RESUMO

La Hidradenitis Supurativa (HS) es una enfermedad inflamatoria crónica de la piel, en la que se han utilizado múltiples tratamientos, con respuesta variable. Se presenta el caso de una paciente con HS sin resistencia a la insulina, que fue tratada satisfactoriamente utilizando metformina oral. Paciente mujer de 22 años, consultó por HS de cuatro años de evolución. Presentaba sobrepeso, pero no resistencia a la insulina ni síndrome de ovario poliquístico. Durante los primeros seis meses de tratamiento recibió antibióticos orales, antibióticos tópicos, cloruro de aluminio tópico y corticosteroides intralesionales, con escasa respuesta. Después de estos tratamientos, se le indicó metformina y luego de doce días de tratamiento todas las lesiones inflamatorias remitieron. Un año después, no ha presentado nuevas lesiones. La metformina podría ser una excelente opción de tratamiento para los pacientes con HS no necesariamente asociada con resistencia a la insulina.


Hidradenitis suppurativa (HS) is a chronic and often devastating inflammatory skin disorder. Many treatments have been used, however none of them is consistently effective. We report the case of a patient with HS without insulin resistance who was successfully treated using oral metformin. A 22 years old woman consulted at our dermatology department with a four years history of HS. There was no insulin resistance or polycystic ovary syndrome. However, the patient was overweight. During the first six months of treatment the patient received oral antibiotics, topical antibiotics, oral zinc, topical aluminum chloride and intralesional corticosteroids with a poor response. After all these treatments, the patient was started metformin on a daily basis. After twelve days of treatment all inflammatory lesions resolved. One year later, no new lesions have appeared. Metformin might be an excellent treatment option for patients with HS not necessarily associated with altered glucose metabolism.

RESUMO

Nowadays, Diabetic Neuropathy (DN) is considered the most common cause of peripheral neuropathy in clinical practice. It can affect sensitive, motor or autonomic nerve fibers, with symmetric, asymmetric, acute or chronic presentations. Due to this variability, with multiple physiopathologic mechanisms involved, a complex clinical classification has been used until recently. The aim of this review is to present a new classification of diabetic neuropathy, based on its physiopathology. It is divided in metabolic microvascular and hypoxic, autoimmune and inflammatory, compressive, secondary to complications ofdiabetes and related to treatment. It must be understood that DN is notjust a functional disease, but a complication of diabetes with molecular and pathological substrates caused by hyperglycemia. Therefore, normalization of blood glucose is a fundamental step towards the successful prevention and treatment of DN.

RESUMO

El síndrome de Gianotti-Crosti, también llamado acrodermatitis papular de la infancia, es un exantema infrecuente de la infancia, que se presenta generalmente en niños entre 1 y 6 años de edad. Dado que estos pacientes generalmente son llevados a su pediatra, es fundamental el conocimiento de las características de este síndrome. El cuadro clínico se caracteriza por una reacción pápulo-vesicular asintomática y autolimitada de distribución simétrica en cara, nalgas y superficies extensoras de las extremidades, formando placas o permaneciendo aisladas. El tronco generalmente se encuentra respetado y las lesiones usualmente no son pruriginosas. Se reportan los casos de dos pacientes que consultaron en el Servicio de Dermatología de la Pontificia Universidad Católica de Chile, por un cuadro compatible con síndrome de Gianotti-Crosti. A propósito de los casos, se presentan los aspectos más relevantes sobre esta patología.


The Gianotti-Crosti syndrome, also known as papular acrodermatitis of childhood, is an uncommon rash that usually occurs in children between 1 and 6 years old. Given that these patients are usually brought to their pediatrician, it is essential to know the characteristics of this syndrome. The clinical picture is characterized by a self-limited and asymptomatic papulo-vesicular reaction, symmetrically distributed on the face, buttocks and extensor surfaces of the extremities. The trunk is generally respected and the lesions are usually not itchy. We report the cases of two patients treated at the Dermatology Department at the Pontificia Universidad Católica de Chile, with symptoms consistent with Gianotti-Crosti syndrome. We also present the most relevant aspects of this disease.

RESUMO

Las disrafias espinales ocultas son patologías caracterizadas por la fusión incompleta del tubo neural, en las que la lesión se encuentra cubierta por piel y no hay exposición del tejido nervioso. El diagnóstico precoz es de gran importancia, ya que la corrección quirúrgica oportuna puede prevenir daño neurológico irreversible. Existen alteraciones cutáneas que se asocian a la presencia de disrafias espinales ocultas. Debido a que en muchos casos estos marcadores cutáneos son la única manifestación inicial de estas alteraciones, es fundamental que el pediatra esté familiarizado con ellos, para poder realizar un estudio diagnóstico y terapéutico adecuado. Dentro de los marcadores cutáneos descritos en la literatura, una combinación de dos o más alteraciones cutáneas congénitas de la línea media constituye probablemente el predictor más importante de disrafia espinal oculta. Lesiones como el lipoma de la línea media y la cola de fauno son los marcadores aislados de mayor riesgo. Actualmente las disrafias espinales ocultas cuentan con cobertura GES, por lo que todo paciente en el que se sospeche el diagnóstico, debe ser derivado a neurocirujano, quien deberá evaluarlo en un plazo máximo de tres meses.


Occult spinal dysraphism are diseases characterized by the incomplete fusion of the neural tube, where the lesion is covered by skin and there is no exposure of nerve tissue. Early diagnosis is very important, because prompt surgical correction can prevent irreversible neurological damage. There are usually skin changes associated with the presence of occult spinal dysraphism. Because in many cases these skin lesions are the only initial manifestation of the disease, it’s essential for the pediatrician to know them well, for achieving a timely and appropriate diagnosis. Among the skin markers described in the literature, a combination of two or more skin lesions of the midline is probably the best predictor of occult spinal dysraphism. Lesions such as lipoma of the midline and faun tail have the highest risk for these disorders. Occult spinal dysraphism have GES financing, so every patient in whom the diagnosis is suspected should be referred to a neurosurgeon, who will perform an evaluation within three months.

RESUMO

La amiloidosis conjuntival es una condición infrecuente en la práctica clínica, que se caracteriza por el depósito de material amiloide de la conjuntiva. Se estima que es la causa del 0,002 por ciento de las lesiones conjuntivales. Dada la baja incidencia de esta patología, existen pocos reportes en la literatura. En este trabajo se presentan los casos clínicos de tres pacientes con amiloidosis conjuntival que fueron atendidos en nuestro centro y se propone una aproximación diagnóstica para evaluar la existencia de amiloidosis sistémica.


Conjunctival amyloidosis is a rare condition characterized by the localized deposition of amyloid material in the conjunctiva. It's supossed to be the cause of 0.002 percent of conjunctival lesions. Given the low incidence of this disease, there are few reports in the literature. In this manuscript we present the cases of three patients with primary conjunctival amyloidosis who were attended at our institution. We also propose a diagnostic algorithm to rule out systemic amyloidosis in patients in whom the finding is conjunctival amyloidosis.
