The Measurement of CSF glucose and CSF glucose-to-blood glucose ratio is a very useful laboratory test for the differential diagnosis of meningitis. We have observed the change of blood glucose & CSF glucose-to-blood glucose ratio according to the time of blood sampling in 84 patients with aseptic meningitis who had been admitted to the department of pediatrics, Dong Kang hospital from May 1993 to June 1993. The results obtained were as follows: 1) The blood glucose level examined with blood sample drawn just before lumbar puncture and one just after lumbar puncture was 98.29+/-16.20mg/dl and 106.49+/-19.47mg/dl, respectively. 2) The blood glucose level examined with blood sample drawn just before lumbar puncture and one 30 min. after lumbar puncture was 96.47+/-21.52mg/dl and 117.00+/-22.12mg/dl, respectively. 3) The CSF glucose-to-blood glucose ratios examined with blood sample drawn just before lumbar puncture and one just after lumbar puncture was 67.70+/-12.40% and 62.83+/-12.62%, respectively. 4) The CSF glucose-to-blood glucose ratios examined with blood sample drawn just before lumbar puncture and one just after lumbar puncture was 70.10+/-21.77% and 56.35+/-13.75%, reskpectively. We concluded that a simultaneous blood glucose level should be taken just before lumbar puncture.

OBJECTIVE: To evaluate placental causes of fetal death intrauterine (IUFD) bases on placental pathologic findings. METHODS: Retrospective review of 123 placental pathological reports of singleton fetal deaths from 20 weeks of gestation to 41 weeks of gestation. RESULTS: The incidences of maternal causes, fetal causes, inflammatory causes, miscellaneous and unremarkable findings were 45.5%, 28.4%, 16.2%, 23.5%, respectively. The incidence of fetal anomaly was 8.9%. Fetal anomalies were deeply related to fetal cause (P=0.000). Intrauterine growth restriction was significantly associated with maternal causes (P=0.038). CONCLUSION: No pathological guideline regarding placental examination of intrauterine fetal death exists. In future studies, a better definition of fetal death causes and associated placental pathological findings might aid clinicians in counseling, assessing the risk of recurrence and even preventing fetal death in subsequent pregnancies.

BACKGROUND: Platelets can be stored for 3days at 22degrees C in conventional plastic bags plasticizer with di-(2-ethylhexyl)phthalate(DEHP). However, with such a short interval for storage, platelets could not be made easily available for thrombocytopenic patients. In vitro platelet function during 5 days of storage at 22degrees C was studied in a new plastic bag (second generation bag) which contained as plasticizer a tri (2-ethylhexyl)trimellitate and developed in Korea (Boin Medica Co.). METHODS: In vitro function (mean platelet volume, platelet distribution width, pH, platelet aggregation, platelet morphology and swirling phenomenon) was evaluated in 20 units of platelet concentrate at day 0, 2, 5 while mixing in 60 rpm platelet rotator at 22degrees C. RESULTS: At day 5, platelet count, mean platelet volume, platelet distribution width, pH, platelet aggregation, platelet morphology and swirling phenomenon were well maintained. pO2, pCO2 and HCO3- were 65.6mmHg, 43.4mmHg and 12.3mmol/L at day 5, respectively. CONCLUSION: The data indicate that the use of the new platelet storage container will permit satisfactory storage for at least 5 days at 22degrees C.

The purpose of this project was to study the effect of injectable chitosan bead encapsulating calcium sulfate, which makes sustained release of chitosan and calcium sulfate after implantation, on early bony consolidation in distraction osteogenesis of a dog model. Forty five dogs were used for this study. An external distraction device was applied to the mandibular body after vertical osteotomy and the mandibular distraction was started five days after the operation at a rate of 1mm per day up to a 10mm distraction. The experimental group was divided into a control group(I), hyaluronic acid group(II), chitosan group(III), calcium sulfate group(IV), and injectable chitosan bead encapsulating calcium sulfate group(V). Normal saline was injected in the group I. In the group II, a 1-ml volume of hyaluronic acid solution was injected into the distracted area. In the group III, a 1-ml of injectable solution of chitosan mixed with hyaluronic acid was implanted. In the group IV, a 1-ml of injectable solution of calcium sulfate mixed with hyaluronic acid was implanted. In the group V, injectable form of powders of chitosan bead encapsulating calcium sulfate mixed with a 1-ml volume of hyaluronic acid was implanted. Bone mineral density was measured in each group at third and sixth week. The mean three point failure load was measured in each group. In histological findings, new bone was generated in all groups. In the group IV and V, the formation of active woven bone was observed throughout the distracted area at sixth week. The amount of new bone formation in the distracted zone was in the order of the group IV and V, group III and group II, and control group. In conclusion, these findings suggest that injectable chitosan bead encapsulating calcium sulfate appears to be effective in early bony consolidation in distraction osteogenesis.

PURPOSE: Effective hemodialysis for a patient with end-stage renal disease (ERDS) is dependent upon a durable, low-morbidity vascular access. Although It is generally agreed that the distal radiocephalic fistula originally discribed by Brescia and Cimino is the most effective primary access constrruction, no consensus exists regarding primary and secondary alternatives for patients with inadequate of failed rediocephalic prodedures. Many options are available, but the relative value of these alternative operations is unclear. Therefore the place of the basilic vein in secondary acccess construction needs to be assessed. We evaluated if the basilic vein can be used to construct a durable, low-morbidity access. METHODS: A native brachio-basilic arterio-venous fistula with superficial transposition has been performed, for lack of usuable vein on 54 forearm in 47 patients from August 1995 to October 1999 (Male: 15, female: 32) with mean age 51 years (26 to 70 years). RESULTS: The main cause of renal insufficiency were: diabetes 27 (57.4%), hypertensive 19 (40.4%), renal tuberculosis 2 (4.3%) and renal cyst 1 (2.1%). The waiting period before vascular access puncture has been 28 6 days. Eight (17.0%) stenosis has been detected and, forearm and/or hand edema occured in three (6.4%); thrombosis in two (4.3%); bleeding in two (4.3%); pseudoaneurysm in one. Through the follow-up periods of 50 months, the primary patency was 80.9% at 12 months and 78.7% at 24 months. CONCLUSION: The brachio-basilic fistula with superficial transposition of basilic vein is a valuable vascular access for diabetes, female old patients, and can remain an alternative method for even younger patients by avoiding the installation of artificial graft after failed forearm arteriovenous fistula.

This study was performed to compare the dietary food and nutrient intakes according to supplement use in pregnant and lactating women in Seoul. The subjects were composed of 201 pregnant and 104 lactating women, and their dietary food intake was assessed using the 24-h recall method. General information on demographic and socioeconomic factors, as well as health-related behaviors, including the use of dietary supplements, were collected. About 88% and 60% of the pregnant and lactating women took dietary supplements, respectively. The proportion of dietary supplements used was higher in pregnant women with a higher level of education. After adjusting for potential confounders, among the pregnant women, supplement users were found to consume 45% more vegetables, and those among the lactating women were found to consume 96% more beans and 58% more vegetables. The intakes of dietary fiber and beta-carotene among supplement users were higher than those of non-users, by 23% and 39%, respectively. Among pregnant women, the proportion of women with an intake of vitamin C (from diet alone) below the estimated average requirements (EAR) was lower among supplement users [users (44%) vs. non-users (68%)], and the proportion of lactating women with intakes of iron (from diet alone) below the EAR was lower among supplement users [usesr (17%) vs. non-users (38%)]. These results suggest that among pregnant and lactating women, those who do not use dietary supplements tend to have a lower intake of healthy foods, such as beans and vegetables, as well as a lower intake of dietary fiber and beta-carotene, which are abundant in these foods, and non-users are more likely than users to have inadequate intake of micro-nutrient such as vitamin C and iron.
