OBJECTIVE: To investigate the morphometric characteristics of the pituitary gland and diaphragma sellae in Korean adults. METHODS: Using the 33 formaline fixed adult cadavers (23 male, 10 female), the measurements were taken at the diaphragma sellae and pituitary gland. The authors investigated the relationship between dura and structures surrounding pituitary gland, morphometric aspects of pituitary gland and stalk, and morphometric aspect of central opening of diaphragma sellae. RESULTS: The boundary between the lateral surface of pituitary gland and the medial wall of cavernous sinus was formed by the thin dural layer and pituitary capsule. The pituitary capsule adherent tightly to the pituitary gland was observed to continue from the diaphragma sellae. Mean width, length, and height of the pituitary gland were 14.3 +/- 2.1, 7.9 +/- 1.3, and 6.0 +/- 0.9 mm in anterior lobes, and 8.7 +/- 1.7, 2.9 +/- 1.1, and 5.8 +/- 1.0 mm in posterior lobes, respectively. Although all dimensions of anterior lobe in female were slightly larger than those in male, statistical significance was noted in only longitudinal dimension. The ratio of posterior lobe to the whole length of pituitary gland was about 27%. The mean thickness of pituitary stalk was 2 mm. The diaphragmal opening was 5 mm or more in 26 (78.8%) of 33 specimen. The opening was round in 60.6% of the specimen, and elliptical oriented in an anterior-posterior or transverse direction in 39.4%. CONCLUSION: These results provide the safe anatomical knowledge during the transsphenoidal surgery and may be helpful to access the possibility of the development of empty sella syndrome.

PURPOSE: The osmolar gap increases in proportion to the ethanol level. Some previous studies have shown that the correlation between the osmolar gap and the ethanol level is weak in trauma patient by using an indirect comparison with other patients. We conducted a direct comparison of the correlation of the osmolar gap to the ethanol level between trauma patients and non-trauma patients. We also analyzed the accuracy of the estimated ethanol level between the two groups. METHODS: The research candidates were adult patients who had visited the emergency department of our hospital from December 2003 to November 2008. By using a retrospective chart review, we classified them into three subgroups: non-trauma without shock, trauma without shock, and trauma with shock. In each group, we compared the correlation between the osmolar gap and the measured ethanol level, and we analyzed the accuracy of the estimated ethanol level by using Lin's concordance correlation coefficient. RESULTS: Four hundred forty-seven patients were enrolled in this study. For correlation of the osmolar gap and the measured ethanol level, Pearson's correlation coefficient was 0.916 in all patients, 0.939 in non-trauma without shock patients, 0.917 in trauma without shock patients, and 0.844 in trauma with shock patients. In the analysis of the accuracy of the estimated ethanol level by using Lin's concordance correlation coefficient, the accuracy in trauma with shock patients was lower than that in non-trauma without shock patients. CONCLUSION: We found that the correlation between the osmolar gap and the measured ethanol level in the patient group with trauma was lower than it was in the patient group without trauma. Moreover trauma patients with shock had a lower accuracy of the estimated ethanol level than non-trauma patients.

The arteriovenous fistula and cirsoid aneurysm, characterised by abnormal arterial and venous connections with grossly dilated and expansile mass of vessels, may predispose to dramatic complications. Cirsoid aneurysms of the scalp have been reported to be difficult to remove. Multiple treatment schemes have been described and, as yet, no standard form of therapy exists. Three cases of cirsoid aneurysms of the scalp are presented. Each of them was treated with embolization and total excision after ligation of the feeding arteries. All of them were well cured.

OBJECTIVE: Maternal anemia is one of the most common hematologic disorders of the child-bearingmothers. However the role of maternal anemia in the etiology of preterm delivery and adverse pregnancyoutcomes remains a source of controversy. The aim of this study was to determine the effects of maternalanemia on the preterm birth and the adverse pregnancy outcomes. STUDY DESIGN: A total of 1,010 women aged 19~44 years, who admitted to our hospitalfor the delivery between December 1994 and October 1995, were recruited into a hospitalbaed case-control study design. 259 women complicated by maternal anemia(cases) werecompared with 751 women without maternal anemia(controls). Multiple logistic regressionanalyses were performed to control for the effects of other potentially confounding factors,including maternal age, body mass index, previous term delivery, previous preterm deliveryand previous abortion. In all logistic regression analyses odds ratio and 95% confidenceintervals were calculated. RESULTS: The prevalence of maternal anemia(hemoglobin<10g/dl) was 25.6%. Therewas a positive linear relationship between the prepartum hemoglobin concentration and thepostpartum concentration. There was no significant differences of the incidence of pretermbirth and the neonatal morbidity, such as poor Apgar scores, fetal distress, congenitalanomaly, birth trauma, admission to neonatal intensive care unit, resuscitation and sepsisbetween case and control groups. Small for gestational age and low birth weight were associatedwith an somewhat decreased risk of maternal anemia and large for gestational age, notmacrosomia, was associated with an 70% increased risk of maternal anemia at the time ofdelivery. Maternal anemia was associated with 6.5 fold increases in the risks of postpartumbleeding, 8.5 fold increases in the postpartum transfusion and 80% increases in the puerperalfever respectively. CONCLUSIONS: Maternal anemia was not associated with increased risks of preterm birthand the neonatal morbidty. However there was a significant relationship between maternalanemia and postpartum maternal morbidity, such as postpartum bleeding, postpartum transfusionand puerperal fever.

We present a series of 42 patients with the lateral ventricular mass lesions who underwent operative removal between 1979 and 1992 at the Seoul National University Hospital. These lesions included 29 tumors, 10 benign cysts and 3 arteriovenous malformations. There were 20 lesions in the trigone, 14 in the frontal horn, 6 in the body, and 2 in the temporal horn. Together with the age of the patient, the location in the lateral ventricle and the CT or MR patterns, the range of the differential diagnosis of the lesions can be narrowed. The mass were removed by various surgical approaches;11 by the middle frontal gyrus, 10 by the superior parieto-occipital, 13 by the middle temporal gyrus, 4 by the anterior transcallosal, 2 by the posterior transcallosal and 3 by the combined approaches. The superior parieto-occipital approach left postoperative morbidities in 64% and other approaches in 20 to 25% of the cases. These morbidities included hemiparesis, hemianopsia, aphasia, memory distubance and seizure. Most hydrocephalus disappeared without the shunting procedure after removal of the lateral ventricular mass. The high frequency of postoperative complications in the superior parieto-occpital approach require meticulous consideration in the selection of this approach.

PURPOSE: Advanced techniques now make it possible to remove considerable amounts of subcutaneous adipose tissue more safely with minimum blood loss. However, few have analyzed the metabolic consequences of liposuction. The purpose of this study was to identify the early effects of the surgical removal of subcutaneous fat on metabolic changes in patients who have undergone liposuction. METHODS: Nineteen patients were evaluated from June 2005 to December 2005. Preoperative body weight, serums levels of lipids, apolipoprotein A1, dehydroepiandrosterone(DHEA), uric acid, insulin, and glucose were evaluated. Insulin resistance was determined using the homeostasis model assessment of insulin resistance (HOMA-IR), which is based on fasting glucose and insulin concentrations. All of these data were remeasured in 1 and 4 weeks postoperatively. Tumescent fluid was infiltrated using the superwet technique. The liposuction device used was a Liposlim(R) power-assisted unit. RESULTS: Average volumes of infiltrate and aspirate were 3,268mL and 2,892mL, respectively. Results in 1 week postoperatively demonstrated a significant difference in high-density lipoprotein(HDL) cholesterol, apolipoprotein A1, insulin, and HOMA-IR levels. However, all values were within normal limits and returned to baseline in 4 weeks postoperatively. CONCLUSION: This study provides little to support the presumed therapeutic effect of liposuction. And, it is unclear whether liposuction can prevent or be used to treat the metabolic complications of obesity. However, the results of the present study lead us to believe that liposuction is a metabolically safe procedure.

BACKGROUND/AIMS: Considering the incidence of prevailing hepatitis B virus (HBV) genotypes in neighboring nations, the predominance of genotype C in Korea is exceptional and needs to be confirmed by nationwide investigation. METHODS: A total of 510 HBsAg (+) or HBeAg (+) serum samples was collected from subjects in several cities and harbors throughout the Korean peninsula for genotype (A-G)-specific multiplex PCR analysis. Another 40 serum samples from chronic HBV carriers from Iksan city were selected for sequencing of the entire HBV genome. Phylogenetic analysis was performed with 22 whole genomic sequences of Korean HBV strains enrolled in GenBank. RESULTS: An amplicon was found in 377 specimens and genotype C occupied 98.1% (370 cases); none of the other genotypes were found. A mixed pattern of genotypes B and C was seen in seven specimens (1.9%), of which five were tested using PCR targeting the X fragment; no genotype B bands were found. With the exception of 1 case, which was subgenotype A2, whole sequences of Korean HBV strains (n=62) belonged to subgenotype C2. CONCLUSIONS: The prevailing HBV genotype in Korea is C2; the other genotypes occur only rarely. Future studies should include confirmation of the detection of genotypes other than C.
