Soft denture liners or conditioners may be valuable therapeutic materials. The life of these liners is short and varies, but it can be extended by the use of a mono-poly(polymethyl methacrylate coating material). This study determined whether coating three temporary soft denture liners with mono-poly affected the resiliency of soft liners, and evaluated the ability of mono-poly to prevent water absorption and alcohol loss from the underlying soft liners. 20x12mm cylindrical specimens of Coe-Soft, Soft-Liner, Coe-Comfort soft lining materials were made and divided into two groups of mono-poly uncoated(control) and mono-poly coated specimens. Specimens were immersed in water and compressed on an instron universal testing machine and weighted at initial, 24 hours, 1 week, 2 weeks, and 4 weeks. resiliency was determined by measuring the energy absorbed by the soft liners when stressed to a specific yield point. Mono-poly coating significantly increased the resiliency of the Soft-Liner, but had no effect on the other soft liners. Among the 3 soft liners, Soft-Liner showed the hightest resiliency and modulus of elasticity. The weight loss in Soft-Liner was the least among the 3 liners, and the weight loss in Coe-Soft was decreased by monopoly coating.

The retinoic acid and retinoid(Ro 11-1430) were alternately applied topically on forty patients with acne vulgaris. Therapeutic effects and side reactions of this regimen were compared with our previous studies of the treatment with retinoic acid alone and with retinoid alone. Compared with the treatment with retinoic acid alone, the therapsutic effect of the alternating treatment was relatively superior as indicated by the markedly reduced severity of local side reactions.

Monilethrix is a rare hereditary disorder of hair which was described by smith in 1879. The scalp hair is most frequently affected but the body or sexual hair are rarely affected. The affected hair shows periodic constrictions that break easily, so the hair could not grow more than a few millimetere long. It is thought that the node of the affected hair is normal and the thin internodal segment is deficient in hair matrix. Keratosis pilaris is generally an associated feature. We experienced a case of monilethrix with keratosis pilaris. The 4 years old male patient with monilethrix affected only scalp hair with keratosis. The family history was non-contributory.

BACKGROUND: Asthmatic patients frequently suffer cold-weather-associated respiratory symptoms. The sensitivity, specificity, accuracy and diagnostic value of isocapnic hyperventilation of cold air(IHCA) using a multistep method was investigated in patients suspected to have asthma. METHOD: One hundred and 29 adult patients who had an IHCA performed between july 1999 and December 2000, had an methacholine bronchoprovocation test because of a clinical suspicion of asthma. RESULTS: According to strict criteria, 50 were defined as asthmatics and 79 as symptomatic nonashmatics. There were no differences in age, sex and smoking state between the asthmatic and symptomatic nonasthmatic groups. There was a significant decrease in the percentage reduction in the forced expiratory volume in 1 second(FEV1) after the IHCA between the asthmatics(-10.0±6.8%) and the symptomatic nonasthmatics(-2.3±2.5%). The factors associated with a reactivity to IHCA were FEV1/FVC, FEF25-75/FVC and FEV1(% of predicted). The accuracy was highest using a 7% fall in FEV1; the sensitivity was 76% and the specificity 96%. CONCLUSION: IHCA is a specific, although not a sensitive, test for diagnosing asthma in adult patients. Furthermore, the diagnostic cut-off value of the different methods of IHCA need to be determined.

OBJECTIVES: This study was designed to assess the change of heart rate variability (HRV) at resting, upright, and psychological stress in anxiety disorder patients. METHODS: HRV was measured at resting, upright, and psychological stress states in 60 anxiety disorder patients. We used visual analogue scale (VAS) score to assess tension and stress severity. Beck depression inventory (BDI) and state trait anxiety inventories I and II (STAI-I and II) were used to assess depression and anxiety severity. Differences between HRV indices were evaluated using paired t-tests. Gender difference analysis was accomplished with ANCOVA. RESULTS: SDNN (Standard deviation of normal RR intervals) and low frequency/high frequency (LF/HF) were significantly increased, while NN50, pNN50, and normalized HF (nHF) were significantly decreased in the upright position compared to resting state (p < 0.01). SDNN, root mean square of the differences of successive normal to normal intervals, and LF/HF were significantly increased, while nHF was significantly decreased in the psychological stress state compared to resting state (p < 0.01). SDNN, NN50, pNN50 were significantly lower in upright position compared to psychological stress and nVLF, nLF, nHF, and LF/HF showed no significant differences between them. CONCLUSION: The LF/HF ratio was significantly increased after both physical and psychological stress in anxiety disorder, but did not show a significant difference between these two stresses. Significant differences of SDNN, NN50, and pNN50 without any differences of nVLF, nLF, nHF, and LF/HF between two stresses might suggest that frequency domain analysis is more specific than time domain analysis.

BACKGROUND AND OBJECTIVES: Thyroid disorders are common endocrine disease with various clinical symptoms. Biochemical function tests are important to detect thyroid function disorders, but guideline for screening of thyroid dysfunction is controversial. Therefore, in this study, we aimed to investigate the prevalence and clinical significance of thyroid dysfunctions with analyses of public screening and follow-up results on our hospital. MATERIALS AND METHODS: This study was performed on 3309 subjects (1753 men, 1556 women) that visited in our health promotion center for periodic health examination from January to June 2007, with review of medical records. Serum T3, Free T4, and thyroid-stimulating hormone concentrations were measured with radioimmunoassay using commercial kits, and ultrasonogram and scan of thyroid were conducted if needed. RESULTS: The study showed the prevalence of thyroid dysfunction was 11.8% (389 cases) and among the subjects, prevalence of undiagnosed hyperthyroidism and hypothyroidism were 1.8% (7 cases) and 3.1% (12 cases), subclinical hyperthyroidism and subclinical hypothyroidism was 0.5% (2 cases) and 4.9% (19 cases). However, prevalence of normal thyroid function with follow up clinically was 37.3% (145 cases). CONCLUSION: This study indicates significance of screening and confirmation through follow-up for thyroid disorders with high prevalence of thyroid dysfunctions with guidelines to minimize the false positive results.
