Palmoplantar pustulosis (PPP) often shows resistance to treatment. Vitamin D3 analog (VitD3) has been widely used for the treatment of psoriasis, however, the efficacy and safety of topical VitD3 ...treatment of PPP are not fully confirmed. Maxacalcitol topical ointment (22‐oxacalcitriol OCT) was applied twice daily for 8 weeks. Evaluation of efficacy was based on scored skin findings for three main symptoms (erythema, pustules/vesicles and keratinization/scales). The primary and secondary end‐points were the total and symptom‐specific scores of skin findings, respectively. A total of 188 patients with moderate or severe PPP were enrolled in the study and were randomized into either the OCT group (n = 95) or placebo group (n = 93). The total scores (mean ± standard error) of skin findings at the last observation adjusting for those on day 1 were 5.0 ± 0.20 in the OCT group and 6.9 ± 0.20 in the placebo group. There was a significant decrease in the total score of skin findings in the OCT group compared with the placebo group (P < 0.0001). In particular, the score of pustules/vesicles drastically decreased in the OCT group. In terms of safety, the incidence of adverse reactions in the OCT and placebo groups were 11.6% and 9.7%, respectively. These results indicate that OCT is effective and highly safe in the management of PPP. Topical OCT treatment was found to show a potent action on pustules/vesicles thereby contributing to the cure of PPP.

A survey of psoriasis patients from 1982–2001 has been reported by the Japanese Society for Psoriasis Research. The aim of this study is to analyze psoriasis patients in Japan registered from ...2002–2008. A total of 11 631 cases were registered from 152 dermatological institutions in Japan. Males (7738 cases, 66.5%) were predominant over females (3893 cases, 33.5%). The clinical types of psoriasis were psoriasis vulgaris (88.5%), guttate psoriasis (3.9%), psoriasis arthropathica (3.3%), generalized pustular psoriasis (1.3%), psoriatic erythroderma (1.2%), localized pustular psoriasis (0.9%) and infantile psoriasis (0.1%). Topical corticosteroids (85.4%) and vitamin D3 (59.7%) products were the main previous topical agents. Previous systemic treatments included etretinate (8.8%), cyclosporin (8.3%) and methotrexate (2.0%). Use of topical vitamin D3 and systemic cyclosporin therapies has been increasing during the past 7 years. Topical psoralen and ultraviolet A therapy (PUVA) (7.6%) was the predominant phototherapy followed by UV‐B (7.3%) and systemic PUVA (4.7%). Use of UV‐B phototherapy has been increasing during the past 5 years. The survey of Japanese psoriasis patients during 2002–2008 disclosed that psoriasis arthropathica is more prevalent (1%) than that of the previous survey during 1982–2001. Use of topical vitamin D3 and systemic cyclosporin has been increasing during the past 7 years.

To date, epidermoid cysts associated with human papillomavirus (HPV) infection have been described mainly in palmoplantar locations, and have involved HPV types 60 and 57. In contrast, HPV‐6/11 is a ...major cause of condyloma acuminatum. Here, we report the case of a healthy 31‐year‐old man who presented to our clinic with a 1‐month history of a 1‐cm, reddish‐brown, cystic scrotal tumor with a punctum. The lesion was studied histologically, immunohistochemically and by DNA–DNAin situ hybridization. Histology revealed an epidermoid cyst with vacuolated keratinocytes with shrunken nuclei (koilocytes) in the cyst wall. Immunostaining was positive for HPV antigens and in situ hybridization revealed HPV‐6/11 DNA in the koilocytes. This is the first report of an HPV‐6/11‐associated epidermoid cyst in the anogenital skin of an immunocompetent individual.

The number of elderly patients with psoriasis is increasing in Japan. However, biologic treatment is generally considered to be challenging in elderly patients, due to their increased risk of ...complications compared with younger patients. Our retrospective study aimed to evaluate the safety profile and efficacy of biologics in senior elderly patients (≥75 years old) with psoriasis. The study involved a cohort of 27 patients aged 75–88 years who were being treated with biologics over a period of more than 1 year. Initial biologics administrated to were adalimumab (five cases) and ustekinumab (22 cases). Eight patients discontinued treatment: two developed cancer; one was transferred to hospital; and five others experienced either bone fracture, interstitial pneumonia, cerebral hemorrhage resulting in death, decrepitude or developed hepatopathy following prophylactic tuberculosis treatment. Efficacy, evaluated by the percentage of patients achieving 75% reduction of Psoriasis Area and Severity Index score, was 76.9% at week 16 (n = 26), 88.0% at week 24 (n = 25) and 90.5% at week 52 (n = 21). Biologic treatments thus show clear efficacy in elderly patients with psoriasis, however, the increased frequency of adverse events requires rigorous patient observation.

Ustekinumab has demonstrated efficacy for psoriasis. However, it is known that approximately 30% of patients have shown insufficient response. The aim of the current study is to clarify the specific ...clinical factors that could be associated with response to ustekinumab treatment. We reviewed the medical records of all patients who were treated with ustekinumab. The Psoriasis Area and Severity Index (PASI) score was calculated, and the efficacy was evaluated at week 0 and week 16. The relationship between clinical efficacy and the patients’ background was investigated. The patients, who showed a <74% reduction in the PASI score, were classified as insufficient‐responders. A total of 74 patients (average 60.3 years old, male to female ratio 54:20) were examined retrospectively. Eighteen patients were identified as insufficient‐responders. Each of the factors, body weight (BW) over 80 kg, body mass index (BMI) over 25, or smoking habit over 20 cigarettes/day showed a higher proportion of insufficient‐responders compared with responders, although the difference was not statistically significant. Patients with previous exposure to biologics showed a significantly lower response to the treatment. Furthermore, a statistical difference was identified between patients with none of these factors and patients with some of these factors. Our data suggest that some factors, such as high BW, high BMI, a smoking habit over 20 cigarettes/day, or exposure previous treatment with biologics are likely to affect the quality of the response to ustekinumab. Therefore, these factors need to be taken into account when ustekinumab is administrated.

Clinically, patients' adherence to biologic treatment is not only related to efficacy but also to adverse events, cost and other factors. To evaluate long‐term viability of biologic treatment, both ...the percentage of and reasons for discontinuation of treatment were investigated. In this study, patients treated with infliximab (n = 38), adalimumab (n = 59) and ustekinumab (n = 30) were included and observed for 12 months. Clinical efficacy was evaluated using a 75% reduction of Psoriasis Area and Severity Index score (PASI‐75), and patients who discontinued treatment were considered as not having achieved PASI‐75. In addition, drug survival rate (DSR) was investigated. In patients treated with infliximab, PASI‐75 was 68.4% and DSR was 73.3% by the end of treatment. In patients treated with adalimumab, PASI‐75 was 50.8% and DSR was 79.7%. In patients treated with ustekinumab, PASI‐75 was 63.3% and DSR was 96.7%. Several patients discontinued treatment because of insufficient efficacy due to secondary failure in infliximab or primary failure in adalimumab. To increase treatment efficacy, it will be necessary for these patients to use an additional concomitant treatment. Higher efficacy is expected with biologics than with conventional treatments; however, the actual clinical efficacy over a long period of time may be insufficient if they are used without any concomitant treatments.

The safety and efficacy of topical E6005, a novel phosphodiesterase 4 inhibitor, in Japanese adults with atopic dermatitis were evaluated. A total of 78 patients were randomized to receive either the ...0.2% E6005 ointment or vehicle control (without E6005) at an allocation ratio of 2:1. The randomization phase of 4 weeks was followed by an extension phase of 8 weeks. In the extension phase, all 67 subjects who completed the randomization phase were treated with 0.2% E6005 ointment. The 4‐week application of topical E6005 twice daily was safe and well tolerated. The safety profile for up to 12 weeks was similar to that for the first 4 weeks. No deaths or other serious adverse effects were observed during the entire study period of 12 weeks. Plasma E6005 was undetectable in all subjects at all sampling points while very low plasma concentrations of an E6005 metabolite were detected in 47% of subjects receiving E6005 treatment. At the end of week 4, Eczema Area and Severity Index (EASI), Severity Scoring Atopic Dermatitis (SCORAD)‐objective, SCORAD‐C (visual analog scales for pruritus and sleep loss), itch Behavioral Rating Scale, and the severity of the targeted eczematous lesions in the topical E6005 group showed trends toward improvement compared with those in the vehicle group (not statistically significant). However, the group receiving topical E6005 for 12 weeks showed significant score reductions from baselines for EASI (P = 0.030), SCORAD‐objective (P < 0.001) and SCORAD‐C (P = 0.038). These results further support the development of topical E6005 for the treatment of atopic dermatitis.
