We report two cases of linear focal elastosis. They are a 16-year-old girl and a 14-year-old boy who had had asymptomatic, several, yellow-red, slightly elevated, palpable, striae-like lesions on their middle and lower back since their early childhood. Light microscopic examinations of skin biopsy specimens demonstrated dermal thickening and focal increases of thin wavy fibers in the upper and mid-dermis but no changes in the epidermis. Verhoeff-van Gieson stains for elastic fiber revealed aggregated, clumped, curled, or fragmented elastic fibers.

This study was performed to compare the amount of blood flow from left and right side heart using Doppler echocardiography and Fick method. The pulmonary blood flow (Qp), aortic blood flow (Qs) and Qp/Qs ratio were noninvasively evaluated by two dimensional Doppler echocardiography in 10 patients with ventricular septal defect in children, aged 2 years to 15 years (mean+/-SD=7.1+/-4.9 years). Cardiac catheterization was performed within 2 days after examination of Doppler echocardiography in all patients. Systemic and pulmonary blood flow was calculated by using Fick principle, based on measured oxygen consumption and measured blood oxygen saturation. The Doppler frequency shift was analyzed by computer system combined with Meridian Echocardiography System. Comparison of Qp, Qs and Qp/Qs ratio obtained by invasive methods and by two-dimensional pulsed wave Doppler echocardiography showed a correlation of 0.679 in Qp, 0.710 in Qs and 0.639 in Qp/Qs ratio (p<0.05).

Trichilemmal carcinoma is a rare tumor that is located predominantly on sun-exposed skin of the elderly. It is thought to be related to the external root sheath of the hair follicle and the malignant counterpart of a trichilemmoma. We report a case of trichilemmal carcinoma in a 88-year-old woman who had a 10 year history of a single, dark brown tumor on the right preauricular region. In her past medical history, it had been excised twice at a private clinic without a histopathological evaluation and recurred 2 years later. Histopathological findings showed atypical clear cells resembling those of the outer root sheath. Tumor cells showed PAS-positive cytoplasm. Immunohistochemistry revealed positive high molecular weight cytokeratin expression. To our knowledge, this is the second case of trichilemmal carcinoma in the Korean literature. (Ann Dermatol 100) 175178, 1998).

The authors did clinical analysis for 37 cases, ranging from 5 to 13 year old of age and following result obtained. 1. In group I partial involved type had brightful prognosis even in the neglected the cases. 2. Ischeal brace did not give any help to group II & III but in group I, it gave some help to the prognosis. 3. In untreated cases of old age group developed early arthritic changes. 4. The inital radiological bony changes in early L-C-P. cases was the demineralization of the subchondral area and subsequently subohondral vaccum phenomena followed.

The knee is a weight-bearing joint which is subjected to a great variety of static and dynamic loads. The comminuted fracture of the knee is caused by severe violent trauma, which requires well planned therapeutic procedures because of restoration of joint surface and avoidence of subsequent joint stiffness. authores have experienced 8 cases of various types of comminuted fractures of the knees at the department of orthopedic surgery, The National Medical Center, during the years from 1967 to 1972 They were analized and concluded as following. 1. The mode of the injury was considerably higher in falling type of trauma as 4 out of 8 cases Type III of comminuted fracture of the tibial plateau had higher incidence, 4 out of 5 cases and Grade III type of comminuted fracture of the femoral condyle was 2 out of 3 cases 2. 2 cases out of 8 had complicated injuries, such as peroneal nerve injuries in the Type III of comminuted fracture of the tibial condyle and meniscus injury in 1 case. 3. Conservative treatment was given to 2 cases in 1 of Group 1 and 1 of Group III type of comminuted fracture of femoral condyle, and open reduction & internal fixation was given to 6 cases with satisfactory result in all cases Average healing time was 73.5 days. 4. 1 case was complicated after operation by superficial wound infection but healed up without difficulty.
