Incontinentia Pigmenti: Clinical Observation of 40 Korean Cases

Incontinentia pigmenti (IP) is an uncommon genodermatosis that usually occurs in female infants. It is characterized by ectodermal, mesodermal, neurological, ocular, and dental manifestations. The aim of this study was to clarify clinical symptoms, accompanying diseases, and complications of IP. Forty cases of IP have been reviewed by their medical records, laboratory data, clinical photographs, and telephone survey. Male-to-female ratio was 1 to 19 and their onsets were mostly in utero. They were usually diagnosed during the neonatal period owing to their early expression of skin manifestation. Central nervous system anomalies were found in 46.7%. Ocular disorders and dental defects were detected in 66.7% and 72.7% respectively. The most commonly diagnosed anomalies were hypodontia, retinopathy, and seizure. For better understanding of IP, long term and close cooperation between dermatologists, pediatricians, neuroscientists, genentic counselors, and even dentists is crucial.

Efficacy of 5% Minoxidil versus Combined 5% Minoxidil and 0.01% Tretinoin for Male Pattern Hair Loss A Randomized, Double-Blind, Comparative Clinical Trial

AbstractBackground: 5% topical minoxidil solution has been widely used to stimulate new hair growth and help stop hair loss in men with androgenetic alopecia (AGA). However, it is not convenient for patients to continue applying the solution twice daily on a regular basis. Tretinoin is known to increase the percutaneous absorption of minoxidil and, therefore, to enhance the response of AGA to minoxidil. For this reason, it was assumed that tretinoin would be helpful in alleviating the inconvenience associated with the recommended twice-daily application of minoxidil.n Objective: To compare the efficacy and safety of therapy using a combined solution of 5% minoxidil and 0.01% tretinoin once daily with those of the conventional 5% topical minoxidil therapy applied twice daily in the treatment of AGA.n Methods: A total of 31 male patients (aged 28–45 years, mean 39.7 ± 4.5) with AGA (Hamilton-Norwood classification type III–V) were randomly assigned into two groups, one in which 5% minoxidil was applied to the scalp twice daily and the other in which the combined agent was applied once daily at night together with a vehicle placebo in the morning. The efficacy parameters were: (i) changes in total hair count, non-vellus hair count, anagen hair ratio, linear hair growth rate, and mean hair diameter assessed by macrophotographic image analysis; and (ii) the patient’s and investigator’s subjective assessments.n Results: After therapy, increases in the macrophotographic variables of total hair count and non-vellus hair count were shown in both treatment groups. There were no statistically significant differences between the two treatment groups with respect to changes in macrophotographic variables or scores on subjective global assessments by patients and the investigator. The incidence of adverse effects such as pruritus or local irritation was similar in the 5% minoxidil group (4 of 14 subjects) and the combined agent group (5 of 15 subjects).n Conclusion: The efficacy and safety of combined 5% minoxidil and 0.01% tretinoin once-daily therapy appear to be equivalent to those of conventional 5% minoxidil twice-daily therapy for the treatment of AGA.

Facial verruca plana that developed after semipermanent tattooing.

Tattooing is becoming more popular around the world. As a result, the reported complications of tattoo are increasing. Local inflammation, infection and allergic reactions are the most common adverse effects. We report here on a healthy 39-year-old woman who developed multiple verruca plana lesions after undergoing semipermanent tattooing. The tattooing had been done 1 year earlier by an amateur.

Eruptive pseudo-angiomatosis lesions are associated with intravascular neutrophils and do not harbour Epstein–Barr virus

Backgroundu2002 Eruptive pseudo‐angiomatosis (EPA) is a rare, relatively newly described cutaneous disorder characterized by the sudden onset of several bright red, angioma‐like papules surrounded by blanched halo. Its aetiology is unknown; however, viral infection or mosquito bites have been speculated as possible causes.
