PURPOSE: Headache is a frequent symptom in pediatric practice, but the prevalence of chronic recurrent headache was estimated in several studies with wide variations, because of inadequate expression and differences in case definition in children. Headache classification of International Headache Society is usually used in adults, but the application of it to children is uncommon, so we tried to diagnosis children with headache by using International Headache Society Classification. METHODS: We analyzed the clinical pictures, physical examinations including neurologic examination, PNS series, EEG and CT or MRI in 53 children with nonprogressing recurrent headache over than one month, who visited to pediatric department of Dong-A University hospital from January, 1995 to Feburary, 1996 and diagnosed them by using International Headache Society Classification. RESULTS: 1) The sex ratio between male and female was 1:1.2. 2) Diagnosed groups consisted of children with migraines in 22 cases(41.5%), tension-type headache in 19 cases(35.9%), coexisting migraine and tension-type headaches in 5 cases(9.4%), miscellaneous headaches not associated with structual lesion in 1 case(1.9%), headache associated with vascular disorders in 2 cases(3.8%), headache associated with nonvascular intracranial disorder in 1 case(1.9%), headache due to facial pain in 3 cases(5.6%). 3) Of 22 migraine cases, 13 cases(59.1%) had migraine with aura, 8 cases(40.9%) have migraine without aura and of 19 tension-type headache cases, 8 cases(42.1%) have episodic type, 11(57.9%) cases have chronic type. 4) Of 53 cases with recurrent headache, 3 cases(6%) had abnormal findings in CT or MRI. 5) Of 53 cases with recurrent headache, 9 cases(17%) had abnormal findings in EEG. CONCLUSIONS: International Headache Society Classifications are useful, but the diagnostic criteria are too strict for children, especially in migraine and tension type headache.

We report a rare case of carcinosarcoma arising in the stomach. The tumor is presented in the posterior wall of the gastric lower body and antrum of a 56-year-old man. Grossly the tumor has polypoid appearance with diffuse surface ulceration and measures 5.5 cm in diameter. The tumor is accompanied with three separate well differentiated early gastric adenocarcinomas (two EGC type IIc & IIa). Microscopically, the tumor consists of moderately well differentiated adenocarcinoma in the periphery, and lobulated sarcomatous areas in the center, which shows chondroid differentiation. Transitional areas between adenocarcinoma and chondrosarcoma are evident. Immunohistochemical studies show positivity for cytokeratin and carcinoembryonic antigen in the epithelial component, and for vimentin and S-100 in the sarcomatous component. The transitional areas are positive in carcinoembryonic antigen, vimentin, S-100, and cytokeratin. The tumor extended to the subserosa and showed metastasis of only adenocarcinomatous component in six out of 47 dissected perigastric lymph nodes.

Background: Inter1eukin-6(IL-6) is known to be produced by osteoblastic cells and to have impartant role in regulation of bone remodelling, Most previous studies indicated that IL-6 bas a major role in stimulating osteoclastic resorption by increasing recruitment and proliferation of preosteoclasts. But its autocrine effect on osteoblastic cells has not been well established yet. Therefore, we studied the effects of IL-6 on messenger RNA (mRNA) expression of proteins that are characteristic of osteoblastic cells in human bone marrow stromal (osteoprogenitor) cells (hRMSC). Methods: The expression of mRNAs for alkaline phosphatase, al(1)-collagen, osteopontin and decorin were studied by northern blot analysis after 3 7 days' treatrnent with IL-6 in the concenttation range of 101,000 U/ml. Results: The mRNA levels for any of the osteoblastic proteins studied did not change significantly by IL-6 treatment up to the concentration of 1,000 U/ml. Conclusion: These results suggest that IL-6 does not have a significant role in differentiatian or activities of human bone rnarrow stromal.
