    Implant therapy has become a widely recognized treatment alternative for replacing missing teeth. Several long term follow-up studies have shown that the survival rate is high. However, complications may appear and risk indcators associated with early and late failures have been identified. The purpose of the present retrospective clinical study was to describe some clinical features of patients with clinical signs of peri-implantitis and to identify risk indicators of peri-implantitis in a population at a specialist clinic of Periodontology. In total,the material consisted of 377 implants in 111 patients with the diagnosis peri-implantitis. The mean age at the examination was found to be 56.3 years (range 22-83) for females and 64.1 years (range 27-85) for males. The mean number of remaining teeth was found to be 10.5 (S.D. 8.89) and the mean number of implants was 5.85 (S.D. 3.42). For a majority of the subjects, more than 50% of the remaining teeth had a marginal bone loss of more than 1/3 of the root length. Forty-sex percent of the patients visited regularly dental hygienists for supportive treatment. The percentage of implants with peri-implantitis was significantly increased for smokers compared to non-smokers (p = 0.04). In the group of non-smokers, 64% of the implants had the diagnosis peri-implantitis, while the corresponding relative frequency for smokers was 78%. A majority of the individuals had a Plaque index and Bleeding on probing index >50%. The median of the follow-up time after implant placement was 7.4 years and the observation period was not significantly correlated to the degree of bone loss around the implants. Among the subjects with a mean bone loss >6 mm at implants with peri-implantitis, more than 70% had a mean marginal bone loss > 1/3 of the root length of the remaining teeth. A positive and significant correlation was found between the degree of marginal bone loss in remaining teeth and the degree of bone loss around implants with peri

    Venous thrombosis is common in older age, with an incidence of 0·5-1% per year in those aged >70 years. Stasis of blood flow is an important contributor to the development of thrombosis and may be due to venous insufficiency in the legs. The risk of thrombosis associated with clinical features of venous insufficiency, i.e., varicose veins, leg ulcers and leg oedema, obtained with a standardized interview was assessed in the Age and Thrombosis Acquired and Genetic risk factors in the Elderly (AT-AGE) study. The AT-AGE study is a case-control study in individuals aged 70 years and older (401 cases with a first-time venous thrombosis and 431 control subjects). We calculated odds ratios (ORs) and corresponding 95% confidence intervals (CI) adjusted for age, sex and study centre. Varicose veins and leg ulcer were associated with a 1·6-fold (95% CI 1·2-2·3) and 3·3-fold increased risk of thrombosis (95% CI 1·6-6·7), respectively, while the risk was increased 3·0-fold (95% CI 2·1-4·5) in the presence of leg oedema. The risk of thrombosis was highest when all three risk factors occurred simultaneously (OR: 10·5; 95% CI 1·3-86·1). In conclusion, clinical features of venous insufficiency, i.e., varicose veins, leg ulcers and leg oedema, are risk factors for venous thrombosis in older people.

    AIM: There is still no accepted conclusion regarding the clinical features and related risk factors of patients with fatty liver. The large-scale clinical studies have not carried out yet in Guangzhou area. The aim of the present study was to investigate the clinical features and related risk factors of patients with fatty liver in Guangzhou area. METHODS: A total of 413 cases with fatty liver were enrolled in the study from January 1998 to May 2002. Retrospective case-control study was used to evaluate the clinical featuresand related risk factors of fatty liver with logistic regression.RESULTS: Obesity (OR: 21.204), alcohol abuse (OR: 18.601),type 2 diabetes mellitus (OR: 4.461), serum triglyceride (TG)(OR: 3.916), serum low-density lipoprotein cholesterol (LDL-C)(OR: 1.840) and fasting plasma glucose (FPG) (OR: 1.535)were positively correlated to the formation of the fatty liver. The levels of serum alanine aminotransferase (ALT) and gammaglutamyltransferase (GGT) increased mildly in the patients withfatty liver and were often less than 2-fold of the normal limit.The higher abnormalities of aspartate aminotransferase (AST)levels (42.9%) with Asr/ALT more than 2(17.9%) were found in patients with alcoholic fatty liver (AFL) than those with nonalcoholic fatty liver (NAFL) (16.9% and 5.0% respectively). The elevation of serum TG, cholesterol (CHOL), LDL-C was more common in patients with NAFL than with AFL.CONCLUSION: Obesity, alcohol abuse, type 2 diabetes mellitus and hyperlipidemia may be independent risk factors of fatty liver. The mildly abnormal hepatic functions can be found in patients with fatty liver. More obvious damages of liver function with AST/ALT usually more than 2 were noted in patients with AFL.

    Full Text Available OBJECTIVES: Clinical features and risk factors for atazanavir (ATV-associated urolithiasis have not been fully investigated. METHODS: We reviewed all cases of ATV-containing urolithiasis identified by infrared spectrophotometry among HIV-infected patients over a 5-year period to describe their clinical features and outcome. A case-control study was performed to identify risk factors associated with ATV-associated urolithiasis using univariate and multivariate logistic regression analyses. RESULTS: 30 cases of ATV-associated urolithiasis were analyzed. Patients were mostly men (87%, median age: 45.5 years, median CD4 cell count: 443 cells/µL and 97% had plasma HIV RNA level <50 cp/mL. Median time between the initiation of ATV-containing regimen and the diagnosis of urolithiasis was 3.1 years. Patients presented with flank pain in 90% and macroscopic hematuria in 82.6%, 34% had renal dysfunction and 44.8% needed ureteroscopic treatment. In univariate analysis, chronic hepatitis C, a history of urolithiasis, prior use of indinavir, ATV duration, undetectable plasma HIV RNA, use of ritonavir as a booster and serum free bilirubin level were associated with ATV-urolithiasis. Multivariate models retained serum free bilirubin level (OR: 2.31, p<0.02 and either ATV duration (OR:  = 1.42, p = <0.03 or a history of urolithiasis (OR = 4.79, p<0.02 when adjusting on serum free bilirubin level as risk factors associated with urolithiasis. CONCLUSIONS: ATV-containing urolithiasis are associated with frank clinical symptoms and may require surgical intervention. A high serum bilirubin level, a long exposure to ATV and a history of urolithiasis are risk factors for this rare adverse event.

    Cyclosporin A is associated with an acute encephalopathy including seizures and alterations in mental status, herein referred to as cyclosporin A acute encephalopathy and seizure syndrome. The clinical history, electroencephalogram (EEG), and neuroimaging findings in 19 children with cyclosporin A acute encephalopathy and seizure syndrome over a 10-year period were reviewed in order to delineate clinical characteristics, imaging features, and to determine the risk of seizure recurrence in this population. All 19 had motor seizures associated with other features of cortical and subcortical dysfunction. The acute mean cyclosporin A level was 342 microg/L, but was within the "therapeutic" range in five cases. Brain imaging by computed tomography (CT) or magnetic resonance imaging (MRI) in the acute or subacute phase revealed lesions characteristic of cyclosporin A toxicity in 14 cases. Acute EEG abnormalities were present in all and included epileptiform discharges or focal slowing. Patients were followed for a median of 49 months (1-9 years). Follow-up imaging (n = 10) showed lesion resolution or improvement in the majority while EEG (n = 10) had normalized in only three. Seizures recurred in six patients and only in those with persistent EEG or imaging abnormalities. No patient had a second episode of cyclosporin A associated neurotoxicity or seizure. It appears that a significant risk of seizure recurrence exists following cyclosporin A acute encephalopathy and seizure syndrome and primarily in those children with persistent EEG or imaging abnormalities.

    Infections caused by carbapenem-producing Enterobacteriaceae (CPE) can present as several infectious syndromes, but they primarily present as respiratory, urinary and blood stream infections (primary or catheter-related) that are usually found as nosocomial or healthcare-associated infections. The risk of CPE infection is influenced by individual factors, such as the length of the hospital stay and their exposure to invasive procedures and/or to antimicrobials. Of note, exposure to several antimicrobials, not only carbapenems, has been linked to CPE colonization; the duration of antibiotic exposure is one of the primary drivers of CPE acquisition. Individual risk factors must be considered jointly with the local epidemiology of these microorganisms in healthcare institutions. Overall, these infections have a high associated mortality. Mortality is influenced by host factors (e.g., age, comorbidity and immune deficiency), infection-related variables (e.g., type and severity of the infection) and treatment-related factors such as the delay in the initiation of appropriate antimicrobial therapy and the use or monotherapy or combined antimicrobial therapy. Gaining knowledge concerning the epidemiology, clinical features and prognostic features of CPE infection could be useful for improving infection prevention and for the management of patients with infections caused by these microorganisms.

    Strongyloidiasis is a parasitic infection caused by Strongyloides stercoralis. The infection is usually mild or asymptomatic in normal immunocompetent individuals, but could be very severe or even fatal due to hyper infection in individuals who are immunosuppressed. This study aimed at determining the prevalence, risk factors and features of strongyloidiasis among diarrhea patients in Ibadan. This is a descriptive cross-sectional study of diarrhea patients from a teaching hospital, three major government hospitals and one mission hospital in Ibadan. Self administered questionnaire, clinical assessment and laboratory investigations were used to confirm health status and presence of S. stercoralis. Diagnosis was made by microscopic examination of stool in saline preparation and formol-ether concentration. One thousand and ninety patients, (562 (51.6%) males and 528 (48.4%) females) consisting 380 (34.9%) children and 710 (65.1%) adults who had diarrhea were studied. The prevalence rate for the parasite among diarrhea patients was 3.0%. While the risk factor for infection remains contact with contaminated soil, malnutrition, steroid therapy, HIV/AIDS, lymphomas, tuberculosis, and chronic renal failure. Others are maleness, institutionalism and alcoholism. Predominant clinical presentations are abdominal pain, chronic diarrhea, and bloating and weight loss, Strongyloides stercoralis should be considered in diarrhea patients who are either malnourished or immunosuppressed.

    Purpose: To determine the clinical features and risk factors of presumed ocular toxoplasmosis (POT) in patients affected with the condition at Irrua, Nigeria. Methods: The study included 69 patients with POT, and 69 age and sex matched subjects who served as the control group. Data was obtained using interviewer administered questionnaires. Examination included measurement of visual acuity (VA), intraocular pressure (IOP), slit lamp examination, gonioscopy and dilated fundus examination. Results: Mean age of cases and control subjects was 57.16 ± 18.69 and 56.09 ± 16.01 years respectively. The peak age group in patients with POT was 60 years and above. The most common presenting complaint was blurred vision occurring in 100% of cases. Drinking unfiltered water in 58 (84.1%) patients was the most common risk factor. Other risk factors included post cataract surgery status in 32 (46.4%) subjects, ingestion of poorly cooked meat in 30 (43.5%) cases and exposure to cats in 9 (13.0%) patients. All risk factors were more common in POT patients (P < 0.05). Out of 69 patients, 62 (89.9%) had unilateral while 7 (10.1%) had bilateral involvement. Out of 76 eyes with uveitis, 53 (69.7%) were blind. Active disease was significantly more common with increasing age (P < 0.05). Conclusion: Patients with POT were rather old and some risk factors were modifiable, therefore health education for preventing the transmission of toxoplasmosis and provision of sanitary water may help reduce the incidence of ocular toxoplasmosis.

    Introduction: Despite increasing the use of magnetic resonance imaging (MRI), cerebral venous sinus thrombosis (CVST) has remained an under-diagnosed condition. In this study, characteristics and frequency of various risk factors of CVST patients in a tertiary referral hospital were closely assessed. Methods: Patients with an unequivocal diagnosis of CVST confirmed by MRI and magnetic resonance venography during 6 years of the study were included. All data from the onset of symptoms regarding clinical signs and symptoms, hospital admission, seasonal distribution, medical and drug history, thrombophilic profile, D-dimer, neuroimaging, cerebrospinal fluid findings, mortality, and outcome were collected and closely analyzed. Result: A total of 53 patients with female to male ratio of 3.07 and mean age of 33.7 years were included in the study. Headache and papilledema were the most frequent clinical features (44 and 36 patients, respectively). An underlying disease (diagnosed previously or after admission) was the most common identified risk factor for CVST in both females and males (21 patients). A total of 15 women used the oral contraceptive pill (OCP) where 12 of them had simultaneously other predisposing factors. Overall, 19 patients (36%) had more than one contributing factor. D-dimer had a sensitivity of 71.4% in CVST patients. The mortality of patients in this study was 3.7% (n = 2). Focal neurologic deficit and multicranial nerve palsy were associated with poor outcome which defined as death, recurrence, and massive intracranial hemorrhage due to anticoagulation (P = 0.050 and 0.004, respectively). Conclusion: Unlike most of the CVST studies in which OCP was the main factor; in this study, an underlying disease was the most identified cause. Considering the high probability of multiple risk factors in CVST that was shown by this study, appropriate work up should be noted to uncover them. PMID:27695236

    Full Text Available Background: Deep venous thrombosis (DVT contributes significantly to the morbidity and mortality of neurosurgical patients; however, no data regarding lower extremity DVT in postoperative Chinese neurosurgical patients have been reported. Materials and Methods: From January 2012 to December 2013, 196 patients without preoperative DVT who underwent neurosurgical operations were evaluated by color Doppler ultrasonography and D-dimer level measurements on the 3rd, 7th, and 14th days after surgery. Follow-up clinical data were recorded to determine the incidence of lower extremity DVT in postoperative neurosurgical patients and to analyze related clinical features. First, a single factor analysis, Chi-square test, was used to select statistically significant factors. Then, a multivariate analysis, binary logistic regression analysis, was used to determine risk factors for lower extremity DVT in postoperative neurosurgical patients. Results: Lower extremity DVT occurred in 61 patients, and the incidence of DVT was 31.1% in the enrolled Chinese neurosurgical patients. The common symptoms of DVT were limb swelling and lower extremity pain as well as increased soft tissue tension. The common sites of venous involvement were the calf muscle and peroneal and posterior tibial veins. The single factor analysis showed statistically significant differences in DVT risk factors, including age, hypertension, smoking status, operation time, a bedridden or paralyzed state, the presence of a tumor, postoperative dehydration, and glucocorticoid treatment, between the two groups (P < 0.05. The binary logistic regression analysis showed that an age greater than 50 years, hypertension, a bedridden or paralyzed state, the presence of a tumor, and postoperative dehydration were risk factors for lower extremity DVT in postoperative neurosurgical patients. Conclusions: Lower extremity DVT was a common complication following craniotomy in the enrolled Chinese neurosurgical

    Chronic myelomonocytic leukemia (CMML) is a myelodysplastic/myeloproliferative neoplasm with variable clinical course. To predict the clinical outcome, we previously developed a CMML-specific prognostic scoring system (CPSS) based on clinical parameters and cytogenetics. In this work, we tested the hypothesis that accounting for gene mutations would further improve risk stratification of CMML patients. We therefore sequenced 38 genes to explore the role of somatic mutations in disease phenotype and clinical outcome. Overall, 199 of 214 (93%) CMML patients carried at least 1 somatic mutation. Stepwise linear regression models showed that these mutations accounted for 15% to 24% of variability of clinical phenotype. Based on multivariable Cox regression analyses, cytogenetic abnormalities and mutations in RUNX1, NRAS, SETBP1, and ASXL1 were independently associated with overall survival (OS). Using these parameters, we defined a genetic score that identified 4 categories with significantly different OS and cumulative incidence of leukemic evolution. In multivariable analyses, genetic score, red blood cell transfusion dependency, white blood cell count, and marrow blasts retained independent prognostic value. These parameters were included into a clinical/molecular CPSS (CPSS-Mol) model that identified 4 risk groups with markedly different median OS (from >144 to 18 months, hazard ratio [HR] = 2.69) and cumulative incidence of leukemic evolution (from 0% to 48% at 4 years, HR = 3.84) (P < .001). The CPSS-Mol fully retained its ability to risk stratify in an independent validation cohort of 260 CMML patients. In conclusion, integrating conventional parameters and gene mutations significantly improves risk stratification of CMML patients, providing a robust basis for clinical decision-making and a reliable tool for clinical trials.

    Objectives: The purpose of this study was to determine the incidence and clinical symptoms associated with sharp mandibular bone irregularities (SMBI) after lower third molar extraction and to identify possible risk factors for this complication. Study Design: A mixed study design was used. A retrospective cohort study of 1432 lower third molar extractions was done to determine the incidence of SMBI and a retrospective case-control study was done to determine potential demographic and etiologic factors by comparing those patients with postoperative SMBI with controls. Results: Twelve SMBI were found (0.84%). Age was the most important risk factor for this complication. The operated side and the presence of an associated radiolucent image were also significantly related to the development of mandibular bone irregularities. The depth of impaction of the tooth might also be an important factor since erupted or nearly erupted third molars were more frequent in the SMBI group. Conclusions: SMBI are a rare postoperative complication after lower third molar removal. Older patients having left side lower third molars removed are more likely to develop this problem. The treatment should be the removal of the irregularity when the patient is symptomatic. Key words:Third molar, postoperative complication, bone irregularities, age. PMID:23524429

    Intracerebral hemorrhage (ICH) is the second most common subtype of stroke and a critical disease usually leading to severe disability or death. ICH is more common in Asians, advanced age, male sex, and low- and middle-income countries. The case fatality rate of ICH is high (40% at 1 month and 54% at 1 year), and only 12% to 39% of survivors can achieve long-term functional independence. Risk factors of ICH are hypertension, current smoking, excessive alcohol consumption, hypocholesterolemia, and drugs. Old age, male sex, Asian ethnicity, chronic kidney disease, cerebral amyloid angiopathy (CAA), and cerebral microbleeds (CMBs) increase the risk of ICH. Clinical presentation varies according to the size and location of hematoma, and intraventricular extension of hemorrhage. Patients with CAA-related ICH frequently have concomitant cognitive impairment. Anticoagulation related ICH is increasing recently as the elderly population who have atrial fibrillation is increasing. As non-vitamin K antagonist oral anticoagulants (NOACs) are currently replacing warfarin, management of NOAC-associated ICH has become an emerging issue. PMID:28178408

    Full Text Available Acute kidney injury (AKI is frequently seen in Hemiscorpius lepturus scorpion stung children. We have previously reported several victims with hemolytic uremic syndrome (HUS and a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 deficiency. Hence, we conducted this study to identify predictive factors and clinical features of AKI in H. lepturus scorpion stung patients. We included all 215 H. lepturus scorpion stung children with no previous renal diseases in two groups (with and without AKI and compared them based on their clinical and laboratory findings. AKI was found in 27.4% of patients, they were significantly younger and with lower body weight (P = 0.006, P = 0.011, respectively. There was a significant difference between groups with and without AKI in findings such as fever (P = 0.003, hypertension (P <0.001, hemolytic anemia (P <0.001, thrombocytopenia (P <0.001, massive proteinuria (P <0.001, hemoglobinuria (P <0.001, pyuria (P <0.001, and hematuria (P = 0.004. HUS was in 5.5% and disseminated intravascular coagulation in 14.6% which had a significant association with AKI (P <0.001.There were several independent predictors for AKI in a multivariate regression model including thrombocytopenia (P = 0.002, pyuria (P = 0.01, proteinuria (P =0.01, and fever (P = 0.02. Hemodialysis was performed in four patients but kidney function improved in all patients and there was no findings of renal impairment after three months follow-up. We found several predictors for AKI in children following H. lepturus scorpion sting including younger age, delay in receiving medical care, pigmenturia, microangiopathic hemolytic anemia, proteinuria, and pyuria.

    2015-01-01

    Pancreaticobiliary junction is composed of complexstructure with which biliary duct and pancreatic ductassemble and go out into the ampulla of Vater duringduodenum wall surrounding the sphincter of Oddi.Although the sphincter of Oddi functionally preventsthe reflux of pancreatic juice, pancreaticobiliary reflux(PBR) occurs when function of the sphincter of Oddihalt. The anatomically abnormal junction is termedpancreaticobiliary maljunction (PBM) and is characterizedby pancreatic and bile ducts joining outside of theduodenal wall. PBM is an important anatomical findingbecause many studies have revealed that biliarymalignancies are related due to the carcinogenetic effectof the pancreatic back flow on the biliary mucosa. Onthe other hand, several studies have been published onthe reflux of pancreatic juice into the bile duct withoutmorphological PBM, and the correlation of such caseswith biliary diseases, especially biliary malignancies, isdrawing considerable attention. Although it has longbeen possible to diagnose PBM by various imagingmodalities, PBR without PBM has remained difficult toassess. Therefore, the pathological features of PBRwithout PBM have not been yet fully elucidated. Lately,a new method of diagnosing PBR without PBM hasappeared, and the features of PBR without PBM shouldsoon be better understood.

    Full Text Available OBJECTIVE: To investigate the clinical features, outcome, and risk factors of disease flares in patients with pregnancy-related lupus (PRL. METHODS: Medical charts of 155 consecutive PRL inpatients were systematically reviewed, including demographic data, clinical features, laboratory findings, treatment, complications, and outcome. RESULTS: PRL cases were divided into active (a-PRL (n = 82, 53.0% and stable lupus (s-PRL (n = 73, 47.0%. Compared with nonpregnant active female systemic lupus erythematosus (SLE patients, a-PRL including new-onset lupus (n-PRL and flare lupus (f-PRL (n = 41 respectively, had a higher incidence of renal and hematological involvement but less mucocutaneous and musculoskeletal involvement (p<0.05. The incidence of preeclampsia/eclampsia, fetal loss, and preterm birth were significantly higher in a-PRL than in s-PRL (p<0.05. Despite receiving a more vigorous glucocorticoid treatment, a-PRL mothers had a poorer prognosis (p<0.001. Five (6.1% of them died and 13 (15.9% developed severe irreversible organ failure, whereas none of these events was observed in the s-PRL group. Multivariate logistic analysis indicated that a history of lupus flares and serological activity (hypocomplementemia and/or anti-dsDNA positivity at the time of conception were associated with lupus flares in PRL mothers. CONCLUSIONS: SLE patients with a flare history and serological activity at the time of conception were at an increased risk of disease flares during pregnancy and puerperium. a-PRL patients were more prone to renal and hematological involvement, pregnancy complications, and a poorer prognosis despite more vigorous glucocorticoid treatment.

    Full Text Available Idiosyncratic drug-induced liver injury (DILI caused by xenobiotics (drugs, herbals and dietary supplements presents with a range of both phenotypes and severity, from acute hepatitis indistinguishable of viral hepatitis to autoimmune syndromes, steatosis or rare chronic vascular syndromes, and from asymptomatic liver test abnormalities to acute liver failure. DILI pathogenesis is complex, depending on the interaction of drug physicochemical properties and host factors. The awareness of risk factors for DILI is arising from the analysis of large databases of DILI cases included in Registries and Consortia networks around the world. These networks are also enabling in-depth phenotyping with the identification of predictors for severe outcome, including acute liver failure and mortality/liver transplantation. Genome wide association studies taking advantage of these large cohorts have identified several alleles from the major histocompatibility complex system indicating a fundamental role of the adaptive immune system in DILI pathogenesis. Correct case definition and characterization is crucial for appropriate phenotyping, which in turn will strengthen sample collection for genotypic and future biomarkers studies.

    Fumiaki Sato

    Full Text Available Barrett's esophagus predisposes to esophageal adenocarcinoma. However, the value of endoscopic surveillance in Barrett's esophagus has been debated because of the low incidence of esophageal adenocarcinoma in Barrett's esophagus. Moreover, high inter-observer and sampling-dependent variation in the histologic staging of dysplasia make clinical risk assessment problematic. In this study, we developed a 3-tiered risk stratification strategy, based on systematically selected epigenetic and clinical parameters, to improve Barrett's esophagus surveillance efficiency.We defined high-grade dysplasia as endpoint of progression, and Barrett's esophagus progressor patients as Barrett's esophagus patients with either no dysplasia or low-grade dysplasia who later developed high-grade dysplasia or esophageal adenocarcinoma. We analyzed 4 epigenetic and 3 clinical parameters in 118 Barrett's esophagus tissues obtained from 35 progressor and 27 non-progressor Barrett's esophagus patients from Baltimore Veterans Affairs Maryland Health Care Systems and Mayo Clinic. Based on 2-year and 4-year prediction models using linear discriminant analysis (area under the receiver-operator characteristic (ROC curve: 0.8386 and 0.7910, respectively, Barrett's esophagus specimens were stratified into high-risk (HR, intermediate-risk (IR, or low-risk (LR groups. This 3-tiered stratification method retained both the high specificity of the 2-year model and the high sensitivity of the 4-year model. Progression-free survivals differed significantly among the 3 risk groups, with p = 0.0022 (HR vs. IR and p<0.0001 (HR or IR vs. LR. Incremental value analyses demonstrated that the number of methylated genes contributed most influentially to prediction accuracy.This 3-tiered risk stratification strategy has the potential to exert a profound impact on Barrett's esophagus surveillance accuracy and efficiency.

    BACKGROUND: The 2011 American Heart Association Guidelines on the management of asymptomatic carotid disease recommends that carotid endarterectomy (CEA) (with carotid artery stenting (CAS) as an alternative) may be considered in highly selected patients with 70-99% stenoses. However, no guidance...... was provided as to what "highly selected" meant. This caveat is, however, important as up to 95% of asymptomatic individuals undergoing prophylactic CEA or CAS will ultimately undergo an unnecessary procedure. Even if the procedural risk following CEA or CAS could be reduced to 0%; 93% of patients would still....../CAS. METHODS: Review of clinical and/or imaging based scoring systems, predictive algorithms and imaging parameters that may be associated with an increased (or decreased) risk of stroke in patients with asymptomatic carotid disease. RESULTS: Parameters associated with an increased risk of late stroke include...

    2014-01-01

    Full Text Available Osteogenesis imperfecta (OI is a rare hereditary condition caused by changes in collagen metabolism. It is classified into four types according to clinical, genetic, and radiological criteria. Clinically, bone fragility, short stature, blue sclerae, and locomotion difficulties may be observed in this disease. OI is often associated to severe dental problems, such as dentinogenesis imperfecta (DI and malocclusions. Radiographically, affected teeth may have crowns with bulbous appearance, accentuated constriction in the cementoenamel junction, narrowed roots, large root canals due to defective dentin formation, and taurodontism (enlarged pulp chambers. There is no definitive cure, but bisphosphonate therapy is reported to improve bone quality; however, there is a potential risk of bisphosphonate-related osteonecrosis of the jaw. In this study we report a case of OI in a male pediatric patient with no family history of OI who was receiving ongoing treatment with intravenous perfusion of bisphosphonate and who required dental surgery. In addition, we discussed the clinical and imaging findings and briefly reviewed the literature.

    Full Text Available Background: Nosocomial meningitis is a rare complication following neurosurgical procedures and is associated with high morbidity and mortality. Aim: The aim of this study was to describe the clinical characteristics and the risk factors associated with mortality in patients who developed nosocomial meningitis following neurosurgical operations. Setting and design: Tertiary care hospital and an observational study. Materials and Methods: The study subjects included 2265 patients who underwent various neurosurgical operations during 2003-05. The diagnosis of nosocomial meningitis was based on the Center for Disease Control criteria. Statistical analysis: It was performed by using Statistical Package for Social Sciences for Windows 10.0 program. Results: The incidence of postoperative nosocomial meningitis was 2.7% (62 episodes in 49 patients among 2265 patients operated. Staphylococcus aureus and Acinetobacter spp. were the most frequently isolated pathogens. Of the 49 with meningitis 20 (40.8% patients died. In the logistic regression analysis model, Glascow coma scale score less than 10 (Odds Ratio (OR: 19.419, 95% Confidence Interval (CI; 1.637-230.41, P = 0.001, and low cerebrospinal fluid glucose level (≤ 30 mg/ dL (OR: 10.272, 95% CI; 1.273-82.854, P = 0.002, and presence of concurrent nosocomial infection (OR: 28.744, 95% CI;1.647-501.73, P =0.001 were the independent risk factors associated with mortality. Conclusion: The mortality in patients who developed meningitis was high. The high percentage of concurrent nosocomial infections was associated with a high mortality rate which was a serious problem.

  7. Renal disease in adult Nigerians with sickle cell anemia: A report of prevalence, clinical features and risk factors

    Full Text Available Renal abnormalities in adult Nigerians with sickle cell anemia (SCA have not been extensively studied. To determine the prevalence, pattern and the associated risk factors of renal disease, 72 subjects with SCA from two centers in the southwestern Nigeria were investigated. Socio-demographic data, body mass index and clinical findings were documented. The urine analysis, serum bio-chemistry, hemogram and renal factors attributable to SCA were determined. Presence of albuminuria of at least 1+ or microalbuminuria in those negative with dipstick; and the estimated glomerular filtration rate (eGFR using the Cockcroft-Gault formula categorized subjects to various stages of chronic kidney disease (CKD. Subjects with and without albuminuria were compared to determine the relative risk associated with renal disease. Four (5.6% subjects had macro-albuminuria, while 32 (44.4% had micro-albuminuria and 30 (41.7% had hemoglobinuria. In the subjects with albuminuria, age, hematocrit, systolic blood pressure, serum creatinine, urea and creatinine clearance were numerically higher while the eGFR was numerically lower. There was no significant difference in the clinical parameters studied in the two groups of subjects. The diastolic blood pressure was significantly higher in the albuminuric group. Based on eGFR, 22 (30.6% subjects had hyperfiltration (GFR > 140 mL/min/1.73 m2, of whom 36.4% had albuminuria, 18 (25.0% had stage 1 CKD, 30 (41.7% had stage 2 CKD and two (2.7% subjects had stage 3 CKD with albuminuria. None had stage 4 and 5 CKD. We conclude that renal abnormalities, importantly albuminuria, is common in adult Nigerians with SCA and the pattern and incidence are similar to those reported from other parts of the world. Regular blood pressure monitoring, early diagnosis and active intervention are advocated to delay progression to end-stage kidney disease in view of poor outcomes of renal replacement therapy in SCA patients with nephropathy.

    Thyroid cancer (TC) is the second most common cancer among Hispanic women. Recent genome-wide association (GWA) and candidate studies identified 6 single nucleotide polymorphisms (SNPs; rs966423, rs2439302, rs965513, rs6983267, rs944289, and rs116909374), associated with increased TC risk in Europeans but their effects on disease risk have not been comprehensively tested in Hispanics. In this study, we aimed to describe the main clinicopathological manifestations and to evaluate the effects of known SNPs on TC risk and on clinicopathological manifestations in a Hispanic population.We analyzed 281 nonmedullary TC cases and 1146 cancer-free controls recruited in a multicenter population-based study in Colombia. SNPs were genotyped by Kompetitive allele specific polymerase chain reaction (KASP) technique. Association between genetic variants and TC risk was assessed by computing odds ratios (OR) and confidence intervals (CIs).Consistent with published data in U.S. Hispanics, our cases had a high prevalence of large tumors (>2 cm, 43%) and a high female/male ratio (5:1). We detected significant associations between TC risk and rs965513A (OR = 1.41), rs944289T (OR = 1.26), rs116909374A (OR = 1.96), rs2439302G (OR = 1.19), and rs6983267G (OR = 1.18). Cases carried more risk alleles than controls (5.16 vs. 4.78, P = 4.8 × 10). Individuals with ≥6 risk alleles had >6-fold increased TC risk (OR = 6.33, P = 4.0 × 10) compared to individuals with ≤2 risk alleles. rs944289T and rs116909374A were strongly associated with follicular histology (ORs = 1.61 and 3.33, respectively); rs2439302G with large tumors (OR = 1.50); and rs965513A with regional disease (OR = 1.92).To our knowledge, this is the first study of known TC risk variants in South American Hispanics and suggests that they increase TC susceptibility in this population and can identify patients at higher risk of severe disease.

    Full Text Available Background. There is a paucity of research in Australia on the characteristics of women in treatment for illicit substance use in pregnancy and the health outcomes of their neonates. Aims. To determine the clinical features and outcomes of high-risk, marginalized women seeking treatment for illicit substance use in pregnancy and their neonates. Methods. 139 women with a history of substance abuse/dependence engaged with a perinatal drug health service in Sydney, Australia. Maternal (demographic, drug use, psychological, physical, obstetric, and antenatal care and neonatal characteristics (delivery, early health outcomes were examined. Results. Compared to national figures, pregnant women attending a specialist perinatal and family drug health service were more likely to report being Australian born, Aboriginal or Torres Strait Islander, younger, unemployed, and multiparous. Opiates were the primary drug of concern (81.3%. Pregnancy complications were common (61.9%. Neonates were more likely to be preterm, have low birth weight, and be admitted to special care nursery. NAS was the most prevalent birth complication (69.8% and almost half required pharmacotherapy. Conclusion. Mother-infant dyads affected by substance use in pregnancy are at significant risk. There is a need to review clinical models of care and examine the longer-term impacts on infant development.

    The 2013–2016 outbreak of Ebola virus disease (EVD) in West Africa infected >28,000 people, including >11,000 who died, and disrupted social life in the region. We retrospectively studied clinical signs and symptoms and risk factors for fatal outcome among 31 Ebola virus–positive patients admitted to the Ebola Treatment Center in Moyamba District, Sierra Leone. We found a higher rate of bleeding manifestations than reported elsewhere during the outbreak. Significant predictors for death were shorter time from symptom onset to admission, male sex, high viral load on initial laboratory testing, severe pain, diarrhea, bloody feces, and development of other bleeding manifestations during hospitalization. These risk factors for death could be used to identify patients in need of more intensive medical support. The lack of fever in as many as one third of EVD cases may have implications for temperature-screening practices and case definitions. PMID:27268303

    2010-03-01

    Neurotoxicity from intravenous fludarabine is a rare but recognized clinical entity. Its brain imaging features have not been extensively described. Three patients received 38.5 mg or 40 mg/m per day fludarabine in a 5-day intravenous infusion before bone marrow transplantation in treatment of hematopoietic malignancies. Several weeks later, each patient developed progressive neurologic decline, including retrogeniculate blindness, leading to coma and death. Brain MRI showed progressively enlarging but mild T2/FLAIR hyperintensities in the periventricular white matter. The lesions demonstrated restricted diffusion but did not enhance. Because the neurotoxicity of fludarabine appears long after exposure, neurologic decline in this setting is likely to be attributed to opportunistic disease. However, the imaging features are distinctive in their latency and in being mild relative to the profound clinical features. The safe dose of fludarabine in this context remains controversial.

    Only a few studies provided data on the clinical history of sepsis within internal Medicine units. The aim of the study was to assess the short-term mortality and to evaluate the prognostic risk factors in a large cohort of septic patients treated in internal medicine units. Thirty-one internal medicine units participated to the study. Within each participating unit, all admitted patients were screened for the presence of sepsis. A total of 533 patients were included; 78 patients (14.6%, 95%CI 11.9, 18.0%) died during hospitalization; mortality rate was 5.5% (95% CI 3.1, 9.6%) in patients with nonsevere sepsis and 20.1% (95%CI 16.2, 28.8%) in patients with severe sepsis or septic shock. Severe sepsis or septic shock (OR 4.41, 95%CI 1.93, 10.05), immune system weakening (OR 2.10, 95%CI 1.12, 3.94), active solid cancer (OR 2.14, 95% CI 1.16, 3.94), and age (OR 1.03 per year, 95% CI 1.01, 1.06) were significantly associated with an increased mortality risk, whereas blood culture positive for Escherichia coli was significantly associated with a reduced mortality risk (OR 0.46, 95%CI 0.24, 0.88). In-hospital mortality of septic patients treated in internal medicine units appeared similar to the mortality rate obtained in recent studies conducted in the ICU setting.

    Approximately 36.5% of the U.S. adults (≥ 20 years old) are obese. Obesity has been associated with type 2 diabetes mellitus, cardiovascular disease, stroke, and several types of cancer. The present study included 1788 prostate cancer patients who were treated with radical prostatectomy at the Ochsner Health System, New Orleans, Louisiana, from January, 2001 to March, 2016. The patient’s medical records were retrospectively reviewed. Body mass index (BMI), age, ethnicity (Caucasians versus African Americans), clinical stage, Gleason score, and prostate-specific antigen (PSA) levels were retrieved. The relative risk of the patients was stratified into low risk and high risk groups. Associative analyses found that BMI was associated with age, clinical stage, Gleason score, but not ethnicity, PSA levels, or the relative risk in this cohort. Age was associated with ethnicity, clinical stage, Gleason score, and PSA levels, as well as the relative risk. Ethnicity was associated with Gleason score and PSA levels as well as the relative risk, but not clinical stage. These findings suggest that obesity is associated with advanced prostate cancer with stage T3 or Gleason score ≥ 7 diseases, and age and ethnicity are important factors that are associated with the clinical features of prostate cancer patients.

    Full Text Available Abstract Background The purpose of the present study was to evaluate the prognostic value of POSTN expression following prostatectomy. Methods Periostin (POSTN expression in prostate cancer (PCa and in normal specimens was evaluated in 90 patients by an immuno-reactive score(IRS based on the intensity of immunostaining and on the quantity of stained cells. The t-test was applied to compare IRS values in cancer specimens to values in normal specimens. Pearson’s test was used to correlate POSTN expression to clinical pathologic features. PSA progression-free and survival curves were constructed by the Kaplan–Meier method and compared using the log-rank test. Multi-parametric models were constructed according to the Cox technique adding all the covariates predicting for either PSA progression or death into the models after univariate analysis. Results Both stromal and epithelial POSTN expression were significantly increased in tumor tissues. In particular, we found stromal expression to be significantly higher than epithelial expression as compared to normal tissues (p Conclusions Although requiring further validation through larger studies, our findings show that POSTN might represent a novel prognostic marker for PCa.

    2014-05-01

    The term 'neuromyelitis optica' ('Devic's syndrome', NMO) refers to a syndrome characterized by optic neuritis and myelitis. In recent years, the condition has raised enormous interest among scientists and clinical neurologists, fuelled by the detection of a specific serum immunoglobulin (Ig)G reactivity (NMO-IgG) in up to 80% of patients with NMO. These autoantibodies were later shown to target aquaporin-4 (AQP4), the most abundant water channel in the central nervous system (CNS). Here we give an up-to-date overview of the clinical and paraclinical features, immunopathogenesis and treatment of NMO. We discuss the widening clinical spectrum of AQP4-related autoimmunity, the role of magnetic resonance imaging (MRI) and new diagnostic means such as optical coherence tomography in the diagnosis of NMO, the role of NMO-IgG, T cells and granulocytes in the pathophysiology of NMO, and outline prospects for new and emerging therapies for this rare, but often devastating condition.

    Objective To evaluate the clinical and pathological features of Riedel's thyroiditis (RT), and current diagnostic and treatment methods for that disease.Methods Five RT cases identified by surgery and pathological examinations at Peking Union Medi-cal College Hospital from 1985 to 2009 were analyzed and compared with the cases reported in the litera-ture in terms of clinical and pathological features. Immunohistochemical staining of kappa and lambda light chains was carried out for RT tissues from all the five patients.Results All the five cases were females, aged 45-55 years. Elevation of serum thyroid autoantibodies was found in only one patient, who had longer disease duration than the others. Pathological examination re-vealed invasive fibrosclerosis of the thyroid follicles, thyroid capsule, and the surrounding tissues. In RT tis-sues, the number of cells containing lambda chains was a little higher than those containing kappa chains.Conclusions RT is a rare disease which might be more common in middle-aged females than in other populations. Pathological features include the destruction of thyroid follicle, extension into surround-ing tissues by inflammatory cells and fibrous tissues. Immunohistochemical staining of kappa and lambda chains could help diagnose RT.

    Full Text Available Background: Intraocular medulloepithelioma arises from the primitive medullary epithelium and is diagnosed at a median age of five years. This tumor most commonly appears as a white, gray, or yellow-colored ciliary body tumor. The growth of medulloepithelioma is slow and it is locally invasive. Poor vision and pain are the most common presenting symptoms. The most common clinical signs include cyst or mass in iris, anterior chamber or ciliary body, glaucoma, and cataract. Case: A 22-month-old Caucasian female twin presented with leukocoria and poor vision in OS. Examination revealed normal findings OD and a mass in OS. Based on the clinical features of leukocoria, lens changes and a white cystic ciliary body mass in a young child, ultrasonographic, and transillumination features, the lesion was diagnosed as a non-pigmented ciliary epithelial medulloepithelioma. After enucleation, the diagnosis of malignant teratoid medulloepithelioma of the non-pigmented ciliary epithelium was confirmed. There was no evidence of tumor recurrence or systemic metastasis at three years follow-up. Conclusion: Medulloepithelioma in a child can present as a clinical triad of leukocoria, lens changes, and a white cystic ciliary body mass.

    The purpose of this study is to evaluate the CT findings and clinical features of patients with pneumatosis intestinalis. From January 2001 to October 2007, 15 patients with pneumatosis intestinalis were diagnosed by the use of CT. We analyzed the clinical features and CT findings to assess the involvement site, the presence of portal and mesenteric vein gas, and the existence of accompanied ischemic change. Of the 15 patients, five patients had end stage renal disease (33.3%), two patients underwent a gastrectomy, one patient underwent a laminectomy, one patient had tuberculous enteritis, one patient had lung cancer and one patient had pneumonia. Four patients presented with no specific disease. There was portal or mesenteric venous gas in six cases, and strangulation or an ischemic change of the bowel in five cases. Otherwise, pneumatosis intestinalis was associated with hydropneumoperitoneum in two cases, pneumoperitoneum in one case and a single case of perforated appendicitis. Nine patients underwent surgery for ischemic change of the bowel, pneumoperitoneum, appendicitis, and a clinical sign of panperitonitis. Among the remaining six patients, three patients recovered and were discharged, and three patients expired during progression of the disease. End stage renal disease is the most common condition associated with pneumatosis intestinalis. The presence of portomesenteric venous gas, ischemic change of the bowel, and linear pneumatosis intestinalis are indicative of a poor prognosis.

    2013-02-01

    In this review, we delineate clinical, electrodiagnostic, and radiographic features of ulnar mononeuropathies. Ulnar neuropathy at the elbow (UNE) is most commonly due to lesions at the level of the retroepicondylar groove (RTC), with approximately 25% at the humeroulnar arcade (HUA). The term 'cubital tunnel syndrome' should be reserved for the latter. The diagnostic accuracy of nerve conduction studies is limited by biological (e.g. low elbow temperature) and technical factors. Across-elbow distance measurements greater than 10 cm improve diagnostic specificity at the expense of decreased sensitivity. Short-segment incremental studies can differentiate lesions at the HUA from those at the RTC.

    Objective: To establish the initial symptoms and physical signs of osteosarcoma from the records of the first medical visit and to identify early characteristics of the diseases to shorten the delay of diagnosis. Methods: A group of patients with osteosarcoma in extremities was identified from Nanjing Jinling Hospital. Records from the first medical visit due to symptoms and physical signs related to the bone tumor were obtained from 71 patients with osteosarcoma. Results: The results of the data recorded about the first medical visit,reasons for consultation, pain,trauma,initial diagnosis,delay in diagnosis were reported respectively. Conclusion: Pair an initial symptom of osteosarcoma, and was intermittent but not frequently felt at night. A history of trauma was common, but the clinical course often diverged from what was expected from trauma. The most important clinical feature was a palpable mass. This finding emphasizes that a thorough physical examination is absolutely necessary.

    have electrolyte disturbances like hyponatremia, hypokalemia, and metabolic alkalosis, associated with defective water handling or with diuretic use. Serum aminotransferases, alkaline phosphatase and gammaglutamyl transpeptidase are often abnormal in a nonspecific pattern. Some serum markers are useful in diagnosis of HCC. The most commonly used is alpha-fetoprotein (AFP. AFP is a glycoprotein that is normally produced during gestation by the fetal liver and the yolk sac.

    In adults, normal values are less than 20 ng/ml and AFP is often elevated in patients with HCC. Serum concentrations of AFP do not correlate with clinical features of HCC, such as size, stage and prognosis but is generally accepted that serum levels greater than 500 ng/ml in a high risk patient is diagnosis of HCC.

    Other serum markers - Because of the limitations of serum AFP measurements, other serum markers of HCC used alone or in combination with the serum AFP have been evaluated for diagnosis or determining prognosis in patients with HCC. These include lens culinaris agglutinin-reactive AFP and des-gamma carboxyprothrombin, glypican-3, human hepatocyte growth factor, and insulin-like growth factor.

    Objective To explore prospective diagnostic criteria for preleukemia.Methods A case control study was done comparing the discrepancies on clinical and laboratory features between patients with preleukemia and those with chronic aplastic anemia (CAA) or atypical paroxysmal nocturnal hemoglubinuria (a-PNH).Results There were eight variables of significance: (1) lymphocytoid micromegakaryocytes in the bone marrow; (2) immature granulocytes in the peripheral blood; (3) ≥2.0% myeloblasts in the bone marrow; (4) positive periodic acid schiff (PAS) stained nucleated erythrocytes; (5) myeloid differentiation index ≥1.8; (6) typical colonal karyotypic abnormalities; (7) negative sister chromatid differentiation; (8) cluster/colony ratio of granulocyte-macrophage colony-forming units (CFU-GM)>4.0. The following criteria were assigned: A: to meet variable one and at least two of the other seven variables and B: to meet at least four of the eight variables. All of the patients with preleukemia met either A or B and none of the patients with CAA or a-PNH did. Conclusions Preleukemia is different from CAA or a-PNH. It has its own clinical and laboratory features, which may be useful for its prospective diagnosis.

    Autoimmune uveitis (AU), an inflammatory non-infectious process of the vascular layer of the eye, can lead to visual impairment and, in the absence of a timely diagnosis and suitable therapy, can even result in total blindness. The majority of AU cases are idiopathic, whereas fewer than 20 % are associated with systemic diseases. The clinical severity of AU depends on whether the anterior, intermediate, or posterior part of the uvea is involved and may range from almost asymptomatic to rapidly sight-threatening forms. Race, genetic background, and environmental factors can also influence the clinical picture. The pathogenetic mechanism of AU is still poorly defined, given its remarkable heterogeneity and the many discrepancies between experimental and human uveitis. Even so, the onset of AU is thought to be related to an aberrant T cell-mediated immune response, triggered by inflammation and directed against retinal or cross-reactive antigens. B cells may also play a role in uveal antigen presentation and in the subsequent activation of T cells. The management of AU remains a challenge for clinicians, especially because of the paucity of randomized clinical trials that have systematically evaluated the effectiveness of different drugs. In addition to topical treatment, several different therapeutic options are available, although a standardized regimen is thus far lacking. Current guidelines recommend corticosteroids as the first-line therapy for patients with active AU. Immunosuppressive drugs may be subsequently required to treat steroid-resistant AU and for steroid-sparing purposes. The recent introduction of biological agents, such as those targeting tumor necrosis factor-α, is expected to remarkably increase the percentages of responders and to prevent irreversible sight impairment. This paper reviews the clinical features of AU and its crucial pathogenetic targets in relation to the current therapeutic perspectives. Also, the largest clinical trials

    Pachyonychia congenita (PC) is a rare genodermatosis affecting the nails, skin, oral mucosae, larynx, hair, and teeth. Pathogenic mutations in keratins K6a or K16 are associated with the PC-1 phenotype whereas K6b and K17 mutations are associated with the PC-2 phenotype. Analysis of clinical, pathological, and genetic data from the literature and two research registries reveal that >97% of PC cases exhibit fingernail and toenail thickening, and painful plantar keratoderma. Prospective evaluation of 57 PC patients from 41 families revealed variable clinical findings: hyperhidrosis (79%), oral leukokeratosis (75%), follicular keratosis (65%), palmar keratoderma (60%), cutaneous cysts (35%), hoarseness or laryngeal involvement (16%), coarse or twisted hair (26%), early primary tooth loss (14%), and presence of natal or prenatal teeth (2%). Stratification of these data by keratin mutation confirmed the increased incidence of cyst formation and natal teeth among PC-2 patients, although cysts were more commonly seen in PC-1 than previously reported (25%-33%). Previously unreported clinical features of PC include development of painful oral and nipple lesions during breastfeeding, copious production of waxy material in ears, and inability to walk without an ambulatory aid (50%). Possible pathogenic mechanisms are discussed with respect to the clinicopathologic and genetic correlations observed.

    Full Text Available Abstract Background 2009 pandemic H1N1 (pH1N1 influenza posed an increased risk of severe illness among pregnant women. Data on risk factors associated with death of pregnant women and neonates with pH1N1 infections are limited outside of developed countries. Methods Retrospective observational study in 394 severe or critical pregnant women admitted to a hospital with pH1N1 influenza from Sep. 1, 2009 to Dec. 31, 2009. rRT-PCR testing was used to confirm infection. In-hospital mortality was the primary endpoint of this study. Univariable logistic analysis and multivariate logistic regression analysis were used to investigate the potential factors on admission that might be associated with the maternal and neonatal mortality. Results 394 pregnant women were included, 286 were infected with pH1N1 in the third trimester. 351 had pneumonia, and 77 died. A PaO2/FiO2 ≤ 200 (odds ratio (OR, 27.16; 95% confidence interval (CI, 2.64-279.70 and higher BMI (i.e. ≥ 30 on admission (OR, 1.26; 95% CI, 1.09 to 1.47 were independent risk factors for maternal death. Of 211 deliveries, 146 neonates survived. Premature delivery (OR, 4.17; 95% CI, 1.19-14.56 was associated neonatal mortality. Among 186 patients who received mechanical ventilation, 83 patients were treated with non-invasive ventilation (NIV and 38 were successful with NIV. The death rate was lower among patients who initially received NIV than those who were initially intubated (24/83, 28.9% vs 43/87, 49.4%; p = 0.006. Septic shock was an independent risk factor for failure of NIV. Conclusions Severe hypoxemia and higher BMI on admission were associated with adverse outcomes for pregnant women. Preterm delivery was a risk factor for neonatal death among pregnant women with pH1N1 influenza infection. NIV may be useful in selected pregnant women without septic shock.

    Full Text Available Introduction In this study, the clinical features, underlying diseases and clinical outcomes of patients with cryptococcosis were investigated. In addition, a molecular analysis of the Cryptococcus neoformans species complex isolated from these patients was performed. Methods A prospective study of 62 cases of patients with cryptococcal infection was conducted at the Hospital de Doenças Tropicais de Goiás Dr. Anuar Auad from 2009-2010. Cryptococcal meningitis cases were diagnosed by direct examination and cerebrospinal fluid (CSF sample culture. The profiling of these patients was assessed. The CSF samples were submitted to India ink preparation and cultured on Sabouraud dextrose agar, and C. neoformans was identified by the production of urease, a positive phenoloxidase test and assimilation of carbohydrates. C. neoformans and C. gattii isolates were distinguished by growth on L-canavanine-glycine-bromothymol blue medium, and molecular analysis was conducted via PCR fingerprinting reactions using M13 and (GACA4 primers. Results From the 62 patients with cryptococcosis, 71 isolates of CSF were obtained; 67 (94.4% isolates were identified as C. neoformans var. grubii/VNI, and 4 (5.6% were identified as C. gattii/VGII. Of these patients, 53 had an HIV diagnosis. The incidence of cryptococcosis was higher among patients 20-40 years of age, with 74.2% of the cases reported in males. Cryptococcus-related mortality was noted in 48.4% of the patients, and the symptoms were altered sensorium, headache, fever and stiff neck. Conclusions The high morbidity and mortality observed among patients with cryptococcosis demonstrate the importance of obtaining information regarding the epidemiological profile and clinical course of the disease in the State of Goiás, Brazil.

    Suicide is a leading cause of death among adolescents and suicidal behavior is one of the primary risk factors for youth psychiatric hospitalizations. A number of studies indicate that depression and substance abuse are associated with suicide risk in this population, but less is known about the role of borderline personality features or their incremental influence over other known risk factors in indicating suicidal behavior among adolescents. This study examined whether borderline features were associated with suicide risk when controlling for symptoms of depression and substance abuse in a sample of adolescents hospitalized in an inpatient psychiatric facility. Self-report data from 477 adolescent psychiatric inpatients were used to test hypotheses about the association of borderline features with suicide risk after controlling for other common risk factors. Borderline features were significantly related to suicide risk even after accounting for symptoms of depression and substance abuse. These findings underscore the clinical value of routinely assessing borderline features among adolescents.

    A few authors have described the clinical picture of dysthymia in groups of elderly patients and pointed out differences from literature reports of dysthymia in younger adults. The present study, an attempt to analyze age effects on clinical characteristics of dysthymia throughout a lifetime, was performed in a sample of 106 patients, all aged > or =18 years, who were diagnosed according to DSM-IV. The patients were evaluated using: (1) a semistructured interview to assess clinical features, family history and previous treatments; (2) the Hamilton Depression Rating Scale; (3) the Interview for Recent Life Events; and (4) the Structured Clinical Interview for DSM-IV Disorders. Statistical analysis with stepwise logistic regression revealed that age was positively related to concomitant medical illnesses and to the total score of recent life events, but negatively related to the presence of avoidant or dependent personality disorders. The data suggested different etiologic pathways in older and younger patients. Dysthymia appeared to be associated in younger adults with abnormalities of personality; in the elderly, with a history of health problems and life losses.

    Objective To investigate the clinical pathological feature and diagnostic criteria of tongue amyloidosis (AL).Methods During 1992 to 2005, 25 patients pathologically diagnosed as tongue AL in our hospital were reviewed retrospectively, and all of them had no enlarged tongue. Haematoxylin and eosin (HE) and immunohistochemical staining were used to detect the amyloid deposition on the tongue.Results Totally 84 % (21/25) patients had symptoms of xerostomia and taste-blindness, 44 % (11/25) patients complained of activity limitation of tongue. Macroscopic observation showed mucosa pallescence, punctuate hemorrhage, red grain particles, and ulcers on the tongue. HE staining indicated amyloid depositions in basement membrane,muscle cell, vessel wall, and nerve fiber. Immunohistochemical study demonstrated kappa light-chain deposition in 64%(16/25) cases, and lambda light-chain deposition in 36 % (9/25) cases. They presented in vessel wall, nerve fiber, and muscle cells.Conclusion The biopsy is an important means for the diagnosis of early tongue AL, and the wide variety of amyloid light chain is helpful to differential diagnosis.

    We aimed to describe clinical and diagnostic features of vertebral osteomyelitis for differential diagnosis and treatment. This is a prospective observational study performed between 2002 and 2012 in Ankara Numune Education and Research Hospital in Ankara, Turkey. All the patients with vertebral osteomyelitis were followed for from 6 months to 3 years. In total, 214 patients were included in the study, 113 out of 214 (53%) were female. Out of 214 patients, 96 (45%) had brucellar vertebral osteomyelitis (BVO), 63 (29%) had tuberculous vertebral osteomyelitis (TVO), and 55 (26%) had pyogenic vertebral osteomyelitis (PVO). Mean number of days between onset of symptoms and establishment of diagnosis was greater with the patients with TVO (266 days) than BVO (115 days) or PVO (151 days, p 15 mm, sensitivity was 0.66, specificity was 0.97, positive predictive value was 0.89, negative predictive value was 0.88, and receiver operating characteristics area was 0.8. Tuberculous and brucellar vertebral osteomyelitis remained the leading causes of vertebral osteomyelitis with delayed diagnosis. In differential diagnosis of vertebral osteomyelitis, consumption of unpasteurized cheese, dealing with husbandry, sweating, arthralgia, hepatomegaly, elevated alanine transaminase, and lumbar involvement in magnetic resonance imaging were found to be predictors of BVO, thoracic involvement in magnetic resonance imaging and tuberculin skin test > 15 mm were found to be predictors of TVO, and history of spinal surgery and leucocytosis were found to be predictors of PVO.

    Full Text Available Objective: To assess the prevalence of Congenital Heart Block (CHB in newborns from anti Ro/SS-A antibodies positive mothers affected by connective tissue diseases (CTD and to evaluate the prevalence of other manifestations of Neonatal Lupus (NL and the electrocardiographic abnormalities. Methods: A prospective study was conducted on 100 anti Ro/SS-A positive mothers that were followed before and during their 118 pregnancies (4 twin pregnancies and 18 second pregnancies. Counterimmunoelectroforesis (CIE and immunoblot (IB were used to test antibodies to extractable nuclear antigens (ENA. Results: Only 2 cases of CHB (1.8% were found among the 112 living newborns. In one case the mother with primary Sjögren’s Syndrome (pSS was anti Ro 60 and 52kD positive while in the other case the mother affected by undifferentiated connective tissue disease (UCTD was anti Ro 60kD and anti La positive. No fetal death was due to CHB. There were no cutaneous rashes at birth while mild hepatic enzyme alterations were observed in 21 (68% of the 31 tested newborns. In 22 healthy newborns an ECG have been registered and in 4 cases (18.2% sinus bradycardia was found. During the follow up 7 suckling showed Cutaneous Neonatal Lupus. Moreover a six month girl developed Kawasaki Syndrome. Conclusions: The risk of delivering a child with CHB is 1.8% in anti Ro/SS-A positive mothers with CTD. This finding is extremely important in the preconceptional counseling of anti-Ro/SS-A positive women. Furthermore mild electrocardiographic abnormalities may be found in their healthy newborns.

They are the most common benign tumors in childhood. Recently, there have been significant, exciting advancements in the understanding of the pathogenesis and treatment of infantile hemangiomas, which are discussed in this review. The decision to initiate treatment for IH is based on many factors, including size and location, functional compromise, psychosocial implications, and risks and benefits of the proposed therapy. For most families of children with hemangiomas, education about the natural history of IH and reassurance are often the only "treatment" required. A minority of patients with large, complex lesions or lesions that cause functional compromise require early intervention. These patients and families benefit from a multidisciplinary approach to care in vascular birthmark centers. Ongoing multi-institutional clinical trials will provide further important data on the efficacy and safety of hemangioma treatments.Keywords: progenitor stem cell, glucose transporter 1, PHACES, LUMBAR, infantile hemangioma

    Full Text Available Non-alcoholic fatty liver disease (NAFLD is a cluster of pathological liver conditions of emerging importance in overweight and obese children. NAFLD is associated with central obesity, insulin resistance, and dyslipidaemia, which are considered to be the main features of metabolic syndrome (MetS. Prevention of the adverse outcomes of NAFLD, as well as the risk of MetS, depends on the identification of genetic background and environmental factors that modulate susceptibility to these diseases. However, several lines of evidence highlight the strong correlation and co-currency of these two chronic diseases, both in children and in adults. In the present review, we provide an overview of the current clinical proofs on the link between NAFLD and MetS in children, with particular focus on all the possible overlapping features that connect them at paediatric age.

    Background Cerebral hemorrhage is common in patients with cancer, but the clinical features and pathogenesis of liver cancer patients with cerebral hemorrhage are not well known. Material/Methods Liver cancer patients who developed cerebral hemorrhage were recruited from the First Affiliated Hospital of Guangxi Medical University between January 2003 and December 2014. We retrospectively analyzed clinical presentations, results of laboratory tests, and imaging examinations. The clinical features and pathogenesis were summarized. Results Among 11133 patients with liver cancer, 9 patients (0.08%), including 3 females and 6 males met the inclusion criteria. The age range was 48–73 years and the average age was 61.67±8.97 years. Five patients did not have traditional hemorrhage risk factors and 4s had the risk factors; however, all had developed hepatocellular carcinoma, and 3 had developed metastasis. All 9 patients showed elevated tumor markers: an increased AFP level was detected in 6 patients, coagulation dysfunctions in 8 patients, and abnormal liver functions in 6 patients. Five patients had developed cerebral hemorrhagic lesions in the lobes of their brains, while hemorrhagic lesions in the basal ganglia occurred in 3 patients and in the brainstem in only 1 patient. Four patients had clear consciousness, while 5 patients were in coma and showed poor prognosis. Conclusions Patients who have liver cancer complicated with cerebral hemorrhage usually lack traditional risk factors of cerebral hemorrhage. The site of cerebral hemorrhage is often detected in the lobes of the brain. Coagulation dysfunctions might be the main pathogenesis of liver cancer complicated with cerebral hemorrhage.

    Full Text Available Jacob HG Grand¹, Sienna Caspar², Stuart WS MacDonald11Department of Psychology, University of Victoria, Victoria, BC, Canada; 2Interdisciplinary Graduate Studies, University of British Columbia, Vancouver, BC, CanadaAbstract: Dementia is a clinical syndrome of widespread progressive deterioration of cognitive abilities and normal daily functioning. These cognitive and behavioral impairments pose considerable challenges to individuals with dementia, along with their family members and caregivers. Four primary dementia classifications have been defined according to clinical and research criteria: 1 Alzheimer’s disease; 2 vascular dementias; 3 frontotemporal dementias; and 4 dementia with Lewy bodies/Parkinson’s disease dementia. The cumulative efforts of multidisciplinary healthcare teams have advanced our understanding of dementia beyond basic descriptions, towards a more complete elucidation of risk factors, clinical symptoms, and neuropathological correlates. The characterization of disease subtypes has facilitated targeted management strategies, advanced treatments, and symptomatic care for individuals affected by dementia. This review briefly summarizes the current state of knowledge and directions of dementia research and clinical practice. We provide a description of the risk factors, clinical presentation, and differential diagnosis of dementia. A summary of multidisciplinary team approaches to dementia care is outlined, including management strategies for the treatment of cognitive impairments, functional deficits, and behavioral and psychological symptoms of dementia. The needs of individuals with dementia are extensive, often requiring care beyond traditional bounds of medical practice, including pharmacologic and non-pharmacologic management interventions. Finally, advanced research on the early prodromal phase of dementia is reviewed, with a focus on change-point models, trajectories of cognitive change, and threshold models of

    Context It has been reported that childhood psychotic symptoms are common in the general population and may signal neurodevelopmental processes that lead to schizophrenia. However, it is not clear whether these symptoms are associated with the same extensive risk factors established for adult schizophrenia. Objective To examine the construct validity of children’s self-reported psychotic symptoms by testing whether these symptoms share the risk factors and clinical features of adult schizophrenia. Design Prospective, longitudinal cohort study of a nationally representative birth cohort in Great Britain. Participants A total of 2232 twelve-year-old children followed up since age 5 years (retention, 96%). Main Outcome Measure Children’s self-reported hallucinations and delusions. Results Children’s psychotic symptoms are familial and heritable and are associated with social risk factors (eg, urbanicity); cognitive impairments at age 5; home-rearing risk factors (eg, maternal expressed emotion); behavioral, emotional, and educational problems at age 5; and comorbid conditions, including self-harm. Conclusions The results provide a comprehensive picture of the construct validity of children’s self-reported psychotic symptoms. For researchers, the findings indicate that children who have psychotic symptoms can be recruited for neuroscience research to determine the pathogenesis of schizophrenia. For clinicians, the findings indicate that psychotic symptoms in childhood are often a marker of an impaired developmental process and should be actively assessed. PMID:20368509

  3. The Clinical Features of Myositis-Associated Autoantibodies: a Review.

    The idiopathic inflammatory myopathies (IIM) are a group of autoimmune diseases traditionally defined by clinical manifestations including skeletal muscle weakness, skin rashes, elevated skeletal muscle enzymes, and neurophysiological and/or histological evidence of muscle inflammation. Patients with myositis overlap can develop other features including parenchymal lung disease, inflammatory arthritis, gastrointestinal manifestations and marked constitutional symptoms. Although patients may be diagnosed as having polymyositis (PM) or dermatomyositis (DM) under the IIM spectrum, it is quite clear that disease course between subgroups of patients is different. For example, interstitial lung disease may predominate in some, whereas cutaneous complications, cancer risk, or severe refractory myopathy may be a significant feature in others. Therefore, tools that facilitate diagnosis and indicate which patients require more detailed investigation for disease complications are invaluable in clinical practice. The expanding field of autoantibodies (autoAbs) associated with connective tissue disease (CTD)-myositis overlap has generated considerable interest over the last few years. Using an immunological diagnostic approach, this group of heterogeneous conditions can be separated into a number of distinct clinical phenotypes. Rather than diagnose a patient as simply having PM, DM or overlap CTD, we can define syndromes to differentiate disease subsets that emphasise clinical outcomes and guide management. There are now over 15 CTD-myositis overlap autoAbs found in patients with a range of clinical manifestations including interstitial pneumonia, cutaneous disease, cancer-associated myositis and autoimmune-mediated necrotising myopathy. This review describes their diagnostic utility, potential role in disease monitoring and response to treatment. In the future, routine use of these autoAb will allow a stratified approach to managing this complex set of conditions.

    Autoimmune hepatitis (AIH) is a chronic hepatitis of unknown etiology which can progress to cirrhosis.Its clinical manifestations are highly variable and sometimes follow a fluctuating course.Diagnosis is based on characteristic histologic,clinical,biochemical and serological findings. Anti-inflammatory/immunosuppressive treatment frequently induces remission but long-term maintenance therapy is often required. Liver transplantation is generally successful in patients with decompensated cirrhosis unresponsive to or intolerant of medical therapy.

    Full Text Available Considering the relevance of AIDS/tuberculosis comorbidity worldwide, especially in Brazil, this study was developed to describe the clinical and epidemiological features of the comorbid cases identified from 1989 to 1997 by the epidemiology service of the Hospital das Clínicas of the Universidade de São Paulo. METHODS: Databases containing information on all identified AIDS/tuberculosis cases cared for at the hospital were used to gather information on comorbid cases. RESULTS: During the period, 559 patients were identified as presenting with AIDS/tuberculosis comorbidity. Risk behavior for AIDS was primarily heterosexual contact (38.9%, followed by intravenous drug use (29.3% and homosexual/bisexual contact (23.2%. Regarding clinical features, there were higher rates of extrapulmonary tuberculosis when compared to tuberculosis without comorbidity. There was an increase in reporting of AIDS by ambulatory units during the period. Epidemiologically, there was a decrease in the male/female ratio, a predominance in the 20 to 39 year-old age group, and a majority of individuals who had less than 8 years of schooling and had low professional qualifications. CONCLUSIONS: High rates of AIDS/tuberculosis cases at our hospital indicate the need for better attention towards early detection of tuberculosis, especially in its extrapulmonary form. Since the population that attends this hospital tends to be of a lower socioeconomic status, better management of AIDS and tuberculosis is required to increase the rates of treatment adherence and thus lower the social costs.

    2015-11-01

    Cachexia is a clinically relevant syndrome which impacts on quality of life, morbidity and mortality of patients suffering from acute and chronic diseases. The hallmark of cachexia is muscle loss, which is triggered by disease-associated inflammatory response. Cachexia is a continuum and therefore a staging system is needed. Initially, a three-stage system (i.e. pre-cachexia, cachexia and refractory cachexia) was proposed. More recent evidence supports the use of a five-stage classification system, based on patient's BMI and severity of weight loss, to better predict clinical outcome. Also, large clinical trials in cancer patients demonstrated that cachexia emerging during chemotherapy has greater influence on survival than weight loss at baseline. Therefore, becoming widely accepted is the importance of routinely monitoring patients' nutritional status to detect early changes and diagnose cachexia in its early phases. Although cachexia is associated with the presence of anabolic resistance, it has been shown that sustained yet physiological hyperaminoacidaemia, as well as the use of specific nutrients, is able to overcome impaired protein synthesis and revert catabolism. More importantly, clinical evidence demonstrates that preservation of nutritional status during chemotherapy or improvement of body weight after weight loss is associated with longer survival in cancer patients.

    2008-12-01

    Full Text Available Introduction: The Syndrome of Sturge-Weber is a rare condition of congenital development, and is characterized by a neurocutaneous disorder with angiomas wrapping the leptomeninges and the face skin, mainly in the course of ophthalmic (V1 and maxillary (V2 branches of the trigeminal nerve. Objective: To review the literature about the Sturge-Weber Syndrome with emphasis on the current aspects. Method: The following databases were searched: EMedicine, Encyclopedia of Medicine, FindArticles, LILACS, MEDLINE, Merck Manuals On-Line Medical Library and Scielo, and the searches applied the terms: Sturge-Weber Syndrome, neurocutaneous syndromes, encephalo-trigeminal angiomatosis, nevus flammeus, in articles published between 1991 and 2007. Literature's Review: The most characteristic clinical statement is the presence, since the birth, of nevus flammeus, that generally reaches one half of the face and may stretch out up to the neck; in addition, other clinical manifestations may be present, like the corticocerebral angiomatosis, cerebral calcifications, epilepsy, ocular and buccal affections and mental retardation. The diagnosis is established by means of the inquiry of neurological and ophthalmic alterations in patients with a characteristic nevus flammeus, allied to the clinical data of complementary exams such as Computerized Tomography. The treatment consists basically of controlling the already confirmed clinical manifestations and preventing from the appearing of other alterations, mainly buccal and ocular. Conclusion: This syndrome is not much frequent, but it needs to be early diagnosed, since it brings a series of complications to its carriers when not treated, specially because of reaching the Nervous Central System. The health professionals have to be suitably able to recognize its characteristic signs and symptoms, and so improve the quality of life of these patients.

    Objective:To analyze the clinicopathological features and differential diagnosis of angiomyofibroblastoma(AMFB) of the vulva. Methods:Two cases of AMFB were examined by light microscopy and immunohistochemical study and to discuss the clinicopatholoical features and differential diagnosis of AMFB with the reference to the literature. Results:Tumors were all circumscribed,and<5 cm in diameter.Microscopically,the tumors were composed of spindle or polygonal cells that were cellularly or hypocellularly arranged with perivascular accentuation in a mucoid or fibrocollagenous background.The tumors contained numerous small-to medium-sized blood vessels,which were characteristically thin walled.Immunohistochemically,two cases of tumor cells were positive for vimentin,SMA,CD34(+)and FⅧ(+). Desmin and MSA were positive in one case:Cytokeratin,S-100,CD31 were negative in both. Conclusion:AMFB is a rare,benign soft tissue tumor that occurs in the genital tract of adult women.The origin remains unclear,but it is suggested that an origin from a perivascular pluripotent stem cell that is capable of myofibroblastoma differentiation.Angiomyofibroblastoma should be differentiated from other neoplasms of the vulva such as aggressive angiomyxoma, superficial angiomyxoma and cellular angiofibroma.

    Mucormycosis (MCM) is a life-threatening infection that carries high mortality rates despite recent advances in its diagnosis and treatment. The objective was to report 14 cases of mucormycosis infection and review the relevant literature. We retrospectively analyzed the demographic and clinical data of 14 consecutive patients that presented with MCM in a tertiary-care teaching hospital in northern Mexico. The mean age of the patients was 39.9 (range 5–65). Nine of the patients were male. Ten patients had diabetes mellitus as the underlying disease, and 6 patients had a hematological malignancy (acute leukemia). Of the diabetic patients, 3 had chronic renal failure and 4 presented with diabetic ketoacidosis. All patients had rhinocerebral involvement. In-hospital mortality was 50%. All patients received medical therapy with polyene antifungals and 11 patients underwent surgical therapy. Survivors were significantly younger and less likely to have diabetes than nonsurvivors, and had higher levels of serum albumin on admission. The clinical outcome of patients with MCM is poor. Uncontrolled diabetes and age are negative prognostic factors. PMID:25210515

    To evaluate the clinical presentations, radiological characteristics, and natural history of healthy adolescents presenting with idiopathic spontaneous pneumomediastinum. We retrospectively reviewed the simple radiographs of 14 consecutive patients (11 males) with spontaneous pneumomediastinum, who were examined over a period of 8 years, and analyzed their clinical history, radiographic findings including distribution, combined subcutaneous emphysema, mediastinal widening, pneumothorax, pleural effusion, and resolving period on follow up chest radiographs. We also obtained CT images of 7 patients for the assessment of additional information. The most common complaint at the time of presentation was chest pain and chest discomfort (8/14), followed by neck discomfort (6/14). The chest radiograph was of diagnostic value in alI cases. The main distribution of the pneumomediastinum was cervical (14/14), upper lung (13/14) and lower lung (6/14). Combined subcutaneous emphysema was observed in 6 patients. However, there were no cases of mediastinal widening, pneumothorax or pleural effusion. Complete resolution of the pneumomediastinum on the radiograph was observed after 10 days (mean 5.6), following purely conservative treatment. There was no additional information on the CT images, as compared with that on the radiographs. Idiopathic spontaneous pneumomediastinum is a benign entity that usually goes undiagnosed, but which responds very weIl to conservative treatment.

    Objective: To analyze the mechanism of diffuse axonal injury (DAI) and study the relationship between DAI and brain concussion, brain contusion, and primary brain stem injury.Methods: The clinical data and iconographic characteristics of 56 patients with DAI were analyzed retrospectively.Results: Traffic accidents were the main cause of DAI. Among the 56 cases, 34 were injured for at least twice, and 71.43% of the patients were complicated with contusion.Conclusions: It is considered that DAI is a common pattern of primary brain injury, which is often underestimated. And DAI includes cerebral concussion and primary brain injury, and is often complicated by cerebral cortex contusion. Therefore, it is very simple and practical to divide primary brain injuries into local and diffuse injuries.

    Full Text Available Fascioliasis is a worldwide but unevenly distributed zoonosis caused by the trematode Fasciola hepatica that infects do­mesti­cated herbivores. Fasciolosis also occurs accidentally in humans by ingestion of metacercaria-laden freshwater or water plants. Human infections are common in developing countries and are not rare in Europe. The clinical course has been con­ventionally described in two phases: an acute phase of hepatic parenchymal invasion of an immature worm larva (parenchy­mal phase and a stationary phase after residence in the bile duct and production of eggs (ductal phase. We report a 34 years old woman from Ilam, western Iran with hepatic disorder, RUQ pain, and jaundice. The diagnosis was made by sonography, CT scan and serologic studies. Serologic exam (ELISA was positive & CT findings were compatible with fascioliasis.

  19. [Clinical features of malignant hyperthermia crisis].

    Cornet, C; Moeller, R; Laxenaire, M C

    1989-01-01

    Malignant hyperthermia (MH) is a pharmacogenetic disorder. It is classically described as a hypermetabolic state triggered by halogenated anaesthetics and/or depolarizing muscle relaxants. In fact, since Denborough and Lovel's case, it has been shown that MH has a great number of clinical forms. The overwhelming picture of muscular hypercatabolism with fulminating hyperthermia and generalized rigidity is becoming rare. A better knowledge of the first symptoms explains in part the better prognosis: masseter spasm after suxamethonium, an increase in expired CO2 concentration, unexplained tachycardia, ventricular arrhythmias. The use of dantrolene reduced the mortality of MH. The different types of clinical manifestations are due to genetic differences, the concentration of the anaesthetic agent, and the length of time of exposure to the drug. The severity of the episode is linked to environmental factors such as stress, physical exercise, ambient temperature, concomitant use of other drugs. Masseter spasm after suxamethonium is specific for MH, but not pathognomonic. It occurs in 1% of cases in children when using halothane with suxamethonium. However, in those patients who displayed such a spasm, more than 50% had a positive contracture test. Masseter spasm is often associated with severe rhabdomyolysis in patients with muscle dystrophy, especially Duchenne's dystrophy. In the latter case, major cardiac problems may occur at the time of anaesthetic induction. Even if there are no other signs of MH, all patients who have had a masseter spasm must be considered as open to doubt, and should be further explored. MH is often difficult to diagnose in medium severity types.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Abstract Background Although several studies have been performed on risk factors and natural course of NASH, it seems that NASH tends to be more than a disease confined to strict boundaries. The objective of this study was to assess the clinical and paraclinical features and risk factors for non-alcoholic steatohepatitis (NASH patients in an Iranian population Methods Patients with histologically confirmed NASH who had elevated liver aminotransaminases, negative serologic markers of viral or autoimmune hepatitis and no findings in favor of metabolic liver disease were enrolled. A careful history was taken regarding alcohol intake. Results 53 patients consisting of 32 male and 21 female entered the study. The mean age was 37.8 ± 11.3 years. Twenty-six patients (55.3% were overweight, 15 (31.9% obese, 40 (75.5% dyslipidemic, and three patients (5.7% were diabetic. Liver biopsy showed mild steatosis in 35.7%, moderate steatosis in 53.6%, and severe forms in 10.7%. In 80.2% of patients, portal inflammation was present, and 9.4% had cirrhosis. The amount of increase in liver enzymes bore no relationship with fibrosis, portal inflammation, and degree of steatosis. Conclusions The patients in our study showed a male predominancy and were somewhat younger than other studies.

    Background In 2008 a nosocomial outbreak of five cases of viral hemorrhagic fever due to a novel arenavirus, Lujo virus, occurred in Johannesburg, South Africa. Lujo virus is only the second pathogenic arenavirus, after Lassa virus, to be recognized in Africa and the first in over 40 years. Because of the remote, resource-poor, and often politically unstable regions where Lassa fever and other viral hemorrhagic fevers typically occur, there have been few opportunities to undertake in-depth study of their clinical manifestations, transmission dynamics, pathogenesis, or response to treatment options typically available in industrialized countries. Methods and Findings We describe the clinical features of five cases of Lujo hemorrhagic fever and summarize their clinical management, as well as providing additional epidemiologic detail regarding the 2008 outbreak. Illness typically began with the abrupt onset of fever, malaise, headache, and myalgias followed successively by sore throat, chest pain, gastrointestinal symptoms, rash, minor hemorrhage, subconjunctival injection, and neck and facial swelling over the first week of illness. No major hemorrhage was noted. Neurological signs were sometimes seen in the late stages. Shock and multi-organ system failure, often with evidence of disseminated intravascular coagulopathy, ensued in the second week, with death in four of the five cases. Distinctive treatment components of the one surviving patient included rapid commencement of the antiviral drug ribavirin and administration of HMG-CoA reductase inhibitors (statins), N-acetylcysteine, and recombinant factor VIIa.

    Full Text Available Although the epidemiological data is generally obtained from the patients that applied for gender reassignment surgery, it is known that transsexualism is not seen as rarely as it was estimated in the past and should be evaluated in detail because of its psychological and social consequences. Etiology remains to be unclear and biological and psychosocial factors are thought to be responsible for its development. Gender identity stabilizes approximately in 3-4 ages and it is impossible to change it after these ages. For this reason the aim of treatment approaches is to improve the conformity of individuals to their identity and life, but not to change the gender identity. The World Professional Association for Transgender Health [WPATH] published a guideline including standards of care [SOC] and SOC provide clinical guidance in follow-up and treatment of transsexual individuals. There is a detailed code in civil law about gender reassignment but when this code implemented strictly, the use of it is very limited and it is clear that a new arrangement is needed in this issue.

  8. [Oral candidiasis: clinical features and control].

    Candidiasis is the most commonly encountered fungal infection, and oral candidiasis is often observed as a local opportunistic infection. Oral candidiasis is clinically divided into three types: acute forms, chronic forms, and Candida-associated lesions. Candida adhesion and multiplication are largely regulated by the local and systemic factors of the host. The local factors include impairment of the oral mucosal integrity, which is usually impaired by hyposalivation, anticancer drugs/radiation for head and neck cancers, denture wearing, a decrease in the oral bacterial population, and poor oral hygiene. Among Candida species, oral candidiasis is mostly caused by Candida albicans (C. albicans), C. glabrata, or C. tropicalis. Oral Candida induces a variety of symptoms, such as oral mucosal inflammation manifesting as an uncomfortable feeling, pain, erythema, erosion, taste abnormalities, and hyperplasia of the oral mucosa. Candida overgrowth in the oral cavity may disseminate to distant organs. Therefore, in order to avoid the sequelae of systemic candidiasis, oral candidiasis should be rapidly controlled. Oral candidiasis is usually treated by the local application of antifungal drugs. However, oral candidiasis occasionally escapes the control of such local treatment due to the development of multi-drug resistant Candida strains and species or due to the suppression of salivation or cellular immune activity. When drug-resistant strains are suspected as the pathogens and when the host is generally compromised, the oral administration of combinations of antifungal drugs, enhancement of cellular immune activity, and improvement of the nutritional condition are recommended.

    2005-09-01

    The term "functional food" refers to foods or ingredients of foods providing an additional physiological benefit beyond their basic nutritional needs. Health benefits are best obtained through a varied diet containing fruits, vegetables, grains, legumes and seeds. However, fortified foods and dietary supplements have been marketed and food industry have made functional food one of their current leading trends. Recently, the number of functional foods that have a potential benefit on health has hugely grown and scientific evidence is supporting the role of functional foods in prevention and treatment of several diseases. Cancer, diabetes, heart disease and hypertension are the most important diseases that can be treated or prevented by functional foods; other diseases are osteoporosis, abnormal bowel motility, and arthritis. It has been estimated that 80% of cancer in USA have a nutrition/diet component suggesting a great impact of functional food and foods components on incidence and treatment of cancer. Numerous factors complicate the evaluation of scientific evidence such as the complexity of food substance, effect on food, metabolic changes associated to dietary changes, the lack of biological markers of disease development. This paper reviews the scientific evidence supporting this area regarding only those foods and ingredients in which a clear experimental and clinical evidence exists for their chemopreventive and therapeutic effects.

    Full Text Available [u][/u] Narcolepsy is a chronic hypersomnia characterized by excessive daytime sleepiness (EDS and manifestations of disrupted rapid eye movement sleep stage (cataplexy, sleep paralysis, and hypnagogic/hypnopompic hallucinations. Mechanisms underlying narcolepsy are not fully understood. Experimental data indicate that the disease is caused by a loss of hypocretin neurons in the hypothalamus, likely due to an autoimmune process triggered by environmental factors in susceptible individuals. Most patients with narcolepsy and cataplexy have very low hypocretin-1 levels in the cerebrospinal fluid. An appropriate clinical history, polysomnogram, and multiple sleep latency test are necessary for diagnosis of the disease. Additionally, two biological markers, i.e., cerebrospinal fluid hypocretin-1 levels and expression of the DQB1*0602 gene, are used. The treatment of narcolepsy is aimed at the different symptoms that the patient manifests. Excessive daytime sleepiness is treated with psychostimulants (amphetamine-like, modafinil and armodafinil. Cataplexy is treated with sodium oxybate (GHB, tricyclic antidepressants, or selective serotonin and noradrenaline reuptake inhibitors. Sleep paralysis, hallucinations, and fragmented sleep may be treated with sodium oxybate. Patients with narcolepsy should follow proper sleep hygiene and avoid strong emotions.

    To evaluate types of gray matter heterotopias, associated brain anomalies, and its correlation with the patterns of seizure. We evaluated retrospectively 19 patients (male:female=10:9, mean age 21 years) with gray matter heterotopias on brain MRI. Using 1.0T superconducting MR unit, spin echo T1-, proton -density and T2-weighted images in axial, coronal and sagittal planes were obtained. Types of gray matter heterotopias were single subependymal in four patients, multiple subependymal in one, focal subcortical in eight, diffuse subcortical in two, mixed multiple subependymal and focal subcortical in four. Associated anomalies were seen in 11 patients: other neuronal migration anomalies in eight patients, corpus callosum agenesis in two, and combined holoprosencephaly and Dandy-Walker malformation in one. Fifteen patients had seizure. The patterns of seizure were not correlated with the types of heterotopias. In addition to subependymal, focal subcortical, and diffuse subcortical types, gray matter heterotopias included mixed variant of multiple subependymal and subcortical type. Schizencephaly was the most common form of accompanying anomalies, and patterns of seizure were not correlated with types of gray matter heterotopias, even though main clinical manifestation was seizure.

    Full Text Available Following a large outbreak of community-acquired psittacosis in 2002 in residents of the Blue Mountains, New South Wales, Australia, we reviewed new cases in this area over a 7-year period from 2003 to 2009. Using the 2010 criteria from the Centers for Disease Control National Notifiable Diseases Surveillance System, 85 patients with possible psittacosis were identified, of which 48 were identified as definite or probable infection. Clinical features of these cases are summarized. In addition to Chlamydia-specific serology, specimens, where available, underwent nucleic acid testing for chlamydial DNA using real-time PCR. Chlamydophila psittaci DNA was detected in samples from 23 patients. Four of 18 specimens were culture positive. This is the first description of endemic psittacosis, and is characterized in this location by community-acquired psittacosis resulting from inadvertent exposure to birds. The disease is likely to be under-diagnosed, and may often be mistaken for gastroenteritis or meningitis given the frequency of non-respiratory symptoms, particularly without a history of contact with birds. Clinical characteristics of endemic and outbreak-associated cases were similar. The nature of exposure, risk factors and reasons for the occurrence of outbreaks of psittacosis require further investigation.

    Full Text Available Parasomnias, as described in the recent second edition of the International Classification of Sleep Disorders, are “undesirable physical events or experiences” occurring during sleep transition, during arousal from sleep, or within the sleep period. These events encompass abnormal sleep related movements, behaviors, emotions, perceptions, dreaming, and autonomic nervous system functioning. Parasomnias are classified as: 1 disorders of arousal (from non-rapid eye movement, or NREM, sleep; 2 parasomnias usually associated with REM (rapid eye movement sleep; and 3 other parasomnias. This sleep disorders in childhood are common, and often more frequent than in adults. Clinicians should be aware that many pediatric parasomnias have benign and self-limited nature. Most of the parasomnias may not persist into late childhood or adolescence. Parasomnias in adults often differ in type from childhood parasomnias and may portend significant psychiatric disturbances or neurodegenerative disorders. A reliable diagnosis can often be made from a detailed history from the patient and, if possible, the parents or bed partner. Detailed overnight investigations of parasomnias are usually not required. The non-REM parasomnias are more common in community although REM parasomnias are more likely to be seen in general neurological practice. Sleep related eating disorder, sleep related dissociative disorders and sleep related sexual behavior and sleep related violence are novel and rarely reported sleep disorders. REM sleep behavior disorder is common and should be sought in all neurodegenerative diseases. They are included among clinical disorders due to the resulting injuries, and adverse health and psychosocial effects, which may affect the bed partner as well as the patient. Finally, parasomnias are common disturbances of sleep that may significantly affect the patient’s quality of life and that of the bed partner. Therefore, appropriate diagnostic and

    alter the pedophile’s sexual orientation toward children, much of the focus of pedophilic treatment is on stopping further offenses against children. The combination of pharmacologic and behavioral treatment coupled with close legal supervision appears to help reduce the risk of repeated offense. Currently chemical castration; testosterone suppression by antiandrogenic therapy is a popular treatment option. Effective prevention is most effective means to manage the sexual abusement of children. For primary prevention and treatment, it is necessary to know the characteristics of pedophilia and understand the factors that lead to the development of the pedophilic tendencies.

    Objective To investigate the incidence, imaging and clinical characteristics in elderly patients with coronary artery ectasia (CAE). Methods A retrospective analysis was conducted on patients with CAE who underwent coronary angiography between January 2006 and December 2012. According to age, the enrolled patients were divided into two groups (elderly group, age≥ 65 years; non-elderly group, age < 65 years). The clinical feature, imaging characteristics and the 5-year survival rate of the two groups were compared.Results The preva-lence of CAE in elderly patients was 0.33%. Patients in elderly group were found to have significantly higher proportion of female (30.1%vs. 10.1%,P< 0.001), three-vessel disease (60.5%vs. 45.2%,P = 0.003) and localized ectasia (55.0%vs. 40.2%,P = 0.003). In addition, body mass index (20.90 ± 2.71 kg/m2vs. 22.31 ± 2.98 kg/m2,P < 0.001) and percentage of current smokers (45.0%vs. 64.6%,P < 0.001) were significantly lower in elderly group. Cumulative survival curves demonstrated reduced 5-year cumulative survival at the follow-up in the elderly group compared with the non-elderly group (88.0%vs. 96.0%,P = 0.002). But the 5-year event free survival rate failed to show a significant difference between the two groups (31.0%vs. 35.0%,P= 0.311).ConclusionThe prevalence of CAE in elderly patients was 0.33%, which was about 1/3 of the entire numbers of CAE patients. There were significant differences between the elderly and the non-elderly patients with CAE in terms of coronary artery disease risk factors and coronary artery ectatic characteristics. CAE might be asso-ciated with increased mortality risk in the elderly.

    Full Text Available Children regularly and voluntarily go to school in order to fulfill the expectations of society from them to continue their education or schooling. School continuation has been made compulsory by laws. Nonetheless, contrary to popular belief, for some children it is distressing to go to school. These children have difficulty continuing school and/or refuse to go to school. Today school refusal is defined as a child’s inability to continue school for reasons, such as anxiety and depression. The prevalence of school refusal has been reported to be approximately 1% in school-age children and 5% in child psychiatry samples. The prevalence of school refusal is similar among boys and girls. School refusal can occur at any time throughout the child’s academic life and at all socio-economic levels. School refusal is considered a symptom rather than a clinical diagnosis and can manifest itself as a sign of many psychiatric disorders, with anxiety disorders predominant. Separation anxiety disorder, generalized anxiety disorder, social phobia, specific phobia, and adjustment disorder with anxiety symptoms are the most common disorders co-occurring with school refusal. While separation anxiety disorder is associated with school refusal in younger children, other anxiety disorders, especially phobias, are associated with school refusal in adolescents. Children who have parents with psychiatric disorders have a higher incidence of school refusal, and psychiatric disorders are more frequently seen in adult relatives of children with school refusal, which supports a significant role of genetic and environmental factors in th etiology of school refusal. School refusal is a emergency state for child mental health. As it leads to detrimental effects in the short term and the long term, it should be regarded as a serious problem. The long-lasting follow-up studies of school refusing children have revealed that these children have a higher incidence of

    2015-02-01

    Modern healthcare is getting reshaped by growing Electronic Medical Records (EMR). Recently, these records have been shown of great value towards building clinical prediction models. In EMR data, patients' diseases and hospital interventions are captured through a set of diagnoses and procedures codes. These codes are usually represented in a tree form (e.g. ICD-10 tree) and the codes within a tree branch may be highly correlated. These codes can be used as features to build a prediction model and an appropriate feature selection can inform a clinician about important risk factors for a disease. Traditional feature selection methods (e.g. Information Gain, T-test, etc.) consider each variable independently and usually end up having a long feature list. Recently, Lasso and related l1-penalty based feature selection methods have become popular due to their joint feature selection property. However, Lasso is known to have problems of selecting one feature of many correlated features randomly. This hinders the clinicians to arrive at a stable feature set, which is crucial for clinical decision making process. In this paper, we solve this problem by using a recently proposed Tree-Lasso model. Since, the stability behavior of Tree-Lasso is not well understood, we study the stability behavior of Tree-Lasso and compare it with other feature selection methods. Using a synthetic and two real-world datasets (Cancer and Acute Myocardial Infarction), we show that Tree-Lasso based feature selection is significantly more stable than Lasso and comparable to other methods e.g. Information Gain, ReliefF and T-test. We further show that, using different types of classifiers such as logistic regression, naive Bayes, support vector machines, decision trees and Random Forest, the classification performance of Tree-Lasso is comparable to Lasso and better than other methods. Our result has implications in identifying stable risk factors for many healthcare problems and therefore can

    Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas can exhibit a wide spectrum of macroscopic and microscopic appearances. This not only causes occasional difficulties for the reporting pathologist in distinguishing these tumours from other lesions, but is also relevant clinically. As evidence accumulates, it becomes clear that multiple macroscopic and histological features of these neoplasms are relevant to the risk for malignant transformation and, consequently, of prime importance for clinical patient management. The need for detailed reporting is therefore increasing. This review discusses the panoply of gross and microscopic features of IPMN as well as the recommendations from recent consensus meetings regarding the pathology reporting on this tumour entity.

    Full Text Available Background: Chronic actinic dermatitis (CAD, one of the immune mediated photo-dermatoses, comprises a spectrum of conditions including persistent light reactivity, photosensitive eczema and actinic reticuloid. Diagnostic criteria were laid down about 20 years back, but clinical features are the mainstay in diagnosis. In addition to extreme sensitivity to UVB, UVA and/or visible light, about three quarters of patients exhibit contact sensitivity to several allergens, which may contribute to the etiopathogenesis of CAD. This study was undertaken to examine the clinical features of CAD in India and to evaluate the relevance of patch testing and photo-aggravation testing in the diagnosis of CAD. Methods: The clinical data of nine patients with CAD were analyzed. Histopathology, patch testing and photo-aggravation testing were also performed. Results: All the patients were males. The average age of onset was 57 years. The first episode was usually noticed in the beginning of summer. Later the disease gradually tended to be perennial, without any seasonal variations. The areas affected were mainly the photo-exposed areas in all patients, and the back in three patients. Erythroderma was the presenting feature in two patients. The palms and soles were involved in five patients. Patch testing was positive in seven of nine patients. Conclusions: The diagnosis of CAD mainly depended upon the history and clinical features. The incidence of erythroderma and palmoplantar eczema was high in our series. Occupation seems to play a role in the etiopathogenesis of CAD.

    Steatocystoma multiplex (SM) shares many clinical features and may show overlapping histopathological features with eruptive vellus hair cyst (EVHC). Clinical data and pathologic features of 64 patients with SM were evaluated in detail. Most of the cases were sporadic, with an average onset age of 26 years and distribution on the arms, chest, axillae, and neck. All cases exhibited eosinophilic cuticle and lack of granular layer, and 17-42% displayed vellus hair, hair follicles, keratin, and smooth muscle components within the cavity, in the wall, or adjacent to it. The results of this study add further evidence to the hypothesis that SM is a hamartomatous condition and that SM and EVHC are variants of one disorder which originates in the pilosebaceous duct.

    Clinical laboratory tests play an integral role in medical decision-making and as such must be reliable and accurate. Unfortunately, no laboratory tests or devices are foolproof and errors can occur at pre-analytical, analytical and post-analytical phases of testing. Evaluating possible conditions that could lead to errors and outlining the necessary steps to detect and prevent errors before they cause patient harm is therefore an important part of laboratory testing. This can be achieved through the practice of risk management. EP23-A is a new guideline from the CLSI that introduces risk management principles to the clinical laboratory. This guideline borrows concepts from the manufacturing industry and encourages laboratories to develop risk management plans that address the specific risks inherent to each lab. Once the risks have been identified, the laboratory must implement control processes and continuously monitor and modify them to make certain that risk is maintained at a clinically acceptable level. This review summarizes the principles of risk management in the clinical laboratory and describes various quality control activities employed by the laboratory to achieve the goal of reporting valid, accurate and reliable test results.

    Morvan's Fibrillary Chorea (MFC) is a rare autoimmune disorder causally associated with auto-antibodies directed at the voltage-gated potassium channel (VGKC-Abs). It classically presents with sleep disturbances, neuromyotonia and dysautonomia. We aimed to systematically characterise the features of MFC by describing a patient and reviewing published literature. Case notes of 27 patients with MFC (one from our clinic and 26 from the literature) were reviewed and clinical data were extracted and analysed. We found that MFC mainly affects men (96%) and runs a subacute course over months. Neoplasia (56%), VGKC-Abs positivity (79%) and autoimmunity (41%) are frequent associations. Myokymia, insomnia and hyperhidrosis were almost universally described. Other autonomic features were present in 63% with the most common being cardiovascular and bowel disturbances. Clinical, radiological or electroencephalographical features of limbic encephalitis were present in 19% of patients. Outcome was fair with an overall recovery rate of 78%. All patients with malignancies underwent surgery. Immunotherapies including corticosteroids, intravenous immunoglobulins and plasma exchange were instituted in 22 patients and 19 (86%) responded. Of all symptomatic treatments tried, carbamazepine, phenytoin, sodium valproate, levetiracetam and niaprazine were found to be effective. The broad clinical spectrum of VGKC-Abs diseases can make early recognition of MFC difficult. Myokymia, insomnia and hyperhidrosis are invariably present. There may be abnormalities on cerebrospinal fluid testing and VGKC-Abs can occasionally be absent. Early initiation of immunotherapies and malignancy screening are important to prevent adverse outcomes in a condition that generally responds favourably to treatment.

    A dermatoscope is an important tool in a dermatologist's armamentarium as it can eliminate the need for a biopsy in a wide array of conditions. Porokeratosis was described by Mibelli and Respighi in 1893, as a disorder of keratinization which on the basis of distribution patterns was described as five clinical variants that portrayed a coronoid lamella on histopathology. We describe a case of asymptomatic, long-standing palmar and plantar pits, which on dermatoscopy showed features suggestive of porokeratosis, which was later reconfirmed by histopathologic sections. This report depicts diagnostic features of porokeratosis and obviates the need for invasive procedures for its diagnosis. PMID:27559506

    Full Text Available The aim of the study was to examine the structure of psychopathology and clinical features of depressive disorders in patients with brain oncopathology. Polymorphic mental disorders of various clinical content and severity in most cases not only are comorbid to oncological pathology of the brain, but most often are the first clinical signs of early tumors. The study was conducted using the following methods: clinical psychiatric, questionnaire Simptom Check List- 90 -Revised-SCL- 90 -R, Luscher test and mathematical processing methods. Sample included 175 patients with brain tumors with non-psychotic level of mental disorders. The peculiarities of mental disorders and psychopathological structure of nonpsychotic depressive disorders have been a clinical option of cancer debut in patients with brain tumors. We found that nonpsychotic depression is characterized by polymorphism and syndromal incompletion; this causes ambiguity of diagnoses interpretation on stages of diagnostic period. Features of depressive symptoms depending on the signs of malignancy / nonmalignancy of brain tumor were defined.

    Full Text Available BACKGROUND: Infants account for a small proportion of the overall dengue case burden in endemic countries but can be clinically more difficult to manage. The clinical and laboratory features in infants with dengue have not been extensively characterised. METHODOLOGY/PRINCIPAL FINDINGS: This prospective, cross-sectional descriptive study of infants hospitalized with dengue was conducted in Vietnam from November 2004 to December 2007. More than two-thirds of 303 infants enrolled on clinical suspicion of dengue had a serologically confirmed dengue virus (DENV infection. Almost all were primary dengue infections and 80% of the infants developed DHF/DSS. At the time of presentation and during hospitalization, the clinical signs and symptoms in infants with dengue were difficult to distinguish from those with other febrile illnesses, suggesting that in infants early laboratory confirmation could assist appropriate management. Detection of plasma NS1 antigen was found to be a sensitive marker of acute dengue in infants with primary infection, especially in the first few days of illness. CONCLUSIONS/SIGNIFICANCE: Collectively, these results provide a systematic description of the clinical features of dengue in infants and highlight the value of NS1 detection for diagnosis.

    Diagnostic uncertainty when a patient presents with melasma-like Undings can lead to suboptimal treatment and inaccurate prognostic expectations. In this study, the authors present a unique clinical feature of melasma that they term the "Fitzpatrick macule" and test its Utility in establishing diagnostic certainty. The "Fitzpatrick macule" is a confetti-like macule of regularly pigmented skin located within a larger patch of melasma hyperpigmentation. To test its diagnostic Utility, the authors compared clinical photography of known cases of melasma with common mimickers, such as poikiloderma of Civatte and solar lentiginosis, and determined the positivity rate of the Fitzpatrick macule in each scenario. Their results show that 89.1 percent of clinical photographs of melasma were positive for the presence of Fitzpatrick macules compared to 1.1 percent that were negative. In contrast, 37.5 and 56.3 percent of clinical photographs of poikiloderma of Civatte were positive and negative for Fitzpatrick macules, respectively. Solar lentiginosis showed a 5.6 percent positivity and a 77.8 percent negativity for Fitzpatrick macules. The sensitivity and specificity of Fitzpatrick macules for melasma was 99 and 83 percent, respectively. In summary, the authors report a highly sensitive and specific clinical feature of melasma. In cases of diagnostic uncertainty, the presence of Fitzpatrick macules may aid in establishing a diagnosis of melasma.

    Full Text Available BACKGROUND: The emergence of dengue throughout the tropical world is affecting an increasing proportion of adult cases. The clinical features of dengue in different age groups have not been well examined, especially in the context of early clinical diagnosis. METHODOLOGY/PRINCIPAL FINDINGS: We structured a prospective study of adults (≥ 18 years of age presenting with acute febrile illness within 72 hours from illness onset upon informed consent. Patients were followed up over a 3-4 week period to determine the clinical outcome. A total of 2,129 adults were enrolled in the study, of which 250 (11.7% had dengue. Differences in the rates of dengue-associated symptoms resulted in high sensitivities when the WHO 1997 or 2009 classification schemes for probable dengue fever were applied to the cohort. However, when the cases were stratified into age groups, fewer older adults reported symptoms such as myalgia, arthralgia, retro-orbital pain and mucosal bleeding, resulting in reduced sensitivity of the WHO classification schemes. On the other hand, the risks of severe dengue and hospitalization were not diminished in older adults, indicating that this group of patients can benefit from early diagnosis, especially when an antiviral drug becomes available. Our data also suggests that older adults who present with fever and leukopenia should be tested for dengue, even in the absence of other symptoms. CONCLUSION: Early clinical diagnosis based on previously defined symptoms that are associated with dengue, even when used in the schematics of both the WHO 1997 and 2009 classifications, is difficult in older adults.

    Full Text Available Catatonia is not a usual clinical presentation of subacute sclerosing panencephalitis (SSPE, especially in the initial stages of illness. However, there is only one reported case of SSPE presenting as catatonia among children. In this report, however, there were SSPE-specific changes on EEG and the catatonia failed to respond to lorazepam. We describe a case of SSPE in a child presenting as catatonia that presented with clinical features of catatonia and did not have typical EEG findings when assessed at first contact. He responded to lorazepam and EEG changes emerged during the course of follow-up.

    Full Text Available Hereditary spastic paraplegia (HSP is a group of genetically-determined disorders characterized by progressive spasticity and weakness of lower limbs. An apparently sporadic case of adult-onset spastic paraplegia is a frequent clinical problem and a significant proportion of cases are likely to be of genetic origin. HSP is clinically divided into pure and complicated forms. The later present with a wide range of additional neurological and systemic features. To date, there are up to 60 genetic subtypes described. All modes of monogenic inheritance have been described: autosomal dominant, autosomal recessive, X-linked and mitochondrial traits. Recent advances point to abnormal axonal transport as a key mechanism leading to the degeneration of the long motor neuron axons in the central nervous system in HSP. In this review we aim to address recent advances in the field, placing emphasis on key diagnostic features that will help practicing neurologists to identify and manage these conditions.

    Research on neuro signals is challenging and significative in modern natural science. By clinical experiment, signals from three main nerves (median nerve, radial nerve and ulnar nerve) are successfully detected and recorded without any infection. Further analysis on their features under different movements, their mechanics and correlations in dominating actions are also performed. The original discovery and first-hand materials make it possible for developing practical neuro-prosthesis.

    Interstitial lung disease (ILD) is the most common extra-articular manifestations of rheumatoid arthritis (RA) in the lung. This study aimed to identify clinical features of RA-associated ILD (RA-ILD). Patients with RA were retrospectively enrolled and sub-classified as RA-ILD or RA without ILD based on high-resolution computed tomography imaging. Pulmonary function testing parameters and levels of RA-related biomarkers, tumour markers, and acute-phase proteins were compared between the two groups. Logistic regression model was used to assess the strength of association between RA-ILD and clinical features of interest. Receiver operating characteristic analysis was performed to assess potential predictive value of clinical features for detecting RA-ILD. Comparison analysis indicated that the percentage of predicted value of total lung capacity, inspiratory capacity, and diffusion capacity of the lung for carbon monoxide (DLCO) were reduced in patients with RA-ILD. Tumour markers CA15-3 and CA125 were increased in patients with RA-ILD. Logistic regression analysis revealed that decreased DLCO was related to the increased likelihood of RA-ILD (OR = 0.94, 95%CI = [0.91, 0.98]). The cut-off point at 52.95 percent of predicted value could sensitively discriminate RA patients with or without ILD. Our study suggested that DLCO value could be a useful tool for detecting ILD in patients with RA.

Material and Methods. 130 RA pts aged 16 to 80 years (mean age 52,5 years, 105 female and 25 male were examined. 55 pts had disease duration up to 1 year, 34 - between 1 and 3 years and 41 - more than 3 years. Standard clinical, laboratory and radiological examination was performed in all pts. In 43 pts with earlv RA T and В cell receptors were studied with monoclonal antibodies against CD3, CD72, CD4, CD8, CDI6. Results. The most frequent initial symptoms preceding characteristic RA picture were arthralgia (39,2%, fever (34,6% and body weight loss (24,6%. Mono- or oligoarticuiar onset with subsequent quick transformation into polyarthritis within one year revealed in 61,5% of pts was the usual feature of early RA. The most frequent false diagnoses in early RA were osteoarthritis (in 25,1%, reactive arthritis (in 24,9% and gout (in 4,6%. Male pts had longer morning stiffness, higher levels of C-reactive protein, more pronounced functional disability, T and В cell immunity activation than female. Conclusion. Understanding of essential clinical and immunologic features of early RA will allow to diagnose the disease in time.

    The purpose of this study was to analyse MR imaging features and lesion patterns as defined by compromised vascular territories, correlating them to different clinical syndromes and aetiological aspects. In a 19.8-year period, clinical records and magnetic resonance imaging (MRI) features of 55 consecutive patients suffering from spinal cord ischemia were evaluated. Aetiologies of infarcts were arteriosclerosis of the aorta and vertebral arteries (23.6 %), aortic surgery or interventional aneurysm repair (11 %) and aortic and vertebral artery dissection (11 %), and in 23.6 %, aetiology remained unclear. Infarcts occurred in 38.2 % at the cervical and thoracic level, respectively, and 49 % of patients suffered from centromedullar syndrome caused by anterior spinal artery ischemia. MRI disclosed hyperintense pencil-like lesion pattern on T2WI in 98.2 %, cord swelling in 40 %, enhancement on post-contrast T1WI in 42.9 % and always hyperintense signal on diffusion-weighted imaging (DWI) when acquired. The most common clinical feature in spinal cord ischemia is a centromedullar syndrome, and in contrast to anterior spinal artery ischemia, infarcts in the posterior spinal artery territory are rare. The exclusively cervical location of the spinal sulcal artery syndrome seems to be a likely consequence of anterior spinal artery duplication which is observed preferentially here. (orig.)

    Full Text Available To improve our understanding of sex differences in the clinical characteristics of Parkinson's Disease, we sought to examine differences in the clinical features and disease severity of men and women with early treated Parkinson's Disease (PD enrolled in a large-scale clinical trial.Analysis was performed of baseline data from the National Institutes of Health Exploratory Trials in Parkinson's Disease (NET-PD Long-term Study-1, a randomized, multi-center, double-blind, placebo-controlled study of 10 grams of oral creatine/day in individuals with early, treated PD. We compared mean age at symptom onset, age at PD diagnosis, and age at randomization between men and women using t-test statistics. Sex differences in clinical features were evaluated, including: symptoms at diagnosis (motor and symptoms at randomization (motor, non-motor, and daily functioning.1,741 participants were enrolled (62.5% male. No differences were detected in mean age at PD onset, age at PD diagnosis, age at randomization, motor symptoms, or daily functioning between men and women. Differences in non-motor symptoms were observed, with women demonstrating better performance compared to men on SCOPA-COG (Z = 5.064, p<0.0001 and Symbol Digit Modality measures (Z = 5.221, p<0.0001.Overall, men and women did not demonstrate differences in clinical motor features early in the course of PD. However, the differences observed in non-motor cognitive symptoms suggests further assessment of the influence of sex on non-motor symptoms in later stages of PD is warranted.

    Full Text Available PURPOSE: To investigate the clinical features, clinical course of granuloma, serologic findings, treatment outcome, and probable infection sources in adult patients with ocular toxocariasis (OT. METHODS: In this retrospective cohort study, we examined 101 adult patients diagnosed clinically and serologically with OT. Serial fundus photographs and spectral domain optical coherence tomography images of all the patients were reviewed. A clinic-based case-control study on pet ownership, occupation, and raw meat ingestion history was performed to investigate the possible infection sources. RESULTS: Among the patients diagnosed clinically and serologically with OT, 69.6% showed elevated immunoglobulin E (IgE levels. Granuloma in OT involved all retinal layers and several vitreoretinal comorbidities were noted depending on the location of granuloma: posterior pole granuloma was associated with epiretinal membrane and retinal nerve fiber layer defects, whereas peripheral granuloma was associated with vitreous opacity. Intraocular migration of granuloma was observed in 15 of 93 patients (16.1%. Treatment with albendazole (400 mg twice a day for 2 weeks and corticosteroids (oral prednisolone; 0.5-1 mg/kg/day resulted in comparable outcomes to patients on corticosteroid monotherapy; however, the 6-month recurrence rate in patients treated with combined therapy (17.4% was significantly lower than that in patients treated with corticosteroid monotherapy (54.5%, P=0.045. Ingestion of raw cow liver (80.8% or meat (71.2% was significantly more common in OT patients than healthy controls. CONCLUSIONS: Our study discusses the diagnosis, treatment, and prevention strategies for OT. Evaluation of total IgE, in addition to anti-toxocara antibody, can assist in the serologic diagnosis of OT. Combined albendazole and corticosteroid therapy may reduce intraocular inflammation and recurrence. Migrating feature of granuloma is clinically important and may further suggest

    AIM: To study the dynamic computed tomography (CT) features of hepatic angiomyolipoma (AML) in patients with or without tuberous sclerosis complex (TSC). METHODS: The clinical information, CT findings and histopathological results of hepatic AML were analyzed retrospectively in 10 patients. RESULTS: Hepatic AML was prone to occur in female patients (7/10), and most of the patients (8/10) had no specific symptoms. All tumors presented as welldefined, unenveloped nodules in the liver. Six patients with sporadic hepatic AML had a solitary hepatic nodule with a definite fat component. Non-fat components of the hepatic lesions were enhanced earlier and persistently. Prominent central vessels were noted in the portal venous phase in three patients. In four patients with hepatic AML and TSC, most of the nodules were within the peripheral liver. Seven fatdeficient nodules were found with earlier contrast enhancement and rapid contrast material washout in two patients. Lymphangioleiomyomatosis was found in one patient.CONCLUSION: Imaging features of hepatic AML are characteristic. Correct diagnosis preoperatively can be made in combination with clinical features.

    Full Text Available and lsquo;Pilonidal sinus' disease, which is most commonly seen in reproductive populations, such as young adults - mostly in males who are in their twenties - is actually a controversial disease in that there is no consensus on its many facets. It is sometimes seen as an infected abscess draining from an opening or a lesion extending to the perineum. It may also present as a draining fistula opening to skin. In terms of etiological factors, various theories (main theories being congenital and acquired have been established since it was first described, no universal understanding achieved. A long and significant post-operative care period with different lengths of recovery depending on the type of operation are quite prevalent with regards to recurrence and complication status. In order to prevent recurrence and improve the quality of life, etiological and predisposing factors as well as clinical features of sacrococcygeal pilonidal disease should be well known, a detailed differential diagnosis should be made, and a suitable and timely intervention should be performed. It was aimed here to explain the etiological factors, pathogenesis and clinical features of the disease that may present with various clinical symptoms. [Arch Clin Exp Surg 2016; 5(4.000: 228-232

    2013-04-10

    This review focuses on summarizing 2 pivotal articles in the clinical and pathophysiologic understanding of hemicrania continua (HC). The first article, a functional imaging project, identifies both the dorsal rostral pons (a region associated with the generation of migraines) and the posterior hypothalamus (a region associated with the generation of cluster and short-lasting unilateral neuralgiform headache with conjunctival injection and tearing [SUNCT]) as active during HC. The second article is a summary of the clinical features seen in a prospective cohort of HC patients that carry significant diagnostic implications. In particular, they identify a wider range of autonomic signs than what is currently included in the International Headache Society criteria (including an absence of autonomic signs in a small percentage of patients), a high frequency of migrainous features, and the presence of aggravation and/or restlessness during attacks. Wide variations in exacerbation length, frequency, pain description, and pain location (including side-switching pain) are also noted. Thus, a case is made for widening and modifying the clinical diagnostic criteria used to identify patients with HC.

    Dacryocystitis-related orbital cellulitis is a relatively rare condition, and large case series of this clinical entity have been reported. This study was undertaken to identify a larger cohort of patients with this ailment, with the intent of defining its clinical and microbiologic features. Case logs from four institutions were reviewed to identify patients that suffered from dacryocystitis-related orbital cellulitis. A retrospective chart review was then performed to identify clinical features, management strategies, microbiologic features, and outcomes. A dedicated statistical software package was utilized to identify correlations between these variables. 13 patients (7 females, 6 males; mean age = 57.2 years, range = 7-89 years) were identified. One patient carried a diagnosis of immunosuppressive disease. All patients underwent emergent surgical drainage and received intravenous antibiotics. Primary acquired nasolacrimal duct obstruction was found to be the underlying etiology in nine cases (69.2%), whereas four patients suffered from specific causes of their obstructions. An average of 1.07 organisms/patient (standard deviation = 0.49 organisms/patient) were recovered from microbiologic cultures, and Gram-positive bacteria represented the majority of cultured organisms. All patients experienced either stable or improved vision upon discharge. The relationships between a specific etiology and the possibility of vision loss or the number of organisms cultured, between the number of organisms cultured and vision loss, and immunosuppression and vision loss or the number of organisms cultured were all not statistically significant (p > 0.05). Dacryocystitis-related orbital cellulitis most commonly occurs in adult patients who do not carry immunosuppressive diagnoses and suffer from primary obstructions. Multiple microbiologic species may cause this problem, although Gram-positive organisms are most common. With appropriate management, stable or improved vision

    Full Text Available BACKGROUND: A single centre study was planned to asses the incidence and clinical feature of snake bite cellulitis in order to find out the nature and burden of the disease. OBJECTIVES: To assess incidence and clinical features of snake bite cellulitis. METHODOLOGY: This present one year prospective study was conducted in the Department of Surgery, Karnataka Institute of Medical Sciences, Hubli. Out of 520 total cases of snake bites 66 patients with cellulitis changes were studied. STATISTICAL ANALYSIS: The data obtained was coded and entered in Microsoft Excel Spreadsheet. The categorical data was expressed as rates, ratios and percentages. RESULTS: Out of 520 total snake bite cases, 66 patients developed signs of cellulitis. In patients with cellulitis 49(74.24% were males and 17(25.75% were females. In patients with cellulitis, most were aged between 31 to 45 years (36.36% and 19 to 30 years (34.84.The mean age of the study population was 32.43 ± 13.75 years. Majority of the patients (74.24% had snake bite on lower limbs. Most common symptom complex noted was pain + swelling in 30(39.39% of the patients followed by pain in 9(13.6%, swelling in 6(9%, pain+swelling+fever in 4(6%, pain + discolouration in 2(3% and pain + fever in 1(1.5% of the patients. CONCLUSIONS: The present study shows high incidence of cellulitis in patients with snake bite and most common clinical feature is cellulitis is pain + swelling. So in any case of snake of snake bite we should take the proper precautionary measures to prevent cellulitis. If cellulitis has already formed, then it should be treated without delay in order to prevent limb loss, compartment syndrome, other morbidities and even death.

    Introduction Data specific to late-life bipolar disorder (BD) are limited. Current research is sparse and present guidelines are not adapted to this group of patients. Objectives We present a literature review on clinical characteristics, comorbidities, and cognitive impairment in patients with late-life BD. This review discusses common comorbidities that affect BD elders and how aging might affect cognition and treatment. Methods Eligible studies were identified in MedLine by the Medical Subject Headings terms “bipolar disorder” and “aged”. We only included original research reports published in English between 2012 and 2015. Results From 414 articles extracted, 16 studies were included in the review. Cardiovascular and respiratory conditions, type II diabetes, and endocrinological abnormalities were observed as highly prevalent. BD is associated with a high suicide risk. Bipolar elderly had an increased risk of dementia and performed worse on cognitive screening tests compared to age-matched controls across different levels of cognition. Despite high rates of medical comorbidity among bipolar elderly, a systematic under-recognition and undertreatment of cardiovascular disease have been suggested. Conclusion There was a high burden of physical comorbidities and cognitive impairment in late-life BD. Bipolar elderly might be under-recorded and undertreated in primary medical care, indicating that this group needs an adapted clinical assessment and specific clinical guidelines need to be established.

    In order to know the epidemiological and clinical features of trichinosis, the data of 208 patients with trichinosis from 1992 to 1994 were analysed. The results showed that these patients came from 11 districts, and acquired the infection mainly by tasting the raw pork filling for dumplings or ingesting instant-boiled pork or mutton. The incidence of trichinosis is high in winter. Young and middle-aged workers and cadres constituted the majority of the patients and the infection was more common in the males than in females. The main clinical manifestations of trichinosis were prolonged fever, general myalgia, muscle weekness and eosinophilia. Most of the patients had no gastrointestinal symptoms and skin eruption. Eyelid edema was only seen in the early stage. Serological tests were significant value in the diagnosis of trichinosis. The key measures to prevent trichinosis were that meat inspection should be strictly carried out and bad eating habit changed.

    Purpose The aim of this study was to investigate the clinical features and extraintestinal manifestations (EIMs) of Crohn disease (CD) in Korean pediatric patients. Methods The medical records of 73 children diagnosed with CD were retrospectively reviewed. Data regarding baseline demographic and clinical characteristics, including CD phenotype at diagnosis based on the Montreal classification, and clinical features and course of EIMs were investigated. Results Fifty-two (71.2%) of the patients were males. The mean age of the patients was 12.5 years. The mean follow-up period was 3.4 years. The disease location was ileal in 3 (4.1%) of the patients, colonic in 13 (17.8%), ileocolonic in 56 (76.7%). The clinical behavior was inflammatory in 62 (84.9%) of the patients, stricturing in 8 (11.0%), and penetrating in 3 (4.1%). Perianal abscesses or fistulas were found in 37 (50.7%) of the patients. EIMs observed during the study period were anal skin tag in 25 patients (34.2%), hypertransaminasemia in 20 (27.4%), peripheral arthritis in 2 (2.7%), erythema nodosum in 2 (2.7%), vulvitis in 1 (1.4%), uveitis in 1 (1.4%), and pulmonary thromboembolism in 1 (1.4%). Conclusion Perianal diseases and manifestations were present in more than half of Korean pediatric CD patients at diagnosis. Inspection of the anus should be mandatory in Korean children with suspicious CD, as perianal fistulas, abscesses, and anal skin tags may be the first clue to the diagnosis of CD. PMID:28090468

    Objective To discuss thepathogenesis, etiology, clinical manifestations, diagnosis, treatment and prognosis of right-sided infective endocarditis (RIE) . Methods To investigate retrospectively the clinical data of patients with RIE admitted in our hospital from Jan 1985 to Dec 2000.Results There were 17 cases of RIE (12 male, 5female, mean age 22 years), among which 7 with congenital heart disease, 1 with pacemaker implantation and 9 with a history of intravenous drug abuse but without underlying heart disease. Fever and multiple pulmonary emboli were the major clinical manifestations. Blood cultures were positive in 8 cases with Staphylococcus aureus as the predominant microorganism. Echocardiography detected right heart vegetations in all cases, with tricuspid valve as the structure most frequently affected. Most patients were successfully treated with antimicrobials. The outcome was favourable, with a mortality of 11.8 % . Conclusions The clinical features of RIE are different from that of left-sided infective endocarditis (LIE) . Echocardiography plays an important role in the diagnosis of RIE.

    2015-11-01

    Synopsis Gluteal tendinopathy is now believed to be the primary local source of lateral hip pain, or greater trochanteric pain syndrome, previously referred to as trochanteric bursitis. This condition is prevalent, particularly among postmenopausal women, and has a considerable negative influence on quality of life. Improved prognosis and outcomes in the future for those with gluteal tendinopathy will be underpinned by advances in diagnostic testing, a clearer understanding of risk factors and comorbidities, and evidence-based management programs. High-quality studies that meet these requirements are still lacking. This clinical commentary provides direction to assist the clinician with assessment and management of the patient with gluteal tendinopathy, based on currently limited available evidence on this condition and the wider tendon literature and on the combined clinical experience of the authors.

    Crucial to the management of staphylococcal bacteremia is an accurate evaluation of associated endocarditis, which has both therapeutic and prognostic implications. Because the clinical presentation of endocarditis can be nonspecific, the judicious use of echocardiography is important in distinguishing patients at high risk of developing endocarditis. In the presence of high-risk clinical features, an early transesophageal echocardiogram is warranted without prior transthoracic echocardiography. The purpose of this study was to investigate the clinical risk factors for staphylococcal infective endocarditis that might warrant earlier transesophageal echocardiography and to describe the incidence of endocarditis in cases of methicillin-resistant and methicillin-sensitive Staphylococcus aureus bacteremia. A retrospective case-control study was conducted by means of chart review of 91 patients consecutively admitted to a community hospital from January 2009 through January 2013. Clinical risk factors of patients with staphylococcal bacteremia were compared with risk factors of patients who had definite diagnoses of infective endocarditis. There were 69 patients with bacteremia alone (76%) and 22 patients with endocarditis (24%), as verified by echocardiography. Univariate analysis showed that diabetes mellitus (P=0.024), the presence of an automatic implantable cardioverter-defibrillator/pacemaker (P=0.006) or a prosthetic heart valve (P=0.003), and recent hospitalization (P=0.048) were significantly associated with developing infective endocarditis in patients with S. aureus bacteremia. The incidence of methicillin-resistant and methicillin-sensitive S. aureus bacteremia was similar in the bacteremia and infective-endocarditis groups (P=0.437). In conclusion, identified high-risk clinical factors in the presence of bacteremia can suggest infective endocarditis. Early evaluation with transesophageal echocardiography might well be warranted.

    Objective To explore the clinical characteristics and correlated risk factors of hydrocephalus secondary to bacterial meningitis in children,in order to reduce its incidence and improve the outcome of hacterial meningitis. Methods The study was retrospectively performed on 111 patients at the First Affiliated Hospital of Guangxi Medical University, from Jan. 2004 to Jun. 2010,with the diagnosis of bacterial meningitis. All cases were divided into bacterial meningitis with hydrocephalus group and without hydrocephalus group according to neu-roimaging findings. The clinical and laboratory data of patients with and without hydroce phalus were analyzed and compared by SPSS 17.0 software. Results Hydrocephalus patients accounted for 14.4% (16/111 cases) of bacterial meningitis cases. A total of 75% (12/16 cases) hydrocephalus manifested itself within 4 weeks following the disease's onset. Fourteen cases (14/16 cases,87. 5%) were obstructive hydrocephalus. One to three times repeated CT/MRI were performed when hydrocephalus was diagnosed. Two cases with hydrocephalus required ventriculoperitoneal shunt al 2 months after bacterial meningitis was onset. Two patients with hydrocephalus were died. There were significant differences between the both groups at admission included young age,prolonged fever > 10 d,the presence of seizures,impaired consciousness, empirical treatment failure, cerebral infarction,low haemoglobin level,high cerebrospinal fluid(CSF) protein level and low CSF glucose level. The Logistic regression analysis showed that impaired consciousness,empirical treatment failure and low haemoglobin level were independent risk factors of hydrocephalus secondary to bacterial meningitis. Conclusions Hydrocephalus was one of the severe sequelaes of bacterial meningitis. Certain clinical parameters and laboratory findings in blood and CSF at the lime of admission can be used as predictors for hydrocephalus in bacterial meningitis.%目的 探讨细菌性脑膜炎并

    Modern healthcare and modern societies are facing up to the need for greater engagement of patients in treatment decisions. Shared and informed decision-making is replacing traditional paternalistic approaches to decisions; health policy both reflects and drives these changes. A critical contribution to better informed decisions by patients is the effective communication of risk in the clinical consultation. This is not straightforward, but there is a growing evidence base to improve performance in this area to the benefit of both patients and clinicians. The purpose of this review is to provide an accessible and practical guide to better communication of risk by clinicians.

    This retrospective descriptive study was conducted at Queen Sirikit National Institute of Child Health (QSNICH), Bangkok, Thailand to describe the clinical features of gastrointestinal salmonellosis in children. The medical records of 134 patients admitted to QSNICH in 2009 who had a positive stool culture for Salmonella spp were reviewed. Demographic, clinical, laboratory, treatment, culture and antimicrobial sensitivity data were collected and analyzed. The mean age of the patients was 22.9 months (range 0.5 to 158 months); 76.9% were < 2 years old. The male to female ratio was 1.5:1. Salmonella B was most commonly found serogroup (47%). The common clinical manifestations included diarrhea (99.3%), fever (93.3%), dehydration (64.9%) and nausea/vomiting (48.5%). Most of the Salmonella isolates were sensitive to a fluoroquinolone and many were sensitive to Cotrimoxazole, but few were sensitive to ampicillin. There were no significant differences in the clinical manifestations and drug sensitivities of the different Salmonella serogroups, except convulsions were more common in Salmonella E infected patients (p = 0.04) and more Salmonella C isolates were sensitive to ampicillin (p = 0.04). There was no significant correlation between clinical course and antimicrobial treatment, except the duration of diarrhea was significantly longer in patients who received antimicrobial treatment (mean 6.1, SD 4.7 days vs mean 4.2, SD 2.1 days) (p = 0.03). Three patients had Salmonella bacteremia. Three patients died but not directly due to Salmonella infection.

    Schizencephaly is an uncommon structural disorder of cerebral cortical development, characterized by congenital clefts spanning the cerebral hemispheres from the pial surface to the lateral ventricles and lined by cortical gray matter. Either an antenatal environmental incident or a genetic origin could be responsible for this lesion which occurs between the third and fourth month of gestation. We report the clinical and cranial imaging features of 30 children, of whom 15 had unilateral and 15 had bilateral lesions. Their ages at the time of the first presentation ranged from 1 month to 10 years. They were thoroughly studied from clinical, epileptical, imaging and electroencephalographic (EEG) viewpoints. Five patients were investigated by cranial computed tomography (CT), eight by cranial magnetic resonance (MR) imaging, and 17 by both methods. The clinical features consisted of mild hemiparesis in 17 cases (57%), 12/17 were related to a unilateral phenotype (80% of all unilateral forms) and 5/17 to a bilateral phenotype. A tetraparesis was present in nine cases, all of which were due to a bilateral cleft. Bilateral forms were significantly associated with tetraparesis, whereas unilateral forms were associated with hemiparesis. Mental retardation was observed in 17 cases (57%), and was observed significantly more often in bilateral clefts (80%). When both hemispheres are involved, an absence of reorganization of the brain function between the two hemispheres leads to severe mental deficits, in addition to the cerebral anomaly itself. Eleven patients had seizures (seven from unilateral and three from bilateral forms). The degree of malformation was not related to the severity of epilepsy. Migration disorders, such as dysplasia or heterotopia, were observed in 30% of cases and are also important etiopathogenetic factors. The septum pellucidum was absent in 13 cases (43%), with septo-optical dysplasia in two cases. Corpus callosum dysgenesis was noted in 30% of cases

    Full Text Available Eosinophilic esophagitis (EE is a motility disorder of the esophagus that typically presents with dysphagia. The objective of the present study was to explore patient characteristics, clinical and endoscopic features, and response to treatment of patients with EE. Patients were selected retrospectively based on a review of biopsy results from previous endoscopies performed between 2004 and 2008. A total of 54 patients (41 men and 13 women with biopsy-proven EE were included in the study. Further information regarding the patients’ clinical and endoscopic features, and response to treatment were obtained through chart reviews and patient telephone interviews. The mean age of the patients at symptom onset was 30 years. All patients complained of dysphagia, 81% had a history of bolus obstruction, 43% had a history of asthma and 70% had a history of environmental allergies. Thirty-three per cent had a family history of asthma, while 52% had a family history of food or seasonal allergies. The most common endoscopic findings were rings and/or corrugations, which were found in 63% of patients. Swallowed fluticasone therapy resulted in symptom resolution in 74% of patients; however, 79% of these patients relapsed after discontinuing fluticasone therapy and required repeat treatments. Esophageal dilation was complication free and resulted in improvement in 80% of patients. However, 83% of those reporting improvement relapsed within one year. The clinical and endoscopic findings were similar to those found in the literature, with most patients requiring ongoing, repeated therapies. Further studies are needed to assess the safety and efficacy of treatment modalities ideally suited to patients with EE.

    There is large variation in the molecular genetics and clinical features of hemoglobinopathies in Iran. Studying structural variants of hemoglobin demonstrated that the β-chain variants of hemoglobin S and D-Punjab are more prevalent in the Fars (southwestern Iran) and Kermanshah (western Iran) provinces, respectively. Also, α-chain variants of Hb Q-Iran and Hb Setif are prevalent in western Iran. The molecular basis and clinical severity of thalassemias are extremely heterogenous among Iranians due to the presence of multiethnic groups in the country. β-Thalassemia is more prevalent in northern and southern Iran. Among 52 different β-thalassemia mutations that have been identified among Iranian populations, IVSII-1 G:A is the most frequent mutation in most parts of the country. The presence of IVS I-5 G:C mutation with high frequency in southeastern Iran might reflect gene flow from neighboring countries. A wide spectrum of α-thalassemia alleles has been detected among Iranians with -α(3.7 kb) as the most prevalent α-thalassemia mutation. The prevention program of thalassemia birth in Iran has reduced the birth rate of homozygous β-thalassemia since the implementation of the program in 1997. In this review genetic epidemiology, clinical and hematological aspects of hemoglobinopathies, and the prevention programs of β-thalassemia in Iran will be discussed.

    Full Text Available Objective To analyze the clinical and cerebrospinal fluid (CSF cytological features of patients with tuberculous meningitis (TBM, to improve early diagnostic accuracy and treatment of TBM. Methods Clinical presentations, etiology and biochemical and cytological features of CSF were analyzed retrospectively among 60 adult cases with TBM hospitalized at Neurology Department of General Hospital of Ningxia Medical University from January 2005 to May 2011. Results Most patients (58/60, 96.67% had fever and headache at onset. In some patients, disturbance of consciousness (9/60, 15.00%, seizure (5/60, 8.33% occurred in 1 week and focal neurological signs developed during the course. Forty?four patients (73.33% had pulmonary tuberculosis history. In CSF examination, acid?fast bacillus positive was found in 8 patients. Positive acid ? fast myobacterium tuberculous culture was detected in 5 patients and positive myobacterium tuberculosis DNA were seen in 5 patients. The main changes of CSF were intracranial hypertension, increase of protein, and decrease of glucose. CSF presented mixed cellular response with predominace in the increasing of leucocytes. During early stage the mean percentage of neutrophil in CSF was less than 40%. After short term (as long as 2 months of regular antituberculotic therapy no significant changes in total cell count and the proportion of neutrophils were seen. In 60 patients, 44 patients were ameliorated, 11 were not healed or were discharged or transferred to other hospital and 5 were dead. Prognosis of patients treated within 3 weeks after onsets was superiorly to those treated at more than 3 weeks after onset. Conclusion There are no specific clinical features in TBM and it is hard to perform early diagnosis for TBM, particularly, existing of low efficiency in pathogenic detection, but pulmonary tuberculosis is of accessary value to diagnose TBM. Whereas mixed cellular response may complementarily provide the diagnosis of

    Background and objective Osteogenesis imperfecta (OI) comprises a group of disorders principally affecting type I collagen which result in increased bone fragility. Children with severe OI suffer recurrent fractures, resulting in severe deformity and growth stunting in many cases, with loss of independent ambulation by the teenage years in over 50% of cases. Recently, cyclical intravenous treatment with pamidronate has proven of benefit to children with severe forms of OI. This article aims to describle clinical features and laboratory manifestations of patient with OI and evaluate outcome of bisphosphonate management. Methods Clinical features, biochemical finding, and management outcome of 104 cases were study. The patients were classified into four major subtypes of Sillience et al. 1979. Patients with severe types were treatment with pamidronate (Aredia) used Rauch protocol 2003. Results Now we have 196 patients (87 females and 109 males) but we studied focus on 104 patients from 98 families (60 males, 44 females) onset at 2.1±3.0 years (median 0.35) with the average fracture bone of 5.9±4.4 times. In there, 17% type I, 8% type II, 63% type III, and 12% type IV. Clinical features include of intrauterine fracture visible on ultrasound 35%, bone deformation after birth 68%, triangle face 76%, long bone deformation 91%, chest deformation 46%, scoliosis 27%, short status 90%, blue sclera 83%, dentinogenesis imperfecta 20%, hearing loss 6%. Thirty patients have been treated with pamidronate at 3.2±3.7 years (4 months to 8 years) during 13±0.8 months (6-30 months). Fourteen patients had fracture bone after 6 months of treatment but no patients had fracture bone after 12 months. Seven patients had been treatment after 1.6±0.5 years, BMD increase from 0.39±0.311 to 0.79±0.105 g/cm2 (P<0.05). One patient had fever reaction after first pamidronate infusion but controlled with standard antipyretic therapy, and do not recur in later treatments. Conclusions OI has

    Using case reports and a review of the literature, the clinical features of envenomation by the genus of Australian funnel web spiders known as Hadronyche, are characterised. Five cases are reported here, including the first life-threatening envenomation by Hadronyche species 14 (the Port Macquarie funnel web). Two severe envenomations by Hadronyche cerberea (the Southern Tree funnel web) and one each by Hadronyche formidabilis (the Northern Tree funnel web) and Hadronyche infensa (the Darling Downs funnel web) are also described. The clinical experience of the authors' provided the five cases described in detail one of which has previously been reported in brief. Eight cases of Hadronyche envenomation from the literature (Medline 1966-1998 and Embase 1980-1998) were analysed in order to draw comparisons between this syndrome and the well described envenomation syndrome of Atrax robustus (the Sydney funnel web). Reports of funnel web spider antivenom use to Commonwealth Serum Laboratories (CSL) between 1995 and June 1998 were also examined. The biology of these dangerous spiders, their geographic distribution, venom characteristics and management issues are addressed. It is concluded that bites from at least six Hadronyche species have produced a life-threatening envenomation syndrome clinically indistinguishable from that of Atrax robustus. Atrax robustus derived antivenom is effective although antivenom requirements may be greater than for Atrax envenomation. Antivenom supplies are limited and sufficient stocks to treat a severe envenomation are unlikely to be found in any one institution. Pressure-immobilisation first aid is effective in delaying onset of envenomation, may enhance local inactivation of venom and early removal can result in rapid clinical deterioration.

    Because of the difficulties of ascertaining episode of hypomania by past history of the patients, it is of clinical value to find variables which predict the development of bipolar II disorder in depressive patients. Taking advantage of relatively long hospitalization, the authors tried to elucidate fine clinical features of the soft bipolarity. The subjects were 39 patients with Major Depressive Episode, diagnosed according to the 4th edition of the Diagnostic and Statistical Manual criteria. Among them, 15 patients were diagnosed as bipolar II disorder (BPII), whereas 24 patients were with unipolar depression (UP), using a structured clinical interview to assess the mood spectrum (SCI-MOODS). In addition to ordinary clinical and demographic variables, the authors studied fine symptomatology of depression, premorbid personality, and interpersonal relationship. Continuous variables were analyzed by t-test. Categorical variables were tested by chi2 analysis. In terms of premorbid personality, manic type (Zerssen) was found more frequently in BPII (UP 2/24, BPII 9/15, P < 0.05). Patients with BPII tended to show apparently quick disappearance of depressive symptoms (UP 2/24, BPII 9/15, P = 0.01). The most prominent result was a high prevalence of comorbidity of borderline personality disorder (BPD) among BPII (UP 0/24, BPII 6/15, P = 0.02). As Akiskal indicated that mood lability represents the most powerful predictor of hypomanias, patients with BPII showed quick response in mood to admission. The current subjects with BPII had high frequency of manic type of premorbid personality, indicating the usefulness of this variable for the prediction of hypomanias. Finally, the authors could observe development of BPD during hospitalization exclusively among BPII, to support the possibility of BPD as a state effect of BPII.

    Full Text Available Abstract Aorto-atrial fistulas (AAF are rare but important pathophysiologic conditions of the aorta and have varied presentations such as acute pulmonary edema, chronic heart failure and incidental detection of the fistula. A variety of mechanisms such as aortic dissection, endocarditis with pseudoaneurysm formation, post surgical scenarios or trauma may precipitate the fistula formation. With increasing survival of patients, particularly following complex aortic reconstructive surgeries and redo valve surgeries, recognition of this complication, its clinical features and echocardiographic diagnosis is important. Since physical exam in this condition may be misleading, echocardiography serves as the cornerstone for diagnosis. The case below illustrates aorto-left atrial fistula formation following redo aortic valve surgery with slowly progressive symptoms of heart failure. A brief review of the existing literature of this entity is presented including emphasis on echocardiographic diagnosis and treatment.

    To describe the US findings of corpus luteum cyst rupture in order to elucidate the associated clinical features. Twenty patients with proven corpus luteum cyst rupture were included in this study. The US findings of these patients were retrospectively analyzed in terms of the presence of designable cyst, size of the cyst, thickness and blood flow of the cyst wall, extension and echogenicity of peritoneal fluid, and involved site (right or left ovary). We also surveyed the clinical features such as the onset period according to the menstrual cycle, and the presence of suspectable cause. Fourteen of the 20 patients revealed designable cysts (mean diameter of 2.6 cm) with thick walled cysts (mean thickness, 4.6 mm, 2.4-6.8 mm) and increased blood flow. Six patients didn't reveal any cyst but only hematoma in adnexa. All patients had hemoperitoneum in the pelvic cavity, and the hemoperitoneum was extended to Morrison's pouch in 8 patients and to the subphrenic space in 6. The cysts occurred in the right adnexa in 15 patients and in the left in 5. Mean interval from the last menstrual period (LMP) was 26 days (13-44 days) and 6 of the 8 patients for whom it had been possible to obtain detailed history taking had had coitus just before the occurrence of symptom. When women who are hospitalized for acute abdomen and who are in luteal phase reveal US findings of hematoma or thick-walled cyst in adnexa and hemoperitoneum, a corpus luteum cyst rupture is highly suspected. In our case study the corpus luteum cyst rupture predominantly occurred in the right side, and the most suspectable cause was trauma such as coitus in the luteal phase

    Introduction Laryngeal tuberculosis (LTB) is the most frequent granulomatous disease of the larynx and represents less than 2% of extrapulmonary TB cases. There are no pathognomonic clinical and endoscopic features of this disease and studies on LTB that can assist in its diagnostic characterization are lacking. Objective To identify factors associated with clinical and topographical features of LTB. Method a retrospective cross-sectional study was conducted from the medical records of 36 patients with confirmed LTB diagnosis. Results Dysphonia and cough were the main symptoms presented by patients and the true vocal folds the most frequently affected site. The average of the duration of the disease evolution was significantly higher in patients with dysphonia than in patients without this symptom. We observed association between dysphonia and true vocal fold lesions and between odynophagia and lesions in the epiglottis, arytenoids and aryepiglottic folds. Odynophagia was more frequent in individuals with lesions in four or more laryngeal sites. Weight loss equal or above 10% of the body weight was more frequent in patients with odynophagia as first symptom and in patients with ulcerated lesion. Dyspnea on exertion was more frequent in individuals with more extensive laryngeal lesions. The percentage of smokers with lesions in four or more laryngeal sites was greater than that found in non-smokers. Laryngeal tissue fragment bacilloscopy and culture examinations were less positive than sputum ones. Conclusions Smoking appears to be associated with the development of more extensive LTB lesions, and LTB with dyspnea on exertion and odynophagia with consequent impairment of nutritional status. We emphasize the need for histopathologic confirmation, once positive sputum bacteriological examinations seem not to necessarily reflect laryngeal involvement. PMID:27077734

    Objective To investigate clinical features of pheochromocytoma and summarize experiences of anesthetic management during the perioperative period. Methods Two hundred and fifty eight patients who were diagnosed with pheochromocytoma in our hospital were reviewed retrospectively for clinical features. According to different preoperative pharmalogical preparations, perioperative mortalities were analyzed in three periods (Period 1: January 1955-December 1975; Period 2: January 1976-December 1994; Period 3: January 1995-July 2001). In Period 3, hemodynamic changes in the patients undergoing different anesthetic methods were analyzed. Results About 5.8% (15/258) of pheochromocytoma was an integral part of multiple endocrine neoplasia (MEN) type Ⅱ or mixed type. Sixty percent (149/249) of the patients who had undergone surgery possessed evidence of catecholamine cardiac toxicity preoperatively. Impaired glucose tolerance was found in 59% (147/249) of the patients before surgery. Perioperative mortality was significantly decreased from 8% (5/60) in Period 1 to 1.2% (1/75) in Period 2 (P<0.01). No perioperative deaths occurred in Period 3. The volume infused during the operation was significantly higher both in the epidural anesthesia group (3474 ml±624 ml, P<0.01) and in the epidural plus general anesthesia group (3654 ml±475 ml, P<0.01) than in the general anesthesia group (2534 ml±512 ml). There were favorable hemodynamic characteristics in patients before removal of the tumor in the epidural anesthesia group and in the epidural plus general anesthesia group, as compared with the general anesthesia group. Conclusions A positive surgical outcome of the excision of pheochromocytoma depends on multiple factors, including careful assessment of potential vital organ damage before surgery and restoration of blood volume by establishing α-blockade preoperatively, meticulous anesthetic management of patients during surgery, and appropriate circulatory support after

    A study of the neuromuscular features of acromegaly was performed in six patients. Clinical assessment was supplemented by quadriceps force measurements, plasma creatine kinase (CK) activities, electromyography (EMG) and nerve conduction studies. Muscle mass was measured by urinary creatinine/height indices (CHI) and cross sectional area (CSA) of thighs and calves on computed tomography. Quadriceps force/unit cross sectional area was derived. Needle biopsies of vastus lateralis were studied by histochemical and ultrastructural methods. Mean fibre area (MFA) and fibre type proportions were measured. Most of the subjects studied had muscle pain and proximal muscle weakness confirmed by quadriceps force measurements. This occurred in the absence of muscle wasting, as shown by cross sectional area measurements and normal or raised creatinine/height indices. "Myopathic" features were demonstrated by needle biopsy in half the patients and occasionally by electromyography and raised plasma creatine kinase activity. Abnormalities on needle biopsy included variation in fibre size, type 2 fibre atrophy and large type 1 MFA relative to type 2 MFA. Electronmicroscopy showed the non-specific findings of increased glycogen accumulation, excess lipofuscin pigment and myofilament loss.

    The authors discuss the diagnostic criteria for pedophilia and review the literature on its clinical features, including data on prevalence, gender, age of onset, number of victims, frequency and type of acts, violence, impulsivity, and insight. Findings concerning the characteristics of victims (e.g., sex, age, relationship to the pedophile) and research on pedophilic subtypes-exclusive versus nonexclusive; incestuous versus nonincestuous; heterosexual, homosexual, or bisexual-are reviewed. Studies have shown that pedophiles may share many psychiatric features beyond deviant sexual desire, including high rates of comorbid axis I disorders (affective disorders, substance use disorders, impulse control disorders, other paraphilias) as well as severe axis II psychopathology (especially antisocial and Cluster C personality disorders). The authors present several possible etiological models for pedophilia and conclude that further research is needed concerning the etiological role of a childhood history of sexual abuse as well as the underlying neurobiology of deviant sexual arousal and decreased erotic differentiation. Finally, findings concerning pharmacological and cognitive-behavioral treatments for pedophilia are briefly reviewed. Recidivism, drop-out, and noncompliance are significant problems in the treatment of pedophilia. The authors review predictors of treatment outcome and conclude that pedophilia is extremely difficult to treat and that effective treatment needs to be intensive, long-term, and comprehensive, possibly with lifetime follow-up.

    Full Text Available Macrophagic myofasciitis (MMF is an emerging condition characterized by specific muscle lesions assessing abnormal long-term persistence of aluminium hydroxide within macrophages at the site of previous immunization. Affected patients usually are middle-aged adults, mainly presenting with diffuse arthromyalgias, chronic fatigue, and marked cognitive deficits, not related to pain, fatigue or depression. Clinical features usually correspond to that observed in chronic fatigue syndrome/myalgic encephalomyelitis. Representative features of MMF-associated cognitive dysfunction include dysexecutive syndrome, visual memory impairment and left ear extinction at dichotic listening test. Most patients fulfil criteria for non-amnestic/dysexecutive mild cognitive impairment, even if some cognitive deficits appear unusually severe. Cognitive dysfunction seems stable over time despite marked fluctuations. Evoked potentials may show abnormalities in keeping with central nervous system involvement, with a neurophysiological pattern suggestive of demyelination. Brain perfusion SPECT shows a pattern of diffuse cortical and subcortical abnormalities, with hypoperfusions correlating with cognitive deficiencies. The combination of musculoskeletal pain, chronic fatigue and cognitive disturbance generates chronic disability with possible social exclusion. Classical therapeutic approaches are usually unsatisfactory making patient care difficult.

    Full Text Available Objective: The aim of this study was to determine the prevalence of macroprolactin in patients with hyperprolactinemia in our region, and to determine the clinical and neuroradiological features of the affected individuals. Materials and Methods: We used the Roche Elecsys Prolactin assay (Prolactin II with polyethylene glycol precipitation to identify macroprolactin; recovery of ≤40% was considered to represent significant macroprolactinemia. Of 156 consecutive patients with hyperprolactinemia, macroprolactin was found in ten (6.4%. Clinical records of these patients were reviewed. Results: Of ten patients with macroprolactinemia, two males presented with infertility and two with decreased libido and erectile dysfunction. Females presented with menstrual dysfunction, with or without infertility. Pituitary adenomas were identified in two of seven patients who underwent neuroimaging. Dopamine agonists were prescribed to seven patients; their symptoms were not affected by this therapy. Conclusions: Macroprolactin is a cause of misdiagnosis and inappropriate treatment in patients with hyperprolactinemia. It is important to be aware of the extent to which the assay system used in the measurement of prolactin may detect macroprolactin, and to have a available validated method to confirm its presence. This will ensure appropriate management for patients with this benign condition. Turk Jem 2008; 12: 46-9

    The aim of this study was to investigate the clinical features and treatment results of endophthalmitis after cataract surgery. Five patients with endophthalmitis after phacoemulsification with intraocular lens implantation were enrolled in this study. The pathogenesis, clinical manifestation, and surgical outcomes of 5 patients were compared. Three patients were surgically treated with anterior chamber irrigation and vitrectomy with intravitreal injection. The remaining two patients were medically treated with an intravitreal injection of vancomycin and ceftazidime. Treatment results of the five patients were analyzed. Four patients had positive cultures for bacteria (two cases Staphylococcus epidermidis, one case Enterococcus faecalis, and one case head-like Staphylococcus). The culture of the fifth patient did not have bacterial growth. One year following treatment, four patients had restored visual acuity and a clear vitreous cavity. Retinal detachment and other complications were not observed. The remaining patient had a visual acuity of index at 30 cm one year following treatment. For patients with endophthalmitis after cataract surgery, a biochemical laboratory examination should be promptly performed and should include a bacterial culture and drug sensitivity test. When necessary, vitrectomy combined with an intravitreal injection of vancomycin should be performed to treat the infection early and to help retain useful vision.

    Full Text Available Background: There have been few reports on primary cicatricial alopecias (PCR especially from Asia (PCA. Aims: To study the clinical, pathological and dermoscopic characteristics of PCA among Chinese patients. Methods: A retrospective analysis of the clinical data of 59 patients with PCA was conducted and the dermoscopic, pathological, treatment and prognosis characteristics analyzed. Fisher′s Chi-square exact test, Kruskal-Wallis and Spearman rank correlation test were performed. Results: The ratio of neutrophilic to lymphocytic cicatricial alopecias was about 1.3:1 in this group. The most frequent disorder was folliculitis decalvans. Follicular openings were absent on dermoscopy in all cases except alopecia mucinosa. Patulous follicular openings were characterisitc of alopecia mucinosa. After treatment, an increase in short vellus hairs was the earliest feature, while telangiectasia, epidermal scale, follicular hyperkeratosis, pustules and hair diameter diversity gradually decreased or even disappeared. Improvement in the areas of hair loss after treatment was seen more often in discoid lupus erythematosus, folliculitis decalvans and dissecting cellulitis than in patients with classic pseudopelade of Brocq. Nine patients (13.6% relapsed after cessation of therapy. Female patients needed longer treatment times. Long duration, large areas of hair loss and shorter treatment courses were the major factors in relapses. Conclusions: Dermatoscopy provides a rapid, practical and useful aid for the diagnosis of PCA and also to assess disease activity. Patulous follicular openings are a specific dermoscopic sign of alopecia mucinosa. Lichen planopilaris is less common in China than in the West.

    AIM: To summarize clinical features of probable severe acute respiratory syndrome (SARS) in Beijing.METHODS: Retrospective cases involving 801 patients admitted to hospitals in Beijing between March and June 2003, with a diagnosis of probable SARS, moderate type.The series of clinical manifestation, laboratory and radiograph data obtained from 801 cases were analyzed. RESULTS: One to three days after the onset of SARS, the major clinical symptoms were fever (in 88.14% of patients), fatigue, headache, myalgia, arthralgia (25-36%), etc. The counts of WBC (in 22.56% of patients) lymphocyte (70.25%)and CD3, CD4, CD8 positive T cells (70%) decreased. From 4-7 d, the unspecific symptoms became weak; however, the rates of low respiratory tract symptoms, such as cough (24.18%), sputum production (14.26%), chest distress (21.04%) and shortness of breath (9.23%) increased, so did the abnormal rates on chest radiograph or CT. The low counts of WBC, lymphocyte and CD3, CD4, CD8 positiveT cells touched bottom. From 8 to 16 d, the patients presented progressive cough (29.96%), sputum production (13.09%), chest distress (29.96%) and shortness of breath (35.34%). All patients had infiltrates on chest radiograph or CT, some even with multi-infiltrates. Two weeks later, patients' respiratory symptoms started to alleviate, the infiltrates on the lung began to absorb gradually, the counts of WBC, lymphocyte and CD3, CD4, CD8 positive T cells were restored to normality.CONCLUSION: The data reported here provide evidence that the course of SARS could be divided into four stages, namely the initial stage, progressive stage, fastigium and convalescent stage.

    Full Text Available The World Health Organization has declared tuberculosis (TB to be a global emergency, as it remains the most common single cause of morbidity and mortality worldwide. TB is caused by the acid-fast bacillus Mycobacterium tuberculosis and primarily affects the lungs [pulmonary TB (PTB]. It can also affect any other part of the body [extrapulmonary TB (EPTB]. It is estimated that 1.4% of patients with PTB will eventually develop ocular disease; however, in the majority of cases of ocular TB, PTB may not be documented. Ocular TB infection is usually a result of hematogenous spread during PTB or EPTB. Symptomatic disease most commonly develops after reactivation of dormant foci in the ocular tissue rather than being the manifestation of the initial infection. Immune-mediated ocular TB can occur due to hypersensitivity to M. tuberculosis antigens from a distant focus (such as lungs, despite the absence of the bacterium in the eye. The most common clinical presentation of intraocular inflammation (uveitis due to TB appears to be posterior uveitis, followed by anterior uveitis, panuveitis and intermediate uveitis. The absence of uniform diagnostic criteria for intraocular TB has led to confusion regarding its diagnosis and management. Recent studies on the clinical importance of purified protein derivative (PPD skin test, interferon-gamma release assays, chest computed tomography and polymerase chain reaction have provided a new approach to diagnosing ocular TB. This review series focuses on the clinical features, diagnostic techniques, diagnostic criteria, and treatment modalities in the light of recent literature. (Turk J Ophthalmol 2011; 41: 171-81

    Full Text Available Aim: to show the clinical features of subacute course of subacute course of radiation disease and how they differ from the typical manifestations of acute and chronic radiation syndrome. Material and methods. Materials of the Burnasyan Federal Medical and Biophysical Center Register of acute radiation disease (ARS in the Former USSR and Russia and Materials of a Burnasyan Federal Medical and Biophysical Center database of workers "Mayak" with chronic radiation syndrome (CRS were analyzed. There were selected 22 patients with radiation syndrome due to fractionated or prolonged accidental exposure (the main group of patients. There were formed two subgroups for comparison: patients with a typical marrowy syndrome of acute radiation disease and with chronic radiation syndrome. Statistical analysis of results was made by means of statistical software package Statistica v. 6.1 for Windows (StatSoft Inc., USA and Microsoft Excel 2010. Results. It was found that subacute course of radiation syndrome is possible under radiation exposure with medium dose rate in the range of 0.1-0.3 Gy/day Early symptoms of the disease as a primary reaction symptoms are completely absent. First complaints appeared in the earliest one month after the start of work in adverse conditions, on the average 6 months. In the period of formation there is a pancytopenia in the peripheral blood. Duration of the formation period was also determined. In this case radiation cataracts in patients are not observed. After the termination of radiation exposure hematopoietic recovery is slow, possibly incomplete with a high probability of hemoblastosis development. Conclusions. There has been described the subacute course of radiation disease by analyzing the clinical material of patients with radiation syndrome, there has been analyzed the clinical criteria that distinguish subacute radiation syndrome from acute and chronic.

    X-linked agammaglobulinemia (XLA) is caused by BTK mutations, patients typically show <2% of peripheral B cells and reduced levels of all immunoglobulins; they suffer from recurrent infections of bacterial origin; however, viral infections, autoimmune-like diseases, and an increased risk of developing gastric cancer are also reported. In this work, we report the BTK mutations and clinical features of 12 patients diagnosed with XLA. Furthermore, a clinical revision is also presented for an additional cohort of previously reported patients with XLA. Four novel mutations were identified, one of these located in the previously reported mutation refractory SH3 domain. Clinical data support previous reports accounting for frequent respiratory, gastrointestinal tract infections and other symptoms such as the occurrence of reactive arthritis in 19.2% of the patients. An equal proportion of patients developed septic arthritis; missense mutations and mutations in SH1, SH2 and PH domains predominated in patients who developed arthritis.

Current research is sparse and present guidelines are not adapted to this group of patients.Objectives: We present a literature review on clinical characteristics, comorbidities, and cognitive impairment in patients with late-life BD. This review discusses common comorbidities that affect BD elders and how aging might affect cognition and treatment.Methods: Eligible studies were identified in MedLine by the Medical Subject Headings terms “bipolar disorder” and “aged”. We only included original research reports published in English between 2012 and 2015.Results: From 414 articles extracted, 16 studies were included in the review. Cardiovascular and respiratory conditions, type II diabetes, and endocrinological abnormalities were observed as highly prevalent. BD is associated with a high suicide risk. Bipolar elderly had an increased risk of dementia and performed worse on cognitive screening tests compared to age-matched controls across different levels of cognition. Despite high rates of medical comorbidity among bipolar elderly, a systematic under-recognition and undertreatment of cardiovascular disease have been suggested.Conclusion: There was a high burden of physical comorbidities and cognitive impairment in late-life BD. Bipolar elderly might be under-recorded and undertreated in primary medical care, indicating that

    Background Pathological fractures signify a potentially more aggressive subset of the original disease with higher misdiagnosis rates and inferior oncologic results.The purpose of the present study was to explore the clinical features of neoplastic pathological fracture in extremities.Methods From August 2002 to December 2010,a consecutive series of 139 patients suffering neoplastic pathological fracture were recruited,including 79 males and 60 females with a mean age of 31.3 years.Fractures were classified into five groups:tumor-like lesions (55),benign bone tumors (13),giant cell tumors (7),primary malignant bone tumors (28),and metastatic bone tumors (36).Based on their inducing forces,pathologic fractures were classified into four grades:spontaneous fracture,functional fracture,minor injury,and traumatic injury.Patients' age,fracture site,histological diagnoses,fracture forces,prodromes,and misdiagnosis were well reviewed.Kruskal-Wallis and x2 tests were used to compare forces and prodromes within different types of bone tumors.Results The highest pathologic fracture morbidity was 32.3% (45/139),which lay in the 11-20 year group,and 86.1%of metastatic tumors occurred in the 50-80 year group.The common sites of fractures were femur,humerus,and tibia.The fracture forces in benign bone tumors and tumor-like lesions are the strongest,followed by metastatic tumors and primary malignant bone tumors (Hc=80.980,P=0.000).Sixty-seven patients (48.2%) had local prodromes before pathologic fracture.The incidence rates of prodromes between primary malignant tumors and metastatic bone tumors had no significant difference (P=0.146),but they were all obviously higher than that of benign bone tumors and tumor-like lesions.Twenty patients experienced misdiagnosis.Conclusion Minor injury forces and local prodromes are clinical features of neoplastic pathologic fractures and they are also the critical factor avoiding misdiagnoses.

    Full Text Available Abstract Background Falls in the elderly is nowadays a major concern because of their consequences on elderly general health and moral states. Moreover, the aging of the population and the increasing life expectancy make the prediction of falls more and more important. The analysis presented in this article makes a first step in this direction providing a way to analyze gait and classify hospitalized elderly fallers and non-faller. This tool, based on an accelerometer network and signal processing, gives objective informations about the gait and does not need any special gait laboratory as optical analysis do. The tool is also simple to use by a non expert and can therefore be widely used on a large set of patients. Method A population of 20 hospitalized elderlies was asked to execute several classical clinical tests evaluating their risk of falling. They were also asked if they experienced any fall in the last 12 months. The accelerations of the limbs were recorded during the clinical tests with an accelerometer network distributed on the body. A total of 67 features were extracted from the accelerometric signal recorded during a simple 25 m walking test at comfort speed. A feature selection algorithm was used to select those able to classify subjects at risk and not at risk for several classification algorithms types. Results The results showed that several classification algorithms were able to discriminate people from the two groups of interest: fallers and non-fallers hospitalized elderlies. The classification performances of the used algorithms were compared. Moreover a subset of the 67 features was considered to be significantly different between the two groups using a t-test. Conclusions This study gives a method to classify a population of hospitalized elderlies in two groups: at risk of falling or not at risk based on accelerometric data. This is a first step to design a risk of falling assessment system that could be used to provide

    Cluster headache (CH) is a rare underdiagnosed primary headache disorder with very severe unilateral pain and autonomic symptoms. Clinical characteristics of Korean patients with CH have not yet been reported. We analyzed the clinical features of CH patients from 11 university hospitals in Korea. Among a total of 200 patients with CH, only 1 patient had chronic CH. The average age of CH patients was 38.1 ± 8.9 years (range 19–60 years) and the average age of onset was 30.7 ± 10.3 years (range 10–57 years). The male-to-female ratio was 7:1 (2.9:1 among teen-onset and 11.7:1 among twenties-onset). Pain was very severe at 9.3 ± 1.0 on the visual analogue scale. The average duration of each attack was 100.6 ± 55.6 minutes and a bout of CH lasted 6.5 ± 4.5 weeks. Autonomic symptoms were present in 93.5% and restlessness or agitation was present in 43.5% of patients. Patients suffered 3.0 ± 3.5 (range 1–25) bouts over 7.3 ± 6.7 (range 1–30) years. Diurnal periodicity and season propensity were present in 68.5% and 44.0% of patients, respectively. There were no sex differences in associated symptoms or diurnal and seasonal periodicity. Korean CH patients had a high male-to-female ratio, relatively short bout duration, and low proportion of chronic CH, unlike CH patients in Western countries. PMID:28145655

    Background An increasing incidence of Crohn' s disease has been found in China in recent years.Our study has been focused on evaluating the diversity of the clinical manifestations of Crohn' s disease in order to improve early diagnostic accuracy and therapeutic efficacy.Methods Thirty patients with active Crohn's disease were enrolled and their clinical data, including diagnostic and therapeutic results, were analyzed. Endoscopy combined with histological examination of biopsy specimens provided characteristic features of the disease. Transabdominal bowel sonography (TABS) was used for detecting intestinal complications. Nutritional supportive therapy was given to 20 subjects with active cases of the disease.Results Most patients were young adults with a higher proportion of females to males (ratio: 1.14:1). The disease affects any segment or a combination of segments along with the alimentary tract(from the mouth to the anus). In this study, the colon and small bowel were the major sites involved.Recurrent episodes of abdominal pain in the right lower quadrant and watery diarrhea were the most common symptoms. Granulomas were identifiable in nearly one-third (30.8%) of all biopsy specimens. In moderate cases of the disease, remission was achieved more quickly through the use of oral prednisone therapy than with SASP or 5-ASA. Beneficial effects on the host' s nutritional status were observed. Immunosuppressives were used on an individual basis and showed variable therapeutic effects. Sixteen patients had surgery due to intestinal obstruction or failure to respond to drug therapies. Rapid improvement after surgery was reported. Conclusion Endoscopy (with biopsy) and TABS were both crucial procedures for diagnosis. SASP(or 5-ASA) and prednisone were effective as inductive therapies. Azathioprine has demonstrable benefits after induction therapy with prednisone. Surgery, as an alternative treatment, provided another effective choice in selected patients.

Material and Method: The records of 35 patients with orbital neurogenic tumors who were diagnosed and treated at Ankara University Faculty of Medicine, Department of Ophthalmology, between 1998 and 2011 were evaluated retrospectively. Results: Orbitotomy via a cutaneous approach was performed in 21 (60% cases and orbitotomy via a transconjunctival approach was performed in 7 (20% cases. Three (8% cases had been operated at different centers. Four (12% cases were diagnosed clinically. Total excisional biopsy was performed in 11 (31.4% cases, subtotal excisional biopsy was performed in 7 (20%, and incisional biopsy was performed in 10 (28.6% cases. 14 (40% 35 cases were diagnosed as meningioma, 12 (34% as peripheral nerve sheath tumor, and 9 (26% cases were diagnosed as optic nerve glioma. Six (43% meningioma cases were optic nerve sheath meningioma, 5 (36% were sphenoid wing meningioma, 2 (14% were ectopic meningioma, and 1 (7% was perisellar meningioma. Six (50% of peripheral nerve sheath tumors were schwannoma, 2 (16% were solitary neurofibroma, 4 (34% were plexiform neurofibroma. External beam radiotherapy was performed in 15 (42.8% cases, cyberknife radiosurgery in 1 (2.8% , chemotherapy in 1 (2.8%, and enucleation ( because of neovascular glaucoma and vitreous hemorrhage was performed in 1 (2.8% case. Discussion: The most common orbital neurogenic tumors are meningioma, peripheral nerve sheath tumor, and optic nerve glioma. For meningioma and glioma, external beam radiotherapy is required; for schwannoma and solitary neurofibroma, total excisional biopsy is the preferred treatment. The success of visual and anatomic results are high after treatment. (Turk J Ophthalmol 2013; 43: 335-9

    Glutaric aciduria type 1 is a rare neurometabolic disease with high morbidity. To describe the MR imaging abnormalities in glutaric aciduria type 1 and to identify any association between the clinical and imaging features. MRI scans of 29 children (mean age: 16.9 months) with confirmed diagnosis of glutaric aciduria type 1 were retrospectively reviewed. Gray matter and white matter scores were calculated based on a previously published pattern-recognition approach of assessing leukoencephalopathies. Hippocampal formation and opercular topography were assessed in relation to the known embryological basis. MRI scores were correlated with morbidity score. The most consistent MRI abnormality was widened operculum with dilatation of the subarachnoid spaces surrounding underdeveloped frontotemporal lobes. Incomplete hippocampal inversion was also seen. The globus pallidus was the most frequently involved gray matter structure (86%). In addition to the central tegmental tract, white matter abnormalities preferentially involved the central and periventricular regions. The morbidity score correlated with the gray matter abnormality score (P = 0.004). Patients with dystonia had higher gray matter and morbidity scores. Morbidity is significantly correlated with abnormality of gray matter, rather than white matter, whether secondary to acute encephalopathic crisis or insidious onset disease. (orig.)

    Mucocele is a benign lesion occurring in the buccal mucosa as a result of the rupture of a salivary gland duct and consequent outpouring of mucin into soft tissue. It is usually caused by a local trauma, although in many cases the etiology is uncertain. Mucocele is more commonly found in children and young adults, and the most frequent site is the lower inner portion of the lips. Fibroma, on the other hand, is a benign tumor of fibrous connective tissue that can be considered a reactionary connective tissue hyperplasia in response to trauma and irritation. They usually present hard consistency, are nodular and asymptomatic, with a similar color to the mucosa, sessile base, smooth surface, located in the buccal mucosa along the line of occlusion, tongue and lip mucosa. Conventional treatment for both lesions is conservative surgical excision. Recurrence rate is low for fibroma and high for oral mucoceles. This report presents a series of cases of mucocele and fibroma treated by surgical excision or enucleation and the respective follow-up routine in the dental clinic and discusses the features to be considered in order to distinguish these lesions from each other.

    Full Text Available BACKGROUND: Morgellons is a poorly characterized constellation of symptoms, with the primary manifestations involving the skin. We conducted an investigation of this unexplained dermopathy to characterize the clinical and epidemiologic features and explore potential etiologies. METHODS: A descriptive study was conducted among persons at least 13 years of age and enrolled in Kaiser Permanente Northern California (KPNC during 2006-2008. A case was defined as the self-reported emergence of fibers or materials from the skin accompanied by skin lesions and/or disturbing skin sensations. We collected detailed epidemiologic data, performed clinical evaluations and geospatial analyses and analyzed materials collected from participants' skin. RESULTS: We identified 115 case-patients. The prevalence was 3.65 (95% CI = 2.98, 4.40 cases per 100,000 enrollees. There was no clustering of cases within the 13-county KPNC catchment area (p = .113. Case-patients had a median age of 52 years (range: 17-93 and were primarily female (77% and Caucasian (77%. Multi-system complaints were common; 70% reported chronic fatigue and 54% rated their overall health as fair or poor with mean Physical Component Scores and Mental Component Scores of 36.63 (SD = 12.9 and 35.45 (SD = 12.89, respectively. Cognitive deficits were detected in 59% of case-patients and 63% had evidence of clinically significant somatic complaints; 50% had drugs detected in hair samples and 78% reported exposure to solvents. Solar elastosis was the most common histopathologic abnormality (51% of biopsies; skin lesions were most consistent with arthropod bites or chronic excoriations. No parasites or mycobacteria were detected. Most materials collected from participants' skin were composed of cellulose, likely of cotton origin. CONCLUSIONS: This unexplained dermopathy was rare among this population of Northern California residents, but associated with significantly reduced health

    2007-01-01

    Full Text Available Infection with Brucella spp. continues to pose a human health risk globally despite strides in eradicating the disease from domestic animals. Brucellosis has been an emerging disease since the discovery of Brucella melitensis by Sir David Bruce in 1887. Although many countries have eradicated B. abortus from cattle, in some areas B. melitensis and B. suis have emerged as causes of this infection in cattle, leading to human infections. Currently B. melitensis remains the principal cause of human brucellosis worldwide including India. The recent isolation of distinct strains of Brucella from marine mammals as well as humans is an indicator of an emerging zoonotic disease. Brucellosis in endemic and non-endemic regions remains a diagnostic puzzle due to misleading non-specific manifestations and increasing unusual presentations. Fewer than 10% of human cases of brucellosis may be clinically recognized and treated or reported. Routine serological surveillance is not practiced even in Brucella - endemic countries and we suggest that this should be a part of laboratory testing coupled with a high index of clinical suspicion to improve the level of case detection. The screening of family members of index cases of acute brucellosis in an endemic area should be undertaken to pick up additional unrecognised cases. Rapid and reliable, sensitive and specific, easy to perform and automated detection systems for Brucella spp. are urgently needed to allow early diagnosis and adequate antibiotic therapy in time to decrease morbidity / mortality. The history of travel to endemic countries along with exposure to animals and exotic foods are usually critical to making the clinical diagnosis. Laboratory testing is indispensable for diagnosis. Therefore alertness of clinician and close collaboration with microbiologist are essential even in endemic areas to correctly diagnose and treat this protean human infection. Existing treatment options, largely based on

    Background. Frozen shoulder syndrome is a common musculoskeletal disease of idiopathic Parkinson's disease (PD) that causes long-term pain and physical disability. A better understanding of the associated factors can help identify PD patients who will require prevention to improve their quality of life. Methodology. This prospective study evaluated 60 shoulders of 30 PD patients. Correlation analysis was used to evaluate the relationships between clinical factors and shoulder sonography findings. Results. Frozen shoulder syndrome was found in 14 of 30 PD patients affecting 19 shoulders, including bilateral involvement in five and unilateral involvement in nine. There was a significant positive correlation between the parameters of sonography findings and frozen shoulder syndrome (i.e., thickness of bicipital effusion and tendon thickness of the subscapularis and supraspinatus) and mean ipsilateral Unified Parkinson's Disease Rating Scale (UPDRS) III and its subscores (tremor, rigidity, and bradykinesia scores). Conclusions. Higher ipsilateral UPDRS and subscores are associated with increased effusion around the biceps tendon, with increased tendon thickness of subscapularis and supraspinatus. Preventing frozen shoulder syndrome in the high-risk PD group is an important safety issue and highly relevant for their quality of life.

    Full Text Available David KC Cooper,1 David Ayares21Thomas E Starzl Transplantation Institute, University of Pittsburgh Medical Center, Pittsburgh, PA, USA; 2Revivicor, Blacksburg, VA, USAAbstract: The transplantation of organs and cells from pigs into humans could overcome the critical and continuing problem of the lack of availability of deceased human organs and cells for clinical transplantation. Developments in the genetic engineering of pigs have enabled considerable progress to be made in the experimental laboratory in overcoming the immune barriers to successful xenotransplantation. With regard to pig organ xenotransplantation, antibody- and cell-mediated rejection have largely been overcome, and the current major barrier is the development of coagulation dysregulation. This is believed to be due to a combination of immune activation of the vascular endothelial cells of the graft and molecular incompatibilities between the pig and primate coagulation–anticoagulation systems. Pigs with new genetic modifications specifically directed to this problem are now becoming available. With regard to less complex tissues, such as islets (for the treatment of diabetes, neuronal cells (for the treatment of Parkinson's disease, and corneas, the remaining barriers are less problematic, and graft survival in nonhuman primate models extends for >1 year in all three cases. In planning the initial clinical trials, consideration will be concentrated on the risk–benefit ratio, based to a large extent on the results of preclinical studies in nonhuman primates. If the benefit to the patient is anticipated to be high, eg, insulin-independent control of glycemia, and the potential risks low, eg, minimal risk of transfer of a porcine infectious agent, then a clinical trial would be justified.Keywords: infection, pigs, genetically-engineered, xenotransplantation, islets, xenotransplantation, organs

    Objective To investigate the clinical features and management of bronchogenic cyst in the adults. Methods We retrospectively reviewed 50 patients admitted to our hospital with histopathologically proved bronchogenic cyst from January 1983 to December 2007. Of all the patients, 28 were male and 22 were female, with an average age of 36.9 (range, 18 to 64) years. The symptoms, location of the cysts, imaging evaluation, surgical treatment manner, and outcome of these patients were analyzed. Results Symptoms were present in 33 of the 50 patients, and cough was the most common symptom. Thirteen patients presented with complications: hemoptysis, infected cyst, dysphagia, paralysis, and hoarseness. The locations of the cysts included the mediastinum (28 cases), pulmonary parenchyma (12 cases), hilar area (3 cases), visceral pleura (1 case), and some rare locations including the intestinal mesentery (1 case), retroperitoneum (1 case), adrenal gland (1 case), neck (2 cases), and dura matter of the cervical vertebrae (1 case). Chest X-ray was performed in 36 patients and computed tomography (CT) was performed in 41 patients. The bronchogenic cyst in CT was characterized as a round, well circumscribed, unilocular mass, with density ranging from that of water to high density (0-50 Hu). As for treatment, complete resection of the bronchogenic cyst was performed in 47 (94%) patients, subtotal resection was performed in 3 (6%) patients. Open surgery was performed in 45 (90%) patients, and thoracoscopy (video-assisted thoracic surgery) was performed in 5 (10%) paitients. Of the 12 patients with intrapulmonary cyst, 11 patients underwent lobectomy and 1 patient underwent wedge resection. Postoperative sequelae occurred in 2 patients, 1 with persistent air leakage and 1 with hoarseness. All patients were proved with bronchogenic cyst pathologically. The average follow-up period was 6.5 years (range, 4 months to 10 years), and no late sequelae or recurrence of the cyst occurred

    AIM: To analyze the clinical and endoscopic features of Chinese patients with reflux esophagitis (RE).METHODS: A total of 1405 RE patients were analyzed retrospectively. Data on gender, age, presence/absence of H pylori infection and associated esophageal hiatal hernia were collected. Esophagitis was divided into different grades according to Los Angeles Classification.RESULTS: Of 18823 patients, 1405 were diagnosed as RE. The ratio of male to female patients was 1.75:1 (P < 0.01). The mean age of male and female patients was significantly different (P = 0.01). The peak age at onset of the disease was 40-60 years. According to Los Angeles Classification, there were significant differences in the age of patients with grades A and B compared to patients with grades C and D (P < 0.01). Two hundred and seventy-seven patients were infected with H pylori, the infection rate was low (P < 0.01). Complication of esophageal hiatal hernia was found to be significantly associated with the severity of esophagitis and age in 195 patients (P < 0.01). Esophageal mucosa damages were mainly located at the right esophageal wall.CONCLUSION: The peak age of onset of RE is 40-60 years and higher in males than in females. The mean age of onset of RE is lower in males than in females. The infection rate of H pylori is significantly decreased in patients with esophagitis. Old age and esophageal hiatal hernia are associated with more severe esophagitis. Right esophageal mucosal damage can occur more often in RE patients.

    The clinical presentation and radiological features were analyzed in 30 cases of syringomyelia associated with Chiari malformation. None of the patients had spinal dysraphism. The age on admission ranged from 6 to 59 years with a mean of 27 years. Syringomyelia was diagnosed by CT myelography and or MRI from 1982 to 1988. The initial symptoms were skeletal abnormality (43%) such as scolisis (12 cases) or pescavus (one case), unilateral pain or numbness (40%) and unilateral motor weakness (17%). Frequently seen signs on admission were sensory deficit (100%), scoliosis (57%), muscle weakness (57%), muscle atrophy (37%) and lower cranial nerve palsy (40%). The neurological findings were asymmetrical in all patients. The characteristic neurological findings in the cases presenting under 20 years of age were unilateral sensory and motor deficits (61%) with decreased or absent deep tendon reflex on the same side. The localization of the syrinx in axial section varied according to the level even in the same case. In 15 cases with unilateral sensory disturbance or unilateral sensory and motor deficit, the syrinx was located in the region corresponding to the posterolateral portion on the same side as that of sensory disturbance in the cervical or thoracic level. On the other hand, in 15 cases with bilateral sensory and motor deficit, the syrinx was located in the central portion and extended into the posterolateral portion of the more affected side. The authors think that the syrinx which originates from the unilateral posterolateral portion, extends to involve the gray matter around the central canal and the posterolateral portion of the other side with progression of the syrinx to cause bilateral disturbance. As a result, unilateral neurological symptoms also become bilateral with progression of the syrinx. (author).

    Full Text Available Arsenicosis is a multisystem disorder, with virtually no system spared from its vicious claw; though its predominant manifestations are linked to cutaneous involvement. Cutaneous effects take the form of pigmentary changes, hyperkeratosis, and skin cancers (Bowen′s disease, squamous cell carcinoma, and basal cell epithelioma. Peripheral vascular disease (blackfoot disease, hypertension, ischemic heart disease, noncirrhotic portal hypertension, hepatomegaly, peripheral neuropathy, respiratory and renal involvement, bad obstetrical outcome, hematological disturbances, and diabetes mellitus are among the other clinical features linked to arsenic toxicity. The effects are mediated principally by the trivalent form of arsenic (arsenite, which by its ability to bind with sulfhydryl groups present in various essential compounds leads to inactivation and derangement of body function. Though the toxicities are mostly linked to the trivalent state, arsenic is consumed mainly in its pentavalent form (arsenate, and reduction of arsenate to arsenite is mediated through glutathione. Body attempts to detoxify the agent via repeated oxidative methylation and reduction reaction, leading to the generation of methylated metabolites, which are excreted in the urine. Understandably the detoxification/bio-inactivation process is not a complete defense against the vicious metalloid, and it can cause chromosomal aberration, impairment of DNA repair process, alteration in the activity of tumor suppressor gene, etc., leading to genotoxicity and carcinogenicity. Arsenic causes apoptosis via free radical generation, and the cutaneous toxicity is linked to its effect on various cytokines (e.g., IL-8, TGF-β, TNF-α, GM-CSF, growth factors, and transcription factors. Increased expression of cytokeratins, keratin-16 (marker for hyperproliferation and keratin-8 and -18 (marker for less differentiated epithelial cells, can be related to the histopathological findings of

    We report a clinical and neuroradiological description of a severe case of Wernicke's encephalopathy in a surgical patient. After colonic surgery for neoplasm, he was treated for a long time with high glucose concentration total parenteral nutrition. In the early post-operative period, the patient showed severe encephalopathy with ataxia, ophthalmoplegia and consciousness disorders. We used magnetic resonance imaging (MRI) to confirm the clinical suspicion of Wernicke's encephalopathy. The radiological feature showed hyperintense lesions which were symmetrically distributed along the bulbo-pontine tegmentum, the tectum of the mid-brain, the periacqueductal grey substance, the hypothalamus and the medial periventricular parts of the thalamus. This progressed to typical Wernicke-Korsakoff syndrome with ataxia and memory and cognitive defects. Thiamine deficiency is a re-emerging problem in non-alcoholic patients and it may develop in surgical patients with risk factors such as malnutrition, prolonged vomiting and long-term high glucose concentration parenteral nutrition.

    Callosal anomalies are frequently associated with other central nervous system (CNS) and/or somatic anomalies. We retrospectively analyzed the clinical features of corpus callosal agenesis/hypoplasia accompanying other CNS and/or somatic anomalies. We reviewed the imaging and clinical information of patients who underwent brain magnetic resonance imaging in our hospital, between 2005 and 2012. Callosal anomalies were isolated in 13 patients, accompanied by other CNS anomalies in 10 patients, associated with only non-CNS somatic anomalies in four patients, and with both CNS and non-CNS abnormalities in four patients. Out of 31 patients, four developed normally, without impairments in motor or cognitive functions. Five of nine patients with cerebral palsy were accompanied by other CNS and/or somatic anomalies, and showed worse Gross Motor Function Classification System scores, compared with the other four patients with isolated callosal anomaly. In addition, patients with other CNS anomalies also had a higher seizure risk.

    Purpose Thoracic ultrasound (TUS) has been proposed as an easy-option replacement for chest X-ray (CXR) in emergency diagnosis of pneumonia, pleural effusion, and pneumothorax. We investigated CXR unforeseen diagnosis, subsequently investigated by TUS, considering its usefulness in clinical risk assessment and management and also assessing the sustainability of telementoring. Patients and methods This observational report includes a period of 6 months with proactive concurrent adjunctive TUS diagnosis telementoring, which was done using freely available smartphone applications for transfer of images and movies. Results Three hundred and seventy emergency TUS scans (excluding trauma patients) were performed and telementored. In 310 cases, no significant chest pathology was detected either by CXR, TUS, or the subsequent work-up; in 24 patients, there was full concordance between TUS and CXR (ten isolated pleural effusion; eleven pleural effusion with lung consolidations; and three lung consolidation without pleural effusion); in ten patients with lung consolidations, abnormalities identified by CXR were not detected by TUS. In 26 patients, only TUS diagnosis criteria of disease were present: in 19 patients, CXR was not diagnostic, ie, substantially negative, but TUS detected these conditions correctly, and these were later confirmed by computed tomography (CT). In seven patients, even if chest disease was identified by CXR, such diagnoses were significantly modified by ultrasound, and CT confirmed that TUS was more appropriate. The overall respective individual performances of CXR and TUS for the diagnosis of a pleural–pulmonary disease in emergency are good, with accuracy >95%. Conclusion About 20% of pneumonia cases were detectable only by CXR and 20% only by TUS and not by CXR; ie, about 40% of patients may have been misdiagnosed if, by chance, only one of the two tools had been used. The concurrent use of TUS and CXR increases the overall sensitivity and

    Background Refractory anemia with ring sideroblasts associated with marked thrombocytosis was proposed as a provisional entity in the 2001 World Health Organization classification of myeloid neoplasms and also in the 2008 version, but its existence as a single entity is contested. We wish to define the clinical features of this rare myelodysplastic/myeloproliferative neoplasm and to compare its clinical outcome with that of refractory anemia with ring sideroblasts and essential thrombocythemia. Design and Methods We conducted a collaborative retrospective study across Europe. Our database included 200 patients diagnosed with refractory anemia with ring sideroblasts and marked thrombocytosis. For each of these patients, each patient diagnosed with refractory anemia with ring sideroblasts was matched for age and sex. At the same time, a cohort of 454 patients with essential thrombocythemia was used to compare outcomes of the two diseases. Results In patients with refractory anemia with ring sideroblasts and marked thrombocytosis, depending on the Janus Kinase 2 V617F mutational status (positive or negative) or platelet threshold (over or below 600×109/L), no difference in survival was noted. However, these patients had shorter overall survival and leukemia-free survival with a lower risk of thrombotic complications than did patients with essential thrombocythemia (P<0.001) but better survival (P<0.001) and a higher risk of thrombosis (P=0.039) than patients with refractory anemia with ring sideroblasts. Conclusions The clinical course of refractory anemia with ring sideroblasts and marked thrombocytosis is better than that of refractory anemia with ring sideroblasts and worse than that of essential thrombocythemia. The higher risk of thrombotic events in this disorder suggests that anti-platelet therapy might be considered in this subset of patients. From a clinical point of view, it appears to be important to consider refractory anemia with ring sideroblasts and

    Thymoma is a disease with malignant potential, which has a recurrence rate after complete resection ranging from 5 to 50 %. Multiple studies on the risk factors, treatment or prognosis have been reported. Many of them are controversial, however. In this review, we summarized some accepted risk factors, means of diagnosis and different treatments of recurrent thymoma. The risk factors of recurrent thymoma haven't been well-studied, and its management remains controversial. We reviewed the literatures and found some key points which should be noticed during the surgery of initial thymoma. Although reoperation should be taken into account preferentially, multimodal treatments are also available. The prognosis are also been discussed.

    Full Text Available Asthma is the most common chronic disease of childhood. It is known that asthma prevalence has increased significantly especially in children in last 20 years. To stop this increase in asthma, causes and prevention measures should be known better. For the management of the illness, control of environmental and trigger factors causing asthma attack are extremely important. Asthmatic children and family should be informed by health staff about changes in their life and measures to prevent the attacks. Through this information asthmatic children and their families can be supported for a better quality of life. [TAF Prev Med Bull 2010; 9(1.000: 79-86

    Full Text Available BACKGROUND: Severe malaria (SM is a major cause of death in sub-Saharan Africa. Identification of both specific and sensitive clinical features to predict death is needed to improve clinical management. METHODS: A 13-year observational study was conducted from 1997 through 2009 of 2,901 children with SM enrolled at the Royal Victoria Teaching Hospital in The Gambia to identify sensitive and specific predictors of poor outcome in Gambian children with severe malaria between the ages 4 months to 14 years. We have measured the sensitivity and specificity of clinical features that predict death or development of neurological sequelae. FINDINGS: Impaired consciousness (odds ratio {OR} 4.4 [95% confidence interval {CI}, 2.7-7.3], respiratory distress (OR 2.4 [95%CI, 1.7-3.2], hypoglycemia (OR 1.7 [95%CI, 1.2-2.3], jaundice (OR 1.9 [95%CI, 1.2-2.9] and renal failure (OR 11.1 [95%CI, 3.3-36.5] were independently associated with death in children with SM. The clinical features that showed the highest sensitivity and specificity to predict death were respiratory distress (area under the curve 0.63 [95%CI, 0.60-0.65] and impaired consciousness (AUC 0.61[95%CI, 0.59-0.63], which were comparable to the ability of hyperlactatemia (blood lactate>5 mM to predict death (AUC 0.64 [95%CI, 0.55-0.72]. A Blantyre coma score (BCS of 2 or less had a sensitivity of 74% and specificity of 67% to predict death (AUC 0.70 [95% C.I. 0.68-0.72], and sensitivity and specificity of 74% and 69%, respectively to predict development of neurological sequelae (AUC 0.72 [95% CI, 0.67-0.76].The specificity of this BCS threshold to identify children at risk of dying improved in children less than 3 years of age (AUC 0.74, [95% C.I 0.71-0.76]. CONCLUSION: The BCS is a quantitative predictor of death. A BCS of 2 or less is the most sensitive and specific clinical feature to predict death or development of neurological sequelae in children with SM.

    BACKGROUND: Spinal muscular atrophy (SMA) is a kind of degenerative disease of nervous system. There are 4 types in clinic, especially types Ⅰ, Ⅱ and Ⅲ are common, and the researches on those 3 types are relative mature. Type Ⅳ is a kind of adult spinal muscular atrophy (ASMA), which has low incidence rate and is often misdiagnosed as amyotrophic lateral sclerosis, muscular dystrophy, cervical syndrome, or others.OBJECTIVE: To observe the clinical features of 46 ASMA patients and analyze the relationship between course and activity of daily living.DESIGN: Case analysis.SETTING: Departments of Neurology of the 81 Hospital of Chinese PLA, the Second Affiliated Hospital of Nanjing Medical College and General Hospital of Nanjing Military Area Command of Chinese PLA.PARTICIPANTS: A total of 46 ASMA patients were selected from the Departments of Neurology of the 81Hospital of Chinese PLA, the Second Affiliated Hospital of Nanjing Medical College and General Hospital of Nanjing Military Area Command of Chinese PLA between April 1998 and January 2002. All patients were consentient. Among 46 cases, there were 37 males and 9 females with the mean age of 42 years. The patients' courses in all ranged from 6 months to 23 years, concretely, courses of 37 cases were less than or equal to 5 years, and those of 9 cases were more than or equal to 6 years.METHODS : ① All the 46 ASMA patients were asked to check blood sedimentation, anti O, serum creatinine,creatine, blood creatine phosphokinase (CPK) and muscular biopsy as early as possible. ② X-ray was used to measure plain film of cervical vertebra borderline film of cranium and neck at proximal end of upper limb of 25 cases and plain film of abdominal vertebra at proximal end of lower limb of 17 cases.③ Cerebrospinal fluid of lumbar puncture was checked on 42 cases, for routine examination, biochemical examination, and immunoglobulin examination.

    Objective To identify features of clinical decision support systems critical for improving clinical practice. Design Systematic review of randomised controlled trials. Data sources Literature searches via Medline, CINAHL, and the Cochrane Controlled Trials Register up to 2003; and searches of reference lists of included studies and relevant reviews. Study selection Studies had to evaluate the ability of decision support systems to improve clinical practice. Data extraction Studies were assessed for statistically and clinically significant improvement in clinical practice and for the presence of 15 decision support system features whose importance had been repeatedly suggested in the literature. Results Seventy studies were included. Decision support systems significantly improved clinical practice in 68% of trials. Univariate analyses revealed that, for five of the system features, interventions possessing the feature were significantly more likely to improve clinical practice than interventions lacking the feature. Multiple logistic regression analysis identified four features as independent predictors of improved clinical practice: automatic provision of decision support as part of clinician workflow (P < 0.00001), provision of recommendations rather than just assessments (P = 0.0187), provision of decision support at the time and location of decision making (P = 0.0263), and computer based decision support (P = 0.0294). Of 32 systems possessing all four features, 30 (94%) significantly improved clinical practice. Furthermore, direct experimental justification was found for providing periodic performance feedback, sharing recommendations with patients, and requesting documentation of reasons for not following recommendations. Conclusions Several features were closely correlated with decision support systems' ability to improve patient care significantly. Clinicians and other stakeholders should implement clinical decision support systems that incorporate these

  19. Clinical features of bacterial vaginosis in a murine model of vaginal infection with Gardnerella vaginalis.

    Nicole M Gilbert

    Full Text Available Bacterial vaginosis (BV is a dysbiosis of the vaginal flora characterized by a shift from a Lactobacillus-dominant environment to a polymicrobial mixture including Actinobacteria and gram-negative bacilli. BV is a common vaginal condition in women and is associated with increased risk of sexually transmitted infection and adverse pregnancy outcomes such as preterm birth. Gardnerella vaginalis is one of the most frequently isolated bacterial species in BV. However, there has been much debate in the literature concerning the contribution of G. vaginalis to the etiology of BV, since it is also present in a significant proportion of healthy women. Here we present a new murine vaginal infection model with a clinical isolate of G. vaginalis. Our data demonstrate that this model displays key features used clinically to diagnose BV, including the presence of sialidase activity and exfoliated epithelial cells with adherent bacteria (reminiscent of clue cells. G. vaginalis was capable of ascending uterine infection, which correlated with the degree of vaginal infection and level of vaginal sialidase activity. The host response to G. vaginalis infection was characterized by robust vaginal epithelial cell exfoliation in the absence of histological inflammation. Our analyses of clinical specimens from women with BV revealed a measureable epithelial exfoliation response compared to women with normal flora, a phenotype that, to our knowledge, is measured here for the first time. The results of this study demonstrate that G. vaginalis is sufficient to cause BV phenotypes and suggest that this organism may contribute to BV etiology and associated complications. This is the first time vaginal infection by a BV associated bacterium in an animal has been shown to parallel the human disease with regard to clinical diagnostic features. Future studies with this model should facilitate investigation of important questions regarding BV etiology, pathogenesis and

    Objective To assess the differences in incidence, clinical features, current treatment strategies and outcome in patients with type-2vs. type-1 acute myocardial infarction (AMI).Methods We included 824 consecutive patients with a diagnosis of type-1 or type-2 AMI. Dur-ing index hospitalization, clinical features and treatment strategies were collected in detail. At 1-year follow-up, mortality, stroke, non-fatal myocardial infarction and major bleeding were recorded.ResultsType-1 AMI was present in 707 (86%) of the cases while 117 (14%) were classified as type-2. Patients with type-2 AMI were more frequently female and had higher co-morbidities such as diabetes, previous non-ST segment elevation acute coronary syndromes, impaired renal function, anaemia, atrial fibrillation and malignancy. However, preserved left ventricular ejection fraction and normal coronary arteries were more frequently seen, an invasive treatment was less common, and anti-platelet medications, statins and beta-blockers were less prescribed in patients with type-2 AMI. At 1-year follow-up, type-2 AMI was associated with a higher crude mortality risk (HR: 1.75, 95% CI: 1.14-2.68;P = 0.001), but this association did not remain significant after multivariable adjustment (P = 0.785). Furthermore, we did not find type-2 AMI to be associated with other clinical outcomes.Conclusions In this real-life population, compared with type-1, type-2 AMI were predominantly women and had more co-morbidities. Invasive treatment strategies and cardioprotective medications were less used in type-2, while the 1-year clinical outcomes were similar.

    To investigate the cause analysis of clinical medication nursing risks and propose relevant nursing measures, so as to control and reduce the clinical nursing risks and reach the physical and mental safety of patients and nurses. Clinical nursing risk events with 30 cases in TCM Hospital of Zhengzhou City from June 2010 to April 2012 were underwent statistical analyses. The risk of medication error ranked the first in the direct reasons of nursing risks, accounting for a higher ratio. Moreover, the reasons of nursing risks were also involved in nonstandard operation, disease observation and other relative factors. Nurses must fully understand the relative factors of medication nursing risks, regarding the patients as their own family and always permeating the consciousness of nursing risks into the working process.

    Purpose Epilepsy is common in sub-Saharan Africa (SSA), but the clinical features and consequences are poorly characterized. Most studies are hospital-based, and few studies have compared different ecological sites in SSA. We described active convulsive epilepsy (ACE) identified in cross-sectional community-based surveys in SSA, to understand the proximate causes, features, and consequences. Methods We performed a detailed clinical and neurophysiologic description of ACE cases identified from a community survey of 584,586 people using medical history, neurologic examination, and electroencephalography (EEG) data from five sites in Africa: South Africa; Tanzania; Uganda; Kenya; and Ghana. The cases were examined by clinicians to discover risk factors, clinical features, and consequences of epilepsy. We used logistic regression to determine the epilepsy factors associated with medical comorbidities. Key Findings Half (51%) of the 2,170 people with ACE were children and 69% of seizures began in childhood. Focal features (EEG, seizure types, and neurologic deficits) were present in 58% of ACE cases, and these varied significantly with site. Status epilepticus occurred in 25% of people with ACE. Only 36% received antiepileptic drugs (phenobarbital was the most common drug [95%]), and the proportion varied significantly with the site. Proximate causes of ACE were adverse perinatal events (11%) for onset of seizures before 18 years; and acute encephalopathy (10%) and head injury prior to seizure onset (3%). Important comorbidities were malnutrition (15%), cognitive impairment (23%), and neurologic deficits (15%). The consequences of ACE were burns (16%), head injuries (postseizure) (1%), lack of education (43%), and being unmarried (67%) or unemployed (57%) in adults, all significantly more common than in those without epilepsy. Significance There were significant differences in the comorbidities across sites. Focal features are common in ACE, suggesting identifiable and

    Analysing human gait has found considerable interest in recent computer vision research. So far, however, contributions to this topic exclusively dealt with the tasks of person identification or activity recognition. In this paper, we consider a different application for gait analysis and examine its use as a means of deducing the physical well-being of people. The proposed method is based on transforming the joint motion trajectories using wavelets to extract spatio-temporal features which are then fed as input to a vector quantiser; a self-organising map for classification of walking patterns of individuals with and without pathology. We show that our proposed algorithm is successful in extracting features that successfully discriminate between individuals with and without locomotion impairment.

    Homozygous or compound heterozygous mutations in the glucocerebrosidase gene cause Gaucher disease. Moreover, heterozygous glucocerebrosidase gene mutations represent the most common genetic risk factor for Parkinson's disease (PD) known so far. Substantia nigra (SN) hyperechogenicity, a sonographic feature thought to reflect iron accumulation, has been described in both PD and Gaucher disease patients. Here we studied how clinical, genetic, and brain sonographic findings relate to the occurrence of PD in Gaucher disease. Sixteen Gaucher disease patients, 12 PD patients, and 32 control subjects were enrolled. The glucocerebrosidase genotypes were identified by DNA sequencing. All subjects underwent transcranial ultrasound, and eight Gaucher disease patients additionally MRI for comparison with SN ultrasound findings. SN hyperechogenicity and reduced echogenicity of brainstem raphe were more frequent in Gaucher disease patients (62, 37 %) than in controls (12, 12 %; p Gaucher disease patients was unrelated to type or severity of glucocerebrosidase gene mutation, but correlated with iron-sensitive MRI-T2 hypointensity of SN pars compacta, and with age at start of enzyme replacement therapy. While none of the five Gaucher disease patients with signs of PD (definite PD, n = 4; early PD, n = 1) had severe glucocerebrosidase gene mutations known to cause neuronopathic Gaucher disease, all carried a N370S allele, previously reported to predict non-neuronopathic Gaucher disease. Hyposmia, higher non-motor symptoms score (constipation, depression, executive dysfunction), and SN hyperechogenicity were characteristic features of Gaucher disease-related PD. We conclude that the combined clinical, genetic, and transcranial sonographic assessment may improve the PD risk evaluation in Gaucher disease.

    This case was diagnosed as multiple cementoosseous dysplasia on the basis of clinical and radiological features but was diagnosed as ossifying fibroma on the basis of histopathological feature. The histopathologic features of the multiple cementoosseous dysplasia and cementoossifying fibroma have common features of cementum, fibrous network and bone. Multiple cementoosseous dysplasia is reactive lesion and shows restricted lesion size, occurred on anterior and posterior tooth of the mandible and needs no treatment except periodic follow up. But Cementoossifying fibroma is the true neoplasm and grows continuously and needs surgical removal. The final diagnosis of the multiple cementoosseous dysplasia requires good correlation of the clinical histopathological, and radiological features.

  12. Feature Selection for Bayesian Evaluation of Trauma Death Risk

    CERN Document Server

    Jakaite, L

    2008-01-01

    In the last year more than 70,000 people have been brought to the UK hospitals with serious injuries. Each time a clinician has to urgently take a patient through a screening procedure to make a reliable decision on the trauma treatment. Typically, such procedure comprises around 20 tests; however the condition of a trauma patient remains very difficult to be tested properly. What happens if these tests are ambiguously interpreted, and information about the severity of the injury will come misleading? The mistake in a decision can be fatal: using a mild treatment can put a patient at risk of dying from posttraumatic shock, while using an overtreatment can also cause death. How can we reduce the risk of the death caused by unreliable decisions? It has been shown that probabilistic reasoning, based on the Bayesian methodology of averaging over decision models, allows clinicians to evaluate the uncertainty in decision making. Based on this methodology, in this paper we aim at selecting the most important screeni...

    Full Text Available Leprosy is a chronic disease caused by Mycobacterium leprae, highly incapacitating, and with systemic involvement in some cases. Renal involvement has been reported in all forms of the disease, and it is more frequent in multibacillary forms. The clinical presentation is variable and is determined by the host immunologic system reaction to the bacilli. During the course of the disease there are the so called reactional states, in which the immune system reacts against the bacilli, exacerbating the clinical manifestations. Different renal lesions have been described in leprosy, including acute and chronic glomerulonephritis, interstitial nephritis, secondary amyloidosis and pyelonephritis. The exact mechanism that leads to glomerulonephritis in leprosy is not completely understood. Leprosy treatment includes rifampicin, dapsone and clofazimine. Prednisone and non-steroidal anti-inflammatory drugs may be used to control acute immunological episodes.

    1988-01-01

    Three hundred and fifteen patients with anterior uveitis and juvenile chronic arthritis were reviewed in order to determine the incidence, visual prognosis, and the clinical characteristics of the intraocular inflammation. The overall incidence of uveitis was 20%. Approximately 25% of patients had relatively mild and/or transient involvement and an excellent visual prognosis. In 50% the uveitis was more severe but could be controlled with topical medication. In the remaining 25% the visual prognosis was poor due to the intractable nature of the uveitis and the subsequent development of vision-threatening complications. The majority of patients (74%) were under the age of 8 years when the uveitis was first diagnosed. Clinically, the intraocular inflammation was most frequently an asymptomatic, chronic, non-granulomatous, iridocyclitis which was bilateral in 71% of cases. Other ocular lesions, which were rare, included keratoconjunctivitis sicca and corneal melting.

    Full Text Available Mild hand, foot and mouth disease (HFMD is at a critical stage owing to its ease of communicability and a higher risk of developing severe complications and death. Clinical diagnosis of mild HFMD was made by the presenting symptoms and signs (symptoms in brief alone. We aim to evaluate the frequencies of symptoms in a retrospective case series study.We collected epidemiological, demographic, clinical, and laboratory data from outpatient and inpatient settings on the clinical data warehouse system. We principally described the frequencies of symptoms of mild HFMD. Correlations between symptoms with laboratory-confirmed cases were then analyzed.The clinical data warehouse system included 3649 probable cases, between 2010 and 2012, of which 956 (26.20% were laboratory confirmed. The peak incidence was identified in children 2 years of age. A total of 370 of the 956 laboratory confirmed cases (38.70% were associated with enterovirus 71 (EV71. Logistic regression analysis adjusted for geographical variables, age, sex, month of onset, and time from onset to diagnosis showed that the clinical features constipation (P<0.0001; adjusted OR, 95%CI (2.99, 2.28-3.91, and blisters (P<0.0001; adjusted OR, 95%CI (2.16, 1.82-2.56 were positively correlated with the confirmed cases.This is the largest case series study, including all the guideline-mentioned symptoms of mild HFMD. Our findings suggest that blisters and constipation should be considered as potential warning signs while front-line clinicians manage surges of children diagnosed with mild HFMD during a pandemic.

    One of the sequelae of chronic alcohol abuse is malnutrition. Importantly, a deficiency in thiamine (vitamin B(1)) can result in the acute, potentially reversible neurological disorder Wernicke encephalopathy (WE). When WE is recognized, thiamine treatment can elicit a rapid clinical recovery. If WE is left untreated, however, patients can develop Korsakoff syndrome (KS), a severe neurological disorder characterized by anterograde amnesia. Alcohol-related brain damage (ARBD) describes the effects of chronic alcohol consumption on human brain structure and function in the absence of more discrete and well-characterized neurological concomitants of alcoholism such as WE and KS. Through knowledge of both the well-described changes in brain structure and function that are evident in alcohol-related disorders such as WE and KS and the clinical outcomes associated with these changes, researchers have begun to gain a better understanding of ARBD. This Review examines ARBD from the perspective of WE and KS, exploring the clinical presentations, postmortem brain pathology, in vivo MRI findings and potential molecular mechanisms associated with these conditions. An awareness of the consequences of chronic alcohol consumption on human behavior and brain structure can enable clinicians to improve detection and treatment of ARBD.

    The clinical manifestations associated with H5N1 infection in humans range from asymptomatic infection to mild upper respiratory illness, severe pneumonia, and multiple organ failure. The ratio of symptomatic cases to asymptomatic cases is not known, because it is not possible to precisely define the number of asymptomatic cases. A total of 97 cases suffering from avian flu were suspected based on history taking, demographic data, clinical manifestations, laboratory and radiological investigations. The followings were done for all cases; complete blood picture (differential leucocytic count), coagulation profile, renal and liver function tests. H5N1 influenza virus was diagnosed thorough PCR technique. Changes in arterial blood gases and repeated chest X-rays were reported frequently. All patients were given specific antiviral therapy (oseltamivir). The study described the clinical picture and laboratory results of 81 confirmed avian influenza human cases in an Egyptian hospital (Abassia chest hospital), and reviewed the avian influenza current situation covering from March 2006 to June 2009 with very high pick in the first half of 2009. The significant apparent symptoms were fever as initial and main symptom (93.75%), followed by shortness of breathing (73%), cough (66.6%), muscle & joint pain (60%) and sore throat (40%).

    Sarcoidosis is a chronic multisystemic granulomatous disease of unknown etiology, characterized by the formation of noncaseating granulomas in the involved organs. Cutaneous involvement is about 25% with different clinical expressions, the lichenoid pattern being one of the rarest types of cutaneous sarcoidosis. Lichenoid sarcoidosis clinically manifests with multiple scale papules involving extensive skin areas, especially the trunk, limbs, and face mimicking a lichen planus. Although diverse histologic patterns have been previously related, a lichenoid granulomatous infiltrate involving the dermo-epidermal junction has never been reported in lichenoid sarcoidosis. We report a case of a 43-year-old woman presenting with skin-colored pruritic papules, slightly scaling in trunk, extremities, and ears. These symptoms condition continued to expand and worsen for several years. The patient was otherwise in good health with no lymphadenopathies. Histopathologic examination of a skin biopsy showed an upper dermal granulomatous infiltrate of epithelioid cells, without necrosis, distributed in a lichenoid pattern with many cytoid bodies. We consider this may be the first case presenting a characteristic microscopic granulomatous lichen-like pattern in the setting of a clinically lichenoid type of sarcoidosis.

    Full Text Available Aim: Macroprolactin is a high-molecular-weight form of prolactin. It has been suggested that macroprolactin has no clinical importance because of its decreased or limited bioactivity. Although screening for macroprolactinemia is recommended especially in patients with idiopathic hyperprolactinemia; recent studies reported that patients with macroprolactinemia may have some hyperprolactinemia symptoms. Currently, the causes of the symptoms as well as the treatment and follow-up of this group of patients are not clear. In our study, we aimed to retrospectively evaluate and compare the clinical characteristics and gonadal hormone levels of patients with macroprolactinemia and hyperprolactinemia.Materials and Methods: Forty patients with macroprolactinemia and 15 patients with hyperprolactinemia who referred to Obstetrics and Gynecology Hospital were examined.Results: We observed that the patients with macroprolactinemia had similar menstrual disturbances (oligomenorrhea/amenorrhea to the patients with hyperprolactinemia. There was no statistically significant difference between the two groups with respect to FSH, LH and estradiol levels. The frequencies of galactorrhea (p=0.002, headache (p=0.04 and positive radiological finding (p=0.001 were higher in patients with hyperprolactinemia. Infertility rate was found to be increased in women with macroprolactinemia (p=0.02.Conclusion: Patients with macroprolactinemia may have very similar clinic symptoms to those with hyperprolactinemia. Therefore, macroprolactin levels should be measured regardless of the symptoms of hyperprolactinemia in patients with elevated prolactin levels. Türk Jem 2011; 15: 62-5

    ABSTRACT Objectives. To describe (i) the clinical characteristics of workers, exposed to hymenoptera stings, with an ascertained diagnosis of Hymenoptera Venom Allergy (HVA), (ii) the specific role of occupational exposure, (iii) the effect of Venom Immunotherapy (VIT) in reducing the severity of allergic episodes in workers exposed to repeated stings of hymenoptera, and (iv) the management of the occupational consequences caused by allergic reactions due to hymenoptera stings. Methods. Between 2000 and 2013 an observational study, including patients referred to the regional reference hospital of Liguria, Italy, with an ascertained diagnosis of HVA and treated with VIT, was performed. A structured questionnaire was administered to all patients to investigate the occupational features of allergic reactions. These were graded according to standard systems in patients at the first episode, and after re-stings, during VIT. Results. One-hundred and 8four out of the 202 patients referred had a complete data set. In 32 (17.4%) patients, the allergic reaction occurred during work activities performed outdoor. Of these, 31.2% previously stung by hymenoptera at work, and receiving VIT, were re-stung during occupational activity. The grades of reaction developed under VIT treatment resulted clinically less severe than of those occurred at the first sting (p-value = 0.031). Conclusion. Our findings confirmed the clinical relevance of HVA, and described its occupational features in outdoor workers with sensitization, stressing the importance of an early identification and proper management of the professional categories recognized at high risk of hymenoptera stings. The Occupational Physician should be supported by other specialists to recommend appropriate diagnostic procedures and the prescription of VIT, which resulted an effective treatment for the prevention of episodes of severe reactions in workers with a proven HVA.

    Full Text Available BACKGROUND: Morbidity associated with primary headache disorders is a major public health problem with an overall prevalence of 46%. Tension-type headache and migraine are the two most prevalent causes. However, headache has not been sufficiently studied as a cause of morbidity in the developing world. Literature on prevalence and classification of these disorders in South Asia is scarce. The aim of this study is to describe the classification and clinical features of headache patients who seek medical advice in Pakistan. METHODS AND RESULTS: Medical records of 255 consecutive patients who presented to a headache clinic at a tertiary care hospital were reviewed. Demographic details, onset and lifetime duration of illness, pattern of headache, associated features and family history were recorded. International Classification of Headache Disorders version 2 was applied. 66% of all patients were women and 81% of them were between 16 and 49 years of age. Migraine was the most common disorder (206 patients followed by tension-type headache (58 patients, medication-overuse headache (6 patients and cluster headache (4 patients. Chronic daily headache was seen in 99 patients. Patients with tension-type headache suffered from more frequent episodes of headache than patients with migraine (p<0.001. Duration of each headache episode was higher in women with menstrually related migraine (p = 0.015. Median age at presentation and at onset was lower in patients with migraine who reported a first-degree family history of the disease (p = 0.003 and p<0.001 respectively. CONCLUSIONS/SIGNIFICANCE: Patients who seek medical advice for headache in Pakistan are usually in their most productive ages. Migraine and tension-type headache are the most common clinical presentations of headache. Onset of migraine is earlier in patients with first-degree family history. Menstrually related migraine affects women with headache episodes of longer duration than other patients

    Sleep is disrupted in most patients hospitalized in the intensive care unit and the disturbances are even more profound in patients impacted by epilepsy. Nocturnal seizures must be differentiated from other common nocturnal events, such as delirium, parasomnias, and sedation. Many antiepileptic drugs produce undesirable side effects on sleep architecture that may further predispose patients to insomnia during the night and excessive sedation and hypersomnolence during the day. Failure to recognize, correctly diagnose, and adequately manage these disturbances may lead to more prolonged hospitalization, increased risk for nosocomial infections, poorer health-related qualify of life, and greater health care financial burden.

    Full Text Available In June 2014, Suriname faced the first Chikungunya outbreak. Since international reports mostly focus on hospitalized patients, the least affected group, a study was conducted to describe clinical characteristics of mainly outpatients including children. In addition, the cumulative incidence of this first epidemic was investigated.During August and September 2014, clinically suspected Chikungunya cases were included in a prospective follow-up study. Blood specimens were collected and tested for viral RNA presence. Detailed clinical information was gathered through multiple telephone surveys until day 180. In addition, a three stage household-based cluster with a cross-sectional design was conducted in October, December 2014 and March 2015 to assess the cumulative incidence.Sixty-eight percent of symptomatic patients tested positive for Chikungunya virus (CHIKV. Arthralgia and pain in the fingers were distinctive for viremic CHIKV infected patients. Viremic CHIKV infected children (≤12 years characteristically displayed headache and vomiting, while arthralgia was less common at onset. The disease was cleared within seven days by 20% of the patients, while 22% of the viremic CHIKV infected patients, mostly women and elderly reported persistent arthralgia at day 180. The extrapolated cumulative CHIKV incidence in Paramaribo was 249 cases per 1000 persons, based on CHIKV self-reported cases in 53.1% of the households and 90.4% IgG detected in a subset of self-reported CHIKV+ persons. CHIKV peaked in the dry season and a drastic decrease in CHIKV patients coincided with a governmental campaign to reduce mosquito breeding sites.This study revealed that persistent arthralgia was a concern, but occurred less frequently in an outpatient setting. The data support a less severe pathological outcome for Caribbean CHIKV infections. This study augments incidence data available for first outbreaks in the region and showed that actions undertaken at the

    Full Text Available Objective: To assess the clinical characteristics of gout and its diagnostic approach in a group of Italian patients. Methods: In a retrospective analysis, we evaluated 72 consecutive gouty patients examined in the years 2000-2007.We recorded demographic data, family history, comorbidities and disease characteristics (seasonality of the attacks, joints affected, serum uric acid concentration, and treatment. Result: 63/72 (87.5% patients were men and 9 women, with mean age 61.9±13.7 years. 8/72 (11.1% patients reported a familial history of gout. The first attack occurred mainly in the months of June, July and December. The first metatarsophalangeal joint was affected in 59.7% of patients and the hand in 25%. Treatment changed over the follow- up period, with a decreased use of NSAIDs (p<0.0001 and an increased use of colchicine (p=0.015 and allopurinol (p<0.0001. In 9 (12.5% patients, joint aspiration was performed and monosodium urate crystals were found in synovial fluid or tophi. 42/72 (58.3% patients fulfilled a minimum of 6 clinical criteria of the American College of Rheumatology, necessary for gout diagnosis. 47/72 (65.3% patients, met the EULAR recommendations and had an 82% probability of being affected by gout. Conclusions: The diagnosis of gout is not always easy because of its changing clinical spectrum. Identification of MSU crystals in joint aspirates was obtained only in a minority of patients. In this setting the diagnosis with gout was often based on the observation of an acute intermittent monoarthritis involving mainly the first metatarsophlangeal joint, associated with hyperuricaemia and responsive to colchicine.

Methods: In this retrospective study, the data from 64 children with psoriasis admitted at the our dermatology clinic between January 2007 and January 2011 were included whose data were fully. Results: Of the patients, 37 (57.8% were boys and 27 (42.2% were girls. Mean age of the children was 10.08 ±3.98 years (3-16. In 10 (15% cases, a positive family history was detected. The most frequent localizations at onset were trunk (46.9%, scalp (28.1%, knee-elbow (10.9% and extremities (7.9%, respectively. The most commonly seen clinical types were plaque (68.8%, guttate (20.3%, palmoplantar (9.4%, pustular (1.6%, respectively. Nine children had nail involvement. Out of all patients, 21.9% had upper respiratory tract infections and 9.4% had emotional stres. Four cases were diagnosed with depression. Of the cases, two cases were on non-steroid anti-inflammatory medication, and 4 of them were on antibiotics. Systemic treatments were given to 21.9% of the cases besides topical treatments. Conclusion: The epidemiological studies of psoriasis during childhood period for different countries have been reported. In this study, the ratio shows differences when compared to those previous studies. There are few epidemiologic studies for Turkey. We believe that further epidemiological studies including large number of patients' groups will contribute the diagnosis and treatment of the disease.

    Full Text Available Background: The transition from fetal to neonatal life during birth is difficult for all babies. We aim to analyze the demography, clinical presentation, causes, and outcome of neurologically distressed newborns. Materials and Methods: We reviewed a total of 615 newborns files admitted with life threatening condition. Amongst them, 453 had presented neurological distress syndrome. Only cases with severe neurological impairment (Apgar Score System [ASS] ≤6 with no other associated injury were included in the study group. The study covered a period from January to December 2011 and located in pediatric intensive care unit. The information regarding clinical presentation, condition of birth, causes of distress, and outcome were analyzed. Neonate examination had been conducted by neonatologist and pediatric neurologist. Results: The sample included 272/453 (60.04% males and 181/453 (39.96% females. Newborns were aged from 1 to 14 days. The incidence of neurological distress amongst all admissions was 453/615 (73.65%. Clinical signs were weakness of primary reflexes (86.70%, non reactivity (78.19%, flaccid muscle tone (59.49% and impaired consciousness (32.29%. On Apgar score, 73 (20.68% had a score from 0 to 3; 234 (66.29% had a score 4-6 in the first minute of life. A total of 307 (86.97% newborns had been resuscitated at birth during the first five minutes. Death rate was 35.69%. Asphyxia (51.27% and neonatal infection (43.34% were the most common causes of death. Conclusion: These results show that much effort remains to be done in obstetric care, resuscitation management and improvement in neonatal infection care.

    We report six patients with partial, predominantly paramedian, tegmental pontine hemorrhages. Constant clinical manifestations consisted of: ipsilateral miosis, horizontal gaze paresis, lower motor neuron facial paresis, contralateral hemisensory loss and mild and transitory hemiparesis, dysarthria and mild or no compromise of consciousness. Five out of six were hypertensive. All patients survived with mild sequelae, oculomotor disturbances being the most persistent deficit. We found in our patients that a transverse diameter of less than 17 mm, unilaterality of the injury and absence of coma were the major indicators of a favorable outcome.

    Full Text Available Background: The forearm refractures are the most common and serious injuries in the childhood. In our practice the refractures in children occur from 1.3% up to 5.2% among all fractures in children. Clinical characteristics of the refractures were highlighted insufficiently. Purpose: To study clinical signs of forearm refractures and effect of osteoreparative process. Material and methods: In the department of children's trauma of Scientific Research Institute of Traumatology and Orthopedics during the period from 2002 to 2012 from the general number of the patients 136 children with refracture of the tubular bones were revealed. With regard to the number of fractures twice refractures were in 132 patients, three times refractures found in 4 patients. From these patients 102 were boys and 34 were girls. According to structure of refracture localization the forearm refractures were on the leading place, which were observed in 109 (80.1% of patients. The refractures of the middle third forearm were noted in 82 patients, the refracture of middle upper third forearm - in 2 patients, the refracture of the lower third forearm was in 25 patients. Results: In the refractures at the second stage of regeneration (time of occurrence more than 3 months, especially at the moment of active process of the callus ossification the close of medullar canal occur and hematoma volume became significantly less than in primary fracture. At refractures hematoma at the place of fracture was more localized. At the refracture the weak pain is defined, and sometimes pain can be absent (about the reasons is said above, and the main active and passive movements in the full volume. The cases of absence of crepitation are possible in refractures. It is important that in refractures the longitudinal and impacted displacement we did not observe. In cases with painless clinical course of the refracture in the patients the active and passive movements were saved in complete volume

    Central neurocytoma (CN) is a rare, benign brain tumor often located in the lateral ventricles. CN may cause obstructive hydrocephalus and manifest as signs of increased intracranial pressure. The goal of treatment for CN is a gross total resection (GTR), which often yields excellent prognosis with a very high rate of tumor control and survival. Adjuvant radiosurgery and radiotherapy may be considered to improve tumor control when GTR cannot be achieved. Chemotherapy is also not considered a primary treatment, but has been used as a salvage therapy. The radiological features of CN are indistinguishable from those of other brain tumors; therefore, many histological markers, such as synaptophysin, can be very useful for diagnosing CNs. Furthermore, the MIB-1 Labeling Index seems to be correlated with the prognosis of CN. We also discuss oncogenes associated with these elusive tumors. Further studies may improve our ability to accurately diagnose CNs and to design the optimal treatment regimens for patients with CNs.

    The current study reports the clinical features and treatment outcome of 67 patients with acute promyelocytic leukemia (APL presented to National Cancer Institute (NCI-Cairo, in Egypt from January 2007 to January 2011. The median follow-up time was 36 months. All patients were treated with the simultaneous administration of all-trans retinoic acid (ATRA and anthracyclin. The treatment protocol was modified due to resource limitations at the NCI-Cairo by replacing of idarubicin with doxorubicin in most of the cases and the inclusion of cytarbine during the consolidation phase only in pediatric patients. All patients who achieved molecular complete remission (CRm after consolidation received two-year maintenance treatment with low dose chemotherapy composed of 6 mercaptopurine, methotrexate and intermittent ATRA courses. The median age at presentation was 29 years. There was a slight male predominance (53%.  Bleeding was the most common presenting symptom (79%. Most patients had an intermediate risk Sanz score (49% and 34% had a high risk score.  All patients achieved molecular CR at end of consolidation therapy with a median duration of 100 days. The main therapeutic complications during the induction phase were febrile neutropenia (42%, bleeding (18% and differentiation syndrome (11%. Five patients died at diagnosis due to bleeding, three died during induction chemotherapy due to febrile neutropenia (n=2 and bleeding (n=1 and one patient died during consolidation therapy due to febrile neutropenia.  The 3-year OS was 89% and relapse rate was 3%. Adapting standard AIDA treatment protocols to limited resources by reducing dose-intensity during treatment consolidation, using ATRA in the consolidation phase and alternative anthracyclin (doxorubicin may be a valid treatment option in developing countries.

    Purpose: To investigate the clinical characteristics and determine the effective surgical managements of A-pattern exotropia.Methods: Thirty-two patients with A-pattern exotropia underwent superior oblique muscle weakening procedures, medial rectus resection or (and) lateral rectus recession. Preand post-operative eye position, deviation angle, superior oblique function and binocular vision were examined and analyzed in the cases.Results: Overaction of the superior oblique muscles (31/32) and underaction of the medial rectus muscle (20/32) were presented in the cases. Postoperatively, a satisfactory ocular alignment was obtained in 28 cases (87.5%), and the A-pattern was corrected in 31 cases (96.9%). Four cases got binocular vision after surgery.Conclusions: As one of the most common forms of A and V patterns, A-pattern exotropia showed clinical characteristics of superior oblique muscle overaction and medial rectus muscle underacion, which should be the primary factors in the etiology of A-pattern exotropia, and superior oblique weakening procedures combined with horizontal surgery should be an effective approach to A-pattern exotropia treatment.

    Nontyphoid Salmonella is the most common bacterial pathogen causing gastrointestinal infection worldwide. Most nontyphoid Salmonella infection is limited to uncomplicated gastroenteritis that seldom requires antimicrobial treatment. Nevertheless, invasive infections, such as bacteremia, osteomyelitis, and meningitis, may occur and require antimicrobial therapy. Continuous genetic and genomic evolution in Salmonella leading to increased virulence and resistance to multiple drugs are of significant public health concern. Two major changes in the epidemiology of nontyphoid salmonellosis in Europe and in the USA occurred in the second half of the 20(th) century: the emergence of foodborne human infections caused by Salmonella enterica serotype Enteriditis and by multidrug-resistant strains of Salmonella enterica serotype Typhimurium. In the 21(st) century, a worsening situation is the increasing resistance to fluoroquinolones and third-generation cephalosporins in nontyphoid Salmonella. Clinical isolates showing carbapenem resistance also have been identified. Although antimicrobial therapy is usually not indicated for uncomplicated Salmonella gastroenteritis, recent studies indicated that a short-course ceftriaxone therapy (3-5 days) for patients with severe gastroenteritis would lead to a faster clinical recovery. Continuous surveillance of Salmonella in both humans and animals is mandatory. A better understanding of the mechanisms that lead to the emergence of antimicrobial resistance in Salmonella may help in the devising of better interventional strategies to reduce the spread of resistant Salmonella between humans and reservoirs along the food chain.

    Primary biliary cirrhosis (PBC), which is characterized by progressive destruction of intrahepatic bile ducts, is not a rare disease since both prevalence and incidence are increasing during the last years mainly due to the improvement of case finding strategies. The prognosis of the disease has improved due to both the recognition of earlier and indolent cases, and to the wide use of ursodeoxycholic acid (UDCA). New indicators of prognosis are available that will be useful especially for the growing number of patients with less severe disease. Most patients are asymptomatic at presentation. Pruritus may represent the most distressing symptom and, when UDCA is ineffective, cholestyramine represents the mainstay of treatment. Complications of long-standing cholestasis may be clinically relevant only in very advanced stages. Available data on the effects of UDCA on clinically relevant end points clearly indicate that the drug is able to slow but not to halt the progression of the disease while, in advanced stages, the only therapeutic option remains liver transplantation.

  6. Diagnosis and clinical features of trigemino-autonomic headaches.

    May, Arne

    2013-10-01

    Although severe short-lasting headaches are rare, they can be considered disabling conditions with a major impact on the quality of life of patients. These headaches can divided broadly in to those associated with autonomic symptoms, so called trigeminal autonomic cephalgias (TACs), and those with few or no autonomic symptoms. The TACs include cluster headache, paroxysmal hemicranias, hemicrania continua, and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms as well as short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing syndrome. In all of these syndromes, half-sided head pain and ipsilateral cranial autonomic symptoms such as lacrimation or rhinorrhea are prominent. The paroxysmal hemicranias have, unlike cluster headaches, a very robust response to indomethacin, leading to a notion of indomethacin-sensitive headaches. The diagnosis of TACs is exclusively a clinical task. Because of the fact that cluster headache is strictly half-sided, typically involves the region around the eye and temple and often starts in the upper jaw, most patients first consult a dentist or ophthalmologist. No single instrumental examination has yet been able to define, or ensure, the correct diagnosis, or differentiate idiopathic headache syndromes. It is crucial that a trained neurologist sees these patients early so that management can be optimized and unnecessary procedures can be avoided. Although TACS are, in comparison to migraine, quite rare, they are nevertheless clinically very important for the neurologist to consider as they are easy to diagnose and the treatment is very effective in most patients.

    2008-01-01

    Full Text Available Thalassemia is a type of hereditary anemia that predominantly affects individuals born in or descendents of countries bathed by the Mediterranean Sea, such as Italy and Greece. Also known as Cooley’s anemia and Mediterranean anemia, the disease causes alterations in hemoglobin formation and malformations of the cranium, long bones, maxilla and mandible. It presents two distinct clinical conditions: one severe, called “major” thalassemia, and the other mild, denominated “minor” thassalemia. Hematologic exam diagnoses the two forms of the disease. Its clinical and radiographic manifestations include hepatosplenomegalia, lymphadenopathy, augmented mandible, increase in medullary spaces, thick bone trabeculae and in lower quantity, resembling a “spider web”, displacement of the mandibular canal, with loss of detail of its superior and inferior corticals and a radiographic aspect of “hair standing on end” at the surface of the cranium. Some of these manifestations are so characteristic and capable of being observed in radiographs that they form part of the dentist’s routine. This case report discusses the alterations observed in the panoramic radiograph of a patient with thalassemia diagnosed by means of hematologic exam.

    Results: Forty one of the patients were female (57.7% and 30 of them were male (42.3%. Mean age of patients was 25+/-10,04 years; first treatment age was 27.75+/-9.19 and mean duration of untreated illness was 32.82+/-48.06 months. There was a significant difference in patients, when first treatment age and mean duration of untreated illness were examined by gender. In patients with family history of obsessive-compulsive disorder, the mean duration of untreated illness was higher. Conclusion: Obsessive compulsive disorder is a chronic disorder with significant risk factors for prognosis. [Cukurova Med J 2017; 42(1.000: 140-146

    Fuchs' uveitis is very often diagnosed with substantial delay, which is at the origin of deleterious effects such as unnecessary treatment and its consequences. The aim of this study was to analyse the type and frequency of posterior inflammatory and fluorescein angiographic signs in Fuchs' uveitis in conjunction with other clinical signs. Patients seen at the Centre for Ophthalmic Specialised Care (COS) in Lausanne and the Memorial A. de Rothschild, Clinique Générale-Beaulieu in Geneva between 1995 and 2008 with the diagnosis of Fuchs' uveitis and who had undergone a fundus fluorescein angiography (FFA) were analysed. In addition to FFA signs, the data collected included age, gender, initial and final visual acuities, clinical findings at presentation, mean diagnostic delay and ocular complications. Between 1995 and 2008, 105 patients seen in our centres in Lausanne and Geneva were diagnosed with Fuchs' uveitis. Forty of them (38.1%) had undergone at least one FFA. One patient was excluded because of a concomittant diagnosis of multiple sclerosis. In 28 of 39 patients (71.2%) diagnosis was not reached at presentation with a mean diagnosis delay of 3.67 ± 4.86 years (range: 1 month-24 years). The original erroneous diagnosis was intermediate uveitis in 16 patients (57.1%), posterior uveitis in two patients (7.1%), panuveitis in four patients (14.3%) and anterior granulomatous uveitis in six patients (21.4%). Fluorescein angiography demonstrated the presence of disc hyperfluorescence in 43/44 eyes (97.7%), sectorial peripheral retinal vascular leaking in 6/44 eyes (13.6%) and cystoid macular oedema in 4/44 eyes (9.1%), all of which were seen in eyes having undergone cataract surgery. Fuchs' uveitis was bilateral in 5/39 patients (12.8%). The most frequent clinical signs were vitritis in 42/44 eyes (95.5%), stellate keratic precipitates in 41 eyes (93.2%), posterior subcapsular opacities or cataract in 19 eyes (43.2%), and heterochromia in 19 eyes (43.2%).

    A retrospective study was conducted of the clinical records of 41 patients discharged from a hospital in Tarapoto, Peru, between August 1992 and June 1996 following treatment for Plasmodium falciparum malaria. Patients ranged in age from 18 to 65 years; 25 were male. The cases were uniformly distributed throughout the year. The duration of illness averaged 11 days. At admission, 40 patients had fever, 36 had shaking chills, 29 had headache, 21 had nausea and vomiting, 21 had hyporexia, 15 had pallor, and 13 had splenomegaly. 3 of the 16 women were pregnant. 7 patients reported a history of malaria. The admission diagnosis was malaria in 33 cases. 31 patients were treated with chloroquine; 18 were subsequently treated with pyrimethamine-sulfadoxin and 1 received doxycycline. No cases of grave illness or death occurred. The increasing presence of Plasmodium falciparum malaria in the Peruvian lowlands should promote review of the adequacy of control programs.

    The authors present the results of examination of 34 patients, aged from 18 to 30 years, with attention deficit hyperactivity disorder (ADHD) (ICD-10 item F90.0). The study has shown that inattentive type of ADHD is noted in 50%, combined type in 38.3% and hyperactivity/impulsivity type in 11.7% of patients. Adult patients with ADHD also have a high level of anxiety and asthenic disorders. This study evaluated the efficacy and safety of adaptol in dosage 1500 mg daily during 8 weeks in the treatment of this group of patients. The high efficacy (improvement in 64,7% of cases) and safety of adaptol confirmed by the data of clinical, psychological and neurophysiological studies.

    The case a twenty year old patient is reported, whose chest X-ray demonstrated cardiomegaly with a prominent pulmonary segment. The echocardiographical examination indicated a single ventricle with septal rudiments; heart catherization confirmed the diagnosis of a single ventricle of the right ventricular type with a well-sized left ventricular outlet chamber and the banding of the pulmonary artery. In addition the case of a 17 year old patient is reported, whose chest X-ray demonstrated dextrocardia. Clinical manifestations (cyanosis, elevated hemoglobin, clubbing, 3rd heart sound) as well as one- and two-dimensional echocardiography with echocontrast media confirmed the diagnosis of corrected transposition of the great arteries, pulmonary stenosis and incompetence, single ventricle and dextrocardia, a diagnosis made already 12 years ago by heart catherization.

    2004-01-01

    This article compares the performance of multiple logistic regression (MLR) with feed-forward, artificial neural network (ANN) models for the assessment of adolescent marijuana use and clinical features of dependence based on self-evaluation from recent National Household Surveys on Drug Abuse (NHSDA). The effect of training and testing the neural networks with randomly selected data was compared to data selected as a function of survey year. The technical aim of the study was to account for adolescent marijuana use and features of marijuana dependence based on experiences with alcohol and tobacco. Similarities observed in MLR and ANN model performance may indicate no major complex or nonlinear relationships in cross-sectional epidemiological data selected to model adolescent drug use and dependence in this specific application. We concluded that ANNs should be further studied in future longitudinal research, perhaps with modeling of recursive networks, allowing feedback from drug dependence to levels of marijuana use. The ANN models also have the potential to model drug use and dependence based on input parameters with no obvious direct link to drug involvement--e.g., polymorphisms associated with "openness to experience" or other personality traits hypothesized to function as distal antecedents, and could thus be implemented to identify higher risk youths using assessments indirectly related or nonlinearly associated to adolescent drug use and dependence but less sensitive to survey-related response tendencies.

    Full Text Available The research goal is to determine risk factors of periodontal disease development, psychophysiological personal types and their interrelations in clinically healthy persons. 47 first-year cadets of St.-Petersburg Military School of radio electronics have been examined. This group of respondents has been chosen by presence of such social stressor as change of place of living (97,9% cadets have arrived in St.-Petersburg from other cities and republics of the Russian Federation and strict disciplinary conditions. The research has revealed a low level of oral hygiene, cases of mild gingivitis in most respondents. The general mental state of group under study is characterized by raised level of personal anxiety and low indices of reactive anxiety. The examined group has demonstrated anxiety, tension, indecision and lowered stress stability. Clinically healthy persons are more liable to develop inflammatory and inflammatory-destructive periodontal diseases. It was possible to determine psychophysiological features correlated with physiological parameters of risk degree of periodontal diseases. It may have a great significance in defining of periodontal disease etiology and pathogenesis

    To characterize the radiological and clinicopathologic features of cystic synovial sarcoma. Seven patients with primary cystic synovial sarcoma were evaluated. Computed tomography (CT) and magnetic resonance (MR) imaging were undertaken at the first presentation. The diagnosis of synovial sarcoma was made on the basis of histological examinations followed by molecular analysis. Radiological and clinicopathologic findings were reviewed. CT showed well-defined soft tissue mass without cortical bone erosion and invasion. Calcification was seen at the periphery of the mass in three cases. T2-weighted MR images showed multilocular inhomogeneous intensity mass in all cases, five of which showed fluid-fluid levels. On gross appearance, old and/or fresh hematomas were detected in six cases. In the one remaining case, microscopic hemorrhage in the cystic lumen was proven. Four cases had poorly differentiated areas. In five cases prominent hemangiopericytomatous vasculature was observed. Histologic grade was intermediate in one tumor and high in six. One case had a history of misdiagnosis for tarsal tunnel syndrome, one for lymphadenopathy, two for sciatica and two for hematoma. All cystic synovial sarcomas demonstrated multilocularity with well-circumscribed walls and internal septae. Synovial sarcoma should be taken into consideration in patients with deeply situated multicystic mass with triple signal intensity on T2-weighted MR imaging. (orig.)

  18. A Rank Aggregation Algorithm for Ensemble of Multiple Feature Selection Techniques in Credit Risk Evaluation

    Directory of Open Access Journals (Sweden)

    Shashi Dahiya

    2016-10-01

    Full Text Available In credit risk evaluation the accuracy of a classifier is very significant for classifying the high-risk loan applicants correctly. Feature selection is one way of improving the accuracy of a classifier. It provides the classifier with important and relevant features for model development. This study uses the ensemble of multiple feature ranking techniques for feature selection of credit data. It uses five individual rank based feature selection methods. It proposes a novel rank aggregation algorithm for combining the ranks of the individual feature selection methods of the ensemble. This algorithm uses the rank order along with the rank score of the features in the ranked list of each feature selection method for rank aggregation. The ensemble of multiple feature selection techniques uses the novel rank aggregation algorithm and selects the relevant features using the 80%, 60%, 40% and 20% thresholds from the top of the aggregated ranked list for building the C4.5, MLP, C4.5 based Bagging and MLP based Bagging models. It was observed that the performance of models using the ensemble of multiple feature selection techniques is better than the performance of 5 individual rank based feature selection methods. The average performance of all the models was observed as best for the ensemble of feature selection techniques at 60% threshold. Also, the bagging based models outperformed the individual models most significantly for the 60% threshold. This increase in performance is more significant from the fact that the number of features were reduced by 40% for building the highest performing models. This reduces the data dimensions and hence the overall data size phenomenally for model building. The use of the ensemble of feature selection techniques using the novel aggregation algorithm provided more accurate models which are simpler, faster and easy to interpret.

    Nineteen adults with brain tumors have been studied with positron emission tomography utilizing FDG. Fourteen had biopsy proven cerebral malignant glioma, one each had meningioma, hemangiopericytoma, primitive neuroectodermal tumor (PNET), two had unbiopsied lesions, and one patient had an area of biopsy proven radiation necrosis. Three different patterns of glucose metabolism are observed: marked increase in metabolism at the site of the known tumor in (10 high grade gliomas and the PNET), lower than normal metabolism at the tumor (in 1 grade II glioma, 3 grade III gliomas, 2 unbiopsied low density nonenhancing lesions, and the meningioma), no abnormality (1 enhancing glioma, the hemangiopericytoma and the radiation necrosis.) The metabolic rate of the tumor or the surrounding brain did not appear to be correlated with the history of previous irradiation or chemotherapy. Decreased metabolism was frequently observed in the rest of the affected hemisphere and in the contralateral cerebellum. Tumors of high grade or with enhancing CT characteristics were more likely to show increased metabolism. Among the patients with proven gliomas, survival after PETT scan tended to be longer for those with low metabolic activity tumors than for those with highly active tumors. The authors conclude that PETT may help to predict the malignant potential of tumors, and may add useful clinical information to the CT scan.

    Full Text Available BackgroundEndogenous hyperinsulinemic hypoglycemia (EHH is characterized by an inappropriately high plasma insulin level, despite a low plasma glucose level. Most of the EHH cases are caused by insulinoma, whereas nesidioblastosis and insulin autoimmune syndrome (IAS are relatively rare.MethodsTo evaluate the relative frequencies of various causes of EHH in Korea, we retrospectively analyzed 84 patients who were diagnosed with EHH from 1998 to 2012 in a university hospital.ResultsAmong the 84 EHH patients, 74 patients (88%, five (6%, and five (6% were diagnosed with insulinoma, nesidioblastosis or IAS, respectively. The most common clinical manifestation of EHH was neuroglycopenic symptoms. Symptom duration before diagnosis was 14.5 months (range, 1 to 120 months for insulinoma, 1.0 months (range, 6 days to 7 months for nesidioblastosis, and 2.0 months (range, 1 to 12 months for IAS. One patient, who was diagnosed with nesidioblastosis in 2006, underwent distal pancreatectomy but was later determined to be positive for insulin autoantibodies. Except for one patient who was diagnosed in 2007, the remaining three patients with nesidioblastosis demonstrated severe hyperinsulinemia (157 to 2,719 µIU/mL, which suggests that these patients might have had IAS, rather than nesidioblastosis.ConclusionThe results of this study suggest that the prevalence of IAS may be higher in Korea than previously thought. Therefore, measurement of insulin autoantibody levels is warranted for EHH patients, especially in patients with very high plasma insulin levels.

    This report describes a suicide case by acute arsenic intoxication via intravenous injection. A 30-year-old woman injected arsenic As (V) (sodium arseniate disodique: Disodium Hydrogena Arsenik RP) in a successful suicide attempt. Three hours following administration, the woman developed severe digestive symptoms. She was admitted to a hospital and transferred to the intensive care unit within 12 h of the massive administration of arsenic. Despite therapeutic efforts, over the next 2 h she developed multiorgan failure and died. A postmortem examination was performed. Pulmonary edema and congestion of liver were apparent. As (V) and As (III) were determined by high performance liquid chromatography and inductively coupled plasma mass spectrometry after mineralization of samples by concentrated nitric acid. Toxicological analysis revealed high concentrations of arsenic in biological fluids as well as in organs. Histopathological examination showed a typical indication of myocarditis. These findings were in agreement with acute arsenic poisoning. The symptoms developed by this young woman (intoxication by intravenous administration) were comparable to oral intoxication. The clinical signs, survival time, and administration type are discussed in light of the literature on acute and chronic arsenic poisoning.

    Human intestinal capillariasis is a rare parasitosis that was first recognized in the Philippines in the 1960 s. Parasitosis is a life threatening disease and has been reported from Thailand, Japan, South of Taiwan (Kaoh-Siung), Korea,Tran, Egypt, Italy and Spain. Its clinical symptoms are characterized by chronic diarrhea, abdominal pain,borborygmus, marked weight loss, protein and electrolyte loss and cachexia. Capillariasis may be fatal if early treatment is not given. We reported 14 cases living in rural areas of Taiwan. Three cases had histories of travelling to Thailand. They might have been infected in Thailand while stayed there. Two cases had the diet of raw freshwater fish before. Three cases received emergency laparotomy due to peritonitis and two cases were found of enteritis cystica profunda. According to the route of transmission,freshwater and brackish-water fish may act as the intermediate host of the parasite. The most simple and convenient method of diagnosing capillariasis is stool examination. Two cases were diagnosed by histology.Mebendazole or albendezole 200 mg orally twice a day for 20-30 d is the treatment of choice. All the patients were cured, and relapses were not observed within 12 mo.

    Full Text Available Background: Alopecia can be a manifestation of mycosis fungoides (MF; however, the prevalence is unknown. Aims: We sought to describe the clinicopathologic presentation of alopecia in patients with diagnosis of MF. Methods: A retrospective analysis of patients with biopsy-proven MF, who were evaluated at our cancer center from 2002 to 2012, was performed to identify patients with alopecia. Results: Five patients with alopecia were identified from reviewing of 157 patients with MF. The male:female ratio was 3:2, and the mean age of patients was 42.8 years. Two of these patients showed patchy hair loss on scalp which was clinically identical to alopecia areata. In remaining three patients, hair loss was seen in areas of MF lesions, and epidermal changes consisted of patch- and plaque-type lesions of MF, tumors, and follicular lesions (follicular MF were also present. In two of these patients, lymphadenopathy without any visceral involvement was detected. Conclusions: Alopecia was observed in 5 (3.18% patients with MF, which makes it a rare finding, which included alopecia areata-like patchy loss in 2 and alopecia within MF lesions in 3.

    Twenty-six, ten-week-old mink were infected by force feeding by pipette 2 ml of a tissue suspension containing a Wisconsin strain of mink enteritis virus. Four days later, diarrhea and partial or complete loss of appetite developed simultaneously in all of the animals. Squinting and occasional vomiting were also observed. By the sixth day after inoculation, all of the mink were anorectic and weak. Anorexia persisted for 48 to 96 hours. Diarrhea and vomiting continued until the eighth to ninth day after exposure. For the first two days after the appearance of diarrhea, the feces contained large quantities of mucus and intestinal casts were seen frequently in the droppings. Thereafter, the feces consisted mostly of yellowish green, watery fluid and contained no casts. Some of the animals died on the eighth day after infection. Those which survived were severely dehydrated and debilitated, but resumed eating and achieved complete clinical recovery within the next five to six days.Leukopenia, i.e., total leukocyte count of less than 5,000 cells per mm(3) of blood, was found in seven of nine mink examined during the height of the disease. Leukopenic animals were deficient in both lymphocytes and neutrophils.

    Vasculitic peripheral neuropathy (VPN) occurs due to ischemic changes of peripheral nerves, resulting from a deficit of vascular blood supply due to damaged vasa nervorum leading to vasculitis. VPN usually manifests as sensorimotor or sensory disturbances accompanied by pain, presenting as a type of multiple mononeuropathy, with a scattered distribution in distal limbs. VPN may also present as a mononeuropathy, distal symmetric polyneuropathy, plexopathy, or radiculopathy. The rapidity of VPN is variable, ranging from days to months, with symptoms occasionally changing with the appearance of new lesions. Careful history taking and neurological examination provides an exact diagnosis. The most common cause of VPN is primary vasculitis predominantly affecting small vessels, including vasa nervorum, anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, and polyarteritis nodosa. Similar vasculitic processes can also result from a systemic collagen disorder or secondary vasculitis. Electrophysiological studies and pathological investigation of biopsied peripheral nerves and muscles are important for diagnosis of vasculitis. Serological tests, including ANCA, are useful for diagnosis of vasculitis. Accurate neurological examinations are essential for diagnosis and evaluation of clinical course.

  6. Symptomatic cranial neuralgias in multiple sclerosis: clinical features and treatment.

    2012-02-01

    In multiple sclerosis, neuropathic pain is a frequent condition, negatively influencing the overall quality of life. Cranial neuralgias, including trigeminal, glossopharyngeal neuralgias, as well as occipital neuralgia, are typical expression of neuropathic pain. Neuralgias are characterised by paroxysmal painful attacks of electric shock-like sensation, occurring spontaneously or evoked by innocuous stimuli in specific trigger areas. In multiple sclerosis, demyelination in the centrally myelinated part of the cranial nerve roots plays an important role in the origin of neuralgic pain. These painful syndromes arising in multiple sclerosis are therefore considered "symptomatic", in contrast to classic cranial neuralgias, in which no cause other than a neurovascular contact is identified. At this time, the evidence on the management of symptomatic cranial neuralgias in multiple sclerosis is fragmentary and a comprehensive review addressing this topic is still lacking. For that reason, treatment is often based on personal clinical experience as well as on anecdotal reports. The aim of this review is to critically summarise the latest findings regarding the pathogenesis, the diagnosis, the instrumental evaluation and the medical as well as neurosurgical treatment of symptomatic trigeminal, glossopharyngeal and occipital neuralgia in multiple sclerosis, providing useful insights for neurologists and neurosurgeons and a broad range of specialists potentially involved in the treatment of these painful syndromes.

    Background An eruption cyst (EC) is a benign, developmental cyst associated with a primary or permanent tooth. This paper presents 66 ECs in 53 patients who reported to 3 different centers in Turkey between 2014-2015. Material and Methods 53 patients (31 male, 22 female) with 66 ECs were diagnosed and treated over a 1-year period. The mean age of patients was 5.4 years (minimum 5 months, maximum 11 years). Clinical examination and periapical radiographs were used to establish diagnosis. Age, gender, site, history of trauma and type of treatment were recorded. Results Of the 66 ECs diagnosed in 53 patients, more than half (56.6%) were located in the maxilla, with the maxillary first primary molars the teeth most commonly associated with ECs (30.3%). Multiple ECs were diagnosed in 13 of the 53 patients. ECs had previously diagnosed in the primary dentition of 2 patients, 3 patients reported a history of trauma to primary teeth. In the majority of patients (46 cases, 86.8%), no treatment was provided, whereas surgical treatment was provided in the remaining 7 cases (13.2%). Conclusions Eruption cysts are usually asymptomatic and do not require treatment;. however, if the cyst is symptomatic, it should be treated with simple surgical excision. Key words:Odontogenic cyst, children, eruption cyst, oral pathology. PMID:28160586

    Myriads of physical stress factors including pheochromocytoma have been reported triggering takotsubo syndrome (TS). The aim of this study was to report on the clinical features and outcome of pheochromocytoma-induced TS (Pheo-TS) in a large cohort of patients. Eighty published cases of Pheo-TS were retrieved from the literature and compared with 1,750 cases of all patients with TS (All-TS) published recently by Templin et al. Patients with Pheo-TS were on average 19.87 years younger than those with All-TS (p cases had basal TS pattern compared with 2.2% of cases in All-TS (p cases in All-TS. Two thirds of Pheo-TS cases (67.9%) developed complications, which was significantly higher than complication rates in All-TS (21.8%), but there was no difference in the inhospital mortality between the 2 studies. The most important risk factors for the development of complications in Pheo-TS were age clinical presentation with high complication rates and relatively high recurrence rate. Patients with Pheo-TS are significantly younger than All-TS. The TS localization pattern in Pheo-TS differed significantly from All-TS with basal pattern in almost 1/3 of cases and global pattern in 1/5 of the cases.

    Evidence implicating genetic or prenatal-perinatal environmental causes in the familial aggregation of schizophrenia led us to study 53 sets of siblings, two or more of whom had chronic psychosis, either schizophrenia or schizoaffective disorder. We looked for similarities in clinical features and concordance of diagnosis within sibships to test for shared familial causes. Clinical variables, including diagnosis, specific symptoms, age at onset, and nongenetic perinatal factors, were studied. Auditory hallucinations, paranoid delusions, thought disorder, negative symptoms, and poor premorbid social adjustment did not significantly correlate in siblings. Concordance was found for schizoaffective disorder and history of major depressive episodes, suggesting that schizophrenia with a depressive component and Research Diagnostic Criteria schizoaffective illness may represent a specific etiologic subtype(s) of the illness, whereas the other noted symptoms may represent the variable expression of the disorder. Age at onset and at first hospitalization were significantly correlated, consistent with genetic or other familial factors on time of onset. Birth complications were significantly more frequent among the schizophrenic compared with non-psychotic siblings, had a familial component, and tended to be associated with an earlier age at onset. Thus, nongenetic perinatal factors may increase the risk for schizophrenia in a familial form of the illness and contribute to the correlation of ages at onset in siblings.

    Coronary (artery) spasm plays an important role in the pathogenesis of ischemic heart disease, including stable angina, unstable angina, myocardial infarction, and sudden death. The prevalence of coronary spasm differs among populations, is higher in Japan and Korea than in the Western countries probably due to genetic as well as environmental factors. Coronary spasm occurs most often from midnight to early morning and is usually not induced by exercise in the daytime. The attacks of coronary spasm are associated with either ST segment elevation or depression, or negative U wave on ECG. Patients with multi-vessel coronary spasm may suffer from lethal arrhythmia, including advanced AV block, ventricular tachycardia or fibrillation, or even sudden death, and they are often resistant to conventional medical therapy including Ca-channel blockers (CCBs). Endothelial nitric oxide (NO) activity is reduced and markers of oxidative stress are elevated in patients with coronary spasm. Thrombogenesis is enhanced and plasma levels of hsCRP and P-selection are elevated in patients with coronary spasm. Thus, patients with coronary spasm have endothelial dysfunction and are suffering from a low-grade chronic inflammation. Polymorphisms of endothelial NO synthase, smoking, and low-grade inflammation are the most important risk factors for coronary spasm. Coronary spasm is a hyper-contraction of coronary smooth muscle triggered by an increase of intracellular Ca2+ in the presence of an increased Ca2+ sensitivity. It has been shown that RhoA/ROCK pathway is involved in Ca2+ sensitivity and that the reduced endothelial NO activity results in increased Ca2+ sensitivity through enhanced RhoA/ROCK pathway. Accordingly, it is possible that in addition to CCBs, RhoA/ROCK pathway blockers may prove to be useful for the treatment of coronary spasm.

    Full Text Available Context: Cartilage-hair hypoplasia is a rare hereditary cause of short stature. The aim of this study was to familiarize physicians with this rare but important disease. Evidence Acquisition: This article is a narrative review of the scientific literature to inform about clinical features and management of Cartilage-hair hypoplasia. A systematic search identified 127 papers include original and review articles and case reports. Results: Cartilage-Hair Hypoplasia characterized by short-limb dwarfism associated with metaphyseal chondrodysplasia. The inheritance is autosomal recessive. Other findings include hair hypoplasia, anemia, immunodeficiency, propensity to infections, gastrointestinal disorders (Hirschsprung disease, anal stenosis, esophageal atresia and malabsorption, defective spermatogenesis, increased risk of malignancies and higher rate of mortality. Immunodeficiency in cartilage-hair hypoplasia may be an isolated B-cell or isolated T-cell immunodeficiency or combined B and T-cell immunodeficiency; however, severe combined immunodeficiency is rare. There is no known treatment for hair hypoplasia. Growth hormone was used with conflicting results for short stature in children with Cartilage-hair hypoplasia. Skeletal problems must be managed with physiotherapy and appropriate orthopedic interventions. Hirschsprung disease, anal stenosis and esophageal atresia should be surgically corrected. Patients with severe hypoplastic anemia require repeated transfusions. Bone marrow transplantation may be required for patients with severe combined immunodeficiency or severe persistent hypoplastic anemia. Treatment with G-CSF is useful for neutropenia. Patients should be monitored closely for developing malignancy such as skin neoplasms, lymphomas and leukemias. Conclusions: Cartilage-hair hypoplasia is an important hereditary disease with different medical aspects. The high rate of consanguineous marriages in Iran necessitates considering CHH in any

    Objective: To explore the risk factors and clinical manifestation of coronary lesions in patients with premature coronary heart disease (PCHD), and to prior intervention and optimize therapeutic. Methods: A retrospective analysis of 373 cases of coronary artery disease patients underwent coronary angiography confirmed, 188 patients with PCAD and 185 patients with late CHD (LCHD) were divided by age. The relationship among the risk factors including body mass index (BMI), history of hypertension, diabetes, hyper-lipemia, smoking, alcohol consumption, premature family history of cardiovascular disease, and level of lipidemia, glucose, uricemia, bilirubin and clinical features of coronary lesions in coronary features were analyzed. Results: Patients with PCHD had higher levels of BMI, triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c) and LP(a) compared with the LCAD group (P<0.05). The PCAD group had lower rate of diabetes (P<0.05), and hypertension (P>0.05). The patients with PCHD had lesions in single coronary artery (P<0.05). Conclusion: Patients with PCHD had many clinical cardiovascular risk factors, including obesity, smoking, alcohol consumption, premature family history of cardiovascular disease, hyperlipemia is a major risk factor for PCHD, so early preventing can help reduce the incidence of PCHD. The patients with PCHD had more single vessel disease. These patients were given a reasonable stent and the optimized drugs, which can significantly improve the prognosis.%目的:分析早发冠心病患者临床危险因素及冠脉病变的特点,以便对其早期干预及优化治疗.方法:回顾性分析373例在我院行冠脉造影术确诊为冠心病的患者,按年龄分为早发冠心病组188例(男≤55岁,女≤ 65岁)和晚发冠心病组185例,对两组患者的体重指数(BMI)、高血压病史、糖尿病史、高血脂病史、吸烟史、饮酒史、早发心血管病家族史,血脂、血糖、尿

    Introduction Severe right ventricular hypertrophy (SRVH) is a rare phenotype in hypertrophic cardiomyopathy (HCM) for which limited information is available. This study was undertaken to investigate the clinical, prognostic and genetic characteristics of HCM patients with SRVH. Methods HCM with SRVH was defined as HCM with a maximum right ventricular wall thickness ≥10 mm. Whole-genome sequencing (WGS) was performed in HCM patients with SRVH. Multivariate Cox proportional hazards regression models were used to identify risk factors for cardiac death and events in HCM with SRVH. Patients with apical hypertrophic cardiomyopathy (ApHCM) were selected as a comparison group. The clinical features and outcomes of 34 HCM patients with SRVH and 273 ApHCM patients were compared. Results Compared with the ApHCM group, the HCM with SRVH group included younger patients and a higher proportion of female patients and also displayed higher cardiovascular morbidity and mortality. The multivariate Cox proportional hazards regression models identified 2 independent predictors of cardiovascular death in HCM patients with SRVH, a New York Heart Association class ≥III (hazard ratio [HR] = 8.7, 95% confidence interval (CI): 1.43-52.87, p = 0.019) and an age at the time of HCM diagnosis ≤18 (HR = 5.5, 95% CI: 1.24-28.36, p = 0.026). Among the 11 HCM patients with SRVH who underwent WGS, 10 (90.9%) were identified as carriers of at least one specific sarcomere gene mutation. MYH7 and TTN mutations were the most common sarcomere mutations noted in this study. Two or more HCM-related gene mutations were observed in 9 (82%) patients, and mutations in either other cardiomyopathy-related genes or ion-channel disease-related genes were found in 8 (73%) patients. Conclusions HCM patients with SRVH were characterized by poor clinical outcomes and the presentation of multiple gene mutations. PMID:28323875

    Although a variant of primary biliary cirrhosis (PBC) characterized by features of autoimmune hepatitis (AIH) has been recognized for many years, few studies with ample numbers of patients have focused on its natural history. This study aimed to clarify the natural history, prognosis, and response to therapy in a cohort of patients with PBC with AIH features. We retrospectively analyzed 277 PBC patients without AIH features and 46 PBC patients with AIH features seen between September 2004 and April 2014. The 5-year adverse outcome-free survival of PBC patients with AIH features was 58% compared to 81% in PBC patients without AIH features. Multivariate analysis in the patients with AIH features indicated that total bilirubin ≥ 2.70× the upper limit of normal predicted a poor prognosis (p = 0.008, relative risk 8.39, 95% confidence interval (CI) 1.73, 40.73). Combination therapy with ursodeoxycholic acid (UDCA) and immunosuppression provided better short-term responses in PBC patients with AIH features, defined by multiple criteria. Higher aspartate aminotransferase (AST) level at accession suggested better prognosis for PBC patients with AIH features while worse prognosis for PBC patients without AIH features. PBC patients with AIH features differ from those without AIH features in terms of natural history, prognostic indicators, and response to therapy.

    The incidence of colorectal carcinoma has increased among patients or =40 years of age served as controls. Cases were evaluated for clinical risk factors of malignancy and pathologic features predictive of outcome. The tumors were immunohistochemically stained for O6-methylguanine methyltransferase, MLH-1, MSH-2, MSH-6, beta-catenin, chemokine (C-X-C motif) receptor 4, epidermal growth factor receptor, TP53, p16, survivin, and alpha-methylacyl-CoA racemase; assessed for microsatellite instability and mutations in beta-catenin, APC, EGFR, PIK3CA, KRAS, and BRAF; evaluated for micro-RNA expression (miR-21, miR-20a, miR-183, miR-192, miR-145, miR-106a, miR-181b, and miR-203); and examined for evidence of human papillomavirus infection. One study patient each had ulcerative colitis and hereditary nonpolyposis colorectal cancer. Ninety-two percent of tumors from young patients occurred in the distal colon (P=0.006), particularly the rectum (58%, P=0.02), and 75% were stage III or IV. Tumors from young patients showed more frequent lymphovascular (81%, P=0.03) and/or venous (48%, P=0.003) invasion, an infiltrative growth pattern (81%, P=0.03), and alpha-methylacyl-CoA racemase expression (83%, P=0.02) compared with controls. Carcinomas in this group showed significantly increased expression of miR-21, miR-20a, miR-145, miR-181b, and miR-203 (P< or =0.005 for all comparisons with controls). These results indicate that early-onset carcinomas commonly show pathologic features associated with aggressive behavior. Posttranslational regulation of mRNA and subsequent protein expression may be particularly important to the development of colorectal carcinomas in young patients.

    Full Text Available Background: Children are one of the most vulnerable groups of the society and are constantly threatened by different people in their family or society. The aim of this study was investigating the correlation of child abuse with personality features and high risk behavior in high school students of Islamshahr, Iran. Methods: This study cross-sectional analytical was conducted on the high school girls and boys of Islamshahr in spring 2014.528 students were selected by cluster random sampling among 4 high schools (two female and two male high schools. Childhood trauma questionnaire, NEO-Five Factor Inventory and Youth Risk-Taking Scale were used for data collection. Data were analyzed by independence t-test, Pearson's correlation coefficient and multiple linear regression. Results: The results of independence t-test indicated significant differences between girls and boys in terms of child abuse and high risk experience (t=-2.16,p=0.03 and t=-5.03, P=0.001, respectively. Also, the results demonstrated a significant relationship between child abuse and personality characteristics, high risk behavior and all its subscales (P<0.05. The findings of multiple linear regressionindicated that child abuse could explain 14% total risk-taking, 25% neurotic personality feature , 14% extroversion, 10% agreeableness, 1% flexibility and 13% conscientiousness (P<0.05. Conclusion: According to the research findings, appropriate behavior with children is of great importance. Therefore, child abuse would form inappropriate personality features and increase risk behaviors among children.

    Large-scale food poisoning caused by methylmercury was identified in Minamata, Japan, in the 1950s (Minamata Disease). Although the diagnostic criteria for the disease was controversial and difficult during that time, we, the Kumamoto University Study Group, carried out a large-scale study to assess the clinical features in 1972-1973. The author tried to reassess the results of that study to appraise the diagnostic criteria established in 1977 on the basis of those results. A substantial number of residents in the exposed area exhibited neurologic signs, especially paresthesia of only the extremities, namely, the male residents of Minamata City showed a positive predictive value of 0.73 and a negative predictive value of 0.23. The relative risks of paresthesia only were 2.6 (2.0-3.3) and 1.2 (0.9-1.5), in Minamata and Goshonoura related to Ariake (control), respectively. At least until 1977, the diagnostic criteria remained valid, although it was inadequate. Nevertheless, presently, a follow-up study of the certified patients may lead to the development of efficient new diagnostic criteria.

    Mycosis fungoides is the most common type of cutaneous T-cell lymphoma (CTCL) and a rare disorder that typically affects older adults with erythematous scaling patches and plaques. Hypopigmented patches are a rare clinical variant of the disease. Granulomatous mycosis fungoides (GMF) is also a rare type of CTCL. No particular clinical criteria are available for the diagnosis of GMF, because of its variable presentations, and so the detection of GMF is primarily considered as a histopathological diagnosis. Rarely, a co-existence of more than one clinical or histopathological feature of mycosis fungoides may be present. To the best of our knowledge this is the first report of MF that shows the simultaneous co-existence of more than one clinical and histopathological variant of MF. We present a 29-year-old female with clinical presentations of both classic and hypopigmented mycosis fungoides (MF), and also the histopathological features of the classic and granulomatous types of the disease.

    Pancreatitis is a rare, life-threatening complication of systemic lupus erythematosus (SLE). This study aimed to describe the clinical features of acute pancreatitis (AP) and chronic pancreatitis (CP) in patients with SLE. Data of patients who fulfilled the revised criteria of the American Rheumatism Association for diagnosis of SLE were retrospectively analyzed. SLE activity was graded according to the SLE Disease Activity Index. Logistic regression analysis was conducted to find out independent associations. Survival rates were estimated by using Kaplan-Meier plots. This study included 5665 SLE patients admitted between January 1983 and January 2014, of whom 52 patients were diagnosed with pancreatitis. Pancreatitis prevalence in SLE patients was 0.92 % (52/5665). AP (0.8 %, 46/5665) was more prevalent than CP (0.1 %, 6/5665), presented mostly during active SLE, and affected more organs. Hypertriglyceridemia occurred in 76.9 % of AP patients and in none of the CP patients. AP patients were divided into severe (n = 10) or mild (n = 20) cases. The average triglyceride level in severe AP cases was higher than that in mild AP cases (P = 0.006), and the mortality rate of lupus-associated AP was 32.6 % (15/46). Concomitant infections and thrombocytopenia were independently associated with poor prognosis (P < 0.001, P = 0.028, respectively). There were significant differences in the clinical manifestations of AP and CP. Patients with severe AP were found to have a higher incidence of concomitant infection and serum triglyceride levels. Concomitant infections and thrombocytopenia were independent risk factors for poor prognosis.

    Full Text Available Background: Rheumatic diseases are among the most prevalent diseases recognized in the world. Musculoskeletal disorders are one of the main causes of disability around the world and expend a large amount of health care and social resources and have a substantial impact on the quality of life of those affected. To identify preventable risk factors and to gain insights into the burden of the diseases, it is important to know the prevalence and demographics of them. Herein we are to describe the pattern of different rheumatic disorders and characteristics of the patients attending in rheumatology clinics in Yazd, Iran, with addressing some different points of views in this regards. Materials and Methods:In this retrospective study, medical records of all patients referred to two main referral rheumatology clinics in Yazd from March 2009 to February 2010 were reviewed. A questionnaire including sex, age, chief complaint, diagnoses, and co-morbid diseases was used for gathering the data. Results:All medical records were reviewed, of whom 5187 patients had specific diagnoses. The mean age of the patients was 38.57 year ± 19.4 SD. 70.81% were females and 29.19% were males. The most common diagnoses were: degenerative joint disease (58.33%, autoimmune disorders (17.88%, and soft tissue rheumatism (12.47%. The most frequent complaints were knee pain (32%. 55.6% of the patients were overweight (BMI >29 and 923 (17.8 % of the patients had diabetes mellitus. Conclusion: Our findings were similar to other studies from Iran and the other countries in most features. The prevalence of autoimmune disorders was rather higher than the other studies; this is perhaps due to our belief that some of periarthritis conditions were part of systemic autoimmune diseases by careful history taking and using pertinent laboratory investigations.

    Introduction: Osteoradionecrosis (ORN) of the jaws is defined as exposed irradiated bone that fails to heal over a period of 3 months without the evidence of a persisting or recurrent tumor. In the previous decades, numerous factors were associated with the risk of ORN development and severity. Aims: The purposes of this study were to present the data of the patients that were treated for ORN in the Department of Oral and Maxillofacial Surgery in Munich (LMU), to detect factors that contributed to the onset of ORN, to identify risk factors associated with the severity of ORN and finally, to delineate and correlate these factors with the personal, health and treatment characteristics of the patients. Material and Methods: A retrospective study was conducted during the period from January 2003 until December 2012 that included all ORN cases having been treated in the Department of Oral and Maxillofacial Surgery in Munich (LMU). The total sample was categorized in three groups according to stage and several variables were evaluated in an attempt to identify possible correlations between them and the necrosis severity. Results: One hundred and fifty three cases of ORN were documented. Among them, 23 (15.1%) cases were stage I, 31 (20.2%) were stage II and 99 (64.7%) were stage III and all localised in the mandible. There was a predominance of the disease in the posterior region when compared to the anterior region. The majority of cases was addicted to alcohol and tobacco abuse and was suffering from Diabetes Mellitus (DM). All cases were treated with RT and 80.4% of them with concomitant chemotherapy. The initial tumor was predominantly located in the floor of the mouth, the tongue and the pharynx. Approximately two thirds of the cases occured either after dental treatment or due to a local pathological condition. Logistic regression analysis identified Diabetes Mellitus (OR: 4.955, 95% Cl: 1.965-12.495), active smoking (OR: 13.542, 95% Cl: 2.085-87.947), excessive

    Prior to 2010, several ISS crewmembers returned from spaceflight with changes to their vision, ranging from a mild hyperopic shift to frank disc edema. As a result, NASA expanded clinical vision testing to include more comprehensive medical imaging, including Optical Coherence Tomography and 3 Tesla Brain and Orbit MRIs. The Space and Clinical Operations (SCO) Division developed a clinical practice guideline that classified individuals based on their symptoms and diagnoses to facilitate clinical care. For the purposes of clinical surveillance, this classification was applied retrospectively to all crewmembers who had sufficient testing for classification. This classification is also a tool that has been leveraged for researchers to identify potential risk factors. In March 2014, driven in part by a more comprehensive understanding of the imaging data and increased imaging capability on orbit, the SCO Division revised their clinical care guidance to outline in-flight care and increase post-flight follow up. The new clinical guidance does not include a classification scheme

    Although clinicopathologic correlation is critical in the diagnosis of early mycosis fungoides (MF), how clinical information directly affects the pathologist's interpretation is unknown. This pilot study aimed to assess the influence of provided clinical information and specific histopathologic features on the histopathologic diagnosis of MF vs. its inflammatory simulants. A computerized survey recorded diagnostic impressions by 24 dermatopathologists of 30 hematoxylin-eosin stained images, including 15 MF images and 15 dermatitis images. Images were accompanied by concordant clinical descriptions (33%), no clinical information (33%) or discordant clinical descriptions (33%). Percentage of correctly classified MF histopathologic images for the three scenarios of concordant clinical information, no clinical information or discordant clinical information were 32% (kappa 0.19), 56% (kappa 0.12) and 16% (kappa 0.33), respectively. The percentage of correctly classified slides presented with no clinical information was different from the other two groups (p < 0.0001). Pautrier collections were most associated with correct classification. Clinical information may play a significant role in the histopathologic diagnosis of MF, although there may be some value in initial blinded histopathologic interpretation. Specific histopathologic features differ in relative importance in the diagnosis of MF.

Today, more than 40 so-called pressure ulcer risk assessment scales are available but still there is an ongoing debate about their usefulness. From a measurement point of view pressure ulcer (PU risk assessment scales have serious limitations. Empirical evidence supporting the validity of PU risk assessment scale scores is weak and obtained scores contain varying amounts of measurement error. The concept of pressure ulcer risk is strongly related to the general health status and severity of illness. A clinical impact due do the application of these scales could also not be demonstrated. It is questionable whether completion of standardized pressure ulcer risk scales in clinical practice is really needed.Keywords: Braden pressure ulcer, prevention, risk assessment, nursing assessment, predictive value, clinical effectiveness, review

    Clonal cytogenetic abnormalities are found in 20-30% of patients with chronic myelomonocytic leukemia (CMML), while gene mutations are present in >90% of cases. Patients with low risk cytogenetic features account for 80% of CMML cases and often fall into the low risk categories of CMML prognostic scoring systems, but the outcome differs considerably among them. We performed targeted deep sequencing of 83 myeloid-related genes in 56 CMML patients with low risk cytogenetic features or uninformative conventional cytogenetics (CC) at diagnosis, with the aim to identify the genetic characteristics of patients with a more aggressive disease. Targeted sequencing was also performed in a subset of these patients at time of acute myeloid leukemia (AML) transformation. Overall, 98% of patients harbored at least one mutation. Mutations in cell signaling genes were acquired at time of AML progression. Mutations in ASXL1, EZH2 and NRAS correlated with higher risk features and shorter overall survival (OS) and progression free survival (PFS). Patients with SRSF2 mutations associated with poorer OS, while absence of TET2 mutations (TET2wt) was predictive of shorter PFS. A decrease in OS and PFS was observed as the number of adverse risk gene mutations (ASXL1, EZH2, NRAS and SRSF2) increased. On multivariate analyses, CMML-specific scoring system (CPSS) and presence of adverse risk gene mutations remained significant for OS, while CPSS and TET2wt were predictive of PFS. These results confirm that mutation analysis can add prognostic value to patients with CMML and low risk cytogenetic features or uninformative CC. PMID:27486981

    The prognosis of patients with HCC still remains dismal. The life expectancy of HCC patients is hard to predict because of the high possibility of postoperative recurrence. Many factors, such as patient's general conditions, macroscopic tumor morphology, as well as tumor hictopathology features, have been proven of prognostic significance. Female HCC patient often has a better prognosis than male patient, which might be due to the receptor of sex hormones. Younger patients often have tumors with higher invasiveness and metastatic potentials, and their survival and prognosis are worse than the older ones. Co-existing hepatitis status and hepatic functional reserve have been confirmed as risk factors for recurrence. Serum alpha-fetoprotein (AFP) is useful not only for diagnosis, but also as a prognostic indicator for HCC patients. AFP mRNA has been proposed as a predictive marker of HCC cells disseminated into the circulation and for metastatic recurrence. Many pathologic features,such as tumor size, number, capsule state, cell differentiation, venous invasion, intrahepatic spreading, and advanced pTNM stage, are the best-established risk factors for recurrence and important aspects affecting the prognosis of patients with HCC. Marked inflammatory cell infiltration in the tumor could predict a better prognosis. Clinical stage is still the most important factor influencing on the prognosis. Extratumor spreading and lymph nodal metastasis are independent predictors for poor outcome. Soma new predictive systems have recently been proposed. Different strategies of treatment might have significant different effects on the patients'prognosis. To date, surgical resection is still the only potentially curative treatment for HCC,including localized postoperative recurrences.Extent of resection, blood transfusion, occlusion of porta hepatis, and blood loss affect the survival and prognosis of HCC patients. Regional therapies provide alternative ways to improve the prognosis of

    as a risk factor for clinical depression. METHOD: We identified published cohort studies from a systematic literature search in PubMed and PsycNET and obtained 14 cohort studies with unpublished individual-level data from the Individual-Participant-Data Meta-analysis in Working Populations (IPD.......94-1.65), but attenuated on adjustment for a continuous depressive symptoms score (RR = 1.03, 95% CI 0.81-1.32). CONCLUSIONS: Job strain may precipitate clinical depression among employees. Future intervention studies should test whether job strain is a modifiable risk factor for depression.......BACKGROUND: Adverse psychosocial working environments characterized by job strain (the combination of high demands and low control at work) are associated with an increased risk of depressive symptoms among employees, but evidence on clinically diagnosed depression is scarce.

    Full Text Available Perinatal period may pose a great challenge for the clinical management and treatment of psychiatric disorders in women. In fact, several mental illnesses can arise during pregnancy and/or following childbirth. Suicide and infanticide have been considered relatively rare events during the perinatal period. However, in some mental disorders (i.e. postpartum depression, bipolar disorder, postpartum psychosis, etc. have been reported a higher risk of suicidal ideation, suicide attempt or suicide. Therefore, a complete screening of mothers’ mental health should also take into account thoughts of suicide and thoughts about harming infants as well. Clinicians should carefully monitor and early identify related clinical manifestations, potential risk factors and alarm symptoms related to suicide. The present paper aims at providing a focused review about epidemiological data, risk and protective factors and an overview about the main clinical correlates associated with the suicidal behaviour during the pregnancy and postpartum period.

    Sjögren’s syndrome (SS) is a chronic inflammatory systemic autoimmune disease. The disease spectrum extends from sicca syndrome to systemic involvement and extraglandular manifestations, and SS may be associated with malignancies, especially non-Hodgkin’s lymphoma. Patients with SS present a broad spectrum of serologic features. Certain serological findings are highly correlated with specific clinical features, and can be used as prognostic markers.

    Background Pancreatitis complicating HIV infection, even in the Highly Active Antiretroviral Therapy (HAART) era, remains a management challenge. We felt there is a need to discern patterns in the biochemical markers, radiological studies, co-infections, length of stay (LOS) in patients with HIV or AIDS AND pancreatitis. Methods This is a retrospective study conducted from June, 2008 to August, 2010 on patients admitted with acute pancreatitis to our hospital. We extracted and compared the following parameters: biochemical markers, HBV markers (surface antigen, core antibody and surface antibody), HCV antibody, radiological studies, and length of stay (LOS). The Balthazar Grade score was used to assess radiological severity of disease. We stratified the cohort into comparison subsets according to CD4 count. Results Ninety-four admissions met the criteria for HIV or AIDS AND pancreatitis; 67 unique patients comprised the cohort. Median age was 48 years (range, 23 to 60 years). Thirty seven (55%) were male, 30 (45%), female. Two third (n = 51) (76%) were African American. Known risk factors included a history of pancreatitis, 17 (25%); cholecystitis, 13 (19%); alcohol abuse, 25 (37%); Intravenous drug abuse, 18 (27%). Only 36 (38%) admissions were on HAART regimen. Biochemical features on admission were: WBC, 6,100/mm3 (900 - 25,700); amylase, 152 U/L (30 - 1,344); lipase, 702.5 U/L (30 - 5,766), triglyceride, 65 mg/dL (57 - 400); glucose, 94 mg/dL (60 - 1,670); lactate, 2.3 mmol/L (1.09 - 5.49); AST, 61.5 U/L (9 - 1,950); LDH, 762 U/L (394 - 5,500); bicarbonate 19.5 mEq/L (3.3 - 82.7). Interestingly, 62% patients had normal pancreas on CT scan on admission. Of 67 individuals, hepatitis profile was available in 43, 21 (49%) were positive for HCV, 11 (26%) had markers for HBV. Four of 11 patients (36) with CD4 200. P = 0.03 via t-test comparison. One patient with CD4 < 50 died due to acute pancreatitis. Conclusion Pancreatitis remains a major cause of morbidity in HIV

    Biomedical big data, as a whole, covers numerous features, while each dataset specifically delineates part of them. "Full feature spectrum" knowledge discovery across heterogeneous data sources remains a major challenge. We developed a method called bootstrapping for unified feature association measurement (BUFAM) for pairwise association analysis, and relational dependency network (RDN) modeling for global module detection on features across breast cancer cohorts. Discovered knowledge was cross-validated using data from Wake Forest Baptist Medical Center's electronic medical records and annotated with BioCarta signaling signatures. The clinical potential of the discovered modules was exhibited by stratifying patients for drug responses. A series of discovered associations provided new insights into breast cancer, such as the effects of patient's cultural background on preferences for surgical procedure. We also discovered two groups of highly associated features, the HER2 and the ER modules, each of which described how phenotypes were associated with molecular signatures, diagnostic features, and clinical decisions. The discovered "ER module", which was dominated by cancer immunity, was used as an example for patient stratification and prediction of drug responses to tamoxifen and chemotherapy. BUFAM-derived RDN modeling demonstrated unique ability to discover clinically meaningful and actionable knowledge across highly heterogeneous biomedical big data sets.

    Full Text Available Coronary Artery Disease (CAD is becoming a major cause of morbidity & mortality burden in the developing world. Indians have been associated with a more severe form of CAD that has its onset at a younger age group with a male predominance. A prospective study was carried out to identify the risk factors and to know the emerging clinical profile in acute coronary syndrome (ACS including S T elevation & Non S T elevation myocardial infarction. We enrolled 200 consecutive patients with typical ECG changes & clinical history, admitted in emergency department from January 2009 to December 2009. A predefined Performa was completed in every patient with a detailed clinical history, physical examinations, and investigation studies. The clinical history revealed information about age, gender, risk factors, and modes of presentation and duration of symptoms. The details of physical examination including anthropometric data, vital signs and complete systemic evaluation were recorded. The regions of infarction and rhythm disturbances were also documented. Our study showed a significant male predominance with mean age being 56 years. Tobacco was identified as major risk factors (65% & obesity (BMI more than 25 is least common risk factor (13%.Patients had typical chest pain (94% and ECG showed anterior wall changes in54%. Forty percent patients developed complications, majority being arrhythmias (60% and least common is mechanical complication (2.5% Thus we conclude that ACS is more common in adult male with tobacco being major risk factors in our population.

    2015-06-01

    The study of human genetics has provided substantial insight into cancer biology. With an increase in sequencing capacity and a reduction in sequencing costs, genomics will probably transform clinical cancer genetics. A heritable basis for many cancers is accepted, but so far less than half the genetic drivers have been identified. Genomics will increasingly be applied to populations irrespective of family history, which will change the framework of phenotype-directed genetic testing. Panel testing and whole genome sequencing will identify novel, polygenic, and de-novo determinants of cancer risk, often with lower penetrance, which will challenge present binary clinical classification systems and management algorithms. In the future, genotype-stratified public screening and prevention programmes could form part of tailored population risk management. The integration of research with clinical practice will result in so-called discovery cohorts that will help identify clinically significant genetic variation.

    Percutaneous Coronary Intervention (PCI) is the most common strategy for the treatment of Acute ST segment elevation Myocardial Infarction (STEMI), and thromboaspiration has been increasingly utilized for removal of occlusive thrombi. To analyze the influence of histopathological features of coronary thrombi in clinical outcomes of patients with STEMI, and the association of these variables with clinical, angiographic, and laboratory features and medications used in hospitalization. Prospective cohort study. All patients were monitored during hospitalization and thirty days after the event. Aspirated thrombi were preserved in formalin and subsequently stained with hematoxylin-eosin and embedded in paraffin. Thrombi were classified as recent and old. The primary outcome was the occurrence of major cardiovascular events within thirty days. During the study period, 1,149 patients were evaluated with STEMI, and 331 patients underwent thrombi aspiration, leaving 199 patients available for analysis. It was identified recent thrombi in 116 patients (58%) and old thrombi in 83 patients (42%). Recent thrombi have greater infiltration of red blood cells than old thrombi (p = 0.02), but there were no statistically significant differences between other clinical, angiographic, laboratory, and histopathological features and medications in both group of patients. The rates of clinical outcomes were similar in both groups. Recent thrombi were identified in 58% of patients with STEMI and it was observed an association with infiltration of red blood cells. There was no association between histopathological features of thrombi and clinical variables and cardiovascular outcomes.

    Canavan disease is a rare hereditary leukodystrophy that manifests in early childhood. Associated with rapidly progressive clinical deterioration, it usually results in death by the third year of life. The predominant MRI appearance is diffuse and symmetrical white matter disease. We discuss an atypical, late presentation of Canavan disease with a benign clinical course and uncharacteristic imaging features. This case introduces a previously unreported pattern of diffuse cortical abnormality without significant white matter involvement. (orig.)

    2012-02-01

    Breast cancer is the most common cancer affecting European women and the leading cause of cancer-related death. A total of 15-20% of women who develop breast cancer have a family history and 5-10% a true genetic predisposition. The identification and screening of women at increased risk may allow early detection of breast cancer and improve prognosis. We established a family risk assessment clinic in May 2005 to assess and counsel women with a family history of breast cancer, to initiate surveillance, and to offer risk-reducing strategies for selected high-risk patients. Patients at medium or high risk of developing breast cancer according to NICE guidelines were accepted. Family history was determined by structured questionnaire and interview. Lifetime risk of developing breast cancer was calculated using Claus and Tyrer-Cuzick scoring. Risk of carrying a breast cancer-related gene mutation was calculated using the Manchester system. One thousand two hundred and forty-three patients have been referred. Ninety-two percent were at medium or high risk of developing breast cancer. Formal assessment of risk has been performed in 368 patients, 73% have a high lifetime risk of developing breast cancer, and 72% a Manchester score >or=16. BRCA1\\/2 mutations have been identified in 14 patients and breast cancer diagnosed in two. Our initial experience of family risk assessment has shown there to be a significant demand for this service. Identification of patients at increased risk of developing breast cancer allows us to provide individuals with accurate risk profiles, and enables patients to make informed choices regarding their follow-up and management.

    To determine whether the presence of melancholic features in hospitalized patients with major depressive disorder (MDD) was associated with specific clinical characteristics and treatment outcomes, supporting melancholic depression as a distinct subtype within MDD. 126 acutely ill inpatients with MDD were enrolled in an open, 6-week trial with fixed-dose fluoxetine 20mg daily. Symptom severity was assessed regularly, using the 17-item Hamilton Depression Rating Scale (HAMD-17) and Clinical Global Impression of Severity (CGI-S). Melancholic features were defined according to the DSM-IV criteria. Clinical variables were compared between patients with and without melancholic features. Generalized estimating equations method was used to explore the differences in HAMD-17 and CGI-S scores between the 2 groups over time. Clinical response was defined as having a 50% or greater reduction in HAMD-17 scores. 96 (76.2%) of the 126 patients with at least one post-baseline assessment met the criteria for melancholic depression. Melancholic depression differed from non-melancholic depression in clinical characteristics and predicted a better response to fluoxetine treatment. The differentiation between melancholic and non-melancholic depression within MDD hence is clinically significant and valid.

  2. Special features of high-risk pregnancies as factors in development of mental distress: a review

    Paula Borba Rodrigues

    Full Text Available Abstract Introduction: Approximately 22% of all pregnant women are classified as having high-risk pregnancies, which may involve feelings of vulnerability because of having a high-risk pregnancy, resulting in greater exposure to stressful feelings. Objective: To review aspects of high-risk pregnancy that can have a negative impact on the these women's mental health status. Method: Original articles were identified by conducting searches of the PubMed/MEDLINE, LILACS and SciELO databases, followed by a manual search of references to select articles and additional bibliographic material. Articles from the last 22 years were included in the review (1992-2014. Results: Fifteen articles were found that specifically studied high-risk pregnancies and mental health outcomes. Women with high-risk pregnancies exhibited a significantly higher level of stress and reported negative emotions as they dealt with stress and had worse emotional status than women with normal pregnancies. Researchers found that hospitalized pregnant women had higher levels of anxiety than non-hospitalized women. Studies of women going through normal and high-risk pregnancies show that women with normal pregnancies had good self-perceived quality of life. Conclusion: Special features of high-risk pregnancies could be factors in development of mental distress, in addition to psychological and social factors. Therefore, only a biopsychosocial research study would be able to identify the factors that can affect the quality of mental health during high-risk pregnancy.

    Cerebrovascular risk represents a progressive and evolving concept owing to the particular distribution of risk factors in patients with ischemic stroke and in light of the newest stroke subtype classifications that account for pathophysiological, instrumental, and clinical criteria. Age represents the strongest nonmodifiable risk factor associated with ischemic stroke, while hypertension constitutes the most important modifiable cerebrovascular risk factor, confirmed by a host of epidemiological data and by more recent intervention trials of primary (HOT, Syst-Eur, LIFE) and secondary (PROGRESS) prevention of stroke in hypertensive patients. To be sure, a curious relationship exists between stroke and diabetes. Although the Framingham Study, The Honolulu Heart Program, and a series of Finnish studies reported a linear relationship between improved glucose metabolism and cerebral ischemia, the clinical and prognostic profile of diabetic patients with ischemic stroke remains to be fully understood. Our group, on the basis of TOAST classification--a diagnostic classification of ischemic stroke developed in 1993 that distinguishes five different clinical subtypes of ischemic stroke: large-artery atherosclerosis (LAAS), cardioembolic infarct (CEI), lacunar infarct (LAC), stroke of other determined origin (ODE), and stroke of undetermined origin (UDE), and now extensively used in clinical and scientific context--analysed the prevalence of cerebrovascular risk factors and the distribution of TOAST subtypes in more 300 patients with acute ischemic stroke in two consecutives studies that reported the significant association between diabetes and the lacunar subtype and a better clinical outcome for diabetic patients, most likely related to the higher prevalence of the lacunar subtype. Well-confirmed are the roles of cigarette smoking, atrial fibrillation, and asymptomatic carotid stenosis as cerebrovascular risk factors. Particularly interesting seems to be the function of

    Full Text Available Plasma cell leukemia (PCL is a rare hematologic malignancy with aggressive clinical and biologic features. Data regarding its prognosis with the use of the novel agents, i.e., the immunomodulatory drugs thalidomide and lenalidomide, and the proteasome inhibitor bortezomib, are limited. We retrospectively reviewed clinical outcomes, response to therapy, and survival of 17 patients seen at the Penn State Hershey Cancer Institute since the availability of novel agents (2006-2011. Twelve patients had primary PCL (pPCL, and 5 second- ary PCL (sPCL. PCL was associated with aggressive clinicobiological features, such as high-risk cytogenetics, elevated serum beta-2-microglobulin and lactate dehydrogenase, International Staging System stage III, and rapid relapse after therapy. With the use of thalidomide, lenalidomide, and bortezomib in 53%, 53%, and 88% patients, respectively, median overall survival (OS was 18 months in the whole group (95% confidence interval, 11-21 months, and 21 and 4 months in pPCL and sPCL, respectively (P=0.015. OS was inferior to that of 313 consecutive patients with multiple myeloma (MM treated in the same period, even when compared with a subset of 47 MM with high-risk cytogenetics. Although our data are limited by the small sample size, we conclude that novel agents may modestly improve survival in patients with PCL, when compared to historical controls. Novel therapies do not seem to overcome the negative prognosis of PCL as compared with MM.

    Generalized anxiety disorder (GAD) is a prevalent and disabling disorder characterised by persistent worrying, anxiety symptoms, and tension. General practitioners and mental healthcare professionals frequently misdiagnose the presenting symptoms. This article addresses the clinical presentation of GAD and provides guidelines for discriminating GAD from other disorders, based on theoretical considerations and clinical experience. Debate relating to the validity of the definition of GAD is discussed, and suggestions are made for improving the criteria for GAD, which may guide future versions of classification systems such as the Diagnostic and Statistical Manual.

    Full Text Available Abstract Background The diagnosis of abdominal tuberculosis (TB is difficult, especially so in health care facilities in developing countries where laparoscopy and colonoscopy are rarely available. There is little information on abdominal TB in HIV infection. We estimated the prevalence and clinical features of abdominal (excluding genitourinary TB in HIV infected adults attending the University Teaching Hospital, Zambia. Methods We screened 5,609 medical inpatients, and those with fever, weight loss, and clinical features suggestive of abdominal pathology were evaluated further. A clinical algorithm was used to specify definitive investigations including laparoscopy or colonoscopy, with culture of biopsies and other samples. Results Of 140 HIV seropositive patients with these features, 31 patients underwent full evaluation and 22 (71% had definite or probable abdominal TB. The commonest presenting abdominal features were ascites and persistent tenderness. The commonest ultrasound findings were ascites, para-aortic lymphadenopathy (over 1 cm in size, and hepatomegaly. Abdominal TB was associated with CD4 cell counts over a wide range though 76% had CD4 counts Conclusion The clinical manifestations of abdominal TB in our HIV-infected patients resembled the well-established pattern in HIV-uninfected adults. Patients with fever, weight loss, abdominal tenderness, abdominal lymphadenopathy, ascites and/or hepatomegaly in Zambia have a high probability of abdominal TB, irrespective of CD4 cell count.

    AIM: Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominantly- inherited cancer-susceptibility syndrome that confers an increased risk for colorectal cancer and a variety of other tumors at a young age. It has been associated with germline mutations in five mismatch repair (MMR) genes (hMSH2, hMLH1, hPMS1, hPMS2, and hMSH6/GTBP). The great majority of germline mutations were found in hMSH2 and hMLH1. The purpose of this study was to analyze the clinical features of Chinese HNPCC patients and to screen hMSH2 and hMLH1 gene mutations. METHODS: Twenty-eight independent Chinese families were collected, of which 15 met Amsterdam criteria I and 13 met the Japanese clinical diagnosis criteria. The data were recorded including sex, site of colorectal cancer (CRC),age of diagnosis, history of synchronous and/or metachronous CRC, instance of extracolonic cancers, and histopathology of tumors. Peripheral blood samples were collected from all pedigrees after formal written consents were signed. PCR and denaturing high-performance liquid chromatography (DHPLC) were used to screen the coding regions of hMSH2 and hMLH1 genes. The samples showing abnormal DHPLC profiles were sequenced by a 377 DNA sequencer.RESULTS: One hundred and seventy malignant neoplasms were found in one hundred and twenty-six patients (multiple cancer in twenty-three), including one hundred and twentyseven CRCs, fifteen gastric, seven endometrial, and five esophageal cancers. Seventy-seven point eight percent of the patients had CRCs, sharing the features of early occurrence (average age of onset, 45.9 years) and of the right-sided predominance reported in the literature. In Chinese HNPCC patients, gastric cancer occurred more frequently, accounting for 11.9% of all cancers patients and ranking second in the spectrum of HNPCC predisposing cancers. Synchronous CRCs occurred less frequently, only accounting for 3.1% of the total CRCs. Twenty percent of the colorectal patients had

    Background Hereditary spastic paraplegia is a clinically and genetically heterogeneous group of neurodegenerative disorders of the motor system, characterized by slowly progressive spasticity and weakness of the lower extremities. This study was conducted to investigate the clinical features of hereditary spastic paraplegia with thin corpus callosum (HSP-TCC). Methods Clinical data from five patients and thirty-five previously published case reports of HSP-TCC were analyzed retrospectively. Results Most patients were adolescents at the onset of the disease, presenting with spastic paraparesis of the lower limbs and mental impairment. Some patients also had other clinical features, including spasticity of the upper limbs, cerebellar ataxia, and sensory disturbances. Cranial MRIs of the five patients revealed an extremely thin corpus callosum, sometimes with widened cerebral sulci and ventricles, as well as with cerebellar and cerebral atrophy. Conclusion The main clinical features of HSP-TCC include slowly progressive spastic paraplegia, mental impairment during the second decade of life, and an extremely thin corpus callosum as shown on cranial MRIs.

    Full Text Available Melanoma is an aggressive and rare neoplasm of melanocytic origin. Mucosal melanomas of the head and neck account for 1 % of neoplasms, 0,2–8,0 4 % of all melanomas and over 50 % of all mucosal melanomas. To date, in Russian and foreign literature only few retrospective series and case reports have been reported on mucosal melanoma. Despite melanoma’s common histological origin, head and neck mucosal melanoma presentation has some specific features due to its anatomical localization and poor clinical outcomes compared with those of cutaneous melanomas. Mucosal melanoma has a high metastatic potential. Five-year overall survival does not exceed 30 %. Advances in understanding of the clinical presentation can be used for prediction of behaviour and prognosis of this disease. We considered and analised articles devoted to clinical features of head and neck mucosal melanoma according to its localization.

    Full Text Available Brucellosis is a zoonotic infection and has endemic characteristics. Neurobrucellosis is an uncommon complication of this infection. The aim of this study was to present unusual clinical manifestations and to discuss the management and outcome of a series of 18 neurobrucellosis cases. Initial clinical manifestations consist of pseudotumor cerebri in one case, white matter lesions and demyelinating syndrome in three cases, intracranial granuloma in one case, transverse myelitis in two cases, sagittal sinus thrombosis in one case, spinal arachnoiditis in one case, intracranial vasculitis in one case, in addition to meningitis in all cases. Eleven patients were male and seven were female. The most prevalent symptoms were headache (83% and fever (44%. All patients were treated with rifampicin, doxycycline plus trimethoprim-sulfamethoxazole or ceftriaxone. Duration of treatment (varied 3-12 months was determined on basis of the CSF response. In four patients presented with left mild sequelae including aphasia, hearing loss, hemiparesis. In conclusion, although mortality is rare in neurobrucellosis, its sequelae are significant. In neurobrucellosis various clinical and neuroradiologic signs and symptoms can be confused with other neurologic diseases. In inhabitants or visitors of endemic areas, neurobrucellosis should be kept in mind in cases that have unusual neurological manifestations.

    Full Text Available Background: Suicidal behavior is a critical problem among military veterans. Therefore, it is important to identify psychological suicide risk factors that are unique for veterans of military service. We compared clinical features of 55 veteran suicide attempters with 55 veterans without a history of suicide attempts. Methods: Demographic and clinical characteristics of suicide attempters and non-attempters were assessed and recorded. Based on the Scale for Suicide Ideation (SSI all patients were divided into two groups: patients who do not report any suicidal ideation at all (non-ideators and people who do (ideators. Results: There was no difference between the groups with regard to age (t= − 0.71, df = 108, p=0.48, gender (χ2=1.50, df = 1, p=0.36, and race (χ2=4.84, df = 5, p=0.44. There were more subjects with a lifetime history of bipolar disorder, substance dependence, or psychotic disorder among suicide attempters compared to non-attempters (χ2=6.67, df = 1, p=0.01, χ2=4.71, df = 1, p=0.04, and χ2=9.83, df = 1, p = 0.002, respectively. There were 34% of current suicide ideators among suicide attempters and 9.3% of suicide ideators among non-attempters (χ2=9.67, df = 1, p=0.002. There was no difference with regard to the proportion of patients with major depression or posttraumatic stress disorder between suicide attempters and non-attempters (χ2=0.10, df = 1, p=0.83 and χ2=0.41, df = 1, p=0.54, respectively. Conclusion: A history of suicide attempt in military veterans is associated with a lifetime history of bipolar disorder, substance dependence, psychotic disorder, or current suicidal ideation but not with a lifetime history of major depression or posttraumatic stress disorder.

This study was aimed to investigate the clinical features, mortality, and the predictors for mortality of this group of patients. Materials and Methods: Medical records were retrospectively reviewed in Sun Yat-sen Memorial Hospital from 1996 to 2012. Data of demographic information, clinical manifestations, laboratory tests, SLE disease activity index 2000 (SLEDAI-2K score, diagnosis, complications, treatment, and mortality was collected. Results: A total of 124 patients were included in our study. Thirty-five (29.1% patients had glomerular filtration rate <60 ml/min/1.73 m 2 , while 24 (19.4% experienced acute kidney injury (AKI. Thirteen of the 19 American College of Rheumatology defined NPSLE syndromes were identified. The most frequent manifestation was seizure disorder (56/124, 45.2%, followed by psychosis (37/124, 29.8% and cerebrovascular disease (35/124, 28.2%. One hundred and five (84.7% patients had SLEDAI-2K scores ≥15, the mean of which was 21.5 ± 6.2. The mortality during hospitalization was 12.9% (16/124 with NP involvement itself being the leading cause of death (7/16, 43.8%. Multivariate logistic regression confirmed that age <14 years at onset of NPSLE (odds ratios [OR]: 9.95, 95% confidence intervals [CI]: 1.43-69.36, P = 0.020, AKI (OR: 10.40, 95% CI: 2.33-46.48, P = 0.002 and pneumonia (OR: 4.52, 95% CI: 1.14-17.96, P = 0.032 were risk factors for mortality, while cyclophosphamide (CYC treatment (OR: 0.09, 95% CI: 0.02-0.54, P = 0.008 was a protective factor. Conclusion: Most of SLE patients with LN and new-onset NPSLE are in an active disease state. NP manifestation itself was the leading cause of death during hospitalization. Childhood-onset NPSLE, AKI and pneumonia might be predictors of mortality, whereas CYC treatment might improve the prognosis.

    Aim: Nodular regenerative hyperplasia (NRH) and large regenerative nodules (LRN) are distinct types of hepatocellular nodules that have been confused in the radiology literature. However, distinction is critical because their clinical significance is quite different. Our purpose was to review the clinical and imaging findings in a series of patients with NRH and LRN in order to identify distinguishing clinical and imaging features. Materials and methods: This was a retrospective case series. The clinical and imaging features were compared in 36 patients with pathological proof of NRH and 23 patients with pathological evidence of LRN. Results: NRH and LRN have different predisposing factors and imaging findings. NRH is often associated with organ transplantation, myeloproliferative disease, or autoimmune processes. Livers with NRH typically do not have enhancing nodules; none of the present patients with NRH had enhancing liver masses. In contrast, LRN are often associated with Budd-Chiari syndrome. Enhancing liver masses were noted in 19 (83%) of the 23 patients with LRN. The p values for the comparisons were less than 0.001 for both enhancing liver masses and hepatic vein thrombosis. Conclusion: NRH and LRN can have distinct clinical presentations and imaging appearances. LRN often result in enhancing liver nodules, whereas NRH usually does not. Clinical and imaging information enables the distinction of LRN and NRH in many cases.

    Mitochondrial encephalopathy with lactic acidosis and stroke-like episodes (MELAS) mostly occur in children. The point mutation A3243G of mitochondrial DNA (mtDNA) may work as a specific bio-marker for mitochondrial disorders. The related clinical features, however, may vary among individuals. This study therefore investigated the relation between MELAS clinical features and point mutation A3243G of mtDNA, in an attempt to provide further evidences for genetic diagnosis of MELAS. Children with MELAS-like syndromes were tested for both blood lactate level and point mutation A3243G of mtDNA. Further family study was performed by mtDNA mutation screening at the same loci for those who had positive gene mutation at A3243G loci. Those who were negative for A3243G point mutation were examined by muscle biopsy and genetic screening. Both clinical and genetic features were analyzed. In all 40 cases with positive A3243G mutation, 36 children fitted clinical diagnosis of MELAS. In other 484 cases with negative mutation, only 8 children were clinically diagnosed with MELAS. Blood lactate levels in both groups were all elevated (P>0.05). In a further genetic screening of 28 families, 10 biological mothers and 8 siblings of MELAS children had positive A3243G point mutations but without any clinical symptoms. Certain difference existed in the clinical manifestations between children who were positive and negative for A3243G mutation of mtDNA but without statistical significance. MELAS showed maternal inheritance under most circumstances.

    The historical and clinical findings in 200 referred cases of equine sinus disease were reviewed retrospectively. Univariable and multivariable analyses were performed to detect significant differences in historical or clinical features between various categories of sinus disease. The causes of sinus disease were classified as subacute primary (less than two months duration) (n=52), chronic primary (more than two months duration) (n=37), dental (n=40), sinus cyst (n=26), traumatic (n=13) or mycotic sinusitis (n=7), sinus neoplasia (n=10), dental-related oromaxillary fistula (n=8) and intrasinus progressive ethmoid haematoma (n=7). The majority of sinus disorders were of chronic duration at the time of referral and most (including 97 per cent of chronic primary sinusitis cases) had not responded to previous antibiotic therapy and/or sinus lavage in some cases. Clinical signs included unilateral nasal discharge in most cases, including purulent or mucopurulent discharge in all horses with primary, dental and mycotic sinusitis. Haemorrhagic nasal discharge was a feature of traumatic sinusitis and intrasinus progressive ethmoid haematomas. Firm facial swellings and nasal airflow obstruction were features of sinus cysts and neoplasms. Ipsilateral lymphadenitis was a more prominent feature of sinus disease with active infections such as primary, dental or mycotic sinusitis.

    Full Text Available OBJECTIVE: Although the clinical manifestation and risk factors of cerebral microangiopathy (CM remain unclear, the number of diagnoses is increasing. Hence, patterns of association among lesion topography and severity, clinical symptoms and demographic and disease risk factors were investigated retrospectively in a cohort of CM patients. METHODS: Patients treated at the Department of Neurology, University of Bonn for CM (n = 223; 98m, 125f; aged 77.32±9.09 from 2005 to 2010 were retrospectively enrolled. Clinical symptoms, blood chemistry, potential risk factors, demographic data and ratings of vascular pathology in the brain based on the Wahlund scale were analyzed using Pearson's chi square test and one-way ANOVA. RESULTS: Progressive cognitive decline (38.1%, gait apraxia (27.8%, stroke-related symptoms and seizures (24.2%, TIA-symptoms (22% and vertigo (17% were frequent symptoms within the study population. Frontal lobe WMLs/lacunar infarcts led to more frequent presentation of progressive cognitive decline, seizures, gait apraxia, stroke-related symptoms, TIA, vertigo and incontinence. Parietooccipital WMLs/lacunar infarcts were related to higher frequencies of TIA, seizures and incontinence. Basal ganglia WMLs/lacunar infarcts were seen in patients with more complaints of gait apraxia, vertigo and incontinence. Age (p = .012, arterial hypertension (p<.000, obesity (p<.000 and cerebral macroangiopathy (p = .018 were positively related to cerebral lesion load. For increased glucose level, homocysteine, CRP and D-Dimers there was no association. CONCLUSION: This underlines the association of CM with neurological symptoms upon admission in a topographical manner. Seizures and vertigo are symptoms of CM which may have been missed in previous studies. In addition to confirming known risk factors such as aging and arterial hypertension, obesity appears to increase the risk as well. Since the incidence of CM is increasing, future

    We report a patient who presented with clinical and MRI findings suggestive of polymyositis but, in whom, muscle biopsy disclosed a strikingly different diagnosis. A 65-year-old woman presented with 3-week history of bilateral proximal muscle pain and weakness. Laboratory investigations showed markedly elevated inflammatory markers and mildly elevated muscle enzymes. MRI scans of lower limbs showed features suggestive of polymyositis. However, muscle biopsy showed features of a polyarteritis-type vasculitis affecting an intramuscular blood vessel. Our reports highlight the critical role of muscle biopsy in establishing the correct diagnosis in patients with suspected myositis.

    Aim: The aim of work was presentation of several socio-demographic, clinical and laboratory characteristics of gastroenteritis caused by rotavirus. The examinees and methods: The examinees were children under the age of five years treated at the Pediatric Clinic due to acute gastroenteritis caused by rotavirus. Rotavirus is isolated by method chromatographic immunoassay by Cer Test Biotec. Results: From the total number of patients (850) suffering from acute gastroenteritis, feces test on bacteria, viruses. protozoa and fungi was positive in 425 (49.76%) cases. From this number the test on bacteria was positive in 248 (58.62%) cases, on viruses it was positive in 165 (39.0%), on protozoa in 9 (2.12%) cases and on fungi only one case. Rotavirus was the most frequent one in viral test, it was isolated in 142 (86.06%) cases, adenoviruses were found in 9 (5.45%) cases and noroviruses in only one case. The same feces sample that contained rotavirus and adenoviruses were isolated in five cases, whereas rotavirus with bacteria was isolated in the same feces sample in five cases. The biggest number of cases 62 (43.66%) were of the age 6-12 months, whereas the smallest number 10 (7.04%) cases were of the age 37-60 months. There were 76 (53.52%) of cases of male gender, from rural areas there were 81 (57.04%) cases and there were 58 (40.80%) cases during the summer period. Among the clinical symptoms the most prominent were diarrhea, vomiting, high temperature, whereas the different degree of dehydration were present in all cases (the most common one was moderate dehydration). The most frequent one was isonatremic dehydration in 91 (64.08%) cases, less frequent one was hypernatremic dehydration in 14 (9.85%) cases. The majority of cases (97.89%) had lower blood pH values, whereas 67 (47.17%) cases had pH values that varied from 7.16 -7.20 (curve peak), normal values were registered in only 3 (2.11%) cases. Urea values were increased in 45 (31.07%) cases (the maximum value

    Purpose To assess the risk of breast cancer in women with false-positive screening results according to radiologic classification of mammographic features. Materials and Methods Review board approval was obtained, with waiver of informed consent. This retrospective cohort study included 521 200 women aged 50-69 years who underwent screening as part of the Spanish Breast Cancer Screening Program between 1994 and 2010 and who were observed until December 2012. Cox proportional hazards regression analysis was used to estimate the age-adjusted hazard ratio (HR) of breast cancer and the 95% confidence interval (CI) in women with false-positive mammograms as compared with women with negative mammograms. Separate models were adjusted for screen-detected and interval cancers and for screen-film and digital mammography. Time without a breast cancer diagnosis was plotted by using Kaplan-Meier curves. Results When compared with women with negative mammograms, the age-adjusted HR of cancer in women with false-positive results was 1.84 (95% CI: 1.73, 1.95; P < .001). The risk was higher in women who had calcifications, whether they were (HR, 2.73; 95% CI: 2.28, 3.28; P < .001) or were not (HR, 2.24; 95% CI: 2.02, 2.48; P < .001) associated with masses. Women in whom mammographic features showed changes in subsequent false-positive results were those who had the highest risk (HR, 9.13; 95% CI: 8.28, 10.07; P < .001). Conclusion Women with false-positive results had an increased risk of breast cancer, particularly women who had calcifications at mammography. Women who had more than one examination with false-positive findings and in whom the mammographic features changed over time had a highly increased risk of breast cancer. Previous mammographic features might yield useful information for further risk-prediction models and personalized follow-up screening protocols.

    Full Text Available The article describes a clinical case of organic depressive disorder in the personality who sustained a traumatic brain injury and who abused alcohol, with distinguishing number of clinical and psychopathological features. Depressed mood, slowed thinking process, sleep disturbances, low self-esteem, hypochondriacal tendencies allowed to diagnose depressive disorder. Clinical history on sustained brain concussion, as well as inertness of nervous and mental processes revealed in psychodiagnostic study testified to organic genesis of the disease. Alcohol abuse by the person having an adverse organic background contributed to appearance of psychotic symptoms in clinical picture. Hallucinatory and delusional inclusions relatively quickly stopped on a background of antipsychotic treatment; this testified that they are secondary to the affective (depressive symptoms.

    Full Text Available Copy number variations involving the 17q12 region have been associated with developmental and speech delay, autism, aggression, self-injury, biting and hitting, oppositional defiance, inappropriate language, and auditory hallucinations. We present a tall-appearing 17-year-old boy with marfanoid habitus, hypermobile joints, mild scoliosis, pectus deformity, widely spaced nipples, pes cavus, autism spectrum disorder, intellectual disability, and psychiatric manifestations including physical and verbal aggression, obsessive-compulsive behaviors, and oppositional defiance. An echocardiogram showed borderline increased aortic root size. An abdominal ultrasound revealed a small pancreas, mild splenomegaly with a 1.3 cm accessory splenule, and normal kidneys and liver. A testing panel for Marfan, aneurysm, and related disorders was negative. Subsequently, a 400 K array-based comparative genomic hybridization (aCGH + SNP analysis was performed which identified a de novo suspected pathogenic deletion on chromosome 17q12 encompassing 28 genes. Despite the limited number of cases described in the literature with 17q12 rearrangements, our proband’s phenotypic features both overlap and expand on previously reported cases. Since syndrome-specific DNA sequencing studies failed to provide an explanation for this patient’s unusual habitus, we postulate that this case represents an expansion of the 17q12 microdeletion phenotype. Further analysis of the deleted interval is recommended for new genotype-phenotype correlations.

  18. Risk stratification in non-ST elevation acute coronary syndromes: Risk scores, biomarkers and clinical judgment

    Clinical guidelines recommend an early invasive strategy in higher risk NSTE-ACS. The Global Registry of Acute Coronary Events (GRACE risk score is a validated risk stratification tool which has incremental prognostic value for risk stratification compared with clinical assessment or troponin testing alone. In emergency medicine, there has been a limited adoption of the GRACE score in some countries (e.g. United Kingdom, in part related to a delay in obtaining timely blood biochemistry results. Age makes an exponential contribution to the GRACE score, and on an individual patient basis, the risk of younger patients with a flow-limiting culprit coronary artery lesion may be underestimated. The future incorporation of novel cardiac biomarkers into this diagnostic pathway may allow for earlier treatment stratification. The cost-effectiveness of the new diagnostic pathways based on high-sensitivity troponin and copeptin must also be established. Finally, diagnostic tests and risk scores may optimize patient care but they cannot replace patient-focused good clinical judgment.

    In patients with meningococcal infection, devastating presentations, such as purpura fulminans, which can progress to extensive tissue necrosis of the limbs and digits, have a significant social impact. The case presented herein illustrates such a phenomenon in a patient who developed bilateral necrosis of the lower extremities as a result of infection with Neisseria meningitis. We emphasize that severe myalgia was the first clinical manifestation of meningococcal purpura fulminans in our case. However, myalgia has typically been overlooked and undervalued as an early clinical feature of meningococcal sepsis. Early recognition and prompt initial antibiotic therapy continue to be the cornerstones of the successful management of this dramatic disease, reducing morbidity and mortality.

    Full Text Available Traumatic subperiosteal hematoma (SpH usually presents late, after the initial trauma. It is generally seen in young males. Computed tomography is the best mode of imaging and helps to rule out orbital fracture or associated subdural hematoma. We present the clinical features and management of four patients seen at the orbit clinic with SpH. Management is based on time of presentation, visual acuity and any communicating bleed. The prognosis of traumatic SpH is excellent if treated with an individualized patient approach.

    It is unknown why some infants with perinatal stroke present clinical symptoms late during infancy and will be identified as infants with presumed perinatal stroke. The risk factors and clinical and radiological data of 42 infants with presumed perinatal stroke (69% with periventricular venous infarction and 31% with arterial ischemic stroke) from the Estonian Pediatric Stroke Database were reviewed. Children with presumed perinatal stroke were born at term in 95% of the cases and had had no risk factors during pregnancy in 43% of the cases. Children with periventricular venous infarction were born significantly more often (82%) vaginally (P = .0213) compared to children with arterial stroke (42%); nor did they require resuscitation (P = .0212) or had any neurological symptoms after birth (P = .0249). Periventricular venous infarction is the most common type of lesion among infants with the presumed perinatal stroke. Data suggest that the disease is of prenatal origin.

    Full Text Available Objective  To discuss the relative and independent risk factors in ectopic pregnancy. Methods  The clinical data of 870 patients with ectopic pregnancy, admitted from 2005 to 2012, were retrospectively analyzed, with 800 cases of normal pregnancy serving as control. Monofactorial correlation analysis was used to analyze the related risk factor, and logistic regression analysis was used to analyze the independent risk factor. Results  Pelvic adhesion, previous operation, cesarean section delivery, number of pregnancy, artificial abortion, medical abortion, in vitrofertilization and embryo replacement (IVF-ER, and placement of intrauterine device (IUD are the risk factors of ectopic pregnancy, pelvic adhesion, artificial abortion, operation, number of pregnancies and IUD are the independent risk factors, and pelvic adhesion is the major risk factor. Conclusion  Avoidance of unexpected pregnancy as possible, reduction of the number of artificial abortion, prevention and treatment of genital duct inflammation, and standardization of pelvic operation may reduce the incidence of ectopic pregnancy.

    Juvenile myelomonocytic leukemia (JMML) is a rare clonal myeloproliferative disorder of childhood. Major progress has been achieved in diagnosis and the understanding of the pathogenesis of JMML by identifying the genetic pathologies that occur in patients. Mutations of RAS, NF1, PTPN11, and CBL are found in approximately 80% of JMML patients. Distinct clinical features have been reported to be associated with specific gene mutations. The advent of genomic studies and recent identification of novel genetic mutations in JMML are important not only in diagnosis but also in the management and prognosis of the disease. Herein, we present 2 patients with JMML harboring different mutations, NRAS and c-CBL, respectively, with distinct clinical features and different therapeutic approaches.

    Full Text Available BACKGROUND: Scrub typhus is an infectious disease caused by Orientia tsutsugamushi. The differences in virulence of O. tsutsugamushi prototypes in humans are still unknown. We investigated whether there are any differences in the clinical features of the Boryoung and Karp genotypes. METHODOLOGY/PRINCIPAL FINDINGS: Patients infected with O. tsutsugamushi, as Boryoung and Karp clusters, who had visited 6 different hospitals in southwestern Korea were prospectively compared for clinical features, complications, laboratory parameters, and treatment responses. Infected patients in the Boryoung cluster had significantly more generalized weakness, eschars, skin rashes, conjunctival injection, high albumin levels, and greater ESR and fibrinogen levels compared to the Karp cluster. The treatment response to current antibiotics was significantly slower in the Karp cluster as compared to the Boryoung cluster. CONCLUSION: The frequency of occurrence of eschars and rashes may depend on the genotype of O. tsutsugamushi.

    Patients with Huntington's disease (HD) carrying CAG repeats beyond 60 are less frequently seen and clinical features of them have been rarely reported. We identified four unrelated patients carrying CAG repeats beyond 60 (84.0 ± 13.76, ranging from 74 to 104) from 119 Chinese HD patients via direct sequencing. These four were all early onset with a mean age at presenting symptom of 9.8 ± 1.71 years. Paternal transmission was found in three of them and the fourth was apparently sporadic. In addition, they had atypical onset symptoms including epilepsy, intellectual decline, tics and walking instability, which might lead the clinicians to make the wrong diagnosis in the early stage of disease. Our work explores clinical features of Chinese HD patients with an expanded CAG repeat over 60 and may help the clinicians make a correct diagnosis in the early stage of disease.

    We investigated the clinical features and gene mutation in a pedigree of spinocerebellar ataxia (SCA). A series of clinical tests was performed including visual examination, retinal angiography, visual evoked potential, electroretinogram and magnetic resonance imaging. Genomic DNA of the family members and normal controls was used for amplification of the (CAG)n repeats of SCA1, SCA2, SCA3, SCA6, SCA7, SCA17 and DRPLA genes by PCR. The number of (CAG)n was determined by 8% denaturing polyacrylamide gel electrophoresis and direct sequencing. The main features of 2 patients were ataxia, visual failure, retinal degeneration, cerebellar and pontine atrophy. A mutation in SCA7 gene was detected, while no mutations were found in SCA1, SCA2, SCA3, SCA6, SCA17 or DRPLA gene. Therefore, this is a pedigree of SCA7. Analysis of the CAG trinucleotide repeat expansion at the SCA7 locus can provide valuable insights into SCA7.

    A large percentage of dermatologist׳s decision in psoriasis disease assessment is based on color. The current computer-aided diagnosis systems for psoriasis risk stratification and classification lack the vigor of color paradigm. The paper presents an automated psoriasis computer-aided diagnosis (pCAD) system for classification of psoriasis skin images into psoriatic lesion and healthy skin, which solves the two major challenges: (i) fulfills the color feature requirements and (ii) selects the powerful dominant color features while retaining high classification accuracy. Fourteen color spaces are discovered for psoriasis disease analysis leading to 86 color features. The pCAD system is implemented in a support vector-based machine learning framework where the offline image data set is used for computing machine learning offline color machine learning parameters. These are then used for transformation of the online color features to predict the class labels for healthy vs. diseased cases. The above paradigm uses principal component analysis for color feature selection of dominant features, keeping the original color feature unaltered. Using the cross-validation protocol, the above machine learning protocol is compared against the standalone grayscale features with 60 features and against the combined grayscale and color feature set of 146. Using a fixed data size of 540 images with equal number of healthy and diseased, 10 fold cross-validation protocol, and SVM of polynomial kernel of type two, pCAD system shows an accuracy of 99.94% with sensitivity and specificity of 99.93% and 99.96%. Using a varying data size protocol, the mean classification accuracies for color, grayscale, and combined scenarios are: 92.85%, 93.83% and 93.99%, respectively. The reliability of the system in these three scenarios are: 94.42%, 97.39% and 96.00%, respectively. We conclude that pCAD system using color space alone is compatible to grayscale space or combined color and grayscale

    Full Text Available Background. We aimed to evaluate the efficacy of various diagnostic tools such as computerized tomography (CT, small bowel follow-through (SBFT, and capsule endoscopy (CE in diagnosing small bowel tumors (SBTs. Additionally, we aimed to evaluate the clinical features of SBTs missed by CE. Methods. We retrospectively studied 79 patients with histologically proven SBT. Clinical data were analyzed with particular attention to the efficacy of CT, SBFT, and CE in detecting SBT preoperatively. We also analyzed the clinical features of SBTs missed by CE. Results. The most common symptoms of SBT were bleeding (43% and abdominal pain (13.9%. Diagnostic yields were as follows: CT detected 55.8% of proven SBTs; SBFT, 46.1%; and CE, 83.3%. The sensitivity for detecting SBTs was 40.4% for CT, 43.9% for SBFT, and 79.6% for CE. Two patients with nondiagnostic but suspicious findings on CE and seven patients with negative findings on CE were eventually found to have SBT. These nine patients were eventually diagnosed with gastrointestinal stromal tumor (4, small polyps (3, inflammatory fibroid polyp (1, and adenocarcinoma (1. These tumors were located in the proximal jejunum (5, middle jejunum (1, distal jejunum (1, and proximal ileum (1. Conclusion. CE is more efficacious than CT or SBFT for detecting SBTs. However, significant tumors may go undetected with CE, particularly when located in the proximal jejunum.

    2005-01-01

    In order to improve diagnosis of schizophrenia with onset in adolescents at an early stage, we investigated in detail the clinical features of 74 patients with schizophrenia, (23 males) at adolescents psychiatric clinic. Many of the subjects had been suffering from the illness about 14 years old but had not undergone their first psychiatric examination until a few years later. A high percentage (more than 80%) of our subjects presented psychiatric symptoms such as delusional remembrance, delusional moods, delusions of persecution and hypobulia. Additionally, more than 60% of our subjects presented auditory hallucinations. In general, teenage patients with schizophrenia onset show vague symptoms such as anxiety, embarrassment and strange moods rather than obvious hallucinations. Nevertheless, it was possible to identify certain clinical features of this disorder in adolescents: many patients suffer delusional remembrance, delusional moods and delusions of persecution immediately after the onset of the illness. Gradually, problematic behaviors such as anorexia, self injury, offences against their families, voluntary vomiting, etc., develop, but patients do not always receive psychiatric examination at this stage. After socially obvious problems such as school refusal, withdrawal from social activities and lowering of school record develop over a period of time, patients may be urged to undergo psychiatric examination. Our research again underlines the difficulty of achieving diagnosis of schizophrenia at an early stage. The key to early diagnosis appears to be the accurate identification of psychiatric symptoms in the early stages of the illness at school, or at home if possible, before socially problematic behaviors arise.

    Full Text Available `INTRODUCTION: Stroke is the third leading cause of death in developed countries after cardiovascular disease and cancer. In India Community Surveys have shown a crude prevalence rate for hemiplegia 200 per 1, 00, 000 population. It accounts for nearly 1.5% of all urban admissions, 4.5 % of all medical and about 20% of neurological cases. AIMS AND OBJECTIVE: Identification of risk factors and evaluation of clinical profile of acute stroke. MATERIAL AND METHOD: INCLUSION CRITERIA: Cases of acute stoke admitted in SGMH hospital were selected for the study. EXCLUSION CRITERIA: Brain injury cases, infective, neoplastic cases producing stroke were excluded. RESULTS: Stroke was more common in male, 58 % patients were male and 42% patients were female. It was more common in 5th and 6th decade. Most common etiology was infarction. Most common risk factor was hypertension followed by smoking. In addition to limb weakness, headache and vomiting were most common presenting symptoms followed by convulsion. These symptoms were more common in hemorrhagic stroke. Right sided hemiplegia was more common than left sided. Middle cerebral artery was involved in majority of cases in atherothrombotic stroke whereas basal ganglion was most common site of bleed in hemorrhagic stroke. Coma and mortality were more in hemorrhagic stroke. CONCLUSION: The risk factors and clinical profile of acute stroke in India are similar to that of Western countries. Common risk factors are hypertension, smoking, diabetes mellitus and hyperlipidemia

    Hutchinson-Gilford progeria syndrome (HGPS) is a rare dysmorphic syndrome characterized by several features of premature aging with clinical involvement of the skin, bones, and cardiovascular system. HGPS has an estimated incidence of one in four million to one in eight million births. The main clinical features of HGPS include short stature, craniofacial dimorphism, alopecia, bone fragility, and cardiovascular disorders. The most frequent cause of death is myocardial infarction at a mean age of 13 years old. Dental manifestations include delayed development and eruption of teeth, discoloration, crowding and rotation of teeth, and displaced teeth. Cone beam computed tomography images revealed the absence of the sphenoid, frontal, and maxillary sinus, flattening of the condyles and glenoid fossa, and bilateral hypoplasia of the mandibular condyles. The disease is caused by mutations in lamin A/C (LMNA). Here, we present a case report of an 11-year-old boy with classical features of HGPS, which was caused by a de novo germ-line mutation (C1824T, G608G) in exon 11 of the LMNA gene. Some uncommon HGPS-associated features in our patient, such as alterations in the facial sinuses and hypoplasia of the condyles, contributed to the expansion of the phenotypic spectrum of this syndrome from a dentomaxillofacial perspective.

    Fractures during clinical function have been reported as the major concern associated with all-ceramic dental restorations. The aim of this study was to analyze the fracture features of glass-ceramic and zirconia-based restorations fractured during clinical use. Twenty-seven crowns and onlays were supplied by dentists and dental technicians with information about type of cement and time in function, if available. Fourteen lithium disilicate glass-ceramic restorations and 13 zirconia-based restorations were retrieved and analyzed. Fractographic features were examined using optical microscopy to determine crack initiation and crack propagation of the restorations. The material comprised fractured restorations from one canine, 10 incisors, four premolars, and 11 molars. One crown was not categorized because of difficulty in orientation of the fragments. The results revealed that all core and veneer fractures initiated in the cervical margin and usually from the approximal area close to the most coronally placed curvature of the margin. Three cases of occlusal chipping were found. The margin of dental all-ceramic single-tooth restorations was the area of fracture origin. The fracture features were similar for zirconia, glass-ceramic, and alumina single-tooth restorations. Design features seem to be of great importance for fracture initiation.

    Full Text Available Objective Patients with drug-induced parkinsonism (DIP may have nigrostriatal dopaminergic degeneration. We studied the clinical features that may indicate nigrostriatal dopaminergic degeneration in patients with DIP. Methods Forty-one DIP patients were classified into normal and abnormal [18F] FP-CIT scan groups. Differences in 32 clinical features and drug withdrawal effects were studied. Results Twenty-eight patients had normal (Group I and 13 patients had abnormal (Group II scans. Eight patients of Group I, but none of Group II, had taken calcium channel blockers (p = 0.040. Three patients of Group I and six of Group II had hyposmia (p = 0.018. After drug withdrawal, Group I showed greater improvement in Unified Parkinson’s Disease Rating Scale total motor scores and subscores for bradykinesia and tremors than Group II. Only hyposmia was an independent factor associated with abnormal scans, but it had suboptimal sensitivity. Conclusion None of the clinical features were practical indicators of nigrostriatal dopaminergic degeneration in patients with DIP.

    Objective. To describe the clinical, radiological and MRI features of six atypical cases of histologically proven appendicular Ewing sarcoma/ primitive neuroectodermal tumour (PNET). Design. Retrospective review of case notes and available imaging was carried out. Patients. Six patients (4 male, 2 female; mean age 27 years, range 19-44 years), presenting over a 77-month period, were identified from the Bone Tumour Register. All had unusual clinical and imaging features for Ewing sarcoma/PNET.Results and conclusions. Four tumours were centred on the distal femoral metaphysis, one in the proximal tibial metaphysis and one in the distal tibial metaphysis. Plain radiographs were available in four cases and showed minor cortical changes. MRI demonstrated a relatively small, eccentrically located intraosseous component with a large, eccentric extraosseous component. Extension into the epiphysis was seen in three cases and into the adjacent joint in two cases. Intraosseous ''skip'' metastases were present in three cases. The clinical and imaging features were atypical for conventional intraosseous Ewing sarcoma/PNET and the exact site of origin (intraosseous, periosteal or soft-tissue) was unclear. (orig.)

    Solitary rectal ulcer syndrome (SRUS) is an uncommon benign disease, characterized by a combination of symptoms, clinical findings and histological abnormalities. Ulcers are only found in 40% of the patients; 20% of the patients have a solitary ulcer, and the rest of the lesions vary in shape and size, from hyperemic mucosa to broad-based polypoid. Men and women are affected equally, with a small predominance in women. SRUS has also been described in children and in the geriatric population. Clinical features include rectal bleeding, copious mucus discharge, prolonged excessive straining, perineal and abdominal pain, feeling of incomplete defecation, constipation, and rarely, rectal prolapse. This disease has well-described histopathological features such as obliteration of the lamina propria by fibrosis and smooth muscle fibers extending from a thickened muscularis mucosa to the lumen. Diffuse collage deposition in the lamina propria and abnormal smooth muscle fiber extensions are sensitive markers for differentiating SRUS from other conditions. However, the etiology remains obscure, and the condition is frequently associated with pelvic floor disorders. SRUS is difficult to treat, and various treatment strategies have been advocated, ranging from conservative management to a variety of surgical procedures. The aim of the present review is to summarize the clinical features, pathophysiology, diagnostic methods and treatment strategies associated with SRUS.

    Full Text Available Abstract Background Craniocervical arterial dissection is a major cause of ischaemic stroke in young adults. The pathogenesis is not fully understood but is thought to be related to a combination of an intrinsic weakness in the arterial wall and an external trigger. Intrinsic susceptibility is thought to be a generalised arteriopathy, vascular anomaly or genetic predisposition. Proposed extrinsic factors include recent viral infection and minor mechanical trauma to the neck, including neck manipulation, which has raised concerns amongst manual practitioners in particular as to the appropriate screening of patients and avoidance of more vigorous therapeutic techniques. The presenting features of dissection may mimic a musculoskeletal presentation, creating a diagnostic dilemma for primary care practitioners. Early recognition is critical so that appropriate management can be commenced. The aims of this study are to prospectively investigate young patients ≤55 years admitted to hospital with radiologically diagnosed craniocervical arterial dissection compared to matched controls with stroke but not dissection, to identify risk factors and early presenting clinical features, so these may be more readily identified by primary care practitioners. Methods Patients ≤ 55 years presenting to hospital with craniocervical arterial dissection and controls will have their medical records reviewed and be interviewed and questioned about possible risk factors, preceding events to admission such as recent neck trauma, and presenting clinical features including any preceding transient ischaemic features. Clinical assessment will include a connective tissue screening examination to identify subclinical connective tissue disorders. Radiology and blood screening will be reviewed for typical features and inflammatory markers. Functional outcome will be reviewed to determine the burden of the stroke. Discussion This study will provide descriptive and

    Introduction To improve our understanding of sex differences in the clinical characteristics of Parkinson’s Disease, we sought to examine differences in the clinical features and disease severity of men and women with early treated Parkinson’s Disease (PD) enrolled in a large-scale clinical trial. Methods Analysis was performed of baseline data from the National Institutes of Health Exploratory Trials in Parkinson’s Disease (NET-PD) Long-term Study-1, a randomized, multi-center, double-blind, placebo-controlled study of 10 grams of oral creatine/day in individuals with early, treated PD. We compared mean age at symptom onset, age at PD diagnosis, and age at randomization between men and women using t-test statistics. Sex differences in clinical features were evaluated, including: symptoms at diagnosis (motor) and symptoms at randomization (motor, non-motor, and daily functioning). Results 1,741 participants were enrolled (62.5% male). No differences were detected in mean age at PD onset, age at PD diagnosis, age at randomization, motor symptoms, or daily functioning between men and women. Differences in non-motor symptoms were observed, with women demonstrating better performance compared to men on SCOPA-COG (Z = 5.064, p<0.0001) and Symbol Digit Modality measures (Z = 5.221, p<0.0001). Conclusions Overall, men and women did not demonstrate differences in clinical motor features early in the course of PD. However, the differences observed in non-motor cognitive symptoms suggests further assessment of the influence of sex on non-motor symptoms in later stages of PD is warranted. PMID:26171861

    Full Text Available Objective To investigate the onset pattern, clinical manifestations, laboratory findings and imaging features of 17 Chinese patients with steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT. Methods The clinical data of 17 SREAT patients were collected. Retrospective analysis of their clinical features, as well as their serum levels of anti-thyroid, cerebrospinal fluid (CSF biochemical indicators, MRI and therapy was performed. Results The initial symptoms of those patients were seizures (4 cases, psychiatric symptoms (4 cases, hypomnesis (4 cases, walking unsteadiness (2 cases, headache (2 cases and dysarthria (1 case. Three cases were acute onset, 5 cases subacute onset and 9 cases chronic onset. The anti-thyroid peroxidase antibody (anti-TPO of 17 cases were significantly increased, average (928.63 ± 406.28 × 10 3 IU/L. The anti?thyroglobulin antibody (anti-TG of 15 cases was increased, average (601.27 ± 1014.12 × 10 3 IU/L. The protein in CSF was mildly increased, average (513.75 ± 283.15 mg/L. The EEG of 5 patients presented slow wave and the EEG of 2 patients showed epileptiform discharge. The brain MRI of 11 patients showed multifocal lesions in frontal lobe, temporal lobe, parietal lobe, basal ganglia, centrum ovale, corpus callosum, thalamus, cerebellum, and brain stem. The findings of clinical immunological index and tumor markers were normal. Besides, the prognosis of 11 patients treated with methylprednisolone and 3 patients treated with dexamethasone were good. Recurrence occurred in 2 patients. Conclusion Basically, the clinical features of Chinese SREAT patients present seizures, hypomnesis and psychiatric symptoms associated with increased anti-thyroid and multifocal lesions in gray and white matter of brain.

    Breast cancer risk assessment can inform the use of screening and prevention modalities. We investigated the performance of the Breast Cancer Surveillance Consortium (BCSC) risk model in combination with a polygenic risk score (PRS) comprised of 83 single nucleotide polymorphisms identified from genome-wide association studies. We conducted a nested case-control study of 486 cases and 495 matched controls within a screening cohort. The PRS was calculated using a Bayesian approach. The contributions of the PRS and variables in the BCSC model to breast cancer risk were tested using conditional logistic regression. Discriminatory accuracy of the models was compared using the area under the receiver operating characteristic curve (AUROC). Increasing quartiles of the PRS were positively associated with breast cancer risk, with OR 2.54 (95 % CI 1.69-3.82) for breast cancer in the highest versus lowest quartile. In a multivariable model, the PRS, family history, and breast density remained strong risk factors. The AUROC of the PRS was 0.60 (95 % CI 0.57-0.64), and an Asian-specific PRS had AUROC 0.64 (95 % CI 0.53-0.74). A combined model including the BCSC risk factors and PRS had better discrimination than the BCSC model (AUROC 0.65 versus 0.62, p = 0.01). The BCSC-PRS model classified 18 % of cases as high-risk (5-year risk ≥3 %), compared with 7 % using the BCSC model. The PRS improved discrimination of the BCSC risk model and classified more cases as high-risk. Further consideration of the PRS's role in decision-making around screening and prevention strategies is merited.

    Full Text Available Aim: To evaluate the morphological and hemodynamic changes that take place in carotid arteries by colour Doppler in patients presenting with features of stroke. Background and Objectives: Cerebrovascular accidents constitute a major cause of adult mortality. The principal indication for cerebrovascular Doppler examination is stroke prevention. Colour Doppler sonography is a sensitive method for detection of atherosclerotic plaque and provides considerable information about the extent and severity of plaque as well as the resulting diminution of arterial lumen. The main strengths of sonography of carotid arteries are patient comfort, lack of risk and accuracy in detecting carotid stenosis. Material and Methods: A prospective study of Colour Doppler in carotid arteries was carried out for 12 months from 1 st July 2009 to 1 st July 2010. The study was carried out on 40 individuals, suspected of cerebrovascular insufficiency and having one or the other risk factors for cerebrovascular disease. A detailed clinical history, CNS examination findings and evidence of hypertension, diabetes mellitus, hyperlipidemia and ischemic heart disease were noted. Carotid Doppler evaluation was done by using Siemens Antares Ultrasound system. The data gathered were grey scale and Doppler findings of common carotid artery, internal carotid artery and external carotid arteries. Doppler findings were correlated with clinical features and risk factors. Results: In our study of 40 patients, the commonest lesion found was the atherosclerotic plaque. Highest incidence of plaque was seen in males 41% in the age group of 60-70 years and in females 37% in age group of 70-80 years. Cigarette smoking was the most common risk factor (60% associated with stroke/ Transient Ischaemic Attacks (TIA. Hemiparesis was the most common presenting symptom (35% among the symptomatic cases. Atheromatous plaque was most commonly found in the right carotid system (60%. Most common site for

    Pressures associated with flooding and climate change have significantly increased over recent years. Natural Flood Risk Management (NFRM) is now seen as being a more appropriate and favourable approach in some locations. At the same time, catchment managers are also encouraged to adopt a more integrated, evidence-based and bottom-up approach. This includes engaging with local communities. Although NFRM features are being more readily installed, there is still limited evidence associated with their ability to reduce flood risk and offer multiple benefits. In particular, local communities and land owners are still uncertain about what the features entail and how they will perform, which is a huge barrier affecting widespread uptake. Traditional hydrometric monitoring techniques are well established but they still struggle to successfully monitor and capture NFRM performance spatially and temporally in a visual and more meaningful way for those directly affected on the ground. Two UK-based case studies are presented here where unique NFRM features have been carefully designed and installed in rural headwater catchments. This includes a 1km2 sub-catchment of the Haltwhistle Burn (northern England) and a 2km2 sub-catchment of Eddleston Water (southern Scotland). Both of these pilot sites are subject to prolonged flooding in winter and flash flooding in summer. This exacerbates sediment, debris and water quality issues downstream. Examples of NFRM features include ponds, woody debris and a log feature inspired by the children's game 'Kerplunk'. They have been tested and monitored over the 2015-2016 winter storms using low-cost techniques by both researchers and members of the community ('citizen scientists'). Results show that monitoring techniques such as regular consumer specification time-lapse cameras, photographs, videos and 'kite-cams' are suitable for long-term and low-cost monitoring of a variety of NFRM features. These techniques have been compared against

    Full Text Available Non-alcoholic steatohepatitis (NASH is a disease of unknown origin characterized histologically by alcoholic-like liver injury in the absence in the absence of significant alcohol intake. This study was conducted to assess the clinical and pathological features of NASH patients in Iran. Patients with elevated liver transaminases, negative serologic markers of viral or autoimmune hepatitis and no findings in favor of metabolic liver disease were enrolled. A careful history was taken with special attention to alcohol intake and ultrasonography and liver biopsy were performed in those with no evidence of significant alcohol intake. A histology showing moderate to gross macrovesicular fatty change with inflammation (lobular or portal, with or without Mallory bodies, fibrosis, or cirrhosis, was considered diagnostic for NASH. Patients with mild steatosis were rechecked for the presence of hepatitis C virus (HCV infection. Fifty-three patients who met the above criteria entered the study. Thirty-two patients (60.4% were male and 21 (39.6% were female with the mean age of 37.8±11.3 years. Twenty-six patients (55.3% were diabetic. Mean AST to ALT ratio was 0.95±0.52; 65.3%of patients had a ratio below than 1, and 95.9% were below of 2. Ultrasonography was abnormal in 32 (76.2% patients. Liver biopsy showed mild steatosis in 35.7% moderate steatosis in 53.6% and severe forms in 10.7%. In 80.2% of patients, portal inflammation was present, and 15.1% had some degrees of fibrosis. The amount of increase in liver enzymes bore no relationship with the presence of fibrosis, portal inflammation, and degree of steatosis (P>0.05. The patients wee somewhat younger than other studies, and most of them were male which might be due to the low rate of alcohol consumption in our country. Most of the patients had body mass index (BMI higher than normal. Our findings show that NASH must not be considered a disease confined to high-risk groups only, and its impact be

    Full Text Available Influenza virus causes mild-to-severe acute respiratory illness. H1N1 bronchopneumonia carries a higher mortality. MATERIALS AND METHODS Study was a prospective observational study conducted in a 24 bedded multidisciplinary ICU from January 2010 to December 2010. We included all adult patients admitted to our intensive care unit presenting with clinical features/suspicion of H1N1 bronchopneumonia and respiratory failure. These patients also subsequently tested positive for H1N1 Reverse-Transcriptase Polymerase Chain Reaction (RT-PCR assay. Data was collected on demography, co-morbid illness, APACHE II and SOFA scores, organ failure and support. Outcome data on mortality, ICU LOS and ventilator days was also collected. RESULTS 28 patients with H1N1 bronchopneumonia required intensive care treatment. Majority of patients were females 60.7 % (n=17; of these 17 patients 7 patients were pregnant. Mean age of our patients was 50.6 (±19.1 years. Most common co-existing illnesses were diabetes mellitus (32.1% and hypertension (32.1% followed by bronchial asthma (10.7%; 85.7% patients had at least one organ dysfunction on admission, of which respiratory system was involved in 96.5% followed by renal system 57.1%. Patients were sick on admission as indicated by high APACHE II (17.75±6.5 and SOFA (5.25±1.8 scores. Mean PaO2/FiO2 on admission was 148.9±77.2. Severe ARDS (PaO2/FiO2 <100 was seen in 39.35% of patients. Of the 28 patients, 27 patients required ventilator support; 17 patients died out of 28 patients (mortality rate 60.7%. Higher APACHE II, SOFA scores and low PaO2/FiO2 on admission were identified as significant risk factors for mortality. CONCLUSION Critically ill H1N1 pneumonia patients present with multisystem involvement and they had a high mortality in our study.

    Vibrio parahaemolyticus is a bacterial pathogen that can cause illness after the consumption or handling of contaminated seafood. The primary virulence factors associated with V. parahaemolyticus illness are thermostable direct hemolysin (TDH) and Tdh-related hemolysin (TRH). However, clinical strains lacking tdh and trh have recently been isolated, and these clinical isolates are poorly understood. To help understand the emergence of clinical tdh- and trh-negative isolates, a genomic approach was used to comprehensively compare 4 clinical tdh- and trh-negative isolates with 16 environmental tdh- and trh-negative isolates and 34 clinical isolates positive for tdh or trh, or both, with the objective of identifying genomic features that are unique to clinical tdh- and trh-negative isolates. The prevalence of pathogenicity islands (PAIs) common to clinical isolates was thoroughly examined in each of the clinical tdh- and trh-negative isolates. The tdh PAI was not present in any clinical or environmental tdh- and trh-negative isolates. The trh PAI was not present in any environmental isolates; however, in clinical tdh- and trh-negative isolate 10-4238, the majority of the trh PAI including a partial trh1 gene was present, which resulted in reclassification of this isolate as a tdh-negative and trh-positive isolate. In the other clinical tdh- and trh-negative isolates, neither the trh gene nor the trh PAI was present. We identified 862 genes in clinical tdh- and trh-negative isolates but not in environmental tdh- and trh-negative isolates. Many of these genes are highly homologous to genes found in common enteric bacteria and included genes encoding a number of chemotaxis proteins and a novel putative type VI secretion system (T6SS) effector and immunity protein (T6SS1). The availability of genome sequences from clinical V. parahaemolyticus tdh- and trh-negative isolates and the comparative analysis may help provide an understanding of how this pathotype is able to

    Our objective was to identify the main clinical and epidemiological features of ALS in a large cohort of African American (AA) patients and compare them to Caucasian (CA) patients in a clinic-based population. We retrospectively identified 207 patients who were diagnosed with ALS based on the revised El Escorial criteria (60 AA and 147 CA subjects). Patients were seen in the Neuromuscular Division at the University Medical Center. We compared epidemiological and clinical features of these two groups, focusing on age of onset and diagnosis, clinical presentation and survival. Results showed that AA patients had a significantly younger age of disease onset (55 years vs. 61 years for CA, p = 0.011) and were diagnosed at an earlier age (56 years vs. 62 years, p = 0.012). In younger ALS patients (population and males in the CA population (p = 0.025). In a multivariable Cox proportional hazard model, survival rates were not different between the groups. In both groups, survival significantly increased with younger age. In conclusion, AA patients presented at an earlier age, but there was no difference in survival compared to CA patients. A gender reversal occurred in younger ALS patients, with AA patients more likely to be female and CA patients more likely to be male.

    SUMMARY Contemporary clinical assessment of back pain is based on the diagnostic triage paradigm. The most common diagnostic classification is nonspecific back pain, considered to be of nociceptive etiology. A small proportion are diagnosed with radicular pain, of neuropathic origin. In this study we review the body of literature on the prevalence of neuropathic features of back pain, revealing that the point prevalence is 17% in primary care, 34% in mixed clinical settings and 53% in tertiary care. There is evidence that neuropathic features of back pain are not restricted to typical clinical radicular pain phenotypes and may be under-recognized, particularly in primary care. The consequence of this is that in the clinic, diagnostic triage may erroneously classify patients with nonspecific back pain or radicular pain. A promising alternative is the development of mechanism-based pain phenotyping in patients with back pain. Timely identification of contributory pain mechanisms may enable greater opportunity to select appropriate therapeutic targets and improve patient outcomes.

    Critical appraisal of the literature highlights that the discriminative power of gait-related features in patients with hip osteoarthritis (OA) has not been fully explored. We aimed to reduce the number of gait-related features and define the most discriminative ones comparing the three-dimensional gait analysis of 20 patients with hip osteoarthritis (OA) with those of 17 healthy peers. First, principal component analysis was used to reduce the high-dimensional gait data into a reduced set of interpretable variables for further analysis, including tests for group differences. These differences were indicative for the selection of the top 10 variables to be included into linear discriminant analysis models (LDA). Our findings demonstrated the successful data reduction of hip osteoarthritic-related gait features with a high discriminatory power. The combination of the top variables into LDA models clearly separated groups, with a maximum misclassification error rate of 19%, estimated by cross-validation. Decreased hip/knee extension, hip flexion and internal rotation moment were gait features with the highest discriminatory power. This study listed the most clinically relevant gait features characteristics of hip OA. Moreover, it will help clinicians and physiotherapists understand the movement pathomechanics related to hip OA useful in the management and design of rehabilitation intervention.

    Full Text Available Lichen planus pemphigoides (LPP is a rare, acquired and autoimmune disorder. LPP clinically, histologically and immunologically appears to be a combination of lichen planus and bullous pemphigoides. LPP is usually idiopathic but some cases have been associated with drugs, phototherapy, infections and malignancy. It has different clinical variants such as presenting with only oral lesions; with oral and cutaneous lesions and with only cutaneous lesions, respectively. We present two cases with typical histologic and immunofluorescence features of LPP. Our 55 years old male case had typical lichen planus lesions with widespread bulla and erosions; he responded systemic steroid treatment in a short time. Bulla and erosions were not prominent in our 16 years old female case and with topical treatments to her lesions improved in a short time. LPP should be considered in the clinical differential diagnosis of vesiculoerosive oral mucosal and cutaneous diseases.

    Mycosis fungoides (MF) simulates a variety of dermatologic disorders histopathologically and clinically, well deserving the designation of a great mimicker. Interstitial MF is a rare, but well-recognized histopathological variant resembling the interstitial form of granuloma annulare or the inflammatory phase of morphea. From a clinical standpoint, MF can have a wide array of manifestations, including an anecdotal presentation with lesions clinically suggestive of lichen sclerosus (LS). We herein report a 25-year-old man with a history of patch-stage MF who later developed widespread LS-like lesions histopathologically consistent with interstitial MF. In some biopsies, additional features resembling LS were discerned. We think that our case might represent a unique variant of interstitial MF presenting with LS-like lesions. The diagnostic challenge arising from this uncommon presentation is discussed together with review of the literature.

    Full Text Available The author studied in detail the specific features of the clinical manifestations reflecting a granulomatous inflammatory response and necrotizing polyangiitis, by using her experience in following up 70 patients with granulomatosis and polyangiitis (Wegener's, and analyzed their early symptoms, premorbid background, and possible predictors. Granulomatous inflammation and its related clinical manifestations (primarily orbital pseudotumor and subfold granuloma of the larynx was demonstrated to tend over time to occupy a dominant place in the clinical picture of the disease while the proportion of the symptoms apparently related to necrotizing vasculitis was generally decreased. Interpretation of mechanisms for the development of granulomatosis with polyangiitis (Wegener's may be of value for the further elaboration of an optimal treatment strategy.

    Full Text Available We explore how avatars can be used as social orthotics defined as therapeutic computer-based social companions aimed at promoting healthy behaviors. We review some of the health interventions deployed in helping at-risk populations along with some of the unique advantages that computer-based interventions can add to face-to-face interventions. We posit that artificial intelligence has rendered possible the creation of culturally appropriate dialog-agents for interventions and we identify specific features for social avatars that are important - if not necessary - when applied to the domain of social orthotic systems for health promotion.

    A novel breast cancer risk analysis approach is proposed for enhancing performance of computerized breast cancer risk analysis using bilateral mammograms. Based on the intensity of breast area, five different sub-regions were acquired from one mammogram, and bilateral features were extracted from every sub-region. Our dataset includes 180 bilateral mammograms from 180 women who underwent routine screening examinations, all interpreted as negative and not recalled by the radiologists during the original screening procedures. A computerized breast cancer risk analysis scheme using four image processing modules, including sub-region segmentation, bilateral feature extraction, feature selection, and classification was designed to detect and compute image feature asymmetry between the left and right breasts imaged on the mammograms. The highest computed area under the curve (AUC) is 0.763 ± 0.021 when applying the multiple sub-region features to our testing dataset. The positive predictive value and the negative predictive value were 0.60 and 0.73, respectively. The study demonstrates that (1) features extracted from multiple sub-regions can improve the performance of our scheme compared to using features from whole breast area only; (2) a classifier using asymmetry bilateral features can effectively predict breast cancer risk; (3) incorporating texture and morphological features with density features can boost the classification accuracy.

    In order to establish a personalized breast cancer screening program, it is important to develop risk models that have high discriminatory power in predicting the likelihood of a woman developing an imaging detectable breast cancer in near-term (e.g., breast cancer risk models, mammographic density is considered the second highest breast cancer risk factor (second to woman's age). In this study we explored a new feature, namely bilateral mammographic density asymmetry, and investigated the feasibility of predicting near-term screening outcome. The database consisted of 343 negative examinations, of which 187 depicted cancers that were detected during the subsequent screening examination and 155 that remained negative. We computed the average pixel value of the segmented breast areas depicted on each cranio-caudal view of the initial negative examinations. We then computed the mean and difference mammographic density for paired bilateral images. Using woman's age, subjectively rated density (BIRADS), and computed mammographic density related features we compared classification performance in estimating the likelihood of detecting cancer during the subsequent examination using areas under the ROC curves (AUC). The AUCs were 0.63+/-0.03, 0.54+/-0.04, 0.57+/-0.03, 0.68+/-0.03 when using woman's age, BIRADS rating, computed mean density and difference in computed bilateral mammographic density, respectively. Performance increased to 0.62+/-0.03 and 0.72+/-0.03 when we fused mean and difference in density with woman's age. The results suggest that, in this study, bilateral mammographic tissue density is a significantly stronger (p<0.01) risk indicator than both woman's age and mean breast density.

    Wenqing Wu

    Full Text Available BACKGROUND: Dysthymia is a form of chronic mild depression that has a complex relationship with major depressive disorder (MDD. Here we investigate the role of environmental risk factors, including stressful life events and parenting style, in patients with both MDD and dysthymia. We ask whether these risk factors act in the same way in MDD with and without dysthymia. RESULTS: We examined the clinical features in 5,950 Han Chinese women with MDD between 30-60 years of age across China. We confirmed earlier results by replicating prior analyses in 3,950 new MDD cases. There were no significant differences between the two data sets. We identified sixteen stressful life events that significantly increase the risk of dysthymia, given the presence of MDD. Low parental warmth, from either mother or father, increases the risk of dysthymia. Highly threatening but short-lived threats (such as rape are more specific for MDD than dysthymia. While for MDD more severe life events show the largest odds ratio versus controls, this was not seen for cases of MDD with or without dysthymia. CONCLUSIONS: There are increased rates of stressful life events in MDD with dysthymia, but the impact of life events on susceptibility to dysthymia with MDD differs from that seen for MDD alone. The pattern does not fit a simple dose-response relationship, suggesting that there are moderating factors involved in the relationship between environmental precipitants and the onset of dysthymia. It is possible that severe life events in childhood events index a general susceptibility to chronic depression, rather than acting specifically as risk factors for dysthymia.

    BACKGROUND: Diagnosing pericardial effusion is critical for optimal patient care. Typically, clinicians use physical examination findings and historical features suggesting pericardial effusion to determine which patients require echocardiography. The diagnostic characteristics of these tools are not well described. The objective of this study is to determine the prevalence of historical features and sensitivity of clinical signs to inform clinicians when to proceed with echocardiogram. METHODS: A retrospective review of point-of-care echocardiograms performed over a two and a half year period in two emergency departments were reviewed for the presence of a pericardial effusion. Patient charts were reviewed and abstracted for presenting symptoms, historical features and clinical findings. The prevalence of presenting symptoms and historical features and the sensitivity of classic physical examination findings associated with pericardial effusion and tamponade were determined. RESULTS: One hundred and fifty-three patients with pericardial effusion were identified. Of these patients, the most common presenting complaint was chest pain and shortness of breath. Patients had no historical features that would suggest pericardial effusion in 37.5% of cases. None of the patients with pericardial effusion or pericardial tamponade had all of the elements of Beck’s triad. The sensitivity of Beck’s triad was found to be 0 (0%–19.4%). The sensitivity for one finding of Beck’s triad to diagnose pericardial tamponade was 50% (28.0%–72.0%). CONCLUSION: History and physical examination findings perform poorly as tests for the diagnosis of pericardial effusion or pericardial tamponade. Clinicians must liberally evaluate patients suspected of having a pericardial effusion with echocardiography. PMID:28123617

    Background: Skin infections caused by coryneform bacteria are common dermatological conditions. However, to the best of our knowledge, no studies are available on the clinical characteristics and epidemiological features of this group of disorders as one entity from India and abroad. Aims: To study the clinical and epidemiological features of coryneform skin infections Methods: A total of 75 patients presenting with clinically distinctive lesions of pitted keratolysis, erythrasma and trichobacteriosis to our hospital were included in the study. Cases were interviewed with particular emphasis on epidemiological features and the various clinical findings were recorded. Investigations like Gram's stain, Wood's light examination, 10% KOH scrapings, were done in selected cases to ascertain the diagnosis. Results: Pitted keratolysis was more common in the age group of 31-40 years (40%) with a male preponderance (76.7%), most commonly affecting pressure bearing areas of the soles with malodour (86.7%) and frequent contact with water (58.3%) constituting the most important presenting symptom and provocating factor respectively. Erythrasma affected both male and female patients equally and was more commonly detected in patients with a BMI > 23kg/m2 (62.5%) and in diabetics (50%). All patients with trichobacteriosis presented with yellow coloured concretions in the axillae. Bromhidrosis (71.4%) and failure to regularly use an axillary deodorant (71.4%) were the most common presenting symptom and predisposing factor respectively. Conclusion: Coryneform skin infections are common dermatological conditions, though epidemiological data are fragmentary. Hyperhidrosis is a common predisposing factor to all three coryneform skin infections. Asymmetrical distribution of pits has been reported in our study. Diabetic status needs to be evaluated in all patients with erythrasma. Woods lamp examination forms an indispensible tool to diagnose erythrasma and trichobacteriosis. PMID

    Rheumatoid arthritis (RA) is a chronic autoimmune rheumatic disease that can cause painful swelling in the joint lining, morning stiffness, and joint deformation/destruction. These symptoms decrease both quality of life and life expectancy. However, if RA can be diagnosed in the early stages, it can be controlled with pharmacotherapy. Although many studies have examined the possibility of early assessment and diagnosis, few have considered the relationship between significant risk factors and the early assessment of RA. In this paper, we present a novel framework for early RA assessment that utilizes data preprocessing, risk pattern mining, validation, and analysis. Under our proposed framework, two risk patterns can be discovered. Type I refers to well-known risk patterns that have been identified by existing studies, whereas Type II denotes unknown relationship risk patterns that have rarely or never been reported in the literature. These Type II patterns are very valuable in supporting novel hypotheses in clinical trials of RA, and constitute the main contribution of this work. To ensure the robustness of our experimental evaluation, we use a nationwide clinical database containing information on 1,314 RA-diagnosed patients over a 12-year follow-up period (1997-2008) and 965,279 non-RA patients. Our proposed framework is employed on this large-scale population-based dataset, and is shown to effectively discover rich RA risk patterns. These patterns may assist physicians in patient assessment, and enhance opportunities for early detection of RA. The proposed framework is broadly applicable to the mining of risk patterns for major disease assessments. This enables the identification of early risk patterns that are significantly associated with a target disease.

    Full Text Available Peroxisomal disorders are a group of genetically heterogeneous metabolic diseases related to dysfunction of peroxisomes. Dysmorphic features, neurological abnormalities, and hepatic dysfunction can be presenting signs of peroxisomal disorders. Here we presented dysmorphic facial features and other clinical characteristics in two patients with PEX1 gene mutation. Follow-up periods were 3.5 years and 1 year in the patients. Case I was one-year-old girl that presented with neurodevelopmental delay, hepatomegaly, bilateral hearing loss, and visual problems. Ophthalmologic examination suggested septooptic dysplasia. Cranial magnetic resonance imaging (MRI showed nonspecific gliosis at subcortical and periventricular deep white matter. Case II was 2.5-year-old girl referred for investigation of global developmental delay and elevated liver enzymes. Ophthalmologic examination findings were consistent with bilateral nystagmus and retinitis pigmentosa. Cranial MRI was normal. Dysmorphic facial features including broad nasal root, low set ears, downward slanting eyes, downward slanting eyebrows, and epichantal folds were common findings in two patients. Molecular genetic analysis indicated homozygous novel IVS1-2A>G mutation in Case I and homozygous p.G843D (c.2528G>A mutation in Case II in the PEX1 gene. Clinical findings and developmental prognosis vary in PEX1 gene mutation. Kabuki-like phenotype associated with liver pathology may indicate Zellweger spectrum disorders (ZSD.

    Full Text Available Objectives:  To study the clinical features and diagnostic value of CT in Fahr’s disease. Methods:  We retrospectively analyzed skull images of 8,000 cases and observed the incidence and imaging characteristics of Fahr’s disease. Results: Fahr’s disease were found in 6 patients (6/4000=0.075%whose ages ranged from 16 to 62 years (average age:38.5±6.4years. We found that 6 Fahr’s disease had been incidentally detected in 4 men(4/6=66.7% and 2 women(2/6=33.4%; serum calcium:2.13~2.42 mmol/L,serum phosphor:1.0~1.6 mmol/L.The most common CT feature of Fahr’s disease is the presence of small bilateral intracranial calcifications which are usually restricted to the bilateral globus pallidus, putamen, caudate nucleus, thalamus, dentate nucleus and white matter of the cerebral hemispheres. Conclusions: Combined with clinical manifestations and imaging features, we can make a clear diagnosis of the Fahr’s disease.

  17. Risk, diagnostic error, and the clinical science of consciousness

    Full Text Available In recent years, a number of new neuroimaging techniques have detected covert awareness in some patients previously thought to be in a vegetative state/unresponsive wakefulness syndrome. This raises worries for patients, families, and physicians, as it indicates that the existing diagnostic error rate in this patient group is higher than assumed. Recent research on a subset of these techniques, called active paradigms, suggests that false positive and false negative findings may result from applying different statistical methods to patient data. Due to the nature of this research, these errors may be unavoidable, and may draw into question the use of active paradigms in the clinical setting. We argue that false positive and false negative findings carry particular moral risks, which may bear on investigators' decisions to use certain methods when independent means for estimating their clinical utility are absent. We review and critically analyze this methodological problem as it relates to both fMRI and EEG active paradigms. We conclude by drawing attention to three common clinical scenarios where the risk of diagnostic error may be most pronounced in this patient group.

    Asthma is a heterogeneous disease with many phenotypes, and age at disease onset is an important factor in separating the phenotypes. Most studies with asthma have been performed in patients being otherwise healthy. However, in real life, comorbid diseases are very common in adult patients. We review here the emerging comorbid conditions to asthma such as obesity, metabolic syndrome, diabetes mellitus type 2 (DM2), and cardiac and psychiatric diseases. Their role as risk factors for incident asthma and whether they affect clinical asthma are evaluated. Obesity, independently or as a part of metabolic syndrome, DM2, and depression are risk factors for incident asthma. In contrast, the effects of comorbidities on clinical asthma are less well-known and mostly studies are lacking. Cross-sectional studies in obese asthmatics suggest that they may have less well controlled asthma and worse lung function. However, no long-term clinical follow-up studies with these comorbidities and asthma were identified. These emerging comorbidities often occur in the same multimorbid adult patient and may have in common metabolic pathways and inflammatory or other alterations such as early life exposures, systemic inflammation, inflammasome, adipokines, hyperglycemia, hyperinsulinemia, lung mechanics, mitochondrial dysfunction, disturbed nitric oxide metabolism, and leukotrienes.

    Objective: To test the hypothesis that core and suggestive features in possible dementia with Lewy bodies (DLB) would vary in their ability to predict an abnormal dopamine transporter scan and therefore a follow-up diagnosis of probable DLB. A further objective was to assess the evolution of core and suggestive features in patients with possible DLB over time depending on the 123I-FP-CIT SPECT scan result. Methods: A total of 187 patients with possible DLB (dementia plus one core or one suggestive feature) were randomized to have dopamine transporter imaging or to follow-up without scan. DLB features were compared at baseline and at 6-month follow-up according to imaging results and follow-up diagnosis. Results: For the whole cohort, the baseline frequency of parkinsonism was 30%, fluctuations 29%, visual hallucinations 24%, and REM sleep behavior disorder 17%. Clinician-rated presence of parkinsonism at baseline was significantly (p = 0.001) more frequent and Unified Parkinson’s Disease Rating Scale (UPDRS) score at baseline was significantly higher (p = 0.02) in patients with abnormal imaging. There was a significant increase in UPDRS score in the abnormal scan group over time (p < 0.01). There was relatively little evolution of the rest of the DLB features regardless of the imaging result. Conclusions: In patients with possible DLB, apart from UPDRS score, there was no difference in the evolution of DLB clinical features over 6 months between cases with normal and abnormal imaging. Only parkinsonism and dopamine transporter imaging helped to differentiate DLB from non-DLB dementia. PMID:27511183

    The erysipeloid form of cutaneous leishmaniasis is considered as an unusual and rare clinical presentation in Tunisia. Our prospective study on 4 observations, aimed at examining the clinical, histological and progressive features of the "erysipeloid" form of cutaneous leishmaniasis. Our patients were 3 females and one male more than 62 years old. Their cutaneous leishmaniasis was clinically characterised by an infiltrated and extensive plaque which was localised on the face covering the nose and cheeks looking like erysipelas. The treatment was intramuscular meglumine antimoniate (Glucantime) in three cases and metronidazole in one case. A regression without scar was noticed in all the cases. On the histological examination, we observed an intense epidermic and constant hyperplasia with presence of amastigotes in 3 cases. Our study shows the lesional polymorphism of the old word cutaneous leishmaniasis in our region. The "erysipeloid" form of cutaneous leishmaniasis is a rare clinical presentation which generally affects women. If the clinical aspect is very meaningful, the histological aspect is meaningful but not specific.

    The family of an "affected" subject with limb girdle dystrophy has been studied in order to assess the clinical-hereditary characteristics of the disease and to contribute to its definite genetic features (phenotypical expressiveness of the pathologic gene). The diagnosis of certitude was based on the anamnestic-clinical criteria and instrumental investigations, supported by histological and histochemical studies of the muscles. The clinical, electromyographic and biochemical data made it possible to distinguish the "affected" from the "subclinical" and the healthy subjects. The subjects that, without noticeable symptoms of neuromuscular disorders, showed a slight clinical expressiveness which didn't alter the normal social and working activities, have been defined "subclinical". The modalities of hereditary transmission of this form of muscular dystrophy are considered in the light of the genetics most present trends that are tending to overcome the dominant-recessive dualism. The possibility of a modality of transmission definable as "intermediate inheritance" is proposed. In the case of the examined family the hypothesis that a pathologic recessive autosomic gene gives rise to a clinical expressiveness in heterozygote subjects seems tenable. This situation definable as "incomplete recessive" is rarely found in the limb girdle dystrophy.

    Anti-N-methyl D-aspartate (NMDA) receptor encephalitis is the most common type of encephalitis in the spectrum of autoimmune encephalitis defined by antibodies targeting neuronal surface antigens. In the present study, the clinical spectrum of this disease is presented using instructive cases in correlation with the anti-NMDA receptor antibody titers in the cerebrospinal fluid (CSF) and serum. A total of 7 female patients admitted to the hospital of Hannover Medical School (Hannover, Germany) between 2008 and 2014 were diagnosed with anti-NMDA receptor encephalitis. Among these patients, 3 cases were selected to illustrate the range of similar and distinct clinical features across the spectrum of the disease and to compare anti-NMDA antibody levels throughout the disease course. All patients received immunosuppressive treatment with methylprednisolone, intravenous immunoglobulin and/or plasmapheresis, followed in the majority of patients by second-line therapy with rituximab and cyclophosphamide. The disease course correlated with NMDA receptor antibody titers, and to a greater extent with the ratio between antibody titer and protein concentration. A favorable clinical outcome with a modified Rankin Scale (mRS) score of ≤1 was achieved in 4 patients, 1 patient had an mRS score of 2 after 3 months of observation only, whereas 2 patients remained severely impaired (mRS score 4). Early and aggressive immunosuppressive treatment appears
