The authors assessed the prevalence of compulsive buying (CB) among patients presenting an obsessive-compulsive disorder (OCD). They compared the buying style of patients with and without CB. One thousand five hundred consecutive patients were assessed by a general practitioner in Paris (France). Sixty patients presenting with OCD were included. Patients with CB associated with OCD (n = 14) were compared with those with "pure" OCD (n = 46). Sixty patients paired for sex and age and free from OCD, depression, and anxiety were also recruited among the clients of the same general practitioner. We compared 3 groups: controls, patients with OCD, and patients with OCD + CB. Prevalence of CB was 23% (14 cases) among patients with OCD and 6% (4 cases) in controls (chi(2)(1) = 5.3, P = .02). Patients presenting with OCD + CB had a higher number of Diagnostic and Statistical Manual of Mental Disorders, Revised Fourth Edition diagnostic criteria for OCD than patients with pure OCD (6.1 and 5.4, respectively, P = .001). Depression was more frequent in the OCD + CB group (78%) than in the OCD group (42%) and in controls (10%) (P = .02). Patients from the OCD + CB group had higher score at the CAGE questionnaire than those of the OCD group (2 vs 0.7, P = .003). Patients with OCD + CB considered 42% of their purchases as occasions not to be passed up compared with 15.4% in the OCD group and 8.6% in controls. OCD+CD patients used the items they bought after a longer delay than controls and patients with pure OCD (8.2 vs 3 and 3.1 days, respectively). Compulsive buying is more frequent in OCD than in controls. Patients presenting with OCD + CB show more depressive disorders and drink more alcohol. They are more highly implicated in the items they buy and they are more often disappointed by the items once they possess them.

The frequency of emergency colon cancer (ECC) was determined using a reproducible definition of 'emergency' to analyse the impact of mode of presentation on long-term prognosis and to search for risk factors for an emergency presentation. All patients with colon cancer treated at one Swedish GDH between 1996 and 2005 (N = 604) were eligible. Patients admitted through the emergency room, operated on within three days and with an emergency condition confirmed at surgery were classified as ECC. Survival was analysed by Kaplan-Meier estimates and risk of death by Cox regression. The rate of ECC was 97/585 (17%). Patients with ECC were older (median 77 vs 74, P = 0.02), they had more stage III and IV cancers (65%vs 47%; χ(2) = 9.4, P Emergency presentation of colon cancer is an independent and adverse risk factor for long-term survival. The causes of a seasonal variation need to be clarified. © 2011 The Authors. Colorectal Disease © 2011 The Association of Coloproctology of Great Britain and Ireland.

Nocturia is a frequent complaint in the population of idiopathic Parkinson's disease patients (IPD). The consequences of nocturia in the IPD population are at high importance as these patients have motor problems and therefore a risk of nocturnal fall. The aim of the study was to determine the mechanism of nocturia in patients with MPI, by determining the prevalence of nocturnal polyuria (NP) in this population. A prospective study by bladder diary was conducted on 70 consecutive IPD patients consulting for regular neurological follow-up at a non-severe stage. Nocturia was defined as 1 or more awakenings to urinate. Two definitions of NP were used: nocturnal diuresis 33% or higher of the total diuresis (NUV33), which is the ICS (International Continence Society) definition, and nocturnal diuresis 90 mL/h or higher (NUP90). The mean patient age was 71 years (45-86, sex ratio 33/30). On average, patients were diagnosed for IPD 6.76 years earlier. The prevalence of NP was 64.5% according to NUV33 definition, and 17.7% according to NUP90 definition. Among patients with nocturia, the prevalence of NP was 66% (NUV33) and 21.5% (NUP90). No association was observed between disease duration of the IPD and the prevalence of nocturia and NP. Patients 70 years and older were more likely to have NP as defined by NUV33 than those less than 70 years (72.7% versus 55.17%, P=0.015). Men had more frequently nocturia (33.3% versus 20.7%, P=0.027). The prevalence of NP and nocturia was analyzed in patients with IPD at a non-severe stage. This prevalence was not higher than in the general population of the same age. The mechanism of nocturia in patients with IPD is not unambiguous and therefore requires to be explored by a bladder diary. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

A subset of frequent users of emergency services are those who use the emergency department (ED) for acute alcohol intoxication. This population and their ED encounters have not been previously described. This was a retrospective, observational, cohort study of patients presenting to the ED for acute alcohol intoxication between 2012 and 2016. We collected all data from the electronic medical record. Frequent users for alcohol intoxication were defined as those with greater than 20 visits for acute intoxication without additional medical chief complaints in the previous 12 months. We used descriptive statistics to evaluate characteristics of frequent users for alcohol intoxication, as well as their ED encounters. We identified 32,121 patient encounters. Of those, 325 patients were defined as frequent users for alcohol intoxication, comprising 11,370 of the encounters during the study period. The median maximum number of encounters per person for alcohol intoxication in a one-year period was 47 encounters (range 20 to 169). Frequent users were older (47 years vs. 39 years), and more commonly male (86% vs. 71%). Frequent users for alcohol intoxication had higher rates of medical and psychiatric comorbidities including liver disease, chronic kidney disease, ischemic vascular disease, dementia, chronic obstructive pulmonary disease, history of traumatic brain injury, schizophrenia, and bipolar disorder. In this study, we identified a group of ED frequent users who use the ED for acute alcohol intoxication. This population had higher rates of medical and psychiatric comorbidities compared to non-frequent users.

[Would the Screening of Common Mental Disorders in Primary-Care Health Services Hyper-Frequent Patients Be Useful?].

Hyper-frequentation in health services is a problem for patients, their families and the institutions. This study is aimed at determining the frequency and characteristics of common mental disorders in hyper-frequent patients showing vague symptoms and signs at a primary healthcare service during the year 2007 in the city of Cali (Colombia). Cross sectional. The most frequent mental disorders in hyper-frequent patients were detected through a telephone interview which included several modules of the PRIME MD instrument. In general, healthcare service hyper-frequenters are working women, 38,7-year old in average. Basically, the consultation is due to cephalalgia but they also exhibit a high prevalence of common mental disorders (somatization, depression and anxiety) not easily diagnosed by physicians in primary care. Expenses for additional health activities generated by these patients are attributed basically to medical consultation and required procedures. Considering hyper-frequenters in health care services as a risk group in terms of common mental disorders involves screening as an efficient strategy to prevent abuse in service use and to improve satisfaction with the attention received.

Dysphagia is the difficulty in swallowing and is often described by the patients as a 'perception' that there is an impediment to the normal passage of the swallowed material. It is frequently observed that there is an association of dysphagia with serious underlying disorders and warrants early evaluation. The current study aimed to determine the frequency of common endoscopic findings in patients presenting with oesophageal dysphagia. This cross-sectional descriptive study was carried out in the department of Gastroenterology, Ayub Medical College, Abbottabad, from October 2012 to April 2013. Consecutive patients with dysphagia were included in the study and were subjected to endoscopy. A total of 139 patients presenting with dysphagia were studied, 81 (58.3%) were males and 58 (41.7%) were females. The mean age was 52.41 ± 16.42. Malignant oesophageal stricture was the most common finding noted in 38 (27.3%) patients with 28 (73.7%) males and 23 (60.5%) patients among them were above the age of 50 years. It was followed by normal upper Gastrointestinal (GI) endoscopy in 29 (20.9%) patients and reflux esophagitis in 25 (18.0%) patients. Schatzki's ring was present in 14 (10.1%) patients; benign oesophageal strictures in 12 (8.6%) patients while achalasia was noted in 7 (5.0%) patients. 14(10.1%) patients had findings other than the ones mentioned above. Malignancies are a more common cause of dysphagia in our population and early diagnosis can result in proper treatment of many of these cases.

We hypothesized that medication adherence is affected by the number of pharmacies a patient frequents. The objective was to estimate the strength of association between the number of pharmacies a patient frequents and adherence to statins. Using administrative data from the Nova Scotia Seniors' Pharmacare program, a retrospective cohort study was conducted among subjects aged 65 years and older first dispensed statin between 1998 and 2008. The Usual Provider of Care (UPC), was defined as the number of dispensation days from the most frequented pharmacy divided by the total number of dispensation days. Estimated adherence of over 80% of the Medication Possession Ratio was defined as adherent. Data were analyzed using hierarchical linear regression. The cohort of 25,641 subjects was 59% female with a mean age of 74 years. During follow-up, subjects filled prescriptions in a median of 2 (mean = 2; standard deviation = 0.88) pharmacies and visited pharmacies a median of 28 (mean = 30) times. During that time, 61% of patients used one pharmacy exclusively. Among subjects using 1 pharmacy, 59% were adherent while 58% using more than one pharmacy were adherent. However, upon adjustment for differences in distributions of age, sex, and other confounders, subjects who used more than one pharmacy had 10% decreased odds of statin adherence (odds ratio: 0.90, 95% confidence interval: 0.86-0.96). These results were robust in sensitivity analyses. Among seniors newly starting statin therapy, using a single community pharmacy was modestly associated with adherence.

Bringing stability to the COPD patient: clinical and pharmacological considerations for frequent exacerbators

Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are critical events associated with accelerated loss of lung function, increased morbidity, and excess mortality. AECOPD are heterogeneous in nature and this may directly impact clinical decision making, specifically in patients with frequent exacerbations. A “frequent exacerbator” is a sub-phenotype of COPD that is defined as an individual who experiences ≥2 moderate to severe exacerbations per year. This distinct subgroup has higher mortality and account for more than half of COPD-related hospitalizations annually. Thus, it is imperative to identify individuals at risk for frequent exacerbations and choose optimal strategies to minimize risk for these events. New paradigms for utilizing combination inhalers and the introduction of novel oral compounds provide expanded treatment options to reduce the risk and frequency of exacerbations. The goals of managing frequent exacerbators or patients at risk for AECOPD are: 1) maximizing bronchodilation, 2) reducing inflammation, and 3) targeting specific molecular pathways implicated in COPD and AECOPD pathogenesis. Novel inhaler therapies include combination long acting muscarinic agents (LAMA) plus long acting beta agonists (LABA) show promising results compared to monotherapy or LABA inhaled corticosteroid (ICS) combination in reducing exacerbation risk among individuals at risk for exacerbations and among frequent exacerbators. Likewise, oral medications including macrolides and phosphodiesterase (PDE4) inhibitors reduce the risk for AECOPD in select groups of individuals at high risk for exacerbation. Future direction in COPD management is based on identification of various subtypes or “endotypes” and targeting therapies based on their pathophysiology. This review aims to describe the impact of AECOPD, challenges posed by frequent exacerbators, and explores the rationale for different pharmacologic approaches to preventing AECOPD in these

Asymmetrical knowledge claims in general practice consultations with frequently attending patients: limitations and opportunities for patient participation.

Ariss, Steven M

2009-09-01

Asymmetry of knowledge does not simply relate to knowing or not knowing. Participants in consultations also display normative entitlements to knowledge which are related to their identities in the interaction. Claims of entitlement to knowledge are oriented to by the other participant as either straightforwardly acceptable or problematic. Thus research has shown that asymmetry in doctor-patient interactions is collaboratively achieved. Whilst the asymmetry of medical consultations has long been recognised, understanding asymmetry in the context of patient participation is becoming an increasingly important priority. This paper is not concerned with potential benefits or the feasibility of increasing patient participation in general practice (GP) consultations. Rather it seeks to describe specific limitations and opportunities for the participation of patients regarding the discussion of their problems, treatments and management of illness. Using Conversation Analysis this paper investigates GP consultations with frequently attending patients in the UK. It describes how the moral dimensions of epistemic authority constrain the different conversational resources available to GPs and patients. Findings suggest that in maintaining asymmetrical claims to knowledge debate is foregone in favour of efficient progression through the phases of the interaction. Thus interactions militate against the discussion of areas where alignment of perspectives might be lacking and participants do not pursue actions which might lead towards claiming a greater understanding of each others' point of view. However, there are aspects of consultations with frequently attending patients which display reduced asymmetry with regard to participants' claims to epistemic authority.

Genitourinary tuberculosis - a rare presentation of a still frequent infection in renal transplant recipients

Directory of Open Access Journals (Sweden)

Natacha Jardim Rodrigues

Full Text Available Abstract Mycobacterium tuberculosis infection in renal transplant recipients is associated with significant morbidity and mortality. Genitourinary tuberculosis is a less frequent presentation and a high level of suspicion is needed to avoid treatment delay. Management is challenging due to the interaction of calcineurin inhibitors with antituberculous medications and the known side effects of these drugs, with higher prevalence in this population. The authors present a case of a renal transplant recipient with urinary and constitutional symptoms whom is diagnosed with tuberculosis after a prostatic biopsy in an already disseminated stage and develops hepatotoxicity to antituberculous therapy.

Hereditary motor and sensory neuropathy type Russe (HMSNR), also called CMT4G, is an autosomal recessive inherited peripheral neuropathy (IPN) caused by a founder mutation in the HK1 gene. HMSNR affects only patients with Roma origin, similar to the better known HMSN type Lom clarified earlier. By testing IPN patients with Roma origin, we realized that HMSNR affects surprisingly many patients in the Czech Republic. HMSNR is one of the most frequent types of IPN in this country and appears to be twice more frequent than HMSNL. Pronounced lower limb atrophies and severe deformities often lead to walking inability in even young patients, but hands are usually only mildly affected even after many years of disease duration. The group of 20 patients with HMSNR presented here is the first report about the prevalence of HMSNR from central Europe. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

In recent years, traditional diets enriched with fresh plant-based foods have been gradually abandoned, increasing the consumption of animal foods and highly processed food. The aim of this study was to assess the effects of a nutritional intervention with a Traditional Mediterranean Diet in patients with recurring colds (RC) and frequent inflammatory complications (IC). Prospective before-after comparison study of 63 girls and 65 boys aged 1-5 years were included over a year in the nutritional programme "Learning to eat from the Mediterranean". We studied clinical and therapeutic variables and various anthropometric parameters. All the studied indicators (number of catarrhal episodes CB, degree of intensity, emergency and hospital admissions) showed a positive and statistically significant evolution, evidenced from the first weeks of starting treatment, until the end of the year, after which 53.9% of patients had no CB, 25% had only one, and 16.4% had two episodes, compared to the 4.64 episodes on average in the previous year. Antibiotic use decreased by 87.4%, from 3.85±1.27 times/patient/year to 0.49±0.79 (pMediterranean Diet, increased from 7.8 to 10.9 points. The adoption of a Traditional Mediterranean Diet could be a major contribution to the improvement of patients with recurring colds and frequent inflammatory complications. Copyright © 2016 SEICAP.

p.Cys282Tyr (C282Y) homozygosity explains most cases of HFE-related hemochromatosis, but a significant number of patients presenting with typical type I hemochromatosis phenotype remain unexplained. We sought to describe the clinical relevance of rare HFE variants in non-C282Y homozygotes. Patients referred for hemochromatosis to the National Reference Centre for Rare Iron Overload Diseases from 2004 to 2010 were studied. Sequencing was performed for coding region and intronic flanking sequences of HFE, HAMP, HFE2, TFR2, and SLC40A1. Nine private HFE variants were identified in 13 of 206 unrelated patients. Among those, five have not been previously described: p.Leu270Argfs*4, p.Ala271Valfs*25, p.Tyr52*, p.Lys166Asn, and p.Asp141Tyr. Our results show that rare HFE variants are identified more frequently than variants in the other genes associated with iron overload. Rare HFE variants are therefore the most frequent cause of hemochromatosis in non-C282Y homozygote HFE patients. Am. J.

Full Text Available Integrative veterinary medicine, the combination of complementary and alternative therapies with conventional care, is increasingly prevalent in veterinary practice and a focus of clinical instruction in many academic teaching institutions. However, the presenting complaints, therapeutic modalities, and patient population in an integrative medicine service have not been described. A retrospective analysis of 5,195 integrative patient treatment sessions in a veterinary academic teaching hospital demonstrated that patients most commonly received a combination of therapeutic modalities (39% of all treatment sessions. The 274 patients receiving multiple modalities were most frequently treated for neurologic and orthopedic disease (50.7% versus 49.6% of all presenting complaints, resp.. Older neutered or spayed dogs (mean age = 9.0 years and Dachshunds were treated more often than expected based on general population statistics. Acupuncture, laser therapy, electroacupuncture, and hydrotherapy were frequently administered (>50% patients. Neurologic patients were more likely to receive acupuncture, electroacupuncture, and therapeutic exercises but less likely than orthopedic patients to receive laser, hydrotherapy, or therapeutic ultrasound treatments (P<0.05. The results suggest that the application of these specific modalities to orthopedic and neurologic diseases should be subjected to increased evidence-based investigations. A review of current knowledge in core areas is presented.

The objective of the present study was to investigate whether mild cognitive deficits are present in patients with heart failure (HF) despite absence of any known cognitive disorder. A well defined group of patients (n = 40) with heart failure completed a cognitive screening check list, a depression screening questionnaire, and a battery consisting of neuropsychological tests assessing 5 different cognitive domains: speed/attention, episodic memory, visuospatial functions, language, and executive functions. The neuropsychological results were compared with those from a group of healthy control subjects (n = 41). The patients with HF displayed cognitive impairment compared with the control group within the domains speed and attention, episodic memory, visuospatial functions, and language. Among them, 34 HF patients (85%) could be classified with mild cognitive impairment (MCI), the majority as nonamnestic MCI, ie, with no memory impairment. Considering the high occurrence of mild cognitive deficits among HF patients without known cognitive disorders, closer attention should be paid to their self-care and compliance. Inadequate self-care and compliance could lead to more frequent hospitalizations. Furthermore, the HF patients may be at increased risk of dementia. Copyright © 2015 Elsevier Inc.

The nonspecific clinical presentation of pulmonary embolism (PE) frequently leads to delay in its diagnosis. This study aimed to assess the impact of delay in presentation on the diagnostic management and clinical outcome of patients with suspected PE. In 4,044 consecutive patients with suspected PE, patients presenting more than 7 days from the onset of symptoms were contrasted with those presenting within 7 days as regards the safety of excluding PE on the basis of a clinical decision rule combined with D-dimer testing. Patients were followed for 3 months to assess the rates of recurrent venous thromboembolism and mortality. A delayed presentation (presentation >7 d) was present in 754 (18.6%) of the patients. The failure rate of an unlikely clinical probability and normal D-dimer test was 0.5% (95% confidence interval [CI], 0.01-2.7) for patients with and 0.5% (95% CI, 0.2-1.2) for those without diagnostic delay. D-dimer testing yielded a sensitivity of 99% (95% CI, 96-99%) and 98% (95% CI, 97-99%) in these groups, respectively. Patients with PE with diagnostic delay more frequently had centrally located PE (41% vs. 26%; P presentation. PE can be safely excluded based on a clinical decision rule and D-dimer testing in patients with a delayed clinical presentation. A delayed presentation for patients who survived acute PE was associated with a more central PE location, although this did not affect the clinical outcome at 3 months.

Frequent Symptom Sets Identification from Uncertain Medical Data in Differentially Private Way

2017-01-01

Full Text Available Data mining techniques are applied to identify hidden patterns in large amounts of patient data. These patterns can assist physicians in making more accurate diagnosis. For different physical conditions of patients, the same physiological index corresponds to a different symptom association probability for each patient. Data mining technologies based on certain data cannot be directly applied to these patients’ data. Patient data are sensitive data. An adversary with sufficient background information can make use of the patterns mined from uncertain medical data to obtain the sensitive information of patients. In this paper, a new algorithm is presented to determine the top K most frequent itemsets from uncertain medical data and to protect data privacy. Based on traditional algorithms for mining frequent itemsets from uncertain data, our algorithm applies sparse vector algorithm and the Laplace mechanism to ensure differential privacy for the top K most frequent itemsets for uncertain medical data and the expected supports of these frequent itemsets. We prove that our algorithm can guarantee differential privacy in theory. Moreover, we carry out experiments with four real-world scenario datasets and two synthetic datasets. The experimental results demonstrate the performance of our algorithm.

The progressive supra-nuclear paralysis (PSP) or Steele-Richardson-Olszewsky’s syndrome is a strange, degenerative illness produced by the deterioration and gradual death of brain selected areas. We present the case of a female patient, aged 80 years, who refers postural instability, frequent falls and cognitive dysfunctions. She also presents stiffness in retrocollis in the back of the neck, fall of eyelids, left hand shaking, dysarthric and incoherent language, and shaking of both hands in coins counting. The cardiovascular examination showed 2nd increased beat, systolic murmur III/IV in mitral focus, AT 160/90 mm of Hg, edemas in both inferior members, hearth frequency of 110 beats/min., and jugular ingurgitation. The rest of the physical examination was normal. The etiologic diagnosis was progressive supranuclear paralysis and dilated cardiomyopathy. The tau protein is important in the maintenance of the neuronal morphology through microtubules formation, the different proportions and locations, causing the Richardson’s syndrome. The most common symptoms of this entity are postural instability and frequent falls, dysarthria, hypokinesia and visual alterations. Magnetic resonance and functional neuroimaging help the diagnosis.

The clinical significance of prolonged PR interval has not been evaluated in patients with frequent premature atrial contractions (PACs). We investigated whether prolonged PR interval could predict new occurrence of atrial fibrillation (AF) in patients with frequent PACs. We retrospectively analyzed 684 patients with frequent PACs (> 100 PACs/day) who performed repeated 24-hour Holter monitoring. Prolonged PR interval was defined as longer than 200 msec. Among 684 patients, 626 patients had normal PR intervals (group A) and 58 patients had prolonged PR intervals (group B). After a mean follow-up of 59.3 months, 14 patients (24.1%) in group B developed AF compared to 50 patients (8.0%) in group A (P PR interval (hazard ratio [HR], 1.950; 95% CI, 1.029-3.698; P = 0.041), age (HR, 1.033; 95% CI, 1.006-1.060; P = 0.015), and left atrial (LA) dimension (HR, 1.061; 95% CI, 1.012-1.112; P = 0.015) were associated with AF occurrence. Prolonged PR interval, advanced age, and enlarged LA dimension are independent risk factors of AF occurrence in patients with frequent PACs.

Road traffic injuries kill more people in India than in any other country in the world, and these numbers are rising with increasing population density and motorization. Official statistics regarding road traffic injuries are likely subject to underreporting. This study presents results of a surveillance program based at a public tertiary hospital in Hyderabad, India. All consenting patients who presented to the casualty ward after a road traffic injury over a 9-month period were enrolled. Interviews were performed and data abstracted from clinical records by trained research assistants. Data included demographics, injury characteristics, risk factors, safety behaviors, and outcomes. A total of 5,298 patients were enrolled; their mean age was 32.4 years (standard deviation 13.8) and 87.3% were men; 58.2% of patients were injured while riding a motorcycle or scooter, 22.5% were pedestrians, and 9.2% used motorized rickshaws. The most frequent collision type was skid or rollover (40.9%). Male victims were younger than female victims and were overrepresented among motorized 2-wheeler users. Patients were most frequently injured from 1600 to 2400. A total of 27.3% of patients were admitted. Hospital mortality was 5.3%, and 48.2% of deaths were among motorized 2-wheeler users. This is one of the few prospective, hospital-based studies of road traffic injury epidemiology in India. The patient population in this study was similar to prior hospital-based studies. When compared to government surveillance systems, this study showed motorized 2-wheeler users to be more frequently represented among the overall population and among fatalities. Further research should be done to develop interventions to decrease mortality associated with 2-wheeled vehicles in India. Copyright © 2017. Published by Elsevier Inc.

Chest computed tomography (CT) findings of nodules, ground glass opacities, and consolidations are often interpreted as representing invasive fungal infection in individuals with febrile neutropenia. We assessed whether these CT findings were present in asymptomatic individuals with acute myeloid leukemia (AML) at low risk of invasive fungal disease. A retrospective study of consecutive asymptomatic adult patients with newly diagnosed AML over a 2-year period was performed at a tertiary care oncology center. Radiology reports of baseline chest CTs were reviewed. Of 145 CT scans, the majority (88%) had pulmonary abnormalities. Many (70%) had one or both of unspecified opacities (52%) and nodules (49%). Ground glass opacities (18%) and consolidations (12%) occurred less frequently. Radiologists suggested pneumonia as a possible diagnosis in 32% (n = 47) of scans. Chest CT may result in over-diagnosis of invasive fungal disease in individuals with febrile neutropenia if interpreted without correlation to the patients' clinical status.

Early detection of pancreatic and periampullary neoplasms is critical to improve their clinical outcome. The present authors previously demonstrated that DNA hypermethylation of adenomatous polyposis coli (APC), histamine receptor H2 (HRH2), cadherin 13 (CDH13), secreted protein acidic and cysteine rich (SPARC) and engrailed-1 (EN-1) promoters is frequently detected in pancreatic tumor cells. The aim of the present study was to assess their prevalence in pancreatic juice of carcinomas of the pancreas and periampullary area. A total of 135 pancreatic juices obtained from 85 pancreatic cancer (PC), 26 ampullary carcinoma (AC), 10 intraductal papillary mucinous neoplasm (IPMN) and 14 chronic pancreatitis (CP) patients were analyzed. The methylation status of the APC, HRH2, CDH13, SPARC and EN-1 promoters was analyzed using methylation specific-melting curve analysis (MS-MCA). Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations were also tested with allele-specific quantitative polymerase chain reaction amplification. Out of the 5 promoters analyzed, APC (71%) and HRH2 (65%) were the most frequently methylated in PC juice. APC methylation was also detected at a high frequency in AC (76%) and IPMN (80%), but only occasionally observed in CP (7%). APC methylation had a high sensitivity (71-80%) for all types of cancer analyzed. The panel (where a sample scored as positive when ≥2 markers were methylated) did not outperform APC as a single marker. Finally, KRAS detection in pancreatic juice offered a lower sensitivity (50%) and specificity (71%) for detection of any cancer. APC hypermethylation in pancreatic juice, as assessed by MS-MCA, is a frequent event of potential clinical usefulness in the diagnosis of pancreatic and periampullary neoplasms.

We used a hospital computer to identify 50 patients (35 women, 15 men) satisfying research criteria for "frequent attenders" at a gastroenterology outpatient clinic (four or more visits to a general hospital clinic in the previous 12 months). Their mean duration of symptoms was 5 years, and 80% reported fatigue as a significant complaint. Thirteen (37%) of the women were also consulting a gynecologist, and in nine of these their status was normal. Seven (21%) of the 35 women who were interviewed had a history of childhood sexual abuse, and these patients reported significantly more lifetime somatic symptoms (9.7, SD = 3.8) than those without such a history (5.4, SD = 3.5, p = 12 visits over the previous 12 months), and the patients reported a mean number of 5.7 (SD = 2.1) specialist appointments in the previous year. There may be a case for using the hospital computer to identify frequent attenders proactively at an earlier stage of their hospital visits so that appropriate management can be instituted. If such patients can be identified in this way, their assessment and management might be more appropriately supervised in designated clinics by more experienced gastroenterology staff.

To evaluate the incidence of unexplained falls in elderly patients affected by fall-related fractures admitted to orthopaedic wards, we recruited 246 consecutive patients older than 65 (mean age 82 ± 7 years, range 65-101). Falls were defined "accidental" (fall explained by a definite accidental cause), "medical" (fall caused directly by a specific medical disease), "dementia-related" (fall in patients affected by moderate-severe dementia), and "unexplained" (nonaccidental falls, not related to a clear medical or drug-induced cause or with no apparent cause). According to the anamnestic features of the event, older patients had a lower tendency to remember the fall. Patients with accidental fall remember more often the event. Unexplained falls were frequent in both groups of age. Accidental falls were more frequent in younger patients, while dementia-related falls were more common in the older ones. Patients with unexplained falls showed a higher number of depressive symptoms. In a multivariate analysis a higher GDS and syncopal spells were independent predictors of unexplained falls. In conclusion, more than one third of all falls in patients hospitalized in orthopaedic wards were unexplained, particularly in patients with depressive symptoms and syncopal spells. The identification of fall causes must be evaluated in older patients with a fall-related injury.

To investigate the association between the quality of the family physician-patient relationship and frequent attendance of primary and specialist health care. Cross-sectional survey of a representative German population sample (N=2.266). Family physician-patient relationship was assessed with the Patient Doctor Relationship Questionnaire (PDRQ-9). Determinants of frequent attendance were analyzed using logistic regression. Frequent attendance of family physicians was associated with lower income (OR 1.43, 95% CI 1.02-2.00), not being in paid work (OR 1.58, CI 1.08-2.30), psychological distress (OR 1.14, CI 1.07-1.22), somatic symptoms (OR 1.07, CI 1.04-1.11), and physical comorbidity (OR 1.54, CI 1.36-1.74) in the multivariate analysis. Frequent attendance of specialists was related to psychological distress (OR 1.12, CI 1.04-1.20), somatic symptoms (OR 1.08, CI 1.04-1.11), and physical comorbidity (OR 1.69, CI 1.48-1.93) in the multivariate analysis. Quality of the relationship was associated with frequent attendance only in the univariate analyses. A stronger relationship with the family physician was not associated with reduced contact with specialists. The quality of the family physician-patient relationship is not independently associated with frequent attendance. Family physicians should be aware that need factors, i.e. symptom burden and physical comorbidities, are main drivers of frequent attendance. Copyright © 2016 Elsevier Ireland Ltd.

Osteopathic manipulative therapy (OMTh; manipulative care provided by foreign-trained osteopaths) may be used for managing headache pain and related disability, but there is a need for high-quality randomized controlled trials to assess the effectiveness of this intervention. To explore the efficacy of OMTh for pain management in frequent episodic tension-type headache (TTH). Single-blind randomized placebo-controlled pilot study. Patients were recruited from 5 primary care settings. Forty-four patients who were affected by frequent episodic TTH and not taking any drugs for prophylactic management of episodic TTH were recruited. Patients were randomly allocated to an experimental or control group. The experimental group received corrective OMTh techniques, tailored for each patient; the control group received assessment of the cranial rhythmic impulse (sham therapy). The study included a 1-month baseline period, a 1-month treatment period, and a 3-month follow-up period. The primary outcome was the change in patient-reported headache frequency, and secondary outcomes included changes in headache pain intensity (discrete score, 1 [lowest perceived pain] to 5 [worst perceived pain]), over-the-counter medication use, and Headache Disability Inventory score. Forty patients completed the study (OMTh, n=21; control, n=19). The OMTh group had a significant reduction in headache frequency over time that persisted 1 month (approximate reduction, 40%; Ptreatment. Moreover, there was an absolute difference between the 2 treatment groups at the end of the study, with a 33% lower frequency of headache in the OMTh group (Ptreatment modalities and may benefit patients who have adverse effects to medications or who have difficulty complying with pharmacologic regimens.

Purpose: To retrospectively review the outcome of conservatively treated breast cancer patients who present with nipple discharge at initial diagnosis. Methods and Materials: The charts of 1097 patients undergoing conservative surgery and radiation therapy between January 1970 and December 1990 were reviewed. All patient data, including clinical, pathologic, treatment, and outcome variables were entered onto a computerized database. For the current study, specific attention was directed to the initial presenting symptoms and patients were divided into two groups: those presenting at initial diagnosis with nipple discharge (D/C-YES, n = 17), and those presenting without nipple discharge (D/C-NO, n = 1080). Results: As of August 1998, with a median follow-up of 12 years, the 10-year actuarial survival, distant metastasis-free survival, and breast relapse-free survival rates for the overall population were 73%, 78%, and 83%, respectively. Although the D/C-YES and D/C-NO groups were well balanced with respect to the majority of clinical factors, the D/C-YES patients had a higher percentage of DCIS histology (7.3% vs 1.2%, p < 0.01), were less likely to undergo reexcision (12% vs 35%), and were more frequently under age 40 (35% vs 12%) than the D/C-NO patients. Over the time span of this study, status of the final surgical margin was indeterminate in the majority of cases. Local relapses occurred in 6 of the 17 patients in the D/C-YES group, resulting in a 10-year actuarial breast relapse-free survival rate of 50%, which was significantly lower than the 10-year breast relapse-free survival rate of 86% in the D/C-NO population. Among the patients presenting with nipple discharge, those with sacrifice of the nipple areolar complex had a lower local relapse rate than those patients who had conservation of the nipple areolar complex (20% vs 42%), although this difference did not reach statistical significance. Conclusions: Although patients presenting with nipple discharge

Celiac disease (CD) may have a variety of different presentations. This study has aimed to explore the prevalence of gastrointestinal (GI) and non-GI symptoms in patients with CD according to data collected in Italy and Romania (Europe) and Iran (Middle East). This is a retrospective cross-sectional study conducted in Iran, Romania and Italy with data collection during the period from May 2009 - May 2011. For each center we included only patients with CD that was confirmed by endoscopy, small bowel biopsies and positive serology. GI symptoms such as abdominal pain, diarrhea, constipation, nausea and vomiting, weight loss and flatulence, as well as additional signs and symptoms of iron deficiency anemia (IDA), osteoporosis, hypertransaminasemia, and other related abnormalities were collected. Overall, 323 women and 127 men, whose mean age at diagnosis was 34.2 ± 16.47 years were included in this study. Of these, 157 subjects (34.9%) reported at least one GI symptom. The majority of cases had the following primary presenting GI symptoms: diarrhea (13.6%), dyspepsia and constipation (4.0%). Other disease symptoms were reported by 168 (37.3%) patients. The most presenting non-GI symptoms in the majority of cases were anemia (20.7%) and osteopenia (6%). There were statistically significant differences between the majority of symptoms when we compared the reported clinical symptoms from different countries. This study indicated that upper abdominal disorders such as abdominal pain and dyspepsia were the most common primary complaints among European patients, whereas Iranian patients had complaints of diarrhea and bloating as the classic presentations of CD. For non-GI symptoms, anemia was the most frequent complaint for both Iranian and Italian patients; however it was significantly higher in Iranians.

Sporotrichosis is a subcutaneous mycosis caused by Sporothrix sp., a dimorphic fungus. Although the cutaneous form is the most frequent form, the ocular presentation has been increasingly diagnosed in epidemic areas. We describe three cases of ocular sporotrichosis with the involvement of the ocular adnexa due to autoinoculation without trauma with successful antifungal treatment. Patient 1: A 68-year-old woman presented with granulomatous conjunctivitis of the right eye with an ulcerated nodule on the right temporal region for 5 months. Patient 2: A 46-year-old woman with conjunctival hyperemia of the left eye with associated periorbital edema and erythema for the past 4 months was referred to the Dermatology Department due to an ulcerated nodule on the left malar region. Patient 3: A 14-year-old boy presented to the emergency department with inferior palpebral edema with a 5-day evolution. Specimens were obtained from the lesions of the three patients, and the cultures were positive for Sporothrix sp. The three cases were diagnosed as ocular sporotrichosis and were successfully treated with itraconazole (200-400 mg/d). Two of the three patients developed sequelae such as conjunctival fibrosis and symblepharon. We emphasize the importance of the ophthalmologist being familiar with the diagnosis and management of this rare and frequently misdiagnosed form of sporotrichosis.

Mutations in the TMEM70 are the most common cause of nuclear ATP synthase deficiency resulting in a distinctive phenotype characterized by severe neonatal hypotonia, hypertrophic cardiomyopathy (HCMP), facial dysmorphism, severe lactic acidosis, hyperammonemia and 3-methylglutaconic aciduria (3-MGA). We collected 9 patients with genetically confirmed TMEM70 defect from 8 different families. Six were homozygous for the c.317-2A>G mutation, 2 were compound heterozygous for mutations c.317-2A>G and c.628A>C and 1 was homozygous for the novel c.701A>C mutation. Generalized hypotonia, lactic acidosis, hyperammonemia and 3-MGA were present in all since birth. Five patients presented acute respiratory distress at birth requiring intubation and ventilatory support. HCMP was detected in 5 newborns and appeared a few months later in 3 additional children. Five patients showed a severe and persistent neonatal pulmonary hypertension (PPHN) requiring Nitric Oxide (NO) and/or sildenafil administration combined in 2 cases with high-frequency oscillatory (HFO) ventilation. In 3 of these patients, echocardiography detected signs of HCMP at birth. PPHN is a life-threatening poorly understood condition with bad prognosis if untreated. Pulmonary hypertension has rarely been reported in mitochondrial disorders and, so far, it has been described in association with TMEM70 deficiency only in one patient. This report further expands the clinical and genetic spectrum of the syndrome indicating PPHN as a frequent and life-threatening complication regardless of the type of mutation. Moreover, in these children PPHN appears even in the absence of an overt cardiomyopathy, thus representing an early sign and a clue for diagnosis. Copyright © 2014 Elsevier Inc. All rights reserved.

Diabetes Is Associated with Worse Clinical Presentation in Tuberculosis Patients from Brazil: A Retrospective Cohort Study.

Directory of Open Access Journals (Sweden)

Leonardo Gil-Santana

Full Text Available The rising prevalence of diabetes mellitus (DM worldwide, especially in developing countries, and the persistence of tuberculosis (TB as a major public health issue in these same regions, emphasize the importance of investigating this association. Here, we compared the clinical profile and disease outcomes of TB patients with or without coincident DM in a TB reference center in Brazil.We performed a retrospective analysis of a TB patient cohort (treatment naïve of 408 individuals recruited at a TB primary care center in Brazil between 2004 and 2010. Data on diagnosis of TB and DM were used to define the groups. The study groups were compared with regard to TB disease presentation at diagnosis as well as to clinical outcomes such as cure and mortality rates upon anti-tuberculosis therapy (ATT initiation. A composite score utilizing clinical, radiological and microbiological parameters was used to compare TB severity between the groups.DM patients were older than non-diabetic TB patients. In addition, diabetic individuals more frequently presented with cough, night sweats, hemoptysis and malaise than those without DM. The overall pattern of lung lesions assessed by chest radiographic examination was similar between the groups. Compared to non-diabetic patients, those with TB-diabetes exhibited positive acid-fast bacilli in sputum samples more frequently at diagnosis and at 30 days after ATT initiation. Notably, higher values of the TB severity score were significantly associated with TB-diabetes comorbidity after adjustment for confounding factors. Moreover, during ATT, diabetic patients required more frequent transfers to TB reference hospitals for complex clinical management. Nevertheless, overall mortality and cure rates were indistinguishable between the study groups.These findings reinforce the idea that diabetes negatively impacts pulmonary TB severity. Our study argues for the systematic screening for DM in TB reference centers in endemic

Atrial fibrillation (AF) is associated with the autonomic nervous system (ANS), and fluctuation of autonomic tone is more prominent in patients with AF. As autonomic tone affects the heart rate (HR), and there is an inverse relationship between HR and PR interval, PR interval variation could be greater in patients with AF than in those without AF. The purpose of this study was to investigate the correlation between PR interval variation and new-onset AF in patients with frequent PACs.We retrospectively enrolled 207 patients with frequent PACs who underwent electrocardiographs at least 4 times during the follow-up period. The PR variation was calculated by subtracting the minimum PR interval from the maximum PR interval. The outcomes were new occurrence of AF and all-cause mortality during the follow-up period.During a median follow-up of 8.3 years, 24 patients (11.6%) developed new-onset AF. Univariate analysis showed that prolonged PR interval (PR interval > 200 ms, P = 0.021), long PR variation (PR variation > 36.5 ms, P = 0.018), and PR variation (P = 0.004) as a continuous variable were associated with an increased risk of AF. Cox regression analysis showed that prolonged PR interval (hazard ratio = 3.321, 95% CI 1.064-10.362, P = 0.039) and PR variation (hazard ratio = 1.013, 95% CI 1.002-1.024, P = 0.022) were independent predictors for new-onset AF. However, PR variation and prolonged PR interval were not associated with all-cause mortality (P = 0.465 and 0.774, respectively).PR interval variation and prolonged PR interval are independent risk factors for new-onset AF in patients with frequent PACs. However we were unable to determine a cut-off value of PR interval variation for new-onset AF.

To determine the demographic and clinical data of primary tumors of the lacrimal sac presenting as lacrimal obstruction. Retrospective and descriptive study was conducted between the years 2007 to 2012 on all patients undergoing surgery for low lacrimal obstruction at Dr. Luis Sanchez Bulnes Hospital, an Association for the prevention of blindness in Mexico IAP. Primary tumors of the lacrimal sac represented 2.5% of all lacrimal obstructions, being more common in women than in men (8:1). The large majority (89%) of the cases were non-epithelial, with lymphoid lesions being the most frequent. Benign tumors were presented at a younger age (50 years old) than malignant (70 years old). One-third (33%) of cases were unexpected findings during surgery (100% benign). Just over half (55%) were malignant tumors (1.4% of obstructions), all of them lymphoproliferative lesions. The most frequent clinical tumor was in the inner edge, either with or without epiphora. The progression time varied according to the degree of aggressiveness of the lymphoma (3 months-10 years). Lacrimal sac tumors are rare, but they must be taken into account in patients with an unusual clinical presentation of lacrimal obstruction. Copyright © 2013 Sociedad Española de Oftalmología.

Eighty-one patients with diagnostically difficult clinical presentations suggesting coronary disease underwent symptom-limited maximal-exercise treadmill testing (ETT) and exercise radionuclide scanning with 201 Tl. Results of these tests were in agreement in only 47 percent of the cases. Either exercise thallium or ETT was positive in 94 percent of patients with disease. Among a population with a disease prevalence of 67 percent, agreement between exercise thallium an ETT predicted disease in 92 percent of instances or excluded disease in 82 percent of instances. Frequent discordance between these two tests in 53 percent of the cases unfortunately limits this usefulness

Vincristine (VCR) induced peripheral neuropathy is a common complication in children with acute lymphoblastic leukemia (ALL). A retrospective data analysis over an interval of 10 years (2006-2016) of all children with ALL seen at Sultan Qaboos University Hospital was carried out. Electronic medical records of eligible patients were reviewed. Patients with clinical evidence of neuropathy and abnormal nerve conduction studies (NCSs) were included in the study. Nineteen (nine females and 10 males) out of 103 pediatric patients developed VCR-related neuropathy, and their age ranged between 2.5 and 14 years. Symptoms started after 2-11 doses of VCR. All 19 patients had documented peripheral neuropathy on NCSs. The autonomic nervous system and cranial nerves affection was relatively common in our patients; two presented with bradycardia, two patients with unexplained tachycardia, and five had abdominal pain and constipation, complicated by typhlitis in two patients. One patient developed unilateral hearing loss. Two patients developed severe life-threatening cranial nerve involvement with bilateral ptosis and recurrent laryngeal nerve involvement presented as vocal cord paralysis, hoarseness of voice, frequent chocking, and aspiration episodes. Peripheral neuropathy was the commonest form of VCR-related neuropathy. Autonomic neuropathy was relatively common in our patients. Cranial neuropathy is a serious side effect of VCR that can be severe, involving multiple cranial nerves and needs prompt recognition and management. Concomitant administration of pyridoxine and pyridostigmine does not seem to protect against further neurological damage in some patients. © 2017 Wiley Periodicals, Inc.

1983-01-01

Eighty-one patients with diagnostically difficult clinical presentations suggesting coronary artery disease underwent symptom-limited maximal-exercise treadmill testing (ETT) and exercise radionuclide scanning with thallium-201 followed by coronary angiography. Results showed that in nearly half of the patients (47%) these tests were in agreement, while either exercise thallium or ETT was positive in 94% of patients with coronary artery disease. It was found that agreement between exercise thallium and ETT tests predicted disease in 92% of the instances or excluded disease in 82% of the instances. It is concluded that despite frequent discord between these two tests in 53% of the cases, a significant gain in exclusive diagnostic capability is realized when applied to a patient population anticipated to have a disease prevalence equal to the 67% encountered in this study

In spite of the high prevalence of suicide behaviours and the magnitude of the resultant burden, little is known about why individuals reattempt. We aim to investigate the relationships between clinical risk factors and the repetition of suicidal attempts. 1349 suicide attempters were consecutively recruited in the Emergency Room (ER) of two academic hospitals in France and Spain. Patients were extensively assessed and demographic and clinical data obtained. Data mining was used to determine the minimal number of variables that blinded the rest in relation to the number of suicide attempts. Using this set, a probabilistic graph ranking relationships with the target variable was constructed. The most common diagnoses among suicide attempters were affective disorders, followed by anxiety disorders. Risk of frequent suicide attempt was highest among middle-aged subjects, and diminished progressively with advancing age of onset at first attempt. Anxiety disorders significantly increased the risk of presenting frequent suicide attempts. Pathway analysis also indicated that frequent suicide attempts were linked to greater odds for alcohol and substance abuse disorders and more intensive treatment. Novel statistical methods found several clinical features that were associated with a history of frequent suicide attempts. The identified pathways may promote new hypothesis-driven studies of suicide attempts and preventive strategies. Copyright © 2010 Elsevier Ltd. All rights reserved.

Full Text Available Background/Aims: Colonoscopy and computed tomography (CT are used primarily to exclude organic diseases in patients with irritable bowel syndrome (IBS, rather than to assess the pathophysiology of IBS. We aimed to evaluate colonic dysmotility and morphology in Japanese patients with IBS.Methods: One hundred eighty-four patients with IBS and 49 asymptomatic controls who underwent colonoscopy in combination with CT colonography or barium enema were retrospectively reviewed between 2008 and 2012. Water-aided colonoscopy was performed without sedation by a single endoscopist. The duration and pattern of colonic movement and cecal intubation time were recorded. To assess colonic morphology, barium enema or CT colonography were performed immediately after colonoscopy.Results: Colonic dysmotility was more frequent in the IBS group (28.8% vs. 2.0% in controls, P<0.001, especially in cases of IBS with diarrhea (IBS-D (IBS with constipation [IBS-C] 28.8% vs. IBS-D 60.0% vs. mixed IBS [IBS-M] 5.1%, P<0.001. Colonic morphological abnormality was more frequent in the IBS group than in the control group (77.7% vs. 24.5%, P<0.001, especially in IBS-M and IBS-C groups (IBS-C 77.5% vs. IBS-D 48.9% vs. IBS-M 100%, P<0.001. Most patients with IBS with colonic dysmotility had experienced stress related to their symptoms. Cecal intubation time was significantly longer in the IBS group than in the control group (12.1±6.9 minutes vs. 4.6±1.9 minutes, P<0.001.Conclusions: Unsedated colonoscopy, combined with radiographic findings, can detect colonic dysmotility and morphological abnormality. Technical difficulties observed during cecal intubation may partially explain the pathophysiology of IBS.

This is a case report of myxedema coma secondary to amiodarone-induced hypothyroidism in a patient with severe congestive heart failure (CHF). To our knowledge and after reviewing the literature there is one case report of myxedema coma during long term amiodarone therapy. Myxedema coma is a life threatening condition that carries a mortality reaching as high as 20% with treatment. The condition is treated with intravenous thyroxine (T4) or intravenous tri-iodo-thyronine (T3). Patients with CHF on amiodarone may suffer serious morbidity and mortality from hypothyroidism, and thus may deserve closer follow up for thyroid stimulating hormone (TSH) levels. This case report carries an important clinical application given the frequent usage of amiodarone among CHF patients. The myriad clinical presentation of myxedema coma and its serious morbidity and mortality stresses the need to suspect this clinical syndrome among CHF patients presenting with hypotension, weakness or other unexplained symptoms.

Full Text Available Purpose: The present study aimed at clinical and pulmonary functions profiling of patients with chronic obstructive pulmonary disease (COPD to anticipate future exacerbations. Methods: The study included 80 COPD patients; 40 patients had ≥2 acute exacerbations during preceding 1 year (frequent exacerbation [FECOPD] group and 40 patients had <2 acute exacerbations during preceding 1 year (infrequent exacerbation [I-FECOPD] group. Clinical profile, sputum microbiology, blood gas analysis, spirometric indices, and diffusion capacity (transfer test variables were assessed. Groups' comparison was performed using an independent t-test for numeric scale parameters and Chi-square test for nominal parameters. Pearson's and Spearman's correlation coefficients were derived for numeric scale parameters and numeric nominal parameters, respectively. Multinomial logistic regression analysis was done using SPSS software. Results: FECOPD group contained younger patients than in I-FECOPD group although the difference was not statistically significant. There was no significant difference between two groups regarding smoking pack-years and duration of illness. FECOPD group had significantly more expectoration score and Modified Medical Research Council dyspnea scores. Cough score and wheeze score did not differ significantly between two groups. More patients in FECOPD group (12/40 vs. 4/40 had lower airway bacterial colonization. Arterial blood gas parameters were more deranged in FECOPD group. Spirometric indices (forced expiratory volume during 1st s as well as transfer test (both diffusing capacity for carbon monoxide and transfer coefficient of the lung values were significantly reduced in FECOPD group. Conclusions: The patients in FECOPD group had clinical, spirometric, and transfer test profiling suggestive of a severe COPD phenotype, the recognition will help in predicting future exacerbations and a better management.

Full Text Available Introduction. Frequent colonoscopy screenings are critical for early diagnosis of colon cancer in patients with acromegaly. Case Presentations. We performed a retrospective analysis of the incidental diagnoses of colon cancer from the ACCESS trial (ClinicalTrials.gov identifier: NCT01995734. Colon cancer was identified in 2 patients (4.5%. Case  1 patient was a 36-year-old male with acromegaly who underwent transsphenoidal surgery to remove the pituitary adenoma. After surgery, the patient underwent routine colonoscopy screening, which revealed a 40 mm tubular adenoma in the descending colon. A T1N1a carcinoma was surgically removed, and 1 of 22 lymph nodes was positive for metastatic disease, leading to a diagnosis of stage 3 colon cancer. Case  2 patient was a 50-year-old male with acromegaly who underwent transsphenoidal surgery to remove a 2 cm pituitary adenoma. The patient reported severe cramping and lower abdominal pain, and an invasive 8.1 cm3 grade 2 adenocarcinoma with signet rings was identified in the ascending colon and removed. Of the 37 lymph nodes, 34 were positive for the presence of tumor cells, and stage 3c colon cancer was confirmed. Conclusion. Current guidelines for colonoscopy screening at the time of diagnosis of acromegaly and at appropriate follow-up intervals should be followed.

To characterise older people who frequently use emergency departments (EDs) and compare patient outcomes with older non-frequent ED attenders. Retrospective comparative cohort study. Logistic regression modelling of patient characteristics and health service usage, comparing older frequent ED attenders (≥4 ED attendances in 12 months) to non-frequent ED attenders. Three Australian public hospital EDs, with a total of 143 327 emergency attendances in the 12 months. People aged ≥65 years attending the ED in financial year 2013/2014. The primary outcome was frequent ED use; secondary outcomes were ED length of stay, discharge destination from ED, hospital length of stay, re-presentation within 48 h, hospital readmission within 30 days and in-hospital mortality. Five percent of older people were frequent attenders (n = 1046/21 073), accounting for 16.9% (n = 5469/32 282) of all attendances by older people. Frequent ED attenders were more likely to be male, aged 75-84 years, arrive by ambulance and have a diagnosis relating to chronic illness. Frequent attenders stayed 0.4 h longer in ED (P < 0.001), were more likely to be admitted to hospital (69.2% vs 67.2%; P = 0.004), and had a 1 day longer hospital stay (P < 0.001). In-hospital mortality for older frequent ED attenders was double that of non-frequent attenders (7.0% vs 3.2%, P < 0.001) over 12 months. Older frequent ED attenders had more chronic disease and care needs requiring hospital admission than non-frequent attenders. A new approach to care planning and coordination is recommended, to optimise the patient journey and improve outcomes.

To assess the impact of on-admission heart rate (HR) in patients presenting with acute coronary syndrome (ACS). Data were collected retrospectively from the second Gulf Registry of Acute Coronary Events. Patients were divided according to their initial HR into: (I: < 60, II: 60-69, III: 70-79, IV: 80-89 and V: ≥ 90 bpm). Patients' characteristics and hospital and one- and 12-month outcomes were analyzed and compared. Among 7939 consecutive ACS patients, groups I to V represented 7%, 13%, 20%, 23.5%, and 37%, respectively. Mean age was higher in groups I and V. Group V were more likely males, diabetic and hypertensive. ST-elevation myocardial infarction was the main presentation in groups I and V. Reperfusion therapies were less likely given to group V. Beta blockers were more frequently prescribed to group III in comparison to groups with higher HR. Groups I and V were associated with worse hospital outcomes. Multivariate analysis showed initial tachycardia as an independent predictor for heart failure (OR 2.2; 95%CI: 1.39-3.32), while bradycardia was independently associated with higher one-month mortality (OR 2.0; 95%CI: 1.04-3.85) CONCLUSION: The majority of ACS patients present with tachycardia. However, low or high HR is a marker of high risk that needs more attention and management.

Full Text Available Oncogenic mutations of PIK3CA, RAS (KRAS, NRAS, and BRAF have been identified in various malignancies, and activate the PI3K/AKT/mTOR and RAS/RAF/MEK pathways, respectively. Both pathways are critical drivers of tumorigenesis.Tumor tissues from 504 patients with diverse cancers referred to the Clinical Center for Targeted Therapy at MD Anderson Cancer Center starting in October 2008 were analyzed for PIK3CA, RAS (KRAS, NRAS, and BRAF mutations using polymerase chain reaction-based DNA sequencing.PIK3CA mutations were found in 54 (11% of 504 patients tested; KRAS in 69 (19% of 367; NRAS in 19 (8% of 225; and BRAF in 31 (9% of 361 patients. PIK3CA mutations were most frequent in squamous cervical (5/14, 36%, uterine (7/28, 25%, breast (6/29, 21%, and colorectal cancers (18/105, 17%; KRAS in pancreatic (5/9, 56%, colorectal (49/97, 51%, and uterine cancers (3/20, 15%; NRAS in melanoma (12/40, 30%, and uterine cancer (2/11, 18%; BRAF in melanoma (23/52, 44%, and colorectal cancer (5/88, 6%. Regardless of histology, KRAS mutations were found in 38% of patients with PIK3CA mutations compared to 16% of patients with wild-type (wtPIK3CA (p = 0.001. In total, RAS (KRAS, NRAS or BRAF mutations were found in 47% of patients with PIK3CA mutations vs. 24% of patients wtPIK3CA (p = 0.001. PIK3CA mutations were found in 28% of patients with KRAS mutations compared to 10% with wtKRAS (p = 0.001 and in 20% of patients with RAS (KRAS, NRAS or BRAF mutations compared to 8% with wtRAS (KRAS, NRAS or wtBRAF (p = 0.001.PIK3CA, RAS (KRAS, NRAS, and BRAF mutations are frequent in diverse tumors.

Full Text Available Jorge Dreyse,1 Orlando Díaz,1 Paula Repetto,2 Arturo Morales,1 Fernando Saldías,1 Carmen Lisboa11Department of Pulmonary Diseases, School of Medicine, 2School of Psychology, Pontificia Universidad Católica de Chile, Santiago, ChileBackground: In addition to smoking, acute exacerbations are considered to be a contributing factor to progression of chronic obstructive pulmonary disease (COPD. However, these findings come from studies including active smokers, while results in ex-smokers are scarce and contradictory. The purpose of this study was to evaluate if frequent acute moderate exacerbations are associated with an accelerated decline in forced expiratory volume in one second (FEV1 and impairment of functional and clinical outcomes in ex-smoking COPD patients.Methods: A cohort of 100 ex-smoking patients recruited for a 2-year follow-up study was evaluated at inclusion and at 6-monthly scheduled visits while in a stable condition. Evaluation included anthropometry, spirometry, inspiratory capacity, peripheral capillary oxygen saturation, severity of dyspnea, a 6-minute walking test, BODE (Body mass index, airflow Obstruction, Dyspnea, Exercise performance index, and quality of life (St George’s Respiratory Questionnaire and Chronic Respiratory Disease Questionnaire. Severity of exacerbation was graded as moderate or severe according to health care utilization. Patients were classified as infrequent exacerbators if they had no or one acute exacerbation/year and frequent exacerbators if they had two or more acute exacerbations/year. Random effects modeling, within hierarchical linear modeling, was used for analysis.Results: During follow-up, 419 (96% moderate acute exacerbations were registered. At baseline, frequent exacerbators had more severe disease than infrequent exacerbators according to their FEV1 and BODE index, and also showed greater impairment in inspiratory capacity, forced vital capacity, peripheral capillary oxygen saturation

The aim of this study is to develop and validate a brief instrument for the measurement of overall psychosocial impact of frequent heartburn (heartburn experienced 2+ times weekly) in the general U.S. population, yielding a single, composite score. Item reduction and psychometric analyses of an existing Frequent Heartburn (FHB) Survey, a 52-item, 13-domain, patient-reported outcomes (PRO) survey assessing the impact of frequent heartburn on psychosocial quality of life. Item reduction resulted in 9 items from the original FHB Survey measuring all domains. All retained items in this full Frequent Heartburn Index (FHBI-Full) had moderate to strong factor loadings on the underlying factor (range: 0.66-0.85) and acceptable overall model fit (CFI = 0.93, SRMR = 0.04). Coefficient alpha was 0.92. A shorter FHBI (FHBI-Brief) was created that excludes the two employment-related items. The FHBI-Brief had a coefficient alpha of 0.90. Both FHBI versions have good psychometric properties and capture a full range of psychosocial effects of frequent heartburn. Normed national scores for the FHBI are available against which an individual can compare their own FHBI score. The FHBI-Full and FHBI-Brief show promise as PRO instruments that may help individuals and clinicians better understand the effect of frequent heartburn on psychosocial functioning.

The benefits of occlusion treatment for amblyopia are well established.True compliance can be difficult to assess and is usually based on patient history. We hypothesize that more visits to the physician provides more chances to improve compliance. We conducted a prospective, comparative, blind trial in which 30 children with amblyopia were randomly assigned to be followed up more frequently (every 4 to 6 weeks) (study group) or as established on our standard regular basis (month intervals based on age in years) (control group). The primary outcome was to study differences in treatment compliance between these groups. The secondary outcome was to report compliance in a group of Chilean children and to compare survey results with adherence, to assess concordance between them. Baseline clinical characteristics were similar in the two groups. 30 patients were recruited. Mean compliance for all patients was 82%. Study group compliance was 83% versus 76% in control group (p = 0.5). Without epidemiology, intention to treat analysis (ITT), study group compliance was 97% compared to 76% in control group (p = 0.049). Pearson correlation between negative responses to a parental survey after treatment, of the percentage of adherence and compliance, was -0.57 and statistically significant (p = 0.013). There were no differences in patient compliance comparing more frequent evaluation versus a follow up evaluation based in an age according scheme. There is a high compliance to occlusion therapy in this group of Chilean children. If parents reported more negative adherence aspects in the survey, the worse the compliance.

Delayed arrival to a primary percutaneous coronary intervention (PPCI)-capable hospital following ST-elevation myocardial infarction (STEMI) is associated with poorer outcome. The influence of patient characteristics on delayed presentation during STEMI is unknown. This was a retrospective observational study. Patients presenting for PPCI from March 2008 to November 2011 in the north of England (Northumbria, Tyne and Wear) were included. The outcomes were self-presentation to a non-PPCI-capable hospital, symptom to first medical contact (STFMC) time, total ischaemic time and mortality during follow-up. STEMI patients included numbered 2297; 619 (26.9%) patients self-presented to a non-PPCI-capable hospital. STFMC of >30 min and total ischaemic time of >180 min was present in 1521 (70.7%) and 999 (44.9%) cases, respectively. Self-presentation was the strongest predictor of prolonged total ischaemic time (odds ratio, OR (95% confidence interval, CI): 5.05 (3.99-6.39)). Married patients (OR 1.38 (1.10-1.74)) and patients living closest to an Emergency Room self-presented more commonly (driving time (vs. ≤10 min) 11-20 min OR 0.66 (0.52-0.83), >20 minutes OR 0.46 (0.33-0.64). Unmarried females waited longest to call for help (OR vs. married males 1.89 (1.29-2.78) and experienced longer total ischaemic times (OR 1.51 (1.10-2.07)). Married patients had a borderline association with lower mortality (hazard ratio 0.75 (0.53-1.05), p=0.09). Unmarried female patients had the longest treatment delays. Married patients and those living closer to an Emergency Room self-present more frequently. Early and exclusive use of the ambulance service may reduce treatment delay and improve STEMI outcome. © The European Society of Cardiology 2014.

Patients on chronic warfarin therapy require regular laboratory monitoring to safely manage warfarin. Recent studies have challenged the need for routine monthly blood draws in the most stable warfarin-treated patients, suggesting the safety of less frequent laboratory testing (up to every 12 weeks). De-implementation efforts aim to reduce the use of low-value clinical practices. To explore barriers and facilitators of a de-implementation effort to reduce the use of frequent laboratory tests for patients with stable warfarin management in nurse/pharmacist-run anticoagulation clinics, we performed a mixed-methods study conducted within a state-wide collaborative quality improvement collaborative. Using a mixed-methods approach, we conducted post-implementation semi-structured interviews with a total of eight anticoagulation nurse or pharmacist staff members at five participating clinic sites to assess barriers and facilitators to de-implementing frequent international normalized ratio (INR) laboratory testing among patients with stable warfarin control. Interview guides were based on the Tailored Implementation for Chronic Disease (TICD) framework. Informed by interview themes, a survey was developed and administered to all anticoagulation clinical staff (n = 62) about their self-reported utilization of less frequent INR testing and specific barriers to de-implementing the standard (more frequent) INR testing practice. From the interviews, four themes emerged congruent with TICD domains: (1) staff overestimating their actual use of less frequent INR testing (individual health professional factors), (2) barriers to appropriate patient engagement (incentives and resources), (3) broad support for an electronic medical record flag to identify potentially eligible patients (incentives and resources), and (4) the importance of personalized nurse/pharmacist feedback (individual health professional factors). In the survey (65% response rate), staff report offering less

Full Text Available ABSTRACT Objective: to identify the mean direct cost (MDC of the most frequent procedures performed by nursing professionals on severely burned patients in an Intensive Care Unit. Method: exploratory-descriptive quantitative single-case study. The MDC was calculated by multiplying time (timed spent by nursing professionals in the performance of the procedures by the unit cost of direct labor, and adding the costs of material and medicine/solutions. Results: a MDC of US$ 0.65 (SD=0.36 was obtained for "vital signs monitoring"; US$ 10.00 (SD=24.23 for "intravenous drug administration"; US$ 5.90 (SD=2.75 for "measurement of diuresis"; US$ 0.93 (SD=0.42 for "capillary blood glucose monitoring"; and US$ 99.75 (SD=129.55 for "bandaging". Conclusion: the knowledge developed can support managerial decision-making, contribute to the efficiency distribution of the resources involved and, when possible, provide cost-containment or cost-minimization strategies without impairing the quality of nursing care.

Hypercalcemia is a frequent finding in cancer patients and can be observed in any type of cancer. The physician in charge of cancer patients often ignores non-malignant causes of hypercalcemia. Our objective was to review the causes of hypercalcemia in a large series of cancer patients. We have retrospectively studied in a Cancer Centre all consecutive hypercalcemic (Ca> 10.5 mg/dl) patients over an 8-year period. Of 699 evaluated patients, 642 were analyzed after exclusion of patients whose hypercalcemia resolved after rehydration or who had a normal Ca level after correction for protein concentrations. Clinical information was gathered on the type of cancer, its histology, whether the disease was active or in complete remission, and on the presence of bone metastases. Biochemical data included serum Ca, P(i), proteins in all patients, PTH in most patients, and PTHrP, 25OH-Vitamin D, 1,25(OH)(2)-Vitamin D, TSH, and T4 in selected cases. By order of decreasing frequency, the main causes of hypercalcemia were cancer (69.0 %), primary hyperparathyroidism (24.6 %), hyperthyroidism (2.2 %), milk alkali syndrome (0.9 %), and sarcoidosis (0.45 %). In cancer-related causes, bone metastases accounted for 53.0 % of the cases, humoral hypercalcemia of malignancy (HHM) for 35.3 % while there were 11.7 % of cases apparently due to both HHM and bone metastases. Hypercalcemia was not due to cancer in 97 % (84/87) of the patients who were in complete remission. Even in patients with active neoplastic disease, the number of patients whose hypercalcemia was not due to cancer remained clinically relevant (115/555 = 20.5 %). In the 158 patients with primary hyperparathyroidism, 92 patients were in complete remission and 66 patients had active neoplastic disease. In this large series of hypercalcemia in cancer patients, the cause was not due to cancer in almost one third of the cases. Most patients considered to be in complete remission had hypercalcemia due to a benign

Full Text Available BACKGROUND Hyperprolactinaemia is one of the common endocrine disorders seen in clinical practice. It may result due to various causes and elucidating the exact cause is necessary to formulate the right therapy. OBJECTIVE To study the various aetiologies and clinical presentation of patients presenting with hyperprolactinaemia to a tertiary care hospital. DESIGN Cross-sectional study. MATERIAL AND METHODS We collected and analysed the clinical data including hormonal status of 74 consecutive patients who presented to our department from June 2015 to May 2016 for evaluation of hyperprolactinaemia. RESULTS Majority of the subjects studied belonged to 20-29 years group (47.29% followed by 30-39 years age group (24.32%. The most common cause in our population was due to drug-induced causes (35.13%. The next common causes included idiopathic group (20.4% followed by pituitary adenomas (16.21%. There was significant female predominance (83.78% among total cases. Among women who presented with hyperprolactinaemia, menstrual irregularity (69.35% followed by galactorrhoea (35.48% were the most common presentations. CONCLUSIONS Hyperprolactinaemia is frequently seen among women who presented with either menstrual irregularity or galactorrhoea or both. Drug-induced hyperprolactinaemia is the most common cause seen in our study population.

To investigate the demographics, diagnoses and outcomes for new adult cancer patients with an initial presentation via the A&E or acute oncology teams. Patients with initial emergency presentation of malignancy have been documented to have poorer treatment outcomes and shorter survival. Patient level data on this subject is relatively limited with regard to the demographics, diagnoses and the clinical factors that may underlie late presentations. A 15 month audit of the patients presenting with a new diagnosis of malignancy was performed in 2011-2012. Data on demographics, diagnosis and outcome were assembled and analysed. The clinical data on emergency presentations were compared to reference information on the incidence and median age at presentation for each malignancy within the standard population. During the study a total of 178 new cancer patients presented via the A and E service. The most frequent diagnoses were lung cancer with 21% of cases and CNS and colorectal cancer each with 9% of cases. There was a higher incidence of emergency new presentations of lung cancer, CNS tumours, ovarian, pancreatic and testicular cancer than in the standard population, whilst breast cancer, bladder cancer and prostate cancer patients were under-represented. The median age at diagnosis was 74 and for a number of malignancies including CNS tumours, breast cancer, colorectal cancer and head and neck cancer the emergency cases presented at significantly greater ages than in the standard population. Overall 27% of patients were unfit or unsuitable for a diagnostic biopsy, this group had only a 3 month median survival compared to 14 months for those suitable for biopsy and treatment. Despite a wide range of initiatives, the emergency and late diagnosis of patients with metastatic cancer remains a significant challenge with many patients too advanced and unwell at presentation for active treatment. These patients tend to be older and have malignancies that present with either

There is growing interest in clinical research regarding the visual perspective adopted during memory retrieval, because it reflects individuals' self-attitude towards their memories of past personal events. Several autobiographical memory deficits, including low specificity of personal memories, have been identified in schizophrenia, but visual perspective during autobiographical memory retrieval has not yet been investigated in patients. The aim of this study was therefore to investigate the visual perspective with which patients visualize themselves when recalling autobiographical memories and to assess the specificity of their memories which is a major determinant of visual perspective. Thirty patients with schizophrenia and 30 matched controls recalled personal events from 4 life periods. After each recall, they were asked to report their visual perspective (Field or Observer) associated with the event. The specificity of their memories was assessed by independent raters. Our results showed that patients reported significantly fewer Field perspectives than comparison participants. Patients' memories, whether recalled with Field or Observer perspectives, were less specific and less detailed. Our results indicate that patients with schizophrenia adopt Field perspectives less frequently than comparison participants, and that this may contribute to a weakened sense of the individual of being an actor of his past events, and hence to a reduced sense of self. They suggest that this may be related to low specificity of memories and that all the important aspects involved in re-experiencing autobiographical events are impaired in patients with schizophrenia. © 2013 Elsevier B.V.

Frequent admitters to hospitals are high-cost patients who strain finite healthcare resources. However, the exact risk factors for frequent admissions, which can be used to guide risk stratification and design effective interventions locally, remain unknown. Our study aimed to identify the clinical and sociodemographic risk factors associated with frequent hospital admissions in Singapore. An observational study was conducted using retrospective 2014 data from the administrative database at Singapore General Hospital, Singapore. Variables were identified a priori and included patient demographics, comorbidities, prior healthcare utilisation, and clinical and laboratory variables during the index admission. Multivariate logistic regression analysis was used to identify independent risk factors for frequent admissions. A total of 16,306 unique patients were analysed and 1,640 (10.1%) patients were classified as frequent admitters. On multivariate logistic regression, 16 variables were independently associated with frequent hospital admissions, including age, cerebrovascular disease, history of malignancy, haemoglobin, serum creatinine, serum albumin, and number of specialist outpatient clinic visits, emergency department visits, admissions preceding index admission and medications dispensed at discharge. Patients staying in public rental housing had a 30% higher risk of being a frequent admitter after adjusting for demographics and clinical conditions. Our study, the first in our knowledge to examine the clinical risk factors for frequent admissions in Singapore, validated the use of public rental housing as a sensitive indicator of area-level socioeconomic status in Singapore. These risk factors can be used to identify high-risk patients in the hospital so that they can receive interventions that reduce readmission risk. Copyright: © Singapore Medical Association

Headaches represent a significant public health problem, but the knowledge of factors specifically related to incidence and persistence of headaches is still limited. The aim of this study was to evaluate whether gender, self-reported bruxism and variations in the dental occlusion contribute to onset and persistence of frequent headaches. The study population comprised 280 dental students, examined annually in a 2-year prospective study with a questionnaire and a clinical examination of the jaw function. In the analysis subjects were dichotomized into cases with frequent (once a week or more) or without frequent headaches (controls). The 2-year cumulative incidence was based on subjects without frequent headaches at baseline. Cases with 2-year persistent headaches reported such symptoms at all three examinations. Self-reported bruxism and factors in the dental occlusion at baseline were used as independent variables in logistic regression analyses. The 2-year cumulative incidence of frequent headaches was 21%. Female gender (OR = 2.6; CI = 1.3-5.4), self-reported bruxism (OR = 2.3; CI = 1.2-4.4) and mandibular instability in intercuspal position (OR = 3.2; CI = 1.4-7.5) were associated with incidence of frequent headaches. Persistent headaches during the observation period were present in 12 individuals (4%) and significantly related to mandibular instability in intercuspal position (OR = 6.1; CI = 1.6-22.6). The results indicate that female gender, self-reported bruxism and mandibular instability in intercuspal position are of importance in the development of frequent headaches. In management of these patients a multidisciplinary approach including dentists may be important and, thus, advocated.

In gastro-oesophageal reflux disease (GERD), heartburn responds well to acid suppression, but regurgitation is a common cause of incomplete treatment response. To assess the prevalence and burden of persistent, frequent regurgitation in primary care patients with GERD treated with acid suppression. We analysed observational data from 134 sites across six European countries in patients diagnosed with GERD. Within 3 months of the index visit, symptoms were assessed using the Reflux Disease Questionnaire, and their impact on sleep and work productivity with the Quality of Life in Reflux and Dyspepsia questionnaire and the Work Productivity and Activity Impairment Questionnaire, respectively. Patients provided information on concomitant over-the-counter (OTC) GERD medication use. Persistent, frequent (3-7 days/week) regurgitation was reported by 13.2% (153/1156) of GERD patients with no heartburn on acid suppression; the prevalence was very similar for patients with up to 2 days/week of ongoing mild heartburn. Among patients without heartburn, sleep disturbance of any type was reported by 50.7-60.1% with persistent, frequent regurgitation, compared with 38.1-51.1% and 14.4-19.2% of those with less frequent or no regurgitation respectively. Persistent, frequent regurgitation was associated with increased use of OTC medication and more hours of work missed, whether mild, infrequent heartburn was present or not. Frequent regurgitation, which persisted in 12-13% of patients with no or infrequent, mild heartburn on acid suppression, negatively affected sleep and work productivity, and increased use of OTC medication. Persistent, frequent regurgitation is problematic for primary care patients with GERD. © 2013 Blackwell Publishing Ltd.

The catalytic subunit of DNA polymerase epsilon (POLE1) functions primarily in nuclear DNA replication and repair. Recently, POLE1 mutations were detected frequently in colorectal and endometrial carcinomas while with lower frequency in several other types of cancer, and the p.P286R and p.V411L mutations were the potential mutation hotspots in human cancers. Nevertheless, the mutation frequency of POLE1 in ovarian cancer still remains largely unknown. Here, we screened a total of 251 Chinese samples with distinct subtypes of ovarian carcinoma for the presence of POLE1 hotspot mutations by direct sequencing. A heterozygous somatic POLE1 mutation, p.S297F (c.890C>T), but not p.P286R and p.V411L hotspot mutations observed in other cancer types, was identified in 3 out of 37 (8.1%) patients with ovarian endometrioid carcinoma; this mutation was evolutionarily highly conserved from Homo sapiens to Schizosaccharomyces. Of note, the POLE1 mutation coexisted with mutation in the ovarian cancer-associated PPP2R1A (protein phosphatase 2, regulatory subunit A, α) gene in a 46-year-old patient, who was also diagnosed with ectopic endometriosis in the benign ovary. In addition, a 45-year-old POLE1-mutated ovarian endometrioid carcinoma patient was also diagnosed with uterine leiomyoma while the remaining 52-year-old POLE1-mutated patient showed no additional distinctive clinical manifestation. In contrast to high frequency of POLE1 mutations in ovarian endometrioid carcinoma, no POLE1 mutations were identified in patients with other subtypes of ovarian carcinoma. Our results showed for the first time that the POLE1 p.S297F mutation, but not p.P286R and p.V411L hotspot mutations observed in other cancer types, was frequent in Chinese ovarian endometrioid carcinoma, but absent in other subtypes of ovarian carcinoma. These results implicated that POLE1 p.S297F mutation might be actively involved in the pathogenesis of ovarian endometrioid carcinoma, but might not be actively

Brain magnetic resonance imaging (BMRI) lesions were classically not reported in neuromyelitis optica (NMO). However, BMRI lesions are not uncommon in NMO spectrum disorder (NMOSD) patients. To report BMRI characteristic abnormalities (location and configuration) in NMOSD patients at presentation. Medical records and BMRI characteristics of 79 patients with NMOSD (during the first documented attack) in Argentina, Brazil and Venezuela were reviewed retrospectively. BMRI abnormalities were observed in 81.02% of NMOSD patients at presentation. Forty-two patients (53.1%) showed typical-NMOSD abnormalities. We found BMRI abnormalities at presentation in the brainstem/cerebellum (n = 26; 32.9%), optic chiasm (n = 16; 20.2%), area postrema (n = 13; 16.4%), thalamus/hypothalamus (n = 11; 13.9%), corpus callosum (n = 11; 13.9%), periependymal-third ventricle (n = 9; 11.3%), corticospinal tract (n = 7; 8.8%), hemispheric white matter (n = 1; 1.2%) and nonspecific areas (n = 49; 62.03%). Asymptomatic BMRI lesions were more common. The frequency of brain MRI abnormalities did not differ between patients who were positive and negative for aquaporin 4 antibodies at presentation. Typical brain MRI abnormalities are frequent in NMOSD at disease onset. Copyright © 2017 Elsevier B.V. All rights reserved.

Retinitis pigmentosa (RP) is a highly heterogeneous genetic disease. The USH2A gene, which accounts for approximately 74-90% of Usher syndrome type 2 (USH2) cases, is also one of the major autosomal recessive RP (arRP) causative genes among Caucasian populations. To identify disease-causing USH2A gene mutations in Japanese RP patients, all 73 exons were screened for mutations by direct sequencing. In total, 100 unrelated Japanese RP patients with no systemic manifestations were identified, excluding families with obvious autosomal dominant inheritance. Of these 100 patients, 82 were included in this present study after 18 RP patients with very likely pathogenic EYS (eyes shut homolog) mutations were excluded. The mutation analysis of the USH2A revealed five very likely pathogenic mutations in four patients. A patient had only one very likely pathogenic mutation and the others had two of them. Caucasian frequent mutations p.C759F in arRP and p.E767fs in USH2 were not found. All the four patients exhibited typical clinical features of RP. The observed prevalence of USH2A gene mutations was approximately 4% among Japanese arRP patients, and the profile of the USH2A gene mutations differed largely between Japanese patients and previously reported Caucasian populations.

Oropharyngeal squamous cell carcinoma (OPSCC) is divided in two different disease entities depending on HPV involvement. We investigated differences in presenting symptoms and clinical findings in patients with HPV-positive and -negative OPSCC tumors. Altogether 118 consecutive patients diagnosed with primary OPSCC between 2012 and 2014 at the Helsinki University Hospital were included. HPV-status of the tumors was assessed by PCR detection of HPV DNA and immunostaining with p16-INK4a antibody. Fifty-one (47.7%) of the patients had HPV-positive and 56 (52.3%) HPV-negative tumors. Forty-nine (49/51, 96.1%) of the HPV+ tumors were also p16+ showing high concordance. The most common presenting symptom among HPV+/p16+ patients was a neck mass (53.1%), whereas any sort of pain in the head and neck area was more frequently related to the HPV-/p16- (60.0%) group. HPV+/p16+ tumors had a tendency to locate in the tonsillar complex and more likely had already spread into regional lymph nodes compared with HPV-/p16- tumors. Smoking and heavy alcohol consumption were significantly more common among HPV-/p16- patients but also rather common among HPV+/p16+ patients. This analysis of symptoms and signs confirm that OPSCC can be dichotomized in two distinct disease entities as defined by HPV status.

End of life is an unfortunate but inevitable phase of the heart failure patients' journey. It is often preceded by a stage in the progression of heart failure defined as advanced heart failure, and characterised by poor quality of life and frequent hospitalisations. In clinical practice, the efficacy of treatments for advanced heart failure is often assessed by parameters such as clinical status, haemodynamics, neurohormonal status, and echo/MRI indices. From the patients' perspective, however, quality-of-life-related parameters, such as functional capacity, exercise performance, psychological status, and frequency of re-hospitalisations, are more significant. The effects of therapies and interventions on these parameters are, however, underrepresented in clinical trials targeted to assess advanced heart failure treatment efficacy, and data are overall scarce. This is possibly due to a non-universal definition of the quality-of-life-related endpoints, and to the difficult standardisation of the data collection. These uncertainties also lead to difficulties in handling trade-off decisions between quality of life and survival by patients, families and healthcare providers. A panel of 34 experts in the field of cardiology and intensive cardiac care from 21 countries around the world convened for reviewing the existing data on quality-of-life in patients with advanced heart failure, discussing and reaching a consensus on the validity and significance of quality-of-life assessment methods. Gaps in routine care and research, which should be addressed, were identified. Finally, published data on the effects of current i.v. vasoactive therapies such as inotropes, inodilators, and vasodilators on quality-of-life in advanced heart failure patients were analysed.

Unverricht-Lundborg disease (EPM1A) is frequently due to an unstable expansion of a dodecamer repeat in the CSTB gene, whereas other types of mutations are rare. EPM1A due to homozygous expansion has a rather stereotyped presentation with prominent action myoclonus. We describe eight patients with five different compound heterozygous CSTB point or indel mutations in order to highlight their particular phenotypical presentations and evaluate their genotype-phenotype relationships. We screened CSTB mutations by means of Southern blotting and the sequencing of the genomic DNA of each proband. CSTB messenger RNA (mRNA) aberrations were characterized by sequencing the complementary DNA (cDNA) of lymphoblastoid cells, and assessing the protein concentrations in the lymphoblasts. The patient evaluations included the use of a simplified myoclonus severity rating scale, multiple neurophysiologic tests, and electroencephalography (EEG)-polygraphic recordings. To highlight the particular clinical features and disease time-course in compound heterozygous patients, we compared some of their characteristics with those observed in a series of 40 patients carrying the common homozygous expansion mutation observed at the C. Besta Foundation, Milan, Italy. The eight compound heterozygous patients belong to six EPM1A families (out of 52; 11.5%) diagnosed at the Laboratory of Genetics of the Galliera Hospitals in Genoa, Italy. They segregated five different heterozygous point or indel mutations in association with the common dodecamer expansion. Four patients from three families had previously reported CSTB mutations (c.67-1G>C and c.168+1_18del); one had a novel nonsense mutation at the first exon (c.133C>T) leading to a premature stop codon predicting a short peptide; the other three patients from two families had a complex novel indel mutation involving the donor splice site of intron 2 (c.168+2_169+21delinsAA) and leading to an aberrant transcript with a partially retained intron

For children with asthma, emergency department (ED) visits are common, expensive, and often avoidable. Though several factors are associated with ED use (demographics, comorbidities, insurance, medications), its predictability using electronic health record (EHR) data is understudied. We used a retrospective cohort study design and EHR data from one center to examine the relationship of patient factors in 1 year (2013) and the likelihood of frequent ED use (≥2 visits) in the following year (2014), using bivariate and multivariable statistics. We applied and compared several machine-learning algorithms to predict frequent ED use, then selected a model based on accuracy, parsimony, and interpretability. We identified 2691 children. In bivariate analyses, future frequent ED use was associated with demographics, co-morbidities, insurance status, medication history, and use of healthcare resources. Machine learning algorithms had very good AUC (area under the curve) values [0.66-0.87], though fair PPV (positive predictive value) [48-70%] and poor sensitivity [16-27%]. Our final multivariable logistic regression model contained two variables: insurance status and prior ED use. For publicly insured patients, the odds of frequent ED use were 3.1 [2.2-4.5] times that of privately insured patients. Publicly insured patients with 4+ ED visits and privately insured patients with 6+ ED visits in a year had ≥50% probability of frequent ED use the following year. The model had an AUC of 0.86, PPV of 56%, and sensitivity of 23%.

Summary Background Telehealth data overload through high alert generation is a significant barrier to sustained adoption of telehealth for managing HF patients. Objective To explore the factors contributing to frequent telehealth alerts including false alerts for Medicare heart failure (HF) patients admitted to a home health agency. Materials and Methods A mixed methods design that combined quantitative correlation analysis of patient characteristic data with number of telehealth alerts and qualitative analysis of telehealth and visiting nurses’ notes on follow-up actions to patients’ telehealth alerts was employed. All the quantitative and qualitative data was collected through retrospective review of electronic records of the home heath agency. Results Subjects in the study had a mean age of 83 (SD = 7.6); 56% were female. Patient co-morbidities (ppatient characteristics along with establishing patient-centered telehealth outcome goals may allow meaningful generation of telehealth alerts. Reducing avoidable telehealth alerts could vastly improve the efficiency and sustainability of telehealth programs for HF management. PMID:24454576

Many patients with common cancers are late diagnosed. Identify consultation profiles and clinical features in patients with the seven most common cancers, who had consulted a general practitioner (GP) frequently before their cancer diagnosis. A case-control study was conducted in Region Västra Götaland, Sweden. A total of 2570 patients, diagnosed in 2011 with prostate, breast, colorectal, lung, gynaecological and skin cancers including malignant melanoma, and 9424 controls were selected from the Swedish Cancer Register and a regional health care database. Diagnostic codes [International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10)] from primary care for patients with ≥4 GP consultations registered in the year before cancer diagnosis were collected. Likelihood ratios (LRs) were calculated for variables associated with the different cancers. Fifty-six percent of the patients had consulted a GP four or more times in the year before cancer diagnosis. Alarm symptoms or signs represented 60% of the codes with the highest LR, but only 40% of the 10 most prevalent codes. Breast lump had the highest LR, 11.9 [95% confidence interval (CI) 8.0-17.8]; abnormalities of plasma proteins had an LR of 5.0 (95% CI 3.0-8.2) and abnormal serum enzyme levels had an LR of 4.6 (95% CI 3.6-5.9). Early clinical features associated with cancer had been registered already at the first two GP consultations. One out of six clinical features associated with cancer were presented by cancer patients with four or more pre-referral consultations already at the two first consultations. These early clinical features that were focal and had benign characteristics might have been missed diagnostic opportunities.

Frequently Used Coping Scales: A Meta-Analysis.

Kato, Tsukasa

2015-10-01

This article reports the frequency of the use of coping scales in academic journals published from 1998 to 2010. Two thousand empirical journal articles were selected from the EBSCO database. The COPE, Ways of Coping Questionnaire, Coping Strategies Questionnaire, Coping Inventory for Stressful Situations, Religious-COPE and Coping Response Inventory were frequently mentioned. In particular, the COPE (20.2%) and Ways of Coping Questionnaire (13.6%) were used the most frequently. In this literature reviewed, coping scales were most often used to assess coping with health issues (e.g. illness, pain and medical diagnoses) over other types of stressors, and patients were the most frequent participants. Further, alpha coefficients were estimated for the COPE subscales, and correlations between the COPE subscales and coping outcomes were calculated, including depressive symptoms, anxiety, negative affect, psychological distress, physical symptoms and well-being.

To determine the presentation and management outcome of thoracic trauma in a tertiary care setting. A total of 143 patients, who presented with chest trauma, were included in the study. All the patients were assessed by the history, physical examination and ancillary investigations. Appropriate managements were instituted as required. Data was described in percentages. out of 143 patients, 119 (83)% were males and 24 (17)% were females. Most of the patients belonged to the age group of 21-50 years. Ninety seven (66)% patients were admitted for indoor management. Blunt injury was found in 125 (87.4%) patients, while penetrating injuries in only 18 (12.6%) patients. Road Traffic Accidents (RTAs) were the commonest cause of trauma (n=103, 72%). Rib fracture was the commonest chest injury (74% patients). Head injury was the most frequently associated injury (18% of the patients). Tube thoracostomy was the commonest intervention undertaken in 65 (45%) patients. Seventeen (11.88%) patients were managed with mechanical ventilation. there were 17 deaths with a mortality rate of 11.88%. Thoracic trauma is an important cause of hospitalization, morbidity and mortality in the younger population. RTAs constitute the leading cause of thoracic trauma in our setup. Tube thoracostomy is the most frequent and at times the only invasive procedure required as a definitive measure in thoracic trauma patients. A policy of selective hospitalization helps to avoid unnecessary hospital admissions. (author)

2005-01-01

OBJECTIVE: Patients use and store considerable amounts of drugs. The aim of the present study was to identify potential drug-drug interactions between drugs used by patients recently discharged from the hospital and, subsequently, to estimate the clinical implications of these interactions. METHODS......: Patients were visited within 1 week following their discharge from hospital and interviewed about their drug use. Stored products were inspected. We used a bibliography (Hansten and Horn; Wolters Kluwer Health, St. Louis, Mo., 2004) to identify and classify potential drug-drug interactions. RESULTS......: eight per patient; range: 1-24). With respect to those drugs used daily or on demand, 476 potential interactions were identified (126 patients); none were class 1 (always avoid drug combination) and 25 were class 2 (usually avoid combination; 24 patients). Eleven of the potential class 2 interactions...

Full Text Available In males, precocious puberty (PP is defined as the development of secondary sexual characteristics before age 9 years. PP is usually idiopathic; though, organic abnormalities including tumors are more frequently found in male patients with PP. However, advanced puberty in male also can be an important clinical manifestation in tumors. We report 2 cases of rapidly progressive puberty in males, each associated with a germ-cell tumor. First, an 11-year-old boy presented with mild fever and weight loss for 1 month. Physical examination revealed a pubertal stage of G3P3 with 10-mL testes. Investigations revealed advanced bone age (16 years with elevated basal luteinizing hormone and testosterone levels. An anterior mediastinal tumor was identified by chest radiography and computed tomography, and elevated α-fetoprotein (AFP and β-human chorionic gonadotropin (β-hCG levels were noted. Histopathologic analysis confirmed a yolk-sac tumor. Second, a 12-year-old boy presented with diplopia, polydipsia, and polyuria for 4 months. Physical examination revealed a pubertal stage of G3P3 with 8-mL testes. Bone age was advanced (16 years and laboratory tests indicated panhypopituitarism with elevated testosterone level. A mixed germ-cell tumor was diagnosed with elevated AFP and β-hCG levels. Of course, these patients also have other symptoms of suspecting tumors, however, rapidly progressive puberty can be the more earlier screening sign of tumors. Therefore, in male patients with accelerated or advanced puberty, malignancy should be considered, with evaluation of tumor markers. In addition, advanced puberty in male should be recognized more widely as a unique sign of neoplasm.

To describe the clinical phenotype of idiopathic rapid eye movement (REM) sleep behavior disorder (IRBD) at presentation in a sleep center. Clinical history review of 203 consecutive patients with IRBD identified between 1990 and 2014. IRBD was diagnosed by clinical history plus video-polysomnographic demonstration of REM sleep with increased electromyographic activity linked to abnormal behaviors. Patients were 80% men with median age at IRBD diagnosis of 68 y (range, 50-85 y). In addition to the already known clinical picture of IRBD, other important features were apparent: 44% of the patients were not aware of their dream-enactment behaviors and 70% reported good sleep quality. In most of these cases bed partners were essential to convince patients to seek medical help. In 11% IRBD was elicited only after specific questioning when patients consulted for other reasons. Seven percent did not recall unpleasant dreams. Leaving the bed occurred occasionally in 24% of subjects in whom dementia with Lewy bodies often developed eventually. For the correct diagnosis of IRBD, video-polysomnography had to be repeated in 16% because of insufficient REM sleep or electromyographic artifacts from coexistent apneas. Some subjects with comorbid obstructive sleep apnea reported partial improvement of RBD symptoms following continuous positive airway pressure therapy. Lack of therapy with clonazepam resulted in an increased risk of sleep related injuries. Synucleinopathy was frequently diagnosed, even in patients with mild severity or uncommon IRBD presentations (e.g., patients who reported sleeping well, onset triggered by a life event, nocturnal ambulation) indicating that the development of a neurodegenerative disease is independent of the clinical presentation of IRBD. We report the largest IRBD cohort observed in a single center to date and highlight frequent features that were not reported or not sufficiently emphasized in previous publications. Physicians should be aware of

People with cancer attend emergency departments (EDs) for many reasons. Improved understanding of the specific needs of these patients may assist in optimizing health service delivery. ED presentation and hospital utilization characteristics were explored for people with cancer and compared with those patients without cancer. This descriptive, retrospective, multicentre cohort study used hospital administrative data. Descriptive and inferential statistics were used to summarise and compare ED presentation characteristics amongst cancer and non-cancer groups. Predictive analyses were used to identify ED presentation features predictive of hospital admission for cancer patients. Outcomes of interest were level of acuity, ED and inpatient length of stay, re-presentation rates and admission rates amongst cancer patients and non-cancer patients. ED (529,377) presentations occurred over the 36 months, of which 2.4% (n = 12,489) were cancer-related. Compared with all other attendances, cancer-related attendances had a higher level of acuity, requiring longer management time and length of stay in ED. Re-presentation rates for people with cancer were nearly double those of others (64 vs 33%, p < 0.001), with twice the rate of hospital admission (90 vs 46%, p < 0.001), longer inpatient length of stay (5.6 vs 2.8 days, p < 0.001) and had higher inpatient mortality (7.9 vs 1.0%, p < 0.001). Acuity and arriving by ambulance were significant predictors of hospital admission, with cancer-related attendances having ten times the odds of admission compared to other attendances (OR = 10.4, 95% CI 9.8-11.1). ED presentations by people with cancer represent a more urgent, complex caseload frequently requiring hospital admission when compared to other presentations, suggesting that for optimal cancer care, close collaboration and integration of oncology, palliative care and emergency medicine providers are needed to improve pathways of care.

Propionic acidemia is a rare autosomal recessive inherited metabolic disorder that can inhibit the synthesis of N-acetylglutamate, the obligatory activator in urea synthesis, leading to hyperammonemia. N-carbamylglutamate ameliorates hyperammonemia in decompensated propionic acidemia. The effects of long-term continuous N-acetylglutamate administration in such patients are unknown. We report our clinical experience with continuous administration of N-acetylglutamate for 6 years in a patient with propionic acidemia frequently presenting with hyperammonemia. A male Caucasian patient with frequently decompensated propionic acidemia and hyperammonemia was admitted 78 times for acute attacks during the first 9 years of his life. Continuous daily treatment with oral N-carbamylglutamate 100 mg/kg (50 mg/kg after 6 months) was initiated. During 6 years of treatment, he had a significant decrease in his mean plasma ammonia levels (75.7 μmol/L vs. 140.3 μmol/L before N-carbamylglutamate therapy, p N-acetylglutamate administration outside the emergency setting. If this observation is confirmed, future studies should aim to optimize the dosage and explore effects of the dosage requirements on other drugs and on protein tolerance.

Isolated hypogonadotropic hypogonadism (IHH) is a rare disorder with pubertal delay, normal (normoosmic-IHH, nIHH) or defective sense of smell (Kallmann syndrome, KS). Other reproductive and non-reproductive anomalies might be present although information on their frequency are scanty, particularly according to the age of presentation. Observational cohort study carried out between January 2008 and June 2016 within a national network of academic or general hospitals. We performed a detailed phenotyping of 503 IHH patients with: (1) manifestations of hypogonadism with low sex steroid hormone and low/normal gonadotropins; (2) absence of expansive hypothalamic/pituitary lesions or multiple pituitary hormone defects. Cohort was divided on IHH onset (PPO, pre-pubertal onset or AO, adult onset) and olfactory function: PPO-nIHH ( n  = 275), KS ( n  = 184), AO-nIHH ( n  = 36) and AO-doIHH (AO-IHH with defective olfaction, n  = 8). 90% of patients were classified as PPO and 10% as AO. Typical midline and olfactory defects, bimanual synkinesis and familiarity for pubertal delay were also found among the AO-IHH. Mean age at diagnosis was significantly earlier and more frequently associated with congenital hypogonadism stigmata in patients with Kallmann's syndrome (KS). Synkinesis, renal and male genital tract anomalies were enriched in KS. Overweight/obesity are significantly associated with AO-IHH rather than PPO-IHH. Patients with KS are more prone to develop a severe and complex phenotype than nIHH. The presence of typical extra-gonadal defects and familiarity for PPO-IHH among the AO-IHH patients indicates a common predisposition with variable clinical expression. Overall, these findings improve the understanding of IHH and may have a positive impact on the management of patients and their families. © 2018 European Society of Endocrinology.

However, many COPD patients are not diagnosed because of underrecognition or underdiagnosis of this disease among many patients and physicians. One possible reason is underrecognition of spirometry. In this study, we examined the prevalence of airflow limitation and underlying disease in patients with airflow limitation.Methodology: From April 2006 to March 2008, patients who had spirometry performed were examined. The original disease of patients, pulmonary function tests, smoking status, and respiratory symptoms were surveyed from their medical records.Results: Of all patients who had spirometry performed, 15.8% showed airflow limitation (FEV1/FVC < 0.7. A variety of diseases were observed in patients with airflow limitation. Among all diseases, cardiovascular disease was the highest and gastrointestinal malignant disease had the second highest prevalence in patients with airflow limitation.Conclusion: COPD might be frequent in conditions of comorbidity in patients treated for various diseases. Attention should be paid to the possibility of co-existence of COPD and the influence of COPD on these patients.Keywords: airflow limitation, chronic obstructive pulmonary disease, comorbidity, spirometry, prevalence

Purpose: The purpose of this study was to assess the clinical value of HRCT of the lung in patients with known HIV-infection and acute lung disease. In a prospective study a HRCT was performed in 31 patients infected with the HIV-1 virus, mainly stage C (CDC), who had acute pulmonary symptoms. Precondition for the HRCT examination was a normal or non-specific chest radiograph. A provoked sputum as well as bronchoscopy with bronchoalveolar lavage and/or transbronchial biopsy were performed concurrently. In 24 out of 31 cases a pathogenic organism was identified. 19 of these 24 patients showed abnormal HRCT findings. The most frequent pathogenic organism was Pneumocystis carinii (n=12). 9 out of these 12 patients (75%) showed pathological HRCT findings consisting of ground-glass opacity. Specific patterns of attenuation could not be worked out except for Pneumocystis carinii infection. Compared to bronchoalveolar lavage, the diagnostic value of HRCT is inferior; it is however helpful in the early stage of disease, when the pathogenic organism has not yet been identified, HRCT may demonstrate parenchymal abnormalities in patients with normal radiographic findings. Compared to bronchoalveolar lavage and induced sputum, HRCT can provide conclusive results within a short time. (orig.) [de

Introduction: systemic sclerosis is an autoimmune disease characterized by endothelial damage, and skin, vessel and internal organ fibrosis and inflammation. There are differences in terms of frequency, severity and prognosis for the different ethnic groups, what reinforces the importance of the study in each geographical region with the purpose of enabling early diagnosis of its incipient symptoms.Methods: we conducted a descriptive and retrospective study form March 2006 through March 2008, including patients with a final diagnosis of systemic sclerosis, who are treated at the Systemic Autoimmune Diseases Unit at the Clinicas Hospital. Results: 31 women were included in the study, average follow-up of patients was 39.2 months, and average age at the time of diagnosis was 47.6 years. Eleven patients (35,5) presented diffuse disease and 20 (64.5) of them evidenced limited disease. Thirty patients presented Raynaud's phenomenon. In 92 of cases capilaroscopy showed a sclerodermiform pattern. In terms of the respiratory system, we found interstitial pathology in 25 of cases, pulmonary arterial hypertension in 22.2 and are restrictive pattern in respiratory function studies in 35.5. Also, 67.7 presented digestive manifestations and 9.6 developed sclerodermic renal crisis. We found anti-nuclear antibodies (ANA) in 29 out of 31 patients (93,5) patients; 16 presented anticentromere antibodies and five anti-topoisomerasa-I antibodies. The four patients (12.9)who died during follow-up presented common elements such as diffuse sclerosis, digital ulcers and severe respiratory compromise. Conclusions: the clinical and immune characteristics found in our study were similar to those described in other series. Should there be no specific treatment, it is essential to perform regular assessment of visceral impact in order to control and delay complications which result in high morbimortality rates.

2016-04-01

A retrospective review of the demographics, co-morbidities and substance misuse of the 20 most frequent presenters to the Mater Misericordiae University Hospital emergency department during 2014 was carried out in an attempt to better understand the epidemiology of their presentations. Eighty-five percent were male and 15% female (p<0.001). The average age was 40.6 years with a median 38.5 years. All were unemployed and 7 (35%) had no fixed abode. Thirteen patients (65%) lived an average of 4.5 kilometres from the ED. In this study the presence of a mental illness, homelessness, alcohol or drug misuse were associated with significantly higher attendance rates (p=0.001, p<0.001, p<0.05, p<0.001 respectively). Early identification of these patients and targeting them for effective case-based community-led treatment strategies could improve their quality of life, decrease their cost of care and ultimately lead to more effective utilisation of our already overburdened emergency departments.

Full Text Available Development of autoantibodies against coagulation factors is an uncommon bleeding disorder associated with cancer, autoimmune conditions, pregnancy, or no apparent disease. Spontaneous FVIII inhibitors are the most frequently encountered; those against FXI have been only anecdotally reported. We report a case of acquired FXI inhibitor presenting as fatal intracranial spontaneous bleeding in an elderly patient with history of cancer and previous transfusions. Few cases of acquired FXI inhibitor have been reported in association with connective tissue disease, cancer, or surgery. Bleeding includes mucocutaneous bleeding, postsurgical hemorrhage, or life-threatening events. Treatment consists of arresting the bleeding and inhibitor eradication. High degree of suspicion is essential to promptly diagnose and treat this uncommon condition.

Objective of this study was to describe the patient characteristics and clinical presentation of laboratory confirmed lymphogranuloma venereum (LGV) cases, diagnosed at the Institute of Tropical Medicine (ITM), Antwerp, Belgium. Demographic and biomedical characteristics of all patients with chlamydia-positive sample results were retrieved for the years 2013 and 2014. Samples were obtained from both symptomatic and asymptomatic patients who consulted at the HIV/STI clinic. Fifty four patients with laboratory confirmed LGV were detected among 3885 nucleic acid amplification tests (NAATs) performed for the detection of chlamydia during the two years under review. Fifty three were men and equally fifty three had sex with men only (MSM). HIV (87%) and HCV (31.5%) were common concomitant infections, whilst anal gonorrhoea and syphilis were detected at the moment of the LGV diagnosis among 19 (35.2%) and 6 (11.0%) cases respectively. All cases were symptomatic, except one. The most frequent symptoms that were recorded could be categorised as proctitis (in 40 patients (74%)). Lymphadenopathy, anal and genital ulcers were signs that were present in 7 (13.0%), 4 (7.4%) and 2 patients (3.7%) respectively. LGV remains an important sexually transmitted disease among MSM. In this retrospective study, the far majority of LGV was detected amongst symptomatic persons. HCV, HIV, anal gonorrhoea and syphilis were associated co-infections. Proctitis in a high risk patient should alert the clinician for the possibility of an STI. © Acta Gastro-Enterologica Belgica.

This study describes the frequency and the type of anemia seen in patients with nonimmune chronic idiopathic neutropenia of adults (NI-CINA). We found that NI-CINA patients had low hemoglobin levels and increased serum concentrations of erythropoietin (EPO), tumor necrosis factor-alpha (TNF-alpha), and interleukin-1beta (IL-1beta). The hemoglobin levels correlated positively with the number of circulating neutrophils and inversely with the levels of EPO and TNF-alpha but not of IL-1beta. Anemia, defined as the reduction of the hemoglobin below 12.0 g/dl for women and 13.3 g/dl for men, was found in 23 out of 148 patients studied, a proportion of 15.5%. Two of the anemic patients had iron deficiency anemia (8.7%), 11 had anemia of chronic disease (ACD; 47.8%) presenting with normal or slightly reduced erythrocytic indices, low serum iron, and increased serum ferritin, and the remaining ten had anemia of undefined pathogenesis (AUP; 43.5%) with normal or slightly decreased erythrocytic indices, serum iron ranging from 43 to 88 microg/dl, and ferritin values ranging from 12 to 50 ng/ml. We conclude that ACD is the more frequent type of anemia seen in patients with NI-CINA, and that pro-inflammatory cytokines, notably TNF-alpha, may be involved in the pathogenesis of both ACD and AUP, given that serum levels of the cytokine were significantly increased and that the EPO response to anemia was blunted in these patients. These findings further support our previously reported suggestion for the possible existence, in NI-CINA patients, of an unrecognized low-grade chronic inflammatory process that may be involved in the pathogenesis of the disorder.

To determine the coital frequency among infertile couples and which factors are associated with less frequent coitus. Cross-sectional study. Tertiary-level male infertility clinic. A total of 1,298 infertile men. Administration of computer-based survey, semen analysis, and serum hormone evaluation. Monthly coital frequency. A total of 1,298 patients presented to clinic for infertility consultation and completed the computer-based survey. The median male age was 35 years (interquartile range [IQR] 32-39 years) and the median duration of infertility was 2 years (IQR 1-4 years) before consultation. Median monthly coital frequency was seven (IQR 5-10; range 0-40); 24% of couples were having intercourse ≤ 4 times per month. Overall, 0.6%, 2.7%, 4.8%, 5.8%, and 10.8% of the men reported having intercourse 0, 1, 2, 3, and 4 times per month, respectively. When simultaneously taking into account the influence of age, libido, erectile function, and semen volume on coital frequency, older patients had 1.05 times higher odds (per year of age) of less frequent coitus (odds ratio 1.05, 95% confidence interval 1.03-1.08). In addition, patients with better erectile function had 1.12 times higher odds (per point on Sexual Health Inventory for Men scale) of more frequent coitus (odds ratio 1.12, 95% confidence interval 1.09-1.18). Similar to the general population, most infertile couples report having coitus more than four times per month. Older male age and erectile dysfunction are independent risk factors for less frequent coitus among infertile men, which could have an impact on fertility. Coital frequency should be considered in infertility assessments. Copyright © 2013 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

We explored the relationship between erythema nodosum (EN) and sex, age, serum angiotensin converting enzyme (ACE), bronchoalveolar lavage lymphocytosis (BAL-I), interstitial granulomas and radiological stage in patients presenting with pulmonary sarcoidosis in Ireland. Sixty-nine patients diagnosed with sarcoidosis between 2003 and 2006 were studied. Forty one patients (59%) were male. Sixteen patients (23%) presented with EN. Forty one patients of 65 (63%) had transbronchial biopsies demonstrating non-caseating granulomas. Patients with sarcoidosis presenting with EN were more likely to be female (p=0.042), younger (p=0.012) and have earlier stage pulmonary disease (p=0.02). There were no correlations between serum ACE, interstitial granulomas and disease stage. BAL-I did however predict increasing disease radiological stage (p=0.042). In this study, one quarter of patients with sarcoidosis presented with EN among their presenting features. These patients were more likely to be young females with early stage radiological disease.

Characteristics of older frequent users of Emergency Departments (EDs) are poorly understood. Our aim was to examine the characteristics of the ED frequent attenders (FAs) by age (under 65 and over 65 years). We examined the prevalence of FA attending the ED of an Urban Teaching Hospital in a cross-sectional study between 2009 and 2011. FA was defined as an individual who presented to the ED four or more times over a 12-month period. Randomly selected groups of FA and non-FA from two age groups (under 65 and over 65 years) were then examined to compare the characteristics between older FAs and non-FAs and older FAs and younger FAs. Logistic regression was used to calculate the odds ratio and 95% confidence intervals for 12-month mortality in FA compared with non-FA aged at least 65 years. Overall, 137 150 ED attendances were recorded between 2009 and 2011. A total of 21.6% were aged at least 65 years, 4.4% of whom were FAs, accounting for 18.4% of attendances by patients older than 65 years. There was a bimodal age distribution of FA (mean±SD; under 65 years 40±12.7; and over 65 years 76.9±7.4). Older FAs were five times more likely to present outside normal working hours and 5.5 times more likely to require admission. Cardiovascular emergencies were the most common complaint, in contrast with the younger FA group, where injury and psychosocial conditions dominated. The odds ratio for death at 12 months was 2.07 (95% confidence interval 0.93-4.63; P=0.07), adjusting for age and sex. One-in-five ED patients older than 65 years of age are FAs. Older FAs largely present with complex medical conditions. Enhanced access to expert gerontology assessment should be considered as part of effective intervention strategies for older ED users.

Genitourinary neurofibromas with clitoral involvement in neurofibromatosis type 1 are rare, and even more infrequent are the neurofibromas involving genitalia in males. The most frequent presenting sign of neurofibroma in females is clitoromegaly with pseudopenis, and enlarged penis is the most common sign in males. Labium majus neurofibroma not associated with clitoral involvement is extremely rare. Magnetic resonance imaging demonstration of the neurofibromas has seldom been reported. We report 4 children, 3 girls and 1 boy, with plexiform neurofibromas involving the external genitalia. Three of the 4 patients had histologic confirmation of neurofibroma. Two girls with clitoral hypertrophy had a neurofibroma that infiltrated the clitoris and extended unilaterally to the lower bladder wall. One girl had a plexiform neurofibroma that affected a labium. One boy with asymmetric penile hypertrophy since 2 years of age and ipsilateral gluteal hypertrophy had plexiform neurofibromas that extended between the left lumbogluteal and penile regions, infiltrating the left rectum wall and bladder with compression of both structures, the left prostate, and the left half of the cavernous corpi with hypertrophy of this part and asymmetry of the penis. Magnetic resonance imaging demonstrated in all patients that external genitalia and plexiform neurofibroma formed images of nondetachable structures. However, hermaphroditism was discarded by chromosomal study in all 3 girls before ratifying the diagnosis of external genitalia neurofibroma.

Full Text Available Abstract Background The four-transmembrane MAL2 protein is frequently overexpressed in breast carcinoma, and MAL2 overexpression is associated with gain of the corresponding locus at chromosome 8q24.12. Independent expression microarray studies predict MAL2 overexpression in ovarian carcinoma, but these had remained unconfirmed. MAL2 binds tumor protein D52 (TPD52, which is frequently overexpressed in ovarian carcinoma, but the clinical significance of MAL2 and TPD52 overexpression was unknown. Methods Immunohistochemical analyses of MAL2 and TPD52 expression were performed using tissue microarray sections including benign, borderline and malignant epithelial ovarian tumours. Inmmunohistochemical staining intensity and distribution was assessed both visually and digitally. Results MAL2 and TPD52 were significantly overexpressed in high-grade serous carcinomas compared with serous borderline tumours. MAL2 expression was highest in serous carcinomas relative to other histological subtypes, whereas TPD52 expression was highest in clear cell carcinomas. MAL2 expression was not related to patient survival, however high-level TPD52 staining was significantly associated with improved overall survival in patients with stage III serous ovarian carcinoma (log-rank test, p Conclusions MAL2 is frequently overexpressed in ovarian carcinoma, and TPD52 overexpression is a favourable independent prognostic marker of potential value in the management of ovarian carcinoma patients.

In pediatric patients renal lymphoma frequently presents in the form of multiple, bilateral mass lesions, infrequently as a single or retroperitoneal mass, and rarely as diffuse infiltrative lesions. In patients with apparent central nervous system involvement close attention to other physical and laboratory findings are essential for preventing a delay in the final diagnosis. Herein we present a pediatric patient with renal lymphoma that presented with central nervous system findings that caused a delay in diagnosis. None declared.

lung transplantation (LTx) is a viable option for most patients with end-stage lung diseases. Esophageal motor disorders (EMD) are frequent in candidates for LTx, but there is very little data about changes in esophageal motility post-LTx. the aim of our study was to assess esophageal motor disorders by high resolution manometry (HRM) both pre-LTx and six months post-LTx in patients with and without organ rejection. HRM (Manoscan®) was performed in 57 patients both pre-LTx and six months post-LTx. HRM plots were analyzed according to the Chicago classification 3.0. EMD were found in 33.3% and in 49.1% of patients pre-LTx and post-LTx, respectively, and abnormal peristalsis was more frequently found post-LTx (p = 0.018). Hypercontractile esophagus was frequently found post-LTx (1.8% and 19.3% pre-LTx and post-LTx, respectively). Esophagogastric junction (EGJ) morphology changed significantly pre-LTx and post-LTx; type I (normal) was more frequent post-LTx (63-2% and 82.5% respectively, p = 0.007). EMD were more frequent post-LTx in both the non-rejection and rejection group, although particularly in the rejection group (43.2% and 69.2% respectively, p = 0.09). EMD such as distal spasm, hypercontractile esophagus and EGJ outflow obstruction were also observed more frequently post-LTx in the rejection group. significant changes in esophageal motility were observed pre-LTx and particularly post-LTx; hypercontractile esophagus was a frequent EMD found post-LTx. EMD were more frequent in the group of patients that experienced organ rejection compared to the non-rejection group. EMD leading to an impaired esophageal clearance should be considered as an additional factor that contributes to LTx failure.

Full Text Available Abstract Background Chronic heart failure (CHF is a major public health problem characterised by progressive deterioration with disabling symptoms and frequent hospital admissions. To influence hospitalisation rates it is crucial to identify precipitating factors. To characterise patients with CHF who seek an emergency department (ED because of worsening symptoms and signs and to explore the reasons why they are admitted to hospital. Method Patients (n = 2,648 seeking care for dyspnoea were identified at the ED, Sahlgrenska University Hospital/Östra. Out of 2,648 patients, 1,127 had a previous diagnosis of CHF, and of these, 786 were included in the present study with at least one sign and one symptom of worsening CHF. Results Although several of the patients wanted to go home after acute treatment in the ED, only 2% could be sent home. These patients were enrolled in an interventional study, which evaluated the acute care at home compared to the conventional, in hospital care. The remaining patients were admitted to hospital because of serious condition, including pneumonia/respiratory disease, myocardial infarction, pulmonary oedema, anaemia, the need to monitor cardiac rhythm, pathological blood chemistry and difficulties to communicate. Conclusion The vast majority of patients with worsening CHF seeking the ED required hospital care, predominantly because of co-morbidities. Patients with CHF with symptomatic deterioration may be admitted to hospital without additional emergency room investigations.

Digestive complications in enteral nutrition (EN) can negatively affect the nutrition clinical outcome of hospitalized patients. Diarrhea and constipation are intestinal motility disorders associated with pharmacotherapy, hydration, nutrition status, and age. The aim of this study was to analyze the frequency of these intestinal motility disorders in patients receiving EN and assess risk factors associated with diarrhea and constipation in hospitalized patients receiving exclusive EN therapy in a general hospital. The authors performed a sequential and observational study of 110 hospitalized adult patients fed exclusively by EN through a feeding tube. Patients were categorized according to the type of intestinal transit disorder as follows: group D (diarrhea, 3 or more watery evacuations in 24 hours), group C (constipation, less than 1 evacuation during 3 days), and group N (absence of diarrhea or constipation). All prescription drugs were recorded, and patients were analyzed according to the type and amount of medication received. The authors also investigated the presence of fiber in the enteral formula. Patients classified in group C represented 70% of the study population; group D comprised 13%, and group N represented 17%. There was an association between group C and orotracheal intubation as the indication for EN (P constipation (logistic regression analysis: P Constipation is more frequent than diarrhea in patients fed exclusively by EN. Enteral diet with fiber may protect against medication-associated intestinal motility disorders. The addition of prokinetic drugs seems to be useful in preventing constipation.

Patients with Crohn's disease (CD) are frequently exposed to diagnostic radiation, mainly as a result of abdominopelvic computed tomography (APCT) examinations. However, there are limited data on the impact of APCT on clinical management in this population. To investigate clinical predictors of urgent findings on APCT in patients with CD who presented to the emergency department (ED). A retrospective study was performed among patients with CD presenting to 11 EDs with a gastrointestinal complaint. The primary outcome, OPAN (obstruction, perforation, abscess, or non-CD-related urgent findings), included new or worsening CD-related urgent findings or non-CD-related urgent findings that required urgent or emergency treatment. Variables with P 100 beats/min (OR 2.33, 95 % CI 1.10-4.93), leukocyte count >10,000/mm(3) (OR 4.38, 95 % CI 2.10-9.13), and CRP >2.5 mg/dL (OR 3.11, 95 % CI 1.23-7.86) were identified as the independent predictors of OPAN, whereas biologic agent use (OR 0.37; 95 % CI 0.15-0.90) was identified as the negative predictor in patients with CD. Only 39 % of the APCTs performed in the ED among patients with CD showed urgent findings. Stricturing or penetrating disease, tachycardia, leukocytosis, and high CRP level were predictors of urgent CT findings, while biologic agent use was a negative predictor. To reduce unnecessary radiation exposure, the selection process for CD patients referred for APCT must be improved.

Full Text Available Abstract Epistaxis is an important otorhinolaryngological emergency, which usually has an apparent etiology, frequently local trauma in children. Here we present a case report wherein the epistaxis was recalcitrant, and proved to have a psychiatric disorder as an underlying basis. The child was diagnosed with Attention Deficit/Hyperactivity Disorder, hyperactive type, which led to trauma to nasal mucosa due to frequent and uncontrolled nose picking. Treatment with atomoxetine controlled the patient's symptoms and led to a remission of epistaxis.

Dementia with Lewy bodies (DLB) is a heterogeneous disease in which clinical presentation, symptoms, and evolution widely varies between patients. To investigate the existence of clinical subtypes in DLB based on the initial clinical presentation. 81 patients with a clinical diagnosis of probable DLB were consecutively included. All patients underwent a neurological evaluation including a structured questionnaire about neuropsychiatric symptoms and sleep, an assessment of motor impairment (Unified Parkinson Disease Rating Scale subscale III), and a formal neuropsychological evaluation. Onset of core symptoms (hallucinations, parkinsonism, and fluctuations) and dementia were systematically reviewed from medical records. We applied a K-means clustering method based on the initial clinical presentation. Cluster analysis yielded three different groups. Patients in cluster I (cognitive-predominant, n = 46) presented more frequently with cognitive symptoms (95.7%, n = 44, p presented more frequently with psychotic symptoms (77.3%, n = 17), and had a shorter duration until the onset of hallucinations (p clinical DLB can be defined when considering the differential initial presentations. The proposed subtypes have distinct clinical profiles and progression patterns.

Full Text Available Introduction: Acute exacerbations are a significant source of morbidity and mortality associated with chronic obstructive pulmonary disease (COPD. Some patients suffer an inordinate number of exacerbations while others remain relatively protected. The aim of this study was to evaluate the potentially modifiable precipitating parameters of frequent severe exacerbations requiring hospital admission in COPD. Materials and Methods: Consecutive patients admitted with acute exacerbation of COPD for a period of one year in a tertiary care hospital were evaluated prospectively. Data regarding the number of exacerbations in the previous year, current comorbidities, medications, and clinical and functional status of COPD patients were evaluated. Results: We included 98 COPD patients (81.63% men admitted consecutively with exacerbations in our department. The mean number of severe exacerbations was (2.42 per patient/per year, and 65% of the patients had frequent severe exacerbations. Multivariate analysis indicated that serum uric acid, serum total IgE, depression and anxiety, gastroesophageal reflux disease symptoms, air pollution, poor adherence to inhaled therapy, and irregular outpatient followup visits were independent predictors of frequent severe exacerbations. Conclusion: COPD patients with frequent exacerbations should be carefully assessed for modifiable confounding risk factors regardless of poor lung function to decrease exacerbation frequency and related poor prognosis. Raised serum total IgE levels may point towards atopy as an additional comorbidity in COPD while uric acid can have a clinically useful role in risk stratification in a primary care setting.

We set out to define the relative prevalence and common presentations of the various aetiologies of headache within an ambulant HIV-seropositive adult population in Kampala, Uganda. We conducted a prospective study of adult HIV-1-seropositive ambulatory patients consecutively presenting with new onset headaches. Patients were classified as focal-febrile, focal-afebrile, non-focal-febrile or non-focal-afebrile, depending on presence or absence of fever and localizing neurological signs. Further management followed along a pre-defined diagnostic algorithm to an endpoint of a diagnosis. We assessed outcomes during four months of follow up. One hundred and eighty patients were enrolled (72% women). Most subjects presented at WHO clinical stages III and IV of HIV disease, with a median Karnofsky performance rating of 70% (IQR 60-80).The most common diagnoses were cryptococcal meningitis (28%, n = 50) and bacterial sinusitis (31%, n = 56). Less frequent diagnoses included cerebral toxoplasmosis (4%, n = 7), and tuberculous meningitis (4%, n = 7). Thirty-two (18%) had other diagnoses (malaria, bacteraemia, etc.). No aetiology could be elucidated in 28 persons (15%). Overall mortality was 13.3% (24 of 180) after four months of follow up. Those without an established headache aetiology had good clinical outcomes, with only one death (4% mortality), and 86% were ambulatory at four months. In an African HIV-infected ambulatory population presenting with new onset headache, aetiology was found in at least 70%. Cryptococcal meningitis and sinusitis accounted for more than half of the cases.

Patients receiving hemodialysis often perceive their caregivers are overburdened. We hypothesize that increasing hemodialysis frequency would result in higher patient perceptions of burden on their unpaid caregivers. In two separate trials, 245 patients were randomized to receive in-center daily hemodialysis (6 days/week) or conventional hemodialysis (3 days/week) while 87 patients were randomized to receive home nocturnal hemodialysis (6 nights/week) or home conventional hemodialysis for 12 months. Changes in overall mean scores over time in the 10-question Cousineau perceived burden scale were compared. In total, 173 of 245 (70%) and 80 of 87 (92%) randomized patients in the Daily and Nocturnal Trials, respectively, reported having an unpaid caregiver at baseline or during follow-up. Relative to in-center conventional dialysis, the 12-month change in mean perceived burden score with in-center daily hemodialysis was -2.1 (95% confidence interval, -9.4 to +5.3; P=0.58). Relative to home conventional dialysis, the 12-month change in mean perceived burden score with home nocturnal dialysis was +6.1 (95% confidence interval, -0.8 to +13.1; P=0.08). After multiple imputation for missing data in the Nocturnal Trial, the relative difference between home nocturnal and home conventional hemodialysis was +9.4 (95% confidence interval, +0.55 to +18.3; P=0.04). In the Nocturnal Trial, changes in perceived burden were inversely correlated with adherence to dialysis treatments (Pearson r=-0.35; P=0.02). Relative to conventional hemodialysis, in-center daily hemodialysis did not result in higher perceptions of caregiver burden. There was a trend to higher perceived caregiver burden among patients randomized to home nocturnal hemodialysis. These findings may have implications for the adoption of and adherence to frequent nocturnal hemodialysis.

Brain perfusion SPECT in children with frequent fits

International Nuclear Information System (INIS)

Heiskala, H.; Launes, J.; Pihko, H.; Nikkinen, P.; Santavuori, P.

1993-01-01

We studied 14 children with frequent fits using 99m Tc-HM-PAO single photon emission computed tomography (SPECT). There were 11 patients with partial secondary generalized epilepsy (PSGE) and 3 with Lennox-Gastaut syndrome (LGS). The typical regional cerebral blood flow (rCBF) finding in PSGE was a single area of abnormally low perfused cortex, and that in LGS, multiple hypoperfused areas. Clinically, the LGS patients were more severely affected. SPECT was more sensitive in detecting abnormalities than EEG, CT or MRI. Extensive impairment of rCBF may thus indicate unfavourable development of intellectual performance and poor seizure control. (author)

The most common such condition is HIV-1-associated myelopathy (HAM which characteristically seen during advanced HIV infection in patients with low CD4 cell counts and previous AIDS-defining diagnoses. Histologically seen in approximately 30% of AIDS patients, but only 10% have clinical symptoms related to the disease. We describe an unusual case of HAM in previously asymptomatic patient with relatively low CD4 cell count (78 cells/mm3. The patient unaware of her seropositive status presented with a clinically slowly progressive myelopathy with difficulty in walking without assistance. We discharged a patient on antiretroviral therapy. We also review the disorders reported to derange spinal cord function in previously asymptomatic HIV-1 infected patients with preserved counts.

Alagille syndrome is a multisystem disorder characterized by highly variable expressivity, most frequently caused by heterozygous JAG1 gene mutations. Classic diagnostic criteria combine the presence of bile duct paucity on liver biopsy with three of five systems affected; liver, heart, skeleton, eye and dysmorphic facies. The aim of this study was to determine the prevalence and distribution of JAG1 mutations in patients referred for routine clinical diagnostic testing. Clinical data were available for 241 patients from 135 families. The index cases were grouped according to the number of systems affected (heart, liver, skeletal, eye and facies) and the mutation frequency calculated for each group. JAG1 mutations were identified in 59/135 (44%) probands. The highest mutation detection rates were observed in patients with the most frequent presenting features of Alagille syndrome; ranging from 20% (one system) to 86% (five systems). The overall mutation pick-up rate in a clinical diagnostic setting was lower than in previous research studies. Identification of a JAG1 gene mutation is particularly useful for those patients with atypical or mild Alagille syndrome who do not meet classic diagnostic criteria as it provides a definite molecular diagnosis and allows accurate genetic counselling for the family. © 2011 John Wiley & Sons A/S.

José Hernán Martínez

2013-01-01

Full Text Available Diabetic myonecrosis is a frequently unrecognized complication of longstanding and poorly controlled diabetes mellitus. The clinical presentation is swelling, pain, and tenderness of the involved muscle, most commonly the thigh muscles. Management consists of conservative measures including analgesia and rest. Short-term prognosis is good, but long-term prognosis is poor with most patients dying within 5 years. Failure to properly identify this condition will expose the patient to aggressive measures that could result in increased morbidity. To our knowledge this is the first case reported in which there was involvement of multiple muscle groups including upper and lower limbs.

Introduction: amoebic hepatic abscess is the extraintestinal manifestation of an infection by entamoeba histolytica. Estimations are made that 10% of the world population has been infected by the parasite, being more frequent in tropical regions, where overcrowding and bad sanitary conditions occur. Africa, Latin America, Southeast Asian and India have considerable health problems, resulting from this disease. In Cuba amoebiasis has been proved not to be one of the most frequent parasitism cases. Case presentation: male patient of age 48 years and of Indian nationality, presenting clinical findings, which proves a unique lesion in the right liver lobule, diagnosed by ultrasound scan and nuclear magnetic resonance. The presence is confirmed of serum antibodies against entamoeba histolytica. Treatment with metronidazole produced clinical and radiological improvement. Conclusions: atypical clinical presentation constitutes a remarkable element worthy considered in daily clinical practice. (author)

Nodal marginal zone lymphoma (NMZL) is a rare type of B-cell non-Hodgkin lymphoma. This study assessed the clinical features of 56 patients with NMZL in comparison to 46 patients with follicular lymphoma (FL). Patients with NMZL and FL had a largely similar clinical presentation, but patients with FL had a higher disease stage at presentation, more frequent abdominal lymphadenopathy and bone marrow involvement, and showed more common transformation into diffuse large B-cell lymphoma (DLBCL) during the course of disease. Overall survival and event-free survival were similar for patients with NMZL and FL, but factors associated with worse prognosis differed between the two groups. Transformation into DLBCL was associated with a significantly poorer outcome in both groups, but the phenotypes were different: DLBCL arising in FL was mainly of germinal center B-cell phenotype, whereas DLBCL arising in NMZL was mainly of non-germinal center B-cell phenotype.

Full Text Available Abstract Background There is a need for assistance from primary care mental health workers in general practice in the Netherlands. General practitioners (GPs experience an overload of frequent attenders suffering from psychological problems. Problem Solving Treatment (PST is a brief psychological treatment tailored for use in a primary care setting. PST is provided by nurses, and earlier research has shown that it is a treatment at least as effective as usual care. However, research outcomes are not totally satisfying. This protocol describes a randomized clinical trial on the effectiveness of PST provided by nurses for patients in general practice. The results of this study, which currently being carried out, will be presented as soon as they are available. Methods/design This study protocol describes the design of a randomized controlled trial to investigate the effectiveness and cost-effectiveness of PST and usual care compared to usual care only. Patients, 18 years and older, who present psychological problems and are frequent attenders in general practice are recruited by the research assistant. The participants receive questionnaires at baseline, after the intervention, and again after 3 months and 9 months. Primary outcome is the reduction of symptoms, and other outcomes measured are improvement in problem solving skills, psychological and physical well being, daily functioning, social support, coping styles, problem evaluation and health care utilization. Discussion Our results may either confirm that PST in primary care is an effective way of dealing with emotional disorders and a promising addition to the primary care in the UK and USA, or may question this assumption. This trial will allow an evaluation of the effects of PST in practical circumstances and in a rather heterogeneous group of primary care patients. This study delivers scientific support for this use and therefore indications for optimal treatment and referral.

The Q-switched 1064-nm neodymium-doped yttrium aluminum garnet (QS 1064-nm Nd:YAG) laser is increasingly used for nonablative skin rejuvenation or "laser toning" for melasma. Multiple and frequent low-fluence, large-spot-size treatments are used to achieve laser toning, and these treatments are associated with the development of macular hypopigmentation as a complication. We present a case series of three patients who developed guttate hypomelanotic macules on the face after receiving laser toning treatment with QS 1064-nm Nd:YAG.

Full Text Available INTRODUCTION: Several aspects of gastroesophageal reflux disease (GERD have been studied, but the frequency of comorbidities is not yet fully understood. OBJECTIVES: To study the prevalence of GERD comorbidities in a tertiary care hospital. METHODS: We prospectively studied 670 consecutive adult patients from the outpatient department of our facility. A diagnosis was established using clinical, endoscopic and/or pHmetry-related findings. Each patient's medical file was reviewed with respect to the presence of other medical conditions and diagnoses. RESULTS: Of the 670 patients, 459 (68.6% were female, and the mean age was 55.94 (17-80 years. We registered 316 patients (47.1% with the erosive form of GERD and 354 patients (52.9% with the non-erosive form. A total of 1,664 instances of comorbidities were recorded in 586 patients (87.5%, with the most common being arterial hypertension (21%, hypercholesterolemia (9%, obesity (9%, type II diabetes mellitus (5% and depression (4%. Two or more comorbidities were present in 437 individuals (64.8%. The occurrence of comorbidities increased with age and was higher in patients with the non-erosive form of GERD. CONCLUSIONS: In a tertiary referral population, comorbidities were very common, and these may have worsened the already impaired health-related quality of life of these patients. Clinicians caring for GERD patients in this setting must be aware of the likelihood and nature of comorbid disorders and their impact on disease presentation and patient management.

In Oslo, the majority of patients with acute poisoning are treated in primary care, at an emergency outpatient clinic with limited diagnostic and treatment resources. We describe the poisonings currently seen in this setting. We compare our findings with previous studies, with special concern for the appearance of new toxic agents, and changes in overall numbers and patterns of poisoning. Observational study. Patients above the age of 12 years presenting at Oslo Accident and Emergency Outpatient Clinic (Oslo Legevakt) with acute poisoning were included consecutively from October 2011 through September 2012. Physicians and nurses registered data on preset forms. Main outcome measures were toxic agents, age, sex, intention, referral and time of presentation. There were 2923 episodes of acute poisoning in 2261 patients. Median age of the patients was 32 years, and 1430 (63%) were males. The most frequent toxic agents were ethanol in 1684 (58%) episodes, heroin in 542 (19 %), benzodiazepines in 521 (18%), amphetamine in 275 (9%), fire smoke in 192 (7%), gamma-hydroxybutyrate (GHB) in 144 (5%), and cannabis in 143 (5%). In 904 (31%) poisonings there were more than one toxic agent. In 493 episodes (17%), the patient was hospitalised, and in 60 episodes (2%) admitted to a psychiatric ward. Most poisonings, 2328 (80%), were accidental overdoses with substances of abuse, 276 (9%) were suicide attempts, and 312 (11%) were accidents. Among ethanol poisonings in patients above the age of 26 years, 685/934 (73%) were in males, and 339/934 (36%) presented during weekends. However, among ethanol poisonings in patients under the age of 26 years, 221/451 (49 ) were in females, and 297/451 (66%) presented during weekends. The poisonings treated in this primary care setting were mostly due to accidental overdoses with ethanol or other substances of abuse. There is a disconcerting weekend drinking pattern among adolescents and young adults, with young females presenting as often as

Seasonal variations in cardiovascular disease is well recognized. However, little is known about the presentations and outcomes of Japanese heart failure (HF) patients in the winter season. We used a single hospital-based cohort from the Shinken Database 2004-2012, comprising all new patients (n=19,994) who visited the Cardiovascular Institute Hospital. A total of 375 patients who were admitted owing to acute decompensated HF were included in the analysis. Of these patients, 136 (36%) were admitted in winter. Winter was defined as the period between December and February. The HF patients admitted in winter were older, and had a higher prevalence of hypertension and diabetes mellitus than the patients admitted in other seasons. Patients with conditions categorized as clinical scenario 1 tended to be admitted more commonly in winter. HF with preserved left ventricular ejection fraction (LVEF) was more common in HF patients admitted in winter than in those admitted in other seasons. Beta-blocker use at hospital discharge was more common in the patients admitted in other seasons. Kaplan-Meier curves and log-rank test results indicated that the incidences of all-cause death, cardiovascular death, and HF admission were comparable between the patients admitted in winter and those admitted in other seasons. HF admission was frequently observed in the winter season and HF patients admitted in the winter season were older, and had higher prevalence of hypertension and diabetes mellitus, and preserved LVEF suggesting that we might need to pay more attention for elderly patients with hypertension, diabetes mellitus, and HF with preserved LVEF to decrease HF admissions in the winter season.

2017-04-26

The understanding of various health-oriented vital sign data generated from body sensor networks (BSNs) and discovery of the associations between the generated parameters is an important task that may assist and promote important decision making in healthcare. For example, in a smart home scenario where occupants' health status is continuously monitored remotely, it is essential to provide the required assistance when an unusual or critical situation is detected in their vital sign data. In this paper, we present an efficient approach for mining the periodic patterns obtained from BSN data. In addition, we employ a correlation test on the generated patterns and introduce productive-associated periodic-frequent patterns as the set of correlated periodic-frequent items. The combination of these measures has the advantage of empowering healthcare providers and patients to raise the quality of diagnosis as well as improve treatment and smart care, especially for elderly people in smart homes. We develop an efficient algorithm named PPFP-growth (Productive Periodic-Frequent Pattern-growth) to discover all productive-associated periodic frequent patterns using these measures. PPFP-growth is efficient and the productiveness measure removes uncorrelated periodic items. An experimental evaluation on synthetic and real datasets shows the efficiency of the proposed PPFP-growth algorithm, which can filter a huge number of periodic patterns to reveal only the correlated ones.

Full Text Available Objective: Hirsutism, similar to men, is the presence of terminal hairs in androgen-to sensitive areas in women. The present report aimed to study etiology and determine the prevalence of the diseases that causes hirsutism in these patients. Methods: In this study, total number of 40 patients who admitted because of hirsutism to Department of Endocrinology and Metabolism clinic was enrolled. Demographic, clinical and laboratory parameters of the patients were evaluated. Results: Result of the study showed that polycystic ovary syndrome is the most common cause of hirsutism. The second most common cause was found as idiopathic hirsutism. Conclusion: By the present study, etiologic factors of hirsutism were examined firstly in our region in which Ethnic and cultural diversity is concentrated. In rare cases like Cushing's syndrome, hyperprolactinemia, non-classic adrenal hyperplasia, androgen-secreting tumors should be considered in the differential diagnosis of hirsutism.

Oral squamous cell carcinoma (OSCC) are amongst commonest cancer in the Indian sub-continent. After treatment, these patients require frequent followup to look for recurrences/second primary. Mouth Self Examination (MSE) has a great potential in all levels of prevention of oral cancer. However, the compliance to self-examination has been reported as poor. Mobile phone is a cheap and effective way to reach out to people. Short Message Service (SMS) is extremely popular can be a very effective motivational and interactive tool in health care setting. We aimed to identify in adequately treated OSCC patients, the influence of health provider initiated SMS on the compliance to the MSE and to establish the efficacy of MSE by comparing patients' MSE interpretation via replies to the SMS with that of the experts' opinion on clinical examination status during follow up. We conclude that MSE can be very useful in adequately treated OSCC patients for evaluating disease status. All treated OSCC patients must be adequately educated for MSE as an integral part of treatment & follow-up protocol by the health provider facility. Health provider generated SMS reminders do improve motivation and compliance towards MSE but don't seem to reduce dropouts in follow up for large and diverse population like that in India.

Invasive meningococcal disease (IMD) is recognized as septicemia and/or meningitis. However, early symptoms may vary and are frequently nonspecific. Early abdominal presentations have been increasingly described. We aimed to explore a large cohort of patients with initial abdominal presentations for association with particular meningococcal strains. Confirmed IMD cases in France between 1991-2016 were screened for the presence within the 24 hours before diagnosis of at least one of the following criteria (1) abdominal pain, (2) gastro-enteritis with diarrhea and vomiting, (3) diarrhea only. Whole genome sequencing was performed on all cultured isolates. We identified 105 cases (median age 19 years) of early abdominal presentations with a sharp increase since 2014. Early abdominal pain alone was the most frequent symptom (n=67, 64%), followed by gastro-enteritis (n=26, 25%) and diarrhea alone (n=12, 11%). Twenty patients (20%) had abdominal surgery. A higher case fatality rate (24%) was observed in these cases compared to 10.4% in all IMD in France (p=0.007) with high levels of inflammation markers in the blood. Isolates of group W were significantly more predominant in these cases compared to all IMD. Most of these isolates belonged to clonal complex ST-11 (cc11) of the sublineages of the South American-UK strain. Abdominal presentations are frequently provoked by hyperinvasive isolates of meningococci. Delay in the management of these cases and the virulence of the isolates may explain the high fatality rate. Rapid recognition is a key element to improve their management.

Frequent methodological errors in clinical research.

Silva Aycaguer, L C

2018-03-07

Several errors that are frequently present in clinical research are listed, discussed and illustrated. A distinction is made between what can be considered an "error" arising from ignorance or neglect, from what stems from a lack of integrity of researchers, although it is recognized and documented that it is not easy to establish when we are in a case and when in another. The work does not intend to make an exhaustive inventory of such problems, but focuses on those that, while frequent, are usually less evident or less marked in the various lists that have been published with this type of problems. It has been a decision to develop in detail the examples that illustrate the problems identified, instead of making a list of errors accompanied by an epidermal description of their characteristics.

Frequent activation of EGFR in advanced chordomas

Directory of Open Access Journals (Sweden)

Dewaele Barbara

2011-07-01

Full Text Available Abstract Background Chordomas are rare neoplasms, arising from notochordal remnants in the midline skeletal axis, for which the current treatment is limited to surgery and radiotherapy. Recent reports suggest that receptor tyrosine kinases (RTK might be essential for the survival or proliferation of chordoma cells, providing a rationale for RTK targeted therapy. Nevertheless, the reported data are conflicting, most likely due to the assorted tumor specimens used for the studies and the heterogeneous methodological approaches. In the present study, we performed a comprehensive characterization of this rare entity using a wide range of assays in search for relevant therapeutic targets. Methods Histopathological features of 42 chordoma specimens, 21 primary and 21 advanced, were assessed by immunohistochemistry and fluorescent in situ hybridization (FISH using PDGFRB, CSF1R, and EGFR probes. Twenty-two of these cases, for which frozen material was available (nine primary and 13 advanced tumors, were selectively analyzed using the whole-genome 4.3 K TK-CGH-array, phospho-kinase antibody array or Western immunoblotting. The study was supplemented by direct sequencing of KIT, PDGFRB, CSF1R and EGFR. Results We demonstrated that EGFR is frequently and the most significantly activated RTK in chordomas. Furthermore, concurrent to EGFR activation, the tumors commonly reveal co-activation of alternative RTK. The consistent activation of AKT, the frequent loss of the tumor suppressor PTEN allele, the recurrent activation of upstream RTK and of downstream effectors like p70S6K and mTOR, all indicate the PI3K/AKT pathway as an important mediator of transformation in chordomas. Conclusions Given the complexity of the signaling in chordomas, combined treatment regimens targeting multiple RTK and downstream effectors are likely to be the most effective in these tumors. Personalized therapy with careful selection of the patients, based on the molecular profile of

Lichenoid keratosis (LK), also known as benign lichenoid keratosis or lichen planus-like keratosis, is a solitary, pink to red-brown scaly plaque representing a host immunological response to a variety of precursor lesions. LK is often misdiagnosed as a dermatological malignancy owing to its clinical resemblance to basal cell carcinoma (BCC) or Bowen disease. We performed a retrospective analysis of the pathology records of a series of LK lesions with reference to the demographic features and accuracy of clinical diagnosis. The pathology records from 2008 to 2009 of 263 consecutive patients with a histological diagnosis of LK from a specialized skin laboratory were retrieved. Data relating to clinical diagnosis, age, sex, anatomical location, time of year of presentation and any coexistent pathological lesions adjacent to the LK were recorded. Mean age at presentation was 64 years (range 34-96), and 58% of patients were female. The most common anatomical site was the chest/anterior torso, followed by the back and legs. The most common coexisting lesion was solar keratosis at 14%, followed by seborrhoeic keratosis (SK) at 7.8%. The correct clinical diagnosis of LK was made in 29.5% of cases. The most common clinical diagnosis was BCC (47%), while SK was the preferred diagnosis in 18%. A clinical diagnosis was not given in 5.5% of cases. In conclusion, it appears that LK is frequently misdiagnosed, with misdiagnosis occurring in > 70% of cases in this study. © 2017 British Association of Dermatologists.

Repeated exposure to occupational ergonomic hazards, such as frequent exertion (repetitive bending or twisting) and frequent standing, can lead to injuries, most commonly musculoskeletal disorders (1). Work-related musculoskeletal disorders have been estimated to cost the United States approximately $2.6 billion in annual direct and indirect costs (2). A recent literature review provided evidence that prolonged standing at work also leads to adverse health outcomes, such as back pain, physical fatigue, and muscle pain (3). To determine which industry and occupation groups currently have the highest prevalence rates of frequent exertion at work and frequent standing at work, CDC analyzed data from the 2015 National Health Interview Survey (NHIS) Occupational Health Supplement (OHS) regarding currently employed adults in the United States. By industry, the highest prevalence of both frequent exertion and frequent standing at work was among those in the agriculture, forestry, fishing, and hunting industry group (70.9%); by occupation, the highest prevalence was among those in the construction and extraction occupation group (76.9%). Large differences among industry and occupation groups were found with regard to these ergonomic hazards, suggesting a need for targeted interventions designed to reduce workplace exposure.

Full Text Available Abstract Background A small percentage of high-risk patients accounts for a large proportion of Medicaid spending in the United States, which has become an urgent policy issue. Our objective was to pilot a novel patient-centered intervention for high-risk patients with frequent hospital admissions to determine its potential to improve care and reduce costs. Methods Community and hospital-based care management and coordination intervention with pre-post analysis of health care utilization. We enrolled Medicaid fee-for-service patients aged 18-64 who were admitted to an urban public hospital and identified as being at high risk for hospital readmission by a validated predictive algorithm. Enrolled patients were evaluated using qualitative and quantitative interview techniques to identify needs such as transportation to/advocacy during medical appointments, mental health/substance use treatment, and home visits. A community housing partner initiated housing applications in-hospital for homeless patients. Care managers facilitated appropriate discharge plans then worked closely with patients in the community using a harm reduction approach. Results Nineteen patients were enrolled; all were male, 18/19 were substance users, and 17/19 were homeless. Patients had a total of 64 inpatient admissions in the 12 months before the intervention, versus 40 in the following 12 months, a 37.5% reduction. Most patients (73.3% had fewer inpatient admissions in the year after the intervention compared to the prior year. Overall ED visits also decreased after study enrollment, while outpatient clinic visits increased. Yearly study hospital Medicaid reimbursements fell an average of $16,383 per patient. Conclusions A pilot intervention for high-cost patients shows promising results for health services usage. We are currently expanding our model to serve more patients at additional hospitals to see if the pilot's success can be replicated. Trial registration

Full Text Available Background and Aims. Complementary and alternative medicine (CAM is commonly used among patients with inflammatory bowel diseases (IBD, but evidence about its real-life use is limited. We aimed to assess and compare CAM use in outpatients with IBD and other gastrointestinal diseases. Materials and Methods. The use of herbs and botanicals, lifestyle modifications and mind/body therapies, patient satisfaction, and continuous use of conventional medicine were assessed with an anonymous questionnaire at a tertiary IBD unit in Hungary. 396 IBD patients (207 with Crohn’s disease, 185 with ulcerative colitis, and 4 with indeterminate colitis and 164 patients with gastric acid-related diseases, premalignant and malignant colorectal diseases, lactose intolerance, celiac disease, dysbacteriosis, and so on were included. Results. IBD patients reported significantly lower usage of herbs than did controls (25% versus 42%, p<0.001. More than 90% of responding IBD patients continued conventional medication besides herbal remedies (83% in unaltered doses. IBD patients were more likely to implement lifestyle modifications (77% versus 63%, p=0.0011, but not body/mind therapies (20% versus 15%, p=0.1516. Younger age was a significant predictor of lifestyle modifications (p=0.0246. Conclusions. CAM use (especially that of herbal remedies in IBD is less frequent than that in other gastrointestinal diseases. It is more a complementary than an alternative to conventional medicine in IBD. There is no significant difference between CAM use in patients with Crohn’s disease and that in patients with ulcerative colitis, although the latter tend to choose herbs; the benefit of which is supported by scientific evidence.

Extra-hepatic spread is present in 5% to 15% of patients with hepatocellular carcinoma (HCC) at the time of diagnosis. The most frequent sites are lung and regional lymph nodes. Here, we report 3 cases of unsuspected HCC with symptoms due to bone lesions as initial presentation. Morphological characteristics and immunohistochemistry from the examined bone were the key data for diagnosis. None of the patients had an already known chronic liver disease. Differential diagnoses with HCC upon ectopic liver disease or hepatoid adenocarcinoma were shown. Therapy with the orally active multikinase inhibitor sorafenib plus symptomatic treatment was indicated.

Diarrhea is an increasingly frequent clinical finding in Swiss medical practice. One reason is the volume of tourism in countries with different climatic and social circumstances. To obtain an overview of the enteropathogenic bacteria spectrum as a cause of diarrhea, we analyzed 11,163 stool specimens from a representative group of patients throughout Switzerland. Enteropathogenic bacteria were found in 15.2% of all specimens; 50% were Campylobacter jejuni/coli, 35% Salmonella spp., 8% Aeromonas hydrophila group, 4% Shigella spp. and 3% Yersinia enterocolitica. This distribution is taken for all age groups and for both sexes. In the infant age there was a maximum evidence of enteropathogenic bacteria of the female sex. In childhood this maximum concerned to the male sex. Patients older than fifty had no positive stool specimens. As expected the most frequent positive stool specimens were in summer.

The four-transmembrane MAL2 protein is frequently overexpressed in breast carcinoma, and MAL2 overexpression is associated with gain of the corresponding locus at chromosome 8q24.12. Independent expression microarray studies predict MAL2 overexpression in ovarian carcinoma, but these had remained unconfirmed. MAL2 binds tumor protein D52 (TPD52), which is frequently overexpressed in ovarian carcinoma, but the clinical significance of MAL2 and TPD52 overexpression was unknown. Immunohistochemical analyses of MAL2 and TPD52 expression were performed using tissue microarray sections including benign, borderline and malignant epithelial ovarian tumours. Inmmunohistochemical staining intensity and distribution was assessed both visually and digitally. MAL2 and TPD52 were significantly overexpressed in high-grade serous carcinomas compared with serous borderline tumours. MAL2 expression was highest in serous carcinomas relative to other histological subtypes, whereas TPD52 expression was highest in clear cell carcinomas. MAL2 expression was not related to patient survival, however high-level TPD52 staining was significantly associated with improved overall survival in patients with stage III serous ovarian carcinoma (log-rank test, p < 0.001; n = 124) and was an independent predictor of survival in the overall carcinoma cohort (hazard ratio (HR), 0.498; 95% confidence interval (CI), 0.34-0.728; p < 0.001; n = 221), and in serous carcinomas (HR, 0.440; 95% CI, 0.294-0.658; p < 0.001; n = 182). MAL2 is frequently overexpressed in ovarian carcinoma, and TPD52 overexpression is a favourable independent prognostic marker of potential value in the management of ovarian carcinoma patients

Full Text Available The use of simple and economic tests to rule out diseases of sufficient clinical severity is appealing in emergency department (ED, since it would be effective for contrasting ED overcrowding and decreasing healthcare costs. The aim of this study was to assess the diagnostic performance of simple and economic haematological testing in a large sample of adult patients presenting at the ED of the Academic Hospital of Parma during the year 2010 with the five most frequent acute pathologies (i.e., acute myocardial infarction, renal colic, pneumonia, trauma and pancreatitis. Both leukocyte count and hemoglobin showed a good diagnostic performance (Area Under the Curve [AUC] of 0.85 for leukocyte count and 0.76 for hemoglobin; both p < 0.01. Although the platelet count was significantly increased in all patients groups except pancreatitis, the diagnostic performance did not achieve statistical significance (AUC 0.53; p = 0.07. We also observed an increased RDW in all groups, except in those with trauma and the diagnostic performance was acceptable (AUC 0.705; p < 0.01. The mean platelet volume (MPV was consistently lower in all patients groups and also characterized by an efficient diagnostic performance (AUC 0.76; p < 0.01. This evidence led us to design an arbitrary formula, whereby MPV and hemoglobin were multiplied, and further divided by the leukocyte count, obtaining a remarkable AUC (0.91; p < 0.01. We conclude that simple, rapid and cheap hematological tests might provide relevant clinical information for decision making to busy emergency physicians, and the their combination into an arbitrary formula might further increase the specific diagnostic potential of each of them.

Essouissi, Imen

2006-01-01

Mental Retardation (MR) is the most frequent handicap. It touches 3% of the general population. The genetic causes of this handicap account for 40% of these cases. ARX gene (Aristaless related homeobox gene) belongs to the family of the genes homeobox located in Xp22.1. It is considered as the most frequently muted gene after the FMR1 gene. It is implicated in various forms of syndromic and nonsyndromic MR. Several types of mutation were identified on the level of this gene, including deletions/insertions, duplications, missense and nonsense mutations, responsible for a wide spectrum of phenotypes. The goal of this work is to seek the most frequent change of gene ARX: duplication 24pb (at the origin of an expansion of the field poly has protein ARX in the position 144-155AA) among Tunisian boys presenting in particular family forms of non specific MR, sporadic forms of non specific MR like certain patients presenting a West syndrome.To prove the duplication of 24 Pb, we used in this work the Pcr technique. The change of duplication 24pb was not found in our series, this could be explained by the low number of cases family studied (38 families) and by the absence of connection studies accusing a mode of transmission related to X chromosome in particular for the sporadic cases.

Altered gene expression in blood and sputum in COPD frequent exacerbators in the ECLIPSE cohort.

Directory of Open Access Journals (Sweden)

Dave Singh

Full Text Available Patients with chronic obstructive pulmonary disease (COPD who are defined as frequent exacerbators suffer with 2 or more exacerbations every year. The molecular mechanisms responsible for this phenotype are poorly understood. We investigated gene expression profile patterns associated with frequent exacerbations in sputum and blood cells in a well-characterised cohort. Samples from subjects from the ECLIPSE COPD cohort were used; sputum and blood samples from 138 subjects were used for microarray gene expression analysis, while blood samples from 438 subjects were used for polymerase chain reaction (PCR testing. Using microarray, 150 genes were differentially expressed in blood (>±1.5 fold change, p≤0.01 between frequent compared to non-exacerbators. In sputum cells, only 6 genes were differentially expressed. The differentially regulated genes in blood included downregulation of those involved in lymphocyte signalling and upregulation of pro-apoptotic signalling genes. Multivariate analysis of the microarray data followed by confirmatory PCR analysis identified 3 genes that predicted frequent exacerbations; B3GNT, LAF4 and ARHGEF10. The sensitivity and specificity of these 3 genes to predict the frequent exacerbator phenotype was 88% and 33% respectively. There are alterations in systemic immune function associated with frequent exacerbations; down-regulation of lymphocyte function and a shift towards pro-apoptosis mechanisms are apparent in patients with frequent exacerbations.

Vestibular symptoms (VSs) are frequent complaints in patients attending ambulatory care and the emergency room. They may represent a peripheral vestibular disorder or a stroke/transient ischemic attack (TIA), yet many patients have VSs that cannot be clearly classified at presentation. This study aims to characterize and determine the long-term prognosis of these patients. In a prospective community-based study involving 104,700 individuals registered at 4 health centers of Northern Portugal, patients with a first-ever-in-lifetime focal neurologic symptom (FNS) were ascertained using comprehensive methods, including referrals from physicians working in the study area and data retrieved from emergency/discharge records. Physicians were encouraged to report/notify any patient who might have experienced an FNS, including those with vertigo or vertigo-like symptoms, imbalance, presyncope, or nonspecific dizziness. After neurologic assessment patients were classified as having a peripheral vestibular symptom (pVS), a stroke/TIA, or an unclassified vestibular symptom (uVS). They were followed up 7 years after the index event at the outpatient clinic; predictors of survival free from stroke or vascular events were determined using Cox proportional hazards models. Of the 1163 patients with an FNS, 360 (31.0%) were included, 16.7% had a stroke/TIA, 57.8% had pVS, and 25.6% had uVS. Most patients presented only isolated VSs (62.8%); 63% were women and mean age was 60.1 years (standard deviation = 16); hypertension (47.8%), hypercholesterolemia (41.9%), and diabetes (19.2%) were the most prevalent vascular risk factors (VRFs). Cranial computed tomography (CT) scan was performed in 63.3%. Adjusting for age, sex, VRFs, and diagnosis (TIA, pVS and uVS), the long-term risk of stroke was higher when CT showed silent infarctions (hazard rate [HR] = 3.96; 95% confidence interval [CI], 1.63-9.60) and the risk of vascular events (stroke, myocardial infarction, or vascular death) was

Measurement of agitation and aggression in adult and aged neuropsychiatric patients: review of definitions and frequently used measurement scales.

Agitation and aggression in adult psychiatric patients with psychoses and in persons with dementia increase the burden of disease and frequently cause hospitalization. The implementation of currently available management strategies and the development of new ones is hindered by inconsistent terminology that confuses agitation with aggression. This confusion is maintained by many rating scales that fail to distinguish between these two syndromes. We review the frequently used rating scales with a particular focus on their ability to separate agitation from aggression. Agitation and aggression are two different syndromes. For example, reactive aggression is often precipitated by rejection of care and may not be associated with agitation per se. We propose, in treatment studies of behavioral symptoms of dementia and challenging behaviors in psychoses, that outcomes should be evaluated separately for agitation and aggression. This is important for investigation of drug effectiveness since the medication may be effective against one syndrome but not the other. Separate assessments of agitation and aggression should be a general principle of trial design with particular salience for registration studies of medications proposed for approval by the U.S. Food and Drug Administration and other regulatory bodies.

Full Text Available Introduction: Oral squamous cell carcinoma (OSCC are amongst commonest cancer in the Indian sub-continent. After treatment, these patients require frequent followup to look for recurrences/second primary. Mouth Self Examination (MSE has a great potential in all levels of prevention of oral cancer. However, the compliance to self-examination has been reported as poor. Mobile phone is a cheap and effective way to reach out to people. Short Message Service (SMS is extremely popular can be a very effective motivational and interactive tool in health care setting. Methodology: We aimed to identify in adequately treated OSCC patients, the influence of health provider initiated SMS on the compliance to the MSE and to establish the efficacy of MSE by comparing patients' MSE interpretation via replies to the SMS with that of the experts' opinion on clinical examination status during follow up. Conclusion: We conclude that MSE can be very useful in adequately treated OSCC patients for evaluating disease status. All treated OSCC patients must be adequately educated for MSE as an integral part of treatment & follow-up protocol by the health provider facility. Health provider generated SMS reminders do improve motivation and compliance towards MSE but don't seem to reduce dropouts in follow up for large and diverse population like that in India.

The use of health services has seen a steep rise. The frequent users are responsible for significant economic, human and social impact. The objective is to analyze the characteristics of frequent attenders in our Health Center, in order to evaluate the possibility of taking corrective measures to improve the quality of care and efficiency in the use of resources. Descriptive observational study of a sample of 379 patients over 18 years old. The dependent variables were attendance (number of visits to their family doctor during the previous year), frequent attendance (10 or more visits to the family doctor in the last year), and persistent frequent attenders (10 or more visits to the family doctor in each of the last two years). Data were collected from medical records and by telephone interview. The mean attendance was 6.83 (95%CI: 6.13-7.53), frequent attendance reached 25.4% (95%CI: 21.4-29.6), and persistent frequent attenders, 1.6% (95%CI: 0.5-2.9). Frequent attendance was associated with sex, age, marital status, educational level, family structure, existence of chronic disease, use of anxiolytic and antidepressants, request for additional tests, and referrals to other specialists, proximity to the health center, and level of satisfaction with their family doctor. The low persistent frequent attenders found suggests that frequent attendance could be largely due to factors related to professional and organization. Studies are required to address the high level of consumption of psychotropic drugs, and improving professional skills in dealing with mental problems.

In New Zealand, Pacific health figures are traditionally presented for all Pacific ethnic groups combined. Use of EDs and urgent care clinics is high compared with Maori and non-Maori, non-Pacific (nMnP) use. By controlling for proximity to the hospital and socioeconomic status, we demonstrate greater variation between Pacific ethnic groups than between Pacific and nMnP, or between Maori and nMnP groups. We discuss the significance of subpopulation variation in use of urgent care services. © 2016 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

GRAMI: Frequent subgraph and pattern mining in a single large graph

KAUST Repository

Elseidy, M.

2014-01-01

Mining frequent subgraphs is an important operation on graphs; it is defined as finding all subgraphs that appear frequently in a database according to a given frequency threshold. Most existing work assumes a database of many small graphs, but modern applications, such as social networks, citation graphs, or proteinprotein interactions in bioinformatics, are modeled as a single large graph. In this paper we present GRAMI, a novel framework for frequent subgraph mining in a single large graph. GRAMI undertakes a novel approach that only finds the minimal set of instances to satisfy the frequency threshold and avoids the costly enumeration of all instances required by previous approaches. We accompany our approach with a heuristic and optimizations that significantly improve performance. Additionally, we present an extension of GRAMI that mines frequent patterns. Compared to subgraphs, patterns offer a more powerful version of matching that captures transitive interactions between graph nodes (like friend of a friend) which are very common in modern applications. Finally, we present CGRAMI, a version supporting structural and semantic constraints, and AGRAMI, an approximate version producing results with no false positives. Our experiments on real data demonstrate that our framework is up to 2 orders of magnitude faster and discovers more interesting patterns than existing approaches. 2014 VLDB Endowment.

We studied the immune response after starting antiretroviral treatment (ART) in 15,646 HIV-infected patients with or without tuberculosis (TB) at presentation in 3 ART programs in South Africa between 2003 and 2010. Patients presenting with TB had similar increases in CD4 cells compared with all other patients (adjusted difference 4.9 cells/µL per 6 months, 95% confidence interval: 0.2 to 9.7). Younger age, advanced clinical stage, female sex, and lower CD4 cell count at ART start were all associated with steeper CD4 slopes. In South Africa, HIV-infected patients presenting with TB experience immune recovery after starting ART that is no worse than in other patients.

Enhancement of allergic skin wheal responses in patients with atopic eczema/dermatitis syndrome by playing video games or by a frequently ringing mobile phone.

Kimata, H

2003-06-01

Playing video games causes physical and psychological stress, including increased heart rate and blood pressure and aggression-related feelings. Use of mobile phones is very popular in Japan, and frequent ringing is a common and intrusive part of Japanese life. Atopic eczema/dermatitis syndrome is often exacerbated by stress. Stress increases serum IgE levels, skews cytokine pattern towards Th2 type, enhances allergen-induced skin wheal responses, and triggers mast cell degranulation via substance P, vasoactive intestinal peptide and nerve growth factor. (1). In the video game study, normal subjects (n = 25), patients with allergic rhinitis (n = 25) or atopic eczema/dermatitis syndrome (n = 25) played a video game (STREET FIGHTER II) for 2 h. Before and after the study, allergen-induced wheal responses, plasma levels of substance P, vasoactive intestinal peptide and nerve growth factor, and in vitro production of total IgE, antihouse dust mite IgE and cytokines were measured. (2). In the mobile phone study, normal subjects (n = 27), patients with allergic rhinitis (n = 27) or atopic eczema/dermatitis syndrome (n = 27) were exposed to 30 incidences of ringing mobile phones during 30 min. Before and after the study, allergen-induced wheal responses, plasma levels of substance P, vasoactive intestinal peptide and nerve growth factor were measured. Playing video games had no effect on the normal subjects or the patients with allergic rhinitis. In contrast, playing video games significantly enhanced allergen-induced skin wheal responses and increased plasma levels of substance P, vasoactive intestinal peptide and nerve growth factors in the patients with atopic eczema/dermatitis syndrome. Moreover, playing video games enhanced in vitro production of total IgE and anti-house dust mite IgE with concomitant increased production of IL-4, IL-10 and IL-13 and decreased production of IFN-gamma and IL-12 in the patients with atopic eczema/dermatitis syndrome. However, exposure

Full Text Available Infections associated with medical procedures, or hospital-acquired infections (HAIs, occur in all hospitals worldwide. An integrated infection-control program with HAI surveillance as its cornerstone can reduce the incidence of HAIs and contribute to economic benefits. The aim of this paper was to report the prevalence and epidemiological features of HAI in hospitals in Vojvodina, Serbia. The study population examined herein was compromised of all of the patients present in the ward at least 48 hours before the day of surveillance. It also included patients that were scheduled for discharge or transfer, and those temporarily absent from the ward for examinations or diagnostic procedures. Data were collected using uniform questionnaires, created by the scientific board of the study. Data from paper questionnaires were entered into a specially created electronic database and analyzed using standard statistical methods. A total of 2 435 patients were included in the study. The frequency of patients with HAI was 6.6% (95% CI: 5.6%-7.6%, and the prevalence of infection was 7.1% (95% CI: 6.1%-8.1%. HAI prevalence was significantly different depending on the ward, ranging from 1.7% in the gynecology department to 18.1% in intensive care departments. The most common type of HAI was pneumonia, representing 20.9% of all reported HAIs. The second most frequently reported type of HAI was surgical site infection (19.8%, followed by urinary tract infection (17.4%, gastro-intestinal infection (14.5% and bloodstream infection (11.0%. The most commonly found microorganisms were Enterococcus spp. (14.5%, Klebsiella pneumoniae (14.5%, Acinetobacter spp. (13.7%, coagulase-negative Staphylococcus spp. (12.1%, Pseudomonas aeruginosa (10.5% and Clostridium difficile (7.3%. The most frequently used antibiotics in therapy were third generation cephalosporins to which most of the isolates showed resistance. Although the consumption of carbapenems in this sample was only

Agitated delirium is frequent following acute brain injury, but data are limited in patients with subarachnoid hemorrhage (SAH). We examined incidence, risk factors, and consequences of agitation in these patients in a single-center retrospective study. We identified all patients treated with antipsychotics or dexmedetomidine from a prospective observational cohort of patients with spontaneous SAH. Agitation was confirmed by chart review. Outcomes were assessed at 12 months using the modified Rankin Scale (mRS), Telephone Interview for Cognitive Status (TICS), and Lawton IADL (Instrumental Activities of Daily Living) scores. Independent predictors were identified using logistic regression. From 309 SAH patients admitted between January 2011 and December 2015, 52 (17 %) developed agitation, frequently in the first 72 h (50 %) and in patients with Hunt-Hess grades 3-4 (12 % of grades 1-2, 28 % of grades 3-4, 8 % of grade 5). There was also a significant association between agitation and a history of cocaine use or prior psychiatric diagnosis. Agitated patients were more likely to develop multiple hospital complications; and in half of these patients, complications were diagnosed within 24 h of agitation onset. Agitation was associated with IADL impairment at 12 months (Lawton >8; p = 0.03, OR 2.7, 95 % CI, 1.1-6.8) in non-comatose patients (Hunt-Hess 1-4), but not with functional outcome (mRS >3), cognitive impairment (TICS ≤30), or ICU/hospital length of stay after controlling for other predictors. Agitation occurs frequently after SAH, especially in non-comatose patients with higher clinical grades. It is associated with the development of multiple hospital complications and may have an independent impact on long-term outcomes.

Myasthenia gravis (MG) is an autoimmune disorder presenting with fluctuating, fatigable muscle weakness. Initial symptoms classically involve ocular and proximal limb muscles. Rarely, MG may onset with unusual features, so it can be misdiagnosed with other neuromuscular diseases. To describe unusual and atypical presentations of MG in a large cohort of patients, considering and discussing diagnostic difficulties and pitfalls. We report on 21 out of 508 MG patients, coming to our department in the last 27 years and presenting with atypical or unusual features. The diagnosis was achieved performing a careful clinical examination, a proper neurophysiological assessment, the neostigmine test, the AChR and MuSK antibodies assay and chest CT-scan. Patients with atypical/unusual MG onset were the 4.4% of all MG patients population. We describe seven different clinical categories: asymmetric distal upper limbs weakness, foot drop, isolated triceps brachii weakness and foot drop, post exertional axial weakness with dropped head, acute facial dyplegia, limb-girdle MG and MG with sudden lower limbs weakness and recurrent falls. Atypical and unusual presentations may increase the risk to misdiagnose or delay MG diagnosis. Isolated limb-girdle presentation is the most frequent atypical form in our series.

Although there are well-established risk factors for the diagnosis of bladder cancer, there is no consensus regarding risk factors for presentation of advanced or metastatic disease at diagnosis. The objective of this study was to identify the demographic and clinical factors associated with metastasis at diagnosis in patients with bladder urothelial carcinoma. Patients diagnosed with bladder urothelial carcinoma from 2004 to 2010 were identified in the Surveillance, Epidemiology, and End Results (SEER) database (n = 108,417). The primary outcome was metastatic disease at the time of diagnosis. Demographic and socioeconomic variables were analyzed, and multivariable logistic regression models were performed to generate odds ratios (OR) for factors associated with metastasis at diagnosis. Of patients with bladder cancer, 3018 (2.8%) had metastasis at diagnosis and 105,399 (97.2%) had nonmetastatic disease. Patients with metastatic disease at diagnosis were more frequently female (29.6% vs. 23.6%, P vs. 5.0%, P unmarried (44.1% vs. 32.5%, P vs. male, OR 1.21), black race (vs. white, OR 1.71), unmarried (vs. married, OR 1.46), unemployed (OR 1.02), and foreign-born status (OR 1.01). Female gender, black race, unmarried, unemployed, and foreign-born status are independently associated with metastasis at diagnosis for bladder urothelial carcinoma. All clinicians should be aware of these potential health care disparities in order to involve social services and other support mechanisms in efforts to improve early care.

Getting patients to say yes to recommended treatment requires the dedication of each team member. It demands a commitment to educating patients and motivating them to turn their dental needs into dental wants, as well as providing financial options to make treatment affordable. When the dental team takes the time to nurture the case presentation process, the results can be dramatic. Patients embrace treatment and the practice provides it. It is nothing short of a win-win scenario.

Sporotrichosis is a human and animal disease caused by species of the Sporothrix schenckii complex. It is classically acquired through traumatic inoculation of fungal elements. Most frequently, sporotrichosis presents as a fixed cutaneous or as a lymphocutaneous form. A much smaller number of cases occur as cutaneous disseminated and disseminated forms. These cases require immediate diagnosis and management to reduce morbidity and mortality. We present the case of a 34-year-old male patient in whom the first presentation of HIV infection was a rapidly progressive sporotrichosis with multiple cutaneous lesions, a high fungal burden in tissues, and pulmonary involvement. He had an extremely low CD4 cell count (06/mm 3 ). Treatment with amphotericin B deoxycholate led to complete clinical resolution. Sporotrichosis remains a neglected opportunistic infection among HIV-infected patients in Rio de Janeiro state, Brazil, and awareness of this potentially fatal infection is of utmost importance if treatment is not to be delayed and if potentially devastating complications are to be avoided.

Frequent visitors at the psychiatric emergency room - A literature review.

Schmidt, Manuela

2018-03-01

Frequent visitors at the psychiatric emergency room (PER) constitute a small subgroup of patients, yet they are responsible for a disproportionate number of visits and thus claim considerable resources. Their needs are often left unmet and their repetitive visits reflect their dissatisfaction as well as that of PERs' staff. Motivated by these dilemmas, this study systematically reviews the literature about frequent visitors at PER and seeks to answer two questions: What characterizes frequent visitors at PER in the literature? and What characterizes PER in the literature? Based on 29 studies, this paper offers answers to the two questions based on a strength weakness opportunities and threats (SWOT) analysis. The results of the review and subsequent analysis of the literature revealed the multiplicity and complexity of frequent visitors' characteristics and how they appear to converge. Commonalities were more difficult to identify in PER characteristics. In some cases, this happened because the characteristics were poorly described or were context specific. As a result, it was not easy to compare the studies on PER. Based on SWOT and the findings of the analysis, the paper proposes new venues of research and suggests how the field of mental health might develop by taking into account its opportunities and threats.

Full Text Available (1 Background: Celiac disease (CD patients can be affected by mouth and tooth disorders, which are influenced by their gluten-free diet. The aim of our research was to evaluate the pathological conditions of the stomatognathic system observed in celiac patients on a gluten-free diet. (2 Methods: we consecutively recruited celiac patients on a gluten-free diet at our celiac center, as well as healthy volunteers. Two dentists examined all patients/controls and checked them for any mouth disorder. (3 Results: Forty-nine patients affected by celiac disease (age at test 31.8 ± 11.58, time on GFD 8.73 ± 7.7 and 51 healthy volunteers (age at test 30.5 ± 8.7 were included. Recurrent aphthous stomatitis was reported in 26 patients (53.0% and in 13 (25.5% controls (p = 0.005. Dental enamel disorders were reported in 7 patients (14.3% and in 0 controls (p = 0.002, with none having geographic tongue. We found non-specific tooth wear, characterized by loss of the mineralized tissue of the teeth, in 9 patients (18.3% and in 3 (5.9% controls (p = 0.05. (4 Conclusion: Recurrent aphthous stomatitis and enamel hypoplasia are “risk indicators” that may suggest that an individual has CD. We detected a high prevalence of non-specific tooth wear that can be caused by several factors such as malocclusion, sleep bruxism, parafunctional activity, and age.

Addison's disease or primary adrenal insufficiency is a rare disease in children. The signs and symptoms at diagnosis are frequently non-specific and insidious. Since adrenal crisis represents an emergency, it is important to be aware and to have a high degree of suspicion of the disorder in order to achieve an early diagnosis and treatment. We present a retrospective study describing the epidemiological, clinical and etiological data at diagnosis of five patients with Addison's disease followed up in our hospital. Dehydration, hyponatremia and skin hyperpigmentation were the most prevalent signs and symptoms at onset of the disease. The patients had low serum cortisol levels and positive adrenal antibodies. One patient with negative antibodies presented with a polyglandular syndrome. Copyright © 2012 Asociación Española de Pediatría. Published by Elsevier España, S.L. All rights reserved.

Full Text Available Introduction: Case management is an effective, short-term means to reduce emergency department (ED visits in frequent users of the ED. This study sought to determine the effectiveness of case management on frequent ED users, in terms of reducing ED and hospital length of stay (LOS, accrued costs, and utilization of diagnostic tests. Methods: The study consisted of a retrospective chart review of ED and inpatient visits in our hospital’s ED case management program, comparing patient visits made in the one year prior to enrollment in the program, to the visits made in the one year after enrollment in the program. We examined the LOS, use of diagnostic testing, and monetary charges incurred by these patients one year prior and one year after enrollment into case management. Results: The study consisted of 158 patients in case management. Comparing the one year prior to enrollment to the one year after enrollment, ED visits decreased by 49%, inpatient admissions decreased by 39%, the use of computed tomography imaging decreased 41%, the use of ultrasound imaging decreased 52%, and the use of radiographs decreased 38%. LOS in the ED and for inpatient admissions decreased by 39%, reducing total LOS for these patients by 178 days. ED and hospital charges incurred by these patients decreased by 5.8 million dollars, a 41% reduction. All differences were statistically significant. Conclusion: Case management for frequent users of the ED is an effective method to reduce patient visits, the use of diagnostic testing, length of stay, and cost within our institution.

Autoimmune encephalitis with anti-N-methyl-d-aspartate receptor autoantibodies (NMDA-R-Abs) is a recently described disease affecting adult and pediatric patients. Symptoms of the disease are now perfectly described in the adult population but the clinical presentation is less known in young children. The aim of the present study was to describe the clinical presentation and the specificities of symptoms presented by young children with NMDA-R-Abs encephalitis to improve diagnosis of this disease, and to compare these to a series of previously published female adult patients. Fifty cases of children younger than twelve years of age diagnosed with NMDA-R-Abs encephalitis between January 1, 2007 and December 31, 2016 (27 females and 23 males) were retrospectively studied. The first neurological symptoms observed in young children with NMDA-R-Abs encephalitis were characterized by seizure (72%), especially focal seizure (42%), within a median of 15 days before other encephalitis symptoms; other patients mostly had behavioral disorders (26%). The seizures were frequently difficult to diagnose because of the transient unilateral dystonic or tonic posturing presentation or sudden unilateral pain in the absence of clonic movements. A post-ictal motor deficit was also frequently observed. This clinical presentation is different from that observed in adult females with NMDA-R-Abs encephalitis who initially present mainly psychiatric disorders (67%) or cognitive impairment (19%), and less frequently seizures (14%). The diagnosis of NMDA-R-Abs encephalitis should be systematically considered in young children of both sexes who present neurological symptoms suggesting recent seizures (focal or generalized) without obvious other etiology.

Sialorrhoea: How to Manage a Frequent Complication of Motor Neuron Disease

Directory of Open Access Journals (Sweden)

Andrea Pellegrini

Full Text Available Sialorrhoea, the unintentional loss of saliva through the mouth, is the frequent complication of neurological disorders affecting strength or coordination of oropharyngeal muscles, such as motor neuron disease/amyotrophic lateral sclerosis (MND/ALS or Parkinson’s disease. Sialorrhoea might affect up to 42% of ALS patients, with almost half of them having poorly managed symptoms. Sialorrhoea can impair patients’ social life, while dermatological complications, such as skin rashes, may arise due to constant exposure to moisture. Moreover, the excess mouth-retained saliva in ALS patients may lead to serious complications, such as choking, which causes anxiety, and aspiration with the consequent pneumonia. The inclusion of a sialorrhoea-related item in the ALS functional rating scale testifies both the incidence and importance of sialorrhoea during the ALS clinical course. Because of the progressive nature of ALS, presence and severity of sialorrhoea should be assessed at every visit and, when present, active treatment pursued. Available treatments include behavioural therapy, i.e. techniques to enhance periodic swallowing of saliva, systemic or local anticholinergic medications, botulinum toxin injection, electron beam irradiation, and surgical techniques. This review paper briefly describes the available options with related side-effects and current guideline recommendations for managing sialorrhoea in ALS patients.

Recently, CLPB deficiency has been shown to cause a genetic syndrome with cataracts, neutropenia, and 3-methylglutaconic aciduria. Surprisingly, the neurological presentation ranges from completely unaffected to patients with virtual absence of development. Muscular hypo- and hypertonia, movement disorder and progressive brain atrophy are frequently reported. We present the foetal, peri- and neonatal features of 31 patients, of which five are previously unreported, using a newly developed clinical severity scoring system rating the clinical, metabolic, imaging and other findings weighted by the age of onset. Our data are illustrated by foetal and neonatal videos. The patients were classified as having a mild (n = 4), moderate (n = 13) or severe (n = 14) disease phenotype. The most striking feature of the severe subtype was the neonatal absence of voluntary movements in combination with ventilator dependency and hyperexcitability. The foetal and neonatal presentation mirrored the course of disease with respect to survival (current median age 17.5 years in the mild group, median age of death 35 days in the severe group), severity and age of onset of all findings evaluated. CLPB deficiency should be considered in neonates with absence of voluntary movements, respiratory insufficiency and swallowing problems, especially if associated with 3-methylglutaconic aciduria, neutropenia and cataracts. Being an important differential diagnosis of hyperekplexia (exaggerated startle responses), we advise performing urinary organic acid analysis, blood cell counts and ophthalmological examination in these patients. The neonatal presentation of CLPB deficiency predicts the course of disease in later life, which is extremely important for counselling.

Ocular manifestations of sarcoidosis in children are the second most common occurrence after hilar adenopathy and pulmonary abnormalities. We present the case history of a 14-year-old black boy who presented with redness of the left eye, blurred vision, and decreased visual acuity. He was subsequently diagnosed as having sarcoidosis. All patients with uveitis or ocular findings suggestive of sarcoidosis should have a through medical examination and a chest x-ray. Those suspected of or proven to have sarcoidosis should have a complete ophthalmological examination. Sarcoidosis in children appears to be more frequent than previously estimated.

Past, Present, and Future Old Growth in Frequent-fire Conifer Forests of the Western United States

Full Text Available Old growth in the frequent-fire conifer forests of the western United States, such as those containing ponderosa pine (Pinus ponderosa, Jeffrey pine (P. jeffreyi, giant sequoia (Sequioa giganteum and other species, has undergone major changes since Euro-American settlement. Understanding past changes and anticipating future changes under different potential management scenarios are fundamental to developing ecologically based fuel reduction or ecological restoration treatments. Some of the many changes that have occurred in these forests include shifts from historically frequent surface fire to no fire or to stand-replacing fire regimes, increases in tree density, increased abundance of fire-intolerant trees, decreases in understory productivity, hydrological alterations, and accelerated mortality of old trees. Although these changes are widespread, the magnitude and causes of changes may vary within and among landscapes. Agents of change, such as fire exclusion or livestock grazing, likely interacted and had multiple effects. For example, historical ranching operations may have altered both fire regimes and understory vegetation, and facilitated institutional fire exclusion through fragmentation and settlement. Evidence exists for large variation in presettlement characteristics and current condition of old growth across this broad forest region, although there are many examples of striking similarities on widely distant landscapes. Exotic species, climate change, unnatural stand-replacing wildfires, and other factors will likely continue to degrade or eradicate old growth in many areas. As a policy of fire exclusion is proving to be unsustainable, mechanical tree thinning, prescribed fire, or wildland fire use will likely be key options for forestalling continued eradication of old growth by severe crown fires. For many practical and societal reasons, the wildland-urban interface may afford some of the most immediate opportunities for re

Reduced food intake is a frequent problem at a hospital setting, being a cause and/or consequence of malnutrition. Food presentation can affect food intake and induce nutritional benefit. To investigate the effect of improved meal presentation supported by gastronomy expertise on the food intake in adults hospitalized in internal medicine departments. Controlled before and after study. Two hundred and six newly hospitalized patients in internal medicine departments were included and divided in two groups, a) control: receiving the standard lunch from the hospital and b) experimental: receiving a lunch improved in terms of presentation by the advices received by the Institut Paul Bocuse, Ecully, Lyon, France together with the hospital kitchen of the Beilinson Hospital, without change in the composition of the meal. The amount of food left at the participants' plates was estimated using the Digital Imaging Method, which consisted in photographing the plates immediately to previous tray collection by the researcher. In addition, the nutritionDay questionnaire was used to measure other variables concerned to their food intake during hospitalization. Charlson Comorbidity Index was calculated. There was no significant difference between the groups regarding demography or Charlson Comorbidity Index. Patients who received the meal with the improved presentation showed significantly higher food intake than those who received the standard meal, despite reported loss in appetite. Participants from the experimental group left on their plate less starch (0.19 ± 0.30 vs. 0.52 + 0.41) (p  0.05). Both of the groups were asked how hungry they were before the meal and no significance was shown. More participants from the experimental group reported their meal to be tasty in comparison to those in the control group (49.5% vs. 33.7% p < 0.005). Length of stay was not different but readmission rate decreased significantly in the study group (p < 0.02) from 31.2% to 13

In cross-sectional studies, psychological distress has been associated with frequent health care utilization. However, there is a need for prospective studies to confirm these findings. This cohort study evaluated whether psychological distress predicted frequent attendance in family practice.......16 [0.99-1.36] for SCL and OR 1.31 [1.05-1.65] for Whiteley). Psychological distress involved an increased risk of future frequent attendance among adult patients consulting family practice in the daytime about an illness........ In 1990, 185 consecutive adults who consulted their primary care physician (PCP) about an illness were rated on two psychometric scales (Hopkins Symptom Check List [SCL-8] and Whiteley-7), and their annual number of face-to-face contacts with a family practice was followed until 1996.

Breast cancer patients are presenting at advanced stages for oncological treatment in Nigeria and World Health Organization predicted developing countries' breast cancer incidence and mortality to increase by year 2020. Prospective observational hospital based study that enrolled breast cancer patients from catchment area of an oncology service hospital in Nigeria between 2007 and 2013. Patients' demographics, breast cancer burden and health care giver presentation variables were analysed for causal factors of seeking medical help and what determines commencement of effective oncological treatment. Forty-six patients were enrolled, 19.6% of them presented primarily to oncologist while 80.4% presented secondarily for oncological treatment. There is a significant difference in presentation time for oncological treatment (t = -3.56, df = 42.90, p = 0.001) between primary (M =11.56 ± 5.21 weeks) and secondary presentation (M= 52.56 ± 10.27weeks). Tumor burden of those that presented secondarily were significantly more advanced (U = 78.5, p = 0.011) and, univariate analysis reveals that: patients' matrimonial setting, breast cancer awareness and mode of discovery of breast symptoms are patient related factors that determines their choice of health care providers and, determinant of effective oncological treatment is patient first contact health care provider. Patients' bio-characteristics that determine their choice of health care provider should be incorporated into community breast cancer sensitization drives. Additionally, there is a need for a government agency assign the task of accrediting and defining scope of enterprise of health care institutions and their health care providers in our pluralist health system.

Pseudohypertension-Like Presentation: An Exceptionally Rare Presentation in an Athletic Female Patient with Morphea

Directory of Open Access Journals (Sweden)

Ahmed Al-Imam

2016-01-01

Full Text Available Introduction. Pseudohypertension is a condition which mainly occurs due to thickening-calcification of tunica intima of the arterial wall, leading to a faulty measurement of the intra-arterial blood pressure. To the best of our knowledge, this is the first case report in literature, of a pseudohypertension-like presentation in association with Morphea en plaque. Case Presentation. This is a rare presentation of a young athletic female and a professional tennis player, with pseudohypertension-like presentation. The patient had a traumatic injury to the right elbow joint; the injury occurred during a professional tennis match. The injury was managed by immobilization, physiotherapy, and Low-Level Laser Therapy. Soon after that, the patient had a circumscribed sclerotic ivory plaque affecting the skin of the right cubital fossa. The histopathology analysis, together with the serological-hematological tests and the clinical picture, along with positive Osler’s signs, leads to the conclusive diagnosis of Morphea en plaque. The peculiar anatomic localization of the plaque anterior to the brachial artery leads to faulty blood pressure measurement as recorded by mercurial sphygmomanometer. Conclusion. This unique presentation of Morphea en plaque carries an important message in relation to the basic medical practice and in relation to the accurate measurement of the vital signs.

Moyamoya is a rare cerebrovascular disease characterized by the progressive occlusion of the intracranial carotid artery. Thyroid autoantibodies have been found to be associated with the disease, but their clinical significance has never been studied. The objective of this study was to investigate the relationship between thyroid autoantibodies and the clinical presentation of moyamoya. This is a prospective study including 37 patients with moyamoya disease (MMD) or unilateral moyamoya (uMM). Thyroid function and thyroid autoantibodies (e.g., antithyroperoxidase and antithyroglobulin) were investigated. We studied the effect of gender, age, type of moyamoya (uMM versus MMD), and thyroid autoantibodies on the clinical presentation, dichotomized into aggressive (hemorrhage, major stroke, or frequent transient ischemic attack [TIA]) and nonaggressive presentation (headache, rare TIAs, and incidental diagnosis) according to the criteria of the Research Committee on Spontaneous Occlusion of the Circle of Willis. Of the 37 patients included in the study, the autoantibodies were elevated in 9 (24.3%). An aggressive presentation occurred in 21 patients (hemorrhage in 11, major stroke in 9, frequent TIAs in 1). The autoantibodies were elevated in 8 of the 21 patients (38.09%) with an aggressive presentation and in 1 of those presenting with minor symptoms (6.2%). The presence of elevated autoantibodies was the only variable associated with an aggressive presentation in the multivariate logistic analysis (P = .048). When the serum concentration of the thyroid autoantibodies is increased, the patients have a higher risk of an aggressive presentation. Our results support the hypothesis that activation of immune-mediated processes affects the moyamoya physiopathology. Copyright © 2018 National Stroke Association. Published by Elsevier Inc.

Enumerating all maximal frequent subtrees in collections of phylogenetic trees.

Science.gov (United States)

Deepak, Akshay; Fernández-Baca, David

2014-01-01

A common problem in phylogenetic analysis is to identify frequent patterns in a collection of phylogenetic trees. The goal is, roughly, to find a subset of the species (taxa) on which all or some significant subset of the trees agree. One popular method to do so is through maximum agreement subtrees (MASTs). MASTs are also used, among other things, as a metric for comparing phylogenetic trees, computing congruence indices and to identify horizontal gene transfer events. We give algorithms and experimental results for two approaches to identify common patterns in a collection of phylogenetic trees, one based on agreement subtrees, called maximal agreement subtrees, the other on frequent subtrees, called maximal frequent subtrees. These approaches can return subtrees on larger sets of taxa than MASTs, and can reveal new common phylogenetic relationships not present in either MASTs or the majority rule tree (a popular consensus method). Our current implementation is available on the web at https://code.google.com/p/mfst-miner/. Our computational results confirm that maximal agreement subtrees and all maximal frequent subtrees can reveal a more complete phylogenetic picture of the common patterns in collections of phylogenetic trees than maximum agreement subtrees; they are also often more resolved than the majority rule tree. Further, our experiments show that enumerating maximal frequent subtrees is considerably more practical than enumerating ordinary (not necessarily maximal) frequent subtrees.

Mining top-k frequent closed itemsets in data streams using sliding window

International Nuclear Information System (INIS)

Rehman, Z.; Shahbaz, M.

2013-01-01

Frequent itemset mining has become a popular research area in data mining community since the last few years. T here are two main technical hitches while finding frequent itemsets. First, to provide an appropriate minimum support value to start and user need to tune this minimum support value by running the algorithm again and again. Secondly, generated frequent itemsets are mostly numerous and as a result a number of association rules generated are also very large in numbers. Applications dealing with streaming environment need to process the data received at high rate, therefore, finding frequent itemsets in data streams becomes complex. In this paper, we present an algorithm to mine top-k frequent closed itemsets using sliding window approach from streaming data. We developed a single-pass algorithm to find frequent closed itemsets of length between user's defined minimum and maximum- length. To improve the performance of algorithm and to avoid rescanning of data, we have transformed data into bitmap based tree data structure. (author)

The influence of the presenting electrocardiographic (ECG) findings on the treatment and outcomes of patients with non-ST-segment elevation myocardial infarction (NSTEMI) has not been studied in contemporary practice. We analyzed the clinical characteristics, in-hospital management, and in-hospital outcomes of patients with NSTEMI in the Acute Coronary Treatment and Intervention Outcomes Network Registry-Get With The Guidelines (ACTION Registry-GWTG) according to the presenting ECG findings. A total of 175,556 patients from 485 sites from January 2007 to September 2011 were stratified by the ECG findings on presentation: ST depression (n = 40,146, 22.9%), T-wave inversions (n = 24,627, 14%), transient ST-segment elevation (n = 5,050, 2.9%), and no ischemic changes (n = 105,733, 60.2%). Patients presenting with ST-segment depression were the oldest and had the greatest prevalence of major cardiac risk factors. Coronary angiography was performed most frequently in the transient ST-segment elevation group, followed by the T-wave inversion, ST-segment depression, and no ischemic changes groups. The angiogram revealed that patients with ST-segment depression had more left main, proximal left anterior descending, and 3-vessel coronary artery disease and underwent coronary artery bypass grafting most often. In contrast, patients with transient ST-segment elevation had 1-vessel CAD and underwent percutaneous coronary intervention the most. The unadjusted mortality was highest in the ST-segment depression group, followed by the no ischemic changes, transient ST-segment elevation, and T-wave inversion group. Adjusted mortality using the ACTION Registry-GWTG in-hospital mortality model with the no ischemic changes group as the reference showed that in-hospital mortality was similar in the transient ST-segment elevation (odds ratio 1.15, 95% confidence interval 0.97 to 1.37; p = 0.10), higher in the ST-segment depression group (odds ratio 1.46, 95% confidence interval 1

Patients with sickle cell anemia (SCA) are frequently transfused with red blood cells (RBC). Recently we reported that the calculated risk of RBC alloimmunization per transfussed unit in Brazilian patients with SCA is 1.15%. We describe a delayed hemolytic transfusion reaction (DHTR) presenting as a painful crisis in a patient with SCA. A 35-year-old Brazilian female with homozygous SCA was admitted for a program of partial exchange transfusion prior to cholecystectomy. Her blood group was O RhD positive and no atypical RBC alloantibody was detected using the indirect antiglobulin technique. Pre-transfusional hemoglobin (Hb) was 8.7 g/dL and isovolumic partial exchange transfusion was performed using 4 units of ABO compatible packed RBC. Five days after the last transfusion she developed generalized joint pain and fever of 39 degrees C. Her Hb level dropped from 12.0 g/dL to 9.3 g/dL and the unconjugated bilirrubin level rose to 27 mmol/L. She was jaundiced and had hemoglobinuria. Hemoglobin electrophoresis showed 48.7% HbS, 46.6% HbA1, 2.7% HbA2, and 2.0% HbF. The patient's extended RBC phenotype was CDe, K-k+, Kp(a-b+), Fy(a-b-), M+N+s+, Le(a+b-), Di(a-). An RBC alloantibody with specificity to the Rh system (anti-c, titer 1:16.384) was identified by the indirect antiglobulin test. The Rh phenotype of the RBC used in the last packed RBC transfusion was CcDEe. The patient was discharged, asymptomatic, 7 days after admission.

Venous thromboembolism (VTE) represents a serious complication after oncologic surgery. Recent studies have shown that the risk of VTE persists several weeks after surgery. This study assesses the form of presentation and time course of VTE after abdominal and pelvic cancer surgery. Prospective, multicenter, observational study that analyzes data from an international registry (RIETE) that includes consecutive patients with symptomatic VTE. Our study assesses the form and time of presentation of postoperative VTE, as well as main outcomes, in patients operated for abdominopelvic cancer 8 weeks prior to VTE diagnosis. Variables related to the presentation of VTE after hospital discharge are identified. Out of the 766 analyzed patients with VTE, 395 (52%) presented pulmonary embolism (PE). Most VTE cases (84%) were detected after the first postoperative week, and 38% after one month. Among patients with VTE in the first postoperative week, 70% presented PE. VTE presented after hospital discharge in 54% of cases. Colorectal, urologic, and gynecologic tumors, the use of radiotherapy, and blood hemoglobin levels were independently associated with VTE diagnosis after hospital discharge. Complications (thrombosis recurrence, bleeding, and death) occurred in 34% of patients with VTE detected before hospital discharge, compared to 24% in VTE after hospital discharge (P<0.01). VTE occurs after hospital discharge in most patients, particularly in those operated for colorectal, urologic, and gynecologic cancer. Pulmonary embolism is more frequent in patients who develop early VTE, who also have worse prognosis. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

Neonatal adrenal hematoma is a rare condition, most frequently caused by trauma. We report three cases of adrenal hematoma admitted to the Neonatology and Neonatal Intensive Care Unit in the A. Harouchi Children's Hospital, the Ibn Rushd University Hospital in Casablanca, Morocco, over a 2-year period from January 2011 to December 2012. The average age of these patients was 5 days. The clinical presentations were diverse; the most common manifestations were intense jaundice in one case, acute adrenal insufficiency in one case, and severe anemia in the other case. Abdominal ultrasonography was used to confirm the diagnosis and monitor adrenal hemorrhage in all the patients. Analysis of clinical, laboratory, and ultrasonography data showed a favorable prognosis in all the patients. Based on these observations, we discuss the risk factors, clinical presentations, progression and management of neonatal adrenal hemorrhage. Copyright © 2014. Published by Elsevier SAS.

Néstor Pacenza

2012-01-01

Full Text Available The aim of the study was to establish the characteristics of presentation of 94 patients with Kinelfelter's syndrome (KS referred to the endocrinologist at different ages. The diagnosis of KS was more frequent in the age group between 11 and 20 years (46.8%. Most of the patients (83.7% showed the classic 47,XXY karyotype and 7.1% showed a 47,XXY/46,XY mosaicism. Half of the patients younger than 18 years presented mild neurodevelopmental disorders. The most frequent clinical findings were cryptorchidism in prepubertal patients, and small testes, cryptorchidism, and gynecomastia in pubertal patients. FSH, LH, AMH, and inhibin B levels were normal in prepubertal patients and became abnormal from midpuberty. Most adults were referred for small testes, infertility, and gynecomastia; 43.6% had sexual dysfunction. Testosterone levels were low in 45%. Mean stature was above the 50th percentile, and 62.5% had BMI ≥25.0 kg/m2. In conclusion, the diagnosis of Klinefelter syndrome seems to be made earlier nowadays probably because pediatricians are more aware that boys and adolescents with neuro-developmental disorders and cryptorchidism are at increased risk. The increasing use of prenatal diagnosis has also decreased the mean age at diagnosis and allowed to get insight into the evolution of previously undiagnosed cases, which probably represent the mildest forms. In adults average height and weight are slightly higher than those in the normal population. Bone mineral density is mildly affected, more at the spine than at the femoral neck level, in less than half of cases.

Dialysis guidelines in Japan recommend more frequent measurement of mineral metabolism markers than the Kidney Disease: Improving Global Outcomes guidelines. However, the extent to which frequent marker measurement contributes to achievement of target ranges and to therapy adjustment is unknown. This multicenter cohort study involved 3276 hemodialysis patients with secondary hyperparathyroidism. Data on laboratory measurements and drug prescriptions were collected every 3 months. Main exposures were frequencies of measuring serum calcium and phosphorus [weekly/biweekly/monthly (reference)] and serum parathyroid hormone (PTH) [monthly/bimonthly/trimonthly (reference)] levels. Outcomes were achievement of guideline-specified ranges of mineral metabolism markers when serum levels were over, and maintenance of ranges when levels were already within, respective specified ranges, use of intravenous vitamin D receptor activator (VDRA) and initiation of cinacalcet use. Associations were examined via generalized estimating equations. When serum marker levels exceeded the target range, weekly measurement of calcium and phosphorus was positively associated with achievement of the guideline-specified calcium range [adjusted odds ratio (AOR): 1.57, 95% confidence interval (CI) 1.09-2.26] but not phosphorus range (AOR: 0.99, 95% CI 0.74-1.33). Monthly measurement of PTH was positively associated with achievement of the guideline-specified PTH range (AOR: 1.14, 95% CI 1.01-1.27). When serum marker levels were within the guideline-specified range, increased frequency of measurements was not associated with in-range maintenance of marker levels for any of the three mineral markers assessed. Regarding treatment regimen, relatively frequent measurement of serum calcium and phosphorus was positively associated with cinacalcet initiation and relatively frequent measurement of serum PTH with cinacalcet initiation and intravenous VDRA use. Our results suggest that increasing frequency of

Full Text Available BACKGROUND: Patent ductus arteriosus (PDA at childhood is one of the five major and frequent congenital abnormalities, but it can be rarely seen in adults. Pulmonary hypertension (PHTN and other presentations such as heart failure and edema are the identified complications of longstanding PDA, but adult case with no permanent heart symptoms and PHTN was rare. We reported a rare case of with an obvious PDA and normal pulmonary pressure. CASE REPORT: A 61-year-old woman presented with dyspnea (New York Heart Association class 2, chest pain, and lower limb edema. Echocardiogram showed; normal left ventricular chamber size and function, normal size of both atria. Furthermore, an obvious PDA (diameter = 6-7 mm connecting the aortic arch to the pulmonary artery was reported in echocardiography. No lung congestion and evidence for PHTN was reported by computed tomographic angiography [Pulmonary capillary wedge pressure (PCWP = 30 mmHg]. The patient was treated with antihypertensive drugs and after 1 and 3 months follow-up, edema and other symptoms were resolved. CONCLUSION: Finally, we conclude that PDA in adulthood can present with nonspecific cardiovascular symptoms, and it seems that PHTN is not a fixed echocardiographic finding in these patients.   Keywords: Adults, Edema, Patent Ductus Arteriosus eri, Pulmonary Hypertension  Normal 0 false false false EN-US X-NONE AR-SA

Full Text Available The urgency of the problem of frequently ill children is associated with a significant number of patients who can be assigned to this category. Objective: to present the nosological and etiological structure of diseases in frequently ill children depending on age.Subjects and methods. 243 children aged 1 to 17 years with recurrent respiratory infections were followed up. The children were examined using routine clinical, laboratory, and instrumental examinations. The etiological diagnosisincluded bacteriological examination of the upperrespiratory tract microflora; determination of IgM and IgG antibodies against Chlamydophila pneumoniae, Mycoplasma pneumoniae, Epstein–Barr virus(EBV, and cytomegalovirus(CMV in blood by enzyme immunoassay and that of Chlamydia and Mycoplasma DNA in pharyngealswabs and that of CMV, EBV and human herpesvirustype 6 DNA in blood by polymerase chain reaction.Results. Recurrentrespiratory diseases were found to be associated with herpesvirusinfection in 75% of the children aged 1 to 6 years, with Streptococcus, Mycoplasma, and Chlamydia infections in 16, 10, and 4% of those aged 3 to 6 years, respectively, and to be accompanied by abnormal lymphoid tissue proliferation in 84% of the children aged 3 to 6 years, with the abundant growth of bacterial opportunistic pathogensin one half of the patients. Despite the continuing importance of infectious agents(herpesviruses and streptococci in 29 and 20%, respectively, the chronically ill school-aged children displayed a high incidence of somatic diseases: chronic tonsillitis (43% and chronic sinusitis (14% in children aged older than 12 years and allergic rhinitis (23% in those aged 7 to 17 years. The symptoms of autonomic vascular dystonia were observed in 21% of the patients; cardiac arrhythmias were diagnosed in 14%.

The refeeding syndrome is a life-threatening complication that can occur after initiation of a nutrition therapy in malnourished patients. If the risk factors and pathophysiology are known, the refeeding syndrome can effectively be prevented and treated, if recognized early. A slow increase of food intake and the close monitoring of serum electrolyte levels play an important role. Because the refeeding syndrome is not well known and the symptoms may vary extremely, this complication is poorly recognized, especially against the background of geriatric multimorbidity. This overview is intended to increase the awareness of the refeeding syndrome in the risk group of geriatric patients.

Structured Abstract Objective This study sought to measure the incidence of perioperative beta-blocker non-compliance by patients who were prescribed chronic beta blocker therapy and presented for surgery from home. The effect of patient non-compliance on day of surgery presenting heart rate was also examined. Design Prospective observational study with outcome data obtained from review of the medical record. Setting The preoperative clinic and operating rooms of a Veterans Administration hospital. Participants Patients on chronic beta blocker therapy who presented from home for surgery. Interventions None. Measurements and Main Results Demographic and comorbidity data as well as data on self-reported compliance to beta-blocker therapy, initial day of surgery vital signs, and recent ambulatory vital signs were collected. Ten out of fifty subjects (20%; 95% CI = 9-31%) reported not taking their day of surgery beta-blocker. These self-reported non-adherers demonstrated a higher presenting heart rate on the day of surgery vs. adherent subjects (median of 78 beats per minute vs. 65 beats per minute, p=0.02 by Wilcoxon Rank-Sum Test). The difference-in-difference between baseline primary care and day of surgery heart rate was also statistically significant between compliant and non-compliant subjects (-7 beats per minute vs. +12.5 beats per minute, p<0.00001). Conclusions Patient self-report and physiologic data documented failure to take beta-blockers and possible beta-blocker withdrawal in 20% of patients who presented for surgery from home. If these findings are confirmed in larger studies, improved patient understanding of and compliance with medication instructions during preoperative visits should be a focus of future quality improvement initiatives.

Objective: To document the clinical presentation and epidemiology of various types of acute leukemia with their respective referral source at a tertiary level centre in Peshawar. Study Design: An observational study. Place and Duration of Study: Department of Pathology, Hayatabad Medical Complex (HMC), Peshawar, from January 2011 to May 2012. Methodology: A total of 618 bone marrow biopsy reports were reviewed. All biopsy reports labeled as acute leukemia were reviewed for age, gender, address, referring unit, diagnosis on bone marrow examination, presenting complaints, duration of illness and findings of clinical examination. Results: Ninety-two patients were diagnosed as suffering from acute leukemias (15%). ALL was most prevalent (46%), followed by AML (38%) and undifferentiated acute leukemia (16%). Males were affected more compared to females (60% vs. 40%). ALL and AML were predominant in pediatric (64%) and adults (77%) patients respectively. Patients from Afghanistan accounted for 33% of all cases followed by Peshawar (14%). Fever (77%), pallor (33%) and bleeding disorders (23%) were the main presenting complaints. Enlargement of liver, spleen and lymph nodes together was associated with ALL compared with AML (p = 0.004). Conclusion: ALL-L1 and AML-M4 were the most common sub-types. Fever, pallor and bleeding disorders were the main presenting complaints. Enlargement of liver, spleen and lymph nodes was more frequently associated with ALL compared to AML. (author)

Criteria for alcohol use disorders (AUD) in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) were intended to result in a similar prevalence of AUD as DSM-IV. We evaluated the prevalence of AUD using DSM-5 and DSM-IV criteria, and compared characteristics of patients who met criteria for: neither DSM-5 nor DSM-IV AUD, DSM-5 alone, DSM-IV alone, or both, among Veterans Administration (VA) outpatients in the Considering Healthier drinking Options In primary CarE (CHOICE) trial. VA primary care patients who reported frequent heavy drinking and enrolled in the CHOICE trial were interviewed at baseline using the DSM-IV Mini International Neuropsychiatric Interview for AUD, as well as questions about socio-demographics, mental health, alcohol craving, and substance use. We compared characteristics across 4 mutually exclusive groups based on DSM-5 and DSM-IV criteria. Of 304 participants, 13.8% met criteria for neither DSM-5 nor DSM-IV AUD; 12.8% met criteria for DSM-5 alone, and 73.0% met criteria for both DSM-IV and DSM-5. Only 1 patient (0.3%) met criteria for DSM-IV AUD alone. Patients meeting both DSM-5 and DSM-IV criteria had more negative drinking consequences, mental health symptoms and self-reported readiness to change compared with those meeting DSM-5 criteria alone or neither DSM-5 nor DSM-IV criteria. In this sample of primary care patients with frequent heavy drinking, DSM-5 identified 13% more patients with AUD than DSM-IV. This group had a lower mental health symptom burden and less self-reported readiness to change compared to those meeting criteria for both DSM-IV and DSM-5 AUD.

Enumerating all maximal frequent subtrees in collections of phylogenetic trees

Science.gov (United States)

2014-01-01

Background A common problem in phylogenetic analysis is to identify frequent patterns in a collection of phylogenetic trees. The goal is, roughly, to find a subset of the species (taxa) on which all or some significant subset of the trees agree. One popular method to do so is through maximum agreement subtrees (MASTs). MASTs are also used, among other things, as a metric for comparing phylogenetic trees, computing congruence indices and to identify horizontal gene transfer events. Results We give algorithms and experimental results for two approaches to identify common patterns in a collection of phylogenetic trees, one based on agreement subtrees, called maximal agreement subtrees, the other on frequent subtrees, called maximal frequent subtrees. These approaches can return subtrees on larger sets of taxa than MASTs, and can reveal new common phylogenetic relationships not present in either MASTs or the majority rule tree (a popular consensus method). Our current implementation is available on the web at https://code.google.com/p/mfst-miner/. Conclusions Our computational results confirm that maximal agreement subtrees and all maximal frequent subtrees can reveal a more complete phylogenetic picture of the common patterns in collections of phylogenetic trees than maximum agreement subtrees; they are also often more resolved than the majority rule tree. Further, our experiments show that enumerating maximal frequent subtrees is considerably more practical than enumerating ordinary (not necessarily maximal) frequent subtrees. PMID:25061474

Advanced Prostate Cancer Presenting as Hemolytic Uremic Syndrome

R. Ramos

2013-01-01

Full Text Available Introduction. Hemolytic uremic syndrome (HUS is characterized by endothelial dysfunction, consumption thrombocytopenia, microangiopathic hemolytic anemia, and acute renal failure. HUS generally has a dismal prognosis, except when associated with gastroenteritis caused by verotoxin-producing bacteria. Cancer associated HUS is uncommon, and there are only scarce reports on prostate cancer presenting with HUS. Case Presentation. A 72-year-old man presented to the emergency department with oliguria, hematuria, and hematemesis. Clinical evaluation revealed acute renal failure, hemolysis, normal blood-clotting studies, and prostate-specific antigen value of 1000 ng/mL. The patient was started on hemodialysis, ultrafiltration with plasma exchange, and androgen blockade with bicalutamide and completely recovered from HUS. The authors review the 14 published cases on this association. Conclusion. The association of HUS and prostate cancer occurs more frequently in patients with high-grade, clinically advanced prostate cancer. When readily recognized and appropriately treated, HUS does not seem to worsen prognosis in prostate cancer patients.

Seventy-seven frequent attenders at an emergency department (ED) in an inner-city hospital in the UK (defined as seven or more visits in the previous 12 months) were compared with 182 patients who were attending the same department on a routine basis. Patients completed the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) and the Short Form (SF)-36. Information was obtained on 64% of the frequent attenders and 45% underwent a detailed psychiatric assessment. Of the frequent attenders, 45% had psychiatric disorder and 49% had some form of an alcohol-related disorder. Compared with routine attenders, frequent attenders reported lower health status, had more psychiatric disorder (odds ratio: OR=8.2, 95% confidence interval: CI=3.8--18.1), had more general hospital admissions (OR=19.9, 95% CI=8.3--47.8), more psychiatric admissions (OR=167.5, 95% CI=9.5--2959.0), and more GP visits (95% CI for difference=-10.2 to -5.7). There was no evidence that frequent attenders had more somatisation than routine attenders. Specific treatment and management strategies need to be developed for this group of patients, although a substantial proportion may be difficult to engage in the treatment process.

Optic pathway gliomas (OPGs) occur sporadically or in patients with neurofibromatosis type 1 (NF1). The purpose of this study was to evaluate the clinical presentation at diagnosis and at progression of patients with OPGs. We conducted a chart review of patients with OPGs diagnosed in a single center over a period of 15 years. Demographic data including age, sex, NF1 status, clinical presentation, and outcome were collected. Of the 40 patients who were identified, 23 had sporadic tumors (57.5%) and 17 had NF1-related tumors (42.5%). Among the children with NF1, there was a significant overrepresentation of girls (82.3%) (P = 0.02), while among the children without NF1, there were slightly more boys (56.5%) than girls (43.5%). The presence of nystagmus was strongly associated with sporadic optic pathway gliomas. Poor visual outcome was related to tumor affecting both optic pathways, hydrocephalus at diagnosis, and optic nerve atrophy. Of the 40 patients, five died of OPG complications (12.5%) and all had sporadic tumors. Our cohort is one of the largest with OPGs and a detailed description of the clinical presentation both at diagnosis and at progression. We observed a significant difference between sporadic and NF1 optic pathway gliomas in terms of demographics, clinical presentation, and outcome. Copyright © 2017 Elsevier Inc. All rights reserved.

HIV infection treatment strategies have historically defined effectiveness through measuring patient plasma HIV RNA. While combined antiretroviral therapy (cART) can reduce plasma viral load (pVL) to undetectable levels, the degree that HIV is eliminated from other anatomical sites remains unclear. We investigated the HIV DNA levels in 229 varied autopsy tissues from 20 HIV-positive (HIV(+)) cART-treated study participants with low or undetectable plasma VL and cerebrospinal fluid (CSF) VL prior to death who were enrolled in the National Neurological AIDS Bank (NNAB) longitudinal study and autopsy cohort. Extensive medical histories were obtained for each participant. Autopsy specimens, including at least six brain and nonbrain tissues per participant, were reviewed by study pathologists. HIV DNA, measured in tissues by quantitative and droplet digital PCR, was identified in 48/87 brain tissues and 82/142 nonbrain tissues at levels >200 HIV copies/million cell equivalents. No participant was found to be completely free of tissue HIV. Parallel sequencing studies from some tissues recovered intact HIV DNA and RNA. Abnormal histological findings were identified in all participants, especially in brain, spleen, lung, lymph node, liver, aorta, and kidney. All brain tissues demonstrated some degree of pathology. Ninety-five percent of participants had some degree of atherosclerosis, and 75% of participants died with cancer. This study assists in characterizing the anatomical locations of HIV, in particular, macrophage-rich tissues, such as the central nervous system (CNS) and testis. Additional studies are needed to determine if the HIV recovered from tissues promotes the pathogenesis of inflammatory diseases, such as HIV-associated neurocognitive disorders, cancer, and atherosclerosis. It is well-known that combined antiretroviral therapy (cART) can reduce plasma HIV to undetectable levels; however, cART cannot completely clear HIV infection. An ongoing question is

This paper reports on research into the influence of environmental factors (including crowd size, temperature, humidity, and venue type) on the number of patients and the patient problems presenting to first-aid services at large, public events in Australia. Regression models were developed to predict rates of patient presentation and of transportation-to-a-hospital for future mass gatherings. To develop a data set and predictive model that can be applied across venues and types of mass gathering events that is not venue or event specific. Data collected will allow informed event planning for future mass gatherings for which health care services are required. Mass gatherings were defined as public events attended by in excess of 25,000 people. Over a period of 12 months, 201 mass gatherings attended by a combined audience in excess of 12 million people were surveyed throughout Australia. The survey was undertaken by St. John Ambulance Australia personnel. The researchers collected data on the incidence and type of patients presenting for treatment and on the environmental factors that may influence these presentations. A standard reporting format and definition of event geography was employed to overcome the event-specific nature of many previous surveys. There are 11,956 patients in the sample. The patient presentation rate across all event types was 0.992/1,000 attendees, and the transportation-to-hospital rate was 0.027/1,000 persons in attendance. The rates of patient presentations declined slightly as crowd sizes increased. The weather (particularly the relative humidity) was related positively to an increase in the rates of presentations. Other factors that influenced the number and type of patients presenting were the mobility of the crowd, the availability of alcohol, the event being enclosed by a boundary, and the number of patient-care personnel on duty. Three regression models were developed to predict presentation rates at future events. Several

This article aims to report a case of known ectrodactyly ectodermal dysplasia in a young male patient who subsequently was found to have a retinal tear and localized retinal detachment. This is a case report of a 22-year-old white male patient with a history of ectrodactyly ectodermal dysplasia. Our patient initially presented with an acute exacerbation of bilateral, red, irritated eyes. No recent changes in vision were reported. The patient's ocular surface disease was consistent with ectrodermal dysplasia syndrome. However, a dilated fundus examination revealed an asymptomatic retinal tear with a surrounding localized retinal detachment. In this case, the patient presented with longstanding ocular surface disease known to be associated with this patient's inherited ectoderm disorder. In addition, this patient revealed a retinal tear, raising the possibility that patients with inherited congenital ectodermal dysplasia could be at risk for damaged structures originating from the neural ectoderm. In this heterogeneous disease, we are contributing to the existing literature a case of ectodermal dysplasia syndrome with obvious ectodermal complications that also had retinal findings leading us to speculate question if neural ectoderm could also be involved in this inherited disease.

Haemorrhage from Pancreatic Pseudocysts Presenting as Upper Gastrointestinal Haemorrhage

Full Text Available Haemorrhage is a rare but frequently fatal complication of pancreatic pseudocysts. The high mortality associated with pancreatic haemorrhage makes prompt and aggressive management essential. Occasionally, haemorrhage may present atypically, leading to delay in its diagnosis and management. This report details a case of pancreatic haemorrhage presenting as an upper gastrointestinal bleed and discusses the subsequent management. When managing patients with pancreatic pseudocysts who present with the stigmata of upper gastrointestinal bleeding, the possibility that the bleeding originates from the pancreas must always be borne in mind.

Full Text Available Even though intervertebral disc degeneration can be found in the natural course of alkaptonuria, detection of the disease by black disc color change in a patient without any other presentation of alkaptonuria is an exceptionally rare condition. We have reported a very rare case of alkaptonuria presented with low back pain and steppage gait in a 51-year-old male with a complaint of chronic low-back pain and steppage gait who was operated on for prolapsed lumbar disc herniation. Intraoperatively his lumbar disk was discovered to be black. The alkaptonuria diagnosis was considered after histopathological examination of the black disc material and elevated urinary concentration of homogentisic acid confirmed the diagnosis. To our knowledge, this presentation has not been reported previously in literature.

Full Text Available The Korean National Health Insurance, which provides universal coverage for the entire Korean population, is now facing financial instability. Frequent emergency department (ED users may represent a medically vulnerable population who could benefit from interventions that both improve care and lower costs. To understand the nature of frequent ED users in Korea, we analyzed claims data from a population-based national representative sample. We performed both bivariate and multivariable analyses to investigate the association between patient characteristics and frequent ED use (4+ ED visits in a year using claims data of a 1% random sample of the Korean population, collected in 2009. Among 156,246 total ED users, 4,835 (3.1% were frequent ED users. These patients accounted for 14% of 209,326 total ED visits and 17.2% of $76,253,784 total medical expenses generated from all ED visits in the 1% data sample. Frequent ED users tended to be older, male, and of lower socio-economic status compared with occasional ED users (p < 0.001 for each. Moreover, frequent ED users had longer stays in the hospital when admitted, higher probability of undergoing an operative procedure, and increased mortality. Among 8,425 primary diagnoses, alcohol-related complaints and schizophrenia showed the strongest positive correlation with the number of ED visits. Among the frequent ED users, mortality and annual outpatient department visits were significantly lower in the alcohol-related patient subgroup compared with other frequent ED users; furthermore, the rate was even lower than that for non-frequent ED users. Our findings suggest that expanding mental health and alcohol treatment programs may be a reasonable strategy to decrease the dependence of these patients on the ED.

Pheochromocytoma/paraganglioma (PPGL) syndromes associated with polycythemia have previously been described in association with mutations in the von Hippel-Lindau gene. Recently, mutations in the prolyl hydroxylase gene ( PHD ) 1 and 2 and in the hypoxia-inducible factor 2 α ( HIF2A ) were also found to be associated with multiple and recurrent PPGL. Such patients also presented with PPGL and polycythemia, and later on, some presented with duodenal somatostatinoma. In additional patients presenting with PPGL and polycythemia, no further mutations have been discovered. Because the functional imaging signature of patients with PPGL-polycythemia syndromes is still unknown, and because these tumors (in most patients) are multiple, recurrent, and metastatic, the goal of our study was to assess the optimal imaging approach using 4 different PET radiopharmaceuticals and CT/MRI in these patients. Methods: Fourteen patients (10 women, 4 men) with confirmed PPGL and polycythemia prospectively underwent 68 Ga-DOTATATE (13 patients), 18 F-FDG (13 patients), 18 F-fluorodihydroxyphenylalanine ( 18 F-FDOPA) (14 patients), 18 F-fluorodopamine ( 18 F-FDA) (11 patients), and CT/MRI (14 patients). Detection rates of PPGL lesions were compared between all imaging studies and stratified between the underlying mutations. Results: 18 F-FDOPA and 18 F-FDA PET/CT showed similar combined lesion-based detection rates of 98.7% (95% confidence interval [CI], 92.7%-99.8%) and 98.3% (95% CI, 90.9%-99.7%), respectively. The detection rates for 68 Ga-DOTATATE (35.3%; 95% CI, 25.0%-47.2%), 18 F-FDG (42.3; 95% CI, 29.9%-55.8%), and CT/MRI (60.3%; 95% CI, 48.8%-70.7%) were significantly lower ( P < 0.01), irrespective of the mutation status. Conclusion: 18 F-FDOPA and 18 F-FDA are superior to 18 F-FDG, 68 Ga-DOTATATE, and CT/MRI and should be the radiopharmaceuticals of choice in this rare group of patients. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

Full Text Available OBJECTIVE: The purpose of this study was to investigate frequent disease-causing gene mutations in autosomal recessive retinitis pigmentosa (arRP in the Japanese population. METHODS: In total, 99 Japanese patients with non-syndromic and unrelated arRP or sporadic RP (spRP were recruited in this study and ophthalmic examinations were conducted for the diagnosis of RP. Among these patients, whole exome sequencing analysis of 30 RP patients and direct sequencing screening of all CNGA1 exons of the other 69 RP patients were performed. RESULTS: Whole exome sequencing of 30 arRP/spRP patients identified disease-causing gene mutations of CNGA1 (four patients, EYS (three patients and SAG (one patient in eight patients and potential disease-causing gene variants of USH2A (two patients, EYS (one patient, TULP1 (one patient and C2orf71 (one patient in five patients. Screening of an additional 69 arRP/spRP patients for the CNGA1 gene mutation revealed one patient with a homozygous mutation. CONCLUSIONS: This is the first identification of CNGA1 mutations in arRP Japanese patients. The frequency of CNGA1 gene mutation was 5.1% (5/99 patients. CNGA1 mutations are one of the most frequent arRP-causing mutations in Japanese patients.

Globally, breast cancer is the most frequent malignancy in women, and stage at diagnosis is a key determinant of outcome. In low- to middle-income countries, including Nigeria, advanced stage diagnosis and delayed treatment represent a significant problem. That social barriers contribute to delay has been noted in previous research; however, few specific factors have been studied. Using semi-structured interviews, this study identifies social barriers to diagnosis and treatment for patients who presented at University College Hospital Ibadan, Nigeria. Transcripts from the interviews were coded and analysed thematically. Thirty-one patients and five physicians were interviewed. The median age of patients was 51 (range: 28 to above 80), 83% were Christian and 17% were Muslim. Preliminary analysis showed that delays in diagnosis reflected a lack of education as well as the utilisation of non-physician medical services such as pharmacists. Delays in treatment were often due to fear of unanticipated surgery and cost. The majority of women did not know the cause of their breast cancer, but some believed it was caused by a spiritual affliction. This study suggests that further education and awareness of breast cancer for both patients and providers is needed in order to increase early stage diagnosis.

Relapses of nephrotic syndrome often follow minor infections, commonly of the upper respiratory tract. Daily administration of maintenance prednisolone during intercurrent infections was examined to determine whether the treatment reduces relapse rates in children with frequently relapsing nephrotic syndrome. In a randomized controlled trial (nonblind, parallel group, tertiary-care hospital), 100 patients with idiopathic, frequently relapsing nephrotic syndrome eligible for therapy with prolonged low-dose, alternate-day prednisolone with or without levamisole were randomized to either receive their usual dose of alternate-day prednisolone daily for 7 days during intercurrent infections (intervention group) or continue alternate-day prednisolone (controls). Primary outcome was assessed by comparing the rates of infection-associated relapses at 12-month follow-up. Secondary outcomes were the frequency of infections and the cumulative amount of prednisolone received in both groups. Patients in the intervention group showed significantly lower infection-associated (rate difference, 0.7 episodes/patient per year; 95% confidence intervals [CI] 0.3, 1.1) and lower total relapse rates (0.9 episodes/patient per year, 95% CI 0.4, 1.4) without increase in steroid toxicity. Poisson regression, adjusted for occurrence of infections, showed that daily administration of prednisolone during infections independently resulted in 59% reduction in frequency of relapses (rate ratio, 0.41; 95% CI 0.3, 0.6). For every six patients receiving this intervention, one showed a reduction of relapse frequency to less than three per year. Daily administration of maintenance doses of prednisolone, during intercurrent infections, significantly reduces relapse rates and the proportion of children with frequently relapsing nephrotic syndrome.

This retrospective chart review was conducted to determine the presenting signs and symptoms of patients with primary brain tumors diagnosed in the emergency department. There were 101 patients (65 males and 36 females) identified with a hospital discharge diagnosis of primary brain tumor who were admitted through the emergency department. The presenting symptoms included headache (56 patients), altered mental status (51 patients), ataxia (41 patients), nausea or vomiting (37 patients), weakness (27 patients), speech deficits (21 patients), and sensory abnormalities (18 patients). The presenting signs included motor weakness (37 patients), ataxia (37 patients), papilledema (28 patients), cranial nerve palsies (26 patients), visual deficits (20 patients), and speech deficits (12 patients). The average age was 42.8 years, with a range of 3 days to 88 years. The majority of tumors were malignant astrocytomas. Tumor location was cortical in 68 patients, subcortical in 9 patients, and brainstem or cerebellum in 24 patients. In conclusion, patients of all ages may present to the emergency department with a variety of symptoms resulting from a primary brain tumor. Headache and altered mental status were common in our series of patients, but symptoms will depend on the size, location, and type of tumor. A complete neurologic examination is essential, including evaluation for papilledema.

Patient candidacy for acute stroke intervention, is currently assessed using brain computed tomography angiography (CTA) evidence of significant stenosis/occlusion (SSO) with a high National Institutes of Health Stroke Scale (NIHSS) (>6). This study examined the association between CTA without significant stenosis/occlusion (NSSO) and lower NIHSS (≤ 6) with transient ischemic attack (TIA) and other good clinical outcomes at discharge. Patients presenting TIA, modified Rankin Score [mRS] ≤ 1, and home as the discharge disposition. Eighty-five patients received both an NIHSS at presentation and a CTA at 4.2 ± 2.2 hours from stroke symptom onset. Patients with NSSO on CTA as well as those with NIHSS≤6 had better outcomes at discharge (pTIA (pTIA. Addition of NIHSS ≤ 6 to NSSO on CTA proved to be a stronger independent predictor of TIA (Adjusted OR 18.7 95% CI: 3.5-98.9, p=0.001).

A proportion of trauma patients present for evaluation in a delayed fashion after injury, likely due to a variety of medical and nonmedical reasons. There has been little investigation into the characteristics and outcomes of trauma patients who present delayed. We hypothesize that trauma patients who present in a delayed fashion are a unique population at risk of increased trauma-related complications. This was a retrospective review from 2010-2015 at a Level I trauma center. Patients were termed delayed if they presented >24 hours after injury. Patients admitted within 24 hours of their injury were the comparison group. Charts were reviewed for demographics, mechanism, comorbidities, complications and outcomes. A subgroup analysis was done on patients who suffered falls. During the 5-y period, 11,705 patients were admitted. A total of 588 patients (5%) presented >24 h after their injury. Patients in the delayed group were older (65 versus 55 y, P fashion have unique characteristics and are more likely to suffer negative outcomes including substance withdrawal. Future goals will include exploring strategies for early intervention, such as automatic withdrawal monitoring and social work referral for all patients who present in a delayed fashion.

2014-01-01

Aim: To determine the incidence of missed femoral head avascular necrosis (AVN) on pelvic computed tomography (CT) performed for clinical indications other than assessment for AVN. Materials and methods: The study was a Health Insurance Portability and Accountability Act (HIPAA)-compliant retrospective study. The picture archiving and communication system (PACS) database was queried for patients with diagnosis of femoral head AVN on magnetic resonance imaging (MRI), who also underwent pelvic multidetector CT after or <30 days before the MRI examination. The MRI and CT images of 144 hips of 72 patients (39 patients with reported AVN on MRI and 33 age-matched controls; mean age = 60 years, 28 male, 44 female), were reviewed in consensus by two readers in a randomized, blinded manner. Using MRI-proven CT-visible AVN as a reference standard, the incidence of missed AVN on initial CT interpretation was determined. Results: Readers confirmed AVN in 33 patients on the MRI images. Nine hips with AVN underwent joint replacement of the affected joint(s) prior to subsequent CT and were excluded. Forty-three MRI-proven AVN cases in 28 patients (15 bilateral, 13 unilateral) were available for analysis. The study readers diagnosed 35/43 (81%) MRI-proven AVN cases in 22/28 (79%) patients. Four of the 35 (11%) cases of MRI-proven, CT-visible AVN were prospectively reported in 3/22 (14%) patients at initial clinical interpretation, with a miss rate of 89% per hip and 86% per patient. Conclusion: Multidetector CT has high accuracy for detection of AVN; however, this is frequently missed as an incidental finding (89% missed in the present study). Assessment for signs of femoral AVN should be part of routine search pattern in interpretation of pelvic CT

Purpose Hospitalized patients with cancer are considered to be at high risk for venous thromboembolism (VTE). Despite strong recommendations in numerous clinical practice guidelines, retrospective studies have shown that pharmacologic thromboprophylaxis is underutilized in hospitalized patients with cancer. Patients and Methods We conducted a prospective, cross-sectional study of hospitalized patients with cancer at five academic hospitals to determine prescription rates of thromboprophylaxis and factors influencing its use during hospitalization. Results A total of 775 patients with cancer were enrolled across five academic medical centers. Two hundred forty-seven patients (31.9%) had relative contraindications to pharmacologic prophylaxis. Accounting for contraindications to anticoagulation, the overall rate of pharmacologic thromboprophylaxis was 74.2% (95% CI, 70.4% to 78.0%; 392 of 528 patients). Among the patients with cancer without contraindications for anticoagulation, individuals hospitalized with nonhematologic malignancies were significantly more likely to receive pharmacologic thromboprophylaxis than those with hematologic malignancies (odds ratio [OR], 2.34; 95% CI, 1.43 to 3.82; P = .007). Patients with cancer admitted for cancer therapy were significantly less likely to receive pharmacologic thromboprophylaxis than those admitted for other reasons (OR, 0.37; 95% CI, 0.22 to 0.61; P < .001). Sixty-three percent of patients with cancer classified as low risk, as determined by the Padua Scoring System, received anticoagulant thromboprophylaxis. Among the 136 patients who did not receive anticoagulation, 58.8% were considered to be high risk by the Padua Scoring System. Conclusion We conclude that pharmacologic thromboprophylaxis is frequently administered to hospitalized patients with cancer but that nearly one third of patients are considered to have relative contraindications for prophylactic anticoagulation.

Purpose: To study the presenting signs of Retinoblastoma in Egypt at Egypt’s main pediatric oncology referral center. Methods: This is a prospective descriptive study (hospital-based registry) conducted at Children’s Cancer Hospital Egypt between July 2007 and December 2012. Results: Out of 262 patients diagnosed with retinoblastoma, 244 were suffering from intra-ocular disease at presentation. One hundred thirty-nine (57%) patients presented with unilateral disease, while 105 (43%) suffered bilateral disease. The mean age at presentation was 20.6 ± 17 months, averaging 18.87 ± 11.76 months for bilateral and 25.72 ± 18.78 months for unilateral disease. The most common clinical presentation was leukocoria in 180 (73.8%) patients, strabismus in 32 (13.1%) patients and decreased visual acuity in 12 (4.9%) patients. Group D and E disease represented 62% of all affected eyes. Patients with advanced disease (Group C–E) had longer duration of symptoms.Conclusion: In Egypt, retinoblastoma patients present more frequently with advanced disease. There is an ever-increasing need to develop a national team dedicated to studying disease significance and formulating a national awareness program.

Varied appearance of lymphoma in patients with AIDS

Lymphoma is frequently present in patients with acquired immunodeficiency (AIDS). But unlike in the general population, the appearance of lymphoma in patients with AIDS is extremely varied. The computed tomographic scans, chest radiographs, and subsequent hospital courses of 15 patients with AIDS-related lymphoma are presented. The patients presented with isolated pleural effusion (six patients), pleural and pericardial effusion (one patient), pulmonary infiltrates (five patients), and mediastinal adenopathy (three patients). This varied manner of presentation of lymphoma in AIDS patients should be recognized if diagnosis is to be made in the earlier stages of presentation

Neoplasm is an uncommon cause of a parkinsonian syndrome. We report a woman with primary brain B-cell lymphoma presenting as Parkinson's disease. After 1 year of the illness, CT and MRI showed lesions without mass effect in the basal ganglia and corpus callosum. The patient did not respond to levodopa and right cerebellar and brain-stem signs appeared, which prompted further neuroimaging, showing an increase in size of the lesions and a right cerebellar and pontine mass. Stereotactic biopsy of the basal ganglia showed high-grade B-cell lymphoma. Despite the basal ganglia frequently being involved in lymphoma of the brain, presentation with typical or atypical parkinsonism is exceptional. (orig.)

Signs and symptoms of thyrotoxicosis are not specific, and thyroid function tests are frequently prescribed to recognize such thyroid dysfunction. Ultrasensitive assays of thyroid-stimulating hormone (TSH) allow early diagnosis and identification of mild hyperthyroidism (generally designed as 'subclinical'). The aim of this study was to re-evaluate the clinical picture of thyrotoxicosis in the context of the current large utilization of ultrasensitive TSH assays. Prospective descriptive cohort. Clinical presentation of 1572 patients with a recent (symptoms, hormonal evaluation and treatment. A total of 1240 (78·9%) patients were women, mean age 48 ± 17 years. Subclinical hyperthyroidism (SCHT) was present in 86 patients (10·4%). Symptoms of thyrotoxicosis were in decreasing frequency order: palpitations, weakness, heat-related signs and disturbed sleep. A total of 64·9% of patients had lost weight. Signs and symptoms were more frequent in Graves' disease, in young patients, and were partially related to biochemical severity. Symptoms were less frequent in elderly patients except for cardiac manifestations (atrial fibrillation). Most patients with SCHT had one or several signs or symptoms of thyrotoxicosis. This study confirms that elderly patients have less symptoms of thyrotoxicosis than younger subjects but are at increased risk of cardiac complications. Our results show that most patients with 'subclinical' HT have in fact signs or symptoms of thyrotoxicosis. © 2015 John Wiley & Sons Ltd.

Frequent hemodialysis is currently conducted in a limited number of pediatric dialysis centers. However, the preliminary experience with children who have undergone procedures such as "daily" intensive hemodiafiltration and nocturnal hemodialysis has been positive, with the allowance for unrestricted diets and fluid intake, the lack of need for phosphate binders, excellent metabolic and blood pressure control, and, in the case of hemodiafiltration, excellent growth. The provision of frequent daily hemodialysis with the NxStage System has also recently been introduced to pediatrics. An overview about what is currently understood regarding the technical and clinical application of these approaches to therapy for children with end-stage renal disease form the basis for this article and highlight the impact of the procedures to date and the need for additional experience and collaborative data collection.

Kaposi’s Sarcoma Presenting as Lymphadenopathy in an Immunocompetent Patient

Full Text Available Introduction: Kaposi’s sarcoma (KS is an angioproliferative disorder first described in 1872 by Moritz Kaposi. Four main clinical presentations of KS have been described: classic, endemic, iatrogenic and epidemic. KS involvement of the lymph nodes is extremely uncommon in the classical variant form, especially if it precedes the skin manifestations. We describe the case of an elderly HIV-negative patient presenting with lymphadenopathy who was found to have KS. Case Report: A 67-year-old patient was admitted for exploration of polyadenopathies in the context of a general decline in health. Physical examination revealed an erythematosus left lower limb rash associated with angiomatous nodules and multiple lymphadenopathies. The diagnosis of erysipelas in the left leg was retained and the patient was treated with good evolution of the rash but persistence of the angiomatous nodules and the polyadenopathies. Skin and lymph node biopsies led to a diagnosis of KS. The patient is proposed for polychemotherapy. Conclusion: KS must be suspected in lymphadenopathies despite the absence of typical cutaneous signs of the disease and in immunocompetent patients.

To study the efficacy and safety of tenoten in the preventive treatment of frequent episodic tension-type headache (FETHA) compared to patients treated with pain relievers. A study included 60 patients with FETHA. Patients of the main group (n=30) received tenoten in addition to standard treatment. The study comprised 3 visits: beginning of treatment, after one month and after three months. All patients underwent physical and clinical/neurological examinations. In each visit, treatment efficacy was assessed according the following parameters: VAS scores (0-10) for assessment of pain and tension in pericranial muscles in 6 standard points, mean frequency and duration of the headache episode, quality of life indices, Beck depression scores, Spilberger trait and state anxiety, autonomic symptom severity, parameters of sleep disorders, frequency of adverse effects, CGI scores (0-7). Tenoten as a preventive medication reduced the frequency of headache episodes that allowed to diagnose patients with rare episodic tension-type headache in the end of treatment. At the same time, there was a significant reduction in headache intensity during the episode and decrease in amount of analgesics used by the patients.

Familial Creutzfeldt-Jakob disease (fCJD) in Jews of Libyan ancestry is caused by an E200K mutation in the PRNP gene. The typical presenting symptoms include cognitive decline, behavioral changes and gait disturbances; however, some patients may have an unusual presentation such as a stroke-like presentation, alien hand syndrome or visual disturbances. The aim of this paper is to describe uncommon presentations in our series of consecutive patients with E200K fCJD. The study group included consecutive fCJD patients followed up as part of a longitudinal prospective study ongoing since 2003 or hospitalized since 2005. The clinical diagnosis of probable CJD was based on accepted diagnostic criteria and supported by typical magnetic resonance imaging, electroencephalographic findings, elevated cerebrospinal fluid tau protein levels and by genetic testing for the E200K mutation. Disease symptoms and signs were retrieved from the medical files. The study population included 77 patients (42 men) with a mean age of disease onset of 60.6 ± 7.2 years. The most prevalent presenting symptoms were cognitive decline followed by gait impairment and behavioral changes. However, six patients had an unusual presentation including auditory agnosia, monoparesis, stroke-like presentation, facial nerve palsy, pseudobulbar syndrome and alien hand syndrome. Our case series illustrates the wide phenotypic variability of the clinical presentation of patients with fCJD and widens the clinical spectrum of the disease. A high level of clinical suspicion may prove useful in obtaining early diagnosis and therefore avoiding costly and inefficient diagnostic and therapeutic strategies. © 2016 EAN.

The aim of this paper was to identify the key factors of case management (CM) interventions among frequent users of healthcare services found in empirical studies of effectiveness. Thematic analysis review of CM studies. We built on a previously published review that aimed to report the effectiveness of CM interventions for frequent users of healthcare services, using the Medline, Scopus and CINAHL databases covering the January 2004-December 2015 period, then updated to July 2017, with the keywords 'CM' and 'frequent use'. We extracted factors of successful (n=7) and unsuccessful (n=6) CM interventions and conducted a mixed thematic analysis to synthesise findings. Chaudoir's implementation of health innovations framework was used to organise results into four broad levels of factors: (1) ,environmental/organisational level, (2) practitioner level, (3) patient level and (4) programme level. Access to, and close partnerships with, healthcare providers and community services resources were key factors of successful CM interventions that should target patients with the greatest needs and promote frequent contacts with the healthcare team. The selection and training of the case manager was also an important factor to foster patient engagement in CM. Coordination of care, self-management support and assistance with care navigation were key CM activities. The main issues reported by unsuccessful CM interventions were problems with case finding or lack of care integration. CM interventions for frequent users of healthcare services should ensure adequate case finding processes, rigorous selection and training of the case manager, sufficient intensity of the intervention, as well as good care integration among all partners. Other studies could further evaluate the influence of contextual factors on intervention impacts. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Muscle pains with or without CK-elevation are among the most frequently observed side-effects in patients with hyperlipoproteinemia on various statins. The pathophysiological background, however, remains obscure. We examined isoprostane 8-epi-PGF2alpha, a marker of in-vivo oxidation injury, in plasma, serum and urine in these patients at baseline, when muscle problems manifested and different time intervals after withdrawing the respective statin. A healthy control group and a group of untreated patients with hyperlipoproteinemia were run as controls. The majority of patients with muscular side-effects show elevated 8-epi-PGF2alpha in plasma and urine, whereas serum values were elevated only to a lesser extent. Stopping statin therapy or successfully changing to another member of this family of compounds resulted in a normalization of the values in all patients. These findings indicate a significant involvement of oxidative injury in the muscular side-effects of statins in patients suffering from hyperlipoproteinemia.

Breast cancer is the most common cancer, and one of the leading causes of death for females in Jordan and many countries in the world. Studies have shown that delay in symptoms presentation, diagnosis or treatment would result in poor prognosis. There has been no published study from Jordan on delays in patient presentation, delays in diagnosis, or delays in treatment. Therefore, we conducted this study to assess these important quality indicators aiming to improve prognosis for breast cancer patients in Jordan. This project was a cross-sectional study on female breast cancer patients in Jordan. The total number of participants was 327. The proportion of patients with presentation delay, diagnosis delay, and treatment delay was 32.2%, 49.1%, or 32.4%, respectively. The main reported reasons for delay in presentation were ignorance of the nature of the problem (65.6%), limited/lack of knowledge that symptoms were suggestive of cancer diagnosis (16.7%), and misdiagnosis (16.7%). Predictors of delay and mean time for presentation, diagnosis, and treatment were identified. Our results reveal that breast cancer patients in Jordan are experiencing delays in presentation, diagnosis, and treatment. This could justify the advanced stages at diagnosis and poor outcomes for breast cancer patients in Jordan. We recommend revising the current early detection and down-staging programs in Jordan. © 2015 Wiley Periodicals, Inc.

While there is enough convincing evidence in childhood acute lymphoblastic leukemia (ALL), the data on the pre-natal origin in childhood acute myeloid leukemia (AML) are less comprehensive. Our study aimed to screen Guthrie cards (neonatal blood spots) of non-infant childhood AML and ALL patients for the presence of their respective leukemic markers. We analysed Guthrie cards of 12 ALL patients aged 2–6 years using immunoglobulin (Ig) and T-cell receptor (TCR) gene rearrangements (n = 15) and/or intronic breakpoints of TEL/AML1 fusion gene (n = 3). In AML patients (n = 13, age 1–14 years) PML/RARalpha (n = 4), CBFbeta/MYH11 (n = 3), AML1/ETO (n = 2), MLL/AF6 (n = 1), MLL/AF9 (n = 1) and MLL/AF10 (n = 1) fusion genes and/or internal tandem duplication of FLT3 gene (FLT3/ITD) (n = 2) were used as clonotypic markers. Assay sensitivity determined using serial dilutions of patient DNA into the DNA of a healthy donor allowed us to detect the pre-leukemic clone in Guthrie card providing 1–3 positive cells were present in the neonatal blood spot. In 3 patients with ALL (25%) we reproducibly detected their leukemic markers (Ig/TCR n = 2; TEL/AML1 n = 1) in the Guthrie card. We did not find patient-specific molecular markers in any patient with AML. In the largest cohort examined so far we used identical approach for the backtracking of non-infant childhood ALL and AML. Our data suggest that either the prenatal origin of AML is less frequent or the load of pre-leukemic cells is significantly lower at birth in AML compared to ALL cases

To exmaine the distribution of age, gender, time between onset and presentation, clinical findings, predisposing factors, platelet distribution width, mean platelet volume values and neuroimaging findings, together with the treatment regime and the outcome for patients of cerebral venous sinus thrombosis. Methods: The retrospective, descriptive cross-sectional study was conducted at Yuzuncu Yil University, Medical Faculty Hospital in Van, Turkey, comprising 51 cases diagnosed with cerebral venous sinus thrombosis between January 2008 and September 2011. The diagnosis was based on the results of clinical evaluation, cranial magnetic resonance imaging and venography. SPSS 16 was used for statistical analysis. Results: Overall, 43 (84.3%) of the cases were female, and 8 (15.7%) were male. The average age was 32+-11.13 years. The most frequent symptom was headache in 41 (80.4%) cases. The postpartum period was one of the most observed predisposing factors in 17 (33.3%) patients. The magnetic resonance imaging was normal in 35 (68.6%) cases, but in all of the cases, magnetic resonance venography was abnormal. Topographically, the most frequent involvement was transverse sinus in 40 (78.4%) cases. Besides, 50 (98%) patients were discharged following full recovery or mild sequela and only 1 (2%) case had severe sequela. Conclusion: Patients presenting with headache should be examined carefully in the emergency department. Early diagnosis and treatment with clinical and neuroimaging techniques for such patients is recommended. (author)

Acute unstable depressive syndrome (AUDS is associated more frequently with epilepsy than major depression

2010-07-01

Full Text Available Abstract Background Depressive disorders are frequent in epilepsy and associated with reduced seizure control. Almost 50% of interictal depressive disorders have to be classified as atypical depressions according to DSM-4 criteria. Research has mainly focused on depressive symptoms in defined populations with epilepsy (e.g., patients admitted to tertiary epilepsy centers. We have chosen the opposite approach. We hypothesized that it is possible to define by clinical means a subgroup of psychiatric patients with higher than expected prevalence of epilepsy and seizures. We hypothesized further that these patients present with an Acute Unstable Depressive Syndrome (AUDS that does not meet DSM-IV criteria of a Major Depressive Episode (MDE. In a previous publication we have documented that AUDS patients indeed have more often a history of epileptic seizures and abnormal EEG recordings than MDE patients (Vaaler et al. 2009. This study aimed to further classify the differences of depressive symptoms at admittance and follow-up of patients with AUDS and MDE. Methods 16 AUDS patients and 16 age- and sex-matched MDE patients were assessed using the Symptomatic Organic Mental Disorder Assessment Scale (SOMAS, the Montgomery and Åsberg Depression Rating Scale (MADRS, and the Mini-Mental State Test (MMST, at day 2, day 4-6, day 14-16 and 3 months after admittance to a psychiatric emergency unit. Life events were assessed with The Social Readjustment Rating Scale (SRRS and The Life Experience Survey (LES. We also screened for medication serum levels and illicit drug metabolites in urine. Results AUDS patients had significantly higher SOMAS scores (average score at admission 6.6 ± 0.8, reflecting increased symptom fluctuation and motor agitation, and decreased insight and concern compared to MDE patients (2.9 ± 0.7; p Conclusions AUDS patients present with rapidly fluctuating mood symptoms, motor agitation and relative lack of insight and concern.

The objective of the present study was to estimate the influence of gastroesophageal reflux disease (GERD) on the pH values in the pharynx and nose. It included 87 patients at the age varying from 18 to 81 years admitted to the Irkutsk-based Railway Clinical Hospital and allocated to four groups. Group 1 was comprised of 25 patients presenting with gastroesophageal reflux disease and chronic rhinosinusitis (CRS), group 2 consisted of 29 patients with CRS in the absence of GERD, group 3 included 22 patients with nasal septum deformations (NSD) and GERD, group 4 included 11 patients with NSD and motor rhinitis without GERD. The control group was formed from 10 volunteers. pH was measured by the contact method with the use ofEkokhim indicator paper. Gastroesophageal reflux disease was diagnosed following the recommendations of the Montreal consensus. It was shown that pH values in the pharynx of the patients with compromised nasal breathing of any origin in combination with GERD were lower than in the absence of GERD and in the healthy volunteers. The study groups did not differ in terms of pH values in the nasal cavity. It is concluded that pH values 4 or lower may serve as the criterion for pharyngo-laryngeal reflux (PLR) concomitant with HERD while pH 5 occurs more frequently in the patients with compromised nasal breathing of any etiology, regardless of the presence or absence of GERD.Disordered nasal breathing of any genesis in the patients presenting with gastroesophageal reflux disease was associated with the feeling of the lump in the throat, congestion of the respiratory tract and the nose, pain in the ears, cardialgia, and irregular heartbeat. It isrecommended to use pH measurements as a criterion for diagnostics of pharyngo-laryngeal reflux in the patients presenting with gastroesophageal reflux disease.

In March 2014, the World Health Organization was notified of an outbreak of Zaire ebolavirus in a remote area of Guinea. The outbreak then spread to the capital, Conakry, and to neighboring countries and has subsequently become the largest epidemic of Ebola virus disease (EVD) to date. From March 25 to April 26, 2014, we performed a study of all patients with laboratory-confirmed EVD in Conakry. Mortality was the primary outcome. Secondary outcomes included patient characteristics, complications, treatments, and comparisons between survivors and nonsurvivors. Of 80 patients who presented with symptoms, 37 had laboratory-confirmed EVD. Among confirmed cases, the median age was 38 years (interquartile range, 28 to 46), 24 patients (65%) were men, and 14 (38%) were health care workers; among the health care workers, nosocomial transmission was implicated in 12 patients (32%). Patients with confirmed EVD presented to the hospital a median of 5 days (interquartile range, 3 to 7) after the onset of symptoms, most commonly with fever (in 84% of the patients; mean temperature, 38.6°C), fatigue (in 65%), diarrhea (in 62%), and tachycardia (mean heart rate, >93 beats per minute). Of these patients, 28 (76%) were treated with intravenous fluids and 37 (100%) with antibiotics. Sixteen patients (43%) died, with a median time from symptom onset to death of 8 days (interquartile range, 7 to 11). Patients who were 40 years of age or older, as compared with those under the age of 40 years, had a relative risk of death of 3.49 (95% confidence interval, 1.42 to 8.59; P=0.007). Patients with EVD presented with evidence of dehydration associated with vomiting and severe diarrhea. Despite attempts at volume repletion, antimicrobial therapy, and limited laboratory services, the rate of death was 43%.

Doege-Potter syndrome presenting with hypoinsulinemic hypoglycemia in a patient with a malignant extrapleural solitary fibrous tumor: a case report

Directory of Open Access Journals (Sweden)

Schutt Robert C

2013-01-01

Full Text Available Abstract Introduction Doege-Potter syndrome is a paraneoplastic syndrome characterized by non-islet cell tumor hypoglycemia secondary to a solitary fibrous tumor. This tumor causes hypoglycemia by the secretion of a prohormone form of insulin-like growth factor II. We describe the diagnosis and management of Doege-Potter syndrome and the use of transarterial chemoembolization in a patient with a malignant extrapleural solitary fibrous tumor. Case presentation Our patient was a 64-year-old Caucasian woman who initially presented with urinary incontinence and was found to have a 14.5×9.0×9.0cm retroperitoneal solitary fibrous tumor compressing her bladder. Her tumor was surgically resected but recurred with multiple hepatic metastatic lesions. The hepatic metastases progressed despite systemic chemotherapy and treatment with doxorubicin transarterial chemoembolization. Her course was complicated by the development of recurrent fasting hypoglycemia, most likely secondary to Doege-Potter syndrome. Her hypoglycemia was managed with corticosteroid therapy and frequent scheduled nutrient intake overnight. Conclusions The rarity of hepatic solitary fibrous tumors and consequent lack of controlled trials make this report significant in that it describes the diagnostic approach to Doege-Potter syndrome, describes our experience with the use of doxorubicin transarterial chemoembolization, and presents management options for tumor-associated hypoglycemia in the case of extensive disease not amenable to surgical resection.

Objectives. To identify 1 the characteristics of patients receiving non acute (inappropriate care and 2 the variables associated to inappropriate hospital use, in order to 3 estimate the relevance of the problem and to 4 focus future concurrent reviews and efforts to allocate patients to alternative health care settings.

Design. A prospective review of a random sample of adult patients who presented to the Emergency Department of the Molinette Hospital. Patients were assessed at admission and on day 3, 5and 8 using the Appropriateness Evaluation Protocol (Italian validated version. Patients: 490 overall; 312 (64 % medical and 178 (36 % surgical.

Outcome measures. Acute (appropriate and non acute (inappropriate admissions, Major Disease Category, costs, mean weights of Diagnosis Related Groups, and length of stay (days.

Results. The proportion of patients requiring acute care declined rapidly from presentation (84.5% to the fifth day of admission (60.9%. Patients admitted during weekends showed a higher rate of inappropriate stay on day 5 (P=0.04. The proportion of inappropriate admissions was higher for medical rather than surgical patients (P=0.07 at presentation and at day 5 (P < 0.01. Traditional social-demographic variables were not significant risk indicators for inappropriate admissions. The likelihood ratio for inappropriate admission at presentation was significantly higher for minor illnesses and disturbances (P=0.03.

Inappropriate stay on day 5 was significantly associated with lower cost (P < 0.01, lower mean DRG weight (P < 0.01 and shorter length of stay (P=0.05 for medical but not for surgical admissions.

Conclusions. Traditional epidemiological indicators are inadequate to target prospective concurrent reviews. Qualitative studies focusing on patient physician dialogue in different situations and contexts could

that frequent pattern mining was at the cradle of subspace clustering—yet, it quickly developed into an independent research field. In this chapter, we discuss how frequent pattern mining algorithms have been extended and generalized towards the discovery of local clusters in high-dimensional data......Discovering clusters in subspaces, or subspace clustering and related clustering paradigms, is a research field where we find many frequent pattern mining related influences. In fact, as the first algorithms for subspace clustering were based on frequent pattern mining algorithms, it is fair to say....... In particular, we discuss several example algorithms for subspace clustering or projected clustering as well as point out recent research questions and open topics in this area relevant to researchers in either clustering or pattern mining...

RASopathies are a heterogeneous group of genetic syndromes characterized by mutations in genes that regulate cellular processes, including proliferation, differentiation, survival, migration, and metabolism. Excluding congenital heart defects, hypertrophic cardiomyopathy is the most frequent cardiovascular defect in patients affected by RASopathies. A worse outcome (in terms of surgical risk and/or mortality) has been described in a specific subset of Rasopathy patients with early onset, severe hypertrophic cardiomyopathy presenting with heart failure. New short-term therapy with a mammalian target of rapamycin inhibitor has recently been used to prevent heart failure in these patients with a severe form of hypertrophic cardiomyopathy.

Integrating Entropy and Closed Frequent Pattern Mining for Social Network Modelling and Analysis

Science.gov (United States)

Adnan, Muhaimenul; Alhajj, Reda; Rokne, Jon

The recent increase in the explicitly available social networks has attracted the attention of the research community to investigate how it would be possible to benefit from such a powerful model in producing effective solutions for problems in other domains where the social network is implicit; we argue that social networks do exist around us but the key issue is how to realize and analyze them. This chapter presents a novel approach for constructing a social network model by an integrated framework that first preparing the data to be analyzed and then applies entropy and frequent closed patterns mining for network construction. For a given problem, we first prepare the data by identifying items and transactions, which arc the basic ingredients for frequent closed patterns mining. Items arc main objects in the problem and a transaction is a set of items that could exist together at one time (e.g., items purchased in one visit to the supermarket). Transactions could be analyzed to discover frequent closed patterns using any of the well-known techniques. Frequent closed patterns have the advantage that they successfully grab the inherent information content of the dataset and is applicable to a broader set of domains. Entropies of the frequent closed patterns arc used to keep the dimensionality of the feature vectors to a reasonable size; it is a kind of feature reduction process. Finally, we analyze the dynamic behavior of the constructed social network. Experiments were conducted on a synthetic dataset and on the Enron corpus email dataset. The results presented in the chapter show that social networks extracted from a feature set as frequent closed patterns successfully carry the community structure information. Moreover, for the Enron email dataset, we present an analysis to dynamically indicate the deviations from each user's individual and community profile. These indications of deviations can be very useful to identify unusual events.

Intestinal duplications are rare developmental anomalies that can occur anywhere along the gastrointestinal tract. Rectal duplication cysts account for approximately 4% of all duplication cysts. They usually present in childhood with symptoms of mass effect, local infection or more rarely with rectal bleeding from ectopic gastric mucosa. A 26year old male presented with a history of bright red blood per rectum. On examination a mucosal defect with an associated cavity adjacent to the rectum was identified. This was confirmed with rigid proctoscopy and CT scan imaging. A complete transanal excision was performed. Rectal duplication cysts are more common in pediatric patients. They more frequently present with symptoms of mass effect or local infection than with rectal bleeding. In adult patients they are a rare cause of rectal bleeding. Definitive treatment is with surgical excision. A transanal, transcoccygeal, posterior sagittal or a combined abdominoperineal approach may be used depending on anatomic characteristics of the duplication cyst. We present a rare case of a rectal duplication cyst presenting in adulthood with rectal bleeding, managed with transanal excision. Published by Elsevier Ltd.

This review focuses on frequent users (FUs) of the emergency department (ED). Elucidation of the characteristics of frequent ED users will help to improve healthcare services. A systematic review of the literature (from 1999 onwards) on frequent ED users in non-US hospitals was performed. Twenty-two studies were included. FUs are responsible for a wide variety of 1-31% of ED visits depending on the FU definition used. They have a mean age between 40 and 50 years and are older than nonfrequent users. Chronic physical and mental diseases seem to be the main reasons for frequent ED visits. In terms of social characteristics, lacking a partner is more frequently reported among FUs in some studies. The absence of a universal definition for FUs complicates the determination of the burden on emergency healthcare services. FUs are a heterogeneous group of patients with genuine medical needs and high consumption of other healthcare services.

To describe acute toxicity of recreational drugs including novel psychoactive substances. We included all cases presenting at the emergency department (ED) of the University Hospital of Basel, Switzerland, between October 2013 and September 2014 with acute toxicity due to self-reported recreational drug use or with symptoms/signs consistent with acute toxicity. Isolated ethanol intoxications were excluded. Intoxications were confirmed with immunoassays and liquid chromatography coupled with mass spectrometry (LC-MS/MS), which also detected novel psychoactive substances. Among the 47,767 attendances at the ED, 216 were directly related to acute toxicity of recreational drugs. The mean patient age was 31 years and 69% were male. Analytical drug confirmation was available in 180 cases. Most presentations were related to cocaine (36%), cannabis (31%), opioids (13%), 3,4-methylenedioxy-methamphetamine (MDMA, 9%), other amphetamines (7%), benzodiazepines (7%), and lysergic acid diethylamide (LSD, 5%). The substances most commonly detected analytically were cannabis (37%), cocaine (33%), opioids (29%), benzodiazepines (21%), and amphetamines including MDMA (13%). Notably, there were only two cases of novel psychoactive substances (2,5-dimethoxy-4-bromophenethylamine [2C-B] and pentylone). The most frequent symptoms were tachycardia (31%), anxiety (27%), nausea or vomiting (23%), and agitation (22%). Severe complications included myocardial infarction (2), psychosis (10), seizures (10), and 1 fatality. Most patients were discharged home (68%), 8% were admitted to intensive care and 9% were referred to psychiatric care. Medical problems related to illicit drugs mostly concerned cocaine and cannabis and mainly involved sympathomimetic toxicity and/or psychiatric disorders. ED presentations associated with novel psychoactive substances appeared to be relatively rare.

The presence of tumor thrombus in the right atrium is frequently the result of direct intraluminal extension of infra-diaphragmatic malignancy into the inferior vena cava (IVC) or supradiaphragmatic carcinoma into the superior vena cava (SVC). Right atrial tumor thrombus with extension into both SVC and IVC has not been reported in the literature. We present a patient who presented with symptoms of right atrial and SVC obstruction. Imaging revealed presence of a thrombus in the right atrium, extending to the SVC and IVC, with the additional findings of a left adrenal mass and multiple liver lesions. The histopathological examination of the right atrial mass revealed metastatic adenocarcinoma cells. The patient was given a presumptive diagnosis of metastatic adenocarcinoma, most likely adrenal in origin, with multiple hepatic lesions suspicious for metastasis. The clinical outcome of the patient was not favorable; the patient succumbed before the adrenal mass could be confirmed to be the primary tumor. This case highlights that in patients manifesting with extensive cavoatrial thrombus as, the existence of primary carcinoma should be considered especially in the adrenal cortex or in the lung

Although health literacy and quality of life are important concepts in health care, the link between them is unclear, especially for a population of frequent users of health care services with chronic diseases. Low health literacy is a common problem that has been linked to several negative health outcomes. Quality of life is an important health outcome in patient-centered care. Frequent users of health care services are a vulnerable population that deserves attention due to high costs and negative outcomes such as lower quality of life and higher mortality. The objective of this study was to examine the relationship between health literacy and the physical and mental components of quality of life among frequent users of health care services with chronic diseases. This study presents the cross-sectional analysis of data collected through the V1SAGES project, a randomized controlled trial on the effectiveness of a case management intervention in primary care in Quebec, Canada. Participants (n = 247) were frequent users of health care services presenting at least one chronic condition. Health literacy was measured by the Newest Vital Sign (NVS), and the physical and mental components of quality of life were evaluated by the Short Form Health Survey Version 2 (SF-12v2). The association between health literacy (independent variable) and the physical and mental components of quality of life was examined using biserial correlation. No association was found between health literacy and quality of life (physical component: r = 0.108, ρ = 0.11; mental component: r = 0.147, ρ = 0.15). This study suggests that there is no relationship between health literacy and the physical and mental components of quality of life among frequent users of health care services. NCT01719991 .

To clarify the phenotypic variability of Coffin-Siris syndrome, we present a review of the literature and 18 new cases. We performed a questionnaire study of patients ascertained through an international support group. Information on their sibs was available for comparison. The most frequent findings include some degree of mental retardation or developmental delay, "coarse" facial appearance, feeding difficulties, frequent infections, and hypoplastic to absent fifth fingernails and fifth distal phalanges. We discuss the key manifestations for diagnosis, medical and developmental implications, and possible pathogenesis. Copyright Wiley-Liss. Inc.

Frequent callers present a challenge for crisis helplines, which strive to achieve optimal outcomes for all callers within finite resources. This study aimed to describe frequent callers to Lifeline (the largest crisis helpline in Australia) and compare them with non-frequent callers, with a view to furthering knowledge about models of service delivery that might meet the needs of frequent callers. Lifeline provided an anonymous dataset on calls made between December 2011 and May 2013. We assumed calls from the same (encrypted) phone number were made by the same person, and aggregated call level data up to the person level. Individuals who made 0.667 calls per day in any period from 1 week to the full 549 days for which we had data (i.e. 4.7 calls in 7 days, 20 calls in 30 days, 40 calls in 60 days, etc.) were regarded as frequent callers. Our analysis dataset included 411,725 calls made by 98,174 individuals, 2594 (2.6%) of whom met our definition of frequent callers. We identified a number of predictors of being a frequent caller, including being male or transgender, and never having been married. The odds increased with age until 55-64 years, and then declined. Suicidality, self-harm, mental health issues, crime, child protection and domestic violence issues all predicted being a frequent caller. Collectively, frequent callers have a significant impact on crisis lines, and solutions need to be found for responding to them that are in everybody's best interests (i.e. the frequent callers themselves, other callers, telephone crisis supporters who staff crisis lines, and those who manage crisis lines). In striking this balance, the complex and multiple needs of frequent callers must be taken into account. © The Royal Australian and New Zealand College of Psychiatrists 2014.

Sonography-guided hydrostatic reduction of ileocolic intussusception in children: analysis of failure and success in consecutive patients presenting timely to the hospital.

Menke, Jan; Kahl, Fritz

2015-03-01

In children with ileocolic intussusception sonography is increasingly being used for diagnosis, whereas fluoroscopy is frequently used for guiding non-invasive reduction. This study assessed the success rate of radiation-free sonography-guided hydrostatic reduction in children with ileocolic intussusception, using novel well-defined success rate indices. All children were evaluated who presented from 2005 to 2013 to the local university hospital with ileocolic intussusception. The patients were treated with sonography-guided hydrostatic reduction unless primary surgery was clinically indicated. The according success rate was determined by indices of Bekdash et al. They represent the ratio of persistently successful non-surgical reductions versus four different denominators, depending on including/excluding cases with primary surgery and including/excluding cases requiring bowel resection/intervention. Fifty-six consecutive patients were included (age, 3 months to 7.8 years). About 80% of the patients presented until 24 h and 20% until 48 h after the onset of symptoms. Seven patients underwent primary surgery, with bowel resection required in three cases. Hydrostatic reduction was attempted in 49 patients, being permanently successful in 41 cases (selective reduction rate 41/49 = 83.7%; crude reduction rate 41/56 = 73.2%). The remaining eight patients underwent secondary surgery, with just two patients not requiring surgical bowel resection/intervention (corrected selective reduction rate 41/43 = 95.3%). The composite reduction rate was 87.2% (successful/feasible reductions, 41/47). Radiation-free sonography-guided hydrostatic reduction has a good success rate in children with ileocolic intussusception. It may be particularly valuable in centers that are already experienced with using sonography for the diagnosis.

Full Text Available BACKGROUNDS: With 10% of the general population aged 15-59 years chronically infected with hepatitis C virus (HCV, Egypt is the country with the highest HCV prevalence worldwide. Healthcare workers (HCWs are therefore at particularly high risk of HCV infection. Our aim was to study HCV infection risk after occupational blood exposure among HCWs in Cairo. METHODOLOGY/PRINCIPAL FINDINGS: The study was conducted in 2008-2010 at Ain Shams University Hospital, Cairo. HCWs reporting an occupational blood exposure at screening, having neither anti-HCV antibodies (anti-HCV nor HCV RNA, and exposed to a HCV RNA positive patient, were enrolled in a 6-month prospective cohort with follow-up visits at weeks 2, 4, 8, 12 and 24. During follow-up, anti-HCV, HCV RNA and ALT were tested. Among 597 HCWs who reported a blood exposure, anti-HCV prevalence at screening was 7.2%, not different from that of the general population of Cairo after age-standardization (11.6% and 10.4% respectively, p = 0.62. The proportion of HCV viremia among index patients was 37%. Of 73 HCWs exposed to HCV RNA from index patients, nine (12.3%; 95%CI, 5.8-22.1% presented transient viremia, the majority of which occurred within the first two weeks after exposure. None of the workers presented seroconversion or elevation of ALT. CONCLUSIONS/SIGNIFICANCE: HCWs of a general University hospital in Cairo were exposed to a highly viremic patient population. They experienced frequent occupational blood exposures, particularly in early stages of training. These exposures resulted in transient viremic episodes without established infection. These findings call for further investigation of potential immune protection against HCV persistence in this high risk group.

Frequent demands from others in relationships are associated with worse physiological and health outcomes. The present research investigated 2 potential moderators of the relationship between frequency of demands from one's family and inflammatory profiles among adolescents: (a) closeness of adolescents' relationships with their families, and (b) the frequency with which adolescents provided help to their families. Two hundred thirty-four adolescents, ages 13-16 (Mage = 14.53; 47.83% male), completed a daily dairy in which they reported on the frequency of demands made by family members. They were also interviewed about the closeness of their family relationships and reported in the daily diary on how frequently they provided help to their families. Adolescents also underwent a blood draw to assess low-grade inflammation and proinflammatory cytokine production in response to bacterial stimulation. More frequent demands from family predicted higher levels of low-grade inflammation and cytokine production in response to bacterial stimulation in adolescents. Family closeness moderated the relationship between frequent demands and stimulated cytokine production such that more frequent demands predicted higher cytokine production among adolescents who were closer to their families. Furthermore, frequency of providing help moderated the relationship between frequent demands and both low-grade inflammation and stimulated cytokine production, such that more frequent demands predicted worse inflammatory profiles among adolescents who provided more help to their families. These findings build on previous work on family demands and health to show under what circumstances family demands might have a physiological cost.

2004-01-01

Objective: Though a number of studies have attempted to list the risk factors for DVT, there seems to be paucity of information relating to patients in Africa. We realized that a number of patients referred to our department for venoscintigraphy have concomitant tuberculosis and retroviral disease. Therefore, we decided to assess the possible relationship between DVT and the above-mentioned concomitant diseases. Method: A retrospective study of all patients referred for venous scintigraphy of the lower limbs in 2003 was done. Data from 160 patients was available for analysis. We looked at patient age and gender as well as the incidence of concurrent tuberculosis and retro-viral disease. The results are presented in a table. The remaining patients have shown either chronic venous disease or equivocal results. Conclusion: Tuberculosis and retroviral disease may be contributing risk factors in our population. (author)

Objective: To determine the most common clinical presentation and causative microorganism for acute appendicitis. Study Design: Descriptive. Place and duration of study: Department of Surgery, Combined Military Hospital Multan, from June 2002 to May 2004. Patients and Methods: Clinical features of all the patients, older than 5 years of age diagnosed with acute appendicitis were recorded. Patients presented with other pathology which mimic acute appendicitis were excluded from the study. Surgery was done under general anaesthesia. Appendices of all the patient as well as pus swabs from abdominal cavity were sent to the laboratory for histopathology and microbiological cultures to confirm the diagnoses of acute appendicitis and causative organism. Results: The mean age of 75 subjects was 32.56 +- 11.93 years. The most common symptom was pain in right iliac fossa (80 % cases) and the most common physical sign was tenderness (92% cases). Some of the patients(9.3%) had a histologically normal appendix. Maximum isolates on culture were E. coli. Conclusion: The most common presentation of acute appendicitis was pain in right iliac fossa while the most sensitive sign was tenderness. Proper history and sharp clinical examination is the key to diagnosis. The most frequent organism of appendicitis was Escherichia Coli. (author)

An Easily Overlooked Presentation of Malignant Psoas Abscess: Hip Pain

Directory of Open Access Journals (Sweden)

Ayhan Askin

2015-01-01

Full Text Available Psoas abscess is a rare infectious disease with nonspecific clinical presentation that frequently causes a diagnostic difficulty. Its insidious onset and occult characteristics can cause diagnostic delays. It is classified as primary or secondary. Staphylococcus aureus is the most commonly causative pathogen in primary psoas abscess. Secondary psoas abscess usually occurs as a result of underlying diseases. A high index of clinical suspicion, the past and recent history of the patient, and imaging studies can be helpful in diagnosing the disease. The delay of the treatment is related with high morbidity and mortality rates. In this paper, 54-year-old patient with severe hip pain having an abscess in the psoas muscle due to metastatic cervical carcinoma is presented.

This study presents the results of experimental evaluations of an ontology-based frequently asked question retrieval system in the domain of HIV and AIDS. The main purpose of the system is to provide answers to questions on HIV/AIDS using ontology. To evaluate the effectiveness of the frequently asked question retrieval system, we conducted two experiments. The first experiment focused on the evaluation of the quality of the ontology we developed using the OQuaRE evaluation framework which is based on software quality metrics and metrics designed for ontology quality evaluation. The second experiment focused on evaluating the effectiveness of the ontology in retrieving relevant answers. For this we used an open-source information retrieval platform, Terrier, with retrieval models BM25 and PL2. For the measurement of performance, we used the measures mean average precision, mean reciprocal rank, and precision at 5. The results suggest that frequently asked question retrieval with ontology is more effective than frequently asked question retrieval without ontology in the domain of HIV/AIDS.

BACKGROUND Splenic injury is the leading cause of major bleeding after blunt abdominal trauma. We examined the clinical and radiological presentations, management, and outcome of blunt splenic injuries (BSI) in our institution. MATERIAL AND METHODS A retrospective study of BSI patients between 2011 and 2014 was conducted. We analyzed and compared management and outcome of different splenic injury grades in trauma patients. RESULTS A total of 191 BSI patients were identified with a mean (SD) age of 26.9 years (13.1); 164 (85.9%) were males. Traffic-related accident was the main mechanism of injury. Splenic contusion and hematoma (77.2%) was the most frequent finding on initial computerized tomography (CT) scans, followed by shattered spleen (11.1%), blush (11.1%), and devascularization (0.6%). Repeated CT scan revealed 3 patients with pseudoaneurysm who underwent angioembolization. Nearly a quarter of patients were managed surgically. Non-operative management failed in 1 patient who underwent splenectomy. Patients with grade V injury presented with higher mean ISS and abdominal AIS, required frequent blood transfusion, and were more likely to be FAST-positive (p=0.001). The majority of low-grade (I-III) splenic injuries were treated conservatively, while patients with high-grade (IV and V) BSI frequently required splenectomy (p=0.001). Adults were more likely to have grade I, II, and V BSI, blood transfusion, and prolonged ICU stay as compared to pediatric BSI patients. The overall mortality rate was 7.9%, which is mainly association with traumatic brain injury and hemorrhagic shock; half of the deaths occurred within the first day after injury. CONCLUSIONS Most BSI patients had grade I-III injuries that were successfully treated non-operatively, with a low failure rate. The severity of injury and presence of associated lesions should be carefully considered in developing the management plan. Thorough clinical assessment and CT scan evaluation are crucial for

Legionella pneumophila infection presenting as headache, confusion and dysarthria in a human immunodeficiency virus-1 (HIV-1 positive patient: case report

Full Text Available Abstract Background Legionella pneumophila is a common cause of community-acquired pneumonia. Central nervous system dysfunction is common, and diagnosis in the absence of pulmonary symptoms can be challenging. Here we describe an atypical clinical presentation of Legionella infection in a patient with HIV who was found to have an unusual neuroradiologic lesion that further served to obscure the diagnosis. This is the first such description in a patient with Legionellosis and HIV coinfection. Case presentation A 43 year-old HIV positive man presented to our hospital with dysarthria, fevers, headache, and altered mental status. Initial work-up revealed pneumonia and a lesion of the splenium of the corpus callosum on magnetic resonance imaging. He was subsequently diagnosed with Legionella pneumonia and treated with complete symptom resolution. Conclusions Neurologic abnormalities are frequent in Legionellosis, but the diagnosis may be difficult in the absence of overt respiratory symptoms and in the presence of HIV coinfection. A high index of suspicion and early initiation of empiric antibiotics is imperative since early treatment may help prevent long-term sequelae. Neuroimaging abnormalities, though rare, can help the physician narrow down the diagnosis and avoid unnecessary invasive testing. Future studies should aim to elucidate the as yet unknown role of neuroimaging in the diagnoses and prognostication of Legionellosis, as well as the interaction between Legionella infection and HIV.

Fear of falling and quality of life scores were assessed at baseline and 12-month periods.Results: 146 subjects were recruited, 116 female (79.5% with a mean age of 67.1 years. At the end of the study, 49% of participants had not fallen. All of the balancing abilities were compared between frequent and infrequent fallers and were significantly improved (P < 0.001 except for functional reach in the frequent fall group. Most subjects (72%–79% complied well with the exercise program. However, compliance had no effect on balancing abilities. About 36.4% of participants had adverse events from exercise, of which knee pain was the top ranked. The quality of life and the fall efficacy scores increased significantly at the end of the study. Factors affecting falling were compliance with exercise (adjusted odds ratio [OR]: 2.55, 95% confidence intervals [CI]: 1.04, 6.30 and a history of falling ≥3 times in the previous year (adjusted OR: 3.76, 95% CI: 1.18, 11.98.Conclusion: Performing simply-designed balancing exercises, at least 3 days per week, can increase

Carney complex (CNC) is an autosomal dominant multiple neoplasia, caused mostly by inactivating mutations of the regulatory subunit 1A of the protein kinase A (PRKAR1A). Primary pigmented nodular adrenocortical disease (PPNAD) is the most frequent endocrine manifestation of CNC with a great inter-individual variability. Germline, protein-truncating mutations of phosphodiesterase type 11A (PDE11A) have been described to predispose to a variety of endocrine tumors, including adrenal and testicular tumors. Our objective was to investigate the role of PDE11A as a possible gene modifier of the phenotype in a series of 150 patients with CNC. A higher frequency of PDE11A variants in patients with CNC compared with healthy controls was found (25.3 vs. 6.8%, P CNC patients, those with PPNAD were significantly more frequently carriers of PDE11A variants compared with patients without PPNAD (30.8 vs. 13%, P = 0.025). Furthermore, men with PPNAD were significantly more frequently carriers of PDE11A sequence variants (40.7%) than women with PPNAD (27.3%) (P CNC patients, a high frequency of PDE11A variants, suggesting that PDE11A is a genetic modifying factor for the development of testicular and adrenal tumors in patients with germline PRKAR1A mutation.

Graph mining is a well-explored area of research which is gaining popularity in the data mining community. A graph is a general model to represent data and has been used in many domains such as cheminformatics, web information management system, computer network, and bioinformatics, to name a few. In graph mining the frequent subgraph discovery is a challenging task. Frequent subgraph mining is concerned with discovery of those subgraphs from graph dataset which have frequent or multiple instances within the given graph dataset. In the literature a large number of frequent subgraph mining algorithms have been proposed; these included FSG, AGM, gSpan, CloseGraph, SPIN, Gaston, and Mofa. The objective of this research work is to perform quantitative comparison of the above listed techniques. The performances of these techniques have been evaluated through a number of experiments based on three different state-of-the-art graph datasets. This novel work will provide base for anyone who is working to design a new frequent subgraph discovery technique.

This study reviews the presenting symptoms of colorectal cancer in the ethnically diverse Middlemore Hospital referral population of South Auckland, New Zealand. The performance of the newly introduced Auckland Regional Grading Criteria as prediction tool for selecting colorectal cancer cases referred from primary care was evaluated in this group. Retrospective review of all colorectal cancer (CRC) cases diagnosed between January 2006 and January 2011. Information extracted from case note review was used to grade patients using the Auckland Regional Grading Criteria. A total of 799 patients were included. The commonest symptoms were: rectal bleeding (25.5-42.3%) and change in bowel habit (20.6-26.8%). Low-risk symptoms including abdominal pain (16.3-46.8%) and weight loss (18.4-26.1%) were not uncommon. 64.4% of Maori and 64.9% of Pacific patients had stage III or IV cancers. Pacific patients had more stage IV disease, 37.7% (pAuckland Regional Grading Criteria would miss 24.7% of the patients with CRC in the referral population. While rectal bleeding and change in bowel habit are frequent presenting symptoms, low-risk atypical symptoms including constipation, weight loss and abdominal pain were not uncommon. Significant proportion of Pacific patients present with late-stage disease. The current Auckland Regional grading criteria would miss significant proportion of our study population with colorectal cancer.

To describe the clinical manifestations, cerebrospinal fluid (CSF) characteristics, imaging studies and prognostic factors of adverse clinical outcomes (ACO) among adults with herpes simplex virus (HSV) or varicella zoster virus (VZV) CNS infections. Retrospective review of adult patients with positive HSV or VZV polymerase chain reaction on CSF from an observational study of meningitis or encephalitis in Houston, TX (2004-2014), and New Orleans, LA (1999-2008). Ninety-eight adults patients were identified; 25 had encephalitis [20 (20.4 %) HSV, 5 (5.1 %) VZV], and 73 had meningitis [60 (61.1 %) HSV and 13 (13.3 %) VZV]. HSV and VZV had similar presentations except for nausea (P 1 and an encephalitis presentation were independently associated with an ACO. The treatment for HSV meningitis was variable, and all patients had a good clinical outcome. Alpha herpes CNS infections due to HSV and VZV infections have similar clinical and laboratory manifestations. ACO was observed more frequently in those patients with comorbidities and an encephalitis presentation.

Diencephalic syndrome is an uncommon cause of failure to thrive in early childhood that is associated with central nervous system neoplasms in the hypothalamic-optic chiasmatic region. It is characterized by complex signs and symptoms related to hypothalamic dysfunction; such nonspecific clinical features may delay diagnosis of the brain tumor. In this study, we analyzed a series of cases in order to define characteristic features of diencephalic syndrome. We performed a retrospective study of 8 patients with diencephalic syndrome (age, 5-38 months). All cases had presented to Seoul National University Children's Hospital between 1995 and 2013, with the chief complaint of poor weight gain. Diencephalic syndrome with central nervous system (CNS) neoplasm was identified in 8 patients. The mean age at which symptoms were noted was 18±10.5 months, and diagnosis after symptom onset was made at the mean age of 11±9.7 months. The mean z score was -3.15±1.14 for weight, -0.12±1.05 for height, 1.01±1.58 for head circumference, and -1.76±1.97 for weight-for-height. Clinical features included failure to thrive (n=8), hydrocephalus (n=5), recurrent vomiting (n=5), strabismus (n=2), developmental delay (n=2), hyperactivity (n=1), nystagmus (n=1), and diarrhea (n=1). On follow-up evaluation, 3 patients showed improvement and remained in stable remission, 2 patients were still receiving chemotherapy, and 3 patients were discharged for palliative care. Diencephalic syndrome is a rare cause of failure to thrive, and diagnosis is frequently delayed. Thus, it is important to consider the possibility of a CNS neoplasm as a cause of failure to thrive and to ensure early diagnosis.

Although mutation of APC or CTNNB1 (β-catenin) is rare in breast cancer, activation of Wnt signalling is nonetheless thought to play an important role in breast tumorigenesis, and epigenetic silencing of Wnt antagonist genes, including the secreted frizzled-related protein (SFRP) and Dickkopf (DKK) families, has been observed in various tumours. In breast cancer, frequent methylation and silencing of SFRP1 was recently documented; however, altered expression of other Wnt antagonist genes is largely unknown. In the present study, we found frequent methylation of SFRP family genes in breast cancer cell lines (SFRP1, 7 out of 11, 64%; SFRP2, 11 out of 11, 100%; SFRP5, 10 out of 11, 91%) and primary breast tumours (SFRP1, 31 out of 78, 40%; SFRP2, 60 out of 78, 77%; SFRP5, 55 out of 78, 71%). We also observed methylation of DKK1, although less frequently, in cell lines (3 out of 11, 27%) and primary tumours (15 out of 78, 19%). Breast cancer cell lines express various Wnt ligands, and overexpression of SFRPs inhibited cancer cell growth. In addition, overexpression of a β-catenin mutant and depletion of SFRP1 using small interfering RNA synergistically upregulated transcriptional activity of T-cell factor/lymphocyte enhancer factor. Our results confirm the frequent methylation and silencing of Wnt antagonist genes in breast cancer, and suggest that their loss of function contributes to activation of Wnt signalling in breast carcinogenesis.

Dust storms in northern China strongly affect the living and health of people there and the dusts could travel a full circle of the globe in a short time. Historically, more frequent dust storms occurred during cool periods, particularly the Little Ice Age (LIA), generally attributed to the strengthened Siberian High. However, limited by chronological uncertainties in proxy records, this mechanism may not fully reveal the causes of dust storm frequency changes. Here we present a late Holocene dust record from the Qaidam Basin, where hydrological changes were previously reconstructed, and examine dust records from northern China, including the ones from historical documents. The records, being broadly consistent, indicate the onset of frequent dust storms at ~AD 1100. Further, peaked dust storm events occurred at episodes of high total solar irradiance or warm-dry conditions in source regions, superimposed on the high background of frequent dust storms within the cool LIA period. We thus suggest that besides strong wind activities, the centennial-scale dust storm events over the last 1000 years appear to be linked to the increased availability of dust source. With the anticipated global warming and deteriorating vegetation coverage, frequent occurrence of dust storms in northern China would be expected to persist.

XML data is widely used in the information exchange field of Internet, and XML document data clustering is the hot research topic. In the XML document clustering process, measure differences between two XML documents is time costly, and impact the efficiency of XML document clustering. This paper proposed an XML documents clustering method based on frequent patterns of XML document dataset, first proposed a coding tree structure for encoding the XML document, and translate frequent pattern mining from XML documents into frequent pattern mining from string. Further, using the cosine similarity calculation method and cohesive hierarchical clustering method for XML document dataset by frequent patterns. Because of frequent patterns are subsets of the original XML document data, so the time consumption of XML document similarity measure is reduced. The experiment runs on synthetic dataset and the real datasets, the experimental result shows that our method is efficient.

Abnormalities of the upper esophageal sphincter (UES) on high-resolution esophageal manometry (HREM) have been observed in both symptomatic and asymptomatic individuals and are often interpreted as incidental findings of unclear clinical significance. Our primary aims were: (1) to assess the frequency of UES abnormalities in consecutive patients referred for HREM studies; and (2) to characterize the demographics, clinical symptoms, and manometric profiles associated with UES abnormalities as compared with those with normal UES function. We performed a retrospective study of 200 consecutive patients referred for HREM. Patients were divided into those with normal and abnormal UES function, including impaired relaxation (residual pressure >12 mm Hg), hypertensive (>104 mm Hg), and hypotensive (achalasia were significantly more likely to have UES abnormalities as compared with normal UES function (57.2% vs. 42.9%, P=0.04), with the most frequent abnormality being a hypertensive UES (50%). In addition, patients with impaired lower esophageal sphincter (LES) relaxation (esophagogastric junction outflow obstruction or achalasia) were more likely to have an UES abnormality present as compared with those with normal LES relaxation (53.1% vs. 28.6%, P=0.01). When we assessed for treatment response among patients with achalasia, we found that subjects with evidence of UES dysfunction had significantly worse treatment outcomes as compared with those without UES abnormalities present (20% improved vs. 100%, P=0.015). This remained true even after adjusting for type of treatment received (surgical myotomy, per-oral endoscopic mytotomy, botulinum toxin injection, pneumatic dilatation, medical therapy, P=0.67) and achalasia subtype (P=1.00). UES abnormalities are a frequent finding on HREM studies, especially in patients with impaired LES relaxation, including both achalasia and esophagogastric junction outflow obstruction. Interestingly, the most common UES abnormality associated

Acute kidney injury (AKI) is a frequent and significant complication of cancer and cancer therapy. Cancer patients frequently encounter risk factors for AKI including older age, CKD, prerenal conditions, sepsis, exposure to nephrotoxins, and obstructive physiology. AKI can also be secondary to paraneoplastic conditions, including glomerulonephritis and microangiopathic processes. This complication can have significant consequences, including effects on patients' ability to continue to receive therapy for their malignancy. This review will serve to summarize potential etiologies of AKI that present in patients with cancer as well as to highlight specific patient populations, such as the critically ill cancer patient.

Full Text Available Background. Chronic pain (CP accounts for 10–16% of emergency department (ED visits, contributing to ED overcrowding and leading to adverse events. Objectives. To describe patients with CP attending the ED and identify factors contributing to their visit. Methods. We used a mixed-method design combining interviews and questionnaires addressing pain, psychological distress, signs of opioid misuse, and disability. Participants were adults who attended the EDs of a large academic tertiary care center for their CP problem. Results. Fifty-eight patients (66% women; mean age 46.5, SD = 16.9 completed the study. The most frequently cited reason (60% for ED visits was inability to cope with pain. Mental health problems were common, including depression (61% and anxiety (45%. Participants had questions about the etiology of their pain, concerns about severe pain-related impairment, and problems with medication renewals or efficacy and sometimes felt invalidated in the ED. Although most participants had a primary care physician, the ED was seen as the only or best option when pain became unmanageable. Conclusions. Patients with CP visiting the ED often present with complex difficulties that cannot be addressed in the ED. Better access to interdisciplinary pain treatment is needed to reduce the burden of CP on the ED.

Full Text Available Introduction: Dengue haemorrhagic fever is known for its haemorrhagic and neurologic complications. Neurologic complications are caused by three mechanism namely neurotropism, systemic complications causing encephalopathy and postinfectious immune-mediated mechanisms. However acute compressive neuropathy due to haemorrhage is not frequent and we could find no literature describing this Case Report: We report a case of acute compressive ulnar neuropathy due to peri neural hematoma, following an attempt at intravenous cannulation in the cubital fossa in a patient of dengue haemorrhagic fever with thrombocytopenia. Immediate fasciotomy and removal of haematoma was performed to relieve the symptoms. Conclusion: Compression neuropathies can be seen in dengue hemorrhagic fever and removal of compressing hematoma relieves symptoms. Keywords: Dengue haemmorrhagic fever; coagulopathy; peri neural haematoma.

To present a series of infantile patients with aqueductal stenosis associated with neurofibromatosis type 1 (NF1). Nineteen patients with ages below 16 years, 11 girls and 8 boys, with NF1 presented hydrocephalus due to aqueductal stenosis. All patients, except one who died before the imaging study was performed and was diagnosed by autopsy, were studied by pneumoencephalography (since 1965 to 1974), computerized tomography (CT) (since 1975 to 1984), magnetic resonance (MR) or MR and CT (since 1985 to 2004) (two children had been studied by pneumoencephalography some years before) most times to discard optic pathway tumor and, in few patients, because of intracranial hypertension. All patients showed three ventricular hydrocephalus with aqueductal stenosis. Eleven patients showed optic pathway tumor. One patient had a benign aqueductal tumor that impaired the normal flow of cerebrospinal fluid. Neurological features of hydrocephalus occurred very rapidly in some patients and after several years of evolution in others. Two boys showed precocious puberty. All patients were treated with shunt. In our series, aqueductal stenosis occurred in about 5% of children with NF1. Aqueductal stenosis and hydrocephalus were identified at a short age because many patients were studied suspecting optic pathway tumor. Eleven patients (about 60%) associated optic pathway tumor and aqueductal stenosis.

Full Text Available CTLA-4 can regulate and maintain self-telerance, providing a negative signal limiting immunoresponses. Acute lymphoblastic leukemia is a clonal disorder of lymphoid progenitors representing the most frequent malignancy of childhood. Here, we show the presence of significantly elevated levels of a soluble form of CTLA-4 in 70% of B-ALL patients. A possible role of this soluble molecule in the pathogenesis of this neoplastic disease can be envisaged.

We have identified a class of molecules, known as 2-aminothiazoles (2-ATs), as frequent-hitting fragments in biophysical binding assays. This was exemplified by 4-phenylthiazol-2-amine being identified as a hit in 14/14 screens against a diverse range of protein targets, suggesting that this scaffold is a poor starting point for fragment-based drug discovery. This prompted us to analyze this scaffold in the context of an academic fragment library used for fragment-based drug discovery (FBDD) and two larger compound libraries used for high-throughput screening (HTS). This analysis revealed that such "promiscuous 2-aminothiazoles" (PrATs) behaved as frequent hitters under both FBDD and HTS settings, although the problem was more pronounced in the fragment-based studies. As 2-ATs are present in known drugs, they cannot necessarily be deemed undesirable, but the combination of their promiscuity and difficulties associated with optimizing them into a lead compound makes them, in our opinion, poor scaffolds for fragment libraries.

Full Text Available Abstract Background Cardiac asthma is common, but has been poorly investigated. The objective was to compare the characteristics and outcome of cardiac asthma with that of classical congestive heart failure (CHF in elderly patients. Methods Prospective study in an 1,800-bed teaching hospital. Results Two hundred and twelve consecutive patients aged ≥ 65 years presenting with dyspnea due to CHF (mean age of 82 ± 8 years were included. Findings of cardiac echocardiography and natriuretic peptides levels were used to confirm CHF. Cardiac asthma patients were defined as a patient with CHF and wheezing reported by attending physician upon admission to the emergency department. The CHF group (n = 137 and the cardiac asthma group (n = 75, differed for tobacco use (34% vs. 59%, p 2 (47 ± 15 vs. 41 ± 11 mmHg, p Conclusion Patients with cardiac asthma represented one third of CHF in elderly patients. They were more hypercapnic and experienced more distal airway obstruction. However, outcomes were similar.

Full Text Available Given that Churg-Strauss syndrome is a systemic small-vessel vasculitis, it is not usually considered in patients who present with massive hemoptysis, which is typically caused by bronchiectasis, cancer or, in some cases, aberrant bronchial arteries. This article, however, describes a novel case involving a 50-year-old Churg-Strauss patient who presented with sudden-onset massive hemoptysis. Details of the physical examination, laboratory investigations and several imaging studies, including computed tomography, bronchoscopy and three-dimensional imaging, are presented.

2009-01-01

Objective: The present study was aimed at describing uncommon presentations of intraosseous hemophilic pseudotumor in imaging diagnosis. Materials and methods: Retrospective study evaluating five hemophilic pseudotumors in bones of two patients with hemophilia A. Imaging findings were consensually evaluated by two musculoskeletal radiologists. Plain radiography, computed tomography and magnetic resonance imaging studies were analyzed. Results: At contrast-enhanced computed tomography images, one of the lesions on the left thigh was visualized with heterogeneously enhanced solid areas. This finding was later confirmed by anatomopathological study. Another uncommon finding was the identification of a healthy bone portion interposed between two intraosseous pseudotumors in the humerus. And, finally, a femoral pseudotumor with extension towards soft tissues and transarticular extension, and consequential tibial and patellar involvement. Conclusion: The above described imaging findings are not frequently reported in cases of intraosseous pseudotumors in hemophilic patients. It is important that radiologists be aware of these more uncommon presentations of intraosseous pseudotumors. (author)

Works cited in six forensic psychology journals published 2008-2010 were counted to identify the most frequently cited journals. The sample of works cited (N = 21,776) was not a definitive ranked list of important journals in forensic psychology, but was large enough to indicate high-impact journals. The list of frequently cited publications included more general psychiatry and psychology journals than titles specific to forensic psychology. The implications of the proportion of general versus specific titles for collections supporting research in forensic psychology were discussed.

Zun, Leslie S; Downey, La Vonne A

2008-01-01

The primary purpose of this study was to determine the level of agitation that psychiatric patients exhibit upon arrival to the emergency department. The secondary purpose was to determine whether the level of agitation changed over time depending upon whether the patient was restrained or unrestrained. An observational study enrolling a convenience sample of 100 patients presenting with a psychiatric complaint was planned, in order to obtain 50 chemically and/or physically restrained and 50 unrestrained patients. The study was performed in summer 2004 in a community, inner-city, level 1 emergency department with 45,000 visits per year. The level of patient agitation was measured using the Agitated Behavior Scale (ABS) and the Richmond Agitation-Sedation Scale (RASS) upon arrival and every 30 minutes over a 3-hour period. The inclusion criteria allowed entry of any patient who presented to the emergency department with a psychiatric complaint thought to be unrelated to physical illness. Patients who were restrained for nonbehavioral reasons or were medically unstable were excluded. 101 patients were enrolled in the study. Of that total, 53 patients were not restrained, 47 patients were restrained, and 1 had incomplete data. There were no differences in gender, race, or age between the 2 groups. Upon arrival, 2 of the 47 restrained patients were rated severely agitated on the ABS, and 13 of 47 restrained patients were rated combative on the RASS. There was a statistical difference (p = .01) between the groups on both scales from time 0 to time 90 minutes. Scores on the agitation scales decreased over time in both groups. One patient in the unrestrained group became unarousable during treatment. This study demonstrated that patients who were restrained were more agitated than those who were not, and that agitation levels in both groups decreased over time. Some restrained patients did not meet combativeness or severe agitation criteria, suggesting either that use of

Churg–Strauss Syndrome Presenting with Endobronchial Masses

Directory of Open Access Journals (Sweden)

Veli Çetinsu

2015-12-01

Full Text Available Churg–Strauss syndrome is a condition with unknown etiology and asthma, allergic rhinitis, eosinophilic infiltration of blood and tissues, and transient infiltration of the lungs. It occurs mostly in the 3rd–4th decades of life with an incidence of 2.4/1000000. Presentation frequently involves nodular lung infiltrations, infiltrations with cavity, ground-glass appearance, and alveolar opacity. However, endobronchial mass is an unexpected presentation. In the current case report, we present a 45-year-old male patient who was receiving asthma therapy for 5 years. In the last follow-up visit, we identified a mass in the right hilum on X-ray radiography and performed fiberoptic bronchoscopy. Pathologic examination of biopsy material verified the diagnosis of Churg–Strauss syndrome. Bronchial mass is an unexpected presentation of Churg–Strauss syndrome and pathologic examination is essential to distinguish it from pulmonary malignancies

To evaluate occurrence of cerebellar stroke in Emergency Department (ED) presentations of isolated dizziness (dizziness with a normal exam and negative neurological review of systems). A 5-year retrospective study of ED patients presenting with a chief complaint of "dizziness or vertigo", without other symptoms or signs in narrative history or on exam to suggest a central nervous system lesion, and work-up included a brain MRI within 48h. Patients with symptoms commonly peripheral in etiology (nystagmus, tinnitus, gait instability, etc.) were included in the study. Patient demographics, stroke risk factors, and gait assessments were recorded. One hundred and thirty-six patients, who had a brain MRI for isolated dizziness, were included. There was a low correlation of gait assessment between ED physician and Neurologist (49 patients, Spearman's correlation r 2 =0.17). Based on MRI DWI sequence, 3.7% (5/136 patients) had acute cerebellar strokes, limited to or including, the medial posterior inferior cerebellar artery vascular territory. In the 5 cerebellar stroke patients, mean age, body mass index (BMI), hemoglobin A1c, gender distribution, and prevalence of hypertension were similar to the non-cerebellar stroke patient group. Mean LDL/HDL ratio was 3.63±0.80 and smoking prevalence was 80% in the cerebellar stroke group compared to 2.43±0.79 and 22% (respectively, p valuesstroke group. Though there was preselection bias for stroke risk factors, our study suggests an important proportion of cerebellar stroke among ED patients with isolated dizziness, considering how common this complaint is.

Full Text Available "nTuberculosis (TB still represents a major public health problem worldwide. The primary form of disease is most often localized to the lung. In a minority of patients, progressive pulmonary disease spreads to other organ systems through self inoculation via infected sputum, blood and lymphatic system, establishing the secondary form of tuberculosis. We present a patient that was referred to us with complaint of ulcerative mouth lesions from 3 months ago. In physical examination multiple erythematous and irregularly ulcerative lesions affecting soft palate area, uvula and anterior tonsillar pillar was noted bilaterally. Punch biopsy was done from several points that revealed chronic granulomatous inflammation. Ziehl-Nielsen staining of cultured specimen demonstrated acid-fast bacilli. Chest X-ray showed apical pulmonary involvement, suggesting tuberculosis infection. Patient was treated with anti-tuberculosis 4 drugs regimen. In the one year follow-up period after complete treatment; patient didn't have any evidence of disease. Oral and oropharyngeal TB lesions are uncommon, it is estimated that only 0.05-5% of total TB cases may present with oral manifestations, but should be an important consideration in the differential diagnosis of lesions that appear in the oral cavity and oropharynx. The secondary form is more frequent and involves mainly the tongue but involvement of pharynx is quite rare condition. Although tuberculosis of oropharynx is relatively rare, with the increasing incidence of tuberculosis, it must be considered in the differential diagnosis of atypical ulcerative lesions of the mouth and oropharynx.

We describe a patient with seizures arising from right anterior-inferior frontal lobe presenting as myoclonic epilepsy. A 19-year-old man had experienced frequent paroxysmal bilateral myoclonic jerks involving his upper arms, shoulders, neck, and upper trunk since the age of 10. His baseline EEG showed intermittent right frontal spikes, and his ictal EEG showed rhythmic sharp theta discharges in the same area. MRI revealed cortical dysplasia in the right inferior frontal gyrus, and ictal-interictal SPECT analysis by SPM showed increased signal abnormality in this region. Diffusion tensor imaging (DTI) showed defects in fasciculi in the same area. These findings suggest that frontal lobe epilepsy should be considered in some patients with myoclonic seizures.

2017-09-01

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

Full Text Available Fibromyalgia Syndrome (FMS is a condition considered to represent a prototype of central sensitization syndrome, characterized by chronic widespread pain and along with symptoms of fatigue, non-restorative sleep and cognitive difficulties. FMS can be induced by trauma, infection or emotional stress with cumulative evidence that dissociation is relatively frequent in FMS patients. Two randomized controlled trials have shown that hyperbaric oxygen therapy (HBOT can induce neuroplasticity and be effective in patients suffering from FMS. In this paper we present, for the first time, case series of female fibromyalgia patients who, in the course of HBOT, suddenly recalled repressed traumatic memories of childhood sexual abuse (CSA. The surfacing of the repressed (dissociative memories decades after the sexual abuse events was sudden and utterly surprising. No psychological intervention was involved. As the memories surfaced, the physical pain related to FMS subsided. In one patient who had brain single photon emission CT (SPECT before and after HBOT, the prefrontal cortex appeared suppressed before and reactivated after. The 3 cases reported in this article are representative of a total of nine fibromyalgia patients who experienced a retrieval of repressed memory during HBOT. These cases provide insights on dissociative amnesia and suggested mechanism hypothesis that is further discussed in the article. Obviously, prospective studies cannot be planned since patients are not aware of their repressed memories. However, it is very important to keep in mind the possibility of surfacing memories when treating fibromyalgia patients with HBOT or other interventions capable of awakening dormant brain regions.

Full Text Available Body dysmorphic disorder is an obsessive-compulsive related psychiatric disorder characterized by excessive preoccupation about an imagined or slight defect in appearance. Preoccupation of the appearance with the skin, hair and nose are most common. Impairment of the quality of life, comorbidity of the psychiatric and personality disorder are related with body dysmorphic disorder. Nowadays, cosmetic procedure has become increasingly popular especially among women. The prevalence of body dysmorphic disorder among patients seeking cosmetic treatment in surgery or dermatology clinics is higher than general population. As postoperatively some patients dissatisfied with the surgery, dermatologists and surgeons should be informed about body dysmorphic disorder. This aim of this review was to assess prevalance, clinical features, motivational factors of patients with body dysmorphic disorder presenting for cosmetic medical treatments.

Frequent Chromosome Aberrations Revealed by Molecular Cytogenetic Studies in Patients with Aniridia

OpenAIRE

Crolla, John A.; van Heyningen, Veronica

2002-01-01

Seventy-seven patients with aniridia, referred for cytogenetic analysis predominantly to assess Wilms tumor risk, were studied by fluorescence in situ hybridization (FISH), through use of a panel of cosmids encompassing the aniridia-associated PAX6 gene, the Wilms tumor predisposition gene WT1, and flanking markers, in distal chromosome 11p13. Thirty patients were found to be chromosomally abnormal. Cytogenetically visible interstitial deletions involving 11p13 were found in 13 patients, 11 o...

Camila de Assis Faria

Full Text Available There are numerous neuropsychological tests for assessing executive functions in aging, which vary according to the different domains assessed. OBJECTIVE: To present a systematic review of the most frequently used instruments for assessing executive functions in older adults with different educational levels in clinical and experimental research. METHODS: We searched for articles published in the last five years, using the PubMed database with the following terms: "neuropsychological tests", "executive functions", and "mild cognitive impairment". There was no language restriction. RESULTS: 25 articles fulfilled all the inclusion criteria. The seven neuropsychological tests most frequently used to evaluate executive functions in aging were: [1] Trail Making Test (TMT Form B; [2] Verbal Fluency Test (VFT - F, A and S; [3] VFT Animals category; [4] Clock Drawing Test (CDT; [5] Digits Forward and Backward subtests (WAIS-R or WAIS-III; [6] Stroop Test; and [7] Wisconsin Card Sorting Test (WCST and its variants. The domains of executive functions most frequently assessed were: mental flexibility, verbal fluency, planning, working memory, and inhibitory control. CONCLUSION: The study identified the tests and domains of executive functions most frequently used in the last five years by research groups worldwide to evaluate older adults. These results can direct future research and help build evaluation protocols for assessing executive functions, taking into account the different educational levels and socio-demographic profiles of older adults in Brazil.

The use of oral fluid for detecting drugs of abuse has become increasingly more frequent. Few studies have, however, investigated the detection times for drugs of abuse in oral fluid, compared with that of in urine or in blood. Cannabis is the world's most widely used drug of abuse, and the detection times for cannabis, in different types of matrixes, are therefore important information to the laboratories or institutions performing and evaluating drugs of abuse analyses. It is well known that frequent use of high dosages of cannabis, for longer periods of time, might lead to prolonged detection times for THC-COOH in urine. Cannabis intake is detected in oral fluid as THC, and a positive finding is considered to be a result of recent smoking, although some studies have already reported longer detection times. The aim of this study was to investigate the detection time for THC in oral fluid, collected from drug addicts admitted for detoxification. Findings in oral fluid were compared with findings in urine, among 26 patients admitted to a closed detoxification unit. The study, being the first in doing so, describes the concentration-time profiles for THC in oral fluid among chronic cannabis users, during monitored abstinence, using the Intercept collection kit. The study also includes the concentration-time profiles for creatinine-corrected THC-COOH ratios in urine samples, included to monitor for the possibility of new intakes. THC was detected in oral fluid collected from 11 of the 26 patients in the study. The elimination curves for THC in oral fluid revealed that negative samples could be interspersed among positive samples several days after cessation, whereas the THC-COOH concentrations in urine were decreasing. THC was, in this study, detected in oral fluid for up to 8 days after admission. The study shows that frequent use of high dosages of cannabis may lead to prolonged detection times, and that positive samples can be interspersed among negative samples

High idiopathic premature ventricular contractions (PVC) burden has been associated with PVC-induced cardiomyopathy. Patients may be symptomatic before left ventricular (LV) dysfunction develops. N-terminal pro-B-type natriuretic peptide (NT-proBNP) and circumferential end-systolic wall stress (cESS) on echocardiography are markers for increased ventricular wall stress. This study aimed to evaluate the relation between presenting symptoms, PVC burden, and increased ventricular wall stress in patients with frequent PVCs and preserved LV function. Eighty-three patients (41 men; 49±15 years) with idiopathic PVCs and normal LV function referred for PVC ablation were included. Type of symptoms (palpitations, fatigue, and [near-]syncope), PVC burden on 24-hour Holter, NT-proBNP levels, and cESS on echocardiography were assessed before and 3 months after ablation. Sustained successful ablation was defined as ≥80% PVC burden reduction during follow-up. Patients were symptomatic for 24 months (Q1-Q3, 16-60); 73% reported palpitations, 47% fatigue, and 30% (near-)syncope. Baseline PVC burden was 23±13%, median NT-proBNP 92 pg/mL (Q1-Q3 50-156), and cESS 143±35 kdyne/cm(2). Fatigue was associated with higher baseline NT-proBNP and cESS (PFatigue was independently associated with a significantly larger reduction in NT-proBNP. In patients with nonsuccessful ablation, NT-proBNP and cESS remained unchanged. In patients with frequent PVCs and preserved LV function, fatigue was associated with higher baseline NT-proBNP and cESS, and with a significantly larger reduction in NT-proBNP after sustained successful ablation. These findings support a link between fatigue and PVC-induced increased ventricular wall stress, despite preserved LV function. © 2015 American Heart Association, Inc.

Pancreatic and hepatic mucinous cyst neoplasms (MCNs) have a malignant potential, but indolent MCNs are not uncommon. The pathological and genetic characteristics of resected MCNs (n=15) categorized by the amount of mucin of the lining epithelium were investigated. MCNs were divided into two groups: (i) a rich (r)-MCN group (n=6), in which more than half of the epithelium was lined by abundant mucinous epithelium; and (ii) a poor (p)-MCN group (n=9), which consisted of the remaining cases. Three patients in the r-MCN group showed invasive carcinoma or high-grade dysplasia, whereas all patients in the p-MCN group showed low-grade dysplasia. Mutations of Kirsten rat sarcoma viral oncogene homolog (KRAS) were more frequent in the r-MCN group (83%) (p-MCN; 11%, p<0.05). Mucinous MCNs more frequently have KRAS mutations and higher risk of malignant progression. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

We characterized urological symptoms in a subset of patients with urological chronic pelvic pain syndrome who have a high somatic symptom burden and a wide symptom distribution fitting a polysymptomatic, polysyndromic presentation pattern. A total of 81 patients with urological chronic pelvic pain syndrome enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases MAPP Research Network Study at Washington University in St. Louis and University of Alabama at Birmingham sites. They completed a symptom questionnaire to assess the somatic symptom burden and its distribution, and GUPI (Genitourinary Pain Index) to assess urological chronic pelvic pain syndrome symptoms, impact on quality of life and self-reported treatment seeking behaviors for urological chronic pelvic pain symptoms. The polysymptomatic, polysyndromic symptom pattern was defined by self-report of numerous painful and nonpainful somatic symptoms across many organ systems and by symptom categories on the polysymptomatic, polysyndromic questionnaire. Patients with urological chronic pelvic pain syndrome and the symptom pattern reported more severe genitourinary pain on a Likert scale, more frequent pain in the last week and more widespread pain distribution in the genital and pelvic areas than patients with urological chronic pelvic pain syndrome without the pattern. Patients with the symptom pattern also had significantly higher scores on the GUPI pain subscale, quality of life subscale (worse) and total questionnaire scores than patients without the pattern. Patients with the pattern reported significantly more treatment seeking behavior than others. The polysymptomatic, polysyndromic pattern might be an important phenotypic factor to assess in the evaluation of urological chronic pelvic pain syndrome with clinical and research implications. This may be a distinct clinical subgroup among patients with urological chronic pelvic pain syndrome. Copyright © 2014 American Urological

Rett syndrome: EEG presentation.

Rett syndrome, a degenerative neurological disorder of girls, has a classical presentation and typical EEG findings. The electroencephalograms (EEGs) of 7 girls whose records have been followed from the onset of symptoms to the age of 5 or more are presented. These findings are tabulated with the Clinical Staging System of Hagberg and Witt-Engerström (1986). The records show a progressive deterioration in background rhythms in waking and sleep. The abnormalities of the background activity may only become evident at 4-5 years of age or during stage 2--the Rapid Destructive Stage. The marked contrast between waking and sleep background may not occur until stage 3--the Pseudostationary Stage. In essence EEG changes appear to lag behind clinical symptomatology by 1-3 years. An unexpected, but frequent, abnormality was central spikes seen in 5 of 7 girls. They appeared to be age related and could be evoked by tactile stimulation in 2 patients. We hypothesize that the prominent 'hand washing' mannerism may be self-stimulating and related to the appearance of central spike discharges.

Intra-articular physeal fractures of the distal femur are an uncommon injury pattern, with only a few small case series reported in the literature. To pool patients from 3 high-volume pediatric centers to better understand this injury pattern, to determine outcomes of surgical treatment, and to assess risk factors for complications. Case series; Level of evidence, 4. A multicenter retrospective review of all patients presenting with an intra-articular physeal fracture between 2006 and 2016 was performed. Patient demographic and injury data, surgical data, and postoperative outcomes were documented. Radiographs were evaluated for fracture classification (Salter-Harris), location, and displacement. Differences between patients with and without complications were compared by use of analysis of variance or chi-square tests. A total of 49 patients, with a mean age of 13.5 years (range, 7-17 years), met the inclusion criteria. The majority of fractures were Salter-Harris type III fractures (84%) involving the medial femoral condyle (88%). Football was responsible for 50% of the injuries. The initial diagnosis was missed in 39% of cases, and advanced imaging showed greater mean displacement (6 mm) compared with radiographs (3 mm). All patients underwent surgery and returned to sport with "good to excellent" results after 2 years. Complications were more common in patients with wide-open growth plates, patients with fractures involving the lateral femoral condyle, and patients who were casted ( P < .05). Clinicians evaluating skeletally immature athletes (particularly football players) with acute knee injuries should maintain a high index of suspicion for an intra-articular physeal fracture. These fractures are frequently missed, and advanced imaging may be required to establish the diagnosis. Leg-length discrepancies and angular deformities are not uncommon, and patients should be monitored closely. Surgical outcomes are good when fractures are identified, with high rates

Management of patients with inoperable, advanced lung cancer is one of the most important problems for many chest physicians, because those patients with stage 3 and stage 4 are over 70% of total patients. Although surgical treatment is attempted even in the case of stage 3 patients, many factors such as age, performance status, pulmonary and circulatory disorders accompanied with them and sometimes patient's refusal for surgical treatment preclude it. Therefore, therapeutic approach for these patients is focused on relieving their pains and troubles in their daily life. Radiation therapy is only a local treatment, but it can often control variable clinical manifestations with a highly probable estimation. Many patients can be free of disease even for a limited period. From this view-point, even at present, radiation therapy is a preferable therapeutic modality to maintain individual patient's better quality of life.

To describe the characteristics of frequent users of hospital emergency departments and analyze whether characteristics varied in relation to how revisits were distributed over the course of the year studied. Retrospective study of patients over the age of 14 years who were treated in a hospital emergency department at least 10 times in 2013. Patients were identified in 17 public hospitals in the Spanish autonomous community of Madrid. Data related to the first and successive visits were gathered and analyzed by quarter year. We included 2340 patients with a mean (SD) age of 54 (21) years. A total of 1361 (58.%) were women, 1160 (50%) had no concomitant diseases, 1366 (58.2%) were substance abusers, and 25 (1.1%) were homeless. During the first visit, 2038 (87.1%) complained of a recent health problem, and 289 (12.4%) were admitted. Sixty (2.6%) patients concentrated their revisits in a single quarters 335 (14.3%) in 2 quarters, 914 (39.1%) in 3, and 1005 (42.9%) in 4.

To review the visual status and clinical presentation of patients with retinitis pigmentosa (RP). Multicenter, retrospective, and analytical review was conducted of the visual status and clinical characteristics of patients with RP at first presentation from January 2007 to December 2011. Main outcome measure was the World Health Organization's visual status classification in relation to sex and age at presentation. Data analysis by SPSS (version 15) and statistical significance was assumed at Ppresent in their siblings 15 (71.4%), grandparents 11 (52.3%), and parents 4 (19.4%). Forty (41.7%) were blind at presentation and 23 (24%) were visually impaired. Blindness in six (15%) patients was secondary to glaucoma. Retinal vascular narrowing and retinal pigmentary changes of varying severity were present in all patients. Thirty-five (36.5%) had maculopathy, 36 (37.5%) refractive error, 19 (20%) lenticular opacities, and eleven (11.5%) had glaucoma. RP was typical in 85 patients (88.5%). Older patients had higher rates of blindness at presentation (P=0.005); blindness and visual impairment rate at presentation were higher in males than females (P=0.029). Clinical presentation with advanced diseases, higher blindness rate in older patients, sex-related difference in blindness/visual impairment rates, as well as high glaucoma blindness in RP patients requires urgent attention in southwestern Nigeria.

The objective of this study was to determine the effect of previous aerosolized pentamidine therapy on diagnosis and presentation of Pneumocystis carinii pneumonia. This was a retrospective study of fifty-two consecutive patients with P. carinii pneumonia and underlying infection with the human immunodeficiency virus (HIV) who had bronchoscopy. Twenty-one patients who were on aerosolized pentamidine therapy served as the study group. Thirty-one patients who had not received the drug served as the control group. The yield of bronchoalveolar lavage for P. carinii pneumonia was 62% for the study group and 100% for the control group (P less than 0.05). This lower yield was significant for the subset of patients having their first episode of P. carinii pneumonia. The yield of transbronchial biopsy was similar for both groups of patients (81% compared with 84%). The yield of bronchoscopy was not influenced by use of zidovudine. Review of lavage specimen slides suggested that there may be fewer organisms present in patients receiving aerosolized pentamidine. An atypical roentgenographic presentation of upper lobe predominant infiltrates was seen in 38% of the study patients and 7% of the control patients. In addition, pneumothoraces and cystic changes were also frequently seen in the study patients. Gallium scans, when done, were also atypical in the study group. Markers of the severity of disease, however, were similar in both groups. The yield of bronchoalveolar lavage for P. carinii pneumonia in HIV-infected patients is lower in patients receiving aerosolized pentamidine. Unusual roentgenographic presentations and atypical gallium scans are also found in this setting

Metastatic Prostate Adenocarcinoma Presenting Central Diabetes Insipidus

Full Text Available The pituitary gland and infundibulum can be involved in a variety of medical conditions, including infiltrative diseases, fungal infections, tuberculosis, and primary and metastatic tumors. Metastases to the pituitary gland are absolutely rare, and they are generally secondary to pulmonary carcinoma in men and breast carcinoma in women. Pituitary metastases more commonly affect the posterior lobe and the infundibulum than the anterior lobe. The posterior lobe involvement may explain why patients with pituitary metastases frequently present with diabetes insipidus. We are presenting a case report of a 78-year-old male patient who had metastatic prostate with sudden onset of polyuria and persistent thirst. He had no electrolyte imbalance except mild hypernatremia. The MRI scan of the brain yielded a suspicious area in pituitary gland. A pituitary stalk metastasis was found on magnetic resonance imaging (MRI of pituitary. Water deprivation test was compatible with DI. A clinical response to nasal vasopressin was achieved and laboratory results revealed central diabetes insipidus. As a result, the intrasellar and suprasellar masses decreased in size, and urinary output accordingly decreased.

Tonic spasms (TS) are involuntary movement patterns that can present in patients with multiple sclerosis (MS). They have been first described decades ago, but are frequently missed and misdiagnosed, particularly in the pediatric MS patients and if appearing ahead of hallmark neurological signs and symptoms of MS. Slovenia is a country with the population of about 2 million people. In the years from 1992 to 2016, we have treated 57 sequential pediatric patients with MS at our hospital, which is the only tertiary medical institution for treating children with MS in the country. We present the only two MS patients, a 17-year-old girl and a 14-year-old boy, whose first manifestation of MS were TS. This allowed us to estimate the incidence of TS in pediatric MS patients in Slovenia. Copyright © 2017 Elsevier B.V. All rights reserved.

A 33-year-old, previously healthy male presented with respiratory distress and underwent intubation. A physical examination revealed a holosystolic murmur and pupillary abnormalities. Echocardiography revealed a flail anterior mitral valve leaflet with ruptured chordae and severe mitral regurgitation. The patient underwent urgent mitral valve replacement and tolerated the procedure well. The mitral valve leaflet was myxomatous and calcified -- an unusual find in such a patient. An ophthalmology consultation was obtained and the patient diagnosed with Axenfeld-Rieger syndrome, a disorder of the anterior ocular chamber that has been associated with cardiac malformations. The present case report adds to the body of literature which suggests a correlation between Axenfeld-Rieger syndrome and valvular abnormalities. Hence, it is believed prudent that patients with Axenfeld-Rieger syndrome should undergo echocardiographic screenings for valvular abnormalities.

Han, Y-N

2009-01-01

This study aimed to identify acute self-limited hepatitis B (ASL-HB) among patients presenting with hepatitis B virus (HBV)-related acute hepatitis. Data were available for 220 patients diagnosed with HBV-related acute hepatitis, of whom 164 had acute hepatitis B (AHB). Of these, 160 were confirmed as ASL-HB: three (1.9%) evolved to chronic hepatitis B and one (0.6%) developed fulminant hepatitis and died. Comparisons were also made between AHB and acute infections with hepatitis A (HA) and hepatitis E (HE) viruses. During the study period, the number of patients with AHB exceeded the sum of those with acute HA and acute HE infections. There was no distinct seasonal peak for AHB infection, whereas both acute HA and acute HE infections occurred more frequently in the spring. Clinical symptoms and physical signs were similar for all three types of hepatitis, but significant differences were seen in some biochemical parameters. In conclusion, this study suggests that symptomatic AHB is not rare in China but it seldom evolves to chronic hepatitis B.

The study includes 159 SLE patients seen between 1987 and 2011, of whom 116 were treated in the public health system and 43 in private practice. In the comparison between both groups, it was shown that patients in the public health system were younger at first consultation and at the onset of SLE, and that the mean duration of their disease prior to nephropathy was statistically significantly shorter. They also presented with more SLE activity (measured by Systemic Lupus Erythematosus Activity Index) such as fever, lower levels of C4, and elevated erythrocyte sedimentation rate. Although cyclophosphamide was administered more frequently to patients in the public health system group, there were no statistically significant differences in renal histological findings. A second renal biopsy was performed on 20 patients due to the presence of persistent proteinuria, peripheral edema, urinary casts, or because of previous defective renal specimens. The overall 10-year survival of the patients in the public health system was 78% compared to a survival rate of 91% for the patients in private practices. When survival was evaluated at 15 years, however, no differences were found (log rank test: 0.65). Patients from both public and private groups attended medical specialist practices and received early diagnoses and close follow-ups. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

Background : A cross-sectional study to investigate the association of Osteoporosis Self-Assessment Tool for Asians (OSTA) score with clinical presentation and expenditure of hospitalized adult trauma patients with femoral fractures. Methods : According to the data retrieved from the Trauma Registry System between 1 January 2009 and 31 December 2015, a total of 2086 patients aged ≥40 years and hospitalized for treatment of traumatic femoral bone fracture were categorized as high-risk patients (OSTA -1, n = 638). Two-sided Pearson's, chi-squared, or Fisher's exact tests were used to compare categorical data. Unpaired Student's t -test and Mann-Whitney U -test were used to analyze normally and non-normally distributed continuous data, respectively. Propensity-score matching in a 1:1 ratio was performed using Number Crunching Statistical Software (NCSS) software (NCSS 10; NCSS Statistical Software, Kaysville, UT, USA), with adjusted covariates including mechanism and Glasgow Coma Scale (GCS); injuries were assessed based on the Abbreviated Injury Scale (AIS), and Injury Severity Score (ISS) was used to evaluate the effect of OSTA-related grouping on a patient's outcome. Results : High-risk and medium-risk patients were predominantly female, presented with significantly older age and higher incidences of co-morbidity, and were injured in a fall accident more frequently than low-risk patients. High-risk patients and medium-risk patients had a different pattern of femoral fracture and a significantly lower ISS. Although high-risk and medium-risk patients had significantly shorter lengths hospital of stay (LOS) and less total expenditure than low-risk patients did, similar results were not found in the selected propensity score-matched patients, implying that the difference may be attributed to the associated injury severity of the patients with femoral fracture. However, the charge of surgery is significantly lower in high-risk and medium-risk patients than in low

Full Text Available Background. Renal cell carcinoma (RCC has unpredictable and diverse behavior. The classic triad of hematuria, loin pain, and abdominal mass is uncommon. At time of diagnosis, 25%–30% of patients are found to have metastases. Bones, lungs, liver, and brain are the frequent sites of metastases. RCC with metastasis to the head and neck region and thyroid gland is the rarest manifestation and anaplastic carcinoma behaving metastatic thyroid mass is an extremely rare presentation of RCC. Case Presentation. A 56-year-old Saudi man with past history of right radical nephrectomy 5 years back presented with 3 months history of rapid increasing neck mass with dysphagia, presenting like anaplastic thyroid carcinoma. Tru-cut biopsy turned out to be metastatic renal cell carcinoma. Patient was treated with radiation therapy 30 Gy in 10 fractions to mass. Patient died 4 months after the discovery of anaplastic thyroid looking metastasis. Conclusion. Rapidly progressing thyroid metastases secondary to RCC are rare and found often unresectable which are not amenable to surgery. Palliative radiotherapy can be considered for such patients.

Topiramate is an approved and effective drug in migraine prophylaxis. Paresthesia is the most commonly reported side effect. The primary objective of this study was to compare the frequency of topiramate-induced paresthesia in migraine headache to epileptic patients. Patients with migraine without aura and epilepsy were enrolled in this observational study. All cases were interviewed by telephone about their history of paresthesia. Confounding factors were controlled through logistic regression. The odds ratio of developing topiramate-induced paresthesia in migraine compared to epilepsy patients was 3.4. Three factors were independent contributors to developing topiramate-induced paresthesia: female sex (odds ratio 2.1), topiramate dosage (odds ratio 0.3) and duration of therapy. Our findings indicate an independent association between migraine and development of paresthesia. Migraineurs were more likely than epileptic patients to report paresthesia as topiramate adverse effects. Female sex, treatment duration and topiramate dosage contribute significantly to subsequent development of paresthesia.

In an acute promyelocytic leukemia (APL)-transplantable mouse model, we previously reported the presence of antibodies recognizing PML-RARalpha and RARalpha in the sera of ATRA-treated mice. To evaluate this immune response, we determined the prevalence of anti-RARalpha antibodies in a cohort of 48 APL mice, treated by ATRA (n = 24) or by placebo pellets (n = 24), and in a preliminary subset of 9 patients with APL using a specific enzyme-linked immunosorbent assay (ELISA). In APL mice, significantly higher antibody levels were observed at the latest time points (day 48 to 58 levels superior to day 15 to 18 or day 28 to 38 levels). Antibody levels were higher in ATRA-treated mice than in placebo-treated mice and were also predictive of better survival. In the patients with APL, anti-RARalpha antibodies were detected at diagnosis and after maintenance therapy, reminiscent of the ATRA-treated APL mice. Antinuclear or antineutrophil cytoplasmic autoantibodies were also detected. These data reveal for the first time that in patients with APL an immune response may be detected at diagnosis and enhanced after maintenance therapy.

Present-day concepts in radiodiagnosis of acute pneumonias in children

Mirimova, T.D.; Zhakova, I.I.

1987-01-01

An X-ray study of 300 children with pneumonias of various etiology has shown that Pneumococcus is the most frequent cause of pneumonia whereas Hemophilus and Mycoplasma pneumonia are observed less frequently. The most common types are segmental (41%), lobular (30%), focal-confluent (20%) and focal (9%). Pleuritis complicated a course of pneumonia in more than half of the patients. Pulmonary destructive changes were most frequent in pneumococcal pneumonia (20%), less frequent in Hemophilus pneumonia and undetectable in Mycoplasma pneumonia

2015-01-01

An expanded hexanucleotide repeat in C9ORF72 has been identified as the most common genetic cause of amyotrophic lateral sclerosis and/or frontotemporal dementia in many populations, including the Greek. Recently, C9ORF72 expansions were reported as the most common genetic cause of Huntington disease (HD) phenocopies in a UK population. In the present study, we screened a selected cohort of 40 Greek patients with HD phenocopies for C9ORF72 hexanucleotide repeat expansions using repeat-primed polymerase chain reaction. We identified 2 patients (5%) with pathologic expansions. The first patient had chorea, behavioral-psychiatric disturbance, cognitive impairment, and a positive family history, fulfilling the strictest criteria for HD phenocopy. The second patient was sporadic and had parkinsonism, behavioral-psychiatric disturbance, and cognitive impairment, corresponding to a broader definition of HD phenocopy. These findings identify C9ORF72 expansions as a frequent cause of HD phenocopies in the Greek population, confirming recent findings in other populations and supporting proposed diagnostic testing for C9ORF72 expansions in patients with HD-like syndromes.

Dysphagia is a common symptom with diverse etiology in otolaryngology. In the present study clinicopathological, radiological and endoscopic evaluation of patients was done in a tertiary care hospital in patients presenting with dysphagia. A prospective nonrandomized observational study was carried out on total of 80 cases having dysphagia during March 2015 to August 2016. In the present study, out of 80 patients, youngest case was a three years old child while oldest case was an 85 years old female. The mean age was 48.3 ± 20.3 years. The majority of cases were in age group 41-59 years (35%). Male to female ratio was 2.33:1. The mean duration of illness was 15.44 weeks. 15% of patients had absolute dysphagia. For detecting the lesion, Barium swallow study (BSS) showed a total sensitivity of 49.05% (n = 53), Computerised Tomography (CT) showed a total sensitivity of 85.70% (n = 49), plain skiagram neck & chest showed a total sensitivity of 88.88% (n = 9) and endoscopy was the most sensitive test overall as it showed a total sensitivity of 98.75% (n = 80). No complications were reported with either rigid or flexible endoscopy. Dysphagia is a common presenting complaint in otolaryngology with cases coming directly or being referred from other specialities. Males are more commonly affected than females and incidence of malignancy increases with age. Endoscopy can become the first screening test in dysphagia due to its high sensitivity and low risk of complications, with radiological tests being done in an adjunct manner.

Full Text Available Background. There have been inconsistent reports on the prevalence and pathogenicity of anti-Aquaporin 4 (AQP4 in patients presented with idiopathic inflammatory demyelinating diseases (IIDDs. Objective. To estimate the prevalence of anti-AQP4 antibody in patients with IIDDs presented to University Malaya Medical Centre in terms of patients’ clinical and radiological presentations and prognoses. Methods. Retrospective data review of IIDDs patients presented from 2005 to 2015. Patients were classified into classical multiple sclerosis (CMS, opticospinal (OS presentation, optic neuritis (ON, transverse myelitis (TM, brainstem syndrome (BS, and tumefactive MS. Anti-Aquaporin 4 antibody was tested using the Indirect Immunofluorescence Test (IIFT cell-based assay. Statistical analysis was done using the SPSS version 20. Results. Anti-AQP4 antibody was detected in 53% of patients presented with IIDDs. CMS was more common in the seronegative group, 27/47 (57.45%; p<0.001. Conversely, OS involvement was more common in the seropositive group, 26/53 (49.06%; p<0.001. Longitudinally extensive spinal cord lesions (LESCLs on MRI were also more common in the seropositive group, 29/40 (72.50%; p=0.004. Only 2/40 (5.00% had MRI evidence of patchy or multiple short-segment spinal cord lesions in the AQP4-positive group (p=0.003. The relapse rate and Expanded Disability Status Scale (EDSS were also higher in the seropositive group (5.43 versus 3.17, p=0.005; 4.07 versus 2.51, p=0.006, resp.. Typical clinical presentations that defined NMO were also seen in the seronegative patients, but in a lower frequency. Conclusion. Our cohort of patients had a higher prevalence of seropositivity of anti-AQP4 antibody as compared to those in Western countries. This was also associated with a more typical presentation of opticospinal involvement with LESCLs on MRI, a higher rate of relapse, and EDSS.

This study in a regional hospital setting found a low evaluation rate for osteoporosis among patients presenting with a rib fracture. Increased emphasis or education for osteoporosis evaluation may be necessary in case of rib fractures. Rib fractures from a low-energy trauma are common in the elderly, and a history of rib fracture has been reported to increase the risk for a subsequent osteoporotic fracture. The purpose of this study was to evaluate how many of the patients presenting with an isolated rib fracture were being evaluated for osteoporosis and the risk for a subsequent fracture. We retrospectively reviewed all patients aged 50 years or older who were diagnosed with a rib fracture between January 2011 and April 2016 at a regional tertiary care university hospital near Seoul, South Korea. We excluded those who had been treated for osteoporosis or those with other concomitant fractures or fractures from a motor vehicle accident or cancer. We evaluated the frequency of dual energy X-ray absorptiometry (DXA) scan examinations in these patients. There were 231 patients with isolated rib fractures (132 men and 99 women). The mean age was 65 years. Rib fractures were most commonly diagnosed at the emergency department and most of the patients were referred to the department of thoracic surgery for follow-up evaluations. Of these 231 patients, 29 (12%) had DXA examinations after the injury, and only 9 (4%) of them did so within 6 months. Physicians specializing in orthopedic surgery, family medicine, internal medicine, rehabilitation medicine, and emergency medicine were ordering the examination. This study in a regional hospital setting found a low evaluation rate for osteoporosis among patients presenting with a rib fracture. This study suggests that increased emphasis or education for osteoporosis evaluation may be necessary for physicians who are often referred to for care of rib fractures.

Immunocompromised patients, especially those receiving treatment with corticosteroids and cytotoxic chemotherapy are at increased risk for developing Legionella pneumonia. The aim of this study was to determine clinical and radiographic characteristics of pulmonary infection due to Legionella in persons undergoing treatment for cancer and stem cell transplant (SCT) recipients. Retrospective review of Legionella cases at MSKCC over a fifteen-year study period from January 1999 and December 2013. Cases were identified by review of microbiology records. During the study period, 40 cases of Legionella infection were identified; nine among these were due to non-pneumophila species. Most cases occurred during the summer. The majority [8/9, (89%)] of patients with non-pneumophila infection had underlying hematologic malignancy, compared to 18/31 (58%) with Legionella pneumophila infections. Radiographic findings were varied-nodular infiltrates mimicking invasive fungal infection were seen only among patients with hematologic malignancy and hematopoietic stem cell transplant (SCT) recipients and were frequently associated with non-pneumophila infections (50% vs 16%; P = 0.0594). All cases of nodular Legionella pneumonia were found incidentally or had an indolent clinical course. Legionella should be considered in the differential diagnosis of nodular lung lesions in immunocompromised patients, especially those with hematologic malignancy and SCT recipients. Most cases of nodular disease due to Legionella are associated with non-pneumophila infections. Copyright © 2015 The British Infection Association. Published by Elsevier Ltd. All rights reserved.

Extremely frequent behavior in consumer research: theory and empirical evidence for chronic casino gambling.

Perfetto, Ralph; Woodside, Arch G

2009-09-01

The present study informs understanding of customer segmentation strategies by extending Twedt's heavy-half propositions to include a segment of users that represent less than 2% of all households-consumers demonstrating extremely frequent behavior (EFB). Extremely frequent behavior (EFB) theory provides testable propositions relating to the observation that few (2%) consumers in many product and service categories constitute more than 25% of the frequency of product or service use. Using casino gambling as an example for testing EFB theory, an analysis of national survey data shows that extremely frequent casino gamblers do exist and that less than 2% of all casino gamblers are responsible for nearly 25% of all casino gambling usage. Approximately 14% of extremely frequent casino users have very low-household income, suggesting somewhat paradoxical consumption patterns (where do very low-income users find the money to gamble so frequently?). Understanding the differences light, heavy, and extreme users and non-users can help marketers and policymakers identify and exploit "blue ocean" opportunities (Kim and Mauborgne, Blue ocean strategy, Harvard Business School Press, Boston, 2005), for example, creating effective strategies to convert extreme users into non-users or non-users into new users.

Miranda, Stephen P; Kimmell, Kristopher T; Silberstein, Howard J

2016-01-01

Chiari I malformation (CM-I) is defined by cerebellar tonsillar herniation through the foramen magnum. Patients typically present with chronic complaints, including headache, dizziness, and numbness, although there are few reports in the literature of pediatric patients presenting acutely with neurological deficit caused by CM-I. We report a child who presented acutely with hemiparesis and magnetic resonance imaging findings consistent with CM-I and spinal cord edema. A 3-year old boy with normal development presented with difficulty walking and increased drooling. His mother stated he was running into objects and had balance issues for several days. Neurological examination showed ataxia with falling to the right after a few steps and weakness of the right arm and leg. His medical history was remarkable only for mild asthma, although he had recently been treated for an upper respiratory viral infection. Computed tomography of the head demonstrated no brainstem mass. Magnetic resonance imaging of the head and cervical spine showed tonsillar ectopia approximately 2 cm below the craniocervical junction with increased T2 signal in the spinal cord from C1 to C3 consistent with syringomyelia and cord edema. The patient underwent suboccipital craniectomy with removal of the posterior arch of C1 and dural patch graft. His postoperative course was unremarkable, with complete resolution of his symptoms at his 1-month follow-up visit. This case highlights an unusual presentation of CM-I with neurological deficit related to spinal cord edema, possibly precipitated by the "water-hammer" effect of this patient's coughing fits. Providers should be aware of the acute presentations of CM-I. Copyright © 2016 Elsevier Inc. All rights reserved.

Acromegaly is a rare, slowly progressive disorder resulting from excessive growth hormone (GH) production by a pituitary somatotroph tumor. The objective of this study was to examine acromegaly treatment outcomes during long-term care at a specialized pituitary center in patients presenting with lack of biochemical control. Data came from an acromegaly registry at the Cedars-Sinai Medical Center Pituitary Center (center). Acromegaly patients included in this study were those who presented biochemically-uncontrolled for care at the center. Biochemical control status, based on serum insulin-like growth factor-1 values, was determined at presentation and at study end. Patient characteristics and acromegaly treatments were reported before and after presentation by presenting treatment status and final biochemical control status. Data on long-term follow-up were recorded from 1985 through June 2013. Seventy-four patients presented uncontrolled: 40 untreated (54.1%) and 34 (45.9%) previously-treated. Mean (SD) age at diagnosis was 43.2 (14.7); 32 (43.2%) were female patients. Of 65 patients with tumor size information, 59 (90.8%) had macroadenomas. Prior treatments among the 34 previously-treated patients were pituitary surgery alone (47.1%), surgery and medication (41.2%), and medication alone (11.8%). Of the 40 patients without prior treatment, 82.5% achieved control by study end. Of the 34 with prior treatment, 50% achieved control by study end. This observational study shows that treatment outcomes of biochemically-uncontrolled acromegaly patients improve with directed care, particularly for those that initially present untreated. Patients often require multiple modalities of treatment, many of which are offered with the highest quality at specialized pituitary centers. Despite specialized care, some patients were not able to achieve biochemical control with methods of treatment that were available at the time of their treatment, showing the need for additional

The electrocardiogram (ECG) is often used in the diagnosis of patients presenting with chest pain to emergency departments. Because chest pain is a common manifestation of type A acute aortic dissection (TAAAD), ECGs are obtained in much of this population. We evaluated the effect of particular ECG patterns on the diagnosis and treatment of TAAAD. TAAAD patients (N = 2,765) enrolled in the International Registry of Acute Aortic Dissection were stratified based on normal (n = 1,094 [39.6%]) and abnormal (n = 1,671 [60.4%]) findings on presenting ECGs and further subdivided according to specific ECG findings. Time data are presented in hours as medians (quartile 1 to quartile 3). Patients with ECGs with abnormal findings presented to the hospital sooner after symptom onset than those with ECGs with normal findings (1.4 [0.8 to 3.3] vs 2.0 [1.0 to 3.3]; p = 0.005). Specifically, this was seen in patients with infarction with new Q waves or ST elevation (1.3 [0.6 to 2.7] vs 1.5 [0.8 to 3.3]; p = 0.049). Interestingly, the time between symptom onset and diagnosis was longer with infarction with old Q waves (6.7 [3.2 to 18.4] vs 5.0 [2.9 to 11.8]; p = 0.034) and nonspecific ST-T changes (5.8 [3.0 to 13.8] vs 4.5 [2.8 to 10.5]; p = 0.002). Surgical mortality was higher in patients with abnormal ECG findings (20.6% vs 11.9%, p presenting with abnormal ECG results are sicker, have more in-hospital complications, and are more likely to die. The frequency of nonspecific ST-T abnormalities and its association with delay in diagnosis and treatment presents an opportunity for practice improvement.

Cannabis consumption patterns among frequent consumers in Uruguay.

Boidi, María Fernanda; Queirolo, Rosario; Cruz, José Miguel

2016-08-01

In 2013, Uruguay became the first country to fully regulate the cannabis market, which now operates under state control. Cannabis can be legally acquired in three ways: growing it for personal use (self-cultivation), cannabis club membership, and from pharmacies (not yet implemented). Users must be entered into a confidential official registry to gain access. This article presents findings of a Respondent Driven Sample survey of 294 high-frequency cannabis consumers in the Montevideo metropolitan area. Frequent consumers resort to more than one method for acquiring cannabis, with illegal means still predominating after 1 year of the new regulation law. Cannabis users overwhelmingly support the current regulation, but many of them are reluctant to register. Some of the attitudes and behaviors of the high-frequency consumers pose a challenge to the success of the cannabis law. Individuals relying on more than one method of access defy the single access clause, a prerequisite for legal use, while the maximum amount of cannabis individuals can access monthly seems too high even for most frequent consumers, which might promote the emergence of a grey market. Reluctance to register among a significant proportion of high-frequency consumers raises doubts about the law's ability to achieve its stated objectives. Copyright © 2016 Elsevier B.V.

Anal canal duplication (ACD) is the rarest of gastrointestinal duplications. Few cases have been reported. Most cases present as an opening in the midline, posterior to the normal anus. The aim of our revision is to contribute with eight new cases, some of them with unusual presentations: five presented as the typical form, one with a perianal nodule, and two presented as two separate orifices (anal canal triplication). Complete excision was performed in all patients with no complications. ACD is the most distal and the least frequent digestive duplication. Its treatment should be surgical excision, to avoid complications such as abscess, fistulization, or malignization. Anal canal triplication has never been described before.

Background Hallux valgus and hallux rigidus are common foot conditions that lead to a deterioration in health status. Patients with significant pain or deformity from these conditions frequently resort to surgery. In this project, the foot health status of patients with hallux valgus and hallux rigidus presenting to foot surgeons in Australia was compared. Methods Foot health status was measured in 120 participants using the Foot Health Status Questionnaire (FHSQ), a validated 0 – 100 point health status instrument. All participants had presented for surgical advice regarding hallux valgus/rigidus. The mean age of participants was 48.0 years (SD ± 14.3, range 19 – 79). Results In the sample, 68% of participants were diagnosed with hallux valgus and 32% with hallux rigidus. Participants with hallux rigidus had greater levels of pain and functional limitation compared with hallux valgus. The mean difference for pain was 13.8 points (95% CI 4.6 to 22.9) and the mean difference for function was 15.0 points (95% CI 5.3 to 24.7). Both conditions result in similarly negative levels of impact on shoe fit and overall foot health. Conclusion This study found measurable differences in foot health status between hallux valgus and hallux rigidus in participants presenting for surgical consultation. While both appear to have a negative impact on health status, hallux rigidus has a more significant impact. PMID:19077213

Guidelines issued by European and German cardiology societies clearly define procedures for treatment of acute myocardial infarction (AMI). These guidelines, however, are based on clinical studies in which older patients are underrepresented. Older patients, on the other hand, represent a large and growing portion of the infarction population. It was our goal in the present paper to analyse the present treatment of AMI patients over 75 years of age in the city of Berlin, Germany, with data gained from the Berlin Myocardial Infarction Registry (BHIR). We prospectively collected data from 5079 patients (3311 men and 1768 women, mean age 65.6) with acute myocardial infarction who were treated in 25 hospitals in Berlin during the period 1999-2003. 1319 patients (25.9%) were older than 75 (mean age 82.5 years). Overall hospital mortality rate was 11.6%. In patients over 75, this rate was 23.9%; among the younger infarction population, it was 7.3%. In contrast to the younger AMI patients, the majority of those over 75 were female (62.5 vs 25.1% for the younger) and demonstrated a significantly higher frequency of all prognostically meaningful comorbidities (heart failure 14.4% vs. 3.5%; renal failure 11.5 vs 3.9%; diabetes 37.3 vs 24.3%). Clinical signs of severe infarction, moreover, were more common among the aged patients (pulmonary congestion 45.4 vs 19.7%; left bundle branch block 12.7 vs 3.6%). Pre-hospital time was prolonged (2.8 vs 2 h) and guideline-recommended therapy was applied significantly less frequently to AMI patients over 75 (reperfusion therapy 39.8 vs 71.7%, beta-blockers 62.8 vs 78.3%, statins 26.5 vs 45.5%). Multivariate analysis revealed the following factors to be independent predictors of hospital mortality in patients over 75: age (OR 1.05 per year), acute heart failure (OR 2.39), pre-hospital resuscitation (OR 10.6), cardiogenic shock (OR 2.73), pre-hospital delay >12 h (OR 1.68), and ST elevation in the first ECG (OR 2.09).

The Internet is a staple of electronic communication and is essential to the emerging telemonitoring and health information technology interventions for adults with chronic diseases. To identify determinants of frequent Internet use in an urban kidney transplant population in the United States. A single center, cross-sectional survey study. An urban Midwestern transplant center. 78 pretransplant and 177 posttransplant patients. Frequent Internet use, defined as using the Internet more than 5 hours per week. Only 38% of participants reported being frequent Internet users. Non-Hispanic blacks and participants who reported their race/ethnicity as "other" were significantly less likely than whites to report being frequent Internet users. Women were 59% less likely than men to be frequent users of the Internet. Those who reported having kidney disease for more than 3 years were more likely to report being frequent Internet users. As education increased, Internet use increased. As age increased, Internet use decreased. Alternatives to electronic information sources and/or additional resources should be considered for those who may fall in the so-called digital divide.

To test the hypothesis that there is no difference in trapeziometacarpal (TMC) joint arthrosis-related symptoms and disability between patients seeking treatment for symptoms of TMC arthrosis and those with incidental TMC joint arthrosis. We compared 64 patients presenting for care of TMC joint arthrosis with 64 with incidental TMC joint arthrosis. For both groups, the diagnosis was based on crepitation on examination. Bivariate and multivariate analyses assessed factors associated with symptoms and disability related to TMC joint arthrosis. In bivariate analysis, patients presenting for care of TMC joint arthrosis had significantly more symptoms and disability from TMC joint arthrosis than those with incidental TMC joint arthrosis. The best multivariate linear regression model for fewer TMC joint arthrosis-related symptoms and disability included patients with incidental TMC joint arthrosis, male sex, no other painful conditions, less catastrophic thinking, and fewer depressive symptoms and explained 74% of the variability. Having incidental TMC joint arthrosis (25%) and more adaptive coping strategies (less catastrophic thinking; 5%) were the most important contributors to fewer symptoms and less disability. Future studies are merited to determine whether training in better coping strategies (eg, less catastrophic thinking and fewer depressive symptoms) can decrease symptoms and disability in patients with TMC joint arthrosis.

High-need, high-cost (HNHC) patients can over-use acute care services, a pattern of behavior associated with many poor outcomes that disproportionately contributes to increased U.S. healthcare cost. Our objective was to reduce healthcare cost and improve outcomes by optimizing the system of care. We targeted HNHC patients and identified root causes of frequent healthcare utilization. We developed a cross-continuum intervention process and a succinct tool called a Complex Care Map (CCM)© that addresses fragmentation in the system and links providers to a comprehensive individualized analysis of the patient story and causes for frequent access to health services. Using a pre-/post-test design in which each subject served as his/her own historical control, this quality improvement project focused on determining if the interdisciplinary intervention called CCM© had an impact on healthcare utilization and costs for HNHC patients. We conducted the analysis between November 2012 and December 2015 at Mercy Health Saint Mary's, a Midwestern urban hospital with greater than 80,000 annual emergency department (ED) visits. All referred patients with three or more hospital visits (ED or inpatient [IP]) in the 12 months prior to initiation of a CCM© (n=339) were included in the study. Individualized CCMs© were created and made available in the electronic medical record (EMR) to all healthcare providers. We compared utilization, cost, social, and healthcare access variables from the EMR and cost-accounting system for 12 months before and after CCMs© implementation. We used both descriptive and limited inferential statistics. ED mean visits decreased 43% (pcost of care.

Purpose: While patients with glioblastoma multiforme (GBM) who present with midline shift have a presumably worse prognosis, there is little literature evaluating the prognostic significance of this presentation in multivariate analysis in the context of other known prognostic factors. Methods and Materials: From March 1981 to September 1993, 219 patients underwent irradiation for intracranial glioma at our institution. One hundred fourteen patients with a diagnosis of a primary GBM were analyzed for the influence of the presence of midline shift at diagnosis on survival with respect to other known prognostic factors, including age, Karnofsky performance status (KPS), and extent of surgery. Eighty-five patients (74%) presented with midline shift. Surgical treatment consisted of subtotal/total resection in 86 patients (75%). Among patients presenting with midline shift, 68 (80%) underwent subtotal/total resection before irradiation. Results: Multivariate analysis of the entire cohort of patients found none of the potential prognostic factors analyzed to significantly influence survival. The overall median survival was 6 months. However, when multivariate analysis was limited to patients with a KPS of ≥ 70, only the presence of midline shift and age were found to significantly influence survival. Patients with a KPS ≥ 70 and with midline shift present at diagnosis had a median survival of 8 months, as compared to 14 months for those not having midline shift at presentation (p = 0.04). Patients with a KPS ≥ 70 and age > 50 years had a median survival of 5 months as compared to 11 months for those ≤ 50 (p 0.02). Conclusion: In this series, where 80% of patients who presented with a midline shift underwent decompressive resection of GBM before irradiation, the presence of midline shift at diagnosis remained an independent prognostic factor influencing survival among good performance status patients. While the role of decompressive surgery in this setting is
