Osteoporosis is a metabolic bone disease characterized by decrease of bone matrix, resulting in generally reduced bone mass, and the diagnosis and grading of progression are assessed by many methods. There are Singh Index as a simplest method, for grading the trabecular pattern of the femur in pelvis anteroposterior X-ray, and the recently developed Dual Photon Absorptiometry which measures the bone mineral contents in the lumbar spine(L2-L4), femur neck, Ward's triangle and trochanteric area. Study for correlation between the Singh index and bone mineral contents measurements by Dual Photon Absorptiometry was performed in 36 normal Korean persons and 35 persons with osteoporosis. The results and conclusion were as follows; 1. A significant difference in bone mineral density at each area was noted between the control group and osteoporosis group. 2. A significant difference in Singh Index at each area was noted between the control group and osteoporosis group. 3. Positive correlation was noted between the mineral density and Singh Index. 4. We think Singh Index is a useful method in the diagnosis and grading of progression of osteoporosis.

OBJECTIVES: To investigate the frequency and clinical characteristics of premenstrual syndrome(PMS)/premenstrual dysphoric disorder(PMDD) in high school students, and determine the correlates of PMS/PMDD in association with comorbid depression and anxiety. METHODS: A total of 1688 students were recruited from 5 high schools in Seoul, Korea. Subjects completed the questionnaire composed of scales to measure premenstrual symptoms, depression, and anxiety, as well as sociodemographic and reproductive variables. Subjects were categorized into 3 groups by using the Premenstrual Symptom Screening Tool(PSST) to determine the frequency and clinical characteristics of PMS/PMDD. Multivariate logistic regression was used to identify the correlates of PMS/PMDD. RESULTS: The frequency of moderate to severe PMS and PMDD was 20.1% and 6.4%, respectively. Irritability (78.8%), fatigue(76.4%), and emotional sensitivity(69.8%) were common premenstrual symptoms, and functional impairment in academic performance(67.1%) was dominant. Dysmenorrhea[odd ratio(OR)=3.68, 95% confidence interval(CI) 2.45-5.55], family history of PMS(OR=1.91, 95% CI 1.35-2.71), and use of oral contraceptive (OR=1.85, 95% CI 1.16-2.94) were associated with the increased risk of PMS/PMDD after adjustment for depression and anxiety. Negative attitude to menses(OR=15.60, 95% CI 3.61-67.42) was associated with the increased risk of PMS/PMDD, particularly in subjects without depression and anxiety. CONCLUSIONS: PMS was common, as the frequency of PMS more than moderate severity including PMDD exceeded 25%, and disrupted daily functioning in adolescents. PMS is associated with various sociodemographic and menstrual characteristics, and these associations are affected by comorbid depression and anxiety.

Cerebral CT findings were described in twenty-six cases with the late sequelae of acute carbon monoxidepoisoning and were compared with the neurological symptoms and signs. The CT findins include symmetricalperiventricular white matter low density in five cases, globus pallidus low denstiy in six cases, ventriculardilatation in seven cases, ventircular dilatation and sulci widening in three cases, and normal findings in tencases. Only one case showed low densities in both periventricular white matter and globus pallidus, Late sequelaeof the interval form of carbon monoxide poisoning were clinically categorized as cortical dysfunction,parkinsonian feature, and cerebellar dysfunction. The severity of the clinical symptoms and sings of neurologialsequelae is generally correlated with presence and multiplicity of abnormal brain CT findings. But CT. Anothercase showing small unilateral low density of globus pallidus had no parkinsonian feature but showed mild corticaldysfunction.

In the treatment of malleolar fracture, anatomical reduction and rigid internal fixation are essential to prevent the complications such as infection, malunion or nonunion, traumatic arthritis, skin necrosis and joint contracture. But it is often difficult to obtain rigid fixation for medial malleolar fracture because of its comminution or thin cortex with osteoporosis. Generally, two operative methods are available for medial malleolar fracture, which are malleolar lag screw fixation and tension band wiring. The purpose of this paper is to analyze which operative method is better for anatomical reduction and rigid fixation and has less postoperative complications for medial malleolar fractures. From March 1992 through March 1995, 88 patients had undergone surgical intervention for medial malleolar fractures. The patients were divided into 2 groups according to operative method for medial malleolar fracture. For one group, malleolar lag screw together with or without a K-wire was used in 48 patients, and for the other group, tension band wiring was used in 40 patients. The average follow-up periods were 14 months in screw fixation group and 13 months in tension band wiring group. The average union time were 15.4 weeks (8-17 weeks) in screw fixation group and 12.2 weeks (6-15 weeks) in tension band wiring group. 27 cases (56%) showed excellent result in screw fixation group and 30 cases (75%) in tension band wiring group. In the patient over 50 years old, 2 (15%) in 13 cases showed excellent result of screw fixation group, while 5 (45%) in 11 cases of tension band wiring group. We concluded that tension band wiring is a better method for medial malleolar fracture to obtain early union and to prevent postoperative complications, especially in the elderly patient.

This report describes clinical cases of a palato-gingival groove on a maxillary lateral incisor with associated localized periodontal disease and pulp necrosis. The tooth of the first case was extracted because of severe bone destruction. The palato-gingival groove of the second case was eliminated using a round bur, and the resulting defect was filled with synthetic graft and covered by an absorbable membrane. Both diagnosis and treatment of palato-gingival groove were very difficult and usually extraction of the involved tooth is the treatment of choice, but combined endodontic-periodontic treatment allowed the tooth to be saved.

Inhibin is a glycoprotein usually produced by granulosa cell of ovary and is known as regulator of FSH secretion. Inhibin is consisted of two heterodimeric subunit of a, B . There are two distinct molecular forms of the B subunit that exist (BA and BB) and when combined with an a subunit, form inhibin A, and inhibin B, respectively. Ovarian reserve describes women's reproductive potential, which usually decreased according to chronological age. Because useful markers claimed for the prediction of ovarian response during controlled ovarian hyperstimulation for IVF-ET have not been always successful, new biomarker has been investigated. The purpose of this study was to observe the changes in serum and ovarian follicular inhibin A concentration during controlled ovarian hyperstimulation for IVF-ET program and to evaluate the clinical significance of inhibin A as a prognostic marker for assisted reproductive technology outcomes. From Jan 1996 to Dec 1996, 48 patients who underwent IVF-ET were included. In each patient, the Day 3 FSH, LH, E2q were measured in the first month of cycle before commencing GnRH agonist administration, In the stimulation period after pituitary down regulation, blood samples for inhibin A were collected at the day 3, day 7, day of hCG injection, day of oocytes aspiration, and day of embryo transfer. Ovarian follicular inhibin A was collected at the day of oocyte aspiration. Inhibin A concentration was measured using test kit for inhibin A (INHIBIN-EASIA (code 40.134.00), Belgium Medgenix). The changes in serum inhibin A, E2 concentration during IVF-ET program showed increasing pattern throughout controlled ovarian hyperstimulation periods. If the cut-off value of day 3 serum inhibin A determined to 0.28 U/ml, the sensitivity and specificity were 80.0%, 75.0% respectively in predicting the number of oocytes retrieved being more than five. If the cut-off value of peak serum E determined to 1316 pg/ml, the sensitivity and specificity were 89.0%, 100.0% respectively in predicting the number of oocytes retrieved being more than five. In conclusion, measurement of serum inhibin A concentration on the day of starting stimulation (day 3) could be used as a useful marker for predicting the ovarian response in IVF-ET program.
