Plummer-Vinson Syndrome*

The purpose of this study was to investigate the gaps of bone-acetabular component interface, the initial mechanical stability and the effects of adjuvant screw fixation in the press-fitted two different shaped porous-coated acetabular components. Semi-hemispherical Harris-Galante II cup and full hemispherical Trilogy cup were press-fitted with or without adjuvant screw fixation in 40 bovine femur. The gaps of bone-implant interface were measured in each radiography of all specimen and axial compression tests and rotational stability tests were performed using servohydraulic tension-compression machine. There was significantly smaller gap at polar 1/3 region in the specimen implanted with Trilogy cup. But the adjuvant screw fixation did not affect the amount of gap. There was no significant statistical difference in axial load and rotational stability test in each situations of fixation. This study demonstrates that the initial mechanical stability is not influenced by the shape of semi-hemispherical Harris-Galante II cup and full hemispherical Trilogy cup and also independent of adjuvant screw fixation. But smaller gap of Trilogy cup at the polar 1/3 region indicates the possibility that less amout of wear debris of polyethylene or metal will be deposited and therefore less osteolysis or cup loosening will occur, but this hypothesis should be confirmed by the long-term clinical follow-up.

A new balloon dissector, a modification of a Foley catheter, was devised and it can be used either as a dissector or a tissue expander. Since most operating time was spent in balloon manipulation (inflation/deflation), the duct for saline injection was made to be wider than the Foley catheter. As a result, the balloon could be inflated faster than before. In order to reduce the scar at the donor site, harvest of the sural nerve using endoscopic technique is currently applied, but utilization of this method is technically difficult and requires a long operating time. For these reasons, new our method of using a balloon dissector was devised. The balloon dissector can also be used for immediate intraoperative tissue expansion for the reconstruction of small skin defects without distortion. We have found that the advantages of using the new balloon dissector include a reduction in operating time, preservation of the perforating vessels, and primary closure with less tension. In addition, this simple and inexpensive instrument is cost-beneficial to patients.

Hyperthyroidism*

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.

OBJECTIVES: Psychiatry in North Korea is believed to seem very different from psychiatry in South Korea. However, there is nearly no information regarding psychiatry in North Korea until now. Our study aimed to get information about North Korean psychiatry. METHODS: Three North Korean defectors in South Korea, whose clinical experience as medical doctors in North Korea was over 10 years, were recruited. They underwent the semi-structured interview, content of which included the clinical experience with psychiatric patients, the details of psychiatry, the treatment of psychiatric patients, the stigma of mental illness, and the suicide, in North Korea. RESULTS: In North Korea, psychiatric department was called as 49th(pronounced as Sahsip-gu-ho in Korean). Only patients with vivid psychotic symptoms came to psychiatric department. Non-psychotic depression or anxiety disorders usually were not dealt in psychiatry. The etiology of mental illness seemed to be confined to biological factors including genetic predisposition. Psychosocial or psychodynamic factors as etiology of mental illness appeared to be ignored. Psychiatry was apparently separated from political or ideological issues. The mainstay of psychiatric treatment is the inpatient admission and out-of-date therapy such as insulin coma therapy. Stigma over mental illness was common in North Korea. Suicide is considered as a betrayal to his/her nation, and has been reported to be very rare. CONCLUSION: The situation of psychiatry in North Korea is largely different from that of South Korea. Although some aspects of North Korean psychiatry are similar to psychiatry in former socialist countries, North Korean psychiatry is considered to have also its unique characteristics.
