Prurigo nodularis is a troublesome chronic dermatosis that showed unsatisfactory response to conventional therapies. Since thalidomide has been applied to the treatment of prurigo nodularis, although the action mechanism is still uncertain, many dermatologists have confirmed its effectiveness. We treated a 54-year-old male patient who had prurigo nodularis affecting the whole body for 10 years with 100 to 300mg of thalidomide daily as the sole therapy for 4 months. The skin lesions were flattened leaving postinflammatory hyperpigmentation and the pruritus also sub-sided. Two years after stopping thalidomide, no recurrence was observed.

The purpose of this study was to investigate effects of nutrition education program and pamphlet for the lower grades elementary students focused on individual daily needed food exchange units using Food Exchange System. Program consisted of four lessons (40 min/lesson), "5 major nutrients & function", "6 food group and sources", "daily needed food exchange units for normal body weight", and "smart snack choice and exercise". Pamphlet as activity book was developed for the program. The subjects were 3rd grade elementary students (educated group, 31 vs. non-educated group, 31). Educated group were lessoned as group and/or individual. We examined the differences in nutrition knowledge, dietary attitudes, dietary intakes and satisfaction of the program and pamphlet. In educated group, there were positive improvements on nutrition knowledge score "function and foods of 5 nutrients" and on dietary attitudes "type of breakfast and snacks". In the evaluation of dietary intakes according to KDRI, there were positive improvements on intakes level of riboflavin, vit. C, folate, Ca, P, Fe and Zn in educated group. In satisfaction with the program and pamphlet, contents, font size, visual, figure, difficulty and program curriculum were over 2.90/3.0. It showed that the developed nutrition education program and pamphlet focused on individual daily needed food exchange units using Food Exchange System improved nutrition knowledge, dietary attitudes and nutrients intake level in the lower grades elementary students.

Purpose: The purpose of this study is to use finite element analysis to predict the fatigue life of an implant system subjected to fatigue load by mastication (chewing force). The reliability and the stability of implant system can be defined in terms of the fatigue strength. Not only an implant is expensive but also it is almost impossible to correct after it is inserted. From a bio-engineering standpoint, the fatigue strength of the dental implant system must be evaluated by simulation (FEA). Material and Methods: Finite element analysis and fatigue test are performed to estimate the fatigue strength of the implant system. Mesh of implant is generated with the actual shape and size. In this paper, the fatigue strength of implant system is estimated: U-fit (T.Strong, Korea, internal type). The stress field in implant is calculated by elastic-plastic finite element analysis. The equivalent fatigue stress, considering the contact and preload stretching of a screw by torque for tightening an abutment, is obtained by means of Sine's method. To evaluate the reliability of the calculated fatigue strength, fatigue test is performed. Results: A comparison of the calculated fatigue strength with experimental data showed the validity and accuracy of the proposed method. The initiation points of the fatigue failure in the implant system exist in the region of high equivalent fatigue stress values. Conclusion: The above proposed method for fatigue life estimation can be applied to other configurations of the differently designed and improved implant. In order to prove reliability of prototype implant, fatigue test should be executed. The proposed method is economical for the prediction of fatigue life because fatigue testing, which is time consuming and precision-dependent, is not required.

BACKGROUND: It has been well known that patients with diabetes mellitus are prone to cutaneous infections, but whether superficial mycoses are truly more prevalent in diabetic patients is still controversial. OBJECTIVE: The purpose of this study was to determine the true prevalence of superficial mycoses in diabetic patients as comparing with non-diabetic, non-immunocompromised individuals. METHODS: We examined for evidence of superficial fungal disease in 137 diabetic patients and compared it with 146 non-diabetic non-immunocompromised ones. Potassium hydroxide preparations and fungus cultures were performed from all suspected lesions. RESULTS: Superficial mycoses were more common in diabetic patients(50%) than controls(31%) (p=0.0004), especially in the age group of 4th and 5th decades9p=0.011). The duration of diabetes mallitus or blood sugar levels were not significantly correlated with the prevalence of superficial mycoses.The organism most commonly isolated was Trichophyton rubrum in both groups(53% vs 79%) and Candida albicans was more prevalent in diabetic patients(34% vs 7%). More than 2 kinds of superficial mycoses were mose common in diabetic patients than controls(38% vs 16%). CONCLUSION: This study shows that the prevalence rate of superficial mycoses in diabetic patients is higher than that in controls and the in controls and the duration of diabetes mellitus or blood sugar levels were not significantly correlated with it.

BACKGROUND: Dermatophytoses show marked differences in their incidences, distributions, and causative organisms by age, sex, occupations, environmental conditions and geographic distributions. OBJECTIVE: We evaluated the recent distributions of dermatophytes and compared them with the previous reports in Seoul. METHODS: We evaluated the incidences of dermatophytes according to the patient's age and sex, isolated month, and the infection sites with 387 strains of dermatophytes isolated from the various forms of dermatophytoses during the period from August 1985 to July 1991 in Seoul. RESULTS: T. rubrum was the most prevalent dermatophyte in all age groups except the first decade. The incidence of M. canis was high in age groups below 20 years old relatively high incidences of T. mentagrophytes and T. interdigitale in age groups over 30 years old. Dermatophytes were frequently isolated in summer season, but the incidence of M. canis was relatively high in October and December. T. rubrum was the most prevalent dermatophyte from all forms of dermatophytoses except tinea capitis, but the incidence of T. rubrum was relatively low in tinea corporis. The incidence of T. mentagrophytes was relatively high in tinea unguium and tinea manus, and M. canis was isolated only in tinea corporis and tinea capitis. From the cases showing more than two forms of dermatophytoses. T. rubrum was isolated for the most part. CONCLUSION: This study suggested that there was a rise in the cases of t. rubrum infections in Seoul and in recent years the prevalence of M. canis infections has markedly increased but those of E. floccosum and t. mentagrophytes have decreased.
