Clinical evaluation of infantile hemangiomas treated with atenolol.

Currently, propranolol, is the first line treatment for problematic infantile hemangioma (IH) management. However, serious side effects have been reported. For that reason, atenolol, a hydrophilic selective beta-1 blocker with the potential for fewer side effects, has been explored. A descriptive, observational case series study of 30 patients between the ages one to 5 months with superficial, deep, or mixed IH was conducted between January 2016 and December 2017. Oral atenolol was administered using a single once daily dose of 1mg/kg, which was adjusted for weight gain each month. The IH was assessed using the Hemangioma Activity Score (HAS) at initiation of treatment, four months, and 9 months of age and improvement percentage was calculated at four and nine months of age. A total of 25 patients completed three evaluations. The baseline, four-month, and 9-month HAS were 4.6, 2.39, and 0.65, respectively. Mean improvement percentage at four months of age was 46.76% and at 9 months of age was 85.65%. No side effects were reported. This study suggests atenolol as an effective treatment for IH in almost all cases, especially in patients who initiated treatment before three months of age. It was well tolerated in all our cases.

We present a case of neonatal leukemia cutis highlighting its dermoscopic features, the presence of fine telangiectatic arborizing vessels distributed within a pink background within all lesions.

A randomized, controlled trial of oral propranolol in infantile hemangioma.

BACKGROUND: Oral propranolol has been used to treat complicated infantile hemangiomas, although data from randomized, controlled trials to inform its use are limited. METHODS: We performed a multicenter, randomized, double-blind, adaptive, phase 2-3 trial assessing the efficacy and safety of a pediatric-specific oral propranolol solution in infants 1 to 5 months of age with proliferating infantile hemangioma requiring systemic therapy. Infants were randomly assigned to receive placebo or one of four propranolol regimens (1 or 3 mg of propranolol base per kilogram of body weight per day for 3 or 6 months). A preplanned interim analysis was conducted to identify the regimen to study for the final efficacy analysis. The primary end point was success (complete or nearly complete resolution of the target hemangioma) or failure of trial treatment at week 24, as assessed by independent, centralized, blinded evaluations of standardized photographs. RESULTS: Of 460 infants who underwent randomization, 456 received treatment. On the basis of an interim analysis of the first 188 patients who completed 24 weeks of trial treatment, the regimen of 3 mg of propranolol per kilogram per day for 6 months was selected for the final efficacy analysis. The frequency of successful treatment was higher with this regimen than with placebo (60% vs. 4%, P<0.001). A total of 88% of patients who received the selected propranolol regimen showed improvement by week 5, versus 5% of patients who received placebo. A total of 10% of patients in whom treatment with propranolol was successful required systemic retreatment during follow-up. Known adverse events associated with propranolol (hypoglycemia, hypotension, bradycardia, and bronchospasm) occurred infrequently, with no significant difference in frequency between the placebo group and the groups receiving propranolol. CONCLUSIONS: This trial showed that propranolol was effective at a dose of 3 mg per kilogram per day for 6 months in the treatment of infantile hemangioma.

Vegetating Candidiasis: A Mimicker of Squamous Cell Carcinoma in Keratitis Ichthyosis Deafness Syndrome.

Keratitis ichthyosis deafness (KID) syndrome is a rare genodermatosis with a high risk of cutaneous malignancy and infections. Infections can induce pseudocarcinomatous epidermal hyperplasia, leading to erroneous diagnosis of squamous cell carcinoma. We present a pediatric case of KID syndrome with vegetating plantar and acral candidiasis and highlight the importance of correct biopsy technique and clinicopathologic correlation in appropriate management.

Congenital Degos Disease: Case Report and Dermoscopic Findings.

Pediatric Degos disease is rare, with only 36 cases reported in the medical literature. Classically the diagnosis has been established according to pathognomonic histopathologic findings, but when these features are not present, there may be a delay in diagnosis. We report the second congenital case of Degos disease, highlighting the clinical and dermoscopic findings.

Norwegian scabies in Peru: the impact of human T cell lymphotropic virus type I infection.

Isolates cases and groups of patients co-infected with human T cell lymphotropic virus type I (HTLV-I) and Norwegian scabies have been previously reported. Peru is considered to be endemic for HTLV-I. Between June 1999 and December 2000, 23 patients with Norwegian scabies were enrolled in this study after written informed consent was obtained. Antibodies against HTLV-I were detected by an enzyme-linked immunosorbent assay and confirmatory Western blot. Patients ranged in age from 3 months to 84 years; 15 (65.2%) were female. Infection with HTLV-I was found in 16 (69.6%) patients. Comorbid features included corticosteroid therapy (8.6%), malnutrition (8.6%), and Down's syndrome (4.3%). Among those who consented to be tested for human immunodeficiency virus (n = 13, 56.5%), no one had a positive result. The three patients that reported one or more prior episodes of Norwegian scabies were infected with HTLV-I and two of these HTLV-I-positive patients died. Infection with HTLV-I is an important co-factor related to Norwegian scabies in Peru. In our setting, the evaluation for HTLV-I in all Norwegian scabies cases is highly recommended, especially when no other risk factors are apparent.

El síndrome de Sweet, también llamado dermatosis neutrofílica febril aguda es una enfermedad sistémica de etiología desconocida, poco frecuente en la población general y raramente diagnosticada en la infancia. Se caracterizada por presentar pápulas y/o nódulos eritematovioláceos que coalescen formando placas dolorosas, fiebre y leucocitosis con neutrofilia, y la presencia de un denso infiltrado dérmico neutrofílico en la histopatología cutánea. Presentamos el caso inusual de un adolescente de 13 años de edad que presentó una variante ampollar del síndrome de Sweet.

Sweet’s syndrome or acute febrile neutrophilic dermatosis is a systemic disease of unknown aetiology, very infrequent in general population and rarely diagnosed in childhood. It is characterized by the presence of papules and/or nodules that coalesce to form painful erythematous and violaceous plaques, fever, neutrophilic leucocytosis and a massive neutrophilic dermal infiltrate on skin histopathology. We present the unusual case of a 13 years old adolescent who presented a bullous variant of Sweet syndrome.

Presentación inusual de morfea en placas en un niño / Unusual presentation of morphea in plates in child

La morfea de presentación infantil se caracteriza por manifestarse como lesiones lineares, localizadas con mayor frecuencia en uno de los miembros o en la región facial. La morfea tiene mayor prevalencia en el sexo femenino. Se presenta el caso de un niño de once años sin morbilidad adicional, con lesiones planas, hiperpigmentadas y atróficas, localizadas en la parte medialy lateral del tercio inferior de ambas piernas. Las lesiones fueron confirmadas histopatologicamente como morfea superficial.

Child onset morphea is usually characterized by linear lesions, more frequently located in one limb or in the facial region, more prevalent in white female children. We report the case of a 11year-old male child without additional morbidity, with atrophic and hyperpigmented flat plaque lesions, located in the inner and outer side of the lower third part of both legs. The lesions were pathologically confirmed as superficial morphea.

Eruptive pseudoangiomatosis.

We describe two children with acute onset and spontaneous resolution of angioma-like papules during a viral illness. The biopsy specimens from both patients showed a unique histologic appearance consisting of dilated dermal blood vessels with plump, hobnail-shaped endothelial cells. On the basis of the natural history and the histopathologic features we suggest the diagnosis of eruptive pseudoangiomatosis.

Beta-bloqueadores y hemangiomas: de lo fortuito a lo accidental / Beta-blockers and hemangiomas, as incidental to the accidental

Los hemangiomas infantiles son tumores vasculares benignos y los más comunes en la infancia. Se localizan, en un 80% de los casos, en cabeza y cuello. Complicaciones serias ocurren en el 20% de ellos. Los corticoides orales han sido el tratamiento de primera línea para los hemangiomas agresivos y complicados, pero con una respuesta satisfactoria en el 75% de casos, asociada a una carga alta de efectos adversos. Los beta-bloqueadores orales, como el propranolol, son la alternativa actual para estos casos. Ésta droga es actualmente considerada de primera línea dado que ofrece una alta y rápida efectividad sin efectos adversos de riesgo. El timolol tópico se convierte en la mejor alternativa para el tratamiento de los hemangiomas pequeños y localizados.

Infantile hemangiomas are common and benign vascular tumors. In 80% of cases they are located on the head and neck. Serious complications occur in 20% of them. Oral corticosteroids have been the first line treatment in aggressive and complicated hemangiomas, but satisfactory response occurs in 75% of cases associated with a high burden of adverse effects. Oral beta-blockers such as propranolol are the current alternative for these cases. Propranolol is now considered as a first line treatment because it offers high and fast efficiency without serious adverse effects. Topical timolol becomes the best alternative for the treatment of small and localized hemangiomas.

Dermatitis infectiva: una revisión: a propósito de una experiencia peruana / Infective dermatitis: a review: about Peruvian experience

La dermatitis infectiva es una enfermedad eccematosa crónica de la niñez, que siempre compromete el cuero cabelludo y puede progresar a leucemia/linfoma de células T o a paraparesia espástica tropical. Es una condición dermatológica especial que está relacionada a la infección por el retrovirus linfotrópico humano a células T de tipo 1 (HTVL-1). En la niñez la forma de trasmisión más importante es a través de la lactancia materna. La expresión clínica así como su progresión están relacionadas con la carga viral, condiciones inmunológicas del paciente (infestación por Strongiloides stercoralis) y la intensidad de la respuesta inflamatoria. En esta revisión se destacan las características clínicas de esta entidad y se resaltan además sus hallazgos histopatológicos.

Infective dermatitis is a chronic, eczematous dermatitis of childhood that always involves the scalp and may progress to adult T-cell leukemia/lymphoma or tropical spastic paraparesis. It is a special dermatologic condition that has been linked to human T-cell lymphotropic virus type 1 (HTLV-1) infection. The most important route of transmission is vertical through breast-feeding. The clinical expression as well as its progression is related to viral load, immune status of patients (infestation by Strongyloides stercoralis) and the intensity of the inflammatory response. This review highlights the clinical features of this entity and also emphasizes its histopathological findings.

Escrofuloderma asociada a osteítis tuberculosa / Scrofuloderma associated with tuberculous osteitis

La escrofuloderma es una forma de tuberculosis cutánea que resulta de la extensión directa a la piel de un foco tuberculoso contiguo (linfático u óseo), con frecuente fistulización y evolución crónica, pudiendo ocurrir curación espontánea que deja cicatriz retráctil. Se presenta el caso de un paciente varón de 7 años de edad, que presenta dos úlceras en la pared torácica izquierda con un aumento del volumen torácico del mismo lado de 7 meses de evolución; recibe tratamientos antibióticos múltiples y curaciones sin mejoría. En la radiografía de tórax se evidencia compromiso de pleura y arcos costales izquierdos, que es compatible con osteítis tuberculosa. Se realiza biopsia de piel, observándose granulomas tuberculoides con necrosis caseosa y coloración Ziehl Neelsen positiva para BAAR. Inicia tratamiento con tuberculostáticos obteniendo una mejoría clínica evidente. A las 8 semanas de iniciado el tratamiento, se obtiene cultivo positivo para Mycobacterium tuberculosis.

The scrofuloderma is a form of cutaneous tuberculosis that results of the extension of a contiguous tuberculous focus (lymphatic or bone) to the skin, with frequent fistulization and chronic evolution; spontaneous healing may occur in some cases leaving a scar. We present the case of a 7 years old male patient who complained of two ulcers with deformation of the thoracic wall that started 7 months previous to the diagnosis. He received multiple antibiotic treatments without improvement. The chest radiograph showed left pleura and costal arches involvement. Skin biopsy showed the presence of tuberculoid granulomas with caseous necrosis, and Ziehl Neelsen staining was positive for BAAR. The patient received tuberculostatic treatment and had clinical improvement. After 8 weeks of treatment, the culture resulted positive for Mycobacterium tuberculosis.

El granuloma tricofítico de Majocchi es una infección causada por hongos dermatofitos que invaden dermis profunda y tejido celular subcutáneo. Existen pocos reportes de esta entidad. Se han descripto diferentes características clínicas de acuerdo al estado inmune del paciente. Presentamos el caso de una paciente de 8 años de edad con múltiples nódulos ligeramente dolorosos, en cuero cabelludo y cara, de 6 meses de evolución, que había sido tratada con corticoides tópicos y sistémicos. El estudio anatomopatológico evidenció abundantes estructuras micóticas con formación de granulomas en dermis profunda. Se estableció el diagnóstico de granuloma tricofítico de Majocchi y se inició terapia antimicótica con itraconazol, 5 mg/kg/día, con mejoría clínica parcial a la cuarta semana de tratamiento

Trichophytic Majocchi granuloma is an infection by dermatophytes which invade deep dermis and fat. There are few reports about this disease. Some clinical features have been described depending on immune state of patients. We present a case in an 8 years old girl with tenderness nodules in scalp and face of 6 months of evolution, who had been previously treated with topical and systemic steroids. Histological findings showed many fungal structures and a dermal granulomatous inflammatory infiltrate in deep dermis. Diagnosis of trichophytic Majocchi granuloma was done and initiated anti fungal therapy with itraconazole 5 mg/kg once a day with partial improvement at the fourth week of treatment
