BACKGROUND: The purpose of this study was to identify the clinical and radiological outcomes of hook plate fixation for lateral end fracture of the clavicle and acromioclavicular dislocation. METHODS: There were a total of 20 cases with lateral end fracture of the clavicle and 16 cases with acromioclavicular dislocation. All patients were evaluated for range of motion, functional score by using Constant score, and American Shoulder and Elbow Surgeons shoulder index at just before implant removal and at final follow-up. Coracoclavicular distance was measured in acromioclavicular dislocation and bony union was evaluated in the lateral end fracture of the clavicle. RESULTS: The clinical outcomes and range of motion were increased at the final follow-up compared with just before implant removal in both the lateral end fracture of the clavicle and acromioclavicular dislocation. In acromioclavicular dislocation, all cases—except one—showed maintenance of reduction after implant removal. Moreover, in the lateral end fracture of the clavicle, all cases—except one—showed bony union. CONCLUSIONS: Hook plate fixation in the lateral end fracture of the clavicle and acromioclavicular dislocation resulted in good clinical and radiological results.

Bone marrow pressure is neither arterial pressure nor venous pressure of extremity, that is thought the precapillary pressure of bone. It is different between long bone and flat bone, and is also different in various site of the bone. Author measured bone marrow pressure of 84 normal femoral heads of Korean adults for basic data of early diagnosis of avascular necrosis of femoral head. The results are followings : 1. The baseline bone marrow pressure of Korean healthy adults is average 22.5 ±7.2mmHg. 2. The most significant change of bone marrow pressure in stress test is observed at 5 min. after injection of 5cc normal saline. 3. The increase of bone marrow pressure at 5 min. after stress test was average 7.4 ±4.4 mmHg. 4. Sex and age factors do not influence bone marrow pressure.

Ultrasonographic and radiographic findings in 72 cases of pelvic masses which have been provedhistopathologically were analyzed. The results were as follows; 1. Among 72 cases, 28 cases were uterine massesand 44 cases were adnexal masses. 2. Pathologic accuracies of ultrasonographic diagnosis were 64.3% in uterinemasses, 70.5% in adnexal masses, and 68.1% in all pelvic masses. 3. Plain or IVP findings were not specific indiagnosis and showed secondary mass effects or functional disturbances. 4. Because of its high accuracy ofpathologic diagnosis and safety, ultrasonography can be regared as the most valuable and preferential study. Butin cases of cystic myomas, endometrioses, cystic missed abortions and huge masses, the accurate diagnoses weredifficult.

When bronchogenic carcinoma is coexisting with pulmonary tuberculosis, it is difficult to differentiate bronchogenic carcinoma from pulmonary tuberculosis radiologically. Thus, the object of this study is to define differential diagnosis of bronchogenic carcinoma by computed tomography. We analized CT scans of 27 patients with radiologic findings of pulmonary tuberculosis and mass of which twelve cases were pulmonary tuberculosis and fifteen cases were primary lung cancer. The location of parenchymal infiltration and the mass was the same in 60%(9/15) of the primary lung cancer in cases and 83%(10/12) of the pulmonary tuberculosis cases. The common location of the mass was the both upper lobes in 92%(11/12) of the pulmonary tuberculosis cases and 53%(8/15) of the primary lung cancer cases. The common locations of the mediastinal lymphadenopathy were 4R, 2R of the pulmonary tuberculosis cases and 4R, 10R of the primary lung cancer cases. In the feature of post enhanced lymph nodes, homogenous increased density was more frequent in primary lung cancer. Measurements of the maximum thickness part of the cavity wall was not a reliable indication of malignancy.

Epidermal keratinocytes are important sources of a wide variety of cytokines that include the endothelin-1 (ET-1). Glucocorticoids have been shown to inhibit the production of several cytokines. However, their effect on ET-1 synthesis by keratinocytes is still unknown. It has been reported that ultraviolet B (UVB) irradiation stimulates both the synthesis and release of ET-1 and it was observed that ET-1 secretion by HaCat cells increased with increasing UVB exposure. In this study, the effects of glucocorticoid on ET-1 production were evaluated using cultured HaCat keratinocytes. The results showed that dexamethasone suppressed basal re-lease of ET-1. In addition, it strongly inhibited the UVB-mediated augmentation of ET-1 production. Furthermore, lincomycin slightly enhanced the inhibitory effect of dexamethasone on ET-1 synthesis.

BACKGROUND: Compared with conventional routes of delivering potent analgesics to postoperative patients, transdermal administration of fentanyl offers the advantages of simplicity and noninvasiveness. The analgesic efficacy and safty of transdermal fentanyl patch (TDFP) were evaluated postoperatively. METHOD: TDFP releasing 25 mcg/hr (Group 1) or placebo (Group 2) were applied to 40 women 6 hours before total abdominal hysterectomy under the general anesthesia. Postoperatively, self-administered intravenous fentanyl was maintained with a 20-mcg incremental dose and a 10-min. locking interval. Each group was assessed following 48 hours with respects to vital signs, VAS pain scores, hourly-used fentanyl doses, satisfaction scores and side effects. RESULT: VAS observed 24 hours, 36 hours after operation were significantly lower in group 1 than group 2. Hourly-used fentanyl doses were significantly lower in group 1 than group 2 at 2 hours, 6 hours, 12 hours and 24 hours after operation. The incidence of side effects were similar between group 1 and group 2. CONCLUSION: TDFP-25 mcg applied 6 hours before operation provides supplementary analges-ia after the postoperative period without significant side effects such as respiratory depression.

PURPOSE: Introduction of low osmolality contrast agent(LOCA) has allowed safer, more comfortable contrast-enhanced CT examination, but there has been significant increase in image degradation when evaluating the kidneys due to streaky artifact. The authors reviewed findings of contrast-enhanced abdominal and pelvic computed tomography(CT) to know the difference of renal streaky artifact between a high osmolality contrast agent (HOCA) and LOCA. MATERIALS AND METHODS: This study included two hundred contrast-enhanced CT in 200 patients, 100 performed with HOCA(meglumine ioglicate, 150ml) and 100 performed with LOCA (iopromide, 150ml). The severity of renal streaky artifact was compared between HOCA and LOCA groups. RESULTS: Of the scans performed with HOCA, 40 had no artifact, 52 had grade I artifact, 6 had grade II artifact, and 2 had grade III artifact Of the scans performed with LOCA, 23 had no artifact, 44 had grade I artifact, 29 had grade II artifact, and 4 had grade III artifact. There was significant difference in the degree of the streaky artifact depending upon the osmolality of the contrast media used(by {{{{x^2}}}}-test, P=.0001). CONCLUSION: The results of this study revealed a statistically significant increased incidence of artifacts and distortions of renal image with LOCA when compared with HOCA.
