Acinic cell tumor, a rare tumor of the salivary gland origin, consists of cells similar to the serous cells of the salivary gland. The tumor is almost exclusively paroti4 gland origin, accounting for 2. 7 to 4. 0% of all parotid tumors. The tumor is not,benign but has at least a low-grade malignant potential. We described herein a case of acinic cell tumor which had occurred on an unusual site, right inner epicanthal area of a 9-year-old girl Microscopically, a hematoxylin-eosin stained biopsy specimen showed rnany lobules com of round or polyhedral tumor cells. Each tumor cell had distinct cell membrane, clear cytoplasm, and relative1y eccentric nucleus. The cytoplasm of tumor cell cantaine4 diastase resistant PAS-positive material.

Multicystic ovary was first described by Silver in 1958 as a rare case feature of acquired primary hypothyroidism. In 1980, Lindsay reported four girls with hypothyroidism associated with multicystic ovary diagnosed by pelvic ultrasonography. The mechanism of ovarian cyst formation and pseudoprecocious puberty in severe hypothyroidism in childhood are unknown. Increased ovarian sensitivity to GnRH and increased TSH level which acts on FSH receptor is one of the mechanism explained. We report a case of a girl with primary hypothyroidism presented with pseudoprecocious puberty and giant follicular ovarian cyst with torsion.

Control of tuberculosis is threatened by widesread emergence of drug resistant Mycobacterium tuberculosis. Rifampin is a key component among therapeutic regimens for the tuberculosis; therefore patients in whom resistance to this drug develop have a poor outlook, particularly if rifampin resistance is associated with resistance to other tuberculosis drugs. The purpose of this study was to detect the mutation in rpoB gene of rifampin resistant M. tuberculosis in Korea and to evaluate the usefulness of the method in clinical aspects. A sample of 80 M. tuberculosis was studied, and it included 40 rifampin resistance isolates and 40 rifampin sensitive isolates by conventional methods. The detection method involved the amplification by polymerase chain reaction (PCR) of the Rif' region and the identification of mutations by single-strand DNA conformation polymorphism analysis (SSCP) of the amplification products (157 bp). Mutation were identified in 39 of 40 rifampin resistant isolates, and in 1 of 40 rifampin sensitive isolates.

PURPOSE: The purpose of this study was to examine the levels of burnout experienced by Korean hospital nurses (N=198), and to identify predictors of their nursing outcomes such as job performance, work satisfaction, and productivity. METHOD: Hierarchical multiple regression was used to identify predictors of each nursing outcomes. Included predictors were nurses' general characteristics, work- related characteristics (role stress and perceived control), and burnout. Results: Korean nurses experienced higher levels of burnout compared to the cutoffs suggested by Maslach and Jackson (1986) and to those in the USA. For each nursing outcome, predictor variables explained 39% of the variance in role performance, 30% of the variance in work satisfaction, and 38% of variance in productivity. Higher personal accomplishment, lower role ambiguity, being staff nurses, and lower emotional exhaustion were related to higher job performance, and higher productivity. Lower role conflict and role ambiguity were also related to higher work satisfaction. CONCLUSION: Based on the findings of this study, managemental interventions for nurses to reduce their burnout experience are needed. Further study in this area is warranted.

Control of tuberculosis is threatened by widespread emergence of drug resistance in Mycobacterium tuberculosis. Understanding the molecular basis of resistance might lead to development of novel rapid methods for diagnosing drug resistance. Rifampin is a key component among therapeutic regimens for the tuberculosis; therefore, patients who have drug resistance do not convalesce satisfactorily. The molecular mechanism of resistance to rifampin in M. tuberulosis has been elucidated. Substitutions of a limited number of highly conserved amino acids encoded by the rpoB gene are responsible for the ""single-step"" high-level resistance of M. tuberculosis to rifampin. Currently, two genotype-based protocols allow drug test from minimally grown cultured materials: (i)mutation identification by direct sequencing of PCR-amplified material. and (ii)mutation screening by PCR-SSCP. The purpose of this study is to evaluate the usefulness of the both methods. A sample of 75 isolates of M. tuberculosis was studied, and it inculded 36 rifampin-resistant strains and 39 rifampin-sensitive strains by conventional methods. Mutaions were identified in 36 rifampin-resistant isolates but in none of 39 sensitive isolates. All mutations were clustered within a region of 23 amino acids. Both methods allow detection of rifampin resistance in 2 to 3 days and will thus help in the early management of infection by M. tuberculosis.

The purposes of this study were to investigate importance level and performance frequency of the dietitians' duties and task elements, to examine the actual condition of education and need for education, to analyze the interrelation between their tasks and education, and to provide the direction of education for the contracted Business & Industry (B & I) foodservice dietitians. The task elements of receiving, ordering, HACCP management and directing serving process were done almost every day. In terms of the importance of tasks, food sanitation management, personnel sanitation management, receiving and ordering were high. Meanwhile, the computerization of their works was being carried out on the whole, showing a higher frequency in all the details of procurement management and accounting management, as well as task elements such as menu planning, leftover and food waste management, HACCP management and human resource management. In the past three years, HACCP management, cost management, planning work schedule and allotting a task, general business and sale bond management were increased most and rapidly. For the actual condition of education, dietitians got more education for the duty of sanitation, safe and facility/utility management than any other duty, while they did less education of procurement management and office management than others. Meanwhile, the education for sanitation, safe and facility/utility management and accounting management were very much required. For the relationships of frequency of duty and the necessity of education, seven task elements including food sanitation management were correlated positively. Eighteen tasks besides menu planning had a significant positive correlation between the importance of duties and the necessity of education.

Talus is an important structure of the ankle joint and its function is critical for ambulation and weight bearing. The talus fracture is rare, but the complications of fracture and dislocation are serious and resulting in avascular necrosis, osteoarthritis. So its treatment is carefully considered at initial status. Authors reviewed 11 cases of fracture and dislocation of the talus treated at Yeungnam university hospital from 1984 to 1991. The longest follow up was 8 years and shortest, 1 years. The results were as follows. 1. There were all males, the average age was 30 years old. 2. The most common cause was fall down (8 cases), and next traffic accident (2 cases), sports injury (1 case). 3. According to Marti-Weber classification, 1 case was type I, 1 in type II, 4 in type III and 5 in type IV. 4. The method of treatment were open reduction and internal fixation in 6 cases, the others were closed reduction in 5 cases. 5. Final results (by Hawkins grading system) were as follows, 3 cases were excellent, 4 cases were good, 1 case was fair and 3 cases were poor. 6. Complications were AVN in 2 cases, degenerative arthritis in 8 cases, malunion in 1 case. 7. The range of motion of the ankle joint was relatively preserved (74%), but in the subtalar joint it was decreased (43%)
