Physical activity can reduce the prevalence of gallstone disease among males: An observational study.

Several previous studies have reported that physical activity (PA) levels can independently affect the prevalence of gallstone disease (GD) in Western countries. However, this association has not been reported in Eastern countries. Therefore, this study aimed to determine whether PA is an independent determinant of GD prevalence in a Korean population, according to the World Health Organizations Global Recommendations on PA for Health.

The grade of nonalcoholic fatty liver disease is an independent risk factor for gallstone disease: An observational Study.

There have been reports linking nonalcoholic fatty liver disease (NAFLD) with gallstone disease (GD) owing to shared risk factors. However, there are no reported associations between the different NAFLD grades and GD. This study aimed to determine whether NAFLD grade is an independent risk factor for GD in a Korean population.

The Prevalence of Gallstone Disease Is Significantly Lower in Natives than in Migrants of Jeju Island.

Background: The eating habits of Jeju Island natives are quite different from those of the mainland people because of geographic isolation. Diet is a main factor affecting gallstone disease. We investigated the prevalence of gallstone disease in both Jeju Island natives and migrants and studied the risk factors affecting gallstone disease in the Jeju Island people.

Partial purification and properties of a cysteine protease from citrus red mite Panonychus citri.

Several studies have reported that the citrus red mites Panonychus citri were an important allergen of citrus-cultivating farmers in Jeju Island. The aim of the present study was to purify and assess properties of a cysteine protease from the mites acting as a potentially pathogenic factor to citrus-cultivating farmers. A cysteine protease was purified using column chromatography of Mono Q anion exchanger and Superdex 200 HR gel filtration.

A completely isolated intestinal duplication cyst mimicking ovarian cyst torsion in an adult.

Intestinal duplications are rare congenital anomalies that can occur anywhere in the gastrointestinal tract. They are most commonly located in the ileum and are usually detected in infancy or early childhood. Duplicated segments are usually firmly attached to and sometimes communicate with the normal gastrointestinal tract.

Management of postoperative hemorrhage after pancreatoduodenectomy.

Background/aims: Hemorrhage after pancreatoduodenectomy is a severe, life-threatening complication. This study was conducted to determine the guidelines appropriate for the prevention and management of hemorrhagic complications.

Methodology: We reviewed the medical records of 456 patients who had undergone pancreatoduodenectomy at our hospital between 1991 and 2000.
