ABSTRACT
Esophageal varices commonly affect cirrhotic patients as a result of elevated portal system resistance. Blood pools within esophageal portosystemic collateral vessels, which can eventually rupture, leading to life-threatening hemorrhage. To prevent this, cirrhotic patients without a history of varices undergo endoscopic surveillance for varices every 2-3 years. We present an unusual case of variceal hemorrhage in a patient who was seen to have no varices on endoscopic evaluation only a month earlier.
ABSTRACT
Percutaneous endoscopic gastrostomy (PEG) and percutaneous endoscopic gastro-jejunal (PEG-J) tube placement are both common procedures regularly performed on patients requiring nutritional support. These procedures may be complicated by infection, hemorrhage, fistulization, or tube migration. We present an extremely rare case of a patient with a PEG-J tube that migrated into the esophagus.
ABSTRACT
PURPOSE: The purpose of this bibliometric study was to identify and analyze the most cited publications on acute distal biceps repair. METHODS: Using the Clarivate Analytics Web of Science database, we searched for the top 50 most cited publications on acute distal biceps repair and analyzed them based on various metrics. RESULTS: The top 50 publications were cited a total of 3171 times and approximately 151 times per year. However, although the literature on the topic is quite extensive, most publications only contain low-level evidence. In fact, 74% of the 50 most cited publications on the topic contain either level IV or V evidence. CONCLUSION: This study, through bibliometric analysis, demonstrates that the most often cited studies about acute distal biceps tendon repair are low level of evidence designs. This common injury and study design are ripe for larger randomized or prospective cohort studies.

Mungbean yellow mosaic virus disease (MYMVD) caused by single-stranded DNA begomovirus is the most prominent threat to the mungbean crop in Pakistan. Mungbean genotypes consisting of 127 varieties/lines were screened for MYMVD under natural field conditions. No genotypes were found to be immune or highly resistant against MYMVD. Genotypes showing resistant and tolerant responses in field screening trials were screened using sequence characterized amplified region (SCAR) markers linked with the MYMVD-resistance gene. SCAR markers amplified the desired band only in the resistant and tolerant genotypes, while no amplification was observed in susceptible genotypes. SCAR markers will be useful for future breeding and varietal developmental programs and mungbean genotypes can be screened on the molecular level.

Urdbean (Vigna mungo) is an important pulse crop grown worldwide. Urdbean leaf crinkle virus (ULCV) is a pathogen of urdbean found in Pakistan that causes huge losses in yield. Forty urdbean varieties/lines were screened against the virus under field conditions during spring season 2009. None of the lines appeared to be highly resistant or resistant. On the basis of a 0-5 disease rating scale and disease severity index, genotypes varied significantly in their reaction to ULCV. Four lines (M-6206, IAM-382-15, IAM-133, and Mash-1) were moderately resistant, eight were rated as moderately susceptible, and 21 as susceptible; the remaining seven lines were highly susceptible. RAPD analyses revealed an extensive amount of variation, which could be used for cultivar identification. Genetic differentiation among urdbean genotypes was similar to the field screening data. The varieties 6065-3 and 6206 were highly susceptible and moderately resistant, respectively, to ULCV under field conditions, confirmed by the RAPD analysis. These varieties were the most diverse varieties in the similarity matrix (67.2%), while the varieties IAM-382-9 and 07M003 were the most similar (98.4%). This information will help in the recognition of available resistant germplasms that can resist this disease and will be utilized for urdbean improvement in Pakistan.
