There are some emergency situations when untested fresh blood should be transfused. Emergency blood donor tests(EBDT) have been done as an effort to protect these blood recipients from contracting transfusion associated infections in Seoul National University, Hospital. EBDT includes HBsAg, anti-HlV, STS, and ALT test. Anti-HCV test is not included because of the absence of appropriate test kit. A total of 534 tests have been done from June 1993 to August 1995. Among these, 495 tests(92.7%) have been done for blood donor screening, and 39 tests(7.3%) for emergency organ transplantation. Sensitivity and specificiy of the emergency HBsAg test were 69% and 98%, respectively. There were two RPR reactive blood donors, but no anti-HIV positive cases. Among 458 blood donors, 37 donors(8.1%) showed increased ALT level(> 45IU/L). The percent of agreement in HBsAg, elevated ALT and anti-HIV tests between emergent and routine blood donor tests, were 97.0%, 98.9% and 100%, respectively. Although false positive and false negative EBDT result may is useful, although limited, we think that EBDT is useful in protecting blood recipient from transfusion associated infections.

The authors report a case of thoracic outlet syndrome in left side. Thoracic outlet syndrome is a collective term in which symptoms and signs are due to bony and soft tissue compression of the neurovascular bundle at the thoracic outlet. It is a rare case in neurosurgical field. So we had experienced one case of thoracic outlet syndrome which was improved by transaxillary approach for resection of first rib. The clinical features, diagnostic test, radiological findings, and operative technique are presented with review of literatures.

BACKGROUND: In spite of the development of diagnostic tools, gallbladder carcinoma is often diagnosed at a late stage because of the lack of symptomatic awareness of patients in early stage. Early diagnosis and proper resectional treatment is, therefore, the most important factor for the prognosis. This study aims at the analysis of clinical characteristics and the effect of various modes of surgical treatment on long-term survival. METHODS: From January 1989 to December 1997 we operated on 132 patients with gallbladder carcinoma. Age, sex, stage distribution, clinical manifestations and mode of operations were analyzed. The cumulative survival rates were also analyzed for 107 patients who had been finally followed up, and the significance of survival difference was tested (p<0.05). RESULTS: The average age of 132 patients was 64 years old, and female patients suffered more frequent incidence than male patients by a ratio of 1.7:1. The distribution of patients according to the pathologic TNM staging showed early stage (stage 0 & I) accounted for only 9.8% whereas the advanced stages (stage II, III, IVa, IVb) accounted for the majority of the patients (90.2%). The chief complaints were abdominal pain (84.8%), indigestion, weight loss, palpable mass and so forth in a decreasing frequency order. Among the patients, 30 cases (22.7%) were irresectable, 50 cases (38%) were curative resected, and 52 cases (39%) were palliative resected. The overall cumulative survival rates of 107 patients were 53.7%, 41.7% and 30.1% for 1-year, 2-year and 5-year survival respectively. Although the 5-year survival rate of curative resected patients showed a significantly better survival rate (p<0.005) than that of non-curative resected patients, the different modes of combined radical surgery did not affect the survival rates. CONCLUSION: Combined curative resection ameliorated long-term survival of patients with gallbladder carcinoma. For the further evaluation of the efficacy of combined radical surgery on survival, more extensive data needs to be accumulated.

PURPOSE: Many investigators suggested that changes in hormonal environment in the postmenopausal women functionally or histologically effect the clitoris and vagina. We investigated the mechanism of female se xual dysfunction occurring in the decreased hormonal status, and aimed to establish and experimental base for the hormone replacement in postmenopausal women to correct sexual dysfunction. MATERIALS AND METHODS: Twenty mature female New Zealand white rabbits were randomly divided into three groups; control group, oophorectomy group, estrogen replacement group after oophorectomy. Nitric oxide synthase (NOS) activity and the degree of expression of neuronal NOS (nNOS) and endothelial NOS (eNOS), collagen content in clitoral tissues were analysed. RESULTS: nNOS and eNOS were significantly increased in the oohporectomized group while decreased in the estrogen replacement group (p<0.01). NOS activity showed the similar pattern of change (p<0.05). Oophorectomy induced a significant increase in collagen content, while the ratio of smooth muscle content was increased significantly after the estrogen replacement (p<0.01). CONCLUSIONS: Estrogen deficiency induces collagen synthesis and decreases the content of smooth muscle in clitoris, resulting in a structural relaxation difficulty. We believe that NOS becomes more active to improve the relaxation difficulty and that hormone replacement helps to restore the normal state of smooth muscle relaxation. Considering these findings, we suggest that estrogen down-regulates NOS and its activity.

Pulmonary embolism is the impaction of material into branches of the pulmonary arterial bed. It usually occurs in patients with primary hypercoagulable states or secondary hypercoagulable states like cancer, preganancy, and estrogen replacement therapy. We report a case of a pulmonary embolism in a patient with positive lupus anticoagulant who received estrogen replacement therapy. The patient was referred due to suddenly developed shortness of breath and echogenic mass densities in the right atrium on 2 dimensional echocardiography. The patient was markedly improved with intravenous urokinase and subsequent oral anticoagulant therapy. Related articles are also reviewed.

BACKGROUNDS/AIMS: The aims of this study were to evaluate risk factors for acute cholecystitis that have been previously acknowledged and to evaluate several co-morbidities, such as hypertension, diabetes mellitus, cardiovascular disease, cerebrovascular accident and end-stage renal disease for which the prevalence rate has increased in the elderly. METHODS: We retrospectively reviewed 611 patients who underwent laparoscopic or open cholecystectomy for cholecystitis between January 2005 and January 2010. The relationships between the clinical outcomes and the clinico-demographic factors were analyzed by univariate and multivariate analyses. RESULTS: The diagnoses of the 611 patients who underwent laparoscopic cholecystectomy were acute cholecystitis (n=258; 42.2%) and chronic cholecystitis (n=353; 57.8%). Male gender (p<0.000), age >50 (p<0.000), fever (p<0.000), leukocytosis (p<0.000), AST elevation (p=0.009), alkaline phosphatase elevation (p<0.000) and an elevation of total bilirubin (p<0.000) were identified as risk factors for acute cholecystitis. The presence of diabetes mellitus (p=0.002) and hypertension (p=0.019) may be risk factors for acute cholecystitis. CONCLUSIONS: For patients with risk factors for acute cholecystitis, early management, that is, early checkup and diagnosis following early cholecystectomy, is recommended before the disease progresses to an acute form of cholecystitis.

Multiple gastric caner, now considered to be a sort of multiple primary cancer by Moertel's classification, is a special type of cancer in which two or more tumor lesions arise independently from the stomach. Although its incidence is rare and it has never been reported in Korea yet, the report of multiple gastric cancer is increasing with lengthened life survival and improved diagnostic method. We recently experienced two cases of triple gastric cancer, the one in 53-years-old male who had well differentiated adenocarcinoma(EGC IIb+c) on antrum, poorly differentiated adenocarcinoma on cardia and moderately differentiated adenocarcinoma on mid-body, and the other in 65-years-old female who had two poorly differentiated adenocarcinoma on cardia and anterior wall of low body and moderately differentiated adenocarcinoma (EGCIIc) on posterior wall of low body. Triple gastric cancer is rare, so we reported 2 cases of triple gastric cancer.
