Diaphyseal fractures of the radius and ulna present high incidence of malunion and non-union because of difficulty in reduction and maintenance of two mobile, parallel bones in the presence of the pronating and supinating muscles which exert angulatory as well as rotational forces. Over the years various methods of open reduction and internal fixation or the closed method have been advocated, but open reduction, especially fixation with compression plate and screws resulted in more satisfactory results was proved recently by the major clinical reports. From March. 1977 to December. 1985, 59 cases of diaphysesl fractures of the forearm both bone in adult and children were managed in the Department of Orthopedic Surgery, Chonbuk National University Hospital and comparisions have been made between the conservative treatment group and operative group. The obtained results were as follows; 1. The most common csuse of injury was fallen on the outstretched hand in children and traffic accident in adult. 2. The most frequent site of the fracture was middle one-third(50.8%). 3. The most common pattern of the fracture was stable fracture(50.1%). 4. The applied methods for management of the fractures include cast immobilization after manual reduction or skeletal traction, K-wire fixation, compression plate and screws, intramedullary nailing, and combined. 5. Comparision of conservative treated group with operative treated group was as follows. 1) In roentgenologically, excluding those complicated by nonunion or infection, average bone union time of conservative group in children and adolescence was 10.2 weeks and in adult was 16.7 weeks, and of operative group was 13.9 weeks. 2) According to Grace and Eversmann's evaluation, Satisfactory results were shown in 80.0% of children and adolescence group treated by conservative method and 86.7% of adult group trested by compression plate and screws. 3) Among the various internal fixstion methods, compression plate and screws method was the best measure for rapid bone union and functional recovery in adult. 4) Any marked difference between each group was not seen in nonunion, but angulstory and rotational deformity were more common in conservative group and infection was developed 2 cases in operative group only. 6. There was no noticesble difference between each treatment in children and adolescence, but operative treatment, especially compression plate and screws, in adult was more superior to conservative treatment with. regard to bone union time and functional result.

OBJECTIVES: Over the last 30 years, despite the increasing sophistication in medical care, the mortality of acute renal failure(ARF) has remained virtually unchanged at 40-50%, but the reasons remain unknown. This study intend to identify prognostic risk factors influencing survival and predict the mortality in ARF patients. METHODS: We retrospectively analyzed 152 patients with ARF who required renal replacement therapy, or whose serum creatinine level above 5 mg/dl, from Jan. 1988 to May. 1995. Multiple factors which may influence mortality were evaluated by univariate and multivariate analysis. RESULTS: 1) Of the 152 patients, 97 were male and 55 were female. The mean age was 47 years and the overall mortality was 36.8%. 2) Based on the univariate analysis, age>60 years, cause of ARF, APACHE II score, number of failing organs, peak serum creatinine level, PaO2, coma, hypotension, ARDS, GI bleeding, ventilatory support, need for antiarrhythmics, DIC, cardiovascular failure, pulmonary failure, neurological failure, and gastrointestinal failure were all significant factors discriminating between survivors and nonsurvivors(p<0.05) 3) By multivariate analysis, hypotension, coma, ventilatory support, and age over 60 years were significant independent predictors influencing survival in ARF patients and logistic equation and logit score were as follows : z=-2.04+1.32(age over 60)+2.18(hypotension)+2.88 (ventilatory support) + 3.28(coma) P=ez/(1+ ez) 4) In ROC(receiver-operating characteristic)curve, when the cutoff point was 0.2, maximum sensitivity was 75% and maximum specificity was 82%. CONCLUSION: In ARF, prognostic risk factors for mortality were age over 60 years, hypotension, assisted ventilation and coma. The logit score by multiple analysis is a reliable predictor of mortality in ARF patients, however the further studies are required to confirm these results.

Primary malignant lymphoma of the appendix is an unconnnon neoplasm although the gastrointestinal tract is the most common extranodal site of malignant lymphoma. We report a case of primary malignant lymphoma of the appendix in a 54-year-old male, who presented with pain in the right lower abdomen. An appendectomy was performed. The appendix measured 9.5 cm in length and 5.5 cm in diameter. Cut sections showed a solitary circumferential mass in the appendiceal lumen. Light microscopic features were compatible with malignant lymphoma of diffuse large cell type(Working Formulation) and the immunophenotype was B cell type.

BACKGROUND: Pulmonary thromboembolism is relatively frequent and potentially fatal. However, it is commonly misdiagnosed. The incidence of pulmonary thromboembolism is not decreasing despite advances in diagnosis and effective prophylatic measures. Its potential for significant sequela necessitates a prompt diagnosis and treatment. Unfortunately, there are many difficulties and problems regarding accurate diagnosis. There is a low prevalence of deep vein thrombosis and pulmonary thromboembolism in Korea and only few reports on this subject are available. METHOD: The clinical features of 36 patients, who were diagnosed with pulmonary thromboembolism at the Korea University medical center, were reviewed. RESULTS: 1) There was no significant difference in prevalence between men an women, and the mean age was 50.9 years in men 59.2 years in women. 2) The frequent causes of pulmonary thromboembolism were malignancies (22.2%), surgery (22.2%), and heart disease(8.2%). Specific causes were not identified in 33.3%. 3) The most common symptom was dyspnea(72.2%), and the most common sign was tachypnea(61.1%). 4) The EKG findings were normal in 28.6%, and S1Q3T3 pulmonale pattern in 25.7%, ST or QRS changes in others. 5) The chest X-ray findings indicated pulmonary infiltation in 37.5%, cardiomegaly in 15.6%, pleural effusion in 12.5%, and normal in 27.8%. The perfusion lung scan showed a high probability in 66.7%, and intermediate or low probability in 33.3%. 6) The pulmonary arterial pressure(PAP) in the high probability groups was 57.9mmHg with a higher mortality rate(35%). CONCLUSION: Pulmonary thromboembolism is not uncommon in Korea and its clinical features do not differ greatly from those reported in the literature. When pulmonary thromboemblism of unknown causes are diagnosed, a search for an occult malignancy is recommended. Rapid diagnosis and treatment are achieved when thromboemblism is suspected.

The mineral content and width of bone can be determined noninvasively by “bone densitometer”, which measures the absorption by bone of a monoenergetic photon beam that originates in a radioactive source(Iodine-125 at 27.3 Kev). The intensity of the beam transmitted by the bone is measured by a scintillation detector. The bone mineral density is obtained from dividing the bone mineral content by bone width. Since Cameron and Sorenson, in 1963, first described the photon absorptiometry, many investigators have studied this method and applied it clinically. In order to determine the bone density of normal koreans, and compare it with that of fracture risk group, we measured the bone density of the distal one third of the nondominant radius in 152 normal persons(55 male, 97 female), and 54 patients(23 male, 31 female) having the risk of spontaneous fracture from the third to seventh decades. This data were also compared with those of normal Caucasians. The results were as follows. 1. The average bone densities(gm/cm2) of normal men from the third to the seventh decades were 0.773 ±0.055, 0.749 ±0.070, 0.770 ±0.060, 0.797 ±0.053, 0.664 ±0.126, respectively and those of normal women were 0.680 ±0.058, 0.680 ±0.036, 0.674 ±0.052, 0.608 ±0.084, 0.523 ±0.093, respectively. 2. The average bone densitied(gm/cm2) of fracture risk men from the third to seventh decades were 0.647 ±0.072, 0.719 ±0.050, 0.729 ±0.085, 0.699 ±0.064, 0.562 ±0.049, respectively and those of fracture risk women were 0.603 ±0.049, 0.061 ±0.021, 0.326 ±0.034, 0.494 ±0.045, 0.430 ±0.035, respectively. 3. There were statistically significantly differences in the bone densities between the normal population group and the fracture risk group. 4. The average bone densities(gm/cm2) of normal koreans were lower than those of normal Caucasians by 0.115 ±0.023 in male, and 0.091 ±0.005 in female. 5. We belive that bone densitometer is an effective tool in early detection and treatment in metabolic bone deseass including osteoporosis.

Isoimmune hemolytic disease of the newborn due to anti-E is a disease characterized by the progressive neonatal hyperbilimbinemia and anemia which is caused by the IgG antibody transmitted from the mother to the ferns. Authors have experienced two cases of isoimmune hemolytic disease due to anti-E, who presented with jaundice on the first and the second day of life, respectively. The ABO and Rh blood types of their mother and father were B, CcDee and O, ccDEE, respectively. Both babies showed positive direct Coombs test and the mother showed strong positive indirect Coombs test. Antibody identification tests were made only in the first case and the mother, both of which revealed anti-E antibody. The first case was treated with phototherapy for 3 days and two blood transfusions. The second case was treated with phototherapy for 6 days and two exchange transfusions.

Sarcoidosis is a multisystem granulomatous disorder of unknown etiology. The authors experienced a case of sarcoidosis in 22-year-old female who had palpable mass on left eyelid. Ocular examination revealed enlargement of lacrimal gland, anterior uveitis, iris nodule and abnormal fundus findings such as hyperemic disc with blurred margin, perivasculitis, vitreous himorrhage, and choroidal nodule. Systemic investigation yielded bilateral hilar lymphadenopathy and pulmonary infiltration, enlargement of multiple supraclavicular lymphnodes. Histologic findings of lacrimal gland revealed non-caseating epitheloid granuloma. In the course of corticosteroid therpy, above signs are subsided gradually, but exacerbated when she discontinued steroid because of the development of acne on the face. And so, we confirmed the sarcoidosis.

Succinylcholine-induced prolonged neuromuscular blockade may occur in patients with either a low level of plasma cholinesterase activity or genotypically abnormal form of that enzyme. We experienced a case of succinylcholine-induced prolonged apnea due to a low level of plasma cholinesterase activity. A 31-year-old woman, full term primigravida, underwent cesarean section for breech presentation under general anesthesia. Familial and past medical history were nonspecific and preoperative physical and laboratory findings were within normal range. After operation, delayed apnea was detected and lasted for about one hour. We performed controlled and assisted ventilation for two and half hours. Plasma cholinesterase activity measured 30.00 IU/L (colorimetric method, normal value: 1130~1960 IU/L) at the first postoperative day. She was discharged on 7th postoperative day without any sequelae. From follow-up study after six months, it measured 1.02 U/ml (EIA, normal value: 7~9 U/ml).
