    The objective of this paper is to compare disease activity and clinical features at diagnosis in male and female patients with systemic lupus erythematosus (SLE). This was a cross-sectional study in which every male patient (n = 40) was matched with three female patients of the same age (±5 years) and racial/ethnic group; disease activity as per the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and disease manifestations at the time of diagnosis were compared. Alopecia and anti-Ro antibodies were more frequent in female patients. No statistically significant difference in any other disease characteristics was found. However, male gender was associated with a risk of severe disease activity at the time of diagnosis (as determined by SLEDAI ≥12 score) independent of age, racial/ethnic group, anti-Ro positivity or time to criteria accrual (OR: 3.11 95% CI, 1.09-8.92; p = 0.035). In newly diagnosed SLE patients, male gender is associated with higher disease activity despite the fact that male and female patients seem to experience similar overall disease manifestations. © The Author(s) 2016.

    Behçet's disease is an autoimmune systemic vasculitis that can occur after exposure to infectious agents. Behçet's disease also has been associated with HIV infection, including de novo development of this condition during chronic HIV infection and resolution of Behçet's disease symptoms following initiation of antiretroviral therapy. We describe a patient who presented with systemic vasculitis with skin and mucous membrane ulcerations in the setting of acute HIV infection, who was eventually diagnosed with Behçet's disease, demonstrating a possible link between acute HIV infection, immune activation and development of autoimmunity. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    delivering live calves (499.3 ± 16.2 vs. 461.3 ± 4.1 arbitrary unit). 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.

    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.

    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.

    It is important to distinguish between diverticulosis, the presence of asymptomatic diverticula, and diverticular disease which refers to symptomatic cases which can present with acute or chronic symptoms. Chronic symptoms range from mild intermittent abdominal cramps to the more severe picture of chronic abdominal pain and occasional rectal bleeding. In contrast, acute diverticulitis refers to acute inflammation in the diverticula. Low dietary fibre intake is reported to increase the risk of diverticular disease. In the UK, the prevalence rises from approximately 5% of people in their 40s to almost 50% of those above the age of 80. It is estimated that 20% of patients with diverticulosis will develop symptoms at some point in their lifetime. Diverticular disease can be confirmed radiologically or endoscopically. Referral of patients with symptomatic diverticular disease to secondary care is not indicated unless: the symptoms affect their quality of life; the pain is not controlled by paracetamol; new symptoms develop which require further investigation; there are concerns about the possibility of an alternative diagnosis or patients develop red flag symptoms. Even in patients with established diverticulosis, a change in the clinical picture with development of red flag symptoms warrants urgent referral to rule out lower gastrointestinal malignancy. Patients with suspected uncomplicated acute diverticulitis should be assessed according to their level of pain and associated systemic features of sepsis. In those where pain is controlled and there are no signs of systemic sepsis or multiple comorbidities, the patient may be treated in primary care.

    There has been growing interest in the use of MRI in assessing Crohn's disease because of its lack of ionising radiation. Many MRI signs have been described in the literature, but their relative utility is unknown. The MRIs of the bowel performed at 1.5 Tesla were blindly reviewed on 26 patients with recent histology (surgery and/or colonoscopy and their associated reports) according to a dedicated pro forma. Each patient's bowel was divided into nine segments. Each segment was assessed as to the presence or absence of 15 MRI signs described in the literature: abnormal gadolinium enhancement (both subjective and objective), wall oedema, fat oedema, fat proliferation, nodal enlargement, free fluid, wall nodularity, serosal blurring, mural thickening >4 mm, stricture, multi-segmental disease, fistula, abscess and layered contrast enhancement. The results were compared against a histological gold standard with a six-point scale of disease severity. MRI correctly identified all 15 patients with at least established mucosal disease, and three of eight with only mild mucosal disease. Combining these results, a positive MRI correlated highly with at least early mucosal disease (positive predictive value 95%), while the presence of established mucosal disease was unlikely if MRI was negative (negative predictive value 100%). The MRI signs found to be the most sensitive for detecting active Crohn's disease were those related to the bowel wall, namely, wall thickening, nodularity, contrast enhancement and oedema. The most specific signs were the presence of multi-segmental disease, layered contrast enhancement and complications (fistula and abscess).

    The typical macroscopic features of Crohn's disease have been well described and are widely regarded as sufficient to diagnose the disease at laparotomy. We report six patients undergoing laparotomy for symptomatic Crohn's disease, shown radiologically, who were found to have macroscopically normal small bowel despite careful examination of the bowel by an experienced surgeon. In four cases resection was deferred, but all subsequently deteriorated and required further surgery. Minor abnormali...

    Vitamin D regulates intestinal epithelial and immune functions, and vitamin D receptor deficiency increases the severity of murine colitis. Bioavailable 25-hydroxyvitamin D (25(OH)D) is available to target tissues and may be a driver of immune function. The aim is to evaluate the relationship of bioavailable 25(OH)D to the clinical expression of treatment naive pediatric ulcerative colitis (UC). The PROTECT (Predicting Response to Standardized Pediatric Colitis Therapy) study enrolled children ≤17 years newly diagnosed with UC. Free and total 25(OH)D were directly measured and 25(OH)D fractions were compared with disease activity measures. Data were available on 388 subjects, mean age 12.7 years, 49% female, 84% with extensive/pancolitis. The median (IQR) total 25(OH)D concentration was 28.5 (23.9, 34.8) ng/mL, and 57% of subjects demonstrated insufficient vitamin D status (25(OH)D < 30 ng/mL). We found no evidence of association between total 25(OH)D and disease activity. Regression models adjusted for age, sex, race, and ethnicity demonstrated that an increase from 25th to 75th percentile for bioavailable and free 25(OH)D were associated with a mean (95th CI) decrease in the Pediatric Ulcerative Colitis Activity Index (PUCAI) of -8.7 (-13.7, -3.6) and -3.1 (-5.0, -1.2), respectively. No associations were detected between 25(OH)D fractions and fecal calprotectin or Mayo endoscopy score. Vitamin D insufficiency is highly prevalent in children with newly diagnosed UC. We found associations of free and bioavailable, but not total 25(OH)D, with PUCAI. Bioavailable vitamin D may contribute to UC pathophysiology and clinical activity.

    Recent technological improvements have increased the use of genetic testing in the clinic. This review serves to summarize the many practical benefits of genetic testing, discusses various methodologies that can be used clinically, and exemplifies ways in which genetics is propelling the field forward in nephrology. The advent of next-generation sequencing and microarray technologies has heralded an unprecedented number of discoveries in the field of nephrology, providing many opportunities for incorporating genomic diagnostics into clinical care. The use of genetic testing, particularly in pediatrics, can provide accurate diagnoses in puzzling cases, resolve misclassification of disease, and identify subsets of individuals with treatable conditions. Genetic testing may have broad benefits for patients and their families. Knowing the precise molecular etiology of disease can help clinicians determine the exact therapeutic course, and counsel patients and their families about prognosis. Genetic discoveries can also improve the classification of kidney disease and identify new targets for therapy.

    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.

    An automated and autonomous diagnostic apparatus that is capable of dispensing collection vials and collections kits to users interesting in collecting a biological sample and submitting their collected sample contained within a collection vial into the apparatus for automated diagnostic services. The user communicates with the apparatus through a touch-screen monitor. A user is able to enter personnel information into the apparatus including medical history, insurance information, co-payment, and answer a series of questions regarding their illness, which is used to determine the assay most likely to yield a positive result. Remotely-located physicians can communicate with users of the apparatus using video tele-medicine and request specific assays to be performed. The apparatus archives submitted samples for additional testing. Users may receive their assay results electronically. Users may allow the uploading of their diagnoses into a central databank for disease surveillance purposes.

    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

    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.

     Globalization and emigration impact on the spectrum of diseases challenging health care systems. 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.

    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.

    Estrogen exposure has been associated with the occurrence of Parkinson's disease (PD), as well as many other disorders, and yet the mechanisms underlying these relations are often unknown. 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....

    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.

    While detailed history, physical examination, and laboratory tests are of great importance when examining a patient with diverticular disease, they are not sufficient to diagnose (or stratify) diverticulitis without cross-sectional imaging (ultrasonography (US), computed tomography (CT)). Qualified US has diagnostic value equipotent to qualified CT, follows relevant legislation for radiation exposure protection, and is frequently effectual for diagnosis. Furthermore, its unsurpassed resolution allows detailed investigation down to the histological level. Subsequently, US is considered the first choice of imaging in diverticular disease. Vice versa, CT has definite indications in unclear/discrepant situations or insufficient US performance. Endoscopy is not required for the diagnosis of diverticulitis and shall not be performed in the acute attack. Colonoscopy, however, is warranted after healing of acute diverticulitis, prior to elective surgery, and in atypical cases suggesting other diagnoses. Perforation/abscess must be excluded before colonoscopy. Reliable diagnosis is fundamental for surgical, interventional, and conservative treatment of the different presentations of diverticular disease. Not only complications of acute diverticulitis but also a number of differential diagnoses must be considered. For an adequate surgical strategy, correct stratification of complications is mandatory. Subsequently, in the light of currently validated diagnostic techniques, the consensus conference of the German Societies of Gastroenterology (DGVS) and of Visceral Surgery (DGAV) has passed a new classification of diverticulitis displaying the different facets of diverticular disease. This classification addresses different types (not stages) of the condition, and includes symptomatic diverticular disease (SUDD), largely resembling irritable bowel syndrome, as well as diverticular bleeding.

    2000-01-01

    Objective: To evaluate the value of CT for diagnosing benign diseases of breast. Methods: The breast CT scan and mammography were performed on 44 patients (78 focus). The accuracy of determining the position and nature of breast diseases was compared between the two mentioned diagnostic methods. All cases were confirmed as breast benign disease by pathology. Results: CT played a remarkable role in the diagnosis of breast fibroadenoma and cyst, and is superior to mammography in demonstrating deep breast lesion, multiple-focus and multiple-patterns benign diseases of breast. The accuracy of CT and mammography in determining the position and nature of benign diseases of breast were 85% and 54% (x 2 = 12.58, P 2 = 8.29, P < 0.01) respectively. Conclusion: CT has a higher accuracy than mammography in determining the position and nature of breast benign disease

    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.

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.

    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.

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

    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.

  12. Are current chronic fatigue syndrome criteria diagnosing different disease phenotypes?

    Full Text Available Chronic fatigue syndrome (CFS is characterised by a constellation of symptoms diagnosed with a number of different polythetic criteria. Heterogeneity across these diagnostic criteria is likely to be confounding research into the as-yet-unknown pathophysiology underlying this stigmatised and debilitating condition and may diagnose a disease spectrum with significant implications for clinical management. No studies to date have objectively investigated this possibility using a validated measure of CFS symptoms-the DePaul Symptom Questionnaire (DSQ.To examine whether current CFS diagnostic criteria are identifying different disease phenotypes using the DSQ.Case control study.Clinical Research Facility of the Royal Victoria Infirmary, Newcastle upon Tyne, UK.49 CFS subjects and ten matched, sedentary community controls, excluded for co-morbid depression.Self-reported autonomic and cognitive features were assessed with the Composite Autonomic Symptom Score (COMPASS and Cognitive Failures Questionnaire (COGFAIL respectively. Objective autonomic cardiovascular parameters were examined using the Task Force® Monitor and a battery of neuropsychological tests administered for objective cognitive assessment.Self-reported autonomic and cognitive symptoms were significantly greater in CFS subjects compared to controls. There were no statistically significant differences in objective autonomic measures between CFS and controls. There were clinically significant differences between DSQ subgroups on objective autonomic testing. Visuospatial memory, verbal memory and psychomotor speed were significantly different between DSQ subgroups.The finding of no significant differences in objective autonomic testing between CFS and control subjects may reflect the inclusion of sedentary controls or exclusion for co-morbid depression. Consistent exclusion criteria would enable better delineation of these two conditions and their presenting symptoms. Findings across CFS

    Full Text Available Buerger's disease or thromboangiitis obliterans (TAO seems to be common in IR Iran, The present study aimed to evaluate an Iranian population with Buerger's disease in order to suggest a diagnostic criterion for Buerger's disease based on the most frequent findings and to compare it with Papa diagnostic criteria. In a cross-sectional study, all patients with resting limb pain, limb ischemic ulcers, intermittent claudication and limb ischemia who referred to the Vascular Clinic of Sina Hospital during 2009-2011 were evaluated. The patients were allocated to Buerger's and non-Buerger's groups; Evaluating 122 patients (61 in each group, according to the model each clinical manifestations and risk factors in the patients with Buerger's disease obtained a score. Absent pulsation, abnormal distal Doppler sonography and ischemic ulcer were respectively present in 58 (95.1%, 58 (95.1% and 49 (80.3% individuals with Buerger's disease. Multivariate linear regression analysis and multivariate logistic regression analysis were used for modeling. Considering the model finding findings, diagnostic criteria including age, sex, smoking, Raynaud's phenomenon, abnormal proximal Doppler, diabetes mellitus and hyperlipidemia were suggested (R2=0.582; the sensitivity and specificity of the criteria was respectively 95.1% and 78.7%. Compared with Papa criteria, Kappa coefficient was measured at 0.66 with a P-value<0.001. It seems that the recommended criteria have an acceptable accuracy in diagnosing Buerger's disease, especially in the Iranian population; however, it is necessary to conduct more studies with larger sample sizes to evaluate the criteria, especially in other populations.

    Data are lacking on the spectrum of sexually transmitted diseases (STDs) diagnosed in returning travelers. All consecutive travelers consulting our tropical unit between November 1, 2002 and October 31, 2003 were included if they presented within 1 month after their return from the tropics, with mucocutaneous signs suggesting STDs. Forty-nine patients (12 women and 37 men; median age 36.4 y, 35 heterosexuals) were included. Four patients had traveled with their usual sexual partner and 45 patients had casual sex while abroad (31 with locals and 14 with other tourists). The main diagnoses were gonococcal urethritis (n = 18), herpes simplex virus 2 infection (n = 12), urethritis of undetermined origin (n = 9), Chlamydia trachomatis infection (n = 4), primary syphilis (n = 4), and primary human immunodeficiency virus infection (n = 2). These results illustrate the broad spectrum of STDs contracted by travelers to the tropics. They suggest the need to also inform travelers of the risks of STD and to promote the use of condoms in case of casual sex while abroad.

    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.

  17. Biomarkers for diagnosing and staging of Fabry disease.

    Fabry disease is a X-linked lysosomal storage disorder caused by deficient activity of α -galactosidase A which leads to progressive intracellular accumulation of globotriaosylceramide in tissues and organs including heart, kidney, vascular endothelium, the nervous system, the eyes and the skin. Cardiac involvement is common, leads to fatal complications and is mainly responsible for reduced life expectancy in Fabry disease. The exact staging of disease progression and timely initiation of treatment is essential in Fabry disease. Therefore it is essential to use the possibilities of specific biomarkers for early detection of organ involvement or early diagnosis. By the use of Pubmed all relevant papers for biomarkers in Fabry disease were screened. The quality of retrieved papers was appraised using standard tools. Finally 56 peer reviewed paper were included. In the past biomarkers for Fabry disease biomarkers did not have clinical relevance. Nowadays, a lot of research is focusing on identification of new biomarkers and their clinical relevance. Only two biomarkers reached clinical applicability. Lyso-GB3 for identification of atypical FD variants and hsTNT for identification of cardiac involvement, which should indicate further diagnostics. Treatment response to ERT can be monitored by lyso-GB3 but data for long-time outcome are missing. A lot of GB3-related analogues are identified in urine and plasma, some of which might play an important role for managing Fabry disease in future. In conclusion, we suggest to measure lyso-GB3 and hsTNT at least once a year. The routinely measurement of these two biomarkers will help now for the staging of every individual patient and in addition, will help for a better general understanding of Fabry disease .

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

    Full Text Available OBJECTIVES: High-throughput mass spectrometry methods have been developed to screen newborns for lysosomal storage disorders, allowing the implementation of newborn screening pilot studies in North America and Europe. It is currently feasible to diagnose Pompe, Fabry, Gaucher, Krabbe, and Niemann-Pick A/B diseases, as well as mucopolysaccharidosis I, by tandem mass spectrometry in dried blood spots, which offers considerable technical advantages compared with standard methodologies. We aimed to investigate whether the mass spectrometry methodology for lysosomal storage disease screening, originally developed for newborns, can also discriminate between affected patients and controls of various ages. METHODS: A total of 205 control individuals were grouped according to age and subjected to mass spectrometry quantification of lysosomal α-glucosidase, β-glucocerebrosidase, α-galactosidase, acid sphingomyelinase, galactocerebrosidase, and α−L-iduronidase activities. Additionally, 13 affected patients were analyzed. RESULTS: The median activities for each enzyme and each age group were determined. Enzyme activities were significantly lower in individuals aged older than 18 years compared with those in newborns. Affected patients presented enzymatic activities corresponding to less than 20% of the age-matched controls. CONCLUSIONS: Our data indicate that the mass spectrometry methodology can be used for the screening of lysosomal storage diseases in non-newborn patients. However, for some diseases, such as Fabry and mucopolysaccharidosis I, a combination of biochemical and clinical data may be necessary to achieve accurate diagnoses.

    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.

    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

    Epilepsy is a major feature of Menkes disease, an X-linked recessive infantile neurodegenerative disorder caused by mutations in ATP7A, which produces a copper-transporting ATPase. Three prior surveys indicated clinical seizures and electroencephalographic (EEG) abnormalities in a combined 27 of 29 (93%) symptomatic Menkes disease patients diagnosed at 2 months of age or older. To assess the influence of earlier, presymptomatic diagnosis and treatment on seizure semiology and brain electrical activity, we evaluated 71 EEGs in 24 Menkes disease patients who were diagnosed and treated with copper injections in early infancy (≤6 weeks of age), and whose ATP7A mutations we determined. Clinical seizures were observed in only 12.5% (3/24) of these patients, although 46% (11/24) had at least one abnormal EEG tracing, including 50% of patients with large deletions in ATP7A, 50% of those with small deletions, 60% of those with nonsense mutations, and 57% of those with canonical splice junction mutations. In contrast, five patients with mutations shown to retain partial function, either via some correct RNA splicing or residual copper transport capacity, had neither clinical seizures nor EEG abnormalities. Our findings suggest that early diagnosis and treatment improve brain electrical activity and decrease seizure occurrence in classical Menkes disease irrespective of the precise molecular defect. Subjects with ATP7A mutations that retain some function seem particularly well protected by early intervention against the possibility of epilepsy. PMID:20652413

    Walton, Shelley F.; Currie, Bart J.

    2007-01-01

    Scabies is a worldwide disease and a major public health problem in many developing countries, related primarily to poverty and overcrowding. In remote Aboriginal communities in northern Australia, prevalences of up to 50% among children have been described, despite the availability of effective chemotherapy. Sarcoptic mange is also an important veterinary disease engendering significant morbidity and mortality in wild, domestic, and farmed animals. Scabies is caused by the ectoparasitic mite Sarcoptes scabiei burrowing into the host epidermis. Clinical symptoms include intensely itchy lesions that often are a precursor to secondary bacterial pyoderma, septicemia, and, in humans, poststreptococcal glomerulonephritis. Although diagnosed scabies cases can be successfully treated, the rash of the primary infestation takes 4 to 6 weeks to develop, and thus, transmission to others often occurs prior to therapy. In humans, the symptoms of scabies infestations can mimic other dermatological skin diseases, and traditional tests to diagnose scabies are less than 50% accurate. To aid early identification of disease and thus treatment, a simple, cheap, sensitive, and specific test for routine diagnosis of active scabies is essential. Recent developments leading to the expression and purification of S. scabiei recombinant antigens have identified a number of molecules with diagnostic potential, and current studies include the investigation and assessment of the accuracy of these recombinant proteins in identifying antibodies in individuals with active scabies and in differentiating those with past exposure. Early identification of disease will enable selective treatment of those affected, reduce transmission and the requirement for mass treatment, limit the potential for escalating mite resistance, and provide another means of controlling scabies in populations in areas of endemicity.

    This study examines the clinical decision support systems in healthcare, in particular about the prevention, diagnosis and treatment of respiratory diseases, such as Asthma and chronic obstructive pulmonary disease. The empirical pulmonology study of a representative sample (n = 132) attempts to identify the major factors that contribute to the diagnosis of these diseases. Machine learning results show that in chronic obstructive pulmonary disease's case, Random Forest classifier outperforms other techniques with 97.7 per cent precision, while the most prominent attributes for diagnosis are smoking, forced expiratory volume 1, age and forced vital capacity. In asthma's case, the best precision, 80.3 per cent, is achieved again with the Random Forest classifier, while the most prominent attribute is MEF2575.

    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.

  16. Radioisotope heart examination during exercise to diagnose ischemic heart disease

    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.) [German] Klinisch imponieren Kleinhirnsyndrome durch Ataxie, Dysarthrie, Dysmetrie, Intentionstremor und Augenbewegungsstoerungen.

    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.

    Full Text Available Pompe disease (PD, or glycogen storage disease type II, is a rare autosomal recessive lysosomal disease caused by glycogen storage in the myocardium, skeletal muscles, and liver. PD, as an orphan disease with a very low prevalence rate, shows a marked clinical polymorphism, making its early diagnosis difficult. Yet, the efficiency of pathogenetic treatment for the disease is closely related to the time of its diagnosis, what is particularly relevant for infantile-onset PD. We present our clinical case of a sick baby with this condition diagnosed during life. The clinical diagnostic criteria were the neonatal form of rapidly progressive hypertrophic cardiomyopathy, macroglossia, floppy baby syndrome. Enzymatic diagnosis in the dried blood spots revealed the low activity of the enzyme α-glucosidase. Direct GAA gene sequencing identified heterozygous mutations in the infant’s parents: с.1799 G>A (p.Arg600His in his father and c.1951_1952 delGGinsT in his mother, which allows its early prenatal diagnosis at 9-11 weeks of gestation.

    Lyme disease is a vector-borne infection, primarily transmitted by Ixodes ticks, and caused by Borrelia burgdorferi. It has a wide distribution in the northern hemisphere. In Korea, however, only one human case has been reported, although B. burgdorferi was isolated from the vector tick I. persulcatus in the region. A 60-year-old male and a 45-year-old female developed the clinical sign of erythema migrans. Each patients were bitten by a tick four weeks and five weeks, respectively, before entering the hospital. On serologic examination, significantly increased IgM and IgG antibody titers to B. burgdorferi were observed in consecutive tests performed at an interval of two weeks. They responded well to treatment with tetracycline. PMID:10102530

    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.

    Full Text Available Background Regular physical activity can be effective not only in preventing diabetes and managing its complications but also be effective in minimizing the risk of developing other chronic diseases among diabetics. The overall aim of study was to determine probable causes of change in physical activity so as to generate evidences for future interventions and to identify psychosocial covariates of self reported physical activity in recently diagnosed Type 2 diabetes cases. Methods Participants n=478 (239 intervention arm and 239 control arm of an observational cohort were randomized into the ADDITION Plus trial and were recruited from 36 practices in East Anglia region. Participants were people recently diagnosed with diabetes (screen detected and clinically diagnosed within the preceding 3 years were individually randomized and were between the age group of 40-69 years, (mean age 59.2 years. The self reported data regarding physical activity was measured at baseline and one year were used. Demographic and psychosocial (treatment control, consequences, anxiety covariates were assessed at the baseline. Linear univariate and multivariable linear regression analysis was used to quantify the associations between demographic and psychosocial correlates. Results: With regard to the psychosocial correlates(except for participants’ perceptions about the consequences of diabetes, no significant associations with physical activity were found. Treatment control and anxiety failed to predict physical activity. Conclusion The result suggests to further investigate the change in physical activity by including other variables related to demography, other psycho-social and environment influences. Based on the available literature, it is suggested that other factors were found consistently associated with physical activity such as self efficacy, attitude, sensation seeking, family-friend social support, goal orientation, motivation could be studied.

    Primary immunodeficiency diseases (PID) are a rare group of disorders with a wide array of clinical presentations. The absence of validated methods to identify these diseases in electronic databases has limited understanding of their epidemiology and the impact of drug therapies on outcomes. We measured the positive predictive values (PPVs) of ICD-9 diagnoses for identifying PID within US Medicaid. We identified Medicaid patients from California, Florida, New York, Ohio, and Pennsylvania with PID ICD-9 diagnoses (common variable immunodeficiency [279.06], X-linked agammaglobulinemia [279.04], hyper-immunoglobulin M syndrome [279.05], Wiskott Aldrich Syndrome [279.12]) recorded at least twice from 1999 to 2007. Outpatient records were reviewed by a clinical immunologist to adjudicate diagnoses. PPVs with 95% confidence intervals (CIs) for confirmed outcomes were determined for individual ICD-9 diagnoses and combinations of diagnoses and Current Procedural Terminology codes for a quantitative immunoglobulin test (82784) or immunoglobulin infusion (96365). Among 83 patients with PID ICD-9 diagnoses, 16 were adjudicated as having the condition (PPV, 19.3%; 95% CI, 11.4-29.4%). Individual ICD-9 diagnoses had low PPVs (range, 16.7-33.3%). Requiring procedural codes for quantitative immunoglobulins or intravenous immunoglobulin did not increase PPVs of these diagnoses (range, 11.1-41.7%). An X-linked agammaglobulinemia diagnosis plus intravenous immunoglobulin had the highest PPV among the algorithms evaluated (PPV, 41.7%; 95% CI, 15.1-72.3%). Algorithms comprising PID ICD-9 diagnoses and procedures for quantitative immunoglobulin tests and immunoglobulin infusion had low PPVs for adjudicated diagnoses in Medicaid. Alternative data sources should be evaluated to study the epidemiology of these diseases.

    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.

    2018-02-27

    Hospital revenues generated by diagnosis-related groups (DRGs) are in part dependent on the coding of secondary diagnoses. Therefore, more and more hospitals trust specialized coders with this task, thereby relieving doctors from time-consuming administrative burdens and establishing a highly professionalized coding environment. However, it is vastly unknown if the revenues generated by the coders do indeed exceed their incurred costs. Coding data from the departments of dermatology, ophthalmology, and infectious diseases from Rostock University Hospital from 2007-2016 were analyzed for the effects of secondary diagnoses on the resulting DRG, i. e., hospital charges. Ophthalmological case were highly resistant to the addition of secondary diagnoses. In contrast, adding secondary diagnoses to cases from infectious diseases resulted in 15% higher revenues. Although dermatological and infectious cases share the same sensitivity to secondary diagnoses, higher revenues could only rarely be realized in dermatology, probably owing to a younger, less multimorbid patient population. Except for ophthalmology, trusting specialized coders with clinical coding generates additional revenues through the coding of secondary diagnoses which exceed the costs for employing these coders.

    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

    2016-12-01

    In contrast to the rapid development of the horse husbandry in China, the ability of horse veterinarians to diagnose diseases has not been improved and only a few domain experts have considerable expertise. At present, many expert systems have been developed for diseases diagnosis, but few for horse diseases diagnosis have been studied in depth. This paper presents the design and development of a computer-aided expert system for diagnosing horse diseases. We suggest an approach for diagnosis of horse diseases based on the analysis of diagnostic characteristics and the experiential knowledge of domain experts. It is based on using evidence-weighted uncertainty reasoning theory, which is a combination of evidence theory and an uncertainty pass algorithm of confidence factors. It enables drawing of inferences with atypical clinical signs and the uncertainty of the user's subjective understanding. It reduces the influence of subjective factors on diagnostic accuracy. The system utilizes a user friendly interface for users and requests a confidence factor from users when feedback is given to the system. Horse-Expert combines the confidence factors with weight factors assigned to clinical signs by experts during the knowledge acquisition process to make diagnostic conclusions. The system can diagnose 91 common horse diseases, and provides suggestions for appropriate treatment options. In addition, users can check the medical record through statistical charts. The system has been tested in seven demonstration areas of Xinjiang province in northwestern China. By constantly maintaining and updating the knowledge base, the system has potential application in veterinary practice.

    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.

    To examine the validity of case definitions for systemic autoimmune rheumatic diseases [SARD; systemic lupus erythematosus (SLE), systemic sclerosis (SSc), myositis, Sjögren's syndrome, vasculitis, and polymyalgia rheumatica] based on administrative data, compared to rheumatology records. A list of rheumatic disease diagnoses was generated from population-based administrative billing and hospitalization databases. Subjects who had been seen by an arthritis center rheumatologist were identified, and the medical records reviewed. We found that 844 Nova Scotia residents had a diagnosis of one of the rheumatic diseases of interest, based on administrative data, and had had ≥ 1 rheumatology assessment at a provincial arthritis center. Charts were available on 824 subjects, some of whom had been identified in the administrative database with > 1 diagnosis. Thus a total of 1136 diagnoses were available for verification against clinical records. Of the 824 subjects, 680 (83%) had their administrative database diagnoses confirmed on chart review. The majority of subjects who were "false-positive" for a given rheumatic disease on administrative data had a true diagnosis of a similar rheumatic disease. Most sensitivity estimates for specific administrative data-based case definitions were > 90%, although for SSc, the sensitivity was 80.5%. The specificity estimates were also > 90%, except for SLE, where the specificity was 72.5%. Although health administrative data may be a valid resource, there are potential problems regarding the specificity and sensitivity of case definitions, which should be kept in mind for future studies.

    2012-02-01

    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.

    1982-01-01

    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.

    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.

  10. Limited role of HLA DQ2/8 genotyping in diagnosing coeliac disease.

    2017-02-01

    The European guidelines for diagnosing coeliac disease in children were revised in 2012. These recommend that in symptomatic children, a diagnosis of coeliac disease can be made without small-bowel biopsies provided their anti-tissue transglutaminase (anti-tTG) titre is >10 times of upper-limit-of-normal (>10×ULN) and anti-endomysial antibody is positive. In order to firm up the diagnosis in these children with very high anti-tTG titre, HLA-DQ2/DQ8 should be checked and be positive. Approximately 25-40% of white Caucasian population has HLA-DQ2/DQ8 haplotype. However, only 0.1-1% of the population will develop coeliac disease. Therefore, HLA-DQ2/DQ8 testing must not be done to 'screen' or 'diagnose' children with coeliac disease. Its use by paediatricians should be limited to children with anti-tTG>10×ULN, where the diagnosis of coeliac disease is being made on serology alone. A review of case referrals made to a tertiary paediatric gastroenterology centre in Southwest England demonstrated that HLA-DQ2/DQ8 testing is being requested inappropriately both in primary and secondary care suggesting a poor understanding of its role in diagnosis of coeliac disease. This article aims to clarify the role of HLA-DQ2/DQ8 testing for clinicians working in non-specialist settings.

    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.

  12. Who Can Diagnose Parkinson's Disease First? Role of Pre-motor Symptoms.

    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.

    2012-01-01

    When a bulging appendiceal orifice is observed during surveillance colonoscopy, the possibility of appendiceal mucocele must be considered. Appendiceal mucocele is a rare group of lesions characterized by mucinous distension of the appendiceal lumen with the dangerous potential to rupture, resulting in the development of pseudomyxoma peritonei. Early recognition and diagnosis of appendiceal mucocele can prevent the dreaded complication of pseudomyxoma peritonei but it requires a high index of suspicion. Patients with inflammatory bowel disease are at increased risk for colorectal neoplasm but neoplasm of the appendix is infrequently reported. We report two of the first cases of appendiceal mucoceles diagnosed in patients with inflammatory bowel disease using endoscopic ultrasound.

    To determine the incidence of synchronous upper-tract transitional cell carcinomas (TCCs) in patients with newly diagnosed bladder cancer and to evaluate the need for performing intravenous urography (IVU) in these patients. Imaging data on 330 consecutive patients who were diagnosed with TCC of the bladder over a 2-year period were retrospectively reviewed. Only 233 out of the 330 patients had IVU at presentation. The IVU results were recorded as normal, abnormal, or equivocal. The follow-up radiological or urological investigations in the patients who had an equivocal IVU were reviewed. Clinical follow-up data on all 330 patients were also recorded. Only 233 out of the 330 patients had an IVU at presentation. Four of these (1.7%) patients were found to have synchronous upper-tract tumours. Twenty-two patients were reported to have equivocal findings on IVU. Nine of these patients had follow-up imaging [computed tomography (CT)=5, IVU=4], which were reported as normal. Retrograde urography was performed in two patients, which was normal. The remaining 11 patients did not have any evaluation of the upper tracts despite the equivocal findings on IVU, but routine clinical follow-up did not reveal any significant disease. Three patients with high-risk superficial disease developed upper-tract tumours that were detected on follow-up. IVU for diagnosing synchronous upper-tract tumours in patients with newly diagnosed bladder carcinoma can be restricted to patients with high-risk superficial disease.

  17. Exploring the genetic counselor's role in facilitating meaning-making: rare disease diagnoses.

    2015-04-01

    The main goal of the constructivist meaning-making framework is to encourage grief adaptation through the search for meaning in loss. Strategies to help patients construct meaning from their experiences may lead to positive adaptation. This strategy has been used in contemporary grief counseling, but it may also be beneficial in the genetic counseling scenario. The diagnosis of a rare genetic disorder often has considerable psychosocial impact as patients and families describe feelings of isolation and hopelessness. Negative experiences with healthcare providers often reinforce these feelings. Genetic counselors continue to provide education and psychosocial support to patients and families with rare genetic disorders, and meaning-making strategies may provide a framework for which to help patients and families adapt to these challenging diagnoses. In this paper I explore the background of meaning-making counseling strategy and describe an experience in which it was used for counseling a family with a child with Mowat-Wilson syndrome. I show how a meaning-making framework can help families explore and construct meaning from their experiences and encourage positive adaptation. I also address the possible limitations of this strategy and the need to share additional experiences with this counseling framework. Meaning-making can be another tool for genetic counselors to help guide families in their grief and adaptation to rare disease diagnoses. I also describe qualities and aspects of counseling through the lens of meaning-making and stress the importance of addressing psychosocial dimensions of rare disease diagnoses.

    2003-05-01

    The correlation between periodontal disease and osteoporosis was evaluated by comparing age, panoramic radiographic and clinical parameters of periodontal disease. Diagnosis of osteoporosis in periodontal diseased patients was evaluated by panoramic radiographic parameters (mandibular cortical width:MCW). Subjects which had more than 20 teeth and examined by panoramic radiography were untreated adults with periodontal disease who were free of other systemic disease. The following parameters were examined on panoramic X-ray film:alveolar bone loss (ABL), mandibular bone mass with the use of mandibular cortical width (MCW). ABL was significantly higher and MCW significantly lower in the postmenopausal group (>6 years after menopause). The number of teeth was significantly lower and CAL significantly higher in the postmenopausal group (>11 years after menopause). Age and ABL correlated positively in men and women. Years after menopause and ABL and MCW and CAL in the postmenopausal group were correlated positively. Women whose MCW was less than mean - 2 SD should be diagnosed with osteoporosis. Our results demonstrated that periodontal disease correlates with osteoporosis, and MCW could be useful in detecting of osteoporosis in women with periodontal disease.

  20. ADAR2 editing activity in newly diagnosed versus relapsed pediatric high-grade astrocytomas

    High-grade (WHO grade III and IV) astrocytomas are aggressive malignant brain tumors affecting humans with a high risk of recurrence in both children and adults. To date, limited information is available on the genetic and molecular alterations important in the onset and progression of pediatric high-grade astrocytomas and, even less, on the prognostic factors that influence long-term outcome in children with recurrence. A-to-I RNA editing is an essential post-transcriptional mechanism that can alter the nucleotide sequence of several RNAs and is mediated by the ADAR enzymes. ADAR2 editing activity is particularly important in mammalian brain and is impaired in both adult and pediatric high-grade astrocytomas. Moreover, we have recently shown that the recovered ADAR2 activity in high-grade astrocytomas inhibits in vivo tumor growth. The aim of the present study is to investigate whether changes may occur in ADAR2-mediated RNA editing profiles of relapsed high-grade astrocytomas compared to their respective specimens collected at diagnosis, in four pediatric patients. Total RNAs extracted from all tumor samples and controls were tested for RNA editing levels (by direct sequencing on cDNA pools) and for ADAR2 mRNA expression (by qRT-PCR). A significant loss of ADAR2-editing activity was observed in the newly diagnosed and recurrent astrocytomas in comparison to normal brain. Surprisingly, we found a substantial rescue of ADAR2 editing activity in the relapsed tumor of the only patient showing prolonged survival. High-grade astrocytomas display a generalized loss of ADAR2-mediated RNA editing at both diagnosis and relapse. However, a peculiar Case, in complete remission of disease, displayed a total rescue of RNA editing at relapse, intriguingly suggesting ADAR2 activity/expression as a possible marker for long-term survival of patients with high-grade astrocytomas

    Anemia and low hemoglobin have been identified to increase Parkinson's disease (PD) risk. This population-based cohort study investigated PD risk in newly diagnosed anemic patients by using data from the Taiwan National Health Insurance Research Database. All newly diagnosed anemic patients (n = 86,334) without a history of stroke, neurodegenerative diseases, traumatic brain injury, major operations, or blood loss diseases were enrolled. A cohort of nonanemic controls, 1:1 matched with anemic patients on the basis of the demographics and pre-existing medical conditions, was also included. Competing risk analysis was used to evaluate PD risk in anemic patients compared with that in their matched controls. The adjusted hazard ratio (aHR) of PD risk in the anemic patients was 1.36 (95% confidence interval [CI]: 1.22-1.52, p anemia (IDA) patients tended to exhibit a higher PD risk (aHR: 1.49; 95% CI: 1.24-1.79, p anemia increases PD risk.

    2017-01-01

    Of 57 individuals diagnosed with Alzheimer's disease (AD) in a phase III study, 13 (23%) had amyloid-β (Aβ) levels on postmortem histopathology that did not explain the dementia. Based on postmortem histopathology, a wide range of different non-AD conditions was identified, including frontotemporal dementia, hippocampal sclerosis, and dementia with Lewy bodies. Of the histopathologically Aβ negative scored cases ante-mortem Florbetaben PET scans were classified as negative for Aβ in 11 patients based on visual analysis and in all 12 quantifiable cases based on composite standardized uptake value ratios. Thus, florbetaben PET can assist physicians in the differential diagnosis of neurodegenerative disorders by reliably excluding Aβ pathology.

    2016-11-01

    Thyroid hormones are essential developmental factors, and Graves' disease (GD) may severely complicate a pregnancy. This review describes how pregnancy changes the risk of developing GD, how early pregnancy by several mechanisms leads to considerable changes in the results of the thyroid function tests used to diagnose hyperthyroidism, and how these changes may complicate the diagnosing of GD. Standard therapy of GD in pregnancy is anti-thyroid drugs. However, new studies have shown considerable risk of birth defects if these drugs are used in specific weeks of early pregnancy, and this should be taken into consideration when planning therapy and control of women who may in the future become pregnant. Early pregnancy is a period of major focus in GD, where pregnancy should be diagnosed as soon as possible, and where important and instant change in therapy may be warranted. Such change may be an immediate stop of anti-thyroid drug therapy in patients with a low risk of rapid relapse of hyperthyroidism, or it may be an immediate shift from methimazole/carbimazole (with risk of severe birth defects) to propylthiouracil (with less risk), or maybe to other types of therapy where no risk of birth defects have been observed. In the second half of pregnancy, an important concern is that not only the mother with GD but also her foetus should have normal thyroid function. © 2016 European Society of Endocrinology.

    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.

    Current information is scarce regarding comorbid conditions, treatment, survival, institutionalization, and health care utilization for Alzheimer's disease (AD) patients. Compare all-cause mortality, rate of institutionalization, and economic burden between treated and untreated newly-diagnosed AD patients. Patients aged 65-100 years with ≥1 primary or ≥2 secondary AD diagnoses (ICD-9-CM:331.0] with continuous medical and pharmacy benefits for ≥12 months pre-index and ≥6 months post-index date (first AD diagnosis date) were identified from Medicare fee-for-service claims 01JAN2011-30JUN2014. Patients with AD treatment claims or AD/AD-related dementia diagnosis during the pre-index period were excluded. Patients were assigned to treated and untreated cohorts based on AD treatment received post-index date. Total 8,995 newly-diagnosed AD patients were identified; 4,037 (44.8%) were assigned to the treated cohort. Time-to-death and institutionalization were assessed using Cox regression. To compare health care costs and utilizations, 1 : 1 propensity score matching (PSM) was used. Untreated patients were older (83.85 versus 81.44 years; p institutionalization (HR = 0.801; p = 0.0003). After PSM, treated AD patients were less likely to have hospice visits (3.25% versus 9.45%; p institutionalization, and sometimes fewer resource utilizations, suggesting that treatment and improved care management could be beneficial for newly-diagnosed AD patients from economic and clinical perspectives.

    Full Text Available Abstract Background Rupture of the spleen in the absence of trauma or previously diagnosed disease is largely ignored in the emergency literature and is often not documented as such in journals from other fields. We have conducted a systematic review of the literature to highlight the surprisingly frequent occurrence of this phenomenon and to document the diversity of diseases that can present in this fashion. Methods Systematic review of English and French language publications catalogued in Pubmed, Embase and CINAHL between 1950 and 2011. Results We found 613 cases of splenic rupture meeting the criteria above, 327 of which occurred as the presenting complaint of an underlying disease and 112 of which occurred following a medical procedure. Rupture appeared to occur spontaneously in histologically normal (but not necessarily normal size spleens in 35 cases and after minor trauma in 23 cases. Medications were implicated in 47 cases, a splenic or adjacent anatomical abnormality in 31 cases and pregnancy or its complications in 38 cases. The most common associated diseases were infectious (n = 143, haematologic (n = 84 and non-haematologic neoplasms (n = 48. Amyloidosis (n = 24, internal trauma such as cough or vomiting (n = 17 and rheumatologic diseases (n = 10 are less frequently reported. Colonoscopy (n = 87 was the procedure reported most frequently as a cause of rupture. The anatomic abnormalities associated with rupture include splenic cysts (n = 6, infarction (n = 6 and hamartomata (n = 5. Medications associated with rupture include anticoagulants (n = 21, thrombolytics (n = 13 and recombinant G-CSF (n = 10. Other causes or associations reported very infrequently include other endoscopy, pulmonary, cardiac or abdominal surgery, hysterectomy, peliosis, empyema, remote pancreato-renal transplant, thrombosed splenic vein, hemangiomata, pancreatic pseudocysts, splenic artery aneurysm

    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.

    In our recent paper, we study web search as an aid in the process of diagnosing rare diseases. To answer the question of how well Google Search and PubMed perform, we created an evaluation framework with 56 diagnostic cases and made our own specialized search engine, FindZebra (findzebra.com). FindZebra uses a set of publicly available curated sources on rare diseases and an open-source information retrieval system, Indri. Our evaluation and the feedback received after the publication of our paper both show that FindZebra outperforms Google Search and PubMed. In this paper, we summarize the original findings and the response to FindZebra, discuss why Google Search is not designed for specialized tasks and outline some of the current trends in using web resources and social media for medical diagnosis.

    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.

    Anxiety and mild cognitive impairment (MCI) are prevalent non-motor manifestations of Parkinson's disease (PD). While few studies have demonstrated a possible link between cognitive dysfunction and anxiety in PD, to our knowledge, no studies have directly examined the association between them. This study investigated the association between anxiety and cognitive deficits in newly diagnosed PD patients. Patients with newly diagnosed PD (N = 185) were recruited from community and outpatient clinics. Anxiety was assessed using the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) clinician rated anxiety item, which has previously been validated against a standardized criteria for the diagnosis of anxiety disorders in PD. Participants scoring ≥2 were classified as anxious. A threshold of 1 SD below normative values (obtained from controls) was used to define cognitive impairment. Impairments in specific cognitive domains were identified as being >1 SD below controls in ≥1 test per domain. After controlling for age, education and motor severity, patients with anxiety were three times more likely to have cognitive impairment compared to those without anxiety (OR = 3.0, 95% CI = 1.2-7.3, p impairment due to impairment in the memory domain compared with PD without anxiety (OR = 2.3, 95% CI = 1.0-5.1, p impairment (specifically memory impairment). Examining the neural basis of this association warrants future research in this developing field. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    A method for preparing amniotic fluid cell culture has been developed. The optimal conditions for the culture involved the incubation period averaging 17.9 days. Normal activity values were obtained for 8 glycosidases whose deficiency is responsible for the development of hereditary accumulation diseases. The data obtained allow a prenatal diagnosis of glycolipidoses (Tay-Sachs, Fabrys, Gaucher's diseases, etc.). The evidence on prenatal diagnosis of Tay-Sach's disease is presented.

    Objective To analyze the spectrum of prenatally diagnosed congenital heart disease in a Korean population with 22q11.2 deletion syndrome, and to provide guidelines for screening 22q11.2 deletion prenatally. Methods This retrospective study evaluated 1,137 consecutive fetuses that had prenatal genetic testing for 22q11.2 deletion because of suspected congenital heart disease between September 2002 and December 2012, at Asan Medical Center, Seoul, Korea. Results Main cardiovascular diseases in the 53 fetuses with confirmed 22q11.2 deletions were tetralogy of Fallot (n = 24, 45%), interrupted aortic arch (n = 10, 19%), ventricular septal defect (n = 5, 9%), double outlet right ventricle (n = 4, 8%), and coarctation of the aorta (n = 4, 8%). Other cardiac defects were rarely associated with 22q11.2 deletion. One fetus had persistent truncus arteriosus, one had aortic stenosis, and one had hypoplastic right heart syndrome. Two fetuses had normal intracardiac anatomy with an isolated right aortic arch, and one had an isolated bilateral superior vena cava. Conclusion A variety of congenital heart diseases were seen during the prenatal period. Conotruncal cardiac defects except transposition of great arteries were strongly associated with 22q11.2 deletion. When such anomalies are diagnosed by fetal echocardiography, genetic testing for 22q11.2 deletion should be offered. Even if less frequent deletion-related cardiac defects are detected, other related anomalies, such as thymic hypoplasia or aplasia, should be evaluated to rule out a 22q11.2 deletion. PMID:24596813

    To determine the proportion of patients with type 2 diabetes with and without cardiovascular disease achieving the main cardiovascular goals. Cross-sectional study. A regional health district in a European country, Spain. Year: 2013. Adult patients diagnosed with type 2 diabetes with and without cardiovascular disease. Study using secondary data obtained from electronic records of clinical history. Haemoglobin A1c, blood pressure, LDL cholesterol, smoking and medication were covered. n=49,658 RESULTS: The proportion of patients with diabetes achieving cardiovascular goals (among those with recent measurement) was: haemoglobin A1c 68.8% (CI95%:68.2%-69.4%), blood pressure 74.3% (CI95%:73.9%-74.7%), LDL cholesterol 59.8% (CI95%:59.0%-60.6%), tobacco 80.2% (CI95%:79.6%-80.8%). Only 40%-67% of patients has recent measurement. Only 48.0% (CI95%: 46.6%-49.4%) of patients who needed statins were receiving them. Higher proportion of patients with cardiovascular disease were achiving goals. Differences were small but significant. Cardiovascular goals were measured in around half of patients with diabetes. Proportion of patients achiving cardiovascular goals were similar to published and best in patients with cardiovascular disease but it could improve. This points to prioritising interventions in this group of patients at very high risk, improving the implementation of guidelines and patient adherence. Copyright © 2015 SESPAS.

    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.

    To assess the associations of obesity with newly diagnosed and previously known atopic disorders in Chinese adults. 4,629 adults aged 18 years or older were recruited in Harbin, China. Among them, 1,114 were previously diagnosed atopic cases, 1,298 were newly diagnosed cases, and 2,217 non-atopic controls. Obesity and overweight are defined according to the criteria established by the Working Group on Obesity in China. The associations of obesity with known and newly diagnosed atopic disorders were assessed using logistic regressions. Obesity was significantly associated with known atopic disorders (adjusted OR = 2.41 (95% CI: 1.81, 3.22)). The association of obesity with newly diagnosed atopic cases was not as strong as that with known cases, and was not statistically significant (adjusted OR = 1.27 (95% CI: 0.94, 1.72)). The similar pattern was observed in different allergic diseases, gender and age stratifications. The association between overweight and atopic diseases were not significant. Obesity is strongly associated with previously diagnosed atopic cases but not so with newly diagnosed atopic cases in Chinese adults. It is likely that people with atopic disorders have a higher risk of developing obesity. Our findings are important for the management of atopic disorders and chronic disease prevention among atopic disease patients.

    The aim of the study was to elicit the views and opinions of people diagnosed with serious mental illness in relation to physical activity. Ten people who were attending a community mental health centre participated in semi-structured interviews. The main results showed that participants found physical activity beneficial in terms of psychological and social well-being and perceived clear gains in relation to recovery and quality of life. Physical activity should be routinely included in plans of care and mental health policy guidelines globally should contain physical activity as a key component. Mental health policy guidelines globally should contain physical activity as a key component. The aim of the current study was to explore the subjective experiences of people diagnosed with serious mental illness (SMI) in relation to physical activity. The study was conducted using a qualitative exploratory descriptive approach. The participants (n = 10), who were outpatients attending a day centre, were interviewed to elicit their views and opinions about physical activity. The data were thematically analysed using a recognized framework. The main themes that emerged included physical activity as a meaningful activity, physical activity as a mental activity, quality of life and recovery, and perceived challenges to physical activity. The unique perspectives of service users provides fresh insights on the topic and the findings support the justification for the inclusion of physical activity in plans of care and to be contained in global mental health policy directives. © 2014 John Wiley & Sons Ltd.

    To investigate if occurrence of newly diagnosed exercise induced bronchoconstriction (EIB) would affect adolescents' ability to assess their physical activity. 99 selected adolescents with and 47 adolescents without self-reported exercise induced dyspnea were included. All of the 146 adolescents then performed a standardized exercise challenge test on a treadmill with dry-air inhalation to detect EIB. Free living physical activity was assessed during seven days with both accelerometer (objective assessment) and a validated activity diary (subjective assessment). Height, weight and subjective sleep were recorded. Out of the 146 adolescents 49 were diagnosed with EIB. Forty-six of the adolescents with EIB (35 girls and 11 boys) and 84 of the control adolescents (45 girls and 39 boys) had complete 7 day activity diary and accelerometer data. There were no differences in age, BMI and sleep between EIB and control adolescents. Boys with EIB overestimated subjective assessment compared to objective assessment more than girls with EIB. No difference was seen between control boys and girls. Furthermore, boys with EIB reported a much higher frequency of high intensity exercise than girls with EIB, but no difference was observed between control boys and girls. Adolescent boys with newly diagnosed EIB overestimated their physical activity compared to EIB girls. Caution may thus be used when choosing methods measuring level of physical activity in this group and especially when investigating gender differences. Copyright © 2017 Elsevier Ltd.

    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)

    Full Text Available Melissa S Engel,1 Lazaros K Kochilas2 1Division of Neonatology, University of Minnesota, Minneapolis, MN, 2Children’s Healthcare of Atlanta, Emory University, Atlanta, GA, USA Abstract: Congenital heart disease (CHD is one of the most common birth defects, with an incidence of nine out of every 1,000 live births. The mortality of infants with CHD has decreased over the past 3 decades, but significant morbidity and mortality continue to occur if not diagnosed shortly after birth. Pulse oximetry was recommended as a screening tool to detect critical CHD in 2011 by the American Academy of Pediatrics and the American Heart Association. Pulse oximetry is a tool to measure oxygen saturation, and based on the presence of hypoxemia, many cardiac lesions are detected. Due to its ease of application to the patient, providing results in a timely manner and without the need for calibrating the sensor probe, pulse oximetry offers many advantages as a screening tool. However, pulse oximetry has also important limitations of which physicians should be aware to be able to assess the significance of the pulse oximetry measurement for a given patient. This review aims to highlight the benefits and shortcomings of pulse oximetry within the context of screening for critical CHD and suggests future avenues to cover existing gaps in current practices.

    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%.

    Whether newly diagnosed atrial fibrillation (nAF) after stroke reflects underlying heart disease and represents an increased risk of cardioembolic stroke, or whether it is triggered by neurogenic mechanisms remains uncertain. We investigated, whether cardiovascular risk factors and echocardiographic parameters in patients with nAF are similar to patients with known AF (kAF) and differ from patients without AF. Consecutive acute ischemic stroke patients were enrolled into a prospective stroke database. All patients with echocardiography were included and univariable and multivariable testing was applied to compare clinical characteristics and echocardiographic findings among patients with nAF, kAF, and no AF. A total of 1397 patients were included (male, 62.3%; median age, 71 years). AF was present in 320 (22.9%) patients. Of those, nAF was present in 36.2% (116/320) and kAF in 63.8% (204/320). No clinical or echocardiographic factor was independently associated with detection of nAF compared with kAF but a trend toward larger left atrial diameters in patients with kAF was observed (P=0.070). In contrast, patients with nAF were more often female (Pstroke severity in patients with nAF and kAF was similar, patients without AF had less severe strokes. Stroke patients with nAF and with kAF share common cardiovascular risk factors, have similar echocardiographic findings and suffer equally severe strokes. We conclude that preexisting heart disease is the major cause of AF that is first diagnosed after stroke. © 2016 American Heart Association, Inc.

  7. 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)

    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), p<0.001) and ongoing secondary prophylaxis at follow-up (HR 0.27 (0.12 to 0.63), p=0.01) were the two most influential factors associated with MACE. Newly diagnosed RHD is associated with poor outcomes, mainly in patients with moderate or severe valve disease and no secondary prophylaxis. Published by the BMJ Publishing Group Limited.

    Physical activity after a diagnosis of breast cancer is associated with many health benefits. Health literacy has been shown to relate to physical activity, but there is limited research on this relationship. The aim of this study was to explore the relationship between health literacy and physical activity in women diagnosed with breast cancer. Specifically, we examined which of Nutbeam's 3 levels of health literacy (functional, interactive, and critical health literacy) predicted physical activity in women who have completed treatment for breast cancer. Participants were women (N = 36) who had attended a local cancer care centre for breast cancer treatment. During a telephone interview conducted 6 to 18 months after completion of treatment, women completed a measure of health literacy and reported on their engagement in physical activity. Results showed that health literacy predicted physical activity after breast cancer treatment. Of the 3 levels of health literacy proposed by Nutbeam, functional health literacy was shown to be the most important predictor of physical activity. These findings highlight the role of health literacy in physical activity in women diagnosed with breast cancer and have implications for targeted supportive physical activity interventions.

    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 Aide dans la Maladie d'Alzheimer (AIDMA) study was conducted to determine whether a psycho-educational programme (PEP) for primary caregivers in addition to standard anti-dementia drugs for patients improves caregivers' psychological condition and patients' activities of daily life. Multicentre randomised controlled intervention trial. One hundred and sixty-seven dyads 'patient-caregiver' were recruited from 15 French memory clinics and randomised in two parallel groups. The intervention group was offered the PEP in 12 group sessions for 3 months. The control group had usual care. Patients in both groups with mild to moderate Alzheimer's disease (AD) were diagnosed and treated with pharmacotherapy. Patients' primary efficacy variable was functional status assessed with the Disability Assessment Scale for Dementia (DAD) scale. Alzheimer Disease Assessment Scale (ADAS-Cog) and Neuropsychiatric Inventory (NPI) were secondary criteria. Caregivers' first outcome measure was depressive symptoms assessed with the Montgomery and Asberg Depression Rating Scale (MADRS) scale. Zarit scale, Sense of Competence Questionnaire (SCQ) and Visual Analogue Scales (VAS) were secondary criteria. Assessment was done at baseline, 3 months (M3, end of intervention) and 6 months (M6). Patients' stabilisation was observed in both groups. In caregivers, significant improvement in disease understanding at M3 (p = 0.007) and M6 (p = 0.0001) and in ability to cope with care-recipients' disease at M6 (0.02) was evidenced. The PEP had no additional impact on patients but carers developed more effective disease understanding and ability of coping. Results support the idea that the PEP although improving caregivers' condition is not sufficient to improve patients' activities in daily life which requires additional individually tailored interventions provided by professionals.

    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.

    Development of internal fistula due to extramural spread of inflammatory bowel disease is a characteristic feature of penetrating disease in patients with Crohn disease. The ''star sign'' is a radiological finding of internal fistula that has previously been described in the gastroenterology literature in adult Crohn disease patients undergoing MR enteroclysis. The goal of this paper is to review the clinical and imaging features of penetrating disease in pediatric Crohn disease patients, highlighting the star sign as a useful diagnostic tool for diagnosing internal fistula in children by MR enterography. The recognition of penetrating complications by MR imaging can have important therapeutic and prognostic implications. (orig.)

    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

    Mucosal-associated Escherichia coli may play a role in the pathogenesis of inflammatory bowel diseases (IBDs). In this study we assessed mucosal-associated E. coli in adults at the time of first diagnosis. E. coli were isolated from 59 right colon biopsies of 34 newly diagnosed adult IBD patients (Crohn's disease [CD] = 23, ulcerative colitis [UC] = 11) and 25 healthy controls (HC). Strains were serotyped, phylotyped into A, B1, B2, or D, and tested for their ability to survive in macrophages. The presence of various virulence factors was also assessed. The fimH subunit of type 1 fimbriae was sequenced and phylogenetically analyzed. A total of 65 E. coli were isolated from CD (29 isolates from 23 patients), UC (11 isolates from 11 patients), and HC (25 isolates from 25 subjects). All E. coli were positive for fimH, crl, and cgsA and negative for vt1, vt2, hlyA, cnf, and eae. Significant positive associations were between CD and in between CD and afae (P = 0.002), and between UC and ompA (P = 0.02), afae (P = 0.03), and USP (P = 0.04). The B2+D phylotype was significantly associated with inflammation (P = 0.04) as it was with serine protease autotransporters (SPATE), malX, ompA, and kpsMTII (P < 0.05). Macrophage survival was the highest in UC-isolated E. coli (P = 0.04). FimH amino acid substitutions N91S, S99N, and A223V were associated with IBD (P < 0.05). Adherent invasive E. coli are present at first diagnosis, suggesting that they may have a role in the early stages of disease onset. Copyright © 2010 Crohn's & Colitis Foundation of America, Inc.

    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.

    Full Text Available Background. Video capsule endoscopy (VCE is increasingly performed among the elderly for obscure bleeding. Our aim was to report on the utility of VCE to uncover unsuspected Crohn’s disease (CD in elderly patients. Methods. Retrospective review of VCE performed in elderly patients (≥70 y at a tertiary hospital (2010–2015. All underwent prior negative bidirectional endoscopies. CD diagnosis was based on consistent endoscopic findings, exclusion of other causes, and a Lewis endoscopic score (LS > 790 (moderate-to-severe inflammation. Those with lower LS (350–790 required histological confirmation. Known IBD cases were excluded. Results. 197 VCE were performed (mean age 78; range 70–93. Main indications were iron deficiency anemia (IDA, occult GI bleeding (OGIB, chronic abdominal pain, or diarrhea. Eight (4.1% were diagnosed as CD based on the aforementioned criteria. Fecal calprotectin (FCP was elevated in 7/8 (mean 580 μg/g. Mean LS was 1824. Small-bowel CD detected by VCE led to a change in management in 4/8. One patient had capsule retention secondary to NSAID induced stricture, requiring surgical retrieval. Conclusions. VCE can be safely performed in the elderly. A proportion of cases may have unsuspected small-bowel CD despite negative endoscopies. FCP was the best screening test. Diagnosis frequently changed management.

    The New Zealand Neuromuscular Disease Registry (NZ NMD Registry) is part of the TREAT NMD Alliance, an international network that provides infrastructure ensuring the most promising new therapies reach neuromuscular patients as quickly as possible. Its main aim is to ensure that the most promising new therapies reach patients as quickly as possible. From the perspective of researchers interested in trialling treatments it is useful to have data on the pool of potential research participants. From a patient's perspective it is important to know what trials they can take part in. Both of these require a confirmed molecular diagnosis in the patient. Some therapeutic strategies not only require knowledge of which gene is affected but are targeted at specific mutations within the gene. In reviewing data held in the NZ NMD Registry it was noted that, of those diagnosed with a genetic condition, only 51% have a confirmed molecular genetic diagnosis. This low rate of genetic diagnosis is a potential barrier to research participation but can be removed with improved genetic technology and with changes in knowledge about and attitudes towards genetic testing.

    Interstitial lung disease (ILD) in infants is rare. Clinical and radiological features are often non-specific, and overlap with growth disorders and infection. In infants with severe respiratory compromise, lung biopsy is often necessary to guide acute management, but the risk and diagnostic yield of this procedure is incompletely understood. To retrospectively review infants undergoing open lung biopsy for suspected ILD at a large referral center; to determine morbidity and mortality related to the procedure; and to describe subsequent diagnosis and outcome. Lung biopsies performed in infants (aged Diagnoses seen were similar to those reported by the ChILD network. Histopathological diagnosis was not compatible with life in the absence of lung transplant in 6/27 (22%) of infants. Of the 14 children longitudinally followed up (median 0.5 (0.4 - 5.81) years), only four continued to require supplemental oxygen. Lung biopsy in infants with suspected ILD is safe, and histopathological diagnosis frequently assists treatment decisions, particularly with regard to withdrawal of care. © 2015 Wiley Periodicals, Inc.

    Autosomal dominant polycystic kidney disease (ADPKD) in children is often regarded as a benign condition. However, previous studies pointed out renal-related anomalies which may benefit from early appropriate treatments. This study was conducted to evaluate the prevalence and severity of early renal dysfunction in ADPKD children. An extensive renal evaluation was performed in 52 consecutive ADPKD patients diagnosed either from prenatal screening or post-natal ultrasound (US) examination (54 % males, mean age 10 ± 4 years [1-17]). Three patients had both systolic (SBP) and diastolic (DBP) blood pressure above the 95th percentile, one patient had a "high normal" DBP, and one child was treated with an angiotensin-converting enzyme inhibitor (ACEI). The mean ± SD glomerular filtration rate (GFR ml/min per 1.73 m(2), inulin clearance) was 115 ± 26 [47-168] but six children (12 %) had a GFR 135). Microalbuminuria (2 20 mg/mmol). Early renal manifestations are frequent in ADPKD children, including hypertension in 6 %, albuminuria in 58 %, and decreased GFR in 12 %. In conclusion, renal function in children with ADPKD should be regularly assessed in order to manage early renal dysfunction and even consider further therapeutic intervention.

    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 pylori-negative 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.

    Human immunodeficiency virus (HIV) the causative agent of Acquired immunodeficiency syndrome (AIDS) is an important cause of renal diseases in sub-Saharan Africa. There is paucity of studies on the burden of chronic kidney disease (CKD) among patients with HIV/AIDS in the North-Central zone of Nigeria. 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.

    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.

    The retrieval deficit hypothesis on memory impairment in patients with Parkinson's disease (PD) implies a selective impairment in recall of learned material with normal encoding, retention, and recognition. This hypothesis has been challenged by new data. We have therefore investigated verbal memory and learning in a large sample of newly diagnosed, drug naïve, non-demented patients with PD. From a sample of patients with PD from the Norwegian ParkWest study, 133 PD patients and 133 controls matched on sex, age, and education were included. The California Verbal Learning Test-2 (CVLT-2) was used to assess verbal memory. Patients performed significantly worse than controls on free and cued recall as well as on recognition memory. Patients used the semantic clustering learning strategy significantly less extensively than the controls and the learning slope of the PD patients was significantly less steep. There was no difference in retention when controlling for encoding. Patients did not perform better on the recognition measure or on cued recall (d-prime), as compared to free recall. Executive functions explained a substantial part of the memory deficits. This study suggests that memory impairment in drug naïve early PD to a large degree is a deficit of learning/ encoding and not of retention or retrieval. An implication is that the retrieval deficit hypothesis should be moderated in its general form. Executive deficits and less extensive use of the efficient semantic clustering learning strategy had a strong impact on learning and memory. (c) 2010 APA, all rights reserved.

    Full Text Available Malabsorption, weight loss and vitamin/mineral-deficiencies characterize classical celiac disease (CD. This study aimed to assess the nutritional and vitamin/mineral status of current “early diagnosed” untreated adult CD-patients in the Netherlands. Newly diagnosed adult CD-patients were included (n = 80, 42.8 ± 15.1 years and a comparable sample of 24 healthy Dutch subjects was added to compare vitamin concentrations. Nutritional status and serum concentrations of folic acid, vitamin A, B6, B12, and (25-hydroxy D, zinc, haemoglobin (Hb and ferritin were determined (before prescribing gluten free diet. Almost all CD-patients (87% had at least one value below the lower limit of reference. Specifically, for vitamin A, 7.5% of patients showed deficient levels, for vitamin B6 14.5%, folic acid 20%, and vitamin B12 19%. Likewise, zinc deficiency was observed in 67% of the CD-patients, 46% had decreased iron storage, and 32% had anaemia. Overall, 17% were malnourished (>10% undesired weight loss, 22% of the women were underweight (Body Mass Index (BMI 25. Vitamin deficiencies were barely seen in healthy controls, with the exception of vitamin B12. Vitamin/mineral deficiencies were counter-intuitively not associated with a (higher grade of histological intestinal damage or (impaired nutritional status. In conclusion, vitamin/mineral deficiencies are still common in newly “early diagnosed” CD-patients, even though the prevalence of obesity at initial diagnosis is rising. Extensive nutritional assessments seem warranted to guide nutritional advices and follow-up in CD treatment.

    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.

    Full Text Available OBJECTIVE: 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. METHODS: 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. RESULTS: 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/Sß0-talassemia, 34 SC and 6 Sß+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%. CONCLUSIONS: 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.

    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.

    Several studies have indicated that low physical activity is associated with increased risk of cardiovascular disease (CVD) and all-cause mortality among patients with diabetes. The association between physical activity and subclinical cardiovascular changes preceding clinical events remains to be elucidated. We investigated the relationship between physical activity and arterial stiffness, an independent predictor of CVD, in patients with type 2 diabetes and controls. We included 100 patients with type 2 diabetes and 100 sex- and age-matched controls in a cross-sectional study. Arterial stiffness (carotid-femoral pulse wave velocity, cfPWV) was measured using the SphygmoCor device (AtCor Medical, Sydney, Australia). Physical activity was assessed by an accelerometer (counts per minute (cpm), Actiheart (CamNtech, Cambridge, UK)) worn by the participants for up to 6 days. High vs. low levels of physical activity was defined according to the median level of activity (cpm = 31). Sixty-five patients and 65 controls were included in the final analysis (median age 59 years, 55% men, median diabetes duration 1.9 years). Participants with low physical activity had higher cfPWV compared to participants with high physical activity: (i) Patients and controls combined: 9.3±1.7 m/s vs. 7.8±1.5 m/s, P diabetes: 9.5±1.8 m/s vs. 8.3±1.6 m/s, P = 0.02 and C) Controls: 9.0±1.4 m/s vs. 7.7±1.4 m/s, P diabetes and the effect of low activity was seen. Low physical activity is associated with increased arterial stiffness in patients recently diagnosed with type 2 diabetes and in healthy controls.

    2015-09-01

    Restless legs syndrome (RLS) mimics cannot always be differentiated from RLS/Willis-Ekbom disease (WED) based on 4 essential criteria; hence, a fifth criterion has recently been established. RLS comorbidities may provide us important clues for understanding the neurobiology of RLS/WED. Iron-dopamine connection, hypoxia pathway activation, and dopamine-opioid interaction are important pathophysiological mechanisms in RLS; this knowledge is derived from our understanding of RLS associations with a variety of medical, neurologic, and other conditions. Clinicians must formulate an RLS differential diagnosis based on history and physical examination, but laboratory tests may sometimes be needed to arrive at a correct diagnosis.

    To examine the association between physical activity (PA) and Alzheimer disease (AD) course. PA has been related to lower risk for AD. Whether PA is associated with subsequent AD course has not been investigated. In a population-based study of individuals aged 65 years and older in New York who were prospectively followed up with standard neurologic and neuropsychological evaluations (every ~1.5 years), 357 participants i) were nondemented at baseline and ii) were diagnosed with AD during follow-up (incident AD). PA (sum of participation in a variety of physical activities, weighted by the type of activity [light, moderate, and severe]) obtained 2.4 (standard deviation [SD], 1.9) years before incidence was the main predictor of mortality in Cox models and of cognitive decline in generalized estimating equation models that were adjusted for age, gender, ethnicity, education, comorbidities, and duration between PA evaluation and dementia onset. One hundred fifty incident AD cases (54%) died during the course of 5.2 (SD, 4.4) years of follow-up. When compared with incident AD cases who were physically inactive, those with some PA had lower mortality risk, whereas incident AD participants with much PA had an even lower risk. Additional adjustments for apolipoprotein genotype, smoking, comorbidity index, and cognitive performance did not change the associations. PA did not affect rates of cognitive or functional decline. Exercise may affect not only risk for AD but also subsequent disease duration: more PA is associated with prolonged survival in AD.

    Background Whether non-communicable diseases (NCDs) are diseases of poverty or affluence in low-and-middle income countries has been vigorously debated. Most analyses of NCDs have used self-reported data, which is biased by differential access to healthcare services between groups of different socioeconomic status (SES). We sought to compare self-reported diagnoses versus standardised measures of NCD prevalence across SES groups in India. Methods We calculated age-adjusted prevalence rates of common NCDs from the Study on Global Ageing and Adult Health, a nationally representative cross-sectional survey. We compared self-reported diagnoses to standardized measures of disease for five NCDs. We calculated wealth-related and education-related disparities in NCD prevalence by calculating concentration index (C), which ranges from −1 to +1 (concentration of disease among lower and higher SES groups, respectively). Findings NCD prevalence was higher (range 5.2 to 19.1%) for standardised measures than self-reported diagnoses (range 3.1 to 9.4%). Several NCDs were particularly concentrated among higher SES groups according to self-reported diagnoses (Csrd) but were concentrated either among lower SES groups or showed no strong socioeconomic gradient using standardized measures (Csm): age-standardised wealth-related C: angina Csrd 0.02 vs. Csm −0.17; asthma and lung diseases Csrd −0.05 vs. Csm −0.04 (age-standardised education-related Csrd 0.04 vs. Csm −0.05); vision problems Csrd 0.07 vs. Csm −0.05; depression Csrd 0.07 vs. Csm −0.13. Indicating similar trends of standardized measures detecting more cases among low SES, concentration of hypertension declined among higher SES (Csrd 0.19 vs. Csm 0.03). Conclusions The socio-economic patterning of NCD prevalence differs markedly when assessed by standardized criteria versus self-reported diagnoses. NCDs in India are not necessarily diseases of affluence but also of poverty, indicating likely under-diagnosis and

    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.

    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. Conclusion Hospital admission data

    The use of medical imaging in diagnosing brain disease is growing. The challenges are related to the big size of data and complexity of the image processing. High standard of hardware and software are demanded, which can only be provided in big hospitals. Our purpose was to provide a smart cloud system to help diagnosing brain diseases for hospital with limited infrastructure. The expertise of neurologists was first implanted in cloud server to conduct an automatic diagnosis in real time using image processing technique developed based on ITK library and web service. Users upload images through website and the result, in this case the size of tumor was sent back immediately. A specific image compression technique was developed for this purpose. The smart cloud system was able to measure the area and location of tumors, with average size of 19.91 ± 2.38 cm2 and an average response time 7.0 ± 0.3 s. The capability of the server decreased when multiple clients accessed the system simultaneously: 14 ± 0 s (5 parallel clients) and 27 ± 0.2 s (10 parallel clients). The cloud system was successfully developed to process and analyze medical images for diagnosing brain diseases in this case for tumor.

    Proton pump inhibitors (PPIs) are commonly used to treat gastrointestinal diseases. Incidence of hypersensitivity reactions to PPIs has risen, likely because of increased consumption. Their diagnosis is difficult, with skin tests (STs) presenting low sensitivity, making it necessary to perform drug provocation tests (DPTs). The value of in vitro tests for the diagnosis of immediate reaction to PPI is unclear. To analyze the diagnostic value of the basophil activation test (BAT) in a group of patients diagnosed with immediate allergy to omeprazole. The study included 42 patients with confirmed immediate allergic reactions to omeprazole confirmed by positive ST results or DPT results and 22 age- and sex-matched subjects tolerant to PPIs. BAT was performed with omeprazole, pantoprazole, and lansoprazole using CD63 and CD203c as activation markers. ST sensitivity was 66.7% with a specificity of 100%. BAT using CD63 with a stimulation index of more than 2 as positive revealed a sensitivity of 73.8%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 66.7%. BAT was positive in 57.1% of patients with negative ST result, and thus by combining ST and BAT we can correctly diagnose 85.7% of patients with immediate allergy to omeprazole. BAT represents a complementary tool for inclusion in the allergological workup for patients allergic to omeprazole. When combined with ST, it can be of value to guide the clinician as to whether to perform a DPT. Copyright © 2017 American Academy of Allergy, Asthma & Immunology. Published by Elsevier Inc.

    Diseases of the gallbladder and the bile duct system can generally be divided in congenital and acquired diseases. Important congenital diseases are biliary atresia and choledochal cysts. Acquired diseases can be divided in gallstone diseases, inflammatory diseases and neoplastic diseases. Imaging of the biliary system should include the gallbladder as well as the intra- and extrahepatic bile ducts. Radiologic examinations include the transabdominal ultrasound, which has a high value in acute disease and computed tomography as a widely available cross sectional imaging modality. Magnetic resonance imaging did greatly benefit from the development of MR cholangiography (MRC). MR including MRC or MRCP (MR cholangiopancreatography) as it is called if the pancreatic duct is imaged simultaneously can be considered as a first line, non invasive imaging modality. Especially for imaging of the biliary tree, it is superior to CT and sonography. (orig.)

    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 benefits from condom use (p benefits of condom use (p = 0.016), and perceived risk for HIV (p = 0.033). They explained 36% of 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.

    Cross-sectional. To describe physical activity level and fracture rates in adults with idiopathic scoliosis, diagnosed before maturity, and to compare with a control group. A previous study found a lower level of sporting activities in adults treated for idiopathic scoliosis compared with controls. Other studies have shown a lower bone mass in adults with idiopathic scoliosis compared with controls. One thousand two hundred seventy-eight adults (aged 18-71 yr) with idiopathic scoliosis and 214 controls (aged 18-70 yr) were included and answered the International Physical Activity Questionnaire - Short Form (IPAQ-SF) and questions about previous fractures. The three scoliosis treatment groups (untreated n = 360, brace n = 460, and surgically treated n = 458) were compared. Furthermore, a comparison based on onset (juvenile n = 169 or adolescent n = 976) was performed. Achieved weekly moderate activity level and metabolic equivalent task (MET) minutes/week were assessed for patients and controls. Statistical comparisons were made with analysis of covariance with adjustments for age, body mass index, and sex. The proportion achieving weekly moderate activity level was 962 out of 1278 for individuals with idiopathic scoliosis (75%) and 157 out of 214 (73%) for controls (P = 0.40). The scoliosis patients reported 2016 MET-minutes/week (median value) and the controls 2456 (P = 0.06). Fracture rates did not differ (P = 0.72). Fewer surgically treated individuals achieved moderate activity level (P = 0.046) compared with the untreated and the previously braced individuals. No difference was seen regarding MET-minutes/week (P = 0.86). No differences were seen between individuals with a juvenile onset compared with individuals with an adolescent onset (all P ≥ 0.05). Adults with idiopathic scoliosis have similar physical activity level and do not sustain more fractures compared with controls. Adults with surgically treated

    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.

    Objective: To evaluate the color Doppler ultrasound in diagnosing venous diseases of lower extremity, and to compare it with DSA.Methods: By using color Doppler ultrasound (CDUS) apparatus, two-dimensional spectrum, color Doppler flow image, pulse wave Doppler and Valsalva examination were performed in 48 patients with suspected venous diseases of lower extremity. The CDUS findings were compared with DSA findings. Results: Of 48 cases with suspected lower extremity venous diseases, deep vein thrombosis formation was confirmed in 27, among them 15 were accompanied with lower extremity deep venous valvular incompetence, 8 were complicated by lower extremity varicosity and 2 were associated with both conditions. Another one had cyst in the left popliteal fossa and popliteal venous thrombosis. Decreased blood flow in iliac veins was found in some cases. Pure lower extremity venous valvular incompetence was seen in 5 cases and pure lower extremity superficial varicosity in 6 cases. Six cases suffered both valvular incompetence and superficial varicosity. CDUS showed normal findings in 4 cases, of them DSA demonstrated compressed iliac vein in 2. When taking DSA as golden standard, the accuracy of CDUS was 95.83%. By using the uniformity test, Kappa value was 0.65. Conclusion: CDUS is of great clinical usefulness in diagnosing venous diseases of lower extremity as well as in evaluating the therapeutic effect. (authors)

    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. © 2016 The Author(s).

    The aim of this study was to compare the prevalence of the metabolic syndrome diagnosed using three different definitions and to evaluate its associations with ischemic heart disease in Kaunas adult population. MATERIAL AND METHODS. Data of preventive screening carried out in Kaunas in 2001-2002 according to the MONICA study protocol were used for analysis; a total of 1336 persons aged 35-64 years (603 men and 733 women) were recruited. The metabolic syndrome was defined by the World Health Organization, Adult Treatment Panel III, and International Diabetes Federation definitions. Ischemic heart disease was diagnosed based on the following criteria: a documented history of myocardial infarction, angina pectoris, or ischemic changes on electrocardiogram. RESULTS. The metabolic syndrome was identified for 11.3% of men and for 9.4% of women using the World Health Organization definition, for 19.4% of men and for 26.3% of women using the Adult Treatment Panel III definition, and for 30.0% of men and for 37.7% of women using the International Diabetes Federation definition. In male and female groups, the prevalence of the metabolic syndrome (irrespective of definition) significantly increased with age (Pmetabolic syndrome using the International Diabetes Federation definition (OR=2.30; P=0.001) and Adult Treatment Panel III definition (OR=1.97; P=0.01) and women diagnosed with metabolic syndrome using the International Diabetes Federation definition (OR=1.50; P=0.039) had a significantly higher risk of having ischemic heart disease as compared with those without the metabolic syndrome by the same definitions. The metabolic syndrome diagnosed using the World Health Organization definition was not associated with a significant risk of ischemic heart disease in men and women. CONCLUSION. In Kaunas population aged 35-64 years, the highest prevalence of the metabolic syndrome was determined according to the International Diabetes Federation definition. Usage of the

    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...

    2016-01-01

    To evaluate whether activated partial thromboplastin time (APTT) could be used in the laboratory diagnosis of hereditary or acquired angioedema (HAE or AAE) with and without C1 inhibitor (C1-INH) deficiency. In a prospective investigation, APTT and other coagulation parameters were determined in 149 adult patients with various types of angioedema and in 26 healthy participants (HP). Mean APTT was significantly shortened in HAE-C1-INH type I (p angioedema, 4/30 (13.3%) patients with nonhistaminergic angioedema and in 2/26 (7.7%) HP. Thus, a shortened APTT was obtained in 8-9 times more patients with angioedema due to C1-INH deficiency when compared to patients with various forms of angioedema with normal C1-INH and also to HP. A shortened APTT may help to diagnose HAE-C1-INH and AAE-C1-INH when determination of C1-INH is not yet available. © 2016 S. Karger AG, Basel.

    In newly diagnosed patients with Hodgkin disease and non-Hodgkin lymphoma, the value of computed tomography (CT) of the liver was assessed as regards impact on the staging process. 201 patients at two medical centers had pretreatment abdominal CT within two weeks of liver biopsy. CT sensitivity, specificity and accuracy in both groups were determined and sensitivity in both groups was very low (8%). If liver biopsy results had been omitted, reliance on CT and other clinical staging procedures alone would have led to important staging errors in 18 of these 201 patients (9%) - overstaging would have occurred twice and understaging 16 times. In 7 additional patients, the lack of demonstration by CT of documented liver disease was without clinical consequence because disseminated extranodal lymphoma was visible at other sites or at extrahepatic regions of the same CT scan. In patients with newly diagnosed Hodgkin disease and non-Hodgkin lymphoma, CT is an unreliable indicator of liver status and cannot replace liver biopsy in supplying the data required for optimal management.

    Full Text Available Infant Botulism is a form of human botulism in which ingested spores of Clostridium botulinum germinate, colonize the infant’s colon, in which they produce botulinum neurotoxin. After the toxin is absorbed, binding to peripheral cholinergic synapses occurs, causing flaccid paralysis. The incidence of infant botulism is low, but some underestimation is likely to exist: the disease is difficult to diagnose because its wide spectrum of clinical manifestations which are not pathognomic. Moreover, failure to recognise the disease is probably related to the low index of suspicion: in fact, the experience of clinicians is fundamental in recognising infant botulism. A specific project has been promote to improve knowledge of the disease by training physicians (pediatricians, neurologists, clinical toxicologists to look out for the possible presence of Infant Botulism cases and improving public awareness through a prevention program. Standardization of therapeutic protocol also by treatment with specific therapeutic measures will be disseminated. A staff of physicians specialized in Clinical Toxicology will be available, 24 hours a day and seven days/week in the Pavia Poison Centre – National Toxicology Information Center. According to the project, this Centre acts as Reference Center for the clinical diagnosis and the treatment of infant botulism for the correct recognition of typical syndrome, the early diagnosis and the possible therapy with particular attention to antidotic treatment. The National Reference Centre for Botulism at the Istituto Superiore di Sanità will offer a 24-hours diagnostic laboratory service to support diagnose in suspected cases of botulism.

    Full Text Available Severe forms of Coats’ disease are often associated with total retinal detachment, and a differential diagnosis from retinoblastoma is critically important. In such eyes, laser- and/or cryoablation is often ineffective or sometimes impossible to perform. We report a case of advanced Coats’ disease in which a rapid pathological examination of subretinal fluid was effective for the diagnosis, and external subretinal drainage combined with vitrectomy was effective in preserving the eye.

    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

    The gastric pathogen Helicobacter pylori utilizes molecular hydrogen (H2) as a respiratory substrate during colonization in the gastric mucosa. However, the link between molecular H2 and the pathogenesis of peptic-ulcer disease (PUD) and non-ulcerous dyspepsia (NUD) by the enzymatic activity of H. pylori still remains mostly unknown. Here we provide evidence that breath H2 excretion profiles are distinctly altered by the enzymatic activity of H. pylori for individuals with NUD and PUD. We subsequently unravelled the potential molecular mechanisms responsible for the alteration of H2 in exhaled breath in association with peptic ulcers, encompassing both gastric and duodenal ulcers, along with NUD. We also established that carbon-isotopic fractionations in the acid-mediated bacterial environment regulated by bacterial urease activity cannot discriminate the actual disease state i.e. whether it is peptic ulcer or NUD. However, our findings illuminate the unusual molecular H2 in breath that can track the precise evolution of PUD and NUD, even after the eradication of H. pylori infection. This deepens our understanding of the pathophysiology of PUD and NUD, reveals non-invasively the actual disease state in real-time and thus offers a novel and robust new-generation strategy for treating peptic-ulcer disease together with non-ulcer related complications even when the existing (13)C-urea breath test ((13)C-UBT) fails to diagnose.

    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.

    Full Text Available Human immunodeficiency virus (HIV infection is a common cause of chronic kidney disease (CKD in Sub-Saharan Africa. This study aims at identifying the prevalence and predictors of CKD in newly diagnosed HIV patients in Owerri, South East Nigeria. This was a cross-sectional study consisting of 393 newly diagnosed HIV-seropositive subjects and 136 age- and sex-matched seronegative subjects as controls. CKD was defined as 24-hour urine protein (24-HUP ≥0.3 g and/or glomerular filtration rate (GFR < 60 ml/min. Subjects were recruited from the HIV clinic and the Medical Outpatient Department of Federal Medical Centre, Owerri. Clinical and anthropometric data were collected. Relevant investigations were performed, including HIV screening and relevant urine and blood investigations. The mean age of the HIV subjects was 38.84 ± 10.65 years. CKD was present in 86 (22.9% HIV subjects and 11 (8.l % controls. Low waist circumference (WC, high serum creatinine, high spot urine protein/creatinine ratio (SUPCR, high 24-HUP/creatinine Ratio (24-HUPCR, high 24-HUP/osmolality Ratio (24-HUPOR predicted CKD in HIV subjects. CKD prevalence is high (22.9% among newly diagnosed HIV patients in South East Nigeria. The predictors of CKD included WC, serum creatinine, SUPCR, 24-HUPCR, and 24-HUPOR.

    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.

    At an incidence of 1:500, celiac disease (formerly sprue) is an important differential diagnosis in patients with malabsorption, abdominal discomfort, diarrhea and food intolerances. Celiac disease can induce a broad spectrum of both gastrointestinal and extraintestinal symptoms, e.g. dermatitis herpetiformis (Duhring's disease). A variety of oligo- and asymptomatic courses (e.g. anemia, osteoporosis, depression) through to refractory collagenic celiac disease are seen. In HLA-DQ2 and -8 predisposed individuals, celiac disease is provoked by contact with wheat gliadin fractions through a predominantly Th1 immune response and an accompanying Th2 response, which can eventually lead to villous atrophy. Using appropriate serological tests (IgA antibodies against tissue-transglutaminase, endomysium and deamidated gliadin peptides) under sufficient gluten ingestion, the diagnosis can be made more reliably today than previously. The same IgG-based serological tests should be used in the case of IgA deficiency. Diagnosis can either be made in children and adolescents with anti-transglutaminase titers exceeding ten times the standard for two of the above-mentioned serological markers and HLA conformity or it is made by endoscopy and histological Marsh classification in adults and in cases of inconclusive serology. If clinically tolerated, gluten challenges are indicated in patients that already have reduced gluten intake, in borderline serological results, discordance between serological and histological results or in suspected food allergy. The diagnosis of celiac disease needs to be definitive and robust before establishing a gluten-free diet, since lifelong abstention from gluten (gliadin rare cases, accompanied by enteropathy-associated T-cell lymphoma.

    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.

    Pastor, Catherine M; Müllhaupt, Beat; Stieger, Bruno

    2014-04-01

    The expression and transport functions of organic anion transporters are modified in liver diseases, and therefore the vascular clearances of endogenous and exogenous organic anions that are taken up by these transporters have been used to assess liver diseases in patients. More recently, liver imaging with hepatobiliary contrast agents, tracers, and dyes that cross hepatocytes through the organic anion transporting polypeptides (OATPs)-multidrug resistance-associated proteins (MRPs) pathway were developed to detect and characterize focal lesions and to assess the severity of diffuse liver diseases. This review focuses mainly on magnetic resonance imaging and highlights the growing interest in imaging the OATPs-MRP2 pathway to better understand liver diseases. Imaging provides noninvasive measurements of tissue concentrations that result from the interplay between influx and efflux membrane transport systems in normal or injured hepatocytes. Imaging with magnetic resonance hepatobiliary contrast agents improves the detection and the characterization of hepatic focal lesions. New developments of imaging to assess liver function and understand the hepatocellular concentrations of contrast agents are discussed.

    A previous MSMR report found that 42.8% of all incident (first-time) urinary tract infections (UTIs) in males, but only 0.4% of such UTIs in females, were diagnosed as "urethritis, unspecified" (ICD-9: 597.80). This study explored the possibility that many of the diagnoses of urethritis in males represented sexually transmitted infections (STIs), even though ICD-9: 597.80 is explicitly reserved for cases of urethritis that are deemed to not be sexually transmitted. Examined were relationships between diagnoses of urethritis, diagnoses of STIs, and recurrent diagnoses of UTIs. Male service members who received a diagnosis of "urethritis, unspecified" (ICD-9: 597.80) had an increased risk of a subsequent UTI diagnosis, especially of "urethritis, unspecified," compared to all male service members. Most service members who were diagnosed with "urethritis, unspecified" had no documented diagnoses of an STI in their Military Health System health records; however, recurrent UTIs were more common among service members who did have documented STIs. The most commonly diagnosed STIs in this study were "other non-gonococcal urethritis" (which includes that caused by Chlamydia trachomatis) and gonorrhea.

    Full Text Available The pattern of liver diseases has radically changed in our country over the last few decades. We prospectively collected data on the newly-diagnosed cases of chronic liver diseases in a region of southern Italy after about a decade from the last epidemiological study. We conducted a multicentric prospective study that enrolled 631 patients from 21 Liver Centers of the Campania region (Southern Italy at their first hospital admission or at their first outpatient visit. In our cohort of 631 patients (367 males, 263 females, 397 (62.9% were hepatitis C virus (HCV positive, 75 (11.9% were hepatitis B virus (HBV positive, 8 (1.3% were co-infected by HBV and HCV, 73 (11.6% had an alcoholic liver disease and 64 (10.1% had a nonalcoholic fatty liver disease. HBV infection was present in young people with a higher-than-expected prevalence, despite the vaccination program which should have involved this population. HCV chronic hepatitis still remains the most common cause of liver disease in our region. HBV infection still continues to represent a health problem in young people, despite the vaccination program.

    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.

Methods: By using a nonselective metagenomics approach, the general bacterial composition in mucosal biopsies from the ileum and the colon of five subjects, four patients with different phenotypes of CD, and one noninflammatory bowel disease control, was characterized. After partial 16S ribosomal RNA (rRNA gene sequencing, BLAST homology searches for species identification and phylogenetic analysis were performed.Results: An overall biodiversity of 106 different bacterial operational taxonomic units (OTUs was detected in the cloned libraries. Nearly all OTUs belonged to the phylae Bacteroidetes (42% in CD, 71% in the control or Firmicutes (42% in CD, 28% in the control, except for some OTUs that belonged to the phylum Proteobacteria (15% in CD, 0% in the control and a few OTUs that could not be assigned to a phylum (2% in CD, 1% in the control.Conclusion: Based on the high incidence of inflammatory bowel disease (IBD in Norway, this pilot study represents a relevant determination of the gut microbiota in Norwegian patients compared to previous findings in other countries. The bacterial profile of Norwegian CD patients was found to be similar

    Full text: A 49-year-old male presented with a two year history of progressively worsening akinetic rigid syndrome. After a number of non-specific findings on PET, MRI and CT scans of the brain, a clinical diagnosis was made of Parkinson's disease, and treatment with Sinemet was commenced. The patient's symptoms, however, were not sufficiently relieved and a change in medication was considered. However, after much persistence from the patient and his family in seeking a number of neurological opinions, a 12J[-metaiodobenzylguanidine (MIBG) cardiac study was requested to attempt to confirm the diagnosis of Parkinson's disease. The patient's medication was ceased for seven days prior to the study, and the patient was pre-treated with IO ml of potassium iodide one hour prior to '231-MIBG administration, to protect the thyroid. 185MBq of '231 M IBG was administered intravenously and planar and SPECT images of the chest were acquired at fifteen minutes and three hours post injection. A heart-to-mediastinum (H-to-M) ratio was calculated at both fifteen minutes and three hours post injection, to quantify the cardiac uptake of the tracer. The images demonstrated reduced uptake on the early images (H-to-M ratio of 0.75 [normal value - 1.52]) and further reduced uptake on the delayed images (H-to-M ratio of 0.68). This reduced cardiac uptake is associated with Parkinson's disease, and provided sufficient evidence to confirm the initial clinical suspicion. As a result, the patient's medication dosage is currently being reviewed, with more invasive therapies being considered.

    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

    Full Text Available Objective: The effect of Celiac Disease (CD on children’s bone is the decrease in bone mineral density (BMD. Osteoporosis is a consequence of this decrease and usually manifests in adult ages. Studies in CD patients generally show that bone density of these patients can be different at the same ages for the same duration of disease. The aim of this study is to investigate the relationship between age and bone mineral density of CD patients at first diagnosis. Material and Methods: Ninety one patients (M/F: 36/55; age range: 3-16; mean age: 9.6±3.5 with diagnosis of CD were included in the study. BMD survey from L1-L4 lumbar spine and total hip of the patients was evaluated at presentation. We evaluated the patients in 3 groups according to their ages: Group 1: pre-school (3-7 years old, Group 2: elementary school (8-11 years old and Group 3: adolescent (12-16 years old. Results were compared using Student’s t test and correlation analysis. Results: The mean disease duration of the patients was 16.4±16.3 months. Mean height and weight of the patients were 124.8±17.9 cm and 27±9.3 kg, respectively and height and weight of 37 patients were in ≤ 3. percentile according to age. The BMD values of both lumbar spine and total hip and Z-scores of lumbar region were in mild correlation with age (r>0.5. There was significant difference between mean ages of patients with low bone mass for chronological age and normal bone densitometry values (p<0.05. There were 27, 36 and 28 patients in Group 1, Group 2 and Group 3, respectively. The difference between mean BMD values of these groups were statistically significant (p<0.05. The mean values of lumbar Z- scores of patients were -1.08±1.27, -1.42±1, -1.86±1.14, respectively for these three groups. Conclusion: Bone mineral densities of CD patients in childhood were lower in elder children at the time of diagnosis. This confirms the opinion that the diagnosis at earlier age results better treatment

    Disease diagnosis is conducted with a machine learning method. We have proposed a novel machine learning method that hybridizes support vector machine (SVM), particle swarm optimization (PSO), and cuckoo search (CS). The new method consists of two stages: firstly, a CS based approach for parameter optimization of SVM is developed to find the better initial parameters of kernel function, and then PSO is applied to continue SVM training and find the best parameters of SVM. Experimental results indicate that the proposed CS-PSO-SVM model achieves better classification accuracy and F-measure than PSO-SVM and GA-SVM. Therefore, we can conclude that our proposed method is very efficient compared to the previously reported algorithms.

    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.

    Little is known about changes in the imaging appearances of the bowel and mesentery over time in either pediatric or adult patients with newly diagnosed small bowel Crohn disease treated with anti-tumor necrosis factor-alpha (anti-TNF-α) therapy. To define how bowel ultrasound findings change over time and correlate with laboratory inflammatory markers in children who have been newly diagnosed with pediatric small bowel Crohn disease and treated with infliximab. We included 28 pediatric patients treated with infliximab for newly diagnosed ileal Crohn disease who underwent bowel sonography prior to medical therapy and at approximately 2 weeks, 1 month, 3 months and 6 months after treatment initiation; these patients also had laboratory testing at baseline, 1 month and 6 months. We used linear mixed models to compare mean results between visits and evaluate whether ultrasound measurements changed over time. We used Spearman rank correlation to assess bivariate relationships. Mean subject age was 15.3±2.2 years; 11 subjects were girls (39%). We observed decreases in mean length of disease involvement (12.0±5.4 vs. 9.1±5.3 cm, P=0.02), maximum bowel wall thickness (5.6±1.8 vs. 4.7±1.7 mm, P=0.02), bowel wall color Doppler signal (1.7±0.9 vs. 1.2±0.8, P=0.002) and mesenteric color Doppler signal (1.1±0.9 vs. 0.6±0.6, P=0.005) at approximately 2 weeks following the initiation of infliximab compared to baseline. All laboratory inflammatory markers decreased at 1 month (P-valuesinfliximab, when adjusted for age, sex, azathioprine therapy, scanning radiologist and baseline short pediatric Crohn's disease activity index score. The ultrasound appearance of the bowel changes as early as 2 weeks after the initiation of infliximab therapy.

We performed a cross-sectional study of adults diagnosed with IBD in childhood or adolescence at Children's Hospital in Winnipeg, Manitoba from January 1978 through December 2007. Participants (n = 112) answered a semi-structured questionnaire on educational achievements, employment, and marital status. Patients were matched for age and sex with random healthy individuals from the 2012 Canadian Community Health Survey (controls, 5 per patient). Conditional binary logistic regression and random-effects ordinal logistic regression models were used for analysis. Patients were followed for a mean duration of 14.3 years (range, 3.1-34.5 years). Persons with IBD were more likely to earn more money per annum and attain a post-secondary school degree or receive a diploma than controls (odds ratio, 1.72; 95% confidence interval, 1.13-2.60; P education levels than individuals without IBD. This observation should provide reassurance to children with IBD and their parents. ClinicalTrials.gov number: NCT02152241. Copyright © 2017 AGA Institute. Published by Elsevier Inc.

    Full Text Available Fuzzy inference systems (FIS enable automated assessment and reasoning in a logically consistent manner akin to the way in which humans reason. However, since no conventional fuzzy set theory is in the Boolean frame, it is proposed that Boolean consistent fuzzy logic should be used in the evaluation of rules. The main distinction of this approach is that it requires the execution of a set of structural transformations before the actual values can be introduced, which can, in certain cases, lead to different results. While a Boolean consistent FIS could be used for establishing the diagnostic criteria for any given disease, in this paper it is applied for determining the likelihood of peritonitis, as the leading complication of peritoneal dialysis (PD. Given that patients could be located far away from healthcare institutions (as peritoneal dialysis is a form of home dialysis the proposed Boolean consistent FIS would enable patients to easily estimate the likelihood of them having peritonitis (where a high likelihood would suggest that prompt treatment is indicated, when medical experts are not close at hand.

    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.

    Full Text Available The material for microscopic examination were blood, bone marrow, cerebrospinal fluid, lymph node puncture, feces, duodenal contents and bile, urine, sputum, urogenital tract secretions, tissue biopsies, smears from the mucous membranes of the mouth, tonsils, nose, etc. The final diagnosis of helminth infections can be established only on the basis of the positive findings of laboratory research. The basic method of laboratory diagnosis of these invasions is the detection of helminth eggs or larvae. The material for the research is the feces, the contents of the duodenum, blood, sputum, tissue biopsies, and other materials. Slides of blood microscopy are usually prepared on glass slides, their quality and purity greatly impact the effectiveness of detection and identification of blood parasites. The material from leishmaniasis patients is studied under immersion; Leishmania locate mainly outside the cell, but often they are found in the cytoplasm of mononuclear cells and neutrophils. The number of Leishmania in a single cell can reach several tens. They are in the form of small round or oval cells ranging in size from 2.5 to 5 microns. The cytoplasm is gray-blue co­lored, the nucleus are red or red-purple, kinetoplasts are dark purple color. The presence of a nucleus and kinetoplasts is the main feature that distinguishes Leishmania from platelets, cocci, and yeast cells. In a laboratory study (painting by Romanovsky — ­Giemsa, microfilaria are colored in dark blue and resemble crimped fibers. Inside the larvae nuclear grain is easy visible. The causative agents of parasitic and infectious diseases can also be found in other biological substances of the human body: the urine, cerebrospinal fluid, bone marrow, secretion of urinary organs, duodenal contents, bile, and phlegm.

    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.

    Charcot-Marie-Tooth disease (CMT), the most common genetic neuropathy, affects about 1 in 2600 people in Norway and is found worldwide. CMT Type 1 (CMT1) has slow nerve conduction with demyelinated Schwann cells. Autosomal dominant CMT Type 1B (CMT1B) results from mutations in the myelin protein zero gene which directs the synthesis of more than half of all Schwann cell protein. This gene was mapped to the chromosome 1q22-1q23.1 borderline by fluorescence in situ hybridization. The first 7 of 7 reported CMT1B mutations are unique. Thus the most effective means to identify CMT1B mutations in at-risk family members and fetuses is to sequence the entire coding sequence in dominant or sporadic CMT patients without the CMT1A duplication. Of the 19 primers used in 16 pars to uniquely amplify the entire MPZ coding sequence, 6 primer pairs were used to amplify and sequence the 6 exons. The DyeDeoxy Terminator cycle sequencing method used with four different color fluorescent lables was superior to manual sequencing because it sequences more bases unambiguously from extracted genomic DNA samples within 24 hours. This protocol was used to test 28 CMT and Dejerine-Sottas patients without CMT1A gene duplication. Sequencing MPZ gene-specific amplified fragments identified 9 polymorphic sites within the 6 exons that encode the 248 amino acid MPZ protein. The large number of major CMT1B mutations identified by single strand sequencing are being verified by reverse strand sequencing and when possible, by restriction enzyme analysis. This protocol can be used to distringuish CMT1B patients from othre CMT phenotypes and to determine the CMT1B status of relatives both presymptomatically and prenatally.

    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.

    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

    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.

    Systemic Lupus Erythematosus is systematic auto-immune disease characterized by abnormal activation of B cell with production of autoantibodies. Due to its heterogeneous course, there is a need for new markers to help in diagnosing and monitoring disease activity. The aim of this study was to identify the immunopathological role of CD19 and CD81 expression in patients with SLE and their correlation with the disease activity. Peripheral blood (PB) was collected from 40 SLE patients (20 active and 20 inactive) and 20 controls. All were subjected to CBC, Anti-ds DNA, Redial immunodiffusion (RID) for C3 and C4 as activity markers, and detection of CD19 and CD81 surface expression using flow cytometry. CD19 and CD81 were significantly reduced and correlated with disease activity. It is concluded that CD 19 and CD 81 are potential markers for diagnosing and monitoring SLE patients.

    Purpose. To describe the distribution of ocular variables, risk factors, and disease severity in newly diagnosed ocular hypertension (OH) or open-angle glaucoma (OAG). Methods. Eligible subjects underwent a complete history and examination. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) obtained from multiple logistic regression models were used to compare OAG to OH and advanced to early/moderate OAG. Results. 405 subjects were enrolled: 292 (72.1%) with OAG and 113 (27.9%) with OH. 51.7% had early, 27.1% moderate, and 20.9% advanced OAG. The OR for OAG versus OH was 8.19 (P < 0.0001) for disc notch, 5.36 (P < 0.0001) for abnormal visual field, 1.45 (P = 0.001) for worsening mean deviation, 1.91 (P < 0.0001) for increased cupping, 1.03 for increased age (P = 0.030), and 0.36 (P = 0.010) for smoking. Conclusions. Increased age was a risk for OAG, and smoking decreased the risk of OAG compared to OH. Almost half of the OAG subjects had moderate/advanced disease at diagnosis. PMID:21869921

    2017-12-01

    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.

    Macrophage activation syndrome is described as a "clinical syndrome of hyperinflammation resulting in an uncontrolled and ineffective immune response" in the context of an autoinflammatory or rheumatic disease. Current associations of macrophage activation syndrome with autoimmune disease most notably include a host of rheumatological conditions and inflammatory bowel disease. Epidemiological studies have shown that macrophage activation syndrome is precipitated by autoimmune disease more commonly than previously thought. Diagnosing the precipitating factor is essential for effective treatment and prognosis. We report a case of a six year old girl with coeliac disease diagnosed after two episodes of secondary haemophagocytic lymphohistiocytosis. Her condition only responded to treatment once the patient was placed on a gluten free diet. Further immunological testing confirmed anti-transglutaminase and anti-endomysial antibodies, however histological biopsy was deemed inappropriate due to the severity of her condition. She has remained stable with no further episodes of macrophage activation syndrome since commencing a gluten free diet. This case report is the first literature that links macrophage activation syndrome to coeliac disease and highlights the challenge of diagnosing coeliac disease with unusual features such as associated prolonged fever. Clinicians should have a low threshold for screening children with other autoimmune diseases for coeliac disease.

    Full Text Available Background - Celiac disease is an autoimmune systemic disorder in genetically predisposed individuals precipitated by gluten ingestion. Objective - In this study, we aimed to determine asymptomatic spike-and-wave findings on electroencephalography in children with celiac disease. Methods - A total of 175 children with the diagnosis of celiac disease (study group and 99 age- and sex-matched healthy children as controls (control group were included in the study. In order to determine the effects of gluten free diet on laboratory and electroencephalography findings, the celiac group is further subdivided into two as newly-diagnosed and formerly-diagnosed patients. Medical histories of all children and laboratory findings were all recorded and neurologic statuses were evaluated. All patients underwent a sleep and awake electroencephalography. Results - Among 175 celiac disease patients included in the study, 43 were newly diagnosed while 132 were formerly-diagnosed patients. In electroencephalography evaluation of patients the epileptiform activity was determined in 4 (9.3% of newly diagnosed and in 2 (1.5% of formerly diagnosed patients; on the other hand the epileptiform activity was present in only 1 (1.0% of control cases. There was a statistically significant difference between groups in regards to the presence of epileptiform activity in electroencephalography. Pearson correlation analysis revealed that epileptiform activity in both sleep and awake electroencephalography were positively correlated with tissue transglutaminase levels (P=0.014 and P=0.019, respectively. Conclusion - We have determined an increased epileptiform activity frequency among newly-diagnosed celiac disease patients compared with formerly-diagnosed celiac disease patients and control cases. Moreover the tissue transglutaminase levels were also correlated with the presence of epileptiform activity in electroencephalography. Among newly diagnosed celiac disease patients

    Depression may potentially impair the clinical course of Alzheimer's disease (AD). Thus, the aim of this study was to investigate cognitive progression of AD patients with or without major depressive episode (MDE). In this 1-year longitudinal follow-up study conducted in three Italian memory clinics, 119 newly diagnosed probable AD patients of mild severity, who were not undergoing treatment with an acetyl-cholinesterase inhibitor (AChEI), and had not been treated with psychotropic drugs in the last 2 years, were included. Patients were assessed to investigate the effect of baseline and 1-year follow-up MDE (using modified DSM-IV diagnostic criteria for MDE in AD) on progression of global cognitive deterioration (using Mini-Mental State Examination (MMSE)), adjusted for confounding factors. Never being depressed was associated with a 3.1 (95%CI 1.0-10.1) increased risk of MMSE decline compared to recovered depression. Six times more patients with persistent depression had MMSE decline compared to patients with recovered depression. However, the largest odds (7.3; 95%CI 1.4-38.1) of cognitive decline was observed in patients who developed incident depression over follow-up. In conclusion, persistent or incident depression worsens cognitive outcome while no or recovered depression does not affect it in early AD patients. Copyright © 2012 Elsevier Ltd.

    To present surveillance data on advanced disease (AD) and late presentation (LP) of HIV in Spain and their determinants. We included all new HIV diagnoses notified by the autonomous regions that consistently reported such cases throughout the period 2007-2011. Coverage was 54% of the total Spanish population. Data sources consisted of clinicians, laboratories and medical records. AD was defined as the presence of a CD4 cell count CD4 cell count CD4 count at presentation was 363 (interquartile range, 161-565). Overall, 3356 (29.4%) patients met the definition of AD and 5494 (48.1%) were classified as LP. Both AD and LP increased with age and were associated with male sex and infection through drug use or heterosexual contact. All immigrants except western Europeans were more prone to AD and LP. Multivariate models disaggregated by sex showed that the effect of age and region of origin was weaker in women than in men. Despite universal health care coverage in Spain, men, immigrants and people infected through drug use or heterosexual contact seem to be experiencing difficulties in gaining timely access to HIV care.

    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.

    This study considered whether a therapy community could create an infrastructure for developing and maintaining a service delivery model grounded in a clinic-based physiotherapy model. A longitudinal clinical study was conducted to assess the abilities of participants with Parkinson disease in a 10-month community exercise program. Fifteen individuals averaging stage 3 on the Hoehn and Yahr scale, 6 years since Parkinson disease diagnosis, and 72 years old, participated. Graphical analysis of ambulation endurance demonstrated the strongest improvement over time (11%). Walking speeds, balance, and mobility showed a maintenance effect over the 10 months. The total unified Parkinson disease rating scale, activities of daily living subscale, and motor subscale remained statistically unchanged in the study. Scores on the unified Parkinson disease rating scale mentation, behavior, and mood subscale improved by 38%. None of the scores met or exceeded the minimal detectable change, MDC95 but two scores demonstrated more than 10% change. This clinical study implemented previous short-term research findings into an ongoing community wellness program for individuals with Parkinson disease. No community-based studies have demonstrated an ability to maintain a group for an extended time frame. Group exercise including forward and backward treadmill training, designed and monitored by a physical therapist, may improve or maintain functional outcomes.

  3. 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.

    Vaccination against peptides specific to Alzheimer disease may generate an immune response that could help inhibit disease and symptom progression. PubMed and Scopus were searched for clinical trial articles, review articles, and preclinical studies relevant to the field of active Alzheimer disease vaccines and raw searches yielded articles ranging from 2016 to 1973. ClinicalTrials.gov was searched for active Alzheimer disease vaccine trials. Manual research and cross-referencing from reviews and original articles was performed. First generation Aβ42 phase 2a trial in patients with mild to moderate Alzheimer disease resulted in cases of meningoencephalitis in 6% of patients, so next generation vaccines are working to target more specific epitopes to induce a more controlled immune response. Difficulty in developing these vaccines resides in striking a balance between providing a vaccine that induces enough of an immune response to actually clear protein sustainably but not so much of a response that results in excess immune activation and possibly adverse effects such as meningoencephalitis. Although much work still needs to be done in the field to make this a practical possibility, the enticing allure of being able to treat or even prevent the extraordinarily impactful disease that is Alzheimer disease makes the idea of active vaccination for Alzheimer disease very appealing and something worth striving toward.

    Full Text Available Hepatocellular adenoma is a heterogeneous group of benign neoplasms arising from hepatocellular cells and can be subclassified into four major groups based on genotypic and phenotypic characteristics. These four subtypes are hepatocyte nuclear factor (HNF 1α-inactivated, β-catenin-activated, inflammatory, and unclassified adenomas. Immunohistochemistry studies have demonstrated that since β-catenin-activated adenomas have a higher risk of malignant transformation, the identification of the subtype of adenoma remains crucial in patient management. However, malignant transformation of hepatic adenoma without β-catenin overexpression can be seen in 30-65% cases. We report a case of malignant transformation of hepatic adenoma without overexpression of β-catenin in a 31-year-old man with a known glycogen storage disease (GSD Type-1a, which was diagnosed on surveillance magnetic resonance imaging (MRI. The MRI showed a mild interval increase in one lesion with relative stability of the other adenomas. The lesion was presumed to be suspicious for a hepatocellular carcinoma (HCC and was confirmed on pathology.

  9. Regional changes in psychotropic use among Finnish persons with newly diagnosed Alzheimer's disease in 2005-2011.

    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.

    Several prediction models for fatty liver disease (FLD) are available with limited externally validation and less comprehensive evaluation. The aim was to perform external validation and direct comparison of 4 prediction models (the Fatty Liver Index, the Hepatic Steatosis Index, the ZJU index, and the Framingham Steatosis Index) for FLD both in the overall population and the obese subpopulation.This cross-sectional study included 4247 subjects aged 20 to 65 years recruited from the north of Shanxi Province in China. Anthropometric and biochemical features were collected using standard protocols. FLD was diagnosed by liver ultrasonography. We assessed all models in terms of discrimination, calibration, and decision curve analysis.The original models performed well in terms of discrimination for the overall population, with the area under the receiver operating characteristic curves (AUCs) around 0.85, while AUCs for obese individuals were around 0.68. Nevertheless, the predicted risks did not match well with the observed risks both in the overall population and the obese subpopulation. The FLI 2006 was 1 of the 2 best models in terms of discrimination (AUCs were 0.87 and 0.72 for the overall population and the obese subgroup, respectively) and had the best performance in terms of calibration, and attained the highest net benefit.The FLI 2006 is overall the best tool to identify high risk individuals and has great clinical utility. Nonetheless, it does not perform well enough to quantify the actual risk of FLD, which need to be (re)calibrated for clinical use.

    To determine the prevalence of malnutrition and its relation to various factors in community-dwelling elderly with newly diagnosed Alzheimer's disease (AD). Retrospective cross-sectional study. Memory clinic in a rural part of the Netherlands. 312 Community-dwelling AD patients, aged 65 years or older, were included. At the time the diagnosis AD was made, socio-demographic characteristics and data on nutritional status (Mini Nutritional Assessment (MNA)), cognitive function (Mini Mental State Examination (MMSE), Cambridge Cognitive Examination (Camcog)), functional status (Interview for Deterioration in Daily Living Activities in Dementia (IDDD), Barthel Index (BI)) and behaviour (Revised Memory and Behaviour Problems Checklist (RMBPC)) were assessed. Characteristics of well-nourished patients (MNA score >23.5) were compared to characteristics of patients at risk of malnutrition (MNA score 17-23.5). Linear regression analysis was performed to assess the effect of various factors on nutritional status. The prevalence of malnutrition was 0% and 14.1% was at risk of malnutrition. AD patients at risk of malnutrition were more impaired in basic and complex daily functioning than well-nourished AD patients (median IDDD score 41.5 [25th -75th percentile 38.8-48.0] versus median IDDD score 40.0 [25th -75th percentile 37.0-43.0], p = 0.028). The degree of impairment in basic and complex daily functioning (IDDD) was independently related to nutritional status (MNA) (p = 0.001, B = -0.062). One in seven community-dwelling elderly with newly diagnosed AD is at risk of malnutrition. The degree of impairment in daily functioning is independently related to nutritional status. Therefore, assessment of the nutritional status should be included in the comprehensive assessment of AD patients. The relation between daily functioning, nutritional status and AD warrants further investigation.

    Full Text Available Abstract Background Mass screening for celiac disease (CD as a public health intervention is controversial. Prior to implementation, acceptability to the targeted population should be addressed. We aimed at exploring adolescents' and parents' experiences of having the adolescents' CD detected through mass screening, and their attitudes towards possible future mass screening. Methods All adolescents (n = 145 with screening-detected CD found in a Swedish school-based screening study, and their parents, were invited to this study about one year after diagnosis. In all, 14 focus group discussions were conducted with 31 adolescents and 43 parents. Written narrative was completed by 91 adolescents (63% and 105 parents (72%, and questionnaires returned by 114 parents (79%. Data were analyzed using qualitative content analysis. In addition, narratives and questionnaire data allowed for quantified measures. Results Adolescents and parents described how they agreed to participate "for the good of others," without considering consequences for themselves. However, since the screening also introduced a potential risk of having the disease, the invitation was regarded as "an offer hard to resist." For the majority, receiving the diagnosis was described as "a bolt of lightning," but for some it provided an explanation for previous health problems, and "suddenly everything made sense." Looking back at the screening, the predominant attitude was "feeling grateful for being made aware," but some adolescents and parents also expressed "ambivalent feelings about personal benefits." Among parents, 92% supported future CD screening. The most common opinion among both adolescents and parents was that future CD mass screening should be "a right for everyone" and should be offered as early as possible. However, some argued that it should be "only for sufferers" with symptoms, whereas others were "questioning the benefits" of CD mass screening. Conclusions Although the

    Full Text Available Objectives. We investigated immune phenotypes of HIV+ patients who present late, considering late presenters (LPs, CD4+ < 350/μL and/or AIDS, advanced HIV disease (AHD, CD4+ < 200/μL and/or AIDS, and AIDS presenters (AIDS-defining condition at presentation, independently from CD4+. Methods. Patients newly diagnosed with HIV at our clinic between 2007–2011 were enrolled. Mann-Whitney/Chi-squared tests and logistic regression were used for statistics. Results. 275 patients were newly diagnosed with HIV between January/2007–March/2011. 130 (47% were LPs, 79 (29% showed AHD, and 49 (18% were AIDS presenters. LP, AHD, and AIDS presenters were older and more frequently heterosexuals. Higher CD8+%, lower CD127+CD4+%, higher CD95+CD8+%, CD38+CD8+%, and CD45R0+CD38+CD8+% characterized LP/AHD/AIDS presentation. In multivariate analysis, older age, heterosexuality, higher CD8+%, and lower CD127+CD4+% were confirmed associated with LP/AHD. Lower CD4+ and higher CD38+CD8+% resulted independently associated with AIDS presentation. Conclusions. CD127 downregulation and immune activation characterize HIV+ patients presenting late and would be studied as additional markers of late presentation.

    Background and Purpose Relatively little is known about the natural evolution of physical activity-related participation restrictions associated with Parkinson disease (PD). We examined this issue prospectively using continuous monitoring technology to capture the free-living ambulatory activity of persons living with PD engaging in life situations. We specifically sought (1) to explore natural, long-term changes in daily ambulatory activity, and (2) to compare the responsiveness of ambulatory activity parameters to clinical measures of gait and disease severity. Methods Thirty-three persons with PD participated (Hoehn and Yahr range of 1–3). Participants wore a step activity monitor for up to 7 days at baseline and again at 1-year follow-up. Mean daily values were calculated for parameters indicative of amount, intensity, frequency, and duration of ambulatory activity. Clinical measures included the Unified Parkinson Disease Rating Scale, the 6-Minute Walk, and Maximal Gait Speed. Parametric tests for paired samples were used to investigate changes in ambulatory activity parameters and clinical measures. Results Participants had significant declines in the amount and intensity of daily ambulatory activity but not in its frequency and duration (p < 0.007). Declines occurred in the absence of changes in clinical measures of gait or disease severity. The greatest 1-year decline occurred in the number of daily minutes participants spent engaging in at least moderate-intensity ambulatory activity. Conclusion Continuous monitoring of ambulatory activity beyond mere step counts may serve as a distinct and important means of quantifying declining ambulatory behavior associated with disease progression or improved ambulatory behavior resulting from rehabilitation, medical, and / or surgical interventions in persons with PD.

    Full Text Available Many studies include oral HIV-related endpoints that may be diagnosed by non-oral-health specialists (non-OHS like nurses or physicians. Our objective was to assess the accuracy of clinical diagnoses of HIV-related oral lesions made by non-OHS compared to diagnoses made by OHS.A5254, a cross-sectional study conducted by the Oral HIV/AIDS Research Alliance within the AIDS Clinical Trial Group, enrolled HIV-1-infected adults participants from six clinical trial units (CTU in the US (San Francisco, New York, Chapel Hill, Cleveland, Atlanta and Haiti. CTU examiners (non-OHS received standardized training on how to perform an oral examination and make clinical diagnoses of specific oral disease endpoints. Diagnoses by calibrated non-OHS were compared to those made by calibrated OHS, and sensitivity and specificity computed.Among 324 participants, the majority were black (73%, men (66%, and the median CD4+ cell count 138 cells/mm(3. The overall frequency of oral mucosal disease diagnosed by OHS was 43% in US sites, and 90% in Haiti. Oral candidiasis (OC was detected in 153 (47% by OHS, with erythematous candidiasis (EC the most common type (39% followed by pseudomembranous candidiasis (PC; 26%. The highest prevalence of OC (79% was among participants in Haiti, and among those with CD4+ cell count ≤ 200 cells/mm(3 and HIV-1 RNA > 1000 copies/mL (71%.

    Many studies include oral HIV-related endpoints that may be diagnosed by non-oral-health specialists (non-OHS) like nurses or physicians. Our objective was to assess the accuracy of clinical diagnoses of HIV-related oral lesions made by non-OHS compared to diagnoses made by OHS. A5254, a cross-sectional study conducted by the Oral HIV/AIDS Research Alliance within the AIDS Clinical Trial Group, enrolled HIV-1-infected adults participants from six clinical trial units (CTU) in the US (San Francisco, New York, Chapel Hill, Cleveland, Atlanta) and Haiti. CTU examiners (non-OHS) received standardized training on how to perform an oral examination and make clinical diagnoses of specific oral disease endpoints. Diagnoses by calibrated non-OHS were compared to those made by calibrated OHS, and sensitivity and specificity computed. Among 324 participants, the majority were black (73%), men (66%), and the median CD4+ cell count 138 cells/mm(3). The overall frequency of oral mucosal disease diagnosed by OHS was 43% in US sites, and 90% in Haiti. Oral candidiasis (OC) was detected in 153 (47%) by OHS, with erythematous candidiasis (EC) the most common type (39%) followed by pseudomembranous candidiasis (PC; 26%). The highest prevalence of OC (79%) was among participants in Haiti, and among those with CD4+ cell count ≤ 200 cells/mm(3) and HIV-1 RNA > 1000 copies/mL (71%). The sensitivity and specificity of OC diagnoses by non-OHS were 90% and 92% (for EC: 81% and 94%; PC: 82% and 95%). Sensitivity and specificity were also high for KS (87% and 94%, respectively), but sensitivity was oral warts in all sites combined. The Candida culture confirmation of OC clinical diagnoses (as defined by ≥ 1 colony forming unit per mL of oral/throat rinse) was ≥ 93% for both PC and EC. Trained non-OHS showed high accuracy of clinical diagnoses of OC in comparison with OHS, suggesting their usefulness in studies in resource-poor settings, but detection of less common lesions may require

    Inflammatory bowel disease (IBD) is a chronic relapsing disease characterized by activation of the mucosal immune system and inflammation of the gastrointestinal tract. Management of IBD places a significant burden on the health care system because of the complexity of treatment, variability in patient outcomes, and chronic nature of the disease.  To investigate the American Gastroenterological Association (AGA) and Crohn's and Colitis Foundation of America's (CCFA) quality measurement sets in a sample of IBD patients. Fourteen quality measures were restated for application to a claims database and calculated using Optum Clinformatics DataMart database. Selected measures were calculated over calendar year 2011. Performance measures ranged from 0.4% for AGA measure 9, prophylaxis for venous thromboembolism, to 66.9% for AGA measure 8, testing for Clostridium difficile. CCFA outcome measures ranged from 0.6% qualifying for CCFA O10, report of fecal incontinence, to 32.9% for CCFA O1, prednisone usage. In addition to Clostridium difficile testing, the use of appropriate corticosteroid-sparing therapy (51.1%) and testing for latent tuberculosis before initiating anti-tumor necrosis factor therapy (45.0%) were the highest achieved measures. This is the first examination of IBD quality measures using administrative claims. Rates of achievement across measures were variable and likely affected by the ability to calculate certain measures with claims data. Future studies should further examine measurement of IBD quality indicators in claims data to assess the validity of claims-based analyses and to ascertain whether measure attainment translates into better overall health or IBD-related outcomes.

    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

  2. Inferring pathway activity toward precise disease classification.

    Full Text Available The advent of microarray technology has made it possible to classify disease states based on gene expression profiles of patients. Typically, marker genes are selected by measuring the power of their expression profiles to discriminate among patients of different disease states. However, expression-based classification can be challenging in complex diseases due to factors such as cellular heterogeneity within a tissue sample and genetic heterogeneity across patients. A promising technique for coping with these challenges is to incorporate pathway information into the disease classification procedure in order to classify disease based on the activity of entire signaling pathways or protein complexes rather than on the expression levels of individual genes or proteins. We propose a new classification method based on pathway activities inferred for each patient. For each pathway, an activity level is summarized from the gene expression levels of its condition-responsive genes (CORGs, defined as the subset of genes in the pathway whose combined expression delivers optimal discriminative power for the disease phenotype. We show that classifiers using pathway activity achieve better performance than classifiers based on individual gene expression, for both simple and complex case-control studies including differentiation of perturbed from non-perturbed cells and subtyping of several different kinds of cancer. Moreover, the new method outperforms several previous approaches that use a static (i.e., non-conditional definition of pathways. Within a pathway, the identified CORGs may facilitate the development of better diagnostic markers and the discovery of core alterations in human disease.

    To retrospectively compare the accuracy of axial and coronal planes of CT enterography for detection of pathologic findings of Crohn disease. 168 patients who were suspected of having Crohn disease underwent CT enterography. 66 patients who were diagnosed Crohn disease were retrospectively evaluated (endoscopic biopsy of terminal ileum: 12 patients, segmental resection of small bowel: 6 patients, diagnosed based on a combination of clinical, histopathological and imaging findings: 48 patients). 2 radiologists reviewed axial planes of CT enterography and one month later reviewed coronal planes. CT enterography findings of active phase, chronic phase and complications of Crohn disease were evaluated and then compared with axial and coronal planes by using chi-square test. Mucosal hyperenhancement, wall thickening, and mesenteric fat stranding were more detected on axial planes, which were CT findings of active Crohn disease. Pseudosacculation, fibrotic strictures, fistulas, abscesses were more detected on coronal planes, which were CT findings of chronic Crohn disease or complications. In particular, pseudosacculation and fibrotic strictures were significantly more detected on coronal planes. When evaluating CT enterography in Crohn disease, coronal planes provide more useful diagnostic information of pseudosacculation and fibrotic strictures.

However, studies examining their effectiveness in routine practice among diverse patient populations are lacking. Among a cohort of new users of 6MP/AZA, we described treatment patterns and changes in subsequent therapy. Methods: Using the Truven Health Analytics databases, we identified all individuals diagnosed with CD and initiating 6-MP/AZA monotherapy from 2001–2008 (n=3,657. We estimated the proportion of CD patients remaining on 6-MP/AZA monotherapy, using Kaplan–Meier methods, and identified predictors of treatment noncontinuation, using multivariable Cox regression. Among the “noncontinuers,” we described subsequent patterns of maintenance therapy and summarized the diagnosis and procedure codes and prescription drug claims preceding treatment discontinuation. Results: The 1-year 6-MP/AZA treatment continuation rate was 42%. Children (age ≤18 years and individuals with no prior anti-tumor necrosis factor (TNF use were more likely to continue 6-MP/AZA, while those dispensed more (>4 outpatient prescriptions for any drug before initiation of 6-MP/AZA were less likely to continue maintenance treatment. Overall, 1,128 (39% and 105 (4% individuals experienced a clinical event potentially indicating active disease or 6-MP/AZA-intolerance prior to discontinuation, respectively. Most patients discontinued therapy; among the remaining patients who failed to continue 6-MP/AZA, most augmented with an anti-TNF. Conclusion: Most patients initiating 6-MP

    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

    We analyzed parasitic diseases diagnosed by tissue biopsy specimens at KyungHee Medical Center (KMC) from 1984 to 2005. The total number of parasite infection cases was 150 (0.07%) out of the total 211,859 biopsy specimens submitted for histopathological examinations. They consisted of 62 cysticercosis, 23 sparganosis, 16 paragonimiasis, 15 amebiasis, 11 anisakiasis, 11 clonorchiasis, 3 ascariasis, 2 scabies, 2 enterobiasis, 2 trichuriasis, 1 leishmaniasis, 1 taeniasis, and 1 thelaziasis. Out of 62 cysticercosis cases, 55 were detected in subcutaneous tissues or the central nerve system. Eighteen out of 23 sparganosis cases were involved in muscular and subcutaneous tissues. In most anisakiasis cases, the involved organ was the stomach. The lung and the pleura were the most common site of paragonimiasis. The incidence of parasitic diseases during the first 5 years (1984-1988) was the highest of all observed periods. After 1989, similar incidences were shown throughout the period. Whereas cysticercosis was diagnosed in 34 cases during 1984-1988, no case has been diagnosed since 2000. In the case of sparganosis, the chronological incidence was almost uniform throughout the period 1984-2005. Paragonimiasis showed a similar tendency to cysticercosis. In gender and age distribution of parasitic diseases, men showed higher incidence rates than females, and the age groups of the 40s or older indicated higher infection frequencies than other age groups. Therefore, these results are a significant report to appear the tendency of human parasitic disease diagnosed by tissue biopsy in association with parasitosis at KMC in Seoul.

    Full Text Available BACKGROUND Rheumatoid arthritis is a well-known chronic inflammatory autoimmune disease which affects multiple joints usually in a symmetrical manner. Apart from the joints, RA can affect numerous other systems of the body like cardiovascular, neurological, haematological, skin, blood vessels, etc. The most common cause of death of RA patients has been found to be cardiovascular disease due to coronary artery disease. Chronic inflammatory state and dyslipidaemia 1,2 have been proposed as the reasons for accelerated atherosclerosis in RA. There are very few studies in India about lipid profile abnormality in rheumatoid arthritis and its relationship with the severity of the disease in RA patients. There is lacuna of knowledge about this aspect of disease in Indian patients. This study aims to address this issue. AIM To study lipid profile abnormalities and its relationship with the severity and number of ACR criteria of Rheumatoid Arthritis. MATERIALS AND METHODS This cross-sectional study was conducted from August 2009 – August 2011, patients fulfilling the American College of Rheumatology 1987 criteria for Rheumatoid Arthritis., 3 newly diagnosed and patients on treatment for Rheumatoid Arthritis are taken into consideration. Dyslipidaemia defined using the high cut-off values of National Cholesterol Education ProgrammeAdult Treatment Panel. Disease Activity Score DAS-28(4 was employed to calculate the disease activity. For all patients after an overnight fasting blood samples were collected and serum was separated and Fasting Lipid Profile was done enzymatically using standardised Flex® reagent cartridges for Total Cholesterol, High Density Lipoproteins, Low Density Lipoproteins and Triglycerides. RA factor was done using Latex Agglutination Test. ESR for assessing DAS 28 was done using Wintrobe’s method.

    Chemokines and cytokines are key signaling molecules that orchestrate the trafficking of immune cells, direct them to sites of tissue injury and inflammation and modulate their states of activation and effector cell function. We have measured, using a multiplex-based approach, the levels of 58 immune mediators and 7 acute phase markers in sera derived from of a cohort of patients diagnosed with acute Lyme disease and matched controls. This analysis identified a cytokine signature associated with the early stages of infection and allowed us to identify two subsets (mediator-high and mediator-low) of acute Lyme patients with distinct cytokine signatures that also differed significantly (pLyme disease (p = 0.01) and the decrease correlates with chemokine levels (p = 0.0375). The levels of CXCL9/10 did not relate to the size or number of skin lesions but elevated levels of serum CXCL9/CXCL10 were associated with elevated liver enzymes levels. Collectively these results indicate that the levels of serum chemokines and the levels of expression of their respective chemokine receptors on T cell subsets may prove to be informative biomarkers for Lyme disease and related to specific disease manifestations.

    To conduct a one year follow up study of patients seen in a combined rapid access chest pain, arrhythmia and heart failure clinic. Local general practitioners, accident and emergency department clinicians and other hospital clinicians were invited to refer patients with a new presentation of chest pain, palpitations and suspected cardiac-induced breathlessness to the rapid access cardiology clinics at Charing Cross Hospital, London, on a one-stop, no appointment basis. Consent to be followed up by a postal questionnaire one year later was sought from all patients attending between 1 November 2002 and 31 October 2003. 1223 patients were seen in the 12 month study period. 940 (77%) consented to one year follow up. 216 (23%) patients had a diagnosis of definite cardiac, 621 (66%) of not cardiac and 103 of possible cardiac disease (11%). 98% of patients diagnosed "not cardiac" did not receive a diagnosis of cardiac disease over the following 12 months. Of patients with diagnosed definite cardiac disease, one year cardiac mortality was 7 of 216 (3%), compared with an age- and sex-matched expected cardiac mortality of 0.9% (standardised mortality ratio 3.5, 95% confidence interval (CI) 1.4 to 7.2). For patients with an initial diagnosis of possible or not cardiac disease, cardiac mortality at one year was 0.3% compared with an expected cardiac mortality of 0.4% (standardised mortality ratio 0.8, 95% CI 0.1 to 2.8). A rapid access cardiology clinic accurately diagnoses and risk stratifies patients into those with cardiac disease at high risk of cardiac death and those without significant cardiac disease.

    Purpose: Major arterial hemorrhage is an uncommon but serious complication of pancreatitis with high morbidity and mortality. Digital subtraction angiography (DSA) has long been the gold standard for the detection of a visceral artery pseudoaneurysm or for the site of active bleeding in patients with pancreatitis. Multi-section CT angiography is a minimally invasive technique which can provide high-resolution and high-contrast images of the arterial lumen and wall, with a much lower risk of complication and morbidity compared to DSA. The aim of this study was to determine the accuracy of multi-section CT angiography for the diagnosis of arterial complications of inflammatory pancreatitic disease. Materials and methods: A retrospective analysis of all patients undergoing visceral angiography for major bleeding as a complication of pancreatitis between 1998 and 2004 was performed. Twenty-nine studies in 25 patients (20 males, 5 females) with a mean age of 50.9 years (range 11-67 years) were identified where multi-section CT angiography was performed in the 24 h preceding the digital subtraction angiogram. Results: Digital subtraction angiography detected a pseudoaneurysm or contrast extravasation in 19 studies and no bleeding was demonstrated in 9 studies. CT angiography correctly identified the site and type of bleeding in 18 of the 19 positive studies. CT angiography detected extravasation of contrast in one study that was not demonstrated on digital subtraction angiography. The sensitivity and specificity for multi-section CT angiography for the detection of major arterial bleeding on a background of pancreatitis were 0.947 and 0.900, respectively. Conclusion: Multi-section CT angiography is a sensitive and accurate technique for the detection of major arterial hemorrhage in inflammatory pancreatic disease and should be considered as the first investigation in the management of these patients

    This article reviews the diagnostically challenging presentation of mast cell activation disease (MCAD) and current thoughts regarding interactions between microbiota and MCs. A search for all studies on interactions between mast cells, mast cell activation disease, and microbiota published on pubmed.gov and scholar.google.com between 1960 and 2015 was conducted using the search terms mast cell, mastocyte, mastocytosis, mast cell activation, mast cell activation disease, mast cell activation syndrome, microbiome, microbiota. A manual review of the references from identified studies was also conducted. Studies were excluded if they were not accessible electronically or by interlibrary loan. Research increasingly is revealing essential involvement of MCs in normal human biology and in human disease. Via many methods, normal MCs-present sparsely in every tissue-sense their environment and reactively exert influences that, directly and indirectly, locally and remotely, improve health. The dysfunctional MCs of the "iceberg" of MCAD, on the other hand, sense abnormally, react abnormally, activate constitutively, and sometimes (in mastocytosis, the "tip" of the MCAD iceberg) even proliferate neoplastically. MCAD causes chronic multisystem illness generally, but not necessarily, of an inflammatory ± allergic theme and with great variability in behavior among patients and within any patient over time. Furthermore, the range of signals to which MCs respond and react include signals from the body's microbiota, and regardless of whether an MCAD patient has clonal mastocytosis or the bulk of the iceberg now known as MC activation syndrome (also suspected to be clonal but without significant MC proliferation), dysfunctional MCs interact as dysfunctionally with those microbiota as they interact with other human tissues, potentially leading to many adverse consequences. Interactions between microbiota and MCs are complex at baseline. The potential for both pathology and benefit

    Disease activity measured by validated methods has been sparsely examined during and after pregnancy in women with systemic lupus erythematosus (SLE). The aim of this study was to describe the longitudinal course of disease activity during pregnancy and the first year postpartum using the Lupus Activity Index in Pregnancy (LAI-P). RevNatus is a nationwide Norwegian prospective observational register including women diagnosed with inflammatory rheumatic diseases. LAI-P is a modified version of the LAI, with a good ability to assess disease activity in pregnant women with SLE. These indexes were used to assess disease activity at 6 visits (in trimesters 1, 2, and 3, and at 6 weeks, 6 months, and 12 months postpartum). The longitudinal course of disease activity was analyzed using an ordinal logistic mixed model. A total of 757 visits (145 pregnancies) in women with SLE were included in the analysis. More than half (51.6%) of the disease activity scores indicated remission, and only 6.3% indicated moderate disease activity. The model showed a statistically significant and clinically relevant change in disease activity over time, and a higher disease activity 6 and 12 months postpartum compared to the third trimester and 6 weeks postpartum. The majority of women had low or no disease activity at conception and during pregnancy, with higher disease activity at 6 and 12 months after delivery. This points to the importance of tight disease control not only before and during pregnancy but also in the first year postpartum. © 2016, American College of Rheumatology.

    Histologic assessment of mucosal disease activity has been increasingly used in clinical trials of treatment for Crohn's disease. However, the operating properties of the currently existing histologic scoring indices remain unclear. A systematic review was undertaken to evaluate the development and operating characteristics of available histologic disease activity indices in Crohn's disease. Electronic searches of MEDLINE, EMBASE, PubMed, and the Cochrane Library (CENTRAL) databases from inception to 20 July 2016 were supplemented by manual reviews of bibliographies and abstracts submitted to major gastroenterology meetings (Digestive Disease Week, United European Gastroenterology Week, European Crohn's and Colitis Organisation). Any study design (e.g. randomised controlled trial, cohort study, case series) that evaluated a histologic disease activity index in patients with Crohn's disease was considered for inclusion. Study participants included adult patients (> 16 years), diagnosed with Crohn's disease using conventional clinical, radiographic or endoscopic criteria. Two authors independently reviewed the titles and abstracts of the studies identified from the literature search. The full text of potentially relevant citations were reviewed for inclusion and the study investigators were contacted as needed for clarification. Any disagreements regarding study eligibility were resolved by discussion and consensus with a third author.Two authors independently extracted and recorded data using a standard form. The following data were recorded from each eligible study: number of patients enrolled; number of patients per treatment arm; patient characteristics: age and gender distribution; description of histologic disease activity index utilized; and outcomes such as content validity, construct validity, criterion validity, responsiveness, intra-rater reliability, inter-rater reliability, and feasibility.

    Recently, the clinical pemphigus disease activity indexes of Pemphigus Disease Area Index (PDAI), Autoimmune Bullous Skin Disorder Intensity Score (ABSIS), and Pemphigus Vulgaris Activity Score (PVAS) were validated to correlate with physician global assessment. The antidesmoglein (anti-Dsg) autoantibodies are known to correlate mostly with pemphigus disease activity. The correlation between these indexes and anti-Dsg1 and anti-Dsg3 enzyme-linked immunosorbent assay values has not been previously evaluated. To evaluate the PDAI, ABSIS, and PVAS in a large number of patients with pemphigus vulgaris and to compare the interrater reliability of these indexes and the convergent validity according to anti-Dsg values. A cross-sectional study was performed in 2012 in a referral university center for autoimmune bullous diseases. One hundred patients with confirmed diagnoses of pemphigus vulgaris and clinical pemphigus lesions (mean [SD] age, 43.3 [1.7] years; age range, 14-77 years; female-male ratio, 1:3) were studied. Three dermatologists familiar with immunobullous diseases and the indexes rated the patients. All 100 patients were evaluated with the PDAI, ABSIS, and PVAS. Three dermatologists independently rated all 3 indexes for each of the patients on the same day. Serum anti-Dsg1 and anti-Dsg3 enzyme-linked immunosorbent assay values were measured simultaneously. Analyses of interrater reliabilities, convergent validities according to anti-Dsg titers, correlation between the distribution and types of lesions with disease activity, predictors of higher titers of antibody (multiple regression analysis), and cutoff values of measures for 2 titers of anti-Dsg with optimal area under the curve, sensitivity, and specificity were performed. The interrater reliabilities were highest for the PDAI, followed by the ABSIS and the PVAS (intraclass correlation coefficients of 0.98 [95% CI, 0.97-0.98], 0.97 [95% CI, 0.96-0.98], and 0.93 [95% CI, 0.90-0.95], respectively).

    Patients with Graves' disease were studied for two years during and after a twelve-month course of treatment. Disease activity was determined by repeated measurements of thyroidal uptake of [/sup 99m/Tc]pertechnetate during tri-iodothyronine administration. These in-vivo measurements of thyroid stimulation were compared with the results of in-vitro assays of Graves, immunoglobulin (TSH binding inhibitory activity--TBIA). There was no correlation between the thyroid uptake and TBIA on diagnosis. Pertechnetate uptake and TBIA both declined during the twelve months of antithyroid therapy. TBIA was detectable in sera from 19 of the 27 patients at diagnosis; in 11 of these 19 patients there was a good correlation (p less than 0.05) throughout the course of their disease between the laboratory assay of the Graves, immunoglobulin and the thyroid uptake. Probability of recurrence can be assessed but sustained remission of Graves' disease after treatment cannot be predicted from either measurement alone or in combination

    Music therapy (MT) is an unconventional, multisensorial therapy poorly assessed in medical care but widely used to different ends in a variety of settings. MT has two branches: active and passive. In active MT the utilisation of instruments is structured to correspond to all sensory organs so as to obtain suitable motor and emotional responses. We conducted a prospective study to evaluate the effects of MT in the neurorehabilitation of patients with Parkinson's Disease (PD), a common degenerative disorder involving movement and emotional impairment. Sixteen PD patients took part in 13 weekly sessions of MT each lasting 2 hours. At the beginning and at the end of the session, every 2 weeks, the patients were evaluated by a neurologist, who assessed PD severity with UPDRS, emotional functions with Happiness Measures (HM) and quality of life using the Parkinson's Disease Quality of Life Questionnaire (PDQL). After every session a significant improvement in motor function, particularly in relation to hypokinesia, was observed both in the overall and in the pre-post session evaluations. HM, UPDRS-ADL and PDQL changes confirmed an improving effect of MT on emotional functions, activities of daily living and quality of life. In conclusion, active MT, operating at a multisensorial level, stimulates motor, affective and behavioural functions. Finally, we propose active MT as new method to include in PD rehabilitation programmes. This article describes the methods adopted during MT sessions with PD patients.

    Neurologists and psychiatrists frequently encounter patients whose central and/or peripheral neurologic and/or psychiatric symptoms (NPS) are accompanied by other symptoms for which investigation finds no unifying cause and for which empiric therapy often provides little to no benefit. Systemic mast cell activation disease (MCAD) has rarely been considered in the differential diagnosis in such situations. Traditionally, MCAD has been considered as just one rare (neoplastic) disease, mastocytosis, generally focusing on the mast cell (MC) mediators tryptase and histamine and the suggestive, blatant symptoms of flushing and anaphylaxis. Recently another form of MCAD, MC activation syndrome (MC), has been recognized, featuring inappropriate MC activation with little to no neoplasia and likely much more heterogeneously clonal and far more prevalent than mastocytosis. There also has developed greater appreciation for the truly very large menagerie of MC mediators and their complex patterns of release, engendering complex, nebulous presentations of chronic and acute illness best characterized as multisystem polymorbidity of generally inflammatory ± allergic themes--including very wide arrays of central and peripheral NPS. Significantly helpful treatment--including for neuropsychiatric issues--usually can be identified once MCAD is accurately diagnosed. We describe MCAD's pathogenesis, presentation (focusing on NPS), and therapy, especially vis-à-vis neuropsychotropes. Since MCAD patients often present NPS, neurologists and psychiatrists have the opportunity, in recognizing the diagnostic possibility of MCAD, to short-circuit the often decades-long delay in establishing the correct diagnosis required to identify optimal therapy.

    Hyperglycemia, insulin resistance, dislipidemia, oxidative stress and inflammation are well-documented risk factors for subclinical atherosclerosis. Dipeptidyl peptidase-4(DPP4) is a newly identified adipokine related to these risk factors. Hence, we aimed to investigate the association between plasma DPP4 activities and subclinical atherosclerosis in type 2 diabetes. A total of 985 newly diagnosed type 2 diabetic subjects were studied. Plasma DPP4 activity, mannose 6-phosphate receptor (M6P-R), oxidative stress parameters, inflammatory markers and common carotid artery Intima-Media Thickness (c-IMT) were measured in all participants. Participants in the highest quartile of DPP4 activity had higher HbA1c, homeostatic model assessment of insulin resistance(HOMA-IR), triglyceride, low-density lipoprotein cholesterol(LDL-C), oxidized LDL, nitrotyrosine, 8-iso-PGF2a, interleukin-6 (IL-6), high-sensitivity C-reactive protein (hs-CRP), M6P-R, c-IMT compared with participants in the lowest quartile (all P atherosclerosis risk was significantly higher (OR 4.97; 95% CI 3.03-8.17) than in the lowest quartile. This association remained strong (2.17; 1.21-3.89) after further controlling for HbA1c, HOMA-IR, triglyceride, oxidized LDL, nitrotyrosine, and IL-6. This study shows that increased DPP4 activities are positively and independently associated with subclinical atherosclerosis in type 2 diabetes. Our findings suggest of potential role of DPP4 in the pathogenesis of subclinical atherosclerosis and in the prevention and management of this disease. Copyright © 2015 Elsevier Ireland Ltd.

    Little is known about using electronic medical records to identify patients with chronic obstructive pulmonary disease to improve quality of care. Our objective was to develop electronic medical record algorithms that can accurately identify patients with obstructive pulmonary disease. A retrospective chart abstraction study was conducted on data from the Electronic Medical Record Administrative data Linked Database (EMRALD ® ) housed at the Institute for Clinical Evaluative Sciences. Abstracted charts provided the reference standard based on available physician-diagnoses, chronic obstructive pulmonary disease-specific medications, smoking history and pulmonary function testing. Chronic obstructive pulmonary disease electronic medical record algorithms using combinations of terminology in the cumulative patient profile (CPP; problem list/past medical history), physician billing codes (chronic bronchitis/emphysema/other chronic obstructive pulmonary disease), and prescriptions, were tested against the reference standard. Sensitivity, specificity, and positive/negative predictive values (PPV/NPV) were calculated. There were 364 patients with chronic obstructive pulmonary disease identified in a 5889 randomly sampled cohort aged ≥ 35 years (prevalence = 6.2%). The electronic medical record algorithm consisting of ≥ 3 physician billing codes for chronic obstructive pulmonary disease per year; documentation in the CPP; tiotropium prescription; or ipratropium (or its formulations) prescription and a chronic obstructive pulmonary disease billing code had sensitivity of 76.9% (95% CI:72.2-81.2), specificity of 99.7% (99.5-99.8), PPV of 93.6% (90.3-96.1), and NPV of 98.5% (98.1-98.8). Electronic medical record algorithms can accurately identify patients with chronic obstructive pulmonary disease in primary care records. They can be used to enable further studies in practice patterns and chronic obstructive pulmonary disease management in primary care. NOVEL

    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.

    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.

    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 utility of perfusion-weighted imaging in multiple sclerosis (MS) is not well investigated. The purpose of this study was to compare baseline normalized perfusion measures in subgroups of newly diagnosed MS patients. We wanted to test the hypothesis that this method can differentiate between groups defined according to disease severity and disease activity at 1 year follow-up. Baseline magnetic resonance imaging (MRI) including a dynamic susceptibility contrast perfusion sequence was performed on a 1.5-T scanner in 66 patients newly diagnosed with relapsing-remitting MS. From the baseline MRI, cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT) maps were generated. Normalized (n) perfusion values were calculated by dividing each perfusion parameter obtained in white matter lesions by the same parameter obtained in normal-appearing white matter. Neurological examination was performed at baseline and at follow-up approximately 1 year later to establish the multiple sclerosis severity score (MSSS) and evidence of disease activity (EDA). Baseline normalized mean transit time (nMTT) was lower in patients with MSSS >3.79 (p = 0.016), in patients with EDA (p = 0.041), and in patients with both MSSS >3.79 and EDA (p = 0.032) at 1-year follow-up. Baseline normalized cerebral blood flow and normalized cerebral blood volume did not differ between these groups. Lower baseline nMTT was associated with higher disease severity and with presence of disease activity 1 year later in newly diagnosed MS patients. Further longitudinal studies are needed to confirm whether baseline-normalized perfusion measures can differentiate between disease severity and disease activity subgroups over time. (orig.)

    Immigrant Latino workers represent an expanding workforce in rural areas of the USA, where their employment is concentrated in occupations such as poultry processing that entail chemical, infectious, and mechanical skin exposures. Occupation-related skin illnesses in this vulnerable population are not well characterized. This study was designed to describe the prevalences of skin diseases among immigrant Latino poultry processors and other manual workers in North Carolina. Community-based sampling was used to recruit 742 immigrant Latino workers, 518 of whom underwent a physical examination supervised by a board-certified dermatologist. The presence or absence of skin disease on the face, neck, arms, hands, and feet was recorded. Workers ranged in age from 18 years to 68 years. Slightly over half of the sample were male (52.6%). Poultry workers represented 55.8% of the study sample. Infectious skin diseases were the most common diagnosis, present in 52.3% of workers. Inflammatory skin diseases were present in 28.2% and pigmentary disorders in 21.8% of workers. The most common skin conditions were tinea pedis (37.6%), onychomycosis (31.9%), scars (13.7%), acne (11.8%), and melasma (9.3%). Age, sex, first language, and work as a poultry processor accounted in part for the prevalence of these diseases. Several skin diseases are highly prevalent in immigrant Latino workers and may relate to work environment. These may impair the quality of life of these workers and predispose them to further illness. © 2013 The International Society of Dermatology.

    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 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 breast cancer, with a higher

    Information concerning inherited metabolic diseases in China is scarce. We investigated the prevalence and age distributions of amino acid, organic acid, and fatty acid oxidation disorders in Chinese patients. Blood levels of amino acids and acylcarnitines (tandem mass spectrometry) were measured in 18,303 patients with suspected inherited metabolic diseases. Diagnosis was based on clinical features, blood levels of amino acids or acylcarnitines, urinary organic acid levels (gas chromatography-mass spectrometry), and (in some) gene mutation tests. Inherited metabolic diseases were confirmed in 1,135 patients (739 males, 396 females). Median age was 12 months (1 day to 59 years). There were 28 diseases: 12 amino acid disorders (580 patients, 51.1%), with hyperphenylalaninemia (HPA) being the most common; nine organic acidemias (408 patients, 35.9%), with methylmalonic acidemia (MMA) as the most common; and seven fatty acid oxidation defects (147 patients, 13.0%), with multiple acyl-coenzyme A dehydrogenase deficiency (MADD) being the most common. Onset was mainly at 1-6 months for citrin deficiency, 0-6 months for MMA, and in newborns for ornithine transcarbamylase deficiency (OTCD). HPA was common in patients aged 1-3 years, and MADD was common in patients >18 years. In China, HPA, citrin deficiency, MMA, and MADD are the most common inherited disorders, particularly in newborns/infants. © 2014 Wiley Periodicals, Inc.

    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

    The appearance of early Kienböck disease on radiographs and magnetic resonance imaging (MRI) may be difficult to distinguish from other conditions that affect the lunate. We aimed to assess the interobserver agreement in the diagnosis of early Kienböck disease when evaluated on different imaging modalities. Forty-three hand surgeon members of the Science of Variation Group were randomized to evaluate radiographs and 35 hand surgeons to evaluate radiographs and MRI scans of 26 patients for the presence of Kienböck disease, the lunate type, and the ulnar variance. We used Fleiss' kappa analysis to assess the interobserver agreement for categorical variables and compared the κ values between the 2 groups. We found that agreement on the diagnosis of early Kienböck disease was fair (κ, 0.36) among observers who evaluated radiographs alone and moderate (κ, 0.58) among observers who evaluated MRI scans in addition to radiographs, and that the difference in κ values was not statistically significant ( P = .057). Agreement did not differ between observers based on imaging modality with regard to the assessment of the lunate type ( P = .75) and ulnar variance ( P = .15). We found, with the numbers evaluated, a notable but nonsignificant difference in agreement in favor of observers who evaluated MRI scans in addition to radiographs compared with radiographs alone. Surgeons should be aware that the diagnosis of Kienböck disease in the precollapse stages is not well defined, as evidenced by the substantial interobserver variability.

    Among US adults, utilization of pharmacotherapy for attention-deficit hyperactivity disorder (ADHD) has increased more than ninefold since 1995-1996. Potential contraindications to ADHD pharmacotherapy include serious cardiovascular disease (CVD) and, for stimulants, addictions and bipolar disorder (BPD). To assess the prevalence of potential contraindications among adults treated with ADHD pharmacotherapy. A retrospective cohort analysis was performed using the Truven Health MarketScan ® database. Subjects filled ≥ 1 prescription for atomoxetine or ≥ 1 stimulant in 2014-2015, were aged 18-64 years, commercially insured throughout observation, and diagnosed with ADHD on two or more medical claims. Diagnoses and medical procedures were measured in the 12 months prior to pharmacotherapy initiation. Metrics included serious CVD (cardiomegaly, cardiomyopathy, cerebrovascular occlusion, congestive heart failure, myocardial infarction, pacemaker, or valvular disorder) and any CVD (serious CVD, other atherosclerotic CVD, arrhythmia, congenital heart anomaly, or hypertensive heart disease). Rates of substance addiction or abuse were measured in a range to address nonspecific diagnostic coding. Only 2.0% of treated adults (n = 91,588) had one or more diagnosis indicating serious CVD. CVD prevalence increased monotonically with age. Of patients aged 55-64 years (n = 5,237), 7.2% had serious CVD; 15.9% had any CVD; and 1.9% had been hospitalized with one or more CVD. Of patients treated with stimulants (n = 87,167), 11.3-18.5% were diagnosed with addiction/abuse and 4.1% with BPD. CVD prevalence is generally low among adults using ADHD medication but increases with age. Although difficult to estimate precisely, the rate of addiction/abuse among stimulant-treated patients appears unexpectedly high. Further research should assess cardiovascular events and other potential harms associated with contraindicated use in high-risk adults.

    There is no formal association between premature coronary artery disease (CAD) and Prader-Willi syndrome despite its association with hyperlipidaemia, diabetes mellitus and hypertension. A 36-year-old man with Prader-Willi syndrome presented with acute breathlessness. Inflammatory markers were borderline elevated and chest radiography demonstrated unilateral diffuse alveolar shadowing. Bronchopneumonia was diagnosed and despite treatment with multiple courses of antimicrobial therapy, there was minimal symptomatic and radiographical improvement. A diagnosis of unilateral pulmonary oedema was suspected. Echocardiography was non-diagnostic due to body habitus and coronary angiography was deemed inappropriate due to uncertainty in diagnosis, invasiveness and pre-existing chronic kidney disease. Therefore, cardiac magnetic resonance was performed, confirming severe triple-vessel CAD. This case demonstrates a presentation of heart failure with unilateral chest radiograph changes in a young patient with Prader-Willi syndrome and severe premature CAD detected by multiparametric cardiac magnetic resonance imaging.

    Full Text Available Celiac disease (CD is a chronic small intestinal enteropathy triggered by gluten in genetically predisposed individuals. The susceptibility is strongly associated with certain human leukocyte antigen (HLA-genes, but efforts are being made in trying to find non-HLA genes that are predictive for the disease. The criteria for diagnosing CD were previously based primarily on histologic evaluation of small intestinal biopsies, but nowadays are often based only on blood tests and symptoms. In this context, we elucidated the accuracy of three diagnostic indicators for CD, alone or in combination. Genetic analyses of HLA-type and nine single nucleotide polymorphisms (SNPs known to be associated with CD were performed in 177 children previously investigated for the suspicion of CD. CD was confirmed in 109 children, while 68 were considered non-celiacs. The antibodies and urinary nitrite/nitrate concentrations of all of them were measured. The combinations of all the variables used in the study would classify 93% of the study population in the correct diagnostic group. The single best predictors were antibodies (i.e., anti-endomysium immunoglobulin A (IgA (EMA and transglutaminase IgA (TGA, followed by HLA-type and nitric oxide (NO-metabolites. The nine SNPs used did not contribute to the right diagnoses. Although our control group consisted of children with mostly gastrointestinal symptoms, the presented methodology predicted a correct classification in more than 90% of the cases.

    Full Text Available Introduction Endothelial dysfunction is an early event in the progression of atherosclerosis, and it appears in pathologies such as dyslipidemias. Certain pro-inflammatory enzymes are associated negatively with high-density lipoproteins (HDL and positively with low-density lipoproteins (LDL. Calculating the atherogenic index greatly complements the study of these diseases. Lipid alterations have a high prevalence in Ecuadorian and Latin American populations. Better knowledge of which lipid alteration is the most prevalent would bring more attention to the subject, leading to early treatment. The goal of this study is to describe the complete lipid profile alterations in patients recently diagnosed with ischemic heart disease and find which of these is the most prevalent. Methods We designed a cross-sectional, descriptive study that included patients from the Cardiology Service of the “Hospital Luis Vernaza” who presented with the first episode of ischemic heart disease between January 2012 and 2013. There were 220 patients with that diagnosis. One-hundred and thirty-one (131 were excluded because they did not meet inclusion criteria. The final sample comprised 89 patients. Results We found 41 (46.06% patients with low HDL levels, 49 (55.05% with high LDL levels, 28 (31.46% with high triglycerides, 24 (26.96% with high cholesterol levels, 25 (28.08% with high VLDL levels, 26 (29.21% had values over 5 in the Castelli index, and 32 (35.95% had LDL/HDL values higher than 3. Discussion It is of great importance to have a complete lipid profile from patients recently diagnosed with ischemic heart disease in order to work on secondary prevention. The most prevalent alteration found in our study was high LDL levels. The percentage of patients with low HDL was similar to other Latin American populations. More studies are needed to gain a more accurate idea of the status of the general population in this regard.

    Objective: To evaluate the efficacy of 99 Tc m labelled human IgG ( 99 Tc m -HIgG) as the tracer for early detection of bowel involvement and disease activity in Crohn disease and ulcerative colitis. Methods: The authors have studied 22 cases with known ulcerative colitis and 19 cases with diagnosed Crohn disease. Twenty-eight were men and 13 were women aged (35 +- 15) years. 370-740 MBq (1 mg) of 99 Tc m -HIgG was injected intravenously. The whole-body scan (ANT and POST) were obtained after 1,2,4,6 h delays or 24 h if necessary. Whenever abnormal areas were found, multiple spot views were required. Results: Twenty-one out of 22 ulcerative colitis patients were found positive. The positive rate was 95%. Seventeen out of 19 Crohn disease patients were positive and the positive rate was 89%. All the negative cases were not with active disease. With respect to the activity of the disease, the positive rate of 99 Tc m -HIgG scan in ulcerative colitis was 100% equal to the endoscopy. While in Crohn disease the positive rate with 99 Tc m -HIgG, endoscopy and X-ray were 100, 30% and 94% respectively. In both diseases while it was in the remission stage, the scans were normal. Conclusions: 1) 99 Tc m -HIgG is a sensitive and reliable method for detecting the presence and extent of inflammatory bowel disease. 2) It can provide clinically useful assessment of disease activity and the response to therapy. 3) It is safe, convenient and of no side effects

    Chronic diseases (CD) are a public health emergency in Mexico. Despite concern regarding the financial burden of CDs in the country, economic studies have focused only on diabetes, hypertension, and cancer. Furthermore, these estimated financial burdens were based on hypothetical epidemiology models or ideal healthcare scenarios. The present study estimates the annual expenditure per patient and the financial burden for the nine most prevalent CDs, excluding cancer, for each of the two largest public health providers in the country: the Ministry of Health (MoH) and the Mexican Institute of Social Security (IMSS). Using the Mexican National Health and Nutrition Survey 2012 (ENSANUT) as the main source of data, health services consumption related to CDs was obtained from patient reports. Unit costs for each provided health service (e.g. consultation, drugs, hospitalization) were obtained from official reports. Prevalence data was obtained from the published literature. Annual expenditure due to health services consumption was calculated by multiplying the quantity of services consumed by the unit cost of each health service. The most expensive CD in both health institutions was chronic kidney disease (CKD), with an annual unit cost for MoH per patient of US$ 8,966 while for IMSS the expenditure was US$ 9,091. Four CDs (CKD, arterial hypertension, type 2 diabetes, and chronic ischemic heart disease) accounted for 88% of the total CDs financial burden (US$ 1.42 billion) in MoH and 85% (US$ 3.96 billion) in IMSS. The financial burden of the nine CDs analyzed represents 8% and 25% of the total annual MoH and IMSS health expenditure, respectively. The financial burden from the nine most prevalent CDs, excluding cancer, is already high in Mexico. This finding by itself argues for the need to improve health promotion and disease detection, diagnosis, and treatment to ensure CD primary and secondary prevention. If the status quo remains, the financial burden could be higher.

    2018-03-12

    Today, many healthcare or dementia organizations, clinicians, and companies emphasize the importance of detection of Alzheimer's disease in an early phase. This idea has gained considerable momentum due to the development of biomarkers, the recent FDA and EMA approval of three amyloid tracers, and the failure of a number of recent therapeutic trials conducted in the early dementia phase. On the one hand, an early etiological diagnosis can lead to early and more efficacious intervention. On the other hand, it is questioned how early an etiological diagnosis is beneficial to the patient. Here we consider ethical issues related to the process of biomarker testing and the impact on the diagnostic disclosure to patients with mild cognitive impairment due to prodromal Alzheimer's disease. A systematic review of the theoretical bioethics literature was performed by using electronic databases. The review was limited to articles published in English between 2003 and 2016. A total of twenty articles were included in our effort to make an analysis of the ethical challenges. One of the biggest challenges was the uncertainty and the predictive value of the biomarker-based diagnosis where patients can be amyloid positive without full certainty whether or when they will develop symptomatic decline due to Alzheimer's disease. Another challenge was the tension between the right to know versus the wish not to know, the limited efficacy of currently available treatment options, and the opportunities and consequences after receiving such an early diagnosis. Based on the results and the additional comments in the discussion, several unanswered questions emerged. Therefore, careful consideration of all these ethical issues is required before the disclosure of a biomarker-based diagnosis to the patient with mild cognitive impairment due to Alzheimer's disease.

    Aim of the present study was to determine the prevalence of coronary artery anomalies in children with congenital heart disease. Data of 1138 consecutive patients who were referred for cardiac catheterization and angiography for assessment of coronary anomaly between January 2005 and December 2009 were retrospectively analyzed. Total of 515 patients whose coronary arteries could be examined through left ventricle and aortic root injection were included in the study. Of 515 angiograms with visible coronaries, 42 patients (20 males, 22 females; mean age: 5.3±2.0 years) were found to have final diagnosis of coronary anomaly. Prevalence of coronary artery anomalies was 8.16% in this study. It was determined that 38 (90.4%) were anomalies of origination, 2 (4.8%) were anomalies of intrinsic coronary arterial anatomy, and 2 (4.8%) were anomalies of coronary termination. Most common coronary artery abnormality was anomalous origin of the right coronary artery from the left aortic sinus (16 patients; 38.1%), and the most common congenital heart disease was tetralogy of Fallot (18 patients; 42.9%). Recognizing variability of coronary artery anomalies is critical when considering surgical or interventional therapies in children with congenital heart disease.

    Background The benefits of expressive writing have been well documented among several populations, but particularly among those who report feelings of dysphoria. It is not known, however, if those diagnosed with Major Depressive Disorder (MDD) would also benefit from expressive writing. Methods Forty people diagnosed with current MDD by the Structured Clinical Interview for DSM-IV participated in the study. On day 1 of testing, participants completed a series of questionnaires and cognitive tasks. Participants were then randomly assigned to either an expressive writing condition in which they wrote for 20 min over three consecutive days about their deepest thoughts and feelings surrounding an emotional event (n=20), or to a control condition (n=20) in which they wrote about non-emotional daily events each day. On day 5 of testing, participants completed another series of questionnaires and cognitive measures. These measures were repeated again 4 weeks later. Results People diagnosed with MDD in the expressive writing condition showed significant decreases in depression scores (Beck Depression Inventory and Patient Health Questionnaire-9 scores) immediately after the experimental manipulation (Day 5). These benefits persisted at the 4-week follow-up. Limitations Self-selected sample. Conclusions This is the first study to demonstrate the efficacy of expressive writing among people formally diagnosed with current MDD. These data suggest that expressive writing may be a useful supplement to existing interventions for depression. PMID:23790815

    Coexistence of an ocular surface disease can mask the typical features of ocular surface squamous neoplasia (OSSN). The purpose of this study was to evaluate high resolution optical coherence tomography (HR-OCT) as an adjunct in the detection and differentiation of OSSN within coexisting ocular surface pathologies. Retrospective study of 16 patients with ocular surface disease and lesions suspicious for OSSN that were evaluated with HR-OCT. HR-OCT images of the lesions were taken to look for evidence of OSSN. Biopsies were performed in all cases, and the HR-OCT findings were compared to the histological results. Of the 16 patients with OSSN and a coexisting ocular surface disease, 12 were found to have OSSN by HR-OCT and all were subsequently confirmed by biopsy. Two patients had OSSN with rosacea, one with pingueculum, two within pterygia, one with Salzmann' nodular degeneration, six with limbal stem cell deficiency (LSCD)/scarring. In all 12 cases HR-OCT images revealed classical findings of hyper-reflective, thickened epithelium and an abrupt transition from normal to abnormal epithelium. OSSN was ruled out by HR-OCT in four cases (2 Salzmann's, 1 mucous membrane pemphigoid, and 1 LSCD). Negative findings were confirmed by biopsy. HR-OCT was used to follow resolution of the OSSN in positive cases, and it detected recurrence in 1 case. While histopathology is the gold standard in the diagnosis of OSSN, HR-OCT can be used to noninvasively detect the presence of OSSN in patients with coexisting ocular conditions.

    Peripheral Arterial Disease (PAD) is the narrowing of the functional area of the artery generally due to atherosclerosis. It affects between 8-12 million people in the United States and if untreated this can lead to ulceration, gangrene and ultimately amputation. The current diagnostic method for PAD is the ankle-brachial index (ABI). The ABI is a ratio of the patient's systolic blood pressure in the foot to that of the brachial artery in the arm, a ratio below 0.9 is indicative of affected vasculature. However, this method is ineffective in patients with calcified arteries (diabetic and end-stage renal failure patients), which falsely elevates the ABI recording resulting in a false negative reading. In this paper we present our results in a pilot study to deduce optical tomography's ability to detect poor blood perfusion in the foot. We performed an IRB approved 30 patient study, where we imaged the feet of the enrolled patients during a five stage dynamic imaging sequence. The patients were split up into three groups: 10 healthy subjects, 10 PAD patients and 10 PAD patients with diabetes and they were imaged while applying a pressure cuff to their thigh. Differences in the magnitude of blood pooling in the foot and rate at which the blood pools in the foot are all indicative of arterial disease.

    Tay-Sachs disease (TSD), Sandhoff disease (SD) and variants are caused by deficient activity of the lysosomal enzymes hexosaminidase A (HA) and total hexosaminidase (TH) (hexosaminidase A plus B), respectively. For diagnosis, these enzymes are usually measured in plasma or extracts of leukocytes. We describe methods for the assay of hexosaminidase A and total hexosaminidase activities in dried blood spots (DBSs) on filter paper. We studied 163 healthy controls, 9 Tay-Sachs patients, 4 Sandhoff patients, 18 obligate carriers and the newborn-screening cards from two patients with Tay-Sachs and one patient with Sandhoff disease. To tubes containing a 3-mm-diameter blood spot, we added elution liquid and substrate solution. After incubation at 37 degrees C, the amount of hydrolyzed product was compared with a calibrator to allow the quantification of enzyme activity. The described methodology is useful to distinguish patients with Tay-Sachs disease or Sandhoff disease from carriers and controls using samples that are sufficiently stable to be transported to the testing laboratory by mail. The diagnosis of both diseases from a newborn-screening card (NSC) was clearly demonstrated, even after storage for up to 38 months at room temperature. The newborn-screening card has been added to the biological materials that allow the identification of patients with Tay-Sachs disease and Sandhoff disease.

    Bronchopulmonary dysplasia (BPD) is a chronic lung disease of prematurity. The new definition of BPD was introduced in 2001. It combined two existing BPD definitions - oxygen dependency at 28 days of life and at 36 weeks of postmenstrual age. New definition divided BPD into three forms: mild, moderate and severe. Despite significant progress in neonatal intensive care and increasing survival of extremely immature infants the incidence of BPD is not decreasing. The etiopathology of new disease is still discussed. The aim of the study was to assess the frequency and severity of BPD in very low birth weight (VLBW) neonates (BPD definition. We retrospectively analyzed the case records of 244 neonates boys - 112; girls - 132) at gestational age weeks 23-28 (26.4+/-1.4) treated at the Institute of Mother and Child in Warsaw between 1999 and 2004. Of these 166 (68%) infants were evaluable at 36 weeks of postmenstrual age and had BPD evaluation according to the new definition. The following variables were analyzed according to BPD status: sex distribution, gestational age, body weight at birth severity, of respiratory distress syndrome (RDS), intrauterine or late infections, congenital or late pneumonia, patent ductus arteriosus (PDA) and intraventricular haemorrhage (IVH) grade III or IV. BPD was present in 126 (76%) neonates including: severe BPD in 23 (18%), moderate 19 (15%) and mild BPD in 84 (67%) of children. Neonates with BPD had lower gestational age (26.4+/-1.3 vs 27.4+/-0.9 week, pBPD. The rates of late onset sepsis, late pneumonia and PDA were statistically higher in children with BPD than in those without BPD (respectively 70 vs 33%, 72 vs 35% and 51 vs 20% pBPD had higher rate of late infections (pBPD in VLBV neonates is high (76%) but in the majority of cases the disease is mild (67%); 2. Severe BPD was more common in neonates with late onset sepsis and IVH grade III or IV; 3. The BPD risk factors are: low gestational age, low birth weight, as well as late

    The purpose of this study is to evaluate the clinical value of PSA (prostate specific antigen) and fPSA(free prostate specific antigen) in differentiating prostate disease. CLIA was used to quantitatively assay PSA, fPSA and fPSA/PSA in 30 cases of normal controls, 32 cases of prostate cancer patients and 76 cases of BPH patients. The result showed that if liminal value of PSA was set at 4 ng/mL, the diagnostic sensitivity and specificity of prostate cancer were 100% and 50.6% respectively. Meanwhile, if liminal value of fPSA/PSA set at 16% was added, the diagnostic sensitivity and specificity of prostate cancer were 100% and 85.3% respectively. It was concluded that the combining assay of PSA and fPSA could increase the diagnostic specificity of prostate cancer in a certain degree

    To evaluate the specificity of a canine pancreas-specific lipase (cPSL) assay for diagnosing pancreatitis in dogs without clinical or histologic evidence of the disease. 20 dogs from another study with macroscopic evidence of pancreatitis and 44 dogs surrendered for euthanasia or expected to die. Prior to death, physical examination of each dog was performed and blood samples were collected for serum biochemical, serum cPSL, and hematologic analyses. After death, the pancreas was removed, sectioned in 1- to 2-cm slices, and evaluated by a pathologist. Dogs were classified by whether they had clinical or macroscopic pancreatitis. Each pancreatic section was histologically examined, and mean cumulative scores (MCSs) were assigned for 8 histologic characteristics. For each characteristic, comparisons were made between dogs with and without pancreatitis to establish histologic criteria for lack of evidence of pancreatitis. For all histologic characteristics except lymphocytic infiltration, the median MCS differed significantly between dogs with and without pancreatitis. Dogs were categorized as having no histologic evidence of pancreatitis when the MCSs for neutrophilic infiltration, pancreatic necrosis, peripancreatic fat necrosis, and edema were 0.0. On the basis of these criteria, 40 dogs were classified as having no evidence of pancreatitis. The cPSL concentration was within reference limits in 38 of these 40 dogs and was less than the cutoff value for diagnosing pancreatitis (400 μg/L) in 39 of the 40 dogs, resulting in a specificity of 97.5% (95% confidence interval, 86.8% to 99.9%). The cutoff cPSL value used in this study may be useful for diagnosing pancreatitis in dogs with a lack of histologic lesions consistent with pancreatitis and for which pancreatitis is not considered a major differential diagnosis.

    Life-long gluten-free diet (GFD) is the only recognised treatment for coeliac disease (CD). The present study aimed to determine the nutritional adequacy of the 'no detectable gluten' diet. Seven-day prospective food intake was assessed in 55 patients who were adherent to a GFD for more than 2 years and in 50 newly-diagnosed age- and sex-matched patients (18-71 years, 24% male) studied prospectively over 12 months on GFD. Historical precoeliac intake was also assessed in the latter group. Intake was compared with Australian Nutritional Recommendations and the Australian population data. Nutritional intake was similar between groups. Of macronutrients, only starch intake fell over 12 months (26% to 23%, P = 0.04). Fibre intake was inadequate for all except in diet-experienced men. More than one in 10 of both newly-diagnosed and experienced women had inadequate thiamin, folate, vitamin A, magnesium, calcium and iron intakes. More than one in 10 newly-diagnosed men had inadequate thiamin, folate, magnesium, calcium and zinc intakes. Inadequate intake did not relate to nutrient density of the GFD. Inadequacies of folate, calcium, iron and zinc occurred more frequently than in the Australian population. The frequency of inadequacies was similar pre- and post-diagnosis, except for thiamin and vitamin A, where inadequacies were more common after GFD implementation. Dietary intake patterns at 12 months on a GFD are similar to longer-term intake. Dietary inadequacies are common and may relate to habitual poor food choices in addition to inherent deficiencies in the GFD. Dietary education should also address the achievement of adequate micronutrient intake. Fortification of GF foods also need to be considered. © 2012 The Authors Journal of Human Nutrition and Dietetics © 2012 The British Dietetic Association Ltd.

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

    2013-01-01

    Background In theory, cerebral biopsies could provide the diagnosis in a significant proportion of patients with neurodegenerative diseases, however, there are considerable ethical barriers. Previous series of cerebral biopsies have shown variable diagnostic accuracy but have understandably suffered because of lack of post-mortem tissue with which to compare the diagnosis. To determine the accuracy of such biopsies in neurodegenerative disease we took small biopsy-sized samples of predominantly fresh post-mortem brain tissue from frontal and temporal lobes in 62 cases. These were processed as for a biopsy and stained for H&E, p62, tau, Aβ, α-synuclein, and TDP-43. The sections were assessed blind by 3 neuropathologists and the results compared with the final post-mortem diagnosis. Results The agreement and sensitivity in most cases was good especially: controls; Alzheimer’s disease (AD); multiple system atrophy (MSA); frontotemporal lobar degeneration with TDP-43 positive inclusions and/or motor neurone disease (FTLD-TDP/MND); Huntington’s disease (HD); corticobasal degeneration (CBD) / microtubular associated protein tau mutation cases with CBD-like features (CBD/MAPT); and combined AD- Dementia with Lewy Bodies (AD-DLB) where the sensitivity on assessing both brain regions varied between 75-100%. There was poor sensitivity for progressive supranuclear palsy (PSP) and amyotrophic lateral sclerosis (ALS) (both 0%), but moderate sensitivity for pure DLB (60%). The temporal lobe assessment was marginally more accurate than the frontal lobe but these were only slightly worse than both combined. Conclusions The study shows that with certain caveats the cerebral biopsy in life should be a viable method of accurately diagnosing many neurodegenerative diseases. PMID:24252649

  7. Lymphography and computed tomography of abdominal nodes in newly diagnosed patients with Hodgkin's disease in clinical stage I-III

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

    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.

    We examine the reliability of single and repeated blood pressure measurements at ankle, toe, and arm levels for the diagnosis of peripheral arterial disease (PAD) by laser Doppler flowmetry. Segmental pressures were measured in 200 patients with known or suspected PAD. Segmental indices were calculated using (1) one measurement [M-1], two measurements [M-2], or by a predefined reproducibility criterion (RC) as well as (2) by using one brachial blood-pressure (BBP-one) or correspondent to each segmental pressure (BBP-all) as reference. The agreement in diagnosis of PAD by Cohen's Kappa was κ = 0.930 when comparing RC to M-1, and κ = 0.977 when comparing RC to M-2. The same comparison showed excellent relative reliability for segmental indices (all intra-class correlation coefficients (ICC) ≥ 0.980). Diagnostic classification agreement for BBP-all versus BBP-one were κ = 0.831 for RC, κ = 0.804 for M-1, and κ = 0.847 for M-2. The relative reliability analysis showed excellent correlation in segmental indices (all ICC ≥ 0.957). The study shows minimal difference in segmental indices and diagnostic classification when comparing calculations based on the listed strategies. However, the study indicated that it is important to measure BBPs correspondent to each segmental pressure. (paper)

    Despite multiple guidelines advocating against routine radiological evaluation for metastases in women with early stage breast cancer, imaging is still frequently overused. The objective of this study was to assess doctor's views on imaging guidelines, and an attempt to establish why personal and local clinical practice patterns regarding imaging may differ from current guidelines. Canadian doctors who treat breast cancer were invited by email to complete an online survey developed by members of the research team. Responses were received from 173 physicians (26% response rate). Most (82%) indicated awareness of at least one published imaging guideline. Sixty per cent indicated that they had read the recommendations of the 2012 American Society of Clinical Oncology 'Top 5' list for choosing wisely in oncology imaging and, of those, 81% agreed with it. However, most indicated that this recommendation has not influenced them to order less imaging. Over 95% of doctors identified suspicious history, physical examination findings and inflammatory breast cancer as important factors for performing imaging. The majority did not feel that patient demand, fear of litigation or ease of access to imaging influenced their ordering for imaging. The majority of breast cancer doctors are aware of and generally agree that guidelines pertaining to staging imaging for early breast cancer are reflective of evidence. Despite this, adherence is variable and factors such as local practice patterns and disease biology may play a role. Alternative strategies, beyond simply publishing recommendations, are therefore required if there is to be a sustained change in doctor behaviour. © 2014 John Wiley & Sons, Ltd.

    The aim of this study was to evaluate the diagnostic potential of cardiac 123 I-labelled metaiodobenzylguanidine ( 123 I-MIBG) scintigraphy in idiopathic Parkinson's disease (PD). The diagnosis was confirmed by positron emission tomography (PET) imaging with 11 C-labelled 2β-carbomethoxy-3β-(4-fluorophenyl)-tropane ( 11 C-CFT) and 11 C-raclopride (together designated as dopamine PET). Cardiac 123 I-MIBG scintigraphy and dopamine PET were performed for 39 parkinsonian patients. To estimate the cardiac 123 I-MIBG uptake, heart to mediastinum (H/M) ratios in early and delayed images were calculated. On the basis of established clinical criteria and our dopamine PET findings, 24 patients were classified into the PD group and 15 into the non-PD (NPD) group. Both early and delayed images showed that the H/M ratios were significantly lower in the PD group than in the NPD group. When the optimal cut-off levels of the H/M ratio were set at 1.95 and 1.60 in the early and delayed images, respectively, by receiver-operating characteristic analysis, the sensitivity of cardiac 123 I-MIBG scintigraphy for the diagnosis of PD was 79.2 and 70.8% and the specificity was 93.3 and 93.3% in the early and delayed images, respectively. In the Hoehn and Yahr 1 and 2 PD patients, the sensitivity decreased by 69.2 and 53.8% in the early and delayed images, respectively. In early PD cases, cardiac 123 I-MIBG scintigraphy is of limited value in the diagnosis, because of its relatively lower sensitivity. However, because of its high specificity for the overall cases, cardiac 123 I-MIBG scintigraphy may assist in the diagnosis of PD in a complementary role with the dopaminergic neuroimaging. (orig.)

    The Loewenstein-Acevedo Scale for Semantic Interference and Learning (LASSI-L) is a novel cognitive test that measures recovery from proactive semantic interference, which may be an early cognitive marker of Alzheimer's disease (AD). To generate normative data for a Spaniard population and to validate the LASSI-L for the diagnosis of amnestic mild cognitive impairment (aMCI) and mild AD. We performed a cross-sectional study in which 97 healthy participants, 34 with aMCI, and 33 with mild AD were studied with LASSI-L and a comprehensive neuropsychological protocol. The overlapping strategy analysis was used to maximize the sample size and to provide age- and education-adjusted normative data using a logistic regression analysis. Internal consistency was 0.932. Convergent validity with the Free and Cued Selective Reminding Test was moderate. LASSI-L raw scores were correlated with age and years of education, but not gender. The area under the curve for discriminating between healthy controls and aMCI was 0.909, and between healthy controls and mild AD was 0.986. LASSI-L sub-scores representing maximum storage capacity, recovery from proactive interference, and delayed recall yielded the highest diagnostic accuracy. The LASSI-L is a reliable and valid test for the diagnosis of aMCI and mild AD. The age and education influences on the performance of the test and normative data are provided. LASSI-L merits further studies to evaluate its ability to detect preclinical AD and predict progression to aMCI and early dementia.

    Full Text Available MYCN is a well-known oncogene overexpressed in different human malignancies including neuroblastoma, rhabdomyosarcoma, medulloblastoma, astrocytoma, Wilms’ tumor, and small cell lung cancer. While neuroblastoma is one of the most common childhood malignancies, in adults it is extremely rare and its treatment is based on pediatric protocols that take into consideration stage and genotypic features, such as MYCN amplification. Although neuroblastoma therapy has evolved, identification of early stage patients who need chemotherapy continues to pose a therapeutic challenge. The emerging prognostic role of MYCN phenotype of this disease is currently under investigation as it may redefine MYCN amplified subgroups. We describe an unusual case of adult neuroblastoma with MYCN amplification diagnosed incidentally and discuss possible therapeutic dilemmas.

    BACKGROUND: The rates of Sexually transmitted diseases (STDs) in England have been rising steadily since the mid 1990s, making them a major public health concern. In 2003, 672,718 people were diagnosed with an STD in England, and around one third of those cases were diagnosed in London. RESULTS: Using GeoReveal v1.1 for Windows, we produced Web-based interactive choropleth maps of diagnoses of STDs by Primary Care Trust (PCT) in London for the years from 1997 to 2003 http://healthcybermap.org/PCT/STDs/. These maps are in Scalable Vector Graphics (SVG) format and require a freely available Adobe SVG browser plug-in to be displayed. They are based on data obtained from the House of Commons Hansard Written Answers for 15 October 2004. They show steadily rising rates of STDs in London over the covered seven-year period. Also, one can clearly see on the maps that PCTs located in central London had the highest numbers of STD diagnoses throughout the mapped seven years. A companion bar chart allows users to instantly compare the STD figure of a given PCT for a given year against the average figure for all 25 mapped PCTs for the same year, and also compare those figures across all seven years. The maps offer users a rich set of useful features and functions, including the ability to change the classification method in use, the number of ranges in the map, and the colour theme, among others.

    2521 patients of the Lodz Outpatient Endocrinologic Clinic (2290 females, 231 males; inhabitants of the central region of Poland were included in the study. The obtained results indicate that: 1) KI administration neither increased the number of exacerbations of hyperthyroidism nor affected the onset of new cases of that disease in 1986. 2) The same can be said about the cases of thyroiditis and hypothyroidism. 3) No increase of ATMA or ATG antibodies ''prevalence, as well as no elevation of those antibodies'' titres after KI prophylactic dose were observed in the patients with Grave's disease and chronic thyroiditis, when compared to persons who did not take Lugol's iodine. 4) The course of the majority of diseases diagnosed in 1986, evaluated with use of the, so called, test for analysis of trends, became unchanged. 5) There were adverse side effects noted after KI in 32 patients out of all the examined 774 patients (i.e., in 4.13%); five of the affected patients required medical care. 6) After iodine tincture; side effects occurred in three patients in the group of 35 patients included in the examination, i.e., in 8.57%; none of the affected patients required medical care. 7) Our results, comprising the four year observation period after Chernobyl accident, do not indicate any increased incidence of malignant neoplasms of the thyroid gland, what confirms the apparent theoretical data; much longer observation time is necessary to reveal phenomena of scholastic type (10-15 years).

    Proteinase-activated receptor 2 (PAR-2) has been shown to promote both neurotoxic and neuroprotective effects. Similarly, other routinely used nonspecific markers of neuronal damage can be found in cerebrospinal fluid (CSF) and can be used as biomarkers for different neurodegenerative disorders. Using enzyme-linked immunosorbent assays and western blotting we assessed PAR-2, total-tau, phospho-tau, beta-amyloid levels, and protein 14-3-3 in the CSF of former patients who had undergone a neuropathological autopsy after death and who had been definitively diagnosed with a prion or other neurodegenerative disease. We did not find any significant correlation between levels of PAR-2 and other biomarkers, nor did we find any differences in PAR-2 levels between prion diseases and other neurodegenerative conditions. However, we confirmed that very high total-tau levels were significantly associated with definitive prion diagnoses and exhibited greater sensitivity and specificity than protein 14-3-3, which is routinely used as a marker. Our study showed that PAR-2, in CSF, was not specifically altered in prion diseases compared to other neurodegenerative conditions. Our results also confirmed that very high total-tau protein CSF levels were significantly associated with a definitive Creutzfeldt-Jakob disease (CJD) diagnosis and should be routinely tested as a diagnostic marker. Observed individual variability in CSF biomarkers provide invaluable feedback from neuropathological examinations even in "clinically certain" cases.

    Rheumatoid Arthritis (RA) is a chronic systemic inflammatory disease where assessment of disease activity is essential for management of patient. Currently, many composite scoring systems are used for evaluation of disease activity but they are mainly clinical-based. As several haematological parameters are altered due to systemic inflammatory process in RA, this study was intended to evaluate role of common haematological parameters to assess disease activity in RA. To find out the association of disease activity of Rheumatoid Arthritis (RA) with platelet count, Mean Platelet Volume (MPV) and Haemoglobin (Hb) level so that these cost-effective haematological parameters can be used as additional factors to assess disease activity. This hospital based cross-sectional study was done on newly diagnosed patients of RA along with age and sex matched healthy control population. Patients suffering from malignancies, renal failure, diabetes mellitus or RA patients on drug therapy were excluded. Clinically, disease activity of RA was measured using DAS 28-3 Score (Modified Disease Activity Score using three variables- tender joint count, swollen joint count and ESR). Haematological parameters were measured by automated cell counter. Total 80 cases were selected (60 female and 20 male). 48 patients with high disease activity (DAS 28-3>5.1) were labelled as Group-A and 32 with low to moderate disease activity (DAS 28-3 ≤5.1) as Group- B. Mean platelet count of patients of group A and group B were 4.53 lac/cmm and 2.17 lac/cmm respectively (p <0.001). MPV mean in group A and B were 11.86 fl and 10.19 fl respectively (p <0.001). Mean Hb (g/dl) was 10.05 and 12.25 for group A and B respectively (p=0.001) for male patients while in females it was 10.12 and 11.91 for group A and B, respectively (p=0.003). Mean platelet count and MPV in control population were 2.07 lac/cmm and 9.4 fl, respectively while mean Hb (g/dl) was 13.31 (male) and 12.01 (female). In our study it was

    Full Text Available An intensive induction regimen, consisting of idarubicin and high dose cytarabine, was assessed in 19 adult patients, median age 44 years, with newly diagnosed precursor-B acute lymphoblastic leukemia (ALL. Patients achieving a complete response (CR were given an attenuated consolidation course. The primary endpoints were induction death rate and incidence of serious non-hematological toxicity. Grades 3–4 diarrhoea occurred in 47% of patients during induction. Two patients (11% died during induction therapy, and 2 were withdrawn due to resistant disease or prolonged marrow hypoplasia. Fifteen patients achieved CR (79%, but levels of minimal residual disease (MRD after induction were comparable with those previously observed using a modified pediatric protocol. Overall survival at 5 years was 36.8% while leukemia-free survival was 44.1%. An intensive AML protocol used in adults with ALL resulted in substantial toxicity and provided similar levels of cytoreduction to conventional ALL protocols, without improving long-term outcomes.

    Patients with inflammatory bowel disease (IBD) are at high risk for nutritional deficiencies because of long-term inflammation in the gut mucosa and decreased oral intake. Because inflammation responses affect serum micronutrient concentrations, serum levels are limited in reflecting body nutrient status in acute and chronic illness. We investigated the usefulness of measuring trace elements in hair as reliable markers of nutritional status compared to serum levels in children with IBD. We retrospectively analyzed pediatric patients newly diagnosed with Crohn's disease (n = 49) and ulcerative colitis (n = 16) and controls (n = 29) from 2012 to 2016. Serum micronutrient levels, inflammatory markers, and hair trace element content were evaluated and compared at the time of diagnosis and before initiating treatment. Serum calcium (p elements, iron (p = 0.033), selenium (p = 0.017), and manganese (p = 0.009) differed significantly between the groups. Serum micronutrient levels need cautious interpretation in conjunction with inflammatory markers. Hair mineral and trace element measurement may support understanding micronutrient status in children with IBD.

    Optimizing risk assessment may reduce use of advanced diagnostic testing in patients with symptoms suggestive of stable coronary artery disease (CAD). Detection of diastolic murmurs from post-stenotic coronary turbulence with an acoustic sensor placed on the chest wall can serve as an easy, safe, and low-cost supplement to assist in the diagnosis of CAD. The aim of this study was to evaluate the diagnostic accuracy of an acoustic test (CAD-score) to detect CAD and compare it to clinical risk stratification and coronary artery calcium score (CACS). We prospectively enrolled patients with symptoms of CAD referred to either coronary computed tomography or invasive coronary angiography (ICA). All patients were tested with the CAD-score system. Obstructive CAD was defined as more than 50 % diameter stenosis diagnosed by quantitative analysis of the ICA. In total, 255 patients were included and obstructive CAD was diagnosed in 63 patients (28 %). Diagnostic accuracy evaluated by receiver operating characteristic curves was 72 % for the CAD-score, which was similar to the Diamond-Forrester clinical risk stratification score, 79 % (p = 0.12), but lower than CACS, 86 % (p < 0.01). Combining the CAD-score and Diamond-Forrester score, AUC increased to 82 %, which was significantly higher than the standalone CAD-score (p < 0.01) and Diamond-Forrester score (p < 0.05). Addition of the CAD-score to the Diamond-Forrester score increased correct reclassification, categorical net-reclassification index = 0.31 (p < 0.01). This study demonstrates the potential use of an acoustic system to identify CAD. The combination of clinical risk scores and an acoustic test seems to optimize patient selection for diagnostic investigation.

    In China, the prevalence of chronic obstructive pulmonary disease (COPD) in persons 40 years of age or older is estimated at 8.2%, but this is likely a substantial underestimate. Eight secondary hospitals which didn't have spirometries were chosen randomly in Hunan province of central south China. Physician subjects at these hospitals underwent a one-hour training course on the Chinese COPD guidelines. Physicians answered questionnaires assessing their knowledge of the guidelines before and after the training session. The mean correct scores of questionnaires were compared before and after training. Four out of the eight hospitals were given access to spirometry. Eligible patient subjects underwent spirometry testing prior to the physician visit. After seeing the patient, physicians were asked to answer a questionnaire relating to the diagnosis and severity of COPD. Physicians were then given the results of the spirometry, and asked to answer the same questionnaire. Physicians' responses before and after receiving the spirometry results were compared. 225 physicians participated in the training session. 207 questionnaires were completed. Mean scores (out of 100) before and after the training were 53.1 ± 21.7 and 93.3 ± 9.8, respectively. 18 physicians and 307 patient subjects participated in the spirometry intervention. Based on spirometric results, the prevalence of COPD was 38.8%. Physicians correctly identified the presence of COPD without spirometric data in 85 cases (76.6%); this increased to 117 cases (97.4%) once spirometric data were available. Without spirometric data, physicians incorrectly diagnosed COPD in 38 patients; this decreased to 6 patients once spirometric data were available. Spirometric data also improved the ability of physicians to correctly grade COPD severity. Simple educational training can substantially improve physicians' knowledge relating to COPD. Spirometry combined with education improves the ability of physicians to diagnose COPD

    Full Text Available BACKGROUND: Prospective data is sparse on the association between ischemic heart disease (IHD and ankylosing spondylitis (AS in the young. The purpose of this population-based, age- and sex-matched follow-up study was to investigate the risk of IHD in young patients with newly diagnosed AS. METHODS: A total of 4794 persons aged 18 to 45 years with at least two ambulatory visits in 2001 with the principal diagnosis of AS were enrolled in the AS group. The non-AS group consisted of 23970 age- and sex-matched, randomly sampled subjects without AS. The three-year IHD-free survival rate and cumulative incidence of IHD were calculated using the Kaplan-Meier method. The Cox proportional hazards regression model was used to estimate the hazard ratio of IHD after controlling for demographic and cardiovascular co-morbidities. RESULTS: During follow-up, 70 patients in the AS group and 253 subjects in the non-AS group developed IHD. The cumulative incidence rate of IHD over time was higher in the AS group than the non-AS group. The crude hazard ratio of IHD for the AS group was 1.47 (95% CI, 1.13 to 1.92; p = 0.0043 and the adjusted hazard ratio after controlling for demographic characteristics and comorbid medical disorders was 1.47 (95% CI, 1.13 to 1.92; p = 0.0045. CONCLUSIONS: This study showed an increased risk of developing IHD in young patients with newly diagnosed AS.

    International Nuclear Information System (INIS)

    Zammurrad, S.; Munir, W.; Farooqi, A.

    2013-01-01

    Objective: To correlate disease activity score (DAS-28) in the patients with rheumatoid arthritis (RA) with and without secondary fibromyalgia. Study Design: Comparative cross-sectional study. Place and Duration of Study: Department of Rheumatology, Pakistan Institute of Medical Sciences, Islamabad, from November 2011 to April 2012. Methodology: Patients aged above 16 years diagnosed to have rheumatoid arthritis according to ACR/EULAR criteria 2010 were included in the study. Fibromyalgia (FM) was diagnosed by ACR 1990 criteria. Patients of other autoimmune diseases or psychiatric illnesses were excluded. DAS was determined and compared using t-test with significance at p < 0.05. Results: The mean age of study subjects was 42.9 years. Thirty one out of total 138 patients had fibromyalgia (22.4%). Female gender was predominant (92.0%); being 96.8% in patients with and in 88.2% without fibromyalgia. The average DAS score was high (5.3 + 1.5) in fibromyalgia patients compared to those without fibromyalgia (3.9 + 1.2); this difference in mean value was statistically significant (p = < 0.001). Conclusion: DAS-28 is a useful tool for assessing rheumatoid arthritis disease status in outpatient setting, however, increased disease activity must be assessed for possible co-existence of fibromyalgia which can spuriously give high DAS value and adversely affect treatment decision.

    To investigate if lymphopenia is associated with clinical manifestations, disease activity and prognosis in systemic lupus erythematosus (SLE). The charts of 186 paediatric patients with SLE diagnosed between 1985 and 2006 in a medical centre were retrospectively reviewed. Lymphocyte counts were recorded at the time of SLE diagnosis and SLE flares. Global disease activity was quantified by the SLE Disease Activity Index (SLEDAI). Cumulative organ damage was assessed by the ACR/Systemic Lupus International Collaborating Clinics (SLICC) damage index. Lymphopenia (oral ulcers, leucopenia, anti-dsDNA antibodies and C4 decrease. At the time of flares, lymphopenia was significantly associated with anti-dsDNA antibodies, methylprednisolone pulse therapy, disease activity and organ damage. Using multivariate logistic regression, marked lymphopenia was independently associated with neuropsychiatric manifestations [odds ratio (OR) 7.41, 95% confidence interval (CI) 1.99-27.0], and protective from LN (OR 0.13, 95% CI 0.03-0.53). Lymphopenia at SLE flares is associated with disease activity and organ damage. Marked lymphopenia is independently associated with neuropsychiatric manifestations.

    BACKGROUND AND AIMS: Crohn's disease prevalence increases with increasing latitude. Because most vitamin D comes from sunlight exposure and murine models of intestinal inflammation have demonstrated beneficial effects of 1,25-(OH)(2) vitamin D treatment, we hypothesised that Crohn's disease...... activity is associated with low vitamin D levels. METHODS: In a cross-sectional study of 182 CD patients and 62 healthy controls, we measured serum 25-OH vitamin D.

    Highlights: •We compared sizes of known ductal carcinoma in situ (DCIS) on pre-operative breast MRI at 3 T and 1.5 T with final pathology sizes. •DCIS sizes on 3 T MRI correlated better with pathologic sizes than 1.5 T MRI. •Imaging features of DCIS, including morphology and kinetics, were similar at 3 T and 1.5 T MRI. -- Abstract: Objectives: While 3 T breast magnetic resonance imaging has increased in use over the past decade, there is little data comparing its use for assessing ductal carcinoma in situ (DCIS) versus 1.5 T. We sought to compare the accuracies of DCIS extent of disease measures on pre-operative 3 T versus 1.5 T MRI. Methods: This institutional review board-approved prospective study included 20 patients with ductal carcinoma in situ diagnosed by core needle biopsy (CNB) who underwent pre-operative breast MRI at both 3 T (resolution = 0.5 mm × 0.5 mm × 1.3 mm) and 1.5 T (0.85 mm × 0.85 mm × 1.6 mm). All patients provided informed consent, and the study was HIPPA compliant. Lesion sizes and imaging characteristics (morphologic and kinetic enhancement) were recorded for the 3 T and 1.5 T examinations. Lesion size measures at both field strengths were correlated to final pathology, and imaging characteristics also were compared. Results: Of the initial cohort of 20 patients with CNB-diagnosed DCIS, 19 underwent definitive surgery. Median DCIS sizes of these 19 patients were 6 mm (range: 0–67 mm) on 3 T, 13 mm (0–60 mm) on 1.5 T, and 6 mm (0–55 mm) on surgical pathology. Size correlation between MRI and pathology was higher for 3 T (Spearman's ρ = 0.66, p = 0.002) than 1.5 T (ρ = 0.36, p = 0.13). In 10 women in which a residual area of suspicious enhancement was identified on both field strengths, there was agreement of morphologic description (NME vs. mass) in nine, and no significant difference in dynamic contrast enhanced kinetics at 3 T compared to 1.5 T. Conclusions: Pre-operative breast MRI at 3 T provided higher

    Children with chronic kidney disease (CKD) develop many metabolic changes in blood that often necessitate frequent biochemical analysis. Serum analysis is an invasive and painful procedure. It would be highly beneficial if a noninvasive alternative process to serum analysis in children were identified. Saliva can be collected noninvasively, repeatedly, and without the use of healthcare personnel. The aims of this study were to compare serum and salivary urea and creatinine levels in children with CKD and healthy controls, and to determine if salivary creatinine and urea levels can be used to diagnose CKD in children as accurately as serum creatinine and urea levels. This case-control study included 35 children with CKD and 28 healthy children as controls. Saliva and blood samples were collected for measurement of urea and creatinine levels. The urea and creatinine levels in serum and saliva in the CKD and control groups were compared using the independent samples Mann-Whitney U test. Correlations between the serum and salivary urea and creatinine levels were determined using Pearson's correlation coefficient. Receiver operating characteristic analysis was used to assess the diagnostic performance of salivary creatinine and cutoff values were identified. In the CKD group, the mean salivary creatinine level was 0.45 mg/dL and the mean salivary urea level was 0.11 mg/dL, versus 28.83 mg/dL and 21.78 mg/dL, respectively, in the control group. Stage 4 and 5 CKD patients had a mean salivary urea level of 31.35 mg/dL, as compared to 17.78 mg/dL in the control group. Serum urea and creatinine, and salivary creatinine were significantly higher in the CKD patients (regardless of disease stage) than in the controls (p serum and salivary creatinine. The area under the curve for salivary creatinine was 0.805. The cutoff value for salivary creatinine was 0.125 mg/dL, with a sensitivity of 82.9% and specificity of 78.6%.

In this study, we estimated the attendance to the second-trimester fetal malformation screening program. We also estimated the positive predictive value (PPV of prenatally assigned International Classification of Disease-10 diagnoses recorded in the Danish National Patient Registry (DNPR and the completeness of case registration. We used kidney anomalies as an example. Methods: We identified the proportion of all Danish live-born children from January 1, 2007 to December 31, 2012, who were scanned during the second trimester using the DNPR and the Civil Registration System. Details of all fetuses with specific kidney anomaly diagnoses according to the DNPR were retrieved. The PPV was estimated using the nationwide Astraia database of pregnancy medical charts or traditional medical charts, as gold standard. The completeness was assessed using the total number of cases estimated by the capture–recapture method. Results: Of 372,263 live born infants, 97.3% were scanned during the second trimester. We identified 172 fetuses in the DNPR. Of these, 149 had kidney anomalies according to Astraia or medical chart review, corresponding to a PPV of 87% (95% CI: 81%–91%. The estimated completeness was 43% (95% CI: 38%–49% for the DNPR and 75% (95% CI: 70%–79% for Astraia. Conclusion: Almost all live-born children were scanned during the second trimester in Denmark. However, low completeness may hamper the use of the DNPR for studies of prenatally detected

    Like many chronic illnesses, Behçet's disease (BD) has been reported to negatively affect the quality of life and mental health of the individuals diagnosed with this disease. This study aims to investigate the relationship between disease activity and depression and sleep quality in BD. Forty patients with BD and 30 healthy subjects (controls), aged 18-65, were included in this study, and all of the subjects enrolled in this study were assessed in terms of depression and sleep quality using the Beck depression index (BDI) and Pittsburg sleep quality index (PSQI). Additionally, the subjects with BD were also assessed using the Behçet's disease current activity form (BDCAF). It was determined that the depression and sleep quality scores were significantly higher in the BD group compared to those in the control group (p = 0.012 and p = 0.020, respectively), and in the BD group, significant positive correlations were determined between the BDCAF and depression and sleep quality scores (r = 0.559, p sleep quality, and providing medical support to those who need it, will contribute to the treatment and follow-up processes of BD.

    Tissue transglutaminase (tTG) autoantibodies decline after gluten-free diet in patients with coeliac disease. We tested the hypothesis that gluten-free diet-induced change in tTG autoantibody levels affects subsets of peripheral blood lymphocytes. Peripheral blood was obtained from 20 children with biopsy-proven active coeliac disease. Gluten-free diet was initiated and the children examined again after three and six months. tTG autoantibodies were measured in radioligand binding assays and lymphocyte subsets by flow cytometry. IgA-tTG levels at diagnosis, 2204 U/ml (median, range 113–24990), were reduced over six months to 76 U/ml (median, range 1–1261) (Pcoeliac disease. PMID:16542367

    Clinically, there is an increasing trend in using motivational interviewing as a counseling method to help clients with cardiovascular diseases to modify their unhealthy lifestyle in order to decrease the risk of disease occurrence. As motivational interviewing has gained increased attention, research has been conducted to examine its effectiveness. This review attempts to identify the best available evidence related to the effectiveness of motivational interviewing on lifestyle modification, physiological and psychological outcomes for clients at risk of developing or with established cardiovascular diseases. Systematic review of studies incorporating motivational interviewing in modifying lifestyles, improving physiological and psychological outcomes for clients at risk of or diagnosed with cardiovascular diseases. Major English and Chinese electronic databases were searched to identify citations that reported the effectiveness of motivational interviewing. The searched databases included MEDLINE, British Nursing Index, CINAHL Plus, PsycINFO, SCOPUS, CJN, CBM, HyRead, WanFang Data, Digital Dissertation Consortium, and so on. Two reviewers independently assessed the relevance of citations based on the inclusion criteria. Full texts of potential citations were retrieved for more detailed review. Critical appraisal was conducted by using the standardized critical appraisal checklist for randomized and quasi-randomized controlled studies from the Joanna Briggs Institute - Meta Analysis of Statistics Assessment and Review Instrument (JBI-MAStaRI). After eligibility screening, 14 articles describing 9 studies satisfied the inclusion criteria and were included in the analysis. Only certain outcomes in certain studies were pooled for meta-analysis because of the large variability of the studies included, other findings were presented in narrative form. For lifestyle modification, the review showed that motivational interviewing could be more effective than usual care on

    Full Text Available This study examines to what extent subjective illness concepts and symptoms of Turkish patients in Germany have changed over 40 years. Two groups of patients of Turkish origin from psychosomatic clinics in Germany took part in the study, the first group made up of 690 patients from the “first generation” of migrants and the second group comprising 350 patients from the “fourth generation“. The study was conducted using standardised interviews (The sociodemographic questionnaire,IPQ, COPE, BDI, SCL-90-R. Differences were found in essential aspects of subjective illness perception and illness coping strategies as well as in the diagnosis of psychological illness. The fourth generation of Turkish patients that were born and have grown up in Germany showed more problem-oriented behaviour regarding their coping strategies and less use of dysfunctional strategies for treatment than patients of the first generation. The findings of the present study are important for treating Turkish patients and patients of Turkish origin suffering from psychological disorders since they indicate that their disease perception, coping strategies and diagnoses undergo changes in the course of generations. Hitherto these differences were not taken into account in treatment; in the future we should be moving towards customised treatment in order to achieve better therapeutic effects.

    Knowing the identity of bacterial plant pathogens is essential to strategic and sustainable disease management in agricultural systems. This knowledge is critical for growers, diagnosticians, extension agents, and others dealing with crops. However, such identifications are linked to bacterial taxonomy, a complicated and changing discipline that depends on methods and information that are often not used by those who are diagnosing field problems. Modern molecular tools for fingerprinting and sequencing allow for pathogen identification in the absence of distinguishing or conveniently tested phenotypic characteristics. These methods are also useful in studying the etiology and epidemiology of phytopathogenic bacteria from epidemics, as was done in numerous studies conducted in California's Salinas Valley. Multilocus and whole-genome sequence analyses are becoming the cornerstones of studies of microbial diversity and bacterial taxonomy. Whole-genome sequence analysis needs to become adequately accessible, automated, and affordable in order to be used routinely for identification and epidemiology. The power of molecular tools in accurately identifying bacterial pathogenesis is therefore of value to the farmer, diagnostician, phytobacteriologist, and taxonomist.

    We aimed to analyze the construct and concurrent validity of the Rapid Visual Information Processing (RVP), Paired Associates Learning (PAL), Reaction Time (RTI), and Spatial Working Memory (SWM) tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB®). Inclusion criteria were checked in a first session. The CANTAB and additional pencil-and-paper tests were administered within 1 week. The participants (aged 69-96 years) were 137 Portuguese adults without neuropsychiatric diagnoses and 37 adults with mild-to-moderate Alzheimer's disease dementia. Comparisons were made between the CANTAB tests and between these tests and the Rey Complex Figure Test (RCFT), Verbal Fluency (VF) test, and some Wechsler Memory Scale-III and Wechsler Adult Intelligence Scale-III subtests. Most intra-test correlations were stronger than the CANTAB inter-test correlations. The RVP correlated more with VF animals (.44), the PAL with RCFT immediate recall (-.52), the RTI with RVP mean latency (.42), and the SWM with Spatial Span backward (-.39).

    Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease of a broad histological spectrum, characterized by the accumulation of triglycerides in more than 5% of hepatocytes in the absence of consuming alcohol in quantities harmful to the liver. The aim of our study was to determine the importance of anthropometric and laboratory parameters as well as metabolic syndrome (MS) for the diagnosis of NAFLD and to estimate their influence on the degree of liver steatosis as evaluated by ultrasound (US). The study included 86 participants, 55 of whom had fatty liver diagnosed by ultrasound and they comprised the study group. The control group consisted of 31 control subjects. During the course of hospitalization at the Clinic of Gastroenterology and Hepatology, Clinical Centre Niš, the patients had their anamnesis taken, and anthropometric measurements as well as biochemical blood analyses and abdominal ultrasound were performed. The patients with NAFLD had statistically higher values of body mass index (BMI), waist circumference (WC), systolic (SBP) and diastolic blood pressure (DBP), levels of alanin and aspartate aminotransferase (ALT, AST), gamma-glutamyl transpeptidase (GGT) (pobese patients. (BMI ≥ 30.0 kg/m2). The largest number of patients in the obesity group, 22 (40.00%) of them, had the first degree obesity (BMI from 30 kg/m2 to 34.99 kg/m2). The largest number of the NAFLD group patients - 23 (41.82%), had an ultrasound finding of grade 3 fatty liver, 20 patients (36.36%) had grade 2 and 12 (21.82%) grade 1 fatty liver. Kruskal-Wallis test and ANOVA analysis showed statistically significant differences between groups with different US grade for insulin, LDL-cholesterol, WC, BMI (pobesity, hypertension and DM type 2 (p<0.05). The results of our study have confirmed that a high percentage of patients with high risk factors (DM, MS, dyslipidemia, hypertension) have NAFLD.

    Taking into account the disturbances of lipid metabolism occurring in patients with demyelinating diseases, an expected finding was their increased basal lipolytic activity. We investigated 135 cases divided into 4 categories: 1. MS; 2. inflammatory diseases of the CNS; 3. cerebrovascular diseases and other diseases without any CNS organic involvements; 4. a group of absolutely healthy controls (blood donors). High values of plasmatic lipolytic activity were found in multiple sclerosis patients as compared with the other groups. They were probably due to the effect of a disturbance with an influence upon the basal lipoproteinlipase activity too. This influence is likely to refer to the stages of the process by which heparin releases lipoprotein-lipase from the capillary endothelium. Significant correlations between the clinical evolution of the disease and the values of lipolytic activity were pointed out. Measurement of this activity is a useful biochemical test in the diagnosis of multiple sclerosis.

The necropsy protocols and protocols of mailed in tissues from cattle under one year of age, submitted during 2000-2011 to LRD/UFPel for diagnosis, were reviewed. In 35.6% of the cases, the calves were of dairy breeds, 33.9% were beef calves, 18.3% were of mixed breed, and in 12.1% of the cases the breed was not informed. The organ systems most affected were the central nervous system (22.7%, digestive tract (18.6% and respiratory system (16.8%. The diagnoses were divided by age groups: 88 calves were 1-90 days of age, 42 were 4-6 months, 32 were 7-9 months, and 44 cattle were 10-12 months of age. The disease most often diagnosed in 1 to 90-day-old calves were pneumonia, malformations and encephalitis/meningoencephalitis, with 19.3%, 15.9% and 11.3% of cases respectively. In 4 to 6-month-old calves, pneumonia occurred in 16.5% of cases, and blackleg and diarrhea accounted for 7.1% of diagnoses each. In 7 to 9-month-old calves the most frequent diseases were pneumonia and tetanus with 9.3% of cases, and babesiosis and gastrointestinal parasitosis with 6.2% each. In 10 to 12-month-old calves, infection by BoHV-5 represented 13.6% of cases, and pneumonia, rabies and parasitosis was observed in 9% of cases each. Based on the results of this study it can be concluded that infectious diseases related to the respiratory system were important causes of mortality in calves of all ages until 12 months in the area of influence of LRD and

    A number of previous studies have identified antigen-presenting cells (APCs) as key targets of Ebola virus (EBOV), but the role of APCs in human Ebola virus disease (EVD) is not known. We have evaluated the phenotype and kinetics of monocytes, neutrophils, and dendritic cells (DCs) in peripheral blood of patients for whom EVD was diagnosed by the European Mobile Laboratory in Guinea. Acute EVD was characterized by reduced levels of circulating nonclassical CD16 + monocytes with a poor activation profile. In survivors, CD16 + monocytes were activated during recovery, coincident with viral clearance, suggesting an important role of this cell subset in EVD pathophysiology. © The Author 2016.

    Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases that have a remitting, relapsing nature. During relapse, they are treated with drugs and surgery. The present study was based on individual data from patients diagnosed with CD or UC at Herlev University...... Hospital, Copenhagen, Denmark, during 1991 to 1993. The data were aggregated over calendar years; for each year, the number of relapses and the number of surgical operations were recorded. Our aim was to estimate Markov models for disease activity in CD and UC, in terms of relapse and remission...... data and has good face validity. The disease activity model is less suitable for UC due to its transient nature through the presence of curative surgery...

    Objective To perform a systematic review of studies using remote physical activity monitoring in neurological diseases, highlighting advances and determining gaps. Methods Studies were systematically identified in PubMed/MEDLINE, CINAHL and SCOPUS from January 2004 to December 2014 that monitored physical activity for ≥24 hours in adults with neurological diseases. Studies that measured only involuntary motor activity (tremor, seizures), energy expenditure or sleep were excluded. Feasibility, findings, and protocols were examined. Results 137 studies met inclusion criteria in multiple sclerosis (MS) (61 studies); stroke (41); Parkinson's Disease (PD) (20); dementia (11); traumatic brain injury (2) and ataxia (1). Physical activity levels measured by remote monitoring are consistently low in people with MS, stroke and dementia, and patterns of physical activity are altered in PD. In MS, decreased ambulatory activity assessed via remote monitoring is associated with greater disability and lower quality of life. In stroke, remote measures of upper limb function and ambulation are associated with functional recovery following rehabilitation and goal-directed interventions. In PD, remote monitoring may help to predict falls. In dementia, remote physical activity measures correlate with disease severity and can detect wandering. Conclusions These studies show that remote physical activity monitoring is feasible in neurological diseases, including in people with moderate to severe neurological disability. Remote monitoring can be a psychometrically sound and responsive way to assess physical activity in neurological disease. Further research is needed to ensure these tools provide meaningful information in the context of specific neurological disorders and patterns of neurological disability. PMID:27124611

    To develop nursing diagnosis statements for the elderly based on the Activities of Living Model and on the International Classification for Nursing Practice. Descriptive and exploratory study, put in practice in two stages: 1) collection of terms and concepts that are considered clinically and culturally relevant for nursing care delivered to the elderly, in order to develop a database of terms and 2) development of nursing diagnosis statements for the elderly in primary health care, based on the guidelines of the International Council of Nurses and on the database of terms for nursing practice involving the elderly. 414 terms were identified and submitted to the content validation process, with the participation of ten nursing experts, which resulted in 263 validated terms. These terms were submitted to cross mapping with the terms of the International Classification for Nursing Practice, resulting in the identification of 115 listed terms and 148 non-listed terms, which constituted the database of terms, from which 127 nursing diagnosis statements were prepared and classified into factors that affect the performance of the elderly's activities of living - 69 into biological factors, 19 into psychological, 31 into sociocultural, five into environmental, and three into political-economic factors. After clinical validation, these statements can serve as a guide for nursing consultations with elderly patients, without ignoring clinical experience, critical thinking and decision-making.

    The purpose of this study is to compare and correlate US evaluation with clinical scores of the disease activity in patients with rheumatoid arthritis (RA) and concomitant fibromyalgia (FM). Ten patients diagnosed with RA according to the 2010 ACR/EULAR classification criteria and associated FM based on the ACR 1990 classification criteria and two control groups, one with RA (10 patients) and one with FM (10 patients), were included. Clinical assessment was performed and the disease activity scores were calculated. Synovial/tenosynovial hypertrophy, fluid collections in grey scale (GS), and Power Doppler (PD) US assessed by US in the 28 joints included in the disease activity score 28 (DAS28). GS US score and PD US scores were correlated with DAS28 only in patients with RA (Pearson r coefficients 0.3 and 0.5). Mean DAS28 score was significantly higher in the RA/FM group, compared to RA and FM (5.6 versus 4.6 versus 4.5, respectively). Patients with RA/FM had similar median US scores to RA patients, while in FM group significantly lower median US scores were detected (16 versus 9.5 versus 0 for GS US and 3.5 versus 1.5 versus 0 for PD US, respectively). Disease activity scores should be interpreted with caution in patients with RA and FM. When available, US should be used to guide treatment decisions in patients with RA and FM.

    Among Swedish children of 0-12 years old, we investigated various food allergy-related exposures associated with health-related quality of life using a food allergy-specific questionnaire among children allergic to the staple foods cow's milk, hen's egg and/or wheat, and contextualised worse food allergy-associated health-related quality of life using a generic questionnaire versus controls. In total, 85 children with objectively diagnosed allergy to the staple foods were included as cases, and 94 children matched for age and sex were included as controls. We administered a food allergy-specific parent-completed questionnaire originally developed by EuroPrevall to cases only, and a generic health-related quality of life questionnaire (EuroQol Health Questionnaire, 5 Dimensions; EQ 5-D); to both cases and controls. Hen's egg was the most common offending staple food, affecting 76% of cases. Approximately 7% of cases were allergic to all three staple foods.

    The aim of this study was to investigate differences in amino-terminal proB-type natriuretic peptide (NT-proBNP) levels in the cord blood of neonates according to the type of congenital heart disease (CHD) and to evaluate the usefulness of NT-proBNP as a prognostic marker. We included 76 neonates with prenatally diagnosed CHD and 45 controls without CHD. Neonates were classified into five groups based on echocardiographic findings. The levels of NT-proBNP in the cord blood were examined and analyzed according to the neonatal outcomes. The levels of NT-proBNP were significantly elevated in the cord blood of neonates with CHD compared with that in the cord blood of controls. The levels of NT-proBNP in the group with right ventricular outflow tract obstruction without a ventricular septal defect were significantly increased compared to that in the other groups. The neonates that required acute surgical correction had higher levels of NT-proBNP in the cord blood, though they were not statistically significant. Meanwhile, NT-proBNP levels in the cord blood of neonates with functional single ventricle were significantly higher than that in the cord blood of those with functional biventricles. Significant differences in the levels of NT-proBNP between survivors and nonsurvivors were observed within 1 year of birth. In this study, we found that the levels of NT-proBNP in the cord blood of neonates with CHD were higher than the levels in controls. This finding was striking in the group with right ventricular outflow tract obstruction, and it was associated with surgery for functional single ventricle and 1-year survival.

    Periostin is an extracellular matrix protein that is implicated in the biology of normal bone remodeling and in different cancer cell growth and metastasis. However, there is no information on the role of periostin in multiple myeloma (MM). Thus, we evaluated periostin in six myeloma cell lines in vitro; in the bone marrow plasma and serum of 105 newly diagnosed symptomatic MM (NDMM) patients and in the serum of 23 monoclonal gammopathy of undetermined significance (MGUS), 33 smoldering MM (SMM) patients, 30 patients at the plateau phase post-first-line therapy, 30 patients at first relapse and 30 healthy controls. We found high levels of periostin in the supernatants of myeloma cell lines compared with ovarian cancer cell lines that were not influenced by the incubation with the stromal cell line HS5. In NDMM patients the bone marrow plasma periostin was almost fourfold higher compared with the serum levels of periostin and correlated with the presence of fractures and of diffuse magnetic resonance imaging pattern of marrow infiltration. Serum periostin was elevated in NDMM patients compared with healthy controls, MGUS and SMM patients and correlated with advanced disease stage, high lactate dehydrogenase, increased activin-A, increased bone resorption and reduced bone formation. Patients at first relapse had also elevated periostin compared with healthy controls, MGUS and SMM patients, while even patients at the plateau phase had elevated serum periostin compared with healthy controls. These results support an important role of periostin in the biology of myeloma and reveal periostin as a possible target for the development of antimyeloma drugs.

    This study describes clinical characteristics, prognostic factors, and quality of life in patients with newly diagnosed (incident) digital ulcers (DU). Observational cohort study of 189 consecutive SSc patients with incident DU diagnosis identified from the EUSTAR database (22 centres in 10 countries). Data were collected from medical charts and during one prospective visit between 01/2004 and 09/2010. Median age at DU diagnosis was 51 years, majority of patients were female (88%), and limited cutaneous SSc was the most common subtype (61%). At incident DU diagnosis, 41% of patients had one DU and 59% had ≥2 DU; at the prospective visit 52% had DU. Pulmonary arterial hypertension (PAH) and multiple DU at diagnosis were associated with presence of any DU at the prospective visit (odds ratios: 4.34 and 1.32). During the observation period (median follow-up was 2 years) 127 patients had ≥1 hospitalisation. The event rate of new DU per person-year was 0.66, of DU-associated complications was 0.10, and of surgical or diagnostic procedures was 0.12. At the prospective visit, patients with ≥1 DU reported impairment in daily activities by 57%, those with 0 DU by 37%. The mean difference between patients with or without DU in the SF-36 physical component was 2.2, and in the mental component 1.4. DU patients were not routinely prescribed endothelin receptor antagonists or prostanoids. This real world cohort demonstrates that DU require hospital admission, and impair daily activity. PAH and multiple DU at diagnosis were associated with future occurrence of DU.

    Women who smoke at breast cancer diagnosis have higher risk of breast cancer-specific and all-cause mortality than nonsmokers; however, differences by ethnicity or prognostic factors and risk for noncancer mortality have not been evaluated. We examined associations of active and passive smoke exposure with mortality among Hispanic (n = 1020) and non-Hispanic white (n = 1198) women with invasive breast cancer in the Breast Cancer Health Disparities Study (median follow-up of 10.6 years). Risk of breast cancer-specific (HR = 1.55, 95% CI = 1.11-2.16) and all-cause (HR = 1.68, 95% CI = 1.30-2.17) mortality was increased for current smokers, with similar results stratified by ethnicity. Ever smokers had an increased risk of noncancer mortality (HR = 1.68, 95% CI = 1.12-2.51). Associations were strongest for current smokers who smoked for 20 years or more were postmenopausal, overweight and/or obese, or reported moderate and/or high alcohol consumption; however, interactions were not significant. Breast cancer-specific mortality was increased two fold for moderate and/or high recent passive smoke exposure among never smokers (HR = 2.12, 95% CI = 1.24-3.63). Findings support associations of active-smoking and passive-smoking diagnosis with risk of breast cancer-specific and all-cause mortality and ever smoking with noncancer mortality, regardless of ethnicity, and other factors. Smoking is a modifiable lifestyle factor and effective smoking cessation, and maintenance programs should be routinely recommended for women with breast cancer. Copyright © 2015 Elsevier Inc.

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

    Background As the number of people with Internet access rises, so does the use of the Internet as a potentially valuable source for health information. Insight into patient use of this information and its correlates over time may reveal changes in the digital divide based on patient age and education. Existing research has focused on patient characteristics that predict Internet information use and research on treatment context is rare. Objective This study aims to (1) present data on the proportion of newly diagnosed breast cancer patients treated in German breast centers from 2007 to 2013 who used the Internet for information on their disease, (2) look into correlations between Internet utilization and sociodemographic characteristics and if these change over time, and (3) determine if use of Internet information varies with the hospitals in which the patients were initially treated. Methods Data about utilization of the Internet for breast cancer–specific health information was obtained in a postal survey of breast cancer patients that is conducted annually in Germany with a steady response rate of 87% of consenting patients. Data from the survey were combined with data obtained by hospital personnel (eg, cancer stage and type of surgery). Data from 27,491 patients from 7 consecutive annual surveys were analyzed for this paper using multilevel regression modeling to account for clustering of patients in specific hospitals. Results Breast cancer patients seeking disease-specific information on the Internet increased significantly from 26.96% (853/3164) in 2007 to 37.21% (1485/3991) in 2013. Similar patterns of demographic correlates were found for all 7 cohorts. Older patients (≥70 years) and patients with digital divide based on age and education. Conclusions Use of the Internet for health information is on the rise among breast cancer patients. The strong age- and education-related differences raise the question of how relevant information can be adequately

    Intermittent claudication (IC) is the most common clinical manifestation of atherosclerotic peripheral arterial disease. Exercise training plays a major role in treating patients with IC. Regular exercise increases functional walking capacity, reduces cardiovascular mortality and improves quality of life. This seems to be achieved by: favorable effect on cardiovascular risk factors, anti-inflammatory effect, increased collateral blood flux, improved rheology profile, endothelial function, fibrinolysis, and muscular metabolism. However, exact mechanisms underlying beneficial effect of exercise remain largely unknown. Exercise modalities will be discussed in this article.

    It was studied the 131 I-labelled albumin metabolism in fourteen female patients with rheumatoid arthritis. The half-life of distribution was increased while the turnover half-life and turnover rate was within normal limits. These results led to assume that synthesis and catabolism may not change this disease, not being the responsible mechanism of hypoalbuminemia. Hypoalbuminemia would appear as compensatory mechanism in view of other protein alterations, as hypergammaglobulinemia, without changes of stabilizing and metabolic properties of albumin, perhaps due to albumin molecular alterations [pt

    Full Text Available Introduction & Objective: MS is the most common disabling neurological disorder. Identifying new active MS plaques at the onset and clinical status and faster onset of treatment as well as evaluating the response to treatment is important and MRI with contrast is the best indicator for these measures. Materials & Methods: This study was cross-sectional including 62 patients with diagnosed MS. Whose clinical symptoms suggested the recurrence of MS. They were referred to the radiol-ogy department to undergo brain MRI with injection for the diagnosis of active plaques by a neurologist,The Data were analyzed using statistical tests and SPSS 21 software. Results: Based on the sequences of post contrast T1, pre contrast MTC and post contrast MTC 74, 272 and 271 plaques were respectively discovered. Detection of active MS plaques on T1 sequences after injection were in poor accordance and had significant difference with MTC before and after injection. Moreover, detection of active MS plaques on MTC sequences be-fore injection were in good accordance and did not show significant difference with MTC se-quences after injection. Conclusion: Based on these results, it seems that the purpose of MRI in MS patients is deter-mining the amount of active plaques. Sequences of pre contrast and post contrast MTC are significantly more than sequences of post contrast T1. Therefore, using sequences of MTC can be helpful in MRI.

    Full Text Available AIM: To determine whether QuantiFERON®-TB Gold In-Tube (QFT can contribute to the diagnosis of active tuberculosis (TB in children in a high-burden setting and to assess the performance of QFT and tuberculin skin test (TST in a prospective cohort of TB suspect children compared to adults with confirmed TB in Tanzania. METHODS: Sensitivity and specificity of QFT and TST for diagnosing active TB as well as indeterminate QFT rates and IFN-γ levels were assessed in 211 TB suspect children in a Tanzanian district hospital and contrasted in 90 adults with confirmed pulmonary TB. RESULTS: Sensitivity of QFT and TST in children with confirmed TB was 19% (5/27 and 6% (2/31 respectively. In adults sensitivity of QFT and TST was 84% (73/87 and 85% (63/74. The QFT indeterminate rate in children and adults was 27% and 3%. Median levels of IFN-γ were lower in children than adults, particularly children <2 years and HIV infected. An indeterminate result was associated with age <2 years but not malnutrition or HIV status. Overall childhood mortality was 19% and associated with an indeterminate QFT result at baseline. CONCLUSION: QFT and TST showed poor performance and a surprisingly low sensitivity in children. In contrast the performance in Tanzanian adults was good and comparable to performance in high-income countries. Indeterminate results in children were associated with young age and increased mortality. Neither test can be recommended for diagnosing active TB in children with immature or impaired immunity in a high-burden setting.

    Chronic obstructive pulmonary disease (COPD) patients are at risk for asymptomatic peripheral arterial disease (PAD) because smoking is a risk factor for COPD and PAD. The objectives of this study were to determine the proportion of COPD patients with asymptomatic PAD and to investigate whether the estimated risk of asymptomatic PAD in subjects with COPD differs using resting and exercise ankle-brachial index (ABI) in smokers. Using a cross-sectional study design, consecutive smokers > 50 years old were recruited over 2 months from the inpatient units and the outpatient clinics. Subjects previously diagnosed with PAD, unstable angina, recent (< 3 months) myocardial infarction or abdominal, intracranial, eye or lung surgery, and palliative care patients were excluded. Vascular risk factors, ABI (supine and post-3-minute walk supine), self-reported PAD symptoms, and spirometry were obtained. Two measurements of systolic blood pressure on all limbs were obtained using a sphygmomanometer and a Doppler ultrasound, and the ABI was calculated. Data were expressed as means ± standard deviation (SD). Dichotomous outcomes were assessed using Chi-square statistics; P-values of < 0.05 were considered significant. Thirty patients with no previous diagnosis of PAD were recruited. Mean age was 67.7 years (SD: 10.5). Overall, 21 subjects (70%) had spirometry-proven COPD. Significant ABI for PAD (< 0.9) was seen in 7/21 COPD (33.5%) and 0/9 non-COPD subjects in the supine resting position (P = 0.07), and in 9/21 COPD (42.9%) vs. 0/9 non-COPD subjects after exercise (P = 0.03). A significant proportion of patients with spirometry-proven COPD screened positive for asymptomatic PAD after exercise. Resting ABI may not be very sensitive to diagnose asymptomatic PAD in COPD subjects. ABI may be a reliable, sensitive and practical screening tool to assess cardiovascular risk in COPD patients. Future large-scale studies are required to confirm this finding.

    To design a fuzzy expert system to help detect and diagnose the severity of diabetic neuropathy. The research was completed in 2014 and consisted of two main phases. In the first phase, the diagnostic parameters were determined based on the literature review and by investigating specialists' perspectives ( n = 8). In the second phase, 244 medical records related to the patients who were visited in an endocrinology and metabolism research centre during the first six months of 2014 and were primarily diagnosed with diabetic neuropathy, were used to test the sensitivity, specificity, and accuracy of the fuzzy expert system. The final diagnostic parameters included the duration of diabetes, the score of a symptom examination based on the Michigan questionnaire, the score of a sign examination based on the Michigan questionnaire, the glycolysis haemoglobin level, fasting blood sugar, blood creatinine, and albuminuria. The output variable was the severity of diabetic neuropathy which was shown as a number between zero and 10, had been divided into four categories: absence of the disease, (the degree of severity) mild, moderate, and severe. The interface of the system was designed by ASP.Net (Active Server Pages Network Enabled Technology) and the system function was tested in terms of sensitivity (true positive rate) (89%), specificity (true negative rate) (98%), and accuracy (a proportion of true results, both positive and negative) (93%). The system designed in this study can help specialists and general practitioners to diagnose the disease more quickly to improve the quality of care for patients.

    Physical activity, by definition, is any skeletal muscle body movement that results in energy expenditure. In the last few decades, a plethora of scientific evidences have accumulated and confirmed the beneficial role of physical activity as a modifiable risk factor for a wide variety of chronic diseases including cardiovascular diseases (CVDs), diabetes mellitus and cancer, among others. Autoimmune diseases are a heterogeneous group of chronic diseases, which occur secondary to loss of self-antigen tolerance. With the advent of biological therapies, better outcomes have recently been noted in the management of autoimmune diseases. Nonetheless, recent research highlights the salient role of modifiable behaviors such as physical inactivity on various aspects of the immune system and autoimmune diseases. Physical activity leads to a significant elevation in T-regulatory cells, decreased immunoglobulin secretion and produces a shift in the Th1/Th2 balance to a decreased Th1 cell production. Moreover, physical activity has been proven to promote the release of IL-6 from muscles. IL-6 released from muscles functions as a myokine and has been shown to induce an anti-inflammatory response through IL-10 secretion and IL-1β inhibition. Physical activity has been shown to be safe in most of autoimmune diseases including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), multiple sclerosis (MS), inflammatory bowel diseases (IBD), as well as others. Additionally, the incidence of RA, MS, IBD and psoriasis has been found to be higher in patients less engaged in physical activity. As a general trend, patients with autoimmune diseases tend to be less physically active as compared to the general population. Physically active RA patients were found to have a milder disease course, better cardiovascular disease (CVD) profile, and improved joint mobility. Physical activity decreases fatigue, enhances mood, cognitive abilities and mobility in patients with MS. In SLE

Review of clinical patient characteristics, cardiovascular disease and risk factors, in the year of diabetes diagnosis. Patients without any glycaemia recorded before diagnostic were excluded. Logistic regression was done to identify the variables associated to cardiovascular events. Results: From 598 cases of diabetes diagnosed, 487 with previous glycaemia were included for the analysis (mean age [SD], 60.4 [10.9]; 53% women. The prevalence of cardiovascular risk factors was: obesity 61.1%, hypertension 71.9%, hypercholesterolemia 52%, hypertriglyceridemia 35.3% and present or previous smoking habit (24 and 16,6%. 96.9% of them presented at least one of the studied cardiovascular risk factors and 53.4% three or more. 78 patients (16%; CI95%: 12.8-19.3 had cardiovascular disease before or during the first year of diagnosis (men 21.4% and women 11.2%. The prevalence of cardiovascular disease increased progressively with the number of cardiovascular risk factors. The significant predictive variables of cardiovascular disease (logistic regression were: age >55 years (OR=2.91; CI95%: 1.46-5.80, smoking habit (OR=2.28; CI95%: 1.15-4.51 and HbA1c >7% (OR=1.8; CI95%: 1.1-3.1. Conclusions: A high prevalence of cardiovascular disease and cardiovascular risk factors at diabetes diagnosis was observed. Age, smoking habit and elevated glycated haemoglobin were the variables related to cardiovascular disease.

    People with ankylosing spondylitis (AS) typically experience episodic exacerbations, but the extent to which they subsequently experience a sustained reduction in disease markers below recognized thresholds for active disease is unclear. To investigate changes in, and associations between, disease markers over 18 months in people with active AS. Within a cohort of 89 participants with AS, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores of 4 or higher were used to identify those with active disease. Standard assessment tools were used to monitor participants prospectively at four consecutive six-monthly intervals. Participants received standard treatments but none received anti-tumor necrosis factor-alpha (TNFalpha) medication during the study. The median age of the cohort was 50 years (inter-quartile range [IQR] 38.5-55.5), the median age of disease onset was 25 years (IQR 18-33) and the median disease duration was 18 years (IQR 13-27). Forty-seven (53%) participants had a BASDAI score of 4 or higher on the first assessment, of whom 45 (51%) scored 4 or higher on all subsequent assessments. Furthermore, 38 (43%) and 16 (18%) participants scored BASDAI 5 or 6, respectively, or higher, throughout. BASDAI scores correlated strongly with Bath Ankylosing Spondylitis Functional Index (BASFI) scores. Compared with 19 (21%) participants whose BASDAI scores were consistently below 4 throughout, participants with persistently high BASDAI scores showed higher scores for anxiety and depression, and some evidence of functional deterioration during the study period. In this cohort, disease markers in most people with active AS were sustained above the standard threshold for active disease. This has important implications for planning care pathways and for optimal utilization of anti-TNFalpha treatment.

    Summary Background Contrast-enhanced ultrasound (CEUS) is a recent non-invasive modality, which may partially replace currently used techniques (endoscopy, CT enterography and MR enterography) in the diagnostics and assessment of Crohn’s disease (CD). The aim of the study was to analyze early experience in the use of CEUS for the measurement of activity and staging of CD. Material/Methods Eleven patients previously diagnosed with CD were included in the study. They underwent contrast-enhanced ultrasonography (SonoVue, Bracco), low-dose CT enterography (LDCTE), assessment of laboratory markers of inflammation and clinical CD activity index (CDAI). Contrast enhancement was evaluated using a semi-quantitative method and a quantitative method that included measurement of peak enhancement (PE), enhancement curve rise time (RT) and wash-in-rate (WiR). Results Ileal wall thickening was observed in all patients. Semi-quantitative method was used to observe CD activity in CEUS in 10 cases that perfectly matched LDCTE findings. There was a moderate positive correlation between PE and CDAI (r=0.65, p<0.001). There was no significant relationship between perfusion parameters and laboratory markers of inflammation. Conclusions CEUS is a promising modality for non-invasive assessment of pathologic ileal vascularization in the course of Crohn’s disease.

    Contrast-enhanced ultrasound (CEUS) is a recent non-invasive modality, which may partially replace currently used techniques (endoscopy, CT enterography and MR enterography) in the diagnostics and assessment of Crohn's disease (CD). The aim of the study was to analyze early experience in the use of CEUS for the measurement of activity and staging of CD. Eleven patients previously diagnosed with CD were included in the study. They underwent contrast-enhanced ultrasonography (SonoVue, Bracco), low-dose CT enterography (LDCTE), assessment of laboratory markers of inflammation and clinical CD activity index (CDAI). Contrast enhancement was evaluated using a semi-quantitative method and a quantitative method that included measurement of peak enhancement (PE), enhancement curve rise time (RT) and wash-in-rate (WiR). Ileal wall thickening was observed in all patients. Semi-quantitative method was used to observe CD activity in CEUS in 10 cases that perfectly matched LDCTE findings. There was a moderate positive correlation between PE and CDAI (r=0.65, p<0.001). There was no significant relationship between perfusion parameters and laboratory markers of inflammation. CEUS is a promising modality for non-invasive assessment of pathologic ileal vascularization in the course of Crohn's disease.

    The main health problem of the Polish population is posed by cardiovascular diseases (CDVD), coronary artery disease (CAD) in particular. Respectively higher physical activity linked with energy expenditure of at least 1000 kcal/week may significantly reduce the risk of CAD development. The protective effect of exercise applies not only to persons from high-risk groups and with diagnosed chronic diseases that increase the risk of the incidence of atherosclerosis and its complications, but also to healthy individuals. The aim of this study was to evaluate the usability of the Seven-Day Physical Activity Recall (SDPAR) and International Physical Activity Questionnaire (IPAQ) in research on the correlation between physical activity and risk factors of cardiovascular diseases. A screening survey, conducted in 2012, included students (n = 340) of the Division of the Academy of Physical Education in Biała Podlaska, aged 18-29 years. Total cholesterol, triglycerides and glucose levels were analyzed, and arterial blood pressure and heart rate were measured. The physical activity of the students was estimated using IPAQ and SDPAR questionnaires. The effect of physical activity on the biochemical blood markers, arterial blood pressure and heart rate was analyzed in groups differing in weekly energy expenditure (WEE). Along with increasing WEE values, calculated with IPAQ and SDPAR questionnaires, tangible descending tendencies were observed in cholesterol concentration in both genders. Significant differences were demonstrated in mean values of the resting heart rate between terciles of women ranked according to the increasing WEE values calculated using IPAQ (p blood lipid profile and in mean resting heart rate values as affected by the higher energy expenditure. The IPAQ and SDPAR may be applied to assess the level of physical activity; however the SDPAR seems to be a more useful tool in CDVD prevention screening.

    Full Text Available Lupus nephritis (LN is among the most serious complications of systemic lupus erythematosus (SLE, which causes significant morbidity and mortality. Renalase is a novel, kidney-secreted cytokine-like protein that promotes cell survival. Here, we aimed to investigate the relationship of serum renalase levels with LN and its role in the disease progression of LN.For this cross-sectional study, 67 LN patients and 35 healthy controls were enrolled. Seventeen active LN patients who received standard therapies were followed up for six months. Disease activity was determined by the SLE Disease Activity-2000 (SLEDAI-2K scoring system and serum renalase amounts were determined by ELISA. Predictive value of renalase for disease activity was assessed. Furthermore, the expression of renalase in the kidneys of patients and macrophage infiltration was assessed by immunohistochemistry.Serum renalase amounts were significantly higher in LN patients than in healthy controls. Moreover, patients with proliferative LN had more elevated serum renalase levels than Class V LN patients. In proliferative LN patients, serum renalase levels were significantly higher in patients with active LN than those with inactive LN. Serum renalase levels were positively correlated with SLEDAI-2K, 24-h urine protein excretion, ds-DNA and ESR but inversely correlated with serum albumin and C3. Renalase amounts decreased significantly after six-months of standard therapy. The performance of renalase as a marker for diagnosis of active LN was 0.906 with a cutoff value of 66.67 μg/ml. We also observed that the amount of renalase was significantly higher in glomerular of proliferative LN along with the co-expression of macrophages.Serum renalase levels were correlated with disease activity in LN. Serum renalase might serve as a potential indicator for disease activity in LN. The marked increase of glomerular renalase and its association with macrophages suggest that it might play an

  9. Identification and Characterization of Novel Variations in Platelet G-Protein Coupled Receptor (GPCR Genes in Patients Historically Diagnosed with Type 1 von Willebrand Disease.

    Directory of Open Access Journals (Sweden)

    Full Text Available The clinical expression of type 1 von Willebrand disease may be modified by co-inheritance of other mild bleeding diatheses. We previously showed that mutations in the platelet P2Y12 ADP receptor gene (P2RY12 could contribute to the bleeding phenotype in patients with type 1 von Willebrand disease. Here we investigated whether variations in platelet G protein-coupled receptor genes other than P2RY12 also contributed to the bleeding phenotype. Platelet G protein-coupled receptor genes P2RY1, F2R, F2RL3, TBXA2R and PTGIR were sequenced in 146 index cases with type 1 von Willebrand disease and the potential effects of identified single nucleotide variations were assessed using in silico methods and heterologous expression analysis. Seven heterozygous single nucleotide variations were identified in 8 index cases. Two single nucleotide variations were detected in F2R; a novel c.-67G>C transversion which reduced F2R transcriptional activity and a rare c.1063C>T transition predicting a p.L355F substitution which did not interfere with PAR1 expression or signalling. Two synonymous single nucleotide variations were identified in F2RL3 (c.402C>G, p.A134 =; c.1029 G>C p.V343 =, both of which introduced less commonly used codons and were predicted to be deleterious, though neither of them affected PAR4 receptor expression. A third single nucleotide variation in F2RL3 (c.65 C>A; p.T22N was co-inherited with a synonymous single nucleotide variation in TBXA2R (c.6680 C>T, p.S218 =. Expression and signalling of the p.T22N PAR4 variant was similar to wild-type, while the TBXA2R variation introduced a cryptic splice site that was predicted to cause premature termination of protein translation. The enrichment of single nucleotide variations in G protein-coupled receptor genes among type 1 von Willebrand disease patients supports the view of type 1 von Willebrand disease as a polygenic disorder.

    Determining inflammatory activity is crucial for assessing disease activity and for tailoring therapy in patients with Crohn׳s disease (CD). This study aimed to evaluate adipocytokine levels in patients with CD and to determine whether they can serve as surrogate markers for disease activity. Serum samples and information regarding the clinical features of patients in the CD Network Project registry were collected from March 2009 to February 2012. Patients with CD and disease duration of at least 2 years were enrolled in this study. Fasting serum leptin, adiponectin, obestatin and ghrelin levels were measured, and their correlation with clinical features of the patients was analyzed. Serum adipocytokine levels were evaluated according to disease activity as determined by CD activity index score. A total of 153 patients with CD were included. Serum ghrelin levels negatively correlated with patient age (P = 0.041) and age at diagnosis (P = 0.017), and positively correlated with C-reactive protein (CRP) levels (P = 0.017). Multiple regression analysis showed that serum ghrelin levels were related only to CRP levels (P = 0.032). Like ghrelin, serum leptin levels were also related to CRP levels (P disease locations or behaviors. Serum ghrelin levels were significantly lower in patients with CD with a history of surgery than in those without (P = 0.007). Serum ghrelin and leptin levels may be useful as surrogate markers for disease activity in patients with CD. Copyright © 2017 Southern Society for Clinical Investigation. Published by Elsevier Inc.

    Type 2 diabetes is known to cause endothelial activation resulting in the secretion of von Willebrand factor (VWF). We have shown that levels of VWF in a glycoprotein Ib-binding conformation are increased in specific clinical settings. The aim of the current study is to investigate whether active VWF levels increase during aging and the development of diabetes within the population of patients suffering from type 2 diabetes. Patients and controls were divided into two groups based on age: older and younger than 60 years of age. VWF antigen, VWF propeptide, VWF activation factor and total active VWF were measured. Patients older than 60 years of age had increased levels of total active VWF, VWF activation factor and VWF propeptide compared to younger patients and controls. All measured VWF parameters were associated with age in diabetic patients. Total active VWF and VWF propeptide correlated with the period of being diagnosed with diabetes. Regression analyses showed that especially the VWF activation factor was strongly associated with diabetes in patients older than 60 years of age. In conclusion, we found that the conformation of VWF could be involved in the disease process of diabetes and that the VWF in a glycoprotein Ib-binding conformation could play a role as risk marker during the development of diabetes in combination with an increase in age. Our study shows that the active quality of VWF was more important than the quantity.

    Impairment of sleep quality is common in patients with inflammatory bowel diseases (IBDs) (eg, Crohn's disease [CD] and ulcerative colitis [UC]), even during clinical remission. Sleep impairment can activate inflammatory pathways. Few prospective studies have examined the role of sleep disturbance on risk of relapse in IBD. We analyzed data from 3173 patients with IBD (1798 in clinical remission at baseline) participating in the Crohn's and Colitis Foundation of America Partners study, a longitudinal, Internet-based cohort. Sleep disturbance was measured using a subset of questions from the Patient Reported Outcomes Measurement Information Systems sleep disturbance questionnaire. Disease activity was assessed using the short Crohn's Disease Activity Index and the simple clinical colitis activity index for CD and UC, respectively. Logistic regression was used to identify predictors of sleep quality and examine the effect of sleep quality at baseline among patients in remission on risk of active disease at 6 months. Disease activity, depression, female sex, smoking, and use of corticosteroids or narcotics were associated with sleep disturbance at enrollment. Among 1291 patients whose CD was in remission at baseline, those with impaired sleep had a 2-fold increase in risk of active disease at 6 months (adjusted odds ratio, 2.00; 95% confidence interval, 1.45-2.76); however, no effect was observed in patients with UC (odds ratio, 1.14; 95% confidence interval, 0.75-1.74). These findings persisted in a number of sensitivity analyses. Sleep disturbance was associated with an increased risk of disease flares in CD but not UC. These findings indicate that the evaluation and treatment of sleep disturbance in patients with CD might improve outcomes. Copyright © 2013 AGA Institute. Published by Elsevier Inc.

    To assess the influence of subjective word-finding difficulty on degree of engagement in social leisure activities among individuals with Alzheimer's disease (AD). Analysis of data collected from the second cohort of the Multicenter Study of Predictors of Disease Course in Alzheimer's disease. Four study sites in the United States and France. Individuals diagnosed with mild to moderate AD (N = 236). On separate questionnaires, participants were asked to 1) report whether they had trouble finding the right word when speaking (subjective word-finding difficulty) and 2) rate their frequency and enjoyment of social and nonsocial leisure activities. Objective language measures included object naming and verbal fluency. Measures of dependence, depression, cognitive status, age, sex, and education were also included as covariates in regression analyses. Fifty-two percent of the sample reported word-finding difficulty, and subjective complaints were correlated with poorer verbal fluency scores. Subjective word-finding difficulty was selectively related to social but not nonsocial activity measures. Endorsers of word-finding difficulty reported less frequency and enjoyment of social leisure activities, controlling for effects of covariates and objective word-finding ability. In contrast, lower engagement in nonsocial activities was associated with older age and higher depression scores but not with word-finding complaints. Caregivers' reports of study participants' activities corroborated these results. Individuals with AD who are aware of increasing word-finding failures are less likely to participate in and enjoy socially oriented leisure activities. This finding may have significant implications for clinical and health outcomes in AD. Failure to evaluate subjective language complaints could result in social withdrawal symptoms, threatening the individual's quality of life and increasing caregiver burden. Reduced social interaction may ultimately exacerbate language

    Sleep dysfunction is a highly prevalent condition that has long been implicated in accelerating disease states characterized by having an inflammatory component such as systemic lupus erythematosus, HIV, and multiple sclerosis. Inflammatory bowel disease (IBD) is a chronic, debilitating disease that is characterized by waxing and waning symptoms, which are a direct result of increased circulating inflammatory cytokines. Recent studies have demonstrated sleep dysfunction and the disruption of the circadian rhythm to result in an upregulation of inflammatory cytokines. Not only does this pose a potential trigger for disease flares but also an increased risk of malignancy in this subset of patients. This begs to question whether or not there is a therapeutic role of sleep cycle and circadian rhythm optimization in the prevention of IBD flares. Further research is needed to clarify the role of sleep dysfunction and alterations of the circadian rhythm in modifying disease activity and also in reducing the risk of malignancy in patients suffering from IBD.

    Improved understanding of the role of inflammation in tendon disease is required to facilitate therapeutic target discovery. We studied supraspinatus tendons from patients experiencing pain before and after surgical subacromial decompression treatment. Tendons were classified as having early, intermediate or advanced disease and inflammation was characterized through activation of pathways mediated by Interferon, NF-κB, glucocorticoid receptor and STAT-6. Inflammation signatures revealed expression of genes and proteins induced by Interferon and NF-κB in early stage disease and genes and proteins induced by STAT-6 and glucocorticoid receptor activation in advanced stage disease. The pro-resolving proteins FPR2/ALX and ChemR23 were increased in early stage disease compared to intermediate-advanced stage disease. Patients who were pain-free post-treatment had tendons with increased expression of CD206 and ALOX15 mRNA compared to tendons from patients who continued to experience pain post-treatment, suggesting that these genes and their pathways may moderate tendon pain. Stromal cells from diseased tendons cultured in vitro showed increased expression of NF-κB and Interferon target genes after treatment with lipopolysaccharide or IFNγ compared to stromal cells derived from healthy tendons. We identified 15-epi Lipoxin A4, a stable lipoxin metabolite derived from aspirin treatment, as potentially beneficial in the resolution of tendon inflammation. PMID:26511510

    Periodontal disease in dogs is highly prevalent but can only be accurately diagnosed by performing an anesthetized oral examination with periodontal probing and dental radiography. In this study, 114 dogs had a visual awake examination of the oral cavity and were administered an oral-fluid thiol-detection test prior to undergoing a a full-mouth anesthetized oral examination and digital dental radiographs. The results show the visual awake examination underestimated the presence and severity of active periodontal disease. The thiol-detection test was superior to the visual awake examination at detecting the presence and severity of active periodontal disease and was an indicator of progression toward alveolar bone loss. The thiol-detection test detected active periodontal disease at early stages of development, before any visual cues were present, indicating the need for intervention to prevent periodontal bone loss. Early detection is important because without intervention, dogs with gingivitis (active periodontal disease) progress to irreversible periodontal bone loss (stage 2+). As suggested in the current AAHA guidelines, a thiol-detection test administered in conjunction with the visual awake examination during routine wellness examinations facilitates veterinarian-client communication and mitigates under-diagnosis of periodontal disease and underutilization of dental services. The thiol-detection test can be used to monitor the periodontal health status of the conscious patient during follow-up examinations based on disease severity.

    Takayasu arteritis (TA) is a rare, sporadic and chronic inflammatory arteritis, which predominantly affects the aorta and its branches. Diagnosis can be difficult and there are limitations to the current diagnostic work-up. By detecting areas of active glucose metabolism present in active vasculitis, imaging with fluorine-18 fluorodeoxyglucose positron emission tomography ( 18 F-FDG PET) could potentially have a role in the management of TA. Our aim was to assess this role by reviewing 28 18 F-FDG PET scans performed on 18 patients suspected of having TA. All patients had full clinical and laboratory assessment, cross-sectional imaging and angiography, and 16/18 satisfied the American College of Rheumatologists' criteria for TA. 18 F-FDG PET achieved a sensitivity of 92%, a specificity of 100%, and negative and positive predictive values of 85% and 100% respectively in the initial assessment of active vasculitis in TA. We conclude that 18 F-FDG PET can be used to diagnose early disease, to detect active disease (even within chronic changes) and to monitor the effectiveness of treatment. (orig.)

    Hepatic and erythrocytic glutathione peroxidase activity, together with malondialdehyde levels, were determined as indicators of peroxidation in 83 patients from whom liver biopsies had been taken for diagnostic purposes. On histological study, the patients were classified into groups as minimal changes (including normal liver), steatosis, alcoholic hepatitis, hepatic cirrhosis, light to moderately active chronic hepatitis, and severe chronic active hepatitis. The glutathione peroxidase activity in erythrocytes showed no significant changes in any liver disease group. In the hepatic study, an increased activity was observed in steatosis with respect to the minimal changes group, this increased activity induced by the toxic agent in the initial stages of the alcoholic hepatic disease declining as the hepatic damage progressed. There was a negative correlation between the levels of hepatic malondialdehyde and hepatic glutathione peroxidase in subjects with minimal changes. This suggested the existence of an oxidative equilibrium in this group. This equilibrium is broken in the liver disease groups as was manifest in a positive correlation between malondialdehyde and glutathione peroxidase activity.

    Background While formal reporting, surveillance, and response structures remain essential to protecting public health, a new generation of freely accessible, online, and real-time informatics tools for disease tracking are expanding the ability to raise earlier public awareness of emerging disease threats. The rationale for this study is to test the hypothesis that the HealthMap informatics tools can complement epidemiological data captured by traditional surveillance monitoring systems for meningitis due to Neisseria meningitides (N. meningitides) by highlighting severe transmissible disease activity and outbreaks in the United States. Methods Annual analyses of N. meningitides disease alerts captured by HealthMap were compared to epidemiological data captured by the Centers for Disease Control’s Active Bacterial Core surveillance (ABCs) for N. meningitides. Morbidity and mortality case reports were measured annually from 2010 to 2013 (HealthMap) and 2005 to 2012 (ABCs). Findings HealthMap N. meningitides monitoring captured 80-90% of alerts as diagnosed N. meningitides, 5-20% of alerts as suspected cases, and 5-10% of alerts as related news articles. HealthMap disease alert activity for emerging disease threats related to N. meningitides were in agreement with patterns identified historically using traditional surveillance systems. HealthMap’s strength lies in its ability to provide a cumulative “snapshot” of weak signals that allows for rapid dissemination of knowledge and earlier public awareness of potential outbreak status while formal testing and confirmation for specific serotypes is ongoing by public health authorities. Conclusions The underreporting of disease cases in internet-based data streaming makes inadequate any comparison to epidemiological trends illustrated by the more comprehensive ABCs network published by the Centers for Disease Control. However, the expected delays in compiling confirmatory reports by traditional surveillance systems

    This study examined how awareness of diagnostic label impacted self-reported quality of life (QOL) in persons with varying degrees of cognitive impairment. Older adults (n = 259) with normal cognition, Mild Cognitive Impairment (MCI), or mild Alzheimer's disease dementia (AD) completed tests of cognition and self-report questionnaires that assessed diagnosis awareness and multiple domains of QOL: cognitive problems, activities of daily living, physical functioning, mental wellbeing, and perceptions of one's daily life. We compared measures of QOL by cognitive performance, diagnosis awareness, and diagnostic group. Persons with MCI or AD who were aware of their diagnosis reported lower average satisfaction with daily life (QOL-AD), basic functioning (BADL Scale), and physical wellbeing (SF-12 PCS), and more difficulties in daily life (DEM-QOL) than those who were unaware (all p ≤ .007). Controlling for gender, those expecting their condition to worsen over time reported greater depression (GDS), higher stress (PSS), lower quality of daily life (QOL-AD, DEM-QOL), and more cognitive difficulties (CDS) compared to others (all p cognitive impairment. © The Author 2017.

    Full Text Available Clinical application of knowledge about risk factors and indicators associated with the loss of implants or peri-implantitis requires additional studies to demonstrate the risk of peri-implant diseases. Identification of risk factors for peri-implant mucositis and peri-implantitis will provide the clinician tools for determining the prognosis of the individual and the implant and better selection of patients for placement of implants. Progress in understanding the risk of peri-implantitis at the individual level with a careful assessment of the risk level of an implant would be useful in the planning of implant treatment.The similarity in the etiology and pathogenesis of periodontal diseases and peri-implant infections requires an assessment of periodontal status and assessing the risk of progression of periodontitis in patients with a history of periodontal disease and implants. In the literature are few and conflicting data on the relationship of periodontal status of the patient and peri-implant diseases. It is likely that the presence of periodontal pockets, showing clinical signs of an infection and activity to be associated with inflammatory peri-implant diseases.The study is focused on the discovery of a relationship between peri-implant mucositis and peri-implantitis and activity (bleeding on probing - BoP of patient’s periodontal disease. Statistically significant relationship was established between occurrence of active periodontal sites and inflammatory peri-implant diseases.

    Objectives To assess the influence of subjective word-finding difficulty on Alzheimer’s disease (AD) patients’ likelihood of engaging in social leisure activities. Design Analysis of data collected from the second cohort of the Multicenter Study of Predictors of Disease Course in Alzheimer’s disease. Setting Four study sites in the U.S. and France. Participants Individuals diagnosed with mild to moderate AD (N = 236) Measurements On separate questionnaires, patients were asked to 1) report whether had trouble finding the right word when speaking (subjective word-finding difficulty), and 2) rate their frequency and enjoyment of both social and nonsocial leisure activities. Objective language measures included object naming and verbal fluency. Measures of dependence, depression, cognitive status, age, sex, and education were also included as covariates in regression analyses. Results Over half (52%) of the sample reported word-finding difficulty, and subjective complaints were correlated with poorer verbal fluency scores. Subjective word-finding difficulty was uniquely related to social activity measures. Endorsers of word-finding difficulty reported reduced frequency and enjoyment of social leisure activities, controlling for covariates. In contrast, engagement in nonsocial activities was associated with higher age and depression scores, but was not related to word-finding complaints. These results were corroborated by the caregivers’ reports, and occurred above and beyond the effect of objective word-finding ability. Conclusion AD patients who are aware of increasing word-finding failures are less likely to participate in and enjoy socially-oriented leisure activities. This finding may have significant implications for clinical and health outcomes in AD. A failure to evaluate subjective language complaints could result in social withdrawal symptoms, thereby threatening the patient’s quality of life as well as increasing caregiver burden. Importantly

    Background. Syndecan-1 (SDC-1), a member of the family of heparan sulfate proteoglycans, plays an important role in the resolution of inflammation. This study aimed to investigate the relationship between SDC-1 and disease activity in Crohn's disease (CD). Methods. Serum samples of 54 patients with CD and 30 healthy controls were obtained. First, SDC-1 levels of the CD patients were compared to the control group. Subsequently, SDC-1 levels were analyzed in patients with CD in active and remission periods. Finally, SDC-1 efficacy in predicting disease activity was evaluated by performing correlation analysis between SDC-1 and C-reactive protein (CRP) and Crohn's disease activity index (CDAI). Results. SDC-1 level was higher in the CD group (61.9 ± 42.6 ng/mL) compared with the control group (34.1 ± 8.0 ng/mL) (p = 0.03). SDC-1 levels were higher in active CD patients (97.1 ± 40.3 ng/mL) compared with those in remission (33.7 ± 13.5 ng/mL) (p SDC-1 and CRP (r = 0.687, p SDC-1 and CDAI (r = 0.747, p SDC-1 are higher in CD compared to the normal population and can be an effective marker of disease severity.

    2003-08-01

    The spectrum of inflammatory diseases is nowadays considered to include diverse diseases of the central nervous system (CNS). Current evidence suggests that syndromes such as Alzheimer's disease (AD) have important inflammatory and immune components and may be amenable to treatment by anti-inflammatory and immunotherapeutic approaches. Compelling evidence has been reported that complement activation occurs in the brain with Alzheimer's disease, and that this contributes to the development of a local inflammatory state that is correlated with cognitive dysfunction. The complement system is a critical element of the innate immune system recognizing and killing, or targeting for destruction, otherwise pathogenic organisms. In addition to triggering the generation of a membranolytic complex, complement proteins interact with cell surface receptors to promote a local inflammatory response that contributes to the protection and healing of the host. Complement activation causes inflammation and cell damage, yet it is an essential component in trying to eliminate cell debris and potentially toxic protein aggregates. It is the balance of these seemingly competing events--the "Yin" and the "Yang"--that influences the ultimate state of neuronal function. Knowledge of the unique molecular interactions that occur in the development of Alzheimer's disease, the functional consequences of those interactions, and the proportional contribution of each element to this disorder, should facilitate the design of effective therapeutic strategies for this disease.

    Full Text Available Background: The principle features of Attention deficit hyperactivity disorder (ADHD are hyperactivity, inattention and impulsivity. There is little evidence that confirms that Attention deficit hyperactivity disorder (ADHD is arising purely from child rearing methods or social factors.76 % of children with ADHD has a family history, and the similar cases can be seen in the family. The symptoms of more than 50 % of ADHD children will continue in adulthood which requires treatment. Most of the causes appear for ADHD are categorizing the condition in a group of neurobiological and genetic disorders. This does not mean to say that the influence of environmental factors on the severity of disorder, impairment and suffering the child may experience is nil, but those factors do not give rise to the condition by themselves. The chances of getting associated problems like Oppositional Defiant Disorder (ODD in children with ADHD is one-third to one-half and ODD is more common in boys with ADHD. These children are often non compliant, stubborn, defiant, have outbursts of temper, or become belligerent. Case description: This is a case report of a child who diagnosed as attention deficit hyper active disordered and Oppositional Defiant Disordered (ODD child, with finger contractures of right hand, which treated with medications, behavioral therapy, physiotherapy, relaxation techniques and music therapy as the means of rehabilitation. Outcome measures: The evaluation measures used are Nine-hole peg test, behavioral rating scale and a seven items temperament evaluation scale. Discussion: A holistic rehabilitation therapy increased attention, listening to suggestions, short stories and sleeping in time. Oppositional behaviors were also reduced both at home and school. Her relationships with parent, teachers and school mates were improved. Listening skills, attention, daily activities such as wake up, brushing, bathing, going to school in time were also

    Full Text Available Thiamine metabolites and activities of thiamine-dependent enzymes are impaired in Alzheimer's disease (AD.To clarify the mechanism for the reduction of thiamine diphosphate (TDP, an active form of thiamine and critical coenzyme of glucose metabolism, in AD.Forty-five AD patients clinically diagnosed and 38 age- and gender-matched control subjects without dementia were voluntarily recruited. The contents of blood TDP, thiamine monophosphate (TMP, and thiamine, as well as the activities of thiamine diphosphatase (TDPase, thiamine monophosphatase (TMPase, and thiamine pyrophosphokinase (TPK, were assayed by high performance liquid chromatography.Blood TDP contents of AD patients were significantly lower than those in control subjects (79.03 ± 23.24 vs. 127.60 ± 22.65 nmol/L, P 0.05. Blood TDP levels correlated negatively with TDPase activities (r = -0.2576, P = 0.0187 and positively with TPK activities (r = 0.2426, P = 0.0271 in all participants.Enhanced TDPase and TMPase activities may contribute to the reduction of TDP level in AD patients. The results imply that an imbalance of phosphorylation-dephosphorylation related to thiamine and glucose metabolism may be a potential target for AD prevention and therapy.

    Full Text Available Nonalcoholic fatty liver disease (NAFLD is the most common liver disease worldwide and it is associated with other medical conditions such as diabetes mellitus, metabolic syndrome, and obesity. The mechanisms of the underlying disease development and progression are not completely established and there is no consensus concerning the pharmacological treatment. In the gold standard treatment for NAFLD weight loss, dietary therapy, and physical activity are included. However, little scientific evidence is available on diet and/or physical activity and NAFLD specifically. Many dietary approaches such as Mediterranean and DASH diet are used for treatment of other cardiometabolic risk factors such as insulin resistance and type-2 diabetes mellitus (T2DM, but on the basis of its components their role in NAFLD has been discussed. In this review, the implications of current dietary and exercise approaches, including Brazilian and other guidelines, are discussed, with a focus on determining the optimal nonpharmacological treatment to prescribe for NAFLD.

    Inflammatory bowel disease, including ulcerative colitis and Crohn's disease, comprising a broad spectrum of diseases those have in common chronic inflammation of the gastrointestinal tract, histological alterations and an increased activity levels of certain enzymes, such as, metalloproteinases. Evaluate a possible correlation of disease activity index with the severity of colonic mucosal damage and increased activity of metalloproteinases in a model of ulcerative colitis induced by dextran sulfate sodium. Colitis was induced by oral administration of 5% dextran sulfate sodium for seven days in this group (n=10), whereas control group (n=16) received water. Effects were analyzed daily by disease activity index. In the seventh day, animals were euthanized and hematological measurements, histological changes (hematoxylin and eosin and Alcian Blue staining), myeloperoxidase and metalloproteinase activities (MMP-2 and MMP-9) were determined. Dextran sulfate sodium group showed elevated disease activity index and reduced hematological parameters. Induction of colitis caused tissue injury with loss of mucin and increased myeloperoxidase (Pcorrelation with the degree of histopathological changes after induction of colitis, and this result may be related mainly to the increased activity of MMP-9 and mieloperoxidase.

    Objective ambulatory activity during daily living has not been characterized for people with Parkinson disease prior to initiation of dopaminergic medication. Our goal was to characterize ambulatory activity based on average daily step count and examine determinants of step count in nonexercising people with de novo Parkinson disease. We analyzed baseline data from a randomized controlled trial, which excluded people performing regular endurance exercise. Of 128 eligible participants (mean ± SD = 64.3 ± 8.6 years), 113 had complete accelerometer data, which were used to determine daily step count. Multiple linear regression was used to identify factors associated with average daily step count over 10 days. Candidate explanatory variable categories were (1) demographics/anthropometrics, (2) Parkinson disease characteristics, (3) motor symptom severity, (4) nonmotor and behavioral characteristics, (5) comorbidities, and (6) cardiorespiratory fitness. Average daily step count was 5362 ± 2890 steps per day. Five factors explained 24% of daily step count variability, with higher step count associated with higher cardiorespiratory fitness (10%), no fear/worry of falling (5%), lower motor severity examination score (4%), more recent time since Parkinson disease diagnosis (3%), and the presence of a cardiovascular condition (2%). Daily step count in nonexercising people recruited for this intervention trial with de novo Parkinson disease approached sedentary lifestyle levels. Further study is warranted for elucidating factors explaining ambulatory activity, particularly cardiorespiratory fitness, and fear/worry of falling. Clinicians should consider the costs and benefits of exercise and activity behavior interventions immediately after diagnosis of Parkinson disease to attenuate the health consequences of low daily step count.Video Abstract available for more insights from the authors (see Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A170).

    Acute pancreatitis has a highly variable course. Currently there is no widely accepted method to measure disease activity in patients hospitalized for acute pancreatitis. We aimed to develop a clinical activity index that incorporates routine clinical parameters to assist in the measurement, study, and management of acute pancreatitis. We used the UCLA/RAND appropriateness method to identify items for inclusion in the disease activity instrument. We conducted a systematic literature review followed by two sets of iterative modified Delphi meetings including a panel of international experts between November 2014 and November 2015. The final instrument was then applied to patient data obtained from five separate study cohorts across Southern California to assess profiles of disease activity. From a list of 35 items comprising 6 domains, we identified 5 parameters for inclusion in the final weighted clinical activity scoring system: organ failure, systemic inflammatory response syndrome, abdominal pain, requirement for opiates and ability to tolerate oral intake. We applied the weighted scoring system across the 5 study cohorts comprising 3,123 patients. We identified several distinct patterns of disease activity: (i) overall there was an elevated score at baseline relative to discharge across all study cohorts, (ii) there were distinct patterns of disease activity related to duration of illness as well as (iii) early and persistent elevation of disease activity among patients with severe acute pancreatitis defined as persistent organ failure. We present the development and initial validation of a clinical activity score for real-time assessment of disease activity in patients with acute pancreatitis.

    Disease activity can be determined using clinical, endoscopic or histologic criteria in patients with ulcerative colitis (UC). Persistent disease activity is associated with poor outcomes. Histologic disease activity has been shown to be associated with relapse, colectomy and colorectal cancer. The ability to objectively evaluate microscopic disease activity using histology is important for both clinical practice and clinical trials. However, the operating properties of the currently available histologic indices remain unclear. A systematic review was undertaken to identify and evaluate the development and operating characteristics of histologic disease activity indices used to assess disease activity in people with ulcerative colitis. We searched MEDLINE, EMBASE, PubMed, CENTRAL and the Cochrane IBD Review Group Specialized Trials Register from inception to 2 December 2016 for applicable studies. There were no language or document type restrictions. Any study design (e.g. randomized controlled trials, cohort studies, case series) that evaluated a histologic index in patients with UC were considered for inclusion. Eligible patients were adults (> 18 years), diagnosed with UC using conventional clinical, radiographic, endoscopic and histologic criteria. Two authors (MHM and CEP) independently reviewed the titles and abstracts of the studies identified from the literature search. A standardized form was used to assess eligibility of trials for inclusion and for data extraction.Two authors (MHM and CEP) independently extracted and recorded data, which included the number of patients enrolled, number of patients per treatment arm, patient characteristics including age and gender distribution, and the name of the histologic index. Outcomes (i.e. intra-rater reliability, inter-rater reliability, internal consistency, content validity, criterion validity, construct validity, responsiveness, and feasibility) were recorded for each trial. In total, 126 reports describing 30

    Full Text Available It was shown recently that angiotensin-converting enzyme activity is limited by endogenous inhibition in vivo, highlighting the importance of angiotensin II (ACE2 elimination. The potential contribution of the ACE2 to cardiovascular disease progression was addressed. Serum ACE2 activities were measured in different clinical states (healthy, n=45; hypertensive, n=239; heart failure (HF with reduced ejection fraction (HFrEF n=141 and HF with preserved ejection fraction (HFpEF n=47. ACE2 activity was significantly higher in hypertensive patients (24.8±0.8 U/ml than that in healthy volunteers (16.2±0.8 U/ml, p=0.01. ACE2 activity further increased in HFrEF patients (43.9±2.1 U/ml, p=0.001 but not in HFpEF patients (24.6±1.9 U/ml when compared with hypertensive patients. Serum ACE2 activity negatively correlated with left ventricular systolic function in HFrEF, but not in hypertensive, HFpEF or healthy populations. Serum ACE2 activity had a fair diagnostic value to differentiate HFpEF from HFrEF patients in this study. Serum ACE2 activity correlates with cardiovascular disease development: it increases when hypertension develops and further increases when the cardiovascular disease further progresses to systolic dysfunction, suggesting that ACE2 metabolism plays a role in these processes. In contrast, serum ACE2 activity does not change when hypertension progresses to HFpEF, suggesting a different pathomechanism for HFpEF, and proposing a biomarker-based identification of these HF forms.

    Sarcoidosis is a systemic chronic inflammatory disease of unknown aetiology, characterised by granulomatous lesions with heterogeneous clinical manifestations affecting multiple organs and tissues. Although the respiratory system is most commonly affected, the disease may also present with bone lesions. We report the case of a 31-year old woman who presented with low back pain and no history of cancer and who was found to have suspicious lesions involving the entire spine on magnetic resonance imaging (MRI). The patient underwent {sup 18}F-fluorodeoxyglucose (FDG) PET/CT to search for a primary tumour and for staging purposes. {sup 18}F-FDG PET/CT revealed a pattern of hypermetabolic activity in widespread skeletal lesions and in a single left cervical lymph node. The primary tumour was not found, thus suggesting a haematologic disorder. Subsequent biopsies of a cervical lymph node and of bone tissue from L4 revealed active sarcoidosis with no evidence of cancer. This underlines the importance of considering all alternatives when hypermetabolic lesions are found on {sup 18}F-FDG PET/CT. Furthermore, {sup 18}F-FDG PET can be very useful to indicate accessible sites for guiding fine-needle aspiration cytology (FNAC)

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

    Background: ln the current context of increasing numbers of children living with a chronic disease and increasing numbers of people supervising extracurricular activities, difficulties appear to persist despite the Personalised Core Project (PCP). This study explores the accessibility and usefulness of the information provided by the Personalised Care Project and the value of complementary support. Methods: Based on the key messages identified by experts in the four most common chronic diseases, a questionnaire was deve/oped and sent to people supervising extracurricular activities in three districts of the Saône-et-Loire department. Descriptive statistical analysis was performed. Results: 55 people participated in the study. 30 (54.5%) had already supervised children with a chronic disease, 21 (70%) of them had been able to read the PCP and 17 (57%) had participated in an information meeting. 23 out of 28 (82%) considered thot the information contained in the PCP was helpful and 21 (81%) expressed their needs for further information. 98% of respondents thought thot additional support would be useful. Their main needs corresponded to 3 main self-core ski/Js: to recognize, analyse and measure; to deal with and decide; to resolve prevention problems. Conclusion: This study confirms the value of the PCP, but also the Jack of preparation of people supervising extracurricu/ar activ ities. lt highlights the need for training to allow these people to ensure the safety of chi /dren living with chronic diseases.

    Tuberculosis (TB) is a serious opportunistic infection in renal transplant recipients associated with high mortality. Screening and treatment of latent Mycobacterium tuberculosis infection (LTBI) offers an opportunity to prevent subsequent active disease. We retrospectively reviewed the records of all adult patients who underwent renal transplantation at our centre from 2005 to 2014 to assess current screening practices, the risks for and burden of active TB. A total of 660 individuals underwent renal transplantation during this period, totalling 3647 person years of follow up. Three patients were diagnosed with active TB after renal transplant, resulting in an incidence of 82 per 100,000 person-years. Of 656 transplant recipients, 102 (15.5%) were born in high TB incidence countries and 89 (13.5%) had an interferon gamma release assay (IGRA) at any point. Individuals born in high TB risk countries had a much higher incidence of active TB (530 per 100,000 person-years). Ten individuals had positive IGRA tests, of whom two were treated for active TB, two received chemoprophylaxis and six were not treated. In the absence of formal guidelines, IGRA-based screening for LTBI was infrequently performed. Our data suggests that screening and treatment of renal transplant recipients born in high incidence countries is an important preventive measure. This article is protected by copyright.

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

    To determine whether patients with neuropsychiatric (NP) events attributed to systemic lupus erythematosus (SLE) have more global disease activity than patients with NP events not attributed to SLE. Patients were recruited from an academic lupus clinic. Global disease activity was measured with the SLE Disease Activity Index 2000 (SLEDAI-2K) and organ damage with the Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology (ACR) damage index (SDI). NP disease was defined using the ACR case definitions and decision rules for attribution of NP events to SLE and non-SLE causes. There were 68 patients (age (mean ± SD) 40.8 ± 15.2 years, 85% female, 94% Caucasians) with 126 NP events. SLEDAI-2K scores in patients with NP events attributed to SLE were higher than in patients with NP events attributed to non-SLE causes even when NP variables were removed from the SLEDAI-2K (mean ± SD: SLE NP = 7.36 ± 5.42 vs non-SLE NP = 5.53 ± 4.57, P = 0.042). Patients with CNS and diffuse NP events, rather that PNS and focal events, accounted for the group differences in SLEDAI-2K scores. There were no significant differences in total SDI scores comparing NP events due to SLE vs. non-SLE causes (mean ± SD: 2.1 ± 1.8 vs. 1.7 ± 1.7; p = 0.28) even when NP variables were omitted. Increased global SLE disease activity is associated with concurrent NP events attributed to SLE, particularly for diffuse NP and CNS NP events. The findings have diagnostic and therapeutic implications for SLE patients with NP events and inform pathogenetic mechanisms underlying NPSLE.

  8. The green turtle Chelonia mydas as a marine and coastal environmental sentinels: anthropogenic activities and diseases

    Full Text Available The green turtle Chelonia mydas is a widely distributed, slowly maturing species with a complex life cycle, using both oceanic and coastal environments. The species is exposed to different threats and is considered an environmental sentinel that indicates variation among, and the severity of hazards to marine ecosystems. This study aimed to describe both anthropogenic impacts, and infectious and parasitic diseases in C. mydas - including cases along the Brazilian coast - and implications for conservation. Bycatch is reported as the main threat to the conservation of this species, followed by debris ingestion, collisions with boats, dredging, and chronic environmental contamination. All of these impacts may directly or indirectly cause death, by facilitating contact with pathological agents and by increasing vulnerability to secondary diseases. The pathological agents associated with lesions include viruses, bacteria, fungi, protozoa, and helminths. Fibropapillomatosis is an example of a chronic disease characterized by cutaneous and visceral tumors that affects mostly juvenile C. mydas worldwide and is associated with the Chelonid herpesvirus 5. The bacterias Vibrio alginolyticus, Aeromonas hydrophila, and Pseudomonas fluorescens are found in the aquatic environment and among C. mydas lesions in various organs. Trematode adults and eggs of the family Spirorchiidae are also frequent in systemic cardiovascular diseases of C. mydas. The direct impacts of anthropogenic activities and diseases are synergistic and may affect the specie’s health and conservation. Therefore, the monitoring and systematic diagnosing of diseases and causes of death - including necropsy, histopathology, and molecular exams - are necessary to assess a population’s health, to support appropriate decisions of coastal management and to target future research topics that optimize C. mydas conservation.

    Full Text Available Introduction: The aim was to assess the usefulness of TGF-β1 and elastase in the evaluation of activity of ulcerative colitis (UC and Crohn’s disease (CD.Material and Methods: 32 patients diagnosed with UC, 31 with CD and 30 healthy volunteers were enrolled in this study. Diagnosis of the disease was confirmed by videocolonoscopy and histopathological evaluation of intestinal biopsies. Disease activity was assessed by use of the Mayo Scoring System for Assessment of Ulcerative Colitis Activity in UC patients and by CDAI in CD patients. hsCRP was determined by the immunonephelometric method, TGF-β1 and elastase plasma concentration by ELISA. The results of the study were analyzed using Statistica and R statistical language.Results: In UC a positive correlation between disease activity and platelet level, hsCRP and TGF-β1 concentration was noted. Elastase concentration in UC patients was significantly higher than in CD, but there was no correlation with the activity of the disease. In CD patients we observed a positive correlation between disease activity and leukocytes, platelet levels and elastase concentration, and a very low correlation with hsCRP and TGF-β1.Discussion: Determination of TGF-β1 can be used for evaluation of inflammatory activity in UC and it is connected with elevated concentrations of CRP and platelets. To a lower extent TGF-β1 can also be used for evaluation of inflammatory activity in CD. Examination of elastase concentration may be useful in the assessment of CD activity. Plasma elastase concentration may be helpful in UC and CD differentiation. The preliminary results of this investigation seem promising; nevertheless, more studies are necessary.

    We investigated the association between autoantibodies against non-myeloperoxidase (MPO) neutrophil granule antigens and activity of Behçet's disease (BD). We consecutively enrolled 51 BD patients. We assessed clinical data and BD activity using patients' index scores from the Behçet's Disease Current Activity Form and we performed tests for antibodies against proteinase 3 (PR3), MPO, bactericidal permeability increasing protein (BPI), cathepsin G, elastase, lactoferrin and lysozyme. The median patient index score was 2.0, and 56.9% of patients had active BD. In multivariate analysis of variables with significant correlations, only anti-lysozyme showed a significant correlation with BD activity (P = 0.002). In multivariate logistic regression analyses of variables, when patients were classified into groups according to the optimal cutoff levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and anti-lysozyme (ESR > 42.5 mm/h, CRP > 1.35 mg/L and anti-lysozyme > 2.95 IU/mL), the variable with independent predictive value was anti-lysozyme (odds ratio 8.384, P = 0.015). Anti-lysozyme was significantly correlated with disease activity score and it was the only independent value to predict active disease in patients with BD. Furthermore, patients having anti-lysozyme levels ≥ 2.95 IU/mL had a significantly higher risk of having active BD than those who did not. © 2016 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

    Graves' disease is the most common cause of hyperthyroidism in the United States. Graves' disease occurs more often in women with a female:male ratio of 5:1 and a population prevalence of 1% to 2%. A genetic determinant to the susceptibility to Graves' disease is suspected because of familial clustering of the disease, a high sibling recurrence risk, the familial occurrence of thyroid autoantibodies, and the 30% concordance in disease status between identical twins. Graves' disease is an autoimmune thyroid disorder characterized by the infiltration of immune effector cells and thyroid antigen-specific T cells into the thyroid and thyroid-stimulating hormone receptor expressing tissues, with the production of autoantibodies to well-defined thyroidal antigens, such as thyroid peroxidase, thyroglobulin, and the thyroid-stimulating hormone receptor. The thyroid-stimulating hormone receptor is central to the regulation of thyroid growth and function. Stimulatory autoantibodies in Graves' disease activate the thyroid-stimulating hormone receptor leading to thyroid hyperplasia and unregulated thyroid hormone production and secretion. Below-normal levels of baseline serum thyroid-stimulating hormone receptor, normal to elevated serum levels of T4, elevated serum levels of T3 and thyroid-stimulating hormone receptor autoantibodies, and a diffusely enlarged, heterogeneous, hypervascular (increased Doppler flow) thyroid gland confirm diagnosis of Graves' disease (available at: http://supplements.amjmed.com/2010/hyperthyroid/faculty.php).

    Nonalcoholic fatty liver disease (NAFLD) is associated with obesity and insulin resistance and has been linked with increased cardiovascular risk. Although physical activity (PA) and lifestyle modification are often recommended in patients at cardiovascular risk, the benefit across the cardiometabolic risk spectrum is unclear. We aimed to evaluate the relation of PA and NAFLD independent of metabolic syndrome (MS) or obesity. We evaluated 5,743 healthy Brazilian subjects (43 ± 10 years, 79% men) without clinical coronary heart disease from December 2008 to December 2010. NAFLD was diagnosed using ultrasounds, and self-reported PA was assessed using the International Physical Activity Questionnaire scale. In a multivariate logistic regression adjusted for cardiometabolic risk factors, we evaluated for an independent association of NAFLD and PA. In the total study population, NAFLD prevalence was 36% (n = 2,075), obesity 23% (1,300), and MS 20% (1,152). NAFLD was more prevalent in subjects with MS (74%) than those without (26%) and in those obese (73%) than in those nonobese (25%). Overall, 1,305 (23%) subjects reported low activity, 1,990 (35%) moderate activity, and 2,448 (42%) high activity. NAFLD prevalence was lower at higher levels of reported PA (low 45%, moderate 38%, and high 30%, p activity had lower odds of having NAFLD. The favorable association was independent of obesity or MS. In conclusion, PA presents a dose-response association with NAFLD independent of the MS or obesity. Our results are compatible with the idea that benefits of PA are relevant to everyone regardless of cardiometabolic risk. Copyright © 2015 Elsevier Inc. All rights reserved.

    2017-08-01

    The aim of this study was to determine the paraoxonase (PON) and arylesterase (ARE) enzyme activity levels in Behcet's disease (BD) and to investigate whether they are associated with the disease activity. Twenty-six patients (study group) with active BD and 28 healthy controls (control group) were included in this study. While the patients who had at least one of the symptoms related to genital ulcer, skin lesions, active uveitis, arthritis, thrombophlebitis, or central nervous system involvement in addition to oral ulcers were considered as the active group, the patients who did not show clinical symptoms in the last one month due to the medical treatment were considered as the inactive group in the clinical evaluation of patients with BD. The PON and ARE levels were found to be significantly lower in the study group than the control group (p  0.05). The activities of the antioxidant PON and ARE enzymes are reduced in BD. Therefore, it may be useful to add antioxidant therapy to the conventional treatment of the disease.

    We report the case of a 53 year old man with a chronic periaortitis (CP) in whom Fluorine 18 Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) has been useful in assessing the disease extent at diagnosis, in evaluating the treatment response, in diagnosing the relapse, and in monitoring the disease activity during follow up. This case highlights the usefulness of FDG PET/CT at different times in patients with CP. CP is a rare inflammatory disorder that affects the abdominal aorta and the retroperitoneum. Imaging procedures are essential to diagnose and monitor the disease course. Ultrasonography may be used as first line screening test, and is particularly useful to monitor patients with hydronephrosis and aortic aneurysms. However, CT or magnetic resonance imaging (MRI) of the abdomen are currently considered the investigations of choice to diagnose CP. In active CP, the periaortic mass usually enhances on CT and MRI. Both these methods can be used to monitor the disease course of CP and to evaluate response to treatment. A note of caution: signs of vasculitis seen on MRI and CT may persist for some time, despite achievement of clinical remission. A further limitation of abdominal CT and MRI is that neither technique can detect vasculitis in vessels other than the abdominal aorta, which has been described in 43% of patients with CP. FDG PET/CT has been proposed as useful tool in inflammatory diseases, such as aortitis, because metabolic changes assessed by FDG PET/CT usually precede morphological changes assessed by conventional imaging methods. Our case highlights the usefulness of FDG PET/CT at different times in patients with CP. This method may be useful in assessing disease activity and extent at diagnosis, in evaluating the treatment response, in diagnosing the relapse, and in monitoring the disease during follow up.
