In order to determine the survival rate and prognostic factors of patients with intracranial oligodendroglioma as predictors of survival, a retrospective analysis of a total of 68 cases treated between 1982 and 1992 at our institute was performed. The 5-year and 10-year survival rates were 84.5% and 55.1% respectively while the median survival time was 116+/-5.3 months. The significant factors identified by the univariate analysis included the presence of preoperative seizure, the pre- and postoperative status, the presence of signs of increased intracranial pressure before operation and pathologic grade of the tumors. Factors such as age, types of chief complaints, blood types, the preoperative neurologic deficit, the size of tumor, the enhancement of tumor, cysts in tumor, the extent of removal and the postoperative seizure had no correlations with survival rates. The only significant prognostic factor determined by the multivariate analysis was the pathological grade(p=0.04).

Rhabdomyolysis is a common clinical and laboratory syndrome resulting from reversible skeletal muscle injury, with release of muscle cell contents into the plasma. Cardioversion, and cardiopulmonary resuscitation may produce rhabdomyolysis and myoglobinuria. We report a 5-year-old boy surviving after cardiopulmonary resuscitation and repeated 5 times of cardioversion. He showed elevated serum BUN and creatinine levels, requiring hemodialysis treatment. We had tried 5 times of intermittent hemodialysis, but oliguria was continued and there was no change of serum BUN and creatinine. His urine output was less than 100 cc per day and he showed severe edema and weight gain of 7 kg, and so we started the continuous renal replacement therapy (Prismaflex(R), gambro). After 12 days of continuous venovenous hemodiafiltration (CVVHDF), his urine output recovered and his BUN, creatinine, liver enzyme, creatine kinase, and lactate dehydrogenase levels returned to normal. During the treatment of CVVHDF, he had shown persistent hypercalcemia, and so we changed dialysate and replacement solution from hemosol B0 to calcium free solution. The hypercalcemia was controlled successfully using this calcium free pharmacy-made bicarbonate solution.

BACKGROUND: Waist circumference is one of the key components of metabolic syndrome. Recent studies demonstrated that the reproductive profile was associated with metabolic syndrome in postmenopausal women. This study focused on the association between central obesity and age at first childbirth. It also considered other factors associated with central obesity in postmenopausal women. METHODS: This study was based on the 2013–2015 Korean National Health and Nutrition Examination Survey and involved 3,143 naturally postmenopausal women. These women were divided into three groups according to their age at first childbirth: 19 years or younger (n=252), 20–29 years (n=2,695), and 30 years or older (n=196). Multivariate analysis using logistic regression was performed to evaluate the effects of various reproductive factors, including other confounding factors. RESULTS: During adjustment for confounding factors, in the early age at first childbirth group, odds ratios (95% confidence intervals) for central obesity decreased. In the final model, younger age at first childbirth was not significantly related to central obesity (waist circumference more than 85 cm) in naturally postmenopausal women after adjusting for other confounding factors. CONCLUSION: Younger age at first childbirth was not significantly associated with central obesity after adjustment for confounding factors.

BACKGROUND AND OBJECTIVES: Postnasal drip is one of the most common symptoms of chronic rhinosinusitis (CRS), and is the main cause of chronic cough. To evaluate the effect of upper airway inflammation defined as CRS on lower bronchial airway, we compared the cytology of nasal secretion (NS) and bronchoalveolar lavage fluid (BALF) of normal controls and patients with chronic rhinosinusitis accompanying with and without chronic cough normal controls. MATERIALS AND METHOD: Ten patients of CRS with postnasal drip were selected. Five of them had chronic cough and the others not. Five normal controls were selected. NS collected using Juhn's tymanic tap and BALF collected through fiberoptic bronchoscopy were diluted with dithiothreitol and PBS. These samples were centrifused and then cytospin slide was prepared. The cytology of the slides were evaluated under light microscope after Wright stain. To examine neutrophil activity, nitroblue tetrazolium dye (NBT) test was performd. Statistical analysis was performed using Mann-Whitney Rank Sum W test. RESULTS: In NS, there were no significant differences in the cell populations among coughing, noncoughing, and the normal control group. NBT positivity of coughing (34.2%) and noncoughing (31.5%) groups showed significantly higher than those of controls (8.6%). In BALF of coughing group, the population of macrophages (78.0%) was significantly lower than noncoughing (86.6%) and control (92.8%) groups, and population of lymphocytes (20.8%) was significantly higher than noncoughing (12.6%) and the control (6.4%) groups. In BALF of noncoughing group, the population macrophages was lower and those of lymphocytes were higher than the control group. CONCLUSION: These results suggest that CRS enhances increased local immune responses and decreased phagocytic activity of the lower airway. And chronic cough in patients with CRS is thought to be dependent on individual tolerance to cough provocation, not on aspiration of postnasal drip of discharge.

PURPOSE: Healey divided segment IV of the live as the 'superior portion (IVa) ' and the 'inferior portion (IVb) '. On the contrary, Couinaud suggested that there was no useful purpose in dividing segment IV because of several reasons. Our goal is to evaluate the safety of the 'isolated IVb (inferior) resection of the liver' via performing the dissection of cadavers. METHODS: There were ten total cadavers. Cadaver dissection proceeded with respect to the Glissonian pedicle, the portal vein and the bile duct, respectively. The total number of Glissonian pedicles at segment IV was measured. The distance between the origins of the IVa and IVb branches was measured. Additional pedicles that were known to exist at segment IVa were also evaluated. RESULTS: The mean number of Glissonian pedicles in segment IV, IVa, and IVb was 5 (+/-1.3), 1.6 (+/-7), and 3.4 (+/-0.9), respectively. The mean distance between the origins of the IVa and IVb branches was 5.6 mm (+/-3.9 mm). Two of 10 cases had a very short distance between the origins that were considered as having common origin. Additional pedicles were identified at the Lt. main Glissonian pedicle in all the cases (8 cases: 1 each, 2 cases: 2 each). CONCLUSION: Considering the possible existence of a common origin of segment IVa and IVb Glissonian pedicles, there is the risk that the segment IVa will be injured during 'iso lated IVb resection'. Inevitable ligation of the additional pedicle of segment IVa from the Lt. main Glissonian pedicle can be made during the 'isolated IVb resection'. Therefore, we think that 'isolated IVb resection of the liver' can be safe only when the surgeon divides the branches of segment IVb with meticulous preservation of the IVa branches.

OBJECTIVES: The purpose of this study was to evaluate the efficacy and safety of magnesium sulfate and ritodrine hydrochloride in the management of preterm labor. METHODS: This study was undertaken to assess the clinical efficacy & safety of magnesium sulfate and ritodrine hydrochloride on 120 patients admitted with preterm labor from Jul. 1, 1996 to Dec. 31, 1998. RESULTS: 1. The incidence of preterm labor was showed 6.0~7.7% of total number of delivery. 2. The risk factors of the preterm labor were premature rupture of membrane, severe preeclampsia, previous preterm delivery, twin pregnancy, placenta previa, fetal anomaly, incompetent cervix, placental abruption, and uterine myoma in order, but 28.6% of preterm labor had no apparent risk factors. 3. The days gained in uterus was not statistically different between the magnesium sulfate group and the ritodrine group (p<0.05) but longer in the two groups than the control group. And the delivery time was also not statistically different between the magnesium sulfate group and the ritodrine group (p<0.01) but significantly increased in the two groups than the control group. 4. The rate of complete and incomplete success was similar as 12.5% and 35% (total success rate 47.5%) in the magnesium sulfate group, 7.5% and 45% (total success rate 52.5%) in the ritodrine group but only 2.5% and 27.5% (total success rate 30%) was showed in the control group. 5. The side effects were much more in the ritodrine group than the magnesium sulfate group. The patients requiring second-line therapy were similar in the both groups but the main cause was uncontrolled uterine contraction in the magnesium sulfate group, and intolerable side effects in the ritodrine group. 6. The pulse rate was not statistically different in magnesium sulfate group but markedly increased in ritodrine group (p<0.05). After managements of preterm labor, the serum potassium and ionized calcium level was significantly decreased in the two groups (p<0.05, p<0.01). CONCLUSION: There was not significantly different efficacy and safety of magnesium sulfate and ritodrine hydrochloride in the management of preterm labor.

PURPOSE: Couinaud described segment IV as being equivalent to segments II and III, as the umbilical portion of the portal vein (PV), and its equal branch of segment II, originated from the transverse portion of the PV. On the contrary, Healey suggested the presence of left lateral and medial segments, on the basis of umbilical fissure. Recently, some author have claimed the branch of segment II originated from the distal portion of the ligamentum venosum (LV), and that this branch was not equal to, only a branch of, the umbilical portion. Our goal was to evaluate the surgical anatomy of the left lobe of the liver through dissecting Korean cadavers. METHODS: The number of cadavers dissected totaled 10. PV, its branches, and the LV were dissected and the length of the transverse portion measured. The distance between the origin of the transverse portion and that of the segment II branch were also measured. RESULTS: The branch of segment II originated from the distal portion of the LV in all 10 cases. The length of the transverse portion was 18.8+/-5.8 mm, and the distance between the origins of the LV and segment II branch was 7.0+/-3.1 mm. CONCLUSION: Considering the embryology of the liver, as well as the above result, the umbilical portion and segment II branch were not equal anatomic structures. The umbilical portion and LV are equal anatomic structures. The branch of segment II is only one of the branches of the umbilical portion. We think Healey's classification is more accurate for the left lobe of the liver.

BACKGROUND: The aim of this study was to evaluate the effect of aging on the hemodynamic response to endotracheal intubation during the induction of anesthesia. METHODS: Fifty patients with American Society of Anesthesiologists physical status classification 1 or 2 were enrolled and allocated according to age to either group N (35-44 years, not elderly, n=25) or group E (65-74 years, elderly, n=25). The patients were administered 3 minimum alveolar concentrations of sevoflurane for 5 minutes for the induction of anesthesia. Systolic arterial pressure (SAP) and heart rate (HR) were recorded before (baseline), immediately after (T0), and at 1-minute intervals during the first 4 minutes after endotracheal intubation (T1-T4). RESULTS: SAP increased by 15.4% and 10.8%(p<0.05) from the baseline at T0 and T1, respectively, in group N, and by 21.6%, 17.8%, and 11.8%(p<0.05) from the baseline at T0, T1 and T2 respectively, in group E. The SAP increases at T0, T1 and T2 were significantly greater in group E than in group N (p<0.05). The HR increases at T0 and T1 were significantly greater for group N than for group E (p<0.05). CONCLUSION: We recommend that anesthesiologists vigilantly monitor and attenuate adverse hemodynamic responses for at least 5 minutes after endotracheal intubation especially in elderly patients, particularly because significant systolic hypertension can occur in this age group.

We analyzed 72 items related to serum biochemistry and hematology in 85 specific pathogen-free (SPF) Seoul National University (SNU) miniature pigs aged 1- to 36-months which originated from a Minnesota miniature pig. Almost all examined items were similar between male and female pigs. However, some items such as Cr level, B/C ratio, C.R.F, LDH, LAP and T4 were significantly different between male and female pigs (P<0.05). Thirty four examined items showed age-related changes, and the significant changes were observed in animals less than six months old. The values for BUN, K, uric acid, Ca, Ca++, and Pi were significantly higher in pigs younger than six months of age, which might reflect poor kidney function in young pigs. Additionally, TIBC, UIBC and RDW were significantly higher in young pigs, and RBC, Hb, HCT, MCHC and MCV were significantly lower in young pigs, thus indicating a similar physiology of iron deficiency anemia. These age-related specific phenotypes seemed to be normal, but it should be considered in the long-term experiment using the young pigs. In conclusion, in this study, we defined the normal reference intervals for SPF SNU miniature pigs, and we also determined that there are some physiological differences between the pig genders and ages. This study provides fundamental data for use in experiments involving SPF SNU miniature pigs.

PURPOSE: To diagnose the extent of soft tissue damage with MRI, and to evaluate the relationship between soft tissue damage and a spinal cord injury in an extension injury to the lower cervical spine trauma. MATERIALS AND METHODS: Eighty-one patients who treated surgically for an anextension injury to the cervical spine over the past 5 years, were analyzed. All patients had undergone MRI after the injury, and for the specific grading of soft tissue damage, the grades were defined from grades 1 to 5. RESULTS: The spinal cord injury developed with more than grade 3 soft tissue damage associated with a rupture of the posterior longitudinal ligament (p<0.01). The changes in signal intensity of the spinal cord also developed according to the severity of soft tissue damage (p<0.01). There was no relationship between the soft tissue damage and the spinal cord injury in spinal stenosis (p=0.75). CONCLUSION: The extent of soft tissue damage was diagnosed precisely with MRI, and there was an close relationship between the soft tissue damage and spinal cord injury in the distractive- extension injury to the lower cervical spine trauma.
