ABSTRACT

BACKGROUND: The use of potassium iodide (KI) to treat palmoplantar pustulosis (PPP) and pustulotic arthro-osteitis (PAO) has not previously been reported. Here, we report the first successful treatment of PPP and PAO with KI. PATIENT AND METHODS: Among 25 patients with PPP, seven had an associated PAO. All patients were administered 900 mg KI three times per day for 3 months. Overall, 12 patients received this medical treatment for the first time or had >6 months interval since the last therapy for PPP. The other 13 patients who were nonresponsive to tetracycline for >3 months prior to KI treatment were treated with a combination of KI and tetracycline. All seven patients with PAO were included in the tetracycline and KI-treated group. RESULTS: More than 70% of patients demonstrated complete clearance or ≥50% improvement in palmoplantar pustular psoriasis area and severity index (PPPASI) from baseline. In the group with <50% improvement in PPPASI from baseline, all except one patient were smokers. In the KI with tetracycline treatment group, approximately 80% demonstrated improvement. At the end of 3 months, there was remission of arthralgia in five out of seven PPP patients with PAO. CONCLUSIONS: Treatment with KI and/or its combination with tetracycline may be a useful treatment for PPP/PAO. Smoking may affect the effectiveness of these treatment modalities.

ABSTRACT

BACKGROUND/OBJECTIVES: Developmental changes of structures in neonatal and infant skin have not been well characterized. The purpose of this study was to clarify changes in skin structures during neonatal and infant growth in vivo. METHODS: Fifteen healthy, full-term neonates (seven girls, eight boys) were studied. The measurements were performed 4 to 7 days (neonate) and 1, 3, and 6 months after birth on the buttock, upper thigh, and ventral forearm skin using a confocal laser scanning microscope. Developmental changes in dermoepidermal junction structures, stratum corneum thickness, epidermal thickness, and microvascular development were investigated. RESULTS: A significant decrease in stratum corneum thickness was observed over the 3 months after birth. Dermal papillae were not observed in neonatal skin but were observed gradually over the next 3 months. Epidermal thickness, determined from the skin surface to the bottom of the epidermal layer, increased significantly from 4 to 7 days to 1 month of age, indicating the formation of dermal papillae and rete ridges. Complicated microvascular structures were observed in neonatal skin but disappeared gradually and were observed only at the dermal papillae at 3 months of age. CONCLUSIONS: Our results reveal that infant skin is in a developmental stage structurally up to 3 months of age, paralleling skin functional and developmental maturation.

ABSTRACT

A 57-year-old Japanese male patient with an 18-year history of discoid lupus erythematosus (DLE) presented with alopecia on his scalp, and was clinically diagnosed to have alopecia areata. He was started on topical immunotherapy with squaric acid dibutylester (SADBE) for the treatment of alopecia areata. The patient was first sensitized with the application of 2% SADBE on the right upper arm, followed subsequently by re-exposure to a low concentration of SADBE to provoke contact dermatitis on the scalp as treatment. Approximately 2 months later, he developed multiple red scaly lesions on his scalp and face, which were diagnosed histopathologically as DLE. DLE is known to be exacerbated by a variety of factors, including sunlight, X-rays, tattoos, burns, and some forms of cutaneous trauma, including dermatitis. However, to the best of our knowledge, there have only been two reported cases of DLE exacerbated by contact dermatitis.
