In suicidal hanging, a death often occurs within minutes. f rescued, most victims later succumb to the respiratory failure secondary to pulmonary edema, bronchopneumonia, delayed airway obstruction, and acute respiratory distress syndrome(ARDS). Out of these, non-cardiogenic pulmonary edema is likely due to neurogenic factors or negative intrathoracic pressure. A 36-year-old female was brought to the Department of Emergency Medicine after the suicidal hanging attempt. She was unconscious but responsive to painful stimuli. A laryngeal stridor was present. The lung sound of the patient's was dear. Fourteen hours after admission, a chest X-ray showed bilateral diffuse interstitial infiltrates in both lung fields, which was compatible with ARDS. The patient was intubated and placed on a volume respirator with PEEP. She improved over the next 48 hours and a repeat chest X-ray aim showed marked clearing of the infiltrates. We report on the pathophysiologic results of this pulmonary complication and the implication of this finding, regarding the treatment of the patient.

OBJECTIVE: Although cor pulmonale due to chronic lung disease was not uncommon, there was uncertainty in its diagnosis due to the difficulty in measuring functional and anatomical changes of right heart and pulmonary vascular system. Among various non-invasive diagnostic methods presented so far, no ideal standard diagnostic criterion has been established. The authors attempted to know positive diagnostic ratio of cor pulmonale and to study the presence of the relationship between these diagnostic criteria when electrocardiographic and echocardiographic diagnostic criteria for cor pulmonale were applied to the patients with chronic lung disease. And we investigated the usefulness of echocardiogaphic diagnostic criteria for the diagnosis. METHODS: One electrocardiographic and two echocardiographic diagnostic criteria were applied to 38 patients with chronic lung disease(21 pulmonary emphysema and 17 chronic advanced pulmonary tuberculosis) for the diagnosis of cor pulmonale. Comparison was also made in their relationship. Then pulmonary artery diameter, measurement of pulmonary function test and echocardiographic examination and radio-nuclear right ventricular ejection faction were compared between the groups to ensure each criterion was satisfied. RESULTS: 1) When the three diagnostic criteria for confirming the cor pulmonale, electrocardiographic rriterion(right ventricular hypertrophy), right ventricular dimension criterion(right ventricular end-diastolic dimension>25mm, RVDd>25mm), and right ventricular wall thickness criterion (right ventricular wall thickness>6mm, RVWT>6mm) were applied to the patients, the positive rate were 32%(12/37), 30%(10/33) and 17%(6/36) respectively. A statistically significant correlation between electrocardiographic criterion and right ventricular wall thickness criterion was found to exist. 2) Various parameters of pulmonary function test and echocardiographic examination were compared in the patient groups with and without cor pulmonale when each non-invasive diagnostic criterion was applied to all patients. Followings are the results. (1) In the positive group on electrocardiographic criteria, vital capacity, forced vital capacity, and arterial oxygen tension were significantly smaller than in the negative group on electrocardiographic criterion(p<0.05), and the echocardiographic parameters of right ventricle, ie. end-diastolic area, end-systolic area, end-diastolic dimension, end-systolic dimension, mid-ventricular short axis and maximal short axis in positive group were significantly larger than in the negative group. (2) In the positive group on right ventricular diastolic dimension criterion(RVDd>25mm), percentage forced expiratory volume in 1 second and forced expiratory flow 25-75% were significantly smaller than in the negative group on right ventricular diastolic dimension criterion. (3) In the positive group on right ventricular wall thickness criterion(RVWT>6mm), vital capacity, forced vital capacity, forced expiratory volume in 1 second, forced expiratory flow 25-75% and arterial oxygen tension were significantly smaller than in the negative group on right ventricular wall thickness criterion. CONCLUSION: When several non-invasive diagnostic criteria for cor pulmonale were applied to the patients with chronic lung disease, there were some differences in its positive diagnostic ratio depending on the applied diagnostic criteria. There was also a statistically significant correlation between electrocardiographic criterion and right ventricular wall thickness criterion. When each diagnostic criterion was applied to the patients, significant differences were found in several parameters resulted from pulmonary function test and echocardiographic examination based on presence or nonpresence of cor pulmonale. But no difference in the ejection fraction measured by radio-nuclear method was shown between cor pulmonale group and non cor pulmonale group. Consequently it was suggested that applying echocardiographic criteria in addition to electrocardiographic criterion for the diagnosis of cor pulmonale in the patients with chronic lung disease is clinically useful.

Inflammatory pseudotumor of the liver is a rare benign tumor with microscopic finding of fibrous stroma and chronic inflammatory cell infiltration. Predominance of plasma cells, histiocytes, lymphocytes, some eosinophils and whorled pattern of fibrosis is often characteristic. Due to similar radiologic appearance of hepatocellular carcinoma, inflammatory pseudotumor of the liver was often misdiagnosed and hepatic resection is often performed before preoperative tissue diagnosis. We report a case of inflammatory pseudotumor, which was a 47-year-old woman with fever, upper aMominal pain and weight loss, diagnosed by sonoguided liver biopsy and treated with antibiotic therapy only without surgery. After two weeks of treatment, the radiologic image of the mass was almost disappeared with improvement of previous symptoms. This opportunity and the possible effectiveness of antibiotic treatment should keep in mind in the differential diagnosis of the hepatic mass with similar radiologic appearance of hepatocellular carcinoma.

Rectus sheath hematoma of the abdominal wall is a well-recognized, but uncommon condition, caused by a tear in an epigastric vessel and characterized by sudden onset of severe abdominal pain and palpable mass. In most cases, a precipitating cause can be demonstrated. Causes include external trauma, strenuous activities, coughing, lifting, sneezing, vomiting, straining while urinating or defecating, golfing, pregnancy and the puerperium, anticoagulation therapy, infection, chronic diesase, arteriosclerosis, hypertension, prior paracentesis or laparotomy, inadequate hemostasis or excessive retraction in surgery, and idiopathy. Unfortunately, the correct diagnosis often is missed, and the hematoma is found only during an exploratory laparotomy. Treatment should be conservative in most instances. Although the mortality rate for patients with rectus sheath hematoma is low, the condition may be fatal if the volume of the hemorrhage is large and if treatment is delayed. Hence, it should be included in the differential diagnosis of any patient who presents to the emergency department with acute onset of abdominal pain. Our purpose is to familiarlize emergency physicians with the pathophysiology, the diagnosis, and the treatment of rectus sheath hematoma. We describe a patient with fatal rectus sheath hematoma presenting to the emergency department and give a review of the literature.

BACKGROUND: Chronic exposure to ultraviolet radiation(UVE) nduces photoaging characterized by dry, deeply wrinkled, inelastic, leathery, and irregulaity pigmented skin. UVR also induces solar keratosis and carcinoma, and is a contributing factor in melanoma. Sunscreens are used to prevent solar damage to skin and, if used on a daily lass should significantly reduce the incidence of the chronie photodamaging events. OBJECTIVE: We tried to evaulate the photoaging effects of UVR in the skin and the photoprotective effect of sunscreens. METHOD: We examined the gross and microscopic changes skin of albino hairless Skh : HR-1 mice exposed chronically to ultraviolet B(UVB) and suncreen-treated mice. RESULTS: The skin of the UVB-irradiated mouse shows chear, cteristic signs of photoaging, such as deep wrinkles across the back, and thickened and a hery skin. Histologically, the photoaged skin shows increased epidermal thickness, numeross fibroblasts and inflammatory cell infiltration in the upper dermis, and many enlarged keratering cysts in the lower dermis. By the 20th week, seven of the total of 9 mice(78%) in UVB irradiated mice developed at least one tumor. Histologically, the tumor is a papilloma, but the he are many dyskeratotic cells and loss of polarity in epidermis. Octyl methoxycinnamate or TiO ZnO Talc-treated mic show a significantly decreased wrinkling score, mimmal epidermal hyperplasia, slightly increased dermal cellularity, and lack of proliferation of cysts. The octyl dimethyl PABA-treatd mice shows significantly increased wrinkling score and marked inflammatory infiltration dermis. By the 20th week, only one mouse had developed a tumor in the octyl methoxy irmamate-treated group and no evidence of tumor was seen in the TiO ZnO Talc-treated group. In the octyl dimethyl PABA-treated group, five of 7 mice(71%) developed at least one tumor. CONCLUSION: The skin which is chronically exposed to UVB is subject to photoaging and photocarcinogenesis and regular use of an adequate sunscreen would prevent these photodamaging effects of UVB.

This study was performed to investigate the factors related to tooth wear. For this study, 78 patients with temporomandibular disorders and 76 dental students without any signs and symptoms of temporomandibular disorders were selected as the patients group and as the normal group, respectively. Preferred chewing side, Angle's classification, lateral guidance pattern, head and shoulder posture wee observed clinically. Electromyographic activity of anterior temporalis and masseter muscle were recorded with BioEMG and occlusal status were recorded with T-Scan . Wear facet area of each tooth was measured from working model of upper arch corresponding to the occlusal status from T-Scan, Wear facet area were measured with planimeter in mm2. Total area were divided into incisal, canine, posterior tooth area. Anterior wearfacet area was incisor area plus canine area, and unilateral area was anterior area plus posterior area. The data collected were analyzed by SAS statistical program and the results of this study were as follows: 1. There was no significant difference between the two groups in total werafacet area, and male subjects showed tendency to have larger area in the normal group but female subjects showed tendency vice versa. 2. There was no significant difference related to preferred chewing side and Angle's classification, however, some difference was observed by lateral guidance pattern. Anterior wear facet area in subjects of canine guidance was the largest in the three subgroups. 3. Subjects with head tilting to right side had larger posterior and total area, and subjects with higher shoulder in right side had larger canine and anterior area than any other subgrous. 4. Electromyographic activity of masseter muscle was more correlated with wear facet area than anterior temporalis muscle, and tooth contact number and force were significantly correlated with wear facet area, but the most important factor affecting tooth attrition was age.
