    Treatment of peptic ulcer disease has undergone a radical change due to the discovery of its main cause, the Helicobacter pylori infection. The management of the chronic infection is now the primary aim. Treatment of peptic ulcer essentially consists of eradicating H. pylori. A current problem is the resistance developed by H. pylori to the antibiotics used in eradication regimen. Ulcers that are induced by nonsteroidal antirheumatic (NSAR) agents and acetylsalicylic acid are gaining in importance. Optimized inhibition of acid secretion with proton pump inhibitors has made it possible to both prevent and cure ulcers in the stomach and duodenum caused by NSAR agents.

    Full Text Available Objective To formulate the best treatment plan for Alzheimer's disease patients by evaluating the therapeutic efficacy and side effect of various evidence-based programs. 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

    Background: Clinical attachment level is the most frequently used and acceptable parameter in monitoring periodontal status in diseased individual and denotes patterns of periodontal destruction. Awareness of root morphology and the condition of the periodontal tissues is essential for reliable periodontal pocket probing and for effective debridement of root surfaces. Clinically, it is challenging to observe exact nature of complex periodontal attachment loss. The aim of the present study was to evaluate patterns of periodontal destruction based on vertical and horizontal attachment loss. Materials and Methods: A total of 200 extracted teeth were obtained from chronic periodontitis patients. Prior to extraction, clinical measurements were recorded and after extraction, the teeth were stained with crystal violet. Root length, vertical and horizontal attachment loss were measured using digital caliper. Results: There was a significant difference between clinical attachment level and vertical attachment loss for both maxillary and mandibular teeth. Mean vertical attachment loss varied between 5.17 mm and 9.17 mm. Interproximal surfaces exhibited statistically significant vertical attachment loss in both maxillary and mandibular dentition. Results indicated that vertical attachment loss was more severe with teeth belonging to the anterior sextant whereas the horizontal attachment loss was more pronounced with posterior teeth. Conclusion: Both vertical and horizontal attachment loss were observed in all periodontally involved teeth. There was a difference in clinical measurements and actual periodontal status denoted by postextraction staining. These findings have an impact on determining the prognosis and appropriate treatment plan for patients. PMID:27143828

    Full Text Available Patients with chronic kidney disease (CKD exhibit an increased cancer risk compared to a healthy control population. To be able to estimate the cancer risk of the patients and to assess the impact of interventional therapies thereon, it is of particular interest to measure the patients’ burden of genomic damage. Chromosomal abnormalities, reduced DNA repair, and DNA lesions were found indeed in cells of patients with CKD. Biomarkers for DNA damage measurable in easily accessible cells like peripheral blood lymphocytes are chromosomal aberrations, structural DNA lesions, and oxidatively modified DNA bases. In this review the most common methods quantifying the three parameters mentioned above, the cytokinesis-block micronucleus assay, the comet assay, and the quantification of 8-oxo-7,8-dihydro-2′-deoxyguanosine, are evaluated concerning the feasibility of the analysis and regarding the marker’s potential to predict clinical outcomes.

    Clinical manifestations of venous thromboembolism are often subtle or misleading. Yet it is a potentially fatal condition. Although the symptoms and signs at presentation have a poor sensitivity and specificity when considered singly, the physician can accurately assess a clinical probability based on the history, the risk factors, the physical examination and some simple laboratory exams. This essential step allows us to identify a low risk group of patients which will benefit of a non invasive diagnostic strategy. More recently explicit prediction rules were proposed to offset the lack of standardization of this clinical assessment. These new didactic tools can simplify clinical evaluation. Nevertheless, their comparison to implicit evaluation reveals that they should be complemented by the physician's judgement.

    One hundred and twelve cases of renal diseases were studied by computed tomography (CT) using EMI 5005/12. Of them, 60 were examined by both CT and renal scintigraphy, and comparatively evaluated. The CT units were checked before and after the contrast enhancement. Renal scintigrams were obtained by gamma cameras (PHO/GAMMA HP 6406, PHO/GAMMA LFOV) using 99 M Tc-DMSA. CT was especially useful in diagnosing the renal cysts and the hydronephrosis. Cysts in other organs (liver, spleen and pancreas) were simultaneously ascertained in polycystic diseases. CT was not helpful in diagnosing nephritis and diabetic nephropathy. Floating kidney and horse-shoe kidney were difficult to diagnose with CT. The renal scintigram was the reflection of the renal function, and was relatively more useful than CT in diagnosing horse-shoe kidney, floating kidney and nephritis, while it was not useful for non-functioning kidneys.

    Nonalcoholic fatty liver disease (NAFLD) is a diagnosis of exclusion. Most patients are asymptomatic and diagnosed incidentally. Most patients remain undiagnosed. A high index of suspicion and serologic work-up to rule out alternative causes of liver disease is required. In NALFD, fibrosis correlates with outcomes, including mortality. To diagnose, assess severity, and monitor fibrosis, 2 noninvasive methods can be used. However, noninvasive tests are more helpful at extremes of fibrosis: excluding it or diagnosing advanced fibrosis. Liver biopsy is usually reserved for cases whereby noninvasive tests fail to accurately determine the degree of fibrosis or the diagnosis is unclear.

    Thallium SPECT was performed in patients with significant coronary artery stenosis, 67 cases were after maximal exercise and 74 cases were during coronary vasodilation induced by ATP (adenosine triphosphate) infusion. In patients suspected of angina pectoris, the sensitivity, specificity and predictive accuracy for detection of coronary artery disease (CAD) were 88%, 78% and 82% for exercise SPECT, and 100%, 72% and 84% for ATP SPECT studies, respectively. In patients with old myocardial infarction, these were 73%, 100% and 88% for exercise SPECT and 71%, 100% and 81% for ATP SPECT. These were 75%, 49% and 60% for treadmill exercise test in the patient group including both angina and myocardial infarction. For detection of diseased vessels, the diagnostic accuracy for left anterior descending artery and right coronary artery lesions was almost equal for ATP and exercise SPECT study, but ATP SPECT study was more sensitive than exercise SPECT study in detection of left circumflex artery lesions. ATP as well as exercise SPECT studies occasionally gave false positive results in patients with single-vessel disease. ATP as well as exercise SPECT studies underestimated the severity of multi-vessel disease. In general, the results of ATP SPECT imaging were highly concordant with the results of exercise SPECT imaging. ATP stress thallium SPECT imaging provided a safe and highly accurate diagnostic tool for detection of CAD. (author)

    Identifying patients with obstructive coronary artery disease can be challenging for primary care physicians. Advances in precision medicine may help augment clinical tools and redefine the paradigm for evaluating coronary artery disease in the outpatient setting. A blood-based age/sex/gene expression score (ASGES) incorporating key features of precision medicine has shown clinical validity with a 96% negative predictive value and 89% sensitivity in estimating a symptomatic patient's current likelihood of obstructive coronary artery disease. To better characterize the clinical utility of the ASGES and measure its impact on clinician decision-making, a community-based registry was established. The prospective PRESET Registry (NCT01677156) enrolled stable, nonacute adult patients presenting with typical or atypical symptoms suggestive of obstructive coronary artery disease from 21 US primary care practices from August 2012 to August 2014. Demographics, clinical characteristics, and ASGES results (predefined as low [ASGES ≤15] or elevated [ASGES >15]) were collected, as were referrals to Cardiology or further functional/anatomic cardiac testing after ASGES testing. Patients were followed for 1 year post ASGES testing. Among the 566-patient cohort (median age 56 years), clinicians referred 26/252 (10%) of patients with low scores vs 137/314 (44%) of patients with elevated scores to Cardiology or advanced cardiac testing for further evaluation (unadjusted odds ratio 0.15, P medicine in the delivery of cardiovascular care.

    Receiver operating characteristics (ROC) analysis was performed to evaluate the clinical efficacy of transrectal sonography (US) and computed tomography (CT) for prostatic diseases. One hundred US and CT images of prostatic diseases collected from 10 medical institutions, including 33 cases of prostatic cancer, 29 of benign prostatic hypertrophy, 7 of prostatitis, 2 of prostatic stone and 29 of normal finding, were read by 21 urologists. As the results, US was found to be more useful than CT for both the detection of prostatic diseases and the differentiation between prostatic cancer and benign prostatic hypertrophy. The sensitivity of US for the diagnosis of prostatic cancer was 64.2 % on average of all the urologists. However, the sensitivity was 80.0 % on average of 5 urologists who have read more than 3,000 US images and 59.5 % on average of 16 doctors who have read within 3,000 US images.

    Full Text Available Preterm birth means the birth before thirty seven week of pregnancy that causes a lot of complications for the baby. Variety factors are suggested to be involved in disease. In this study, we decided to evaluate haptoglobin (Hp phenotypes association with clinical features of patients suffered from premature delivery to understand better the possible correlation of genetic and clinical features in this disease. This cross-sectional analytic descriptive study has been carried out in two groups of 120 women, 60 with preterm and 60 with term labor. Patients were selected with previously diagnosed by gynecologist with preterm birth in the labor during the study period. After performing diagnostic tests, the frequency of each haptoglobin phenotype in the two groups was analyzed using the Chi-square test (X2 test and SPSS software. The maximum serum haptoglobin phenotype frequency in patients with Hp2-2, was 43 (71.7% whereas in healthy individuals, 35 (58.3%. No, statistically significant differences between the two groups were found (p=0.310. But based on some patients clinical features such as their history of preterm delivery, previous history of recurrent abortions and history of preterm delivery in their family, significant association was found with Hp2-2 compared with healthy control (p<0.003. This study showed that Hp2-2 phenotypes levels in the case group was higher than in control but the factors influencing the presence or absence of preterm labor is clinically various.

    Spinocerebellar ataxias (SCA) are autosomal dominant neurodegenerative disorders that affect the cerebellum and its connections, and have a marked clinical and genetic variability. Machado-Joseph disease (MJD) or spinocerebellar ataxia type 3 (SCA3)--MJD/SCA3--is the most common SCA worldwide. MJD/SCA3 is characterized classically by progressive ataxia and variable other motor and non-motor symptoms. Sleep disorders are common, and include rapid eye movement (REM) sleep behaviour disorder (RBD), restless legs syndrome (RLS), insomnia, excessive daytime sleepiness, excessive fragmentary myoclonus and sleep apnea. This study aims to focus upon determining the presence or not of non-REM (NREM)-related parasomnias in MJD/SCA 3, using data from polysomnography (PSG) and clinical evaluation. Forty-seven patients with clinical and genetic diagnosis of MJD/SCA3 and 47 control subjects were evaluated clinically and by polysomnography. MJD/SCA3 patients had a higher frequency of arousals from slow wave sleep (P parasomnia complaints (confusional arousal/sleep terrors, P = 0.001; RBD, P parasomnias must be included in the spectrum of sleep disorders in MJD/SCA3 patients.

    Dual-energy computed tomography (DECT) simultaneously acquires images at two X-ray energy levels, at both high- and low-peak voltages (kVp). The material attenuation difference obtained from the two X-ray energies can be processed by software to analyze material decomposition and to create additional image datasets, namely, virtual noncontrast, virtual contrast also known as iodine overlay, and bone/calcium subtraction images. DECT has a vast array of clinical applications in imaging cerebrovascular diseases, which includes: (1) Identification of active extravasation of iodinated contrast in various types of intracranial hemorrhage; (2) differentiation between hemorrhagic transformation and iodine staining in acute ischemic stroke following diagnostic and/or therapeutic catheter angiography; (3) identification of culprit lesions in intra-axial hemorrhage; (4) calcium subtraction from atheromatous plaque for the assessment of plaque morphology and improved quantification of luminal stenosis; (5) bone subtraction to improve the depiction of vascular anatomy with more clarity, especially at the skull base; (6) metal artifact reduction utilizing virtual monoenergetic reconstructions for improved luminal assessment postaneurysm coiling or clipping. We discuss the physical principles of DECT and review the clinical applications of DECT for the evaluation of cerebrovascular diseases. PMID:27512615

    Objectives In inflammatory bowel disease (IBD), characterized by chronic mucosal inflammation, rheumatic abnormalities ranging from arthralgia to spondyloarthritis (SpA) are the most common extraintestinal manifestations. The pathogenesis of IBD-related arthritis is unclear. In this study, we search for clinical and immunological differences between patients with IBD-associated spondyloarthritis and IBD patients without SpA symptoms. Material and methods Patients with an established diagnosis of IBD, suffering from Leśniowski-Crohn disease (L-CD, n = 24) or ulcerative colitis (UC, n = 27), were enrolled in the study. Clinical evaluation of patients, based on medical history, blood tests, physical and radiological examinations, allowed two subgroups of patients to be established. One subgroup comprised patients fulfilling criteria for both IBD and SpA (IBD + SpA, n = 29), while the other included IBD patients with arthralgia only (IBD, n = 22). Serum concentrations of interleukins (IL-6, IL-10, IL-21, IL-22, IL-23) and interferon γ (IFN-γ) were measured by specific enzyme-linked immunosorbent assays (ELISA). Results Patients with IBD + SpA were characterized by shorter disease duration (3 vs. 9 years), higher frequency of HLA-B27 positivity (60.7% vs. 4.5%) and uveitis (20.7% vs. 0%), compared with the IBD subgroup. The serum concentrations of C-reactive protein (CRP) and tested cytokines did not differ between IBD + SpA and IBD patients, or between L-CD and UC groups. However, in the IBD + SpA subgroup there was weak to moderate positive correlation between serum concentrations of CRP and several cytokines (IL-6, IL-21, IFN-γ), and additional moderate positive correlation between serum concentrations of IL-23 and clinical activity of SpA. By contrast, in IBD subgroup a strong inverse correlation between serum concentrations of Interleukin 23 and CRP was found. Conclusions IBD-related spondyloarthritis occurs relatively early, affects mostly HLA-B27

    Full Text Available Chronic cough is a common problem in patients visiting physicians and its prevalence in different populations range from 3 to 40%. Postnasal drip, asthma and gastroesophageal reflux are the known cause of chronic cough. Although diagnosis of asthma is usually made by clinical signs and spirometeric results, methacholine challenge test is a good diagnostic test in patients who show normal physical examination and spirometeric results. In this study, the results of methacholine challenge test in chronic cough patients are investigated. This is a cross sectional study performed on patients suffering from chronic cough (over 8 weeks, who went to Pulmonary Disease Clinic of Imam Khomeini Hospital in 2006. Postnasal drip, gastroesophageal reflux was evaluated and ruled out in all patients. Then they were tested by methacholine inhalation using low to high doses of methacholine. The results of test was defined as 20% fall in FEV1 and its relationship with age, sex, history of allergic disease, family history of asthma and smoking status was investigated. 81 patients (36 female and 45 male entered this study who had mean age of 32.5 ± 13.06 years. 81.5% of patients had never smoked or closed contact with smokers, 6.2% were passive smokers, 8.6% were smokers and 3.7% had quit smoking. 37% had suffered from chronic cough less than 6 months, 11% for 6-11 months and 52% for more than 12 months. In 26% of patients, family history of asthma was present and 34.5% had a history of one type of allergy. In 29.5% the results of methacholine challenge test was positive, among them 45.8% showed an intense response and 54.2% a moderate response. The test results and its intensity had no statistically significant relationship with age, sex, smoking status, the duration of cough and family history of asthma, but the relationship between methacholine challenge test and the history of allergic disease was significant. Methacholine challenge test can be used as a

    Exercise electrocardiography is an established mode of evaluation for patients with suspected coronary artery disease. It also provides prognostic information and guides therapeutic management in patients with established disease. However, some patients are unable to exercise because of orthopedic problems, neurologic diseases, peripheral vascular disease, or deconditioning. In the past, these patients have been referred for angiography to help assess their disease. Recently, however, new techniques to assess myocardial perfusion and/or function, including stress echocardiography, have been used in the noninvasive assessment of coronary artery disease in this group of patients. Echocardiography has been used in combination with different drugs, including dobutamine, dipyridamole, and adenosine. Dobutamine is probably the single most studied drug for stress echocardiography. Dobutamine stress echocardiography is a safe, feasible, and valuable technique for evaluating coronary artery disease.

    Early diagnosis of Alzheimer's disease (AD) based on clinical criteria alone may be problematic, while current and future treatments should be administered earlier in order to be more effective. Thus, various disease biomarkers could be used for early detection of AD. We evaluated brain perfusion with 99mTc-HMPAO single photon emission computed tomography (SPECT) and Brodmann areas (BAs) mapping in mild AD using an automated software (NeuroGam) for the semi-quantitative evaluation of perfusion in BAs and the comparison with the software's normal database. We studied 34 consecutive patients with mild AD: 9 men, 25 women, mean age 70.9 ± 8.1 years, mean Mini-Mental State Examination 22.6 ± 2.5. BAs 25L, 25R, 38L, 38R, 28L, 28R, 36L, and 36R had the lower mean perfusion values, while BAs 31L, 31R, 19R, 18L, 18R, 17L, and 17R had the higher mean values. Compared with healthy subjects of the same age, perfusion values in BAs 25L, 25R, 28R, 28L, 36L, and 36R had the greatest deviations from the healthy sample, while the lowest deviations were found in BAs 32L, 32R, 19R, 24L, 17L, 17R, 18L, and 18R. A percentage of ≥94% of patients had perfusion values more than -2SDs below the mean of healthy subjects in BAs 38R, 38L, 36L, 36R, 23L, 23R, 22L, 44L, 28L, 28R, 25L, and 25R. The corresponding proportion was less than 38% for BAs 11L, 19R, 32L, 32R, 18L, 18R, 24L, and 17R. In conclusion, brain SPECT studies with automated perfusion mapping could be useful as an ancillary tool in daily practice, revealing perfusion impairments in early AD.

    To evaluate the image quality, we performed intravenous digital subtraction angiography for various chest diseases in 62 elderly subjects. In large vessel diseases in the chest, adequate imaging was possible in most cases, especially in the main, right and left pulmonary artery and the aorta. However, second order (subsegmental) and more distal order branches were sometimes judged unsatisfactory because of poor image quality. Five cases were evaluated as inadequate because of motion, i.e. respiratory or cardiac movement. The pulmonary circulating time was measured by the time density curve of the pulmonary artery and vein by digital subtraction angiography, and converse correlation between pulmonary circulating time and cardiac index was obtained. Thus it was possible to evaluate the pulmonary circulating dynamics. As mentioned above, intravenous digital subtraction angiography was a useful and safe method for chest diseases, especially in evaluation of large vessels in the elderly.

    Full Text Available Experimental treatments for Ebola virus disease (EVD might reduce EVD mortality. There is uncertainty about the ability of different clinical trial designs to identify effective treatments, and about the feasibility of implementing individually randomised controlled trials during an Ebola epidemic.A treatment evaluation programme for use in EVD was devised using a multi-stage approach (MSA with two or three stages, including both non-randomised and randomised elements. The probabilities of rightly or wrongly recommending the experimental treatment, the required sample size, and the consequences for epidemic outcomes over 100 d under two epidemic scenarios were compared for the MSA, a sequential randomised controlled trial (SRCT with up to 20 interim analyses, and, as a reference case, a conventional randomised controlled trial (RCT without interim analyses. Assuming 50% 14-d survival in the population treated with the current standard of supportive care, all designs had similar probabilities of identifying effective treatments correctly, while the MSA was less likely to recommend treatments that were ineffective. The MSA led to a smaller number of cases receiving ineffective treatments and faster roll-out of highly effective treatments. For less effective treatments, the MSA had a high probability of including an RCT component, leading to a somewhat longer time to roll-out or rejection. Assuming 100 new EVD cases per day, the MSA led to between 6% and 15% greater reductions in epidemic mortality over the first 100 d for highly effective treatments compared to the SRCT. Both the MSA and SRCT led to substantially fewer deaths than a conventional RCT if the tested interventions were either highly effective or harmful. In the proposed MSA, the major threat to the validity of the results of the non-randomised components is that referral patterns, standard of care, or the virus itself may change during the study period in ways that affect mortality

    Background Tremendous advances have occurred in therapies for peripheral vascular disease (PVD); however, until recently it has not been possible to examine the entire clinical trial portfolio of studies for treatment of PVD (both arterial and venous disease). Methods and Results We examined interventional trials registered in ClinicalTrials.gov from October 2007 through September 2010 (n=40,970) and identified 676 (1.7%) PVD trials (n=493 arterial only, n=170 venous only, n=13 both arterial and venous). Most arterial studies investigated lower extremity peripheral artery disease and acute stroke (35% and 24%, respectively), while most venous studies examined deep vein thrombosis/pulmonary embolus prevention (42%) or venous ulceration (25%). A placebo-controlled trial design was used in 27% of the PVD trials, and 4% of the PVD trials excluded patients aged >65 years. Enrollment in at least 1 US site decreased from 51% in 2007 to 41% of trials in 2010. Compared with non-cardiology disciplines, PVD trials were more likely to be double-blinded, investigate use of devices and procedures, and have industry sponsorship and assumed funding source, and less likely to investigate drug and behavioral therapies. Geographic access to PVD clinical trials within the United States is limited to primarily large metropolitan areas. Conclusions PVD studies represent a small group of trials registered in ClinicalTrials.gov, despite the high prevalence of vascular disease in the general population. This low number, compounded by the decreasing number of PVD trials in the United States, is concerning and may limit the ability to inform current clinical practice of patients with PVD.

     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.

    Full Text Available Chagas disease is one of the most important endemic parasitic diseases in Latin America. In its chronic phase, progression to cardiomyopathy has high morbidity and mortality. The persistence of a normal electrocardiogram (ECG provides a similar prognosis to that of a non-diseased population. Benznidazole (BNZ is the only drug with trypanocidal action available in Brazil.A group of 310 patients with chronic Chagas disease who had normal ECGs at the first medical visit performed before 2002 were included. There were 263 patients treated with BNZ and 47 untreated. The follow-up period was 19.59 years. Univariate analyses showed that those treated were younger and predominantly male. As many as 79.08% of those treated and 46.81% of those untreated continued with normal electrocardiograms (p <0.0001. The occurrence of electrocardiographic abnormalities and relevant clinical events (heart failure, stroke, total mortality, and cardiovascular death was less prevalent in treated patients (p <0.001, p: 0.022, p: 0.047 respectively. In multivariate analyses, the parasiticide treatment was an independent variable for persistence of a normal ECG pattern, which was an independent variable in the prevention of significant clinical events. The immunofluorescence titers decreased with the parasitological treatment. However, the small number of tests in untreated patients did not allow the correlation of the decrease of these titers with electrocardiographic alterations.These data suggest that treatment with benznidazole prevents the occurrence of electrocardiographic alterations. On the other hand, patients who develop ECG abnormalities present with more significant clinical events.

    There is growing recognition and understanding of the entities that cause interstitial lung disease (ILD) in infants. These entities are distinct from those that cause ILD in older children and adults. A multidisciplinary panel was convened to develop evidence-based guidelines on the classification, diagnosis, and management of ILD in children, focusing on neonates and infants under 2 years of age. Recommendations were formulated using a systematic approach. Outcomes considered important included the accuracy of the diagnostic evaluation, complications of delayed or incorrect diagnosis, psychosocial complications affecting the patient's or family's quality of life, and death. No controlled clinical trials were identified. Therefore, observational evidence and clinical experience informed judgments. These guidelines: (1) describe the clinical characteristics of neonates and infants (<2 yr of age) with diffuse lung disease (DLD); (2) list the common causes of DLD that should be eliminated during the evaluation of neonates and infants with DLD; (3) recommend methods for further clinical investigation of the remaining infants, who are regarded as having "childhood ILD syndrome"; (4) describe a new pathologic classification scheme of DLD in infants; (5) outline supportive and continuing care; and (6) suggest areas for future research. After common causes of DLD are excluded, neonates and infants with childhood ILD syndrome should be evaluated by a knowledgeable subspecialist. The evaluation may include echocardiography, controlled ventilation high-resolution computed tomography, infant pulmonary function testing, bronchoscopy with bronchoalveolar lavage, genetic testing, and/or lung biopsy. Preventive care, family education, and support are essential.

  9. A healthier approach to clinical trials evaluating resveratrol for primary prevention of age‐related diseases in healthy populations.

    2013-07-01

    In recent years, the wealth of basic science research supporting resveratrol's potential to treat, delay, and even prevent age-related chronic diseases has led to a number of human clinical trials. While such translational research has yielded promising results in clinical populations, recently published conflicting results from studies evaluating resveratrol's potential for primary prevention of chronic disease in healthy / asymptomatic individuals have generated considerable controversy and do not initially appear consistent with findings from animal models. We argue that trials targeting healthy humans are often fundamentally flawed owing to inappropriate use of paradigms only applicable to populations with overt clinical disease and the consequent misleading (typically negative) results can severely retard advancement of drug development. To appropriately perform translational research centered on resveratrol as a primary prevention agent in non-clinical populations, it is critical to utilize study designs which can provide adequate information on clinically relevant outcome measures, avoid paradigms and assumptions from interventions which are specific to clinical populations, and maintain realistic expectations compared to interventions which provide the theoretical maximal response (e.g., caloric restriction and aerobic exercise training).

    Legionnaires' disease is a systemic infectious disease primarily involving the lungs, with multisystemic extrapulmonary manifestations. Any species of Legionella may cause legionnaires' disease in normal and compromised hosts. The clinical diagnosis of legionnaires' disease may be made on the basis of associated extrapulmonary clinical and laboratory findings. Although no single finding in legionnaires' disease is pathognomonic, the association of key extrapulmonary constitutes a typical pattern that is diagnostically characteristic. The syndromic approach based on a weighted point evaluation system described in the article gives physicians a system to arrive at a rapid presumptive clinical diagnosis of legionnaires' disease. Definitive diagnosis of legionnaires' disease is by direct fluorescent antibody testing of respiratory specimens, serological methods, Legionella urinary antigenuria, or culture.

    To evaluate the presence, size and location of enlarged mediastinal lymph nodes (LNs) in patients with valvular heart disease (VHD) using computed tomography scans in correlation with ejection fraction (EF). We retrospectively evaluated 30 patients with VHD, without pre-existing diseases that could cause lymphadenopathy (LAP). The presence, size, and location of LNs greater than 1 cm in short axis diameter were evaluated. The location of mediastinal LNs was recorded according to the International Association for the Study of Lung Cancer. Furthermore, we evaluated the presence of pulmonary edema, pleural effusion, and other thoracic abnormalities and evaluated EF of the heart on transthoracic echocardiography. Sixteen patients (53%) had at least 1 enlarged mediastinal LN. The most frequent locations were lower paratracheal (4R, n = 8/4L, n = 6), subcarinal (7, n = 5) and right upper paratracheal (2R, n = 4) regions. The frequency of mediastinal LAP was higher in patients with aortic regurgitation (2 of 2, 100%) followed by mitral regurgitation (8 of 11, 73%); it was also high in patients with pulmonary edema (80%), pleural effusion (81%), or both (77%), as compared to patients without pulmonary edema or pleural effusion (17%) (p = 0.001). Ten of 30 patients showed an abnormal EF of < 55%; among them, 8 had mediastinal LAP. However, the relationship between EF and LAP was not statistically significant (p = 0.058). Mediastinal LN enlargement is common in patients with VHD, especially in cases of pulmonary edema and pleural effusion. Enlarged mediastinal LNs were frequently observed with abnormal EF, however, the relationship between EF and mediastinal LAP was not statistically significant.

    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.

    2015-01-01

    The pathogenesis of inflammatory bowel disease (IBD) is multifactorial with data suggesting the role of a disturbed interaction between the gut and the intestinal microbiota. A defective mucosal barrier may result in increased intestinal permeability which promotes the exposition to luminal content and triggers an immunological response that promotes intestinal inflammation. IBD patients display several defects in the many specialized components of mucosal barrier, from the mucus layer composition to the adhesion molecules that regulate paracellular permeability. These alterations may represent a primary dysfunction in Crohn's disease, but they may also perpetuate chronic mucosal inflammation in ulcerative colitis. In clinical practice, several studies have documented that changes in intestinal permeability can predict IBD course. Functional tests, such as the sugar absorption tests or the novel imaging technique using confocal laser endomicroscopy, allow an in vivo assessment of gut barrier integrity. Antitumor necrosis factor-α (TNF-α) therapy reduces mucosal inflammation and restores intestinal permeability in IBD patients. Butyrate, zinc, and some probiotics also ameliorate mucosal barrier dysfunction but their use is still limited and further studies are needed before considering permeability manipulation as a therapeutic target in IBD.

    To correlate currently available quantitative CT measurements for airway disease with physiological indices and the body-mass index, airflow obstruction, dyspnea, and exercise capacity (BODE) index in patients with chronic obstructive pulmonary disease (COPD). This study was approved by our institutional review board (IRB number 2778). Written informed consent was obtained from all subjects. The subjects included 188 current and former cigarette smokers from the COPDGene cohort who underwent inspiratory and expiratory CT and also had physiological measurements for the evaluation of airflow limitation, including FEF25-75%, airway resistance (Raw), and specific airway conductance (sGaw). The BODE index was used as the index of clinical symptoms. Quantitative CT measures included % low attenuation areas [% voxels≤950 Hounsfield unit (HU) on inspiratory CT, %LAA-950ins], percent gas trapping (% voxels≤-856HU on expiratory CT, %LAA -856exp), relative inspiratory to expiratory volume change of voxels with attenuation values from -856 to -950HU [Relative Volume Change (RVC)-856 to -950], expiratory to inspiratory ratio of mean lung density (E/I-ratio MLD), Pi10, and airway wall thickness (WT), luminal diameter (LD) and airway wall area percent (WA%) in the segmental, subsegmental and subsubsegmental bronchi on inspiratory CT. Correlation coefficients were calculated between the QCT measurements and physiological measurements in all subjects and in the subjects with mild emphysema (%LAA-950ins Quantitative CT measurements had significant correlations with physiological indices. Among them, E/I-ratio MLD had the strongest correlations with FEF25-75% (r=-0.648, Quantitative CT measurements of gas trapping such as E/I-ratio MLD, correlate better with physiological indices for airway disease than those of airway such as WA% or LD.

    Myocardial sympathetic nerve function can be evaluated by {sup 123}I-metaiodobenzylguanidine (MIBG) scintigraphy. Congestive heart failure is closely related to myocardial sympathetic nerve function. This study evaluated the severity of congestive heart failure in 30 patients with valvular heart disease [aortic regurgitation (AR): n=20, mean age=70{+-}13 years; mitral regurgitation (MR): n=10, mean age=61{+-}18 years], who had chronic heart failure by MIBG myocardial scintigraphy. Single photon emission computed tomography (SPECT) and anterior planar myocardial images were obtained 15 minutes (initial images) and 4 hours (delayed images) after injection of MIBG (111 MBq). Defect score was determined by the delayed SPECT images visually as a semi-quantitative index. Myocardial MIBG uptake was quantified by the heart to upper mediastinum uptake ratio on the delayed anterior planar images (H/M) and mean cardiac MIBG washout rate during 4 hours was calculated from the bull`s eye display data (clearance). These indices were compared with the NYHA class and echocardiographic findings of the patients. MIBG regional defect in the delayed image was most frequently seen in the inferoposterior wall, and defect score and clearance were significantly higher and the H/M ratio was significantly lower in NYHA class III patients than in class II patients. In patients with AR, clearance significantly correlated with left ventricular end-systolic dimension. In patients with MR, both the H/M ratio and clearance significantly correlated with left atrial dimension. Defect score, H/M, and clearance were closely related to the severity of AR and MR. These results indicate that MIBG scan can be used to assess the severity of valvular heart disease. (author).

    The accurate microbiological diagnosis of diarrhoea involves numerous laboratory tests and, often, the pathogen is not identified in time to guide clinical management. With next-generation sequencing (NGS) becoming cheaper, it has huge potential in routine diagnostics. The aim of this study was to evaluate the potential of NGS-based diagnostics through direct sequencing of faecal samples. Fifty-eight clinical faecal samples were obtained from patients with diarrhoea as part of the routine diagnostics at Hvidovre University Hospital, Denmark. Ten samples from healthy individuals were also included. DNA was extracted from faecal samples and sequenced on the Illumina MiSeq system. Species distribution was determined with MGmapper and NGS-based diagnostic prediction was performed based on the relative abundance of pathogenic bacteria and Giardia and detection of pathogen-specific virulence genes. NGS-based diagnostic results were compared to conventional findings for 55 of the diarrhoeal samples; 38 conventionally positive for bacterial pathogens, two positive for Giardia, four positive for virus and 11 conventionally negative. The NGS-based approach enabled detection of the same bacterial pathogens as the classical approach in 34 of the 38 conventionally positive bacterial samples and predicted the responsible pathogens in five of the 11 conventionally negative samples. Overall, the NGS-based approach enabled pathogen detection comparable to conventional diagnostics and the approach has potential to be extended for the detection of all pathogens. At present, however, this approach is too expensive and time-consuming for routine diagnostics.

    Full Text Available Abstract Background Epidemiologic studies of periodontal infection as a risk factor for cardiovascular disease often use clinical periodontal measures as a surrogate for the underlying bacterial exposure of interest. There are currently no methodological studies evaluating which clinical periodontal measures best reflect the levels of subgingival bacterial colonization in population-based settings. We investigated the characteristics of clinical periodontal definitions that were most representative of exposure to bacterial species that are believed to be either markers, or themselves etiologic, of periodontal disease. Methods 706 men and women aged ≥ 55 years, residing in northern Manhattan were enrolled. Using DNA-DNA checkerboard hybridization in subgingival biofilms, standardized values for Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia were averaged within mouth and summed to define "bacterial burden". Correlations of bacterial burden with clinical periodontal constructs defined by the severity and extent of attachment loss (AL, pocket depth (PD and bleeding on probing (BOP were assessed. Results Clinical periodontal constructs demonstrating the highest correlations with bacterial burden were: i percent of sites with BOP (r = 0.62; ii percent of sites with PD ≥ 3 mm (r = 0.61; and iii number of sites with BOP (r = 0.59. Increasing PD or AL severity thresholds consistently attenuated correlations, i.e., the correlation of bacterial burden with the percent of sites with PD ≥ 8 mm was only r = 0.16. Conclusions Clinical exposure definitions of periodontal disease should incorporate relatively shallow pockets to best reflect whole mouth exposure to bacterial burden.

    Full Text Available Introduction. The exacerbation of chronic obstructive pulmonary disease is most often induced by an infection of bacterial origin in over 50% of the cases (or mixed bacterial and viral infection. This study was aimed at evaluating clinical effects of antibiotics co-amoxiclav. Amoxiicillin with clavulanic acid in the treatment of patients with severe chronic obstructive pulmonary disease exacerbation. Material and Methods. The investigation included 38 patients with severe chronic obstructive pulmonary disease exacerbation hospitalized at the Institute for Pulmonary Diseases of Vojvodina, Sremska Kamenica. The patients were randomly selected for the antibiotic treatment with Amoxiclav twice a day in 12 hour intervals. The clinical effects of the applied treatment were evaluated by analyzing certain laboratory findings, microbiological sputum findings and improvement of subjective symptoms. Results. Of the examined subjects, 65% were males and 35% were females, their mean age being 66.4+8.86, and who were mostly smokers (73%. After the completion of applied antibiotic treatment, a significant reduction and normalization of all inflammation markers were recorded, as well as a significant improvement of the patients’ subjective symptoms. The positive microbiological sputum findings (Haemophilus influenzae, Pseudomonas aeruginosa and Streptococcus pneumoniae were recorded in 13.58% of the patients. The bacterial agent was eradicated on the third day of the applied treatment. The mean length of the treatment was 7.07+0.91 days, with no undesirable treatment side effects observed. Conclusion. The antibiotic therapy is justifiable as the initial treatment regimen of severe chronic obstructive pulmonary disease exacerbation and amoxicillin with clavulanic acid is reported as the first-line antibiotic drug in most pharmacotherapy guidelines.

It has also been called acid maltase deficiency and glycogen storage disease type II. There is a broad clinical presentation: the most severe form that presents in the first few months of life with cardiomyopathy and generalized muscle weakness that rapidly progresses to death from cardio-respiratory failure in the first year of life (infant-onset Pompe disease. A more slowly progressive disease, with little or no cardiac involvement, presents with proximal myopathy and/or pulmonary insufficiency, from the second year of life to late adulthood (late-onset Pompe disease. The recent development and introduction of enzyme replacement therapy with intravenous infusion of recombinant human acid alpha-glucosidase have made a major improvement in the morbidity and mortality of this disease. New therapies are also in development. With the availability of treatment, diagnostic methods have also improved, allowing for earlier recognition and potential early therapeutic intervention. The advent of newborn screening for Pompe disease may identify patients who can be treated before significant irreversible disease has occurred.

    Full Text Available Abstract Background Osteoporosis affects over 200 million people worldwide at a high cost to healthcare systems. Although guidelines are available, patients are not receiving appropriate diagnostic testing or treatment. Findings from a systematic review of osteoporosis interventions and a series of focus groups were used to develop a functional multifaceted tool that can support clinical decision-making in osteoporosis disease management at the point of care. The objective of our study was to assess how well the prototype met functional goals and usability needs. Methods We conducted a usability study for each component of the tool--the Best Practice Recommendation Prompt (BestPROMPT, the Risk Assessment Questionnaire (RAQ, and the Customised Osteoporosis Education (COPE sheet--using the framework described by Kushniruk and Patel. All studies consisted of one-on-one sessions with a moderator using a standardised worksheet. Sessions were audio- and video-taped and transcribed verbatim. Data analysis consisted of a combination of qualitative and quantitative analyses. Results In study 1, physicians liked that the BestPROMPT can provide customised recommendations based on risk factors identified from the RAQ. Barriers included lack of time to use the tool, the need to alter clinic workflow to enable point-of-care use, and that the tool may disrupt the real reason for the visit. In study 2, patients completed the RAQ in a mean of 6 minutes, 35 seconds. Of the 42 critical incidents, 60% were navigational and most occurred when the first nine participants were using the stylus pen; no critical incidents were observed with the last six participants that used the touch screen. Patients thought that the RAQ questions were easy to read and understand, but they found it difficult to initiate the questionnaire. Suggestions for improvement included improving aspects of the interface and navigation. The results of study 3 showed that most patients were able

    The aim of this study was to evaluate the oral manifestations of celiac disease (CD), the chemical composition of dental enamel, and the occurrence of CD in children with dental enamel defects (DEDs). In the study, 52 children with CD and 52 controls were examined for DEDs, recurrent aphthous stomatitis (RAS), dental caries experience, and salivary parameters. In addition, 10 exfoliated primary enamel molars from each group were analyzed by energy dispersive x-ray spectroscopy and Fourier transform infrared spectroscopy. Fifty children with DEDs were submitted to CD diagnosis. Among the children with CD, a higher prevalence of DEDs (P = .00001) and RAS (P = .0052), lower caries experience (P = .0024), and reduction of salivary flow (P = .0060) were observed. Dental enamel from the children with CD demonstrated a lower calcium-to-phosphorus ratio (P = .0136), but no difference in the carbonate-to-phosphate ratio (P = .5862) was observed. In the multivariate analysis, CD was a protective factor for caries (OR = 0.74) and a risk factor for RAS (OR3.23). The children with CD presented with more RAS, DEDs, reduction of salivary flow, and chemical alterations in the enamel. Copyright © 2015 Elsevier Inc. All rights reserved.

    The extensive use of the Unified Parkinson's Disease Rating Scale (UPDRS) has revealed low interrater reliability in some items and redundancy in others. In view of these shortcomings, we have structured a new scale that includes a zero-to three-point scale for each item in the evaluation of PD. The mental axis includes memory, thought disorders, and depression. Activities of daily living (ADL) includes eight items: speech, eating, feeding, dressing, hygiene, handwriting, walking, and turning in bed. The motor examination includes eight items: speech, tremor, rest and posture, rigidity, finger tapping, arising from chair, gait, and postural stability. Complications of therapy were also included: dyskinesias, dystonia, motor fluctuations, and freezing episodes, collected by history. In addition, a global scoring for motor fluctuations that should complement the Hoehn and Yahr Scale was incorporated. In this report, we present a statistical analysis of the ADL, motor evaluation, and complications of therapy sections. Concerning the interrater reliability mean, Kendall's W values were >0.9 for most of the items in the Short Parkinson's Evaluation Scale (SPES). Kendall's W <0.8 (motor evaluation) was found for two items of the SPES and nine items of the UPDRS. The mean interrater reliability for both scales across all seven centers (seven Kendall's W for seven centers) (Mann-Whitney test) showed no statistical differences between the scales. Spearman's correlations between items of both scales were significant. Factor analysis of the SPES and UPDRS data revealed a four-factor solution that explained approximately 60% of the data. All participating centers found the SPES easier to apply and quicker to complete, when compared with the UPDRS. The results obtained strongly favor the introduction of SPES for clinical practice.

    Full Text Available Abstract Background Several investigations are currently available to establish the diagnosis of coronary heart disease (CHD. Of these, cardiovascular magnetic resonance (CMR offers the greatest information from a single test, allowing the assessment of myocardial function, perfusion, viability and coronary artery anatomy. However, data from large scale studies that prospectively evaluate the diagnostic accuracy of multi-parametric CMR for the detection of CHD in unselected populations are lacking, and there are few data on the performance of CMR compared with current diagnostic tests, its prognostic value and cost-effectiveness. Methods/design This is a prospective diagnostic accuracy cohort study of 750 patients referred to a cardiologist with suspected CHD. Exercise tolerance testing (ETT will be preformed if patients are physically able. Recruited patients will then undergo CMR and single photon emission tomography (SPECT followed in all patients by invasive X-ray coronary angiography. The order of the CMR and SPECT tests will be randomised. The CMR study will comprise rest and adenosine stress perfusion, cine imaging, late gadolinium enhancement and whole-heart MR coronary angiography. SPECT will use a gated stress/rest protocol. The primary objective of the study is to determine the diagnostic accuracy of CMR in detecting significant coronary stenosis, as defined by X-ray coronary angiography. Secondary objectives include an assessment of the prognostic value of CMR imaging, a comparison of its diagnostic accuracy against SPECT and ETT, and an assessment of cost-effectiveness. Discussion The CE-MARC study is a prospective, diagnostic accuracy cohort study of 750 patients assessing the performance of a multi-parametric CMR study in detecting CHD using invasive X-ray coronary angiography as the reference standard and comparing it with ETT and SPECT.

    The aim of this study was to determine the presence of periodontal disease among patients with rheumatoid arthritis (RA) in comparison with a control group. The study included 44 patients diagnosed with RA according to American Rheumatism Association (ARA) criteria, who were attending the Morales Meseguer Hospital Rheumatology Service (Murcia, Spain), and 41 control subjects. Patients younger than 18 years or patients suffering systemic diseases that could affect the immune system were excluded. Age, sex, smoking habits, alcohol consumption, and body mass index were registered. Each patient underwent a full periodontal examination. Bleeding on probing was significantly greater in the RA group (0.9 ± 0.36) than the control (P periodontal disease (95% confidence interval, 0.05-0.37). Patients with RA suffered a higher risk of periodontal disease and for this reason these patients must be instructed to intensify their oral hygiene regimes.

    The first-ever application of high-frequency ultrasound combined with multiphoton tomography (MPT) and dermoscopy in a clinical trial is reported. 47 patients with different dermatoses such as benign and malign skin cancers, connective tissue diseases, inflammatory skin diseases, and autoimmune bullous skin diseases have been investigated with (i) state-of-the-art and highly sophisticated ultrasound systems for dermatology, (ii) the femtosecond laser multiphoton tomograph and (iii) dermoscopes. Dermoscopy provides two-dimensional color images of the skin surface with a magnification up to 70 x. Depending on the ultrasonic frequencies from 7.5 MHz to 100 MHz, the signal depth varies from about 1 mm to 80 mm. Vertical ultrasound wide-field images provide fast information on depth and volume of the lesion. The 100 MHz ultrasound allows imaging with resolutions down to 16 μm (axial) and 32 μm (lateral). Multiphoton tomography provides 0.36 x 0.36 x 0.001 mm³ horizontal optical sections of a particular region of interest with submicron resolution down to 200 μm tissue depth. The autofluorescence of mitochondrial coenzymes, keratin, melanin, and elastin as well as the network of collagen structures can be imaged. The combination of ultrasound and MPT opens novel synergistic possibilities in diagnostics of skin diseases with a special focus on the early detection of skin cancer as well as the evaluation of treatments.

    Cell-based therapies, as potential approach to cure peripheral artery disease (PAD), have been clinically investigated after promising results in preclinical models. The so far published studies are very heterogeneous, as different cell sources, cell types, amounts of administered cells and delivering strategies have been used. Overall, cell therapies for PAD bring about a general improvement of patient's clinical condition, even though conclusions cannot be established due to the small size and non-randomized design of these trials. In this context, non-invasive imaging techniques, aimed to monitor angiogenesis and neovascularization after cell therapy, will help the follow-up of clinical studies. However, still much work is needed to establish advanced imaging procedure to overcome the limitation of the current techniques and to accumulate more data in large populations of patients. Here, we report the main imaging techniques employed to evaluate the outcome of the different cell-based therapies in PAD. Moreover, we focus on both published and ongoing clinical trials utilizing cell therapy in PAD.

    In clinically severe cervical spondylosis, imaging plays a vital role in surgical decisions. A prime factor is acquired canal stenosis with cord compression. To validate this concept, the clinical and imaging features of 20 patients with spondylitic myelopathy and 24 with radiculopathy were retrospectively reviewed. All had computed tomographic myelography (CTM) as part of their clinical work-up. The patients` clinical severity was graded as mild, moderate and severe; the age, length of illness and a history of eventual surgery or otherwise were recorded. At the level of maximum compression the following parameters were obtained from the axial CTM images: surface area and ratio of the anteroposterior to the transverse diameter of the cord; subarachnoid space and vertebral canal areas. Data were statistically analysed. A significant association exists between surgery and increasing severity of symptoms (P=0.04), and advancing age (P=0.01). These associations hold true for myelopathy and radiculopathy. A strong association is present between surgery and the surface area of the cord (P=0.01), being applicable to myelopathy only. The other parameters show no association with surgical decisions. It is concluded that with myelopathy a narrow cord area at the level of maximum compression, and moderate-severe functional impairment are indicators for surgical intervention.

    Osteoporosis affects over 200 million people worldwide at a high cost to healthcare systems. Although guidelines on assessing and managing osteoporosis are available, many patients are not receiving appropriate diagnostic testing or treatment. Findings from a systematic review of osteoporosis interventions, a series of mixed-methods studies, and advice from experts in osteoporosis and human-factors engineering were used collectively to develop a multicomponent tool (targeted to family physicians and patients at risk for osteoporosis) that may support clinical decision making in osteoporosis disease management at the point of care. A three-phased approach will be used to evaluate the osteoporosis tool. In phase 1, the tool will be implemented in three family practices. It will involve ensuring optimal functioning of the tool while minimizing disruption to usual practice. In phase 2, the tool will be pilot tested in a quasi-experimental interrupted time series (ITS) design to determine if it can improve osteoporosis disease management at the point of care. Phase 3 will involve conducting a qualitative postintervention follow-up study to better understand participants' experiences and perceived utility of the tool and readiness to adopt the tool at the point of care. The osteoporosis tool has the potential to make several contributions to the development and evaluation of complex, chronic disease interventions, such as the inclusion of an implementation strategy prior to conducting an evaluation study. Anticipated benefits of the tool may be to increase awareness for patients about osteoporosis and its associated risks and provide an opportunity to discuss a management plan with their physician, which may all facilitate patient self-management.

    To evaluate the detection of pituitary lesions at 7.0 T compared to 1.5 T MRI in 16 patients with clinically and biochemically proven Cushing's disease. In seven patients, no lesion was detected on the initial 1.5 T MRI, and in nine patients it was uncertain whether there was a lesion. Firstly, two readers assessed both 1.5 T and 7.0 T MRI examinations unpaired in a random order for the presence of lesions. Consensus reading with a third neuroradiologist was used to define final lesions in all MRIs. Secondly, surgical outcome was evaluated. A comparison was made between the lesions visualized with MRI and the lesions found during surgery in 9/16 patients. The interobserver agreement for lesion detection was good at 1.5 T MRI (κ = 0.69) and 7.0 T MRI (κ = 0.62). In five patients, both the 1.5 T and 7.0 T MRI enabled visualization of a lesion on the correct side of the pituitary gland. In three patients, 7.0 T MRI detected a lesion on the correct side of the pituitary gland, while no lesion was visible at 1.5 T MRI. The interobserver agreement of image assessment for 7.0 T MRI in patients with Cushing's disease was good, and lesions were detected more accurately with 7.0 T MRI. (orig.)

    Chronic obstructive pulmonary disease (COPD), a disease manifested by significantly impaired airflow, afflicts ∼14.2 million cases in the United States alone with an estimated 63 million people world-wide. Although there are a number of causes, the predominant cause is excessive tobacco smoke. In fact, in China, there have been estimates of 315,000,000 people that smoke. Other less frequent causes are associated with indirect cigarette smoke, air pollutants, biomass fuels, and genetic mutations. COPD is often associated with heart disease, lung cancer, osteoporosis and conditions can worsen in patients with sudden falls. COPD also affects both innate and adaptive immune processes. Cigarette smoke increases the expression of matrix metalloproteases and proinflammatory chemokines and increases lung titers of natural killer cells and neutrophils. Yet, neutrophil reactive oxygen species (ROS) mediated by the phagocytic respiratory burst and phagocytosis is impaired by nicotine. In contrast to innate immunity in COPD, dendritic cells represent leukocytes recruited to the lung that link the innate immune responses to adaptive immune responses by activating naïve T cells through antigen presentation. The autoimmune process that is also a significant part of inflammation associated with COPD. Moreover, coupled with restricted FEV1 values, are the prevalence of patients with single or multiple infections by bacteria, viruses and fungi. Finally, we focus on one of the more problematic infectious agents, the Gram-negative opportunistic pathogenic bacterium, Pseudomonas aeruginosa. Specifically, we delve into the development of highly problematic biofilm infections that are highly refractory to conventional antibiotic therapies in COPD. We offer a non-conventional, biocidal treatment that may be effective for COPD airway infections as well as with combinations of current antibiotic regimens for more effective treatment outcomes and relief for patients with COPD.

    Twenty seven cases of acute hepatitis 120 of chronic hepatitis 133 of liver cirrhosis 79 of fatty liver 28 of alcoholic liver injury 5 of intrahepatic cholestasis 22 of obstructive jaundice and 100 normal adults were studied. EMI CT 5005 whole body scanner was used to obtain scan of the liver and spleen, and CT number of them was measured in EMI units, so L/S ratio was calculated by dividing both EMI number. In the patients with obesity, the EMI number of the liver and/or spleen were higher than normal controls. In acute hepatitis, EMI number of the liver, spleen and L/S ratio were no significant differences compared with controls. In chronic hepatitis inactive and active type, EMI number of the liver and spleen were no significant differences between chronic hepatitis and controls, but L/S ratio was lower than that of controls. In cirrhosis of the liver, EMI number of the liver and L/S ratio were lower than that of controls, but EMI number of the spleen had no significant differences compared with controls. In patients with fatty liver, EMI number of the liver and L/S ratio were lower than any other diffuse liver diseases. In alcoholic liver injury had no significant differences from normal controls in liver EMI number, spleen EMI number and L/S ratio. In intrahepatic cholestsis, there was weak inverse correlation between liver EMI number and serum total bilirubin, and in obstructive jaundice strong inverse corelation was seen. In diffuse liver diseases, fatty infiltration, liver cell necrosis, fibrosis or jaundice may decrease the EMI number of the liver and/or L/S ratio, but except for fatty liver, it seems difficult to diagnose the diffuse liver diseases by CT scanner.

    Full Text Available Aim: To evaluate the morphological and hemodynamic changes that take place in carotid arteries by colour Doppler in patients presenting with features of stroke. Background and Objectives: Cerebrovascular accidents constitute a major cause of adult mortality. The principal indication for cerebrovascular Doppler examination is stroke prevention. Colour Doppler sonography is a sensitive method for detection of atherosclerotic plaque and provides considerable information about the extent and severity of plaque as well as the resulting diminution of arterial lumen. The main strengths of sonography of carotid arteries are patient comfort, lack of risk and accuracy in detecting carotid stenosis. Material and Methods: A prospective study of Colour Doppler in carotid arteries was carried out for 12 months from 1 st July 2009 to 1 st July 2010. The study was carried out on 40 individuals, suspected of cerebrovascular insufficiency and having one or the other risk factors for cerebrovascular disease. A detailed clinical history, CNS examination findings and evidence of hypertension, diabetes mellitus, hyperlipidemia and ischemic heart disease were noted. Carotid Doppler evaluation was done by using Siemens Antares Ultrasound system. The data gathered were grey scale and Doppler findings of common carotid artery, internal carotid artery and external carotid arteries. Doppler findings were correlated with clinical features and risk factors. Results: In our study of 40 patients, the commonest lesion found was the atherosclerotic plaque. Highest incidence of plaque was seen in males 41% in the age group of 60-70 years and in females 37% in age group of 70-80 years. Cigarette smoking was the most common risk factor (60% associated with stroke/ Transient Ischaemic Attacks (TIA. Hemiparesis was the most common presenting symptom (35% among the symptomatic cases. Atheromatous plaque was most commonly found in the right carotid system (60%. Most common site for

    Lupus disease measures such as the SLE Disease Activity Index (SLEDAI) and the British Isles Lupus Assessment Group (BILAG) Index are challenging to interpret. The Lupus Foundation of America-Rapid Evaluation of Activity in Lupus (LFA-REAL) is intended to provide an efficient application of anchored visual analogue scores, each representing the individual severity of active symptoms, with the sum of individual scores deriving an overall disease activity assessment. To compare the performance of LFA-REAL to SLE disease activity assessments and compare scores between trained lupus clinical investigators and clinicians. Investigators scored the SLEDAI, BILAG, PGA, and LFA-REAL, while the clinicians scored the LFA-REAL. The level of agreement between physicians and instruments was determined. The study included 99 patients, 93% women, 31% Caucasian, 43.4 (±13.2) years old. At the first visit, the SLEDAI was 5.5 (±4.5), BILAG 6.7 (±7.8), and PGA 33.6 (±24.5). The investigator REAL was 46.2 (±42.9), and clinician REAL 56.1 (±53.6). At the second visit, the investigator REAL was 41.3 (±36.7), and clinician REAL 48.3 (±42.6). Total REAL scores correlated positively with PGA, SLEDAI, and BILAG (ρ 0.58-0.88, p 0.7 for musculoskeletal, mucocutaneous, and renal BILAG domains. The intra-class correlation coefficient between the REAL scores of investigators and clinicians was 0.79 for Visit1 (p < 0.001) and 0.86 for Visit2 (p < 0.001). The LFA-REAL provides a reliable surrogate for more complicated disease activity measures when used by lupus clinical investigators or clinicians. This article is protected by copyright.

    2016-05-01

    The clinical evaluation of patients with tinnitus differs based on whether the tinnitus is subjective or objective. Subjective tinnitus is usually associated with a hearing loss, and therefore, the clinical evaluation is focused on an otologic and audiologic evaluation with adjunct imaging/tests as necessary. Objective tinnitus is divided into perception of an abnormal somatosound or abnormal perception of a normal somatosound. The distinction between these categories is usually possible based on a history, physical examination, and audiogram, leading to directed imaging to identify the underlying abnormality.

    A clinical pharmacist is a key member of the antimicrobial multidisciplinary team involved in patients' pharmacotherapy monitoring. The aim of this study was to determine the frequency and type of medication errors, the type of clinical pharmacy interventions, acceptance of pharmacist interventions by health-care provider team, nursing staff satisfaction with clinical pharmacy services, and the probable impact of clinical pharmacy interventions on decreasing direct medication costs at an infectious diseases ward in Iran. All clinical pharmacist interventions such as preventing medication errors were recorded in a previously designed pharmacotherapy monitoring forms. Direct medication cost of patients admitted during the study period was compared with that of subjects hospitalized at the same ward during the year before the intervention period to determine the impact of clinical pharmacy interventions on direct medication costs. The 3 most frequent medication error types were incorrect dose (35.5%), omission error (24.3%), and incorrect medication (14.3%). The mean number of clinical pharmacist intervention per patient was 3.2. Forty percent of clinical pharmacists' interventions are moderate to major clinical significant. Thirty nine percent of clinical pharmacist's interventions had moderate to major financial benefits in present study. The direct medication cost per patient was decreased about 3.8% following clinical pharmacist's interventions. Our data demonstrated that incorrect dose was the most frequent medication error in the infectious diseases ward. Major portion of clinical pharmacist interventions were accepted by physicians and nursing staff. Clinical pharmacist interventions non-significantly decreased the direct medication cost of patients.

Measurement of this enzyme activity has been an available tool for monitoring therapy of Gaucher disease. The degree of elevation of chitotriosidase is useful for differential diagnosis of Gaucher disease and Niemann Pick A/B. However the potential utility of this chitotriosidase assay depends on the frequency of deficient chitotriosidase activity in a particular population. We therefore aim to study the clinical utility of this assay Gaucher and Niemann Pick A/B diseases in the backdrop of chitotriosidase deficiency in our population. The study comprises 173 patients with clinical suspicion of either Gaucher disease (n=108) or Niemann Pick A/B (n=65) and 92 healthy controls. The plasma samples of controls, Gaucher disease, and Niemann Pick A/B showed chitotriosidase deficiency of 12%, 25% and 27% respectively. The degree of elevation of chitotriosidase in Gaucher disease and Niemann Pick A/B patients is 40-326 (11,325.7±6395.4nmol/h/ml) and 7-22 folds (1192.5±463.0nmol/h/ml) respectively. In view of these findings of distinguishable fold elevation of chitotriosidase in Gaucher disease or Niemann Pick A/B, it can be a potential surrogate differential diagnostic marker for these groups of diseases, except in the patients in whom this enzyme is deficient.

    In order to evaluate briefly the relative 3-dimensional distribution of /sup 201/Tl in the myocardium, a 2-dimensional polar map was developed from short axis tomograms of single-photon emission computed tomography (SPECT) using circumferential profile analysis. The data collected from 180 deg rotational scan around a body were used in clinical study to acquire the projection data in a short time, although, with a heart phantom study, there was more uniformity with the 360 deg collection than with 180 deg collection. So, the polar map of relative distribution and % washout rate (% WR) were created from 180 deg data collection. To detect ischemic area, the lower limit (M-SD) of the profile curve in 10 normal subjects was processed and compared with that of patients. Then, abnormal /sup 201/Tl distribution and % WR were identified comparing each patient's profile with the corresponding normal lower limits. In 24 patients with myocardial infarction, defect score (DS), estimated as infarcted size from the relative polar map, was compared with the size of abnormal wall motion in left ventriculography. There was a good correlation (r = 0.834) between them. Also, there were close correlations between DS and regional contraction (r = -0.869), and between DS and left ventricular ejection fraction (r = -0.775) respectively. In 24 patients with non-MI angina pectoris, the diagnostic sensitivity of exercise induced ischemia was 65 % and accuracy was 76 % by relative distribution map. However, the sensitivity of % WR map was superior (84 %) to that of relative map, especially in the patients with mild ischemia and multi-vessel disease. In conclusion, this comprehensive polar map method represented well a 3-dimensional myocardial distribution of /sup 201/Tl. The clinical usefulness in determination of infarct size and in diagnosis of myocardial ischemia were evaluated.

    Full Text Available In a world experiencing profound technological and socio-political changes in areas of knowledge and capacity, healthcare can not remain static. A new kind of professional is required, whose practice is based on ethics, scientific standards, integrity, citizenship, and health promotion, who develops skills beyond healthcare, such as decision making, communication,leadership, management, and continuing education. No single method can assess all of these elements (knowledge, skills, and attitudes, and only a combination of methods is able to produce a valid evaluation. An alternative method exists: structured clinical assessments based on observation of "to do, or how to do" that aim to complete this evaluation by focusing attention on the performance of specific skills. In order to broaden the scope of evaluation methods that have been used in health education, this article, a literature review, intends to offer readers an overview of the diverse types of structured clinical evaluation, emphasizing Objective Structured Clinical Examination, the most widely used in Brazil, with a goal of advancing opportunities for health professionals to make use of this evaluative tool.

    Wilson's disease is a hereditary autosomal recessive disorder of copper metabolism,characterized by copper accumulation in the liver and brain. This rare entity, which has a broad clinical spectrum, is often difficult to diagnose and should therefore always be suspected in patients with liver disease of unclear cause. We describe two types of manifestation of liver disease in two patients; the first developed fulminant hepatic failure requiring urgent liver transplantation and the second showed advanced chronic liver disease and received standard medical treatment. The objective of this clinical observation is to analyze the diagnosis of Wilson's disease in two patients with distinct onset, illustrating the broad clinical spectrum of the disease, and its treatment.

    Huntington disease (HD) is an autosomal dominant, adult-onset, progressive neurodegenerative disease characterized by the triad of abnormal movements (typically chorea), cognitive impairment, and psychiatric problems. It is caused by an expanded CAG repeat in the gene encoding the protein huntingtin on chromosome 4 and causes progressive atrophy of the striatum as well as cortical and other extrastriatal structures. Genetic testing has been available since 1993 to confirm diagnosis in affected adults and for presymptomatic testing in at-risk individuals. This review covers HD signs, symptoms, and pathophysiology; current genetic testing issues; and current and future treatment strategies.

    We examined the prognostic value of stress echocardiography appropriateness criteria for evaluation of valvular heart disease in 100 consecutive patients. Of the studies, 49%, 36%, and 15% were classified as appropriate, uncertain, and inappropriate, respectively. Over a median of 12.6 months, 24 events (12 deaths and 12 heart failure admissions) occurred. The 12-month event-free survival was significantly reduced in patients with appropriate or uncertain studies compared with patients with inappropriate studies (p = 0.04 and p = 0.005, respectively). There was no survival difference between patients with an appropriate or uncertain indication (p = 0.1). The only independent predictors of events were a positive stress echocardiogram (hazard ratio: 15.5, p valvular heart disease provide the ability to differentiate between patients at high- (appropriate group) and low- (inappropriate group) risk of cardiac events. Reclassification of the uncertain group may improve the differential value of these criteria.

    Full Text Available Intravesical prostatic protrusion (IPP has emerged as a new prostatic morphometric parameter of significance to aid the clinicians in various aspects of managing the patients with some diseases of the lower urinary tract and the prostate. These include but may not be limited to its role in such conditions as: bladder outlet obstruction, trial without catheter, medical treatment effect, progression of lower urinary tract symptoms related to benign prostatic hypertrophy (LUTS/BPH, risk factor for bladder stone in BPH, overactive bladder, prostate carcinoma, and early urinary continence recovery after laparoscopic radical prostatectomy. In this review, I will try to summarize the different researchers' efforts on the potential practical application of this clinical tool. Technology is ever evolving to help us in the diagnosis and management of our patients. However, we as clinicians should contemplate their cost and possible suffering for the patient by wise and judicious utilization based on our clinical experience and tools. IPP seems to be one such promising clinical tool.

    To determine the most appropriate indices to evaluate the disease activity and damage in patients with sytemic lupus erythematosus (SLE). A systematic literature search was performed to identify validation studies of indices used to evaluate disease activity and damage. We collected information for each instrument on every aspect of validation including feasibility, reliability, validity and sensitivity to change using ad hoc forms. A total of 38 articles were included addressing the validation of 6 composite indices to evaluate disease activity (BILAG, ECLAM, SLAM, SLEDAI, LAI and SLAQ); and 3 indices to evaluate damage (SLICC/ACE-DI, LDIQ and BILD). Only the SLAQ, LIDIQ and the BILD were self-administered. Feasibility and internal consistency was only studied in 3 indices (BILAG, SLAQ and SDI) with a Cronbach's α ranging from 0.35 to 0.87. The intra-observer reliability was examined by the intraclass correlation coefficient for BILAG with a result of 0.48 (95%CI: 0,23-0,81) and using analysis of variance for SLAM-R (0,78), SLEDAI (0,33) and the LAI (0,81). The inter-observer feasibility was evaluated using the correlation coefficient for ECLAM (0,90-0,93), the SLAM (0,86) and MEX-SLEDAI (0,97-0,89). The construct validity was examined by means of convergence with other instruments, specifically with global assessment by the physician, with similar results between indices (0,48-0,75). Lastly, responsiveness was tested in all indices except LAI, SDI and LDIQ, with a standardized response mean ranging from 0.12 to 0.75. Although multiple instruments have been validated for use in SLE it was not possible to find direct evidence of which is the most appropriate. BILAG and SLEDAI, with moderate feasibility and low responsiveness, are the 2 indices with a most complete validation and more extensively used. Copyright © 2013 Elsevier España, S.L.U.

    The clinical practice guidelines for the prevention, diagnosis, evaluation and treatment of chronic kidney disease mineral and bone disorders (CKD-BMD) in adults, of the Latin American Society of Nephrology and Hypertension (SLANH) comprise a set of recommendations developed to support the doctor in the management of these abnormalities in adult patients with stages 3-5 kidney disease. This excludes changes associated with renal transplantation. The topics covered in the guidelines are divided into four chapters: 1) Evaluation of biochemical changes, 2) Evaluation of bone changes, 3) Evaluation of vascular calcifications, and 4) Treatment of CKD-MBD. The guidelines are based on the recommendations proposed and published by the Kidney Disease: Improving Global Outcomes (KDIGO) for the prevention, diagnosis, evaluation and treatment of CKD-MBD (KDIGO Clinical practice guidelines for the diagnosis, evaluation, prevention and treatment of Chronic Kidney Disease Mineral and Bone Disorder [CKD-MBD]), adapted to the conditions of patients, institutions and resources available in Latin America, with the support of KDIGO. In some cases, the guidelines correspond to management recommendations directly defined by the working group for their implementation in our region, based on the evidence available in the literature. Each chapter contains guidelines and their rationale, supported by numerous updated references. Unfortunately, there are few controlled studies with statistically sufficient weight in Latin America to support specific recommendations for the region, and as such, most of the references used correspond to studies carried out in other regions. This highlights the need to plan research studies designed to establish the current status of mineral and bone metabolism disorders in Latin America as well as defining the best treatment options for our population.

    Nakamura, Ken; Aminoff, Michael J

    2007-02-01

    Huntington's disease is a devastating disorder with no known cure. The disease results from an expanded sequence of CAG repeats in the huntingtin gene and leads to a movement disorder with associated cognitive and systemic deficits. Huntington's disease is diagnosed by genetic testing and disease progression can be followed with a variety of imaging modalities. The accumulation of aggregated huntingtin with associated striatal degeneration is evident at autopsy. The pathophysiology of Huntington's disease remains unknown, although protein aggregation, excitotoxicity, deficits in energy metabolism, transcriptional dysregulation and apoptosis may all be involved. Current pharmacologic therapy for Huntington's disease is limited and exclusively symptomatic. However, the disease is being heavily researched, and a wide range of disease-modifying therapies is currently under development. The efficacy of these therapies is being evaluated in transgenic models of Huntington's disease and in preliminary clinical trials.

    Fabry disease is an X-linked multisystemic lysosomal-storage condition. We describe a large family with a novel GLA mutation: p.M187R/g7219 T>G. Anamnesis/physical-exam, blood/urine analysis, α-Gal-A activity and/or genetic study of at-risk individuals and multidisciplinary evaluation in confirmed cases. 4 males and 13 heterozygous-females displayed the mutation. Cardiac/renal/neurological disease was diagnosed at a mean age of 41/29/39 years in males and 51/56/46 years in females. Onset mean age was 20 years versus 42 years. 9/15 had cardiomyopathy. Delta wave suggestive of accessory pathway was identified in 1 male and 2 females. 1 female had cardiac arrest (ventricular fibrillation, 61 years). 2 females and 1 male died suddenly (63, 64 and 57 years). Cardiac-subscore of Mainz Severity-Score-Index was severe for males and females over 40 years. 4/15(26%) developed early renal disease. 2 males needed dialysis. 1 male died at 69 years in spite of kidney-heart transplant. We describe the largest genetically confirmed Spanish family using multidisciplinary evaluation and MSSI calculation. The novel mutation p.M187R/g7219 T>G is associated with a particularly malignant cardiac phenotype in males and females over 40 years. Severity was higher than that of the largest Spanish FOS-cohort. Short-PR with delta is being reported for the first time. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    In this study, the conditions of patients to which cerebral revascularization through anastomosis of internal and external carotid arteries is applicable were investigated. In the first part, classification of the degree of cerebrovascular disease was attempted using positron emission tomography (PET) and in the second, cerebral blood circulation was evaluated using cerebral SPECT to consider in respect of advisability of the revascularization surgery. Since cerebral ischemia tends to be induced by enhancement of cerebral oxygen uptake, cerebral revascularization was thought to be restricted to the patients with cerebrovascular disease in stage 2. So, cerebral blood flow, cerebral blood volume and cerebral oxygen metabolism were compared among the patients in stage 1 and stage 2, and the normal control. The blood flow was decreased with the severity of disease and lowest in the patients of stage 2. There were significant differences in the oxygen metabolism and blood volume between the patient stage 1 and the control. The cerebral blood flow in patient in stage 2 was decreased to a level below the self-control range, leading to an increase in the cerebral oxygen uptake. Therefore, it was concluded that the severity of cerebrovascular disease could be estimated with cerebrocirculation index and vasodilation ability determined by cerebral SPECT. Patients of which cerebral blood flow is decreased by more than 28.0% can be regarded as the patient in stage 2. When cerebral blood volume determined by IMP-ARG method and PET method and was compared, underestimation was 34.5% for plane phantom and 11% for cranial pseudo phantom. Further classification would be made on the basis of vascular response under the conditions of Diamox loading and it was concluded that cases of which decrease in cerebral blood flow is 10% or less were applicable to cerebral revascularization.

    There is a critical need for improved diagnosis of tuberculosis in children, particularly in young children with intrathoracic disease as this represents the most common type of tuberculosis in children and the greatest diagnostic challenge. There is also a need for standardized clinical case definitions for the evaluation of diagnostics in prospective clinical research studies that include children in whom tuberculosis is suspected but not confirmed by culture of Mycobacterium tuberculosis. A panel representing a wide range of expertise and child tuberculosis research experience aimed to develop standardized clinical research case definitions for intrathoracic tuberculosis in children to enable harmonized evaluation of new tuberculosis diagnostic technologies in pediatric populations. Draft definitions and statements were proposed and circulated widely for feedback. An expert panel then considered each of the proposed definitions and statements relating to clinical definitions. Formal group consensus rules were established and consensus was reached for each statement. The definitions presented in this article are intended for use in clinical research to evaluate diagnostic assays and not for individual patient diagnosis or treatment decisions. A complementary article addresses methodological issues to consider for research of diagnostics in children with suspected tuberculosis.

    Matthias A Mutke

    Full Text Available INTRODUCTION: In brain perfusion imaging, arterial spin labeling (ASL is a noninvasive alternative to dynamic susceptibility contrast-magnetic resonance imaging (DSC-MRI. For clinical imaging, only product sequences can be used. We therefore analyzed the performance of a product sequence (PICORE-PASL included in an MRI software-package compared with DSC-MRI in patients with steno-occlusion of the MCA or ICA >70%. METHODS: Images were acquired on a 3T MRI system and qualitatively analyzed by 3 raters. For a quantitative analysis, cortical ROIs were placed in co-registered ASL and DSC images. Pooled data for ASL-cerebral blood flow (CBF and DSC-CBF were analyzed by Spearman's correlation and the Bland-Altman (BA-plot. RESULTS: In 28 patients, 11 ASL studies were uninterpretable due to patient motion. Of the remaining patients, 71% showed signs of delayed tracer arrival. A weak correlation for DSC-relCBF vs ASL-relCBF (r = 0.24 and a large spread of values in the BA-plot owing to unreliable CBF-measurement was found. CONCLUSION: The PICORE ASL product sequence is sensitive for estimation of delayed tracer arrival, but cannot be recommended to measure CBF in steno-occlusive disease. ASL-sequences that are less sensitive to patient motion and correcting for delayed blood flow should be available in the clinical setting.

  20. Clinical and Histologic Mimickers of Celiac Disease.

    2017-08-17

    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.

    Full Text Available Patients involved on coeliac disease (CD have atypical symptoms and often remain undiagnosed. Specific oral manifestations are effective risk indicators of CD and for this reason an early diagnosis with a consequent better prognosis can be performed by the dentist. There are not researches analysing the frequency of these oral manifestations in potential coeliac patients. The aim of this study is to investigate the oral hard and soft tissue lesions in potential and ascertained coeliac children in comparison with healthy controls. 50 ascertained children, 21 potential coeliac patients, and 54 controls were recruited and the oral examination was performed. The overall oral lesions were more frequently present in CD patients than in controls. The prevalence of oral soft tissue lesions was 62% in ascertained coeliac, 76.2% in potential coeliac patients, and 12.96% in controls (P<0.05. Clinical dental delayed eruption was observed in 38% of the ascertained coeliac and 42.5% of the potential coeliac versus 11.11% of the controls (P<0.05. The prevalence of specific enamel defects (SED was 48% in ascertained coeliac and 19% in potential coeliac versus 0% in controls (P<0.05; OR=3.923. The SED seem to be genetically related to the histological damage and villous atrophy.

    Objectives: We evaluated the feasibility of highfield lung-MRI at 3.0 T. A comparison with Computed Tomography (CT) and clinical data regarding the assessment of inflammatory activity in patients with diffuse lung disease was performed. Material and methods: Prospective evaluation of 21 patients (15 males, 6 females, 43-80 y) with diffuse lung diseases who underwent clinical work-up inclusive laboratory tests, lung-function tests and transbronchial biopsy. After routine helical CT (additional 12 HRCT) a lung-MRI (3.0 Intera, Philips Medical Systems, Best, The Netherlands) using a T2-weighted, cardiac and respiratory triggered Fast-Spinecho-Sequence (TE/TR = 80/1500-2500 ms, 22 transverse slices, 7/2 mm slice-thickness/-gap) was performed. A pneumologist classified the cases into two groups: A = temporary acute interstitial disease or chronic interstitial lung disease with acute episode or superimposed infection/B = burned out interstitial lung disease without activity. Two blinded CT-radiologists graded the cases in active/inactive disease on the basis of nine morphological criteria each. A third radiologist rated the MRI-cases as active/inactive, depending on the signal-intensities of lung tissues. Results: The pneumologist classified 14 patients into group A and 7 patients into group B. Using CT, 6 cases were classified as active, 15 cases as inactive disease. With MRI 12 cases were classified as active and 9 cases as inactive. In the complete group of 21 patients MRI decisions and CT decisions respectively were false positive/false negative/correct in 2/4/15 respectively 0/8/13 cases. Correct diagnoses were obtained in 72% (MRI) respectively 62% (CT). In the subgroup of 12 cases including HRCT, MRI respectively CT were false positive/false negative/correct in 2/1/9 respectively 0/5/7 cases. Correct diagnoses were obtained in 75% (MRI) respectively 58% (CT). Conclusion: Highfield MRI of the lung is feasible and performed slightly better compared to CT in the

    A method for quantifying the uptake of Tc-99m-labeled phosphate complexes in the femoral head has been clinically evaluated, being used specifically for studying the uptake of these bone-seeking agents in Perthes's disease. The analysis depends on the selection, by computer program, of a reliable reference area in the femoral shaft, which is then compared with the mean uptake from each femoral head. The femoral-head activity is then represented as an uptake ratio. These ratios, together with a fixed contour representing the uptake in the femoral-head regions, provide more clinical information than the radiograph or scintiphoto, particularly in the early stages of unilateral or bilateral femoral-head disease and during followup. No correlation has been found between these ratios and qualitative techniques for assessing Perthes' disease by radiograph. From the quantitative data so far obtained it is clear that osteotomy reduces the vascularity of the femoral head, and in certain cases this reduction persists for some years. Tc-99m-labeled diphosphonate compounds were used in more recent studies, and a significant increase in sensitivity was obtained, compared with earlier polyphosphate data.

    The objective of this study is to describe the interstitial lung disease (ILD) in rheumatoid arthritis (RA) patients of China, and to study clinical significance of high-resolution computed tomography (HRCT) in evaluation and treatment. One hundred and ten Chinese patients (79 women and 31 man) diagnosed with RA between December 2008 to November 2009 were analyzed. According to the HRCT, 47 (42.73%) RA patients were diagnosed as ILD. Old age, smoking and pulmonary rales were closely related to ILD (P pulmonary nodules (11.82%), emphysema (9.09%), bronchiectasis (3.64%), subpleural nodules (11.82%) and pleural thickening (24.55%). In treatment, honeycombing and subpleural nodules were more common in patients with methotrexate (MTX) and/or leflunomide treatment than without (P 0.05). Pulmonary involvement is common in RA patients, and it is suggested that HRCT could be a sensitive and useful way in evaluating the lung of RA patients.

    2017-08-17

    Huntington's disease (HD) is a fully penetrant neurodegenerative disease caused by a dominantly inherited CAG trinucleotide repeat expansion in the huntingtin gene on chromosome 4. In Western populations HD has a prevalence of 10.6-13.7 individuals per 100,000. It is characterised by cognitive, motor and psychiatric disturbance. At the cellular level mutant huntingtin results in neuronal dysfunction and death through a number of mechanisms, including disruption of proteostasis, transcription and mitochondrial function and direct toxicity of the mutant protein. Early macroscopic changes are seen in the striatum with involvement of the cortex as the disease progresses. There are currently no disease modifying treatments therefore supportive and symptomatic management is the mainstay of treatment. In recent years there have been significant advances in understanding both the cellular pathology and the macroscopic structural brain changes that occur as the disease progresses. In the last decade there has been a large growth in potential therapeutic targets and clinical trials. Perhaps the most promising of these are the emerging therapies aimed at lowering levels of mutant huntingtin. Antisense oligonucleotide therapy is one such approach with clinical trials currently underway. This may bring us one step closer to treating and potentially preventing this devastating condition.

    Context An increase in enzyme lactate dehydrogenase (LDH) in serum is a negative prognostic factor for survival in cats affected by lymphoma. Measuring LDH at the time of diagnosis has been studied for differentiating neoplastic disease from non-neoplastic disease in dogs. Inflammatory bowel disease (IBD) and alimentary lymphoma are common diseases in cats. Objective The aim of this study was to determine whether elevation of total LDH occurred in cats with alimentary lymphoma and non-neoplastic gastrointestinal disease, such as IBD, and to evaluate whether this enzyme is useful in supporting the differential diagnosis of these specific diseases. Materials and Methods A prospective non-randomized controlled study was carried-out in a real world setting of three Italian private veterinary clinics. Seventy-one client-owned cats with a history of chronic gastrointestinal symptoms were enrolled; 33 cats were histologically diagnosed as having alimentary lymphoma and 38 cats as having IBD. Serum samples of total LDH analysis were measured. Results Gender (P = 0.016) and age (P = 0.046) were found to be significant factors influencing the differentiation of serum total LDH between cats with alimentary lymphoma and those with IBD. Despite low diagnostic accuracy in the overall population (63%), a cut-off value of serum total LDH ranging from 0.85- to 1.04-times the upper reference limit showed good capability (accuracy >80%) of differentiating these two conditions in neutered males and cats younger than 8 years of age (AUC: 0.805, 0.833; sensitivities: 76.9%, 83.3%; specificities: 80.0%, 76.5%; PPV: 76.9%, 55.6%; NPV: 80.0%, 92.9%; respectively). Conclusions Although our study showed that gender and age are significant factors in differentiating serum total LDH between cats with alimentary lymphoma and those with IBD, this test had poor diagnostic accuracy in differentiating between these two conditions in the overall population.

    Full Text Available BACKGROUND Coronary artery disease has a major share for cardiovascular disease in a developing country like India, which is in epidemic proportion. There are number of risk factors for development of coronary artery disease. According to INTERHEART study, there were 9 modifiable risk factors with population attributable risk of 90 percent in men and 94 percent in women. Metabolic syndrome cluster of risk factors, which include insulin resistance, subclinical inflammation, increased future risk of diabetes and coronary artery disease. In south Asian people are increased tendency to develop metabolic syndrome because of their high percentage of body fat, abdominal obesity and insulin resistance. Metabolic syndrome has more mortality and morbidity from CAD. It is desirable identifying this subset of patients, which could improve patient or physician adherence to risk-reducing behaviours or interventions and improve clinical outcomes. There are reports in literature on association inflammatory markers and insulin resistance with severity of disease in CAD. There are few studies, which correlated severity of CAD with SYNTAX score in patients with metabolic syndrome, so in these study prospectively evaluated clinical and angiographic profile in patients with CAD in subset patients with metabolic syndrome, CAD severity was assessed with SYNTAX scoring system and thrombus burden was evaluated. MATERIALS AND METHODS Among 101 patients who were diagnosed to have metabolic syndrome according to ATP III guidelines were evaluated in the study. All patients were evaluated by clinical examination including waist circumference, body mass index, routine blood investigations were carried out. Lipid profile, ECG and 2D echo was done. Then, patients were evaluated with coronary angiogram and among patients who underwent coronary angiography, the lesions were classified according to AHA/ACC classification into type A, type B and type C for assessing lesion

    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

    2012-01-01

    Full Text Available Introduction. Graves ophthalmopathy is an autoimmune disease, which is the consequence of thyroid dysfunction. Ocular manifestations occur in 50% of patients with Graves disease. The changes occur due to the inflammatory cell infiltration of retrobulbar fat tissue and extraocular muscles. Ultrasonography of eye orbit provides important information about the condition of retrobulbar adipose tissue and the thickness of extraocular muscles. Objective. The aim of our study was to show the clinical significance of orbital ultrasonography in the diagnostics and follow-up of patients with Graves disease. Methods. The authors examined 154 patients with Graves ophthalmopathy at the Clinic of Ophthalmology of the Clinical Centre in Kragujevac during the period 2008–2010. Ophthalmological examination included visual acuity testing (Snellen chart, biomicroscopy and applanation tonometry, direct and indirect ophthalmoscopy, dry eye testing and exophthalmometry (Hertel. Orbital ultrasonography examination and extraorbital muscle measurement was done by ultrasound B-scan. Results. The disease was more frequent in women (79.87% aged from 36–45 years. Most patients had hyperthyreoidism (54.55%. In relation to the duration of the disease, the most frequent clinical signs were bilateral ptosis, conjunctival chemosis and periorbital edema. According to our data the highest number of patients had enlarged medial straight muscle. Conclusion. Graves ophthalmopathy is the most frequent sign of thyroid disease. By orbital ultrasonography we detected extended echogram and measured the thickness of the extraocular muscle. Computerized tomography and magnetic resonance scan were utilized for cases of insufficiently manifested clinical signs of the disease. The advantages of ultrasonography lie in easy handling, patients’ comfort, short time of examination and possibilities of repetition.

    Antiplatelet therapy with aspirin or clopidogrel or both is the standard care for patients with proven coronary or peripheral arterial disease,especially those undergoing endovascular revascularization procedures. However,despite the administration of the antiplatelet regiments,some patients still experience recurrent cardiovascular ischemic events. So far,it is well documented by several studies that in vitro response of platelets may be extremely variable. Poor antiplatelet effect of clopidogrel or high on-treatment platelet reactivity(HTPR) is under investigation by numerous recent studies. This review article focuses on methods used for the ex vivo evaluation of HTPR,as well as on the possible underlying mechanisms and the clinical consequences of this entity. Alternative therapeutic options and future directions are also addressed.

    Full Text Available Abstract Background The objective of this clinical study is to evaluate the safety and effectiveness of the Activ-L Artificial Disc for treatment of single-level degenerative disc disease of the lumbar spine in patients who have been unresponsive to at least six months of prior conservative care. The hypothesis of the study is that the Activ-L Disc is non-inferior to the control (the Charité® Artificial Disc [DePuy Spine] or ProDisc-L® Total Disc Replacement [Synthes Spine] with respect to the rate of individual subject success at 24 months. Individual subject success is a composite of effectiveness and safety. Methods/Design The study proposed is a prospective, randomized, single-masked, controlled, multi-center clinical trial consisting of an estimated 414 subjects with single-level DDD of the lumbar spine (L4/L5, or L5/S1 who have failed to improve with conservative treatment for at least six months prior to enrollment. After enrollment, subjects will be randomized in a 2:1 ratio to either the Activ-L Disc (investigational device or the control (Charité or ProDisc-L. Radiographic endpoints will be evaluated by an independent reviewer at an imaging core laboratory. Each subject will be followed for 5 years post-treatment. Discussion The safety and effectiveness of the Activ-L Artificial Disc for treatment of single-level degenerative disc disease of the lumbar spine will be equivalent to Charité® Artificial Disc [DePuy Spine] or ProDisc-L® Total Disc Replacement [Synthes Spine] at 24 months.

    To describe systematic methods developed over 40 years among over 5000 patients at The Taste and Smell Clinic in Washington, DC to evaluate taste and smell dysfunction. A tripartite methodology was developed. First, methods to determine clinical pathology underlying the multiple disease processes responsible for taste and smell dysfunction were developed. Second, methods to determine biochemical parameters responsible for these pathologies were developed. Third, methods to implement these techniques were developed to form a unified basis upon which treatment strategies can be developed to treat these patients. Studies were performed in 5183 patients. Taste loss was present in 62% of patients, smell loss in 87%. Most patients with taste loss (52%) exhibited Type II hypogeusia; most patients with smell loss (56%) exhibited Type II hyposmia. Sensory distortions were present in 60%. Four common diagnostic entities were found: post influenza-type hyposmia and hypogeusia (27% of patients), idiopathic causes (16%), allergic rhinitis (15%) and post head injury (14%). Regardless of clinical diagnosis the major biochemical abnormality found in most patients (~70%) was diminished parotid salivary and nasal mucus secretion of cAMP and cGMP. Taste and smell dysfunctions are common clinical problems associated with chronic disease processes. These symptoms require a systematic, integrated approach to understand their multiple and complex components. The approach presented here can and has led to effective treatment.

    Parkinson's disease (PD) is a progressive neurodegenerative disorder causing motor and non-motor symptoms that can affect independence, social adjustment and the quality of life (QoL) of both patients and caregivers. Studies designed to find diagnostic and/or progression biomarkers of PD are needed. We describe here the study protocol of COPPADIS-2015 (COhort of Patients with PArkinson's DIsease in Spain, 2015), an integral PD project based on four aspects/concepts: 1) PD as a global disease (motor and non-motor symptoms); 2) QoL and caregiver issues; 3) Biomarkers; 4) Disease progression. Observational, descriptive, non-interventional, 5-year follow-up, national (Spain), multicenter (45 centers from 15 autonomous communities), evaluation study. Specific goals: (1) detailed study (clinical evaluations, serum biomarkers, genetic studies and neuroimaging) of a population of PD patients from different areas of Spain, (2) comparison with a control group and (3) follow-up for 5 years. COPPADIS-2015 has been specifically designed to assess 17 proposed objectives. approximately 800 non-dementia PD patients, 600 principal caregivers and 400 control subjects. Study evaluations: (1) baseline includes motor assessment (e.g., Unified Parkinson's Disease Rating Scale part III), non-motor symptoms (e.g., Non-Motor Symptoms Scale), cognition (e.g., Parkinson's Disease Cognitive Rating Scale), mood and neuropsychiatric symptoms (e.g., Neuropsychiatric Inventory), disability, QoL (e.g., 39-item Parkinson's disease Quality of Life Questionnaire Summary-Index) and caregiver status (e.g., Zarit Caregiver Burden Inventory); (2) follow-up includes annual (patients) or biannual (caregivers and controls) evaluations. Serum biomarkers (S-100b protein, TNF-α, IL-1, IL-2, IL-6, vitamin B12, methylmalonic acid, homocysteine, uric acid, C-reactive protein, ferritin, iron) and brain MRI (volumetry, tractography and MTAi [Medial Temporal Atrophy Index]), at baseline and at the end of follow

    Patients involved on coeliac disease (CD) have atypical symptoms and often remain undiagnosed. Specific oral manifestations are effective risk indicators of CD and for this reason an early diagnosis with a consequent better prognosis can be performed by the dentist. There are not researches analysing the frequency of these oral manifestations in potential coeliac patients. The aim of this study is to investigate the oral hard and soft tissue lesions in potential and ascertained coeliac children in comparison with healthy controls. 50 ascertained children, 21 potential coeliac patients, and 54 controls were recruited and the oral examination was performed. The overall oral lesions were more frequently present in CD patients than in controls. The prevalence of oral soft tissue lesions was 62% in ascertained coeliac, 76.2% in potential coeliac patients, and 12.96% in controls (P coeliac and 42.5% of the potential coeliac versus 11.11% of the controls (P coeliac and 19% in potential coeliac versus 0% in controls (P < 0.05; OR = 3.923). The SED seem to be genetically related to the histological damage and villous atrophy. PMID:25197270

    The work discusses the main clinical features of inflammatory bowel disease (IBD) and the methods to obtain an accurate diagnostic. Nuclear medicine procedures are deeply analysed, with special emphasis in those where clinical experience is larger and that are available for clinical practice in most countries. In the opinion of the authors [sup 99m]Tc-HMPAO is the first choice agent, while [sup 111]In-oxine could be considered as a gold standard for evaluation of new agents. In the context of IBD, the WBC scintigraphy is useful for its diagnosis and the evaluation of disease extension. The evaluation of disease severity deserves further experiences.

    The purpose of this study was to determine under carefully controlled clinical conditions the relative anti-inflammatory and anti-pruritic action of betamethasone as compared with prednisone and a placebo. A total of 130 consecutive patients with atopic dermatitis, primary irritant dermatitis, nummular eczema, allergic eczematous contact dermatitis, sweat retention, seborrheic dermatitis and pruritus were selected for study. Under the conditions of this clinical trial, the samples indicated a difference in anti-inflammatory and anti-pruritic response to the therapeutic agents used. The difference between betamethasone and the placebo was highly significant, and the difference in these measured responses was studied on the basis of a careful evaluation and statistically. The result of this study corroborates statistically our clinical impression regarding the therapeutic effect of betamethasone.

    The use of contracts in grading clinical performance has provided faculty with a solution to two important problems. One has been how to ensure that students are graded consistently among the various faculty who are grading the same clinical component of a course. The second has been to increase the opportunity for individualized attention to student learning needs. We have been pleased to see all the faculty members increase their input and involvement in the continuing modifications of the contract. Although we have taken the major responsibility for the semi-annual revisions of the contract, other faculty members have been increasingly more explicit in their evaluations and suggestions as their experience with the contract has expanded. Their confidence in this method of clinical evaluation has increased with each semester of use. We plan to continue in the refinement of the instrument and will develop materials for the use of other faculty groups who are interested in developing similar contracts. We are also designing a survey to attempt to discover how widespread is the use of contract grading in clinical areas.

    1983-10-01

    Functional dysphonia is a voice impairment without any organic lesion of the phonating system. It may be classified into two categories: functional dysphonia itself where no lesions are found and functional laryngopathies where vocal cord lesions may be attributed to vocal abuse or misuse. The clinical evaluation of a dysphonic patient is performed in three steps: history taking, vocal evaluation, and examination. History taking helps the diagnosis and may be considered also as a therapeutic procedure. Vocal evaluation is oriented toward the voice itself and how it is produced. Then an ENT examination is performed with special attention to the larynx. In functional dysphonia, usually, everything looks normal but there may be signs of inflammation, hyperkinetism, hypokinetism, excessive laryngeal movements, etc. Functional laryngopathies include vocal nodules, laryngitis, polyps, and contact ulcer.

    Objective To evaluate clinical application of therapeutic stenting of digestive diseases as a new approach from conventional management. Methods 115 cases of disorders in digestive system were managed with stents clinically, 148 procedures of intervention in all. The cases were suffering from portal hypertension of cirrhosis, post - operative esophageal stricture, Stricture resulted from esophageal carcinoma, Buddi - Chari syndrome, narrowing of superior mesentery arteries and biliary tract, etc. All had had the strictured or obliterated original natural tube lumen been dilated or recanalized under the guidance of monitoring of the fluoroscope before the stent placement except those receiving TIPS needing the creation of an artificial passage within the liver to place the stent. Results Therapeutic stenting achieves clinical effects completely different from conventional internal medicine and surgery such as portal hypertension by cirrhosis with esophageal varices, megalospleen, ascites improved; jaundis relived then resided and liver function improved and appetite better in postoperative stricture of bile duct; ascites and edema of lower limbs resided in Buddi - Chari syndrom; intestininal distention disappeared, appetite and digestive function improved in stricture in superior mesentery artery; and no dysphagia and easy food intake, appetite improved in patients of stricture of postoperative esophagus and stricture resulted from esophageal carcinoma. Conclusion Therapeutic stenting is clinically unique, dramatically effective, with minor risks and worthy promoting in the management of certain digestive disorders.

    Full Text Available Human parvovirus B19 is a well-known cause of severe conditions in patients with sickle cell disease, but the molecular mechanisms of the infection are insufficiently understood. The different clinical outcome of the acute parvovirus B19 infection in two pediatric patients with sickle cell disease has been examined. One of them developed life-threatening condition requiring emergency transfusions, while the other had asymptomatic infection, diagnosed occasionally. Both cases had high viral load and identical subgenotype, indicating that the viral molecular characteristics play a minimal role in the infection outcome.

    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.

    Obstructive sleep apnoea (OSA) is frequently undiagnosed in patients with heart failure (HF) and coronary artery disease (CAD). Simple and widely available screening tests are needed to diagnose patients with SA. Measurements of thoracic impedance and heart rate variability during 24-hour ECG Holter (H-EKG) monitoring allows to calculate estimated apnoea-hypopnoea index (eAHI). The aim of the research was to assess prevalence of OSA evaluated with the use of H-EKG and determination of its clinical relevance in patients with CAD and ischeamic HF. The study groups comprised of: 30 consecutive patients with ischeamic HF with reduced LVEF (HFrEF) (group A) and 30 patients with CAD (group B). Control group (C) comprised of 30 patients with arterial hypertension but no CAD nor HF. H-ECG monitoring was performed and eAHI was calculated. On the basis of AHI result group A was subdivided to subgroups A1 (eAHI <15) and A2 (eAHI ≥15). Study groups differed with eAHI values (27,9±19,9 vs. 21,8±17,3 vs. 15,7±12,2; p=0,022). Post hoc analysis revealed that eAHI in group A was higher in comparison to group C (27,9±19,9 vs. 15,7±12,2; p=0,006). SA prevalence was higher in group A compared to group C (70,0% vs. 40,0%; p=0,019). Significant but weak correlation between eAHI and LVEDD was found (r=0,282; p<0,05). Subgroups A1 and A2 did not differ in terms of clinical and demographical parameters, HF symptoms, LVEF and NT-proBNP levels. OSA coexists more frequently with HF than with arterial hypertension Significant but weak correlation between eAHI and LVEDD was demonstrated. However, in patients with symptomatic ischeamic heart failure eAHI ≥15 was not related to NYHA class, lower LVEF and higher NT-proBNP levels.

    Institute of Scientific and Technical Information of China (English)

    Ozlem Yonem; Yusuf Bayraktar

    2007-01-01

    Caroli's disease is a rare congenital condition characterized by non-obstructive saccular or fusiform dilatation of larger intrahepatic bile ducts. Cholangitis,liver cirrhosis, and cholangiocarcinoma are its potential complications. The diagnosis of Caroli's disease depends on demonstrating that the cystic lesions are in continuity with the biliary tree which can be showed by ultrasonography, computerized tomography, endoscopic retrograde cholangiopancreatography, percutaneous transhepatic cholangiography or magnetic resonance cholangiopancreatography. Treatment of Caroli's disease relies on the location of the biliary abnormalities. While localized forms confined to one lobe can be treated with surgery, liver transplantation is the only effective modality for diffuse forms. Although a rare disorder;Caroli's disease should always be considered in the differential diagnosis of chronic cholestasis of unknown cause.

    An adolescent with a chronic condition must prepare for transition from the pediatric to the adult health care system. Ideally, transition is a purposeful and coordinated process between the two systems. We sought to evaluate a pediatric rheumatology transition clinic from the perspective of the young adults who attended the clinic. Young adults who attended the IWK Health Centre Pediatric Rheumatology Transition Clinic in Halifax, Nova Scotia, Canada were asked to complete a mail questionnaire. In this clinic an adult rheumatologist joins the pediatric team for the patient's visit. Subjects rated satisfaction with the clinic and how completely a number of items were addressed (e.g. knowledge about disease, self-management, adolescent issues) on a 10 cm visual analog scale (higher scores reflecting more favourable assessment). Compliance with follow-up post-transfer to adult care was assessed by self-report and a chart review. Data were summarized descriptively. The response rate was 34% (51/151). The mean age of respondents was 22 years with the majority diagnosed with juvenile idiopathic arthritis. Most patients were transferred to adult care between the ages of 17 and 20 years. The mean overall satisfaction score with the transition clinic was 7.3 ± 2.6. There was significant variability regarding how well individual transition-related items were perceived to have been addressed, with an overall mean of 6.1 ± 3.2. Items which received a majority of scores of > 7 included learning about side effects of medications, learning to live with their disease, confidence in disease management, and control of disease at transfer. Items rated as rheumatology. Most young adults reported overall satisfaction with the transition clinic, however their perception of how adequately various transition issues were addressed was quite variable. It appears that there were some perceived deficits in the care that was provided in all areas, but possibly more so in

    Challenges remain in translating the well-established evidence for management of cardiovascular disease (CVD) risk into clinical practice. Although electronic clinical decision support (CDS) systems are known to improve practitioner performance, their development in Australian primary health care settings is limited. Study aims were to (1) develop a valid CDS tool that assists Australian general practitioners (GPs) in global CVD risk management, and (2) preliminarily evaluate its acceptability to GPs as a point-of-care resource for both general and underserved populations. CVD risk estimation (based on Framingham algorithms) and risk-based management advice (using recommendations from six Australian guidelines) were programmed into a software package. Tool validation: Data from 137 patients attending a physician's clinic were analyzed to compare the tool's risk scores with those obtained from an independently programmed algorithm in a separate statistics package. The tool's management advice was compared with a physician's recommendations based on a manual review of the guidelines. Field test: The tool was then tested with 21 GPs from eight general practices and three Aboriginal Medical Services. Customized CDS-based recommendations were generated for 200 routinely attending patients (33% Aboriginal) using information extracted from the health record by a research assistant. GPs reviewed these recommendations during each consultation. Changes in CVD risk factor measurement and management were recorded. In-depth interviews with GPs were conducted. Validation testing: the tool's risk assessment algorithm correlated very highly with the independently programmed version in the separate statistics package (intraclass correlation coefficient 0.999). For management advice, there were only two cases of disagreement between the tool and the physician. Field test: GPs found 77% (153/200) of patient outputs easy to understand and agreed with screening and prescribing

    Full Text Available Abstract Background The main function of the kidneys is to remove waste products and excess water from the blood. Loss of kidney function leads to various health issues, such as anemia, high blood pressure, bone disease, disorders of cholesterol. The main objective of this database system is to store the personal and laboratory investigatory details of patients with kidney disease. The emphasis is on experimental results relevant to quantitative renal physiology, with a particular focus on data relevant for evaluation of parameters in statistical models of renal function. Description Clinical database of kidney diseases (CDKD has been developed with patient confidentiality and data security as a top priority. It can make comparative analysis of one or more parameters of patient’s record and includes the information of about whole range of data including demographics, medical history, laboratory test results, vital signs, personal statistics like age and weight. Conclusions The goal of this database is to make kidney-related physiological data easily available to the scientific community and to maintain & retain patient’s record. As a Web based application it permits physician to see, edit and annotate a patient record from anywhere and anytime while maintaining the confidentiality of the personal record. It also allows statistical analysis of all data.

    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.

    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 interventions for neurologic disease, based primarily on the new Guidelines for Stem Cell Research and Clinical Translation released by the International Society for Stem Cell Research in May 2016. Important considerations in the ethical translation of stem cells to clinical practice include regulatory oversight, conflicts of interest, data sharing, the nature of investigation (e.g., within vs outside of a clinical trial), informed consent, risk-benefit ratios, the therapeutic misconception, and patient vulnerability. To help guide the translation of stem cells from the laboratory into the neurosurgical clinic in an ethically sound manner, we present an ethical discussion of these major issues at stake in the field of stem cell clinical research for neurologic disease. © 2016 American Academy of Neurology.

  16. Clinical subgroups in bilateral Meniere disease

    OpenAIRE

    2016-01-01

    Meniere disease (MD) is a heterogeneous clinical condition characterized by sensorineural hearing loss, episodic vestibular symptoms and tinnitus associated with several comorbidities such as migraine or autoimmune disorders (AD). The frequency of bilateral involvement may range from 5-50% and it depends on the duration of the disease. We have performed a two-step cluster analysis in 398 patients with bilateral MD to identify the best predictors to define clinical subgroups with a potential d...

    Full Text Available Dermatomyositis (DM is a chronic inflammatory disorder of the skin and muscles. Evidence supports that DM is an immune-mediated disease and 50-70% of patients have circulating myositis-specific auto-antibodies. Gene expression microarrays have demonstrated upregulation of interferon signaling in the muscle, blood, and skin of DM patients. Patients with classic DM typically present with symmetric, proximal muscle weakness, and skin lesions that demonstrate interface dermatitis on histopathology. Evaluation for muscle inflammation can include muscle enzymes, electromyogram, magnetic resonance imaging, and/or muscle biopsy. Classic skin manifestations of DM include the heliotrope rash, Gottron′s papules, Gottron′s sign, the V-sign, and shawl sign. Additional cutaneous lesions frequently observed in DM patients include periungual telangiectasias, cuticular overgrowth, "mechanic′s hands", palmar papules overlying joint creases, poikiloderma, and calcinosis. Clinically amyopathic DM is a term used to describe patients who have classic cutaneous manifestations for more than 6 months, but no muscle weakness or elevation in muscle enzymes. Interstitial lung disease can affect 35-40% of patients with inflammatory myopathies and is often associated with the presence of an antisynthetase antibody. Other clinical manifestations that can occur in patients with DM include dysphagia, dysphonia, myalgias, Raynaud phenomenon, fevers, weight loss, fatigue, and a nonerosive inflammatory polyarthritis. Patients with DM have a three to eight times increased risk for developing an associated malignancy compared with the general population, and therefore all patients with DM should be evaluated at the time of diagnosis for the presence of an associated malignancy. This review summarizes the immunopathogenesis, clinical manifestations, and evaluation of patients with DM.

    Objectives To evaluate clinical response by baseline disease duration using 2-year data from the AMPLE trial. Methods Patients were randomised to subcutaneous abatacept 125 mg weekly or adalimumab 40 mg bi-weekly, with background methotrexate. As part of a post hoc analysis, the achievement of validated definitions of remission (Clinical Disease Activity Index (CDAI) ≤2.8, Simplified Disease Activity Index (SDAI) ≤3.3, Routine Assessment of Patient Index Data 3 (RAPID3) ≤3.0, Boolean score ≤1), low disease activity (CDAI 6 months). Disease Activity Score 28 (C-reactive protein) 6 months) across multiple clinical measures. Conclusions Abatacept or adalimumab with background methotrexate were associated with similar onset and sustainability of response over 2 years. Patients treated early or later in the disease course achieved comparable clinical responses. Trial registration number NCT00929864, Post-results. PMID:27110385

    Advances in cardiopulmonary bypass equipment have played a critical role in improving outcomes for cardiac surgery patients. Recent advancements include reduced priming volumes, biocompatible coatings and gaseous microemboli handling, as well as the incorporation of an arterial filter into the oxygenator.The purpose of this study was to conduct a comprehensive clinical evaluation of adult oxygenators on the market. Oxygenators assessed included the Sorin Synthesis(®) (n = 30), the Sorin Inspire 6F(®) (n = 10) and Inspire 8F(®) (n = 30), the Terumo FX15(®) (n = 13) and FX25(®) (n = 30), the Maquet Quadrox-i(®) (n = 30) and the Medtronic Fusion(®) (n = 30). Parameters assessed included functional prime volumes, gas exchange, pressure gradients and the effects on patient hematology.The Synthesis had the largest functional prime volume (1426 ml), the FX15 the lowest (956 ml). The Inspire 6F, 8F and Fusion had the greatest O2 transfer. The Sorin oxygenators required the lowest sweep gas flows to obtain a PaCO2 of 40 mmHg. The Sorin oxygenators had the largest pressure gradients. While no differences were observed for hemoglobin and platelet levels post cross-clamp removal, the Sorin Synthesis and Inspire 8F had the largest increases in white blood cell (WBC) counts (122% and 141% of baseline, respectively) and neutrophils (162% and 185% of baseline, respectively).The data demonstrate that no single product is superior in all aspects. The choice of ideal oxygenator depends on the aspect(s) of oxygenator performance the perfusion team believes most clinically acceptable based on available data. © The Author(s) 2015.

    The tumor stem cell theory could explain how patients with metastatic disease show clinical relapse several months after starting treatment due to the survival of a small group of cells with unique characteristics. We examined the distribution and expression of a panel of stem cell markers in human breast cancer primary tumors. Human breast tissues were processed for immunohistochemistry, and RNA was extracted for analysis by quantitative-PCR. Immunohistochemical assay revealed that CD44 was strongly expressed in background endothelia and epithelia. CD133 expression was lost in tumor-associated endothelial cells. Conversely, CD49b was strongly stained in the tumors, associated vessels and ducts but was weakly stained in the background epithelia. q-PCR analysis revealed that CD44 and PSCA were reduced in patients with poor outcome (metastatic disease and death from breast cancer), with a marked reduction in ductal carcinoma, particularly with metastasis to bone although these did not reach significant difference. CD133 was significantly reduced in patients with metastatic disease and was also significantly reduced in patients with ductal carcinoma/bone metastasis. Conversely, CD49F was increased in patients with a poor outcome and those with ductal cancer and bone metastases. This is the first study to determine the distribution and expression pattern of these stem cell markers in human breast cancer. There was a significant association between loss of expression and metastatic disease in patients with breast cancer. Such differential expression may play a part in breast cancer disease progression, and suggests that the current stem cell theory may not hold true for all cancer types.

    The primary aim of this study was to evaluate the current accepted standard clinical endpoint for the earliest-studied HD participants likely to be recruited into clinical trials. Since the advent of genetic testing for HD, it is possible to identify gene carriers prior to the diagnosis of disease, which opens up the possibility of clinical trials of disease-modifying treatments in clinically asymptomatic persons. Current accepted standard clinical endpoints were examined as part of a multi-national, 32-site, longitudinal, observational study of 786 research participants currently in the HD prodrome (gene-positive but not clinically diagnosed). Clinical signs and symptoms were used to prospectively predict functional loss as assessed by current accepted standard endpoints over 8 years of follow up. Functional capacity measures were not sensitive for HD in the prodrome; over 88% scored at ceiling. Prospective evaluation revealed that the first functional loss was in their accustomed work. In a survival analysis, motor, cognitive, and psychiatric measures were all predictors of job change. To our knowledge, this is the first prospective study ever conducted on the emergence of functional loss secondary to brain disease. We conclude that future clinical trials designed for very early disease will require the development of new and more sensitive measures of real-life function. PMID:20623772

  2. Evaluation of primary immunodeficiency disease in children.

    2013-06-01

    One in 2,000 children younger than 18 years is thought to have a primary immunodeficiency disease. Antibody, combined B-cell and T-cell, phagocytic, and complement disorders are the most common types. Children with these diseases tend to have bacterial or fungal infections with unusual organisms, or unusually severe and recurrent infections with common organisms. A family history of primary immunodeficiency disease is the strongest predictor of a person having this type of disease. When an immunodeficiency disease is suspected, initial laboratory screening should include a complete blood count with differential and measurement of serum immunoglobulin and complement levels. The presence of lymphocytopenia on complete blood count suggests a T-cell disorder, whereas a finding of neutropenia suggests a phagocytic disorder. Abnormal serum immunoglobulin levels suggest a B-cell disorder. Abnormalities on assay of the classic or alternative complement pathways suggest a complement disorder. If laboratory results are abnormal, or if clinical suspicion continues despite normal laboratory results, children should be referred for further evaluation. Human immunodeficiency virus infection should also be considered, and testing should be performed, if appropriate; this infection often clinically resembles a T-cell disorder.

    Full Text Available Abstract Background Cost of illness studies show that Parkinson disease (PD is costly for individuals, the healthcare system and society. The costs of PD include both direct and indirect costs associated with falls and related injuries. Methods This protocol describes a prospective economic analysis conducted alongside a randomised controlled trial (RCT. It evaluates whether physical therapy is more cost effective than usual care from the perspective of the health care system. Cost effectiveness will be evaluated using a three-way comparison of the cost per fall averted and the cost per quality adjusted life year saved across two physical therapy interventions and a control group. Conclusion This study has the potential to determine whether targetted physical therapy as an adjunct to standard care can be cost effective in reducing falls in people with PD.

    Accurate diagnosis of bovine respiratory disease (BRD) in beef cattle is a critical facet of therapeutic programs through promotion of prompt treatment of diseased calves in concert with judicious use of antimicrobials. Despite the known inaccuracies, visual observation (VO) of clinical signs is the conventional diagnostic modality for BRD diagnosis. Objective methods of remotely monitoring cattle wellness could improve diagnostic accuracy; however, little information exists describing the accuracy of this method compared to traditional techniques. The objective of this research is to employ Bayesian methodology to elicit diagnostic characteristics of conventional VO compared to remote early disease identification (REDI) to diagnose BRD. Data from previous literature on the accuracy of VO were combined with trial data consisting of direct comparison between VO and REDI for BRD in two populations. No true gold standard diagnostic test exists for BRD; therefore, estimates of diagnostic characteristics of each test were generated using Bayesian latent class analysis. Results indicate a 90.0% probability that the sensitivity of REDI (median 81.3%; 95% probability interval [PI]: 55.5, 95.8) was higher than VO sensitivity (64.5%; PI: 57.9, 70.8). The specificity of REDI (median 92.9%; PI: 88.2, 96.9) was also higher compared to VO (median 69.1%; PI: 66.3, 71.8). The differences in sensitivity and specificity resulted in REDI exhibiting higher positive and negative predictive values in both high (41.3%) and low (2.6%) prevalence situations. This research illustrates the potential of remote cattle monitoring to augment conventional methods of BRD diagnosis resulting in more accurate identification of diseased cattle.

    The Minamata disease was discovered in the Minamata region, Kumamoto Prefecture, Japan, in 1956. Symptoms of this disease included cerebellar ataxia, sensory disturbance, narrowing of the visual field, and hearing and speech disturbances. In 1965, similar conditions were identified in persons living around the Agano River area, Niigata Prefecture, Japan and accordingly termed as the Niigata Minamata disease or the second Minamata disease. Both the diseases have been attributed to poisoning with methyl mercury that was generated during the production of acetaldehyde using mercury as a catalyst. The discharged methyl mercury accumulated in fishes and shellfishes and caused poisoning on consumption. This review discusses the history, clinical presentation including atypical forms, and autopsy findings of the Niigata Minamata disease. In addition, it highlights the problems about criteria for official recognition and the therapeutic trial for this disease.

    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.

    In the present study, the heads of 11 normal subjects and 21 patients affected by hydrocephalus due to three different causes were simulated using fluid-structure interaction (FSI). To validate the results, the calculated diagram of CSF velocity in aqueduct of Sylvius (AS) was compared with the similar velocity diagram measured using Cine PC-MRI for the same subject. After ensuring the agreement of results, other outputs such as CSF pressure were calculated non-invasively using FSI. The intracranial pressure and CSF pressure in AS and behind the optic nerve sheath were in patients 5-5.3 times the value in normal subjects and the ventricular system volume in patients was 10.2-11.1 times the value in normal subjects. However, the difference between the coefficient of variation and the maximum value of pressure and volume in different types of hydrocephalus was small. Furthermore, the difference between CSF stroke volumes in various types of hydrocephalus patients was less than 4.4%. Results showed that the intensity of clinical symptoms was similar in patients with similar CSF pressure and the cause of the hydrocephalus disease didn't have any significant effect on the intensity of patients' clinical symptoms and the manner of changes in effective parameters on disease. It was also found that the relation of CSF pressure and volume was 16.7% greater in patients with non-communicating hydrocephalus than in patients with communicating hydrocephalus. These results enhance the insight into hydrocephalus bio-mechanism and can help to choose the proper treatment method for hydrocephalus patients.

    contraceptives (OCPs) but have not shown improvement in menses, spontaneous ovulation, hirsutism, or acne. Statins reduce total and LDL cholesterol but have no effect on HDL, C-reactive protein, fasting insulin, or homeostasis model assessment of insulin resistance in PCOS women, in contrast to the general population. There have been no long-term studies of statins on clinical cardiac outcomes in women with PCOS. Coronary calcification is more prevalent and more severe in PCOS than in controls. In women under 60 years of age undergoing coronary angiography, the presence of polycystic ovaries on sonography has been associated with more arterial segments with >50% stenosis, but the relationship between PCOS and actual cardiovascular events remains unclear. Therapies for PCOS are varied in their effects and targets and include both nonpharmacologic as well as pharmacologic approaches. Weight loss is the primary therapy in PCOS--reduction in weight of as little as 5% can restore regular menses and improve response to ovulation- inducing and fertility medications. Metformin in premenopausal PCOS women has been associated with a reduction in features of MetS. Clamp studies using ethinyl estradiol/drosperinone combination failed to reveal evidence of an increase in either peripheral or hepatic insulin resistance. Subjects with PCOS have a 1.5-times higher baseline risk of venous thromboembolic disease and a 3.7-fold greater effect with OCP use compared with non-PCOS subjects. There is currently no genetic test to screen for or diagnose PCOS, and there is no test to assist in the choice of treatment strategies. Persistent bleeding should always be investigated for pregnancy and/or uterine pathology--including transvaginal ultrasound exam and endometrial biopsy--in women with PCOS. PCOS women can have difficulty conceiving. Those who become pregnant are at risk for gestational diabetes (which should be evaluated and managed appropriately) and the microvascular complications of diabetes

    American Thyroid Association (ATA) intermediate-risk thyroid cancer patients who achieve an excellent treatment response demonstrate a low risk of structural disease recurrence. Despite this fact, most patients undergo frequent surveillance neck ultrasound (US) during follow-up. The objective of the study was to evaluate the clinical utility of routine screening neck US in ATA intermediate-risk patients documented to have a nonstimulated thyroglobulin less than 1.0 ng/mL and a neck US without suspicious findings after therapy. Retrospective review of 90 ATA intermediate-risk papillary thyroid carcinoma patients treated with total thyroidectomy and radioactive iodine ablation in a tertiary referral center. A comparison between the frequency of finding false-positive US abnormalities and the frequency of identifying structural disease recurrence in the study cohort was measured. Over a median of 10 years, 90 patients had a median of six US (range 2-16). Structural disease recurrence was identified in 10% (9 of 90) at a median of 6.3 years. Recurrence was associated with other clinical indicators of disease in 5 of the 90 patients (5.6%, 5 of 90) and was detected without other signs of recurrence in four patients (4.8%, 4 of 84). False-positive US abnormalities were identified in 57% (51 of 90), leading to additional testing, which failed to identify clinically significant disease. In ATA intermediate-risk patients who have a nonstimulated thyroglobulin less than 1.0 ng/mL and a neck US without suspicious findings after therapy, frequent US screening during follow-up is more likely to identify false-positive abnormalities than clinically significant structural disease recurrence.

  12. Neuroendocrine evaluation of cardiac disease.

    Science.gov (United States)

    Sisson, D David

    2004-09-01

    Current evidence favors the view that regardless of etiology, there is a predictable sequence of neuroendocrine activation that operates in most dogs and cats with progressive heart disease and that it is largely, but not entirely, independent of etiology. The natriuretic peptides and sympathetic nervous system seem to be early responders to developing cardiac and hemodynamic perturbations in both species. BNP plays a particularly prominent role in cats, possibly as a reflection of disease etiology. Shortly thereafter, plasma endothelin concentrations rise, reflecting the impact of the hemodynamic alterations on the vasculature. Endothelin and the natriuretic peptides directly suppress plasma renin release but have divergent effects on aldosterone. Activation of the tissue RAAS may operate early on to further the progression of heart failure, but evidence of plasma RAAS activation occurs comparatively late and near the time of development of overt CHF. Finally, in animals with severe CHF that are prone to hypotension,vasopressin levels may also rise, contributing to the retention of free water and congestion that is refractory to diuretics. Although oversimplified, this scenario seems to be consistent with data obtained in human, canine, and feline patients. These observations provide some impetus for evaluating ACE inhibitors in cats and beta-receptor-blocking drugs in dogs and cats. Perhaps we are also a little closer to identifying useful biochemical markers that can aid in the diagnosis of heart disease, guide therapy, and improve our understanding of the biologic processes occurring in our patients.

    To characterize peripheral neuropathy subtypes, ancillary studies, and immunologic profiles associated with peripheral neuropathies in patients with systemic lupus erythematosus (SLE). In this 25-year study of 2,097 SLE patients, we characterized peripheral neuropathies due to SLE and compared clinical and SLE-related features in patients with versus those without neuropathy. The prevalence of peripheral neuropathies was 5.9% (123 of 2,097 patients), and 66.7% of these patients (82 of 123) had peripheral neuropathies attributable to SLE. We noted that 17.1% of the patients with peripheral neuropathies due to SLE (14 of 82 patients) had small-fiber neuropathy, which is a painful neuropathy not included in the American College of Rheumatology (ACR) neuropsychiatric SLE (NPSLE) case definitions. SLE patients with small-fiber neuropathies could present with unorthodox neuropathic pain patterns not consistent with a stocking-glove distribution and had associated skin biopsy results suggestive of dorsal root ganglion neuronal cell loss. Compared to SLE patients without peripheral neuropathies, those with peripheral neuropathies had lower mean disease activity (P = 0.01) and higher disease damage (P neuropathies, is warranted.

    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.

    The Ledderhose's diseases is a relatively rare and not well known clinical picture. Even there are tight pathomorphological and clinical relations to the Dupuytren's contracture, the genesis is also here quite unknown. Because of inefficiency of conventional therapy the surgical treatment is the only alternative. On the sample of 12 operations in 7 patients from 1979 to 1989 surgical procedure and long-term results are discussed.

    To evaluate cerebral blood flow (CBF) in patients with moyamoya disease, single photon emission computed tomography (SPECT) was performed using acetazolamide-activated {sup 133}Xe inhalation method. In the present investigation, 15 patients were subjected: 6 pediatric cases with the mean age of 10.8 years and 9 adult cases with the mean age of 44.6 years. The regional CBF (rCBF) was measured in the territory of anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA), basal ganglia, and cerebellum. Cerebrovascular acetazolamide reactivity was evaluated from the rCBF measured before and after administration of acetazolamide. Namely, cerebrovascular acetazolamide reactivity was expressed as %CBF and calculated as follows: %CBF=100 x (CBF after acetazolamide administration-CBF at rest)/CBF at rest. rCBF in adult patients was decreased in the cerebral hemisphere, while that in childhood was significantly decreased in the territory of ACA. The %CBF after acetazolamide loading was decreased in the territory of ACA and MCA in both adult and childhood. When cerebral %CBF was compared to the cerebellar %CBF, the ratio of cerebral %CBF and cerebellar %CBF resulted in markedly lower in childhood than adult. rCBF and cerebrovascular acetazolamide reactivity were also measured before and after extracranial and intracranial (EC-IC) bypass surgery in three pediatric moyamoya patients. Although rCBF was increased immediately after EC-IC bypass surgery, the cerebrovascular acetazolamide reactivity remained blunted. These results meant that in the pediatric moyamoya patients cerebrovascular acetazolamide reactivity is more blunted than adult moyamoya patients. Also, the cerebral vessels in moyamoya disease were considered to be dilated to their limitation by the blood supplied through the EC-IC bypass and not to be expandable any more by acetazolamide.

    Full Text Available Background: We investigated whether and to what extent the ratio between circulating fibrinogen (Fg and its degradation products (FDP reflects the severity of coronary artery disease (CAD in type 2 diabetic patients. Methods: Plasma levels of Fg and FDP were determined, and Fg/FDP ratio was calculated in 344 consecutive patients with type 2 diabetes and chest pain on exertion undergoing coronary angiography. The severity of CAD was evaluated by the number of significant CAD (>50% luminal diameter narrowing and Gensini score. Results: Plasma Fg was higher, but Fg/FDP ratio was lower in patients with significant CAD (n = 255 compared with those without (n = 89, due to a disproportionate increase in FDP. Fg and FDP correlated positively, while Fg/FDP ratio negatively, with the number of diseased coronary arteries and the tertile of Gensini score (all P values for trend < 0.01. After adjusting for age, sex, risk factors for CAD, lipid profiles, glycosylated hemoglobin A1c, creatinine, leukocyte count, and high-sensitivity C-reactive protein, Fg/FDP ratio remained an independent determinant for multivessel coronary disease (MVD (odds ratio [OR], 0.869; 95% confidence interval [CI], 0.788-0.958, P = 0.005 and high tertile of Gensini score (OR, 0.797, 95% CI, 0.682-0.930, P = 0.004. The area under the curve of Fg/FDP ratio was larger than that of Fg for predicting the presence of MVD (0.647 vs. 0.563, P = 0.048 and Gensini score ≥ 30 (0.656 vs. 0.538, P = 0.026. Conclusions: Elevated plasma Fg and FDP level and reduced Fg/FDP ratio are associated with presence of CAD, and Fg/FDP ratio is superior to Fg in reflecting severe coronary atherosclerosis for patients with type 2 diabetes.

    Full Text Available Calcium pyrophosphate deposition (CPPD disease is an arthropathy caused by calcium pyrophosphate dihydrate (CPP crystal deposits in articular tissues, most commonly fibrocartilage and hyaline cartilage. According to EULAR, four different clinical presentations can be observed: 1 asymptomatic CPPD; 2 osteoarthritis (OA with CPPD; 3 acute CPP crystal arthritis; 4 chronic CPP inflammatory crystal arthritis. Acute CPP crystal arthritis is characterized by sudden onset of pain, swelling and tenderness with overlying erythema, usually in a large joint, most often the knee, wrist, shoulder, and hip. Occasionally, ligaments, tendons, bursae, bone and the spine can be involved. CPPD of the atlanto-occipital joint (crowned dens syndrome can cause periodic acute cervico-occipital pain with fever, neck stiffness and laboratory inflammatory syndrome. Chronic inflammatory arthritis is characterized by joint swelling, morning stiffness, pain, and high ESR and CRP. The relationship between OA and CPPD is still unclear. The main problem is whether such crystals are directly involved in the pathogenesis of OA or if they are the result of joint degeneration. Diagnosis is based on evaluation of history and clinical features, conventional radiology, and synovial fluid examination. Non-polarized light microscopy should be used initially to screen for CPPD crystals based upon their characteristic morphology, and compensated polarized light microscopy, showing the crystals to be weakly positive birefringent, is recommended for definitive identification, although this last pattern only occurs in about 20% of samples. The main goals of CPPD therapy are control of the acute or chronic inflammatory reaction and prevention of further episodes.

To evaluate the neoplasms and to differentiate benign from malignant lesions by USG characteristics and to correlate with FNAC reports. 4. Role of USG in rapidly growing thyroid lesions: To differentiate haemorrhage into the cystic lesions and rapidly growing malignant tumours. 5. Compare the results of our study with similar studies available in the present literature. MATERIALS & METHODS This study included 75 patients who attended outpatient departments of the Endocrinology, Medical and Surgical Units and also those who were inpatients. RESULTS Broadly pathological conditions of thyroid glands can be divided into nodular and diffuse thyroid diseases. Among Nodular Diseases Majority are benign, only few are malignant. Characteristics of benign lesions are: 1. Well-differentiated margins. 2. Thin complete peripheral sonolucent halo. 3. Coarse peripheral calcifications. Characteristics of malignant nodules are: 1. Ill-defined margins. 2. Thick incomplete peripheral halo. 3. Fine punctuate calcifications. Diffuse Thyroid Diseases 1. Hashimoto’s thyroiditis: Painless diffuse enlargement of thyroid gland usually in women with coarse echotexture and no normal gland tissue. There may be discrete hypoechoic nodules within it with cervical lymphadenopathy. 2. Goitres: a Simple diffuse goitre: Symmetrical enlargement of gland without tenderness or bruit or lymphadenopathy, T3, T4 and TSH are within normal limits and no thyroid autoantibodies in the serum. a Diffuse Toxic goitre: Diffuse enlargement of gland with increased vascularity on colour Doppler study. b Multinodular goitre: Multiple hypoechoic nodule within normal thyroid parenchyma. c Colloid goitre: Present as single or multiple swellings in the thyroid gland.

    Familial Mediterranean fever (FMF) shares a number of features with Behçet's disease (BD), such as their common ethnic origin, etiopathogenetic mechanisms, symptoms, and treatment. Pathergy reaction is accepted as a major criterion in BD. We aimed to determine the frequency of pathergy positivity in FMF patients and compared clinical features between FMF and BD. Pathergy test was performed in patients with FMF, BD, and healthy controls. Diagnostic criteria for FMF and BD were screened in both groups. None of the FMF patients or healthy controls yielded positive pathergy test. Pathergy test was positive in 13 out of 31 (41.9%) of the patients with BD. None of the FMF patients fulfilled the International Study Group criteria for BD. None of the BD patients fulfilled the Livneh diagnostic criteria for FMF. BD and FMF are associated with neutrophilic dermatoses and neutrophil hyper-reactivity. Although pathergy test and erysipelas-like erythema share some histological findings, pathergy test was negative among FMF patients.

    The utilization of disease management (DM) as a minimum standard of care is believed to facilitate pronounced benefits in overall patient outcome and cost management. Randomized clinical trials remain the gold standard evaluative tool in clinical medicine. However, the extent to which contemporary cardiovascular clinical trials incorporate DM components into their treatment or control arms is unknown. Our study is the first to evaluate the extent to which clinical trials incorporate DM as a minimum standard of care for both the intervention and control groups. In total, 386 clinical trials published in 3 leading medical journals between 2003 and 2006 were evaluated. For each study, elements related to DM care, as defined using the American Heart Association Taxonomy, were abstracted and characterized. Our results demonstrate that while the application of DM has increased over time, only 3.4% of the clinical trials examined incorporated all 8 DM elements (and only 11% of such trials incorporated 4 DM elements). A significant association was found between study year and the inclusion of more than 3 elements of DM (chi(2) = 10.10 (3); p = 0.018). In addition, associations were found between study objective and DM criteria, as well as between cohort type and domains described. Our study serves as a baseline reference for the tracking of DM within, and its application to, randomized clinical trials. Moreover, our results underscore the need for broader implementation and evaluation of DM as a minimum care standard within clinical trial research.

    中医药学赖以生存和发展的基础是临床疗效.当前“病证结合”为主的诊疗模式下,传统上以个人经验进行个案前后比较式的疗效判定方法已经不适应中医药学现代化发展的要求,直接用现代医学的临床疗效评价体系,也不适用于中医学的诊疗规律.因此,如何建立符合中医特点的临床疗效评价方法和评价体系已成为临床研究亟待解决的问题.本文总结目前中医临床疗效评价的现状,针对中医临床的特点,认为针对中医临床疗效的评价当分为对中医“法”的疗效评价、对“方”的疗效评价和对“药”的临床疗效评价,并且以对“法”的评价为例进行探讨,进一步提出临床研究方案、证候以及来自患者和其家属的报告等当作为中医临床疗效评价的着力点,为进一步探索符合中医特点的临床疗效评价模式并进行方法学研究提供参考.%Clinical efficacy is the factor to maintain the existence and development of traditional Chinese medicine (TCM). The current disease-syndrome combination model and efficacy determination based on personal experiences comparison before and after the treatment have no longer suit for TCM diagnosis and treatment rules. Therefore, how to establish a clinical efficacy evaluation method and evaluation system which is suitable to TCM features has become an urgent clinical research problem. This paper summarized current status of TCM clinical efficacy evaluation. According to characteristics of TCM clinical practice, the clinical efficacy evaluation for TCM should be divided into "principle" evaluation, "prescription" evaluation and clinical efficacy evaluation of the "medicine." The "principle" evaluation was used as an example to further propose the clinical research program and TCM syndrome. Reports from patients and their family members have been used as important references for TCM clinical efficacy evaluation in order to further

    Full Text Available Introduction-Heart disease complicating pregnancy is considered as a high risk situation. Increased cardiac demands during the course of pregnancy potentially increase morbidity and mortality in women with underlying heart disease. AIM: To determine maternal and fetal outcome in women with heart disease complicating pregnancy, To emphasize on proper protocol for managing pregnancy complicated by heart disease, To correlate the time of booking & NYHA grading with maternal & fetal outcome. Risk of adverse outcome is more in rural population as compared to its urban counterpart. METHOD: A prospective clinical study of 25 cases of pregnancy complicated by heart disease, reporting to tertiary care hospital for delivery, was carried out to find out the incidence and maternal and fetal outcome. RESULTS: The incidence of heart disease in pregnancy in the present study was 0.6%. Most of the women (91% belonged to low socioeconomic class in the rural population. Rheumatic heart lesions constituted 77% of the cases. Mitral stenosis was the commonest lesion in 40% of cases. Ten (40% women delivered spontaneously vaginally at term. Cesarean section was performed in 14 cases (56%. There were 5 maternal deaths. There were no perinatal deaths. CONCLUSION: Early diagnosis of heart disease, regular antenatal check-up, institutional delivery, limiting family size can reduce the maternal and perinatal mortality and morbidity associated with heart disease

    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.

    Meniere disease (MD) is a heterogeneous clinical condition characterized by sensorineural hearing loss, episodic vestibular symptoms, and tinnitus associated with several comorbidities, such as migraine or autoimmune disorders (AD). The frequency of bilateral involvement may range from 5 to 50%, and it depends on the duration of the disease. We have performed a two-step cluster analysis in 398 patients with bilateral MD (BMD) to identify the best predictors to define clinical subgroups with a potential different etiology to improve the phenotyping of BMD and to develop new treatments. We have defined five clinical variants in BMD. Group 1 is the most frequently found, includes 46% of patients, and is defined by metachronic hearing loss without migraine and without AD. Group 2 is found in 17% of patients, and it is defined by synchronic hearing loss without migraine or AD. Group 3, with 13% of patients, is characterized by familial MD, while group 4, that includes 12% of patients, is associated by the presence of migraine in all cases. Group 5 is found in 11% of patients and is defined by AD. This approach can be helpful in selecting patients for genetic and clinical research. However, further studies will be required to improve the phenotyping in these clinical variants for a better understanding of the diverse etiological factors contributing to BMD. PMID:27822199

    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

    Traveller's diarrhea is the most common tourist's disease in the tropics. Therefore epidemiological data for the evaluation of factors influencing the attack rates and the severity of the disease are being required. This paper deals with the data of 1058 Austrian tourists travelling to warm climate countries. 47.3% of all travellers suffered from an episode of traveller's diarrhea during their stay. However, it could be evaluated that besides the destination seasonal influences were very important. Factors like individual hygiene and accommodation did not influence the attack rates. Age and environmental conditions, however, did partially influence the frequency of diarrhea. Furthermore, additional symptoms were interpreted and it could be seen that suspected heterogenicity of etiology leads to a similar pattern of clinical symptoms. Clinical evaluation proves that traveller's diarrhea is commonly not severe, but due to the incidence and duration of the disease it is a major health problem in modern tourism.

    The clinical signs and diagnostic approach are different in the cat as compared with the dog, which has impaired the veterinarian's ability to detect this parasite in the cat. New techniques and methodologies have enabled the cat owner and veterinarian to recognize this potentially severe disease. Although much is now known about the pathophysiology and biology of this parasite in the cat, the practical application and rapid development of this information to daily practice has led to confusion.

    Determine the minimal clinically important change (MCIC), a measure determining the minimum change in scale score perceived as clinically beneficial, for the international restless legs syndrome (IRLS) and restless legs syndrome 6-item questionnaire (RLS-6) in patients with moderate to severe restless legs syndrome (RLS/Willis-Ekbom disease) treated with the rotigotine transdermal system. This post hoc analysis analyzed data from two 6-mo randomized, double-blind, placebo-controlled studies (SP790 [NCT00136045]; SP792 [NCT00135993]) individually and as a pooled analysis in rotigotine-treated patients, with baseline and end of maintenance IRLS and Clinical Global Impressions of change (CGI Item 2) scores available for analysis. An anchor-based approach and receiver operating characteristic (ROC) curves were used to determine the MCIC for the IRLS and RLS-6. We specifically compared "much improved vs minimally improved," "much improved/very much improved vs minimally improved or worse," and "minimally improved or better vs no change or worse" on the CGI-2 using the full analysis set (data as observed). The MCIC IRLS cut-off scores for SP790 and SP792 were similar. Using the pooled SP790+SP792 analysis, the MCIC total IRLS cut-off score (sensitivity, specificity) for "much improved vs minimally improved" was -9 (0.69, 0.66), for "much improved/very much improved vs minimally improved or worse" was -11 (0.81, 0.84), and for "minimally improved or better vs no change or worse" was -9 (0.79, 0.88). MCIC ROC cut-offs were also calculated for each RLS-6 item. In patients with RLS, the MCIC values derived in the current analysis provide a basis for defining meaningful clinical improvement based on changes in the IRLS and RLS-6 following treatment with rotigotine. © 2016 American Academy of Sleep Medicine.

The literature was variable but nevertheless useful for the identification of evaluation standards. These standards are reproduced here in order to add to the literature. We also discuss the areas that would benefit from further research, thus contributing to the discourse on best practice in evaluating clinical coder training programs.

    Recent advances in the understanding of Alzheimer's disease pathogenesis have led to the development of numerous compounds that might modify the disease process. Amyloid β (Aβ) peptide represents an important molecular target for intervention in Alzheimer's disease. Several types of Aβ peptide immunotherapy for Alzheimer's disease are under investigation, direct immunization with synthetic intact Aβ(42) , active immunization involving the administration of synthetic fragments of Aβ peptide conjugated to a carrier protein and passive administration with monoclonal antibodies directed against Aβ peptide. Pre-clinical studies showed that immunization against Aβ peptide can provide protection and reversal of the pathology of Alzheimer's disease in animal models. Indeed, several adverse events have been described like meningoencephalitis with AN1792, vasogenic edema and microhemorrhages with bapineuzumab. Although immunotherapy approaches resulted in clearance of amyloid plaques in patients with Alzheimer's disease, this clearance did not show significant cognitive effect for the moment. Currently, several Aβ peptide immunotherapy approaches are under investigation but also against tau pathology. © 2011 The Authors.

    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.

    Infestation in soft tissue by Echinococcus granulosus is not a common disease, and its diagnosis is based on clinical, laboratory data and radiological findings. The aim of our retrospective study is to give an overview of the different signs and patterns shown by MRI that can be useful in characterizing soft tissue hydatid disease. The MRI images obtained in seven patients with soft tissue and subcutaneous hydatidosis were reviewed. Typical signs of hydatidosis were multivesicular lesions with or without hypointense peripheral ring (''rim sign''). Related to the presence and absence, respectively, of viable scolices in the microscopic exam, daughter cysts were presented either as high signal intensity or low signal intensity on T2-weighted images. Low-intensity detached layers within the cyst and peripheral enhancement with gadolinium-DTPA were also presented. Atypical signs were presented in an infected muscular cyst, a subcutaneous unilocular cyst and several unilocular cysts. Knowledge of the different patterns in MRI of soft tissue hydatid disease can be useful in diagnosing this entity. We observed that the ''rim sign'' is not as common as in other locations, and in addition, MRI seems to be of assistance when evaluating the vitality of the cysts. (orig.)

    2015-01-01

    Parkinson's disease harbours many different tremors that differ in distribution, frequency, and context in which they occur. A good clinical tremor assessment is important for weighing up possible differential diagnoses of Parkinson's disease, but also to measure the severity of the tremor as a basis for further tailored treatment. This can be challenging, because Parkinson's tremor amplitude is typically very variable and context-dependent. Here, we outline how we investigate Parkinson's tremor in the clinic. We describe a simple set of clinical tasks that can be used to constrain tremor variability (cognitive and motor co-activation, several specific limb postures). This may help to adequately characterize the tremor(s) occurring in a patient with Parkinson's disease.

    Full Text Available Chagas disease (CD, caused by the protozoan Trypanossoma cruzi, affects approximately 18 million individuals in the Americas, 5 million of which live in Brazil. Most chronic sufferers have either the indeterminate form of the disease, without organic compromise, or the cardiac or digestive forms. Despite the importance of this disease, there is no information on the effect of nutrition on CD evolution. We evaluated the clinical-nutritional profile of individuals with CD treated at the Tropical Diseases Nutrition Out-Patient Clinic of the Botucatu School of Medicine, UNESP. A retrospective cohort study was performed between 2002 and 2006, on 66 patients with serum and parasitological diagnosis of CD. Epidemiological, clinical, nutritional, and biochemical data were collected, including gender, age, skin color, smoking, alcoholism, physical activity, weight, stature, body mass index, abdominal circumference, glycemia, and lipid profile. Fifty-three percent were male and 47% female; 96% were white skinned. Mean age was 49.6±6.36 years. The predominant form was indeterminate in 71%; smoking and drinking were recorded in 23% and 17%, respectively. Sedentariness predominated in 83%, and 55% presented increased abdominal circumference. Most, 94%, were overweight or obese. The biochemical exams revealed hyperglycemia in 12% and dyslipidemia in 74%. These findings suggest that the Chagas population presents co-morbidities and risk factors for developing chronic non-transmissible diseases, including cardiovascular diseases, making CD evolution even worse.

    The present study had three objectives: (a) to characterize the functional capacity of patients with PD, (b) to assess the relationship between the physical fitness components of functional capacity with clinical characteristics and disease severity, and (c) to compare the physical fitness components of functional capacity with clinical characteristics according to disease severity. The study included 54 patients with idiopathic PD who were distributed into two groups according to PD severity: unilateral group (n=35); and bilateral group (n=19). All patients underwent psychiatric assessment by means of the Hoehn and Yahr (HY) staging of PD, the Unified Parkinson's Disease Rating Scale (UPDRS), the Hospital Anxiety and Depression Scale (HADS-A and HADS-D, respectively), and The Mini-Mental State Examination (MMSE). The physical fitness components of functional capacity were evaluated over a 2-day period, using recommendations by the American Alliance for Health, Physical Education, Recreation and Dance, and the Berg Balance Scale (BBS). Pearson correlation coefficients and multiple regressions were calculated to test the correlation between functional capacity and clinical characteristics, and to predict clinical scores from physical performance, respectively. Clinical variables and physical component data were compared between groups using analysis of variance to determine the effects of disease severity. Patients with advanced disease showed low levels of functional capacity. Interestingly, patients with good functional capacity in one of the physical fitness components also showed good capacities in the other components. Disease severity is a major factor affecting functional capacity and clinical characteristics. Medical providers should take disease severity into consideration when prescribing physical activity for PD patients, since the relationship between functional capacity and clinical characteristics is dependent on disease severity.

    Sexually transmitted diseases (STDs) are the first 10 causes of unpleased diseases in young adult women in the world. The concept of STDs includes a series of syndromes caused by pathogens that can be acquired by sexual intercourse or sexual activity.Adolescents and young adults are responsible for only 25% of the sexually active population and they represent almost 50% of all newly acquired STDs.In this way, we evaluated the epidemiological and clinical aspects of most relevant pathogens as Neisseria gonorrhoeae, Chlamydia trachomatis, Treponema pallidum, Haemophilus Ducreyi, Trichomonas vaginalis, herpes simplex virus, human papilloma virus (HPV) with the exception of hepatitis, and HIV infections for which we suggest specific guidelines.To attain this objective, we analyzed the results of epidemiological and clinical aspects of STDs through a review of the literature using MEDLINE and PubMed database for original articles published using the terms "sexual transmitted disease, epidemiology, diagnosis and therapy" from 2005 to 2014.

    This document presents the Movement Disorder Society Clinical Diagnostic Criteria for Parkinson's disease (PD). The Movement Disorder Society PD Criteria are intended for use in clinical research but also may be used to guide clinical diagnosis. The benchmark for these criteria is expert clinical diagnosis; the criteria aim to systematize the diagnostic process, to make it reproducible across centers and applicable by clinicians with less expertise in PD diagnosis. Although motor abnormalities remain central, increasing recognition has been given to nonmotor manifestations; these are incorporated into both the current criteria and particularly into separate criteria for prodromal PD. Similar to previous criteria, the Movement Disorder Society PD Criteria retain motor parkinsonism as the core feature of the disease, defined as bradykinesia plus rest tremor or rigidity. Explicit instructions for defining these cardinal features are included. After documentation of parkinsonism, determination of PD as the cause of parkinsonism relies on three categories of diagnostic features: absolute exclusion criteria (which rule out PD), red flags (which must be counterbalanced by additional supportive criteria to allow diagnosis of PD), and supportive criteria (positive features that increase confidence of the PD diagnosis). Two levels of certainty are delineated: clinically established PD (maximizing specificity at the expense of reduced sensitivity) and probable PD (which balances sensitivity and specificity). The Movement Disorder Society criteria retain elements proven valuable in previous criteria and omit aspects that are no longer justified, thereby encapsulating diagnosis according to current knowledge. As understanding of PD expands, the Movement Disorder Society criteria will need continuous revision to accommodate these advances. © 2015 International Parkinson and Movement Disorder Society.

Besides the symptomatic therapies, the increasing numbers of neurorestorative therapies have shown the potential therapeutic value of reversing the neurodegenerative process and improving the patient's quality of life. Currrently available novel clinical neurorestorative strategies include pharmacological managements (glial cell-line derived neurotrophic factor, selegiline, recombinant human erythropoietin, neuromodulation intervention (deep brain stimulation, repetitive transcranial magnetic stimulation, transcranial direct current stimulation, tissue and cell transplantation (fetal ventral mesencephalic tissue, sympathetic neurons, carotid body cells, bone marrow stromal cells, retinal pigment epithelium cells, gene therapy, and neurorehabilitative therapy. Herein, we briefly review the progress in this field and describe the neurorestorative mechanisms of the above-mentioned therapies for PD.

    Full Text Available Twenty patients with periodic paralysis were evaluated and the aspects studied included epidemiological data, clinical manifestations, ancillary tests, treatment and evolution. Sixteen patients had the hypokalemic form (5 familiar, 5 sporadic, 5 thyrotoxic and 1 secondary. No patient with the normokalemic form was detected. Predominance of men was found (14 patients, especially in the cases with hyperthyroidism (5 patients. No thyrotoxic patient was of oriental origin. Only 4 patients had the hyperkalemic form (3 familiar, 1 sporadic. Attacks of paralysis began during the first decade in the hyperkalemic form and up to the third decade in the hypokalemic. In both forms the attacks occurred preferentially in the morning with rest after exercise being the most important precipitating factor. Seventy five percent of the hyperkalemic patients referred brief attacks (<12 hours. Longer attacks were referred by 43% of the hypokalemic patients. The majority of the attacks manifested with a generalized weakness mainly in legs, and its frequency was variable. Creatinokinase was evaluated in 10 patients and 8 of them had levels that varied from 1,1 to 5 times normal. Electromyography was done in 6 patients and myotonic phenomenon was the only abnormality detected in 2 patients. Carbonic anhydrase inhibitors, especially acetazolamide, were used for prophylactic treatment in 9 pacients with good results in all. Although periodic paralysis may be considered a benign disease we found respiratory distress in 5 patients, permanent myopathy in 1, electrocardiographic abnormalities during crises in 4; death during paralysis occurred in 2. Therefore correct diagnosis and immediate treatment are crucial. This study shows that hyperthyroidism is an important cause of periodic paralysis in our country, even in non oriental patients. Hence endocrine investigation is mandatory since this kind of periodic paralysis will only be abated after return to the euthyroid state.

    Graves' disease is caused by stimulating autoantibodies against the thyrotropin receptor inducing uncontrolled overproduction of thyroid hormones. A Bridge Assay is presented for direct detection of these thyroid-stimulating immunoglobulins using thyrotropin receptor chimeras. A capture receptor, formed by replacing aa residues 261-370 of the human thyrotropin receptor with residues 261-329 from rat lutropin/choriogonadotropin receptor and fixed to microtiter plates, binds one arm of the autoantibody. The second arm bridges to the signal receptor constructed from thyrotropin receptor (aa 21-261) and secretory alkaline phosphatase (aa 1-519) inducing chemiluminescence. The working range of the assay is from 0.3 IU/l to 50 IU/l with a cutoff of 0.54 IU/l and functional sensitivity of 0.3 IU/l. Sensitivity and specificity are 99.8 and 99.1%, respectively, with a diagnostic accuracy of 0.998. The low grey zone is from 0.3-0.54 IU/l. The stimulatory character of the assayed antibodies is shown through a good correlation (r=0.7079, pGraves' disease, titers are increased in associated eye disease. In 3 hypothyroid patients with sera positive in the thyrotropin receptor competition assay and in the blocking bioassay, antibodies are not detected by the Bridge Assay, while the monoclonal blocking antibody K1-70 was detected. In Hashimoto disease thyrotropin receptor autoantibodies are detected in some patients, but not in goiter. This Bridge Assay delivers good diagnostic accuracy for identification of Graves' disease patients. Its high sensitivity may facilitate early detection of onset, remission, or recurrence of Graves' disease enabling timely adaption of the treatment.Human genes: TSHR, Homo sapiens, acc. no.

    The objective of this study was to further explore the effect of CAG repeat length on the rate of clinical progression in patients with Huntington's disease. The dataset included records for 569 subjects followed prospectively at the Baltimore Huntington's Disease Center. Participants were seen for a mean of 7.1 visits, with a mean follow-up of 8.2 years. Subjects were evaluated using the Quantified Neurologic Examination and its Motor Impairment subscale, the Mini-Mental State Examination, and the Huntington's disease Activities of Daily Living Scale. By itself, CAG repeat length showed a statistically significant but small effect on the progression of all clinical measures. Contrary to our previous expectations, controlling for age of onset increased the correlation between CAG repeat length and progression of all variables by 69% to 159%. Graphical models further supported the idea that individuals with smaller triplet expansions experience a more gradual decline. CAG repeat length becomes an important determinant of clinical prognosis when accounting for age of onset. This suggests that the aging process itself influences clinical outcomes in Huntington's disease. Inconsistent results in prior studies examining CAG repeat length and progression may indeed reflect a lack of age adjustment.

    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.

    Hartnup disease is a rare genetic disorder of amino acid transport associated with variable and intermittent clinical abnormalities. A family is described in which three siblings had an intermittently progressive neurological disease and two of the affected siblings had the Hartnup-pattern aminoaciduria. Neuropathological examination of one case showed severe diffuse atrophy, generalized neuronal loss in the cortex, and Purkinje cell loss in the cerebellum. In vivo and in vitro studies of intestinal amino acid transport in the surviving sibling indicated a partial defect in the transport of several neutral amino acids (tryptophan, alanine, serine, and methionine) with normal transport of other neutral amino acids (threonine, phenylalanine, histidine, tyrosine, and isoleucine). Transport of glycine, proline, hydroxyproline, and the basic amino acids appeared normal.

    Nutritional deficiencies are independent risk factors for adverse outcomes in patients with nervous system disease. Patients with nervous system disease can often become malnourished due to swallowing difficulties or unconsciousness. This malnourishment increases hospitalization duration; average total hospital cost; occurrence of infection, pressure ulcers, and other complications. These problems need to be addressed in the clinic. In this paper, we review the relevant literature, including studies on influencing factors, evaluations, indexes, and methods: Our aim is to understand the current status of malnutrition in patients with nervous system disease and reasons associated with nutritional deficiencies by using malnutrition evaluation methods to assess the risk of nutritional deficiencies in the early stages.

    Background Smoldering multiple myeloma (SMM) is an indolent disease stage, considered to represent the transition phase from the premalignant MGUS (Monoclonal Gammopathy of Undetermined Significance) state towards symptomatic multiple myeloma (MM). Even though this diagnosis provides an opportunity for early intervention, few treatment studies have been done and the current standard of care is observation until progression. BI-505, a monoclonal antibody directed against intercellular adhesion molecule 1 (ICAM-1) with promising anti-myeloma activity in preclinical trials, is a possible treatment approach for this patient category with potential to eliminate tumor cells with minimal long-term side effects. BI-505 was well tolerated in an earlier phase 1 trial. Methods and findings In this phase 2 trial the effects of BI-505 in patients with SMM were studied. Four patients were enrolled and three of them completed the first cycle of treatment defined as 5 doses of BI-505, a total of 43 mg/kg BW, over a 7-week period. In the three evaluable patients, BI-505 showed a benign safety profile. None of the patients achieved a response as defined per protocol. EudraCT number: 2012-004884-29. Conclusions The study was conducted to assess the efficacy, safety and pharmacodynamics of BI-505 in patients with SMM. BI-505 showed no clinically relevant efficacy on disease activity in these patients with SMM, even if well tolerated. Trial registration ClinicalTrials.gov Identifier: NCT01838369. PMID:28158311

    Recent studies have shown that early attention in patients with serious infections is associated with a better outcome. Assistance in intensive care units (ICU) can effectively provide this attention; hence patients should be admitted to the ICU as soon as possible, before clinical deterioration becomes irreversible. The objective of this article is to compile the recommendations for evaluating disease severity in patients with infections and describe the criteria for ICU admission, updating the criteria published 10 years ago. A literature review was carried out, compiling the opinions of experts from the Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica (SEIMC, Spanish Society for Infectious Diseases and Clinical Microbiology) and the Sociedad Española de Medicina Intensiva, Crítica y Unidades Coronarias (SEMICYUC, Spanish Society for Intensive Medicine, Critical Care and Coronary Units) as well as the working groups for infections in critically ill patients (GEIPC-SEIMC and GTEI-SEMICYUC). We describe the specific recommendations for ICU admission related to the most common infections affecting patients, who will potentially benefit from critical care. Assessment of the severity of the patient's condition to enable early intensive care is stressed.

    Full Text Available The annual incidence of adult-onset Still's disease (AOSD worldwide is 0.16 cases per 100,000 persons. Its leading symptoms are joint involvement, fever, skin rash, and neutrophilic leukocytosis in the absence of rheumatoid factor and anticyclic citrullinated peptide antibodies in serum and synovial fluid. In its initial stage, there may be monoarthritis more commonly of the wrist, hip, or knee. Then the lesion assumes the pattern of oligo- or polyarthritis.

    The relationship of minerals and trace elements with inflammatory bowel disease (IBD) is complex. Alterations in their metabolism can be induced by the diseases and their complications. To study the role of trace elements in IBD patients' serum zinc and copper and their related enzymes, including superoxide dismutase (SOD), activity were measured in patients with IBD patients as well as in healthy subjects. In addition, the correlation between serum trace element levels, albumin, total protein, urea level, copper/zinc ratio, and disease activity (DA) was determined in these subjects. Serum samples were obtained from 35 patients (19 ulcerative colitis (UC) and 16 Crohn's disease (CD)) in the active phase of the disease and 30 healthy control subjects. Serum levels of zinc, copper, SOD activity, albumin, total protein, and urea were measured. The results were compared between the two groups using independent Student's t test in statistical analysis. Serum levels of zinc, SOD activity, albumin, and total protein were significantly lower (P serum urea level was significantly higher in patients compared to controls. Copper concentrations did not differ between patients with IBD (mean ± SD, 58.8 ± 20.7 μg/d) and controls (55.57 ± 12.6 μg/d). Decreased levels of zinc and SOD activity are associated with increased inflammatory processes indicating inappropriate antioxidant system in patients with IBD. Additionally, lower levels of albumin and total protein with higher level of urea reflect metabolic problems in liver system.

    Disease recurrence following resective surgery for Crohn disease remains a challenging clinical problem, and more studies are needed to better define risk stratification and treatment recommendations in the postoperative setting. Endoscopy remains the gold standard for the assessment of postoperative disease recurrence, and all Crohn disease patients who undergo surgery should undergo ileocolonoscopy within 6 to 12 months of surgery. The degree of endoscopic recurrence in the neoterminal ileum during this procedure provides prognostic information regarding the severity of the future disease course. WCE, MRE, and SICUS are all promising noninvasive modalities to assess for postoperative Crohn disease activity. However, further studies are needed to better define scoring systems, operating characteristics and variability, and prognostic data for each of these modalities. In patients at risk for early disease recurrence, more aggressive prophylactic therapy should be considered, in hopes of delivering true “top-down” therapy that may offer maximum impact in altering the natural history of Crohn disease.

    The disease phenotype at diagnosis and the disease course of Crohn's disease (CD) and ulcerative colitis (UC) show remarkable heterogeneity across patients. 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 requires hospitalization or surgery/colectomy during follow-up. A change in the natural history of IBD with improved outcomes in parallel with tailored positioning of aggressive immunomodulator and biological therapy has been suspected according to the recently available literature. Therefore it is of major importance to refer IBD cases at risk for adverse disease outcomes as early during the disease course as possible. 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.

    Diverticulosis, diverticular disease and diverticulitis have come into focus again because new aspects concerning diagnosis, risk factors and treatment arose only recently which prompted a new Guideline released by the DGVS and DGAV summarising the current evidence. Along with the guideline's essentials for medical practice a diagnosis of diverticulitis is considered unsatisfactory unless a cross-sectional imaging method (either ultrasonography [US] or computed tomography [CT] ) has proven that the clinical findings and inflammation (CRP considered superior to WBC and temperature) are due to diverticular inflammation. For reasons of practicability and considering relevant legislation for radiation exposure protection, US is the primary - and usually effectual - diagnostic method of choice as it is equipotent to CT. While US offers better resolution and enables precise imaging exactly at the location of pain as well as reiterative application, the latter implies advantages in the case of a deep abscess or diverticulitis in difficult locations (e. g. the small pelvis). Clinical evidence and laboratory and imaging findings allow for distinguishing a large number of differential diagnoses and also form the basis of a new classification (classification of diverticular disease, CDD) which comprises all forms of diverticular disease, from diverticulosis to bleeding and to the different facettes of diverticulitis. This classification -which should be applied in any patient with the diagnosis of diverticular disease- is independent of specific diagnostic preferences and applicable both to conservative and operative treatment options. While the number of recurrent episodes is no longer a significant indicator for surgery in diverticulitis, severity and / or complications determine treatment options along with the patients preferences. According to first data, conservative treatment may waive antibiotics under certain circumstances, however they are indispensible in

    Homozygous or compound heterozygous mutations in the glucocerebrosidase gene cause Gaucher disease. Moreover, heterozygous glucocerebrosidase gene mutations represent the most common genetic risk factor for Parkinson's disease (PD) known so far. Substantia nigra (SN) hyperechogenicity, a sonographic feature thought to reflect iron accumulation, has been described in both PD and Gaucher disease patients. Here we studied how clinical, genetic, and brain sonographic findings relate to the occurrence of PD in Gaucher disease. Sixteen Gaucher disease patients, 12 PD patients, and 32 control subjects were enrolled. The glucocerebrosidase genotypes were identified by DNA sequencing. All subjects underwent transcranial ultrasound, and eight Gaucher disease patients additionally MRI for comparison with SN ultrasound findings. SN hyperechogenicity and reduced echogenicity of brainstem raphe were more frequent in Gaucher disease patients (62, 37 %) than in controls (12, 12 %; p Gaucher disease patients was unrelated to type or severity of glucocerebrosidase gene mutation, but correlated with iron-sensitive MRI-T2 hypointensity of SN pars compacta, and with age at start of enzyme replacement therapy. While none of the five Gaucher disease patients with signs of PD (definite PD, n = 4; early PD, n = 1) had severe glucocerebrosidase gene mutations known to cause neuronopathic Gaucher disease, all carried a N370S allele, previously reported to predict non-neuronopathic Gaucher disease. Hyposmia, higher non-motor symptoms score (constipation, depression, executive dysfunction), and SN hyperechogenicity were characteristic features of Gaucher disease-related PD. We conclude that the combined clinical, genetic, and transcranial sonographic assessment may improve the PD risk evaluation in Gaucher disease.

    Phosphorus is essential mineral to life, which has the multiple roles like postural maintenance or production of energy in the cells. Phosphate overload is harmful and compensatory mechanisms exist. Phosphate is abolished through kidneys and target organ of the compensatory mechanism is also kidneys. It is necessary to evaluate renal function and source of phosphate for estimating the cause of hyperphosphatemia. Acute hyperphosphatemia may cause severe acute kidney injury and avoidance of massive phosphate overload is needed. Chronic hyperphosphatemia have an impact on prognosis because the risk of cardiovascular event increases. Adequate restriction of phosphate intake and use of phosphate absorbent is needed for improvement of prognosis of patients with chronic kidney disease.

    MR urography (MRU) is an image diagnostic method which provides us with the image of urinary retention under non-invasive procedures. This time, MRU was conducted in the patients who were suspected to have urinary passage disorder, and its clinical usefulness was compared with that of drip infusion pyelography (DIP) or retrograde pyelography (RP). The study was conducted in 65 patients who were suspected to have obstructive uropathy based on the ultrasonographic findings. MRU was conducted by means of fast SE method to obtain heavy T2-weighted image. The urogram was reconstructed by means of MIP (maximum intensity projection) method. As imaging examinations, MRU, DIP and RP were conducted respectively in 65, 47 and 27 patients. Evaluation of clinical usefulness of MRU and its indications were conducted with respect to (1) the degree of urinary retention which is identifiable by MRU by (2) comparing performance of MRU and that of other image diagnostic methods based on the scores given to MRU and other methods according to the following scale: Urinary tract is not identifiable 0 point Urinary tract is slightly identifiable 1 point The obstructive region is almost clearly identifiable 2 points The lesion causative for obstruction is identifiable 3 points. 1) Mild urinary retention for which overall image of urinary tract was barely identifiable by DIP was identifiable by MRU. 2) In the comparison between DIP and MRU, 24 patients whose urinary tracts were totally unidentifiable by DIP was given was 2.4 points in the average for the identifiability of urinary retention by MRU. Conversely, only poor images were attainable by MRU in the patients whose urinary flow was clearly seen in DIP. The patients whose urinary flow was clearly seen in RP was give 1.9 points in the average for the identifiability of urinary retention by MRU, indicating that relatively poor images were attainable by MRU in those patients.

    Since the identification of the Huntington's disease (HD) gene, knowledge has accumulated about mechanisms directly or indirectly affected by the mutated Huntingtin protein. Transgenic and knock-in animal models of HD facilitate the preclinical evaluation of these targets. Several treatment approaches with varying, but growing, preclinical evidence have been translated into clinical trials. We review major landmarks in clinical development and report on the main clinical trials that are ongoing or have been recently completed. We also review clinical trial settings and designs that influence drug-development decisions, particularly given that HD is an orphan disease. In addition, we provide a critical analysis of the evolution of the methodology of HD clinical trials to identify trends toward new processes and endpoints. Biomarker studies, such as TRACK-HD and PREDICT-HD, have generated evidence for the potential usefulness of novel outcome measures for HD clinical trials, such as volumetric imaging, quantitative motor (Q-Motor) measures, and novel cognitive endpoints. All of these endpoints are currently applied in ongoing clinical trials, which will provide insight into their reliability, sensitivity, and validity, and their use may expedite proof-of-concept studies. We also outline the specific opportunities that could provide a framework for a successful avenue toward identifying and efficiently testing and translating novel mechanisms of action in the HD field.

    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.

    A dysregulated sympathetic nervous system is a major factor in the development and progression of cardiovascular disease; thus, understanding the mechanism and function of the sympathetic nervous system and appropriately regulating sympathetic activity to treat various cardiovascular diseases are crucial. Areas covered: This review focused on previous studies in managing hypertension, atrial fibrillation, coronary artery disease, heart failure, and perioperative management with sympathetic blockade. We reviewed both pharmacological and non-pharmacological management. Expert commentary: Chronic sympathetic nervous system activation is related to several cardiovascular diseases mediated by various pathways. Advancement in measuring sympathetic activity makes visualizing noninvasively and evaluating the activation level even in single fibers possible. Evidence suggests that sympathetic blockade still has a role in managing hypertension and controlling the heart rate in atrial fibrillation. For ischemic heart disease, beta-adrenergic receptor antagonists have been considered a milestone drug to control symptoms and prevent long-term adverse effects, although its clinical implication has become less potent in the era of successful revascularization. Owing to pathologic involvement of sympathetic nervous system activation in heart failure progression, sympathetic blockade has proved its value in improving the clinical course of patients with heart failure.

    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.

    We compared clinical and arteriographic features in 106 patients with symptomatic unilateral carotid territory occlusive disease to determine the frequency and distribution of occlusive arterial lesions in asymptomatic vessels. Among black patients who were predominantly from Chicago, young, and female, there were fewer transient ischemic attacks and myocardial infarcts, less claudication, and more asymptomatic lesions of the supraclinoid internal carotid artery, anterior cerebral artery stem, and the middle cerebral artery stem. Among white patients predominantly from New England, elderly, and male, there was more frequent and severe occlusive asymptomatic disease at extracranial carotid and vertebral artery sites. Knowledge of the distribution of asymptomatic lesions will help guide evaluation and treatment strategies for patients with occlusive cerebrovascular disease.

We compared mean age at symptom onset, age at PD diagnosis, and age at randomization between men and women using t-test statistics. Sex differences in clinical features were evaluated, including: symptoms at diagnosis (motor and symptoms at randomization (motor, non-motor, and daily functioning.1,741 participants were enrolled (62.5% male. No differences were detected in mean age at PD onset, age at PD diagnosis, age at randomization, motor symptoms, or daily functioning between men and women. Differences in non-motor symptoms were observed, with women demonstrating better performance compared to men on SCOPA-COG (Z = 5.064, p<0.0001 and Symbol Digit Modality measures (Z = 5.221, p<0.0001.Overall, men and women did not demonstrate differences in clinical motor features early in the course of PD. However, the differences observed in non-motor cognitive symptoms suggests further assessment of the influence of sex on non-motor symptoms in later stages of PD is warranted.

    2008-04-01

    Feline heartworm disease is caused by the filarial nematode Dirofilaria immitis, and is transmitted by mosquitoes in heartworm-endemic areas worldwide. While dogs are the definitive hosts for this parasite, cats can also be infected, and the overall prevalence in cats is between 5% and 10% of that in dogs in any given area. The spectrum of feline presentations varies from asymptomatic infections to chronic respiratory signs, sometimes accompanied by chronic vomiting to acute death with no premonitory signs. Ante-mortem diagnosis can be challenging and relies on a combination of tests, including antigen and antibody serology, thoracic radiography and echocardiography. As treatment with heartworm adulticidal drugs can be life-threatening and heartworm infection in cats is often self-limiting, infected cats are frequently managed with supportive treatment (corticosteroids, bronchodilators, and anti-emetics). Surgical removal of filariae using extraction devices may be considered in some acute cases where immediate curative treatment is necessary, but filarial breakage during the procedure may result in an acute fatal shock-like reaction. Necropsy findings are mainly pulmonary and include muscular hypertrophy of the pulmonary arteries and arterioles on histopathology. A number of safe and effective macrocytic lactone drugs are available for prophylaxis in cats. These drugs can kill a range of larval and adult life-cycle stage heartworms, which may be advantageous in cases of owner compliance failure or when heartworm infection status is undetermined at the time prophylaxis is commenced. An index of suspicion for feline heartworm disease is warranted in unprotected cats with respiratory signs, and perhaps chronic vomiting, in areas where canine heartworm disease is endemic. Many cats, once diagnosed and with appropriate supportive care and monitoring, will resolve their infection and be free of clinical signs.

    Full Text Available Usman H Malabu,1 Venkat N Vangaveti,1 Richard Lee Kennedy2 1School of Medicine and Dentistry, James Cook University, QLD, Australia; 2Department of Medicine, Deakin University, VIC, Australia Abstract: A hypoglycemia-induced fall is common in older persons with diabetes. The etiology of falls in this population is usually multifactorial, and includes microvascular and macrovascular complications and age-related comorbidities, with hypoglycemia being one of the major precipitating causes. In this review, we systematically searched the literature that was available up to March 31, 2014 from MEDLINE/PubMed, Embase, and Google Scholar using the following terms: hypoglycemia; insulin; diabetic complications; and falls in elderly. Hypoglycemia, defined as blood glucose <4.0 mmol/L (70 mg/dL requiring external assistance, occurs in one-third of elderly diabetics on glucose-lowering therapies. It represents a major barrier to the treatment of diabetes, particularly in the elderly population. Patients who experience hypoglycemia are at a high risk for adverse outcomes, including falls leading to bone fracture, seizures, cognitive dysfunction, and prolonged hospital stays. An increase in mortality has been observed in patients who experience any one of these events. Paradoxically, rational insulin therapy, dosed according to a patient's clinical status and the results of home blood glucose monitoring, so as to achieve and maintain recommended glycemic goals, can be an effective method for the prevention of hypoglycemia and falls in the elderly. Contingencies, such as clinician-directed hypoglycemia treatment protocols that guide the immediate treatment of hypoglycemia, help to limit both the duration and severity of the event. Older diabetic patients with or without underlying renal insufficiency or other severe illnesses represent groups that are at high risk for hypoglycemia-induced falls and, therefore, require lower insulin dosages.

    Neurodegenerative diseases constitute a major problem of public health that is associated with an increased risk of mortality and poor quality of life. Malnutrition is considered as a major problem that worsens the prognosis of patients suffering from neurodegenerative diseases. In this aspect, the present review is aimed to critically collect and summarize all the available existing clinical data regarding the clinical impact of nutritional assessment in neurodegenerative diseases, highlighting on the crucial role of nutritional status in disease progression and management. According to the currently available clinical data, the nutritional status of patients seems to play a very important role in the development and progression of neurodegenerative diseases. A correct nutritional evaluation of neurodegenerative disease patients and a right nutrition intervention is essential in monitoring their disease.

    Mutations in the glucocerebrosidase gene (GBA) are associated with Gaucher's disease, the most common lysosomal storage disorder. Parkinsonism is an established feature of Gaucher's disease and an increased frequency of mutations in GBA has been reported in several different ethnic series with sporadic Parkinson's disease. In this study, we evaluated the frequency of GBA mutations in British patients affected by Parkinson's disease. We utilized the DNA of 790 patients and 257 controls, matched for age and ethnicity, to screen for mutations within the GBA gene. Clinical data on all identified GBA mutation carriers was reviewed and analysed. Additionally, in all cases where brain material was available, a neuropathological evaluation was performed and compared to sporadic Parkinson's disease without GBA mutations. The frequency of GBA mutations among the British patients (33/790 = 4.18%) was significantly higher (P = 0.01; odds ratio = 3.7; 95% confidence interval = 1.12-12.14) when compared to the control group (3/257 = 1.17%). Fourteen different GBA mutations were identified, including three previously undescribed mutations, K7E, D443N and G193E. Pathological examination revealed widespread and abundant alpha-synuclein pathology in all 17 GBA mutation carriers, which were graded as Braak stage of 5-6, and had McKeith's limbic or diffuse neocortical Lewy body-type pathology. Diffuse neocortical Lewy body-type pathology tended to occur more frequently in the group with GBA mutations compared to matched Parkinson's disease controls. Clinical features comprised an early onset of the disease, the presence of hallucinations in 45% (14/31) and symptoms of cognitive decline or dementia in 48% (15/31) of patients. This study demonstrates that GBA mutations are found in British subjects at a higher frequency than any other known Parkinson's disease gene. This is the largest study to date on a non-Jewish patient sample with a detailed genotype/phenotype/pathological analyses

    Measurement instruments to assess user satisfaction with Clinical Information Systems (CIS) and with the implementation of CIS are needed as part of multi-faceted evaluation of CIS. Seven years of experience in developing measurement instruments to assess staff satisfaction with CIS preceded the development effort that created the Clinical Information System Evaluation Scale (CISIES). The scale was developed using precursors of the CISIES and it was guided by an expert panel. Following its construction the 37-item measurement instrument was piloted as part of the assessment of a Critical Care Clinical Information System implementation at a medical center in Florida, USA. Results indicated satisfaction with the implementation, although not strong, at the time of administration. The results of the CISIES administration were used by informaticians at the research site to plan and execute an intervention to improve satisfaction with the implementation. Re-administration of the CISIES at the site to evaluate the success of this intervention is planned. The CISIES was found to be a useful instrument, easy to administer, acceptable to respondents, easy to score and understandable by non-researcher at the study site. Early indications are that it will be useful in the formative and summative evaluation of CIS implementations.

    The focus of this study was on the development and field-testing of a set of behaviorally anchored rating scales for evaluating the clinical performance of dietetic students. The scales emphasized the application of skills and knowledge. A variation of the Smith-Kendall technique was used to develop the scales. The 42 participants involved in instrument development included dietetic students, didactic and clinical instructors, and dietetic practitioners. The completed instrument contained 8 dimension statements and 70 behavioral anchors. The instrument was field-tested in 16 clinical rotations within 8 dietetic education programs. Evaluators not only rated student performance but also critiqued the format and content of the scales. The mid-to-upper portions of each scale were used most frequently, and little score variation within or across programs was noted. The scales were deemed appropriate for formative evaluation; however, some evaluators who had to grade students' performance expressed a desire for performance standards defined in terms of grades. Because the process used to develop the instrument facilitated the articulation of performance criteria, it is recommended as a practical approach to setting performance standards.

    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

    Melasma is one of the most frequently acquired hyperpigmentation disorders clinically characterized by symmetrical brown patches on sun-exposed areas. To date, few studies have been conducted about the relationship between thyroid autoimmun-ity and melasma. To evaluate the thyroid dysfunction and autoimmunity in nonpregnant women with melasma. A total of 70 women with melasma and 70 age-matched healthy women with no history of melasma were enrolled in the study. We studied the thyroid hormone profile in both groups. The statistical analysis was performed using SPSS software. Patients with melasma had 18.5% frequency of thyroid disorders, and 15.7% had positive anti-TPO, while subjects from the control group had a 4.3% frequency of thyroid abnormalities, and only 5.7% had positive anti-TPO. There was a significantly higher prevalence of thyroid dysfunction in women with melasma compared with control group (P = 0.008). This study suggests that there is a relationship between thyroid autoimmunity and melasma. However, to make recommendations on screening for thyroid disease in patients with melasma, future research of good methodological quality is needed.

    Systemic autoinflammatory diseases are a group of inherited disorders of the innate immune system characterized by seemingly unprovoked inflammation recurring at variable intervals and involving skin, serosal membranes, joints, and gastrointestinal apparatus, with reactive amyloidosis as a possible severe long-term complication. Recent advances in genetics and molecular biology have improved our understanding of the pathogenesis of these diseases, including familial Mediterranean fever, mevalonate kinase deficiency syndrome, tumor necrosis factor receptor-associated periodic syndrome, cryopyrin-associated periodic syndromes, and hereditary pyogenic and granulomatous disorders: the vast majority of these conditions are related to the activation of the interleukin-1 pathway, which results in (or from?) a common unifying pathogenetic mechanism. Their diagnostic identification derives from the combination of clinical data, evaluation of acute phase reactants, clinical efficacy in response to specific drugs, and recognition of specific mutations in the relevant genes, although genetic tests may be unconstructive in some cases. This review will discuss clinical and laboratory clues useful for a diagnostic approach to systemic autoinflammatory diseases.

    Background An increasing incidence of Crohn' s disease has been found in China in recent years.Our study has been focused on evaluating the diversity of the clinical manifestations of Crohn' s disease in order to improve early diagnostic accuracy and therapeutic efficacy.Methods Thirty patients with active Crohn's disease were enrolled and their clinical data, including diagnostic and therapeutic results, were analyzed. Endoscopy combined with histological examination of biopsy specimens provided characteristic features of the disease. Transabdominal bowel sonography (TABS) was used for detecting intestinal complications. Nutritional supportive therapy was given to 20 subjects with active cases of the disease.Results Most patients were young adults with a higher proportion of females to males (ratio: 1.14:1). The disease affects any segment or a combination of segments along with the alimentary tract(from the mouth to the anus). In this study, the colon and small bowel were the major sites involved.Recurrent episodes of abdominal pain in the right lower quadrant and watery diarrhea were the most common symptoms. Granulomas were identifiable in nearly one-third (30.8%) of all biopsy specimens. In moderate cases of the disease, remission was achieved more quickly through the use of oral prednisone therapy than with SASP or 5-ASA. Beneficial effects on the host' s nutritional status were observed. Immunosuppressives were used on an individual basis and showed variable therapeutic effects. Sixteen patients had surgery due to intestinal obstruction or failure to respond to drug therapies. Rapid improvement after surgery was reported. Conclusion Endoscopy (with biopsy) and TABS were both crucial procedures for diagnosis. SASP(or 5-ASA) and prednisone were effective as inductive therapies. Azathioprine has demonstrable benefits after induction therapy with prednisone. Surgery, as an alternative treatment, provided another effective choice in selected patients.

    Polycystic Ovary Syndrome (PCOS) is recognized as the most common endocrine disorder of reproductive-aged women around the world. This document, produced by the collaboration of the American Association of Clinical Endocrinologists (AACE) and the Androgen Excess and PCOS Society (AES) aims to highlight the most important clinical issues confronting physicians and their patients with PCOS. It is a summary of current best practices in 2015. PCOS has been defined using various criteria, including menstrual irregularity, hyperandrogenism, and polycystic ovary morphology (PCOM). General agreement exists among specialty society guidelines that the diagnosis of PCOS must be based on the presence of at least two of the following three criteria: chronic anovulation, hyperandrogenism (clinical or biological) and polycystic ovaries. There is need for careful clinical assessment of women's history, physical examination, and laboratory evaluation, emphasizing the accuracy and validity of the methodology used for both biochemical measurements and ovarian imaging. Free testosterone (T) levels are more sensitive than the measurement of total T for establishing the existence of androgen excess and should be ideally determined through equilibrium dialysis techniques. Value of measuring levels of androgens other than T in patients with PCOS is relatively low. New ultrasound machines allow diagnosis of PCOM in patients having at least 25 small follicles (2 to 9 mm) in the whole ovary. Ovarian size at 10 mL remains the threshold between normal and increased ovary size. Serum 17-hydroxyprogesterone and anti-Müllerian hormone are useful for determining a diagnosis of PCOS. Correct diagnosis of PCOS impacts on the likelihood of associated metabolic and cardiovascular risks and leads to appropriate intervention, depending upon the woman's age, reproductive status, and her own concerns. The management of women with PCOS should include reproductive function, as well as the care of hirsutism

    Huntington's disease (HD) is centrally characterized by motor, neurocognitive and psychiatric symptoms, but impaired emotional decoding abilities have also been reported. However, more complex affective abilities are still to be explored, and particularly empathy, which is essential for social relations and is impaired in various psychiatric conditions. This study evaluates empathic abilities and social skills in pre-clinical and clinical HD, and explores the distinction between two empathy sub-components (emotional-cognitive). Thirty-six HD patients (17 pre-clinical) and 36 matched controls filled in the Empathy Quotient Scale, while controlling for psychopathological comorbidities. At the clinical stage of HD, no global empathy impairment was observed but rather a specific deficit for the cognitive sub-component, while emotional empathy was preserved. A deficit was also observed for social skills. Pre-clinical HD was not associated with any empathy deficit. Emotional deficits in clinical HD are thus not limited to basic emotion decoding but extend towards complex interpersonal abilities. The dissociation between impaired cognitive and preserved emotional empathy in clinical HD reinforces the proposal that empathy subtypes are sustained by distinct processes. Finally, these results underline the extent of distinct affective and social impairments in HD and the need to grasp them in clinical contexts.

    Clinical guidelines are documents to help professionals and patients select the best diagnostic or therapeutic option. Elaborating guidelines requires an efficient literature search and a critical evaluation of the articles found to select the most appropriate ones. After that, the recommendations are formulated and then must be externally evaluated before they can be disseminated. Even when the guidelines are very thorough and rigorous, it is important to know whether they fulfill all the methodological requisites before applying them. With this aim, various scales have been developed to critically appraise guidelines. Of these, the AGREE II instrument is currently the most widely used. This article explains the main steps in elaborating clinical guidelines and the main aspects that should be analyzed to know whether the guidelines are well written.

    The acquisition of competences (the set of knowledge, skills and attitudes required to perform a job to a professional level) is considered a fundamental part of medical training. Dermatology competences should include, in addition to effective clinical interviewing and detailed descriptions of skin lesions, appropriate management (diagnosis, differentiation, and treatment) of common skin disorders and tumors. Such competences can only be acquired during hospital clerkships. As a way of certifying these competences, we propose evaluating the different components as follows: knowledge, via clinical examinations or critical incident discussions; communication and certain instrumental skills, via structured workplace observation and scoring using a set of indicators; and attitudes, via joint evaluation by staff familiar with the student.

    Chronic disease management has been a rapidly growing entity in the 21st century as a strategy for managing chronic illnesses in large populations. However, experience has shown that disease management programs have not been able to demonstrate their financial value. The objectives of disease management programs are to create quality benchmarks, such as principles and guidelines, and to establish a uniform set of metrics and a standardized methodology for evaluating them. In order to illuminate the essence of disease management and its components, as well as the complexity and the problematic nature of performing economic calculations of their profitability and value, we collected data from several reports that dealt with the economic intervention of disease management programs. The disease management economic evaluation is composed of a series of steps, including the following major categories: data/information technology, information generation, assessment/recommendations, actionable customer plans, and program assessment/reassessment. We demonstrate the elements necessary for economic analysis. Disease management is one of the most innovative tools in the managed care environment and is still in the process of being defined. Therefore, objectives should include the creation of quality measures, such as principles and guidelines, and the establishment of a uniform set of metrics and a standardized methodology for evaluating them.

    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.

    Although several pharmacological agents have emerged as potential adjunctive therapies to a gluten-free diet for coeliac disease, there is currently no widely accepted measure of disease activity used in clinical trials. We conducted a systematic review of coeliac disease activity indices to evaluate their operating properties and potential as outcome measures in registration trials. MEDLINE, EMBASE and the Cochrane central library were searched from 1966 to 2015 for eligible studies in adult and/or paediatric patients with coeliac disease that included coeliac disease activity markers in their outcome measures. The operating characteristics of histological indices, patient-reported outcomes (PROs) and endoscopic indices were evaluated for content and construct validity, reliability, responsiveness and feasibility using guidelines proposed by the US Food and Drug Administration (FDA). Of 19 123 citations, 286 studies were eligible, including 24 randomised-controlled trials. Three of five PROs identified met most key evaluative criteria but only the Celiac Disease Symptom Diary (CDSD) and the Celiac Disease Patient-Reported Outcome (CeD PRO) have been approved by the FDA. All histological and endoscopic scores identified lacked content validity. Quantitative morphometric histological analysis had better reliability and responsiveness compared with qualitative scales. Endoscopic indices were infrequently used, and only one index demonstrated responsiveness to effective therapy. Current best evidence suggests that the CDSD and the CeD PRO are appropriate for use in the definition of primary end points in coeliac disease registration trials. Morphometric histology should be included as a key secondary or co-primary end point. Further work is needed to optimise end point configuration to inform efficient drug development.

    2017-01-01

    Abstract Background: Parkinson's disease (PD) is the second-most-common chronic and progressive neurodegenerative disease. The long-term use of levodopa leads to a loss of efficacy and to complications. Therefore, many patients with PD have turned to complementary therapies to help relieve their symptoms. Acupuncture is most commonly used as a complementary therapy in patients with PD. This paper presents a systematic review and meta-analysis of the effects of acupuncture for patients with PD. This study was performed to summarize and evaluate evidence regarding the effectiveness of acupuncture in the relief of PD symptoms. Methods: Seven databases, namely, MEDLINE, EMBASE, the Cochrane Library, the China National Knowledge Infrastructure [CNKI], and three Korean medical databases, were searched from their inception through August 2015 without language restrictions. Randomized controlled trials (RCTs) were included if they contained reports of acupuncture compared with no treatment and conventional treatment alone or acupuncture plus conventional treatment compared with conventional treatment alone for PD symptoms. Assessments were performed with the unified PD rating scales (UPDRS) I, II, III, and IV and the total score, the Webster scale, and effectiveness rating. Methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) scale and the Cochrane risk of bias (ROB). Results: In all, 982 potentially relevant articles were identified; 25 RCTs met our inclusion criterion, 19 of 25 RCTs were high-quality studies (i.e., a score of 6 or higher). The included RCTs showed favorable results for acupuncture plus conventional treatment compared with conventional treatment alone in the UPDRS II, III, and IV and the total score. Acupuncture was effective in relieving PD symptoms compared with no treatment and conventional treatment alone, and acupuncture plus conventional treatment had a more significant effect than conventional treatment alone

    This prospective study was designed to evaluate the potential contributions of high resolution ultrasonography (US) and Tc-99m scintigraphy in the routine diagnosis of thyroid disease. The diagnostic impacts of US and Tc-99m scintigraphy results in 177 patients visiting our thyroid clinic were assessed and scored according to the following criteria: when the information provided by either test supported, confirmed or changed the initial clinical diagnosis, they received scores of 2, 3 and 4 respectively, while score 1 was given when the test itself was useless for the differential diagnosis. US identified focal lesions that both palpation and scintigraphy had failed to detect in 14 (12.1%) of 116 patients with diffuse thyroid diseases, suggesting the necessity of Hashimoto's thyroiditis, adenoma, adenocarcinoma and adenomatous goiter, and vice versa in the diagnosis of hyperthyroid and euthyroid Graves's diseases. Thus, the advantages of US over scintigraphy for morphological evaluation were confirmed. US was particularly useful for the differential diagnosis of adenomatous goiter from Hashimoto's thyroiditis or a single nodular disease. In contrast, scintigraphy gave functional images, being especially helpful for the differential diagnosis of thyrotoxicosis. (author).

    Vertigo is one of the usual menopausal symptoms. We have often examined some women under the complaint of vertigo related with the menopause. We diagnosed each disease based on neuro-otological examinations and investigated the characteristics of menopausal-associated vertigo. We studied 413 women aged 40-59 years old who complained of vertigo. There were 73 women with menopause symptoms (14 women introduced from the gynecologist in our medical center, 18 women had undergone treatment at another female clinic, and 41 women visited an otorhinolaryngologist first) compared with 340 women without menopause symptoms. In the menopause group, 41 (56.2%) cases were diagnosed as having benign paroxysmal positional vertigo (BPPV), 13 (17.8%) cases had Meniere's disease, sudden deafness with vertigo accounted 2 cases, one was an acoustic tumor, and so on. The percentage of patients with BPPV was almost same ratio between the menopause group (56.2%) and the non-menopause group (52.9%). The percentage of patients with Meniere's disease was higher markedly in the menopausal group (17.8%). than the non-menopause group (9.7%). Menopausal symptoms are caused not only by hot flashes related to a lack of estrogen but also by psychological factors. The onset of Meniere's disease can also be influenced by psychological factors. As for the diagnosis of Meniere's disease, we supposed the reason for the higher percentage in the menopausal group was its relationship with psychological factors. We could diagnose and treat some menopausal women with vertigo. We believe that joint consultation with a gynecologist and otorhinolaryngologist would be necessary to ensure an optimum quality of life for such patients.

    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 (MMSE<10) in 6%. The mean interval between symptom onset and the initial primary care visit was 10.9±17.2 months (95% CI:9.9-11.8), and the interval between symptom onset and diagnosis with AD was 28.4±21.3 months. Results from the EACE show that most AD patients in our area have reached a moderate clinical stage by the time they are evaluated in a specialist clinic.

    2009-12-01

    Full Text Available Background and Design: The definition of emergent diseases includes potentially risky diseases that need urgent medical intervention. Diagnostic and therapeutic processes are managed mostly at ourpatient setting in dermatology. Therefore, it is unclear that which diseases are real emergencies and which patients apply urgently. There are a few studies assessing this topic. Our aim was to evaluate patients referred to our clinic urgently, and to review the concept of ‘‘real dermatologic emergency’’ by comparing dermatologic emergency patients and outpatients. Material and Method: A total of 800 patients (400 urgent patients, 400 outpatients were included. Demographic features, complaints, disease duration and severity, whether the disease occurs for the first time were questionned, application time and diagnosis were recorded. The opinions of patients and physicians were inquired about why they thought that the disease was emergent. Results: Most common skin diseases were acute urticaria-angioedema, contact dermatitis, and insect bite in emergency patients; acne vulgaris, verruca and tinea pedis in outpatients. Itching was more common in emergency patients. Emergency patients' complaints were more severe than those of outpatients. Patients who experience disease first time applied to emergency service more than others. Emergency patients had a shorter disease duration than outpatients. Patients and physicians revealed different reasons and criteria about the urgency of the diseases. 93.5% of patients and 49% of physicians thought that existing disease was emergent. Conclusion: Our data reveal that the concept of dermatologic emergency is unsettled. It changes according to socio-cultural, personal features and to the present health system. Determination of the main criteria of the definition of “dermatologic urgent”, and training of dermatologists, emergency centers’physicians and also of patients in this regard seem to be a necessity

  16. Update on the clinical management of Wilson’s disease

    2017-01-01

    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.

    Stoopler, Eric T; Sollecito, Thomas P

    2014-11-01

    Oral mucosal diseases encompass several common conditions that affect the general population. Some of these disorders present with signs and symptoms that are pathognomonic for the condition, whereas others present with similar features that can make clinical diagnosis difficult to achieve. It is important for physicians to have a clear understanding of these disorders to provide appropriate care to patients. This article reviews clinical aspects of common oral mucosal disorders, including candidiasis, herpes simplex viral infections, aphthous stomatitis, lichen planus, pemphigus vulgaris, and mucous membrane pemphigoid.

  19. Clinical Utility of Serologic Testing for Celiac Disease in Ontario

    Science.gov (United States)

    2010-01-01

    Executive Summary Objective of Analysis The objective of this evidence-based evaluation is to assess the accuracy of serologic tests in the diagnosis of celiac disease in subjects with symptoms consistent with this disease. Furthermore the impact of these tests in the diagnostic pathway of the disease and decision making was also evaluated. Celiac Disease Celiac disease is an autoimmune disease that develops in genetically predisposed individuals. The immunological response is triggered by ingestion of gluten, a protein that is present in wheat, rye, and barley. The treatment consists of strict lifelong adherence to a gluten-free diet (GFD). Patients with celiac disease may present with a myriad of symptoms such as diarrhea, abdominal pain, weight loss, iron deficiency anemia, dermatitis herpetiformis, among others. Serologic Testing in the Diagnosis Celiac Disease There are a number of serologic tests used in the diagnosis of celiac disease. Anti-gliadin antibody (AGA) Anti-endomysial antibody (EMA) Anti-tissue transglutaminase antibody (tTG) Anti-deamidated gliadin peptides antibodies (DGP) Serologic tests are automated with the exception of the EMA test, which is more time-consuming and operator-dependent than the other tests. For each serologic test, both immunoglobulin A (IgA) or G (IgG) can be measured, however, IgA measurement is the standard antibody measured in celiac disease. Diagnosis of Celiac Disease According to celiac disease guidelines, the diagnosis of celiac disease is established by small bowel biopsy. Serologic tests are used to initially detect and to support the diagnosis of celiac disease. A small bowel biopsy is indicated in individuals with a positive serologic test. In some cases an endoscopy and small bowel biopsy may be required even with a negative serologic test. The diagnosis of celiac disease must be performed on a gluten-containing diet since the small intestine abnormalities and the serologic antibody levels may resolve or improve

    Background. Frozen shoulder syndrome is a common musculoskeletal disease of idiopathic Parkinson's disease (PD) that causes long-term pain and physical disability. A better understanding of the associated factors can help identify PD patients who will require prevention to improve their quality of life. Methodology. This prospective study evaluated 60 shoulders of 30 PD patients. Correlation analysis was used to evaluate the relationships between clinical factors and shoulder sonography findings. Results. Frozen shoulder syndrome was found in 14 of 30 PD patients affecting 19 shoulders, including bilateral involvement in five and unilateral involvement in nine. There was a significant positive correlation between the parameters of sonography findings and frozen shoulder syndrome (i.e., thickness of bicipital effusion and tendon thickness of the subscapularis and supraspinatus) and mean ipsilateral Unified Parkinson's Disease Rating Scale (UPDRS) III and its subscores (tremor, rigidity, and bradykinesia scores). Conclusions. Higher ipsilateral UPDRS and subscores are associated with increased effusion around the biceps tendon, with increased tendon thickness of subscapularis and supraspinatus. Preventing frozen shoulder syndrome in the high-risk PD group is an important safety issue and highly relevant for their quality of life.

  8. Mapping gene associations in human mitochondria using clinical disease phenotypes.

    Directory of Open Access Journals (Sweden)

    2009-04-01

    Full Text Available Nuclear genes encode most mitochondrial proteins, and their mutations cause diverse and debilitating clinical disorders. To date, 1,200 of these mitochondrial genes have been recorded, while no standardized catalog exists of the associated clinical phenotypes. Such a catalog would be useful to develop methods to analyze human phenotypic data, to determine genotype-phenotype relations among many genes and diseases, and to support the clinical diagnosis of mitochondrial disorders. Here we establish a clinical phenotype catalog of 174 mitochondrial disease genes and study associations of diseases and genes. Phenotypic features such as clinical signs and symptoms were manually annotated from full-text medical articles and classified based on the hierarchical MeSH ontology. This classification of phenotypic features of each gene allowed for the comparison of diseases between different genes. In turn, we were then able to measure the phenotypic associations of disease genes for which we calculated a quantitative value that is based on their shared phenotypic features. The results showed that genes sharing more similar phenotypes have a stronger tendency for functional interactions, proving the usefulness of phenotype similarity values in disease gene network analysis. We then constructed a functional network of mitochondrial genes and discovered a higher connectivity for non-disease than for disease genes, and a tendency of disease genes to interact with each other. Utilizing these differences, we propose 168 candidate genes that resemble the characteristic interaction patterns of mitochondrial disease genes. Through their network associations, the candidates are further prioritized for the study of specific disorders such as optic neuropathies and Parkinson disease. Most mitochondrial disease phenotypes involve several clinical categories including neurologic, metabolic, and gastrointestinal disorders, which might indicate the effects of gene defects

    2011-01-01

    Executive Summary Objective The objective of this evidence-based analysis was to evaluate the clinical utility of serologic testing for celiac disease in asymptomatic individuals presenting with one of the non-gastrointestinal conditions evaluated in this report. The clinical utility was based on the effects of a gluten-free diet (GFD) on outcomes specific to each of these conditions. The prevalence of celiac disease in asymptomatic individuals and one of these non-gastrointestinal conditions was also evaluated. Clinical Need and Target Population Celiac Disease Celiac disease is an autoimmune disease characterized by a chronic inflammatory state of the proximal small bowel mucosa accompanied by structural and functional changes. Technology Under Evaluation Serologic Tests for Celiac Disease There are a number of serologic tests for celiac disease available. Serologic tests are automated with the exception of the anti-endomysial antibody test, which is more time-consuming and operator-dependent than the other tests. Research Questions What is the prevalence of asymptomatic celiac disease in patients presenting with one of the non-gastrointestinal conditions evaluated? What is the effect of the gluten-free diet on condition-specific outcomes in patients with asymptomatic celiac disease presenting with one of the non-gastrointestinal conditions evaluated? What is the clinical utility of serologic testing for celiac disease in asymptomatic patients presenting with one of the non-gastrointestinal conditions evaluated?

    Full Text Available Objective: In this study, we aimed to evaluate clinical and laboratory characteristics of patients with Kawasaki disease (KD in Konya region of Turkey. Methods: The hospital records of patients who were hospitalized with the diagnosis of KD in the Pediatrics Clinics of Konya Training and Research Hospital between May 2010 and June 2012 were reviewed retrospectively. Results: Seven cases were found to have the diagnosis of KD, two of whom were incomplete KD. Oropharynx changes were the most common (100% feature in our patients. Five (71% patients had bulbar conjunctivitis. Three (43% patients had erythema at the site of BCG inoculation. Adenopathy was present in all of our patients with the classical form. A desquamation was observed in one case at the seventh day of fever. No cardiac manifestation was seen. Elevated erythrocyte sedimentation rate and thrombocytosis were present in all patients. All of the patients were received intravenous immunoglobulin in the first ten days of the fever. Conclusion: KD should be considered as a possible diagnosis in any child presenting with prolonged fever. BCG reaction can be attributed as a diagnostic criterion for incomplete form of the disease especially in countries where BCG vaccination is routinely performed. Early treatment is essential to prevent cardiovascular complications.

    In the revised Danish medical specialist training increased focus has been placed on competences which are hard to evaluate such as communication skills. Mini-CEX seems promising as an evaluation tool. Our aim was to test: 1) whether mini-CEX was useable in the evaluation of communicative and cooperative skills and 2) whether mini-CEX would provide reproducible data. Twenty-one residents were evaluated by mini-CEX by trained observers. Seventeen residents had at least two observations within a short period of time and these data were used to estimate the mini-CEX reproducibility. In addition to the residents, the nurses who assisted them in the outpatient clinic answered a questionnaire regarding the mini-CEX satisfaction. Observations had a median duration of 20 minutes (10-60 minutes) and the overall median duration of feedback was 15 minutes (5-60 minutes). Time used for feedback was halved from the first to the following feedback sessions. No significant clinical differences were observed between the scorings performed by the residents themselves and the observers, or the nurses of the outpatient clinic and the observers. In general, the residents were satisfied with the mini-CEX evaluations. The mini-CEX is a promising tool for the evaluation of communicative and cooperative skills.

    2014-01-01

    Summary Ataxia-telangiectasia (A-T) is a rare autosomal recessive disorder caused by mutations in the ATM gene, resulting in faulty repair of breakages in double-stranded DNA. The clinical phenotype is complex, and is characterized by neurologic abnormalities, immunodeficiencies, susceptibility to malignancies, recurrent sinopulmonary infections, and cutaneous abnormalities. Lung disease is common in patients with A-T and often progresses with age and neurological decline. Diseases of the respiratory system cause significant morbidity and are a frequent cause of death in the A-T population. Lung disease in this population is thought to exhibit features of one or more of the following phenotypes: recurrent sinopulmonary infections with bronchiectasis, interstitial lung disease, and lung disease associated with neurological abnormalities. Here, we review available evidence and present expert opinion on the diagnosis, evaluation, and management of lung disease in A-T, as discussed in a recent multidisciplinary workshop. Although more data are emerging on this unique population, many recommendations are made based on similarities to other more well-studied diseases. Gaps in current knowledge and areas for future research in the field of pulmonary disease in A-T are also outlined. PMID:20583220

    Marburg virus outbreaks are sporadic, infrequent, brief, and relatively small in terms of numbers of subjects affected. In addition, outbreaks most likely will occur in remote regions where clinical trials are not feasible; therefore, definitive, well-controlled human efficacy studies to test the effectiveness of a drug or biologic product are not feasible. Healthy human volunteers cannot ethically be deliberately exposed to a lethal agent such as Marburg virus in order to test the efficacy of a therapy or preventive prior to licensure. When human efficacy studies are neither ethical nor feasible, the US Food and Drug Administration may grant marketing approval of a drug or biologic product under the 'Animal Rule,' through which demonstration of the efficacy of a product can be 'based on adequate and well-controlled animal efficacy studies when the results of those studies establish that the drug is reasonably likely to produce clinical benefit in humans.' This process requires that the pathogenic determinants of the disease in the animal model are similar to those that have been identified in humans. After reviewing primarily English-language, peer-reviewed journal articles, we here summarize the clinical manifestations of Marburg virus disease and the results of studies in NHP showing the characteristics and progression of the disease. We also include a detailed comparison of the characteristics of the human disease relative to those for NHP. This review reveals that the disease characteristics of Marburg virus disease are generally similar for humans and 3 NHP species: cynomolgus macaques (Macaca fascicularis), rhesus macaques (Macaca mulatta), and African green monkeys (Chlorocebus aethiops).

    Twenty-one patients who had undergone postradiation dental extraction were evaluated clinically. All patients had received irradiation for primary head and neck malignancies at doses ranging from 8 to 60 Gy (mean, 51.6 Gy). Time to dental extraction after irradiation ranged from 8 to 156 months (mean, 57.9 months). Of the 21 patients (80 teeth extracted, including 33 maxillary teeth and 47 mandibular teeth), one had delayed healing after wisdom tooth extraction due to postextraction irradiation. Thus, osteoradionecrosis after dental extraction did not develop. These results suggest that dental extraction after radiation is not contraindicated. To prevent complications, patients who have received radiation and require extractions should be cared for by oral and maxillofacial surgeons in close association with radiation oncologists.

    2016-07-01

    Celiac disease is induced by the consumption of gluten containing cereals (wheat, spelt, barley, rye). With a prevalence of ~ 1 %, it is the most common non-infectious chronic inflammatory intestinal disease worldwide. It manifests in all age groups, either classically with abdominal pain, diarrhoea and growth failure or weight loss, more commonly with indirect consequences of malabsorption, such as anaemia and osteoporosis, or with associated autoimmune diseases like type 1 diabetes, autoimmune thyroiditis or dermatitis herpetiformis. The pathogenesis of celiac disease is well explored. Gluten, the cereal storage protein, is not completely digested and reaches the intestinal mucosa where it activates inflammatory T cells, which cause atrophy of the resorptive villi. This T‑cell activation requires a genetic predisposition (the molecules HLA-DQ2 or -DQ8 on antigen-presenting immune cells). Moreover, the enzyme tissue transglutaminase (TG2) which is released in the mucosa increases the immunogenicity of the gluten peptides by a deamidation reaction. The test for serum antibodies to the autoantigen TG2 is one of the best diagnostic markers in medicine, which in combination with endoscopically obtained biopsies, secures the diagnosis of celiac disease. Despite these tools celiac disease is severely underdiagnosed, with 80-90 % of those affected being undetected. The untreated condition can lead to grave complications. These include the consequences of malabsorption, cancers (especially intestinal T‑cell lymphoma), and likely also the promotion of autoimmune diseases. The therapy of celiac disease, a strict gluten-free diet, is difficult to maintain and not always effective. Alternative, supporting pharmacological therapies are urgently needed and are currently in development.

    Full Text Available OBJECTIVE: To evaluate clinically, and with laboratory, tests, women with polycystic ovary syndrome (PCO. PATIENTS: One hundred and twelve women with PCO were studied. METHODS: The following data was recorded: Current age; age at menarche; menstrual irregularity, occurrence of similar cases in the family; fertility, obstetric history; body mass index (BMI; and presence of hirsutism. Serum measurements of follicle stimulating hormone (FSH, luteinizing hormone (LH, prolactin, free testosterone, and dehydroepiandrosterone sulfate were taken. RESULTS: All patients presented either oligomenorrhea (31 percent, periods of secondary amenorrhea (9 percent, or both alterations (60 percent. The majority of the patients were infertile (75.6 percent. The LH/FSH ratio was higher than 2:1 in 55 percent of the patients and higher than 3:1 in 26.2 percent. The ultrasonographic aspect of the ovaries was considered to be normal in 31 percent. CONCLUSION: The main clinical feature of the PCO is the irregularity of menses since menarche, and that the laboratory tests would be important to exclude other disorders such as hyperprolactinemia or hyperandrogenemia caused by late-onset congenital adrenal hyperplasia.

    The value of mass vaccination as a preventive measure for infectious diseases is one of the most important advances of modern Medicine. The impact on incidence of several infectious diseases, until recently responsible for significant morbidity and mortality at world level, is well proved in a series of high quality epidemiological studies. In this scientific review we aimed firstly to briefly resume the history of mass vaccination and its scientists, responsible for synthesis and marketing of these drugs. In second place we present a group of a few disease preventable by vaccines as well as the Portuguese National Vaccination Plan and its benefits. In third place we identified groups of subjects in which a well structured vaccination plan is particularly important, as well as the correspondent diseases to be covered by vaccination. Fourthly, we discussed the ethical considerations of vaccination, and its tensions between subject autonomy and society advantages in com pulsive programs. Fifthly, we analyzed clinical effectiveness of vaccines through the concept of herd immunity, clinical evaluation of immune response to vaccines and some examples of systematic reviews on three relevant diseases (influenza, meningococcal and pneumococcal infections). In sixth place we discussed vaccine safety presenting monitoring methods of vaccination risks, as well as discussing the public myths concerning vaccines. Finally we present a economic analysis of preventive vaccination with a review of some published literature on specific diseases. We conclude that mass vaccination is a efficacious preventive measure, as well as a economic rational choice, and that this public health intervention should be a pillar of a modern preventive system.

    The European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases convened a task force of experts in rheumatoid arthritis (RA) and clinical trial methodology to comment on the new draft 'Guideline on clinical investigation of medicinal products for the treatment of RA' released by the European Medicines Agency (EMA). Special emphasis was placed by the group on the development of new drugs for the treatment of early RA. In the absence of a clear definition of early RA, it was suggested that clinical investigations in this condition were conducted in disease-modifying antirheumatic drugs naïve patients with no more than 1 year disease duration. The expert group recommended using an appropriate improvement in disease activity (American College of Rheumatology (ACR) or Simplified/Clinical Disease Activity Index (SDAI/CDAI) response criteria) or low disease activity (by any score) as primary endpoints, with ACR/European League Against Rheumatism remission as a secondary endpoint. Finally, as compelling evidence showed that the Disease Acrivity Score using 28-joint counts (DAS28) might not provide a reliable definition of remission, or sometimes even low disease activity, the group suggested replacing DAS28 as a measurement instrument to evaluate disease activity in RA clinical trials. Proposed alternatives included SDAI, CDAI and Boolean criteria.

    Congenital heart disease(CHD) is the most common type of birth defect. Traditionally, a polygenic model defined by the interaction of multiple genes and environmental factors was hypothesized to account for different forms of CHD. It is now understood that the contribution of genetics to CHD extends beyond a single unified paradigm. For example, monogenic models and chromosomal abnormalities have been associated with various syndromic and non-syndromic forms of CHD. In such instances, genetic investigation and testing may potentially play an important role in clinical care. A family tree with a detailed phenotypic description serves as the initial screening tool to identify potentially inherited defects and to guide further genetic investigation. The selection of a genetic test is contingent upon the particular diagnostic hypothesis generated by clinical examination. Genetic investigation in CHD may carry the potential to improve prognosis by yielding valuable information with regards to personalized medical care, confidence in the clinical diagnosis, and/or targeted patient followup. Moreover, genetic assessment may serve as a tool to predict recurrence risk, define the pattern of inheritance within a family, and evaluate the need for further family screening. In some circumstances, prenatal or preimplantation genetic screening could identify fetuses or embryos at high risk for CHD. Although genetics may appear to constitute a highly specialized sector of cardiology, basic knowledge regarding inheritance patterns, recurrence risks, and available screening and diagnostic tools, including their strengths and limitations, could assist the treating physician in providing sound counsel.

    It goes back to 1932 when Dr. Burrill Bernard Crohn and co-workers published their landmark paper, describing regional ileitis as a disease entity. However, clinical trial research has been developing rather slowly in luminal Crohn's disease. It took until the early seventies before the first randomized clinical trial was set up by the National Co-operative Crohn's Disease Study (NCCDS) group. Although the efforts of this group triggered a first wave of clinical trials in Crohn's disease, the lack of guidelines for conducting a clinical trial in this research area resulted in a variety of study designs and much criticism. Besides having a rather small sample size and a short follow-up time, they were often characterized by vague and subjective assessment of disease activity and treatment response. Following the advent of a new and very potent drug class in the late nineties, the anti-TNF agents, investigators started to re-think their study protocols and the first guidelines were set up by the regulatory authorities. Over the last 15years, clinical trials in luminal Crohn's disease have been evolving significantly. Inclusion criteria have been shifting from clinical scores such as Crohn's Disease Activity Index (CDAI) to more objective disease activity parameters such as biomarkers (C-reactive protein and faecal calprotectin) and endoscopic lesions. Primary endpoints have been developing from clinical response to corticosteroid-free remission and more ambitious end-points such as mucosal healing. In this paper, we will give a historical overview on clinical trials in luminal Crohn's disease, before and within the biologic era, and provide insight into how they have shaped our current understanding of trial designs in Crohn's disease.

    Early identification of Alzheimer disease (AD) is important for clinical management and affords the opportunity to assess potential disease-modifying agents in clinical trials. To our knowledge, this is the first report of a randomized trial to prospectively enrich a study population with prodromal AD (PDAD) defined by cerebrospinal fluid (CSF) biomarker criteria and mild cognitive impairment (MCI) symptoms. To assess the safety of the γ-secretase inhibitor avagacestat in PDAD and to determine whether CSF biomarkers can identify this patient population prior to clinical diagnosis of dementia. A randomized, placebo-controlled phase 2 clinical trial with a parallel, untreated, nonrandomized observational cohort of CSF biomarker-negative participants was conducted May 26, 2009, to July 9, 2013, in a multicenter global population. Of 1358 outpatients screened, 263 met MCI and CSF biomarker criteria for randomization into the treatment phase. One hundred two observational cohort participants who met MCI criteria but were CSF biomarker-negative were observed during the same study period to evaluate biomarker assay sensitivity. Oral avagacestat or placebo daily. Safety and tolerability of avagacestat. Of the 263 participants in the treatment phase, 132 were randomized to avagacestat and 131 to placebo; an additional 102 participants were observed in an untreated observational cohort. Avagacestat was relatively well tolerated with low discontinuation rates (19.6%) at a dose of 50 mg/d, whereas the dose of 125 mg/d had higher discontinuation rates (43%), primarily attributable to gastrointestinal tract adverse events. Increases in nonmelanoma skin cancer and nonprogressive, reversible renal tubule effects were observed with avagacestat. Serious adverse event rates were higher with avagacestat (49 participants [37.1%]) vs placebo (31 [23.7%]), attributable to the higher incidence of nonmelanoma skin cancer. At 2 years, progression to dementia was more frequent in the PDAD

    There is a paucity of clinical trials informing specific questions faced by infectious diseases (ID) specialists. The ClinicalTrials.gov registry offers an opportunity to evaluate the ID clinical trials portfolio. We examined 40,970 interventional trials registered with ClinicalTrials.gov from 2007-2010, focusing on study conditions and interventions to identify ID-related trials. Relevance to ID was manually confirmed for each programmatically identified trial, yielding 3570 ID trials and 37,400 non-ID trials for analysis. The number of ID trials was similar to the number of trials identified as belonging to cardiovascular medicine (n = 3437) or mental health (n = 3695) specialties. Slightly over half of ID trials were treatment-oriented trials (53%, vs. 77% for non-ID trials) followed by prevention (38%, vs. 8% in non-ID trials). ID trials tended to be larger than those of other specialties, with a median enrollment of 125 subjects (interquartile range [IQR], 45-400) vs. 60 (IQR, 30-160) for non-ID trials. Most ID studies are randomized (73%) but nonblinded (56%). Industry was the funding source in 51% of ID trials vs. 10% that were primarily NIH-funded. HIV-AIDS trials constitute the largest subset of ID trials (n = 815 [23%]), followed by influenza vaccine (n = 375 [11%]), and hepatitis C (n = 339 [9%]) trials. Relative to U.S. and global mortality rates, HIV-AIDS and hepatitis C virus trials are over-represented, whereas lower respiratory tract infection trials are under-represented in this large sample of ID clinical trials. This work is the first to characterize ID clinical trials registered in ClinicalTrials.gov, providing a framework to discuss prioritization, methodology, and policy.

    Full Text Available Bowen Disease is squamous cell carcinoma in situ in which the basement membrane is intact on histopathology. Lesions are usually solitary but may be multiple in 10-20 percent of cases. It typically presents as an erythematous enlarging plaque having irregular borders with scaling and crusting. The lesions may be fissured or verrucous or, rarely, pigmented. Ulceration may occur and is often a sign that invasive disease is developing. The risk of progression of Bowen disease to invasive carcinoma is about 3%. Bowen disease is most commonly found in patients over 60 years old. Oher risk factors: include chronic sun exposure, immunosuppression, arsenic exposure and cutaneous human papillomavirus (HPV- 16, 18, 34 i 48 infection.The majority of cases of Bowen disease revealed a peculiar dermoscopic pattern characterized by glomerular vesselsProliferation of numerous atypical keratinocytes throughout the entire thickness of the epidermis with hyperkeratosis, mitotic figures, multinucleated cells and dyskeratotic cells, full thickness dysplasia of the squamous epithelum, disorderly maturation of the epidermis, parakeratosis and loss of granular layer.

    Pityriasis rosea (PR) is a common, acute, self-limiting inflammatory skin disease. It can easily be recognized with its typical clinical presentation. However, unusual clinic presentations can cause difficulty in diagnosis. Up to now, not many atypical forms are reported. To determine the clinical characteristics of patients with atypical pityriasis rosea. A total of 27 cases, diagnosed as atypical PR by clinical and/or histopathological examination and applied to the outpatient clinic of dermatology department between the years 2007 and 2015 were analyzed retrospectively. The ages of patients ranged from 2 to 59 years. Of these patients, 15 (55.6%) were male and 12 (44.4%) were female. The male-to-female ratio was 5-4. Five patients had papular, four patients had purpuric, three patients had vesicular, two patients had follicular, one patient had erythema multiforme-like and one patient had eczematous drug-induced atypical form of pityriasis rosea. There were 12 cases of localized, two cases of segmental pityriasis rosea. Four of the localized forms also had atypical morphology. Histopathological evaluation was required for diagnosis in 12 (44.4%) patients. PR can appear in many different uncommon forms. Localization and skin rush can be misleading and diagnosis can be compelling.

    Full Text Available Exposome is a critical dimension in the precision medicine paradigm. Effective representation of exposomics knowledge is instrumental to melding nongenetic factors into data analytics for clinical research. There is still limited work in (1 modeling exposome entities and relations with proper integration to mainstream ontologies and (2 systematically studying their presence in clinical context. Through selected ontological relations, we developed a template-driven approach to identifying exposome concepts from the Unified Medical Language System (UMLS. The derived concepts were evaluated in terms of literature coverage and the ability to assist in annotating clinical text. The generated semantic model represents rich domain knowledge about exposure events (454 pairs of relations between exposure and outcome. Additionally, a list of 5667 disorder concepts with microbial etiology was created for inferred pathogen exposures. The model consistently covered about 90% of PubMed literature on exposure-induced iatrogenic diseases over 10 years (2001–2010. The model contributed to the efficiency of exposome annotation in clinical text by filtering out 78% of irrelevant machine annotations. Analysis into 50 annotated discharge summaries helped advance our understanding of the exposome information in clinical text. This pilot study demonstrated feasibility of semiautomatically developing a useful semantic resource for exposomics.

    Coeliac disease is an intolerance to gluten that classically produces a chronic diarrhoea with a picture of malabsorption and a total villous atrophy. These elements regress completely in a sequential way under a prolonged strict gluten-free diet. The progress registered in the understanding of this affection depends on the individualization of the atypical forms (delayed isolated stature, constipation...) of asymptomatic forms thanks to the study of specific antibodies (anti-gliadin, anti-endomysium, and more recently anti-transglutaminase). The auto-immune nature of coeliac disease is well established. The diagnostic criteria are simplified allowing the commencement of a gluten-free diet which must be perfectly detailed. Finally, allergy to wheat flour merits individualization in the framework of coeliac disease (cf. article).

    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.

    The tools of modern molecular biology are evolving rapidly, resulting in vastly more efficient approaches to illuminating human genetic variations and their effects on common multifactorial disorders such as chronic kidney disease (CKD). Indeed, candidate gene association studies and genome-wide association studies (GWASs) have generated novel genetic variants in previously unrecognized biological pathways, highlighting disease mechanisms with a potential role in CKD etiology, morbidity and mortality. Nephrologists now need to find ways to make use of these advancements and meet the increasingly stringent requirements for valid study design, data handling and interpretation of genetic studies. Adding to our prior article in this journal, which introduced the basics of genotype-phenotype association studies in CKD, this second article focuses on how to ascertain robust and reproducible findings by applying adequate methodological and statistical approaches to genotype-phenotype studies in CKD populations. Moreover, this review will briefly discuss genotype-based risk prediction, pharmacotherapy, drug target identification and individualized treatment solutions, specifically highlighting potentially important findings in CKD patients. This increased knowledge will hopefully facilitate the exciting transition from conventional clinical medicine to gene-based medicine. However, before this can be accomplished, unsolved issues regarding the complex human genetic architecture as well technical and clinically oriented obstacles will have to be overcome. Additionally, new policies and standardized risk evaluations for genetic testing in the clinical setting will have to be established to guarantee that CKD patients are provided with high-quality genotype-guided counseling that will help to improve their poor outcomes.

    Full Text Available The past 30 years have seen rapid growth in the number of clinical trials in liver disease; due mostly to effective drug discovery programs by the pharmaceutical industry. The advantages associated with therapeutic trials in chronic liver disease, or any other disease for that matter, go far beyond potential benefit to the individual patient, other beneficiaries include the treating physician, the sponsoring agency and their investors, the institution/university and the general public. But there is always a downside to any experiment. The disadvantages and advantages of clinical trials in liver disease are the topics for this discussion.

    Full Text Available Objective: To investigate ankle tenosynovitis in rheumatoid arthritis patients, regarding its presence, the kind of tendon involved and the concordance between clinical and ultrasound findings. Methods: Twenty patients with rheumatoid arthritis and pain or swollen ankle joint were evaluated. Tendon involvement was evaluated with ultrasound imaging. The Health Assessment Questionnaire (HAQ was performed for disability evaluation. Age, sex, disease duration, and vocational activity levels were also obtained. The statistical analysis included Fisher’s exact test. The significance level was 0.05. Results: Tenosynovitis was found in 13 of 20 (65.0% patients in 19 joints, in which 6 were bilaterally (46.1% and unilateral in 7 (53.8%. Tibialis posterior tenosynovitis was seen in nine (45.0% patients, Achilles tenosynovitis in seven (35.0%, tibialis anterior tenosynovitis in three (15.0%, and peroneal tenosynovitis in three (15.0% patients. We found concordance between symptomatic ankle and ultrasonographic findings in 92.3% of the patients with tenosynovitis. Association between severe HAQ with tendon involvement was not found (p>0.05. Disease duration was not associated with tenosynovitis. Patients were predominantly older, female, with mean age around 50.8 years. The long disease duration of patients presented a mean of 11.4 years and, most of them, with no vocational activity (65.0%. Conclusions: The results indicate that ankle tenosynovitis is very common in rheumatoid arthritis patients, both unilateral and bilateral. Tibialis posterior was the most common tendon involvement found. Finally, we found concordance between the clinical and ultrasound findings in almost all rheumatoid arthritis patients with ankle tenosynovitis.

Currently, Butantan is one of the main public producers of vaccines, antivenoms, and antitoxins in Latin America. The partnership between Butantan and the National Institutes of Health (NIH) of the United Sates has been one of the longest and most successful partnerships in the development and manufacturing of new vaccines. Recently, Butantan Institute has developed and manufactured a lyophilized tetravalent live attenuated dengue vaccine with the four dengue viruses attenuated and licensed from the Laboratory of Infectious Diseases at The National Institutes of Allergy and Infectious Diseases (LID/NIAID/NIH). The objective of this paper is to describe the clinical evaluation strategies of a live attenuated tetravalent dengue vaccine (Butantan-DV) developed and manufactured by Butantan Institute. These clinical strategies will be used to evaluate the Butantan-DV Phase III trial to support the Butantan-DV licensure for protection against any symptomatic dengue caused by any serotype in people aged 2 to 59 years.

    An undetermined number of patients with temporomandibular joint (TMJ) symptoms have been treated with intra-articular disc implants composed of Teflon ethylene/propylene or Teflon polytetrafluoroethylene and aluminum oxide (Proplast-Teflon; Vitek, Houston, TX). These implants have shown the potential to fragment in situ resulting in nonbiodegradable particles that stimulate a giant cell reaction and lead to degeneration of local structures, pain, and limitation of mandibular opening. We examined the possible relationship between TMJ implants and persistent pain, responses to sensory stimuli, quality of life, and systemic immune dysfunction. This case series (32 patients) were referred from university-based orofacial pain centers and private practices from across the United States. Laboratory and clinical assessments evaluated orofacial pain symptoms, neurologic function, clinical signs and symptoms of rheumatologic disease, physical function, systemic measures of immune function, and behavioral measures. We found that TMJ implant patients appeared to have altered sensitivity to sensory stimuli, a higher number of tender points with a diagnosis of fibromyalgia, increased self-report of chemical sensitivity, higher psychologic distress and significantly lower functional ability. Systemic illness or autoimmune disease was not evident in this series of TMJ implant patients. Significant problems were noted on clinical assessment of TMJ implant patients. This is a US government work. There are no restrictions on its use.

    Full Text Available Abstract Background Observational studies have documented a potential protective effect of physical exercise in older adults who are at risk for developing Alzheimer's disease. The Fitness for the Ageing Brain II (FABS II study is a multicentre randomized controlled clinical trial (RCT aiming to determine whether physical activity reduces the rate of cognitive decline among individuals with Alzheimer's disease. This paper describes the background, objectives of the study, and an overview of the protocol including design, organization and data collection methods. Methods/Design The study will recruit 230 community-dwelling participants diagnosed with Alzheimer's disease. Participants will be randomly allocated to two treatment groups: usual care group or 24-week home-based program consisting of 150 minutes per week of tailored moderate physical activity. The primary outcome measure of the study is cognitive decline as measured by the change from baseline in the total score on the Alzheimer's disease Assessment Scale-Cognitive section. Secondary outcomes of interest include behavioral and psychological symptoms, quality of life, functional level, carer burden and physical function (strength, balance, endurance, physical activity. Primary endpoints will be measured at six and twelve months following the baseline assessment. Discussion This RCT will contribute evidence regarding the potential benefits of a systematic program of physical activity as an affordable and safe intervention for people with Alzheimer's disease. Further, if successful, physical activity in combination with usual care has the potential to alleviate the symptoms of Alzheimer's disease and improve its management and the quality of life of patients and their carers.

    Gunma Misonidazole Study Group has conducted an open clinical study to evaluate the radiosensitizing effects of misonidazole. Among the patients entered in this study, there were 119 patients with various local advanced or local recurrent radioresistant tumors. Of these, 29 patients had pulmonary cancer, 19 patients had glioblastoma, 10 patients had metastatic brain tumor, 31 patients had head and neck tumor, 16 patients had esophageal cancer and 14 patients had various other tumors. They were analyzed as to safety, effects on general condition besides radiosensitizing effects of misonidazole. The fractionation most often used was 1000 rad a week and a small dose of mis onidazole was given orally 4 hours before irradiation on treatment day s. The maximum total dose of misonidazole was 10 g/m/sup 2/. The plasma concentration of misonidazole was measured immediately before treatment. The mean value of plasma levels was 20.05 ..mu..g/ml. Accumulation of misonidazole in plasma was observed after its continuous administration. No severe irreversible neurotoxicites of misonidazole were observed, though 2 patients developed central nervous disorders and another 2 developed peripheral neuropathies. Radiosensitizing effect of misonidazole was not observed in 28% of the patients. But in the remaining 72%, there was a possibility of positive radiosensitizing effects of misonidazole. Prognosis was favarable in the patients with head and neck tumors on whom radiosensitizing effects of misonidazole were observed. Misonidazole had effects on initial tumor response to the treatment of pulmonary cancer, esophageal cancer and glioblastoma. Misonidazole is considered to be usefl cl inically, if it is combined with radiotherapy in the treatment of tumors that histologically have a great deal of anoxic components. But it should be emphasized that the development of more effective and less toxic radiosensitizer is necessary in clinical use.

    Doppler ultrasound is the most simple, inexpensive, accurate and versatile of the available noninvasive screening techniques to assess peripheral vascular diseases. The four fundamental components of peripheral arterial evaluation with this technique are assessment of blood velocity signal, measurement of resting ankle pressure, determination of segmental leg blood pressures, and measurement of ankle pressure response to exercise or reactive hyperemia. Plethysmography permits graphic recording of pulse-wave morphology, determination of digit blood pressure, and pulsatile responses to compression maneuvers. These techniques are useful in objectively quantifying peripheral arterial occlusive disease, predicting the results of operative therapy, monitoring the success of arterial reconstruction during surgery, and following the physiologic status of the patient after surgery.

    Objective To investigate the etiology, pathology, and mechanism of pathogenesis of Moyamoya disease.Methods A total of 15 human autopsies were analyzed. In addition, in order to create an animal model of the disease, 21 Japanese rabbits were divided randomly into two groups and subjected to injections of horse serum either intravenously or locally in the area of the sympathetic ganglia. Pathological and immunohistochemical characteristics were observed.Results The pathological features of the autopsies and the animal models both involved intima hyperplasia and stenosis or even occlusion of the lumen in the terminal ends of the internal carotid artery and the anterior and middle cerebral arteries. Disconnections or even breakages of the inner layer of the lumen were also observed, without an obvious inflammatory response. Hyperplasic smooth muscle cells of the medial membrane had extended inward through broken portions of the internal elastic lamina, with intima cell hyperplasia resulting in lumen stenosis. The hyperplastic vascular walls were positive for IgG and IgM.Conclusions The etiology of Moyamoya disease may involve allergic angiitis. A possible mechanism is that proximal portions of the circle of Willis first develop chronic stenosis or occlusion, leading to compensatory small vessel proliferation, which perforates into the cerebral parenchyma.

  15. Clinical pharmacokinetics of levodopa in parkinson's disease.

    1976-01-01

    Although levodopa has provided a major advance in the treatment of parkinsonism, its maximum benefits have not yet been realised, in part because of its complicated pharmacokinetics. This review summarises that available pharmacokinetic data involving levodopa, especially as it relates to therapeutic response of parkinsonian patients. A large number of factors, including protein intake, gastric emptying time, pyridoxine ingestion, and dopa decarboxylase activity, affect plasma levels of levodopa attained following oral administration of this drug. Other variables influence the rate of brain uptake of levodopa from the blood. Even so, plasma levodopa concentration correlates significantly with dosage size in a large parkinsonian population and also coincides with therapeutic response in many, but not all, patients. Therefore, in certain instances, valuable information may be derived by correlating clinical response with plasma levodopa concentration. Cerebrospinal fluid levels of homovanillic acid, a major metabolite of dopamine, may have some value in predicting clinical response to levodopa. This relationship, however, has not been firmly established. Concentration of homovanillic acid or levodopa in body fluids may also be closely related to certain adverse side-effects, including abnormal involuntary movements, gastric discomfort and psychiatric disturbances. Evidence indicates that a clearer understanding of levodopa pharmacokinetics may improve the clinical management of parkinsonism.

    The objectives were to determine the resistive index (RI) in normal cats and in cats with various renal diseases, and to evaluate the effect of age on RI. The subjects were cats that had ultrasonography (US) of the urinary tract and RI measurement at our centre between January 2003 and April 2014. Based on clinical evaluation, biochemical and haematological tests, urinalysis and US, the cats were classified as healthy or diseased. RI measurements were made from the interlobar or arcuate arteries. Data were analysed for differences between the right and the left kidney, the two sexes, different age groups in healthy cats, and between healthy and diseased cats. A total of 116 cats (68 males, 48 females) were included: 24 healthy and 92 diseased. In the healthy cats, RI (mean ± SD) differed significantly (P = 0.02) between the right kidney (0.54 ± 0.07) and the left kidney (0.59 ± 0.08). For the left kidney, RI was significantly higher in cats with chronic kidney disease (0.73 ± 0.12) and acute kidney injury (0.72 ± 0.08) (P = 0.0008). For the right kidney, RI was significantly higher in cats with chronic kidney disease (0.72 ± 0.11), acute kidney injury (0.74 ± 0.08), polycystic kidney disease (0.77 ± 0.11) and renal tumour (0.74 ± 0.001) (P cats, useful in the differential diagnosis of diffuse renal diseases. While it does not change with the age of the cat, ultrasonographers should be aware that RI may differ between the two kidneys. © ISFM and AAFP 2015.

    Clinical information models are formal specifications for representing the structure and semantics of the clinical content within electronic health record systems. This research aims to define, test, and validate evaluation metrics for software tools designed to support the processes associated with the definition, management, and implementation of these models. The proposed framework builds on previous research that focused on obtaining agreement on the essential requirements in this area. A set of 50 conformance criteria were defined based on the 20 functional requirements agreed by that consensus and applied to evaluate the currently available tools. Of the 11 initiative developing tools for clinical information modeling identified, 9 were evaluated according to their performance on the evaluation metrics. Results show that functionalities related to management of data types, specifications, metadata, and terminology or ontology bindings have a good level of adoption. Improvements can be made in other areas focused on information modeling and associated processes. Other criteria related to displaying semantic relationships between concepts and communication with terminology servers had low levels of adoption. The proposed evaluation metrics were successfully tested and validated against a representative sample of existing tools. The results identify the need to improve tool support for information modeling and software development processes, especially in those areas related to governance, clinician involvement, and optimizing the technical validation of testing processes. This research confirmed the potential of these evaluation metrics to support decision makers in identifying the most appropriate tool for their organization.

    Full Text Available Pompe disease is a rare inherited disease that belongs to lysosomal accumulation diseases and can be considered as cardiac glycogenosistype II, as well as a severe neuromuscular disease or metabolic myopathy. Physicians of different specialties very rarely identify this pathology, which is due to both its rarity and clinical and genetic polymorphism. Infantile Pompe disease is the severest form. It is characterized by a progressive pattern and a fatal outcome during the first year of life. The possibility of performing enzyme replacement therapy for this disease, which can improve the prognosis and quality of life of patients, makes the early diagnosis of Pompe disease urgent. The paper describes the clinical presentation of infantile Pompe disease and current methods for its diagnosis and treatment. The authors give their experience in diagnosing and treating infantile Pompe disease, by demonstrating 3 cases of the disease. The characteristics of each infant, which confirm the clinical and genetic variety of this pathology, are discussed.

    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.

    One hundred ninety-two subjects completed a clinical trial to determine the effects of seven dentifrice formulations on calculus inhibition. The double-blind study involved a ten-day control phase and a ten-day experimental phase. For the control phase, subjects were evaluated for calculus present, received a prophylaxis and had pre-weighed mylar strips attached to the lingual surfaces of the mandibular incisors to harvest mineral deposits. Subjects were then assigned the placebo dentifrice for unsupervised twice-daily use and were required to report once a day for a supervised mouthrinse using a 1:3 dilution of the dentrifice. The experimental phase was identical except that subjects were allocated the experimental dentifices using a stratified random assignment based on age, gender and the initial presence of calculus. Simple linear regression analyses of the dry and ash log weights obtained from the strips were performed. The results showed no statistically significant differences among the test products; however, two formulations containing zinc citrate showed some calculus inhibition-potential suggesting that further research and development of such products may be warranted.

    Full Text Available Introduction: The Parkinson disease can be among the multiple causes of alterations in the physical equilibrium. Accordingly, this study has the objective to evaluate Parkinson patients' physical equilibrium. Method: Potential study in which 12 Parkinson individuals were evaluated by way of tests of static and dynamic equilibrium, dynamic posturography and vectoelectronystagmograph. To compare the dynamic posturography results a group of gauged control was used. Results: Alterations in Romberg-Barré, Unterberger and Walk tests were found. The vestibular exam revealed 06 normal cases, 04 central vestibular syndrome and 02 cases of peripheral vestibular syndrome. In the dynamic posturography, an equilibrium alteration has been verified, when compared to the control group in all Sensorial Organization Tests, in average and in the utilization of vestibular system. Conclusion: Parkinson patients present a physical equilibrium alteration. The dynamic posturography was more sensitive to detect the equilibrium alterations than vectoelectronystagmograph.

    Imported parasitosis represents an increasingly frequent diagnostic challenge for microbiology laboratories. A surge in immigration and international travel has led to a rise in the number of imported cases of parasitosis, and this trend is expected to continue in the future. The present article addresses this challenge by reviewing recommended diagnostic approaches and tests. Currently, microscopy is always recommended when analysing blood samples for parasites. If malaria is suspected, rapid antigen testing (including at least HRP2 antigen) should also be performed. The work-up for suspected leishmaniasis should include serology, culture, and in selected cases detection of antigen in urine. In suspected Chagas disease, two different serological tests should be performed. PCR for blood protozoa is highly sensitive, although it cannot be used to rule out Chagas disease, since this condition may be present without parasitemia. Accurate diagnosis of intestinal amebiasis usually requires PCR or antigen detection tests. In helminthiasis, traditional microscopy may need to be complemented with other tests, such as agar plate culture for strongyloidiasis, Og4C3 antigen detection for bancroftian filariasis, and antibody detection test for filariasis and schistosomiasis.

    Faculty use numerous techniques to evaluate student nurses' clinical performance. The development of keen observational skills is crucial to evaluating students' performance, but this is only the first step. Fair student evaluations require the faculty member to recall incidents and draw sound conclusions about clinical performance events. There are various tools to assist the nurse educator in evaluating students' clinical performance. The authors describe one such tool, the anecdotal record, used by nursing faculty for clinical record keeping and evaluation. Guidelines for anecdotal record keeping and solutions to common management issues related to anecdotal record keeping are provided.

    The exact mechanism for the occurrence of sickle leg ulcers (SLUs) has not been fully explained, although, popular opinion supports a multifactorial etio-pathogenetic process. Leg ulceration in sickle cell is a chronic and debilitating condition which is difficult to treat and may worsen the psychosocial impact of this illness. This study aims to evaluate the laboratory and clinical correlates of SLUs. One hundred sixty-seven patients who had been diagnosed with sickle cell anemia (homozygous S) had their steady-state hemoglobin concentration (Hb), hematocrit, white cell count, platelet count, serum bilirubin, and aspartate transaminase (AST) as well as frequency of crisis per annum evaluated with respect to their relationship to the occurrence of leg ulcers. They were aged 6-53 years (mean age 24.3 years), and prevalence of leg ulcer was found to be 2.75 per 1000 (2.54 per 1000 in females and 2.83 per 1000 in males). The independent sample t-test showed a significant difference in the serum AST levels in those with SLU (p = 0.029), though a positive correlation did not exist. Other predictors of disease severity found to have positive relationship with each other were the AST and total serum bilirubin 0.207 (p = 0.012); Hb and age 0.130 (p = 0.035); Hb and white cell count -0.159 (p = 0.010), white cell count and age -0.113 (p = 0.018). SLUs do not occur in patients with severe disease in sickle cell. The clinical and laboratory indicators of severe sickle cell disease do not correlate positively with the occurrence of SLU. Serum AST may have a relationship with leg ulceration in these patients. Environmental factors most likely play a major part in the etiopathogenesis of leg ulcer and this may require further studies in different sociocultural settings.

    Although Spain is the European country with the highest Chagas disease burden, the country does not have a national control program of the disease. The purpose of this study is to evaluate the efficiency of several strategies for Chagas disease screening among Latin American residents living in Spain. The following screening strategies were evaluated: (1) non-screening; (2) screening of the Latin American pregnant women and their newborns; (3) screening also the relatives of the positive pregnant women; (4) screening also the relatives of the negative pregnant women. A cost-utility analysis was carried out to compare the four strategies from two perspectives, the societal and the Spanish National Health System (SNHS). A decision tree representing the clinical evolution of Chagas disease throughout patient's life was built. The strategies were compared through the incremental cost-utility ratio, using euros as cost measurement and quality-adjusted life years as utility measurement. A sensitivity analysis was performed to test the model parameters and their influence on the results. We found the "Non-screening" as the most expensive and less effective of the evaluated strategies, from both the societal and the SNHS perspectives. Among the screening evaluated strategies the most efficient was, from both perspectives, to extent the antenatal screening of the Latin American pregnant women and their newborns up to the relatives of the positive women. Several parameters influenced significantly on the sensitivity analyses, particularly the chronic treatment efficacy or the prevalence of Chagas disease. In conclusion, for the general Latin American immigrants living in Spain the most efficient would be to screen the Latin American mothers, their newborns and the close relatives of the mothers with a positive serology. However for higher prevalence immigrant population the most efficient intervention would be to extend the program to the close relatives of the negative

  17. Podometry: a critical evaluation of its use in Hansen's disease

    Directory of Open Access Journals (Sweden)

    Júlia Maria D'Andréa Greve

    Full Text Available The aim of this paper is to evaluate the effectiveness of podometry to measure the pressure developed over the feet and the value of these findings to help in the prevention of the plantar neuropathic ulcer in patients bearing Hansen's disease. We evaluated 13 patients with impaired plantar pain and touch sensations and 17 normal patients. All the patients were submitted to static evaluation using the podometer. The system employed was the "Midcapteur" commercial podometer composed of a platform for acquisition of analogic data capable of registering the segmental pressures applied to the feet. These data are read by a 386 IBM/PC compatible computer that registers the graphic patterns obtained from the pressures developed and also calculates the modes of pressure distribution in the four quadrants of the foot. These data obtained by means of static podometry were compared to the clinical evaluation of pain and touch sensation of the feet in hansenian patients. The results demonstrate that podometery is an efficient method for evaluating the pressure in impaired feet in Hansen's disease and is a progression of neuropathic ulcer; it is sensitive in the identification of the spots of increased pressure in anesthetic and anomalous areas, asymmetries and in correlating the presence of ulcers with increased pressure.

    The lack of consistent definitions and nomenclature across clinical trials of novel devices, drugs, or biologics poses a significant barrier to accrual of knowledge in and across peripheral artery disease therapies and technologies. Recognizing this problem, the Peripheral Academic Research Consortium, together with the U.S. Food and Drug Administration and the Japanese Pharmaceuticals and Medical Devices Agency, has developed a series of pragmatic consensus definitions for patients being treated for peripheral artery disease affecting the lower extremities. These consensus definitions include the clinical presentation, anatomic depiction, interventional outcomes, surrogate imaging and physiological follow-up, and clinical outcomes of patients with lower-extremity peripheral artery disease. Consistent application of these definitions in clinical trials evaluating novel revascularization technologies should result in more efficient regulatory evaluation and best practice guidelines to inform clinical decisions in patients with lower extremity peripheral artery disease.

    Science.gov (United States)

    2016-08-01

    Kawasaki disease is an acute self-limiting systemic vasculitis. It is the most common cause of acquired heart disease, with the risk of developing coronary artery aneurysms, myocardial infarction and sudden death. Diagnosis is based on the presence of fever in addition to other clinical criteria. The quarter of the Kawasaki disease patients have "incomplete" presentation. Treatment with intravenous immunoglobulin within ten days of fever onset improves clinical outcomes and reduces the incidence of coronary artery dilation to less than 5%. Non-responders to standard therapy have shown a successful response with the use of corticosteroids and/or biological agents. The long-term management must be delineated according to the degree of coronary involvement in a multidisciplinary manner. To facilitate the pediatrician's diagnosis, treatment and monitoring of Kawasaki disease, a group of experts from the Argentine Society of Pediatrics and the Argentine Society of Cardiology carried out a consensus to develop practical clinical guidelines.

    2011-12-01

    Full Text Available Background and Design: To determine the clinical and etiological features of inpatients with acute urticaria and angioedema and to assess the need for laboratory tests. Material and Methods: We recruited 105 patients with acute urticaria and angioedema who were admitted to our inpatient unit. The lesions and the characteristics of the patients were analyzed. Routine diagnostic tests including complete blood count, thyroid function tests, hepatitis panel, stool parasite, total IgE levels, cultures, erythrocyte sedimentation rate, C-reactive protein, anti-nuclear antibody, and posterior anterior lung X-ray were ordered. A psychiatric consultation was obtained, when needed. The results were analyzed with SPSS 15.0 statistical software.Results: Among 105 patients, 28 (26.7% had urticaria, 7 (6.7% had angioedema, and 70 (66.7% suffered from both urticaria and angioedema. The most common accompanying symptoms were itching (91.4% and burning (34.3%. The most common systemic symptoms were fatigue (15.2% and headache (12.4%. The lesions usually appeared in the evening hours (24.8%. Twenty-five patients were waking up due to itching during the night. Some lesions were associated with physical activities. Systemic diseases accompanied the lesions in 12 patients (11%. In terms of etiological factors, 33 patients (22.5% had infections. Food- related lesions were encountered in 14 (13% patients. Thirty patients (28.5% had history of medication use. Stress was detected in 37.1% of the patients; anxiety was diagnosed in 3% of patients. The stool was positive for parasites in 10 (9% patients. Conclusion: Acute urticaria is a benign disorder. Although the underlying cause of urticaria can not always be identified, infections and medications are the most common causes. A comprehensive and detailed history is very important to discover the underlying cause. The diagnostic tests should be ordered according to the patient’s history. Conducting diagnostic tests

    Antemortem studies pertaining to the manatee cardiovascular and cardiopulmonary systems are limited despite reports of cardiac disease in postmortem specimens. The objective of this project was to develop a technique for echocardiography in the Florida manatee (Trichechus manatus latirostris). Because of their unique anatomy, a ventral approach was employed by use of an echocardiography table designed specifically for this study. Fourteen clinically healthy, free-ranging and captive Florida manatees underwent echocardiography between the fall of 2011 and winter of 2012. Eight females and six males of various age categories were included in the study. Clear visualization of all valves and chambers was accomplished, and length and width measurements of the left atrium, peak aortic flow velocity, and ejection fraction percentage were calculated in most animals. Abnormalities observed during the study included atrioventricular regurgitation and severe right-atrial enlargement. Based on the results of this study, echocardiography in the Florida manatee is possible, which has both clinical and research implications in larger epidemiologic studies evaluating diseases of the cardiopulmonary and cardiovascular systems.

    Adequate nutrition plays an important role in the maintenance of cognitive function, particularly during aging. Malnutrition is amongst the risk factors for developing mild cognitive impairment (MCI) and Alzheimer's disease (AD). Epidemiological studies have associated deficiencies in some nutrients with a higher risk of cognitive dysfunction and/or AD. Cognitive decline in AD is correlated with synaptic loss and many of the components required to maintain optimal synaptic function are derived from dietary sources. As synapses are part of the neuronal membrane and are continuously being remodelled, the availability of sufficient levels of nutritional precursors (mainly uridine monophosphate, choline and omega-3 fatty acids) to make the phospholipids required to build neuronal membranes may have beneficial effects on synaptic degeneration in AD. In addition, B-vitamins, phospholipids and other micronutrients act as cofactors to enhance the supply of precursors required to make neuronal membranes and synapses. Despite this, no randomized controlled trial has hitherto provided evidence that any single nutrient has a beneficial effect on cognition or lowers the risk for AD. However, a multi-target approach using combinations of (micro)nutrients might have beneficial effects on cognitive function in neurodegenerative brain disorders like AD leading to synaptic degeneration. Here we review the clinical evidence for supplementation, based on a multi-target approach with a focus on key nutrients with a proposed role in synaptic dysfunction. Based on preclinical evidence, a nutrient mixture, Souvenaid(®) (Nutricia N.V., Zoetermeer, The Netherlands) was developed. Clinical trials with Souvenaid(®) have shown improved memory performance in patients with mild AD. Further clinical trials to evaluate the effects of nutritional intervention in MCI and early dementia due to AD are on-going.

    AIM: To evaluate the major clinical symptom, etiology, and diagnostic method in patients with primary small intestinal disease in order to improve the diagnosis.METHODS: A total of 309 cases with primary small intestinal disease were reviewed, and the major clinical symptoms,etiology, and diagnostic methods were analyzed.RESULTS: The major clinical symptoms included abdominal pain (71%), abdominal mass (14%), vomiting (10%),melaena (10%), and fever (9%). The most common disease were malignant tumor (40%). diverticulum (32%) and benign tumor (10%). Duodenal disease was involved in 36% of the patients with primary small intestinal diseases. The diagnostic rate for primary small intestinal diseases by double-contrast enteroclysis was 85.6%.CONCLUSION: Abdominal pain is the most common clinical symptom in patients with primary small intestinal disease.Malignant tumors are the most common diseases. Duodenum was the most common part involved in small intestine.Double-contrast enteroclysis was still the simplest and the most available examination method in diagnosis of primary small intestinal disease. However, more practical diagnostic method should be explored to improve the diagnostic accuracy.

  8. Clinical aspects of inflammation in Alzheimer's disease.

    Science.gov (United States)

    Rosenberg, Paul B

    2005-12-01

    In Alzheimer's disease (AD) there is increasing evidence that neurotoxicity is mediated by CNS inflammatory processes. These processes involve activation of microglia by amyloid-beta leading to release of pro-inflammatory cytokines including IL-1beta, IL-6, and TNF-alpha among others. Neurotoxic processes mediated by these cytokines may include direct neuronal death by enhancement of apoptosis, decreased synaptic function as evidence by inhibition of long-term potentiation, and inhibition of hippocampal neurogenesis. Central nervous system (CNS) inflammation may predate the development of senile plaques and neurofibrillary tangles in AD and may prove to be a more sensitive marker of prodromal AD. New developments in measuring CNS inflammation include measuring cytokine release by peripheral blood mononuclear cells and the development of PET markers of microglial activation. There is epidemiological evidence that circulating serum IL-6 is associated with poorer cognition. While epidemiological studies suggest a protective effect of NSAIDs against development of AD, controlled trials of NSAIDs to date have not shown any protective effect of drug. New anti-inflammatory agents for treating or preventing AD may include novel NSAIDs and opioid antagonists. These developments provide an alternative or potential adjunct to anti-amyloid therapies for AD.

    Traditional Chinese medicine (TCM) is a very practical subject, which has its unique theoretical system and clinical characteristics. In the course of clinical practice, the exact clinical efficacy is the key of existence and development. But the existing evaluation system is difficult to objectively evaluate the clinical efficacy of TCM. Therefore, how to objectively evaluate the clinical efficacy and get definitive evidence is the focus of the evaluation of clinical efficacy of TCM. Relative to modern medicine, TCM is more concerned about the changes of feelings and clinical symptoms of the patient in the course of the evolution of the disease. Soft targets mainly used for the evaluation of the clinical efficacy of symptoms and functional activity of the disease. The level in soft targets of processing technology is often used methods in clinical evaluation. But it has often produced the phenomenon which the results of the evaluation is mutual contradiction, which will ultimately affect the effect of evaluation of clinical efficacy of TCM. In order to better evaluate the clinical efficacy of TCM, in the process of adoption of soft targets, it clearly identify it's role, highlighting the characteristics of interventions on disease, and as much as possibly avoid the level in soft targets of processing technology to real assess clinical efficacy of TCM.

    2017-04-01

    Full Text Available Autosomal recessive polycystic kidney disease (ARPKD and other hepatorenal fibrocystic diseases (HRFD are relatively rare recessive disorders that constitute an important set of childhood nephropathies. Little is known about fundamental pathogenesis, and advances toward clinical trials will require well-characterized patient cohorts and the development of predictive and prognostic biomarkers. Such studies in rare diseases require greater collaboration than the efforts in common diseases where large patient repositories can be built at a single site. For the HRFD, clinical and translational research studies would be well served by centralized case accrual that coordinates collection of clinical data, biospecimens (DNA and tissues, and genetic information. As a part of the NIH-funded Hepatorenal Fibrocystic Disease Core Center, we have established a web-accessible portal to enroll patients with ARPKD and other HRFD and compile baseline and longitudinal clinical information in a REDCap-based clinical database. This central database is structured to collect clinical data from patients throughout the Americas (North, Central, and South. By using informatic analyses, we have defined the first data-driven estimates of ARPKD-related neonatal mortality, as well as the incidence and prevalence of this disease. These data indicate that while ARPKD is a rare disorder, there are hundreds of patients potentially available for deep clinical phenotyping in the United States alone. The centralization and sharing of clinical information and biomaterials from ARPKD and other HRFD patients hold the potential to accelerate progress in understanding disease pathways. Once the database is mature, the well-characterized patient cohorts will provide an important resource for developing clinical trials to evaluate new targeted therapeutic interventions in this spectrum of disorders.

    2014-12-01

    Network biology has become a powerful tool to dissect the molecular mechanisms triggering neurodegeneration. Recent developments in network biology have led to the discovery of disease-causing genes, diagnostic biomarkers, and therapeutic targets for several neurodegenerative diseases including Alzheimer's, Parkinson's, and Huntington's diseases. Network-based approaches have provided the molecular rationale for the relationship among cancer, diabetes, and neurodegenerative diseases, and have uncovered unexpected links between apparently unrelated diseases. Here, we summarize the recent advances in network biology to untangle the molecular underpinnings giving rise to the most prevalent neurodegenerative diseases. We propose that network analysis provides a feasible and practical tool for identifying biologically meaningful biomarkers and potential therapeutic targets for clinical intervention in neurodegenerative diseases.

    Sullivan Frank M

    2007-04-01

    Full Text Available Abstract Background Liver function tests (LFTs are routinely performed in primary care, and are often the gateway to further invasive and/or expensive investigations. Little is known of the consequences in people with an initial abnormal liver function (ALF test in primary care and with no obvious liver disease. Further investigations may be dangerous for the patient and expensive for Health Services. The aims of this study are to determine the natural history of abnormalities in LFTs before overt liver disease presents in the population and identify those who require minimal further investigations with the potential for reduction in NHS costs. Methods/Design A population-based retrospective cohort study will follow up all those who have had an incident liver function test (LFT in primary care to subsequent liver disease or mortality over a period of 15 years (approx. 2.3 million tests in 99,000 people. The study is set in Primary Care in the region of Tayside, Scotland (pop approx. 429,000 between 1989 and 2003. The target population consists of patients with no recorded clinical signs or symptoms of liver disease and registered with a GP. The health technologies being assessed are LFTs, viral and auto-antibody tests, ultrasound, CT, MRI and liver biopsy. The study will utilise the Epidemiology of Liver Disease In Tayside (ELDIT database to determine the outcomes of liver disease. These are based on hospital admission data (Scottish Morbidity Record 1, dispensed medication records, death certificates, and examination of medical records from Tayside hospitals. A sample of patients (n = 150 with recent initial ALF tests or invitation to biopsy will complete questionnaires to obtain quality of life data and anxiety measures. Cost-effectiveness and cost utility Markov model analyses will be performed from health service and patient perspectives using standard NHS costs. The findings will also be used to develop a computerised clinical decision

    Noninvasive approaches for assessment of liver histology include routine laboratory tests and radiological evaluation. The purpose of our study was to determine the utility of a simplified scoring system based on routinely evaluated ultrasound features for the evaluation of chronic liver disease and correlate it with the histological findings. For this cross-sectional analytical study the data was collected prospectively by nonprobability purposive sampling technique. The ultrasound variables/parameters and their assigned scoring system that was a modified version adopted from published literature were evaluated. Sensitivity, specificity, positive and negative predictive values of the liver morphological score and combined score of liver morphology and sizes was determined using stage and grade as reference standard. Our results show a high sensitivity and PPV of liver morphological sonographic evaluation for the staging and grading of CLD respectively thus supporting it as a screening diagnostic strategy. Of the three liver morphology variables, specificity of liver surface evaluation was highest for the stage of fibrosis and grade of inflammation. The simplified ultrasound scoring system evaluated in our study is clinically relevant and reproducible for differentiating patients with CLD with mild or no fibrosis from moderate to severe fibrosis.

The current study was designed to assess the prevalence of peripheral arterial disease (PAD) and its related risk factors in prediabetes patients. Methods: This was the case-control study in which 135 adults in three groups: Diabetes, prediabetes, and normal were studied. We evaluated the prevalence of PAD through the measurement of ankle-brachial index (ABI). All the patients were interviewed about demographic and medical data, including age, sex, disease duration, body mass index, hypertension (HTN), fasting blood glucose, hemoglobin A1C (HbA1C), lipid profile, and medication use. Results: The prevalence of PAD in diabetes patients was higher than the normal group (8.5%vs. 0.0%) (P < 0.05), but the differences between prediabetes compared with diabetes and normal group were not significant. The mean level of ABI in normal, prediabetes, and diabetes group was (1.11 ± 0.11), (1.09 ± 0.12), and (1.05 ± 0.03) respectively (P < 0.1). There were marginally significant differences of ABI observed between the normal group and the diabetes group. The observed differences between groups in the ABI were significant after adjusting the effects of age and sex (P < 0.05). There was an association observed between ABI and HbA1C in diabetes patients (r = 0.249, P < 0.01) and a significant association seen between PAD and HTN in the prediabetes group (P < 0.01). Conclusions: Peripheral arterial disease is common in asymptomatic diabetes and prediabetes patients. Management of hypertensive prediabetes patients and early detection of PAD in this group as well as in asymptomatic patients is important. PMID:25317291

    Parkinson’s disease (PD) is a chronic, neurodegenerative movement disorder that typically affects elderly patients. Swallowing disorders are highly prevalent in PD and can have grave consequences, including pneumonia, malnutrition, dehydration and mortality. Neurogenic dysphagia in PD can manifest with both overt clinical symptoms or silent dysphagia. Regardless, early diagnosis and objective follow-up of dysphagia in PD is crucial for timely and appropriate care for these patients. In this review, we provide a comprehensive summary of the electrophysiological methods that can be used to objectively evaluate dysphagia in PD. We discuss the electrophysiological abnormalities that can be observed in PD, their clinical correlates and the pathophysiology underlying these findings. PMID:25360228

    In the present study, clinical criteria used by Spanish nephrologists when approaching chronic kidney disease (CKD) in kidney recipients, as well as their level of maintenance and control of renal function, were evaluated. An epidemiological, observational, multicenter, nation-wide, prospective study was carried out, with a 6-month follow-up period. Three hundred and sixty-eight adult patients with stage3 kidney disease after a 24-month or longer post-transplantation follow-up period were included. Visits schedule included a retrospective visit, a baseline visit, an optional mid-term visit, and a final visit at month6. Mean time since kidney transplantation was 8.2±5.4years. Most common pre-transplant cardiovascular risk factors were high blood pressure (80.2%), followed by high cholesterol levels (61.7%). Serum creatinine levels showed a statistically significant decrease from baseline visit to 6-month visit (0.06±0.22; P<.0001), and glomerular filtration rate (GFR) reduction was -1.03±6.14 (P=0.0014). Significant independent prognostic factors for GFR worsening were: higher 24-hour proteinuria (OR=1.001 per mg; P=.020), longer time since transplantation (OR=1.009 per month; P=.017), and lower hemoglobin levels (OR=1.261 per g/dl; P=.038). Donor age also had some negative influence (OR=1.021 per year; P=.106). Biopsies were obtained in only 8% of kidney transplant recipients with stage 3 CKD with an intervention being carried out in 25.4% of cases. Secondary markers and factors resulting in CKD progression, particularly anemia, are still frequently uncontrolled after kidney transplantation. Only about 2% of patients benefit from a therapeutic intervention based on a biopsy. Clinical perception differs from objective measures, which results in an obvious clinical inertia regarding risk factor control in such patients. Copyright © 2015 The Authors.

    American College of Chest Physicians (CHEST) clinical practice guidelines on the evaluation of pulmonary nodules may have low adoption among clinicians in Asian countries. Unique patient characteristics of Asian patients affect the diagnostic evaluation of pulmonary nodules. The objective of these clinical practice guidelines was to adapt those of CHEST to provide consensus-based recommendations relevant to practitioners in Asia. A modified ADAPTE process was used by a multidisciplinary group of pulmonologists and thoracic surgeons in Asia. An initial panel meeting analyzed all CHEST recommendations to achieve consensus on recommendations and identify areas that required further investigation before consensus could be achieved. Revised recommendations were circulated to panel members for iterative review and redrafting to develop the final guidelines. Evaluation of pulmonary nodules in Asia broadly follows those of the CHEST guidelines with important caveats. Practitioners should be aware of the risk of lung cancer caused by high levels of indoor and outdoor air pollution, as well as the high incidence of adenocarcinoma in female nonsmokers. Furthermore, the high prevalence of granulomatous disease and other infectious causes of pulmonary nodules need to be considered. Therefore, diagnostic risk calculators developed in non-Asian patients may not be applicable. Overall, longer surveillance of nodules than those recommended by CHEST should be considered. TB in Asia favors lesser reliance on PET scanning and greater use of nonsurgical biopsy over surgical diagnosis or surveillance. Practitioners in Asia are encouraged to use these adapted consensus guidelines to facilitate consistent evaluation of pulmonary nodules. Copyright © 2016 American College of Chest Physicians.

    This paper applies co-occurrence statistics to discover disease-finding associations in a clinical data warehouse. We used two methods, chi2 statistics and the proportion confidence interval (PCI) method, to measure the dependence of pairs of diseases and findings, and then used heuristic cutoff values for association selection. An intrinsic evaluation showed that 94 percent of disease-finding associations obtained by chi2 statistics and 76.8 percent obtained by the PCI method were true associations. The selected associations were used to construct knowledge bases of disease-finding relations (KB-chi2, KB-PCI). An extrinsic evaluation showed that both KB-chi2 and KB-PCI could assist in eliminating clinically non-informative and redundant findings from problem lists generated by our automated problem list summarization system.

    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.

    Full Text Available CONTEXT AND OBJECTIVES:Anemia is the most frequent extraintestinal complication of inflammatory bowel disease. This study aimed to: 1 determine the prevalence of anemia among patients with inflammatory bowel disease; 2 investigate whether routine laboratory markers are useful for diagnosing anemia; and 3 evaluate whether any association exists between anemia and clinical/laboratory variables.DESIGN AND SETTING:Cross-sectional at a federal university.METHODS:44 outpatients with Crohn's disease and 55 with ulcerative colitis were evaluated. Clinical variables (disease activity index, location of disease and pharmacological treatment and laboratory variables (blood count, iron laboratory, vitamin B12 and folic acid were investigated.RESULTS:Anemia and/or iron laboratory disorders were present in 75% of the patients with Crohn's disease and in 78.2% with ulcerative colitis. Anemia was observed in 20.5% of the patients with Crohn's disease and in 23.6% with ulcerative colitis. Iron-deficiency anemia was highly prevalent in patients with Crohn's disease (69.6% and ulcerative colitis (76.7%. Anemia of chronic disease in combination with iron deficiency anemia was present in 3% of the patients with Crohn's disease and in 7% of the patients with ulcerative colitis. There was no association between anemia and disease location. In ulcerative colitis, anemia was associated with the disease activity index.CONCLUSIONS:Most patients present iron laboratory disorders, with or without anemia, mainly due to iron deficiency. The differential diagnosis between the two most prevalent types of anemia was made based on clinical data and routine laboratory tests. In ulcerative colitis, anemia was associated with the disease activity index.

    Human citomegalovirus (CMV) is a beta-herpesvirus able to establish lifelong persistent infections which usually remain asymptomatic. However, severe diseases may develop in immunocompromised subjects (e.g., AIDS patients and transplant recipients) and if acquired in utero. Circulating CMV clinical strains display genetic polymorphisms in multiple genes, which may be implicated in CMV-induced immunopathogenesis, as well as strain-specific tissue-tropism, viral spread in the host cells and virulence, finally determining the wide spectrum of clinical manifestations of CMV disease. Current literature report a number of studies regarding the main CMV polymorphic genes (UL55-gB, UL144, UL73-gN, UL74-gO), their diagnostic and therapeutic impact, their potential clinical relevance as prognostic markers. This paper aims to critically analyse the results of these studies and evaluate the linkage of strain-specific genotypes with clinical manifestations of CMV disease and their perspective implications.

    The role of biomarkers in clinical research was recently highlighted in the new criteria for the diagnosis of Alzheimer's disease. Cerebro-spinal fluid (CSF) biomarkers (total Tau protein, threonine 181 phosphorylated Tau protein and amyloid Aβ1-42 peptide) are associated with cerebral neuropathological lesions observed in Alzheimer's disease (neuronal death, neurofibrillary tangle with abnormal Tau deposits and amyloid plaque). Aβ1-40 amyloid peptide dosage helps to interpret Aβ1-42 results. As suggested in the latest international criteria and the French HAS (Haute Autorité de santé) recommendations, using theses CSF biomarkers should not be systematic but sometimes could be performed to improve confidence about the diagnostic of Alzheimer's disease in young subjects or in complex clinical situations. Future biomarkers actually in development will additionally help in diagnostic process (differential diagnosis) and in prognostic evaluation of neurodegenerative diseases.

    Gaucher disease (GD) is a lysosomal storage disorder characterized by accumulation of glucosylceramide in macrophages, so-called Gaucher cells, as a result of a deficiency of the lysosomal enzyme glucocerebrosidase. Bone complications are an important cause of morbidity of GD and are thought to result from imbalance in bone remodeling. Bone manifestations among GD patients demonstrate a large variation including increased osteoclastic bone resorption, low bone formation and osteonecrosis. The purpose of the current case series is to describe the histological features observed in undecalcified bone samples, obtained from three GD patients, and evaluate the relationship with clinical features in these patients. Bone fragments were obtained from three adult type 1 GD patients with variable degrees of bone disease during orthopedic surgery. Specimens were embedded without prior decalcification in methylmethacrylate and prepared for histology according to standardized laboratory procedures. Histology revealed a heterogeneous pattern of bone involvement. High cellularity of bone marrow, abundant presence of Gaucher cells (GCs) and high turnover were observed in a patient with a history of multiple bone complications, while minimal bone turnover and few GCs were detected in the mildest affected patient in this series. An intermediate picture with relatively low bone turnover and a substantial amount of Gaucher cells was demonstrated in the third, moderately affected patient. No gross abnormalities in three biochemical markers of bone turnover (osteocalcin, N-terminal propeptide of type 1 procollagen and type 1 collagen C-terminal telopeptide) were noted. Plastic embedding and subsequent Goldner and TRAP staining offered a unique possibility to study bone histological findings in GD. Our data show that bone manifestations in GD may vary both clinically as well as histologically and bone disease in GD will likely require a personalized approach.

    The availability of mobile health apps for self-care continues to increase. While little evidence of their clinical impact has been published, there is general agreement among health authorities and authors that consumers' use of health apps assist in self-management and potentially clinical decision making. A consumer's sustained engagement with a health app is dependent on the usability and functionality of the app. While numerous studies have attempted to evaluate health apps, there is a paucity of published methods that adequately recognize client experiences in the academic evaluation of apps for chronic conditions. This paper reports (1) a protocol to shortlist health apps for academic evaluation, (2) synthesis of a checklist to screen health apps for quality and reliability, and (3) a proposed method to theoretically evaluate usability of health apps, with a view towards identifying one or more apps suitable for clinical assessment. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram was developed to guide the selection of the apps to be assessed. The screening checklist was thematically synthesized with reference to recurring constructs in published checklists and related materials for the assessment of health apps. The checklist was evaluated by the authors for face and construct validity. The proposed method for evaluation of health apps required the design of procedures for raters of apps, dummy data entry to test the apps, and analysis of raters' scores. The PRISMA flow diagram comprises 5 steps: filtering of duplicate apps; eliminating non-English apps; removing apps requiring purchase, filtering apps not updated within the past year; and separation of apps into their core functionality. The screening checklist to evaluate the selected apps was named the App Chronic Disease Checklist, and comprises 4 sections with 6 questions in each section. The validity check verified classification of, and ambiguity in, wording

    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.

    Pompe's disease is a metabolic myopathy caused by a deficiency of acid alpha-glucosidase (GAA), also called acid maltase, an enzyme that degrades lysosomal glycogen. The clinical presentation of Pompe's disease is variable with respect to the age of onset and rate of disease progression. Patients with onset of symptoms in early infancy (infantile-onset Pompe disease (IOPD)) typically exhibit rapidly progressive hypertrophic cardiomyopathy and marked muscle weakness. Most of them die within the first year of life from cardiac and/or respiratory failure. In the majority of cases of Pompe's disease, onset of symptoms occurs after infancy, ranging widely from the first to sixth decade of life (late-onset Pompe's disease or LOPD). Progression of the disease is relentless and patients eventually progress to loss of ambulation and death due to respiratory failure. The objective of this study was to characterize the clinical presentation of 6 patients (3 with EOPD and the other 3 with LOPD) of 5 families from the East of Algeria. All our patients were diagnosed as having Pompe's disease based on biochemical confirmations of GAA deficiency by dried blood spots (DBS) and GAA gene mutations were analyzed in all patients who consented (n = 4). Our results are similar to other ethnic groups. PMID:28265479

    Although serological tests are useful for identifying celiac disease, it is well established that a minority of celiacs are seronegative. To define the prevalence and features of seronegative compared to seropositive celiac disease, and to establish whether celiac disease is a common cause of seronegative villous atrophy. Starting from 810 celiac disease diagnoses, seronegative patients were retrospectively characterized for clinical, histological and laboratory findings. Of the 810 patients, fourteen fulfilled the diagnostic criteria for seronegative celiac disease based on antibody negativity, villous atrophy, HLA-DQ2/-DQ8 positivity and clinical/histological improvement after gluten free diet. Compared to seropositive, seronegative celiac disease showed a significantly higher median age at diagnosis and a higher prevalence of classical phenotype (i.e., malabsorption), autoimmune disorders and severe villous atrophy. The most frequent diagnosis in the 31 cases with seronegative flat mucosa was celiac disease (45%), whereas other diagnoses were Giardiasis (20%), common variable immunodeficiency (16%) and autoimmune enteropathy (10%). Although rare seronegative celiac disease can be regarded as the most frequent cause of seronegative villous atrophy being characterized by a high median age at diagnosis; a close association with malabsorption and flat mucosa; and a high prevalence of autoimmune disorders.

    2015-07-01

    This article reviews the current status of the Clinical Core of the Alzheimer's Disease Neuroimaging Initiative (ADNI), and summarizes planning for the next stage of the project. Clinical Core activities and plans were synthesized based on discussions among the Core leaders and external advisors. The longitudinal data in ADNI-2 provide natural history data on a clinical trials population and continue to inform refinement and standardization of assessments, models of trajectories, and clinical trial methods that have been extended into sporadic preclinical Alzheimer's disease (AD). Plans for the next phase of the ADNI project include maintaining longitudinal follow-up of the normal and mild cognitive impairment cohorts, augmenting specific clinical cohorts, and incorporating novel computerized cognitive assessments and patient-reported outcomes. A major hypothesis is that AD represents a gradually progressive disease that can be identified precisely in its long presymptomatic phase, during which intervention with potentially disease-modifying agents may be most useful.

    Neuromyelitis optica is an inflammatory and usually relapsing demyelinating autoimmune disease of the central nervous system that targets the optic nerves and spinal cord. Rituximab has been used for different neurological diseases that are probably immune-mediated or involving humoural immunity. The objective of this study is to evaluate the efficacy and safety of rituximab as treatment for neuromyelitis optica in a tertiary hospital. Retrospective study of patients with neuromyelitis optica treated with rituximab 1000mg on days 1 and 15, repeated every 6 to 8 months. We recorded EDSS score, relapse rate, overall condition, CD19+ count, presence of anti-NMO antibodies, and possible adverse reactions. Six patients were treated; all were women with a median age of 46 years (range, 38-58). Anti-NMO antibodies were detected in 3 patients (50%). Baseline EDSS was 4 (range 2.0-5.5). Two patients had previously been treated with an immunomodulatory drug. Median time from the first rituximab infusion to first relapse was 3.7 years (range 1.7-6.9). Two patients had infusion reactions after the first dose of rituximab. Four patients remained relapse-free and their EDSS score did not progress during rituximab treatment, one patient showed no clinical improvement, and one patient could not be evaluated. Rituximab can be considered an attractive therapeutic alternative for patients with neuromyelitis optica as there are no approved treatments for this disease. Further studies with rituximab are needed to establish the role of this drug in treating neuromyelitis optica. Copyright © 2013 Sociedad Española de Neurología. Published by Elsevier España, S.L.U.

    Full Text Available Thalassemia is the most prevalent genetic disorder in Iran and around the world and these patients need regular careful care. The present study reports results of routine examination of patients visited Thalassemia clinic of Tehran. Data about clinical and laboratory examinations of 413 Thalassemic were extracted and analyzed. The prevalence of heart complications, diabetes, growth retardation, delayed puberty and primary and secondary amenorrhea was 9%, 8%, 21.3%, 3.1% and 6.3%, respectively. 44% didn't have secondary sex characteristics. Splenectomy had been done for 67.2% of cases. HBsAg, HBsAb and HBcAb were positive in 1.9%, 57.4% and 43%, respectively. We concluded that blood transfusion standards in this clinic was acceptable, whereas because of poor knowledge, iron chelating is unfavorable.

    To assess clinical variables that may be useful in differentiating gynaecomastia from carcinoma and to analyse the contribution of mammography and ultrasound to the evaluation of male breast disease. All men who underwent mammography and/or ultrasound between 1993 and 2006 in our hospital were retrospectively evaluated. Clinical characteristics in patients with gynaecomastia and those with carcinoma were compared. Radiological findings were classified according to the BI-RADS (Breast Imaging Reporting and Data System) criteria. The diagnostic performance of physical examination, mammography and ultrasound was determined and compared. A total of 628 patients with 518 mammograms and 423 ultrasounds were reviewed. The final diagnoses were: 19 carcinomas, 526 gynaecomastias, 84 other benign conditions and 25 normal. There were statistically significant differences in age, bilateral involvement, clinical presentation and physical examination between patients with carcinoma and those with gynaecomastia. The diagnostic performance of physical examination was lower than that of mammography and ultrasound (p < 0.05 for specificity). Mammography was the most sensitive (94.7%) and ultrasound the most specific (95.3%) for detection of malignancy (p > 0.05). We propose an algorithm for the use of mammography and ultrasound in men. Mammography and ultrasound, with a negative predictive value close to 100%, make it possible to avoid very many unnecessary surgical procedures in men. (orig.)

    AIM: To evaluate cladribine [2-chlorodeoxyadenosine (2-CdA)] therapy in refractory celiac disease (RCD) Ⅱ. METHODS: An open-label cohort-study of RCD Ⅱ patients treated with 2-CdA was performed between 2000 and 2010. Survival rate, enteropathy associated T-cell lymphoma (EATL) occurrence, clinical course, and histological and immunological response rates were evaluated. RESULTS: Overall, 32 patients were included with a median follow-up of 31 mo. Eighteen patients responded well to 2-CdA. Patients responsive to 2-CdA had a statistically significant increased survival compared to those who were unresponsive. The overall 3- and 5-year survival was 83% in the responder and 63% and 22% in the non-responder group, respectively. The overall 2-year clinical, histological and immunological response rates were 81%, 47% and 41%, respectively. Progression into EATL was reported in 16%, all of these patients died. CONCLUSION: Treatment of RCD Ⅱ with 2-CdA holds promise, showing excellent clinical and histological response rates, and probably less frequent transition into EATL.

    The use of systemic and inhaled corticosteroids for COPD has increased appreciably over the past 20 years. Clearer indications for corticosteroid therapy in COPD are beginning to emerge as the results from large clinical trials become available. Systemic corticosteroids are only modestly effective for acute COPD exacerbations, increase the risk for hyperglycemia, and should be given for no more than 2 weeks. The efficacy of long-term systemic corticosteroid therapy has not been adequately evaluated in this patient population. If longer term use of systemic steroids in COPD should be found to be useful, this conclusion would have to be weighed against the risk for serious adverse effects. High doses of inhaled corticosteroids cause a small sustained increase of the FEV1 in patients with mild and moderately severe COPD, but they do not slow the rate of FEV1 decline. Based on analyses of secondary outcome, inhaled corticosteroids may improve the respiratory symptoms and decrease the number and severity of COPD exacerbations in patients with more advanced disease. Low doses of inhaled corticosteroids appear to be safe, but there is growing awareness that higher doses may not be so benign.

  3. BACE1 inhibitor drugs in clinical trials for Alzheimer's disease.

    2014-01-01

    β-site amyloid precursor protein cleaving enzyme 1 (BACE1) is the β-secretase enzyme required for the production of the neurotoxic β-amyloid (Aβ) peptide that is widely considered to have a crucial early role in the etiology of Alzheimer's disease (AD). As a result, BACE1 has emerged as a prime drug target for reducing the levels of Aβ in the AD brain, and the development of BACE1 inhibitors as therapeutic agents is being vigorously pursued. It has proven difficult for the pharmaceutical industry to design BACE1 inhibitor drugs that pass the blood-brain barrier, however this challenge has recently been met and BACE1 inhibitors are now in human clinical trials to test for safety and efficacy in AD patients and individuals with pre-symptomatic AD. Initial results suggest that some of these BACE1 inhibitor drugs are well tolerated, although others have dropped out because of toxicity and it is still too early to know whether any will be effective for the prevention or treatment of AD. Additionally, based on newly identified BACE1 substrates and phenotypes of mice that lack BACE1, concerns have emerged about potential mechanism-based side effects of BACE1 inhibitor drugs with chronic administration. It is hoped that a therapeutic window can be achieved that balances safety and efficacy. This review summarizes the current state of progress in the development of BACE1 inhibitor drugs and the evaluation of their therapeutic potential for AD.

    Neurological diseases are characterized by the complexity of care and by a constant and changing disability. More and more frequently, their impact on the clinical pathway remains unknown. Seven postgraduate rehabilitation students (Master coordination du handicap, université Pierre-et-Marie-Curie, Paris) reconstructed the clinical pathway of 123 patients with various neurological diseases: multiple sclerosis, Alzheimer disease, amyotrophic lateral sclerosis, spinal trauma, Parkinson disease and brain tumors. There was a significant correlation between disease duration and the number of specialists involved in care, the number of prescribed drugs and the number of short-term hospitalizations; there was no correlation with age. This result suggests that with time an increasing number of complications related to the initial neurological disease developed. Hospitalization in rehabilitation units was highly correlated with the degree of disability and also with the help received by the patients during the course of their disease. This result suggests that these hospitalizations were a direct consequence of burn out among relatives. General practitioners (GP) were highly involved only during the initial part of the pathway, and their involvement rapidly declined thereafter, suggesting a probable relation with the specificities and the complexity of care for neurological diseases which induces a progressive transfer of responsibilities from the GP to the hospital. Social care was always incomplete and occurred too late during the course of the disease. The feeling by the patients that their care pathway was chaotic was highly correlated with the quality of the information given to the patient at the time of the announcement of their disease. This study confirms that cares for neurological diseases is highly specific and that expert centers and coordination networks are in a key position to ensure an efficient care pathway.

  7. An evaluation of rheumatology practitioner outreach clinics: a qualitative study

    2012-01-01

    Background Services for Rheumatoid Arthritis (RA) have evolved with the development of independently led outreach Rheumatology Practitioner (RP) clinics in Primary Care (PC). Their clinical and cost effectiveness, compared with Secondary Care (SC) services, has not been assessed. The RECIPROCATE study aims to evaluate their clinical and cost effectiveness. This part of the study aimed to explore health professionals’ opinions of rheumatology outreach service. Methods Using a qualitative design, semi-structured interviews were conducted with GPs, practice nurses, hospital doctors and RPs, from one hospital and seven PC practices in Norfolk, to elicit their opinions of the service. The interviews were analysed using thematic analysis. Results All participants agreed the service was supportive and valuable providing high quality personalised care, disease management, social, and educational support. Advantages identified included convenience, continuity of care and proximity of services to home. RPs helped bridge the communication gap between PC and SC. Some participants suggested having a doctor alongside RPs. The service was considered to be cost effective for patients but there was uncertainty about cost effectiveness for service providers. Few disadvantages were identified the most recurring being the lack of other onsite services when needed. It was noted that more services could be provided by RPs such as prescribing and joint injections as well as playing a more active role in knowledge transfer to PC. Conclusions Professionals involved in the care of RA patients recognised the valuable role of the RP outreach clinics. This service can be further developed in rheumatology and the example can be replicated for other chronic conditions. PMID:22607063

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.

    Infantile-onset Pompe disease has a fatal prognosis in the short term unless it is diagnosed at an early stage and enzyme replacement therapy is not started as soon as possible. A group of specialists from different disciplines involved in this disease have reviewed the current scientific evidence and have drawn up an agreed series of recommendations on the diagnosis, treatment and follow-up of patients. We recommend establishing enzyme treatment in any patient with symptomatic Pompe disease with onset within the first year of life, with a clinical and enzymatic diagnosis, and once the CRIM (cross-reactive immunological material) status is known.

    2015-01-01

    Objective:The objective of this study was to review the research on clinical genetics of Wilson's disease (WD).Data Sources:We searched documents from PubMed and Wanfang databases both in English and Chinese up to 2014 using the keywords WD in combination with genetic,ATP7B gene,gene mutation,genotype,phenotype.Study Selection:Publications about the ATP7B gene and protein function associated with clinical features were selected.Results:Wilson's disease,also named hepatolenticular degeneration,is an autosomal recessive genetic disorder characterized by abnormal copper metabolism caused by mutations to the copper-transporting gene A TP7B.Decreased biliary copper excretion and reduced incorporation of copper into apoceruloplasmin caused by defunctionalization of ATP7B protein lead to accumulation of copper in many tissues and organs,including liver,brain,and cornea,finally resulting in liver disease and extrapyramidal symptoms.It is the most common genetic neurological disorder in the onset of adolescents,second to muscular dystrophy in China.Early diagnosis and medical therapy are of great significance for improving the prognosis of WD patients.However,diagnosis of this disease is usually difficult because of its complicated phenotypes.In the last 10 years,an increasing number of clinical studies have used molecular genetics techniques.Improved diagnosis and prediction of the progression of this disease at the molecular level will aid in the development of more individualized and effective interventions,which is a key to transition from molecular genetic research to the clinical study.Conclusions:Clinical genetics studies are necessary to understand the mechanism underlying WD at the molecular level from the genotype to the phenotype.Clinical genetics research benefits newly emerging medical treatments including stem cell transplantation and gene therapy for WD patients.

    Karlsen, Tom H; Lammert, Frank; Thompson, Richard J

    2015-04-01

    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.

  13. Podometrics as a Potential Clinical Tool for Glomerular Disease Management.

    Kikuchi, Masao; Wickman, Larysa; Hodgin, Jeffrey B; Wiggins, Roger C

    2015-05-01

    Chronic kidney disease culminating in end-stage kidney disease is a major public health problem costing in excess of $40 billion per year with high morbidity and mortality. Current tools for glomerular disease monitoring lack precision and contribute to poor outcome. The podocyte depletion hypothesis describes the major mechanisms underlying the progression of glomerular diseases, which are responsible for more than 80% of cases of end-stage kidney disease. The question arises of whether this new knowledge can be used to improve outcomes and reduce costs. Podocytes have unique characteristics that make them an attractive monitoring tool. Methodologies for estimating podocyte number, size, density, glomerular volume and other parameters in routine kidney biopsies, and the rate of podocyte detachment from glomeruli into urine (podometrics) now have been developed and validated. They potentially fill important gaps in the glomerular disease monitoring toolbox. The application of these tools to glomerular disease groups shows good correlation with outcome, although data validating their use for individual decision making is not yet available. Given the urgency of the clinical problem, we argue that the time has come to focus on testing these tools for application to individualized clinical decision making toward more effective progression prevention.

    2015-01-01

    Objective: To estimate the prevalence of prodromal clinical features of neurodegeneration in patients with Anderson-Fabry disease (AFD) in comparison to age-matched controls. Methods: This is a single-center, prospective, cross-sectional study in 167 participants (60 heterozygous females and 50 hemizygous males with genetically confirmed AFD, 57 age-matched controls) using a clinical screening program consisting of structured interview, quantitative tests of motor function, and assessments of cognition, depression, olfaction, orthostatic intolerance, pain, REM sleep behavior disorder, and daytime sleepiness. Results: In comparison to age-matched controls (mean age 48.3 years), patients with AFD (mean age 49.0 years) showed slower gait and transfer speed, poorer fine manual dexterity, and lower hand speed, which was independent of focal symptoms due to cerebrovascular disease. Patients with AFD were more severely affected by depression, pain, and daytime sleepiness and had a lower quality of life. These motor and nonmotor manifestations significantly correlated with clinical disease severity. However, patients with AFD did not reveal extrapyramidal motor features or signs of significant cognitive impairment, hyposmia, orthostatic intolerance, or REM sleep behavior disorder, which commonly precede later neurodegenerative disease. In our cohort, there were no differences in neurologic manifestations of AFD between heterozygous females and hemizygous males. Conclusions: Aside from cerebrovascular manifestations and small fiber neuropathy, AFD results in a distinct neurologic phenotype comprising poorer motor performance and specific nonmotor features. In contrast to functional loss of glucocerebrosidase in Gaucher disease, α-galactosidase deficiency in AFD is not associated with a typical cluster of clinical features prodromal for neurodegenerative diseases, such as Parkinson disease.

    By means of repeated, well-supported measurements of clinical dynamic indicators from the Historical, Clinical and Future - 30 (HKT-30) it is possible to monitor behavioural changes on the basis of risks and needs. The addition of extra score parameters allows us to distinguish client-specific risks and needs. In treatment evaluation it is important to visualise changes in these indicators of treatment evaluation because they are the key to the clinical decision-making process that determines further treatment and rehabilitation. To investigate whether HKT-30 indicators can be used to measure and visualise behavioral changes for the purpose of treatment evaluation. A case study is used to illustrate how clinicians at the Forensic Psychiatric Clinic (FPK), De Woenselse Poort, ascertain risks, needs and changes and clarify these factors for the purpose of treatment evaluation and clinical decision-making. Routine treatment evaluation aided by visualised clinical HKT-30 indicators give the treatment team and the client a clearer picture of the behavioral changes for which the forensic treatment was prescribed. This evaluation provides significant starting-points for clinical decision making. Routine treatment evaluation along with a suitably adjusted HKT-30 make behavioural changes visible, render clinical decisions more transparent and provide valuable starting-points for a dialogue with the client about his treatment.

    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.

    We evaluated the association of stress,distress, and coping behaviors with periodontal disease in 1,426 subjects, aged 25 to 74, in Erie County, NY, Demographic characteristics, medical and dental history, and tobacco and alcohol consumption, as well as clinical assessments of supragingival plaque, subgingival flora, gingival bleeding, calculus, probing depth, clinical attachment level (CAL), and radiographic alveolar bone loss (ABL) were obtained for each subject. Subjects also completed a set of 5 psychosocial instruments that measured life events, daily strains, hassles and uplifts, distress, and coping behaviors. Internal consistencies of all subscales on the instruments were high, with Cronbach's alpha ranging from 0.88 to 0.99. Logistic regression indicated that financial strain was significantly associated with greater attachment and alveolar bone loss (OR 1.70; 95% CI, 1.09-2.65; and 1.68; 95% CI, 1.20-2.37, respectively) after adjusting for age, gender, and smoking. When those with financial strain were stratified with respect to coping behaviors, it was found that those who exhibited high emotion-focused coping (inadequate coping) had and even higher risk of having more severe attachment loss (OR 2.24; 95% CI, 1.15-4.38) and alveolar bone loss (OR 1.91; 95% CI, 1.15-3.17) than those with low levels of financial strain within the same coping group, after adjustment for age, gender, and cigarette smoking. After further adjusting for number of visits to the dentist, those with financial strain who were high emotion-focused copers still had higher levels of periodontal disease based on CAL (OR 2.12; 95% CI, 1.07-4.18). In contrast, subjects with high levels of financial strain who reported high levels of problem-based coping (good coping) had no more periodontal disease than those with low levels of financial strain. Salivary cortisol levels were higher in a test group exhibiting severe periodontitis, a high level of financial strain, and high emotion

    Full Text Available Objective: To demonstrate a method of evaluating accuracy of developmental screening modeled on the evidence-based medical literature. Method: A retrospective review was performed on 418 children screened with the Denver II by a trained technician. Two models for analyzing screening data were examined, using predictive values and likelihood ratios (LR+ and LR−. Results: The technician, working at 20% time, screened 44% of eligible children. There were 129/418 (31% children with Suspect Denver II results, 115/418 who were referred, 81/115 (70% who were evaluated by Early Intervention, and 64/81 (79% who qualified for services. The uncorrected positive predictive value for the Denver II alone (44% was insufficient to meet the preset standard of 60%, but the LR+ of 4.16 indicated a significant contribution of test information to improving predictive value. Combining test results with information from the parent–technician conference to achieve a referral decision resulted in an uncorrected predictive value of 56%, which rose with correction for children referred but not evaluated to 72% (LR+ 10.33. Negative predictive values and likelihood ratios of a negative test and a non-referral decision achieved recommended levels. Parents who expressed concern were significantly more likely to complete recommended evaluation than those who did not (82% vs 58%, p < .01. Results were in the same range as in published studies with other screening tests but showed three areas for improvement: screening more children, more carefully supervising some referral decisions, and getting more children to evaluation. Conclusion: Levels of predictive accuracy above 60% can be obtained by combining different types of information about development to make decisions about referral for more complete evaluation. Systematic study of such combinations could lead to improved predictive accuracy of screening programs and support attempts to close the gap between referral

    Clinical librarian services have been in existence for over 40 years. Although three systematic reviews have examined clinical librarian roles they continue to pose a challenge to rigorous evaluation. Difficulties can be articulated around their Population, Intervention, Comparator and Outcome (PICO) characteristics as well as within a wider evaluation framework. This feature suggests that developments within health research aimed at evaluating complex interventions may hold the key to assessing the contribution of such a variety of service models.

    Full Text Available A anemia falciforme está entre as doenças genéticas mais comuns e mais estudadas em todo o mundo. Ela é causada por mutação no gene β, produzindo alteração estrutural na molécula da hemoglobina. As moléculas de HbS, decorrentes da mutação, sofrem processo de polimerização fisiologicamente provocado pela baixa tensão de oxigênio, acidose e desidratação. Com isso, os eritrócitos passam a apresentar a forma de foice, causando vaso-oclusão e outras conseqüências. O objetivo desse estudo foi revisar a importância da hemoglobina fetal na clínica de pacientes portadores de anemia falciforme. O significado clínico da associação da elevação da hemoglobina fetal na anemia falciforme mostra-se favorável em termos hematológicos, pois, nessa interação, as células-F têm baixas concentrações de HbS e, com isso, inibem a polimerização da HbS e a alteração da morfologia dos eritrócitos. O tratamento com hidroxiuréia, em função do aumento na expressão da hemoglobina fetal que este fármaco proporciona, traz aos pacientes falcêmicos uma melhora significativa em sua clínica. Portanto, a hemoglobina fetal consiste no maior inibidor da polimerização da desoxi-HbS e, com isso, evita a falcização do eritrócito, a anemia hemolítica crônica, as crises dolorosas vaso-oclusivas, o infarto e a necrose em diversos órgãos, melhorando a clínica e a expectativa de vida dos pacientes.Sickle cell disease is one of the commonest and most studied genetic diseases in the world. Caused by a mutation of the β gene, it changes the molecular structure of hemoglobin. Abnormal Hb S molecules suffer polymerization physiologically provoked by a low oxygen tension, acidosis and dehydration.

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.

    Posaconazole, a broad-spectrum triazole antifungal agent, is approved for the prevention of invasive aspergillosis and candidiasis in addition to the treatment of oropharyngeal candidiasis. There is evidence of efficacy in the treatment and prevention of rarer, more difficult-to-treat fungal infections. Posaconazole oral suspension solution has shown limitations with respect to fasting state absorption, elevated gastrointestinal pH and increased motility. The newly approved delayed-release oral tablet and intravenous solution formulations provide an attractive treatment option by reducing interpatient variability and providing flexibility in critically ill patients. On the basis of clinical experience and further clinical studies, posaconazole was found to be a valuable pharmaceutical agent for the treatment of life-threatening fungal infections. This review will examine the development history of posaconazole and highlight the most recent advances.

This chronic cerebral angiopathy is observed in children and adults. It mainly leads to brain ischemic events in children, and to ischemic and hemorrhagic events in adults. This is a rare condition, with a marked prevalence gradient between Asian countries and Western countries. Two main nosological entities are identified. On the one hand, moyamoya disease corresponds to isolated moyamoya angiopathy, defined as being “idiopathic” according to the Guidelines of the Research Committee on the Pathology and Treatment of Spontaneous Occlusion of the Circle of Willis. This entity is probably multifactorial and polygenic in most patients. On the other hand, moyamoya syndrome is a moyamoya angiopathy associated with an underlying condition and forms a very heterogeneous group with various clinical presentations, various modes of inheritance, and a variable penetrance of the cerebrovascular phenotype. Diagnostic and evaluation techniques rely on magnetic resonance imaging (MRI, magnetic resonance angiography (MRA conventional angiography, and cerebral hemodynamics measurements

    Full Text Available Hirayama disease (juvenile muscular atrophy of distal upper extremity is a cervical myelopathy predominantly affecting adolescent males. It is characterized by progressive muscular weakness and atrophy of unilateral or asymmetrically bilateral distal upper limbs. We report a case of an 18-year-male painter, who presented with gradually progressive, symmetrical bilateral weakness of hands and forearm for the last two years. On the basis of clinical examination, a provisional diagnosis of lower motor neuron type of symmetrical distal weakness due to heavy metal intoxication was kept. However, imaging studies helped in making a definitive diagnosis of Hirayama disease. The patient was advised cervical collar, and there was no progression in symptoms after six months of followup. Due to the rarity of bilateral symmetrical involvement in Hirayama disease, it remains obscured or unsuspected clinically, and MRI plays a pivotal role in diagnosis.

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.

  1. Rubrics for clinical evaluation: objectifying the subjective experience.

    Science.gov (United States)

    Isaacson, Julie J; Stacy, Annette S

    2009-03-01

    Rubrics have historically been used in secondary and higher education to evaluate specific assignments or tasks. There is little mention of rubrics in the nursing literature, particularly in the area of clinical evaluation. A strong case can be made for expanding the traditional use of a rubric to include its validity with clinical evaluation. Clinical evaluation remains a challenge, even for seasoned faculty. Faculty and students often interpret clinical course objectives differently. Coupled with this concern is the subjectivity of the evaluation. The use of "novice" clinical faculty, who inevitably struggle with discerning and justifying anything but stellar student performance, further compounds these issues. Rubrics also facilitate the grading experience for faculty and students. Faculty often find themselves making repetitive written comments to students. These comments can be incorporated into the rubric, thus shortening grading time while increasing the quality and quantity of instructor feedback. When clarified in a rubric, course objectives become "real". Student benefits include increased critical thinking and a more realistic approach to self-evaluation. Clinical rubrics can be developed from existing course objectives. Though perhaps tedious in initial development, both faculty and student satisfaction with the clinical evaluation process can be enhanced with the use of rubrics.

    AIM: To analyze systematically our experience over 22 years with symptomatic acquired diverticular disease of the jejunum and ileum, exploring the clinical manifestations and diagnosis of this rare but life-threatening disease.METHODS: The medical records of patients with surgically confirmed symptomatic jejunoileal diverticular disease were retrospectively reviewed. Data collected included demographic data, laboratory results, clinical course (acute or chronic), preoperative diagnosis, and operative findings. Inclusion criteria were as follows: (1) surgical confirmation of jejunoileal diverticular disease and (2)exclusion of congenital diverticula (e.g. Meckel's diverticulum).RESULTS: From January 1982 to July 2004, 28 patients with a total of 29 operations met the study criteria. The male:female ratio was 14:14, and the mean age was 62.6±3.5 years. The most common manifestation was abdominal pain. In nearly half of the patients, the symptoms were chronic. Two patients died after surgery. Only four cases were correctly diagnosed prior to surgery, three by small bowel series.CONCLUSION: Symptomatic acquired small bowel diverticular disease is difficult to diagnose. It should be considered in older patients with unexplained chronic abdominal symptoms. A small bowel series may be helpful in diagnosing this potentially life-threatening disease.

    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.

Mean age of the patients was 55.3±14.5 (15–88 years, and the male/female ratio was 45/190. The baseline pulmonary function test results of the patients were as follows: mean forced vital capacity (FVC values 2,825±1,108 (710–6,870 mL and 74.3±22.4 (24–155%, forced expiratory volume in 1 second (FEV1 values 1,789±774 (480–4,810 mL and 58.1±20.0 (20–130%, FEV1/FVC values 62.5±6.8 (39–70%. Reversibility criteria following bronchodilator treatment were present in 107 (45.5% patients. We specified five subgroups for patients according to their clinical, radiological, and pulmonary test findings, namely Group 1 (asthma, Group 2 (ACOS, Group 3 (chronic bronchitis, and Group 4 (emphysema. Additionally, a group of patients who had clinical and spirometric features of both asthma and chronic bronchitis in association with underlying emphysema (emphysema with chronic bronchitis and emphysema with asthma

    The recognition that inflammatory events in the airways play a key role in the pathogenesis of asthma has led to a relentless search for pharmacological agents which modify these processes. Nedocromil sodium (Tilade) represents one such agent. Nedocromil sodium, when inhaled by patients with asthma (0.05-0.50% nebulized, 0.5-4.0 mg m.d.i.), has been shown to inhibit immediate bronchoconstriction provoked by challenges with allergen (10 studies), exercise (five studies), isocapnic hyperventilation, fog and sulphur dioxide (one study each) and adenosine (two studies). With these challenges, inhibition of bronchoconstriction exhibited dose-dependency up to 4 mg, with nedocromil sodium being up to four times more potent than sodium cromoglycate. When inhaled prior to allergen provocation, nedocromil sodium inhibited the late asthmatic reaction; when taken regularly during the pollen season, it attenuated the allergen-induced increase in non-specific bronchial responsiveness. The efficacy of nedocromil sodium (4 mg q.i.d.) in the treatment of clinical asthma was initially shown in four open studies and subsequently confirmed in nine double-blind, placebo-controlled 4-12 week studies on patients with seasonal and perennial asthma. Further clinical trials (eight studies) identified some difficulty in replacing inhaled corticosteroids with nedocromil sodium, especially if the corticosteroids were reduced rapidly (four studies). However, two studies have shown that nedocromil sodium produced further improvement in asthma symptoms when used in addition to bronchodilators and inhaled corticosteroids. Treatment with nedocromil sodium (4 mg q.i.d.) for up to 52 weeks demonstrated a progressive reduction in bronchodilator usage throughout the whole treatment period. During clinical assessment, nedocromil sodium was well tolerated, side-effects being unpleasant taste, nausea and headache. In most cases the adverse reactions were mild and transient, although in approximately 3% of

    Full Text Available Emilie Vallières, Joseph Stuart ElbornCystic Fibrosis and Airways Microbiology Research Group, Queens University Belfast, Belfast, UKAbstract: The cystic fibrosis transmembrane regulator (CFTR gene encodes an ion channel transporter, the CFTR protein. Since its identification in 1989, more than 1,900 sequence variants have been reported, resulting in a wide spectrum of clinical phenotypes. Cystic fibrosis (CF is associated with many CFTR mutants and there is a continuum of disease severity observed. Recent advances in fundamental research have increased our understanding of the consequent molecular defect arising from CF mutations. This knowledge has resulted in the development of CF-specific therapies, targeting either the genetic or the molecular defect. CF care, previously focused on symptom control, is therefore moving toward a "stratified" or "precision" therapeutic approach. This review outlines normal CFTR physiology, the proposed pathologic mechanism underlying CF associated-lung injury, classification of CF mutations, and the CF-specific therapies recently approved or in clinical trials.Keywords: cystic fibrosis, gene mutations, disease severity, evaluation, assessment

    Disease management has emerged as a new strategy to enhance quality of care for patients suffering from chronic conditions, and to control healthcare costs. So far, however, the effects of this strategy remain unclear. Although current models define the concept of disease management, they do not provide a systematic development or an explanatory theory of how disease management affects the outcomes of care. The objective of this paper is to present a framework for valid evaluation of disease-management initiatives. The evaluation model is built on two pillars of disease management: patient-related and professional-directed interventions. The effectiveness of these interventions is thought to be affected by the organisational design of the healthcare system. Disease management requires a multifaceted approach; hence disease-management programme evaluations should focus on the effects of multiple interventions, namely patient-related, professional-directed and organisational interventions. The framework has been built upon the conceptualisation of these disease-management interventions. Analysis of the underlying mechanisms of these interventions revealed that learning and behavioural theories support the core assumptions of disease management. The evaluation model can be used to identify the components of disease-management programmes and the mechanisms behind them, making valid comparison feasible. In addition, this model links the programme interventions to indicators that can be used to evaluate the disease-management programme. Consistent use of this framework will enable comparisons among disease-management programmes and outcomes in evaluation research.

    Awareness of cognitive deficits and clinical competence were investigated in 79 mild to moderate Alzheimer's disease patients. Awareness was assessed by the anosognosia questionnaire for dementia, and clinical competence by specific neuropsychological tests such as trail making test-A, Babcock story recall test, semantic and phonemic verbal fluency. The findings show that 66 % of the patients were aware of memory deficits, while the 34 % were unaware. Deficit in awareness correlated with lower scores on the Mini Mental State Examination test that, in the score range from 24.51 to 30 and from 19.50 to 24.50, appeared to be a significant predictor of level of awareness. None of the AD patients had fully preserved clinical competence, only 7 patients (9 %) had partially preserved clinical competence and 72 patients (91 %) had completely lost clinical competence. All the patients with partially preserved clinical competence (9 %) were aware of their memory deficit. The study indicates that neuropsychological tests used for the assessment of executive functions are not suitable for investigating clinical competence. Therefore, additional and specific tools for the evaluation of clinical competence are necessary. Indeed, these might allow clinicians to identify AD patients who, despite their deficits in selected functions, retain their autonomy of choice as well as recognize those patients who should proceed to the nomination of a legal representative.

    Osteogenesis Imperfecta (OI) is a genetic disease, in which the main clinical features are increased bone fragility, pathological fractures, blue sclera, dentinogenesis imperfecta and conductive or mixed hearing loss. Clinical variability is wide. Although there is no curative treatment, there are several therapeutic tools capable of improving the course of the condition and patient quality of life. Sixty-five children seen in a Paediatric Hospital during six months in 2007 were evaluated. Thirty-five were type I OI, and thirty were types III-IV. Median age was 7.8 years (range 1.9-19.2); mean length of follow up was 4.7 years. The majority of children attended regular school for their corresponding age. Mean height was -1.4 sDS and -5.64 sDS in types I and III-IV respectively. Nineteen percent of patients were overweight and 11% were obese. Mean age at first orthopaedic surgery inserting telescopic rods was 6.5 years. Scoliosis was present in 44.6% of patients and was directly related to severity. Bleck's motor scale showed that 93% of patients with mild forms and 29% of severe forms had a sustainable walking ability. A wheelchair was used by 25% of patients. Family inheritance was confirmed in 65% of cases. Integral care using a multidisciplinary approach is required due to the complexity and clinical variability of the condition.

    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.

    To share outcomes and lessons learned from an evaluation of disease management (DM) programs for asthma, congestive heart failure (CHF), and diabetes for TRICARE patients. Multiyear evaluation of participants in voluntary, opt-out DM programs. Patient-centered programs, administered by 3 regional contractors, provide phone-based consultations with a care manager, educational materials, and newsletters. The study sample consisted of 23,793 asthma, 4092 CHF, and 29,604 diabetes patients with at least 6 months' tenure in the program. Medical claims were analyzed to quantify program effect on healthcare utilization, medical costs, and clinical outcomes. Multivariate regression analysis with an historical control group was used to predict patient outcomes in the absence of DM. The difference between actual and predicted DM patient outcomes was attributed to the program. A patient survey collected data on program satisfaction and perceived usefulness of program information and services. Modest improvements in patient outcomes included reduced inpatient days and medical costs, and (with few exceptions) increased percentages of patients receiving appropriate medications and tests. Annual per patient reductions in medical costs were $453, $371, and $783 for asthma, CHF, and diabetes program participants, respectively. The estimated return on investment was $1.26 per $1.00 spent on DM services. Findings suggest that the DM programs more than pay for themselves, in addition to improving patient health and quality of life. Lessons learned in program design, implementation, effectiveness, and evaluation may benefit employers contemplating DM, DM providers, and evaluators of DM programs.

    Full Text Available Abstract Dementia with Parkinson's disease represents a controversial issue in the complex group of alpha-synucleinopathies. The author acknowledges the concept of a "continuum" between Parkinson disease's (PD, Lewy body dementia (LBD, and dementia in Parkinson's disease (PDD. However, the practicing neurologist needs to identify the phenotypic signs of each dementia. The treatment and prognosis are different in spite of the overlaps between them. The main aim of this review was to characterize the clinical diagnoses of dementia associated with Parkinson's disease (PDD. Secondarily, the review discussed some epidemiological and neuropsychological issues. Selection of articles was not systematic and reflects the author's opinion, where the main text selected was the recommendations from the Movement Disorder Society Task Force for PDD diagnosis. The Pub Med, OVID, and Proquest data bases were used for the search.

    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.

    A unit for digital TV tomography (DTT) was constructed on the basis of retrospective reconstruction of digital data acquired during a linear tomographic motion of an X-ray tube and an image intensifier with a television camera (I.I.-TV) assembly. Following descriptions of the basic principle and system, clinical results obtained with this unit are presented. Comparison with conventional tomography of the chest, skull, abdomen, and bones and joints showed equal diagnostic information in more than 50% of cases. Application to intra-arterial and intravenous DSA provided excellent images, but no new information was obtained. DTT has the advantages of technical simplicity, short examination time, low exposure dose, and compatibility with a PACS system. This technique will become an important part of a modern radiology department. (author).

    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.

The available literature has been reviewed for motor, cognitive, and psychiatric alterations, which are the three major symptom domains of this devastating progressive disease. From a clinical point of view, one has to be aware that the HD phenotype can vary highly across individuals and during the course of the disease. Also, symptoms in juvenile HD can differ substantially from those with adult-onset of HD. Although there is no cure of HD and management is limited, motor and psychiatric symptoms often respond to pharmacotherapy, and nonpharmacological approaches as well as supportive care are essential. International treatment recommendations based on study results, critical statements, and expert opinions have been included. This review is restricted to symptomatic and supportive approaches since all attempts to establish a cure for the disease or modifying therapies have failed so far.

    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

    More men than women are diagnosed with Parkinson's disease (PD), and a number of gender differences have been documented in this disorder. Examples of clinical characteristics that appear in men more often than women include rigidity and rapid eye movement behavior disorder, whereas more women than men exhibit dyskinesias and depression. Differences between men and women in cognition have not been extensively examined, though there are reports of deficits in men in aspects of cognition that contribute to activities of daily living, in verbal fluency, and in the recognition of facial emotion, and deficits in women in visuospatial cognition. Side of disease onset may interact with gender to affect cognitive abilities. One possible source of male-female differences in the clinical and cognitive characteristics of PD is the effect of estrogen on dopaminergic neurons and pathways in the brain. This effect is not yet understood, as insight into how the fluctuation of estrogen over the lifetime affects the brain is currently limited. Further attention to this area of research will be important for accurate assessment and better management of PD. Attention should also be directed to multiple covariates that may affect clinical characteristics and cognition. Knowledge about differences in the presentation of PD symptoms in men and women and about the pathophysiology underlying those differences may enhance the accuracy and effectiveness of clinical assessment and treatment of the disease.

It provides pure heart rate reduction, reducing the diastolic depolarization slope, without altering hemodynamic parameters. This review summarizes the current knowledge on the efficacy of ivabradine in patients with cardiovascular diseases, with a particular focus on its role in the clinical management of patients with CAD and HF. There is consistent evidence that ivabradine is effective in reducing angina pectoris symptoms and myocardial ischemia. At approved doses ivabradine is safe, improves exercise tolerance, and reduces heart rate. Available data from clinical trials support its use in the management of patients with stable CAD and chronic HF. Recent studies have cast doubt on the safety of non-approved high doses of ivabradine for the treatment of patients with CAD and without clinical HF, but have shown no concerns on the doses approved for clinical use.

    Full Text Available The South African Qualifications Authority, and the South African Nursing Council are in pursuit of quality nursing education to enable the learners to practise as independent and autonomous practitioners. The educational programme should focus on the facilitation of critical and reflective thinking skills that will help the learner to make rational decisions and solve problems. A way of achieving this level of functioning is the use of assessment and evaluation methods that measure the learners’ clinical competence holistically. This article is focused on the perceptions of twenty nurse educators, purposively selected from three Nursing Colleges affiliated to a university in Gauteng, regarding the use of OSCE (Objective Structured Clinical Examination as a clinical evaluation method within a qualitative and descriptive research strategy. Three focus group interviews were conducted in different sessions. A descriptive content analysis was used. Trustworthiness was ensured by using Lincoln and Guba’s model (1985. The results revealed both positive and negative aspects of OSCE as a clinical evaluation method with regard to: administrative aspects; evaluators; learners; procedures/instruments and evaluation. The conclusion drawn from the related findings is that OSCE does not measure the learners’ clinical competence holistically. It is therefore recommended that the identified negative perception be taken as challenges faced by nurse educators and that the positive aspects be strengthened. One way of meeting these recommendations is the use of varied alternative methods for clinical assessment and evaluation that focus on the holistic measurement of the learners’ clinical competence.

    Many hospitalized patients have at least 1 chronic disease that is not optimally controlled. The purpose of this study was to explore inpatient provider attitudes about chronic disease management and, in particular, barriers and facilitators of chronic disease management in the hospital. We conducted a qualitative study of semi-structured interviews of 31 inpatient providers from an academic medical center. We interviewed attending physicians, resident physicians, physician assistants, and nurse practitioners from various specialties about attitudes, experiences with, and barriers and facilitators towards chronic disease management in the hospital. Qualitative data were analyzed using constant comparative analysis. Providers perceived that hospitalizations offer an opportunity to improve chronic disease management, as patients are evaluated by a new care team and observed in a controlled environment. Providers perceived clinical benefits to in-hospital chronic care, including improvements in readmission and length of stay, but expressed concerns for risks related to adverse events and distraction from the acute problem. Barriers included provider lack of comfort with managing chronic diseases, poor communication between inpatient and outpatient providers, and hospital-system focus on patient discharge. A strong relationship with the outpatient provider and involvement of specialists were facilitators of inpatient chronic disease management. Providers perceived benefits to in-hospital chronic disease management for both processes of care and clinical outcomes. Efforts to increase inpatient chronic disease management will need to overcome barriers in multiple domains. Journal of Hospital Medicine 2017;12:162-167.

    Full Text Available The purpose of our study was to outline the evaluation of the Peyronie's disease (PD patient and review the available nonsurgical treatments. A review of the literature on oral, intralesional, external energy, iontophoresis, and mechanical therapies for PD was performed. PubMed was utilized to find all published articles, and several meeting abstracts were reviewed for data ahead of publication. Our medical evaluation of the PD patient is described. The published results of available treatment options are reviewed, with recommendation by the authors for appropriate nonsurgical management of PD. There are no available validated questionnaires for PD, but a thorough history and focused physical examination, including measurement of erect penile deformity, will help the clinician make the diagnosis and guide treatment options. Although there are many published reports that show efficacy of nonsurgical therapies for PD, there is a lack of large-scale, multicenter, controlled clinical trials, which makes treatment recommendations difficult. Careful review of the literature does suggest that there are treatment options that make scientific sense and appear to stabilize the disease process, reduce deformity, and improve function. Offering no treatment at all will encourage our patients to pursue alternative treatments that may do harm, and misses the opportunity to do some good. Clearly, further work is necessary to develop safe and effective nonsurgical treatments for PD.

    The aim of this investigation was to evaluate the efficacy and convenience of decayed dentine removal with N-monochloro-DL-2 aminobutyrate (CARIDEX) in all classes of cavities. Fifty-seven patients, each with two teeth having similarly sized carious cavities, participated in this study. One cavity in each patient was treated with the chemomechanical CARIDEX technique and the other cavity was treated with conventional mechanical drilling. The cavities were restored with either amalgam, composite or glass ionomer restorative materials. The time taken for access and caries removal was noted and the efficacy of caries removal with each technique was evaluated. The chemomechanical caries removal technique was effective in removing 90-100% of decayed dentine in 98% of the cavities treated. Multiple regression adjusted access and caries removal time to account for volume of caries removed. This adjusted time was operator dependent, and ranged from 4 to 10 minutes longer for CARIDEX than for the conventional technique. Ninety-three per cent of patients preferred the chemomechanical method of caries removal over the conventional technique (highly significant P less than 0.001). Even though the chemomechanical removal of caries is slower than the conventional technique, the efficacy of CARIDEX and its high patient acceptance provides a viable alternative method for dentinal caries removal in all classes of cavities.

    Protein aggregation within the central nervous system has been recognized as a defining feature of neurodegenerative diseases since the early 20th century. Since that time, there has been a growing list of neurodegenerative disorders, including Parkinson disease, which are characterized by inclusions of specific pathogenic proteins. This has led to the long-held dogma that these characteristic protein inclusions, which are composed of large insoluble fibrillar protein aggregates and visible by light microscopy, are responsible for cell death in these diseases. However, the correlation between protein inclusion formation and cytotoxicity is inconsistent, suggesting that another form of the pathogenic proteins may be contributing to neurodegeneration. There is emerging evidence implicating soluble oligomers, smaller protein aggregates not detectable by conventional microscopy, as potential culprits in the pathogenesis of neurodegenerative diseases. The protein α-synuclein is well recognized to contribute to the pathogenesis of Parkinson disease and is the major component of Lewy bodies and Lewy neurites. However, α-synuclein also forms oligomeric species, with certain conformations being toxic to cells. The mechanisms by which these α-synuclein oligomers cause cell death are being actively investigated, as they may provide new strategies for diagnosis and treatment of Parkinson disease and related disorders. Here we review the possible role of α-synuclein oligomers in cell death in Parkinson disease and discuss the potential clinical implications.

    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.

    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.

    Huntington disease was one of the first neurological hereditary diseases for which genetic testing was made possible as early as 1993. The study describes the clinical and genetic characteristics of patients with Huntington disease in Sri Lanka. Data of 35 consecutive patients tested from 2007 to 2012 at the Human Genetics Unit, Faculty of Medicine, University of Colombo was analyzed retrospectively. Clinical data and genetic diagnostic results were reviewed. Statistical analysis was performed using descriptive statistics. Thirty patients had fully penetrant (FP) CAG repeat mutations and 5 had reduced penetrant (RP) CAG repeat mutations. In the FP group mean ages of onset and diagnosis were 37.5 and 40.4 years, while in the RP group it was 63.0 and 64.8 years respectively. The age of diagnosis ranged from 15 to 72 years, with 2 patients with Juvenile onset (60 years) Huntington disease. The symptoms at diagnosis were predominantly motor (32/35 -91%). Three patients had psychiatric and behavioral disorders. The age difference between onset and genetic diagnosis showed significant delay in females compared to males (p Huntington disease in the Sri Lankan study population were similar to that previously reported in literature.

    Expensive and lengthy clinical trials can delay regulatory evaluation and add significant burden that stifles innovation affecting patient access to novel, high-quality imaging technologies. In silico imaging holds promise for evaluating the safety and effectiveness of imaging technologies with much less burden than clinical trials. We define in silico imaging as a computer simulation of an entire imaging system (including source, object, task, and observer components) used for research, development, optimization, technology assessment, and regulatory evaluation of new technology. In this work we describe VICTRE (our study of virtual imaging clinical trials for regulatory evaluation) and the considerations for building an entire imaging pipeline in silico including device (physics), patient (anatomy, disease), and image interpretation models for regulatory evaluation using open-source tools.

    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

    Full Text Available Aim. While there are many well-defined serological markers for inflammatory bowel disease (IBD, there is limited evidence that they positively affect clinical outcomes. This study aimed to evaluate the correlation between hepcidin serum levels and disease activity in IBD. Materials and Methods. Eighty-five consecutive IBD patients were enrolled in the study. Hepcidin serum levels were assessed using an enzyme-linked immunosorbent assay (ELISA and were compared with disease activity as well as the interleukin-6 (IL-6 and C-reactive protein (CRP levels. Results. The mean hepcidin serum levels in Crohn’s disease (CD patients in remission and in the active phase were 3837±1436 and 3752±1274 pg/mL, respectively P=0.613. The mean hepcidin serum levels in ulcerative colitis (UC patients in remission and in the active phase were 4285±8623 and 3727±1176 pg/mL, respectively P=0.241. Correlation analysis between inflammatory markers and hepcidin serum levels indicated that there was no correlation between hepcidin levels and IL-6 P=0.582 or CRP P=0.783. Conclusion. As an acute-phase protein, hepcidin seems to have a lower efficacy than other parameters in the detection of activation in IBD.
