  • Dioxins refer to a family of chemicals comprising 75 polychlorinated dibenzo-p-dioxin (PCDD) and 135 polychlorinated dibenzo-p-furan (PCDF) congeners, which may cause skin disorder, human immune system disruption, birth defects, severe hormonal imbalance, and cancer. The effects of exposure of dioxin-like compounds such as PCBs are mediated by binding to the aryl hydrocarbon receptor (AHR), which is a ligand-activated transcription factor. To grasp physicochemical factors affecting human toxicity of dioxins, six geometrical and topological indices, eleven thermodynamic variables, and quantum mechanical descriptors including ESP (electrostatic potential) were analyzed using QSAR and semi-empirical AM1 method. Planar dioxins with high lipophilicity and large surface tension show the probability that negative electrostatic potential in the lateral oxygen may make hydrogen bonding with DNA bases to be a carcinogen.

  • During the screening program to discover antiatopic agents from herbal formulas, we investigated the inhibitory effect of Hwangryunhaedoktang (HT) on passive cutaneous anaphylaxis and oxazolone-induced mouse ear dermatitis. HT significantly inhibited PCA reaction in mice at doses of 50 and 200 mg/kg with inhibitory activity of 31 and 53%, respectively. HT at concentration of 0.05 and 0.1% inhibited ear swelling by 23 and 46% at 16 days in oxazolone-induced mouse ear dermatitis. Both HT with anti without human intestinal microflora showed potent inhibitory activity on the ${\beta}$-hexosaminidase release induced by IgE. Based on these findings, HT may be a usable agent for skin disorder contact dermatitis.

  • Sweet's syndrome also known as acute neutrophilic dermatosis is a multisystem inflammatory disorder characterized by fever, malaise, leukocytosis, and skin lesions. Sweet's syndrome affects multiple organs though only rarely does it affect the central nervous system (CNS) when it does it is called Neuro-Sweet disease (NSD). We report on a case study of a biopsy-proven NSD in a 50 year old man. Serial magnetic resonance imaging (MRI) showed repeated CNS involvement of Sweet's syndrome after a respiratory tract infection preceded it. On the MRI, T2 hyperintense lesions occurred at multiple sites and disappeared after steroid therapy.

  • Psoriasis is a common, chronic, recurrent, immune-mediated inflammatory disorder of skin. Although conventional topical and systemic therapies yield remission for a while, they carry a risk of many side effects that limit the long term use of these agents and the disease recurs generally in a short period of time after cessation of therapy. An increasing number of psoriatic patients are using herbal products as a treatment to control their disease with less side effects. Clinicians should be aware of plants used in psoriasis and side effects related with them. The aim of this article is to review the different herbs used in psoriasis treatment.

  • Molluscum contagiosum(MC) is a viral disorder of the skin and mucous membranes characterized by decrete single or multiple, flesh-colored papules. There was the 6 years old woman who suffered from umbilicated papules and pruritis of back. First, Her mother choiced western medicine, and was treatded with topical(ointment applicatoin) and surgical(curettage) method. Despite of western medical treatment during 3 months, there was not recovery of symptoms. So, she visited the Dept. of Opthalmology & Otorhinolaryngology & Dermatology, College of Oriental Medicine, Kyungwon University for oriental medical treatment. The oriental medical treatment reduced the symptoms of the patient remarkably during 8weeks. So we report the healing process and result of this patient in this study. There is few report that treat MC with oriental medical method. If more clinical trials like this are proved to be effective, we can expect that oriental medical treatment will be a good method in MC.

  • Parry Romberg Syndrome (PRS), also known as idiopathic progressive hemifacial atrophy, is a rare neurocutaneous disorder characterized by loss of skin and subcutaneous fat of face, muscles, and bones causing unilateral atrophy. Most patients require only soft tissue augmentation although syndrome has varying grades of severity. In the majority of reported cases, it has been treated with surgical flap or autologous fat transplantation. However, these treatments need complicated surgical skills which take a lot of time and cost. Herein we report the first case of PRS augmented by hyaluronic acid (HA) filler in a 42-year-old female patient to suggest that HA filler could be a safe, simple, and even rational economic alternative to surgical treatment.

  • Behçet's disease (BD) is a systemic immunological disorder characterized by recurrent mucosal ulcerative lesions including oral and genital ulcerations in association with skin and ocular involvements. BD also can involve the gastrointestinal tract. Gastrointestinal involvement of BD is one of the major causes of morbidity and mortality for this disease. However, clinical data are quite limited because of the rarity of intestinal BD. Therefore, the management of intestinal BD is heavily dependent on expert opinions and standardized medical treatments of intestinal BD are yet to be established. In this brief review, the authors summarized the currently available medical treatments such as 5-aminosalicylic acids, corticosteroids, immuno-modulators, and anti-TNF agents. Moreover, we sought to suggest a treatment algorithm for intestinal BD based on the recently published and updated data.

  • Aplasia cutis congenita (ACC) is a rare congenital disorder characterized by skin defects involving the epidermis, dermis, subcutaneous tissue, bone, and sometimes dura. It commonly affects the scalp in approximately 70% of cases, but the neck, trunk, and the extremities can also be affected. ACC can occur either as an isolated condition or associated with other anomalies and congenital syndromes, and it can be acquired either genetically or sporadically. Morbidity and mortality are associated with the defects of skull bone, dura, and other multiple anomalies. We herein report the case of a female infant, with a large scalp defect accompanied by a skull defect noted at birth, who developed mental retardation in the preschool years.

  • Disseminated superficial actinic porokeratosis (DSAP) is a rare keratinization disorder. It is histopathologically characterized by the presence of coronoid lamellae and clinically by lesions showing central atrophy with elevated borders. Squamous cell carcinoma originating in the classical Mibelli subtype of porokeratosis is well-documented; however, few reports have described squamous cell carcinoma in DSAP lesions. We report the case of a 76-year-old woman with DSAP who developed Bowen's disease, actinic keratosis, and keratoacanthoma on her face.

  • Subcorneal pustular dermatosis (SPD) is a rare pustular skin disorder of dogs. Dapsone is treatment of choice, but ineffective in some cases. Therapeutic alternatives are limited and less effective. In humans, successful results with oral retinoid have been reported. To describe successful treatment of a dog that developed SPD with acitretin as an alternative drug of dapsone. A 7-year-old male neutered miniature schnauzer was presented with generalized pustules and crusts. SPD was diagnosed based on physical, cytological, and histopathological examination with direct immunofluorescence test. In this report, we describe a case of canine SPD treated initially by dapsone with poor response that improved with acitretin. Acitretin could be considered as an alternative drug in canine SPD.
