From January 1995 to December 1997, a total of 219 cases pelviscopic surgery was performed at Il Sin Christian Hospital. To evaluate the safty and efficacy of pelviscopic surgery, we reviewed indication of operation, mean age, parity, history of abdominal operation, type of operation, duration of hospitalization and complication retrospectively. The number of pelviscopic surgery have risen from 33 cases in 1995 to 53 cases in 1996 and 133 cases in 1997. The most common indications were 118 cases for ectopic pregnancy (53.9%) and 42 cases for ovarian cyst (19.2%), 20 cases for infertility (9.1%) in order. Among the ovarian cyst, endometrioma was the most common. The mean age of patients was 31+/-6.7 years old and mean parity was 0.77. In most cases, mean blood loss was lesser than 100 cc except 500 cc in LAVH, 150 cc in CISH, 106.7 cc in ectopic mass removal. The postoperative hospital stay was varied from 0 day to 10 days, but usually 2 days. The 26 cases had complicated and the most common complication was fever above 38degrees C. In conclusion, it is evident that pelviscopic surgery is lesser invasive technique, has lower complication rate and shorter the length of hospitalization. So, we expect the number and indication of pelviscopic surgery will be increased in future.

PURPOSE: Lymphoma is considered when multiple, nonnecrotic lymph nodes are present in the superficial and deep lymphatic chains, especially if they are large and bilateral, on CT scan. It is reported that combined nodal and extranodal presentation of HD is uncommon. However, we found central low density in involved lymph node of NHL, and combined nodal and extranodal disease in HD, not infrequently. The purpose of this study is to ascertain whether our findings may be characteristics of NHL and HD. MATERIALS AND METHODS: CT findings with contrast enhancement were reviewed in 23 patients with untreated neck lymphoma:18 NHL and 5 HD. The followings were analyzed in each case: nodal or extranodal involvement; unilateral or bilateral involvement; presence or absence of central low density with peripheral enhancement in nodal lesion ;infiltration into adjacent structures. Nodal and extranodal lesions were confirmed by pathologic studies. RESULTS: Of 18 patients with NHL, nine cases had nodal disease and the rest had combined nodal and extranodal disease. Lymphadenopathy was bilateral in ten cases and unilateral in eight. Five cases with HD were composed of three combined nodal and extranodal diseases and two nodal diseases. Central low density of involved lymph node was shown in eight cases of 18 NHL and in one case of five HD. CONCLUSION: Central low density with peripheral enhancement was not uncommon in NHL, in contrast to HD. Hence, it is suggested that in case of nodal necrosis, NHL be also considered, besides tuberculous lymphadenitis and metastatic lymphadenopathy. It is not considered that nodal or extranodal disease, and unilateral or bilateral involvement are of high significance in differentiation of NHL from HD.

BACKGROUND: To prevent the platelet refractoriness, repeated plateletpheresis is often required in HLA matched single-donors. Korean Transfusion Standard permits the repeated plateletpheresis of a single donor at 72-hour intervals. To evaluate this standard, hematological responses of donors were assessed after plateletpheresis by Haemonetics V50 (Haemonetics Co., USA). METHODS: The pre- and post-donated hematological indices of 22 healthy donors(17 males and 5 females) were evaluated. Single donated donors were 12 males and 4 females. Multiple donated donors were 5 males and one female. Post-donated platelet counts were measured immediately, 6 hours, 12 hours, 1 day, 3 days, 5 days, 7 days and 9 days after plateletpheresis. Platelet aggregation test, serum protein, PT, and aPTT were also examined before and after platelet collection. RESULTS: Only 9 (56.2%) of 16 single-donated donors and 4 (66.7%) of 6 multiple donated donors showed normal restoration up to 97% of platelet counts of pre-donation levels at the day 3. In 9 (75%) of 12 single donated males restoration of platelet count was observed within 3 days, but 3 (75%) of 4 single donated females showed restoration of platelet count within 5 days. Changes of other indices were not significantly different between the pre- and post-donations of platelet. CONCLUSIONS: Although no clinical complication was noted after plateletpheresis, these data suggested that Korean Transfusion Standard on plateletpheresis should be reconsidered.

BACKGROUND: The purpose of this study was to identify risk factors for low back pain in order to provide basic information for intervention programs to prevent low back pain in civil airline flight attendants. METHODS: Cross sectional observation was used by using systematic randomized sampling method. Among 1,764 study population, 398 people were selected. For statistical analysis, 210 completed questionnaires were used. Data was analyzed using SPSS 11.0 for t-test, chi square and regression. RESULTS: 1. Positive low back pain rate was 58.7% in the whole study group. In the highest positive group age ranged between 25 to 29 years, and career duration between 37 to 60 months. 2. According to job position, the risk of low back pain was the highest in economy class senior, cabin sales charge, and economy class junior group. On the contrary, cabin manager was the lowest risk group. 3. According to the average score of job stress, low job control and low supervisory support were each associated with higher positive rate of low back pain. 4. Wide degree of bending, more frequent waist movement and heavy lifting showed high positive rate of low back pain. CONCLUSION: Low back pain prevention program should be developed on the basis of the confirmed risk factors. These data will be helpful to provide prevention strategy and to promote intervention program for low back pain in airline flight attendants.

Peripheral T-cell lymphoma is the generic group given to a family of tumors composed of neoplastic lymphocytes with phenotypic features of peripheral T-cells. Certain peripheral T-cell lymphomas develop a hemophagocytic syndrome that mimics malignant histiocytosis, both clinically and pathologically. We experienced a case of nasal T-cell lymphoma, histologically mimicking malignant histiocytosis in a 40-year-old male. The chief complaints were nasal obstruction and intermittent mild fever. Mild anemia, elevated SGOT and SGPT, polyclonal gammophthy, and moderate hepatomegaly were present. Two weeks later was present an enlarged cervical lymph node. The biopsied nasal mass showed angiocentric and angiodestructive peripheral T-cell lymphoma withextensive necrosis and marked erythrophagocytosis by non-neoplastic histiocytes. Subsequently, cervical lymph node was biopsied, which showed peripheral T-cell ltmphoma with extensive necrosis and erythrophagocytosis as well. The atypical lymphoid cells revealed pan-T(+), but CD4(-) and CD8(-), whereas the reactive histiocytes showed lysozyme(+), immunohistochemistry.

Rosai-Dorfman disease (RDD) is a rare type of benign histiocytosis characterized histologically by intracellular engulfment of lymphocytes. Extranodal RDD may occur as a part of generalized process involving lymph nodes or may involve extranodal sites independent of the lymph node status. We have experienced a case of extranodal Rosai-Dorfman disease of the nose as an initial lesion prior to nodal involvement. The patient was a 20-year-old woman who complained of nasal obstruction for 4 years, remotely, and left submandibular mass for 3 months, recently. Histologically, the lesion taken from nasal cavity, submandibular gland and left upper jugular lymph node all showed an heavy infiltrate consisted of plasma cells, lymphocytes and sheets of macrophages with abundant pale cytoplasm, which replaced organ architecture. The associated focal fibrosis made it difficult to differentiate from inflammatory pseudotumor. Some macrophages demonstrated phagocytosis of lymphocytes, plasma cells and occasionally neutrophils. The macrophages were strongly positive for S-100 protein.
