Plantar keratoderma-like crusted scabies in an immunocompetent infant after topical steroids.

A healthy 6-month-old girl presented with plantar keratoderma-like lesions unresponsive to topical corticosteroids. Nocturnal pruritus in 13 relatives, presence of burrows on clinical exam, and the positive scabies preparation led to the diagnosis of crusted scabies. She was successfully treated with topical and oral scabicides. Crusted scabies is a severe form of Sarcoptes scabiei infection uncommon in immunocompetent subjects, in whom previous corticosteroid use may favor its occurrence.

New Skin Flaps for Triangular Surgical Defects: Design, Assessment on Experimental Model, and Clinical Outcomes.

BACKGROUND: Most skin flaps are designed to repair circular surgical defects after skin tumor excisions, but few flaps have been described to reconstruct triangular defects. OBJECTIVE: The aim of this study was to describe new skin flaps for triangular surgical defects using an innovative experimental model. METHODS: We tested new flap designs in an experimental pig skin model using a tension sensor to measure maximum tension and tension augmentation when the flap is performed in an area of increased basal tension. The results were compared with those from classic flaps. Finally, the new flaps were performed on a series of patients with triangular surgical defects. RESULTS: Six new flaps with adequate levels of tension were obtained and named after their morphology: spider crab, mantis, toy windmill, nautilus, origami bird, and clover. These new flaps were successfully performed on a series of 40 patients; among them, spider crab and mantis flaps showed a better response to basal tension augmentation. CONCLUSIONS: Six new flaps for triangular surgical defects were proposed and successfully performed in a series of 40 patients, using an experimental pig skin model and a tensiometer.

Caliber-persistent labial artery: report of 3 cases.

The caliber-persistent labial artery is a vascular anomaly in which a primary arterial branch penetrates into the submucosal tissue without reduction in diameter. Most lesions are benign and do not require treatment, except for complications and/or on patient demands. In this way, noninvasive diagnostic tools are preferred such as high-resolution and color Doppler ultrasonography which allow direct observation of the lesion, assessing its exact location and diameter at every axis, as well as the blood flow velocity. An excisional biopsy of these lesions or even their surgical extirpation could have a fatal outcome with profuse bleeding.

Una biopsia corial que da en el clavo: síndrome de Nicolau en gestante / A chorionic biopsy with fortuitous results: Nícolau syndrome in pregnant women

Presentamos a una gestante de 40 años, en la semana 12+6. Al obtener riesgo alto en el cribado del primer trimestre, se procedió a la biopsia corial por vía abdominal. Cuando se introdujo el anestésico local, la paciente comenzó con un dolor punzante sobre la zona de inyección, cambiando inmediatamente de color a rojo vinoso. Tras consultar con dermatología, se diagnosticó de síndrome de Nicolau, un vasoespasmo agudo por la inyección intraarterial de anestésico, que lleva a necrosis del tegumento cutáneo subsidiario a este. Dada la escasa prevalencia de esta afección, consideramos necesario elaborar una revisión bibliográfica sobre este síndrome

We present a 40-year-old pregnant woman, at week 12 + 6. By getting high risk in the first three months period screening, we abdominally proceeded to chorionic villus sampling. When the local anesthetic was introduced, the patient began with a shooting pain on the injection site, changing into a wine-red colour. After consultating with dermatology, she was diagnosed with Nicolau syndrome, an acute vasospasm by intra-arterial injection of anesthetic, leading to necrosis of the skin integument that depends on this. Given the low prevalence of this condition, we consider necessary to develop a literature review on this syndrome

Tinea capitis in adults in southern Spain. A 17-year epidemiological study / Tinea capitis en pacientes adultos del sur de España. Un estudio epidemiológico de 17 años

Background. Tinea capitis is an infection of the hair due to keratinophilic fungi, known as dermatophytes. Although the disease is common in children, several studies have also shown that it is far from unusual in adults, especially in post-menopausal women and immunocompromised persons. Aims. To determine the incidence of tinea capitis in adults in our area, as well as the predisposing factors (gender, immunity), and causative species. Materials and methods. A retrospective study was conducted over a period of 17 years, from 1995 to 2011, collecting data on cases of tinea capitis diagnosed in our dermatology department. Information collected for all patients included age, gender, location of the lesions, results of direct examination and culture, immune status, cause of immunosuppression, and the prescribed treatment. Results. Thirty-three cases (11.4%) out of 289 cases of tinea capitis occurred in adults. Most of these adults (72%) were immunocompetent, and the rest were immunocompromised for different reasons. Three of the patients were men and 30 women, with 70% of the latter being post-menopausal. Trichophyton species were isolated in 76% of these adult patients, with Trichophyton violaceum being the most common. Treatment with oral terbinafine was successful in all these cases. Microsporum species were responsible for the other cases, all treated successfully with oral griseofulvin. Conclusions. This series of tinea capitis in adults is one of the largest to date. It shows that tinea capitis is not uncommon among the immunocompetent adult population. In our geographical area, except for prepubescent patients, most cases affecting the adult population were caused by species of the genus Trichophyton. In these cases the treatment of choice was oral terbinafine, which considerably shortened the treatment time, and was associated with fewer side effects than the classical griseofulvin (AU)

Antecedentes. Tinea capitis es una infección del pelo producida por hongos queratinofílicos llamados dermatofitos. Aunque la enfermedad es más común en niños, varios estudios han demostrado que no es infrecuente en adultos, especialmente en mujeres posmenopáusicas y personas inmunodeprimidas. Objetivo. Determinar la incidencia de tinea capitis en adultos de nuestra área, así como los factores predisponentes (inmunidad, género) y agentes causales. Métodos. Llevamos a cabo un estudio retrospectivo de un periodo de 17 años, desde 1995 a 2012, seleccionando casos de tinea capitis diagnosticados en nuestro departamento de Dermatología. Se recogió información clínico-demográfica de los pacientes que incluyó edad, sexo, localización de las lesiones, resultados de examen directo y cultivos, inmunidad, causa de la inmunosupresión y tratamiento. Resultados. De los 289 casos de tinea capitis, 33 (11,4%) eran de pacientes adultos. La mayoría (72%) fueron inmunocompetentes; la inmunodepresión en el resto de los casos era por diferentes causas. Tres de los pacientes eran hombres y 30 mujeres, la mayoría de las cuales eran posmenopáusicas (70%). Las especies de Trichophyton fueron aisladas en el 76% de los casos, con Trichophyton violaceum como el dermatofito más común; el tratamiento con terbinafina oral fue exitoso en todos los casos. Las especies microspóricas fueron responsables de los casos restantes y tuvieron una buena evolución con griseofulvina. Conclusiones. Esta serie de tinea capitis del adulto es una de las más largas hasta la fecha. Se demuestra que tinea capitis no es infrecuente entre la población adulta inmunocompetente. En nuestra área geográfica, salvo en prepúberes, la mayoría de los casos de tinea capitis de adultos son debidos a especies del género Trichophyton. En estos casos el tratamiento de elección fue la terbinafina oral, que acorta considerablemente la duración de tratamiento y se asocia a menos efectos secundarios que la clásica griseofulvina (AU)

Transient neonatal zinc deficiency due to a new autosomal dominant mutation in gene SLC30A2 (ZnT-2).

Transient neonatal zinc deficiency (TNZD) has a clinical presentation similar to that of acrodermatitis enteropathica but is caused by a low zinc concentration in maternal breast milk. TNZD becomes clinically evident during breastfeeding and is resolved by weaning and the introduction of complementary nutrition. We present a 4-month-old girl with TNZD due to a new autosomal dominant mutation (663delC) in the maternal SLC30A2 gene not previously described in the literature.

Eficacia terapéutica del voriconazol en candidiasis vulvovaginal crónica por Candida glabrata / Efficacy of voriconazole treatment in chronic vulvovaginal candidosis due to Candida glabrata

Antecedentes. La vulvovaginitis candidiásica es una infección frecuente en mujeres jóvenes que se acompaña de alta morbilidad y elevados gastos sanitarios. Objetivos. Las candidiasis vaginales causadas por Candida glabrata constituyen un reto terapéutico dada la resistencia adquirida por muchas cepas de esta especie a los antifúngicos azólicos. Métodos. En este trabajo presentamos 2 casos de candidiasis vaginal complicada por Candida glabrata resistentes a fluconazol y tratadas con voriconazol. Resultados. Las 2 pacientes mejoraron tras la administración de voriconazol, 400mg/12h el primer día y posteriormente 200mg/12h durante 14 días, con desaparición de la sintomatología y la negativización de los cultivos. Conclusiones. En conclusión, los resultados obtenidos nos llevan a sugerir el uso del voriconazol como alternativa terapéutica en este tipo de candidiasis que, aunque no comprometen la vida, llevan asociada una elevada morbilidad(AU)
