Scanning electron microscopic(SEM) examination of hair is an efficient and definite method for the diagnosis of hair anomaly. The Hair specimen is placed on a stub, gold coated, and directly viewed without prior fixation or treatment for identification. We have analyzed 25 cases of scalp hair and 2 cases of eyebrow that were sampled with the suspicion of hair anomalies at Seoul National University Hospital during the last 7 year period from January 1988 to June 1992. All 27 cases had certain abnormalities of the hair. They consisted of monilethrix(1 case), hair casts(4 cases), pili torti(1 case), uncombable hair syndrome(1 case), trichorrhexis nodosa(5 cases), woolly hair(5 cases) and other anomaly(1 case). Some cases of them were mixed with two or three anomalies in hairs. Their combinations were; hair casts and woolly hair(1 case), hair casts and pili torti and uncombabla hair syndrome(1 case), hair casts and uncombable hair syndrome and trichorrhexis nodosa(1 case), trichorrhexis nodosa and uncombable hair syndrome(3 cases). Most of these defects included brittleness of scales and distortion of the hair shaft.

In children, snapping knee syndrome and joint pain with the loss of physiological hyperextension strongly suggests a diagnosis of a torn discoid meniscus. We performed arthroscopic meniscectomy to treat torn discoid lateral meniscus on 19 knees and open meniscectomy on 9 knees of 26 children(average age: 10.9 yrs) from September, 1983 to October, 1993 at Guro hospital. According to Ikeuchi's grading system', excellent results were obtained in 14, good in 11, fair in 2 knees and poor in 1 knee which was associated with osteochondritis dissecans. The knees treated by partial meniscectomy showed less Fairbank's radiologic changes than those by total meniscectomy during the average follow-up 4.2 years(minimum 1 year, maximum 7 year 11 months).

PURPOSE: A common finding of carotid artery on magnetic resonance angiograms(MRAs) is a signal dropout along the posterior wall of carotid bulb due to reverse flow. The purpose of this study is to evaluate variable flow patterns on bifurcated carotid arterial phantoms using steady-state flow. MATERIALS AND METHODS: We designed phantoms of a bifurcated carotid artery with acrylic materials. Flow patterns were evaluated with axial and coronal imaging of MRA(2D-TOF, 3D-TOF), color Doppler imaging, and computational fluid dynamics (CFD) within the phantoms constructed of an automated closed-type circulatory system filled with 4% sugar solution. These findings were compared with findings obtained from normal volunteers. RESULTS: Axial 3D-TOF MRA images exhibited closer resemblance to the contour of the inner wall of phantoms when compared to coronal 2D-TOF MRA imaging. However, 2D-TOF MRA showed good contrast difference of signal intensities between forward flow area and reverse flow area. Dark zones with reduced signal intensities due to reversed flow were separated from the outer wall of the internal and external carotid arteries by a thin layer of forward flow along the wall on the source slice image of MRA. The general hemodynamics of the phantoms on MRA were identical to hemodynamics on color Doppler imaging and CFD. The results obtained with the phantoms matched the findings on normal volunteers. CONCLUSION: Although representations of bifurcated carotid arterial phantoms on axial 3D-TOF MRA were excellent if ideally desinged, the zone of reversed flow could be a significant factor in creating distorted image when the zone of reversed flow contacted directly with curved or deformed arterial wall.

We report an extremely rare case in which two tuberculids, papulonecrotic tuberculid and erythema nodosum, occurred together. A 16-year-old girl had two types of clinically distinct lesions; asymptomatic necrotic papules on the upper and lower extremities and painful subcutaneous nodules on the legs. A Mantoux test showed a strong positive reaction. Histopathologic findings of the necrotic papule and subcutaneous nodule were consistent with papulonecrotic tuberculid and erythema nodosum, respectively. There was no extracutaneous focus of tuberculosis. Polymerase chain reaction for tuberculous bacilli in the papulonecrotic tuberculid lesion revealed a negative result. Antituberculous therapy brought a rapid clinical improvement of both lesions.

BACKGROUND: Neopterin is released from monocytes/macrophages specifically by stimulation with interferon-γ. Therefore the increase refers to the activation of T lymphocytes. OBJECTIVE: Our objective was to examine the potential role of neopterin in the cell mediated immune response to Behçet's disease. METHODS: We studied 67 patients of Behçet's disease classified by Shimizu and a control group of 30 normal healthy people. Serum neopterin was detected by radioimmunoassay technique. RESULTS: The serum neopterin concentration of the group with Behçet's disease was significantly elevated, compared with the control group (6.36 nmol/ml vs 3.63 nmol/ml). The increase of neopterin concentration was well correlated to the clinical severity of the diseases in increasing order. CONCLUSION: Our data suggest that the T lymphocyte derived IFN-γ which stimulates the production of neopterin has some role in the pathogenesis and clinical severity of Behçet's disease.
