Primary hyperparathyroidism is a rare endocrine disease in children. It involves bone and joint, urinary tract, gastrointestinal tract and cardiovascular system. The main cause of these involvement is high level of PTH in serum, resulting in hypercalcemia.An 11 years old male patient who had complained of limping gait since last 18 months, showed typical laboratory and radiological findings of primary hyperparathyroidism. At the ultrasonography, computed tomography and radionuclide scanning, a well defined mass(10 X 15mm) was found on the posterior aspect of the right thyroid lobe. The mass was confirmed histologically as adenoma of parathyroid gland. The patient was successfully treated with subtotal parathyroidectomy and temporal administration of calcium and vitamin D.We report this case of primary hyperparathyroidism with brief review of the literatures.

The fracture of acrylic resin dentures remains an unsolved problem. Therefore, many investigations have been performed and various approaches to strengthening acrylic resin, for example, the reinforcement of heat-cured PMMA resin using glass fibers, have been suggested over the years. The aim of the present study was to investigate the effect of short glass fibers treated with silane coupling agent on the transverse strength of heat-polymerized PMMA denture base resin. To avoid fiber bunching and achieve even fiber distribution, glass fiber bundles were mixed with PMMA powder in conventional mixer whose blade was modified to be blunt. Composite of glass fiber (11micrometer diameter, 3mm & 6mm length, silane treated) and PMMA resin was made. Transverse strength and Young's modulus were estimated. Glass fibers were incorporated with 1%, 3%, 6% and 9% by weight. Plasticity and workability of dough was evaluated. Fracture surface of specimens was investigated by SEM. The results of this study were as follows 1. 6% and 9% incorporation of 3mm glass fibers in the PMMA resin enhanced the transverse strength of the test specimens (p<0.05). 2. 6% incorporation of 6mm glass fibers in the PMMA resin increased transverse strength, but 9% incorporation of it decreased transverse strength (p<0.05). 3. When more than 3% of 3mm glass fibers and more than 6% of 6mm glass fibers were incorporated. Young's modulus increased significantly (p<0.05). 4. Workability decreased gradually as the percentage of the fibers increased. 5. Workability decreased gradually as the length of the fibers increased. 6. In SEM and LM, there was no bunching of fibers and no shortening of fibers.

The fracture of the upper end of the femur is unique in orthopedics because it is endemic to an elderly population with special problem. In trochanteric fractures open reduction and internal fixation, with a hip nail used to maintain reduction, have become the standard treatment protocol for the elderly. Unlike fractures of the femoral neck, nonunion and avascular necrosis is rare but more frequently complicated by fatal sequele, such as pneumonia, thromboembolic disease, and decubitus ulceration. In order to achieve early ambulation of a patient with a trochanteric hip fracture, two conditions must be met: The implant used for fixation must be strong enough to withstand loadings exerted upon it during fracture healing, and the fracture itself must be rendered stable in a suitably reduced position. The treatment of the fracture of the femoral neck has a long and frustrating history. As recently as 20 years ago McCarroll remarked that this fracture must be considered “unsolved” until the incidence of aseptic necrosis and nonunion could be diminished or abolished. But now with adequate reduction, impaction, accurate internal fixation with newer devices, and carefully supervised postoperative care the fracture of the femoral neck can be expected to heal at least 90 per cent of the patients. A lower incidence of recognizable aseptic necrosis has been reported under these circumstances. X-ray films of 94 cases of hip nailing for hip fractures were collected in the Department of Orthopedic Surgery of Seoul National University Hospital. Twenty seven cases considered to be failed in hip nailing were analysed radiologically, and following results were obtained. 1. The incidence of failed hip nailing was most frequent in the fifties with average age of 54. 6 years, which seemed somewhat younger than that of the hip fracture. There was no sexual difference. 2. Hip nailings were failed in 23 cases of the femoral neck fractures and in 4 cases of the trochanteric fractures, which revealed respectively 52.3% and 8.2% of failure. Among these the technical failure was 22.7% in femoral neck fractures and 6.1% in trochanteric fractures. 3. Among the various fixation devices, Smith-Petersen nail or hip screws which has no side plate to fix the shaft rigidly showed high failure rates. 4. In all cases the etiology of the failed hip nailing was functional, such as failure of reduction, failure of fixation, penetration of the head, avaseular necrosis, infection, and inadequate postoperative management. 5. Most cases of femoral neck fractures which was not achieved near anatomical reduction was failed in fixation. 6. Too long or short nails showed high failure rates. In view point of this, hip nail should fix the lateral cortex, calcar femorale and center of subchondral bone, even in the trochanteric fracture. So devices such as heavy compression sliding nail or multiple pinning were more desirable to achieve complete fixation. 7. When, in the fresh fractures of the femur neck cannot be reduced to an anatomical or slightly overcorrected position, endoprosthesis should be considered seriously. When the joint is abnormal, the total hip arthroplasty can reduce morbidity and mortality, and also shorten the hospitalization.

BACKGROUND: Substrates play an important role in the effectiveness of the indirect immunofluro-rescence test. The monkey eaophagus has been known to be a more reliable and reproducible substrate than any other animal substrates for detecting pemphigus vulgaris autoantibodies, but it is quite difficult to get the monkey esophagus in Korea, therefore, we tried to find other substrates which could be substituted for it. OBJECTIVE: We studied to select the substrate which can be the most sensitive, to compare the immunofluorescent sensitivity of various animal substrates and fores,cins for detection of pemphigus autoantibodies, and finally to evaluate the effectiveness of cultured hunan keratinocytes as a substrate for indirect immunofluorescerice. METHOD: With foreskin, guinea pigs, cats, rats, dogs, rabbits and cultured human keratinocytes as substrates, an indirect imrnunofluorescence test was performed to detect pemphigus vulgaris autoantibodies in seven sera from the active patients before treatment and diluted serially from 1:10 to 1:1280 RESULT: We could detect pernphigus autoantibodies in all animal subtrates used in this study except rats and obtain good immunofluorescent results with foreskin, guinea pigs, and cultured human keratinocytes. The results were moderate with dogs, cats, rabbits, and poor with rats. CONCLUSION: We confirm thut cultured human keratinocytes can be a good effective substrate. According to effectiveness, subtrates can be divided into three groups. Foreskin, guinea pigs, and cultured human keratinocytes are included in the good effective substrate group, dogs, cats, and rabbits in the modeate group and rats in the poor substrate group, but we can not find any superiority of substrates within each groups.
