  2. Patient Safety, Present and Future

    Health care tends to oversimplify patient safety concepts. We tend to think about patient safety as a linear dimension that is only associated with the progressive reduction in the number of errors and accidents, with the simple notion that fewer are always better. We consider figures in isolation from the underlying context and prerequisites that drive safety models and the reality of the clinical fields. There is no one ultimate reference model of safety, but many models that can be adapted to fit the various clinical fields requirements and constraints. It is therefore not necessarily a bad result to observe a lower safety figure in a medical domain compared to the figures obtained in nonmedical ultra-safe models. The poor figures may represent the best local safety optimization while coping with the special health care requirements such as a high frequency of unplanned and nonstandard challenges. The paper distinguishes three classes of safety models that fit different field demands: the resilient and adaptive model, the high reliability (HRO) model, and the ultra-safe model. The lecture benchmarks the traits of each model while highlighting the specific dimensions for optimization. The conclusion is that firstly, that since the task requirements dictate the relevance and choice of the model and not the other way around, it is counterproductive to impose a model that is inadequate for the task requirements. Either you move the requirements and change the model, or you keep the constraints, and try to locally optimize the model to the clinical and organizational needs. (author)

    In the last decade, there was been increasing interest in finding imaging techniques able to provide a functional vascular imaging of the thoracic aorta. The purpose of this paper is to present an imaging method combining magnetic resonance imaging (MRI) and computational fluid dynamics (CFD) to obtain a patient-specific haemodynamic analysis of patients treated by thoracic endovascular aortic repair (TEVAR). MRI was used to obtain boundary conditions. MR angiography (MRA) was followed by cardiac-gated cine sequences which covered the whole thoracic aorta. Phase contrast imaging provided the inlet and outlet profiles. A CFD mesh generator was used to model the arterial morphology, and wall movements were imposed according to the cine imaging. CFD runs were processed using the finite volume (FV) method assuming blood as a homogeneous Newtonian fluid. Twenty patients (14 men; mean age 62.2 years) with different aortic lesions were evaluated. Four-dimensional mapping of velocity and wall shear stress were obtained, depicting different patterns of flow (laminar, turbulent, stenosis-like) and local alterations of parietal stress in-stent and along the native aorta. A computational method using a combined approach with MRI appears feasible and seems promising to provide detailed functional analysis of thoracic aorta after stent-graft implantation. • Functional vascular imaging of the thoracic aorta offers new diagnostic opportunities • CFD can model vascular haemodynamics for clinical aortic problems • Combining CFD with MRI offers patient specific method of aortic analysis • Haemodynamic analysis of stent-grafts could improve clinical management and follow-up.

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

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

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

    Pneumothorax (PNX) is the collection of air between parietal and visceral pleura, and collapsed lung develops as a complication of the trapped air. PNX is likely to develop spontaneously in people with risk factors. However, it is mostly seen with blunt or penetrating trauma. Diagnosis is generally confirmed by chest radiography [posteroanterior chest radiography (PACR)]. Chest ultrasound (US) is also a promising technique for the detection of PNX in trauma patients. There is not much literature on the evaluation of blunt thoracic trauma (BTT) and pneumothorax (PNX) in the emergency department (ED). The aim of this study was to investigate the effectiveness of chest US for the diagnosis of PNX in patients presenting to ED with BTT. This study was carried out for a period of nine months in the ED of a university hospital. The chest US of patients was performed by emergency physicians trained in the field. The results were compared with anteroposterior chest radiography and/or CT scan of the chest. The APCR and chest CT results were evaluated by a radiology specialist blind to US findings. The evaluation of the radiology specialist was taken as the gold standard for diagnosis by imaging methods. Clinical follow-up was taken into consideration for the diagnosis of PNX in patients on whom CT scan was not performed. Chest US was performed on all two hundred and twelve patients (144 female and 68 male patients; mean age 45.8) who participated in this study. The supine APCR was performed on two hundred and ten (99%) patients and chest CT was performed on one hundred and twenty (56.6%). Out of the twenty-five (11.8%) diagnosed cases of PNX, 22 (88%) were diagnosed by chest US and 8 were diagnosed by APCR. For the detection of PNX, compared to clinical follow-up and chest CT, the sensitivity of chest US was 88%, specificity 99.5%, positive predictive value 95.7% and negative predictive value 98.4%. Chest US has not superseded supine and standing chest radiography for PNX

    Measures of contraceptive effectiveness combine technology and user-related factors. Observational studies show higher effectiveness of long-acting reversible contraception compared with short-acting reversible contraception. Women who choose long-acting reversible contraception may differ in key ways from women who choose short-acting reversible contraception, and it may be these differences that are responsible for the high effectiveness of long-acting reversible contraception. Wider use of long-acting reversible contraception is recommended, but scientific evidence of acceptability and successful use is lacking in a population that typically opts for short-acting methods. The objective of the study was to reduce bias in measuring contraceptive effectiveness and better isolate the independent role that long-acting reversible contraception has in preventing unintended pregnancy relative to short-acting reversible contraception. We conducted a partially randomized patient preference trial and recruited women aged 18-29 years who were seeking a short-acting method (pills or injectable). Participants who agreed to randomization were assigned to 1 of 2 categories: long-acting reversible contraception or short-acting reversible contraception. Women who declined randomization but agreed to follow-up in the observational cohort chose their preferred method. Under randomization, participants chose a specific method in the category and received it for free, whereas participants in the preference cohort paid for the contraception in their usual fashion. Participants were followed up prospectively to measure primary outcomes of method continuation and unintended pregnancy at 12 months. Kaplan-Meier techniques were used to estimate method continuation probabilities. Intent-to-treat principles were applied after method initiation for comparing incidence of unintended pregnancy. We also measured acceptability in terms of level of happiness with the products. Of the 916

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

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

  14. Nuclear analytical methods: Past, present and future

    The development of nuclear analytical methods as an analytical tool began in 1936 with the publication of the first paper on neutron activation analysis (NAA). This year, 1996, marks the 60th anniversary of that event. This paper attempts to look back at the nuclear analytical methods of the past, to look around and to see where the technology is right now, and finally, to look ahead to try and see where nuclear methods as an analytical technique (or as a group of analytical techniques) will be going in the future. The general areas which the author focuses on are: neutron activation analysis; prompt gamma neutron activation analysis (PGNAA); photon activation analysis (PAA); charged-particle activation analysis (CPAA)

  15. Diagnosis of toxic alcohols: limitations of present methods.

    Methanol, ethylene glycol, diethylene glycol, and propylene glycol intoxications are associated with cellular dysfunction and an increased risk of death. Adverse effects can develop quickly; thus, there is a need for methods for rapidly detecting their presence. To examine the value and limitations of present methods to diagnose patients with possible toxic alcohol exposure. I searched MEDLINE for articles published between 1969 and 2014 using the terms: toxic alcohols, serum osmolality, serum osmol gap, serum anion gap, metabolic acidosis, methanol, ethylene glycol, diethylene glycol, propylene glycol, and fomepizole. Each article was reviewed for additional references. The diagnosis of toxic alcohol exposure is often made on the basis of this history and physical findings along with an increase in the serum osmol and anion gaps. However, an increase in the osmol and/or anion gaps is not always present. Definitive detection in blood requires gas or liquid chromatography, laborious and expensive procedures which are not always available. Newer methods including a qualitative colorimetric test for detection of all alcohols or enzymatic tests for a specific alcohol might allow for more rapid diagnosis. Exposure to toxic alcohols is associated with cellular dysfunction and increased risk of death. Treatment, if initiated early, can markedly improve outcome, but present methods of diagnosis including changes in serum osmol and anion gap, and use of gas or liquid chromatography have important limitations. Development of more rapid and effective tests for detection of these intoxications is essential for optimal care of patients.

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

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

    The maintenance of nutritional status is a serious problem for patients suffering from head and neck cancer. Malnutrition leads to prolongation of hospitalisation and is an important risk factor in the development of postoperative complications and infections. This study was conducted to evaluate the consequences of radiochemotherapy on the nutritional status. Furthermore the timing for initiation of nutritional support was analysed. 23 patients with advanced carcinoma of the head and neck were studied prospectively. The treatment protocol consisted of conventional radiotherapy combined with infusional 5-fluorouracil and mitomycin-C. Anthropological, biochemical and immunological parameters and the Hackl-score were used to define malnutrition. The WHO-criteria and the digital dermascope-system were used for scoring and imaging oral mucositis. The dermascope-camera-system allows diagnosis of early mucosal changes and provides objective information on the patients' oral health. At the time of diagnosis malnutrition was present in some patients. Generally the nutritional status worsened until the beginning of therapy. After three weeks of treatment moderate or severe malnutrition and immunsuppression occurred in most of the patients. Analysis of the Hackl-score revealed an absolute indication for nutritional support in 82.6 %. At the end of treatment nutritional therapy was indicated in 100 % of the patients. Nutritional intervention was initiated too late in the clinical course. Prophylactic nutritional therapy is indicated when radiochemotherapy is planned for patients with advanced head and neck cancer.(author)

After three weeks of treatment moderate or severe malnutrition and immunsuppression occurred in most of the patients. Analysis of the Hackl-score revealed an absolute indication for nutritional support in 82,6 %. At the end of treatment nutritional therapy was indicated in 100 % of the patients. Nutritional intervention was initiated too late in the clinical course. Prophylactic nutritional therapy is indicated when radiochemotherapy is planned for patients with advanced head and neck cancer. (author)

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

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

    2017-06-01

    Full Text Available It is justified that design is an inverse problem, and the optimization is a paradigm. Classes of design problems are proposed and typical obstacles are recognized. Peculiarities of the mechatronic designing are specified as a proof of a particle importance of optimization in the mechatronic design. Two main obstacles of optimization are discussed: a complexity of mathematical models and an uncertainty of the value system, in concrete case. Then a set of non-standard approaches and methods are presented and discussed, illustrated by examples: a fuzzy description, a constraint-based iterative optimization, AHP ranking method and a few MADM functions in Matlab.

  2. Social network analysis: Presenting an underused method for nursing research.

    Science.gov (United States)

    Parnell, James Michael; Robinson, Jennifer C

    2018-06-01

    This paper introduces social network analysis as a versatile method with many applications in nursing research. Social networks have been studied for years in many social science fields. The methods continue to advance but remain unknown to most nursing scholars. Discussion paper. English language and interpreted literature was searched from Ovid Healthstar, CINAHL, PubMed Central, Scopus and hard copy texts from 1965 - 2017. Social network analysis first emerged in nursing literature in 1995 and appears minimally through present day. To convey the versatility and applicability of social network analysis in nursing, hypothetical scenarios are presented. The scenarios are illustrative of three approaches to social network analysis and include key elements of social network research design. The methods of social network analysis are underused in nursing research, primarily because they are unknown to most scholars. However, there is methodological flexibility and epistemological versatility capable of supporting quantitative and qualitative research. The analytic techniques of social network analysis can add new insight into many areas of nursing inquiry, especially those influenced by cultural norms. Furthermore, visualization techniques associated with social network analysis can be used to generate new hypotheses. Social network analysis can potentially uncover findings not accessible through methods commonly used in nursing research. Social networks can be analysed based on individual-level attributes, whole networks and subgroups within networks. Computations derived from social network analysis may stand alone to answer a research question or incorporated as variables into robust statistical models. © 2018 John Wiley & Sons Ltd.

    2014-04-01

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

  4. Using an analytical geometry method to improve tiltmeter data presentation

    Su, W.-J.

    2000-01-01

    The tiltmeter is a useful tool for geologic and geotechnical applications. To obtain full benefit from the tiltmeter, easy and accurate data presentations should be used. Unfortunately, the most commonly used method for tilt data reduction now may yield inaccurate and low-resolution results. This article describes a simple, accurate, and high-resolution approach developed at the Illinois State Geological Survey for data reduction and presentation. The orientation of tiltplates is determined first by using a trigonometric relationship, followed by a matrix transformation, to obtain the true amount of rotation change of the tiltplate at any given time. The mathematical derivations used for the determination and transformation are then coded into an integrated PC application by adapting the capabilities of commercial spreadsheet, database, and graphics software. Examples of data presentation from tiltmeter applications in studies of landfill covers, characterizations of mine subsidence, and investigations of slope stability are also discussed.

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

    Ahmed Al-Imam

    2016-01-01

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

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

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

    Directory of Open Access Journals (Sweden)

    Norm Clothier, MD, M. Kim Marvel, PhD, Courtney S. Cruickshank, MS

    2002-09-01

    Full Text Available Purpose: Despite the associated health consequences, obesity is infrequently documented as a problem in medical charts. The purpose of this study is to determine whether a simple intervention (routine listing of the BMI on the medical chart will increase physician documentation of obesity in the medical record. Methods: Participants were resident physicians in a family medicine residency program. Participants were randomly assigned to either an experimental group or a control group. For experimental group physicians, the Body Mass Index was listed alongside other vital signs of patients seen in an ambulatory setting. Physician documentation of patient obesity was assessed by chart review after patient visits. Documentation was defined as inclusion of obesity on the problem list or in the progress note. Results: The intervention did not significantly increase the rate of documentation of obesity in the medical chart. Several reasons for the lack of change are explored, including the difficulty of treating obesity successfully.

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

The appointed subject for the very first one of them was Radio and the invited scholar, Eduardo Vicente, professor at the Graduate Course in Audiovisual and at the Postgraduate Program in Audiovisual Media and Processes of the School of Communication and Arts of the University of São Paulo (ECA-USP. Entitled Radio Beyond Borders the dossier gathers six articles and the intention of reuniting works on the perspectives of usage of such media as much as on the new possibilities of aesthetical experimenting being build up for it, especially considering the new digital technologies and technological convergences. It also intends to present works with original theoretical approach and original reflections able to reset the way we look at what is today already a centennial media. Having broadened the meaning of “beyond borders”, four foreign authors were invited to join the dossier. This is the first time they are being published in this country and so, in all cases, the articles where either written or translated into Portuguese.The dossier begins with “Radio is dead…Long live to the sound”, which is the transcription of a thought provoking lecture given by Armand Balsebre (Autonomous University of Barcelona – one of the most influential authors in the world on the Radio study field. It addresses the challenges such media is to face so that it can become “a new sound media, in the context of a new soundscape or sound-sphere, for the new listeners”.

    Full Text Available The questions of quality presentations to the scientific lectures are very important and modern. Сomputer presentations help to clearly give the necessary information, to enrich the text, to focus on the essentials. An effect of the performance on the audience is the most important thing in the presentation. The scientific presentation must be logically constructed, consistent, concise and vivid. There is the main rule for successful presentations: to tell the truth as a story with slides (pictures. Creating a presentation requires serious intellectual work and preparation that contains the following steps: 1 to estimate the audience and purpose; 2 to reflect a structure and content; 3 to develop a plan; 4 to write the text and prepare the slides; 5 to rehearse the performance. Slides should supplement or summarize the contents of the speech or its parts, but not duplicate it. Effective use of slides helps us understand that they have the maximum impact on the audience. It should also follow the rules of creating slides. Content of slides must comply with the performance. Information in slides should be presented logically, evenly and dosed. Basic facts and ideas are given in the final part. Students or young scientists should consider the design of the presentation as balanced, contrasting and relevant. Following the laws of composition, color, ergonomics is the required condition to accomplish this task. The presentation is not only the slides, it is the combination of many elements, the foremost of which is the speaker. Any presentation must conform to basic principles of psychology.

    To verify the frequency of self-reported medical conditions and pain areas in orofacial pain patients, comparing them with patients from the routine dental care. Data were collected from archives of the Orofacial Pain Clinic (Group A, n=319) and of the routine dental care clinics (Group B, n=84) at Faculdade de Odontologia de Araraquara, São Paulo, in Brazil. All individuals answered a standardized clinical questionnaire and completed a body map indicating their pain areas. The Mann-Whitney's test demonstrated that Group A presented a higher mean number of medical reports than Group B (p=0.004). In both groups, Pearson's correlation test showed that the highest frequencies of medical conditions were positively correlated to highest frequencies of painful areas (0.478, p=0.001 and 0.246, p=0.000, respectively). Group A tended to report more medical conditions and there was a positive correlation between the number of medical conditions and the one of pain areas for both groups.

    Uranium analyses of raw water, intermediate stage, and treated water samples from 20 municipal water treatment plants indicated that the present treatment practices were not effective in removing uranium from raw waters when the influent concentration was in the range of 0.1 to 16 μg/L uranium. Laboratory batch tests revealed that the water softening and coagulant chemicals commonly used were able to remove more than 90% of the dissolved uranium ( < 100 μg/L) in waters if an optimum pH and dosage were provided. Absorbents, titanium oxide and activated charcoal, were also effective in uranium removal under specific conditions. Strong base anion exchange resin was the most efficient uranium adsorbent, and an anion exchange column is a recommended option for the treatment of private well waters containing uranium at higher than desirable levels

    Recent rapid development of next generation sequencing (NGS) technologies provided significant impact into genomics field of study enabling implementation of many de novo sequencing projects of new species which was previously confined by technological costs. Along with advancement of NGS there was need for adjustment in assembly programs. New algorithms must cope with massive amounts of data computation in reasonable time limits and processing power and hardware is also an important factor. In this paper, we address the issue of assembly pipeline for de novo genome assembly provided by programs presently available for scientist both as commercial and as open - source software. The implementation of four different approaches - Greedy, Overlap - Layout - Consensus (OLC), De Bruijn and Integrated resulting in variation of performance is the main focus of our discussion with additional insight into issue of short and long reads correction.

  4. Statistical methods in nuclear material accountancy: Past, present and future

    1983-01-01

    The analysis of nuclear material inventory data is motivated by the desire to detect any loss or diversion of nuclear material, insofar as such detection may be feasible by statistical analysis of repeated inventory and throughput measurements. The early regulations, which laid down the specifications for the analysis of inventory data, were framed without acknowledging the essentially sequential nature of the data. It is the broad aim of this paper to discuss the historical nature of statistical analysis of inventory data including an evaluation of why statistical methods should be required at all. If it is accepted that statistical techniques are required, then two main areas require extensive discussion. First, it is important to assess the extent to which stated safeguards aims can be met in practice. Second, there is a vital need for reassessment of the statistical techniques which have been proposed for use in nuclear material accountancy. Part of this reassessment must involve a reconciliation of the apparent differences in philosophy shown by statisticians; but, in addition, the techniques themselves need comparative study to see to what extent they are capable of meeting realistic safeguards aims. This paper contains a brief review of techniques with an attempt to compare and contrast the approaches. It will be suggested that much current research is following closely similar lines, and that national and international bodies should encourage collaborative research and practical in-plant implementations. The techniques proposed require credibility and power; but at this point in time statisticians require credibility and a greater level of unanimity in their approach. A way ahead is proposed based on a clear specification of realistic safeguards aims, and a development of a unified statistical approach with encouragement for the performance of joint research.

    Full Text Available Aim: to estimate the influence of punctural millimeter wave therapy on clinical presentation. Material and methods. This study includes 102 patients with essential hypertension the I and II stage. Patients were divided into three equal groups depending on the method of treatment: some of them received procedures of punctural millimeter wave therapy, some of them received these procedures as the "placebo" and those who had not received specified procedures. Dynamics of clinical symptomatology and condition of eye bottom vessels was estimated. It was shown that addition of punctural millimeter wave therapy in complex therapy of patients with essential hypertension promotes the expressed regress of clinical symptomatology and state normalization the retinal vessels at these patients. Results. Addition of punctural millimeter wave therapy into the complex therapy was shown to lead to pronounced regress of clinical symptoms. Conclusion. The received results allow to recommend this method to be used in clinical practice for treating patients with essential hypertension.

    A 37-year-old man presented with worsening headache, vomiting, and right-sided weakness over the last few weeks. A head computed tomography showed a left hemispheric posterior medial parietal lobe lesion with surrounding edema. Further imaging with magnetic resonance imaging showed multiple enhancing mass lesions. The largest lesion measured 2.4 cm within the left occipital parietal region (Figure A and B). Laboratory data showed reactive HIV antibodies, confirmed by Western blot. An absolute CD4 count was 22 cells/μL. Other laboratory test results showed low sodium, thyrotropin, FT4, FT3, cortisol levels, corticotropin, luteinizing hormone, and testosterone. Based on these findings, the brain lesions were believed to be causing his panhypopituitarism. A brain biopsy confirmed the presence of Toxoplasma gondii by polymerase chain reaction. The patient was started on pyrimethamine and clindamycin for toxoplasmosis treatment, and azithromycin and sulfamethoxazole/trimethoprime for appropriate prophylaxis. He was also started on hormone supplementation. His symptoms were completely resolved at the time of discharge.

    Full Text Available Aim: The aim of this study was to investigate the rate of new-onset diabetes mellitus (DM in patients presenting to our emergency department with diabetic ketoacidosis. Methods: We retrospectively evaluated hospital records of patients who presented to the Emergency Department at Istanbul Goztepe Research and Training Hospital between 01 April 2009 and 01 April 2011 and were diagnosed with diabetic ketoacidosis. 57 patients having complete clinical data were included in the study. Results: 45.6%of patients had type 1 DM, 33.3%- type 2 DM, and 21%of them were with new-onset DM. No statistically significant difference was found between type 1 DM, type 2 DM and new-onset DM patients with respect to arterial blood pH and HCO3 levels and serum sodium, potassium and plasma glucose levels at presentation as well as time of presentation (p>0.05, while HbA1c levels showed statistically significant difference in new-onset DM patients. Conclusion: No statistically significant difference was found between types of DM in patients diagnosed with diabetic ketoacidosis except for precipitating factors, age and HbA1c. Detecting high blood glucose levels in patients presenting to emergency room for reasons other than DM is not a rare condition. Cautious evaluation and recognition of these patients in emergency room for the possibility of undiagnosed DM is important for prevention of future diabetic ketoacidosis episodes.

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

    Full Text Available Co-secretion of growth hormone (GH and prolactin (PRL from a single pituitary adenoma is common. In fact, up to 25% of patients with acromegaly may have PRL co-secretion. The prevalence of acromegaly among patients with a newly diagnosed prolactinoma is unknown. Given the possibility of mixed GH and PRL co-secretion, the current recommendation is to obtain an insulin-like growth factor-1 (IGF-1 in patients with prolactinoma at the initial diagnosis. Long-term follow-up of IGF-1 is not routinely done. Here, we report two cases of well-controlled prolactinoma on dopamine agonists with the development of acromegaly 10–20 years after the initial diagnoses. In both patients, a mixed PRL/GH-cosecreting adenoma was confirmed on the pathology examination after transsphenoidal surgery (TSS. Therefore, periodic routine measurements of IGF-1 should be considered regardless of the duration and biochemical control of prolactinoma.

    Coeliac disease is characterised by an increased mortality mostly due to its complications. To study the risk of developing complications according to clinical presentation and age at diagnosis, a combined retrospective-prospective longitudinal study was performed in three Italian centres. Incidence of complications and mortality rates were calculated using type and age at diagnosis of coeliac disease, sex, and centre of diagnosis as predictors. Patients referred after being found to suffer from coeliac disease elsewhere were excluded. Between 01/1999 and 06/2015, 2225 adult coeliac patients were directly diagnosed in our centres. 17 of them developed a complication and 29 died. In patients older than 60 years at diagnosis of coeliac disease, the risk of complication is 18 times higher than in patients diagnosed at 18-40 years and 9 times higher than in patients diagnosed at 40-60 years. Classical presentation increases the risk of complications by 7 times compared to non-classical presentation; in asymptomatic patients the risk of complication is virtually absent. The risk of developing complications in coeliac patients is linked to age at diagnosis of coeliac disease and type of clinical presentation. Follow-up methods of coeliac patients should be tailored according to these parameters. Copyright © 2017. Published by Elsevier Ltd.

    1997-01-01

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

    Autism has been reported in untreated patients with phenylketonuria. The authors aimed to explore autism in 15 Tunisian and 4 Algerian phenylketonuria patients, and report their clinical, biochemical and molecular peculiarities. The Childhood Autism Rating Scale and the Autism Diagnostic Interview-Revised were used for the diagnosis of autism. Five exons of phenylalanine hydroxylase gene (7, 6, 10, 11, and 5) were amplified by polymerase chain reaction and directly sequenced. Among these patients, 15 were suffering from autism at the time of evaluation. Six mutations were identified: p.E280K, p.G352Vfs, IVS10nt11, p.I224T, p.R261Q, and p.R252W. There was no correlation between autism and mutations affecting the phenylalanine hydroxylase gene, but the age of diet onset was the determining factor in autistic symptoms' evolution. © The Author(s) 2016.

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

    Full Text Available We report our experience with the diagnosis and treatment of 60 patients with American cutaneous leishmaniasis. They were infected in Panama (55, Brazil (4 or Colombia (I. Among 35 patients with a 3 week exposure in Panama, the mean maximum incubation period was 33 days (range 4-81 days. Diagnosis was delayed an average of 93 days after onset of skin lesions, due to the patient's delay in seeking medical attention (31 days, medical personnel's delay in considering the diagnosis (45 days, and the laboratory's delay in confirming the diagnosis (17 days. Forty-four patients (73% developed ulcers typical of cutaneous leishmaniasis. Sixteen additional patients (27% had atypical macular, papular, squamous, verrucous or acneiform skin lesions that were diagnosed only because leishmanial cultures were obtained. Of the 59 patients treated with pentavalent antimonial drugs, only 34 (58% were cured after the first course of treatment. Lesions which were at least 2 cm in diameter, ulcerated, or caused by Leishmania braziliensis were less likely to be cured after a single course of treatment than were lesions smaller than 2 cm, nonulcerated or caused by Leishmania mexicana or Leishmania donovani.Relatamos nossa experiência em 60 pacientes com leishmaniose tegumentar americana diagnosticada e tratada entre 1977 e 1982.

    The percutaneous treatment of pericardial effusion resulting in cardiac tamponade has undergone an evolution in recent years with the use of less invasive drainage techniques in selected cases. To determine optimal therapy modalities for oncology patients with malignant pericardial tamponade (MPT), the authors review their institutional experience with percutaneous needle puncture routes, means of imaging-guided drainage and percutaneous management of the pericardial fluid effusion (pericardial sclerosis and balloon pericardiotomy). Advantages and limits of the percutaneous techniques will be compared to the surgical treatment. (orig.)

    Objective Invasive pulmonary aspergillosis (IPA) is a severe and often lethal infection. The possible risk factors, clinical presentation, and treatment of patients with simultaneous liver failure and IPA have received little attention in previous studies. The aim of this study was to investigate the epidemiology of IPA in patients with liver failure in an effort to reduce patient mortality. Methods The patients with liver failure (including acute liver failure , sub-acute liver failure , acute-on-chronic liver failure and chronic liver failure) were recruited from 2011 to 2016. The clinical data of these patients were retrieved for the study. Results In total, 1077 patients with liver failure were included in this study. Of the 1077 patients, 53 (4.9%) had IPA. Forty-four (83%) patients with IPA died. Independent risk factors for IPA were male sex (hazard ratio [HR] = 2.542), hepatorenal syndrome (HR = 2.463), antibiotic use (HR = 4.631), and steroid exposure (HR = 18.615). Conclusions IPA is a fatal complication in patients with liver failure. Male sex, hepatorenal syndrome, antibiotic use, and steroid exposure were independent risk factors for IPA. When patients with liver failure have these risk factors and symptoms of pneumonia such as cough or hemoptysis, clinicians should be cautious about the possibility of IPA.

    Full Text Available Objectives: Carbon monoxide is a potentially fatal form of poisoning. The exact incidence is unclear, due to cases being undiagnosed or reported as fewer than the real number. Hyperbaric oxygen therapy (HBOT is of proven efficacy in the treatment of CO intoxication.The purpose of this study was to describe the general characteristics of carbon monoxide (CO intoxications presenting to the emergency department and to investigate troponin I values and the effectiveness of hyperbaric oxygen therapy (HBOT in these patients. Material and methods: Patients presenting to the emergency department with CO intoxication over one year and patients with such intoxications receiving HBOT were examined retrospectively. Results: One hundred seventy-one patients were included; 140 (81.9% were poisoned by stoves, 18 (10.5% by hot water boilers and 10 in (5.8% by fires. COHb levels were normal in 49 of the 163 patients whose values were investigated, and were elevated in 114 patients. Mean COHb value was 16.6. Troponin I values were investigated in 112 patients. These were normal in 86 patients and elevated in 26. Mean troponin I value was 0.38 ng/ml. One hundred twenty-three of the 171 patients in the study were discharged in a healthy condition after receiving normobaric oxygen therapy, while 48 patients received HBOT. Forty-two (87.5% of the patients receiving HBOT were discharged in a healthy condition while sequelae persisted in five (10.4%. One patient died after 15 session of HBOT. Conclusion: Although elevated carboxyhemoglobin confirms diagnosis of CO intoxication, normal levels do not exclude it. Troponin I levels may rise in CO intoxication. No significant relation was observed between carboxyhemoglobin and receipt of HBOT. A significant correlation was seen, however, between troponin I levels and receipt of HBOT.

OBJECTIVE To study the various aetiologies and clinical presentations of patients presenting with sexual precocity to a tertiary care hospital. DESIGN Cross sectional study. MATERIAL AND METHODS We collected and analysed the clinical data including hormonal status of 24 consecutive patients who presented to our department from January 2014 to December 2015 for evaluation of sexual precocity. RESULTS Most of the patients presenting to us had evidence of precocious puberty (n=16, followed by premature adrenarche (n=5 and premature thelarche (n=3 respectively. The females outnumbered males in our study (68.75% of total cases. Females presenting with central precocious puberty had no appreciable cause (idiopathic in majority (85.72% of cases. While, males presenting with central precocious puberty had an organic cause (60% in majority of cases. CONCLUSIONS Precocious puberty is more common among females as compared to males. Organic lesion must be ruled out in all patients presenting with central precocious puberty especially in males.

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

    Recently, the attendance rate for breast screening has been increasing in Japan. However, little is known about how to conduct effective breast cancer screening, especially for patients with mental disability. The purpose of this study was to clarify the present status of breast cancer screening for severely disabled patients. Breast screening was performed for 160 disabled patients by physical examination and ultrasound from 2002 to 2005. The patients included 158 women and two men, with an average age of 59 years old. Ten disabled patients (10/160; 6.3%) showed abnormal findings on physical examination and four (4/160; 2.5%) showed probably benign findings by ultrasound examination. Mammography (MMG) screening was performed for only 33 patients (33/160; 21%), one of whom needed further examination. One lesion was diagnosed as breast cancer (1/160; 0.63%). Breast ultrasound is useful for severely disabled patients because it is painless, easy and rapid to perform. On the other hand, it is sometimes difficult for such patients to participate in MMG screening because of their inability to adapt to the examination. Therefore, some psychological method, for example operant conditioning, will be necessary for breast screening of patients with severe mental disability. (author)

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

    Full Text Available BACKGROUND: Keeping abdominal surgery patients warm is common and warming methods are needed in power outages during natural disasters. We aimed to evaluate the efficacy of low-cost, low-power warming methods for maintaining normothermia in abdominal surgery patients. METHODS: Patients (n = 160 scheduled for elective abdominal surgery were included in this prospective clinical study. Five warming methods were applied: heated blood transfusion/fluid infusion vs. unheated; wrapping patients vs. not wrapping; applying moist dressings, heated or not; surgical field rinse heated or not; and applying heating blankets or not. Patients' nasopharyngeal and rectal temperatures were recorded to evaluate warming efficacy. Significant differences were found in mean temperatures of warmed patients compared to those not warmed. RESULTS: When we compared temperatures of abdominal surgery patient groups receiving three specific warming methods with temperatures of control groups not receiving these methods, significant differences were revealed in temperatures maintained during the surgeries between the warmed groups and controls. DISCUSSION: The value of maintaining normothermia in patients undergoing abdominal surgery under general anesthesia is accepted. Three effective economical and practically applicable warming methods are combined body wrapping and heating blanket; combined body wrapping, heated moist dressings, and heating blanket; combined body wrapping, heated moist dressings, and warmed surgical rinse fluid, with or without heating blanket. These methods are practically applicable when low-cost method is indeed needed.

    Full Text Available Introduction. Patients with severe combined immunodeficiency (SCID may present with residual circulating T cells. While all cells are functionally deficient, resulting in high susceptibility to infections, only some of these cells are causing autoimmune symptoms. Methods. Here we compared T-cell functions including the number of circulating CD3+ T cells, in vitro responses to mitogens, T-cell receptor (TCR repertoire, TCR excision circles (TREC levels, and regulatory T cells (Tregs enumeration in several immunodeficinecy subtypes, clinically presenting with nonreactive residual cells (MHC-II deficiency or reactive cells. The latter includes patients with autoreactive clonal expanded T cell and patients with alloreactive transplacentally maternal T cells. Results. MHC-II deficient patients had slightly reduced T-cell function, normal TRECs, TCR repertoires, and normal Tregs enumeration. In contrast, patients with reactive T cells exhibited poor T-cell differentiation and activity. While the autoreactive cells displayed significantly reduced Tregs numbers, the alloreactive transplacentally acquired maternal lymphocytes had high functional Tregs. Conclusion. SCID patients presenting with circulating T cells show different patterns of T-cell activity and regulatory T cells enumeration that dictates the immunodeficient and autoimmune manifestations. We suggest that a high-tolerance capacity of the alloreactive transplacentally acquired maternal lymphocytes represents a toleration advantage, yet still associated with severe immunodeficiency.

    Purpose of Study: The purpose is to evaluate the findings and utility of esophageal transit scintigraphy (ETS) and gastroesophageal reflux scintigraphy (GES) in patients presenting with upper respiratory tract (URT) symptoms suspected to be due to gastroesophageal reflux (GER) disease. Materials and Methods: Thirty patients aged between 19 and 60 years underwent nasopharyngolaryngoscopy (NPL), ETS, and GES. Correlation between GER, esophageal motility, and NPL was evaluated. Inclusion criteria include patients with recurrent URT symptoms such as chronic dry cough/hoarseness of voice and itching/foreign body sensation in throat. Those with typical gastrointestinal (GI) symptoms of GER, URT symptoms relieved by antibiotics, surgical intervention in abdomen, cardiac/hepatobiliary diseases, etc. were excluded from the study. Results: Significant correlation was found between GER and NPL in 28/30 patients. More the grade of reflux, more severe was the NPL findings. Two patients with Grade II reflux had normal NPL suggesting structural inflammatory changes due to acidic pH of refluxate which have not yet manifested or symptoms could be due to nonacid refluxate. Incidence of esophageal motility disorder was statistically significant in patients with GER disease (GERD). Patients who had symptoms, but no demonstrable GER showed delayed ET in supine position suggesting the presence of esophageal motility disorder even before GERD. Conclusion: GES demonstrated GER in patients presenting with URT symptoms without typical GI symptoms. ETS showed coexistence of esophageal motility disorder in most patients presenting with URT symptoms even without an associated reflux disease. We hypothesize that primary abnormal esophageal motility leads to delayed esophageal clearance and consequently to URT symptoms. Addition of ETS to GES is easily feasible with no significant additional cost, time, or radiation burden. PMID:29430111

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

    Full Text Available Abstract Background Legionella species cause severe forms of pneumonia with high mortality and complication rates. Accurate clinical predictors to assess the likelihood of Legionella community-acquired pneumonia (CAP in patients presenting to the emergency department are lacking. Methods We retrospectively compared clinical and laboratory data of 82 consecutive patients with Legionella CAP with 368 consecutive patients with non-Legionella CAP included in two studies at the same institution. Results In multivariate logistic regression analysis we identified six parameters, namely high body temperature (OR 1.67, p Legionella CAP. Using optimal cut off values of these six parameters, we calculated a diagnostic score for Legionella CAP. The median score was significantly higher in Legionella CAP as compared to patients without Legionella (4 (IQR 3–4 vs 2 (IQR 1–2, p Legionella pneumonia. Conversely, of the 73 patients (16% with ≥4 points, 66% of patients had Legionella CAP. Conclusion Six clinical and laboratory parameters embedded in a simple diagnostic score accurately identified patients with Legionella CAP. If validated in future studies, this score might aid in the management of suspected Legionella CAP.

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

    Full Text Available Keratinocyte skin cancers, including basal cell carcinoma (BCC and squamous cell carcinoma (SCC, are the most common cancer occurring in people with fair skin, worldwide. Despite all known triggers, several suggested contributors are still investigated. We will focus our attention on the personal history of previous cancers and radiation exposure as occupational risk factors, as in the presented case. We report a patient, with multiple BCCs, and subsequent occurrence of a SCC on photo-exposed area of the face, as we want to emphasize the importance of strict following up of these patients, regarding the risk for developing new tumors in short periods of time, no matter if the triggering exposure factor is known from the history, or not.  Although keratinocytes tumours are associated with the low mortality rate, we focus the attention on the fact, that the history of non-melanoma skin cancer is associated with increased mortality.

    To determine the frequency of positive computed tomographic (CT)scan findings in patients presenting at PNS Shifa Hospital Karachi with chief complaint of headache without focal neurological signs. Study Design: Cross sectional descriptive study. Place and Duration of Study: The study was conducted at the Radiology department, PNS Shifa Hospital Karachi from Dec 2011 to Jun 2012. Patients and Methods: This cross-sectional descriptive study included referred patients with complaint of headache of one month duration or more without focal neurological signs. No gender restriction was considered and patients of age more than 14 years were included. Patients with headache due to other known clinical disorders such as intracranial neoplasm and stroke were excluded. Patients with focal neurological signs such as hemiparesis, cerebellar signs and cranial nerve palsies were also excluded from the study. A total of 105 patients were included in the study through non probability consecutive sampling. Informed written consent was taken from the patients by explaining all the risks and benefits of the study and use of data for research and publication. Plain CT scan brain was done by trained CT technician and reporting of CT scan was done by consultant radiologist. CT scan was done on Toshiba Scanner Aquilion-64 CT Scan machine. The imaging protocol consisted of appropriately angled continuous 5mm thick axial slices for the posterior fossa and 10 mm thick slices for the rest of brain from the base of skull to the vertex. Data was collected through a specially structured proforma. Confidentiality of the patients record was maintained. Results: Majority of the patients were between 31-40 years of age i.e. 29.52 percent (n=31) and mean and SD was calculated as 34.24 +- 8.72 years, 54.29 percent (n=57) females and 45.71 percent (n=48) male patients, frequency of positive CT scan findings in patients with chief complaint of headache without focal neurological signs was recorded as

    A medical student's ability to present a case history is a critical skill that is difficult to teach. Case histories presented without theatrical engagement may fail to catch the attention of their intended recipients. More engaging presentations incorporate 'stage presence', eye contact, vocal inflection, interesting detail and succinct, well organised performances. They convey stories effectively without wasting time. To address the didactic challenge for instructing future doctors in how to 'act', the Mayo Medical School and The Mayo Clinic Center for Humanities in Medicine partnered with the Guthrie Theater to pilot the programme 'Telling the Patient's Story'. Guthrie teaching artists taught storytelling skills to medical students through improvisation, writing, movement and acting exercises. Mayo Clinic doctors participated and provided students with feedback on presentations and stories from their own experiences in patient care. The course's primary objective was to build students' confidence and expertise in storytelling. These skills were then applied to presenting cases and communicating with patients in a fresher, more engaging way. This paper outlines the instructional activities as aligned with course objectives. Progress was tracked by comparing pre-course and post-course surveys from the seven participating students. All agreed that the theatrical techniques were effective teaching methods. Moreover, this project can serve as an innovative model for how arts and humanities professionals can be incorporated for teaching and professional development initiatives at all levels of medical education.

    Full Text Available Background. Situs inversus viscerum totalis (reciprocally reversed position of internal organs is a rare case with genetic predisposition, inherited autosomnously recessive. The presented case involves an older patient with complete transposition of internal organs having acute calculous cholecystitis, which was successfully performed the laparoscopic cholecystectomy. Whilst the production of biliary stones in a case of transposed internal organs is very rare, it may well represent a diagnostic problem. It is not, however, the contraindication for laparoscopic surgery.Patients and methods. The case presents a 64-year-old patient, whose persistent biliary colic trouble eventually resulted in acute cholecystitis. Following routine diagnostics, a laparoscopic cholecystectomy was performed and the patient was released in domestic care after three day hospitalization.Conclusions. The laparoscopic cholecystectomy may also be safely performed in a patient with reciprocal transposition of all internal organs, but it is imperative to consider the fact that the extra-hepatic anatomy of gall bladder and vascular system is the mirror image of normal, right-hand positioned liver.

    Full Text Available Objective:Hoarding is commonly defined as the acquisition ofand failure to discard possessions of little use or value, and isincluded as a symptom in the diagnostic criteria for obsessivecompulsive personality disorder (OCPD and obsessivecompulsive disorder (OCD. However, it has also beenobserved in other clinical syndromes including schizophrenia.This study was conducted to investigate the prevalence andclinical presentation of hoarding behaviour in schizophreniaamong Xhosa patients.Method:The sample consisted of 102 patients, recruited aspart of a larger genetic study in the Cape Town metropolebetween November 2004 and January 2005, diagnosed withschizophrenia or schizoaffective disorders according to theDiagnostic and Statistical Manual of Mental Disorders(DSM-IVcriteria. They were screened for clinically significant hoardingsymptoms. If these were present, additional information onthe phenomenology was obtained by means of a structuredquestionnaire. The Mini International Neuropsychiatric Interview(MINI (screen and full version, the Yale Brown ObsessiveCompulsive Scale (Y-BOCS Checklist, Y-BOCS, Clutter ImageRating Scale (CIRS and a structured questionnaire on hoardingwere administered.Results:Only four patients with schizophrenia were classifiedas hoarders. Although their clinical presentation resembled thatof hoarders described elsewhere in the literature, they had lowY-BOCS scores and did not report other obsessive-compulsivesymptoms.Conclusion:Our results suggest that hoarding behaviour isnot common in Xhosa patients with schizophrenia. Furtherinvestigation of protective factors for hoarding behaviour in theXhosa population is warranted.

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

    Full Text Available BACKGROUND Lung cancer is the most common cancer worldwide since 1985, both in terms of incidence and mortality. Globally, lung cancer is the largest contributor to new cancer diagnoses and cancer-related deaths. The aim of the study is to study the clinical, radiological and pathological features of patients diagnosed with lung carcinoma. MATERIALS AND METHODS This observational and cross-sectional study was conducted at Himalayan Institute of Medical Sciences (HIMS, which is a large tertiary centre of Uttarakhand on 77 patients of proven lung carcinoma diagnosed over a period of February 2015 to March 2016. The clinical history of the patients was recorded in detail along with the radiological and pathological findings. Ethical clearance certificate was obtained from the ethical committee. RESULTS The study included a total of 77 patients of proven lung carcinoma. Out of the total patients, 70 were males and 7 were females. Cough was the most common symptom. Smoking was the commonest addiction (89.61% in the patients. Non-small cell carcinoma was seen in 59 patients while small cell carcinoma was seen in 23.38% of the cases. Amongst the total patients of non-small cell carcinoma, the maximum number of patients had squamous cell carcinoma (56%. CONCLUSION This study showed that smoking is a principle risk factor in causation of lung carcinoma. Lung cancer should be suspected in an old person presenting with cough and other symptoms such as malaise, weight loss etc. Squamous cell carcinoma is still the most common histological type of lung cancer in India.

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

  13. A practical tip to engage the left main coronary artery in patients presenting with aortic aneurysms

    2017-09-01

    Full Text Available Coronary angiography in patients presenting with ascending aortic aneurysms can be challenging since standard catheters may fail to reach the left main coronary artery. A widely accepted approach is the mother-in-child catheter technique whereby a catheter with a smaller diameter is telescoped through one with a bigger diameter, a procedure that helps to lengthen the catheter. However, this technique is associated with several disadvantages such as thrombus formation within the catheters, inadvertent damage to the left main ostium, and the necessity of manipulation, which the operator may not be familiar with. Therefore, in our case we present a method, which involves the application of a regular Judkins Right 4 catheter for left main engagement. We propose that this method can be safely attempted prior to using telescoping techniques.

    Full Text Available Objectives: Our study aimed to analyze the clinical presentation, management, and outcome of renal angiomyolipoma patients incidentally detected upon computed tomography (CT examination. Methods: Between 2004 and 2008, all patients who underwent abdominal CT examination for any reason at the radiology department at Hamad General Hospital, Qatar were retrospectively reviewed. The diagnosis of renal angiomyolipoma was based on abdominal CT evaluation. Angiomyolipoma patients were followed-up by CT evaluation as per standard care for three years to observe any change in size and outcome. Results: A total of 13,115 patients were screened, of which 56 (40 females and 16 males had renal angiomyolipoma. The mean age of patients was 52±13 years with 46% Qatar nationals. The majority (95% of cases had unilateral tumors (52% right-sided and 43% left-sided. Twenty-six cases showed increase in tumor size and the median increase was 0.5cm (0.1–3.6. Surgical intervention was required in four (7% cases with tumor size ≥4cm. The overall mortality on follow-up was 7%. The cause of death included metastasis, renal failure, hepatic failure and mesenteric thromboembolism. Conclusion: Renal angiomyolipoma is an uncommon benign tumor with an overall prevalence of 0.4% in Qatar. It has characteristic clinical features and its recognition is often challenging for proper clinical diagnosis and treatment in asymptomatic patients. Asymptomatic patients need regular radiological surveillance. In contrast, surgical interventions are mainly required in symptomatic patients with increased tumor size (≥4cm. Timely diagnosis and treatment is necessary to avoid complications such retroperitoneal hemorrhage and renal impairment.

    Full Text Available Abstract Background Idiopathic membranous nephropathy (IMN is one of the most common causes of primary nephrotic syndrome in adults. However, it is a relatively rare entity in the pediatric population and there is a paucity of data about the incidence, prognosis, and optimal treatment of IMN in children and adolescents. We conducted this study to evaluate pediatric patients with IMN in order to clarify the presentation, response to therapy, and clinical outcome. Methods A retrospective chart review was performed on patients identified with biopsy-proven IMN between 1988–2005. Patients with systemic lupus erythematosus or hepatitis-related lesions were excluded. The following data were tabulated: age, gender, ethnicity, presenting clinical and laboratory findings, proteinuria in a first morning urine specimen, estimated glomerular filtration rate (GFRe, histopathology, type and duration of treatment, and clinical status at final evaluation. Results 13 cases of IMN were identified out of 460 renal biopsies performed for evaluation of primary kidney disease during the study interval. Mean age was 9.6 ± 4.6, gender 6 M:7 F, ethnicity 8 W:2 B:3 H. At the initial visit hematuria was present in 9 patients, edema in 5, nephrotic-range proteinuria in 5, and hypertension in 3. Mean urinary protein:creatinine ratio 3.3 ± 2.5 and all patients had a normal GFRe. Classic glomerular findings of IMN were seen in all renal specimens, with concomitant interstitial changes in 2 cases. Treatment included an angiotensin converting enzyme inhibitor or angiotensin receptor blocker in 11 cases. Most patients were also given immunosuppressive medications – prednisone in 10, a calcineurin inhibitor in 5, and mycophenolate mofetil or azathioprine in 3 patients. At the last follow-up, 42 ± 35 months after the diagnostic biopsy, 7 children were hypertensive and the urine protein:creatinine ratio was 2.3 ± 3.1. The mean GFRe was 127 ± 57 mL/min/m2.

    Objectives: to determine the pattern of clinical manifestations in patients with hypothyroidism and to document the clinical state, the laboratory findings and the effect of therapy on those who restrict themselves to the long term medication and follow up. Design: a prospective study on all patients in whom a clinical suspicious of being hypothyroidism,this was during a period from the first of june 1997 to the end of december 1998 (18 months). Subjects: the study population comprised two groups of patients: a) patients presenting for the first time (n:20). b) patients previously known to be hypothyroidism but stopped the medication for a while from 6 months up to one year or more (n:16). Methods: data was collected through a questionnaire detailing the medical history, medical examination and the laboratory investigations which were performed. Results: hypothyroidism is a disease of female although it's rare but can be encountered, the diagnosis is delayed because of the wide range of symptoms, the commonest were fatigue (88.9%), myalgia (75%), hoarseness of voice (72.2%), dry skin (63.9%), these patients may present with constipation (44.4%) or to the gyne because of menorrhagia (47.2%),or to the psychiatry because of change in mood (41.7%) signs such as delayed relaxation of the knee jerk (83.3%),proximal myopathy (38.9%), perorbital swelling (50%) or loss of eye brows (27.8%) can help in the diagnosis. Conclusion: hypothyroidism is rare in the Sudan, for the diagnosis not to be delayed one should be familiar with the different manifestations in order to be able to elicit appropriate signs. The treatment is satisfactory, responsive to thyroxine which should be life long therapy

    Objective: To determine the frequency of clinopathological characteristics of systemic lupus erythematosus (SLE) patients presenting to Military Hospital (MH) Rawalpindi. Study Design: Descriptive cross sectional study. Place and Duration of Study: The study was carried out at MH Rawalpindi, from Jan 2011 to Dec 2013. Material and Methods: All patients presenting to Rheumatology department, MH Rawalpindi with a diagnosis of SLE were included in this study. Presenting features, clinical profile and laboratory parameters of patients were recorded. Results: A total of 76 patients were included in this study, 70 (92.1%) were females and 6 (7.9%) male patients with female- male ratio of 11.6:1. Mean age at presentation was 33 ± 8.31 years. Seventy two patients (94.7%) were anti nuclear antibody (ANA) positive, 63 (83%) were positive for anti-double stranded deoxyribonucleic acid (anti-dsDNA) antibody and 6 (7.9%) were anti Smith positive. Seventy (92.1%) patients had musculoskeletal symptoms, 65 patients (85.5%) had fever, 36 (47.4%) patients had cutaneous symptoms, and 20 patients (26.3%) had oral ulcers. About 13 patients (17.1%) had alopecia and 15 patients (19.7%) had serositis. Forty two patients (55.3%) had nephritis, 20 patients (26.3%) had lupus cerebritis, 57 patients (75%) had hematological involvement, 9 patients (11.83%) had pulmonary involvement, 8 patients (10.5%) had rheumatoid arthritis (RA) factor positive and 7 patients (9.2%) had overlap syndrome. Conclusion: Renal and hematological involvement was more common in this study population while mucocutaneous features and neuropsychiatric features were comparable to many local studies with exception to that of Lahore based study that showed much higher percentage of these features. These results reflect the need to have a high index of suspicion for kidney and hematological involvement in SLE patients. (author)

    Provided herein are methods for selectively detecting an alkyne-presenting molecule in a sample and related detection reagents, compositions, methods and systems. The methods include contacting a detection reagent with the sample for a time and under a condition to allow binding of the detection reagent to the one or more alkyne-presenting molecules possibly present in the matrix to the detection reagent. The detection reagent includes an organic label moiety presenting an azide group. The binding of the azide group to the alkyne-presenting molecules results in emission of a signal from the organic label moiety.

    Objective: To compare the safety and effectiveness of flexible ureteroscopy (F-URS) with transperitoneal laparoscopic ureterolithotomy (TPLU) in cases of obstructive pyelonephritis secondary to large proximal ureteral stones. Methods: A series of 42 patients presenting with obstructive pyelonephritis due to proximal ureteral stones larger than 1.5 cm were included from April 2006 to February 2015 in this comparative study. After drainage of pyonephrosis and resolution of sepsis, 22 patients treated with TPLU (Group I), and 20 patients were treated with F-URS (Group II). Preoperative patient and stone characteristics, procedure-related parameters and clinical outcomes were assessed for each group. Results: It was seen that both methods were effective in the treatment of large proximal ureteral stones. However TPLU provided a higher stone- free rate (100% vs 80%. p=0.043) and lower retreatment rate. There was no difference between the groups for the operative time and complication rate. On the other hand, patients treated with F-URS had less postoperative pain (p=0.008), a shorter hospital stay (p<0.001) and a faster return to daily activities (p<0.001). Conclusions: The results of our study show that both F-URS and TPLU are safe and effective surgical procedures for treatment of large proximal ureteral stones after controlling obstructive pyelonephritis. However, TPLU has a higher stone-free rate with comparable operating time and complication rate as compared to F-URS. On the other hand F-URS has the advantages of less postoperative pain, shorter hospital stay and faster return to daily activities. PMID:27375691

    To find out the frequency of co-existence of malaria and dengue fever in patients presenting with acute febrile illness. Methods: The descriptive cross-sectional study was conducted at the Military Hospital Rawalpindi from June to November 2012. A total of 500 patients with complaint of acute febrile illness were selected after applying the inclusion and exclusion criteria. Preliminary data was collected on a pretested proforma. Blood samples of patients were tested for dengue serology and malaria parasite. Results were entered in respective proforma. Co-existence was considered present when a patient had both dengue serology and malaria parasite slide positive. SPSS 20 was used for data analysis. Result: Of the total, 349 (69.8%) were males and 151 (30.2%) females. Dengue serology was positive in 16 (3.2%); 81(16.2%) had malaria parasite slide positive; 403 (80.4%) had none of the two findings. Co-existence of both dengue and malaria was nil among the whole sample. In males, 67 (13.4%) had malaria, while 11 (2.2%) had dengue. In females, 14 (2.8%) had malaria, while 5 (1%) suffered from dengue fever. Conclusion: Co-existence of dengue and malaria was zero per cent in 500 patients visiting Military Hospital Rawalpindi. More studies shall be conducted to find out whether the reason of having zero per cent co-existence is that dengue or/and malaria epidemic did not occur in 2012 or whether there are some other factors involved.

    Full Text Available Bronchobiliary Fistula (BBF is a rare condition that usually occurs after surgical treatments of pancreas, liver and biliary diseases. Clinical findings are bilioptysis, fever and dyspnea. In treating it, initially, drainage should be conducted using minimally invasive or endoscopic methods, such as endoscopic retrograde cholangiopancreatography (ERCP or percutaneous transhepatic cholangiography (PTK in cases where these methods failed. Next, treatment through performing surgical operations, like hepatectomy or pulmonary resection, should be carried out. In this work, the diagnostic and therapeutic phases of a female patient at the age of 40 who underwent a whipple procedure (pancreatoduodenectomy 10 years earlier because of pancreatic neuroendocrine tumor is presented. Their follow-ups exhibited multiple metastases in the liver, and for this reason, specific chemoembolization treatments were applied. After these treatments, bronchobiliary fistula was formed.

    Full Text Available Background. In Haiti, breast cancer patients present at such advanced stages that even modern therapies offer modest survival benefit. Identifying the personal, sociocultural, and economic barriers-to-care delaying patient presentation is crucial to controlling disease. Methods. Patients presenting to the Hôpital Bon Sauveur in Cange were prospectively accrued. Delay was defined as 12 weeks or longer from initial sign/symptom discovery to presentation, as durations greater than this cutoff correlate with reduced survival. A matched case-control analysis with multivariate logistic regression was used to identify factors predicting delay. Results. Of N=123 patients accrued, 90 (73% reported symptom-presentation duration and formed the basis of this study: 52 patients presented within 12 weeks of symptoms, while 38 patients waited longer than 12 weeks. On logistic regression, lower education status (OR = 5.6, P=0.03, failure to initially recognize mass as important (OR = 13.0, P<0.01, and fear of treatment cost (OR = 8.3, P=0.03 were shown to independently predict delayed patient presentation. Conclusion. To reduce stage at presentation, future interventions must educate patients on the recognition of initial breast cancer signs and symptoms and address cost concerns by providing care free of charge and/or advertising that existing care is already free.

    Objective: To report the prevalence of abnormal exercise tolerance test (ETT) responses and to assess the risk factors for ischemic heart disease (IHD) in a population referred for the evaluation of chest pain with a normal baseline electrocardiogram (ECG). Design: A prospective study. The study was conducted at the National Institute of cardiovascular Diseases (NICVD), Karachi, Pakistan between 1st January 2000 and 31 December 2000. Subjects and Methods: One thousand one hundred and twenty-seven consecutive adult patients presenting in the outpatient department (OPD) with history of chest pain and having a normal baseline ECG were the subjects of the study after excluding patients with indeterminate or inconclusive test response. All these subjects underwent ETT and were screened for risk factor for IHD. Results: Of the patients studied 56.6% had abnormal ETT response. Male to female ratio of all patients was 4.85:1 Overall mean age was 50.3 +- 8.8 years. 65.9% of diabetic patients had ETT Suggestive of silent myocardial ischemia (p=0.012). Age > 50 year (p= <0.0001), male sex (p=0.015), diabetes mellitus (p=0.0033) and positive family history of IHD (p=0.0014) were the risk factor found in patient with abnormal ETT response. Conclusion: Age of more than 50 years, male gender, diabetes mellitus and positive family history of IHD are the significant risk factors for the development of ischemic heart disease in our population. Silent myocardial ischemic is common in diabetics. (author)

    Full Text Available AIMS : To study the prevalence of the meibomian gland disease in typ e 2 diabetic patients and its clinical presentations. SETTING AND DESIGN : A hospital based cross sectional descriptive study of 100 type 2 diabetic patients attending a medical college was conducted. METHODS : Detailed diabetic history was recorded. Assessment of ocular surface i.e. the lid margins , conjunctiva , corneal surface was done via slit lamp biomicroscopy. Meibomian gland disease (MGD severity was assessed by the quality and expressibility of the meibomian secretion. Dry eye tests like schir mer’s test and tear film breakup time were done. STATISTICAL ANALYSIS USED : SPSS statistical software version 17 was used. RESULTS : 56% of the patients out of 100 diabetic patients had MGD. The most common symptom was burning (46.9% , followed by dryness ( 23.5% , 5.6% had conjunctival injection , 7.14% had corneal erosions , 25% had mucus debris , 53.65% had dry eye which was statistically significant (p=0.001 , 56.25% males and 72.2% females had the disease which was not statistically significant. CONCLUSION : The prevalence of Meibomian gland disease in the diabetic population was 56% which is more than the general population prevalence. Apart from other disorders diabetics are also more prone for ocular surface diseases like Meibomian gland disease. MGD is an important pre disposer for severe diseases like Dry eye in this subgroup of patients which can lead to complications like conjunctival keratinisations , corneal erosions and perforations. Careful examination of these patients for ocular surface disease and prompt treatment is required.

    Full Text Available Introduction: Emergency overcrowding is defined as when the amount of care required for patients overcomes the available amount. This can cause delays in delivering critical care in situations like stroke. Objective: The aim of this study was to assess the possible impact of emergency department (ED crowding on the quality of care for acute stroke patients. Methods: In this cross-sectional prospective study, all patients with symptoms of acute stroke presenting to the ED of educational hospitals were enrolled. All patients were assessed and examined by the emergency medicine (EM residents on shift and a questionnaire was filled out for them. The amount of time that passed from the first triage to performing the required interventions and delivering health services were recorded by the triage nurse. ED crowding was measured by the occupancy rate. Then, the correlation between all of the variables and ED crowding level were calculated. Results: The average daily bed occupancy rate was 184.9 ± 54.3%. The median time passed from the first triage to performing the interventions were as follows: the first EM resident visit after 34 min, the first neurologic visit after 138 min, head CT after 134 min, ECG after 104 min and ASA administration after 210 min. There was no statistically significant relationship between the ED occupancy rate and the time elapsed before different required health services in the management of stroke patients either throughout an entire day or during each 8-hour interval (p > 0.05. Conclusion: In the current study, the ED occupancy rate was not significantly correlated with the time frame associated with management of admitted acute stroke patients.

    To provide adequate care, medical professionals have to collect not only medical information but also information that may be related to private aspects of the patient's life. With patients' increasing awareness of information privacy, healthcare providers have to pay attention to the patients' right of privacy. This study aimed to clarify the requirements of the display method of electronic patient record (EPR) screens in consideration of both patients' information privacy concerns and health professionals' information needs. For this purpose, semi-structured group interviews were conducted of 78 medical professionals. They pointed out that partial concealment of information to meet patients' requests for privacy could result in challenges in (1) safety in healthcare, (2) information sharing, (3) collaboration, (4) hospital management, and (5) communication. They believed that EPRs should (1) meet the requirements of the therapeutic process, (2) have restricted access, (3) provide convenient access to necessary information, and (4) facilitate interprofessional collaboration. This study provides direction for the development of display methods that balance the sharing of vital information and protection of patient privacy.

    Background: Computed tomographic colonography (CTC) is now an established method for imaging the colon and rectum in the screening and symptomatic setting. Additional benefit of CTC is the ability to assess for extracolonic findings especially in patients presenting with colorectal symptoms. Purpose: To determine prevalence of extracolonic findings (ECF) in symptomatic patients undergoing CTC and determine accuracy of CTC for exclusion of significant abdominal disease and extracolonic malignancy (ECM). Material and Methods: A total of 1359 unenhanced prone and postcontrast supine CTC studies were performed between March 2002 and December 2007. ECF were retrospectively classified according to C-RADS criteria into E1 to E4 findings. For ECM, a gold standard of clinical and/or radiological follow-up supplemented with data from the regional cancer registry with a median follow-up of 42 months was created. Sensitivity and negative predictive values for ECM was calculated. Results: Following exclusions, 1177 CTCs were analyzed. Of 1423 extracolonic findings reported, 328/1423 (23%) E3 and 100/1423 (7%) E4 (including six eventual FP studies) findings were identified. Thirty-two ECMs were confirmed following further investigations. Seven further small ECMs were detected during the entire follow-up, of which two were potentially visible in retrospect (false-negative studies). Additional tests were generated from 55/1177 (4.7%) studies. Sensitivity and negative predictive value for ECM was 94.1% (95% CI 78.9 - 98.9%) and 99.8% (95% CI 99.3 - 99.9%), respectively. Conclusion: One in 37 patients were found to have an ECM. Two potentially detectable cancers were missed. Only a small proportion of patients underwent additional work-up.

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

    The aim of this study was to determine whether a patient educator presentation (PEP) on pemphigus vulgaris would increase second-year dental students' awareness of the importance of learning about rare conditions and improve their retention of rare disease knowledge. The study involved students' subjective assessments of a PEP experience at two U.S. dental schools. In this mixed methods study, cross-sectional data were obtained by surveys and in-depth interviews. Questions focused on students' assessment of the messages acquired from the PEP and its likely impact on their future clinical care. At University 1, students completed paper surveys with open-ended questions and participated in a focus group. At University 2, students completed an online survey consisting of rating scale and open-ended questions. Responses to open-ended questions were categorized into themes. At University 1, 79 students (out of a possible 102; response rate 77.5%) completed the survey, and an additional ten students participated in a focus group. At University 2, 30 students (out of a possible 104; response rate 28.8%) completed the survey. At Universities 1 and 2, 88% and 100%, respectively, of respondents stated the PEP would influence their future clinical decision making. The vast majority of respondents (94% and 100% at University 1 and University 2, respectively) were of the opinion that the personal testimonial from a patient would help them recall information about pemphigus vulgaris in five years' time. Respondents from both universities commented that the PEP emphasized the importance of not dismissing a patient's concerns. These results suggest that a presentation by a patient with a rare condition can be an effective educational tool for preclinical dental students.

    Full Text Available BACKGROUND Rheumatoid Arthritis (RA is a chronic inflammatory disease of unknown aetiology marked by a symmetric peripheral polyarthritis. It is the most common form of chronic inflammatory arthritis and often results in joint damage and physical disability. The name is based on the term "rheumatic fever", an illness, which includes joint pain and is derived from the Greekword ῥεύμα-rheuma (nom., ῥεύματος-rheumatos (gen. ("flow, current". The suffix oid ("resembling" gives the translation as joint inflammation that resembles rheumatic fever. The first recognised description of rheumatoid arthritis was made in 1800 by Dr. Augustin Jacob Landré-Beauvais (1772-1840 of Paris. Because, it is a systemic disease, RA may result in a variety of extra-articular manifestations including fatigue, subcutaneous nodules, lung involvement, pericarditis, peripheral neuropathy, vasculitis and haematologic abnormalities. MATERIALS AND METHODS Patients who were diagnosed cases of rheumatoid arthritis attending the rheumatology clinic were referred to the Ophthalmology OPD in Government Medical College, Thrissur, for detailed eye examination. RESULTS The study was conducted in 100 patients (88 females and 12 males. Rheumatoid Factor (RF was found to be positive in 60 patients (60%, presence of dry eye did not correlate with rheumatoid positivity (Fishers exact test- the two-tailed P value = 0.4256. Through various tests, we concluded that there was aqueous deficiency in 61% and mucin deficiency in 46% of the patients. Other ocular manifestations present were- scleritis (2%, episcleritis (2% and keratomalacia (2%. CONCLUSION From the present study, we found out that extra-articular involvement of organs in rheumatoid arthritis is significant. The main ocular manifestations in rheumatoid arthritis found in our study were keratoconjunctivitis sicca, episcleritis, scleritis and keratomalacia. Though keratoconjunctivitis sicca was the most common, it did

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

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

    Eight patients presented with simultaneous multiple myeloma and acute renal failure requiring hemodialysis. Patients had no known pre-existing renal disease nor exposure to nephrotoxic agents or x-ray contrast dye. Renal failure was attributed to light chain nephropathy in all cases. In 4 of these patients the diagnosis of myeloma was initially unsuspected. Renal biopsies in 3 of these patients, and post-mortem material in a fourth revealed the changes of "myeloma kidney." No patient regained renal function and all required chronic hemodialysis. Among these eight patients, three survived for periods greater than 21 months.

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

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

    Music festivals, including electronic dance music events (EDMEs), increasingly are common in Canada and internationally. Part of a US $4.5 billion industry annually, the target audience is youth and young adults aged 15-25 years. Little is known about the impact of these events on local emergency departments (EDs). Drawing on prospective data over a 2-day EDME, the authors of this study employed mixed methods to describe the case mix and prospectively compared patient presentation rate (PPR) and ambulance transfer rate (ATR) between a first aid (FA) only and a higher level of care (HLC) model. There were 20,301 ticketed attendees. Seventy patient encounters were recorded over two days. The average age was 19.1 years. Roughly 69% were female (n=48/70). Forty-six percent of those seen in the main medical area were under the age of 19 years (n=32/70). The average length of stay in the main medical area was 70.8 minutes. The overall PPR was 4.09 per 1,000 attendees. The ATR with FA only would have been 1.98; ATR with HLC model was 0.52. The presence of an on-site HLC team had a significant positive effect on avoiding ambulance transfers. Twenty-nine ambulance transfers and ED visits were avoided by the presence of an on-site HLC medical team. Reduction of impact to the public health care system was substantial. Electronic dance music events have predictable risks and patient presentations, and appropriate on-site health care resources may reduce significantly the impact on the prehospital and emergency health resources in the host community.

    Background Somatically acquired genomic alterations with MYCN amplification (MNA) are key features of neuroblastoma (NB), the most common extra-cranial malignant tumour of childhood. Little is known about the frequency, clinical characteristics and outcome of NBs harbouring genomic amplification(s) distinct from MYCN. Methods Genomic profiles of 1100 NBs from French centres studied by array-CGH were re-examined specifically to identify regional amplifications. Patients were included if amplifications distinct from the MYCN locus were seen. A subset of NBs treated at Institut Curie and harbouring MNA as determined by array-CGH without other amplification was also studied. Clinical and histology data were retrospectively collected. Results In total, 56 patients were included and categorised into 3 groups. Group 1 (n = 8) presented regional amplification(s) without MNA. Locus 12q13-14 was a recurrent amplified region (4/8 cases). This group was heterogeneous in terms of INSS stages, primary localisations and histology, with atypical clinical features. Group 2 (n = 26) had MNA as well as other regional amplifications. These patients shared clinical features of those of a group of NBs MYCN amplified (Group 3, n = 22). Overall survival for group 1 was better than that of groups 2 and 3 (5 year OS: 87.5%±11% vs 34.9%±7%, log-rank p<0.05). Conclusion NBs harbouring regional amplification(s) without MNA are rare and seem to show atypical features in clinical presentation and genomic profile. Further high resolution genetic explorations are justified in this heterogeneous group, especially when considering these alterations as predictive markers for targeted therapy. PMID:25013904

    Computed tomographic colonography (CTC) is now an established method for imaging the colon and rectum in the screening and symptomatic setting. Additional benefit of CTC is the ability to assess for extracolonic findings especially in patients presenting with colorectal symptoms. To determine prevalence of extracolonic findings (ECF) in symptomatic patients undergoing CTC and determine accuracy of CTC for exclusion of significant abdominal disease and extracolonic malignancy (ECM). A total of 1359 unenhanced prone and postcontrast supine CTC studies were performed between March 2002 and December 2007. ECF were retrospectively classified according to C-RADS criteria into E1 to E4 findings. For ECM, a gold standard of clinical and/or radiological follow-up supplemented with data from the regional cancer registry with a median follow-up of 42 months was created. Sensitivity and negative predictive values for ECM was calculated. Following exclusions, 1177 CTCs were analyzed. Of 1423 extracolonic findings reported, 328/1423 (23%) E3 and 100/1423 (7%) E4 (including six eventual FP studies) findings were identified. Thirty-two ECMs were confirmed following further investigations. Seven further small ECMs were detected during the entire follow-up, of which two were potentially visible in retrospect (false-negative studies). Additional tests were generated from 55/1177 (4.7%) studies. Sensitivity and negative predictive value for ECM was 94.1% (95% CI 78.9-98.9%) and 99.8% (95% CI 99.3-99.9%), respectively. One in 37 patients were found to have an ECM. Two potentially detectable cancers were missed. Only a small proportion of patients underwent additional work-up.

    Atopic patients with chronic obstructive pulmonary disease (COPD) demonstrate more severe symptoms than their non-atopic counterparts. Also, Aspergillus hypersensitivity is known in COPD. However, allergic sensitisation to non-Aspergillus fungi has never been studied in COPD patients. To evaluate the prevalence of fungal sensitisation and its impact on the clinical presentation and outcome of COPD patients. Sensitisation to 17 fungi was studied in 55 COPD patients through skin prick tests, fungus-specific IgE, precipitating antibodies, total IgE and eosinophil counts. The clinical symptoms of patients were monitored thorough a patient-administered questionnaire. Overall, 5.4% (n = 3) of COPD patients were fungus sensitive. The sensitisation was noted to Alternaria alternata and Schizophyllum commune in two patients each, whereas another was sensitive to A. tamarii, Rhizopus spp. and Aspergillus fumigatus. Eosinophils were higher in fungus-sensitised patients (P = 0.001 vs. 0.003). No differences were noted in the clinical presentation of patients sensitised to fungi compared to those not sensitised to fungi or non-atopic. Although low, fungal sensitisation occurs in COPD but it is not limited to Aspergilli alone. Fungus-sensitised patients exhibit greater eosinophilia, implying more severe inflammation. Thus, such patients should be followed up regularly to recognise clinical worsening or development of ABPM. © 2015 Blackwell Verlag GmbH.

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

    Introduction Comprehensive studies on the relationship between patient demographics and subsequent treatment and disposition at a single mass-gathering event are lacking. The Sydney Royal Easter Show (SRES; Sydney Olympic Park, New South Wales, Australia) is an annual, 14-day, agricultural mass-gathering event occurring around the Easter weekend, attracting more than 800,000 patrons per year. In this study, patient records from the SRES were analyzed to examine relationships between weather, crowd size, day of week, and demographics on treatment and disposition. This information would help to predict factors affecting patient treatment and disposition to guide ongoing training of first responders and to evaluate the appropriateness of staffing skills mix at future events. Hypothesis Patient demographics, environmental factors, and attendance would influence the nature and severity of presentations at the SRES, which would influence staffing requirements. A retrospective analysis of 4,141 patient record forms was performed for patients who presented to St John Ambulance (Australian Capital Territory, Australia) at the SRES between 2012 and 2014 inclusive. Presentation type was classified using a previously published minimum data set. Data on weather and crowd size were obtained from the Australian Bureau of Meteorology (Melbourne, Victoria, Australia) and the SRES, respectively. Statistical analyses were performed using SPSS v22 (IBM; Armonk, New York USA). Between 2012 to 2014, over 2.5 million people attended the SRES with 4,141 patients treated onsite. As expected, the majority of presentations were injuries (49%) and illnesses (46%). Although patient demographics and presentation types did not change over time, the duration of treatment increased. A higher proportion of patients were discharged to hospital or home compared to the proportion of patients discharged back to the event. Patients from rural/regional locations (accounting for 15% of all patients) were

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

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

    Full Text Available Purpose: To report a case of isolated medial orbital wall fracture with enophthalmos in a paediatric patient and describe the clinical presentation and findings by means of computed tomography (CT of the head and eyes. Methods: We looked at the patient’s medical and ophthalmologic history, and an ophthalmologic examination and a CT of the head were performed at baseline. Results: A 14-year-old boy was admitted to the emergency department of our institution with ecchymosis of his right eyelids secondary to a sport accident. Physical examination revealed a moderate limitation of upgaze without diplopia. CT showed a medial orbital wall fracture without haemorrhage and a gross accumulation of air in the right eyelid with pressure exertion over the right globe and enophthalmos. The patient was treated conservatively with oral antibiotics and steroids showing dramatic improvement within 1 week. Enophthalmos and periorbital emphysema were completely resolved within 3 months after the accident as indicated by CT. Conclusions: We conclude that surgical intervention and intravenous treatment are not warranted in similar cases of medial orbital wall fracture. Medical history, clinical and paraclinical evaluations, and a regular follow-up, including CT, are needed though to avoid complications such as painful abduction, horizontal diplopia, pseudo sixth nerve paresis, or pseudo Duane.

    Objective: To study the MRI features of nasopharyngeal carcinoma (NPC) in patients who presented with ocular abnormalities. Methods: The clinical signs and MRI features of Ⅲ, Ⅳ and/or Ⅵ cranial nerve involvement in 22 cases of histologically proved nasopharyngeal carcinoma were retrospectively analyzed. Results: All 22 cases showed perineural tumor spread along the course of Ⅲ, Ⅳ and Ⅵ cranial nerve, Diplopia was the most common sign, occurred in 14/22 patients. The incidence of incomplete palsy of Ⅲ, Ⅳ and Ⅵ cranial nerve were 16/44, 7/44 and 4/44, respectively. There were four types of abnormal MRI findings: cavernous sinus thickening (10/44) and mass (16/44), superior orbital fissure enlargement (4/44) and abnormal signals (9/44), thickened oculomotor muscles with obscured adjacent fatty space and abnormal enhancement (10/44). The dynamic contrast enhancement patterns of the masses in cavernous sinus and orbital were the same as that of nasopharynx lesions; all appeared as rapid initial enhancement followed by a plateau phase. Conclusion: Oculomotor nerve involvement can be the first clinical signs of NPC, and MRI can show the perineural extension along the Ⅲ, Ⅳ and Ⅵ cranial nerve in NPC. (authors)

    Full Text Available Although brain has been the most common site for toxoplasma infection in acquired immunodeficiency syndrome patients, involvement of spinal cord by toxoplasma has been rarely found. Spinal cord toxoplasmosis can present as acute onset weakness in both lower limbs associated with sensory and bladder dysfunction. A presumptive diagnosis can be made in patients with CD4 count <100/mm 3 based on a positive serum Toxoplasma gondii IgG antibodies, no recent prophylaxis against toxoplasmosis, intramedullary ring enhancing lesion in spinal cord supported by similar lesions in brain parenchyma. Institutions of antitoxoplasma treatment in such patients result in prompt clinical response and therefore avoiding the need of unnecessary invasive diagnostic tests. Here, we report a case of toxoplasmic myelitis in immunocompromised patient presenting as myelopathy who showed significant clinical improvement after starting antitoxoplasma treatment. Hence toxoplasmic myelitis should be considered in toxoplasma seropositive immunocompromised patients presenting as myelopathy and imaging studies showing ring enhancing intramedullary lesion.

    Patient portals are considered valuable instruments for self-management of long term conditions, however, there are concerns over how patients might interpret and act on the clinical information they access. We hypothesized that visual cues improve patients' abilities to correctly interpret laboratory test results presented through patient portals. We also assessed, by applying eye-tracking methods, the relationship between risk interpretation and visual search behaviour. We conducted a controlled study with 20 kidney transplant patients. Participants viewed three different graphical presentations in each of low, medium, and high risk clinical scenarios composed of results for 28 laboratory tests. After viewing each clinical scenario, patients were asked how they would have acted in real life if the results were their own, as a proxy of their risk interpretation. They could choose between: 1) Calling their doctor immediately (high interpreted risk); 2) Trying to arrange an appointment within the next 4 weeks (medium interpreted risk); 3) Waiting for the next appointment in 3 months (low interpreted risk). For each presentation, we assessed accuracy of patients' risk interpretation, and employed eye tracking to assess and compare visual search behaviour. Misinterpretation of risk was common, with 65% of participants underestimating the need for action across all presentations at least once. Participants found it particularly difficult to interpret medium risk clinical scenarios. Participants who consistently understood when action was needed showed a higher visual search efficiency, suggesting a better strategy to cope with information overload that helped them to focus on the laboratory tests most relevant to their condition. This study confirms patients' difficulties in interpreting laboratories test results, with many patients underestimating the need for action, even when abnormal values were highlighted or grouped together. Our findings raise patient safety

    Aim: To present the magnetic resonance imaging (MRI) findings of 10 patients with histopathologically proven tuberculous spondylitis (TS) presenting as vertebra plana (VP) on radiographs. Material and methods: Radiographs of 451 adult TS patients were reviewed. In this consecutive series, there were 11 patients who presented as VP. MRI of 10 of these patients was available for review. Results: VP-like collapse of a single vertebral body of the dorsal spine with preserved endplates and disc was seen in all cases. Epidural, pre- and para-vertebral soft tissue was found in all patients. Epidural soft tissue presenting on sagittal images as a convexity of the posterior longitudinal ligament was also found in all the signal of which was different from the involved vertebra on axial images. All patients showed posterior element involvement, which was characterized by preserved cortical outline without expansion. Conclusion: TS presenting with VP-like collapse of the bone is rare, accounting for 2.4% of the cases in the present series. MRI may show a collapsed vertebra with preserved endplates and disc. MRI findings that are suggestive of TS include: (1) signal intensity of the epidural soft-tissue mass on axial images, which is different from the vertebral body; (2) presence of a thin, T2-weighted hypointense capsule of the para-vertebral soft tissue; (3) posterior element involvement characterized by intact hypointense cortical outline without expansion; and (4) involvement of the costovertebral joint.

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

    Three novel interaction methods were designed for reading six-dot Braille characters from the touchscreen of a mobile device. A prototype device with a piezoelectric actuator embedded under the touchscreen was used to create tactile feedback. The three interaction methods, scan, sweep, and rhythm, enabled users to read Braille characters one at a time either by exploring the characters dot by dot or by sensing a rhythmic pattern presented on the screen. The methods were tested with five blind Braille readers as a proof of concept. The results of the first experiment showed that all three methods can be used to convey information as the participants could accurately (91-97 percent) recognize individual characters. In the second experiment the presentation rate of the most efficient and preferred method, the rhythm, was varied. A mean recognition accuracy of 70 percent was found when the speed of presenting a single character was nearly doubled from the first experiment. The results showed that temporal tactile feedback and Braille coding can be used to transmit single-character information while further studies are still needed to evaluate the presentation of serial information, i.e., multiple Braille characters.

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

    Objective The purpose of this study was to compare demographics and chief complaints of the new patient population at our institution's fee-for-service clinics to the patient population of practicing chiropractors in the United States. We also compared the prevalence of obesity and hypertension to reference standards for the adult population. Methods Patient data were obtained from the electronic health records. All records identified as new patients during October 2013 were included. Variables of interest were clinic site, patient demographics, blood pressure, body mass index (BMI), chief complaint, and ICD-9 codes. Descriptive statistics were computed and compared to reference standards from previous reports. Results During October 2013, there were 224 new patients that entered the clinics. The average patient was a 31- to 50-year-old white male. Our clinic patients differed from those seen by US chiropractors in the distribution of all demographic variables. For adult patients, 31.4% were overweight, 29% were obese, and 8% stage 1 or 2 hypertension. Conclusion New patients in the fee-for-service teaching clinics appear to be dissimilar to those of US practicing chiropractors in several important demographics, characteristics, and types of complaints. The new patients had lower levels of overweight, obesity, and hypertension compared to US reference standards. PMID:25162982

    BACKGROUND & HYPOTHESIS: Data on the clinical characteristics and outcome of patients presenting with acute coronary syndrome (ACS) according to their marital status is not clear. A total of 5334 patients presenting with ACS in 65 hospitals in 6 Middle East countries in the 2nd Gulf Registry of Acute Coronary Events (Gulf RACE-2) were studied according to their marital status (5024 married, 100 single, and 210 widowed patients). When compared to married patients, widowed patients were older and more likely to be female. Widowed patients were more likely to have diabetes mellitus, hypertension, history of heart failure, and peripheral vascular disease and were less likely to be tobacco users when compared to the other groups. Widowed patients were also more likely to present with atypical symptoms and have advanced Killip class. Widowed patients were more likely to present with non-ST-elevation myocardial infarction (NSTEMI) when compared to the other 2 groups. Widowed patients were more likely to have heart failure (P = 0.001), cardiogenic shock (P = 0.001), and major bleeding (P = 0.002) when compared to the other groups. No statistically significant difference was observed in regard to duration of hospital stay, door to needle time in STEMI patients, or cardiac arrhythmias between the various groups. Widowed patients had higher in-hospital, 30-day, and 1-year mortality rates (P = 0.001). Marital status was an independent predictor for in-hospital mortality. Widowed marital status was associated with worse cardiovascular risk profile, and worse in-hospital and 1-year outcome. Future work should be focused on whether the provision of psychosocial support will result in improved outcomes among this high-risk group. © 2012 Wiley Periodicals, Inc.

    A retrospective chart review was performed to characterize the clinical presentation, the characteristic combination of serologic and cerebrospinal fluid (CSF) abnormalities, and the neuroimaging findings of neurosyphilis (NS) patients who had epileptic seizures alone as an initial presenting symptom. In a 6.75-year period, 169 inpatients with NS were identified at Zhongshan Hospital (from June 2005 to February 2012). We demonstrated that 13 (7.7%) of the 169 NS patients had epileptic seizures alone as an initial presenting feature. Epileptic seizures occurred in NS patients with syphilitic meningitis (2 cases), meningovascular NS (5 cases), and general paresis (6 cases). The types of epileptic seizures included simple partial, complex partial with secondary generalization (including status epilepticus), and generalized seizures (no focal onset reported). Nine of NS patients with only epileptic seizures as primary symptom were misdiagnosed, and the original misdiagnosis was 69.23% (9/13). Ten (10/13, 76.9%) patients had an abnormal magnetic resonance imaging, and 7 (7/13 53.8%) patients had abnormal electroencephalogram recordings. In addition, the sera rapid plasma reagin (RPR) and Treponema pallidum particle agglutination (TPPA) from all 13 patients were positive. The overall positive rates of the CSF-RPR and CSF-TPPA were 61.5% and 69.2%, respectively. Three patients demonstrated CSF pleocytosis, and 9 patients exhibited elevated CSF protein levels. Therefore, NS with only epileptic seizures at the initial presentation exhibits a lack of specificity. It is recommended that every patient with clinically evident symptoms of epileptic seizures should have a blood test performed for syphilis. When the serology results are positive, all of the patients should undergo a CSF examination to diagnose NS. Copyright © 2013 Elsevier Inc. All rights reserved.

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

    The conventional risk factors for coronary artery disease (CAD) include hypertension, diabetes mellitus, hyperlipidaemia and cigarette smoking(1). There is a large body of evidence, which implicates these factors in the causation of coronary artery disease. Objective: To study the attern of the above-mentioned as well as additional risk factors including age, gender, family history, obesity and hepatitis B and C seropositivity in the population of patients undergoing coronary angiography at our tertiary care hospital.Methodology:In this cross-sectional survey, 465 patients undergoing coronary angiography were studied using a questionnaire as well as clinical and laboratory data. The information obtained included age, sex, clinical presentation, past medical history, family history, the presence or absence of previous ischemic heart disease, diabetes, hypertension and a history of smoking. A history of duration of diabetes and hypertension, their treatment and the presence or absence of complications was also noted. A proportion of patients had their fasting blood lipid levels measured. Height, weight and waist circumference as well as HepBsAg and anti-HCV levels were also determined.Results: The 465 patients studied included 383 males and 82 females. The mean age of all patients was 49.68 +- 0.464 years and the difference between genders was not significant. A past history of ischaemic heart disease was present in 31% of patients. Diabetes mellitus was present in 23% of males and 45% of females. A history of hypertension was present in 30.8% males and 70.7% of the females. Of the patients who could be studied, the mean LDL was 110.29 +- 1.706 mg/dL, the mean HDL was 41.01 +- 0.319 mg/dL and the mean TG was 189.67 +- 4.21 mg/dL. The difference in lipid profile values between male and female patients was not significant (p-value >0.05). Waist circumference was increased in 69.7% males and 93.9% females and here the difference between genders was significant, Hep

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

    Gross and microscopic haematuria both are a common cause of referral to urology clinics. It has a wide spectrum of differential. In many occasions, it is a presentation of underlining serious urological problems. Evaluation of gross and significant microscopic haematuria is of paramount importance. This study was conducted to assess and compare the findings and diagnostic competency of transabdominal ultrasonography (US) versus cystourethroscopy in patients with haematuria of lower urinary tract origin. Prospective hospital-based study done at Ibn Sina Specialized and Omdurman Military Hospitals from June 2012 to March 2013. The study included 109 patients. Structured questionnaires were used to gather data from patients. All patients were evaluated by transabdominal US before cystourethroscopy examination. One hundred and nine patients were studied. Patients' mean (SD) age was 57.9 (18.8) years. Fifty-four patients (49.5 %) presented with macroscopic haematuria, while 55 patients presented with microscopic haematuria. The sensitivity and specificity of the US in detecting prostate enlargement, vesical stones, bladder wall tumour, cystitis and schistosomiasis were [(84, 80 %); (82.6, 97.7 %); (64.7, 92.1 %); (15.3, 96.8 %); and (15.3, 98.9 %)], respectively, as compared to cystoscopic finding as the gold standard. Ultrasonography is accepted only as a first-line imaging tool for evaluation of haematuria in poor settings, but cannot replace or became as good as cystoscopy, which remains the gold standard.

    To describe the characteristics of patients with rheumatoid arthritis (RA) attending for physiotherapy management in Ireland. Managers of physiotherapy departments in the 53 hospitals in Ireland were invited to participate in a multi-centre observational study over a 6-month period. Data on patients with RA the day of presentation for physiotherapy management were recorded. These data related to patient demographic details, disease management, aids and appliances, splint and orthoses usage and occupational issues. The Health Assessment Questionnaire was also recorded for each patient. A total of 273 patients from eight physiotherapy departments participated in the survey (n = 199; 73% female). Mean age of the participants was 59.3 (SD 12.5) years with mean disease duration of 13.8 (SD 10.6) years. The majority of the patients were inpatients (n = 170, 62%). Sixty-eight per cent of patients had attended for previous physiotherapy treatment and 98% were under current rheumatologist care. Biologic therapies were prescribed to 11% of patients. Use of splint and foot orthoses was high with 133 patients (49%) wearing splints and 75 (31%) wearing foot orthoses. The majority of patients had moderate (n = 119, 44%) or severe (n = 94, 35%) disability as per Health Assessment Questionnaire (HAQ) score. Mean HAQ score was 1.5, with HAQ scores showing increasing disability with increasing age, disease duration and erythrocyte sedimentation rate (ESR) levels. Patients with RA attending for physiotherapy management present with varied profiles. This study provides valuable information on the characteristics of patients with RA attending for physiotherapy management which will contribute to physiotherapy service planning and delivery and will optimize patient care.

    There is a need for an ideal indicator of surgery in patients presenting with acute abdomen. Several markers have been analysed, but the search still continues as none have proven effective. This study aimed to analyse and compare the predictive value of plasma procalcitonin (PCT) strip test in patients presenting with acute abdomen and identify a useful cut-off value to differentiate patients that would benefit with surgery from those that require conservative management. A prospective study was conducted in the department of general surgery from June 2012 to June 2013. Plasma PCT was estimated by the semi-quantitative strip test. The levels of plasma PCT and other routinely used markers of inflammation were analysed and compared. Of the total of 58 patients, 44 patients (76%) were men with a mean age of 45 years. Forty patients required emergency surgical intervention. A plasma PCT value of >0.5 ng/mL at admission was 80% sensitive and 100% specific for predicting need for antibiotics in patients with acute abdomen that were managed conservatively. The mean plasma PCT value in the patients undergoing surgery (5.0-10.0 ng/mL) was significantly more than in those managed conservatively (0.5-2.0 ng/mL). Using receiver operating characteristic (ROC) curves a cut-off for plasma PCT of >5.0 ng/mL was 75% sensitive and 100% specific for considering surgical intervention in patients presenting with acute abdomen. Plasma PCT (value >5 ng/mL) could be used as an adjunct to clinical examination to predict requirement of surgery in patients presenting with acute abdomen. © 2015 Royal Australasian College of Surgeons.

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

    Full Text Available Hepatitis C virus (HCV infects B-lymphocytes, provokes cellular dysfunction and causes lymphoproliferative diseases such as cryoglobulinemia and non-Hodgkin's B-cell lymphoma. In the present study, we investigated the serum levels of kappa and lambda free light chains (FLC of immunoglobulins and the kappa/lambda FLC ratio in Brazilian patients with chronic HCV infection and cryoglobulinemia. We also analyzed the immunochemical composition of the cryoglobulins in these patients. Twenty-eight cryoglobulinemic HCV patients composed the target group, while 37 HCV patients without cryoglobulinemia were included as controls. The median levels of kappa and lambda FLC were higher in patients with cryoglobulinemia compared to controls (p = 0.001 and p = 0.003, respectively, but the kappa/lambda FLC ratio was similar in patients with and without cryoglobulinemia (p > 0.05. The median FLC ratio was higher in HCV patients presenting with advanced fibrosis of the liver compared to HCV patients without fibrosis (p = 0.004. Kappa and lambda FLC levels were strongly correlated with the IgA, IgG and IgM levels in the patients with cryoglobulinemia. In patients without cryoglobulinemia, the kappa FLC level was only correlated with the IgG level, whereas the lambda FLC were weakly correlated with the IgA, IgG and IgM levels. An immunochemical pattern of mixed cryoglobulins (MC, predominantly IgM, IgG, IgA and kappa light chain, was verified in these immune complexes. We concluded that HCV-infected patients presenting cryoglobulinemia have vigorous polyclonal B-lymphocyte activation due to chronic HCV infection and persistent immune stimulation.

    Objective: To document the frequency and risk factors of Hepatits B and C in Afghan patients presenting to a tertiary care hospital in Peshawar. Study Design: Descriptive study. Place and Duration of Study: Rehman Medical Institute (RMI), Peshawar from 1st January, 2012 to 31st December, 2012. Patients and Methods: A total of 2166 Afghan national were included in the study who underwent surgery in RMI through consecutive, non-probability sampling. Hepatits B surface antigen (HBsAg) and anti-HCV antibody tests were performed by ELISA method. All patients who were positive for either of the two or both were investigated by a researcher-administered questionnaire to find the risk factors for seropositivity of hepatitis. Results: Out of a total of 2166 patients, 104 patients (4.8%) were found to be positive. Seventy-eight patients (75%) were HepBsAg positive while 24 patients (23%) were anti-HCV antibodies positive while 2 patients were positive for both viruses. Re-use of unsterilized syringes (23%) and history of previous surgery (19.2%) were the most common risk factors whereas no risk factor could be identified in 15 patients (14%). Seventy nine patients (76%) were newly diagnosed at time of test while 25 patients (24%) were known cases of either HBV or HCV. Only one patient had clinical/laboratory features of chronic liver disease while no patient had underwent Hep B vaccination or had hepatocellular carcinoma. Conclusion: A high seroprevalance of HBV and HCV was found in this study. Reuse of unsterilized syringes, history of previous surgery and tattoos piercing were found to be the most common risk factors. (author)

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

    Purpose: A retrospective review of a single cancer center experience was undertaken to identify clinical or treatment prognostic factors for these unusual tumors, to allow for a recommendation regarding management. Methods and Materials: The charts of 76 women and 2 men with breast sarcoma and without distant metastases at presentation registered from 1958 to 1990 were reviewed. Pathology was centrally reviewed in 54 cases. Histology, tumor size, grade, nodal status, age, menopausal status, history of benign breast disease, extent of surgery, resection margins, and radiation dose were each examined as potential prognostic factors by univariate analysis. To allow an analysis of radiation dose, total dose was normalized to a daily fraction size of 2 Gy. Results: The median age at diagnosis was 50.5 years (13-82 years). The pathologic diagnosis was found to be malignant cystosarcoma phyllodes in 32 patients, with the remainder being stromal sarcoma (14), angiosarcoma (8), fibrosarcoma (7), carcinosarcoma (5), liposarcoma (4), other (8). Eighteen patients had grade I or II tumors, 43 had grade III or IV, and 18 were not evaluable. The 5- and 10-year actuarial rates for all 78 patients were 57% and 48% for cause-specific survival (CSS), and 47% and 42% for the relapse-free rates (RFR), respectively. The local relapse-free rate (LRFR) was 75% at both 5 and 10 years. The 5-year CSS for grade I or II tumors was 84% versus 55% for grade III or IV tumors (p = 0.01). Conservative surgery versus mastectomy did not lead to statistically significant different outcomes for CSS, RFR, or LRFR. The comparison of positive versus negative margins showed a 5-year LRFR of 33% versus 80% (p = 0.009). Pairwise comparisons of the 5-year CSS of 91% for > 48 Gy versus either 50% for ≤ 48 Gy or 50% for no radiation showed p-values of 0.03 and 0.06, respectively. Conclusion: The authors propose that if negative surgical margins can be achieved, breast sarcoma should be managed by

    Literature was searched for methods of removing uranium from drinking water. U.S. manufacturers and users of water-treatment equipment and products were also contacted regarding methods of removing uranium from potable water. Based on the results of these surveys, it was recommended that untreated, partially treated, and finished water samples from municipal water-treatment facilities be analyzed to determine the extent of removal of uranium by presently used procedures, and that additional laboratory studies be performed to determine what changes are needed to maximize the effectiveness of treatments that are already in use in existing water-treatment plants

    Patients presenting with neurogenic bladder often require urological procedures (urodynamic testing and botulinum toxin injections) and a preventive antibiotic therapy. We aimed to assess the efficacy of this little known strategy in a cohort of patients. All patients presenting with neurogenic bladder who underwent urological procedure were included in the study. They received an antibiotic therapy in accordance with the urine cytobacteriological examination results. The antibiotic therapy was initiated two days before the procedure and prolonged up until two days after the procedure if the culture was positive. Patients were treated with a single dose of fosfomycin-trometamol in case of a negative culture. The main study outcome was the occurrence of urinary tract infection (UTI), defined by a positive urine culture and symptoms, up until 14 days after the procedure. A total of 80 urological procedures were performed. Mean patient age was 47±13.1 years (sex ratio 1.22); 59 (73.8%) presented with asymptomatic bacteriuria before the procedure. Nine (11.1%) UTIs were recorded on Day 14, of which one (1.2%) was febrile. Two patients required an additional curative antibiotic therapy. No patient was hospitalized. Overall, 77.8% of UTIs were cured without antibiotic therapy. Screening and treating asymptomatic bacteriuria before urological procedures seems unnecessary and vainly exposes this population at high risk of infectious diseases to antibiotic therapies. This data should be confirmed by a randomized clinical trial. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

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

    Central nervous system (CNS) infectious diseases have high prevalence in developing countries and their proper diagnosis and treatment are very important for public health planning. Cryptococcus neoformans is a fungus that may cause several CNS manifestations, especially in immunocompromised patients. Cryptococcal meningitis is the most common type of involvement. Mass-effect lesions are uncommon: they are described as cryptococcomas and their prevalence is even lower among immunocompetent patients. The aim here was to report an extremely rare case of cryptococcoma causing a mass effect and mimicking a brain tumor in an immunocompetent patient. The literature on CNS cryptococcal infections was reviewed with emphasis on cryptococcomas. Clinical, surgical and radiological data on a female patient with this rare presentation of cryptococcoma mimicking a brain tumor are described. A 54-year-old female patient presented to the emergency department with a rapid-onset progressive history of confusion and completely dependency for basic activities. Neuroimaging showed a left occipital lesion and neurosurgical treatment was proposed. From histopathological evaluation, a diagnosis of cryptococcoma was established. She received clinical support with antifungals, but despite optimal clinical treatment, her condition evolved to death. Cryptococcal infections have several forms of presentation and, in immunocompetent patients, their manifestation may be even more different. Cryptococcoma is an extremely rare presentation in which proper surgical and clinical treatment should be instituted as quickly as possible, but even so, there is a high mortality rate.

    The impact of ethnicity and the socioeconomic status (SES) among Caucasians is not well studied. Here, we examine the impact of income on melanoma presentation and prognosis within a Caucasian cohort, accounting for ethnicity, as some reports suggest increased melanoma incidence in Ashkenazi Jewish (AJ) BRCA mutation carriers. We studied prospectively enrolled primary melanoma patients at New York University. SES data were estimated using United States' Census Bureau data and patient zip codes. We evaluated associations between ethnicity, SES, and baseline characteristics using the χ² test and multivariate logistic regression. We compared survival distributions using Kaplan-Meier curves, log-rank tests, and Cox proportional hazard ratios. Of the 1,339 enrolled patients, AJ represented 32% (n = 423). Apart from AJ being older at presentation (p < 0.001), no significant differences were observed in baseline characteristics between ethnic groups. Patients with a median household income (MHI) lower than the median of the cohort were significantly more likely to present with advanced stages (p < 0.001) compared to patients with a higher MHI. Shorter overall (p = 0.016) and post-recurrence survival (p = 0.042) was also observed in patients from lower-income households. Data suggest that disparities in melanoma presentation in Caucasians stratify according to income independent of ethnic background. © 2016 S. Karger AG, Basel.

    Hip abductor tendon (HAT) tearing is commonly implicated in greater trochanteric pain syndrome (GTPS), though limited information exists on the disability associated with this condition and specific presentation of these patients. To describe the clinical, functional and biomechanical presentation of patients with symptomatic HAT tears. Secondary purposes were to investigate the association between these clinical and functional measures, and to compare the pain and disability reported by HAT tear patients to those with end-stage hip osteoarthritis (OA). Prospective case series. One hundred forty-nine consecutive patients with symptomatic HAT tears were evaluated using the Harris (HHS) and Oxford (OHS) Hip Scores, SF-12, an additional series of 10 questions more pertinent to those with lateral hip pain, active hip range of motion (ROM), maximal isometric hip abduction strength, six-minute walk capacity and 30-second single limb stance (SLS) test. The presence of a Trendelenburg sign and pelvis-on-femur (POF) angle were determined via 2D video analysis. An age matched comparative sample of patients with end-stage hip OA was recruited for comparison of all patient-reported outcome scores. Independent t-tests investigated group and limb differences, while analysis of variance evaluated pain changes during the functional tests. Pearson's correlation coefficients investigated the correlation between clinical measures in the HAT tear group. No differences existed in patient demographics and patient-reported outcome scores between HAT tear and hip OA cohorts, apart from significantly worse SF-12 mental subscale scores (p = 0.032) in the HAT tear group. Patients with HAT tears demonstrated significantly lower (p presentation of these patients. Level 3 case-controlled study, with matched comparison.

    To examine age- and age-related differences in recall of information provided during oncology consultations. Two hundred sixty patients with cancer diagnosed with heterogeneous cancers, seeing a medical or radiation oncologist for the first time, participated in the study. Patients completed questionnaires assessing information needs and anxiety. Recall of information provided was measured using a structured telephone interview in which patients were prompted to remember details physicians gave about diagnosis, prognosis, and treatment. Recall was checked against the actual communication in audio-recordings of the consultations. Recall decreased significantly with age, but only when total amount of information presented was taken into account. This indicates that if more information is discussed, older patients have more trouble remembering the information than younger ones. In addition, recall was selectively influenced by prognosis. First, patients with a poorer prognosis recalled less. Next, the more information was provided about prognosis, the less information patients recalled, regardless of their actual prognosis. Recall is not simply a function of patient age. Age only predicts recall when controlling for amount of information presented. Both prognosis and information about prognosis are better predictors of recall than age. These results provide important insights into intervention strategies to improve information recall in patients with cancer.

    2002-08-01

    This article seeks to establish whether the poster presentation of a specific theme can facilitate the student's thinking skills in nursing education. A qualitative, exploratory, descriptive and contextual research design where twenty students volunteered to take part in the study by signing an informed consent was followed. Descriptive naïve sketches were used for data collection followed by individual interviews to validate the findings. Data was analysed by means of the descriptive method of open coding of Tesch (in Creswell, 1994:155). DENOSA's ethical standards for research (1998:7) were considered. The findings indicated both positive and negative perceptions. The positive perceptions were: a poster presentation as an evaluation method facilitates creative, critical and reflective thinking skills; group work facilitates student participation; it facilitates problem solving skills; it increases the student's independence and a sense of ownership; and the evaluation is fair. The negative perceptions were that there was a lack of clarity on the student's expectations and that group activity is difficult. Trustworthiness was maintained in accordance with Lincoln and Guba's principles (1985:290-327). It is concluded that a poster presentation, used effectively as an evaluation method, can facilitate the learner's critical and reflective thinking skills. It is recommended that other learner-centred methods of assessment and evaluation be researched for their effective use in facilitating the higher order thinking skills of learners.

    Full Text Available Studies have shown that own-race faces are more accurately recognised than other-race faces. The present study examined the effects of own- and other-race face recognition when different ethnicity targets are presented to the participants together. Also the effect of semantic information on the recognition of different race faces was examined. The participants (N = 234 were presented with photos of own-race and other-race faces. For some participants the faces were presented with stereotypical names and for some not. As hypothesized, own-race faces were better recognised in target-present lineup and more correctly rejected in target-absent lineup than other-race faces. Concerning presentation method, both own-race and other-race faces were more correctly identified in target-present simultaneous than in target-present sequential lineups. No effects of stereotypical names on face recognition were found. The findings suggest that identifying multi-ethnicity perpetrators is a problematic and difficult task.

  1. Discriminating active from latent tuberculosis in patients presenting to community clinics.

    Directory of Open Access Journals (Sweden)

    Gurjinder Sandhu

    Full Text Available Because of the high global prevalence of latent TB infection (LTBI, a key challenge in endemic settings is distinguishing patients with active TB from patients with overlapping clinical symptoms without active TB but with co-existing LTBI. Current methods are insufficiently accurate. Plasma proteomic fingerprinting can resolve this difficulty by providing a molecular snapshot defining disease state that can be used to develop point-of-care diagnostics.Plasma and clinical data were obtained prospectively from patients attending community TB clinics in Peru and from household contacts. Plasma was subjected to high-throughput proteomic profiling by mass spectrometry. Statistical pattern recognition methods were used to define mass spectral patterns that distinguished patients with active TB from symptomatic controls with or without LTBI.156 patients with active TB and 110 symptomatic controls (patients with respiratory symptoms without active TB were investigated. Active TB patients were distinguishable from undifferentiated symptomatic controls with accuracy of 87% (sensitivity 84%, specificity 90%, from symptomatic controls with LTBI (accuracy of 87%, sensitivity 89%, specificity 82% and from symptomatic controls without LTBI (accuracy 90%, sensitivity 90%, specificity 92%.We show that active TB can be distinguished accurately from LTBI in symptomatic clinic attenders using a plasma proteomic fingerprint. Translation of biomarkers derived from this study into a robust and affordable point-of-care format will have significant implications for recognition and control of active TB in high prevalence settings.

  2. Presentation of a method for the sequential analysis of incidents - NPP safety

    1989-04-01

    This paper presents a method which is designed to assist in the analysis of safety and based on the graphic representation of the occurrence of incidents significant for safety in 900-MWe PWR units. The graphs obtained are linked together to produce a general tree of events. With this tool, and on the basis of operating experience, it is then possible to imagine complex incident scenarios, to evaluate the potential consequences of a particular incident, or to seed out the causes which could lead to a given event. Interactions between systems or common mode faults can also be evidenced with this method.

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

    A 32 years old male patient is described with infection by the human immunodeficiency virus (HIV) on stage IV C1 and with positive Ag p24 who developed tuberculous meningitis of atypical presentation. A persistent liquoral neutrophilia and low adenosindeaminase values were observed in cerebrospinal fluid of purulent appearance. The patient responded badly to tuberculostatic treatment and died. In the antibiogram carried out resistance to Mycobacterium tuberculosis was observed to rifampicine and isoniazide, two of the five drugs the patient had received. The peculiarities of the clinical form of presentation similar to purulent bacterian meningitis are discussed, and the possible influence of HIV infection and the antibiotic multiresistance observed in the bad evolution of the tuberculous meningitis which the patient developed.

    Chronic respiratory system diseases become serious public health problem all over the world. The most prevalent are obstructive diseases (asthma and COPD). The prevalence of asthma is still high and concern patients representing wide range of age and socio-economic status. Despite progress in diagnostic and therapeutic options several studies showed that asthma has an impact on health-related quality of life and patients' coping. Asthma as chronic condition results in limitations of patients activity and social relations. Thus psychosocial variables, which may have an impact on asthma symptoms presentation and disease progress, should be considered. There are only few reports concerning cognitive functions in asthma. The aim of the study was to assess the potential impact of psychosocial factors on asthma symptoms presentation, and cognitive function in asthma patients.

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

    Available data correlating symptoms of colon cancer patients with the severity of the disease are very limited. In a population-based setting, we correlated information on symptoms of colon cancer patients with several pathological tumor parameters and survival. Information on all patients diagnosed with colon cancer in Iceland in 1995-2004 for this retrospective, population-based study was obtained from the Icelandic Cancer Registry. Information on symptoms of patients and blood hemoglobin was collected from patients' files. Pathological parameters were obtained from a previously performed standardized tumor review. A total of 768 patients entered this study; the median age was 73 years. Tumors in patients presenting at diagnosis with visible blood in stools were significantly more likely to be of lower grade, having pushing border, conspicuous peritumoral lymphocytic infiltration, and lower frequency of vessel invasion. Patients with abdominal pain and anemia were significantly more likely to have vessel invasion. Logistic regression showed that visible blood in stools was significantly associated with protecting pathological factors (OR range 0.38-0.83, p characteristics and adverse outcome for patients. © 2013 APMIS Published by Blackwell Publishing Ltd.

    Conclusion: This study identified 11.4% diabetics among TB patients presenting to a tertiary care facility. Despite the high diabetes incidence in Pakistan, 71% of the diabetics in the group studied did not know their status. Given the negative impact of diabetes on treatment outcomes of TB, it is important that screening for diabetes be included as initial workup for TB patients. Identification and management of diabetes would result in improved outcomes for TB treatment.

    The authors report a case of bowel infarction consequent to sudden occlusion of the superior mesenteric artery, with classical clinical and radiological presentation. The outcome, death of the patient, exemplified the usual difficulty in the early diagnosis. It is important, therefore, the urgent use of arteriography in patients with suspection of mesenteric ischemia, because the time of vascular injury predisposes to necrosis, the main prognostic factor.

    Objective The aim of the present study was to determine the rates of re-referral to specialist out-patient clinics for patients previously managed and discharged from an advanced practice physiotherapy-led service in three metropolitan hospitals. Methods A retrospective audit was undertaken of 462 patient cases with non-urgent musculoskeletal conditions discharged between 1 April 2014 and 30 March 2015 from three metropolitan hospitals. These patients had been discharged from the physiotherapy-led service without requiring specialist medical review. Rates and patterns of re-referral to specialist orthopaedic, neurosurgical, chronic pain, or rheumatology services within 12 months of discharge were investigated. Results Forty-six of the 462 patients (10.0%) who were managed by the physiotherapy-led service were re-referred to specialist medical orthopaedic, neurosurgical, chronic pain or rheumatology departments within 12 months of discharge. Only 22 of these patients (4.8%) were re-referred for the same condition as managed previously and discharged. Conclusions Ninety-five per cent of patients with non-urgent musculoskeletal conditions managed by an advanced practice physiotherapy-led service at three metropolitan hospitals did not re-present to access public specialist medical services for the same condition within 12 months of discharge. This is the first time that re-presentation rates have been reported for patients managed in advanced practice physiotherapy services and the findings support the effectiveness of these models of care in managing demand for speciality out-patient services. What is known about the topic? Advanced practice physiotherapy-led services have been implemented to address the needs of patients referred with non-urgent musculoskeletal conditions to hospital specialist out-patient services. Although this model is widely used in Australia, there has been very little information about whether patients managed in these services subsequently re-present

    We sought to characterize presenting electrocardiographic findings in patients with acute coronary syndromes (ACSs) and out-of-hospital cardiac arrest (OHCA). In the Global Registry of Acute Coronary Events and Canadian ACS Registry I, we examined presenting and 24- to 48-hour follow-up ECGs (electrocardiogram) of ACS patients who survived to hospital admission, stratified by presentation with OHCA. We assessed the prevalence of ST-segment deviation and bundle branch blocks (assessed by an independent ECG core laboratory) and their association with in-hospital and 6-month mortality among those with OHCA. Of the 12,040 ACS patients, 215 (1.8%) survived to hospital admission after OHCA. Those with OHCA had higher presenting rates of ST-segment elevation, ST-segment depression, T-wave inversion, precordial Q-waves, left bundle branch block (LBBB), and right bundle branch block (RBBB) than those without. Among patients with OHCA, those with ST-segment elevation had significantly lower in-hospital mortality (20.9% vs 33.0%, p = 0.044) and a trend toward lower 6-month mortality (27% vs 39%, p = 0.060) compared with those without ST-segment elevation. Conversely, among OCHA patients, LBBB was associated with significantly higher in-hospital and 6-month mortality rates (58% vs 22%, p presenting ECG resolved by 24 to 48 hours. In conclusion, compared with ACS patients without cardiac arrest, those with OHCA had higher rates of ST-segment elevation, LBBB, and RBBB on admission. Among OHCA patients, ST-segment elevation was associated with lower in-hospital mortality, whereas LBBB was associated with higher in-hospital and 6-month mortality. Copyright © 2017 Elsevier Inc.

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

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

    Celiac disease shares features of other disorders. It can be diagnosed conclusively only based on duodenal histology analysis, which is not practical for screening purposes. Serologic analysis might be used to identify candidates for biopsy analysis. We aimed to develop a simple diagnostic approach that all clinicians could follow to increase the percentage of patients accurately diagnosed with celiac disease at initial presentation. We performed a retrospective analysis of data from 752 patients (88 with celiac disease, none were IgA deficient) who attended a UK district general hospital from January 2007 through December 2008 and underwent biopsy analysis and serologic tests to measure endomyseal antibodies and IgA antibodies against tissue transglutaminase (tTG). Patients avoiding gluten in their diet were excluded. Patients were assigned to 1 of 4 groups: high-risk (based on presence of anemia, chronic diarrhea, unintentional weight loss, or dermatitis herpetiformis), low-risk (based on such factors as dyspepsia, abnormal liver function, ataxia, or chronic cough), nutrient deficiency (based on levels of iron, vitamins B12 and D, or folate), or screening (because they had type 1 diabetes or a family history of celiac disease). Patients with celiac disease were identified using the modified Marsh criteria (grades 1-3) for interpreting duodenal histology. We compared clinical category, serology profiles, and biopsy results between patients with and without celiac disease. Celiac disease was diagnosed in 64 of 565 patients in the high-risk group (11%), 14 of 156 patients in the low-risk group (9%; P = .47 compared with high-risk group), 7 of 28 patients in the nutrient-deficiency group, and 3 of 3 patients in the screening group. Among 71 patients who tested positive for both antibodies (tTG and endomyseal antibodies), the positive predictive value for celiac disease was 97%; a negative test result for tTG had a negative predictive value of 98%. Among 708 patients

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

    Eating disorders (EDs) have been underdiagnosed in many clinical settings. This study investigates the influence of clinical characteristics on presenting symptoms of patients with EDs. Psychiatric outpatients, aged 18-45, were enrolled sequentially and received a two-phase survey for EDs in August 2010-January 2013. Their primary reasons for seeking psychiatric help were obtained at their first encounter with outpatient psychiatrists. Patients' clinical and demographic characteristics were compared according to presenting symptoms with or without eating/weight problems. Of 2140 patients, 348 (16.3%) were diagnosed with an ED (22.6% of women and 6.3% of men). The three most common reasons for seeking psychiatric help were eating/weight problems (46.0%), emotional problems (41.3%), and sleep disturbances (19.3%). The multivariate analyses suggest that when patients with EDs presented symptoms that were less related to eating/weight problems, they were significantly more likely to be those having diagnoses other than anorexia nervosa or bulimia nervosa and less severe degree of binge-eating. Further, patients with EDs who demonstrated more impulsive behaviors and poorer functioning were less likely to report their eating problems when visiting psychiatric clinics. Thus, ED should be assessed routinely in patients with complex psychopathology to facilitate comprehensive treatment. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    As scenarios for exercises become more complicated and flexible to challenge emergency response personnel, improved means of presenting data must be developed. To provide maximum realism and free play during an exercise, staff at the Pacific Northwest Laboratory (PNL) have recently devised a simple method of presenting realistic radiological field monitoring information for a range of possible releases. The method uses only two pieces of paper. The first is a map of the offsite area showing the shape of the plume for the duration of the exercise. The second is a semilog graph containing curves that relate exposure rate and iodine concentration to downwind distance and time. Several techniques are used to maximize the information on the graph

    Dermoid cysts, encephaloceles, and dermal sinus tracts represent abnormalities that develop during the process of embryogenesis. The elucidation of the precise timing of formation for these malformations has remained elusive at the molecular level of study. Yet, clinical experience has demonstrated that these malformations do not all occur in the same patient, suggesting a shared pathway that goes awry at distinct points for different patients, resulting in 1 of the 3 malformations. Herein the authors describe a case in which all 3 malformations were present in a single patient. This is the first description in the English literature of a sincipital encephalocele occurring with a dermoid cyst and a dermal sinus tract.

    Death of patients presenting with bleeding events to the Emergency Department still represent a major problem. We sought to analyze clinical characteristics associated with worse outcomes including short- and long-term death, beyond antithombotic treatment strategy. Patients presenting with any bleeding events during 2016-2017years were enrolled. Clinical parameters, site of bleeding, major bleeding, ongoing anti-thrombotic treatment strategy and death were collected. Hard 5:1 propensity score matching was performed to adjust dead patients in baseline characteristics. Endpoints were one-month and one-year death. Out of 166,000 visits to the Emergency Department, 3.050 patients (1.8%) were enrolled and eventually 429 were analyzed after propensity. Overall, anticoagulants or antiplatelets were given to 234(54%). Major bleeding account for 111(26%) patients, without differences between those taking anticoagulants or antiplatelets versus others. Death at one-month and one-year was 26(6%) and 72(17%), respectively. Independent predictors of one-month death were major bleeding (Odds Ratio, OR 26, pbleeding (OR 7, pbleeding where higher than others (pbleeding and age (0.75 and 0.72, respectively) over others; pbleeding events, death rate was driven by major bleeding on short-term and older age on long-term.

    Full Text Available Background: Early diagnosis and treatment of human Immunodeficiency virus (HIV is not only beneficial for the people living with HIV/acquired immunodeficiency syndrome (AIDS (PLHA but for the public and society as well. The study was aimed to identify the factors associated with late presentation to HIV/AIDS care. Materials and Methods: A facility-based unmatched case-control (1:1 study along with in-depth qualitative assessment was conducted at an ART Plus center at a district hospital, Udupi, southern India. A sample of 320 HIV patients (160 cases and 160 controls was selected randomly between February and July 2014. Information regarding the patients were collected using an interviewer-administered semi-structured questionnaire. The qualitative component was assessed by in-depth interviews of 4 health professionals and 12 HIV-positive patients who were late for HIV care. The quantitative data were analyzed using Statistical Package for the Social Sciences (SPSS version 15.0. The technique of thematic analysis was adopted for the analysis of qualitative data. Results: HIV-positive individuals who lived with families [odds ratio (OR = 5.11], the patients having non-AIDS comorbidities [OR= 2.19, 95% confidence interval (CI: 1.09-4.40], the patients who perceived fear of losing family [OR = 5.00, 95% CI: 2.17-11.49], the patients who perceived fear that their status will be ruined in the community [OR= 2.00, 95% CI: 1.01-3.97], the patients who perceived fear of side effects of ART medications [OR = 4.3, 95% CI: 2.65-11.33], the patients who perceived fear of losing confidentiality [OR = 4.94, 95% CI: 2.54-9.59], the patients those who lack information available on government services [OR = 4.12, 95% CI: 2.127-8.005], and the patients who consumed alcohol [OR= 3.52, 95% CI: 1.83-6.77] were found to be independently associated with the late presentation to HIV/AIDS care after adjusting for all known confounders in a multivariable analysis.

    Purpose: Although palliative chemotherapy is the standard of care for patients with diagnoses of stage IV non-small cell lung cancer (NSCLC), patients with a small metastatic burden, “oligometastatic” disease, may benefit from more aggressive local therapy. Methods and Materials: We identified 186 patients (26% of stage IV patients) prospectively enrolled in our institutional database from 2002 to 2012 with oligometastatic disease, which we defined as 5 or fewer distant metastatic lesions at diagnosis. Univariate and multivariable Cox proportional hazards models were used to identify patient and disease factors associated with improved survival. Using propensity score methods, we investigated the effect of definitive local therapy to the primary tumor on overall survival. Results: Median age at diagnosis was 61 years of age; 51% of patients were female; 12% had squamous histology; and 33% had N0-1 disease. On multivariable analysis, Eastern Cooperate Oncology Group performance status ≥2 (hazard ratio [HR], 2.43), nodal status, N2-3 (HR, 2.16), squamous pathology, and metastases to multiple organs (HR, 2.11) were associated with a greater hazard of death (all P<.01). The number of metastatic lesions and radiologic size of the primary tumor were not significantly associated with overall survival. Definitive local therapy to the primary tumor was associated with prolonged survival (HR, 0.65, P=.043). Conclusions: Definitive local therapy to the primary tumor appears to be associated with improved survival in patients with oligometastatic NSCLC. Select patient and tumor characteristics, including good performance status, nonsquamous histology, and limited nodal disease, may predict for improved survival in these patients.

    Purpose: Although palliative chemotherapy is the standard of care for patients with diagnoses of stage IV non-small cell lung cancer (NSCLC), patients with a small metastatic burden, “oligometastatic” disease, may benefit from more aggressive local therapy. Methods and Materials: We identified 186 patients (26% of stage IV patients) prospectively enrolled in our institutional database from 2002 to 2012 with oligometastatic disease, which we defined as 5 or fewer distant metastatic lesions at diagnosis. Univariate and multivariable Cox proportional hazards models were used to identify patient and disease factors associated with improved survival. Using propensity score methods, we investigated the effect of definitive local therapy to the primary tumor on overall survival. Results: Median age at diagnosis was 61 years of age; 51% of patients were female; 12% had squamous histology; and 33% had N0-1 disease. On multivariable analysis, Eastern Cooperate Oncology Group performance status ≥2 (hazard ratio [HR], 2.43), nodal status, N2-3 (HR, 2.16), squamous pathology, and metastases to multiple organs (HR, 2.11) were associated with a greater hazard of death (all P<.01). The number of metastatic lesions and radiologic size of the primary tumor were not significantly associated with overall survival. Definitive local therapy to the primary tumor was associated with prolonged survival (HR, 0.65, P=.043). Conclusions: Definitive local therapy to the primary tumor appears to be associated with improved survival in patients with oligometastatic NSCLC.

    The main advantages of this particular method for analyzing the reliability and safety of systems, the method of failure combinations, are presented. This is an inductive method of analysis; it makes it possible to pursue the Failure Modes and Effect Analysis (FMEA) until overall failures are obtained. In this manner, through an inductive approach all the combinations of failure modes leading to abnormal functioning of systems are obtained. It also makes it possible to carry out the overall study of complex systems in interaction and the systematic inventory of abnormal functioning of these systems, as from the failure modes of the components and their combinations. It can be used as from the design stages of systems and is an excellent dialogue tool between the various specialists concerned in problems of safety, operation and reliability [fr

    Estimation of serum and urinary albumin is routinely performed in clinical biochemistry laboratories. In the past, precipitation-based methods were popular for estimation of human serum albumin (HSA). Currently, dye-binding or immunochemical methods are widely practiced. Each of these methods has its limitations. Research endeavors to overcome such limitations are on-going. The current trends in methodological aspects of albumin estimation guiding the field have not been reviewed. Therefore, it is the need of the hour to review several aspects of albumin estimation. The present review focuses on the modern trends of research from a conceptual point of view and gives an overview of recent developments to offer the readers a comprehensive understanding of the subject.

    A simplified method for elastic plastic analysis is presented. Material behavior is assumed to be elastic plastic with bilinear kinematic hardening. The proposed method give a strain-stress field fullfilling material constitutive equations, equations of equilibrium and continuity conditions. This strain-stress is obtained through two linear computations. The first one is the conventional elastic analysis of the body submitted to the applied load. The second one use tangent matrix (tangent Young's modulus and Poisson's ratio) for the determination of an additional stress due to imposed initial strain. Such a method suits finite elements computer codes, the most useful result being plastic strains resulting from the applied loading (load control or deformation control). Obviously, there is not unique solution, for stress-strain field is not depending only of the applied load, but of the load history. Therefore, less pessimistic solutions can be got by one or two additional linear computations [fr

    Full Text Available Background Despite reporting low levels of well-being, anorexia nervosa patients express temperament traits (e.g., extraversion and persistence necessary for high levels of life satisfaction. Nevertheless, among individuals without eating disorders, a balanced organization of the flow of time, influences life satisfaction beyond temperamental dispositions. A balanced time perspective is defined as: high past positive, low past negative, high present hedonistic, low present fatalistic, and high future. We investigated differences in time perspective dimensions, personality traits, and life satisfaction between anorexia nervosa patients and matched controls. We also investigated if the personality traits and the outlook on time associated to positive levels of life satisfaction among controls also predicted anorexia patients’ life satisfaction. Additionally, we investigated if time perspective dimensions predicted life satisfaction beyond personality traits among both patients and controls. Method A total of 88 anorexia nervosa patients from a clinic in the West of Sweden and 111 gender-age matched controls from a university in the West of Sweden participated in the Study. All participants responded to the Zimbardo Time Perspective Inventory, the Ten Item Personality Inventory, and the Temporal Satisfaction with Life Scale. Results A t-test showed that patients scored higher in the past negative, the present fatalistic, and the future dimensions, lower in the past positive and the present hedonistic dimensions, higher in conscientiousness, extraversion, and agreeableness, and lower in life satisfaction. Regression analyses showed that life satisfaction was predicted by openness to experience and emotional stability for controls and by emotional stability among patients. When time dimensions were entered in the regression, emotional stability and the past negative and past positive time dimensions predicted life satisfaction among controls, but

    Following the WHO initiative named World Alliance for Patient Safety (PS) launched in 2004 a conceptual framework developed by PS national reporting experts has summarized the knowledge available. As a second step, the Department of Public Health of the University of Saint Etienne team elaborated a Categorial Structure (a semi formal structure not related to an upper level ontology) identifying the elements of the semantic structure underpinning the broad concepts contained in the framework for patient safety. This knowledge engineering method has been developed to enable modeling patient safety information as a prerequisite for subsequent full ontology development. The present article describes the semantic dissection of the concepts, the elicitation of the ontology requirements and the domain constraints of the conceptual framework. This ontology includes 134 concepts and 25 distinct relations and will serve as basis for an Information Model for Patient Safety.

    Acute or subacute cerebellar inflammation is mainly caused by postinfectious, toxic, neoplastic, vascular, or idiopathic processes and can result in cerebellar ataxia. Previous magnetic resonance (MR) studies in single patients who developed acute or subacute ataxia showed varying imaging features. Eighteen patients presenting with acute and subacute onset of ataxia were included in this study. Cases of chronic-progressive/hereditary and noncerebellar causes (ischemia, multiple sclerosis lesions, metastasis, bleedings) were excluded. MR imaging findings were then matched with the clinical history of the patient. An underlying etiology for ataxic symptoms were found in 14/18 patients (postinfectious/infectious, paraneoplastic, autoimmune, drug-induced). In two of five patients without MR imaging findings and three of eight patients with minimal imaging features (cerebellar atrophy, slight signal alterations, and small areas of restricted diffusion), adverse clinical outcomes were documented. Of the five patients with prominent MR findings (cerebellar swelling, contrast enhancement, or broad signal abnormalities), two were lost to follow-up and two showed long-term sequelae. No correlation was found between the presence of initial MRI findings in subacute or acute ataxia patients and their long-term clinical outcome. MR imaging was more flagrantly positive in cases due to encephalitis. (orig.)

    To study the clinical presentation, treatment, and outcome of patients with retinoblastoma (RB) in India. Retrospective study of 1,457 patients with RB (2,074 eyes). The mean age at presentation of RB was 29 months (median, 24 months; range, presentation of RB in 57% (n = 834) and bilateral in 43% (n = 623). Familial RB was present in 4% (n = 55). The most common presenting complaints included leukocoria (n = 1,100; 75%), proptosis (n = 91; 6%), strabismus (n = 77; 5%), and red eye (n = 68; 5%). Most (n = 1,889; 91%) tumors were intraocular in location, and 185 (n = 185; 9%) had extraocular tumor extension at presentation. The most common modalities of primary treatment-included systemic chemotherapy (n = 1,171; 60%) and enucleation (n = 674; 35%). At a mean follow-up period of 44 months (median, 30 months; range, 3-234 months), 92% (n = 1,206) were alive, and 108 (8%) patients died because of RB. Based on Kaplan-Meier analysis, the survival at 1, 3, 5, and 10 years was 94%, 91%, 90%, and 89%, respectively. The most common presenting signs of RB in Asian Indian population are leukocoria and proptosis. With appropriate treatment, the survival rate is favorable at 92%.

    Cancers diagnosed following visits to emergency departments (ED) or emergency admissions (emergency presentations) are associated with poor survival and may result from preventable diagnostic delay. To improve outcomes for these patients, a better understanding is needed about how emergency presentations arise. This study sought to capture patients' experiences of this diagnostic pathway in the English NHS. Eligible patients were identified in a service evaluation of emergency presentations and invited to participate. Interviews, using an open-ended biographical structure, captured participants' experiences of healthcare services before diagnosis and were analysed thematically, informed by the Walter model of Pathways to Treatment and NICE guidance in an iterative process. Twenty-seven interviews were conducted. Three typologies were identified: A: Rapid investigation and diagnosis, and B: Repeated cycles of healthcare seeking and appraisal without resolution, with two variants where B1 appears consistent with guidance and B2 has evidence that management was not consistent with guidance. Most patients' (23/27) experiences fitted types B1 and B2. Potentially avoidable breakdowns in diagnostic pathways caused delays when patients were conflicted by escalating symptoms and a benign diagnosis given earlier by doctors. ED was sometimes used as a conduit to rapid testing by primary care clinicians, although this pathway was not always successful. This study draws on patients' experiences of their diagnosis to provide novel insights into how emergency presentations arise. Through these typologies, we show that the typical experience of patients diagnosed through an emergency presentation diverges significantly from normative pathways even when there is no evidence of serious service failures. Consultations were not a conduit to diagnosis when they inhibited patients' capacity to appraise their own symptoms appropriately and when they resulted in a reluctance to seek

    The risk of recurrence of myocardial infarction (MI) in HIV patients presenting with acute coronary syndrome (ACS) is well known, but there is limited evidence about potential differences in coronary plaques compared to non-HIV patients. In this multicenter case-control study, HIV patients presenting with ACS, with intravascular-ultrasound (IVUS) data, enrolled between February 2015 and June 2017, and undergoing highly active antiretroviral therapy (HAART), were retrospectively compared to non-HIV patients presenting with ACS, before and after propensity score with matching, randomly selected from included centers. Primary end-point was the prevalence of multivessel disease. Secondary end-points were the prevalence of abnormal features at IVUS, the incidence of major-acute-cardiovascular-events (MACE), a composite end point of cardiovascular death, MI, target lesion revascularization (TLR), stent thrombosis (ST), non-cardiac death and target vessel revascularization (TVR). For each end-point, a subgroup analysis was conducted in HIV patients with CD4 cell count <200/mm 3 . Before propensity score, 66 HIV patients and 120 non-HIV patients were selected, resulting in 20 and 40 after propensity score. Patients with multivessel disease were 11 and 17, respectively (p = 0.56). IVUS showed a lower plaque burden (71% vs. 75%, p < 0.001) and a higher prevalence of hyperechoic non-calcified plaques (100% vs. 35%, p < 0.05) in HIV patients; a higher prevalence of hypoechoic plaques (7% vs. 0%, p < 0.05), a higher incidence of MACE (17.4% vs. 9.1% vs. l'8.0%, p < 0.05), MI recurrence (17.2% vs. 0.0% vs. 2.3%, p < 0.05), and ST (6.7% vs. 0.3% vs. 03%, p < 0.05) in HIV patients with CD4 < 200/mm 3 . Our study may provide a part of the pathophysiological basis of the differences in coronary arteries between HIV-positive and HIV-negative patients, suggesting that the former present with peculiar morphological features at IVUS, even after adjustment for clinical variables

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

    The nodal diffusion algorithms used in many production reactor simulation codes are originating from a common ancestry developed in the 1970s, the analytic nodal method (ANM) of the QUANDRY code. However, this original presentation of the ANM is complex and makes difficult the calculation of the nodal coupling matrices. Moreover, QUANDRY is limited to two-energy groups and its generalization to more groups appears laborious. We are presenting a simplified implementation of the ANM requiring only limited programming work. This formulation is consistent with the initial QUANDRY implementation and is easily generalizable to arbitrary G-group problems. A Matlab script is provided to highlight the simplicity of our presentation. For the sake of clarity, our implementation is limited to G-group, 2-D Cartesian geometry

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

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

    Mass-Gathering Medicine studies have identified variables that predict greater patient presentation rates (PPRs) and transport to hospital rates (TTHRs). This is a descriptive report of patients who presented for medical attention at an annual electronic dance music festival (EDMF). At this large, single EDMF in New York City (NYC; New York, USA), the frequency of patient presentation, the range of presentations, and interventions performed were identified. This descriptive report examined consecutive patients who presented to the medical tent of a summertime EDMF held at an outdoor venue with an active, mobile, bounded crowd. Alcohol was available for sale. Entry was restricted to persons 18 years and older. The festival occurred on three consecutive days with a total cumulative attendance of 58,000. Medical staffing included two Emergency Medicine physicians, four registered nurses, and 86 Emergency Medical Services (EMS) providers. Data collected included demographics, past medical history, vital signs, physical exam, drug and alcohol use, interventions performed, and transport decisions. Eighty-four patients were enrolled over 2.5 days. Six were transported and zero died. The ages of the subjects ranged from 17 to 61 years. Forty-three (51%) were male. Thirty-eight (45%) initially presented with abnormal vital signs; four (5%) were hyperthermic. Of these latter patients, 34 (90%) reported ingestions with 3,4-methylenedioxymethamphetamine (MDMA) or other drugs. Eleven (65%) patients were diaphoretic or mydriatic. The most common prehospital interventions were intravenous normal saline (8/84; 10%), ondansetron (6/84; 7%), and midazolam (3/84; 4%). Electronic dance music festivals are a growing trend and a new challenge for Mass-Gathering Medicine as new strategies must be employed to decrease TTHR and mortality. Addressing common and expected medical emergencies at mass-gathering events through awareness, preparation, and early, focused medical interventions may

    Full Text Available This research seeks to relate fibromyalgia and nutritional factors. Objective: to determine the influence of the food habits on the intensity of the symptoms of fibromyalgia patients. Methods: we interviewed 40 female patients, aged 15 to 59, in the clinic of the Hospital pain set of Sorocaba (CHS through about the fibromyalgia clinical picture and their eating habits. Results: the mean duration of symptoms of fibromyalgia among the interviewed patients was 6.75 years. The average impact of fibromyalgia on the quality of life was about 64 measured by the Fibromyalgia Impact Questionnaire. The only food that was related to symptom improvement by the patients was the banana (17.5%. The majority of respondents did not noticed relationship between such foods and modification of disease symptoms. Conclusion: there was not observed association between food intenak and fibromyalgia symptom severity.

    Full Text Available Background: Non-alcoholic Wernicke's encephalopathy and Korsakoff syndrome are greatly underdiagnosed. There are very few reported cases of neuropsychologically documented non-alcoholic Korsakoff syndrome, and diffusion tensor imaging (DTI data are scarce.Methods: We report clinical characteristics and neuropsychological as well as radiological findings from three psychiatric patients (one woman and two men with a history of probable undiagnosed non-alcoholic Wernicke's encephalopathy and subsequent chronic memory problems.Results: All patients had abnormal neuropsychological test results, predominantly in memory. Thus, the neuropsychological findings were compatible with Korsakoff syndrome. However, the neuropsychological findings were not uniform. The impairment of delayed verbal memory of the first patient was evident only when the results of the memory tests were compared to her general cognitive level. In addition, the logical memory test and the verbal working memory test were abnormal, but the word list memory test was normal. The second patient had impaired attention and psychomotor speed in addition to impaired memory. In the third patient, the word list memory test was abnormal, but the logical memory test was normal. All patients had intrusions in the neuropsychological examination. Executive functions were preserved, except for planning and foresight, which were impaired in two patients. Conventional MRI examination was normal. DTI showed reduced fractional anisotropy values in the uncinate fasciculus in two patients, and in the corpus callosum and in the subgenual cingulum in one patient.Conclusions: Non-alcoholic Korsakoff syndrome can have diverse neuropsychological findings. This may partly explain its marked underdiagnosis. Therefore, a strong index of suspicion is needed. The presence of intrusions in the neuropsychological examination supports the diagnosis. Damage in frontotemporal white matter tracts, particularly in the

The impairment of delayed verbal memory of the first patient was evident only when the results of the memory tests were compared to her general cognitive level. In addition, the logical memory test and the verbal working memory test were abnormal, but the word list memory test was normal. The second patient had impaired attention and psychomotor speed in addition to impaired memory. In the third patient, the word list memory test was abnormal, but the logical memory test was normal. All patients had intrusions in the neuropsychological examination. Executive functions were preserved, except for planning and foresight, which were impaired in two patients. Conventional MRI examination was normal. DTI showed reduced fractional anisotropy values in the uncinate fasciculus in two patients, and in the corpus callosum and in the subgenual cingulum in one patient. Conclusions: Non-alcoholic Korsakoff syndrome can have diverse neuropsychological findings. This may partly explain its marked underdiagnosis. Therefore, a strong index of suspicion is needed. The presence of intrusions in the neuropsychological examination supports the diagnosis. Damage in frontotemporal white matter tracts, particularly in the uncinate

    Background -There is controversy regarding outcome of patients with acute myocarditis (AM), and lack of data on how patients admitted with suspected AM are managed. We report characteristics, in-hospital management and long-term outcome of patients with AM based on a retrospective multi-center registry from 19 Italian hospitals. Methods -A total of 684 patients with suspected AM and recent onset of symptoms (70 years and those older than 50 years without coronary angiography were excluded. The final study population comprised 443 patients (median age 34 years, 19.4% female) with AM diagnosed either by endomyocardial biopsy (EMB) or increased troponin plus edema and late gadolinium enhancement at cardiac magnetic resonance (CMR). Results -At presentation, 118 patients (26.6%) had either left ventricular (LV) ejection fraction (EF) presentation and 0% in uncomplicated cases (Log-rank ppresentation had LVEFpresentation. Conclusions -In this contemporary study, overall serious adverse events after AM were lower than previously reported. However, patients with LVEFpresentation were at higher risk compared with uncomplicated cases that had a benign prognosis and low risk of subsequent LV systolic dysfunction.

    Full text: Introduction: Based on the data in the literature and on our 4 year clinical experience applied for the first time in our country hybrid imaging - single photon emission tomography combined with computed tomography (SPECT / CT) it is clear that to obtain comprehensive information about the function and structure of the studied organ; the time for the diagnosis and thus the start of adequate treatment become shorter. The resulting scintigraphic image is with better quality due to CT correction of ‘diffusion’ gamma radiation, which leads to greater diagnostic accuracy. What you will learn: complex imaging method is used mainly in the field of endocrinology, cardiology, oncology, orthopedics, pulmology, neurology, and neurosurgery. It can be prove a given disease by visualization and localization of the organ lesions and determine the stage of the tumor process, to plan the type of subsequent treatment, to follow the effects of the therapy, and to predict the effect of an interventional or miniinvasive surgical procedure. Discussion: The result of the application of the hybrid imaging method is a change in the interpretation of more than half of the studied patients and in the treatment in more than a quarter of them. Conclusion: The clinical indications for SPECT/CT, and evidence of increased diagnostic accuracy compared with self- administered scintigraphic or CT methods are continuous expanded

    The objective of this study was to define the distribution of inhalant allergens in pediatric patients in whom sensitization was diagnosed with a skin prick test (SPT) who had presented with allergic complaints. In addition, the correlation between the inhalant allergens detected on the SPT and the patients' demographic features, diagnosis, and laboratory findings was defined. A total of 1415 children among the 4056 patients who presented at a clinic in the Eastern Anatolia region with allergic complaints and who had undergone an SPT were included in this study. On the SPT, sensitization to grass pollens was found in 60.1%, cereals pollens in 57.2%, and Dermatophagoides farinae in 21.8% of the patients. Furthermore, on the SPT, incidence of asthma development was 3.96 times higher (odds ratio 3.96, 95% CI: 1.77-6.83; P=0.001) in patients who were allergic to Dermatophagoides farinae. In our study, differences were found in the study region compared to data from around the world and other regions in Turkey in terms of the distribution of allergies and variations in allergens in patients diagnosed due to variations in climate and plants.

A 3-year-old CF patient presented for evaluation with complaints of chronic periocular erythema, conjunctival injection, and irritation for 2 years. He was treated for presumed allergic conjunctivitis with no improvement and continued to have overall worsening of symptoms on the right greater than the left eye in a waxing and waning pattern. On presentation to the Bascom Palmer Eye Institute, he was noted to have telecanthus and prominent erythema in the region of the medial canthus. Orbital imaging disclosed a mucocele in the right ethmoid sinus. The patient underwent functional endoscopic sinus surgery, with successful marsupialization of the ethmoidal mucocele, which was found on culture to be infected with E. coli. Post-operatively with continuous pulmonary care, the patient remains free of allergic conjunctivitis and E. coli colonization of the upper airway. This case highlights the importance of analyzing the adjacent sinus in patients with chronic, relapsing allergic conjunctivitis refractory to medical management, particularly in patients with underlying systemic diseases such as CF.Keywords: allergic conjuncitivitis, Escherichia Coli, cystic fibrosis, mucocele

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

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

  16. Presenting quantitative information about decision outcomes: a risk communication primer for patient decision aid developers

    Science.gov (United States)

    2013-01-01

    Background Making evidence-based decisions often requires comparison of two or more options. Research-based evidence may exist which quantifies how likely the outcomes are for each option. Understanding these numeric estimates improves patients’ risk perception and leads to better informed decision making. This paper summarises current “best practices” in communication of evidence-based numeric outcomes for developers of patient decision aids (PtDAs) and other health communication tools. Method An expert consensus group of fourteen researchers from North America, Europe, and Australasia identified eleven main issues in risk communication. Two experts for each issue wrote a “state of the art” summary of best evidence, drawing on the PtDA, health, psychological, and broader scientific literature. In addition, commonly used terms were defined and a set of guiding principles and key messages derived from the results. Results The eleven key components of risk communication were: 1) Presenting the chance an event will occur; 2) Presenting changes in numeric outcomes; 3) Outcome estimates for test and screening decisions; 4) Numeric estimates in context and with evaluative labels; 5) Conveying uncertainty; 6) Visual formats; 7) Tailoring estimates; 8) Formats for understanding outcomes over time; 9) Narrative methods for conveying the chance of an event; 10) Important skills for understanding numerical estimates; and 11) Interactive web-based formats. Guiding principles from the evidence summaries advise that risk communication formats should reflect the task required of the user, should always define a relevant reference class (i.e., denominator) over time, should aim to use a consistent format throughout documents, should avoid “1 in x” formats and variable denominators, consider the magnitude of numbers used and the possibility of format bias, and should take into account the numeracy and graph literacy of the audience.

    To assess psychosocial characteristics, symptoms and reasons for seeking integrative medicine (IM) care in cancer patients presenting to IM clinical practices. A survey of 3940 patients was conducted at 8 IM sites. Patient reported outcome measures were collected and clinicians provided health status data. This analysis compares 353 participants self-identified as cancer patients with the larger noncancer cohort. Mean age of the cancer cohort was 55.0 years. Participants were predominantly white (85.9%), female (76.4%), and well educated (80.5% completed college). For 15.2% of cancer patients, depression scores were consistent with depressive symptoms, and average scores for perceived stress were higher than normal, but neither were significantly different from noncancer patients. The most prevalent comorbid symptoms were chronic pain (39.8%), fatigue (33.5%), and insomnia (23.3%). In the cancer cohort, perceived stress was significantly associated with depression, fatigue, insomnia, pain, and QOL. Cancer patients who chose an IM clinical practice "seeking healthcare settings that address spirituality as an aspect of care" had significantly higher levels of perceived stress, depression, and pain than those not selecting this reason. Demographic characteristics, depression scores, perceived stress scores, and reasons for seeking integrative cancer care were not significantly different between cancer patients and noncancer patients. Perceived stress may be an important indicator of QOL. The association of perceived stress, depression and pain with seeking spirituality suggests that providing IM interventions, such as effective stress management techniques and pastoral or spiritual counseling, may be helpful to patients living with cancer. © The Author(s) 2014.

    The rehabilitative treatment of the patients suffering from knee osteoarthrosis (OA) up-to-date remains one of the most important medical and social problems of modern medicine due to the high prevalence of this disease, heavy morbidity, and the significant deterioration of the quality of the patients' life. The objective of the present study was to evaluate the long-term results of the combined application of radon and extracorporeal shock-wave therapy for the rehabilitation of the patients presenting with knee OA. The study involved 75 patients at the age from 35 to 62 years with the confirmed diagnosis of stage II and III knee osteoarthrosis. They were divided into 3 groups. Those comprising the main group received extracorporeal shock-wave therapy in combination with the treatment based on the use of radon baths. The patients included in the group of comparison were given a course of radon therapy alone while the patients of the control group received the standard treatment including physiotherapy, magnetic therapy, and the use of non-steroidal anti-inflammatory drugs (NSAIDs). The study has demonstrated the high effectiveness of the combined application of the radon baths and extracorporeal shock-wave therapy that was manifested as the substantial decrease of pain intensity, the increased range of motion in the knee joints, and the improvement of the general quality of life. These beneficial effects persisted during a period of up to 12 months. The stable remission was documented in 82% of the patients comprising the main group. The data obtained give reason to recommend the method employed in the present study for the extensive practical application at different stages of medical rehabilitation of the patients presenting with knee osteoarthrosis.

    To report the clinical findings and management of a case of endogenous endophthalmitis in a patient with bacterial endocarditis presenting with a septic metastasis to the iris. Observational case report. Review of clinical findings and treatment. A 37-year-old intravenous drug user hospitalized with bacterial endocarditis secondary to methicillin-sensitive Staphylococcus aureus bacteremia presented with a painful red left eye, hypopyon, and iris abscess. Roth spots were noted in the fundus of the right eye. Aqueous culture was positive for methicillin-sensitive S aureus. The patient was treated with intravitreal, topical, and intravenous antibiotics. The hypopyon and iris abscess resolved within 2 weeks, and the patient achieved a final visual acuity of 20/25 in the left eye. Septic metastasis to the iris is a rare occurrence. To our knowledge this is the first reported case of an iris abscess secondary to bacterial endocarditis.

    Full Text Available Abstract Introduction Seborrheic keratoses are very common findings in elderly patients. However, a sudden onset and dramatic increase in the number and size of these benign lesions deserves special attention, since this may represent the Leser Trélat sign, a rare paraneoplastic cutaneous syndrome. Case presentation A 92-year-old female presented to our clinic with multiple eruptive seborrheic keratoses, which had dramatically increased in size and number over the past two years. A diagnostic work-up revealed an ovarian carcinoma. Hence, cutaneous findings in our patient were consistent with the diagnosis of the Leser-Trélat sign. Conclusion The Leser-Trélat sign may coincide with the diagnosis of occult cancer or follow or precede it by months or years. Practitioners should take cases of eruptive seborrheic keratoses seriously and perform thorough patient examinations.

    Approximately 75% of prescription opioid abusers obtain the drug from an acquaintance, which may be a consequence of improper opioid storage, use, disposal, and lack of patient education. We aimed to determine the opioid storage, use, and disposal patterns in patients presenting to the emergency department (ED) of a comprehensive cancer center. We surveyed 113 patients receiving opioids for at least 2 months upon presenting to the ED and collected information regarding opioid use, storage, and disposal. Unsafe storage was defined as storing opioids in plain sight, and unsafe use was defined as sharing or losing opioids. The median age was 53 years, 55% were female, 64% were white, and 86% had advanced cancer. Of those surveyed, 36% stored opioids in plain sight, 53% kept them hidden but unlocked, and only 15% locked their opioids. However, 73% agreed that they would use a lockbox if given one. Patients who reported that others had asked them for their pain medications (p = 0.004) and those who would use a lockbox if given one (p = 0.019) were more likely to keep them locked. Some 13 patients (12%) used opioids unsafely by either sharing (5%) or losing (8%) them. Patients who reported being prescribed more pain pills than required (p = 0.032) were more likely to practice unsafe use. Most (78%) were unaware of proper opioid disposal methods, 6% believed they were prescribed more medication than required, and 67% had unused opioids at home. Only 13% previously received education about safe disposal of opioids. Overall, 77% (87) of patients reported unsafe storage, unsafe use, or possessed unused opioids at home. Many cancer patients presenting to the ED improperly and unsafely store, use, or dispose of opioids, thus highlighting a need to investigate the impact of patient education on such practices.

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

    Abstract Secondary sclerosing cholangitis in critically ill patients (SSC-CIP) is an important differential diagnosis in patients presenting with cholestasis and PSC-like cholangiographic changes in endoscopic retrograde cholangiography (ERC). As a relatively newly described entity, SSC-CIP is still underdiagnosed, and the diagnosis is often delayed. The present study aims to improve the early detection of SSC-CIP and the identification of its complications. A total of 2633 records of patients who underwent or were listed for orthotopic liver transplantation at the University Hospital Charité, Berlin, were analyzed retrospectively. The clinical presentation and outcome (mean follow-up 62.7 months) of the 16 identified SSC-CIP cases were reviewed. Cholestasis was the first sign of SSC-CIP. GGT was the predominant enzyme of cholestasis. Hypercholesterolemia occurred in at least 75% of the patients. SSC-CIP provoked a profound weight loss (mean 18 kg) in 94% of our patients. SSC-CIP was diagnosed by ERC in all patients. The 3 different cholangiographic features detected correspond roughly to the following stages: (I) evidence of biliary casts, (II) progressive destruction of intrahepatic bile ducts, and (III) picture of pruned tree. Biliary cast formation is a hallmark of SSC-CIP and was seen in 87% of our cases. In 75% of the patients, the clinical course was complicated by cholangiosepsis, cholangitic liver abscesses, acalculous cholecystitis, or gallbladder perforation. SSC-CIP was associated with worse prognosis; transplant-free survival was ∼40 months (mean). Because of its high rate of serious complications and unfavorable prognosis, it is imperative to diagnose SSC-CIP early and to differentiate SSC-CIP from other types of sclerosing cholangitis. Specific characteristics enable identification of SSC-CIP. Early cooperation with a transplant center and special attention to biliary complications are required after diagnosis of SSC-CIP.

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

    Dengue is a common cause of infection in adults in tropical countries. Sepsis is a syndrome of systemic manifestations induced by infection of any organisms; including bacterial, fungal and viral agents. Here, we investigated the diagnosis, management and outcomes of dengue patients presenting with sepsis in a prospective study of community-acquired sepsis in Thailand. From June to December 2015, 874 adult patients (age≥18 years) with suspected or documented community-acquired infection, with ≥3 diagnostic criteria for sepsis according to the Surviving Sepsis Campaign 2012, and within 24 hours of admission were evaluated. Serum was stored and later tested for dengue PCR assays. A total of 126 patients had dengue PCR assays positive (2 DENV-1, 12 DENV-2, 24 DENV-3 and 88 DENV-4), and 5 of them (4%) died. We found that attending physicians suspected dengue infection on admission in 84 patients (67%), and recorded dengue infection as the final diagnosis in 96 patients (76%). Four of five fatal cases were diagnosed and treated as septic shock not due to dengue. In multivariable analysis, there was a trend showing that age≥60 years, hypoxemia and misdiagnosis of dengue by attending physicians were associated with 28-day mortality. A number of adult patients who died of dengue are misdiagnosed as severe sepsis and septic shock. Diagnosis of dengue based on clinical features alone is difficult. Rapid diagnostic tests for dengue may need to be routinely used in adult patients presenting with sepsis and septic shock in tropical countries. This approach could improve diagnosis and management of those patients.

    Cloud detection of satellite imagery is very important for quantitative remote sensing research and remote sensing applications. However, many satellite sensors don't have enough bands for a quick, accurate, and simple detection of clouds. Particularly, the newly launched moderate to high spatial resolution satellite sensors of China, such as the charge-coupled device on-board the Chinese Huan Jing 1 (HJ-1/CCD) and the wide field of view (WFV) sensor on-board the Gao Fen 1 (GF-1), only have four available bands including blue, green, red, and near infrared bands, which are far from the requirements of most could detection methods. In order to solve this problem, an improved and automated cloud detection method for Chinese satellite sensors called OCM (Object oriented Cloud and cloud-shadow Matching method) is presented in this paper. It firstly modified the Automatic Cloud Cover Assessment (ACCA) method, which was developed for Landsat-7 data, to get an initial cloud map. The modified ACCA method is mainly based on threshold and different threshold setting produces different cloud map. Subsequently, a strict threshold is used to produce a cloud map with high confidence and large amount of cloud omission and a loose threshold is used to produce a cloud map with low confidence and large amount of commission. Secondly, a corresponding cloud-shadow map is also produced using the threshold of near-infrared band. Thirdly, the cloud maps and cloud-shadow map are transferred to cloud objects and cloud-shadow objects. Cloud and cloud-shadow are usually in pairs; consequently, the final cloud and cloud-shadow maps are made based on the relationship between cloud and cloud-shadow objects. OCM method was tested using almost 200 HJ-1/CCD images across China and the overall accuracy of cloud detection is close to 90%.

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

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

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

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

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

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

    Standards for patient decision aids require that information and options be presented in a balanced manner; this requirement is based on the argument that balanced presentation is essential to foster informed decision making. If information is presented in an incomplete/non-neutral manner, it can stimulate cognitive biases that can unduly affect individuals' knowledge, perceptions of risks and benefits, and, ultimately, preferences. However, there is little clarity about what constitutes balance, and how it can be determined and enhanced. We conducted a literature review to examine the theoretical and empirical evidence related to balancing the presentation of information and options. A literature search related to patient decision aids and balance was conducted on Medline, using MeSH terms and PubMed; this search supplemented the 2011 Cochrane Collaboration's review of patient decision aids trials. Only English language articles relevant to patient decision making and addressing the balance of information and options were included. All members of the team independently screened clusters of articles; uncertainties were resolved by seeking review by another member. The team then worked in sub-groups to extract and synthesise data on theory, definitions, and evidence reported in these studies. A total of 40 articles met the inclusion criteria. Of these, six explained the rationale for balancing the presentation of information and options. Twelve defined "balance"; the definition of "balance" that emerged is as follows: "The complete and unbiased presentation of the relevant options and the information about those options-in content and in format-in a way that enables individuals to process this information without bias". Ten of the 40 articles reported assessing the balance of the relevant decision aid. All 10 did so exclusively from the users' or patients' perspective, using a five-point Likert-type scale. Presenting information in a side-by-side display form was

    Full Text Available Congenital H-type tracheoesophageal fistula (TEF in adults is a rare presentation and can test the diagnostic acumen of a surgeon, endoscopist, and the radiologist. These undetected fistulas may present as chronic lung disease of unknown origin because repeated aspirations can lead to recurrent lung infections and bronchiectasis. Congenital TEFs should be considered in the diagnosis of infants and young adults with recurrent respiratory distress and/or infections. Here, we present the successful management of this rare case in an adult patient.

  11. Method and apparatus for simultaneously measuring a plurality of spectral wavelengths present in electromagnetic radiation

    An apparatus and method simultaneously measures a plurality of spectral wavelengths present in electromagnetic radiation. A modulatable birefringent optical element is employed to divide a polarized light beam into two components, thereby producing a phase difference in two resulting light beams such that the two beams can be made to interfere with one another when recombined, the interference pattern providing the wavelength information required for the analysis of the incident light. The interferometer thus created performs in a similar manner to a Michelson interferometer, but with no moving parts, and with a resolution dependent on the degree of phase shift introduced by the modulator.

The NMCC facilities have been opened to researchers of other institutions since April 1993. The present status of NMCC is described. Bio-samples (medical samples, plants, animals and environmental samples) have mainly been analyzed by PIXE in NMCC. Small amounts of bio-samples for PIXE are decomposed quickly and easily in a sealed PTFE (polytetrafluoroethylene) vessel with a microwave oven. This sample preparation method of bio-samples also is described. (author)

    We present a graduate science ethics course that connects cases from the historical record to present realities and practices in the areas of social responsibility, authorship, and human/animal experimentation. This content is delivered with mixed methods, including films, debates, blogging, and practicum; even the instructional team is mixed, including a historian of science and a research scientist. What really unites all of the course's components is the experiential aspect: from acting in historical debates to participating in the current scientific enterprise. The course aims to change the students' culture into one deeply devoted to the science ethics cause. To measure the sought after cultural change, we developed and validated a relevant questionnaire. Results of this questionnaire from students who took the course, demonstrate that the course had the intended effect on them. Furthermore, results of this questionnaire from controls indicate the need for cultural change in that cohort. All these quantitative results are reinforced by qualitative outcomes.

  17. A new method for evaluation and correction of thermal reactor power and present operational applications

    Langenstein, M.; Streit, S.; Laipple, B.; Eitschberger, H.

    2005-01-01

    The determination of the thermal reactor power is traditionally be done by heat balance: 1) for a boiling water reactor (BWR) at the interface of reactor control volume and heat cycle. 2) for a pressurised-water reactor (PWR) at the interface of the steam generator control volume and turbine island on the secondary side. The uncertainty of these traditional methods is not easy to determine and can be in the range of several percent. Technical and legal regulations (e.g. 10CFR50) cover an estimated error of instrumentation up to 2% by increasing the design thermal reactor power for emergency analysis to 102 % of the licensed thermal reactor power. Basically the licensee has the duty to warrant at any time operation inside the analyzed region for thermal reactor power. This is normally done by keeping the indicated reactor power at the licensed 100% value. The better way is to use a method which allows a continuous warranty evaluation. The quantification of the level of fulfilment of this warranty is only achievable by a method which: 1) is independent of single measurements accuracies. 2) results in a certified quality of single process values and for the total heat cycle analysis. 3)leads to complete results including 2-sigma deviation especially for thermal reactor power. Here this method, which is called 'process data reconciliation based on VDI 2048 guideline', is presented [1, 2]. This method allows to determine the true process parameters with a statistical probability of 95%, by considering closed material, mass- and energy balances following the Gaussian correction principle. The amount of redundant process information and complexity of the process improves the final results. This represents the most probable state of the process with minimized uncertainty according to VDI 2048. Hence, calibration and control of the thermal reactor power are possible with low effort but high accuracy and independent of single measurement accuracies. Further more, VDI 2048

    Full Text Available Physicians expect a treatment to be more effective when its clinical outcomes are described as relative rather than as absolute risk reductions. We examined whether effects of presentation method (relative vs. absolute risk reduction remain when physicians are provided the baseline risk information, a vital piece of statistical information omitted in previous studies. Using a between-subjects design, ninety five physicians were presented the risk reduction associated with a fictitious treatment for hypertension either as an absolute risk reduction or as a relative risk reduction, with or without including baseline risk information. Physicians reported that the treatment would be more effective and that they would be more willing to prescribe it when its risk reduction was presented to them in relative rather than in absolute terms. The relative risk reduction was perceived as more effective than absolute risk reduction even when the baseline risk information was explicitly reported. We recommend that information about absolute risk reduction be made available to physicians in the reporting of clinical outcomes. Moreover, health professionals should be cognizant of the potential biasing effects of risk information presented in relative risk terms.

  19. Kaposi’s Sarcoma Presenting as Lymphadenopathy in an Immunocompetent Patient

    2016-11-01

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

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

    This is the first report to illustrate the marsupialization as an effective treatment for a Down Syndrome (DS) patient presenting a residual periapical cyst. These cysts occur within the alveolar ridge, usually at the local site of a previously extracted tooth that did not received proper curettage; usually the surgical excision of a cyst and also the vigorous curettage of a socket is very simple, if not for the fact that mentally disabled patients require rapid and non-stressful procedures. The 54-year-old DS patient represented herein received a minimally invasive marsupialization under local anesthesia. Due to the large extent of the lesion, the acrylic resin drain was maintained for 30 days. Through the following period, a daily irrigation of the cystic cavity with saline solution was carried out to prevent a secondary infection within the cystic cavity. A follow-up of 16 months showed no signs of recurrence. Marsupialization of residual periapical cyst is completely effective and safe, even for a DS patient that is considered to be at an advanced age. Marsupialization poses as a minimally invasive choice for mentally disabled patients, even when presenting advanced ages; treatment success was stated by the easy clinical conduct, uneventful postoperative situation and the lack of recurrence along 16 months of follow-up.

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

    Electrical storm (ES) is a life threatening clinical situation. Though a few clinical pointers exist, the occurrence of ES in a patient with remote myocardial infarction (MI) is generally unpredictable. Genetic markers for this entity have not been studied. In the present study, we carried out genetic screening in patients with remote myocardial infarction presenting with ES by next generation sequencing and identified 25 rare variants in 19 genes predominantly in RYR2, SCN5A, KCNJ11, KCNE1 and KCNH2, CACNA1B, CACNA1C, CACNA1D and desmosomal genes - DSP and DSG2 that could potentially be implicated in electrical storm. These genes have been previously reported to be associated with inherited syndromes of Sudden Cardiac Death. The present study suggests that the genetic architecture in patients with remote MI and ES of unstable ventricular tachycardia may be similar to that of Ion channelopathies. Identification of these variants may identify post MI patients who are predisposed to develop electrical storm and help in risk stratification. Copyright © 2018 Indian Heart Rhythm Society.

    Dichotic listening tests were used to determine cerebral hemisphere memory functions in patients with complex partial seizures before, 10 days after, and 1-3 yr after right (RTE) or left (LTE) temporal-lobe excisions. Control subjects were also tested on two occasions. The tests consisted of presenting a series of 12-word lists and 7-word lists alternately to the two ears while backward speech was presented to the other ear. Measures of immediate free recall, final free recall, final cued recall, and serial recall were employed. The results revealed: (a) that both groups of patients were inferior the control group in tests tapping long-term memory functions rather than short-term memory functions, (b) a right-ear advantage for RTE patients at postoperative testing, (c) that the LTE group was more affected by surgery than the RTE group, and (d) a general improvement in recall performance from early to late postoperative testing. Taken together, these results indicate that the present dichotic test can be used as a non-invasive hemisphere memory test to complement invasive techniques for diagnosis of patients considered for epilepsy surgery.

    The importance of the early recognition of shock in patients presenting to emergency departments is well recognized, but at present, there is no agreed practical definition for undifferentiated shock. The main aim of this study was to validate an a priori clinical definition of shock against 28-day mortality. This prospective, observational, cross-sectional, single-center study was conducted in Hong Kong, China. Data were collected between July 1, 2012, and January 31, 2013. An a priori definition of shock was designed, whereby patients admitted to the resuscitation room or high dependency area of the emergency department were divided into 1 of 3 groups-no shock, possible shock, and shock. The primary outcome was 28-day mortality. Secondary outcomes were in-hospital mortality or admission to the intensive or coronary care unit. A total of 111 patients (mean age, 67.2 ± 17.1 years; male = 69 [62%]) were recruited, of which 22 were classified as no shock, 54 as possible shock, and 35 as shock. Systolic blood pressure, mean arterial pressure, lactate, and base deficit correlated well with shock classifications (P definition of undifferentiated shock has been proposed and validated in a group of patients presenting to an emergency department in Hong Kong. This definition needs further validation in a larger population and other settings. Copyright © 2014 Elsevier Inc. All rights reserved.

    Regardless of its volume, hemoptysis is a concerning symptom. Mild hemoptysis and its significance in patients with solid malignancies has not been studied. We conducted a retrospective chart review of patients with solid malignancies who presented for evaluation of mild hemoptysis. In this population, we studied the impact of bronchoscopic findings and endobronchial therapies on overall survival and bleeding recurrence. Patients were categorized into four groups on the basis of the presence or absence of active bleeding and endobronchial disease at the time of initial bronchoscopy: active bleeding with endobronchial lesion (AB/EBL), active bleeding without endobronchial lesion (AB/no-EBL), absence of active bleeding but with endobronchial lesion (no-AB/EBL), and absence of active bleeding and endobronchial lesion (no-AB/no-EBL). Ninety-five of the 112 patients with solid malignancies and mild hemoptysis underwent bronchoscopies. There was a significantly lower median survival time for patients with bronchoscopic findings of active bleeding and endobronchial lesion compared with patients with no active bleeding and/or no endobronchial lesion (3.48 mo; 95% confidence interval [CI], 2.14-6.05). On a multivariate analysis, factors independently associated with improved survival were higher hemoglobin values (hazard ratio [HR], 0.78; 95% CI, 0.67-0.91) and cessation of hemoptysis without recurrence at 48 hours (HR, 0.43; 95% CI, 0.22-0.84). Variables independently associated with worse survival were disease stage (HR, 10.8; 95% CI, 2.53-46.08) and AB/EBL (HR, 3.20; 95% CI, 1.74-5.89). In patients with solid malignancies presenting with mild hemoptysis, bronchoscopic findings of AB/EBL are associated with decreased survival. Hemoptysis control without recurrence at 48 hours after endobronchial intervention may improve survival.

  7. Two Obese Patients with Presumptive Diagnosis of Anaphylactoid Syndrome of Pregnancy Presenting at a Community Hospital.

    2016-07-01

    Anaphylactoid syndrome of pregnancy (ASP) is a rare but extremely serious complication, with an estimated incidence in North America of 1 in 15 200 deliveries. Despite its rarity, ASP is responsible for approximately 10% of all childbirth-associated deaths in the United States. At present, there is no validated biomarker or specific set of risk factors sufficiently predictive of ASP risk to incorporate into clinical practice. Toward the goal of developing a methodology predictive of an impending ASP event for use by obstetricians, anesthesiologists, and other practitioners participating in infant deliveries, physicians encountering an ASP event have been encouraged to report the occurrence of a case and its biologically plausible risk factors. Herein, we report on 2 patients who presented with a presumptive diagnosis of ASP to the delivery unit of a community hospital. Patient One was a 21-year-old, obese (5'11" tall, 250 lbs., BMI 34.9) white female, 1 pregnancy, no live births (G1P0), estimated gestational age (EGA) 40.2 weeks. Patient Two was a 29-year-old, obese (5'7" tall, 307 lbs., BMI 48.1) Hispanic female, second pregnancy, with 1 previous live birth via C-section (G2P1-0-0-1). Her pregnancy was at gestational age 38 weeks plus 2 days. Patient One had 2 possible risk factors: administration of Pitocin to induce labor and post-coital spotting from recent intercourse. Patient Two suffered premature rupture of the placental membranes. Both Patient One and Patient Two had very high body mass indices (BMIs), at the 97th and 99th percentiles, respectively. In the relatively few cases of anaphylactoid syndrome of pregnancy described to date, this is the first report of a possible association with high BMI.

    Objective We used a national otolaryngology practice–based research network database to characterize the utilization of vestibular function testing in patients diagnosed with dizziness and/or a vestibular disorder. Study Design Database review. Setting The Creating Healthcare Excellence through Education and Research (CHEER) practice-based research network of academic and community providers Subjects and Methods Dizzy patients in the CHEER retrospective database were identified through ICD-9 codes; vestibular testing procedures were identified with CPT codes. Demographics and procedures per patient were tabulated. Analysis included number and type of vestibular tests ordered, stratified by individual clinic and by practice type (community vs academic). Chi-square tests were performed to assess if the percentage of patients receiving testing was statistically significant across clinics. A logistic regression model was used to examine the association between receipt of testing and being tested on initial visit. Results A total of 12,468 patients diagnosed with dizziness and/or a vestibular disorder were identified from 7 community and 5 academic CHEER network clinics across the country. One-fifth of these patients had at least 1 vestibular function test. The percentage of patients tested varied widely by site, from 3% to 72%; academic clinics were twice as likely to test. Initial visit vestibular testing also varied, from 0% to 96% of dizzy patients, and was 15 times more likely in academic clinics. Conclusion There is significant variation in use and timing of vestibular diagnostic testing across otolaryngology clinics. The CHEER network research database does not contain outcome data. These results illustrate the critical need for research that examines outcomes as related to vestibular testing. PMID:27371625

    1983-01-01

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

    A 4-year-old girl presented with an intrathoracic tumour that was pleural in origin, invading the right lower lobe. The patient underwent urgent right thoracotomy and surgical excision of the tumour and right lower lobectomy as the tumour was invading that lobe. The histological report initially reported it as a rhabdomyosarcoma, embryonal type, but after consultation it was changed to type III pleuropulmonary blastoma. The patient was treated with chemotherapy but succumbed to the disease 12 months after the diagnosis. Relevant literature on pleuropulmonary blastoma is reviewed.

    Primary lactotroph disinhibition, or stalk effect, occurs when mechanical compression of the pituitary stalk disrupts the tonic inhibition by dopamine released by the hypothalamus. The resolution of pituitary stalk effect-related hyperprolactinemia postoperatively has not been studied in a large cohort of patients. We performed a retrospective review to investigate the time course of recovery of lactotroph disinhibition after transsphenoidal surgery. Medical records were retrospectively reviewed for all patients undergoing transsphenoidal surgery with the senior author from April 2008 to November 2014. Of 556 pituitary adenomas, 289 (52.0%) were eliminated: 77 (13.9%) had an immunohistochemically confirmed prolactinoma, 119 (21.4%) patients had previous surgery, 93 (16.7%) had incomplete medical records, leaving 267 patients (48.0%) for final analysis. Of these patients, 72 (27.0%) had increased serum prolactin levels (≥23.3 ng/mL), suggestive of pituitary stalk effect (maximum prolactin level = 148.0 ng/mL). Patients with stalk effect were more likely than those with normal serum prolactin levels to present with menstrual dysfunction (29.7% vs. 19.4%; P Transsphenoidal surgery can provide durable normalization of serum prolactin levels and related symptoms caused by pituitary stalk compression-related lactotroph disinhibition.

    Accurate prognostic information is important in determining optimal management of patients presenting for evaluation of chest pain. In this study, the ability of exercise thallium-201 myocardial imaging to predict future cardiac events (cardiovascular death or nonfatal myocardial infarction) was correlated with clinical, coronary and left ventricular angiographic and exercise electrocardiographic data in 139 consecutive, nonsurgically managed patients followed-up over a 3 to 5 year period (mean follow-up, 3.7 +/- 0.9), using a logistic regression analysis. Among patients without prior myocardial infarction (100 of 139), the number of myocardial segments with transient thallium-201 defects was the only statistically significant predictor of future cardiac events when all patient variables were evaluated. Among patients with myocardial infarction before evaluation (39 of 139), angiographic ejection fraction was the only significant predictor of future cardiac events when all variables were considered. This study suggests an approach to evaluate the risk of future cardiac events in patients with possible ischemic heart disease

    Aim: To compare the effect of an initial early computed tomography (CT) examination versus standard practice (SP) on the length of hospital stay, diagnostic accuracy, and mortality of adults presenting with acute abdominal pain. Materials and methods: Two hundred and five adults presenting with acute abdominal pain were randomized to undergo an early CT examination or current SP, which comprised supine abdominal and erect chest radiography. One hundred and ninety-eight patients (99 in each arm) were included in the analysis. The primary endpoint was the duration of inpatient stay; secondary endpoints were diagnostic certainty and mortality. Results: There was no significant difference in the length of hospital stay between the two arms (p = 0.20). At randomization 36% (35 of 96) of CT patients and 49% (48 of 98) of SP patients were correctly diagnosed; 24 h after randomization the correct diagnosis had been established in 84% of CT patients and 73% of SP patients. This refinement in diagnostic certainty was significantly better in the CT group (p < 0.001). There was no difference in mortality between the two trial arms (p = 0.31). Conclusion: Early abdominal CT in patients with acute abdominal pain improves diagnostic certainty, but does not reduce the length of hospital stay and 6 month mortality

    Full Text Available Abstract Background The intuitive early diagnostic guess could play an important role in reaching a final diagnosis. However, no study to date has attempted to quantify the importance of general practitioners' (GPs ability to correctly appraise the origin of chest pain within the first minutes of an encounter. Methods The validation study was nested in a multicentre cohort study with a one year follow-up and included 626 successive patients who presented with chest pain and were attended by 58 GPs in Western Switzerland. The early diagnostic guess was assessed prior to a patient's history being taken by a GP and was then compared to a diagnosis of chest pain observed over the next year. Results Using summary measures clustered at the GP's level, the early diagnostic guess was confirmed by further investigation in 51.0% (CI 95%; 49.4% to 52.5% of patients presenting with chest pain. The early diagnostic guess was more accurate in patients with a life threatening illness (65.4%; CI 95% 64.5% to 66.3% and in patients who did not feel anxious (62.9%; CI 95% 62.5% to 63.3%. The predictive abilities of an early diagnostic guess were consistent among GPs. Conclusions The GPs early diagnostic guess was correct in one out of two patients presenting with chest pain. The probability of a correct guess was higher in patients with a life-threatening illness and in patients not feeling anxious about their pain.

    Full Text Available Background. Within the developing world, many personal, sociocultural, and economic factors cause delayed patient presentation, a prolonged interval from initial symptom discovery to provider presentation. Understanding these barriers to care is crucial to optimizing interventions that pre-empt patient delay. Methods. A systematic review was conducted querying: PubMed, Embase, Web of Science, CINAHL, Cochrane Library, J East, CAB, African Index Medicus, and LiLACS. Of 763 unique abstracts, 122 were extracted for full review and 13 included in final analysis. Results. Studies posed variable risks of bias and produced mixed results. There is strong evidence that lower education level and lesser income status contribute to patient delay. There is weaker and, sometimes, contradictory evidence that other factors may also contribute. Discussion. Poverty emerges as the underlying common denominator preventing earlier presentation in these settings. The evidence for sociocultural variables is less strong, but may reflect current paucity of high-quality research. Conflicting results may be due to heterogeneity of the developing world itself. Conclusion. Future research is required that includes patients with and without delay, utilizes a validated questionnaire, and controls for potential confounders. Current evidence suggests that interventions should primarily increase proximal and affordable healthcare access and secondarily enhance breast cancer awareness, to productively reduce patient delay.

    Nonalcoholic fatty liver disease (NAFLD) is likely to replace Hepatitis C as the leading cause of cirrhosis resulting in liver transplantation (LT) within a few years. Unfortunately, due to the lack of established guidelines for the screening of NAFLD in high-risk populations, many patients present with portal hypertension complications as their first manifestation of NAFLD require a LT evaluation. We aimed to investigate what proportion of patients who underwent LT for NAFLD-cirrhosis had knowledge of their liver disease prior to presenting with portal hypertension complications and to identify differences in clinical parameters between those with and without knowledge of preexisting NAFLD. Consecutive patients who underwent LT for NAFLD-cirrhosis at a tertiary referral center were included in the study. Demographic and clinical data at the time of the first LT evaluation visit were collected, and patient knowledge of previous NAFLD was documented. Ascites, variceal bleeding, hepatic encephalopathy, and thrombocytopenia leading to diagnosis of underlying cirrhosis were considered as the presenting symptoms of portal hypertension. A p portal hypertension. The presenting symptoms were new-onset ascites in 61 %, hepatic encephalopathy in 25 %, variceal bleeding in 18 %, thrombocytopenia in 9 %, and other in 9 % (non-exclusive). Patients with no prior knowledge of NAFLD were less likely to have a diagnosis of hypercholesterolemia (30 vs. 50 %, p = 0.035) and had a trend toward having higher MELD scores at the time of the first LT evaluation visit (15 vs. 13.5, p = 0.05) and presenting with encephalopathy (25 vs. 10 %, p = 0.06) compared to those with previous knowledge of NAFLD diagnosis. The majority of patients undergoing liver transplant evaluation for NAFLD-cirrhosis are not aware of underlying NAFLD until they present with features of portal hypertension. New guidelines should consider screening for NAFLD in certain high-risk groups as more

    Full Text Available Normal pressure hydrocephalus (NPH is characterized by gait disturbance, dementia and/or urinary incontinence associated with dilation of ventricular system with normal opening cerebrospinal fluid pressure. Wide scientifical evidence confirms association between NPH and psychiatric symptoms. We selected 35 patients with idiopathic normal pressure hydrocephalus from January 2010 to January 2012 in a Brazilian tertiary hospital and performed a formal psychiatric evaluation to identify psychiatric disorders. Psychiatric disorders were present in 71% of these patients, especially anxiety, depression and psychotic syndromes. NPH patients may develop symptoms with frontal dominance, such as personality changes, anxiety, depression, psychotic syndromes, obsessive compulsive disorder, Othello syndrome; shoplifting and mania. Unusual appearances of NPH symptoms may hinder early diagnosis and consequently proper treatment.

    Full Text Available Background and aims: The property loss and physical injuries due to fire events in buildings demonstrate the necessity of implementation of efficient and performance based fire safety measures. Effective and high efficiency protection is possible when design and selection of protection measures are based on risk assessment. This study aims at presenting a software method to make possible selection and design of building fire safety measures based upon quantitative risk assessment and building characteristics. Methods: based on “Fire Risk Assessment Method for Engineer (FRAME” a program in MATLB software was written. The first section of this program, according to the FRAME method and based on the specification of a building, calculates the potential risk and acceptable risk level. In the second section, according to potential risk, acceptable risk level and the fire risk level that user want, program calculate concession of protective factor for that building.Results: The prepared software make it possible to assign the fire safety measure based on quantitative risk level and all building specifications. All calculations were performed with 0.001 of precision and the accuracy of this software was assessed with handmade calculations. During the use of the software if an error occurs in calculations, it can be distinguished in the output. Conclusion: Application of quantitative risk assessment is a suitable tool for increasing of efficiency in designing and execution of fire protection measure in building. With using this software the selected fire safety measure would be more efficient and suitable since the selection of fire safety measures performed on risk assessment and particular specification of a building. Moreover fire risk in the building can be managed easily and carefully.

    Full text: Purpose: To look at the clinical presentation and treatment outcome of patients with papillary thyroid carcinoma (PTC) and those with follicular thyroid carcinoma (FTC) in our institution. Methods: The records of all patients with papillary or follicular thyroid carcinoma seen at our institution were retrieved. Patients were excluded from this study if they underwent thyroid surgery outside a teaching hospital or presented to us more than 6 months post surgery, had deep external beam therapy (DXT) following surgery or a follow up of less than 3 years. This left clinical data and treatment outcomes of 140 patients available for a retrospective review. Results: One hundred and seventeen patients were females and 23 were males (5.1:1) with a median follow up of 10,5 years. The differences noted were as follow: there was a higher incidence of PTC than FTC (2.9:1); patients with PTC were younger at presentation (mean age 40 vs 49); more patients with PTC had metastases (60% vs 40%) and were much younger at presentation as compared to those with FTC (mean age 38 vs 63); at presentation eighty percent of FTC metastases were localized in bones whereas 60% of PTC metastases went to the lungs and 36% were confined to local lymph nodes. Similar pattern was found in those who developed metastases later. A significant percentage of ablation failure (41% vs 59% success rate) after the first high dose (2.96-3.7 GBq) of radioactive iodine (RAI) was noted. The total success rate increased to 80% after the second dose of RAI (3.7- 7.4 GBq). The majority of the patients ablated by the second dose had PTC and most had inadequate initial surgery ranging from unilateral lobectomy (10 patients), subtotal thyroidectomy (10 patients), and bilateral lobar resection (1 ). Conclusion: The predominance of PTC over FCT may indicate the conversion to an iodine repletion state in the country as a whole. Similar studies in other regions seem necessary to support this statement. The high

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

    Status epilepticus is a life-threatening, time-sensitive emergency. Acquiring an electroencephalogram (EEG) in the emergency department (ED) could impact therapeutic and disposition decisions for patients with suspected status epilepticus. The objective of this study is to estimate the proportion of EEGs diagnostic for seizures in patients presenting to an ED with a complaint of seizures. This retrospective chart review included adults presenting to the ED of an urban, academic, tertiary care hospital with suspected seizures or status epilepticus, who received an EEG within 24 hours of hospital admission. Data abstraction was performed by a single, trained, nonblinded abstractor. Seizures were defined as an epileptologist's diagnosis of either seizures or status epilepticus on EEG. The proportion of patients with seizures is given with confidence interval95 (CI95). Of 120 included patients, 67 (56%) had a history of epilepsy. Mean age was 52 years (SD, 16), 58% were White, and 61% were male. Within 24 hours, 3% had an EEG diagnostic for seizures. Electroencephalogram was obtained in the ED in 32 (27%) of 120 (CI95, 19%-35%), and 2 (6%) of 32 (CI95, 1%-19%) had seizures. Electroencephalogram was performed inpatient for 88 (73%) of 120 (CI95, 65%-81%), and 2 (2%) of 88 (CI95, 0.5%-7.1%) had seizures. Only 3% of ED patients with suspected seizures or status epilepticus had EEG confirmation of seizures within 24 hours. Early EEG acquisition in the ED may identify a group of patients amenable to ED observation and subsequent discharge from the hospital. Copyright © 2014 Elsevier Inc. All rights reserved.

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

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

    Diabetes Mellitus is emerging as a major health challenge with the incidence and prevalence of the disease on the increase. It also contributes to overall morbidity and mortality with complications like cardiovascular disease, neuropathy, nephropathy, retinopathy and lower extremity amputation. There are few local studies on the clinical characteristics of the disease in our wet up and this study therefore set out to characterize the clinical profile of newly presenting diabetic patients in a health facility in Nigeria. It is a cross sectional, descriptive study carried out at the diabetes clinic of the University of Uyo Teaching Hospital between January 2007 and September 2008. Data obtained included age, sex, anthropometric indices, symptomatology, co-morbidities, complications and treatment of diabetes. Data was analyzed using SPSS version 10. A total of two hundred and seventy patients were studied (120 males, 150 females). About 89.2% were Type 2 DM patients and majority of the study subjects were overweight. Diabetic neuropathy was the commonest complication present in 38.8% of the subjects. Polyuria was the commonest symptom and hypertension the commonest comorbidity. Majority of the subjects were on oral hypolgycaemic agents for the management of their disease with the sulphonyureas and biguanides being the most common medication that was taken by them. A few of the patients were also taking herbal medication for treatment of their disease. Majority of the patients presenting in our facility have Type 2 diabetes, were hypertensive and overweight. Hypertension was the commonest co-morbidity and diabetic neuropathy the commonest complication. Adequate health education, subsidies on medications and proper funding of the health sector is necessary to stem the tide of the burden attributable to the disease. (author)

    Full Text Available We present a case of a patient with a failed pancreaticoduodenal allograft with exocrine enteric-drainage who developed catastrophic gastrointestinal (GI hemorrhage. Over the course of a week, she presented with recurrent GI bleeds of obscure etiology. Multiple esophago-gastro-duodenoscopic (EGD and colonoscopic evaluations failed to reveal the source of the hemorrhage. A capsule endoscopy and a technetium-labeled red blood cells (RBC imaging study were similarly unrevealing for source of bleeding. She subsequently developed hemorrhagic shock requiring emergent superior mesenteric arteriography. Run off images revealed an external iliac artery aneurysm with fistulization into the jejunum. Coiled embolization was attempted but abandoned because of hemodynamic instability. Deployment of a covered endovascular stent into the right external iliac artery over the fistula site resulted in immediate hemodynamic stabilization. A high index of suspicion for arterioenteric fistulae is needed for diagnosis of this uncommon but eminently treatable form of GI hemorrhage in this patient population.

    Full Text Available Transient ischemic attack (TIA is a transient neurological deficit of cerebrovascular origin without infarction which may last only for a short period and can have varying presentations. We report a case of 58-year-old male with presenting features of sudden onset transient vertical diplopia and transient rotatory nystagmus which self-resolved within 12 h. Patient had no history of any systemic illness. On investigating, hematological investigations and neuroimaging could not explain these sudden and transient findings. A TIA could possibly explain these sudden and transient ocular findings in our patient. This case report aims to highlight the importance of TIA for ophthalmologists. We must not ignore these findings as these could be warning signs of an impending stroke which may or may not be detected on neuroimaging. Thus, early recognition, primary prevention strategies, and timely intervention are needed.

    Full Text Available Abstract Background Persistent dyspnea is a common finding in the cystic fibrosis patient that typically leads to further work up of an alternative pulmonary etiology. Adult cystic fibrosis patients; however, are growing in numbers and they are living into the ages in which coronary artery disease becomes prevalent. Coronary disease should be included in the consideration of diagnostic possibilities. Case presentation A 52-year-old white male with cystic fibrosis was evaluated for exertional dyspnea associated with vague chest discomfort. Diagnostic testing revealed normal white blood cell, hemoglobin and platelet count, basic metabolic panel, fasting lipid profile, HbA1c, with chest radiograph confirming chronic cystic findings unchanged from prior radiographs and an electrocardiogram that revealed sinus rhythm with left anterior fascicular block. Stress thallium testing demonstrated a reversible anteroseptal perfusion defect with a 55% left ventricular ejection fraction. Heart catheterization found a 99% occlusion of the left anterior descending artery extending into the two diagonal branches, with 100% obstruction of the left anterior descending artery at the trifurcation and 70% lesion affecting the first posterior lateral branch of the circumflex artery. Conclusion This case report represents the first description in the medical literature of a cystic fibrosis patient diagnosed with symptomatic coronary artery disease. Applying a standard clinical practice guide proved useful toward evaluating a differential diagnosis for a cystic fibrosis patient presenting with dyspnea and chest discomfort.

    The evaluation of patients presenting with audiovestibular symptoms usually includes MRI of the internal auditory meatus, the cerebellopontine angle and the brain. A significant percentage of these scans will present unexpected, incidental findings, which could have important clinical significance. To determine the frequency and clinical significance of incidental findings on MRI scans of patients with audiovestibular symptoms. A retrospective analysis of 200 serial MRI scans. Gender distribution: equal. Age range: 17-82 years. One-hundred and four scans (52%) were normal and 1 scan (0.5%) demonstrated a unilateral vestibular schwannoma. Ninety-five scans (47.5%) demonstrated incidental findings. Sixty-six of these (33%) were considered of ishaemic origin and did not require further action. Five (2.5%) scans demonstrated significant findings which warranted appropriate referral; Two Gliomas (1%), 2 cases of extensive White Matter Lesions (1%), 1 lipoma (0.5%). The remaining scans demonstrated various other findings. Investigation of patients with audiovestibular symptoms with MRI scans revealed incidental findings in a significant percentage (47.5%). The majority of these findings were benign warranting no further action and only 2.5% required further referral. It is the responsibility of the referring Otolaryngologist to be aware of these findings, to be able to assess their significance, to inform the patient and if needed to refer for further evaluation.

    To compare sonography and mammography in terms of their diagnostic value in breast cancer cases which initially presented as an axillary mass without a palpable mass or other clinical symptoms. Seven patients with enlarged axillary lymph nodes who first presented with no evidence of palpable breast lesions and who underwent both mammography and sonography were enrolled in this study. In six of the seven, the presence of metastatic adenocarcinoma was confirmed preoperatively by axillary needle aspiration biopsy; in four, subsequent sonographically guided breast core biopsy performed after careful examination of the primary site indicated that primary breast cancer was present. In each case, the radiologic findings were evaluated by both breast sonography and mammography. Breast lesions were detected mammographically in four of seven cases (57%); in three of the four, the lesion presented as a mass, and in one as microcalcification. In three of these four detected cases, fatty or scattered fibroglandular breast parenchyma was present; in one, the parenchyma was dense. In the three cases in which lesions were not detected, mammography revealed the presence of heterogeneously dense parenchyma. Breast sonography showed that lesions were present in six of seven cases (86%); in the remaining patient, malignant microcalcification was detected at mammography. Final pathologic examination indicated that all breast lesions except one, which was a ductal carcinoma in situ, with microinvasion, were infiltrating ductal carcinomas whose size ranged from microscopic to greater than 3 cm. At the time of this study, all seven patients were alive and well, having been disease free for up to 61 months after surgery. In women with a palpable axillary mass confirmed as metastatic adenocarcinoma, breast sonography may be a valuable adjunct to mammography

    Conventional radiography has been for decades the standard method of evaluation for cervical spine trauma patients. However, currently available helical multidetector CT scanners allow multiplanar reconstruction of images, leading to increased diagnostic accuracy. The purpose of this study was to determine the relative benefit/risk ratio between cervical spine CT and cervical spine radiography and between cervical spine CT and cervical spine radiography, followed by CT as an adjunct for positive findings. A decision analysis model for the determination of the optimum imaging technique was developed. The sensitivity and specificity of CT and radiography were obtained by dedicated meta-analysis. Lifetime attributable risk of mortal cancer from CT and radiography was calculated using updated organ-specific risk coefficients and organ-absorbed doses. Patient organ doses from radiography were calculated using Monte Carlo techniques, simulated exposures performed on an anthropomorphic phantom, and thermoluminescence dosimetry. A prospective patient study was performed regarding helical CT scans of the cervical spine. Patient doses were calculated based on the dose-length-product values and Monte Carlo-based CT dosimetry software program. Three groups of patient risk for cervical spine fracture were incorporated in the decision model on the basis of hypothetical trauma mechanism and clinical findings. Radiation effects were assessed separately for males and females for four age groups (20, 40, 60, and 80 yr old). Effective dose from radiography amounts to 0.050 mSv and from a typical CT scan to 3.8 mSv. The use of CT in a hypothetical cohort of 10{sup 6} patients prevents approximately 130 incidents of paralysis in the low risk group (a priori fracture probability of 0.5%), 500 in the moderate risk group (a priori fracture probability of 2%), and 5100 in the high risk group (a priori fracture probability of 20%). The expense of this CT-based prevention is 15-32 additional

    Focal hypoechoic lesions in the spleen often represent malignant disease in patients with acquired immune deficiency syndrome (AIDS). However, some infection can produce similar images. The abdominal ultrasound imaging about disseminated Penicillium marneffei (P. marneffei) infection has been rarely described in the medical literature. This case report presents a 47-year-old Chinese man with newly diagnosed AIDS who was infected by P. marneffei. An isolated splenic lesion was detected by ultrasound scan before, and assessed following, diagnostic treatment.

    Reported is the case of a 68-year-old male presenting with severe wrist and hand stiffness following surgery for a Dupuytren's contracture. Complications of surgery or rehabilitation and complex regional pain syndrome were excluded as factors explaining this stiffness. Given the patient's diabetes mellitus and the striking similarity with the typical diabetic stiff hand, it is suggested that diabetes may have contributed to the development of the complication.

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

    Brain tuberculosis is still prevalent in many developing countries, especially Asian countries. Tuberculomas should always be considered in the differential diagnosis of enhancing intra-axial lesions of the brain. Brain tuberculomas can present in many different clinical and radiological patterns clinically like headache, fits, cranial nerve palsies and very rarely as brain tuberculomas. We describe the case of a 48 years old male patient presenting with persistent headache and fits, referred for workup of brain metastasis or primary brain neoplasm. On further imaging, it turned out to be multiple tuberculomas of brain which resolved on anti-tuberculous treatment along with symptoms relief. (author)

    To characterise the Emergency Department (ED) prevalence of cellulitis, factors predicting oral antibiotic therapy and the utility of the Clinical Resource Efficiency Support Team (CREST) guideline in predicting patient management in the ED setting, a prospective, cross-sectional study of consecutive adult patients presenting to 3 Irish EDs was performed. The overall prevalence of cellulitis was 12 per 1,000 ED visits. Of 59 patients enrolled, 45.8% were discharged. Predictors of treatment with oral antibiotics were: CREST, Class 1 allocation (odds ratio (OR) 6.81, 95% Cl =1.5-30.1, p=0.012), patient self-referral (OR= 6.2, 95% Cl 1.9- 20.0, p=0.03) and symptom duration longer than 48 hours (OR 1.2, 95% Cl = 1.0-1.5,p=0.049). In conflict with guideline recommendation, 43% of patients in CREST Class 1 received IV therapy. Treatment with oral antibiotics was predicted by CREST Class 1 allocation, self-referral, symptom duration of more than 48 hours and absence of pre-EO antibiotic therapy.

    The objective of this study was to bridge the knowledge gap and improve our understanding of the late presentation and management of breast cancer among South Asian women of non-oriental origin (SA) living in the United Kingdom. Retrospective review of the breast cancer waiting list data-base held at Calderdale and Huddersfield NHS trust was undertaken to identify SA women diagnosed with breast cancer from January 2000 to August 2007. We identified 41 (2.5%) SA women among 1,630 patients diagnosed with breast cancer during this period and 36 were included (median age=53.5 years, range=32-84). Only 19% (n=7) were screen detected and 81% (n=29) presented thorough symptomatic breast clinic. In the latter, 66% (n=19) were in the screening age group and 45% (n=13) presented beyond 8 weeks (late presentation). In our cohort, 91% (n=29) patients had advanced disease (TNM stage 2 and 3) resulting in a high mastectomy rate of 61% (n=22). 19% (n=7) died as a direct result of cancer and the remaining 78% (n=28) remains disease free following treatment thus far. The delay in presentation and poor national breast screening programme uptake among the SA women resulted in advanced disease at diagnosis. There is need for increasing the breast cancer awareness as well as encouraging breast screening among SA women in the UK.

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

    Nocardia are ubiquitous, aerobic, gram-positive actinomycetes. Nocardiosis typically occurs in immunocompromised patients, although immunocompetent individuals can also be affected. The purpose of this case study is to review the clinical characteristics and treatments of a unique form of cutaneous nocardiosis. We retrospectively reviewed the medical literature using PubMed, searching the terms cutaneous, host, immunocompromised, Nocardia, primary, yamanashiensis. Patient reports and previous reviews of the subject were critically assessed and the salient features are presented. Cutaneous nocardiosis typically presents as pustular nodules and the lesions may progress to become abscesses, cellulitis, granulomas or keloid-like tumors. N. brasiliensis is the predominant species involved in primary cutaneous nocardiosis; other common Nocardia species involved in human disease are N. farcinica, N. abscessus, N. cyriacigeorgica, and N. nova. Only two individuals (including the patient presented here) with primary cutaneous infection by N. yamanashiensis have been described in the literature; a third clinical isolate was recovered from a lung biopsy. Nocardia yamanashiensis is a rare clinical form of primary cutaneous nocardiosis. 16S ribosomal gene sequencing, as well as Gram stain and modified Fite acid-fast stain, play a vital role in identifying this clinical variant.

  4. Multiple cavernous malformations presenting in a patient with Poland syndrome: A case report

    2011-09-01

    Full Text Available Abstract Introduction Poland syndrome is a congenital disorder related to chest and hand anomalies on one side of the body. Its etiology remains unclear, with an ipsilateral vascular alteration (of unknown origin to the subclavian artery in early embryogenesis being the currently accepted theory. Cavernous malformations are vascular hamartomas, which have been linked to a genetic etiology, particularly in familial cases, which commonly present with multiple lesions. Our case report is the first to describe multiple cavernous malformations associated with Poland syndrome, further supporting the vascular etiology theory, but pointing to a genetic rather than a mechanistic factor disrupting blood flow in the corresponding vessels. Case presentation A 41-year-old Caucasian man with Poland syndrome on the right side of his body presented to our hospital with a secondary generalized seizure and was found to have multiple cavernous malformations distributed in his brain, cerebellum, and brain stem, with a predominance of lesions in the left hemisphere. Conclusion The distribution of cavernous malformations in the left hemisphere and the right-sided Poland syndrome in our patient could not be explained by a mechanistic disruption of one of the subclavian arteries. A genetic alteration, as in familial cavernous malformations, would be a more appropriate etiologic diagnosis of Poland syndrome in our patient. Further genetic and pathological studies of the involved blood vessels in patients with Poland syndrome could lead to a better understanding of the disease.

    To find out the frequency of patients attending Casualty department of a Teaching Hospital with sudden severe thunderclap headache, their diagnostic out-come and follow up. The study was conducted in Casualty and Medical, Departments of Saidu Teaching Hospital, Saidu Sharif, from January 2006 to December 2006. Out of 22,000 patients with different Medical problems attended Casualty department during study period of which 128 cases had acute severe thunderclap headache. Age range was 15 to 80 years with mean age of 46+-10 years. Seventy eight patients (61%) were female and fifty (39%) were male. Protocol included proper clinical examination, basic laboratory investigations, admission to the General medical ward / Intensive care unit for observation, treatment and follow-up. CT scan of brain and or lumber puncture was performed in all the studied patients. The in-hospital follow up period was from two to fourteen days. The patients were reviewed one month later after discharge from hospital. Out of 120 patients twenty cases (15.6%) had Subarachnoid haemorrhage (SAH) seven patients (5.4%) had Cerebral infarction, five patients (3.9%) had an Intracerebral Haematoma. Five patients (3.9%) had aseptic meningitis. Two cases (1.5%) were reported as cerebral edema. One case (0.8%) had venous sinus thrombosis. As there was no specific finding on investigations and follow up of 88 cases (69%): these were labeled as idiopathic thunder-clap headache. Past history of not more than three similar episodes was present in 33 cases (25.78%). Out of these 33 cases, thirty belonged to the benign group of 88; other three cases had organic causes. Clinical diagnosis of Migraine was made in 37 cases out of these 88 cases. Attack of severe thunderclap headache is not an un-common emergency. Attack due to Subarachnoid haemorrhage (SAH) or other serious underlying disease cannot be distinguished from non specific headaches on clinical grounds alone. It is recommended that all such patients be

Study Design: Observational study. Place and Duration of Study: King Edward Medical University, Lahore and Hameed Latif Hospital, Lahore, from February 2013 to March 2014. Methodology: A total of 50 newly diagnosed and untreated patients of ALL were selected from Mayo Hospital and Hameed Latif Hospital. These patients included both genders and all age groups. Hemoglobin, total leukocyte count and platelet count were determined on hematology analyser-Sysmex-Kx-2I. Blast cell percentage was estimated on Giemsa stained blood smears. Immuno phenotyping was done on bone marrow samples by 5 colour flow cytometery on Beckman Counter Navious Flow cytometer. An acute leukemia panel of 23 antibodies was used. The data was entered and analyzed in SPSS version 22. Results: Of the 50 ALL patients, 36 (72 percentage) were B-ALL and 14 (28 percentage) T-ALL. There were 18 (36 percentage) children and 32 (64 percentage) adults. T-ALL included 22 percentage of the childhood and 31 percentage of the adult cases. Immuno phenotypic analysis showed that CD19, CD79a and CD20 were B-lineage specific markers whereas cCD3, CD3 and CD5 were T-lineage specific. CD10 was the most sensitive marker for B-ALL and CD7 was the most sensitive marker of T-ALL. TdT was expressed in 92 percentage B-ALL and 71 percentage T-ALL cases, CD34 in 58 percentage and 43 percentage cases and CD45 in 83 percentage and 100 percentage respectively. High leukocyte count (> 50 x 109/L) was present in 58 percentage cases. Hemoglobin was < 10 g/dl in 74 percentage patients and platelet count was below 20 x 109/Lin 12 percentage patients. Leukocyte count, hemoglobin, platelet count and blast cell percentage did not show a significant difference in the two ALL immuno types. Conclusion: The frequency of T-ALL is higher in childhood

    Neil Armstrong's understated words, "That's one small step for man, one giant leap for mankind." were spoken from Tranquility Base forty years ago. Even today, those words resonate in the ears of millions, including many who had yet to be born when man first landed on the surface of the moon. By their very nature, and in the the spirit of exploration, extravehicular activities (EVAs) have generated much excitement throughout the history of manned spaceflight. From Ed White's first space walk in June of 1965, to the first steps on the moon in 1969, to the expected completion of the International Space Station (ISS), the ability to exist, live and work in the vacuum of space has stood as a beacon of what is possible. It was NASA's first spacewalk that taught engineers on the ground the valuable lesson that successful spacewalking requires a unique set of learned skills. That lesson sparked extensive efforts to develop and define the training requirements necessary to ensure success. As focus shifted from orbital activities to lunar surface activities, the required skill-set and subsequently the training methods, changed. The requirements duly changed again when NASA left the moon for the last time in 1972 and have continued to evolve through the Skylab, Space Shuttle; and ISS eras. Yet because the visits to the moon were so long ago, NASA's expertise in the realm of extra-terrestrial EVAs has diminished. As manned spaceflight again shifts its focus beyond low earth orbit, EVA success will depend on the ability to synergize the knowledge gained over 40+ years of spacewalking to create a training method that allows a single crewmember to perform equally well, whether performing an EVA on the surface of the Moon, while in the vacuum of space, or heading for a rendezvous with Mars. This paper reviews NASA's past and present EVA training methods and extrapolates techniques from both to construct the basis for future EVA astronaut training.

    Full Text Available BACKGROUND Diabetic eye disease can lead to permanent visual impairment or blindness if medical attention is delayed. Awareness and knowledge of diabetes-related eye complications is important for early medical presentation and maximisation of visual prognosis. The aim of the study is to study the level of awareness and knowledge of diabetic eye disease among diabetic patients presenting to eye OPD in central India. MATERIALS AND METHODS A hospital-based study was conducted on 300 diabetic patients presenting to eye OPD. A questionnaire was provided to the patients based on their awareness and knowledge of diabetic eye disease. On the basis of their response, answers were categorised into three groups for awareness (fully, partially and not aware and for knowledge (good, fair and poor knowledge. RESULTS Out of 300, the mean age of participants was 50.3 ± 12.4 years (range 20-79 years from which 123 (41% were males and 177 (59% were females. 106 (35.3% were from rural area and 194 (64.7% were from urban area. 164 (54.7% were literate and 136 (45.3% were illiterate. Maximum patients 172 (57.3% were diabetic since last 5 years with the average duration being 5.9 ± 4.1 years. Out of 300 patients, only 89 (29.7% were found to be fully aware and only 66 (22.0% had good knowledge (p<0.001. There was little knowledge of retinopathy risk factors or the need for routine eye examination. Most of the patients 152 (50.7% were not advised by their physician for screening. CONCLUSION The present study showed that there is poor awareness and knowledge among a larger portion of the sample among the illiterate patients, patients from rural area and those who were recently diagnosed diabetics. There is therefore a need for increasing awareness about diabetes in patients and physicians and providing access to retinopathy screening services to the patients.

    The objective of this study is to evaluate the effect of music therapy on pain, anxiety, and patient satisfaction in patients who present to the emergency department in Turkey. This controlled and experimental study was conducted in the emergency department of a hospital in Turkey between July and October 2012. The study sample consisted of 200 patients in total, 100 forming the intervention group and 100 being the control group, who fell under color code green in the triage system and came with complaints of pain due to nausea/vomiting and diarrhea, abdominal pain, headaches, and joint pain. A questionnaire, the State Anxiety Scale, and the Visual Analog Scale to measure the patients' level of pain were used in the study. The questionnaires of the intervention group were administered after playing the music. When the intervention and control groups were compared, it was observed that there was a significant decrease in the VASP and STAI-S scores in favor of the intervention group. It was observed that 21.0% of the patients in the intervention group were very pleased to hear music in the emergency department, 58% of them were moderately or at least a little pleased, and 21.0% were not pleased at all. The results showed that music therapy had a positive effect in terms of reducing the severity of pain and the level of anxiety in patients, that only a very small portion of the patients were not pleased to listen to music in the emergency department. © 2014 The Authors.

    Graphic prints and manuscripts constitute main part of the cultural heritage objects created by the most of the known civilizations. Their presentation was always a problem due to their high sensitivity to light and changes of external conditions (temperature, humidity). Today it is possible to use an advanced digitalization techniques for documentation and visualization of mentioned objects. In the situation when presentation of the original heritage object is impossible, there is a need to develop a method allowing documentation and then presentation to the audience of all the aesthetical features of the object. During the course of the project scans of several pages of one of the most valuable books in collection of Museum of Warsaw Archdiocese were performed. The book known as "Great Dürer Trilogy" consists of three series of woodcuts by the Albrecht Dürer. The measurement system used consists of a custom designed, structured light-based, high-resolution measurement head with automated digitization system mounted on the industrial robot. This device was custom built to meet conservators' requirements, especially the lack of ultraviolet or infrared radiation emission in the direction of measured object. Documentation of one page from the book requires about 380 directional measurements which constitute about 3 billion sample points. The distance between the points in the cloud is 20 μm. Provided that the measurement with MSD (measurement sampling density) of 2500 points makes it possible to show to the publicity the spatial structure of this graphics print. An important aspect is the complexity of the software environment created for data processing, in which massive data sets can be automatically processed and visualized. Very important advantage of the software which is using directly clouds of points is the possibility to manipulate freely virtual light source.

    Artificial neural networks (ANNs) are computer programs used to identify complex relations within data. Routine predictions of presence of colorectal pathology based on population statistics have little meaning for individual patient. This results in large number of unnecessary lower gastrointestinal endoscopies (LGEs - colonoscopies and flexible sigmoidoscopies). We aimed to develop a neural network algorithm that can accurately predict presence of significant pathology in patients attending routine outpatient clinics for gastrointestinal symptoms. Ethics approval was obtained and the study was monitored according to International Committee on Harmonisation - Good Clinical Practice (ICH-GCP) standards. Three-hundred patients undergoing LGE prospectively completed a specifically developed questionnaire, which included 40 variables based on clinical symptoms, signs, past- and family history. Complete data sets of 100 patients were used to train the ANN; the remaining data was used for internal validation. The primary output used was positive finding on LGE, including polyps, cancer, diverticular disease or colitis. For external validation, the ANN was applied to data from 50 patients in primary care and also compared with the predictions of four clinicians. Clear correlation between actual data value and ANN predictions were found (r = 0.931; P = 0.0001). The predictive accuracy of ANN was 95% in training group and 90% (95% CI 84-96) in the internal validation set and this was significantly higher than the clinical accuracy (75%). ANN also showed high accuracy in the external validation group (89%). Artificial neural networks offer the possibility of personal prediction of outcome for individual patients presenting in clinics with colorectal symptoms, making it possible to make more appropriate requests for lower gastrointestinal endoscopy. © 2010 The Authors.

    The objective of this study was to investigate the clinical and ultrasonographic findings of women who had three-dimensional endovaginal ultrasound (EVUS) for the management of vaginal mesh complications. This was a retrospective study of patients that had EVUS due to mesh complications at a tertiary care center. The clinical charts were reviewed. The stored 3D volumes were reviewed regarding mesh information by two examiners independently. The predictive value of physical examination for detection of vaginal mesh was calculated. Patient outcomes were reviewed. Seventy-nine patients presented to our center because of their, or their physicians' concern regarding mesh complications. Forty-one (51.9%) had vaginal/pelvic pain, and 51/62 (82.2%) of sexually active women experienced dyspareunia. According to ultrasonographic findings, mesh or sling was not demonstrated in six patients who believed they have had mesh/sling implantation. The positive predictive value for vaginal examination was 94.5% (95% CI: 84.9%-98.8%), negative predictive value was 12.5% (95% CI: 2.8%-32.4%), sensitivity was 72.2% (95% CI: 59.4%-81.2%), and specificity was 50.0% (95% CI: 12.4%-87.6%). Fifty-four patients were indicated for surgical treatment. Median postoperative review was 12 (range, 3-18) months and 38/53 (71.7%) patients were satisfied. The most common complaints of vaginal mesh complications were pain and dyspareunia. EVUS appeared to be helpful for assessing mesh presence, location, and extent including planning for surgical intervention. © 2015 Wiley Periodicals, Inc.

    Patients with upper gastrointestinal bleeding (UGIB) require an early, tailored approach best guided by knowledge of the bleeding lesion, especially a variceal versus a nonvariceal source. To identify, by investigating a large national registry, variables that would be predictive of a variceal origin of UGIB using clinical parameters before endoscopic evaluation. A retrospective study was conducted in 21 Canadian hospitals during the period from January 2004 until the end of May 2005. Consecutive charts for hospitalized patients with a primary or secondary discharge diagnosis of UGIB were reviewed. Data regarding demographics, including historical, physical examination, initial laboratory investigations, endoscopic and pharmacological therapies administered, as well as clinical outcomes, were collected. Multivariable logistic regression modelling was performed to identify clinical predictors of a variceal source of bleeding. The patient population included 2020 patients (mean [± SD] age 66.3±16.4 years; 38.4% female). Overall, 215 (10.6%) were found to be bleeding from upper gastrointestinal varices. Among 26 patient characteristics, variables predicting a variceal source of bleeding included history of liver disease (OR 6.36 [95% CI 3.59 to 11.3]), excessive alcohol use (OR 2.28 [95% CI 1.37 to 3.77]), hematemesis (OR 2.65 [95% CI 1.61 to 4.36]), hematochezia (OR 3.02 [95% CI 1.46 to 6.22]) and stigmata of chronic liver disease (OR 2.49 [95% CI 1.46 to 4.25]). Patients treated with antithrombotic therapy were more likely to experience other causes of hemorrhage (OR 0.44 [95% CI 0.35 to 0.78]). Presenting historical and physical examination data, and initial laboratory tests carry significant predictive ability in discriminating variceal versus nonvariceal sources of bleeding.

    To determine the risk factors for Deliberate Self-Harm (DSH) in patients presenting to the Emergency Departments (EDs) of three tertiary care hospitals of Karachi, Pakistan. Study Design: Multicentre matched case control study. Place and Duration of Study: EDs of the Aga Khan University Hospital, Karachi, Civil Hospital, Karachi and Jinnah Postgraduate Medical Centre, Karachi, from March 2011 to February 2012. Methodology: A total of 201 cases and 201 matched controls were taken from three hospitals situated in Karachi. All patients of 16 years and above presenting to the EDs of the hospitals with DSH attempt were invited to participate in the study. Controls were ED patients with complaints other than DSH. A control was matched with case for hospital, gender and age. Two questionnaires were used to collect information on the risk factors of DSH. Conditional Logistic Regression (CLR) was used to assess the association of various risk factors with DSH. Results: Risk factors of DSH in Karachi included current history of mental disorder (OR = 4.53, 95% CI = 1.59 - 12.92), not sharing problems with someone (OR = 4.67, 95% CI = 2.4 - 9.0), living in rented houses (OR = 2.58, 95% CI = 1.37 - 4.84), Pathan ethnicity (OR = 5.05, 95% CI = 1.01-25.38) followed by others (OR = 3.88, 95% CI = 0.77 - 19.69) and Urdu speaking (OR = 2.71, 95% CI = 0.59 - 12.45). Absence of physical illness in the past month had an inverse association with DSH (OR = 0.17, 95% CI = 0.07 - 0.37). Conclusion: Mental illnesses, low socio-economic status and loneliness were the risk factors of DSH patients presenting to the three EDs of Karachi. Physical illness in the last month was protective against DSH in these patients. Psychiatric evaluation of DSH patients in the ED is important for early diagnosis and management of mental disorders.

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

    Full Text Available Aphasia is an important presenting symptom of acute stroke. With increasing reliance on electronic communication, incoherent texting or “dystextia,” which is a subset of aphasia that is reflected in text messages, can be a useful tool for symptom recognition and analysis. It can be a red flag for the family and therefore can help in early identification of an acute neurological deficit. It is also useful for providers to reliably analyze the deficit as well as establish a timeline of evolution of symptoms. There have been case reports where dystextia has been the presenting feature of stroke or complicated migraine and in one case of meningioma. We present the case of a teenage patient that in our knowledge is the youngest reported case of dystextia, whose aphasia recorded in a text message assisted with stroke localization. This also adds to the literature of dystextia which so far has only seven other cases reported.

    The authors present an unusual case of an acute swelling of the lower lip and septicemia in a 35-year-old, recent immigrant male arriving from India. The patient presented in our emergency department with a 48-hour history of a worsening, painful swelling of the lower lip. On presentation, he was pyrexial and the lip was found to be acutely inflamed with honey-colored crusting, pustular lesions, and induration . A diagnosis of impetigo leading to necrosis of the lip was established, a rare phenomenon potentially resulting in significant tissue destruction. Appropriate medical management achieved a good outcome and prevented disabling tissue loss of the orofacial region. Copyright © 2012 Elsevier Inc. All rights reserved.

    Full Text Available Ventricular noncompaction (VNC of the myocardium is a rare genetic cardiomyopathy caused by a disorder during endocardial morphogenesis and could be accompanied by life-threatening complications. The major clinical manifestations of VNC are heart failure, arrhythmias, and embolic events. The left ventricle is the most commonly reported affected site, but a few cases of right ventricular involvement have also been reported. We report a case of biventricular noncompaction cardiomyopathy in a 31-year-old woman presenting with a new onset seizure. On the second day of her telemetry-monitored hospitalization, she suffered a witnessed ventricular fibrillation arrest requiring emergency direct-current cardioversion and induced hypothermia. Transthoracic echocardiography (TTE showed isolated left ventricular (LV noncompaction and depressed LV systolic function. Subsequent cardiac magnetic resonance imaging (MRI revealed both left and right ventricular noncompaction. This unusual presentation highlights the importance of a complete and thorough evaluation of patients even when presenting with apparently noncardiac symptom(s.

    Osteomalacia is uncommon in an affluent subtropical city like Hong Kong, where sunlight exposure is adequate and nutritional support is good. We present three patients who had osteomalacia with different presentations. A 74-year-old male with oncogenic osteomalacia presented with multiple bone pain. His biochemical markers returned to normal 4 days postoperatively after resection of a second toe giant cell tumour of tendon sheath. A 62-year-old woman with a history of liver problem and proximal muscle weakness was admitted with atraumatic fracture of the left distal humerus due to osteomalacia. An 81-year-old vegetarian woman with inadequate sun exposure complained of multiple bone pains. Subsequent investigation revealed dietary- and sunlight-deficient osteomalacia with multiple bony abnormalities including marked femur bowing.

    Inflammatory bowel disease appears to be uncommon among Asians. This study was conducted to determine the prevalence of ulcerative colitis (UC) in Malaysian patients and to establish the spectrum of the disease seen in Malaysian patients. Three major Asian races: Malay, Chinese, and Indian co-exist in Malaysia and we sought to determine if there were any racial differences in the prevalence and presentation of disease. Racial differences for several other gastrointestinal diseases have previously been observed and found to be extremely interesting. Data were obtained retrospectively from a review of the medical records of in- and out-patients with a diagnosis of UC at the University Hospital, Kuala Lumpur between 1985 and 1998. There were 45 confirmed cases of UC of which 3 were foreigners, who were excluded from analysis. Thirty new cases of UC were diagnosed during the study period. Their mean age at presentation was 33.0+/-10.0 years. The highest prevalence of UC was 17.9/100 000 hospital admissions in the Indians, followed by 11.2/100 000 hospital admissions in the Chinese. The lowest prevalence was 3.7/100 000 hospital admissions in the Malays. The prevalence of UC was significantly higher in the Indians and the Chinese when compared with the Malays with an OR of 4.89 (CI = 2.02-12.24; chi2 = 15.45, PMalaysia, but racial differences exist. The Indians had the highest prevalence of UC with the Chinese demonstrating the least extensive disease.

    Costs are an important component of patients' decision making, but a comparatively underemphasized aspect of formal shared decision making. We hypothesized that decision aids also avoid discussion of costs, despite their being tools designed to facilitate shared decision making about patient-centered outcomes. We sought to define the frequency of cost-related information and identify the common modes of presenting cost and cost-related information in the 290 decision aids catalogued in the Ottawa Hospital Research Institute's Decision Aid Library Inventory (DALI) system. We found that 56% (n = 161) of the decision aids mentioned cost in some way, but only 13% (n = 37) gave a specific price or range of prices. We identified 9 different ways in which cost was mentioned. The most common approach was as a "pro" of one of the treatment options (e.g., "you avoid the cost of medication"). Of the 37 decision aids that gave specific prices or ranges of prices for treatment options, only 2 were about surgery decisions despite the fact that surgery decision aids were the most common. Our findings suggest that presentation of cost information in decision aids is highly variable. Evidence-based guidelines should be developed by the International Patient Decision Aid Standards (IPDAS) Collaboration. © The Author(s) 2015.

    Traffic accidents are ranked first as the cause of personal injury throughout the world. The high number of traffic accidents yielding injuries and fatalities makes them of great importance to Emergency Departments. Patients admitted to Hacettepe University Faculty of Medicine Adult Emergency Department due to traffic accidents were investigated epidemiologically. Differences between groups were evaluated by Kruskall-Wallis, Mann-Whitney, and Wilcoxon tests. A value of paccidents were the most common. In 2004 the rate of traffic accidents (15.3%) was higher than the other years, the most common month was May (10.8%), and the most common time period was 6 pm to 12 am (midnight). About half of the patients (51.5%) were admitted in the first 30 minutes. Life-threatening condition was present in 9.6% of the patients. Head trauma was the most common type of trauma, with the rate of 18.3%. Mortality rate was 81.8%. The average length of hospital stay was 403 minutes (6.7 hours) and the average cost per patient was 983 ± 4364 TL. Further studies are needed to compare the cost found in this study with the mean cost for Turkey. However, the most important step to reduce the direct and indirect costs due to traffic accidents is the prevention of these accidents.

    Several reports have suggested that nitrates limit acute ischaemic damage by a mechanism similar to preconditioning. This study aims to evaluate the effect of chronic oral nitrates on the clinical presentation and short-term outcomes of patients admitted with acute coronary syndrome (ACS). A retrospective cohort study was conducted in patients with ACS admitted to 62 acute care units from 2010 to 2011. A propensity score-matched samples analysis was performed. We analysed 3171 consecutive patients, of whom 298 (9.4%) were chronically treated with nitrates. Patients previously treated with nitrates had higher comorbidity and disease severity at admission, lower prevalence of ACS with ST elevation, lower troponin elevation, higher prevalence of initial Killip class 2-4 and higher hospital mortality. The propensity score-matched analysis confirmed that previous use of nitrates is independently associated with a lower prevalence of ST-elevation ACS [odds ratio (OR) 0.53, 95% confidence interval (CI) 0.36-0.78; P = 0.0014] and a lower troponin elevation (OR 0.61, 95% CI 0.41-0.92) but not with Killip class on admission (OR 1.18, 95% CI 0.83-1.67, P = 0.3697) or mortality (OR 0.71, 95% CI 0.37-1.38, P = 0.3196). The results support the hypothesis that nitrates have a protective effect on acute ischaemic injury.

    The occurrence of a brain tumor or intracranial vascular lesion during pregnancy is a rare event, but when it happens, it jeopardizes the lives of both the mother and infant. It also creates challenges of a neurosurgical, obstetric, and ethical nature. A multidisciplinary approach should be used for their care. Between 1986 and 2015, 12 pregnant women diagnosed with brain tumors and 17 women with intracranial vascular lesion underwent treatment at the Neurosurgery Department of the Servidores do Estado Hospital and Rede D'Or/São Luis. The Neurosurgery Department teamed up with Obstetrics Anesthesiology Departments in establishing the procedures. The patients' records, surgical descriptions, imaging studies, and histopathological material were reviewed. Among 12 patients presenting with brain tumors, there were neither operative mortality nor fetal deaths. Among the vascular lesions, aneurysm rupture was responsible for bleeding in 6 instances. Arteriovenous malformation was diagnosed in 7 patients. In this subgroup, the maternal and fetal mortality rates were 11.7% and 23.7%, respectively. We can assert that the association between a brain tumor and vascular lesions with pregnancy is a very unusual event, which jeopardizes both the lives of the mother and infant. It remains incompletely characterized due to the rare nature of these potentially devastating events. Knowing the exact mechanism responsible for the interaction of pregnancy and with these lesions will improve the treatment of these patients.

    Traditionally, classic KS lesions have a general distribution, often involving the skin of the feet and legs, and to a lesser extent, that of the hands, arms, and trunk. Oral involvement is a rare manifestation. Initial oral involvement is an even rarer occurrence. We report two unusual cases of classic KS presenting in the oral cavity of two patients from indigenous origin; the first patient with primary oral KS lesion on the hard palate, with no other signs of the condition in any other region of the body; the second patient with generalized dermal KS lesions with lymph node and lower lip involvement. In conclusion, clinicians and pathologists should be aware of the typical clinical, gross, and histologic features of KS. Moreover, we would like to emphasize that oral KS may affect patients without AIDS or exposure to immunosuppression. The awareness of oral classic KS as a diagnostic possibility is important in the work-up of vascular lesions in the oral cavity of non-immunosuppressed individuals.

    Osteoarthritis (OA) is currently considered to be one of the most widespread diseases. Its main clinical symptoms include pain and dysfunction of joints. In the present review of the foreign and domestic literature, the questions of pathogenesis and risk factors underlying the development of osteoarthritis are discussed. The understanding of OA pathogenesis have altered essentially in the recent years which made necessary the search for the novel approaches to the treatment of this pathology. According to the modern views of OA origin and progression, its therapy should be based on the application of the combination of medicamentous and non-medicamentous modalities including, in particular, collective and individual activities focused on the implementation of the programs of therapeutic physical training as an obligatory component of ОА prophylaxis and treatment. The present review gives evidence of the feasibility of the application of the methods of cryotherapy and radonotherapy for the management of the patients suffering from osteoarthritis. It is emphasized that many recent publications report extensive investigations of the clinical and pathogenetic aspects of the application of these methods for the combined regenerative treatment of the patients presenting with gonarthrosis. The influence of cryotherapy and radonotherapy on the neuroendocrine and immune systems is discussed with special reference to the possibility of regulation of the metabolic processes and retardation of inflammation. It is concluded that the introduction of the above methods into the compulsory individual program for the regenerative treatment of patients presenting with osteoarthritis is pathologically substantiated since it greatly contributes to the reduction of pain and retardation of the progress of the disease. The main pharmaceutical preparations for the OA treatment remain to be slow-acting symptomatic medicines possessed of the chondro-protective effect.

    The problem of the development of the new efficient methods for the treatment of the patients presenting with chronic bacterial vesiculitis (CBV) is currently considered among the important priorities. The objective of the present study was to provide a scientifically sound substantiation for the application of sinusoidal modulated currents (SMC), magnetic fields, and laser radiation in the combined treatment of the patients with CBV. A total of 121 patients presenting with chronic bacterial vesiculitis were examined and treated during the latent phase of the inflammatory process. They were randomly divided into three groups. Group 1 (main) was comprised of 40 patients treated, in addition to basal pharmacotherapy, by supravascular contact laser irradiation of the cubital vein area followed after 2-3 hours by the application of sinusoidal modulated currents to the pubosacral region. Group 2 included 41patents given, besides basal pharmacotherapy, laser therapy in the same regimen as in group 1 supplemented after 2-3 hours by abdominal magnetic therapy. Group 3 (control) received traditional pharmacotherapy in the combination with antibacterial and anti-inflammatory medicines. It was demonstrated that the patients of group 2 exhibited the most pronounced positive dynamics of the clinical signs and symptoms estimated from the total National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and of the characteristics of the quality of life evaluated based on the QLS scale. The patients of the two former groups experienced a more conspicuous decrease in the activity of the inflammatory process in seminal vesicles, restoration of their structural and anatomical features (as shown by the transrectal ultrasound study), improvement of testosterone metabolism, and normalization of the spermogram characteristics in comparison with controls. The analysis of the spermograms revealed the tendency toward the increase in the number of actively motile spermatozoa

    Background The aim of this study was to undertake a histological evaluation of the presence of eosinophils in esophageal muscle in patients with achalasia before treatment with peroral endoscopic myotomy (POEM), with clinical follow-up at one year. Material/Methods Before treatment, esophageal biopsies including mucosa and esophageal muscle were obtained from 28 patients with achalasia. Nine patients who had undergone esophagectomy for esophageal carcinoma were included in the control group. The Eckardt Score was used to evaluate the clinical symptoms of achalasia. Histology of routinely processed tissue sections was used to perform eosinophil cell counts (0 to +++), and immunohistochemistry was used to detect expression of eosinophil major basic protein (MBP), eosinophil-derived neurotoxin (EDN), and S100 protein in cases of achalasia (n=28) and controls (n=9). The findings in patients with achalasia were compared before and one year following POEM. Results Esophageal tissue from patients with achalasia showed eosinophils infiltrating into the muscularis externa in 85.7% (24/28), into the muscularis propria in 28.6% (8/28), and in 89% (25/28) there were few remaining myenteric ganglion cells, before POEM. The extent of inflammation was similar in all regions of the esophagus and between subtypes of achalasia. At one year following POEM, the Eckardt Scores between the former eosinophil (0) group and the eosinophil (+++) group were significantly different (Z=3.50, P=0.030). Conclusions Achalasia of the esophagus was associated with infiltration of the esophageal muscle by activated eosinophils and a decrease in the density of ganglion cells in the myenteric esophageal plexus.

    Postpartum discharge instructions are a crucial part of a mother's birth experience. Finding the method to provide those discharge instructions in a manner that increases the mother's satisfaction with her hospital experience is important. This quasi-experimental study examined the relationship between new mothers' interaction with nurses providing postpartum instructions by the traditional and class methods and their satisfaction with discharge teaching. The results indicated new mothers were satisfied with both methods of discharge teaching; however, they were more likely to report stronger agreement with overall satisfaction with the traditional method of discharge teaching than with attending the discharge class.

    Full Text Available Background Visual acuity, like many other health-related problems, does not have an equal distribution in terms of socio-economic factors. We conducted this study to estimate and decompose economic inequality in presenting visual acuity using two methods and to compare their results in a population aged 40-64 years in Shahroud, Iran. Methods: The data of 5188 participants in the first phase of the Shahroud Cohort Eye Study, performed in 2009, were used for this study. Our outcome variable was presenting vision acuity (PVA that was measured using LogMAR (logarithm of the minimum angle of resolution. The living standard variable used for estimation of inequality was the economic status and was constructed by principal component analysis on home assets. Inequality indices were concentration index and the gap between low and high economic groups. We decomposed these indices by the concentration index and BlinderOaxaca decomposition approaches respectively and compared the results. Results The concentration index of PVA was -0.245 (95% CI: -0.278, -0.212. The PVA gap between groups with a high and low economic status was 0.0705 and was in favor of the high economic group. Education, economic status, and age were the most important contributors of inequality in both concentration index and Blinder-Oaxaca decomposition. Percent contribution of these three factors in the concentration index and Blinder-Oaxaca decomposition was 41.1% vs. 43.4%, 25.4% vs. 19.1% and 15.2% vs. 16.2%, respectively. Other factors including gender, marital status, employment status and diabetes had minor contributions. Conclusion This study showed that individuals with poorer visual acuity were more concentrated among people with a lower economic status. The main contributors of this inequality were similar in concentration index and Blinder-Oaxaca decomposition. So, it can be concluded that setting appropriate interventions to promote the literacy and income level in people

    Hemophagocytic lymphohistiocytosis (HLH) is an often-fatal hyperinflammatory syndrome characterized by fever, hepatosplenomegaly, cytopenia, and in some cases hemophagocytosis. Here, we describe the mutation analysis, clinical presentation, and functional analysis of natural killer (NK) cells...... (FHL), the clinical findings included colitis, bleeding disorders, and hypogammaglobulinemia in approximately one-third of the patients. Laboratory analysis revealed impairment of NK-cell degranulation and cytotoxic capacity. Interleukin-2 stimulation of lymphocytes in vitro rescued the NK cell......-associated functional defects. In conclusion, familial HLH type 5 is associated with a spectrum of clinical symptoms, which may be a reflection of impaired expression and function of Munc18-2 also in cells other than cytotoxic lymphocytes. Mutations in STXBP2 should thus also be considered in patients with clinical...

    Objective: To detect the differences of grey matter volume between the patients with mental retardation (MR) presented clinically as operation deficit (OD) or as language deficit (LD) and the children with typical normal development using optimal VBM. The developmental connections between brain gray matter and language or operation skills were examined. Methods: Magnetic resonance imaging was obtained from 9 children with mental retardation presented as OD predominantly and 11 children with mental retardation presented as LD mainly, as well as the age-matched control group (11 and 14 normal children,respectively) on a 1.5 T scanner. Voxel-based morphometry analysis with an optimization of spatial segmentation and normalization procedures was applied to compare the volume of grey matter between the two groups (OD VS.control; LD VS.control). Statistically, the total and local gray matter volumes were compared between the two groups with t test. Results: The total gray matter volume of OD group was [(1.030 ± 0.078) × 10 6 mm 3 ]. Compared to that of controls [(0.984 ± 0.058) × 10 6 mm 3 ], it was increased significantly (t=-2.6, P<0.05). And the gray matter volume in the posterior cingulated gyrus, left superior prefrontal gyrus, left cuneus, left middle prefrontal gyrus and the body of left caudate nucleus showed significantly increased. Meanwhile, the total gray matter volume of the MR children presented as LD [(1.002 ± 0.068) × 10 6 mm 3 ] showed significantly increased(t=-3.0, P<0.05) compared with that of control group [(0.957 ±0.057) × 10 6 mm 3 ]. The gray matter volume in bilateral thalami, the left inferior temporal gyrus,the left inferior frontal gyrus, and the left cerebellum of the LD group was more than that of normal children. Conclusion: As revealed by VBM, there are differences in alterations of gray matter volume between MR children presented with OD and with LD relative to control. (authors)

    Full Text Available Foreign body ingestion occurs in not only children but also adults, particularly those with history of neurologic disease, alcohol use, or psychiatric disease. We present the case of a 40-year-old male with schizophrenia who presented to the emergency room with a long history of pharyngeal foreign body sensation which had recently progressed to include trismus, odynophagia, and dyspnea. Flexible laryngoscopy demonstrated fullness of the right posterior pharyngeal wall and computed tomography (CT showed a linear opaque foreign body extending from the level of the oropharynx to the thyroid ala. Further history elicited that he stabbed himself in the pharynx two years prior with a toothbrush following a command hallucination. The toothbrush was removed uneventfully via an external approach. The patient was discharged with psychiatry follow-up. This case is unusual due to the submucosal location of the foreign body and the length of retention. It demonstrates the atypical nature which patients with comorbid psychiatric illness may present following foreign body injury and the use of an external surgical approach for the removal of a retained foreign body based on CT reconstruction.

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

    Introduction. Spontaneous Escherichia coli meningitis is an infrequent condition in adults and is associated with some predisposing factors, including severe Strongyloides stercoralis (SS) infections. Case Presentation. A 43-year-old Hispanic man, with history of travelling to the jungle regions of Peru and Brazil two decades ago, and who received prednisone due to Bell's palsy for three weeks before admission, presented to the Emergency Department with diarrhea, fever, and hematochezia. A week after admission he developed drowsiness, meningeal signs, abdominal distension, and constipation. A cerebrospinal fluid culture showed extended spectrum β -lactamase producing E. coli. A colonoscopy was performed and showed pancolitis. Three days after the procedure the patient became unstable and developed peritoneal signs. He underwent a laparotomy, which ended up in a total colectomy and partial proctectomy due to toxic megacolon. Three days later the patient died in the intensive care unit due to septic shock. Autopsy was performed and microscopic examination revealed the presence of multiple Strongyloides larvae throughout the body. Conclusion. Strongyloides stercoralis infection should be excluded in adults with spontaneous E. coli meningitis, especially, if gastrointestinal symptoms and history of travelling to an endemic area are present. Even with a proper diagnosis and management, disseminated strongyloidiasis has a poor prognosis.

    Compulsive buying is defined as repetitive impulsive and excessive buying leading to personal and familial distress. This study compares the buying behavior of depressed patients presenting with or without compulsive buying. The weight of promotional factors such as sales and advertising campaigns was systematically assessed. The impulsive nature of compulsive buying and the choice of items purchased were also investigated. For this purpose, we studied buying behavior among 52 inpatients diagnosed for major depressive episode with DSM-IV criteria. None of the patients presented mania or hypomania, obsessive-compulsive disorder, or alcohol or drug abuse or dependence disorder. We assessed the prevalence of compulsive buying and compared the "buying style" among patients with (CB+) and without (CB-) compulsive buying. The diagnosis of depression was assessed with the Mini International Neuropsychiatric Interview (MINI). The diagnosis of compulsive buying was made using standardized criteria and a specific rating scale. All patients answered a specific questionnaire assessing the phenomenology of the buying behavior. Twenty-one of 52 depressives presented with compulsive buying. The CB+ group was not more sensitive to promotional factors. They did not seek sales or use loans significantly more than others. Upon entering a shop, the CB+ subjects did not change their choice more often than others. CB+ subjects were significantly more often alone while shopping (85% of cases v61% of CB- group, p = .05). Most purchases from the CB+ group were self-gifts or gifts to others (50.4% v 23.5%, p = .003); 14.4% of purchases in the CB+ group (v 2.2% in CB- group, P = .045) were made because the patients believed their social status requires acquisition. Items to be bought were more often considered by CB+ subjects as occasions not to be missed (31.4% v15.1%, P = .03). Purchases were significantly (57% v 16%) less often used than expected by the CB+ group (P = .002). Most

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

    There are limited data on which patients not treated with intravenous (IV) tissue-type plasminogen activator (tPA) due to mild and rapidly improving stroke symptoms (MaRISS) have unfavorable outcomes. Acute ischemic stroke (AIS) patients not treated with IV tPA due to MaRISS from January 1, 2009 to December 31, 2013 were identified as part of the Georgia Coverdell Acute Stroke Registry. Multivariable regression analysis was used to identify factors associated with a lower likelihood of favorable outcome, defined as discharge to home. There were 1614 AIS patients who did not receive IV tPA due to MaRISS (median National Institutes of Health stroke scale [NIHSS] 1], of which 305 (19%) did not have a favorable outcome. Factors associated with lower likelihood of favorable outcome included Medicare insurance status (odds ratio [OR]: .53, 95% confidence interval [CI]: .34-.84), arrival by emergency medical services (OR: .46, 95% CI: .29-.73), increasing NIHSS score (per unit OR: .89, 95% CI: .84-.93), weakness as the presenting symptom (OR: .50, 95% CI: .30-.84), and a failed dysphagia screen (OR: .43, 95% CI: .23-.80). During the study period, dysphagia screen identify a subgroup of patients who are more likely to have an unfavorable outcome. Whether IV tPA treatment can improve the outcome in this subgroup of patients needs to be evaluated in a randomized placebo-controlled trial. Copyright © 2016 National Stroke Association.

    Some patients who present with an acute feeling of imbalance are experiencing an ischemic stroke that is not evident on computed tomography (CT) scans. The aim of this study was to compare ischemic stroke and nonischemic vertigo patient groups and to investigate independent factors associated with ischemic stroke. We examined 332 consecutive patients with an acute feeling of imbalance who showed no neurologic findings or responsible lesions on CT scan at the hyperacute phase. We examined their clinical backgrounds, physical findings, and laboratory examinations, with ischemic stroke diagnosed by later CT and/or magnetic resonance imaging (MRI). We identified 41 (12.3%) ischemic stroke patients. Atrial fibrillation (odds ratio 4.1; 95% confidence interval 1.4-11.5), white blood cell count (10(3)/μL, 1.4; 1.2-1.6), head and/or neck pain (4.6; 2.1-10.3), first attack of imbalance feeling (3.3; 1.1-12.2), and dizziness (3.7; 1.7-8.3) were significant and independent factors associated with ischemic stroke among patients with an acute feeling of imbalance. We used these factors to calculate an "imbalance score"; 1 point was given for the presence of each factor and a score of 3-5 points was independently associated with ischemic stroke. An awareness of these factors may indicate that further examinations including MRI are necessary to rule out ischemic stroke. Copyright © 2014 National Stroke Association. Published by Elsevier Inc.

    To evaluate the value of ultrasonographic features of crystal deposition for diagnosing gout in patients presenting with acute arthritis. Ultrasound scanning of the most inflamed joint was performed on 89 consecutively enrolled patients with acute arthritis. Two radiologists independently reviewed the ultrasound images, and a consensus was achieved with a third radiologist when the interpretations of four key ultrasound features of gout differed. Arthrocentesis and crystal analysis using compensated polarized light microscopy of aspirates are considered the gold standards for gout diagnosis. Fifty-three (60%) patients had gout, whereas the remaining 36 (40%) had non-gout arthritis. The mean serum uric acid level was 7.1 mg/dl in patients with gout and 4.7 mg/dl in patients with non-gout arthritis. Three US features differed significantly (p non-gout arthritis: the double contour sign (42 vs. 8%, respectively), intra-articular aggregates (58 vs. 8%), and tophi (40 vs. 0%). No statistically significant differences in detecting intra-tendinous aggregates (32 vs. 17%, p = 0.14) were observed. The sensitivity and specificity of the double contour sign were 42 and 92%, respectively; those of the intra-articular aggregates were 58 and 92%; and those of tophi were 40 and 100%. The positive predictive values for these three features ranged from 88 to 100%, whereas the negative predictive values ranged from 52 to 60%. When the prevalence is high, these three ultrasound features may be a useful adjunct in the diagnosis of acute gout, particularly when specialized microscopic techniques are not available.

    In elastography, quantitative elastograms are desirable as they are system and operator independent. Such quantification also facilitates more accurate diagnosis, longitudinal studies and studies performed across multiple sites. In optical elastography (compression, surface-wave or shear-wave), quantitative elastograms are typically obtained by assuming some form of homogeneity. This simplifies data processing at the expense of smearing sharp transitions in elastic properties, and/or introducing artifacts in these regions. Recently, we proposed an inverse problem-based approach to compression OCE that does not assume homogeneity, and overcomes the drawbacks described above. In this approach, the difference between the measured and predicted displacement field is minimized by seeking the optimal distribution of elastic parameters. The predicted displacements and recovered elastic parameters together satisfy the constraint of the equations of equilibrium. This approach, which has been applied in two spatial dimensions assuming plane strain, has yielded accurate material property distributions. Here, we describe the extension of the inverse problem approach to three dimensions. In addition to the advantage of visualizing elastic properties in three dimensions, this extension eliminates the plane strain assumption and is therefore closer to the true physical state. It does, however, incur greater computational costs. We address this challenge through a modified adjoint problem, spatially adaptive grid resolution, and three-dimensional decomposition techniques. Through these techniques the inverse problem is solved on a typical desktop machine within a wall clock time of 20 hours. We present the details of the method and quantitative elasticity images of phantoms and tissue samples.

    We report a surgical case of tension pyopneumothorax in a patient who was receiving chemotherapy for esophageal cancer. A 68-year-old man who had undergone total gastrectomy with splenectomy for gastric cancer and was receiving chemotherapy for esophageal cancer was presented to our hospital with dyspnea. Left tension pyopneumothorax was diagnosed, and he received left lower lobectomy after pleural drainage. His postoperative course was uneventful, and he is alive without any cancer recurrences 5 years after the lobectomy. Once tension pyopneumothorax has developed from lung abscess, emergent lobectomy may be a useful option to prevent lethal aspiration pneumonia.

    We describe herein a woman who developed subcutaneous gummas in her trochanteric regions, bilaterally, although she had been treated for syphilis two decades earlier. Evidence of Treponema pallidum latent late infection was the presence of IgG antibodies against T. pallidum and the positive non-treponemal and treponemal tests. Moreover, immunohistochemical staining for T. pallidum detected some spirochetes close to the atrophic adipocytes allowing the diagnosis of lypo-atrophic panniculitis tertiary syphilis. This is the first case of tertiary syphilis presenting as panniculitis in an immunocompetent patient, demonstrating that subcutaneous fat may be another organ infected in tertiary syphilis.

    Castleman disease (CD) is a rare poorly understood lymphoproliferative disorder. Pediatric onset CD has been reported before. However, most of them have benign unicentric pattern. Multicentric CD (MCD) is quite rare in children. Herein, we report a 13-year-old adolescent boy with MCD of the hyaline vascular variant presenting with pleural and pericardial effusion, which is an uncommon presentation. MCD should be considered in the differential diagnosis of pleural and/or pericardial effusion with unexplained lymph nodes in children. What is Known •Pediatric Castleman disease (CD) most commonly occurs in the unicentric form, which typically is asymptomatic and cured by lymph node excision. •The diagnosis of MCD can be difficult owing to the heterogeneity of presentation and potential for nonspecific multisystem involvement. What is New •A 13-year-old adolescent boy was diagnosed with MCD of the hyaline vascular variant presenting with pleural and pericardial effusion, which is an uncommon presentation. •In a pediatric patient with fever, pleural-pericardial effusion and multiple lymph nodes, MCD should be considered in differantial diagnosis.

    Full Text Available Impairments of speech and language are important consequences of head injury as they compromise interaction between the patient and others. A large spectrum of communication deficits can occur. There are few reports in the literature of aphasia following closed head injury despite the common presentation of closed head injury. Herein we report two cases of closed head injuries with differing forms of aphasia. We discuss their management and rehabilitation and present a detailed literature review on the topic. In a busy acute surgical unit one can dismiss aphasia following head injury as behaviour related to intoxication. Early recognition with prolonged and intensive speech and language rehabilitation therapy yields a favourable outcome as highlighted in our experience. These may serve as a reference for clinicians faced with this unusual outcome.

    Impairments of speech and language are important consequences of head injury as they compromise interaction between the patient and others. A large spectrum of communication deficits can occur. There are few reports in the literature of aphasia following closed head injury despite the common presentation of closed head injury. Herein we report two cases of closed head injuries with differing forms of aphasia. We discuss their management and rehabilitation and present a detailed literature review on the topic. In a busy acute surgical unit one can dismiss aphasia following head injury as behaviour related to intoxication. Early recognition with prolonged and intensive speech and language rehabilitation therapy yields a favourable outcome as highlighted in our experience. These may serve as a reference for clinicians faced with this unusual outcome.

    Wilson's disease typically presents symptoms associated with liver damage or neuropsychiatric disturbances, while endocrinologic abnormalities are rare. We report an unprecedented case of hypopituitarism in a patient with Wilson's disease. A 40-year-old woman presented with depression, general weakness and anorexia. Laboratory tests and imaging studies were compatible with liver cirrhosis due to Wilson's disease. Basal hormone levels and pituitary function tests indicated secondary hypothyroidism and adrenal insufficiency due to hypopituitarism. Brain MRI showed T2 hyperintense signals in both basal ganglia and midbrain but the pituitary imaging was normal. She is currently receiving chelation therapy along with thyroid hormone and steroid replacement. There may be a relationship between Wilson's disease and hypopituitarism. Copper deposition or secondary neuronal damage in the pituitary may be a possible explanation for this theory.

    Posterior reversible encephalopathy syndrome (PRES) is an uncommon but well-known complication after transplantation diagnosed by characteristic radiological features. As limited data on this complex syndrome exist we sought to better define the incidence, clinical presentation and risk factors for PRES in liver transplant (LTx) patients. We conducted a retrospective analysis of 1923 adult LTx recipients transplanted between 2000 and 2010. PRES was diagnosed radiologically in 19 patients (1%), with 84% of cases occurring within 3 months post-LTX. We compared this cohort of PRES patients to 316 other LTx recipients also requiring radiographic imaging within 3 months after LTx for neurological symptoms. Seizure was the most common clinical manifestation in the PRES group (88% vs. 16%, pliver disease and infection/sepsis. These factors may be related to a common pathway of vascular dysregulation/damage that appears to characterize this complex syndrome. Intracranial bleeding and seizures may be the end result of these phenomena. The relationship of these associated factors to the hypothesized pathophysiology of PRES is discussed. © Copyright 2012 The American Society of Transplantation and the American Society of Transplant Surgeons.

    The Stewart-Treves syndrome with localisation in the region of the lower extremities is not something unusual as clinical pathology, but the clinical diagnostics is rather difficult, and it can be further complicated maximally because of: the similar locoregional findings in patients with other cutaneous malignancies. Presented is a rare form of an epithelioid variant of the Stewart Treves syndrome in a woman, aged 81, localised in the region of the lower leg and significantly advanced only for 2 months. The diagnosis was confirmed histologically and immunohistochemically. Amputation of the affected extremity was planned. Discussed are important etiopathogenetic aspects regarding the approach in patients with lymphedema and possibility for development of the Stewart Treves syndrome. Analyzing the evidence from the literature worldwide, we concluded that perhaps the only reliable (to some extent) therapeutic option in patients with Stewart Treves Syndrome is 1) the early diagnostics and 2) the following inevitable radical excision or amputation with the maximal field of surgical security in the proximal direction.

  19. A patient with metastatic melanoma presenting with gastrointestinal perforation after dacarbazine infusion: a case report

    Full Text Available Abstract Introduction We report a rare case of gastrointestinal perforation following dacarbazine infusion for metastatic melanoma. The condition is attributed to a responding malignant melanoma in the gastrointestinal tract. Case presentation A 52-year-old Caucasian man presented with abdominal pain and distension, malaise, night sweats, dysphagia and early satiety. A computed tomography scan showed massive ascites, lymphadenopathy and liver lesions suspect for metastases. An upper gastrointestinal endoscopy was performed and revealed multiple dark lesions of 5 mm to 10 mm in his stomach and duodenum. When his skin was re-examined, an irregular pigmented lesion over the left clavicle measuring 15 mm × 8 mm with partial depigmentation was found. Histological examination of a duodenal lesion was consistent with a diagnosis of metastatic melanoma. The patient deteriorated and his level of lactate dehydrogenase rapidly increased. The patient was started on systemic treatment with dacarbazine 800 mg/m2 every three weeks and he was discharged one day after the first dose. On the sixth day he was readmitted with severe abdominal pain. A chest X-ray showed the presence of free intraperitoneal air that was consistent with gastrointestinal perforation. His lactate dehydrogenase level had fallen from 6969U/L to 1827U/L, supporting the conclusion that the response of gastrointestinal metastases to dacarbazine had resulted in the perforation of the patient's bowel wall. A laparotomy was discussed with the patient and his family but he decided to go home with symptomatic treatment. He died 11 days later. Conclusion Melanoma can originate in, as well as metastasize to, the gastrointestinal tract. Gastrointestinal perforations due to responding tumors are a well-known complication of systemic treatment of gastrointestinal lymphomas. However, as the response rate of metastatic melanoma to dacarbazine is only 10% to 20%, and responses are usually only partial

    Visual acuity, like many other health-related problems, does not have an equal distribution in terms of socio-economic factors. We conducted this study to estimate and decompose economic inequality in presenting visual acuity using two methods and to compare their results in a population aged 40-64 years in Shahroud, Iran. The data of 5188 participants in the first phase of the Shahroud Cohort Eye Study, performed in 2009, were used for this study. Our outcome variable was presenting vision acuity (PVA) that was measured using LogMAR (logarithm of the minimum angle of resolution). The living standard variable used for estimation of inequality was the economic status and was constructed by principal component analysis on home assets. Inequality indices were concentration index and the gap between low and high economic groups. We decomposed these indices by the concentration index and BlinderOaxaca decomposition approaches respectively and compared the results. The concentration index of PVA was -0.245 (95% CI: -0.278, -0.212). The PVA gap between groups with a high and low economic status was 0.0705 and was in favor of the high economic group. Education, economic status, and age were the most important contributors of inequality in both concentration index and Blinder-Oaxaca decomposition. Percent contribution of these three factors in the concentration index and Blinder-Oaxaca decomposition was 41.1% vs. 43.4%, 25.4% vs. 19.1% and 15.2% vs. 16.2%, respectively. Other factors including gender, marital status, employment status and diabetes had minor contributions. This study showed that individuals with poorer visual acuity were more concentrated among people with a lower economic status. The main contributors of this inequality were similar in concentration index and Blinder-Oaxaca decomposition. So, it can be concluded that setting appropriate interventions to promote the literacy and income level in people with low economic status, formulating policies to address

    Aim: To identify predictors of acute ischaemic stroke (AIS) and evaluate the diagnostic yield and impact of magnetic resonance imaging (MRI) in patients imaged for dizziness and vertigo. Materials and methods: Patients imaged using MRI, including diffusion-weighted imaging (DWI) with or without computed tomography (CT), for dizziness and vertigo over a 2-year period were identified retrospectively. MRI findings were categorised as “acute ischaemic stroke”, “significant”, or “non-significant”. We reviewed the medical records to identify presenting symptoms and signs, vascular risk factors, duration of symptoms, and pre- and post-MRI clinical management in patients with proven stroke. Results: One hundred and eighty-eight patients were included: 39 with vertebrobasilar AIS (20.7%), 32 (17%) with a significant but non-ischaemic abnormality, and 117 (62.2%) with a normal or non-related abnormality. The sensitivity of CT in diagnosing AIS was 9.52% (95% CI: 1.67–31.8%). Posterior inferior cerebellar artery (PICA) territory infarcts were the most common (38.5%). Patients with AIS were significantly more likely to be older than 50 years (p = 0.04), have a greater number of cardiovascular risk factors (p < 0.01), shorter duration of symptoms (p = 0.03), and at least one neurological sign (p = 0.02). DWI MRI had a diagnostic impact on 21.6% patients with stroke. Conclusion: MRI plays an important role in differentiating peripheral and central aetiology when this proves challenging clinically. Predictors of AIS were identified that aid patient selection for MRI, to increase the yield and impact of neuroimaging. -- Highlights: •CT has a low sensitivity for diagnosing stroke in patients with dizziness and vertigo. •The yield of MRI for stroke in patients with these symptoms in our study was 21%. •The diagnostic impact of MRI on the management of these patients was 22%. •Predictors of stroke to increase the yield of MRI in this clinical context are

    Full Text Available Adult onset Still’s disease (AOSD is a rare inflammatory disorder of unknown etiology that usually affects young adults. Very few patients older than 70-year-old have been reported. Clinical features include quotidian fevers, arthralgias, arthritis, pharyngitis, lymphadenopathy and an evanescent rash. AOSD should be considered in the differential diagnosis of fever of unknown origin. Early diagnosis is often difficult since it is a diagnosis of exclusion and the presence of infectious, neoplastic and autoimmune conditions needs to be ruled out before the diagnosis is made. No specific laboratory tests are available to aid in the diagnosis of AOSD. As a result, a set of diagnostic criteria that define the clinical features of this condition, termed the Yamaguchi criteria, have been most commonly used to establish the diagnosis. We describe the case of a 72-year-old Caucasian male with past medical history significant for generalized anxiety disorder, depression, BPH, and hypertriglyceridemia, who presented to a tertiary institution complaining of profound generalized weakness and weight loss that started three weeks prior to presentation. Initial laboratory studies showed leukocytosis, elevated ESR, CRP, ferritin and liver dysfunction. Cultures, ANA and rheumatoid factor studies were negative. The patient underwent further extensive workup that excluded the presence of infectious, neoplastic and autoimmune disorders and was subsequently diagnosed with AOSD and new onset diabetes mellitus. For the management of AOSD he was started on prednisone with significant improvement in markers of inflammation, symptoms and level of function.

    A qualitative study was undertaken with men treated for testicular tumours, to ascertain how they interpreted their symptoms and the factors which influenced a decision to consult a physician. The research was undertaken with six men who had been diagnosed as having testicular tumours. Interviews were also conducted with four wives and one mother. The findings showed that giving men information on testicular cancer may not guarantee early presentation. Symptoms were not generally attributed to cancer and the one patient who practised self-examination had delayed seeking help for 6 months. The extent to which symptoms affected the patient's lifestyle was also a factor in the decision-making process, as was the checking of symptoms with other family members. Wives were often pivotal in persuading men to seek help. The discovery of testicular symptoms produced emotional responses which included embarrassment and fear of both cancer and castration. There was evidence of strong feelings of masculine identity bound up with the appearance of 'normal' genitals. Provider-delay was identified in four cases and was associated with misattribution of symptoms by physicians and the failure to initiate specialist referral. Delay was under-recorded in the hospital notes in all cases where presentation was not immediate.

    Full Text Available In clinical practice the term “megacolon” is used to indicate a marked dilatation of the cecum and the sigmoid colon (>12 and 6.5 cm, respectively (1. From a clinical standpoint, a megacolon can be classified as chronic or acute depending on its clinical presentation. Chronic megacolon typically refers to a congenital disorder in which the enteric nervous system (ENS supplying the colon does not develop properly, thereby leaving the distal segments of the viscus without myenteric and submucosal ganglia (i.e. Hirschsprung’s disease (2. Other cases of non-aganglionic chronic megacolon can be secondary to variety of conditions such as Chagas’ disease and neurodegenerative diseases (e.g. Parkinson’s and Alzheimer’s diseases, leading to or associated with ENS abnormalities (3. The acute form of megacolon, also referred to as Ogilvie’s syndrome, is characterized by a predominant involvement of the cecum and right colon usually affecting elderly patients undergoing surgery (e.g. orthopedic procedures or taking medications altering gut motility (e.g. opioids or antidepressants (4. Some forms of acute megacolon, however, can be idiopathic in origin since no underlying etiology can be identified. Patients with acute idiopathic megacolon usually have a longstanding history of constipation, often accompanied by laxative abuse, and their clinical presentation is characterized by abdominal distension and severe pain with radiological evidence of stool impacted in the colon and rectum (1, 4. The case herein reported represents an unusual form of acute idiopathic megacolon characterized by massive descending and sigmoid colon distension complicated with a volvulus in a 14-year-old boy with no Hirschsprung’s disease. In addition, just to increase the peculiarity of this case report, the patient had an unremarkable clinical record, and never suffered from chronic constipation in the past.

  5. Male patients presenting with rapidly progressive puberty associated with malignant tumors

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

    Full Text Available Somatically acquired genomic alterations with MYCN amplification (MNA are key features of neuroblastoma (NB, the most common extra-cranial malignant tumour of childhood. Little is known about the frequency, clinical characteristics and outcome of NBs harbouring genomic amplification(s distinct from MYCN.Genomic profiles of 1100 NBs from French centres studied by array-CGH were re-examined specifically to identify regional amplifications. Patients were included if amplifications distinct from the MYCN locus were seen. A subset of NBs treated at Institut Curie and harbouring MNA as determined by array-CGH without other amplification was also studied. Clinical and histology data were retrospectively collected.In total, 56 patients were included and categorised into 3 groups. Group 1 (n = 8 presented regional amplification(s without MNA. Locus 12q13-14 was a recurrent amplified region (4/8 cases. This group was heterogeneous in terms of INSS stages, primary localisations and histology, with atypical clinical features. Group 2 (n = 26 had MNA as well as other regional amplifications. These patients shared clinical features of those of a group of NBs MYCN amplified (Group 3, n = 22. Overall survival for group 1 was better than that of groups 2 and 3 (5 year OS: 87.5%±11% vs 34.9%±7%, log-rank p<0.05.NBs harbouring regional amplification(s without MNA are rare and seem to show atypical features in clinical presentation and genomic profile. Further high resolution genetic explorations are justified in this heterogeneous group, especially when considering these alterations as predictive markers for targeted therapy.

    Peroxynitrite (ONOO(-)), formed by the reaction between nitric oxide (NO) and superoxide (O2(-)), has been implicated in the etiology of numerous disease processes. Peroxynitrite interacts with DNA via direct oxidative reactions or via indirect radical-mediated mechanism. It can inflict both oxidative and nitrosative damages on DNA bases, generating abasic sites, resulting in the single strand breaks. Plasmid pUC 18 isolated from Escherichiacoli was modified with peroxynitrite, generated by quenched flow process. Modifications incurred in plasmid DNA were characterized by ultraviolet and fluorescence spectroscopy, circular dichroism, HPLC and melting temperature studies. Binding characteristics and specificity of antibodies from diabetes patients were analyzed by direct binding and inhibition ELISA. Peroxynitrite modification of pUC 18 plasmid resulted in the formation of strand breaks and base modification. The major compound formed when peroxynitrite reacted with DNA was 8-nitroguanine, a specific marker for peroxynitrite induced DNA damage in inflamed tissues. The concentration of 8-nitroguanine was found to be 3.8 μM. Sera from diabetes type 1 patients from different age groups were studied for their binding to native and peroxynitrite modified plasmid. Direct binding and competitive-inhibition ELISA results showed higher recognition of peroxynitrite modified plasmid, as compared to the native form, by auto-antibodies present in diabetes patients. The preferential recognition of modified plasmid by diabetes autoantibodies was further reiterated by gel shift assay. Experimentally induced anti-peroxynitrite-modified plasmid IgG was used as a probe to detect nitrosative lesions in the DNA isolated from diabetes patients. Copyright © 2014 Elsevier Inc.

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

    Full Text Available Background: Need for undertaking prostate biopsies for detection of prostate cancer is often decided on the basis of serum levels of prostate specific antigen (PSA. Aim: To evaluate the case detection rate of prostate cancer among patients presenting with lower urinary tract symptoms (LUTS on the basis of PSA levels and to assess the scope of prostate biopsy in these patients. Setting and Design: A retrospective study from a tertiary care center. Materials and Methods: The clinical and histopathological data of 922 patients presenting with LUTS in the last five years was obtained from the medical record section. They had been screened for prostate cancer using PSA and /or digital rectal examination examination followed by confirmation with prostate biopsy. Statistical Analysis Used: Detection rate and receiver operating characteristic curve were performed using SPSS 16 and Medcalc softwares. Results: The detection rate of prostate cancer according to the PSA levels was 0.6%, 2.3%, 2.5%, 34.1% and 54.9% in the PSA range of 0-4, 4-10, 10-20, 20-50 and> 50 ng/ml, respectively. Maximum prostate cancer cases were detected beyond a PSA value of 20 ng/ml whereas no significant difference in the detection rate was observed in the PSA range of 0-4, 4-10 and 10-20 ng/ml. Conclusion: A low detection rate of prostate cancer observed in the PSA range of 4-20 ng/ml in LUTS patients indicates the need for use of higher cutoff values of PSA in such cases. Therefore we recommend a cutoff of 20 ng/ml of PSA for evaluation of detection rate of prostate cancer among patients presenting with LUTS.

    This paper was designed to discuss the problems of co-morbidity and approaches to the rehabilitation of the patients presenting with gastroesophageal reflux disease and a concomitant pathology and to analyze the issues concerning the possible vertebro-visceral correlations inherent in the diseases of the internal organs. To evaluate the vertebro-neurological status of the thoracic segment of the vertebral column in the patients suffering from gastroesophageal reflux disease and to further improve the methods for their treatment taking into consideration the concomitant pathology, if any. A total of 290 patients at the age varying from 25 to 60 (mean 44,3±11,3) years with the non-erosive form of gastroesophageal reflux disease were examined in the phase of its exacerbation. They included 132 (45.5%) men and 158 (54.5%) women. The duration of the disease averaged 13.1±3.3 years and that of the exacerbation period 1.2±0.5 months. All the patients underwent the vertebro-neurological examination. The visual analog scale was used to obtain the subjective characteristics of the pain syndrome associated with thoracalgia The quality of life of the patients was estimated based on the Medical Outcomes Study Short Form-36 (scores of MOS SF-36). To evaluate the effectiveness of the proposed approach to the treatment of the gastroesophageal reflux disease, the 260 participants of the study were randomly allocated to two groups, the main and control ones. The latter group was comprised of 130 patients given the standard treatment including the use of histamine H2-receptor antagonists, proton pump inhibitors, stimulators of the motility of the gastrointestinal tract, alginates, and other drugs, as indicated. The former group consisted of the remaining 130 patients undergoing the standard course of pharmacopuncture to correct the functional disorders in the thoracic segment of the vertebral column. The medications of choice for the purpose were the anti-homotoxic agents, such as

    Full Text Available The progress of epilepsies diagnosis has been great, but, amongst the diagnostic detailing that demand research, one of the most important is the essential lateralization and localization of epileptogenic zone, considered as the cerebral cortex region, that removed, will result in a free state of seizures. The present study aims to analyze the possible uses of proton spectroscopy for clinical and pre-surgical evaluation of focal extratemporal epilepsies, since this group presents the highest difficulty degree for lateralizing and locating epileptogenic zones. In almost all cases, a non invasive diagnosis can be performed using routine electroencephalography, video-electroencephalography - considered as gold standard, and magnetic resonance imaging. However, when the results of these exams are contradictory, some patients need invasive techniques, as the intra-cranial video-EEG, using deep electrodes, sub-dural strip and grid, that are associated with increased diagnostic cost and risk of complications, as cerebral hemorrhages and intra-cranial infections. Proton spectroscopy appears as a possibility, given its capacity to evaluate cerebral metabolism, by N-acetyl-aspartate (NAA, creatine (Cre and choline (Cho concentrations, amongst other metabolites. This non invasive method may provide time reduction of this evaluation and reliable level improvement for this topographical diagnosis.Tem sido grande o progresso no diagnóstico das epilepsias, mas dentre os detalhamentos diagnósticos a exigir pesquisas, estão a lateralização e a localização precisas da zona epileptogênica, considerada como a região do córtex cerebral que, removida, irá resultar num estado livre de crises. Por meio de revisão da literatura, o objetivo deste estudo é expor e analisar os métodos diagnósticos das epilepsias neocorticais extratemporais, dadas as características que as tornam mais complexas do que as epilepsias temporais visto que estas apresentam o

    Lead is an important toxic metal found in industrial communities. Due to the industrialization in the recent decade in Thailand, lead intoxication as a toxicant-related disorder becomes a new public health problem. A retrospective study on clinical presentation of hospitalized patients with diagnosis of lead intoxication during year 1990-1999 in King Chulalongkorn Memorial hospital, the largest Thai Red Cross Society Hospital, was performed. All 14 cases diagnosed with lead intoxication were identified in our series. Average age of the subjects was 25.55 +/- 21.93 years old. Male predominance was detected in our series (male:female = 12:2). Two main groups of subjects as; (1) childhood aged below 10 years old (male:female = 4:2) and (2) adult aged between 24 and 60 years old (n = 8, all male), can be identified. For the first group, the clinical presentations were convulsion (n = 3), unexplained anemia (n = 1), attention deficit (n = 1) and asymptomatic (n = 1), respectively. All of the subjects in this group presented the history of living at the old battery plant area. Five of the six cases came from the same village. For the second group, the clinical presentations were unexplained abdominal pain (n = 5), chronic renal failure (n = 1), unexplained anemia (n = 1) and asymptomatic (n = 1), respectively. Most of the subjects (75%) in this group presented the history of working in the battery plant for more than 10 years. Another case presented the history of gunshot and residual bullet in the bone marrow. The other one left is an interesting case with the history of prolonged usage of ritual pill and holy paper incineration. Like other studies, battery plant had strong relation with the lead intoxication. Although the total identified cases are rather few, there may be more undetected asymptomatic lead intoxication cases in the community. Specific control of lead resulted from battery plant and monitoring of the workers as public health strategies are still

    The advantages and disadvantages recognized by the Advisory Group on Heating and injection for twelve plasma heating and injection methods currently under investigation in Europe are related. The heating and injection requirements of four reference reactor designs are previously defined. The problems which arise when one attempts to extrapolate existing work towards the reactor goal are emphasized. Two refuelling methods not directly linked with the heating problem are discussed. The experiments in operation or under construction in Europe in which each method is investigated are listed. Sixteen working papers which served as a basis for the Advisory Group discussion and which cover all the heating and injection methods examined are included

    Full Text Available Introduction: Troponin test is one of the methods for diagnosing acute coronary syndrome, but the overuse and misuse of this test has increased the costs imposed on the health system and the patients. Objective: The present study was conducted to investigate the veracity of troponin test requests for patients presenting to an emergency department with chest pain and examine the effectiveness of training emergency medicine assistants in reducing unnecessary and inappropriate requests in emergency departments. Methods: This clinical audit was conducted in the emergency department of Imam Hossein Hospital, Tehran, Iran, in 2014. Sampling was carried out using the census method and all the cases presenting to the emergency department for whom a troponin test was requested by the emergency medical assistants were included in the research. First, the veracity of the current troponin test requests was assessed; then, training was given to the personnel, and the veracity of the troponin test requests was once again verified after the training was completed. The rate of veracious troponin requests for the patients was measured based on two factors, including the interval between the patients’ admission and the troponin test request, and the interval between the onset of pain and the troponin test request. The veracity of the troponin test request was compared before and after training using the Phi test and Cramer’s V test in IBM SPSS-21. Results: This study examined a total of 500 patients (250 before training and 250 after, who had a mean age of 57.65±18.15 years, including 51.6% men. Significant differences were observed between the mean time of the patients’ admission and the overall and post-training troponin test results (P=0.000, and also between the mean time of the onset of pain and the overall and post-training troponin test results (P=0.000. The number of positive troponin test results did not differ significantly between the patients

    Objectives: Consumer Health Informatics (CHI) and the use of Patient-Generated Health Data (PGHD) are rapidly growing focus areas in healthcare. The objective of this paper is to briefly review the literature that has been published over the past few years and to provide a sense of where the field is going. Methods: We searched PubMed and the ACM Digital Library for articles published between 2014 and 2016 on the topics of CHI and PGHD. The results of the search were screened for relevance and categorized into a set of common themes. We discuss the major topics covered in these articles. Results: We retrieved 65 articles from our PubMed query and 32 articles from our ACM Digital Library query. After a review of titles, we were left with 47 articles to conduct our full article survey of the activities in CHI and PGHD. We have summarized these articles and placed them into major categories of activity. Within the domain of consumer health informatics, articles focused on mobile health and patient-generated health data comprise the majority of the articles published in recent years. Conclusions: Current evidence indicates that technological advancements and the widespread availability of affordable consumer-grade devices are fueling research into using PGHD for better care. As we observe a growing number of (pilot) developments using various mobile health technologies to collect PGHD, major gaps still exist in how to use the data by both patients and providers. Further research is needed to understand the impact of PGHD on clinical outcomes. Georg Thieme Verlag KG Stuttgart.

    Transient headache and neurological deficits with cerebrospinal fluid lymphocytic pleocytosis (Handl) syndrome is a rare condition of unknown origin that is characterized by episodes of severe headache, transient neurological deficits that recur over less than 3 months, and lymphocytic pleocytosis in CSF. We report the case of a 14 year-old girl who presented with headache and vomiting that lasted 4 days, later combined with a clinical presentation of confusion, with a decrease in the level of consciousness, aphasia, peripheral facial paralysis, ataxia and fever for 24 hours. CSF analysis showed pleocytosis (110 cells/ml) and proteinorrachia (87 mg/dl). Electroencephalogram in the acute time showed generalized slowing, and later a focal slowing in the left hemisphere. She suffered 7 episodes of migraine (severe headache and vomiting) in the following two months, remaining asymptomatic thereafter. This is the first pediatric case published in the literature that presents with an agitated and/or confused state. This condition must be considered in the differential diagnosis of patients with headache and acute altered level of consciousness, in order to avoid prolonged treatments or unnecessary invasive testing.

    Full Text Available Abstract Background The chronic use of antifungal agents in the treatment of fungal infection in general and oropharyngeal candidiasis mainly in AIDS patient’s leads to the selection of strain resistant to these therapies and a shift in the spectrum of Candida species. This study determines the species diversity and in vitro susceptibility of Candida isolates from late presenting AIDS patients in northwest Ethiopia. Methods Two hundred and twenty one HIV/AIDS patients were assessed with a standardized evaluation form at enrolment. Oral rinses were cultured on CHROMagar plates at 37°C for 48 hours and Candida species identification were made following standard microbiological techniques. In vitro drug susceptibility tests were made using broth microdilution method. Results The colonization rate of Candida species was found to be 82.3% (177/215. C. albicans was the predominant species isolated from 139 (81% patients but there was a diversity of other species. C. glabrata was the most frequent non-albicans species isolated in 22.5% (40/177 of the patients followed by C. tropicalis 14.1% (27/177, C. krusei 5.6% (10 and other unidentifiable Candida species 4% (7/177. Recurrent episodes of oropharyngeal candidiasis and previous exposure to antifungal drugs were found to be predisposing factors for colonization by non-albicans species. Irrespective of the Candida species identified 12.2% (11/90, 7.7% (7/90 and 4.7% (4 of the isolates were resistant to fluconazole, ketoconazole and itraconazole, respectively. In contrast, resistance to micafungin, amphotericin B and 5-Fluorocytosine was infrequent. Conclusion HIV/AIDS patients are orally colonized by single or multiple albicans and non- albicans Candida species that are frequently resistant to azoles and occasionally to amphotericin B, 5-Fluorocytosine and micafungin. These highlight the need for national surveillance for examining Candida epidemiology and resistance to antifungal drugs.

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

    Full Text Available We report the case of a 44 year-old female, who presented a long-lasting, clinically atypical, secondary syphilis ("malignant syphilis" in the right foot, which started six months before medical evaluation. The patient had a serological diagnosis of HTLV-I infection and syphilis two years before the onset of the skin lesions, following a blood donation. As she believed she was allergic to penicillin, she initially received sulfamethoxazole + trimethoprim, without any improvement of the clinical picture. After failure of this first treatment regimen, she was given penicillin, which promoted complete healing of the lesion. We found evidence that infection by HTLV-I is capable of modifying the clinical course of secondary syphilis.

    Abnormalities of chromosome 22q11, including deletions and translocations, have been described in association with different birth defects and malformations occurring in many combinations and degrees of severity. We describe the case of an 8 month-old infant with no dysmorphic signs who showed progressive postnatal growth failure and no chronic systemic diseases. We found a 22q11.2 microdeletion, inherited from the mother, suggesting the diagnosis of DiGeorge syndrome. The patient had an isolated growth hormone (GH) deficiency and a significant increase in linear growth during the first and the second year of GH therapy, and a recovery of weight was shown. Sometimes, in infants with growth failure a genetic analysis is strongly suggested, since chromosomal abnormalities may be present.

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

    Full Text Available The incidence of congenital heart disease is about one percent of all live births in the United States. Treatment is being performed at a younger age and these children are showing improved survival. It is not unusual for children with congenital heart disease to present for non-cardiac surgery. Their management depends on their age, type of lesion, extent of corrective procedure, the presence of complications and other congenital anomalies. Each patient needs a detailed pre-operative evaluation to understand the abnormal anatomy and physiology, and related anaesthetic implications. No anaesthetic agent is an absolute contraindication, although drugs beneficial for one lesion may be detrimental for another. Regional anaesthesia has also been safely used in children with congenital heart disease. However the anaesthesiologist must have a detailed understanding of the pathophysiology of the lesion and the pharmacology of drugs being used to be able to provide safe anaesthesia for children with congenital heart disease.

    A 61-yr-old woman presented with complaints of weakness and pain in her legs. A magnetic resonance imaging showed a 3 x 5.6 x 7.8 cm mass lesion destructing the T1 and T2 vertebral bodies and compressing the spinal cord. The mass was excised surgically. It was follicular carcinoma metastasis of the cervicodorsal region. Then, she underwent a total thyroidectomy. Pathological examination showed two different types of carcinomas in two different focuses; follicular carcinoma in the left lobe and follicular variant papillary carcinoma in the isthmic lobe. After the operation she was given 100 mCi 131I. This is the first report of a patient who had both metastatic follicular carcinoma and follicular variant papillary carcinoma together.

    Full Text Available Introduction. Uterine fibroid tumors (uterine leiomyomas are the most common benign uterine tumors. The incidence of uterine fibroid tumors increases in older women and may occur in more than 30% of women aged 40 to 60. Many uterine fibroid tumors are asymptomatic and are diagnosed incidentally. Case Presentation. A 44-year-old woman was admitted to our hospital with general weakness, dyspepsia, abdominal distension, and a palpable abdominal mass. An abdominal computed tomography scan showed a huge tumor mass in the abdomen which was compressing the intestine and urinary bladder. Gastroduodenal endoscopic and biopsy results showed a Borrmann type IV gastric adenocarcinoma. The patient was diagnosed with gastric cancer with disseminated peritoneal carcinomatosis. She underwent a hysterectomy with both salphingo-oophorectomy and bypass gastrojejunostomy. Simultaneous uterine fibroid tumor with other malignancies is generally observed without resection. But in this case, a surgical resection was required to resolve an intestinal obstruction and to exclude the possibility of a metastatic tumor. Conclusion. When a large pelvic or ovarian mass is detected in gastrointestinal malignancy patients, physicians try to exclude the presence of a Krukenberg tumor. If the tumors cause certain symptoms, surgical resection is recommended to resolve symptoms and to exclude a metastatic tumor.

    BACKGROUND: Lacrimo-auriculo-dento-digital (LADD) syndrome (OMIM #149730) is an autosomal-dominant congenital disorder that can be caused by heterozygous mutations in the tyrosine kinase domains of the genes encoding fibroblast growth factor receptors 2 (FGFR2) and 3 (FGFR3), and has been found in association with a mutation in the FGF10 gene, which encodes an Fgfr ligand. Clinical signs vary, but the condition is characterised by involvement of the lacrimal and salivary systems, cup-shaped ears, hearing loss and dental abnormalities. Additional features may include involvement of the hands and feet with other body systems particularly the kidneys. CASE REPORT: Previous literature on the subject has been reviewed and this case is the first presentation of LADD syndrome in the Republic of Ireland, as a sporadic case in a 12-year-old girl who exhibited a range of dental and digital anomalies. TREATMENT: Her general medical practitioner managed her medical care whilst her oral care necessitated a multidisciplinary approach involving restorative and orthodontic elements. FOLLOW-UP: The initial restorative phase of treatment has successfully improved the appearance of the patient\\'s anterior teeth using direct resin composite build-ups.

    A woman aged 61 years presented to the emergency room with a 1-week history of dyspnoea on exertion and dry cough. X-ray of the chest showed diffuse interstitial opacities and was started on antibiotics and furosemide, and despite these measures, patient's respiratory status worsened, prompting endotracheal intubation. CT of the chest showed diffuse bilateral ground glass opacities and underwent bronchoscope with trans-bronchial biopsy that showed chronic bronchitis. Pt was empirically started on intravenous steroids due to concerns for interstitial lung disease (ILD). Autoimmune work up was sent and underwent video-assisted thoracoscopic surgery-guided biopsy of the lung that showed non-specific interstitial pattern with fibrosis. The patient was diagnosed as having antisynthetase syndrome with pulmonary involvement (ILD) as the cause of her acute respiratory failure. Azathioprine was started as steroid-sparing agent and was weaned off the ventilator to a tracheostomy collar and discharged to long-term rehabilitation centre. 2016 BMJ Publishing Group Ltd.

    Stenotrophomas maltophilia is an opportunistic Gram-negative bacillus and an important cause of nosocomial infections, particularly in immunosuppressed individuals. Although infections with this organism are most often in the form of pneumonia, bacteremia and endocarditis, awareness of the impact of S. maltophilia skin infections has been increasing. Here we describe a case of S. maltophilia cellulitis in a 65-year-old man with severe neutropenia and purpuric skin lesions to highlight the critical histopathological findings and correlate them with the clinical manifestations of the skin infection with this organism. Because identification of S. maltophilia can be challenging and infections are difficult to manage, this case illustrates essential considerations regarding the multifaceted histopathological, dermatological, clinical and microbiological aspects of the diagnosis and treatment of S. maltophilia cellulitis in a severely immunocompromised patient. Cognizance of the increasing incidence of nosocomial infections with uncommon microorganisms such as S. maltophilia is necessary when presented with atypical cutaneous manifestations, particularly in immunocompromised patients. © 2016 John Wiley & Sons A/S.

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

    Nuclear shape defects are a distinguishing characteristic in laminopathies, cancers, and other pathologies. Correlating these defects to the symptoms, mechanisms, and progression of disease requires unbiased, quantitative, and high-throughput means of quantifying nuclear morphology. To accomplish this, we developed a method of automatically segmenting fluorescently stained nuclei in 2D microscopy images and then classifying them as normal or dysmorphic based on three geometric features of the nucleus using a package of Matlab codes. As a test case, cultured skin-fibroblast nuclei of individuals possessing LMNA splice-site mutation (c.357-2A>G), LMNA nonsense mutation (c.736 C>T, pQ246X) in exon 4, LMNA missense mutation (c.1003C>T, pR335W) in exon 6, Hutchinson-Gilford Progeria Syndrome, and no LMNA mutations were analyzed. For each cell type, the percentage of dysmorphic nuclei, and other morphological features such as average nuclear area and average eccentricity were obtained. Compared to blind observers, our procedure implemented in Matlab codes possessed similar accuracy to manual counting of dysmorphic nuclei while being significantly more consistent. The automatic quantification of nuclear defects revealed a correlation between in vitro results and age of patients for initial symptom onset. Our results demonstrate the method's utility in experimental studies of diseases affecting nuclear shape through automated, unbiased, and accurate identification of dysmorphic nuclei.

    The SPECT with 123 I - iodolisuride has been effectuated in two centers (Coimbra and Tours) using cameras of different types in 28 patients presenting a Parkinson's disease (group 1) and 17 patients presenting an extra-pyramidal syndrome by striatal affliction (group 2), equally shared out between the two centers. The scintigraphy acquisition started 1 hour after a slow i.v. injection of labelled iodolisuride (0.02 to 0.07 ng/Kg of weight) with an activity 1.7 to 2.8 MBq of iodine 123. No undesirable effect was detected. The images observed on the sections crossing the central gray nuclei (CGN) were classified into 3 types defined according to visualisation of the CGN and/or the hemispheric cortex: type 1 - visible CGN and cortex un-visible; type 2 - visible CGN and cortex visible; type 3 - CGN and cortex visible. The associations expected were: group 1 - type 1 or 3; group 2 - type 2 or 3. In each center, independently of the utilized gamma camera, the obtained scintigraphic images were of high quality and interpretable. In the group 1, 28/29 scintigraphic images were classified as type 1 or 3 and 1/29 image was classified as type 2 while in the group 2, 14/17 images were classified as type 2 or 3 and 3/17 images as type 1. Consequently, this study concluded that the SPECT with 123 I - iodolisuride is achievable with any conventional tomographic camera and permits the classification of the extra-pyramidal syndromes as a function of striatal dopaminergic receptor waiting

    Two useful methods for the exact volumetric measurement of the neurocranium are introduced. Using these methods in a transversal study, mean ratio and range for normal boys and girls from birth to six months can be defined. Longitudinal studies and comparative literature research confirm the accuracy of these standard values. The application to pathological cases shows that hypogenesis of the neurocranium can be recognized earlier and more accurately by measuring the volume than by measuring the circumference of the head. Both methods are easy to apply and can be expected of every child. However, method B (dipping in the neurocranium and measuring the displaced water on a scale) has proved to be more accurate, simpler and faster.

    Significance of FISH method for detection of clonal chromosome aberration was reviewed. A clonal chromosome aberration is derived from one abnormal cell clone and gives the influence on the frequency of the aberration. As well, the size and frequency of the aberration give an important information concerning lymphocyte kinetics. FISH method is meaningful for detection of the clonal aberration. Fifteen kinds of clonal aberrations were detected in A-bomb survivors, of which 10 were specifically detected by the method, indicating that its detection rate was 2-3 time as high as the ordinary method. The results were those on the DNA probe on no.1, no.2 and no.3 chromosomes, which consisting of about 23% of the genome. (K.H.)

    The results of the effective use of magnetic laser therapy in the treatment and rehabilitation of cancer patients were presented. The effect of magnetic-laser therapy in the treatment of radiation-induced reactions in the patients with head and neck cancer and in the patients with breast cancer was analyzed. High efficiency of lymphedema and lymphorrhea treatment in the postoperative period in the patients with breast cancer was proved. The results of rehabilitation of the patients with gastric cancer after surgical treatment were presented. These data indicate a high effectiveness of different physical methods of treatment and rehabilitation of cancer patients.

    Full Text Available Objective. To present an unusual but known cause of hypomagnesaemia induced-hypocalcaemia in a chronic GORD patient with severe symptoms with a review of the current literature. Methods. Analysis of the clinical and laboratory findings of the patient and discussion of the multi-factorial nature of his disease and the underlying mechanisms. Results. Our patient described features of magnesium deficiency such as weakness, muscle twitches, and fits with clinical signs of hypocalcaemia: a carpal pedal spasm and paraesthesia. Preadmission blood results revealed low calcium and magnesium levels. He was admitted to ITU, when he presented with seizures and developed encephalopathy. The total vitamin D level was 52.4 nmol/L (>49.9. His U&Es and LFTs were within the normal range with the exception of potassium. He was on Omeprazole for his GORD. With omission of the PPI 1 day after admission and replacement therapy, his ion levels normalised. Conclusion. Hypomagnesaemia is often undiagnosed and is associated with multiple biochemical abnormalities. Treatment focus should be aimed at stopping the PPI and replacing the magnesium. Over use of PPIs is a problem in practice, with the FDA issuing a warning over long-term use. Continued monitoring and decision making on dose reduction/withdrawal is essential to avoid complications.

    Full Text Available Aim: Whether the unaffected function of the hand of patients presenting with nerve injury is affected remains inconclusive. We aimed to evaluate whether there are differences in finger tapping following central or peripheral nerve injury compared with the unaffected hand and the ipsilateral hand of a healthy subject.Methods: 30 right brain stroke patients with hemiplegia, 30 left arm peripheral nerve injury cases and 60 healthy people were selected. We tested finger tapping of the right hands, and each subject performed the test twice.Results: Finger tapping following peripheral nerve injury as compared with the unaffected hand and the dominant hand of a healthy person was significantly higher than was found for central nerve injury (P<0.05. Finger tapping of the male peripheral group’s unaffected hand and the control group’s dominant hand was significantly higher than the central group (P<0.001. However, finger tapping of the female control group’s dominant hand was markedly higher than the central group’s unaffected hand (P<0.01, P=0.002, the peripheral group’s unaffected hand (P<0.05, P=0.034. Conclusion: The unaffected function of the hand of patients with central and peripheral nerve injury was different as compared with the ipsilateral hand of healthy individuals. The rehabilitation therapist should intensify the practice of normal upper limb fine activities and coordination of the patient.

     To compare the predictive accuracy and clinical utility of five risk scoring systems in the assessment of patients with upper gastrointestinal bleeding.  International multicentre prospective study.  Six large hospitals in Europe, North America, Asia, and Oceania.  3012 consecutive patients presenting over 12 months with upper gastrointestinal bleeding.  Comparison of pre-endoscopy scores (admission Rockall, AIMS65, and Glasgow Blatchford) and post-endoscopy scores (full Rockall and PNED) for their ability to predict predefined clinical endpoints: a composite endpoint (transfusion, endoscopic treatment, interventional radiology, surgery, or 30 day mortality), endoscopic treatment, 30 day mortality, rebleeding, and length of hospital stay. Optimum score thresholds to identify low risk and high risk patients were determined.  The Glasgow Blatchford score was best (area under the receiver operating characteristic curve (AUROC) 0.86) at predicting intervention or death compared with the full Rockall score (0.70), PNED score (0.69), admission Rockall score (0.66, and AIMS65 score (0.68) (all P<0.001). A Glasgow Blatchford score of ≤1 was the optimum threshold to predict survival without intervention (sensitivity 98.6%, specificity 34.6%). The Glasgow Blatchford score was better at predicting endoscopic treatment (AUROC 0.75) than the AIMS65 (0.62) and admission Rockall scores (0.61) (both P<0.001). A Glasgow Blatchford score of ≥7 was the optimum threshold to predict endoscopic treatment (sensitivity 80%, specificity 57%). The PNED (AUROC 0.77) and AIMS65 scores (0.77) were best at predicting mortality, with both superior to admission Rockall score (0.72) and Glasgow Blatchford score (0.64; P<0.001). Score thresholds of ≥4 for PNED, ≥2 for AIMS65, ≥4 for admission Rockall, and ≥5 for full Rockall were optimal at predicting death, with sensitivities of 65.8-78.6% and specificities of 65.0-65.3%. No score was helpful at predicting rebleeding or length

    Four and a half LIM protein 1 (FHL1/SLIM1) has recently been identified as the causative gene mutated in four distinct diseases affecting skeletal muscle that have overlapping features, including reducing body myopathy, X-linked myopathy, X-linked dominant scapuloperoneal myopathy and Emery-Dreifuss muscular dystrophy. FHL1 localises to the sarcomere and the sarcolemma and is believed to participate in muscle growth and differentiation as well as in sarcomere assembly. We describe in this case report a boy with a deletion of the entire FHL1 gene who is now 15 years of age and presented with muscle hypertrophy, reduced subcutaneous fat, rigid spine and short stature. This case is the first, to our knowledge, with a complete loss of the FHL1 protein and MAP7D3 in combination. It supports the theory that dominant negative effects (accumulation of cytotoxic-mutated FHL1 protein) worsen the pathogenesis. It extends the phenotype of FHL1-related myopathies and should prompt future testing in undiagnosed patients who present with unexplained muscle hypertrophy, contractures and rigid spine, particularly if male. © 2015 John Wiley & Sons A/S.

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

    2014-12-01

    Full Text Available Non-albicans candida meningitis is a relatively rare disease, with nonspecific clinical manifestation, which makes the misdiagnosis occur sometimes, especially in the early stage of the disease. Abuse of broad-spectrum antibiotics, corticosteroids, central vein cannulas, senility, big operation, malignancy, and total parenteral alimentation were all the susceptible factors of non-albicans candida infection. We present a case of this type of non-albicans infection in a 42-year-old woman who was early misdiagnosed as tuberculous meningitis and was treated with antibiotics and antituberculosis agents. The diagnosis of non-albicans infection was confirmed by fungus culture of the cerebrospinal fluid (CSF with a low detectable rate. This case reminds us that the non-albicans candida meningitis had a nonspecific clinical presentations and laboratory data, and was difficult to differentiate from tuberculosis meningitis. Hence, we should highly suspect this disease if central nervous system infections with uncertain pathogens. Test cell counts; protein and fungus culture of CSF should be used to confirm the diagnosis. Once the diagnosis was established, the patients should receive antifungal treatment based on drug sensitivity tests as early as possible.

    The most common mesenchymal tumour of the gastrointestinal tract is stromal tumours (GISTs). Symptomatic GISTs can present with complications such as haemorrhage, obstruction and perforation. Complete surgical resection with negative margins is the mainstay of treatment but may be imprudent on emergent occasion. Tyrosine-kinase inhibitors (TKIs) have been revolutionary in the treatment of GISTs and have resulted in improved outcomes. A 41 year old HIV positive male presented with an acute history of abdominal pain and obstructive symptoms. Clinical examination revealed sepsis and peritonitis. One of the several small bowel tumours discovered at exploratory laparotomy was necrotic and perforated. The perforated tumour alone was resected and a small bowel internal hernia reduced. The patient made an uneventful recovery and will be considered for TKI therapy with a view to later re-operation. GISTs very rarely perforate. The pathophysiology of stromal tumour necrosis is poorly understood. Multifocality and small bowel location are poor prognosticators and may occur in the setting of familial GISTs, specific syndromes and sporadic cases. There is no established association between HIV and GISTs. Perforation occurs infrequently in ≤8% of symptomatic cases and poses increased risk of local recurrence. The surgical management of perforation takes precedence in an emergency. The surgeon must however take cognisance of the adherence to ideal oncologic principles where feasible. TKI therapy is invaluable if a re-exploration is to be later considered. Copyright © 2014 The Author. Published by Elsevier Ltd.. All rights reserved.

    Fournier gangrene is a rare necrotising fascitis of the perineum and genitals caused by a mixture of aerobic and anaerobic microorganisms. The first case was described by Baurienne in 1764 but the condition was named by Fournier in 1883 who reported the cases of five men with the condition with no apparent etiology. Infection most commonly arises from the skin, urethra, or rectal regions. Despite appropriate therapy, mortality in this disease is still high. We report a case of a low rectal malignancy presenting as Fournier gangrene. This case report serves to highlight an extremely unusual presentation of rectal cancer, a common surgical pathology. The patient is a 48 years old Afghanian male that admitted with Fournier gangrene. In the course of medical and surgical treatment the presence of extensive rectal adenocarcinoma was discovered. After partial recovery, standard loop colostomy was inserted. Skin grafting of necrotic areas was performed and systemic rectal cancer chemotherapy initiated after full stabilization. Fournier gangrene is an uncommon but life threatening condition with high associated mortality and morbidity. Usually there is an underlying cause for the development of Fournier gangrene, that if addressed correctly, can lead to a good outcome. Early diagnosis and treatment decrease the morbidity and mortality of this life threatening condition. Good management is based on aggressive debridement, broad spectrum antibiotics and intensive supportive care.

    The fissile material content in the dissolving or balancing tank of a reprocessing plant has special significance in nuclear fuel balancing. This is the first opportunity for destructive analysis of the fuel content of the material after burn-up of fuel elements in the reactor. In the current state-of-the-art, all balancing methods are based directly or indirectly on data obtained by chemical analysis. The following methods are evaluated: Mass-spectroscopic isotope dilution analysis, X-ray fluorescence spectroscopy, Isotopic correlation, Gamma absorptiometry, Redox titration, Emission spectroscopy after plasma excitation, Alpha spectroscopy, and Laser Raman spectroscopy

    Full Text Available Abstract Introduction Clothing can be a cause of occupational dermatitis. Frequent causes of clothing-related dermatological problems can be the fabric itself and/or chemical additives used in the laundering process, friction from certain fabrics excessively rubbing the skin, or heat retention from perspiration-soaked clothing in hot working environments. To the best of our knowledge, these are the first reported cases of miliaria rubra associated with prolonged use of flame resistant clothing in the medical literature. Case presentation We report 18 cases (14 men and 4 women, with an age range of 19 to 37 years of moderate to severe skin irritation associated with wearing flame resistant clothing in hot arid environments (temperature range: 39 to 50°C, 5% to 25% relative humidity. We describe the medical history in detail of a 23-year-old Caucasian woman and a 31-year-old African-American man. A summary of the other 16 patients is also provided. Conclusions These cases illustrate the potential serious nature of miliaria with superimposed Staphylococcus infections. All 18 patients fully recovered with topical skin treatment and modifications to their dress ensemble. Clothing, in particular blend fabrics, must be thoroughly laundered to adequately remove detergent residue. While in hot environments, individuals with sensitive skin should take the necessary precautions such as regular changing of clothing and good personal hygiene to ensure that their skin remains as dry and clean as possible. It is also important that they report to their health care provider as soon as skin irritation or rash appears to initiate any necessary medical procedures. Miliaria rubra can take a week or longer to clear, so removal of exposure to certain fabric types may be necessary.

    The radiologic evaluation of Hirschsprung disease is well described in the literature. However, there is a paucity of literature describing the appearance of the neo-rectum and colon after repair, specifically describing findings in patients with poor functional outcome, which would suggest the need for reoperation. We describe findings on contrast enema and correlate them with surgical findings at reoperation in children with poor functional outcome after primary repair for Hirschsprung disease who suffer from bowel dysfunction that can manifest with either soiling or obstructive symptoms such as enterocolitis. Children were identified from our colorectal surgery database. At the time of abstract submission, 35 children had contrast enemas prior to reoperation. Additional children continue to present for evaluation. The majority of children included in the study had their primary repair performed elsewhere. The initial procedures included: Duhamel (n = 11), Soave (n = 20) or Swenson (n = 3). One child had undergone a primary Soave repair and subsequently had a Swenson-type reoperation but continued to have a poor outcome. One child's initial surgical repair could not be determined. Images were reviewed by a staff pediatric radiologist and a pediatric radiology fellow. Findings encountered on contrast enema in these children include a distal narrowed segment due to stricture or aganglionic/transitional zone segment (8), dilated/hypomotile distal segment (7), thickened presacral space due to compressing Soave cuff (11), dilated Duhamel pouch (8), active enterocolitis (3) and partially obstructing twist of the pull-through segment (1). Multiple anatomical and pathological complications exist that can lead to bowel dysfunction in children after repair of Hirschsprung disease. Little recent literature exists regarding the radiographic findings in children. We had the opportunity to review a substantial series of these children, describe the contrast enema

    The aim of the work is to optimize the uptake of tin on anion exchange resins and application of this knowledge for the analysis of samples of radioactive waste from the device of Jaslovske Bohunice and Mochovce in determining of 126 Sn. First to be optimized a method for the separation of tin on ion exchange sorbent Anion Exchange Resin (1-X8, Chloride Form) from Eichrom Technologies. Model sample was prepared in 7 mol dm -3 HCl, because in that environment a sorbent effectively captures the tin, which is bounded complexly with chloride anions as SnCl 6 2- . The radiochemical separation yield was monitored by gamma spectrometric measurements on high purity germanium detector HPGe (E = 391 keV) by adding isotope 113 Sn to each model solution. The method of tin separation was optimized on model samples.

    1969-08-01

    A suitable numerical method for integration of one-group integral transport equation is obtained by series expansion of flux and neutron source by radius squared, when calculating the parameters of cylindrically symmetric reactor cell. Separation of variables in (x,y) plane enables analytical integration in one direction and efficient Gauss quadrature formula in the second direction. White boundary condition is used for determining the neutron balance. Suitable choice of spatial points distribution in the fuel and moderator condenses the procedure for determining the transport matrix and accelerates the convergence when calculating the absorption in the reactor cell. In comparison to other collision probability methods the proposed procedure is a simple mathematical model which demands smaller computer capacity and shorter computing time

  13. An effective method of collecting practical knowledge by presentation of videos and related words

    2017-12-01

    Full Text Available The concentration of practical knowledge and experiential knowledge in the form of collective intelligence (the wisdom of the crowd is of interest in the area of skill transfer. Previous studies have confirmed that collective intelligence can be formed through the utilization of video annotation systems where knowledge that is recalled while watching videos of work tasks can be assigned in the form of a comment. The knowledge that can be collected is limited, however, to the content that can be depicted in videos, meaning that it is necessary to prepare many videos when collecting knowledge. This paper proposes a method for expanding the scope of recall from the same video through the automatic generation and simultaneous display of related words and video scenes. Further, the validity of the proposed method is empirically illustrated through the example of a field experiment related to mountaineering skills.

    2013-01-01

    Thesis was focused on the development of a new methodology for the separation of anthropogenic transuranium radionuclides 237 Np a 241 Pu from different kinds of matrices. The analytical methods used in this study were based on extraction chromatography and were optimized according to the sample type. The proposed radiochemical procedure is a combination of two algorithms, which represent the separation of radionuclides by using extraction chromatographic sorbents TEVA resin and TRU resin supplied by Eichrom Technologies LLC. 239 Np a 237 Np were selectively captured on sorbent TEVA resin in oxidation state 4+. TRU resin was used for purification of plutonium fraction from interfering americium radionuclide. 242 Pu and 239 Np radionuclides as tracers have been used to monitor the radiochemical yields of separation. Before every radiochemical separation tracer radionuclide 239 Np was obtained by separation from the parent radionuclide 2 43 Am, which is in radioactive equilibrium to 239 Np. The average yield of chemical separation was 69,3% for 239 Np at 277 keV energy line and 65,9% at 228 keV energy line. The NPL AH-B08069 (2008) samples which consist of the mixture of alpha-radionuclides were used for the modification and optimization of separation method used for separation of Np and Pu in model samples. This method provided high radiochemical yields of 239,240 Pu (95,0 ± 3,5)% and 237 Np (87,9 ± 3,0)%.. Reliability of the method was verified by applying our modified separation procedures on reference materials IAEA-375 and IAEA-414 supplied by International Atomic Energy Agency. A good agreement between the results is obtained by this procedure and the certified values were found. Samples of contaminated soils from the area of Nuclear power plant A-1 Jaslovske Bohunice which is stored temporarily before disposal were analyzed using developed separation procedure. Specific activity of investigated radionuclides was determined in these samples. (author)

    2002-01-01

    A comparison among four extraction techniques such as: liquid - liquid (LLE) continuous and for lots, solid phase extraction (SPE), solid phase micro extraction (SPME) and static headspace (S-HS) was carried out. The main purpose of this research was to determine the highest recovery efficiencies and how reproducible the tests are while varying parameters such as time, extraction technique, type of solvents and others. Chromatographic parameters were optimized in order to carry out the analyses. Hydrocarbon's quantification of residual waters was achieved by using a high-resolution gas chromatography with a gas flame ionization detector (HRGC-FID). Validation of the method was carried out by analyzing real samples taken in different sampling places of the residual waters treatment plant of Ecopetrol - Barrancabermeja. The use of extraction methods that require big solvent quantities and long time for analysis are losing validity day by day. Techniques such as the HS-SPME and static HS are offered as alternatives for quantifying hydrocarbons. They show total lack of solvents, high sensibility, selectivity and the techniques are reproducible. Solid phase micro extraction (SPME) and static headspace (static HS) techniques were chosen as the extraction techniques to validate the method in real samples. Both techniques showed similar results for the determination of total hydrocarbons (in the gasoline range)

  17. Comments on the present state and future directions of PDF methods

    Obrien, E. E.

    1992-01-01

    The one point probability density function (PDF) method is examined in light of its use in actual engineering problems. The PDF method, although relatively complicated, appears to be the only format available to handle the nonlinear stochastic difficulties caused by typical reaction kinetics. Turbulence modeling, if it is to play a central role in combustion modeling, has to be integrated with the chemistry in a way which produces accurate numerical solutions to combustion problems. It is questionable whether the development of turbulent models in isolation from the peculiar statistics of reactant concentrations is a fruitful line of development as far as propulsion is concerned. There are three issues for which additional viewgraphs are prepared: the one point pdf method; the amplitude mapping closure; and a hybrid strategy for replacing a full two point pdf treatment of reacting flows by a single point pdf and correlation functions. An appeal is made for the establishment of an adequate data base for compressible flow with reactions for Mach numbers of unity or higher.

    2011-01-01

    To assess the gender-based differences in the echocardiographic outcomes of patients with mitral stenosis presenting at a tertiary care hospital and the clinical implications of such differences. Methods: A total of 90 echocardiographs of both men and women (aged=15 years) having mitral valve area (MVA) less than 4 cm/sup 2/ were assessed. In addition to MVA, pressure half time and left atrial diameter (LAD) of the patients was also recorded. Other co-existing valvular lesions were also assessed in addition to mitral stenosis. Statistical analysis was done using SPSS-17. Results: A higher prevalence of mitral stenosis (MS) was found in women than men (76.66% vs 24.44%). Men were having more severe mitral stenosis as compared to women (MVA=1.19 cm/sup 2/ vs 1.32 cm/sup 2/). This also resulted in significantly higher left atrial dilatation in males as compared to women (45.09 vs 41.75, p=0.0422). Most of the patients had other coexisting valvular lesions and isolated MS was rare. However, men had a predominance of aortic stenosis along with mitral stenosis (27% vs 4%, p=0.0059) whereas women had a higher prevalence of mitral regurgitation along with mitral stenosis than the men (65% vs 36%, p=0.0258). Conclusion: There were certain significant differences in echocardiographic outcomes of patients based upon their gender. A gender-specific management approach towards the patients with mitral stenosis is essential to have better outcome. (author)

    Full Text Available Objectives: Early diagnosis and emergent surgical debridement of necrotizing soft tissue infections (NSTIs remains the cornerstone of care. We aimed to study the effect of early surgery on patients' outcomes and, in particular, on hospital length of stay (LOS and Intensive Care Unit (ICU LOS. Materials and Methods: Over a 6-year period (January 2003 through December 2008, we analyzed the records of patients with NSTIs. We divided patients into two groups based on the time of surgery (i.e., the interval from being diagnosed and surgical intervention: Early (<6 h and late (≥6 h intervention groups. For these two groups, we compared baseline demographic characteristics, symptoms, and outcomes. For our statistical analysis, we used the Student's t-test and Pearson Chi-square (χ2 test. To evaluate the clinical predictors of early diagnosis of NSTIs, we performed multivariate logistic regression analysis. Results: In the study population (n = 87; 62% males and 38% females, age, gender, wound locations, and comorbidities were comparable in the two groups. Except for higher proportion of crepitus, the clinical presentations showed no significant differences between the two groups. There were significantly shorter hospital LOS and ICU LOS in the early than late intervention group. The overall mortality rate in our study patients with NSTIs was 12.5%, but early intervention group had a mortality of 7.5%, but this did not reach statistical significance. Conclusions: Our findings show that early surgery, within the first 6 h after being diagnosed, improves in-hospital outcomes in patients with NSTIs.

    Full Text Available BACKGROUND Diabetes mellitus has been reported to modify the presenting features of pulmonary tuberculosis. In recent decades, with the increasing prevalence of tuberculosis in diabetes mellitus cases in the world, the relationship is re-emerging as a significant public health problem. Improved understanding of the bidirectional relationship of the two diseases is necessary for proper planning and collaboration to reduce the dual burden of diabetes and TB. MATERIALS AND METHODS The study was conducted at Thanjavur Medical College Hospital during the time period January 2017 to August 2017. It is a prospective study. 60 cases of diabetes mellitus with pulmonary tuberculosis were studied. Their clinical profile and chest radiograph results were analysed. RESULTS The predominant clinical symptoms noted were anorexia (82%, cough (80% and fever (60%. 56% of male patients were smokers. Average duration of diabetes was 68 years. The average fasting and postprandial blood sugar values in the study group was 238.5 and 340.0 mg/dL, respectively. 100% of the patients were sputum positive for AFB. Out of these, 45% of cases were high sputum positivity (3+. Cavitatory lesions (52% were the most common type of lesion noted in both age group patients followed by fibrosis (33% and infiltration (25%. Lower lung field involvement was noted in 32% of patients and was more common in patients greater than 40 years. CONCLUSION Severe hyperglycaemia appears to be a contributory factor to the development of pulmonary tuberculosis in diabetics. This has potentially serious implications for tuberculosis control and it must become a priority to initiate focused and coordinated action like case finding, treatment of latent tuberculosis and efforts to diagnose, detect and treat DM may have a beneficial impact on TB control.

    Full Text Available Background: Obstructive sleep apnea (OSA is often not diagnosed in patients presenting for surgical procedures thereby increasing the incidence of adverse perioperative course. Early diagnosis of this disease is important in modifying anesthetic management as well as utilizing specific means which may decrease the complications and improve the patient outcome. Methods: Patients greater than eighteen years of age, ASA I-III scheduled for elective surgical procedures under anesthesia were randomly selected. Their demographic data, diagnosis and nature of surgery were noted in a semi-structured performa. They were then screened for the presence of OSA with the help of a STOP BANG questionnaire. Results : This study included two hundred four patients randomly selected. Slight female predominance was seen in this sample (55.4%. Mean age of the subjects was 42.7 years (SD=15.08. 24.5% subjects were at high risk for OSA (STOP-BANG>3 with a male predominance (72% versus 37% in low risk group; X 2 =18.62; P<0.001. High risk OSA subjects had higher prevalence of cardiovascular risk factors (57% vs. 11.7% in low risk group; X 2 =33.35; P<0.001. Similarly, this group had a higher prevalence of asthma and chronic obstructive pulmonary disease (COPD (14% versus 3.8% in low risk group; X 2 =6.54; P=0.03. Prevalence of diabetes mellitus (22% and hypothyroidism (6% was also higher in this group (5.2% and 1.9% in low risk group respectively; X 2 =15.42; P<0.001. Conclusion : High degree of suspicion and knowledge of association of OSA and medical diseases may help in detection of such cases and decrease the rate of perioperative complications thus improving patients safety.

    A modified version of the MODerate resolution Imaging Spectroradiometer (MODIS) bidirectional reflectance distribution function (BRDF) algorithm is presented for use in the angular normalization of surface reflectance data gathered by the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) aboard the geostationary Meteosat Second Generation (MSG) satellites. We present early and provisional daily nadir BRDFadjusted reflectance (NBAR) data in the visible and near-infrared MSG channels. These utilize the high temporal resolution of MSG to produce BRDF retrievals with a greatly reduced acquisition period than the comparable MODIS products while, at the same time, removing many of the angular perturbations present within the original MSG data. The NBAR data are validated against reflectance data from the MODIS instrument and in situ data gathered at a field location in Africa throughout 2008. It is found that the MSG retrievals are stable and are of high-quality across much of the SEVIRI disk while maintaining a higher temporal resolution than the MODIS BRDF products. However, a number of circumstances are discovered whereby the BRDF model is unable to function correctly with the SEVIRI observations-primarily because of an insufficient spread of angular data due to the fixed sensor location or localized cloud contamination.

    Full Text Available Objective. To establish whether supplementation with a standard oral dose of Beta-Galactosidase affects hydrogen breath excretion in patients presenting with lactose malabsorption. Methods. Ninety-six consecutive patients positive to H2 Lactose Breath Test were enrolled. Mean peak H2 levels, the time to reach the peak H2, the time to reach the cut-off value of 20 ppm, the cumulative breath H2 excretion, the areas under the curve, and a Visual Analogical 10-point Scale for symptoms were calculated. Genotyping of the C/T-13910 variant was carried out. Results. Following the oral administration of Beta-Galactosidase, in 21.88% of the cases, H2 Lactose Breath Test became negative (Group A, while mean peak H2 levels (74.95 ppm versus 7.85, P<0.0000, in 17.71% (Group B were still positive, with the H2 level 20 ppm above the baseline, but the peak H2 levels were significantly lower than those observed at the baseline test (186.7 ppm versus 66.64, P<0.0000, while in 60.41% (Group C they were still positive with the peak H2 levels similar to those observed at the baseline test (94.43 versus 81.60 ppm. All 96 individuals tested presented the C/C-13910 genotype nonpersistence. Conclusions. The response to oral administration of Beta-Galactosidase in patients with symptoms of lactose malabsorption presents a significant variability.

    Full Text Available Background: Acute undifferentiated febrile illness (AUFI may have similar clinical presentation, and the etiology is varied and region specific. Materials and Methods: This prospective observational study was conducted in a tertiary hospital in South India. All adult patients presenting with AUFI of 3-14 days duration were evaluated for etiology, and the differences in presentation and outcome were analyzed. Results: The study cohort included 1258 patients. A microbiological cause was identified in 82.5% of our patients. Scrub typhus was the most common cause of AUFI (35.9% followed by dengue (30.6%, malaria (10.4%, enteric fever (3.7%, and leptospirosis (0.6%. Both scrub typhus and dengue fever peaked during the monsoon season and the cooler months, whereas no seasonality was observed with enteric fever and malaria. The mean time to presentation was longer in enteric fever (9.9 [4.7] days and scrub typhus (8.2 [3.2] days. Bleeding manifestations were seen in 7.7% of patients, mostly associated with dengue (14%, scrub typhus (4.2%, and malaria (4.6%. The requirement of supplemental oxygen, invasive ventilation, and inotropes was higher in scrub typhus, leptospirosis, and malaria. The overall mortality rate was 3.3% and was highest with scrub typhus (4.6% followed by dengue fever (2.3%. Significant clinical predictors of scrub typhus were breathlessness (odds ratio [OR]: 4.96; 95% confidence interval [CI]: 3.38-7.3, total whole blood cell count >10,000 cells/mm 3 (OR: 2.31; 95% CI: 1.64-3.24, serum albumin <3.5 g % (OR: 2.32; 95% CI: 1.68-3.2. Overt bleeding manifestations (OR: 2.98; 95% CI: 1.84-4.84, and a platelet count of <150,000 cells/mm 3 (OR: 2.09; 95% CI: 1.47-2.98 were independent predictors of dengue fever. Conclusion: The similarity in clinical presentation and diversity of etiological agents demonstrates the complexity of diagnosis and treatment of AUFI in South India. The etiological profile will be of use in the development of

    The present study included 80 patients at the age varying from 24 to 59 years examined at different time (from 3 months to 3 years) after the surgical treatment of herniated intervertebral disks, mostly with clinical signs of L(v)-, S1-root radiculopathy. Coordination gymnastics included a complex of specific isotonico-isometric, isometric, and isotonic exercises designed to affect the deep stabilization system. The exercises were performed in five starting positions in a continuous mode with a small or medium amplitude of the movements synchronized with breathing. It was shown that coordination gymnastics in combination with magnetic therapy and iodine-bromine baths results in the statistically significant relief of pain syndrome (p<0.001) and formation of the muscular corset. Moreover, it increases stability of the vertebral column, improves its adaptation to physical activity, eliminates regional postural imbalance, and promotes formation of the proper movement patterns. Taken together, these effects constitute secondary prophylaxis of vertebrogenic pain syndrome and progressive degenerative changes.

    In the adaptive immune response, the types of cytokines produced define whether there is a cellular (T1) or a humoral (T2) response. Specifically, in the T1 response, interleukin 2 (IL-2), interferon γ (IFN-γ) and tumor necrosis factor β (TNF-β) are produced, whereas in the T2 response, IL-4, IL-5, IL- 6, IL-10 and IL-13 are primarily produced. Cytokines are primarily involved in the regulation of immune system cells. The aim of the present study was to evaluate the cytokine patterns (Type 1/Type 2) and TNF-α expression levels in children with severe gastrointestinal and respiratory bacterial infections. The enzyme-linked immunosorbent assay (ELISA) technique was used to identify the cytokines and the infectious agents. The results obtained demonstrated that, in general, children with bacterial infections experienced an increase in IL-2, IFN-γ and IL-4 concentrations and a decrease in TNF-α, IL-5 and IL-6 concentrations when compared to healthy children. Specifically, type 1 cytokines and an increased TNF-α concentration were found in children with gastrointestinal infections. However, patients with respiratory infections showed increased concentrations of both T2 (IL-4, IL-6 and IL-10) and T1 (IL-2 and IFN-γ) components. Thus, it was concluded that children with gastrointestinal infections exclusively developed a T1 response, whereas children with respiratory infections developed a T1/T2 response to fight the infection.

    There has been several reports of an MND like syndrome in HIV-1 infection, however the data is still sparse. Furthermore, HIV-associated amyotrophic lateral sclerosis (ALS) syndrome differs from the classical ALS in some key aspects.. A 44-year-old male presented with a history of insidious onset and gradually progressive asymmetric weakness of lower limbs. He also complained of thinning in both legs, the left leg more than the right since 1 year along with spontaneous twitching of muscles in both the thighs. On neurological examination, the assessment of higher mental functions was normal. There were no cranial nerve deficits. Motor power was grade 5/5 (Medical Research Council scale) in both the upper limbs and 4+ at hips and knees bilaterally, 5 at right ankle, and 4+ at left ankle. All the deep tendon reflexes were brisk with extensor planter responses. There were no cerebellar signs or sensory deficits. HIV-1 was reactive in enzyme-linked immunosorbent assay. Electrophysiological studies were conducted per the MND protocol.None of the nerves studied showed an abnormal drop in compound muscle action potential amplitude with proximal stimulation. There was evidence of diffuse spontaneous activity, which manifests as fibrillation and fasciculation potentials in most muscles tested . Overall there seems to be sufficient evidence to implicate HIV as a potential cause of an ALS-like disorder, but one must also consider the possibility of coincidental HIV infection in patients who have sporadic ALS. © The Author(s) 2014.

    Lacrimo-auriculo-dento-digital (LADD) syndrome (OMIM #149730) is an autosomal-dominant congenital disorder that can be caused by heterozygous mutations in the tyrosine kinase domains of the genes encoding fibroblast growth factor receptors 2 (FGFR2) and 3 (FGFR3), and has been found in association with a mutation in the FGF10 gene, which encodes an Fgfr ligand. Clinical signs vary, but the condition is characterised by involvement of the lacrimal and salivary systems, cup-shaped ears, hearing loss and dental abnormalities. Additional features may include involvement of the hands and feet with other body systems particularly the kidneys. Previous literature on the subject has been reviewed and this case is the first presentation of LADD syndrome in the Republic of Ireland, as a sporadic case in a 12-year-old girl who exhibited a range of dental and digital anomalies. Her general medical practitioner managed her medical care whilst her oral care necessitated a multidisciplinary approach involving restorative and orthodontic elements. The initial restorative phase of treatment has successfully improved the appearance of the patient's anterior teeth using direct resin composite build-ups.

    This paper discusses the problems with existing fixed-rate price regulation and how a deregulation of both the pipeline and gas utility companies are needed to enhance competition. The paper suggests alternative methods to traditional regulation which include a financial incentive package which allows or encourages utilities to make investments in more efficient energy management, to improve load factors to balance the energy demands between industrial and residential users, and reward purchases of gas supplies that out-perform an agreed upon level of rates of a cost index. Other incentive programs are proposed by the author with a relative detailed discussion on each topic

    Recentry, the tendency to adopt atomic energy owing to the oil shock, the delay in the construction of nuclear power stations worldwide, the uncertainty in the utilization of plutonium, and the prospect of supplying natural uranium are the situations affecting uranium enrichment. Anyway, the enrichment capacity in the world must be increased by the early years of 1980 s. The uranium enrichment technology by centrifugal method is being developed in various countries under strict control of informations, therefore the details are not known, but the general state in Great Britain, F.R. of Germany, Netherlands, U.S.A. and Japan is explained. The development of the centrifugal enrichment method in Japan was designated in 1972 as the national project aiming at operating the enriching plant with international competitive power by 1985. The PNC undertook the development work, and the research and development include the development of a centrifuge, cascade test, life span test, the development of the mass production technology, and safety test. The especially notable matter in this period was the rapid progress of a supercritical type centrifuge. It is judged that the technical basis for constructing a pilot plant has been established. The site for the pilot plant is being prepared now in the Ningyo Pass Mine, PNC, and the enrichment plant with 7000 centrifuges will be constructed there. The outline of the plant and the schedule for the construction are described. (Kako, I.)

    1981-04-01

    Two different numerical methods have been implemented in two computer codes developed in CEA/DRNR, Cadarache, to predict the dynamic response of the containment of Super-Phenix reactor after a hypothetical energy excursion. Both codes are 2D-axisymmetric and solve the time-dependent flow of compressible fluids in the presence of deformable thin structures. The first one, called SIRIUS, uses only Lagrangian meshes; in the second one, called CASSIOPEE, the thick elastic-plastic materials are calculated in Lagrangian coordinates while fluids can be calculated either in Lagrangian or in Eulerian coordinates. The treatment of hydrodynamic, elastic-plastic thick domains then the thin shells models and the fluid-structure couplings are described in parallel for both codes. The efficiency and the limits of the previous methods are finally illustrated by comparison of measured and predicted strains of a vessel issued from one of the MARA experiments which are being purposely performed in Cadarache for validation of these codes in Super-Phenix scale models. These comparisons are encouraging and justify that the Super-Phenix reactor vessel response can be determined using the SIRIUS and CASSIOPEE codes

    Background: Hematopoietic stem cell transplantation (SCT) can be complicated by a variety of live-threatening infectious and non-infectious pulmonary complications. The management of these complications is critically dependent on the most probable diagnosis, which is in part based on imaging work-up. Methods: Systematic review of the literature related to the diagnostic value of high-resolution computed tomography (HRCT) in patients who underwent SCT and developed respiratory symptoms. Results: Literature review did not reveal systematic cohort studies that included patients with respiratory symptoms post-SCT who underwent HRCT and had a well-defined outcome. Most studies selected participants based on their final diagnosis instead of the indication for diagnostic testing in practice. Nevertheless, several papers clearly indicated a potential role for HRCT when complications after SCT occur. A variety of articles described the role of certain HRCT findings in the diagnosis of specific infectious complications, but less data were available for non-infectious complications. Conclusion: We believe more diagnostic studies are needed to determine the value of HRCT for a specific diagnosis in SCT-recipients who present with respiratory symptoms at the transplant clinic. Currently, radiologists should be cautious since HRCT interpretation in these patients is not unambiguous.

    Local and traditional knowledge (LTK) provides rich information about the Arctic environment at spatial and temporal scales that scientific knowledge often does not have access to (e.g. localized observations of fine-scale ecological change potentially from many different communities, or local sea ice and conditions prior to 1950s ice charts and 1970s satellite records). Community-based observations and monitoring are an opportunity for Arctic residents to provide ‘frontline’ observations and measurements that are an early warning system for Arctic change. The Exchange for Local Observations and Knowledge of the Arctic (ELOKA) was established in response to the growing number of community-based and community-oriented research and observation projects in the Arctic. ELOKA provides data management and user support to facilitate the collection, preservation, exchange, and use of local observations and knowledge. Managing these data presents unique ethical challenges in terms of appropriate use of rare human knowledge and ensuring that knowledge is not lost from the local communities and not exploited in ways antithetical to community culture and desires. Local Arctic residents must be engaged as true collaborative partners while respecting their perspectives, which may vary substantially from a western science perspective. At the same time, we seek to derive scientific meaning from the local knowledge that can be used in conjunction with quantitative science data. This creates new challenges in terms of data presentation, knowledge representations, and basic issues of metadata. This presentation reviews these challenges, some initial approaches to addressing them, and overall lessons learned and future directions.

    Spinal epidural abscesses are an uncommon cause of spinal cord injury but, depending on the size and presence of neurological deficits, urgent neurosurgical intervention may be required. We present a unique case of a patient presenting with a spinal epidural collection several days after a fall. While a spinal epidural hematoma was suspected based on the patient's history and MRI findings, a spinal epidural abscess was found during surgery. The patient underwent laminectomy and instrumented fusion with successful treatment of her infection.

    When performing a systematic review, whether or not a meta-analysis is performed, graphical displays can be useful. Data do still need to be described, ideally in graphical form. The Harvest plot has been developed to display combined data from several studies that allows demonstration of not only effect but also study quality. We describe a modification to the Harvest plot that allows the presentation of data that normally could not be included in a forest plot meta-analysis and allows extra information to be displayed. Using specific examples, we describe how the arrangement of studies, height of the bars and additional information can be used to enhance the plot. This is an important development, which by fulfilling Tufte's nine requirements for graphical presentation, allows researchers to display evidence in a flexible way. This means readers can follow an argument in a clear and efficient manner without the need for large volumes of descriptive text. Copyright © 2011 John Wiley & Sons, Ltd.

    1994-01-01

    To realize the corticogram of major sulci and venous system, two different image modalities must be superposed with a minimum error : MRI, MRA and X-Ray angiography. The precise schema of cortical sulci have to become possible with the aid of the IR method of MRI that could clearly identify the sulcal system of the outer and internal surface of the hemisphere. The correspondence of the major venous system of MRI with that of angiography was carried out using several skin markers, bone structures and a deep major venous system. This corticogram was used by the neurosurgeons of the hospital for the electrode placement, the topographical identification of the cortical paroxysms and epilepsy surgery. The best argument for the accuracy of sulcal and venous schema could be offered by somato-sensory evoked potential identifying the central sulcus on the corticogram. (author)

    The neutrons transport theory problems whose solution has been reached were collected in order to show that the transport equation is so complicated that different techniques were developed so as to give approximative numerical solutions to problems concerning the practical application. Such a technique, which had not been investigated in the literature dealing with these problems, is described here. The results which were obtained through this technique in undimensional problems of criticity are satisfactory and speaking in a conceptual way this method is extremely simple because it times. There is no limitation to deal with problems related neutrons sources with an arbitrary distribution and in principle the application of this technique can be extended to unhomogeneous environments.

    Electric power is the most important part of human energy consumption, and since it has a low storage coefficient it is of particular importance to establish a balance in demand and generation in order to modify and optimize consumption patterns. The expression ''Smart Grid'' can be used to describe technologies which are applied for the automation and optimization of the generation, transmission and distribution network management. This technology requires the integration of information and communication technology in electrical network operation. This paper will study how the Smart Grid capabilites can be used to manage and optimize power network consumption, as well as how the consumers collaboration process using an AGC (Automatic Generation Control) system acts to provide secondary frequency control through consumed load shedding. Reestablishing the balance between demand and generation in critical network operation is also investigated. In other words, utilizing the above method, a new system, ADC (Automatic Demand Control), is offered for use alongside the AGC system in Smart Grids to restore the frequency value to its nominal value. This can lead to a more competitive electricity market and reduce the system storage while maintaining adequate security and network reliability. One of the benefits of the proposed methods described in this paper, in addition to restoring the frequency value to its nominal value, is lower costs and a more economic network operation through reducing fuel and CO2 emission by managing and controlling the amount of the consumed load in the Smart Grid. Also consumers are given the capability to have a specific timetable to economize on their energy requirements which will also reduce the load peak and the network losses. (orig.)

    Introduction: Sexual dysfunction can occur due to biological problems, relationship problems, lack of proper sexual knowledge or a combination of these. India is often known as the land of Kamasutra. But as far as sexuality research is concerned, there is a paucity of relevant data from India. In view of this, we conducted a study to assess the psychosocial profile of males presenting with sexual dysfunction to psychiatry out-patient department of a tertiary medical hospital. Materials and Methods: Hundred consecutive male patients presenting with sexual dysfunction were screened using Arizona Sexual Experiences Scale for clinical sexual dysfunction and after obtaining their informed consent were included in this study. They were assessed using a semi-structured proforma, Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision criteria, Mini-International Neuropsychiatric Interview, and Dyadic Adjustment Scale. Results: Majority of our respondents were in the 18–30 years age group and were married. The main source of sex knowledge for 69% of them was peer group. Age of onset of masturbation was 11–13 years for 43% of them. Premature ejaculation was the most common sexual dysfunction seen in the respondents. Marital discord was seen in significantly lesser number of respondents (32.35%) as also major depressive disorder that was seen in only 16%. Discussion: Premature ejaculation was the most common sexual dysfunction in our sample. Despite the sexual dysfunction, marital discord and depression were seen less commonly in our respondents.

    The "knife-cut sign" is a distinctive presentation of linear erosive herpes simplex virus infection in immunocompromised patients. To describe a man whose herpes simplex virus infection-related skin lesions demonstrated the "knife-cut sign" and to review the characteristics of reported immunosuppressed individuals with "knife-cut" cutaneous herpes simplex virus lesions. A man with multiple myeloma and post-stem cell transplant cutaneous graft-versus-host disease managed with systemic prednisone and sirolimus developed disseminated cutaneous herpes simplex virus infection with virus-associated linear ulcers of the inguinal folds and the area between his ear and scalp; the lesions at both sites had a distinctive "knife-cut" appearance. Using the PubMed database, an extensive literature search was performed on herpes simplex virus, immunocompromised patient, and "knife-cut sign". Herpes simplex virus infection-associated skin lesions that demonstrate the "knife-cut sign" present in patients who are immunosuppressed secondary to either an underlying medical condition or a systemic therapy or both. The distinctive virus-related cutaneous lesions appear as linear ulcers and fissures in intertriginous areas, such as the folds in the inguinal area, the vulva, and the abdomen; in addition, other sites include beneath the breast, within the gluteal cleft, and the area between the ear and the scalp. Not only herpes simplex virus-2, but also herpes simplex virus-1 has been observed as the causative viral serotype; indeed, herpes simplex virus-1 has been associated with genital and inframammary lesions in addition to those above the neck. Direct fluorescent antibody testing is a rapid method for confirming the clinically suspected viral infection; however, since false-negative direct fluorescent antibody testing occurred in some of the patients, it may be prudent to also perform viral cultures and possibly lesional skin biopsies to establish the diagnosis.

The potential difference of the following cell is measured: H 2 , Pt, R solution - KCl saturated solution at 25 0 C - X solution, Pt, H 2 - The pH of the reference solution R is known up to 300 0 C and the X solution must have its pH to be determined. The precision of the measures at 300 0 C is estimated about +-0,1 pH unit. The dissociation constant of water is calculated from pH variations of alcaline solutions up to 300 0 C. The method has helped to measure the pH at 300 0 C of some boric acid solutions, with or without lithium hydroxide additions, in the following concentration range: B: 250 to 1500 ppm and Li: 0 to 3 ppm. Some concentrations are in fact those chosen for the primary circuits of pressurized water reactors. The pH of ammoniacal solutions is measured too and helped to determine the variations of the dissociation constant of ammonia with temperature [fr

    Relationships between low back pain (LBP) and the hip in patient cohorts have been described primarily in patients with moderate to severe hip osteoarthritis (OA). Less is known about the links of LBP with hip radiographic findings of hip deformity and minimal OA. To describe the incidence of radiographic hip deformity or hip OA; to describe and compare spine- and hip-related pain and function in the subset of patients who were found to have radiographic hip deformity or hip OA; and to compare patients with evidence of radiographic hip deformity or hip OA to patients without hip radiographic findings. Prospective cohort study with cross-sectional design. Tertiary university. A total of 63 patients (40 women, 23 men) with a mean age of 48.5 ± 14 years with LBP and a minimum of one positive provocative hip test. Hip radiographs were assessed by an independent examiner for hip OA and deformity. Comparisons of hip and lumbar spine pain and function were completed for patients with radiographic findings of hip OA or deformity. Moderate to severe hip OA was found in 12 of 60 patients (20.0%). At least one measurement of femoroacetabular impingement (FAI) was found in 14 of 60 patients (23.3%) to 33 of 45 patients (73.3%). At least one measurement of developmental hip dysplasia (DDH) was found in 7 of 60 patients (11.6%) to 11 of 63 patients (17.4%). Greater pain and reduced hip and lumbar spine function were found in the patients with moderate to severe hip OA. Patients with LBP and FAI were found to have significantly greater extremes of pain and reduced lumbar spine function. Links between the hip and the spine affecting pain and function may be found in patients with LBP and hip deformity and before the onset of radiographic hip OA, and may be associated with hip deformity. Further investigation is needed to better understand these links and their potential impact on prognosis and treatment of LBP. II. Copyright © 2018 American Academy of Physical Medicine and

    A new Glacier Inventory is an indispensable requirement in Italy due to the importance of evaluating the present glacier coverage and the recent changes driven by climate. Furthermore Alpine glaciers represent a not negligible water and touristic resource then to manage and promote them is needed to know their distribution, size and features. The first Italian Glacier Inventory dates back to 1959-1962. It was compiled by the Italian Glaciological Committee (CGI) in cooperation with the National Research Council (CNR); this first inventory was mainly based on field data coupled with photographs (acquired on the field) and high resolution maps. The Italian glaciation resulted to be spread into 754 ice bodies which altogether were covering 525 km2. Moreover in the Eighties a new inventory was compiled to insert Italian data into the World Glacier Inventory (WGI); aerial photos taken at the end of the Seventies (and in some cases affected by a high and not negligible snow coverage) were used as the main source of data. No other national inventory were compiled after that period. Nevertheless during the last decade the largest part of the Italian Alpine regions have produced regional and local glacier inventories which in several cases are also available and queried through web sites and web GIS application. The actual need is now to obtain a complete, homogeneous and contemporary picture of the Italian Glaciation which encompasses the already available regional and local data and all the new updated information coming from new sources of data (e.g.: orthophotos, satellite imagines, etc..). The challenge was accepted by the University of Milan, the EvK2CNR Committee and the Italian Glaciological Committee who, with the sponsorship of Levissima Spa, are presently working to compile the new updated Italian Glacier Inventory. The first project step is to produce a unique homogeneous glacier database including glacier boundary and surface area and the main fundamental

  9. Panel presentation: Should some type of incentive regulation replace traditional methods for regulating LDC's?

    This paper discusses the wants and fears of gas utility companies with regards to incentive regulation. The idea of replacing the traditional rate-of-return regulation with incentive regulation sound very desirous in that it should provide greater management flexibility, quicker and more streamlined regulatory processes, and utility financial rewards based on how well customer needs are met. However, the main fear is that this could result in arbitrary, inappropriate productivity or efficiency targets, or would embody a risk/reward ratio skewed more heavily toward financial penalties than opportunities to increase earnings. The paper presents some of the obstacles of traditional regulation which include a lack of incentive to minimize operational costs; a lack of incentive to introduce new technology, products, or services; prevent the need for flexibility to compete in contestable markets; and the diversion caused by utility managers having to manage the regulatory process rather than delivering value to customers. The paper concludes by comparing the incentive regulation program used in the telecommunications industry to the natural gas industry to demonstrate why the success of the telecommunications model doesn't apply to the gas utilities incentive model

    A radioimmunological method of PGE and PGFα determination has been developed to evaluate their elimination in the urine, one of the best representations of their renal synthesis. The urine is collected for 24 hours at 4 0 C then frozen to -20 0 C until the moment of analysis, which includes a preliminary extraction and chromatographic separation stage. The overall extraction and chromatographic yields are: - 78.7%+-74 (SD) for PGE (n=394) -89%+-4.1 (SD) for PGFα (n=119). The antigen-antibody reaction takes place in PBS-G pH 7.4 buffer under a final volume of 300 μl; incubation proceeds at 4 0 C for 24 hours in the presence of 4.8 pg tritiated PGE 2 or 5.4 pg tritiated PGF 2 α. Immune serum are obtained by immunisation of rabbits with a PG-bovine serumalbumin combination coupled by a carbodiimide. Those used here have an affinity constant and a sensitivity equal respectively to: - 3,7 10 10 l.mole -1 and 1,1 pg for the anti PGE immune serum adopted, - 3,1 10 10 l.mole -1 and 0,9 pg for the anti PGFα immune serum adopted. In view of non-specific interferences due to the organic solvents required for extraction and chromatography the overall sensitivity of the system should be taken as: - 2.2 pg for PGE, - 1.8 pg for PGFα. The intra and intertest reproducibilities are respectively: - 5.6% and 7.8% for PGE, 2.7% and 8.6% for PGFα [fr
