Onychogryphosis is a disorder of nail plate growth that is clinically characterized by an opaque, yellow-brown thickening of the nail plate with associated gross hyperkeratosis, elongation, and increased curvature. It is most common in older adults and patients with poor personal care. It is a relatively common and important condition because patients may suffer from pain, secondary complications, and cosmetic concerns. We present the case of a 67-year-old man with a 30-year history of severe th

Chronic intestinal pseudo-obstruction (CIPO) is an extremely rare condition with symptoms of recurrent intestinal obstruction without any lesions. The outcomes of pediatric CIPO and predictors for the outcomes have not yet been well established. We analyzed the clinical outcomes and associated factors for the outcomes of pediatric CIPO. We retrospectively reviewed 66 primary CIPO patients diagnosed between January 1985 and December 2017. We evaluated parenteral nutrition (PN) factors such as PN

Despite the small numbers, the outcomes of EVAR for treatment of r-AAA were very promising, even in selected cases with unfavorable anatomy. These outcomes were achieved by a dedicated and well-trained team approach, and by use of high-end angiographic technology. Finally, ACS after EVAR is not uncommon, and requires a high index of suspicion as well as liberal use of decompressive surgery.

Beau lines, onychomadesis, and retronychia are nail conditions with their own characteristic clinical findings. It has been hypothesized that these 3 disorders may share a common pathophysiologic mechanism of slowing and/or halting nail plate production at the nail matrix. We report the case of a 41-year-old woman who presented with concurrent Beau lines, onychomadesis, and retronychia 6 months following a diagnosis of scurvy. Simultaneous presentation of these 3 nail conditions is not commonly

PURPOSE: We aimed to investigate the extent of heterogeneity in medical terminology between South and North Korea by comparing medical terms related to the colorectal system. METHODS: North Korean medical terms were collected from the sections on diseases of the small intestine and colon in a surgery textbook from North Korea, and those terms were compared with their corresponding terms in a South Korean medical terminology textbook. The terms were categorized as either identical, similar, showi

Bacillus Calmette-Guerin (BCG) vaccination can cause lymphadenitis. The purpose of the current study was to describe patient characteristics and clinical courses of lymphadenitis associated with BCG vaccination. A total of 171 patients who visited a tertiary hospital with a diagnosis of BCG-associated lymphadenitis between January 2012 and June 2017 were included. The diagnostic criteria were a history of BCG vaccination on the symptomatic side, absence of tenderness and raised temperature over

The aim of this study was to determine whether there is a difference in the degree of apoptosis and the pathways leading to necrotizing enterocolitis (NEC) between preterm and full-term rat pups. To achieve this goal, we investigated the pathogenesis of NEC. premature Sprague‒Dawley (SD) rat pups delivered by cesarean section at a gestational age of 21 days (preterm group), as well as full-term SD rat pups four days after birth (full-term group). The pups were exposed to lipopolysaccharides (LPS

Purpose: Patients with esophageal atresia (EA) often have feeding problems due to esophageal dysmotility, gastroesophageal reflux, and dysphagia, which can delay growth in children. The purpose of this study was to investigate whether proper growth is achieved during the early childhood of patients with EA and to predict associated factors. Methods: Clinical data of patients with EA who underwent corrective surgery between 2014 and 2017 were collected retrospectively. We analyzed a total of 17 p
