spite of previous conflicting results, an adjuvant role of selenium in the treatment of Graves' disease (GD) hyperthyroidism has been proposed. To address this issue, a randomized clinical trial was carried out aimed at investigating whether selenium is beneficial on the short-term control of GD hyperthyroidism treated with methimazole (MMI). Thirty newly diagnosed hyperthyroid GD patients were randomly assigned to treatment with: (i) MMI or (ii) MMI plus selenium. Primary outcomes were: control of hyperthyroidism and clinical and biochemical manifestations of hyperthyroidism [heart rate, cholesterol, sex hormone-binding globulin (SHBG), hyperthyroidism symptoms] at 90 days. Baseline features of the two groups did not differ. Serum selenium at baseline was similar in the two groups and within the recommended range to define selenium sufficiency. Selenium increased with treatment in the MMI-selenium group and became significantly higher than in the MMI group. Serum malondialdehyde, a marker of oxidative stress, was similar in the two groups and decreased significantly with treatment, with no difference between groups. Administration of MMI was followed by a reduction of FT 3 and FT 4 , with no difference between groups. Heart rate, SHBG and symptoms of hyperthyroidism decreased, whereas total cholesterol increased in both groups with no difference between groups. Our study, carried out in a selenium-sufficient cohort of GD patients, failed to show an adjuvant role of selenium in the short-term control of hyperthyroidism. However, selenium might be beneficial in patients from selenium-deficient areas, as well as in the long-term outcome of antithyroid treatment.

  11. Clinical and Histologic Mimickers of Celiac Disease.

    Celiac disease is an autoimmune disorder of the small bowel, classically associated with diarrhea, abdominal pain, and malabsorption. The diagnosis of celiac disease is made when there are compatible clinical features, supportive serologic markers, representative histology from the small bowel, and response to a gluten-free diet. Histologic findings associated with celiac disease include intraepithelial lymphocytosis, crypt hyperplasia, villous atrophy, and a chronic inflammatory cell infiltrate in the lamina propria. It is important to recognize and diagnose celiac disease, as strict adherence to a gluten-free diet can lead to resolution of clinical and histologic manifestations of the disease. However, many other entities can present with clinical and/or histologic features of celiac disease. In this review article, we highlight key clinical and histologic mimickers of celiac disease. The evaluation of a patient with serologically negative enteropathy necessitates a carefully elicited history and detailed review by a pathologist. Medications can mimic celiac disease and should be considered in all patients with a serologically negative enteropathy. Many mimickers of celiac disease have clues to the underlying diagnosis, and many have a targeted therapy. It is necessary to provide patients with a correct diagnosis rather than subject them to a lifetime of an unnecessary gluten-free diet.

    Objective: Clinical characteristic, diagnosis and treatment of radiation urinary bladder disease induced by radiation therapy for cancers in the pelvis were inquired into for providing diagnostic basis. Methods: Statistical analysis for the clinical cases was carried out. Results: The incidence of radiation bladder diseases induced by radiation therapy of cervix cancer are about 0.8%-2.96%, with an average of 2.14%. Radiation bladder disease is divided into acute radiation cystitis, chronic radiation cystitis and radiation vesical fistula. Chronic radiation cystitis is seen most often in the clinic and its main clinical symptom is painless macroscopic hematuria, which is again subdivided into slight and severe degrees. Diagnosis should include history of exposure to radiation, which dose exceed the dose threshold, and typical clinical characteristics. Conclusion: The characteristics, types and diagnostic basis of radiation urinary bladder disease analyzed in this study can provide the reference for drawing up diagnostic standard

    The aim of this was to assess clinical features and outcome in pediatric-onset Takayasu's arteritis (TA). Retrospective data analysis of patients diagnosed with TA over last 13 years with onset before 18 years of age was done. Their presenting features, activity (by NIH criteria, ITAS2010, ITAS-A), disease extent (by DEI.Tak) and angiographic findings were retrieved from clinic files. Treatment received and follow-up data on disease activity and damage by TA damage score (TADS) were also analyzed. Wherever repeated angiography data were available, the same was analyzed. Values are expressed as median with interquartile range in brackets. There were 29 patients (19 females) with median age at diagnosis of 14 (13-16) years and delay to diagnosis of 1 (0.4-2) year. Common presenting symptoms were pulse loss (23/29) and hypertension (22/29). Patients had extensive disease at presentation with median DEI.Tak of 12 (9.5-15); 23/29 had elevated acute-phase reactants, and 28/29 were active at presentation [median ITAS2010 13 (8-15.5), ITAS-A 14 (10-17)]. Numano's type V was the commonest angiographic type (22/29). At a median follow-up of 2.4 (1.5-5.1) years, 2/20 were active whereas all had sustained damage despite a majority (17/20) being on immunosuppression. The median TADS was 8 (6.3-9.8) with pulse loss, claudication and hypertension being the commonest damage item. Two needed renal artery stenting to control hypertension. Angiographic assessment at least 2 years apart demonstrated disease progression in 5 of 6 patients despite immunosuppression. Significant damage accrued on follow-up despite immunosuppression and control of disease activity. Hypertension remains the major long-term morbidity.

    Full Text Available Charalampos Papagoras, Paraskevi V Voulgari, Alexandros A DrososRheumatology Clinic, Department of Internal Medicine, Medical School, University of Ioannina, Ioannina, GreeceAbstract: Adalimumab, a fully humanized monoclonal antibody against tumor necrosis factor-alpha (TNFα, has been evaluated in various randomized placebo-controlled trials in rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and juvenile idiopathic arthritis. In the short time frame of these trials adalimumab has been shown to be effective in reducing disease activity, slowing radiographic disease progression and improving patients’ quality of life, while at the same time demonstrating an acceptable safety profile. Furthermore, release of adalimumab on the market, prospective observational studies, as well as open-label extensions of the original double-blind trials have provided experience and data about the long-term efficacy and safety of the drug. Initial effectiveness, in terms of reducing disease activity, is sustained, while in most cases patients treated with adalimumab experienced a slower radiographic progression and consequently less disability and improved health-related quality-of-life outcomes. Moreover, long-standing treatment of thousands of patients with adalimumab outside the controlled context of clinical trials was not related to new safety signals, with the most common adverse events being respiratory infections. The most common serious adverse events seem to be tuberculosis reactivation, while a putative association with malignant lymphoma development is not yet proven. Besides, both of these adverse reactions pertain to the whole TNFα blocker group. In conclusion, adalimumab is a safe and effective option for the treatment of patients with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and juvenile idiopathic arthritis. Keywords: adalimumab, tumor necrosis factor-alpha, rheumatoid arthritis, ankylosing spondylitis

  16. Subjective cognitive decline: The first clinical manifestation of Alzheimer's disease?

    Directory of Open Access Journals (Sweden)

    Adalberto Studart Neto

    Full Text Available ABSTRACT Background: Mild cognitive impairment is considered as the first clinical manifestation of Alzheimer's disease (AD, when the individual exhibits below performance on standardized neuropsychological tests. However, some subjects before having a lower performance on cognitive assessments already have a subjective memory complaint. Objective: A review about subjective cognitive decline, the association with AD biomarkers and risk of conversion to dementia. Methods: We performed a comprehensive non-systematic review on PubMed. The keywords used in the search were terms related to subjective cognitive decline. Results: Subjective cognitive decline is characterized by self-experience of deterioration in cognitive performance not detected objectively through formal neuropsychological testing. However, various terms and definitions have been used in the literature and the lack of a widely accepted concept hampers comparison of studies. Epidemiological data have shown that individuals with subjective cognitive decline are at increased risk of progression to AD dementia. In addition, there is evidence that this group has a higher prevalence of positive biomarkers for amyloidosis and neurodegeneration. However, Alzheimer's disease is not the only cause of subjective cognitive decline and various other conditions can be associated with subjective memory complaints, such as psychiatric disorders or normal aging. The features suggestive of a neurodegenerative disorder are: onset of decline within the last five years, age at onset above 60 years, associated concerns about decline and confirmation by an informant. Conclusion: These findings support the idea that subjective cognitive complaints may be an early clinical marker that precedes mild cognitive impairment due to Alzheimer's disease.

    Industry sponsorship of clinical research of degenerative diseases of the spine has been associated with excessive positive published results as compared to research carried out without industry funding. We sought the rates of publication of clinical trials of degenerative diseases of the spine based on funding source as a possible explanation for this phenomenon. We reviewed all clinical trials registered at clinicaltrials.gov relating to degenerative diseases of the spine as categorized under six medical subject heading terms (spinal stenosis, spondylolisthesis, spondylolysis, spondylosis, failed back surgery syndrome, intervertebral disc degeneration) and with statuses of completed or terminated. These collected studies were categorized as having, or not having, industry funding. Published results for these studies were then sought within the clinicaltrials.gov database itself, PubMed and Google Scholar. One hundred sixty-one clinical trials met these criteria. One hundred nineteen of these trials had industry funding and 42 did not. Of those with industry funding, 45 (37.8%) had identifiable results. Of those without industry funding, 17 (40.5%) had identifiable results. There was no difference in the rates of publication of results from clinical trials of degenerative diseases of the spine no matter the funding source. Copyright © 2015 Elsevier Ltd.

    The aim of this study was to report the prevalence and nature of long-term diseases and their consequences in children under the age of 16 in Denmark, and to identify the socio-demographic determinants of disease. Parents and stepparents participating in the Danish Health and Morbidity Survey, 2000, were interviewed at home about long-term diseases, including impairments and sequelae after injury and disease, in children under the age of 16 living at home. Answers were given for 7,670 children, and diseases were coded according to ICD-10 by two doctors. Logistic regression analysis was used to identify the determinants and consequences of disease. A total of 16.2% of children had one or more long-term diseases, boys (17.5%) more frequently than girls (14.8%). The prevalence increased through the first six years of life. A social gradient was seen: children of parents with low socioeconomic status or with little education had a higher prevalence. The most frequent disease was asthma (4.9%). Also frequent were congenital disorders (1.6%), otitis media (1.4%) and hearing impairment (0.6%). Children with long-term disease suffered more frequently than others from poor health in general, recent sick leave and poor thriving. The figures for long-term disease reported by the parents participating in the study were in accordance with what was found in earlier studies, but stigmatising and less severe diseases, as well as periodically recurring diseases, were probably underreported. Attention should be paid to the high prevalence of asthma, to the poorer thriving and to the general health status of children with long-term disease, and to the social inequality in children's health.

    Objective: To evaluate the method and result of thyroid artery embolization as a new therapy for Graves disease. Methods: Ten patients with Graves disease underwent selective thyroid artery embolization. Totally 25 thyroid arteries were embolized with PVA microspheres. The indications to this therapy were as following: Graves disease with recurrent clinical symptoms or with leucopenia during the period of treating with administration of antithyroid drugs or recurrence after subtotal thyroidectomy. Results: Serum level of thyroid hormones dropped significantly [median FT 3 from 20.90 pmol/L (13.36-50.92 pmol/L) to 7.81 pmol/L (3.67-35.3 pmol/L), median FT 4 from 57.9 pmol/L (30.96-57.9 pmol/L) to 28.13 pmol/L (20.44-39.60 pmol/L), (P < 0.005)] and then followed-up for 5-8 months. The symptoms of hyperthyroidism were controlled in 7 patients and the remaining 3 cases were treated with lower dosage of antithyroid drug therapy. None serious complications were found. Conclusions: thyroid artery embolization represents a promising new method for treating Graves disease with safety and good clinical results. Further investigation would be required to assess its long-term effect

    Alzheimer's disease impairs long term memories for related events (e.g. faces with names) more than for single events (e.g. list of faces or names). Whether or not this associative or 'binding' deficit is also found in short-term memory has not yet been explored. In two experiments we investigated binding deficits in verbal short-term memory in Alzheimer's disease. Experiment 1: 23 patients with Alzheimer's disease and 23 age and education matched healthy elderly were recruited. Participants studied visual arrays of objects (six for healthy elderly and four for Alzheimer's disease patients), colours (six for healthy elderly and four for Alzheimer's disease patients), unbound objects and colours (three for healthy elderly and two for Alzheimer's disease patients in each of the two categories), or objects bound with colours (three for healthy elderly and two for Alzheimer's disease patients). They were then asked to recall the items verbally. The memory of patients with Alzheimer's disease for objects bound with colours was significantly worse than for single or unbound features whereas healthy elderly's memory for bound and unbound features did not differ. Experiment 2: 21 Alzheimer's disease patients and 20 matched healthy elderly were recruited. Memory load was increased for the healthy elderly group to eight items in the conditions assessing memory for single or unbound features and to four items in the condition assessing memory for the binding of these features. For Alzheimer's disease patients the task remained the same. This manipulation permitted the performance to be equated across groups in the conditions assessing memory for single or unbound features. The impairment in Alzheimer's disease patients in recalling bound objects reported in Experiment 1 was replicated. The binding cost was greater than that observed in the healthy elderly group, who did not differ in their performance for bound and unbound features. Alzheimer's disease grossly impairs the

    To provide information on currently ongoing clinical trials for Stargardt disease. We have searched the clinical trial register (www.clinicaltrials.gov) for the keyword "Stargardt" and list active ongoing studies. There are currently eight registered clinical trials enrolling patients with Stargardt disease; all in phase I or II aiming at four mechanisms of action: inhibition of the production of vitamin A toxic dimers, gene therapy restoring wild type transcription of the ABCA4 gene, neuroprotection preventing retinal cells from oxidative damage, and replacement of the damaged retinal pigment epithelium using stem cell therapy. The basic prerequisite for enrolment in the vast majority of clinical trials is confirmation of the clinical diagnosis by mutational analysis. The wide variety of therapies that are registered as clinical trials for Stargardt disease significantly raises the possibility that effective treatments will be available in the near future for this currently incurable condition and that molecular genetic testing should be increasingly considered.

    1990-05-01

    Lyme disease (also known as Lyme borreliosis) is an emerging, newly described infectious disease with diverse clinical manifestations. The disease is caused by the spirochetal agent Borrelia burgdorferi, which is transmitted to humans by the bite of certain species of Ixodes ticks harboring the organism. The most readily identifiable clinical feature is the distinctive skin lesion, erythema migrans. If recently infected patients go untreated, approximately 15% will develop neurologic conditions (most commonly facial nerve palsy), 8% will develop myocarditis (typically with heart block), and 60% will develop migratory mono- or pauci-articular arthritis. Diagnosis depends on clinical suspicion, recognition of the characteristic signs and symptoms, and appropriate testing for antibody to B. burgdorferi. Serology for Lyme disease, although in need of better standardization, is most useful in diagnosing patients with manifestations of Lyme disease other than erythema migrans. All manifestations of Lyme disease are potentially treatable with either a beta-lactam antibiotic (for instance penicillin, amoxicillin, or ceftriaxone) or a tetracycline preparation. However, the optimal antimicrobial regimen, including choice of drug, drug dose, route of administration, and length of therapy, is unknown. Other important areas for future research include Ixodes biology and control, improved laboratory tests for diagnosis and for assessing response to therapy, and vaccine development.

    Skeletal findings in infants with Menkes disease, the most characteristic of which are metaphyseal spurs, long-bone fractures and wormian bones, have been widely reported. However, the changes in skeletal features over time are not well known. The long-term findings differ completely from those initially observed and consist of undertubulation and metaphyseal flaring, similar to the findings seen in some types of bone dysplasia. The initial and long-term radiological features in an 8-year-old boy with Menkes disease are illustrated. (orig.)

    Approximately 36% of adult women in the United States are obese. Although obesity affects women similarly to men in terms of prevalence, there seem to be gender-specific differences in the pathophysiology, clinical manifestations, and treatment of obesity. Obesity is linked to comorbid diseases involving multiple organ systems, including the gastrointestinal tract, like gastroesophageal reflux disease, fatty liver disease, and gallstones. This article focuses on obesity in women, specifically the impact of obesity on gastrointestinal diseases and reproductive health, as well as the treatment of obesity in women.

    We present the results of a clinical and genetic reinvestigation of the Cypriot family affected by an X chromosomally inherited eye disease originally published by Taylor et al, who coined the term Episkopi blindness. The pedigree was extended to 160 members, including 16 affected males out of 48 males at risk for the disease, most of whom were seen by one of us (PA). Affected males are blind with no associated symptoms and apparently are not mentally retarded. Thirty-nine family members agre...

    Cushing disease is caused by excessive adrenocorticotropic hormone (ACTH) production by the pituitary adenoma. Transsphenoidal surgery is its first-line treatment. The incidence of Cushing disease in children and adolescents is so rare that long-term prognoses have yet to be made in most cases. We followed-up on a 16-year-old male Cushing disease patient who presented with rapid weight gain and growth retardation. The laboratory findings showed increased 24-hour urine free cortisol and lack of overnight cortisol suppression by low-dose dexamethasone test. The serum cortisol and 24-hour urine free cortisol, by high-dose dexamethasone test, also showed a lack of suppression, and a bilateral inferior petrosal sinus sampling suggested lateralization of ACTH secretion from the right-side pituitary gland. However, after a right hemihypophysectomy by the transsphenoidal approach, the 24-hour urine free cortisol levels were persistently high. Thus the patient underwent a total hypophysectomy, since which time he has been treated with hydrocortisone, levothyroxine, recombinant human growth hormone, and testosterone enanthate. Intravenous bisphosphonate for osteoporosis had been administered for three years. At his current age of 26 years, his final height had attained the target level range; his bone mineral density was normal, and his pubic hair was Tanner stage 4. This report describes the long-term treatment course of a Cushing disease patient according to growth profile, pubertal status, and responses to hormone replacement therapy. The clinical results serve to emphasize the importance of growth optimization, puberty, and bone health in the treatment management of Cushing disease patients who have undergone transsphenoidal surgery.

    Full Text Available Discussion continues as to whether de novo hypertension in pregnancy with significant proteinuria (pre-eclampsia; PE and non-proteinuric new hypertension (gestational hypertension; GH are parts of the same disease spectrum or represent different conditions. Non-pregnant hypertension, pregnancy and PE are all associated with oxidative stress. We have established a 6 weeks post-partum clinic for women who experienced a hypertensive pregnancy. We hypothesized that PE and GH could be distinguished by markers of oxidative stress; thiobarbituric acid reactive substances (TBARS and antioxidants (ferric ion reducing ability of plasma; FRAP. Since the severity of PE and GH is greater pre-term, we also compared pre-term and term disease. Fifty-eight women had term PE, 23 pre-term PE, 60 had term GH and 6 pre-term GH, 11 pre-existing (essential hypertension (EH without PE. Limited data were available from normotensive pregnancies (n=7 and non-pregnant controls (n=14. There were no differences in postpartum TBARS or FRAP between hypertensive states; TBARS (P=0.001 and FRAP (P=0.009 were lower in plasma of non-pregnant controls compared to recently-pregnant women. Interestingly FRAP was higher in preterm than term GH (P=0.013. In PE and GH, TBARS correlated with low density lipoprotein (LDL-cholesterol (P=0.036; this association strengthened with inclusion of EH ((P=0.011. The 10 year Framingham index for cardiovascular risk was positively associated with TBARS (P=0.003.Oxidative stress profiles do not differ between hypertensive states but appear to distinguish between recently-pregnant and non-pregnant states. This suggests that pregnancy may alter vascular integrity with changes remaining 6 weeks postpartum. LDL-cholesterol is a known determinant of oxidative stress in cardiovascular disease and we have shown this association to be present in hypertensive pregnancy further emphasizing that such a pregnancy may be revealing a pre-existing cardiovascular

    Pulmonary arterial (PA) hypertension in preterm infant is an important consequence of chronic lung disease of prematurity (CLD) arising mainly due to impaired alveolar development and dysregulated angiogenesis of the pulmonary circulation. Although PA pressure and resistance in these children normalise by school age, their pulmonary vasculature remains hyper-reactive to hypoxia until early childhood. Furthermore, there is evidence that systemic blood pressure in preterm born children with or without CLD is mildly increased at school age and in young adulthood when compared to term-born children. Arterial stiffness may be increased in CLD survivors due to increased smooth muscle tone of the pre-resistance and resistance vessels rather than the loss of elasticity in the large arteries. This review explores the long term effects of CLD on the pulmonary and systemic circulations along with their clinical correlates and therapeutic approaches. Copyright © 2012 Elsevier Ltd.

    Exercise training regimes can lead to improvements in measures of cardiorespiratory fitness (CRF), improved general health, and reduced morbidity and overall mortality risk. High intensity interval training (HIIT) offers a time-efficient approach to improve CRF in healthy individuals, but the relative benefits of HIIT compared to traditional training methods are unknown in across different disease cohorts. This systematic review and meta-analysis compares CRF gains in randomised controlled trials of short-term (HIIT vs. either no exercise control (CON) or moderate continuous exercise training (MCT) within diseased cohorts. Literature searches of the following databases were performed: MEDLINE, EMBASE, CINAHL, AMED, and PubMed (all from inception to 1st December 2017), with further searches of Clinicaltrials.gov and citations via Google Scholar. Primary outcomes were effect upon CRF variables; VO2peak and Anaerobic Threshold (AT). Thirty-nine studies met the inclusion criteria. HIIT resulted in a clinically significant increase in VO2peak compared with CON (mean difference (MD) 3.32 ml[BULLET OPERATOR]kg[BULLET OPERATOR]min; 95% CI 2.56 to 2.08). Overall HIIT provided added benefit to VO2peak over MCT (MD 0.79 ml[BULLET OPERATOR]kg[BULLET OPERATOR]min; 95% CI 0.20 to 1.39). The benefit of HIIT was most marked in patients with cardiovascular disease when compared to MCT (VO2peak (MD 1.66 ml[BULLET OPERATOR]kg[BULLET OPERATOR]min; 95% CI 0.60 to 2.73); AT (MD 1.61 ml[BULLET OPERATOR]kg[BULLET OPERATOR]min; 95% CI 0.33 to 2.90)). HIIT elicits improvements in objective measures of CRF within 8 weeks in diseased cohorts compared to no intervention. When compared to MCT, HIIT imparts statistically significant additional improvements in measures of CRF, with clinically important additional improvements in VO2peak in cardiovascular patients. Comparative efficacy of HIIT vs MCT combined with an often reduced time commitment may warrant HIIT's promotion as a viable clinical

    The diagnosis of acute rheumatic fever (RF) is based on clinical findings. However, during the chronic phase of the disease, the clinical approach is not sufficient for the follow-up of the patients and the Doppler echocardiography is a tool for the diagnosis of cardiac involvement. Prognostic variables that influence long-term outcomes are not well known. 462 patients with RF according to Jones criteria were studied, and followed-up from the initial attack to 13.6 ± 4.6 years. All patients underwent clinical assessment and Doppler echocardiography for the detection of heart valve involvement in the acute and chronic phases. Multivariate logistic regression analysis was used to identify the factors influencing long-term heart valve disease. Carditis occurred in 55.8% and subclinical valvulitis in 35.3% patients. In the chronic phase, 33% of the patients had significant valvular heart disease. No normal Doppler echocardiography exam was observed on patients who had severe valvulitis, although heart auscultation had become normal in 13% of these. In the multivariate analysis, only the severity of carditis and the mitral and/or aortic valvulitis were associated with significant valvular heart disease. Chorea or arthritis were protective factors for significant valvular heart disease, odds ratio 0.41 (95% C.I. 0.22 – 0.77) and 0.43 (95% C.I. 0.23 – 0.82), respectively. Our study suggests that the use of Doppler echocardiography during RF helps to identify prognostic factors regarding the development of significant valvular heart disease. Initial severe carditis is an important factor in the long-term prognosis of chronic RHD, whereas arthritis and chore during the initial episode of RF appears to be protective. Strict secondary prophylaxis should be mandatory in high risk patients

    The mode of presentation of coeliac disease has been changing to more atypical or silent disease. Few studies described the clinical presentation of adult coeliac disease in Ireland in recent years. We retrospectively collected the clinical data for all patients who had a diagnosis of coeliac disease made in our centre between January 07 and December 08. Forty seven adults, predominantly females (n = 30), had a confirmed diagnosis of coeliac disease made during the study period. In our patient cohort, the presenting symptom was diarrhoea in 19 (40%) patients, while 16 patients (34%) did not have any G.I. symptoms, 10 (21%) presented with anaemia. Females presented at a significantly younger age compared to males, with median ages at diagnosis of 44.5 and 57 years, respectively (p = 0.04). Females also presented more commonly with non G.I. symptoms (p = 0.07). The reasons behind this gender difference need further study.

    Parkinson's disease is a severe, progressive neuro degenerative disorder which is characterised by a degeneration of the dopamine containing cells and loss of dopamine transporters (DA) in substantia nigra. Earlier 123 I-β-CIT SPECT studies have demonstrated this loss of DA content in Parkinson's disease. Recently a new radioligand 123 I-FP-CIT, with faster kinetics than b-CIT became available for imaging of the DA transporter. The applicability of this radioligand was tested in a large clinical material with early and advanced Parkinson's disease using a one day protocol. 123 I-FP-CIT uptake was decreased in patients with Parkinson's disease and this was seen three hours after injection of the radioligand. In the Parkinson's disease group the uptake in the putamen was reduced more than in the caudate nucleus. Specific to non-specific striatal uptake ratios correlated with the Hoehn and Yahr stage. It appeared that 123 I-FP-CIT SPECT allows a significant discrimination between patients with Parkinson's disease and other movement disorders. The scintigraphic observations were correlated to clinical findings. The results will be presented and discussed

    The authors present the first case of peripheral avascular retina in a term male neonate with pancreatic exocrine insufficiency, atypical microvillus inclusion disease, flat tympanograms, and recurrent urinary tract infections. Clinical examination showed avascular peripheral retina to posterior zone II temporally, with a flat stage 1-like demarcation line, and no plus disease. Genetic testing results were normal. The patient developed peripheral neovascularization and underwent panretinal photocoagulation. This case likely represents mild Norrie disease, familial exudative vitreoretinopathy, or incontinentia pigmenti due to a Wnt signaling abnormality. While these conditions are usually more severe, a variable spectrum of Wnt abnormalities exists throughout the body. Copyright 2015, SLACK Incorporated.

    The CHRONIOUS system defines a powerful and easy to use framework which has been designed to provide services to clinicians and their patients suffering from chronic diseases. The system is composed of a wearable shirt that integrate several body sensors, a portable smart device and a central sub-system that is responsible for the long term storage of the collected patient's data. A multi-parametric expert system is developed for the analysis of the collected data using intelligent algorithms and complex techniques. Apart for the vital signals, dietary habits, drug intake, activity data, environmental and biochemical parameters are recorded. The CHRONIOUS platform is validated through clinical trials in several medical centers and patient's home environments recruiting patients suffering from Chronic Obstructive pulmonary disease (COPD) and Chronic Kidney Disease (CKD) diseases. The clinical trials contribute in improving the system's accuracy, while Pulmonologists and Nephrologists experts utilized the CHRONIOUS platform to evaluate its efficiency and performance. The results of the utilization of the system were very encouraging. The CHRONIOUS system has been proven to be a well-validated real-time patient monitoring and supervision platform, providing a useful tool for the clinician and the patient that would contribute to the more effective management of chronic diseases.

    Few studies have been reported from the Kingdom of Saudi Arabia (SA) to describe the clinical presentation and long term outcomes of subacute thyroiditis (SAT). Our aim was to review the demographic, anthropometric, clinical presentation, laboratory results, treatment, and disease outcome in Riyadh region and to compare those with results from different regions of the Kingdom and different parts of the world. We reviewed the medical files of patients who underwent thyroid uptake scan during an 8-year period in King Khalid University Hospital. Only 25 patients had confirmed diagnosis of thyroiditis. Age and gender distribution were similar to other studies. Most patients presented with palpitation, goiter, and weight change. Elevated thyroid hormones, suppressed thyroid-stimulating hormone, and elevated ESR were reported. Among those, 7 cases of SAT were recorded. β-Blockers were prescribed to 57% and nonsteroidal anti-inflammatory drugs to 29% of SAT. Long follow-up demonstrated that 85.7% of SAT cases recovered, while 14.3% developed permanent hypothyroidism. In conclusion, SAT is uncommon in the central region of SA. Compared to the western region, corticosteroid is not commonly prescribed, and permanent hypothyroidism is not uncommon. A nation-wide epidemiological study to explain these interprovincial differences is warranted. PMID:24803929

    Background Lyme disease is an emerging zoonotic infection in Canada. As the Ixodes tick expands its range, more Canadians will be exposed to Borrelia burgdorferi, the bacterium that causes Lyme disease. Objective To review the clinical diagnosis and treatment of Lyme disease for front-line clinicians. Methods A literature search using PubMed and restricted to articles published in English between 1977 and 2014. Results Individuals in Lyme-endemic areas are at greatest risk, but not all tick bites transmit Lyme disease. The diagnosis is predominantly clinical. Patients with Lyme disease may present with early disease that is characterized by a “bull’s eye rash”, fever and myalgias or with early disseminated disease that can manifest with arthralgias, cardiac conduction abnormalities or neurologic symptoms. Late Lyme disease in North America typically manifests with oligoarticular arthritis but can present with a subacute encephalopathy. Antibiotic treatment is effective against Lyme disease and works best when given early in the infection. Prophylaxis with doxycyline may be indicated in certain circumstances. While a minority of patients may have persistent symptoms, evidence does not demonstrate that prolonged courses of antibiotics improve outcome. Conclusion Clinicians need to be aware of the signs and symptoms of Lyme disease. Knowing the regions where Borrelia infection is endemic in North America is important for recognizing patients at risk and informing the need for treatment. PMID:29769842

    The aim of this study was to compare the performance and power of the best-established diagnostic biological markers as outcome measures for clinical trials in patients with mild cognitive impairment (MCI). Magnetic resonance imaging, F-18 fluorodeoxyglucose positron emission tomography markers, and Alzheimer's Disease Assessment Scale-cognitive subscale were compared in terms of effect size and statistical power over different follow-up periods in 2 MCI groups, selected from Alzheimer's Disease Neuroimaging Initiative data set based on cerebrospinal fluid (abnormal cerebrospinal fluid Aβ1-42 concentration-ABETA+) or magnetic resonance imaging evidence of Alzheimer disease (positivity to hippocampal atrophy-HIPPO+). Biomarkers progression was modeled through mixed effect models. Scaled slope was chosen as measure of effect size. Biomarkers power was estimated using simulation algorithms. Seventy-four ABETA+ and 51 HIPPO+ MCI patients were included in the study. Imaging biomarkers of neurodegeneration, especially MR measurements, showed highest performance. For all biomarkers and both MCI groups, power increased with increasing follow-up time, irrespective of biomarker assessment frequency. These findings provide information about biomarker enrichment and outcome measurements that could be employed to reduce MCI patient samples and treatment duration in future clinical trials.

    This study was carried out to assess the clinical characteristics and associated systemic diseases seen in patients diagnosed with absent contractility as per the Chicago Classification version 3.0, allowing us to propose a diagnostic algorithm for their etiologic testing. The Chicago Classification version 3.0 has redefined major and minor esophageal motility disorders using high-resolution esophageal manometry. There is a dearth of publications based on research on absent contractility, which historically has been associated with myopathic processes such as systemic sclerosis (SSc). We conducted a retrospective, multicenter study. Data of patients diagnosed with absent contractility were pooled from Cleveland Clinic, Cleveland, OH (January 2006 to July 2016) and Metrohealth Medical Center, Cleveland, OH (July 2014 to July 2016) and included: age, gender, associated medical conditions, surgical history, medications, and specific antibody testing. A total of 207 patients, including 57 male individuals and 150 female individuals, with mean age of 56.1 and 60.0 years, respectively, were included. Disease distribution was as follows: SSc (diffuse or limited cutaneous) 132, overlap syndromes 7, systemic lupus erythematosus17, Sjögren syndrome 4, polymyositis 3, and dermatomyositis 3. Various other etiologies including gastroesophageal reflux disease, postradiation esophagitis, neuromuscular disorders, and surgical complications were seen in the remaining cohort. Most practitioners use the term "absent contractility" interchangeably with "scleroderma esophagus"; however, only 63% of patients with absent contractility had SSc. Overall, 20% had another systemic autoimmune rheumatologic disease and 16% had a nonrheumatologic etiology for absent contractility. Therefore, alternate diagnosis must be sought in these patients. We propose an algorithm for their etiologic evaluation.

    A strict gluten-free diet is the cornerstone of treatment for coeliac disease. Studies of gluten-free diet adherence have rarely used validated instruments. There is a paucity of data on long-term adherence to the gluten-free diet in the adult population. To determine the long-term adherence to the gluten-free diet and potential associated factors in a large coeliac disease referral centre population. We performed a mailed survey of adults with clinically, serologically and histologically confirmed coeliac disease diagnosed ≥5 years prior to survey. The previously validated Celiac Disease Adherence Test was used to determine adherence. Demographic, socio-economic and potentially associated factors were analysed with adherence as the outcome. The response rate was 50.1% of 709 surveyed, the mean time on a gluten-free diet 9.9 ± 6.4 years. Adequate adherence (celiac disease adherence test score 75% of respondents. Perceived cost remains a barrier to adherence. Perceptions of effectiveness of gluten-free diet as well as its knowledge, are potential areas for intervention. © 2015 John Wiley & Sons Ltd.

    Morbihan's disease is characterized by chronic persistent facial edema of the upper half of the face, absence of typical diagnostic findings, and refractoriness to treatment. A 44-year-old man was diagnosed with Morbihan's disease based on clinical signs and histopathology, which showed dermal edema in upper dermis, discrete lymphocytic infiltrate without granulomatous reaction, and mast cell infiltration. After long-term therapy with intralesional triamcinolone a remarkable objective and subjective clinical response was observed. Reported cases of Morbihan's disease are reviewed, with respect to their treatment and histopathological findings. Mast cell infiltration has been observed on histopathology in most patients who responded to intralesional triamcinolone, suggesting a possible marker of response. The long-lasting response seen in our case indicates the efficacy of intralesional triamcinolone in this rare condition. © 2018 Wiley Periodicals, Inc.

    Mucosal inflammation must be carefully monitored to improve the long-term outcomes of patients with inflammatory bowel diseases (IBD). Patient-reported outcome measures (PROMs) are used increasingly to monitor disease activity in clinical practice and as endpoints in clinical trials. We performed a systematic review to provide an overview of the available PROMs on IBD activity and to evaluate their diagnostic value. A systematic search of the PubMed, Medline, Cochrane library, and Embase databases using defined keywords, identified 973 articles. These were screened by 2 independent reviewers, and 37 articles on development or validation of PROMs to assess IBD activity were identified for further analysis. Based on the recommendations of the Food and Drug Administration (FDA), the following measurement properties were evaluated: content, construct, and criterion validity; reliability; and responsiveness to change. In addition, data on ease of use in clinical practice were collected. Seventeen articles presenting 20 different PROMs were included the final analysis, although none met all the FDA-recommended criteria. Only 2 PROMs (patient-reported Harvey Bradshaw Index and Simple Clinical Colitis Activity Index scores) reported patient involvement during its development. Only 6 PROMs (patient-reported global assessment, patient assessment of disease activity, mobile health index for Crohn's disease, mobile health index for ulcerative colitis, patient-reported outcome derived from the Mayo score, and the 6-point Mayo score) were validated as markers of IBD activity, using findings from endoscopy as the reference standard; these PROMs identified patients with mucosal inflammation with area under the curve values of 0.63-0.82. The mobile health index for CD and UC scores had the best measurement properties for use in clinical practice and in clinical trials. In a systematic review, we identified more than 20 PROMS that have been developed and tested for their ability to

  5. Neuro degenerative diseases: clinical concerns

    Idiopathic Parkinson's disease (PD) and Alzheimer's disease (AD) are the main neuro-degenerative diseases (NDDs) seen clinically. They share some common clinical symptoms and neuro-pathological findings. The increase of life expectancy in the developed countries will inevitably contribute to enhance the prevalence of these diseases. Behavioral disorders, common in NDDs, will produce major care management challenges. Idiopathic Parkinson's disease corresponds to a histopathological diagnosis, based on the observation of a de-pigmentation and a neuronal loss in the substantia nigra, as well as on the presence of intra-neuronal inclusion bodies. AD is insidious with slowly progressive dementia in which the decline in memory constitutes the main complaint. The diagnosis of definite AD requires the presence of clinical criteria as well as the histopathological confirmation of brain lesions. The two main lesions are the presence of senile plaques and neuro-fibrillary tangles. Positron emission tomography (PET) explores cerebral metabolism and neurotransmitter kinetics in NDDs using principally [ 18 F]-deoxyglucose and [ 18 F]-dopa. Nigrostriatal dopaminergic function is altered in PD, as evidenced by the low uptake of [ 18 F]-dopa in the posterior putamen as compared to anterior putamen and caudate nucleus. In contrast, [ 18 F]-dopa uptake is equally depressed in all striatal structures in progressive supra-nuclear palsy. Regional glucose metabolism at rest is preserved in elderly once cerebral atrophy is taken into account. On the contrary, glucose metabolism is globally reduced in AD, with marked decrease in the parietal and temporal regions. PET has proved to be useful to study in vivo neurochemical processes in patients suffering from NDDs. The potential of this approach is still largely unexploited, and depends on new ligand production to establish early diagnosis and treatment follow-up. (author)

    The implementation of electronic medical records (EMR) is becoming increasingly common. Error and data loss reduction, patient-care efficiency increase, decision-making assistance and facilitation of event surveillance, are some of the many processes that EMRs help improve. In addition, they show a lot of promise in terms of data collection to facilitate observational epidemiological studies and their use for this purpose has increased significantly over the recent years. Even though the quantity and availability of the data are clearly improved thanks to EMRs, still, the problem of the quality of the data remains. This is especially important when attempting to determine if an event has actually occurred or not. We sought to assess the sensitivity, specificity, and agreement level of a codes-based algorithm for the detection of clinically relevant cardiovascular (CaVD) and cerebrovascular (CeVD) disease cases, using data from EMRs. Three family physicians from the research group selected clinically relevant CaVD and CeVD terms from the international classification of primary care, Second Edition (ICPC-2), the ICD 10 version 2015 and SNOMED-CT 2015 Edition. These terms included both signs, symptoms, diagnoses and procedures associated with CaVD and CeVD. Terms not related to symptoms, signs, diagnoses or procedures of CaVD or CeVD and also those describing incidental findings without clinical relevance were excluded. The algorithm yielded a positive result if the patient had at least one of the selected terms in their medical records, as long as it was not recorded as an error. Else, if no terms were found, the patient was classified as negative. This algorithm was applied to a randomly selected sample of the active patients within the hospital's HMO by 1/1/2005 that were 40-79 years old, had at least one year of seniority in the HMO and at least one clinical encounter.

    Chronic obstructive pulmonary disease (COPD) is a leading cause of disability in all its stages, and death in patients with moderate or severe obstruction. At present, COPD is suboptimally managed; current health is often not measured properly and hardly taken into account in management plans, and the future risk for patients with regard to health status and quality of life is not being evaluated. This review addresses the effect of COPD on the lives of patients and examines ways in which existing assessment tools meet physicians’ needs for a standardized, simple method to measure consistently the full impact of COPD on patients in routine clinical practice. Current assessment of COPD severity tends to focus on airflow limitation, but this does not capture the full impact of the disease and is not well correlated with patient perception of symptoms and health-related quality of life. Qualitative studies have demonstrated that patients usually consider COPD impact in terms of frequency and severity of symptoms, and physical and emotional wellbeing. However, patients often have difficulty expressing their disease burden and physicians generally have insufficient time to collect this information. Therefore, it is important that methods are implemented to help generate a more complete understanding of the impact of COPD. This can be achieved most efficiently using a quick, reliable, and standardized measure of disease impact, such as a short questionnaire that can be applied in daily clinical practice. Questionnaires are precision instruments that contribute sensitive and specific information, and can potentially help physicians provide optimal care for patients with COPD. Two short, easy-to-use, specific measures, ie, the COPD Assessment Test and the Clinical COPD Questionnaire, enable physicians to assess patients’ health status accurately and improve disease management. Such questionnaires provide important measurements that can assist primary care physicians to

    Clinical archetypes are modular definitions of clinical data, expressed using standard or open constraint-based data models as the CEN EN13606 and openEHR. There is an increasing archetype specification activity that raises the need for techniques to associate archetypes to support better management and user navigation in archetype repositories. This paper reports on a computational technique to generate tentative archetype associations by mapping them through term clusters obtained from the UMLS Metathesaurus. The terms are used to build a bipartite graph model and graph connectivity measures can be used for deriving associations.

    This study aimed to characterize juvenile myasthenia gravis in a national population-based cohort in Norway, and to evaluate long-term outcome and potential differences correlated with prepubertal versus postpubertal disease onset. Patients with onset of myasthenia gravis aged ≤18 years were identified through multiple strategies. Retrospective clinical data were collected by means of medical charts. All patients had an updated clinical examination. Cases were divided into prepubertal and postpubertal onset using age 12 years as the cut off. In total, 75 patients were identified of whom 63 were included in the study: 21 in the prepubertal and 42 in the postpubertal onset group. There was a female preponderance in both groups. In total, 59% presented with ocular symptoms, but the great majority of patients in both groups generalized during the two first years of the disease. Myasthenic crisis was more frequent in the prepubertal onset group. All patients were initially treated with pyridostigmine, 26 with steroids, and 17 with other immunosuppressive treatment. The postpubertal cases were more often treated with immunosuppressive therapy. Fifty patients (79%) underwent thymectomy. The general outcome was favourable: 57% became asymptomatic and only four subjects failed to attain clinical improvement. One-third had at least one additional autoimmune disease. Despite frequent symptom generalization and a subgroup of prepubertal onset with severe disease, the long-term outcome was good, especially in the thymectomized prepubertal onset group. Polyautoimmunity occurred in both groups in one-third. Copyright © 2017 European Paediatric Neurology Society. Published by Elsevier Ltd. All rights reserved.

    Despite advances in treatment of alcohol use disorders that focus on increasing abstinence and reducing recidivism, alcoholic liver disease (ALD) is projected to be the major cause of cirrhosis and its complications. Malnutrition is recognized as the most frequent complication in ALD, and despite the high clinical significance, there are no effective therapies to reverse malnutrition in ALD. Malnutrition is a relatively imprecise term, and sarcopenia or skeletal muscle loss, the major component of malnutrition, is primarily responsible for the adverse clinical consequences in patients with liver disease. It is, therefore, critical to define the specific abnormality (sarcopenia) rather than malnutrition in ALD, so that therapies targeting sarcopenia can be developed. Skeletal muscle mass is maintained by a balance between protein synthesis and proteolysis. Both direct effects of ethanol (EtOH) and its metabolites on the skeletal muscle and the consequences of liver disease result in disturbed proteostasis (protein homeostasis) and consequent sarcopenia. Once cirrhosis develops in patients with ALD, abstinence is unlikely to be effective in completely reversing sarcopenia, as other contributors including hyperammonemia, hormonal, and cytokine abnormalities aggravate sarcopenia and maintain a state of anabolic resistance initiated by EtOH. Cirrhosis is also a state of accelerated starvation, with increased gluconeogenesis that requires amino acid diversion from signaling and substrate functions. Novel therapeutic options are being recognized that are likely to supplant the current "deficiency replacement" approach and instead focus on specific molecular perturbations, given the increasing availability of small molecules that can target specific signaling components. Myostatin antagonists, leucine supplementation, and mitochondrial protective agents are currently in various stages of evaluation in preclinical studies to prevent and reverse sarcopenia, in cirrhosis in

    Gastroesophageal reflux disease (GERD) is an emerging disease, and can impair quality of life and sleep. This study aimed to investigate whether GERD patients with different timings of reflux symptoms have different clinical characteristics. This study prospectively enrolled individuals who underwent upper gastrointestinal endoscopy during a health checkup. Each participant completed all questionnaires including Reflux Disease Questionnaire, Nighttime GERD questionnaire, Pittsburg Sleep Quality Index, Taiwanese Depression Questionnaire, and State-Trait Anxiety Inventory. Combined reflux was defined as the timing of reflux symptoms occurring at both daytime and nighttime. A total of 2604 participants were enrolled. Of them, 651 symptomatic GERD patients, according to the Reflux Disease Questionnaire score, were recruited for final analysis. Of them, 224 (34.4%) had erosive esophagitis on endoscopy. According to the timing of reflux symptoms, 184 (28.3%) were assigned to the daytime reflux group, 71 (10.9%) to the nighttime reflux group, and 396 (60.8%) to the combined reflux group. In post hoc analysis, the combined reflux group had a significantly higher Reflux Disease Questionnaire score than the daytime reflux group (p reflux groups had higher body mass index and longer duration (> 12 years) of education than the daytime reflux group (p reflux of have more troublesome symptoms than those with daytime reflux. GERD patients with different timings of reflux symptoms have different clinical characteristics in terms of body mass index and duration of education, but not in terms of esophageal inflammation, quality of sleep, and psychosocial status.

    Full Text Available The review is dedicated to treatment of allergic diseases in children, particularly to the use of the 2nd generation antihistamine. It demonstrates that mediator histamine has the crucial role in pathophysiology of the allergic reaction. Antihistamines block histamine action aimed at H1 receptors by way of competitive inhibition. The 2nd generation antihistamines are the drugs of choice for the treatment of allergic diseases due to the absence of sedative effect. The review presents clinical and pharmacological description of the selective 2nd generation antihistamine cetirizine, efficacy and safety of which have been appraised in numerous long-term clinical studies in children with allergic rhinitis, urticaria and atopic dermatitis.

    We studied the effect of long-term alglucerase/imiglucerase (Ceredase®/Cerezyme®, Genzyme, a Sanofi company, Cambridge, MA, USA) treatment on hematological, visceral, and bone manifestations of Gaucher disease type 1 (GD1). The International Collaborative Gaucher Group (ICGG) Gaucher Registry identified GD1 patients treated with alglucerase/imiglucerase who had dose and clinical data at first infusion and after 10 years of follow-up. Data for hemoglobin, platelet count, organ volumes, bone pain, and bone crisis were analyzed. Tests of the null hypothesis (no change from first infusion to 10 years) were performed using t tests for within-patient absolute change in continuous measurements and McNemar/chi-square tests for change in distributions using categorical values. An alpha level of 0.05 designated statistical significance. As of October 2011, 557 nonsplenectomized and 200 splenectomized patients met the inclusion criteria. The majority of GD1 patients had at least one N370S allele. Compared with nonsplenectomized patients at first infusion, splenectomized patients had lower percentages of anemia (26.0 % vs. 42.8 %) and thrombocytopenia (14.2 % vs. 76.3 %), similar percentages of moderate or severe hepatomegaly (81.2 % vs. 80.0 %), and higher percentages of bone pain (88.9 % vs. 52.4 %) and bone crises (38.3 % vs. 16.0 %). After 10 years, both groups showed significant (p < 0.05) improvements in mean hemoglobin levels, platelet count, liver, and spleen (nonsplenectomized) volumes, and bone crises. Initial dosing in both groups ranged from <15 U/kg to ≤90 U/kg every 2 weeks. After 10 years, the majority was receiving 15 to ≤45 U/kg every 2 weeks. Ten years of imiglucerase treatment results in sustainable improvements in all GD1 parameters.

    Full Text Available OBJECTIVE Implementing cross-mapping of Nursing language terms with the terminology of NANDA International, contained in records of patients with Parkinson's disease in rehabilitation. METHOD Descriptive study of cross mapping, carried out in three steps. A simple random sample of 67 files of patients who participated in the rehabilitation in the period between March 2009 and April 2013. RESULTS We identified 454 terms of Nursing language that resulted in 54 diagnoses after cross-mapping, present in 11 of the 13 taxonomy domains. The most mapped diagnosis was "Impaired urinary elimination" (59.7%, followed by "Urgent urinary incontinence" (55.2%, "Willingness to self-control improved health" (50.7%, "Constipation" (47.8% and "Compromised physical mobility" (29.9%. Seven described terms were not mapped due to a corresponding defining characteristic being absent. CONCLUSION It was possible to determine the profile of patients, as well as the complexity of nursing care in the rehabilitation of patients with Parkinson's disease.

    Parkinsonian syndromes include idiopathic Parkinson's disease (IPD), other neurodegenerative diseases with parkinsonism, the so-called atypical parkinsonian syndromes, and symptomatic parkinsonian syndromes, such as Wilson's disease. IPD is the most frequent disease with parkinsonism as the main clinical feature and is responsible for approx. 80% of all parkinsonian syndromes. Atypical parkinsonian syndromes are the most important differential diagnoses of IPD. The two most frequent types are multiple system atrophy (MSA) and progressive supranuclear palsy (PSP). For clinical diagnosis it is essential to take a careful medical history and to examine the patients physically in regular intervals. However, various clinico-pathological studies have shown that approx. 25% of patients with clinical diagnosis of IPD may have other causes of parkinsonism. Selected technical investigations, in particular functional imaging of the central dopaminergic system using PET or SPECT, may help to make clinical diagnosis more secure. This paper reviews the clinical features and diagnostic findings in diseases with parkinsonism and summarises the difficulties in establishing early and differential diagnoses. (orig.) [de

    Background The literature suggests a lack of consensus on the use of terms related to coeliac disease (CD) and gluten. Methods A multi-disciplinary task force of 16 physicians from 7 countries used the electronic database PubMed to review the literature with regards to CD-related terms up to January 2011. Teams of physicians then suggested a definition for each term, followed by feedback of these definitions through a web survey on definitions, discussions during a meeting in Oslo, and phone conferences. We evaluated the following terms (in alphabetical order): Coeliac disease and the following descriptors of CD: asymptomatic, atypical, classical, latent, non-classical, overt, paediatric classical, potential, refractory, silent, subclinical, symptomatic, typical, CD serology, CD autoimmunity, genetically at risk of CD, dermatitis herpetiformis, gluten, gluten ataxia, gluten intolerance, gluten sensitivity, and gliadin-specific antibodies. Results CD was defined as “a chronic small intestinal immune-mediated enteropathy precipitated by exposure to dietary gluten in genetically predisposed individuals”. Classical CD was defined as “CD presenting with signs and symptoms of malabsorption. Diarrhoea, steatorrhoea, weight loss or growth failure is required.” We suggest that “gluten-related disorders” is the umbrella term for all diseases triggered by gluten and that the term gluten intolerance is not to be used. Other definitions are presented in the paper. Conclusion This paper presents the Oslo definitions for CD-related terms. PMID:22345659

    The primary treatment for end-stage lung disease is lung transplantation. However, donor organ shortage remains a major barrier for many patients. In recent years, techniques for maintaining lungs ex vivo for evaluation and short-term (advance to more complex interventions for lung repair and regeneration, the need for a long-term organ culture system becomes apparent. Herein we describe a novel clinical scale bioreactor capable of maintaining functional porcine and human lungs for at least 72 h in isolated lung culture (ILC). The fully automated, computer controlled, sterile, closed circuit system enables physiologic pulsatile perfusion and negative pressure ventilation, while gas exchange function, and metabolism can be evaluated. Creation of this stable, biomimetic long-term culture environment will enable advanced interventions in both donor lungs and engineered grafts of human scale. Copyright © 2015 Elsevier Ltd.

    Objective: This study evaluated the safety and long-term outcomes of drug-eluting stents in septuagenarians with coronary artery disease. Methods: Two hundred and thirty-nine consecutive patients with coronary artery disease underwent drug-eluting stenting, including 88 patients aged ≥70 years (group A) and 151 aged <70 years (group B). Baseline clinical characteristics, procedural success rate, occurrence of cardiac events during follow-up were recorded and compared between the two groups. Results: Procedural success rate and complications were similar for the two groups. During follow-up, group A had higher recurrence rate of chest pain than group B (23.9% vs. 7.3%, P<0.001), and occurrence of cardiac events was higher in group A than in group B (5.7% vs. 2.7%, P<0.296). There was no significant difference in the frequency of restenosis between the two groups. Conclusions: Drug-eluting stent implantation for septuagenarians with coronary artery disease is safe but may have more recurrence of angina than younger ones during long-term follow-up. (authors)

    Interest in short-term global health experiences to underserviced populations has grown rapidly in the last few decades. However, there remains very little research on what participants can expect to encounter. At the same time, it has been suggested that in order for physicians and workers to provide safe and effective care, volunteers should have a basic understanding of local culture, health systems, epidemiology, and socioeconomic needs of the community before arriving. Our objective was to add to the limited literature on what short-term global health trips can expect to encounter through a cross-sectional study of patient demographics, socioeconomic markers, and the prevalence of diseases encountered on a short-term medical service trip to Lima, Peru. Descriptive analysis was conducted on clinic data collected from patients living in Pamplona Alta and Pamplona Baja, Lima, Peru, in July 2015. We found that volunteers encountered mainly female patients (70.8%), and that there were significant socioeconomic barriers to care including poverty, poor housing, environmental exposures, and lack of continuity of health care. Analysis of the disease prevalence found a high proportion of acute and chronic musculoskeletal pain in the adult populations (18.8% and 11.4%, respectively), and a high presentation of upper respiratory tract infections (25.4%) and parasites (22.0%) in the pediatric group. These findings can be used by future short-term medical service trips to address potential gaps in care including the organization of weekend clinics to allow access to working men, and the use of patient education and nonpharmacological management of acute and chronic disease.

    Gaucher disease (GD), one of the most prevalent lysosomal storage diseases, is associated with glucocerebroside accumulation in cells of the monocyte-macrophage system in various organs, including the liver. Evaluating and managing liver disease in patients with Gaucher disease may be challenging. While hepatic involvement is common in Gaucher disease, its severity, and clinical significance span a wide spectrum, ranging from sub-clinical involvement to liver cirrhosis with its associated complications including portal hypertension. Apart from liver involvement in Gaucher disease, patients with may also suffer from other comorbidities involving the liver. That Gaucher disease itself can mimic hepatic lesions, affect laboratory tests used to characterize liver disease, and may be associated with non-cirrhotic portal hypertension, complicates the diagnostic approach even more. Better understanding of liver involvement in Gaucher disease can spare patients unnecessary invasive testing, and assist physicians in decision making when evaluating patients with Gaucher disease suspected for significant liver disease. This review describes the various clinical manifestations, laboratory and imaging abnormalities that may be encountered when following patients with Gaucher disease for liver involvement. The mechanism for liver disease are discussed, as well as the possible hepato-protective effect of glucocerebroside, and the a diagnostic and treatment approaches. Copyright © 2016 Elsevier Inc.

    The periodontal disease during pregnancy of women with rheumatic valve disease imply infective endocarditis risks and higher rate of preterm birth and low birth weight. To study the periodontal disease rate of women with rheumatic valve disease during pregnancy. We studied 140 pregnant women who included 70 patients with rheumatic valve disease and 70 healthy women. The periodontal examination included: 1) periodontal clinical exam regard the follow variables: a) probing depth; b) gingival margin; c) clinical attachment level; d) bleeding on probing; e) plaque index and f) gingival index; and 2) microbiological test was performed in samples serum and gingival crevicular fluid and considered positive controls to Porphyromonas gingivalis, Tannerella forsithia e Aggregobacter actinomycetemcomitans. Age and parity were similar between groups; as single or combined the mitral valve disease was prevalent among the rheumatic valve lesion in 45 (32.1%) e 20 (28.5%) cases, respectively. Among the periodontal variables gingival margin (p=0.01) and plaque index (p=0.04) were different between groups. The periodontal disease was identified in 20 (14,3%) pregnant women, seven (10%) of them were patients with valve rheumatic disease and the remain 13 (18,6%) were healthy women, its percentual was not different between groups (p=0,147). Microbiological analyses of oral samples showed higher percentual of P. gingivalis in healthy pregnant women (p=0.004). The clinical and microbiological study during pregnancy showed comparable incidence of periodontal disease between women with rheumatic valve disease and healthy women.

    Duchenne muscular dystrophy (DMD) is the most commonly inherited neuromuscular disease. Therapeutic agents for the treatment of rare disease, namely "orphan drugs", have recently drawn the attention of researchers and pharmaceutical companies. To ensure the successful conduction of clinical trials to evaluate novel treatments for patients with rare diseases, an appropriate infrastructure is needed. One of the effective solutions for the lack of infrastructure is to establish a network of rare diseases. To accomplish the conduction of clinical trials in Japan, the Muscular dystrophy clinical trial network (MDCTN) was established by the clinical research group for muscular dystrophy, including the National Center of Neurology and Psychiatry, as well as national and university hospitals, all which have a long-standing history of research cooperation. Thirty-one medical institutions (17 national hospital organizations, 10 university hospitals, 1 national center, 2 public hospitals, and 1 private hospital) belong to this network and collaborate to facilitate clinical trials. The Care and Treatment Site Registry (CTSR) calculates and reports the proportion of patients with neuromuscular diseases in the cooperating sites. In total, there are 5,589 patients with neuromuscular diseases in Japan and the proportion of patients with each disease is as follows: DMD, 29 %; myotonic dystrophy type 1, 23 %; limb girdle muscular dystrophy, 11 %; Becker muscular dystrophy, 10 %. We work jointly to share updated health care information and standardized evaluations of clinical outcomes as well. The collaboration with the patient registry (CTSR), allows the MDCTN to recruit DMD participants with specific mutations and conditions, in a remarkably short period of time. Counting with a network that operates at a national level is important to address the corresponding national issues. Thus, our network will be able to contribute with international research activity, which can lead to

    This study sought to determine whether mobile health (mHealth) device assessments used as clinical decision support tools at the point-of-care can reduce the time to treatment and improve long-term outcomes among patients with rheumatic and structural heart diseases (SHD). Newly developed smartphone-connected mHealth devices represent promising methods to diagnose common diseases in resource-limited areas; however, the impact of technology-based care on long-term outcomes has not been rigorously evaluated. A total of 253 patients with SHD were randomized to an initial diagnostic assessment with wireless devices in mHealth clinics (n = 139) or to standard-care (n = 114) in India. mHealth clinics were equipped with point-of-care devices including pocket-echocardiography, smartphone-connected-electrocardiogram blood pressure and oxygen measurements, activity monitoring, and portable brain natriuretic peptide laboratory testing. All individuals underwent comprehensive transthoracic echocardiography to assess the severity of SHD. The primary endpoint was the time to referral for therapy with percutaneous valvuloplasty or surgical valve replacement. Secondary endpoints included the probability of a cardiovascular hospitalization and/or death over 1 year. An initial mHealth assessment was associated with a shorter time to referral for valvuloplasty and/or valve replacement (83 ± 79 days vs. 180 ± 101 days; p Mobile Health Device Assessments in Modern Structural Heart Disease Clinics; NCT02881398).

    Full Text Available To determine the long-term health and function of transplanted dopamine neurons in Parkinson’s disease (PD patients, the expression of dopamine transporters (DATs and mitochondrial morphology were examined in human fetal midbrain cellular transplants. DAT was robustly expressed in transplanted dopamine neuron terminals in the reinnervated host putamen and caudate for at least 14 years after transplantation. The transplanted dopamine neurons showed a healthy and nonatrophied morphology at all time points. Labeling of the mitochondrial outer membrane protein Tom20 and α-synuclein showed a typical cellular pathology in the patients’ own substantia nigra, which was not observed in transplanted dopamine neurons. These results show that the vast majority of transplanted neurons remain healthy for the long term in PD patients, consistent with clinical findings that fetal dopamine neuron transplants maintain function for up to 15–18 years in patients. These findings are critically important for the rational development of stem-cell-based dopamine neuronal replacement therapies for PD.

    During the course of the disease, most patients with Crohn’s disease (CD) may eventually develop a stricturing or a perforating complication, and a significant number of patients with both CD and ulcerative colitis will undergo surgery. In recent years, research has focused on the determination of factors important in the prediction of disease course in inflammatory bowel diseases to improve stratification of patients, identify individual patient profiles, including clinical, laboratory and molecular markers, which hopefully will allow physicians to choose the most appropriate management in terms of therapy and intensity of follow-up. This review summarizes the available evidence on clinical, endoscopic variables and biomarkers in the prediction of short and long-term outcome in patients with inflammatory bowel diseases.

    Complex internal carotid artery disease presents a surgical challenge because limitations and difficulty are encountered with either clipping or endovascular treatment. Our review of previous reports suggests that no current vascular assessment can accurately predict occurrence of ischemic complications after internal carotid artery ligation. The present study concerns long-term clinical outcome of radial artery grafting followed by parent artery trapping or proximal occlusion for management of these difficult lesions. Between September 1997 and October 2007, we performed radial artery grafting followed immediately by parent artery occlusion in 20 sides of 19 patients with complex internal carotid arteries disease with follow-up for more than 36 months (5 men, 14 women; mean follow-up duration, 62 months). All patients underwent postoperative MRI and MR angiography (MRA) every year to assess graft patency, ischemic complications, and de novo aneurysm. Another 20 carotid aneurysms with visual disturbance were assessed concerning outcome. Among 13 patients with cranial nerve (III and VI) disturbances, all dysfunctions were improved in cases treated within 8 months of onset to operation. On the other hand, patients with second cranial nerve disturbances were not improved in cases treated after 4 months of onset. No long-term complications were discovered with MRI and MRA. With appropriate attention to surgical technique, radial artery grafting followed by acute parent artery occlusion is a safe treatment for complex internal carotid artery aneurysms. Long-term safety is satisfactory, with no delayed complications such as graft stenosis, ischemic complications or de novo aneurysm formations in follow-up periods of more than 3 years. Good clinical outcome of cranial nerve palsy was achieved in patients treated within 8 months of onset for cranial nerve (CN) III and VI, and 4 of CN II palsy. (author)

    BACKGROUND: Despite men being less prone to develop autoimmune diseases, male sex has been associated with a more severe disease course in several systemic autoimmune diseases. In the present study, we aimed to investigate differences in the clinical presentation of primary Sjögren's syndrome (p......SS) between the sexes and establish whether male sex is associated with a more severe form of long-term pSS. METHODS: Our study population included 967 patients with pSS (899 females and 68 males) from Scandinavian clinical centers. The mean follow-up time (years) was 8.8 ± 7.6 for women and 8.5 ± 6.2 for men...... (ns). Clinical data including serological and hematological parameters and glandular and extraglandular manifestations were compared between men and women. RESULTS: Male patient serology was characterized by more frequent positivity for anti-Ro/SSA and anti-La/SSB (p = 0.02), and ANA (p = 0...

    In the setting of clinically suspected Legg-Calve-Perthes (LCP) disease and negative/equivocal radiographs, contrast-enhanced MRI can be performed to confirm the diagnosis. To determine the frequency of unexpected causes of hip pain as identified by MRI in children with clinically suspected LCP disease and negative/equivocal radiographs. All pediatric contrast-enhanced MRI examinations of the pelvis and hips performed between January 2000 and February 2009 to evaluate for possible LCP disease in the setting of negative/equivocal radiographs were identified. MRI examinations performed to evaluate for secondary avascular necrosis were excluded. Imaging reports were retrospectively reviewed for unexpected clinically important causes of hip pain. Thirty-six pediatric patients underwent contrast-enhanced MRI examinations for clinically suspected LCP disease in the setting of negative/equivocal radiographs. Twenty-two (61%) imaging studies were normal, while four (11%) imaging studies demonstrated findings consistent with LCP disease. Ten (28%) imaging studies revealed unexpected clinically important causes of hip pain, including nonspecific unilateral joint effusion and synovitis (n = 7, juvenile chronic arthritis was eventually diagnosed in 3 patients), sacral fracture (n = 1), apophyseal injury (n = 1), and femoral head subluxation (n = 1). MRI frequently reveals unexpected clinically important causes of hip pain in children with suspected LCP disease and negative/equivocal radiographs. (orig.)

    Full Text Available Background/Aims: Intestinal Behçet's disease (BD is an immune-mediated inflammatory disorder. We followed up the patients and evaluated safety profile and effectiveness of adalimumab for the treatment of intestinal BD through 100 weeks rolled over from the 52 week clinical trial (NCT01243671.Methods: Patients initiated adalimumab therapy at 160 mg at week 0, followed by 80 mg at week 2, followed by 40 mg every other week until the end of the study. Long-term safety and all adverse events (AEs were examined. The efficacy was assessed on the basis of marked improvement (MI and complete remission (CR using a composite efficacy index, which combined global gastrointestinal symptoms and endoscopic assessments.Results: Twenty patients were enrolled in this study; 15 patients received adalimumab treatment until study completion. The incidence of AEs through week 100 was 544.4 events/100 person-years, which was comparable to the incidence through week 52 (560.4 events/100 person-years. No unexpected trend was observed and adalimumab was well tolerated. At weeks 52 and 100, 60.0% and 40.0% of patients showed MI, respectively, and 20.0% and 15.0% of patients showed CR, respectively.Conclusions: This report demonstrates 2 years safety and effectiveness of adalimumab in intestinal BD patients. Patients with intestinal BD refractory to conventional treatment receiving up to 2 years of adalimumab treatment demonstrated safety outcomes consistent with the known profile of adalimumab, and the treatment led to sustained reduction of clinical and endoscopic disease activity.

    Full Text Available Abstract Background Little is known about the clinical features and true survival risk factors in Chinese Han population. We conducted the current study to investigate the clinical features, long-term outcome and true potential indicators associated with mortality of idiopathic inflammatory myopathies (IIM in China. Methods We restrospectvely investigated 188 patients diagnosed with IIM at our hospital from January 1986 to April 2009. The primary outcome was determined with mortality. The secondary outcomes for survival patients were organ damage and disease activity, health status, and disability, which were assessed with Myositis Damage Index, Myositis Disease Activity Assessment Visual Analogue Scales, Health Assessment Questionnaire Disability Index, and the Modified Rankin Scale, respectively. Potential prognostic factors for mortality were analyzed with the multivariate Cox regression model. Results Mean age at disease onset was 43.8 ± 15.8 years and male to female ratio was 1:2.1 in this cohort. The 1-, 5-, 10-, 15- and 20-year survival rates were 93.6%, 88.7%, 81%, 73.6% and 65.6%. The independent predicators for mortality were age at disease onset [hazard ratio (HR:1.05, 95% CI 1.02 - 1.08], presence of cancer (HR:3.68, 95%CI 1.39 - 9.74, and elevated IgA level at diagnosis (HR:2.80, 95% CI 1.16-6.74. At the end of the follow-up, 29 patients manifested drug withdrawal within an average 4.1 years (range 0.5-15.2 year, most patients (85.9% had no disease activity and 130 patients (83.4% had no disability. Conclusions The long-term outcomes of IIM patients in our cohort have improved dramatically. Those patients most likely to survive had a high chance of reaching stable disease status, and obtained long-term or possibly permanent remission to a large extent.

    2011-03-01

    Modern history of short-term group psychotherapy dates back to the late 1950-ies. From then to present day, this psychotherapeutic method has been used in various forms, from dynamic-oriented to cognitive behavioural psychotherapies. Although it has always been considered rather controversial, due its cost-effectiveness, it has been capturing more and more popularity. This paper presents the specificities of first session short-term psychotherapy psychodrama group through session work with two examined groups: a group of 20 adult women who suffer from mild or moderate forms of unipolar depression and a group of 20 students of the School of Medicine in Zagreb without any psychiatric symptomatology. The results indicate the high importance of having structure in first psychodrama session, of relating it with the previously thoroughly conducted, initial, clinical, interviews, and of the clarity and focus in terms of determining the goals of therapy, especially in a clinical context. This study also confirmed assumptions regarding the need for different approaches of warming-up in psychodrama, both in the clinical and in non-clinical samples. A psychodrama psychotherapist should have good time managing skills and capability to convert the time available into an opportunity for directly boosting the group energy and work on therapeutic alliance.

    Full Text Available DNA-abzymes enzymes in autoimmune diseases in clinic and experiment T.E. Naumova, O.M. Durova, A.G. Gabibov, Z.S. Alekberova, S. V. Suchkov DNA-hydrolyzing autoantibodies (AAB or DNA-abzymes can be found in autoimmune diseases in clinic and experiment. Technology of serum express screening for presence of DNA abzymes is described. Comparative study of DNA-hydrolising activity in patients with different forms of systemic and organ-specific autoimmune diseases was performed. Blood of clinically healthy donors was usually free of IgG DNA-abzymes. DNA-abzymes were most often revealed in patients with systemic lupus erythematosus (SLE and rheumatoid arthritis (RA less often in patients with organ-specific forms of autoimmune disturbances. The results of the study confirm the hypothesis of autoimmune origin of IgG DNA abzymes and demonstrate the possibility to use them in clinical practice for monitoring to disease activity in SLE and RA.

    Inflammatory bowel diseases, principally Crohn's disease and ulcerative colitis, and celiac disease are among the most common immune-mediated gastrointestinal diseases. We aim to elucidate the clinical course and outcomes of patients with concomitant inflammatory bowel disease and celiac disease, a unique population that remains scarcely studied to date. A retrospective matched case-control study of adults with coexistent inflammatory bowel disease and celiac disease was performed at a tertiary referral institution in North America. Logistic regression and Kaplan-Meier curves compared disease characteristics and clinical outcomes of the two groups. A total of 342 inflammatory bowel disease patients were included in this study, of which 114 had coexistent celiac disease and 228 did not. Patients with coexistent inflammatory bowel disease and celiac disease had higher rates of primary sclerosing cholangitis (19.3% vs 5.7%; odds ratio, 4.4; 95% confidence interval, 2.1-9.4; pceliac disease (10.5% vs 3.5%; odds ratio 3.2; 95% confidence interval 1.3-8.2; p=0.01), compared to patients without concomitant celiac disease. Patients with inflammatory bowel disease with concomitant celiac disease have unique phenotypic features compared to non-celiac inflammatory bowel disease, with higher risks for colitis-related hospitalizations, extensive colitis, and primary sclerosing cholangitis. Increased recognition of coexistent IBD and celiac disease can prompt clinicians to investigate for concomitant disease sooner, particularly in patients with seemingly refractory disease.

    The diagnosis, treatment, and prevention of infectious diseases in older adults in long-term care facilities (LTCFs), particularly nursing facilities, remains a challenge for all health providers who care for this population. This review provides updated information on the currently most important challenges of infectious diseases in LTCFs. With the increasing prescribing of antibiotics in older adults, particularly in LTCFs, the topic of antibiotic stewardship is presented in this review. Following this discussion, salient points on clinical relevance, clinical presentation, diagnostic approach, therapy, and prevention are discussed for skin and soft tissue infections, infectious diarrhea (Clostridium difficile and norovirus infections), bacterial pneumonia, and urinary tract infection, as well as some of the newer approaches to preventive interventions in the LTCF setting. © 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.

    To assess the clinical usefulness of genetic testing in a pediatric population with inherited retinal disease (IRD). Single-center retrospective case series. Eighty-five unrelated children with a diagnosis of isolated or syndromic IRD who were referred for clinical genetic testing between January 2014 and July 2016. Participants underwent a detailed ophthalmic examination, accompanied by electrodiagnostic testing (EDT) and dysmorphologic assessment where appropriate. Ocular and extraocular features were recorded using Human Phenotype Ontology terms. Subsequently, multigene panel testing (105 or 177 IRD-associated genes) was performed in an accredited diagnostic laboratory, followed by clinical variant interpretation. Diagnostic yield and clinical usefulness of genetic testing. Overall, 78.8% of patients (n = 67) received a probable molecular diagnosis; 7.5% (n = 5) of these had autosomal dominant disease, 25.4% (n = 17) had X-linked disease, and 67.2% (n = 45) had autosomal recessive disease. In a further 5.9% of patients (n = 5), a single heterozygous ABCA4 variant was identified; all these participants had a spectrum of clinical features consistent with ABCA4 retinopathy. Most participants (84.7%; n = 72) had undergone EDT and 81.9% (n = 59) of these patients received a probable molecular diagnosis. The genes most frequently mutated in the present cohort were CACNA1F and ABCA4, accounting for 14.9% (n = 10) and 11.9% (n = 8) of diagnoses respectively. Notably, in many cases, genetic testing helped to distinguish stationary from progressive IRD subtypes and to establish a precise diagnosis in a timely fashion. Multigene panel testing pointed to a molecular diagnosis in 84.7% of children with IRD. The diagnostic yield in the study population was significantly higher compared with that in previously reported unselected IRD cohorts. Approaches similar to the one described herein are expected to become a standard component of care in pediatric ophthalmology

    Abstract Background/aim Clinical risk models are commonly used to predict short‐term coronary artery bypass grafting (CABG) mortality but are less commonly used to predict long‐term mortality. The added value of long‐term mortality clinical risk models over traditional actuarial models has not been evaluated. To address this, the predictive performance of a long‐term clinical risk model was compared with that of an actuarial model to identify the clinical variable(s) most responsible for any differences observed. Methods Long‐term mortality for 1028 CABG patients was estimated using the Hannan New York State clinical risk model and an actuarial model (based on age, gender, and race/ethnicity). Vital status was assessed using the Social Security Death Index. Observed/expected (O/E) ratios were calculated, and the models' predictive performances were compared using a nested c‐index approach. Linear regression analyses identified the subgroup of risk factors driving the differences observed. Results Mortality rates were 3%, 9%, and 17% at one‐, three‐, and five years, respectively (median follow‐up: five years). The clinical risk model provided more accurate predictions. Greater divergence between model estimates occurred with increasing long‐term mortality risk, with baseline renal dysfunction identified as a particularly important driver of these differences. Conclusions Long‐term mortality clinical risk models provide enhanced predictive power compared to actuarial models. Using the Hannan risk model, a patient's long‐term mortality risk can be accurately assessed and subgroups of higher‐risk patients can be identified for enhanced follow‐up care. More research appears warranted to refine long‐term CABG clinical risk models. doi: 10.1111/jocs.12665 (J Card Surg 2016;31:23–30) PMID:26543019

  6. Hematologic manifestations of Crohn's disease: two clinical cases

    2017-01-01

    Full Text Available Inflammatory bowel diseases (IBD are commonly associated with extraintestinal manifestations, hematological disorders being the most special among them. In some cases, they dominate the clinical picture masking the intestinal manifestations of the underlying disease. Aplastic anemia is an extremely rare extraintestinal IBD manifestation. There are only two clinical cases of aplastic anemia associated with ulcerative colitis and non with Crohn's disease reported in the literature. Combination of Crohn's disease and В₁₂-deficient anemia is more prevalent, but is seen usually only after more than 20 cm of the ileus has been resected. The first clinical case presented in this paper is a  combination of severe fistula-forming Crohn's disease with a constriction in the terminal part of the ileus and profound pancytopenia as an outcome of aplastic anemia. This profound pancytopenia is associated with an extremely high risk of life-threatening complications both of surgical treatment, as well as of several chemotherapeutic agents, which made the management of this patient difficult. The second clinical case demonstrates the manifestation of Crohn's disease as ileocolitis starting from the symptoms of cobalamin deficiency: severe В₁₂-deficient anemia, funicular myelosis and sensory ataxia, with blunted intestinal symptoms. This made the initial diagnosis and timely treatment difficult. Replacement therapy with cobalamin injections and treatment with glucocorticoids and antibacterials led to endoscopically confirmed remission of Crohn's disease and normalization of hematological parameters, with persistent polyneuropathy. Thus, management of patients with Crohn's disease should be multidisciplinary. In the case of anemia, leucopenia and/or thrombocytopenia in IBD patients it is necessary to exclude potential myelodysplasia and bone marrow aplasia. In the event of megaloblastic anemia and/or progressive polyneuropathy one should bear in mind

    Niemann-Pick disease type C (NP-C) is a rare, inherited neurodegenerative disease of impaired intracellular lipid trafficking. Clinical symptoms are highly heterogeneous, including neurological, visceral, or psychiatric manifestations. The incidence of NP-C is under-estimated due to under-recognition or misdiagnosis across a wide range of medical fields. New screening and diagnostic methods provide an opportunity to improve detection of unrecognized cases in clinical sub-populations associated with a higher risk of NP-C. Patients in these at-risk groups ("clinical niches") have symptoms that are potentially related to NP-C, but go unrecognized due to other, more prevalent clinical features, and lack of awareness regarding underlying metabolic causes. Twelve potential clinical niches identified by clinical experts were evaluated based on a comprehensive, non-systematic review of literature published to date. Relevant publications were identified by targeted literature searches of EMBASE and PubMed using key search terms specific to each niche. Articles published in English or other European languages up to 2016 were included. Several niches were found to be relevant based on available data: movement disorders (early-onset ataxia and dystonia), organic psychosis, early-onset cholestasis/(hepato)splenomegaly, cases with relevant antenatal findings or fetal abnormalities, and patients affected by family history, consanguinity, and endogamy. Potentially relevant niches requiring further supportive data included: early-onset cognitive decline, frontotemporal dementia, parkinsonism, and chronic inflammatory CNS disease. There was relatively weak evidence to suggest amyotrophic lateral sclerosis or progressive supranuclear gaze palsy as potential niches. Several clinical niches have been identified that harbor patients at increased risk of NP-C.

    Full Text Available Background: Untreated Perthes disease can lead to osteoarthritis by the fourth decade. The treatment is conservative for children 10 years of age at presentation. All patients had limitation of abduction and internal rotation. Eight patients (53.33% had pain at the hip and 12 patients (80% had limp. Mean time between diagnosis and corrective surgery was 3 weeks. Results: The evaluation was done using caput index (CI and epiphyseal quotient (EQ and articulotrochanteric distance radiologically, range of motion and Harris Hip Score for clinical outcome. All the measurements were carried out on pre- and postoperative X-rays after 3 years followup and compared with the contralateral normal hip. After a mean followup period of 3.4 years, we noted the statistically significant difference between pre- and postoperative values. We noted that all (100% children in Stage IB, IIA and 50% children in Stage IIB achieved satisfactory results. There was a significant change (P = 0.000 in CI among all the patients after surgery. The final EQ after 3 years of VDRO was 0.606 and was significant (P = 0.0000. Conclusion: In our opinion, based on the encouraging short term radiological and clinical outcomes, VDRO may be regarded as a treatment procedure for late presenting Perthes disease in stage IB, IIA, IIB.

    We present the results of a clinical and genetic reinvestigation of the Cypriot family affected by an X chromosomally inherited eye disease originally published by Taylor et al, who coined the term Episkopi blindness. The pedigree was extended to 160 members, including 16 affected males out of 48 males at risk for the disease, most of whom were seen by one of us (PA). Affected males are blind with no associated symptoms and apparently are not mentally retarded. Thirty-nine family members agreed to blood sampling for genetic investigations. RFLP analysis was performed using probes from the region known to be deleted in some Norrie patients and polymorphic markers (DXS77, DXS7, MAOA, DXS255) from the proximal short arm of the X chromosome. There was no deletion for any of the probes in the affected males. Linkage analysis yielded positive lod scores for all informative markers (Z (DXS255, theta = 0) = 6.54, Z (MAOA, theta = 0) = 2.23, Z (DXS7, theta = 0) = 2.13). Thus, the conclusion that Episkopi blindness and Norrie disease (NDP, MIM *310600) are the same entity based on clinical evidence is now reinforced by gene mapping.

    Celiac disease is a chronic autoimmune enteropathy caused by gluten ingestion. While its prevalence in Western countries is reported to be as high as 1%, the prevalence has not been evaluated in a large-scale study of a Japanese population. The aim of our study was to clarify the possible presence of celiac disease in a Japanese non-clinical population as well as in patients showing symptoms suggestive of the disease. Serum samples were collected from 2008 non-clinical adults and 47 patients with chronic unexplained abdominal symptoms between April 2014 and June 2016. The anti-tissue transglutaminase (TTG) immunoglobulin A antibody titer was determined as a screening test for celiac disease in all subjects, and individuals with a value of >2 U/mL subsequently underwent testing for the presence of serum endomysial IgA antibody (EMA) as confirmation. Those testing positive for EMA or with a high concentration (>10 U/mL) of TTG were further investigated by histopathological examinations of duodenal mucosal biopsy specimens and HLA typing tests. Of the 2008 non-clinical adults from whom serum samples were collected, 161 tested positive for TTG, and all tested negative for EMA. Four subjects who had a high TTG titer were invited to undergo confirmatory testing, and the histopathological results confirmed the presence of celiac disease in only a single case (0.05%). Of the 47 symptomatic patients, one (2.1%) was found to have a high TTG titer and was diagnosed with celiac disease based on duodenal histopathological findings. The presence of celiac disease in a non-clinical Japanese population was low at 0.05% and was rarely found in patients with unexplained chronic abdominal symptoms.

    PET of the cerebral metabolic rate of glucose is increasingly used to support the clinical diagnosis in the examination of patients with suspected major neurodegenerative disorders, such as Alzheimer's disease. 18 F-FDG PET has been reported to have high diagnostic performance, especially, very high sensitivity in the diagnosis and clinical assessment of therapeutic efficacy. According to clinical research data hitherto, 18 F-FDG PET is expected to be an effective diagnostic tool in early and differential diagnosis of Alzheimer's disease. Since 2004, Medicare covers 18 F-FDG PET scans for the differential diagnosis of fronto-temporal dementia (FTD) and Alzheimer's disease (AD) under specific requirements; or, its use in a CMS approved practical clinical trial focused on the utility of 18 F-FDG PET in the diagnosis or treatment of dementing neurodegenerative diseases

    Full Text Available Cutaneous melanoma is a major concern in terms of healthcare systems and economics. The aim of this study was to estimate the direct costs of melanoma by disease stage, phase of diagnosis, and treatment according to the pre-set clinical guidelines drafted by the AIOM (Italian Medical Oncological Association. Based on the AIOM guidelines for malignant cutaneous melanoma, a highly detailed decision-making model was developed describing the patient’s pathway from diagnosis through the subsequent phases of disease staging, surgical and medical treatment, and follow-up. The model associates each phase potentially involving medical procedures with a likelihood measure and a cost, thus enabling an estimation of the expected costs by disease stage and clinical phase of melanoma diagnosis and treatment according to the clinical guidelines. The mean per-patient cost of the whole melanoma pathway (including one year of follow-up ranged from €149 for stage 0 disease to €66,950 for stage IV disease. The costs relating to each phase of the disease’s diagnosis and treatment depended on disease stage. It is essential to calculate the direct costs of managing malignant cutaneous melanoma according to clinical guidelines in order to estimate the economic burden of this disease and to enable policy-makers to allocate appropriate resources.

  15. Long-term potentiation and long-term depression: a clinical perspective

    Full Text Available Long-term potentiation and long-term depression are enduring changes in synaptic strength, induced by specific patterns of synaptic activity, that have received much attention as cellular models of information storage in the central nervous system. Work in a number of brain regions, from the spinal cord to the cerebral cortex, and in many animal species, ranging from invertebrates to humans, has demonstrated a reliable capacity for chemical synapses to undergo lasting changes in efficacy in response to a variety of induction protocols. In addition to their physiological relevance, long-term potentiation and depression may have important clinical applications. A growing insight into the molecular mechanisms underlying these processes, and technological advances in non-invasive manipulation of brain activity, now puts us at the threshold of harnessing long-term potentiation and depression and other forms of synaptic, cellular and circuit plasticity to manipulate synaptic strength in the human nervous system. Drugs may be used to erase or treat pathological synaptic states and non-invasive stimulation devices may be used to artificially induce synaptic plasticity to ameliorate conditions arising from disrupted synaptic drive. These approaches hold promise for the treatment of a variety of neurological conditions, including neuropathic pain, epilepsy, depression, amblyopia, tinnitus and stroke.

    2011-01-01

    The clinical importance of radiation-induced heart disease, in particular in post-operative radiotherapy of breast cancer patients, has been recognised only recently. There is general agreement, that a co-ordinated research effort would be needed to explore all the potential strategies of how to reduce the late risk of radiation-induced heart disease in radiotherapy. This approach would be based, on one hand, on a comprehensive understanding of the radiobiological mechanisms of radiation-induced heart disease after radiotherapy which would require large-scale long-term animal experiments with high precision local heart irradiation. On the other hand - in close co-operation with mechanistic in vivo research studies - clinical studies in patients need to determine the influence of dose distribution in the heart on the risk of radiation-induced heart disease. The aim of these clinical studies would be to identify the critical structures within the organ which need to be spared and their radiation sensitivity as well as a potential volume and dose effect. The results of the mechanistic studies might also provide concepts of how to modify the gradual progression of radiation damage in the heart by drugs or biological molecules. The results of the studies in patients would need to also incorporate detailed dosimetric and imaging studies in order to develop early indicators of impending radiation-induced heart disease which would be a pre-condition to develop sound criteria for treatment plan optimisation.

  17. Motor outcome measures in Huntington disease clinical trials.

    2017-01-01

    Deficits in motor function are a hallmark of Huntington disease (HD). The Unified Huntington's Disease Rating Scale Total Motor Score (UHDRS-TMS) is a categoric clinical rating scale assessing multiple domains of motor disability in HD. The UHDRS-TMS or subsets of its items have served as primary or secondary endpoints in numerous clinical trials. In spite of a well-established video-based annual online certification system, intra- and interrater variability, subjective error, and rater-induced placebo effects remain a concern. In addition, the UHDRS-TMS was designed to primarily assess motor symptoms in manifest HD. Recently, advancement of technology resulted in the introduction of the objective Q-Motor (i.e., Quantitative-Motor) assessments in biomarker studies and clinical trials in HD. Q-Motor measures detected motor signs in blinded cross-sectional and longitudinal analyses of manifest, prodromal, and premanifest HD cohorts up to two decades before clinical diagnosis. In a multicenter clinical trial in HD, Q-Motor measures were more sensitive than the UHDRS-TMS and exhibited no placebo effects. Thus, Q-Motor measures are currently explored in several multicenter trials targeting both symptomatic and disease-modifying mechanisms. They may supplement the UHDRS-TMS, increase the sensitivity and reliability in proof-of-concept studies, and open the door for phenotype assessments in clinical trials in prodromal and premanifest HD.

RESULTS: There were 23 patients(35 eyeswith orbit IgG4-RD(8 male patients, 9 eyes; 15 female patients, 26 eyes, with an average age of 52.1 year-old(from age 28 to 72. 19 patients(30 eyesoccured in lacrimal gland and 4 cases(5 eyesin other places, and they went to hospital for lacrimal gland cyst or exophthalmos. There were 11 cases in one side and 12 cases in both sides. The disease lasted from 1mo to 10a, averaging 27mo. It recureded in one patient(1 eyeafter 1mo. In general inspection: Gray nodular goiter, thin fibrous coat wrapping around the lacrimal gland could be observed. Histologic characteristics: lacrimal gland bubble and catheter group shrinked or even disappeared, substituted by lymphocyte, plasma cells and lymphoid follicle and accompanied with fibrosis. Immunohistochemical staining: IgG4 positive plasma cells of 23 cases(35 eyeswas >50/HPF, and IgG4/IgG ratio of positive plasma cells was >40%. CONCLUSION: Orbit IgG4-RD mainly occures in lacrimal gland tissue, and expression of IgG4 can be detected through histologic characteristics and immunohistochemical staining. IgG4-RD should be screened, prevented and treated in the early phase.

  1. Contemporary Reflections on the Safety of Long-Term Aspirin Treatment for the Secondary Prevention of Cardiovascular Disease

    Fanaroff, Alexander C.; Roe, Matthew T.

    2018-01-01

    Aspirin has been the cornerstone of therapy for the secondary prevention treatment of patients with cardiovascular disease since landmark trials were completed in the late 1970s and early 1980s that demonstrated the efficacy of aspirin for reducing the risk of ischemic events. Notwithstanding the consistent benefits demonstrated with apirin for both acute and chronic cardiovascular disease, there are a number of toxicities associated with aspirin that have been showcased by recent long-term clinical trials that have included an aspirin monotherapy arm. As an inhibitor of cyclooxygenase, aspirin impairs gastric mucosal protective mechanisms. Prior trials have shown that up to 15–20% of patients developed gastrointestinal symptoms with aspirin monotherapy and roughly 1% of patients per year had a clinically significant bleeding event, including 1 in 1000 patients who suffered an intracranial or fatal bleed. These risks have been shown to be compounded for patients with acute coronary syndromes (ACS) and those undergoing percutaneous coronary intervention (PCI), who are also treated with other anti-thrombotic agents during the acute care/procedural period, as well as for an extended time period afterwards. Given observations of substantial increases in bleeding rates from many prior long-term clinical trials that have evaluated aspirin together with other oral platelet inhibitors or oral anti-coagulants, the focus of contemporary research has pivoted towards tailored anti-thrombotic regimens that attempt to either shorten the duration of exposure to aspirin or replace aspirin with an alternative anti-thrombotic agent. While these shifts are occurring, the safety profile of aspirin when used for the secondary prevention treatment of patients with established cardiovascular disease deserves further consideration.

    Full Text Available Umamon Puangthong, Ging-Yuek Robin HsiungDivision of Neurology, Department of Medicine, University of British Columbia, Vancouver, BC, CanadaAbstract: Alzheimer’s disease is the most common cause of dementia in older adults. The clinical features include progressive memory decline as well as cognitive deficits with executive dysfunction, language, visual perceptual difficulties, apraxia and agnosia. During the moderate to severe stage of the disease, there is a major decline in memory and function, while neuropsychiatric disturbances often emerge and patients become difficult to manage. These distressing symptoms increase caregiver burden and add to the direct costs of care of the patients. Any improvements in patient function and behavioral symptoms can reduce caregiver burden. Memantine has been available for a number of years in Europe and in North America. In this article, we examine the pharmacological rationale for its use, and the current clinical evidence for its efficacy and long-term effectiveness in the management of cognitive and behavioral symptoms in moderate to severe stages of Alzheimer’s disease.Keywords: memantine, Alzheimer’s disease, dementia

    Background: The problem of incomplete myocardial revascularization for diffuse and distal lesions of the myocardium is still relevant. We assessed the clinical and instrumental long-term results of autologous bone marrow cell (BMC) implantation in laser channels in ischemic heart disease with diffuse and distal coronary disease. 35 coronary heart disease (CHD) patients with diffuse and distal coronary disease during coronary artery bypass grafting (CABG) underwent BMC implantation in laser channels. The control group consisted of 29 patients. All patients in this group underwent only CABG. Clinical and instrumental assessment of the method's effect was carried out at two weeks, six months, and six years after surgery. Indirect revascularization showed more significant decreasing of the functional class (FC) New York Heart Association (NYHA), myocardial perfusion and contractility improvement. Autologous BMC implantation in laser channels is an effective method of CHD surgical treatment if it is impossible to perform direct myocardial revascularization. The indirect revascularization effect is formed in the first six months after surgery and remains at the same level for six years.

    The purpose of this study to develop new deep-brain stimulation system for long-term use in animals, in order to develop a variety of neural prostheses. Our system has two distinguished features, which are the fully implanted system having wearable wireless power transfer and ability to change the parameter of stimulus parameter. It is useful for obtaining a variety of data from a long-term experiment. To validate our system, we performed pre-clinical test in Parkinson's disease-rat models for 4 weeks. Through the in vivo test, we observed the possibility of not only long-term implantation and stability, but also free movement of animals. We confirmed that the electrical stimulation neither caused any side effect nor damaged the electrodes. We proved possibility of our system to conduct the long-term pre-clinical test in variety of parameter, which is available for development of neural prostheses.

    Refractory coeliac disease (RCD) is thought to be a rare disorder, but the accurate prevalence is unknown. We aimed to identify the prevalence of and the risk factors for developing RCD in a Finnish population where the clinical detection rate of coeliac disease is high. The study involved 11 hospital districts in Finland where the number of treated RCD patients (n = 44), clinically diagnosed coeliac disease patients (n = 12 243) and adult inhabitants (n = 1.7 million) was known. Clinical characteristics at diagnosis of coeliac disease between the RCD patients and patients with uncomplicated disease were compared. The prevalence of RCD was 0.31% among diagnosed coeliac disease patients and 0.002% in the general population. Of the enrolled 44 RCD patients, 68% had type I and 23% type II; in 9% the type was undetermined. Comparing 886 patients with uncomplicated coeliac disease with these 44 patients that developed RCD later in life, the latter were significantly older (median 56 vs 44 years, P coeliac disease. Patients with evolving RCD had more severe symptoms at the diagnosis of coeliac disease, including weight loss in 36% (vs. 16%, P = 0.001) and diarrhoea in 54% (vs. 38%, P = 0.050). Refractory coeliac disease is very rare in the general population. Patients of male gender, older age, severe symptoms or seronegativity at the diagnosis of coeliac disease are at risk of future refractory coeliac disease and should be followed up carefully. © 2014 John Wiley & Sons Ltd.

    The clinical features, pathology, and immunopathology of chronic graft-versus-host disease (GVHD) developing in the long-term rat radiation chimera are described. At 6 to 12 months post-transplant, the previously stable ACI/LEW chimeras developed patchy to diffuse severe hair loss and thickened skin folds, and had microscopic features resembling scleroderma, Sjogren's syndrome, and chronic hepatitis. Skin histology showed dermal inflammation and acanthosis with atrophy of the appendages, with progression to dermal sclerosis. The liver revealed chronic hepatitis with bile duct injury and proliferation and periportal piecemeal necrosis. The tongue had considerable submucosal inflammation, muscular necrosis, and atrophy and arteritis. The serous salivary glands, lacrimal glands, and bronchi had lymphocytic inflammation and injury to duct, acinar, and mucosal columnar epithelium. The thymus had lymphocyte depletion of the medulla with prominent epithelium. The spleen and lymph nodes had poorly developed germinal centers but increased numbers of plasma cells. IgM was observed along the basement membrane and around the basal cells of the skin and tongue and along the basement membrane of the bile ducts. IgM was present also in the arteries of the tongue. Immunoglobulins eluted from the skin, cross-reacted with the bile duct epithelium and usually with both ACI and Lewis skin. Increased titers of speckled antinuclear antibodies were present in the serum of rats with chronic (GVHD). Chronic GVHD in the long-term rat radiation chimera is very similar to human chronic GVHD and is a potentially excellent model for autoimmune disorders including scleroderma, Sjorgren's syndrome, and chronic hepatitis.

    Full Text Available From 1981 to 1991, 55 patients (33 males, 22 females, mean age 58.6 years with nosocomial Legionnaires’ disease were studied. The mortality rate was 64%. One-half of the patients developed nosocomial Legionnaires’ disease within three weeks of admission. A surprising clinical feature was the low rate of findings of consolidation on physical examination, despite the fact that 52% of patients had this finding on chest radiograph. More than one-half of patients had pre-existing lung disease, rendering a radiographic diagnosis of pneumonia due to Legionella pneumophila impossible in 16% of cases despite microbiological confirmation. Nineteen per cent of patients who had blood cultures done had a pathogen other than L pneumophila isolated, suggesting dual infection in at least some of the patients. When the clinical and radiographic findings were combined it was noted that 40% of patients had one of three patterns suggestive of nosocomial Legionnaires’ disease: rapidly progressive pneumonia, lobar opacity and multiple peripheral opacities. However, in 60% of patients there were no distinctive features.

    Adrenal computed tomographic (CT) scanning was conducted in twelve patients with Addison's disease during the clinical course. In tuberculous Addison's disease (n=8), three of four patients examined during the first two years after disease onset had bilaterally enlarged adrenals, while one of four had a unilaterally enlarged one. At least one adrenal gland was enlarged after onset in all six patients examined during the first four years. Thereafter, the adrenal glands was atrophied bilaterally, in contrast to adrenal glands in idiopathic Addison's disease which was atrophied bilaterally from disease onset (n=2). Adrenal calcification was a less sensitive clue in tracing pathogenesis, i.e., adrenal calcification was observed in five of eight patients with tuberculous Addison's disease, but not idiopathic patients. Thus, adrenal CT scanning could show the etiology of Addison's disease (infection or autoimmunity) and the phase of Addison's disease secondary to tuberculosis, which may be clinically important for initiating antituberculous treatment.

Given the incomplete response of many patients to a GFD-free diet as well as the difficulty of adherence to the GFD over the long term, development of new effective therapies for symptom control and reversal of inflammation and organ damage are needed. The prevalence of celiac disease is increasing worldwide and many patients with celiac disease remain undiagnosed, highlighting the need for improved strategies in the future for the optimal detection of patients.

    Full Text Available Severe liver diseases such as liver failure and acute decompensated cirrhosis have critical conditions and high mortality rates, and the prognosis of such patients is closely associated with early warning, timely dynamic assessment, and comprehensive and effective therapy. The patients require a series of effective clinical management measures for elimination of causative factors, organ support, and prevention and treatment of complications. Medical treatment-artificial liver-liver transplantation is an important modality for severe liver diseases. Granulocyte colony-stimulating factor, stem cell therapy, and bioartificial liver have a promising future, while there are still controversies over non-selective β-blocker.

    Full Text Available A 51-year-old man was referred for body weight loss and lower right abdominal pain. Total colonoscopy revealed discrete and round ulceration at the ileocecal valve, and he was diagnosed with intestinal Behçet's disease (BD. By treatment with glucocorticoid, colchicine and salazosulfapyridine, the symptoms and ulceration were improved, but cessation of glucocorticoid resulted in relapse of ulceration at the terminal ileum. Long-term, low-dose treatment with clarithromycin (CAM was implemented for chronic respiratory infections. Furthermore, we expected that this CAM treatment would also be effective in BD. During this long-term, low-dose treatment with CAM, discrete ulceration at the terminal ileum was never revealed by follow-up total colonoscopy once or twice per year for 7 years. No reports have described the effectiveness of this treatment in patients with intestinal BD; however, we confirm that long-term treatment with low-dose CAM might have clinical benefits for patients with intestinal BD.

    Meningococcal disease is the acute infection caused by Neisseria meningitidis, which has humans as the only natural host. The disease is widespread around the globe and is known for its epidemical potential and high rates of lethality and morbidity. The highest number of cases of the disease is registered in the semi-arid regions of sub-Saharan Africa. In Brazil, it is endemic with occasional outbreaks, epidemics and sporadic cases occurring throughout the year, especially in the winter. The major epidemics of the disease occurred in Brazil in the 70's caused by serogroups A and C. Serogroups B, C and Y represent the majority of cases in Europe, the Americas and Australia. However, there has been a growing increase in serogroup W in some areas. The pathogen transmission happens for respiratory route (droplets) and clinically can lead to meningitis and sepsis (meningococcemia). The treatment is made with antimicrobial and supportive care. For successful prevention, we have some measures like vaccination, chemoprophylaxis and droplets' precautions. In this review, we have described and clarify clinical features of the disease caused by N. meningitidis regarding its relevance for healthcare professionals.

    Decompression and fusion is considered as the 'gold standard' for the treatment of degenerative lumbar diseases, however, many disadvantages have been reported in several studies, recently like donor site pain, pseudoarthrosis, nonunion, screw loosening, instrumentation failure, infection, adjacent segment disease (ASDis) and degeneration. Dynamic neutralization system (Dynesys) avoids many of these disadvantages. This system is made up of pedicle screws, polyethylene terephthalate cords, and polycarbonate urethane spacers to stabilize the functional spinal unit and preserve the adjacent motion after surgeries. This was a retrospective cohort study to compare the effect of Dynesys for treating degenerative lumbar diseases with posterior lumbar interbody fusion (PLIF) based on short term followup. Seventy five consecutive patients of lumbar degenerative disease operated between October 2010 and November 2012 were studied with a minimum followup of 2 years. Patients were divided into two groups according to the different surgeries. 30 patients underwent decompression and implantation of Dynesys in two levels (n = 29) or three levels (n = 1) and 45 patients underwent PLIF in two levels (n = 39) or three levels (n = 6). Clinical and radiographic outcomes between two groups were reviewed. Thirty patients (male:17, female:13) with a mean age of 55.96 ± 7.68 years were included in Dynesys group and the PLIF group included 45 patients (male:21, female:24) with a mean age of 54.69 ± 3.26 years. The average followup in Dynesys group and PLIF group was 2.22 ± 0.43 year (range 2-3.5 year) and 2.17 ± 0.76 year (range 2-3 year), respectively. Dynesys group showed a shorter operation time (141.06 ± 11.36 min vs. 176.98 ± 6.72 min, P degenerative disease showed clinical benefits with motion preservation of the operated segments, but does not have the significant advantage on motion preservation at adjacent segments, to avoid the degeneration of adjacent intervertebral disk.

  1. Autoimmune Subepidermal Bullous Diseases of the Skin and Mucosae: Clinical Features, Diagnosis, and Management.

    Autoimmune subepidermal blistering diseases of the skin and mucosae constitute a large group of sometimes devastating diseases, encompassing bullous pemphigoid, gestational pemphigoid, mucous membrane pemphigoid, epidermolysis bullosa acquisita, and anti-p200 pemphigoid. Their clinical presentation is polymorphic. These autoimmune blistering diseases are associated with autoantibodies that target distinct components of the basement membrane zone of stratified epithelia. These autoantigens represent structural proteins important for maintenance of dermo-epidermal integrity. Bullous pemphigoid (BP) is the most common subepidermal autoimmune blistering disease of the skin and mucosae. Although the disease typically presents with a generalized blistering eruption associated with itch, atypical variants with either localized bullous lesions or "non-bullous" presentations are observed in approximately 20% of patients. A peculiar form of BP typically associated with pregnancy is pemphigoid gestationis. In anti-p200 pemphigoid, patients present with tense blisters on erythematosus or normal skin resembling BP, with a predilection for acral surfaces. These patients have antibodies targeting the 200-kDa basement membrane protein. Epidermolysis bullosa is a rare autoimmune blistering disease associated with autoantibodies against type VII collagen that can have several phenotypes including a classical form mimicking dystrophic epidermolysis bullosa, an inflammatory presentation mimicking BP, or mucous membrane pemphigoid-like lesions. Mucous membrane pemphigoid (MMP) is the term agreed upon by international consensus for an autoimmune blistering disorder, which affects one or more mucous membrane and may involve the skin. The condition involves a number of different autoantigens in the basement membrane zone. It may result in severe complications from scarring, such as blindness and strictures. Diagnosis of these diseases relies on direct immunofluorescence microscopy studies

    Full Text Available Abstract Huntington disease (HD is a rare neurodegenerative disorder of the central nervous system characterized by unwanted choreatic movements, behavioral and psychiatric disturbances and dementia. Prevalence in the Caucasian population is estimated at 1/10,000-1/20,000. Mean age at onset of symptoms is 30-50 years. In some cases symptoms start before the age of 20 years with behavior disturbances and learning difficulties at school (Juvenile Huntington's disease; JHD. The classic sign is chorea that gradually spreads to all muscles. All psychomotor processes become severely retarded. Patients experience psychiatric symptoms and cognitive decline. HD is an autosomal dominant inherited disease caused by an elongated CAG repeat (36 repeats or more on the short arm of chromosome 4p16.3 in the Huntingtine gene. The longer the CAG repeat, the earlier the onset of disease. In cases of JHD the repeat often exceeds 55. Diagnosis is based on clinical symptoms and signs in an individual with a parent with proven HD, and is confirmed by DNA determination. Pre-manifest diagnosis should only be performed by multidisciplinary teams in healthy at-risk adult individuals who want to know whether they carry the mutation or not. Differential diagnoses include other causes of chorea including general internal disorders or iatrogenic disorders. Phenocopies (clinically diagnosed cases of HD without the genetic mutation are observed. Prenatal diagnosis is possible by chorionic villus sampling or amniocentesis. Preimplantation diagnosis with in vitro fertilization is offered in several countries. There is no cure. Management should be multidisciplinary and is based on treating symptoms with a view to improving quality of life. Chorea is treated with dopamine receptor blocking or depleting agents. Medication and non-medical care for depression and aggressive behavior may be required. The progression of the disease leads to a complete dependency in daily life, which

    were 5 cohort studies, 2 prospective and 3 retrospective. The two prospective studies did not show an increased risk of all-cause mortality in subjects with asymptomatic celiac disease. Grading of Evidence The quality of the evidence for each serologic tests evaluated based on the GRADE Working Group criteria. Overall, the quality of the evidence ranged from low to very low depending on the outcome evaluated. The Clinical Utility of Serologic Testing for Celiac Disease in Asymptomatic Subjects Eligible studies that evaluated the effects of a GFD on disease-specific outcomes were only identified for two of the conditions evaluated, type 1 diabetes and idiopathic short stature. The clinical utility of serologic testing for celiac disease in patients with type 1 diabetes without symptoms consistent with celiac disease was not demonstrated since the studies identified did not provide evidence of the impact of the GFD on either metabolic control or long-term outcomes in these patients. The clinical utility of serologic testing for celiac disease in patients with idiopathic short stature without symptoms consistent with celiac disease was demonstrated since the studies identified showed an acceleration in growth once the diagnosis of celiac disease was made and a GFD was introduced. The Budget Impact of Serologic Testing for Celiac Disease in Asymptomatic Patients The budget impact of serologic testing for celiac disease in asymptomatic patients was calculated for the conditions for which clinical utility for serologic testing was demonstrated. The budget impact in patients with idiopathic short stature without symptoms consistent with celiac disease was estimated as C$552,000 as calculated by multiplying the number of individuals in Ontario with idiopathic short stature that may be eligible for the test by the cost of the serologic test for celiac disease. Conclusions Based on a review of the literature, there is an increased risk of asymptomatic celiac disease in patients

    Background  Coronary heart disease is the major cause of illness and death in Western countries and this is likely to increase as the average age of the population rises. Consumers with established coronary heart disease are at the highest risk of experiencing further coronary events. Lifestyle measures can contribute significantly to a reduction in cardiovascular mortality in established coronary heart disease. Improved management of cardiac risk factors by providing education and referrals as required has been suggested as one way of maintaining quality care in patients with established coronary heart disease. There is a need to ascertain whether or not nurse-led clinics would be an effective adjunct for patients with coronary heart disease to supplement general practitioner advice and care. Objectives  The objective of this review was to present the best available evidence related to nurse-led cardiac clinics. Inclusion criteria  This review considered any randomised controlled trials that evaluated cardiac nurse-led clinics. In the absence of randomised controlled trials, other research designs such as non-randomised controlled trials and before and after studies were considered for inclusion. Participants were adults (18 years and older) with new or existing coronary heart disease. The interventions of interest to the review included education, assessment, consultation, referral and administrative structures. Outcomes measured included adverse event rates, readmissions, admissions, clinical and cost effectiveness, consumer satisfaction and compliance with therapy. Results  Based on the search terms used, 80 papers were initially identified and reviewed for inclusion; full reports of 24 of these papers were retrieved. There were no papers included that addressed cost effectiveness or adverse events; and none addressed the outcome of referrals. A critical appraisal of the 24 remaining papers identified a total of six randomised controlled trials that

    The application of stem cell transplants in clinical practice has increased in frequency in recent years. Many of the stem cell transplants in neurologic diseases, including stroke, Parkinson disease, spinal cord injury, and demyelinating diseases, are unproven-they have not been tested...... in prospective, controlled clinical trials and have not become accepted therapies. Stem cell transplant procedures currently being carried out have therapeutic aims, but are frequently experimental and unregulated, and could potentially put patients at risk. In some cases, patients undergoing such operations...... are not included in a clinical trial, and do not provide genuinely informed consent. For these reasons and others, some current stem cell interventions for neurologic diseases are ethically dubious and could jeopardize progress in the field. We provide discussion points for the evaluation of new stem cell...

    Due to the growing global health impact of Alzheimer's disease (AD), there is a greater need for interventions that prevent or delay the onset of clinical symptoms of this debilitating disease. Clinical trials for disease-modifying compounds in AD have shifted towards earlier stages in the spectrum of illness, including the stage prior to cognitive symptoms. A population of specific interest for clinical research includes individuals with evidence of Alzheimer's disease pathology who are asymptomatic (ADPa). The challenges and barriers regarding medical treatment of ADPa must be identified and addressed prior to the completion of a positive clinical trial in order to accelerate the translation of research findings to clinical practice. This report applies an existing public health impact model from Spencer and colleagues (2013) to evaluate the readiness of the clinical practice environment to treat ADPa individuals if a disease-modifying agent achieves approval. We contrast the current clinical practice environment with a potential future state through investigating the effectiveness, reach, feasibility, sustainability, and transferability of the practice of treating ADPa individuals.

    The present review aims to ascertain whether different infertility etiologies share particular genes and/or molecular pathways with other pathologies and are associated with distinct and particular risks of later-life morbidity and mortality. In order to reach this aim, we use two different sources of information: (1) a public web server named DiseaseConnect ( http://disease-connect.org ) focused on the analysis of common genes and molecular mechanisms shared by diseases by integrating comprehensive omics and literature data; and (2) a literature search directed to find clinical comorbid relationships of infertility etiologies with only those diseases appearing after infertility is manifested. This literature search is performed because DiseaseConnect web server does not discriminate between pathologies emerging before, concomitantly or after infertility is manifested. Data show that different infertility etiologies not only share particular genes and/or molecular pathways with other pathologies but they have distinct clinical relationships with other diseases appearing after infertility is manifested. In particular, (1) testicular and high-grade prostate cancer in male infertility; (2) non-fatal stroke and endometrial cancer, and likely non-fatal coronary heart disease and ovarian cancer in polycystic ovary syndrome; (3) osteoporosis, psychosexual dysfunction, mood disorders and dementia in premature ovarian failure; (4) breast and ovarian cancer in carriers of BRCA1/2 mutations in diminished ovarian reserve; (5) clear cell and endometrioid histologic subtypes of invasive ovarian cancer, and likely low-grade serous invasive ovarian cancer, melanoma and non-Hodgkin lymphoma in endometriosis; and (6) endometrial and ovarian cancer in idiopathic infertility. The present data endorse the principle that the occurrence of a disease (in our case infertility) is non-random in the population and suggest that different infertility etiologies are genetically and clinically

    2016-05-01

    Lyme disease (Lyme borreliosis) is a systemic infectious disease that can present in a variety of clinical manifestations. The disease is caused by a group of spirochaetes--Borrelia burgdorferi sensu lato or Lyme borrelia--that are transmitted to humans by the bite of Ixodes ticks. Lyme disease is the most common arthropode-borne infectious disease in many European countries including Germany. Early localized infection is typically manifested by an erythema migrans skin lesion, in rarer cases as a borrelial lymphocytoma. The most common early disseminated manifestation is (early) neuroborreliosis. In adults, neuroborreliosis appears typically as meningoradiculoneuritis. Neuroborreliosis in children, however, is typically manifested by meningitis. In addition, multiple erythema migrans lesions and Lyme carditis occur relatively frequently. The most common manifestation oflate Lyme disease is Lyme arthritis. Early manifestations (and usually also late manifestations) of Lyme disease can be treated successfully by application of suitable antibacterial agents. For the treatment of Lyme disease, doxycycline, certain penicillins such as amoxicillin and some cephalosporins (ceftriaxone, cefotaxime, cefuroxime axetil) are recommended in current guidelines. A major challenge is the treatment of chronic, non-specific disorders, i. e., posttreatment Lyme disease syndrome and "chronic Lyme disease". Prevention of Lyme disease is mainly accomplished by protecting against tick bites. Prophylactic administration of doxycycline after tick bites is generally not recommended in Germany. There is no vaccine available for human beings.

    Full Text Available Abstract Background Neglected tropical diseases are widespread, particularly in sub-Saharan Africa, affecting over 2 billion individuals. Control of these diseases has gathered pace in recent years, with increased levels of funding from a number of governmental or non-governmental donors. Focus has currently been on five major 'tool-ready' neglected tropical diseases (lymphatic filariasis, onchocerciasis, schistosomiasis, soil-transmitted helminthiasis and trachoma, using a package of integrated drug delivery according to the World Health Organization guidelines for preventive chemotherapy. Discussion Success in controlling these neglected tropical diseases has been achieved in a number of countries in recent history. Experience from these successes suggests that long-term sustainable control of these diseases requires: (1 a long-term commitment from a wider range of donors and from governments of endemic countries; (2 close partnerships of donors, World Health Organization, pharmaceutical industries, governments of endemic countries, communities, and non-governmental developmental organisations; (3 concerted action from more donor countries to provide the necessary funds, and from the endemic countries to work together to prevent cross-border disease transmission; (4 comprehensive control measures for certain diseases; and (5 strengthened primary healthcare systems as platforms for the national control programmes and capacity building through implementation of the programmes. Conclusions The current level of funding for the control of neglected tropical diseases has never been seen before, but it is still not enough to scale up to the 2 billion people in all endemic countries. While more donors are sought, the stakeholders must work in a coordinated and harmonised way to identify the priority areas and the best delivery approaches to use the current funds to the maximum effect. Case management and other necessary control measures should be

    Most peripheral artery disease (PAD) clinical device trials are supported by commercial manufacturers and designed for regulatory device approval, with extensive inclusion/exclusion criteria to support homogeneous patient populations. High-risk patients with advanced disease, including critical limb ischemia (CLI), are often excluded leading to difficulty in translating trial results into real-world clinical practice. As a result, physicians have no direct guidance regarding the use of endovascular devices. There is a need for objectively assessed studies to evaluate clinical, functional, and economic outcomes in PAD patient populations. LIBERTY is a prospective, observational, multicenter study sponsored by Cardiovascular Systems Inc (St Paul, MN) to evaluate procedural and long-term clinical and economic outcomes of endovascular device interventions in patients with symptomatic lower extremity PAD. Approximately 1,200 patients will be enrolled and followed up to 5 years: 500 patients in the "Claudicant Rutherford 2-3" arm, 600 in the "CLI Rutherford 4-5" arm, and 100 in the "CLI Rutherford 6" arm. The study will use 4 core laboratories for independent analysis and will evaluate the following: procedural and lesion success, rates of major adverse events, duplex ultrasound interpretations, wound status, quality of life, 6-minute walk test, and economic analysis. The LIBERTY Patient Risk Score(s) will be developed as a clinical predictor of outcomes to provide guidance for interventions in this patient population. LIBERTY will investigate real-world PAD patients treated with endovascular revascularization with rigorous study guidelines and independent oversight of outcomes. This study will provide observational, all-comer patient clinical data to guide future endovascular therapy. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

Methods Alzheimer's disease, donepezil, rivastigmine, galantamine, memantine, rosiglitazone, etc. were defined as retrieval words. PubMed, Cochrane Library, Wanfang Data and China National Knowledge Infrastructure (CNKI databases were used with applying of manual searching. Systematic reviews, randomized controlled trials (RCT, controlled clinical trials and case-observation studies were collected and evaluated by Jadad Scale. Results After screening, 33 selected resources included 14 systematic reviews, 14 randomized controlled trials, 4 controlled clinical trials and 1 case-observation study. According to Jadad Scale, total 28 articles were evaluated to be high quality (12 with score 4, 10 score 5, 6 score 7, and 5 were low quality with score 3. It was summarized as follows: 1 Alzheimer's disease is a progressive neurodegenerative disease for which no cure exists. To date, only symptomatic treatments with cholinesterase inhibitors (donepezil, rivastigmine, galantamine and an N-methyl-D-aspartate (NMDA receptor noncompetitive antagonist (memantine, are effective and well tolerated to counterbalance the neurotransmitter disturbance, but cannot limit or impact on disease progression. 2 Disease modifying drug is an potential agent, with persistent effect on slowing the progression of structural damage, and can be detected even after withdrawing the treatment. Many types of disease modifying drugs are undergoing clinical trials. Conclusions Using evidence-based medicine methods can provide best clinical evidence on Alzheimer's disease treatment. doi: 10.3969/j.issn.1672-6731.2014.03.009

    Wilson's disease of cerebral type with a chief complaint of tremor occurred in 3 brothers and sisters of a certain family line. Treatment with D-penicillamine produced remarkable clinical improvement as shown by the disappearance of tremor and Kayser-Fleischer ring. Cranial CT scans made before the treatment revealed abnormal findings such as low density areas in the (bilateral) thalamus and the lenticular nucleus, atrophy of the cerebral cortex, and enlargement of the ventricles. After the treatment, cranial CT revealed that the low density areas in the thalamus and the lenticular nucleus disappeared corresponding to the clinical improvement. However, the atrophy of the cerebral cortex and the enlargement of the ventricles were not ameliorated. (Ueda, J.)

    Pharmacogenetics has become extremely important over the last 20 years for identifying individuals more likely to be responsive to pharmacological interventions. The role of genetic background as a predictor of drug response is a young and mostly unexplored field in neurodegenerative diseases. Mendelian mutations in neurodegenerative diseases have been used as models for early diagnosis and intervention. On the other hand, genetic polymorphisms or risk factors for late-onset Alzheimer's disease (AD) or other neurodegenerative diseases, probably influencing drug response, are hardly taken into account in randomized clinical trial (RCT) design. The same is true for genetic variants in cytochrome P450 (CYP), the principal enzymes influencing drug metabolism. A better characterization of individual genetic background may optimize clinical trial design and personal drug response. This chapter describes the state of the art about the impact of genetic factors in RCTs on neurodegenerative disease, with AD, frontotemporal dementia, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease as examples. Furthermore, a brief description of the genetic bases of drug response focusing on neurodegenerative diseases will be conducted. The role of pharmacogenetics in RCTs for neurodegenerative diseases is still a young, unexplored, and promising field. Genetic tools allow increased sophistication in patient profiling and treatment optimization. Pharmaceutical companies are aware of the value of collecting genetic data during their RCTs. Pharmacogenetic research is bidirectional with RCTs: efficacy data are correlated with genetic polymorphisms, which in turn define subjects for treatment stratification. © 2016 S. Karger AG, Basel.

    Full Text Available Protonic pump inhibitors (PPIs are the most prescribed drugs for acute and maintenance therapy of gastroesophageal reflux disease, H. pylori-eradication (in association with antibacterial therapy, for ulcers prevention and cure and, recently, for prevention of NSAIDs-induced gastropathy. The high prevalence of these acid-related disorders induces a large consumption of PPIs; actually, they are the first drug class in terms of National Health Service pharmaceutical expenditure. This widespread and gradually increasing use enforces the need of a rational assessment of their impact on health care resources. This paper provides an updated profile of esomeprazole, the first PPI developed as a pure isomer, which property involves an advantageous metabolism, resulting in enhanced delivery to the proton pump compared with racemic omeprazole. Several studies showed that the success rate for healing reflux esophagitis is greater for esomeprazole than for omeprazole and some other PPIs. According to an Italian pharmacoeconomic model, esomeprazole therapy for erosive esophagitis is associated with higher benefits and lower costs as compared to omeprazole and pantoprazole. For long-term management of non-erosive gastroesophageal reflux disease, on-demand approach with esomeprazole shows clinical outcomes similar to daily treatment regimens, with substantial cost-saving. Furthermore, esomeprazole is the only PPI approved for 1-week triple therapy for both the eradication and the healing of H. pylori-associated duodenal ulcer, while the other PPIs registered the indication for H. pylori-eradication and, separately, a dosing scheme for ulcer healing (independently from etiology.

    Koleva, Yordanka Nikolova

    Chronic diseases are increasingly recognized as major contributors to the global burden of disease. Individuals with chronic disease are particularly vulnerable during mass emergencies as they may suffer an interruption in their therapeutic programs, leading to life-threatening conditions and complications. Based on the individual and community risk factors framework, three categories are defined as the most vulnerable to extreme natural events: physically, psychologically, and socially vulnerable. Complex emergencies that occurred in the recent decade have provided evidence that these groups suffer more pronounced effects than others. Individuals seeking community support during emergencies have been predominantly medically dependent, elderly, children, people with chronic health conditions, and lower socioeconomic status. The purpose of this study was to investigate the effect of health-related vulnerability on shelter operations, and to estimate the burden of chronic disease on community resources following catastrophic events. A comprehensive survey data collection conducted by the United States Public Health Service in 2005 was used to evaluate clinical services for populations with health conditions accommodated by Louisiana temporary disaster shelters. Correlation and multiple regression analyses determined the relationship between shelter characteristics and the factors predicting shelters' needs for short-term assistance. Significant predictors were identified in all three explored domains: structural shelter characteristics (sponsor, interpreter needed); clinical characteristics (access to health providers, clinic on site, staff had no days off); population characteristics (census, compromised mental health alone, or in combination with chronic conditions and diseases with epidemic potential). Shelters sponsored by faith-based organizations were less likely to be in risk of rapid resource depletion. Shelters with large census demonstrated association with

    Sleep disturbance, a correlate of which is daytime napping, has been hypothesised to be associated with risk of breast and other cancers. We estimated relative risks (RR) of breast and other invasive cancers by the reported frequency of daytime napping in a large prospective cohort of middle-aged women in the UK. During an average of 7.4 years of follow-up, 20 058 breast cancers and 31 856 other cancers were diagnosed. Over the first 4 years of follow-up, daytime napping (sometimes/usually vs rarely/never) was associated with slightly increased risks of breast cancer (RR=1.10, 95% CI 1.06-1.15) and of other cancers (RR=1.12, 1.08-1.15), but the RRs decreased significantly with increasing follow-up time (P=0.001 and P=0.01, respectively, for trend). Four or more years after baseline, there was no elevated risk of breast cancer (RR=1.00, 0.96-1.05), and only marginally greater risk of other cancers (RR=1.04, 1.01-1.07). The effect of pre-clinical disease is a likely explanation for the short-term increased risk of breast and other cancers associated with daytime napping. © 2012 Cancer Research UK

    Controlled clinical trials have demonstrated the efficacy and safety of adalimumab in patients with moderate-to-severe Crohn's disease (CD), but there is, however, only limited long-term experience with adalimumab in daily practice. To assess the long-term effectiveness and safety of adalimumab in a multicenter cohort of practice-based patients with moderate-to-severe CD. We retrospectively reviewed the charts of CD patients who received adalimumab over a 3-year period. Disease severity was scored using the Harvey-Bradshaw index (HBI). Remission was defined as an HBI of 3 points at evaluation compared to the baseline. Univariate logistic regression analysis was used to identify the predictive variables associated with response. The charts of 55 patients were reviewed; remission and response rates observed at weeks 4-6 were 52.7 and 83.6%, respectively. Remission was maintained at weeks 12, 24 and 52 in 89.6, 72.4 and 44.7% of patients, respectively. Remission and response rates were not influenced by smoking status, disease location or duration, the first month total dose, or previous infliximab therapy. The remission rate at weeks 4-6 was significantly higher in patients intolerant of infliximab as compared to those who lost response to this drug. Adalimumab was well tolerated overall. Adalimumab can be considered a suitable option in patients with moderate-to-severe CD, demonstrating sustained long-term effectiveness. Copyright (c) 2010 S. Karger AG, Basel.

    2010-01-01

    Full Text Available Non-communicable diseases (NCDs represent among the most common and debilitating conditions seen in primary care. Patients’ care will often involves multiple providers and follow-up requires persistence by patients and clinicians alike, therefore ideal outcomes are often difficult to achieve. The need for better disease management policies and practice is growing. This is due to the changing demographic profile of the population, the increasing cost of managing people in acute care hospitals and the availability of new technologies and services. All these changes enable a different care paradigm which is more cost effective and provides people with chronic conditions an improved quality of life. Management of the NCDs therefore offers an excellent opportunity to practice chronic disease management - a systems approach designed to ensure excellent care. The NCD team has developed a comprehensive approach to chronic disease care. We would like to describe the NCD Program in Ampangan Health Clinic which represents many typical government health clinics in Malaysia and the processes by which it was developed. Included are specific examples of the tools and how they can be used by individual clinicians incaring for patients. The integration of Chronic Disease Management Services into health care systems is the direction being undertaken to tackle the burden of chronic disease. Disease management supports the shift in healthcare from an emphasis on managing the acute episode to managing the entire disease course, highlighting both prevention and maintenance of wellbeing for patients with chronic diseases. Disease management promotes better integration and coordination of care across all aspects of the health sector.

    Full Text Available BACKGROUND: Primary refractory disease is a main challenge in the management of non-Hodgkin's Lymphoma (NHL. This survey was performed to define the rate of refractory disease to first-line therapy in B and T-cell NHL subtypes and the long-term survival of primary refractory compared to primary responsive patients. METHODS: Medical records were reviewed of 3,106 patients who had undergone primary treatment for NHL between 1982 and 2012, at the Hematology Centers of Torino and Bergamo, Italy. Primary treatment included CHOP or CHOP-like regimens (63.2%, intensive therapy with autograft (16.9%, or other therapies (19.9%. Among B-cell NHL, 1,356 (47.8% received first-line chemotherapy with rituximab. Refractory disease was defined as stable/progressive disease, or transient response with disease progression within six months. RESULTS: Overall, 690 (22.2% patients showed primary refractory disease, with a higher incidence amongst T-cell compared to B-cell NHL (41.9% vs. 20.5%, respectively, p<0.001. Several other clinico-pathological factors at presentation were variably associated with refractory disease, including histological aggressive disease, unfavorable clinical presentation, Bone Marrow involvement, low lymphocyte/monocyte ration and male gender. Amongst B-cell NHL, the addition of rituximab was associated with a marked reduction of refractory disease (13.6% vs. 26.7% for non-supplemented chemotherapy, p<0.001. Overall, primary responsive patients had a median survival of 19.8 years, compared to 1.3 yr. for refractory patients. A prolonged survival was consistently observed in all primary responsive patients regardless of the histology. The long life expectancy of primary responsive patients was documented in both series managed before and after 2.000. Response to first line therapy resulted by far the most predictive factor for long-term outcome (HR for primary refractory disease: 16.52, p<0.001. CONCLUSION: Chemosensitivity to primary

    Full Text Available The drugs we use to treat any condition – from an innocuous cough to a lifethreatening cancer – are the outcome of painstaking human clinical trials. These trials are the only way to credibly determine the safety and efficacy of drugs. In recent years there has been a clear shift in clinical trial sites from core developed countries like USA, European countries to developing countries like India, China, South American countries. This shift is related to challenges and opportunities like costs of trials, recruitment issues, and regulatory challenges in developed vs. developing countries. Developing countries and developed countries have their unique disease burden patterns based on various parameters like but not limited to age, health care facilities, health insurance, sanitary conditions, environmental issues, education, nutrition and GDP. Previous studies have reported that many of the important global diseases are not much explored in clinical trials and many published clinical trials have very less international health relevance. This study was aimed at finding the correlation between disease burdens, number of clinical trials done and trial success rates. We compared 2005-2010 Global Burden of Disease data for Germany, India and number of clinical trials from clinicaltrials.gov database done in the same period. Our findings indicated that there was a good correlation between the disease burden and clinical trials for Germany in 2005 and 2010. For India in 2005 there was a moderate positive correlation, 2010 data showed the improvement in India in terms of match between disease burden and clinical Trials. But careful observation of the data shows still a need for more trials on Communicable, maternal, neonatal and nutritional disorders.

    The severity of clinical activity of Crohn's disease is high during the first year after diagnosis and decreases thereafter. Approximately 50% of patients require steroids and immunosuppressants and 75% need surgery during their lifetime. The clinical course of patients with Crohn's disease first diagnosed at surgery has never been investigated. To assess the clinical course of Crohn's disease first diagnosed at surgery for acute abdomen and to evaluate the need for medical and surgical treatment in this subset of patients. Hospital clinical records of 490 consecutive Crohn's disease patients were reviewed. Patients were classified according to the Vienna criteria. Sex, extraintestinal manifestations, family history of inflammatory bowel diseases, appendectomy, smoking habit and medical/surgical treatments performed during the follow-up period were assessed. Kaplan-Meier survival method and Cox proportional hazards regression model. Of the 490 Crohn's disease patients, 115 had diagnosis of Crohn's disease at surgery for acute abdomen (Group A) and 375 by conventional clinical, radiological, endoscopic and histologic criteria (Group B). Patients in Group A showed a low risk of further surgery (Log Rank test pacute abdomen showed a low risk for reintervention and less use of steroids and immunosuppressants during follow-up than those not operated upon at diagnosis. Early surgery may represent a valid approach in the initial management of patients with Crohn's disease, at least in the subset of patients with ileal and complicated disease.

    Warren M Rozen

    Full Text Available INTRODUCTION: While Dupuytren's disease can cause disabling contractures requiring open surgery, a less-invasive option using Clostridium Histolyticum collagenase (CHC via percutaneous injection was recently reported. A recent prospective, randomized trial demonstrated few complications during 90 days follow-up, however did not assess any longer term follow-up for these patients. Long-term outcomes in this setting have not been adequately reported, and the current manuscript aims to identify late complications from the clinical use of percutaneous CHC. METHODS: The current manuscript reports an extended 12-month follow-up for a cohort of twelve of patients enrolled in the original prospective, randomized trial, treated at a single institution. An analysis of complications requiring surgical intervention was undertaken. RESULTS: Two of twelve patients reported debilitating pain and triggering requiring surgical intervention. Extensive deep-tissue scarring and adhesions were identified, providing the first visual and qualitative analysis of the pathologic effects of CHC. CONCLUSION: Late complications from CHC use can and have occurred, outside the follow-up period of the initial phase III trials. Longer term follow-up of such patients is thus essential, and further investigation and characterization of the late effects of CHC use is warranted.

    Full Text Available Cardiac diseases in canines are an extensively studied phenomenon all over the world but meagre information has been reported in India. Certain problems, including historical, physical, and laboratory abnormalities, are associated with cardiovascular or pulmonary disease. In India however, the recognition of canine cardiac diseases has been delayed, and ignored on account of lack of awareness and knowledge by the owner and inadequate diagnostic facility to a field veterinarian. Considering the above facts, the present study was undertaken in Gujarat to survey the prevalence of common cardiac diseases in hospital population of dogs along with the clinical symptoms which often goes undetected due to lack of proper diagnostic techniques to be implied and the most forms of heart disease may be present for many years before any evidence of failure develops. In the present study most of the clinical cases of cardiac diseases were presented with a history of nocturnal coughing (seven cases; 2.55%, exercise intolerance (five cases; 1.82%, partial or complete anorexia (five cases; 1.82%, swelling in abdominal area (four cases; 1.45%, dullness and depression (two cases; 0.72%, cachexia and hepatojugular pulsation (one case each; 0.36% each at times.

    Preclinical and post-mortem studies suggest that Alzheimer disease (AD) causes cerebrovascular dysfunction, and therefore may enhance susceptibility to cerebrovascular disease (CVD). The objective of this study was to investigate this association in a memory clinic population. The AD biomarkers CSF amyloid β42, amyloid β40 and APOE-ε4 status have all been linked to increased CVD risk in AD, and therefore the first aim of this study was to analyze the association between these biomarkers and CVD. In 92 memory clinic patients the cross-sectional association between AD biomarkersand the severity of CVD was investigated with linear regression analysis. Additionally, we studied whether AD biomarkers modified the relation between vascular risk factors and CVD. CVD was assessed on MRI through a visual rating scale.Analyses were adjusted for age. The second aim of this study was to investigate the association between clinical AD and CVD, where 'clinical AD' was defined as follows: impairment in episodic memory, hippocampal atrophy and an aberrant concentration of cerebrospinal fluid (CSF) biomarkers. 47 of the 92 patients had AD. No association between CSF amyloid β42, amyloid β40 or APOE-ε4 status and CVD severity was found, nor did these AD biomarkers modify the relation between vascular risk factors and CVD. Clinical AD was not associated with CVD severity (p=0.83). Patients with more vascular risk factors had more CVD, but this relationship was not convincingly modified by AD (p=0.06). In this memory clinic population, CVD in patients with AD was related to vascular risk factors and age, comparable to patients without AD. Therefore, in our study, the preclinical and post-mortem evidence that AD would predispose to CVD could not be translated clinically. Further work, including replication of this work in a different and larger sample, is warranted.

    Full Text Available Periodontal disease has very complex and multi factor etiology. Plaque bacteria is the main cause of periodontal disease and another risk factor that also plays a role is a smoking habit. Cigarette product such as nicotine can influence the development of periodontal disease that can directly and systemically damage the function of PMN cell. The research was conducted by taking a clinical examination on the smoking influence that covers the number of cigarettes and the period of smoking, and kind of cigarette to the worse of periodontal disease, and by measuring the epithelial attachment loss and the bleeding index. The research was conducted to 152 male aged 20-45 years old, comprised 80 smokers and 72 nonsmokers at the Clinic of Faculty of Dentistry Universitas Indonesia, Jakarta. The result of the research showed that smoking gave influence on the worse of the periodontal disease. There was a profound relationship between the smoking period and the number of cigarettes consumed everyday indicated by the epithelial attachment loss. Smoking did not enhance gingival bleeding. The relationship between kinds of cigarette and the gingival bleeding score and the epithelial attachment loss did not show a significant bleeding.

    Purpose of review In this article, we review sarcopenia in chronic kidney disease (CKD). We aim to present how definitions of sarcopenia from the general population may pertain to those with CKD, its assessment by clinicians and emerging therapies for sarcopenia in CKD. For this review, we limit our description and recommendations to patients with CKD who are not on dialysis. Recent findings Poorer parameters of lean mass, strength and physical function are associated with worsening patient-centered outcomes such as limiting mobility, falls and mortality in CKD; however, the magnitude of these associations are different in those with and without CKD. Sarcopenia in CKD is a balance between skeletal muscle regeneration and catabolism, which are both altered in the uremic environment. Multiple pathways are involved in these derangements, which are briefly reviewed. Differences between commonly used terms cachexia, frailty, protein-energy wasting, dynapenia and sarcopenia are described. Therapeutic options in predialysis CKD are not well studied; therefore, we review exercise options and emerging pharmacological therapies. Summary Sarcopenia, now with its own International Classification of Diseases, 10th Revision (ICD-10) code, is of importance clinically and should be accounted for in research studies in patients with CKD. Multiple therapies for sarcopenia are in development and will hopefully be available for our patients in the future. PMID:28198733

    Full Text Available With the demographic shift of the global population towards longer life expectancy, the number of people living with Alzheimer’s disease (AD has rapidly expanded and is projected to triple by the year 2050. Current treatments provide symptomatic relief but do not affect the underlying pathology of the disease. Therapies that prevent or slow the progression of the disease are urgently needed to avoid this growing public health emergency. Insights gained from decades of research have begun to unlock the pathophysiology of this complex disease and have provided targets for disease modifying therapies. In the last decade, few therapeutic agents designed to modify the underlying disease process have progressed to clinical trials and none have been brought to market. With the focus on disease modification, biomarkers promise to play an increasingly important role in clinical trials. Six biomarkers have now been included in diagnostic criteria for AD and are regularly incorporated into clinical trials. Three biomarkers are neuroimaging measures—hippocampal atrophy measured by magnetic resonance imaging (MRI, amyloid uptake as measured by Pittsburg compound B positron emission tomography (PiB PET, and decreased fluorodeoxyglucose (18F uptake as measured by positron emission tomography (FDG PET—and three are sampled from fluid sources—cerebrospinal fluid (CSF levels

  16. The antiplatelet effects of nitrates: is it of clinical significance in patients with cardiovascular disease?

    2010-01-01

    Organic nitrates have been used for over a century in cardiovascular therapy and are still widely used in the treatment of acute coronary syndromes, chronic angina pectoris, and congestive heart failure. Nitrates, together with sodium nitroprusside, generally referred to as nitrovasodilators, exert their biologic effects via the release of nitric oxide. They are also known as nitric oxide donors. The mechanism of action of these drugs is traditionally believed to lie in their arterial vasodilation and venodilation effects, resulting in an improvement of coronary artery blood supply and/or reduction of cardiac workload in the treatment of coronary artery disease and congestive heart failure. Recently it has been recognized that these drugs also have intrinsic antiplatelet and antithrombotic effects, demonstrated both in vitro and in vivo, which would add further rationale for the use of these drugs in atherothrombotic diseases. Research has shown that nitrovasodilators can nonselectively inhibit platelet aggregation induced by multiple stimuli. However, clinical trials have yielded conflicting results regarding clinical outcome, especially with long-term nitrate use. The potentially beneficial effects of nitrates could be negated by the development of tolerance and the generation of deleterious oxidative stress causing endothelial dysfunction during continuous nitrate administration. Much progress has been made in the development of new nitric oxide donors devoid of oxidant-generating properties. Novel combination therapies with nitrovasodilators plus antioxidants or agents with antioxidant properties have shown promise in reducing or reversing tolerance, potentiating antiplatelet effects, and improving clinical outcome. It is expected that clinical introduction of novel nitrovasodilator regimens will provide a new approach to the prevention and treatment of atherothrombotic diseases. Large-scale clinical trials will ultimately provide the evidence-based answers.

    With widespread adoption of transcatheter aortic valve replacement, there has been a change in the approach to management of valvular heart disease. New interest has taken hold in transcatheter therapies for valvular heart disease, as well as research into pathophysiology and progression of disease. Additionally, several key trials have further refined our understanding of surgical management of valvular heart disease. This review will elucidate recent clinical trial data leading to changes in practice. There have been several landmark trials expanding the indications for transcatheter aortic valve replacement. Additionally, although still early, trials are beginning to demonstrate the feasibility and safety of transcatheter mitral valves. Options for transcatheter management of right-sided valvular disease continue to evolve, and these are areas of active investigation. The emergence of novel therapies for valvular heart disease has expanded the management options available, allowing physicians to better individualize treatment of patients with valvular heart disease. This review will focus on the recent (within 2 years) trials in this field of interest.

    Full Text Available Immunoglobulin G4-related disease(IgG4-related diseasehas received lots of attention in medical community as a recently recognized fibro-inflammatory condition. It is characterized by infiltration of IgG4-immunopositive plasmacytes and concentration of elevated serum IgG4. IgG4-related disease shows organ enlargement or nodular/hyperplastic lesions in various organs including the pancreas, hepatobiliary tract and orbit, which is called IgG4-related orbital disease. The diagnostic criteria for IgG4-related disease and IgG4-related orbital disease has recently been established, which is based on clinical, imaging and histopathologic features of the orbital lesions. Besides, attention should be drawn to the differentiation from other diseases. The treatment is empirical including corticosteroids, immunosuppressive drugs, radiotherapy, and rituximab. This article reviews clinical progression of IgG4-related orbital disease.

    Norrie disease (ND) is an X-linked recessive disorder characterized by congenital blindness, progressive sensorineural hearing loss and cognitive impairment. The ocular phenotype has been well described, while the extraocular manifestations of the disorder are not well understood. We present the data from the Norrie Disease Registry, which consists of 56 patients with detailed clinical histories and genotype data. This study represents the largest, detailed investigation into the phenotypic spectrum of ND to date and more importantly expands knowledge of the extraocular clinical manifestations. We identify several novel aspects of the syndrome that will improve the management of these patients. In particular, we expand our understanding of the neurologic manifestations in ND and identify a chronic seizure disorder in approximately 10% of all patients. In addition, details of the hearing phenotype are described including the median age of onset (12 years of age) and how genotype affects onset. Moreover, we find vascular disease to be a significant component of ND; and vascular health should be, in the future, a component of patient clinical care. In summary, the results expand our understanding of the phenotypic variability and genotypic heterogeneity in ND patients. Copyright © 2012 Wiley Periodicals, Inc.

    Noise and artifacts are inherent contaminating components and are particularly present in Holter electrocardiogram (ECG) monitoring. The presence of noise is even more significant in long-term monitoring (LTM) recordings, as these are collected for several days in patients following their daily activities; hence, strong artifact components can temporarily impair the clinical measurements from the LTM recordings. Traditionally, the noise presence has been dealt with as a problem of non-desirable component removal by means of several quantitative signal metrics such as the signal-to-noise ratio (SNR), but current systems do not provide any information about the true impact of noise on the ECG clinical evaluation. As a first step towards an alternative to classical approaches, this work assesses the ECG quality under the assumption that an ECG has good quality when it is clinically interpretable. Therefore, our hypotheses are that it is possible (a) to create a clinical severity score for the effect of the noise on the ECG, (b) to characterize its consistency in terms of its temporal and statistical distribution, and (c) to use it for signal quality evaluation in LTM scenarios. For this purpose, a database of external event recorder (EER) signals is assembled and labeled from a clinical point of view for its use as the gold standard of noise severity categorization. These devices are assumed to capture those signal segments more prone to be corrupted with noise during long-term periods. Then, the ECG noise is characterized through the comparison of these clinical severity criteria with conventional quantitative metrics taken from traditional noise-removal approaches, and noise maps are proposed as a novel representation tool to achieve this comparison. Our results showed that neither of the benchmarked quantitative noise measurement criteria represent an accurate enough estimation of the clinical severity of the noise. A case study of long-term ECG is reported

    Autoinflammatory diseases are clinical conditions with inflammatory manifestations that present in a periodic or persistent manner and are caused by acquired or hereditary disorders of the innate immune response. In general, these diseases are more common in childhood, but cases have been reported in adults and are therefore important for all specialists. There are few references on these diseases in adults due to their low prevalence and underdiagnosis. The aim of this study is to review the scientific literature on these disorders to systematise their clinical, prognostic and treatment response characteristics in adults.

    Full Text Available Abstract Background Chronic kidney disease (CKD and end-stage renal disease (ESRD represent worldwide health problems with an epidemic extent. Therefore, attention must be given to the optimisation of patient care, as gaps in the care of CKD and ESRD patients are well documented. As part of a multidisciplinary patient care strategy, clinical pharmacy services have led to improvements in patient care. The purpose of this study was to summarise the available evidence regarding the role and impact of clinical pharmacy services for these patient populations. Methods A literature search was conducted using the Medline, Embase and International Pharmaceutical Abstracts databases to identify relevant studies on the impact of clinical pharmacists on CKD and ESRD patients, regarding disease-oriented and patient-oriented outcomes, and clinical pharmacist interventions on drug-related problems. Results Among a total of 21 studies, only four (19% were controlled trials. The majority of studies were descriptive (67% and before-after studies (14%. Interventions comprised general clinical pharmacy services with a focus on detecting, resolving and preventing drug-related problems, clinical pharmacy services with a focus on disease management, or clinical pharmacy services with a focus on patient education in order to increase medication knowledge. Anaemia was the most common comorbidity managed by clinical pharmacists, and their involvement led to significant improvement in investigated disease-oriented outcomes, for example, haemoglobin levels. Only four of the studies (including three controlled trials presented data on patient-oriented outcomes, for example, quality of life and length of hospitalisation. Studies investigating the number and type of clinical pharmacist interventions and physician acceptance rates reported a mean acceptance rate of 79%. The most common reported drug-related problems were incorrect dosing, the need for additional

    This paper discusses the authors' experience with hip resurfacing arthroplasty. Although introduced many years ago, the method did not gain wide popularity because of poor long-term outcomes. At present, owing to the introduction of metal-on-metal bearings and hybrid fixation techniques, short- and mid-term results are very good and encourage wider use of this technique, especially in the younger and more active patients whose results with standard total hip replacements would be unsatisfactory. We performed 13 hip resurfacing arthroplasties at our institution between August 1, 2005, and May 1, 2006. Twelve patients reported for the scheduled follow-up and were included in the study. Treatment outcomes were assessed according to the Harris Hip Score. The short-term outcomes of hip resurfacing arthroplasties are encouraging. In the study group there were no intraoperative complications, infections, peripheral nerve palsy, hip dislocations or clinically overt vein thrombosis. All of the patients reported complete or major pain relief. Clinical assessment according to the Harris Hip Score revealed improvement from an average of 57.7 (20.1) points preoperatively to an average of 87.7 (12) points after the surgery. Crutches were used for a maximum of 6 weeks postoperatively. All of the patients are currently able to walk without crutches with full weight-bearing. 1) Hip resurfacing arthroplasty seems to be an advisable method of operative management of younger, active patients, in whom standard THR would be associated with a high risk of failure; it allows THR to be postponed and carried out as a revision surgery with the acetabular component already in place. 2) Despite the good short- and mid-term results, the utility of this method should be evaluated with caution due to the lack of adequate long-term follow-up data.

    The Movement Disorder Society Clinical Diagnostic Criteria for Parkinson's disease (MDS-PD Criteria) was introduced by the Movement Disorder Society in 2015 for research purposes. However, its use for clinical diagnosis of Parkinson disease still needs further revision. This study compares the UK-Criteria versus MDS-PD Criteria in the clinical diagnosis of Parkinson disease referred to the China-Japan Friendship Hospital of Beijing, China. To compare the MDS-PD Criteria with the UK-Criteria and discuss the feasibility of the clinical application of MDS-PD Criteria as a general guide to clinical diagnosis of PD in Chinese PD patients. 150 patients of neurology clinic of China-Japan Friendship Hospital of Beijing were recruited in our research. They were divided into three groups: UK-Criteria group, MDS-PD Criteria group and a combined group of UK and MDS-PD Criteria. Clinical history was collected while physical and auxiliary examinations were done by a trained neurologist according to the corresponding criteria. An interrater reliability analysis using the Kappa statistic claimed substantial agreement (κ = 0.626) between the MDS-PD Criteria and the UK-Criteria. The differences between the diagnostic results of these two criteria were statistically significant by paired Chi-square test (p = 0.000). It was found that levodopa-induced dyskinesia had a good positive predictive value, while early bulbar impairment and inspiratory dysfunction presented a negative predictive value. The MDS-PD Criteria emphasize the importance of non-motor symptoms, keeping the motor symptoms as the core for the clinical diagnosis of PD, and establish categories of diagnosis features and levels of certainty which are more complete and organized to be used and replicated by non specialized physicians to evaluated patients with Parkinsonism. The higher sensitivity of MDS-PD Criteria compared with UK-Criteria is worth being widely used in clinical work.

    The purpose of this paper is to review information regarding the current guidelines for the clinical laboratory diagnosis of Lyme disease as set forth by the Centers for Disease Control and Prevention (CDC) to chiropractic physicians and to discuss the clinical utility of this testing. The CDC's website was reviewed to determine what their current recommendations are for the clinical laboratory testing of Lyme disease. The CDC's established guidelines recommend the use of a 2-tiered serologic testing algorithm for the evaluation of patients with suspected Lyme disease. This review provides doctors of chiropractic with information to remain current with the CDC's recommended guidelines for Lyme disease testing because patients may present to their office with the associated signs and symptoms of Lyme disease.

    Full Text Available Clinical treatment trials are increasingly being designed in primary mitochondrial disease (PMD, a phenotypically and genetically heterogeneous collection of inherited multi- system energy deficiency disorders that lack effective therapy. We sought to identify motivating factors and barriers to clinical trial participation in PMD.A survey study was conducted in two independent mitochondrial disease subject cohorts. A discovery cohort invited subjects with well-defined biochemical or molecularly- confirmed PMD followed at a single medical center (CHOP, n = 30/67 (45% respondents. A replication cohort included self-identified PMD subjects in the Rare Disease Clinical Research Network (RDCRN national contact registry (n = 290/1119 (26% respondents. Five-point Likert scale responses were analyzed using descriptive and quantitative statistics. Experienced and prioritized symptoms for trial participation, and patient attitudes toward detailed aspects of clinical trial drug features and study design.PMD subjects experienced an average of 16 symptoms. Muscle weakness, chronic fatigue, and exercise intolerance were the lead symptoms encouraging trial participation. Motivating trial design factors included a self-administered study drug; vitamin, antioxidant, natural or plant-derivative; pills; daily treatment; guaranteed treatment access during and after study; short travel distances; and late-stage (phase 3 participation. Relative trial participation barriers included a new study drug; discontinuation of current medications; disease progression; daily phlebotomy; and requiring participant payment. Treatment trial type or design preferences were not influenced by population age (pediatric versus adult, prior research trial experience, or disease severity.These data are the first to convey clear PMD subject preferences and priorities to enable improved clinical treatment trial design that cuts across the complex diversity of disease.

    Periodontal disease is one of the most frequent diseases affecting people all over the world. The relation between periodontal disease and diabetes mellitus raised the interest both of dentists and doctors treating metabolic diseases, as the two conditions influence one another. In our study, we analyzed a number of 75 patients with diabetes mellitus and periodontal disease that presented to the medical consultory for conditions of the dental maxillary system. The clinical study showed that periodontal disease and diabetes may affect young adults as well, still this pathological association more frequently appears after the age of 50. The disease was identified especially in the women living in urban area. The clinical examination of the dental maxillary system identified the presence of gingival ulcerations, dental calculus, gingival bleeding, radicular leftovers with anfractuous margins, fixed prostheses with an inappropriate cervical adjustment. Of the systemic diseases associated to periodontal disease and diabetes mellitus, there was observed that 66.66% of the patients also suffered from cardiovascular diseases (high blood pressure, ischemic cardiopathy, heart failure), and 37.33% suffered from obesity. The histopathological and immunohistochemical tests highlighted the presence of an inflammatory chronic, intense reaction, mainly formed of lymphocytes, plasmocytes, macrophages and granulocytes, heterogeneously disseminated and alteration of the structure of marginal and superficial periodontium. The inflammatory reaction in the patients with periodontal disease and diabetes was more intense than in the patients with periodontal disease without diabetes.

    The objective of this study is to describe rates of clinic attendance of youth with sickle cell disease prescribed hydroxyurea and examine potential demographic and medical factors related to consistent clinic attendance. Participants included 148 youth diagnosed with sickle cell disease and prescribed hydroxyurea during a single calendar year. Clinic attendance and potential demographic and medical factors related to attendance were extracted via systematic retrospective medical chart review. Youth attended 90.3% of scheduled appointments and 85.1% of youth attended at least 80% of scheduled clinic appointments during the study window. Adjusting for other factors, multivariate analysis revealed families with fewer children in the household, families with private insurance, youth experiencing fever, and youth not experiencing pain during the calendar year were more likely to consistently attend clinic visits. Adherence to clinic appointments is critical to optimizing health outcomes for youth with sickle cell disease and integral for adequate monitoring of youth prescribed hydroxyurea, in particular. Findings may aid providers in appropriately identifying possible barriers to clinic attendance to develop attendance promotion interventions.

    Intravenous cyclosporine therapy followed by oral cyclosporine therapy reduce the need for urgent surgery in steroid-refractory inflammatory bowel disease (IBD). Our objective is to report short- and long-term results of cyclosporine therapy in IBD patients. Thirteen patients with steroid-refractory IBD, seven patients with ulcerative colitis (UC), and six patients with Crohn's disease (CD) were treated with intravenous cyclosporine (4 mg/kg/day) for a mean period of 11.4+/-2.8 days (range, 4-15 days). Subsequently the patients were started on oral cyclosporine (8 mg/kg/day) and followed for a mean of 10.3+/-10 months (range, 1-30 months). Twelve patients responded to intravenous cyclosporine therapy. One patient with UC developed sepsis on the fourth day of intravenous cyclosporine therapy and needed urgent colectomy. Nine of 12 initial responders (6 patients with UC and 3 patients with CD) relapsed during follow-up despite oral cyclosporine and underwent elective surgery. One patient with CD relapsed 3 months after discontinuation of oral cyclosporine. Only two patients with CD are in long-term remission. There were no long-term side effects in any of the 13 treated patients. In conclusion, intravenous cyclosporine was effective in inducing remission or significant improvement in 12 of 13 patients with steroid-refractory IBD. However, with subsequent oral cyclosporine the remission could be maintained only for a short while. Each of the six patients with UC needed colectomy and three of the five patients with CD had intestinal resection within 12 months despite oral cyclosporine therapy.

    Study of MRI changes may be useful in diagnosis, prognosis and better understanding of the pathophysiology of Wilson's disease (WD). We aimed to describe and correlate the MRI abnormalities of the brain with clinical features in WD. MRI evaluation was carried out in 100 patients (57 males, 43 females; mean age 19.3±8.9 years) using standard protocols. All but 18 patients were on de-coppering agents. Their history, clinical manifestations and scores for severity of disease were noted. The mean duration of illness and treatment were 8.3±10.8 years and 7.5±7.1 years respectively. MRI of the brain was abnormal in all the 93 symptomatic patients. The most conspicuous observations were atrophy of the cerebrum (70%), brainstem (66%) and cerebellum (52%). Signal abnormalities were also noted: putamen (72%), caudate (61%), thalami (58%), midbrain (49%), pons (20%), cerebral white matter (25%), cortex (9%), medulla (12%) and cerebellum (10%). The characteristic T2-W globus pallidal hypointensity (34%), ''Face of giant panda'' sign (12%), T1-W striatal hyperintensity (6%), central pontine myelinosis (7%), and bright claustral sign (4%) were also detected. MRI changes correlated with disease severity scores (P<0.001) but did not correlate with the duration of illness. MRI changes were universal but diverse and involved almost all the structures of the brain in symptomatic patients. A fair correlation between MRI observations and various clinical features provides an explanation for the protean manifestations of the disease. (orig.)

    Our aim was to assess if term and preterm infants with volvulus showed different patterns with regard to pathogenesis, clinical presentation and outcome. We reviewed the medical records and imaging data of infants aged less than six months with volvulus treated in a single surgical referral centre from 2006-2013. Volvulus was diagnosed in 19 infants, with no anatomical anomaly in three of the 12 preterm infants and one of the seven term infants. Most cases (74%) presented during the first eight days of life. Later presentations occurred exclusively in preterm infants, with only one of the five having no anatomic anomalies. Bilious vomiting was the leading symptom in six of the seven term infants, while the symptoms in preterm infants were rather nonspecific. Intestinal necrosis, with the need for bowel resection, occurred in one term (14%) infant and nine (75%) preterm infants. The clinical presentation and outcome of volvulus differed between preterm and term infants, but the rate and distribution of underlying anomalies did not differ. Symptoms in preterm infants were often nonspecific and led to a delay in diagnosis. This might have contributed to the higher rate of intestinal necrosis in preterm infants. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    2012-01-01

    Over the past few decades, there has been an increase in the number of reports about newly recognized (atypical or unusual) manifestations of Graves' disease (GD), that are related to various body systems. One of these manifestations is sometimes the main presenting feature of GD. Some of the atypical manifestations are specifically related to GD, while others are also similarly seen in patients with other forms of hyperthyroidism. Lack of knowledge of the association between these findings and GD may lead to delay in diagnosis, misdiagnosis, or unnecessary investigations. The atypical clinical presentations of GD include anemia, vomiting, jaundice, and right heart failure. There is one type of anemia that is not explained by any of the known etiological factors and responds well to hyperthyroidism treatment. This type of anemia resembles anemia of chronic disease and may be termed GD anemia. Other forms of anemia that are associated with GD include pernicious anemia, iron deficiency anemia of celiac disease, and autoimmune hemolytic anemia. Vomiting has been reported as a presenting feature of Graves' disease. Some cases had the typical findings of hyperthyroidism initially masked, and the vomiting did not improve until hyperthyroidism has been detected and treated. Hyperthyroidism may present with jaundice, and on the other hand, deep jaundice may develop with the onset of overt hyperthyroidism in previously compensated chronic liver disease patients. Pulmonary hypertension is reported to be associated with GD and to respond to its treatment. GD-related pulmonary hypertension may be so severe to produce isolated right-sided heart failure that is occasionally found as the presenting manifestation of GD. PMID:22132347

    Sexually transmitted diseases continue to increase in the U.S. There is a growing need for financially viable models to ensure the longevity of safety-net sexually transmitted disease clinics, which provide testing and treatment to high-risk populations. This micro-costing analysis estimated the number of visits required to balance cost and revenue of a sexually transmitted disease clinic in a Medicaid expansion state. In 2017, actual and projected cost and revenues were estimated from the Rhode Island sexually transmitted disease clinic in 2015. Projected revenues for a hypothetical clinic offering a standard set of sexually transmitted disease services were based on Medicaid; private ("commercial") insurance; and institutional ("list price") reimbursement rates. The number of visits needed to cover clinic costs at each rate was assessed. Total operating cost for 2,153 clinic visits was estimated at $255,769, or $119 per visit. Laboratory testing and salaries each accounted for 44% of operating costs, medications for treatment 7%, supplies 5%, and 28% of visits used insurance. For a standard clinic offering a basic set of sexually transmitted disease services to break even, a projected 73% of visits need to be covered at the Medicaid rate, 38% at private rate, or 11% at institutional rate. Sexually transmitted disease clinics may be financially viable when a majority of visits are billed at a Medicaid rate; however, mixed private/public models may be needed if not all visits are billed. In this manner, sexually transmitted disease clinics can be solvent even if not all visits are billed to insurance, thus ensuring access to uninsured or underinsured patients.

    Potassium-competitive acid blocker (P-CAB) is a class of drug that competitively blocks the potassium-binding site of H+, K+-adenosine triphosphate (ATP)ase. Although the history of this class of drugs started over 30 years ago, clinical use of two P-CABs, revaprazan and vonoprazan, were only recently approved in Korea and Japan, respectively. Among them, vonoprazan has several advantages over conventional proton-pump inhibitors (PPIs), including rapid onset of action, long duration of acid suppression, fewer interindividual variations in terms of acid suppression, and minimum dietary influence on its action. These advantages of vonoprazan have been proved in clinical trials conducted for license approvals for several acid-related diseases. In this review article, current evidence of vonoprazan in the management of gastroesophageal reflux disease (GERD) will be summarized. Since the clinical trial data, as well as postmarketed clinical data, have consistently demonstrated superiority of vonoprazan over conventional PPIs in terms of achieving healing of mucosal breaks and maintaining the healing, it may provide an excellent, if not complete, option for fulfilling some of the unmet needs for current GERD therapy. The safety problem of vonoprazan is also discussed, as more pronounced hypergastrinemia inevitably ensues with its use. PMID:29383028

    Objective To compare the medium-term clinical and radiographic outcomes of Dynesys dynamic stabilization and posterior lumbar interbody fusion (PLIF) for treatment of multisegmental lumbar degenerative disease. Methods Fifty-seven patients with multisegmental lumbar degenerative disease underwent Dynesys stabilization (n = 26) or PLIF (n = 31) from December 2008 to February 2010. The mean follow-up period was 50.3 (range, 46-65) months. Clinical outcomes were evaluated using a visual analogue scale (VAS) and the Oswestry disability index (ODI). Radiographic evaluations included disc height and range of motion (ROM) of the operative segments and proximal adjacent segment on lumbar flexion-extension X-rays. The intervertebral disc signal change was defined by magnetic resonance imaging, and disc degeneration was classified by the Pfirrmann grade. Results The clinical outcomes including the VAS score and ODI were significantly improved in both groups at 3 months and the final follow-up, but the difference between the two was not significant. At the final follow-up, the disc height of stabilized segments in both groups was significantly increased; the increase was more notable in the Dynesys than PLIF group. The ROM of stabilized segments at the final follow-up decreased from 6.20° to 2.76° and 6.56° to 0.00° in the Dynesys and PLIF groups, respectively. There was no distinct change in the height of the proximal adjacent segment in the two groups. The ROM of the proximal adjacent segment in both groups increased significantly at the final follow-up; the change was significantly greater in the PLIF than Dynesys group. Only one case of adjacent segment degeneration occurred in the PLIF group, and this patient underwent a second operation. Conclusions Both Dynesys stabilization and PLIF can improve the clinical and radiographic outcomes of multisegmental lumbar degenerative disease. Compared with PLIF, Dynesys stabilization can maintain the mobility of the

    Full Text Available Abstract Background Coats' disease is a non-hereditary ocular disease, with no systemic manifestation, first described by Coats in 1908. It occurs more commonly in children and has a clear male predominance. Most patients present clinically with unilateral decreased vision, strabismus or leukocoria. The most important differential diagnosis is unilateral retinoblastoma, which occurs in the same age group and has some overlapping clinical manifestations. Case presentation A 4 year-old girl presented with a blind and painful right eye. Ocular examination revealed neovascular glaucoma, cataract and posterior synechiae. Although viewing of the fundus was impossible, computed tomography disclosed total exsudative retinal detachment in the affected eye. The eye was enucleated and subsequent histopathological evaluation confirmed the diagnosis of Coats' disease. Conclusion General pathologists usually do not have the opportunity to receive and study specimens from patients with Coats' disease. Coats' disease is one of the most important differential diagnoses of retinoblastoma. Therefore, It is crucial for the pathologist to be familiar with the histopathological features of the former, and distinguish it from the latter.

    Our own results of two-stage research are presented in the article. The first stage contains the retrospective analysis of 3682 X-ray examining of large bowel which were conducted in 2002-2004 to define the structure of colon disease and to determine gender differences. The second stage is prospective research which took place from 2003 to 2012 and 486 patients with diverticular disease were regularly observed. Following parameters were estimated: dynamics of complaints, life quality, clinical symptoms. Multiple X-ray and endoscopic examining were done with estimation of quantity and size of diverticula, changes of colon mucosa, comparison of X-ray and endoscopic methods in prognosis of complications. Two basic clinical morphological variants of diverticular disease (DD) of colon are made out as a result of our research. There are IBD-like and DD with ischemic component. The variants differ by pain characteristics, presence of accompanying diseases, life quality parameters and description of colon mucosa morphological research. We suppose that different ethiopathogenetic factors of development of both variants mentioned above influence the disease prognosis and selection of treatment.

    Paralleling the first 30 years of the Journal of Hepatology we have witnessed huge advances in our understanding of liver disease and physiology. Genetic advances have played no small part in that. Initial studies in the 1970s and 1980s identified the strong major histocompatibility complex associations in autoimmune liver diseases. During the 1990 s, developments in genomic technologies drove the identification of genes responsible for Mendelian liver diseases. Over the last decade, genome-wide association studies have allowed for the dissection of the genetic susceptibility to complex liver disorders, in which also environmental co-factors play important roles. Findings have allowed the identification and elaboration of pathophysiological processes, have indicated the need for reclassification of liver diseases and have already pointed to new disease treatments. In the immediate future genetics will allow further stratification of liver diseases and contribute to personalized medicine. Challenges exist with regard to clinical implementation of rapidly developing technologies and interpretation of the wealth of accumulating genetic data. The historical perspective of genetics in liver diseases illustrates the opportunities for future research and clinical care of our patients.

    Full Text Available We outline an automated computational and machine learning framework that predicts disease severity and stratifies patients. We apply our framework to available clinical data. Our algorithm automatically generates insights and predicts disease severity with minimal operator intervention. The computational framework presented here can be used to stratify patients, predict disease severity and propose novel biomarkers for disease. Insights from machine learning algorithms coupled with clinical data may help guide therapy, personalize treatment and help clinicians understand the change in disease over time. Computational techniques like these can be used in translational medicine in close collaboration with clinicians and healthcare providers. Our models are also interpretable, allowing clinicians with minimal machine learning experience to engage in model building. This work is a step towards automated machine learning in the clinic.

    The objective of this perspective is to present a separate disease description of "idiopathic canalicular inflammatory disease" and outline the diagnostic criteria and early experiences with its investigations and management. Retrospective case series of 44 canaliculi of 22 eyes of 11 patients presenting at a tertiary care Dacryology service over a period of 2 years with typical clinical patterns of inflammatory canaliculitis and its outcomes were studied. All the patients underwent microbiological work-up with culture and sensitivity, dacryoendoscopy imaging, serial Fourier domain ocular coherence tomography, and collagen vascular profiles. Stages in the evolution of the disease were studied. All patients were treated initially with topical steroids followed by punctal dilatation and placement of mini-monoka stents. Five patients in addition had a small biopsy from the inflamed portion of the vertical canaliculus. Stents were extubated at 6 weeks. Forty-four canaliculi were diagnosed to have idiopathic canalicular inflammatory disease during the study period. There was a female preponderance (81.8%, 9/11) and the mean age at presentation was 57 years. All patients presented with unilateral epiphora without any discharge, pain, or swelling. Collagen vascular profiles and screening for autoimmune diseases were negative. Clinical picture ranged from stages 1 to 5, consisting of edema, progressive centripetal vascularization, pouting of vascularized mucosa, membrane formation, and progressive scarring. The presentation begins in 1 eye and usually involves the other eye at a mean of 6 months. Ocular coherence tomography and dacryoendoscopy were of adjunctive value in the diagnosis. Histopathological examination was suggestive of a chronic inflammation. All patients had relentless progression to end-stage disease, although delayed significantly by steroids and monoka intubation. Idiopathic canalicular inflammatory disease has a distinct and typical clinical behavior and

    Full Text Available Peter Hedera Department of Neurology, Vanderbilt University Medical Center, Nashville, TN, USA Abstract: Wilson’s disease (WD, albeit relatively rare, is an important genetic metabolic disease because of highly effective therapies that can be lifesaving. It is a great imitator and requires a high index of suspicion for correct and timely diagnosis. Neurologic, psychiatric and hepatologic problems in WD are very nonspecific, and we discuss the most common clinical phenotypes. The diagnosis remains laboratory based, and here we review the most important challenges and pitfalls in laboratory evaluation of WD, including the emerging role of genetic testing in WD diagnosis. WD is a monogenic disorder but has very high allelic heterogeneity with >500 disease-causing mutations identified, and new insights into phenotype–genotype correlations are also reviewed. The gold standard of therapy is chelation of excessive copper, but many unmet needs exist because of possible clinical deterioration in treated patients and potential adverse effects associated with currently available chelating medications. We also review the most promising novel therapeutic approaches, including chelators targeting specific cell types, cell transplantation and gene therapy.

    In 1995, the Centers for Disease Control and Prevention granted a Cooperative Agreement Program award to the Infectious Diseases Society of America to develop a provider-based emerging infections sentinel network, the Emerging Infections Network (EIN). Over the past 17 years, the EIN has evolved into a flexible, nationwide network with membership representing a broad cross-section of infectious disease physicians. The EIN has an active electronic mail conference (listserv) that facilitates communication among infectious disease providers and the public health community, and also sends members periodic queries (short surveys on infectious disease topics) that have addressed numerous topics relevant to both clinical infectious diseases and public health practice. The article reviews how the various functions of EIN contribute to clinical care and public health, identifies opportunities to further link clinical medicine and public health, and describes future directions for the EIN.

    With the development of long-term disease modifying trials, changes in ADAS-Cog at 18 months will rise certainly many questions. We decided to look in the Real.fr study at the links between changes in cognition, ADAS-Cog and function. A total of 346 Alzheimer's patients with ADAS-cog at entry and at 18 months. were eligible for this analysis. These patients were on average 77.44 years old and 254 (72.36%) were women. The great majority lived at home and about 93% were treated with a cholinesterase inhibitor at baseline. Thirty three patients (9%) had a gain of more than 2 points at the ADAS-cog at 18 months (Group I, improvement); 130 (38%) were considered as stable, the reference group (Group II ) characterized by a stability at the ADAS-cog: decline of 2 points to gain of 2 points, 112 subjects (32%) had a moderate decline between 2 and 7 at the ADAScog (Group III) and finally 71 subjects (21%) had a severe impairment more than seven points at the ADAS-cog. A loss of one Basic ADL is certainly highly relevant, and such a change was found at 18 months in more than half of the subjects, which is not surprising for a long-term evolution in mild to moderate AD. An impairment of more than 7 points at the ADAS-cog was found in 21% of the subjects at 18 months and was associated with loss.

    Echocardiographic screening is under consideration as a disease control strategy for rheumatic heart disease (RHD). However, clinical outcomes of young people with screening-detected RHD are unknown. We aimed to describe the outcomes for a cohort with screening-detected RHD, in comparison to patients with clinically-diagnosed RHD. A retrospective cohort study included all young people with screening-detected RHD in the Central Division of Fiji in the primary cohort. Screen-negative and clinically-diagnosed comparison groups were matched 1:1 to the primary cohort. Data were collected on mortality, clinical complications and healthcare utilisation from the electronic and paper health records and existing databases. Seventy participants were included in each group. Demographic characteristics of the groups were similar (median age 11years, 69% female, median follow-up 7years). There were nine (12.9%) RHD-related deaths in the clinically-diagnosed group and one (1.4%) in the screening-detected group (Incident Rate Ratio: 9.6, 95% CI 1.3-420.6). Complications of RHD were observed in 39 (55.7%) clinically-diagnosed cases, four (20%) screening-detected cases and one (1.4%) screen-negative case. There were significant differences in the cumulative complication curves of the groups (pFiji. The prognosis of clinically-diagnosed RHD remains poor, with very high mortality and complication rates. Further studies in other settings will inform RHD screening policy. Comprehensive control strategies are required for disease prevention. Copyright © 2017 Elsevier B.V. All rights reserved.

    Major depression and Alzheimer׳s disease (AD) are often observed in the elderly. The identification of specific markers for these diseases could improve their screening. The aim of this study was to investigate long-term odor recognition memory in depressed and AD patients, with a view to identifying olfactory markers of these diseases. We included 20 patients with unipolar major depressive episodes (MDE), 20 patients with mild to moderate AD and 24 healthy subjects. We investigated the cognitive profile and olfactory memory capacities (ability to recognize familiar and unfamiliar odors) of these subjects. Olfactory memory test results showed that AD and depressed patients were characterized by significantly less correct responses and more wrong responses than healthy controls. Detection index did not differ significantly between patients with major depression and those with AD when the results were analyzed for all odors. However, MDE patients displayed an impairment of olfactory memory for both familiar and unfamiliar odors, whereas AD subjects were impaired only in the recognition of unfamiliar odors, with respect to healthy subjects. If preservation of olfactory memory for familiar stimuli in patients with mild to moderate AD is confirmed, this test could be used in clinical practice as a complementary tool for diagnosis.

    A large percentage of patients with Parkinson's disease (PD) develop motor fluctuations, dyskinesias, and severe non-motor symptoms within 3 to 5 years of starting dopaminergic therapy, and these motor complications are refractory to treatment. Several authors refer to this stage of the disease as advanced Parkinson's disease. To define the clinical manifestations of advanced PD and the risk factors for reaching this stage of the disease. This consensus document has been prepared by using an exhaustive literature search and by discussion of the contents by an expert group on movement disorders of the Sociedad Española de Neurología (Spanish Neurology Society), coordinated by two of the authors (JK and MRL). Severe motor fluctuations and dyskinesias, axial motor symptoms resistant to levodopa, and cognitive decline are the main signs in the clinical phenotype of advanced PD.

    Publication of the DEWS report in 2007 established the state of the science of dry eye disease (DED). Since that time, new evidence suggests that a rethinking of traditional concepts of dry eye disease is in order. Specifically, new evidence on the epidemiology of the disease, as well as strategies for diagnosis, have changed the understanding of DED, which is a heterogeneous disease associated with considerable variability in presentation. These advances, along with implications for clinical care, are summarized herein. The most widely used signs of DED are poorly correlated with each other and with symptoms. While symptoms are thought to be characteristic of DED, recent studies have shown that less than 60% of subjects with other objective evidence of DED are symptomatic. Thus the use of symptoms alone in diagnosis will likely result in missing a significant percentage of DED patients, particularly with early/mild disease. This could have considerable impact in patients undergoing cataract or refractive surgery as patients with DED have less than optimal visual results. The most widely used objective signs for diagnosing DED all show greater variability between eyes and in the same eye over time compared with normal subjects. This variability is thought to be a manifestation of tear film instability which results in rapid breakup of the tearfilm between blinks and is an identifier of patients with DED. This feature emphasizes the bilateral nature of the disease in most subjects not suffering from unilateral lid or other unilateral destabilizing surface disorders. Instability of the composition of the tears also occurs in dry eye disease and shows the same variance between eyes. Finally, elevated tear osmolarity has been reported to be a global marker (present in both subtypes of the disease- aqueous-deficient dry eye and evaporative dry eye). Clinically, osmolarity has been shown to be the best single metric for diagnosis of DED and is directly related to

    In light of the excellent long-term survival of childhood cancer patients, it is imperative to screen for factors affecting health, function, and quality of life in long-term survivors. To comprehensively assess chemotherapy-induced peripheral neuropathy in childhood cancer survivors to define disease burden and functional effect and to inform screening recommendations. In this cross-sectional observational study, cancer survivors who were treated with chemotherapy for extracranial malignancy before age 17 years were recruited consecutively between April 2015 and December 2016 from a single tertiary hospital-based comprehensive cancer survivorship clinic and compared with healthy age-matched controls. Investigators were blinded to the type of chemotherapy. A total of 169 patients met inclusion criteria, of whom 48 (28.4%) were unable to be contacted or declined participation. Chemotherapy agents known to be toxic to peripheral nerves. The clinical peripheral neurological assessment using the Total Neuropathy Score was compared between recipients of different neurotoxic chemotherapy agents and control participants and was correlated with neurophysiological, functional, and patient-reported outcome measures. Of the 121 childhood cancer survivors included in this study, 65 (53.7%) were male, and the cohort underwent neurotoxicity assessments at a median (range) age of 16 (7-47) years, a median (range) 8.5 (1.5-29) years after treatment completion. Vinca alkaloids and platinum compounds were the main neurotoxic agents. Clinical abnormalities consistent with peripheral neuropathy were common, seen in 54 of 107 participants (50.5%) treated with neurotoxic chemotherapy (mean Total Neuropathy Score increase, 2.1; 95% CI, 1.4-2.9; P neuropathy (mean amplitude reduction, 5.8 μV; 95% CI, 2.8-8.8; P Neuropathy Score.

    Chronic obstructive pulmonary disease and congestive heart failure are two increasingly prevalent chronic diseases. Although care for these patients often is provided by different clinical teams, both disease conditions have much in common. In recent decades, more knowledge about the systemic impact of both diseases has become available, highlighting remarkable similarities in terms of prognostic factors and disease management. Rehabilitation programs deal with the systemic consequences of both diseases. Although clinical research also is conducted by various researchers investigating chronic obstructive pulmonary disease and chronic heart failure, it is worthwhile to compare the progress in relation to these two diseases over recent decades. Such comparison, the purpose of the current review, may help clinicians and scientists to learn about progress made in different, yet related, fields. The current review focuses on the similarities observed in the clinical impact of muscle weakness, the mechanisms of muscle dysfunction, the strategies to improve muscle function, and the effects of exercise training on chronic obstructive pulmonary disease and chronic heart failure.

    People are exposed to hundreds of substances daily, some of which may induce pulmonary injury. Occupational Lung Disease diagnosis requires 4 elements: Exposure to the harmful agent, adequate latency between exposure and beginning of the symptoms, syndrome with post-exposure abnormalities, and exclusion of other conditions which may otherwise explain signs and symptoms. Several occupational lung disease classifications based on structural or functional injury, type of agent, or both have been proposed. Generally, 5 groups are considered: Pneumoconiosis, hypersensitivity pneumonitis, toxic fumes exposure, asthma, and occupational lung infections. Conventional radiographs and in specific situations, CT, are crucial elements for the diagnosis of Occupational Lung Disease. In the patient with respiratory symptoms and altered imaging studies, the possibility of Occupational Lung Disease should be considered. Radiologist should be familiar the variety of substances that cause these entities and their radiological features. In this article Occupational Lung diseases are reviewed, including diagnostic criteria, classification, physiopathology, clinical and radiological manifestations as well as their corresponding histopathological features.

    In psychotic disorders, impairments in cognition have been associated with both clinical and functional outcome, while deficits in social cognition have been associated with functional outcome. As an extension to a recent report on neurocognition and short-term clinical outcome in first-episode psychosis (FEP), the current study explored whether social cognitive deficits could also identify poor short-term clinical outcome among FEP patients. We defined the social-cognition domain based on the scores from the Hinting Task and the Four Factor Tests of Social Intelligence. Data were collected in 45 FEP patients and 26 healthy controls. The patients were divided into good- and poor-outcome groups based on clinical data at six months following initiation of treatment. Social cognition was compared among 27 poor-outcome, 18 good-outcome, and 26 healthy-control participants. Outcome groups significantly differed in the social cognition domain (z-scores: poor outcome=-2.0 [SD=1.4]; good outcome=-1.0 [SD=1.0]; p=0.005), with both groups scoring significantly lower than the control group (psocial cognition appears to be compromised in all FEP patients compared to healthy controls. More interestingly, significant differences in social cognitive impairments exist between good and poor short-term clinical outcome groups, with the largest effect found in the Cartoon Predictions subtest.

    2011-05-01

    The two closely linked specialties of clinical microbiology and infectious diseases face important challenges. We report the consensus of clinical microbiologists and infectious disease physicians assembled by the European Society for Clinical Microbiology and Infectious Diseases. Both specialties have different training requirements in different European countries and are not universally recognised as professions. The specialties are rapidly evolving as they adapt to the changing demands within hospital practice, including the need to deal with emerging infections, rapidly increasing internationalisation, and immigration. Clinical microbiology needs to develop and master technological advances such as laboratory automation and an avalanche of new methods for rapid diagnostics. Simultaneously, the pressure for concentration, amalgamation, and out-sourcing of laboratory services is ever-increasing. Infectious disease physicians have to meet the professional challenge of subspecialisation and the continual need to find new niches for their skills. Despite these challenges, each of these specialties continues to thrive in Europe and will enjoy important opportunities over the next few years. The recently formed European Centre for Disease Prevention and Control in Stockholm, Sweden, will increase demands in areas of surveillance of infectious diseases and antimicrobial resistance on both specialties.

    2017-01-01

    Full Text Available Paget’s disease of bone (PDB is a chronic localized skeletal disease that belongs to a group of metabolic osteopathies and is characterized by impaired bone remodeling to form foci of increased bone resorption followed by replacement with an excessive amount of defective, less durable bone that is prone to deformities and pathologic fractures. The course of PDB shows three stages: rarefaction, compaction, and coarse-trabecular remodeling – each of which is characterized by certain clinical, biochemical, and radiological manifestations. The majority of the clinical manifestations of the disease are associated with skeletal injury. The disease is characterized by the appearance of bone and joint pain in case of secondary osteoarthritis, bone deformities, pathological fractures, hearing loss due to damage to the skull bones, etc. In many patients, the disease is asymptomatic and detected incidentally after finding a high serum alkaline phosphatase activity or during bone X-ray for any pathological processes, but it can be diagnosed fairly late in the development of complications, as shown in the clinical examples. A combination of clinical, biochemical, morphological data and radiological findings allows for a diagnosis. The use of bisphosphonates is the method of choice for the treatment of PDB.

    Metabonomics is a powerful and promising analytic tool that allows assessment of global low-molecular-weight metabolites in biological systems. It has a great potential for identifying useful biomarkers for early diagnosis, prognosis and assessment of therapeutic interventions in clinical practice. The aim of this review is to provide a brief summary of the recent advances in UPLC-based metabonomic approach for biomarker discovery in a variety of diseases, and to discuss their significance in clinical chemistry. All the available information on UPLC-based metabonomic applications for discovering biomarkers of diseases were collected via a library and electronic search (using Web of Science, Pubmed, ScienceDirect, Springer, Google Scholar, etc.). Metabonomics has been used in clinical chemistry to identify and evaluate potential biomarkers and therapeutic targets in various diseases affecting the liver (hepatocarcinoma and liver cirrhosis), lung (lung cancer and pneumonia), gastrointestinal tract (colorectal cancer) and urogenital tract (prostate cancer, ovarian cancer and chronic kidney disease), as well as metabolic diseases (diabetes) and neuropsychiatric disorders (Alzheimer's disease and schizophrenia), etc. The information provided highlights the potential value of determination of endogenous low-molecular-weight metabolites and the advantages and potential drawbacks of the application of UPLC-based metabonomics in clinical setting.

    Fatigue is a common symptom with numerous causes. Severe fatigue is thought to be an important manifestation of post-treatment Lyme disease syndrome. The frequency with which severe fatigue occurs as a long-term sequela in prospectively followed patients with Lyme disease is unknown. Patients with culture-confirmed Lyme disease who originally presented with erythema migrans have been evaluated annually in a prospective study to determine their long-term outcome. In 2011-2013, subjects were evaluated for fatigue using an 11-item Fatigue Severity Scale (FSS-11) that has been used in studies of post-treatment Lyme disease syndrome. An FSS-11 score of ≥4.0 is indicative of severe fatigue. A total of 100 subjects were assessed, 52% of whom were male; the mean age was 64.9 years (range, 42-86 years). The mean duration of follow-up was 15.4 years (range, 11-20 years). Nine subjects had severe fatigue but in none as a consequence of Lyme disease. Only 3 subjects were thought to possibly have persistent fatigue from Lyme disease. The FSS-11 value for these 3 individuals was less than 4, averaging 2.27, and none had functional impairment. Severe fatigue was found in 9 patients (9%) with culture-confirmed early Lyme disease at 11 to 20 years after presentation, but was due to causes other than Lyme disease. Fatigue of lesser severity was possibly due to Lyme disease, but was found in only 3% of 100 patients, and therefore is rarely a long-term complication of this infection.

    A clinical pharmacy service for managing the treatment of coronary artery disease in a health maintenance organization is described. Despite the proven benefits of aggressive risk factor modification for patients with coronary artery disease (CAD), there remains a treatment gap between consensus- and evidence-based recommendations and their application in patient care. In 1998, Kaiser Permanente of Colorado developed the Clinical Pharmacy Cardiac Risk Service (CPCRS) to focus on the long-term management of patients with CAD to improve clinical outcomes. The primary goals of the CPCRS are to increase the number of CAD patients on lipid-lowering therapy, manage medications shown to decrease the risk of future CAD-related events, assist in the monitoring and control of other diseases that increase cardiovascular risk, provide patient education and recommendations for nonpharmacologic therapy, and act as a CAD information resource for physicians and other health care providers. Using an electronic medical record and tracking database, the service works in close collaboration with primary care physicians, cardiologists, cardiac rehabilitation nurses, and other health care providers to reduce cardiac risk in the CAD population. Particular attention is given to dyslipidemia, blood pressure, diabetes mellitus, and tobacco cessation. Treatment with evidence-based regimens is initiated and adjusted as necessary. Over 11,000 patients are currently being followed by the CPCRS. A clinical pharmacy service in a large health maintenance organization provides cardiac risk reduction for patients with CAD and helps close treatment gaps that may exist for these patients.

    Advert health impacts associated with the PM2.5 exposure have been confirmed in mortality and cardiovascular diseases; however, findings of the influence of PM2.5 on respiratory diseases investigated among previous studies are still inconsistent. We investigated the short-term population-based associations between the respiratory clinic visits of children population and the PM2.5 exposure levels with considering both the spatiotemporal distributions of the ambient pollution and clinic visit data. We applied a spatiotemporal structured additive regression model to examine the concentration-response (C-R) association between daily children's respiratory clinic visits and PM2.5 concentrations. The analysis was performed separately on the four selected respiratory disease categories of the population-based dataset, obtained from Taiwan National Health Insurance database, covering the 41 districts in Taipei area during the period of 2005 to 2007. This study reveals a strong nonlinear C-R pattern that the PM2.5 increment can significantly affect respiratory health at PM2.5 concentration ≤ 18.17µg/m3 for both preschool children and schoolchildren. The elevated risks are especially present in the category of acute respiratory infections. PM2.5 increase is mostly non-significant to the more severe respiratory diseases, e.g., COPD and pneumonia, over the ranges of 8.85-92.45µg/m3. The significantly higher relative rate of respiratory clinic visit most likely concentrated at populated areas. We highlight the nonlinearity of the respiratory health impacts of PM2.5 on children's populations from the first study, to our knowledge, to investigate this population-based association. The strong nonlinearity can possibly cause the inconsistency of PM2.5 health impact assessments with linear assumptions.

    Clinical prediction models (CPMs) estimate the probability of clinical outcomes and hold the potential to improve decision making and individualize care. For patients with cardiovascular disease, there are numerous CPMs available although the extent of this literature is not well described. We conducted a systematic review for articles containing CPMs for cardiovascular disease published between January 1990 and May 2012. Cardiovascular disease includes coronary heart disease, heart failure, arrhythmias, stroke, venous thromboembolism, and peripheral vascular disease. We created a novel database and characterized CPMs based on the stage of development, population under study, performance, covariates, and predicted outcomes. There are 796 models included in this database. The number of CPMs published each year is increasing steadily over time. Seven hundred seventeen (90%) are de novo CPMs, 21 (3%) are CPM recalibrations, and 58 (7%) are CPM adaptations. This database contains CPMs for 31 index conditions, including 215 CPMs for patients with coronary artery disease, 168 CPMs for population samples, and 79 models for patients with heart failure. There are 77 distinct index/outcome pairings. Of the de novo models in this database, 450 (63%) report a c-statistic and 259 (36%) report some information on calibration. There is an abundance of CPMs available for a wide assortment of cardiovascular disease conditions, with substantial redundancy in the literature. The comparative performance of these models, the consistency of effects and risk estimates across models and the actual and potential clinical impact of this body of literature is poorly understood. © 2015 American Heart Association, Inc.

    Several molecular subtypes of sporadic Creutzfeldt–Jakob disease have been identified and electroencephalogram and cerebrospinal fluid biomarkers have been reported to support clinical diagnosis but with variable utility according to subtype. In recent years, a series of publications have demonstrated a potentially important role for magnetic resonance imaging in the pre-mortem diagnosis of sporadic Creutzfeldt–Jakob disease. Magnetic resonance imaging signal alterations correlate with distinct sporadic Creutzfeldt–Jakob disease molecular subtypes and thus might contribute to the earlier identification of the whole spectrum of sporadic Creutzfeldt–Jakob disease cases. This multi-centre international study aimed to provide a rationale for the amendment of the clinical diagnostic criteria for sporadic Creutzfeldt–Jakob disease. Patients with sporadic Creutzfeldt–Jakob disease and fluid attenuated inversion recovery or diffusion-weight imaging were recruited from 12 countries. Patients referred as ‘suspected sporadic Creutzfeldt–Jakob disease’ but with an alternative diagnosis after thorough follow up, were analysed as controls. All magnetic resonance imaging scans were assessed for signal changes according to a standard protocol encompassing seven cortical regions, basal ganglia, thalamus and cerebellum. Magnetic resonance imaging scans were evaluated in 436 sporadic Creutzfeldt–Jakob disease patients and 141 controls. The pattern of high signal intensity with the best sensitivity and specificity in the differential diagnosis of sporadic Creutzfeldt–Jakob disease was identified. The optimum diagnostic accuracy in the differential diagnosis of rapid progressive dementia was obtained when either at least two cortical regions (temporal, parietal or occipital) or both caudate nucleus and putamen displayed a high signal in fluid attenuated inversion recovery or diffusion-weight imaging magnetic resonance imaging. Based on our analyses, magnetic

    Heart failure with mid-range left ventricular ejection fraction (HFmrEF) is a poorly characterized population as it has been studied either in the context of HF with reduced (HFrEF) or preserved (HFpEF) left ventricular ejection fraction (LVEF) depending on applied LVEF cutoffs. We sought to investigate the clinical profile, in-hospital management, and short-term outcome of HFmrEF patients in comparison with those with HFrEF or HFpEF in a large acute HF cohort. The Acute Heart Failure Global Registry of Standard Treatment (ALARM-HF) included 4953 patients hospitalized for HF in nine countries in Europe, Latin America, and Australia. Baseline characteristics, clinical presentation, in-hospital therapies, and short-term mortality (all-cause in-hospital or 30-day mortality, whichever first) were compared among HFrEF (LVEF chronic renal disease (p = 0.003), more hospitalizations for acute coronary syndrome (p < 0.001), or infection (p = 0.003), and were more frequently treated with intravenous vasodilators compared to HFrEF or HFpEF. Adjusted short-term mortality in HFmrEF was lower than HFrEF [hazard ratio (HR) = 0.635 (0.419, 0.963), p = 0.033] but similar to HFpEF [HR = 1.026 (0.605, 1.741), p = 0.923]. Hospitalized HFmrEF patients represent a demographically and clinically diverse group with many intermediate features compared to HFrEF and HFpEF and carry a lower risk of short-term mortality than HFrEF but a similar risk with HFpEF.

    Objective: To explore the mid-to-long term therapeutic efficacy of Graves' disease after interventional embolization. Methods: Twenty-five patients of Graves' disease treated with interventional embolization were followed up for 24-57 months. T 3 and T 4 were monitored at pre-operation, six months, 12 months, 2, 3 and 4 years after operation, respectively. Other references included pulse, thyroid size, and vessel's murmur. Results: Twenty-two patients completely relieved from the hyperthyroidism during the follow-up. Only one patient suffered from recurrence. Other two patients were still on maintaining dosage of antithyroid drug therapy. No hypothyroidism or hypoparathyroidism was found during this term. Conclusion: Mid-to-long term follow-up showed satisfactory efficacy of interventional therapy, offering another alternative for treatment of refractory Graves' disease

    Churg-Strauss syndrome (CSS) is a rare multi-system vasculitis; some cases have been reported in Korea. The aim of this study is to describe the clinical features, treatment outcome, and long-term follow-up of CSS from a single Korean medical center. Between 1995 and 2004, seventeen patients were diagnosed with CSS at the Department of Medicine of the Samsung Medical Center, Sungkyunkwan University School of Medicine. The diagnosis of CSS is based on the classification criteria of the American Collage of Rheumatology. All patients had asthma. As in other case series, the lung, peripheral nervous system, and skin were the most commonly involved organs. During the active stage of the disease, most of the patients exhibited peripheral blood eosinophilia and an elevated serum eosinophil cationic protein level. Ten patients were treated with pulses of methylprednisolone followed by tapering and cyclophosphamide, and the others were treated with corticosteroids alone. The outcomes after long-term follow-up were generally good. One patient who was refractory to initial treatment died of heart failure during the follow-up period. CSS was highly variable in its presentation and course. The manifestations may range from mild symptoms to life-threatening conditions. The outcome after long-term follow-up was as good as that of previous studies. PMID:16614512

    Sickle cell disease is a risk factor for cerebrovascular accidents in the pediatric population. This risk is compounded by hypoxemia. Cyanotic congenital heart disease can expose patients to prolonged hypoxemia. To our knowledge, the long-term outcome of patients who have combined sickle cell and cyanotic congenital heart disease has not been reported. We retrospectively reviewed patient records at our institution and identified 5 patients (3 girls and 2 boys) who had both conditions. Their outcomes were uniformly poor: 4 died (age range, 12 mo-17 yr); 3 had documented cerebrovascular accidents; and 3 developed ventricular dysfunction. The surviving patient had developmental delays. On the basis of this series, we suggest mitigating hypoxemia, and thus the risk of stroke, in patients who have sickle cell disease and cyanotic congenital heart disease. Potential therapies include chronic blood transfusions, hydroxyurea, earlier surgical correction to reduce the duration of hypoxemia, and heart or bone marrow transplantation.

    The disease phenotype at diagnosis and the disease course of Crohn's disease (CD) and ulcerative colitis (UC) show remarkable heterogeneity across patients. This review aims to summarize the currently available evidence on clinical and some environmental predictive factors, which clinicians should evaluate in the everyday practice together with other laboratory and imaging data to prevent disease progression, enable a more personalized therapy, and avoid negative disease outcomes. In recent population-based epidemiological and referral cohort studies, the evolution of disease phenotype of CD and UC varied significantly. Most CD and severe UC patients still require hospitalization or surgery/colectomy during follow-up. A change in the natural history of inflammatory bowel diseases (IBD) with improved outcomes in parallel with tailored positioning of aggressive immunomodulator and biological therapy has been suspected. According to the currently available literature, it is of major importance to refer IBD cases at risk for adverse disease outcomes as early during the disease course as possible.

    Full Text Available Background: Parthenium dermatitis is the most common type of airborne contact dermatitis in India. It is a chronic disease of a remitting and relapsing course with significant morbidity and distress, but there is no scoring system to assess its severity. Aim: To design a scoring system for the assessment of clinical severity of disease in Parthenium dermatitis and to use this scoring system in various studies to determine its sensitivity, specificity, and reproducibility. Methods and Results: In our first few studies on Parthenium dermatitis, we designed and used a basic clinical severity scoring system based on itching, morphology of the lesions, and areas involved. However, in subsequent studies, we modified it to the present scoring system as Parthenium dermatitis severity score (PDSS. Our studies showed the high sensitivity of PDSS in characterization of the disease severity at the given point of time, as well as to determine the efficacy of a prescribed treatment modality which was reliable and reproducible. Conclusion: Thus, PDSS may be used by clinicians for appropriate scoring of the clinical severity of Parthenium dermatitis and in monitoring the disease response to therapy.

    Subtotal adrenalectomy was given to 10 adult patients with Cushing's disease, concurrently with or following therapeutic regimen by long term reserpine administration and pituitary irradiation. In the present study, we describe long term follow-up results. Two patients died after the operation due to acute adrenal crisis and pneumonia, respectively. The other 8 patients achieved clinical and biochemical remissions and were followed for long term. Three patients relapsed 9, 14 or 17 years after achieving remission, two patients developed hypopituitarism 12 or 20 years after and one died of cerebral vascular accident at 64 years, 5 years after the remission. The remaining 2 patients maintained remission for 10 or 18 years, respectively. During the remission periods of 0.5 to 20 years with a mean of 10.1±6.7 years, 6 of 7 patients examined by 1 mg overnight dexamethasone test showed normal suppressibility of plasma cortisol. Provocative tests of plasma GH by 1-arginine infusion and/or insulin-induced hypoglycemia were performed in 6 patients in the early remission period. All of 5 patients in the arginine infusion test and 3 of 5 in the insulin-induced hypoglycemia test showed normal responses. Furthermore, to facilitate prediction of long term response or failure to our therapeutic regimen, long term reserpine administration and pituitary irradiation, pretreatment clinical and biochemical characteristics were analyzed retrospectively in 3 divided groups; the present 10 patients treated with reserpine and pituitary irradiation followed by subtotal adrenalectomy, 11 patients achieving long term remission treated by our regimen alone, and 7 patients failed with our regimen alone. There were no significant factors predictive of response to our regimen. (author)

    Glycogen storage disease (GSD) is an umbrella term for a group of genetic disorders that involve the abnormal metabolism of glycogen; to date, 23 types of GSD have been identified. The nonspecific clinical presentation of GSD and the lack of specific biomarkers mean that Sanger sequencing is now widely relied on for making a diagnosis. However, this gene-by-gene sequencing technique is both laborious and costly, which is a consequence of the number of genes to be sequenced and the large size of some genes. This work reports the use of massive parallel sequencing to diagnose patients at our laboratory in Spain using either a customized gene panel (targeted exome sequencing) or the Illumina Clinical-Exome TruSight One Gene Panel (clinical exome sequencing (CES)). Sequence variants were matched against biochemical and clinical hallmarks. Pathogenic mutations were detected in 23 patients. Twenty-two mutations were recognized (mostly loss-of-function mutations), including 11 that were novel in GSD-associated genes. In addition, CES detected five patients with mutations in ALDOB, LIPA, NKX2-5, CPT2, or ANO5. Although these genes are not involved in GSD, they are associated with overlapping phenotypic characteristics such as hepatic, muscular, and cardiac dysfunction. These results show that next-generation sequencing, in combination with the detection of biochemical and clinical hallmarks, provides an accurate, high-throughput means of making genetic diagnoses of GSD and related diseases.Genet Med 18 10, 1037-1043.

    Objective The Pediatric Rheumatology International Trials Organisation (PRINTO) recently published criteria for classification of patients with juvenile dermatomyositis (DM) as having clinically inactive disease. The criteria require that at least 3 of 4 conditions be met, i.e., creatine kinase level ≤150 units/liter, Childhood Myositis Assessment Scale score ≥48, Manual Muscle Testing in 8 muscles score ≥78, and physician's global assessment of overall disease activity (PGA) ≤0.2. The present study was undertaken to test these criteria in a UK cohort of patients with juvenile DM. Methods We assessed 1,114 patient visits for the 4 items in the PRINTO criteria for clinically inactive disease. Each visit was analyzed to determine whether skin disease was present. The Disease Activity Score (DAS) for juvenile DM was determined in 59 patients. Results At 307 of the 1,114 visits, clinically inactive disease was achieved based on the 3 muscle criteria (but with a PGA of >0.2); rash was present at 65.8% of these visits and nailfold capillary abnormalities at 35.2%. When PGA ≤0.2 was one of the 3 criteria that were met, the frequency of skin signs was significantly lower (rash in 23.1% and nailfold capillary abnormalities in 8.7%). If PGA was considered an essential criterion for clinically inactive disease (P‐CID), patients with active skin disease were less likely to be categorized as having clinically inactive disease (a median DAS skin score of 0 [of a possible maximum of 9] in visits where the PGA was ≤0.2, versus a median DAS skin score of 4 in patients meeting the 3 muscle criteria [with a PGA of >0.2]; P < 0.001). Use of the P‐CID led to improvements in the positive predictive value and the positive likelihood ratio (85.4% and 11.0, respectively, compared to 72.9% and 5.1 with the current criteria). Conclusion There was a high frequency of skin disease among patients with juvenile DM who did not meet the PGA criterion for inactive disease but met

    Full Text Available Anderson-Fabry disease (AFD is an Xlinked lysosomal storage disorder of glycosphingolipid catabolism, due to deficiency or absence of a galactosidase A (α-gal A enzyme. The disease may affect males and females, the latter with an average 10 years delay. Metabolites storage (mostly Gb3 and lyso-Gb3 leads to progressive cellular and multiorgan dysfunction, with either early and late onset variable clinical manifestations that usually reduce quality of life and life expectancy. Heart and kidney failure, stroke and sudden death are the most devastating complications. AFD is always been considered a very rare disease, although new epidemiologic data, based on newborn screening, showed that AFD prevalence is probably underestimated and much higher than previously reported, especially for late-onset atypical phenotypes. Currently, the diagnosis may be easier and simpler by evaluating α-gal A enzyme activity and genetic analysis for GLA gene mutations on dried blood spot. While a marked α-gal A deficiency leads to diagnosis of AFD in hemizygous males, the molecular analysis is mandatory in heterozygous females. However, referral to a center with an expert multidisciplinary team is highly advisable, in order to ensure careful management and treatment of patients, based also on accurate molecular and biochemical data interpretation. While long-term efficacy of enzyme replacement therapy (ERT in advanced stage is still debated, increasing evidence shows greater efficacy of early treatment initiation. Concomitant, organ-specific therapy is also needed. New treatment approaches, such as chemical chaperone therapy, alone or in combination with ERT, are currently under investigation. The present review illustrates the major features of the disease, focusing also on biochemical and genetic aspects.

    2010-02-01

    A minimum 4-point change at 6 months on the Alzheimer's disease assessment scale-cognitive subscale (ADAS-cog) is deemed clinically important, but this cut-point has been little studied in relation to clinical meaningfulness. In an investigator-initiated, clinical trial of galantamine, we investigated the extent to which a 4-point change classifies goal attainment by individual patients. Secondary analysis of the video imaging synthesis of treating Alzheimer's disease (VISTA) study: a 4-month, multi-centre, parallel-group, double-blind, placebo-controlled, trial of galantamine in 130 mild-moderate Alzheimer's disease patients (4-month open-label follow-up). ADAS-cog responses at 6 months were compared with outcomes on three clinical measures: clinician's interview based impression of change-plus caregiver input (CIBIC+), patient/carer-goal attainment scaling (PGAS) and clinician-GAS (CGAS). Thirty-seven of 99 patients improved by > or = 4 points on the ADAS-cog at 6 months, and 16/99 showed > or = 4-point worsening. ADAS-cog change scores correlated notionally to modestly with changes on the CGAS (r = -0.31), the PGAS (r = -0.29) and the CIBIC+ (r = 0.31). As a group, patients with ADAS-cog improvement were significantly more likely to improve on the clinical measures; those who worsened showed non-significant clinical decline. Individually, about half were misclassified in relation to each clinical measure; often when the ADAS-Cog detected 'no change', clinically meaningful effects could be detected. Even so, no ADAS-Cog cut-point optimally classified patients' clinical responses. A 4-point ADAS-cog change at 6 months is clinically meaningful for groups. Substantial individual misclassification between the ADAS-cog and clinical measures suggests no inherent meaning to a 4-point ADAS-cog change for a given patient.

    Canavan disease is a rare hereditary leukodystrophy that manifests in early childhood. Associated with rapidly progressive clinical deterioration, it usually results in death by the third year of life. The predominant MRI appearance is diffuse and symmetrical white matter disease. We discuss an atypical, late presentation of Canavan disease with a benign clinical course and uncharacteristic imaging features. This case introduces a previously unreported pattern of diffuse cortical abnormality without significant white matter involvement. (orig.)

    Full Text Available The course and outcome of a disease process is dependent upon factors such as the disease-causing agent and its cell tropism, defense mechanisms of the host, genetic resistance of the species or breed affected, as well as the age, nutritional status and hormonal levels of the affected animal. When haematology, clinical biochemistry and cytology test results are combined with other laboratory procedures, complete physical examination and also with the history of the patient, a veterinarian is well armed to arrive at a definitive diagnosis, make a certain prognosis (good, poor or guarded and can also make a concluding statement on the efficacy of the instituted therapy. In clinical biochemistry, demonstration of specific enzyme activity and concentration of analytes in serum/plasma facilitates the disease diagnosis. Also, evaluation of haematology, clinical biochemistry and diagnostic cytology tests can help establish the presence or absence of diseases of internal organs, and by serial performance of these tests, may help to determine whether a disease process remains static, progressive or regressive. This review therefore provides the haematological, serum biochemical and cytological characteristics of diseases caused by the main bacteria, viruses, fungi, protozoa, helminths, arthropods, nutritional deficiencies, endocrine disturbances, neoplasm, allergy, toxins (phytoxins and zootoxins and inorganic poisons in horses.

    Clinical business intelligence tools such as clinical data warehouse enable health care organizations to objectively assess the disease management programs that affect the quality of patients' life and well-being in public. The purpose of these programs is to reduce disease occurrence, improve patient care, and decrease health care costs. Therefore, applying clinical data warehouse can be effective in generating useful information about aspects of patient care to facilitate budgeting, planning, research, process improvement, external reporting, benchmarking, and trend analysis, as well as to enable the decisions needed to prevent the progression or appearance of the illness aligning with maintaining the health of the population. The aim of this review article is to describe the benefits of clinical data warehouse applications in creating intelligence for disease management programs.

    Full Text Available ABSTRACT Objective: to perform a cross-term mapping of nursing language in the patient record with the Nursing Interventions Classification system, in rehabilitation patients with Parkinson's disease. Method: a documentary research study to perform cross mapping. A probabilistic, simple random sample composed of 67 records of patients with Parkinson's disease who participated in a rehabilitation program, between March of 2009 and April of 2013. The research was conducted in three stages, in which the nursing terms were mapped to natural language and crossed with the Nursing Interventions Classification. Results: a total of 1,077 standard interventions that, after crossing with the taxonomy and refinement performed by the experts, resulted in 32 interventions equivalent to the Nursing Interventions Classification (NIC system. The NICs, "Education: The process of the disease.", "Contract with the patient", and "Facilitation of Learning" were present in 100% of the records. For these interventions, 40 activities were described, representing 13 activities by intervention. Conclusion: the cross mapping allowed for the identification of corresponding terms with the nursing interventions used every day in rehabilitation nursing, and compared them to the Nursing Interventions Classification.

    Objective: The goal of this study was to characterize the parkinsonian phenotype in patients with Gaucher disease (GD) who developed parkinsonism in order to evaluate clinical course and prognosis. Methods: This is a retrospective observational study conducted at the Clinical Center of the NIH, Bethesda, MD, over a period of 10 years. The study included 19 patients with GD and parkinsonism. The severity of Gaucher and parkinsonian symptoms was determined from clinical data including physical, neurologic, pathologic, and neurocognitive evaluations, family histories, imaging studies, olfactory testing, and validated questionnaires. Results: We found an earlier age at onset of parkinsonism and evidence of mild cognitive dysfunction in our cohort. Although the clinical course in some patients was similar to that of idiopathic Parkinson disease with a favorable levodopa response, others exhibited features characteristic of dementia with Lewy bodies. When we examined the patients as a group, we did not observe a uniformly aggressive form of parkinsonism after the initial onset of symptoms, contrary to other published reports. Conclusions: Appreciable clinical variation was seen in this cohort with GD and parkinsonism. Although some patients had early onset and prominent cognitive changes, others had a later, slower course, indicating that GBA1 mutations may not be a reliable prognostic indicator in Parkinson disease in clinical settings.

    Individuals with REM sleep behaviour disorder are at significantly higher risk of developing Parkinson's disease. Here we examined visual short-term memory deficits--long associated with Parkinson's disease--in patients with REM sleep behaviour disorder without Parkinson's disease using a novel task that measures recall precision. Visual short-term memory for sequentially presented coloured bars of different orientation was assessed in 21 patients with polysomnography-proven idiopathic REM sleep behaviour disorder, 26 cases with early Parkinson's disease and 26 healthy controls. Three tasks using the same stimuli controlled for attentional filtering ability, sensorimotor and temporal decay factors. Both patients with REM sleep behaviour disorder and Parkinson's disease demonstrated a deficit in visual short-term memory, with recall precision significantly worse than in healthy controls with no deficit observed in any of the control tasks. Importantly, the pattern of memory deficit in both patient groups was specifically explained by an increase in random responses. These results demonstrate that it is possible to detect the signature of memory impairment associated with Parkinson's disease in individuals with REM sleep behaviour disorder, a condition associated with a high risk of developing Parkinson's disease. The pattern of visual short-term memory deficit potentially provides a cognitive marker of 'prodromal' Parkinson's disease that might be useful in tracking disease progression and for disease-modifying intervention trials. © The Author (2015).

    Individuals with mutation in the lysosomal enzyme glucocerebrosidase (GBA) gene are at significantly high risk of developing Parkinson's disease with cognitive deficit. We examined whether visual short-term memory impairments, long associated with patients with Parkinson's disease, are also present in GBA-positive individuals-both with and without Parkinson's disease. Precision of visual working memory was measured using a serial order task in which participants observed four bars, each of a different colour and orientation, presented sequentially at screen centre. Afterwards, they were asked to adjust a coloured probe bar's orientation to match the orientation of the bar of the same colour in the sequence. An additional attentional 'filtering' condition tested patients' ability to selectively encode one of the four bars while ignoring the others. A sensorimotor task using the same stimuli controlled for perceptual and motor factors. There was a significant deficit in memory precision in GBA-positive individuals-with or without Parkinson's disease-as well as GBA-negative patients with Parkinson's disease, compared to healthy controls. Worst recall was observed in GBA-positive cases with Parkinson's disease. Although all groups were impaired in visual short-term memory, there was a double dissociation between sources of error associated with GBA mutation and Parkinson's disease. The deficit observed in GBA-positive individuals, regardless of whether they had Parkinson's disease, was explained by a systematic increase in interference from features of other items in memory: misbinding errors. In contrast, impairments in patients with Parkinson's disease, regardless of GBA status, was explained by increased random responses. Individuals who were GBA-positive and also had Parkinson's disease suffered from both types of error, demonstrating the worst performance. These findings provide evidence for dissociable signature deficits within the domain of visual short-term

    Encephalopathy associated with autoimmune thyroid disease is a rare condition presenting in the setting of autoimmune thyroid disease and characterized by unspecific neurological and\\/or psychiatric symptoms. Bearing in mind the currently prevailing lack of consensus on the most appropriate nomenclature and diagnostic criteria for this condition and the implications that this lack undeniably has on clinical practice, it is obvious that an international and multidisciplinary agreement among clinicians should arrive at the most appropriate definition and terminology of encephalopathy occurring in patients with autoimmune thyroid disease. Concomitantly, efforts must be made to uncover the pathogenetic link between thyroid autoimmunity and the occurrence of encephalopathy.

    The aim of this study was to assess our clinical experience with infliximab, a monoclonal antitumor necrosis factor antibody, following its approval for treatment of refractory Crohn's disease (CD). We followed 100 consecutive patients with CD (53 women and 47 men; mean age, 41 yr) who received a total of 233 infliximab (5 mg/kg) infusions. Adverse events were noted and clinical response assessed every 2 wk for 6 months after each infusion using the Harvey Bradshaw Index (HBI) for active disease, the Perianal Disease Activity Index (PDAI) for fistulous disease, and steroid withdrawal rates for steroid-sparing efficacy. Indications for therapy were active disease (n = 57), perianal fistulous disease (n = 33), and steroid dependency (n = 10). Significant infusion reactions occurred in 16 patients (6.9% of infusions) including anaphylactic shock in one patient. Fourteen patients experienced infectious adverse events, 13 of whom were on concurrent steroids. Sixty percent of patients with active disease experienced > or = 50% HBI reduction at 2 wk; mean duration of response, 8.2 wk. Three of 26 first-time nonresponders with active disease (12%) responded to a second infusion. Sixty-nine percent of patients with fistulous disease experienced >50% reduction in their PDAI at 2 wk; mean duration of response, 10.9 wk. Four of 10 steroid-dependent patients (40%) discontinued steroid therapy, one of whom recommenced steroid therapy at 24 wk. Our clinical response rates mirror the efficacy reported in the controlled trials for active and fistulous disease. Steroid-sparing efficacy was seen in 40% of steroid-dependent patients. Concurrent steroids did not reduce the risk of significant infusion reactions (6.9%), but did increase the risk of infections.

    Biosimilar infliximab CT-P13 received European Medicines Agency [EMA] approval in June 2013 for all indications of the originator product. In the present study, we aimed to evaluate the predictors of short- and medium-term clinical outcome in patients treated with the biosimilar infliximab at the participating inflammatory bowel disease [IBD] centres in Hungary. Demographic data were collected and a harmonised monitoring strategy was applied. Clinical and biochemical activities were evaluated at Weeks 14, 30, and 54. Trough level [TL] and anti-drug antibody [ADA] concentrations were measured by enzyme-linked immunosorbent assay [ELISA] [LT-005, Theradiag, France] at baseline at 14, 30 and 54 weeks and in two centres at Weeks 2 and 6. A total of 291 consecutive IBD patients (184 Crohn's disease [CD] and 107 ulcerative colitis [UC]) were included. In UC, TLs at Week 2 predicted both clinical response and remission at Weeks 14 and 30 (clinical response/remission at Week 14: area under the curve [AUC] = 0.81, p < 0.001, cut-off: 11.5 μg/ml/AUC = 0.79, p < 0.001, cut-off: 15.3μg/ml; clinical response/remission at Week 30: AUC = 0.79, p = 0.002, cut-off: 11.5 μg/ml/AUC = 0.74, p = 0.006, cut-off: 14.5 μg/ml), whereas ADA positivity at Week 14 was inversely associated with clinical response at Week 30 [58.3% vs 84.8% ,p = 0.04]. Previous anti-tumour necrosis factor [TNF] exposure was inversely associated with short-term clinical remission [Week 2: 18.8% vs 47.8%, p = 0.03, at Week 6: 38.9% vs 69.7%, p = 0.013, at Week 14: 37.5% vs 2.5%, p = 0.06]. In CD, TLs at Week 2 predicted short-term [Week 14 response/remission, AUCTLweek2 = 0.715-0.721, p = 0.05/0.005] but not medium-term clinical efficacy. In addition, early ADA status by Week 14 [p = 0.04-0.05 for Weeks 14 and 30], early clinical response [p < 0.001 for Weeks 30/54] and normal C-reactive protein [CRP] at Week 14 [p = 0.005-0.0001] and previous anti-TNF exposure [p = 0.03-0.0001 for Weeks 14, 30, and 54] were

    A study group of 30 individuals was randomly chosen from 1,379 beneficiaries predicted to be at risk for health care complications at a large, Midwest, industrial company currently experiencing increased health care costs. All 30 individuals had one or more chronic illness, primarily diabetes, cardiovascular disease, or asthma. Through analysis of medical records, a self-reporting health risk assessment survey, and personal contact with both patients and clinicians, each study individual was assessed as to whether his disease(s) was under control, the individual was compliant with his treatment protocol, and whether the supervising clinician was following nationally accepted standards of care. Fewer than 50% of the individuals in the study group had their chronic illness(es) under control. Those individuals whose treatment adhered to national guidelines were significantly more likely to have their disease under control (p Behavioral (external) barriers were most often cited as the reason a clinical practitioner did not follow the appropriate national standard of care. Most clinicians were aware of and familiar with the guidelines; a few either did not agree with or misunderstood the guidelines. The results of this study suggest that changing clinical practice behaviors to better ensure compliance to national standards of care may make a substantial difference in chronic disease control.

    Full Text Available Virtually all human disease is induced by oxidative stress. Oxidative stress, which is caused by toxic environmental exposure, the presence of disease, lifestyle choices, stress, chronic inflammation or combinations of these, is responsible for most disease. Oxidative stress from all sources is additive and it is the total oxidative stress from all sources that induces the onset of most disease. Oxidative stress leads to lipid peroxidation, which in turn produces Malondialdehyde. Serum malondialdehyde level is an additive parameter resulting from all sources of oxidative stress and, therefore, is a reliable indicator of total oxidative stress which can be used to predict the onset of disease in clinically asymptomatic individuals and to suggest the need for treatment that can prevent much human disease.

    The measurement of leukocyte rheology in vascular disease is a recent development with a wide range of new opportunities. The International Society of Clinical Hemorheology has asked an expert panel to propose guidelines for the investigation of leukocyte rheology in clinical situations. This article first discusses the mechanical, adhesive and related functional properties of leukocytes (especially neutrophils) which influence their circulation, and establishes the rationale for clinically-related measurements of parameters which describe them. It is concluded that quantitation of leukocyte adhesion molecules, and of their endothelial receptors may assist understanding of leukocyte behaviour in vascular disease, along with measurements of flow resistance of leukocytes, free radical production, degranulation and gene expression. For instance, vascular cell adhesion molecule (VCAM-1) is abnormally present on endothelial cells in atherosclerosis, diabetes mellitus and inflammatory conditions. Soluble forms of intercellular adhesion molecule (ICAM-1) or VCAM can be found elevated in the blood of patients with rheumatoid arthritis or infections disease. In the second part of the article, possible technical approaches are presented and possible avenues for leukocyte rheological investigations are discussed.

However, there remains a pressing demand for alternative therapeutic options for patients with primary nonresponse, secondary loss of response, or intolerable side effects to conventional treatment and TNF antagonists. Ustekinumab (UST is a fully human IgG1κ monoclonal antibody that inhibits the p40 subunit shared by the proinflammatory cytokines, the interleukin (IL-12 and -23. This blockade leads to dampening of the inflammatory cascade and differentiation of inflammatory T cells. The clinical development program for UST in CD includes dose finding Phase II (Crohn’s Evaluation of Response to Ustekinumab Anti-Interleukin-12/23 for Induction [CERTIFI] and the pivotal Phase III (UNITI trials that demonstrated both the clinical efficacy and safety in anti-TNF-naive and anti-TNF-exposed patients. Real-world evidence has further defined the role of UST in CD management. In this review, we discuss the mechanism of action of UST, describe the results of the randomized controlled trials with this agent, and review the real-world efficacy and safety data from observational cohorts. Finally, we identify areas of future research in the IL-12/23 inflammatory pathway and discuss the positioning of this novel therapeutic option in CD treatment algorithms.

    Nonalcoholic fatty liver disease (NAFLD) is defined as the presence of hepatic fat accumulation after the exclusion of other causes of hepatic steatosis, including other causes of liver disease, excessive alcohol consumption, and other conditions that may lead to hepatic steatosis. NAFLD encompasses a broad clinical spectrum ranging from nonalcoholic fatty liver to nonalcoholic steatohepatitis (NASH), advanced fibrosis, cirrhosis, and finally hepatocellular carcinoma (HCC). NAFLD is the most common liver disease in the world and NASH may soon become the most common indication for liver transplantation. Ongoing persistence of obesity with increasing rate of diabetes will increase the prevalence of NAFLD, and as this population ages, many will develop cirrhosis and end-stage liver disease. There has been a general increase in the prevalence of NAFLD, with Asia leading the rise, yet the United States is following closely behind with a rising prevalence from 15% in 2005 to 25% within 5 years. NAFLD is commonly associated with metabolic comorbidities, including obesity, type II diabetes, dyslipidemia, and metabolic syndrome. Our understanding of the pathophysiology of NAFLD is constantly evolving. Based on NAFLD subtypes, it has the potential to progress into advanced fibrosis, end-stage liver disease and HCC. The increasing prevalence of NAFLD with advanced fibrosis, is concerning because patients appear to experience higher liver-related and non-liver-related mortality than the general population. The increased morbidity and mortality, healthcare costs and declining health related quality of life associated with NAFLD makes it a formidable disease, and one that requires more in-depth analysis.

It is characterized clinically by the classic triad that associated tremors, bradykinesia, and rigidity. In Niger, there are no data on PD. Aims: We aimed to provide the demographic and clinical profile of PD in patients from Niger to create a database on PD in Niger. Patients and Methods: We conducted a retrospective study at the Neurology Outpatient Clinic of the Hôpital National de Niamey (HNN, Niger over a period of 4.42 years from February 2009 to July 2013 collecting all cases of PD. The demographic and clinical features of all patients were collected and analyzed. Results: During the period of the study, 1695 patients consulted at the Neurology Outpatient Clinic of the HNN, among which 76 patients (4.48% had secondary parkinsonism and 25 patients (1.47% had features compatible with PD. Only patients with PD were included in this study. The mean age at onset of symptoms was 58 years (range: 42–74 years. The male sex was predominant (60% with a sex ratio of 1.5. The mean time interval from the onset of symptoms to diagnosis of PD was 1.8 years (range: 1–5 years. The tremor was the most common symptom (84%. Bradykinesia represented 64% of the symptoms and rigidity 20%. At the time of the diagnosis of PD, 8 patients (32% were in Stage I of the classification of Hoehn and Yahr, 16 patients (64% in Stage II, and 1 patient (4% in Stage III. The levodopa/carbidopa combination was the most used antiparkinsonian drug in our patients (88%. The mean time of follow-up of the patients was 2.5 years (range: 1–4.42 years.

    This article describes the use of smart technology by investigators and patients to facilitate lung disease clinical trials and make them less costly and more efficient. By "smart technology" we include various electronic media, such as computer databases, the Internet, and mobile devices. We first describe the use of electronic health records for identifying potential subjects and then discuss electronic informed consent. We give several examples of using the Internet and mobile technology in clinical trials. Interventions have been delivered via the World Wide Web or via mobile devices, and both have been used to collect outcome data. We discuss examples of new electronic devices that recently have been introduced to collect health data. While use of smart technology in clinical trials is an exciting development, comparison with similar interventions applied in a conventional manner is still in its infancy. We discuss advantages and disadvantages of using this omnipresent, powerful tool in clinical trials, as well as directions for future research. Published by Elsevier Inc.

    Short-term memory binding of visual features which are processed across different dimensions (shape-colour) is impaired in sporadic Alzheimer's disease, familial Alzheimer's disease, and in asymptomatic carriers of familial Alzheimer's disease. This study investigated whether Alzheimer's disease also impacts on within-dimension binding processes. The study specifically explored whether visual short-term memory binding of features of the same type (colour-colour) is sensitive to Alzheimer's disease. We used a neuropsychological battery and a short-term memory binding task to assess patients with sporadic Alzheimer's disease (Experiment 1), familial Alzheimer's disease (Experiment 2) due to the mutation E280A of the Presenilin-1 gene and asymptomatic carriers of the mutation. The binding task assessed change detection within arrays of unicoloured objects (Colour Only) or bicoloured objects the colours of which had to be remembered separately (Unbound Colours) or together (Bound Colours). Performance on the Bound Colours condition (1) explained the largest proportion of variance between patients (sporadic and familial Alzheimer's disease), (2) combined more sensitivity and specificity for the disease than other more traditional neuropsychological tasks, (3) identified asymptomatic carriers of the mutation even when traditional neuropsychological measures and other measures of short-term memory did not and, (4) contrary to shape-colour binding, correlated with measures of hippocampal functions. Colour-colour binding and shape-colour binding both appear to be sensitive to AD even though they seem to rely on different brain mechanisms. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2011-03-01

    Punding (the display of stereotyped, repetitive behaviors) is a relatively recently discovered feature of Parkinson's disease (PD). Little is known about the prevalence and clinical characteristics of punding in PD. In this review, four large scientific databases were comprehensively searched for literature in relation to punding prevalence and clinical correlates in the context of PD. Prevalence was found to vary greatly (between 0.34 to 14%), although there were large disparities in study populations, assessment methods, and criteria. We observed an association between punding, dopaminergic medications, and impulse control disorder. Other characteristics, which may be more common among punders, include a higher severity of dyskinesia, younger age of disease onset, longer disease duration, and male gender. More research in large clinical datasets is required in many areas before conclusions are drawn. The pathophysiology behind the punding phenomenon is also poorly understood at present, rendering it difficult to develop targeted therapy. The current mainstay of treatment is the reduction in the dose of dopaminergic medications, the evidence for other suggested therapies being purely empirical.

However, the case criteria of ME and CFS define two distinct clinical entities. Although some patients will meet both case criteria, other patients can meet the diagnosis of ME and not fulfil the case criteria for CFS, while the diagnosis of CFS is largely insufficient to be qualified as a ME patient. ME is a neuromuscular disease with distinctive muscular symptoms, including prolonged muscle weakness after exertion, and neurological signs implicating cerebral dysfunction, including cognitive impairment and sensory symptoms. The only mandatory symptom of CFS is chronic fatigue. Chronic fatigue must be accompanied by at least four out of eight nonspecific symptoms: substantial impairment in short-term memory or concentration, a sore throat, tender lymph nodes, muscle pain, multijoint pain, a new type of headaches, unrefreshing sleep, and postexertional “malaise” lasting more than 24 h. So, regardless whether the name ME is appropriate or not, ME is not synonymous to CFS. That is not a matter of opinion, but a matter of definition. Due to the definitions of ME and CFS, “ME/CFS” does not exist and cannot be replaced by a new clinical entity (SEID: Systemic Exertion Intolerance Disease, as recently suggested.

    Tissue oxygenation is a critical parameter in various pathophysiological situations including cardiovascular disease and cancer. Hypoxia can significantly influence the prognosis of solid malignancies and the efficacy of their treatment by radiation or chemotherapy. Electron paramagnetic resonance (EPR) oximetry is a reliable method for repeatedly assessing and monitoring oxygen levels in tissues. Lithium octa-n-butoxynaphthalocyanine (LiNc-BuO) has been developed as a probe for biological EPR oximetry, especially for clinical use. However, clinical applicability of LiNc-BuO crystals is hampered by potential limitations associated with biocompatibility, biodegradation, or migration of individual bare crystals in tissue. To overcome these limitations, we have embedded LiNc-BuO crystals in polydimethylsiloxane (PDMS), an oxygen-permeable biocompatible polymer and developed an implantable/retrievable form of chip, called OxyChip. The chip was optimized for maximum spin density (40% w/w of LiNc-BuO in PDMS) and fabricated in a form suitable for implantation using an 18-G syringe needle. In vitro evaluation of the OxyChip showed that it is robust and highly oxygen sensitive. The dependence of its EPR linewidth to oxygen was linear and highly reproducible. In vivo efficacy of the OxyChip was evaluated by implanting it in rat femoris muscle and following its response to tissue oxygenation for up to 12 months. The results revealed preservation of the integrity (size and shape) and calibration (oxygen sensitivity) of the OxyChip throughout the implantation period. Further, no inflammatory or adverse reaction around the implantation area was observed thereby establishing its biocompatibility and safety. Overall, the results demonstrated that the newly-fabricated high-sensitive OxyChip is capable of providing long-term measurements of oxygen concentration in a reliable and repeated manner under clinical conditions.

    Assessing cognitive and functional changes at the early stage of Alzheimer's disease (AD) and detecting treatment effects in clinical trials for early AD are challenging. Under the assumption that transformed versions of the Mini-Mental State Examination, the Clinical Dementia Rating Scale-Sum of Boxes, and the Alzheimer's Disease Assessment Scale-Cognitive Subscale tests'/components' scores are from a multivariate linear mixed-effects model, we calculated the sample sizes required to detect treatment effects on the annual rates of change in these three components in clinical trials for participants with mild cognitive impairment. Our results suggest that a large number of participants would be required to detect a clinically meaningful treatment effect in a population with preclinical or prodromal Alzheimer's disease. We found that the transformed Mini-Mental State Examination is more sensitive for detecting treatment effects in early AD than the transformed Clinical Dementia Rating Scale-Sum of Boxes and Alzheimer's Disease Assessment Scale-Cognitive Subscale. The use of optimal weights to construct powerful test statistics or sensitive composite scores/endpoints can reduce the required sample sizes needed for clinical trials. Consideration of the multivariate/joint distribution of components' scores rather than the distribution of a single composite score when designing clinical trials can lead to an increase in power and reduced sample sizes for detecting treatment effects in clinical trials for early AD.

    Background The definitions that are being used for the terms 'clinical pharmacy' and 'pharmaceutical care' seem to have a certain overlap. Responsibility for therapy outcomes seems to be especially linked to the latter term. Both terms need clarification before a proper definition of clinical pharmacy can be drafted. Objective To identify current disagreements regarding the term 'Clinical Pharmacy' and its relationship to 'Pharmaceutical Care' and to assess to which extent pharmacists with an interest in Clinical Pharmacy are willing to accept responsibility for drug therapy outcomes. Setting The membership of the European Society of Clinical Pharmacy. Methods A total of 1,285 individuals affiliated with the European Society of Clinical Pharmacy were invited by email to participate in an online survey asking participants to state whether certain professional activities, providers, settings, aims and general descriptors constituted (a) 'Clinical Pharmacy only', (b) 'Pharmaceutical Care only', (c) 'both' or (d) 'neither'. Further questions examined pharmacists' willingness to accept ethical or legal responsibility for drug therapy outcomes, under current and ideal working conditions. Main outcome measures Level of agreement with a number of statements. Results There was disagreement (responsibility under current/ideal working conditions were: safety (32.7%/64.3%), effectiveness (17.9%/49.2%), patient-centeredness (17.1%/46.2%), cost-effectiveness (20.3%/44.0%). Conclusions The survey identified key disagreements around the term 'Clinical Pharmacy' and its relationship to 'Pharmaceutical Care', which future discussions around a harmonised definition of 'Clinical Pharmacy' should aim to resolve. Further research is required to understand barriers and facilitators to pharmacists accepting responsibility for drug therapy outcomes.

    This study was done to determine various causes and clinical presentation of heart disease in children. It was a prospective hospital study conducted in Department of Pediatrics Civil Hospital, Karachi from August 1995 to February 1996. In this study, 70 patients of heart disease upto 12 years of age were inducted. There were 33 (47.14%) cases of congenital heart diseases and 37 (52.85%) cases of acquired heart diseases. The age distribution showed that heart disease was more frequent between 0-11 months of age (41.42%). Congenital heart diseases were also frequent between 0-11 months (28.57%). On the other hand acquired heart diseases were more common between 6-12 years (22.85%). In this study the males were predominantly involved, the male to female ratio was 1.05:1. In congenital heart disease it was 1.3:1 and in acquired heart diseases it was 0.85:1. Ventricular septal defect was the commonest congenital lesion reported (20%). Rheumatic fever and viral myocarditis were two frequently occurring acquired heart-diseases 17.14% each. The common presentation of heart diseases were respiratory distress (94.28%), fever (90%), feeding difficulty (57.14%) and failure to thrive (34.28%). In case of rheumatic fever, chorea was present in 8.57%, arthritis in 11.42% and S/C nodules (2.85%) cases respectively. The early management of the problem may help in decreasing morbidity and mortality due to these disease in children. Prenatal detection of congenital cardiac lesions by fetal echocardiography in high risk pregnancies, early intervention in neonatal period and counseling of the parents may help in prevention of congenital heart diseases in children. Primary prevention of rheumatic fever can be achieved by early diagnosis and treatment of streptococcal throat infection. (author)

    Stargardt disease (STGD1; MIM 248200) is the most prevalent inherited macular dystrophy and is associated with disease-causing sequence variants in the gene ABCA4. Significant advances have been made over the last 10 years in our understanding of both the clinical and molecular features of STGD1, and also the underlying pathophysiology, which has culminated in ongoing and planned human clinical trials of novel therapies. The aims of this review are to describe the detailed phenotypic and genotypic characteristics of the disease, conventional and novel imaging findings, current knowledge of animal models and pathogenesis, and the multiple avenues of intervention being explored.

    The vertebral artery lesion has a variety of clinical characteristics. We sought to clarify the clinical patterns and the location of the intracranial vertebral artery (ICVA) diseases according to analyses of images obtained using magnetic resonance angiography (MRA). We studied vascular lesions, risk factors, symptoms, signs, and outcomes in 35 patients with ICVA disease (3 had bilateral occlusion; 9, unilateral occlusion; 6, bilateral stenosis; and 17, unilateral stenosis). The most common site of unilateral and bilateral lesions was the distal ICVA after the origin of posterior inferior cerebellar artery (PICA). We found accompanying basilar artery disease in 28.6% of patients with unilateral and bilateral ICVA disease. The majority of the ICVA lesions were associated with internal carotid arteries disease (48.8%). The common vascular risk factors were hypertension (71%), diabetes mellitus (34%), hyperlipidemia (31%), smoking (29%), and coronary artery disease (23%). Eighteen patients (51.4%) had transient ischemic attacks (TIAs) only, 10 patients (28.6%) had TIAs before stroke, and 5 patients (14.3%) had strokes without TIAs. Most patients (80%) with TIAs, with or without stroke, had multiple episodes. Vertigo or dizziness, ataxia, limbs weakness and abnormal gait were the common symptoms and signs. At 6 months follow-up, 66.7% patients had no symptoms or only slight symptoms that caused no disability. Our data showed (1) the usual location of ICVA disease (occlusion or severe stenosis) was distal to PICA, especially near the vertebrobasilar junction; (2) the risk factors were hypertension, diabetes mellitus, hyperlipidemia, smoking, and coronary artery disease; (3) patients with ICVA disease had a high frequency of accompanying internal carotid, middle cerebral, or basilar artery disease; (4) vertigo or dizziness, and ataxia were the common symptoms and signs; (5) TIA was the most common clinical pattern; (6) the outcome was favorable, except in cases with

    Full Text Available Patients with large artery intracranial occlusive disease (LAICOD are at risk for both acute ischemia and chronic hypoperfusion. Collateral circulation plays an important role in prognosis, and imaging plays an essential role in diagnosis, treatment planning, and prognosis of patients with LAICOD. In addition to standard structural imaging, assessment of cerebral hemodynamic function is important to determine the adequacy of collateral supply. Among the currently available methods of assessment of cerebral hemodynamic function, measurement of cerebrovascular reactivity (CVR using blood oxygen level-dependent (BOLD MRI and precisely controlled CO2 has shown to be a safe, reliable, reproducible, and clinically useful method for long-term assessment of patients. Here, we report a case of long-term follow-up in a 28-year-old Caucasian female presented to the neurology clinic with a history of TIAs and LAICOD of the right middle cerebral artery (MCA. Initial structural MRI showed a right MCA stenosis and a small right coronal radiate lacunar infarct. Her CVR study showed a large area of impaired CVR with a paradoxical decrease in BOLD signal with hypercapnia involving the right MCA territory indicating intracerebral steal. The patient was managed medically with anticoagulant and antiplatelet therapy and was followed-up for over 9 years with both structural and functional imaging. Cortical thickness (CT measures were longitudinally assessed from a region of interest that was applied to subsequent time points in the cortical region exhibiting steal physiology and in the same region of the contralateral healthy hemisphere. In the long-term follow-up, the patient exhibited improvement in her CVR as demonstrated by the development of collaterals with negligible changes to CT. Management of patients with LAICOD remains challenging since no revascularization strategies have shown efficacy except in patients with moyamoya disease. Management is well

    Parkinson disease (PD) is a progressive, debilitating neurodegenerative disease that often requires complex pharmacologic treatment regimens. Prior to this clinic, there was no involvement of a clinical pharmacy specialist (CPS) in the outpatient neurology clinic at the West Palm Beach Veterans Affairs Medical Center. This was a prospective, quality-improvement project to develop a clinical pharmacist-run neurology telephone clinic and evaluate pharmacologic and nonpharmacologic interventions in an effort to improve the quality of care for patients with PD. Additionally, the CPS conducted medication education groups to 24 patients with PD and their caregivers, if applicable, at this medical center with the purpose of promoting patient knowledge and medication awareness. Medication management was performed via telephone rather than face to face. Only patients with a concomitant mental health diagnosis for which they were receiving at least one psychotropic medication were included for individual visits due to the established scope of practice of the CPS being limited to mental health and primary care medications. Data collection included patient and clinic demographics as well as pharmacologic and nonpharmacologic interventions made for patients enrolled from January 6, 2017, through March 31, 2017. A total of 49 pharmacologic and nonpharmacologic interventions were made for 10 patients. We successfully implemented and evaluated a clinical pharmacist-run neurology telephone clinic for patients with PD. Expansion of this clinic to patients with various neurological disorders may improve access to care using an innovative method of medication management expertise by a CPS.

    Background: The seed powder of the leguminous plant, Mucuna pruriens has long been used in traditional Ayurvedic Indian medicine for diseases including parkinsonism. We have assessed the clinical effects and levodopa (L-dopa) pharmacokinetics following two different doses of mucuna preparation and compared them with standard L-dopa/carbidopa (LD/CD). Methods: Eight Parkinson's disease patients with a short duration L-dopa response and on period dyskinesias completed a randomised, controlled, double blind crossover trial. Patients were challenged with single doses of 200/50 mg LD/CD, and 15 and 30 g of mucuna preparation in randomised order at weekly intervals. L-Dopa pharmacokinetics were determined, and Unified Parkinson's Disease Rating Scale and tapping speed were obtained at baseline and repeatedly during the 4 h following drug ingestion. Dyskinesias were assessed using modified AIMS and Goetz scales. Results: Compared with standard LD/CD, the 30 g mucuna preparation led to a considerably faster onset of effect (34.6 v 68.5 min; p = 0.021), reflected in shorter latencies to peak L-dopa plasma concentrations. Mean on time was 21.9% (37 min) longer with 30 g mucuna than with LD/CD (p = 0.021); peak L-dopa plasma concentrations were 110% higher and the area under the plasma concentration v time curve (area under curve) was 165.3% larger (p = 0.012). No significant differences in dyskinesias or tolerability occurred. Conclusions: The rapid onset of action and longer on time without concomitant increase in dyskinesias on mucuna seed powder formulation suggest that this natural source of L-dopa might possess advantages over conventional L-dopa preparations in the long term management of PD. Assessment of long term efficacy and tolerability in a randomised, controlled study is warranted. PMID:15548480

    Full Text Available Multiple sclerosis (MS, the most frequent demyelinating disease in adults, is thought to be an autoimmune disease. Symptoms and signs observed in MS reflect lesions present mainly in the white matter of the central nervous system (CNS. The diagnosis remains difficult, at least concerning presenting symptoms, because of their low specificity. Diagnosis criteria are usually based on dissemination of signs in time and space, evoked potentials, findings of magnetic resonance imaging, results of cerebrospinal fluid examination, and the exclusion of other diagnosis possibly explaining the clinical signs. However, no clinical and paraclinical investigation can distinguish with certainity MS from other conditions such as autoimmune or inflammatory diseases predominantly affecting the central nervous system. These other disorders include systemic lupus erythematosus, antiphospholipid syndrome, Behcet disease, Sjogren syndrome, sarcoidosis and vasculitides. We present four clinical cases showing the difficulty in reaching a proper diagnosis...

    To evaluate clinical and dosimetric factors retrospectively affecting the risk of symptomatic cardiac disease (SCD) in esophageal cancer patients treated with radiotherapy. A total of 343 patients with newly diagnosed esophageal cancer were managed with concurrent chemoradiotherapy or radiotherapy alone. Of these, 58 patients were followed at our hospital for at least 4 years. Median clinical follow-up was 79 months. Cardiac toxicity was determined by Common Terminology Criteria for Adverse Events (CTCAE) v. 4.0. The maximum and mean doses to the heart and percentage of the volume were calculated from the dose-volume histograms. SCD manifested in 11 patients. The heart diseases included three pericardial effusions, one pericardial effusion with valvular disease and paroxysmal atrial tachycardia, three atrial fibrillations, one sinus tachycardia, one coronary artery disease, one chest pain with strongly suspected coronary artery disease, and one congestive heart failure. The actual incidence of SCD was 13.8 % at 5 years. Univariate and multivariate analyses of continuous variables revealed that the risk of developing an SCD depended on the volume of the heart receiving a dose greater than 45 Gy (V45), 50 Gy (V50), and 55 Gy (V55). No other clinical factors were found to influence the risk of SCD. For V45, V50, and V55, the lowest significant cutoff values were 15, 10, and 5 %, respectively. High-dose and large-volume irradiation of the heart increased the risk of SCD in long-term survivors. Using modern radiotherapy techniques, it is important to minimize the heart dose-volume parameters without reducing the tumor dose. (orig.)

    Pedicle screw and rod instrumentation has become the preferred technique for performing stabilization and fusion in the surgical treatment of lumbar spine degenerative disease. Rigid fixation leads to high fusion rates but may also contribute to stress shielding and adjacent segment degeneration. Thus, the use of semirigid rods made of polyetheretherketone (PEEK) has been proposed. Although the PEEK rods biomechanical properties, such as anterior load sharing properties, have been shown, there are few clinical studies evaluating their application in the lumbar spine surgical treatment. This study examined a retrospective cohort of patients who underwent posterior lumbar fusion for degenerative disease using PEEK rods, in order to evaluate the clinical and radiological outcomes and the incidence of complications.

    Alzheimer disease (AD) is a growing global health and economic issue as elderly populations increase dramatically across the world. Despite the many clinical trials conducted, currently no approved disease-modifying treatment exists. In this commentary, the present status of AD drug development and the grounds for collaborations between government, academia, and industry to accelerate the development of disease-modifying AD therapies are discussed. Official government documents, literature, and news releases were surveyed by MEDLINE and website research. Currently approved anti-AD drugs provide only short-lived symptomatic improvements, which have no effect on the underlying pathogenic mechanisms or progression of the disease. The failure to approve a disease-modifying drug for AD may be because the progression of AD in the patient populations enrolled in clinical studies was too advanced for drugs to demonstrate cognitive and functional improvements. The US Food and Drug Administration and the European Medicines Agency recently published draft guidance for industry which discusses approaches for conducting clinical studies with patients in early AD stages. For successful clinical trials in early-stage AD, however, it will be necessary to identify biomarkers highly correlated with the clinical onset and the longitudinal progress of AD. In addition, because of the high cost and length of clinical AD studies, support in the form of global initiatives and collaborations between government, industry, and academia is needed. In response to this situation, national guidance and international collaborations have been established. Global initiatives are focusing on 2025 as a goal to provide new treatment options, and early signs of success in biomarker and drug development are already emerging.

    2012-05-01

    Full Text Available Abstract Introduction Medulloepithelioma is a rare congenital tumor of the primitive medullary neuroepithelium. A significant proportion of patients with medulloepithelioma arising from the optic nerve die from intracranial spread or cerebral metastasis. Because it has no known distinct clinical features and because of its low frequency, this tumor presents within the first two to six years of life and is usually misdiagnosed clinically as a different type of optic nerve tumor. Here, we describe a new and atypical case of medulloepithelioma of the optic nerve in a 12-year-old boy. To the best of our knowledge, he is the oldest reported patient to present with this disease and, now as an adult, has the longest documented period of disease-free survival. Case presentation A 12-year-old Caucasian boy with headache and unilateral amaurosis was referred for a presumed optic nerve glioma to our hospital. A computed tomography scan showed optic nerve enlargement, and fundoscopy showed a whitish mass at the optic disc. Our patient had been followed at his local hospital for four years for an 'optic disc cyst' with no change or progression. He experienced mild progressive visual impairment during that period. He was admitted for resection, and a histopathological analysis revealed a medulloepithelioma of the optic nerve. Supplemental orbital radiotherapy was performed. He remained disease-free for 25 years. Conclusions Medulloepithelioma of the optic nerve can clinically mimic more common pediatric tumors, such as optic glioma, meningioma, or retinoblastoma. Thus, medulloepithelioma should be included in the differential diagnoses of pediatric optic nerve lesions. Fundoscopy in these patients may provide relevant information for diagnosis. Anterior optic nerve medulloepitheliomas may behave differently from and have a better prognosis than medulloepitheliomas that have a more posterior location. Our case report illustrates that long-term survival can be

    Influenza-Like Illness is a leading cause of hospitalization in children. Disease burden due to influenza and other respiratory viral infections is reported on a population level, but clinical scores measuring individual changes in disease severity are urgently needed. Areas covered: We present a composite clinical score allowing individual patient data analyses of disease severity based on systematic literature review and WHO-criteria for uncomplicated and complicated disease. The 22-item ViVI Disease Severity Score showed a normal distribution in a pediatric cohort of 6073 children aged 0-18 years (mean age 3.13; S.D. 3.89; range: 0 to 18.79). Expert commentary: The ViVI Score was correlated with risk of antibiotic use as well as need for hospitalization and intensive care. The ViVI Score was used to track children with influenza, respiratory syncytial virus, human metapneumovirus, human rhinovirus, and adenovirus infections and is fully compliant with regulatory data standards. The ViVI Disease Severity Score mobile application allows physicians to measure disease severity at the point-of care thereby taking clinical trials to the next level.

  12. Long-term Outcomes of Elective Surgery for Diverticular Disease: A Call for Standardization.

    2016-10-01

    To date, the appropriate management of diverticular disease is still controversial. The American Society of Colon and Rectal Surgeons declared that the decision between conservative or surgical approach should be taken by a case-by-case evaluation. There is still lack of evidence in literature about long-term outcomes after elective sigmoid resection for diverticular disease. Considering the potentially key role of the surgical technique in long-term outcomes, there is the need for surgeons to define strict rules to standardize the surgical technique. Currently there are 5 areas of debate in elective surgery for diverticular disease: laparoscopic versus open approach, the site of the proximal and distal colonic division, the vascular approach and the mobilization of the splenic flexure. The purpose of this paper is to review existing knowledge about technical aspects, which represent how the surgeon is able to affect the long-term results.

    Full Text Available Aim: Moyamoya disease (MMD is a rare, progressive and oclusive cerebrovascular disorder, predominantly affecting the terminal segment of the internal carotid arteries (ICA and its main branches. The purpose of this study is to evaluate the clinical course and severity of MMD in pediatric patients. Material and Method: We examined 5 consecutive pediatric patients with MMD, focusing on clinical and radiological features, the therapy and outcome over the 58-month follow-up period. Results: The study population consisted of 3 boys and 2 girls. The mean age at diagnosis of patients was 7.2 ± 3.4 years (age range: 3-10 years. The mean duration of follow-up was 30.4 ± 17.4 months (follow-up interval: 12-58 months. Neurological findings at presentation included: motor deficit in 4 patients (80.0%, epileptic seizures in 2 patients (40.0%, movement disorders in 3 patients (60.0%, and headache in 1 patients (20.0%. There was areas of infarction on brain MRI in all patients. Angiographic findings included: internal carotid artery stenosis in all patients, anterior cerebral artery stenosis in 3 patients, middle cerebral artery stenosis in 3 patients, posterior cerebral artery stenosis in 2 patients, and vertebral artery stenosis in 1 patient. Enoxaparine therapy was started to all patients. Subdural hematoma developed in 1 patient during follow-up. Cerebral infarctions recurred despite medical treatment in 4 patients. Discussion: Although this disease is rare, it is an important cause of pediatric stroke. MMD shows different clinical course and disease severity in childhood. Early diagnosis and appropriate treatment are crucial.

    Treatment alternatives for persistent and recurrent Cushing disease (CD) include pituitary surgical re-intervention, radiation therapy (RT), pharmacotherapy, and bilateral adrenalectomy (BA). The decision of which of these alternatives is better suited for the individual patient rests on clinical judgment and the availability of resources. This retrospective cohort study was performed at a referral center to evaluate the long-term efficacy of different secondary interventions for persistent and recurrent CD. We evaluated the hospital charts of 84 patients (77 female, median age 34 years, median follow up 6.3 years) with CD diagnosed, treated, and followed at our multidisciplinary clinic according to a pre-established protocol. Of the 81 patients who were initially treated with transsphenoidal surgery (TSS), 61.7% had a long-lasting remission, 16% had persistent disease, and 22% achieved remission but relapsed during follow-up. The most frequently used secondary treatment was pituitary re-intervention, followed by ketoconazole, RT, and BA. Early remissions were observed in 66.6% of the re-operated and in 58.3% of the radiated patients; long-lasting remission was achieved in 33.3% and 41.6% of these patients, respectively. Nelson syndrome developed in 41.6% of the patients who underwent BA. Upon last follow-up, 88% of all the patients are in remission, and 9.5% are biochemically controlled with ketoconazole. The efficacy of treatment alternatives for recurrent or persistent CD varies considerably among patients and multiple interventions are often required to achieve long-lasting remission. ACTH = adrenocorticotrophic hormone; BA = bilateral adrenalectomy; CBG = cabergoline; CD = Cushing disease; CV = coefficient of variation; DXM = dexamethasone; IQR = interquartile range; RT = radiation therapy; SRS = stereotactic radiosurgery; TSS = transsphenoidal surgery; UFC = urinary free cortisol; ULN = upper limit of normal.

    Full Text Available Introduction: Kikuchi-Fujimoto disease is an uncommon disorder with worldwide distribution, characterized by fever and benign enlargement of the lymph nodes, primarily affecting young adults. Awareness about this disorder may help prevent misdiagnosis and inappropriate investigations and treatment. The objective of the study was to evaluate the clinical and laboratory characteristics of histopathologically confirmed cases of Kikuchi′s disease from a tertiary care center in southern India. Materials and Methods: Retrospective analysis of all adult patients with histopathologically confirmed Kikuchi′s disease from January 2007 to December 2011 in a 2700-bed teaching hospital in South India was done. The clinical and laboratory characteristics and outcome were analyzed. Results: There were 22 histopathologically confirmed cases of Kikuchi′s disease over the 5-year period of this study. The mean age of the subjects′ was 29.7 years (SD 8.11 and majority were women (Male: female- 1:3.4. Apart from enlarged cervical lymph nodes, prolonged fever was the most common presenting complaint (77.3%. The major laboratory features included anemia (54.5%, increased erythrocyte sedimentation rate (31.8%, elevated alanine aminotransferase (27.2% and elevated lactate dehydrogenase (LDH (31.8%. Conclusion: Even though rare, Kikuchi′s disease should be considered in the differential diagnosis of young individuals, especially women, presenting with lymphadenopathy and prolonged fever. Establishing the diagnosis histopathologically is essential to avoid inappropriate investigations and therapy.

    Imprecision in terms used in the field of clinical nutrition may lead to misinterpretations among professionals. For this reason, the Spanish Society of Endocrinology and Nutrition (SEEN) promoted this document on the terms and definitions used in clinical artificial nutrition (enteral and parenteral), establishing an agreement between Spanish experts of this specialty. Forty-seven specialists in endocrinology and nutrition, members of the Nutrition Area of the SEEN, participated between April and September 2016. After a systematic literature review, 52 concepts were proposed. The coordinators included two additional concepts, and 57were finally selected by the working group: 13 of a general nature, 30 referring to enteral nutrition and 14 to parenteral nutrition. The degree of agreement was subsequently determined using a two-round Delphi process. It was finally ratified by consistency and concordance analysis. Fifty-four of the 57 terms had a very consistent agreement and were concordant. Only three showed no concordance, of whom two were very consistent and one inconsistent. In conclusion, there was consensus in the definition of 54 basic terms in the practice of clinical nutrition. Copyright © 2017 SEEN y SED. Publicado por Elsevier España, S.L.U. All rights reserved.

    By November 2013, a total of 125 clinical practice guidelines (CPGs) have been developed in Korea. However, despite the high burden of diseases and the clinical importance of CPGs, most chronic diseases do not have available CPGs. Merely 83 CPGs are related to chronic diseases, and only 40 guidelines had been developed in the last 5 yr. Considering the rate of the production of new evidence in medicine and the worsening burden from chronic diseases, the need for developing CPGs for more chronic diseases is becoming increasingly pressing. Since 2011, the Korean Academy of Medical Sciences and the Korea Centers for Disease Control and Prevention have been jointly developing CPGs for chronic diseases. However, priorities have to be set and resources need to be allocated within the constraint of a limited funding. This study identifies the chronic diseases that should be prioritized for the development of CPGs in Korea. Through an objective assessment by using the analytic hierarchy process and a subjective assessment with a survey of expert opinion, high priorities were placed on ischemic heart disease, cerebrovascular diseases, Alzheimer's disease and other dementias, osteoarthritis, neck pain, chronic kidney disease, and cirrhosis of the liver.

  2. A generalizable pre-clinical research approach for orphan disease therapy

    Full Text Available Abstract With the advent of next-generation DNA sequencing, the pace of inherited orphan disease gene identification has increased dramatically, a situation that will continue for at least the next several years. At present, the numbers of such identified disease genes significantly outstrips the number of laboratories available to investigate a given disorder, an asymmetry that will only increase over time. The hope for any genetic disorder is, where possible and in addition to accurate diagnostic test formulation, the development of therapeutic approaches. To this end, we propose here the development of a strategic toolbox and preclinical research pathway for inherited orphan disease. Taking much of what has been learned from rare genetic disease research over the past two decades, we propose generalizable methods utilizing transcriptomic, system-wide chemical biology datasets combined with chemical informatics and, where possible, repurposing of FDA approved drugs for pre-clinical orphan disease therapies. It is hoped that this approach may be of utility for the broader orphan disease research community and provide funding organizations and patient advocacy groups with suggestions for the optimal path forward. In addition to enabling academic pre-clinical research, strategies such as this may also aid in seeding startup companies, as well as further engaging the pharmaceutical industry in the treatment of rare genetic disease.

    Characteristic images of 99m Tc-MDP bone scintigraphy in patients with metabolic bone diseases (MBD) were analyzed and compared, in an attempt to improve the capability of differential diagnosis in this aspect. A total of 142 cases, clinically confirmed as (MBD), were categorized into six groups: hyperparathyroidism (117), renal osteodystrophy (4), Paget's disease (16), hypophosphatemic osteomalacia (2), Albers-Schonberg disease (2), and Brittle bone disease (1). They were diagnosed clinically or pathologically, and scanned with 99m Tc-MDP bone scintegraphy, from which the 142 MBD cases were classified into 4 types. The cases of Type I had increased amount of 99m Tc-MDP uptake in whole body bones, including hyperparathyroidism, Albers-Schonberg disease, brittle bone disease and renal osteodystrophy. The cases of Type II had high uptake of 99m Tc-MDP in local region of bones, including paget's disease, hypophosphatemic osteomalacia and hyperparathyroidism. A Type I case with pathological fracture or secondary osteopathy was classified as Type III. Type IV cases were in early stage of hyperparathyroidism, with normal bone scan image. Analysis of the characteristics of 99m Tc-MDP bone scintigraphic findings (locations, morphology and intensities) in patients with MBD may be helpful in the differential diagnosis of MBD, in association with the patient's history and X-ray data altogether.

    2018-05-08

    Cosmetic products are commonly marketed using dermatologic terms such as 'hypoallergenic', 'non-comedogenic', 'fragrance-free', etc. The clinical relevance of these claims can be confusing to both patients and clinicians. A systematic review was performed via a PubMed search of published articles from January 1985 to October 2017 to further describe and elucidate the clinical utility of a predefined list of common dermatologic terms used by pharmaceutical companies to market over-the-counter products. The terms 'fragrance-free', 'hypoallergenic', 'non-comedogenic', and 'oil-free' on cosmetic product labels are not regulated by any governing body and provide varied clinical utility. Products labeled as having 'natural ingredients' are not necessarily safer or less irritating to patients with atopy or a history of allergic contact dermatitis. Despite the increasing popularity of 'paraben-free' cosmetics, parabens are safe for patients in the quantities used in cosmetic products and can be safely used in patients who do not exhibit contact dermatitis to this preservative. A working knowledge of common cosmetic ingredients may help dermatologists to counsel patients on which products to avoid for their specific dermatologic conditions.

In so far only a part of body is affected by dystonic movement, it is the question of focal dystonia, which is called writer's cramp if the arm is involved. OBJECTIVE The objective of the study was to present the specific clinical features of patients with task-specific dystonia, who were diagnosed, treated and followed up at the Institute of Neurology, Clinical Center of Serbia, Belgrade. MATERIAL AND METHODS In the period 1995-2003, 30 patients with task-specific dystonia were treated at the Institute of Neurology, CCS, who met the adopted criteria for diagnosis. The severity of the diseases was tested by estimating the ability of patient to write the test sentence per time unit, as well as by means of scale for measuring different disabilities, ranging from 0-16 (Marsden-Fahn. Depression, anxiety and obsessiveness were tested by Beck's scale, Hamilton's depression and anxiety scale and Mousdly's obsessiveness scale. Thorough questionnaire focused on clinical details was also used. Besides descriptive statistics, data processing included analysis of variance and Kruskal-Wallis's test. RESULTS Thirty patients with diagnosis of task-specific dystonia were analyzed. At the onset of the disease, mean-age was 34.1 years (SD=11.4; 13-58, while the duration of disease at the moment of the examination was 10.3 years (SD=10.6; 1-39.

    Surgical septal myectomy is performed to relieve left ventricular outflow tract narrowing in severe drug-refractory obstructive hypertrophic cardiomyopathy. The objective of this study was to assess the perioperative and long-term clinical outcome of this procedure performed during infancy. Clinical, transthoracic echocardiographic, electrocardiographic, 24-h Holter, cardiopulmonary exercise test and genetic data were extracted by medical record review. A subset of patients underwent additional prospective detailed clinical evaluation including cardiac magnetic resonance imaging with contrast. Surgery was performed in 23 paediatric patients between 1978 and 2015 at the German Heart Centre Munich. Twelve patients had undergone surgery during infancy (≤ 1 year) (Group A), 11 between 1 and 18 years of age (Group B). The underlying genetic diagnosis was Noonan syndrome spectrum and non-syndromic hypertrophic cardiomyopathy. As compared to Group B, patients in Group A showed more concomitant cardiac procedures and received more homologous transfusions. One perioperative death occurred in Group A, and none in Group B. Two patients in Group A but no patient in Group B required redo septal myectomy. The long-term clinical outcome was similar between the 2 groups. One patient in Group B required cardioverter-defibrillator/pacemaker implantation for higher degree atrioventricular block and none in Group A. There was no evidence of differences in myocardial fibrosis between groups on long-term follow-up magnetic resonance imaging. Surgical septal myectomy can be performed safely during infancy with favourable perioperative and long-term clinical outcome but with a trend towards a higher reoperation rate later in life. © The Author 2017.

    Oxidative stress is a metabolic condition arising from imbalance between the production of potentially reactive oxygen species and the scavenging activities. Mitochondria are the main providers but also the main scavengers of cell oxidative stress. The role of mitochondrial dysfunction and oxidative stress in the pathogenesis of neurodegenerative diseases is well documented. Therefore, therapeutic approaches targeting mitochondrial dysfunction and oxidative damage hold great promise in neurodegenerative diseases. Despite this evidence, human experience with antioxidant neuroprotectants has generally been negative with regards to the clinical progress of disease, with unclear results in biochemical assays. Here we review the antioxidant approaches performed so far in neurodegenerative diseases and the future challenges in modern medicine.

    2014-09-01

    With the progress of technologies of recent years, methods have become available that use wearable sensors and ambulatory systems to measure aspects of--particular axial--motor function. As Parkinson's disease (PD) can be considered a model disorder for motor impairment, a significant number of studies have already been performed with these patients using such techniques. In general, motion sensors such as accelerometers and gyroscopes are used, in combination with lightweight electronics that do not interfere with normal human motion. A fundamental advantage in comparison with usual clinical assessment is that these sensors allow a more quantitative, objective, and reliable evaluation of symptoms; they have also significant advantages compared to in-lab technologies (e.g., optoelectronic motion capture) as they allow long-term monitoring under real-life conditions. In addition, based on recent findings particularly from studies using functional imaging, we learned that non-motor symptoms, specifically cognitive aspects, may be at least indirectly assessable. It is hypothesized that ambulatory quantitative assessment strategies will allow users, clinicians, and scientists in the future to gain more quantitative, unobtrusive, and everyday relevant data out of their clinical evaluation and can also be designed as pervasive (everywhere) and intensive (anytime) tools for ambulatory assessment and even rehabilitation of motor and (partly) non-motor symptoms in PD. © 2014 John Wiley & Sons A/S.

Patients who were seen as new cases in a local male infertility clinic between January 2008 and December 2012. Infertility assessment and counselling on treatment options. Disease spectrum and treatment patterns. A total of 387 new patients were assessed in the male infertility clinic. The mean age of the patients and their female partners was 37.2 and 32.1 years, respectively. The median duration of infertility was 3 years. Among the patients, 36.2% had azoospermia, 8.0% had congenital absence of vas deferens, and 48.3% of patients had other abnormalities in semen parameters. The commonest causes of male infertility were unknown (idiopathic), clinically significant varicoceles, congenital absence of vas deferens, mumps after puberty, and erectile or ejaculatory dysfunction. Overall, 66.1% of patients chose assisted reproductive treatment and 12.4% of patients preferred surgical correction of reversible male infertility conditions. Altogether 36.7% of patients required either surgical sperm retrieval or correction of male infertility conditions. The present study provided important local data on the disease spectrum and treatment patterns in a male infertility clinic. The incidences of azoospermia and congenital absence of vas deferens were much higher than those reported in the contemporary literature. A significant proportion of patients required either surgical sperm retrieval or correction of reversible male infertility conditions.

    Structural imaging based on magnetic resonance is an integral part of the clinical assessment of patients with suspected Alzheimer dementia. Prospective data on the natural history of change in structural markers from preclinical to overt stages of Alzheimer disease are radically changing how the disease is conceptualized, and will influence its future diagnosis and treatment. Atrophy of medial temporal structures is now considered to be a valid diagnostic marker at the mild cognitive impairment stage. Structural imaging is also included in diagnostic criteria for the most prevalent non-Alzheimer dementias, reflecting its value in differential diagnosis. In addition, rates of whole-brain and hippocampal atrophy are sensitive markers of neurodegeneration, and are increasingly used as outcome measures in trials of potentially disease-modifying therapies. Large multicenter studies are currently investigating the value of other imaging and nonimaging markers as adjuncts to clinical assessment in diagnosis and monitoring of progression. The utility of structural imaging and other markers will be increased by standardization of acquisition and analysis methods, and by development of robust algorithms for automated assessment.

    Past clinical trials of putative neuroprotective therapies have targeted Parkinson disease (PD) as a single pathogenic disease entity. From an Oslerian clinico-pathologic perspective, the wide complexity of PD converges into Lewy bodies and justifies a reductionist approach to PD: a single-mechanism therapy can affect most of those sharing the classic pathologic hallmark. From a systems-biology perspective, PD is a group of disorders that, while related by sharing the feature of nigral dopamine-neuron degeneration, exhibit unique genetic, biological and molecular abnormalities, which probably respond differentially to a given therapeutic approach, particularly for strategies aimed at neuroprotection. Under this model, only biomarker-defined, homogenous subtypes of PD are likely to respond optimally to therapies proven to affect the biological processes within each subtype. Therefore, we suggest that precision medicine applied to PD requires a reevaluation of the biomarker-discovery effort. This effort is currently centered on correlating biological measures to clinical features of PD and on identifying factors that predict whether various prodromal states will convert into the classical movement disorder. We suggest, instead, that subtyping of PD requires the reverse view, where abnormal biological signals (i.e., biomarkers) rather than clinical definitions are used to define disease phenotypes. Successful development of disease-modifying strategies will depend on how relevant the specific biological processes addressed by an intervention are to the pathogenetic mechanisms in the subgroup of targeted patients. This precision-medicine approach will likely yield smaller but well-defined subsets of PD amenable to successful neuroprotection. PMID:28233927

    Both stressors and stress vulnerability factors together with immune and hypothalamus-pituitary-adrenal (HPA) axis activity components have been considered to contribute to disease fluctuations of chronic inflammatory diseases, such as rheumatoid arthritis (RA). The aim of the present study was to investigate whether daily stressors and worrying as stress vulnerability factor as well as immune and HPA axis activity markers predict short-term disease activity and symptom fluctuations in patients with RA. In a prospective design, daily stressors, worrying, HPA axis (cortisol) and immune system (interleukin (IL)-1β, IL-6, IL-8, interferon (IFN)-γ, tumour necrosis factor α) markers, clinical and self-reported disease activity (disease activity score in 28 joints, RA disease activity index), and physical symptoms of pain and fatigue were monitored monthly during 6 months in 80 RA patients. Multilevel modelling indicated that daily stressors predicted increased fatigue in the next month and that worrying predicted increased self-reported disease activity, swollen joint count and pain in the next month. In addition, specific cytokines of IL-1β and IFN-γ predicted increased fatigue 1 month later. Overall, relationships remained relatively unchanged after controlling for medication use, disease duration and demographic variables. No evidence was found for immune and HPA axis activity markers as mediators of the stress-disease relationship. Daily stressors and the stress-vulnerability factor worrying predict indicators of the short-term course of RA disease activity and fatigue and pain, while specific cytokines predict short-term fluctuations of fatigue. These stress-related variables and immune markers seem to affect different aspects of disease activity or symptom fluctuations independently in RA. Published by the BMJ Publishing Group Limited.

    Chronic beryllium disease (CBD) is a granulomatous disorder that affects the lung after exposure to beryllium. The present study reports short- and long-term evolution of granulomatous and fibrotic components in eight patients with severe CBD receiving corticosteroid therapy. Eight patients with confirmed CBD were studied at baseline, after initial corticosteroid treatment (4-12 months), at relapse and at the final visit. Beryllium exposure, Glu(69) (HLA-DPB1 genes coding for glutamate at position beta69) polymorphism, symptoms, pulmonary function tests (PFT), serum angiotensin-converting enzyme (SACE) and high-resolution computed tomography (HRCT) quantification of pulmonary lesions were analysed. The CBD patients were observed for a median (range) of 69 (20-180) months. After stopping beryllium exposure, corticosteroids improved symptoms and PFT (vital capacity +26%, diffusing capacity of the lung for carbon monoxide +15%), and decreased SACE level and active lesion HRCT score. In total, 18 clinical relapses occurred after the treatment was tapered and these were associated with SACE and active lesion HRCT score impairment. At the final visit, corticosteroids had completely stabilised all parameters including both HRCT scores of active lesions and fibrotic lesions in six out of eight patients. Corticosteroids were beneficial in chronic beryllium disease. They were effective in suppressing granulomatosis lesions in all cases and in stopping the evolution to pulmonary fibrosis in six out of eight patients.

    Disease registries, containing systematic records of cases, have for nearly 100 years been valuable in exploring and understanding various aspects of cardiology. This is particularly true for myocardial infarction, where such registries have provided both epidemiological and clinical information that was not readily available from randomised controlled trials in highly-selected populations. Registries, whether mandated or voluntary, prospective or retrospective in their analysis, have at their core a common study population and common data definitions. In this review we highlight how registries have diversified to offer information on epidemiology, risk modelling, quality assurance/improvement and original research-through data mining, transnational comparisons and the facilitation of enrolment in, and follow-up during registry-based randomised clinical trials.

    Network-sensitive neuroimaging methods have been used to characterize large-scale brain network degeneration in Alzheimer's disease and its prodrome. However, few studies have investigated the combined effect of Alzheimer's disease and cerebrovascular disease on brain network degeneration. Our study sought to examine the intrinsic functional connectivity and structural covariance network changes in 235 prodromal and clinical Alzheimer's disease patients with and without cerebrovascular disease. We focused particularly on two higher-order cognitive networks-the default mode network and the executive control network. We found divergent functional connectivity and structural covariance patterns in Alzheimer's disease patients with and without cerebrovascular disease. Alzheimer's disease patients without cerebrovascular disease, but not Alzheimer's disease patients with cerebrovascular disease, showed reductions in posterior default mode network functional connectivity. By comparison, while both groups exhibited parietal reductions in executive control network functional connectivity, only Alzheimer's disease patients with cerebrovascular disease showed increases in frontal executive control network connectivity. Importantly, these distinct executive control network changes were recapitulated in prodromal Alzheimer's disease patients with and without cerebrovascular disease. Across Alzheimer's disease patients with and without cerebrovascular disease, higher default mode network functional connectivity z-scores correlated with greater hippocampal volumes while higher executive control network functional connectivity z-scores correlated with greater white matter changes. In parallel, only Alzheimer's disease patients without cerebrovascular disease showed increased default mode network structural covariance, while only Alzheimer's disease patients with cerebrovascular disease showed increased executive control network structural covariance compared to controls.

    Full Text Available Parkinson’s disease (PD is a common, disabling, neurodegenerative disorder. In addition to classical motor symptoms, nonmotor features are now widely accepted as part of the clinical picture, and cognitive decline is a very important aspect of the disease, as it brings an additional significant burden for the patient and caregivers. The diagnosis of cognitive decline in PD, namely mild cognitive impairment and dementia, can be extremely challenging, remaining largely based on clinical and cognitive assessments. Diagnostic criteria and methods for PD dementia and mild cognitive impairment have been recently issued by expert work groups. This manuscript has synthesized relevant data in order to obtain a pragmatic and updated review regarding cognitive decline in PD, from milder stages to dementia. This text will summarize clinical features, diagnostic methodology, and therapeutic issues of clinical decline in Parkinson’s disease. Relevant clinical genetic issues, including recent advances, will also be approached.

    Full Text Available There is a wide differential diagnosis for the child with unexplained fractures including non-accidental injury, osteogenesis imperfecta and vitamin D deficiency rickets. Over the last 20 years we and others have described a self-limiting syndrome characterised by fractures in the first year of life. This has been given the provisional name temporary brittle bone disease. This work had proved controversial mostly because the fractures, including rib fractures and metaphyseal fractures, were those previously regarded as typical or even diagnostic of non-accidental injury. Some have asserted that the condition does not exist. Over the years 1985 to 2000 we investigated 87 such cases with fractures with a view to determining the future care of the children. In 85 of these the judiciary was involved. We examined the clinical and radiological findings in the 33 cases in which there was a judicial finding of abuse, the 24 cases in which the parents were exonerated and the 28 cases in which no formal judicial finding was made. The three groups of patients were similar in terms of demographics, age at fracturing and details of the fractures. The clinical similarities between the three groups of patients contrasts with the very different results of the judicial process.

    Although the systematic measurement of disease activity facilitates clinical decision making in rheumatoid arthritis (RA), no recommendations currently exist on which measures should be applied in clinical practice in the US. The American College of Rheumatology (ACR) convened a Working Group (WG) to comprehensively evaluate the validity, feasibility, and acceptability of available RA disease activity measures and derive recommendations for their use in clinical practice. The Rheumatoid Arthritis Clinical Disease Activity Measures Working Group conducted a systematic review of the literature to identify RA disease activity measures. Using exclusion criteria, input from an Expert Advisory Panel (EAP), and psychometric analysis, a list of potential measures was created. A survey was administered to rheumatologists soliciting input. The WG used these survey results in conjunction with the psychometric analyses to derive final recommendations. Systematic review of the literature resulted in identification of 63 RA disease activity measures. Application of exclusion criteria and ratings by the EAP narrowed the list to 14 measures for further evaluation. Practicing rheumatologists rated 9 of these 14 measures as most useful and feasible. From these 9 measures, the WG selected 6 with the best psychometric properties for inclusion in the final set of ACR-recommended RA disease activity measures. We recommend the Clinical Disease Activity Index, Disease Activity Score with 28-joint counts (erythrocyte sedimentation rate or C-reactive protein), Patient Activity Scale (PAS), PAS-II, Routine Assessment of Patient Index Data with 3 measures, and Simplified Disease Activity Index because they are accurate reflections of disease activity; are sensitive to change; discriminate well between low, moderate, and high disease activity states; have remission criteria; and are feasible to perform in clinical settings.

    Progressive lung disease in cystic fibrosis (CF) is the life-limiting factor of this autosomal recessive genetic disorder. Increasing implementation of CF newborn screening allows for a diagnosis even in pre-symptomatic stages. Improvements in therapy have led to a significant improvement in survival, the majority now being of adult age. Imaging provides detailed information on the regional distribution of CF lung disease, hence longitudinal imaging is recommended for disease monitoring in the clinical routine. Chest X-ray (CXR), computed tomography (CT) and magnetic resonance imaging (MRI) are now available as routine modalities, each with individual strengths and drawbacks, which need to be considered when choosing the optimal modality adapted to the clinical situation of the patient. CT stands out with the highest morphological detail and has often been a substitute for CXR for regular severity monitoring at specialized centers. Multidetector CT data can be post-processed with dedicated software for a detailed measurement of airway dimensions and bronchiectasis and potentially a more objective and precise grading of disease severity. However, changing to CT was inseparably accompanied by an increase in radiation exposure of CF patients, a young population with high sensitivity to ionizing radiation and lifetime accumulation of dose. MRI as a cross-sectional imaging modality free of ionizing radiation can depict morphological hallmarks of CF lung disease at lower spatial resolution but excels with comprehensive functional lung imaging, with time-resolved perfusion imaging currently being most valuable.

    To study the socio-demographic features, the prescribed remedies and the outcome of atopic diseases in children treated with homeopathy at the Homeopathic Clinic of Lucca (Italy), and the long-term outcome of children suffering from atopic dermatitis (AD) after an approximate 8-year period (range 5-10 years). Our data derive from an observational longitudinal study carried out on 213 children (38.6%) with atopic diseases out of 551 children consecutively examined from September 1998 to December 2008. We used the Glasgow Homeopathic Hospital Outcome Score to evaluate the results that were classified on the basis of a Likert scale. Eighty-three (39%) children were affected by asthma, 51 (24%) by allergic rhinoconjunctivitis, 76 (36%) by AD and 3 (1%) by food intolerance. Follow-up patients were 104 (48.8%), and 65 (62.5%) of them reported a major improvement or resolution. The parents of paediatric patients suffering from AD, who had started homeopathic treatment at homeopathy in atopic children. Furthermore, according to the data from the literature paediatric patients treated with homeopathy seem to show a reduced tendency to maintain AD and develop asthma (and allergic rhinitis) in adult age.

    Full Text Available Lívia Figueiredo, Viviane F Zétola, Marcos C Lange Neurology Division, Hospital de Clínicas, Universidade Federal do Paraná, Curitiba, Brazil Abstract: Carotid and transcranial (CTU ultrasound is a useful tool in a number of clinical settings, particularly in cerebrovascular diseases. CTU is the only method that provides real-time determination of velocity and the spectral waveform of blood flow in the extracranial and basal intracranial arteries, and is effective in the detection of stenosis and occlusion. When transcranial ultrasound is considered, CTU is the only method that allows visualization of microembolic signals in the intracranial arteries. CTU makes a rapid differential diagnosis possible, improving therapeutic decision-making in acute stroke and determining the risk of recurrence and prognosis based on its findings. It is also the standard of care in children with sickle cell disease, when selecting patients for chronic blood transfusion, and for reducing the risk of ischemic stroke in these patients. CTU has some advantages, ie, relative simplicity in terms of interpretation and performance, and affordability, noninvasiveness, and portability. The main concern with ultrasound is that it is an operator-dependent tool and requires a high level of expertise and knowledge of three-dimensional cerebrovascular anatomy for correct interpretation of sonograms. The most significant limitation of intracranial evaluation by transcranial ultrasound is the absence of a suitable bone window in approximately 10% of patients. This paper gives an overview of the current utility and importance of CTU in the prevention and evaluation of ischemic cerebrovascular disease.

HIV-infected patients generally benefit from being treated with antiretroviral drugs, but some antiretroviral agents have side effects, such as dyslipidemia and hyperglycemia. There is general consensus that antiretroviral drugs induce a long-term risk of CHD, although the levels of that risk are somewhat controversial. The intention of this cross-sectional study was to describe the lipid profile and the long-term risk of CHD among HIV-positive outpatients at an HIV treatment clinic in Harare, Zimbabwe. Two hundred and fifteen patients were investigated (females n=165, mean age 39.8 years; males n=50; mean age 42.0 years. Thirty of the individuals were antiretroviral-naïve and 185 had been on antiretroviral therapy (ART for a mean 3.9±3.4 years. All participants had average lipid and glucose values within normal ranges, but there was a small difference between the ART and ART- for total cholesterol (TC and high-density lipoprotein (HDL.Those on a combination of D4T or ZDV/NVP/3TC and PI-based ART were on average oldest and had the highest TC levels. Framingham risk showed 1.4% prevalence of high CHD risk within the next ten years. After univariate analysis age, sex, TC/HDL ratio, HDL, economic earnings and systolic BP were associated with medium to high risk of CHD. After multivariate regression analysis and adjusting for age or sex only age, sex and economic earnings

    The main aim of the study is to study the clinical profile of disorders of the liver and hepatobiliary system in paediatric patients and to correlate the histopathology findings of liver biopsy in chronic liver disease. Another aim being to assess the prognosis and to know the outcome and the effects of treatment in chronic liver diseases in paediatric age group. It was a prospective study, included the clinical profile of Chronic Liver Diseases (CLD) in children and the histopathological correlation. A total of 55 children were thoroughly investigated by doing relevant investigations and liver biopsy. A male predominance (60%) was noted with maximum incidence in the age group of 6-12 years. The incidence of CLD was 1.1% of total admissions. The most common presenting complaint was jaundice and abdominal distension. Hepatic encephalopathy was noted in 29% patients. Hepatomegaly was seen in 63% patients and spleenomegaly was seen in 60% patients. The incidence of cirrhosis on liver biopsy was 42% (23cases) in CLD patients. The most common diagnosis on histopathology was Wilson's disease (22%), followed by hepatitis and autoimmune hepatitis. The predominant spectrum of CLD was metabolic liver disease and also the predominant cause of death. As the incidence of CLD is quite low, a very high index of suspicion is required for its diagnosis. Some uncommon causes of CLD in children were seen in our study like neutral lipid storage disease, α1-Antitrypsin deficiency disease, lupus hepatitis, Alagille syndrome and Budd-Chiari syndrome. A patient of CLD with jaundice and hepatomegaly should be treated aggressively as those are the poor prognostic indicators of the disease. Hepatic encephalopathy and cirrhosis are also associated with poor outcome in patients with CLD. Liver biopsy histopathology by an expert and its correlation with laboratory investigations plays an important role in the diagnosis of CLD. The major cause of deaths in patients with CLD is due to end stage

    Full Text Available Hypertension is a globally prevalent condition, with a heavy clinical and economic burden. It is the predominant risk factor for premature cardiovascular and cerebrovascular disease, and is associated with a variety of clinical disorders including stroke, congestive cardiac failure, ischaemic heart disease, chronic renal failure, and peripheral arterial disease. A significant subset of hypertensive patients have resistant hypertensive disease. In this group of patients, catheter-based renal artery denervation has emerged as a potential therapy, with favourable clinical efficacy and safety in early trials. Additional benefits of this therapy are also being identified and include effects on left ventricular remodeling, cardiac performance, and symptom status in congestive cardiac failure. Utility of renal denervation for the management of resistant hypertension, however, has become controversial since the release of the Symplicity HTN-3 trial, the first large-scale blinded randomised study investigating the efficacy and safety of renal artery denervation. The aim of this paper is to evaluate the history, utility, and clinical efficacy of renal artery denervation technology, including an in-depth appraisal of the current literature and principal trials.

    Impairments in acoustically cued repetitive finger movement often emerge at rates near to and above 2Hz in persons with Parkinson's Disease (PD) in which some patients move faster (hastening) and others move slower (bradykinetic). The clinical features impacting this differential performance of repetitive finger movement remain unknown. The purpose of this study was to compare repetitive finger movement performance between the more and less affected side, and the difference in clinical ratings among performance groups. Forty-one participants diagnosed with idiopathic PD completed an acoustically cued repetitive finger movement task while "on" medication. Eighteen participants moved faster, 10 moved slower, and 13 were able to maintain the appropriate rate at rates above 2Hz. Clinical measures of laterality, disease severity, and the UPDRS were obtained. There were no significant differences between the more and less affected sides regardless of performance group. Comparison of disease severity, tremor, and rigidity among performance groups revealed no significant differences. Comparison of posture and postural instability scores revealed that the participants that demonstrated hastening had worse posture and postural instability scores. Consideration of movement rate during the clinical evaluation of repetitive finger movement may provide additional insight into varying disease features in persons with PD.

    The use of diffusion MRI improved the accuracy of diagnosis in Creutzfeldt-Jakob disease (CJD) and expanded our knowledge of the changes occurring in the brain during the disease. The aim of this study was to test whether in patients with E200K familial CJD (fCJD) the clinical severity correlates with the disease burden as reflected by the extent of cortical involvement in DWI MRI. Consecutive fCJD patients were examined by a neurologist who performed several tests including the CJD neurological scale (CJD-NS), MiniMental status examination (MMSE), Frontal Assessment Battery (FAB), NIH Stroke Scale (NIHSS), and the expanded disability status scale (EDSS). A simultaneously acquired MRI was analyzed by measuring the extent of cortical involvement in the DWI axial sequence. Correlations were tested for using Pearson test. Fifty-two fCJD patients (35 males, mean age 59.4 ± 5.7 years) were recruited to the study. Significant negative correlation was found between the extent of cortical involvement and the cognitive performance of the patients as reflected by their MMSE and FAB scores. In addition, a significant positive correlation was found between the MRI and the clinical disease severity scales CJD-NS and EDSS. The correlation between clinical scales of severity and cognitive dysfunction and the disease burden confirms the reliability of the CJD-NS scale. Further studies are warranted to examine whether MRI may serve not only for diagnosis but also as a biomarker for follow-up of disease progression and the efficacy of potential treatments.

    A review was made to go deep into the understanding of vascular dementias that behave as the second cause of dementia in practice. Binswanger's disease is one of the most important among them. Its detection has progressively increased with the continual improvement of the radiological diagnostic tools that allow to identify the ischemic damage of the hemispherical cerebral white matter and the presence of lacunar infarctions. It is a disease of chronic course and inexorably progressive that is characterized by the association of subcortical cognitive dysfunction, evidence of cerebrovascular disease, Parkinsonian rigidity and vesicle dysfunction with a characteristic imaging picture. The clinical picture and the main imaging characteristics are explained in this paper and the pathogens of the disease is briefly described

    2017-10-01

    Full Text Available Tolerogenic dendritic cell (tDC-based clinical trials for the treatment of autoimmune diseases are now a reality. Clinical trials are currently exploring the effectiveness of tDC to treat autoimmune diseases of type 1 diabetes mellitus, rheumatoid arthritis, multiple sclerosis (MS, and Crohn’s disease. This review will address tDC employed in current clinical trials, focusing on cell characteristics, mechanisms of action, and clinical findings. To date, the publicly reported human trials using tDC indicate that regulatory lymphocytes (largely Foxp3+ T-regulatory cell and, in one trial, B-regulatory cells are, for the most part, increased in frequency in the circulation. Other than this observation, there are significant differences in the major phenotypes of the tDC. These differences may affect the outcome in efficacy of recently launched and impending phase II trials. Recent efforts to establish a catalog listing where tDC converge and diverge in phenotype and functional outcome are an important first step toward understanding core mechanisms of action and critical “musts” for tDC to be therapeutically successful. In our view, the most critical parameter to efficacy is in vivo stability of the tolerogenic activity over phenotype. As such, methods that generate tDC that can induce and stably maintain immune hyporesponsiveness to allo- or disease-specific autoantigens in the presence of powerful pro-inflammatory signals are those that will fare better in primary endpoints in phase II clinical trials (e.g., disease improvement, preservation of autoimmunity-targeted tissue, allograft survival. We propose that pre-treatment phenotypes of tDC in the absence of functional stability are of secondary value especially as such phenotypes can dramatically change following administration, especially under dynamic changes in the inflammatory state of the patient. Furthermore, understanding the outcomes of different methods of cell delivery and sites

    Linari, Silvia; Castaman, Giancarlo

    2015-01-01

    Gaucher disease is a rare multi-systemic metabolic disorder caused by the inherited deficiency of the lysosomal enzyme β-glucocerebrosidase, which leads to the accumulation of its normal substrate, glucocerebroside, in tissue macrophages with damage to haematological, visceral and bone systems. Anaemia, thrombocytopenia, enlargement of liver and/or spleen, skeletal abnormalities (osteopenia, lytic lesions, pathological fractures, chronic bone pain, bone crisis, bone infarcts, osteonecrosis and skeletal deformities) are typical manifestations of the most prevalent form of the disease, the so-called non-neuronopathic type 1. However, severity and coexistence of different symptoms are highly variable. The determination of deficient β-glucocerebrosidase activity in leukocytes or fibroblasts by enzymatic assay is the gold standard for the diagnosis of Gaucher disease. Comprehensive and reproducible evaluation and monitoring of all clinically relevant aspects are fundamental for the effective management of Gaucher disease patients. Enzyme replacement therapy has been shown to be effective in reducing glucocerebroside storage burden and diminishing the deleterious effects caused by its accumulation. Tailored treatment plan for each patient should be directed to symptom relief, general improvement of quality of life, and prevention of irreversible damage.

    Main features of clinics and therapy of acute radiation disease at the recovery period are described. Search for ways of activization of recovery to improve the efficiency of treatments and to accelerate patients rehabilitation is of great interest for clinical medicine. It is outlined that correction of post-irradiation disorders of energy and plastic metabolism by means of influence on cell metabolism must begin as early as possible already at the initial period of disease

    Full Text Available Purpose: To describe the polymorphic expression of Stargardt disease in a large Tunisian family with clinical intra- and interfamilial variation of the condition. Methods: Twelve subjects from two related families with autosomal recessive Stargardt disease were enrolled. A detailed clinical examination including visual acuity and visual field measurement, fundus photography, fluorescein angiography, electroretinography (ERG and color vision testing was performed for all subjects. Results: The youngest child from family A manifested typical Stargardt disease while her two brothers presented with Stargardt disease-fundus flavimaculatus (STGD-FFM and her two sisters demonstrated a peculiar phenotype overlapping Stargardt disease and cone-rod dystrophy; their phenotypic manifestation corresponded well with ERG groups I, II and III, respectively. This uncommon occurrence of an age-related decline in ERG amplitude and worsening of fundus changes is suggestive of a grading pattern in Stargardt disease. Their two cousins in family B, displayed the STGD-FFM phenotype. Despite clinically similar STGD-FFM patterns in both families, age of onset and progression of the phenotype in family B differed from family A. Conclusion: This is the first report on phenotypic variation of Stargardt disease in a large Tunisian family. Regarding phenotype and severity of visual symptoms, family A demonstrated Stargardt disease at various stages of progression. In addition, STGDFFM appeared to be an independent clinical entity in family B. These findings imply that further parameters are required to classify Stargardt′s disease.

    Full Text Available Myotonic dystrophy type 1, also known as Steinert′s disease, is an autosomal dominant disorder with multisystemic clinical features affecting the skeletal and cardiac muscles, the eyes, and the endocrine system. Thiamine (vitamin B1 is a cofactor of fundamental enzymes involved in the energetic cell metabolism; recent studies described its role in oxidative stress, protein processing, peroxisomal function, and gene expression. Thiamine deficiency is critical mainly in the central and peripheral nervous system, as well as in the muscular cells. Our aim was to investigate the potential therapeutical effects of long-term treatment with thiamine in myotonic dystrophy type 1 in an observational open-label pilot study. We described two patients with myotonic dystrophy type 1 treated with intramuscular thiamine 100 mg twice a week for 12 or 11 months. We evaluated the patients using the grading of muscle strength according to Medical Research Council (MRC, the Muscular Impairment Rating Scale (MIRS, and the Modified Barthel index. High-dose thiamine treatment was well tolerated and effective in improving the motor symptomatology, particularly the muscle strength evaluated with the MRC scale, and the patients′ activities of daily living using the Modified Barthel Index. At the end of treatment, the MRC score was 5 in the proximal muscles and 2-4 in the distal muscles (the MRC score before the treatment was 3-4 and 1-3, respectively. The MIRS grade improved by 25% compared to baseline for both patients. In patient #1, the Modified Barthel Index improved by 44%, and in patient #2 by 29%. These findings suggest that clinical outcomes are improved by long-term thiamine treatment.

    Full Text Available Background: Abnormalities of the nail unit are common in patients with connective tissue diseases. Clinical examination of the nail unit, coupled with biopsy of proximal nail fold offers an additional advantage in the diagnosis. Purpose: Our aim was to record clinical changes of the nail unit in connective tissue diseases and to study the histopathological (both H and E and periodic acid Schiff and direct immunofluorescence (DIF findings of nail-fold biopsy. Materials and Methods: Thirty-eight confirmed cases connective tissue diseases attending skin OPD were enrolled in the study. After detailed clinical examination of the nail unit, a crescentric biopsy was taken from the proximal nail fold (PNF. Histopathological and DIF studies were was carried out. Findings: Nail changes could be demonstrated in 65% connective tissue diseases. Specific histopathological (H and E and immunofluorescence findings were also encountered in many patients. Conclusion: Clinical examination of the nail unit offers additional clue in the diagnosis of connective tissue diseases. Though DIF of PNF biopsy is useful in the diagnosis, it is not an ideal site for H and E study, as the yield is very low. Limitations: Lack of adequate comparison group and non-utilization of capillary microscopy for the detection of nail fold capillary abnormalities.

  9. Bronchopulmonary Dysplasia: Chronic Lung Disease of Infancy and Long-Term Pulmonary Outcomes

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Bronchopulmonary dysplasia (BPD is a chronic lung disease most commonly seen in premature infants who required mechanical ventilation and oxygen therapy for acute respiratory distress. While advances in neonatal care have resulted in improved survival rates of premature infants, limited progress has been made in reducing rates of BPD. Lack of progress may in part be attributed to the limited therapeutic options available for prevention and treatment of BPD. Several lung-protective strategies have been shown to reduce risks, including use of non-invasive support, as well as early extubation and volume ventilation when intubation is required. These approaches, along with optimal nutrition and medical therapy, decrease risk of BPD; however, impacts on long-term outcomes are poorly defined. Characterization of late outcomes remain a challenge as rapid advances in medical management result in current adult BPD survivors representing outdated neonatal care. While pulmonary disease improves with growth, long-term follow-up studies raise concerns for persistent pulmonary dysfunction; asthma-like symptoms and exercise intolerance in young adults after BPD. Abnormal ventilatory responses and pulmonary hypertension can further complicate disease. These pulmonary morbidities, combined with environmental and infectious exposures, may result in significant long-term pulmonary sequalae and represent a growing burden on health systems. Additional longitudinal studies are needed to determine outcomes beyond the second decade, and define risk factors and optimal treatment for late sequalae of disease.

    This study attempts a critical evaluation of the clinical evidence behind the use of dietary pomegranate preparations in the prevention and treatment of cardiovascular diseases. A search of PubMed on August 10, 2014 identified 228 references, which yielded extractable data from 24 clinical studies of pomegranate preparations. Hand searching identified two further studies. The quality of the studies and evidence of effectiveness of pomegranate were assessed by an established set of conventional criteria. Overall, the study quality was poor. Even in the best studies, indications of benefit did not reach the conventional levels of statistical significance. The only study with a definitive design had a biochemical rather than a clinical endpoint: it showed the expected difference in blood concentrations of myeloperoxidase after a single dose of either pomegranate or placebo. Only 10 of the 26 studies provided HPLC data on the amounts of co-active ingredients in the preparations that were consumed by the subjects. If pomegranate has a role in the prevention and treatment of cardiovascular diseases, there is a pressing need for dose-finding and long-term confirmatory studies. The ultimate endpoint for definitive studies would be mortality, but reductions in blood pressure or demonstrable decreases in atherosclerotic plaques would be useful surrogates. Sample sizes for various assumptions are provided. Future studies need to prove the clinical benefit. Copyright © 2015 John Wiley & Sons, Ltd.

    Purpose: In children with chiasmal gliomas, radiation therapy can arrest progressive visual and neurologic impairment. We examined the radiographic response and clinical outcomes after irradiation. Methods and Materials: Forty-two children (median age at diagnosis, 6.6 years) with chiasmal gliomas were managed as follows: 11 asymptomatic patients with neurofibromatosis-1 (NF-1) were observed only; 2 patients, less than 3 years old, underwent surgery and chemotherapy to delay irradiation; and 29 patients with progressive disease received radiation with or without prior surgery or chemotherapy. Time to radiographic response, long-term tumor control and late sequelae were reviewed for the 29 irradiated patients. Results: The probability of at least 50% radiographic response at 24 months after irradiation was 18.1% and increased to 38.2% by 48 months and 45.9% by 60 months. By actuarial analysis, the median time for such radiographic response was 62 months. For the 29 irradiated patients, the 10-year freedom from progression and overall survival rates were 100% and 89%, respectively (median follow-up for surviving patients, 108 months). Stabilization or improvement in vision occurred in 81% of 26 evaluable irradiated patients. Conclusions: Notable radiographic response may be observed years after irradiation. Radiation therapy provides excellent long-term tumor control and vision preservation or improvement in the majority of patients with progressive chiasmal gliomas

    2010-01-01

    Significant heterogeneity of clinical presentation and disease progression exists within chronic obstructive pulmonary disease (COPD). Although FEV(1) inadequately describes this heterogeneity, a clear alternative has not emerged. The goal of phenotyping is to identify patient groups with unique...... prognostic or therapeutic characteristics, but significant variation and confusion surrounds use of the term "phenotype" in COPD. Phenotype classically refers to any observable characteristic of an organism, and up until now, multiple disease characteristics have been termed COPD phenotypes. We, however......, propose the following variation on this definition: "a single or combination of disease attributes that describe differences between individuals with COPD as they relate to clinically meaningful outcomes (symptoms, exacerbations, response to therapy, rate of disease progression, or death)."

    2013-01-01

    This guideline presents recommendations for the diagnosis and management of patients with celiac disease. Celiac disease is an immune-based reaction to dietary gluten (storage protein for wheat, barley and rye) that primarily affects the small intestine in those with a genetic predisposition and resolves with exclusion of gluten from the diet. There has been a substantial increase in the prevalence of celiac disease over the last 50 years and an increase in the rate of diagnosis in the last 10 years. Celiac disease can present with many symptoms, including typical gastrointestinal symptoms (e.g. diarrhea, steatorrhea, weight loss, bloating, flatulence, abdominal pain) and also non-gastrointestinal abnormalities (e.g. abnormal liver function tests, iron deficiency anemia, bone disease, skin disorders, and many other protean manifestations). Indeed, many individuals with celiac disease may have no symptoms at all. Celiac disease is usually detected by serologic testing of celiac-specific antibodies. The diagnosis is confirmed by duodenal mucosal biopsies. Both serology and biopsy should be performed on a gluten-containing diet. The treatment for celiac disease is primarily a gluten-free diet (GFD), which requires significant patient education, motivation, and follow-up. Non-responsive celiac disease occurs frequently, particularly in those diagnosed in adulthood. Persistent or recurring symptoms should lead to a review of the patient’s original diagnosis to exclude alternative diagnoses, a review of the GFD to ensure there is no obvious gluten contamination, and serologic testing to confirm adherence with the GFD. In addition, evaluation for disorders associated with celiac disease that could cause persistent symptoms, such as microscopic colitis, pancreatic exocrine dysfunction, and complications of celiac disease, such as enteropathy-associated lymphoma or refractory celiac disease, should be entertained. Newer therapeutic modalities are being studied in clinical

    Full Text Available Alzheimer disease (AD, Frontotemporal lobar degeneration (FTD, Amyotrophic lateral sclerosis (ALS and Parkinson disease (PD have a certain degree of clinical, pathological and molecular overlap. Previous studies indicate that causative mutations in AD and FTD/ALS genes can be found in clinical familial AD. We examined the presence of causative and low frequency coding variants in the AD, FTD, ALS and PD Mendelian genes, in over 450 families with clinical history of AD and over 11,710 sporadic cases and cognitive normal participants from North America. Known pathogenic mutations were found in 1.05% of the sporadic cases, in 0.69% of the cognitively normal participants and in 4.22% of the families. A trend towards enrichment, albeit non-significant, was observed for most AD, FTD and PD genes. Only PSEN1 and PINK1 showed consistent association with AD cases when we used ExAC as the control population. These results suggest that current study designs may contain heterogeneity and contamination of the control population, and that current statistical methods for the discovery of novel genes with real pathogenic variants in complex late onset diseases may be inadequate or underpowered to identify genes carrying pathogenic mutations.

    The diagnostic paradigm of Alzheimer disease (AD) is changing; there is a trend toward diagnosing the disease in its early stages, even before the complete syndrome of dementia is apparent. The clinical stage at which AD is usually diagnosed in our area is unknown. Therefore, the purpose of this study is to describe the clinical stages of AD patients at time of diagnosis. Multicentre, observational and cross-sectional study. Patients with probable AD according to NINCDS-ARDRA criteria, attended in specialist clinics in Spain, were included in the study. We recorded the symptom onset to evaluation and symptom onset to diagnosis intervals and clinical status of AD (based on MMSE, NPI questionnaire, and CDR scale). Participants in this study included 437 specialists representing all of Spain's autonomous communities and a total of 1,707 patients, of whom 1,694 were included in the analysis. Mean MMSE score was 17.6±4.8 (95% CI:17.4-17.9). Moderate cognitive impairment (MMSE between 10 and 20) was detected in 64% of the patients, and severe cognitive impairment (MMSEde Neurología.

    Evidence-based guidelines for the management of patients with Lyme disease were developed by the International Lyme and Associated Diseases Society (ILADS). The guidelines address three clinical questions – the usefulness of antibiotic prophylaxis for known tick bites, the effectiveness of erythema migrans treatment and the role of antibiotic retreatment in patients with persistent manifestations of Lyme disease. Healthcare providers who evaluate and manage patients with Lyme disease are the intended users of the new ILADS guidelines, which replace those issued in 2004 (Exp Rev Anti-infect Ther 2004;2:S1–13). These clinical practice guidelines are intended to assist clinicians by presenting evidence-based treatment recommendations, which follow the Grading of Recommendations Assessment, Development and Evaluation system. ILADS guidelines are not intended to be the sole source of guidance in managing Lyme disease and they should not be viewed as a substitute for clinical judgment nor used to establish treatment protocols.

    Cognitive profiles for pre-clinical Alzheimer disease (AD) can be used to identify groups of individuals at risk for disease and better characterize pre-clinical disease. Profiles or patterns of performance as pre-clinical phenotypes may be more useful than individual test scores or measures of global decline. To evaluate patterns of cognitive performance in cognitively normal individuals to derive latent profiles associated with later onset of disease using a combination of factor analysis and latent profile analysis. The National Alzheimer Coordinating Centers collect data, including a battery of neuropsychological tests, from participants at 29 National Institute on Aging-funded Alzheimer Disease Centers across the United States. Prior factor analyses of this battery demonstrated a four-factor structure comprising memory, attention, language, and executive function. Factor scores from these analyses were used in a latent profile approach to characterize cognition among a group of cognitively normal participants (N = 3,911). Associations between latent profiles and disease outcomes an average of 3 years later were evaluated with multinomial regression models. Similar analyses were used to determine predictors of profile membership. Four groups were identified; each with distinct characteristics and significantly associated with later disease outcomes. Two groups were significantly associated with development of cognitive impairment. In post hoc analyses, both the Trail Making Test Part B, and a contrast score (Delayed Recall - Trails B), significantly predicted group membership and later cognitive impairment. Latent profile analysis is a useful method to evaluate patterns of cognition in large samples for the identification of preclinical AD phenotypes; comparable results, however, can be achieved with very sensitive tests and contrast scores.

Methods: All children (less than 18 years with confirmed celiac disease diagnosed over a 6 year period at a private tertiary care health care center in Riyadh, Saudi Arabia were studied retrospectively. Information collected included demographics, clinical presentation and diagnostic modalities with serology and small intestinal histology reported by Marsh grading. Results: A total of 59 children had confirmed celiac disease. Thirty (50.8% were male. Median age was 8 years (range 1 to 16 years. The mean duration of symptoms before diagnosis was 2.3 (±1.5 years. Classical disease was present only in 30.5%, whereas 69.5% had either non-classical presentations or belonged to high risk groups for celiac disease such as those with type-1 diabetes, autoimmune thyroiditis, Down syndrome and siblings. Failure to thrive was the most common presentation followed by short stature, abdominal pain and chronic diarrhea. Anti-tissue transglutaminase antibody was positive in 91.5%, and titers were no different between those with classical and non-classical disease. All had Marsh-graded biopsy findings consistent with celiac disease. Conclusion: Children with celiac disease usually present with non-classical features. A high index of suspicion needs to be maintained to consider this disorder in the diagnostic workup of pediatric patients. High risk group should be screened early to avoid complications associated with untreated celiac disease.

    Cushing's disease is considered a rare condition characterized by the hypersecretion of the adrenocorticotropic hormone (ACTH) due to a pituitary adenoma that ultimately causes endogenous hypercortisolism by stimulating the adrenal glands. The clinical signs suggesting Cushing's disease, such as obesity, moon face, hirsutism, and facial plethora are already present on presentation. Endogenous hypercortisolism is associated with an increased risk of cardiovascular and metabolic manifestations, as well as respiratory disorders, psychiatric complications, osteoporosis and infections, leading to high rates of morbidity and mortality. It is vital to diagnose Cushing's disease as early as possible and to implement a treatment plan to lead to a successful prognosis and a low number of complications. The goal of this article was to review the clinical, diagnostic and treatment aspects of Cushing's disease using the most recent available guidelines.

    Semantic memory measures may be useful in tracking and predicting progression of Alzheimer disease. We investigated relationships among semantic memory tasks and their 1-year predictive value in women with Alzheimer disease. We conducted secondary analyses of a randomized clinical trial of raloxifene in 42 women with late-onset mild-to-moderate Alzheimer disease. We assessed semantic memory with tests of oral confrontation naming, category fluency, semantic recognition and semantic naming, and semantic density in written narrative discourse. We measured global cognition (Alzheimer Disease Assessment Scale, cognitive subscale), dementia severity (Clinical Dementia Rating sum of boxes), and daily function (Activities of Daily Living Inventory) at baseline and 1 year. At baseline and 1 year, most semantic memory scores correlated highly or moderately with each other and with global cognition, dementia severity, and daily function. Semantic memory task performance at 1 year had worsened one-third to one-half standard deviation. Factor analysis of baseline test scores distinguished processes in semantic and lexical retrieval (semantic recognition, semantic naming, confrontation naming) from processes in lexical search (semantic density, category fluency). The semantic-lexical retrieval factor predicted global cognition at 1 year. Considered separately, baseline confrontation naming and category fluency predicted dementia severity, while semantic recognition and a composite of semantic recognition and semantic naming predicted global cognition. No individual semantic memory test predicted daily function. Semantic-lexical retrieval and lexical search may represent distinct aspects of semantic memory. Semantic memory processes are sensitive to cognitive decline and dementia severity in Alzheimer disease.

    Invasive fungal diseases (IFDs) are devastating opportunistic infections that result in significant morbidity and death in a broad range of pediatric patients, particularly those with a compromised immune system. Recognizing them can be difficult, because nonspecific clinical signs and symptoms or isolated fever are frequently the only presenting features. Therefore, a high index of clinical suspicion is necessary in patients at increased risk of IFD, which requires knowledge of the pediatric patient population at risk, additional predisposing factors within this population, and the clinical signs and symptoms of IFD. With this review, we aim to summarize current knowledge regarding the recognition and clinical presentation of IFD in neonates and children. © The Author 2017.

    Full Text Available BACKGROUND: Polycystin 1 and 2, the protein abnormalities associated with autosomal dominant polycystic kidney disease (ADPKD, are also found in airway cilia and smooth muscle cells. There is evidence of increased radiologic bronchiectasis associated with ADPKD, though the clinical and functional implications of this association are unknown. We hypothesized an increased prevalence of both radiologic and clinical bronchiectasis is associated with APDKD as compared to non-ADPKD chronic kidney disease (CKD controls. MATERIALS AND METHODS: A retrospective case-control study was performed at our institution involving consecutive ADPKD and non-ADPKD chronic kidney disease (CKD patients seen over a 13 year period with both chest CT and PFT. CTs were independently reviewed by two blinded thoracic radiologists. Manually collected clinical data included symptoms, smoker status, transplant history, and PFT findings. RESULTS: Ninety-two ADPKD and 95 non-ADPKD CKD control patients were compared. Increased prevalence of radiologic bronchiectasis, predominantly mild lower lobe disease, was found in ADPKD patients compared to CKD control (19 vs. 9%, P = 0.032, OR 2.49 (CI 1.1-5.8. After adjustment for covariates, ADPKD was associated with increased risk of radiologic bronchiectasis (OR 2.78 (CI 1.16-7.12. Symptomatic bronchiectasis occurred in approximately a third of ADPKD patients with radiologic disease. Smoking was associated with increased radiologic bronchiectasis in ADPKD patients (OR 3.59, CI 1.23-12.1. CONCLUSIONS: Radiological bronchiectasis is increased in patients with ADPKD particularly those with smoking history as compared to non-ADPKD CKD controls. A third of such patients have symptomatic disease. Bronchiectasis should be considered in the differential in ADPKD patients with respiratory symptoms and smoking history.

    Cardiovascular diseases are major causes of mortality in chronic renal failure patients before and after renal transplantation. Among them, coronary disease presents a particular risk; however, risk predictors have been used to diagnose coronary heart disease. This study evaluated the frequency and importance of clinical predictors of coronary artery disease in chronic renal failure patients undergoing dialysis who were renal transplant candidates, and assessed a previously developed scoring system. Coronary angiographies conducted between March 2008 and April 2013 from 99 candidates for renal transplantation from two transplant centers in São Paulo state were analyzed for associations between significant coronary artery diseases (≥70% stenosis in one or more epicardial coronary arteries or ≥50% in the left main coronary artery) and clinical parameters. Univariate logistic regression analysis identified diabetes, angina, and/or previous infarction, clinical peripheral arterial disease and dyslipidemia as predictors of coronary artery disease. Multiple logistic regression analysis identified only diabetes and angina and/or previous infarction as independent predictors. The results corroborate previous studies demonstrating the importance of these factors when selecting patients for coronary angiography in clinical pretransplant evaluation.

    Parkinson's disease (PD) is an oxidative stress-mediated degenerative disorder. Elevated plasma homocysteine (Hcy) is frequently found in the levodopa-treated PD patients, is associated with disease progression and is a marker of oxidative stress. Whey protein is a rich source of cysteine, and branched-chain amino acids (BCAA). It has been shown that supplementation with Whey protein increases glutathione synthesis and muscle strength. In this study, we conducted a placebo-controlled, double-blind study (NCT01662414) to investigate the effects of undenatured Whey protein isolate supplementation for 6months on plasma glutathione, plasma amino acids, and plasma Hcy in PD patients. Clinical outcome assessments included the unified Parkinson's disease rating scale (UPDRS) and striatal L-3,4-dihydroxy-6-(18)F-fluorophenylalanine (FDOPA) uptake were determined before and after supplementation. 15 patients received Whey protein, and 17 received Soy protein, served as a control group. Significant increases in plasma concentration of reduced glutathione and the ratio of reduced to oxidized glutathione were found in the Whey-supplemented patients but not in a control group. This was associated with a significant decrease of plasma levels of Hcy. The plasma levels of total glutathione were not significantly changed in either group. Plasma BCAA and essential amino acids (EAA) were significantly increased in the Whey-supplemented group only. The UPDRS and striatal FDOPA uptake in PD patients were not significantly ameliorated in either group. However, significant negative correlation was observed between the UPDRS and plasma BCAA and EAA in the pre-supplemented PD patients. This study is the first to report that Whey protein supplementation significantly increases plasma reduced glutathione, the reduced to oxidized glutathione ratio, BCAAs and EAAs in patients with PD, together with a concomitant significant reduction of plasma Hcy. However, there were no significant changes in

    The number of arthroscopic rotator cuff surgeries is consistently increasing. Although generally considered successful, the reported number of retears after rotator cuff repair is substantial. Short-term clinical outcomes are reported to be rarely impaired by tendon retears, whereas to our knowledge, there is no study documenting long-term clinical outcomes and tendon integrity after arthroscopic rotator cuff repair. To investigate longitudinal long-term repair integrity and clinical outcomes after arthroscopic rotator cuff reconstruction. Case series; Level of evidence, 4. Thirty patients who underwent arthroscopic rotator cuff repair with suture anchors for a full-tendon full-thickness tear of the supraspinatus or a partial-tendon full-thickness tear of the infraspinatus were included. Two and 10 years after initial arthroscopic surgery, tendon integrity was analyzed using magnetic resonance imaging (MRI). The University of California, Los Angeles (UCLA) score and Constant score as well as subjective questions regarding satisfaction with the procedure and return to normal activity were used to evaluate short- and long-term outcomes. At the early MRI follow-up, 42% of patients showed a full-thickness rerupture, while 25% had a partial rerupture, and 33% of tendons remained intact. The 10-year MRI follow-up (129 ± 11 months) showed 50% with a total rerupture, while the other half of the tendons were partially reruptured (25%) or intact (25%). The UCLA and Constant scores significantly improved from preoperatively (UCLA total: 50.6% ± 20.2%; Constant total: 44.7 ± 10.5 points) to 2 years (UCLA total: 91.4% ± 16.0% [ P rotator cuff repair showed good clinical long-term results despite a high rate of retears. Nonetheless, intact tendons provided significantly superior clinical long-term outcomes, making the improvement of tendon healing and repair integrity important goals of future research efforts.

    Study of MRI changes may be useful in diagnosis, prognosis and better understanding of the pathophysiology of Wilson's disease (WD). We aimed to describe and correlate the MRI abnormalities of the brain with clinical features in WD. MRI evaluation was carried out in 100 patients (57 males, 43 females; mean age 19.3{+-}8.9 years) using standard protocols. All but 18 patients were on de-coppering agents. Their history, clinical manifestations and scores for severity of disease were noted. The mean duration of illness and treatment were 8.3{+-}10.8 years and 7.5{+-}7.1 years respectively. MRI of the brain was abnormal in all the 93 symptomatic patients. The most conspicuous observations were atrophy of the cerebrum (70%), brainstem (66%) and cerebellum (52%). Signal abnormalities were also noted: putamen (72%), caudate (61%), thalami (58%), midbrain (49%), pons (20%), cerebral white matter (25%), cortex (9%), medulla (12%) and cerebellum (10%). The characteristic T2-W globus pallidal hypointensity (34%), ''Face of giant panda'' sign (12%), T1-W striatal hyperintensity (6%), central pontine myelinosis (7%), and bright claustral sign (4%) were also detected. MRI changes correlated with disease severity scores (P<0.001) but did not correlate with the duration of illness. MRI changes were universal but diverse and involved almost all the structures of the brain in symptomatic patients. A fair correlation between MRI observations and various clinical features provides an explanation for the protean manifestations of the disease. (orig.)

    Akinetic mutism is thought to be an appropriate therapeutic end-point in patients with sporadic Creutzfeldt-Jakob disease (sCJD). However, prognostic factors for akinetic mutism are unclear and clinical signs or symptoms that precede this condition have not been defined. The goal of this study was to identify prognostic factors for akinetic mutism and to clarify the order of clinical sign and symptom development prior to its onset. The cumulative incidence of akinetic mutism and other clinical signs and symptoms was estimated based on Japanese CJD surveillance data (455 cases) collected from 2003 to 2008. A proportional hazards model was used to identify prognostic factors for the time to onset of akinetic mutism and other clinical signs and symptoms. Periodic synchronous discharges on electroencephalography were present in the majority of cases (93.5%). The presence of psychiatric symptoms or cerebellar disturbance at sCJD diagnosis was associated with the development of akinetic mutism [hazard ratio (HR) 1.50, 95% confidence interval (CI) 1.14-1.99, and HR 2.15, 95% CI1.61-2.87, respectively]. The clinical course from cerebellar disturbance to myoclonus or akinetic mutism was classified into three types: (i) direct path, (ii) path via pyramidal or extrapyramidal dysfunction and (iii) path via psychiatric symptoms or visual disturbance. The presence of psychiatric symptoms or cerebellar disturbance increased the risk of akinetic mutism of sCJD cases with probable MM/MV subtypes. Also, there appear to be sequential associations in the development of certain clinical signs and symptoms of this disease. © 2016 The Authors.

    Full Text Available When seeking a confirmed molecular diagnosis in the research setting, patients with one descriptive diagnosis of retinal disease could carry pathogenic variants in genes not specifically associated with that description. However, this event has not been evaluated systematically in clinical diagnostic laboratories that validate fully all target genes to minimize false negatives/positives.We performed targeted next-generation sequencing analysis on 207 ocular disease-related genes for 42 patients whose DNA had been tested negative for disease-specific panels of genes known to be associated with retinitis pigmentosa, Leber congenital amaurosis, or exudative vitreoretinopathy.Pathogenic variants, including single nucleotide variations and copy number variations, were identified in 9 patients, including 6 with variants in syndromic retinal disease genes and 3 whose molecular diagnosis could not be distinguished easily from their submitted clinical diagnosis, accounting for 21% (9/42 of the unsolved cases.Our study underscores the clinical and genetic heterogeneity of retinal disorders and provides valuable reference to estimate the fraction of clinical samples whose retinal disorders could be explained by genes not specifically associated with the corresponding clinical diagnosis. Our data suggest that sequencing a larger set of retinal disorder related genes can increase the molecular diagnostic yield, especially for clinically hard-to-distinguish cases.

    Early treatment of rheumatoid arthritis (RA) results in better long-term outcomes. However, the optimal therapeutic window has not been clearly established. To determine the clinical outcome of Puerto Ricans with RA receiving early treatment with conventional and/or biologic disease-modifying anti-rheumatic drugs (DMARDs) based on the American College of Rheumatology (ACR) definition of early RA. A cross-sectional study was performed in a cohort of Puerto Ricans with RA. Demographic features, clinical manifestations, disease activity, functional status, and pharmacotherapy were determined. Early treatment was defined as the initiation of DMARDs (conventional and/or biologic) in less than 6 months from the onset of symptoms attributable to RA. Patients who received early (disease duration was 14.9 years and 337 (87.0%) patients were women. One hundred and twenty one (31.3%) patients received early treatment. In the multivariate analysis adjusted for age and sex, early treatment was associated with better functional status, lower probability of joint deformities, intra-articular injections and joint replacement surgeries, and lower scores in the physician's assessments of global health, functional impairment and physical damage of patients. Using the ACR definition of early RA, this group of patients treated with DMARDs within 6 months of disease had better long-term outcomes with less physical damage and functional impairment.

    Objective To describe long-term clinical and serological outcome in all systemic lupus erythematosus (SLE) domains in SLE patients with hand arthralgia (HA) and joint ultrasound (JUS) inflammatory abnormalities, and to compare them with asymptomatic SLE patients with normal JUS. Methods SLE patients with HA who presented JUS inflammatory abnormalities ('cases') and SLE patients without HA who did not exhibit JUS abnormalities at baseline ('controls') were included. All SLE clinical and serological domain involvement data were collected. End follow-up clinical activity and damage scores (systemic lupus erythematosus disease activity index (SLEDAI), Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR)) were recorded. JUS inflammatory abnormalities were defined based on the Proceedings of the Seventh International Consensus Conference on Outcome Measures in Rheumatology Clinical Trials (OMERACT-7) definitions. Statistical analyses were carried out to compare 'cases' and 'controls'. Results A total of 35 patients were recruited. The 'cases', n = 18/35, had a higher incidence of musculoskeletal involvement (arthralgia and/or arthritis) through the follow-up period (38.9% vs 0%, p = 0.008) and received more hydroxychloroquine (61.1% vs 25.0%, p = 0.034) and methotrexate (27.8% vs 0%, p = 0.046) compared to 'controls', n = 17/35. Other comparisons did not reveal any statistical differences. Conclusions We found SLE patients with arthralgia who presented JUS inflammatory abnormalities received more hydroxychloroquine and methotrexate, mainly due to persistent musculoskeletal involvement over time. JUS appears to be a useful technique for predicting worse musculoskeletal outcome in SLE patients.

    Full Text Available The failure of several Phase II/III clinical trials in Alzheimer’s disease (AD with drugs targeting β-amyloid accumulation in the brain fuelled an increasing interest in alternative treatments against tau pathology, including approaches targeting tau phosphatases/kinases, active and passive immunization, and anti-tau aggregation. The most advanced tau aggregation inhibitor (TAI is methylthioninium (MT, a drug existing in equilibrium between a reduced (leuco-methylthioninium and oxidized form (MT+. MT chloride (methylene blue was investigated in a 24-week Phase II clinical trial in 321 patients with mild to moderate AD that failed to show significant positive effects in mild AD patients, although long-term observations (50 weeks and biomarker studies suggested possible benefit. The dose of 138 mg/day showed potential benefits on cognitive performance of moderately affected AD patients and cerebral blood flow in mildly affected patients. Further clinical evidence will come from the large ongoing Phase III trials for the treatment of AD and the behavioral variant of frontotemporal dementia on a new form of this TAI, more bioavailable and less toxic at higher doses, called TRx0237. More recently, inhibitors of tau acetylation are being actively pursued based on impressive results in animal studies obtained by salsalate, a clinically used derivative of salicylic acid.

    Objective: To investigate the clinical Significance of determination of serum thyroid stimulating hormone receptor antibody (TRAb) levels in patients with thyroid diseases, especially in patients with Graves' disease. Methods: Serum TRAb levels were determined with radio-receptor assay (RRA) in 302 patients with various thyroid diseases and 52 controls. Results: In patients with Graves' disease before treatment (n=62) the positive rate of TRAb was 86.3%. In patients with Graves' diseases improved after treatment (n=60), the positive rate was 74.5%; in those clinically cured (n=68) the positive rate was 32.1%. In 58 patients with Graves' disease who relapsed after apparently cure, the positive rate of TRAb rose to 90.3 %. However, there were no positive TRAb cases in 23 patients with simple goiter and 31 patients with benign thyroid adenomas. Also, there were no positive TRAb cases in the controls. Conclusion: TRAb levels correspond well with the severity of Graves' disease. (authors)

    Lombardia GENS is a multicentre prospective study aimed at diagnosing 5 single-gene disorders associated with stroke (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, Fabry disease, MELAS [mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes], hereditary cerebral amyloid angiopathy, and Marfan syndrome) by applying diagnostic algorithms specific for each clinically suspected disease We enrolled a consecutive series of patients with ischemic or hemorrhagic stroke or transient ischemic attack admitted in stroke units in the Lombardia region participating in the project. Patients were defined as probable when presenting with stroke or transient ischemic attack of unknown etiopathogenic causes, or in the presence of young age at onset, or positive familial history or of specific clinical features. Patients fulfilling diagnostic algorithms specific for each monogenic disease (suspected) were referred for genetic analysis. In 209 patients (57.4±14.7 years), the application of the disease-specific algorithm identified 227 patients with possible monogenic disease. Genetic testing identified pathogenic mutations in 7% of these cases. Familial history of stroke was the only significant specific feature that distinguished mutated patients from nonmutated ones. The presence of cerebrovascular risk factors did not exclude a genetic disease. In patients prescreened using a clinical algorithm for monogenic disorders, we identified monogenic causes of events in 7% of patients in comparison to the 1% to 5% prevalence reported in previous series. © 2016 American Heart Association, Inc.

    The definition of Parkinson's disease (PD) is changing with the expansion of clinical phenomenology and improved understanding of environmental and genetic influences that impact on the pathogenesis of the disease at the cellular and molecular level. This had led to debate and discussion with as yet, no general acceptance of the direction that change should take either at the level of diagnosis or of what should and should not be sheltered under an umbrella of PD. This article is one contribution to this on-going discussion. There are two different themes running through the article--widening the definition of PD/LBD/synucleinopathies and the heterogeneity that exists within PD itself from a clinical, pathological and genetic perspective. The conclusion reached is that in the future, further diagnostic categories will need to be recognized. These are likely to include--Parkinson's syndrome, Parkinson's syndrome likely to be Lewy body PD, clinical PD (defined by QSBB criteria), Lewy body disease (PD, LBD, REM SBD) and synucleinopathies (including LBD, MSA).

    Clinical studies have shown an association between long-term anticholinergic (AC) drug exposure and Alzheimer's disease (AD) pathogenesis, which has been primarily investigated in Parkinson's disease (PD). However, long-term AC exposure as a risk factor for developing neurodegenerative disorders and the exact mechanisms and potential for disease progression remain unclear. Here, we have addressed the issue using trihexyphenidyl (THP), a commonly used AC drug in PD patients, to determine if THP can accelerate AD-like neurodegenerative progression and study potential mechanisms involved. Male Sprague-Dawley rats (SD) were intraperitoneally injected with THP (0.3 and 1.0 mg/kg) or normal saline (NS) for 7 months. Alterations in cognitive and behavioral performance were assessed using the Morris water maze (MWM) and open field tests. After behavior tests, whole genome oligo microarrays, quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR), immunohistochemistry, and immunofluorescence-confocal were used to investigate the global mechanisms underlying THP-induced neuropathology with aging. Compared with NS controls, the MWM test results showed that THP-treated rats exhibited significantly extended mean latencies during the initial 3 months of testing; however, this behavioral deficit was restored between the fourth and sixth month of MWM testing. The same tendencies were confirmed by MWM probe and open field tests. Gene microarray analysis identified 68 (47 %) upregulated and 176 (53 %) downregulated genes in the "THP-aging" vs. "NS-aging" group. The most significant populations of genes downregulated by THP were the immune response-, antigen processing and presentation-, and major histocompatibility complex (MHC)-related genes, as validated by qRT-PCR. The decreased expression of MHC class I in THP-treated aging brains was confirmed by confocal analysis. Notably, long-term THP treatment primed hippocampal and cortical microglia to

    Lundquist, Andrew L; Nigwekar, Sagar U

    2016-03-01

    The review summarizes recent studies on chronic kidney disease-mineral bone disorders, with a focus on new developments in disease management. The term chronic kidney disease-mineral bone disorder has come to describe an increasingly complex network of alterations in minerals and skeletal disorders that contribute to the significant cardiovascular morbidity and mortality seen in patients with chronic kidney disease and end stage renal disease. Clinical studies continue to suggest associations with clinical outcomes, yet current clinical trials have failed to support causality. Variability in practice exists as current guidelines for management of mineral bone disorders are often based on weak evidence. Recent studies implicate novel pathways for therapeutic intervention in clinical trials. Mineral bone disorders in chronic kidney disease arise from alterations in a number of molecules in an increasingly complex physiological network interconnecting bone and the cardiovascular system. Despite extensive associations with improved outcomes in a number of molecules, clinical trials have yet to prove causality and there is an absence of new therapies available to improve patient outcomes. Additional clinical trials that can incorporate the complexity of mineral bone disorders, and with the ability to intervene on more than one pathway, are needed to advance patient care.

Methodology: All children aged 0 - 12 years having characteristic clinical features along with diagnostic hallmark of any MLDs were included in this study and data were collected on a pre-designed proforma. After appropriate management and discharge, all patients were followed-up for next 6 months. Results: Fifty one children with mean age 4.34 +- 3.78 years (range 2 days +- 12 years), male: female ratio 1.55:1, were studied. The etiologies were Wilson's disease (33.33%, n = 17); glycogen storage disorder (23.53%, n = 12); galactosemia (19.61%, n = 10); non-alcoholic fatty liver disease (11.76%, n = 6); Gaucher disease (5.88%, n = 3); mucopolysaccharidoses (3.92%, n = 2) and familial hyperlipoproteinemia type-I (1.96%, n = 1). Jaundice (n = 24) and hepatomegaly (n = 47), was the commonest symptom and sign respectively. Of the 17 non-responders, most were Wilson's disease (n = 7) cases. There was statistical difference in outcome with respect to INR > 1.3 at diagnosis (p = 0.026). Conclusion: High index of suspicion, early detection and screening, simple dietary modification and cost effective drugs along with good compliance are sufficient to treat and even prevent evolution of most causes of the MLDs.

    Gaucher disease is the most frequent lysosomal storage disease and the most prevalent genetic disease among Ashkenazi Jews. Gaucher disease type 1 is characterized by marked variability of the phenotype and by the absence of neuronopathic involvement. To test the hypothesis that this phenotypic variability was due to genetic compounds of several different mutant alleles, 161 symptomatic patients with Gaucher disease type 1 (> 90% Ashkenazi Jewish) were analyzed for clinical involvement, and their genotypes were determined. Qualitative and quantitative measures of disease involvement included age at onset of the disease manifestations, hepatic and splenic volumes, age at splenectomy, and severity of bony disease. High statistically significant differences (P < .005) were found in each clinical parameter in patients with the N370S/N370S genotype compared with those patients with the N370S/84GG, N370S/L444P, and N370/ genotypes. The symptomatic N370S homozygotes had onset of their disease two to three decades later than patients with the other genotypes. In addition, patients with the latter genotypes have much more severely involved livers, spleens, and bones and had a higher incidence of splenectomy at an earlier age. These predictive genotype analyses provide the basis for genetic care delivery and therapeutic recommendations in patients affected with Gaucher disease type 1. 38 refs., 1 fig., 4 tabs.

    Clinical evidence is important for improving the treatment of patients by health care providers. In the study of cardiovascular diseases, large-scale clinical trials involving thousands of participants are required to evaluate the risks of cardiac events and/or death. The problems encountered in conducting the Japanese Acute Myocardial Infarction Prospective (JAMP) study highlighted the difficulties involved in obtaining the financial and infrastructural resources necessary for conducting large-scale clinical trials. The objectives of the current study were: 1) to clarify the current funding and infrastructural environment surrounding large-scale clinical trials in cardiovascular and metabolic diseases in Japan, and 2) to find ways to improve the environment surrounding clinical trials in Japan more generally. We examined clinical trials examining cardiovascular diseases that evaluated true endpoints and involved 300 or more participants using Pub-Med, Ichushi (by the Japan Medical Abstracts Society, a non-profit organization), websites of related medical societies, the University Hospital Medical Information Network (UMIN) Clinical Trials Registry, and clinicaltrials.gov at three points in time: 30 November, 2004, 25 February, 2007 and 25 July, 2009. We found a total of 152 trials that met our criteria for 'large-scale clinical trials' examining cardiovascular diseases in Japan. Of these, 72.4% were randomized controlled trials (RCTs).

     Objectives: To characterize the clinical presentations and diagnosis including serological tests and histopathological findings in children with celiac disease. Methods: All children (less than 18 years) with confirmed celiac disease diagnosed over a 6 year period at a private tertiary care health care center in Riyadh,  Saudi Arabia were studied retrospectively. Information collected included demographics, clinical presentation and diagnostic modalities with serology and small intestinal histology reported by Marsh grading. Results: A total of 59 children had confirmed celiac disease. Thirty (50.8%) were male. Median age was 8 years (range 1 to 16 years). The mean duration of symptoms before diagnosis was 2.3 (±1.5) years. Classical disease was present only in 30.5%, whereas 69.5% had either non-classical presentations or belonged to high risk groups for celiac disease such as those with type-1 diabetes, autoimmune thyroiditis, Down syndrome and siblings. Failure to thrive was the most common presentation followed by short stature, abdominal pain and chronic diarrhea. Anti-tissue transglutaminase antibody was positive in 91.5%, and titers were no different between those with classical and non-classical disease. All had Marsh-graded biopsy findings consistent with celiac disease. Conclusion: Children with celiac disease usually present with non-classical features. A high index of suspicion needs to be maintained to consider this disorder in the diagnostic workup of pediatric patients. High risk group should be screened early to avoid complications associated with untreated celiac disease.

    Epidemiological studies suggest that tea consumption decreases cardiovascular risk, but the mechanisms of benefit remain undefined. Endothelial dysfunction has been associated with coronary artery disease and increased oxidative stress. Some antioxidants have been shown to reverse endothelial dysfunction, and tea contains antioxidant flavonoids. Methods and Results-- To test the hypothesis that tea consumption will reverse endothelial dysfunction, we randomized 66 patients with proven coronary artery disease to consume black tea and water in a crossover design. Short-term effects were examined 2 hours after consumption of 450 mL tea or water. Long-term effects were examined after consumption of 900 mL tea or water daily for 4 weeks. Vasomotor function of the brachial artery was examined at baseline and after each intervention with vascular ultrasound. Fifty patients completed the protocol and had technically suitable ultrasound measurements. Both short- and long-term tea consumption improved endothelium- dependent flow-mediated dilation of the brachial artery, whereas consumption of water had no effect (Peffect on endothelium-independent nitroglycerin-induced dilation. An equivalent oral dose of caffeine (200 mg) had no short-term effect on flow-mediated dilation. Plasma flavonoids increased after short- and long-term tea consumption. Short- and long-term black tea consumption reverses endothelial vasomotor dysfunction in patients with coronary artery disease. This finding may partly explain the association between tea intake and decreased cardiovascular disease events.

    Brain amyloid β (Aβ) deposition and neurodegeneration have been documented in about 50-60% of cognitively healthy elderly individuals (aged 60 years or older). The long-term cognitive consequences of the presence of Alzheimer's disease pathology and neurodegeneration, and whether they have an independent or synergistic effect on cognition, are unclear. We aimed to characterise the long-term clinical and cognitive trajectories of healthy elderly individuals using a two-marker (Alzheimer's disease pathology and neurodegeneration) imaging construct. Between Nov 3, 2006, and Nov 25, 2014, 573 cognitively healthy individuals in Melbourne and Perth, Australia, (mean age 73·1 years [SD 6·2]; 58% women) were enrolled in the Australian Imaging, Biomarker and Lifestyle (AIBL) study. Alzheimer's disease pathology (A) was determined by measuring Aβ deposition by PET, and neurodegeneration (N) was established by measuring hippocampal volume using MRI. Individuals were categorised as A(-)N(-), A(+)N(-), A(+)N(+), or suspected non-Alzheimer's disease pathophysiology (A(-)N(+), SNAP). Clinical progression, hippocampal volume, standard neuropsychological tests, and domain-specific and global cognitive composite scores were assessed over 6 years of follow-up. Linear mixed effect models and a Cox proportional hazards model of survival were used to evaluate, compare, and contrast the clinical, cognitive, and volumetric trajectories of patients in the four AN categories. 50 (9%) healthy individuals were classified as A(+)N(+), 87 (15%) as A(+)N(-), 310 (54%) as A(-)N(-), and 126 (22%) as SNAP. APOE ε4 was more frequent in participants in the A(+)N(+) (27; 54%) and A(+)N(-) (42; 48%) groups than in the A(-)N(-) (66; 21%) and SNAP groups (23; 18%). The A(+)N(-) and A(+)N(+) groups had significantly faster cognitive decline than the A(-)N(-) group (0·08 SD per year for AIBL-Preclinical AD Cognitive Composite [PACC]; p<0·0001; and 0·25; p<0·0001; respectively).

    Subjective memory is commonly considered to be a unidimensional measure. However, theories of performance-based memory suggest that subjective memory could be divided into more than one dimension. To divide subjective memory into theoretically related components of memory and explore the relationship to disease. In this study, various aspects of self-reported memory were studied with respect to demographics and diseases in the third wave of the HUNT epidemiological study in middle Norway. The study included all individuals 55 years of age or older, who responded to a nine-item questionnaire on subjective memory and questionnaires on health (n=18 633). A principle component analysis of the memory items resulted in two memory components; the criterion used was an eigenvalue above 1, which accounted for 54% of the total variance. The components were interpreted as long-term memory (LTM; the first component; 43% of the total variance) and short-term memory (STM; the second component; 11% of the total variance). Memory impairment was significantly related to all diseases (except Bechterew's disease), most strongly to brain infarction, heart failure, diabetes, cancer, chronic obstructive pulmonary disease and whiplash. For most diseases, the STM component was more affected than the LTM component; however, in cancer, the opposite pattern was seen. Subjective memory impairment as measured in HUNT contained two components, which were differentially associated with diseases. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Clinical experts' cognitive mechanisms for managing complexity have implications for the design of future innovative healthcare systems. The purpose of the study is to examine the constituents of decision complexity and explore the cognitive strategies clinicians use to control and adapt to their information environment. We used Cognitive Task Analysis (CTA) methods to interview 10 Infectious Disease (ID) experts at the University of Utah and Salt Lake City Veterans Administration Medical Center. Participants were asked to recall a complex, critical and vivid antibiotic-prescribing incident using the Critical Decision Method (CDM), a type of Cognitive Task Analysis (CTA). Using the four iterations of the Critical Decision Method, questions were posed to fully explore the incident, focusing in depth on the clinical components underlying the complexity. Probes were included to assess cognitive and decision strategies used by participants. The following three themes emerged as the constituents of decision complexity experienced by the Infectious Diseases experts: 1) the overall clinical picture does not match the pattern, 2) a lack of comprehension of the situation and 3) dealing with social and emotional pressures such as fear and anxiety. All these factors contribute to decision complexity. These factors almost always occurred together, creating unexpected events and uncertainty in clinical reasoning. Five themes emerged in the analyses of how experts deal with the complexity. Expert clinicians frequently used 1) watchful waiting instead of over- prescribing antibiotics, engaged in 2) theory of mind to project and simulate other practitioners' perspectives, reduced very complex cases into simple 3) heuristics, employed 4) anticipatory thinking to plan and re-plan events and consulted with peers to share knowledge, solicit opinions and 5) seek help on patient cases. The cognitive strategies to deal with decision complexity found in this study have important

    Full Text Available BACKGROUND: The ClinicalTrials.gov registry provides information regarding characteristics of past, current, and planned clinical studies to patients, clinicians, and researchers; in addition, registry data are available for bulk download. However, issues related to data structure, nomenclature, and changes in data collection over time present challenges to the aggregate analysis and interpretation of these data in general and to the analysis of trials according to clinical specialty in particular. Improving usability of these data could enhance the utility of ClinicalTrials.gov as a research resource. METHODS/PRINCIPAL RESULTS: The purpose of our project was twofold. First, we sought to extend the usability of ClinicalTrials.gov for research purposes by developing a database for aggregate analysis of ClinicalTrials.gov (AACT that contains data from the 96,346 clinical trials registered as of September 27, 2010. Second, we developed and validated a methodology for annotating studies by clinical specialty, using a custom taxonomy employing Medical Subject Heading (MeSH terms applied by an NLM algorithm, as well as MeSH terms and other disease condition terms provided by study sponsors. Clinical specialists reviewed and annotated MeSH and non-MeSH disease condition terms, and an algorithm was created to classify studies into clinical specialties based on both MeSH and non-MeSH annotations. False positives and false negatives were evaluated by comparing algorithmic classification with manual classification for three specialties. CONCLUSIONS/SIGNIFICANCE: The resulting AACT database features study design attributes parsed into discrete fields, integrated metadata, and an integrated MeSH thesaurus, and is available for download as Oracle extracts (.dmp file and text format. This publicly-accessible dataset will facilitate analysis of studies and permit detailed characterization and analysis of the U.S. clinical trials enterprise as a whole. In

    Full Text Available &lt;B&gt;Purpose:&lt;/B&gt; The purpose of this prospective case-control study was to survey the detection rate of respiratory viruses in children with Kawasaki disease (KD by using multiplex reverse transcriptasepolymerase chain reaction (RT-PCR, and to investigate the clinical implications of the prevalence of respiratory viruses during the acute phase of KD. &lt;B&gt;Methods:&lt;/B&gt; RT-PCR assays were carried out to screen for the presence of respiratory syncytial virus A and B, adenovirus, rhinovirus, parainfluenza viruses 1 to 4, influenza virus A and B, metapneumovirus, bocavirus, coronavirus OC43/229E and NL63, and enterovirus in nasopharyngeal secretions of 55 KD patients and 78 control subjects. &lt;B&gt;Results:&lt;/B&gt; Virus detection rates in KD patients and control subjects were 32.7% and 30.8%, respectively (P=0.811. However, there was no significant association between the presence of any of the 15 viruses and the incidence of KD. Comparisons between the 18 patients with positive RT-PCR results and the other 37 KD patients revealed no significant differences in terms of clinical findings (including the prevalence of incomplete presentation of the disease and coronary artery diameter. &lt;B&gt;Conclusion:&lt;/B&gt; A positive RT-PCR for currently epidemic respiratory viruses should not be used as an evidence against the diagnosis of KD. These viruses were not associated with the incomplete presentation of KD and coronary artery dilatation.

    Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are neurodegenerative diseases with overlap in clinical presentation, neuropathology, and genetic underpinnings. The molecular basis for the overlap of these disorders is not well established. We performed a comparative unbiased mass spectrometry-based proteomic analysis of frontal cortical tissues from postmortem cases clinically defined as ALS, FTD, ALS and FTD (ALS/FTD), and controls. We also included a subset of patients with the C9orf72 expansion mutation, the most common genetic cause of both ALS and FTD Our systems-level analysis of the brain proteome integrated both differential expression and co-expression approaches to assess the relationship of these differences to clinical and pathological phenotypes. Weighted co-expression network analysis revealed 15 modules of co-expressed proteins, eight of which were significantly different across the ALS-FTD disease spectrum. These included modules associated with RNA binding proteins, synaptic transmission, and inflammation with cell-type specificity that showed correlation with TDP-43 pathology and cognitive dysfunction. Modules were also examined for their overlap with TDP-43 protein-protein interactions, revealing one module enriched with RNA-binding proteins and other causal ALS genes that increased in FTD/ALS and FTD cases. A module enriched with astrocyte and microglia proteins was significantly increased in ALS cases carrying the C9orf72 mutation compared to sporadic ALS cases, suggesting that the genetic expansion is associated with inflammation in the brain even without clinical evidence of dementia. Together, these findings highlight the utility of integrative systems-level proteomic approaches to resolve clinical phenotypes and genetic mechanisms underlying the ALS-FTD disease spectrum in human brain. © 2017 The Authors.

    Purpose. To retrospectively evaluate the 10 year follow-up results in patients who had 'kissing' self-expanding stent aortic bifurcation reconstruction. Methods. Forty-three patients were treated with 'kissing' self-expanding stents for aortoiliac occlusive disease. Early follow-up with clinical and ankle brachial pressure indices (ABPI) was performed at 3, 6, 12, and 24 months and with intra-arterial digital subtraction angiography at 12-24 months; clinical and angiographic follow-up was performed for symptom recurrence up to 10 years after treatment. Retrospective record review was performed to assess mortality, clinical patency, angiographic patency, and secondary assisted patency of both stents and downstream peripheral vessels at 5 and 10 years follow-up. Results. The 2 year primary angiographic and secondary assisted stent patencies were 89% and 93%, respectively. At 10 years follow-up in 40 patients the mortality was 38% (due to myocardial infarction, stroke, chronic renal failure, malignancy, and liver failure). At 5 and 10 years follow-up the primary clinical stent patency was 82% and 68%, and the secondary assisted stent patency 93% and 86%, respectively. At 5 and 10 years, the distal vessel patency was 86% and 72%, and the secondary assisted distal vessel patency treated by surgical or endovascular techniques was 94% and 88%, respectively. At 10 years there was no limb loss. Conclusion. The long-term (10 year) results of aortic bifurcation arterial self-expanding stent placement in patients with arterial occlusive disease show a 10 year primary stent patency rate of 68% but a secondary assisted patency rate of 86%. In addition there is a high overall mortality due to other cardiovascular causes and the rate of distal disease progression and loss of patency is similar to the loss of stent patency rate

    Vedolizumab (VDZ), an α4β7 anti-integrin antibody, is efficacious in the induction and maintenance of remission in ulcerative colitis (UC) and Crohn's disease (CD). In the GEMINI long-term safety study, enrolled patients received 4-weekly VDZ. Upon completion, patients were switched to 8-weekly VDZ in Australia. The clinical success rate of treatment de-escalation for patients in remission on VDZ has not been described previously. To determine the proportion of patients who relapsed after switching from 4 to 8-weekly VDZ, the mean time to relapse, and the recapture rate when switching back to 8-weekly dosing. This was a retrospective, observational, multicenter study of patients previously recruited into GEMINI long-term safety in Australia. Data on the demographics and biochemical findings were collected. There were 34 patients [23 men, mean age 49.1 (±13.1) years] and their mean disease duration was 17.6 (±8.5) years. The mean 4-weekly VDZ infusion duration was 286.5 (±48.8) weeks. A total of five (15%) patients relapsed on dose-interval increase (4/17 UC, 1/17 CD) at a median duration from dose interval lengthening to flare of 14 weeks (interquartile range=6-25). Eighty percent (4/5) of patients re-entered remission following dose-interval decrease back to 4-weekly. No clinical predictors of relapse could be determined because of the small cohort size. The risk of patients relapsing when switching from 4 to 8-weekly VDZ ∼15% and is similar between CD and UC. Dose-interval decrease recaptures 80% of patients who relapsed. Therapeutic drug monitoring of VDZ may be of clinical relevance.

    Recurrence of hypercortisolemia after initial treatment of Cushing disease (CD) is more common than previously thought, with a third of patients suffering a recurrence over their lifetime. Awareness of this high rate and delayed timeline (sometimes decades) of potential recurrence is critical and patients with CD should be monitored at regular intervals throughout their lives. In this manuscript, we review the complex evaluation needed for defining CD remission versus persistent disease after surgery, and focus on challenges in diagnosing early recurrent hypercortisolemia. Late night salivary cortisol appears to be an earlier predictor of recurrence when compared with urinary free cortisol (UFC) excretion. We also review the criteria suggested to define recurrence of hypercortisolemia in patients treated with medical therapy. Further research is needed to determine the optimal way to evaluate a patient with CD recurrence as well as the riskbenefit ratio of treatment in early, mild recurrent disease.

    Advances in medical and surgical management of congenital heart disease have changed the prognosis of infants and children with cardiac defects, so that an increasing number of patients reach adolescence and adult life, even those with complex defects. Recent data suggest that the number of adults with congenital heart disease, either repaired or not, approaches the number of children with the disorder. A cure is rarely achieved and ongoing surveillance and management in conjunction with specialists in this highly specialized field is mandatory to provide optimal care for patients. The profile of this patient population is going to change over the next few decades. Ideally specialist units should be established in appropriate geographic locations; patients need to be concentrated for expertise, experience, and optimal management. Less specialized regional centers and outpatient clinics in districts in connection with grown-up congenital heart disease units should be created. Specialist units should accept responsibility for educating the professionals, training the specialists, and sharing particular skills between each other. Guidelines and recommendations should help physicians to make decision in their daily practice. However, the final judgment regarding the care of an individual patient must be made by his/her physician. This article will briefly discuss some aspects of these dedicated guidelines and how they influence the clinical daily practice.

The predictive values of baseline CSA and PD for clinical outcomes were determined with multivariate logistic regression models.Short-term and long-term follow-up data were available for 111 (82.2% and 105 (77.8% patients, respectively. There was a final diagnosis of CTS in 84 patients (125 wrists. Regression analysis revealed that the CSA, measured at the carpal tunnel inlet, predicted short-term clinical improvement according to BQ in CTS patients undergoing carpal tunnel surgery (OR 1.8, p = 0.05, but not in patients treated conservatively. Neither CSA nor PD assessments predicted short-term improvement of painVAS, physVAS or DASH, nor was any of the ultrasound parameters useful for the prediction of long-term clinical outcomes.Ultrasound assessment of the median nerve at the carpal tunnel inlet may predict short-term clinical improvement in CTS patients undergoing carpal tunnel release, but long-term outcomes are unrelated to ultrasound findings.

    Full Text Available OBJECTIVES: To characterize the clinical, laboratory, and anthropometric profile of a sample of Brazilian patients with glycogen storage disease type I managed at an outpatient referral clinic for inborn errors of metabolism. METHODS: This was a cross-sectional outpatient study based on a convenience sampling strategy. Data on diagnosis, management, anthropometric parameters, and follow-up were assessed. RESULTS: Twenty-one patients were included (median age 10 years, range 1-25 years, all using uncooked cornstarch therapy. Median age at diagnosis was 7 months (range, 1-132 months, and 19 patients underwent liver biopsy for diagnostic confirmation. Overweight, short stature, hepatomegaly, and liver nodules were present in 16 of 21, four of 21, nine of 14, and three of 14 patients, respectively. A correlation was found between height-for-age and BMI-for-age Z-scores (r = 0.561; p = 0.008. CONCLUSIONS: Diagnosis of glycogen storage disease type I is delayed in Brazil. Most patients undergo liver biopsy for diagnostic confirmation, even though the combination of a characteristic clinical presentation and molecular methods can provide a definitive diagnosis in a less invasive manner. Obesity is a side effect of cornstarch therapy, and appears to be associated with growth in these patients.

    This work aimed at studying the salivary gland disease (SGD) as it relates to associated factors, such as persistent generalised lymphadenopathy (PGL), lymphocytic interstitial pneumonia (LIP), clinical and immunological features of AIDS, and salivary flow rate and pH, as well as at exploring the relationship between the clinical diagnosis and the imaging diagnosis by ultrasound (US) examination of the parotid glands. Information regarding the observation of parotid gland enlargement, PGL, LIP, and clinical and immunological features of AIDS was gathered from medical records, and a saliva sample for unstimulated salivary flow rate and pH measurement was collected from 142 children aged 3 through 10 years treated at the Department of Infectious Diseases of Joana de Gusmão Children's Hospital, Florianópolis, SC, Brazil. High-resolution ultrasonography was performed in 58 children. Pearson's chi-square test and t-test were used to evaluate the association between the variables. A significant association was found between SGD and LIP. Ultrasound revealed a 50% higher incidence of SGD that was not reported in the patients' records. US examination proved to be essential for the correct diagnosis and monitoring of the progression of HIV/SGD. © 2014 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Relationships between duplex findings and data on health-related quality of life (QoL) to assess long-term results of treatment of varicose veins and chronic venous insufficiency (CVI) are not well known. The goal of this review was to correlate duplex findings and QoL assessments in clinical studies with long-term follow-up. A review of the English language literature on PUBMED revealed 17 clinical studies, including 9 randomized controlled trials (RCTs), 6 prospective, and 2 retrospective studies that included patients with at least 5-year follow-up after endovenous laser ablation (EVLA), radiofrequency ablation (RFA), ultrasound-guided foam sclerotherapy (UGFS), and traditional superficial venous surgery. At 5 years, great saphenous vein (GSV) occlusion rate on duplex ultrasound ranged from 66% to 82% for EVLA, from 62% to 92% for RFA, from 41% to 58% for UGFS and from 54% to 85% for surgery. Freedom from GSV reflux rates were 82% and 84%, respectively for EVLA and surgery, and ranged between 84% and 95% for RFA. Significant improvements were observed in several domains of generic QoL and in most domains of venous disease-specific QoL, irrespective of the treatment. In at least one RCT, CIVIQ scores correlated well with abnormal duplex findings in patients who underwent treatment with UGFS. In another RCT, long-term AVVQ was significantly better after surgery as compared with UGFS similar to results of duplex findings. Analysis of the available literature confirmed that all four techniques were effective in the abolishment of reflux or obliteration of the GSV. Moreover, well-designed RCTs with large sample size are needed to produce robust long-term data on clinical outcome after treatment of varicose veins and CVI and to better understand the relationships between duplex-derived data and QoL assessments. © The Author(s) 2016.

    Objective: This study aimed to use a systematic approach to evaluate the current utilization, safety, and effectiveness of cell therapies for neurological diseases in human. And review the present regulations, considering United States (US) as a representative country, for cell transplantation in neurological disease and discuss the challenges facing the field of neurology in the coming decades. Methods:A detailed search was performed in systematic literature reviews of cellular‐based therapies in neurological diseases, using PubMed, web of science, and clinical trials. Regulations of cell therapy products used for clinical trials were searched from the Food and Drug Administration (FDA) and the National Institutes of Health (NIH). Results: Seven most common types of cell therapies for neurological diseases have been reported to be relatively safe with varying degrees of neurological recovery. And a series of regulations in US for cellular therapy was summarized including preclinical evaluations, sourcing material, stem cell manufacturing and characterization, cell therapy product, and clinical trials. Conclusions:Stem cell‐based therapy holds great promise for a cure of such diseases and will value a growing population of patients. However, regulatory permitting activity of the US in the sphere of stem cells, technologies of regenerative medicine and substitutive cell therapy are selective, theoretical and does not fit the existing norm and rules. Compiled well‐defined regulations to guide the application of stem cell products for clinical trials should be formulated.

    Full Text Available Neurodegenerative diseases represent a heterogeneous group of neurological conditions primarily involving dementia, motor neuron disease and movement disorders. They are mostly related to different pathophysiological processes, notably in family forms in which the clinical and genetic heterogeneity are lush. In the last decade, much knowledge has been acumulated about the genetics of neurodegenerative diseases, making it essential in cases of motor neuron disease and frontotemporal dementia the repeat expansions of C9orf72 gene. This review analyzes the main clinical, radiological and genetic aspects of the phenotypes related to the hexanucleotide repeat expansions (GGGGCC of C9orf72 gene. Future studies will aim to further characterize the neuropsychological, imaging and pathological aspects of the extra-motor features of motor neuron disease, and will help to provide a new classification system that is both clinically and biologically relevant.

    There are multiple autosomal recessive disorders in which carriers may be at risk for other diseases. This observation calls into question the previous understanding that carriers of autosomal recessive disorders escape clinical consequences. We also know that childhood genetic conditions may have adult disease counterparts (Zimran et al., The Israel Medical Association Journal: IMAJ, 16(11), 723-724, 2014). Individuals who have Gaucher disease and carriers of the disorder are at increased risk for a seemingly unrelated and complex neurological condition, Parkinson disease. Parkinson disease is, in part, caused by the same mutations in the GBA gene that lead to Gaucher disease, and the two conditions are thought to have shared pathophysiology. Briefly reviewed are how these two diseases historically became linked, where their paths cross, potential problems and considerations in disclosure of the link, and current guidelines and research in this area. Genetic counseling experience with a large Parkinson disease cohort is used as a starting point to question the state of clinical and nonclinical practice in disclosing this unusual connection We conclude that more research and discussion are needed to inform practice regarding the crossroads of Gaucher and Parkinson disease.

    Diagnosis of interstitial lung diseases is generally arrived at by clinical history, physical examination, and radiologic images, especially high-resolution CT-scanning. It is important to note that, while these diseases have different clinical and histological characteristics, they share a basic pattern of abnormal lung function. With regard to high-resolution tomography, the characteristics of these diseases are similar, although there are specific differences that can be helpful for correct diagnosis. These diseases have severe consequences on respiratory gas exchange. These alterations, combined with other abnormalities of lung function, cause the signs and symptoms and have an impact on quality of life. The use of physiologic parameters is not only helpful for diagnosis, but can also assess severity, help to define the consequences of treatment, and aid in the follow-up. Although some pulmonary function tests can remain completely normal with severe radiographic findings, 10% of patients have impaired lung function before radiologic changes. High-resolution tomography is an essential imaging tool for the study of these patients. This is true not only for diagnosis, but also with regard to clinical parameters and follow-up. Its prognostic use is continually gaining importance. In this article we assess the clinical use of pulmonary function tests and high-resolution tomography in interstitial lung diseases.

    2016-10-01

    No disease-modifying therapies (DMT) for neurodegenerative diseases (NDs) have been established, particularly for Alzheimer's disease (AD) and Parkinson's disease (PD). It is unclear why candidate drugs that successfully demonstrate therapeutic effects in animal models fail to show disease-modifying effects in clinical trials. To overcome this hurdle, patients with homogeneous pathologies should be detected as early as possible. The early detection of AD patients using sufficiently tested biomarkers could demonstrate the potential usefulness of combining biomarkers with clinical measures as a diagnostic tool. Cerebrospinal fluid (CSF) biomarkers for NDs are being incorporated in clinical trials designed with the aim of detecting patients earlier, evaluating target engagement, collecting homogeneous patients, facilitating prevention trials, and testing the potential of surrogate markers relative to clinical measures. In this review we summarize the latest information on CSF biomarkers in NDs, particularly AD and PD, and their use in clinical trials. The large number of issues related to CSF biomarker measurements and applications has resulted in relatively few clinical trials on CSF biomarkers being conducted. However, the available CSF biomarker data obtained in clinical trials support the advantages of incorporating CSF biomarkers in clinical trials, even though the data have mostly been obtained in AD trials. We describe the current issues with and ongoing efforts for the use of CSF biomarkers in clinical trials and the plans to harness CSF biomarkers for the development of DMT and clinical routines. This effort requires nationwide, global, and multidisciplinary efforts in academia, industry, and regulatory agencies to facilitate a new era.

    There is limited long-term comparative clinical outcome data concerning angiography- versus intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in non-complex left main coronary artery (LMCA) disease treated with the single stenting technique in the drug-eluting stent (DES) era.The aim of this study was to investigate whether angiography-guided stenting is comparable to IVUS-guided stenting during 3-year clinical follow-up periods in patients with non-complex LM disease treated with the single stenting technique.A total of 196 patients treated with either angiography-guided (n = 74) or IVUS-guided (n = 122) PCI were included. The primary outcome was the occurrence of major adverse cardiac events (MACE) defined as total death, non-fatal myocardial infarction (MI), target lesion revascularization (TLR), target vessel revascularization (TVR), and non-target vessel revascularization (Non-TVR). To adjust for any potential confounders, propensity score (PS) adjusted analysis was performed.During 3-year follow-up, the PS adjusted Cox-proportional hazard ratio (HR) was not significantly different between the two groups for total death, cardiac death, and MI. Also, TLR and the combined rates of TVR and non-TVR were not significantly different. Finally, MACE was not significantly different between the two groups (HR: 0.63, 95% Confidence interval (CI): 0.33-1.17; P = 0.149).Angiography-guided PCI for non-complex LMCA diseases treated with the single stenting technique showed comparable results compared with IVUS-guided PCI in reducing clinical events during 3-year clinical follow-up in the DES era. Although IVUS guided PCI is the ideal strategy, angiography-guided PCI can be an option for LMCA PCI in some selected cases.

    A small proportion of cases seen in neurodegenerative conditions such as amyotrophic lateral sclerosis (ALS), Parkinson\\'s disease and Alzheimer disease are familial. These familial cases are usually clinically indistinguishable from sporadic cases. Identifying familial cases is important both in terms of clinical guidance for family members and for gene discovery.

    2018-06-14

    This is an in-depth review on the mechanism of action, clinical utility, and drug-drug interactions of colchicine in the management of pericardial disease. Recent evidence about therapeutic targets on pericarditis has demonstrated that NALP3 inflammasome blockade is the cornerstone in the clinical benefits of colchicine. Such benefits extend from acute and recurrent pericarditis to transient constriction and post-pericardiotomy syndrome. Despite the increased utilization of colchicine in cardiovascular medicine, safety concerns remains unsolved regarding the long-term use of colchicine in the cardiac patient. Moreover, recent evidence has demonstrated that numerous cardiovascular medications, ranging from antihypertensive medication to antiarrhythmics, are known to interact with the CYP3A4 and/or P-gp system increasing the toxicity potential of colchicine. The use of adjunctive colchicine in the management of inflammatory pericardial diseases is standard of care in current practice. It is advised that a careful medication reconciliation with emphasis on pharmacokinetic is completed before prescribing colchicine in order to avoid harmful interaction by finding an alternative regimen or adjusting colchicine dosing.

    Impulse control and related disorders (ICRDs) are clinically complications in Parkinson's disease (PD). However, the clinical characteristics of ICRDs in Chinese PD patients were rarely reported. We aimed to explore the prevalence and the clinical profile of ICRDs in Chinese patients with PD. 142 Chinese PD patients were consecutively enrolled. The symptoms of ICRDs were assessed with the Questionnaire for Impulsive-Compulsive Disorders. The clinical characteristics of patients with ICRDs and without ICRDs were compared. ICRDs were present in 31% of our patients. The most common ICRDs were compulsive medication use (11.3%) and punding (9.2%); the least frequent were walkabout (1.4%). Variables independently associated with ICRDs were earlier onset of the disease (≤55 years), severe cognitive impairment (MMSE 10-20), the dose of dopamine agonist (>1 mg/d) and dyskinesia. ICRDs was commonly found in Chinese PD patients. Earlier onset of the disease, the dose of dopamine agonist, severe cognitive impairment and dyskinesia are independent factors associated with ICRDs. Our results will be benefit for clinicians to assess the risk of developing ICRDs before delivering dopaminergic medication.

    Melatonin is a molecule with numerous properties applicable to the treatment of neurological diseases. Among these properties are the following: potent scavenger of oxygen and nitrogen reactive species, anti-inflammatory features, immuno-enhancing nature, and modulation of circadian rhythmicity. Furthermore, low concentrations of melatonin are usually found in patients with neurological diseases and mental disorders. The positive results obtained in experimental models of diverse pathologies, including diseases of the nervous system (e.g., Alzheimer's disease, Parkinson's disease, multiple sclerosis, amyotrophic lateral sclerosis, Huntington's disease, epilepsy, headaches, etc.) as well as mental and behavioural disordes (e.g., autism spectrum disorders, attention-deficit hyperactivity disorders, etc.), have served as a basis for the design of clinical trials to study melatonin's possible usefulness in human pathology, although the satisfactory results obtained from the laboratory "bench" are not always applicable to the patient's "bedside". In this article, we review those papers describing the results of the administration of melatonin to humans for various therapeutic purposes in the field of neuropathology. Clinical trials with strong methodologies and appropriate doses of melatonin are necessary to support or reject the usefulness of melatonin in neurological diseases.

    HPV is related to a number of cancer types, causing a considerable burden in both genders in Europe. Female vaccination programs can substantially reduce the incidence of HPV-related diseases in women and, to some extent, men through herd immunity. The objective was to estimate the incremental benefit of vaccinating boys and girls using the quadrivalent HPV vaccine in Europe versus girls-only vaccination. Incremental benefits in terms of reduction in the incidence of HPV 6, 11, 16 and 18-related diseases (including cervical, vaginal, vulvar, anal, penile, and head and neck carcinomas and genital warts) were assessed. The analysis was performed using a model constructed in Microsoft®Excel, based on a previously-published dynamic transmission model of HPV vaccination and published European epidemiological data on incidence of HPV-related diseases. The incremental benefits of vaccinating 12-year old girls and boys versus girls-only vaccination was assessed (70% vaccine coverage were assumed for both). Sensitivity analyses around vaccine coverage and duration of protection were performed. Compared with screening alone, girls-only vaccination led to 84% reduction in HPV 16/18-related carcinomas in females and a 61% reduction in males. Vaccination of girls and boys led to a 90% reduction in HPV 16/18-related carcinomas in females and 86% reduction in males versus screening alone. Relative to a girls-only program, vaccination of girls and boys led to a reduction in female and male HPV-related carcinomas of 40% and 65%, respectively and a reduction in the incidence of HPV 6/11-related genital warts of 58% for females and 71% for males versus girls-only vaccination. In Europe, the vaccination of 12-year old boys and girls against HPV 6, 11, 16 and 18 would be associated with substantial additional clinical benefits in terms of reduced incidence of HPV-related genital warts and carcinomas versus girls-only vaccination. The incremental benefits of adding boys vaccination are

    Full Text Available Introduction: Chronic obstructive pulmonary disease is characterized by progressive and partially reversible obstruction of pulmonary airflow. Aim: To characterize swallowing in patients with chronic obstructive pulmonary disease and correlate the findings with the degree chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, and smoking. Method: We conducted a prospective cohort study of 19 patients (12 men and 7 women; age range, 50–85 years with confirmed medical diagnosis of chronic obstructive pulmonary disease. This study was performed in 2 stages (clinical evaluation and functional assessment using nasolaryngofibroscopy on the same day. During both stages, vital signs were checked by medical personnel. Results: Clinical evaluation of swallowing in all patients showed the clinical signs of cough. The findings of nasolaryngofibroscopy highlighted subsequent intraoral escape in 5 patients (26.5%. No patient had tracheal aspiration. There was no association of subsequent intraoral escape with degree of chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, or smoking. Conclusion: In patients with chronic obstructive pulmonary disease, there was a prevalence of oral dysphagia upon swallowing and nasolaryngofibroscopy highlighted the finding of subsequent intraoral escape. There was no correlation between intraoral escape and the degree of chronic obstructive pulmonary disease, heart and respiratory rate, oxygen saturation, or smoking.

    Purpose: The aim of this study was to evaluate retrospectively the effectiveness and toxicity of post-lumpectomy whole-breast radiation therapy delivered with prone positioning. Methods and Materials: Between September 1992 and August 2004, 245 women with 248 early-stage invasive or in situ breast cancers were treated using a prone breast board. Photon fields treated the whole breast to 46 to 50.4 Gy with standard fractionation. The target volume was clinically palpable breast tissue; no attempt was made to irradiate chest wall lymphatics. Tumor bed boosts were delivered in 85% of cases. Adjuvant chemotherapy and hormonal therapy were administered to 42% and 62% of patients, respectively. Results: After a median follow-up of 4.9 years, the 5 year actuarial true local and elsewhere ipsilateral breast tumor recurrence rates were 4.8% and 1.3%, respectively. The 5-year actuarial rates of regional nodal recurrence and distant metastases were 1.6% and 7.4%. Actuarial disease-free, disease-specific, and overall survival rates at 5 years were 89.4%, 97.3%, and 93%, respectively. Treatment breaks were required by 2.4% of patients. Grade 3 acute dermatitis and edema were each limited to 2% of patients. Only 4.9% of patients complained of acute chest wall discomfort. Chronic Grade 2 to 3 skin and subcutaneous tissue toxicities were reported in 4.4% and 13.7% of patients, respectively. Conclusions: Prone position breast radiation results in similar long-term disease control with a favorable toxicity profile compared with standard supine tangents. The anatomic advantages of prone positioning may contribute to improving the therapeutic ratio of post-lumpectomy radiation by improving dose homogeneity and minimizing incidental cardiac and lung dose

    The index case of the Ebola virus disease epidemic in West Africa is believed to have originated in Guinea. By June 2014, Guinea, Liberia, and Sierra Leone were in the midst of a full-blown and complex global health emergency. The devastating effects of this Ebola epidemic in West Africa put the global health response in acute focus for urgent international interventions. Accordingly, in October 2014, a World Health Organization high-level meeting endorsed the concept of a phase 2/3 clinical trial in Liberia to study Ebola vaccines. As a follow-up to the global response, in November 2014, the Government of Liberia and the US Government signed an agreement to form a research partnership to investigate Ebola and to assess intervention strategies for treating, controlling, and preventing the disease in Liberia. This agreement led to the establishment of the Joint Liberia-US Partnership for Research on Ebola Virus in Liberia as the beginning of a long-term collaborative partnership in clinical research between the two countries. In this article, we discuss the methodology and related challenges associated with the implementation of the Ebola vaccines clinical trial, based on a double-blinded randomized controlled trial, in Liberia. © The Author(s) 2016.

    Full Text Available Background Huntington's disease (HD is an autosomal dominant hereditary progressive neurodegenerative disorder with a distinct phenotype characterized by chorea, dementia, cognitive and affective impairment. There are selective neural cell loss and atrophy in the caudate and putamen. Dr. George Huntington firstly described the disease accurately and insightfully, which led to a widespread recognition of the inherited chorea that now bears his name. Huntington disease gene (IT15 locus on chromosome 4p16.3, and encompasses 67 exons with a trinucleotide repeat (CAG in the first exon. The CAG repeat length is highly polymorphic in the population and expanded on at least one chromosome of individuals with HD. Clinically, patient with HD are often onset in adulthood. Juvenile-onset HD is relatively rare. Adult-onset HD patients usually have a CAG expansion from 40 to 55 whereas those with juvenile-onset greater than 60 which are often inherited from the father. We investigated the clinical features of a juvenile-onset case with Huntington disease and dynamic mutation of his family. Methods The CAG repeats of IT15 gene were detected using polymerase chain reaction and capillary electrophoresis in 115 individuals with preliminary diagnosis as Huntington disease. The repeat numbers of some samples carried expanded or intermediate alleles were verified by the pMD18-T vector clone sequencing. Results Fragment analysis showed that one juvenile-onset case presenting with cognitive dysfunction and hypokinesis carried 15/68 CAG repeats of IT15. His father carried 17/37 and mother carried 15/17. Conclusion 1 The juvenile-onset case of HD presented with different clinical features compared with adult-onset cases. The typical signs of adult-onset cases include progressive chorea, rigidity and dementia. The most common sign of juvenile-onset Huntington disease is cognitive decline. 2 The dynamic mutation of IT15 gene expansion of the CAG repeats in the

    Full Text Available BACKGROUND: SPARC is a matricellular protein involved in tissue remodelling, cell migration and angiogenesis, while forkhead box P3 (FOXP3 protein functions as a transcription factor involved in immune cell regulation. Both SPARC and FOXP3 can play an anti-tumorigenic role in cancer progression. The aim was to determine if SPARC, FOXP3, CD8 and CD45RO expression levels are associated with colorectal cancer (CRC stage, disease outcome and long-term cancer-specific survival (CSS in stage II and III CRC. METHODS AND FINDINGS: SPARC expression was initially assessed in 120 paired normal and stage I-IV CRCs. Subsequently, approximately 1000 paired patient samples of stage II or III CRCs in tissue microarrays were stained for SPARC, FOXP3, CD8 or CD45RO. Proportional hazards modelling assessed correlations between these markers and clinicopathological data, including disease outcome and cancer specific survival (CSS. Both SPARC and FOXP3 expression were significantly greater in CRC than normal colon (p<0.0001. High SPARC expression correlated with good disease outcome (≥60 mths without disease recurrence, p = 0.0039 and better long-term CSS in stage II CRC (<0.0001. In stage III CRC, high SPARC expression correlated with better long-term CSS (p<0.0001 and less adjuvant chemotherapy use (p = 0.01. High FOXP3 correlated with a good disease outcome, better long-term CSS and less adjuvant chemotherapy use in stage II (p<0.0037, <0.0001 and p = 0.04 respectively, but not in stage III CRC. High CD8 and CD45RO expression correlated with better disease outcome in stage II CRC, and better CSS, but the differences were not as marked as for SPARC and FOXP3. CONCLUSIONS: These data suggest that high SPARC and FOXP3 are associated with better disease outcome in stage II CRC and may be prognostic indicators of CSS. Further assessment of whether these markers predict patients at high risk of recurrence with stage II CRC and functional studies of these

    Purpose IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition that can affect nearly any organ. No detailed clinical and laboratory assessments have been reported in large numbers of patients with IgG4-RD diagnoses established by strict clinicopathological correlation. Methods We reviewed the baseline features of 125 patients with biopsy-proven disease. The diagnosis was confirmed by pathology review according to consensus diagnostic criteria. Disease activity and damage were assessed by the IgG4-RD Responder Index (RI). Flow cytometry was used to assess levels of circulating plasmablasts. Results Of the 125 patients, 103 had active disease and 86 were on no treatment. Only 51% of the patients with active disease had elevated serum IgG4 concentrations. However, patients with active disease and elevated serum IgG4 concentrations were older, had a higher RI, a greater number of organs involved, lower complement levels, higher absolute eosinophil counts, and higher IgE levels compared to those with active disease but normal serum IgG4 (PIgG4+ plasmablast level and RI (R=0.45, P=0.003) was stronger than that of total plasmablasts and RI. Seventy-six (61%) of the patients were male, but no significant differences according to gender were observed with regard to disease severity, organ involvement, or serum IgG4 concentrations. Glucocorticoids failed to produce sustained remission in the majority of patients. Conclusion Nearly 50% of this patient cohort with biopsy-proven, clinically-active IgG4-RD had normal serum IgG4 concentrations. Serum IgG4 elevation identify a subset with more inflammatory features. IgG4+ plasmablasts correlate well with disease activity. PMID:25988916

    There have been very few studies on inflammatory bowel disease (IBD) in Sri Lanka. This study was undertaken to determine the clinical presentation and whether a western style diet or infection with geo-helminths were associated with the condition. Three questionnaires were given to the patients: one relating to diet, one relating to clinical presentation and one relating to quality of life. The disease was confirmed endoscopically and histologically. Faeces were examined for parasites. Forty four patients were enrolled (43-ulcerative colitis; 1-Crohn's Disease). All but one had ulcerative colitis. Most had no family history of disease. The peak age of onset was 21-40 y and 63% gave a history of more than 6 months symptoms prior to diagnosis. Clinical presentation was similar to cases in western countries although milder with less severe life-events. None of them had undergone surgery. All patients ate a rice-based diet and none ate bread made of refined flour. Only 2 patient was infected with a geo-helminth. Eating bread made of refined flour is not related to development of IBD in these patients. The prevalence of geo-helminths in the study population corresponded to the general population average. Delay in diagnosis occurs because of an initial assumption that the cause of symptoms is infective. A National Register of non-infectious gastrointestinal disease would aid the epidemiology and allocation of funding to this inflammatory condition.

    Guillain-Barre Syndrome (GBS) is a life-threatening condition in which patients may present to the Emergency Department in respiratory distress leading to death. The early identification and treatment of such a condition is paramount in preventing mortality. While there are many infections associated with GBS, the association with Lyme disease is uncommon. Through our case we aim to highlight Borrelia burgdorferi as an important antecedent infection associated with the development of GBS. In this case we report a 31-year-old male who was diagnosed with Lyme disease and GBS with relevant clinical presentation including progressive numbness and weakness in bilateral hands and feet for the past 1week along with areflexia. Initiation of medical therapy with intravenous immunoglobulin and parenteral ceftriaxone resulted in resolution of his symptoms. The treatment of both diseases early can help prevent further central nervous complications leading to high morbidity and mortality. Copyright © 2017 Elsevier Inc. All rights reserved.

    Echocardiographic screening for rheumatic heart disease in asymptomatic children may result in early diagnosis and prevent progression. Physician-led screening is not feasible in Malawi. Task shifting to mid-level providers such as clinical officers may enable more widespread screening. Hypothesis With short-course training, clinical officers can accurately screen for rheumatic heart disease using focussed echocardiography. A total of eight clinical officers completed three half-days of didactics and 2 days of hands-on echocardiography training. Clinical officers were evaluated by performing screening echocardiograms on 20 children with known rheumatic heart disease status. They indicated whether children should be referred for follow-up. Referral was indicated if mitral regurgitation measured more than 1.5 cm or there was any measurable aortic regurgitation. The κ statistic was calculated to measure referral agreement with a paediatric cardiologist. Sensitivity and specificity were estimated using a generalised linear mixed model, and were calculated on the basis of World Heart Federation diagnostic criteria. The mean κ statistic comparing clinical officer referrals with the paediatric cardiologist was 0.72 (95% confidence interval: 0.62, 0.82). The κ value ranged from a minimum of 0.57 to a maximum of 0.90. For rheumatic heart disease diagnosis, sensitivity was 0.91 (95% confidence interval: 0.86, 0.95) and specificity was 0.65 (95% confidence interval: 0.57, 0.72). There was substantial agreement between clinical officers and paediatric cardiologists on whether to refer. Clinical officers had a high sensitivity in detecting rheumatic heart disease. With short-course training, clinical officer-led echo screening for rheumatic heart disease is a viable alternative to physician-led screening in resource-limited settings.

    Full Text Available Celiac disease (CD is a complex polygenic disorder, which involves genetic factors human leukocyte complex (HLA and non-HLA genes, environmental factors, innate and adoptive immunity, and a robust chronic T-mediated autoimmune component. The main goal of the present monograph is to define a methodological approach for the disease, characterized by frequent late diagnosis, in order for the physician to become aware of the disease management, the diversity of the clinical presentation itself and in different patients. A unique attention is payed to the specific diagnostic tests to define a correct and accurate application of them, and in addition, to disease follow-up and possible complications. Moreover, a dedicated space is assigned to refractory CD, to potential CD and non-celiac gluten sensitivity. Legislative aspects of the celiac disease in Italy are addressed, too. The celiac disease guidelines and their evaluation by means of Appraisal of Guidelines, Research and Evaluation II instrument allow us to classify the different recommendations and to apply them according to the stakeholders’ involvement, pertinence, methodological accuracy, clarity and publishing independence. Finally, the most current scientific evidence is taken into account to create a complete updated monograph.

    To summarize the clinical features of different racial patients with celiac disease (CD) and analyze the disease prevalence, diagnosis and treatment in Chinese population. All the patients were diagnosed as CD and enrolled in Beijing United Family Hospital between January 2005 and July 2015.Clinical data including nationality, age, symptoms, endoscopic and pathological findings, outcome were collected and compared in patients from different countries. A total of 87 patients were enrolled including 63 Caucasians, 18 Asian patients and 6 Middle East patients.The peak age of disease onset was 40-60 years old.Patients with typical symptoms such as chronic diarrhea and weight loss only accounted for 20.7%(18/87) and 9.2%(8/87) respectively.Some patients presented with nonspecific symptoms such as abdominal pain and bloating [32.2%(28/87)], even constipation [5.7%(5/87)].13.8%(12/87) patients were previously diagnosed as irritable bowel syndrome.The incidence of abdominal pain, bloating, diarrhea and constipation between Asians and Caucasians had no statistical significance (P>0.05); but the proportions of weight loss, growth retardation, iron deficiency anemia and dermatitis herpetiformis in Asian group were significantly higher than that in Caucasian group (Pceliac disease antibodies in 47 patients turned negative from 6-9 months after GFD treatment, while 34 patients turned negative from 12-18 months after GFD.All patients reported disease remission to some extent.After 1 year GFD treatment, the pathology of endoscopic intestinal biopsy in 8 patients showed significant improvement of villous atrophy and lymphocyte infiltration. CD patients with typical clinical manifestations are not the majority.Serological celiac disease antibodies (AGA, EMA and tTGA) have a high diagnostic value.GFD treatment is effective on majority of celiac patients.Clinical manifestations, endoscopy, intestinal pathology, and response to GFD in Chinese patients are not the same as Caucasians

    Interstitial lung diseases (ILDs) are among the most serious complications associated with systemic rheumatic diseases, and lead to significant morbidity and mortality; they may also be the first manifestation of connective tissue diseases (CTDs). The aim of this narrative review is to summarise the data concerning the pathogenesis of CTD/ILD and its distinguishing features in different rheumatic diseseas. Areas covered: The pathogenesis, clinical aspects and treatment of ILD associated with rheumatic systemic diseases and CTDs were reviewed by searching the PubMed, Medline, and Cochrane Library databases for papers published between 1995 and February 2017 using combinations of words or terms. Articles not written in English were excluded. Expert commentary: The management of CTD-ILD is challenging because of the lack of robust data regarding the treatments used, the heterogeneity of the diseases themselves, and the scarcity of well-defined outcome measures. Treatment decisions are often made clinically on the basis of functional, radiographic progression, and exacerbating factors such as age and the burden of comorbidities. Given the complexities of diagnosis and the paucity of treatment trials, the management of CTD patients with ILD requires multidisciplinary collaboration between rheumatologists and pulmonologists in CTD-ILD clinics.

    Full Text Available Malnutrition has been associated with increased morbidity and mortality. The objective of this study was to determine the nutritional status and micronutrient levels of hospitalized patients in an infectious disease clinic and investigate their association with adverse clinical outcomes. The nutritional status of the study participants was assessed using the Nutritional Risk Screening 2002 (NRS 2002 and micronutrient levels and routine biochemical parameters were tested within the first 24 h of the patient’s admission. The incidence of zinc, selenium, thiamine, vitamin B6, vitamin B12 deficiency were 66.7% (n = 40, 46.6% (n = 29, 39.7% (n = 27, 35.3% (n = 24, 14.1% (n = 9, respectively. Selenium levels were significantly higher in patients with urinary tract infections, but lower in soft tissue infections. Copper levels were significantly higher in patients with soft tissue infections. In the Cox regression models, lower albumin, higher serum lactate dehydrogenase levels and higher NRS-2002 scores were associated with increased death. Thiamine, selenium, zinc and vitamin B6 deficiencies but not chromium deficiencies are common in infectious disease clinics. New associations were found between micronutrient levels and infection type and their adverse clinical outcomes. Hypoalbuminemia and a high NRS-2002 score had the greatest accuracy in predicting death, systemic inflammatory response syndrome and sepsis on admission.

    To study the equine deep stromal abscesses (DSA) with focus on the duration of the corneal disease, medical treatment, season of presentation, clinical appearance, and the degree of corneal vascularization. Equine DSA diagnosed, biopsied, and surgically treated at the University of Florida Veterinary Medical Center (UFVMC) from 2004 to 2009 were identified. The medical record, clinical photographic images, and microbiology results for each case were evaluated. Frequency and prevalence calculation as well as qualitative data analysis was performed for clinical and microbiological data. Fifty-one equine DSA were included in the study. Spring (March, April, May; 33.4%) and winter (December, January, February; 31.4%) were the most common seasons for DSA presentation. The 51 cases were divided into four categories of focal opacity from their clinical appearance: focal yellow (45.2%), focal white (23.5%), diffuse yellow/white (23.5%), and focal pink (7.8%). 5.9% of the DSA (n = 3) were culture positive for fungal growth, whereas 17.6% were positive for bacterial growth (n = 9). No association between short-/long-term systemically administered NSAID treatment and the corneal vascular response to the corneal lesion could be appreciated. Equine DSA most often present in the spring and winter in the subtropical environment of the state of Florida (USA). The clinical appearance may have a connection with the etiology and pathogenesis of the equine DSA. No connection between short- or long-term systemically administered NSAID and the degree of corneal vascularization of the DSA was noted. © 2013 American College of Veterinary Ophthalmologists.

  4. Clinical value of natriuretic peptides in chronic kidney disease.

    Science.gov (United States)

    Santos-Araújo, Carla; Leite-Moreira, Adelino; Pestana, Manuel

    2015-01-01

    According to several lines of evidence, natriuretic peptides (NP) are the main components of a cardiac-renal axis that operate in clinical conditions of decreased cardiac hemodynamic tolerance to regulate sodium homeostasis, blood pressure and vascular function. Even though it is reasonable to assume that NP may exert a relevant role in the adaptive response to renal mass ablation, evidence gathered so far suggest that this contribution is probably complex and dependent on the type and degree of the functional mass loss. In the last years NP have been increasingly used to diagnose, monitor treatment and define the prognosis of several cardiovascular (CV) diseases. However, in many clinical settings, like chronic kidney disease (CKD), the predictive value of these biomarkers has been questioned. In fact, it is now well established that renal function significantly affects the plasmatic levels of NP and that renal failure is the clinical condition associated with the highest plasmatic levels of these peptides. The complexity of the relation between NP plasmatic levels and CV and renal functions has obvious consequences, as it may limit the predictive value of NP in CV assessment of CKD patients and be a demanding exercise for clinicians involved in the daily management of these patients. This review describes the role of NP in the regulatory response to renal function loss and addresses the main factors involved in the clinical valorization of the peptides in the context of significant renal failure.

  5. Roles of Vascular and Metabolic Components in Cognitive Dysfunction of Alzheimer disease: Short- and Long-term Modification by Non-genetic Risk Factors

    Naoyuki eSato

    2013-11-01

    Full Text Available It is well known that a specific set of genetic and non-genetic risk factors contributes to the onset of Alzheimer disease (AD. Non-genetic risk factors include diabetes, hypertension in mid-life, and probably dyslipidemia in mid-life. This review focuses on the vascular and metabolic components of non-genetic risk factors. The mechanisms whereby non-genetic risk factors modify cognitive dysfunction are divided into four components, short- and long-term effects of vascular and metabolic factors. These consist of 1 compromised vascular reactivity, 2 vascular lesions, 3 hypo/hyperglycemia, and 4 exacerbated AD histopathological features, respectively. Vascular factors compromise cerebrovascular reactivity in response to neuronal activity and also cause irreversible vascular lesions. On the other hand, representative short-term effects of metabolic factors on cognitive dysfunction occur due to hypoglycemia or hyperglycemia. Non-genetic risk factors also modify the pathological manifestations of AD in the long-term. Therefore, vascular and metabolic factors contribute to aggravation of cognitive dysfunction in AD through short-term and long-term effects. Beta-amyloid could be involved in both vascular and metabolic components. It might be beneficial to support treatment in AD patients by appropriate therapeutic management of non-genetic risk factors, considering the contributions of these four elements to the manifestation of cognitive dysfunction in individual patients, though all components are not always present. It should be clarified how these four components interact with each other. To answer this question, a clinical prospective study that follows up clinical features with respect to these four components: 1 functional MRI or SPECT for cerebrovascular reactivity, 2 MRI for ischemic lesions and atrophy, 3 clinical episodes of hypoglycemia and hyperglycemia, 4 amyloid-PET and tau-PET for pathological features of AD, would be required.

    Purpose: To analyze long-term outcome and prognostic factors for high-risk prostate cancer defined by National Comprehensive Cancer Network criteria treated with high-dose radiotherapy and androgen deprivation in a single institution. Methods and Materials: A total of 306 patients treated between 1995 and 2007 in a radiation dose-escalation program fulfilled the National Comprehensive Cancer Network high-risk criteria. Median International Commission on Radiation Units and Measurements radiation dose was 78 Gy (range, 66.0-84.1 Gy). Long-term androgen deprivation (LTAD) was administered in 231 patients, short-term androgen deprivation (STAD) in 59 patients, and no hormones in 16 patients. The Phoenix (nadir plus 2 ng/mL) consensus definition was used for biochemical control. Multivariate analysis was performed to determine the independent prognostic impact of clinical and treatment factors. Median follow-up time was 64 months (range, 24-171 months). Results: The actuarial overall survival at 5 and 10 years was 95.7% and 89.8%, respectively, and the corresponding biochemical disease-free survival (bDFS) was 89.5% and 67.2%, respectively. Fourteen patients (4.6%) developed distant metastasis. Multivariate analysis showed that Gleason score >7 (p = 0.001), pretreatment prostate-specific antigen (PSA) level >20 ng/mL (p = 0.037), higher radiation dose (p = 0.005), and the use of adjuvant LTAD vs. STAD (p = 0.011) were independent prognostic factors affecting bDFS in high-risk disease. The 5-year bDFS for patients treated with LTAD plus radiotherapy dose >78 Gy was 97%. Conclusions: For high-risk patients the present series showed that the use of LTAD in conjunction with higher doses (>78 Gy) of radiotherapy was associated with improved biochemical tumor control. We observed that the presence of Gleason sum >7 and pretreatment PSA level >20 ng/mL in the same patient represents a 6.8 times higher risk of PSA failure. These men could be considered for clinical trials with

    The modern era of drug development for Alzheimer’s disease began with the proposal of the cholinergic hypothesis of memory impairment and the 1984 research criteria for Alzheimer’s disease. Since then, despite the evaluation of numerous potential treatments in clinical trials, only four cholinesterase inhibitors and memantine have shown sufficient safety and efficacy to allow marketing approval at an international level. Although this is probably because the other drugs tested were ineffective, inadequate clinical development methods have also been blamed for the failures. Here we review the development of treatments for Alzheimer’s disease during the past 30 years, considering the drugs, potential targets, late-stage clinical trials, development methods, emerging use of biomarkers and evolution of regulatory considerations in order to summarize advances and anticipate future developments. We have considered late-stage Alzheimer’s disease drug development from 1984 to 2013, including individual clinical trials, systematic and qualitative reviews, meta-analyses, methods, commentaries, position papers and guidelines. We then review the evolution of drugs in late clinical development, methods, biomarkers and regulatory issues. Although a range of small molecules and biological products against many targets have been investigated in clinical trials, the predominant drug targets have been the cholinergic system and the amyloid cascade. Trial methods have evolved incrementally: inclusion criteria have largely remained focused on mild to moderate Alzheimer’s disease criteria, recently extending to early or prodromal Alzheimer disease or ‘mild cognitive impairment due to Alzheimer’s disease’, for drugs considered to be disease modifying. The duration of trials has remained at 6 to 12 months for drugs intended to improve symptoms; 18- to 24-month trials have been established for drugs expected to attenuate clinical course.

    Full Text Available Abstract Background In recent years there has been increasing recognition that the pattern of presentation of coeliac disease may be changing. The classic sprue syndrome with diarrhoea and weight loss may be less common than the more subtle presentations of coeliac disease such as an isolated iron deficiency anaemia. As a result, the diagnosis of this treatable condition is often delayed or missed. Recent serologic screening tests allow non-invasive screening to identify most patients with the disease and can be applied in patients with even subtle symptoms indicative of coeliac disease. Both benign and malignant complications of coeliac disease can be avoided by early diagnosis and a strict compliance with a gluten free diet. Aim The aim of this study is to evaluate the trends in clinical presentation of patients diagnosed with adult coeliac disease. In addition, we studied the biochemical and serological features and the prevalence of associated conditions in patients with adult coeliac disease. Methods This is an observational, retrospective, cross-sectional review of the medical notes of 32 adult patients attending the specialist coeliac clinic in a district general hospital. Results Anaemia was the most common mode of presentation accounting for 66% of patients. Less than half of the patients had any of the classical symptoms of coeliac disease and 25% had none of the classical symptoms at presentation. Anti-gliadin antibodies, anti-endomysial antibody and anti-tissue transglutaminase showed 75%, 68% and 90% sensitivity respectively. In combination, serology results were 100% sensitive as screening tests for adult coeliac disease. Fifty nine percent patients had either osteoporosis or osteopenia. There were no malignant complications observed during the follow up of our patients. Conclusion Most adults with coeliac disease have a sub clinical form of the disease and iron deficiency anaemia may be its sole presenting symptom. Only a minority

    We evaluated long-term magnetic resonance imaging (MRI) features of Knee Osteochondral Autologous Transplantation (OAT)-Mosaicplasty and correlated MRI findings and clinical outcome. Twenty-four patients (mean age 29.9 ± 8.7, 70.8% male) undergoing arthroscopic OAT between 1997 and 2000 were prospectively enrolled. The International Cartilage Repair Society (ICRS)/International Knee Documentation Committee (IKDC) scores and Tegner scores were employed for clinical evaluation. The magnetic resonance observation of cartilage repair tissue (MOCART) was utilized for description and assessment of the repair tissue. Median follow up was 113 months (interquartile range [IQR] 106-122). MRI showed good survival of grafted cartilage in 62.5% of patients. The integration of the graft was complete in 75% of cases, while the repaired tissue was intact in 62.5% and had an homogeneous structure in 70.8%. The MOCART score significantly correlated with objective and subjective scores (p = 0.003 and p = 0.002). Contrastingly, overall MOCART showed no correlation with the Tegner score. MRI revealed to be a powerful tool for non-invasive long-term assessment of OAT.

    Dilazep tablets (300 mg/day) were administered to 9 patients with ischemic heart disease for more than 2 months. Stress myocardial scintigraphy was performed before and after the treatment to examine the clinical effect of this drug on the heart. The improvement rate of subjective symptoms was 57% (4/7 cases). No significant difference was observed in double product by the ergometer before and after the treatment, nor were any significant changes observed in ST by Master's two-step exercise test in any patient. The pre- to posttreatment improvement rate of myocardial uptake, demonstrated by stress myocardial scintigraphy, was 89% (8/9 cases). Thus, Dilazep tablets seemed to increase the blood flow in the ischemic area of the myocardium during exercise in ischemic heart disease. (Chiba, N.)

    Measuring patient-centered outcomes is becoming increasingly important in patients with peripheral arterial disease (PAD), both as a means of determining the benefits of treatment and as an aid for disease management. In order to monitor health status in a reliable and sensitive way, the disease-specific measure Peripheral Artery Questionnaire (PAQ) was developed. However, to date, its correlation with traditional clinical indices is unknown. The primary aim of this study was to better establish the clinical validity of the PAQ by examining its association with functional indices related to PAD. Furthermore, we hypothesized that the clinical validity of this disease-specific measure is better as compared with the EuroQol-5-dimensional (EQ-5D), a standardized generic instrument. Data on 711 consecutive PAD patients undergoing surgery were collected from 11 Dutch hospitals in 2004. At 3-year follow-up, questionnaires including the PAQ, EQ-5D, and EuroQol-Visual Analogue Scale (EQ VAS) were completed in 84% of survivors. The PAQ was analyzed according to three domains, as established by a factor analyses in the Dutch population, and the summary score. Baseline clinical indices included the presence and severity of claudication intermittent (CI) and the Lee Cardiac Risk Index. All three PAQ domains (Physical Function, Perceived Disability, and Treatment Satisfaction) were significantly associated with CI symptoms (P values PAQ summary scores as compared with asymptomatic patients (58.6 +/- 27.8 vs 68.6 +/- 27.8, P = PAQ summary score and the subscale scores for Physical Functioning and Perceived Disability demonstrated a clear dose-response relation for walking distance and the Lee Risk Index (P values PAQ proved to be good as the PAQ subscales discriminated well between patients with or without symptomatic PAD and its severity as defined by walking distance. Furthermore, the PAQ subscales were directly proportional to the presence and number of risk factors relevant

    Idiopathic Parkinson's disease (PD) and Alzheimer's disease (AD) are the main neuro-degenerative diseases (NDDs) seen clinically. They share some common clinical symptoms and neuro-pathological findings. The increase of life expectancy in the developed countries will inevitably contribute to enhance the prevalence of these diseases. Behavioral disorders, common in NDDs, will produce major care management challenges. Idiopathic Parkinson's disease corresponds to a histopathological diagnosis, based on the observation of a de-pigmentation and a neuronal loss in the substantia nigra, as well as on the presence of intra-neuronal inclusion bodies. AD is insidious with slowly progressive dementia in which the decline in memory constitutes the main complaint. The diagnosis of definite AD requires the presence of clinical criteria as well as the histopathological confirmation of brain lesions. The two main lesions are the presence of senile plaques and neuro-fibrillary tangles. Positron emission tomography (PET) explores cerebral metabolism and neurotransmitter kinetics in NDDs using principally [{sup 18}F]-deoxyglucose and [{sup 18}F]-dopa. Nigrostriatal dopaminergic function is altered in PD, as evidenced by the low uptake of [{sup 18}F]-dopa in the posterior putamen as compared to anterior putamen and caudate nucleus. In contrast, [{sup 18}F]-dopa uptake is equally depressed in all striatal structures in progressive supra-nuclear palsy. Regional glucose metabolism at rest is preserved in elderly once cerebral atrophy is taken into account. On the contrary, glucose metabolism is globally reduced in AD, with marked decrease in the parietal and temporal regions. PET has proved to be useful to study in vivo neurochemical processes in patients suffering from NDDs. The potential of this approach is still largely unexploited, and depends on new ligand production to establish early diagnosis and treatment follow-up. (author)

    The use of drug-eluting stents (DES) vs bare-metal stents (BMS) in saphenous vein graft (SVG) lesions remains controversial. We conducted a meta-analysis of all randomized clinical trials comparing the outcomes of DES with BMS in SVG percutaneous coronary interventions. A search of PubMed, Embase, the Cochrane Register of Controlled Trials, and Clinicaltrials.gov was performed for all randomized clinical trials. We evaluated the short- and long-term clinical outcomes of the following: all-cause mortality, major adverse cardiovascular events (MACE), definite/probable stent thrombosis, target lesion revascularization (TLR), and target-vessel revascularization (TVR). From a total of 1582 patients in 6 randomized clinical trials, 797 had DES and 785 had BMS. Patients with DES had lower short-term MACE, TLR, and TVR in comparison with BMS (odds ratio [OR]: 0.56, 95% confidence interval [CI]: 0.35-0.91, P = 0.02; OR: 0.43, 95% CI: 0.19-0.99, P = 0.05; and OR: 0.45, 95% CI: 0.22-0.95, P = 0.04, respectively). However, there were no different outcomes for all-cause mortality (P = 0.63) or stent thrombosis (P = 0.21). With long-term follow-up, there were no significant reductions of MACE (P = 0.20), TLR (P = 0.57), TVR (P = 0.07), all-cause mortality (P = 0.29), and stent thrombosis (P = 0.76). The use of DES in SVG lesions was associated with lower short-term MACE, TLR, and TVR in comparison with BMS. However, there were no significant differences with long-term follow-up. © 2018 Wiley Periodicals, Inc.

    Clinical diagnosis of sporadic Creutzfeldt-Jakob disease (sCJD) is currently based on changes occurring in the late disease stages, which limits early-stage detection. Therefore, we investigated the disease course from the vague symptomatic to the terminal phase. We retrospectively reviewed 36 sCJD patient records, classifying the disease progression into 4 stages based on clinical manifestations: vague symptomatic, possible CJD, probable CJD and chronic vegetative state. We analyzed findings from diffusion-weighted imaging (DWI), electroencephalography (EEG) and cerebrospinal fluid (CSF) 14-3-3 protein testing performed at each stage. In stage 1, the most distinctive feature was DWI hyperintensities in the neocortex, even with negative CSF 14-3-3 protein and EEG results. In stage 2, DWI hyperintensities in the limbic cortex were more remarkable. CSF 14-3-3 protein testing yielded positive results in >80% of patients; EEG showed sensitivity in disease stage-dependent differences in clinical symptoms and laboratory test results will facilitate early and accurate diagnosis. © 2016 S.

    Transition from pediatric to adult care is a critical time for patients with congenital heart disease. Lapses in care can lead to poor outcomes, including increased mortality. Formal transition clinics have been implemented to improve success of transferring care from pediatric to adult providers; however, data regarding outcomes remain limited. We sought to evaluate outcomes of transfer within a dedicated transition clinic for young adult patients with congenital heart disease. We performed a retrospective analysis of all 73 patients seen in a dedicated young adult congenital heart disease transition clinic from January 2012 to December 2015 within a single academic institution that delivered pediatric and adult care at separate children's and adult hospitals, respectively. Demographic characteristics including congenital heart disease severity, gender, age, presence of comorbidities, presence of cardiac implantable electronic devices, and type of insurance were correlated to success of transfer. Rate of successful transfer was evaluated, and multivariate analysis was performed to determine which demographic variables were favorably associated with transfer. Thirty-nine percent of patients successfully transferred from pediatric to adult services during the study period. Severe congenital heart disease (OR 4.44, 95% CI 1.25-15.79, P = .02) and presence of a cardiac implantable electronic device (OR 4.93, 95% CI 1.18-20.58, P = .03) correlated with transfer. Trends favoring successful transfer with presence of comorbidities and private insurance were also noted. Despite a dedicated transition clinic, successful transfer rates remained relatively low though comparable to previously published rates. Severity of disease and presence of implantable devices correlated with successful transfer. Other obstacles to transfer remain and require combined efforts from pediatric and adult care systems, insurance carriers, and policy makers to improve transfer outcomes.

    Recent studies showed that a low ratio between the levels of eicosapentaenoic acid and those of arachidonic acid (EPA/AA) is associated with higher incidence of coronary artery disease and poor prognosis of heart failure, arrhythmia, and cardiac sudden death. However, the clinical implications of EPA/AA in adult patients with congenital heart disease remain unclear. We aimed to assess the prognostic value of EPA/AA regarding cardiac events in adult patients with congenital heart disease. We measured the serum levels of eicosapentaenoic acid and arachidonic acid in 130 adult patients (median age, 31 years) stratified into two groups according to their EPA/AA (low, ≤0.22; high, >0.22). We prospectively analyzed the association between EPA/AA and incidence of cardiac events during a mean observation period of 15 months, expressed in terms of hazard ratio (HR) with 95% confidence interval (95% CI). In the subgroup of patients with biventricular circulation (2VC) (n = 76), we analyzed the same clinical endpoints. In our study population, EPA/AA was not associated with the incidence of arrhythmic events (HR, 1.52; 95% CI, 0.82-2.85; p = 0.19), but low EPA/AA was a predictor of heart failure hospitalization (HR, 2.83; 95% CI, 1.35-6.30; p AA of ≤0.25 was associated with a significantly higher risk of arrhythmic events (HR, 2.55; 95% CI, 1.11-6.41; p = 0.03) and heart failure hospitalization (HR, 5.20; 95% CI, 1.78-18.1; p AA represents a useful predictor of cardiac events in adult patients with congenital heart disease.

    Whipple's disease (WD) is a rare systemic disease of infectious etiology which involves the small intestine but can virtually affect any organ. We present here five cases (four males and one female) ranging in age from 20 to 59 years. All patients had intestinal involvement associated or not with clinical manifestations linked to this organ. Vegetation in the tricuspid valve was observed in one patient, suggesting endocarditis caused by Tropheryma whippelii, with disappearance of the echocardiographic alterations after treatment. In one of the male patients the initial clinical manifestation was serologically negative spondylitis, with no diarrhea occurring at any time during follow-up. Ocular involvement associated with intestinal malabsorption and significant weight loss were observed in one case. In the other two cases, diarrhea was the major clinical manifestation. All patients were diagnosed by histological examination of the jejunal mucosa and, when indicated, of extraintestinal tissues by light and electron microscopy. After antibiotic treatment, full remission of symptoms occurred in all cases. A control examination of the intestinal mucosa performed after twelve months of treatment with sulfamethoxazole-trimethoprim revealed the disappearance of T. whippelii in four patients. The remaining patient was lost to follow-up.

    To explore the feasibility of disease-specific clinical pathways when used in primary care. A mixed-method sequential exploratory design was used. First, merging and exploring quality interview data across two cases of collaboration between the specialist care and primary care on the introduction of clinical pathways for four selected chronic diseases. Secondly, using quantitative data covering a population of 214,700 to validate and test hypothesis derived from the qualitative findings. Primary care and specialist care collaborating to manage care coordination. Primary-care representatives expressed that their patients often have complex health and social needs that clinical pathways guidelines seldom consider. The representatives experienced that COPD, heart failure, stroke and hip fracture, frequently seen in hospitals, appear in low numbers in primary care. The quantitative study confirmed the extensive complexity among home healthcare nursing patients and demonstrated that, for each of the four selected diagnoses, a homecare nurse on average is responsible for preparing reception of the patient at home after discharge from hospital, less often than every other year. The feasibility of disease-specific pathways in primary care is limited, both from a clinical and organisational perspective, for patients with complex needs. The low prevalence in primary care of patients with important chronic conditions, needing coordinated care after hospital discharge, constricts transferring tasks from specialist care. Generic clinical pathways are likely to be more feasible and efficient for patients in this setting. Key points Clinical pathways in hospitals apply to single-disease guidelines, while more than 90% of the patients discharged to community health care for follow-up have multimorbidity. Primary care has to manage the health care of the patient holistically, with all his or her complex needs. Patients most frequently admitted to hospitals, i.e. patients with COPD

    The role of fecal microbiota transplant (FMT) in the treatment of pediatric inflammatory bowel disease (IBD) is unknown. The aims of this study were to assess safety, clinical response, and gut microbiome alterations in children with Crohn's disease (CD), ulcerative colitis (UC), or indeterminate colitis (IC). In this open-label, single-center prospective trial, patients with IBD refractory to medical therapy underwent a single FMT by upper and lower endoscopy. Adverse events, clinical response, gut microbiome, and biomarkers were assessed at baseline, 1 week, 1 month, and 6 months following FMT. Twenty-one subjects were analyzed, with a median age of 12 years, of whom 57% and 28% demonstrated clinical response at 1 and 6 months post-FMT, respectively. Two CD patients were in remission at 6 months. Adverse events attributable to FMT were mild to moderate and self-limited. Patients prior to FMT showed decreased species diversity and significant microbiome compositional differences characterized by increased Enterobacteriaceae, Enterococcus, Haemophilus, and Fusobacterium compared with donors and demonstrated increased species diversity at 30 days post-FMT. At 6 months, these changes shifted toward baseline. Clinical responders had a higher relative abundance of Fusobacterium and a lower diversity at baseline, as well as a greater shift toward donor-like microbiome after FMT compared with nonresponders. A single FMT is relatively safe and can result in a short-term response in young patients with active IBD. Responders possessed increased Fusobacterium prior to FMT and demonstrated more significant microbiome changes compared with nonresponders after FMT. Microbiome characteristics may help in predicting response. © 2018 Crohn’s & Colitis Foundation of America. Published by Oxford University Press. All rights reserved.

    Approximately 10% to 20% of patients optimally treated for early Lyme disease develop persistent symptoms of unknown pathophysiology termed posttreatment Lyme disease syndrome (PTLDS). The objective of this study was to investigate associations between PTLDS and immune mediator levels during acute illness and at several time points following treatment. Seventy-six participants with physician-documented erythema migrans and 26 healthy controls with no history of Lyme disease were enrolled. Sixty-four cytokines, chemokines, and inflammatory markers were measured at each visit for a total of 6 visits over 1 year. An operationalized definition of PTLDS incorporating symptoms and functional impact was applied at 6 months and 1 year following treatment completion, and clinical outcome groups were defined as the return-to-health, symptoms-only, and PTLDS groups. Significance analysis of microarrays identified 7 of the 64 immune mediators to be differentially regulated by group. Generalized logit regressions controlling for potential confounders identified posttreatment levels of the T-cell chemokine CCL19 to be independently associated with clinical outcome group. Receiver operating characteristic analysis identified a CCL19 cutoff of >111.67 pg/ml at 1 month following treatment completion to be 82% sensitive and 83% specific for later PTLDS. We speculate that persistently elevated CCL19 levels among participants with PTLDS may reflect ongoing, immune-driven reactions at sites distal to secondary lymphoid tissue. Our findings suggest the relevance of CCL19 both during acute infection and as an immunologic risk factor for PTLDS during the posttreatment phase. Identification of a potential biomarker predictor for PTLDS provides the opportunity to better understand its pathophysiology and to develop early interventions in the context of appropriate and specific clinical information.

    To determine the effect of clinical presentations of neck pain on short-term physical therapy outcomes. Retrospective analysis of pair-matched groups from a clinical cohort. Thirteen outpatient physical therapy clinics in 1 health care system. Patients (N=1069) grouped by common clinical presentations of neck pain: nonspecific neck pain (NSNP) with duration 4 weeks; neck pain with arm pain; neck pain with headache; and neck pain from whiplash. Conservative interventions provided by physical therapists. Neck Disability Index (NDI) and numerical pain rating scale (NPRS) recorded at the initial and last visits. The main outcome of interest was achieving recovery status on the NDI. Changes in NDI and NPRS were compared between clinical presentation groups. Compared with patients presenting with NSNP >4 weeks, patients with NSNP neck pain and arm pain demonstrated an increased odds of achieving recovery status on the NDI (P=.04) compared with patients presenting with NSNP >4 weeks. Treating patients with NSNP within <4 weeks of onset of symptoms may lead to improved clinical outcomes from physical therapy compared with other common clinical presentations.

    Full Text Available The paper analyzes the results of an investigation into the relationship between Behcet's disease (BB and mental disorders. It establishes the importance of an emotional stress factor for developing the clinical symptoms and disease. In its turn, the systemic immune inflammatory disease and its complications become a source of mental disorders. The literature describes different variants of BB, but anxiety-depressive spectrum disorders and moderate cognitive impairments are most common. The presence of depression contributes significantly to lower quality of life in patients with BB.

    Decisions about the dissemination of HIV interventions need to be informed by evidence of their cost-effectiveness in reducing negative health outcomes. Having previously shown the effectiveness of a single-session video-based group intervention (VOICES/VOCES) in reducing incidence of sexually transmitted diseases (STD) among male African American and Latino clients attending an urban STD clinic, this study estimates its cost-effectiveness in terms of disease averted. Cost-effectiveness was calculated using data on effectiveness from a randomized clinical trial of the VOICES/VOCES intervention along with updated data on the costs of intervention from four replication sites. STD incidence and self-reported behavioral data were used to make estimates of reduction in HIV incidence among study participants. The average annual cost to provide the intervention to 10 000 STD clinic clients was estimated to be US$447 005, with a cost per client of US$43.30. This expenditure would result in an average of 27.69 HIV infections averted, with an average savings from averted medical costs of US$5 544 408. The number of quality adjusted life years saved averaged 387.61, with a cost per HIV infection averted of US$21 486. This brief behavioral intervention was found to be feasible and cost-saving when targeted to male STD clinic clients at high risk of contracting and transmitting infections, indicating that this strategy should be considered for inclusion in HIV prevention programming.

    Cushing’s disease is considered a rare condition characterized by the hypersecretion of the adrenocorticotropic hormone (ACTH) due to a pituitary adenoma that ultimately causes endogenous hypercortisolism by stimulating the adrenal glands. The clinical signs suggesting Cushing’s disease, such as obesity, moon face, hirsutism, and facial plethora are already present on presentation. Endogenous hypercortisolism is associated with an increased risk of cardiovascular and metabolic manifestations, as well as respiratory disorders, psychiatric complications, osteoporosis and infections, leading to high rates of morbidity and mortality. It is vital to diagnose Cushing’s disease as early as possible and to implement a treatment plan to lead to a successful prognosis and a low number of complications. The goal of this article was to review the clinical, diagnostic and treatment aspects of Cushing’s disease using the most recent available guidelines. PMID:27974908

    To see the histological outcome of duodenal biopsies done in patients clinically suspected of celiac disease. Study Design: Prospective descriptive study. Place and Duration of Study: Histopathology Department, Army Medical College Rawalpindi, from 1 Jan 2017 to 30 Jun 2017. Material and Methods: One hundred (100) cases were included in the study. Duodenal biopsies done in patients clinically suspected of celiac disease were included in the study. Inadequate biopsies were excluded from the study. All the normal and abnormal histological features were noted to make the diagnosis. Data was entered and analyzed by using SPSS version 17. Results: Duodenal biopsies of 100 patients, done in clinically suspected cases of celiac disease were analyzed histologically. Out of these 100 cases, 46 cases (46%) showed histological features consistent with celiac disease, while 38 cases (38%) revealed chronic non specific duodenitis, 2 cases (2%) were of giardiasis, while 14 biopsies (14%) were unremarkable with no significant pathology. Conclusion: A significant number of cases clinically suspected of celiac disease may not be showing histological features consistent with celiac disease on duodenal biopsies. Due to the changing presentation of disease, as well as the recognition of a number of potential clinical and histopathological mimics, communication between pathologists and gastroenterologists is essential for appropriate interpretation of duodenal biopsy specimens.

    To evaluate the clinical and epidemiological profile of patients with valvular heart disease who arrived decompensated at the emergency department of a university hospital in Brazil. A descriptive analysis of clinical and echocardiographic data of 174 patients with severe valvular disease, who were clinically decompensated and went to the emergency department of a tertiary cardiology hospital, in the State of São Paulo, in 2009. The mean age of participants was 56±17 years and 54% were female. The main cause of valve disease was rheumatic in 60%, followed by 15% of degenerative aortic disease and mitral valve prolapse in 13%. Mitral regurgitation (27.5%) was the most common isolated valve disease, followed by aortic stenosis (23%), aortic regurgitation (13%) and mitral stenosis (11%). In echocardiographic data, the mean left atrial diameter was 48±12mm, 38±12mm for the left ventricular systolic diameter, and 54±12mm for the diastolic diameter; the mean ejection fraction was 56±13%, and the mean pulmonary artery pressure was 53±16mmHg. Approximately half of patients (44%) presented atrial fibrillation, and over one third of them (37%) had already undergone another cardiac surgery. Despite increased comorbidities and age-dependent risk factors commonly described in patients with valvular heart disease, the clinical profile of patients arriving at the emergency department represented a cohort of rheumatic patients in more advanced stages of disease. These patients require priority care in high complexity specialized hospitals.

    In order to extract meaningful information from electronic medical records, such as signs and symptoms, diagnoses, and treatments, it is important to take into account the contextual properties of the identified information: negation, temporality, and experiencer. Most work on automatic identification of these contextual properties has been done on English clinical text. This study presents ContextD, an adaptation of the English ConText algorithm to the Dutch language, and a Dutch clinical corpus. We created a Dutch clinical corpus containing four types of anonymized clinical documents: entries from general practitioners, specialists' letters, radiology reports, and discharge letters. Using a Dutch list of medical terms extracted from the Unified Medical Language System, we identified medical terms in the corpus with exact matching. The identified terms were annotated for negation, temporality, and experiencer properties. To adapt the ConText algorithm, we translated English trigger terms to Dutch and added several general and document specific enhancements, such as negation rules for general practitioners' entries and a regular expression based temporality module. The ContextD algorithm utilized 41 unique triggers to identify the contextual properties in the clinical corpus. For the negation property, the algorithm obtained an F-score from 87% to 93% for the different document types. For the experiencer property, the F-score was 99% to 100%. For the historical and hypothetical values of the temporality property, F-scores ranged from 26% to 54% and from 13% to 44%, respectively. The ContextD showed good performance in identifying negation and experiencer property values across all Dutch clinical document types. Accurate identification of the temporality property proved to be difficult and requires further work. The anonymized and annotated Dutch clinical corpus can serve as a useful resource for further algorithm development.

    Periodontal diseases have several implications for the practice of endodontics. First, advanced periodontitis often has direct implications for the long-term prognosis of the case and requires careful evaluation and coordinated treatment of both the periodontic and endodontic diseases. Second, the potential for functional interactions between odontogenic pathoses and marginal periodontitis requires careful collection of clinical observations and monitoring the outcome of various treatments. In this section, we provide an analysis of recent clinical studies in this area.
