A umbilical omphalomesenteric duct polyp is the result of incomplete closure of the omphalomesenteric duct, which connects the midgut with the yolk sac of the embryo. It may be associated with underlying embryologic anomalies such as Meckels diverticulum and umbilical enteric fistula, the complications of which may at times be fatal. This rare malformation should be clinically discerned from persistent granulation tissue or pyogenic granuloma. Histologically, it shows a polypoid lesion consisting of ectopic gastrointestinal epithelium with the appearance of gastric, intestinal, or colonic mucosa. We report a case of an umbilical omphalomesenteric duct polyp in an 8-year-old male patient, who had had a bright-red polyp on the umbilicus from the age of 1 month and had not had any other types of underlying abnormalities.

Obesity is a chronic relapsing disease associated with cardiovascular disease and cancer with a growing incidence. Since obesity is a complex disease that is affected by a variety of factors, including social, cultural, and environmental factors, it should be approached by establishing an integrated and comprehensive treatment strategy. It is difficult to achieve a sufficient amount of weight loss in most obese patients through lifestyle interventions alone, so pharmacotherapy in primary care should be actively considered as an additional treatment. Currently, there are four drugs that can be used for long-term weight management in Korea: orlistat, naltrexone/bupropion, phentermine/topiramate, and liraglutide. Sympathomimetics, such as phentermine, diethylpropion, phendimetrazine, and mazindol, can only be used for short-term treatment. These drugs can induce weight loss by suppressing appetite or inhibiting fat absorption in the gut. The prescription of such drug treatments should be based on evidence-based clinical care and tailored to the patient. Patient-tailored obesity drug treatments should be performed taking into consideration the advantages, side effects, and safety issues of each drug. Considering that obesity is a chronic disease that must be controlled for a lifetime, obese patients should be guided by clinicians to maintain their weight sustainably by setting common and realistic goals.

We present a case of Korean pediatric patient with pre-B cell type acute lymphoblastic leukemia (ALL) with trisomy 5 as a sole cytogenetic anomaly. Here, we compare and describe the present case with previous pediatric case reports and provide a review of the literature. This case report may help elucidate the poor prognostic impact of trisomy 5 as a sole cytogenetic anomaly in pediatric patients with ALL. Additional studies are needed to confirm this hypothesis.

A 51-year-old Korean woman presented with a non-tender, well-demarcated, reddish, edematous patch on the right anterior chest where a previous mastectomy and radiation therapy had been performed. She had been diagnosed as having infiltrating ductal carcinoma of the right breast about 1 year ago. Histopathological findings of the skin lesions were consistent with inflammatory metastatic carcinoma of the breast. Inflammatory carcinoma or carcinoma erysipeloides is a well-established entity most frequently associated with carcinoma of the breast. It is characterized by dermal lymphatic invasion by malignancy and clinically should be distinguished from erysipelas or cellulitis. We describe a case of inflammatory metastatic carcinoma derived from an infiltrating ductal carcinoma of the breast which can be clinically confused with radiation dermatitis.

PURPOSE: Because there are no significant differences of the clinical findings between the appendicitis and cecal diverticulitis, it is very difficult to make a correct diagnosis preoperatively and to choose a appropriate management intraoperatively. The purpose of this study is to investigate the clinical charateristics of right diveticulitis and to evaluate the appropriateness of surgical management. METHODS: We reviewed 45 cases of right colonic diverticulitis which underwent emergency operation under the impression of acute appendicitis during 10 years from January 1988 to December 1997. RESULTS: Of them, 38 cases were treated by diverticulectomy with appendectomy (Group I), and 7 cases were treated by resection (ileocecal resection or right hemicolectomy) (Group II). The male to female ratio was 4:1, and the mean age was 38.2 years. In Group I, all cases had a solitary inflamed cecal diverticulum. In group II, two cases had a solitary cecal diverticulitis, whereas five cases had multiple ones. Postoperative complications were found in 14 cases, but all of them were not significant. Postoperative Barium enema was performed in 22 cases of Group I, in two cases of Group II. In Group I, 8 cases had a residual diverticulum at postoperative Barium enema. In Group II, no residual diverticulum was shown. Follow-up study by Telephone was done at 16 cases, there were no symptomatic recurrences. CONCLUSIONS: In conclusion, when right colonic diverticulitis is found at the time of operation, surgical management is a safe treatment with low morbidity and low recurrence rate. Diverticulectomy with appendectomy is a safe surgical procedure for the uncomplicated diverticulitis. If diverticulitis is complicating, multiple or undistinguishable with malignancy, resection (ileocecal resection, right hemicolectomy) should be considered as a primary surgical treatment. Postoperative colon study is helpful, due to high incidence of residual diverticulum.

PURPOSE: Brainstem auditory evoked response(BAER) is used as screening test for hearing disorders, damages of the central nervous system and congenital anomalies. We studied the difference values according to gender and stimulation sites in normal full-term infants. METHODS: We performed BAER in 38 male and 28 female normal full-term infants, delivered in the Gil Medical Center, Gachen Medical School, from March to July 1996, aged one to seven days. Amplitude I, V, V/I and latency I, III, V and interpeak latency(IPL) I-III, III-V, I-V were measured at 90, 60, 45, 30 dB. Data were analyzed between both sex and between both ears with Student t-test. RESULTS: There were no significant difference in male and female group with the same side's stimulation. At 90 dB, amplitude I of left ear stimulation was significantly higher than right in male and female. Amplitude V/I of right ear stimulation was significantly higher than left ear stimulation in total only. At 90 dB, latency I of right was significantly longer than left in male and female. Latency III of right was longer significantly in total only. IPL I-III, I-V was significantly longer in left than right in male and total. At 60 dB intensity, all data except latency I in total, showed no significant difference. CONCLUSIONS: Interpreting BAER, stimulation site and intensity should be considered. and further studies will be needed for the evaluation of the difference between left and right ear.

Cis-diamminedichloroplatinum II (cisplatin) has been reported to induce cell death. However, the mechanism by which cisplatin is induced the apoptosis of cancer cells is still unclear. To evaluate the mechanistic insights of apoptosis by cisplatin, we tested the activities of apoptotic signaling pathway in HeLa cells. Apoptotic death of HeLa cells by cisplatin was confirmed by ladder-pattern fragmentation of genomic DNA. Cisplatin induced the activation of caspase-3 and 9 proteases in a time dependent manner. The caspase-3 protease activation and the cleavage of poly (ADP-ribose) polymerase (PARP) and procaspase-3 was demonstrated. We also showed that the expression of Bcl-2 and Bcl-xL was markedly decreased by the addition of cisplatin in HeLa cells. Moreover, expression of Fas and FasL proteins was increased by cisplatin. These data suggest that cisplatin triggers the activation of apoptotic signaling pathway in human cervical cancer, HeLa cells, via affects the expression of Fas, FasL and Bcl-2 families as well as triggers the activation of caspase-3 and -9 proteases.

Attempts were made to isolate and identify Korean bovine Babesia parasite. Blood samples were collected from Holstein cows in Korea, and Babesia parasites were propagated in SCID mice with circulating bovine red blood cells for isolation. The isolate was then antigenically and genotypically compared with several Japanese isolates. The Korean parasite was found to be nearly identical to the Oshima strain isolated from Japanese cattle, which was recently designated as Babesia ovata oshimensis n. var. Haemaphysalis longicornis was the most probable tick species that transmited the parasite.
