    Full Text Available The occurrence of liver disease and raised liver enzymes is common in diabetic patients and the increasing level of enzymes indicates the severity of hepatic injury. Very few studies have addressed this issue in Bangladesh though Bangladeshi population is very much susceptible to diabetes. This study investigated a total of 1400 diabetic patients and 100 non diabetic individuals to compare the level of liver enzymes between diabetic and non-diabetic subjects. The comparisons were made among subjects who were referred to the department of Gastro-hepato-pancreatic diseases (GHPD of BIRDEM with the clinical diagnosis of chronic hepatitis and other gastro-intestinal disorders. The investigations included alanine aminotransferase (ALT, aspartate aminotransferase (AST, alkaline phosphatase (ALP and bilirubin levels. The subjects were categorized with and without hepatitis based on these investigations. The biochemical markers (ALT, AST, ALP, bilirubin did not differ significantly between non-diabetic male and female subjects. Neither the differences were significant between diabetic males and females though the diabetic patients had higher level of markers. In contrast, when compared between diabetic and non-diabetic subjects there were striking differences in either sex. Compared with the non-diabetic the diabetic subjects had significantly higher level of ALT (48.3 vs. 277.0, AST (42.0 vs. 213.0 and ALP (148 vs. 302 in males (p<0.005 for all. Similarly, these values were found significantly higher in diabetic females than their non-diabetic counterparts (p<0.01. For bilirubin, it was also found significant in males (p<0.001. The study revealed that the liver enzymes were found elevated in both diabetic and non-diabetic subjects who were referred with clinically diagnosed hepatitis. The enzymes were found markedly elevated among the diabetic than non diabetic patients, which indicate hepatic injury was more marked among the diabetic patients. Further

    Total lung capacity (TLC), forced expiratory flow between 25 and 75% (FEF25-75%), peak expiratory flow (PEF), or post-bronchodilator volume response is recommended to detect obstructive abnormalities in the lung. The present study was performed to evaluate the usefulness of these pulmonary function test (PFT) parameters to diagnose obstructive lung disease in subjects with a restrictive pattern of spirometry. A retrospective study was conducted in 64 subjects with a restrictive pattern of spirometry (normal FEV1/FVC and low FVC) out of 3,030 patients who underwent all pre- and post-bronchodilator spirometry and lung volume measurement between April 2008 and December 2010. After subjects were clinically classified into those with obstructive lung disease, restrictive lung disease, and mixed lung disease, the agreements between the clinical diagnosis and PFT classification according to TLC, FEF(25-75%), PEF, and post-bronchodilator response criteria were compared. Of 64 subjects, 18 (28.1%) were classified with obstructive lung disease, 39 (60.9%) had restrictive lung disease, 1 (1.6%) had mixed lung disease, and 6 (9.4%) had no clinical lung disease. Among the 58 subjects with clinical lung disease, 22 (37.9%), 37 (63.8%), 33 (56.9%), and 3 (5.2%) were classified as having obstructive pattern based on TLC, FEF25-75%, PEF, and post-bronchodilator response criteria, respectively. The kappa coefficients for the agreement between the clinical classification and PFT classification using TLC, FEF25-75%, PEF, and post-bronchodilator response criteria in 58 subjects were 0.59, 0.18, 0.17, and spirometry, when obstructive lung disease is clinically suspected.

    This is a retrospective study that aimed at studying the diagnostic stability of psychiatric diagnoses over a 4-year period. Three-hundred and twelve patients (n = 312) admitted more than once to Al Ain in-patient unit from January 1, 1990 to December 31, 1993, were the subjects for this study. The sample included patients with the following index diagnoses: acute psychoses (n = 37), alcohol abuse (n = 15), bipolar disorder (n = 27), depressive disorders (n = 63), drug abuse (n = 21), hysteria (n = 23), neurotic disorders (n = 50) and schizophrenia (n = 76). Diagnoses on discharge for first admissions were considered the index diagnoses. The shift from index diagnoses to subsequent diagnoses was counted. Diagnostic stability was calculated as the percentages of index diagnoses that did not change over time. In nearly half of the patients the index diagnoses changed over the 4-year period. Highest diagnostic stability was found in patients with index diagnoses of alcohol abuse, schizophrenia and drug abuse (92%, 74% and 71% respectively), while the lowest stability was found in patients with neurotic, hysterical, depressive disorders, acute psychoses and bipolar disorders (38%, 48% and 45%, 42%, 52% respectively). Two distinct patterns of shifts were noted. First shift occurred between functional psychoses and second shift between depressive and neurotic disorders. This study provides further support to the notion that diagnostic stability in clinical practice is still far from being satisfactory.

    Full Text Available Objective. Genital herpes (GH recurrences and viral shedding are more frequent in the first year after initial HSV-2 infection. The objective of this study was to provide the first evaluation of valacyclovir 1 g once daily compared to placebo in reducing viral shedding in subjects newly diagnosed with GH. Methods. 70 subjects were randomized to receive valacyclovir 1 g daily or placebo in a crossover design for 60 days with a 7-day washout period. A daily swab of the genital/anal-rectal area was self-collected for HSV-2 detection by PCR. Subjects attended the clinic for routine study visits and GH recurrence visits. Treatment differences were assessed using a nonparametric crossover analysis. Results. 52 subjects had at least one PCR measurement in both treatment periods and comprised the primary efficacy population. Valacyclovir significantly reduced HSV-2 shedding during all days compared to placebo (mean 2.9% versus 13.5% of all days (P<.01, a 78% reduction. Valacyclovir significantly reduced subclinical HSV-2 shedding during all days compared to placebo (mean 2.4% versus 11.0% of all days (P<.01, a 78% reduction. However, 79% of subjects had no GH recurrences while receiving valacyclovir compared to 52% of subjects receiving placebo (P<.01. Conclusion. In this study, the frequency of total and subclinical HSV-2 shedding was greater than reported in earlier studies involving subjects with a history of symptomatic genital recurrences. Our study is the first to demonstrate a significant reduction in viral shedding with valacyclovir 1 g daily compared to placebo in a population of subjects newly diagnosed with HSV-2 infection.

    To examine the validity of diagnoses obtained by clinicians during routine clinical examination on acute psychiatric inpatient wards. N=100 inpatients with a broad spectrum of major mental disorders were randomly selected in a mental hospital's department of general psychiatry. Patients were diagnosed by independent assessors within Md = 5 (Range: 1-18) days of admission using the SCID I in order to examine the validity of the diagnoses given by the clinical staff based on routine assessments. The commonly used clinical examination technique had good overall agreement with the SCID I assessments regarding primary diagnoses at the level of ICD-10 main categories (F2, F30-31, F32-F33, F4; κ = 0.65). However, agreement between routine clinical diagnoses and the SCID I diagnoses tended to be low for some specific mental disorders (e.g., depressive disorders) and for secondary diagnoses. The validity of routine clinical diagnoses established in acute inpatient settings is limited and should be improved. Copyright © 2017 Elsevier B.V. All rights reserved.

    Clinicians routinely face conditions in which they have to decide whether the dental pulp can be saved or not. This study evaluated how reliable the clinical diagnosis of normal pulp/reversible pulpitis (savable pulp) or irreversible pulpitis (nonsavable pulp) is when compared with the histologic diagnosis. The study material consisted of 95 teeth collected consecutively in a general practice over a 5-year period and extracted for reasons not related to this study. Based on clinical criteria, teeth were categorized as having normal pulps, reversible pulpitis, or irreversible pulpitis. The former 2 were grouped together because they represent similar conditions in terms of prognosis. Teeth were processed for histologic and histobacteriologic analyses, and pulps were categorized as healthy, reversibly inflamed, or irreversibly inflamed according to defined criteria. The number of matching clinical/histologic diagnosis was recorded. The clinical diagnosis of normal pulp/reversible pulpitis matched the histologic diagnosis in 57 of 59 (96.6%) teeth. Correspondence of the clinical and histologic diagnosis of irreversible pulpitis occurred in 27 of 32 (84.4%) cases. Infection advancing to the pulp tissue was a common finding in teeth with irreversible pulpitis but was never observed in normal/reversibly inflamed pulps. Findings using defined criteria for clinical and histologic classification of pulp conditions revealed a good agreement, especially for cases with no disease or reversible disease. This means that the classification of pulp conditions as normal pulps, reversible pulpitis, and irreversible pulpitis has high chances of guiding the correct therapy in the large majority of cases. However, there is still a need for refined and improved means for reliable pulp diagnosis. Copyright © 2014 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

    Clinical trials are essential tools for the progress of clinical medicine in its diagnostic and therapeutic aspects. Since the first trial in 1948, which related tobacco use with lung cancer, there have been more than 150,000 clinical trials to date in various areas (paediatrics, cardiology, oncology, endocrinology, etc.). This article highlights the importance for all physicians to participate, over the course of their professional career, in a clinical trial, due to the inherent benefits for patients, the progress of medicine and for curricular prestige. The authors have created a synthesis of their experience with clinical trials on hypertension, diabetes, dyslipidaemia and ischaemic heart disease over the course of almost 3 decades. Furthermore, a brief reference has been made to the characteristics of a phase I unit, as well as to a number of research studies currently underway.

    Transsexual subjects are individuals who have a desire to live and be accepted as a member of the opposite sex, usually accompanied by a sense of discomfort with, or inappropriateness of, one's anatomic sex, and a wish to have surgery and hormonal treatment to make one's body as congruent as possible with one's preferred sex. They seek to develop the physical characteristics of the desired gender, and should undergo an effective and safe treatment regimen. The goal of treatment is to rehabilitate the individual as a member of society in the gender he or she identifies with. Sex reassignment procedures necessary for the treatment of transsexual patients are allowed in our country, at Medical Services that have a multidisciplinary team composed of a psychologist, a social worker, a psychiatrist, an endocrinologist and surgeons (gynecologists, plastic surgeons, and urologists). Patients must be between 21 to 75 years old and in psychological and hormonal treatment for at least 2 years. Testosterone is the principal agent used to induce male characteristics in female transsexual patients, and the estrogen is the chosen hormone used to induce the female sexual characteristics in male transsexual patients. Based on our 15 years of experience, we can conclude that testosterone and estradiol treatment in physiological doses are effective and safe in female and male transsexual patients, respectively.

    As individuals with HIV infection are living longer, the management of psychiatric disorders has increasingly been incorporated into comprehensive care. Individuals were recruited from an outpatient HIV clinic to assess the prevalence and related associations of current psychiatric disorders and biomarkers. Of the 201 participants who completed the interviews, the median age was 43.5 years, and the majority was male and African American. Most were receiving HIV therapy and 78% of those had achieved virologic suppression. Prevalent psychiatric diagnoses included major depressive disorder, generalized anxiety, and agoraphobia. Alcohol and cocaine/crack abuse and dependence were common substance use disorders. Current receipt of HIV therapy was less common among those diagnosed with generalized anxiety disorder. Agoraphobia was the only disorder associated with unsuppressed viral load. Psychiatric and substance use disorders are highly prevalent among an urban HIV clinic population, although we identified few associations between psychiatric diagnoses and HIV diseases status. © The Author(s) 2014.

    Full Text Available Introduction/Aim. Clinical presentation and neurophysiological examination are crucial in diagnosing carpal tunnel syndrome (CTS. The aim of this study was to determine sensitivity and specificity of clinical examination for diagnosing of CTS in relation to neurophysiological evaluation. Methods. The sample included 181 patients referred to the neurologist for further diagnosis of pain and parestesias in the arm (81 women and 100 men mean age 42 ± 14 years and 52 ± 16 years, respectively. All the patients were neurophysiologicly tested. Results. Out of 181 patients, clinical findings were considered positive for CTS in 37 patients. The neurophysiological findings for CTS were positive in 60 patients. Both clinical and neurophysiological findings were positive in 31 patients and both findings were negative in 115 patients (sensitivity 0,51; specificity 0,95. Conclusion. Low sensitivity and high specificity suggest that it is easier to exclude rather than to accurately diagnose CTS based on clinical examination alone. Thus, there is the need for neurophysiological evaluation of patients with complains in the arm.

    Background Structural MRI is used to longitudinally monitor the progression of Alzheimer's disease from its presymptomatic to symptomatic phases. Using magnetic resonance imaging data from the Alzheimer's Disease Neuroimaging Initiative (ADNI), we tested the hypothesis that surgery would affect brain parameters associated with progression of dementia. Materials and Methods Brain images from the neuroimaging initiative database were used to study normal volunteer subjects and patients with mild cognitive impairment for the age group 55 to 90 inclusive. We compared changes in regional brain anatomy for three visits that defined two inter-visit intervals for a surgical cohort (n=41) and a propensity matched non-surgical control cohort (n = 123). The first interval for the surgical cohort contained the surgical date. Regional brain volumes were determined with Freesurfer and quantitatively described with J-image software (University of California at San Francisco). Statistical analysis used Repeated Measures ANCOVA (SPSS, v.18.0; Chicago, IL). Results We found that surgical patients, during the first follow-up interval (5–9 months), but not subsequently, had increased rates of atrophy for cortical gray matter and hippocampus, and lateral ventricle enlargement, as compared to non-surgical controls. A composite score of five cognitive tests during this interval showed reduced performance for surgical patients with mild cognitive impairment. Conclusions Elderly subjects after surgery experienced an increased rate of brain atrophy during the initial evaluation interval, a time associated with enhanced risk for postoperative cognitive dysfunction. Although there was no difference in atrophy rate by diagnosis, subjects with mild cognitive impairment suffered greater subsequent cognitive effects. PMID:22293721

    Leukemia cutis is an extramedullary manifestation of leukemia. The frequency and age distribution depend on the leukemia subtype. The clinical and morphological findings have a wide range of cutaneous manifestations and may present with nodular lesions and plaques. Rare manifestations include erythematous macules, blisters and ulcers which can each occur alone or in combination. Apart from solitary or grouped lesions, leukemia cutis may also present with an erythematous rash in a polymorphic clinical pattern. Consequently, leukemia cutis has to be distinguished from numerous differential diagnoses, i. e. cutaneous metastases of visceral malignancies, lymphoma, drug eruptions, viral infections, syphilis, ulcers of various origins, and blistering diseases. In the oral mucosa, gingival hyperplasia is the main differential diagnosis. The knowledge of the clinical morphology is of tremendously importance in cases in which leukemia was not yet known. © The Authors • Journal compilation © Blackwell Verlag GmbH, Berlin.

    Full Text Available BACKGROUND: We have recently shown a high prevalence of diabetes and obesity in rural Cameroon, despite an improved lifestyle. Diabetes in rural Africa remains underdiagnosed and its role in increasing risk of atherosclerosis in these populations is unknown. We investigated the prevalence of carotid atherosclerosis and cardiovascular risk factors in a population of subjects with recently-diagnosed diabetes from rural Cameroon. METHODOLOGY/PRINCIPAL FINDINGS: In a case-control study, carotid intima-media thickness (IMT was measured in 74 subjects with diabetes (diagnosed 0.9 mm was found in 4%, 45.9% and 20% of diabetic subjects at the common, bulb or internal carotid, respectively. Only 25% of patients had an HbA1c9%. The prevalence of diabetic subjects with abnormal levels of LDL-cholesterol, triglycerides, HDL-cholesterol or blood pressure was 45%, 16.6%, 15% and 65.7%, respectively. CONCLUSIONS: Carotid thickness is increased in subjects with diabetes from a rural area of Cameroon, despite the relatively recent diagnosis. These findings and the high rate of uncontrolled diabetes in this population support the increasing concern of diabetes and cardiovascular diseases in African countries and indicate the need for multifaceted health interventions in urban and rural settings.

    2016-08-01

    This article describes reasoning strategies used by clinicians in different diagnostic circumstances and how these modes of inquiry may allow further insight into the evaluation and treatment of patients. Specifically, it aims to make explicit the implicit logical considerations that guide a variety of strategies in the diagnostic process, as exemplified in specific clinical cases. It focuses, in particular, in strategies that clinicians use to move from a large set of possible diagnoses initially suggested by abductive inferences - the process of hypothesis generation that creates a diagnostic space - to a narrower set or even to a single 'best' diagnosis, where the criteria to determine what is 'best' may differ according to different strategies. Experienced clinicians should have a diversified kit of strategies - for example, Bayesian probability or inference to a lovely explanation - to select from among previously generated hypotheses, rather than rely on any one approach every time. © 2015 John Wiley & Sons, Ltd.

    Esophageal candidiasis mostly occurs in the immunocompromised host. However, it may also affect healthy people and is frequently asymptomatic. The clinical significance of asymptomatic esophageal candidiasis (AEC) is still unclear. The aims of the study were to investigate the prevalence of AEC during health inspection and to identify its predisposing factors and clinical significance. A total of 49,497 subjects who underwent a health inspection that included upper endoscopy were enrolled. We retrospectively reviewed the subject's self-reporting questionnaires, medical records and endoscopic findings. We considered "long-term" follow-up to be >6 months with at least one more follow-up endoscopy. One hundred and seventy (0.4%) subjects were endoscopically diagnosed as esophageal candidiasis and 141 subjects were AEC. Multivariate analysis revealed that old age (≥60 years) was an independent risk factor for AEC (OR, 1.862, p = 0.005). The number of subjects with long-term follow-up was 79 (195.3 person-years). Among these, AEC of 64 subjects (81.0%) had disappeared on the follow-up endoscopy and was not recurrent. The other 15 subjects had AEC diagnosed more than once on the follow-up endoscopy, and 5 of them were spontaneously healed during the follow-up period. The remaining 10 subjects whose candidiasis was sustained up to the last endoscopy did not complain of symptoms during the follow-up period, and their endoscopic findings did not worsen. AEC is rare and old age is the only risk factor. AEC does not require medical care because it is a self-limited disease.

    Fragile X Syndrome (FXS) is the second cause of intellectual disability after Down syndrome and the most prevalent cause of intellectual disability in males, affecting 1:5000-7000 men and 1:4000-6000 women. It is caused by an alteration of the FMR1 gene, which maps at the Xq27.3 band: more than 99% of individuals have a CGG expansion (>200 triplets) in the 5' UTR of the gene, and FMR1 mutations and duplication/deletion are responsible for the remaining (<1%) molecular diagnoses of FXS. The aim of this review was to gather the current clinical and molecular knowledge about FXS to provide clinicians with a tool to guide the initial assessment and follow-up of FXS and to offer to laboratory workers and researchers an update about the current diagnostic procedures. FXS is a well-known condition; however, most of the studies thus far have focused on neuropsychiatric features. Unfortunately, some of the available studies have limitations, such as the paucity of patients enrolled or bias due to the collection of the data in a single-country population, which may be not representative of the average global FXS population. In recent years, insight into the adult presentation of the disease has progressively increased. Pharmacological treatment of FXS is essentially symptom based, but the growing understanding of the molecular and biological mechanisms of the disease are paving the way to targeted therapy, which may reverse the effects of FMRP deficiency and be a real cure for the disease itself, not just its symptoms. The clinical spectrum of FXS is wide, presenting not only as an isolated intellectual disability but as a multi-systemic condition, involving predominantly the central nervous system but potentially affecting any apparatus. Given the relative high frequency of the condition and its complex clinical management, FXS appears to have an important economic and social burden.

In contrast to the more traditional view of glioma as a localized disease, it is becoming clear that global brain functioning is impacted, even with respect to functional communication between brain regions remote from the tumor itself. However, a thorough investigation of glioma-related functional connectomic profiles is lacking. Therefore, we constructed functional brain networks using functional MR scans of 71 glioma patients and 19 matched healthy controls using the automated anatomical labelling (AAL atlas and interregional Pearson correlation coefficients. The frequency distributions across connectivity values were calculated to depict overall connectomic profiles and quantitative features of these distributions (full-width half maximum (FWHM, peak position, peak height were calculated. Next, we investigated the spatial distribution of the connectomic profile. We defined hub locations based on the literature and determined connectivity (1 between hubs, (2 between hubs and non-hubs, and (3 between non-hubs. Results show that patients had broader and flatter connectivity distributions compared to controls. Spatially, glioma patients particularly showed increased connectivity between non-hubs and hubs. Furthermore, connectivity distributions and hub-non-hub connectivity differed within the patient group according to tumor grade, while relating to Karnofsky performance status and progression-free survival. In conclusion, newly diagnosed glioma patients have globally altered functional connectomic profiles, which mainly affect hub connectivity and relate to clinical phenotypes. These findings underscore the promise of using connectomics as a future biomarker in this patient population.

    High-functioning autism (HFA) and Aspergers syndrome (AS) are autism spectrum disorders (ASD) characterised by disturbances in social interaction, both verbal and non-verbal communication and repetitive and/or restrictive behaviour since early childhood. Symptoms appear generally during early childhood and adolescence. The increasing need to clarify diagnostic queries in advanced age led to the constitution of specialised outpatient clinics for adults involving a growing amount of HFA/AS subjects diagnosed late in life. However, thus far neuropsychological data about this group are scarce. We present a subgroup of 39 patients with HFA/AS (mean age at diagnosis 31.1 ± 8.9 years) who were consecutively diagnosed at the autism outpatient clinic at the Department of Psychiatry at the University Hospital Cologne. Autistic symptoms (autism spectrum quotient; AQ), depressive symptoms (Beck depression inventory; BDI), general intelligence (HAWIE-R), social cognition ("theory of mind", ToM) and executive functioning (COWAT) were systematically studied in comparison to a control group matched for age, education, gender and intelligence (n = 39). HFA/AS subjects presented higher AQ scores (40.4 ± 5.2) as opposed to the healthy controls (13.5 ± 4.8). Neuropsychologically, patients showed deficits in social cognition, executive functions and in subtests of HAWIE-R related to verbal comprehension and perceptual organisation as opposed to the healthy control group. The diagnosis of autistic disorders in adulthood basically relies on the clinical assessment of autistic core symptoms which were corroborated by high AQ values. The self-rating instrument AQ was found to be highly discriminative between the HFA/AS group and the healthy control group. The neuropsychological profile of adult HFA/AS patients diagnosed late in life is compatible with that of previously investigated HFA/AS populations. These findings show that such basic autism-associated deficits persist until

    Pain-related temporomandibular disorders (TMDs) are the most prevalent conditions among TMDs. There is contrasting evidence available for association of pain-related TMD and masticatory muscle activity (MMA). The present investigation assesses the associations between MMA levels of masseter and temporalis muscles during awake and sleep among pain-related TMD diagnostic groups. The department of Oral Diagnostic Sciences, University at Buffalo. Twenty females and six males participated in this study. Using the diagnostic criteria for temporomandibular disorders (DC-TMDs), participants were diagnostically categorized. Subjects used a custom monitoring system, which recorded infield muscle activities. A factorial model tested for association between independent variable (muscle, time period, MMA level, and diagnostic group) effects and the logarithm of MMA. Greenhouse-Geisser test was used to determine any statistically significant associations (p≤0.003). No statistically significant association was found between four-way, three-way, and two-way analyses. However, among the main effects, range of magnitudes was the only variable to be statistically significant. Although the data suggest a trend of increased masseter MMA in the pain-related TMD diagnoses group both during awake and sleep time periods, such observation is not maintained for the temporalis muscle. In addition, temporalis MMA was found to be higher in the pain-related TMD diagnoses group only at extreme activity levels (<25 and ≥80% ranges). This data support the association between masticatory muscle hyperactivity and painful TMD conditions. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Dementia is characterised by cognitive deterioration and the manifestation of psychological and behavioural symptoms, especially changes in perception, thought content, mood, and conduct. In addition to drug therapy, non-pharmacological treatments are used to manage these symptoms, and one of these latter treatments is music therapy. Since this novel technique in non-verbal, it can be used to treat patients with dementia at any stage, even when cognitive deterioration is very severe. Patients' responses to music are conserved even in the most advanced stages of the disease DEVELOPMENT: A literature research was carried out using the following databases: Academic Search Complete, PubMed, Science Direct y Dialnet. The period of publication was 2003 to 2013 and the search keywords were 'Music Therapy, Dementia, Behaviour, Behaviour Disorders y Behavioural Disturbances'. Out of the 2188 studies that were identified, 11 studies met inclusion criteria for the systematic review. Music therapy is beneficial and improves behavior disorders, anxiety and agitation in subjects diagnosed with dementia. Copyright © 2014 Sociedad Española de Neurología.

    This descriptive study examines hypertension diagnostic practices in Utah primary care clinics relative to the 2015 US Preventive Services Task Force (USPSTF) recommendations for the accurate diagnosis of hypertension. We assessed clinic procedures in place to facilitate accurate in-office and out-of-office blood pressure (BP) measurement. An online questionnaire was administered to 321 primary care clinics. We compared current clinic BP measurement practices with the USPTF recommendations and assessed the level of adherence to the recommendations by level of clinic integration with a hospital. Of the 321 primary care clinics that received the assessment, 123 (38.3%) completed the questionnaire. Clinics varied significantly in their ability to provide accurate in-office measurement, ranging from 57.5% to 93.5% of clinics complying with USPSTF recommendations. Only 25.2% of clinics reported having access to ambulatory monitoring and 36.6% had instructional materials for accurate home BP monitoring. Clinics integrated with a hospital were more likely to report adherence to recommendations than solo or independent clinics (36.4% vs 10.5%; P primary care clinics are not well prepared to implement the USPSTF guidelines for accurate diagnosis of hypertension. Most office practices will benefit from support to develop their capacities. © Copyright 2017 by the American Board of Family Medicine.

    Cognitive effort is an essential part of both forensic and clinical decision-making. Errors occur in both fields because the cognitive process is complex and prone to bias. We performed a selective review of full-text English language literature on cognitive bias leading to diagnostic and forensic errors. Earlier work (1970-2000) concentrated on classifying and raising bias awareness. Recently (2000-2016), the emphasis has shifted toward strategies for "debiasing." While the forensic sciences have focused on the control of misleading contextual cues, clinical debiasing efforts have relied on checklists and hypothetical scenarios. No single generally applicable and effective bias reduction strategy has emerged so far. Generalized attempts at bias elimination have not been particularly successful. It is time to shift focus to the study of errors within specific domains, and how to best communicate uncertainty in order to improve decision making on the part of both the expert and the trier-of-fact. © 2017 American Academy of Forensic Sciences.

    Head trauma and concussion in football players have recently received considerable media attention. Postmortem evidence suggests that accrual of damage to the brain may occur with repeated blows to the head, even when the individual blows fail to produce clinical symptoms. There is an urgent need for improved detection and characterization of head trauma to reduce future injury risk and promote development of new therapies. In this study we examined neurological performance and health in the presence of head collision events in high school football players, using longitudinal measures of collision events (the HIT(™) System), neurocognitive testing (ImPACT(™)), and functional magnetic resonance imaging MRI (fMRI). Longitudinal assessment (including baseline) was conducted in 11 young men (ages 15-19 years) participating on the varsity and junior varsity football teams at a single high school. We expected and observed subjects in two previously described categories: (1) no clinically-diagnosed concussion and no changes in neurological behavior, and (2) clinically-diagnosed concussion with changes in neurological behavior. Additionally, we observed players in a previously undiscovered third category, who exhibited no clinically-observed symptoms associated with concussion, but who demonstrated measurable neurocognitive (primarily visual working memory) and neurophysiological (altered activation in the dorsolateral prefrontal cortex [DLPFC]) impairments. This new category was associated with significantly higher numbers of head collision events to the top-front of the head, directly above the DLPFC. The discovery of this new category suggests that more players are suffering neurological injury than are currently being detected using traditional concussion-assessment tools. These individuals are unlikely to undergo clinical evaluation, and thus may continue to participate in football-related activities, even when changes in brain physiology (and potential brain

    Concussive head injuries have received much attention in the medical and public arenas, as concerns have been raised about the potential short- and long-term consequences of injuries sustained in sports and other activities. While many student athletes have required evaluation after concussion, the exact definition of concussion has varied among disciplines and over time. The authors used data gathered as part of a multiinstitutional longitudinal study of the biomechanics of head impacts in helmeted collegiate athletes to characterize what signs, symptoms, and clinical histories were used to designate players as having sustained concussions. Players on 3 college football teams and 4 ice hockey teams (male and female) wore helmets instrumented with Head Impact Telemetry (HIT) technology during practices and games over 2-4 seasons of play. Preseason clinical screening batteries assessed baseline cognition and reported symptoms. If a concussion was diagnosed by the team medical staff, basic descriptive information was collected at presentation, and concussed players were reevaluated serially. The specific symptoms or findings associated with the diagnosis of acute concussion, relation to specific impact events, timing of symptom onset and diagnosis, and recorded biomechanical parameters were analyzed. Data were collected from 450 athletes with 486,594 recorded head impacts. Forty-eight separate concussions were diagnosed in 44 individual players. Mental clouding, headache, and dizziness were the most common presenting symptoms. Thirty-one diagnosed cases were associated with an identified impact event; in 17 cases no specific impact event was identified. Onset of symptoms was immediate in 24 players, delayed in 11, and unspecified in 13. In 8 cases the diagnosis was made immediately after a head impact, but in most cases the diagnosis was delayed (median 17 hours). One diagnosed concussion involved a 30-second loss of consciousness; all other players retained

    Gut microbiome dysbiosis has been demonstrated in subjects with newly diagnosed and chronic inflammatory bowel disease (IBD). In this study we sought to explore longitudinal changes in dysbiosis and ascertain associations between dysbiosis and markers of disease activity and treatment outcome. We performed a prospective cohort study of 19 treatment-naïve pediatric IBD subjects and 10 healthy controls, measuring fecal calprotectin and assessing the gut microbiome via repeated stool samples. Associations between clinical characteristics and the microbiome were tested using generalized estimating equations. Random forest classification was used to predict ultimate treatment response (presence of mucosal healing at follow-up colonoscopy) or non-response using patients' pretreatment samples. Patients with Crohn's disease had increased markers of inflammation and dysbiosis compared to controls. Patients with ulcerative colitis had even higher inflammation and dysbiosis compared to those with Crohn's disease. For all cases, the gut microbial dysbiosis index associated significantly with clinical and biological measures of disease severity, but did not associate with treatment response. We found differences in specific gut microbiome genera between cases/controls and responders/non-responders including Akkermansia, Coprococcus, Fusobacterium, Veillonella, Faecalibacterium, and Adlercreutzia. Using pretreatment microbiome data in a weighted random forest classifier, we were able to obtain 76.5 % accuracy for prediction of responder status. Patient dysbiosis improved over time but persisted even among those who responded to treatment and achieved mucosal healing. Although dysbiosis index was not significantly different between responders and non-responders, we found specific genus-level differences. We found that pretreatment microbiome signatures are a promising avenue for prediction of remission and response to treatment.

    Diagnoses play an important role in treatment planning and monitoring, but extensive research has shown low agreement between clinician-generated diagnoses and those from structured diagnostic interviews. However, most prior studies of agreement have not used research diagnoses based on gold standard methods, and researchers need to identify characteristics of diagnostically challenging clients. This study examined agreement between youth diagnoses generated through the research-based LEAD (Longitudinal, Expert, and All Data) standard to clinician diagnoses. Participants were 391 families seeking outpatient community mental health services for youths ages 6-18 (39.1% female, 88.2% African American). Youths and parents completed research interviews and clinic diagnoses were extracted from clinic records. LEAD diagnoses synthesized results of the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime (KSADS-PL) and the youth's developmental, family, and psychiatric history. Agreement between the LEAD and chart diagnoses was low, not exceeding "poor" agreement for most diagnostic categories (κs = .10-.46, median = .37). Disagreement was largely driven by missed diagnoses, although clinicians also did assign extra diagnoses for some clients. Fewer diagnostic errors occurred when the youth's clinical picture was more clear (e.g., high or low symptom severity, lower comorbidity), when the youth was older, when the family was higher functioning, and when the parent had more depression. However, youth and family characteristics explained very little of the variability in diagnostic errors. RESULTS support the need to investigate strategies to improve clinician diagnostic accuracy.

    2013-01-01

    Dementia with Lewy Bodies (DLB) was initially identified and confirmed primarily by pathology, but is soon to be incorporated into the Diagnostic and Statistical Manual criteria as a clinical disease entity. Despite these advances over more than 20 years, current data suggest that the sensitivity of accurate clinical diagnosis of DLB is still very low, although there is mounting evidence that supportive features may increase diagnostic accuracy. Although DLB remains easy to identify pathologically with different cellular pathologies differentiating it from other dementia syndromes, pathological identification using only Lewy body pathology has been shown to be inaccurate due to overlap with patients without dementia symptoms. A number of studies now suggest that a combination of cellular pathologies, which include α-synuclein and β-amyloid deposition as well as dopamine denervation, assist with differentiating this dementia syndrome from others. The clinical and pathological overlap with the tauopathy of Alzheimer’s disease still remains to be clarified. To determine more robust and independent clinicopathological correlates from Alzheimer’s disease, longitudinal prospective studies, using specific clinical batteries on dementia patients reaching the proposed criteria for DLB, with post-mortem assessment of the multiple pathologies associated with dementia, are required. Identifying genetic causes for DLB is another approach to investigate the pathogenesis of DLB. However this approach has been hindered to date by difficulties with identifying DLB clinically. The use of novel techniques is likely to advance knowledge on the pathogenesis of DLB and assist with redefining clinical and pathologic diagnostic criteria. To achieve the goal of more accurate clinical diagnosis of DLB, breakthroughs are necessary on the pathogenesis of DLB. PMID:23398715

    Prevalence estimates of ankylosing spondylitis vary considerably, and there are few nationwide estimates. The present study aimed to describe the national prevalence of clinically diagnosed ankylosing spondylitis in Sweden, stratified according to age, sex, geographical, and socio-economic factors, and according to subgroups with ankylosing spondylitis-related clinical manifestations and pharmacological treatment. All individuals diagnosed with ankylosing spondylitis according to the World Health Organization International Classification of Disease codes, between 1967 and 2009, were identified from the National Patient Register. Data regarding disease manifestations, patient demographics, level of education, pharmacological treatment, and geographical region were retrieved from the National Patient Register and other national registers. A total of 11,030 cases with an ankylosing spondylitis diagnosis (alive, living in Sweden, and 16 to 64 years old in December 2009) were identified in the National Patient Register, giving a point prevalence of 0.18% in 2009. The prevalence was higher in northern Sweden, and lower in those with a higher level of education. Men had a higher prevalence of ankylosing spondylitis (0.23% versus 0.14%, P ankylosing spondylitis of 0.18%. It revealed phenotypical and treatment differences between the sexes, as well as geographical and socio-economic differences in disease prevalence.

    In order to analyze clinical characteristics like sex-and age-based onset frequency and onset region from vertebral disease cases, this study investigated total 1,291 cases of vertebral disease that were diagnosed via magnetic resonance imaging (MRI) from January to December 2004 at B University Hospital in metropolitan area. For higher diagnostic accuracy in cases of spinal disorder diagnosed, this study analyzed findings from data reading conducted by veteran specialists in diagnostic radiology. But this study excluded uncertain lesion cases, the cases requiring differential diagnosis from other disorders and so on from subjects under analysis. This study employed superconductive 1.5 Tesla SIGNA MR/i for MRI test and basically received resulting images via FSE (fast spin echo). In particular, this study obtained T1 and T2 myelogram with regard to regional characteristics (such as cervical vertebrae, thoracic vertebrae and lumbar vertebra) and imaging characteristics for sagittal and transverse section. As a result, this study came to the following conclusions: 1. In terms of general characteristics of subjects under analysis, male group comprised 53.5% and female 46.5% out of total 1,291 subjects. 2. The regional onset frequency of spinal disorders was converged primarily on lumbar vertebra (65.5%), which was followed by cervical vertebrae (27.3%) and thoracic vertebrae (7.0%) respectively. 3. Top 10 cases with high onset frequency of spinal disorders can be listed as follows: 1) posterior bulging disc 65.8% 2) narrowing of neural foramen 23.8% 3) herniated intervertebral disc (HIVD) 22.4% 4) spinal stenosis 16.7% 5) osteochondrosis 6.4% 6) compression fracture 6.4% 7) facet joint arthropathy 6.2% 8) spondylolisthesis 6.0% 9) spinal cord tumor 3.5% 10) inter body fusion 2.6%.

Records of 123 psychiatrically referred children and adolescents with a Diagnostic and Statistical Manual of Mental Disorders, 4th ed., Text Revision (DSM-IV-TR) diagnosis of autistic disorder were examined. Mood disorder diagnoses and chief complaints along with family mood disorder history were the primary variables analyzed. Four subjects (3%) presented with depressed mood. Irritability complaints were frequent (n=78, 63%). Six subjects (5%) received a mood disorder diagnosis; all with mood disorder, not otherwise specified. No subjects received a depressive disorder diagnosis. Family history of mood disorders was common. Findings raise questions about the appropriate characterization and potential misdiagnoses of depression in youth with autistic disorder.

    Halitosis or bad breath is a taboo subject that is a widespread problem in the general population. Causes of bad breath can be multifactorial and long time sufferers can be marred from deep psychological stress. Because nine out of ten cases have an oral cause, the initial inquiry should be with a dentist. In a retrospective study from February 2003 to February 2010, the halitosis clinic at the University of Basel analyzed data from 465 patient medical histories. Study objectives evaluated the causes of halitosis, gender distribution and treatment success. All patients reported to have suffered from bad breath. However, 82.7% were actually diagnosed as having halitosis. Within this group, 96.2% showed an oral etiology and 3.8% showed an extra-oral cause. Women suffered significantly more from psychogenic halitosis. Success rates of 92.6% subjectively and 94.5% objectively reflect the treatment success of the diagnostic and therapeutic concepts presented at the University of Basel halitosis clinic over a seven year period.

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

    Background: Prior research suggests that 60-74% of males and 16-45% of females with fragile X syndrome (FXS) meet criteria for autism spectrum disorder (ASD) in research settings. However, relatively little is known about the rates of clinical diagnoses in FXS and whether such diagnoses are consistent with those performed in a research setting…

  12. Pain in the Blood? Envisioning Mechanism-Based Diagnoses and Biomarkers in Clinical Pain Medicine

    2015-03-01

    Full Text Available Chronic pain is highly prevalent, and pain medicine lacks objective biomarkers to guide diagnosis and choice of treatment. The current U.S. “opioid epidemic” is a reminder of the paucity of effective and safe treatment options. Traditional pain diagnoses according to the International Classification of Diseases are often unspecific, and analgesics are often prescribed on a trial-and-error basis. In contrast to this current state of affairs, the vision of future mechanism-based diagnoses of chronic pain conditions is presented in this non-technical paper, focusing on the need for biomarkers and the theoretical complexity of the task. Pain is and will remain a subjective experience, and as such is not objectively measurable. Therefore, the concept of “noci-marker” is presented as an alternative to “pain biomarker”, the goal being to find objective, measurable correlates of the pathophysiological processes involved in different chronic pain conditions. This vision entails a call for more translational pain research in order to bridge the gap between clinical pain medicine and preclinical science.

    Emergency medicine is a 'high risk' specialty. Some diseases develop suddenly and progress rapidly, and sudden unexpected deaths in the emergency department (ED) may cause medical disputes. We aimed to assess discrepancies between antemortem clinical diagnoses and postmortem autopsy findings concerning emergency medicine dispute cases and to figure out the most common major missed diagnoses. Clinical files and autopsy reports were retrospectively analysed and interpreted. Discrepancies between clinical diagnoses and autopsy diagnoses were evaluated using modified Goldman classification as major and minor discrepancy. The difference between diagnosis groups was compared with Pearson χ2 test. Of the 117 cases included in this study, 71 of cases (58 class I and 13 class II diagnostic errors) were revealed as major discrepancies (60.7%). The most common major diagnoses were cardiovascular diseases (54 cases), followed by pulmonary diseases, infectious diseases and so on. The difference of major discrepancy between the diagnoses groups was significant (pclinical diagnoses and postmortem examinations exist in emergency medical disputes cases; acute aortic dissection and myocardial infarction are the most frequently major missed diagnoses that ED clinicians should pay special attention to in practice. This study reaffirmed the necessity and usefulness of autopsy in auditing death in EDs. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available Background One of the most important issues to diagnose mental disorders is the use of independent tools with similar results. Documented history is an important tool to diagnose diseases at each stage. The first and fundamental step in diagnosis is a comprehensive clinical interview. Objectives The current study aimed to investigate the concordance of mental disorders diagnosed by psychiatrist’s clinical interviews and results of thematic apperception test (TAT conducted by psychologists. Methods It was a cross sectional descriptive-analytical study. The study population included the patients (male and female admitted in psychiatry section of Dr. Fatemi hospital in Ardabil, Iran, during 2009-2010. Data were collected from the archive of Ardebil Dr. Fatemi hospital and about 1200 patients were studied. Demographic data of participants including age, gender, marital status, admission date, discharge date and type of insurance were gathered from the recorded documents. The initial diagnosis of psychologist using TAT test was compared with the final diagnosis recorded for the patient attended by physicians. Data were analyzed using SPSS software, ver. 16. Results Out of 1,200 participants, 660 (55% were male and 540 (45% female; 150 (12.5% subjects were under 25 years old and 284 (23.66% were over 45 years old. Also, 650 subjects were illiterate and the rest were literate. The results of Chi-square test showed a significant difference between diagnoses of psychiatrist's clinical interviews with TAT results conducted by psychologists (P < 0.045. In spite of this difference, the results of TAT test were in relative concordance with psychiatrists' diagnoses for schizophrenia, depression, bipolar depression and anxiety disease. Conclusions The findings showed a relative concordance between psychiatric interviews and psychological assessments in the clinical diagnosis of mental illness.

Depending on the very nail structure involved, different clinical nail alterations can be observed. Irritation of the apical matrix results in psoriatic pits, mid-matrix involvement may cause leukonychia, whole matrix affection may lead to red lunulae or severe nail dystrophy, nail bed involvement may cause salmon spots, subungual hyperkeratosis, and splinter hemorrhages, and psoriasis of the distal nail bed and hyponychium causes onycholysis whereas that of the proximal nail fold causes psoriatic paronychia. The more extensive the involvement, the more severe is the nail destruction. Pustular psoriasis may be seen as yellow spots under the nail or, in case of acrodermatitis continua suppurativa, as an insidious progressive loss of the nail organ. Nail psoriasis has a severe impact on quality of life and may interfere with professional and other activities. Management includes patient counseling, avoidance of stress and strain to the nail apparatus, and different types of treatment. Topical therapy may be tried but is rarely sufficiently efficient. Perilesional injections with corticosteroids and methotrexate are often beneficial but may be painful and cannot be applied to many nails. All systemic treatments clearing widespread skin lesions usually also clear the nail lesions. Recently, biologicals were introduced into nail psoriasis treatment and found to be very effective. However, their use is restricted to severe cases due to high cost and potential systemic adverse effects. Keywords: nail psoriasis, etiology, pathology, quality of life, impact, treatment

    Contradictory studies suggest that some neonatal factors may be associated with a pervasive developmental disorder (PDD) diagnosis, but limited data is available from longitudinal, prospective medical record assessments. The present hypothesis-testing longitudinal, case-control study evaluated birth characteristics among cases diagnosed with a PDD in comparison to controls by examining prospectively collected automated medical records within the Vaccine Safety Datalink (VSD) database. Cases were Health Maintenance Organization (HMO)-enrolled from birth until diagnosed with International Classification of Disease, 9th revision (ICD-9) PDD (299.xx) and controls were HMO-enrolled from birth for at least 4.75 years without a PDD diagnosis. The birth characteristics examined included: gender, gestational age in weeks at birth, mean birth weight in grams, Appearance-Pulse-Grimace-Activity-Respiration (APGAR) scores at 1 minute and 5 minutes, and maternal age in years at birth. Cases had a significantly increased male/female ratio relative to controls. By contrast, mean gestational age at birth, mean birth weight, mean maternal age at birth, and mean APGAR scores at 1 minute and 5 minutes were not statistically different among cases compared to controls. This study indicates that cases diagnosed with a PDD as compared to controls do not have significant differences in neonatal factors.

    2011-01-01

    Background Diabetes mellitus is a chronic disease that can result in various medical, psychological and sexual dysfunctions (SD) if not properly managed. SD in men is a common under-appreciated complication of diabetes. This study assessed the prevalence and determinants of SD among diabetic patients in Tema, Greater Accra Region of Ghana. Method Sexual functioning was determined in 300 consecutive diabetic men (age range: 18-82 years) visiting the diabetic clinic of Tema General Hospital with the Golombok Rust Inventory of Sexual Satisfaction (GRISS) questionnaire, between November, 2010 and March, 2011. In addition to the socio-demographic characteristics of the participants, the level of glycosylated haemoglobin, fasting blood sugar (FBS) and serum testosterone were assessed. All the men had a steady heterosexual relationship for at least 2 years before enrolment in the study. Results Out the 300 participants contacted, the response rate was 91.3% after 20 declined participation and 6 incomplete data were excluded All the respondents had at least basic education, 97.4% were married, 65.3% were known hypertensive, 3.3% smoked cigarettes, 27% took alcoholic beverages and 32.8% did some form of exercise. The 69.3% SD rate observed in this study appears to be related to infrequency (79.2%), non-sensuality (74.5%), dissatisfaction with sexual acts (71.9%), non-communication (70.8%) and impotence (67.9%). Other areas of sexual function, including premature ejaculation (56.6%) and avoidance (42.7%) were also substantially affected. However, severe SD was seen in only 4.7% of the studied population. The perceived "adequate", "desirable", "too short" and "too long intra-vaginal ejaculatory latency time (IELT) are 5-10, 5-10, 1-2 and 15-30 minutes respectively. Testosterone correlates negatively with glycated haemoglobin (HBA1c), FBS, perceived desirable, too short IELT, and weight as well as waist circumference. Conclusion SD rate from this study is high but similar to

    Full Text Available Abstract Background Nonalcoholic fatty liver disease (NAFLD is the most frequent disease associated with abnormal liver tests that is characterized by a wide spectrum of liver damage, ranging from simple macro vesicular steatosis to steatohepatitis (NASH, cirrhosis or liver carcinoma. Liver biopsy is the most precise test to differentiate NASH from other stages of NAFLD, but it is an invasive and expensive method. This study aimed to create a clinical laboratory score capable of identify individual with NASH in severely obese patients submitted to bariatric surgery. Methods The medical records from 66 patients submitted to gastroplasty were reviewed. Their chemistry profile, abdominal ultrasound (US and liver biopsy done during the surgical procedure were analyzed. Patients were classified into 2 groups according to liver biopsy: Non-NASH group - those patients without NAFLD or with grade I, II or III steatosis; and NASH group - those with steatohepatitis or fibrosis. The t-test was used to compare each variable with normal distribution between NASH and Non-NASH groups. When comparing proportions of categorical variables, we used chi-square or z-test, where appropriate. A p-value Results 83% of patients with obesity grades II or III showed NAFLD, and the majority was asymptomatic. Total Cholesterol (TC≥200 mg/dL, alanine aminotransferase (ALT ≥30, AST/ALT ratio (AAR≤ 1, gammaglutaril-transferase (γGT≥30 U/L and abdominal US, compatible with steatosis, showed association with NASH group. We proposed 2 scores: Complete score (TC, ALT, AAR, γGT and US and the simplified score, where US was not included. The combination of biochemical and imaging results improved accuracy to 84.4% the recognition of NASH (sensitivity 70%, specificity 88.6%, NPV 91.2%, PPV 63. 6%.

    Full Text Available Background Fulfilling the learners' "real needs" will improve medical education. There are subjects that are necessary for any clinical residents not considering their field of specialty. Among the subjects ten seems to be the most important: research methodology and data analysis, computer-based programs, medical recording, cardiopulmonary and cerebral resuscitation, clinical teaching programs, communication skills, clinical ethics, laboratory examinations, reporting special diseases and death certification, and prescription. Purpose This cross-sectional study assessed educational needs of clinical residents for ten educational subjects. Methods A questionnaire prepared by board faculty members consisted of 10 close-ended questions, and one open­ ended question was distributed among 1307 residents from 22 clinical disciplines, who registered for preboard or promotion exam in June 2000. Results Among the subjects three were the most needed: computer-based programs 149 (60%, data collecting system 606 (49%, and clinical ethics 643 (46%. The prescription standard was the least required 177(13%. Conclusion Complementary training courses on these subjects can be an answer to the clinical residents needs.

    OBJECTIVE: The goal of this article was to describe the clinical characteristics and outcomes of patients diagnosed with psychogenic nonepileptic seizures (PNES). METHODS: We conducted a retrospective review of patients diagnosed with PNES in a 5-year period. RESULTS: Fifty patients with PNES were identified, giving an estimated incidence of 0.91\\/100,000 per annum. Thirty-eight were included for review, 15 of whom were male (39%). Eighteen patients had been diagnosed with epilepsy as well as PNES (47%). We demonstrated a gender difference in our patients, with males having higher seizure frequencies, more antiepileptic drug use, and a longer interval before diagnosis of PNES. Females were diagnosed with other conversion disorders more often than males. Impaired social function was observed in PNES, as was resistance to psychological interventions with a subsequent poor response to treatments. CONCLUSIONS: PNES remains a difficult condition to treat, and may affect males in proportions higher than those described in previous studies.

    2016-07-01

    Full Text Available BACKGROUND Acute appendicitis remains the most common cause of acute abdomen requiring surgical intervention. Diagnosis of appendicitis is done on clinical grounds. The aetiology and pathogenesis of appendicitis are poorly understood. The cause of pain in the cases with clinical diagnosis of acute appendicitis but intraoperatively normal looking appendix remains controversial. The present study aims at determining the cause of pain in these cases by combining routine histopathology, IHC to investigate the status of the enteric nervous system in normal and inflamed appendices. MATERIALS AND METHODS In the present study, 694 patients who underwent appendicectomy with diagnosis of acute appendicitis were included. In 89 cases, there were no signs of inflammation intraoperatively. These appendix specimens were followed by histopathological examination by H&E staining. 69 out of 89 specimens did not have signs of inflammation in histological examination by H&E staining. Cases which are diagnosed as acute appendicitis but histologically negative in H&E staining are taken as study cases. 49 acute appendicitis cases- histologically positive acute appendicitis (HPAA and 20 appendices from right hemicolectomy specimens were taken as controls. All these specimens were subjected to; 1 Routine Haematoxylin & Eosin staining. 2 Toluidine blue stain for mast cell evaluation. 3 Immunohistochemistry by S-100 stain for evaluating size and number of the ganglia. OBSERVATION The mean mast cell count was more in the histologically negative acute appendicitis group when compared to histologically positive acute appendicitis and control group. The mean size and number of the ganglia were more in the histologically negative acute appendicitis group when compared to histologically positive acute appendicitis and control groups. CONCLUSION Neuronal hypertrophy and mast cells may play a role in the pathogenesis of “appendicitis like pain” in patients with

    Diabetes mellitus and periodontitis are complex chronic diseases with an established bidirectional relationship. This systematic review evaluated in subjects with professionally diagnosed periodontitis the prevalence and odds of having diabetes. The MEDLINE-PubMed, CENTRAL and EMBASE databases were searched. Prevalence of diabetes mellitus among subjects with periodontitis were extracted or if possible calculated. From the 803 titles and abstracts that came out of the search, 29papers met the initial criteria. Prevalence of diabetes was 9.4% among subjects with periodontitis and 12.8%among subjects without periodontitis. Based on sub-analysis, for subjects with periodontitis, the prevalence of diabetes was 6.5%when diabetes was self-reported, compared to 17.3%when diabetes was clinically assessed. The highest prevalence of diabetes among subjects with periodontitis was observed in studies originating from Asian countries(17.2%,n=16647) and the lowest in studies describing populations from Europe(4.3%(n=7858). The overall odds ratio for diabetes patients to be among subjects with periodontitis as compared to those without periodontitis was 2.59(95%CI[2.12;3.15]). A substantial variability in the definitions of periodontitis, combination of self-reported and clinically assessed diabetes, lack of confounding for diabetes control in included studies introduces estimation bias. The overall prevalence and odds of having diabetes is higher within periodontitis populations compared to people without periodontitis. Self-reported diabetes underestimates the prevalence when compared to this condition assessed clinically. Geographical differences were observed: the highest diabetes prevalence among subjects with periodontitis was observed in studies conducted in Asia and the lowest in studies originating from Europe.

    Emerging evidence points to proteoglycan abnormalities in the pathophysiology of schizophrenia (SZ). In particular, markedly abnormal expression of chondroitin sulfate proteoglycans (CSPGs), key components of the extracellular matrix, was observed in the medial temporal lobe. CSPG functions, including regulation of neuronal differentiation and migration, are highly relevant to the pathophysiology of SZ. CSPGs may exert similar functions in the olfactory epithelium (OE), a continuously regenerating neural tissue that shows cell and molecular abnormalities in SZ. We tested the hypothesis that CSPG expression in OE may be altered in SZ. CSPG-positive cells in postmortem OE from non-psychiatric control (n=9) and SZ (n=10) subjects were counted using computer-assisted light microscopy. 'Cytoplasmic' CSPG (c-CSPG) labeling was detected in sustentacular cells and some olfactory receptor neurons (c-CSPG+ORNs), while 'pericellular' CSPG (p-CSPG) labeling was found in basal cells and some ORNs (p-CSPG+ORNs). Dual labeling for CSPG and markers for mature and immature ORNs suggests that c-CSPG+ORNs correspond to mature ORNs, and p-CSPG+ORNs to immature ORNs. Previous studies in the same cohort demonstrated that densities of mature ORNs were unaltered (Arnold et al., 2001). In the present study, numerical densities of c-CSPG+ORNs were significantly decreased in SZ (p<0.025; 99.32% decrease), suggesting a reduction of CSPG expression in mature ORNs. Previous studies showed a striking increase in the ratios of immature neurons with respect to basal cells. In this study, we find that the ratio of p-CSPG+ORNs/CSPG+basal cells was significantly increased (p=0.03) in SZ, while numerical density changes of p-CSPG+ORNs (110.71% increase) or CSPG+basal cells (53.71% decrease), did not reach statistical significance. Together, these results indicate that CSPG abnormalities are present in the OE of SZ and specifically point to a reduction of CSPG expression in mature ORNs in SZ. Given the

    Clinical testing of nanomedicines presents two challenges to prevailing, human subject-centered frameworks governing research ethics. First, some nanomedical applications may present risk to persons other than research subjects. Second, pressures encountered in testing nanomedicines may present threats to the kinds of collaborations and collective activities needed for supporting clinical translation and redeeming research risk. In this article, I describe how similar challenges were encountered and addressed in gene transfer, and sketch policy options that might be explored in the nanomedicine translation arena. © 2012 American Society of Law, Medicine & Ethics, Inc.

    The study aimed to examine the clinical correlates of polysubstance dependence. Seven hundred and fifty two substance-dependent subjects were interviewed with the Mini-International Neuropsychiatric Interview, the Brown-Goodwin Assessment for Lifetime History of Aggression (BGLHA), and the Hamilton Depression Rating Scale (HDRS). Subjects completed the Childhood Trauma Questionnaire (CTQ), Eysenck Personality Questionnaire (EPQ), and Barratt Impulsivity Scale (BIS). Subjects found to have polysubstance dependence were compared with subjects with monosubstance dependence. Polysubstance dependence was found in 48.3% of the subjects. Subjects with polysubstance dependence were significantly younger, more were separated/divorced and unemployed, and they had significantly higher CTQ scores for childhood emotional and physical neglect, higher EPQ psychoticism scores, higher BGLHA aggression scores, and higher BIS impulsivity scores. Significantly more of the polysubstance dependent subjects had attempted suicide, self-mutilated, and exhibited aggressive behavior. Significantly more monosubstance dependent subjects had an Axis I psychiatric disorder and they had higher HDRS depression scores. Polysubstance dependence is common among the groups studied and may be associated with certain socio-demographic, developmental, and personality factors.

    Full Text Available Abstract Background The objective of this paper is to estimate the amount of cost-savings to the Australian health care system from implementing an evidence-based clinical protocol for diagnosing emergency patients with suspected pulmonary embolism (PE at the Emergency department of a Victorian public hospital with 50,000 presentations in 2001–2002. Methods A cost-minimisation study used the data collected in a controlled clinical trial of a clinical protocol for diagnosing patients with suspected PE. Thenumber and type of diagnostic tests in a historic cohort of 185 randomly selected patients, who presented to the emergency department with suspectedPE during an eight month period prior to the clinical trial (January 2002 -August 2002 were compared with the number and type of diagnostic tests in745 patients, who presented to the emergency department with suspected PE from November 2002 to August 2003. Current Medicare fees per test were usedas unit costs to calculate the mean aggregated cost of diagnostic investigation per patient in both study groups. A t-test was used to estimate the statistical significance of the difference in the cost of resources used for diagnosing PE in the control and in the intervention group. Results The trial demonstrated that diagnosing PE using an evidence-based clinical protocol was as effective as the existing clinical practice. The clinical protocol offers the advantage of reducing the use of diagnostic imaging, resulting in an average cost savings of at least $59.30 per patient. Conclusion Extrapolating the observed cost-savings of $59.30 per patient to the wholeof Australia could potentially result in annual savings between $3.1 million to $3.7 million.

    Epidemiological evaluations of the prevalence of asthma are usually based on written questionnaires (WQs) in combination with validation by clinical investigation. In the present investigation, we compared parental assessment of asthma among their preschool children in response to a WQ...... clinics in the same region, were analysed in parallel. Finally, a complementary WQ was sent to the parents of children identified as asthmatic by either or both of this approaches. In response to the WQ 5.9% were claimed to suffer from asthma diagnosed by a doctor. According to the medical records...... with the corresponding medical records in the same region. An International Study of Asthma and Allergies in Childhood (ISAAC)-based WQ was answered by 75% of the parents of 6295 children aged 1-6 yr.

    Full Text Available Objectives: There is an overlap regarding Pittsburgh compound B (PIB retention in patients clinically diagnosed as Alzheimer's disease (AD and non-AD dementia. The aim of the present study was to investigate whether there are any differences between PIB-positive and PIB-negative patients in a mixed cohort of patients with neurodegenerative dementia of mild severity regarding neuropsychological test performance and regional cerebral glucose metabolism measured with [18F]fluoro-2-deoxy-D-glucose (FDG positron emission tomography (PET. Methods: Eighteen patients clinically diagnosed as probable AD or frontotemporal dementia were examined with PIB PET, FDG PET and neuropsychological tests and followed for 5-9 years in a clinical setting. Results: The PIB-positive patients (7 out of 18 had slower psychomotor speed and more impaired visual episodic memory than the PIB-negative patients; otherwise performance did not differ between the groups. The initial clinical diagnoses were changed in one third of the patients (6 out of 18 during follow-up. Conclusions: The subtle differences in neuropsychological performance, the overlap of hypometabolic patterns and clinical features between AD and non-AD dementia highlight the need for amyloid biomarkers and a readiness to re-evaluate the initial diagnosis.

  18. Clinical characteristics and distinctiveness of DSM-5 eating disorder diagnoses: findings from a large naturalistic clinical database

    2013-01-01

    Background DSM-IV eating disorder (ED) diagnoses have been criticized for lack of clinical utility, diagnostic instability, and over-inclusiveness of the residual category “ED not otherwise specified” (EDNOS). Revisions made in DSM-5 attempt to generate a more scientifically valid and clinically relevant system of ED classification. The aim with the present study was to examine clinical characteristics and distinctiveness of the new DSM-5 ED diagnoses, especially concerning purging disorder (PD). Methods Using a large naturalistic Swedish ED database, 2233 adult women were diagnosed using DSM-5. Initial and 1-year follow-up psychopathology data were analyzed. Measures included the Eating Disorder Examination Questionnaire, Structural Eating Disorder Interview, Clinical Impairment Assessment, Structural Analysis of Social Behavior, Comprehensive Psychiatric Rating Scale, and Structured Clinical Interview for DSM-IV Axis I Disorders. Results Few meaningful differences emerged between anorexia nervosa binge/purge subtype (ANB/P), PD, and bulimia nervosa (BN). Unspecified Feeding and Eating Disorders (UFED) showed significantly less severity compared to other groups. Conclusions PD does not appear to constitute a distinct diagnosis, the distinction between atypical AN and PD requires clarification, and minimum inclusion criteria for UFED are needed. Further sub-classification is unlikely to improve clinical utility. Instead, better delineation of commonalities is important. PMID:24999410

    The purpose of the study was to identify key nursing diagnoses with related factors and signs/symptoms using NANDA-I for patients with heart failure (HF). A retrospective descriptive design was used to address the research questions. Data were obtained from the records of patients discharged for 1 year with the medical diagnoses of HF from a Midwestern community hospital. A total of 272 inpatient records were analyzed to describe the frequency and percentage of NANDA-I diagnosis with related factors and signs/symptoms. The top 10 NANDA-I diagnoses associated with related factors and signs/symptoms were identified. Further research related to standardized nursing terminologies such as NANDA-I using large clinical databases from health information systems is needed to support evidence-based nursing diagnosis decision making. © 2015 NANDA International, Inc.

    To analyze the knowledge related to the use of the Rasch model in validation of nursing diagnoses. Integrative literature review with search in LILACS, PUBMED, CINAHL, and SCOPUS. Five studies comprised the sample, which analyzed unidimensionality, local independence, item calibration, item reliability, separation of items and people, and differential item functioning for analyzing nursing diagnoses. The Rasch model seems to be a useful method to validate nursing diagnoses and probably also for the validation of nursing outcomes in the Nursing Outcomes Classification. The use of this model is promising, considering the advantages that it can be used in studies with several methodological designs. Methods that are able to provide more robust evidence of nursing diagnosis validity are needed to support highly accurate diagnostic findings in clinical practice. © 2016 NANDA International, Inc.

    Improper inhaler use results in decreased drug deposition in the lungs. The impact of health literacy and poor vision on the patient's ability to learn inhaler technique by reading instructions has not been confirmed. This study evaluated the effectiveness of learning inhaler technique from written instructions and the impact of health literacy for patients diagnosed with COPD who used a dry powder inhaler (DPI). This pilot study recruited subjects diagnosed with COPD. A trained assessor scored subjects' inhaler technique before and after reading the appropriate American College of Chest Physicians handouts. Peak inspiratory flows (PIFs) were measured using an InCheck Dial. Health literacy was measured by the S-TOFHLA (Short Test of Functional Health Literacy in Adults), and visual acuity was measured by a Snellen chart. Associations between health literacy and visual acuity and changes in subjects' inhaler technique scores were assessed by Spearman's rho. Inhaler technique change scores were assessed by the Wilcoxon signed-rank test at P = .05. Of the 24 participants enrolled, 63% were female, mean age was 65.6 y, and 83% were Global Initiative for Chronic Obstructive Lung Disease air-flow limitation 2 or 3. Wilcoxon scores were significant for improved total scores for both the Diskus and HandiHaler, with medians improving from 6.5 to 7.0 (interquartile range 6.0-7.8) (P = .047) and from 6.0 to 7.5 (interquartile range 7.0-9.0) (P = .002), respectively. The minimum required PIF was achieved by 93.8% of the Diskus and 94.4% of the HandiHaler groups. There were no associations detected between the handout intervention (Diskus and HandiHaler) and health literacy level and vision. The educational handouts for DPIs helped participants already using a DPI to improve their inhaler technique. Stable participants diagnosed with COPD are able to generate appropriate PIFs to properly use DPIs. Neither vision nor health literacy was associated with the inability to learn

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

    Directory of Open Access Journals (Sweden)

    Adalberto Studart Neto

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

    Diagnosis information from existing data sources is used commonly for epidemiologic, administrative, and research purposes. The quality of such data for emergency department (ED) visits is unknown. To determine the agreement on final diagnoses between two sources, electronic administrative sources and manually abstracted medical records, for pediatric ED visits, in a multicenter network. This was a cross sectional study at 19 EDs nationwide. The authors obtained data from two sources at each ED during a three-month period in 2003: administrative sources for all visits and abstracted records for randomly selected visits during ten days over the study period. Records were matched using unique identifiers and probabilistic linkage. The authors recorded up to three diagnoses from each abstracted medical record and up to ten for the administrative data source. Diagnoses were grouped into 104 groups using a modification of the Clinical Classification System. A total of 8,860 abstracted records had at least one valid diagnosis code (with a total of 12,895 diagnoses) and were successfully matched to records in the administrative source. Overall, 67% (95% confidence interval = 66% to 68%) of diagnoses from the administrative and abstracted sources were within the same diagnosis group. Agreement varied by site, ranging from 54% to 77%. Agreement varied substantially by diagnosis group; there was no difference by method of linkage. Clustering clinically similar diagnosis groups improved agreement between administrative and abstracted data sources. ED diagnoses retrieved from electronic administrative sources and manual chart review frequently disagree, even if similar diagnosis codes are grouped. Agreement varies by institution and by diagnosis. Further work is needed to improve the accuracy of diagnosis coding; development of a grouping system specific to pediatric emergency care may be beneficial.

    Type 2 diabetes is associated with serious complications and shortens life. Its prevalence is increasing rapidly worldwide and no cure is available. One logical response is to diagnose the condition as early as possible. Clinical opportunistic screening is one mechanism for making the diagnosis before symptoms are reported. This paper reports the cost of using this technique in UK general practice. In one UK general practice, the electronic medical records were searched to determine the number of blood glucose and oral glucose tolerance tests undertaken for non-pregnant adults without known diabetes over three consecutive years. The laboratory, staff and administrative costs associated with these screening tests were calculated. The records of all patients newly diagnosed with Type 2 diabetes during the same period were reviewed to identify diagnoses made by clinical opportunistic screening. Total costs were divided by the number of diagnoses to determine a cost per diagnosis detected by opportunistic screening. During the study period, 5720 screening tests were conducted for 2763 patients. Over the 3 years, 86 patients were diagnosed with Type 2 diabetes, 54 (63%) via screening (yield 2.0%; number needed to screen 51.2). The screening costs totalled £ 20,372. The average cost per new screen-detected diagnosis was £ 377. Almost two-thirds of new cases of Type 2 diabetes can be detected before symptoms are reported, at reasonable cost by opportunistic screening in general practice, without the use of extra resources. As an affordable alternative to population screening, clinical opportunistic screening merits further consideration. © 2012 The Authors. Diabetic Medicine © 2012 Diabetes UK.

    Full Text Available Lateral hip snapping is a nosological entity that is often unknown to many orthopedists and even to some hip surgery specialists. It comprises palpable and/or audible snapping on the lateral face of the hip that is sometimes painful, caused by muscle-tendon friction on the greater trochanter during flexion and extension of the coxofemoral joint. In the following, we describe a new test for diagnosing lateral hip snapping, which is eminently clinical.

    Benign paroxysmal positional vertigo (BPPV) may compromise the balance of elderly subjects. To observe the effects of the Epley maneuver in elderly subjects with BPPV and assess clinical and functional aspects of body balance. This is a prospective clinical study. Patients diagnosed with BPPV (Dix-Hallpike test) were submitted to the Timed Up & Go (TUG) test, the Clinical Test of Sensory Interaction and Balance (CTSIB), and lower limb testing before and after they were repositioned using the modified Epley maneuver. Most subjects were females, and the group's mean age was 70.10 years (SD = 7.00). All patients had canalithiasis of the posterior canal. The following symptoms improved after the maneuver: postural instability (p = 0.006), nausea and vomiting (p = 0.021), and tinnitus (p = 0.003). Subjects improved their times significantly in the TUG and lower limb tests after the Epley maneuver (p < 0.001). Patients performed better on the CTSIB after the Epley maneuver on condition 2 (p < 0.003), condition 3 (p < 0.001), condition 4 (p < 0.001), condition 5 (p < 0.001), and condition 6 (p < 0.001). Clinical and functional aspects of body balance in elderly with BPPV improved after treatment with the modified Epley maneuver.

  8. Constructing diagnostic likelihood: clinical decisions using subjective versus statistical probability.

    2017-07-01

    Although physicians are highly trained in the application of evidence-based medicine, and are assumed to make rational decisions, there is evidence that their decision making is prone to biases. One of the biases that has been shown to affect accuracy of judgements is that of representativeness and base-rate neglect, where the saliency of a person's features leads to overestimation of their likelihood of belonging to a group. This results in the substitution of 'subjective' probability for statistical probability. This study examines clinicians' propensity to make estimations of subjective probability when presented with clinical information that is considered typical of a medical condition. The strength of the representativeness bias is tested by presenting choices in textual and graphic form. Understanding of statistical probability is also tested by omitting all clinical information. For the questions that included clinical information, 46.7% and 45.5% of clinicians made judgements of statistical probability, respectively. Where the question omitted clinical information, 79.9% of clinicians made a judgement consistent with statistical probability. There was a statistically significant difference in responses to the questions with and without representativeness information (χ2 (1, n=254)=54.45, pprobability. One of the causes for this representativeness bias may be the way clinical medicine is taught where stereotypic presentations are emphasised in diagnostic decision making.

    Diagnostic interviews are valuable tools for generating reliable and valid psychiatric diagnoses. However, little is known about the diagnostic effects of implementing such an interview into the standard diagnostic procedure of a child psychiatric clinic. Therefore, we reviewed discharge diagnoses of psychiatric patients (age: 8-12 years; combined sample of inpatients and day hospital patients) over two intervals before and after implementing the semi-structured diagnostic interview K-SADS-PL as a diagnostic tool during intake. Each interval was a two year period spanning from 2009-2010 (pre sample; n=177) and from 2012-2013 (post sample; n=132). The number of diagnoses per patient and the co-morbidity rate increased significantly in the post sample. Furthermore, the percentage of children with a nonspecific diagnosis "other mixed disorders of conduct and emotions" (ICD-10: F92.8) decreased significantly after using the K-SADS-PL. Regarding the main diagnostic categories, a significant increase in the number of anxiety disorders and stress-related and somatoform disorders was found in the post sample. The results suggest that implementing a semi-structured interview into the daily routine of child psychiatry may have a substantial impact on discharge diagnoses. Practical implications are discussed and ideas for future research are given. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  10. Disability and Comorbidity: Diagnoses and Symptoms Associated with Disability in a Clinical Population with Panic Disorder

    Directory of Open Access Journals (Sweden)

    Caroline A. Bonham

    2014-01-01

    Full Text Available Background. Anxiety disorders are associated with considerable disability in the domains of (1 work, (2 social, and (3 family and home interactions. Psychiatric comorbidity is also known to be associated with disability. Methods. Data from the Cross-National Collaborative Panic Study was used to identify rates of comorbid diagnoses, anxiety and depression symptom ratings, and Sheehan disability scale ratings from a clinical sample of 1165 adults with panic disorder. Results. Comorbid diagnoses of agoraphobia, major depression, and social phobia were associated with disability across the three domains of work, social, and family and home interactions. The symptom of agoraphobic avoidance makes the largest contribution to disability but there is no single symptom cluster that entirely predicts impairment and disability. Limitations. The findings about the relative contributions that comorbid diagnoses make to disability only apply to a population with panic disorder. Conclusions. Although panic disorder is not generally considered to be among the serious and persistent mental illnesses, when it is comorbid with other diagnoses, it is associated with considerable impairment. In particular, the presence of agoraphobic avoidance should alert the clinician to the likelihood of important functional impairment. When measuring the functional impact of comorbid anxiety disorders, both the categorical and the dimensional approaches to diagnosis make valuable contributions.

    Atrophy of specific, regional, and generalized brain structures occurs as a result of the Alzheimer's disease (AD) process. Comparing AD patients with histopathological confirmation of the disease at autopsy to those without autopsy but who were clinically diagnosed using the same antemortem criteria will provide further evidence of the utility and accuracy of neuropsychological assessments at the time of diagnosis, as well as the efficacy of quantitative magnetic resonance imaging (qMRI) in demonstrating gross neuropathological changes associated with the disease. The Cache County Study of Aging provides a unique opportunity to determine how closely AD subjects with only the clinical diagnosis match similarly diagnosed AD subjects but with postmortem confirmation of the disease. qMRI volumes of various brain structures, as well as neuropsychological outcome measures from an expanded battery, were obtained in 31 autopsy-confirmed AD subjects and 45 clinically diagnosed AD subjects. Of the various qMRI variables examined, only total temporal lobe volume was different, where those with postmortem confirmation had reduced volume. No significant differences between the two groups were found with any of the neuropsychological outcome measures. These findings confirm the similarity in neuroimaging and neuropsychological assessment findings between those with just the clinical diagnosis of AD and those with an autopsy-confirmed diagnosis in the moderate-to-severe stage of the disease at the time of diagnosis.

    In Egypt, data on the prevalence of chronic diabetic complications, which are essential for the adjustment of policies and practices related to diabetes care, are scarce. Therefore, the aim of this study was to determine the frequency of chronic complications of diabetes; namely neuropathy, diabetic kidney disease (DKD), retinopathy and peripheral arterial disease (PAD) in newly-diagnosed versus known type 2 diabetic patients. This is a cross-sectional study that is based on a previous household survey conducted on a representative sample of the population of Alexandria, Egypt. This study included 506 consecutive subjects with type 2 diabetes; 323 patients with previously known T2DM and 183 patients with newly diagnosed T2DM (discovered during the survey). For each participant, a focused history was taken. Comprehensive clinical examination was done including fundus examination, foot examination and assessment of ankle brachial index. Laboratory tests included HbAlc, lipids profile, serum creatinine and urinary albumin creatinine ratio (UACR). Peripheral neuropathy was detected in 20% of the studied patients; 29.4% of known patients and 3.3% of newly diagnosed patients (pDiabetic kidney disease was detected in 33.2% of the studied patients; 46.1% of known patients and 10.4% of newly diagnosed patients (pDiabetic retinopathy was detected in 34.6% of the studied patients; 48.3% of known patients and 10.4% of newly diagnosed patients (pdiabetes, the presence of any of the studied complications (neuropathy, diabetic kidney disease, retinopathy or PAD) was significantly associated with the presence of all other complications (pdiabetes, the presence of diabetic kidney disease was significantly associated with the presence of retinopathy (pdiabetes at the time of diagnosis.

    Although several models have been developed to predict the probability of Gleason sum upgrading between biopsy and radical prostatectomy specimens, most of these models are restricted to prostate-specific antigen screening-detected prostate cancer. This study aimed to build a nomogram for the prediction of Gleason sum upgrading in clinically diagnosed prostate cancer. The study cohort comprised 269 Chinese prostate cancer patients who underwent prostate biopsy with a minimum of 10 cores and were subsequently treated with radical prostatectomy. Of all included patients, 220 (81.8%) were referred with clinical symptoms. The prostate-specific antigen level, primary and secondary biopsy Gleason scores, and clinical T category were used in a multivariate logistic regression model to predict the probability of Gleason sum upgrading. The developed nomogram was validated internally. Gleason sum upgrading was observed in 90 (33.5%) patients. Our nomogram showed a bootstrap-corrected concordance index of 0.789 and good calibration using 4 readily available variables. The nomogram also demonstrated satisfactory statistical performance for predicting significant upgrading. External validation of the nomogram published by Chun et al. in our cohort showed a marked discordance between the observed and predicted probabilities of Gleason sum upgrading. In summary, a new nomogram to predict Gleason sum upgrading in clinically diagnosed prostate cancer was developed, and it demonstrated good statistical performance upon internal validation.

    Little is known today about the characteristics of individuals diagnosed with fibromyalgia, their degree of disability and the health system response system response to this condition. The objectives of this work include: to establish the sociodemographic, clinical and psychosocial profile of male and female patients with fibromyalgia. To describe the response they receive from the health service, and to study the repercussions of this syndrome on the daily activities of subjects who suffer it, including its effects on their work environment. Descriptive cross-sectional study. The information was received from telephone interviews of individuals diagnosed with fibromyalgia in the Hospital Universitario Virgen de las Nieves in Granada during 2003. 92.1% of those interviewed were women. Fibromyalgia caused work absenteeism in 31.4% of cases; and 64% regarded their health as poor or very poor. Fibromyalgia was associated with other diseases in 52.3% of cases. The family doctor is the specialist consulted before diagnosis in 92.1% of cases. A total of 50.5% had a history of psychiatric disorders, these were still present at the time of interview in 36.4%. Around 71% of the sample received family support, and 70.1% of cases considered the disease to seriously affect their environment. Fibromyalgia was mainly diagnosed in women. Subjects with this syndrome have a poor perception of their own health and work situation, and it negatively affects their family environment.

    Past research has shown discrepancies between the time of symptom onset for patients with acute coronary syndrome (ACS) as documented in the medical record (MR) and patients' recall of the time assessed through subject interviews done later by researchers. The aim of this study is to determine if there were differences between the time of symptom onset documented in the MR and subject interview taking into consideration sex, age group, and recall period for patients admitted to the emergency department for symptoms suggestive of ACS. A secondary analysis was conducted on data from the PROMOTION (Patient Response to Myocardial Infarction Following a Teaching Intervention Offered by Nurses) trial, a multicenter randomized clinical trial to reduce patient prehospital delay to treatment in ACS. Of the 3522 subjects with CAD enrolled into the trial, 3087 subjects completed 2-year follow-up. Of these, 331 subjects sought treatment in the emergency department for ACS symptoms and 276 patients (83%) had complete information on the time of symptom onset from both sources. Of the 276 patients, 25 (9%) had differing times more than 48 hours and were thus excluded. The median difference between the 2 sources was 45.0 minutes. When both times were examined, there were no significant differences in time by sex (P = .720) or by age group (P = .188). The median number of days between the interview and the date of symptom onset was 29.5 days. There was a significant correlation between differences in the time of symptom onset and the length of recall period (rs = 0.148, P = .023). In multivariable modeling, a longer recall period was associated with greater median differences in the symptom onset time (b = 13.2, P = .023). These results suggest that the time of symptom onset obtained at the time of the index event and documented in the MR is not interchangeable with data obtained later by research staff, especially if the interview is not conducted near the time of the index event.

The logistic regression analysis between the findings of MRI and the clinical features show that there was a significant association in the neural foramen or lateral recess (Odd's ratio 7.106, p<0.05, the root compression (p<0.01 as well as the disc extrusion (p<0.05. There was no statistical association between clinical levels and other MRI findings like disc protrusion and disc bulge (p value 0.21 and 0.14, respectively. The strength of agreement between clinical and MRI diagnosis level of disc prolapse was calculated using kappa statistics (k-value. The test revealed a very good agreement for L3/4 (k-value = 0.812 and good agreement for L4/5 and L5/SI  level (k-value 0.75 and 0.75 respectively between these two procedures, suggesting that level of disc prolapse could be correctly  diagnosed without MRI findings.  In conclusion, clinically diagnosed levels associate well with MRI levels, but all MRI abnormalities do not have any clinical significance.

    Object Concussive head injuries have received much attention in the medical and public arenas, as concerns have been raised about the potential short- and long-term consequences of injuries sustained in sports and other activities. While many student athletes have required evaluation after concussion, the exact definition of concussion has varied among disciplines and over time. The authors used data gathered as part of a multiinstitutional longitudinal study of the biomechanics of head impacts in helmeted collegiate athletes to characterize what signs, symptoms, and clinical histories were used to designate players as having sustained concussions. Methods Players on 3 college football teams and 4 ice hockey teams (male and female) wore helmets instrumented with Head Impact Telemetry (HIT) technology during practices and games over 2–4 seasons of play. Preseason clinical screening batteries assessed baseline cognition and reported symptoms. If a concussion was diagnosed by the team medical staff, basic descriptive information was collected at presentation, and concussed players were reevaluated serially. The specific symptoms or findings associated with the diagnosis of acute concussion, relation to specific impact events, timing of symptom onset and diagnosis, and recorded biomechanical parameters were analyzed. Results Data were collected from 450 athletes with 486,594 recorded head impacts. Forty-eight separate concussions were diagnosed in 44 individual players. Mental clouding, headache, and dizziness were the most common presenting symptoms. Thirty-one diagnosed cases were associated with an identified impact event; in 17 cases no specific impact event was identified. Onset of symptoms was immediate in 24 players, delayed in 11, and unspecified in 13. In 8 cases the diagnosis was made immediately after a head impact, but in most cases the diagnosis was delayed (median 17 hours). One diagnosed concussion involved a 30-second loss of consciousness; all other

    Amputation is commonly performed in an attempt to both treat and diagnose conditions affecting the digits of cats. The records of multiple veterinary diagnostic laboratories were searched to identify submissions of amputated digits from cats. Eighty-five separate submissions were reviewed for diagnosis, age, sex, limb of origin, and digits affected; and the original submitting clinics were surveyed to determine clinical outcome. The Kaplan-Meier product-limit method was used to determine the disease-free interval and survival time. Neoplastic disease was identified in 63 of 85 submissions, with exclusively inflammatory lesions composing the other 22 cases. In 60 (95.2%) of the neoplastic cases, a malignant tumor was identified. Squamous cell carcinoma was the most commonly identified malignant tumor (n = 15; 23.8%) and was associated with a median survival time of 73 days. Other diagnoses included fibrosarcoma (n = 14; 22.2%); adenocarcinoma, likely metastases of a primary pulmonary neoplasm (n = 13; 20.6%); osteosarcoma (n = 5; 7.9%); mast cell tumor (n = 4; 6.3%); hemangiosarcoma (n = 5; 7.9%); malignant fibrous histiocytoma (n = 2; 3.2%); giant cell tumor of bone (n = 2; 3.2%); and hemangioma (n = 2; 3.2%). Giant cell tumor of bone has not been previously described in the digits of cats. Various neoplasms can occur in the digits of cats, and submission of the amputated digit for histopathologic diagnosis is essential to determine the histogenesis and predict the clinical outcome.

    Full Text Available Objective: To analyze the clinical features of lung cancer diagnosed by bronchoscopy. Methods: The clinical features of 2168 patients with lung cancer diagnosed by bronchoscopy were retrospectively analyzed, including gender, age, pathological type, diseased region, manifestations under bronchoscopy and methods of drawing materials. Results: The ratio of male/female was 4.8:1 and the peak onset age was 60 - 69 years old. The major pathological type was squamous cell carcinoma (44.5%, then adenocarcinoma (25.9% and small cell lung cancer (18.3%. The incidence of squamous cell carcinoma was the highest in males (50.6%, while that of adenocarcinoma in females (56.2%. The positive diagnostic rates of forceps biopsy, brush biopsy, bronchial alveolar lavage and transbronchial needle aspiration were 81.6%, 49.4%, 18.2% and 62.6%, respectively, whereas that of biopsy combined with brush biopsy came up to 89.0%. Conclusion: Bronchoscopy is an important method in diagnosis of lung cancer. Different ages and genders of patients with lung cancer have different onset, and the distribution of pathological types is diverse. Attaching more importance to bronchoscopy and improving biopsy technique can significantly improve the diagnostic rate and provide reliable evidences for clinical treatment.

    U.S. military influenza surveillance uses electronic reporting of clinical diagnoses to monitor health of military personnel and detect naturally occurring and bioterrorism-related epidemics. While accurate, these systems lack in timeliness. More recently, researchers have used novel data sources to detect influenza in real time and capture nontraditional populations. With data-mining techniques, military social media users are identified and influenza-related discourse is integrated along with medical data into a comprehensive disease model. By leveraging heterogeneous data streams and developing dashboard biosurveillance analytics, the researchers hope to increase the speed at which outbreaks are detected and provide accurate disease forecasting among military personnel.

    As the number of recreational athletes performing exercise and participating in competitions at a high-level increases, exercise-induced cardiac symptoms may become a more common problem, not least because recreational athletes often continue high-level exercise programs into advanced ages. We investigated the prevalence of cardiac symptoms and diagnoses among 201 athletes referred for cardiac evaluation at a Sports Cardiology Clinic in Denmark. To our knowledge, this is the first systematic study of athletes referred for suspected cardiac disease. The athletes were all well-trained recreational to elite athletes who participated in various sports with different training loads and a wide age span (13-66 years). All patients were referred by physicians, primarily their general practitioner (38%), and palpitations were the most common cardiac symptom (40%). Cardiac symptoms had a sensitivity of 86% in detecting cardiac disease and a specificity of 13%. Cardiac disease was diagnosed in 44% of the patients, and atrial fibrillation was the most prevalent diagnosis (7.5%). Cardiac diseases with therapeutic- or sports-related consequences for the patients were diagnosed in 28% of the population, but only 1% received a recommendation to avoid high-level sports indefinitely. © 2015 John Wiley & Sons A/S.

    Full Text Available Clinicopathological studies are important in determining the brain lesions underlying dementia. Although almost 60% of individuals with dementia live in developing countries, few clinicopathological studies focus on these individuals. We investigated the frequency of neurodegenerative and vascular-related neuropathological lesions in 1,092 Brazilian admixed older adults, their correlation with cognitive and neuropsychiatric symptoms, and the accuracy of dementia subtype diagnosis.In this cross-sectional study, we describe clinical and neuropathological variables related to cognitive impairment in 1,092 participants (mean age = 74 y, 49% male, 69% white, and mean education = 4 y. Cognitive function was investigated using the Clinical Dementia Rating (CDR and the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE; neuropsychiatric symptoms were evaluated using the Neuropsychiatric Inventory (NPI. Associations between neuropathological lesions and cognitive impairment were investigated using ordinal logistic regression. We developed a neuropathological comorbidity (NPC score and compared it to CDR, IQCODE, and NPI scores. We also described and compared the frequency of neuropathological diagnosis to clinical diagnosis of dementia subtype. Forty-four percent of the sample met criteria for neuropathological diagnosis. Among these participants, 50% had neuropathological diagnoses of Alzheimer disease (AD, and 35% of vascular dementia (VaD. Neurofibrillary tangles (NFTs, hippocampal sclerosis, lacunar infarcts, hyaline atherosclerosis, siderocalcinosis, and Lewy body disease were independently associated with cognitive impairment. Higher NPC scores were associated with worse scores in the CDR sum of boxes (β = 1.33, 95% CI 1.20-1.46, IQCODE (β = 0.14, 95% CI 0.13-0.16, and NPI (β = 1.74, 95% CI = 1.33-2.16. Compared to neuropathological diagnoses, clinical diagnosis had high sensitivity to AD and high specificity to dementia with

    Next generation sequencing is transforming clinical medicine and genome research, providing a powerful route to establishing molecular diagnoses for genetic conditions; however, challenges remain given the volume and complexity of genetic variation. A number of methods integrate patient phenotype and genotypic data to prioritise variants as potentially causal. Some methods have a clinical focus while others are more research-oriented. With clinical applications in mind we compare results from alternative methods using 21 exomes for which the disease causal variant has been previously established through traditional clinical evaluation. In this case series we find that the PhenIX program is the most effective, ranking the true causal variant at between 1 and 10 in 85% of these cases. This is a significantly higher proportion than the combined results from five alternative methods tested (p = 0.003). The next best method is Exomiser (hiPHIVE), in which the causal variant is ranked 1-10 in 25% of cases. The widely different targets of these methods (more clinical focus, considering known Mendelian genes, in PhenIX, versus gene discovery in Exomiser) is perhaps not fully appreciated but may impact strongly on their utility for molecular diagnosis using clinical exome data.

    Full Text Available Abstract Background Shoulder dysfunction is common and pathology of the rotator cuff tendons and subacromial bursa are considered to be a major cause of pain and morbidity. Although many hypotheses exist there is no definitive understanding as to the origin of the pain arising from these structures. Research investigations from other tendons have placed intra-tendinous neovascularity as a potential mechanism of pain production. The prevalence of neovascularity in patients with a clinical diagnosis of rotator cuff tendinopathy is unknown. As such the primary aim of this pilot study was to investigate if neovascularity could be identified and to determine the prevalence of neovascularity in the rotator cuff tendons and subacromial bursa in subjects with unilateral shoulder pain clinically assessed to be rotator cuff tendinopathy. The secondary aims were to investigate the association between the presence of neovascularity and pain, duration of symptoms, and, neovascularity and shoulder function. Methods Patients with a clinical diagnosis of unilateral rotator cuff tendinopathy referred for a routine diagnostic ultrasound (US scan in a major London teaching hospital formed the study population. At referral patients were provided with an information document. On the day of the scan (on average, at least one week later the patients agreeing to participate were taken through the consent process and underwent an additional clinical examination prior to undergoing a bilateral grey scale and colour Doppler US examination (symptomatic and asymptomatic shoulder using a Philips HDI 5000 Sono CT US machine. The ultrasound scans were performed by one of two radiologists who recorded their findings and the final assessment was made by a third radiologist blinded both to the clinical examination and the ultrasound examination. The findings of the radiologists who performed the scans and the blinded radiologist were compared and any disagreements were resolved

    Wolf-Hirschhorn syndrome (WHS) is a multiple congenital anomaly-intellectual disability syndrome caused by a deletion involving chromosome 4p16.3. We report clinical and genetic findings of the first WHS patient diagnosed in central Africa. This boy who presented with cleft palate, microcephaly, severe growth delay, and intellectual disability was 12 years old. Typical craniofacial features were present, though the characteristic "Greek helmet" appearance of the nose was less evident, probably reflecting a variable expression related to the genetic background. The clinical diagnosis of WHS was confirmed by array CGH, which revealed a terminal 4p16.3 deletion of 3.47 Mb, typically associated with a milder phenotype, contributing to the long survival of this child in a developing country.

  6. Erythema elevatum diutinum as a first clinical manifestation for diagnosing HIV infection: case history

    Directory of Open Access Journals (Sweden)

    Patrícia Accioni Rover

    Full Text Available CONTEXT: Erythema elevatum diutinum is a chronic and rare dermatosis that is considered to be a variant of leukocytoclastic vasculitis. It is probably mediated by immune complexes. It is generally associated with autoimmune, neoplastic and infectious processes. Recently, it has been added to the group of specific dermatoses that are associated with HIV. CASE REPORT: We report on the case of a patient who had erythema elevatum diutinum as the first clinical evidence for diagnosing HIV infection. Dapsone was used in the treatment of this patient, and partial regression of the lesions was achieved within 15 days, even before antiretroviral therapy was prescribed. CONCLUSION: When there is a diagnosis of erythema elevatum diutinum, HIV infection should be investigated, especially in atypical and exacerbated clinical manifestations.

    Legionnaires' disease is a multisystem disease with life-threatening acute and severe form of pneumonia which is responsible for 2-9% pneumonia with high mortality. Eighty six respiratory tract samples and urine were collected from clinically diagnosed pneumonia patients and 12 water samples were collected from different environment. Identification of Legionella was done by culture and Polymerase Chain Reaction (PCR) of respiratory tract samples and environmental samples and Legionella Antigen (Ag) in urine was detected by Immunochromatographic test (ICT). Legionella was identified from 4 (4.65%) clinically diagnosed pneumonia patients of which 1(1.16%) case was culture positive, 1(1.16%) case was urine ICT positive and PCR was positive in all four cases. Of the 12 water samples tested, 4 (33.33%) samples were Legionella positive by PCR but culture results of these samples were negative. Identification of Legionella should be done by PCR in parallel with culture and urine ICT. Detection of Legionella in environmental samples is also needed to explore possible links between the water sources and disease transmission in population.

    2010-11-01

    Oedema is a frequent disorder and the easily detectable consequence of an increase of fluid located in the interstitial tissue. It could be localized or generalized and related either to a primary disturbance of hemodynamics at the capillary level, due to a modification of the Starling's law components with secondary water and saline retention, or to a primary retention of salt and water linked to a kidney abnormality. Generalized forms are pitting oedema, most often painless, white, bilateral and symmetric, distributed at the lower part of the body (localisation according to the gravitation law). They are different in their characteristics from localized oedema or lymphoedema which are tough. We propose a diagnostic approach based on medical history, clinical examination which allows a confident medical diagnosis and so an adapted therapy.

    Acute bronchiolitis comprises a major cause for morbidity in infants with viral infection which induces an immune inflammatory response that may produce long lasting harmful effects. Currently, there is no effective therapy for bronchiolitis. Our aim was to investigate the efficacy of five-day montelukast therapy in acute bronchiolitis management. The study included 50 infants with acute bronchiolitis. The infants with first episode of acute bronchiolitis were randomly assigned to receive daily montelukast dose of 4mg over five days after admission or no treatment. Plasma eotaxin, IL-4, IL-8 and IFN-gamma levels were evaluated before and after treatment by ELISA method. In the present study, the primary outcome measure was change in clinical severity score, whilst secondary outcome measures were changes in plasma eotaxin, IL-4, IL-8, IFN-gamma levels. No significant differences was found in clinical severity score with five-day montelukast treatment (p>0.05, Mann-Whitney U test). There were no significant differences in plasma eotaxin, IL-4, IL-8, IFN-gamma levels between the groups (p>0.05 Mann-Whitney U test). There was significant decrease in plasma IFN-gamma levels following five-day montelukast treatment (p=0.027, Wilcoxon). There were no significant differences in plasma IL-4, IL-8, IFN-gamma levels between the groups after five-day montelukast treatment (p>0.05, Wilcoxon). There was significant increase in eotaxin levels after five-day montelukast treatment (p=0.009, Wilcoxon). Our study showed that montelukast affected plasma IFN-gamma and eotaxin levels after five days of treatment. Further studies are needed to demonstrate effects of montelukast on chemokine levels in bronchiolitis. Copyright © 2014 SEICAP. Published by Elsevier Espana. All rights reserved.

    Few studies have focused the association between bullying and psychiatric disorders in clinical samples. The aim of this study was to examine if bullying behaviour was associated with psychiatric disorders and school well-being. The cross-sectional study was part of a health survey at St. Olav's University Hospital. The sample consisted of 685 adolescent patients aged 13-18 years who completed an electronic questionnaire. Clinical diagnoses were collected from clinical records. In this clinical psychiatric sample, 19% reported being bullied often or very often, and 51% reported being bullied from time to time. Logistic regression analyses showed associations between being a victim and having a mood disorder, and between being involved in bullying behaviour and reporting lower scores on school well-being. No difference was found in bullying behaviour on gender, age and SES. The risk of being a victim was high among adolescents in this clinical sample, especially among patients with mood disorders. Any involvement in bullying behaviour was associated with reduced school well-being.

    Most of the reports on instrumentalists' experiences of temporomandibular disorders (TMD) have been reported not by clinical examinations but by subjective questionnaires. The aim of this study was to investigate the clinical signs and subjective symptoms of TMD in a large number of instrumentalists objectively. A total of 739 musicians from a diverse range of instrument groups completed a TMD questionnaire. Among those who reported at least one symptom of TMD, 71 volunteers underwent clinical examinations and radiography for diag-nosis. Overall, 453 participants (61.3%) reported having one or more symptoms of TMD. The most frequently reported symptom was a clicking or popping sound, followed by temporomandibular joint (TMJ) pain, muscle pain, crepitus, and mouth opening limitations. Compared with lower-string instrumentalists, a clicking or popping sound was about 1.8 and 2 times more frequent in woodwind and brass instrumentalists, respectively. TMJ pain was about 3.2, 2.8, and 3.2 times more frequent in upper-string, woodwind, and brass instrumentalists, respectively. Muscle pain was about 1.5 times more frequent in instrumentalists with an elevated arm position than in those with a neutral arm position. The most frequent diagnosis was myalgia or myofascial pain (MFP), followed by disc displacement with reduction. Myalgia or MFP was 4.6 times more frequent in those practicing for no less than 3.5 hours daily than in those practicing for less than 3.5 hours. The results indicate that playing instruments can play a contributory role in the development of TMD.

    We sought to characterize the clinical determinants of mortality in patients with angiographically diagnosed ischemic or nonischemic cardiomyopathy. Patients with ischemic cardiomyopathy may have a worse prognosis than patients with nonischemic cardiomyopathy. Few studies have assessed the effect of ischemic versus nonischemic etiology on outcomes. We analyzed prospectively collected data on 3,787 patients with a left ventricular ejection fraction cardiomyopathy (n = 3,112) if they had a history of myocardial infarction, percutaneous transluminal coronary angioplasty, coronary artery bypass graft surgery or at least one major epicardial coronary artery with > or = 75% stenosis; all others were considered to have nonischemic cardiomyopathy (n = 675). The median age, ejection fraction and proportion of patients with New York Heart Association functional class III or IV symptoms for the nonischemic and ischemic groups were 55 years versus 63 years, 27% versus 32% and 57% versus 25%, respectively. After adjustment for baseline clinical risk factors and presenting characteristics, ischemic etiology remained an important independent predictor of 5-year mortality (p disease was a better predictor of survival than ischemic or nonischemic etiology (log likelihood chi-square 700 vs. 675, respectively). Ischemic etiology is a significant independent predictor of mortality in patients with cardiomyopathy. However, the extent of coronary artery disease contributes more prognostic information than the clinical diagnosis of ischemic or nonischemic cardiomyopathy. Further research is needed to refine the clinical definition of ischemic cardiomyopathy so that physicians can appropriately prescribe treatment and accurately predict outcome.

    Although several studies have compared patient outcomes by provider specialty in the treatment of back and joint pain, little is known about the cost-effectiveness of improving patient outcomes across specialties. This study uses a large-scale, nationally representative database to evaluate the cost-effectiveness of being treated by specific provider specialists for back and joint pain in the United States. The 2002-2012 Medical Expenditure Panel Surveys were used to examine patients diagnosed with back and/or joint problems seeking treatment from doctors (internal medicine, family/general, osteopathic medicine, orthopaedics, rheumatology, neurology) or other providers (chiropractor, physical therapist, acupuncturist, massage therapist). A total of 16,546 respondents aged 18 to 85 and clinically diagnosed with back/joint pain were examined. Self-reported measures of physical and mental health and general quality of life (measured by the EuroQol-5D) were compared with average total costs of treatment across medical providers. Total annual treatment costs per person ranged from $397 for family/general doctors to $1205 for rheumatologists. Cost-effectiveness analysis suggests that osteopathic, family/general, internal medicine doctors and chiropractors and massage therapists were more cost-effective than other specialties in improving physical function to back pain patients. For mental health measures, family/general and orthopaedic doctors and physical therapists were more cost-effective compared with other specialties. Similar to results on physical function, family/general, osteopathic and internal medicine doctors dominated other specialties. However, only massage therapy was cost-effective among non-doctor providers in improving quality of life measures. Patients seeking care for back and joint-related health problems face a wide range of treatments, costs and outcomes depending on which specialist provider they see. This study provides important insight on the

    After sudden cardiac death with negative autopsy, clinical screening of relatives identifies a high proportion of inherited arrhythmia syndrome. However, the efficacy of this screening in families not selected by autopsy has never been assessed. We aim to investigate the value of clinical screening in relatives of all subjects who died suddenly before 45 years of age. One hundred and three consecutive families who experienced unexplained sudden cardiac death before 45 years of age were included from May 2009 to December 2014 in a prospective multicenter registry. Clinical screening was provided to all relatives and performed in 64 families (230 relatives, 80 unexplained sudden cardiac death). Diagnosis was established in 16 families (25%), including Brugada syndrome (7), long QT syndromes (5), dilated cardiomyopathy (2), and hypertrophic cardiomyopathy (2). The diagnostic yield was mainly dependent on the number of screened relatives (3.8±3.4 screened relatives in diagnosed families versus 2.0±1.5; P<0.005) rising to 47% with at least 3 relatives. It additionally increased from 3 of 32 (9%) to 9 of 22 (41%) when both parents were screened (P=0.01). Diagnostic performance was also dependent on the exhaustiveness of screening (70% of complete screening in the diagnosed families versus 25%; P<0.0001) with 17 Brugada syndromes and 15 long QT syndromes diagnosed based on pharmacological tests. Even without autopsy, familial screening after sudden death in young patients is effective. Broad screening of relatives and systematic tests, including pharmacological challenges, greatly increases the likelihood of diagnosis in families. © 2017 American Heart Association, Inc.

    Full Text Available Abstract Background Patients with rheumatoid arthritis have a higher risk of low bone mineral density than normal age matched populations. There is limited evidence to support cost effectiveness of population screening in rheumatoid arthritis and case finding strategies have been proposed as a means to increase cost effectiveness of diagnostic screening for osteoporosis. This study aimed to assess the performance attributes of generic and rheumatoid arthritis specific clinical decision tools for diagnosing osteoporosis in a postmenopausal population with rheumatoid arthritis who attend ambulatory specialist rheumatology clinics. Methods A cross-sectional study of 127 ambulatory post-menopausal women with rheumatoid arthritis was performed. Patients currently receiving or who had previously received bone active therapy were excluded. Eligible women underwent clinical assessment and dual-energy-xray absorptiometry (DXA bone mineral density assessment. Clinical decision tools, including those specific for rheumatoid arthritis, were compared to seven generic post-menopausal tools to predict osteoporosis (defined as T score Results One hundred and twenty seven women participated. The median age was 62 (IQR 56–71 years. Median disease duration was 108 (60–168 months. Seventy two (57% women had no record of a previous DXA examination. Eighty (63% women had T scores at femoral neck or lumbar spine less than -1. The area under the ROC curve for clinical decision tool prediction of T score Conclusion There was limited utility of clinical decision tools for predicting osteoporosis in this patient population. Fracture prediction tools that include risk factors independent of BMD are needed.

    Chronic post-operative inguinal pain (CPIP) is the most significant complication following inguinal hernia repair. Patients without a palpable hernia prior to surgery seemed to report more CPIP. Our aim was to evaluate the effects of surgery on patients with a clinically inapparent inguinal hernia as diagnosed using ultrasonography. A total of 179 hernia repairs in patients with a positive ultrasonography but negative physical examination were analysed retrospectively. Patients with recurrent hernias, femoral hernias or previous surgery to the inguinal canal were excluded. The primary outcome was the presence of chronic postoperative inguinal pain (pain > 3 months postoperatively). Data on preoperative complaints, surgical technique and findings during ultrasonography and surgery were also studied in relation to the development of CPIP. A quarter (25.1%) of the patients reported chronic postoperative pain. Female gender (p = 0.03), high BMI (p = 0.04) and atypical symptoms prior to surgery (p inguinal hernia as diagnosed using ultrasonography report a high incidence of CPIP after elective hernia repair. Patients with atypical groin pain prior to surgery are especially prone to CPIP. It is questionable whether these hernias should be classified and treated as symptomatic inguinal hernias. The results advocate taking other causes of groin pain into consideration before choosing surgical treatment.

    A subset of facial melanoma in situ has histological features that overlap with those of "dysplastic" nevi. The authors evaluated this important diagnostic pitfall by assessing the frequency of melanoma as the final diagnosis in skin biopsies submitted over a 1-year period with a clinical impression of "atypical" or dysplastic nevus from the head or neck of adults. A total of 1998 biopsies met inclusion criteria. Final diagnoses included both melanocytic and nonmelanocytic processes. Clear trends were noted based on the age of the patient with benign nevi encompassing nearly 70% of specimens in patients aged 21-29 years and nevus. However, the authors' findings suggest that atypical nevi with histological features of dysplastic nevi occur on the head and neck of adults, including elderly adults. The incidence of such lesions decreases with age as the incidence of melanoma increases, and careful clinicopathologic correlation is vital.

    To evaluate the effect of dementing illnesses on the risk of dying, taking into account other conditions that would shorten survival. Five-year follow-up of community survey of dementia. Five-year data were obtained for the 3531 subjects, aged 65 years and older, who participated in the 1987 population survey of dementia in Shanghai, China. Time to death. Relative risks of dying were calculated for demographic variables, dementia diagnoses based on findings of clinical evaluations, and 15 reported prevalent medical conditions using the proportional hazards model. In those subjects aged 65 to 74 years, the mortality risk ratio was 5.4 (95% confidence interval, 2.0 to 14.6) for Alzheimer's disease and 7.2 (95% confidence interval, 3.6 to 14.4) for vascular dementia. The risk ratio for Alzheimer's disease was similar to the mortality risk ratio for cancer (5.6 [range, 2.9 to 10.9]). In this age group, dementing illnesses were uncommon, and few deaths were therefore attributable to the dementing illnesses. In those subjects aged 75 years and older, the mortality risk ratios were 2.8 (95% confidence interval, 2.1 to 3.6) for Alzheimer's disease, 3.5 (95% confidence interval, 2.4 to 5.1) for vascular dementia, and 3.6 (95% confidence interval, 2.0 to 6.7) for "other dementias." Because these dementing disorders were common in those subjects aged 75 years and older, 23.7% of the risk of death could be attributed to these disorders. Both Alzheimer's disease and vascular dementias are truly malignant and constitute major risk factors for death in persons older than 75 years.

  20. Avoiding pitfalls in diagnosing basilar artery occlusive disease: clinical and imaging clues - case report

    Full Text Available CONTEXT: The aim of this paper was to report on the characteristics that aid in establishing the diagnosis of basilar artery occlusive disease (BAOD among patients with hemiparesis and few or minor symptoms of vertebrobasilar disease. CASE REPORT: This report describes two cases in a public university hospital in São Paulo, Brazil. We present clinical and imaging findings from two patients with hemiparesis and severe BAOD, but without clinically relevant carotid artery disease (CAD. One patient presented transient ischemic attacks consisting of spells of right hemiparesis that became progressively more frequent, up to twice a week. The neurological examination revealed slight right hemiparesis and right homonymous hemianopsia. Magnetic resonance imaging (MRI revealed pontine and occipital infarcts. Magnetic resonance angiography and digital subtraction angiography revealed severe basilar artery stenosis. The other patient presented sudden left-side hemiparesis and hypoesthesia. One year earlier, she had reported sudden onset of vertigo that, at that time, was attributed to peripheral vestibulopathy and was not further investigated. MRI showed a right-side pontine infarct and an old infarct in the right cerebellar hemisphere. Basilar artery occlusion was diagnosed. Both patients presented their symptoms while receiving aspirin, and became asymptomatic after treatment with warfarin. CONCLUSIONS: Misdiagnosing asymptomatic CAD as the cause of symptoms in BAOD can have disastrous consequences, such as unnecessary carotid endarterectomy and exposure to this surgical risk while failing to offer the best available treatment for BAOD. Clinical and imaging features provided important clues for diagnosis in the cases presented.

    We prospectively compared clinical examination (CE) with plain films (PXR) and both tools with CT in patients sustaining blunt trauma. There were 1388 patients who had both PXR and CT of whom 168 (12.1%) were diagnosed with a fracture by CT. CE findings most predictive of fracture included age (OR, 1.025; CI, 1.011-1.039), hip pain (OR, 4.971; CI, 2.508-9.854), internal rotation of the leg (OR, 4.880; CI, 1.980-12.027), or tenderness to palpation over the sacrum (OR, 2.297; CI, 1.144-4.612), over the right or left hip (OR, 3.626; CI, 1.823-7.214), or diffusely throughout the pelvis (OR, 16.445; CI, 4.277-63.237). These factors were still predictive of pelvic fractures even in patients with a Glasgow Coma Scale score less than 13. There were 136 fractures identified by PXR all of which were identified by CE (sensitivity 100% [136 of 136], negative predictive value 100% [619 of 619]). There were six patients with negative clinical examinations and positive CTs (sensitivity 96.4% [162 of 168], negative predictive value 99.03% [613 of 619]), none of which were hemodynamically significant. The sensitivity for PXR compared with CT was 79.17 per cent (133 of 168) and the NPV was 97.2 per cent (1217 of 1252). CE is a reliable way to diagnose pelvic fractures and PXR is a poor screening tool for these injuries compared with CT. Because the majority of patients undergo CT after blunt trauma, routine screening radiographs should be eliminated.

    The historical diagnosis of Prader-Willi syndrome (PWS), a complex genetic disorder, in adults by clinical presentation rather than genetic testing has limited genetic subtype-specific psychometric investigations and treatment. Genetic testing and clinical psychiatric evaluation using DSM-IV-TR criteria were undertaken on 72 adult residents (34M; 38F) from the Prader-Willi Homes of Oconomowoc (PWHO), a specialty PWS group home system. Methylation specific-multiplex ligation probe amplification and high-resolution microarrays were analyzed for methylation status, 15q11-q13 deletions and maternal uniparental disomy 15 (mUPD15). Seventy (33M; 37F) of 72 residents were genetically confirmed and 36 (51%) had Type I or Type II deletions; 29 (42%) with mUPD15 and 5 (7%) with imprinting defects from three separate families. Psychiatric comorbidities were classified as anxiety disorder (38%), excoriation (skin picking) (33%), intermittent explosive disorder [(30%-predominantly among males at 45% compared with females at 16% (OR=4.3, 95%CI 1.4-13.1, p < 0.008)] and psychotic features (23%). Psychiatric diagnoses did not differ between mUPD15 vs deletion, but a greater number of psychiatric diagnoses were observed for larger Type I (4.3) vs smaller Type II (3.6) deletions when age was controlled (F = 5.0, p < 0.04). Adults with PWS presented with uniformly higher rates of psychiatric comorbidities which differed by genetic subtype with gender-specific trends. This article is protected by copyright.

    Shoulder impingement syndrome is a clinically common entity involving trapping of tendons or bursa with typical clinical findings. Important radiological procedures are ultrasound, magnetic resonance imaging (MRI) and MR arthrography. Projection radiography and computed tomography (CT) are ideal to identify bony changes and CT arthrography also serves as an alternative method in cases of contraindications for MRI. These modalities support the clinically suspected diagnosis of impingement syndrome and may identify its cause in primary diagnosis. In addition, effects of impingement are determined by imaging. Therapy decisions are based on a synopsis of radiological and clinical findings. The sensitivity and specificity of these imaging modalities with regard to the diagnostics of a clinically evident impingement syndrome are given in this review article. Orthopedic and trauma surgeons express the suspicion of an impingement syndrome based on patient history and physical examination and radiologists confirm structural changes and damage of intra-articular structures using dedicated imaging techniques.

    This paper aimed to provide an overview from published randomised clinical trials of the efficacy and tolerability of lamotrigine monotherapy compared with carbamazepine and phenytoin when initiated in adult patients with newly diagnosed epilepsy. The review included two double-blind, randomised trials of lamotrigine monotherapy compared with carbamazepine and phenytoin, respectively, and one open randomised trial comparing lamotrigine with carbamazepine. The results of the three trials were pooled for comparison of tolerability. Multicentre in Europe. Adult patients (>12 years of age) with newly diagnosed partial seizures (with or without secondary generalisation) and primary generalised tonic-clonic seizures (n = 443 patients on lamotrigine, n = 246 on carbamazepine, n = 95 on phenytoin). Comparable efficacy was demonstrated between lamotrigine and both carbamazepine or phenytoin. The time to withdrawal survival analysis supported a significant difference in favour of lamotrigine [hazard ratio 1.57 (95% CI 1.07 to 2.31)] in the double-blind trial. Overall, twice the proportion of patients withdrew from carbamazepine or phenytoin because of adverse events (19.1 and 18.9%, respectively) compared with lamotrigine (9.5%). Lamotrigine was particularly well tolerated with regard to adverse effects affecting the central nervous system. Rash was the most common adverse event necessitating discontinuation of each drug, the rates being very similar across treatment groups (6.1% on lamotrigine, 8.9% on carbamazepine, 5.3% on phenytoin). The rate of rash resulting in withdrawal of lamotrigine was clearly related to the dose escalation employed in the different trials during the first month of therapy. Lamotrigine is an effective monotherapy treatment for adult patients with newly diagnosed epilepsy, and is better tolerated than either carbamazepine or phenytoin monotherapy. The incidence of rash requiring withdrawal of lamotrigine is related to dose escalation (2.2% of

    Full Text Available Abstract Background Only half of all depressions are diagnosed in Primary Health Care (PHC. Depression can remain undetected for a long time and entail high costs for care and low quality of life for the individuals. Drop in clinic is a common form of organizing health care; however the visits are short and focus on solving the most urgent problems. The aim of this study was to investigate the prevalence and severity of depression among women visiting the GPs' drop in clinic and to identify possible clues for depression among women. Methods The two-stage screening method with "high risk feedback" was used. Beck's Depression Inventory (BDI was used to screen 155 women visiting two GPs' drop in clinic. Women who screened positive (BDI score ≥10 were invited by the GP to a repeat visit. Major depression (MDD was diagnosed according to DSM-IV criteria and the severity was assessed with Montgomery-Asberg Depression Rating Scale (MADRS. Women with BDI score Results The two-stage method worked well with a low rate of withdrawals in the second step, when the GP invited the women to a repeat visit. The prevalence of depression was 22.4% (95% CI 15.6–29.2. The severity was mild in 43%, moderate in 53% and severe in 3%. The depressed women mentioned mental symptoms significantly more often (69% than the controls (15% and were to a higher extent sick-listed for a longer period than 14 days. Nearly one third of the depressed women did not mention mental symptoms. The majority of the women who screened as false positive for depression had crisis reactions and needed further care from health professionals in PHC. Referrals to a psychiatrist were few and revealed often psychiatric co-morbidity. Conclusion The prevalence of previously undiagnosed depression among women visiting GPs' drop in clinic was high. Clues for depression were identified in the depressed women's symptom presentation; they often mention mental symptoms when they visit the GP for somatic

    The British Psychological Society proposes that clinical psychologists are well placed to move beyond psychiatric diagnoses and develop alternative practices. This study sought to explore what the application of these guiding principles looks like in clinical practice, the challenges faced and possible routes forward. A purpose-designed survey was completed by 305 respondents and a thematic analysis completed. Thematic analysis was used to identify five superordinate themes relating to individuals, relational, others, structures and society, comprising of a total of 21 group themes. The presented group themes highlight an array of approaches to practicing beyond diagnosis and factors that help and hinder such action; from scaffolding change, becoming leaders, relating to the multi-disciplinary team, restructuring services and the processes of change. A key concept was "playing the diagnostic game". "Playing the diagnostic game" enables psychologists to manage an array of tensions and anxieties: conflicts between belief and practice, relationships with colleagues, and dilemmas of position and power. It also potentially limits a concerted questioning of diagnosis and consideration of alternatives. An alternative conceptual framework for non-diagnostic practice is needed to aid the collective efforts of clinical psychologists developing their practice beyond diagnosis, some of which have been highlighted in this study. Until then, ways of mitigating the perceived threats to questioning diagnosis need further exploration, theorising and backing.

    In the Netherlands, dementia syndromes are diagnosed in specialized memory outpatient clinics (MC). Many radiologists are not trained to assess magnetic resonance imaging (MRI) scans with respect to possible radiological changes that may indicate neurodegenerative disease. This is a cross-sectional descriptive study. A survey was sent to all Dutch MC and included questions as to how MRI scans are assessed by radiologists and how these assessments are used in the diagnostic process. In most MC, radiologists report on typical Alzheimer pathology and large vessel disease. Small vessel disease and other anatomical changes signifying neurodegenerative disease frequently are not assessed. In the majority of MC, the radiological assessment is not standardized, and physicians assess MRI for themselves to use this information to discuss the consensus diagnosis subsequently. MRI assessment by radiologists in Dutch MC probably underestimates the presence of cerebrovascular and neurodegenerative disease. The validity of standardized assessment protocols in routine clinical practice deserves further study, as the implementation of standardization outside research settings could improve diagnostic accuracy.

    American Indians are at greater risk for Rocky Mountain spotted fever (RMSF) than the general U.S. population. The epidemiology of RMSF among American Indians was examined by using Indian Health Service inpatient and outpatient records with an RMSF International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis. For 2001-2008, 958 American Indian patients with clinical diagnoses of RMSF were reported. The average annual RMSF incidence was 94.6 per 1,000,000 persons, with a significant increasing incidence trend from 24.2 in 2001 to 139.4 in 2008 (P = 0.006). Most (89%) RMSF hospital visits occurred in the Southern Plains and Southwest regions, where the average annual incidence rates were 277.2 and 49.4, respectively. Only the Southwest region had a significant increasing incidence trend (P = 0.005), likely linked to the emergence of brown dog ticks as an RMSF vector in eastern Arizona. It is important to continue monitoring RMSF infection to inform public health interventions that target RMSF reduction in high-risk populations.

    The clinical course of type 1 diabetes mellitus (T1DM) has changed in recent decades. The aim of our study was to assess the long-term (> 20 years) clinical status of a patient cohort with T1DM under a specific treatment and follow-up program. A single center, observational, cross-sectional study was conducted of a patient cohort diagnosed with T1DM in the 1986-1994 period at our tertiary university hospital. Clinical characteristics, metabolic parameters, and occurrence of chronic complications and comorbidities after > 20 years of follow-up were collected. All subjects entered our specific program for patients with newly-diagnosed T1D and were followed up using the same clinical protocol. Data are shown as mean (standard deviation) or as number of patients and percentage. The appropriate test was used to compare quantitative and qualitative data. A P value <0.05 was considered statistically significant. A total of 279 patients were recorded, of whom 153 (53.6% women; mean age 46.6±8.6 years; age at onset 23.3±8.8 years; disease duration, 23.3±2.6 years) continued to attend our diabetes unit at the time of the analysis. Of these patients, 24.8% were administered continuous subcutaneous insulin infusion (CSII). Mean HbA1c in the past 5 years and in the last year were7.8±0.9% and 7.7±1.1% respectively (7.3±1.5% in those given CSII). Smoking was reported by 19.6% of patients, while 15.7% had high blood pressure and 37.9% dyslipidemia. Diabetic retinopathy was diagnosed in 20.4%, and 11.3% of the total cohort had nephropathy. Only 1.3% of our patients had a history of CVD. Data collected from a cohort of patients with T1DM for more than 2 decades regularly followed up with a specific program in a tertiary university hospital suggest a remarkably low prevalence of diabetic complications.

    Equine sarcoids (ES) are common, difficult to treat, and have high recurrence rates. Viscum album extracts (VAE) are used in human cancer treatment. That therapy with VAE (Iscador P) is effective in the treatment of ES. Fifty-three horses (444 ES); 42 were treated with VAE or placebo as monotherapy; 11 were treated with VAE or placebo after selective excision of ES. Prospective, randomised, blinded, clinical trial. Horses were randomly assigned to treatment (VAE; n=32) or control group (Placebo; n=21). One milliliter of VAE (Iscador P) in increasing concentrations from 0.1 to 20 mg/mL or physiological NaCl solution was given SC 3 times a week over 105 days. Number, localization, and type of the ES were documented over 12 months. A subset of 163 clinically diagnosed equine sarcoid (CDES) lesions (95 VAE, 68 Placebo) was evaluated in detail, considering clinical findings and tumor volume. No undesired adverse effects were observed except for mild edema at the injection site in 5 of 32 horses (16%). Complete or partial regression was observed in 13 horses of the VAE group (41%) and in 3 of the control horses (14%; P<.05). After VAE treatment, 48 of 95 CDES (67%) showed an improvement compared with 17 of 68 CDES in the control group (40%; P<.01). Twenty-seven CDES had disappeared completely in the VAE group (38%) compared with 9 CDES in the control group (13% NS). VAE (Iscador P) represents a safe and effective treatment for CDES.

    Tertiary trauma survey is widely implemented in trauma care to identify all injuries in trauma patients. However, various studies consistently show that some trauma patients have missed injuries. In this study, we developed a clinical decision model to identify patients who are at risk for delayed diagnosed injuries. During a period of 18 months, we collected the medical records of all the adult patients who presented after a high-energy trauma at the emergency department of a Dutch trauma centre. The type of trauma, patient characteristics, the radiology studies performed, Glasgow Coma Scale, Revised Trauma Score, and Injury Severity Score (ISS) were registered. We thoroughly screened all medical records for delayed diagnosed injuries. Stepwise logistic regression analysis was used to identify the variables associated with the outcome delayed diagnosed injuries and to develop a clinical prediction model. We included 475 patients. Thirteen (2.7%) patients with delayed diagnosed injuries were identified. Stepwise logistic regression analysis revealed several models with the ISS, ICU admittance, and CT-head as predictive variables. The model we proposed with the ISS could identify patients who are at a risk for delayed diagnosed injuries with a sensitivity of 92.3% and a specificity of 86.4%. Our newly developed clinical decision model can identify patients who are at a risk for delayed diagnosed injuries and who should undergo an intensified search for potential unidentified injuries.

    Zinc-α2-glycoprotein (ZAG) has been proposed to play a role in the pathogenesis of insulin resistance. Previous studies in humans and in rodents have produced conflicting results regarding the link between ZAG and insulin resistance. The objective of this study was to examine the relationships between ZAG and insulin resistance in cross-sectional and interventional studies. Serum ZAG (determined with ELISA) was compared with various parameters related to insulin resistance in subjects with normal glucose tolerance, impaired glucose tolerance (IGT), and newly diagnosed type 2 diabetes mellitus (T2DM), and in women with or without polycystic ovary syndrome (PCOS). Euglycemic-hyperinsulinemic clamps were performed in healthy and PCOS women. Real-time RT-PCR and Western blotting were used to assess mRNA and protein expression of ZAG. The effect of a glucagon-like peptide-1 agonist on ZAG was studied in a 12-week liraglutide treatment trial. Circulating ZAG was lower in patients with IGT and newly diagnosed T2DM than in controls. Circulating ZAG correlated positively with HDL cholesterol and adiponectin, and correlated inversely with BMI, waist-to-hip ratio, body fat percentage, triglycerides, fasting blood glucose, fasting insulin, HbA1c, and homeostasis model assessment of insulin resistance (HOMA-IR). On multivariate analysis, ZAG was independently associated with BMI, HOMA-IR, and adiponectin. ZAG mRNA and protein were decreased in adipose tissue of T2DM patients. Moreover, circulating ZAG levels were lower in women with PCOS than in women with high insulin sensitivity. Liraglutide treatment for 12 weeks significantly increased circulating ZAG levels. We conclude that ZAG may be an adipokine associated with insulin resistance.

    Penicillin skin testing is rarely used to undiagnose penicillin "allergy" in the United States, partially because of concern that commercially available materials are inadequate. We determined whether skin testing with only commercially available penicilloyl-poly-lysine and penicillin followed by an oral amoxicillin challenge, if skin test-negative, can safely identify clinically significant penicillin allergy. Five hundred sequential persons with positive history of penicillin "allergy" were evaluated by skin testing with penicilloyl-poly-lysine and penicillin between June 8, 2010, and March 29, 2012. All persons with negative skin tests were given an oral amoxicillin challenge and observed for 1 hour. Persons undergoing penicillin allergy testing were representative of all health plan members with penicillin allergy. Only 4 persons (0.8%; 95% CI, 0.32%-2.03%) had a positive skin test result. Only 4 persons (0.8%; 95% CI, 0.32%-2.03%) had an acute objective oral amoxicillin challenge reaction. Fifteen persons (3.0%; 95% CI, 1.83%-4.98%) had subjective oral challenge reactions, either acute transient itching or dizziness. All were women and 11 (73.3%) had multiple drug intolerance syndrome. None had severe reactions or objective signs. These were not considered to be positive challenge reactions. Sixty-eight subjects (13.6%) who were negative on testing were exposed to 88 courses of penicillins during 90 days of follow-up. New reactions were reported after 4 courses (4.5%), 3 (75%) occurring in subjects with multiple drug intolerance syndrome. Penicillin skin testing, using only penicilloyl-poly-lysine and penicillin, followed by oral amoxicillin challenge, if negative, can safely identify clinically significant IgE-mediated penicillin allergy in patients who use health care in the United States at this time.

    Full Text Available In this paper, I claim that subjectivity is a way of being that is constituted through a set of practices in which the self is subject to the dangers of fictionalizing and plotting her life and self-image. I examine some ways of becoming subject through narratives and through theatrical performance before others. Through these practices, a real and active subjectivity is revealed, capable of self-knowledge and self-transformation.

    .2%-100.0%), and the rate of known spine metastasis recurrence despite treatment for all skin malignancies was 2.8% (n = 17/608, range 0.0%-33.3%). Age greater than 65 years, sacral spinal involvement, presence of a neurological deficit, and nonambulatory status were associated with decreased survival in patients diagnosed with a primary skin cancer spinal metastasis. All other clinical or prognostic parameters were of low or insufficient strength. CONCLUSIONS Patients diagnosed with a primary skin cancer metastasis to the spine have poor overall survival with the exception of those with BCC. The median duration of survival for patients who received surgical intervention alone, medical management (chemotherapy and/or radiation) alone, or the combination of therapies was similar across interventions. Age, spinal region, and neurological status may be associated with poor survival following surgery.

    Full Text Available Objective To investigate the MRI abnormalities and acute madopar responsiveness test in diagnosing progressive supranuclear palsy (PSP and Parkinson's disease (PD. Methods Seventeen patients with PSP and 17 gender and age matched patients with PD were studied with cranial MRI examinations and results of acute madopar responsiveness test, and the clinical manifestations of PSP were summarized. Results The atrophy of the midbrain tegmentum and hummingbird sign was demonstrated in all of the PSP patients in our study, but was not observed in the PD patients. The areas of the midbrain on mid-sagittal MRI in PSP patients [(77.35 ± 15.30 mm2] were significantly smaller than that in those with PD [(142.35 ± 31.49 mm2]. The average ratio of the area of the midbrain to the area of pons in the patients with PSP [(14.31 ± 2.47%] was significantly smaller than that in those with PD [(24.08 ± 4.73%; P = 0.000, for all]. According to the result of acute madopar responsiveness test, the maximum Unified Parkinson's Disease Rating Scale (UPDRS Ⅲ improvement rate of 2 patients with PSP and 16 patients with PD was more than 30% (χ2 = 23.142, P = 0.000. Conclusion The assessment of the mid-sagittal MRI and acute madopar responsiveness test may be a useful method to differentiate PSP from PD.

    Estimate the incidence and the epidemiological and clinical characteristics of patients diagnosed with tuberculosis in a county hospital located in the north western area of the Autonomous Region of Madrid, to determine if there has been an increase due to immigration. Tuberculosis cases from January, 1996 to June, 2001 were analysed, researched through the Microbiology and Pathologic Anatomy Laboratory, fetching information such as demographics, clinical studies and disease diagnostics from the different medical histories. A total of 66 tuberculosis cases were registered, ten of them among immigrants, with an incidence of 13/100,000 inhabitants in 1996, decreasing to a 7/100,000 incidence in 2000. The age average is 34 with double the incidence in males (31/100,000) than females (17/100,000). The main risk factor is alcoholism with 11 cases (16.7%). The most commonly used diagnostic tests were the thorax radiography (61/66, 92%) with 57 (93.4%) positive identifications, culture of esputo (47/66, 71%) with 32 (68%) positive ids, and the Mantoux test (28, 42%) with 20 (71.4%) positive ids. The location of the illness is mainly pleuro-pulmonar in 50 cases (75%). There were almost no atypical mycobacterium found (5 cases). Overall, response to treatment with 3 drugs (isoniacide, rifampicine, piracinamide) was good in 88% of patients, with the average treatment lasting 6.8 months (ED: 2.8). The incidence of tuberculosis in the north western area of Autonomous Community of Madrid is below that of the rest of our Community. It dipped in 1997 and has been stable around 9/100,000 inhabitants until 2000, even with the effect of immigration.

    We report the case of a dyspneic patient with a five-liter pleural empyema that was diagnosed and managed in a resource-limited clinic in a rural part of Sierra Leone. The diagnosis and management of this condition are usually guided by imaging modalities such as X-rays or CT scans. However, these resources may not be available in austere settings in developing countries. Because emergency physicians work in a variety of clinical settings, they should be well versed in the use of portable ultrasound machines to diagnose, treat, and manage many different conditions.

    Full Text Available Aim: Catatonia is caused by a variety of psychiatric and organic conditions. The onset, clinical profile, and response to treatment may vary depending on the underlying cause. The study is an attempt to explore clinical profile, possible etiological correlates with neurotic/psychotic spectrum illnesses, and response to treatment and outcome in patients of catatonia. Materials and Methods: Retrospective chart analysis by using semistructured data sheet for the analysis of sociodemographic data, clinical profile, precipitating event, and response to treatment in patients with catatonic symptoms admitted to IHBAS (Institute of Human Behaviour and Allied Sciences, New Delhi, India from January 2009 to December 2010 was undertaken. Results: Catatonia was commonly observed in patients with the following profile - late twenties, female, Hindu religion, urban background, and housewives. Psychotic spectrum disorder (57%, N=35 was the most commonly entertained diagnosis and affective disorder (18%, N=11 being the second common. Thirty four percent of the subjects responded to lorazepam treatment and rest required modified electroconvulsive therapy (MECT. Conclusion: Catatonia is more likely to be associated with Schizophrenia and Other Psychotic Disorders in Indian settings. Majority of patients responded to therapy either by lorazepam alone or to its augmentation with modified ECT. The study being a retrospective one, the sample being representative of the treatment seeking group only, and unavailability of the follow up data were the limitations of the study

    BACKGROUND: Centralization of specialized health care in Denmark has caused increased geographical distance to health-care providers, which may be a barrier for Alzheimer patients to seek health care. We examined the incidence of Alzheimer diagnosis in Denmark between 2000 and 2009 and investigated...... the association between patients' distance to Alzheimer clinics and Alzheimer diagnoses. METHODS: Data of all individuals aged 65+ years were collected from Danish national registers. Incidences of Alzheimer diagnoses were analysed with joinpoint regression and hazard ratios (HRs) for Alzheimer diagnoses were...... analysed with Cox regressions. RESULTS: The annual incidence of Alzheimer diagnoses increased with 32.5% [95% confidence interval (CI): 7.1-63.8] among individuals aged 65-74 years from 2000 to 2002 and with 29.1% (95% CI: 11.0-50.2) among individuals aged 75+ years from 2000 to 2003.

    Science.gov (United States)

    2012-01-01

    Background Development of new tinnitus treatments requires prospective placebo-controlled randomized trials to prove their efficacy. The Tinnitus Questionnaire (TQ) is a validated and commonly used instrument for assessment of tinnitus severity and has been used in many clinical studies. Defining the Minimal Clinically Important Difference (MCID) for TQ changes is an important step to a better interpretation of the clinical relevance of changes observed in clinical trials. In this study we aimed to estimate the minimum change of the TQ score that could be considered clinically relevant. Methods 757 patients with chronic tinnitus were pooled from the TRI database and the RESET study. An anchor-based approach using the Clinical Global Impression (CGI) scale and distributional approaches were used to estimate MCID. Receiver Operating Characteristic (ROC) curves were calculated to define optimal TQ change cutoffs discriminating between minimally changed and unchanged subjects. Results The relationship between TQ change scores and CGI ratings of change was good (r = 0.52, p MCID for improvement was −5 points and for deterioration +1 points. Conclusion Distribution and anchor-based methods yielded comparable results in identifying MCIDs. ΔTQ scores of −5 and +1 points were identified as the minimal clinically relevant change for improvement and worsening respectively. The asymmetry of the MCIDs for improvement and worsening may be related to expectation effects. PMID:22781703

    Fatty liver is one of the most commonly found disease by abdominal ultrasonography. The status of fatty liver is classified into mild, moderate and severe degrees. The study was conducted to investigate the clinical significance of fatty liver using ultrasonography. Test set consisted of 2,185 patients who visited D healthcare center in Daejeon to receive an abdominal ultrasonic test from January to December 2007. Out of the 2185 patients, 524 patients was diagnosed as fatty liver (290 male and 234 female patients). They were divided into three groups, group I for mild degree. II for moderate degree, and III for severe degree, depending on the echo of liver parenchyma, the sound attenuation, and the visibility of intrahepatic blood vessels and diaphragm. Then the correlation of obesity indices, liver function tests and metabolic syndrome was analyzed for males and females separately. As for the degree of fatty liver, 350 cases (66.8%) were classified as group I, 153 cases (29.2%) as group II, and 21 cases (4.1%) as group III. In addition, severe degree of fatty liver was more frequently found in males than in females. The mean ages of three groups for males were 46.1, 44.5, and 39.1, and those for females were 48.8, 50.2, 52.4, respectively. Males with lower mean ages have severely of fatty liver for both males and females. The results in this study show that the classification into three degrees of fatty liver in ultrasonography practice is helpful to treat and observe the progress of fatty liver. In addition, careful examination is required to measure the severity of fatty liver as well as detection of it. A standardized method to classify the degree of fatty liver is also needed for more objective measurement.

    In HIV-infected patients with intrathoracic lymphadenopathy, it is not known whether clinical and radiographic findings are useful in predicting a specific diagnosis. We determined the etiology and predictors of the etiology of computed tomography (CT)-diagnosed intrathoracic lymphadenopathy in HIV-infected patients evaluated from June 1993 through April 1999. Multivariate analyses were performed to determine clinical and radiographic predictors of the three most common diagnoses. Of 318 patients, 110 (35%) had lymphadenopathy on chest CT. Among these 110 patients, tuberculosis/nontuberculous mycobacterial disease ( = 31), bacterial pneumonia ( = 26), and lymphoma ( = 21) were the most common diagnoses. Multivariate analysis identified cough and necrosis of lymph nodes on chest CT as independent predictors of tuberculosis/nontuberculous mycobacterial disease. African-American race, symptoms for 1 to 7 days, dyspnea, and presence of airways disease on chest CT were independent predictors of bacterial pneumonia; symptoms for >7 days, absence of cough, and absence of pulmonary nodules on CT independently predicted lymphoma. Intrathoracic lymphadenopathy is a frequent chest CT finding in HIV-infected patients. Opportunistic infections and lymphoma are the most common causes, and specific clinical and radiographic features can suggest these particular diagnoses.

    Objectives Malignant melanoma has high morbidity and mortality rates. Early diagnosis improves prognosis. Clinical prediction rules (CPRs) can be used to stratify patients with symptoms of suspected malignant melanoma to improve early diagnosis. We conducted a systematic review of CPRs for melanoma diagnosis in ambulatory care. Design Systematic review. Data sources A comprehensive search of PubMed, EMBASE, PROSPERO, CINAHL, the Cochrane Library and SCOPUS was conducted in May 2015, using combinations of keywords and medical subject headings (MeSH) terms. Study selection and data extraction Studies deriving and validating, validating or assessing the impact of a CPR for predicting melanoma diagnosis in ambulatory care were included. Data extraction and methodological quality assessment were guided by the CHARMS checklist. Results From 16 334 studies reviewed, 51 were included, validating the performance of 24 unique CPRs. Three impact analysis studies were identified. Five studies were set in primary care. The most commonly evaluated CPRs were the ABCD, more than one or uneven distribution of Colour, or a large (greater than 6 mm) Diameter (ABCD) dermoscopy rule (at a cut-point of >4.75; 8 studies; pooled sensitivity 0.85, 95% CI 0.73 to 0.93, specificity 0.72, 95% CI 0.65 to 0.78) and the 7-point dermoscopy checklist (at a cut-point of ≥1 recommending ruling in melanoma; 11 studies; pooled sensitivity 0.77, 95% CI 0.61 to 0.88, specificity 0.80, 95% CI 0.59 to 0.92). The methodological quality of studies varied. Conclusions At their recommended cut-points, the ABCD dermoscopy rule is more useful for ruling out melanoma than the 7-point dermoscopy checklist. A focus on impact analysis will help translate melanoma risk prediction rules into useful tools for clinical practice. PMID:28264830

    Full Text Available By evaluating abnormal metabolism, magnetic resonance spectroscopy (MRS is a highly effective tool for diagnosing prostate cancer (PC. Our study has indicated that the level of citrate (Ci and the ratio of the content of choline (Cho and creatine (Cr to that of citrate ((Cho + Cr/Ci are the most sensitive and specific indicators. These may be effectively used separately (to diagnose tumor involvement and to determine the degree of tumor differentiation and as a part of the authors’ discriminant model.The findings suggest that it is expedient to use MRS in the comprehensive diagnosis of PC.

    Three-dimensional (3D) image rendering capability of a commercially available 3D-optical coherence tomogram (OCT) system was used to diagnose a subclinical but symptomatic case of hypotony maculopathy in an eye with significant cataract and an only-eyed patient. Bleb revision improved intraocular pressure and symptoms, confirmed by repeat OCT imaging. Hypotony maculopathy may be subclinical and difficult to diagnose particularly in eyes with non-clear ocular media. Use of spectral domain OCT can be complementary to improve patient outcomes.

    To determine the relationship between clinically diagnosed catheter-associated urinary tract infection (CAUTI) and standardized criteria and to assess microorganism-level differences in symptom burden in a cohort of catheterized nursing home (NH) residents. Post hoc analysis of a prospective longitudinal study. Twelve NHs in southeast Michigan. NH residents with indwelling urinary catheters (n = 233; 90% white, 52% male, mean age 73.7). Clinical and demographic data, including CAUTI epidemiology and symptoms, were obtained at study enrollment, 14 days, and monthly thereafter for up to 1 year. One hundred twenty participants with an indwelling catheter (51%) were prescribed systemic antibiotics for 182 clinically diagnosed CAUTIs. Common signs and symptoms were acute change in mental status (28%), fever (21%), and leukocytosis (13%). Forty percent of clinically diagnosed CAUTIs met Loeb's minimum criteria, 32% met National Health Safety Network (NHSN) criteria, and 50% met Loeb's minimum or NHSN criteria. CAUTIs involving Staphylococcus aureus and Enterococcus spp. were least likely to meet criteria. CAUTIs involving Klebsiella pneumoniae were most likely to meet Loeb's minimum criteria (odds ratio (OR) = 9.7, 95% confidence interval (CI) = 2.3-40.3), possibly because of an association with acute change in mental status (OR = 5.9, 95% CI = 1.8-19.4). Fifty percent of clinically diagnosed CAUTIs met standardized criteria, which represents an improvement in antibiotic prescribing practices. At the microorganism level, exploratory data indicate that symptom burden may differ between microorganisms. Exploration of CAUTI signs and symptoms associated with specific microorganisms may yield beneficial information to refine existing tools to guide appropriate antibiotic treatment. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    2017-03-01

    When confronted with various findings on thoracic radiographs, fourth-year veterinary students often have difficulty generating appropriate lists of differential diagnoses. The purpose of this one-group, pretest, posttest experimental study was to determine if a game could be used as an adjunct teaching method to improve students' understanding of connections between imaging findings and differential diagnoses. A novel board game focusing on differential diagnoses in thoracic radiography was developed. One hundred fourth-year veterinary students took a brief pretest, played the board game, and took a brief posttest as a part of their respective clinical radiology rotations. Pretest results were compared to posttest results using a paired t-test to determine if playing the game impacted student understanding. Students' mean scores on the posttest were significantly higher than mean pretest scores (P board game resulted in improved short-term understanding of thoracic differential diagnoses by fourth-year students, and use of the board game on a clinical rotation seems to be a beneficial part of the learning process. © 2016 American College of Veterinary Radiology.

    Evidence suggests prolonged exposure to lower levels of low-density lipoprotein cholesterol (LDL-C), starting at a younger age, substantially lowers cardiovascular (CV) risk. Accordingly, the CV pandemic affecting younger population in low- to low-middle-income countries, where statin usage is poor even in secondary prevention, may benefit from lipid-lowering nutritional products, as nutritional intervention is generally preferred in these cultures. However, the safety and efficacy of such preparations have not been systematically tested. In this multicenter, double-blind study, 191 statin-free subjects with newly-diagnosed hyperlipidemia (LDL-C >120 mg/dL, 3.11 mmol/L) and no evidence of CV disease were randomized to one capsule of a proprietary bioactive phytonutrient formulation containing red yeast rice, grape-seed, niacinamide, and folic acid (RYR-NS) or matched placebo twice daily, along with lifestyle modification, for 12 wk. Mean baseline LDL-C levels were 148.5 ± 24.0 mg/dL (3.85 ± 0.62 mmol/L) and 148.6 ± 21.9 mg/dL (3.85 ± 0.57 mmol/L) in the RYR-NS and placebo groups respectively. Compared with placebo, RYR-NS resulted in a significant reduction in LDL-C (-29.4% versus -3.5%, P < 0.0001) and non-high-density lipoprotein cholesterol (non-HDL-C; -29.8% versus -10.3%, P < 0.0001) at 12 wk. With RYR-NS, 43.4% individuals attained desirable LDL-C levels and 55.4% desirable non-HDL-C levels by week 12, compared to only 0% and 1.1%, respectively, at baseline. No safety issues were observed. This study demonstrates the efficacy and safety of RYR-NS in lowering LDL-C and non-HDL-C after 12 wk, with magnitude of LDL-C reduction being comparable to that seen with moderate-intensity statin therapy. Further long-term studies are required to determine the impact of RYR-NS on treatment adherence and clinical outcomes. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

    The results of a survey of the medical consumption of 4,500 patients at the Belarussian-Dutch Outpatient Clinic in Gomel during 1991-1993 are presented and discussed. Analysis of the patient registration data was focused on complaints related to possible enhanced radiation exposure of the patients since the reactor incident at Chernobyl in 1986. The pattern of complaints and diagnoses was comparable to the situation in a Dutch outpatient clinic, except for a higher number of goitre, gastritis, gastric and duodenal ulcers. Diagnoses that could be attributed to increased radiation exposure were not enhanced compared to the pattern in a Dutch population of similar size, except for a higher number of thyroid disease. 19 refs.

    Physicians often diagnose diverticulitis and prescribe antibiotics in outpatients with abdominal pain and tenderness without other evidence. We investigated the misattribution of irritable bowel syndrome (IBS) symptoms to diverticulitis in outpatients. In patients diagnosed with diverticulitis and dispensed antibiotics in an integrated healthcare system, we retrospectively compared 15,846 outpatients managed without computed tomography (CT) versus 3750 emergency department/inpatients who had CT. We assessed demographics and past history, including 17 symptom-based somatic and 11 mental disorders and three somatic-mental comorbidity pairs (dyads) coded over 3 years and seven drug classes dispensed over 1 year before diagnosis. Univariate analysis showed small intergroup demographic differences. Outpatients had increases in prior diverticulitis, including outpatient-managed episodes, total somatic diagnoses (p diverticulitis history, IBS, chest pain, dyspepsia, fibromyalgia, low back pain, migraine, acute reaction to stress, and antispasmodic and anxiolytic dispensing and negatively associated with non-dependent drug abuse and opioid dispensing (p ≤ .0226). Multiple types of indirect and concordant evidence suggest misattribution of IBS pain to diverticulitis and unnecessary antibiotic therapy in outpatients.

    Full Text Available AIM: To determine the role of subjective assessment using McMonnies dry eye questionnaire in diagnosing dry eye disease and its association with clinical tests. METHODS: There were 500 patients screened for dry eye using McMonnies dry eye questionnaire between May to October 2013 at the outpatient Department of Ophthalmology of a medical college hospital. All 500 patients were subjected to clinical tests. Dry eye was defined as having one or more symptoms often or all the time. Positive signs were if one or both eyes revealed tear film breakup time (TBUT of ≤10s, a Schirmer test score of ≤10 mm, a Rose Bengal staining score of ≥1, a Lissamine green staining score of ≥1 or existence of meibomian gland disease (≥grade 1. Statistical analysis was performed to describe the distribution of symptoms and signs, to assess the correlations between McMonnies score (MS and variable clinical signs of dry eye, and to explore the association between dry eye symptoms and variable clinical signs. Analysis was performed using software package Epi info. A Probability (P value using Chi-square test of RESULTS: Dry eye prevalence with symptoms (questionnaire, Schirmer test, TBUT, Rose Bengal staining and Lissamine green staining was 25.6%, 15.20%, 20.80%, 23.60%, and 22.60% respectively. Among those with severe symptoms (MS>20, 75.86% had a low TBUT (CONCLUSION: Subjective assessment plays an important role in diagnosing dry eye disease. There is strong correlation between MS and Schirmer test, TBUT, Rose Bengal staining and Lissamine green staining in normal as well as marginal and pathological dry eye.

    The purpose of this study was to evaluate the clinical outcome of boron neutron capture therapy (BNCT) and conventional treatment in patients with newly diagnosed glioblastoma. Since 1998 we treated 23 newly-diagosed GBM patients with BNCT without any additional chemotherapy. Their median survival time was 19.5 months; the 2-, 3-, and 5-year survival rates were 31.8%, 22.7%, and 9.1%, respectively. The clinical results of BNCT in patients with GBM are similar to those of recent conventional treatments based on radiotherapy with concomitant and adjuvant temozolomide.

    To determine whether hypertonic saline nasal spray relieves nasal symptoms and shortens illness duration in patients with the common cold or acute rhinosinusitis. Randomized trial with 2 control groups. Two family practice clinics. One hundred forty-three adult patients with a cold or sinus infection. Patients with allergic rhinitis, symptoms for more than 3 weeks, or other respiratory diagnoses were excluded, as were those who had used topical decongestants. Hypertonic saline or normal saline spray 3 times a day or observation. Subjects completed a 7-day symptom checklist that included a well-being question ("Do you feel back to normal?"). Nasal symptom score (sum of scores for nasal congestion, rhinorrhea, and headache) on day 3 and day of well-being (day of symptom resolution). Data were collected for 119 subjects. No difference was found in either primary outcome when hypertonic saline was compared with either normal saline or observation. Mean day of well-being was 8.3 (95% confidence interval [CI], 6.9-9.7), 9.2 (95% CI, 6.9-11.43), and 8.0 (95% CI, 6.7-9.3) days in the hypertonic saline, normal saline, and observation groups, respectively. Day 3 mean nasal symptom score was 3.8 (95% CI, 3.0-4.5) for hypertonic saline, 3.7 (95% CI, 2.9-4.5) for normal saline, and 4.1 (95% CI, 3.5-4.7) for observation. Only 44% of the patients would use the hypertonic saline spray again. Thirty-two percent noted burning, compared with 13% of the normal saline group (P = .05). Hypertonic saline does not improve nasal symptoms or illness duration in patients with the common cold or rhinosinusitis.

    The prevalence of electronic medical record (EMR) systems has made mass-screening for clinical trials viable through secondary uses of clinical data, which often exist in both structured and free text formats. The tradeoffs of using information in either data format for clinical trials screening are understudied. This paper compares the results of clinical trial eligibility queries over ICD9-encoded diagnoses and NLP-processed textual discharge summaries. The strengths and weaknesses of both data sources are summarized along the following dimensions: information completeness, expressiveness, code granularity, and accuracy of temporal information. We conclude that NLP-processed patient reports supplement important information for eligibility screening and should be used in combination with structured data.

    Full Text Available Abstract Background The features of carotid atherosclerosis in ketosis-onset diabetes have not been investigated. Our aim was to evaluate the prevalence and clinical characteristics of carotid atherosclerosis in newly diagnosed Chinese diabetic patients with ketosis but without islet-associated autoantibodies. Methods In total, 423 newly diagnosed Chinese patients with diabetes including 208 ketosis-onset diabetics without islet-associated autoantibodies, 215 non-ketotic type 2 diabetics and 79 control subjects without diabetes were studied. Carotid atherosclerosis was defined as the presence of atherosclerotic plaques in any of the carotid vessel segments. Carotid intima-media thickness (CIMT, carotid atherosclerotic plaque formation and stenosis were assessed and compared among the three groups based on Doppler ultrasound examination. The clinical features of carotid atherosclerotic lesions were analysed, and the risk factors associated with carotid atherosclerosis were evaluated using binary logistic regression in patients with diabetes. Results The prevalence of carotid atherosclerosis was significantly higher in the ketosis-onset diabetic group (30.80% than in the control group (15.2%, p=0.020 after adjusting for age- and sex-related differences, but no significant difference was observed in comparison to the non-ketotic diabetic group (35.8%, p=0.487. The mean CIMT of the ketosis-onset diabetics (0.70±0.20 mm was markedly higher than that of the control subjects (0.57±0.08 mm, p Conclusions The prevalence and risk of carotid atherosclerosis were significantly higher in the ketosis-onset diabetics than in the control subjects but similar to that in the non-ketotic type 2 diabetics. The characteristics of carotid atherosclerotic lesions in the ketosis-onset diabetics resembled those in the non-ketotic type 2 diabetics. Our findings support the classification of ketosis-onset diabetes as a subtype of type 2 diabetes.

    The aims of this study were to determine the characteristics of self-mutilation (SM) and examine the relationship between SM and psychopathy in male subjects with antisocial personality disorder (APD). APD diagnosis was established by the Structured Clinical Interview for DSM-III-R Axis II Disorders. Subjects (N = 116) were assessed using the Psychopathy Checklist-Revised and a semi-structured self-mutilation questionnaire form. In males with APD, the percentages of psychopathy and SM were 48.3% (N =56) and 96.6% (N = 112), respectively. There were positive correlations between severity of psychopathy and severity, number, and frequency of SM. Considerably high rates of SM and psychopathy were found in Turkish males with APD. The features of SM were associated with comorbidity of psychopathy. These results showed the importance of exploring the self-injurious behavior and psychopathy when diagnosed with APD.

    This study examines the stability of ICD-10 diagnoses of patients admitted to Al Ain (United Arab Emirates) inpatients psychiatric unit during the period from November 1993 to August 1995. Diagnostic stability is a measure of the degree to which diagnoses remained unchanged at a later hospital admission. One hundred and seven patients were admitted more than once during this period, accounting for 168 readmissions. High levels of diagnostic stability were found for ICD-10 Fl-psychiatric disorders (100%), F2-schizophrenia (87%), F3-bipolar disorders (87%) and F3-depressive disorders (73%). A poor level of stability was found for patients with neurotic, stress related and adjustment disorders (F4), ranging from zero for somatoform disorders to 50% for generalized anxiety and panic disorders. Poor levels of stability were also found for other psychoses (excluding schizophrenia and affective psychoses) and personality disorders. We conclude that the introduction of ICD-10 as a formal diagnostic system has greatly improved the temporal stability of the most commonly encountered psychiatric disorders (ICD-10 Fl to F3 disorders), confirming the construct validity of those psychiatric disorders. Further investigations are required to evaluate the diagnostic stability of neurotic and other psychotic disorders.

    Full Text Available BackgroundLatent autoimmune diabetes in adults (LADA refers to a specific type of diabetes characterized by adult onset, presence of islet auto-antibodies, insulin independence at the time of diagnosis, and rapid decline in β-cell function. The prevalence of LADA among patients with type 2 diabetes varies from 2% to 20% according to the study population. Since most studies on the prevalence of LADA performed in Korea were conducted in patients who had been tested for anti-glutamic acid decarboxylase antibody (GADAb, a selection bias could not be excluded. In this study, we examined the prevalence and clinical characteristics of LADA among adult patients recently diagnosed with type 2 diabetes.MethodsWe included 462 patients who were diagnosed with type 2 diabetes within 5 years from the time this study was performed. We measured GADAb, fasting insulin level, fasting C-peptide level, fasting plasma glucose level, HbA1c, and serum lipid profiles and collected data on clinical characteristics.ResultsThe prevalence of LADA was 4.3% (20/462 among adult patients with newly diagnosed type 2 diabetes. Compared with the GADAb-negative patients, the GADAb-positive patients had lower fasting C-peptide levels (1.2±0.8 ng/mL vs. 2.0±1.2 ng/mL, P=0.004. Other metabolic features were not significantly different between the two groups.ConclusionThe prevalence of LADA is 4.3% among Korean adult patients with recently diagnosed type 2 diabetes. The Korean LADA patients exhibited decreased insulin secretory capacity as reflected by lower C-peptide levels.

    To examine the prevalence rates of bullying involvement and their correlates in adolescents diagnosed with ADHD in Taiwan. Bullying involvement, family and ADHD characteristics, the levels of behavioral inhibition system (BIS) and behavioral approach system (BAS), and psychiatric comorbidity were assessed in 287 adolescents with ADHD. The multiple regression analysis was used to examine the correlate of bullying victimization and perpetration. The prevalence rates of the pure victims, pure perpetrators, and victim-perpetrators were 14.6%, 8.4%, and 5.6%, respectively. Young age, a high BIS score, autism spectrum disorders, and low satisfaction with family relationships were associated with severe bullying victimization. A high score of fun seeking on the BAS and low satisfaction with family relationships were associated with severe bullying perpetration. A high proportion of adolescents with ADHD are involved in bullying. Multiple factors are associated with bullying involvement in adolescents with ADHD.

    The purpose of this analysis was to assess the potential of BNCT, with L-boronophenylalanine (L-BPA), as first line radiotherapy for glioblastoma multiforme (GBM). The survival of patients with newly diagnosed GBM from a phase II BNCT study was compared with those from the two arms of a phase III study with conventional radiotherapy (RT) vs. RT plus concomitant and adjuvant medication with temozolomide (TMZ). A small subgroup, for which the methylation status of the O{sup 6}-methylguanine-DNA methyltransferase (MGMT) DNA-repair gene was known, was also considered. The results indicated that the use of BNCT with BPA should be explored in a stratified randomized phase II trial in which patients with the unmethylated MGMT DNA-repair gene are offered BNCT vs. RT plus TMZ.

    2010-01-01

    Background Migraine is a common disorder that is highly co-morbid with psychopathological conditions such as depression and anxiety. Despite the extensive research and availability of treatment, migraine remains under-recognised and undertreated. The aim of this study was to design a short and practical screening tool to identify migraine for clinical and research purposes. Methods The structured migraine interview (SMI) based on the International Classification of Headache Disorders (ICHD) criteria was used in a clinical setting of headache sufferers and compared to clinical diagnosis by headache specialist. In addition to the validating characteristics of the interview different methods of administration were also tested. Results The SMI has high sensitivity (0.87) and modest specificity (0.58) when compared to headache specialist's clinical diagnosis. Conclusions Our study demonstrated that a structured interview based on the ICHD criteria is a useful and valid tool to identify migraine in research settings and to a limited extent in clinical settings, and could be used in studies on large samples where clinical interviews are less practical.

    Delusional infestation, which encompasses both delusions of parasitosis and delusions of infestation with inanimate objects (sometimes called Morgellons disease), has been said to represent a distinct and encapsulated delusion, that is, a stand-alone diagnosis. Anecdotally, we have observed that patients with delusional infestation often have one or more psychiatric comorbid conditions and that delusional infestation should not be regarded as a stand-alone diagnosis. The purpose of this study was to identify whether patients with delusional infestation have psychiatric comorbid conditions. We therefore identified patients who had been formally evaluated in the Department of Psychiatry during their visit to Mayo Clinic. We retrospectively searched for and reviewed the cases of all patients with delusional infestation seen from 2001 through 2007 at Mayo Clinic, Rochester, Minnesota, and who underwent psychiatric evaluation. The diagnoses resulting from psychiatric evaluation were analyzed. During the 7-year study period, 109 patients seen for delusional infestation at Mayo Clinic were referred to the Department of Psychiatry, 54 (50%) of whom actually followed through with psychiatric consultation. Of these 54 patients, 40 (74%) received additional active psychiatric diagnoses; 14 patients (26%) had delusional infestation alone. Abnormal personality traits were rarely documented. Most patients with delusional infestation have multiple coexisting or underlying psychiatric disorders. Therefore, evaluation by a psychiatrist, when possible, is advised for all patients with delusional infestation. Copyright © 2012 The Academy of Psychosomatic Medicine. Published by Elsevier Inc.

    To investigate the clinical features and perinatal treatment of thrombocytopenia induced by different causes during pregnancy.Clinical data from 195 pregnant women with thrombocytopenia attending 2 tertiary hospitals from January 2014 to October 2016 were retrospectively studied. The obtained data were analyzed with SPSS 19.0 software.There were 117 (60.0%), 55 (28.2%), and 23 cases (11.8%) of pregnancy-associated thrombocytopenia (PAT), idiopathic thrombocytopenia (ITP), and hypertensive disorder in pregnancy (PIH), respectively. The percentage of nulliparous women, gestational age at delivery, date of diagnosis of thrombocytopenia, and delivery mode significantly differed between the patients in these 3 groups (P thrombocytopenia in pregnancy are diverse, and the clinical features vary widely. Timely analysis is needed to determine the primary cause of thrombocytopenia, and appropriate therapy should then be selected to effectively improve the prognosis of pregnancies.

    The prognosis of combined cases of pulmonary fibrosis and emphysema is unresolved partially because radiological differentiation between usual interstitial pneumonia and nonspecific interstitial pneumonia is difficult in coexisting emphysema cases. The purpose of this study was to clarify the clinical impact of emphysema on the survival of patients with idiopathic pulmonary fibrosis (IPF). One hundred and seven patients with interstitial lung diseases were diagnosed by surgical lung biopsies between 2006 and 2012, and 47 patients were diagnosed with IPF through multidisciplinary discussion. Emphysema on high-resolution computed tomography scans was evaluated semiquantitatively by visual scoring. Eight out of the 47 IPF patients showed a higher emphysema score (>3) and were diagnosed to have IPF-emphysema. The median survival time of patients with IPF-emphysema (1,734 days) from the initial diagnosis was significantly shorter than that of patients with IPF alone (2,229 days) by Kaplan-Meier analysis (p = 0.007, log-rank test). Univariate Cox proportional hazard regression analyses revealed that a higher total emphysema score (>3.0) was a significantly poor prognostic factor in addition to Krebs von den Lungen-6, surfactant protein-D, arterial oxygen tension, percent forced vital capacity, and percent diffusing capacity of carbon monoxide (%DLCO). Multivariate Cox proportional hazard regression analyses with the stepwise method showed that higher total emphysema score (>3) and %DLCO were significantly poor prognostic factors. The prognosis of IPF-emphysema was significantly worse than that of IPF alone. © 2016 S. Karger AG, Basel.

    Full Text Available Abstract Background Our Thyroid-Multidisciplinary Clinic is a large referral site for thyroid diseases. Thyroid biopsies are mainly performed for thyroid cancer screening. Yet, Hashimoto thyroiditis (HT is being too frequently diagnosed. The prevalence of HT is reported as 0.3-1.2% or twice the prevalence of type 1 diabetes. However, the prevalence of HT confirmed by cytology is still uncertain. To evaluate different aspects of thyroid physiopathology including prevalence of Hashimoto's, a database of clinical features, ultrasound images and cytology results of patients referred for FNA of thyroid nodules was prospectively developed. Methods We retrospectively studied 811 consecutive patients for whom ultrasound guided thyroid FNA biopsies were performed at our clinic over 2.5 year period (Mar/2006-Sep/2008. Results The analysis of our database revealed that from 761 patients, 102 (13.4% had HT, from whom 56 (7.4% were euthyroid or had sub-clinical (non-hypothyroid disease, and 46 (6% were clinically hypothyroid. Conclusions This is the first study to show such a high prevalence of HT diagnosed by ultrasound-guided FNA. More strikingly, the prevalence of euthyroid HT, appears to be >5% similar to that of type 2 diabetes. Based on our results, there might be a need to follow up on cytological Hashimoto's to monitor for thyroid failure, especially in high risk states, like pregnancy. The potential risk for thyroid cancer in patients with biopsy-proven inflammation of thyroid epithelium remains to be established prospectively. However, it may explain the increased risk for thyroid cancer observed in patients with elevated but within normal TSH.

    Mastitis is positioned as the most vital ailment in dairy cows in light of conventional cost examinations. The aim of the present study was to evaluate the diagnostic value of different acute phase proteins (APPs), pro-inflammatory cytokines, and oxidative stress biomarkers in healthy cows and in those with clinical or subclinical mastitis and to localize APP gene expression in the milk of mastitic cows. Therefore, 20 subclinical mastitic cows with positive California Mastitis Test (CMT) results and no clinical signs of mastitis, 15 clinically mastitic cows, and 15 healthy cows with negative CMT results and somatic cell count (SCC) of mastitis, except for total protein, albumin, and GSH levels and the TAC, which were significantly (p mastitis, while Fb expression was absent. The present study demonstrates that APPs, pro-inflammatory cytokines, and indicators of oxidative stress may serve as biomarkers of clinical and subclinical mastitis. Interestingly, the expression of SAA and Hp indicates the local de novo synthesis of these APPs within the mammary glands. Furthermore, the presence of SAA and Hp transcripts in milk cells derived from pathogen-free mammary glands proved their constitutive expression. However, future studies with more extensive baseline sampling are still needed to establish and validate the reference values for APPs, cytokines, and oxidative stress markers in cows.

    Canine visceral leishmaniasis (CVL) diagnosis is still a challenge in endemic areas with limited diagnostic resources. This study proposes a score with the potential to distinguish positive CVL cases from negative ones. We studied 265 dogs that tested positive for CVL on ELISA and parasitological tests. A score ranging between 0 and 19 was recorded on the basis of clinical signs. Dogs with CVL had an overall higher positivity of the majority of clinical signs than did dogs without CVL or with ehrlichiosis. Clinical signs such as enlarged lymph nodes (83.93%), muzzle/ear lesions (55.36%), nutritional status (51.79%), bristle condition (57.14%), pale mucosal colour (48.21%), onychogryphosis (58.93%), skin lesion (39.28%), bleeding (12.50%), muzzle depigmentation (41.07%), alopecia (39.29%), blepharitis (21.43%), and keratoconjunctivitis (42.86%) were more frequent in dogs with CVL than in dogs with ehrlichiosis or without CVL. Moreover, the clinical score increased according to the positivity of all diagnostic tests (ELISA, p sign-based score for CVL diagnosis suggested herein can help veterinarians reliably identify dogs with CVL in endemic areas with limited diagnostic resources.

    Full Text Available Abstract Background Treatment of chronic diseases such as chronic obstructive pulmonary disease (COPD is complicated by the presence of comorbidities. The objective of this analysis was to estimate the prevalence of comorbidity in COPD using nationally-representative data. Methods This study draws from a multi-year analytic sample of 14,828 subjects aged 45+, including 995 with COPD, from the National Health and Nutrition Examination Survey (NHANES, 1999–2008. COPD was defined by self-reported physician diagnosis of chronic bronchitis or emphysema; patients who reported a diagnosis of asthma were excluded. Using population weights, we estimated the age-and-gender-stratified prevalence of 22 comorbid conditions that may influence COPD and its treatment. Results Subjects 45+ with physician-diagnosed COPD were more likely than subjects without physician-diagnosed COPD to have coexisting arthritis (54.6% vs. 36.9%, depression (20.6% vs. 12.5%, osteoporosis (16.9% vs. 8.5%, cancer (16.5% vs. 9.9%, coronary heart disease (12.7% vs. 6.1%, congestive heart failure (12.1% vs. 3.9%, and stroke (8.9% vs. 4.6%. Subjects with COPD were also more likely to report mobility difficulty (55.6% vs. 32.5%, use of >4 prescription medications (51.8% vs. 32.1, dizziness/balance problems (41.1% vs. 23.8%, urinary incontinence (34.9% vs. 27.3%, memory problems (18.5% vs. 8.8%, low glomerular filtration rate (16.2% vs. 10.5%, and visual impairment (14.0% vs. 9.6%. All reported comparisons have p  Conclusions Our study indicates that COPD management may need to take into account a complex spectrum of comorbidities. This work identifies which conditions are most common in a nationally-representative set of COPD patients (physician-diagnosed, a necessary step for setting research priorities and developing clinical practice guidelines that address COPD within the context of comorbidity.

    Fluoxetine (FLX) has been one of the most widely studied selective serotonin reuptake inhibitors in adolescents. Despite its efficacy, however, 30% to 40% of patients do not respond to treatment. The aim of this study was to evaluate whether clinical improvement or adverse events are related to the corrected dose of FLX at 8 and 12 weeks after starting treatment in a sample of adolescents diagnosed with major depressive disorder, obsessive-compulsive disorder, or generalized anxiety disorder. Seventy-four subjects aged between 10 and 17 years participated in the study. Clinical improvement was measured with the Clinical Global Impression-Improvement Scale, whereas the UKU (Udvalg for Klinske Undersogelser) scale was administered to assess adverse effects of treatment. Fluoxetine per kilograms of body weight was related to serum concentration of FLX, NORFLX (norfluoxetine), FLX + NORFLX, and FLX/NORFLX. No relationship was found between dose-corrected FLX levels and therapeutic or adverse effects. No differences in serum concentrations were found between responders and nonresponders to treatment. Sex differences were observed in relation to dose and FLX serum concentration. The analysis by diagnosis revealed differences in FLX dose between obsessive-compulsive disorder patients and both generalized anxiety disorder and major depressive disorder patients. Fluoxetine response seems to be influenced by factors such as sex, diagnosis, or certain genes that might be involved in the drug's pharmacokinetics and pharmacodynamics. Clinical and pharmacogenetic studies are needed to elucidate further the differences between treatment responders and nonresponders.

    Full Text Available Purpose : To verify the efficacy and safety of lamotrigine (LTG monotherapy in newly diagnosed children with epilepsy. Methods : We prospectively enrolled 148 children who had undergone LTG monotherapy at our institution between September 2002 and June 2009. Twenty-nine patients were excluded: 19 due to incomplete data and 10 were lost to follow up. The data of the remaining 119 patients was analyzed. Results : We enrolled 119 pediatric epilepsy patients (aged 2.8-19.3 years; 66 males and 53 females in this study. Out of 119 patients, 29 (25.2% had generalized epilepsy and 90 (74.8% had partial epilepsy. The responses of seizure reduction were as follows: Seizure freedom (no seizure attack for at least 6 months in 87/111 (78.4%, n=111 patients; partial response (reduced seizure frequency compared to baseline in 13 (11.7% patients; and persistent seizure in 11 (9.9% patients. The seizure freedom rate was in 81.6% in patients with partial seizure (75.9% for complex partial seizure and 90.9% for benign rolandic epilepsy and 44.8% in patients with generalized epilepsy (30.0% for absence seizure, 35.7% for juvenile myoclonic epilepsy patients, and 100.0% for idiopathic generalized epilepsy patients. Adverse reactions were reported in 17 (14.3% patients, and 8 patients (6.7% discontinued LTG because of rash and tic. No patient experienced severe adverse reaction such as Stevens-Johnson syndrome. Conclusion : LTG showed excellent therapeutic response and had few significant adverse effects. Our findings report may contribute in promoting the use of LTG monotherapy in epileptic children.

  13. Strategies to exclude subjects who conceal and fabricate information when enrolling in clinical trials

    Full Text Available Clinical trials within the US face an increasing challenge with the recruitment of quality candidates. One readily available group of subjects that have high rates of participation in clinical research are subjects who enroll in multiple trials for the purpose of generating income through study payments. Aside from issues of safety and generalizability, evidence suggests that these subjects employ methods of deception to qualify for the strict entrance criteria of some studies, including concealing information and fabricating information. Including these subjects in research poses a significant risk to the integrity of data quality and study designs. Strategies to limit enrollment of subjects whose motivation is generating income have not been systematically addressed in the literature. The present paper is intended to provide investigators with a range of strategies for developing and implementing a study protocol with protections to minimize the enrollment of subjects whose primary motivation for enrolling is to generate income. This multifaceted approach includes recommendations for advertising strategies, payment strategies, telephone screening strategies, and baseline screening strategies. The approach also includes recommendations for attending to inconsistent study data and subject motivation. Implementing these strategies may be more or less important depending upon the vulnerability of the study design to subject deception. Although these strategies may help researchers exclude subjects with a higher rate of deceptive practices, widespread adoption of subject registries would go a long way to decrease the chances of subjects enrolling in multiple studies or more than once in the same study.

    The present investigation was performed in a population of patients with temporomandibular disorders (TMD), and it was designed to assess the correlation between self-reported questionnaire-based bruxism diagnosis and a diagnosis based on history taking plus clinical examination. One-hundred-fifty-nine patients with TMD underwent an assessment including a questionnaire investigating five bruxism-related items (i.e. sleep grinding, sleep grinding referral by bed partner, sleep clenching, awake clenching, awake grinding) and an interview (i.e. oral history taking with specific focus on bruxism habits) plus a clinical examination to evaluate bruxism signs and symptoms. The correlation between findings of the questionnaire, viz., patients' report, and findings of the interview/oral history taking plus clinical examination, viz., clinicians' diagnosis, was assessed by means of φ coefficient. The highest correlations were achieved for the sleep grinding referral item (φ = 0·932) and for the awake clenching item (φ = 0·811), whilst lower correlation values were found for the other items (φ values ranging from 0·363 to 0·641). The percentage of disagreement between the two diagnostic approaches ranged between 1·8% and 18·2%. Within the limits of the present investigation, it can be suggested that a strong positive correlation between a self-reported and a clinically based approach to bruxism diagnosis can be achieved as for awake clenching, whilst lower levels of correlation were detected for sleep-time activities. © 2013 John Wiley & Sons Ltd.

    Studies of previous cohorts have demonstrated an association between a status of overweight/obesity and the presence of knee and hand osteoarthritis (OA). However, no data on the effect of these factors on the OA burden are available. The aim of the present study was to analyze the effect of being overweight or obese on the incidence of routinely diagnosed knee, hip, and hand OA. The study was conducted in a population-based cohort using primary care records from the Sistema d'Informació per al Desenvolupament de l'Investigació en Atenció Primària database (>5.5 million subjects, covering >80% of the population of Catalonia, Spain). Participants were subjects ages ≥40 years who were without a diagnosis of OA on January 1, 2006 and had available body mass index (BMI) data. All subjects were followed up from January 1, 2006 to December 31, 2010 or to the time of loss to follow-up or death. Measures included the World Health Organization categories of BMI (exposure), and incident clinical diagnoses of knee, hip, or hand OA according to International Classification of Diseases, Tenth Revision codes. In total, 1,764,061 subjects were observed for a median follow-up period of 4.45 years (interquartile range 4.19-4.98 years). Incidence rates (per 1,000 person-years at risk) of knee, hip, and hand OA were 3.7 (99% confidence interval [99% CI] 3.6-3.8), 1.7 (99% CI 1.7-1.8), and 2.6 (99% CI 2.5-2.7), respectively, among subjects in the normal weight category, and 19.5 (99% CI 19.1-19.9), 3.8 (99% CI 3.7-4.0), and 4.0 (99% CI 3.9-4.2), respectively, in those with a classification of grade II obesity. Compared to subjects with normal weight, being overweight or obese increased the risk of OA at all 3 joint sites, especially at the knee. A status of overweight, grade I obesity, and grade II obesity increased the risk of knee OA by a factor of 2-fold, 3.1-fold, and 4.7-fold, respectively. Being overweight or obese increases the risk of hand, hip, and knee OA, with the

    To summarise clinical presentation, diagnostic findings and long-term outcome for dogs clinically diagnosed with meningoencephalomyelitis of unknown origin affecting the spinal cord alone. Medical records were reviewed for dogs diagnosed with presumptive spinal-only meningoencephalomyelitis of unknown origin between 2006 and 2015. 21 dogs were included; the majority presented with an acute (43%) or chronic (52%) onset of neurological signs. Ambulatory paresis was the most common neurological presentation (67%). Neurological examination most commonly revealed a T3-L3 myelopathy, and spinal hyperaesthesia was a common finding (71%). A spinal cord lesion was visible in 90% of cases on magnetic resonance imaging. Eighteen lesions (86%) showed parenchymal contrast enhancement and 17 lesions (81%) showed contrast enhancement of overlying meninges. All dogs were treated with immunosuppressive doses of glucocorticosteroids, sometimes combined with cytosine arabinoside. At time of data capture, 10/21 dogs (48%) had died or been euthanased because of the condition. Overall median survival time was 669 days. Meningoencephalomyelitis of unknown origin should be considered in the differential diagnosis of dogs presenting with a progressive myelopathy. Magnetic resonance imaging features can possibly help to distinguish presumptive meningoencephalomyelitis of unknown origin from other more common spinal diseases. Overall, long-term survival is guarded, approximately 50% of dogs will die or be euthanased despite appropriate therapy. © 2017 British Small Animal Veterinary Association.

    Periapical cysts (PC) and periapical granulomas (PG) are the two most common chronic inflammatory periapical diseases, but their clinicoradiological characteristics can vary depending on the methods employed in each study. The aim of the present work was to analyze the clinical and radiological profile of a series of PC and PG diagnosed in a Brazilian population. The files of two Oral Pathology laboratories were reviewed and all cases diagnosed as PG and PC were selected for the study. Clinical and radiological information were retrieved and data were tabulated and descriptively and comparatively analyzed. Final sample was composed by 647 inflammatory periapical lesions, including 244 PG (38%) and 403 PC (62%). The number of women affected by PG was significantly higher than the number of women affected by PC (p=0.037). Anterior region of the maxilla was the most common affected area for both entities (39% of the cases), but the most common anatomical location of PG (anterior maxilla and posterior maxilla) was different from PC (anterior maxilla and posterior mandible) (pincisor was the most affected tooth. The mean radiological size of the PC was larger than the mean radiological size of the PG (pcyst, radicular cyst, diagnosis, Oral Pathology.

  3. How to Diagnose and Classify Tattoo Complications in the Clinic: A System of Distinctive Patterns.

    Serup, Jørgen

    2017-01-01

    Tattoo complications represent a broad spectrum of clinical entities and disease mechanisms. Infections are known, but chronic inflammatory reactions have hitherto been inconsistently reported and given many interpretations and terms. A clinical classification system of distinct patterns with emphasis on inflammatory tattoo reactions is introduced. Allergic reactions prevalent in red tattoos and often associated with azo pigments are manifested as the 'plaque elevation', 'excessive hyperkeratosis', and 'ulceronecrotic' patterns. The allergen is a hapten. Nonallergic reactions prevalent in black tattoos and associated with carbon black are manifested as the 'papulonodular' pattern. Carbon black nanoparticles agglomerate in the dermis over time forming foreign bodies that elicit reactions. Many black tattoos even develop sarcoid granuloma, and the 'papulonodular' pattern is strongly associated with sarcoidosis affecting other organs. Tattoo complications include a large group of less frequent but nevertheless specific entities, i.e. irritant and toxic local events, photosensitivity, urticaria, eczematous rash due to soluble allergen, neurosensitivity and pain syndrome, lymphopathies, pigment diffusion or fan, scars, and other sequels of tattooing or tattoo removal. Keratoacanthoma occurs in tattoos. Carcinoma and melanoma are rare and occur by coincidence only. Different tattoo complications require different therapeutic approaches, and precise diagnosis is thus important as a key to therapy. The proposed new classification with characteristic patterns relies on simple tools, namely patient history, objective findings, and supplementary punch biopsy. By virtue of simplicity and broad access, these methods make the proposed classification widely applicable in clinics and hospitals. The system is reported to the 11th revision of the WHO diagnosis classification used as international standard. © 2017 S. Karger AG, Basel.

    Mortality in children with severe acute malnutrition (SAM) remains high despite standardized rehabilitation protocols. Two forms of SAM are classically distinguished: kwashiorkor and marasmus. Children with kwashiorkor have nutritional edema and metabolic disturbances, including hypoalbuminemia and hepatic steatosis, whereas marasmus is characterized by severe wasting. The metabolic changes underlying these phenotypes have been poorly characterized, and whether homeostasis is achieved during hospital stay is unclear. We aimed to characterize metabolic differences between children with marasmus and kwashiorkor at hospital admission and after clinical stabilization and to compare them with stunted and nonstunted community controls. We studied children aged 9-59 mo from Malawi who were hospitalized with SAM (n = 40; 21 with kwashiorkor and 19 with marasmus) or living in the community (n = 157; 78 stunted and 79 nonstunted). Serum from patients with SAM was obtained at hospital admission and 3 d after nutritional stabilization and from community controls. With the use of targeted metabolomics, 141 metabolites, including amino acids, biogenic amines, acylcarnitines, sphingomyelins, and phosphatidylcholines, were measured. At admission, most metabolites (128 of 141; 91%) were lower in children with kwashiorkor than in those with marasmus, with significant differences in several amino acids and biogenic amines, including those of the kynurenine-tryptophan pathway. Several phosphatidylcholines and some acylcarnitines also differed. Patients with SAM had profiles that were profoundly different from those of stunted and nonstunted controls, even after clinical stabilization. Amino acids and biogenic amines generally improved with nutritional rehabilitation, but most sphingomyelins and phosphatidylcholines did not. Children with kwashiorkor were metabolically distinct from those with marasmus, and were more prone to severe metabolic disruptions. Children with SAM showed

    We present the clinical history and the cognitive and behavioral presentations of a male patient with suspected progressive supranuclear palsy (PSP) who fatally shot himself in the head. We believe his act of suicide was the consequence of impulsivity, rather than primary depression or mood disturbance. In cases of suspected PSP and other atypical parkinsonisms, health professionals must be aware of neurobehavioral risk factors for suicide attempts and completions to promote patient safety; however, the literature on this topic is sparse. Our case highlights the potentially lethal consequences of impulsivity and other neuropsychiatric symptoms in PSP and related syndromes.

    Full Text Available Severe ovarian hyperstymulation syndrome is a rare but potentially life-threatening complication in patients undergoing assisted reproductive techniques (ART. The pathogenesis of this condition is likely to be multifactorial. The aim of the retrospective study was to present management in moderate and severe iatrogenic ovarian hyperstymulation syndrome (OHSS in clinical material. The study group was 19 women, admitted to the Department of Obstetrics and Gynecology in Central Clinical Hospital of Ministry of Interior and Administration in Warsaw from large outpatient infertility center "Novum" in Warsaw with moderate and severe OHSS between 14.07.2004 and 8.11.2005. Laboratory tests and ultrasound examination of the ovarian size and ascites were performed, abdominal circumference was measured. Patients were treated with rehydration with intravenous crystalloids and colloids, diuretics, antibiotics, anticoagulants and ultrasound-guided paracentesis if symptoms of ascites become severe (ascites causes pain and compromised pulmonary function. Oral intake of water was restricted, monitoring of fluid intake and output, and daily monitoring of body weight was performed. During treatment controlled laboratory tests were done. In one patient occurred intra-abdominal hemorrhage from ovarian rupture and laparotomy with oophorectomy was performed. The ovarian hyperstimulation syndrome is still a difficult diagnostic and therapeutic problem and more studies are required to elucidate pathophysiology of OHSS. Because of still unknown etiology treatment is empirical and in most of cases bases on experience of medical team. Thus, the management in individual patients varies according to the severity of ovarian hyperstymulation syndrome and its complications.

    Acute disseminated encephalomyelitis (ADEM) and multiple sclerosis (MS) are both CNS inflammatory demyelinating diseases with overlapping clinical features. A case is reported of a 51-year-old female who presented with headache, progressive aphasia and hemiparesis without preceding infection or vaccination. Brain MRI revealed multiple, often confluent, subcortical white matter lesions without enhancement, affecting predominantly the left cerebral hemisphere. CSF examination failed to reveal oligoclonal bands. Brain biopsy revealed both pathological features of ADEM and findings are consistent with the early stage of MS, including meningeal B and T lymphocytic infiltration, perivenular demyelination, subpial demyelination and discrete confluent plaque-like foci of demyelination. Steroid treatment resulted in remarkable clinical and radiological improvement and there has been no recurrence in six years of follow-up. This case highlights the difficulties in differentiating between ADEM and the first attack of MS and further suggests that ADEM and the early stage of MS, and its tumefactive variant, may have a common underlying pathologic mechanism, which may have a therapeutic implication in treating these diseases.

    2014-01-01

    Full Text Available Overgrowth syndromes comprise a heterogeneous group of diseases that are characterized by excessive tissue development. Some of these syndromes may be associated with dysfunction in the receptor tyrosine kinase (RTK/PI3K/AKT pathway, which results in an increased expression of the insulin receptor. In the current review, four overgrowth syndromes were characterized (Proteus syndrome, Klippel-Trenaunay-Weber syndrome, Madelung’s disease, and neurofibromatosis type I and illustrated using cases from our institution. Because these syndromes have overlapping clinical manifestations and have no established genetic tests for their diagnosis, radiological methods are important contributors to the diagnosis of many of these syndromes. The correlation of genetic discoveries and molecular pathways that may contribute to the phenotypic expression is also of interest, as this may lead to potential therapeutic interventions.

    To determine the most accurate, noninvasive method of assessing dehydration. The following data sources were searched: electronic databases, gray literature, scientific meetings, reference lists, and authors of unpublished studies. Eligible studies were comparative outpatient evaluations that used an accepted reference standard and were conducted in developed countries in children aged extraction was completed independently by multiple reviewers before a consensus was made. Nine studies that included 1039 participants were identified. The 4-item Clinical Dehydration Scale (CDS), the "Gorelick" score, and unstructured physician assessment were evaluated in 3, 2, and 5 studies, respectively. Bedside ultrasound, capillary digital videography, and urinary measurements were each evaluated in one study. The CDS had a positive likelihood ratio (LR) range of 1.87-11.79 and a negative LR range of 0.30-0.71 to predict 6% dehydration. When combined with the 4-item Gorelick Score, the positive LR was 1.93 (95% CI 1.07-3.49) and negative LR was of 0.40 (95% CI 0.24-0.68). Unstructured dehydration assessment had a pooled positive LR of 2.13 (95% CI 1.33-3.44) and negative LR of 0.48 (95% CI 0.28-0.82) to detect ≥ 5% dehydration. Overall, the clinical scales evaluated provide some improved diagnostic accuracy. However, test characteristics indicate that their ability to identify children both with and without dehydration is suboptimal. Current evidence does not support the routine use of ultrasound or urinalysis to determine dehydration severity. Copyright © 2015 Elsevier Inc. All rights reserved.

  11. Auto-antibodies and their association with clinical findings in women diagnosed with microscopic colitis.

    Directory of Open Access Journals (Sweden)

    Bodil Roth

    Full Text Available BACKGROUND: Microscopic colitis (MC is a disease manifested by diarrhoea and is divided into collagenous and lymphocytic colitis. The aetiology is unknown, but auto-immunity is suggested. Auto-antibodies have been only rarely examined in this entity. The aim of the study was to examine the prevalence of auto-antibodies, and to examine associations between the presence of antibodies and clinical findings. METHODS AND FINDINGS: Women with MC verified by biopsy and younger than 73 years, at any Department of Gastroenterology, in the district of Skåne, between 2002 and 2010 were invited to participate in this study. The patients were asked to complete both a questionnaire describing their medical history and the Gastrointestinal Symptom Rating Scale (GSRS. Blood samples were collected. Anti-nuclear antibodies (ANA, anti-neutrophil cytoplasmic antibodies (ANCA, anti-Saccharomyces cerevisiae antibodies (ASCA, and antibodies against glutamic acid decarboxylase (anti-GAD, islet antigens-like insulin 2 (anti-IA2, thyroid peroxidase (anti-TPO, and thyrotropin receptor (TRAK were analysed. Of 240 women identified, 133 were finally included in the study, median age 63 (59-67 years. Apart from the MC diagnosis, 52% also suffered from irritable bowel syndrome, 31% from hypertension and 31% from allergy. The prevalence of ANA (14%, ASCA IgG (13%, and anti-TPO antibodies (14% for these patients was slightly higher than for the general population, and were found together with other concomitant diseases. Patients had more of all gastrointestinal symptoms compared with norm values, irrespective of antibody expression. CONCLUSIONS: Women with MC have a slightly increased prevalence of some auto-antibodies. These antibodies are not associated with symptoms, but are expressed in patients with concomitant diseases, obscuring the pathophysiology and clinical picture of MC.

    Full Text Available Objective: To investigate possible mitochondrial DNA (mtDNA mutations in patients with Leber’s hereditary optic neuropathy (LHON in order to provide a precise diagnosis and genetic counseling.Material and Methods: Between 1982 and 2007, ten patients were clinically diagnosed with LHON and six of these patients agreed to be involved in this study. Six healthy individuals were also included as a control group. mtDNA was isolated from peripheral blood samples and polymerase chain reaction and mtDNA sequence analysis were performed. Results: In one of the six patients, a homoplasmic mutant m.11778G>A mutation was detected. All of the clinically diagnosed LHON patients and the control groups had the m.14212C>T and m.14580G>A single nucleotide polymorphisms (SNPs. The m.11719A>G SNP was detected in three of six patients and four of the controls. Two of the six patients had the m.3197T>C SNP and, in addition, the m.14258G>A SNP was found in one of these two patients, while neither of these mutations were present in the control group.Conclusion: The clinical diagnosis of LHON could be supported by molecular genetics only in one patient by the detection of one mutation. The m.3197T>C and m.14258G>A SNPs should be considered as potential mtDNA mutations due to the fact that they were detected in the patient group. These mutations should be investigated further in large case groups for suspected gene loci that could lead to optic neuropathy.

    An optical fiber probe for multimodal spectroscopy was designed, developed and used for tissue diagnostics. The probe, based on a fiber bundle with optical fibers of various size and properties, allows performing spectroscopic measurements with different techniques, including fluorescence, Raman, and diffuse reflectance, using the same probe. Two visible laser diodes were used for fluorescence spectroscopy, a laser diode emitting in the NIR was used for Raman spectroscopy, and a fiber-coupled halogen lamp for diffuse reflectance. The developed probe was successfully employed for diagnostic purposes on various tissues, including brain and bladder. In particular, the device allowed discriminating healthy tissue from both tumor and dysplastic tissue as well as to perform tumor grading. The diagnostic capabilities of the method, determined using a cross-validation method with a leave-one-out approach, demonstrated high sensitivity and specificity for all the examined samples, as well as a good agreement with histopathological examination performed on the same samples. The obtained results demonstrated that the multimodal approach is crucial for improving diagnostic capabilities with respect to what can be obtained from individual techniques. The experimental setup presented here can improve diagnostic capabilities on a broad range of tissues and has the potential of being used clinically for guiding surgical resection in the near future.

    In this study, we propose an automated otoscopy image analysis system called Autoscope. To the best of our knowledge, Autoscope is the first system designed to detect a wide range of eardrum abnormalities by using high-resolution otoscope images and report the condition of the eardrum as "normal" or "abnormal." In order to achieve this goal, first, we developed a preprocessing step to reduce camera-specific problems, detect the region of interest in the image, and prepare the image for further analysis. Subsequently, we designed a new set of clinically motivated eardrum features (CMEF). Furthermore, we evaluated the potential of the visual MPEG-7 descriptors for the task of tympanic membrane image classification. Then, we fused the information extracted from the CMEF and state-of-the-art computer vision features (CVF), which included MPEG-7 descriptors and two additional features together, using a state of the art classifier. In our experiments, 247 tympanic membrane images with 14 different types of abnormality were used, and Autoscope was able to classify the given tympanic membrane images as normal or abnormal with 84.6% accuracy.

Patients were divided into 2 groups basing on time period after completion of the main treatment course. Group I – 32 patients (up to 6 months, group II – 63 patients (more than 6 months.Results of the study. Results of TRA tests in Group I remained positive in 34.4% of patients and in Group II - 23.8%. The average size of the induration in Group I made 10 mm(95% CI 6.5-13.3, in Group II – 13 mm (95% CI 8.4-19.7 Patients from Group I had positive results of TRA test more often in case of initial infiltrate form of pulmonary tuberculosis and bacillary excretion. In patients from Group II the positive TRA results correlated with presence of concurrent conditions and exposure to a tuberculosis case in the past. Positive results were confidently more often observed in lonely patients in both groups. TRA test can be a valuable tool to evaluate the risk of tuberculosis relapse after completion of the main treatment course.

    To quantitatively evaluate the diagnostic value of gemstone spectral CT in thyroid disease. A total of 123 patients with thyroid diseases were enrolled in the retrospective study. All the patients underwent spectral CT scan, and 39 of them underwent dual-phase enhanced scan. Iodine concentration (IC) and normalized IC (NIC) were compared between benign and malignant nodules. The optimal threshold to predict malignancy was obtained by receiver operating characteristic curve (ROC). Multivariate ROC analysis was performed to evaluate the efficacy of combining the IC (NIC) and conventional morphological characteristics. Ten diffuse diseases and 113 nodular diseases were confirmed by clinical laboratory examination and histopathology. In total, 122 nodules (87 benign and 35 malignant) were detected, 41 nodules in enhanced cases. The IC and NIC_{VP} of malignant nodules were significantly lower than benign nodules in noncontrast and venous phase (VP) (P=0.000). The optimal IC and NIC_{VP} threshold was 0.68 mg/mL and 0.38, achieving 74.3% and 76.9% sensitivity, 66.7% and 80.0% specificity, respectively. For multivariate analysis, the area under ROC (AUC) was 0.88 and 0.94 in noncontrast and VP, respectively. Sensitivities of 77.1% and 84.6%, and specificities of 84.5% and 88.0% were achieved. Gemstone spectral CT can generally evaluate the abnormal iodine content in thyroid disease. Lower iodine can help differentiating malignant from benign nodules. A comprehensive analysis combining spectrum parameters and morphological characteristics is suggested in differential diagnosis.

    Complex regional pain syndrome (CRPS), formerly known as reflex sympathetic dystrophy is a pain syndrome with an unclear pathophysiology and unpredictable clinical course. The disease is often therapy resistant, the natural course not always favorable. The diagnosis of CRPS is based on signs and symptoms derived from medical history and physical examination. Pharmacological pain management and physical rehabilitation of limb function are the main pillars of therapy and should be started as early as possible. If, however, there is no improvement of limb function and persistent severe pain, interventional pain management techniques may be considered. Intravenous regional blocks with guanethidine did not prove superior to placebo but frequent side effects occurred.Therefore this technique receives a negative recommendation (2 A-). Sympathetic block is the interventional treatment of first choice and has a 2 B+ rating. Ganglion stellatum (stellate ganglion) block with repeated local anesthetic injections or by radiofrequency denervation after positive diagnostic block is documented in prospective and retrospective trials in patients suffering from upper limb CRPS. Lumbar sympathetic blocks can be performed with repeated local anesthetic injections. For a more prolonged lumbar sympathetic block radiofrequency treatment is preferred over phenol neurolysis because effects are comparable whereas the risk for side effects is lower (2 B+). For patients suffering from CRPS refractory to conventional treatment and sympathetic blocks, plexus brachialis block or continuous epidural infusion analgesia coupled with exercise therapy may be tried (2 C+). Spinal cord stimulation is recommended if other treatments fail to improve pain and dysfunction (2 B+). Alternatively peripheral nerve stimulation can be considered, preferentially in study conditions (2 C+). © 2010 The Authors. Pain Practice © 2010 World Institute of Pain.

    To analyze indications for early palliative radiation therapy (RT) (ie, start within 1 month from cancer diagnosis), regimens used in clinical practice, rate of treatment completion and treatment in the last 30 days of life, and overall survival. Retrospective uni- and multivariate analyses covering a 4.5-year inclusion period. Seventeen percent of all palliative RT courses were administered in the specified time frame (n = 100 patients, 30 Gy in 10 fractions in 49%). Common indications were bone and brain metastases, whereas metastatic spinal cord compression or other emergencies comprised a minority. Only 14% of patients had no distant metastases. Most patients had non-small cell lung cancer (51%), whereas other high-incidence primary tumors such as breast, prostate, and colorectal cancer combined comprised 10%. Failure to complete RT occurred in 6%. Median survival was 3.6 months. A startling high rate of RT in the last 30 days of life was observed (19%). Risk correlated significantly with performance status and extent of metastatic disease. The study population of patients who received early palliative RT is not identical to the general population described in previous studies, which covered the entire disease trajectory. Median survival was relatively short and rate of RT in the last 30 days of life higher than expected. Need for early palliative RT might be caused by large symptom burden and/or contraindication(s) for other management options, and might in many cases also be associated with adverse prognostic features and aggressive disease.

    BACKGROUND: According to the existing literature on infertility, stress appears to be inevitably associated with infertility diagnosis and treatment in sub-fertile individuals. The epidemiological data on the prevalence and predictors of infertility-specific stress in cultural specific scenario are scarce. The objective of the present study was to estimate the prevalence of infertility-specific stress and identify predictors of infertility-specific stress in women diagnosed with primary infertility. MATERIALS AND METHODS: This cross-sectional study was conducted on 300 infertile married women, diagnosed with primary infertility. The tools used for the assessment were “semi-structured questionnaire” compiled by the authors, “ICD-10 Classification of Mental and Behavioral Disorders (Clinical Descriptions and Diagnostic Guidelines),” and “Psychological Evaluation Test for infertility.” STATISTICAL ANALYSIS: Data were analyzed using SPSS (version 15). Chi-square test was used for univariate analysis followed by multiple logistic regressions between stress and the predictor variables. RESULTS AND DISCUSSION: The prevalence of stress among women was 80%. Univariate analysis revealed that predictors of stress were years of marital life, duration of infertility, infertility type, history of gynecological surgery, cycles of ovulation induction with timed intercourse and intra-uterine inseminations, present and past psychiatric morbidity, coping difficulties, gynecological diagnosis, and severity of premenstrual dysphoria. Multivariate analysis showed leading associations of stress with infertility type and coping difficulties. PMID:27110075

    Despite the persistently high HIV-related mortality in sub-Saharan Africa, limited information on the causes of death is available. Pathological autopsies are the gold standard to establish causes of death. In this review we describe the autopsy series performed among HIV-infected individuals in sub-Saharan Africa over the last two decades. We identified nine complete and 11 partial or minimally invasive autopsy series. Complete autopsies were performed in 593 HIV-positive adults and 177 HIV-positive children. Postmortem diagnoses were mainly infectious diseases. Tuberculosis was the most frequent, present in 21-54% of HIV-positive adults and was considered the cause of death in 32-45%. Overall, pulmonary infections accounted for approximately 66% of pathology and central nervous system infections for approximately 20%. A high discordance between clinical and postmortem diagnoses was observed. This review emphasizes the need for reliable information on causes of death in order to improve HIV patient care, guide further research, and inform health policy.

    Sensorineural hearing loss must be considered within the clinical picture of systemic lupus erythematosus. The results confirm the usefulness of extended high-frequency audiometry in the audiologic testing of these patients, enabling the possibility of modifying or applying a preventive treatment for a possible hearing loss. Hearing involvement is usually under-diagnosed with routine auditory examination. This study proposes the use of extended high-frequency audiometry to achieve a correct detection of a possible asymptomatic hypoacusis in early stages of the disease. The aim of this study is to analyze the hearing levels in extended high-frequencies in these patients and to correlate the hearing loss with the severity of the disease and the immunological parameters. A descriptive cross-sectional study was performed. Fifty-five patients with systemic lupus erythematosus were included in the study. The control group consisted of 71 patients paired by age and sex with the study population. Both a pure tone audiometry and an extended high-frequency audiometry (8-18 KHz) were performed. In total, 70% were diagnosed with sensorineural hearing loss with extended high-frequency audiometry, overcoming the results obtained with pure tone audiometry (30.9%). Statistically significant correlations were found within the patients regarding sensorineural hearing loss related with age, disease activity and cryoglobulinemia.

Univariate analysis revealed that predictors of stress were years of marital life, duration of infertility, infertility type, history of gynecological surgery, cycles of ovulation induction with timed intercourse and intra-uterine inseminations, present and past psychiatric morbidity, coping difficulties, gynecological diagnosis, and severity of premenstrual dysphoria. Multivariate analysis showed leading associations of stress with infertility type and coping difficulties.

    This article critically examines the significance of relational approaches for sociological understandings of clinical interactions, relations and practices, by exploring the ways in which relational theories and concepts have been employed in the recent sociological accounts of clinical encounters to trouble the classical dyadic models of clinical interaction and the related atomistic conceptions of agency and accountability. Reading this work through the theoretical contributions from feminist science studies scholarship, and particularly the work of Donna Haraway and Karen Barad, the article proposes an alternative understanding of clinical interactions, relations and practices, where relations are conceived as constitutive of individuals (objects/bodies and their attributes/identities), rather than being constituted by encounters between individuals. Key for this understanding is the reconceptualisation of clinical encounter as an apparatus of bodily production through which different agents (patients, clinicians, diseases and healthcare services) are materialised and enacted.

    To examine similarities and differences in urine drug test (UDT) results in clinical pain patients and pain subjects participating in pain research studies. An observational study with retrospective chart review and data analysis. We analyzed 1,874 UDT results obtained from 1) clinical pain patients (Clinical Group; n = 1,529) and 2) pain subjects consented to participate in pain research studies (Research Group; n = 345). Since several medications such as opioids used in pain management are drugs of abuse (DOA) and can result in a positive UDT, we specifically identified those cases of positive UDT due to nonprescribed DOA and designated these cases as positive UDT with DOA (PUD). We found that 1) there was a higher rate of PUD in clinical pain patients (41.3%) than in pain research study subjects (14.8%); 2) although subjects in the Research Group were informed ahead of time that UDT will be conducted as a screening test, a substantial number (14.8%) of pain research study subjects still showed PUD; 3) there were different types of DOA between clinical pain patients (cannabinoids as the top DOA) and research study subjects (cocaine as the top DOA); and 4) a common factor associated with PUD was opioid therapy in both Clinical Group and Research Group. These results support previous findings that PUD is a common finding in clinical pain patients, particularly in those prescribed opioid therapy, and we suggest that UDT be used as routine screening testing in pain research studies. © 2015 American Academy of Pain Medicine.

    We sought to characterize dengue virus (DENV) infections among febrile children enrolled in a pediatric cohort study who were clinically diagnosed with a non-dengue illness ("C cases"). DENV infections were detected and viral load quantitated by real-time reverse transcription-polymerase chain reaction in C cases presenting between January 2007 and January 2013. One hundred forty-one of 2892 C cases (4.88%) tested positive for DENV. Of all febrile cases in the study, DENV-positive C cases accounted for an estimated 52.0% of patients with DENV viremia at presentation. Compared with previously detected, symptomatic dengue cases, DENV-positive C cases were significantly less likely to develop long-lasting humoral immune responses to DENV, as measured in healthy annual serum samples (79.7% vs 47.8%; P dengue. These findings have important implications for DENV transmission modeling, immunology, and epidemiologic surveillance.

    2013-01-01

    Background The features of carotid atherosclerosis in ketosis-onset diabetes have not been investigated. Our aim was to evaluate the prevalence and clinical characteristics of carotid atherosclerosis in newly diagnosed Chinese diabetic patients with ketosis but without islet-associated autoantibodies. Methods In total, 423 newly diagnosed Chinese patients with diabetes including 208 ketosis-onset diabetics without islet-associated autoantibodies, 215 non-ketotic type 2 diabetics and 79 control subjects without diabetes were studied. Carotid atherosclerosis was defined as the presence of atherosclerotic plaques in any of the carotid vessel segments. Carotid intima-media thickness (CIMT), carotid atherosclerotic plaque formation and stenosis were assessed and compared among the three groups based on Doppler ultrasound examination. The clinical features of carotid atherosclerotic lesions were analysed, and the risk factors associated with carotid atherosclerosis were evaluated using binary logistic regression in patients with diabetes. Results The prevalence of carotid atherosclerosis was significantly higher in the ketosis-onset diabetic group (30.80%) than in the control group (15.2%, p=0.020) after adjusting for age- and sex-related differences, but no significant difference was observed in comparison to the non-ketotic diabetic group (35.8%, p=0.487). The mean CIMT of the ketosis-onset diabetics (0.70±0.20 mm) was markedly higher than that of the control subjects (0.57±0.08 mm, pketosis-onset and the non-ketotic diabetes, the prevalence of carotid atherosclerosis was markedly increased with age (both pketosis-onset diabetics, the presence of carotid atherosclerosis was significantly associated with age, hypertension, low-density lipoprotein cholesterol and mean CIMT. Conclusions The prevalence and risk of carotid atherosclerosis were significantly higher in the ketosis-onset diabetics than in the control subjects but similar to that in the non-ketotic type 2

    To clarify the usefulness of 3.0-T MR elastography (MRE) in diagnosing the histological grades of liver fibrosis using preliminary clinical data. Between November 2012 and March 2014, MRE was applied to all patients who underwent liver MR study at a 3.0-T clinical unit. Among them, those who had pathological evaluation of liver tissue within 3 months from MR examinations were retrospectively recruited, and the liver stiffness measured by MRE was correlated with histological results. Institutional review board approved this study, waiving informed consent. There were 70 patients who met the inclusion criteria. Liver stiffness showed significant correlation with the pathological grades of liver fibrosis (rho = 0.89, p < 0.0001, Spearman's rank correlation). Areas under the receiver operating characteristic curve were 0.93, 0.95, 0.99 and 0.95 for fibrosis score greater than or equal to F1, F2, F3 and F4, with cut-off values of 3.13, 3.85, 4.28 and 5.38 kPa, respectively. Multivariate analysis suggested that grades of necroinflammation also affected liver stiffness, but to a significantly lesser degree as compared to fibrosis. 3.0-T clinical MRE was suggested to be sufficiently useful in assessing the grades of liver fibrosis.

    STUDY OBJECTIVE--To investigate the relationship between presenile dementia of the Alzheimer type (PDAT) and family history, medical history, cigarette smoking, and exposure to aluminum. DESIGN--A case-control study in which 109 cases of clinically diagnosed PDAT and 109 controls matched for age and sex were compared for exposure to the risk factors. Odds ratios (ORs) were calculated using McNemar's test. SETTING--The northern health region of England. PATIENTS--Cases comprised those under 65 years diagnosed as having dementia by specialist services, who met clinical algorithm criteria for Alzheimer's disease (AD). Cases were confirmed at interview. MAIN RESULTS--Comparing cases with controls, (ORs) significantly greater than unity were obtained when there was a first degree relative with dementia (OR 2.5, 95% confidence interval 1.05, 6.56), any relative with dementia (OR 2.1, 95% CI 1.01, 4.55), and any relative aged less than 65 with dementia (OR 8.0, 95% CI 1.07, 348). Exposure to moderate levels of cigarette smoking (cumulative) was not significant; nor was exposure to aluminum in drinking water, diet, and medicinal sources. CONCLUSION--In this study of modest statistical power, a family history of dementia was confirmed as a risk factor in PDAT. No significant relationship between exposure to aluminium in water supplies, tea, and antacids was found. What is important, however, is the bioavailability of all dietary aluminium, determined by the concentrations of dissolved silicon in water: this requires further investigation. PMID:7629459

    Full Text Available Abstract Background At diabetes diagnosis major decisions about life-style changes and treatments are made based on characteristics measured shortly after diagnosis. The predictive value for mortality of these early characteristics is widely unknown. We examined the predictive value of patient characteristics measured shortly after diabetes diagnosis for 5-year all-cause and cardiovascular mortality with special reference to self-rated general health. Methods Data were from a population-based sample of 1,323 persons newly diagnosed with clinical diabetes and aged 40 years or over. Possible predictors of mortality were investigated in Cox regression models. Results Multivariately patients who rated their health less than excellent experienced increased all-cause and cardiovascular mortality. These end-points also increased with sedentary life-style, relatively young age at diagnosis and presence of cardiovascular disease (CVD at diagnosis. Further predictors of all-cause mortality were male sex, low body mass index and cancer, while cardiovascular mortality increased with urinary albumin concentration. Conclusions We found that patients who rated their health as less than excellent had increased 5-year mortality, similar to that of patients with prevalent CVD, even when biochemical, clinical and life-style variables were controlled for. This finding could motivate doctors to discuss perceptions of health with newly diagnosed diabetic patients and be attentive to patients with suboptimal health ratings. Our findings also confirm that life-style changes and optimizing treatment are particularly relevant for relatively young and inactive patients and those who already have CVD or (microalbuminuria at the time of diabetes diagnosis.

    A discussion forum was hosted by the German not-for-profit Association for Applied Human Pharmacology (AGAH e.V.) to critically review key eligibility criteria and stopping rules for clinical trials with healthy subjects, enrolling stakeholders from the pharmaceutical industry, contract research organisations, academia, ethics committees and competent authority. Pivotal eligibility criteria were defined for trials with new investigational medicinal products (IMPs) or with clinically established IMPs. In general, a pulse rate ranging between 50 and 90 beats/min is recommended for first-in-human (FIH) trials, while wider ranges seem acceptable for trials with clinically established IMPs, provided there are no indications of thyroid dysfunction. Hepatic laboratory parameters not to exceed the upper limit of normal (ULN) comprise ALT (alanine aminotransferase) and AST (aspartate aminotransferase) in FIH trials, whereas slight elevations (10% above ULN) seem acceptable in trials with clinically established IMPs without known hepatotoxicity. A normal renal function is required for any clinical trial in healthy subjects. A risk-adapted approach for stopping rules was adopted. Stopping rules for an individual subject are one adverse event of severe intensity or one serious adverse event. In case of a severe adverse event, some stakeholders demand a causal relationship with the IMP (i.e. an adverse reaction). Stopping rules for a cohort are one serious adverse reaction or ≥50% of subjects experiencing any adverse reaction of moderate or severe intensity. The application of this consensus resulted in a reduction in protocol deficiencies issued by the competent authority.

  18. Subjectivity in clinical practice: on the origins of psychiatric semiology in early French alienism.

    Science.gov (United States)

    Huertas, Rafael

    2014-12-01

    The aim of this article is to contribute to the analysis of the origins of psychiatric semiology, which by emphasizing subjectivity in clinical practice, gave birth to psychopathology as the scientific and intellectual enterprise of alienism. In other words, beyond simple anatomical and clinical observation, there was an effort to 'listen to' and 'read' the patient's delirium. In essence, the basic thesis which this short paper seeks to defend is that, despite a growing anatomical and clinical mind-set and a clear interest in physically locating mental illness within the body, during the Romantic period, psychiatry was able to construct a semiology largely based on the experience of the ego, on the inner world of the individual. This makes it possible to establish, from a clinical perspective, that the birth of alienism - of psychiatry - must be situated within the framework of a modernity in which the culture of subjectivity was one of its most characteristic features. © The Author(s) 2014.

    Current recommendations for evaluation and diagnosis of attention-deficit hyperactivity disorder (ADHD) are meant for primary care settings and may not adequately address the needs of children seen in subspecialty developmental-behavioral pediatric settings who may have higher rates of comorbid developmental, learning, and psychiatric disorders. The authors sought to characterize the diagnostic complexity of school-aged children diagnosed with ADHD after comprehensive multidisciplinary evaluation in a subspecialty developmental-behavioral pediatric clinic. The authors conducted a retrospective medical record review of 144 patients aged 7 to 11 years who were consecutively evaluated by an interdisciplinary team (developmental-behavioral pediatrician, psychologist, educator) in a school-age clinic within a developmental-behavioral pediatrics tertiary care center from January 1, 2009 to December 31, 2009. After comprehensive evaluation, rates of ADHD diagnosis increased from 32.6% (n = 47) preevaluation to 54.2% (n = 78) postevaluation (p pediatric subspecialty setting, a comprehensive evaluation including developmental, neuropsychological, and educational assessments yielded high rates of comorbid psychiatric, developmental, and learning disorders. This supports the need to provide comprehensive interdisciplinary assessment for such children to ensure the identification and treatment of not only the core symptoms of ADHD but also the comorbidities that may otherwise go unrecognized and therefore not optimally treated.

    To evaluate the validity of recorded diagnoses of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) in the Clinical Practice Research Datalink (CPRD). We identified patients with a diagnosis of SJS or TEN between 1995 and 2013 in the CPRD. We reviewed information from patient records, free text, and hospital episode statistics (HES) data, and excluded patients with no indication of a secondary care referral. Remaining patients were classified as probable, possible, or unlikely cases of SJS/TEN by two specialised clinicians or based on pre-defined classification criteria. We quantified positive predictive values (PPV) for all SJS/TEN patients and for patients categorised as 'probable/possible' cases of SJS/TEN, based on a representative subsample of 118 patients for whom we had unequivocal information (original discharge letters or HES data). We identified 1324 patients with a diagnosis of SJS/TEN, among whom 638 had a secondary care referral recorded. Of those, 565 were classified as probable or possible cases after expert review. We calculated a PPV of 0.79 (95% CI, 0.71-0.86) for all SJS/TEN patients with a recorded secondary care referral, and a PPV of 0.87 (95% CI, 0.81-0.93) for probable/possible cases. After excluding 14 false positive patients, our study population consisted of 551 SJS/TEN patients. Diagnoses of SJS/TEN are recorded with moderate diagnostic accuracy in the CPRD, which was substantially improved by additional expert review of all available information. We established a large population-based SJS/TEN study population of high diagnostic validity from the CPRD. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    The aim of this study was to describe nurse leaders' perceptions of ethical recruitment in clinical research. Nurse leaders are expected to get involved in clinical research, but there are few studies that focus on their role, particularly the ethical issues. Qualitative data were collected from ten nurse leaders using thematic one-to-one interviews and analysed with content analysis. Nurse leaders considered clinical research at their workplace in relation to the key issues that enabled ethical recruitment of study subjects in clinical research. These were: early information and collaboration for incorporating clinical research in everyday work, an opportune and peaceful recruitment moment and positive research culture. Getting involved in clinical research is part of the nurse leader's professional responsibility in current health care. They have an essential role to play in ensuring that recruitment is ethical and that the dignity of study subjects is maintained. The duty of nurse leaders is to maintain good contact with other collaborators and to ensure good conditions for implementing clinical research at their site. This requires a comprehensive understanding of the overall situation on their wards. Implementing clinical research requires careful planning, together with educating, supporting and motivating nursing staff. © 2014 John Wiley & Sons Ltd.

    The objectives of this study are threefold: 1) to examine the effect of frequency of head motion on the clinical dynamic visual acuity (DVA) score in subjects with unilateral vestibular hypofunction (UVH); 2) to compare DVA scores between subjects with UVH and subjects with a complete unilateral vestibular deficit; and 3) to establish whether a relationship exists between the extent of the vestibular deficit and the DVA score. Experimental study. Vestibular outpatient rehabilitation program. A convenience sample of 10 subjects with UVH. Dynamic visual acuity scores were recorded using 2 standard acuity charts: Snellen and E-chart. The DVA scores were obtained at slow (0.5 Hz), moderate (1 and 1.5 Hz), and fast (2.0 Hz) frequencies of head motion in the horizontal and the vertical planes. Percentage of caloric weakness was compared with DVA scores in each subject to test whether a relationship exists between the two. As the frequency of head motion increased, the number of UVH subjects with an abnormal DVA score increased. Subjects with an abnormal DVA score at 1 Hz had the same or higher score as the frequency of the head motion was increased. Spearman correlation analyses revealed low-correlation coefficients between percentage of vestibular paresis at the caloric test and DVA scores (horizontal direction: r = 0.31, p = 0.38 for Snellen chart and r = -0.33, p = 0.35 for the E-chart; vertical: r = 0.05, p = 0.91 for the Snellen chart and r = -0.28, p = 0.50 for the E-chart). Subjects with UVH manifest impaired DVA. The frequency of head motion has an impact on clinical DVA scores in UVH subjects.

    Subjective measures of performance were assessed on three different hearing aid circuits as part of a large clinical trial. These measurements included the Profile of Hearing Aid Performance and a subjective ranking of individual preference. A multi-center, double-masked clinical trial of hearing aids was conducted at eight VA Medical Centers. Three hearing aid circuits, a linear peak-clipper, a linear compression limiter and a wide dynamic range compressor, were investigated. The experimental design was a three-period, three-treatment crossover design. Subjects (N = 360) were stratified by site and randomized to one of six sequences for the hearing aid circuits. All fittings were binaural and involved a 3-mo trial with each of the three circuits. All subjective measures were administered for unaided and aided conditions at the end of each trial period. While all of the circuits resulted in improved scores on the aided versus the unaided PHAP, there were few conditions in which one circuit outperformed the others. An exception was the aversiveness of sound subscale where the peak clipper frequently scored worse than either the compression limiter or the wide dynamic range compressor. In the subjective ranking scale the compression limiter received more first place rankings than the other two circuits, especially for one subgroup of patients with moderate flat hearing loss. All circuits were perceived as beneficial by these subjects in most situations. The peak clipper scored worse on aversiveness of sound than did the other two circuits for most subjects, while the compression limiter seemed to have a slight advantage in subjective rankings. Most subjects perceived considerable aided benefit in situations involving background noise and reverberation, situations where hearing aid benefit is often questioned.

    To describe the clinical, histological, and immunohistochemical manifestations of canine necrotizing scleritis. A retrospective examination of the clinical records and samples of ocular tissues from five dogs with a histological diagnosis 'necrotizing scleritis' was completed. Archived, formalin-fixed, paraffin-embedded samples and two control globes were stained with hematoxylin and eosin, Gram, periodic acid-Schiff (PAS) and Masson trichrome stains, and they were immunohistochemically labeled for CD3, CD18, and CD20. Of the five cases reviewed, only two could be confirmed as idiopathic necrotizing scleritis. The other three cases were retrospectively diagnosed as unilateral focal, non-necrotizing scleritis, one as episcleritis and the third was scleritis secondary to a proptosed globe based on our retrospective clinical, histological, and immunohistochemical evaluations. In these two cases, idiopathic necrotizing scleritis manifested as a bilateral, progressive, inflammatory disease of the sclera and cornea that induces significant uveitis. Light microscopic examination confirmed collagen degeneration and granulomatous inflammation. There was no evidence for an infectious etiology based on Gram's and PAS stainings. Immunohistochemical labeling revealed a predominance of B cells in idiopathic, bilateral necrotizing scleritis. Tinctorial staining abnormalities with Masson's trichrome stain were present in scleral collagen of the two cases with idiopathic necrotizing scleritis as well as a case of secondary traumatic scleritis. Based on a limited number of cases, idiopathic canine necrotizing scleritis shares similar histopathological features with non-necrotizing scleritis and episcleritis; however, necrotizing scleritis is B-cell-dominated and bilateral, and significant collagen alterations manifest with Masson's trichrome stain. © 2011 American College of Veterinary Ophthalmologists.

    Pharmaceutical sponsored clinical trials, formerly conducted predominantly in the United States and Europe, have expanded to emerging regions, including the Middle East. Our study explores factors influencing clinical trial privacy and confidentiality in the United Arab Emirates. Factors including concept familiarity, informed consent compliance, data access, and preservation, were analyzed to assess current practices in the Arab world. As the UAE is an emerging region for clinical trials, there is a growing need for regulations related to data confidentiality and subject privacy. Informational and decisional privacy should be viewed within the realms of Arab culture and religious background.

The mean age of the girls and boys was 10.8±4.9 and 8.5±4.7 years, respectively. The most common age range was between 12 and 18 years. The proportion of patients who lived with both parents was 81.1%; however, the proportion of individuals brought in by institutional caregivers was 0.8%. The proportion of consanguineous marriages was 13.7%. The education level of mothers and fathers was mostly a primary school degree (47% and 45.6%, respectively. A positive psychiatric history was present in 13.7% of the mothers and 7.6% of the fathers. Reasons for child psychiatric assessments were as follows: 21.9% for disability report, 13.8% for forensic evaluation, 11.2% for consultation, and 52.9% for general psychiatric evaluation. Referral complaints were irritability/anger (15.7%, attention deficit/hyperactivity (14.8%, delay in speech (10.5%, fear/anxiety (5.9%, and poor school performance (5.7%. The diagnoses were as follows: attention deficit hyperactivity disorder (ADHD (20.6%, other disruptive behaviors (12.4%, and anxiety disorder (10.2%. CONCLUSION: We revealed that the most common referring complaint was irritability/anger and that the most common diagnosis was ADHD in our patient group, which was similar to previous studies. Our results showed that a low parental educational level and a positive history for parental psychopathology were

    Full Text Available Objective: To assess Mycobacterium tuberculosis (M. tuberculosis strains exsisting in Gedeo zone and the surrounding areas of the Southern Ethiopia using spoligotyping. Methods: A cross sectional study was carried out from February, 2012 to June, 2013 and 97 (76 sputum and 21 fine needle aspirate samples were taken from tuberculosis diagnosed patients at Dilla University Referral Hospital and other private clinics. Culturing, region of difference (RD9 deletion typing and spoligotyping techniques were employed to isolate M. tuberculosis strains. Results: Growth of mycobacteria was observed in 35.1% (34/97. Speciation of isolates showed that 91.2% (31/34 of the isolates were M. tuberculosis. Further characterization led to the identification of 23 different spoligotype patterns of M. tuberculosis of which 61% and 39% displayed unique and cluster patterns, respectively. The most dominant shared type was spoligotype international type 53. Of the 23 strains, 12 have not been registered in the international spoligotyping database (SpolDB4. Seventy one percent of the strains belonged to the Euro-American lineage. Conclusions: This study revealed the existence of both genetically diverse and clustered M. tuberculosis strains from tuberculosis patients in the area, suggesting reactivation of infection and recent transmission, respectively. Molecular epidemiology of M. tuberculosis should be done nationwide in order to set appropriate control measures.

    The 22nd February 2011 Christchurch earthquake killed 185 people, injured over 8000, damaged over 100,000 buildings and on-going aftershocks maintained high anxiety levels. This paper examines the dose of exposure effect of earthquake damage assessments, earthquake intensity measures, liquefaction and lateral spreading on mood and anxiety disorders in Christchurch after this event. We hypothesise that such disorders are more likely to develop in people who have experienced greater exposure to these impacts within their neighborhood than others who have been less exposed, but also live in the city. For this purpose, almost all clinically diagnosed incident and relapsed cases in Christchurch in a 12 months period after the 2011 earthquake were analysed. Spatio-temporal cluster analysis shows that people living in the widely affected central and eastern parts after the 2010/11 earthquakes have a 23% higher risk of developing a mood or anxiety disorder than people living in other parts of the city. Generally, mood and anxiety-related disorders increase with closer proximity to damage from liquefaction and moderate to major lateral spreading, as well as areas that are more likely to suffer from damage in future earthquakes.

    2013-02-01

    Attenuated psychosis syndrome (APS) is being proposed for inclusion in Section III of DSM-5 for those impaired by subthreshold psychotic symptoms that are not better accounted for by another diagnosis and not meeting criteria for a psychotic disorder. The rationale is to identify patients who are at high risk for transition to a psychotic disorder in the near future. However, the potential impact of using this new diagnosis in routine clinical practice settings has not been carefully examined. As part of the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, a treatment-seeking psychiatric outpatient sample (n = 1,257) recruited from June 1997 to June 2002 completed a self-report measure of psychiatric symptoms and afterward were administered structured clinical interviews. For the current post hoc study, we investigated the prevalence rate of endorsing attenuated psychotic experiences to identify patients who could potentially meet criteria for APS. After the exclusion of those with lifetime DSM-IV psychotic disorders, psychotic experiences remained highly prevalent in the sample (28% reported at least 1 psychotic experience during the past 2 weeks), and rates were similar across all major DSM-IV diagnostic categories. Only 1 patient (0.08%) reported psychotic experiences but did not meet criteria for another current DSM disorder; however, this individual endorsed other nonpsychotic symptoms of greater severity. Psychotic experience endorsement was positively correlated with nearly all other nonpsychotic symptom domains, and multivariate analysis showed that general clinical severity predicted endorsement of psychotic experiences (P values < .001). We could not identify any patients who clearly met criteria for APS alone in our sample. Psychotic experiences appear to be common in outpatients and represent nonspecific indicators of psychopathology. Diagnosing APS in the community could result in high rates of false-positives or high

    Full Text Available Abstract Background Increasing antimicrobial resistance among the key pathogens responsible for community-acquired respiratory tract infections has the potential to limit the effectiveness of antibiotics available to treat these infections. Since there are regional differences in the susceptibility patterns observed and treatment is frequently empirical, the selection of antibiotic therapy may be challenging. PROTEKT, a global, longitudinal multicentre surveillance study, tracks the activity of telithromycin and comparator antibacterial agents against key respiratory tract pathogens. Methods In this analysis, we examine the prevalence of antibacterial resistance in 1,336 bacterial pathogens, isolated from adult and paediatric patients clinically diagnosed with acute bacterial sinusitis (ABS. Results and discussion In total, 58.0%, 66.1%, and 55.8% of S. pneumoniae isolates were susceptible to penicillin, cefuroxime, and clarithromycin respectively. Combined macrolide resistance and reduced susceptibility to penicillin was present in 200/640 (31.3 % of S. pneumoniae isolates (128 isolates were resistant to penicillin [MIC >= 2 mg/L], 72 intermediate [MIC 0.12–1 mg/L] while 99.5% and 95.5% of isolates were susceptible to telithromycin and amoxicillin-clavulanate, respectively. In total, 88.2%, 87.5%, 99.4%, 100%, and 100% of H. influenzae isolates were susceptible to ampicillin, clarithromycin, cefuroxime, telithromycin, and amoxicillin-clavulanate, respectively. In vitro, telithromycin demonstrated the highest activity against M. catarrhalis (MIC50 = 0.06 mg/L, MIC90 = 0.12 mg/L. Conclusion The high in vitro activity of against pathogens commonly isolated in ABS, together with a once daily dosing regimen and clinical efficacy with 5-day course of therapy, suggest that telithromycin may play a role in the empiric treatment of ABS.

    Nonspecific neck pain patients form a heterogeneous group with different musculoskeletal impairments. Classifying nonspecific neck pain patients into subgroups based on clinical characteristics might lead to more comprehensive diagnoses and can guide effective management. To establish consensus among a group of experts regarding the clinical criteria suggestive of a clinical dominance of 'articular', 'myofascial', 'neural', 'central' and 'sensorimotor control' dysfunction patterns distinguishable in patients with nonspecific neck pain. Delphi study. A focus group with 10 academic experts was organized to elaborate on the different dysfunction patterns discernible in neck pain patients. Consecutively, a 3-round online Delphi-survey was designed to obtain consensual symptoms and physical examination findings for the 5 distinct dysfunction patterns resulting from the focus group. A total of 21 musculoskeletal physical therapists from Belgium and the Netherlands experienced in assessing and treating neck pain patients completed the 3-round Delphi-survey. Respectively, 33 (response rate, 100.0%), 27 (81.8%) and 21 (63.6%) respondents replied to rounds 1, 2 and 3. Eighteen 'articular', 16 'myofascial', 20 'neural', 18 'central' and 10 'sensorimotor control' clinical indicators reached a predefined ≥80% consensus level. These indicators suggestive of a clinical dominance of 'articular', 'myofascial', 'neural', 'central', and 'sensorimotor control' dysfunction patterns may help clinicians to assess and diagnose patients with nonspecific neck pain. Future validity testing is needed to determine how these criteria may help to improve the outcome of physical therapy interventions in nonspecific neck pain patients. Copyright © 2016 Elsevier Ltd.

    To compare two strategies of consent requirement (classical informed consent and randomised consent according to Zelen), the Clinical Data Elaboration Centre of South Italy, within the special project Clinical Application of Oncological Research of the National Research Council of Italy (CNR-ACRO) invited healthy people visiting the 7th edition of the scientific exhibition "Futuro Remoto" to simulate of being ill and receiving the offer of entering a clinical trial. Within informed consent strategy patients are asked to agree to the randomisation process, while, in the randomised consent, randomised treatment assignment is performed before consent requirement and patients should agree directly to the assigned therapy. Major aims of the study were (a) to compare the strategies in terms of refusal rate to a hypothetical clinical trial, and (b) to estimate whether severity of prognosis affected subjects' decision. 3,217 visiting people participated to the simulation; they were prevalently young, males and with a high level of school education. The study was performed in two different scenarios. In the first one, with one choice option, subject refusing consent could receive standard therapy only; refusal rate was 16% after informed consent and 13.4% after randomised consent (for experimental therapy). In the other scenario, with two choice options, subjects refusing consent could choose the preferred therapy; refusal rate was 20.6% after informed consent, 48.1% after randomised consent (for standard therapy) and 13.4% after randomised consent (for experimental therapy).(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available ABSTRACT: The aim of this study is to determine serum amyloid-A (SAA concentration in the cases of pneumonia, pneumoenteritis, and enteritis which are frequently encountered in calves in veterinary medicine. Although a great deal of experimental studies has been conducted in this field, studies on naturally infected calves are quite few. Eighty calves at the age of 0-6 months were used in the study and the calves were divided into four groups. Due to the clinical examination, the calves diagnosed with pneumonia (Group P; n=20, with pneumoenteritis (Group PE; n=20 and with enteritis (Group E; n=20 formed the disease group as the healthy ones formed the control (Group C; n=20 group. After the body temperatures of all calves were taken, blood samples were obtained from Jugular vein for haematological and biochemical measurements. As haematological, white blood cell (WBC, red blood cell (RBC, hemoglobin (Hb and hematocrit (Hct measurements were performed in Veterinary Hematology Analyzer. Serum amyloid-A (SAA, interleukin 1 (IL-1β, interleukin 6 (IL-6, tumor necrosis factor-α (TNF-α concentration measurements were carried out with ELISA reader by using commercial kits. Aspartate aminotransferase (AST, alanine aminotransferase (ALT, albumin (ALB, total bilirubin (T. Bil, total protein (TP, gamma glutamyltransferase (GGT, blood urea nitrogen (BUN concentration measurements were conducted in autoanalyzer by using commercial kits. In all disease groups (P, PE, and E body temperature, haematologic parameters (WBC, RBC, Hb and Hct, serum biochemical parameters (AST, ALT, ALB, T. Bil, TP, GGT and BUN, SAA concentration and serum concentrations of cytokines (IL-1β, IL-6 and TNF-α were determined to be higher in comparison to the control group (P<0.005. According to these findings, routine measurement of serum SAA concentration in veterinary medicine is considered to be beneficial in determining the severity of the disease, in selecting the proper

    Autism prevalence studies have often relied on administrative prevalence or clinical diagnosis as case-identification strategies. We report the incidence of clinical diagnoses of autism spectrum disorders (ASD), versus research-identified autism among residents of Olmsted County, Minnesota, age 1997. The incidence of clinically diagnosed ASD (with 95% CI) was 1.5 per 100,000 (0.0-3.7) in 1980-1983 and 33.1 (22.8-43.3) in 1995-1997, a 22.1-fold increase. In contrast, the incidence of research-identified autism increased from 5.5 (1.4-9.5) per 100,000 to 44.9 (32.9-56.9), an 8.2-fold increase. Only 46.8% of research-identified cases received a clinical diagnosis of ASD. These findings demonstrate the potential for misleading interpretation of results from epidemiologic studies that rely on clinical diagnosis of autism to identify cases.

    The inclusion of women in clinical trials has raised a variety of ethical and practical issues in their implementation. In the recent CAMELIA clinical trial in Cambodia, the inclusion criteria included a negative pregnancy test and signature of the consent form confirming commitment to double contraceptive use as patients were given drugs contra-indicated in case of pregnancy. But despite precautions and the requirement stated in the informed consent form, 19 out of 236 enrolled women became pregnant during the trial. The current paper describes the frictions and subjectivities that emerge as new medical technologies travel to resource-poor settings--and more specifically, how trial researchers, health workers, and research subjects involved in the CAMELIA trial negotiate the injunction to avoid pregnancy while using a teratogenic drug.

    There is a need for objective tools to help clinicians to diagnose Alzheimer's Disease (AD) early and accurately and to conduct Clinical Trials (CTs) with fewer patients. Magnetic Resonance Imaging (MRI) is a promising AD biomarker but no single MRI feature is optimal for all disease stages. Machine Learning classification can address these challenges. In this study, we have investigated the classification of MRI features from AD, Mild Cognitive Impairment (MCI), and control subjects from ADNI with four techniques. The highest accuracy rates for the classification of controls against ADs and MCIs were 89.2% and 72.7%, respectively. Moreover, we used the classifiers to select AD and MCI subjects who are most likely to decline for inclusion in hypothetical CTs. Using the hippocampal volume as an outcome measure, we found that the required group sizes for the CTs were reduced from 197 to 117 AD patients and from 366 to 215 MCI subjects.

    Clinical trials typically recruit subjects through referrals or media promotion, with generalizability of the results often uncertain. As part of a primary prevention trial to evaluate strategies for increasing physical activity in sedentary men and women, two recruitment sources, a random-digit-dial telephone survey and a community media campaign, were used to identify subjects. Baseline characteristics of 357 randomized men and women aged 50 to 65 years were compared by recruitment source. Whereas there were few differences between recruitment sources for demographic variables, telephone survey recruitment was particularly successful in recruiting smokers and persons with other cardiovascular risk factors into the trial. Counter to expectations, subsequent exercise adherence rates did not differ by recruitment source. The results suggest that the survey method, while more expensive, may be particularly useful for locating higher-risk subjects who could especially benefit from increases in physical activity but who rarely are recruited through more traditional approaches.

    T2 relaxometry, quantitative assessment of T2 relaxation time in magnetic resonance (MR) data, typically uses manually drawn regions of interest (ROIs). This approach is limited by its subjectivity and its restricted scope of investigation. A recently developed approach called voxel-based relaxometry (VBR) provides an unbiased statistical analysis of the whole brain. Our objective was to assess the clinical utility of single-subject VBR for patients with temporal lobe epilepsy (TLE). Forty-five patients with TLE confirmed by history, EEG, and structural MRI and 25 control subjects were scanned at 3T using a modified Carr-Purcell-Meiboom-Gill MR sequence. ROIs were drawn for each patient and control subject, and measurements were made on unregistered T2 maps. VBR was performed on a single-subject basis at a significance level of alpha=0.05. Patients were grouped according to seizure focus (left mesial, right mesial, other), and whether structural MR imaging was normal or abnormal. Up to 85% of patients in the temporal lobe groups demonstrated T2 abnormalities. VBR detected abnormalities either in equal numbers or in more patients (up to 23% more) than ROI analysis for each group. The number of detected abnormalities per patient was higher using VBR (3.38 versus 2.04, p<0.05). VBR also identified abnormalities that were missed by ROI analysis. The rate of VBR detection of abnormalities was higher for patients than controls (76% versus 36%). VBR can be performed on single subjects with TLE and it detects considerably more abnormalities than ROI analysis. VBR may be a clinically useful tool for the detection of T2 abnormalities at the seizure focus and sites remote from it.

    Although respiratory exacerbations are common in patients with quadriplegic cerebral palsy (CP), little is known about the factors that are related to increased exacerbation risk. This study aimed to identify the clinical and pulmonary function variables signaling risk of exacerbation in this type of patient. Thirty-one children and young adults with quadriplegic CP underwent a comprehensive history, physical examination, and pulmonary function test, including arterial blood gas analysis, airway resistance using the interrupter technique, and home overnight SpO2 monitoring. Subjects were divided into 2 groups depending on the number of respiratory exacerbations reported during the year before study entry: frequent exacerbators (ie, ≥ 2 exacerbations) and infrequent exacerbators (ie, < 2 exacerbations). The frequent exacerbators were more likely to require hospitalization due to respiratory disorders compared with the infrequent exacerbators (13/14 vs 9/17, P = .02). Respiratory exacerbation was found to be associated with diagnosis of gastroesophageal reflux (adjusted odds ratio of 23.95 for subjects with confirmed diagnosis, P = .02) and higher PaCO2 levels (adjusted odds ratio of 12.60 for every 5-mm Hg increase in PaCO2 , P = .05). Subjects with PaCO2 ≥ 35 mm Hg showed an exacerbation odds ratio of 15.2 (95% CI 1.5-152.5, P = .01). Gastroesophageal reflux and increased PaCO2 can be considered simple, clinically useful markers of increased exacerbation risk in young subjects with quadriplegic CP.

    Full Text Available Personality disorders are common in subjects with panic disorder. Personality disorders have shown to affect the course of panic disorder. The purpose of this study was to examine which personality disorders effect clinical severity in subjects with panic disorder. This study included 122 adults (71 female, 41 male, who met DSM-IV criteria for panic disorder (with or without agoraphobia. Clinical assessment was conducted by using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I, the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II and the Panic and Agoraphobia Scale (PAS, Global Assessment Functioning Scale (GAF, Beck Depression Inventory (BDI, and State-Trait Anxiety Inventory (STAI. Patients who had a history of sexual abuse were assessed with Sexual Abuse Severity Scale. Logistic regressions were used to identify predictors of suicide attempts, suicidal ideation, agoraphobia, different panic attack symptoms, sexual abuse, and early onset of disorders. The rates of comorbid Axis I and Axis II psychiatric disorders were 80.3% and 33.9%, consecutively, in patients with panic disorder. Panic disorder patients with comorbid personality disorders had more severe anxiety, depression and agoraphobia symptoms, and had earlier ages of onset, and lower levels of functioning. The rates of suicidal ideation and suicide attempts were 34.8% and 9.8%, consecutively, in subjects with panic disorder. The rate of patients with panic disorder had a history of childhood sexual abuse was 12.5%. The predictor of sexual abuse was more than one comorbid Axis II diagnosis. The predictors of suicide attempt were comorbid paranoid and borderline personality disorders, and the predictor of suicidal ideation was major depressive disorder in subjects with panic disorder. In conclusion, this study documents that comorbid personality disorders increase the clinical severity of panic disorder. Patients with more than one

    Full Text Available Introduction: The most frequent complication of A (H1N1 influenza and the leading cause of death was pneumonia with a primary viral or mixed viral and bacterial etiology. 182 patients had died because of a pandemic influenza in Poland by 31st July 2010.Material and Methods: A retrospective study of 6 fatal cases of pandemic influenza, aged 23-41, including 3 women, hospitalised between November 2009 and February 2011 in different Polish medical centres.Results: We present the clinical course of 6 late diagnosed cases of A (H1N1 influenza. All patients presented typical flu-like symptoms in the beginning. 4/6 patients had severe disease risk factors: pregnancy, arthritis, Wegener granulomatosis and obesity. All patients were seen by doctors, no one had received antiviral therapy, 4/5 were treated with antibiotics before they were hospitalized. One patient had nosocomial infection. Patients were admitted to the hospital on the 3rd to 8th day of the disease. They received oseltamivir treatment on the 4th to 9th day. All patients developed pneumonia complicated by acute respiratory distress syndrome. Death appeared between the 4th and 27th day after the onset of symptoms. Autopsies were performed in 5 cases and revealed haemorrhagic pneumonia in 2 patients.Conclusion: Delayed diagnosis and antiviral treatment initiation has a significant impact on mortality in A (H1N1 influenza. During the influenza epidemic, patients presenting typical symptoms should always be suspected of having influenza. Antiviral treatment has to be initiated immediately, especially ifthere are risk factors of severe disease.

    Full Text Available OBJECTIVE: The purpose of this study was to evaluate the accuracy of Spot Vision ScreeningTM as an autorefractor by comparing refraction measurements to subjective clinical refractometry results in children and adult patients. METHODS: One-hundred and thirty-four eyes of 134 patients were submitted to refractometry by Spot and clinical refractometry under cycloplegia. Patients, students, physicians, staff and children of staff from the Hospital das Clínicas (School of Medicine, University of São Paulo aged 7-50 years without signs of ocular disease were examined. Only right-eye refraction data were analyzed. The findings were converted in magnitude vectors for analysis. RESULTS: The difference between Spot Vision ScreeningTM and subjective clinical refractometry expressed in spherical equivalents was +0.66±0.56 diopters (D, +0.16±0.27 D for the vector projected on the 90 axis and +0.02±0.15 D for the oblique vector. CONCLUSIONS: Despite the statistical significance of the difference between the two methods, we consider the difference non-relevant in a clinical setting, supporting the use of Spot Vision ScreeningTM as an ancillary method for estimating refraction.

The difference between Spot Vision Screening™ and subjective clinical refractometry expressed in spherical equivalents was +0.66±0.56 diopters (D), +0.16±0.27 D for the vector projected on the 90 axis and +0.02±0.15 D for the oblique vector. Despite the statistical significance of the difference between the two methods, we consider the difference non-relevant in a clinical setting, supporting the use of Spot Vision Screening™ as an ancillary method for estimating refraction.

    OBJECTIVE: The purpose of this study was to evaluate the accuracy of Spot Vision ScreeningTM as an autorefractor by comparing refraction measurements to subjective clinical refractometry results in children and adult patients. METHODS: One-hundred and thirty-four eyes of 134 patients were submitted to refractometry by Spot and clinical refractometry under cycloplegia. Patients, students, physicians, staff and children of staff from the Hospital das Clínicas (School of Medicine, University of São Paulo) aged 7-50 years without signs of ocular disease were examined. Only right-eye refraction data were analyzed. The findings were converted in magnitude vectors for analysis. RESULTS: The difference between Spot Vision ScreeningTM and subjective clinical refractometry expressed in spherical equivalents was +0.66±0.56 diopters (D), +0.16±0.27 D for the vector projected on the 90 axis and +0.02±0.15 D for the oblique vector. CONCLUSIONS: Despite the statistical significance of the difference between the two methods, we consider the difference non-relevant in a clinical setting, supporting the use of Spot Vision ScreeningTM as an ancillary method for estimating refraction.

    Asthma seems to present in the elderly as a specific phenotype that remains to be further described. In this prospective observational study, we aimed to assess the multidimensional aspects of asthma in the elderly. In young (18 to 35 years old) subjects with mild to moderate asthma and elderly subjects (aged ≥60 years) either with or without mild to moderate asthma, we compared asthma control, health care and medication use, lung function, markers of airway and systemic inflammation, and adherence to therapy. Fifty subjects were recruited in each group. Elderly people with asthma showed more marked airway obstruction compared with young people with asthma and elderly people without asthma. They also had poorer asthma control, mainly associated with a lower FEV1, compared with young people with asthma, although airway responsiveness, health care use, prescribed doses of inhaled corticosteroids, and adherence to treatment were similar in both groups. Elderly subjects had an increase in some markers of systemic inflammation and bronchial epithelial dysfunction compared with young people with asthma. Blood eosinophils were higher in both asthma groups, particularly in elderly people with asthma. Sputum neutrophils were increased in both groups of elderly subjects and sputum eosinophils were increased in elderly people with asthma compared with the other two groups. Asthma in the elderly presents as a specific phenotype associated with increased airway obstruction and mixed airway inflammation in addition to signs of systemic inflammation.

    Full Text Available Recently the attention for mirror exercises in therapies targeted specifically to body experience concerns has increased. This retrospective study will explore the mirror behaviour of anorexia nervosa (AN, bulimia nervosa (BN and non-clinical female subjects (CG and investigate whether mirror avoidance or checking are related to negative body experiences.The group of eating disorders consisted of 560 AN and 314 BN patients. The control group consisted of 1151 female subjects. The Body Attitude Test and the Eating Disorder Inventory subscales drive for thinness and body dissatisfaction were used. To explore the mirror behaviour, one item of the Body Attitude Test ‘I am observing my appearance in the mirror’ was used. Nonparametric analyses (Spearman rho correlations, Kruskal-Wallis and Mann Whitney test were used because of the categorical data.BN patients observed their body more often in the mirror than AN patients and the control subjects do. Age and BMI showed no significant main effect of mirror frequency. The relation between the frequency of mirror behaviour and body experience were significant but low (under .40. AN patients and control subjects with a mirror checking behaviour had a more negative body experience than those with mirror avoidance behaviour. In the BN group, no differences were found.There is support to integrate mirror exercises in a treatment of eating disorder patients. From a clinical point, mirror exercises are preferably combined with a body oriented therapy within a multidimensional cognitive behavioural approach. Recommendations for mirror exercises based on the clinical experience are given.

    Full Text Available INTRODUCTION: In spite of the benefits of autopsies, there has been in recent years a drastic decline in the number of autopsies performed, mainly due to an apparent unattractive cost-benefit ratio and fears of the medico-legal consequences. MATERIAL AND METHODS: A retrospective study was conducted on the reports of all the 879 consecutive autopsies performed at "Policlinico of Bari" from 1990 to 2009. RESULTS: All clinical diagnoses were compared with autopsy findings showing 558 concordant diagnoses (most of all neoplasms; 123 certain discordant diagnoses (69 of them with potential impact on survival, such as acute myocardial infarctions, pulmonary thromboembolisms, internal haemorrhages, surgery complications, aortic aneurism ruptures, and so on; 116 uncertain discrepant diagnoses; 82 unclear diagnoses. CONCLUSIONS: The rate of discrepancy allows the authors to hypothesize that a better diagnostic assessment could lead to a different outcome. In terms of risk-management this negative performance needs to be carefully analysed and requires a comprehensive audit of all services provided. In this sense, the authors underline the crucial importance of autopsy as an essential tool to address unresolved clinical questions and highlight previously undiagnosed medical conditions.

    Background/Aim We present a clinical-neuroimaging study in a series of patients with a clinical diagnosis of semantic variant of primary progressive aphasia (svPPA), with the aim to provide clinical-functional correlations of the cognitive and behavioral manifestations at the single-subject level. Methods We performed neuropsychological investigations, 18F-FDG-PET single-subject and group analysis, with an optimized SPM voxel-based approach, and correlation analyses. A measurement of white matter integrity by means of diffusion tensor imaging (DTI) was also available for a subgroup of patients. Results Cognitive assessment confirmed the presence of typical semantic memory deficits in all patients, with a relative sparing of executive, attentional, visuo-constructional, and episodic memory domains. 18F-FDG-PET showed a consistent pattern of cerebral hypometabolism across all patients, which correlated with performance in semantic memory tasks. In addition, a majority of patients also presented with behavioral disturbances associated with metabolic dysfunction in limbic structures. In a subgroup of cases the DTI analysis showed FA abnormalities in the inferior longitudinal and uncinate fasciculi. Discussion Each svPPA individual had functional derangement involving an extended, connected system within the left temporal lobe, a crucial part of the verbal semantic network, as well as an involvement of limbic structures. The latter was associated with behavioral manifestations and extended beyond the area of atrophy shown by CT scan. Conclusion Single-subject 18F-FDG-PET analysis can account for both cognitive and behavioral alterations in svPPA. This provides useful support to the clinical diagnosis. PMID:25756991

    Full Text Available Brain changes reminiscent of Alzheimer disease (AD have been previously reported in a substantial portion of elderly cognitive healthy (HC subjects. The major aim was to evaluate the accuracy of MRI assessed regional gray matter (GM volume, 18F-fluorodeoxyglucose positron emission tomography (FDG-PET, and neuropsychological test scores to identify those HC subjects who subsequently convert to mild cognitive impairment (MCI or AD dementia. We obtained in 54 healthy control (HC subjects a priori defined region of interest (ROI values of medial temporal and parietal FDG-PET and medial temporal GM volume. In logistic regression analyses, these ROI values were tested together with neuropsychological test scores (free recall, trail making test B (TMT-B as predictors of HC conversion during a clinical follow-up between 3 and 4 years. In voxel-based analyses, FDG-PET and MRI GM maps were compared between HC converters and HC non-converters. Out of the 54 HC subjects, 11 subjects converted to MCI or AD dementia. Lower FDG-PET ROI values were associated with higher likelihood of conversion (p = 0.004, with the area under the curve (AUC yielding 82.0% (95% CI = (95.5%, 68.5%. The GM volume ROI was not a significant predictor (p = 0.07. TMT-B but not the free recall tests were a significant predictor (AUC = 71% (95% CI = 50.4%, 91.7%. For the combination of FDG-PET and TMT-B, the AUC was 93.4% (sensitivity = 82%, specificity = 93%. Voxel-based group comparison showed reduced FDG-PET metabolism within the temporo-parietal and prefrontal cortex in HC converters. In conclusion, medial temporal and-parietal FDG-PET and executive function show a clinically acceptable accuracy for predicting clinical progression in elderly HC subjects.

    Full Text Available Abstract Background Clinical (normative and subjective (self-assessment evaluation of caries and periodontal diseases have been reported to demonstrate a significant disparity. The dental public health team is obligated to recognize and understand this gap. The objectives of the study were to investigate the practical values of using questionnaires (self–perceived assessment as compared to clinical examinations (normative assessment and to evaluate the implications of the results in understanding the public's perception of oral health. Methods The investigation was performed on 4920, 21 year-old Israeli adults upon release from compulsory military service between 1996 and 1998. Participants were asked to fill in a questionnaire inquiring how they would rate their personal dental and periodontal health levels. Clinical examinations, employing the DMFT and CPITN indices, were performed to determine normative oral health status. Perceived and normative assessments were compared for sensitivity, specificity, positive and negative predictive values and overall proportions using the clinical examinations as a gold standard. Results The sensitivity (disease perception for dental status was found to be 0.34, while the specificity (health perception was found to be 0.83. The positive predictive value for perceived dental status was found to be 0.68, whereas the negative predictive value was found to be 0.54. The sensitivity for perceived periodontal status was found to be 0.28, while the specificity was found to be 0.83. The positive predictive value for perceived periodontal status was found to be 0.05, whereas the negative predictive value was found to be 0.97. Regarding the overall proportions, a large discrepancy was found between self–assessment and professional assessment for both dental and periodontal health status. Conclusions Self-assessment questionnaires were of low value in evaluating oral health status both in the individual and public

    Full Text Available BackgroundThe aims of this study are to investigate the glycemic efficacy and predictive parameters of vildagliptin therapy in Korean subjects with type 2 diabetes.MethodsIn this retrospective study, we retrieved data for subjects who were on twice-daily 50 mg vildagliptin for at least 6 months, and classified the subjects into five treatment groups. In three of the groups, we added vildagliptin to their existing medication regimen; in the other two groups, we replaced one of their existing medications with vildagliptin. We then analyzed the changes in glucose parameters and clinical characteristics.ResultsUltimately, 327 subjects were analyzed in this study. Vildagliptin significantly improved hemoglobin A1c (HbA1c levels over 6 months. The changes in HbA1c levels (ΔHbA1c at month 6 were -2.24% (P=0.000, -0.77% (P=0.000, -0.80% (P=0.001, -0.61% (P=0.000, and -0.34% (P=0.025 for groups 1, 2, 3, 4, and 5, respectively, with significance. We also found significant decrements in fasting plasma glucose levels in groups 1, 2, 3, and 4 (P<0.05. Of the variables, initial HbA1c levels (P=0.032 and history of sulfonylurea use (P=0.026 were independently associated with responsiveness to vildagliptin treatment.ConclusionVildagliptin was effective when it was used in subjects with poor glycemic control. It controlled fasting plasma glucose levels as well as sulfonylurea treatment in Korean type 2 diabetic subjects.

    Full Text Available Objective: This study was designed to compare the pattern of obstructive sleep apnea (OSA among obese and nonobese subjects regarding clinical and polysomnographic data obtained for a polysomnographic study. Methods: A cross-sectional retrospective descriptive study was conducted by analyzing polysomnographic data in 112 consecutive patients underwent a sleep study at our sleep laboratory from January 2009 to July 2010. Out of them, 81 were diagnosed to have OSA (apnea-hypopnoea Index ≥5. These patients were classified in two groups with body mass index (BMI 0.001. The minimal oxygen saturation was lower in the obese than the nonobese group (68.5 ± 13.00 vs. 80.3 ± 7.40, P0.001 and was well below 90% in both groups. Overall, the OSA in nonobese patients was mild-to-moderate as compared to that of the obese and no significant differences were observed between them as regard to age, gender, mean neck circumference, excessive daytime sleepiness, adenoid or tonsillar enlargement, smoking, and remaining polysomnographic parameters. Conclusion: Obstructive sleep apnea can occur in nonobese persons though with less severity as compared to obese leading to a concept that OSA is not restricted to obese persons only and there is a high demand of its awareness regarding evaluation, diagnosis, and management in such individuals.

    Antioxidants play a very crucial role in terms of disease incidence and its complications. Type 2 diabetes and metabolic syndrome (MetS) are now more prevalent than any other disorder. In this regard this study focuses on type 2 diabetic subjects with MetS having highest incidence of cardiovascular disease. Hence the aim of the study was to reveal the level of antioxidants and lipid peroxidation in MetS and non-MetS groups of type 2 diabetic subjects characterized by three different criteria. Present study was based on 70 type 2 diabetic subjects and 20 healthy controls. The metabolic syndrome criteria were defined by National Cholesterol Education Program (NCEP)-Adult Treatment Panel III (ATPIII), International Diabetes Federation (IDF), and World Health Organization (WHO). The selected subjects were of similar age group. The participants were selected from a diabetic camp being run in the University Campus. The antioxidant enzymes estimated were reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD) while Thiobarbituric acid reactive substances (TBARS) measured as a marker of lipid peroxidation. The level of GSH, CAT, SOD decreases in non-MetS and MetS subjects as compared to normal. When comparison was made for GSH & SOD in the mentioned groups resulted a significant differences in non-MetS and MetS compared with normal subjects. TBARS levels was increased in non-MetS and MetS group of subjects. The results indicate reduction in antioxidant enzymes and elevation of lipid peroxidation in type 2 diabetic subjects with or without MetS defined by using any of the International criteria. The study revealed that absolute reduction of antioxidant and involvement of lipid peroxidation in MetS group may lead to progressive intensification of cardiovascular disease in type 2 diabetic subjects irrespective of using any criteria.

  19. Cultural-psychological and clinical perspectives of research on phenomena of subjective uncertainty and ambiguity

    Directory of Open Access Journals (Sweden)

    Sokolova, Elena T.

    2013-06-01

    Full Text Available The article analyzes certain socio-cultural and personal predispositions, which determine the modern diversity of subjective uncertainty and ambiguity manifestations. It stresses that for the creation of ‘realistic’ clinical psychology (in terms of A.R. Luria one needs to retrace the relations between the resourceful and the psychopathological aspects of the ambiguity phenomenon and the cultural environment with its destructive ideals and mythologems, manipulative media-technologies and all-pervading idea of ‘deconstruction’. Methods for modeling the experiences of ambiguity in experimental settings, in pathopsychological examination and in projective psychological diagnostics are put in comparison. The arguments are adduced for the interpretation of deficient manifestations of subjective uncertainty as a criterion for diagnostics of the severity of personality disorder.

    PurposeTo define the genetic spectrum and relative gene frequencies underlying clinical frontotemporal dementia (FTD).MethodsWe investigated the frequencies and mutations in neurodegenerative disease genes in 121 consecutive FTD subjects using an unbiased, combined sequencing approach, complemented by cerebrospinal fluid Aβ1-42 and serum progranulin measurements. Subjects were screened for C9orf72 repeat expansions, GRN and MAPT mutations, and, if negative, mutations in other neurodegenerative disease genes, by whole-exome sequencing (WES) (n = 108), including WES-based copy-number variant (CNV) analysis.ResultsPathogenic and likely pathogenic mutations were identified in 19% of the subjects, including mutations in C9orf72 (n = 8), GRN (n = 7, one 11-exon macro-deletion) and, more rarely, CHCHD10, TARDBP, SQSTM1 and UBQLN2 (each n = 1), but not in MAPT or TBK1. WES also unraveled pathogenic mutations in genes not commonly linked to FTD, including mutations in Alzheimer (PSEN1, PSEN2), lysosomal (CTSF, 7-exon macro-deletion) and cholesterol homeostasis pathways (CYP27A1).ConclusionOur unbiased approach reveals a wide genetic spectrum underlying clinical FTD, including 11% of seemingly sporadic FTD. It unravels several mutations and CNVs in genes and pathways hitherto not linked to FTD. This suggests that clinical FTD might be the converging downstream result of a delicate susceptibility of frontotemporal brain networks to insults in various pathways.Genetics in Medicine advance online publication, 27 July 2017; doi:10.1038/gim.2017.102.

    Full Text Available The main objective of the present study was to evaluate the diagnostic value (clinical application of brain measures and cognitive function. Alzheimer and multiinfarct patients (N = 30 and normal subjects over the age of 50 (N = 40 were submitted to a medical, neurological and cognitive investigation. The cognitive tests applied were Mini-Mental, word span, digit span, logical memory, spatial recognition span, Boston naming test, praxis, and calculation tests. The brain ratios calculated were the ventricle-brain, bifrontal, bicaudate, third ventricle, and suprasellar cistern measures. These data were obtained from a brain computer tomography scan, and the cutoff values from receiver operating characteristic curves. We analyzed the diagnostic parameters provided by these ratios and compared them to those obtained by cognitive evaluation. The sensitivity and specificity of cognitive tests were higher than brain measures, although dementia patients presented higher ratios, showing poorer cognitive performances than normal individuals. Normal controls over the age of 70 presented higher measures than younger groups, but similar cognitive performance. We found diffuse losses of tissue from the central nervous system related to distribution of cerebrospinal fluid in dementia patients. The likelihood of case identification by functional impairment was higher than when changes of the structure of the central nervous system were used. Cognitive evaluation still seems to be the best method to screen individuals from the community, especially for developing countries, where the cost of brain imaging precludes its use for screening and initial assessment of dementia.

    There is increasing literature suggesting a link between attention-deficit hyperactivity disorder (ADHD) and eating disorders (EDs), especially bulimia nervosa. ADHD is under-diagnosed in girls and children of high intelligence are typically missed. We identified a case of a 23-year-old woman suffering from severe bulimia nervosa and previously unsuspected ADHD in adulthood; we diagnosed and treated her with extended-release methylphenidate. We performed a literature review on the ADHD and bulimia nervosa comorbidity. We discuss the reasons why her ADHD remained undiagnosed and the difficulties in diagnosing ADHD in patients with EDs. We suggest that identifying comorbid ADHD is crucial for these patients and argue for the use of a structured interview, collateral history and investigation of onset of symptoms to establish a diagnosis of ADHD in adults with bulimia nervosa. Comorbidities and overlap of symptomatology need to be taken into account. Copyright © 2013 Wiley Periodicals, Inc.

    Full Text Available The important task of nevrology is to improve the diagnosis of chronic progressive degenerative and vascular brain diseases – to detect them at the earliest stages. The paper presents current views on the non-dementia stages of brain diseases: moderate, mild, and subjective cognitive impairments. It sets forth data on their prevalence and clinical features and types, as well as international diagnostic criteria. There is evidence for the expediency of the earliest neuroprotective therapy to prevent dementia. A methodology for neuroprotective therapy is discussed; the available data on the long-term effect of intermittent treatment cycles with the vasotropic and neurometabolic drug tanakan are given.

  4. The pharmaceutical industry's responsibility for protecting human subjects of clinical trials in developing nations.

    Pharmaceutical companies increasingly perform clinical trials in developing nations. Governments of host nations see the trials as a way to provide otherwise unaffordable medical care, while trial sponsors are drawn to those countries by lower costs, the prevalence of diseases rare in developed nations, and large numbers of impoverished patients. Local governments, however, fail to police trials, and the FDA does not monitor trials in foreign countries, resulting in the routine violation of international standards for the protection of human subjects. This Note proposes independent accreditation of those institutions involved in clinical trials--the institutional review boards which oversee trial protocol; the organizations, such as pharmaceutical companies, which sponsor the trials; and the research organizations that conduct the trials. Accreditation, similar to that used in the footwear and apparel industries, would increase the transparency of pharmaceutical trials and would enable the United States government and consumers to hold trial sponsors accountable for their actions.

    Full Text Available Objective: Skin prick test (SPT is used widely to determine the allergens in atopic patients. In this study, we aimed to determine the spectrum of aeroallergen sensitivity of atopic asthmatic subjects in Şanlıurfa district. Methods: We evaluated clinical, demographic findings and SPT results of 95 male and 162 female in a total 257 patients who had asthma and allergic symptoms. Results: Most common allergens causing a sensitivity reaction detected in our clinic were as follows; cockroach (56.8%, wheat pollen (53.3%, corn pollen (47.4%, grass pollen (36.5%, poplar tree pollen (26%, house dust mite (19.4%, pepper (16.7% and cat dander (15.1%. Conclusion: High levels of sensitivity to wheat and corn pollens and relatively low sensitivity levels of cat dander results meet our expectations in the area of agricultural land and where pet ownership is not common.

    Although recommended, both the Cockcroft and Gault formula (CG) and the modification of diet in renal disease (MDRD) equation are not ideally predictive of glomerular filtration rate (GFR) in diabetic subjects; we tested whether the new Mayo Clinic Quadratic (MCQ) equation performed better. In 200 diabetic subjects with a wide range of renal function, GFR was measured by 51Cr-EDTA clearance, and compared with the results of the three predictive equations by regression analysis and Bland and Altman procedures. The correlations with body mass index, age and albumin excretion rates were tested. The precisions (absolute difference as percentage), diagnostic accuracies [receiver operating characteristic (ROC) curves for the diagnosis of moderate and severe chronic kidney disease (CKD)], and the results of stratification according to the KDOQ classification were compared. The CG and MCQ overestimated mean GFR, whereas the MDRD underestimated it. Correlation coefficients and areas under the ROC curves were better for the MDRD and the MCQ as compared with the CG, which was biased by body weight (+30% overestimation in obese diabetic subjects). The absolute differences with true GFR were slightly lower for the MDRD than the MCQ, and both better than the CG. Both the MDRD and MCQ correctly stratified 65% of the subjects (CG: 55%, P<0.05). In contrast with the MDRD, the MCQ did not underestimate normal GFR, and its performance for stratification was uniformly good over a wide GFR range. In diabetic subjects, the MCQ has a similar diagnostic performance to the MDRD, but it does not underestimate normal GFR, which is an important advantage.

    Arterial blood gas (ABG) analysis is not a routine test in sleep laboratories due to its invasive nature. Therefore, the diagnosis of obesity hypoventilation syndrome (OHS) is underestimated. We aimed to evaluate the differences in subjects with OHS and pure obstructive sleep apnea (OSA) and to determine clinical predictors of OHS in obese subjects. Demographics, body mass index (BMI), Epworth Sleepiness Scale score, polysomnographic data, ABG, spirometric measurements, and serum bicarbonate levels were recorded. Of 152 obese subjects with OSA (79 females/73 males, mean age of 50.3 ± 10.6 y, BMI of 40.1 ± 5.6 kg/m(2), 51.9% with severe OSA), 42.1% (n = 64) had OHS. Subjects with OHS had higher BMI (P = .02), neck circumference (P sleep time with S(pO2) sleep efficiency (P = .032), mean S(pO2) (P < .001), and nadir S(pO2) (P < .001). Serum bicarbonate levels and nadir S(pO2) were the only independent predictive factors for OHS. A serum bicarbonate level of ≥ 27 mmol/L as the cutoff gives a satisfactory discrimination for the diagnosis of OHS (sensitivity of 76.6%, specificity of 74.6%, positive predictive value of 54.5%, negative predictive value of 88.9%). A nadir S(pO2) of < 80% as the cutoff gives a satisfactory discrimination for the diagnosis of OHS (sensitivity of 82.8%, specificity of 54.5%, positive predictive value of 56.9%, negative predictive value of 81.4%). When we used a serum bicarbonate level of ≥ 27 mmol/L and/or a nadir S(pO2) of < 80% as a screening measure, only 3 of 64 subjects with OHS were missed. Serum bicarbonate level and nadir saturation were independent predictive factors for the diagnosis of OHS. Copyright © 2015 by Daedalus Enterprises.

Patients with newly diagnosed T2DM (n = 624) were enrolled and divided into different groups according to levels of serum TG. All patients underwent oral glucose tolerance tests and insulin releasing tests. Demographic data, lipid profiles, glucose levels, and insulin profiles were compared between different groups. Basic insulin secretion function index (homeostasis model assessment for beta cell function index, HOMA-β), modified beta cell function index (MBCI), glucose disposition indices (DI), and early insulin secretion function index (insulinogenic index, IGI) were used to evaluate the beta cell function. Patients of newly diagnosed T2DM with hypertriglyceridemia were younger, fatter and had worse lipid profiles, glucose profiles, and high insulin levels than those with normal TG. There is no difference in early phase insulin secretion among groups of newly diagnosed T2DM patients with different TG levels. The basal beta cell function (HOMA-β and MBCI) initially increased along rising TG levels and then decreased as the TG levels rose further. The insulin sensitivity was relatively high in patients with a low level of TG and low with a high level of TG. Hypertriglyceridemia influences clinical characteristics and β cell function of Chinese patients with newly diagnosed T2DM. A better management of dyslipidemia may, to some extent, reduce the effect of lipotoxicity, thereby improving glucose homeostasis in patients with newly diagnosed T2DM.

    Studies have assessed the outcome of hallux valgus surgeries based on subjective questionnaires, usually the American Orthopaedic Foot and Ankle Society Score, and radiographic results reporting good to excellent outcome at 6-12 months postoperatively. However, contrasting results were reported by gait studies at 12-24 months postoperatively. In a previous study, we found nine gait parameters which can describe the altered gait in hallux valgus deformity. This study aimed, to assess the outcome of modified Lapidus at 6 months postoperatively, using gait assessment method, to determine if the nine specified gait parameters effectively relates with the clinical scores and the radiological results or add information missed by these commonly used clinical assessments. We assessed 21 participants including 11 controls and 10 patients with moderate to severe hallux valgus deformity. The patient group was followed 6 months postoperatively. The ambulatory gait assessment was performed utilizing pressure insoles and inertial sensors. Clinical assessment includes foot and ankle questionnaires along with radiographic results. Comparison was made using non parametric tests, Phallux valgus surgeries. The existing clinical assessment overestimates the functional outcome at the early postoperative phase.

    Conclusion: Once AFDLAJ appears in neutral position and rotational fixation or asymmetry in rotary position, atlantoaxial subluxation can be ascertained, as well as the type and extent of subluxation, and fake subluxation due to the head's rotation or normal lateralized odontoid can be excluded. AFDLAJ is a vital direct sign in diagnosing atlantoaxial subluxation.

    Informed consent is a critical issue especially in conducting clinical trials that expose human life to medical or surgical interventions. It necessitates a long and complex process through which the participant is presented with all potential favorable and non-favorable consequences upon getting enrolled in the study. The process of taking informed consent is well-understood in developed countries, with every effort taken to enhance and maintain the autonomy of patients and their right to make an informed choice of whether to participate or not. This may not be the case in the developing world.The information given to patients before the trial might not be properly developed and presented, an issue that can result in serious threat to the decision-making process. On the other hand, investigators should remember that enrolling people into a trial with no potential benefit for themselves cannot be considered ethical. In the current debate, we aim to address the issue of how respectfully and ethically clinical research trials can be done on human subjects and what we can do to enhance the practice in an ethical context. Development of a system through which we could warrant all rights of study participants in all cases around the world seems far from view. However, if we are in doubt about the ethics of a clinical trial, we can ask ourselves: "what would we do, if we were in the same position our patients are in now?"

    The craniovertebral junction is anatomically complicated. Representative vertebral artery (VA) variations include the persistent first intersegmental artery (FIA), fenestration of the VA above and below C1 (FEN), posterior inferior cerebellar artery (PICA) from C1/2, and high-riding VA (HRVA). The ponticulus posticus (PP) is a well-known osseous anomaly at C1. Although those anomalies are frequent in patients with cervical deformity, the prevalence of these in subjects with normal cervical spines is still unknown. The aim of this study is to investigate the variations and prevalence of vascular and osseous anomalies based on three-dimensional computed tomographic (3D CT) angiography in patients without any cervical diseases, such as rheumatoid arthritis, Klippel-Feil syndrome, or Down syndrome. Eligible subjects were patients who underwent 3D CT angiography by the Department of Otorhinolaryngology and Internal Medicine from January 2009 to October 2013 in our institution. The authors defined a HRVA as a C2 pedicle with a maximum diameter of 4 mm or less. Among 480 subjects with a mean age of 63.1 years, 387 patients were eligible. One hundred and eighteen subjects were female, and 269 were male. HRVA was observed in 10.1 % of patients (39 out of 387 cases), FIA in 1.8 % (7 cases), FEN in 1.3 % (5 cases), and PICA in 1.3 % (5 cases). PP was observed in 6.2 % of patients (24 cases). According to past reports, many VA anomalies could be attributed to congenital or acquired conditions (e.g., rheumatoid arthritis). However, VA anomalies appear to exist even in patients without any such cervical diseases. (orig.)

    To study the effect of BMI on the prevalence, severity, and 36-month progression of early degenerative changes in the knee by using 3T MRI in middle-aged subjects without radiographic osteoarthritis (OA). We examined baseline and 36-month follow-up MR studies from 137 middle-aged individuals (45-55 years old) with risk factors for knee OA but no radiographic OA from the Osteoarthritis Initiative. Subjects were grouped into three categories: normal BMI (BMI < 25 kg/m{sup 2}, n = 38), overweight (BMI 25-29.9 kg/m{sup 2}, n = 37), and obese (BMI {>=} 30 kg/m{sup 2}, n = 62). Using 3T MRI, cartilage, meniscus, and bone marrow abnormalities were graded using the OA Whole-organ MR Imaging Score (WORMS). The statistical analysis was corrected as necessary for differences in age, sex, and OA risk factors other than BMI. The overall prevalence of lesions was 64% for meniscus and 79% for cartilage (including low grade lesions). At baseline, the prevalence and severity of knee lesions was positively associated with BMI, with a nearly fourfold increase in meniscal tears and more than twofold increase in high-grade cartilage defects in obese individuals relative to normal-weight subjects. Over the 36-month follow-up period, the number of new or worsening cartilage lesions of any grade was significantly higher in obese subjects (p = 0.039), while there was no significant difference in meniscal lesion progression. Obesity was associated with both higher prevalence and severity of early degenerative changes in the knee in middle-aged individuals without radiographic OA and with significantly increased cartilage lesion progression (of any grade) over 36 months.

    Background The clinical features of atherosclerotic lesions in ketosis-onset diabetes are largely absent. We aimed to compare the characteristics of lower limb atherosclerotic lesions among type 1, ketosis-onset and non-ketotic type 2 diabetes. Methods A cross-sectional study was performed in newly diagnosed Chinese patients with diabetes, including 53 type 1 diabetics with positive islet-associated autoantibodies, 208 ketosis-onset diabetics without islet-associated autoantibodies, and 215 non-ketotic type 2 diabetics. Sixty-two subjects without diabetes were used as control. Femoral intima-media thickness (FIMT), lower limb atherosclerotic plaque and stenosis were evaluated and compared among the four groups based on ultrasonography. The risk factors associated with lower limb atherosclerotic plaque were evaluated via binary logistic regression in patients with diabetes. Results After adjusting for age and sex, the prevalence of lower limb plaque in the patients with ketosis-onset diabetes (47.6%) was significantly higher than in the control subjects (25.8%, p = 0.013), and showed a higher trend compared with the patients with type 1 diabetes (39.6%, p = 0.072), but no difference was observed in comparison to the patients with non-ketotic type 2 diabetes (62.3%, p = 0.859). The mean FIMT in the ketosis-onset diabetics (0.73 ± 0.17 mm) was markedly greater than that in the control subjects (0.69 ± 0.13 mm, p = 0.045) after controlling for age and sex, but no significant differences were found between the ketosis-onset diabetics and the type 1 diabetics (0.71 ± 0.16 mm, p = 0.373), and the non-ketotic type 2 diabetics (0.80 ± 0.22 mm, p = 0.280), respectively. Age and FIMT were independent risk factors for the presence of lower limb plaque in both the ketosis-onset and non-ketotic type 2 diabetic patients, while sex and age in the type 1 diabetic patients. Conclusions The prevalence and risk of lower limb

    Two versions of the International Knee Documentation Committee (IKDC) Subjective Knee Evaluation form currently exist: the original version (1999) and a recently modified pediatric-specific version (2011). Comparison of the pediatric IKDC with the adult version in the adult population may reveal that either version could be used longitudinally. We hypothesize that the scores for the adult IKDC and pediatric IKDC will not be clinically different among adult patients aged 18 to 50 years. Randomized crossover study design. Level 2. The study consisted of 100 participants, aged 18 to 50 years, who presented to orthopaedic outpatient clinics with knee problems. All participants completed both adult and pediatric versions of the IKDC in random order with a 10-minute break in between. We used a paired t test to test for a difference between the scores and a Welch's 2-sample t test to test for equivalence. A least-squares regression model was used to model adult scores as a function of pediatric scores, and vice versa. A paired t test revealed a statistically significant 1.6-point difference between the mean adult and pediatric scores. However, the 95% confidence interval (0.54-2.66) for this difference did not exceed our a priori threshold of 5 points, indicating that this difference was not clinically important. Equivalence testing with an equivalence region of 5 points further supported this finding. The adult and pediatric scores had a linear relationship and were highly correlated with an R2 of 92.6%. There is no clinically relevant difference between the scores of the adult and pediatric IKDC forms in adults, aged 18 to 50 years, with knee conditions. Either form, adult or pediatric, of the IKDC can be used in this population for longitudinal studies. If the pediatric version is administered in adolescence, it can be used for follow-up into adulthood.

  2. Facing death, gazing inward: end-of-life and the transformation of clinical subjectivity in Thailand.

    Science.gov (United States)

    Stonington, Scott

    2011-06-01

    In this article, I describe a new form of clinical subjectivity in Thailand, emerging out of public debate over medical care at the end of life. Following the controversial high-tech death of the famous Buddhist monk Buddhadasa, many began to denounce modern death as falling prey to social ills in Thai society, such as consumerism, technology-worship, and the desire to escape the realities of existence. As a result, governmental and non-governmental organizations have begun to focus on the end-of-life as a locus for transforming Thai society. Moving beyond the classic outward focus of the medical gaze, they have begun teaching clinicians and patients to gaze inward instead, to use the suffering inherent in medicine and illness to face the nature of existence and attain inner wisdom. In this article, I describe the emergence of this new gaze and its major conceptual components, including a novel idea of what it means to be 'human,' as well as a series of technologies used to craft this humanity: confession, "facing suffering," and untying "knots" in the heart. I also describe how this new subjectivity has begun to change the long-stable Buddhist concept of death as taking place at a moment in time, giving way for a new concept of "end-of-life," an elongated interval to be experienced, studied, and used for inner wisdom.

    Water drinking acutely increases sympathetic activity in human subjects. In animals, the response appears to be mediated through transient receptor potential channel TRPV4 activation on osmosensitive hepatic spinal afferents, described as osmopressor response. We hypothesized that hepatic denervation attenuates water drinking-induced sympathetic activation. We studied 20 liver transplant recipients (44±2.6 years, 1.2±0.1 years post transplant) as model of hepatic denervation and 20 kidney transplant recipients (43±2.6 years, 0.8±0.1 years post transplant) as immunosuppressive drug matched control group. Before and after 500 ml water ingestion, we obtained venous blood samples for catecholamine analysis. We also monitored brachial and finger blood pressure, ECG, and thoracic bioimpedance. Plasma norepinephrine concentration had changed by 0.01±0.07 nmol/l in liver and by 0.21±0.07 nmol/l in kidney transplant recipients (pwater drinking. While blood pressure and systemic vascular resistance increased in both groups, the responses tended to be attenuated in liver transplant recipients.

    Most primary severe hypertriglyceridemias (HTGs) are diagnosed in adults, but their molecular foundations have not been completely elucidated. We aimed to identify rare dysfunctional mutations in genes encoding regulators of lipoprotein lipase (LPL) function in patients with familial and non-familial primary HTG. We sequenced promoters, exons, and exon-intron boundaries of LPL, APOA5, LMF1, and GPIHBP1 in 118 patients with severe primary HTG (triglycerides >500 mg/dL) and 53 normolipidemic controls. Variant functionality was analyzed using predictive software and functional assays for mutations in regulatory regions. We identified 29 rare variants, 10 of which had not been previously described: c.(-16A>G), c.(1018+2G>A), and p.(His80Arg) in LPL; p.(Arg143Alafs*57) in APOA5; p.(Val140Ile), p.(Leu235Ile), p.(Lys520*), and p.(Leu552Arg) in LMF1; and c.(-83G>A) and c.(-192A>G) in GPIHBP1. The c.(1018+2G>A) variant led to deletion of exon 6 in LPL cDNA, whereas the c.(-16A>G) analysis showed differences in the affinity for nuclear proteins. Overall, 20 (17.0%) of the patients carried at least one allele with a rare pathogenic variant in LPL, APOA5, LMF1, or GPIHBP1. The presence of a rare pathogenic variant was not associated with lipid values, family history of HTG, clinical diagnosis, or previous pancreatitis. Less than one in five subjects with triglycerides >500 mg/dL and no major secondary cause for HTG may carry a rare pathogenic mutation in LPL, APOA5, LMF1, or GPIHBP1. The presence of a rare pathogenic variant is not associated with a differential phenotype. Copyright © 2016 National Lipid Association. Published by Elsevier Inc. All rights reserved.

    This is one of the first studies to (1) describe the out-of-hospital burden of influenza-like-illness (ILI) and clinically diagnosed flu, also for patients not seeking professional medical care, (2) assess influential background characteristics, and (3) formally compare the burden of ILI in patients with and without a clinical diagnosis of flu. A general population sample with recent ILI experience was recruited during the 2011-2012 influenza season in Belgium. Half of the 2250 respondents sought professional medical care, reported more symptoms (especially more often fever), a longer duration of illness, more use of medication (especially antibiotics) and a higher direct medical cost than patients not seeking medical care. The disease and economic burden were similar for ambulatory ILI patients, irrespective of whether they received a clinical diagnosis of flu. On average, they experienced 5-6 symptoms over a 6-day period; required 1.6 physician visits and 86-91% took medication. An average episode amounted to €51-€53 in direct medical costs, 4 days of absence from work or school and the loss of 0.005 quality-adjusted life-years. Underlying illness led to greater costs and lower quality-of-life. The costs of ILI patients with clinically diagnosed flu tended to increase, while those of ILI patients without clinically diagnosed flu tended to decrease with age. Recently vaccinated persons experienced lower costs and a higher quality-of-life, but this was only the case for patients not seeking professional medical care. This information can be used directly to evaluate the implementation of cost-effective prevention and control measures for influenza. In particular to inform the evaluation of more widespread seasonal influenza vaccination, including in children, which is currently considered by many countries.

    2005-01-01

    The prevalence of caries, and its preferential location, has changed in recent years. The percentage reduction in caries has been lower in pits and fissures than in other locations, making it necessary to use more sensitive diagnostic procedures than visual inspection for approximal lesions. The objective of this study was to compare the amount of overlooked proximal caries by bitewing X-rays versus clinical in patients who were completing a public oral health program at the age of 14 years. 162 children aged 14 years were clinically examined by a dentist as part of the systematic six-monthly dental check-ups of the children. The survey was carried out on dried teeth using a light, plane mouth mirror and blunt probe. All molar and premolar surfaces were examined in order to determine the presence of caries or restorations. In addition, two bitewing radiographs of each patient were obtained using a Klauser plastic parallelizer. Caries lesions were diagnosed better by the X-rays than clinically (delta X-ray = 0.61), whereas clinical examination was better at diagnosing the presence of fillings (delta X-ray = -0.03). Clinical examination diagnosed all occlusal caries but underestimated the interproximal lesions by 86.84%. In the context of public oral health programs, the authors consider it necessary to obtain two bitewing X-rays of the children's teeth before discharging them, as otherwise they could be told that they are healthy whereas, in fact, they present interproximal caries that could be treated by remineralization or restorative methods.

    The [123I]ioflupane - a dopamine transporter radioligand - SPECT (DaT-SPECT) has proven to be useful in the differential diagnosis of tremor. Here, we investigate the diagnoses behind patients with hard-to-classify tremor and normal DaT-SPECT. Therefore, 30 patients with tremor and normal DaT-SPECT were followed up for 2 years. In 18 cases we were able to make a diagnosis. The residual 12 patients underwent a second DaT-SPECT, were then followed for additional 12 months and thereafter the dia...

    One could be forgiven for thinking that the only road to evidence-based clinical practice is the application of results from randomised controlled trials (or systematic reviews of such). By contrast, single-subject designs in the context of evidence-based clinical practice are believed by many to be strange bedfellows. In this paper, we argue that single-subject designs play an important role in evidence-based clinical practice. We survey the contents of Neuropsychological Rehabilitation in relation to single-subject designs and tackle the main criticisms that have been levelled against them. We offer practical guidance for rating the methodological quality of single-subject designs and applying statistical techniques to measure treatment efficacy. These guides are equally applicable to research studies and everyday clinical practice with individual patients.

    Existing health literacy assessments developed for research purposes have constraints that limit their utility for clinical practice, including time requirements and administration protocols. The Brief Health Literacy Screen (BHLS) consists of 3 self-administered Single-Item Literacy Screener (SILS) questions and obviates these clinical barriers. We assessed whether the addition of SILS items or the BHLS to patient demographics readily available in ambulatory clinical settings reaching underserved patients improves the ability to identify limited health literacy. We analyzed data from 2 cross-sectional convenience samples of patients from an urban academic emergency department (n = 425) and a primary care clinic (n = 486) in St. Louis, Missouri. Across samples, health literacy was assessed using the Rapid Estimate of Adult Literacy in Medicine-Revised (REALM-R), Newest Vital Sign (NVS), and the BHLS. Our analytic sample consisted of 911 adult patients, who were primarily female (62%), black (66%), and had at least a high school education (82%); 456 were randomly assigned to the estimation sample and 455 to the validation sample. The analysis showed that the best REALM-R estimation model contained age, sex, education, race, and 1 SILS item (difficulty understanding written information). In validation analysis this model had a sensitivity of 62%, specificity of 81%, a positive likelihood ratio (LR(+)) of 3.26, and a negative likelihood ratio (LR(-)) of 0.47; there was a 28% misclassification rate. The best NVS estimation model contained the BHLS, age, sex, education and race; this model had a sensitivity of 77%, specificity of 72%, LR(+) of 2.75, LR(-) of 0.32, and a misclassification rate of 25%. Findings suggest that the BHLS and SILS items improve the ability to identify patients with limited health literacy compared with demographic predictors alone. However, despite being easier to administer in clinical settings, subjective estimates of health literacy have

    Full Text Available BACKGROUND Allergic rhinitis is known to be one of the most common chronic diseases in the world. In this study, we provide an overview of allergic rhinitis responding to immunostimulating agents. According to the concept that allergic rhinitis patients generally suffer from an immune deficit in order to stimulate their immune system specifically or nonspecifically, immunomodulating agents from various sources such as synthetic compounds, tissue extracts or a mixture of bacterial extracts have been used. MATERIALS AND METHODS The aim of the present trial is to evaluate the efficacy of the treatment with an immunostimulating agent consisting of a freeze dried bacterial lysates (Ismigen and analyse the improvement in clinical response in allergic rhinitis patients. 50 allergic rhinitis patients were enrolled. For all patients, after 3 months of PMBL (polyvalent mechanical bacterial lysates treatment clinical response was analysed. RESULTS A clinical improvement in subjective symptoms was observed in 43 of the 50 patients treated with bacterial lysates (85.6%. The results are as follows- 45 patients (91.8%, we noticed a decrease in symptoms of nasal blockage and 38 patients (90.4% were relieved from rhinorrhea; purulent nasal discharge was reduced in 13 cases (81.5%, 30 patients (90.9% had a large improvement in nasal/palate itching and 15 patients (75% with headache were relieved. CONCLUSION From this study, bacterial lysates have shown to have a protective effect, which induces a significant reduction of the symptoms and duration related to allergic rhinitis. No negative side effects or worsening of the symptoms have been observed with this medication.

    The association between restless legs syndrome (RLS) and obstructive sleep apnea syndrome (OSAS) has seldom been reported. There is one study reporting improvement of RLS symptoms severity in patients naive of treatment after initiation of continuous positive airway pressure (CPAP) for OSAS. The aim of this study was to evaluate the impact of the OSAS treatment in patients with previously diagnosed, clinically significant RLS in a usual clinical setting. This was a retrospective study of RLS patients from a sleep clinic with a concomitant or subsequent diagnosis of OSAS. All patients who started treatment for OSAS and had a follow-up of ≥3 months were selected. Exclusion criteria included noncompliance, absence of sufficient information on clinical records, and RLS improvement following treatment of secondary causes. The primary outcome variable was clinical status of RLS symptoms following OSA treatment. Other variables included demographics, RLS treatment and outcome, OSA diagnosis, treatment, compliance, outcome, and PSG characteristics. From a database of 97 RLS patients, 56 patients had both OSA and RLS. Of these patients, 28 met the criteria for the study. In all, 17 patients (60.9%) were female, with a mean age 60 years. A total of 16 patients (57.1%) were diagnosed with idiopathic RLS. OSAS was diagnosed, on average, 21 months after the RLS diagnosis. A total of 19 (70.4%) patients were overweight or obese, 26 (92.9%) reported snoring, and 10 (35.7%) witnessed apneas. A total of 16 patients (57.1%) had excessive daytime sleepiness and 23 (84.1%) had insomnia. The mean apnea-hypopnea index was 19. Patients were mostly treated with dopamine agonists (19 patients, 67.9%) for the RLS, and nine patients were treated with more than two drugs for RLS. A total of 20 patients (71.4%) had improvement of symptoms of RLS after therapy for OSAS, of whom nine stopped drug therapy and eight reduced the dose. In patients with clinically significant RLS, treatment of

    Background This study aimed to better understand the supporting role that mutational profiling (MP) of DNA from microdissected cytology slides and supernatant specimens may play in the diagnosis of malignancy in fine-needle aspirates (FNA) and biliary brushing specimens from patients with pancreaticobiliary masses. Methods Cytology results were examined in a total of 30 patients with associated surgical (10) or clinical (20) outcomes. MP of DNA from microdissected cytology slides and from discarded supernatant fluid was analyzed in 26 patients with atypical, negative or indeterminate cytology. Results Cytology correctly diagnosed aggressive disease in 4 patients. Cytological diagnoses for the remaining 26 were as follows: 16 negative (9 false negative), 9 atypical, 1 indeterminate. MP correctly determined aggressive disease in 1 false negative cytology case and confirmed a negative cytology diagnosis in 7 of 7 cases of non-aggressive disease. Of the 9 atypical cytology cases, MP correctly diagnosed 7 as positive and 1 as negative for aggressive disease. One specimen that was indeterminate by cytology was correctly diagnosed as non-aggressive by MP. When first line malignant (positive) cytology results were combined with positive second line MP results, 12/21 cases of aggressive disease were identified, compared to 4/21 cases identified by positive cytology alone. Conclusions When first line cytology results were uncertain (atypical), questionable (negative), or not possible (non-diagnostic/indeterminate), MP provided additional information regarding the presence of aggressive disease. When used in conjunction with first line cytology, MP increased detection of aggressive disease without compromising specificity in patients that were difficult to diagnose by cytology alone.

    Purpose To investigate the initial clinical value of fluorine 18 (18F) fluorocholine (FCH) dynamic positron emission tomography (PET)/magnetic resonance (MR) imaging by comparing its parameters with clinical-pathologic findings in patients with newly diagnosed intermediate- to high-risk prostate cancer (PCa) who plan to undergo radical prostatectomy. Materials and Methods The institutional review board approved the study protocol, and informed written consent was obtained from all subjects for this HIPAA-compliant study. Twelve men (mean age ± standard deviation, 61.7 years ± 8.4; range, 46-74 years) with untreated intermediate- to high-risk PCa characterized according to Cancer of the Prostate Risk Assessment (CAPRA) underwent preoperative FCH dynamic PET/MR imaging followed by radical prostatectomy between April and November 2015. PET/MR imaging parameters including average and maximum K1 (delivery rate constant) and standardized uptake values (SUVs) and Prostate Imaging Reporting and Data System (PI-RADS) version 2 scores were measured and compared with clinical-pathologic characteristics. For statistical analysis, the Spearman rank correlation and Mann-Whitney U tests were performed. Results Of the PET parameters, maximum SUV of primary tumors showed significant correlations with several clinical-pathologic parameters including serum prostate-specific antigen level (ρ = 0.71, P = .01), pathologic stage (ρ = 0.59, P = .043), and postsurgical CAPRA score (ρ = 0.72, P = .008). The overall PI-RADS score showed significant correlations with pathologic tumor volume (ρ = 0.81, P PET/MR imaging show good correlation with clinical-pathologic characteristics, such as postsurgical CAPRA score, which are related to prognosis in patients with newly diagnosed intermediate- to high-risk PCa. © RSNA, 2016 Online supplemental material is available for this article.

    Full Text Available To maximise the application of results of large-scale clinical trials, recruitment and retention of a diverse subject population is key. With commonly used algorithms (Snapshot, TLOVR, missing = failure, all withdrawals in HIV studies, regardless of reason, are classed as failures in efficacy analyses. Good subject compliance therefore improves statistical power and the quality of trial results. In four recent GSK/ViiV-sponsored phase IIIB/IV HIV ART-naïve studies (HEAT, KLEAN, APV109141 and ARIES, 24% of subjects withdrew and approximately 2/3 of these withdrawals (16% potentially were avoidable (i.e. not treatment related [1]. To increase subject compliance in the phase III, treatment-naïve studies of DTG (ING113086 “SPRING-2” and ING114467 “SINGLE”, a more robust subject compliance program focussing on understanding subject needs and building sponsor-site and site-subject relationships was implemented. The compliance program included opt-in study visit reminders, late study visit tracking, subject compliance support materials, subject transportation support, on-going site training, relationship management and presentations on prior withdrawal rates and associated risk factors for attrition at investigator meetings. Week 48 withdrawals, both overall and for potentially avoidable reasons, were considerably lower in SPRING-2 and SINGLE than historical HIV trials. Comparison of withdrawal rates prior to, and after implementation of robust patient compliance program. Addressing individual study subject needs with a customized approach in SPRING-2 and SINGLE contributed to considerably lower percentages of withdrawals than in historical HIV studies. Identifying the specific impact of a single subject compliance initiative is difficult as study compliance can be influenced by overall study design, investigational product tolerability profile, current standard of care and treatment access for the disease under study. However, consistently

    Full Text Available Although World Health Organization guidelines recommend clinical judgment and chest radiography for diagnosing tuberculosis in HIV-infected adults with unexplained cough and negative sputum smears for acid-fast bacilli, the diagnostic performance of this approach is unknown. Therefore, we sought to assess the accuracy of symptoms, physical signs, and radiographic findings for diagnosing tuberculosis in this population in a low-income country with a high incidence of tuberculosis.We performed a cross-sectional study enrolling consecutive HIV-infected inpatients with unexplained cough and negative sputum smears for acid-fast bacilli at Mulago Hospital in Kampala, Uganda. Trained medical officers prospectively collected data on standard symptoms and signs of systemic respiratory illness, and two radiologists interpreted chest radiographs in a standardized fashion. We calculated positive- and negative-likelihood ratios of these factors for diagnosing pulmonary tuberculosis (defined when mycobacterial cultures of sputum or bronchoalveolar lavage fluid were positive. We used both conventional and novel regression techniques to develop multivariable prediction models for pulmonary tuberculosis.Among 202 enrolled HIV-infected adults with negative sputum smears for acid-fast bacilli, 72 (36% had culture-positive pulmonary tuberculosis. No single factor, including respiratory symptoms, physical findings, CD4+ T-cell count, or chest radiographic abnormalities, substantially increased or decreased the likelihood of pulmonary tuberculosis. After exhaustive testing, we were also unable to identify any combination of factors which reliably predicted bacteriologically confirmed tuberculosis.Clinical and radiographic criteria did not help diagnose smear-negative pulmonary tuberculosis among HIV-infected patients with unexplained cough in a low-income setting. Enhanced diagnostic methods for smear-negative tuberculosis are urgently needed.

    Acute coronary syndrome (ACS) can be a diagnostic challenge in the emergency department (ED). Recently, the HEART score was developed, a simple bedside scoring system that quantifies risk of ischaemic events in patients with undifferentiated chest pain presenting in the ED. In this prospective cohort study, we compared the diagnostic accuracy of HEART score and clinical gestalt (clinical judgement) for diagnosing ACS in an unselected population of patients with chest pain presenting to the ED. HEART score (0-10) and clinical gestalt (low risk, intermediate risk or high risk of ACS) were prospectively determined in the ED in 255 patients presenting with chest pain by the treating physician. The reference standard was the presence of ACS, which was defined as either acute myocardial infarction (AMI) or the occurrence of a major adverse cardiac event within 6 weeks after presentation in the ED. 75 out of 255 patients (29%) had an ACS. A HEART score ≤3 had a lower negative likelihood ratio (0.15 (0.06-0.36)) for ACS than a low risk based on clinical gestalt (0.35 (0.19-0.64)), whereas a high HEART score ≥7 had a higher positive likelihood ratio (5.2 (3.2-8.5) vs 3.1 (2.2-4.4)). However, c-statistic of HEART score was not significantly different from clinical gestalt (0.81 (0.76-0.86) vs 0.79 (0.73-0.84), p=0.13). Our study demonstrates that HEART score and clinical gestalt have similar diagnostic accuracy for diagnosing ACS in an unselected population of patients with chest pain presenting in the ED.

    2018-02-01

    Full Text Available Introduction: Attention Deficit Hyperactivity Disorder (ADHD is the most common behavioral issue for children. One of the sleeping disorders most frequently related to ADHD is the Restless Legs Syndrome (RLS, characterized by an irresistible urge to move the legs, something that is generally associated with paresthesias and motor restlessness. The prevalence rate of RLS in children diagnosed with ADHD is close to 18%, but in Colombia, these cases have been hardly studied. Objective: To determine the frequency of RLS, in children with ADHD. Methods: A cross-sectional study, filled out by parents of children diagnosed with ADHD, were analyzed. This questionnaire contained clinical criteria for classifying ADHD according to the DSM-IV, as well as diagnostic criteria for RLS by the National Institutes of Health (2003. Results: A predominance rate of 65.6% in combined ADHD was observed in children with RLS criteria. Upon carrying out an exploratory data analysis, it was found that having a family history of RLS and belonging to the middle or low socioeconomic strata are conditions associated with the presence of RLS in children with ADHD, with a significant p (p < 0.000 and a PR of 4.47 (3.16-6.32. Conclusions: The prevalence of RLS was similar to the findings of other clinical investigations. However, it highlights new prevalence values in relation to the comorbidity between ADHD and RLS, suggesting the need for new clinical and therapeutic alternatives amidst the presence of both syndromes.

    Mycobacterium intracellulare is a major cause of Mycobacterium avium complex lung disease in many countries. Molecular studies have revealed several new Mycobacteria species that are closely related to M. intracellulare. The aim of this study was to re-identify and characterize clinical isolates from patients previously diagnosed with M. intracellulare lung disease at the molecular level. Mycobacterial isolates from 77 patients, initially diagnosed with M. intracellulare lung disease were re-analyzed by multi-locus sequencing and pattern of insertion sequences. Among the 77 isolates, 74 (96 %) isolates were designated as M. intracellulare based on multigene sequence-based analysis. Interestingly, the three remaining strains (4 %) were re-identified as "Mycobacterium indicus pranii" according to distinct molecular phylogenetic positions in rpoB and hsp65 sequence-based typing. In hsp65 sequevar analysis, code 13 was found in the majority of cases and three unreported codes were identified. In 16S-23S rRNA internal transcribed spacer (ITS) sequevar analysis, all isolates of both species were classified within the Min-A ITS sequevar. Interestingly, four of the M. intracellulare isolates harbored IS1311, a M. avium-specific element. Two of three patients infected with "M. indicus pranii" had persistent positive sputum cultures after antibiotic therapy, indicating the clinical relevance of this study. This analysis highlights the importance of precise identification of clinical isolates genetically close to Mycobacterium species, and suggests that greater attention should be paid to nontuberculous mycobacteria lung disease caused by "M. indicus pranii".

    The malaria burden in sub-Saharan Africa (SSA) has fallen substantially. Nevertheless, malaria remains a serious health concern, and Uganda ranks third in SSA in total malaria burden. Epidemiological studies of adult malaria in Uganda are scarce and little is known about rates of malaria in non-pregnant adult women. This pilot study assessed malaria prevalence among adult women from Wakiso district, historically a highly malaria endemic region. Adult women using public health services were screened for malaria, HIV and pregnancy. A physician-selected subset of women presenting to the Outpatient Department of Entebbe General Hospital (EGH) with current fever (axillary temperature ≥37.5 °C) or self-reporting fever during the previous 24 h, and a positive thick smear for malaria in the EGH laboratory were enrolled (n = 86). Women who self-identified as pregnant or HIV-positive were excluded from screening. Malaria infection was then assessed using HRP2/pLDH rapid diagnostic tests (RDTs) in all participants. Repeat microscopy and PCR were performed at a research laboratory for a subset of participants. In addition, 104 women without a history of fever were assessed for asymptomatic parasitaemia using RDT, and a subset of these women screened for parasitaemia using microscopy (40 women) and PCR (40 women). Of 86 women diagnosed with malaria by EGH, only two (2.3%) had malaria confirmed using RDT, subsequently identified as a Plasmodium falciparum infection by research microscopy and PCR. Subset analysis of hospital diagnosed RDT-negative participants detected one sub-microscopic infection with Plasmodium ovale. Compared to RDT, sensitivity, specificity and PPV of hospital microscopy were 100% (CI 19.8-100), 0% (CI 0-5.32) and 2.33% (CI 0.403-8.94) respectively. Compared to PCR, sensitivity, specificity and PPV of hospital microscopy were 100% (CI 31.0-100), 0% (CI 0-34.5) and 23.1% (CI 6.16-54.0), respectively. No malaria was detected among asymptomatic women

    The sleep-wake cycle is the most important circadian rhythm in man and thus constitutes an excellent indicator of internal equilibrium and of health. Sleep disorders, and particularly insomnia, affect a great percentage of the population. In daily practice, an inappropriate treatment may transform a bad sleeper into an insomniac dependent on pharmaceuticals for life. It is therefore necessary to give priority to non-chemical treatments in the management of insomnia. Acupuncture, which offers a personalized treatment, is particularly indicated for reharmonizing a disturbed sleep-wake cycle. Furthermore, there is an interesting similarity between the 5000-year-old theoretical basis of Chinese medicine and the recent scientific discoveries about man's internal rhythms. Clinical and statistical studies of the effects of acupuncture on insomnia are rare and evaluate only the subjective appreciation of sleep. Objective analysis of sleep by polysomnography permits evaluation of sleep architecture and visualizes the site and depth of action of the therapeutic method. Such studies have only been conducted in relation to pharmaceutical treatments. No such study has been carried out for acupuncture. A scientific and objective evaluation of the effects of acupuncture on insomnia by polysomnography could be not only of academic but mainly of great practical interest. If the efficiency of acupuncture is thus verified, this method could be integrated and proposed along with other classical therapeutic technics.

    The snug fit of a prosthetic socket over the residual limb can disturb thermal balance and put skin integrity in jeopardy by providing an unpleasant and infectious environment. The prototype of a temperature measurement and control (TM&C) system was previously introduced to resolve thermal problems related to prostheses. This study evaluates its clinical application in a setting with reversal, single subject design. The TM&C system was installed on a fabricated prosthetic socket of a man with unilateral transtibial amputation. Skin temperature of the residual limb without prosthesis at baseline and with prosthesis during rest and walking was evaluated. The thermal sense and thermal comfort of the participant were also evaluated. The results showed different skin temperature around the residual limb with a temperature decrease tendency from proximal to distal. The TM&C system decreased skin temperature rise after prosthesis wearing. The same situation occurred during walking, but the thermal power of the TM&C system was insufficient to overcome heat build-up in some regions of the residual limb. The participant reported no significant change of thermal sense and thermal comfort. Further investigations are warranted to examine thermography pattern of the residual limb, thermal sense, and thermal comfort in people with amputation.

    The objectives of the investigation were to evaluate the effect of a sound processor upgrade on the speech reception threshold in noise and to collect long-term safety and efficacy data after 2½ to 5 years of device use of direct acoustic cochlear implant (DACI) recipients. The study was designed as a mono-centric, prospective clinical trial. Tertiary referral center. Fifteen patients implanted with a direct acoustic cochlear implant. Upgrade with a newer generation of sound processor. Speech recognition test in quiet and in noise, pure tone thresholds, subject-reported outcome measures. The speech recognition in quiet and in noise is superior after the sound processor upgrade and stable after long-term use of the direct acoustic cochlear implant. The bone conduction thresholds did not decrease significantly after long-term high level stimulation. The new sound processor for the DACI system provides significant benefits for DACI users for speech recognition in both quiet and noise. Especially the noise program with the use of directional microphones (Zoom) allows DACI patients to have much less difficulty when having conversations in noisy environments. Furthermore, the study confirms that the benefits of the sound processor upgrade are available to the DACI recipients even after several years of experience with a legacy sound processor. Finally, our study demonstrates that the DACI system is a safe and effective long-term therapy.

    Many people routinely criticise themselves. While self-criticism is largely unproblematic for most individuals, depressed patients exhibit excessive self-critical thinking, which leads to strong negative affects. We used functional magnetic resonance imaging in healthy subjects (N = 20) to investigate neural correlates and possible psychological moderators of self-critical processing. Stimuli consisted of individually selected adjectives of personally negative content and were contrasted with neutral and negative non-self-referential adjectives. We found that confrontation with self-critical material yielded neural activity in regions involved in emotions (anterior insula/hippocampus–amygdala formation) and in anterior and posterior cortical midline structures, which are associated with self-referential and autobiographical memory processing. Furthermore, contrasts revealed an extended network of bilateral frontal brain areas. We suggest that the co-activation of superior and inferior lateral frontal brain regions reflects the recruitment of a frontal top–down pathway, representing cognitive reappraisal strategies for dealing with evoked negative affects. In addition, activation of right superior frontal areas was positively associated with neuroticism and negatively associated with cognitive reappraisal. Although these findings may not be specific to negative stimuli, they support a role for clinically relevant personality traits in successful regulation of emotion during confrontation with self-critical material.

    Under what conditions the work activity may be structuring health and in which ones can become a source of disease and suffering? How explain the current situation of deterioration and increased mental pathology in relation to work? The job must be conceived as a trigger among others, or could play a specific role in the etiology of various psychological and psychosomatic pictures? This article addresses these questions from the perspective of Psychodynamic of work. Based on the theory of living labor developed by C. Dejours, the article analyzes the dynamic pleasure-suffering in relation to work and the role of defensive mechanisms in those dynamics. In turn, it characterized the current epidemiological situation, describing the prevalent pathologies related to mental health and work. Finally, the article exposes the thesis of Psychodynamic of work regarding the increase and aggravation of these pathologies. The article aims to present the main axes of Psychodynamics of Work, which is a theory and clinical practice whose object is the psychodynamic analysis of subjective and intersubjective processes mobilized by work situations.

    the subjects had a higher preference for multimodal learning. With our preliminary data, we conclude that the students in our clinical set up preferred a multimodal and a more of kinesthetic method of learning. To meet their needs, variations in the teaching, learning and the examination must be implemented. If not, the students with a high kinesthetic preference for perception and learning may be at the losing end.

    Full Text Available Recent research findings suggest that many children with Autism Spectrum Disorders (ASD demonstrate delayed and atypical motor achievements. It has now become clear that a more holistic, integrative and multi-disciplinary intervention is required to effectively address the motor-related impairments of this population. It is also crucial to ensure that this group of clients has access to early physical therapy (PT interventions. Despite accumulating research on physical interventions, little is known about intervention model for implementation at a national level. This report introduces a model that uniquely illustrates implementation of PT services for a large number of children with ASD. The model has been operating for the past two years in one country (Israel, and includes an optional implementation model of PT practice settings for young children diagnosed with ASD. The Israeli setting offers a unique opportunity for implementing PT services for a multitude of children with ASD on a regular basis as an accepted/needed service. The initial outcomes of the present implementation suggest that an intensive PT intervention program might enhance therapeutic outcomes for this population, and contribute to our knowledge on the

  13. Recognising domestic violence in clinical practice using the diagnoses of posttraumatic stress disorder, depression and low self-esteem.

    This discussion paper reviews the health impacts, physical and mental, of domestic violence and explores the link between domestic violence and psychological symptoms. This paper focuses more on posttraumatic stress disorder (PTSD) than depression and low self-esteem because doctors are less familiar with PTSD. The barriers preventing health workers from detecting domestic violence are reviewed and the fear of health professionals that asking about trauma can harm patients is explored. The article then outlines practical strategies to improve detection of domestic violence using patients' presenting psychological symptoms and the diagnoses frequently associated with domestic violence namely, PTSD, depression and low self-esteem. It is argued that it is inadvisable to try to implement a policy of screening for domestic violence in general practice when the public health model is currently inappropriate. The paper discusses why the diagnostic frameworks of depression and PTSD are helpful in general practice, not only in detecting domestic violence but in working with the patient to establish trust and ways forward that can be tailored to meet the needs of the patient and their children. Patients' and professionals' dilemmas about what to do once domestic violence is detected are briefly explored.

    Patients with psychogenic nonepileptic seizures (PNES) are heavy users of emergency and nonemergency health care. We performed a 1-year prospective audit of use of a group of PNES-related health care items in patients with newly diagnosed (mean duration: 7.3 months) PNES from PNES onset to diagnosis and from diagnosis to 6 months postdiagnosis. Twenty-eight patients (20 women, age: 34±16 years) were responsible for 14 general practitioner home visits, 31 ambulance calls, 34 emergency department visits, 21 hospital admissions (66 inpatient days), 8 MRI scans, 24 CT scans, 2 standard EEGs, 28 short video EEG recordings, and 5 ambulatory EEG recordings. In the 6 months following diagnosis, there were 2 emergency department visits (94.1% reduction), no hospital admissions (100% reduction), 2 ambulance calls, no general practitioner visits, 1 MRI scan, and no CT scans or EEGs. The immediacy of this marked health care demand reduction suggests that the relationship between presentation of diagnosis and health care demand reduction is causal. Copyright © 2011 Elsevier Inc.

    Motion capture of all degrees of freedom of the hand collected during performance of daily living activities remains challenging. Instrumented gloves are an attractive option because of their higher ease of use. However, subject-specific calibration of gloves is lengthy and has limitations for individuals with disabilities. Here, a calibration procedure is presented, consisting in the recording of just a simple hand position so as to allow capture of the kinematics of 16 hand joints during daily life activities even in case of severe injured hands. 'across-subject gains' were obtained by averaging the gains obtained from a detailed subject-specific calibration involving 44 registrations that was repeated three times on multiple days to 6 subjects. In additional 4 subjects, joint angles that resulted from applying the 'across-subject calibration' or the subject-specific calibration were compared. Global errors associated with the 'across-subject calibration' relative to the detailed, subject-specific protocol were small (bias: 0.49°; precision: 4.45°) and comparable to those that resulted from repeating the detailed protocol with the same subject on multiple days (0.36°; 3.50°). Furthermore, in one subject, performance of the 'across-subject calibration' was directly compared to another fast calibration method, expressed relative to a videogrammetric protocol as a gold-standard, yielding better results.

    Temporomandibular joint disorder (TMD) is a complex musculoskeletal disorder that presents with pain, limited jaw opening, and abnormal noises in the temporomandibular joint. Despite the significant impact that TMD has in terms of suffering and financial burden, relatively few new treatments have emerged; therefore, development of novel treatments to treat TMD pain remains a high priority. The rationale of this study was to use a double-blind, vehicle-controlled clinical trial to evaluate the effects of a high-concentration (8%) capsaicin cream on TMD. This is based on the hypothesis that targeting TRP vanilloid subfamily member 1 (TRPV1) for pain control may provide a novel method for pain relief in TMD patients. TRPV1 is primarily expressed on a population of nociceptive-specific neurons and provides a candidate target for the development of pain treatments. Capsaicin is the primary agonist for TRPV1 and has been used previously in relatively low doses (0.025% to 0.075%) as a therapeutic for a variety of pain disorders, including postherpetic neuralgia and osteoarthritis; however, analgesic efficacy remains equivocal. TMD and healthy control subjects were assigned to either an active capsaicin or vehicle control group. The treatments were applied for 2 h and then removed. Quantitative sensory testing (QST) was completed prior to drug application (baseline), 2 h after drug application, and 1 wk later. Perceived pain intensity was measured using a visual analog scale (VAS) following capsaicin or vehicle cream application. Significantly lower pain was reported in the week after application in the capsaicin-treated TMD subjects. For QST measures, there was a decreased thermal pain threshold 2 h after capsaicin application for both the control and TMD groups, but this resolved within a week. Capsaicin had no effect on pressure pain threshold or mechanical sensitivity in both TMD and healthy individuals. This study demonstrates that 8% topical capsaicin therapy is a

    To assess clinical outcomes and cost-effectiveness of using a two-layer cohesive compression bandage (TLCCB; Coban 2) compared with a two-layer compression system (TLCS; KTwo) and a four-layer compression system (FLCS; Profore) in treating newly-diagnosed venous leg ulcers (VLUs) in clinical practice in the UK, from the perspective of the NHS. This was a retrospective cohort analysis of the case records of patients with newly-diagnosed VLUs randomly extracted from The Health Improvement Network (THIN) database (a nationally representative database of clinical practice among patients registered with general practitioners in the UK) who were treated with either TLCCB (n=200), TLCS (n=200) or FLCS (n=200). The clinical outcomes and cost-effectiveness of the alternative compression systems were estimated over six months after starting treatment. Patients' mean age was 72 years and 58% were female. Time from wound onset to the start of compression was a mean of two months, and when starting compression the wound size was a mean of 45 cm(2). The distribution of healing was significantly different between the three groups; 76% of wounds in the TLCCB group healed by six months compared with 70% and 64% in the TLCS and FLCS groups, respectively (p=0.006). Time to healing was significantly less in the TLCCB group compared with the two other groups (p=0.003). Patients in the TLCCB group experienced better health-related quality of life over six months (0.413 quality-adjusted life years (QALYs) per patient), compared with the TLCS and FLCS groups (0.404 and 0.396 QALYs per patient, respectively). The mean six-month NHS management cost was £3045, £3842 and £4480 per patient in the TLCCB, TLCS and FLCS groups, respectively. Real-world evidence demonstrates that treating newly-diagnosed VLUs with TLCCB, compared with the other two compression systems, affords a more cost-effective use of NHS-funded resources in clinical practice since it resulted in an increased healing rate

  20. Assessment of the accuracy of portable monitors for halitosis evaluation in subjects without malodor complaint. Are they reliable for clinical practice?

    Directory of Open Access Journals (Sweden)

    Denise Pinheiro Falcão

    Full Text Available Abstract Halitosis is defined as a foul odor emanated from the oral cavity, with great impact in quality of life and social restraints. Recently, the use of Breath Alert™ in research increased significantly. Halimeter™, another portable device, is often used in clinical practice. Nevertheless, not many studies have verified the accuracy and compared the results of both devices simultaneously. Objective: To verify the accuracy of Breath Alert™ and Halimeter™ in patients without chief complaint of halitosis, using the organoleptic test (OT as "gold standard." The second aim was to verify whether their concomitant use could enhance the diagnostic accuracy of halitosis. Material and Methods: A cross-sectional analytical study was performed. The quality of expired air of 34 subjects without chief complaint of halitosis was assessed. Two experienced examiners carried out the OT. Afterward, a third blinded examiner performed Halimeter™ (HT and Breath Alert™ (BA tests. Results: The OT identified halitosis in 21 subjects (62%. The area under the ROC curve (95% confidence interval was 0.67 (0.48-0.85 and 0.54 (0.34-0.75 for HT and BA, respectively. The accuracy for HT and BA was 59% and 47%, respectively. The combined usage of HT and BA provided 11 positive results, being 9 subjects (43% out of the total of 21 positive cases. Conclusions: Halimeter™ and Breath Alert™ were not able to diagnose halitosis in non-complainer subjects at the same level as the organoleptic examination, since their accuracy were low. Our results suggest that such portable devices are not reliable tools to assess halitosis and may neglect or misdiagnose a considerable number of patients in clinical practice.

    Full Text Available Abstract Background Many diabetic patients fear visual loss as the worst consequence of diabetes. In most studies the main eye pathology is assigned as the cause of visual impairment. This study analysed a broad range of possible ocular and non-ocular predictors of visual impairment prospectively in patients newly diagnosed with clinical type 2 diabetes. Methods Data were from a population-based cohort of 1,241 persons newly diagnosed with clinical, often symptomatic type 2 diabetes aged ≥ 40 years. After 6 years, 807 patients were followed up. Standard eye examinations were done by practising ophthalmologists. Results At diabetes diagnosis median age was 65.5 years. Over 6 years, the prevalence of blindness (visual acuity of best seeing eye ≤ 0.1 rose from 0.9% (11/1,241 to 2.4% (19/807 and the prevalence of moderate visual impairment (> 0.1; Conclusions In a comprehensive assessment of predictors of visual impairment, even in a health care system allowing self-referral to free eye examinations, treatable eye pathologies such as DR and cataract emerge together with age as the most notable predictors of continued visual loss after diabetes diagnosis. Our results underline the importance of eliminating barriers to efficient eye care by increasing patients' and primary care practitioners' awareness of the necessity of regular eye examinations and timely surgical treatment.

    Between 1978 and 1983, 80 patients with Hodgkin's disease (HD) in clinical Stage I-III had computed tomography (CT) of the abdomen and pelvis and lymphography (LAG) prior to staging laparatomy with multiple lymph node biopsies at Stanford University Medical Center. There were 224 biopsied nodal sites. The sensitivity and specificity for CT to determine the status of biopsied paraortic and iliac nodes was .61 and .91 vs. .94 and .90 for LAG. CT appeared of even lower sensitivity (.13) in evaluating splenic hilar, celiac axis and portal nodes. Including all biopsy proven subdiaphragmatic nodal sites, CT's sensitivity to diagnose the presence of subdiaphragmatic adenopathy was .38 vs. .52 in LAG. Assessment of the final pathological stage was more successful by LAG (.61) than by CT (.49). Positive and negative predictive values of both tests indicate higher reliability of LAG results as regards individual intraabdominal nodes (LAG .71, .98 vs. CT .58, .86), the entire subdiaphragmatic nodal area (LAG .79, .77 vs. CT .61, .71) and prediction of final pathological stage. LAG appeared to be the more useful test during initial staging of newly diagnosed and untreated patients with HD. None of the test for itself or in combination can replace laparatomy when exact information is necessary for further clinical decisions.

    Emerging antibiotic resistance among pathogenic bacteria, paired with their ability to form biofilms on medical and technical devices, represents a serious problem for effective and long-term decontamination in health-care environments and gives rise to an urgent need for new antimicrobial materials. Here we present the impact of AGXX ® , a novel broad-spectrum antimicrobial surface coating consisting of micro-galvanic elements formed by silver and ruthenium, on the transcriptome of Enterococcus faecalis. A clinical E. faecalis isolate was subjected to metal stress by growing it for different periods in presence of the antimicrobial coating or silver-coated steel meshes. Subsequently, total RNA was isolated and next-generation RNA sequencing was performed to analyze variations in gene expression in presence of the antimicrobial materials with focus on known stress genes. Exposure to the antimicrobial coating had a large impact on the transcriptome of E. faecalis. After 24min almost 1/5 of the E. faecalis genome displayed differential expression. At each time-point the cop operon was strongly up-regulated, providing indirect evidence for the presence of free Ag + -ions. Moreover, exposure to the antimicrobial coating induced a broad general stress response in E. faecalis. Genes coding for the chaperones GroEL and GroES and the Clp proteases, ClpE and ClpB, were among the top up-regulated heat shock genes. Differential expression of thioredoxin, superoxide dismutase and glutathione synthetase genes indicates a high level of oxidative stress. We postulate a mechanism of action where the combination of Ag + -ions and reactive oxygen species generated by AGXX ® results in a synergistic antimicrobial effect, superior to that of conventional silver coatings.

    Trunk muscle timing impairment has been associated with nonspecific low back pain (NSLBP), but this finding has not been consistent. This study investigated trunk muscle timing in a subgroup of patients with NSLBP attributed to movement coordination impairment (MCI) and matched asymptomatic controls in response to a rapid arm-raising task. Twenty-one NSLBP subjects and 21 matched controls had arm motion and surface EMG data collected from seven bilateral trunk muscles. Muscle onset and offset relative to deltoid muscle activation and arm motion, duration of muscle burst and abdominal-extensor co-contraction time were derived. Trunk muscle onset and offset latencies, and burst and co-contraction durations were not different (p > .05) between groups. Patterns of trunk muscle activation and deactivation relative to arm motion were not different. Task performance was similar between groups. Trunk muscle timing does not appear to be an underlying impairment in the subgroup of NSLBP with MCI.

    The aim of this study was to develop and test, for the first time, a multivariate diagnostic classifier of attention deficit hyperactivity disorder (ADHD) based on EEG coherence measures and chronological age. The participants were recruited in two specialised centres and three schools in Reykjavik. The data are from a large cross-sectional cohort of 310 patients with ADHD and 351 controls, covering an age range from 5.8 to 14 years. ADHD was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM-IV) criteria using the K-SADS-PL semistructured interview. Participants in the control group were reported to be free of any mental or developmental disorders by their parents and had a score of less than 1.5 SDs above the age-appropriate norm on the ADHD Rating Scale-IV. Other than moderate or severe intellectual disability, no additional exclusion criteria were applied in order that the cohort reflected the typical cross section of patients with ADHD. Diagnostic classifiers were developed using statistical pattern recognition for the entire age range and for specific age ranges and were tested using cross-validation and by application to a separate cohort of recordings not used in the development process. The age-specific classification approach was more accurate (76% accuracy in the independent test cohort; 81% cross-validation accuracy) than the age-independent version (76%; 73%). Chronological age was found to be an important classification feature. The novel application of EEG-based classification methods presented here can offer significant benefit to the clinician by improving both the accuracy of initial diagnosis and ongoing monitoring of children and adolescents with ADHD. The most accurate possible diagnosis at a single point in time can be obtained by the age-specific classifiers, but the age-independent classifiers are also useful as they enable longitudinal monitoring of brain function.

    Delays in diagnosis occur with complex regional pain syndrome (CRPS). We define and prospectively demonstrate that novel bedside tests measuring body perception disruption can identify patients with CRPS postfracture. The objectives of our study were to define and validate 4 bedside tests, to identify the prevalence of positive tests in patients with CRPS and other chronic pain conditions, and to assess the clinical utility (sensitivity, specificity, positive predictive value, negative predictive value) for identifying CRPS within a Fracture cohort. This was a single UK teaching hospital prospective cohort study with 313 recruits from pain-free volunteers and patients with chronic pain conditions.Four novel tests were Finger Perception (FP), Hand Laterality identification (HL), Astereognosis (AS), and Body Scheme (BS) report. Five questionnaires (Brief Pain Inventory, Upper Extremity Functional Index, Lower Extremity Functional Index, Neglect-like Symptom Questionnaire, Hospital Anxiety and Depression Score) assessed the multidimensional pain experience. FP and BS were the best performing tests. Prospective monitoring of fracture patients showed that out of 7 fracture patients (total n=47) who had both finger misperception and abnormal BS report at initial testing, 3 developed persistent pain with 1 having a formal diagnosis of CRPS. Novel signs are reliable, easy to perform, and present in chronic pain patients. FP and BS have significant clinical utility in predicting persistent pain in a fracture group thereby allowing targeted early intervention.

    This study aimed to develop and validate a Structured Clinical Interview for Internet Gaming Disorder (SCI-IGD) in adolescents. First, we generated preliminary items of the SCI-IGD based on the information from the DSM-5 literature reviews and expert consultations. Next, a total of 236 adolescents, from both community and clinical settings, were recruited to evaluate the psychometric properties of the SCI-IGD. First, the SCI-IGD was found to be consistent over the time period of about one month. Second, diagnostic concordances between the SCI-IGD and clinician's diagnostic impression were good to excellent. The Likelihood Ratio Positive and the Likelihood Ratio Negative estimates for the diagnosis of SCI-IGD were 10.93 and 0.35, respectively, indicating that SCI-IGD was 'very useful test' for identifying the presence of IGD and 'useful test' for identifying the absence of IGD. Third, SCI-IGD could identify disordered gamers from non-disordered gamers. The implications and limitations of the study are also discussed.

    To characterize adult patients with sleep apnea attending Pereira's sleep apnea clinic between July and August 2011. Cross-sectional descriptive study. A personal semi-structured survey was performed, with full medical history, focused on perceived symptoms of mental and non-mental comorbidity. Fourty-three patients with diagnosis of sleep apnea were evaluated. These were compared with 21 patients without this diagnosis. The social demographic characteristics were similar to that reported in the literature. There were statistical significances for snoring, sleep apnea, corporal mass index, waist/hip index and dyslipidemia. The logistic regression analysis showed sex, Pittsburgh's quality of sleep index and body mass index as predictor variables. There are clinical and anthropometrics variables that can help the health professionals to suspect a sleep apnea diagnosis in a patient and provide better treatment to decrease its morbidity and mortality.

    Full Text Available Objectives: This study was carried out to compare the Sweet Bee Venom (referred to as Sweet BV hereafter acupuncture parallel treatment to treatment with acupuncture only for the patient diagnosed with lumbar spine sprain and find a better treatment. Methods: The subjects were patients diagnosed with lumbar spine sprain and hospitalized at Suncheon oriental medical hospital, which was randomly divided into sweet BV parallel treatment group and acupuncture-only group, and other treatment conditions were maintained the same. Then,VAS (Visual Analogue Scale was used to compare the difference in the treatment period between the two groups from VAS 10 to VAS 0, from VAS 10 to VAS 5, and from VAS 5 to VAS 0. Result & Conclusion: Sweet BV parallel treatment group and acupuncture-only treatment group were compared regarding the respective treatment period, and as the result, the treatment period from VAS 10 to VAS 5 was significantly reduced in sweet BV parallel treatment group compared to the acupuncture-only treatment group, but the treatment period from VAS 5 to VAS 0 did not show a significant difference. Therefore, it can be said that sweet BV parallel treatment is effective in shortening the treatment period and controlling early pain compared to acupuncture-only treatment.

Nutritional assessment has three main aims: to define the type and severity of malnutrition; to identify high risk patients; to monitor the efficacy of nutritional support. The problems associated with the various methods to assess the nutritional state and the applications of nutritional assessment in clinical practice are presented and discussed.

    This study presents a new inventory, the Attention and Executive Function Rating Inventory (ATTEX), and examines the psychometric properties and the clinical utility of ATTEX in identifying the attention deficit hyperactivity disorder combined type (ADHD-C) and the ADHD predominantly inattentive type (ADHD-I) in school environments. A normative sample of Finnish 7- to 15-year-old children and adolescents (N = 701) and a clinical sample consisting of children with ADHD-C (N = 190) and ADHD-I (N = 25) were examined with the ATTEX and the ADHD Rating Scale-IV. The ATTEX and its scales had good internal consistency reliability (0.67-0.98) and criterion validity (0.68-0.95). Normative data was provided for the total normative sample and for boys and girls separately. Gender differences were noted in the ATTEX scores, boys having consistently higher scores on all ATTEX scales. The effect of age was significant only for one of the ten scales, the Motor hyperactivity scale, 7-year-olds having more problems of hyperactivity than 14-year-olds. Lower parent education level and the child's learning difficulties were related to higher ratings of EF problems in ATTEX. When different cutoff scores for boys and girls were applied, ATTEX was sensitive in identifying children with attention deficit disorders. In addition, ATTEX was accurate in differentiating children with ADHD-I from children with ADHD-C. In this Finnish sample, ATTEX showed solid psychometric properties and could be used as a reliable tool in the diagnostic evaluation of ADHD-C and ADHD-I. © 2010 The Authors.

    It has been reported that deep breathing could reduce blood pressures (BP) in general. It is also known that BP is decreased during inhalation and increased during exhalation. Therefore, the measured BPs could be potentially different during deep breathing with different lengths of inhalation and exhalation. This study aimed to quantitatively investigate the effect of different respiratory patterns on BPs. Forty healthy subjects (20 males and 20 females, aged from 18 to 60 years) were recruited. Systolic and diastolic BPs (SBP and DBP) were measured using a clinically validated automated BP device. There were two repeated measurement sessions for each subject. Within each session, eight BP measurements were performed, including 4 measurements during deep breathing with different respiratory patterns (Pattern 1: 4.5 s vs 4.5 s; Patter 2: 6 s vs 2 s; Pattern 3: 2 s vs 6 s; and Pattern 4: 1.5 s vs 1.5 s, respectively for the durations of inhalation and exhalation) and additional 4 measurements from 1 min after the four different respiratory patterns. At the beginning and end of the two repeated measurement sessions, there were two baseline BP measurements under resting condition. The key experimental results showed that overall automated SBP significantly decreased by 3.7 ± 5.7 mmHg, 3.9 ± 5.2 mmHg, 1.7 ± 5.9 mmHg and 3.3 ± 5.3 mmHg during deep breathing, respectively for Patterns 1, 2, 3 and 4 (all p Pattern 3). Similarly, the automated DBPs during deep breathing in pattern 1, 2 and 4 decreased by 3.7 ± 5.0 mmHg, 3.7 ± 4.9 mmHg and 4.6 ± 3.9 mmHg respectively (all p Pattern 3 with a decrease of 1.0 ± 4.3 mmHg, p = 0.14). Correspondingly, after deep breathing, automated BPs recovered back to normal with no significant difference in comparison with baseline BP (all p > 0.05, except for SBP in Pattern 4). In summary, this study has quantitatively demonstrated that the measured automated BPs decreased

    Background Double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) is one of the most widely conducted gastric cancer screening methods. It has been executed to find gastric cancer, but has not been usually executed to detect premalignant atrophic mucosa of stomach. To understand the meaning of UGI-XR-based atrophic gastritis, we analyzed its association with several causative factors including Helicobacter pylori (HP) infection. Methods We evaluated 6,901 healthy adults in Japan. UGI-XR-based atrophic gastritis was diagnosed based on the irregular shape of areae gastricae and its expansion in the stomach. Results Of the 6,433 subjects with no history of HP eradication and free from gastric acid suppressants, 1,936 were diagnosed as UGI-XR-based atrophic gastritis (mild: 234, moderate: 822, severe: 880). These were univariately associated with serum HP IgG and serum pepsinogen I/II ratio with statistical significance. The multiple logistic analysis calculating standardized coefficients (β) and odds ratio (OR) demonstrated that serum HP IgG (β = 1.499, OR = 4.48), current smoking (β = 0.526, OR = 1.69), age (β = 0.401, OR = 1.49), low serum pepsinogen I/II ratio (β = 0.339, OR = 1.40), and male gender (β = 0.306, OR = 1.36) showed significant positive association with UGI-XR-based atrophic gastritis whereas drinking and body mass index did not. Among the age/sex/smoking/drinking-matched 227 pairs derived from chronically HP-infected and successfully HP-eradicated subjects, UGI-XR-based atrophic gastritis was detected in 99.1% of the former but in only 59.5% of the latter subjects (pgastritis was detected in 13 of 14 HP-positive proton pump inhibitor users (92.9%) and 33 of 34 HP-positive histamine H2-receptor antagonist users (97.1%), which are not significantly different from gastric acid suppressant-free subjects.

    Full Text Available Replicating smallpox vaccines can cause severe complications in individuals with atopic dermatitis (AD. Prior studies evaluating Modified Vaccinia Ankara virus (MVA, a non-replicating vaccine in humans, showed a favorable safety and immunogenicity profile in healthy volunteers.This Phase II study compared the safety and immunogenicity of MVA enrolling groups of 350 subjects with AD (SCORAD ≤ 30 and 282 healthy subjects.Subjects were vaccinated twice with MVA, each dose given subcutaneously 4 weeks apart. Adverse events, cardiac parameters, and the development of vaccinia virus humoral immune responses were monitored.The overall safety of the vaccine was similar in both groups. Adverse events affecting skin were experienced significantly more often in subjects with AD, but the majority of these events were mild to moderate in intensity. Seroconversion rates and geometric mean titers for total and neutralizing vaccinia-specific antibodies in the AD group were non-inferior compared to the healthy subjects.The size of the study population limited the detection of serious adverse events occurring at a frequency less than 1%.MVA has a favorable safety profile and the ability to elicit vaccinia-specific immune responses in subjects with AD.ClinicalTrials.gov NCT00316602.

  18. Patient perspectives on the experience of being newly diagnosed with HIV in the emergency department/urgent care clinic of a public hospital.

    Katerina A Christopoulos

    Full Text Available We sought to understand patient perceptions of the emergency department/urgent care (ED/UC HIV diagnosis experience as well as factors that may promote or discourage linkage to HIV care. We conducted in-depth interviews with patients (n=24 whose HIV infection was diagnosed in the ED/UC of a public hospital in San Francisco at least six months prior and who linked to HIV care at the hospital HIV clinic. Key diagnosis experience themes included physical discomfort and limited functionality, presence of comorbid diagnoses, a wide spectrum of HIV risk perception, and feelings of isolation and anxiety. Patients diagnosed with HIV in the ED/UC may not have their desired emotional supports with them, either because they are alone or they are with family members or friends to whom they do not want to immediately disclose. Other patients may have no one they can rely on for immediate support. Nearly all participants described compassionate disclosure of test results by ED/UC providers, although several noted logistical issues that complicated the disclosure experience. Key linkage to care themes included the importance of continuity between the testing site and HIV care, hospital admission as an opportunity for support and HIV education, and thoughtful matching by linkage staff to a primary care provider. ED/UC clinicians and testing programs should be sensitive to the unique roles of sickness, risk perception, and isolation in the ED/UC diagnosis experience, as these things may delay acceptance of HIV diagnosis. The disclosure and linkage to care experience is crucial in forming patient attitudes towards HIV and HIV care, thus staff involved in disclosure and linkage activities should be trained to deliver compassionate, informed, and thoughtful care that bridges HIV testing and treatment sites.

    Schizoaffective disorder is viewed as a heterogeneous diagnosis among psychotic illnesses. Different diagnostic systems differ in their definition with DSM (-IIIR, -IV, and -V) providing a narrower definition than RDC and ICD-10. It is unclear whether this difference is reflected in patient samples diagnosed according to different diagnostic systems. Exploratory study based on a systematic review of studies of schizoaffective disorder samples diagnosed by either RDC and ICD-10 (group of "broad criteria") or DSM-IIIR and -IV ("narrow criteria"); comparison (by Mann-Whitney-U-tests) of key characteristics, such as age, number of hospitalizations, or scores in psychometric tests, between more broadly and more narrowly defined schizoaffective disorder samples using standard deviations as a measurement of heterogeneity as well as weighted means and percentages. To reduce selection bias only studies including schizoaffective patient samples together with affective disorder and schizophrenia samples were selected. 55 studies were included, 14 employing RDC, 4 ICD-10, 20 DSM-IIIR, and 17 DSM-IV. Thirteen characteristics were compared: patients diagnosed according to broader criteria had fewer previous hospitalizations (2.2 vs. 5.4) and were both less often male (42 vs. 51%) and married (21 vs. 40%). Heterogeneity was similar in both groups but slightly higher in RDC and ICD-10 samples than in DSM-IIIR and -IV-samples: +4% regarding demographic and clinical course data and +13% regarding psychometric tests (pooled SD). Secular trends and different designs may have confounded the results and limit generalizability. Some comparisons were underpowered. Differences in diagnostic criteria are reflected in key characteristics of samples. The association of larger heterogeneity with wider diagnostic criteria supports employing standard deviations as a measurement of heterogeneity. Copyright © 2013 Elsevier B.V. All rights reserved.

  20. Estimation of the true incidence of lactic acidosis within the Lighthouse Clinic cohort, and the likely magnitude of missed diagnoses in the region

    Full Text Available Introduction: Lactic acidosis is one of the most serious side effects associated with ART, most commonly associated with stavudine. Clinical features are non-specific and specialist laboratory capabilities are essential to confirm the diagnosis, making under-diagnosis likely in resource-constrained settings. Lighthouse Trust is a tertiary referral ART centre with over 23,500 patients on ART. The adjacent University of North Carolina Project laboratory, also serving Kamuzu Central Hospital, has been the only site processing lactate tests in Central Zone for many years. Our objective was to quantify the true incidence within our cohort, and estimate the likely degree of historical missed diagnoses from less central ART clinics. Methods: All high lactate results between June 2010 and June 2013 were treated as cases, and cross referenced with the Lighthouse database. Patients transferring in to Lighthouse within one month prior to diagnosis were assumed to have been referred due to their lactic acidosis, and moved to the Central Zone cohort to avoid referral bias. Routinely collected quarterly ART cohort data for both Lighthouse and the entire Central Zone were analyzed. Results: Over the three-year period, from within the Lighthouse cohort, there were 138 cases: 74% were female, median duration on ART was 14 months (IQR 10–26, and 98.5% were attributable to stavudine (only two cases to zidovudine. Over this period, the average number of patients taking stavudine at Lighthouse was 10,960 (3,600 on zidovudine. For the whole Central Zone (minus Lighthouse patients there were 61,000 on stavudine (4,830 on zidovudine, yet only 124 cases of lactic acidosis were apparently diagnosed from within this cohort. Conclusions: Although cases may, of course, also have been missed at Lighthouse, as a tertiary referral centre the rate observed is likely to be closer to the true incidence. Over the three years, with 138 cases from the 10,960 patients taking

    The first objective of this study was to compare the written expression competence of young adults with attention deficit hyperactivity disorder (ADHD) with that of young adults without ADHD on three types of measures: indicators of the story's microstructure with regard to productivity and morphosyntax; indicators of the macrostructure (story grammar); and expressions of the mental states of the story's characters (internal state language). The second objective consisted of determining the relationships among the different narrative writing measures and the ADHD behavior ratings of inattention and hyperactivity obtained using the family observer report. The sample was composed of 54 participants, aged from 18 to 24, divided equally into a group with a childhood clinical diagnosis of combined subtype ADHD and a control group without ADHD. Written composition was assessed using a narrative task based on a sequence of images. As expected, the young adults with ADHD obtained significantly worse results than the control group on the majority of the parameters of the story's microstructure and macrostructure. Likewise, they included a significantly lower number of terms about the characters' mental states. A correlation was also observed between measures of narrative competence and core symptoms of ADHD, as well as between the use of words with an emotional content and estimations related to core symptoms of ADHD. The findings of this study point out that expressive writing should be assessed in individuals with ADHD as part of screening and comprehensive evaluation. More research is needed to design and implement effective interventions in this area. Copyright © 2013 Elsevier Ltd. All rights reserved.

    In acute myeloid leukemia (AML), the leukemia initiating cells (LICs) or leukemia stem cells (LSCs) is found within the CD34+CD38- cell compartment. The LICs subpopulation survives chemotherapy and is most probable the cause of minimal residual disease (MRD), which in turn is thought to cause relapse. The aim of this study was to determine the prognostic value of the percentage of LICs in blasts at diagnosis. The percentage of LICs in the blast population was determined at diagnosis using a unique Flow-FISH analysis, which applies fluorescent in situ hybridization (FISH) analysis on flow cytometry sorted cells to distinguish LICs within the CD34+CD38- cell compartment. Fourty-five AML patients with FISH-detectable cytogenetic abnormalities treated with standardized treatment program were retrospectively included in the study. Correlations with overall survival (OS), events-free survival (EFS) and cumulative incidence of relapse (CIR) were evaluated with univariate and multivariate analysis. The percentage of LICs is highly variable in patients with acute myeloid leukemia, ranged from 0.01% to 52.8% (median, 2.1%). High LIC load (≥1%) negatively affected overall survival (2-year OS: 72.57% vs. 16.75%; P = 0.0037) and events-free survival (2-year EFS: 67.23% vs. 16.33%; P = 0.0018), which was due to an increased cumulative incidence of relapse (2-year CIR: 56.7% vs. 18.0%; P = 0.021). By multivariate analysis, high LIC load retained prognostic significance for OS and EFS. In the present study, we established the Flow-FISH protocol as a useful method to distinguish normal and leukemic cells within the CD34+CD38- cell subpopulation. The high percentage of LICs at diagnosis was significantly correlated with increased risk of poor clinical outcome.

    Several studies have evaluated the relationship between diabetes mellitus (DM) and tuberculosis (TB), but the nature of this relationship is not fully understood. TB incidence may be influenced by immunosuppression from DM, but this association may be confounded by other clinical and socioeconomic factors. We aimed to assess socio-demographic and clinical differences in TB patients with and without DM. Using the Brazilian national surveillance system (SINAN), we compared 1,797 subjects with TB and DM with 29,275 subjects diagnosed with TB only in 2009. We performed multivariate analysis to identify factors associated with the presence of DM among TB patients. Subjects with TB - DM were older; have initial positive sputum smear test (OR = 1.42, 95% CI 1.26-1.60), and were more likely to die from TB (OR = 1.44, 95% CI 1.03-2.01). They were less likely to have been institutionalized [in prison, shelter, orphanage, psychiatric hospital (OR = 0.74, 95% CI 0.60-0.93)]; developed extra pulmonary TB (OR = 0.62, 95% CI 0.51-0.75) and to return to TB treatment after abandonment (OR = 0.66, 95% CI 0.51-0.86). Prevalence of NCD continues to rise in developing countries, especially with the rise of elderly population, the prevention and treatment of infectious diseases will be urgent. DM and TB represent a critical intersection between communicable and non-communicable diseases in these countries and the effect of DM on TB incidence and outcomes provide numerous opportunities for collaboration and management of these complex diseases in the national public health programs.

    To study the characteristics of the normal subjects with postural sway test and discuss the value of postural sway test in the diagnosis of dizzy patients. Totally 112 normal subjects, 72 patients with peripheral vertigo, and 30 patients with central vertigo were examined using a stabilometer (EAB-100, Anima Co., Japan). Items include patterns, length of locus, envelope area, deflection average center displacement, and romberg rate were recorded and compared. The postural sway was classified into the following five patterns: centripetal, forward and backward, right and left, diffuse, and multicentric. Centripetal pattern was the most prominent figure pattern in the normal subjects, while diffuse pattern was the most prominent figure pattern in the patients with central vertigo. When the normal subjects closed their eyes, age was linearly correlated with the length of locus, envelope area, rectangel area, and unit area path length (P < 0.05). Sex was not correlated to all of these parameters. The length of locus and envelope area in the patient groups were significantly increased when compared with the normal subjects (P < 0.0167). Romberg rate was not significantly different between the patients and the normal subjects. The pattern of postural sway is useful for the diagnosis of vertigo. Age is an important factor that affects the balance function. Sex seems has no influence. Visual input plays an important role in maintaining postural balance. Stabilometer is a useful tool for evaluating balance function, and postural sway test may be a valuable assistant examination.

    Full Text Available Embora a forma adulta do transtorno de déficit de atenção e hiperatividade (TDAH seja oficialmente reconhecida e respaldada cientificamente, esse diagnóstico ainda é motivo de embates entre especialistas. A maior parte do conhecimento existente ainda se deve à extrapolação dos achados de estudos com populações de crianças e adolescentes, havendo necessidade de novos estudos para validar os critérios com populações adultas. O critério de idade de início dos sintomas, o ponto de corte de seis sintomas e a necessidade de atestar comprometimento funcional em ao menos dois ambientes distintos são algumas das principais dificuldades encontradas na prática clínica para o estabelecimento do diagnóstico em adultos que freqüentemente apresentam dificuldades para resgatar informações remontando à infância. Muitos sintomas descritos são também alvos de críticas, uma vez que são claramente inapropriados para adultos. A utilização de instrumentos adaptados para adultos (como o ASRS-18, a coleta de informações com outros informantes (cônjuge e pais, por exemplo, a flexibilização da idade de início dos sintomas e uma investigação abrangente dos ambientes comprometidos pelos sintomas podem minimizar essas dificuldades.Although attention deficit hyperactivity disorder (ADHD has been officially recognized as a valid disorder into adulthood, this diagnosis is still an issue of debates between specialists. Most of the existing knowledge regarding this condition is due to the excess of findings of studies with children. As the field studies that determined DSM-IV diagnostic criteria comprised only children and adolescents, more studies with adult populations are required to validate the criteria for this population. The age of onset criteria, the cut-off of six symptoms and the requirement of impairment in at least two different settings are some of the difficulties faced by clinicians to make the diagnosis in clinical practice

    We evaluated four dengue diagnostic devices from Alere, including the SD Bioline Dengue Duo (nonstructural [NS] 1 Ag and IgG/IgM), the Panbio Dengue Duo Cassette (IgM/IgG) rapid diagnostic tests (RDTs), and the Panbio dengue IgM and IgG capture enzyme-linked immunosorbent assays (ELISAs) in a prospective, controlled, multicenter study in Peru, Venezuela, Cambodia, and the United States, using samples from 1,021 febrile individuals. Archived, well-characterized samples from an additional 135 febrile individuals from Thailand were also used. Reference testing was performed on all samples using an algorithm involving virus isolation, in-house IgM and IgG capture ELISAs, and plaque reduction neutralization tests (PRNT) to determine the infection status of the individual. The primary endpoints were the clinical sensitivities and specificities of these devices. The SD Bioline Dengue Duo had an overall sensitivity of 87.3% (95% confidence interval [CI], 84.1 to 90.2%) and specificity of 86.8% (95% CI, 83.9 to 89.3%) during the first 14 days post-symptom onset (p.s.o.). The Panbio Dengue Duo Cassette demonstrated a sensitivity of 92.1% (87.8 to 95.2%) and specificity of 62.2% (54.5 to 69.5%) during days 4 to 14 p.s.o. The Panbio IgM capture ELISA had a sensitivity of 87.6% (82.7 to 91.4%) and specificity of 88.1% (82.2 to 92.6%) during days 4 to 14 p.s.o. Finally, the Panbio IgG capture ELISA had a sensitivity of 69.6% (62.1 to 76.4%) and a specificity of 88.4% (82.6 to 92.8%) during days 4 to 14 p.s.o. for identification of secondary dengue infections.

    We evaluated four dengue diagnostic devices from Alere, including the SD Bioline Dengue Duo (nonstructural [NS] 1 Ag and IgG/IgM), the Panbio Dengue Duo Cassette (IgM/IgG) rapid diagnostic tests (RDTs), and the Panbio dengue IgM and IgG capture enzyme-linked immunosorbent assays (ELISAs) in a prospective, controlled, multicenter study in Peru, Venezuela, Cambodia, and the United States, using samples from 1,021 febrile individuals. Archived, well-characterized samples from an additional 135 febrile individuals from Thailand were also used. Reference testing was performed on all samples using an algorithm involving virus isolation, in-house IgM and IgG capture ELISAs, and plaque reduction neutralization tests (PRNT) to determine the infection status of the individual. The primary endpoints were the clinical sensitivities and specificities of these devices. The SD Bioline Dengue Duo had an overall sensitivity of 87.3% (95% confidence interval [CI], 84.1 to 90.2%) and specificity of 86.8% (95% CI, 83.9 to 89.3%) during the first 14 days post-symptom onset (p.s.o.). The Panbio Dengue Duo Cassette demonstrated a sensitivity of 92.1% (87.8 to 95.2%) and specificity of 62.2% (54.5 to 69.5%) during days 4 to 14 p.s.o.

    To evaluate the clinical and microbiological effects of a combined mechanic-antibiotic periodontal therapy in subjects that were tested positive for subgingival Actinobacillus actinomycetemcomitans (A.a.). The postoperative follow-up ranged from 12-115 months (average 39.2 months). This follow-up study analyzed the data of 53 subjects (37 females) aged from 16-59 years, who underwent systemic periodontal therapy with adjunctive systemic antibiotics between 1992-2001 and had their last re-examination including microbiological analysis done in 2003. The antibiotic regime was either amoxicillin/metronidazole or ciprofloxacine/metronidazole. During this study, A.a. was detected with two gene probe tests (IAI PadoTest 4.5 and DMDx/PathoTek) and cultivation on TSBV agar plates. The clinical situation was characterized with the help of pocket probing depths and subsequent categorization into three different groups ( or = 7 mm). After therapy, A.a. was detected with IAI PadoTest 4.5 in a magnitude between 3.0 x 10(3) up to 2.06 x 10(5) counts per specimen in 9 out of 53 subjects. Only two subjects tested positive for A.a. with the DMDx/PathoTek-assays and the agar cultivation. The clinical situation improved significantly in all subjects after systemic periodontal therapy. The treatment results remained stable during the course of the postoperative follow-up. Concerning the clinical data, no differences were found between the subjects that were tested positive and negative for A.a in the postoperative period.

    This cross-sectional study aimed to determine HPV prevalence in the oral cavity of individuals without clinically diagnosable lesions and to identify the respective HPV types. A total of 166 samples were analyzed from patients 18 years or older in the State of Pará, Brazil. Samples were collected by sterile brush scraping in the oral cavity. HPV detection used polymerase chain reaction (PCR). Infected samples were typed as HPV 6, 11, 16, 18, 31, 33, 35, 52, and 58. HPV was present in 40 samples (24.1%). Three samples (7.5%) were positive for HPV 6, five (12.5%) for HPV 18, and one (2.5%) for HPV 58.

    Recent studies demonstrate that human blood transcriptional signatures may be used to support diagnosis and clinical decisions for acute respiratory viral infections such as influenza. In this article, we propose to use a newly developed systems biology approach for time course gene expression data to identify significant dynamically response genes and dynamic gene network responses to viral infection. We illustrate the methodological pipeline by reanalyzing the time course gene expression data from a study with healthy human subjects challenged by live influenza virus. We observed clear differences in the number of significant dynamic response genes (DRGs) between the symptomatic and asymptomatic subjects and also identified DRG signatures for symptomatic subjects with influenza infection. The 505 common DRGs shared by the symptomatic subjects have high consistency with the signature genes for predicting viral infection identified in previous works. The temporal response patterns and network response features were carefully analyzed and investigated.

    Sociodemographic features, phenomenology, and psychiatric comorbidity of 30 subjects reporting pathological gambling behavior were examined. Twenty-three men and seven women were recruited by advertisement and word-of-mouth. They all scored higher than 5 points on the South Oaks Gambling Screen, indicating problematic gambling behaviors. They completed structured and semistructured assessments, including the Diagnostic Interview Schedule for DSM-III-R disorders (DIS), the Personality Diagnostic Questionnaire, Fourth Revision (PDQ-IV), and the Minnesota Impulsive Disorders Interview. The typical subject was a 44-year-old white married man with a mean income of $34,250 who visited a casino once or more weekly. All 30 subjects reported gambling more money than they intended to. Twenty subjects (67 percent) reported gambling as a current problem, and nine (30 percent) reported it as a past problem. Twenty-one subjects (70 percent) wanted to stop gambling but did not feel they could. According to DIS results, 18 subjects (60 percent) had a lifetime mood disorder, 19 (64 percent) a lifetime substance use disorder, and 12 (40 percent) a lifetime anxiety disorder. Based on the PDQ-IV, 26 subjects (87 percent) had a personality disorder, the most common being obsessive-compulsive, avoidant, schizotypal, and paranoid personality disorders. The sample also had a relatively high rate of antisocial personality disorder. Impulse control disorders were common, especially compulsive buying and compulsive sexual behavior. The results confirm that individuals with pathological gambling suffer substantial psychiatric comorbidity. They support continued inclusion of pathological gambling in the diagnostic category of impulse control disorders.

    The International Panel on the Diagnosis of Multiple Sclerosis (MS) incorporated the Barkhof/Tintore (B/T) magnetic resonance criteria into their diagnostic scheme to provide evidence of dissemination in space of central nervous system lesions, a prerequisite for diagnosing MS in patients who present with clinically isolated syndromes (CIS). Although specific for MS, the B/T criteria were criticised for their low sensitivity and relative complexity in clinical use. We used lesion characteristics at onset from 349 CIS patients in logistic regression and recursive partitioning modelling in a search for simpler and more sensitive criteria, while maintaining current specificity. The resulting models, all based on the presence of periventricular and deep white matter lesions, performed roughly in agreement with the B/T criteria, but were unable to provide higher diagnostic accuracy based on information from a single scan. Apparently, findings from contrast-enhanced and follow-up magnetic resonance scans are needed to improve the diagnostic algorithm. (orig.)

    To provide guidance to clinicians regarding the use of neoadjuvant chemotherapy and interval cytoreduction among women with stage IIIC or IV epithelial ovarian cancer. The Society of Gynecologic Oncology and the American Society of Clinical Oncology convened an Expert Panel and conducted a systematic review of the literature. Four phase III clinical trials form the primary evidence base for the recommendations. The published studies suggest that for selected women with stage IIIC or IV epithelial ovarian cancer, neoadjuvant chemotherapy and interval cytoreduction are noninferior to primary cytoreduction and adjuvant chemotherapy with respect to overall and progression-free survival and are associated with less perioperative morbidity and mortality. All women with suspected stage IIIC or IV invasive epithelial ovarian cancer should be evaluated by a gynecologic oncologist prior to initiation of therapy. The primary clinical evaluation should include a CT of the abdomen and pelvis, and chest imaging (CT preferred). Women with a high perioperative risk profile or a low likelihood of achieving cytoreduction to cancer.

    We developed an instrument to assess comprehension of informed consent information among 275 adults entering one of four ambulatory trials. At the conclusion of trial enrollment, subjects rated their understanding of the information presented and completed the Deaconess Informed Consent Comprehension Test (DICCT). Subjects completed the vocabulary subtest of the revised Weschler Adult Intelligence Scale (WAIS-R) and the reading subtest of the revised Wide Range Achievement Test (WRAT-R). The DICCT for 50 subjects was scored by 2 blinded investigators. Interrater agreement was 0.84 (df = 49, p < 0.001). To investigate the DICCT's potential validity, its scores were correlated with WAIS-R vocabulary scores (r = 0.44, df = 199, p < 0.01) and WRAT-R reading scores (r = 0.39, df = 268, p < 0.01). Understanding of consent information was rated as thorough by 70% of subjects. The mean +/- SD DICCT score was 20.4 +/- 3.9. The DICCT is a reliable instrument to assess comprehension of informed consent information. There is preliminary evidence for the scale's validity. The subjects believed that they had greater understanding of study information than was shown by the DICCT.

    2013-01-01

    Background Gonorrhoea infection is one of the most common bacterial sexually transmitted infections and an important cause of morbidity and serious complications. The objectives of this paper are: a) to describe gonorrhoea cases diagnosed in a network of 15 (out of 16) STI clinics in Spain during 2006–2010; b) to analyse differences among men who have sex with men (MSM), men who have sex exclusively with women (MSW) and women; and c) to evaluate factors associated to with HIV co-infection. Methods All gonorrhoea cases diagnosed in the network were included (25.7% of total cases notified in Spain). Data were collected by clinical staff. Descriptive/bivariate analyses were carried out stratifying by sex and transmission category; association and trends were evaluated using the chi-square test. Factors associated with HIV co-infection were estimated using a logistic regression model. Results 2385 cases were included: 55.3% among MSM, 31.3% among MSW and 13.3% among females; cases among MSM increased from 55.8% in 2006 to 62.9% in 2010 while no trends were found among the other two groups. Most MSM cases were Spaniards (72%), aged 25–34 years (46%), 49% reported previous STI and 25% concurrent STI (excluding HIV); casual partners were the commonest source of infection, and 21% of cases had rectal gonorrhoea. MSW cases did not differ from MSM by age, origin or source of infection, but frequencies of prior or concurrent STI were lower. Female cases were younger than male, were mostly foreigners (58%), and 41% were sex workers; concurrent STI (other than HIV) were diagnosed in 30%; 20.4% had symptoms (72.5% and 89.2% in MSM and MSW), and pharyngeal location was present in 30%. HIV co-infection was highest in MSM (20.9%). Co-infection was associated with age > 35 years, low educational level, being Western European or Latin-American, being MSM, having previous or concurrent STI and reporting contact with an HIV-infected partner; it was inversely associated with

    This cross-sectional study aimed to identify nursing diagnoses in critical patients at risk of developing pressure ulcer. It was carried out at an Intensive Care Unit in Fortaleza-CE, Brazil, using an intentional sample of thirteen subjects at risk of pressure ulcer, evaluated according to the Waterlow scale. In total, 45 nursing diagnoses were evidenced, seventeen of which were clinically significant for the development of pressure ulcer. The frequency levels for nine of these nursing diagnoses were ≥ 80%, mainly: Impaired skin integrity (100%), Impaired walking (87%), Impaired swallowing (80%), Impaired bed mobility (80%) and Impaired gas exchange (80%). The knowledge of those nursing diagnoses is important in detecting the effects and clinical basis of skin lesions.

    Full Text Available Over past decade, the Iowa gambling task (IGT has been utilized to test various decision deficits induced by neurological damage or psychiatric disorders. The IGT has recently been standardized for identifying 13 different neuropsychological disorders. Neuropsychological patients choose bad decks frequently, and normal subjects prefer good EV decks. However, the IGT has several validity and reliability problems. Some research groups have pointed out that the validity of IGT is influenced by the personality and emotional state of subjects. Additionally, several other studies have proposed that the prominent deck B phenomenon (PDB phenomenon – that is, normal subjects preferring bad deck B – may be the most serious problem confronting IGT validity. Specifically, deck B offers a high frequency of gains but negative EV. In the standard IGT administration, choice behavior can be understood with reference to gain-loss frequency (GLF rather than inferred future consequences (EV, the basic assumption of IGT. Furthermore, using two different criteria (basic assumption vs. professional norm results in significantly different classification results. Therefore, we recruited 72 normal subjects to test the validity and reliability of IGT. Each subject performed three runs of the computer-based clinical IGT version. The PDB phenomenon has been observed to a significant degree in the first and second stages of the clinical IGT version. Obviously, validity, reliability and the practice effect were unstable between two given stages. The present form of the clinical IGT version has only one stage, so its use should be reconsidered for examining normal decision makers; results from patient groups must also be interpreted with great care. GLF could be the main factor to be considered in establishing the constructional validity and reliability of the clinical IGT version.

    Few studies of the clergy have examined emotional well-being using normed measures. This study examined subjective well-being among 1,581 non-retired Episcopal priests. Subjective well-being was measured with the Positive and Negative Affect Schedule (Watson, Clark, & Tellegen, 1988) and the Satisfaction with Life Scale (Diener, Emmons, Larsen, & Griffin, 1985). Predictors of subjective well-being were measured with the Dispositional Hope Scale (Snyder et al., 1991) and scales of personal practices, social support, congregational dynamics, fit, and economic satisfaction. Participants reported more positive affect (Hedges's g = 1.19), more negative affect (Hedges's g = 0.61) and more satisfaction with life (Hedges's g = 0.73) than nonclinical norms. Hope agency was the strongest predictor for positive affect and satisfaction with life; stress was the strongest predictor for negative affect and partially mediated the effect of congregational dynamics and fit on this outcome. Results suggest that prevention programs must focus on all aspects of subjective well-being and consider the direct effects of different levels of the ecosystem to be effective.

    Darunavir 800 mg once daily (QD) is indicated for HIV-1-infected treatment-naïve and treatment-experienced (without darunavir resistance-associated mutations [RAMs]) individuals, and has been evaluated in phase 2/3 studies with durations between 48 and 192 weeks. To summarize the development (or identification) of post-baseline resistance (RAMs and antiretroviral phenotypic susceptibility) among subjects receiving darunavir QD dosing. Seven phase 2/3 studies with available genotypes/phenotypes for subjects treated with ritonavir- or cobicistat-boosted darunavir 800 mg QD regimens were assessed: ARTEMIS (NCT00258557; n = 343), GS-US-299-0102 (NCT01565850; n = 153), GS-US-216-0130 (NCT01440569; n = 313), ODIN (NCT00524368; n = 294), INROADS (NCT01199939; n = 54), MONET (NCT00458302; n = 256), and PROTEA (NCT01448707; n = 273). Genotypic analyses were conducted at baseline (except switch studies enrolling virologically suppressed subjects [MONET, PROTEA]). Criteria for post-baseline resistance testing and evaluation of the development (or identification [switch studies]) of RAMs (respective IAS-USA mutations) varied slightly across studies. Among 1686 subjects treated with darunavir 800 mg QD regimens, 184 had protocol-defined virologic failure; 182 had post-baseline genotypes analyzed. Overall, 4/1686 (0.2%) developed (or had identified [switch studies]) primary protease inhibitor and/or darunavir RAMs (ARTEMIS, n = 1; GS-US-216-0130, n = 1; ODIN, n = 1; MONET, n = 1). Only 1/1686 (1%) subject lost darunavir phenotypic susceptibility (ODIN; possibly related to prior ritonavir-boosted lopinavir virologic failure). Among 1103 subjects using a nucleos(t)ide reverse transcriptase inhibitor (N[t]RTI) backbone, 10 (0.9%) developed ≥ 1 N(t)RTI RAM (8 had the emtricitabine RAM M184I/V). Darunavir has a high genetic barrier to resistance. Across a diverse population of HIV-1-infected subjects treated with darunavir 800 mg QD regimens, the

    Despite lymphocytic or autoimmune infundibuloneurohypophysitis (INH) is an increasingly recognized aetiology in children with central diabetes insipidus (CDI); clinical data on epidemiology (clinical evolution, predisposing factors, complications), diagnosis and management of this entity are limited and mostly based on published case reports. The aim of this study was to gain a broader insight in the natural history of this disease by analysing the clinical presentation, radiological pituitary stalk changes, associated autoimmunity and hormonal deficiencies in children with CDI and a self-limiting or transient stalk thickening (ST), diagnosed as autoimmune infundibuloneurohypophysitis, during the last 15 years in four Belgian university hospitals. The medical files of nine CDI patients with a ST at initial presentation and no signs of Langerhans cell histiocytosis or germinoma at presentation and/or during follow-up of more than 1.5 years were reviewed. Age at presentation ranged from 3 to 14 years. Two patients had a positive family history of autoimmunity. Three children presented with associated growth failure, two with nausea and one with long-standing headache. Median maximal diameter of the stalk was 4.6 mm (2.7-10 mm). Four patients had extra-pituitary brain anomalies, such as cysts. One patient had central hypothyroidism, and another had a partial growth hormone deficiency at diagnosis. Within a mean follow-up of 5.4 (1.5-15) years, stalk thickening remained unchanged in two patients, regressed in one and normalized in six children. CDI remained in all, while additional pituitary hormone deficiencies developed in only one patient. In this series of children INH with CDI as initial presentation, CDI was permanent and infrequently associated with anterior pituitary hormone deficiencies, despite a frequent association with nonstalk cerebral lesions. © 2017 The Authors.

    The utility of urine and serum hepcidin measurements in the clinic depends on their reproducibility. We sought to expand our previous work on the within-subject variability and between-subject variability of this novel iron parameter in the serum and urine of 24 healthy controls by time-of-flight mass spectrometry at four different time points during the day. A linear mixed model for repeated data was used to distinguish three components of the total variability in the measurements: within-day/within-subject variability, between-subject variability, and additional residual or (pre)analytical variability. Differences in diurnal hepcidin patterns were observed between urine and serum. Urine levels remained similar during the course of the morning and increased significantly during the afternoon, whereas serum levels increased significantly throughout both the morning and afternoon. Furthermore, in serum the (pre)analytical variability (28.6%) was smaller than the between-subject (48.1%) and within-day/within-subject variability (30.3%) compared with urine variability (97.2% vs. 67.7 and 77.3%, respectively). High serum ferritin levels were associated with higher serum hepcidin levels but not with urine levels. Transferrin saturation did not correlate with hepcidin levels. To minimize variability, we recommend (i) standardizing for sampling time and (ii) measuring serum hepcidin levels.

    Full Text Available Abstract Background Usher syndrome (USH is an autosomal recessive genetically heterogeneous disorder with congenital sensorineural hearing impairment and retinitis pigmentosa (RP. We have identified a consanguineous Lebanese family with two affected members displaying progressive hearing loss, RP and cataracts, therefore clinically diagnosed as USH type 3 (USH3. Our study was aimed at the identification of the causative mutation in this USH3-like family. Methods Candidate loci were identified using genomewide SNP-array-based homozygosity mapping followed by targeted enrichment and next-generation sequencing. Results Using a capture array targeting the three identified homozygosity-by-descent regions on chromosomes 1q43-q44, 20p13-p12.2 and 20p11.23-q12, we identified a homozygous nonsense mutation, p.Arg65X, in ABHD12 segregating with the phenotype. Conclusion Mutations of ABHD12, an enzyme hydrolyzing an endocannabinoid lipid transmitter, cause PHARC (polyneuropathy, hearing loss, ataxia, retinitis pigmentosa, and early-onset cataract. After the identification of the ABHD12 mutation in this family, one patient underwent neurological examination which revealed ataxia, but no polyneuropathy. ABHD12 is not known to be related to the USH protein interactome. The phenotype of our patient represents a variant of PHARC, an entity that should be taken into account as differential diagnosis for USH3. Our study demonstrates the potential of comprehensive genetic analysis for improving the clinical diagnosis.

    Cyanotic CHD comprises up to 25% of cases of all causes of CHD. There is lack of data about the present spectrum of congenital cyanotic heart disease in the paediatric age group. The present study was undertaken to determine the spectrum of patients with congenital cyanotic heart disease in the paediatric age group in tertiary paediatric cardiac care clinic. Prospective observational study. Paediatric cardiac clinic of a tertiary cardiac care centre. All children aged 0-18 years with suspected cyanotic CHD were provisionally included in this study. They underwent a thorough echocardiographic evaluation, and those patients who had definitive diagnosis of congenital cyanotic heart disease were included for final analysis. A total of 119 children met the inclusion criteria. Tetralogy of Fallot and its variant were the most common congenital cyanotic heart disease with proportion of about 44%. Other common malformations were double outlet right ventricle (14%), pulmonary atresia with ventricular septal defect (8%), total anomalous pulmonary venous connection (7%), d-transposition of the great arteries (9%), tricuspid valve anomalies--tricuspid atresia and Ebstein's anomaly--hypoplastic left-heart syndrome, truncus arteriosus, and complex CHD such as single ventricle. Tetralogy of Fallot and its variants were the most common cyanotic heart disease diagnosed in our patients. As there were a significant proportion of cases with complex cyanotic CHD, paediatric cardiologists should be familiar with the diagnosis and management of all these complex congenital malformations of the heart.

Materials and Methods: The cases with SD were evaluated retrospectively. Hematological, serological, biochemical laboratory tests and imaging technics were used for diagnosis. Results: Of 55 cases aged ranging between 25 to 79, 33 (59% were female. The cases with tuberculous SD (TBSD, brucellar SD (BSD and pyogenic SD (PSD were found in 24 (43%, 12 (21% and in 19 (34% patients.Erytrocyte sedimentation rate, increased C-reactive protein, and leucocytosis were present in 51 (91%, 22 (39% and 8 (14% cases. The number of the cases with history of previous surgery or trauma was 14 (25%. Diagnosis of TBSD was established by acid fast bacilli positiveness and Löwenstein Jensen culture positiveness, in two and seven patients, respectively. While all 12 cases with BSD had positive standard tube aglutination test, only 3 (25% had hemoculture positivity. In PSDs, diagnosis was confirmed with culture positivity in 9 of 19 cases.Of the cases in our study, 89% responded to medical treatment while three required surgery and three died (5.5% and 5.5%, respectively. Conclusion: SD may develop secondary to infections or following spinal surgical procedures and traumas. Also, the importance of endemicity should be kept in mind, beside the helpful diagnostic findings while treatment regulation.

    Limb-girdle muscular dystrophy type 2C (LGMD2C) is an autosomal recessive muscle dystrophy that resembles Duchenne muscular dystrophy (DMD). Although DMD is known to affect one in every 3500 males regardless of race, a widespread founder mutation causing LGMD2C has been described in North Africa. However, the incidence of LGMD2C in Japanese has been unknown because the genetic background remains uncharacterized in many patients clinically diagnosed with DMD. We enrolled 324 patients referred to the Kobe University Hospital with suspected DMD. Mutations in the dystrophin or the SGCG genes were analyzed using not only genomic DNA but also cDNA. In 322 of the 324 patients, responsible mutations in the dystrophin were successfully revealed, confirming DMD diagnosis. The remaining two patients had normal dystrophin expression but absence of gamma-sarcoglycan in skeletal muscle. Mutation analysis of the SGCG gene revealed homozygous deletion of exon 6 in one patient, while the other had a novel single nucleotide insertion in exon 7 in one allele and deletion of exon 6 in the other allele. These mutations created a stop codon that led to a gamma-sarcoglycan deficiency, and we therefore diagnosed these two patients as having LGMD2C. Thus, the relative incidence of LGMD2C among Japanese DMD-like patients can be calculated as 1 in 161 patients suspected to have DMD (2 of 324 patients = 0.6%). Taking into consideration the DMD incidence for the overall population (1/3,500 males), the incidence of LGMD2C can be estimated as 1 per 560,000 or 1.8 per million. To the best of our knowledge, this is the first study to demonstrate a low incidence of LGMD2C in the Japanese population.

    Although numerous perioperative samples and culture media are required to diagnose prosthetic joint infection (PJI), their exact number and types have not yet been definitely determined with a high level of proof. We conducted a prospective multicenter study to determine the minimal number of samples and culture media required for accurate diagnosis of PJI. Over a 2-year period, consecutive patients with clinical signs suggesting PJI were included, with five perioperative samples per patient. The bacteriological and PJI diagnosis criteria were assessed using a random selection of two, three, or four samples and compared with those obtained using the recommended five samples (references guidelines). The results obtained with two or three culture media were then compared with those obtained with five culture media for both criteria. The times-to-positivity of the different culture media were calculated. PJI was confirmed in 215/264 suspected cases, with a bacteriological criterion in 192 (89%). The PJI was monomicrobial (85%) or polymicrobial (15%). Percentages of agreement of 98.1% and 99.7%, respectively, for the bacteriological criterion and confirmed PJI diagnosis were obtained when four perioperative samples were considered. The highest percentages of agreement were obtained with the association of three culture media, a blood culture bottle, a chocolate agar plate, and Schaedler broth, incubated for 5, 7, and 14 days, respectively. This new procedure leads to significant cost saving. Our prospective multicenter study showed that four samples seeded on three culture media are sufficient for diagnosing PJI.

    Manifestations of mold allergy are classically associated with inhalation of mold spores leading to symptoms of asthma and other respiratory illnesses. It is largely unknown, however, whether ingestion of aeroallergenic molds, mold spores, or other fungi found in food can also elicit hypersensitivity reactions in mold-sensitive individuals. The aim of this study was to evaluate the association between exposure to molds by oral challenge and elicitation of symptoms in mold- versus nonmold-sensitive individuals. Thirty-four adult atopic subjects were randomized into mold-sensitive groups based on skin test reactivity by skin percutaneous testing (SPT) and/or intradermal (ID) testing to a mixed mold (MM) extract preparation. All subjects underwent a single-blinded, placebo-controlled food challenge to the MM preparation. A modified scoring system was used to grade the clinical severity of symptoms elicited by challenge. All subjects tolerated challenges to the maximal oral mold dose concentration. However, higher symptom scores after challenge were found in mold-sensitive subjects compared with nonmold-sensitive subjects (p = 0.01). When mold-sensitive subjects were compared based on SPT and/or ID reactivity, higher symptom scores and lower symptom-eliciting concentrations of mold were associated with the SPT reactive subgroup compared with the subgroup with ID reactivity alone. In summary, based on our challenge results and scoring model, mold-sensitive subjects compared with nonmold-sensitive subjects experienced cumulatively higher symptom scores after oral challenge to an MM extract preparation. Future studies are warranted to confirm whether ingestion of aeroallergenic molds in food may be another contributor to symptoms in mold-sensitive individuals.

    A significant comorbidity between attention-deficit/hyperactivity disorder (ADHD) and affective disorders has been consistently reported in adults. Less data regarding the role of personality traits and the influence of ADHD co-occurrence on clinical characteristics and outcome of mood disorders are currently available. One hundred and six remitted major depressed, 102 euthymic bipolar subjects, and 120 healthy controls, homogeneous with respect to demographic characteristics, were included in the study. ADHD diagnosis was based on DSM-IV-TR criteria. Childhood and adult ADHD features were measured with the Wender Utah Rating Scale, the Adult ADHD Self-rating Scale, and the Brown Attention-Deficit Disorder Scale. The Revised NEO Personality Inventory was also administered to the clinical groups, in order to investigate personality dimensions. The occurrence of adult ADHD in subjects with bipolar disorders (BD) or major depressive disorder (MDD) was 15.7 and 7.5 %, respectively, compared to 3.3 % in healthy controls (HC). Significant associations (p < .001) between personality traits (neuroticism, conscientiousness, and extraversion) and ADHD features were observed. Logistic regression analysis of all clinical subjects (n = 208) showed that those with lower levels of neuroticism (OR = 1.031; p = .025) had a lower frequency of ADHD comorbidity. The present study emphasizes the close relationship between affective disorders, especially BD, and ADHD in adults. Our findings support the need to assess subjects with mood disorders in the clinical setting for possible coexisting ADHD and to further investigate personality traits to better understand the etiology of affective disorders and ADHD co-occurrence.

    Patients with pain are more reactive to various types of sensations, not limited to pain alone. A potential useful instrument to assess reactivity is the Kohn Reactivity Scale (KRS). This study examines the psychometric characteristics of the KRS-Dutch version and its ability to differentiate between subjects with and without pain. Internal consistency, convergent validity, and test-retest reliability of the Dutch translation of the KRS were assessed in 321 pain-free control subjects and different subgroups of this sample. Subsequently, reactivity scores were compared between the pain-free subjects and 291 pain patients who were referred to a pain clinic for treatment. Reliability analyses indicated good internal consistency (α ≥ 0.77) and high test-retest reliability (intraclass correlation = 0.95) of the KRS in the control subjects. Validity analyses yielded positive correlations of the KRS with related constructs like pain vigilance and awareness (r = 0.37), symptom severity (r = 0.29), and the personality characteristic neuroticism (r = 0.20). Pain patients had overall significantly higher KRS scores than the pain-free subjects indicating increased reactivity, particularly for the patients with medically unexplained pain. These findings indicate that the KRS is a useful instrument to screen for reactivity in pain patients, which may be of particular relevance for those suffering from medically unexplained pain. © 2012 The Authors Pain Practice © 2012 World Institute of Pain.

    In hospitalized patients, lack of appetite, i.e., disease-associated anorexia, is the main factor determining insufficient food intake and weight loss, which in turn increase morbidity and mortality. Controversies exist on which tool should be preferred when diagnosing anorexia. Aim of the study was to evaluate in hospitalized medical patients, the performance of 4 different tools [i.e., self-assessment of appetite, FAACT-ESPEN score, visual analog scale (VAS), and the Anorexia Questionnaire (AQ)] in assessing disease-associated anorexia and predicting nutritional and clinical variables. Hospitalized patients consecutively admitted to the Internal Medicine ward at our institution were considered. After informed consent was obtained, patients were asked to self-assess their appetite vs the previous month. The VAS, the FAACT-ESPEN score and the Anorexia Questionnaire were also submitted. Food intake immediately following the interview was recorded. Nutritional (i.e., body weight, height), functional (i.e., handgrip strength) and clinical variables (i.e., length of stay) were registered upon admission and before discharge. We studied 105 patients (74M:31F; 66.2 ± 16.3 yrs). The prevalence of anorexia as assessed by patients' self assessment, FAACT-ESPEN score, and the Anorexia Questionnaire was 23%, 10% and 48%, respectively. VAS did not show any correlation with food intake. Anorexic patients as identified by the self assessment of appetite showed reduced food intake and weaker handgrip strength than non-anorexic. The FAACT-ESPEN score correlated with body weight, food intake and handgrip strength, but was not related with length of stay. Anorexic patients as identified by the Anorexia Questionnaire showed reduced food intake, lower body weight, weaker handgrip strength and longer hospital stay than non-anorexic patients. The prevalence of anorexia significantly varies according to the diagnostic tool used. Except for VAS, all the tested tools identify patients with

    Full Text Available This clinical practice guideline formulates recommendations for health care providers regarding the diagnosis, evaluation, and treatment of children, ages 1 to 21 years, with uncomplicated acute, subacute, and recurrent acute bacterial sinusitis. Three specific issues were considered: 1 evidence for the efficacy of various antibiotics in children; 2 evidence for the efficacy of various ancillary, nonantibiotic regimens; and 3 the diagnostic accuracy and concordance of clinical symptoms, radiography (and other imaging methods, and sinus aspiration.It is recommended that the diagnosis of acute bacterial sinusitis be based on clinical criteria in children ≤6 years of age who present with upper respiratory symptoms that are either persistent or severe. Although controversial, imaging studies may be necessary to confirm a diagnosis of acute bacterial sinusitis in children >6 years of age. Computed tomography scans of the paranasal sinuses should be reserved for children who present with complications of acute bacterial sinusitis or who have very persistent or recurrent infections and are not responsive to medical management.There were only 5 controlled randomized trials and 8 case series on antimicrobial therapy for acute bacterial sinusitis in children. However, these data, plus data derived from the study of adults with acute bacterial sinusitis, support the recommendation that acute bacterial sinusitis be treated with antimicrobial therapy to achieve a more rapid clinical cure. Children with complications or suspected complications of acute bacterial sinusitis should be treated promptly and aggressively with antibiotics and, when appropriate, drainage. Based on controversial and limited data, no recommendations are made about the use of prophylactic antimicrobials, ancillary therapies, or complementary/alternative medicine for prevention and treatment of acute bacterial sinusitis.Key words: sinusitis, treatment, management, children.

    The purpose of the present cross-sectional study was to assess the extent of agreement between clinical and self-assessed periodontal health status among patients visiting the outpatient department of M.S. Ramaiah Dental College, Bangalore, India. The study population included 216 patients aged between 20 and 44 years who attended the outpatient department of the M.S. Ramaiah Dental College, Bangalore. The study population was subjected to a self-administered questionnaire (questions regarding bleeding gums, deposits on teeth, receding gums, swelling of gums, loose teeth), which was followed by periodontal examination. The clinical examination included an assessment of the periodontal condition, using the criteria of Loe and Silness Gingival Index, the Community Periodontal Index, and Mobility, respectively. The present study showed that the perceived periodontal health status was low and the discrepancy between the subjectively and objectively assessed needs was very distinct. The awareness of the periodontal problems has been reported to increase with increasing severity of the disease due to the destructive changes that set in.

    Health-related quality of life tools that better reflect the unique subjective perception of heart failure (HF) are needed for patients with this disorder. The aim of this study was to explore whether subjective satisfaction of HF patients about daily life may provide additional prognostic information with respect to clinical cardiological data. One hundred and seventy-eight patients (age 51 ± 9 years) with moderate to severe HF [New York Heart Association (NYHA) class 2.0 ± 0.7; left ventricular ejection fraction (LVEF) 29 ± 8%] in stable clinical condition underwent a standard clinical evaluation and compiled the Satisfaction Profile (SAT-P) questionnaire focusing on subjective satisfaction with daily life. Cox regression analysis was used to assess whether SAT-P factors (psychological functioning, physical functioning, work, sleep/eating/leisure, social functioning) had any prognostic value. Forty-six cardiac deaths occurred during a median of 30 months. Patients who died had higher NYHA class, more depressed left ventricular function, reduced systolic blood pressure (SBP), increased heart rate (HR), and worse biochemistry (all p patients who died (p = 0.003). Using the best subset selection procedure, resistance to physical fatigue (RPF) was selected from among the items of the PF factor. RPF showed independent predictive value when entered into a prognostic model including NYHA class, LVEF, SBP, and HR with an adjusted hazard ratio of 0.86 per 10 units increase (95% CI 0.75-0.98, p = 0.02). Patients' dissatisfaction with physical functioning is associated with reduced long-term survival, after adjustment for known risk factors in HF. Given its user-friendly structure, simplicity, and significant prognostic value, the RPF score may represent a useful instrument in clinical practice.

    Recent studies have suggested that pioglitazone exerts anti-oxidant properties which may countervail oxidative stress (OS). We aimed to elucidate the effects of pioglitazone on OS modulation and to compare its effects with metformin. Data from the randomized clinical trial (registration no.NCT01521624) were used. Newly diagnosed type 2 diabetes patients were assigned to pioglitazone 30mg daily (n=30), metformin 1000mg daily (n=50), or no medication (n=49). Recommendations for exercise and dietary modifications were provided for three groups. Serum concentrations of advanced oxidation protein products(AOPP), advanced glycation end products(AGE), ferritin reducing ability of plasma(FRAP), and enzymatic activities of paraoxonase(PON), lecithin-cholesterol asyltransferase(LCAT), and lipoprotein lipase(LPL) were measured at baseline and after three months. In comparison with no medication, pioglitazone proved to be superior in OS amelioration (pmetformin, both medications were equally effective in decrement of AOPP and AGE, along with increment of PON (p=0.688, 0.140, and 0.273, respectively). FRAP concentrations increased significantly with metformin (p=0.012). On the other hand, pioglitazone yielded better efficacy in restoration of LCAT and LPL enzymatic activities (p=0.037, and metformin, three months treatment with Pioglitazone is beneficial in terms of OS alleviation and anti-oxidant capacity restoration.

    Transient myeloproliferative disorder (TMD), restricted to newborns with trisomy 21, is a megakaryocytic leukemia that although lethal in some is distinguished by its spontaneous resolution. Later development of acute myeloid leukemia (AML) occurs in some. Prospective enrollment (n = 135) elucidated the natural history in Down syndrome (DS) patients diagnosed with TMD via the use of uniform monitoring and intervention guidelines. Prevalent at diagnosis were leukocytosis, peripheral blast exceeding marrow blast percentage, and hepatomegaly. Among those with life-threatening symptoms, most (n = 29/38; 76%) received intervention therapy until symptoms abated and then were monitored similarly. Organomegaly with cardiopulmonary compromise most frequently led to intervention (43%). Death occurred in 21% but only 10% were attributable to TMD (intervention vs observation patients: 13/14 vs 1/15 because of TMD). Among those solely observed, peripheral blasts and all other TMD symptoms cleared at a median of 36 and 49 days from diagnosis, respectively. On the basis of the diagnostic clinical findings of hepatomegaly with or without life-threatening symptoms, 3 groups were identified with differing survival: low risk with neither finding (38%), intermediate risk with hepatomegaly alone (40%), and high risk with both (21%; overall survival: 92% ± 8%, 77% ± 12%, and 51% ± 19%, respectively; P ≤ .001). Among all, AML subsequently occurred in 16% at a median of 441 days (range, 118-1085 days). The trial is registered at http://www.clinicaltrials.gov as NCT00003593.

    Tipifarnib (T) exhibits modest activity in elderly adults with newly diagnosed acute myelogenous leukemia (AML). Based on preclinical synergy, a phase 1 trial of T plus etoposide (E) yielded 25% complete remission (CR). We selected 2 comparable dose levels for a randomized phase 2 trial in 84 adults (age range, 70-90 years; median, 76 years) who were not candidates for conventional chemotherapy. Arm A (T 600 mg twice a day × 14 days, E 100 mg days 1-3 and 8-10) and arm B (T 400 mg twice a day × 14 days, E 200 mg days 1-3 and 8-10) yielded similar CR, but arm B had greater toxicity. Total CR was 25%, day 30 death rate 7%. A 2-gene signature of high RASGRP1 and low aprataxin (APTX) expression previously predicted for T response. Assays using blasts from a subset of 40 patients treated with T plus E on this study showed that AMLs with a RASGRP1/APTX ratio of more than 5.2 had a 78% CR rate and negative predictive value 87%. This ratio did not correlate with outcome in 41 patients treated with conventional chemotherapies. The next T-based clinical trials will test the ability of the 2-gene signature to enrich for T responders prospectively. This study is registered at www.clinicaltrials.gov as #NCT00602771.

    In 2013 the World Health Organization deemed hypertension as a global crisis as it is the leading risk factor attributed to global mortality. Therefore, there is a great need for effective alternative treatment strategies to combat a condition that affects 40% of adults worldwide. Recently, the FlaxPAD Trial observed a significant reduction in systolic and diastolic blood pressure in hypertensive patients with peripheral arterial disease that consumed 30 g of milled flaxseed per day for one year. However, these patients were already on anti-hypertensive medication. Therefore, there is a need to assess if dietary flaxseed can effectively reduce blood pressure in the absence of peripheral arterial disease and anti-hypertensive medication in newly diagnosed hypertensive patients. The HYPERFlax Trial is a parallel, superiority, phase II/III, randomized, double-blinded, controlled clinical trial. St. Boniface Hospital and the Health Sciences Centre of Winnipeg, Canada, will recruit 100 participants newly diagnosed with stage 1 hypertension who have yet to be administered anti-hypertensive medication. Participants will be randomly allocated with a 1:1 ratio into a flaxseed or control group and provided food products to consume daily for six months. At baseline, two, four, and six months, participant assessments will include the primary outcome measure, averaged automated blood pressure, and secondary measures: 24-hour food recall, international physical activity questionnaire, anthropometrics, and blood and urine sampling for biochemical analysis. Plasma will be assessed for lipids, metabolomics profiling, and molecules that regulate vascular tone. Urine will be collected for metabolomics profiling. With an estimated dropout rate of 20%, the trial will have a power of 0.80 to detect differences between groups and across time, out of an effect size of 0.7 (SD) at an α level of 0.05. This trial will determine if dietary flaxseed is efficacious over six months as an anti

    Genetic test results have medical implications beyond the patient that extend to biological family members. We examined psychosocial and clinical factors associated with communication of genetic test results within families. Women (N = 1080) diagnosed with breast cancer at age 40 or younger completed an online survey; 920 women that reported prior cancer genetic testing were included in analysis. We examined the proportion of immediate family members to whom they communicated genetic test results, and built multivariable regression models to examine clinical and psychosocial variables associated with the proportion score. Participants were most likely to communicate test results to their mother (83 %) and least likely to their son (45 %). Participants who carried a BRCA mutation (OR = 1.34; 95 % CI = 1.06, 1.70), had higher interest in genomic information (OR = 1.55; 95 % CI = 1.26, 1.91) and lower genetic worry (OR = 0.91; 95 % CI = 0.86, 0.96) communicated genetic test results to a greater proportion of their immediate family members. Participants with a BRCA1/2 mutation shared their genetic test results with more male family members (OR = 1.72; 95 % CI = 1.02, 2.89). Our findings suggest that patients with high worry about genetic risks, low interest in genomic information, or receive a negative genetic test result will likely need additional support to encourage family communication.

    To assess the utility of acute electroencephalography (EEG) performed in the emergency room (ER) and its impact on subsequent management of patients with new-onset seizures. Adults who recover fully in the ER following suspected isolated new-onset seizures are usually discharged to the neurology clinic for further review. An EEG at that stage may be normal. We sought to assess the feasibility and yield of early EEG in the ER setting, its impact on management. A prospective study from January 2008 to January 2011 of patients diagnosed by ER physicians with uncomplicated suspected first episodes of unprovoked convulsive seizures. All patients underwent routine 30-min EEG in the ER prior to discharge and specialist review was arranged in the epilepsy clinic within 2 weeks of presentation. Management decisions were at the discretion of the treating neurologist. Seizure recurrence was assessed during a follow up period between 9 months and 3 years. 136 patients were included in the study (92 males). Mean age was 32 years (range 16-73). Forty had abnormal EEGs: 16 focal epileptiform discharges, 12 focal slowing, 10 generalized spike-wave discharges and 2 generalized slowing. Using multivariate analysis, those with abnormal EEG (51% vs 11%, p = 0.003) and abnormal MRI (53% vs 28%, p EEG had a high diagnostic yield. Abnormal EEG and abnormal MRI significantly contributed to decision-making regarding treatment at specialist review. Abnormal MRI was associated with significantly higher risks of subsequent seizures. Copyright © 2015 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Cancer affects older adults disproportionately. The disease is often difficult to diagnose and treat due to co-morbidities and performance status, and patients tend to discontinue chemotherapy prematurely. There are no systemic studies of the reasons and factors that create a higher withdrawal rate in older acute leukemia patients. This study tried to understand the initial characteristics, blood counts and bone marrow measurements in older acute leukemia patients by comparing them with a younger group to provide information and assistance in early clinical diagnosis, treatment and reasons for treatment withdrawal. Methods Using retrospective medical record reviews, we examined clinical characteristics and chemotherapy completion status in the patients of two groups (age ≥ 60, n = 183 and age Results There were no statistical differences in initial presenting symptoms of fatigue (67.2% vs. 57.9%, P>0.05 and pallor (53% vs. 59.6%, P>0.05 between the two groups, but older patients demonstrated more underlying diseases including lung infections (25.7%, P = P = 0.007, and hypertension (20.8%, P =2 = 6.202, P = 0.013. The percentage of patients age 60 and older who prematurely discontinued chemotherapy (50.3%, mainly due to the influences of traditional Chinese concept of critical illness, financial difficulties, and intolerance to adverse reactions to chemotherapy, was significantly higher than that of younger patients (37.7% (χ2 = 5.866, P = 0.015. Conclusions A comprehensive approach to diagnosis, treatment selection, and toxicity management, and implementing strategies to enhance treatment compliance may improve outcomes in older adults with acute leukemia.

    Recently, we reported our clinical experiences of boron neutron capture therapy (BNCT) for the newly diagnosed glioblastoma. The major differences of our protocol from the other past studies were simultaneous use of both sodium borocapate and boronophenylalanine, and combination with fractionated X-ray irradiation. These results showed the efficacy of combination therapy with external beam X-ray irradiation and BNCT. For our future study, we planned the multi-centric phase II clinical study for newly diagnosed glioblastoma patients in Japan (OSAKA-TRIBRAIN0902, NCT00974987).

  14. A better alternative to stratified permuted block design for subject randomization in clinical trials.

    Stratified permuted block randomization has been the dominant covariate-adaptive randomization procedure in clinical trials for several decades. Its high probability of deterministic assignment and low capacity of covariate balancing have been well recognized. The popularity of this sub-optimal method is largely due to its simplicity in implementation and the lack of better alternatives. Proposed in this paper is a two-stage covariate-adaptive randomization procedure that uses the block urn design or the big stick design in stage one to restrict the treatment imbalance within each covariate stratum, and uses the biased-coin minimization method in stage two to control imbalances in the distribution of additional covariates that are not included in the stratification algorithm. Analytical and simulation results show that the new randomization procedure significantly reduces the probability of deterministic assignments, and improve the covariate balancing capacity when compared to the traditional stratified permuted block randomization.

    Subjects with autosomal dominant polycystic kidney disease (ADPKD) who were taking tolvaptan experienced aminotransferase elevations more frequently than those on placebo in the TEMPO 3:4 (Tolvaptan Efficacy and Safety in Management of Autosomal Dominant Polycystic Kidney Disease and its Outcomes) clinical trial. An independent, blinded, expert Hepatic Adjudication Committee re-examined data from TEMPO 3:4 and its open-label extension TEMPO 4:4, as well as from long-term (>14 months) non-ADPKD tolvaptan trials, using the 5-point Drug-Induced Liver Injury Network classification. In TEMPO 3:4, 1445 subjects were randomized 2:1 (tolvaptan vs. placebo) and 1441 had post-baseline assessments of hepatic injury. Sixteen patients on tolvaptan and one on placebo had significant aminotransferase elevations judged to be at least probably related to study drug. No association with dose or systemic exposure was found. Two of 957 subjects taking tolvaptan (0.2 %) and zero of 484 taking placebo met the definition of a Hy's Law case. One additional Hy's Law case was identified in a TEMPO 4:4 subject who had received placebo in the lead study. The onset of a hepatocellular injury occurred between 3 and 18 months after starting tolvaptan, with gradual resolution over the subsequent 1-4 months. None of the events were associated with liver failure or chronic liver injury/dysfunction. No imbalance in hepatic events was observed between tolvaptan and placebo in lower-dose clinical trials of patients with hyponatremia, heart failure, or cirrhosis. Although hepatocellular injury following long-term tolvaptan treatment in ADPKD subjects was infrequent and reversible, the potential for serious irreversible injury exists. Regular monitoring of transaminase levels is warranted in this patient population.

    To investigate the serum myeloperoxidase (MPO) activity and serum paraoxonase-1 (PON-1) activity in patients with silicosis and observation subjects and their clinical significance. Seventy-two patients with silicosis (stage I: 30 cases, stage II: 22 cases, stage III: 20 cases) and 37 observation subjects were selected as a case group, and 110 healthy men were selected as a control group. Serum MPO activity was measured by double-antibody sandwich enzyme-linked immunosorbent assay, and serum PON-1 activity was measured by chemical spectrophotometry. Serum MPO activity was significantly higher in the case group than in the control group [(102.1 ± 15.7) U/L vs. (62.4 ± 11.4) U/L, P silicosis than in the observation subjects [(91.3 ± 13.5) U/L, (85.7 ± 14.4) U/L, and (88.6 ± 14.5) U/L vs. (128.4 ± 16.4) U/L, P silicosis increased; serum PON-1 activity was significantly lower in the patients with stages II and III silicosis than in the observation subjects and the patients with stage I silicosis [(70.4 ± 11.4) U/ml and (67.6 ± 13.7) U/ml vs. (101.5 ± 14.0) U/ml and (89.1 ± 10.1) U/ml, P silicosis and evaluation of patient's condition.

    Our aim was to set up a system to help UK clinical research units to prevent healthy volunteers from participating in more than one non-therapeutic trial simultaneously, or from starting a second trial too soon after the first. TOPS (The Over-volunteering Prevention System) is internet-based, simple and quick to use, free to users and a charity run by a Board of Trustees. Users enter only two or three pieces of information: (1) 'National Insurance number' (NINO) of UK citizens, or 'passport number' and country of origin of non-UK citizens, as their identifier, (2) 'date of last dose' of trial medicine or (3) 'never dosed'. Subjects must consent, but TOPS collects only non-personal data, so it does not require Ethics Committee approval and is not covered by the Data Protection Act. A total of 55 research units (29 clinical research organisations, 5 pharmaceutical companies, 13 universities and 8 hospitals) throughout the UK have registered to use TOPS, and have entered 124,906 volunteers since we launched it. All commercial and many non-commercial units now use TOPS. In our unit, no subject has to the best of our knowledge participated in two trials simultaneously. TOPS has reduced to research units to comply with UK clinical trial regulations.

    Background. Metabolic and genetic factors induce plasminogen activator inhibitor type-1 (PAI-1) overexpression; higher PAI-1 levels decrease fibrinolysis and promote atherothrombosis. Aim. To assess PAI-1 antigen levels among subjects with type 2 diabetes mellitus (T2DM) plus Metabolic Syndrome (MetS) before clinical manifestations of atherothrombosis and the contribution of metabolic factors and 4G/5G polymorphism of PAI-1 gene on the variability of PAI-1. Methods. We conducted an observational, cross-sectional assay in a hospital in Mexico City from May 2010 to September 2011. MetS was defined by the International Diabetes Federation criteria. PAI-1 levels and 4G/5G polymorphism were determined by ELISA and PCR-RFLP analysis. Results. We enrolled 215 subjects with T2DM plus MetS and 307 controls. Subjects with T2DM plus MetS had higher PAI-1 levels than the reference group (58.4 ± 21 versus 49.9 ± 16 ng/mL, p = 0.026). A model with components of MetS explained only 12% of variability on PAI-1 levels (R(2) = 0.12; p = 0.001), with β = 0.18 (p = 0.03) for hypertension, β = -0.16 (p = 0.05) for NL HDL-c, and β = 0.15 (p = 0.05) for NL triglycerides. Conclusion. Subjects with T2DM plus MetS have elevated PAI-1 levels before clinical manifestations of atherothrombotic disease. Metabolic factors have a more important contribution than 4G/5G polymorphism on PAI-1 plasma variability.

    In pediatric dentistry, the experiences of dental students may help dental educators better prepare graduates to treat the children. Research suggests that student's perceptions should be considered in any discussion of their education, but there has been no systematic examination of India's undergraduate dental students learning experiences. This qualitative investigation aimed to gather and analyze information about experiences in pediatric dentistry from the students' viewpoint using critical incident technique (CIT). The sample group for this investigation came from all 240 3rd and 4th year dental students from all the four dental colleges in Indore. Using CIT, participants were asked to describe at least one positive and one negative experience in detail. They described 308 positive and 359 negative experiences related to the pediatric dentistry clinic. Analysis of the data resulted in the identification of four key factors related to their experiences: 1) The instructor; 2) the patient; 3) the learning process; and 4) the learning environment. The CIT is a useful data collection and analysis technique that provides rich, useful data and has many potential uses in dental education.

    Full Text Available Abstract Background A lot of studies have showed an excess maternal transmission of type 2 diabetes (T2D. The aim, therefore, of the present study was to estimate the prevalence of familial history of T2D in Greek patients, and to evaluate its potential effect on the patient's metabolic control and the presence of diabetic complications. Methods A total of 1,473 T2D patients were recruited. Those with diabetic mothers, diabetic fathers, diabetic relatives other than parents and no known diabetic relatives, were considered separately. Results The prevalence of diabetes in the mother, the father and relatives other than parents, was 27.7, 11.0 and 10.7%, respectively. Patients with paternal diabetes had a higher prevalence of hypertension (64.8 vs. 57.1%, P = 0.05 and lower LDL-cholesterol levels (115.12 ± 39.76 vs. 127.13 ± 46.53 mg/dl, P = 0.006 than patients with diabetes in the mother. Patients with familial diabetes were significantly younger (P 2, P = 0.08, higher prevalence of dyslipidemia (49.8 vs. 44.6%, P = 0.06 and retinopathy (17.9 vs. 14.5%, P = 0.08 compared with patients with no diabetic relatives. No difference in the degree of metabolic control and the prevalence of chronic complications were observed. Conclusion The present study showed an excess maternal transmission of T2D in a sample of Greek diabetic patients. However, no different influence was found between maternal and paternal diabetes on the clinical characteristics of diabetic patients except for LDL-cholesterol levels and presence of hypertension. The presence of a family history of diabetes resulted to an early onset of the disease to the offspring.

    The etiologic role of inflammatory pathways in the development of diabetic complications, especially cardiovascular events, has been established. The anti-inflammatory role of metformin and pioglitazone has been described; however, no study to date has compared the efficacy of these common oral agents in this regard. In this study, the authors aimed to compare the anti-inflammatory properties of pioglitazone and metformin, with respect to their effect on serum concentrations of highly sensitive C-reactive protein (hsCRP), osteoprotegerin (OPG), intercellular adhesion molecule-1 (ICAM-1) and adiponectin. In an open-label randomized clinical trial, 117 patients with newly diagnosed type 2 diabetes mellitus were visited; 84 fulfilled the inclusion criteria, and were randomly allocated to 2 arms receiving either 1,000 mg/d metformin or 30 mg/d pioglitazone, respectively. Biochemical assessments were made at baseline and the end of the 3 months trial. Significant reduction in FPG, insulin and HbA1c in women and men of both arms were observed. Log-hsCRP values significantly decreased in both arms. A decreasing, but non-significant trend in log-OPG levels was observed in women of the metformin arm (p=0.063). A greater reduction in log-ICAM levels was identifiable in men receiving pioglitazone compared to the other arm (p=0.008); in addition, the same trend was observed in log-OPG values (p=0.029). Nonetheless, reduction in log-ICAM and log-OPG levels was comparable between the 2 arms. A significant increase in adiponectin was observed in both men and women in the pioglitazone arm (pmetformin arm. Remarkably, patients receiving pioglitazone revealed more significant reduction in inflammatory markers. © Georg Thieme Verlag KG Stuttgart · New York.

    To assess the effects of two commonly used oral hypoglycemic medications metformin and pioglitazone on serum concentrations of omentin and leptin in patients with newly diagnosed type 2 diabetes. In a clinical trial setting (NCT01593371), patients were randomly allocated to either metformin 1000mg daily (n=41), or pioglitazone 30mg daily (n=50). Serum concentrations of omentin and leptin were measured at baseline and after 12weeks. Patients' weight, waist circumference, blood pressure, fasting plasma glucose, fasting insulin, HbA1c, highly sensitive C-reactive protein, and serum lipids were also measured at the two visits. Baseline concentrations of omentin and leptin were not different between the two arms of the trial. After three months, metformin decreased both omentin and leptin concentrations in women, and leptin concentrations only in men. On the other hand, pioglitazone reduced both adipokines only in women, but not men. Univariate and multivariate ANCOVA models revealed that both interventions are equally effective in reducing omentin concentration (p=0.497 for women and 0.344 for men in multivariate models controlling for the effects of confounding variables). Similarly, neither medication was more effective in reducing leptin concentrations after three months (p=0.822 for women and 0.441 for men in multivariate models). Metformin and pioglitazone at pharmacologic doses are equally effective in alteration of serum omentin and leptin concentrations in patients with diabetes, albeit sex differences in response to medications exist. Implication of these findings on long term management and complication prevention of diabetes needs to be elucidated. Copyright © 2013 Elsevier B.V. All rights reserved.

    Fetuin-A is a circulating glycoprotein capable of inhibiting insulin signaling both in vivo and in vitro and is positively associated with insulin resistance. Osteoprotegerin (OPG) acts as a regulatory molecule with increased levels in the early stages of diabetes and atherosclerosis, and is also associated with insulin resistance. We investigated the effects of pioglitazone and metformin as representative insulin-sensitizing therapies on fetuin-A and OPG levels. In a randomized clinical trial setting (NCT02027103), 88 patients with newly diagnosed type 2 diabetes were randomly assigned to pioglitazone (30 mg/day, n=46) or metformin (1000 mg/day, n=42) for 12 weeks. Various anthropometric and metabolic parameters, fetuin-A, OPG, highly sensitive C-reactive protein (hsCRP), and homeostasis model assessment of insulin resistance (HOMA-IR) were measured at baseline and after three months. The reduction in fasting plasma glucose and haemoglobin A1c levels was comparable in the two arms. Pioglitazone resulted in a significant reduction in both fetuin-A and OPG in men, but only fetuin-A in women. Metformin was only effective in lowering OPG levels in women. When compared, both medications were equally effective with regard to fetuin-A and OPG reduction in women (p=0.413 and 0.359, respectively). In men, pioglitazone more effectively decreased fetuin-A levels in both uni- (p=0.011) and multivariate models (p=0.015) and OPG levels in only uni- (p=0.023) but not the multivariate model (p=0.547). Metformin and pioglitazone differentially affect fetuin-A and osteoprotegrin levels in diabetic women and men. The level of change may not necessarily be associated with the amelioration of insulin resistance. Copyright © 2014 Diabetes India. Published by Elsevier Ltd. All rights reserved.

    Technical innovation of autoimmune blistering dermatoses (ABDs) diagnosis aimed at multiplex approach. Two multiparametric ELISA tests are commercially available for ABDs serology. The aim was to compare diagnostic accuracy of multiparametric and monospecific ELISAs and to examine the diagnostic value/agreement of multivariant ELISA in compliance with traditional diagnostic setup for ABDs. In total, 128 sera from suspected ABDs patients were studied (27 sera in order to compare ELISAs). Multivariant ELISA (detection of IgG against desmoglein 1 and 3 - DSG1/3; BP180, BP230, envoplakin, type VII collagen), monovariant ELISA, and statistical analysis were performed. With the use of sera from patients with suspected ABDs, the multiparametric ELISA yield an agreement of 84% with traditional stepwise diagnostics. Multivariant ELISA with BP180 and BP230 showed 87.5% and 80% sensitivity, 87.5% and 91% specificity, 87.5% reliability as well as 87.5% and 80% positive predictive value, 87.5% and 91% negative predictive value, respectively, in relation to monospecific ELISA. Multivariant ELISA with DSG1 and DSG3 showed 50% and 80% sensitivity, 100% and 80% specificity, 85% and 80% reliability as well as 100% and 57% positive predictive value, 82% and 92% negative predictive value, respectively, in relation to monospecific ELISA. A better rate of agreement was observed among ELISA systems with BP180 and BP230, than with ELISA systems with DSG1 and DSG3. Multivariant ELISA test combined with clinical examinations and DIF is recommended as a minimal approach to diagnosing ABDs in ethnic Slavs. © 2017 Wiley Periodicals, Inc.

    We present the protocol for a multifactorial intervention study designed to test whether individualised treatment, based on pathophysiological phenotyping and individualised treatment goals, improves type 2 diabetes (T2D) outcomes. We will conduct a prospective controlled multicentre open-label intervention study, drawing on the longitudinal cohort of the Danish Centre for Strategic Research in Type 2 Diabetes (DD2). New clinically diagnosed patients with T2D in the intervention group will be assigned to receive individualised treatment by their general practitioner. Intervention patients will be compared with a matched control cohort of DD2 patients receiving routine clinical care. Among intervention patients, we will first do pathophysiological phenotyping to classify patients into WHO-defined T2D or other specific types of diabetes (monogenic diabetes, secondary diabetes etc). Patients with WHO-defined T2D will then be further subcharacterised by their beta-cell function (BCF) and insulin sensitivity (IS), using the revised homeostatic assessment model, as having either insulinopaenic T2D (high IS and low BCF), classical T2D (low IS and low BCF) or hyperinsulinaemic T2D (low IS and high BCF). For each subtype, a specific treatment algorithm will target the primary pathophysiological defect. Similarly, antihypertensive treatment will be targeted at the specific underlying pathophysiology, characterised by impedance cardiography (relative importance of vascular resistance, intravascular volume and cardiac inotropy). All treatment goals will be based on individual patient assessment of expected positive versus adverse effects. Web-based and face-to-face individualised lifestyle intervention will also be implemented to empower patients to make a sustainable improvement in daily physical activity and to change to a low-carbohydrate diet. The study will use well-known pharmacological agents according to their labels; patient safety is therefore considered high. Study

    Full Text Available To predict drug-induced serious adverse events (SAE in clinical trials, a model using a panel of cells derived from human induced pluripotent stem cells (hiPSCs of individuals with different susceptibilities could facilitate major advancements in translational research in terms of safety and pharmaco-economics. However, it is unclear whether hiPSC-derived cells can recapitulate interindividual differences in drug-induced SAE susceptibility in populations not having genetic disorders such as healthy subjects. Here, we evaluated individual differences in SAE susceptibility based on an in vitro model using hiPSC-derived cardiomyocytes (hiPSC-CMs as a pilot study. hiPSCs were generated from blood samples of ten healthy volunteers with different susceptibilities to moxifloxacin (Mox-induced QT prolongation. Different Mox-induced field potential duration (FPD prolongation values were observed in the hiPSC-CMs from each individual. Interestingly, the QT interval was significantly positively correlated with FPD at clinically relevant concentrations (r > 0.66 in multiple analyses including concentration-QT analysis. Genomic analysis showed no interindividual significant differences in known target-binding sites for Mox and other drugs such as the hERG channel subunit, and baseline QT ranges were normal. The results suggest that hiPSC-CMs from healthy subjects recapitulate susceptibility to Mox-induced QT prolongation and provide proof of concept for in vitro preclinical trials.

    Lack of African American participation in cancer clinical trials has been identified as a critical problem. Historical interactions related to race, identity, and power may contribute to continued inequity in healthcare and research participation. The aim of this study was to explore the perceptions of African Americans regarding cancer and research and how these perceptions shape their beliefs about participating as cancer research subjects. Three African American focus groups were conducted including people who had never participated in cancer research, those who had, and those who were asked but refused (n = 16). Discussion focused on their perceptions of cancer research and actual or potential participation as research subjects. Data were coded using both structured and inductive coding methods. Fear and fatalism emerged in relation to research, race, power, and identity and were related to larger historical and social issues rather than only individual thoughts or feelings. Participants described fears of the unknown, death, mistrust, conspiracy, and discrimination together with positive/negative tensions between self, family, and community responsibilities. Complex identities linked perceptions of cancer and cancer research with broader historical and cultural issues. Fear, fatalism, and current and historical relationships influence how people perceive themselves as research subjects and may influence their decisions to participate in cancer research. Acknowledging how complex factors including race and racism contribute to health disparities may give nurses and other healthcare providers a better appreciation of how historical, social, and cultural dynamics at individual, community, and organizational levels influence access to and participation in cancer research.

Twenty-seven subjects with elevated UAE were compared with 46 matched...... controls with normoalbuminuria. Plasma concentration of ET-1 was measured using an ELISA method and plasma concentration of nitrate/nitrite using a photometric method. Twenty-four-hour blood pressure was measured using a portable recorder (TM-2421). No significant differences in the concentrations...... of nitrate/nitrite and ET-1 were found between the groups, e.g. 21 (10-105) vs. 18 (11 -152) (p=0.33) and 0.98 (0.58 1.95) vs. 1.10 (0.54 -1.50) (p = 0.27), respectively.

    Research on the environmental risk factors for schizophrenia has focused on either psychosocial stress or drug exposure, with limited investigation of their interaction. A heightened dopaminergic stress response in patients with schizophrenia and individuals at clinical high risk (CHR) supports the dopaminergic sensitization hypothesis. Cannabis is believed to contribute to the development of schizophrenia, possibly through a cross-sensitization with stress. Twelve CHR and 12 cannabis-using CHR (CHR-CU, 11 dependent) subjects underwent [11C]-(+)-PHNO positron emission tomography scans, while performing a Sensorimotor Control Task (SMCT) and a stress condition (Montreal Imaging Stress task). The simplified reference tissue model was used to obtain binding potential relative to non-displaceable binding (BPND) in the whole striatum, its functional subdivisions (limbic striatum (LST), associative striatum (AST), and sensorimotor striatum (SMST)), globus pallidus (GP), and substantia nigra (SN). Changes in BPND, reflecting alterations in synaptic dopamine (DA) levels, were tested with analysis of variance. SMCT BPND was not significantly different between groups in any brain region (p>0.21). Although stress elicited a significant reduction in BPND in the CHR group, CHR-CU group exhibited an increase in BPND. Stress-induced changes in regional BPND between CHR-CU and CHR were significantly different in AST (p<0.001), LST (p=0.007), SMST (p=0.002), SN (p=0.021), and whole striatum (p=0.001), with trend level in the GP (p=0.099). All subjects experienced an increase in positive (attenuated) psychotic symptoms (p=0.001) following the stress task. Our results suggest altered DA stress reactivity in CHR subjects who concurrently use cannabis, as compared with CHR subjects. Our finding does not support the cross-sensitization hypothesis, which posits greater dopaminergic reactivity to stress in CHR cannabis users, but adds to the growing body of literature showing reduced DA

    Full Text Available CONTEXT: Researchers and investigators have argued that getting fully informed written consent may not be possible in the developing countries where illiteracy is widespread. AIMS: To determine the percentage of patients who agree to participate in a trial after receiving either complete or partial information regarding a trial and to find out whether there were gender or educational status-related differences. To assess reasons for consenting or refusing and their depth of understanding of informed consent. SETTINGS AND DESIGN: A simulated clinical trial in two tertiary health care facilities on in-patients. METHODS AND MATERIAL: An informed consent form for a mock clinical trial of a drug was prepared. The detailed / partial procedure was explained to a purposive sample of selected in-patients and their consent was asked for. Patients were asked to free list the reasons for giving or withholding consent. Their depth of understanding was assessed using a questionnaire. Chi-square test was used for statistical analyses. RESULTS: The percentages of those consenting after full disclosure 29/102 (30% and after partial disclosure 15/50 (30% were the same. There was a significant (p=0.043 gender difference with a lesser percentage of females (30% consenting to participation in a trial. Educational status did not alter this percentage. Most patients withheld consent because they did not want to give blood or take a new drug. Understanding of informed consent was poor in those who consented. CONCLUSIONS: The fact that only one-third of subjects are likely to give consent to participate in a trial needs to be considered while planning clinical trials with a large sample size. Gender but not educational status influences the number of subjects consenting for a study. Poor understanding of the elements of informed consent in patients necessitates evolving better methods of implementing consent procedures in India.

    Previous research has linked cognitive insight (a measure of self-reflectiveness and self-certainty) in psychosis with neurocognitive and neuroanatomical disturbances in the fronto-hippocampal neural network. The authors' goal was to use functional magnetic resonance imaging (fMRI) to investigate the neural correlates of cognitive insight during an external source memory paradigm in non-clinical subjects. At encoding, 24 non-clinical subjects travelled through a virtual city where they came across 20 separate people, each paired with a unique object in a distinct location. fMRI data were then acquired while participants viewed images of the city, and completed source recognition memory judgments of where and with whom objects were seen, which is known to involve prefrontal cortex. Cognitive insight was assessed with the Beck Cognitive Insight Scale. External source memory was associated with neural activity in a widespread network consisting of frontal cortex, including ventrolateral prefrontal cortex (VLPFC), temporal and occipital cortices. Activation in VLPFC correlated with higher self-reflectiveness and activation in midbrain correlated with lower self-certainty during source memory attributions. Neither self-reflectiveness nor self-certainty significantly correlated with source memory accuracy. By means of virtual reality and in the context of an external source memory paradigm, the study identified a preliminary functional neural basis for cognitive insight in the VLPFC in healthy people that accords with our fronto-hippocampal theoretical model as well as recent neuroimaging data in people with psychosis. The results may facilitate the understanding of the role of neural mechanisms in psychotic disorders associated with cognitive insight distortions. © 2014 The Authors.

    To systematically review the qualitative evidence on factors that affect the experience of patients attending nurse-led clinics and compare with key elements of person-centred care. As the number of nurse-led clinics increases in response to health system needs, evaluation has focused on clinical outcomes and cost. Patient experiences are less researched and yet, they are an important influence on clinical outcomes and an indicator of person-centred care. A detailed review of existing research in this area is needed. A systematic review of primary, qualitative literature was conducted using the Joanna Briggs Institute methodology of meta-aggregation. Published research from 1990-2012 was located using CINAHL, PubMed, Medline and PsycINFO. Reference lists were searched and analysed. Two reviewers assessed the papers for methodological quality using instruments from the Joanna Briggs Institute to critically appraise, extract data and meta-aggregate findings. Eleven studies met all inclusion criteria. Three meta-synthesis statements were derived from 46 findings aggregated to nine categories. The key themes relating to establishment of a therapeutic relationship, effective communication, and clinical skills and collaboration mapped closely to the person-centred care framework. Concepts central to person-centred care proved to be factors impacting patients' subjective experience. Further research is warranted to meet the challenge to transform the key concepts of the person-centred care model into everyday nursing practice. Knowledge of patients' feelings and the importance of person-centred, individualised care may contribute to development of future training and re-training programs in basic nursing skills. This is significant in that it contributes to future positive patient experience. © 2014 John Wiley & Sons Ltd.

    An increasing number of clinical trials are conducted in primary care settings. Making better use of existing data in the electronic health records to identify eligible subjects can improve efficiency of such studies. Our study aims to quantify the proportion of eligibility criteria that can be addressed with data in electronic health records and to compare the content of eligibility criteria in primary care with previous work. Eligibility criteria were extracted from primary care studies downloaded from the UK Clinical Research Network Study Portfolio. Criteria were broken into elemental statements. Two expert independent raters classified each statement based on whether or not structured data items in the electronic health record can be used to determine if the statement was true for a specific patient. Disagreements in classification were discussed until 100 % agreement was reached. Statements were also classified based on content and the percentages of each category were compared to two similar studies reported in the literature. Eligibility criteria were retrieved from 228 studies and decomposed into 2619 criteria elemental statements. 74 % of the criteria elemental statements were considered likely associated with structured data in an electronic health record. 79 % of the studies had at least 60 % of their criteria statements addressable with structured data likely to be present in an electronic health record. Based on clinical content, most frequent categories were: "disease, symptom, and sign", "therapy or surgery", and "medication" (36 %, 13 %, and 10 % of total criteria statements respectively). We also identified new criteria categories related to provider and caregiver attributes (2.6 % and 1 % of total criteria statements respectively). Electronic health records readily contain much of the data needed to assess patients' eligibility for clinical trials enrollment. Eligibility criteria content categories identified by our study can be

    Imepitoin is a novel antiepileptic drug for the treatment of canine idiopathic epilepsy. The present study was conducted to demonstrate superior antiepileptic activity of a high dose of 30 mg/kg BID over a low dose of 1 mg/kg BID of imepitoin during 12 weeks of treatment under double blind conditions in a field population of dogs with previously untreated epilepsy. In a consecutive 12 weeks open label follow up (phase 2), all animals received 30 mg/kg BID, to evaluate the persistence of the antiepileptic activity, and to evaluate the effect of a dose step up to 30 mg/kg in the former low-dose animals. A treatment with 30 mg/kg BID resulted in a significantly greater reduction in monthly seizure frequency relative to baseline data as compared to the 1 mg/kg dose. Both generalized and partial seizures but not cluster seizures were significantly less frequent in the high dose group. The antiepileptic activity was maintained during study phase 2 in the high dose group. An increase to 30 mg/kg BID in the low- dose animals resulted in a significant reduction in generalized and partial seizures, but not cluster seizures. At the end of study phase 2, 32.1 and 46.8 % of dogs of the former high and former low-dose groups respectively, remained free of generalized tonic-clonic seizures. Imepitoin was well tolerated. The frequency of dogs with any adverse drug reactions was higher in the 30 mg/kg BID dose (59 % vs. 41 %, p = 0.041), and the main target organ was the central nervous system (CNS). The occurrence of CNS related adverse reactions was transient and findings were mostly restricted to the first weeks of treatment. No hepatic enzyme increase and no other organ toxicity were observed. The administration of imepitoin twice daily at a dose of 30 mg/kg results in significant and persistent antiepileptic effects in patients with newly diagnosed epilepsy and generalized tonic-clonic seizures, as observed over a study period of up to 6 months. Imepitoin was well tolerated

    Lipoatrophy is a condition that affects certain individuals, most commonly those who are infected with the human immunodeficiency virus.(1-3) Injectable fillers are used for the treatment of these dermal contour deformities to smooth dermal depressions formed by the loss of volume. These dermal fillers (also known as soft tissue augmentation devices) can correct contour deformities caused by lipoatrophy in patients who are human immunodeficiency virus positive or negative. The product used in this study is a patented, second-generation, injectable, dermal collagen stimulator that combines glycolic acid and polylactic acid. The glycolic acid used is not a polymer, but rather an acid derived from sugar cane. Its chemical structure corresponds to that of an alpha-hydroxy acid. Glycolic acid is a well-characterized agent that is present in a number of cosmetic products. Polylactic acid is a synthetic, biocompatible, biodegradable, inert, synthetic polymer from the poly a-hydroxy-acid family that is believed to stimulate fibroblasts to produce more collagen, thus increasing facial volume. Together, polylactic acid and glycolic acid act in concert to 1) stimulate collagen production and 2) hydrate the outer layers of the skin. A multicenter, clinical investigation authorized by the Mexican Secretariat of Health was conducted between September 20, 2002, and September 19, 2004. This clinical study was conducted in male patients between 32 and 60 years of age with lipoatrophy as a result of highly active antiretroviral therapy for human immunodeficiency virus infection. The study objective was to measure the improvement of contour deformities after the injection of a dermal collagen stimulator containing glycolic acid and polylactic acid. In addition to safety, this dermal filler was assessed when used to correct volume deformities caused by lipoatrophy in subjects who are human immunodeficiency virus positive. Thirty male subjects participated and were treated as follows

    Percent subjects with no heavy drinking days (PSNHDDs), an efficacy end point recommended by the Food and Drug Administration, considers abstinent individuals or those engaging in low-risk drinking behavior as successful responders to treatment. As PSNHDD has been used infrequently in previous alcohol clinical trials, we evaluated the utility and validity of the PSNHDD outcome measure in 2 large alcohol clinical trials. Data sets from 2 alcohol trials, COMBINE and a multisite topiramate trial, were used to analyze PSNHDDs and other traditional end points for the topiramate, naltrexone, acamprosate, and placebo groups. Effect sizes of PSNHDDs were determined for each month of active treatment and by varying grace periods-early periods in the trial where outcome is not considered in the analysis-and were compared with that of other traditional outcome measures. Long-term outcomes were compared for groups that had no heavy drinking days versus those that had heavy drinking days during active treatment. PSNHDD effect sizes were significant for both topiramate (0.34 and 0.25 at months 2 and 3, respectively) and naltrexone (0.24 and 0.26 at months 3 and 4, respectively). Given a 2-month grace period for naltrexone, the effect size of PSNHDDs was comparable to the effect sizes using traditional outcome measures. With a 1-month grace period for topiramate, it was greater than the majority of traditional outcome measures. Little is gained by allowing up to 1, 2, or 3 heavy drinking days as an end point. Subjects with no HDDs during treatment fared better than those with some HDDs on drinking outcomes and alcohol-related consequences during a 1-year follow-up. PSNHDD appears to be a clinically informative end point measure, especially when used with a grace period, and is as sensitive as most traditional outcome measures in detecting differences between the medication and placebo groups. Nonetheless, these findings should be replicated in other clinical data sets

    Men who have sex with men (MSM) have an increased incidence of pathogens transmitted by the oro-fecal route. Hepatitis E virus (HEV) is an emerging cause of acute hepatitis and fecal shedding is observed during primary infection. We investigated whether MSM are at increased risk of HEV infection. Subjects who attended a sexually transmitted infection clinic in Brussels and had an HIV test performed between 1 June 2014 and 15 January 2016 were identified. A total of 576 samples were retrospectively screened for both total HEV IgG and HEV RNA. Samples positive for IgG were tested for IgM. MSM proportion was 31·1% (179/576). Overall HEV IgG prevalence was 9·03% (52/576) and was identical in MSM and heterosexual subjects. Among the IgG positive samples, 2/52 (3·84%) samples (both women) were positive for anti-HEV IgM. No sample was positive for HEV RNA. Age over 35 was the only risk factor significantly associated with HEV seropositivity (OR 2·07; 95% CI 1·16-3·67). In conclusion, MSM were not found to have an increased prevalence of HEV as previously reported in other European countries suggesting distinct dynamics of HEV infection in this group across Europe and increased age was associated with a higher risk of seropositivity.

    Full Text Available Hemoglobinopathies are among the most common autosomal-recessive disorders worldwide. A comprehensive next-generation sequencing (NGS test would greatly facilitate screening and diagnosis of these disorders. An NGS panel targeting the coding regions of hemoglobin genes and four modifier genes was designed. We validated the assay by using 2522 subjects affected with hemoglobinopathies and applied it to carrier testing in a cohort of 10,111 couples who were also screened through traditional methods. In the clinical genotyping analysis of 1182 β-thalassemia subjects, we identified a group of additional variants that can be used for accurate diagnosis. In the molecular screening analysis of the 10,111 couples, we detected 4180 individuals in total who carried 4840 mutant alleles, and identified 186 couples at risk of having affected offspring. 12.1% of the pathogenic or likely pathogenic variants identified by our NGS assay, which were undetectable by traditional methods. Compared with the traditional methods, our assay identified an additional at-risk 35 couples. We describe a comprehensive NGS-based test that offers advantages over the traditional screening/molecular testing methods. To our knowledge, this is among the first large-scale population study to systematically evaluate the application of an NGS technique in carrier screening and molecular diagnosis of hemoglobinopathies.

    Hyperhidrosis is a common medical condition which can have a significant impact on quality of life. Umeclidinium (UMEC) is a long-acting muscarinic antagonist (LAMA) developed as a dermal formulation. This 2-week, double-blind, randomized, vehicle-controlled study evaluated systemic exposure, safety and tolerability of topically administered UMEC in subjects with primary axillary hyperhidrosis. Clinical effect was a secondary objective, measured by gravimetry and the hyperhidrosis disease severity scale (HDSS). Vehicle was included to evaluate safety. Twenty-three subjects were randomized to either 1.85% UMEC (N = 18) or vehicle (N = 5) once daily. Measurable plasma concentrations were observed in 78% of subjects after the treatment. Nine subjects (50%) on UMEC and two subjects (40%) on vehicle reported AEs, most commonly application site reactions. At Day 15, seven subjects (41%) in UMEC and two subjects (40%) in vehicle had at least a 50% reduction in sweat production. Eight subjects (47%) in UMEC and one subject (20%) in vehicle had at least a two-point reduction in HDSS. No comparisons of treatment arms were planned prospectively. The measurable exposure, acceptable safety and preliminary clinical activity observed in this proof-of-concept study suggest the potential clinical utility of topical UMEC in subjects with axillary hyperhidrosis. © 2017 European Academy of Dermatology and Venereology.

  4. Diagnosing Musculoskeletal Tumours

    2001-01-01

    Full Text Available In 1993 we became aware of a worrying increase in apparent errors in the histopathological diagnosis of musculoskeletal tumours in our Unit. As a result all cases seen over the past 8 years were reviewed by an independent panel. Of the 1996 cases reviewed there was an error in 87. In 54 cases (2.7% this had led to some significant change in the active management of the patient. The main areas where errors arose were in those very cases where clinical and radiological features were not helpful in confirming or refuting the diagnosis. The incidence of errors rose with the passage of time, possibly related to a deterioration in the pathologist’s health. The error rate in diagnosing bone tumours in previously published series ranges from 9 to 40%. To ensure as accurate a rate of diagnosis as possible multidisciplinary working and regular audit are essential.

    Full Text Available Introducción: El proceso de medicalización de la sociedad ha generado una dependencia de la biomedicina para entender, gestionar y legitimar la enfermedad. Como consecuencia surge una nueva forma de considerar los procesos corporales que transforma las identidades y subjetividades de los individuos y los grupos sociales. La enfermedad se concibe y se experimenta en el cuerpo en forma de signos y síntomas. Esta representación de la enfermedad compartida por expertos y enfermos durante el encuentro clínico se convierte en el lenguaje propio de la interacción. Esto ocurre incluso en casos, como el de la fibromialgia, en los que el diagnóstico se produce en ausencia de alteraciones ‘objetivas’ del cuerpo. Metodología: Observación participante, sobre la elaboración y comunicación del diagnóstico de fibromialgia en una consulta de reumatología. Resultados: Se analizan las representaciones sobre el cuerpo y la enfermedad que manejan tanto médicos como enfermos, y la utilización de los síntomas corporales como estrategia de legitimación e interacción durante el encuentro clínico. Conclusión: En la fibromialgia, a pesar de la ausencia de alteraciones biológicas ‘objetivas’, la relación sanitario-paciente se ve mediada por el cuerpo. Este es el lugar en el que se producen las intervenciones terapéuticas y el vehículo de la comunicación entre ambos.Introduction: The process of medicalization of the society has generated a dependence of the biomedicine to understand, to negotiate and to legitimate the illness.

    Full Text Available OBJECTIVE: To describe the quantitative treatment outcomes of patients undergoing acoustic coordinated reset (CR neuromodulation at a single independent audiology practice over a 22 – 26 week period as part of an open label, non-randomized, non-controlled observational study.Methods: Sixty six patients with subjective tonal tinnitus were treated with acoustic CR Neuromodulation with a retrospective review of patient records being performed in order to identify changes of visual analogue scale (VAS, n=66 and in the score of the Tinnitus Handicap Questionnaire (THQ, n =51. Patients had their tinnitus severity recorded prior to the initiation of therapy using the Tinnitus Handicap Inventory (THI in order to categorize patients into slight up to catastrophic impact categories. THQ and VAS for tinnitus loudness / annoyance were obtained at the patient’s initial visit, at 10-14 weeks and 22-26 weeks. RESULTS: VAS scores were significantly improved, demonstrating a 25.8% mean reduction in tinnitus loudness and a 32% mean reduction in tinnitus annoyance with a clinically significant reduction in percept loudness and annoyance being recorded in 59.1% and 72.7% of the patient group. THQ scores were significantly improved by 19.4% after 22-26 weeks of therapy compared to baseline. CONCLUSION: Acoustic CR neuromodulation therapy appears to be a practical and promising treatment for subjective tonal tinnitus. However, due to the lack of a control group it is difficult to reach an absolute conclusion regarding to what extent the observed effects are related directly to the acoustic CR neuromodulation therapy. Also as the observed patient group was made up of paying clients it is unknown as to whether this could have caused any additional placebo like effects to influence the final results.

    In the period of 3 years, 9 tumours of chemodectoma were supravitally diagnosed and histopathologically verified in dogs. In this period 15 351 dogs were admitted to the Clinic of Dogs and Cats and 2 145 dogs were examined in the cardiological outpatient clinic for dogs. This tumour is located in a typical place--at the base of the heart. Most frequently the tumour manifested in older boxers. Only in one case such a tumour was diagnosed in another breed of dogs. The tumours ranged in size between 3 and 16 cm in diameter. The principal sign accompanying tumours of cardiac base involved dyspnoea but in 3 cases the tumours yielded no clinical signs. All the diagnoses were additionally verified using immunohistochemical examination. We used antibodies to chromogranin A (clone DAK-A3 1:100), synaptophysin (clone SY38 1:20) and neuron-specific enolase (clone BBS/NC/VI-H14 1:150). An immunohistochemical examination is vital for the diagnosis since it allows to differentiate histologically distinct types of neoplasia which may locate in the same site and may manifest a similar histological pattern.

    A real-time PCR assay was developed to identify varicella-zoster virus (VZV) and herpes simplex virus (HSV) DNA in clinical specimens from subjects with suspected herpes zoster (HZ; shingles). Three sets of primers and probes were used in separate PCR reactions to detect and discriminate among wild-type VZV (VZV-WT), Oka vaccine strain VZV (VZV-Oka), and HSV DNA, and the reaction for each virus DNA was multiplexed with primers and probe specific for the human β-globin gene to assess specimen adequacy. Discrimination of all VZV-WT strains, including Japanese isolates and the Oka parent strain, from VZV-Oka was based upon a single nucleotide polymorphism at position 106262 in ORF 62, resulting in preferential amplification by the homologous primer pair. The assay was highly sensitive and specific for the target virus DNA, and no cross-reactions were detected with any other infectious agent. With the PCR assay as the gold standard, the sensitivity of virus culture was 53% for VZV and 77% for HSV. There was 92% agreement between the clinical diagnosis of HZ by the Clinical Evaluation Committee and the PCR assay results. PMID:19475609

    Subjective cognitive impairment (SCI) is a trigger for seeking health care in a possible preclinical phase of Alzheimer's disease (AD), although the characteristics of SCI need clarification. We investigated the prevalence of psychosocial stress, depressive symptoms and CSF AD biomarkers in SCI and MCI (mild cognitive impairment). Memory clinic patients (SCI: n = 90; age: 59.8 ± 7.6 years; MCI: n = 160; age: 63.7 ± 7.0 years) included in the Gothenburg MCI study were examined at baseline. Variables were analyzed using logistic regression with SCI as dependent variable. Stress was more prevalent in SCI (51.1%) than MCI (23.1%); p patients had more previous depressive symptoms (p = 0.006), but showed no difference compared to MCI patients considering current depressive symptoms. A positive CSF AD profile was present in 14.4% of SCI patients and 35.0% of MCI patients (p = 0.001). Stress (p = 0.002), previous stress/depressive symptoms (p = 0.006) and a negative CSF AD profile (p = 0.036) predicted allocation to the SCI group. Psychosocial stress is more prevalent in SCI than previously acknowledged. The high prevalence and long-term occurrence of stress/depressive symptoms in SCI in combination with a low prevalence of altered CSF AD biomarkers strengthens the notion that AD is not the most likely etiology of SCI. © 2016 S.

    Older adults frequently report problems of transportation. Little is known about the correlates of transportation deficiency in Latin America. Therefore, the aim of the present study was to determine the correlates of subjective transportation deficiency (STD) among community-dwelling older adults attending a tertiary care hospital in Mexico City. Cross-sectional study of 228 participants aged ≥70 years being followed in any of the outpatient clinics of a tertiary care hospital in Mexico City. Data were obtained through a structured questionnaire. Univariate and multivariate logistic regression analyses were carried out in order to identify the correlates of STD. The mean age of the participants was 79.8 years (SD 6.4) and 67.1% were women. STD was present in 46% of participants. The multivariate logistic regression model showed that female sex, illiteracy, mobility disability and the use of an assistive walking device had an independent and statistically significant association with STD. Female sex, illiteracy, mobility disability and the use of an assistive walking device were independent correlates of STD in the present study. Identifying the frequency and correlates of transportation deficiency in vulnerable populations will allow for the identification and implementation of useful public policies, as well as for the optimization of prevention and treatment strategies in an attempt to preserve mobility and autonomy, especially in low- and middle-income countries where previous work on transportation deficiency is lacking.

    Subjective quality of life (SQoL) has been increasingly studied in first-episode psychosis (FEP). Prior research primarily examined the impact of psychiatric symptoms on SQoL. Relationship between treatment-related factors and SQoL is under-studied. In this study, 159 Chinese patients who had completed 2-year treatment from early intervention service in Hong Kong were recruited. Assessments on premorbid adjustment, clinical profiles including social anxiety measure, functioning, antipsychotic-induced extrapyramidal side-effects and attitude toward medication treatment were conducted. SQoL was evaluated by Chinese version SF36 which generated mental and physical component summary (MCS and PCS) scores for analysis. Our results showed that more severe positive symptoms, higher level of depression, greater social anxiety, more negative attitude toward antipsychotic medications and greater degree of akathisia independently predicted lower MCS score. Higher social anxiety level and poorer functioning predicted lower PCS score. Our results indicate that affective and positive symptoms, functioning, and treatment-related variables are critical determinants of SQoL in FEP patients. These identified factors thus represent potentially malleable therapeutic targets for early detection and prompt intervention to promote enhancement of SQoL in the early stage of illness.

    The half-time clearance of an inhaled aerosol of /sup 99m/-technetium-labelled diethylene triamine pentacetate from lung to blood (T1/2LB) was measured using a gamma camera in 20 non-smoking subjects (mean age 54, range 40-69 years) with previous occupational asbestos exposure, but no clinical or radiological evidence of asbestosis, and 20 non-smoking normal subjects (mean age 54, range 40-62). Mean T1/2LB was 44.7 minutes (range 12-102) in exposed subjects, significantly less than 57.2 minutes (range 30.5-109) in normal subjects (P less than 0.05). There was no correlation between age and T1/2LB in either group. In exposed subjects T1/2LB showed a weak rank correlation with the membrane component of DLco (Dm) (r = 0.40, P less than 0.05) but no significant correlation with FVC, TLC, DLco, Kco, resting Pao2 or change in Pao2 on exercise. In six exposed subjects T1/2LB was shorter than in any of the normal subjects. These six did not differ from the other 14 exposed subjects in any physiological variables. T1/2LB is abnormal in some asbestos-exposed subjects without clinical, radiological or physiological evidence of asbestosis. Follow-up will show whether it is an early indicator of development of interstitial lung disease.

    The HIV infection is a problem of public health in Côte d'Ivoire. Voluntary screening is encouraged for the premature management of HIV infected patients before the stage of serious opportunist affections. Antiretroviral therapy became free. The purpose of this study was to describe the characteristics of HIV infected subject infected in hospitalization of pneumology. Our retrospective and analytic study concerned the activity period from January 2001 to December 2012 of pneumology department of Cocody university hospital. On 1141 recorded files, the prevalence of HIV infection was 48.20%. The multi-varied analysis showed the following results. Male patients were less HIV infected (OR=0.490 [0.363-0.661]) as the old patients of more than 64 years (OR=0.150 [0.080-0.280]). In case of HIV infection, infectious pathology, severe anemia and renal insufficiency were dominating respectively with OR=1.763 (1.212-2.564), OR=3.167 (2.125-4.720) and OR=2.054 (1.335-3.161). A stronger mortality was associated with HIV infection (OR=1.920 [1.312-2.809]). HIV infection always remains frequented in pneumology hospitalization in Abidjan with late discovery, source of complications and abnormally high death rate. Copyright © 2015 Elsevier Masson SAS.

    Full Text Available Diabetic ketoacidosis (DKA is one of the most serious acute complications of type 1 diabetes (T1D and the leading cause of morbidity and mortality in children with T1D. This study was aimed at assessing the prevalence and associated factors of DKA in children with newly diagnosed T1D in Addis Ababa.A hospital based cross-sectional study was conducted in selected hospitals in Addis Ababa. Children below the age of 12 years with DKA who were admitted to the pediatric ward in the selected hospitals between January 2009 and December 2014 and the residence of Addis Ababa were included. DKA was defined as children below the age of 12 years who have blood glucose level ≥250mg/dl, ketonuria, and ketonemia and diagnosed being T1D patient for the first time. Descriptive statistics was performed using frequency distribution, mean, median, tables, and graphs. Logistic regression analysis was used to identify independent factors associated with the prevalence of DKA in children with newly diagnosed T1D.Of 395 DKA patients who were hospitalized during the five-year period, 142(35.8% presented with DKA at first diagnosis of diabetes. On the other hand 253 (64.2% children with DKA had longstanding T1D. Independent factors associated with DKA include: Age category 2-4.49years, 7-9.49 years and ≥9.5years (Adjusted odd ratio (AOR = 3.14[1.21,8.06], 3.44(1.39,8.49 and 4.02(1.68,9.60, respectively; parents' knowledge on the sign and sy
