Intraspinal neurenteric cysts are rare congenital lesions that results from abnormal separation of germ layers in the third week of embryonic development, which may cause spinal compression. Although, the diagnosis of neurenteric cyst was very difficult prior to operation, MRI has proven to be a useful imaging modality in detection, localization and characterization of intraspinal neurenteric cysts. We recently experienced intraspinal neurenteric cyst in two patients who presented with progerssive quadriparesis. Myelography, CT myelography and MRI were taken and complete excision was performed. The MRI findings are presented and the literature is reviewed.

PURPOSE: A common finding of carotid artery on magnetic resonance angiograms(MRAs) is a signal dropout along the posterior wall of carotid bulb due to reverse flow. The purpose of this study is to evaluate variable flow patterns on bifurcated carotid arterial phantoms using steady-state flow. MATERIALS AND METHODS: We designed phantoms of a bifurcated carotid artery with acrylic materials. Flow patterns were evaluated with axial and coronal imaging of MRA(2D-TOF, 3D-TOF), color Doppler imaging, and computational fluid dynamics (CFD) within the phantoms constructed of an automated closed-type circulatory system filled with 4% sugar solution. These findings were compared with findings obtained from normal volunteers. RESULTS: Axial 3D-TOF MRA images exhibited closer resemblance to the contour of the inner wall of phantoms when compared to coronal 2D-TOF MRA imaging. However, 2D-TOF MRA showed good contrast difference of signal intensities between forward flow area and reverse flow area. Dark zones with reduced signal intensities due to reversed flow were separated from the outer wall of the internal and external carotid arteries by a thin layer of forward flow along the wall on the source slice image of MRA. The general hemodynamics of the phantoms on MRA were identical to hemodynamics on color Doppler imaging and CFD. The results obtained with the phantoms matched the findings on normal volunteers. CONCLUSION: Although representations of bifurcated carotid arterial phantoms on axial 3D-TOF MRA were excellent if ideally desinged, the zone of reversed flow could be a significant factor in creating distorted image when the zone of reversed flow contacted directly with curved or deformed arterial wall.

Primary biliary cirrhosis is frequently associated with a variety of disorders presumed to be autoimmune in nature, such as Sjogrens syndrome, scleroderma, rheumatoid arthritis, systemic lupus erythematosus, and autoimmune thyroiditis. Scleroderma has been recognized in association with primary biliary cirrhosis. Most cases present as the CREST (calcinosis cutis, Raynauds phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia) syndrome. Isolated pulmonary hypertension develops in a small proportion of patients, nearly all of whom have limited cutaneous involvement. We report a case who has diffuse scleroderma associated with primary biliary cirrhosis and isolated pulmonary hypertension.

The authors analysed the CT findings in 75 cases diagnosed as gastric carcinoma by U.G. I.S. or endoscopy in a 3)1, year period. The comparative analysis betw~en CT findings and surgical pathologic findings was done in 55 cases who underwent surgery. 20 cases could not be operated upon because of distant metastasis. The gastric carcinoma was devided into 4′ stages according to the staging system of the American joint Committee on Cancer. The CT findings were then compared and the following results noted : 1. The relationship with gastric wall thickening and penetratioil degree of tumori no thickening (Iesser than 1.0 cm) of 3 cases showed all of T1, 11 of localized thickening (1. 0.1 .5cm) showed 7 of T2, 38 of localized thickening (more than 1.5 cm) showed 37 of T3 and 3 of diffuse thickening showed all of T4a. 2. The accuracy of Iymph node detection by CT scan, 1) Regionaf tymph node showed 86% in operative f in ding and 73% in pathologic. 2) Extragastric Iymph node showed 87% in operative finding and 89% in pathologic. 3) Retro-peritoneallymph node showed 96% in operative finding and 95% in pathologic. ic. 3. In operated cases, there was one case of false positive distant metastasis and three false negative cases. 20 cases of non-operated cases showed distant metastasis such as liver, lung or kidney. 4. 55 cases were classified as stage 1 in 4 cases, 11 in 18, 111 in 23 and IV in 10 by pathologic findings, and 1 in 3, 11 in 24, 111 in 19 and IV in 9 by CT. The overall accuracy by CT stagi ng is 75%. 5. Among a total of 75 cases, there were 46 operable cases by CT finding an d 43 operabl e cases by pathologic staging. There we re 29 inoperable cases by CT finding and 27 cases by pathologic staging. Therefore, there was a 93% overall accuracy by CT stagi ng in terms of determination of operability. 6. The accuracy of adhesion into adjacent structure by CT finding was 69%. compared with operable finding.

The following are summary of the clinical observations on 184 pregnant women underwent cesarean section under general and spinal anesthesia. 1. Ages of pregnant women ranged from 18 to 45 years The second and third decades. comprised 94% of all cases. 2. 83% of the cases were emergency and others were elective operations. 3. Surgical indications revealed dystocia in 43%, hemorrhage in 35%, and others in 22%. 4. 92 cases were performed by general anesthesia, 88 cases by spinal and the remains by local. 5. Apgar scores checked one minute after delivery were as follows. That was Poor category (0 to 4): 42% Fair category (5 to 7): 19% Good category (8 to 10): 39% Resuscitation of Apgar score 0 babies were successful in 8 cases.

OBJECTIVES: This study was designed to integrate the results of community based studies which assessed a relationship between depression and alcoholism by meta-analysis. METHODS: We identified the previons studies and included in meta-analysis by searching MEDLINE. Overall, 21 results of the studies for relationship between depression and alcoholism were selected for quantitative meta-analysis. Before the integration of the each effect size of the relationship between depression and alcoholism, a homogeneity test was conducted. For the publication bias, we also conducted the analyses of funnel plot, normal quantile plot, rank correlation test and the fail-safe n. RESULTS: We used the random effect model to estimate the overall effect size, because the homogeneity of studies was rejected in a fixed effect model. Our quantitative meta-analysis yielded that integrated odds ratio between depression and alcoholism was 2.42 (95% C.I. 1.98-2.97). From the results of analyses of the publication bias, the probability of publication bias is considered low. CONCLUSION: The published evidences suggested that there may be a significant positive relationship between depression and alcoholism.

Although crystalloid solutions such as Ringer's lactate have become the standard for initial volume replacement after hemorrhage, it is controversy whether this fluid alone restores and maintains the depressed physiologic function after severe hemorrhage. Six anesthetized dogs were bled(35ml/kg) and resuscitated with Ringers lactate solution (100 ml/kg). Physiologic variables are measured initialy, after hemorrhage, after resucitation. Compared with initial value, after resuscitation data show marked reduction in hemoglobin, oxygen carrying capacity, vascular resistance, and electrolyte. But cardiac output and blood gas analysis data was not changed. Prothrombin time and partial thromboplastin time was prolongated. From this study crystalloid resuscitation in severe hemorrhagic shock restore cardiac output and perfusion, but fail to maintain adequate oxygen carrying capacity.
