The origin of osteoclast-like giant cell tumor (OGCT) of the salivary gland has been debated because the prototypic cells of osteoclast-like cells and mononuclear stromal cells are largely unexplained in this gland. Bone marrow-derived CD14+ and CD45+ monocyte-derived multipotential cells (CD14+/CD45+ MOMC) may be one of the possible origins of OGCTs of salivary glands, which have never been explored in salivary OGCTs. We present a case of OGCT accompanied with carcinoma ex pleomorphic adenoma in the parotid gland of a 67-year-old Korean female. The tumor presented as a rapidly growing cervical mass comprising a central area of carcinoma ex pleomorphic adenoma and a peripheral circumferential area of OGCT. The immunohistochemical staining pattern was phenotypically consistent with bone marrow-derived CD14+/CD45+ MOMC. This case is the first report of a salivary OGCT in Korea.

Gestational trophoblastic tumors including choriocarcinoma bave become one of the most curable human malignancies with an overall cure rate exceeding 90%. Although systemic chemotherapy is the initial treatment for chorio- carcinoma, some patients with chemotherapy-resistant choriocarcinorna can be treated by integration of cbemotherapy, surgery and radio- therapy. We report two cases of persistent localized choriocarcinoma which was treated by surgical intervention.

Open discectomy is one of usual treatment for herniated intervertebral disc. We may expect the reduction of height of intervertebral disc due to decreased volume by partial resection of herniated disc. But the effect of decreased height of intervertebral disc space to posterior joint and spinal canal has not been identified, and the correlation between the amount of reduced height and the changes of range of motion has been undetermined. Thus, we analyzed radiologic changes of disc height and segmental motion by the flexion-extension view in 20 patients who had undergone discetomy for prolapsed intervertebral disc from June 1989 to January 1991 who could be followed up for 3 years or more. As a result, lumbar discetomy associates with 1) significant decrement of disc height (average 14%), 2) decreased disc motion of involved segment without hypermobility (average 34%), 3) hypermobility of adjacent segment, 4) and posterior facet overriding consistent with recurred low back pain.

PURPOSE: This study was designed to compare conventional renal and contrast enhanced magnetic resonance angiography (CRA & CE-MRA, respectively) for the preoperative evaluation of living renal transplant donors. MATERIALS AND METHODS: Between September 2002 and November 2004, forty-five consecutive live renal transplant donors underwent preoperative evaluations of the renal vessels, using both CRA and CE-MRA before the donor nephrectomy. The intraoperative findings of the number of renal vessels were compared with those of CRA and CE-MRA, respectively. RESULTS: Both angiographic modalities were able to detect multiple renal arteries and veins, with overall agreement between CRA and CE-MRA of 97.8 and 97.8%, respectively. The overall accuracies for predicting the number of renal arteries and veins, relative to the intraoperative findings, were 91.1 and 91.1% for CRA and 88.9 and 95.6% for CE-MRA, respectively. The CE-MRA missed 5 accessory renal arteries, whereas CRA missed 4 cases. Despite the undetected cases, there was no significant intraoperative morbidity. Additionally, renal cysts seen on CE-MRA were not detected by CRA. CONCLUSIONS: Our findings suggest that noninvasive CE-MRA is a promising substitute for CRA to evaluate the renal vessels of live renal transplant donors.

BACKGROUND: Atopic dermatitis, characterized by dry, flasky, easily irritated skin, is the most common form of dermatitis seen during childhood. Infants with atopic dermatitis and other eczematous conditions need special dermatologic care to hydrate their skin and to minimize contact with irritants or allergens. OBJECTIVE: The purpose of our study is to evaluate the safety and efficacy of the skin products developed for children. METHODS: Twenty-eight normal children and 26 children with atopic dermatitis were evaluated clinically after using following commercal skin products : (lotion, cream, shampoo, soap, face wash wash) for 2 weeks. Water content of the skin of 14 volunteers was measured serialy over 8 haurs at 2 hour intervals after the application of each skin product. The skin pH of 16 volunteers was also measured serialy over 60 minutes at 30 minute intervals after application. We performed visual skin erythema grading, skin erythema grading by dermaspectrometer, transepidermal water loss measurement, skin water content measurement, and keratinocyte morphology observation by D-squame after the application of the skin products to 13 volunteers for 4 days.

BACKGROUND: Echocardiographically detected left ventricular(LV) hypertrophy is a risk factor for cardiovascular morbidity and mortality. A better understanding of the determinants of LV mass may aid in strategies directed toward the promary and secondary prevention of LV hypertrophy and its consequences. Previous studies have reported that male gender, arterial blood pressure(BP), obesity, age, aortic valvular stenosis, dietary sodium, endocrine factors, and physical activity are positively correlated with LV mass. Of these determinants male gender, hypertension, and obesity are well known but age and blood pressure in healthy adults are controversial. To assess the determinants of LV mass, the relation of 2-dimensional(2D) echocardiographically determined LV mass to body mass inedx(BMI), age, sex, casual BP, and 24 hour ambulatory blood pressure(ABP : systolic, diastolic, and mean BP of 24 hour, day-time, and night-time) was examined in healthy adults. METHODS: The study population consisted of 200 healthy adults who were normotensive, nonobese, and had no evidence of cardiovascular disease(range in age from 20 to 69 years, five decades, 20 men and 20 women per each decade). LV mass was derived from area length method measurements obtained by 2D echocardiography and corrected for height. ABP monitoring was performend over 24 hour(divided into day-time(6am-10pm) and night-time(10pm-6am)periods) with 30 minute inervals. RESULTS: 1) BMI was significantly and independently related to LV mass corrected for height (p<0.001, partial R2=0.31 in men and 0.43 in women). An increase of BMI by 1 kg/m2increased LV mass corrected for height by 1.9g/m in men and 2.0g/m in women. 2) Age was significantly and independently related to LV mass corrected for height(p<0.001, partial R2=0.15 in men and 0.17 in women). The increments of Lv mass corrected for height per decade were 2.1 g/m in men and 3.4 g/m in women. 3) Gender was significantly and independently related to LV mass corrected for height(p<0.001, partial R2=0.12), which was greater in men than in women by 6.34g/m. 4) Casual Bp and 24 hour ABP were not significantly associated with LV mass corrected for height in total population and women, and 24 hour systolic BP was significantly related to LV mass corrected for height only in men(p<0.001) with weak partial R2(0.05). CONCLUSION: BMI, age, and male gender were statistically significant and independent correlates of LV mass corrected for height(p<0.001). Maintenance of ideal body weight and normal BP, weight reduction in obese persons and BP control inhypertensive patients may contribute to the primary and secondary prevention of LV hypertrophy and its sequalae.

Fungal infections are associated with the lowest incidence of post-operative infection following renal transplantation. These infections, however, are associated with a high mortality rate. A 58-year-old man who had received a kidney transplant presented with confused mental status. A brain computed tomography (CT) scan showed a 5.4 cm-sized, septate and thin-walled ring-enhancing lesion. The patient underwent aspiration and drainage of the brain lesion. Aspergillus fumigatus was stained in cultures of the aspirated material. Following surgery, the patient was treated with voriconazole for four months. After four months of anti-fungal treatment, the size of the brain abscess was decreased and serum creatinine was 1.5 mg/dL. Here, we present details of the case, which showed a favorable outcome with the combination of early surgery and voriconazol administration.

Heart failure is the pathophysiological state characterized by ventricular dysfunction and associated clinical symptoms. Decreased cardiac output or peripheral vascular resistance lead to arterial underfilling. That is an important signal which triggers multiple neurohormonal systems to maintain adequate arterial pressure and peripheral perfusion of the vital organs. The kidney is the principal organ affected when cardiac output declines. Alterations of hemodynamics and neurohormonal systems in heart failure result in renal sodium and water retention. Activation of sympathetic nervous system, renin-angiotensin-aldosterone system and non-osmotic vasopressin release stimulate the renal tubular reabsorption of sodium and water. Dysregulation of aquaporin-2 and sodium transporters also play an important role in the pathogenesis of renal sodium and water retention.
