BACKGROUND: Dermal papilla cells, which are mesenchymal components of the hair bulb are considered to play an important role in the regulation of hair growth by production of diffusible factors that stimulate follicular epithelial cells. Degenerative changes in the dermal papilla cells in the involved scalp of alopecia areata cases indicate that these cells are one of the important targets in this disease. OBJECTIVE: We investigated the effects of serum from alopecia areata patients on the proliferation of dermal papilla cells. METHOD: Dermal papilla cells and fibroblasts from normal human scalp were cultured in DMEM media with 10% or 20% of normal and alopecia areata serum for 48hrs and 96hrs. Cell proliferation was measured by cell counts and [3H]-thymidine incorpoartion. RESULTS: Both 10% and 20% alopecia areata serum had no significant effects on the proliferation of dermal papilla cells and fibroblasts after 48hrs and 96hrs. CONCLUSION: These results suggest that there are no serum factors that inhibit the proliferation of dermal papilla cells.

BACKGROUND: This study purposed to survey the fit rate of respirators by person and by product through conducting a qualitative fit test of high-efficiency respirators; moreover, this study also tests for differences in the fit rates determined by the qualitative fit tests with an increase in the number of the types of respirators tested. METHODS: The subjects of this study were 30 healthcare personnel who had passed a sensitivity test. The fit test of high-efficiency respirators was conducted using FT10 (3M Co., USA), an experimental tool used for performing the qualitative fit test of high-efficiency respirators, and three types of high-efficiency respirators - 1860, PFR95, and N7000 - were tested. RESULTS: The qualitative fit test was performed for the three types of high-efficiency respirators and the fit rate of the respirators that the subjects had been using previously was 43.3%; however, the probability that one or more of the three types of high-efficiency respirators would fit the subjects increased to 83.3%, and this increase was statistically significant (P<0.05). The difference in the fit rates of the three types of high-efficiency respirator types was not statistically significant; however, the differences in the satisfaction of and preference for the different respirator products were all statistically significant (P<0.05). CONCLUSION: Healthcare personnel are using ill-fitting respirators and a qualitative fit test should be performed to improve the fit of their respirator. In the qualitative fit test performed for the high-efficiency respirators, the fit rate increased with the increase in the variety of respirator types. Thus, a large variety of respirators should be made available to increase the fit rate of high-efficiency respirators for healthcare personnel.

BACKGROUND: It was recognized that the intake of the whole cow's milk(WCM) early (before 1 year old of age) and large amount in early childhood is related to the iron deficiency, sometimes the iron deficiency anemia in advanced state. To verify the relationship between the variables in the WCM intake and the iron status, we carried out this study. METHODS: Thirty subjects(1 year to 3 years old of age) were classified as a WCM large intake group and a WCM small intake group. The relationship between the WCM commencing age and the iron status(serum ferritin, transferrin saturation and hemoglobin) in the WCM large intake group was evaluated and analyzed by the linear regression. Futhermore, the relationship between the value of WCM intake amountxduration/10 and the iron status(serum ferritin, transferrin saturation and hemoglobin) in the WCM large and small intake groups was evaluated and analyzed by the linear regression. RESULTS: As the WCM commencing age was earlier, the values of serum ferritin, transferrin saturation and hemoglobin decreased significantly(P<0.05). The values of serum ferritin and transferrin saturation decreased significantly as the value of WCM intake amountxduration/10 increased(P<0.05). But the value of hemoglobin decreased insignificantly as the value of WCM intake amountxduration/10 increased(P>0.1). CONCLUSION: The variables in the intake of WCM influence upon the iron status in early childhood. The early commencing of the WCM(before 1 year old of age) is the worst variable that influences adversely upon the iron status in early childhood. The amount of WCM intake and the duration influence upon the storage iron(serum ferritin and transferrin saturation), but not hemoglobin. In this regard, it is necessary to inform the parents of the correct WCM intake ways to avoid the irreversible recognition impairment and behavioral change.

Amyloidosis is a disorder of protein metabolism characterized by the extracellular deposition of abnormal protein fibrils. We report a case of macular amyloidosis due to nylon towel on his back. A 61-year-old male presented with asymptomatic hyperpigmented macules on the scapulae for 6 years. He had a habit of scrubbing his back for many years with a rough nylon towel while taking a bath. The histologic examination revealed liquefaction degeneration and homogenous eosinophilic deposition in the papillary dermis. In Congo red, amyloid material stained positively and in anti-keratin antibody staining. He had neither clinical nor laboratory evidence of systemic amyloidosis. A diagnosis of friction amyloidosis was made on histological and immunohistopathological findings.

Nodular scabies is a clinical variant of classic scabies with uncertain cause. The cutaneous manifestations consist of firm, erythematous nodules focally affecting genitalia, groin and axillae, and no case of generalized involvement has been reported in the literature. On histopathologic examination, mites and excretas were known to be seldom found in the stratum corneum, but if serial sections are studied, they can be seen in as much as 20% of the cases. The dermis shows dense superficial and deep perivascular mixed cell infiltration composed of lymphocytes, histiocytes, plasma cells, eosinophils, and atypical mononuclear cells, which should be distinguished from many types of lymphomas. We herein report a case of nodular scabies that clinically affected whole body and histopathologically revealed mite and eggshells in the stratum corneum and perivascular mixed cell infiltration throughout the dermis.

Kikuchi's disease(Histiocytic necrotizing lymphadenitis) is an idiopathic, self-limiting disease typically affecting cervical lymph nodes in young adults. Cutaneous involvement has been reported in 16-40%. We report a case of Kikuchi's disease in 10-year-old female that showed asymptomatic erythematous papules on the face accompanied by cervical lymphadenopathy. The histopathologic examination of the skin revealed diffuse dermal lymphohistiocytic infiltrate, a large amount of nuclear dust with absence of neutrophils, which is characteristic of Kikuchi's disease. In general, histopathologic findings of skin biopsy show a mirror image of that of lymph nodes involved in Kikuchi's disease. Therefore, it is important to recognize cutaneous manifestations of this entity, because we can avoid invasive lymph node biopsy. if skin lesions involved show typical histopathologic findings of Kikuchi's disease.
