We experienced one case of severe pituitary dwarfism in a 10 years old female girl. Magnetic resonance image (MRI) revealed transection of the pituitary stalk stalk with the formation of high intensity ectopic posterior lobe located at the median eminence and agenesis of an anterior lobe of pituitary gland. The serum growth Hormone (GH) response to clonidine and L-dopa revealed severe GH deficiency. The patient had responses to TRH, normal TSH and partial prolactin response, respectively. There was not response LH and FSH to GnRH. The morning cortisol concentration and serum T4 concentration were decreased below the normal range. These findings and no hyperprolactinemia suggested the presence of a vascular connection between the pituitary gland and hypothalamus, which is not visible on MRI. Sofar, the primary cause of idiopathic pituitary dwarfism in many patients is injury to hypothalamus by perinatal insults. In this patient, there was no history of perinatal insults and postnatal head trauma but transection of the pituitary stalk. We report a case of severe pituitary dwarfism due to agenesis with brief review of related litereature.

PURPOSE: We performed this study to evaluate the changes of gallbladder ejection fraction (GBEF) in diabetic patients with or without autonomic neuropathy. MATERIALS AND METHODS: This study included 37 diabetic patients (25 women, 12 men, mean age 51 years) and 24 normal controls (10 women, 14 men, mean age 38 years). After intravenous injection of 185 MBq of 99mTc-DISIDA, serial anterior abdominal images were acquired before and after fatty meal. Regions of interest were applied on gallbladder and right hepatic lobe on 60 and 90 minute images to calculate GBEF. RESULTS: GBEF was significantly reduced in diabetes with autonomic neuropathy (43+/-12.3%) and without autonomic neuropathy (57.5+/-13.2%) compared with normal controls (68+/-11.6%, p <0.05). And also, GBEF was significantly reduced in diabetes with autonomic neuropathy compared with diabetes without autonomic neuropathy (p <0.05). Fasting blood glucose level, age, sex, hemoglobin A1c, body mass index, serum lipid level were not different in these two diabetic patient groups (p>0.05). When 50.2% of GBEF was used as the criteria for diabetic autonomic neuropathy, the sensitivity and specificity were 80%, 76.5%, respectively. The area under receiver operating characteristic curve was 0.846. CONCLUSION: GBEF of diabetic patients with autonomic neuropathy was significantly reduced than that of diabetic patients without autonomic neuropathy.

BACKGROUND: Exercise testing is an importnat diagnostic and prognostic procedure in the assessment of patients with ischemic heart disease. But standard ST-segment depression criteria was not high enough to estimate coronary srtery disease. Recently, the heart rate adjustment of ST segment depression, ST segment/heart rate slope and index, have been proposed as a more accurate criteria for diagnosing significant coronary artery disease. The objective of this study was to compare the discriminating power of proposed ST segment/heart rate slope and index with that of a standard method of assessing exercise-induced ST segment depression for estimating coronary artery disease. METHODS: Sixty nine patients with ischemic heart disease were studied with exercise treadmill testing and coronary angiography. Computer-measured ST-segment amplitudes were obtained and analysis of the heart rate-adjusted ST segment depression(ST/HR slope and big up tri, Delta ST/HR index) was done. The sensitivity, specificity, and extent of coronary artery disease on each criteria were compared. RESULTS: 1) The sensitivity of big up tri, Delta ST/HR index partition of 1.6uV/beats/min was slightly higher(83%) and the specificity of ST/HR slope partition of 2.4uV/beats/min was higher(87%) than the standard exercise electrocardiographic criteria. 2) Early onset of ischemic ST-segment depression, profound ST-segment depression(> or =2mm), and downsloping ST-segment were associated with more extensive coronary artery disease. 3) On ST/HR slope, no CAD was 1.7+/-0.26uV/beats/min, one vessel disease was 2.6+/-0.34 uV/beats/min, two vessel disease was 2.7+/-1.36uV/beats/min, one vessel disease was 2.8+/-0.35uV/beats/min, and on big up tri, Delta ST/HR index, no CAD was 1.8+/-0.38uV/beats/min, one vessel disease was 2.8+/-1.36uV/beats/min, two vessel disease 3.4+/-1.44uV/beats/min, and three vessel disease was 3.7+/-2.95uV/beats/min. The increment of ST/HR slope and big up tri, Delta ST/HR index were associated with the coronary artery disease and its severity, but the correlations were not high enough. CONCLUSION: The heart rate adjustment of ST segment depression was not high enough for improved detection of coronary artery disease, compared with standard ST-segment depression criteria. But these indexes can be improved the clinical usefulness of the treadmill exercise test for coronary aretry disease.

BACKGROUND/AIMS: The transmission routes of HCV infection were not determined in the half of the HCV infected patients. So intrafamilial personal contact, sexual contact, vertical transmission and some vectors are supposed as a route of HCV infection. We investigated the prevalence of anti-HCV positivity in healthy Korean children and compared with the data from the healthy adults whether the vertical transmission is feasible. METHODS: Serum samples from 2,080 children in 8 elementary schools were tested for serum aminotransferases, hepatitis B viral markers by radioimmu- noassay, and anti-HCV by the third generation EIA. Sera from anti-HCV positive children were tested for HCV-RNA by RT-PCR. Six months later, same tests were repeated. RESULTS: Anti-HCV was positive in 17 children among 2,080(0.82%). Among 17 anti-HCV positive children, HCV-RNA was detected only in one case and the HCV genotype was type II by Okamotos classification. Anti-HCV was tested again in 7 of 17 anti-HCV positive children after 6 months later and all of these children were anti-HCV positive and additional 3 of 19 family members were anti-HCV positive. But HCV-RAN was not detected in alL CONCLUSION: Anti-HCV positive rate in children was 0.81%.

Rectus sheath hematoma is an uncommon cause of acute abdomen, caused by a tear in deep epigastric vessels or its branches. It occurs spontaneously, after trauma or surgery. Rectus abdominus myonecrosis is a life threatening complication of rectus sheath hematoma. We report a case with fatal rectus sheath hematoma complicated by rectus abdominus myonecrosis caused by ischial fracture in a chronic active rheumatoid arthritis patient.

BACKGROUND: Hydroxyethyl starches (HES) solutions are the most commonly used colloids for treating hypovolemia and expanding plasma, but they compromise platelet function and reduce the level of coagulation factors. As opposed to other HES solutions, 6% HES (130/0.4) solution may influence hemostasis minimally due to its low mean molecular weight and degree of substitution. This study was designed to establish the safety of HES (130/0.4) infusion in the presence of massive blood loss. METHODS: Twelve healthy adult patients scheduled for spine surgery were enrolled in this study. Before the induction of general anesthesia, all patients underwent acute normovolemic hemodilution (ANH), which was independent of surgical stress and other confounding factors. While approximately 30% of the estimated blood volume was procured, the blood deficit was replaced with the same volume of 6% HES (130/0.4) solution. Hematocrit, platelet count, factor VIII activity and plasma fibrinogen concentration were determined and thrombelastography was performed to evaluate the hemodilution effect and hemostatic impairment before and after ANH. Statistical testing was conducted to analyze the effect of HES on hemostasis. RESULTS: Hematocrit, platelet count, factor VIII activity and plasma fibrinogen concentrations decreased significantly (P < 0.05 respectively) after the ANH. On comparing pre-ANH and post-ANH thrombelastographic findings, the R time was shortened (P = 0.045), the alpha angle increased (P = 0.01) and MA decreased (P = 0.003) significantly. CONCLUSIONS: Summarizing, little effect was observed on the hemostatic system when 20 ml/kg of 6% HES (130/0.4) solution was infused. HES (130/0.4) solution as used to maintain normovolemia during ANH may be free from bleeding risk.

BACKGROUND: Lipoprotein(a)[Lp(a)], an independent risk factor for athrosclerosis, consist of low density lipoprotein like particle and specific glycoprotein, apolipoprotein(a). The levels of Lp(a) are mainly determined by the genetic pleomorphism of apolipoprotein(a) and has been though not to be influenced by age, sex and other biochemical parameters. Recent reports have shown that the concentrations of Lp(a) are correlated with age in women. The purpose of this study was to invastigate the association of Lp(a) concentration with sex and age. METHODS: The concentrations of Lp(a) were measured in 3,707 women and 389 men, free of diseases and medications known to affect the lipid levels. Plasma Lp(a) concentration were measured by commercial radioimmunoassay kit and other lipid profiles by conventional method. RESULTS: In female, median Lp(a) concentration increased with age till the early sixth decade (P=.0000) and then decreased. If peri- and postmenopausal women were excluded in the fifth decades, the relation between age and Lp(a) disappeared. In male, Lp(a) concentration were not associated with age. Median Lp(a) concentrations were higher in females than in males in the fifth(p=.0039) and the sixth decades(p=.0007), The difference became negligible after the exclusion of peri- and postmenopausal woman in the fifth decade. CONCLUSION: The concentrations of Lp(a) were corrected with age only in female. Females had higher levels than males in the fifth and the sixth decades. The relations are thought to be nither due to aging process nor sex but due to postmenopausal increase of Lp(a).

This study was undertaken to investigate the effects of cyclophosphamide (CY) on dendritic cells (DCs) and ED2 positive tissue macrophages in adult rat lymphoid and non-lymphoid organs. A single dose of CY (150 mg/kg) was administered to Sprague-Dawley rats by intraperitoneal injection. After the rats were sacrificed in groups of three at 1 day, 3 days, 1 week, 2 weeks and 1 month, the tongue, heart, urinary bladder, thymus, spleen and cervical lymph nodes were removed. The immunocytochemical characterization of the cells was carried out using the monoclonal antibodies OX6, OX62 and ED2 in cryostat-cut sections. CY elicited a decrease in number of intraepithelial and interstitial DCs in urinary bladder and in number of interdigitating DCs in all the lymphoid organs examined in this study, whereas CY did not cause any alteration in the number and distribution pattern of dendritic cells in tongue and hearts. CY increased the size and number of tissue macrophages in all the organs examined in this study. Most of these features began to appear from the first day and reached the maximun on the third and seventh day, but two weeks after CY administration, these phenomena declined. In conclusion, CY has differential effects on the rat DCs and macrophages and also on the subpopulations of DC according to the location and the functional state.

PURPOSE: Paradoxical embolism due to the presence of patent foramen ovale(PFO) is a well-established possible mechanism of ischemic stroke of unknown origin, and the closure of PFO seems to be a kind of most effective method of the prevention of stroke recurrence. We report the initial and intermediate-term result of transcatheter closure of PFO associated with paradoxical embolism leading to cryptogenic transient ischemic attack or cerebrovascular accident using the Amplatzer(R) PFO Occluder. METHODS: From January 2003 through May 2005, 10 patients with PFO(4 male, 6 female) with history of at least 1 cryptogenic transient ischemic attack or cerebrovascular accident underwent percutaneous transcatheter closure of PFO using Amplatzer(R) occluder assisted by transesophageal echocardiography(TEE). All procedure were performed under general anesthesia and assisted by TEE. RESULTS: In all patients, the implantation procedure was successful and no significant complication was observed(in one case, peri-interventional ST-segment elevation observed). During the follow-up period of mean 13.1 months(range, 1-28 months), no recurrence of neurologic episode were observed and there was no residual shunt through PFO. CONCLUSION: We were able to implant the device without significant complication in all our patients and close PFO effectively. No recurrence of neurologic episode were observed. We conclude that in this initial and intermediate-term follow up, the transcatheter closure of PFO associated with paradoxical embolism using the Amplatzer(R) PFO Occluder is a safe and effective method in prevention of stroke recurrence and there is no significant adverse effect until now. And this procedure may be the treatment choice in patients with the high risk of recurrence ischemic attack. However, in this study, the number of patients included[5 patients(50%) had multiple thromboembolic events] is small and follow-up period is not long. So, we need more clinical cases and long-term clinical follow-up.
