A study on branching patterns of middle hepatic artery was performed in 109 patients with A-P and oblique view hepatic angiogram, which refered to size and location of quadrate lobe in CT and SMA portography We could analyze the branching patterns of middle hepatic artery (MHA) in 100 among the 109 patients. MHA arising as a first branch of left hepatic artery was the most common pattern (50%), and MHA arising from proper hepatic artery separately one from left hepatic artery was the next common pattern (35%). MHA originating from left gastric artery, or from anterior or posterior of the right hepatic artery was seen. MHA WAS not found as an accessory or replaced artery except as replaced common hepatic artery.

Subcutaneous angiolymphoid hyperplasia is an uncommon disease characterized by eosinophilia, proliferation of the capillary vessels and lymphoid tissue and infiltration of the inflammatory cell, especially eosinophils. The etiology of the disease are obscure, but probably trauma, lower grade infection, nervous factor & hormonal status etc. The predilection sites are face, ears, scalf & neck, but rarely reported in the extremities. We experienced a case of subcutaneous angiolymphoid hyperplasia of the inguinal region and anteromedial side of the proximal thigh in a 10 year-old man who complained pain and tenderness on the above region. The patient was treated by excision with satisfactory result.

Before the 1970s there was no way to quantify the severity of head injury in groups of patients, but over the last two decades, medical care of the head-injured patient has evolved to a level at which clinical management decisions are based on actual measurement of relevant physiological variables and application of sound scientific principles. One of the most important reasons of such a progress is developments in medical technology. The technology has developed in a manner that now allows improved imaging of the brain as well as accurate measurement of variables such as intracranial pressure, cerebral blood flow, and brain electrical activity, all of which combine to greatly enhance the clinician's ability to monitor the injured brain. The author can not provide all the informations of advances that have taken place, or a comprehensive description of state-of-the-art technology hear, because of limited spaces. It is only hoped that this paper would afford a useful reference for those seeking newer concepts in diagnosis of head injury.

OBJECTIVE: To evaluate the diagnostic value of computed tomography-myelography (CTM) compared to that of magnetic resonance imaging (MRI) in patients with lumbar radiculopathy. METHODS: The study included 91 patients presenting with radicular leg pain caused by herniated nucleus pulposus or lateral recess stenosis in the lumbar spine. The degree of nerve root compression on MRI and CTM was classified into four grades. The results of each imaging modality as assessed by two different observers were compared. Visual analog scale score for pain and electromyography result were the clinical parameters used to evaluate the relationships between clinical features and nerve root compression grades on both MRI and CTM. These relationships were quantified by calculating the receiver-operating characteristic curves, and the degree of relationship was compared between MRI and CTM. RESULTS: McNemar's test revealed that the two diagnostic modalities did not show diagnostic concurrence (p<0.0001). Electromyography results did not correlate with grades on either MRI or CTM. The visual analog pain scale score results were correlated better with changes of the grades on CTM than those on MRI (p=0.0007). CONCLUSION: The present study demonstrates that CTM could better define the pathology of degenerative lumbar spine diseases with radiculopathy than MRI. CTM can be considered as a useful confirmative diagnostic tool when the exact cause of radicular pain in a patient with lumbar radiculopathy cannot be identified by using MRI. However, the invasiveness and potential complications of CTM are still considered to be pending questions to settle.

Chlamydia trachomatis is known as a major causative microorganism in non-gonococcal urethritis(NGU) in men. We examined two kinds of specimens simultaneously, endourethral swab and urine, in each patient to determine the reliability of these two different specimens for the detection of the Chlamydia trachomatis antigen in male NGU patients using ELISA method. Tota1 273 patients entered this study were divided into two groups according to sampling order of urine and endourethral swab. In group A(141 patients), we took endourethral swab first, then first portion of voided urine was caught. In group B(132 patients), endourethral swab was performed after urine sampling. Twenty five out of 273 patients(9.2%) showed Chlamydia trachomatis antigen positive in endourethral swab sample and 1 out of 273 patients(0.4%) was positive in urine sample. There was no significant difference of antigen positive rate of endourethral swab examination between group A and group B. Our data suggest that examination of endourethral swab is more reliable method for the detection of the Chlamydia trachomatis antigen than urine examination in male NGU patient.

The management for herniated lumbar disc has been improved steadily since the standard discectomy was introduced at the early stage of this century. The therapeutic use of standard discetomy has been critisized by some investigators because of its incasiveness and potential postoperative sequele. Recently various non-invasive mean were developed, however there are still some disadvantages with them such as high cost and thire limitation of disc removal. In the present study fifty-nine cases managed with microsurgical discetomy were presented, all performed by one surgeon and analysed by the other. The operative results, assessed 6 months postoperatively, showed that the microdiscecetomy was of good quality, comparable to the results of the standard discectomy reported by others. Patients have discharged early(less than 10 days) and returned to their usual activities quickly(less than 3 weeks). The advantage of this technique is its capacity to preserve better integrity of normal tissue and to impose less trauma on the body. Furthermore it may be more cost-effective than any other surgical managements available. It can be concluded that microsurgical discectomy represents one of the best refinements of standard discectomy even if it has also some negative points.

The cerebroprotective effects of mild to moderate hypothermia(about 32degreesC) in brain ischemia have been well established. Taking into consideration of potential deleterious systemic effects of total body cooling, selective brain cooling(SBC) can be considered as an alternative mean, and recently the protective effects of SBC in focal cerebral ischemia have been reported. However, there has been no attempt to draw a comparison of antiischemic and systemic effects between systemic hypothermia(SH) and SBC. The present study investigates the effects of SH and SBC on the physiological variables, neurological outcome, and the volume of brain infarction and edema, and compares each other. In thirty adult male Sprague-Dawley rats weighing 300-400g, permanent middle cerebral artery(MCA) occlusions were performed. Five groups of animals were studied; group 1, normothermic control(n=6); group 2, systemic hypothermia for 30min(n=6); group 3, selective brain cooling for 30min(n=6); group 4, systemic hypothermia for 60min(n=6); and group 5, selective brain cooling for 60min(n=6). In the hypothermia groups, active cooling was performed 15min following MCA occlusion. During the experimental procedures, the physiological variables such as mean arterial blood pressure and blood gases were continuously monitored. Twenty-four hours following MCA occlusion, the rats were sacrificed. Eight predefined coronal sections were stained with hematoxylin-eosin and the volume of ischemic damage and edema was computed. The results are as follows: 1) There were no differences in the physiological variables between SH and SBC groups. 2) In the hypothermia groups, neurological outcome was much better(p<0.05) than that in the control. 3) The volume of ischemic damage was significantly reduced to 49.2%(p<0.05) in group 4 and 26.7%(p<0.05) in group 5, compared to group 1. 4) Ischemic brain edema was significantly attenuated in group 4(23.6%; p<0.05) and group 5(7.8%; p<0.05), compared to group 1. These results reveal that systemic hypothermia may exert more beneficial effects upon focal cerebral infarction without significant systemic complication than selective brain cooling.
