The patient was a 13-year-old female. Six years previously, she developed alopecia areata when her parents divorced. One year after that, the bald area drastically expanded when her mother remarried. She was treated at her local hospital; however, no improvement was observed. She then visited our hospital for examination. A bald patch was covering >80% of her head. Self Grow-Up Egogram indicated the basic interpersonal relationship stance of 'I am not OK, You are OK'. We therefore implemented a transactional analysis approach to increase the patient's score on the Free Child subscale. New hair growth was observed after 6 months and the bald patch disappeared after 2 years. Our results suggest that this method could also be easily applied in a clinical setting by dermatologists.

A 13-year-old girl who had had pollinosis since the age of eight began to experience itching of the ears and vomiting after eating fresh fruits such as peach, apple and watermelon. This occurred at 10 years of age. The girl displayed positive reactions to six kinds of pollens, eleven kinds of fruits, numerous vegetables and to recombinant: rBet v2 present in specific IgE antibodies. She also reacted positively to several pollens, fruits and rBet v2 in the skin prick test. In the component-resolved diagnosis (CRD) using microarray technology, she also tested positive for profilin, a pan-allergen among plants. It is reported that profilin cross-reacts between pollen, fruits, vegetables and latex. From these results, we concluded that the allergic reactions to multiple kinds of foodstuff and pollens observed in this subject were due to cross-reactivity induced by profilin. Our results demonstrate that CRD by microarray is a reliable test in the diagnosis of PFAS.

We present a case of primary Epstein-Barr virus (EBV) infection with erythema multiforme. A 1-year-old Japanese boy presented with skin eruptions, including typical target lesions and a low-grade fever. Just before the skin biopsy, 95 copies/μg DNA of EBV genome was detected in peripheral blood mononuclear cells, which subsequently increased to 6,834 copies/μg DNA. Skin tissue collected from the skin lesion showed the typical pathologic findings of erythema multiforme. EBV-encoded small nuclear RNA signals were not detected in the skin tissue by in situ hybridization.

Drug rash with eosinophilia and systemic symptoms (DRESS), also known as drug-induced hypersensitivity syndrome (DIHS), is a severe adverse drug reaction affecting multiple organs caused by drug treatment. The current report describes a man who was prescribed zonisamide for epilepsy and subsequently developed widespread skin rash, acute kidney injury, high-grade fever, eosinophilia, liver dysfunction, lymphadenopathy and an increase in antihuman herpesvirus-6 immunoglobulin G titer. Hypersensitivity to zonisamide was confirmed by the skin patch test. Based on these findings, the patient was diagnosed with DRESS/DIHS caused by zonisamide. This is the first report of acute kidney injury due to zonisamide-induced DRESS/DIHS.

We report here a 76-year-old male that presented with an immediate allergy to Anisakis following saury intake. Three and a half hours after eating pressed saury sushi, whole-body pomphus appeared including itching, facial dropsical swelling, and dyspnea. Diagnostic tests revealed specific IgE antibodies against anisakis simplex and a skin prick test was positive using an extraction of anisakis simplex. The results of skin prick tests using the body and internal organs of a saury were negative. Based on these results, we diagnosed the case as immediate allergy to Anisakis. Anisakis is parasitic to a diverse array of fish, and it seems rare that eating saury will induce an allergic response because the reported parasitic rate of Anisakis on saury is only 5%. In addition, as tropomyosin is currently considered to be the primary cause of allergies to Anisakis, renewed attention should be paid to other foods for which tropomyosin is also assumed to be a common antigen.
