BACKGROUND: High-fat diet-induced obesity is one of the major cause of chronic renal failure. This obesity-related renal failure is mainly caused by inflammatory processes. However, the role of the major anti-inflammatory cytokine interleukin (IL)-10 has not been researched intensively. METHODS: To evaluate the effect of IL-10 deficiency on obesity-related renal failure, the in vivo study was carried with four animal groups; (1) Low-fat dieted C57BL/6 mice, (2) Low-fat dieted IL-10 knockout (KO) mice, (3) High-fat dieted C57BL/6 mice and (4) High-fat dieted IL-10 KO mice group. The analysis was carried with blood/urine chemistry, H&E, Oil-Red-O, periodic acid-Schiff and Masson’s trichrome staining immunohistochemistry and real-time PCR methods. RESULTS: At week 12, high-fat dieted IL-10 KO mice showed 1) severe lipid accumulation in kidneys, cholesterol elevation (in total, serum kidney) and low-density lipoprotein increasion through the SCAP-SREBP2-LDLr pathway; (2) serious histopathologic alterations showing glomerulosclerosis, tubulointerstitial fibrosis and immune cell infiltration; (3) increased pro-inflammatory cytokines and chemokines expression; (4) enhanced renal fibrosis; and (5) serious functional failure with high serum creatinine and BUN and proteinuria excretion compared to other groups. CONCLUSION IL-10 deficiency aggravates renal inflammation, fibrosis and functional failure in high-fat dieted obese mice, thus IL-10 therapy could be applied to obesity-related chronic renal failure.

Vitiligo and morphea are two distinct entities of unknown etiology, although their existence implies that the immune system and/or the central or peripheral nervous system has been incriminated. Only a few reports of their simultaneous occurrence are on record. Here we report a case of a 39 year old woman affected with both vitiligo of the face, chest and hand and morphea of shoulder and trunk. Since the two diseases appeared after bone marrow transplantation, if could be deduced that there is a possible association between them. Two diseases observed simultaneously in this patient may be derived from the common pathomechanism. An autoimmune etiology is thought to play a part in both of these diseases.

Chrome may have a corrosive, necrotizing effect on tissue, so repeated skin contact to chromate might induce perforations or ulcers on the skin. This condition is called a "chrome ulcer" or "chrome hole". It appears as a small, punched-out mark with a rolled-out border. It is rarely associated with pain, but a severe itching sensation is common. We report a case of a 33-year-old man who presented with a 3 month history of several ulcers on his abdomen. He was employed at a chromate alloying process. He had several hole-like atrophic scars and unbearable pruritus. After changing his occupation, plus treatment with oral corticosteroids and antihistamines, the lesions were healed and the itching sensation faded away. However, atrophic scarring remained.

Chronic exogenous steroid therapy can result in hypothalamic-pituitary-adrenal axis dysfunction; this usually results from systemic steroid therapy, and is rarely associated with topical steroid therapy. We report a case of suspected iatrogenic Cushing syndrome that developed after the treatment of annular pustular psoriasis. The patient applied clobetasol-17-propionate cream (Betabate(R)) 15~30 g daily, for 4 months, without a dermatologist's prescription. After 4 months of application, the following symptoms developed; a moon face; facial flushing; hypertrichosis; central obesity; purple striae; and multiple erythematous scaly annular patches. The development of Cushing syndrome from exogenous corticosteroid treatment was supported by the typical clinical manifestations and the low basal state of the blood cortisol level, which was perhaps due to secondary suppression of the hypothalamic pituitary-adrenal axis. Steroid-containing drugs, especially during childhood, should be used with caution and monitored carefully.

Reed's syndrome is a rare, autosomal dominant disease with incomplete penetrance that is characterized by uterine and cutaneous leiomyomas. We report a case of Reed's syndrome in a 50-year-old woman. The patient underwent removal of the uterine leiomyoma at the age of 36. Following this the patient noticed development of multiple, cutaneous nodules on both arms at the age of 45. These nodules progressively increased in both number and size, while appearing in other sites. The histopathologic finding of an isolated, single skin lesion showed typical leiomyoma arising from arrector pilorum muscle. Familial history revealed that her father had been affected with similar cutaneous lesions.

Sebaceous hyperplasia can occur on the face during middle age, particularly in men. The risk of sebaceous hyperplasia is significantly increased in adult transplant patients, particularly males, following renal transplantation, and this is related to therapy with cyclosporine. We report on 2 cases of sebaceous hyperplasia in renal transplant patients who were treated with cyclosporine. The condition was improved, without scarring, by treatment with carbon dioxide laser or cryotherapy.

Eczema herpeticum is a herpes simplex virus infection with disseminated skin involvement, which superimposes on a pre-existing dermatosis. Two siblings with simultaneous primary herpes simplex virus (HSV) infection on the normal skin of their backs, followed by their mother's herpes labialis. Eczema herpeticum was diagnosed on the basis of history, clinical feature, Tzanck test, histologic examination and a serologic test. Their skin lesions were healed by treatment with oral acyclovir and mupirocin ointment.

BACKGROUND: Pain and paresthesia often precede the eruption of herpes zoster and vary from itching to stabbing. The preeruptive pain may simulate other diseases and may lead to misdiagnosis and misdirected interventions. OBJECTIVE: The aim of this study was to elucidate the clinical characteristics of herpes zoster and its nature of pain. METHODS: Three hundred and thirty three patients who were admitted with herpes zoster during a 10-year period from 1995 to 2004 were evaluated in regard to age, sex, dermatomal distribution, associated diseases, and complications. Patients were further assessed concerning the nature of the pain and its relationship to age, sex, dermatomal distribution, and postherpetic neuralgia. RESULTS: Herpes zoster was seen most frequently in the 70~79 year-old age group (30.9%), and the ratio of male to female patients was 1 : 2.2. The most common dermatomal distribution was thoracic dermatome (39.6%), followed by trigeminal (30.9%), cervical (11.7%), lumbar (7.2%), sacral (2.7%), and multiple dermatomal involvement (4.5%). Associated diseases to herpes zoster were observed in 180 patients (54.1%) which included hypertension (18.6%), diabetes mellitus (8.7%), gastritis and gastric ulcer (6.0%), fatty liver and hepatitis (5.1%), pulmonary tuberculosis (3.3%), malignancy (2.7%), rheumatoid arthritis (1.8%), and various other conditions (7.9%). The most common complication of herpes zoster was postherpetic neuralgia (15.6%), followed by ocular complications (6.9%), secondary infection (1.5%), scar formation (0.9%), Ramsay-Hunt syndrome (0.6%), and a neurogenic bladder (0.3%). The most common nature of pain associated with herpes zoster was pricking or stabbing (68%), followed by a dull ache (8.1%), tingling (7.2%), burning (4.2%), numbness (3.9%), throbbing (2.1%), a water trickling sensation (1.5%), itching (1.5%), formication (1.2%), soreness (0.9%), bursting (0.6%), sensation of being pulled down (0.3%), and sensation of cold water being poured on the skin (0.3%). Paresthesia was observed in 11 patients (3.3%), and 8 of these complained of this in the trigeminal dermatome (72.7%). CONCLUSION: Higher incidences of herpes zoster were observed in female and in the 70~79 year-old age group. The nature of pain associated with herpes zoster varied from a superficial itching to severe stabbing or bursting, and paresthesia occurred most frequently in the trigeminal dermatome.

Mutiple cutaneous reticulohistiocytosis represent a unique pattern in the spectrum of reticulohistiocytoses, and are characterized by multiple granulomas confined to the skin without evidence of arthritis or underlying systemic illness. We report a case of multiple cutaneous reticulohistiocytosis in a 31-year-old male, who presented with multiple, asymptomatic reddish-brown or skin-colored papules on the whole body. Histopathologically, there were numerous mononuclear and multinucleated histiocytes with a ground glass appearance in the dermis. The histiocytes were diastase-resistant, and periodic acid-Schiff reagent and CD 68 positive. The patient was treated with narrow band UVB for 1 month and slightly improved slightly.
