Most orthopedic surgeons were aimed at the rigid internal fixation on the surgical treatment of the fracture. And the compression plate was developed and regarded as an excellent rigid internal fixation device by its advantages of accurate anatomical reduction, early joint mobilization and shortening of the duration of the fracture healing, which are chief aim of A.S.I.F. method. During the period of January 1970 to December 1979, 67 cases of diaphyseal fractures of the long bones were treated with compression plate according to A.S.I.F. method at the Department of Orthopedic Surgery, College of Medicine, Seoul National University and results were obtained as follows: 1. The age of patient was ranged from 15 to 77, and the highest incidence was in the 3rd decade male group (31.4%). 2. Old fracture cases were slightly more than fresh cases, and the fresh femur fracture was the commonest. 3. The periods of the postop immobilization of fresh fractures were 3.7 weeks in humerun fracture, 6.3 weeks in forearm fractures, 8.7 weeks in femur fracture and 7.0 week in tibia fracture, and in old fractures about 4 weeks was longer than fresh fractures. 4. The bony union was accomplished in all cases between 8 week and 24 week. 5. The complication were 4 superficial infections, 4 deep infections, 1 delayed union and 9 joint stiffnesses. 6. Compression plate fixation is considered as an excellent method for the treatment of the fractures of the long bones.

BACKGROUND: Intermediate myasthenia syndrome(IMS) is thought to have clinical importance because it may cause sudden respiratory failure during the recovery phase of a cholinergic crisis of organophosphate poisoning. We designed this study to identify the prevalence, the inducing agent, clinical predictor, and the proposed treatment of IMS. METHODS: Patients who had admitted with the diagnosis of acute organophosphate poisoning from 1992 to 1998 at two teaching hospitals were enrolled in this study. We selected the cases of IMS based on a review of medical records using modified He's criteria. RESULTS: Twelve(12) out of 110 patients with acute organophosphate poisoning were diagnosed for a prevalence at 10.9%. The drug inducing IMS were identified as dichlorvos, fenthion, EPN, methidathion, and phosphamidon. The occurrence of IMS was not related to either the initial treatment with atropine and pralidoxime, or the level of serum cholinesterase. Complications were pneumonia, sepsis, pancreatitis, and pseudomembranous colitis, etc. Eleven(11) patients were discharged without sequelae, and one patient was discharged as a hopeless care. CONCLUSION: This study suggests that IMS is not rare, so close observation is required to detect IMS in organophosphate-poisoning patients. Also, more studies are required to find predictors and treatments.

PURPOSE: The aim for this study was to investigate clinical manifestation of seasonal influenza A and B during the 2012 winter season in Wonju, South Korea. Their clinical and laboratorial characteristics and effect of oseltamivir were compared and analyzed. METHODS: Children under the age of 18 years who visited the Wonju Severance Christian Hospital with fever or acute respiratory symptoms and who were diagnosed with influenza A or B by rapid antigen test from nasopharyngeal swab were selected for the study. The medical records of patients were retrospectively reviewed. RESULTS: Influenza A was detected in 374 patients (83.7%), and influenza B in 72 (16.6%). The incidence of influenza A was highest in February (n=186), while that of influenza B was highest in March (n=36). The most common symptoms were fever (n=434, 97.1%) and cough (n=362, 81.0%). No significant differences were observed between influenza A and B in symptoms and laboratory data. Patients who had used oseltamivir within 2 days showed statistically lower admission rate, shorter admission duration, and lower incidence of pneumonia. CONCLUSION: This study found no statistical difference between influenza A and B, in symptoms, progression, and laboratory test, but those who were treated with oseltamivir given within 2 days of the onset of fever experienced more positive outcomes.

BACKGROUND: Hemorrhage itself has been shown to produce abnormalities in immunity, particularly depression of the lymphocyte function. In order to better examine the amount of hemorrhage required to suppress the lymphocyte function, we determined the effect of graded fixed-volume hemorrhage on splenocyte proliferation and the lymphocyte subpopulation. METHODS: Male Sprague-Dawley rats(weight, 350~400g) were anesthetized, subjected to hemorrhages of 7.5ml/kg, 15ml/kg, and 22.5ml/kg by percutaneous cardiac puncture with 26G needles. After 1, 2, 4, and 7 days, animals were killed to obtain the blood and spleen. The splenocyte proliferative capacity was measured by using the tritiated thymidine incorporation technique, and the peripheral lymphocyte subpopulation was determined using flow cytometry with the following monoclonal antibodies: T cell(CD3+), T helper cell(CD4+), T cytotoxic cell(CD8+), and B cell(CD45RA+). RESULTS: Hemorrhage of 7.5ml/kg did not induce depression of splenocyte proliferation. However, for hemorrhage greater than 15ml/kg, the splenocyte proliferative capacity was significantly depressed at 2 days after hemorrhage and recovered at 4 days. Hemorrhage induced no changes in the relative percentage of lymphocyte subpopulations and in the number of each cell in peripheral blood. CONCLUSION: This study suggests that cellular immunity is depressed at 48 hrs after a hemorrhage greater than 15ml/kg without any change in the peripheral lymphocyte subpopulation.

PURPOSE: We assessed the feasibility and efficacy of a laparoscopic approach in surgically managing various conditions of the acute abdomen. METHODS: This report presents preliminary data from our ongoing prospective study. Sixty patients underwent a diagnostic or a therapeutic laparoscopy for acute or subacute abdominal conditions between July 1997 and September 1998. RESULTS: Conditions were classified into trauma (n=8), peritonitis (n=41), and obstruction (n=11). Trauma included 5 blunt (2 small bowel perforations, 1 spleen rupture, 2 mesenteric ruptures) and 3 stab injuries. Peritonitis included 23 duodenal ulcer perforations, 10 acute cholecytitis/empyema, 3 colon perforations, 1 tuberculous peritonitis, 1 ectopic pregnancy, 1 ruptured corpus luteum, 1 appendicitis, and 1 ruptured liver abscess. Obstruction included 5 intussusceptions (4 Children, 1 adult), 2 intestinal adhesions; and 4 congenital hypertropic pyloric stenoses. Among the 54 cases of therapeutic laparoscopy, 9 cases were converted during the procedure (conversion rate: 16.7%). There were 2 intraoperative (bowel perforation) and 4 postoperative (1 subphrenic abscess, 1 incomplete adhesiolysis, 1 port site hernia, 1 port-site seroma) complications. CONCLUSION: Our preliminary data may justify further clinical study to clarify the role of laparoscopy in managing acute or subacute abdominal conditions.

As regard to the treatment modality and its prognosis following the treatment, there are some differences between the thoracolumbar compression fracture and bursting fracture. If bursting fracture is accompanied by nerve injury, especially if the fracture fragment is compressing the spinal cord, it is reported that decompression with early surgical intervention would achieve a much better prognosis. Therefore, the authors tried to suggest an overall statistics on the patient's age, mechanism of injury and injured site and to compare the sensitivity of tools used in diagnosing bursting fracture radiologically, as well as the sensitivity of posterior vertebral body angle, which is used in diagnosing subtle bursting fracture. Three hundred forty three patients admitted to emergency center of Yongdong Severance Hospital with a thoracolumbar fracture from 1992. Jan. to 1994. Dec. Of the 343 patients, minor fracture and those with insufficient X-ray films and clinical notes were excluded from the study. The study was done with 199 patients in retrospective method. All the 199 patients had plain X-ray and computed tomography taken. the results were as follows 1. The male to female ratio was 114 to 85 with average age being 47.1 years old(14-93 years old). 2. The mechanisms of injury were falling down, traffic accident, slipped down, sprain and confusional injury in the order written. 3. There were 67 cases of compression fracture and 132 cases of bursting fracture. 157 cases had I level injury in the order of Ll, T12, and L2, 33 cases had 2 level injury, and 8 cases were injured in 3 level of the spine. 4. Of the factors determining the radiological diagnosis of bursting fracture, the disruption of posterior cortical line had the highest sensitivity. 5. Of the 45 cases of 1 level injured subtle bursting fracture, those with posterior vertebral body angle of more than 100 degree radiographically had a sensitivity of 82%. Of the thoracolumbar fractured patient admitted to the emergency room, searching for disruption of posterior cortical line in plain film helped in diagnosing bursting fracture, and calculating the posterior vertebral body angle helped in determining whether further computed topography was needed in subtle bursting fracture.

In Korea, there are about 8 million motor vehicles and one-fourth of it is motorcycle. Last year Korean government report on the motor vehicle accidents claimed 12,781 cases of motorcycle accidents and it account for 5.1% of all of motor vehicle accidents occurred in Korea. But this is too broad analysis and lack of statical values. In general, most of people think motorcycle rider will suffer or die from head injuries sustained with motorcycle accident. Even though mandatory law on wearing helmet during motorcycle ride, but we see too many motorcycle riders not wearing helmet, especially in teenagers. The loss of young person by accident is great loss for family, society and economy of nation. No one will doubt the effectiveness of helmet on reduced incidence of head injuries. And multiple studies from United States of America have clearly demonstrated the benefit of helmets in motorcycle accidents. The following study was undertaken to determine the relationship between head injuries and helmet use in motorcycle accident, as well as analysis of general motorcycle accident.
