Osteoporosis (OP) is one of the most common chronic disorders; the disabilities that result from osteoporotic fractures (OPF) worldwide have an enormous impact on the health of individuals, societies and economies. Genetic factors together with environmental factors play an important role in regulating the development of osteoporosis as well as contributing to the susceptibility of osteoporotic...

Evaluating predictive factors for high-risk adenomas at the third colonoscopy based on two prior colonoscopies may help evaluate high-risk adenoma at the third colonoscopy. We analyzed clinical data of 131 patients at Severance Hospital from January 1997 to January 2011. All of them underwent two subsequent colonoscopies after removal of adenomas during an initial colonoscopy. Among 20 patients...

PURPOSE The adenoma detection rate is commonly used as a measure of the quality of colonoscopy. This study assessed both the association between the adenoma detection rate and the quality of bowel preparation and the risk factors associated with the adenoma detection rate in screening colonoscopy. METHODS This retrospective analysis involved 1,079 individuals who underwent screening colonosco...

Pleomorphic adenoma is mixed and usually benign tumor originating salivary glands. The most common salivary gland tumor is pleomorphic adenoma. The most common localization of pleomorphic adenoma is parotid gland. Although it is found in major salivary gland, pleomorphic adenoma may be found paranasal sinuses and nasal cavity rarely. A 74-year-old female presented with a 3-month history of ri...

BACKGROUND Laterally spreading tumors (LSTs) are generally defined as lesions >10 mm in diameter, are characterized by lateral expansion along the luminal wall with a low vertical axis. In contrast to other forms of tumor, LSTs are generally considered to have a superficial growth pattern and the potential for malignancy. We focused on this morphological character of LSTs, and analyzed the gene...

BACKGROUND Intracranial vascular complications following radiosurgery are extremely rare. CASE DESCRIPTION We report a case of stenosis in the internal carotid artery 5 years after gamma knife radiosurgery for a recurrent pituitary adenoma. Percutaneous transluminal angioplasty was performed successfully with anatomical and functional improvement. CONCLUSION These results suggested the impo...

OBJECTIVE The objective of this study was to assess the association between colorectal neoplasia and sporadic duodenal adenoma. METHODS A retrospective case control study was conducted using the databases of two major teaching hospitals in Western Australia. The frequency of colorectal neoplasia in patients with sporadic duodenal adenomas was compared with that in a control group of patients ...

BACKGROUND Research on the association between fruit and vegetable intake and risk of colorectal adenoma is inconclusive. OBJECTIVE We studied whether intake of fruit, vegetables, or their subgroups is associated with a lower risk of prevalent colorectal adenoma. DESIGN In men and women (aged 55-74 y) who were screened for colorectal cancer in the Prostate, Lung, Colorectal, and Ovarian Can...

PURPOSE To analyze postoperative outcomes of prostate surgery, resected specimen weight is commonly used. The difference between the preoperative calculated transitional zone volume and actual enucleated specimen weight following holmium laser enucleation of the prostate (HoLEP) is reported at over 20%. The reason for this difference is unclear. We assessed the association of volume of the pros...
