Background.Current detection methods for Clostridium difficile infection (CDI) can be time-consuming and have variable sensitivities. Real-time polymerase chain reaction (PCR) may allow earlier and more accurate diagnosis of CDI than other currently available diagnostic tests. A meta-analysis was performed to determine the diagnostic accuracy of real-time PCR.Methods.We searched MEDLINE (Pubmed/Ovid) and 4 other online electronic databases (1995-2010) to identify diagnostic accuracy studies that compared PCR with cell culture cytotoxicity neutralization assay (CCCNA) or anaerobic toxigenic culture (TC) of C. difficile. Screening for inclusion, data extraction, and quality assessment were carried out independently by 2 investigators and disagreements resolved. Data were combined by means of a random-effects model, and summary receiver operating characteristic curves and diagnostic odds ratios were calculated.Results.Nineteen studies (7392 samples) met our inclusion criteria. The overall mean sensitivity of PCR was 90% (95% confidence interval [CI]: 88%-91%), specificity 96% (CI: 96%-97%), positive likelihood ratio 26.89 (CI: 20.81-34.74), negative likelihood ratio 0.11 (CI:. 08-.15), diagnostic odds ratio 278.23 (CI: 213.56-362.50), and area under the curve 0.98 (CI:. 98-.99). Test accuracy depended on the prevalence of C. difficile but not on the reference test used. At C. difficile prevalence of <10%, 10%-20% and >20% the positive predictive value and the negative predictive value were 71%, 79%, 93% and 99%, 98% and 96%, respectively.Conclusions.Real-time PCR has a high sensitivity and specificity to confirm CDI. Overall diagnostic accuracy is variable and depends on CDI prevalence. © 2011 The Author.

Purpose: MicroRNAs (miRNA) have potential prognostic value for colorectal cancers; however, their value based on patient race/ethnicity and pathologic stage has not been determined. The goal was to ascertain the prognostic value of 5 miRNAs with increased expression in colorectal cancers of African American (black) and non-Hispanic Caucasian (white) patients. Experimental Design: TaqMan quantitative real-time PCR was used to quantify expression of miR-20a, miR-21, miR-106a, miR-181b, and miR-203 in paired normal and tumor colorectal cancer archival tissues collected from 106 black and 239 white patients. The results were correlated with overall survival based on patient race/ethnicity and pathologic stage. Because decisions about adjuvant therapy are important for stage III colorectal cancers, and because miR-181b seemed to have prognostic value only for stage III black patients, we assessed its prognostic value in a separate cohort of 36 stage III colorectal cancers of blacks. Results: All 5 miRNAs had higher expression in colorectal cancers (>1.0-fold) than in corresponding normal tissues. High expression of miR-203 was associated with poor survival of whites with stage IV colorectal cancers (HR = 3.00; 95% CI, 1.29-7.53), but in blacks it was an indicator of poor survival of patients with stages I and II colorectal cancers (HR = 5.63; 95% CI, 1.03-30.64). Increased miR-21 expression correlated with poor prognosis for white stage IV patients (HR = 2.50; 95% CI, 1.07-5.83). In both test and validation cohorts, high miR-181b expression correlated with poor survival of only black patients with stage III colorectal cancers (HR = 1.94; 95% CI, 1.03-3.67). Conclusion: These preliminary findings suggest that the prognostic value of miRNAs in colorectal cancers varies with patient race/ethnicity and stage of disease. © 2013 American Association for Cancer Research.

Pure neuritic leprosy has always been an enigma due to its clinical and management ambiguities. Although only the Indian Association of Leprologist's classification recognizes 'pure neuritic leprosy' as a distinct sub group of leprosy, cases nonetheless are reported from various countries of Asia, Africa, South America and Europe, indicating its global relevance. It is important to maintain pure neuritic leprosy as a subgroup as it constitutes a good percentage of leprosy cases reported from India, which contributes to more than half of global leprosy numbers. Unfortunately, a high proportion of these patients present with Grade 2 disability at the time of initial reporting itself due to the early nerve involvement. Although skin lesions are absent by definition, when skin biopsies were performed from the skin along the distribution of the affected nerve, a proportion of patients demonstrated leprosy pathology, revealing sub-clinical skin involvement. In addition on follow-up, skin lesions are noted to develop in up to 20% of pure neuritic leprosy cases, indicating its progression to manifest cutaneous disease. Over the decades, the confirmation of diagnosis of pure neuritic leprosy has been subjective, however, with the arrival and use of high-resolution ultrasonography (HRUS) for nerve imaging, we have a tool not only to objectively measure and record the nerve thickening but also to assess the morphological alterations in the nerve including echo texture, fascicular pattern and vascularity. Management of pure neuritic leprosy requires multidrug therapy along with appropriate dose of systemic corticosteroids, for both acute and silent neuritis. Measures for pain relief, self-care of limbs and physiotherapy are important to prevent as well as manage disabilities in this group of patients. © 2016 Indian Journal of Dermatology, Venereology, and Leprology.

Newer management options are needed for leprosy control even at present, as it is predicted that new cases of leprosy will continue to appear for many more years in future. This article detail newer methods of clinical grading of peripheral nerve involvement (thickening, tenderness and nerve pain which are subjective in nature) and the advances made in the use of Ultrasonography and Colour Doppler as an objective imaging tool for nerves in leprosy. It also briefly discusses the newer drugs and alternative regimens as therapeutic management options which hold promise for leprosy in future.

Congenital Anomalies | Year: 2013

Anomalies of the umbilical venous system are perplexing essentially due to dissection errors and vascular connection delineation failure. Continuation of umbilical vein into the extra-hepatic portal vein is classified as group IV umbilical vein anomaly and involves the vitelline vein or its remnants. Despite this categorization most examiners ascribe fetal extra hepatic abdominal vascular abnormality as an umbilical vein anomaly. Since these anomalies involve vitelline vein, the term "umbilical vein anomaly" is inappropriate and should be referred to as "vitelline vein abnormalities". Vitelline vein abnormalities are exceedingly rare and to the best of our knowledge only three cases have been reported prenatally. We report three cases presenting with intrauterine fetal demise and on perinatal autopsy demonstrating aneurysmally dilated group IV umbilical vein anomaly. Review of the literature, embryological basis and clinical implications of persistent vitelline vein and its varix are discussed. © 2013 Japanese Teratology Society.

Background & Aims: In the past decade, there has been a growing epidemic of Clostridium difficile infection (CDI). During this time, use of proton pump inhibitors (PPIs) has increased exponentially. We evaluated the association between PPI therapy and the risk of CDI by performing a meta-analysis. Methods: We searched MEDLINE and 4 other databases for subject headings and text words related to CDI and PPI in articles published from 1990 to 2010. All observational studies that investigated the risk of CDI associated with PPI therapy and used CDI as an end point were considered eligible. Two investigators screened articles independently for inclusion criteria, data extraction, and quality assessment; disagreements were resolved based on consensus with a third investigator. Data were combined by means of a random-effects model and odds ratios were calculated. Subgroup and sensitivity analyses were performed based on study design and antibiotic use. Results: Thirty studies (25 case-control and 5 cohort) reported in 29 articles met the inclusion criteria (n = 202,965). PPI therapy increased the risk for CDI (odds ratio, 2.15, 95% confidence interval, 1.81-2.55), but there was significant heterogeneity in results among studies (P < .00001). This association remained after subgroup and sensitivity analyses, although significant heterogeneity persisted among studies. Conclusions: PPI therapy is associated with a 2-fold increase in risk for CDI. Because of the observational nature of the analyzed studies, we were not able to study the causes of this association. Further studies are needed to determine the mechanisms by which PPI therapy might increase risk for CDI. © 2012 AGA Institute.

Meckel-Gruber syndrome is a rare autosomal recessive lethal malformation characterised by typical manifestations of occipital encephalocele, bilateral polycystic kidneys and post axial polydactyly. But clinically unsuspected or atypical features may be discovered at autopsy or pathological study. One such rare case, diagnosed by ultrasound scan at 21weeks of gestation was terminated and presented here for discussion, with its phenotypic manifestations detailed by autopsy and histo-pathological examination.

This study was undertaken to evaluate the variations in thyroid profile, lipid profile and transaminase levels in overt hypothyroid patients, compared to healthy controls. Thirty hypothyroid patients, both male & female, in the age group of 20 to 50 years (study group) and 30 age & sex matched healthy subjects (control group) were enrolled in the study. We found significant increase in mean levels of total cholesterol, serum triglycerides, LDL-c, AST & TSH and significant decrease in T3 & T4 in study group compared to controls. There was no significant difference in HDL -c values between two groups. The ALT and VLDL-c values were near the upper limits of normal range in study group, while they were near the lower limit in control group, the difference being significant.

Gastrointestinal Stromal Tumours are the commonest mesenchymal tumors of the gastrointestinal tract, the stomach and small intestine being the favored sites. They rarely occur in the colon and rectum and esophagus. The diagnosis is difficult, especially when there are no pathognomic features to suggest GIST on preoperative clinical examination and investigations, and only a detailed histopathological analysis of the specimen reveals their true nature. Here, we report a case of a young female patient who presented with vague abdominal pain which was diagnosed histopathologically as GIST of the stomach.

Objective: To study the effects of N-acetylcysteine (NAC) and atorvastatin on endothelial dysfunction in patients with systemic lupus erythematosus (SLE). Materials and Methods: Thirty-two SLE patients and age, sex-matched 10 healthy control subjects were studied. The patients were between 17 and 65 years of age and positive for diagnostic tests, such as antinuclear antibodies (ANA). Photoplethysmogram (PPG) detects the changes in the amount of light absorbed by hemoglobin, which reflects changes in the blood volume. Pulse wave analysis was performed at rest, 30 s, 90 s after shear stress, and 10 min after 300 μm of salbutamol inhalation. Results: Stiffness index (SI) of patients before the treatment was 8.46±2.78 cm/s and of controls was 6.07±1.4 cm/s (P = 0.002) and that of reflection index (RI) was 73±13 for patients and 65±7 for controls (P = 0.001). The percentage change in RI after salbutamol inhalation for controls and patients were -16±6 and -7±4 (P = 0.001), respectively, indicating the presence of endothelial dysfunction. The percentage decrease in RI after salbutamol inhalation was from -2.36±0.76 to 7.92±1.46 in patients treated with N-acetylcysteine (NAC, P = 0.007). The percentage decrease in RI after salbutamol inhalation was from 6.36±1.21 to -9.92±1.21 in patients treated with atorvastatin (P = 0.05). This indicated the improvement in endothelial function. There was decrease in C-reactive protein (CRP) from 1.03±0.72 mg/dL to 0.52±0.22 mg/dL and that of malondialdehyde (MDA) from 11.20±4.07 nmol/mL to 8.81±2.79 nmol/mL with N-acetylcysteine treatment (P < 0.05). The CRP was decreased from 1.11±0.92 mg/dL to 0.440.16 mg/dL (P = 0.05) and that of MDA was decreased from 9.37±3.29 nmol/mL to 8.51±3.27 nmol/mL after treatment with atorvastatin. It showed improvement in oxidative stress with these treatments. Conclusion: The presence of arterial stiffness indicated endothelial dysfunction. There was reduction in RI and SI with treatment of N-acetylcysteine and atorvastatin suggesting improvement in endothelial dysfunction. There was decrease in CRP (a marker of inflammation) and MDA after treatment with N-acetylcysteine suggesting improvement in endothelial dysfunction. There was reduction in CRP after treatment with atorvastatin, suggesting improvement in endothelial function. Improvement in endothelial dysfunction is associated with decreased incidence of cardiovascular and cerebrovascular accidents.
