    Splenectomy continues to find common therapeutic indications for hematologic disorders. In addition, recently it is also performed in surgical clinics to assist diagnose of some illnesses. Gaucher's disease, especially Type I, is the most frequently encountered lysosomal storage disorder in man. Manifestations of it are highly variable. The most frequently found symptoms include splenomegaly with anaemia and thrombocytopenia, mostly due to hypersplenism, hepatomegaly and bone disease. Four patients were reported in the present study. Three of them were easily diagnosed with Gaucher's disease via bone marrow cytology, and one with Gaucher's disease was detected by pathological examination following the splenectomy. For the pouse of diagnosis of the Gaucher's disease, performing surgery is generally not necessary. However, for the cases of difficult to diagnose by classical methods, the corect diagnosis of Gaucher's disease can only be made by a special operation.

    Full Text Available Hydronephrosis is the most common abnormal finding in the urinary tract on prenatal screening with ultrasonography (U/S. Hydronephrosis may be obstructive or non-obstructive; obstructive lesions are more harmful to the developing kidneys. The aim of the study was to evaluate the causes of renal pelvic dilatation and the outcome of postnatal treatment in infants with hydronephrosis diagnosed prenatally with U/S. We prospectively studied 67 (60 males newborns with hydronephrosis diagnosed prenatally and confirmed postnatally with U/S from Sept. 2005 to Oct. 2007.

    Background Autopsy identifies lung involvement in 58–92% of patients with the most prevalent forms of systemic amyloidoses. In the absence of lung biopsies, amyloid lung disease often goes unrecognized. Report of a death following transbronchial biopsies in a patient with systemic amyloidosis cautioned against the procedure in this patient cohort. We reviewed our experience with transbronchial biopsies in patients with amyloidosis to determine the safety and utility of bronchoscopic lung biopsies. Methods We identified patients referred to the Amyloidosis Center at Boston Medical Center with lung amyloidosis diagnosed by transbronchial lung biopsies (TBBX). Amyloid typing was determined by immunohistochemistry or mass spectrometry. Standard end organ assessments, including pulmonary function test (PFT) and chest tomography (CT) imaging, and extra-thoracic biopsies established the extent of disease. Results Twenty-five (21.7%) of 115 patients with lung amyloidosis were diagnosed by TBBX. PFT classified 33.3% with restrictive physiology, 28.6% with obstructive disease, and 9.5% mixed physiology; 9.5% exhibited isolated diffusion defects while 19% had normal pulmonary testing. Two view chest or CT imaging identified focal opacities in 52% of cases and diffuse interstitial disease in 48%. Amyloid type and disease extent included 68% systemic AL disease, 16% localized (lung limited) AL disease, 12% ATTR disease, and 4% AA amyloidosis. Fluoroscopy was not used during biopsy. No procedure complications were reported. Conclusions Our case series of 25 patients supports the use of bronchoscopic transbronchial biopsies for diagnosis of parenchymal lung amyloidosis. Normal PFTs do not rule out the histologic presence of amyloid lung disease. PMID:28393574

    We have, in this preliminary study, investigated the use of optical coherence tomography for diagnosis of periodontal disease. We took in vitro OCT images of the dental and periodontal tissues from a young pig and compared them to histological sections. These images distinguish tooth and soft tissue relationships that are important in diagnosing and assessing periodontal disease. We have imaged the attachment of gingiva to the tooth surface and located the cemento-enamel junction. This junction is an important reference point for defining attachment level in the diagnosis of periodontal disease. the boundary between enamel and dentin is also visible for most of the length of the anatomical crown, allowing quantitation of enamel thickness and character.

    Sporadic Creutzfeldt-Jakob disease is a rare neurodegenerative disorder of unknown etiology that causes rapidly progressive dementia. This disease is uniformly fatal and most patients die within 12 months. Clinical findings include myoclonus, visual disturbances, and cerebellar and pyramidal/extrapyramidal signs in addition to rapidly progressive cognitive and functional impairment. These findings are all non-specific and it is often difficult and challenging to diagnose premortem because of low awareness and clinical suspicion. We present a 66-year-old woman with a 5-month history of rapidly progressive dementia. After a series of extensive diagnostic examinations and continuous follow-up, she was diagnosed with probable sporadic Creutzfeldt-Jakob disease based on Centers for Disease Control and Prevention (CDC) criteria, with key findings of rapidly progressive dementia, blurry vision, extrapyramidal signs (cogwheel rigidity), and abnormal hyperintensity signals on diffusion-weighted MRI. Her symptoms progressively worsened and she died 7 months after the onset. The postmortem brain autopsy demonstrated the presence of abnormal protease-resistant prion protein by Western Blot analysis. A literature review was performed on differential diagnoses that present with rapidly progressive dementia and thereby mimic sporadic Creutzfeldt-Jakob disease. These include Alzheimer's disease, dementia with Lewy Bodies, frontotemporal dementia, meningoencephalitis, corticobasal degeneration, progressive supranuclear palsy, CADASIL, and paraneoplastic encephalomyelitis.

    Many veterans of the wars in Afghanistan and Iraq have concomitant respiratory conditions and mental health conditions. We wanted to evaluate the association of mental health diagnoses with respiratory disease diagnoses among post-deployment veterans. We conducted a retrospective cohort study of all Afghanistan and Iraq War veterans who were discharged from the military or otherwise became eligible to receive Veterans Health Administration services. The primary exposure was receipt of a mental health diagnosis and the primary outcome was receipt of a respiratory diagnosis as recorded in the electronic health record. We used multivariable adjusted logistic regression to measure the associations of mental health diagnoses with respiratory diagnoses and conducted several analyses exploring the timing of the diagnoses. Among 182,338 post-deployment veterans, 14% were diagnosed with a respiratory condition, 77% of whom had a concomitant mental health diagnosis. The incidence rates were 5,363/100,000 person-years (p-y), 587/100,000 p-y, 1,450/100,000 p-y, and 233/100,000 p-y for any respiratory disease diagnosis, bronchitis, asthma, and chronic obstructive lung disease diagnoses, respectively, after the date of first Veterans Health Administration utilization. Any mental health diagnosis was associated with increased odds for any respiratory diagnosis (adjusted odds ratio 1.41, 95% confidence interval 1.37-1.46). The association of mental health diagnoses and subsequent respiratory disease diagnoses was stronger and more consistent than the converse. Many Afghanistan and Iraq War veterans are diagnosed with both respiratory and mental illnesses. Comprehensive plans that include care coordination with mental health professionals and treatments for mental illnesses may be important for many veterans with respiratory diseases.

    Cerebellar syndromes result in distinct clinical symptoms, such as ataxia, dysarthria, dysmetria, intention tremor and eye movement disorders. In addition to the medical history and clinical examination, imaging is particularly important to differentiate other diseases, such as hydrocephalus and multi-infarct dementia from degenerative cerebellar diseases. Degenerative diseases with cerebellar involvement include Parkinson's disease, multiple system atrophy as well as other diseases including spinocerebellar ataxia. In addition to magnetic resonance imaging (MRI), nuclear medicine imaging investigations are also helpful for the differentiation. Axial fluid-attenuated inversion recovery (FLAIR) and T2-weighted sequences can sometimes show a signal increase in the pons as a sign of degeneration of pontine neurons and transverse fibers in the basilar part of the pons. The imaging is particularly necessary to exclude other diseases, such as normal pressure hydrocephalus (NPH), multi-infarct dementia and cerebellar lesions. (orig.) [de

    Aerosol burdens and optical properties exhibit substantial spatiotemporal variability, and simulation of current and possible future aerosol burdens and characteristics exhibits relatively high uncertainty due to uncertainties in emission estimates and in chemical and physical processes associated with aerosol formation, dynamics and removal. We report research designed to improve understanding of the causes and characteristics of extreme aerosol optical depth (AOD) at the regional scale, and diagnose and attribute model skill in simulating these events. Extreme AOD events over the US Midwest are selected by identifying all dates on which AOD in a MERRA-2 reanalysis grid cell exceeds the local seasonally computed 90th percentile (p90) value during 2004-2016 and then finding the dates on which the highest number of grid cells exceed their local p90. MODIS AOD data are subsequently used to exclude events dominated by wildfires. MERRA-2 data are also analyzed within a synoptic classification to determine in what ways the extreme AOD events are atypical and to identify possible meteorological `finger-prints' that can be detected in regional climate model simulations of future climate states to project possible changes in the occurrence of extreme AOD. Then WRF-Chem v3.6 is applied at 12-km resolution and regridded to the MERRA-2 resolution over eastern North America to quantify model performance, and also evaluated using in situ measurements of columnar AOD (AERONET) and near-surface PM2.5 (US EPA). Finally the sensitivity to (i) spin-up time (including procedure used to spin-up the chemistry), (ii) modal versus sectional aerosol schemes, (iii) meteorological nudging, (iv) chemistry initial and boundary conditions, and (v) anthropogenic emissions is quantified. Despite recent declines in mean AOD, supraregional (> 1000 km) extreme AOD events continue to occur. During these events AOD exceeds 0.6 in many Midwestern grid cells for multiple consecutive days.

    This paper reports that this discovery study was performed to determine whether extracranial carotid artery plaques could be diagnosed with a new CT technique (spiral CT) that allows nondistorted three-dimensional (3D) reconstructions in the z axis. Twenty carotid arteries were examined with spiral CT in normal volunteers and in patients suspected of having atherosclerotic plaques in the extracranial carotid arteries. The Somatom Plus CT table was advanced at a constant rate, the x-ray tube was continuously rotated, and 3D data were continuously acquired. Sixty milliliters of nonionic contrast medium was injected intravenously previous to and during the acquisition of data. The carotid bifurcations were identified in all patients. Planar images, similar to conventional intraarterial angiograms, were routinely produced from the volumetric CT data

    Full Text Available Retinal diseases such as Age-Related Macular Degeneration (ARMD affect nearly one in three elderly patients. ARMD damages the central vision photoreceptors in the fovea. The Photostress Test is a simple technique for testing for the early effects of ARMD. Here, the illumination sources in a novel self-administered Photostress Testing device were modeled for safety and distribution in illumination software. After satisfying the design constraints in the model, a prototype of the illumination system was fabricated and tested to confirm the modeling results. The resultant prototype can be used to aid in the diagnosis of retinal disease and is well within retinal safety levels.

Randomized controlled study. Suez Canal University Hospital, Ismalia, Egypt. A total of 212 patients with symptoms of LPRD. Patients were evaluated by laryngoscopy, ambulatory pH monitoring for 24 hours, and HPSA testing. Esomeprazole magnesium as a monotherapy was evaluated vs triple therapy in patients with HP infection. To determine the incidence of HPSA in patients with LPRD, and to make a comparison of 2 treatment regimens that have been used based on the presence or absence of HPSA positivity in patients with LPRD. Persistent dry cough and a feeling of a lump in the throat (globus sensation) were the most frequent symptoms of LPRD, while posterior laryngeal inflammation was the main laryngoscopic finding. Results from the HPSA test were positive in 57% of the studied group. Patients with negative HPSA were treated with esomeprazole as single modality with a reported improvement score of 96.6%. Patients with positive HPSA test results were divided into 2 groups: 1 received only esomeprazole, with reported improvement in 40%, whereas the second group was treated with esomeprazole, plus amoxicillin sodium and clarithromycin (triple therapy) and reported a 90% incidence of symptom improvement. The incidence of HP infection in patients with LPRD in our study was 57%. Triple therapy showed a higher cure rate in patients with HPSA-positive test results.

Medical practitioners have to particularly prepare for infectious diseases.  The database of a health care center specialized on tropical medicine was screened for patients with history of migration and one of the following diagnoses: Cystic echinococcosis, tuberculosis, schistosomiasis, visceral leishmaniosis, and neurocysticercosis. Representative casuistics were prepared from select case histories. Radiological pertinent knowledge was compiled based on literature search.  A small selection of frequently imported infectious diseases covers a considerable fraction of health care problems associated with migration. For cystic echinococcosis, schistosomiasis, and neurocysticercosis imaging is the most relevant diagnostic procedure defining also disease stages. Tuberculosis and visceral leishmaniosis are important differentials for malignant diseases.  Imaging plays a meaningful role in diagnosis, treatment stratification, and follow-up of imported infectious diseases. Radiological skills concerning these diseases are important for providing health care for patients in context of migration.   · Imaging plays a meaningful role in multidisciplinary care for imported infectious diseases.. · A small selection covers a considerable fraction of infectious diseases expected in context of migration.. · Stojkovic M, Müller J, Junghanss T et al.

While it is likely that estrogen exposure modifies the risk of various diseases through many different...... mechanisms, some estrogen-related disease processes might work in similar manners and result in association between the diseases. Indeed, the association between diseases need not be due only to estrogen-related factors, but due to similar disease processes from a variety of mechanisms....

  6. Are we diagnosing too many people with coeliac disease?

    Aziz, Imran; Sanders, David S

    2012-11-01

    This review will try to address the question of whether we are diagnosing too many people with coeliac disease. The key reasons for diagnosing coeliac disease may be that it is a common condition affecting up to 1% of the adult population. Delays in diagnosis are common. The average time delay reported by Coeliac UK (National Medical Patient Charity), for patients with symptoms prior to the diagnosis being made is 13 years. For every adult case detected, it is estimated that there are eight cases not detected. Patients with coeliac disease have an associated morbidity and mortality. In addition, quality of life studies suggest that the majority of patients benefit from a gluten-free diet (GFD). Furthermore, the GFD reduces or alleviates the risk of the associated complications. All of these facts could even be used to support the argument for screening! However, conversely the tests for coeliac disease are not 100% sensitive and specific. In addition, we do not know whether patients with milder symptoms will derive less benefit from treatment and are at less risk of complications. Furthermore, evidence presented in this review suggests that actual outcomes for screening studies in an adult population have revealed poor uptake and subsequently difficulties with adherence. What little published data that are available also infers that individuals recognised through screening programmes could have been detected if carefully questioned for symptoms. There is evidence to suggest that diagnosing celiac disease is cost-effective and that the diagnostic costs are offset by reduced medical expenditures, reduced hospital and general practice attendances, but this view depends on the population prevalence of coeliac disease. We believe on the basis of the evidence presented in this review that we are not diagnosing too many adults with coeliac disease. However, the authors consider case-finding with a low threshold for serological testing to be the optimal approach. If you

    Although, divorce is considered to have a negative impact on morbidity, very little is known concerning exposure to divorce and risk of infectious diseases. We aimed to investigate the association between divorce and subsequent hospital contacts with infectious diseases. We performed a nation-wide cohort study, including all Danish men and women (n≈5.6 million) alive on the 1 January 1982 or later, and followed them for infectious disease diagnosed in hospital settings from 1982 to 2010. The association between divorce and risk of infectious diseases was evaluated through rate ratios (RRs) comparing incidence rates of infectious diseases between divorced and married pesons. Compared with married persons, divorced persons were overall at a 1.48 fold (RR=1.48 (95% CI: 1.47-1.50)) increased risk of hospital-diagnosed infectious diseases (RR adjusted for sex, age, period, income and education). The risk of infectious diseases was slightly more pronounced for divorced women (RR=1.54 (1.52-1.56)) than divorced men ((RR=1.42 (1.41-1.44)). The increased risk remained almost unchanged even more than 15 years after the divorce. Young age at divorce, short duration of marriage and number of divorces further increased the risk of infectious diseases, whereas number of children at time of divorce had no impact on risk of hospital-diagnosed infectious diseases following the divorce. Divorce appears to have a moderate but long lasting impact on the risk of infectious diseases the underlying mechanism is unknown but shared risk factors predicting divorce and infectious diseases could contribute to our findings. © 2014 the Nordic Societies of Public Health.

    Full Text Available Abstract Background Reverse transcription-polymerase chain reaction (RT-PCR is the main method for laboratory diagnosis of norovirus-associated infectious intestinal disease (IID. However, up to 16% of healthy individuals in the community, with no recent history of IID, may be RT-PCR positive; so it is unclear whether norovirus is actually the cause of illness in an IID case when they are RT-PCR positive. It is important to identify the pathogen causing illness in sporadic IID cases, for clinical management and for community based incidence studies. The aim of this study was to investigate how faecal viral load can be used to determine when norovirus is the most likely cause of illness in an IID case. Methods Real-time RT-PCR was used to determine the viral load in faecal specimens collected from 589 IID cases and 159 healthy controls, who were infected with genogroup II noroviruses. Cycle threshold (Ct values from the real-time RT-PCR were used as a proxy measure of viral load. Receiver-operating characteristic (ROC analysis was used to identify a cut-off in viral load for attributing illness to norovirus in IID cases. Results One hundred and sixty-nine IID cases and 159 controls met the inclusion criteria for the ROC analysis. The optimal Ct value cut-off for attributing IID to norovirus was 31. The same cut-off was selected when using healthy controls, or IID cases who were positive by culture for bacterial pathogens, as the reference negative group. This alternative reference negative group can be identified amongst specimens routinely received in clinical virology laboratories. Conclusion We demonstrated that ROC analysis can be used to select a cut-off for a norovirus real time RT-PCR assay, to aid clinical interpretation and diagnose when norovirus is the cause of IID. Specimens routinely received for diagnosis in clinical virology laboratories can be used to select an appropriate cut-off. Individual laboratories can use this method to

    Tularemia is a zoonotic infection which is caused by gram negative coccobacilli, Francisella tularensis. The disease occurs after contact with blood and body fluids of infected animals, bites and ingestion of infected food and water. Although it commonly presents with skin lesions, there may also be serious organ involvements. A55-year woman was consulted for presumptive diagnosis of tuberculosis. Multiple lymphadenopathy in right cervical area was present on physical examination. Pleural effusion on left side was detected with computed tomography. In detailed history, knowledge of a family member with the diagnosis of tularemia was obtained. Both of them had the history of contact with infected animals. Diagnosis of tularemia was confirmed with microagglutination test. With this patient who was initially presumptively diagnosed as tuberculosis, we aim to draw attention to diagnosis of tularemia in the presence of pleuropnemonia and peripheral lymphadenopathy and emphasize importance of detailed patient history.

    There is little experience with the effect of pregnancy on Parkinson disease because the number of women with Parkinson disease who are of childbearing age is small. We report four cases beginning during the postpartum period and discuss the potential contribution of different factors that may influence the occurrence of Parkinson disease in this time period. Four women aged 29-35 years developed arm tremor, shoulder pain, dizziness, or decreased dexterity of the hand in the first few days or months after childbirth. They were initially diagnosed with postpartum depression or psychogenic parkinsonism. Finally, dopamine transporter imaging confirmed the diagnosis of young-onset Parkinson disease. Early-onset Parkinson disease may present in postpartum women. In women with atypical motor symptoms in addition to depression, this diagnosis should be considered.

    To estimate renal disease in recently diagnosed hypertensive patients, and to identify factors related to renal disease. Cross-sectional study, with 425 hypertensive patients recently diagnosed in primary health care; renal disease was estimated with serum creatinine, albumin/creatinine index and glomerular filtration rate (GFR). We analyzed cardiovascular risk factors (CRF), subclinical organ injury and cardiovascular disease following the criteria of the 2007 European Guide of Hypertension. Average age: 58,96 +/- 12,73 years old, 63,3% male. We found dyslipemia in 80%, abdominal obesity in 49% and metabolic syndrome in 36% patients. These patients showed increased serum creatinine 3,3%, a reduction in GFR 9,6%, hidden renal disease 6,4%, microalbuminuria 7,5% and nephropathy 2,4%. Hypertensive patients with renal disease (17,88%) were older, with higher systolic pressure, higher incidence of metabolic syndrome, abnormal carotid intima-media thickness and ankle-arm index, and presence of cardiovascular disease. Variables associated with renal disease were metabolic syndrome (odds ratio = 11,12) and ankle-arm index (odds ratio = 17,55). Variables related to creatinina were sex, ankle-arm index and metabolic syndrome; variables related to GFR were sex, age, ankle-arm index, metabolic syndrome and body mass index (BMI); variables related with albumin/creatinine index included diabetes mellitus. Renal disease is detected in about 2 out of 10 hypertensive patients, when, besides serum creatinina, we analyze albumin/creatinine index and GFR. Metabolic syndrome and ankle-arm index are the main variables associated with renal disease. Copyright 2009 Elsevier España, S.L. All rights reserved.

    To describe new options for diagnosis and severity grading of dry eye disease. Perspective on technological advancements to identify tear dysfunction and their value in diagnosing and grading dry eye disease. Evidence is presented on new and evolving technologies to measure tear stability, composition, and meniscus height and their role in dry eye diagnosis and therapeutic efficacy grading is assessed. Evolving concepts regarding pathogenesis and new technologies to evaluate the tears and ocular surface have improved the ability to diagnose, classify, and grade the severity of dry eye disease. New technologies include noninvasive imaging of tear stability and tear meniscus height as a measure of tear volume and tear composition (osmolarity, lacrimal factors, inflammatory mediators, growth and differentiation factors). Approved tests, such as tear osmolarity and tear imaging, are being integrated into clinical practice and may eventually supplant certain traditional tests that have greater variability and less sensitivity. Other tests, such as molecular assays of tears and conjunctival cells, are currently being used in studies investigating pathogenesis and therapeutic mechanism of action. They may eventually translate to routine clinical practice. New technologies have emerged that can noninvasively evaluate the tears and measure disease-associated compositional changes. These tests are being integrated into clinical practice and therapeutic trials for diagnosis, classification, and severity grading of dry eye disease. Copyright © 2014 Elsevier Inc.

    Purpose To assess intracranial visual system changes of newly diagnosed Parkinson disease in drug-naïve patients. Materials and Methods Twenty patients with newly diagnosed Parkinson disease and 20 age-matched control subjects were recruited. Magnetic resonance (MR) imaging (T1-weighted and diffusion-weighted imaging) was performed with a 3-T MR imager. White matter changes were assessed by exploring a white matter diffusion profile by means of diffusion-tensor imaging-based parameters and constrained spherical deconvolution-based connectivity analysis and by means of white matter voxel-based morphometry (VBM). Alterations in occipital gray matter were investigated by means of gray matter VBM. Morphologic analysis of the optic chiasm was based on manual measurement of regions of interest. Statistical testing included analysis of variance, t tests, and permutation tests. Results In the patients with Parkinson disease, significant alterations were found in optic radiation connectivity distribution, with decreased lateral geniculate nucleus V2 density (F, -8.28; P Parkinson disease and that the entire intracranial visual system can be involved. © RSNA, 2017 Online supplemental material is available for this article.

    Full Text Available BACKGROUND: Despite the magnitude and increase of sickness absence due to mental diagnoses, little is known regarding long-term health outcomes. The aim of this nationwide population-based, prospective cohort study was to investigate the association between sickness absence due to specific mental diagnoses and the risk of all-cause and cause-specific mortality. METHODS: A cohort of all 4 857 943 individuals living in Sweden on 31.12.2004 (aged 16-64 years, not sickness absent, or on retirement or disability pension, was followed from 01.01.2005 through 31.12.2008 for all-cause and cause-specific mortality (suicide, cancer, circulatory disease through linkage of individual register data. Individuals with at least one new sick-leave spell with a mental diagnosis in 2005 were compared to individuals with no sickness absence. Hazard ratios (HR and 95% confidence intervals (CI were estimated by Cox regression, adjusting for age, sex, education, country of birth, family situation, area of residence, and pre-existing morbidity (diagnosis-specific hospital inpatient (2000-2005 and outpatient (2001-2005 care. RESULTS: In the multivariate analyses, mental sickness absence in 2005 was associated with an increased risk for all-cause mortality: HR: 1.65, 95% CI: 1.47-1.86 in women and in men: 1.73, 1.57-1.91; for suicide, cancer (both smoking and non-smoking related as well as mortality due to circulatory disease only in men. Estimates for cause-specific mortality ranged from 1.48 to 3.37. Associations with all-cause mortality were found for all mental sickness absence diagnostic groups studied. CONCLUSIONS: Knowledge about the prognosis of patients sickness absent with specific mental diagnoses is of crucial clinical importance in health care. Sickness absence due to specific mental diagnoses may here be used as a risk indictor for subsequent mortality.

  16. Nuclear cardiology procedures to diagnose ischemia in coronary artery disease

    1999-01-01

    Nuclear cardiology is equipped with a broad spectrum of diagnostic capabilities which allow the evaluation of ventricular performance, perfusion and metabolism of the heart. The principle of nuclear medicine procedures consists in the administration of free radioisotopes or radiopharmaceuticals to detect their spatial distribution within the body by detecting their y-rays from outside by gamma cameras. Myocardial perfusion scintigraphy is the most important procedure in nuclear cardiology and is performed on a routine basis with 201 Thallium-Chloride ( 201 Tl) since 1975. With the Single-Photon Emission Computerized Tomography (SPECT) technique it is possible to diagnose ischemia of the left ventricle on the basis of coronary artery disease with a sensitivity of 90-95% and a specificity of about 55%. Recently 99m Tc-tracers were developed for this purpose, which have many advantages due to their better physical properties, their easy handling and availability. The diagnostic accuracy is the same compared to ( 201 Tl). Free fatty acids labeled with 123 Iodine like 123 IPPA are alternative tracers to diagnose ischemia by the metabolic alteration and are pathognomonic tracers to diagnose the heart involvement in myopathies or metabolic defects related to fatty acid degradation which are the main fuel of the normal myocytes. Finally we should not forget the radionuclide ventriculography (RNVG) which is one of the oldest nuclear cardiology procedures providing us with very objective, reliable results of ventricular performance.

    Full Text Available Background: How to manage a late diagnosed Hirschsprung′s disease (HD and how to avoid calibre discrepancy? Subjects and Methods: A retrospective study of all patients diagnosed with HD over 2 years in our hospital from January 2009 to December 2012. Data were analysed for clinical presentations, investigations, surgical procedures and post-operative outcome. Results: Fifteen patients, operated by one single surgeon, were included in this study. The mean age was 6 years (2-16 years. Patients had an ultra-short segment type in 4 cases, rectosigmoid type in 9 cases and descending colonic aganglionosis in 2 cases. Rectal wash out was effective in 12 patients. A blowhole transverse colostomy was performed in 2 patients. Twelve patients underwent one single stage endorectal pull-through. Anastomosis incongruence was avoided by a plication procedure never described before. The assessment of post-operative outcomes by the paediatric incontinence and constipation scoring system revealed a normal continence function in all our patients, but 3 patients suffered from soiling secondary to constipation. Conclusion: One single stage pull-through can be safe and effective in children with late diagnosed HD. Routine rectal washout is a good way to prepare the colon. In some cases, blowhole colostomy can be an option. Anastomosis incongruence is a challenge; we describe a plication procedure to avoid it.

    Full Text Available Pigeon fanciers lung or Bird fanciers lung (BFL is one of the common and preventable causes of hypersensitivity pneumonitis. It is an under diagnosed cause of severe incapacitating breathlessness and can be acute, sub-acute or chronic. We report a case of 53 year old female who presented with severe chronic breathlessness due to regular exposure to pigeons for last 35 years. Clinicians should take a detailed history of exposure in patients with unexplained breathlessness as the avoidance of exposure to the antigens can reverse the disease preventing the morbidity and mortality of the patient.

    Hepatic steatosis is the buildup of lipids within hepatocytes. It is the simplest stage in nonalcoholic fatty liver disease (NAFLD). It occurs in approximately 30% of the general population and as much as 90% of the obese population in the United States. It may progress to nonalcoholic steatohepatitis, which is a state of hepatocellular inflammation and damage in response to the accumulated fat. Liver biopsy remains the gold standard tool to diagnose and stage NAFLD. However, it comes with the risk of complications ranging from simple pain to life-threatening bleeding. It is also associated with sampling error. For these reasons, a variety of noninvasive radiological markers, including ultrasound, computed tomography, magnetic resonance spectroscopy, and the controlled attenuation parameter using transient elastography and Xenon-133 scan have been proposed to increase our ability to diagnose NAFLD, hence avoiding liver biopsy. The aim of this review is to discuss the utility and accuracy of using available noninvasive diagnostic modalities for fatty liver in NAFLD. PMID:25843191

    Lymphogranuloma venereum (LGV) is a sexually transmitted disease, endemic in tropical and subtropical areas for many years. After 2003 there have been several outbreaks in western countries, especially among HIV-positive men who have sex with men (MSM). An important manifestation of LGV is a proctitis, with a clinical presentation and endoscopic findings resembling those of inflammatory bowel diseases (IBDs). LGV is considered new in Scandinavia. This case report focuses on difficulties in differentiating LGV and IBD. This case report used a systematic search in the literature using PubMed and clinical cases from the Department of Infectious Diseases, Copenhagen University Hospital, Rigshospitalet, Denmark (Cases 1-3) and the Section of Surgery, Hamar Hospital, Norway (Case 4). Clinical and endoscopic findings in LGV and IBD resemble each other. All cases were MSM. Three out of four were HIV-positive. Three out of four contacted their general practitioner (GP) due to gastrointestinal (GI) symptoms, and were referred to a gastroenterologist (GE) with suspicion of IBD. Because of non-successful IBD treatment, control of HIV status, relapses of GI-symptoms or extended information concerning sexual habits, LGV was suspected and diagnosed. All patients responded with remission of GI-symptoms and endoscopic findings after oral treatment with doxycycline. Due to similarities between LGV and IBD, LGV should be considered as a differential diagnosis in patients with proctitis or IBD-related symptoms, especially among HIV-positive men. Hence LGV patients may be spared long-lasting examination, mistreatment and surgery.

    Full Text Available Objective. EEG has great potential as a cost-effective screening tool for Alzheimer's disease (AD. However, the specificity of EEG is not yet sufficient to be used in clinical practice. In an earlier study, we presented preliminary results suggesting improved specificity of EEG to early stages of Alzheimer's disease. The key to this improvement is a new method for extracting sparse oscillatory events from EEG signals in the time-frequency domain. Here we provide a more detailed analysis, demonstrating improved EEG specificity for clinical screening of MCI (mild cognitive impairment patients. Methods. EEG data was recorded of MCI patients and age-matched control subjects, in rest condition with eyes closed. EEG frequency bands of interest were θ (3.5–7.5 Hz, α1 (7.5–9.5 Hz, α2 (9.5–12.5 Hz, and β (12.5–25 Hz. The EEG signals were transformed in the time-frequency domain using complex Morlet wavelets; the resulting time-frequency maps are represented by sparse bump models. Results. Enhanced EEG power in the θ range is more easily detected through sparse bump modeling; this phenomenon explains the improved EEG specificity obtained in our previous studies. Conclusions. Sparse bump modeling yields informative features in EEG signal. These features increase the specificity of EEG for diagnosing AD.

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

    Polycystic ovary syndrome (PCOS) and Graves' disease are the common causes of menstrual irregularity leading to infertility in women of child-bearing age. A 21-year-old female patient visited us with complaints of oligomenorrhea and hand tremor. She was diagnosed as having PCOS and hyperthyroid Graves' disease, simultaneously. She had low body weight (BMI: 16.4 kg/m(2)), mild hirsutism, and thyrotoxicosis. The patient was treated with anti-thyroid drug and beta-blocker for about two years, and then recovered to normal thyroid function. Although some studies have suggested a connection between PCOS and autoimmune thyroiditis, no study indicated that PCOS is associated with Graves' disease until now. Here, we describe the first case report of a lean woman with normal insulin sensitivity presenting PCOS and Graves' disease simultaneously.

    In 1817, James Parkinson described the disease which bears his name. The disease was defined as a neurological syndrome characterized by tremor, rigidity, and slowness of movements. Almost one hundred years later, degeneration of neurons in the substantia nigra and low levels of dopamine were identified as the putative cause of the disease, thus the disease remained as a pure neurological disorder. In the late 1990s, non-motor symptoms of the disease began to gain interest because of their clinical relevance, as well as for their potential role in broadening the understanding of the pathophysiological mechanisms involved. In the last decade, focus has shifted to the pre-motor symptoms, those non-motor symptoms that present years before the motor onset of the disease. The main premotor symptoms include rapid eye movement sleep behavior disorder, hyposmia, constipation and depression. Subjects with these symptoms usually are not initially seen by a neurologist, and by the time they are consulted neuronal loss in the substantia nigra is over 50%. This review summarizes the overall relevance of non-motor symptoms, their frequency and their pathophysiological implications. Also, the importance of pre-motor symptoms, and the role of specialists other than neurologists in diagnosing subjects with Parkinson's disease is discussed. Two hundred years after the first description of the disease, it is now evident that Parkinson's disease is a systemic disease and a multispecialty team approach is mandatory. Copyright © 2017 IMSS.

    Psychiatric conditions and not just the treatments themselves might be involved in the pathophysiology of dry eye disease (DED). The aim of our study was to evaluate the association between depression and DED using objective and subjective tests in patients with newly diagnosed depressive disorder who were not using any medication which may help us to determine the sole effect of depression on dry eye. Thirty-six patients from the psychiatry clinic with a new diagnosis of depressive disorder and 32 controls were included in the study. All met the Diagnostic and Statistical Manual IV criteria for depression. Beck Depression Inventory (BDI) was used to measure depression severity and the State-Trait Anxiety Inventory (Stai1, Stai2) for concomitant anxiety symptoms. The Ocular Surface Disease Index (OSDI) and Visual Functioning Questionnaires (VFQ25) were completed and used to confirm diagnosis of DED in conjunction with the tear break up time (TBUT), ocular surface vital dye staining, and Schirmer's test. The comparison of depressive and control groups revealed significantly lower Schirmer (20.3 ± 9.9 vs. 25.7 ± 9.3 mm) and TBUT (7.8 ± 5.7 vs. 12.5 ± 7.8 s) scores with a consistently higher Oxford score (1.8 ± 3.2 vs. 0.2 ± 0.4) in the depressive group. Although the parameters were affected in the depressive group, this did not influence OSDI (86.1 ± 13.6 vs. 86.6 ± 13.3) and VFQ25 (30.8 ± 21.6 vs. 38.5 ± 29.1) scores. In both groups, the three psychological test scores (Stai1-2 and BDI) were correlated to each other but none of these tests were correlated to OSDI, VRQL, Schirmer, TBUT, and Oxford staining scores. Our study shows a definite association between depression and DED. We feel that it is important that psychiatrists take this into account especially while prescribing antidepressants which may aggravate dry eye signs.

    1960-09-14

    In this report evaluation of the death certificates has been on the basis of comparison with recorded autopsy diagnoses without review of the latter. An attempt has been made to evaluate limitations inherent in this method. The cases analyzed here represent the ABCC Hiroshima autopsy series from 1949 through 1959. Post mortem examinations on stillbirths and neonatal deaths that were collected during the years 1948 through 1953 were excluded from consideration because such cases are not pertinent to the general problems under study. With this limitation 1304 cases were available for matching. In 139 of these cases the death certificates were not available through the mechanisms of the overall study, so 1165 cases remained. Before comparisons are made the most important questions that must be answered about the materials and methods of the present investigation are: (1) is the autopsy-death certificate series a representative sample of all deaths in the population; (2) are the autopsy diagnoses correct; (3) are the death certificates properly understood and coded; and (4) are biologically meaningful groupings chosen for comparison between autopsy cause of death and death certificate cause of death. Because it is not possible to provide exact answers to all of these questions the doubt that they raise must be admitted but evaluated in the perspective of that part of the answer which is known.

    Full Text Available Background: Long-term low frequency noise exposure (LFN (≤ 500 Hz, including infrasound may lead to the development of vibroacoustic disease (VAD, a systemic pathology characterized by the abnormal growth of extra-cellular matrices. The respiratory system is a target for LFN. Fibrosis of the respiratory tract epithelia was observed in VAD patients through biopsy, and confirmed in animal models exposed to LFN. Voice acoustic analysis can detect vocal fold variations of mass, tension, muscular and neural activity. Frequency perturbation (jitter, amplitude perturbation (shimmer and harmonicto- noise ratio (HNR are used in the evaluation of the vocal function, and can be indicators of the presence and degree of severity of vocal pathology. Since the respiratory system is the energy source of the phonation process, this raises questions about the effects of VAD on voice production. The purpose of this study was to determine if voice acoustic parameters of VAD patients are different from normative data. Methods: Nine individuals (5 males and 4 females diagnosed with VAD were recorded performing spoken and sung tasks. The spoken tasks included sustaining vowels and fricatives. The sung tasks consisted of maximum phonational frequency range (MPFR. Voice acoustic parameters analysed were: fundamental frequency (F0, jitter, shimmer, HNR and temporal measures. Results: Compared with normative data, both males and females diagnosed with VAD exhibited increased F0, shimmer and HNR. Jitter, MPFR and one temporal measure were reduced. Conclusions: VAD individuals presented voice acoustic parameter differences in spectral, temporal and perturbation measures, which may be indicative of small morphological changes in the phonatory system. Resumo: Enquadramento: A exposição crónica ao ruído de baixa frequência (RBF (≤ 500 Hz, incluindo infra-sons pode conduzir ao desenvolvimento da doença vibroacústica (VAD

    The waterborne diseases are increasing rapidly at an alarming rate in Pakistan due to poor sanitation and unsafe drinking water supplies. This study shows that about 25 percent of all the illnesses in Lahore are due to severe cases of waterborne diseases. Unhygienic sanitation system is the root cause for this scenario. Drinking water, samples were collected from different zones of the city to find out the root cause of waterborne diseases. The samples from the distribution system serving 'Kachi Abbadies' (Underdeveloped areas) were much more contaminated, may be due to non-chlorination as compared to the water which is regularly chlorinated in posh areas of the city. Contribution of soakage pits in groundwater contamination is more significant at shallow depths. From the laboratory results it is clear that water distribution in underdeveloped areas of the city is highly contaminated and ground water available at shallow depth is also infected by microbial activities. Data collected from the different hospitals to investigate the problem shows that waterborne diseases vary their trend seasonally. Here in Pakistan, rainy season (July-August) reveals maximum number of cases of waterborne diseases. Proper sanitation and water supply systems are more essential to control the influence of waterborne diseases within the country. It is strongly recommended that reputable ways of communications are urgently required to highlight the diseases related to unsafe drinking water. (author)

    Anthracnose disease is one of the major economic constraints to chilli production worldwide, especially in tropical and subtropical regions. Accurate taxonomic information is necessary for effective disease control management. In the Colletotrichum patho-system, different Colletotrichum species can be associated with anthracnose of the same host. Little information is known concerning the interactions of the species associated with the chilli anthracnose although several Colletotrichum species have been reported as causal agents of chilli anthracnose disease worldwide. The ambiguous taxonomic status of Colletotrichum species has resulted in inaccurate identification which may cause practical problems in plant breeding and disease management. Although the management and control of anthracnose disease are still being extensively researched, commercial cultivars of Capsicum annuum that are resistant to the pathogens that cause chilli anthracnose have not yet been developed. This paper reviews the causal agents of chilli anthracnose, the disease cycle, conventional methods in identification of the pathogen and molecular approaches that have been used for the identification of Colletotrichum species. Pathogenetic variation and population structure of the causal agents of chilli anthracnose along with the current taxonomic status of Colletotrichum species are discussed. Future developments leading to the disease management strategies are suggested.

    2015-10-21

    Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the industrialized world. The prevalence of NAFLD is increasing, becoming a substantial public health burden. NAFLD includes a broad spectrum of disorders, from simple conditions such as steatosis to severe manifestations such as fibrosis and cirrhosis. The relationship of NAFLD with metabolic alterations such as type 2 diabetes is well described and related to insulin resistance, with NAFLD being recognized as the hepatic manifestation of metabolic syndrome. However, NAFLD may also coincide with endocrine diseases such as polycystic ovary syndrome, hypothyroidism, growth hormone deficiency or hypercortisolism. It is therefore essential to remember, when discovering altered liver enzymes or hepatic steatosis on radiological exams, that endocrine diseases can cause NAFLD. Indeed, the overall prognosis of NAFLD may be modified by treatment of the underlying endocrine pathology. In this review, we will discuss endocrine diseases that can cause NALFD. Underlying pathophysiological mechanisms will be presented and specific treatments will be reviewed.

    Parkinson's disease (PD) is the second most common neurodegenerative disease and has a growing socioeconomic impact due to demographic changes in the industrial nations. There are several forms of PD, a fraction of which (parkinsonism including three autosomal dominantly (SNCA, LRRK2, VPS35) and three autosomal recessively inherited ones (Parkin, PINK1, DJ-1). In addition, there are a plethora of genes causing atypical forms of parkinsonism. In contrast, idiopathic PD is of a multifactorial nature. Genome-wide association studies have established a total of 26 genetic loci for this form of the disease; however, for most of these loci the underlying functional genetic variants have not yet been identified and the respective disease mechanisms remain unresolved. Furthermore, there are a number of environmental and life style factors that are associated with idiopathic PD. Exposure to pesticides and possibly a history of head trauma represent genuine risk factors. Other PD-associated factors, such as smoking and intake of coffee and alcohol may not represent risk factors per se and the cause-effect relationship has not yet been elucidated for most of these factors. A patient with a positive family history and/or an early age of disease onset should undergo counseling with respect to a possible monogenic form of the disease. Disease prediction based on genetic, environmental and life style factors is not yet possible for idiopathic PD and potential gene-specific therapies are currently in the development or early testing phase.

    Full Text Available Fragile X syndrome (FXS is a single-gene disorder with a broad spectrum of involvement, including cognitive and behavioural impairments of varying degrees with specific physical features and with strong association with autism. The study was conducted on 23 males (10-32 years old who had full mutation in the FMR1 gene. A complete medical evaluation, including medical history, family history, psychological testing and physical examination was conducted on each subject. Three of the FXS patients (13% were isolated cases of mental retardation in the family. The remaining 20 FXS patients belonged to 15 families, where there were other mentally retarded family members present. The degree of mental retardation (MR varied. Mild MR was diagnosed in 1/23 (4.35%, moderate MR in 12/23 (52.17%, severe MR in 10/23 (43.48 %. Moreover, autism spectrum disorder was diagnosed in 5/23 (21.74% FXS patients. Analysis of the BMI showed that in FXS patients, 14 of 23 (60.68% had too high body weight - 9/23 (39.13% were overweight and 5/23 (21.74% were obese. The diagnosis of FXS is difficult because of nonspecific symptoms, yet early diagnosis is crucial for early intervention and genetic counseling. The risk of recurrence is 50%.

    The congenital heart disease includes abnormalities in heart structure that occur before birth. Such defects occur in the fetus while it is developing in the uterus during pregnancy. About 500,000 adults have congenital heart disease in USA (WebMD, Congenital heart defects medications, www.WebMD.com/heart-disease/tc/congenital-heart-defects-medications , 2014). 1 in every 100 children has defects in their heart due to genetic or chromosomal abnormalities, such as Down syndrome. The excessive alcohol consumption during pregnancy and use of medications, maternal viral infection, such as Rubella virus, measles (German), in the first trimester of pregnancy, all these are risk factors for congenital heart disease in children, and the risk increases if parent or sibling has a congenital heart defect. These are heart valves defects, atrial and ventricular septa defects, stenosis, the heart muscle abnormalities, and a hole inside wall of the heart which causes defect in blood circulation, heart failure, and eventual death. There are no particular symptoms of congenital heart disease, but shortness of breath and limited ability to do exercise, fatigue, abnormal sound of heart as heart murmur, which is diagnosed by a physician while listening to the heart beats. The echocardiogram or transesophageal echocardiogram, electrocardiogram, chest X-ray, cardiac catheterization, and MRI methods are used to detect congenital heart disease. Several medications are given depending on the severity of this disease, and catheter method and surgery are required for serious cases to repair heart valves or heart transplantation as in endocarditis. For genetic study, first DNA is extracted from blood followed by DNA sequence analysis and any defect in nucleotide sequence of DNA is determined. For congenital heart disease, genes in chromosome 1 show some defects in nucleotide sequence. In this review the causes, diagnosis, symptoms, and treatments of congenital heart disease are described.

    To analyze the relationship between nursing diagnoses and survival rates in children with congenital heart disease. A total of 270 observations were carried out in 45 children with congenital heart disease who were followed for 15 days. Differences in mean survival times were identified in children not more than 4 months of age with respect to the following diagnoses: impaired gas exchange, ineffective breathing pattern, activity intolerance, delayed growth and development, and decreased cardiac output. The main diagnoses are identified early in the hospitalization period and are conditions resulting from hemodynamic alterations and prescribed medical treatment. Congenital heart disease provokes serious hemodynamic alterations that generate human responses, which should be treated proactively.

    Full Text Available Abstract Background A sensitive and analytically specific nucleic acid amplification test (NAAT is valuable in confirming the diagnosis of early Lyme disease at the stage of spirochetemia. Findings Venous blood drawn from patients with clinical presentations of Lyme disease was tested for the standard 2-tier screen and Western Blot serology assay for Lyme disease, and also by a nested polymerase chain reaction (PCR for B. burgdorferi sensu lato 16S ribosomal DNA. The PCR amplicon was sequenced for B. burgdorferi genomic DNA validation. A total of 130 patients visiting emergency room (ER or Walk-in clinic (WALKIN, and 333 patients referred through the private physicians' offices were studied. While 5.4% of the ER/WALKIN patients showed DNA evidence of spirochetemia, none (0% of the patients referred from private physicians' offices were DNA-positive. In contrast, while 8.4% of the patients referred from private physicians' offices were positive for the 2-tier Lyme serology assay, only 1.5% of the ER/WALKIN patients were positive for this antibody test. The 2-tier serology assay missed 85.7% of the cases of early Lyme disease with spirochetemia. The latter diagnosis was confirmed by DNA sequencing. Conclusion Nested PCR followed by automated DNA sequencing is a valuable supplement to the standard 2-tier antibody assay in the diagnosis of early Lyme disease with spirochetemia. The best time to test for Lyme spirochetemia is when the patients living in the Lyme disease endemic areas develop unexplained symptoms or clinical manifestations that are consistent with Lyme disease early in the course of their illness.

    The 'Colour Atlas on Forest Disease' facilitates the diagnosis of syndromes due to different causes in 16 genera or species of forest trees. It contains a selection of more than 200 important, frequent, or conspicuous disease phenomena. These include: in a ratio of 8 percent partly novel, complex diseases due to causes not entirely elucidated, 35 percent known forms of damage of abiotic origin (extreme weather conditions, nutrient deficiency, classical damage due to environmental pollution and de-icing salt, damage through herbicides), and 57 percent diseases and harm of biotic origin (fungal infections, infestation with insect pest, bacterial, mycoplasmal, rickettsia-type and viral diseases, other damage). 418 colour photographs show characteristic features of tree diseases and provide clues to causes and possible alternative diseases liable to be mixed up with the actual one. The selection decided on is restricted to symptoms visible externally in the area of the crowns as far as they are distinguishable in the field. (orig./MG) With 418 colour photographs.

    The radioisotope exercise test is discussed and its benefits characterized for the diagnosis of ischemic heart disease, namely the use of 99m Tc in scintiscanning heart ventricles and of 201 Tl in scintiscanning myocardial perfusion. The exercise ventricular function and perfusion scintigraphies are compared with the common exercise ECG examination, and their superior sensitivity and specificity emphasized. Considering the constraints of scintigraphic imaging, indications are outlined for patients including those with suspect serious ischemic heart disease in whom the exercise ECG test has been negative or inconclusive, patients with the so-called nondiagnostic ECG, patients with atypical symptoms, and healthy individuals for whom the exercise ECG test indicated with respect to their occupation has been positive. Both radionuclide imaging techniques are complementary and are shown to be valuable not only in improving the diagnosis of ischemic heart disease but also in identifying the high-risk patients in whom cardiac surgery is to be considered.

    Cerebellar syndromes result in distinct clinical symptoms, such as ataxia, dysarthria, dysmetria, intention tremor and eye movement disorders. In addition to the medical history and clinical examination, imaging is particularly important to differentiate other diseases, such as hydrocephalus and multi-infarct dementia from degenerative cerebellar diseases. Degenerative diseases with cerebellar involvement include Parkinson's disease, multiple system atrophy as well as other diseases including spinocerebellar ataxia. In addition to magnetic resonance imaging (MRI), nuclear medicine imaging investigations are also helpful for the differentiation. Axial fluid-attenuated inversion recovery (FLAIR) and T2-weighted sequences can sometimes show a signal increase in the pons as a sign of degeneration of pontine neurons and transverse fibers in the basilar part of the pons. The imaging is particularly necessary to exclude other diseases, such as normal pressure hydrocephalus (NPH), multi-infarct dementia and cerebellar lesions. (orig.)

    Full Text Available We describe a patient with acute respiratory insufficiency and difficult ventilator weaning in the ICU ward, leading to diagnosis of small cell lung cancer with superior vena cava superior syndrome. Bilateral vocal cord paralysis caused his respiratory distress and weaning difficulties. Thyroidectomy and neurological problems (such as Parkinson disease and Guillain Barré syndrome are more common causes of bilateral vocal cord paralysis. Lung cancer patients are also at risk due to mediastinal invasion. The left recurrent laryngeal nerve is more prone to paralysis because of the typical anatomy. In contrary, bilateral vocal cord paralysis is rare and doesn't result in speech problems but rather breathing difficulties. Tracheostomy is the classic therapy, but laser cordectomy and Botulinum toxin injection in the laryngeal muscles are alternatives.

The radiation disease acknowledged as professional concerned in 30 cases the skin, in two cases the lungs and in one case each the haematopoietic system, the eyes and the pelvic organs. In 8 indemnified, acute radiation exposure had caused the disease, in 25 the time of exposure had ranged from one year to several decades. The investigation describes when and under what professional circumstances the radiation exposure took place, the course of the disease, what kind of diagnostic and therapeutical measures were carried through and what personal and professional consequences the indemnified sustained. It gives suggestions to set up a future, more effective documentation system on the basis of the experience gathered on the occasion of this investigation with the currently valid registration system, which is unsuitable for further scientific studies, and with the currently practised methods of after-care.

    2012-01-01

    Full Text Available Introduction: Celiac disease (CD is a highly prevalent autoimmune disease. The symptoms of CD are varied and atypical, with many patients having no gastrointestinal symptoms. Metabolic bone disease (MBD is a less recognized manifestation of CD associated with spectrum of musculoskeletal signs and symptoms, viz. bone pains, proximal muscle weakness, osteopenia, osteoporosis, and fracture. We here report five patients who presented with severe MBD as the only manifestation of CD. Materials and Methods: Records of 825 patients of CD diagnosed during 2002-2010 were retrospectively analyzed for clinical features, risk factors, signs, biochemical, and radiological parameters. Results: We were able to identify five patients (0.6% of CD who had monosymptomatic presentation with musculoskeletal symptoms and signs in the form of bone pains, proximal myopathy, and fragility fractures without any gastrointestinal manifestation. All the five patients had severe MBD in the form of osteopenia, osteoporosis, and fragility fractures. Four of the five patients had additional risk factors such as antiepileptic drugs, chronic alcohol consumption, malnutrition, and associated vitamin D deficiency which might have contributed to the severity of MBD. Conclusion: Severe metabolic disease as the only presentation of CD is rare. Patients show significant improvement in clinical, biochemical, and radiological parameters with gluten-free diet, calcium, and vitamin D supplementation. CD should be looked for routinely in patients presenting with unexplained MBD.

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

    Chagas disease (CD), which mostly affects those living in deprived areas, has become one of Latin America's main public health problems. Effective prevention of the disease requires early diagnosis, initiation of therapy, and regular blood monitoring of the infected individual. However, the majority of the Trypanosoma cruzi infections go undiagnosed because of mild symptoms, limited access to medical attention and to a high variability in the sensitivity and specificity of diagnostic tests. Consequently, more affordable and accessible detection technologies capable of providing early diagnosis and T. cruzi load measurements in settings where CD is most prevalent are needed to enable enhanced intervention strategies. This work analyzes the potential contribution of biosensing technologies, reviewing examples that have been tested and contrasted with traditional methods, both serological and parasitological (i.e., molecular detection by PCR), and discusses some emerging biosensing technologies that have been applied for this public health issue. Even if biosensing technologies still require further research efforts to develop portable systems, we arrive at the conclusion that biosensors could improve the accuracy of CD diagnosis and the follow-up of patients' treatments in terms of the rapidity of results, small sample volume, high integration, ease of use, real-time and low cost detection when compared with current conventional technologies.

    2014-03-07

    During 2010, approximately 6,091 persons aged ≥18 years in Puerto Rico were living with end-stage renal disease (ESRD) (i.e., kidney failure that requires regular dialysis or kidney transplantation for survival). This included 1,462 persons who began treatment for ESRD in 2010. Diabetes is the leading cause of ESRD in Puerto Rico, accounting for 66% of new cases in adults, followed by hypertension, which accounts for 15% of the cases. Although the number of adults initiating ESRD treatment (i.e., dialysis or kidney transplantation) in Puerto Rico each year who have diabetes listed as a primary cause (ESRD-D) has increased since 1996, ESRD-D incidence among adults with diagnosed diabetes has not shown a consistent trend. To assess recent trends in ESRD-D incidence among adults aged ≥18 years in Puerto Rico with diagnosed diabetes and to further examine trends by age group and sex, CDC analyzed 1996-2010 data from the U.S. Renal Data System (USRDS) and the Behavioral Risk Factor Surveillance System (BRFSS). After increasing in the late 1990s, ESRD-D incidence decreased during the 2000s among adult men and among persons aged 18-44 years with diagnosed diabetes in Puerto Rico. Throughout the period, ESRD-D incidence among adult women and among persons aged 45-64 and ≥75 years with diagnosed diabetes did not show a consistent trend, and ESRD-D incidence among persons aged 65-74 years with diagnosed diabetes increased. Increased awareness of the risk factors for kidney disease and implementation of effective interventions to prevent or delay kidney disease among persons with diagnosed diabetes might decrease ESRD incidence in Puerto Rico, particularly among women and older persons.

  20. Collapse of a historic oyster fishery: diagnosing causes and identifying paths toward increased resilience

    Full Text Available Diagnosing causal factors of change at the ecosystem level is challenging because multiple drivers often interact at various spatial and temporal scales. We employ an integrated natural and social science approach to assess potential mechanisms leading to the collapse of an estuarine social-ecological system, and recommend future paths to increased system resilience. Our case study is the collapse of the eastern oyster (Crassostrea virginica fishery in Apalachicola Bay, Florida, USA, and the associated impacts on local resource dependent communities. The oyster fishery collapse is the most recent in a series of environmental stressors to this region, which have included hurricanes and tropical storms, drought, and the Deepwater Horizon oil spill. We found it likely that the oyster collapse was not related to contamination from the recent oil spill, but rather to factors affecting oyster recruitment and survival, which may have been mediated by both human, e.g., fishing-related habitat alteration, and environmental, e.g., increased natural mortality from predators and disease, factors. The relative impact of each of these factors is likely to increase in the future because of changing climate and increased demand for fishery, water, and petroleum resources. Successful restoration and persistence of a viable oyster fishery will depend on: (1 implementation of some minimal best management practices, e.g., extensive habitat restoration via shell addition, and some spatial closures to harvest, (2 improving environmental knowledge and promoting episodic learning through enhanced monitoring and experimental management, and (3 continued community engagement necessary to produce adaptable governance suitable to responding to future unexpected challenges.

    Risk perception and psychological concerns are relevant for understanding how people view Lyme disease. This study investigates the four separate outcomes of susceptibility, likelihood to be diagnosed, worry, and fear for contracting Lyme disease. University students (n=713) were surveyed about demographics, perceived health, Lyme disease knowledge, Lyme disease preventive behaviors, Lyme disease history, and Lyme disease miscellaneous variables. We found that women were associated with increased susceptibility and fear. Asian/Asian-American race/ethnicity was associated with increased worry and fear. Perceived good health was associated with increased likelihood to be diagnosed, worry, and fear. Correct knowledge was associated with increased susceptibility and likelihood to be diagnosed. Those who typically spend a lot of time outdoors were associated with increased susceptibility, likelihood to be diagnosed, worry, and fear. In conclusion, healthcare providers and public health campaigns should address susceptibility, likelihood to be diagnosed, worry, and fear about Lyme disease, and should particularly target women and Asians/Asian-Americans to address any possible misconceptions and/or offer effective coping strategies.

    Adriana Bastos Conforto

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

  4. DIAGNOSIS OF ENDOCRINE DISEASE: Expanding the cause of hypopituitarism.

    2017-06-01

    Hypopituitarism is defined as one or more pituitary hormone deficits due to a lesion in the hypothalamic-pituitary region. By far, the most common cause of hypopituitarism associated with a sellar mass is a pituitary adenoma. A high index of suspicion is required for diagnosing hypopituitarism in several other conditions such as other massess in the sellar and parasellar region, brain damage caused by radiation and by traumatic brain injury, vascular lesions, infiltrative/immunological/inflammatory diseases (lymphocytic hypophysitis, sarcoidosis and hemochromatosis), infectious diseases and genetic disorders. Hypopituitarism may be permanent and progressive with sequential pattern of hormone deficiencies (radiation-induced hypopituitarism) or transient after traumatic brain injury with possible recovery occurring years from the initial event. In recent years, there is increased reporting of less common and less reported causes of hypopituitarism with its delayed diagnosis. The aim of this review is to summarize the published data and to allow earlier identification of populations at risk of hypopituitarism as optimal hormonal replacement may significantly improve their quality of life and life expectancy. © 2017 European Society of Endocrinology.

  5. Bayesian comparison of cost-effectiveness of different clinical approaches to diagnose coronary artery disease

    The objective of this study was to compare the cost-effectiveness of four clinical policies (policies I to IV) in the diagnosis of the presence or absence of coronary artery disease. A model based on Bayes theorem and published clinical data was constructed to make these comparisons. Effectiveness was defined as either the number of patients with coronary disease diagnosed or as the number of quality-adjusted life years extended by therapy after the diagnosis of coronary disease. The following conclusions arise strictly from analysis of the model and may not necessarily be applicable to all situations. As prevalence of coronary disease in the population increased, it caused a linear increase in cost per patient tested, but a hyperbolic decrease in cost per effect, that is, increased cost-effectiveness. Thus, cost-effectiveness of all policies (I to IV) was poor in populations with a prevalence of disease below 10%. Analysis of the model also indicates that at prevalences less than 80%, exercise thallium scintigraphy alone as a first test (policy II) is a more cost-effective initial test than is exercise electrocardiography alone as a first test (policy I) or exercise electrocardiography first combined with thallium imaging as a second test (policy IV). Exercise electrocardiography before thallium imaging (policy IV) is more cost-effective than exercise electrocardiography alone (policy I) at prevalences less than 80%. 4) Noninvasive exercise testing before angiography (policies I, II and IV) is more cost-effective than using coronary angiography as the first and only test (policy III) at prevalences less than 80%. 5) Above a threshold value of prevalence of 80% (for example patients with typical angina), proceeding to angiography as the first test (policy III) was more cost-effective than initial noninvasive exercise tests (policies I, II and IV)

    With a substantial increase in diagnosed Parkinson's disease, it is of great importance to examine tolerance and physical measures of evolving exercise interventions. Of particular importance, a multifaceted exercise intervention combining active-assisted cycling and resistance training to older adults diagnosed with Parkinson's disease is being assessed. Fourteen older adults diagnosed with Parkinson's disease and ten healthy older adults (67.5 ± 7.9 years of age) engaged in an 8-week, 24-session, multifaceted exercise protocol. The protocol consisted of both active-assisted cycling and resistance training. Tolerance was measured, as well as multiple indicators of health-related physical fitness. These indicators examined improvements in cardiovascular performance, muscular strength, muscular endurance, and flexibility. Twenty-two older adults and older adults diagnosed with Parkinson's disease tolerated the intervention by completing all 24 sessions. Repeated-measures analysis of variance demonstrated significant (P ≤ 0.003) improvements in cardiovascular performance, muscular strength, muscular endurance, and flexibility for both groups of individuals. The multifaceted intervention is the first to combine both active-assisted cycling and resistance training. The older adult and the older adult diagnosed with Parkinson's disease exhibited both tolerance and health-related improvements in physical fitness following the intervention.

    Connective tissue diseases (CTDs) of childhood are rare inflammatory disorders, involving various organs and tissues including respiratory system. Pulmonary involvement in patients with CTDs is uncommon but may cause functional impairment. Data on prevalence and type of lung function abnormalities in children with CTDs are scarce. Thus, the aim of this study was to asses pulmonary functional status in children with newly diagnosed CTD and follow the results after two years of the disease course. There were 98 children (mean age: 13 ± 3; 76 girls), treated in Department of Pediatric Rheumatology, Institute of Rheumatology, Warsaw and 80 aged-matched, healthy controls (mean age 12.7 ± 2.4; 50 girls) included into the study. Study procedures included medical history, physical examination, chest radiograph and PFT (spirometry and whole body-plethysmography). Then, the assessment of PFT was performed after 24 months. FEV₁, FEV₁/FVC and MEF50 were significantly lower in CTD as compared to control group, there was no difference in FVC and TLC. The proportion of patients with abnormal lung function was significantly higher in the study group, 41 (42%) vs 9 (11%). 24-months observation didn't reveal progression in lung function impairment. Lung function impairment is relatively common in children with CTDs. Although restrictive ventilatory pattern is considered typical feature of lung involvement in CTDs, airflow limitation could also be an initial abnormality.

    Full Text Available Scheuermann’s disease (SD or vertebral osteochondrosis is the most frequent cause of non postural kyphosis and one of more frequent cause of adolescent’s dorsalgia. The criteria for the diagnosis are: more than 5° of wedging of at least three adjacent vertebrae at the apex of the kyphosis; a toracic kyphosis of more than 45° of Cobb’s degree; Schmorl’s nodes and endplates irregularities. In addition to classic SD, there are radiological alterations that remain asintomatic for a long time to reveal in adult age: in that case it speaks of adult Scheuermann’s disease (ASD. We considered the diagnosis of patients came from April 2006 to April 2007 on Day Hospital in our Clinic. ASD was diagnosed, besides, in 10 of these patients. 7 patients had previous diagnosis such as: dorsal Spondiloarthrosis (4 subjects; Osteoporosis with vertebral fractures (3 subjects. All these diagnosis was not confirmed by us. In case of chronic dorsalgia of adult, ASD is rarely considered as differential diagnosis. Besides, the vertebral dorsalgia, even in absence of red flags as fever, astenia, ipersedimetry, functional loss and aching spinal processes to tapping, could hide a serious scene that lead us to be careful in the differential diagnosis, because of similar radiological pictures of the MSA to other pathology as spondylodiscitis, primitive or metastasic spinal tumors, and brittleness vertebral fractures

    The association between celiac disease and eating disorders has been very rarely reported. This is the first report on celiac disease associated with bulimia in this part of Europe. An adult female patient with history of bulimia and one uncomplicated pregnancy was admitted to the Gastroenterology Department, due to long lasting dyspeptic symptoms, constipation, major weight loss and fatigue. After positive serological screening, the diagnosis of celiac disease was confirmed with histopathology examination of duodenal biopsy specimen. Complicated interactions between celiac disease and bulimia can make them difficult to diagnose and treat. It is important to consider the presence of celiac disease in patients with bulimia and gastrointestinal symptoms.

    Head-to-head comparison of ultrasound and CT accuracy in common diagnoses causing acute abdominal pain. Consecutive patients with abdominal pain for >2 h and <5 days referred for imaging underwent both US and CT by different radiologists/radiological residents. An expert panel assigned a final diagnosis. Ultrasound and CT sensitivity and predictive values were calculated for frequent final diagnoses. Effect of patient characteristics and observer experience on ultrasound sensitivity was studied. Frequent final diagnoses in the 1,021 patients (mean age 47; 55% female) were appendicitis (284; 28%), diverticulitis (118; 12%) and cholecystitis (52; 5%). The sensitivity of CT in detecting appendicitis and diverticulitis was significantly higher than that of ultrasound: 94% versus 76% (p < 0.01) and 81% versus 61% (p = 0.048), respectively. For cholecystitis, the sensitivity of both was 73% (p = 1.00). Positive predictive values did not differ significantly between ultrasound and CT for these conditions. Ultrasound sensitivity in detecting appendicitis and diverticulitis was not significantly negatively affected by patient characteristics or reader experience. CT misses fewer cases than ultrasound, but both ultrasound and CT can reliably detect common diagnoses causing acute abdominal pain. Ultrasound sensitivity was largely not influenced by patient characteristics and reader experience. (orig.)

  13. Substance abuse as a cause of violence in persons diagnosed with schizophrenia

    2013-01-01

    Full Text Available Persons diagnosed with schizophrenia can both inflict and suffer violence. For centuries there has been a firmly held belief that they are dangerous and, due to this belief, they are still frequently isolated from the community and exposed to involuntary treatment and restraint. Research data illustrates that persons with this diagnosis are at greater risk of performing violent acts more frequently than the general population. In recent years, the general framework has been set in a more complex manner due to the inclusion in analysis of several mediating variables such as gender, social status, childhood trauma, personality traits, stress and many others. Numerous studies have shown that violent tendencies are evident in persons with co-morbidity of schizophrenia and anti- social personality disorder and/or substance abuse disorders. This paper is focused on reviewing data scrutinizing the role of drug abuse and alcoholism in the violent behavior of persons diagnosed with schizophrenia. Data obtained through meta- analyses of tens of thousands of cases demonstrates unequivocally that the percentage of persons with schizophrenia who commit violent acts without abusing drugs is relatively higher than in the general population (8.5% : 5.3%, while persons who abuse drugs and/or alcohol have been more frequently violent regardless of being psychotic or not (27.6%. Having taken these findings into account, the understanding that persons diagnosed with schizophrenia are prone to violence must be made more specific and their treatment, follow- up and public image changed accordingly. Some of these implications are discussed in this paper and changes suggested.

    Caroli's disease, which is a rare condition with congenital dilatation if the intrahepatic bile ducts, is usually diagnosed postoperatively. The clinical suspicion in a patient with gallstones and choledocholithiasis presenting with dilated intrahepatic biliary radicles and jaundice is usually an obstructive etiology. However, scintigraphic evaluation of this entity, as in this case, gives additional information on liver function, biliary drainage and predisposing conditions like Caroli's disease, which could be missed otherwise

    Expert system is dealt with system that used computer-based human intelligence to overcome particular problem which is commonly conducted by an expert. Frequent problem faced by the farmers of oil palm is the difficulty in defining the type of plant disease. As a result, the delay treatment of plant disease brings out the declining of farm products. An application system is needed to deal with the obstacles and diagnosing the type of oil palm plant disease. The researcher designed an intelligence-based application with input-output plan which is able to diagnose the type of oil palm plant disease by applying naive bayes method. Based on the research result by conducting bayes method with recognized symptom, diagnose of oil palm plant disease could be accomplished. The data of symptoms found are leaves turned yellow 0.4, dead leaves 0.4, black and brown color among the veins of leaves 0.5, young and old fruit with whole space 0.4, and decay of bunches is 0.3. The roots are tender in the amount of 0.5, and damage on sheath is 0.3. Through the chosen symptoms as mentioned above, the value of bayes is 80% with the type of disease is rotten bunch.

    Full Text Available Background. Insomnia and disability pension are major health problems, but few population-based studies have examined the association between insomnia and risk of disability pension. Methods. We conducted a prospective nationwide cohort study based on Swedish population-based registers including all 5,028,922 individuals living in Sweden on December 31, 2004/2005, aged 17–64 years, and not on disability or old age pension. Those having at least one admission/specialist visit with a diagnosis of disorders of initiating and maintaining sleep (insomnias (ICD-10: G47.0 during 2000/2001–2005 were compared to those with no such inpatient/outpatient care. All-cause and diagnosis-specific incident disability pension were followed from 2006 to 2010. Incidence rate ratios (IRRs and 95% confidence intervals (CIs were estimated by Cox regression. Results. In models adjusted for prior sickness absence, sociodemographic factors, and inpatient/specialized outpatient care, associations between insomnia and increased risks of all-cause disability pension (IRR 1.35, 95% CI 1.09–1.67 and disability pension due to mental diagnoses (IRR 1.86, 95% CI 1.38–2.50 were observed. After further adjustment for insomnia medications these associations disappeared. No associations between insomnia and risk of disability pension due to cancer, circulatory, or musculoskeletal diagnoses were observed. Conclusion. Insomnia seems to be positively associated with all-cause disability pension and disability pension due to mental diagnoses.

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

    This discussion paper describes a new and comprehensive model for diagnosing the causes of individual medical performance problems: SKIPE (skills, knowledge, internal, past and external factors). This builds on a previous paper describing a unifying theory of clinical practice, the RDM-p model, which captures the primary skill sets required for effective medical performance (relationship, diagnostics and management), and the professionalism that needs to underpin them. The SKIPE model is currently being used, in conjunction with the RDM-p model, for the in-depth assessment and management of doctors whose performance is a cause for concern.

    We herein report a case of Addison's disease caused by tuberculosis characterized by atypical hyperpigmentation, noted as exacerbation of the pigmentation of freckles and the occurrence of new freckles, that was diagnosed in the presence of active pulmonary tuberculosis. The clinical condition of the patient was markedly ameliorated by the administration of hydrocortisone and anti-tuberculosis agents. When exacerbation of the pigmentation of the freckles and/or the occurrence of new freckles are noted, Addison's disease should be considered as part of the differential diagnosis. In addition, the presence of active tuberculosis needs to be assumed whenever we treat patients with Addison's disease caused by tuberculosis, despite its rarity.

This is a cross-sectional study of 227 newly-diagnosed, antiretroviral naïve patients with HIV/AIDS seen at the HIV clinic of the Medical Out-patient Department (MOPD) of University of Ilorin Teaching Hospital (UITH). They were matched with 108 control group. Laboratory investigations were performed for the participants. CKD was defined as estimated glomerular filtration rate (eGFR) 30 mg/g. There were 100 (44%) males among the patients and 47 (43.5%) among the control group. The mean ages of the patients and controls were 40.3 ± 10.3 years and 41.8 ± 9.5 years respectively. CKD was observed in 108 (47.6%) among the patients and 18 (16.7%) of the controls (p = 0.01). The median CD4 T-cell count was significantly lower in patients with CKD. Ninety-three (41.0%) of the patients had dipstick proteinuria of > 2 +. The median albumin creatinine ratio (ACR) was significantly higher among the HIV-positive patients (272.3 mg/g) compared with the HIV-negative controls (27.22 mg/g) p = 0.01. The CD4 T-cell count correlates positively with eGFR (r = 0.463, p = 0.001) and negatively with ACR (r = -0.806, p = 0.001). CKD is very common among patients with HIV/AIDS in Ilorin. Screening and early intervention for CKD should be part of the protocols in the management of these patients.

    BACKGROUND: Epidemiologic shift with rising incidence of Crohn\\'s disease (CD) has been reported in recent studies. AIMS: To determine disease behaviour and therapeutic interventions undertaken in newly diagnosed patients with CD. METHODS: Patients diagnosed with CD between January 2006 and June 2008 were included. Disease type, location, degree of involvement and type of therapeutic interventions were recorded. RESULTS: A total of 78 patients were included. Colonic, ileo-colonic, terminal ileal and isolated small bowel disease were present in 37, 27, 9 and 5 patients, respectively. Disease phenotype was inflammatory, stenosing and fistulising in 42, 30 and 6 patients, respectively. Surgery was required in 22 patients, including right hemicolectomy (n = 8), subtotal colectomy (n = 4), segmental colonic resection (n = 2), segmental small bowel resection (n = 2), appendectomy (n = 2) and perianal surgery (n = 4). Fourteen patients underwent surgery at the time of diagnosis. Laparoscopic surgery was performed in 14 patients. CONCLUSIONS: A significant proportion of newly diagnosed patients with CD underwent surgical intervention on their first admission to hospital. This may signify a changing trend in the management approach.

    Hydrocephalus is a common neurological disorder in children and the result of a variety of causes. However, with the advancement of imaging modalities, particularly MRI, previously reported rarer causes of hydrocephalus in children are now being more readily appreciated. We report an 11-year-old boy with diffuse villous hyperplasia of the choroid plexus. He had a ventriculo-peritoneal (VP) shunt in-situ and a prior diagnosis from infancy of congenital aqueduct stenosis as the cause of his hydrocephalus. His current presentation was with further shunt dysfunction. CT and MRI demonstrated enlarged choroid plexuses but did not confirm aqueduct stenosis. CSF overproduction was demonstrated from the externalized ventricular drain. The enlarged choroid plexuses were surgically resected and histology confirmed choroid plexus hyperplasia. Identification of choroid plexus hyperplasia is important since the neurosurgical management of hydrocephalus is not VP shunt insertion, but resection of the hyperplastic choroid plexus. (orig.)

    2009-10-01

    Moyamoya disease is a rare, progressive disease of the vessels diagnosed according to characteristic abnormalities of brain arteries in the angiography. The incidence of moyamoya disease in Europe is lower than in Asia and its clinical course in European population is probably different from Asiatic (older age of onset and rare incidence of hemorrhagic strokes). Two young patients were diagnosed as moyamoya disease on the basis of clinical symptoms (ischaemic stroke) and results of brain vessels' angiography, which documented an occlusion of both internal carotid arteries above branching-off the ocular arteries in the first patient and stenosis of distal internal carotid arteries and proximal medial and anterior cerebral arteries in the second one. Both patients are under control of the Neurological Outpatient Department and their neurological state is stable. Despite that moyamoya disease is a rare cause of ischaemic stroke, it should be always considered as one of etiologic factors, especially in young patients.

    Background Chronic obstructive pulmonary disease is a leading cause of mortality, and associated with increased healthcare utilization and healthcare expenditure. In several countries, morbidity-based systems have changed the way resources are allocated in general practice. In primary care, fee......-for-services tariffs are often based on political negotiation rather than costing systems. The potential for comprehensive measures of patient morbidity to explain variation in negotiated expenditures for patients with chronic obstructive pulmonary disease has not previously been examined. The aim of this study...... is to analyze fee-for-service expenditure of patients diagnosed with chronic obstructive pulmonary disease visiting Danish general practice clinics and further to assess what proportion of fee-for-service expenditure variation was explained by patient morbidity and general practice clinic characteristics...

    Castleman's disease is a rare benign lymphoproliferative disorder, characterized by benign growths of the lymph node tissue. It is associated with a number of malignancies, including Kaposi sarcoma, non-Hodgkin's and Hodgkins lymphoma, and POEMS syndrome. This report describes the case of a 38 year old gentleman, presenting with painless hematuria. Initial investigations, including flexible cystoscopy were unremarkable. However, subsequent imaging including CT Urogram and MR pelvis revealed multiple prevesical lesions. Histology obtained from excision biopsy revealed histological features consistent with Castleman's disease. In this report we discuss the nature, presentation and treatment modalities of this rare condition.

    The results of single contrast barium enema were retrospectively correlated with colonoscopically diagnosed colorectal disease in 54 patients (75 lesions). Altogether 66 lesions (88%) were correctly diagnosed. The sensitivity of barium enema for polyps was 81% (26/32). There were three perceptive errors and three polyps 5 mm or less in size were not demonstrated by barium enema. Twenty-nine cases of inflammatory disorders were all correctly diagnosed. One of 12 malignancies was missed by perceptive error. In two cases with vascular malformations the barium enema was normal. 4/9 (44%) of missed lesions were perceptive errors and could have been probably avoided by a second independent reading of films.

    An understanding of changes in pulmonology disease patterns observed at a general hospital before and after implantation of a population-based model of health care not only provides useful insight into the diseases treated but also aids adjustment of health care service organization. The aim of this study was to compare data collected after 1992 (when the new system was established) with records kept by the same pulmonology group in earlier years (1974-1986). Data after 1992 described patients attended in Health District 11 by the newly organized pneumologists. For the two periods the most common pneumological diagnoses were chronic air flow obstruction and chronic hypersecretory bronchitis. The most common non pneumological diagnoses were systemic arterial hypertension, obesity, diabetes, liver disease and hiatus hernia/gastroesophageal reflux. The prospective study covered a larger population and was closer to primary care, including as it did patients at clinics unattached to hospitals. In the earlier hospital-based experience the most common diagnoses were acute respiratory infection, chronic air flow obstruction and asthma, apart from those patients referred in whom no respiratory disease was found. With the organizational integration of hospital and health district pulmonology service, contact between patients and specialists has increased. Record systems have been established for a well-defined population to permit better forecasting at less cost and facilitate contact with primary care givers and epidemiological studies.

    The objective of this study is to evaluate a woman's risk perception for future cardiovascular disease (CVD) after being diagnosed with a hypertensive disorder of pregnancy. A prospective cohort of women diagnosed with a hypertensive disorder of pregnancy (HDP) was studied. Each woman completed two surveys, one prior to hospital discharge and one 2 weeks later, designed to assess knowledge of and risk perception for future CVD based on their recent diagnosis of a HDP. Rates of postpartum depression were also assessed. Of the 146 subjects included, 28% were diagnosed with preeclampsia with severe features, 52.1% with preeclampsia with mild features, and 19.9% had chronic hypertension. Women with severe features and those delivering preterm were more likely to report a perception of increased risk of both recurrent HDP in a future pregnancy (p = 0.004 and 0.005, respectively) and hypertension later in life (p = 0.01 and 0.03, respectively). Women delivering preterm were more likely to report an accurate perception of increased risk of myocardial infarction and stroke compared to those delivering at term (p = 0.006 and 0.002, respectively). Disease severity and preterm delivery were associated with a higher likelihood of the perception of an increased risk for both recurrent HDP and hypertension in the future. Only preterm delivery was associated with a higher risk perception for stroke and myocardial infarction. Interventions targeted at improved health awareness in women diagnosed with HDP are warranted.

  19. Using radiative signatures to diagnose the cause of warming during the 2013-2014 Californian drought

    California recently experienced among the worst droughts of the last century, with exceptional precipitation deficits and co-occurring record high temperatures. The dry conditions caused severe water shortages in one of the economically most important agricultural regions of the US. It has recently been hypothesized that anthropogenic warming is increasing the likelihood of such extreme droughts in California, or more specifically, that warmer temperatures from the enhanced greenhouse effect intensify drought conditions. However, separating the cause and effect is difficult because the dry conditions lead to a reduction in evaporative cooling that contributes to the warming. Here we investigate and compare the forcing of long-term greenhouse-induced warming with the short-term warming during the 2013-2014 Californian drought. We use the concept of radiative signatures to investigate the source of the radiative perturbation during the drought, relate the signatures to expected changes due to anthropogenic warming, and assess the cause of warming based on observed changes in the surface energy balance compared to the period 2001-2012. We found that the recent meteorological drought based on precipitation deficits was characterised by an increase in incoming shortwave radiation coupled with a decline in incoming longwave radiation, which contributed to record warm temperatures. In contrast, climate models project that anthropogenic warming is accompanied by little change in incoming shortwave but a large increase in incoming longwave radiation. The warming during the drought was associated with increased incoming shortwave radiation in combination with reduced evaporative cooling from water deficits, which enhanced surface temperatures and sensible heat transfer to the atmosphere. Our analyses demonstrate that radiative signatures are a powerful tool to differentiate the source of perturbations in the surface energy balance at monthly to seasonal time scales.

    Full Text Available Introduction. The association between celiac disease and eating disorders has been very rarely reported. This is the first report on celiac disease associated with bulimia in this part of Europe. Case report. An adult female patient with history of bulimia and one uncomplicated pregnancy was admitted to the Gastroenterology Department, due to long lasting dyspeptic symptoms, constipation, major weight loss and fatigue. After positive serological screening, the diagnosis of celiac disease was confirmed with histopathology examination of duodenal biopsy specimen. Conclusion. Complicated interactions between celiac disease and bulimia can make them difficult to diagnose and treat. It is important to consider the presence of celiac disease in patients with bulimia and gastrointestinal symptoms.

    Expert System is a system that seeks to adopt human knowledge to the computer, so that the computer can solve problems which are usually done by experts. The purpose of medical expert system is to support the diagnosis process of physicians. It considers facts and symptoms to provide diagnosis. This implies that a medical expert system uses knowledge about diseases and facts about the patients to suggest diagnosis. The aim of this research is to design an expert system application for diagnosing eye diseases using forward chaining method and to figure out user acceptance to this application through usability testing. Eye is selected because it is one of the five senses which is very sensitive and important. The scope of the work is extended to 16 types of eye diseases with 41 symptoms of the disease, arranged in 16 rules. The computer programming language employed was the PHP programming language and MySQL as the Relational Database Management System (RDBMS). The results obtained showed that the expert system was able to successfully diagnose eye diseases corresponding to the selected symptoms entered as query and the system evaluation through usability testing showed the expert system for diagnosis eye diseases had very good rate of usability, which includes learnability, efficiency, memorability, errors, and satisfaction so that the system can be received in the operational environment.

    Henning, Robert J; Johnson, Giffe T; Coyle, Jayme P; Harbison, Raymond D

    2017-07-01

    Acrolein is a highly reactive unsaturated aldehyde that is formed during the burning of gasoline and diesel fuels, cigarettes, woods and plastics. In addition, acrolein is generated during the cooking or frying of food with fats or oils. Acrolein is also used in the synthesis of many organic chemicals and as a biocide in agricultural and industrial water supply systems. The total emissions of acrolein in the United States from all sources are estimated to be 62,660 tons/year. Acrolein is classified by the Environmental Protection Agency as a high-priority air and water toxicant. Acrolein can exert toxic effects following inhalation, ingestion, and dermal exposures that are dose dependent. Cardiovascular tissues are particularly sensitive to the toxic effects of acrolein based primarily on in vitro and in vivo studies. Acrolein can generate free oxygen radical stress in the heart, decrease endothelial nitric oxide synthase phosphorylation and nitric oxide formation, form cytoplasmic and nuclear protein adducts with myocyte and vascular endothelial cell proteins and cause vasospasm. In this manner, chronic exposure to acrolein can cause myocyte dysfunction, myocyte necrosis and apoptosis and ultimately lead to cardiomyopathy and cardiac failure. Epidemiological studies of acrolein exposure and toxicity should be developed and treatment strategies devised that prevent or significantly limit acrolein cardiovascular toxicity.

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

  7. Experiences with the Haertel-Truebungstest at diagnosing injuries to spruce caused by atmospheric pollution

    Energy Technology Data Exchange (ETDEWEB)

    Pelz, E

    1958-01-01

    The Haertel-Truebungstest is based on the observation that spruce needles secrete more wax at the stomata in areas affected by atmospheric pollution than in areas without. The increased secretion of wax is taken for a symptom of injury caused by atmospheric pollution. The wax is extracted in boiling water and, after cooling down, the turbidity of the extract is measured quantitatively in a photometer. Investigations on spruce in Saxony and Thuringia confirm the tendency to increasing turbidity towards the source of smoke. A considerable dispersion of turbidity values however impairs the results of this method, so that a great number of samples must be used in order to find out a trend. The dispersion of turbidity values in spruce forests that are not directly influenced by atmospheric pollution substantially exceeds the dispersion of the +/- 1% of the turbidity value that was found by Haertel. As was stated by Haertel and Papesch, the dispersion of individual turbidity values grows with increasing doses of SO/sub 2/. In Saxony the individual smoke emissions so densely cover one another, that there are scarcely any areas without air pollution and, probably, a relation exists between this continuous influence of smoke and SO/sub 2/ and the dispersion of turbidity values. It may be, however, that the environmental factors have also a certain influence, as, on vast areas of Saxony, spruce is growing on sites that are not its natural habitat.

    Lips-Castro, Walter

    2015-01-01

    In the study of the causes of disease that have arisen during the development of humankind, one can distinguish three major perspectives: the natural, the supernatural, and the artificial. In this paper we distinguish the rational natural causes of disease from the irrational natural causes. Within the natural and rational causal approaches of disease, we can highlight the Egyptian theory of putrid intestinal materials called "wechdu", the humoral theory, the atomistic theory, the contagious theory, the cellular theory, the molecular (genetic) theory, and the ecogenetic theory. Regarding the irrational, esoteric, and mystic causal approaches to disease, we highlight the astrological, the alchemical, the iatrochemical, the iatromechanical, and others (irritability, solidism, brownism, and mesmerism).

    The utility of bronchoscopy for the diagnosis of pulmonary Mycobacterium avium-intracellulare complex (MAC) disease has been reported; however, which patients require bronchoscopy remains unclear. Our objective was to identify the characteristics of the patients in whom bronchoscopy is needed for the diagnosis of MAC disease. Fifty-four patients with pulmonary MAC disease were divided into two groups according to established diagnostic criteria: 39 patients were diagnosed by sputum culture and 15 patients were diagnosed by bronchial lavage culture. We analysed the differences in demographic and clinical characteristics as well as microbiological and radiological data between the two groups. There were no significant differences in age, sex, smoking status, MAC species, underlying diseases, or steroid use. Significantly more patients diagnosed by sputum culture than bronchial lavage culture had a positive sputum smear for acid-fast bacilli (79.5% vs. 0.0%, respectively; p disease, bronchiectasis, and cavities. However, more patients diagnosed by sputum culture than bronchial lavage culture had abnormalities in the left upper division (48.7% vs. 13.3%, respectively; p = 0.017) and higher numbers of affected lobes (4.3 ± 1.4 vs. 3.3 ± 1.6, respectively; p = 0.034). If patients suspected of having pulmonary MAC disease have a negative sputum smear, no symptoms, no abnormal findings in the left upper division, or fewer affected lobes on computed tomography, bronchoscopy might be needed for the diagnosis.

    Full Text Available Abstract Background Electronic health records are invaluable for medical research, but much information is stored as free text rather than in a coded form. For example, in the UK General Practice Research Database (GPRD, causes of death and test results are sometimes recorded only in free text. Free text can be difficult to use for research if it requires time-consuming manual review. Our aim was to develop an automated method for extracting coded information from free text in electronic patient records. Methods We reviewed the electronic patient records in GPRD of a random sample of 3310 patients who died in 2001, to identify the cause of death. We developed a computer program called the Freetext Matching Algorithm (FMA to map diagnoses in text to the Read Clinical Terminology. The program uses lookup tables of synonyms and phrase patterns to identify diagnoses, dates and selected test results. We tested it on two random samples of free text from GPRD (1000 texts associated with death in 2001, and 1000 general texts from cases and controls in a coronary artery disease study, comparing the output to the U.S. National Library of Medicine’s MetaMap program and the gold standard of manual review. Results Among 3310 patients registered in the GPRD who died in 2001, the cause of death was recorded in coded form in 38.1% of patients, and in the free text alone in 19.4%. On the 1000 texts associated with death, FMA coded 683 of the 735 positive diagnoses, with precision (positive predictive value 98.4% (95% confidence interval (CI 97.2, 99.2 and recall (sensitivity 92.9% (95% CI 90.8, 94.7. On the general sample, FMA detected 346 of the 447 positive diagnoses, with precision 91.5% (95% CI 88.3, 94.1 and recall 77.4% (95% CI 73.2, 81.2, which was similar to MetaMap. Conclusions We have developed an algorithm to extract coded information from free text in GP records with good precision. It may facilitate research using free text in electronic patient

    We herein report a case of 32-year-old woman who developed erythematous, indurated plaques, nodules on her lower back, hips and inguinal areas which had started after immunotherapy on the injection sites. She had a history of recurrent oral aphthous-like ulcers for 2 years and also had abdominal pain for 2 months. Colonoscopy revealed multiple aphthous ulcers on intestine. Diagnosis of lobular panniculitis was confirmed by histopathological finding of the skin biopsy and she was diagnosed as Behcet's disease. Eruptions due to mesotherapy accepted as hypersensitivity reaction. Before employing this technique, patients should be carefully examined for Behcet's pathognomonic clinical findings.

  19. Primary intestinal lymphangiectasia: A rare cause of diarrhea in adults diagnosed by capsule endoscopy and double balloon enteroscopy

    Directory of Open Access Journals (Sweden)

    Varun Gupta

    2014-01-01

    Full Text Available Primary intestinal lymphangiectasia (PIL or Waldmann′s disease is a rare protein-losing enteropathy presenting with diarrhea. The etiology and prevalence of PIL remain unknown. <200 cases have been reported in the literature so far. Diagnosis of intestinal lymphangiectasia is difficult as there are no serological or radiological tests available. Small bowel imaging modalities like capsule endoscopy and double balloon enteroscopy have increased the chances of diagnosis of PIL due to direct visualization of small bowel. Diagnosis is confirmed by characteristic histopathological finding, which includes dilated intestinal lymphatics with broadened villi of the small bowel. We report a case of a patient with chronic diarrhea who was extensively worked up before he was finally diagnosed to have PIL involving the small bowel by performing balloon enteroscopy-guided biopsy.

    A subset of patients reporting a diagnosis of Lyme disease can be described as having alternatively diagnosed chronic Lyme syndrome (ADCLS), in which diagnosis is based on laboratory results from a nonreference Lyme specialty laboratory using in-house criteria. Patients with ADCLS report symptoms similar to those reported by patients with chronic fatigue syndrome (CFS). We performed a case-control study comparing patients with ADCLS and CFS to each other and to both healthy controls and controls with systemic lupus erythematosus (SLE). Subjects completed a history, physical exam, screening laboratory tests, 7 functional scales, reference serology for Lyme disease using Centers for Disease Control and Prevention criteria, reference serology for other tick-associated pathogens, and cytokine expression studies. The study enrolled 13 patients with ADCLS (12 of whom were diagnosed by 1 alternative US laboratory), 25 patients with CFS, 25 matched healthy controls, and 11 SLE controls. Baseline clinical data and functional scales indicate significant disability among ADCLS and CFS patients and many important differences between these groups and controls, but no significant differences between each other. No ADCLS patient was confirmed as having positive Lyme serology by reference laboratory testing, and there was no difference in distribution of positive serology for other tick-transmitted pathogens or cytokine expression across the groups. In British Columbia, a setting with low Lyme disease incidence, ADCLS patients have a similar phenotype to that of CFS patients. Disagreement between alternative and reference laboratory Lyme testing results in this setting is most likely explained by false-positive results from the alternative laboratory. © The Author 2015.

    Conclusions: CKD-EPI and abbreviated MDRD formulas have a similar usefulness in GFR value estimation in patients with diagnosed chronic kidney disease. Lower eGFR values achieved using abbreviated MDRD formula and CKD-EPI equation in comparison with Bjornsson’s formula may result in an increased number of patients diagnosed with CKD.

    2016-01-01

    Paraprotein–related kidney disease represents a complex group of diseases caused by an abnormal paraprotein secreted by a clone of B cells. The disease manifestations range from tubulopathies, such as the Fanconi syndrome, to a spectrum of glomerular diseases that can present with varying degrees of proteinuria and renal dysfunction. Diagnosis of these diseases can be challenging because of the wide range of manifestations as well as the relatively common finding of a serum paraprotein, especially in elderly patients. Thus, renal biopsy along with detailed hematologic workup is essential to link the presence of the paraprotein to the associated renal disease. Recent advances in treatment with more effective and targeted chemotherapies, as well as stem cell transplantation, have improved the renal and overall prognosis for many of these disorders.

    2011-01-01

    Modern technologies have made the sequencing of personal genomes routine. They have revealed thousands of nonsynonymous (amino-acid altering) single nucleotide variants (nSNVs) of protein coding DNA per genome. What do these variants foretell about an individual’s predisposition to diseases? The experimental technologies required to carry out such evaluations at a genomic scale are not yet available. Fortunately, the process of natural selection has lent us an almost infinite set of tests in nature. During the long-term evolution, new mutations and existing variations have been evaluated for their biological consequences in countless species, and outcomes were readily revealed by multispecies genome comparisons. We review studies that have investigated evolutionary characteristics and in silico functional diagnoses of nSNVs found in thousands of disease-associated genes. We conclude that the patterns of long-term evolutionary conservation and permissible divergence are essential and instructive modalities for functional assessment of human genetic variations.

    2017-11-01

    Noninvasive engineering models are now being used for diagnosing and planning the treatment of cardiovascular disease. Techniques in computational modeling and additive manufacturing have matured concurrently, and results from simulations can inform and enable the design and optimization of therapeutic devices and treatment strategies. The emerging synergy between large-scale simulations and 3D printing is having a two-fold benefit: first, 3D printing can be used to validate the complex simulations, and second, the flow models can be used to improve treatment planning for cardiovascular disease. In this review, we summarize and discuss recent methods and findings for leveraging advances in both additive manufacturing and patient-specific computational modeling, with an emphasis on new directions in these fields and remaining open questions.

    To report the first case of prophylactic laser treatment to prevent blindness in a patient who was diagnosed with Norrie's disease by genetic testing with amniocentesis. Case report. A 2-year-old white boy with Norrie's disease. A 37-week gestational age male with a family history of Norrie's disease was born via Cesarean section after the mother had undergone prenatal amniocentesis fetal-genetic testing at 23 weeks of gestation. A C520T (nonsense) mutation was found in the Norrie's disease gene. After examination under anesthesia confirmed the diagnosis on the first day of life, laser photocoagulation was applied to the avascular retina bilaterally. The patient was followed closely by ophthalmology, pediatrics, and occupational therapy departments. Functional outcome, as documented by Teller visual acuity and formal occupational therapy testing, and anatomic outcome, as documented by Retcam photography and fluorescein angiography. Complete regression of extraretinal fibrovascular proliferation was observed 1 month after laser treatment. No retinal detachment had occurred to date at 24 months. Teller visual acuity at 23 months of life was 20/100 in both eyes. The patient's vision and developmental milestones were age appropriate. Pre-term genetic diagnosis with immediate laser treatment after birth may preserve vision in individuals affected with Norrie's disease. Copyright © 2010 American Academy of Ophthalmology.

    Adenine phosphoribosyltransferase (APRT) deficiency, cystinuria, Dent disease, familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) and primary hyperoxaluria (PH) are rare but important causes of severe kidney stone disease and/or chronic kidney disease in children. Recurrent kidney stone disease and nephrocalcinosis, particularly in pre-pubertal children, should alert the physician to the possibility of an inborn error of metabolism as the underlying cause. Unfortunately, the lack of recognition and knowledge of the five disorders has frequently resulted in an unacceptable delay in diagnosis and treatment, sometimes with grave consequences. A high index of suspicion coupled with early diagnosis may reduce or even prevent the serious long-term complications of these diseases. In this paper, we review the epidemiology, clinical features, diagnosis, treatment and outcome of patients with APRT deficiency, cystinuria, Dent disease, FHHNC and PH with emphasis on childhood manifestations.

    To evaluate the prevalence of mood and anxiety disorders in women with treated hyperthyroidism caused by Graves' disease and to compare them with the prevalence of such findings in women without past or present thyroid disease. Thirty inpatient women with treated hyperthyroidism and ophthalmopathy caused by Graves' disease and 45 women hospitalized for treatment of gynecologic disorders such as abnormal vaginal bleeding, benign tumors or infertility were evaluated for the prevalence of mood and anxiety diagnoses using a standard Mini-International Neuropsychiatric Interview and for mood and anxiety ratings using the Profile of Mood States (POMS). At the time of assessment, it was discovered that 14 of 30 women with treated hyperthyroidism caused by Graves' disease were still hyperthyroid, while 16 women were euthyroid. Significantly greater prevalence of social anxiety disorder, generalized anxiety disorder, major depression and total mood and anxiety disorders, as well as higher symptom scores on the POMS, was found in hyperthyroid women with Graves' disease in comparison with the control group. A prevalence of total anxiety disorder, as well as history of mania or hypomania and lifetime bipolar disorder, but not lifetime unipolar depression, was more frequent in both the euthyroid and the hyperthyroid subgroups of study women in comparison with the control group. These results confirm a high prevalence of mood and anxiety disorders in women with treated hyperthyroidism and ophthalmopathy caused by Graves' disease. Hyperthyroidism plays a major role in psychiatric morbidity in Graves' disease.

    Full Text Available Hydatid disease is an infrequent parasitic infestation caused by cestode, most commonly, Echinococcus granulosus. Bone involvement is distinctly uncommon. We would like to share our experience of a rare case of hydatid disease of femur in a 24-year-old male who presented with nonunion of subtrochanteric fracture. Histopathology showed typical lamellated wall and dagger-shaped hooklets. In view of its rarity, hydatid disease often remains an unsuspected infection of the bone.

    Full Text Available Kikuchi-Fujimoto disease (KFD, also known as histiocytic necrotizing lymphadenitis, is an uncommon clinical and pathologicalself-limited feature of benign prognosis that may mimic many other diseases diagnosed chiefly in youngadults. The etiology of the disease is unknown although several investigators postulate viral, parasitic and autoimmuneetiologies. The most common symptoms are cervical lymphadenopathy and fever. Diagnosis is usually rendered withexcisional biopsy of lymph nodes and through histopathological findings. Non-steroidal anti-inflammatory drugs areused for the treatment. In this report, two cases of KFD without any associated infectious and/or non-infectious conditionswere presented. J Microbiol Infect Dis 2012; 2(1: 21-25

  11. Value of the radiological study of the thorax for diagnosing left ventricular dysfunction in Chagas' disease

    Perez Amanda Arantes

    2003-01-01

    Full Text Available OBJECTIVE: To determine the value of the radiological study of the thorax for diagnosing left ventricular dilation and left ventricular systolic dysfunction in patients with Chagas' disease. METHODS: A cross-sectional study of 166 consecutive patients with Chagas' disease and no other associated diseases. The patients underwent cardiac assessment with chest radiography and Doppler echocardiography. Sensitivity, specificity, and positive and negative predictive values of chest radiography were calculated to detect left ventricular dysfunction and the accuracy of the cardiothoracic ratio in the diagnosis of left ventricular dysfunction with the area below the ROC curve. The cardiothoracic ratio was correlated with the left ventricular ejection fraction and the left ventricular diastolic diameter. RESULTS: The abnormal chest radiogram had a sensitivity of 50%, specificity of 80.5%, and positive and negative predictive values of 51.2% and 79.8%, respectively, in the diagnosis of left ventricular dysfunction. The cardiothoracic ratio showed a weak correlation with left ventricular ejection fraction (r=-0.23 and left ventricular diastolic diameter (r=0.30. The area calculated under the ROC curve was 0.734. CONCLUSION: The radiological study of the thorax is not an accurate indicator of left ventricular dysfunction; its use as a screening method to initially approach the patient with Chagas' disease should be reevaluated.

    Echocardiographic screening for rheumatic heart disease (RHD) can detect subclinical cases; however, adequate adherence to secondary antibiotic prophylaxis (SAP) is required to alter disease outcomes. We aimed to investigate the adherence to SAP among young people with RHD diagnosed through echocardiographic screening in Fiji and to investigate factors associated with adherence. Patients diagnosed with RHD through echocardiographic screening in Fiji from 2006 to 2014 were included. Dates of benzathine penicillin G injections were collected from 76 health clinics nationally from December 2011 to December 2014. Adherence was measured using the proportion of days covered (PDC). Multivariate logistic regression analysis was used to identify characteristics associated with any adherence (≥1 injection received) and adequate adherence (PDC ≥0.80). Of 494 patients, 268 (54%) were female and the median age was 14 years. Overall, 203 (41%) had no injections recorded and just 33 (7%) had adequate adherence. Multivariate logistic regression showed increasing age (OR 0.93 per year, 95% CI 0.87-0.99) and time since diagnosis ≥1.5 years (OR 0.53, 95% CI 0.37-0.79) to be inversely associated with any adherence. Non-iTaukei ethnicity (OR 2.58, 95%CI 1.04-6.33) and urban residence (OR 3.36, 95% CI 1.54-7.36) were associated with adequate adherence, whereas time since diagnosis ≥1.5 years (OR 0.38, 95%CI 0.17-0.83) was inversely associated with adequate adherence. Adherence to SAP after screening in Fiji is currently inadequate for individual patient protection or population disease control. Secondary prevention should be strengthened before further screening can be justified. © 2016 John Wiley & Sons Ltd.

    OBJECTIVE Despite its growing prevalence in China, the extent to which diabetes leads to excess cardiovascular disease (CVD) mortality and all-cause mortality is unclear. RESEARCH DESIGN AND METHODS We compared death rates and causes of death among 630 people with newly diagnosed diabetes (NDD) and 519 with normal glucose tolerance (NGT) who, in 1986, were identified as a result of screening 110,660 adults aged 25–74 years for diabetes in Da Qing, China. RESULTS During 23 years of follow-up, 338 (56.5%) participants with NDD and 100 (20.3%) with NGT died. CVD was the predominant cause of death in those with diabetes (47.5% in men and 49.7% in women), almost half of which was due to stroke (52.3% in men and 42.3% in women). The age-standardized incidence of all-cause death was three times as high in those with NDD as in those with NGT with incidences (per 1,000 person-years) of 36.9 (95% CI 31.5–42.3) vs. 13.3 (10.2–16.5) in men (P < 0.0001) and 27.1 (22.9–31.4) vs. 9.2 (7.8–10.6) in women (P < 0.0001). The incidence of CVD deaths in men and women with NDD (17.5 [13.8–21.2] vs. 13.5 [10.5–16.5]) did not differ significantly. Significantly higher death rates attributable to renal disease and infection were also found in the NDD group. CONCLUSIONS Diabetes is associated with a substantially increased risk of death in Chinese adults, especially from CVD, almost half of which is due to stroke. PMID:25887356

  14. Hyposplenism as a cause of pneumococcal meningoencephalitis in an adult patient with coeliac disease

    Directory of Open Access Journals (Sweden)

    Paolo Caraceni

    2013-03-01

    Full Text Available Introduction: Coeliac disease can be associated with hyposplenism and splenic atrophy, which may increase the patient’s risk for fatal infections caused by Streptococcus pneumoniae or Pneumococcus. It is general opinion that many more patients with coeliac disease have died from hyposplenism-related infections than those reported in literature. Case report: A 62-year-old woman with recently diagnosed coeliac disease was hospitalized with high fever, disorientation, and nuchal rigidity. Cerebral computed tomography was negative. Laboratory tests showed an elevated leukocyte count and very high levels of C reactive protein. The cerebrospinal fluid (CSF contained an increased number of mononuclear cells associated with a low glucose level and high protein concentrations. The CSF culture was positive for Streptococcus pneumoniae. Neurological conditions rapidly deteriorated with the onset of coma, and magnetic resonance imaging of the brain revealed initial signs of encephalitis extending above and below the tentorium. Abdominal ultrasonography disclosed splenic hypotrophy that raised the suspicion of hyposplenism. The diagnosis of hyposplenism was confirmed by demonstration of Howell-Jolly bodies in a peripheral blood smear. Discussion: This is the first reported case of pneumococcal meningoencephalitis caused by splenic hypofunction in a patient with coeliac disease. When coeliac disease is diagnosed with a marked delay in an elderly patient, spleen function should always be assessed. If impaired, the patient should undergo vaccination with pneumococcal conjugate vaccine to prevent pneumococcal infections.

    Full Text Available Background: Gastroesophageal reflux disease (GERD is associated with a number of comorbidities in pediatrics. However, its association with attention deficit hyperactivity disorder (ADHD has not been reported. The aim of the present study was to investigate the prevalence of ADHD in pediatric patients newly diagnosed with GERD. Materials and Methods: Sixty newly-diagnosed treatment naive GERD patients and sixty healthy controls aging between 5 to 12 years referring to the Children and Adolescent’s medical center, Tehran, Iran were recruited in a case-control study during the year 2015. Then patients were evaluated for ADHD by a psychiatrist according to the DSM-IV criteria. The revised Conners' Parent Rating Scale (CPRS-R was used for assessment of the symptoms of ADHD. To screen for psychiatry disorders other than ADHD, the Kiddie-Sads-Present and Lifetime Version (K-SADS-PL questionnaire was used. Logistic regression analysis was used for modeling the association between GERD and ADHD in the study sample. Results: The mean age of GERD patients was 5.77±2.27 and for non-GERD controls was 6.03±2.52 (P= 0.543. Thirty-three out of 60 (55% GERD patients and 37 out of 60(61.66% non-GERD controls were male (P: 0.579. Prevalence of ADHD was 33.60 (55% in GERD patients and 10.60 (16.66% in non-GERD (P

  16. Nuclear medicine methods used in diagnosing diseases of the gastrointestinal tract

    International Nuclear Information System (INIS)

    Kostadinova, I.

    2001-01-01

    Using physiologic tracer scintigraphy may give unique information on gastrointestinal (GI) motility and function, supplementing the findings of rather invasive methods. Conventional barium-contrast x-ray studies of the GI tract, computed tomography, ultrasonography and magnetic resonance imaging afford high resolution images of the GI anatomy, but have a serious shortcoming - hardly lending themselves to quantification. As shown by the results functional scintigraphy is a sensitive, quantitative and noninvasive procedure. The potential of nuclear medicine methods to diagnose successfully diseases of the salivary glands, esophagus, stomach and visualization of GI bleeding and hepatobiliary system are comprehensively discussed. The advantages and drawbacks of radionuclide techniques are outlined, and compared with other methods of visualization. (author)

  17. Diagnosing obesity by body mass index in chronic kidney disease: an explanation for the "obesity paradox?".

    Agarwal, Rajiv; Bills, Jennifer E; Light, Robert P

    2010-11-01

    Although obesity is associated with poor outcomes, among patients with chronic kidney disease (CKD), obesity is related to improved survival. These results may be related to poor diagnostic performance of body mass index (BMI) in assessing body fat content. Accordingly, among 77 patients with CKD and 20 controls, body fat percentage was estimated by air displacement plethysmography (ADP), skinfold thickness, and body impedance analysis. Defined by BMI ≥30 kg/m(2), the prevalence of obesity was 20% in controls and 65% in patients with CKD. Defined by ADP, the prevalence increased to 60% among controls and to 90% among patients with CKD. Although sensitivity and positive predictive value of BMI to diagnose obesity were 100%, specificity was 72%, but the negative predictive value was only 30%. BMI correctly classified adiposity in 75%. Regardless of the presence or absence of CKD, subclinical obesity (defined as BMI value of BMI for obesity, our study may provide an explanation of the "obesity paradox."

  18. Inorganic arsenic causes fatty liver and interacts with ethanol to cause alcoholic liver disease in zebrafish

    Full Text Available The rapid increase in fatty liver disease (FLD incidence is attributed largely to genetic and lifestyle factors; however, environmental toxicants are a frequently overlooked factor that can modify the effects of more common causes of FLD. Chronic exposure to inorganic arsenic (iAs is associated with liver disease in humans and animal models, but neither the mechanism of action nor the combinatorial interaction with other disease-causing factors has been fully investigated. Here, we examined the contribution of iAs to FLD using zebrafish and tested the interaction with ethanol to cause alcoholic liver disease (ALD. We report that zebrafish exposed to iAs throughout development developed specific phenotypes beginning at 4 days post-fertilization (dpf, including the development of FLD in over 50% of larvae by 5 dpf. Comparative transcriptomic analysis of livers from larvae exposed to either iAs or ethanol revealed the oxidative stress response and the unfolded protein response (UPR caused by endoplasmic reticulum (ER stress as common pathways in both these models of FLD, suggesting that they target similar cellular processes. This was confirmed by our finding that arsenic is synthetically lethal with both ethanol and a well-characterized ER-stress-inducing agent (tunicamycin, suggesting that these exposures work together through UPR activation to cause iAs toxicity. Most significantly, combined exposure to sub-toxic concentrations of iAs and ethanol potentiated the expression of UPR-associated genes, cooperated to induce FLD, reduced the expression of as3mt, which encodes an arsenic-metabolizing enzyme, and significantly increased the concentration of iAs in the liver. This demonstrates that iAs exposure is sufficient to cause FLD and that low doses of iAs can potentiate the effects of ethanol to cause liver disease.

    The rapid increase in fatty liver disease (FLD) incidence is attributed largely to genetic and lifestyle factors; however, environmental toxicants are a frequently overlooked factor that can modify the effects of more common causes of FLD. Chronic exposure to inorganic arsenic (iAs) is associated with liver disease in humans and animal models, but neither the mechanism of action nor the combinatorial interaction with other disease-causing factors has been fully investigated. Here, we examined the contribution of iAs to FLD using zebrafish and tested the interaction with ethanol to cause alcoholic liver disease (ALD). We report that zebrafish exposed to iAs throughout development developed specific phenotypes beginning at 4 days post-fertilization (dpf), including the development of FLD in over 50% of larvae by 5 dpf. Comparative transcriptomic analysis of livers from larvae exposed to either iAs or ethanol revealed the oxidative stress response and the unfolded protein response (UPR) caused by endoplasmic reticulum (ER) stress as common pathways in both these models of FLD, suggesting that they target similar cellular processes. This was confirmed by our finding that arsenic is synthetically lethal with both ethanol and a well-characterized ER-stress-inducing agent (tunicamycin), suggesting that these exposures work together through UPR activation to cause iAs toxicity. Most significantly, combined exposure to sub-toxic concentrations of iAs and ethanol potentiated the expression of UPR-associated genes, cooperated to induce FLD, reduced the expression of as3mt , which encodes an arsenic-metabolizing enzyme, and significantly increased the concentration of iAs in the liver. This demonstrates that iAs exposure is sufficient to cause FLD and that low doses of iAs can potentiate the effects of ethanol to cause liver disease.This article has an associated First Person interview with the first author of the paper. © 2018.

Chronic exposure to inorganic arsenic (iAs) is associated with liver disease in humans and animal models, but neither the mechanism of action nor the combinatorial interaction with other disease-causing factors has been fully investigated.

    Full Text Available The knowledge about correlation patterns between the fecal microbiota and inflammatory bowel diseases (IBD—comprising the two subforms Crohn's disease (CD and ulcerative colitis (UC—for newly diagnosed untreated children is limited. To address this knowledge gap, a selection of faecal specimens (CD, n=27 and UC, n=16 and non-IBD controls (n=30 children (age < 18 years was analysed utilising bacterial small subunit (SSU rRNA. We found, surprising age dependence for the fecal microbiota correlating to IBD. The most pronounced patterns were that E. coli was positively (R2=0.16, P=0.05 and Bacteroidetes, negatively (R2=0.15, P=0.05 correlated to age for CD patients. For UC, we found an apparent opposite age-related disease correlation for both Bacteroides and Escherichia. In addition, there was an overrepresentation of Haemophilus for the UC children. From our, results we propose a model where the aetiology of IBD is related to an on-going immunological development in children requiring different age-dependent bacterial stimuli. The impact of our findings could be a better age stratification for understanding and treating IBD in children.

    Optical Coherence tomography (OCT) images provide several indicators, e.g., the shape and the thickness of different retinal layers, which can be used for various clinical and non-clinical purposes. We propose an automated classification method to identify different ocular diseases, based on the local binary pattern features. The database consists of normal and diseased human eye SD-OCT images. We use a multiphase approach for building our classifier, including preprocessing, Meta learning, and active learning. Pre-processing is applied to the data to handle missing features from images and replace them with the mean or median of the corresponding feature. All the features are run through a Correlation-based Feature Subset Selection algorithm to detect the most informative features and omit the less informative ones. A Meta learning approach is applied to the data, in which a SVM and random forest are combined to obtain a more robust classifier. Active learning is also applied to strengthen our classifier around the decision boundary. The primary experimental results indicate that our method is able to differentiate between the normal and non-normal retina with an area under the ROC curve (AUC) of 98.6% and also to diagnose the three common retina-related diseases, i.e., Age-related Macular Degeneration, Diabetic Retinopathy, and Macular Hole, with an AUC of 100%, 95% and 83.8% respectively. These results indicate a better performance of the proposed method compared to most of the previous works in the literature.

    Full Text Available Retinal fundus images are widely used in diagnosing different types of eye diseases. The existing methods such as Feature Based Macular Edema Detection (FMED and Optimally Adjusted Morphological Operator (OAMO effectively detected the presence of exudation in fundus images and identified the true positive ratio of exudates detection, respectively. These mechanically detected exudates did not include more detailed feature selection technique to the system for detection of diabetic retinopathy. To categorize the exudates, Diabetic Fundus Image Recuperation (DFIR method based on sliding window approach is developed in this work to select the features of optic cup in digital retinal fundus images. The DFIR feature selection uses collection of sliding windows with varying range to obtain the features based on the histogram value using Group Sparsity Nonoverlapping Function. Using support vector model in the second phase, the DFIR method based on Spiral Basis Function effectively ranks the diabetic retinopathy disease level. The ranking of disease level on each candidate set provides a much promising result for developing practically automated and assisted diabetic retinopathy diagnosis system. Experimental work on digital fundus images using the DFIR method performs research on the factors such as sensitivity, ranking efficiency, and feature selection time.

    The overall published experience with pediatric type 1 Gaucher disease (GD1) has been based on ascertainment through clinical presentation of the disease. We describe the longitudinal follow-up in a presymptomatic pediatric cohort. The cohort includes children diagnosed with GD1, either prenatally or postnatally by molecular genetic testing, and followed for clinical care at our center from 1998 to 2016. All patients' parents were GBA mutation carriers identified through carrier screening programs. Longitudinal clinical, laboratory, and imaging data were obtained through chart review. Thirty-eight patients aged 1-18 years (mean at last visit 6.9 ± 4.1 years) were followed, including 32 p.N409S homozygotes and 6 p.N409S/p.R535H compound heterozygotes. At the last evaluation, a minority had hematological (5%), bone (15%), or linear growth (19%) issues. Only 12% had splenomegaly and 74% had moderate hepatomegaly. Chitotriosidase activity varied widely (6-5,640 nmol/hour/ml) and generally increased with age. Pediatric Gaucher severity scores (GSS) remained stable and within the mild-disease range for most (95%). Treatment for progressive disease during this period was recommended for four children. Most children with the p.N409S/p.N409S and p.N409S/p.R535H GD1 genotypes have minimal disease manifestations and progression during childhood and can be monitored using limited assessments. Those with other mutations may require additional monitoring. These data are valuable for newborn screening and counseling.Genet Med advance online publication 13 October 2016.

    To assess reductions of cerebral glucose metabolism in Parkinson's disease (PD) with 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET), and their associations with cognitive decline. FDG-PET was performed on a cohort of 79 patients with newly diagnosed PD (mean disease duration 8 months) and 20 unrelated controls. PD participants were scanned while on their usual dopaminergic medication. Cognitive testing was performed at baseline, and after 18 months using the Cognitive Drug Research (CDR) and Cambridge Neuropsychological Test Automated Battery (CANTAB) computerised batteries, the Mini-Mental State Examination (MMSE), and the Montreal Cognitive Assessment (MoCA). We used statistical parametric mapping (SPM V.12) software to compare groups and investigate voxelwise correlations between FDG metabolism and cognitive score at baseline. Linear regression was used to evaluate how levels of cortical FDG metabolism were predictive of subsequent cognitive decline rated with the MMSE and MoCA. PD participants showed reduced glucose metabolism in the occipital and inferior parietal lobes relative to controls. Low performance on memory-based tasks was associated with reduced FDG metabolism in posterior parietal and temporal regions, while attentional performance was associated with more frontal deficits. Baseline parietal to cerebellum FDG metabolism ratios predicted MMSE (β=0.38, p=0.001) and MoCA (β=0.3, p=0.002) at 18 months controlling for baseline score. Reductions in cortical FDG metabolism were present in newly diagnosed PD, and correlated with performance on neuropsychological tests. A reduced baseline parietal metabolism is associated with risk of cognitive decline and may represent a potential biomarker for this state and the development of PD dementia.

    2006-09-15

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

    BACKGROUND: Caring for a chronically ill spouse is stressful, but the health effects of caregiving are not fully understood. We studied the effect on mortality of being married to a person with Parkinson disease. METHODS: All patients in Denmark with a first-time hospitalization for Parkinson...... disease between 1986 and 2009 were identified, and each case was matched to five population controls. We further identified all spouses of those with Parkinson disease (n = 8,515) and also the spouses of controls (n = 43,432). All spouses were followed in nationwide registries until 2011. RESULTS: Among...... men, being married to a Parkinson disease patient was associated with a slightly higher risk of all-cause mortality (hazard ratio = 1.06 [95% confidence interval = 1.00-1.11]). Mortality was particularly high for death due to external causes (1.42 [1.09-1.84]) including suicide (1.89 [1...

    Chronic tobacco smoking is a major cause of preventable morbidity and mortality worldwide. In the lung, tobacco smoking increases the risk of lung cancer, and also causes chronic obstructive pulmonary disease (COPD), which encompasses both emphysema and chronic bronchitis. E-cigarettes (E-Cigs), or electronic nicotine delivery systems, were developed over a decade ago and are designed to deliver nicotine without combusting tobacco. Although tobacco smoking has declined since the 1950s, E-Cig ...

    Chronic diseases are major killers in the modern era. Physical inactivity is a primary cause of most chronic diseases. The initial third of the article considers: activity and prevention definitions; historical evidence showing physical inactivity is detrimental to health and normal organ functional capacities; cause vs. treatment; physical activity and inactivity mechanisms differ; gene-environment interaction [including aerobic training adaptations, personalized medicine, and co-twin physical activity]; and specificity of adaptations to type of training. Next, physical activity/exercise is examined as primary prevention against 35 chronic conditions [Accelerated biological aging/premature death, low cardiorespiratory fitness (VO2max), sarcopenia, metabolic syndrome, obesity, insulin resistance, prediabetes, type 2 diabetes, non-alcoholic fatty liver disease, coronary heart disease, peripheral artery disease, hypertension, stroke, congestive heart failure, endothelial dysfunction, arterial dyslipidemia, hemostasis, deep vein thrombosis, cognitive dysfunction, depression and anxiety, osteoporosis, osteoarthritis, balance, bone fracture/falls, rheumatoid arthritis, colon cancer, breast cancer, endometrial cancer, gestational diabetes, preeclampsia, polycystic ovary syndrome, erectile dysfunction, pain, diverticulitis, constipation, and gallbladder diseases]. The article ends with consideration of deterioration of risk factors in longer-term sedentary groups; clinical consequences of inactive childhood/adolescence; and public policy. In summary, the body rapidly maladapts to insufficient physical activity, and if continued, results in substantial decreases in both total and quality years of life. Taken together, conclusive evidence exists that physical inactivity is one important cause of most chronic diseases. In addition, physical activity primarily prevents, or delays, chronic diseases, implying that chronic disease need not be an inevitable outcome during life

    Full Text Available Chronic kidney disease (CKD is a growing problem in Nigeria, presenting challenges to the nation’s health and economy. This study evaluates the accessibility to healthcare in Edo State of CKD patients diagnosed between 2006 and 2009. Using cost analysis techniques within a geographical information system, an estimated travel time to the hospital was used to examine the spatial accessibility of diagnosed patients to available CKD healthcare in the state. The results from the study indicated that although there was an annual rise in the number of diagnosed cases, there were no significant changes in the proportion of patients that were diagnosed at the last stage of CKD. However, there were indications that the travel time to the hospital for CKD treatment might be a contributing factor to the number of diagnosed CKD cases. This implies that the current structure for CKD management within the state might not be adequate.

    The aim of the study was to evaluate the rate of relapse as well as disease-free, overall, and disease-specific survival in women with borderline ovarian tumour (BOT). Furthermore, the study aims to identify the clinical parameters correlated to relapse. National clinical data of women diagnosed with BOT from January 2005 to January 2013 constituted the basis for our study population. The prognostic influence of clinical variables was evaluated using univariate and multivariate analyses. A total of 1143 women were eligible for analysis, with 87.9% in FIGO stage I and 12.1% in FIGO stages II-IV. Relapse of BOT was detected in 3.7%, hereof 40.5% with malignant transformation. The five-year disease-free survival was 97.6% in FIGO stage I and 87.3% in FIGO stages II-IV. Younger age, laparoscopic surgical approach, fertility sparing surgery, FIGO stages II-IV, bilateral tumour presence, serous histology, implants and microinvasion of the tumour were significantly associated with relapse in univariate analyses. The overall five-year survival rate was 92.2% in FIGO stage I and 89.0% in FIGO stages II-IV. Out of 77 deaths in total, only seven women died from BOT. A general favourable prognosis in women with BOT was confirmed in our study. Our findings indicate that systematic, long-term follow-up does not seem necessary in women treated for FIGO stage IA BOT with no residual disease or microinvasion. Copyright © 2016 Elsevier Inc.

    It remains unclear whether transbronchial lung biopsy (TBLB) is useful for diagnosing Mycobacterium avium complex (MAC) lung disease. Thirty-eight consecutive patients with MAC lung disease, who were evaluated with TBLB tissue culture between June 2006 and May 2010, were included. Bronchial washing (BW) and histopathological evaluation were performed in all patients. The positivity rates of BW and TBLB tissue culture, and typical histopathological findings for MAC disease were investigated. Furthermore, all patients were divided into two groups according to the presence of intrabronchial purulent or mucopurulent secretion and the clinical, bacteriological and pathological characteristics were compared between the two groups. The positive culture rates of BW and TBLB specimens for MAC were 100% (38 patients) and 28.9% (11 patients). BW materials were much more sensitive for culture positivity than TBLB specimens (P present in the TBLB specimens of only 11 patients (28.9%). Intrabronchial secretion was identified in 15 patients (39.5%, secretion-positive group) and absent in 23 patients (60.5%, secretion-negative group). Typical histopathological findings for MAC disease were more common in the secretion-positive group than in the secretion-negative group (53.3% vs 13.0%, P = 0.01), although the radiological classification and smear positivity of BW were not different between the two groups. TBLB for pathological and bacterial investigations would provide only a limited value for MAC diagnosis. Moreover, the presence of intrabronchial secretion may be an important manifestation of ongoing airway damage, which would require early treatment. © 2016 John Wiley & Sons Ltd.

    Anthracnose disease is one of the major economic constraints to chilli production worldwide, especially in tropical and subtropical regions. Accurate taxonomic information is necessary for effective disease control management. In the Colletotrichum patho-system, different Colletotrichum species can be associated with anthracnose of the same host. Little information is known concerning the interactions of the species associated with the chilli anthracnose although several Colletotrichum species have been reported as causal agents of chilli anthracnose disease worldwide. The ambiguous taxonomic status of Colletotrichum species has resulted in inaccurate identification which may cause practical problems in plant breeding and disease management. Although the management and control of anthracnose disease are still being extensively researched, commercial cultivars of Capsicum annuum that are resistant to the pathogens that cause chilli anthracnose have not yet been developed. This paper reviews the causal agents of chilli anthracnose, the disease cycle, conventional methods in identification of the pathogen and molecular approaches that have been used for the identification of Colletotrichum species. Pathogenetic variation and population structure of the causal agents of chilli anthracnose along with the current taxonomic status of Colletotrichum species are discussed. Future developments leading to the disease management strategies are suggested. PMID:18837103

    The long-term prognosis of patients with Kawasaki disease (KD) complicated by coronary artery aneurysm (CAA) is unclear. The aim of this study was to evaluate the complications of KD with CAAs. We retrospectively analyzed the clinical data and complications of 38 KD patients with CAAs who were treated and underwent regular follow-up with echocardiography between January 1989 and May 2013. During a period of 29 days to 19 years after disease onset, complications seen included coronary stenosis and occlusion (six patients), thrombosis (17 patients), myocardial infarction (six patients), and calcification of CAAs (seven patients). Rupture of giant CAAs occurred in two patients and caused sudden death in one of these patients at 29 days and in the other patient at 5 months after disease onset. A total of seven deaths occurred, with five deaths caused by myocardial infarction. Three of these had undiagnosed incomplete KD or had not received regular treatment, while two experienced sudden death after several asymptomatic myocardial infarctions. Cardiac complications of KD with CAAs include thrombosis, coronary stenosis, myocardial infarction, sudden death, and calcification. Although rare, rupture of giant CAAs is fatal and might occur earlier after the onset of disease. Mortality occurred primarily in the earlier cases when anticoagulant therapy was insufficient and in patients who did not receive regular treatment. Echocardiography can provide reliable information for assessing the progression and prognosis of this condition. © 2015, Wiley Periodicals, Inc.

    Determination of overweight and obesity prevalence in children with inflammatory bowel disease (IBD) at the time of diagnosis. This was a multicenter retrospective study. The study group consisted of children with new cases of IBD diagnosed in 2005-2013 according to the Porto criteria. Hospital admission records were reviewed for demographic and clinical characteristics. BMI-for-age and gender percentile charts were used to define overweight as ≥85th BMI percentile and obesity as ≥95th BMI percentile. 675 patients were evaluated: 368 with Crohn's disease (CD) and 307 with ulcerative colitis (UC). Of these, 54.8% were boys and 45.2% were girls. There were no statistically significant differences in age, weight, height and disease activity between the CD and UC patients. The UC patients had higher BMI values than the CD patients. The prevalence of overweight and obesity was higher in the UC than the CD patients (4.89% CI95 2.76-7.93 vs. 2.45% CI95 1.12-4.59 and 8.47% CI95 5.61-12.16 vs. 1.9% CI95 0.77-3.88, respectively); the differences were statistically significant (-2.44% CI95 -5.45 to 0.49 and -6.57% CI95 -10 to -3.1, respectively). The risk of overweight/obesity was 3.5 times higher for patients with UC (OR=0.272, CI95 0.14-0.49, p=0.0004). The prevalence of overweight and obesity in newly diagnosed children with IBD was 8.4% and was higher in patients with UC than in patients with CD. The results of this study have shown that not only malnourished children may suffer from IBD but also children who are overweight or obese at the time of diagnosis.

    Between 1 January 2010 and 31 December 2016, a total of 14 U.S. and international military personnel in training at Joint Base San Antonio-Lackland, TX, were hospitalized due to suspected pulmonary tuberculosis (TB); of these, five personnel were diagnosed with active TB disease. Only one TB case had pulmonary symptoms, but these symptoms were not suggestive of TB. The incidence rate in the training population was 1.89 per 100,000 population (95% CI: 0.81, 4.42), with a higher rate when restricted to international military students attending the Defense Language Institute English Language Center. No instances of TB transmission were identified. The variety of atypical presentations and their resulting diagnostic and public health challenges prompted this retrospective review of all hospitalized cases. This case series highlights both the importance of a high index of clinical suspicion when TB is being considered in close congregate settings as well as the risk of overreliance on acid-fast bacilli staining and nucleic acid amplification testing for ruling out active pulmonary disease in young, otherwise healthy trainees. Practical solutions are suggested.

    Full Text Available Hypertrophic cardiomyopathy is the most common inherited disease of the myocardium. The causes of the disease are heterogeneous; its primary form results from mutations in the genes encoding cardiac sarcomeric proteins; its secondary (metabolic and syndromic forms develop due to mutations in the genes encoding non-sarcomeric proteins. Glycogenosis is the most common cause of the metabolic ones of hypertrophic cardiomyopathy. Danon’s disease (lysosome-associated membrane protein 2 (LAMP2-cardiomyopathy is a form of glycogenosis and it is characterized by a typical triad: hypertrophic cardiomyopathy, mental retardation, and skeletal myopathy. The disease occurs with mutations in the LAMP2 gene; X-linked dominant inheritance. LAMP2-cardiomyopathy does not virtually differ in its clinical manifestations from the severe form of hypertrophic cardiomyopathy, which results from mutations in the sarcomeric protein genes. The disease is characterized by a poor progressive course with the high probability of causing sudden death or with the progression of severe heart failure. Implantation of a cardioverter defibrillator is a main method to prevent sudden cardiac death.

    A retrospective review of admission preductal oxygen saturations of neonates with antenatally diagnosed critical congenital heart disease (CCHD) was performed to investigate the differences in newborn pulse oximetry (Pulsox) by specific CCHD diagnosis. Saturations were recorded at median of  34 weeks and birth weight > 1.8 kg. A statistically significant increase in the proportion with low admission saturations was seen using ≤ 95% saturation threshold (72% (95% CI 66-78)) compared to ≤ 92% (52% (95% CI 46-59)) and ≤ 90% (46% (95% CI 39-52)). Sub-group analysis found the proportion of neonates with low saturations varied according to the specific CCHD diagnosis with only 20-42% of neonates with aortic stenosis, coarctation of the aorta and pulmonary stenosis having saturations ≤ 95%. The proportion of neonates with low admission oxygen saturation varied by CCHD diagnosis with those without critically reduced pulmonary blood flow not having low admission saturations, in general, even using the ≤ 95% threshold which had the highest proportions of abnormal saturations. This data may assist developing Pulsox screening policies. What is Known: • The addition of pulse oximetry (Pulsox) screening to the routine newborn examination increases the sensitivity of CCHD detection. Pulsox screening is also highly specific for CCHD in asymptomatic neonates, with low false-positive rates. • Early diagnosis of CCHD improves patient outcomes in relation to both morbidity and mortality. What is New: • The proportion of affected infants with an abnormal Pulsox result varies by CCHD diagnosis and screening threshold. In our study using the ≤ 95% threshold gave the highest proportion of neonates with abnormal saturations at admission. • In general, Pulsox yield of abnormal results is low for CCHD diagnoses not associated with critically reduced pulmonary blood flow; however, increasing the Pulsox threshold increased the proportion of infants with an

    Vascular pathologies are rare causes of an acute abdomen. If the cause is a vascular disease a rapid diagnosis is desired as vascular pathologies are associated with high mortality. A differentiation must be made between arterial and venous diseases. An occlusion of the superior mesenteric artery is the most common reason for acute mesenteric ischemia but intra-abdominal arterial bleeding is also of great importance. Venous pathologies include thrombotic occlusion of the portal vein, the mesenteric vein and the vena cava. Multi-detector computed tomography (MDCT) is predestined for the diagnostics of vascular diseases of the abdomen. Using multiphasic contrast protocols enables reliable imaging of the arterial and venous vessel tree and detection of disorders with high sensitivity and specificity. Although conventional angiography has been almost completely replaced by MDCT as a diagnostic tool, it is still of high importance for minimally invasive interventions, for example in the management of gastrointestinal bleeding.

    Full Text Available BACKGROUND Disturbances in lipid metabolism, which occur during hypothyroidism lead to the formation of gallstones. This study aims to evaluate the thyroid function pattern in patients with gallstones. The aim of this study was to investigate the association between hypothyroidism and gallstone disease. MATERIALS AND METHODS 200 patients admitted as inpatients for management of gallstone disease in Department of General Surgery, GRH, Madurai, between September 2014 to August 2015 were evaluated with details of cases, full history, clinical examination, symptoms and signs of hypothyroidism (loss of appetite, gaining weight, tiredness, constipation, cold intolerance, menstrual disturbances, bradycardia, presence or absence of goiter, etc. and investigations (USG abdomen, USG neck, thyroid function test (T3, T4, TSH. Patients are divided according to history, clinical examination, USG neck and lab estimation of T3, T4 and TSH. 1. Subclinical Hypothyroidism: Symptom free patient with TSH concentration above upper limit of normal range and T3/T4 or both decrease below normal limit. 2. Clinical Hypothyroidism: In which, there are symptoms of hypothyroidism with TSH level above the upper limit and T3/T4 or both decrease below normal limit. 3. Euthyroid Group: Where clinical and lab tests are within normal range (all these groups may present with or without goiter. RESULTS This study included 200 gallstone patients who were studied prospectively over a period of 1 year from September 2014 to August 2015. Among them, 18 patients had subclinical hypothyroidism and 6 patients had clinical hypothyroidism. A total of 12% of gallstone patients were diagnosed to have hypothyroidism showing that there is association of hypothyroidism with gallstone disease. CONCLUSION Thyroid dysfunction is more common among patients with gallstones and it maybe a risk factor for biliary stone formation. This may be attributed to the absence of the pro-relaxing effects of

    Rheumatic heart disease (RHD) remains the leading acquired heart disease in the young worldwide. We aimed at assessing outcomes and influencing factors in the contemporary era. Hospital-based cohort in a high-income island nation where RHD remains endemic and the population is captive. All patients admitted with newly diagnosed RHD according to World Heart Federation echocardiographic criteria were enrolled (2005-2013). The incidence of major cardiovascular events (MACEs) including heart failure, peripheral embolism, stroke, heart valve intervention and cardiovascular death was calculated, and their determinants identified. Of the 396 patients, 43.9% were male with median age 18 years (IQR 10-40)). 127 (32.1%) patients presented with mild, 131 (33.1%) with moderate and 138 (34.8%) with severe heart valve disease. 205 (51.8%) had features of acute rheumatic fever. 106 (26.8%) presented with at least one MACE. Among the remaining 290 patients, after a median follow-up period of 4.08 (95% CI 1.84 to 6.84) years, 7 patients (2.4%) died and 62 (21.4%) had a first MACE. The annual incidence of first MACE and of heart failure were 59.05‰ (95% CI 44.35 to 73.75) and 29.06‰ (95% CI 19.29 to 38.82), respectively. The severity of RHD at diagnosis (moderate vs mild HR 3.39 (0.95 to 12.12); severe vs mild RHD HR 10.81 (3.11 to 37.62), pdisease and no secondary prophylaxis.

    Gastroesophageal reflux disease (GERD) is a gastrointestinal disorder in which stomach acids are chronically regurgitated into the esophagus and oral cavity. Continual exposure of the teeth to these acids can cause severe tooth wear. Dentists are often the first healthcare professionals to diagnose dental erosion in patients with GERD. This article presents a case report of a 27-year-old male smoker with tooth wear and dentin sensitivity caused by GERD associated with bruxism. After diagnosis...

    Standard neuroimaging fails in defining the anatomy of the substantia nigra and has a marginal role in the diagnosis of Parkinson disease. Recently 7T MR target imaging of the substantia nigra has been useful in diagnosing Parkinson disease. We performed a comparative study to evaluate whether susceptibility-weighted angiography can diagnose Parkinson disease with a 3T scanner. Fourteen patients with Parkinson disease and 13 healthy subjects underwent MR imaging examination at 3T and 7T by using susceptibility-weighted angiography. Two expert blinded observers and 1 neuroradiology fellow evaluated the 3T and 7T images of the sample to identify substantia nigra abnormalities indicative of Parkinson disease. Diagnostic accuracy and intra- and interobserver agreement were calculated separately for 3T and 7T acquisitions. Susceptibility-weighted angiography 7T MR imaging can diagnose Parkinson disease with a mean sensitivity of 93%, specificity of 100%, and diagnostic accuracy of 96%. 3T MR imaging diagnosed Parkinson disease with a mean sensitivity of 79%, specificity of 94%, and diagnostic accuracy of 86%. Intraobserver and interobserver agreement was excellent at 7T. At 3T, intraobserver agreement was excellent for experts, and interobserver agreement ranged between good and excellent. The less expert reader obtained a diagnostic accuracy of 89% at 3T. Susceptibility-weighted angiography images obtained at 3T and 7T differentiate controls from patients with Parkinson disease with a higher diagnostic accuracy at 7T. The capability of 3T in diagnosing Parkinson disease might encourage its use in clinical practice. The use of the more accurate 7T should be supported by a dedicated cost-effectiveness study. © 2015 by American Journal of Neuroradiology.

  13. Genetics of Autosomal Recessive Polycystic Kidney Disease and Its Differential Diagnoses

    2018-02-01

    Full Text Available Autosomal recessive polycystic kidney disease (ARPKD is a hepatorenal fibrocystic disorder that is characterized by enlarged kidneys with progressive loss of renal function and biliary duct dilatation and congenital hepatic fibrosis that leads to portal hypertension in some patients. Mutations in the PKHD1 gene are the primary cause of ARPKD; however, the disease is genetically not as homogeneous as long thought and mutations in several other cystogenes can phenocopy ARPKD. The family history usually is negative, both for recessive, but also often for dominant disease genes due to de novo arisen mutations or recessive inheritance of variants in genes that usually follow dominant patterns such as the main ADPKD genes PKD1 and PKD2. Considerable progress has been made in the understanding of polycystic kidney disease (PKD. A reduced dosage of disease proteins leads to the disruption of signaling pathways underlying key mechanisms involved in cellular homeostasis, which may help to explain the accelerated and severe clinical progression of disease course in some PKD patients. A comprehensive knowledge of disease-causing genes is essential for counseling and to avoid genetic misdiagnosis, which is particularly important in the prenatal setting (e.g., preimplantation genetic diagnosis/PGD. For ARPKD, there is a strong demand for early and reliable prenatal diagnosis, which is only feasible by molecular genetic analysis. A clear genetic diagnosis is helpful for many families and improves the clinical management of patients. Unnecessary and invasive measures can be avoided and renal and extrarenal comorbidities early be detected in the clinical course. The increasing number of genes that have to be considered benefit from the advances of next-generation sequencing (NGS which allows simultaneous analysis of a large group of genes in a single test at relatively low cost and has become the mainstay for genetic diagnosis.

    The United States and other developed countries experienced enormous improvements in population health during the 20th century. In the context of this dramatic positive change, health disparities by race and socioeconomic status emerged for several potent killers. Any explanation for current health disparities must take these changing patterns into account. Any explanation that ignores large improvements in population health and fails to account for the emergence of disparities for specific diseases is an inadequate explanation of current disparities. We argue that genetic explanations and some prominent social causation explanations are incompatible with these facts. We propose that the theory of "fundamental causes" can account for both vast improvements in population health and the creation of large socioeconomic and racial disparities in mortality for specific causes of death over time. Specifically, we argue that it is our enormously expanded capacity to control disease and death in combination with existing social and economic inequalities that create health disparities by race and socioeconomic status: When we develop the ability to control disease and death, the benefits of this new-found ability are distributed according to resources of knowledge, money, power, prestige, and beneficial social connections. We present data on changing mortality patterns by race and socioeconomic status for two types of diseases: those for which our capacity to prevent death has increased significantly and those for which we remain largely unable to prevent death. Time trends in mortality patterns are consistent with the fundamental cause explanation.

    Helicobacter pylori (H. pylori) is the main cause of chronic gastritis and a major risk factor for gastric cancer. This pathogen has also been considered a potential trigger of gastric autoimmunity, and in particular of autoimmune gastritis. However, a considerable number of reports have attempted to link H. pylori infection with the development of extra-gastrointestinal autoimmune disorders, affecting organs not immediately relevant to the stomach. This review discusses the current evidence in support or against the role of H. pylori as a potential trigger of autoimmune rheumatic and skin diseases, as well as organ specific autoimmune diseases. We discuss epidemiological, serological, immunological and experimental evidence associating this pathogen with autoimmune diseases. Although over one hundred autoimmune diseases have been investigated in relation to H. pylori, we discuss a select number of papers with a larger literature base, and include Sjögrens syndrome, rheumatoid arthritis, systemic lupus erythematosus, vasculitides, autoimmune skin conditions, idiopathic thrombocytopenic purpura, autoimmune thyroid disease, multiple sclerosis, neuromyelitis optica and autoimmune liver diseases. Specific mention is given to those studies reporting an association of anti-H. pylori antibodies with the presence of autoimmune disease-specific clinical parameters, as well as those failing to find such associations. We also provide helpful hints for future research. PMID:24574735

Occurrence of retained fetal membrane tended to and was associated with reduced prepartum (444.3 ± 11.0 vs. 466.5 ± 4.3 arbitrary unit) and postpartum (488.2 ± 14.5 vs. 538.8 ± 5.7 arbitrary unit) activity, respectively. Cows diagnosed with metritis had reduced postpartum DRT (415.9 ± 10.1 vs. 441.0 ± 5.2 min/d) and activity (512.5 ± 11.5 vs. 539.2 ± 6.0 arbitrary unit). Postpartum activity was reduced among cows that were diagnosed with subclinical ketosis (502.20 ± 16.5 vs. 536.6 ± 6.2 arbitrary unit). Although differences in DRT and activity between populations of cows that developed periparturient diseases and healthy cows were observed, further experiments are necessary to determine how DRT and activity data may be used to precociously diagnose individuals that will develop such periparturient diseases.

  17. New technologies to diagnose and monitor infectious diseases of livestock: Challenges for sub-Saharan Africa

    Directory of Open Access Journals (Sweden)

    Donald P. King

    2012-06-01

    Effective control of infectious diseases is reliant upon accurate diagnosis of clinical cases using laboratory tests, together with an understanding of factors that impact upon the epidemiology of the infectious agent. A wide range of new diagnostic tools and nucleotide sequencing methods are used by international reference laboratories to detect and characterise the agents causing outbreaks of infectious diseases. In the past, high costs (initial capital expenses, as well as day-to-day maintenance and running costs and complexity of the protocols used to perform some of these tests have limited the use of these methods in smaller laboratories. However, simpler and more cost-effective formats are now being developed that offer the prospect that these technologies will be even more widely deployed into laboratories particularly those in developing regions of the world such as sub-Saharan Africa.

    The minimum basic dataset is the largest available hospital care administrative database that is used in clinical studies and hospital management in association with diagnosis-related groups (DRGs). In 2011, the quality of the national MBDS in hospital discharges was audited, in order to assess its reliability. This paper presents a sub-analysis of the results from that analysis which are referred to cerebrovascular disease (CVD). Using all discharge reports from the Spanish MBDS in 2009, a representative sample was obtained by stratified sampling and 11 209 records were evaluated. Outcome indicators were obtained to measure any differences observed between the national MBDS being evaluated and the hospital's original MBDS. Analysis of codes for CVD as a primary diagnosis was performed for ICD-9-CM diagnostic categories 430 through 438. We evaluated error rates in the selection and classification of main diagnoses, as well as in DRG assignment. There were 397 discharges of cases of CVD which included 21 different DRGs. Diagnostic coding showed a concordance rate of 81.87%; the selection error rate was 2.26% and the classification error rate was 15.87%. The error rate in the DRG was 16.12% and associated with the greatest impact on the mortality risk level. While the errors we observed must be taken into account, data suggest that the quality of the MBDS for CVD is sufficient to ensure delivery of valid information. The hospital discharge registry serves as a valuable tool for use in studies of this disease. Copyright © 2014 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U.

    Recent studies have shown that patients with inflammatory bowel disease (IBD) are less likely to be infected with Helicobacter pylori compared with non-IBD patients. We aimed to study the prevalence of H. pylori-positive and H. pylori-negative gastritis in newly diagnosed children with IBD in comparison to those with non-IBD in Greece. All children who underwent first esophagogastroduodenal endoscopy between 2002 and 2011 were retrospectively included. Four groups were studied: patients with Crohn's disease (CD), ulcerative colitis (UC), IBD unclassified (IBDU), and non-IBD individuals (non-IBD). Helicobacter pylori infection was defined by positive culture or by positive histology and CLO test. Those children with negative or not available culture and only one positive test (histology or CLO) were further evaluated by urea breath test, and the positives were also included in the infected group. We studied 159 patients with IBD (66 CD, 34 UC, and 59 IBDU) and 1209 patients in non-IBD individuals. Helicobacter pylori gastritis was less frequent in the IBD group (3.8% vs 13.2% in the control group, p gastritis were 3.3 times more likely to belong in the IBD group compared with H. pylori-positive patients (p = .006). Occurrence of H. pylori gastritis is less frequent in children with IBD compared with controls. Our study confirms an inverse association between H. pylori and IBD. Future studies are needed to distinguish between a true protective role of H. pylori and a confounding effect due to previous antibiotic use in children with IBD. © 2014 John Wiley & Sons Ltd.

    Full Text Available Abstract Background Staphylococcus aureus is one of the most common causes of intramammary infections in dairy cows at dry off. Reliable identification is important for disease management on herd level and for antimicrobial treatment of infected animals. Our objective was to evaluate the test characteristics of PathoProof ™ Mastitis PCR Assay and bacteriological culture (BC in diagnosing bovine intramammary infections caused by S. aureus at dry off at different PCR cycle threshold (Ct-value cut-offs. Methods Sterile quarter samples and non-sterile composite samples from 140 animals in seven herds were collected in connection with the dairy herd improvement (DHI milk recording. All quarter samples were analyzed using BC whereas all composite samples were analyzed with PathoProof ™ Mastitis PCR Assay. Latent class analysis was used to estimate test properties for PCR and BC in the absence of a perfect reference test. The population was divided into two geographically divided subpopulations and the Hui-Walter 2-test 2-populations model applied to estimate Se, Sp for the two tests, and prevalence for the two subpopulations. Results The Se for PCR increased with increasing Ct-value cut-off, accompanied by a small decrease in Sp. For BC the Se decreased and Sp increased with increasing Ct-value cut-off. Most optimal test estimates for the real-time PCR assay were at a Ct-value cut-off of 37; 0.93 [95% posterior probability interval (PPI 0.60-0.99] for Se and 0.95 [95% PPI 0.95-0.99] for Sp. At the same Ct-value cut-off, Se and Sp for BC were 0.83 [95% PPI 0.66-0.99] and 0.97 [95% PPI 0.91-0.99] respectively. Depending on the chosen PCR Ct-value cut-off, the prevalence in the subpopulations varied; the prevalence increased with increasing PCR Ct-value cut-offs. Conclusion Neither BC nor real-time PCR is a perfect test in detecting IMI in dairy cows at dry off. The changes in sensitivity and prevalence at different Ct-value cut-offs for both PCR and

    Stricturing and penetrating complications account for substantial morbidity and health-care costs in paediatric and adult onset Crohn's disease. Validated models to predict risk for complications are not available, and the effect of treatment on risk is unknown. We did a prospective inception cohort study of paediatric patients with newly diagnosed Crohn's disease at 28 sites in the USA and Canada. Genotypes, antimicrobial serologies, ileal gene expression, and ileal, rectal, and faecal microbiota were assessed. A competing-risk model for disease complications was derived and validated in independent groups. Propensity-score matching tested the effect of anti-tumour necrosis factor α (TNFα) therapy exposure within 90 days of diagnosis on complication risk. Between Nov 1, 2008, and June 30, 2012, we enrolled 913 patients, 78 (9%) of whom experienced Crohn's disease complications. The validated competing-risk model included age, race, disease location, and antimicrobial serologies and provided a sensitivity of 66% (95% CI 51-82) and specificity of 63% (55-71), with a negative predictive value of 95% (94-97). Patients who received early anti-TNFα therapy were less likely to have penetrating complications (hazard ratio [HR] 0·30, 95% CI 0·10-0·89; p=0·0296) but not stricturing complication (1·13, 0·51-2·51; 0·76) than were those who did not receive early anti-TNFα therapy. Ruminococcus was implicated in stricturing complications and Veillonella in penetrating complications. Ileal genes controlling extracellular matrix production were upregulated at diagnosis, and this gene signature was associated with stricturing in the risk model (HR 1·70, 95% CI 1·12-2·57; p=0·0120). When this gene signature was included, the model's specificity improved to 71%. Our findings support the usefulness of risk stratification of paediatric patients with Crohn's disease at diagnosis, and selection of anti-TNFα therapy.

    Summary Background Stricturing and penetrating complications account for substantial morbidity and health-care costs in paediatric and adult onset Crohn’s disease. Validated models to predict risk for complications are not available, and the effect of treatment on risk is unknown. Methods We did a prospective inception cohort study of paediatric patients with newly diagnosed Crohn’s disease at 28 sites in the USA and Canada. Genotypes, antimicrobial serologies, ileal gene expression, and ileal, rectal, and faecal microbiota were assessed.

  3. Update on chancroid: an important cause of genital ulcer disease.

    Chancroid is a major cause of genital ulcer disease worldwide, and occurred at epidemic rates in the United States in the late 1980s. Though the recent epidemic in the U.S. appears to be waning, a number of areas continue to report significant numbers of cases. Chancroid is a particular concern, because, like other diseases that cause genital ulceration, it is associated with an increased risk for transmission or acquisition of human immunodeficiency virus (HIV). Recent studies have advanced the understanding of chancroid epidemiology, and new diagnostic tests may improve the ability to recognize and appropriately treat chancroid. Increased awareness of chancroid, with appropriate treatment for suspected lesions, along with public health efforts to implement prevention in high-risk populations, will be critical to prevent ongoing transmission of chancroid, and potentially ongoing transmission of HIV.

    This editorial briefly reviews studies which might answer the question as to whether radioiodine treatment causes the ophthalmopathy of Graves' disease. However, the data do not allow any conclusion one way or the other. Other possible causal factors are discussed. Further studies are required to define whether treatment of hyperthyroidism aggravates the ophthalmopathy and whether one thereby is worse than the others and by how much. (UK)

    The prospective increase in life expectancy will be accompanied by a rise in the number of elderly people who suffer from ill health caused by old age. Many diseases caused by aging are protein misfolding diseases. The molecular mechanisms underlying these disorders receive constant scientific interest. In addition to old age, mutations also cause congenital protein misfolding disorders. Chorea Huntington, one of the most well-known examples, is caused by triplet extensions that can lead to more than 100 glutamines in the N-terminal region of huntingtin, accompanied by huntingtin aggregation. So far, nine disease-associated triplet extensions have also been described for alanine codons. The extensions lead primarily to skeletal malformations. Eight of these proteins represent transcription factors, while the nuclear poly-adenylate binding protein 1, PABPN1, is an RNA binding protein. Additional alanines in PABPN1 lead to the disease oculopharyngeal muscular dystrophy (OPMD). The alanine extension affects the N-terminal domain of the protein, which has been shown to lack tertiary contacts. Biochemical analyses of the N-terminal domain revealed an alanine-dependent fibril formation. However, fibril formation of full-length protein did not recapitulate the findings of the N-terminal domain. Fibril formation of intact PABPN1 was independent of the alanine segment, and the fibrils displayed biochemical properties that were completely different from those of the N-terminal domain. Although intranuclear inclusions have been shown to represent the histochemical hallmark of OPMD, their role in pathogenesis is currently unclear. Several cell culture and animal models have been generated to study the molecular processes involved in OPMD. These studies revealed a number of promising future therapeutic strategies that could one day improve the quality of life for the patients.

    Alzheimer disease (AD) is the main cortical neurodegenerative disease. The incidence of this disease increases with age, causing significant medical, social and economic problems, especially in countries with ageing populations. This review aims to highlight existing evidence of how vascular dysfunction may contribute to cognitive impairment in AD, as well as the therapeutic possibilities that might arise from this evidence. The vascular hypothesis emerged as an alternative to the amyloid cascade hypothesis as an explanation for the pathophysiology of AD. This hypothesis locates blood vessels as the origin for a variety of pathogenic pathways that lead to neuronal damage and dementia. Destruction of the organisation of the blood brain barrier, decreased cerebral blood flow, and the establishment of an inflammatory context would thus be responsible for any subsequent neuronal damage since these factors promote aggregation of β-amyloid peptide in the brain. The link between neurodegeneration and vascular dysfunction pathways has provided new drug targets and therapeutic approaches that will add to the treatments for AD. It is difficult to determine whether the vascular component in AD is the cause or the effect of the disease, but there is no doubt that vascular pathology has an important relationship with AD. Vascular dysfunction is likely to act synergistically with neurodegenerative changes in a cycle that exacerbates the cognitive impairment found in AD.

    2003-03-01

    Night sweats are a common outpatient complaint, yet literature on the subject is scarce. Tuberculosis and lymphoma are diseases in which night sweats are a dominant symptom, but these are infrequently found to be the cause of night sweats in modern practice. While these diseases remain important diagnostic considerations in patients with night sweats, other diagnoses to consider include human immunodeficiency virus, gastroesophageal reflux disease, obstructive sleep apnea, hyperthyroidism, hypoglycemia, and several less common diseases. Antihypertensives, antipyretics, other medications, and drugs of abuse such as alcohol and heroin may cause night sweats. Serious causes of night sweats can be excluded with a thorough history, physical examination, and directed laboratory and radiographic studies. If a history and physical do not reveal a possible diagnosis, physicians should consider a purified protein derivative, complete blood count, human immunodeficiency virus test, thyroid-stimulating hormone test, erythrocyte sedimentation rate evaluation, chest radiograph, and possibly chest and abdominal computed tomographic scans and bone marrow biopsy.

    Full Text Available A disease presumed to be caused by Fusarium was observed in cocoa open fields with few or without shade trees. Within the population of cocoa trees in the field, some trees had died, some had yellowing leaves and dieback, and the others were apparently healthy. In order to demonstrate Fusarium species as the causal pathogen and to obtain information concerning the incidence of the disease, its distribution and its impact on sustainability of cocoa, isolation of the pathogen, inoculation of cocoa seedlings with isolates and a survey of disease has been conducted. Fusarium was isolated from roots and branches, and inoculated onto cocoa seedlings (one month old via soil. Symptoms appeared within 3-4 weeks after infection. These symptoms consisted of yellowing of leaves beginning from the bottom until the leaves falldown, and browning internal of vascular tissue. Darkened vascular traces in the petiole characteristic of vascularstreak dieback infection were absent. The occurrence of Fusarium in the field was characterized by the absence of obvious signs of fungal infestation on root of infected trees, yellowing of leaves on twigs, dieback, and tree mortality in severe infestations. Disease incidence could reach 77% and in this situation it was difficult for trees recover from heavy infections or to be regenerated in the farm. The study proves that Fusarium is a pathogen causing dieback and the disease is called as Fusarium vascular dieback (FVD. Its development is apparently enhanced by dry conditions in the field. Key words: Fusarium sp., vascular disease, dieback, FVD, Theobroma cacao L.

    Type 1 diabetes is a chronic disease caused by a cell-specific destruction of the insulin producing cells of the pancreas. Although Puerto Rico has the highest incidence of type 1 diabetes among Latin American countries, there is scanty data on the presence of antibodies against insulin producing cells. To this end, 20 children (8 males, 12 females), ages 1-15 years, admitted to the University Pediatric Hospital with type 1 diabetes de novo between November 2000 and April 2001 were prospectively studied to determine the presence of serum antibodies against Islet cells (ICA), glutamic acid decarboxylase (GAD-65) and insulin autoantibodies (IAA). IAA was found to be present in 45% of the subjects with 85% of positive rate in subjects under age 5. GAD-65 was present in 66% and ICA was present in 23% of the subjects. We found evidence of autoimmunity against islet cell surface and intracellular components among a cohort of Puerto Rican children with newly diagnosed type 1 diabetes. These findings compared favorably with reports from other ethnicities.

    To characterize the deaths of 193 children with sickle cell disease screened by a neonatal program from 1998 to 2012 and contrast the initial years with the final years. Deaths were identified by active surveillance of children absent to scheduled appointments in Blood Bank Clinical Centers (Hemominas). Clinical and epidemiological data came from death certificates, neonatal screening database, medical records, and family interviews. Between 1998 and 2012, 3,617,919 children were screened and 2,591 had sickle cell disease (1:1,400). There were 193 deaths (7.4%): 153 with SS/Sβ(0)-thalassemia, 34 SC and 6 Sβ(+)thalassemia; 76.7% were younger than five years; 78% died in the hospital and 21% at home or in transit. The main causes of death were infection (45%), indeterminate (28%), and acute splenic sequestration (14%). In 46% of death certificates, the term "sickle cell" was not recorded. Seven-year death rate for children born between 1998 and 2005 was 5.43% versus 5.12% for those born between 2005 and 2012 (p = 0.72). Medical care was provided to 75% of children; 24% were unassisted. Medical care was provided within 6 hours of symptom onset in only half of the interviewed cases. In 40.5% of cases, death occurred within the first 24 hours. Low family income was recorded in 90% of cases, and illiteracy in 5%. Although comprehensive and effective, neonatal screening for sickle cell disease was not sufficient to significantly reduce mortality in a newborn screening program. Economic and social development and increase of the knowledge on sickle cell disease among health professionals and family are needed to overcome excessive mortality.

    . One of the major goals of the institutions for statutory accident insurance is the prevention of occupational diseases. To perform a successful prevention work it is necessary not only to count the number of accidents or diseases in the various working fields but to look for details of the conditions of work and the human response to those conditions. The institutions for statutory accident insurance have engaged the institution for statutory accident insurance in the precision engineering and electrical industry to carry out documentation, in form of a data bank, for all cases of occupational diseases which could be caused by ionising radiation. Those are not only the cases which are accepted as occupational disease but also the cases where a suspicion of an occupational disease is announced but finally rejected. At the moment about 1700 cases are included in the data bank. For preserving the anonymity information to name and residence are deleted. Various data to one single case are linked by a case-specific key-number. Information to occupation and field of working, to details of a possible exposure to ionising radiation like kind of radiation, time and duration of radiation, exposure of the whole body or of parts of the body and whole body or organ doses are collected. Additional information refers to medical aspects like diagnosis and date of diagnosis. (Author)

    Full Text Available Our knowledge about the microbiota associated with the onset of IBD is limited. The aim of our study was to investigate the correlation between IBD and the fecal microbiota for early diagnosed untreated patients. The fecal samples used were a part of the Inflammatory Bowel South-Eastern Norway II (IBSEN II study and were collected from CD patients (n=30, UC patients (n=33, unclassified IBD (IBDU patients (n=3, and from a control group (n=34. The bacteria associated with the fecal samples were analyzed using a direct 16S rRNA gene-sequencing approach combined with a multivariate curve resolution (MCR analysis. In addition, a 16S rRNA gene clone library was prepared for the construction of bacteria-specific gene-targeted single nucleotide primer extension (SNuPE probes. The MCR analysis resulted in the recovery of five pure components of the dominant bacteria present: Escherichia/Shigella, Faecalibacterium, Bacteroides, and two components of unclassified Clostridiales. Escherichia/Shigella was found to be significantly increased in CD patients compared to control subjects, and Faecalibacterium was found to be significantly reduced in CD patients compared to both UC patients and control subjects. Furthermore, a SNuPE probe specific for Escherichia/Shigella showed a significant overrepresentation of Escherichia/Shigella in CD patients compared to control subjects. In conclusion, samples from CD patients exhibited an increase in Escherichia/Shigella and a decrease in Faecalibacterium indicating that the onset of the disease is associated with an increase in proinflammatory and a decrease in anti-inflammatory bacteria.

    Cortical posterior hypometabolism on PET imaging with 18 F-FDG (FDG-PET), and altered levels of Aß 1-42 peptide, total Tau (tTau) and phosphorylated Tau (pTau) proteins in cerebrospinal fluid (CSF) are established diagnostic biomarkers in Alzheimer's disease (AD). An evaluation has been made of the concordance and relationship between the results of FDG-PET and CSF biomarkers in symptomatic patients with suspected AD. A retrospective review was carried out on 120 patients with cognitive impairment referred to our Cognitive Neurology Unit, and who were evaluated by brain FDG-PET and a lumbar puncture for CSF biomarkers. In order to calculate their Kappa coefficient of concordance, the result of the FDG-PET and the set of the three CSF biomarkers in each patient was classified as normal, inconclusive, or AD-compatible. The relationship between the results of both methods was further assessed using logistic regression analysis, including the Aß 1-42 , tTau and pTau levels as quantitative predictors, and the FDG-PET result as the dependent variable. The weighted Kappa coefficient between FDG-PET and CSF biomarkers was 0.46 (95% CI: 0.35-0.57). Logistic regression analysis showed that the Aß 1-42 and tTau values together were capable of discriminating an FDG-PET result metabolically suggestive of AD from one non-suggestive of AD, with a 91% sensitivity and 93% specificity at the cut-off line Aß 1-42 =44+1.3×tTau. The level of concordance between FDG-PET and CSF biomarkers was moderate, indicating their complementary value in diagnosing AD. The Aß 1-42 and tTau levels in CSF help to predict the patient FDG-PET cortical metabolic status. Copyright © 2017 Elsevier España, S.L.U. y SEMNIM. All rights reserved.

  16. Can we control all-cause meningococcal disease in Europe?

    2016-12-01

    Invasive disease caused by Neisseria meningitidis is potentially devastating, with a case fatality rate of 5-15% and high rates of significant sequelae among survivors after septicaemia or meningitis. Capsular group C (MenC) conjugate vaccines have been highly successful in achieving control of MenC disease across Europe, and some countries have also introduced quadrivalent MenACWY conjugate vaccines to reduce disease caused by groups A, W and Y in addition to C. These vaccines putatively elicit protective levels of bactericidal antibodies in all age groups, induce immunologic memory and reduce nasopharyngeal carriage, thereby leading to herd protection. Protein-based meningococcal vaccines based on subcapsular components, and designed primarily to target capsular group B (MenB) disease, have recently been licensed. These vaccines are highly immunogenic in infants and adolescents, inducing bactericidal antibodies against strains expressing high levels of vaccine antigens which are identical to the variants present in the vaccines. Effectiveness of these vaccines at a population level will be determined by whether vaccine-induced antibodies provide cross-protection against variants of the vaccine antigens present on the surface of the diverse collection of circulating invasive strains. The level of serum bactericidal activity induced against strains also seems to depend on the level of expression of the vaccine antigens. The duration of protection and the impact on carriage of meningococci will have a major bearing on the overall effectiveness of the programme. In September 2015 the UK became the first country to introduce the multicomponent meningococcal serogroup B vaccine (4CMenB) into a national routine immunization schedule, and data on the effectiveness of this programme are anticipated in the next few years.

    Pelvic masses, especially hydatid disease, rarely present with sciatica. We present the computed tomography (CT) and the magnetic resonance imaging (MRI) findings of a 49-year-old female patient with presacral hydatid disease, who was evaluated for her sciatica. We also want to emphasize the importance of assessing the pelvis of patients with symptoms and clinical findings that are inconsistent and that cannot be satisfactorily explained by the spinal imaging findings. isc herniation in the lumbar spine is a well-known etiology of back pains and sciatica, but whenever disc herniation of the lumbar spine is excluded by the employed imaging modalities, then the pelvis should be examined for other possible etiologies of nerve compression. We describe here a patient, who was complaining of sciatica, with no abnormal findings in her lumbar spinal magnetic resonance imaging (MRI). The cause of her sciatica was found to be associated with a pelvic hydatid cyst compressing the lumbosacral nerve plexus. In conclusion, if no pathology is evident for the lumbar discal structures, in connection with the cause of sciatica and lumbar back pains, then the pelvis should also be examined for the possible etiologies of compression of the lumbosacral nerve plexus. Whenever a multiseptated cyst is come across in a patient of an endemic origin with a positive history for hydatid disease like surgery, indicating recurrence, hydatid cyst is the most likely diagnosis.

    Cole disease is a genodermatosis of pigmentation following a strict dominant mode of inheritance. In this study, we investigated eight patients affected with an overlapping genodermatosis after recessive inheritance. The patients presented with hypo- and hyperpigmented macules over the body, resembling dyschromatosis universalis hereditaria in addition to punctuate palmoplantar keratosis. By homozygosity mapping and whole-exome sequencing, a biallelic p.Cys120Arg mutation in ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) was identified in all patients. We found that this mutation, like those causing dominant Cole disease, impairs homodimerization of the ENPP1 enzyme that is mediated by its two somatomedin-B-like domains. Histological analysis revealed structural and molecular changes in affected skin that were likely to originate from defective melanocytes because keratinocytes do not express ENPP1. Consistently, RNA-sequencing analysis of patient-derived primary melanocytes revealed alterations in melanocyte development and in pigmentation signaling pathways. We therefore conclude that germline ENPP1 cysteine-specific mutations, primarily affecting the melanocyte lineage, cause a clinical spectrum of dyschromatosis, in which the p.Cys120Arg allele represents a recessive and more severe form of Cole disease.

    Anthracnose caused by Colletotrichum species is a serious disease of more than 30 plant genera. Several Colletotrichum species have been reported to infect chili in different countries. Although China is the largest chili-producing country, little is known about the species that have been infecting chili locally. Therefore, we collected samples of diseased chili from 29 provinces of China, from which 1285 strains were isolated. The morphological characters of all strains were observed and compared, and multi-locus phylogenetic analyses (ITS, ACT , CAL , CHS-1 , GAPDH , TUB2 , and HIS3 ) were performed on selected representative strains. Fifteen Colletotrichum species were identified, with C. fioriniae , C. fructicola , C. gloeosporioides , C. scovillei , and C. truncatum being prevalent. Three new species, C. conoides , C. grossum , and C. liaoningense , were recognised and described in this paper. Colletotrichum aenigma , C. cliviae , C. endophytica , C. hymenocallidis , C. incanum , C. karstii , and C. viniferum were reported for the first time from chili. Pathogenicity of all species isolated from chili was confirmed, except for C. endophytica . The current study improves the understanding of species causing anthracnose on chili and provides useful information for the effective control of the disease in China.

    Full Text Available American foulbrood (AFB disease is caused by the sporeforming bacterium Paenibacillus larvae larvae. Traditional diagnosis is based on culture technique is time and laboratory work consuming. In this study with standard strain, PCR was developed by specific primers and PCR products were electrophoresed on 0.8 % agarose gel. The PCR primers were selected on the basis of the 16S rRNA gene and amplify a 700-bp amplicon. Detection limits were determined for suspensions of bacteria and spores and also honey and larvae experimentally contaminated. The lowest number of bacteria and spores that were able to detect were respectively 28, 33, 330 and 243 cfu /ml. This PCR technique can be used to identification of the presence of Paenibacillus larvae larvae spores in honey samples, brood samples or on the colonies that grow on medium.

    Although rare in the United States, anti-Mur is relatively common in Southeast Asia and has been reported to have clinical significance in Chinese and Taiwanese populations. The infant was full term and the second child of a Chinese mother and Vietnamese father, presenting with jaundice. He was clinically diagnosed with immune-mediated hemolytic anemia. The direct antiglobulin test indicated that the infant's red blood cells were coated only with anti-IgG. Anti-Mur was identified in the maternal serum and the neonate's plasma. The father was found to be positive for the Mur antigen. The cause of the infant's hemolytic anemia was determined to be most likely anti-Mur. Since anti-Mur is implicated in causing hemolytic disease of the newborn, it is important to recognize this antibody more commonly found in Asian patients in the United States as the Mur+ phenotype has a higher prevalence in this population. © 2016 AABB.

    INTRODUCTION: Newly diagnosed type 2 diabetes mellitus (T2DM) in patients with coronary artery disease (CAD) more than doubles the risk of death compared with otherwise matched glucose tolerant patients. The biguanide metformin is the drug of choice in treatment of T2DM and has shown to ameliorate...... cardiovascular morbidity in patients with T2DM and myocardial infarction (MI). The incretin hormone, glucagon-like peptide-1 (GLP-1) improves β-cell function, insulin sensitivity and causes weight loss and has been suggested to have beneficial effects on cardiac function. The GLP-1 receptor agonist (GLP-1RA......), liraglutide, is currently used for treatment of T2DM but its potential effect on cardiac function has not been investigated in detail. We hypothesised that liraglutide added to metformin backbone therapy in patients with CAD and newly diagnosed T2DM will improve β-cell function and left ventricular systolic...

    Pathological changes of the aging brain are expressed in a range of neurodegenerative disorders that will impact increasing numbers of people across the globe. Research on the causes of these disorders has focused heavily on genetics, and strategies for prevention envision drug-induced slowing or arresting disease advance before its clinical appearance. We discuss a strategic shift that seeks to identify the environmental causes or contributions to neurodegeneration, and the vision of primary disease prevention by removing or controlling exposure to culpable agents. The plausibility of this approach is illustrated by the prototypical neurodegenerative disease amyotrophic lateral sclerosis and parkinsonism-dementia complex (ALS-PDC). This often-familial long-latency disease, once thought to be an inherited genetic disorder but now known to have a predominant or exclusive environmental origin, is in the process of disappearing from the three heavily affected populations, namely Chamorros of Guam and Rota, Japanese residents of Kii Peninsula, Honshu, and Auyu and Jaqai linguistic groups on the island of New Guinea in West Papua, Indonesia. Exposure via traditional food and/or medicine (the only common exposure in all three geographic isolates) to one or more neurotoxins in seed of cycad plants is the most plausible if yet unproven etiology. Neurotoxin dosage and/or subject age at exposure might explain the stratified epidemic of neurodegenerative disease on Guam in which high-incidence ALS peaked and declined before that of PD, only to be replaced today by a dementing disorder comparable to Alzheimer's disease. Exposure to the Guam environment is also linked to the delayed development of ALS among a subset of Chamorro and non-Chamorro Gulf War/Era veterans, a summary of which is reported here for the first time. Lessons learned from this study and from 65 years of research on ALS-PDC include the exceptional value of initial, field-based informal investigation of

    Full Text Available Cancer patients may be at decreased risk of Alzheimer's disease. This hypothesis is best developed for non-melanoma skin cancer (NMSC, but supportive epidemiological data are sparse. We therefore conducted a nationwide cohort study of the association between NMSC and Alzheimer's disease (main outcome and all-cause dementia. Using Danish medical databases, we identified adults diagnosed with NMSC between 1 January 1980 and 30 November 2013 (n = 216,221 and a comparison cohort of five individuals matched to each NMSC patient by sex and birth year (n = 1,081,097. We followed individuals from the time of diagnosis, or corresponding date for matched comparators, until a dementia diagnosis, death, emigration, or 30 November 2013, whichever came first. We used stratified Cox regression adjusted for comorbidities to compute hazard ratios (HRs associating NMSC with dementia. We computed cumulative risks of dementia, treating death as a competing risk. NMSC was associated with a HR of 0.95 (95% confidence interval [CI]: 0.92-0.98 for Alzheimer's disease and 0.92 (95% CI: 0.90-0.94 for all-cause dementia. HRs were similar for basal cell and squamous cell carcinoma, the two most common forms of NMSC. Estimates of risk reduction were more pronounced in the beginning of follow-up, reaching null after 5-10 years. At the end of follow-up (34 years, cumulative risk of Alzheimer's disease was 4.6% (95% CI: 4.4%-4.8% among patients with NMSC vs. 4.7% (95% CI: 4.6%-4.9% in the comparison cohort. In conclusion, NMSC was associated with 2%-10% reductions in relative risks of Alzheimer's disease and all-cause dementia. However, these small inverse associations may have been caused by ascertainment bias due to decreased awareness of NMSC tumors in persons with undiagnosed early cognitive impairment or by confounding from a more neuroprotective lifestyle among persons with NMSC.

    Uromodulin (UMOD)-associated kidney disease belongs to the group of autosomal dominant interstitial kidney diseases and is caused by mutations in the UMOD gene. Affected patients present with hyperuricemia, gout, and progressive renal failure. The disease is thought to be very rare but is probably underdiagnosed. Two index patients from two families with tubulointerstitial nephropathy and hyperuricemia were examined, including blood and urine chemistry, ultrasound, and mutation analysis of the UMOD gene. In addition, other available family members were studied. In a 46-year-old female patient with a fractional excretion of uric acid of 3 %, analysis of the UMOD gene revealed a p.W202S missense mutation. The same mutation was found in her 72-year-old father, who suffers from gout and end-stage renal disease. The second index patient was a 47-year-old female with chronic kidney disease and gout for more than 10 years. Her fractional uric acid excretion was 3.5 %. Genetic analysis identified a novel p.H250Q UMOD mutation that was also present in her 12-year-old son, who had normal renal function and uric acid levels. In patients suffering from chronic tubulointerstitial nephropathy, hyperuricemia, and a low fractional excretion of uric acid mutation, analysis of the UMOD gene should be performed to diagnose UMOD-associated kidney disease.

    123 I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy is a useful tool for differentiating idiopathic Parkinson's disease (PD) from parkinsonism (PS) caused by other disorders. However, cardiac MIBG uptake is affected by various causes. Alternatively, hypoperfusion in the occipital lobe of PD is reported recently. The objective is to clarify the correlation between regional cerebral blood flow (rCBF) alteration and cardiac MIBG uptake in PD. In addition, we examined whether additional brain perfusion analysis improved the differential diagnostic ability for PD from PS when compared with MIBG scintigraphy alone. Forty-nine patients with PD (27 mild groups: Hoehn and Yahr stages I, II; 22 severe groups: Hoehn and Yahr stages III, IV) and 28 patients with PS participated. We compared absolute rCBF values between PD and PS. In addition, we determined correlation between MIBG parameters and each rCBF value. Finally, we compared the diagnostic ability for the differentiation of PD from PS between two diagnostic criteria, each MIBG index abnormality alone [heart-to-mediastinum ratio, H/M (E) 40%] and each MIBG index abnormality or occipital lobe hypoperfusion ( 123 I-MIBG myocardial imaging can be recommended.

  11. Will chronic e-cigarette use cause lung disease?

    Science.gov (United States)

    Rowell, Temperance R; Tarran, Robert

    2015-12-15

    Chronic tobacco smoking is a major cause of preventable morbidity and mortality worldwide. In the lung, tobacco smoking increases the risk of lung cancer, and also causes chronic obstructive pulmonary disease (COPD), which encompasses both emphysema and chronic bronchitis. E-cigarettes (E-Cigs), or electronic nicotine delivery systems, were developed over a decade ago and are designed to deliver nicotine without combusting tobacco. Although tobacco smoking has declined since the 1950s, E-Cig usage has increased, attracting both former tobacco smokers and never smokers. E-Cig liquids (e-liquids) contain nicotine in a glycerol/propylene glycol vehicle with flavorings, which are vaporized and inhaled. To date, neither E-Cig devices, nor e-liquids, are regulated by the Food and Drug Administration (FDA). The FDA has proposed a deeming rule, which aims to initiate legislation to regulate E-Cigs, but the timeline to take effect is uncertain. Proponents of E-Cigs say that they are safe and should not be regulated. Opposition is varied, with some opponents proposing that E-Cig usage will introduce a new generation to nicotine addiction, reversing the decline seen with tobacco smoking, or that E-Cigs generally may not be safe and will trigger diseases like tobacco. In this review, we shall discuss what is known about the effects of E-Cigs on the mammalian lung and isolated lung cells in vitro. We hope that collating this data will help illustrate gaps in the knowledge of this burgeoning field, directing researchers toward answering whether or not E-Cigs are capable of causing disease.

    Full Text Available From 1992 onwards, outbreaks of a previously unknown illness have been reported in Asian seabass (Lates calcarifer kept in maricultures in Southeast Asia. The most striking symptom of this emerging disease is the loss of scales. It was referred to as scale drop syndrome, but the etiology remained enigmatic. By using a next-generation virus discovery technique, VIDISCA-454, sequences of an unknown virus were detected in serum of diseased fish. The near complete genome sequence of the virus was determined, which shows a unique genome organization, and low levels of identity to known members of the Iridoviridae. Based on homology of a series of putatively encoded proteins, the virus is a novel member of the Megalocytivirus genus of the Iridoviridae family. The virus was isolated and propagated in cell culture, where it caused a cytopathogenic effect in infected Asian seabass kidney and brain cells. Electron microscopy revealed icosahedral virions of about 140 nm, characteristic for the Iridoviridae. In vitro cultured virus induced scale drop syndrome in Asian seabass in vivo and the virus could be reisolated from these infected fish. These findings show that the virus is the causative agent for the scale drop syndrome, as each of Koch's postulates is fulfilled. We have named the virus Scale Drop Disease Virus. Vaccines prepared from BEI- and formalin inactivated virus, as well as from E. coli produced major capsid protein provide efficacious protection against scale drop disease.

    The present study is to determine the prevalence and implication of coeliac disease (CD) among adult Saudis and compared to those with diagnosed irritable bowel syndrome. This prospective study was conducted among 980 adults. Out of that, 482 subjects (staff and students of Riyadh Health Science College) were designated as control cohorts for undetected coeliac disease. Furthermore, another contingent of 498 subjects diagnosed with irritable bowel syndrome (IBS) at Prince Salman Hospital and Al-Iman General Hospital also constituted a segment of the overall initial 1020 subjects. Both cases and control were tested for serological markers of coeliac disease (tissues transglutaminase (tTGAs) and endomysial autoantibody (EMAs) and were confirmed by histopathology test. All the positive for cases of coeliac disease were screened for iron deficiency anaemia, Vitamin D deficiency, and osteoporosis and weight assessment. The percentage of coeliac disease in control subjects and patients diagnosed with irritable bowel syndrome (IBS) were found to be 1.9% and 9.6% respectively, about 38% of the total coeliac disease patients are among females of middle age (20-39-years) and 16% of the males in the same age range. Whereas, 20% and 25% of all coeliac disease cases with ages of 40-59 were remarked as females and males respectively. The identical nature and overlap of symptoms of the two conditions could possibly result in misdiagnosis of coeliac diseases or over-diagnosis of irritable bowel syndrome. The findings of the study might also give considerable implications of the disease in the nutritional level which is noticeable.

    2006-01-01

    Objective: The superior vena cava (SVC) obstruction by malignant diseases is either by direct invasion and compression or by tumour thrombus of the SVC. Whatever is its cause, obstruction of the SVC causes elevated pressure in the veins draining into the SVC and increased or reversed blood flow through collateral vessels. Severity of the syndrome depends on the collateral vascular system development. Therefore, imaging of the collateral veins with variable location and connection is important in determining the extension and management of the disease. Our aims are to describe collateral vessels of the superior vena cava syndrome (SVCS) related with the malignant diseases and to assess the ability of multi-detector row CT with multiplanar and 3D volume rendering techniques in determining and describing collateral circulations. Materials and methods: We present CT angiography findings of seven patients with small cell carcinoma of the lung (n = 2), squamous cell carcinoma of the lung (n = 3), Hodgkin disease of the thorax (n = 1), and squamous cell carcinoma of the oesophagus (n = 1). The patients received contrast-enhanced CT scans of the chest and abdomen on a multi-detector row CT during breath holding at suspended inspiration. Results: CT images revealed the cause and level of the SVC obstruction in all patients with axial and multiplanar reconstructed images. The SVC showed total obstruction in five patients and partial obstruction in two patients. The most common experienced collateral vessels were azygos vein (6), intercostal veins (6), mediastinal veins (6), paravertebral veins (5), hemiazygos vein (5), thoracoepigastric vein (5), internal mammary vein (5), thoracoacromioclavicular venous plexus (5), and anterior chest wall veins (5). While one case showed the portal-systemic shunt, V. cordis media and sinus coronarius with phrenic veins were enlarged in two cases, and the left adrenal vein was enlarged in a patient.

  20. Incidence of end-stage renal disease attributed to diabetes among persons with diagnosed diabetes --- United States and Puerto Rico, 1996-2007.

    Science.gov (United States)

    2010-10-29

    During 2007, approximately 110,000 persons in the United States and Puerto Rico began treatment for end-stage renal disease (ESRD) (i.e., kidney failure requiring dialysis or transplantation). Diabetes is the leading cause of ESRD in the United States, accounting for 44% of new cases in 2007. Although the number of persons initiating treatment for kidney failure each year who have diabetes listed as a primary cause (ESRD-D) has increased since 1996, ESRD-D incidence among persons with diagnosed diabetes has declined since 1996. To determine whether this decline occurred in every U.S. region and in every state, CDC analyzed 1996-2007 data from the U.S. Renal Data System (USRDS) and the Behavioral Risk Factor Surveillance System (BRFSS). During the period, the age-adjusted rate of ESRD-D among persons with diagnosed diabetes declined 35% overall, from 304.5 to 199.1 per 100,000 persons with diagnosed diabetes, and declined in all U.S. regions and in most states. No state showed a significant increase in the age-adjusted ESRD-D rate. Continued awareness of risk factors for kidney failure and interventions to improve diabetes care are needed to sustain and improve these trends.

    Cecal volvulus is an acute surgical condition that is extremely rare in children, with a mortality rate of up to 40%. The clinical symptoms are often non-specific, and pediatric patients frequently have neurological deficits with associated communication difficulties, making the clinical diagnosis extremely challenging. Conventional radiographic imaging studies play a key role in the prospective diagnosis in children. We report a rare case of cecal volvulus in a 12-year-old boy who was diagnosed pre-operatively by abdominal radiographs and a contrast enema. (orig.)

  3. Unstable mutations: cause of some neurological hereditary diseases

    International Nuclear Information System (INIS)

    Cuenca Berger, P.; Morales Montero, F.

    1999-01-01

    Unstable mutations or amplification of triplets constitute a kind of genetic alteration discovered during the last decade. They had been found inside or near genes important for the normal neurological function of the human being. In some cases, the presence of the amplification causes the inactivation of the gene or the synthesis of a new product which functions different from the original protein. Some common characteristics of diseases caused by the amplification of triplets are that it affects the nervous system and are degenerative in nature. The expression of the manifestations varies according to age. Most of them show genetic anticipation in which the severity of the manifestations increases with each generation and appear at an earlier age. In most cases, the severity of the symptoms is correlated positively to the size of the amplification. The diagnosis of an affected individual in a family may indicate the presence of an altered gene in other relatives. These relatives may not present evident signs of the illness either because it is of late onset or because they carry premutations. The molecular diagnosis of these mutations is important to estimate the risk of developing the disease and/or of transmitting the illness to the descendants and to eliminate the fears of healthy relatives who have inherited normal copies of the gene.

    To report clinical features of patients with retinal and choroidal diseases presenting with acute visual disturbance during pregnancy. In this retrospective case series, patients who developed acute visual loss during pregnancy (including puerperium) and visited a tertiary hospital from July 2007 to June 2015, were recruited by searching electronic medical records. Patients were categorized according to the cause of visual loss. Clinical features and required diagnostic modalities were analyzed in the retinal and choroidal disease group. Acute visual loss occurred in 147 patients; 49 (38.9%) were classified into the retinal and choroidal group. The diagnoses included central serous chorioretinopathy (22.4%), hypertensive retinopathy with or without pre-eclampsia (22.4%), retinal tear with or without retinal detachment (18.4%), diabetic retinopathy progression (10.2%), Vogt-Koyanagi-Harada disease (4.1%), retinal artery occlusion (4.1%), multiple evanescent white dot syndrome (4.1%), and others (14.3%). Visual symptoms first appeared at gestational age 25.9 ± 10.3 weeks. The initial best-corrected visual acuity (BCVA) was 0.27 ± 0.39 logarithm of the minimum angle of resolution (logMAR); the final BCVA after delivery improved to 0.13 ± 0.35 logMAR. Serious visual deterioration (BCVA worth than 20 / 200) developed in two patients. Differential diagnoses were established with characteristic fundus and spectral-domain optical coherence tomography findings in all cases. In pregnant women with acute visual loss, retinal and choroidal diseases are common and could be vision threatening. Physicians should be aware of pregnancy-associated retinal and choroidal diseases and their clinical features. The differential diagnosis can be established with non-invasive techniques. © 2017 The Korean Ophthalmological Society

    X-ray computed tomography (CT) has been used for diagnosis of pulmonary emphysema because it can reveal the morphology of low attenuation areas. Recently, 99m Tc-Technegas imaging, one of several types of scintigraphic techniques, has been used for ventilation scintigraphy. Technegas scintigraphy was performed on 15 patients with pulmonary emphysema, and we compared the extent and degree of abnormal findings on Technegas scintigraphy with the extent of low attenuation areas shown by CT. We classified the findings of Technegas imaging into three grades, from mild to severe, according to the extent of peripheral irregularity and central hot spot formation. We also classified the findings of CT as centrilobular emphysema into three grades from mild to severe according to the extent of low attention areas in the peripheral lung fields. In 5 cases, CT and Technegas assessment resulted in equivalent diagnoses. In eight cases, Technegas images showed more detailed findings than CT images. In the two remaining cases, which were diagnosed as panlobular emphysema on CT, Technegas images showed the severe stage. Technegas scintigraphy was useful for diagnostic assessment of pulmonary emphysema, especially for panlobular emphysema, which is difficult to distinguish from the normal lung condition by CT assessment.

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

    Chronic regurgitation of gastric acids in patients with gastroesophageal reflux disease may cause dental erosion, which can lead in combination with attrition or bruxism to extensive loss of coronal tooth tissue. This clinical report describes treatment of severe tooth wear of a gastroesophageal reflux disease patient who is 54-year-old Turkish male patient. After his medical treatment, severe tooth wear, bruxism and decreased vertical dimensions were determined. The vertical dimension was re-established and maxillary and mandibular anterior and posterior teeth were prepared for metal-ceramic restorations. Metal-ceramic fixed partial dentures were fabricated as full mouth restorations for both maxillary and mandibular arches because of splinting all teeth. And then maxillary stabilization splint was fabricated for his bruxism history. Significant loss of coronal tooth structure must taken into consideration. Gastroesophageal reflux disease by itself or in combination with attrition, abrasion or bruxism may be responsible for the loss. An extensive diagnostic evaluation is essential for the medical and dental effects of the problem.

    Objective: This study was done to evaluate frequency of acute renal failure ( ARF ), its causes and out come of the patients. Study Design: Descriptive analytic study Place and Duration of Study: March to Dec 2007 at Combined Military Hospital Lahore. Patients and Methods: All patients, admitted in different wards of the hospital, who developed acute renal failure (doubling of serum creatinine measured on two occasions 12 hours apart), were included in this study. Results: A total of 39 patients were included in the study. Males were 19 (48.71%) and 20 (51.28%) were female. Mean age of patients was 40.2 years (SD=18.0). The major cause was acute Gastroenteritis seen in 23 (58.97%) cases. Others developed ARF due to, Abruptio Placentae 5 (12.82%), Postoperative 5 (12.82%), Eclampsia 3 (7.69%) and Drug induced 3 (7.69%) . Oliguric phase developed in 28 (71.79%) patients and lasted for 8.45 +- 4.16 days. Of these 17 (60.71%) patients had acute gastroenteritis. Conclusion: Gastroenteritis is the most common and important cause of ARF though gynaecological and surgical etiologies must be kept in mind. It is evident that the gynaecological and surgical patients need critical peri-partum and peri-operative monitoring to prevent development of ARF. Early institution of therapy will prevent subsequent morbidity associated with this disease. (author)

    International genome sequencing projects have produced billions of nucleotides (letters) of DNA sequence data, including the complete genome sequences of 74 organisms. These genome sequences have created many new scientific opportunities, including the ability to identify sequence variations among individuals within a species. These genetic differences, which are known as single nucleotide polymorphisms (SNPs), are particularly important in understanding the genetic basis for disease susceptibility. Since the report of the complete human genome sequence, over two million human SNPs have been identified, including a large-scale comparison of an entire chromosome from twenty individuals. Of the protein coding SNPs (cSNPs), approximately half leads to a single amino acid change in the encoded protein (non-synonymous coding SNPs). Most of these changes are functionally silent, while the remainder negatively impact the protein and sometimes cause human disease. To date, over 550 SNPs have been found to cause single locus (monogenic) diseases and many others have been associated with polygenic diseases. SNPs have been linked to specific human diseases, including late-onset Parkinson disease, autism, rheumatoid arthritis and cancer. The ability to predict accurately the effects of these SNPs on protein function would represent a major advance toward understanding these diseases. To date several attempts have been made toward predicting the effects of such mutations. The most successful of these is a computational approach called ''Sorting Intolerant From Tolerant'' (SIFT). This method uses sequence conservation among many similar proteins to predict which residues in a protein are functionally important. However, this method suffers from several limitations. First, a query sequence must have a sufficient number of relatives to infer sequence conservation. Second, this method does not make use of or provide any information on protein structure, which

    A technique to dig valuable information buried or hidden in data collection which is so big to be found an interesting patterns that was previously unknown is called data mining. Data mining has been applied in the healthcare industry. One technique used data mining is classification. The decision tree included in the classification of data mining and algorithm developed by decision tree is C4.5 algorithm. A classifier is designed using applying pessimistic pruning in C4.5 algorithm in diagnosing chronic kidney disease. Pessimistic pruning use to identify and remove branches that are not needed, this is done to avoid overfitting the decision tree generated by the C4.5 algorithm. In this paper, the result obtained using these classifiers are presented and discussed. Using pessimistic pruning shows increase accuracy of C4.5 algorithm of 1.5% from 95% to 96.5% in diagnosing of chronic kidney disease.

    A 45 year-old-man was admitted to our hospital because of discomfort in his left scrotum. He had a left testicular tumor. We performed high orchiectomy and pathological findings revealed testicular cancer. He was treated with bleomycin, etoposide and cisplatin. Computed tomography showed a new mass in the left lung after 3 cycles of the chemotherapy. Because of its rapid growth, the tumor was thought to be a metastasis lesion of testicular cancer or pulmonary infection. Transbronchial lung biopsy showed an invasion of multinucleated giant cells and granuloma. The culture and polymerase chain reaction of the bronchial sputum were positive for myobacterium avium-complex (MAC). From these findings, the left lung tumor was diagnosed as pulmonary MAC disease. He received partial resection of the left lung and the lesion was diagnosed as granuloma. There was no recurrence of testicular cancer or pulmonary disease after the surgery.

    Full Text Available Abstract Background Electronic linkage to routine administrative datasets, such as the Hospital Episode Statistics (HES in England, is increasingly used in medical research. Relatively little is known about the reliability of HES diagnostic information for epidemiological studies. In the United Kingdom (UK, general practitioners hold comprehensive records for individuals relating to their primary, secondary and tertiary care. For a random sample of participants in a large UK cohort, we compared vascular disease diagnoses in HES and general practice records to assess agreement between the two sources. Methods Million Women Study participants with a HES record of hospital admission with vascular disease (ischaemic heart disease [ICD-10 codes I20-I25], cerebrovascular disease [G45, I60-I69] or venous thromboembolism [I26, I80-I82] between April 1st 1997 and March 31st 2005 were identified. In each broad diagnostic group and in women with no such HES diagnoses, a random sample of about a thousand women was selected for study. We asked each woman’s general practitioner to provide information on her history of vascular disease and this information was compared with the HES diagnosis record. Results Over 90% of study forms sent to general practitioners were returned and 88% of these contained analysable data. For the vast majority of study participants for whom information was available, diagnostic information from general practice and HES records was consistent. Overall, for 93% of women with a HES diagnosis of vascular disease, general practice records agreed with the HES diagnosis; and for 97% of women with no HES diagnosis of vascular disease, the general practitioner had no record of a diagnosis of vascular disease. For severe vascular disease, including myocardial infarction (I21-22, stroke, both overall (I60-64 and by subtype, and pulmonary embolism (I26, HES records appeared to be both reliable and complete.

    The aim of this study was to evaluate eating habits and nutritional behaviors of women in the perimenopausal period with celiac disease diagnosed within the last 4 years. The study covered a group of 26 women, at the age of 51-54 years, with celiac disease diagnosed in the last 4 years and staying on a gluten-free diet for 6 months to 4 years and agreed to participate in this studies. Information of nutrition were collected from the women, who, after an appropriate instruction, recorded the timing, type and amount of food consumed in the three days a week, selected at random. The amount of consumed portions was defined on the basis of the "Book of portions, products and dishes". The menus (78) were recorded in April and May. Collected data were prepared, based on a computer program Dietetyk 2009 Prof. The analysis of results achieved in this study enabled concluding that--from the viewpoint of the diagnosed disease--the nutritional patterns of the women were very appropriate. However, it failed to meet basic nutritional guidelines, which was reflected in, among other things, unsatisfactory intake of vegetables, fruits, oils and water, and in excessive intake of protein of animal origin. In addition, it did not cover demands resulting from the perimenopausal period the surveyed women were in, which is likely to facilitate, e.g. disorders in lipid metabolism and water-mineral balance, as well as development of osteoporosis. The general picture of behaviors, including the nutritional ones, pointed to a strong predominance of the diagnosed disease but also to the need of compensating for the resultant restrictions, with the latter being perceived by the surveyed women as health-promoting actions.

    The terms medullary cystic disease, juvenile nephronophthisis or medullary cystic disease complex refer to a group of similar diseases in which the basic pathological abnormality is progressive renal tubular atrophy with secondary glomerular sclerosis and medullary cystic formation. Medullary cystic disease is an important cause of renal failure in adolescent patients. Imaging methods play a primary role in the diagnosis of these diseases. Cysts are characteristically seen in the renal medulla and cortico medullary junction whereas kidneys may be of normal to small size. In this article we present the ultrasonography and computed tomography findings of a female adolescent patient with characteristic clinical picture of medullary cystic disease. (author)

    The refollow-up has been carried out in hypothyroidism caused by 131 I treatment for Graves disease. The serum HS-TSH(IRMA), FT3, TSH(RIA), TT3, TT4, FT4I, MCA, TGA, Cholesterol and Triglyceride has been measured in 26 patient after 131 I treatment for 9.5 years in average. At the same time TRH stimulation test was also performed, and the clinical symptoms and signs assessed. The results showed that TSH is the most sensitive criterion for hypothyroidism, followed by Cholesterol and FT 4 I. The occurence of hypothyroidism may be related to the presence of thyroid antibody as demonstrated by the elevation of serum MCA, TGA. Therefore measurement of serum TSH, FT 4 I and Cholesterol during long term follow-up is beneficial for early diagnosis of hypothyroidism and evaluating the effect of substitution treatment

    Insomnia is a large health problem. In some prior studies, positive associations between insomnia symptoms and sickness absence have been observed. There is, however, no previous nationwide cohort study of clinically diagnosed insomnia and risk of incident sickness absence. Prospective nationwide cohort study based on Swedish population-based registers including all 4,956,358 individuals registered as living in Sweden on 31 December 2004/2005, aged 17-64 years, not on disability pension, old-age pension or on-going sickness absence. Those having insomnia inpatient or outpatient care, defined as having at least one admission/specialist visit with a main or secondary diagnosis of disorders of initiating and maintaining sleep [insomnias] (ICD-10: G47.0) during 2000/2001-2005, were compared to those with no such care. All-cause and diagnosis-specific incident sickness absence were followed during 2006-2010. Incidence rate ratios (IRRs) and 95% confidence intervals (CIs) were estimated by Cox proportional hazards regression. In models adjusted for prior sickness absence, socio-demographic factors and inpatient and specialized outpatient care, associations between insomnia and increased risks of all-cause sickness absence (IRR 1.18, 95% CI 1.04-1.35) and sickness absence due to mental diagnoses (IRR 1.75, 95% CI 1.36-2.25) were observed. After further adjustment for insomnia medications these associations disappeared. No associations between insomnia and risk of sickness absence due to cancer, circulatory or musculoskeletal diagnoses, or injuries, were observed. In this nationwide cohort study, we observed increased risks of all-cause sickness absence and sickness absence due to mental diagnoses after adjustment for several potential confounders that disappeared after further adjustment for insomnia medications.

  19. Hypoxemia in patients with COPD: cause, effects, and disease progression.

    LENUS (Irish Health Repository)

    Kent, Brian D

    2012-02-01

    Chronic obstructive pulmonary disease (COPD) is a leading cause of death and disability internationally. Alveolar hypoxia and consequent hypoxemia increase in prevalence as disease severity increases. Ventilation\\/perfusion mismatch resulting from progressive airflow limitation and emphysema is the key driver of this hypoxia, which may be exacerbated by sleep and exercise. Uncorrected chronic hypoxemia is associated with the development of adverse sequelae of COPD, including pulmonary hypertension, secondary polycythemia, systemic inflammation, and skeletal muscle dysfunction. A combination of these factors leads to diminished quality of life, reduced exercise tolerance, increased risk of cardiovascular morbidity, and greater risk of death. Concomitant sleep-disordered breathing may place a small but significant subset of COPD patients at increased risk of these complications. Long-term oxygen therapy has been shown to improve pulmonary hemodynamics, reduce erythrocytosis, and improve survival in selected patients with severe hypoxemic respiratory failure. However, the optimal treatment for patients with exertional oxyhemoglobin desaturation, isolated nocturnal hypoxemia, or mild-to-moderate resting daytime hypoxemia remains uncertain.

  20. Pheromones cause disease: the exocrinology of anorexia nervosa.

    Science.gov (United States)

    Nicholson, B

    2000-03-01

    The aetiology of anorexia nervosa is exocrinological. This notion is supported by physical evidence in animal models with directly comparable symptomatology. Anorexia nervosa (AN) syndrome would be a puberty delay caused by reception and autoreception of conspecific pheromone emissions: a pheromone-induced puberty delay (PIPD). As such, it would be amenable to medical treatment drawing from forty years of research in animals. This hypothesis is testable. For instance, since food ad libitum is a prerequisite for PIPD, occasional supervised fasting in healthy peripuberal subjects should prevent AN. Besides, tolerating an untestable thought disease (1,2) with symptoms of a curable well-understood animal condition would be anti-scientific and perpetuates medical disaster. Even their endocrinologies are identical. Pheromone feedback tunes animal appetites and immunity to available resources and prospects. In addition to timing puberty, pheromones regulate fertility. Pheromones will probably be implicated in the aetiology of the psychiatric and autoimmune diseases. This is the second in a series of twelve papers to explore this contention systematically.

    2014-01-01

    Individuals with Parkinson's disease (PD) commonly experience freezing of gait under time constraints, in narrow spaces, and in the dark. One commonality between these different situations is that they may all provoke anxiety, yet anxiety has never been directly examined as a cause of FOG. In this study, virtual reality was used to induce anxiety and evaluate whether it directly causes FOG. Fourteen patients with PD and freezing of gait (Freezers) and 17 PD without freezing of gait (Non-Freezers) were instructed to walk in two virtual environments: (i) across a plank that was located on the ground (LOW), (ii) across a plank above a deep pit (HIGH). Multiple synchronized motion capture cameras updated participants' movement through the virtual environment in real-time, while their gait was recorded. Anxiety levels were evaluated after each trial using self-assessment manikins. Freezers performed the experiment on two separate occasions (in their ON and OFF state). Freezers reported higher levels of anxiety compared to Non-Freezers (panxiety when walking across the HIGH plank compared to the LOW (panxiety is an important mechanism underlying freezing of gait and supports the notion that the limbic system may have a profound contribution to freezing in PD.

    The incidence and complications of peptic ulcer disease (PUD) have declined, but mortality from bleeding ulcers has remained unchanged. The aims of the current study were to evaluate the significance of PUD among patients admitted for acute upper endoscopy and to evaluate the survival of PUD patients. In this prospective, observational cohort study, data on 1580 acute upper endoscopy cases during 2012-2014 were collected. A total of 649 patients were included with written informed consent. Data on patients' characteristics, living habits, comorbidities, drug use, endoscopy and short-term and long-term survival were collected. Of all patients admitted for endoscopy, 147/649 (23%) had PUD with the main symptom of melena. Of these PUD patients, 35% had major stigmata of bleeding (Forrest Ia-IIb) in endoscopy. Patients with major stigmata had significantly more often renal insufficiency, lower level of blood pressure with tachycardia and lower level of haemoglobin, platelets and ratio of thromboplastin time. No differences in drug use, Charlson comorbidity class, BMI, smoking or alcohol use were found. Of the PUD patients, 31% were Helicobacter pylori positive. The 30-day mortality was 0.7% (95% confidence interval: 0.01-4.7), 1-year mortality was 12.9% (8.4-19.5) and the 2-year mortality was 19.4% (13.8-26.8), with no difference according to major or minor stigmata of bleeding. Comorbidity (Charlson>1) was associated with decreased survival (P=0.029) and obesity (BMI≥30) was associated with better survival (P=0.023). PUD is still the most common cause for acute upper endoscopy with very low short-term mortality. Comorbidity, but not the stigmata of bleeding, was associated with decreased long-term survival.

    Low-back pain diseases (LBPD) belong to the most frequent diagnoses determined by general practitioners, and constitute one of the most common reasons for sick leave and permanent disability pension in the Czech Republic and other European countries. Epidemiological studies have shown a statistically significant association between LBPD and certain types of occupational burden. However, in the Czech Republic, LBPD caused by overload and/or whole-body vibrations have not yet been included in the list of occupational diseases. The aim of this study was to collect and compare the systems, criteria and diagnoses used to recognize LBPD as occupational diseases in other European countries. A questionnaire focused on LBPD was distributed and answered by specialists in occupational diseases in European countries. It included items concerning LBPD in the national list of occupational diseases, and work-related and diagnostic criteria that need to be fulfilled for recognizing LBPD as occupational diseases and possible awarding compensations to the patients. In 13 countries out of the 23 countries studied, LBPD caused by overload can be recognized as occupational, providing that the diagnosis is sufficiently proven and exposure criteria and/or listed occupation are met and duration of exposure is confirmed (Belgium, Denmark, France, Germany, Hungary, Italy, Lithuania, Macedonia, Netherlands, Romania, Slovakia, Sweden, and Switzerland). LBPD due to vibrations can be also recognized as occupational in 14 countries. In 8 countries LBPD are not accepted as occupational unless they are caused by an injury at work. Specific criteria to evaluate occupational exposure of patients with LBPD were set in Belgium, Denmark, France, Germany, Lithuania, Macedonia, Netherlands, and Slovakia. In other countries, the evaluation is done at an individual basis. In practice, the assessment of occupational overload and its contribution to the development of LBPD as well as its inclusion in the

    We report a patient with multiple brain abscesses due to Staphylococcus cohnii. While these brain abscesses markedly responded to the antibiotics, this patient was subsequently suffered from subcutaneous inflammatory nodules in the adipose tissue, which diagnosed him as having Weber-Christian disease (WCD). This is the first report that subcutaneous inflammatory nodules in the adipose tissue, which lead the diagnosis of WCD, followed multiple brain abscesses. To our knowledge, S. cohnii has not yet been reported to cause multiple brain abscesses in humans. Although the etiology of WCD is unknown, an immune mechanism has been implicated in the pathogenesis. Therefore, we should notice that patients with WCD could be immunocompromised hosts with a higher risk to suffer from severe opportunistic infections.

    BACKGROUND: IGF1 is believed to influence ageing and development of cardiovascular disease (CVD) through complex mechanisms. Reduced IGF1 levels might be causally associated with conditions accompanying ageing including development of CVD. However, in animal models reduced GH-IGF1 signalling...... increases lifespan. Reduced IGF1 activity might also be associated with longevity in humans. OBJECTIVE: The objective was to investigate if plasma IGF1 levels were associated with all cause mortality, and the development of chronic heart failure (CHF) and a major CV event.

  7. Malignant lymphoma incidentally diagnosed due to the perforation of the small intestine caused by a fish bone: A case report

    Directory of Open Access Journals (Sweden)

    Masatsugu Hiraki

    Full Text Available Introduction: The ingestion of a foreign body is relatively common. However, it rarely results in the perforation of gastrointestinal tract. We herein report an unusual case of malignant lymphoma incidentally diagnosed after the perforation of the small intestine by a fish bone. Presentation of case: A 90-year-old woman was admitted to our hospital because of abdominal pain and vomiting. Abdominal computed tomography demonstrated free air and ascites in the abdominal cavity. In the pelvic cavity, a radiopaque linear shadow about 35 mm in diameter was shown in the small intestine, and the stricture was exposed to the abdominal cavity. Therefore, a diagnosis of perforation of the small intestine due to ingestion of a foreign body and panperitonitis was made. Emergent laparotomy was performed. The intraoperative findings revealed perforation of the small intestine with a fish bone in the jejunum. Local inflammation at the perforation site was seen, and circulated wall thickness was observed at the distal side of the jejunum. Partial resection of the jejunum and anastomosis of jejuno-jejunostomy was performed. A pathological examination and immunohistochemical study of the resected specimen resulted in a diagnosis of malignant lymphoma of follicular lymphoma Grade 1. Discussion: It is very difficult to identify the existence malignancy accompanied with gastrointestinal perforation with ingestion of a foreign body. Conclusion: In cases suspected of involving malignancy, careful observation during surgery is needed in order to avoid missing the accompanying malignancy.

    BACKGROUND: Systematic follow-up is currently not recommended for patients with simple congenital heart disease; however, only a few data exist on the long-term prognosis of simple congenital heart disease. METHODS AND RESULTS: We undertook a nationwide follow-up study of a cohort of 1241 simple...... congenital heart disease patients, diagnosed from 1963 through 1973, in otherwise healthy children and alive at 15 years of age. We identified 10 age- and sex-matched general population controls per patient. We followed the study population through Danish public registries from the age of 15 years up...... with simple congenital heart disease in the 1960s have substantially increased long-term mortality and cardiac morbidity compared with the general population. Further studies on the effectiveness of systematic medical follow-up programs appear warranted....

    Differences in the prevalence of left and right congenital heart defects (CHD) across the United States are unclear. This study evaluated the overall prevalence and the distribution of right versus left CHD across US regions and divisions in neonates. Newborns born from 2000 to 2014 diagnosed with CHD were identified using the National Inpatient Sample. Heart defects were stratified into right, left, and "neither" subtypes. The risk of right and left heart diagnoses between US Census regions and divisions was compared using multivariable binomial regression, adjusting for infant, and hospital characteristics. Two hundred forty thousand four hundred fifty-five newborns were included and 38,185 (15.9%) were classifiable as having either right or left subtypes. Between 2000 and 2014, the prevalence of right defects increased from 1.65 to 2.88 cases/1,000 live born infants (p right heart defect diagnosis compared to the West. When stratified by division, New England states had a significantly higher prevalence of right defects compared to the Pacific (RD adj .09, 95% CI .06, 0.11). No differences in the prevalence of left defects were seen. The prevalence of CHD diagnoses at birth in the US has increased, and regional differences in the prevalence of right defects appear to exist. © 2017 Wiley Periodicals, Inc.

    This study sought to identify factors associated with intention to change sexual practices among heterosexual Thai males diagnosed with sexually transmitted infections (STIs). STI clinic patients (n = 247) reported their sexual behaviors and condom use during the previous 3 months. STI and HIV knowledge, motivation to change sexual practices, and behavioral skills were assessed. Then, self-reported behavior change intention, including consistent condom use, reducing number of sexual partners, not using drugs and alcohol when having sex, and refusal of condomless sex, was examined. Consistent condom use in the past 3 months by Thai males diagnosed with STIs was low across all types of sexual partners (lover 13.8%, casual partner 14.9%, and sex worker 2.5%). Risk reduction self-efficacy (p behavior change intention. Significant predictors of behavior change intention were risk reduction self-efficacy (p behavior change intention variance. Intervention aimed at enhancing motivation and behavioral skills to adopt preventive behaviors should be developed to prevent recurrent STIs, including HIV infection, among heterosexual Thai males diagnosed with STIs.

    Idiopathic basal ganglia calcification (IBGC) is a rare, intractable disease with unknown etiology. IBGC3 is a familial genetic disease defined by genetic mutations in the major causative gene ( SLC20A2 ). People with IBGC3 experience distress from the uncommon nature of their illness and uncertainty about treatment and prognoses. The present study aimed to describe the lives and illness of people with IBGC3. Participants were recruited from patients aged 20 years or older enrolled in a genetic study, who were diagnosed with IBGC3 and wanted to share their experiences. In-depth semi-structured interviews were conducted with six participants. Interviews were conducted between December 2012 and February 2014, and were recorded and transcribed verbatim. Qualitative data analysis was performed to identify categories and subcategories. Efforts were made to ensure the credibility, transferability, dependability, conformability, and validity of the data. Six thematic categories, 17 subcategories, and 143 codes emerged. The six categories were: (1) Frustration and anxiety with progression of symptoms without a diagnosis; (2) Confusion about diagnosis with an unfamiliar disease; (3) Emotional distress caused by a genetic disease; (4) Passive attitude toward life, being extra careful; (5) Taking charge of life, becoming active and engaged; and (6) Requests for healthcare. The qualitative data analysis indicated a need for genetic counseling, access to disease information, establishment of peer and family support systems, mental health services, and improvement in early intervention and treatment for the disease.

    We investigated the association of thiazolidinedione and its dose effect with the risk of Parkinson's disease (PD) in patients with diabetes mellitus (DM). This study enrolled 38,521 patients with newly-diagnosed DM between 2001 and 2013 and compared them to matched subjects without DM. The hazard ratios (HRs) for PD were compared between the thiazolidinedione-treated and non-thiazolidinedione-treated groups of the study cohort, and between subgroups who received different cumulative dosages of thiazolidinedione. We observed 544 (1.4%) patients with PD during the follow up of median duration of 6.2 years in patients with newly-diagnosed DM who had a higher risk for PD than patients without DM (HR = 1.150). In the study cohort, the risk of PD was significantly lower in the thiazolidinedione-treated group (HR = 0.399) compared to the non-thiazolidinedione-treated group. Thiazolidinedione reduced the risk of PD in a dose-dependent manner, with HRs ranging from 0.613 to 0.081 with defined daily doses of 0-90 to > 720, respectively. Thiazolidinedione use was associated with a significantly reduced risk of PD in patients with newly-diagnosed DM. Further studies to elucidate the common mechanism of PD and DM may provide novel therapies for these two diseases.

    While inadequate food and communicable infectious diseases have been a concern of researchers and policy makers in Africa, little attention has been given to obesity and chronic, non-communicable diseases. Africa is not usually associated with obesity and chronic diseases. Yet there has been a sharp rise in the incidence of obesity and chronic diseases, a major public health problem in many countries. The paper examines the impact of obesity on the prevalence of four doctor-diagnosed chronic diseases in Senegal and South Africa. The results reveal that obese respondents were 4.7, 2.8, and 4.8% more likely to face the risks of arthritis, diabetes, and heart diseases in South Africa and 6.5 and 7.4% more likely to face the risks of heart disease and asthma in Senegal than their lean counterparts. Obesity imposes a real and substantial danger, affecting the prevalence of chronic diseases. Unchecked it can be a major public health problem, impose a serious challenge to the health sector, and can jeopardize future developments.

  14. Does anxiety cause freezing of gait in Parkinson's disease?

    Kaylena A Ehgoetz Martens

    Full Text Available Individuals with Parkinson's disease (PD commonly experience freezing of gait under time constraints, in narrow spaces, and in the dark. One commonality between these different situations is that they may all provoke anxiety, yet anxiety has never been directly examined as a cause of FOG. In this study, virtual reality was used to induce anxiety and evaluate whether it directly causes FOG. Fourteen patients with PD and freezing of gait (Freezers and 17 PD without freezing of gait (Non-Freezers were instructed to walk in two virtual environments: (i across a plank that was located on the ground (LOW, (ii across a plank above a deep pit (HIGH. Multiple synchronized motion capture cameras updated participants' movement through the virtual environment in real-time, while their gait was recorded. Anxiety levels were evaluated after each trial using self-assessment manikins. Freezers performed the experiment on two separate occasions (in their ON and OFF state. Freezers reported higher levels of anxiety compared to Non-Freezers (p < 0.001 and all patients reported greater levels of anxiety when walking across the HIGH plank compared to the LOW (p < 0.001. Freezers experienced significantly more freezing of gait episodes (p = 0.013 and spent a significantly greater percentage of each trial frozen (p = 0.005 when crossing the HIGH plank. This finding was even more pronounced when comparing Freezers in their OFF state. Freezers also had greater step length variability in the HIGH compared to the LOW condition, while the step length variability in Non-Freezers did not change. In conclusion, this was the first study to directly compare freezing of gait in anxious and non-anxious situations. These results present strong evidence that anxiety is an important mechanism underlying freezing of gait and supports the notion that the limbic system may have a profound contribution to freezing in PD.

    Purpose: To determine whether prevalent diabetes mellitus (pDM) affects the presentation, extent of radiotherapy, or prostate cancer (PCa)-specific mortality (PCSM) and whether PCa aggressiveness affects the risk of non-PCSM, DM-related mortality, and all-cause mortality in men with pDM. Methods: Between October 1997 and July 2907, 5,279 men treated at the Chicago Prostate Cancer Center with radiotherapy for PCa were included in the study. Logistic and competing risk regression analyses were performed to assess whether pDM was associated with high-grade PCa, less aggressive radiotherapy, and an increased risk of PCSM. Competing risks and Cox regression analyses were performed to assess whether PCa aggressiveness described by risk group in men with pDM was associated with the risk of non-PCSM, DM-related mortality, and all-cause mortality. Analyses were adjusted for predictors of high-grade PCa and factors that could affect treatment extent and mortality. Results: Men with pDM were more likely (adjusted hazard ratio [AHR], 1.9; 95% confidence interval [CI], 1.3-2.7; p = .002) to present with high-grade PCa but were not treated less aggressively (p = .33) and did not have an increased risk of PCSM (p = .58) compared to men without pDM. Among the men with pDM, high-risk PCa was associated with a greater risk of non-PCSM (AHR, 2.2; 95% CI, 1.1-4.5; p = .035), DM-related mortality (AHR, 5.2; 95% CI, 2.0-14.0; p = .001), and all-cause mortality (AHR, 2.4; 95% CI, 1.2-4.7; p = .01) compared to favorable-risk PCa. Conclusion: Aggressive management of pDM is warranted in men with high-risk PCa.

  16. Waldmann's disease: a rare cause of protein losing enteropathy in an adult patient

    Directory of Open Access Journals (Sweden)

    Cláudio Martins

    Full Text Available Primary intestinal lymphangiectasia or Waldmann's disease is an uncommon cause of protein losing enteropathy with an unknown etiology and is usually diagnosed during childhood. It is characterized by dilation and leakage of intestinal lymph vessels leading to hypoalbuminemia, hypogammaglobulinemia and lymphopenia. Differential diagnosis should include erosive and non-erosive gastrointestinal disorders, conditions involving mesenteric lymphatic obstruction and cardiovascular disorders that increase central venous pressure. Since there are no accurate serological or radiological available tests, enteroscopy with histopathological examination based on intestinal biopsy specimens is currently the gold standard diagnostic modality of intestinal lymphangiectasia. We report a rare case of a primary intestinal lymphangiectasia in a 60-year-old Caucasian female who presented with asymptomatic hypoalbuminemia and hypogammaglobulinemia. After the diagnosis of a protein losing enteropathy, the patient underwent an enteroscopy and biopsies were taken, whose histological examination confirmed dilated intestinal lymphatics with broadened villi of the small bowel. Secondary causes of intestinal lymphangiectasia were excluded and the diagnosis of Waldmann's disease was recorded. The patient was put on a high-protein and low-fat diet with medium-chain triglyceride supplementation with improvement.

    Congenital nasal pyriform aperture stenosis (CNPAS) is a rare cause of newborn airway obstruction. It can be clinically indistinguishable from choanal atresia, which is much more frequent. CT confirms the diagnosis by revealing in detail the anatomical alterations underlying this anomaly. These might or might not occur in association with other alterations. We present 4 cases of CNPAS, all of which presented respiratory distress and clinical symptoms similar to those of choanal atresia in newborn children. The premature diagnosis and a conventional treatment of tube placement in order to keep the airway open, until the pyriform aperture grows large enough to permit normal breathing, resulted in recovery of the patients.

    Linking marine epizootics to a specific aetiology is notoriously difficult. Recent diagnostic successes show that marine disease diagnosis requires both modern, cutting-edge technology (e.g. metagenomics, quantitative real-time PCR) and more classic methods (e.g. transect surveys, histopathology and cell culture). Here, we discuss how this combination of traditional and modern approaches is necessary for rapid and accurate identification of marine diseases, and emphasize how sole reliance on any one technology or technique may lead disease investigations astray. We present diagnostic approaches at different scales, from the macro (environment, community, population and organismal scales) to the micro (tissue, organ, cell and genomic scales). We use disease case studies from a broad range of taxa to illustrate diagnostic successes from combining traditional and modern diagnostic methods. Finally, we recognize the need for increased capacity of centralized databases, networks, data repositories and contingency plans for diagnosis and management of marine disease.

    The advent of HIV infection has significantly changed the distribution of the causes of lymphocytic meningitis. The objective of this study was to identify these causes among persons with HIV hospitalized in the infectious disease department of the CHU of Conakry. This retrospective study examined hospital records of patients with HIV infection admitted for lymphocytic meningitis over a 10-year period. Of the 8649 hospitalizations in the department during the study period, 3167 patients had HIV infection, and 85 of the latter were diagnosed with lymphocytic meningitis. Slightly more than half were male (sex ratio M/F = 1.1). Their mean age was 32 years. Of these 85 patients, 73 were positive for HIV-1 only and 12 for HIV1+2. A CD4 count was performed only in 13/85 patients and averaged 140 cells/mm3. The main causes associated with lymphocytic meningitis were cryptococcosis (58%), toxoplasmosis (5%), and tuberculosis (2%). Streptococcus pneumoniae, Neisseria meningitidis, and Hæmophilus influenzae were also identified in 16% of cases. In 18% of cases no microbe was identified. The overall lethality rate was 68%; it reached 100% for tuberculous meningitis and for the cases without any identified cause and was 75%-76% for the patients with toxoplasmosis and cryptococcosis. The survival rate was 100% for all bacterial causes. A cause for lymphocytic meningitis was identified in more than 81% of the patients in our series, and the most common microbe was Cryptococcus neoformans. A better microbiological technical platform and improved accessibility to treatment would enable us to provide more relevant results and treatment.

  20. Mycoplasma genitalium: An Emerging Cause of Pelvic Inflammatory Disease

    2011-01-01

    Full Text Available Mycoplasma genitalium is a sexually transmitted pathogen that is increasingly identified among women with pelvic inflammatory disease (PID. Although Chlamydia trachomatis and Neisseria gonorrhoeae frequently cause PID, up to 70% of cases have an unidentified etiology. This paper summarizes evidence linking M. genitalium to PID and its long-term reproductive sequelae. Several PCR studies have demonstrated that M. genitalium is associated with PID, independent of gonococcal and chlamydial infection. Most have been cross-sectional, although one prospective investigation suggested that M. genitalium was associated with over a thirteenfold risk of endometritis. Further, a nested case-control posttermination study demonstrated a sixfold increased risk of PID among M. genitalium positive patients. Whether or not M. genitalium upper genital tract infection results in long-term reproductive morbidity is unclear, although tubal factor infertility patients have been found to have elevated M. genitalium antibodies. Several lines of evidence suggest that M. genitalium is likely resistant to many frequently used PID treatment regimens. Correspondingly, M. genitalium has been associated with treatment failure following cefoxitin and doxycycline treatment for clinically suspected PID. Collectively, strong evidence suggests that M. genitalium is associated with PID. Further study of M. genitalium upper genital tract infection diagnosis, treatment and long-term sequelae is warranted.

    A patient with pituitary-dependent hypercortisolism, unresponsive to resection of nodules in the anterior lobe, is described. Histochemical stains of the nodules showed multiple, focal, cellular expansions of the fibrovascular stroma. Transitions between normal and expanded adenohypophysial acini were present. Immunoperoxidase stains for ACTH and other pituitary hormones revealed that these multiple foci contained an excess of ACTH-positive cells. Less than 10% of the cells in these foci were negative for ACTH and positive for other hormones. Serial sections showed that these foci of predominantly ACTH-producing acini were not connected. Clinical, morphological, and immunohistochemical data indicated that ACTH-cell hyperplasia caused Crushing's disease in this patient. Pathologic study of individual cases should concentrate on determining whether hyperplasia or adenoma exist at the time of surgical exploration of the pituitary gland, since this determination is important to proper treatment. Tentative criteria to recognize ACTH-cell hyperplasia are: 1. Multiple foci of ACTH laden cells. 2. A minor subpopulation of cells of alternate hormone series. 3. Expansion without destruction of acini in the adenohypophysis.

    During 1974-1997, the incidence of occupational diseases caused by ionizing radiation in medical personnel was low (0 to 0.4 % of all notified occupational diseases, with a decreasing tendency over this period of time). There have been 136 cases of occupational diseases caused by ionizing radiation; in this, 111 cases occurred in the health care sector. Radiation dermatitis was the most frequent disease (88 cases). Physicians constituted the most affected occupational group in the 1991 - 1997 period. The age of the affected physicians lay in the range of 45 to 77. The personnel affected by radiation dermatitis had the shortest (5 years) as well as longest (46 years) exposure. Lung cancer caused by radioactive chemicals was only diagnosed in two persons in the health care sector during 1974 - 1997. It should be noted that the occupational diseases were caused by elevated exposures experienced in previous years or developed as a consequence of radiation accidents. In view of the present advanced level of protection against ionizing radiation, the numbers of this kind of disease is not expected to grow any further

    One of the more frequent manifestations of diseases of the bile ducts are its’ strictures or stenoses that could be of either malignant or benign nature. Current methods of diagnosing this pathology include computer tomography (CT) scan, magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP). However, these methods are not always informative, which makes this a current and topical problem. A fundamentally new method that broadens the capabilities of ERCP when diagnosing diseases of the bile duct accompanied by the development of strictures or stenoses is probe-based confocal laser endomicroscopy (pCLE). The method is based on the principle of confocal fluorescence microscopy. The most elaborate complications arise with the presence of the pre-existing pancreatobiliary pathology: pseudotumoral chronic pancreatitis, acute cholangitis, etc. Early stage cholangiocarcinoma diagnosis can be difficult (and not always possible) even with the help of modern research methods. For the timely diagnostic it is advantageous to conduct pCLE and targeted biopsy of the zone with most manifested changes. In all instances, the first use of the pCLE method for diagnostic purposes allowed us to clarify and correctly verify the diagnosis. When concerning the diseases of the bile duct, the modern stage of pCLE development can be of critical importance when other methods are not effective. (paper)

    One hundred fifty-four patients referred for coronary arteriography were prospectively studied with stress electrocardiography, stress thallium scintigraphy, cine fluoroscopy (for coronary calcifications), and coronary angiography. Pretest probabilities of coronary disease were determined based on age, sex, and type of chest pain. These and pooled literature values for the conditional probabilities of test results based on disease state were used in Bayes theorem to calculate posttest probabilities of disease. The results of the three noninvasive tests were compared for statistical independence, a necessary condition for their simultaneous use in Bayes theorem. The test results were found to demonstrate pairwise independence in patients with and those without disease. Some dependencies that were observed between the test results and the clinical variables of age and sex were not sufficient to invalidate application of the theorem. Sixty-eight of the study patients had at least one major coronary artery obstruction of greater than 50%. When these patients were divided into low-, intermediate-, and high-probability subgroups according to their pretest probabilities, noninvasive test results analyzed by Bayesian probability analysis appropriately advanced 17 of them by at least one probability subgroup while only seven were moved backward. Of the 76 patients without disease, 34 were appropriately moved into a lower probability subgroup while 10 were incorrectly moved up. We conclude that posttest probabilities calculated from Bayes theorem more accurately classified patients with and without disease than did pretest probabilities, thus demonstrating the utility of the theorem in this application

  10. Historical perspectives on music as a cause of disease.

    Kennaway, James

    2015-01-01

    The relationship between music and medicine is generally understood in the benign context of music therapy, but, as this chapter shows, there is a long parallel history of medical theories that suggest that music can cause real physical and mental illness. During the seventeenth and eighteenth centuries, the idea of music as an expression of universal harmony was challenged by a more mechanistic model of nervous stimulation. By the 1790s, there was a substantial discourse on the dangers of musical overstimulation to health in medicine, literature, and etiquette books. During the nineteenth century, the sense of music as a pathogenic stimulant gained in influence. It was often linked to fears about sexuality, female gynecological health, and theories of hypnosis and degeneration. In the twentieth century, the debate on the medical perils of the wrong kinds of music became overtly politicized in Germany and the Soviet Union. Likewise, the opponents of jazz, particularly in the United States, often turned to medicine to fend off its supposed social, moral, and physical consequences. The Cold War saw an extensive discourse on the idea of musical "brainwashing," that rumbled on into the 1990s. Today, regular media panics about pathological music are mirrored by alarming evidence of the deliberate use of music to harm listeners in the context of the so-called War on Terror. Can music make you ill? Music therapy is a common if perhaps rather neglected part of medicine, but its diametric opposite, the notion that music might lead to real mental and physical illness, may seem improbable. In fact, over the last two hundred years, there have been many times when as much was written about the medical dangers of music as about its potential benefits. Since the eighteenth century, fears about music's effects on the nerves and the mind have created a remarkably extensive discourse on pathological music based on a view of both music and the causation of disease as matters of

    The aim of the study was to identify prognostic factors for weight loss in patients recently diagnosed with mild Alzheimer disease (AD), with special emphasis on the patients' social participation and living arrangements. The data used in this study was part of the Danish Alzheimer Intervention......%. Furthermore, the results suggested a trend that for men, living alone was a risk factor for losing weight, whereas for women living with somebody was associated with a higher risk. However, further studies are pertinent within this area. As weight loss is a predictor of mortality in patients with AD...

    To describe the course of Meniere's disease with noninvasive treatment during the first few years after initial diagnosis. A retrospective review of consecutive patients with newly diagnosed definite Meniere's disease between 2013 and 2016 and a minimum follow-up of 1 year. Patients received a written plan for low sodium, water therapy, and treatment with a diuretic and/or betahistine. Subjects were screened and treated for vestibular migraine as needed. Vertigo control and hearing status at most recent follow-up were assessed. Forty-four subjects had an average follow up of 24.3 months. Thirty-four percent had Meniere's disease and vestibular migraine, and 84% had unilateral Meniere's disease. Seventy-five percent had vertigo well controlled at most recent follow-up, with only noninvasive treatments. Age, gender, body mass index, presence of vestibular migraine, bilateral disease, and duration of follow-up did not predict noninvasive treatment failure. Worse hearing threshold at 250 Hz and lower pure tone average (PTA) at the time of diagnosis did predict failure. Fifty-two percent of ears had improved PTA at most recent visit, 20% had no change, and 28% were worse Conclusions: Encountering excellent vertigo control and stable hearing after a new diagnosis of Meniere's disease is possible with noninvasive treatments. Worse hearing status at diagnosis predicted treatment failure.

    IgG4-related disease is a systemic disease characterized by lesions with IgG4 positive plasma cell infiltration in the involved organs and a raised serum IgG4 level. We report a patient of 70-year-old male presented orbital inflammation of IgG4-related disease. The patient developed right eye pain, double vision, and reduced eye sight. MRI image revealed mild right ocular proptosis and swelling of right carvenous sinus, bilateral intraorbital extraocular muscles and right optic nerve. Right optic nerve showed ring-like enhancement. IgG4-related disease was suspected with increased serum IgG4 level of 355 mg/dl, mediastinal lymphadenopathy and prostate enlargement. Transbronchial lung biopsy and prostate needle biopsy were administered with negative results. The eye related symptoms resolved with time, but serum IgG4 continuously increased. IgG4-related disease was diagnosed by nasal mucosa biopsy, which showed IgG4 positive plasma cells within the inflammatory infiltrate. This report emphasizes the usefulness of nasal mucosa biopsy for the diagnosis of IgG4 related disease with lesions difficult to approach.

    Memory impairment has been proposed as the most common early sign of Alzheimer's disease (AD). The aims of this work were to evaluate the risk of progression from mild memory impairment/no dementia (MMI/ND) to clinically diagnosable AD in a community-based prospective cohort and to establish the risk factors for progression from MMI/ND to AD in the elderly. Elderly subjects aged over 65 years were selected from the participants in the first Nakayama study. MMI/ND was defined as memory deficit on objective memory assessment, without dementia, impairment of general cognitive function, or disability in activities of daily living. A total of 104 MMI/ND subjects selected from 1242 community-dwellers were followed longitudinally for five years. During the five-year follow-up, 11 (10.6%) subjects were diagnosed with AD, five (4.8%) with vascular dementia (VaD), and six (5.8%) with dementia of other etiology. Logistic regression analysis revealed that diabetes mellitus (DM) and a family history of dementia (within third-degree relatives) were positively associated with progression to AD, while no factor was significantly associated with progression to VaD or all types of dementia. DM and a family history of dementia were significant risk factors for progression from MMI/ND to clinically diagnosable AD in the elderly in a Japanese community.

    An advanced driver assistance system (ADAS) provided information about speed limits, speed, speeding, and following distance. Information was presented to the participants by means of a head-up display. Effects of the information on speed and headway control were studied in a longer-term driving simulator study including 12 repeated measures spread out over 4 weeks. Nine healthy older drivers between the ages of 65 and 82 years and 9 drivers between the ages of 68 and 82 years diagnosed with Parkinson's disease (PD) participated in the study. Within the 4 weeks, groups completed 12 consecutive sessions (10 with ADAS and 2 without ADAS) in a driving simulator. Results indicate an effect of ADAS use on performance. Removing ADAS after short-term exposure led to deterioration of performance in all speed measures in the group of drivers diagnosed with PD. These results suggest that provision of traffic information was utilized by drivers diagnosed with PD in order to control their speed.

  18. Cholesteryl ester storage disease: a rare and possibly treatable cause of premature vascular disease and cirrhosis.

    Science.gov (United States)

    Reynolds, Tim

    2013-11-01

    Cholesteryl ester storage disease (CESD) is an autosomal recessive lysosomal storage disorder caused by a variety of mutations of the LIPA gene. These cause reduced activity of lysosomal acid lipase, which results in accumulation of cholesteryl esters in lysosomes. If enzyme activity is very low/absent, presentation is in infancy with failure to thrive, malabsorption, hepatosplenomegaly and rapid early death (Wolman disease). With higher but still low enzyme activity, presentation is later in life with hepatic fibrosis, dyslipidaemia and early atherosclerosis.Identification of this rare disorder is difficult as it is essential to assay leucocyte acid phosphatase activity. An assay using specific inhibitors has now been developed that facilitates measurement in dried blood spots. Treatment of CESD has until now been limited to management of the dyslipidaemia, but this does not influence the liver effects. A new enzyme replacement therapy (Sebelipase) has now been developed that could change treatment options for the future.

    Prolactin is a hormone; in addition to it known roles, it has immunomodulatory effects on lymphocytes maturation and immunoglobulins production. Hyperprolactinemia has been demonstrated in various autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, type I diabetes mellitus, and Graves' disease. In view of the prolactin immunomodulatory roles, studying prolactin levels in pemphigus as an autoimmune blistering disease may introduce new ways of understanding disease etiology and developing treatment strategies. Our purpose was to determine the prolactin levels in patients with newly diagnosed pemphigus vulgaris and study its correlation with pemphigus disease area index. Our study was limited by the lack of a control group. In this cross-sectional study, prolactin and anti-desmoglein 1 and 3 autoantibodies levels were measured in 50 patients with newly diagnosed pemphigus vulgaris in Razi Dermatology Hospital. Pemphigus severity and extent was estimated using the Pemphigus Disease Area Index. Of the 50 patients, 18 were male and 32 were female with a mean age of 41.56 ± 13.66 years. Mean prolactin (PRL) level was 15.60 ± 11.72 ng/ml (10.68 in males and 18.37 in females). Mean anti-desmoglein 1 and 3 autoantibodies were 135.8 ± 119.8 and 245.8 ± 157.4 U/ml, respectively. Eleven out of 50 patients had a higher than normal prolactin range. No relation was found between prolactin level and disease activity ( p = .982). Also, correlation studies show no relation between prolactin and anti-desmoglein 1 and 3 autoantibodies levels (respectively, p = .771 and .738). In comparing the extent of the disease between the two groups with normal and high prolactin, paired t-test showed no significance ( p = .204). In our study, 22% of patients had hyperprolactinemia, which was greater among females. The highest PRL level was detected in mucocutaneous group. Although serum PRL levels were higher in patients with a greater Pemphigus Disease Area Index

    The magnitude of undiagnosed COPD in our population with cardiovascular risk factors (CVRF) is unknown. The objective of this study was to estimate the prevalence of undiagnosed COPD and its specific characteristics in a population with CVRF. Study the prevalence of COPD in patients with CVRF. Spirometry was performed between 01/01/2015 and 12/31/2016 and the percentage of patients with COPD, who had not previously been diagnosed, was determined. Each patient's variables of interest were recorded; the records of patients who had spirometry showing COPD were checked to confirm whether a diagnosis had been recorded or not. The association of undiagnosed COPD with different independent variables was determined with adjusted odds ratio (aOR) by non conditional logistic regression models. 2,295 patients with CVRF were studied. The overall prevalence of COPD was 14.5%. An underdiagnosis of 73.3% was observed. Newly diagnosed COPD vs. undiagnosed COPD showed to be higher in women (74.1% vs. 36.0%; P=.081), non-smokers (21.3% vs. 12.4%; P=.577), mild cases (GOLD1) (42.6% vs. 32.4%, P=.008) and cases with lower than average HbA1c (5.5% vs. 5.6%; P=.008) and uric acid (5.1mg/dL vs. 5.6mg/dL; P=.011). The variables associated with undiagnosed COPD were: women (aOR=1.27; 95%CI: 0.74-2.17; P=.383); age (aOR=0.94; 95%CI: 0.87-0.99; P=.018); smokers (smoker/non-smoker) (aOR=0.47; 95%CI: 0.22-1.01; P=.054) and HbA1c (%) (aOR=0.45; 95%CI: 0.23-0.88; P=.019). The under-diagnosis of COPD is very high. The contact patients aged between 50 and 65 years-old who have CVRF with their health system should be reassessed, and they need to ask for a spirometry.

    Crohn's disease (CD) is a chronic inflammatory condition that plagues millions all over the world. This debilitating bowel disease can start in early childhood and continue into late adulthood. Signs and symptoms are usually many and multiple tests are often required for the diagnosis and confirmation of this disease. However, little is still understood about the cause(s) of CD. As a result, several theories have been proposed over the years. One theory in particular is that Mycobacterium avium subspecies paratuberculosis (MAP) is intimately linked to the etiology of CD. This fastidious bacterium also known to cause Johne's disease in cattle has infected the intestines of animals for years. It is believed that due to the thick, waxy cell wall of MAP it is able to survive the process of pasteurization as well as chemical processes seen in irrigation purification systems. Subsequently meat, dairy products and water serve as key vehicles in the transmission of MAP infection to humans (from farm to fork) who have a genetic predisposition, thus leading to the development of CD. The challenges faced in culturing this bacterium from CD are many. Examples include its extreme slow growth, lack of cell wall, low abundance, and its mycobactin dependency. In this review article, data from 60 studies showing the detection and isolation of MAP by PCR and culture techniques have been reviewed. Although this review may not be 100% comprehensive of all studies, clearly the majority of the studies overwhelmingly and definitively support the role of MAP in at least 30%-50% of CD patients. It is very possible that lack of detection of MAP from some CD patients may be due to the absence of MAP role in these patients. The latter statement is conditional on utilization of methodology appropriate for detection of human MAP strains. Ultimately, stratification of CD and inflammatory bowel disease patients for the presence or absence of MAP is necessary for appropriate and effective

    The whole spectrum of disorders of the hematopoietic tissue, eye and skin induced by ionizing radiation covers complex pathologies termed as a postirradiation syndrome, as well as various malignancies. The aim of this work is to present the data on incidence of occupational diseases with ionizing radiation as a causative agent. The work is based on the data compiled from "Occupational Diseases Reporting Forms" for the years 1971-2006 collected in the Central Register of Occupational Diseases. The incidence of certified occupational diseases with ionizing radiation as a causative agent is expressed in absolute numbers and the rate per 100 000 employees. The data comprise information on disease entities, gender, age, exposure duration and the branch of national economy. In total, 599 diseases (0.2% of all occupational diseases) were diagnosed as those induced by ionizong radiation. Annual incidence rates per 100,000 employees fell within the range of 0.0-0.7. Miners formed the major (51.9%) occupational group affected by ionizing radiation. They were followed by health care (34.3%) and construction (6.4%) workers. Cancers made over 50% of pathologies located at 28 sites. These included cancers of lung (59.2%), skin (10.0%) and hematopoietic tissue (8.7%). Almost all (99.35) diseases recorded in the mining industry were cancers. Non-cancer diseases were more frequent in health care workers, among them postradiation cataract occupied the first place. A great deal of reported cancer sites give rise to controversy in terms of the cause-effect association with ionizing radiation exposure and also due to incomplete data on exposure level. Postradiation cancers among health care workers have not been registered over recent years, which means that occupational exposure surveillance carried out for many years proves to be effective. Distant effects of exposure to ionizing radiation, revealed in workers of no longer existing uranium mine, appeared to be a particular problem

    2009-04-01

    Encephalopathy due to hepatic or renal failure, electrolyte disturbances, or the administration of benzodiazepines and narcotics is commonly encountered, well reviewed in the literature, and, therefore, not usually missed. This article focuses on encephalopathies that were previously well described but may be overlooked by modern clinicians, as well as those that are still taught in the classroom but seldom thought of in practice. Due to the presumed relative rarity of these cases and emphasis on the well-memorized "classic" clinical presentations, these often treatable, and perhaps not so rare, encephalopathies due to systemic medical illness may go undiagnosed and untreated. Pancreatic encephalopathy, Wernicke's encephalopathy, and pellagra encephalopathy are reviewed in detail; cefepime and ifosfamide encephalopathies are discussed as examples of specific medication-induced encephalopathies. Septic encephalopathy, central pontine myelinolysis, and fat embolism syndrome are briefly reviewed. The encephalopathies reviewed have the potential for devastating neurological consequences if recognition and, therefore, treatment are delayed. Clinical improvement for many of these syndromes depends on prompt intervention. This article highlights some representative examples of less-commonly diagnosed metabolic and toxic encephalopathies.

    This study aimed to evaluate the left ventricular (LV) functions in a cohort of children with Graves' disease (GD). This is a cross-sectional case-control study. It included 36 children with GD and 36 healthy children matched for age and gender. Thyroid hormones (TSH, FT4, and FT3) and anti-thyroid autoantibodies [anti-thyroid peroxidase (anti-TPO), thyrotropin receptor (TRAbs), and thyroglobulin antibodies] were measured. Conventional and tissue Doppler imaging (TDI) echocardiographies were used to assess left ventricular systolic and diastolic functions. LV mass index (LVMI) and myocardial performance index (MPI) were also measured. Compared to healthy children, conventional echocardiography of patients with GD revealed higher LVMI (P = 0.001) indicating LV hypertrophy but normal LV functions while TDI revealed lower Em/Am ratio indicating LV diastolic dysfunction (P = 0.001). Significant correlations were reported between FT4 with LVMI (P = 0.05), Em/Am (P = 0.01), and MPI (P = 0.01). In multivariate analysis, a positive correlation was identified between FT4 with MPI (OR = 1.17; 95% CI = 1.09-1.15; P = 0.001). Children with newly diagnosed GD may have significant subclinical changes in LV structure and function (diastolic and global). TDI is more sensitive than conventional Doppler in detecting LV dysfunction. These findings highlight the importance of early monitoring of children with GD for left ventricular mass index and diastolic function. What is Known: • There is an increased risk for cardiac abnormalities in children with Graves' disease (GD). • Limited studies assessed left ventricular function in patients with GD. What is New: • Children with newly diagnosed GD may have significant subclinical changes in left ventricular structure and functions. • Children with newly diagnosed GD should be monitored for left ventricular mass index and diastolic function.

    Celiac disease (CD) is a difficult-to-diagnose condition because of its multiple clinical presentations and symptoms shared with other diseases. Gold-standard diagnostic confirmation of suspected CD is achieved by biopsying the small intestine. To develop a clinical decision-support system (CDSS) integrated with an automated classifier to recognize CD cases, by selecting from experimental models developed using intelligence artificial techniques. A web-based system was designed for constructing a retrospective database that included 178 clinical cases for training. Tests were run on 270 automated classifiers available in Weka 3.6.1 using five artificial intelligence techniques, namely decision trees, Bayesian inference, k-nearest neighbor algorithm, support vector machines and artificial neural networks. The parameters evaluated were accuracy, sensitivity, specificity and area under the ROC curve (AUC). AUC was used as a criterion for selecting the CDSS algorithm. A testing database was constructed including 38 clinical CD cases for CDSS evaluation. The diagnoses suggested by CDSS were compared with those made by physicians during patient consultations. The most accurate method during the training phase was the averaged one-dependence estimator (AODE) algorithm (a Bayesian classifier), which showed accuracy 80.0%, sensitivity 0.78, specificity 0.80 and AUC 0.84. This classifier was integrated into the web-based decision-support system. The gold-standard validation of CDSS achieved accuracy of 84.2% and k=0.68 (pdiagnosis.

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

    Skin diseases are a common reason for consulting a GP. This regular occurrence happens despite most GPs' lack of knowledge and training in skin disease. We aimed to explore different diagnostic approaches of GPs in patients presenting with a dermatological problem. In addition, we aimed to identify strategies used by GPs to handle diagnostic uncertainty in these patients. We conducted interviews (20-40 minutes) with 14 GPs using a semi-structured guideline. Recalling encounters with patients with skin disease, GPs described their individual diagnostic strategies. Interviews were taped and transcribed verbatim. Qualitative analysis was conducted by two independent raters using a deductive-inductive approach. We identified several aspects of a complex decision-making process in GPs' diagnostic management of patients with dermatological problems. In the general diagnostic workup, GPs used a broad spectrum of different strategies such as spot diagnosis, stepwise refinement, pattern recognition trigger or test of treatment. GPs reduced diagnostic uncertainty through the identification of red flags, the application of the test of time, therapeutic trials and asking for further advice, including patient referral. GPs encounter a broad range of dermatological problems in their daily work using a variety of strategies in the workup of these patients. However, in a significant number of patients, there remains diagnostic uncertainty that is mainly reduced by specialist referral. Regular training in the diagnosis and treatment of common dermatological diseases should be offered to all GPs. © The Author 2015. Published by Oxford University Press. All rights reserved.

    2015-01-01

    INTRODUCTION: Only few studies have systematically investigated neuropsychiatric aspects in patients with Cushing's disease (CD). Pain syndromes have been described in patients with pituitary adenomas, but so far no systematical investigation has been conducted in patients with CD. Additionally, CD has an association with cardiometabolic comorbidities which ultimately leads to increased morbidity and mortality. Long-term treatment of the hypercortisolic state cannot prevent the persistence of...

    Faisalabad is third most populous and industrial city, known as Manchester of Pakistan. Most of the people working in the industries of this city are exposed to highly polluted and toxic environment. Lead is a natural metal found in the environment and its contamination exceeds the range of normal limits by human activities causing a lot of health hazardous. An effort is made to assess the association of anemia and cholesterol with the development IHD among industrial workers who are exposed to the lead polluted environment. For this purpose the study was conducted during a period of one year (2006-7) and the respondents were the patients from industrial area coming to the hospitals visiting at DHQ Hospital Faisalabad. Only those patients were selected for this study who were diagnosed with clinical symptoms of lead toxicity. The demographic features of the respondents regarding their age, gender, marital status, family size, education, income, duration on job, working place and nature of work were considered. The data of this study was categorical nature and this measures the association among exposure to the environment with lead toxicity and causative risk factors i.e., cholesterol level, Hb level (anemia) causing ischemic heart disease (IHD) were studied.

    Full Text Available Introduction: Kimura’s disease (KD is an allergic inflammatory disorder of unknown etiology endemic in Orientals. Kimura’s disease was first mentioned by Kimm and Szeto in China in 1937. Kimura’s disease is commonly encountered in Asia and is mostly reported in Japan, China, Singapore and Honkong. However, only a few cases have been reported in the Indian subcontinent. Case Report: A case of Kimura’s disease in a young male managed by surgery is reported in addition to a literature review. Conclusion: Diagnosis is made on the basis of histopathological analysis, clinical presentation, and laboratory investigations. Long term follow-up is required as Kimura’s disease is prone for recurrence.

    Bruton's agammaglobulinemia is a primary immunodeficiency with a disease onset during the first months of age, when the maternal serum immunoglobulin levels decrease. It is characterized by recurrent infections and agammaglobulinemia. We report the case of a 6-year-old male patient with third-degree consanguinity, product of a third pregnancy and complete immunization scheme. He had a history of oral candidiasis at the age of 3 months, chicken pox at the age of 7 months, and two episodes of complicated bronchopneumonia at the age of 1 year and 6 years. He was admitted to the hospital because of fever and cough. Examination of the chest showed rales and right basilar hypoventilation, and a blood cell count revealed leukocytosis and neutrophilia. The diagnosis of pneumonia was made. He was treated with IV antibiotics. Serum immunoglobulins were reported to be low (IgM 55 mg/dL, IgA 0.9 mg/dL, and IgG 199 mg/dL). With these findings the clinical diagnosis of X-linked agammaglobulinemia (ALX) was concluded. A molecular test was performed fining a BTK gene confirming the diagnosis of Bruton's disease. Therapy with intravenous IgG was started every 21 days. During his evolution, he presented three episodes of rhinosinusitis, one of suppurative otitis media, and four events of pneumonia that required 37 days of hospitalization. After hospital discharge, the patient was free of infections and he returned to his daily activities. In cases of recurrent and severe respiratory infections in children, we must consider primary immunodeficiency disease in the differential diagnosis, mainly antibiotic deficiency. Early diagnosis and treatment improves the survival and quality of life in these patients.

    Full Text Available BACKGROUND: Obstructive sleep apnea syndrome (OSAS is a highly prevalent sleep-related disorder that is associated with increased risk of hypertension (HTN and coronary heart disease. This study aimed to evaluate the correlation between the OSAS and coronary artery disease (CAD severity. METHODS: The cross-sectional study was conducted from September 2012 to December 2013. We enrolled 127 patients with chronic stable angina who were referred for coronary angiographic studies in Shahid Chamran and Nour Hospitals in Isfahan, Iran. The Berlin questionnaire (BQ was used for estimate the probability of OSAS in patients as a low or high probability. Demographic characteristics and metabolic risk factors including diabetes mellitus, HTN, obesity, and smoking also were recorded. The severity of CAD was assessed and compared based on the Gensini score with Mann–Whitney U statistical test. Independent t-test for continuous variables and chi-square test for categorical variables were used. RESULTS: Totally, 65.4% of subjects were considered as high and 34.6% as low probability for OSAS, which 81.1% of them had CAD. There was a significant difference between body mass index, systolic blood pressure, diastolic blood pressure, and ischemic heart disease drug consumption with OSAS probability (P < 0.0500. CAD was accompanied by OSAS significantly (P = 0.0260. The Gensini score was significantly higher in patients with high OSAS probability (100.4 ± 69.1 vs. 65.3 ± 68.9; P = 0.0030. OSAS also increase odds of CAD based on regression analysis (odds ratio, 95% confidence interval = 2.7. CONCLUSION: This study indicates that more severe CAD is associated with high OSAS probability identified by BQ.

    Background Celiac disease (CD) is a difficult-to-diagnose condition because of its multiple clinical presentations and symptoms shared with other diseases. Gold-standard diagnostic confirmation of suspected CD is achieved by biopsying the small intestine. Objective To develop a clinical decision–support system (CDSS) integrated with an automated classifier to recognize CD cases, by selecting from experimental models developed using intelligence artificial techniques. Methods A web-based system was designed for constructing a retrospective database that included 178 clinical cases for training. Tests were run on 270 automated classifiers available in Weka 3.6.1 using five artificial intelligence techniques, namely decision trees, Bayesian inference, k-nearest neighbor algorithm, support vector machines and artificial neural networks. The parameters evaluated were accuracy, sensitivity, specificity and area under the ROC curve (AUC). AUC was used as a criterion for selecting the CDSS algorithm. A testing database was constructed including 38 clinical CD cases for CDSS evaluation. The diagnoses suggested by CDSS were compared with those made by physicians during patient consultations. Results The most accurate method during the training phase was the averaged one-dependence estimator (AODE) algorithm (a Bayesian classifier), which showed accuracy 80.0%, sensitivity 0.78, specificity 0.80 and AUC 0.84. This classifier was integrated into the web-based decision–support system. The gold-standard validation of CDSS achieved accuracy of 84.2% and k = 0.68 (p < 0.0001) with good agreement. The same accuracy was achieved in the comparison between the physician’s diagnostic impression and the gold standard k = 0. 64 (p < 0.0001). There was moderate agreement between the physician’s diagnostic impression and CDSS k = 0.46 (p = 0.0008). Conclusions The study results suggest that CDSS could be used to help in diagnosing CD, since the algorithm tested achieved excellent

    Colorectal neoplasm and coronary artery disease (CAD) share similar risk factors, and their co-occurrence may be associated. To investigate the prevalence of colorectal neoplasm in patients with CAD in a cross-sectional study and to identify the predisposing factors for the association of the 2 diseases. Patients in Hong Kong, China, were recruited for screening colonoscopy after undergoing coronary angiography for suspected CAD during November 2004 to June 2006. Presence of CAD (n = 206) was defined as at least 50% diameter stenosis in any 1 of the major coronary arteries; otherwise, patients were considered CAD-negative (n = 208). An age- and sex-matched control group was recruited from the general population (n = 207). Patients were excluded for use of aspirin or statins, personal history of colonic disease, or colonoscopy in the past 10 years. The prevalence of colorectal neoplasm in CAD-positive, CAD-negative, and general population participants was determined. Bivariate logistic regression was performed to study the association between colorectal neoplasm and CAD and to identify risk factors for the association of the 2 diseases after adjusting for age and sex. The prevalence of colorectal neoplasm in the CAD-positive, CAD-negative, and general population groups was 34.0%, 18.8%, and 20.8% (P < .001 by chi2 test), prevalence of advanced lesions was 18.4%, 8.7%, and 5.8% (P < .001), and prevalence of cancer was 4.4%, 0.5%, and 1.4% (P = .02), respectively. Fifty percent of the cancers in CAD-positive participants were early stage. After adjusting for age and sex, an association still existed between colorectal neoplasm and presence of CAD (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.25-2.70; P = .002) and between advanced lesions and presence of CAD (OR, 2.51; 95% CI, 1.43-4.35; P = .001). The metabolic syndrome (OR, 5.99; 95% CI, 1.43-27.94; P = .02) and history of smoking (OR, 4.74; 95% CI, 1.38-18.92; P = .02) were independent factors for the

    A growing interest in posttraumatic growth among individuals who have experienced a traumatic event has given rise to measures such as the Posttraumatic Growth Inventory (PTGI; Tedeschi and Calhoun, 1996). However, such measures may not fully represent all dimensions of change among individuals diagnosed with a chronic disease and fail to highlight the negative changes that may also occur. This study explores the positive and negative changes patients with inflammatory bowel disease (IBD) have experienced since diagnosis. Three hundred and seventy-eight IBD patients provided answers to the qualitative question "Could you please describe the (positive/negative) effect(s) IBD has had on your life?" A grounded theory approach using NVivo was performed on participants' responses. Nearly 73 % of participants reported their disease positively affected their life in some way, and five themes related to positive changes emerged from the analysis: Interpersonal Relations, Personal Growth, Valuing Life, New Life Paths, and Spiritual Growth. However, almost 80 % of participants also reported their disease negatively affected their lives, with three themes emerging from the analysis: Freedom Restrictions, Psychological Side Effects, and Social Isolation. Our results support previous findings but also reveal that some dimensions related to the positive changes following adversity are not adequately assessed by the PTGI (e.g., appraising existing friendships, openness to try different forms of treatment or therapies, and psychological preparedness). The implications of these findings for future measurement and research of posttraumatic growth with IBD patients are discussed.

    Two patients had interhemispheric subdural hematoma (ISH) without clinical signs or symptoms characteristic of ISH. The first patient, a 74-year-old woman with 7 years' history of Parkinson's disease, complained of unresponsiveness and akinesia. The treatment for suspected worsening of the disease failed to improve her conditions. Computed tomography (CT) showed hyperdensity along the falx from the frontal falx over the tentorium. Subsequent CT on the 23rd hospital day showed disappearance of hyperdensity, confirming ISH. The second patient, a 76-year-old woman with multiple cerebral infarction, was referred for loss of consciousness and vomiting. Neurological examination failed to reveal additional or augmented neurological deficits. Computed tomography showed a right parasagittal thin crescent hyperdensity with a flat medial border and a convex lateral border, extending from the anterior falx to the mid-falx. The hyperdensity disappeared on the 47th hospital day. These findings suggest the usefulness of CT as the only procedure when ISH features are not seen. (Namekawa, K.).

    The excellent spatial resolution of myocardial stress perfusion magnetic resonance imaging is effective for the diagnosis of ischemic heart disease. When dipyridamole or adenosine triphosphate is used as a pharmacological stress in cardiac MRI, non-magnetic instruments are required for infusion of these drugs in a MRI room. We attempted to use nicorandil as a pharmacological stressor. Nicorandil exhibited KATP channel opening and nitrate effects, and could be infused without any special instruments. Based on the coronary artery stenosis assessed by coronary angiography, according to the criteria of the American Heart Association (AHA), the sensitivity, specificity and diagnostic accuracy of nicorandil perfusion MRI for the detection of coronary artery stenosis was 85%, 57% and 74.3%, respectively. No major side effects were observed, except for mild hypotension (mean 10 mmHg) after infusion of the drug. It was concluded that myocardial perfusion MRI examination using nicorandil could be performed non-invasively and safely for the evaluation of coronary vessel disease in patients. (author)

  4. Incidence of End-Stage Renal Disease Attributed to Diabetes Among Persons with Diagnosed Diabetes - United States and Puerto Rico, 2000-2014.

    During 2014, 120,000 persons in the United States and Puerto Rico began treatment for end-stage renal disease (ESRD) (i.e., kidney failure requiring dialysis or transplantation) (1). Among these persons, 44% (approximately 53,000 persons) had diabetes listed as the primary cause of ESRD (ESRD-D) (1). Although the number of persons initiating ESRD-D treatment each year has increased since 1980 (1,2), the ESRD-D incidence rate among persons with diagnosed diabetes has declined since the mid-1990s (2,3). To determine whether ESRD-D incidence has continued to decline in the United States overall and in each state, the District of Columbia (DC), and Puerto Rico, CDC analyzed 2000-2014 data from the U.S. Renal Data System and the Behavioral Risk Factor Surveillance System. During that period, the age-standardized ESRD-D incidence among persons with diagnosed diabetes declined from 260.2 to 173.9 per 100,000 diabetic population (33%), and declined significantly in most states, DC, and Puerto Rico. No state experienced an increase in ESRD-D incidence rates. Continued awareness of risk factors for kidney failure and interventions to improve diabetes care might sustain and improve these trends.

    Exaggerated oxidative stress (OS) is usually considered as a disturbance in regular function of an organism. The excessive levels of OS mediators may lead to major damage within the organism's cells and tissues. Therefore, the OS-associated biomarkers may be considered as new diagnostic tools of various diseases. In nephrology, researchers are looking for alternative methods replacing the renal biopsy in patients with suspicion of chronic kidney disease (CKD). Currently, CKD is a frequent health problem in world population, which can lead to progressive loss of kidney function and eventually to end-stage renal disease. The course of CKD depends on the primary disease. It is assumed that one of the factors influencing the course of CKD might be OS. In the current work, we review whether monitoring the OS-associated biomarkers in nephrology patients can support the decision-making process regarding diagnosis, prognostication and treatment initiation.

    BACKGROUND: The effectiveness of beta-blockers for preventing cardiac events has been questioned for patients who have coronary heart disease (CHD) without a prior myocardial infarction (MI). OBJECTIVES: The purpose of this study was to assess the association of beta-blockers with outcomes among...... patients with new-onset CHD. METHODS: We studied consecutive patients discharged after the first CHD event (acute coronary syndrome or coronary revascularization) between 2000 and 2008 in an integrated healthcare delivery system who did not use beta-blockers in the year before entry. We used time......-varying Cox regression models to determine the hazard ratio (HR) associated with beta-blocker treatment and used treatment-by-covariate interaction tests (pint) to determine whether the association differed for patients with or without a recent MI. RESULTS: A total of 26,793 patients were included, 19...

    1985-01-01

    The authors report on two woman patients with confirmed Wilson's desease (hepatolenticular degeneration) who had neurological deficits and showed typical changes evident from laboratory data. Both computed tomography and magnetic resonance tomography revealed degenerative changes in the basal ganglia, especially of the lenticular nucleus, MR showing these defects more clearly than CT. There was a noticeable symmetrical enhancement of signals in the lenticular nucleus which was particularly evident on the image basing on the T 2 (spin-spin relaxation time constant) values. MR could be superior to CT with regard to showing up pathological changes in the basal ganglia. The future indication of MR could be the establishment of an exact correlation between clinical signs and symptoms on the one hand, and morphological findings on the other. Over and above this, it should be explored to what extent MR can already detect degenerative changes in the brain in primarily hepatic types of the disease even without prior neurological examination.

    2015-03-01

    Full Text Available Identification of antinuclear antibodies has been used for the diagnosis of connective tissue diseases for more than fifty years. Indirect immunofluorescence on human epithelial (HEp-2 cells is considered the gold standard screening method for the detection of antinuclear autoantibodies. As the demand of ANA testing increased, the need for automation and standardization has also come forth. A high level of false positive and false negative cases is seen in various populations making it difficult to take clinical decisions. Newer technologies were introduced for the antibody detection to ensure high sensitivity and specificity. This article intends to provide an overview of the concepts on ANA testing, the different diagnostic methods available, the various patterns and clinical utility, the clinical guidelines to be followed, the drawbacks and what lies ahead in the future of ANA testing.Journal of Pathology of Nepal (2015 Vol. 5, 766-773

    Serum pepsinogens I and II (PGI, PGII) levels were determined by PGI and PGII-RIA kits in 84 healthy controls and 128 patients of gastric diseases including 42 patients with gastric cancer. The results showed peptic ulcer cases had elevated PGI and PGII levels. The atrophic gastritis cases had low PGI levels and the gastric cancer cases had low PGI and low PGI/PGII ratio. Using the cut-off values of PGI<35 μg/L and PGI/PGII<1.5 for clinical purpose, the sensitivity and specificity of the test for gastric cancer was 73% and 78%, respectively. Combined with endoscope examination, the serum PGI and PGII levels are valuable for the early diagnosis of gastric cancer

    A 7'3" basketball player was noted to have 2 to 3 times thicker tissue in his hands than 6'10" players by an endocrinologist sitting 10 rows above the player in a basketball arena. This led to the diagnosis of pituitary gigantism where the history revealed that he was 7'3" at 15 years of age. At age 19 when the acryl enlargement was noted, a diagnostic workup revealed elevated growth hormones and insulin-like growth factor 1 (IGF-1) with a 2 × 1.3 cm pituitary tumor. His history suggested that his epiphyseal plates had closed at age 15, and because he continued to produce IGF-1, he now has acromegaly. His elevated adrenocorticotropic hormone (ACTH) before surgery suggests that he also had preclinical Cushing's disease. After pituitary transsphenoidal surgery, all acryl enlargement in hands and ligaments disappeared. His growth hormone, IGF-1 and ACTH returned to normal 2 weeks after surgery.

    was 65.2 years. Urinary glucose concentration (UGC) was determined quantitatively in a freshly voided morning urine specimen. RESULTS: The over-all prevalence of peripheral vascular disease (PVD) was 16.5%. Bivariately, high values of UGC were associated with low prevalence of PVD (p...). The predictive value of PVD--together with HbA1c, glomerular filtration rate (GFR) and 10 other possible predictors--was confirmed in a logistic regression analysis with glycosuria (Y/N) as outcome variable (p=0.0004). CONCLUSION: Surprisingly, type 2 diabetic patients with PVD tend not to have glycosuria...... as compared to patients without PVD. PVD may be indicative of generalized atherosclerotic lesions in the major vessels, including the renal arteries. This could lead to a lowering of GFR and thereby of the amount of glucose filtered. Assuming no, or only a minor direct effect of PVD on tubular function...

    Yellow fever is endemic in some countries. The anti-yellow fever vaccine is the only effective means of protection but is contraindicated for immunocompromised patients. The aim of this paper was to report on a case series of rheumatological patients who were using immunosuppressors and were vaccinated against this disease. This was a retrospective study by means of a questionnaire applied to these patients, who were vaccinated 60 days before the investigation. Seventy patients of mean age 46 years were evaluated. Most of them were female (90%). There were cases of rheumatoid arthritis (54), systemic lupus erythematosus (11), spondyloarthropathy (5) and systemic sclerosis (2). The therapeutic schemes included methotrexate (42), corticosteroids (22), sulfasalazine (26), leflunomide (18), cyclophosphamide (3) and immunobiological agents (9). Sixteen patients (22.5%) reported some minor adverse effect. Among the eight patients using immunobiological agents, only one presented a mild adverse effect. Among these patients using immunosuppressors, adverse reactions were no more frequent than among immunocompetent individuals. This is the first study on this topic.

    The implementation of clinical-decision support algorithms for medical imaging faces challenges with reliability and interpretability. Here, we establish a diagnostic tool based on a deep-learning framework for the screening of patients with common treatable blinding retinal diseases. Our framework utilizes transfer learning, which trains a neural network with a fraction of the data of conventional approaches. Applying this approach to a dataset of optical coherence tomography images, we demonstrate performance comparable to that of human experts in classifying age-related macular degeneration and diabetic macular edema. We also provide a more transparent and interpretable diagnosis by highlighting the regions recognized by the neural network. We further demonstrate the general applicability of our AI system for diagnosis of pediatric pneumonia using chest X-ray images. This tool may ultimately aid in expediting the diagnosis and referral of these treatable conditions, thereby facilitating earlier treatment, resulting in improved clinical outcomes. VIDEO ABSTRACT.

    2017-06-01

    Full Text Available In a lung ultrasound examination, interstitial lung lesions are visible as numerous B-line artifacts, and are best recorded with the use of a convex probe. Interstitial lung lesions may result from many conditions, including cardiogenic pulmonary oedema, non-cardiogenic pulmonary oedema, or interstitial lung disease. Hence difficulties in the differential diagnostics of the above clinical conditions. This article presents cases of patients suffering from interstitial lung lesions discovered in the course of lung ultrasound examination. The patients were examined with a 3.5–5.0 MHz convex probe and a 7.0–11.0 MHz linear probe. Ultrasound images have been analysed, and differences in the imaging with both probes in patients with interstitial lung lesions have been detailed. The use of a linear probe in patients with interstitial lung lesions (discovered with a convex or a micro-convex probe provides additional information on the source of the origin of the lesions.

    Full Text Available Hypothalamic obesity is often complicated in patients with craniopharyngioma due to hypothalamic damage by the tumor itself, treatment modalities, and associated multiple pituitary hormone deficiency. Hypothalamic obesity causes secondary diseases such as nonalcoholic fatty liver disease (NAFLD and diabetes mellitus (DM. We report a 19-year-old female who was diagnosed with craniopharyngioma, developed hypothalamic obesity after tumor resection, and progressed to hepatopulmonary syndrome. She manifested NAFLD 1 year after tumor resection. Two years later, the craniopharyngioma recurred, and she underwent a second resection. Three years after her second operation, she was diagnosed with type 2 DM, after which she did not visit the outpatient clinic for 2 years and then suddenly reappeared with a weight loss of 25.8 kg that had occurred over 21 months. One month later, she presented to the Emergency Department with dyspnea. Laboratory findings revealed liver dysfunction and hypoxia with increased alveolar artery oxygen gradient. Liver biopsy showed portal hypertension and micronodular cirrhosis. Echocardiography and a lung perfusion scan demonstrated a right to left shunt. She was finally diagnosed with hepatopulmonary syndrome and is currently awaiting a donor for liver transplantation. Patients surviving craniopharyngioma need to be followed up carefully to detect signs of hypothalamic obesity and monitored for the development of other comorbidities such as DM, NAFLD, and hepatopulmonary syndrome.

    activation associated with memory encoding. This study demonstrates that neurocognitive deficits are common even in recently diagnosed patients with Parkinson’s disease, and that the associated regional brain activations are influenced by genotype. These data further support the dual syndrome hypothesis of cognitive change in Parkinson’s disease. Longitudinal data will confirm the extent to which these early neurocognitive changes, and their genetic factors, influence the long-term risk of dementia in Parkinson’s disease. The combination of genetics and functional neuroimaging provides a potentially useful method for stratification and identification of candidate markers, in future clinical trials against cognitive decline in Parkinson’s disease.

    2011-01-01

    The purpose of this three-group quasi-experimental research study was to describe the relationship between hemodialysis knowledge and perceived medical adherence to a prescribed treatment regimen in African Americans diagnosed with end stage renal disease and to determine if an educational intervention improved hemodialysis knowledge and medical adherence. Eighty-five African Americans participated in this study using the Life Options Hemodialysis Knowledge Test and the Medical Outcomes Study Measures of Patient Adherence tools. No significant correlation was found between hemodialysis knowledge and medical adherence. Paired sample t-tests revealed significantly higher hemodialysis knowledge scores in the post-test group compared to the pre-test group, t(26) = -3.79, p adherence. This study suggests that more education is needed to improve the knowledge level of African-American patients on hemodialysis.

    Full Text Available Objective. Several tests are available in the diagnostics of sporadic Creutzfeldt-Jakob disease (sCJD; however, none of these is conclusive. We review the values of these tests, from an intensive care unit (ICU perspective. Methods. Case report and review of the literature. Results. A 53-year-old woman initially presenting with psychiatric symptoms developed myoclonus and was admitted 1 month later to the ICU with a suspected nonconvulsive status epilepticus and respiratory insufficiency, probably due to extensive antiepileptic drug therapy. Typical MRI and EEG findings and a positive 14-3-3 protein led to the diagnosis of sCJD. All treatments were terminated, and autopsy confirmed sCJD. Conclusions. Clinical signs combined with MRI, EEG, and 14-3-3 and/or tau protein determination might be sufficient to diagnose or exclude sCJD and may therefore prevent the application of unnecessary diagnostic tests.

    To compare the multidetector CT (MDCT) features of malignant pleural mesothelioma (MPM) and metastatic pleural disease (MPD). The authors reviewed the MDCT images of 167 patients, 103 patients with MPM and 64 patients with MPD. All 167 cases were pathologically confirmed by sonography-guided needle biopsy of pleura, thoracoscopic pleural biopsy, or open thoracotomy. CT features were evaluated with respect to pleural effusion, pleural thickening, invasion of other organs, lung abnormality, lymphadenopathy, mediastinal shifting, thoracic volume decrease, asbestosis, and the presence of pleural plaque. Pleural thickening was the most common CT finding in MPM (96.1%) and MPD (93.8%). Circumferential pleural thickening (31.1% vs. 10.9%, odds ratio [OR] 3.670), thickening of fissural pleura (83.5% vs. 67.2%, OR 2.471), thickening of diaphragmatic pleura (90.3% vs. 73.4%, OR 3.364), pleural mass (38.8% vs. 23.4%, OR 2.074), pericardial involvement (56.3% vs. 20.3%, OR 5.056), and pleural plaque (66.0% vs. 21.9%, OR 6.939) were more frequently seen in MPM than in MPD. On the other hand, nodular pleural thickening (59.2% vs. 76.6%, OR 0.445), hilar lymph node metastasis (5.8% vs. 20.3%, OR 0.243), mediastinal lymph node metastasis (10.7% vs. 37.5%, OR 0.199), and hematogenous lung metastasis (9.7% vs. 29.2%, OR 0.261) were less frequent in MPM than in MPD. When we analyzed MPD from extrathoracic malignancy (EMPD) separately and compared them to MPM, circumferential pleural thickening, thickening of interlobar fissure, pericardial involvement and presence of pleural plaque were significant findings indicating MPM than EMPD. MPM had significantly lower occurrence of hematogenous lung metastasis, as compared with EMPD. Awareness of frequent and infrequent CT findings could aid in distinguishing MPM from MPD.

    Steatosis in patients with nonalcoholic fatty liver disease (NAFLD) is often benign, but may progress to fibrosis. The accurate diagnosis of hepatic steatosis is therefore important for clinical decision-making and prognostic assessments. The controlled attenuation parameter (CAP), a noninvasive measurement obtained with Fibro-Scan, has been developed for liver steatosis assessment. CAP performs poorly in patients with high BMI. The XL probe was initially developed for measuring liver stiffness in overweight patients. We assessed the diagnostic value of CAP in candidates for bariatric surgery with suspected NAFLD examined with the XL probe. For the retrospective group, raw ultrasonic radiofrequency signals were stored prospectively in the Fibro-Scan examination file for offline CAP calculation in 194 consecutive obese patients undergoing liver stiffness measurement in the 15 days before liver biopsy. For the prospective group, CAP was calculated automatically and prospectively from the XL probe in 123 obese patients. In the retrospective group, the diagnostic accuracy of CAP was satisfactory for differentiating S3 from S0-S1-S2 (0.79±0.03; 95% confidence interval: 0.71-0.84) and S3 from S0 (0.85±0.05; 95% confidence interval: 0.73-0.92). The Obuchowski measure demonstrated a very good discriminatory performance: 0.87±0.02 in the retrospective group and 0.91±0.02 in the prospective group. CAP calculations from XL probe measurements efficiently detected severe steatosis in morbidly obese patients with suspected NAFLD. However, the cutoff values should now be confirmed in a larger prospective cohort.

    The aim of the present study was to investigate the diagnostic value of the N-terminal B-type natriuretic peptide (NT-proBNP) in acute Kawasaki disease (KD) given that the clinical criteria and the current basic laboratory tests lack the necessary specificity for accurate diagnosis. Basic biological tests and serum NT-proBNP levels obtained from acute KD patients were compared to that of febrile controls. NT-proBNP was considered abnormal based on the following definitions: above a cut-off determined on receiver operator characteristic (ROC) analysis, above the upper limit for age, or above 2 SD calculated from healthy children. Analyses were also performed for KD cases with complete or incomplete criteria combined and separately. There were 81 patients and 49 controls aged 3.60 ± 2.77 versus 4.25 ± 3.88 years (P= 0.69). ROC analysis yielded significant area under the curve for NT-proBNP. The sensitivity, specificity, positive and negative predictive values were 70.4-88.9%, 69.4-91.8%, 82.8-93.4%, and 65.2-79.1%. The odds ratios based on NT-proBNP definitions varied between 18.13 (95% confidence interval [CI]: 7.21-45.57), 20.82 (95%CI: 8.18-53.0), and 26.71 (95%CI: 8.64-82.57; P < 0.001). Results were reproducible for cases with complete or incomplete criteria separately. NT-proBNP is a reliable marker for the diagnosis of KD. Prospective clinical studies with emphasis on NT-proBNP in a diagnostic algorithm are needed. © 2012 The Authors. Pediatrics International © 2012 Japan Pediatric Society.

    To construct a tool, using computed tomography (CT) imaging and preoperative clinical variables, to estimate successful primary cytoreduction for advanced epithelial ovarian cancer (EOC). Women who underwent primary cytoreductive surgery for stage IIIC/IV EOC at Mayo Clinic between 1/2/2003 and 12/30/2011 and had preoperative CT images of the abdomen and pelvis within 90days prior to their surgery available for review were included. CT images were reviewed for large-volume ascites, diffuse peritoneal thickening (DPT), omental cake, lymphadenopathy (LP), and spleen or liver involvement. Preoperative factors included age, body mass index (BMI), Eastern Cooperative Oncology Group performance status (ECOG PS), American Society of Anesthesiologists (ASA) score, albumin, CA-125, and thrombocytosis. Two prediction models were developed to estimate the probability of (i) complete and (ii) suboptimal cytoreduction (residual disease (RD) >1cm) using multivariable logistic analysis with backward and stepwise variable selection methods. Internal validation was assessed using bootstrap resampling to derive an optimism-corrected estimate of the c-index. 279 patients met inclusion criteria: 143 had complete cytoreduction, 26 had suboptimal cytoreduction (RD>1cm), and 110 had measurable RD ≤1cm. On multivariable analysis, age, absence of ascites, omental cake, and DPT on CT imaging independently predicted complete cytoreduction (c-index=0.748). Conversely, predictors of suboptimal cytoreduction were ECOG PS, DPT, and LP on preoperative CT imaging (c-index=0.685). The generated models serve as preoperative evaluation tools that may improve counseling and selection for primary surgery, but need to be externally validated. Copyright © 2015 Elsevier Inc.

    Falls are common and associated with reduced independence and mortality in Parkinson's disease. Previous research has been conducted on falls-prevalent or advanced disease cohorts. This study identifies risk factors for first fall for 36 months in a newly diagnosed, falls-naïve cohort. A total of 121 consecutive Parkinson's disease patients were recruited. Falls data were collected prospectively during 36 months from diagnosis via monthly falls diaries and telephone follow-up for 117 participants. Assessment comprised a comprehensive battery of clinical, gait, and cognitive measures. Significant predictors were identified from decision-tree analysis and survival analysis with time to first fall during 36 months as the dependent variable. At baseline, 26 (22%) participants reported retrospective falls. At 36 months, the remaining cohort (n = 91) comprised 47 fallers (52%) and 30 (33%) nonfallers and 14 (15%) participants with incomplete diaries. Fallers presented with a significantly higher disease severity, poorer ability to stand on one leg, slower gait speed, increased stance time variability, and higher swing time asymmetry. Median time to first fall was 847 days. Gait speed, stance time, and Hoehn & Yahr III stage emerged as significant predictors of first fall, hazard ratio 3.44 (95% confidence interval [CI] 1.58 to 7.48), 3.31(95% CI 1.40 to 7.80), and 2.80 (95% CI 1.38 to 5.65), respectively. The hazard ratio for risk factors combined was 7.82 (CI 2.80 to 21.84). Interventions that target gait deficit and postural control in early Parkinson's disease may limit the potential for first fall. © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

    It is difficult to differentiate functional heartburn from proton pump inhibitor (PPI) failure. The aims of this study were to assess the role of early wireless esophageal pH monitoring in patients referred with gastroesophageal reflux disease (GERD) and to identify differences in the clinical spectrum among GERD subtypes. We enrolled consecutive referred patients with suspected GERD. After endoscopy on the first visit, all underwent wireless esophageal pH monitoring when off the PPI. Two hundred thirty patients were enrolled. These patients were classified into a reflux esophagitis group (20, 8.7 %) and a normal endoscopic findings group (210, 91.3 %). Among the 210 patients in the normal endoscopic findings group, 63 (27.4 %) were diagnosed with pathological reflux, 35 (15.2 %) with hypersensitive esophagus, 87 (37.8 %) with normal acid exposure with negative symptom association, and 25 (10.9 %) with test failure. These groups did not differ in age, body mass index, smoking habit, alcohol consumption, symptom severity, quality of life, presence of atypical symptoms, overlap with irritable bowel syndrome, and the frequency of somatization, depression, and anxiety. PPI responses were evaluated in 135 patients. Fifty patients (37.0 %) were not responsive to the 4-week treatment; 26 (19.3 %) were diagnosed with refractory non-erosive gastroesophageal disease, and 24 (17.8 %) with functional heartburn. The demographics and clinical and psychological characteristics did not differ between the two groups. Demographic characteristics and symptom patterns alone cannot differentiate functional heartburn from various subtypes of GERD. Wireless esophageal pH monitoring should be considered for the initial evaluation of GERD in the tertiary referral setting.

  11. Metabolic effects of obesity causing disease in childhood.

    Abrams, Pamela; Levitt Katz, Lorraine E

    2011-02-01

    Childhood obesity is rising to epidemic proportions throughout the world, and much emphasis has been placed on the long-term consequences that can result later, in adulthood. This article reviews the metabolic consequences of obesity that can manifest as disease during the childhood years. Obese children suffer from many disease processes once thought to affect only adults. They can have type 2 diabetes mellitus, and potentially early β cell failure with rapid progression to an insulin requirement. There is a high prevalence of fatty liver disease in obese children, and complications such as steatohepatitis and even cirrhosis can develop during childhood. Visceral fat has been shown to have many different properties than subcutaneous fat, and children with central adiposity can develop the metabolic syndrome with insulin resistance, hypertension, and dyslipidemia. Hyperandrogenism, sleep disturbances, and many types of orthopedic complications can also develop in young children. Physicians should not only warn obese children and their families about the long-term consequences of obesity for which they are at risk in adulthood, they should also screen for the many diseases that may already be present.

    Administrative healthcare databases are useful to investigate the epidemiology, health outcomes, quality indicators and healthcare utilisation concerning peptic ulcers and gastrointestinal bleeding, but the databases need to be validated in order to be a reliable source for research. The aim of this protocol is to perform the first systematic review of studies reporting the validation of International Classification of Diseases, 9th Revision and 10th version (ICD-9 and ICD-10) codes for peptic ulcer and upper gastrointestinal bleeding diagnoses. MEDLINE, EMBASE, Web of Science and the Cochrane Library databases will be searched, using appropriate search strategies. We will include validation studies that used administrative data to identify peptic ulcer disease and upper gastrointestinal bleeding diagnoses or studies that evaluated the validity of peptic ulcer and upper gastrointestinal bleeding codes in administrative data. The following inclusion criteria will be used: (a) the presence of a reference standard case definition for the diseases of interest; (b) the presence of at least one test measure (eg, sensitivity, etc) and (c) the use of an administrative database as a source of data. Pairs of reviewers will independently abstract data using standardised forms and will evaluate quality using the checklist of the Standards for Reporting of Diagnostic Accuracy (STARD) criteria. This systematic review protocol has been produced in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol (PRISMA-P) 2015 statement. Ethics approval is not required given that this is a protocol for a systematic review. We will submit results of this study to a peer-reviewed journal for publication. The results will serve as a guide for researchers validating administrative healthcare databases to determine appropriate case definitions for peptic ulcer disease and upper gastrointestinal bleeding, as well as to perform outcome research using

    Heterozygous loss-of-function mutations in the acid beta-glucocerebrosidase (GBA1) gene, responsible for the recessive lysosomal storage disorder, Gaucher's disease (GD), are the strongest known risk factor for Parkinson's disease (PD). Our aim was to assess the contribution of GBA1 mutations in a series of early-onset PD. One hundred and eighty-five PD patients (with an onset age of ≤50) and 283 age-matched controls were screened for GBA1 mutations by Sanger sequencing. We show that the frequency of GBA1 mutations is much higher in this patient series than in typical late-onset patient cohorts. Furthermore, our results reveal that the most prevalent PD-associated GBA1 mutation is E326K, a variant that does not, when homozygous, cause GD. Our results confirm recent reports that the mutation, E326K, predisposes to PD and suggest that, in addition to reduced GBA1 activity, other molecular mechanisms may contribute to the development of the disease.

    Moyamoya disease is a very rare chronic cerebrovascular disease of unknown etiology characterized by recurrent ischemic or hemorrhagic strokes. Initially diagnosed in Japan and named after finding puff of smoke like collateral blood vessels around the occluded blood vessels of circle of Willis. With increase awareness this disease is now diagnosed more often. Medical and surgical treatment have been used to treat the disease, with surgical treatment been mostly experimental. Special attention should be given to the surgical treatment which has shown to have an edge over the medical treatment in some clinical trials especially in young patients with recurrent strokes to prevent progressive cognitive decline and to improve their quality of life. In our patient, who is a young man, the diagnosis was picked up late and when surgical evaluation was performed, it was considered to be fruitless with findings of nonviable brain tissue on MRI imaging.

    Dyskinesia is usually lifelong and progressive; therefore, physicians generally see the disorder in elderly patients. Medical treatment must be carefully selected on the basis of the cause of the dyskinesia. Parkinsonian dyskinesia is well controlled by drug therapy. However, patients can become less responsive to a drug after years of use and may experience unwelcome side effects. Cerebellar tremor is extremely disabling because it worsens with activity, but no satisfactory therapy is available. Senile, essential, and familial tremors are also intensified by action, but they can often be suppressed with a mild tranquilizer or a beta blocker. Drug treatment of blepharospasm and spastic dysphonia has been disappointing: Facial or laryngeal surgery is sometimes required. Tardive dyskinesia is caused by neuroleptic drugs, so the only therapy for the disorder is withdrawal of the offending drug.

    Ribbing disease is a rare form of sclerosing dysplasia characterized by benign endosteal and periosteal bone growth confined to the diaphyses of the long bones, usually the tibiae and femora. It occurs after puberty and is more commonly seen in women. The most common presenting symptom is pain that is usually self-limited; however, progression is known. The etiology and optimal treatment for the disease are as yet undefined. We present here the case of a 31-year-old woman with clinical, radiological and bone scan manifestations of Ribbing disease corroborated by bone biopsy. Radiographs demonstrated cortical thickening of the diaphyses of both tibiae. 99mTc-methylene diphosphonate bone scan revealed intense irregular uptake in diaphyseal region of both tibiae. Magnetic resonance imaging showed cortical thickening with bone marrow edema in bilateral tibial diaphysis with minimal adjacent soft tissue edema. Bone biopsy revealed predominantly dense lamellar bone with irregular sized and spaced haversian systems. Serum and urine markers of bone metabolism were within normal limits. The patient was treated with analgesics, and had partial relief from pain. Medullary rimming is the next treatment option in case pain progresses. This report emphasizes the role of bone scan in the diagnosis of this rare condition

    Inherited kidney disease encompasses a broad range of disorders, with both multiple genes contributing to specific phenotypes and single gene defects having multiple clinical presentations. Advances in sequencing capacity may allow a genetic diagnosis for familial renal disease, by testing the increasing number of known causative genes. However, there has been limited translation of research findings of causative genes into clinical settings. Here, we report the results of a national accredited diagnostic genetic service for familial renal disease. An expert multidisciplinary team developed a targeted exomic sequencing approach with ten curated multigene panels (207 genes) and variant assessment individualized to the patient's phenotype. A genetic diagnosis (pathogenic genetic variant[s]) was identified in 58 of 135 families referred in two years. The genetic diagnosis rate was similar between families with a pediatric versus adult proband (46% vs 40%), although significant differences were found in certain panels such as atypical hemolytic uremic syndrome (88% vs 17%). High diagnostic rates were found for Alport syndrome (22 of 27) and tubular disorders (8 of 10), whereas the monogenic diagnostic rate for congenital anomalies of the kidney and urinary tract was one of 13. Quality reporting was aided by a strong clinical renal and genetic multidisciplinary committee review. Importantly, for a diagnostic service, few variants of uncertain significance were found with this targeted, phenotype-based approach. Thus, use of targeted massively parallel sequencing approaches in inherited kidney disease has a significant capacity to diagnose the underlying genetic disorder across most renal phenotypes.

    We present a case of maternal Grave's disease associated with fetal goitrous hyperthyroidism. Fetal goiter was diagnosed by ultrasound and diagnosis of fetal hyperthyroidism was established by umbilical blood sampling. Fetus was successfully treated by increasing maternal propylthiouracil dosage. Fetal thyroid status was normal at birth. Role of sonography and umbilical blood sampling in management of fetal goiter complicated with maternal Grave's disease is discussed.

    Full Text Available Abstract Background In Great Britain (GB, data collected on pesticide associated illness focuses on acute episodes such as poisonings caused by misuse or abuse. This study aimed to investigate the extent and nature of pesticide-related illness presented and diagnosed in Primary Care and the feasibility of establishing a routine monitoring system. Methods A checklist, completed by General Practitioners (GP for all patients aged 18+ who attended surgery sessions, identified patients to be interviewed in detail on exposures and events that occurred in the week before their symptoms appeared. Results The study covered 59320 patients in 43 practices across GB and 1335 detailed interviews. The annual incidence of illness reported to GPs because of concern about pesticide exposure was estimated to be 0.04%, potentially 88400 consultations annually, approximately 1700 per week. The annual incidence of consultations where symptoms were diagnosed by GPs as likely to be related to pesticide exposure was 0.003%, an annual estimate of 6630 consultations i.e. about 128 per week. 41% of interviewees reported using at least one pesticide at home in the week before symptoms occurred. The risk of having symptoms possibly related to pesticide exposure compared to unlikely was associated with home use of pesticides after adjusting for age, gender and occupational pesticide exposure (OR = 1.88, 95% CI 1.51 – 2.35. Conclusion GP practices were diverse and well distributed throughout GB with similar symptom consulting patterns as in the Primary Care within the UK. Methods used in this study would not be feasible for a routine surveillance system for pesticide related illness. Incorporation of environmental health into Primary Care education and practice is needed.

    Dent disease is an X-linked tubulopathy mainly caused by inactivating mutations of CLCN5. Features of Bartter syndrome such as hypokalemic metabolic alkalosis are rarely observed in patients with Dent disease. We report a Japanese male patient with Dent disease who also manifested features of Bartter syndrome. At the age of 3 years, he was diagnosed with Dent disease based on low molecular weight proteinuria and hypercalciuria. One year later, he was found to have features of Bartter syndrome, i.e., hypokalemia and metabolic alkalosis, and high levels of plasma renin activity and aldosterone with a normal blood pressure. Despite medical interventions, he developed chronic kidney disease stage 3 at the age of 21 years. To investigate the molecular basis of his disease, CLCN5, KCNJ1, SLC12A1, and CLCkb were analyzed and a novel mutation (Y567X) in CLCN5 was identified. Hypokalemic metabolic alkalosis is a rare manifestation in Dent disease. It is speculated that Dent patients with features of Bartter syndrome are susceptible to progression to renal failure. To study this hypothesis, additional observations and long-term follow-up of such patients are necessary.

    Prenatal diagnosis was requested for an undiagnosed eye disease showing X-linked inheritance in a family. No medical records existed for the affected family members. Mapping of the X chromosome and candidate gene mutation screening identified a c.C267A[p.F89L] mutation in NPD previously described as possibly causing Norrie disease. The detection of the c.C267A[p.F89L] variant in another unrelated family confirms the pathogenic nature of the mutation for the Norrie disease phenotype. Gene mapping, haplotype analysis, and candidate gene screening have been previously utilized in research applications but were applied here in a diagnostic setting due to the scarcity of available clinical information. The clinical diagnosis and mutation identification were critical for providing proper genetic counseling and prenatal diagnosis for this family.

    Full Text Available Bacterial diseases in plants are difficult to control. The emphasis is on preventing the spread of the bacteria rather than curing the diseased plant. Integrated management measures for bacterial plant pathogens should be applied for successfull control. Biological control is one of the control measures viz. through the use of microorganisms to suppress the growth and development of bacterial plant pathogen and ultimately reduce the possibility of disease onset. The study of biological control of bacterial plant pathogen was just began compared with of fungal plant pathogen. The ecological nature of diverse bacterial plant pathogens has led scientists to apply different approach in the investigation of its biological control. The complex process of entrance to its host plant for certain soil-borne bacterial plant pathogens need special techniques and combination of more than one biological control agent. Problem and progress in controlling bacterial plant pathogens biologically will be discussed in more detail in the paper and some commercial products of biological control agents (biopesticides will be introduced.     Penyakit tumbuhan karena bakteri sulit dikendalikan.

    2014-01-01

    Background Knowledge regarding the health-related quality of life (HRQoL) of children with celiac disease remains limited and inconclusive. We investigated the HRQoL of three groups of 12-year-olds with: i) undetected celiac disease ii) clinically diagnosed celiac disease, and iii) without celiac disease. Methods A school-based cross-sectional multicenter screening study invited 18 325 children, whereof 68% consented to participate. Participants provided a blood sample, which was later analyzed for anti-tissue-tranglutaminase antibodies, and alongside filled in a questionnaire. When anti-tissue-tranglutaminase antibodies were elevated, a small intestinal biopsy verified the screening-detected celiac disease diagnosis. Self-reported HRQoL was measured using Kidscreen, a generic 52 items instrument with proven reliability and validity. Scores were linearly transformed into a 0–100 scale with higher values indicating better HRQoL. Mean values with standard deviations (mean ± SD) were compared, and uni- and multivariate logistic regression models tested the odds of a low HRQoL among children with undetected or diagnosed celiac disease, respectively. Results Children with undetected celiac disease (n = 238) reported similar HRQoL as children without celiac disease (n = 12 037) (83.0 ± 11.0 vs. 82.5 ± 11.3, P = 0.51), and also similar HRQoL (82.2 ± 12.2, P = 0.28) to that of children with diagnosed celiac disease (n = 90), of whom 92% were adherent to treatment. Having undetected celiac disease did not increase the odds of low overall HRQoL, independent of sex, area of residence, study year and occurrence of gastrointestinal symptoms (adjusted odds ratio 0.77, 95% CI 0.54-1.10). Comparable results were seen for diagnosed celiac disease cases (adjusted odds ratio 1.11, 95% CI 0.67-1.85). Conclusion Children with undetected celiac disease reported comparable HRQoL as their peers with diagnosed celiac disease, and those without celiac disease

    Genetic factors influencing lung function may predispose to chronic obstructive pulmonary disease (COPD). The fibroblast growth factor 10 (FGF10) signalling pathway is critical for lung development and lung epithelial renewal. The hypothesis behind this study was that constitutive FGF10 insufficiency may lead to pulmonary disorder. Therefore investigation of the pulmonary functions of patients heterozygous for loss of function mutations in the FGF10 gene was performed. The spirometric measures of lung function from patients and non-carrier siblings were compared and both groups were related to matched reference data for normal human lung function. The patients show a significant decrease in lung function parameters when compared to control values. The average FEV1/IVC quota (FEV1%) for the patients is 0.65 (80% of predicted) and reversibility test using Terbutalin resulted in a 3.7% increase in FEV1. Patients with FGF10 haploinsufficiency have lung function parameters indicating COPD. A modest response to Terbutalin confirms an irreversible obstructive lung disease. These findings support the idea that genetic variants affecting the FGF10 signalling pathway are important determinants of lung function that may ultimately contribute to COPD. Specifically, the results show that FGF10 haploinsufficiency affects lung function measures providing a model for a dosage sensitive effect of FGF10 in the development of COPD.

    The aim of this review is to evaluate the role of inflammatory spine disease in patients with chronic back pain. The contribution of imaging modalities for the diagnostic evaluation of back pain is discussed. A systematic literature search based on the classification of seronegative spondyloarthropathies and rheumatoid arthritis was performed. The results of this search and the experiences in a large collective of rheumatological patients are analyzed. The prevalence of rheumatoid arthritis (1-2%) is comparable to that of spondyloarthropathies (1.9%). The etiology of these entities is not fully elucidated. Magnetic resonance imaging is increasingly used for early detection and surveillance of therapy with TNF-α antagonists. Bone marrow edema, which is only detectable with MRI, represents an early sign of inflammation. Therapy with TNF-α antagonists is based on clinical and laboratory criteria, and signs of inflammation in MRI. MRI is useful for assessment of the effectiveness of anti-inflammatory therapy. (orig.)

    Many important clues have been provided by the relationship of certain medications to lupus and other autoimmune syndromes. These are temporary conditions that resolve when the medication is removed. There are now over 70 such medications which have been reported related to these autoimmune conditions. Interest continues to grow in the potential for environmental substances to cause these syndromes. Among those under suspicion are hydrazines, tartrazines, hair dyes, trichloroethylene, industrial emissions and hazardous wastes. Other possible associations include silica, mercury, cadmium, gold and L canavanine. Two recognised outbreaks include 'toxic oil syndrome' related to contaminated rape seed oil in Spain in 1981 and exposure to a contaminated environmental substance associated with an autoimmune attack on muscle tissue in 1989. Recently, there have been proposals made for the definition and identification of environmentally associated immune disorders. The World Health Organisation (WHO) has also provided recent publications for other environmentally related problems. All these aspects will be presented and reviewed in detail

    Since the control rate of blood pressure is lower in mainland China, the aim of this study is to investigate the proportion of secondary causes and coexisting diseases of hypertension in hypertensive patients. Data on consecutive patients with hypertension who visited the Hypertension Center. Diseases were detected using an established strict screening protocol. Detection rate of secondary causes and coexisting diseases of hypertension was 39.5% among 3003 hypertensive patients. Obstructive sleep apnea (OSA) was the most common, accounting for 24.7% of patients, followed by primary aldosteronism (PA) (5.8%) and PA + OSA (4.9%). Endocrine hypertension accounted for 12.1% of patients, including 10.7% of patients with PA, 1.1% with hypothyroidism, 0.1% with pheochromocytoma, 0.1% with Cushing's syndrome, and 0.1% with hyperthyroidism, respectively. Those who smoke, those who are obese, and those who have diabetes accounted for 31.3%, 27.5%, and 16.6% of total patients, respectively. There were overlapping conditions in secondary causes and coexisting diseases of hypertension. OSA was the most common in each age- and BMI-stratified group. Findings from the current study suggest an increasing frequency of secondary forms of hypertension, highlighting the burden of OSA and PA in hypertensive patients.

    Background: Recent data suggest that neuroendocrine signaling pathways may play a role in the progression of prostate cancer, particularly for early-stage disease. We aimed to explore whether expression of selected genes in the adrenergic, serotoninergic, glucocorticoid, and dopaminergic pathways differs in prostate tumor tissue from men with lethal disease compared with men with nonlethal disease. Methods: On the basis of the Swedish Watchful Waiting Cohort, we included 511 men diagnosed with incidental prostate cancer through transurethral resection of the prostate during 1977-1998 with follow-up up to 30 years. For those with tumor tissue ( N = 262), we measured mRNA expression of 223 selected genes included in neuroendocrine pathways. Using DNA from normal prostate tissue ( N = 396), we genotyped 36 SNPs from 14 receptor genes. Lethal prostate cancer was the primary outcome in analyses with pathway gene expression and genetic variants. Results: Differential expression of genes in the serotoninergic pathway was associated with risk of lethal prostate cancer ( P = 0.007); similar but weaker associations were noted for the adrenergic ( P = 0.014) and glucocorticoid ( P = 0.020) pathways. Variants of the HTR2A (rs2296972; P = 0.002) and NR3CI (rs33388; P = 0.035) genes (within the serotoninergic and glucocorticoid pathways) were associated with lethal cancer in overdominant models. These genetic variants were correlated with expression of several genes in corresponding pathways ( P pathways, particularly serotoninergic pathway, are associated with lethal outcome in the natural course of localized prostate cancer. Impact: This study provides evidence of the role of neuroendocrine pathways in prostate cancer progression that may have clinical utility.

    A total of 26,203 of the deaths in Jerez de los Caballeros (Badajoz) during the 19th century were collected and grouped according to the Bertillon's Classification, in order to study the causes of death from rheumatic diseases. An analysis was made using the Death Registers, those located in the Parish Archives, and files of the Municipal Archives. There were a total of 31 deaths due to rheumatic diseases, with the 65-74 years age group being most frequent. The lack of records may be due to the inaccuracy of the diagnoses. September was the month of increased mortality. Copyright © 2014 Elsevier España, S.L.U. y Sociedad Española de Reumatología y Colegio Mexicano de Reumatología. All rights reserved.

    Gastroesophageal reflux disease (GERD) is a gastrointestinal disorder in which stomach acids are chronically regurgitated into the esophagus and oral cavity. Continual exposure of the teeth to these acids can cause severe tooth wear. Dentists are often the first healthcare professionals to diagnose dental erosion in patients with GERD. This article presents a case report of a 27-year-old male smoker with tooth wear and dentin sensitivity caused by GERD associated with bruxism. After diagnosis, a multidisciplinary treatment plan was established. The initial treatment approach consisted of medical follow-up with counseling on dietary and smoking habits, as well as management of the gastric disorders with medication. GERD management and the dental treatment performed for the eroded dentition are described, including diagnosis, treatment planning, and restorative therapy.

    Psychological disorders have been associated with irritable bowel syndrome (IBS) for decades in the absence of other objective etiology. However, such associations are also evident in other chronic diseases with more clearly defined pathogenesis such as ulcerative colitis. In this study, we examined the prevalence and severity of psychological disorders among IBS and ulcerative colitis (UC) patients relative to healthy controls. A review was conducted of English-language literature to identify case-control studies reporting the prevalence of depression or anxiety in IBS and UC populations relative to healthy controls. Our primary endpoint was the pooled prevalence or average score of depression or anxiety in an IBS or UC population relative to healthy control. Seven case-control studies evaluating IBS and three evaluating UC were included. All IBS and UC studies reported excess prevalence and severity of depression as well as anxiety, relative to healthy controls. The prevalence of depression in excess of healthy controls was 39% in UC case-control trials and 33% in IBS studies, and excess anxiety was present in UC (42%) and IBS (19%) case-control trials as well. Anxiety and depression scores were higher (representing more severe symptoms) in both UC and IBS patients compared to healthy controls. Anxiety and depressive disorders are associated with both IBS and UC. The non-specific association between these psychological and gastrointestinal disorders could suggest that chronic gastrointestinal illness might affect psychosocial behavior.

    To explore the pathogenesis of ano-rectal diseases caused by deficiency of Qi, which is correlated with obstruction of pulmonary ventilation. The pulmonary ventilatory function was measured in 100 patients with the internal piles, the interno-external hemorrhoid and prolapse of rectum, the prolapse of anus was the principal symptom of them. Data from the 100 patients showed that 67% of them were diagnosed with the obstruction of pulmonary ventilation, the ratio was far less in the health control group. FEV 1.0 (mean +/- s) (2011.65 +/- 875) ml, MMF (1.84 +/- 1.24) L/s and PEF (2.34 +/- 1.51) L/s in male patients, (1551.54 +/- 514) ml, (1.57 +/- 0.62) L/s and (1.85 +/- 0.92) L/s in female patients, but those values were higher in the control than in the patients. The statistical analysis was performed and the difference was significant between patients and the control group (P < 0.01). The patients with ano-rectal diseases caused by deficiency of Qi accompanied with obstruction of pulmonary ventilation in different degree and varied sorts, it confirmed that the pathogenesis of ano-rectal diseases caused by deficiency of Qi is related with "sinking of pectoral Qi".

    The uveitis masquerade syndromes (UMS) are a group of ocular diseases that may mimic chronic intraocular inflammation. Many malignant entities such as non-Hodgkin's lymphomas may masquerade as uveitis. We report a case of an HIV-positive patient with masquerade syndrome presenting unilateral uveitis. 45-year-old Caucasian man with a diagnosis of diffuse large B-cell lymphoma (DLBCL). The patient was diagnosed by a biopsy of an abdominal mass which showed fragments of gastric mucosa with diffuse growth of neoplastic cells. At diagnosis, the patient suffered from unilateral blurring of vision and a sudden decrease of left-eye visual acuity. A slit-lamp examination of the left eye revealed a diagnosis of anterior uveitis. The patient exhibited no signs of posterior uveitis. An anterior-chamber paracentesis was performed and analyzed by multiparameter flow cytometry (MFC), showing cells CD45, CD19, CD20, CD22, and CD38 positives, and moderate expression of CD10 with kappa light chain restriction, showing a monoclonal B-cell population. The patient received CHOP-R with intrathecal methotrexate followed by consolidation high dose methotrexate obtaining a complete response which is ongoing. Differential diagnosis between chronic uveitis and ocular lymphoma may be challenging. We advocate anterior-chamber paracentesis in cases of refractory uveitis in patients with hematologic malignancies. © 2016 International Clinical Cytometry Society. © 2016 International Clinical Cytometry Society.

    Full Text Available Spinal pain is of great socioeconomic significance as it is widely prevalent and a common cause of disability. However, the diagnosis of its true causes frequently leads to problems. A study has been conducted to evaluate the accuracy of a clinical diagnosis and its coding in conformity with the International Classification of Diseases. The diagnosis of vertebral osteochondrosis and the hypodiagnosis of nonspecific and nonvertebrogenic pain syndromes have been found to be unreasonably widely used. Ways to solve these problems have been proposed, by applying approaches to diagnosing the causes of spinal pain in accordance with international practice.

    To identify the protozoa responsible for intestinal parasitosis diagnosed at Le Dantec University Hospital in Dakar, Senegal. The retrospective study included 2578 patients for whom stool samples were analyzed from 2011 to 2015. The sex ratio was 1.1. Patients' mean age was 28.5 years, with a range of 11 days to 91 years. Direct examination and the Ritchie technique were performed to search for parasites. In total, 317 patients had intestinal protozoa, for a prevalence of 12.3 %. Infections involved one (91%) or two parasites (9%). The most common species found alone were Entamoeba coli (51.5%), E. histolytica/E. dispar (17 %), and Giardia intestinalis (10.5%). The most common associations were E. coli with G. intestinalis (3.6 %) and with E. histolytica (2.4%). These infections affected significantly more outpatients than inpatients (65 %, p = 0.0049) and slightly more women (51.1%, p = 0.22) than men. Adults accounted for 67% of the confirmed intestinal protozoa: 39% aged 31-60 years, 28% aged 15-30, and only 7% older than 60 (p = 0.5). Most of the protozoa isolated were non-pathogenic. However, health education should be promoted in addition to the mass treatment program already begun to limit and even halt the spread of these neglected diseases.

  13. The added value of using mutational profiling in addition to cytology in diagnosing aggressive pancreaticobiliary disease: review of clinical cases at a single center

    2014-01-01

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

    Full Text Available Abstract Background More people will probably continue working into old age in the future due to the increased size of aging populations in many countries. We therefore need to know more about older workers’ health in relation to their work situation and retirement. This study is a part of a theoretical development of older workers’ situations. Older workers’ situations are theoretically themed in nine areas by the authors of this study. The aims of the study were to investigate the relationship between: i diagnosed disease and factors in older workers’ situations, theoretically themed in nine areas; ii self-rated health and factors in older workers’ situations, theoretically themed in nine areas; iii diagnosed disease and self-rated health; and iv the relationships between these health measures and retirement. Methods A questionnaire-based cross-sectional study, using logistic regression, with 1,756 health care personnel aged 55–64 years. The questionnaire used gave an overview of most different areas in the older workers’ situations. Result There was a difference in the participants’ frequency of objectively specified diagnosed disease and their subjectively experienced self-rated health. A bad self-rated health was related higher to early retirement than diagnosed diseases. In the multivariate model, having ‘Diagnosed disease’ was not significantly related to whether older workers thought they could not work beyond 65 years of age. A bad ‘Self-rated health’ was also more highly related to whether older workers thought they could not work beyond 65 years, than if the respondents stated that a ‘Diagnosed disease is a hindrance in my daily work’ in the multivariate model. Conclusion This study showed an important difference between older workers’ own experiences and the effect of their self-rated health and their diagnosed diseases. Subjective self-rated health seems to be more important to people’s retirement

  15. Heart and skeletal muscle inflammation (HSMI disease diagnosed on a British Columbia salmon farm through a longitudinal farm study.

    Emiliano Di Cicco

    Full Text Available Heart and skeletal muscle inflammation (HSMI is an emerging disease of marine-farmed Atlantic Salmon (Salmo salar, first recognized in 1999 in Norway, and later also reported in Scotland and Chile. We undertook a longitudinal study involving health evaluation over an entire marine production cycle on one salmon farm in British Columbia (Canada. In previous production cycles at this farm site and others in the vicinity, cardiac lesions not linked to a specific infectious agent or disease were identified. Histologic assessments of both live and moribund fish samples collected at the farm during the longitudinal study documented at the population level the development, peak, and recovery phases of HSMI. The fish underwent histopathological evaluation of all tissues, Twort's Gram staining, immunohistochemistry, and molecular quantification in heart tissue of 44 agents known or suspected to cause disease in salmon. Our analysis showed evidence of HSMI histopathological lesions over an 11-month timespan, with the prevalence of lesions peaking at 80-100% in sampled fish, despite mild clinical signs with no associated elevation in mortalities reported at the farm level. Diffuse mononuclear inflammation and myodegeneration, consistent with HSMI, was the predominant histologic observation in affected heart and skeletal muscle. Infective agent monitoring identified three agents at high prevalence in salmon heart tissue, including Piscine orthoreovirus (PRV, and parasites Paranucleospora theridion and Kudoa thyrsites. However, PRV alone was statistically correlated with the occurrence and severity of histopathological lesions in the heart. Immunohistochemical staining further localized PRV throughout HSMI development, with the virus found mainly within red blood cells in early cases, moving into the cardiomyocytes within or, more often, on the periphery of the inflammatory reaction during the peak disease, and reducing to low or undetectable levels later in

    Full Text Available Sin Hang Lee,1,21Pathology Department, Milford Hospital, Milford, CT, USA; 2Milford Molecular Diagnostics, Milford, CT, USA Abstract: Lyme disease (LD, the most common tick-borne disease in North America, is believed to be caused exclusively by Borrelia burgdorferi sensu stricto and is usually diagnosed by clinical evaluation and serologic assays. As reported previously in a peer-reviewed article, a 13-year-old boy living in the Northeast of the USA was initially diagnosed with LD based on evaluation of his clinical presentations and on serologic test results. The patient was treated with a course of oral doxycycline for 28 days, and the symptoms resolved. A year later, the boy developed a series of unusual symptoms and did not attend school for 1 year. A LD specialist reviewed the case and found the serologic test band patterns nondiagnostic of LD. The boy was admitted to a psychiatric hospital. After discharge from the psychiatric hospital, a polymerase chain reaction test performed in a winter month when the boy was 16 years old showed a low density of B. burgdorferi sensu lato in the blood of the patient, confirmed by partial 16S rRNA (ribosomal RNA gene sequencing. Subsequent DNA sequencing analysis presented in this report demonstrated that the spirochete isolate was a novel strain of B. burgdorferi with two homeologous 16S rRNA genes, which has never been reported in the world literature. This case report shows that direct DNA sequencing is a valuable tool for reliable molecular diagnosis of Lyme and related borrelioses, as well as for studies of the diversity of the causative agents of LD because LD patients infected by a rare or novel borrelial variant may produce an antibody pattern that can be different from the pattern characteristic of an infection caused by a typical B. burgdorferi sensu stricto strain. Keywords: Lyme disease, Borrelia burgdorferi, homeologous 16S rRNA genes, DNA sequencing

  18. Prediction of disease causing non-synonymous SNPs by the Artificial Neural Network Predictor NetDiseaseSNP.

    Directory of Open Access Journals (Sweden)

    Morten Bo Johansen

    Full Text Available We have developed a sequence conservation-based artificial neural network predictor called NetDiseaseSNP which classifies nsSNPs as disease-causing or neutral. Our method uses the excellent alignment generation algorithm of SIFT to identify related sequences and a combination of 31 features assessing sequence conservation and the predicted surface accessibility to produce a single score which can be used to rank nsSNPs based on their potential to cause disease. NetDiseaseSNP classifies successfully disease-causing and neutral mutations. In addition, we show that NetDiseaseSNP discriminates cancer driver and passenger mutations satisfactorily. Our method outperforms other state-of-the-art methods on several disease/neutral datasets as well as on cancer driver/passenger mutation datasets and can thus be used to pinpoint and prioritize plausible disease candidates among nsSNPs for further investigation. NetDiseaseSNP is publicly available as an online tool as well as a web service: http://www.cbs.dtu.dk/services/NetDiseaseSNP.

    Directory of Open Access Journals (Sweden)

    Andrei Vasile OLTEANU

    2015-12-01

    Full Text Available Background: Numerous studies worldwide have assessed the association between dental erosions or other related oral manifestations, and the gastroesophageal reflux disease (GERD. Nowadays, one of the main therapeutic resources of GERD is represented by proton pump inhibitors (PPIs. Adequate salivary secretions and flow are considered mandatory for the protection of both teeth and esophageal mucosa. The aim of the present study was to evaluate the possible correlation between GERD treatment options and subsequent control of oral manifestation, taking as premises that either PPIs or dietary and lifestyle changes may control oral patterns of GERD by acting on salivary secretions. Methods: 48 clinically diagnosed GERD adult patients with oral manifestations, mainly erosions, were included in the study, none of which showing alarming symptoms that would require further gastroenterologic examination. Oral examination evaluated the DMF (decayed, missing, filled and OHI-S (Simplified Oral Hygiene indices. Salivary flow was evaluated by the Saxon test. 25 patients were prescribed dietary and lifestyle measures and PPIs (omeprazole – 20 mg, whereas 23 patients were managed only through dietary and lifestyle modifications. General assessment was performed at the time of diagnosis and 4 weeks afterwards. Results: No significant differences as to the DMF index, OHI-S index or Saxon test were found over the 4 weeks management between the groups. Conclusions: Oral manifestation of GERD may be caused by impaired salivary secretions and flow, otherwise no - positive or negative - effect could be secondary to PPI therapy. Accordingly, complex oral rehabilitation of GERD patients and collaboration between gastroenterologists and dentists should be promoted.

    The study examined the relationship between functional limitation due to chronic diseases and absenteeism among full-time workers. The studied chronic diseases include arthritis/rheumatism, cancer, diabetes, heart disease, hypertension, lung disease, and stroke. We analyzed data from the 2011 to 2013 National Health Interview Survey. Economic impact was determined by workdays lost and lost income. Increase in absenteeism was observed for each studied condition. Employees with multiple conditions also saw increase absenteeism. Employers lose 28.2 million workdays annually ($4.95 billion in lost income) due to functional limitation caused by chronic diseases. The results show a burden on society due to functional limitation caused by studied chronic diseases. Employers should look into implementing intervention/prevention programs, such as the Chronic Disease Self-Management Programs, to help reduce the cost associated with absenteeism.

    As the prevalence and clinical characteristics of non-alcoholic fatty liver disease (NAFLD) are still unknown in ketosis-onset diabetes, the present study compared the characteristics of NAFLD in type 1 diabetes (T1D), ketosis-onset and non-ketotic type 2 diabetes (T2D) patients. This cross-sectional study was performed with newly diagnosed Chinese patients with diabetes, including 39 T1D, 165 ketosis-onset and 173 non-ketotic T2D, with 30 non-diabetics included as controls. NAFLD was determined by hepatic ultrasonography, then its clinical features were analyzed and its associated risk factors evaluated. NAFLD prevalence in patients with ketosis-onset diabetes (61.8%) was significantly higher than in controls (23.3%; P=0.003) and in T1D patients (15.4%; Pketosis-onset and non-ketotic T2D patients (52.6%; P=0.229), although BMI and alanine aminotransferase (ALT) proved to be independent risk factors for the presence of NAFLD in both these groups whereas, in T1D patients, serum uric acid levels were independent risk factors. NAFLD prevalence and risk factors in ketosis-onset diabetes were similar to those in non-ketotic T2D, but different from those in T1D. These data provide further evidence that ketosis-onset diabetes should be classified as a subtype of T2D rather than idiopathic T1D. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

    Full Text Available To describe and compare temporal changes in prevalence and incidence of psychotropic use (antipsychotics, antidepressants and benzodiazepines and related drugs; BZDRs in persons with newly diagnosed Alzheimer's disease (AD between university hospital districts of Finland during 2005-2011.The MEDALZ study includes all community-dwellers of Finland who received a clinically verified AD diagnosis in 2005-2011 (N = 70,718. Prevalent and incident use of psychotropics among those who had received AD diagnosis less than one year ago were compared in 2005-2011.Regional differences in psychotropic use between university hospital districts were more evident in 2005 than 2011 for prevalent use of any psychotropic, antipsychotic and BZDRs and incident use of any psychotropic and antipsychotics. Regional differences in prevalent antidepressant use and incident BZDR use remained similar during the follow-up, while differences in incident antidepressant use increased during the follow-up. The prevalence of any psychotropic use in 2005 varied between 44.7-50.7% and between 45.0-47.9% in 2011. Incidence of any psychotropic use in 2005 was between 8.6-12.1% and 6.2-8.2% in 2011. In 2005, the distribution of incident psychotropic use followed a large scale spatial variation that, however, did not correspond to university hospital districts. During the study period from 2005 to 2011 the cyclic spatial variation disappeared. No sign of adjacent hospital districts being more or less closely related to each other compared to hospital districts in general was detected.Except for antidepressants, regional differences in psychotropic use have mainly diminished between 2005 and 2011. Our findings highlight the importance of acknowledging regional differences in a country with relatively homogeneous healthcare system and conducting future studies assessing the reasons behind these differences.

    Alzheimer's disease is a leading cause of morbidity and mortality among the elderly. Several families have been described in which Alzheimer's disease is caused by an autosomal dominant gene defect. The chromosomal location of this defective gene has been discovered by using genetic linkage to DNA markers on chromosome 21. The localization on chromosome 21 provides an explanation for the occurrence of Alzheimer's disease-like pathology in Down syndrome. Isolation and characterization of the gene at this locus may yield new insights into the nature of the defect causing familial Alzheimer's disease and possibly, into the etiology of all forms of Alzheimer's disease.

  10. Pathology, toxicology, and latency of irritant gases known to cause bronchiolitis obliterans disease: Does diacetyl fit the pattern?

    Directory of Open Access Journals (Sweden)

    Brent D. Kerger

    2015-01-01

    Full Text Available Bronchiolitis obliterans (BO is a rare disease involving concentric bronchiolar fibrosis that develops rapidly following inhalation of certain irritant gases at sufficiently high acute doses. While there are many potential causes of bronchiolar lesions involved in a variety of chronic lung diseases, failure to clearly define the clinical features and pathological characteristics can lead to ambiguous diagnoses. Irritant gases known to cause BO follow a similar pathologic process and time course of disease onset in humans. Studies of inhaled irritant gases known to cause BO (e.g., chlorine, hydrochloric acid, ammonia, nitrogen oxides, sulfur oxides, sulfur or nitrogen mustards, and phosgene indicate that the time course between causal chemical exposures and development of clinically significant BO disease is typically limited to a few months. The mechanism of toxic action exerted by these irritant gases generally involves widespread and severe injury of the epithelial lining of the bronchioles that leads to acute respiratory symptoms which can include lung edema within days. Repeated exposures to inhaled irritant gases at concentrations insufficient to cause marked respiratory distress or edema may lead to adaptive responses that can reduce or prevent severe bronchiolar fibrotic changes. Risk of BO from irritant gases is driven substantially by toxicokinetics affecting concentrations occurring at the bronchiolar epithelium. Highly soluble irritant gases that cause BO like ammonia generally follow a threshold-dependent cytotoxic mechanism of action that at sufficiently high doses results in severe inflammation of the upper respiratory tract and the bronchiolar epithelium concurrently. This is followed by acute respiratory distress, pulmonary edema, and post inflammatory concentric fibrosis that become clinically obvious within a few months. In contrast, irritant gases with lower solubility like phosgene also follow a threshold-dependent mechanism

    To detect the disease-causing genes of 10 retinitis pigmentosa pedigrees by using exon combined target region capture sequencing chip. Pedigree investigation study. From October 2010 to December 2013, 10 RP pedigrees were recruited for this study in Ningxia Eye Hospital. All the patients and family members received complete ophthalmic examinations. DNA was abstracted from patients, family members and controls. Using exon combined target region capture sequencing chip to screen the candidate disease-causing mutations. Polymerase chain reaction (PCR) and direct sequencing were used to confirm the disease-causing mutations. Seventy patients and 23 normal family members were recruited from 10 pedigrees. Among 10 RP pedigrees, 1 was autosomal dominant pedigrees and 9 were autosomal recessive pedigrees. 7 mutations related to 5 genes of 5 pedigrees were detected. A frameshift mutation on BBS7 gene was detected in No.2 pedigree, the patients of this pedigree combined with central obesity, polydactyly and mental handicap. No.2 pedigree was diagnosed as Bardet-Biedl syndrome finally. A missense mutation was detected in No.7 and No.10 pedigrees respectively. Because the patients suffered deafness meanwhile, the final diagnosis was Usher syndrome. A missense mutation on C3 gene related to age-related macular degeneration was also detected in No. 7 pedigrees. A nonsense mutation and a missense mutation on CRB1 gene were detected in No. 1 pedigree and a splicesite mutation on PROM1 gene was detected in No. 5 pedigree. Retinitis pigmentosa is a kind of genetic eye disease with diversity clinical phenotypes. Rapid and effective genetic diagnosis technology combined with clinical characteristics analysis is helpful to improve the level of clinical diagnosis of RP.

    The evidence that stress may provoke Graves' hyperthyroidism in genetically susceptible subjects is substantial. Whether exposure to stress is related to the severity of thyrotoxicosis has not been studied. Advancing age is associated with not only less severe Graves' hyperthyroidism but also self-reported stress. We tested the hypothesis whether advancing age is associated with less exposure to stress, resulting in a lower immunological response, and less severe Graves' hyperthyroidism. Cross-sectional multicenter study. Two hundred and sixty-three consecutive untreated patients with a first episode of Graves' hyperthyroidism were included. The severity of Graves' hyperthyroidism was evaluated biochemically (freeT(4)-index and freeT(3)-index, thyrotropin-binding inhibitory immunoglobulin (TBII)) and clinically by the hyperthyroid symptom scale score (HSS score). Stress exposure was quantitated by three questionnaires. Advancing age was associated with less severe Graves' hyperthyroidism, both biochemically by lower serum freeT(3)-index and freeT(4)-index (Phyperthyroidism. Advancing age was associated with lower scores for stress exposure. Multivariate regression analysis showed that HSS score was independently related to the tendency to report negative feelings (Phyperthyroidism. Because no direct relationship exists between stress exposure and TBII or freeT(3)-index and freeT(4)-index, we reject our hypothesis that less stress is causally related to biochemically less severe Graves' hyperthyroidism in old age. HSS score is primarily determined by negative feelings and not by age.

    Diseases to the cow's hoof, interdigital skin and legs are highly prevalent and of large economic impact in modern dairy farming. In order to support farmer's decisions on preventing and treating lameness and its underlying causes, decision support models can be used to predict the economic profitability of such actions. An existing approach of modelling lameness as one health disorder in a dynamic, stochastic and mechanistic simulation model has been improved in two ways. First of all, three underlying diseases causing lameness were modelled: digital dermatitis, interdigital hyperplasia and claw horn diseases. Secondly, the existing simulation model was set-up in way that it uses hyper-distributions describing diseases risk of the three lameness causing diseases. By combining information on herd level risk factors with prevalence of lameness or prevalence of underlying diseases among cows, marginal posterior probability distributions for disease prevalence in the specific herd are created in a Bayesian network. Random draws from these distributions are used by the simulation model to describe disease risk. Hereby field data on prevalence is used systematically and uncertainty around herd specific risk is represented. Besides the fact that estimated profitability of halving disease risk depended on the hyper-distributions used, the estimates differed for herds with different levels of diseases risk and reproductive efficiency.

    Mitochondrial diseases display pathological phenotypes according to the mixture of mutant versus wild-type mitochondrial DNA (mtDNA), known as heteroplasmy. We herein examined the impact of nuclear reprogramming and clonal isolation of induced pluripotent stem cells (iPSC) on mitochondrial heteroplasmy. Patient-derived dermal fibroblasts with a prototypical mitochondrial deficiency diagnosed as mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) demonstrated mitochondrial dysfunction with reduced oxidative reserve due to heteroplasmy at position G13513A in the ND5 subunit of complex I. Bioengineered iPSC clones acquired pluripotency with multilineage differentiation capacity and demonstrated reduction in mitochondrial density and oxygen consumption distinguishing them from the somatic source. Consistent with the cellular mosaicism of the original patient-derived fibroblasts, the MELAS-iPSC clones contained a similar range of mtDNA heteroplasmy of the disease-causing mutation with identical profiles in the remaining mtDNA. High-heteroplasmy iPSC clones were used to demonstrate that extended stem cell passaging was sufficient to purge mutant mtDNA, resulting in isogenic iPSC subclones with various degrees of disease-causing genotypes. On comparative differentiation of iPSC clones, improved cardiogenic yield was associated with iPSC clones containing lower heteroplasmy compared with isogenic clones with high heteroplasmy. Thus, mtDNA heteroplasmic segregation within patient-derived stem cell lines enables direct comparison of genotype/phenotype relationships in progenitor cells and lineage-restricted progeny, and indicates that cell fate decisions are regulated as a function of mtDNA mutation load. The novel nuclear reprogramming-based model system introduces a disease-in-a-dish tool to examine the impact of mutant genotypes for MELAS patients in bioengineered tissues and a cellular probe for molecular features of individual

    Diseases of the liver and biliary system are common causes of acute abdominal pain and gallstone disease predisposes to cholecystitis and cholangiolithiasis. Sonography is the method of choice for the assessment of cholecystitis, whereas magnetic resonance cholangiopancreaticography (MRCP) is the standard technique to detect stones in the common bile duct. Multi-detector computed tomography (MDCT) is ideal for detection of associated complications, including abscess formation and gall stone ileus. Pyogenic, amebic and fungal liver abscesses are reliably diagnosed with MDCT which can also be used for interventional radiologic therapy of liver abscesses by percutaneous aspiration or drainage procedures. The second most common cause of liver rupture after blunt trauma is spontaneous rupture of hypervascular liver tumors (i.e., HCC, adenoma, angiosarcoma) and due to medical procedures. Multi-phase contrast-enhanced MDCT can reliably detect active bleeding to guide further therapy in these cases. (orig.)

    Hematemesis in a healthy newborn is most often caused by swallowed maternal blood. Maternal blood due to fibrocystic breast disease in human milk has not previously been reported in the literature. We report here a newborn case with hematemesis in which the mother had fibrocystic breast disease, and we want to emphasize this rare entity. Physicians should be aware of this rare condition, and fibrocystic breast disease of the mother should be included in the differential diagnosis of newborns with hematemesis.

    Immunoglobulin G4-related sclerosing disease (IgG4-RSD) represents a recently identified inflammatory disorder in which infiltration of IgG4 plasma cells causes fibrosis in organs. While IgG4-RSD is well documented in the pancreas and other organs, it is poorly characterized in the thyroid gland. We report a case of a 48-year-old female with a fibrotic thyroid mass associated with a retroperitoneal fibrosis. Diagnosed early as Riedel disease, the high serum IgG4, immunohistopathology and decreased fibrosis with corticosteroid therapy, finally confirm for the first time, the origin of IgG4-RSD fibrosis of the thyroid.

    Full Text Available ABSTRACT CONTEXT: Rapunzel syndrome is a rare form of gastric trichobezoar that develops through outstretching of the bezoar from the stomach to the intestine. CASE REPORT: A 12-year-old girl who had been diagnosed with celiac disease six years earlier was brought to the department of pediatric gastroenterology because of abdominal distension. A palpable mass was detected. A trichobezoar that stretched to the small intestine was removed surgically. The patient was diagnosed as having anxiety and depressive disorder, and treatment started. Following the treatment, her previous trichophagia completely disappeared. CONCLUSION: Presence of trichobezoar should be kept in mind, especially when young girls who have psychiatric problems suffer from gastrointestinal symptoms.

    Irreversible sequels of some genetic diseases can be prevented by neonatal screening. The aim of this paper was to verify the prevalence of diseases diagnosed by the National Program of Neonatal Screening (PNTN) in Maringá, Paraná, Brazil, between 2001 and 2006. This cross-sectional descriptive study included 20,529 newborn infants screened by that program. Out of those, 859 were re-examined, and 21 had the disease confirmed. Considering all screened newborn infants and the number of diagnostics per disease, the following disease prevalence was determine: phenylketonuria--1:20,529; congenital hypothyrodism--1:2,281; hemoglobinopahies--1:3,421; cystic fibrosis--1:10,264; and biotinidase deficiency--1:6,843. Understanding disease status and prevalence of newborns in a population allows the establishment and the improvement of public policies aimed at the children.

    Undiagnosed and untreated celiac disease (CD) constitutes an increasing skeletal health problem due to its association with low bone density and fractures. Examinations of skeletal status in children using dual-energy X-ray absorptiometry (DXA) are prone to size-related misinterpretation. In contrary, the analysis of muscle-bone relationship seems to limit a possibility of misdiagnosis because skeletal status is evaluated from the functional perspective. The study was aimed to assess skeletal status of children suffering from CD with the use of muscle-bone functional algorithm. The study group comprised 29 celiac patients (13.7yr+/-2.9) on gluten-free diet (GFD), and 24 newly diagnosed atypical celiac patients, including subgroup with normal height (n=14; 12.6yr+/-3.9) and subgroup with short stature (n=10; 12.2yr+/-2.9). Muscular and skeletal status was evaluated by DXA (DPX-L, GE). Anthropometry, total body bone mineral density (TBBMD, g/cm(2)). and total body bone mineral content (TBBMC, g) as well as lean body mass (LBM, g) were evaluated. Muscle-bone interactions were estimated using TBBMC/LBM ratio. Previously established references for healthy controls were used for the calculation of Z-scores (age-matched) and SD-scores (height-matched). GFD treated celiacs and atypical celiacs with normal body height had TBBMD, TBBMC, LBM, and TBBMC/LBM ratio Z-scores and SD-scores within normal range for healthy controls. In contrary, atypical celiacs with short stature had significantly lower Z-scores for TBBMD (-2.3+/-0.4), TBBMC (-2.1+/-0.3), LBM (-1.4+/-0.3). and TBBMC/LBM ratio (-2.3+/-0.6) when compared to respective values observed in GFD treated celiacs (pnormal height (pvalues observed in GFD treated celiacs (+0.04+/-0.2; pnormal height (-0.4+/-0.2; pvalues of DXA assessed indicators of bone and muscle status as well as normal muscle-bone interactions. Untreated atypical celiacs may present a broad spectrum of heterogeneous abnormalities from normal to markedly

    KMeyeDB (http://mutview.dmb.med.keio.ac.jp/) is a database of human gene mutations that cause eye diseases. We have substantially enriched the amount of data in the database, which now contains information about the mutations of 167 human genes causing eye-related diseases including retinitis pigmentosa, cone-rod dystrophy, night blindness, Oguchi disease, Stargardt disease, macular degeneration, Leber congenital amaurosis, corneal dystrophy, cataract, glaucoma, retinoblastoma, Bardet-Biedl syndrome, and Usher syndrome. KMeyeDB is operated using the database software MutationView, which deals with various characters of mutations, gene structure, protein functional domains, and polymerase chain reaction (PCR) primers, as well as clinical data for each case. Users can access the database using an ordinary Internet browser with smooth user-interface, without user registration. The results are displayed on the graphical windows together with statistical calculations. All mutations and associated data have been collected from published articles. Careful data analysis with KMeyeDB revealed many interesting features regarding the mutations in 167 genes that cause 326 different types of eye diseases. Some genes are involved in multiple types of eye diseases, whereas several eye diseases are caused by different mutations in one gene.

    F-18 FDG-PET is useful for detection and staging of lymphoma. We investigated the prognostic significance of maximum standard uptake (maxSUV) value of FDG-PET for newly diagnosed lymphoma patients before chemotherapy. Twenty-seven patients (male: female = 17: 10: age: 49±19 years) with newly diagnosed lymphoma were enrolled. Nine-teen patients suffered from B cell lymphoma, 6 Hodgkins disease and 2 T cell lymphoma. One patient was stage I, 9 stage II, 3 stage III, 1 stage IV and 13 others. All patients underwent FDG-PET before initiation of chemotherapy. MaxSUV values using lean body weight were obtained for main and largest lesion to represent maxSUV of the patients. The disease progression was defined as total change of the chemotherapeutic regimen or addition of new chemotherapeutic agent during follow up period. The observed period was 389±224 days. The value of maxSUV ranged from 3 to 18 (mean±SD = 10.6±4.4). The disease progressions occurred in 6 patients. Using Cox proportional-hazard regression analysis, maxSUV was identified as a significant parameter for the disease progression free survival (p=0.044). Kaplan-Meier survival curve analysis revealed that the group with higher maxSUV (=10.6, n=5) suffered from shorter disease progression free survival (median 299 days) than the group with lower maxSUV (<10.6, n = 22) (median 378 days, p=0.0146). We found that maxSUV on pre-chemotherapeutic F-18 FDG-PET for newly diagnosed lymphoma patients is a significant parameter for disease progression. Lymphoma patients can be stratified before initiation of chemotherapy in terms of disease progression by the value of maxSUV 10.6

    Objective: To analyze the disease burden of violence in the Chinese population, in 1990 and 2013. Methods: Indicators including mortality rate, years of life lost due to premature mortality (YLL), years lived with disability (YLD), and disability-adjusted of life years (DALY) related to violence, were extracted from the Global Burden of Disease 2013 and used to describe the burden of disease caused by violence in the Chinese population. Data related to corresponding parameters on disease burden of violence in 1990 and 2013 were described. Results: In 2013, a total of 20 500 people died of violent events, with the death rate as 1.44 per 100 000, in China. DALY caused by violence was 1.08 million person years in 2013. DALY caused by sharp violence was 0.47 million person years, with 0.09 million person years lost due to firearm violence. Disease burden caused by violence appeared higher in males than in females. When comparing with data from the 1990s, reductions were seen by 67.35 % on the standardized death rate of violence, by 68.07 % on the DALY attributable to violence, and by 70.47 % on the standardized DALY rate attributable to violence, respectively, in 2013. Disease burden of violence among young adults and elderly was among the highest. When comparing with data from the 1990, DALY in 2013 decreased among all the age groups except for the 70-year-old showed an increase of 9.36 % . The standardized DALY rate in 2013 showed a declining trend in all the age groups, mostly in the 0-4-year-old group. The standardized DALY rates caused by sharp violence or firearm decreased by75.11 % and 83.20 % in the 0-4-year-old group. Conclusion: In recent years, the disease burden caused by violence showed a decreasing trend but appeared higher in males however with the increase of DALY in the elder population.

    Sexually transmitted diseases (STD) are a major health problem affecting mostly young people in both developing and developed countries. STD in women causes both acute morbidity and complications such as infertility, ectopic pregnancy, low-birth weight, and prematurity. The aim of the study is to assess the prevalence of bacterial vaginosis, vaginal candidiasis, and trichomoniasis among asymptomatic females attending STD outpatient department in a tertiary care hospital in South India. A retrospective analysis of data collected from clinical records of 3000 female patients of age 18 to 49 over a period of 12 months (July 2014 to June 2015) was carried out at the Institute of Venereology, Madras Medical College. Complete epidemiological, clinical, and investigational data were recorded and analyzed for the prevalence of bacterial vaginosis, vaginal candidiasis, and trichomoniasis among asymptomatic patients. About 48.37% (228/470) of bacterial vaginosis patients were asymptomatic. Nearly 45.38% (116/235) of vaginal candidiasis patients were asymptomatic and 30.35% (26/87) of trichomoniasis patients were asymptomatic. The above infections were common in the age group 25-35. Holistic screening protocol was incorporated for all female patients attending STD clinic even if asymptomatic and should be treated accordingly to prevent the acquisition of other serious sexually transmitted infections.

    Chronic kidney disease related-mineral bone disorder (CKD-MBD) has been poorly studied in pre-dialysis Indian CKD population. There are limited data on the pattern of these disturbances in diabetic CKD patients. Therefore, a study was conducted to find out the profile of mineral bone disorders in T2DM patients with pre-dialysis CKD. In this cross-sectional design, diabetic patients with newly-diagnosed stage 4 and 5 CKD were evaluated. Serum levels of calcium, phosphorus, intact parathyroid hormone (iPTH), 25 hydroxy vitamin D and total alkaline phosphatase (ALP) were measured in all patients. Bone mineral density (BMD) was measured using dual-energy X-ray absorptiometry (DXA). A total of 72 eligible patients participated (44 males, 28 females; age 54.2±11.7). Patients with CKD Stage 5 had a lower level of corrected serum calcium and significantly higher level of inorganic phosphorus, total ALP and iPTH as compared to stage 4 patients. Overall, 38.5% were hypocalcemic, 31.43% were hyperphosphatemic. 24.2% of CKD subjects were vitamin D deficient (110pg/ml) was detected in nearly 43% of patients. In stage 5, only 32% patients was found to have hyperparathyroidism (iPTH>300pg/ml). There was a good correlation between iPTH and total ALP (r=0.5, p=0.0001) in this cohort. 25 (OH) vitamin D was inversely correlated with ALP (r=-0.39, P=0.001) and showed negative correlation with urine ACR (r=-0.37, P=0.002). As a group, the osteoporotic CKD subjects exhibited higher iPTH (220.1±153.8 vs. 119±108pg/ml, p<0.05) as compared to those who were osteopenic or had normal bone density. There was significant correlation between BMD and iPTH (adjusted r=-0.436; P=0.001). In the multivariate regression model, we found intact PTH to predict BMD even after adjustment of all the confounders. The current study showed that adynamic bone disease is prevalent even in pre-dialysis CKD population. High bone turnover disease may not be the most prevalent type in diabetic CKD. However, it

If uncurbed, a new generation of "diseases of comfort" (such as those chronic diseases caused by obesity and physical inactivity) will become a major public health problem in this and the next century. To describe the concept, causes, and prevention and control strategies of diseases of comfort. Brokered by a senior research scientist specialised in knowledge translation, a chair, a president, and a past president of national public health associations contributed their views on the subject. Diseases of comfort have emerged as a price of living in a modern society. It is inevitable that these diseases will become more common and more disabling if human "progress" and civilisation continue toward better (more comfortable) living, without necessarily considering their effects on health. Modern technology must be combined with education, legislation, intersectoral action, and community involvement to create built and social environments that encourage, and make easy, walking, physical activity, and nutritious food choices, to reduce the health damaging effects of modern society for all citizens and not only the few. Public health needs to be more passionate about the health issues caused by human progress and adopt a health promotion stance, challenging the assumptions behind the notion of social "progress" that is giving rise to the burden of chronic disease and developing the skills to create more health promoting societies in which individual health thrives.

    The aim of the study was to evaluate systematic thyroid ultrasonography (US) relevance in newly diagnosed Graves' disease among patients presenting without palpable nodules. We consecutively recruited 208 cases of Graves' disease without palpable nodule. All patients were screened for thyroid antibodies and underwent a thyroid US. Ultrasonically guided biopsy was proposed for the assessment of all nodules upper or equal to 10mm in diameter. Two third of patients had an abnormal thyroid at palpation requiring an US. One third of patients had a normal thyroid at palpation and US was consequently unwarranted. Among all patients, US detected non-palpable nodules in 26% of cases. We found no smears suspected to be cancerous. In newly diagnosed Graves' disease, the US relevance is only questionable in patients without abnormal thyroid at palpation. Ultrasonography detected non-palpable nodules and none was suspected to be cancerous. These data suggest that US is not useful in patients without abnormal thyroid at palpation. Nevertheless, the recent Thyroid Imaging-Reporting And Data System classification (TI-RADS) might change our conclusions. The TI-RADS classification indeed improves the selection of nodules lower than 10mm in diameter requiring a biopsy. Nodules lower than 10mm in diameter were not biopsied in the present study. The other US data presented herein (echogenicity, vascularisation) provide no further relevance for systematic US in newly diagnosed patients. Copyright © 2014 Elsevier Masson SAS.

    BACKGROUND: Elevated levels of plasma C-reactive protein (CRP) have been associated with many diseases including depression, but it remains unclear whether this association is causal. We tested the hypothesis that CRP is causally associated with depression, and compared these results to those...... for cancer, ischemic heart disease, chronic obstructive pulmonary disease, and all-cause mortality. METHODS: We performed prospective and instrumental variable analyses using plasma CRP levels and four CRP genotypes on 78,809 randomly selected 20- to 100-year-old men and women from the Danish general...... population. End points included hospitalization or death with depression and somatic diseases, prescription antidepressant medication use, and all-cause mortality. RESULTS: A doubling in plasma CRP yielded an observed odds ratio (OR) of 1.28 (95% confidence interval [CI]: 1.23-1.33) for hospitalization...

  17. Taxonomy of Fungi Causing Mucormycosis and Entomophthoramycosis (Zygomycosis) and Nomenclature of the Disease: Molecular Mycologic Perspectives

    Science.gov (United States)

    2012-01-01

    Molecular phylogenetic analysis confirmed the phylum Zygomycota to be polyphyletic, and the taxa conventionally classified in Zygomycota are now distributed among the new phylum Glomeromycota and 4 subphyla incertae sedis (uncertain placement). Because the nomenclature of the disease zygomycosis was based on the phylum Zygomycota (Zygomycetes) in which the etiologic agents had been classified, the new classification profoundly affects the name of the disease. Zygomycosis was originally described as a convenient and inclusive name for 2 clinicopathologically different diseases, mucormycosis caused by members of Mucorales and entomophthoramycosis caused by species in the order Entomophthorales of Zygomycota. Without revision of original definition, the name “zygomycosis,” however, has more often been used as a synonym only for mucormycosis. This article reviews the progress and changes in taxonomy and nomenclature of Zygomycota and the disease zygomycosis. The article also reiterates the reasons why the classic names “mucormycosis” and “entomophthoramycosis” are more appropriate than “zygomycosis.” PMID:22247451

  18. Pulmonary Hypertension Due to Left Ventricular Cardiomyopathy: Is it the Result or Cause of Disease Progression?

    Adusumalli, Srinath; Mazurek, Jeremy A

    2017-12-01

    The purpose of this review is to define pulmonary hypertension in the setting of left heart disease (PH-LHD), discuss its epidemiology and pathophysiology, and highlight the cause and effect relationship it has with disease progression in the setting of cardiomyopathy. Both pulmonary hypertension (PH) and heart failure are becoming increasingly common. As such, PH-LHD is now the most common form of PH. The pathophysiology of the condition relates to backward transmission of elevated left ventricular filling pressures into the pulmonary circulation and, ultimately, right ventricular (RV) strain/dysfunction. It is evident that these pathophysiologic processes are both the effect and cause of left heart disease progression. In this review, we describe the complex relationship between disease progression in left ventricular cardiomyopathy and PH-LHD. Clinicians and researchers should take note of the importance of PH-LHD and RV dysfunction to appropriately risk stratify patients and develop therapies for the condition.

    Next-generation sequencing has greatly accelerated the search for disease-causing defects, but even for experts the data analysis can be a major challenge. To facilitate the data processing in a clinical setting, we have developed a novel medical resequencing analysis pipeline (MERAP). MERAP assesses the quality of sequencing, and has optimized capacity for calling variants, including single-nucleotide variants, insertions and deletions, copy-number variation, and other structural variants. MERAP identifies polymorphic and known causal variants by filtering against public domain databases, and flags nonsynonymous and splice-site changes. MERAP uses a logistic model to estimate the causal likelihood of a given missense variant. MERAP considers the relevant information such as phenotype and interaction with known disease-causing genes. MERAP compares favorably with GATK, one of the widely used tools, because of its higher sensitivity for detecting indels, its easy installation, and its economical use of computational resources. Upon testing more than 1,200 individuals with mutations in known and novel disease genes, MERAP proved highly reliable, as illustrated here for five families with disease-causing variants. We believe that the clinical implementation of MERAP will expedite the diagnostic process of many disease-causing defects. © 2014 WILEY PERIODICALS, INC.

    For a study of the natural history of coronary artery lesions after Kawasaki disease and their effect on myocardial blood flow reserve with exercise, five such patients underwent exercise testing on a bicycle. Oxygen consumption, carbon dioxide production, minute ventilation, and electrocardiograms were monitored continuously. Thallium-201 scintigraphy was performed for all patients. One patient stopped exercise before exhaustion of cardiovascular reserve but had no evidence of myocardial perfusion abnormalities. Four patients terminated exercise because of exhaustion of cardiovascular reserve; one had normal cardiovascular reserve and thallium scintiscans, but the remaining patients had diminished cardiovascular reserve. Thallium scintigrams showed myocardial ischemia in two and infarction in one. No patient had exercise-induced electrocardiographic changes. These results indicate that patients with residual coronary artery lesions after Kawasaki disease frequently have reduced cardiovascular reserve during exercise. The addition of thallium scintigraphy and metabolic measurements to exercise testing improved the detection of exercise-induced abnormalities of myocardial perfusion

    Ischaemic heart disease is the leading cause of mortality and morbidity and one of the primary causes of morbidity in Spain. The variability in the clinical presentation of this condition at both primary care and emergency services level requires a careful history and a thorough physical examination. In the case presented, the main symptoms of angina and dyspnea reported in the anamnesis, and the obvious pallor in the physical examination, were the key data to identify anaemia as a cause of angina.

    In Poland, as in most other European countries, diseases of the respiratory system are the 4th leading cause of mortality; they are responsible for about 8% of all deaths in the European Union (EU) annually. To assess the socio-economic aspects of mortality, it has become increasingly common to apply potential measures rather than conventionally used ratios. The aim of this study was to analyze years of life lost due to premature deaths caused by diseases of the respiratory system in Poland from 1999 to 2013. The study was based on a dataset of 5,606,516 records, obtained from the death certificates of Polish residents who died between 1999 and 2013. The information on deaths caused by diseases of the respiratory system, i.e., coded as J00-J99 according to the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10), was analyzed. The Standard Expected Years of Life Lost (SEYLL) indicator was used in the study. In the years 1999-2013, the Polish population suffered 280,519 deaths caused by diseases of the respiratory system (4.69% of all deaths). In the period analyzed, a gradual decrease in the standardized death rate was observed - from 46.31 per 100,000 inhabitants in 1999 to 41.02 in 2013. The dominant causes of death were influenza and pneumonia (J09-J18) and chronic lower respiratory diseases (J40-J47). Diseases of the respiratory system were the cause of 4,474,548.92 lost life years. The Standard Expected Years of Life Lost per person (SEYLLp) was 104.72 per 10,000 males and 52.85 per 10,000 females. The Standard Expected Years of Life Lost per death (SEYLLd) for people who died due to diseases of the respiratory system was 17.54 years of life on average for men and 13.65 years on average for women. The use of the SEYLL indicator provided significant information on premature mortality due to diseases of the respiratory system, indicating the fact that they play a large role in the health status of the Polish

    Kidney stones in patients with autosomal dominant polycystic kidney disease are common, regarded as the consequence of the combination of anatomic abnormality and metabolic risk factors. However, complete staghorn calculus is rare in polycystic kidney disease and predicts a gloomy prognosis of kidney. For general population, recent data showed metabolic factors were the dominant causes for staghorn calculus, but for polycystic kidney disease patients, the cause for staghorn calculus remained elusive. We report a case of complete staghorm calculus in a polycystic kidney disease patient induced by repeatedly urinary tract infections. This 37-year-old autosomal dominant polycystic kidney disease female with positive family history was admitted in this hospital for repeatedly upper urinary tract infection for 3 years. CT scan revealed the existence of a complete staghorn calculus in her right kidney, while there was no kidney stone 3 years before, and the urinary stone component analysis showed the composition of calculus was magnesium ammonium phosphate. UTI is an important complication for polycystic kidney disease and will facilitate the formation of staghorn calculi. As staghorn calculi are associated with kidney fibrosis and high long-term renal deterioration rate, prompt control of urinary tract infection in polycystic kidney disease patient will be beneficial in preventing staghorn calculus formation.

    In healthy sponges, microbes have been shown to account for up to 40 % of tissues. The majority of these are thought to originate from survivors evading digestion and immune responses of the sponge and growing and residing in the microenvironments of the mesophyll. Although a large percentage of these microbes are likely commensals, they may also include potentially pathogenic agents, which under specific conditions, such as temperature stress, may cause disease. Here we report a novel disease (sponge necrosis syndrome) that is severely affecting populations of the sponge Callyspongia ( Euplacella) aff biru. Both ITS fungal and 16S rDNA bacterial diversities were assessed in healthy and diseased individuals, highlighting six potential primary causal agents for this new disease: two bacteria, a Rhodobacteraceae sp. and a cyanobacterium, Hormoscilla spongeliae (formally identified as Oscillatoria spongeliae), and four fungi, a Ascomycota sp., a Pleosporales sp., a Rhabdocline sp., and a Clasosporium sp. Furthermore, histological analysis showed the dominance of fungal hyphae rather than bacteria throughout the disease lesion, which was absent or rare in healthy tissues. Inoculation trails showed that only a combination of one bacterium and one fungus could replicate the disease, fulfilling Henle-Koch's postulates and showing that this sponge disease is caused by a poly-microbial consortium.

    Celiac disease (CD), a malabsorption syndrome caused by hypersensitivity to gliadin fraction of gluten. CD can manifest with classic symptoms; however, significant myopathy and multiple fractures are rarely the predominant presentation of untreated celiac disease. Osteomalacia complicating celiac disease had become more and more rare. We describe here a case of osteomalacia secondary to a longstanding untreated celiac disease. This patient complained about progressive bone and muscular pain, weakness, fractures and skeletal deformities. Radiological and laboratory findings were all in favor of severe osteomalacia. Improvement of patient's weakness and laboratory abnormalities was obvious after treatment with gluten free diet, vitamin D, calcium and iron. This case affirms that chronic untreated celiac disease, can lead to an important bone loss and irreversible complications like skeletal deformities.

    Full Text Available Objectives & Methods: This suggestion was attempted to be elevated the recognition of common characteristics in disease. So, we performed to analyze the correlation of common cause of disease, characteristics of human body, and medical treatment. And the results are as follows. Results: 1. The cause of disease is consist of genetic factor, aging, habit, food of not good in health, weather, environment, deficit of the physical activity, stress and so on. 2. Generally, human has common and individual weakness. Individual weakness is appeared similar to the occurrence of volcano and lapse. 3. The correlation of disease and medical treatments is possible to explain using the quotation of the law of motion made by Isaac Newton, the great physicist. 4. When the process of the medical treatment was not progressed, the prognosis is determined by the correlation of the homeostasis(H' in human body and the homeostasis(H of disease. 5. The prognosis of disease is determined by the relationship between the energy of disease(F and medical treatment(F'. 6. The exact diagnosis is possible to predict the treatment sequence, and the facts that homeostasis in human body and disease, relationship between the energy of disease(F and medical treatment(F', action and reaction are important to determine the prognosis. 7. The careful observation of improving response and worsening action of disease becomes available for exact prognosis. Conclusion: The above described contents may be useful in clinical studies, and the concrete clinical reports about this will be made afterward.

    Betel nut (Areca nut) is the fruit of the Areca catechu tree. Approximately 700 million individuals regularly chew betel nut (or betel quid) worldwide and it is a known risk factor for oral cancer and esophageal cancer. We performed a meta-analysis to assess the influence of chewing betel quid on metabolic diseases, cardiovascular disease, and all-cause mortality. We searched Medline, Cochrane Library, Web of Science, and Science Direct for pertinent articles (including the references) published between 1951 and 2013. The adjusted relative risk (RR) and 95% confidence interval were calculated using the random effect model. Sex was used as an independent category for comparison. Of 580 potentially relevant studies, 17 studies from Asia (5 cohort studies and 12 case-control studies) covering 388,134 subjects (range: 94 to 97,244) were selected. Seven studies (N = 121,585) showed significant dose-response relationships between betel quid consumption and the risk of events. According to pooled analysis, the adjusted RR of betel quid chewers vs. non-chewers was 1.47 (PBetel quid chewing is associated with an increased risk of metabolic disease, cardiovascular disease, and all-cause mortality. Thus, in addition to preventing oral cancer, stopping betel quid use could be a valuable public health measure for metabolic diseases that are showing a rapid increase in South-East Asia and the Western Pacific.

    Public funding for medical research in Germany is primarily provided by the German Research Foundation (DFG) and the Federal Ministry of Education and Research (BMBF). The aim of this study was to analyze the amount of national public funding for medical research on predominant causes of death in Germany, cardiovascular diseases and neoplasms, in relation to the burden of these diseases in Germany. Three evaluators categorized medical research projects funded by the DFG or BMBF between 2010 and 2012 into the categories "Diseases of the circulatory system" (with subgroups "Ischemic heart diseases", "Heart failure" and "Cerebrovascular diseases") and "Neoplasms". The total amount of public funding by the national agencies was analyzed in relation to the burden of disease for the respective disease condition. Information on national public funding for medical research of 2091 million euros was available; of those, 246.8 million euros (11.8%) were categorized being spent for research on "Neoplasms", 118.4 million euros (5.7%) for research on "Diseases of the circulatory system". This results in 362.08 euros per case of death, 16.58 euros per year of life lost (YLL) and 16.04 euros per disability-adjusted life year (DALY) for "Neoplasms" and in 113.44 euros per case of death, 8.05 euros per YLL and 7.17 euros per DALY for "Diseases of the circulatory system". In Germany, research on cardiovascular diseases receives a lower share of national public funding for medical research compared to oncological research. These results are comparable to other European countries.

  1. Kufs disease, the major adult form of neuronal ceroid lipofuscinosis, caused by mutations in CLN6.

    LENUS (Irish Health Repository)

    Arsov, Todor

    2011-05-13

    The molecular basis of Kufs disease is unknown, whereas a series of genes accounting for most of the childhood-onset forms of neuronal ceroid lipofuscinosis (NCL) have been identified. Diagnosis of Kufs disease is difficult because the characteristic lipopigment is largely confined to neurons and can require a brain biopsy or autopsy for final diagnosis. We mapped four families with Kufs disease for whom there was good evidence of autosomal-recessive inheritance and found two peaks on chromosome 15. Three of the families were affected by Kufs type A disease and presented with progressive myoclonus epilepsy, and one was affected by type B (presenting with dementia and motor system dysfunction). Sequencing of a candidate gene in one peak shared by all four families identified no mutations, but sequencing of CLN6, found in the second peak and shared by only the three families affected by Kufs type A disease, revealed pathogenic mutations in all three families. We subsequently sequenced CLN6 in eight other families, three of which were affected by recessive Kufs type A disease. Mutations in both CLN6 alleles were found in the three type A cases and in one family affected by unclassified Kufs disease. Mutations in CLN6 are the major cause of recessive Kufs type A disease. The phenotypic differences between variant late-infantile NCL, previously found to be caused by CLN6, and Kufs type A disease are striking; there is a much later age at onset and lack of visual involvement in the latter. Sequencing of CLN6 will provide a simple diagnostic strategy in this disorder, in which definitive identification usually requires invasive biopsy.

    1981-01-01

    This paper contains the results of scintigraphical and puncture-cytological examinations carried out during an observation period of appr. 3 years on 548 patients with goiters from the Upper-Bavarien endemis region. In total, we had 484 thyroid gland scintigrams which showed 335 uninodular, 71 multinodular, and 78 diffuse goiters. The 335 solitary nodular goiters were allocated 278 cold, 36 warm, and 18 hot nodes; in three cases, the scintigram could not be assessed due to exogenous iodine contamination. In the 71 multinodular goiters, we found 118 cold, 28 warm, and 9 hot nodes. Cytological findings were established in 548 patients. In 484 cases, the findings were negative, in 19 cases suspicious, and in 17 cases positive. The efficiency of cytological diagnosis of malignant tumours can be stated to be 87.5%. The rate of falsely negative smears was 12.5%; cytologically, in 10.9% of the preparations falsely suspicious diagnoses were established, and in 1.6% the diagnoses were falsely positive.

    Strains of Neisseria meningitidis responsible for an epidemic of meningococcal disease occurring in Norway since the mid-1970s and for recent increases in the incidence of disease in several other parts of Europe have been identified by multilocus enzyme electrophoresis as members of a distinctive group of 22 closely related clones (the ET-5 complex). Clones of this complex have also colonized South Africa, Chile, Cuba, and Florida, where they have been identified as the causative agents of recent outbreaks of meningococcal disease. There is strong circumstantial evidence that outbreaks of disease occurring in Miami in 1981 and 1982 were caused in large part by bacteria that reached Florida via human immigrants from Cuba.

    Traffic air pollution has been linked to cardiovascular mortality, which might be due to co-exposure to road traffic noise. Further, personal and lifestyle characteristics might modify any association. We followed up 52 061 participants in a Danish cohort for mortality in the nationwide Register of Causes of Death, from enrollment in 1993-1997 through 2009, and traced their residential addresses from 1971 onwards in the Central Population Registry. We used dispersion-modelled concentration of nitrogen dioxide (NO₂) since 1971 as indicator of traffic air pollution and used Cox regression models to estimate mortality rate ratios (MRRs) with adjustment for potential confounders. Mean levels of NO₂ at the residence since 1971 were significantly associated with mortality from cardiovascular disease (MRR, 1.26; 95% confidence interval [CI], 1.06-1.51, per doubling of NO₂ concentration) and all causes (MRR, 1.13; 95% CI, 1.04-1.23, per doubling of NO₂ concentration) after adjustment for potential confounders. For participants who ate fruit and vegetables per day, the MRR was 1.45 (95% CI, 1.13-1.87) for mortality from cardiovascular disease and 1.25 (95% CI, 1.11-1.42) for mortality from all causes. Traffic air pollution is associated with mortality from cardiovascular diseases and all causes, after adjustment for traffic noise. The association was strongest for people with a low fruit and vegetable intake.

  6. Alterations and diseases of the gastrointestinal tract caused by old age

    The dissertation reviews the publications on 'The gastrointestinal tract in old age' since 1941. As in the 1941 publication by Heinrich, particular interest is taken in diagnostic radiology. The lower age limit of the cases described was set at 55 to 60 years. Oesophageal changes ranged from functional disturbances (e.g. atonia, changes in peristalsis, or dilatation) to chronic inflammation, displacement caused by the surrounding organs, and tumours (mainly carcinoma). Formation of diverticula takes an intermediate position. Of the gastric and duodenal changes, hiatal hermia and chronic atrophic gastritis were the most frequent. Ulcers caused by old age differ from 'common' ulcers in some respects, and the symptoms may be confused with those of gastric carcinoma. Early gastric carcinoma is another disease whose incidence increases with age. Thoracic and spinal changes may cause impressions on the stomach. The effects of old age on the time of passage of contrast media, on gastric tone, and on the shape of the stomach remain unclear. Changes caused by old age in the small and large intestine range from formation of diverticula and vascular diseases (e.g. ischaemic colitis and obstruction of the mesenteric vessels) to the frequent carcinoma of the large intestine and rectum. According to this study it has to be supposed that the degenerative atrophic processes of aging and previous diseases occurring increasingly in old age, favour the provocation of ratrogenic injuries.

    Objective: To investigate complications and causes of thyroid arterial embolization for hyperthyroidism caused by Graves' disease. Methods: Twenty-eight patients with hyperthyroidism caused by Graves' disease had been treated through transcathter arterial embolization with mid-term follow up. The thyroid angiography, interventional treatment, complications and causes were investigated. Results Followed up for over one year (12-24 months), mid-term rate of efficiency was 78.6% with recurrent rate of one year being 14.2%. Two patients (7.1%) had brain infarction with one partially recovered after proper therapy and the other died due to subsequent hyperthyroidism crisis. One case had temporary hypothyroidism, and another hypoparathyroidism but no permanent hypothyroidism or hypoparathyroidism occurred. One patient suffered relatively severe post-embolization syndrome. All the other complications disappeared after proper treatment. Followed up for more than a year, no other complications occurred. Conclusion: Misembolization due to regurgitation of embolized agent is one of the most important factors leading to complications of arterial embolization for Graves' disease. In order to reduce complications and improve therapeutic efficacy, it is essential to superselectively catheterize the thyroid, avoid dangerous anastomose, prevent regurgitation misembolization and strictly operate under fluoroscopy.

    In recent years, claims have proliferated in cyberspace that wind turbines cause a large variety of symptoms and diseases. One of these, "vibroacoustic disease" (VAD) is frequently mentioned. The aim of this study is to examine the quality of the evidence on how VAD came to be associated with wind turbine exposure by wind farm opponents. Searches of the web (Google advanced) and major research databases for papers on VAD and wind turbines. Self-citation analysis of research papers on VAD. Google returned 24,700 hits for VAD and wind turbines. Thirty-five research papers on VAD were found, none reporting any association between VAD and wind turbines. Of the 35 papers, 34 had a first author from a single Portuguese research group. Seventy-four per cent of citations to these papers were self-citations by the group. Median self-citation rates in science are around 7%. Two unpublished case reports presented at conferences were found asserting that VAD was "irrefutably demonstrated" to be caused by wind turbines. The quality of these reports was abject. VAD has received virtually no scientific recognition beyond the group who coined and promoted the concept. There is no evidence of even rudimentary quality that vibroacoustic disease is associated with or caused by wind turbines. The claim that wind turbines cause VAD is a factoid that has gone 'viral' in cyberspace and may be contributing to nocebo effects among those living near turbines. © 2013 The Authors.

    Stroke mortality estimates in the Global Burden of Disease (GBD) study are based on routine mortality statistics and redistribution of ill-defined codes that cannot be a cause of death, the so-called 'garbage codes' (GCs). This study describes the contribution of these codes to stroke mortality estimates. All available mortality data were compiled and non-specific cause codes were redistributed based on literature review and statistical methods. Ill-defined codes were redistributed to their specific cause of disease by age, sex, country and year. The reassignment was done based on the International Classification of Diseases and the pathology behind each code by checking multiple causes of death and literature review. Unspecified stroke and primary and secondary hypertension are leading contributing 'GCs' to stroke mortality estimates for hemorrhagic stroke (HS) and ischemic stroke (IS). There were marked differences in the fraction of death assigned to IS and HS for unspecified stroke and hypertension between GBD regions and between age groups. A large proportion of stroke fatalities are derived from the redistribution of 'unspecified stroke' and 'hypertension' with marked regional differences. Future advancements in stroke certification, data collections and statistical analyses may improve the estimation of the global stroke burden. © 2015 S. Karger AG, Basel.

    Full Text Available IgG4-related disease (IgG4-RD is a recently recognized disease entity. A 74-year-old male presented with transient headache. He was diagnosed IgG4-RD by pancreatic biopsy at the age of 72. Magnetic Resonance Imaging (MRI showed disseminated cerebral microbleeds and microinfarctions in time and space. It suggested cerebral vasculitis, however any causative factor were not confirmed. IgG4-RD rarely causes cerebral vasculitis. This might be a first case of an asymptomatic cerebral vasculitis due to IgG4-RD. Patient was started on oral prednisolone, and no neurological or neuropsychological symptom was clinically observed. The MRI findings improved after treatment, and revealed no indication of newly lesions at 6-months follow-up. Early treatment for IgG4-RD may be recommended to prevent irreversible cognitive dysfunction. Keywords: IgG4-related disease, Treatment, Cerebral vasculitis

    Full Text Available Introduction : The prevalence of nutritional status disorders in children with ulcerative colitis (UC is much lower than in the case of Crohn’s disease (CD. The largest variability in the components of body composition occurs at the time of a new diagnosis and in periods of disease exacerbation. Aim: Assessment of body composition in children with UC and CD. Material and methods: The preliminary study included 59 children with inflammatory bowel disease (IBD (34 children with UC vs. 25 children with CD aged 4–18 years. The final analysis included 26 newly diagnosed children (16 children with UC vs. 10 children with CD. The evaluation of body composition was conducted by means of BIA-101 bioimpedance analyser. Results : Decreased values of lean mass were found in children with newly diagnosed IBD (UC: 41.13 kg vs. control group: 42.06 kg; CD: 35.50 kg vs. control group: 45.50 kg. After a year interval, an increase in fat (UC 1: 7.67 kg vs. UC 2: 10.33 kg; CD 1: 7.36 kg vs. CD 2: 9.47 kg as well as lean body mass (UC 1: 35.22 kg vs. UC 2: 39.00 kg; CD 1: 35.99 kg vs. CD 2: 42.41 kg was found in children. Conclusions : Children with newly diagnosed IBD were highly vulnerable to nutritional status disturbances. The increase in fat and lean body mass in an annual interval may be due to the treatment regime and control of the children.

    The authors report clinical features and therapeutic response of 24 outpatients with acute Chagas' disease, and 3 in the initial chronic phase, referred to the Clinic for Infectious and Parasitic Diseases of the FMUSP "Clínicas" Hospital between 1974 and 1987. The following transmission routes were involved: triatominae in 7 cases, blood transfusion in 9, kidney transplantation and/or blood transfusion in 4, accidental in 1, oral route in 3, probably breast feeding in 1, congenital or breast feeding in 1, and congenital or blood transfusion in 1. Six patients infected by triatominac acquired the disease between 1974 and 1980 and one in 1987. The blood transfusion infected patients acquired the disease in Greater São Paulo, seven of whom after 1983. The acute phase Chagas' disease was oligosymptomatic in 4 patients: three of such patients being immunocompromised by drugs or other diseases. Another two adult immunocompromised patients developed myocarditis and congestive heart failure. Clinical features were severe in 5 from 6 children under two years, irrespective of the transmission route. Evaluation of the acute phase patients treated with benznidazol (4-10 mg/kg/day) showed: therapeutic failure in 4/16 (25.0%); possible cure in 9/16 (53.2%) and inconclusive results in 3/16 (18.8%). The antibody and complement-mediated lysis reaction was in keeping with the xenodiagnosis in 18/22 cases, having shown negative results after treatment earlier than classical serological reactions. One aplastic anaemia patient receiving corticosteroid presented lymphoproliferative disease 6 years after being treated with benznidazol for acute Chagas' disease.

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

    The proportion of deaths attributed to hypertensive diseases (HYPDs) was only 50% of that registered for cerebrovascular diseases (CBVDs) in 2013 in Brazil. This article aims to evaluate mortality related to HYPDs and CBVDs as multiple causes of death, in Brazil from 2004 to 2013. Analysis of historical series of secondary data obtained from Brazilian official registries. Data about the deaths were obtained from the Mortality Information System of the Brazilian Ministry of Health, available on the DATASUS website. CBVDs and HYPDs were evaluated according to their mentions as the underlying cause of death or entry in any line of the death certificates (DCs), according to their International Statistical Classification of Diseases and Related Health Problems, 10th Revision codes. When CBVDs were the underlying causes of death, HYPDs were mentioned in 40.9% of the DCs. When HYPDs were the underlying causes of death, CBVDs were mentioned in only 5.0%. When CBVDs were mentioned without HYPDs, they were selected as the underlying cause of death 74.4% of the time. When HYPDs were mentioned in DCs without CBVDs, HYPDs were selected 30.0% of the time. In 2004, the frequency of any mention of HYPDs relative to the frequency of HYPDs cited as underlying causes increased fourfold and was followed by a plateau until 2013. In contrast, the frequency of any mention of CBVDs relative to the frequency of CBVDs as underlying causes decreased in the same period. Because this study was based on DC records, it was limited by the way these documents were completed, which may have included lack of record of the causes related to the sequence that culminated in death. When deaths related to HYPDs were evaluated as multiple causes of death, they were mentioned up to four times more often than when they were selected as underlying causes of death. This reinforces the need for better control of hypertension to prevent deaths. Copyright © 2018 The Royal Society for Public Health. Published by

    Nax os disease is a rare hereditary disorder characterized by palmoplantar keratoderma, woolly hair and cardiomyopathy. This study aims to determine whether Naxos disease in a Saudi Arab family is caused by the Pk2157del2 mutation that was identified in Greek families from Naxos Island where the disease had originally been described. This study was undertaken at King Fahad Hospital of the University, Al-Khobar, and the Medical University of Hannover, in the spring of 2003. Naxos disease has been encountered in a 2-year-old girl and her 30-year-old aunt of a Saudi Arab family. Deoxyribonucleic acid samples of this family were analyzed by polymerase chain-reaction (PCR) amplification of the respective region of the plakoglobin gene, and direct nucleotide sequencing of the PCR-products. Segregation analysis was performed employing the newly detected IVS11+22G/A polymorphism. Molecular genetic analysis of the DNA sample of the child diagnosed with Naxos disease showed absence of the Pk2157del2 mutation. In addition, the segregation analysis revealed heterozygosity for IVS11+22G/A in the affected girl. Absence of the Pk2157del2 frameshift in the affected child proved that Naxos disease in this Saudi Arab family is not caused by the same mutation that was identified in the Greek families. Furthermore, heterozygosity for the IVS11+22G/A polymorphism provided evidence for exclusion of the plakoglobin gene in this consanguineous family. (author)

  19. How Do the Virulence Factors of Shigella Work Together to Cause Disease?

    Science.gov (United States)

    Mattock, Emily; Blocker, Ariel J

    2017-01-01

    Shigella is the major cause of bacillary dysentery world-wide. It is divided into four species, named S. flexneri, S. sonnei, S. dysenteriae , and S. boydii , which are distinct genomically and in their ability to cause disease. Shigellosis, the clinical presentation of Shigella infection, is characterized by watery diarrhea, abdominal cramps, and fever. Shigella 's ability to cause disease has been attributed to virulence factors, which are encoded on chromosomal pathogenicity islands and the virulence plasmid. However, information on these virulence factors is not often brought together to create a detailed picture of infection, and how this translates into shigellosis symptoms. Firstly, Shigella secretes virulence factors that induce severe inflammation and mediate enterotoxic effects on the colon, producing the classic watery diarrhea seen early in infection. Secondly, Shigella injects virulence effectors into epithelial cells via its Type III Secretion System to subvert the host cell structure and function. This allows invasion of epithelial cells, establishing a replicative niche, and causes erratic destruction of the colonic epithelium. Thirdly, Shigella produces effectors to down-regulate inflammation and the innate immune response. This promotes infection and limits the adaptive immune response, causing the host to remain partially susceptible to re-infection. Combinations of these virulence factors may contribute to the different symptoms and infection capabilities of the diverse Shigella species, in addition to distinct transmission patterns. Further investigation of the dominant species causing disease, using whole-genome sequencing and genotyping, will allow comparison and identification of crucial virulence factors and may contribute to the production of a pan- Shigella vaccine.

    An outbreak of a new disease occurred in cotton (Gossypium hirsutum) fields in northwest Argentina starting in the 2009-10 growing season and is still spreading steadily. The characteristic symptoms of the disease included slight leaf rolling and a bushy phenotype in the upper part of the plant. In this study, we determined the complete nucleotide sequences of two independent virus genomes isolated from cotton blue disease (CBD)-resistant and -susceptible cotton varieties. This virus genome comprised 5,866 nucleotides with an organization similar to that of the genus Polerovirus and was closely related to cotton leafroll dwarf virus, with protein identity ranging from 88 to 98%. The virus was subsequently transmitted to a CBD-resistant cotton variety using Aphis gossypii and symptoms were successfully reproduced. To study the persistence of the virus, we analyzed symptomatic plants from CBD-resistant varieties from different cotton-growing fields between 2013 and 2015 and showed the presence of the same virus strain. In addition, a constructed full-length infectious cDNA clone from the virus caused disease symptoms in systemic leaves of CBD-resistant cotton plants. Altogether, the new leafroll disease in CBD-resistant cotton plants is caused by an atypical cotton leafroll dwarf virus.

    The tulip tree (Liriodendron chinense) has been widely cultivated in Korea as a street or garden tree for its large flowers, which have a superficial resemblance to tulips. Occurrence of anthracnose disease on the leaves of tulip trees growing on the campus of Gyeongsang National University, Jinju, Korea, has been observed. Based on mycological characteristics, pathogenicity, and internal transcribed spacer sequence, the causal fungus was identified as Colletotrichum gloeosporioides. This is the first report on anthracnose disease caused by C. gloeosporioides on tulip trees in Korea.

However, its link to mortality due to other causes is less clear.We studied 367,932 adults (20-93 years old in the Korean Heart Study (baseline between 1996-2004 and follow-up until 2011 and assessed the associations of creatinine-based eGFR and dipstick proteinuria with mortality due to CVD (1,608 cases, cancer (4,035 cases, and other (non-CVD/non-cancer causes (3,152 cases after adjusting for potential confounders.Although cancer was overall the most common cause of mortality, in participants with chronic kidney disease (CKD, non-CVD/non-cancer mortality accounted for approximately half of cause of death (47.0%for eGFR <60 ml/min/1.73 m2 and 54.3% for proteinuria ≥1+. Lower eGFR (<60 vs. ≥60 ml/min/1.73 m2 was significantly associated with mortality due to CVD (adjusted hazard ratio 1.49 [95% CI, 1.24-1.78] and non-CVD/non-cancer causes (1.78 [1.54-2.05]. The risk of cancer mortality only reached significance at eGFR <45 ml/min/1.73 m2 when eGFR 45-59 ml/min/1.73 m2 was set as a reference (1.62 [1.10-2.39]. High proteinuria (dipstick ≥1+ vs. negative/trace was consistently associated with mortality due to CVD (1.93 [1.66-2.25], cancer (1.49 [1.32-1.68], and other causes (2.19 [1.96-2.45]. Examining finer mortality causes, low eGFR and high proteinuria were commonly associated with mortality due to coronary heart disease, any infectious disease, diabetes, and renal failure. In addition, proteinuria was also related to death from stroke, cancers of stomach, liver, pancreas, and lung, myeloma, pneumonia, and viral hepatitis.Low eGFR was associated with CVD and non-CVD/non-cancer mortality, whereas higher proteinuria was consistently related to mortality due to CVD, cancer, and other causes. These findings suggest the need for multidisciplinary prevention and management strategies in individuals with CKD

    Severe hypertriglyceridemia is a condition associated with extremely high triglycerides (TG) plasma concentrations exceeding 1000mg/dl. This condition may result in mutations in genes encoding lipoprotein lipase (LPL), apolipoprotein C2 (APOC2) and apolipoprotein A5 (APOA5) characterized by an autosomal recessive inheritance pattern. A case report of a patient in which clinical picture of type 1 diabetes mellitus (T1DM) was accompanied by diabetic ketoacidosis (DKA) and severe hypertriglyceridemia. A 2.5-year-old boy was admitted to the hospital with ketoacidosis (pH - 7.0, BE - 20mmol/l, HCO3 10mmol/l), glucose level of 850mg%, hyponatremia (Na 100mmol/l) and hyperlipidemia (TG 13493 mg/dl, TC 734 mg/dl). The administered treatment resulted in nearly normal glycemic values and lipid disturbances normalization. This child was diagnosed with a heterozygous mutation of the LPL gene. Currently with an intensive insulin therapy and correct metabolic control of type 1 diabetes mellitus (T1DM), this patient maintains a normal lipid profile. In patient with T1DM the diagnosis of severe hypertriglyceridemia in the course of ketoacidosis should be based on careful interpretation of laboratory tests results. Moreover genetic tests of the patient and his/her immediate relatives blood samples should be performed. © Polish Society for Pediatric Endocrinology and Diabetology.

    To evaluate the association between coffee consumption and mortality from all causes and from cardiovascular disease. Data from the Aerobics Center Longitudinal Study representing 43,727 participants with 699,632 person-years of follow-up were included. Baseline data were collected by an in-person interview on the basis of standardized questionnaires and a medical examination, including fasting blood chemistry analysis, anthropometry, blood pressure, electrocardiography, and a maximal graded exercise test, between February 3, 1971, and December 30, 2002. Cox regression analysis was used to quantify the association between coffee consumption and all-cause and cause-specific mortality. During the 17-year median follow-up, 2512 deaths occurred (804 [32%] due to cardiovascular disease). In multivariate analyses, coffee intake was positively associated with all-cause mortality in men. Men who drank more than 28 cups of coffee per week had higher all-cause mortality (hazard ratio [HR], 1.21; 95% CI, 1.04-1.40). However, after stratification based on age, younger (coffee consumption (>28 cups per week) and all-cause mortality after adjusting for potential confounders and fitness level (HR, 1.56; 95% CI, 1.30-1.87 for men; and HR, 2.13; 95% CI, 1.26-3.59 for women). In this large cohort, a positive association between coffee consumption and all-cause mortality was observed in men and in men and women younger than 55 years. On the basis of these findings, it seems appropriate to suggest that younger people avoid heavy coffee consumption (ie, averaging >4 cups per day). However, this finding should be assessed in future studies of other populations. Copyright © 2013 Mayo Foundation for Medical Education and Research. Published by Elsevier Inc. All rights reserved.

    Purpose To compare the diagnostic performances of contrast material-enhanced spectral mammography and breast magnetic resonance (MR) imaging in the detection of index and secondary cancers in women with newly diagnosed breast cancer by using histologic or imaging follow-up as the standard of reference. Materials and Methods This institutional review board-approved, HIPAA-compliant, retrospective study included 52 women who underwent breast MR imaging and contrast-enhanced spectral mammography for newly diagnosed unilateral breast cancer between March 2014 and October 2015. Of those 52 patients, 46 were referred for contrast-enhanced spectral mammography and targeted ultrasonography because they had additional suspicious lesions at MR imaging. In six of the 52 patients, breast cancer had been diagnosed at an outside institution. These patients were referred for contrast-enhanced spectral mammography and targeted US as part of diagnostic imaging. Images from contrast-enhanced spectral mammography were analyzed by two fellowship-trained breast imagers with 2.5 years of experience with contrast-enhanced spectral mammography. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value were calculated for both imaging modalities and compared by using the Bennett statistic. Results Fifty-two women with 120 breast lesions were included for analysis (mean age, 50 years; range, 29-73 years). Contrast-enhanced spectral mammography had similar sensitivity to MR imaging (94% [66 of 70 lesions] vs 99% [69 of 70 lesions]), a significantly higher PPV than MR imaging (93% [66 of 71 lesions] vs 60% [69 of 115 lesions]), and fewer false-positive findings than MR imaging (five vs 45) (P contrast-enhanced spectral mammography depicted 11 of the 11 secondary cancers (100%) and MR imaging depicted 10 (91%). Conclusion Contrast-enhanced spectral mammography is potentially as sensitive as MR imaging in the evaluation of extent of disease in newly diagnosed

    AbstractContext: Aggressive pituitary tumours causing Cushing's Disease are very rare, difficult to treat, and usually resistant to conventional therapy. There is growing evidence for the use of temozolomide (TZM), an alkylating chemotherapeutic agent, as first line chemotherapy in tumours resistant to repeated neurosurgery, radiotherapy and adrenalectomy. To present the response to TMZ in a rare case of an aggressive pituitary tumour in the course of Cushing's Disease and to review the literature referring to similar cases. In this report, we present the case of a 61 year old male patient who was diagnosed with Cushing's Disease in the course of a pituitary invasive macroadenoma in 2011. The patient underwent 4 transphenoidal non-radical neurosurgeries (2012,2013) with rapid tumour progression, repeated non-radical bilateral adrenalectomy (2012, 2013) and stereotactic radiotherapy, and gamma knife surgery (2013, 2015). Histopathological examination revealed macroadenoma with high cell polymorphism and the presence of Crooke's cells, Ki-<2%. Since 2015 the patient has been treated with 6 cycles of TMZ (320 mg per day for 5 consecutive days, 28-day cycle) with clinical and biochemical improvement and stabilized tumour size and no side effects. TMZ was continued for up to 9 cycles with a stable serum level of cortisol and ACTH being observed. However, clinical symptoms like headaches, visual field impairment, and finally hearing loss started to progress from the eighth cycle. After the ninth cycle of TMZ, there was a sudden increase in the size of the tumour, impairment of the cortisol and ACTH level, marked deterioration of the clinical status with the recurrence of severe headaches, narrowing of the visual field and hearing loss. At the beginning of 2016, a sudden clinical status and sight deterioration, strong headaches, drop of the right eyelid with widening of the pupil were observed. The patient died in February 2016. The case of our patient suggests that the

    Full Text Available Abstract Background Related species, such as humans and chimpanzees, often experience the same disease with varying degrees of pathology, as seen in the cases of Alzheimer's disease, or differing symptomatology as in AIDS. Furthermore, certain diseases such as schizophrenia, epithelial cancers and autoimmune disorders are far more frequent in humans than in other species for reasons not associated with lifestyle. Genes that have undergone positive selection during species evolution are indicative of functional adaptations that drive species differences. Thus we investigate whether biomedical disease differences between species can be attributed to positively selected genes. Results We identified genes that putatively underwent positive selection during the evolution of humans and four mammals which are often used to model human diseases (mouse, rat, chimpanzee and dog. We show that genes predicted to have been subject to positive selection pressure during human evolution are implicated in diseases such as epithelial cancers, schizophrenia, autoimmune diseases and Alzheimer's disease, all of which differ in prevalence and symptomatology between humans and their mammalian relatives. In agreement with previous studies, the chimpanzee lineage was found to have more genes under positive selection than any of the other lineages. In addition, we found new evidence to support the hypothesis that genes that have undergone positive selection tend to interact with each other. This is the first such evidence to be detected widely among mammalian genes and may be important in identifying molecular pathways causative of species differences. Conclusion Our dataset of genes predicted to have been subject to positive selection in five species serves as an informative resource that can be consulted prior to selecting appropriate animal models during drug target validation. We conclude that studying the evolution of functional and biomedical disease differences

    Out-of-pocket (OOP) medical expenses often lead to catastrophic expenditure and impoverishment in low- and middle-income countries. Yet, there has been no systematic examination of which specific diseases and conditions (e.g., tuberculosis, cardiovascular disease) drive medical impoverishment, defined as OOP direct medical costs pushing households into poverty. We used a cost and epidemiological model to propose an assessment of the burden of medical impoverishment in Ethiopia, i.e., the number of households crossing a poverty line due to excessive OOP direct medical expenses. We utilized disease-specific mortality estimates from the Global Burden of Disease study, epidemiological and cost inputs from surveys, and secondary data from the literature to produce a count of poverty cases due to OOP direct medical costs per specific condition. In Ethiopia, in 2013, and among 20 leading causes of mortality, we estimated the burden of impoverishment due to OOP direct medical costs to be of about 350,000 poverty cases. The top three causes of medical impoverishment were diarrhea, lower respiratory infections, and road injury, accounting for 75 % of all poverty cases. We present a preliminary attempt for the estimation of the burden of medical impoverishment by cause for high mortality conditions. In Ethiopia, medical impoverishment was notably associated with illness occurrence and health services utilization. Although currently used estimates are sensitive to health services utilization, a systematic breakdown of impoverishment due to OOP direct medical costs by cause can provide important information for the promotion of financial risk protection and equity, and subsequent design of health policies toward universal health coverage, reduction of direct OOP payments, and poverty alleviation.

  15. The causes of skin damage and leg ulceration in chronic venous disease.

    Chronic venous disease with skin changes of the leg is a common condition affecting up to 1 in 20 people in westernized countries. The causes of this problem are not fully understood, although research in recent years has revealed a number of important mechanisms that contribute to the disease process. Patients with chronic venous disease suffer persistently raised pressures in their deep and superficial veins in the lower limb. Leucocytes become "trapped" in the circulation of the leg during periods of venous hyper-tension produced by sitting or standing. Studies of the plasma levels of neutrophil granule enzymes shows that these are increased during periods of venous hypertension, suggesting that this causes activation of the neutrophils. Investigation of the leucocyte surface ligands CD11b and CD62L shows that the more activated neutrophils and monocytes are sequestered during venous hypertension. Measurement of plasma levels of the soluble parts of the endothelial adhesion molecules VCAM, ICAM, and ELAM show that these are all elevated in patients with chronic venous disease compared to controls. Following 30 minutes of venous hypertension produced by standing, these levels are further increased. These data suggest that venous hypertension causes neutrophil and monocyte activation, which in turn causes injury to the endothelium. Chronic injury to the endothelium leads to a chronic inflammatory condition of the skin that we know clinically as lipodermatosclerosis. This is mediated by perivascular inflammatory cells, principally macrophages, in the skin microcirculation. These stimulate fibroblasts in the skin leading to tissue remodeling and laying down of fibrous tissue. Vascular endothelial growth factor stimulates proliferation of capillaries within the skin. Skin in this state has the potential to ulcerate in response to minor injury.

    This editorial briefly reviews studies which might answer the question as to whether radioiodine treatment causes the ophthalmopathy of Graves' disease. However, the data do not allow any conclusion one way or the other. Other possible causal factors are discussed. Further studies are required to define whether treatment of hyperthyroidism aggravates the ophthalmopathy and whether one thereby is worse than the others and by how much. (UK).

    During its earliest stage, before cell loss and independent of amyloid plaques and neurofibrillary tangles, Alzheimer's disease (AD) causes synaptic loss affecting the basal functional properties of neurons. In principle, synaptic loss can be detected by measuring AD-induced changes in basal function, or by measuring stimulus-evoked responses on top of basal changes. Functional magnetic resonance imaging (fMRI) is sensitive to both basal changes and evoked-responses, and there are therefore t...

  19. Fluoride Exposure in Early Life as the Possible Root Cause of Disease In Later Life.

    Fluoride, one of the most celebrated ingredients for the prevention of dental caries in the 20th century, has also been controversial for its use in dentifrices and other applications. In the current review, we have concentrated primarily on early-life exposure to fluoride and how it may affect the various organs. The most recent controversial aspects of fluoride are related to toxicity of the developing brain and how it may possibly result in the decrease of intelligence quotient (IQ), autism, and calcification of the pineal gland. In addition, it has been reported to have possible effects on bone and thyroid glands. If nutritional stress is applied during a critical period of growth and development, the organ(s) and/or body will never recover once they pass through the critical period. For example, if animals are force-fed during experiments, they will simply get fat but never reach the normal size. Although early-life fluoride exposure causing fluorosis is well reported in the literature, the dental profession considers it primarily as an esthetic rather than a serious systemic problem. In the current review, we wanted to raise the possibility of future disease as a result of early-life exposure to fluoride. It is not currently known how fluoride will become a cause of future disease. Studies of other nutritional factors have shown that the effects of early nutritional stress are a cause of disease in later life.

    Full Text Available Gaucher disease (OMIM #230800 is caused by β-glucosidase deficiency and primarily involves the mononuclear phagocyte system (also called Reticuloendothelial System or Macrophage System. The disease is classified into three main phenotypes based on the presence or absence of neurological manifestations: non-neuronopathic (type 1, acute neuronopathic (type 2 and chronic neuronopathic (type 3. Typical manifestations include hepatosplenomegaly, skeletal deformities, hematological abnormalities, interstitial lung fibrosis and neurodegeneration in neuronopathic cases. Mesenteric lymphadenopathy with resultant protein losing enteropathy (PLE has only been rarely described. Mesenteric lymphadenopathy may lead to intestinal lymphatic obstruction and secondary lymphangiectasia resulting in chronic diarrhea, abdominal pain and weight loss. Fecal protein loss with secondary hypoalbuminemia can be significant. We report a male with Chronic Neuronopathic Gaucher disease (GD (homozygous for c.1448T>C (NM_000157.3 GBA mutation who at 16 years of age developed intractable abdominal pain, diarrhea and weight loss. This was caused by PLE secondary to intestinal lymphangiectasia caused by calcified mesenteric lymphadenopathy despite prior long term enzyme replacement therapy (ERT and/or substrate reduction therapy (SRT. His older similarly affected sister who had been receiving treatment with ERT and/or SRT remains stable on these treatments with no evidence of mesenteric lymphadenopathy. Medical management with total parenteral nutrition, daily medium chain triglyceride-oil (MCT supplementation, low dose oral budesonide, continued oral SRT and an increased dose of parenteral ERT has stabilized his condition with resolution of the gastrointestinal symptoms and appropriate weight gain.
