ABSTRACT

Ischemic colitis is a frequent disorder of large bowel in elderly persons or in debilitated patients with a variable underlying medical problems. Ischemic colitis may result from alterations in the systemic circulation or anatomic or functional changes in the local mesenteric vasculature. In most cases, no specific cause for the ischemic colitis is identified. Cases of ischemic colitis after enema for bowel cleansing have been rarely reported, but there has been no case report after normal saline enema. We report a case of ischemic colitis in a 72-year old patient with well-controlled hypertension, presenting as bloody diarrhea which developed after normal saline enema for preoperative bowel cleansing.

ABSTRACT

A duodenal diverticulum is common and usually originates in the second portion of the duodenum. The majority of diverticula are asymptomatic; however, they may sometimes present with symptoms such as obstruction, hemorrhage, perforation, jaundice and pancreatitis. Active bleeding from a duodenal diverticulum is rare, and moreover, Dieulafoy's lesion as a cause is quite rare with very few cases reported so far. The use of endoscopic methods instead of surgery in achieving hemostasis has been on the increase with the widespread use and improvement in endoscope instrumentation and accessories. Of these methods, the use of endoscopic hemoclipping for Dieulafoy's lesion is considered more effective and safe than the use of other methods, such as injection and thermal methods. We report here a case of a bleeding Dieulafoy's lesion in a duodenal diverticulum treated by endoscopic hemoclipping.

ABSTRACT

Ectopic gastric mucosa is known to occur throughout the gastrointestinal tract. Ectopic gastric mucosa in the duodenum is classified into the developmental (heterotopic gastric mucosa) and acquired types (gastric metaplasia). Gastric metaplasia may be present in up to 64% of normal individuals but heterotopic gastric mucosa is quite rare. A heterotopic gastric mucosa in the duodenum may be asymptomatic but can give rise to perforation, hemorrhage, and intestinal obstruction in rare cases. Therefore, periodic endoscopic surveillance is recommended in these cases. Endoscopically, the appearance of a heterotopic gastric mucosa shows a mainly elevated lesion with multiple nodularity. We report a case of 1.5 x 1.2 cm sized polypoid lesion of the duodenum in an asymptomatic 31 year-old man. The mass was resected endoscopically and diagnosed as a heterotopic gastric mucosa.

ABSTRACT

The gastric carcinoma displays various macroscopic appearances ranging from well defined protuberant to diffuse infiltrating tumors but its histological diagnosis is usually simple when performing an endoscopic biopsy. A few gastric cancinomas resemble submucosal tumors (SMT). A gastric carcinoma with a SMT-like appearance is extremely rare, and reportedly accounts for 0.1% to 0.63% of all resected gastric carcinomas in Japan. A histological diagnosis of a SMT-like gastric carcinoma by repeated endoscopic biopsies is often difficult as the tumors are almost entirely covered with normal mucosa. When one sees the lesions in an upper gastrointestinal endoscopy, one should be careful about the location of depression, redness and coating that deviates from the top of the tumor. Here we report two cases of SMT-like gastric carcinomas, diagnosed by the usual endoscopic biopsy method and treated with surgery, with an accompanying review of the recent literature.

ABSTRACT

Medullary thyroid carcinoma (MTC) is a relatively rare malignant thyroid disease that accounts for approximately 1% to 5% of all thyroid carcinomas. MTC occurs as a sporadic disease and as an inherited disease with the multiple endocrine neoplasia type 2A (MEN2A), MEN2B, and familial non-MEN medullary carcinoma (FMTC). MEN2A is characterized by MTC, pheochromocytoma, and parathyroid adenoma. The mutation of RET proto-oncogene plays an important role in MEN2A syndromes. Recently the authors diagnosed MEN2A patient and screened his family with thyroid ultrasonogram and RET proto-oncogene analysis. A genetic analysis of the peripheral leukocyte showed a codon 618 mutation (Cys618Arg) at exon 10 of the RET proto-oncogene in a family presenting third generations from age 7 to age 56 years. We report this case of MEN2A with a review of the related literatures.

ABSTRACT

BACKGROUND: Nontuberculous mycobacterial (NTM) infections are increasingly being recognized as a cause of chronic pulmonary disease. This study describes the prevalence of NTM species from clinical specimens and the clinical characteristics of NTM pulmonary disease. MATERIAL AND METHODS: The NTM isolated from March 2003 to December 2003 at the Kosin Medical Center were identified using an oligonucleotide chip containing the internal transcribed space (ITS) sequence. The medical records of the patients with the NTM isolates, who fulfilled the 1997 ATS diagnostic criteria for NTM pulmonary disease, were analyzed, retrospectively. RESULTS: Twenty four species (24.2%) of NTM were isolated from 99 cultured AFB specimens. M. avium complex (MAC) (13 isolates), M. szulgai (3), M. kansasii (2), M. malmoense (2), M. abscessus (1), M. chelonae (1), M. scrofulaceum (1), and unclassified (1). Of the 23 patients with isolated NTM, 11 patients were found to be compatible with a NTM pulmonary infection according to the ATS criteria; MAC was found in 6 cases (54.5%), M. szulgai in 2 cases (18.2%), and M. abscessus, M. szulgai, M. kansasii and M. malmoense in 1 case each (9.1%). Ten patients (91%) were male and the median age at diagnosis was 61 years. In the pre-existing diseases, malignant disease was found in 6 cases including 5 patients with lung cancer, and history of old pulmonary tuberculosis was identified in 4 cases. The radiological patterns showed lung destruction lung in 3 cases, a cavitary mass in 3 cases, a nodular pattern in 2 cases, and reticulonodular, consolidation and a bronchiectasis pattern were in 1 case each. CONCLUSION: Various types of NTM pulmonary diseases were`found in a tertiary hospital at Busan, Korea. The NTM pulmonary diseases were caused by MAC, M. szugai, M. kansasii, M. malmoense, M. abscessus, M. chelonae, and M. scrofulaceum in the order of frequency.
