The structures forming the shoulder joint are very complex and the biomechanical effects of them on the joint are not clearly lunderstood. Frequently the long head of the biceps brachii muscle is dislocated naturally and it has been said that the supratubercular ridge, the depth, and angle of medial wall of the intertubercular groove are important. And the angles between the long axis of the humerus and the axis of head and neck are important clinically. So the authors studied them in the 105 specimens of the Korean adults humerus. The results are as follows: 1. The complete type of the supratubercular ridge was present in 22.9% and the partial type was in 53.3% 2. If the ridge was present, the spur of the lesser tubercle was present in 67.5% and if not present, the spur was in 8%. 3. The angle of medial wall of the intertubercular groove was variable, and the angle less than 45 was 13.41°. 4. The angles between the long axis of the humerus and the axis of head and neck were much greater in male than female (P<0.05). 5. The average diameter of the head of the humerus was 4.42±0.4cm in male and 4.4±0.4cm in female (P < 0.05).

Treatment modalities for herniated lumbar intervertebral disc are the conservative method, chemonucleolysis, percutaneous diskectomy and operation. Conservative treatment is effective in 70–80% of the acute stage and the other 20% requires chemonucleolysis, percutaneous diskectomy or operation. Indications for operation are cases not improved after conservative treatment, recurrent cases and cauda equina syndrome. Mixter and Barr(1934) demonstrated that laminectomy and surgical removal of disc material could relieve symptoms, but spinal segmental instability, incomplete removal of the disc and postoperative adhesion of the nerve root caused low back pain after long-term follow up. Thus, the authors evaluated the plain X-ray and computed tomographic findings in 21 cases of failed laminectomy to determine the cause of failure. The results were as follows ; 1. Among 21 cases, 18 cases complained of low back pain with sciatica and 3 cases complained of low back pain. 2. In all cases, disc space narrowing was detected on plain X-ray. Total laminectomy and diskectomy promote insufficiency and instability of the lumbar and lumbosacral spine. Whenever one attempts to do total laminectomy and diskectomy, it is recommended that spine fusion be performed in same operating field. 3. Several findings were detected on CT scan : 8 disc protrusions in the operation site, 6 disc protrusions in the operation site and spinal stenosis, 4 extradural scars, 1 extradural scar and other site disc protrusion and 2 cases of spinal stenosis and spondyloisthesis. 4. Computed tomography in cases of failed laminectomy offers more information than has been available by any other imaging method.

BACKGROUND: Automated external defibrillator(AED) represent a major breakdown to permit more widespread application of the principle of early defibrillation. Many recent efforts to improve emergency medical services(EMS) and increase survival rates are simply efforts to get defibrillation to patients as rapidly as possible. AED is major innovation for the prehospital care of ventricular fibrillation cardiac arrest patients. The purpose of this study is to evaluate the course of initial training to three different groups(nurses, firefighters, and EMT trainee) to use AED. METHOD: We studies the efficacy of education of AED to 33 nurses, 15 EMT trainee, and 16 firefighters. Training lasted 75 mins and included 45 mins an overview of defibrillation, protocols for using the AED, and operation of the AED(Laerdal Heartstart 3000),15 mins demonstraion.4 check list was used to grade the performance of cardiopulmonary resuscitation, operation of the AED, and the time required to deliver the first three defibrillations. RESULT: There were no statistically significant differences in performance and time required to deliver an electrical countershock among the groups(p=0.4). To the second test 92fo of all group completed all steps successfully. The step most often foiled was the preparing of the AED for defibrillation. CONCLUSION: In nurses, EMT trainee, and firefighters, it is both feasible and effective to train AED use irrespective of the degree of the trainee.

We report a case of disseminated cutaneous metastatic carcinoma from stomach carcinoma in a 66-year-old male who complained chiefly of widespread cutaneous nodules. He had been admitted to the Department of Internal Medicine for stomach carcinoma. A radiological examination revealed a diffuse stomach wall thickening from the fundus to the antrum, and enlargement of paraaortic and pericaval lymph nodes during an abodominal CT scan. The clinical findings manifested above may suggest cutaneous metastasis from stomach carcinoma. A histological examination of the skin and stomach biopsies showed atypical cells with pleomorphic, hyperchromatic nuclei and bubble-like cytoplasm, which are consistent with poorly differentiated adenocarcinoma. Immunohistochemical stainings showed that these cells were positive for epithelial membrane antigen (EMA), carcinoembryonic antigen (CEA) and low molecular weight cytokeratin.

PURPOSE: The purposes of this study were to explain the phenomena of hot flashes in climacteric women by using Mexameter, Skin Thermometer, Corneometer, and Laser Doppler Perfusion Imager (LDPI) objectively and to identify the interrelation between the subjective and objective measurements of hot flashes by comparing the two as reported in retrospective questionnaires. METHODS: The participants were one hundred women (45-60 yr) who were not currently on hormone therapy, and had reached hot flash scores of 10 or higher. Hot flashes were measured in a temperature and humidity controlled room for 7 hr from 10 am to 5 pm. Hot flashes were measured subjectively and recorded via the Hot Flash Diary Report. When participants felt the hot flashes, they were measured objectively by Mexameter, Skin Thermometer, Corneometer, and LDPI. RESULTS: The frequency of hot flashes in participants ranged from 1 to 7 times. When hot flashes occurred in participants, the erythema, skin temperature, skin hydration, and blood perfusion showed statistically significant changes in all measurements. But, the subjective and objective measurements of hot flashes showed only weak correlations. CONCLUSION: Results indicate a need for future research with subjective and objective measuring instruments chosen depending variations identified for the study.
