ABSTRACT
Abstract Spitz nevus is a benign melanocytic lesion, which presents in several ways: solitary, agminated, or disseminated. The disseminated variant is uncommon; it may have a rapid evolution (the eruptive form) and be difficult to manage. This report presents the case of a 24-year-old patient with multiple papules on his limbs, which had appeared four years previously. On physical examination, 120 pink and skin-colored papules were seen, which under dermoscopy were observed to be homogeneous, pink vascular lesions. Histopathologic study revealed epithelioid cells arranged in groups or singly in the dermis and dermo-epidermal junction. They were HMB-45 positive in the superficial dermis, and Ki-67 < 1%. Given these findings, a diagnosis of eruptive disseminated Spitz nevi was made.

El síndrome de Sweet es una dermatosis inflamatoria poco común, que se ha asociado a tumores malignos, principalmente de tipo hematológico. Presentamos un caso clínico de síndrome de Sweet asociado con una rara neoplasia pancreática, siendo uno de los pocos casos reportados en la literatura médica acerca de esta asociación.
Sweet's syndrome is an uncommon inflammatory dermatosis, which has been associated with malignant tumors, mainly of hematological type. We report a clinical case of Sweet syndrome associated with a rare pancreatic neoplasm, which is one of the few cases reported in the medical literature about this association.

La parotiditis crónica recurrente infantil (PCRI) es una patología relevante. Su diagnóstico es principalmente clínico, pero se apoya en exámenes imagenológicos. El enfoque actual del tratamiento es diverso. El objetivo es realizar una revisión actualizada sobre las características clínicas, exámenes complementarios, modelos etiopatogénicos y protocolos terapéuticos. MATERIAL Y MÉTODO: Se realizó una búsqueda bibliográfica en PUBMED utilizando los términos libres y términos MESH: PCRI, parotiditis recurrente, parotiditis crónica y parotiditis. Los filtros utilizados fueron pacientes humanos, hasta 18 años, con resumen. En el buscador Scielo se incluyeron los términos libes Parotiditis y crónica. Se incluyeron artículos publicados en idiomas inglés, español o portugués hasta el año 2017. RESULTADOS: En el buscador PUBMED se encontraron 119 artículos de los cuales sólo se incluyeron 44. La exclusión de los artículos restantes se debió a idioma, acceso al artículo o ausencia de relación entre el artículo y la revisión propuesta. En el buscador Scielo se encontraron 6 artículos de los cuales 5 fueron seleccionados. La evaluación multidisciplinaria permite el tratamiento oportuno. Su diagnóstico es clínico pero se apoya en exámenes imagenológicos, como la ecografía y la sialografía. CONCLUSIONES: El enfoque actual de tratamiento es conservador, y la mejor evidencia disponible apoya el uso de sialendoscopia con irrigación y administración de antibióticos y/o corticoides vía conducto parotídeo, sin embargo, existirían buenos resultados con lavados intraglandulares con soluciones fisiológicas sin necesidad de sialendoscopio.
Recurrent childhood chronic parotiditis (RCCP) is a relevant pathology. Its diagnosis is mainly clinical, but it relies on imaging tests. The current treatment approach is diverse. The aim of this article is to update the clinical features, complementary tests, etiopathogenic models and therapeutic protocols of this disease. MATERIAL AND METHOD: A bibliographic search was performed in PUBMED using the free terms and MESH terms: RCCP, recurrent parotiditis, chronic parotiditis and parotiditis. The filters used were human patients, up to 18 years old, with abstract. In SCIELO the free terms included were Parotiditis and chronic. Articles published in English, Spanish or Portuguese until 2017 were included. RESULTS: In PUBMED 119 articles were found and 44 were included. The exclusion of the remaining articles was due to language, access to the article or absence of relationship between the article and the proposed revision. In SCIELO 6 articles were found 6 of which 5 were selected. The multidisciplinary asses of patients with RCCP is considered the appropriate treatment. Its diagnosis is clinical but it relies on imaging tests, such as echography and sialography. CONCLUSIONS: The current treatment approach is conservative, and the best available evidence supports the use of sialendoscopy with irrigation and administration of antibiotics and/or corticosteroids via the parotid duct. However, there would be proper results with intraglandular lavage with physiological solutions without the need for a sialendoscope.

Congenital hearing loss is the total or partial inability to hear sounds through the ears. It is the most common disability in newborns in Chile and worldwide, and is a permanent condition. The direct impact on children who are not adequately diagnosed is the alteration in acquisition of language and cognitive skills and a decline in their social and school insertion, jeopardizing their professional and potentially productive life. Universal screening programs for hearing loss are essential for the diagnosis, since 50% of infants with hearing loss have no known risk factor. Screening before one month of age, confirmation before 3 months, and effective intervention before 6 months, allows the development of these children as if they had normal hearing. In Chile there is a selective program of screening for infants aged less than 32 weeks or 1,500 grams, as part of Explicit Health Guarantees, but it covers only 0.9% of newborns per year. Therefore, a large majority of children remain without diagnosis. The aim of this review is to compare the situation in Chile with other countries, raising the need to move towards a universal neonatal hearing loss screening program, and propose necessary conditions in terms of justification and implementation of a universal screening public policy.
