Most of foot pain occurs by the entrapment of the tibial nerve and its branches. Some studies have reported the location of the tibial nerve; however, textbooks and researches have not described the posterior tibial artery and the relationship between the tibal nerve and the posterior tibial artery in detail. The purpose of this study was to analyze the location of neurovascular structures and bifurcations of the nerve and artery in the ankle region based on the anatomical landmarks. Ninety feet of embalmed human cadavers were examined. All measurements were evaluated based on a reference line. Neurovascular structures were classified based on the relationship between the tibial nerve and the posterior tibial artery. The bifurcation of arteries and nerves were expressed by X- and Y-coordinates. Based on the reference line, 9 measurements were examined. The most common type I (55.6%), was the posterior tibial artery located medial to the tibial nerve. Neurovascular structures were located less than 50% of the distance between M and C from M at the reference line. The bifurcation of the posterior tibial artery was 41% in X-coordinate, -38% in Y-coordinate, and that of the tibial nerve was 48%, and -10%, respectively. Thirteen measurements and classification showed statistically significant differences between both sexes (P<0.05). It is determined the average position of neurovascular structures in the human ankle region and recorded the differences between the sexes and amongst the populations. These results would be helpful for the diagnosis and treatment of foot pain.

The knowledge of arterial patterns of donor and recipient sites is very important for performing a flap surgery. In order to perform a flap surgery using the rectus abdominis muscle knowledge of the distributions, tributaries, and anastomoses of the inferior epigastric artery is necessary. The aim of this study was to establish the clinical and anatomical characteristics of the inferior epigastric artery for flap surgery in Koreans. Sixteen fresh cadavers were injected bilaterally with a radiopaque dye solution through the brachial and popliteal arteries, radiographic images were obtained after the anterior abdominal wall was removed surgically. Subsequently, the anterior abdominal walls of the cadavers were dissected and measured by using metric and non-metric methods. In a majority of the cadavers (83.9%), the inferior epigastric artery had only one main stem. Between the umbilicus and the xiphoid process, the most common type of the anastomosis was multiple anastomoses (Type IV, in 32.1% of the cases), followed by no anastomosis (Type I) and single anastomosis (Type II) in 25% of the cases, respectively. The intramuscular branch of the inferior epigastric artery originated from below the umbilicus in 60.7% of the cases and above it in 39.3% of the cases. The peritoneal branch was further divided into 3 types: lateral, medial, and umbilical. One of them coexisted with other branch of specimen. The peritoneal branch commonly originated from the intramuscu-lar branch. The perforating branch, with an external diameter of greater than 0.5 mm, was clinically significant, was dis-tributed around the umbilicus. The number of arterial branches directly perforating the rectus abdominis muscle was greater than that of those traveling anteriorly. The results of this study may enhance the anatomical knowledge of clinicians with respect to flap surgery or surgical treatments involving the anterior abdominal wall.

PURPOSE: The aim of this study was to compare the film thicknesses of several resin cements as a function of time after mixing and to examine the effect of working time on the film thicknesses. MATERIALS AND METHODS: The film thickness (microm) of 4 resin cements (n=10), 1 composite resin (Panavia F 2.0), 3 self-adhesive resin (Clearfil SA luting, Zirconite, RelyX U200) cements was measured at 20-second intervals after mixing of the cements up to 200 seconds under a load of 50 N. Linear regression was fitted to verify the effect of working time on the film thickness of each cement. Data were compared to the working time recommended by manufacturers using Wilcoxon test (alpha=.05). RESULTS: All of the materials showed a positive linear correlation between the film thickness and working time. There was no statistically significant difference between the working time based on our results and the values recommended by the manufacturers even though there was a discrepancy between those two values. CONCLUSION: The film thickness of resin cements could increase with the increase of working time. Working time to meet the ISO standard of 50-microm maximum film thickness could be different from the manufacturer's recommended value.

Microscopic analysis of bone is very useful method for estimating age at death of individual identification, diagnosing metabolic disorder or dietary deficiency in bone tissue, and differentiating human bone or not when applied to fragmentary skeletal remains. The purpose of this study was to establish a systematic method for preparing bone tissues by manual grinding method and offer help in application of related histomorphometric field such as estimating age at death. For this, human bone tissues of rib and femur from cadavers were prepared and considered histomorphological variations of osteon with light microscope. As results of this study, Type II osteons, smaller versions of Intact osteons (Type I) that form by radial remodeling of a preexisting Haversian canal, were distinguished from double-zonal osteons, one of the osteons that exhibit hypercalcified ring within their concentric lamellae, by the lack of an internal reversal line and the parallel contours of lamellae, and it is possible to suggest metric basis for drifting osteons as counting one osteon with the exception of size measurement. By applying this method of present study, one could easily make a bone tissue all oneself that would be helpful for establishing basic data in physical and forensic anthropology.

We report a rare case of meningioangiomatosis in a 22 year-old man who has refractory partial seizures. Seven of 11 seizures had ictal onset zone at the perilesional medial and orbitofrontal areas of frontal lobe and 4 seizures arose from the mesial temporal area. After having lesion resection and an anterior temporal lobectomy with amygdalohippocam-pectomy, the patient no longer suffered from seizures. The epileptogenic foci were found not only in the intra-/peri-lesional area but also in remote area.

The purpose of this research is to establish metric standards for the determination of sex from the upper limb bones of Korean. We took a set of eleven measurements on each of 175 right sides of adult skeletons chosen at Korean sample. Classification accuracy dropped only one or two individuals when only vertical head diameter of humerus is used. Variables in relation with maximal length were less accurate than head diameter of humerus. Two variables were selected by the stepwise procedure: maximal length of humerus, vertical head diameter of humerus. The combined accuracy was 87%. This study of modern Korean skeletons underscores the need for population-specific techniques, not only for medicolegal investigations, but also for the study of population affinities and factors affecting bone configurations.

Recently, a new classification of eosinophilic folliculitis (EF) was made as follows: classic eosinophilic pustular folliculitis (EPF; Ofuji's disease), HIV associated EF, pediatric EF, fungal EF and miscellaneous group. A 10-year-old boy presented with a 2-week history of pruritic, erythematous papules with a plaque on his left cheek. A biopsy specimen revealed folliculitis with predominant eosinophilic infiltrates. Clinicohistopathologically, the most compatible diagnosis was eosinophilic pustular folliculitis and subsequently, dapsone was administered for 2 weeks but the lesion showed insufficient improvement, and the original confluent papules changed to a KOH-positive, arciform scaly lesion. A serial section from the paraffin block of the first biopsy, which had been histopathologically negative for fungal hyphae in the first, revealed hyphae in a single follicular canal in only one section out of 100 sections examined. This is believed to be the first reported case of fungal eosinophilic folliculitis in Korea.

BACKGROUND: In aerometabolic process, the human heart mainly utilizes free acid as fuel. During anaerobic process, lactate production by the myocardium is increased and accumulates in the myocardium. Thus it decreases the contractility of myocadium. Therefore in patients with ischemic heart disease, lactate prodution must be increased by the myocardium during myocardial ischemia. During paroxysmal supraventricular tachycardia, patients frequently experience chest pain and ST segment depression suggesting acute myocardial ischemia. However it occurs on a physiologic basis independent of ischemia. The purpose of this study was to assess whether tachycardia induced by artial pacing produces myocardial ischemia in patients without evidence of ischemic heart disease. METHODS: Between May 28, 1996 and August 13, 1996, at the University of Keimyung, Dong-San Medical center, 15 patients(male 9, female 6, mean age of 38 years) with palpititation underwent electrophysiologic testing and had radiofrequency cather ablation. There were no evidence of ischemic heart disease. Right artrial pacing was done with lengths of 500msec, 400msec and 350msec in each 5 patients. A 12 lead electrdcardiogram, left ventricular enddiastolic pressure, blood from femoral artery and coronary sinus for lactate determinations and blood gas analysis were dbtained simultaneously. They were obtained at baseline, at 1, 5, 10 and 15 minute of atrial pacing and at 1, 5, 10 minute after cessation of pacing. RESULT: Significant changes were not observed in , , concentration of , pH and saturation. In all patients, mean percent lactate extraction was above 10% and not significantly changed during atrial pacing. However ST segment depression was significantly progressive during atrial pacing and according to decrease the cycle length(p<0.05), also left ventricular end-diastolic pressure was significantly decreased during atrial pacing(p<0.05). Conclusion: Therefore tachycardia induced by atrial pacing for 15 minutes did not produce myocardial ischemia in patients without evidence of ischemic heart disease. Depression of STsegment during supraventricular tachycardia or atrial pacing, in patient without underlying heart disease is necessary to inveestigate what makes this phenomenon.
