Skin manifestations of obesity: a comparative study

Background  Obesity is one of the world’s biggest health problems nowadays. Little research has been done on the skin diseases that affect obese patients.

Skin symptoms as diagnostic clue for autoinflammatory diseases

Autoinflammatory disorders are immune-mediated diseases with increased production of inflammatory cytokines and absence of detectable autoantibodies. They course with recurrent episodes of systemic inflammation and fever is the most common symptom. Cutaneous manifestations are prevalent and important to diagnosis and early treatment of the syndromes. The purpose of this review is to emphasize to dermatologists the skin symptoms present in these syndromes in order to provide their early diagnosis.

Prevalence and characterization of neonatal skin disorders in the first 72 h of life

OBJECTIVE To determine the prevalence of neonatal dermatological findings and analyze whether there is an association between these findings and neonatal and pregnancy characteristics and seasonality. METHODS Newborns from three maternity hospitals in a Brazilian capital city were randomly selected to undergo dermatological assessment by dermatologists. RESULTS 2938 neonates aged up to three days of life were randomly selected, of whom 309 were excluded due to Intensive Care Unit admission. Of the 2530 assessed neonates, 49.6% were Caucasians, 50.5% were males, 57.6% were born by vaginal delivery, and 92.5% of the mothers received prenatal care. Some dermatological finding was observed in 95.8% of neonates; of these, 88.6% had transient neonatal skin conditions, 42.6% had congenital birthmarks, 26.8% had some benign neonatal pustulosis, 2% had lesions secondary to trauma (including scratches), 0.5% had skin malformations, and 0.1% had an infectious disease. The most prevalent dermatological findings were: lanugo, which was observed in 38.9% of the newborns, sebaceous hyperplasia (35%), dermal melanocytosis (24.61%), skin desquamation (23.3%), erythema toxicum neonatorum (23%), salmon patch (20.4%), skin erythema (19%), genital hyperpigmentation (18.4%), eyelid edema (17.4%), milia (17.3%), genital hypertrophy (12%), and skin xerosis (10.9%). CONCLUSIONS Dermatological findings are frequent during the first days of life and some of them characterize the newborns skin. Mixed-race newborns and those whose mothers had some gestational risk factor had more dermatological findings. The gestational age, newborns ethnicity, gender, Apgar at the first and fifth minutes of life, type of delivery, and seasonality influenced the presence of specific neonatal dermatological findings.

Vohwinkel syndrome: ichthyosiform variant in a family

Vohwinkel syndrome belongs to the group of hereditary palmoplantar keratoderma, having an autosomal dominant inheritance. In this report, the authors present a case of a four-year-old boy with diffuse scaling over his entire body and transgredient palmoplantar hyperkeratosis with some fissured areas. Family evaluation revealed that his mother and other family members were affected. Based on his clinical findings and on family history, the diagnosis of the ichthyotic Vohwinkel syndrome subtype, characterized by generalized ichthyosis and palmoplantar hyperkeratosis, was established.Vohwinkel syndrome belongs to the group of hereditary palmoplantar keratoderma, having an autosomal dominant inheritance.

Epidemiology and Predisposing Factors for Erythema Toxicum Neonatorum and Transient Neonatal Pustular: A Multicenter Study

Erythema toxicum neonatorum (ETN) and transient neonatal pustular melanosis (TNPM) are benign pustular skin conditions that are relatively common in newborns, but the predisposing factors for these conditions are unknown. Our goal was to verify the prevalence of ETN and TNPM and their predisposing factors in a large sample of neonates.

Nail psoriasis treated with pulsed dye laser

Nail changes are present in about 50% of psoriasis patients and tend to be refractory to conventional treatments. Pulsed dye laser has emerged as an alternative therapy. Our aim is to evaluate the efficacy of pulsed dye laser in nail psoriasis and the impact of treatment on quality of life. Fourteen patients were treated in monthly sessions for three months. The outcome assesment was made by the Nail Psoriasis Severity Index (NAPSI). The median improvement in the scores of the overall NAPSI, nail bed NAPSI, and nail matrix NAPSI were 44.2% (P = 0.002), 50% (P = 0.033) and 65.1% (P = 0.024), respectively.

Syndrome in question. A case of Cowden´s syndrome.

The authors describe a case of Cowden´s syndrome in a female patient with classic cutaneous lesions, plus papillomatous lesions in the gastrointestinal tract and a previous history of thyroid carcinoma. Mucocutaneous lesions occur in 90% of Cowdens syndrome cases and are characterized by facial trichilemmomas, oral mucosal papillomas and benign acral keratoses. Sites of extracutaneous involvement include: the thyroid, gastrointestinal tract, breast and endometrial tissue. There is risk of malignancies in these organs and they need to be monitored with imaging tests. The early diagnosis of the syndrome by a dermatologist through mucocutaneous lesions enables the investigation and diagnosis of extracutaneous involvement.
