PURPOSE: Fever plays an important role in causing disturbances in the fluid and electrolyte balance, especially in an immature brain. Recently, it was reported that hyponatremia enhanced the susceptibility of febrile convulsions in children and increased the risk of repeat convulsions during the same febrile illness. We studied the relationship between hyponatremia and febrile convulsions. METHODS: Blood samples for electrolyte measurements were taken from 52 children who visited Chosun University Hospital between June 1997 and July 1998(patient group I: simple febrile convulsion, patient group II: repeated febrile convulsions). We checked serum electrolytes in groups of age-matched controls(control group I: no fever, no convulsion, control group II: fever only, control group III: non-febrile convulsion). The results were analyzed by Student's t-test and ANOVA test. RESULTS: The mean serum sodium level of both patient groups(136.8+/-2.3mmol/L) was significantly lower when compared to all control groups(control groupI: 140.7+/-2.5mmol/L, control group II: 139.7+/-3.1mmol/L, control group III: 139.7+/-4.6mmol/L)(P<0.05). The mean serum sodium levels were not different between each of the control groups(P>0.05). The mean serum sodium level in the group with repeat convulsions(136.8+/-2.4mmol/L) was not significantly lower than the mean in the group with simple febrile convulsions(136.7+/-2.2mmol/L). There was no statistical relationship between the level of serum sodium and the probability of repeat convulsions(r=0.19, P>0.05). CONCLUSION: Our results show that low serum sodium concentration may increase the risk of febrile convulsions. However, there is no statistical relationship between the level of serum sodium and the probability of repeat convulsions. These findings warrant further studies on the relationship between the control of electrolyte levels and seizures.

OBJECTIVES: To determine if hysterectomy with or without ovarian preservation is asso-ciated with obesity in premenopausal women. METHODS: 581 women for routine check up from Jan. 1985 to Dec. 1995 in the depart-m ent of Gynecology at Korea Veterans Hospital were included. The obesity was evaluated by BMI(body mass index) scores. 80% of hysterectomy were confirmed from the hospital records. The age, weight, height, blood pressure, menstr- ual history, history of DM and hypertension, social history of alcohol and smoking and other cardiovascular risk factors such as cholesterol, HDL-cholesterol, triglycerides were checked. The 248 women with natural postmenopausal status before hysterectomy, taking hormonal replacement therapy after hysterectomy and having performed hysterectomy due to malign- ancy were excluded. RESULTS: All women performed hysterectomy were in premenopausal status in this study. Therefore, the final numbers of subjects included in the analysis was 333. Hysterectomy wit- hout ovarian preservation were performed in 58 cases and hysterectomy with ovarian pres- ervation were in 57 cases. The 218 premenopausal cases which did not performed hystere- ctomy were considered control group. BMI scores were higher in cases without ovarian pres- ervation than with ovarian preservation. And BMI score was associated with the postoper- ative duration in hysterectomy with ovarian preservation. CONCLUSIONS: We suggest that hysterectomy without ovarian preservation in premeno- paussal women were associated with increased obesity, especially BMI scores.

BACKGROUND: Major respiratory problems during spinal anesthesia occur due to several causes, particulary, high spinal block, use of sedatives or opioids, and underlying cardiopulmonary diseases. Pulse oximetry has prevented most of these problems, but has not provided rapid and accurate information of the patient's ventilation. We measured end-tidal CO2 tension via the side-stream capnometer with a small rubber cannula and investigated its effectiveness in ventilatory monitoring under spinal anesthesia. METHODS: Nineteen patients were involved in this study. We performed spinal anesthesia with 0.5% heavy marcaine 12 mg (L3-4 interspace). After fixation of spinal sensory blockade level, 0.035 mg/kg of midazolam was administered intravenously to sedate the patient. A polyvinylchloride catheter with a rubber extending nasal cannula was used for sampling of respiratory gas. PETCO2 was measured at 15 minutes after spinal anesthetic injection (before sedation), and at 5 minutes after midazolam injection (after sadation). Arterial CO2 tension was also measured during PETCO2 measurement. RESULTS: There was no correlation of spinal maximal sensory blockade level with repiratory rate, PaCO2 and PETCO2. Linear regression analysis of arterial vs. end-tidal CO2 yielded a slope of 0.92, r=0.81 and p<0.001 (before sedation), and a slope of 0.98, r=0.79 and p<0.01 (after sedation). Arterial to end-tidal differences were 4.2+/-2.8 mmHg (before sedation) and 4.3+/-3.0 (after sedation), but there was no significant difference in comparing them with each other. Conclusions : We conclude that this form of PETCO2 measurement is useful in continuous, noninvasive monitoring of ventilation in patients under spinal anesthesia.

Rapid-eye-movement (REM) sleep behavior (RBD) is a form of REM sleep motor dyscontrol characterized by complex, vigorous, and frequently violent behaviors without atonia during the REM sleep. The motor dyscontrol may include not only cataplexy and sleep paralysis but alto periodic limb movements during REM and non-REM sleep. We examined two patients with charateristic episodes of behavioral manifestations during the REM sleep as well as with other sleep disorders such as narcolepsy and periodic limb movement disorder. The one patina was an 18 year-old man who had childhood-onset RBD associated with narcolepsy since 10 years old. The polysomnographic studies showed excessive augmentation of chin EMG and 6 attacks of violent behavior during REM sleep. He also complained of cataplexic symptomes. Multiple sleep latency tests (MSLT) showed four sleep onset REMs and two episodes of violent behavior during the REM sleep. The other patient was a 74 year-old man who complained of violent behaviors during the REM sleep and polysomnographic studies showed excessive augmentation of chin EMG during the REM sleep and periodic leg movements for 24min. And 14sec. During the sleep. We report two patients with RBD which were associated with narcolepsy, and periodic limb movememt disorder irrespectively, suggesting that RBD, narcolepsy and periodic limb movement disorder could occur coincidently and be understood as a motor dyscontrol during REM sleep.

BACKGROUND: We investigated the prevalence of dementia and mild cognitive impairment (MCI) and their risk factors in an urban community-dwelling elderly people over 65 years old. METHODS: A two-phase investigation was performed from January 2010 to December 2011. In Phase I, all subjects (n=9,485) responded to the Korean version of the Mini-Mental State Examination (K-MMSE). Based on the K-MMSE score the subjects were classified into two groups ('Normal' and 'Cognitive decline'). In Phase II, cognitive decline subjects were diagnosed as dementia or MCI according to the neuropsychological tests and doctor's interview. We also surveyed the socioeconomic and medical factors in Normal, Dementia and MCI groups. And we compared and analyzed the socioeconomic and medical risk factors by multiple logistic regressions in Dementia and MCI group. RESULTS: The prevalence of dementia and MCI was obtained 5.4% and 4.3%, respectively. Old age, alcohol intake, living together, low economic status, jobless in the past, diabetes mellitus, previous stroke, lower BMI and family history of dementia were associated with the increased dementia risk. Higher education, hypertension and physical activity were associated with the decreased dementia risk. And old age, alcohol intake, higher education, previous stroke, lower BMI and physical activity were common risk factors in MCI group. CONCLUSIONS: The prevalence of dementia and MCI was obtained much lower than previous reports. Dementia and MCI patients had common socioeconomic and medical risk factors. It is also important to control the risk factors earlier to prevent the increase of patients in dementia. And in order to prove the hypothesis that early control of the risk factors can decrease the occurrence of dementia, the further prospective studies are needed.

PURPOSE: The purpose of the present retrospective study was to report the clinical and radiological results of 31 total hip arthroplasties of 28 patients with bony ankylosed hip. MATERIALS AND METHODS: Conversions to cementless total hip arthroplasty between August 1983 and May 1999 were reviewed after followups ranging from 3 years 1 month to 18 years. The mean age of the patients at the time of operation was 35.0 years. The mean duration of the ankylosis was 15 years 7 months. RESULTS: At the time of the last follow-up, the mean arc of flexion was 84.6 degrees. The mean Harris hip score improved from 47.7 to 84.9. There were no significant differences in clinical results according to the type and duration of ankylosis. Radiographs showed one acetabular loosening, six acetabular osteolysis and five femoral osteolysis. In cases of osteolysis, the average wear rate was 0.28 mm/year. CONCLUSION: The conversion of bony ankylosed hip to a cementless total hip arthroplasty revealed a favorable outcome, and the risk of failure was found to be unrelated to the type and the duration of ankylosis. However, since some patients show excessive wear with osteolysis, polyethylene liner wear will be of critical importance in terms of long-term results.

Since it was reported that incipient enamel caries can be recovered, previous studies have quantitatively evaluated that enamel artificial caries have been remineralized with fluoride, showing simultaneously the increase of width of surface layer and the decrease of width of the body of legion. There is, however, little report which showed that remineralization could occur without fluoride. In addition, the observations on the change of hydroxyapatite crystals also have been scarcely seen. In this study, enamel caries in intact premolars or molars was induced by using lactic acidulated buffering solutions over 2 days. Then decalcified specimens were remineralized by seven groups of solutions using different degree of saturation (0.212, 0.239, 0.301, 0.355) and different pH (5.0, 5.5, 6.0) over 10 days. A qualitative comparison to changes of hydroxyapatite crystals after fracturing teeth was made under SEM (scanning electron microscopy) and AFM (atomic force microscopy). The results were as follows: 1. The size of hydroxyapatite crystals in demineralized area was smaller than the normal ones. While the space among crystals was expanded, it was observed that crystals are arranged irregularly. 2. In remineralized enamel area, the enlarged crystals with various shape were observed when the crystals were fused and new small crystals in intercrystalline spaces were deposited. 3. Group 3 and 4 with higher degree of saturation at same pH showed the formation of large clusters by aggregation of small crystals from the surface layer to the lesion body than group 1 and 2 with relatively low degree of saturation at same pH did. Especially group 4 showed complete remineralization to the body of lesions. Group 5 and 6 with lower pH at similar degree of saturation showed remineralization to the body of lesions while group 7 didn't show it. Unlike in Group 3 and 4, Group 5 and 6 showed that each particle was densely distributed with clear appearance rather than crystals form clusters together.
