OBJECTIVES: Nasal continuous positive airway pressure (nCPAP) is the treatment of choice and has been shown to reduce the frequency of nocturnal respiratory events, improve sleep architecture, and decrease daytime sleepiness in patients with obstructive sleep apnea syndrome (OSAS). However, little is known about the compliance of nCPAP treatment in Korea. Our objective was to look into the nCPAP compliance and examine the factors influencing it. METHODS: We reviewed the records of one hundred and twenty consecutive patients with OSAS referred for nocturnal polysomnography with nCPAP pressure titration during the period of January 1995 through April 1999 to the Seoul National University Hospital. We performed a telephone interview and obtained data from eighty-three patients. RESULTS: In sixty patients who had accepted nCPAP treatment, twenty-six patients (43.3%) were still using nCPAP device, while thirty-four patients (56.7%) stopped using it. Fifteen patients (25%) were using nCPAP device everyday. In thirty-four patients who discontinued nCPAP use, twenty-five patients (73.5%) did within the first three months, and thirty-one (91.2%) within the first year. Significant predictor of long-term nCPAP use was the presence of subjective daytime sleepiness before nCPAP application. CONCLUSIONS: Long-term compliance with nCPAP treatment appears to be associated with the presence of subjective daytime sleepiness before nCPAP application. Long-term compliance with nCPAP may be mostly predicted from the usage pattern within the first three months of use.

PURPOSE: To evaluate the prognostic significances of angiogenesis and bc1-2, and association of each other, we investigated the correlation of microvessel count for angiogenesis and bcl-2 expression in breast cancer. MATERIALS AND METHODS: We analysed immunohistochemistry staining from paraffin blocks in a series of 145 women with breast cancer. Immunohistochemical staining to detect factor VIII-related antigen highlighted the microvessels within primary invasive breast carcinoma. Using light microscopy, we counted microvessels per 200X field in the most active areas of neovascularization. To determine the bcl-2 immunoreactivity, we used a monoclonal antibody directed against the bcl-2 protein. RESULTS: The median of microvessel count (MVC) was 31.5, and the proportions of tumors with low and high MVC were 51% and 49%. Eighty (55.2%) cancers showed the bcl-2 immunoreactivity in the cytoplasm. The microvessel count were correlated with lymph node status (p <0.001), tumor size (p=0.001), and lymphatic invasion around tumor (p=0.009). bcl-2 expressions were corelated with estrogen receptor positivity (p<0.001) and progesterone recepter positivity (p=0.029). The microvessel counts were negatively correlated with bcl-2 expression (p=0.006). CONCLUSION: This study suggest that the angiogenesis which was investigated by micro- vessel counts was negatively correlated with bcl-2 expression.

Telescopic denture has freedom in the positioning of abutments, ease of repair for abutment loss, and a simple structure. In this case, the patient initially treated with fixed prosthesis, but had to remove some implants due to diabetes. Given the number and location of remaining teeth and implants, the possibility of further tooth loss, and ease of cleansing, a decision was made to fabricate a telescopic denture. The telescopic copings were made with zirconia for aesthetic appearance. In patients with uncertain prognosis of additional implant placement, converting to a telescopic denture can provide successful outcome aesthetically and functionally.
