BACKGROUND: A definition of granuloma is a focal chronic inflammatory response to tissue injury evolved by a poorly soluble substwice characterized by the accumulation and proliferation of the mono-nuclear histiocytic cells. The accuracy with which rnononuclear cells may be identified in skir. is much improved by the use of both heteroantisera and monoclonal antibodies directed against selected cellular antigens, OBJECTIVE: Our purpose was to examine the staining patterns of anti-lysozyme, anti-a-1-antitrypsin, anti-S-100 protein antibodies, and MAC-387 monoclonal anibody in granulomatous skin diseases. METHOD: We performed imminoperoxidase staining(the labelled str prvidin-biotin peroxidase complex method on the formalin-fixed, paraffin-embedded tissue specimens of granulomatous skin diseases. RESULTS: S-100 protein positive dendritic cells were demonstrated in the granulomatous infiltrates as scattered pattern and MAC-387 positive cells were predominantly found in the center of granulomas, The staining pattern and percentage of positively stained cells of a--antitrypsin were similar to those of lysozyme. A1Pha-1-antitrypsin and lysozyme positive cells w re present in the center as well as lymphohistiocytic infiltrates of granulomas. CONCLUSION: These data sugget that histiocytes are composed of heter igeneous groups of cells such as the mononuclear-phagocyte system and dendritic cell system.

PURPOSE: The aim of this study was to conduct a systematic review and to describe the characteristics of child abuse screening instruments. METHODS: Articles regarding the development of a child abuse screening instrument were investigated using the systematic review method. A literature search using the keywords "child and abuse or maltreatment and instrument or screening tool" in English, and "child," "abuse," and "instrument" in Korean, was conducted of material published in PubMed, PsycINFO, CINAHL, SCOPUS, ERIC, and RISS. Database and bibliographic searches, and quality appraisal using the Quality Assessment of Diagnostic Accuracy Studies tool that included systemic reviews, yielded 17 records. RESULTS: Key elementary child abuse screening instruments were developed for physical, psychiatric, affective and sexual and child neglect assessment. The instruments' target populations were children at home and in institutions. The reviewed instruments had the advantage of diagnosing past, concurrent, and indirectly, potential child abuse. CONCLUSION: The results of this study demonstrate that child abuse screening instruments are available for screening and for assessment of abused children in various circumstances. This review of child abuse screening instruments offers evidence for the acceptable use of optimal psychometric tools for child abuse assessment and provides guidelines for child health nursing practice.

BACKGROUND: Women sometimes have eyebrows tattooed for cosmetic purpose. But until recently, the removal of tattoos has been difficult. Several laser techniques have been proposed for the removal of tattoos. The lasers that have been used most successfully are the Q-switched systems because of their ability to target tattoo pigment selectively with minimal risk of adverse tissue response. OBJECTIVE: The objective of this study was to determine the clinical effectiveness of the newest Q-switched system, the alexandrite laser, in removing both eyebrow tattoos and to observe side effects such as scarring or permanent pigmentary changes. METHODS: Forty seven patients with both eyebrows tattooed were treated with the Q-switched alexandrite laser (755 nm, 100 ns) at eight week intervals and clinically evaluated.

Authors experienced a case of insulinoma which was initially misdiagnosed as idopathic temporal lobe epilepsy with automatism. This patients did not show other hypoglycemic symptoms except seizure. It has been reported that some of the patients with insulinoma are unaware of hypoglycemia and are at increased risk for seizures and coma. These patients would have normal glucose uptake in the brain and consequently no sympathoadrenal activation would begin, resulting in an awareness of hypoglycemia. It this case, abnomal EEG pattern consistent with a complex partial seizure remained after successful operation. Recent reports indicate that hypoglycemia is capable of killing neurons in the brain. An endogenous neurotoxin is produced and is released by the brain into tissue and cere-brospinal fluid. Endogenous excitotoxins produced during hypoglycemia may explain the tendency toward seizure activity often seen clinically. We suggest that persistent abnormalities of EEG in this case may be related to focal neuronal damage in hypoglycemia.

The estimation of age is an important issue in forensic science, and the forensic community has attempted many times to establish methods for solving this issue. Aging leads to alterations in tissues and organs at the molecular level. These alterations at the molecular level may aid forensic scientists to estimate the age of a living person or a dead body. Initially, the focus was on the genetic components of aging, but recently, epigenetic mechanisms have emerged as the key contributors to the alterations in genome structure and function that accompany aging. In particular, DNA methylation is one of the best-understood mechanisms, and it has been suggested as a promising biomarker for age estimation in many studies. In this review, we summarize the recent studies on age-associated DNA methylation changes in different tissues and discuss its possible and practical applications in forensics.

Condyloma acuminatum is a common viral disease which is transmitted by sexual intercourse. We experienced a case of condyloma acuminatum occurring in a patient of systemic lupus erythematosus who has been treated with various immunosuppressive agents for 10 years. This condylorna acuminatum was unusual in that it was very rapidly growing, recurrent and reluctant to various treatrnents. We investigated the type of human papillomavirus by Southern blot hybridization and schieved partial improvement by bleomycin intralesional injection together with 5-FU topical application.

PURPOSE: Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder with widespread manifestations that rarely include the eye. We present a case of SLE-associated choroidoretinopathy and secondary angle closure attack in both eyes. CASE SUMMARY: A 58-year-old male was admitted into the urologic department complaining of right scrotal swelling, and then consulted with the ophthalmology department regarding both ocular pain and eye injection. The patient was diagnosed with acute angle closure attack using a slit lamp test and tonometry secondary to choroidoretinitis with choroidal detachment at fundus examination in both eyes. The rheumatologist performed systemic evaluation, including serologic tests, and then diagnosed the patient with SLE. After systemic steroid therapy, intraocular pressure was decreased and choroidal detachment disappeared with improvements of choroidoretinitis in both eyes. CONCLUSIONS: Patients with systemic lupus erythematosus choroidopathy can develop secondary angle closure attack, which can be effectively treated using systemic steroid therapy and antiglaucoma drugs.

Leukemia is a rare disease in the newborn infant. We have presented an autopsy case of congenital acute myelocytic leukemia in a female neonate and discussecd with review of literature. At birth, she was relatively in good health with 4.2 kg in body weight except a large cephalhematoma on left parietal scalp and multiple subcutaneous nodules with ecchymosis on entire body surface. Hemoglobin concentration was 12.0 gm/, Hct 34.6% and erythrocyte count was 2.24 millions. Of 212,400 leukocytes/mm2, 47% were myeloblast. Biopsy of skin nodules reveal leukemia cutis, which disappear dramatically with anticancer drug. The infant was expired 12 days after admission due to intracerebral hemorrhage and acute renal failure.
