Prader-Willi(PW)syndrome is characterized by obesity, hypotonia, mental retardation, hypogonadism, short stature, excessive eating and characteristic facial appearance. Diabetes mellitus has been considered a component of PW syndrome. Recently this syndrome is caused by the absence of paternally derived genes normally located on chromosome segment 15 q11-q13 or may be the result of maternal uniparental disomy with the absence of paternally derived 15 q11-q13 region. The developement of probes containing segments of DNA from chromosome region 15 q11-q13 provides the oppotunity to confirm the diagnosis of PW syndrome by fluorescence in situ hybridization(FISH). We experienced a 15-year-old boy of PW syndrome with diabetes mellitus, who revealed mental retardation, hypogonadism, obesity and microdeletion of chromosome 15 q11-q13 comfirmed by FISH.

Cardiovascular complications are major sources of morbidity and mortality in hypertensive patients. To assess the prevalence of anatomical and functional abnormalities of the heart in such patients, we studied total 67 sujects with systemic hypertension and hypertensive cardiovascular disease by echocardiography. Accordingly normal values of echocardiography from 27 control subjects, we found each significant change(p<0.05). of the septal thickness, left ventricular mass, mitral valve E-F slope and aortic dimension on the both groups, but functional measurements did only show significant change on the hypertensive cardiovascular group in contrast to hypertensive subjects group. The prevalence of the echocardiographic abnormalities on the simple hypertensive subjects group who have no abnormal 12-lead E.C.G. or Chest X-rays are orderly 14 subjects(64%) on the aortic root dimension, 9 subjects (41%) on the left ventricular posterior free-wall thickness and 7 subjects(32%) on the septal thickness. These findings demonstrated a high prevalence of cardiac abnormalities in a population of asymptomatic hypertensive subjects. And these abnormalities can be detected well by echocardiography before they were otherwise apparent.

OBJECTIVE: To investigate outcomes of stimulated IVF cycles in which GnRH antagonist was omitted on the ovulation triggering day. METHODS: A total of 86 women who underwent controlled ovarian hyperstimulation with recombinant FSH and GnRH antagonist flexible multiple-dose protocols were recruited and prospectively randomized into the conventional group (group A) or cessation group (group B). The GnRH antagonist, 0.25 mg/day of cetrorelix, was started when the leading follicle reached 14 mm in diameter and was continuously administered until the hCG triggering day (group A, 43 cycles) or until the day before hCG administration (group B, 43 cycles). The maturity of oocytes, fertilization rate, embryo quality, and implantation and clinical pregnancy rates were evaluated. RESULTS: The duration of ovarian stimulation, total dose of gonadotropins, serum estradiol levels on hCG administration day, and number of oocytes retrieved were not significantly different between the two groups. The total dose of GnRH antagonist was significantly lower in group B than group A (2.5+/-0.9 vs. 3.2+/-0.8 ampoules, p<0.05). There was no premature luteinization in any of the subjects. The proportion of mature oocytes and fertilization rate were not significantly different in group B than group A (70.7% vs. 66.7%; 71.1% vs. 66.4%, respectively). There were no significant differences in the implantation or clinical pregnancy rates. CONCLUSION: Our prospective randomized study suggested that cessation of GnRH antagonist on the hCG administration day during a flexible multiple-dose protocol could reduce the total dose of GnRH antagonist without compromising its effects on pregnancy rates.

Preoperative diagnosis of heterotopic pregnancy is difficult, especially when ectopic component is chronic and the precise effect of chronic tubal pregnancy on coexisting intra-uterine pregnancy or ongoing pregnancy rates is not known. We present the case of heterotopic pregnancy with a chronic tubal pregnancy incidentally diagnosed during term cesarean delivery in infertile woman conceived after ovulation induction using sequential clomiphene citrate and human menopausal gonadotropin, and timed coitus. Chronic tubal pregnancy might not affect the intrauterine gestation or the mother negatively in non-ruptured cases.

Hodgkin's disease (HD) is a hematologic malignancy which shows common features regardless of race, but racial differences may be considered with certain clinical characteritcs. HD in Korea shows somewhat different characteristics when compared to cases in Western countries. We evaluated the clinical and histopathologic characteristics of HD, the outcomes of various chemotherapy regimens, and prognostic factors of HD in Korea. One hundred and five patients with initial histopathologic diagnosis of Hodgkin's disease were retrospectively reviewed 20 years after diagnosis at Yonsei University College of Medicine. Nodular sclerosis was the most common histopathogic subtype (41%) and mixed cellularity was nearly as common (40%). The overall complete remission rate (CR) was 87.6%. The disease-free survival (DFS) and overall survival (OS) rate were 79.2% and 84.8% at 5-years, 70% and 79.2% at 10- and 20-years. There were no significant differences in CR rate and DFS, but OS rates were significantly higher in m-BACOP and ABVD regimen. Univariate analysis revealed that age, B-symptom, ECOG scale, Ann Arbor stage, international prognostic index, and serum beta2-microglobulin level were significant prognostic factors for both DFS and OS. Multivariate analysis demonstrated that age, B symptoms, and ECOG scale were significant prognostic factors for OS only. In conclusion, the survival rates of HD patients in our center were superior to those of previous reports in Korea and Western countries. Considering the higher OS rate and decreased incidence of side effects, the ABVD regimen may be recommended for the initial treatment of Hodgkin's disease.

A patient presented with loss of consciousness and conversion. During an exercise test, catecholaminergic polymorphic ventricular tachycardia (CPVT) resulted in cardiac arrest. He started taking medication (a beta-blocker and flecainide) and an implantable cardioverter defibrillator (ICD) was inserted, but the ventricular tachycardia did not resolve. Left cardiac sympathetic denervation (LCSD) was then performed under general anesthesia, and the patient was discharged on the second postoperative day without complications. One month after the operation, no shock had been administered by the ICD, and an exercise stress test did not induce ventricular tachycardia. Although beta-blockers are the gold standard of therapy in patients with CPVT, thoracoscopic LCSD is safe and can be an effective alternative treatment option for patients with intractable CPVT.

Postpneumonectomy syndrome (PPS) is a rare late complication of pneumonectomy. It occurs more often in children than in adults, and is characterized by respiratory failure resulting from bronchial compression caused by severe mediastinal shift. Various methods have been used to treat PPS, including aortopexy and the insertion of plastic balls, silastic implants, and saline-filled breast prostheses. We describe two cases of PPS corrected with tissue expanders after right pneumonectomy in patients with esophageal atresia.

Chromoblastomycosis is a rare disease in Korea and a total of 7 cases have been reported until now. The causative agents were Fonsecaea pedrosi in 5 cases and Phialophora verrucosa in 1 case. Rhinocladiella (R.) aquaspersa is a very rare etiologic agent and only a few cases of chromoblastomycosis due to this fungus have been reported in the Central and South Americas. We report a case of chromoblastomycosis caused by R. aquaspersa in a 52-year-old woman. The lesion was an erythematous, verrucous plaque on the abdomen, 2x1.3 cm in size, and had developed for 6 months before presentation without a traumatic history. She was successfully treated with itraconazole 200 mg/day for 4 months together with surgical excision without recurrence.

PURPOSE: To investigate the effect of antifreeze protein (AFP) supplementation on ovarian vitrification and transplantation. MATERIALS AND METHODS: In this experimental study, we researched a total of 182 ovaries from 4-week-old ICR mice. The equilibration solution included 20% ethylene glycol (EG), and the vitrification solution included 40% EG, 18% Ficoll, and 0.3 M sucrose. Intact ovaries were first suspended in 1 mL of equilibration solution for 10 min, and then mixed with 0.5 mL of vitrification solution for 5 min. Ovaries were randomly assigned to 3 groups and 0, 5, or 20 mg/mL of type III AFP was added into the vitrification solution (control, AFP5, and AFP20 groups, respectively). The vitrified ovaries were evaluated after warming and 2 weeks after autotransplantation. The main outcome measurements are follicular morphology and apoptosis assessed by histology and the TUNEL assay. RESULTS: A significantly higher intact follicle ratio was shown in the AFP treated groups (control, 28.9%; AFP5, 42.3%; and AFP20, 44.7%). The rate of apoptotic follicles was significantly lower in the AFP treated groups (control, 26.6%; AFP5, 18.7%; and AFP20, 12.6%). After transplantation of the vitrified-warmed ovaries, a significantly higher intact follicle ratio was shown in the AFP20 group. The rate of apoptotic follicles was similar among the groups. CONCLUSION: The results of the present study suggest that supplementing AFP in the vitrification solution has beneficial effects on the survival of ovarian tissue during cryopreservation and transplantation.
