BACKGROUND: Langerhans cell histiocytosis (LCH) is a broad spectrum of clinical diseases having proliferation of Langerhans cells in common. LCH may be manifested in a variety of ways, ranging from a spontaneously regressing skin lesion to a multisystemic life-threatening disorder. Congenital self-healing reticulohistiocytosis is widely regarded as a limited form of LCH. It is present at birth or shortly thereafter and involute spontaneously. OBJECTIVE: Our purpose was to investigate the relationship between clinicopathologic characteristics and prognosis of LCH in children. METHODS: Six children with LCH were investigated clinically and histopathologically. Immunostains were performed with CD1a and S100 antibodies in 5 cases using paraffin-embedded sections and an electron microscopic examination was done in 1 case. RESULTS: Among the 6 cases of LCH, 4 cases were confined to the skin, and 2 cases showed internal organ involvement. All LCH confined to the skin showed resolution of the skin lesion in 1 year, and 2 cases involving internal organ showed bad prognosis. Histopathological findings showed large histiocytes with eosinophilic cytoplasm in common. Immunohistochemical stains (5 cases) showed positive reactions with CD1a and S-100, and electron- microscopical observation in one case demonstrated laminated dense bodies. There was no significant histopathological or immunohistochemical difference between LCH confined to the skin which showed resolution of lesions and LCH involving internal organs with grave prognosis. CONCLUSIONS: Clinical types of Langerhans cell histiocytosis could not be differentiated only from the histopathological findings of the skin. The distinction between Langerhans cell histiocytosis confined to the skin showing spontaneous resolution and congenital self-healing reticulohistiocytosis remains to be clarified.

PURPOSE: Recently, the growing interest in minimally invasive surgery and the development of instruments and accompanying techniques have allowed laparoscopic surgery to be performed in a wide range of urological fields. Herein, the procedures and results of 6 cases of hand assisted laparoscopic surgery (HALS) nephroureterectomy are reported. MATERIALS AND METHODS: The records of 6 and 5 patients, who had undergone either a laparoscopic HALS nephroureterectomy, with bladder cuff excision, or an open nephroureterectomy, with bladder cuff excision, were reviewed. RESULTS: The mean operation times were 194 (150-210) and 280 (250-310) minutes in HALS nephroureterectomy and open nephroureterectomy, respectively. The average pain scales recorded with HALS and classical open surgery were 1.5 (max. 2) and 7 (max. 8), respectively, on the second post operative day. CONCLUSIONS: HALS allows the operator to be notified with on-the-spot information and to have a feeling of complete control over the procedure, which helps to complete the operation in a shorter time, with the assistance of a tactile impression. Therefore, HALS can be concluded to be a better approach, which is a more acceptable procedure for the novice laparoscopic surgeon.

PURPOSE: The aim of this study was to analyze breast cancer screening behaviors in working women. METHOD: A total of 354 women over 20 years of age were recruited from three major occupational settings by convenience sampling. The Champion's Health Beliefs Model Scale-Korean version and a structured questionnaire for measuring regularity and accuracy of breast self-examination(BSE) were used. Data were analyzed using descriptive statistics, chi-square-test, ANOVA, and Duncan post hoc tests. RESULT: Women who have performed BSE and had both BSE and clinical tests were 49.2% and 32.8%, respectively, while 36.7% of the participants had none of the screening. The screening patterns were significantly different by individual characteristics of age, occupation, experiences of breast disease, education at workplace, and by the level of confidence in health beliefs (p<.01, p<.05). Only 4 % of women performed BSE regularly and the level of accuracy of the BSE was very low as well. CONCLUSION: Education at the workplace needs to emphasize the recommended guidelines and further increase the quality and results of the BSE for women's health.

Pulmonary embolism is a serious complication, which is well known in patients undergoing total hip or total knee arthroplasty or lower extremity fracture surgery. But, there are few literatures concerning pulmonary embolism after upper extremity surgery. Pulmonary embolism after minor upper extremity fracture surgery is extremely rare. We report a case of 66-year-old female patient that developed pulmonary embolism after percutaneous cannulated screw fixation for a greater tubercle fracture of the proximal humerus with literature review.

Nevus anemicus is a congenital anomaly characterized by pale macules of varying size and shape, and it is due to the increased sensitivity of blood vessels to catecholamines. However, the clinical features of nevus anemicus are not yet fully established. A clinical observation was made analyzing 26 cases of nevus anemicus over a 10-year period. Histopathological investigation in 6 cases, stain with Fontana-Masson in 4 cases, irradiation of ultraviolet B in 5 cases, digital infrared thermal imaging in 5 cases and color analysis using true-color imaging in 12 cases were also performed. The results were as follows: 1. The ratio of men to women was 1.2:1. The lesions were mostly(80%) present before the age of 18, but only 15% of the patients' lesions were present at birth. 2. The lesions were most frequently found on the face(33.3%) and neck(33.3%), followed by the chest(14.8%), lower extremities(7.4%) and back(7.4%). 3. Most patients(92.3%) had a single lesion. The extent of the lesions did not exceed 10% of the body surface area and the lesions did not show any progression or resolution. 4. The stainability of Fontana-Masson in nevus anemicus lesions showed no significant change compared with perilesional normal skin. 5. Irradiation of ultraviolet B ray(minimal erythemal dose to 80mJ/cm2) did not induce erythema on nevus anemicus lesions. 6. There was no significant temperature difference between nevus anemicus lesions and perilesional normal skin. 7. There was no significant correlation between chrominance and age. In conclusion, nevus anemicus in Korea shows the same incidence in both sexes, it usually arises at birth or childhood, but it may also develop later in life. Most patients show focal lesions that do not progress or resolve.
