A 52-year-old man with multiple myeloma developed cutaneous nodules while being treated with melphalan and prednisolone. A biopsy specimen showed dermal infiltration by well differentiated plasma cells similar to those found on bone marrow biopsy. The use of peroxidase anti-peroxidase to demonstrate the monoclonality or polyclonality of the cytomplasmic immunoglohulins in the tumor cells revealed a positivity for IgG and 1 chain (ie, monotypic staining). Ultrastructurally, each plasmacytoma cell contained varyting amounts of rough endoplasmic reticulum and Golgi-apparatus. The cutnneous nodules completely disappeared after radiotherapy

The study was undertaken to clarify any quantitative abnormalities in peripheral blood T lymphocytes and T subsets, mediating cell meliated immunity, and the presence of any relation between the degree of quantitative abnormalities and extent of skin lesions and activity of disease in patients with psoriasis by monoclonal antibodies. The results were as follows. 1. Mean percentages of total and suppressor T lymphocytes in 39 patients with psoriasis are significantly decreased as compared with those in 32 controls. Mean ratio of percentage of helper T lymphocytes to that of suppressor Tlymphocytes in 39 patients with psoriasis are significantly increased as compared with that in 32 controls. 2, As classified into three groups according to extent of skin lesions (E: less than 5% E,: 5-30%, and E,: more than 30%), mean pereentages of total T lymphocytes in E, and E, psoriasis group and those of suppressor T lymphocytes in all three psoriasi., groups are significantly decreased as compared with those in controIs. Mean percentages of helper T lymphor,ytes in L psoriasis group and mean ratios of percentage of helper T lymphocytes to that of suppressor T lymphocytes in E, and E, psoriasis groups are significantly increased as compared with those in controls. 3. Cis classified into three groups according to activity of disease (A,: stationary, A,: active, peripherally spreading and A,: active, small papules spreading), mean percentage of total T lymphocytes in peripheral blood lymphocytes in A, psoriasis group and those of suppressor T lymphocytes in all three psoriasis group are significantly decreased as compared with those in controls. Mean percentages of helper T lymphocytes and mean ratios of percentage if helper T lymphocytes to that of suppressor T lymphocytes in A, and A, psorixsis groups are significantly increased as compared with those in controls. These results clarified that there are quantitative abnormalities in peripheral blood I' lymphocytes and T subsets in patients with psoriasis and the degrees of abnorrnalities are related to extent of skin lesions and activity of disease. The aanorrnalities in peri.pheral blood T lymphocytes and T subsets in patients with psoriasis seem to be attributed to primary defect of suppressor T lymphoytes.

BACKGROUND: A presumptive diagnosis of cutaneous tuberculosis can be made on the basis of patients' history, clinical and histologic findings. However, isolation of Mycobacerum tuberculosis is required for a definitive diagnosis and confirmation can be difficult with traditional techniques, including the direct visualization in tissue and growth in culture. OBJECTIVE: We used polymerase chain reaction(PCR) for the detection of mycobacterial DNA from routinely prepared formalin-fixed, paraffin-embedded skin specimens to evaluate its usefulness as a diagnostic tool. METHOD: We studied typical cases of localized cutaneous tuberculosis. Ten paraffin-embedded biopsy samples obtained from 2 patients with scrofuloderma, lupus vulgaris and tuberculosis verrucosa cutis were analyzed by PCR, respectively. RESULTS: M. tuerculosis DNA was demonstrated in all 10 specimens. CONCLUSION: This study shows that the PCR will be a useful method for the confirmation of the diagnosis in localized cutaneous tuberculosis and many skin lesions thought to be related to M. tuberculosis infection.

PURPOSE:We performed this study to compare correlation between the indices of insulin resistance using fasting insulin and glucose level and body mass index (BMI), and to determine the clinical usefulness of glucose/insulin ratio (G/I ratio), which is easily available in clinical base. METHODS:Total 119 children with simple obesity, whose BMI is over 95th percentile, were evaluated. We calculated G/I ratio, logInsulin, HOMA-IR, logHOMA-IR, and QUICKI and evaluated their relationship to BMI. RESULTS:Children with high-degree obesity had higher insulin resistance than children with mild to moderate-degree obesity (logInsulin, 1.13+/-.23 vs 1.27+/-.29; logHOMA-IR, 0.46+/-.24 vs 0.61+/-.30; QUICKI, 0.33+/-.03, 0.31+/-.03)(P<0.01), and pubertal children had higher insulin resistance than prepubertal children (G/I ratio, 7.39+/-.07 vs 4.85+/-.29; logInsulin, 1.14+/-.27 vs 1.31+/-.22; logHOMA-IR, 0.47+/-.28 vs 0.65+/-.22; QUICKI, 0.33+/-.03 vs 0.31+/-.02) (P<0.001). BMI had correlation coefficient as -0.436 for QUICKI, -0.432 for G/I ratio, 0.430 for logInsulin, and 0.425 for logHOMA-IR (P=0.000). G/I ratio was well correlated with QUICKI (r=0.901, P=0.000), logHOMA-IR (r=-0.865, P=0.000), and logInsulin (r=0.899, P=0.000). The changes of BMI were correlated with changes of G/I ratio (r=-0.547, P<0.01), QUICKI (r=-0.464, P=0.01), and logHOMA-IR (r=0.429, P<0.05). CONCLUSION: This study revealed that the degree of BMI had statistically significant correlation with insulin resistance, which can be reflected by G/I ratio, logHOMA-IR and QUICKI. G/I ratio was well correlated with logHOMA-IR and QUICKI, which suggests that G/I ratio could be used as an bedside index of insulin resistance. The changes of G/I ratio were more correlated with changes of BMI than those of logHOMA-IR and QUICKI.

INTRODUCTION: In this study, we compared sleep structure, EEG characteristic of pediatric obstructive sleep apnea (OSA) and normal controls which were matched in sex and age. METHODS: Fifteen children (male:female=4:11) who complained snoring and were suspected to have sleep apnea and their age and sex matched normal controls (male:female=5:10) have been done nocturnal polysomnography (NPSG). Sleep parameters, sleep apnea variables and relative spectral components of EEG from NPSG have been compared between both groups. RESULTS: Pediatric OSA group were distinguished from normal controls in terms of apnea index, respiratory disturbance index and nadir of oxyhemoglobulin desaturation. Pediatric OSA group showed increased percent of sleep stage 1, decreased rapid eye movement sleep percent and increased delta power in O1 EEG channel. However other sleep parameters and spectral powers were not different between two groups. CONCLUSION: In pediatric OSA group, sleep structure parameter disruption may be not prominent as the previous studies for adult OSA group because of including mild OSA data in diagnostic criteria. In addition, EEG changes might not be distinct due to low arousal index compared to adult OSA patients. We can observe general characteristics and particularity of pediatric OSA through this study.

The immunoreactivities of surgically removed 16 cardiac myxomas were studies for factor VIII-related Ag (F VIII-RA), Ulex europaeus agglutinin I (UEA-I) and desmin alpha1-antichymotrypsin, and this study was accompained by a clinicopathologic review. More than 50% of the patients with cardiac myxomas were in their fourth and fifth decades, and cardiac myxomas were much more common in women than in men. All but on occurred in the left atrium, and the majority were attached to the atrial septum, usually in the region corresponding to the fossa ovalis. In one case, an atrial myxoma recurred 37 months after the initial excision. Microscopically, the myxomas contained a myxoid matrix composed of acid mucopolysaccharides within which were embedded polygonal cells. The cells forming both the surface and complicated vascular like channels throuhout the myxoid stroma tested positive for F VIII-RA and UEA-I. The outer cell layers of the complex vascular structures demonstrated variable staining for F VIII-RA, while isolated bundles of smooth muscle cells were present and stained for desmin. A small number of the so-called myxoma cells, immunoreactive for alpha1-antichymotrypsin which were not laden with hemosiderin pigment but were similar to histiocytes, were present particularly around the areas of hemorrhage. These findings support the current view that cellular and histologic heterogeneity arose from the divergent differentiation of multipotential mesenchymal cells. In particular, it remains to be confirmed by further study whether or not true histiocytic differentiation occurs.
