This survey was conducted to investigate Farmers' Syndrome and its related factors in Chonnam province. 5,920(men 6,148, women 6,722) persons in urban area and 12,870(men 6148, women 6,722) persons in rural area were selected in stratified cluster sampling manner, and interviewed individually with structured questionnaire in April, 1992. The results were summarized as follows: 1. In rural area of Chonnam province, the prevalence of Farmers' syndrome positive was 283 per 1,000 persons(203 in male, 355 in female). In urban area of Chonnam province, control area, the prevalence of Farmers' syndrome positive was 113(72 in male, 145 in female). The prevalence of Farmers' syndrome positive in rural area was 2.5 times higher that of urban area, and the prevalence in female was 1.7 times higher than that of male. The prevalence in total respondents was 256. 2. In rural area of Chonnam province, the age standardized prevalence of Farmers' syndrome positive was 209 per 1,000 persons(140 in male, 267 in female). In urban area of Chonnam province, control area, the age standardized prevalence of Farmers' syndrome positive was 122(79 in male, 158 in female). The age standardized prevalence in total respondents was 194. 3. The associated factors with Farmers' syndrome in univariate analysis were having illness during recent 15 days ,age, sex, occupation, area, monthly income, education, medical security status, family size and duration of farming. 4. When applying multiple logistic regression for Farmers' syndrome, the significant variables were having illness during recent 15 days, area, sex, age, education, medical security status, family size and duration of farming.

Ovarian Pregnacy is a rare form of ectopic pregnacy. Its estimated overall incidence is highly variable, but improved diagnosis of acute hemoperitoneum of ovarian pregnancy may reveal a high incidence than reported earlier. Ovarian pregnancy occurs in the corpus luteum, and is usually accompanied with the rupture of the ovary and massive hemoperitoneum. It presents as a hemorragic ovary and frequently misdiagnosed as a ruptured corpus luteum. Risk facters to ovarian pregnacy include a history of pelvic inflammatory disease(PID), prior pelvic surgery, and use of an intrauterine contraceptive device(IUD). We have experienced two cases of ovarian pregnancy and reviewed it briefly.

BACKGROUND/AIMS: To compare treatment outcome of hepatocellular carcinoma(HCC) under the size of 5 cm in relation to underlying liver function and treatment modalities, analysis of data from 145 patients was performed. METHODS: In this study, the records of 145 patients with small HCC (< 5 cm in diameter determined by hepatic angiography) were reviewed. Clinical parameters were analyzed and survival rate, recurrence rate were calculated. RESULTS: There were 107(73.8%) men and 38 women. Mean age at diagnosis was 55.1(range .' 25 83 year-old). HBsAg was detected in 97(66.9%) patients. Seventy two(50.0%) patients showed markedly elevated(>40 ng/mL) serum alpha-fetoprotein(AFP) level. Liver cirrhosis was associated in 109(75.2%) patients. Sixty five(44.8%) patients underwent surge, 63(43.5%) underwent transarterial therapy(TAT), 8(5.5%) underwent other modalities of therapy and the remaining 9(6.2% ) patients did not receive any specific treatment for HCC. In relation to the underlying liver function, 119(82.1% ) patients belonged to the non-cirrhotic or Child-Pugh class A, 20(13.8%) to class B and 6(4.1%) to class C. The median follow-up duration was 21 months. When analyzed with respect to treatment modalities alone, median survival was 43 months for all patients, 60 months for surgery, 29 months for TAT, 20 months for other treatment and 18 months for patients who received no specific treatment. Without considering liver function, cumulative 3 year survival rate was 68.6% for surgery, 43.9% for TAT, 29.2% for other treatment and 0% for no treatment. The survival rate for the patients who underwent surgery was significantly higher than for any other treatment modalities without considering the underlying liver function or in the non-cirrhotic/Child-Pugh class A(p<0.001). In patients whose tumor size was equal to or less than 3 cm, there was no difference in survival rate in relation to the treatment modalities when not considering the underlying liver function of each patient(p>0.05). But in patients classified as the non-cirrhotic/Child-Pugh class A, better survival was observed in the surgep group than the TAT group(p<0.05). The only factor influencing survival was the pre-treatment serum AFP level(p<0.05). The overall recurrence rate was 30.3%. For the entire patients, the factor significantly influencing the recurrence rate was the presence of underlying cirrhosis. When considering only the patients in the surgery group, the different types of surgical procedures significantly influenced the recurrence rate. CONCLUSION: Surgery is the treatment of choice for patients with HCC equal to or smaller than 5 cm. But for those patients whose tumor size is less than 3 cm, TAT may be a reasonable alternative to surgep when the liver function is not adequate for hepatic resection. Because overall recurrence rate exceeded 30% and median time of recurrence was only 9.5 months after definitive treatment, careful follow-up is required for all patients who undergo treatment for small HCC.

We investigated the feasibility of the extracorporeal suture technique in laparoscopic pyeloplasty and laparoscopic ipsilateral ureteroureterostomy in child with ureteropelvic junction obstruction or duplex kidney. Laparoscopic pyeloplasty and laparoscopic ureteroureterostomy were performed in a child with ureteropelvic junction obstruction and in a 3-year old child with duplex kidney, respectively. Ureteropelvic junction or ureters were dissected laparoscopically and were drawn out of the abdominal cavity through the 10mm trocar tracts and subsequently anastomosed extracorporeally. We were able to draw the ureteropelvic junction or the ureters out of the abdominal cavity without difficulty owing to the laxity and thin abdominal wall in children. Operating time was 120 minutes in both cases, and all anastomses between ureter and pelvis were completed without any intraoperative complication. There was no postoperative complication. Significant improvements in urinary drainage were shown in both children on postoperative intravenous pyelogram. These early results suggest that the extracorporeal suture technique in children is feasible and easy to perform. Therefore, the drawbacks of intracorporeal suture technique during the laparoscopic pyeloplasy or ureteroureterostomy could be overcome by using this novel teehnique.

In order to demonstrate autoradiographically the sites of serotonin metabolism in the brain, DL 5-HTP and DL 5-HTP-C14 were intraperitoneally administered to healthy adult mice. In order to distinguish histochemically serotonin-like substances which have staining characteristics similar to the enterochromaffin cells of the gastrointestinal tract, serotonin-releaser reserpine was administered intravenously to healthy adult rabbits. A stripping film technique for autoradiography, a ferric ferricyanide reduction test by Schmorl, and a Gomori-Burtner methenamine silver staining method for argentaffin cells were used in this study. In the brain tissues of mice treated with 5-HTP, it was observed that the cytoplasm of the nerve cells, of the cerebral cortex had blue positive staining substances by the ferric ferricyanide technique. In similar tissue sites in mice treated with 5-HTP-C14, a number of blackened-par-ticles reduced by beta rays were easily found. especially in the cytoplasm of nerve cells and neuroglia cells. It is suggested that the serotonin precursor, DL 5-hydrox-ytryptophan is metabolized the cerebral tissue, and serotonin is synthesized also in the nerve cells and the neuroglia cells.

OBJECTIVE: The purpose of this study is to characterize the distribution of posterior inferior cerebellar artery (PICA) aneurysm, the computed tomography (CT) patterns of hemorrhage, and the clinical presentation thereof. METHODS: We reviewed the records 1050 patients with intracranial aneurysms treated at our institution between January 1999 and November 2003. Upon clinical review of radiological data and postoperative reports, we found 20 patients with PICA aneurysms. RESULTS: The incidence of PICA aneurysms was 1.9% of all intracranial aneurysms. The location of PICA aneurysms varied. Of the 20 PICA aneurysm cases, ruptured aneurysms accounted for 18 cases. Review of only these ruptured cases resulted in the following observations : Subarachnoid hemorrhage (SAH) was presented in 94.4% of cases. Isolated infratentorial and supratentorial SAH was present in 7 cases (38.9%) and 2 cases (11.1%), respectively. SAH involving the infratentorial and supratentorial region was present in 8 cases (44.5%). Intraventricular hemorrhage (IVH) with or without associated SAH was seen in 77.8% of cases, whereas isolated IVH was seen in only one case. Perimedullary large hematoma was present in 50% of cases, while the hematoma was consistently thicker on the aneurysm side. Hydrochephalus was present in 16 cases (88.9%). Although patients' postoperative outcomes were excellent or good in 70% of the above cases, initial angiograms failed to reveal ruptured PICA aneurysms in 3 cases. CONCLUSION: PICA aneurysm is rare in most aneurysm cases. However, awareness of a possibility of PICA aneurysm and its features are still nonetheless important. IVH and hydrocephalus are commonly presented with a ruptured PICA aneurysm and complete vertebral angiography is a required to recognize this condition.

Henoch-Shonlein(H-S) purpura, or anaphylactoid purpura is a hypersensitivity vasculitis characterized by palpable purpura usually on buttock and low extremities; arthralgia mostly polyarhtralgia in the absence of frank arthritis; gastraintestinal involvement with colicky abdominal pain, nausea, vomiting, diarrhea, constipation and bleeding; and renal involvement, manifested chiefly by hematuria and proteinuria. Gastrointestinal involvement is seen in 70 percent of pediatric patients and one third of adult patients. Any portion of the gastrointestinal tract distal to the esophagus maybe involved, but most frequently affected sites are jejunum and ileum. We report one case of H-S purpura with duodenal involvement observed in 16, male patient.

A case of Mycobacterium avium arthritis in a 39-year-old female patient with mixed connective tissue disease (MCTD) was reported. An extra-articular abscess had formed outside the knee joint and extended down the calf. A culture was taken of the abscess and synovial fluid disclosed Mycobacteriun avium. This was resistant to most anti-tuberculosis agents. A combination of anti-tuberculosis drugs followed a total resection of the abscess. We concluded that M avium septic arthritis could insidiously develop into an extra-articular abscess. A combination of anti-tuberculosis drugs with a total resection of the abscess was an effective treatment.

Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) with uncertain etiopathogenesis. CD can involve any site of gastrointestinal tract from the mouth to anus and is associated with serious complications such as bowel strictures, perforations, and fistula formation. The incidence and prevalence rates of CD in Korea are still lower than those of Western countries, but have been rapidly increasing during the past decades. Although there are no definitive curative modalities for CD, various medical and surgical therapies are currently applied for diverse clinical situations of CD. However, a lot of decisions on the management of CD are made depending on the personal experiences and personal dicision of physicians. To suggest preferable approaches to diverse problems of CD and to minimize the variations according to physicians, guidelines for the management of CD are needed. Therefore, IBD Study Group of the Korean Association for the Study of the Intestinal Diseases has set out to develop the guidelines for the management of CD in Korea. These guidelines were developed using the adaptation methods and encompass the treatment of inflammatory disease, stricturing disease, and penetrating disease. The guidelines also cover the indication of surgery, prevention of recurrence after surgery, and CD in pregnancy and lactation. These are the first Korean guidelines for the management of CD and the update with further scientific data and evidences is needed.
