We experienced a case of a primary aortoduodenal fistula, which was successfully diagnosed and repaired. This diagnosis must be considered in cases of gastrointestinal bleeding with an abdominal aortic aneurysm. If the correct diagnosis can be made promptly, surgical repair of the fistula is possible.

This study was designed to investigate whether recruitment of physicians and dentists has been restricted to a social network, such as familial or kinship groups. The data was collected through a self-administered questionnaire survey distributed to a sampling of general physicians, specialists (internists, surgeons, other specialists), and dentists in August 1990. The major findings are as follows: 1) Total number of respondents was 405; of these, general physicians made up 48.9%, internists 10.4%, surgeons 15.8%, other specialists 4.9%, and dentists 20.0%. 2) 38.5% of the respondents had physicians or dentists in their immediate family or were related in some way to one. Those from urban areas, whose parents were highly educated, and whose father was a professional had more physicians or dentists in their family or kinship. 3) Parents of 7.1% of the respondents, brothers or sisters of 10.1%, grand parents of 1.7%, uncles or aunts of 7.9%, and cousins of 22.0% were physicians or dentists. 4) The majority of physicians or dentists in familial or kinship network specialized in surgery, 32.3%, followed by internal medicine ; current worksites were noted as clinics by 30.8%, followed by general hospital, university hospital, and so on. The respondent's major discipline tended to follow familial or kinship example. Consequently, it was concluded that physicians and dentists have been recruited within restricted familial or kinship network.

Total knee arthroplasty has been associated with marked blood loss despite the use of a tourniquet and minimal postoperative suction drainage. The purpose of this study was to determine the effect and complication of topically applied fibrin glue(Tisseel) on blood loss. Fibrin glue was used to coat the operative site with a fibrin clot to determine the effect on postoperative blood loss. We reviewed 71 cemented total knee arthroplasties from June, 1996 to April, 1998. 71 cases of the total knee arthroplasty was composed of 31 case without fibrin glue(Group I), 12 cases with 5cc fibim glue(Group II) and 28 cases with 10cc fibrin glue(Group III). Hemoglobin and hematocrit were assayed before surgery and 1 day after surgery, and we compared the amount of the total blood loss, autotransfusion in each groups. The average amount of total blood loss is 1362cc(775-2150) in group I,1164cc(505-1670) in Group II, 772 cc(380-1410) in Group III. The average amount of autotransfusion is 72.7%(990cc) of total blood loss in group I, 91.4%(1064cc) in group II, 90%(650cc) in Group III, and Group II & III can autotransfuse above 90% of total blood loss. No significant difference was noted in preoperative and postoperative hemoglobin and hematocrit between each groups. Administration of fibrin glue gives a significant reduction of blood loss, enables autotransfusion about 90% of total blood loss, and provide the advantages of safety from transmission of viral diseases and from immunologic reaction. In conclusion, fibrin glue is a safe and effective hemostatic agent for bleeding control after cemented total knee arthroplasty.

Alcohol has extensive effects on sleep and daytime sleepiness. Alcohol has a sleep inducing effect and the effect of increased non-REM sleep and suppressed REM sleep during the first half portion of night sleep, but alcohol induces the effect of decreased non-REM sleep and increased light sleep and frequent awakenings and REM rebound during the second half portion of night sleep. Alcohol provokes chronobiological change such as the changes of amplitude or the phase shifts of hormones or core body temperature. The sleep disruption resulting from alcohol drinking may lead to daytime fatigue and sleepiness. The elderly are at particular in the increased risk of alcohol-related sleep disorders because they achieve higher levels of alcohol in the blood and brain than do younger adults after consuming an equivalent dose. Bedtime alcohol consumption among older adults may lead to unsteadiness if walking is attempted during the night, with increased risk of falls and injuries. Continued alcohol use for sleep induction often induces aggravation of insomnia, alcoholism or sleep related breathing disorders such as obstructive sleep apnea. Alcohol should not be used as substitution of sleep pill because of the dependence and tolerance for sleep inducing effect, and the sleep disruption produced by alcohol withdrawal.

This study examined burdens of primary family carcgivcrs of paticnto with cerebrovascular accidents (CVA) along with related factors. In addition, their needs for support group intervention were assessed to develop a support group to reduce the burdens of caregiving. Eighty-one primary family caregivers of patients with CVAs at a general hospital in Seoul participated in this study . The patients with CVAs aged from 26 to 83 years with mean age of 63 years. About 90% of the patients had some paralysis and 56.6% suffered speech problems. Fifty-eight percent of the primary family caregivers were spouses of the patients and 80.2% were women. Primary family caregivers' burdens were assessed by the Burden Scale originally devel oped by Zarit (1980) and Novak & Geust(1989) and modified by Jang (1995) for use in Korea. The instrument consists of six subscales time-dependent burden, developmental burden, physical burden, emotional burden, social burden, and financiaI burden. The results were as follows : 1. The average of burden score was 91.7, indicating moderate to severe level of burden. The time-dependent burden was scored highest followed by physical, developmental, social, financial, and emotional burdens. 2. of the characteristics of patients, age, gender, and severity of the disease were found to be associated with the level of burden. Of the characteristics of primary family caregivers, age and educational level were significantly related to the level of burden. Time of care since the CVA and the quality of relationship between a patient and a caregiver prior to the stroke were significant situational factors affecting the level of burden. 3. The need for support group intervention for the caregivero was very high (95.1%). The earcgivcrs of patients who had a CVA for the first time showed higher levels of need compared to those of patients who had a CVA more than once. The caregivers indicated a support group held once a month near home or hospital would be welcomed. In addition, they replied that a group composed of 9 to 10 caregivers and guided by health care professionals (e.g., physicians and nurses) would be most desirable. More than 85% of the earegivers identified the areas that they wanted intervention in as follows : knowledge, skills, and resources to care for a patient with a CVA. the counsel of health care professionals, share of their experiences with those who have similar situations, stress management skills, and methods to overcome emotional isolation due to the great responsibility for a patient. Given the results, support group is expected to be an effective way to reduce the burdens of primary family caregivers of patients with CVAs. As a follow up It is necessary to examine the effect of support group intervention on the patient's recovery and rehabilitation.

Primary gallbladder carcinoma is generally assumed as uncommon but dismal malignancy. Only sporadic studies about pathologic features of the gallbladder carcinoma have drawn pathologists attention especially in association with cholelithiasis. Currently, we have focused much on the role of metaplastic changes in diseased gallbladders including cholecystitis with or without cholelithiasis, and raised its implication in the development of benign or malignant neoplasm. The authors reviewed 34 cholecystectomy cases with primary gallbladder carcinoma, and their histologic findings were analyzed with reference to the association of metaplastic changes both in tumor and adjacent nonneoplastic mucosal epithelium. Association with gallstones and metaplastic changes in the surrounding nontumorous mucosa is more frequent in intestinal typen than in non-intestinal type (P<0.05). Gallstones may play a role of irritant stimuli to the gallbladder mucosa which can be eventually reconstructed with more resistant cell type. And the subsequent increase in absorptive capacity and accumulation of carcinogenic substance may result in malignant transformation of (reserve) cells in replication zone. At this time we can assume that association of cholelithiasis and presence of metaplastic changes are in parallel relationshop in intestinal type adenocarcinoma. Intestinal type adenocarcinomas are usually papillary (72.7%) especially in superficial portion, but deeper area also shows infiltrative growth focally. This finding is comparable to intestinal type gastric carcinoma which represents frequently a polypoid and papillary growth pattern. With these results, as in the gastric carcinoma it is strongly supported that intestinal metaplasia may play a major role as a precancerous lesion in a minor group of the gallbladder adenocarcinoma. Controlled prospective study on biological behavior of intestinal type adenocarcinoma should be followed with more cumulative cases.

OBJECTIVE: To estimate the predictive value of initial serum B-hCG and progesterone measurement for pregnancy outcome in IVF-ET. METHODS: Serum B-hCG at 11-12th day after embryo transfer and progesterone at 7th day after oocyte aspiration were measured in 48 successful pregnant IVF-ET cases from July 1993 to June 1997. RESULTS: Of 48 cases, 26 cases (54.2%) successfully carried to sustaining gestation and 22 cases (45.8%) failed to sustain gestation. The estimated initial serum B-hCG levels in the normal sustaining pregnancy group (132.28+ 22.42 mlU/ml) were statistical significantly higher than 29.43+8.08 mIU/ml in the failed sustaining pregnancy group (p<0.001), while the estimated initial serum progesterone levels showed no significant differences (p=0.159). In order to determine the predictive values using the Receiver Operator Curve (ROC), an appropriate cutoff value of 38 mIU/ml for initial serum B-hCG was obtained. In IVF-ET pregnancies, the estimated serum B-hCG levels in cases of chemical abortion in failed sustaining pregnancy were significantly lower compared to the normal sustaining pregnancy group (p<0.001). CONCLUSION: The initial serum B-hCG levels at 11 days after embryo transfer could be used to predict the pregnancy outcome in an IVF program. An initial progesterone level acquired on the 7th day after oocyte retrieval is not a useful indicator to predict pregnancy outcome.
