PURPOSE: Recently, two tests are commercially available for the identification of latent tuberculosis infection (LTBI): tuberculin skin test (TST) and interferon-gamma release assay (IGRA). Due to its false positiveness, TST tends to be preferred by IGRA until now. In our study, we simultaneously performed both TST and QuantiFERON(R)-TB Gold In-Tube (QFT-GIT) and compared their results. METHODS: TST and QFT-GIT were done for the diagnosis of LTBI among children who visited pediatric out-patient clinic at St. Vincent's Hospital, The Catholic University of Korea from February of 2007 to May of 2008. The study group was stratified into two groups in terms of whether there was intrafamilial contact or not. RESULTS: Out of total 35 children, 29 were tuberculosis (TB)-exposed cases and the remainders were diagnosed as clinical pulmonary TB. Among these 29 children, TST was positive 38.9% (7/18) for the intrafamilial and 45.5% (5/11) for the non-intrafamilial, and at the same time, the result for QFT-GIT was positive 5.6% (1/18) and 9.1% (1/11), respectively which implies that TST was more sensitive than QFT-GIT. Among 29 TB-exposed cases, 26 initially went through TST and QFT-GIT together on their first visit to out-patient clinic, and 15 continued the follow-up tests. Out of total 41 cases collected, the agreement (known as kappa value) was 0.063 which was relatively low. Including 6 cases with pulmonary TB who were all positive for TST and only 5 being positive for QFT-GIT, the final kappa value was 0.334. CONCLUSION: In our study, the agreement for TST and QFT-GIT was low, and the majorities were almost the cases of positive TST. In current situation with lacking a gold standard test and limited data on children to adolescents, this result is quite alarming that the recent trend tends to replace TST by QFT-GIT when diagnosing LTBI.

Spinal dysraphism, first described by Lichtenstein in 1940, is a congenital anom- aly due to incomplete fusion or malformation of the midline dorsal embryonic structures including the ectoderm, mesoderm, and neuroectoderm. Spina bifida occulta is a spinal dystraphism and a manifestation of a midline defect of osseous spine and related structures without cyst formation. Spinal dysraphism may be associated with hypertrichosis, lipoma, dimpling, pigmentation, hemangioma, congenital scar, sinus, cyst, or skin defect in the midline dorsal area. We observed a 23-year-old female patient with spina bifida occulta who had a blue scar surrounded by circumscribed hair growth of the lumbosacral area since 1-montb-old age. Histopathologic finding of the blue scar revealed common blue nevus showing intradermal melanocytes and melanophages. Spine X-ray showed hemivertebra of L5 and spina bifida occulta of Sl. There were no abnormal neurologic signs.

It is generally recognized that several chemical mediators are involved in tbe pathogenesis of sunbum; however, the exact mechanism is still to he resolved. Recently, prostaglandin has been found to be one of the inflammatory mediators in sunbum, particularly in the delayed erythema response and several investigators have shown that the nonsteroidal antiinflammatory drugs inhibit the in vivo synthesis of prostaglandin. On the assumption that the nonsteroidal antiinflammatory drugs might exert a beneficial effect on the sunbum through the antiprostaglandin effect, several authors have reported the effect of indomethacin on sunbum. This study was undertaken to evaluate the effect of topical indomethacin on the delayed erythema response induced by artificial sunlamp and sunlight by clinical and histopathological examination. Indomethacin(2. 5% ointment, 2. 5% solution, 5% solution) was applied immediately after 3 MED irradiation of artificial sunlamp to the shaved back skin of 6 healthy albino guinea pigs weighing 550-850gm and 9 human volunteers and the delayed erythema response was observed at 2, 4, 6, 12, 24 and 48 hours after irradiation respectively. Punch biopsies of the skin were performed on 6 guinea pigs at 6, 12, 24 a.nd 48 hours after irradiation and the histologic changes were observed. Four human volunters were exposed t,o 3 MED of sunlight and indomethacin preparations were applied immediately after irradiation. The delayed erythema response was observed at 2, 4, 6, 12, 24 and 48 hours postirradiation and in one volunteer, the skin was biopsied at 24 hour for histologi.c evaluation. The results were as follows: 1. Topical indomethacin in ointment or solution forms delayed and decreased the appearance and degree of erythema induced by sunlight and artificial sunlamp in both human and animal subjects. 2. Histologically, the number of sunbum cells at 24 hour in the epidermis of one human volunteer was decreased on indomethacin applied sites. The dermis showe6 no difference in histologic changes between control and indomethacin sitea. In animal study, however, no detectable difference in epidermal or dermal changes was observed between control and indomethacin applied sites. The autors confirmed that topical indometha,cin was effective in delaying and blanching of the delayed erythema of sunbum in guinea pigs as well as in human volunteers, though there was no difference in histologic changes between indomethacin and control sites in guinea pigs. The mechanism involvel on this aspect is remained to be resolved.

The association rate of antibody with antigen has been reported to be greatly increased by lowering ionic strength. Low-ionic strength salt solution(LISS) method has been used for the detection of various alloantibodies. To investigate the sensitivity of LISS in indirect antiglobulin test, a comparison study of LISS with saline and albumin methods was conducted. A total of 32 patients' samples requested for indirect antiglobulin test were evaluated. Out of 32 patients with clinical immune hemolytic anemia, 11(34.3%) were positive in 37 degrees C saline antiglobulin test, 18(56.2%) in albumin antiglobulin test, 23(71.8%) in LISS antiglobulin test respectively. These results were statistically analyzed using non parametric Page's test for ordered alternatives. LISS method is more sensitive than 37 degrees C saline method or albumin method significantly (p<0.01).

We report a case of multiple Bowen's disease associated with leprosy. A 68-year-old man was seen because of slightly pruritic multiple erythematous scaly patches and plaques on the trunk and the both extremities for 5 years. He has been treated for leprosy with many kinds of drugs consisting of the herb medications for over 40 years. He also showed decreased cell-mediated immunity in skin tests. It is considered that depressed cellular immunity may be an important predisposing factor in the development of mutiple Bowen's disease in this case, .although arsenics can not be completetly excluded.

A 31-year-old woman had a livedo reticularis of reticulated, bluish discoloration on both arms and legs for 18 months with a burning pain in the right hand and numbness in both lower legs. The findings of the electromyography were consistent with mononeuropathy multiplex and bilateral ulnar-median nerve anastomosis. A biopsy specimen from the right sural nerve showed perivascular lymphocytic infiltration and occasional myelin digestion chambers, which were consistent with vasculitic neuropathy. We present a patient with livedo reticularis idiopathica associated with mononeuropathy multiplex syndrome who also has bilateral ulnar-median nerve anastomosis.
