BACKGROUND: The purpose of our study was to evaluate the accuracy of reduction based on postoperative computed tomography (CT) images after arthroscopic stabilization using tightrope system for unstable distal clavicle fracture. METHODS: Twelve patients with distal clavicle fracture combined with coracoclavicular (CC) ligament injury (type II, V) who received arthroscopically assisted fixation using a flip button device were evaluated for accuracy of reduction using 3-dimensional postoperative CT scan by measuring the degree of distal clavicular angulation and clavicular shortening. RESULTS: Immediate postoperative plain radiograph confirmed restoration of the CC distance (CCD) in 10 patients. At final follow-up, the CCD remained reduced anatomically on plain radiographs in these patients. All patients showed excessive posterior angulation and shortening compared to the opposite side. The average Constant score recovered to 94.8 at final follow-up. CONCLUSIONS: Indirect reduction and arthroscopic subacromial approach with flip button fixation of unstable distal clavicle fractures demonstrated favorable clinical results despite unavoidable posterior angulation of distal clavicle and shortening the total length of clavicle.

PURPOSE: Painful plantar callosities under the second, third or fourth metatarsal head have been controverted about its treatment mordalities. We performed the vertical chevron osteotomy in patients with painful callosities on the second and third metatarsal head, and evaluated the outcome clinically. MATERIALS AND METHODS: Fourteen cases from 10 patients who had plantar keratosis were operated by vertical chevron osteotomy from March 2005 to October 2008. We used K-wire fixation for all cases. We evaluated the clinical results by the patients' satisfaction and disappearance of plantar lesion. RESULTS: The plantar keratosis was completely disappeared in 8 cases and partially in 5 cases. In 2 cases, patients expresses their pain caused by constant metatarsalgia that was suspected to be dorsal incisional pain and joint capsulitis. Transmetatarsalgia was not appeared. CONCLUSION: We consider vertical chevron osteotomy as a good surgical method for treatment of plantar keratosis.

A fixed drug eruption is a cutaneous reaction caused by various drugs, which include phenazone derivatives, barbiturates, sulfonamides, tetracyclines and phenolphthaleins. An eruption caused by piroxicam is very rare and there have been no previous reports in Korea. A 49-year-old woman was seen with mutiple erythematous patches and some bullae that appeared after oral administration of piroxicam. The patient had had two similar episodes after oral administration of piroxicam. We performed patch test with piroxicam and could confirm a fixed drug eruption caused by this durg.

Adult intussusception is rare involving of only 1% of the causes of bowel obstruction. We report a case of a 39-year-old female with intussusceptions due to inverted Meckel's diverticulum. She visited our hospital for diffuse abdominal pain during 1 week and aggravated abdominal pain for 2 days. Vital signs were stable, and there was periumbilical tenderness. She had no history of abdominal operation. CT scan showed a 3.7x2.1 cm of fatty mass with focal intussusception in the distal ileum. When the emergency operation was performed, the patient was found to be suffering from ileocolic intussusception. A manual reduction of intussusception showed inverted Meckel's deverticulum at 65 cm proximal to the ileocecal valve, and the segmental resection of small bowel including a Meckel's diverticulum was performed. Pathologic examination revealed a Meckel's diverticulum containing a 0.6x0.6 cm sized aberrant pancreas.

Retroperitoneal fibrosis (RPF) is a rare disease characterized by marked fibro-inflammatory tissue in the retroperitoneum. Approximately 70% of cases of RPF are idiopathic, while the rest can be secondary to several other causes. The diagnosis is mainly obtained by imaging modalities such as computed tomography (CT). However, histological examination should be considered when the clinical manifestations and imaging studies suggest malignancy. In particular, in malignant diseases with retroperitoneal metastases, abnormal collagen plaques are formed from an exuberant desmoplastic response, which may not be distinguishable from RPF on CT scans. Therefore, even if CT suggests RPF, biopsy is essential to identify malignant disease because it typically results in a fatal prognosis. Here, we report a case of metastatic adenocarcinoma of unknown primary site that developed only in the retroperitoneum and was initially diagnosed as RPF based on CT findings.

Background/Aims: This study was conducted to identify prognostic factors in patients with papillary thyroid cancer (PTC) at the time of first radioactive iodine (RAI) therapy, and to evaluate the clinical value of the thyroglobulin (Tg) increase after RAI. Methods: Serum Tg was sampled prior to (pre-Tg) and 7 days after RAI (post-Tg) in 680 patients with PTC. Patients were classified into excellent response (ER), biochemical incomplete response (BCIR), structural incomplete response (SIR), and indeterminate response (IR) groups using dynamic risk stratification at 6 to 18 months after RAI therapy. Results: After RAI therapy, 514 patients (75.6%) had an ER, 34 (5.0%) had a BCIR, 13 (2.0%) had an SIR, and 119 (17.5%) had an IR. Pre-Tg level was significantly different among the groups, with the highest level being in the SIR group, followed by the BCIR, IR, and ER groups. However, post-Tg levels were not different among the groups. Post-Tg level increased significantly after RAI therapy compared to the pre-Tg level (mean 13.8 ± 32.2 ng/mL vs. 2.5 ± 8.9 ng/mL). In 422 patients whose pre-Tg level was < 1 ng/mL, 205 had post-Tg levels < 1 ng/mL, while 167 had post-Tg levels of 1 to 10 ng/mL, and 50 had levels > 10 ng/mL. No difference was observed in the response to therapy. Differences in RAI dose and uptake pattern were observed among the three groups. Conclusions Pre-Tg was useful as a prognostic factor in patients with PTC. In patients with low pre-Tg, increased post-Tg may reflect remnant tissue and does not help predict the prognosis.

BACKGROUND: Propofol has a high incidence of pain when administered by intravenous injection. Among the many different methods available, lidocaine is used most frequently to minimize this pain. Propofol also has a depressant action on hemodynamics, especially in the elderly. The present study was aimed to examine whether lidocaine affects hemodynamic changes associated with propofol injection and endotracheal intubation, and whether it attenuates propofol-induced pain. METHODS: Eighty patients, over 60 years old, ASA physical status I and II, were randomly divided into four groups of 20 each according to lidocaine dosage mixed with 2 mg/kg of propofol given over 30 seconds during the induction of anesthesia; 0 mg (control group), 20 mg, 40 mg and 80 mg. Mean arterial blood pressure (MAP), heart rate (HR), and bispectral index scale (BIS) were measured before anesthetic induction (baseline value), 1 minute after the start of induction, immediately before endotracheal intubation, and then every minute for 5 minutes. Injection pain was scored as none, mild, moderate, or severe. RESULTS: MAP decreased significantly following the propofol injection and then increased after endotracheal intubation in all four groups, the magnitude of this decrease did not differ among the groups. HR increased after the propofol injection and then decreased. It increased again after intubation in all four groups. BIS was decreased by the induction of anesthesia, but was not affected by endotracheal intubation in any group. The three lidocaine groups had a lower incidence and severity of propofol-induced pain than the control group, and the effect were comparable among the lidocaine-treated groups. CONCLUSIONS: Our results indicate that lidocaine 20, 40 or 80 mg mixed with propofol does not affect the hemodynamic changes associated with propofol and endotracheal intubation, but that they similarly attenuate the injection pain associated with propofol.

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.
