BACKGROUND: Reconstitution of hematopoiesis by means of peripheral blood stem cells(PBSC) has been widely used in patients with hematologic malignancies or solid tumors. We analyzed our experiences of PBSC collections with a MCS3p(Haemonetics Corp. Braintree, MA,USA) and investigated factors that may affect the collection of PBSC. METHOD: The forty-seven harvests in 11 cancer patients(median age 48, 4 males: 7 females) were performed during marrow recovery after administration of anticancerous regimens and and hematopoietic growth factors. RESULTS: Median number of WBC & mononuclear cells(MNCs) in preapheresis was 4,700/pl and 1,472/pl, retrospectively. A total of 11.2 x 10'(range 5.4-17.0) MNCs were collected from 7.2 l (5.5-8.9) blood processed per procedure. The mean percentage of CD34 positive cells in the product was 1.9%(0.9-2.9). Collection efficiency was 58.1%. While age of patients or total processed blood volume did not affect for total number of MNC collected, the number of WBCs including MNCs on the day of harvest was an importanr factor for higher yield of MNCs(P<0.05). CONCLUSION: We concluded that Haemonetics MCS3P. Is a fully automated blood cell separator with good collection efficiency for hematopoietic progenitor cells.(Korean J Blood Transfusion 10(1): 35-41,1999)

Pyelocaliceal diverticulum is a well recognized uncommon entity, usually noted incidentally on excretory urography by lack of clinical symptoms, About 500 cases had been reported with similar entity till 1975. We report 6 cases of stone-containing pyelocaliceal diverticula and additional one case and the literature has been reviewed briefly.

Partial Unilateral Lentiginosis (PUL) is a rare pigmentary disorder characterized by the numerous lentigines confined to a body segment, with a sharp demarcation at the midline. We report two cases of PUL. A 38-year-old woman had asymptomatic discrete small hyperpigmented macules that were scattered on the T7~L1 dermatomes on the left side of her trunk and were clearly demarcated in the midline on both anterior and posterior sides. In the other case, an 18- year-old woman had hyperpigmented macules that were scattered on the left neck, shoulder, and anterior chest. Other anomalies including neurofibromatosis, neurologic anomalies, and multiple lentiginous syndrome were not related in both cases. We report two cases of PUL having no other anomalies.

45 cases of proved renal cell carcinoma which were operated on during last 10 years between March 1972 and February 1982 in the department of Urology of Yonsei University College of Medicine were clinically observed with the reference to the operative morbidity due to the surgical incisions of both anterior transperitoneal approach (25 cases or 55%) and modified thoracoabdominal approach which is 11th-rib resection with extrapleural and transperitoneal exposure (20 cases of 45%). According to the experience with modified thoracoabdominal incision for the 17 radical nephrectomies and 3 open biopsies and through the review of the literatures, some results were obtained and summarized as follows. 1. Modified Thoracoabdominal approach is superior to the anterior transperitoneal approach for the operation of renal malignancy because of better exposure for the renal pedicle and upper pole as well as low morbidity rate (1:1.6). 2.We could also be sure by our self experiences of a few advantages of Modified Thoracoabdominal approaches as others reported previously. (1) An undisturbed intrathoracic space avoids a source of complications. (2) Because of adequate exposure of renal pedicle and upper pole even in the large renal tumor, operativemanipulation is easier and safer. (3) As muscle layers to be cut are not heavy, postoperative pain is less complained. The incision is also relatively simple to make and close. (4) Modified Thoracoabdominal approach is worth to apply to any urologic operations for the kidney and upper ureter. 3. In case tumor thrombi were involved in the supradiaphragmatic vena cava and vena caval resection is inevitable, either midline abdominal incision with sternotomy or conventional thoracoabdominal incision should be chosen rather than Modified thoracoabdominal approach.

Epidermoid Cyst is a very rare benign neoplasm of the testis which represents about 1% of all testicular tumors. Ultrasonography findings of epidermoid cyst are so variable in reported cases that it is not eas y to diagnose preoperatively. The echogenecity of mixed echoic. it may show hyperechoic rim, and rarely shows target apperance. Target appearance may be a specific finding of epidermoid cyst, and it may be helpful to diagnose preoperatively. we describe a case of epidermoid cyst of the testis demonstrating double target sign on ultrasonography.

OBJECTIVE: The aim of the present study is to assess the prevalence and related risk factors of suicide ideation among middle and high school students in an urban area. METHODS: We surveyed 3,691 middle and high school students (2,159 male, 1,532 female, 11-19 years of age) using a self-report questionnaire that covered basic socio-demographic data, academic achievements, presence of physical or psychiatric illness, sleep duration on weekdays, time spent at private academies on weekdays and weekends, and subjective needs for counseling. The Beck Depression Inventory (BDI) and Reynolds' Suicidal Ideation Questionnaire (SIQ) were included in the survey. RESULTS: The prevalence of students with high suicide ideation (SIQ > or = 62) was 4.6%. In a logistic regression model, female sex (p = 0.002), younger age (p < 0.001), poor academic achievement (p = 0.043) and higher score of BDI (p < 0.001) were associated with a higher SIQ score. In addition, younger age (p = 0.045) and a higher BDI score (p < 0.001) were associated with a higher SIQ score adolescents having high suicide ideation (SIQ > or = 62). CONCLUSION: Related risk factors of suicide ideation in adolescents were female sex, younger age, poor academic achievement, and a depressive mood. It would be especially helpful to pay more attention to younger adolescents and a depressive mood as a high-risk group. The understanding of these factors will be helpful for providing an effective suicide screening and prevention program for adolescents.
