Background Rectal biopsy and its histopathological study with hematoxylin and eosin (HE) is the gold standard for Hirschsprung's disease (HD) diagnosis. However, there are some limitations in the diagnosis of ganglion cells in HE approach. Recently, it was reported that the utility of Calretinin is a reliable ancillary immunohistochemistry (IHC) test for HD diagn...

background: intensified strategy includes special attention to the symptoms such as cough (more than two weeks), fever (more than three weeks), night sweats (more than three weeks), and weight loss (more than 3 kg per month). if any of the above symptoms was positive, in suspected individuals for tb, more assessment should be done. the aim of this study was to compare between intensified and ro...

Methodology This is a prospective observational study in 51 patients with T1-T2 N0 OCSCC. Pre-operative ultrasonography (US) of the neck was performed in all patients. USgFNAC was performed in patients where US was reported as indeterminate or positive. SNB was performed in all patients and was followed by elective neck dissection (END). The sensitivity, specificity, positive predictive value (...

OBJECTIVES To characterize the cytopathologic outcome of lesions detected on positron emission tomography (PET) scan. STUDY DESIGN Cases with fine needle aspiration (FNA) performed because of a PET-positive lesion over an 18-month period were reviewed. Correlation with the standard uptake value (SUV) (using 2.5 as a cutoff value) was carried out. RESULTS A total of 112 FNAs were found, of w...

Clusters of nosocomial infection often occur undetected, at substantial cost to the medical system and individual patients. We evaluated binary cumulative sum (CUSUM) and moving average (MA) control charts for automated detection of nosocomial clusters. We selected two outbreaks with genotyped strains and used resistance as inputs to the control charts. We identified design parameters for the C...

The type-specific persistence of oncogenic human papillomavirus (HPV) is considered to be the true precursor of cervical cancer at which the transcription of the viral oncogenes E6 and E7 is necessary for the malignant transformation and maintenance of the neoplastic state. In the present pilot study, a cohort of 66 women was investigated from a routine office-based screening population who had...

INTRODUCTION Due to limitation of colonoscopy in assessing the entire bowel and patients' intolerance in inflammatory bowel disease (IBD), in the current study, we aimed to prospectively compare the accuracy of 99mTc(V)-dimercaptosuccinic acid (DMSA) and fecal calprotectin with ileocolonoscopy as new methods for localizing inflammations. METHODS Current prospective study conducted between 2012 ...

Several trigger systems have been developed to screen medical records of hospitalized patients for adverse events (AEs). Because it's too labor-intensive to screen the records of all patients, usually a sample is screened. Our sample consists of patients who died during their stay because chances of finding preventable AEs in this subset are highest. Records were reviewed for fifteen triggers (...

BACKGROUND Epidermal growth factor receptor (EGFR) is a novel target for therapy in a subset of non-small cell lung cancer (NSCLC). Tumors with EGFR mutations showed good response to EGFR tyrosine kinase inhibitors (TKIs). We aimed to identify the discriminating capacity of immunohistochemistry (IHC) to detect EGFR L858R and del E746-A750 mutations in NSCLC patients and predict EGFR TKIs respon...

PURPOSE To assess the specific value of subtraction ictal and inter-ictal SPECT co-registered to MRI (SISCOM) in identifying the epileptogenic zone (EZ) and predicting postoperative outcomes in epileptic surgical patients. METHOD A meta-analysis of studies published from January 1995 to June 2015 was conducted through a comprehensive literature search, and 11 studies were included. R software...
