RESUMEN
High-grade anal intraepithelial squamous lesion is significantly prevalent among men who have sex with men and are infected with the human immunodeficiency virus. This condition-the precursor to anal cancer-significantly increases the risk of developing it. Conversely, low-grade anal intraepithelial squamous typically follow a benign course and usually regress spontaneously. MATERIALS AND METHODS: To describe a population of men who have sex with men living with human immunodeficiency virus followed in a specialized anal cancer screening unit we conducted an observational, retrospective, and single-center study was. RESULTS: Ninety-four patients were analyzed, with a mean age of 39 ± 9 years, and a 87% positivity rate for high-risk human papillomavirus (HR-HPV). At the initial visit, 47% presented with low-grade squamous intraepithelial lesions. The progression rate to high-grade squamous intraepithelial lesion was 37.2 per 100,000 patients/year. None of the patients developed anal cancer. Tobacco and alcohol consumption were associated with this progression. DISCUSSION: In this series, longer duration of HIV infection, tobacco and alcohol use and the presence of HR-HPV were significantly associated with the occurrence of high-grade intraepithelial lesions. A lower risk of progression was seen in patients with higher education. CONCLUSION: In men who have sex with men living with HIV, the association of factors such as smoking, alcohol, the presence of HR-HPV and an increased burden of human papillomavirus disease makes these patients more susceptible to develop high-grade anal squamous lesions.
RESUMEN
Describimos el caso de una paciente con vainas peripilares por utilizar peinados a tensión tipo cola de caballo. El problema se resolvió fácilmente con el uso de lociones queratolíticas. Las vainas peripilares son una modificación estructural del cabello. Son unas masas de queratina que envuelven el tallo piloso. Instrumentos sencillos, como una lupa, pueden ayudarnos a distinguirlas de su principal diagnóstico diferencial, la Pediculosis capitis(AU)
We describe the case of a female patient with hair casts due to her hairstyle (a pulled-back ponytail). The problem was solved very easily with keratolytic lotions. Hair casts are a structural variation of the hair. They are keratin accretions encircling a segment of the hair shaft. They must be differentiated from pediculosis capitis with simple tools such as a magnifying glass(AU)

El edema agudo hemorrágico de la infancia (EAHI) es una forma poco frecuente de vasculitis leucocitoclástica. Normalmente ocurre en niños menores de dos años. Se caracteriza por la aparición brusca de edema y lesiones purpúricas dianiformes, fundamentalmente en cara y extremidades. A pesar de esta presentación tan dramática, su naturaleza es benigna, con afectación sistémica excepcional y resolución completa de las lesiones de forma espontánea. El principal diagnóstico diferencial es con la púrpura de Schölein-Henoch. Describimos un caso clásico de EAHI en un niño de 10 meses después de un cuadro infeccioso de vías respiratorias altas tratado con antibióticos. Presentamos este caso para incidir en la naturaleza benigna de este proceso (AU)
Acute hemorrhagic edema of infancy (AHEI) is an unusual form of leukocytoclastic vacuities. It usually occurs in children younger than 2 years of age. It is characterized by the acute development of edema and targetoid purpuric lesions mainly on the face and extremities. Despite its dramatic onset, has benign nature with uncommon visceral involvement and spontaneous complete recovery. The main differential diagnosis in Henoch-Schölein purpura. We describe a classic case of AHEI in a ten-month old boy occurred after upper respiratory tract infection and antibiotic treatment. We report this case to emphasize the benign course of this disorder (AU)
