Long-term follow-up of pediatric trachyonychia.

Pediatric trachyonychia is an acquired nail disease that can cause distress to families. It is a poorly understood disease, and long-term follow-up data are lacking. We present an institutional review of 11 children with isolated pediatric trachyonychia followed over time. Children with the diagnosis of pediatric trachyonychia were identified and invited to participate. Pictures were taken on follow-up and a questionnaire was answered. Exclusion criteria include having another diagnosis at the initial visit that causes nail dystrophy. Eleven patients with the diagnosis of pediatric trachyonychia were available for follow-up. The mean age of appearance was 2.7 years (range 2-7 yrs) and the average follow-up was 66 months (range 10-126 mos). Nine patients were treated with potent topical corticosteroids, one used only petrolatum, and one took vitamin supplements. One patient was found to have an additional skin and hair diagnosis of alopecia areata on follow-up. On follow-up, 82% noted improvement of the nails, whereas 18% noted no change. A majority of cases of pediatric trachyonychia are isolated and improve with time, regardless of treatment.

Acute genital ulcers in nonsexually active young girls: case series, review of the literature, and evaluation and management recommendations.

Acute genital ulcers rarely occur in nonsexually active young girls. When present, they can cause significant physical and emotional distress for the patient and her parents, and prompt an evaluation for sexual abuse and sexually transmitted diseases. With this review, we aim to further characterize acute genital ulcers in nonsexually active young girls by reviewing the medical records of patients with this disorder and to offer an approach to the diagnosis, evaluation, and treatment of acute genital ulcers based on our understanding and knowledge of this condition. We retrospectively review our understanding and knowledge of acute genital ulcers in nonsexually active girls at a pediatric hospital. A review of the recent literature on acute genital ulcers and a multidisciplinary approach to the diagnosis, evaluation, and treatment of acute genital ulcers are also presented. Twelve patients presented with acute genital ulcers, 11 of which were hospitalized for evaluation and pain management. Extensive work-up failed to reveal a specific infectious or autoimmune etiology in all but one patient, who was diagnosed with acute mycoplasma pneumonia. Acute genital ulcers in nonsexually active young girls likely represent a form of idiopathic vulvar aphthosis. Evaluation of a first episode of acute genital ulcers with mild prodromal symptoms should be limited. Treatment consists primarily of supportive care and symptom relief.

Hot tub folliculitis or hot hand-foot syndrome caused by Pseudomonas aeruginosa.

Pseudomonas aeruginosa is a ubiquitous gram-negative rod that can cause a well-recognized, acquired skin infection from bacterial colonization of contaminated water called "hot tub folliculitis." We report an outbreak of pseudomonas skin infection associated with the use of a hot tub at a pool party in 33 children. In particular, 2 of the children were admitted to our hospital; both presented with high leukocyte counts, intermittent low grade fevers, and painful, erythematous nodules and papules on their palms and soles. One of the 2 children also presented with small erythematous pustular lesions on the face and trunk, which led to the diagnosis. Cultures from these pustules grew P aeruginosa. Thirty two other children at this pool/hot tub party developed similar lesions of varying severity 6 to 48 hours after the party. These findings were most consistent with the diagnosis of pseudomonas folliculitis/hot hand.
