ABSTRACT

We present a case of an unusual cause of ulnar pain on a 9-year-old patient. The patient had pain on the ulnar side of the wrist after a fall. MRI showed a poorly defined lesion on the ulnar nerve at Guyon's canal. The initial diagnosis was traumatic neuropathy. Following conservative treatment of symptoms for one year, the pain started again. Therefore, a new MRI was performed where progression of the lesion was observed. Excision of the lesion was performed and the specimen sent for pathologic analysis. The diagnosis was of microcystic lymphatic malformation. The patient had a satisfactory evolution, with complete resolution. This is the first description of a microcystic lymphatic malformation in an intraneuronal location.

ABSTRACT

Los agentes de revelado fotográfico son derivados de la parafenilendiamina, que pueden actuar como irritantes y/o sensibilizantes cutáneos en trabajadores de procesos fotográficos, manifestándose las lesiones no sólo en forma de eczema de contacto, sino también como lesiones liquenoides. La incidencia de dermatosis profesionales por reveladores de color ha disminuido en los últimos años debido a la automatización de los procesos de revelado y a la aparición de la fotografía digital. Presentamos un caso de dermatitis de contacto liquenoide secundaria al revelador CD2 en un trabajador de laboratorio fotográfico automatizado que ocasionalmente reparaba las averías que se presentaban en la maquinaria. Las lesiones eran clínica e histológicamente liquenoides y las pruebas epicutáneas resultaron positivas a CD2. Nuestro caso presenta además la particularidad de la diseminación de las lesiones hacia zonas donde no era evidente el contacto con el líquido revelador


Colour developing agents, derivatives of paraphenylendiamine, can be both irritants and sensitizers in photographic processing workers. They cause allergic contact dermatitis and also lichenoid reactions. The incidence of occupational dermatosis from colour developers has decreased in the last years because of the automation in the developer processing and the emergence of digital photography. We present a case of lichenoid contact dermatitis in a mechanized photographic laboratory worker, who occasionally repaired machinery's damages. Lesions were clinical and histhopatological lichenoid and patch test were positives to CD2. Our case presents the singularity of the dissemination of the lesions to areas of the skin where it was not evident the contact with the colour developers agents

ABSTRACT

OBJECTIVE: Portal hypertension as an inducer of intestinal inflammatory response would cause epithelial and splanchnic vascular remodeling in the long-term. This experimental study was carried out to verify this hypothesis. METHOD: Structural alterations characteristic of intestinal epithelial and mesenteric vascular remodeling, the density of goblet cells and the diameter of mesenteric vein branches were studied, respectively, in rats with partial portal vein ligation in the short (1 month) and long-term (1 year). RESULTS: Hyperplasia of goblet cells in the small intestine (duodenum, jejunum, ileum) is maximum after 1 year of evolution of the portal hypertension and is associated with dilatation of the distal branches (3rd and 4th order) of the superior mesenteric vein. CONCLUSION: Long-term splanchnic remodeling in experimental portal hypertension suggests the existence of a chronic inflammatory process in this clinical condition.

ABSTRACT

Objetivo: La hipertensión portal, en tanto que inductora de una respuesta inflamatoria intestinal, causaría a largo plazo remodelación epitelial y vascular esplácnicas. Con el objeto de verificar esta hipótesis se ha realizado éste trabajo experimental. Método: Se han estudiado como alteraciones estructurales propias de remodelación epitelial intestinal y vascular mesentérica la densidad de células caliciformes y el diámetro de las ramas de la vena mesentérica, respectivamente, en ratas con ligadura parcial de la vena porta a corto (1 mes) y largo (1 año) plazo. Resultados: La hiperplasia de células caliciforrnes en intestino delgado es máxima al año de evolución de la hipertensión portal y se asocia con dilatación de las ramas distales (3er y 4° orden) de la vena mesentérica superior. Conclusión: La remodelación esplácnica que ocurre a largo plazo en la hipertensión portal experimental sugiere la existencia de un proceso inflamatorio crónico en ésta patología

ABSTRACT

OBJECTIVE: Demonstrate the role of the virulence factors of Helicobacter pylori, the sex, and tobacco and alcohol use in the development of peptic ulcer in patients infected by H. pylori. PATIENTS AND METHODS: One hundred and seventy-four patient with dyspepsia were studied after they went consecutively for gastroscopy. The diagnosis of infection by H. pylori was carried out by culture and/or histology. Through western-blot the presence of specific anti-H. pylori antibodies was determined. The tobacco and alcohol use data were collected. RESULTS: One hundred and twenty-five patients (32 with ulceration, 12 with duodenitis and 81 with functional dyspepsia) showed H. pylori infection with anti-bacterium IgG antibodies. The detection of the proteins CagA and VacA, male sex and heavy consumption of alcohol and tobacco were associated with the finding of peptic ulcer. In the multivariate analysis only anti-CagA antibodies (OR: 4.1; 95% CI: 1.1-15.3; p = 0.036), anti-VacA (OR: 3.9; 95% CI: 1.4-10.8; p = 0.009) and male sex (OR: 3.1; 95% CI: 1.2-8.3; p = 0.02) were associated with the ulcerative disease. CONCLUSIONS: The proteins CagA and VacA, and the male sex, contribute independent risk factors for peptic ulcer in patients infected by H. pylori.

ABSTRACT

Objetivo. Determinar el papel de los factores de virulencia de Helicobacter pylori, el sexo y el consumo de tabaco y alcohol en el desarrollo de úlcera péptica en pacientes infectados por H. pylori. Pacientes y métodos. Se estudiaron 174 pacientes dispépticos que acudieron consecutivamente a realizarse una gastroscopia. El diagnóstico de infección por H. pylori se realizó por cultivo y/o histología. La presencia de anticuerpos específicos anti-H. pylori se determinó mediante western-blot. Se recogió el consumo de tabaco y alcohol. Resultados. Ciento veinticinco pacientes (32 con úlcera, 12 con duodenitis y 81 con dispepsia funcional) fueron diagnosticados de infección por H. pylori con anticuerpos IgG frente a la bacteria. La detección de las proteínas CagA y VacA, el sexo masculino y el consumo elevado de alcohol y tabaco se asociaron con el hallazgo de úlcera péptica. En el análisis multivariante sólo los anticuerpos anti-CagA (odds ratio [OR]: 4,1; intervalo de confianza [IC] 95 por ciento: 1,1-15,3; p = 0,036), anti-VacA (OR: 3,9; IC 95 por ciento: 1,4-10,8; p = 0,009) y el sexo masculino (OR: 3,1; IC 95 por ciento: 1,2-8,3; p = 0,02) se asociaron con la enfermedad ulcerosa. Conclusiones. Las proteínas CagA y VacA y el sexo masculino contribuyen de manera independiente al riesgo de padecer úlcera péptica en pacientes infectados por H. pylori (AU)

ABSTRACT

Primary Effusion Lymphoma is an unusual entity and it has been described as a subset associated with human herpes virus 8 infection in homosexual males with AIDS. Its inclusion as a new entity in the Revised European-American Lymphoma Classification has been recommended. The case in which it is presented is a 47-year-old man, diagnosed with AIDS two years ago, who came with Kaposi's sarcoma. Nowadays, he has a right pleural effusion and a thoracentesis has been carried out. We obtain 10 ml of haemorrhagic fluid which is processed by standard methods. The morphologic study reveals a non-Hodgkin's lymphoma of high-grade. The immunophenotypic study shows a lymphoid neoplasm of indeterminate lineage and high proliferation index. It confirms the HHV-8 in the neoplastic cells by PCR. The diagnosis is a non-Hodgkin's lymphoma of high-grade compatible with Primary Effusion Lymphoma.

ABSTRACT

El linfoma primario de cavidades es una rara entidad, habiéndose descrito un subgrupo asociado a infección por HHV-8 en varones homosexuales con Sida, recomendándose su inclusión como una nueva entidad en la Clasificación Revisada Europea-Americana de los Linfomas. El caso que se presenta es el de un varón de 47 años, diagnosticado de Sida hace dos, que debutó con sarcoma de Kaposi. En la actualidad, se presenta con un derrame pleural derecho y se realiza toracocentesis. Se obtienen 10ml de un líquido hemorrágico, que se procesa de forma rutinaria. El estudio morfológico revela un linfoma no Hodgkin de alto grado. El estudio inmunofenotípico pone de manifiesto una neoplasia de estirpe linfoide, de línea indeterminada y de alto índice proliferativo. Se confirma la infección por HHV-8 en las células neoplásicas, mediante PCR. El diagnóstico es linfoma no Hodgkin de alto grado compatible con linfoma primario de cavidades (AU)
