BACKGROUND: Allergic diseases are characterized by immediate - and late - phase reactions to various allergens by the selective activation of a subset of CD4 + T cells. In response to allergen, T cells isolated from atopic donors are biased to low levels of IFN - y and high levels of IL - 4, and vice versa by T cells from non - atopic donor. Objective : The aim of this study was to evaluate the patterns of IL - 4 and IFN - y production after Der p I stimulation and the effect on the cytokine production from T cells by budesonide, disodium cromoglycate and cyclosporin A in atopic and non - atopic individuals. MATERIAL AND METHOD: Seven Der p I specific atopic and 7 non - atopic individuals were selected. We decided the 50% inhibiting concentration of each immunomodulator by lymphocyte proliferation assay, and measured their effects on the cytokine production in vitro by intracellular IL - 4, IFN - y staining and flow cytometry. Results and CONCLUSION: There was significant difference on stimulation index ( SI ) of production of IFN - y as well as IL-4 after Der p I stimulation between atopic and non-atopic individuals ( IL - 4 ; 1.57 +/- 0.7 : 0.98 +/- 0.2, p = 0.026, IFN - r : 1.45 +/- 0.5 : 0.95 +/- 0.2, p = 0.048 ). The synthesis of IL - 4, and IFN - r were significantly inhibited after the stimulation of every immunomodulators in atopic individuals, DSCG couldnt inhibit IL - 4 and IFN - r in nonatopic individuals. There was no significant difference in the inhibiting effect of these immunomodulators in both of them.

Fractures of the shaft of the radius and ulna occur commonly in children and are usually treated by closed reduction and plaster cast immobilization. Anatomic reduction is seldom necessary because of the remodelling potential in the child under 10 years of age, whereas the bones of children older than 10 years of age have less capacity to remodel and the diaphyseal fracture is unstable. In case of either unacceptable reduction or unstable fractures in adolescent patients, an operative treatment is required. In five children older than 12 years of age for whom conservative treatment had hailed, we treated a closed intramedullary nailing using a distal radial and proximal ulnar approach, and followed up for 1 year or more. All fractures healed within 6 weeks. No nonunion, cross-union or refrature occured. Another advantages of this method are negliable cosmestic defect and easy removal of the internal fixation device under local anesthesia. We think that closed intramedullary nailing with rush pin is a safe and reliable method to treat unstable forearm fracture in children older than 12 years of age.

Palisaded encapsulated neuroma (PEN) is a distinctive benign cutaneous tumor that was first described by Reed et al. in 1972. We have recently experienced two cases of PEN. Clinically, these lesions were asymptomatic, flesh-colored or reddish brown papules or nodules. Light microscopy revealed several lobulated, partially encapsulated dermal tumors composed of interlacing Schwann cell fascicles. In some areas, palisading of nuclei was observed, but this was not characteristic. On Bodian staining, moderate to large numbers of tiny axons were observed. Electron microscopy demonstrated many myelinated axons incompletely invested by Schwan cell cytoplasm.

Small cell carcinoma of the ovary has been identified as a specific histopathologic entity. The first II cases were reported by Dickersin et a1, 1982, Since then only 80 cases were reported in literature. This rare and highly aggresive melignancy primarily affeets ehildren and young women(10-40) and grows rapidly, with hypercalcemia occuring frequently. Abscence of effective treatment results in early mortality. Recently we have experienced one case of primary sma11 cell carcinoma of the ovary, which is presented with a brief review of the literature.

Treatment of pelvic malignancy persistent or recurrent after surgery, radiation therapy or chemot-herapy presents a difficult therayeutie challenge. Those patients with central recurrence can be considered as candidate for radical resection. However we must consider many factors for the choice of treatment modality for advanced or recurrent pelvic rnalignancy as follows; the size and location of the recurrent cancer, dose of radiation therapy given, general conditions of the patient and the experience of the surgeon. Pelvie exenteration, when appropriate, is suecessful treatment for recurrent or persistent pelvic malignancy; 5-year survivai has been reported to be as high as 50%. We experienced seven cases of pelvic exepteration for pelvic malignancy between Mar. 1990 and Feb. 1993, Accordingly we present the cases with a brief review of the literatures.

BACKGROUND AND OBJECTIVES: The frontal recess (FR) cells, including the frontal cell (FC), agger nasi cell (ANC), supraorbital ethmoid cell (SOC) and inter-frontal sinus septal cell (IFSSC), can interfere with the drainage system of the frontal sinus. We evaluated the relationship between the FR cells and the frontal sinusitis. SUBJECTS AND METHODS: All paranasal sinus CT scans performed from July 2004 through June 2005 were reviewed. Of the 675 scans reviewed, 317 patients (634 sides) were selected for data collection. Exclusion criteria included a clinical history of neoplasms, bony deformities, and extensive disease responsible for obscuring the bony anatomy. Similarly, CT scans with severe artifacts were also excluded. RESULT: FCs were present in 21.9% of the patients. According to the Bent's classification, the prevalence of each FC type was as follows; type 1 FC (13.6%), type 2 FC (3.2%), type 3 FC (1.9%) and type 4 FC (3.1%). Of the four types of FR cells, type 4 had a significant association with frontal sinusitis. The incidence of hyperpneumatized frontal sinus, ANC, SOC, IFSSC were significantly higher among patients with the FC than those without the FC (p<0.05). Patients without the ANC or with type 1 uncinate process, according to Stammberger's classification, displayed a higher frequency of frontal sinusitis (p<0.05). There was a statistically significant decrease in the frequency of frontal sinusitis among patients with hypopneumatized frontal sinus (p<0.05). CONCLUSION: In our series, the frontal sinusitis was influenced by each types of FC, attachment sites of uncinate process and the degree of frontal sinus pneumatization. Therefore, these anatomic variations in the frontal recess should be appropriately addressed during the surgical management of the frontal sinusitis.
