BACKGROUND: Osteoporosis results from bone loss due to menopause [estrogen(E) deficiency] and aging. Initial skeletal effect of menopause is accelerated bone resorption with an increase in seurm calcium(Ca) and compensatory but inadequate bone formation. Secretion of parathyroid hormone(PTH) is suppressed at this time. Postmenopausal osteoporosis results in fractures predominantly of trabecular bone, i.e., vertebra. With aging, secondary hyperparathyroidism by low serum Ca and vitamin D deficiency superim poses. Senile osteoporosis produces hip fractures, area of cortical bone. The aim of this study was to- examine the association of vitamin D[25(OH)D] and intact(i) PTH with bone mineral density(BMD) after controlling for suggested confounding factors, and the possibility of low serum vitamin D and high serum iPTH concentration could impact bone loss in Korean postmenopausal women. METHODS: Data from 188 postmenopausal Korean women aged 42 to 69 were analyzed through BMD, serum 25(OH)D, iPTH, Ca, phosphorus(P), alkaline phosphatase(ALP) and clinical characteristics. Factors affecting BMD was determined by Pearson correlation and the relationship between lumbar and femoral neck BMD and vitamin D[25(OH)D] and iPTH was assessed by multiple regression analysis after adjus- ting for suggested confounding factors. RESULTS: Lumbar and femoral neck BMD, serum Ca, P were decresaed and serum iPTH was increased with aging. In Pearson`s correlation, significant contributing factors to lumbar BMD was age, height, weight, menarche, year since menopause(YSM) and ALP. And significant contributing factors to femoral neck BMD was age, height, weight, menarche, YSM and iPTH. No relationship could be demonstrated between serum vitamin D[25(OH)D] and lumbar and femoral neck BMD. How ever, after controlling for potential confounding factors, a correlation was found between vitamin D[25(OH)D] and both of lumbar (p=0.013) and femoral neck BMD(p=0.077). iPTH was inversely related to femoral neck BMD(p=0.004) only in multiple linear regression. CONCLUSION: Serum vitamin D[25(OH)D] was influencing both of vertebral and femoral neck BMD, which suggests a significant role of vitamin D deficiency in the pathogenesis of postmenopausal osteo- porosis. In age related remodeling and loss of bone, increased serum iPTH might have additive role in cortical bone of femur. These findings suggest that vitamin D is very important for optimal bone health and a deleterious effect of increased iPTH on cortical bone loss. Adequate calcium and vitamin D status have to be maintained to prevent osteoporosis in postmenopausal Korean women.

Fifty-two cases of neurilemmoma, which occurred in the skin and soft tissue and filed at the Department of Clinical Pathology, Catholic University Medical College from 1974 to 1984, were included for the clinical study. Forty four cases whose microscopic slides were available were reviewed for the histopathologic observation. The results were as follows : Clinical observations 1) The average age of the patients was 42.8% years old, and the average duration of tlie tumor was 3.9 years. 2) Eight cases were acompanied with tenderness and cases with tingling sensation. Clinica] signs described prior to biopsy were palpable mass(15), slow growing mass (8), palpable cystic mass(6) and hard mass(4). 3) The mean diameter was 2.6m (0.45cm-8cm), and the frequent sites were head and neck (32.7%), upper extremities(28.8%), lower extremities (23.11%) and trunk (15.4%) in decreasing orders. Histopathologic observations 1) 33 cases were composed of both Antoni A and type B with variable composition, but only Antoni type A was observed in 6 cases and Antoni type B in 5 Cases. 2) On the areas of Antoni type B, there were several degenerative changes including cystic change (52.3%), hemorrhage(50%), hyalinization(27.3%), necrosis(25%), and calcification(4.5%). 3) In 3 cases out of 44, the tumor was observed in the dermis and the tumors composed of Antoni A only occurred on the tongue, neck, and upper arm.

Total 11 cases of tricuspid atresia were diagnosed radiographically at Seoul National University Hospital in recent two years since 1979. Some characteristic radiological findings were analyzed in chest P-A view and cineangiographies of right atrium and left ventricle. The results are as follows; 1. Among the 11 cases, 4 cases were male and 7 cases were female. Age distribution was from 2 months to 19 years and mean age was 3 1/2 years. 2. Anatomaic types of those cases according to Keith's classification were as follows; type Ia in 2 cases, type Ib in7 cases, type Ic 1 case and type IIb in 1 case. 3. The cineangiographic features of tricuspid atresia are sequential filling of contrast media in the order of right atrium, left atrium, and left ventricle, and triangular filling defect at the base of the heart in all cases, and right atrial dimple in two cases. 4. It is essential for the diagnosis of tricuspid atresia to undertake cineangiographies of right atrium and left ventricle, and the interrelationship of great arteries.

The review of normal intravenous pyelography can give us important criteria of the diseases of the urinary system and the adjacent organs. Authors analyzed 200 cases of intravenous pyelography of normal Korean adults and measured the following points; the length of kidneys, the distance from midline to both poles, the slope degree of longitudinal axis, the ureteral length and width, the shortest distance from midline to abdominal ureters, the longest distance form midline to pelvic ureters, and configuration of urinary bladder. The results were obtained as follows; 1. The average length of kidneys in adult male was 12.53±0.78 cm on right, 12.83±0.82cm on left; in adult female, 12.08±0.72cm on right, 12.46±0.73cm on left. In the age distribution, the length gradually became shorter by getting old. In 20% of cases, right kidney was longer than left. 2. The average distance from both the renal poles to midline was longer in male compared to female. The distance from upper pole to the midline was longer in left side than right in male, but in the lower pole, there was no difference in both sexes. 3. The slope degree of the renal longitudinal axis was larger in male than in female, and lager in right kidney compared to left. 4. The length of ureter was longer on left, but there was no remarkable difference between both sexes. 5.The short set distance from midline to abdominal ureter, there was no remarkable difference between both sexes and also between right and left side. But concerning the longest distance from midline to pelvic ureter, it was longer in female; and especially in female, right side was shorter than left. 6. The longitudinal diameter of urinary bladder was longer in male, but horizontal diameter was longer in female.

Cancer pain is the most common and troublesome symptom for cancer patients. The more the cancer patient gets to the end of the life, the worse the pain. There are many clinical practice guidelines for cancer pain, and most pain can be controlled with appropriate medication by guideline. We would like to summarize various domestic and foreign clinical practice guidelines relatively simply. According to the clinical practice guidelines, medical treatment including opioids will greatly improve the quality of life of cancer patients.
