OBJECTIVES: The purpose of this study was to analyze the incidence of indications for the removal of mini-plates over a five-year period in maxillofacial trauma patients. MATERIALS AND METHODS: The medical records of 530 patients who underwent treatment with mini-plate fixation after maxillofacial trauma were reviewed for a five-year period (May 2007 to May 2012). Patients were evaluated concerning the number of mini-plates removed, age and gender distributions, time between insertion and removal, indication for removal, and site of removal. RESULTS: The plates of 120 patients were removed (26 females and 94 males). The removal rate was 22.6%. The most frequent indication for removal was patient demand (81.7%), followed by tooth extraction (7.5%), and pain (3.3%). The most frequent removal site was the mandible (95.0%). CONCLUSION: The number of mini-plates removed was small, and the most common indication for removal was patient demand. There is no evidence to support a recommendation for the routine removal of titanium mini-plates.

Vascular malformations are the most common congenital and neonatal vascular anomalies in the head and neck region. The demand for simple and esthetic vascular malformation treatments have increased more recently. In this study, two patients that were diagnosed with venous malformations were treated with sodium tetradecyl sulfate as a sclerosing agent. Recurrence was not found one year after the surgery. This article gives a brief case report of sclerotherapy as an effective approach to treat vascular malformations in the oral cavity.

The hypokalemic periodic paralysis is characterized by intermittent falccid paralysis of extremities with spontaneous recovery. It is rarely accompanied by cardiac arrhythmia, especially fatal ventricular tachycardia or torsades de pointes. We observed a 29 year old man, who had suffered from intermittent periodic paralysis and fatal ventricular tachyarrhythmia. He had the first episode of muscle weakness in his low grade of elementary school, which lasted for 20 -30 hours. Similar episodes of muscle weakness occurred 1 -7 times per year, especially after carbohydrate rich food. On admission to emergency room, his chief complaints were generalized weakness and chest tightness, serum potassium level was 1.6mEq/l, and four extremities showed Grade 0 motor weakness. His electrocardiography(ECG) showed Atrioventricular dissociation due to sinus tachycardia and accelerated junctional rhythm, intraventricular conduction distrubance. During intravenous potassium administration, ECG showed sustained ventricular tachycardia and cardiovascular collapse occurred. So we carried out resuscitation and cardioversion. After resuscitation, he recovered from cardovascular collapse and ECG showed sinus tachycardia. But during continuous monitoring ECG showed torsades de pointes with cardiovascular collapse. We carried out resuscitation and defibrillation repeatedly. Serum potassium level was 1.7 - 1.8mEq/L at that time. After successful resuscitation, ECG showed sinus rhythm, and his mental status was fully recovered. After he admitted to intensive care unit, paralytic attack and cardiac arrhythmia did not occurred any more. Serum potassium level was maintained between 3.9 -6.1lmEq/L during his hospital days. He was fully recovered but could not take any medications(e.g. acetazolamide, potassium supplying agent and antiarrhythmic drugs) due to severe gastrointestinal disturbances. During the 30 months of postdischarge period, he experienced three mild paralysis attacks, but they were not accompanied by chest tightness, palpitation or syncope.

In this article, we critically reviewed various literatures on stress and adjustment in medical schools as a preliminary work for the future empirical study. We adopted Biopsychosocial Model as the frame of reference, which considers not only the relationship between stressor and psychological distress, but also their interaction with moderating variables such as psychosocial resources and vulnerabilities. According to the model, three important aspects of medical school stress were reviewed: 1) the types of medical school stresses, 2) the adverse effects of stressors on the adjustment such as depression, anxiety, physical symptoms, drug abuse, eating problem, attrition, change of attitude and personality, etc, 3) the moderating effects of various vulnerabilities and resources including Type A behavior pattern, masculinity/femininity, locus of control, optimism, anger expression, coping style, social support, and study skills on the suppression or development of psychological distress. Investigating the moderating variables in particular may have great clinical implications since these variables are closely related to the psychological factors concerning successful adjustment in medical school. Conclusions drawn from this review suggests several directions of future research. First, a comprehensive study which covers the whole process of medical school stress is recommended. Longitudinal design will be more suitable for dealing with the developmental features of medical education. Finally, the severity of medical school stress must be compared with the stress of general colleges and other professional graduate schools. This article is expected to provide some theoretical basis for future studies regarding the successful adjustment in the medical school, the development of preventive intervention programs and the reform of medical education systems.

OBJECTIVE: To study the clinical characteristics of pregnancy induced hypertension(PIH). METHODS: Five hundred seventy-five cases of PIH and 7,702 cases of normotensive pregnancies who were delivered their infants at Wonkwang University Hospital from January, 1994 to December, 1998 were selected for the study. The data were collected by review of the hospital record and the statistical analysis was performed using Chi-square tests, and statistical significance was defined as p<0.05. RESULTS: The incidence of PIH was 7.1% of total deliveries. Among the PIH, the incidence of mild preedampsia was found in 59%, severe preeclampsia in 36%, and edampsia in 5%. The most prevalent gestational period was 38-42wks gestation in mild PIH and 33-37wks gestation in severe PIH & eclampsia. The incidence of cesarean section was significantly higher in severe PIH & eclampsia(72.2%) than in mild PIH(48.7%) and normotensive pregnancies(39.7%). The incidence of hypoalbuminemia, preterm labor, placental abruption, disseminated intravascular coagulation, and pulmonary edema were significantly higher in severe PIH & edampsia than in mild PIH and normotensive pregnancies. Compared with normotensive pregnancies or mild PIH, severe PIH & eclampsia had significantly elevated risks for low birth weight, intrauterine growth retardation, fetal distress, low apgar score, meconium stained, and neonatal deaths. CONCLUSION: The incidence of PIH is not decreasing and it still an important role in the cause of maternal and perinatal mortality and morbidity in Korea. So, further studies are necessary to prepare a guide for the treatment of PIH.

OBJECTIVE: A subdural drain using urokinase after a burr hole hematoma evacuation was performed for subacute subdural hematoma (SASDH), and its effectiveness and safety in elderly patients were evaluated. METHODS: Between January 2013 and May 2015, subdural drains using urokinase after burr hole hematoma evacuation were performed in 19 elderly patients. The inclusion criteria were as follows: 1) a subdural hematoma occurring between 4 and 20 days after injury; 2) worsening neurological symptoms, from mild to moderate or severe, due to injury during the subacute stage; 3) a mix of solid clots (high-density lighter shadow) and fluid hematoma (low-density darker shadow) on the computed tomography (CT) scan; 4) a score of ≥9 on the Glasgow Coma Scale (GCS) assessed immediately before surgery; and 5) an age of ≥65 years. When the majority of the hematoma was evacuated on the CT, we removed the catheter. RESULTS: Under local anesthesia, a catheter was inserted into the hematoma through a burr hole. The mean age of the patients was 73.7 years (range, 65-87 years). The mean preoperative GCS score was 11.2 (range, 10-13), and the mean Glasgow Outcome Scale score for all patients was 5 at discharge. No recurrences of hematomas or surgical complications were observed. CONCLUSION: A subdural drain using urokinase after burr hole hematoma evacuation under local anesthesia is thought to be an effective and safe method of blood clot removal with low morbidity. This surgical method is less invasive for treating elderly patients with SASDH.
