OBJECTIVE: Our purpose was to investigate the relationship between the levels of IL-6 and tumor necrosis factor-alpha in the peritoneal fluid of women with and without endometriosis and infertile women. METHODS: This study is prospective and case-control study in University hospital, enrolled thirty-four women with laparoscopic findings of minimal to severe endometriosis, and thirty-seven women with no visual evidence of pelvic endometriosis and with benign gynecologic disease. IL-6 and tumor necrosis factor-alpha levels in peritoneal fluid were determined using commercial ELISA. IL-6 and tumor necrosis factor-alpha concentrations were compared among women with and without endometriosis, and with infertile and fertile women, and then also compared according the revised American Fertility Society classification. RESULTS: IL-6 and tumor necrosis factor-alpha concentrations were higher than in the peritoneal fluid of women with endometriosis than in matched normal controls. Cyclic variations in IL-6 concentrations were seen in peritoneal fluid from patients with endometriosis: the concentrations in the secretory phase were significantly higher than those in the proliferative phase. The concentrations were higher than among of infertile women than in fertile women. A significant correlation between IL-6 and tumor necrosis factor-alpha concentrations and endometriosis stage III and IV was noted. CONCLUSION: Increased levels of IL-6 and tumor necrosis factor-alpha in patients with endometriosis in the peritoneal fluid may be relate to the pathogenesis of endometriosis suggesting that partially contribute to the disturbed immune regulation observed in patients with endometriosis.

Pain snd disability often fractures of the cslcaneus even though the original injury was skillfully treated. The causes are traumstic arthritis of the subtalar joint, abnormalities of the peroneal tendons or weakness of Gastrocnemius, etc. We have experienced the resection of lateral prominence of calcaneus in 7 patients who complained of pain by entrapment of peroneal tendons between lateral malleolus and lateral prominence of malunited calcaneus. The follow up time after operation was 3 years and 4 months to 12 months. In all patients the pain was markedly improved between postoperative 5 weeks and 10 weeks. When the last follow up, 6 patients among 7 patients except one case of subtalar arthritis were astisfaetory.

The morphologic abnormalities of the endocrine pancreas that underlie persistent neonatal hyperinsulinemic hypoglycemia and are included under the heading "nesidioblastosis" appears to be heterogeneous. This characteristic morphologic finding is ductuloinsular complexes showing endocrine cells budding off the ductoepithelium and merging with adjacent endocrine cell clusters. A case of nesidioblastosis associated with hyperinsulinemic hypoglycemia occurred in a 6/365 year-old male neonate. Microscopic finding of near totally resected pancreas revealed irregular sized islets and ductuloinsular complexes, both of which contained hypertrophied B cells with a few mitosis. Because of persistent hypoglycemia after first operation, he received second operation 8 days after. This histologic finding was more severe comparative to that of first operation. According to these findings, the pathogenesis of nesidioblastosis may be congenital or developmental defect of a kind of compensatory mechanism by unknown stimuli to acquire persistent hypoglycemia.

Soft tissue tumor is defined as a tumor occurring in voluntary muscles, fat, fibrous tissue, along with the vessels serving these tissue and peripheral nervous system. It is difficult to make a diagnosis by conventional microscopic observation because of their pleuripotentiality and similar growth characteristics. Although their morphological findings of tumors are similar to one another, their clinical courses, treatment and prognosis are different. So early, correct diagnosis and proper treatment are neccessary. The present study is aimed to evaluate a value of immunoperoxidase staining to make definite diagnosis of soft tissue tumors and its application to surgical pathology. The material consisted of 106 cases of fibrohistiocytic tumors and malignant soft tissue tumors which are morphologically similar to malignant fibrohistiocytic tumors for 5 years period lasting from 1980 to 1984 at the Department of Pathology, Yonsei University College of Medicine. After the classificationof fibrohistiocytic tumors by the Enzinger (1983), clinical finndings were reviewed and peroxidase antiperoxidase(PAP) method with alpha1-antichymotrypsin was done in 15 cases of all fibrohistiocytic tumors. Other soft tissue tumors which were difficult to differentiate from MFH by light microscopic observation were liposarcoma, rhabdomyosarcoma, fibrosarcoma and malignant schwannoma. These 21 cases of tumors including MFH were stained with PAP method for alpha1-antichymotrypsin, S-100 protein and myoglobin. Results obtained were as follows: 1) The cases on study consisted of 19 cases of malignant fibrous histiocytoma, 2 dermatofibrosarcoma protuberans, 45 fibrohistiocytic tumors and 11 other benign fibrohistiocytic tumors. 2) The male to female ratio was 1 : 1.8 in benign and intermediate group of fibrohistiocytic tumor, but 2.2 : 1 in malignant histiocytic tumor. 3) Most cases of benign fibrohistiocytic tumors were occurred in 4th and 5th decade of life. Intermediate and malignant fibrohistiocytic tumors were mostly found in late adult life and their mean age was 43.6 year. 4) The most common sites were trunk and both extrimities in benign fibrohistiocytic tumors(88.9%), but head, neck and lower extremities in MFH (78.9%). Two cases of dermatofibrosarcoma protuberans were occurred in turnk and upper extremity. 5) The PAP stain for alpha1-antichymotrypsin was done in 15 cases of 77 fibrohistiocytic tumors which included MFH, dermatofibrosarcoma protuberans, xanthoma, xanthofibroma, dermatofibroma showed variable degree of positivity to alpha1-antichymotrypsin. The positivity of alpha1-antichymotrypsin revealed no significant difference according to differentiation of the tumors, such as benign, intermediate and malignant. 6) The PAP stain for alpha1-antichymotrypsin revealed diffuse positivity in all cases of MFH and also in a case of malignant schwannoma, fibrosarcoma, liposarcoma and rhabdomyosarcoma, but myoglobin and S-100 protein were negative. In three cases of leiomyosarcoma, two of rhabdomyosarcoma and three of malignant schwannoma, alpha1-antichymotrypsin, S-100 protein and myoglobin were negative, although a few positive tumor cells were present, which may the considered as metatypci differentiation. Another possibility of this discordance was loss of antigenicity by improper procedure of paraffin embedding and poor differentiation of tumor cells. In summary, PAP method for specific tumor marker is important for proper diagnosis of soft tissue tumors, and application to surgical pathology.

OBJECTIVE: Our purpose was to investigate the relationship between the levels of IL-6 and tumor necrosis factor-alpha in the peritoneal fluid(PF) of women with and without endometriosis and infertile women. Design: Prospective and case-control study. Setting: University hospital. Patients: Twenty-nine women with laparotomy or laparoscopic findings of minimal to severe endometriosis, and twenty-eight women with no visual evidence of pelvic endometriosis and with benign gynecologic disease. Main Outcome Measures: PF IL-6 and tumor necrosis factor-alpha levels were determined using commercial ELISA. IL-6 and tumor necrosis factor-alpha concentrations were compared among women with and without endometriosis, and with infertile and fertile women, and then also compared according the revised American Fertility Society classification. RESULTS: IL-6 and tumor necrosis factor-alpha concentrations were higher than in the PF of women with endometriosis than in matched normal controls. Cyclic variations in IL-6 concentrations were seen in PF from patients with endometriosis: the concentrations in the secretory phase were significantly higher than those in the proliferative phase. IL-6 concentrations were higher than in the PF among of infertile women than in fertile women. A significant correlation between PF IL-6 and tumor necrosis factor-alpha concentrations and endometriosis stage III and IV was noted. CONCLUSIONS: Increased PF levels of IL-6 and tumor necrosis factor-alpha in patients with endometriosis may be relate to endometriosis-associated infertility and to the pathogenesis of endometriosis suggesting that partially contribute to the disturbed immune regulation observed in patients with endometriosis.

OBJECTIVE: Endometriosis is a disease affecting a large population of women all over the world. A local sterile inflammation occurs in the peritonel cavity of patients with endometriosis. It suggests that immunological events play a major role in the pathogenesis of endometriosis. We have studied the levels of serveral T cell and monocyte derived cytokines, especially IL-6 (promoter of immune response) and IL-10 (inhibitor of immune response), in the peritoneal fluid of patients with endometriosis to characterize the change of immune response that occurs at the site of endometriosis. Method: This study was performed in Hallym university hospital from October, 1997 to October 1998 and enrolled 29 women with gross or microscopic findings of minimal to severe endometriosis in case group, and 28 women without visual evidence of pelvic endometriosis and with benign gynecologic disease in control group. IL-6 and IL-10 levels in the peritoneal fluid were determined using commercial ELISA and compared between endometriosis and controls and between fertile and infertile women with endometriosis and according to the revised American Fertility Society classification. RESULT: IL-6 was higher and IL-10 was lower in the peritoneal fluid of endometriosis group than of control group. Cyclic variations in the IL-6 concentrations were seen in endometriosis group : the concentrations in the secretory phase were significantly higher than those in the proliferative phase. In endometriosis group, IL-6 concentrations of infertile women were higher than fertile women. Both IL-6 and IL-10 in the peritoneal fluid of endomtriosis group did not show significant correlation according to r-AFS stages. CONCLUSION: Increased IL-6 and decreased IL-10 levels in the peritoneal fluid may be related to infertility and pathogenesis in the endometriosis, suggesting that partially contribute to the disturbed immune regulation observed in endometriosis.
