We report a rescently experienced case with atypical radiologic manifestation of solid and papillary epithelial neoplasm of the pancreas in a 37 years old female patient. The tumor had heavy calcification on its capsule wall and septa. Instead of the usual encapsulated lesion with partly solid and partly cystic-hemorrhagic components, the lesion consisted of numerous fine cavitations containing air without fluid component except focal abscess fluid.

BACKGROUND: Alcohol has much effect on our lives as a taste food that people in almost all of the world generally have had. The effects of alcohol cause social problems as well as physical and psychological problems. Recently, interest about drinkirg increasingly rises as the rate of drinking accident increases in Korea. For this, our study examined the amount of alcohol consumption and early at-risk alcohol intake. METHODS: The prepared questionnaire was presented to subjects who were employees in Inchon . The anonymous, self-administered questionnaire was composed of questionnaire concerning alcohol consumption, early at-risk alcohol intake and doctor's role in drinking behaviour. RESULTS: Among 305 subjects, there were 189 (62%) men, 116 (38%) women whose mean age was 37. 9years. 87(28.5%)subjects were classified as high alcohol group and 218(71.5%) low alcohol group. High alcohol group was defined as early at-risk alcohol intake for men who were consuming 135g of alcohol per day, 630 per week and for women 90g per day, 270g per week. Low alcohol group was defined as early at-risk alcohol intake for men whose consumption was 90g per day, 450 per week and for women 45g per day, 270g per week . Mean alcohol consumption of drinker was 158.9g per week. 3 days per week people should not drink in order to avoid risk Although 54% of respondents thought doctors should ask about their drinkirg habits, only 16.4% of respondents reported ever being asked about alcohol intake on the subject. CONCLUSION: Early at-risk drinking subject in the study was much more than those suggested by NIH(National Institutes of Health). We conclude that primary care physicians should take more interest in screening, treating and preventing alcohol related problems and advise and educate patients to cut down or quit drinking.

Pheochromocytoma stems from the chromaffin cell and mostly is located in the adrenal medulla. It is an important cause of secondary hypertension due to correction of hypertension by a resection of the tumor. Because it produces and secretes catecholamine, it bothers anesthesiologists with excessive hypertension, tachycardia and arrhythmia during the anesthetic period. Therefore, anesthetic management is directed to avoid these conditions. We report a case of bilateral pheochromocytoma successfully managed intraoperatively with an infusion of nicardipine and an intermittent esmolol injection.

BACKGROUND: Patients with chest pain are common among outpatients. Several researches shows that chest pain patients can suffer from psychiatric illnesses such as hypochondriasis, depression, anxiety, somatization, panic disorder and so on. This study aims to examine the pschogenic symptoms in patients with noncardiac chest pain METHODS: In this study, the 98 people who have undergone treadmill test for chest pain during the three months from June 1st to September 30 of 1998 were selected, and the 98 patients were asked to respond to the prepared questionnaire and SCL-MPD(symptom check list-minor psychiatric disorders) before they underwent treadmill test. And then, they were classified into two groups. One group consisted of patients with noncardiac chest,pain, and the other group of patients with cardiac chest pain. These two groups were compared in 10 measures, and the compared results were analyzed by t-test. RESULTS: Among the 25 patients with cardiac chest pain, 15 patients were males and 10 patients (38%) were females, and among the 44 patients with noncardiac chest pain, 31 patients (70%) were males, 13 patients (30%) were females. The average age was 47 years old. The average age in patients with noncardiac chest pain was 48, and the 46 for those patients with cardiac chest pain . In the statistical analysis between the patients with cardiac chest pain and those with noncardiac chest pain, significant difference(p<0.005) was shown in the measures such as somatization, depression, phobic anxiety, obsessive-compulsive, neurasthenic, hypochondriacal, anxiety, anger-hostility, interpersonal sensitivity. CONCLUSIONS: As in the analysis the patients with noncardiac chest pain showed significant difference in the symptom check list-minor psychiatric disorder compared to those with cardiac chest pain. We conclude that primary care physician should take more interest in evaluating psychiatric symptoms in patients with noncardiac chest pain.

To determine Whether neoatigmine had different effecta in pediatric patients and adults during vecuronium neuromuscalar blockade, the rate of recovery following neostigmine admimistration was compared in children (n=10, group I) and adulta (n=10, group II) during nitrous oxide-Halothane anesthesia. After induction of anesthesia, patients received 100 ug/kg of vecuronium. Reversal was attempted at 10% spontaneous recovery of twitdi height, Neostigmine (30 ug/kg in children, 40 ug/kg in adults) was injected in a single bolus dose. During the first few minutes following neostigmine admimistration, no differences were obaerved between the two groups, Ten minutes after neostigmine admmistration, the first twitch (mean+/-SD) reached 95+/-2%, 93+/-2% of control value in children and adults respectively. The more complete recovery of the eighth minutes in children could be due to the faster rate of spontaneous recovery from vercuronium induced neuromuscular blockade in children.

BACKGROUND: The renin angiotensin syaimstem plays an important role in hypertension. Therefore, the purpose of this study was to investigate the comparison of responsiveness to angiotensin II (ANG II) in isolated renal proximal convoluted tubules of spontaneously hypertensive (SHR) and Wistar Kyoto (WKY) rats. METHODS: Intracellualr calcium concentration ([Ca2+i) was measured using Fura- 2/AM, inositol trisphosphate (IP3) accumulation was determined by radioimmuno assay and cellular ATP content measured using the microchemilunescene method in renal proximal tubule suspension or isolated renal proximal tubules. RESULTS: When measured the ANG II-induced [Ca2+i, the young rats showed a greater response to ANG II than adult rats in both strains. The ANG II (10-7 M)-induced [Ca2+i transient in the cortical tubule suspension from adult SHR was significantly lower than that in age-matched WKY. In isolated proximal tubule segments, ANG II-induced [Ca2+i increment was only observed in S1 segments. Comparing responsiveness to ANG II in SHR and WKY, similar phenomenon was observed as experiment using tubule suspension. IP3 accumulation by ANG II also attenuated in adult SHR. The 20-minutes incubation without any exogenous substrate in proximal convoluted tubule (S1) significantly decreased cellular ATP content and ANG II (10-7 M) inhibited decrement of cellular ATP level. The effect of ANG II on cellular ATP restoration was disappeared by the treatment with losartan. CONCLUSION: From these results, the responsiveness of ANG II to AT1A receptor is attenuated in the proximal convoluted tubules of adult SHR comparing the age- mached WKY.

Clostridium difficile is the most common nosocomial pathogen of the gastrointestinal tract. Pseudomembranous colitis occurs as a result of a severe inflammatory response to Clostridium difficile toxins. Pseudomembranous colitis is an increasingly frequent cause of morbidity and mortality among elderly hospitalized patients. Diarrhea is the most common manifestation. According to the literature, stools are almost never grossly bloody, and range from soft and unformed to watery or mucoid in consistency. We now report the cases of three patients with pseudomembranous colitis whose main clinical manifestation was hematochezia.
