An outbreak of dermatosis occurred in a livestock fodder factory at Kyongju in May 1994. Authors conducted a questionnaire survey on 60 workers in the factory and a dermatologist examined their skin lesion. Authors also collected mites and identified them. The obtained results were summarized as follows; 1. Twentyeight cases of dermatosis were identified with attack rate of 46.7%. Attack rate was not different by department, age, sex, educational level and employment duration. Attack rate was 67.5% in productive worker and 5.0% in clerical workers (p<0.01) but was not significantly different between departments among productive workers (p>0.05). 2. Three cases among 28 dermatosis cases and one subject among 32 non-cases had a history of same dermatosis last year. Only one of dermatosis cases had a history of dermatosis among family members. History of other skin lesion and allergy was very rare in both cases and non-cases. 3. Skin lesions of the cases were rice-sized erythematous papules or vesicles with a central biting point. Onset date of dermatosis was between May 1 and June 10. Duration was from one day to more than 30 days. Skin lesion was most frequent at the back(75.0%). and also observed at the arms(64.3%). abdomen(60.7%), legs(57.1%), chest(32.1%) and neck (25.0%). Skin lesion was aggravated while workers are sweeping the floor(35.7%), working at the workplace(21.4%) and in bed at night(28. 6%). 4. Total l,637 mites were collected and identified into 3 suborder, 7 families and 17 species. Dermafophagoides farinae was most frequent Nnd most of the species identified were blood sucking mites. Authors concluded that the outbreak of dermatosis was brought about by mite-bites and grain beetle parasitizing Acarophenax tribolii was the most suspected species. Further studies to identify the specific species causing dermatosis and route of import are needed.

PURPOSE: This study was aimed to identify research trends related to complementary and alternative therapy (CAT) in Korea. METHODS: Data were collected from 2000 to 2018 articles in Korean database (KISS, RISS and DBPIA). 295 semantic morphemes were extracted from 123 articles by network analysis program. Co-occurrence matrixes of the morphemes were generated by weighting Jaccard-coefficient and then we did network analysis and visualization. RESULTS: Common morphemes with high centralities were ‘Complementary and alternative medicine (CAM)’, ‘CAT’, ‘Aged’, ‘Diet therapy’, ‘Herbal medicine’, ‘Acupuncture’, and ‘Oriental medicine’. Since 2000, studies on complementary and alternative therapies have been actively involved in biological and manipulative therapies, and it has been found that the main target of CAT is the elderly. CONCLUSION: Despite much attention of complementary alternative therapies, the scientific basis is insufficient. Through this study, we could find research trends in complementary alternative therapies and set the direction of future research. It is necessary to expand research on complementary replacement therapy for various diseases and age groups.

Transcervical chorionic villus sampling (CVS) was performed in 174 patients between 7 & 12 menstrual weeks of pregnancy opting for prenatal diagnosis. Advanced maternal age was the most common indication for CVS (39.7%). The sampling success rate was 95.4% (166/174), representing 88.9% at 7 to 8 weeks, 98.9% at 9 to 10 weeks & 92.7% at 11 to 12 weeks gestation. In 139 of 174 patients (80%), successful sampling was accomplished in one or two catheter passages only. Four spontaneous fetal losses (2.3%) occurred. The cytogenetic analysis routinely used was the direct overnight & long-term culture methods which revealed 4 abnormalities (2.4%). To date, 90 of the women have been delivered & all infants are doing well and the remaining 65 pregnancies are continuing uneventually. Maternal serum alphafetoprotein (MSAFP) concentration was determined in 72 patients immediately before & after CVS. A significant increase of 20% or more, comparable to pre CVS levels, was noted immediately after sampling in 56 of 72 patients (77.8%). The increase in MSAFP concentration correlated with the amount of villi sampled (r = 0.498, p less than 0.001) & with the number of sampling attempts (p less than 0.05). Estimated CVS related fetomaternal hemorrhage (FMH) ranged from 0.005 to 0.1552 ml and in 5 of 72 patients (6.90%) 0.06 ml or more of FMH was noted. Two of the 5 patients had FMH of 0.1 ml or more.

Laparoscopic management is the ideal form of treatment for tubal pregnancy, most common type of ectopic pregnancy. Not only abdominal pregnancy including intraligamentary pregnancy is an rare form of ectopic pregnancy, but intraligamentary pregnancies are usually diagnosed and managed by emergency explorative laparotomy. We present the case of an intraligamentary pregnancy of a 28-year-old woman managed by laparoscopic treament without any complication.

BACKGROUND: Mucosa-associated lymphoid tissue(MALT) lymphoma has an indolent natural course. However, extra-gastric MALT lymphoma has been reported to have more frequent relapses and shorter time to progress than gastric MALT lymphoma. We performed this study to analyze clinical features of extra-gastric MALT lymphoma. METHODS: We retrospectively reviewed the medical records of the patients who were diagnosed as extra-gastric MALT lymphoma at the Samsung Medical Center from March 1995 to January 1999. The survival was analyzed by Kaplan-Meier method. RESULTS: During the study period, extra-gastric MALT lymphoma was diagnosed in 50 patients. The median age was 51(28-87)yaers. The male to female ratio was 22:28. Commonly involved sites were conjunctiva (25/50, 50%), lung (6/50, 12%) and intestine(6/50, 12%). Histopathologically, low to high grade ratio of extra-gastric MALT lymphoma was 47:3. Among 41 patients who were staged, 32 patients(78%) had stage I or II and 9 patients(22%)had stage IV. B symptoms were seen in only 3 patients. Bone marrow involvement was observed in 4 patients. The duration of median follow up was 22 months. The 1-year and 2-year survival rates were 95.1% and 91.4% retrospectively. CONCLUSION: Majoity of our cases with extra-gastric MALT lymphoma had low grade, early stage, good treatement reponse and good prognosis.

Continuous renal replacement therapy (CRRT) has been used increasingly for the management of renal failure in hemodynamically unstable and critically ill patients. CRRT requires anticoagulation, usually with heparin, to prevent clotting in the extracorporeal circuit. Systemic heparinization is associated with a high rate of bleeding when used during CRRT in critically ill patients. We applied regional citrate anticoagulation for CRRT to two critically ill patients with high bleeding risk using calcium containing commercial solutions. We conclude that regional citrate anticoagulation with commercial calcium containing solution can be used alternative to heparin for CRRT in patients with high bleeding risk.

OBJECTIVES: Area-based occupational disease surveillance in Kumi (KODS) was used to collect data on occupational diseases. The data was used to estimate the magnitude of the diseases, to analyze for their characteristics, and to find links for their intervention and prevention. METHODS: Since January 2001, occupational physicians and nurses in Occupational Health Service (OHS)have reported six major occupational diseases; occupational musculoskeletal disorders of the upper extremities(MSDUE), occupational dermatoses, toxic hepatitis, occupational asthma (OA), hand-arm vibration syndrome(HAVS), and occupational cancer. For the respective diseases, a reporting sheet and operational diagnostic criteria were developed by the KODS. An analysis of the KODS data, collected over a certain period, was compared with data from the Korea Labor Workers Corporation (KLWC) and the Specific Health Examination (SHE), and the incidence rates of the diseases estimated. RESULTS: Between Jan 2001 and Apr 2002, 287 cases of the six major occupational disease were reported. Of these, there were 132 (46.0%), 100 (34.8%), 34 (11.8%), 16 (5.6%), and 5 (1.7%), cases of MSDUE, occupational dermatoses, toxic hepatitis, OA, and HAVS, respectively. But, there were no cases of occupational cancer. 33 (11.5%) of the incidence were reported via the OHS, 206 (71.7%) from health checkups, and the other 48(16.8%) from other routes. The synthetic fibers and electronic components manufacturing industries accounted for the greatest number of reported cases. With respect to occupation, the greatest numbers of incidence were reported from the elementary occupations, textile workers, assemblers, and cooks and food services worker, in that order. Of the MSDUE cases, carpal tunnel syndrome and epicondylitis were the two most common diseases. Most of the occupational dermatoses were due to contact dermatitis, with organic solvents (59%), nickel (6%), and epoxy resin (5%) accounting for the majority of these cases. All cases of toxic hepatitis were induced by dimethylformamide or dimethylacetamide, which were reported by a unique monitoring system. During same period, there were no cases claimed by workers to the KLWC, and only three cases from SHE, were identified. Using data from workers' number and surveillance, the annual incidences of MSDUE, dermatoses, hepatitis, OA, and HAVS, per 100,000 workers were 63.6, 48.2, 17.9, 7.7, and 2.4, respectively. CONCLUSIONS: These results show that an area-based surveillance system can be very effective for the collection of data on work-related diseases, at least in Kumi.
