Jessner's Lymphocytic Infiltration of the Skin in a 73-Year-Old Woman: A Case Report.

BACKGROUND Jessner's lymphocytic infiltration of the skin (JLIS) is a rare and benign process of unknown cause. This disorder affects both sexes, most commonly in the young adult population. However, the demographic characteristics remain largely unknown, due to limited information. JLIS clinical presentation is heterogeneous; lesions can be indurated papular or erythematous plaques on the upper body. Symptoms are variable, from asymptomatic to pruritus and burning sensation. CASE REPORT A female patient aged 73 years presented with 10-day asymptomatic dermatosis on the left malar area after an insect sting. At the beginning, the lesion was clinically classified as an abscess and antibiotic therapy was prescribed with ciprofloxacin 500 mg every 12 hours for 5 days. However, due to the lack of clinical response, a biopsy was performed, which reported a predominantly lymphocytic nodular dermatitis. JLIS diagnosis was confirmed after laboratory and imaging tests. Intralesional infiltrations of triamcinolone (0.5 ml) twice within 15 days and mineral sunscreen 3 times a day were prescribed. After the treatment, the lesion had a complete resolution without recurrence to date. CONCLUSIONS The present case reports JLIS in an older woman who presented a complete healing resolution of the lesion without recurrences after triamcinolone intralesional infiltrations and sunscreen protection.

Activity of soluble aminopeptidase A and dipeptidyl peptidase IV and membrane-bound aminopeptidase B and pyroglutamyl peptidase I in adenoid hyperplasia, tonsillar hyperplasia and chronic tonsillitis.

OBJECTIVE: To analyze soluble and membrane-bound peptidase activities in the tonsils and adenoids removed from patients with adenoid hyperplasia, tonsillar hyperplasia and chronic tonsillitis. METHODS: A total of 48 tissue samples from patients undergoing adenoidectomy and tonsillectomy for adenoid hyperplasia, tonsillar hyperplasia or chronic tonsillitis were analyzed. The catalytic activity of a pool of peptidases in the soluble (dipeptidyl peptidase IV, aminopeptidase A, aminopeptidase N and cystinyl aminopeptidase) and membrane-bound (prolyl endopeptidase, aspartyl aminopeptidase, aminopeptidase B and pyroglutamyl peptidase I) fractions was measured fluorometrically. RESULTS: The activity of membrane-bound aminopeptidase B was higher in cases of chronic tonsillitis and adenoid hyperplasia than in tonsillar hyperplasia, p=0.004. Soluble dipeptidyl peptidase IV and membrane-bound pyroglutamyl peptidase I were found to be more active in tissues from male chronic tonsillitis tissues, p<0.05, while membrane-bound aminopeptidase B activity was higher in tissues of females with tonsillar hyperplasia, p<0.001. In the case of chronic tonsillitis, soluble aminopeptidase A was found to have a higher level of activity in tissues from children than those from adults, p=0.005. CONCLUSIONS: Our results suggest a potential role of soluble aminopeptidase A, soluble dipeptidyl peptidase IV, membrane-bound aminopeptidase B and membrane-bound pyroglutamyl peptidase I in the pathobiology of adenoid hyperplasia, tonsillar hyperplasia and chronic tonsillitis that is differently regulated as a function of gender. These finfings may modify in the future the clinical approach to these diseases.

Diagnostico de absceso hepatico amibiano por prueba de difusion en agar: un metodo simple y eficiente con antigeno no axenico / Diagnosis of amoebic liver abcess by the agar cell diffusion test: a simple and efficient method with non axenic antigens

El diagnostico de absceso hepatico amibiano es frecuentemente dificil. Por este motivo se han adaptado muchas prueba serologicas para amibiasis pero por diversas razones (costos altos, falta de equipo especial y de personal entrenado) no se pueden emplear en la mayoria de los paises en desarrollo. Los autores realizaron dos pruebas de difusion en agar donde se comparan dos antigenos solubles de Entamoeba histolytica, uno preparado con amibas locales que se cultivaron en el medio modificado de Boeck y Drbohlav (difasico) con flora fecal y otro con trofozoitos de E. histolytica cultivados axenicamente. En los 38 sueros que se estudiaron (22 de personas con absceso hepatico amibiano, 6 de pacientes con otras enfermedades y 10 de controles sanos) mediante la difusion con gel de agar se obtuvieron resultados identicos al utilizar ambos antigenos. Estos hallazgos sugieren que el antigeno local es confiable y puede constituir en los paises en desarrollo una alternativa adecuada para el serodiagnostico del absceso hepatico amibiano
