We describe cytologic findings of two cases of pilomatrixoma which had been cytologically misdiagnosed as suspicious malignant and malignant lesions in 35 year-old and 22 year-old females who presented a palpable neck mass. The cytologic smears showed many basaloid cells with a high nuclear-cytoplasmic ratio, nuclear hyperchromatism and prominent nucleoli, keratinized squamous cells with pyknotic nuclei, foreign body giant cells, and chronic inflammatory cells in necrotic background. Retrospective view of this aspiration smear revealed that these findings were characteristic features of pilomatrixoma, and the evenly distributed chromatin pattern as well as the lack of nuclear pleomorphism were considered to be the differential points from malignant neoplasm. Pilomatrixoma is a benign neoplasm which should be included in differential diagnosis if the fine needle aspiration cytologic smear of a neck mass or subcutaneous mass of any site showed these features.

OBJECTIVE: To evaluate the viability and the characteristics of shed endometrial tissues obtained from menstrual fluid during in-vitro culture. METHODS: The menstrual fluids were collected using Wallace catheter from uterine cavity in 10 women with regular menstruation. The menstrual fluids were washed twice, and the pellets, containing blood cells and shed endometrium, were collected and diluted fivefold with Ham's F-10 medium containing 10% fetal bovine serum. The cell suspension was placed on culture dishes, and cultured for 7 days in an incubator. To evaluate the characteristics of the cultured endometrial cells, immunohistochemical (IHC) staining was performed using anti-cytokeratin and anti-vimentin antibody. RESULTS: The mean volume of menstrual fluids and pellets were 0.7ml and 0.3ml, respectively. Only 15% of the shed endometrial tissues were attached and proliferated in culture dishes, which was considered to have viability. Initially, endometrial epithelial cells and fibroblasts were attached and proliferated, and the area of these cells was increased according to prolong the culture time. Stromal cell colonys were located and proliferated on the epithelial cells. IHC staining showed strongly positive for cytokeratin in epithelial cells and for vimentin in stromal cells. In the confocal microscopic observation of 3-dimensional structure of cultured endometrium, cytokeratin-positive cells (epithelial cells) were located in the pheriphery and cytokeratin-negative cells (stromal cells) inside of the structure. CONCLUSION: From our study, shed endometrial tissues in menstrual fluid showed meaningful viability and closed relationship between epithelial cells and stromal cells during in-vitro culture. Thus, we suggest that the in-vitro culture system of shed endometrium is a suitable model for researches of endometriosis.

PURPOSE: The purpose of this study was to identified the male nurses' encounter in adapting themselves in the hospital settings dominated by the female nurses in number. METHOD: Data were collected through the in-depth interview of 16 male nurses and analysed through the grounded theory methodology. RESULT: The behaviors of male nurses for job-adaptation can be summarized as a series of struggles to consolidate their own ground. They have made tremendous efforts to hold their own ground in the nursing profession composed of a large numbers of female nurses, while they have experienced many difficulties and problems as minorities. They have struggled to adapt themselves professionally through efforts such as; challenging the social and professional barriers, identifying the job identity, empowering themselves through self-development and dedication, expanding their influence among colleagues. In spite of these efforts, they had the perception that nursing is not a lifelong occupation for them. Thus, they had tendency to find outlets of change to occupations. CONCLUSION: A specific strategy is needed to provide an environment that is helpful for males in integrating into and adapting to the nursing profession.

PURPOSE: This study aimed at uncovering the experience of adaptation of the new nursing staff in hospital setting. METHODS: For this study, 15 new graduate nurses participated. The data was collected through the in-dept interviews and analysed in terms of Strauss and Corbin's grounded theory methodology. RESULTS: The core category was identified with "entering orbit". The new graduate nurses, who experienced the taeoom because of their unskilled professions, tried to enter orbit by overcoming difficult situations through reducing stress, maintaining good interpersonal relationship, grasping, compensating, persisting, and introspecting. Noticeably, in the process of adaptation, negative image of nursing, conflict of interpersonal relationship and the educational program for the new nursing staff had effect on the intervening factors. Finally, this study confirmed that the processes of new nurses' adaptation are confusing, confrontating, becoming a member and settling in hospital setting. CONCLUSION: Therefore, the educational programs reflecting new nursing staffs' experiences should be developed.

PURPOSE: This study was conducted to investigate the actual condition of an analgesic intake of workers exposed to organic solvents. METHODS: The questionnaire and/or interview survey was conducted on workers who worked for small-scale factories of less than 50 employees when they visited an university hospital for a regular physical check-up required by the company. RESULTS: Among workers exposed to organic solvents, the proportion of those who took more than four tablets of analgesics a day or over 10 tablets of analgesics a month were 1.7 times and 1.5 times higher respectively than other workers not exposed to solvents. This indicates that the analgesic intake of workers exposed to organic solvents may be a threat to their health. As for the source of analgesics, individual purchases at drug store were about 12 times more common than doctors' prescriptions in both groups. This imbalance warns us of the possibility of analgesic abuse. The most common reason for analgesic intake was due to a headache in both groups. CONCLUSION: These results show that workers exposed to organic solvents take many more analgesics than non-exposed workers, so they have a greater chance of drug abuse.

The radiologic and clinical findings of foreign bodies in the chest of children are well recognized. Foreign bodies in adults are infrequent, however, and the radiologic findings of these unusual circumstances have rarely been described. We classified various thoracic foreign bodies into three types according to their cause: Type I, Aspiration, Type II, Trauma or Accident; Type III, Iatrogenic. This pictorial essay will illustrate the radiologic findings and consequences of thoracic foreign bodies in adults, which have rarely been described in the radiologic literature. The clinical significance of thoracic foreign bodies will be also be discussed.

The purpose of this research was to find out the effect of chest physiotherapy on the amount of tracheal secretion and PaO2. After changing position of the neurosurgical patients who had tracheostomy cannula, experimental treatments were applied as bellows, manual chest percussion on group I, chest percussion and manual chest vibration on group II, chest percussion and mechanical chest vibration on group III were done. After these trials, we have analyzed the efficacy of each procedures comparing the group differences in the quantity of tracheal secretion and PaO2. Target samples were sixty patients aged between 20 to 60 who have tracheostomy state and decreased consciousness status that were admitted in NICU of a university hospital from June 1 to August 31, 1999. They assigned randomly into three experimental groups. To compare the effect of each interventions, tracheal secretion quantity was measured and PaO2 was analyzed via arterial blood gas analyzer. The data were analyzed by ANCOVA of 5% significance level using SPSS P/C program. The results were as bellows. 1) The first hypothesis " There is a difference in the quantity of the secretion among Group I, Group II and Group III" was accepted.(F=29.27, p=0.00) 2) The second hypothesis "There is a difference in PaO2 among Group I, Group II and Group III" was rejected.(F=1.71,p=0.19) From this study results, positional change and manual chest vibration including chest percussion were the most effective treatment to get maximum amount of tracheal secretion and it was confirmed that mechanical chest vibration also made much better effect than sole chest percussion method. Therefore, we concluded that the mechanical or manual chest vibration with chest percussion is more effective respiratory care method than the sole chest percussion.

OBJECTIVES: The aim of this study was to compare root canal volume change and canal transportation by Vortex Blue (VB; Dentsply Tulsa Dental Specialties), ProTaper Next (PTN; Dentsply Maillefer), and ProTaper Universal (PTU; Dentsply Maillefer) nickel-titanium rotary files in curved root canals. MATERIALS AND METHODS: Thirty canals with 20°–45° of curvature from extracted human molars were used. Root canal instrumentation was performed with VB, PTN, and PTU files up to #30.06, X3, and F3, respectively. Changes in root canal volume before and after the instrumentation, and the amount and direction of canal transportation at 1, 3, and 5 mm from the root apex were measured by using micro-computed tomography. Data of canal volume change were statistically analyzed using one-way analysis of variance and Tukey test, while data of amount and direction of transportation were analyzed using Kruskal-Wallis and Mann-Whitney U test. RESULTS: There were no significant differences among 3 groups in terms of canal volume change (p > 0.05). For the amount of transportation, PTN showed significantly less transportation than PTU at 3 mm level (p = 0.005). VB files showed no significant difference in canal transportation at all 3 levels with either PTN or PTU files. Also, VB files showed unique inward transportation tendency in the apical area. CONCLUSIONS: Other than PTN produced less amount of transportation than PTU at 3 mm level, all 3 file systems showed similar level of canal volume change and transportation, and VB file system could prepare the curved canals without significant shaping errors.
