RESUMO
Corticosteroids are potent anti-inflammatory and anti-allergic agents used in the treatment of various inflammatory diseases, including allergic disease. They are frequently considered the therapy-of-choice for many skin diseases. However, allergic reactions caused by corticosteroids have been reported. Among these, delayed reactions to topical steroids are more common, whereas immediate reactions to systemic steroids are rare. Herein, we report the case of a 32-year-old woman with triamcinolone-induced immediate hypersensitivity reaction, in which the patient had a positive prick test result with triamcinolone. She has had atopic dermatitis (AD) for three years. She had used systemic steroid, cyclosporine, and antihistamine with topical steroids for AD. In clinic, approximately 10 minutes after intralesional injection of triamcinolone, she complained of erythematous patches with slight elevation and itching on the face, trunk, and both hands. After intravenous injection of dexamethasone, her symptoms got worse. After treatment with epinephrine, all symptoms resolved within two hours. We performed an open test and skin prick test. She had a positive result only from the prick test with triamcinolone; all other steroids showed negative results from the open tests. Dermatologists should be aware of the possibility of anaphylaxis or other allergic hypersensitivity in response to corticosteroids.

Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus that can cause permanent scarring. Treatment of DLE includes protection from sunlight and artificial sources of ultraviolet light, as well as systemic and topical medications. The first-line standard therapies are antimalarials and topical steroids. Other systemic therapies include systemic steroid, azathioprine, dapsone, and immunosuppressive agents. Topical tacrolimus and pimecrolimus have also been evaluated. Recent studies reported that several treatments, including pulsed dye laser, CO₂ laser, intense pulsed light (IPL), and 1,064-nm long-pulse neodymium-doped yttrium aluminum (Nd:YAG) have been used for the cosmetic treatment of DLE. Here, we report a case of a DLE scar that was successfully treated with a combination therapy of IPL and Q-switched 1,064-nm Nd:YAG laser.

BACKGROUND: Histamine in food is known to cause food poisoning and allergic reactions. We usually ingest histamine in cooked food, but there are few studies about the influence of cooking method on the histamine level. OBJECTIVE: The purpose of this study was to determine the influence of cooking methods on the concentration of histamine in foods. METHODS: The foods chosen were those kinds consumed frequently and cooked by grilling, boiling, and frying. The histamine level of the food was measured using enzyme-linked immunosorbent assay. RESULTS: Grilled seafood had higher histamine levels than raw or boiled seafood. For meat, grilling increased the histamine level, whereas boiling decreased it. For eggs, there was not much difference in histamine level according to cooking method. Fried vegetables had higher histamine levels than raw vegetables. And fermented foods didn't show much difference in histamine level after being boiled. CONCLUSION: The histamine level in food has changed according to the cooking method used to prepare it. Frying and grilling increased histamine level in foods, whereas boiling had little influence or even decreased it. The boiling method might be helpful to control the effect of histamine in histamine-sensitive or susceptible patients, compared with frying and grilling.

BACKGROUND: It has been reported that heat shock protein 70 (HSP70) and interleukin-8 (IL-8) play an important role in cells during the wound healing process. However, there has been no report on the effect of HSP70 and IL-8 on the blisters of burn patients. OBJECTIVE: This study aimed to evaluate the serial quantitative changes of HSP70 and IL-8 in burn blisters. METHODS: Twenty-five burn patients were included, for a total of 36 cases: twenty cases on the first day, six cases on the second, five cases on the third, three cases on the fourth, and two cases on the fifth. A correlation analysis was performed to determine the relationship between the concentration of HSP70 and IL-8 and the length of the treatment period. RESULTS: The HSP70 concentration was the highest on the first day, after which it decreased down to near zero. Most HSP70 was generated during the first 12 hours after the burn accident. There was no correlation between the concentration of HSP70 on the first day and the length of the treatment period. No measurable concentration of IL-8 was detected before 5 hours, but the concentration started to increase after 11 hours. The peak value was measured on the fourth day. CONCLUSION: While HSP70 increased in the first few hours and decreased afterwards, IL-8 was produced after 11 hours and increased afterward in burn blister fluid. These findings provide new evidence on serial changes of inflammatory mediators in burn blister fluid.

RESUMO
Atypical mycobacteria, widely distributed in nature, are opportunistic infection strain, rare pathogen in immunocompetent patients. Recently, the increase of invasive cosmetic treatment and surgery has increased the infection of atypical mycobacteria. We report a case of cutaneous infection by Mycobacterium fortuitum and Mycobacterium intracellulare that occurred after a fat graft. A 62-year-old female patient presented painful, erythematous nodules and purulent discharge on her face after a fat graft. A skin biopsy and culture were performed. Polymerase chain reaction-hybridization to identify mycobacterium other than tuberculosis revealed M. fortuitum and M. intracellulare. The patient was treated with clarithromycin, rifampicin, and ethambutol for 1 month after excision and drainage of pus, after which the skin lesions improved. In cases of refractory cutaneous infection after an invasive cosmetic procedure, atypical mycobacterial infection should be suspected.

BACKGROUND: The etiology of chronic urticaria (CU) remains unknown in most patients. Possible causes in some cases include food, but the role of allergy to food antigens in patients with CU remains controversial. OBJECTIVE: The aim of this study was to evaluate the association between food allergy and CU. METHODS: Korean patients with CU were assessed for a previous history of food allergy that caused symptoms of CU. Blood samples were taken from 350 patients to measure food allergen-specific IgE. Based on history and laboratory results, open oral food challenge (OFC) tests were performed. RESULTS: Of 350 participants, 46 (13.1%) claimed to have experienced previous food hypersensitivity. Pork (n=16) was the main food mentioned, followed by beef (n=7), shrimp (n=6), and mackerel (n=6). We found that 73 participants (20.9%) had elevated levels of food-specific IgE, with pork (n=30), wheat (n=25), and beef (n=23) being the most common. However, when the open OFC tests were conducted in 102 participants with self-reported food hypersensitivity or raised levels of food-specific IgE, only four participants showed a positive reaction to pork (n=3) or crab (n=1). CONCLUSION: Although some participants claimed to have a history of CU related to food intake, when an open OFC test was conducted, few of them had positive results. We therefore conclude that food allergy is an uncommon cause of chronic CU.

BACKGROUND: Pork is one of the most widely consumed meats in Korea. With increased consumption of pork, it has become one of the most common causes of food allergy in Korea. However, actual data on the prevalence of pork allergy in Korea are limited. OBJECTIVE: The aim of this study was to estimate the prevalence of pork allergy in Korea. METHODS: The outpatient attendees of the dermatology department of Kangnam Sacred Heart Hospital were randomly screened and assessed for a self-reported history of pork allergy through face-to-face interviews and self-administered questionnaires. Blood samples were taken from the patients to measure serum pork-specific IgE. Based on their history and laboratory results, patients were further examined by skin prick test (SPT) and open oral food challenge (OFC) tests. RESULTS: Five-hundred participants answered the screening questionnaire. Among all participants, nine (1.8%) participants claimed to have experienced adverse reactions to pork previously. Among 100 participants who underwent blood sampling, five (5%) participants had elevated level of serum IgE specific to pork. However, among nine participants with self-reported pork allergy, two participants (0.22%) showed a positive reaction on the open OFC test. CONCLUSION: Some participants claimed to have a history of adverse reaction related to pork intake; however, few of them showed positive results in allergy tests. We therefore conclude that the prevalence of pork allergy is extremely low in Korea.
