BACKGROUND: Esmolol has been applied to lower myocardial oxygen consumption and creates a quieter operative field by reducing systemic blood pressure and heart rate but can cause a certain amount of hemodynamic instability during minimally invasive direct vision coronary artery bypass graft (MIDCAB). The aim of this study was to compare the hemodynamic differences between two methods; inducing hypotension and bradycardia between esmolol infusion alone, and concomitant use of neostigmine during MIDCAB anesthesia. METHODS: Twenty MIDCAB patients were randomly allocated into two groups, group E (n = 10) receiving esmolol 0.3 mg/kg/min, group EN (n = 10) receiving esmolol 0.2 mg/kg/min and neostigmine 1.0 mg for induced hypotension and bradycardia during coronary anastomosis. The hemodynamic parameters were evaluated 10 minutes after induction of anesthesia (T1), 10 minutes after beginning of operation (T2), 5 minutes before the end of anastomosis (T3) and 10 minutes after the end of anastomosis (T4). Data were analyzed by ANOVA test for intragroup comparisons, and by T-test for intergroup comparisons with significance set at a P value of < 0.05. RESULTS: Heart rate significantly decreased at T3 in both groups and more in group EN. Systolic blood pressure decreased at T3 in both groups and there were no group differences but more episodes of extreme hypotension in group E. The cardiac index significantly decreased at T3 in both groups and more in group E. There was a small but significant increase in pulmonary capillary wedge pressure at T3 and T4 in group E and no change of central venous pressure in both groups. CONCLUSION: Concomitant use of neostigmine during esmolol infusion produces more reliable induced hypotension and bradycardia than esmolol infusion alone for MIDCAB anesthesia in terms of prevention of myocardial ischemia and easiness of anastomosis technique.

Hydroa vacciniforme is a very rare photosensitivity disorder. The primary skin lesion is a vesicle or bulla which then heals with vacciniform scarring. We report a case of hydroa vacciniforme recurred after 3 years period of quiescence in a 20 year-old man who had had history of the disease from the age of two. The duplication of the natural lesion, clinically and histologically, was successfully made by artificial UV-A irradiation on the patient's back.

Leiomyomas of vagina and vulva are rare solid tumors, but most common mesenchymal tumors in adult woman. Most of the reported cases have been benign. The tumors were firm, well-defined submucosal masses in a majority of patients. We experienced two cases of vulvar and vaginal leiomyoma, thus it is presented with a brief review of the cases and its literatures.

6.The Studies in Bedside Eletrolyte Monitoring with VIA 1-01.
Korean Journal of Anesthesiology 1993;26(1):99-105
In case of cardiopulmonary bypass, organ transplantation and massive transfusion, the electrolyte(Na+, K+, Ca++) and pH are very changeable, and it is very important to correct the pH and electrolyte immediately. We studied the bedside electrolyte monitoring with VIA(Vascular Intermittent Access) 1-01 and its accuracy validation. We selected 13 patients who went an open heart surgery in the Seoul National University HospitaL The patient was catheterized with 16 G triple lumen catheter into the SVC-right atrium junction via right internal jugular vein. Then we connected VIA 1-01 to one lumen. The electrolyte samplings were done during perianesthetic period. The electrolyte values(Na+, K+, ionized Ca++) of each sample was measured by laboratory, NOVA of PAR(postanesthetic recovery room) and VIA 1-01. We compared the values with correlation. The Pearson product-moment coefficient(r) of laboratory vs VIA 1-01 are 0.9073(Na+), 0.9471(K+) 0.6485(Ca++). The r of NOVA vs VIA 1-01 are 0.6348(Na+), 0.9330 (K+), 0.5206(Ca++ ). The r of laboratory vs NOVA are 0.6719(Na+), 0.9532(K+ ), 0.8221(Ca+). All pvalues of r were lower than 0.01. We conclude that bedside electrolyte monitoring with VIA l- 01 is very useful to critically ill-patient and major operations during anesthesia and it improves the prognosis of such patients.

A 44 year-old male without a specific past history demonstrated violaceous colored. angulated flat papules in a zosteriform arrangement along the medial aspect of left arm and upper anterior chest for 3 months. In addition, whitish patches with a lace-like pattern were seen on the buccal mucosa. The histopathologic findings were characteristic of lichen planus. The zosteriform lichen planus is a rare variant of lichen planus, Especially, it has been rarely observed in cases that developed without a previous history of herpes zoster or factors that lead to the Koebner phenoinenon In this context, it piqued our scientific curiousity enough to investigate it.

Upper gastrointestinal(UGI) bleeding was critical disease that was commonly found in emergency department and needed more early diagnosis and rapid treatment for decreasing mortality and morbidity. It's causes and frequencies here affected by many factors, but the majorities were caused by peptic ulcers and esophageal-gastric varices. With development of economy and medical services, new drugs and endoscopic interventions, the treatment of patients with UGI bleeding was more improved. So I would like to evaluate the change of causes and frequencies of UGI bleeding and the associated clinical findings. A total of 1,546 patients presented with UGI bleeding in emergency department of Yeungnam university hospital during the five years from Jan. 1991 to Dec. 1995 were clinically reviewed by charts and compared with previous seven years report from Jan. 1984 to Dec. 1990 in the same hospital. The ratio of male to female was 6.1:1 and slightly increased in comparison with previous seven years. The incidences in 6th and 5th decades were highest(54.4%) as like as previous seven years. Age distribution of duodenal ulcer bleeding, Mallory-Weiss tear and acute gastric mucosal lesion were developed in lower decades than the others. The causes of UGI bleeding were caused by esophageal varix(45.4%), peptic ulcer(38.8%), Mallory-Weiss tear(4.3%), gastric cancer(3.8%), others(3.1%), acute gastric mucosal lesion(2.7%), undetermined causes(1.8%) in defending order of frequencies. The proportion of esophageal varices was increased from 36.6% to 45.4%, but that of peptic ulcer was relatively decreased from 47.6% to 38.8%. And the annual distribution of varices was increased, however the annual distribution of peptic ulcers was increased. Although the ranking of annual distribution of gastric ulcers and duodenal ulcers were not changed compared to previous study and the frequency of gastric ulcers was increased since 1992, but additional follow-up was needed. Seasonal variations were found that upper gastrointestinal bleeding was increased in fall and peptic ulcer bleeding was increased significantly in summer and fall, however, varix bleeding was less frequent in summer time as like as previous seven years. Emergency endoscopic examination was performed within 6 hours far 54.5%, 24 hours for 90.8% and this reacts were to be like previous results, 57.5% and 90.7% respectively. Findings of emergency endoscopic examination were active bleeding focus(21.2%), blood clot(7.9%), exposed vessels(13.3%), flat blood spot(6.4%) and lesion without evidence of bleeding(51.3%). Endoscopic findings of active bleeding were easily seton when examination was perfomed within 24 hours. Blood transfusion was performed in 67.3% with average 2.1 units. When the causes of bleeding were due to varix and marginal ulcer, more amounts of blood were transfused than the others. In previous seven years, blood transfusions were performed in 71.2% with average 5 units and more amounts of blood were transfused in gastric cancer and varix bleeding.

BACKGROUND: The optimal management of malignant obstruction of the left colon and rectum is controversial. METHODS: A retrospective study was performed of 33 patients who underwent one-stage operation(n=11), staged operation(n=20), and palliative colostomy(n=2) at Kwangju Christian Hospital between January 1992 and December 1996. RESULTS: Eleven patients underwent one-stage operations(7 cases with anterior resection, 3 cases with left hemicolectomy, 1 case with Miles' operation). In this group, postoperative morbidity was 36.3% including 1 wound infection(9.0%), 1 anastomotic leakage (9.0%), 1 postoperative intestinal obstruction and 1 pulmonary complication, but there was no postoperative death. The average of hospital stay in this group was 18.1 days and the first day of normal diet was 6.0 days. Twenty patients underwent staged operations including 12 cases of Hartmann's procedure. In this group, postoperative morbidity was 35.0% including 3 wound infections(15.0%), 2 pulmonary complications(10.0%), 1 parastomal hernia and 1 fistula. There were two postoperative deaths as a result of sepsis. The average of hospital stay in this group was 34.9 days and the first day of normal diet was 6.8 days. CONCLUSION: We believe that one-stage operation was of value in management of malignant obstruction of the left colon and rectum in selected patients.
