Human rabies is a fatal encephalomyelitis. After the development of the central nervous system infection, there is centrifugal spread of the rabies virus to extraneural (systemic) organs. With histochemical staining and localization of rabies virus antigen (RVA) with immunoperoxidase staining, we have examined tissue sections of organs from 14 postmortem(More)
Sling left pulmonary artery (SLPA) is often associated with tracheobronchial abnormalities, including bridging bronchus (BB). We report on 3 patients with SLPA: One patient had a narrow trachea, absent right upper lobe and right main bronchus, and BB. The second patient had a long and narrow trachea, with normal segmentation of bronchial tree, abnormal(More)
Ameloblastoma is the most frequent odontogenic tumor and is considered a benign, but locally invasive, neoplasm with variable clinico-pathological expression. Syndecan-1 is a cell surface proteoglycan that binds cells to the extracellular matrix and its expression is down-regulated in many cellular transformation models. The aims of this study were to(More)
A 23-month-old girl with Osler-Weber-Rendu (OWR) disease manifested by hemoptysis died of massive pulmonary hemorrhage. Autopsy showed predominant respiratory tract involvement, but telangiectatic vessels were also present in other sites. Skin lesions were absent. A grandfather had died after bleeding by mouth following physical exertion. This disease(More)
BACKGROUND AND AIMS The relative frequency and risk factors of portopulmonary hypertension in children have not been defined with precision. The few published reports refer to isolated cases or small series from selected populations. The development of pulmonary hypertension in patients with portal hypertension is seldom suspected or documented during life.(More)
We cared for 124 pediatric patients with a histologic diagnosis of Langerhans' cell histiocytosis (histiocytosis X) over a period of 14 years. Clinical, laboratory, and radiographic findings were analyzed. The most frequent manifestations were bone lesions, lymph node involvement, and skin infiltration. Liver disease was noted in 50% of patients and lung(More)
Infection by Mycobacterium bovis is not infrequently identified in Mexico. Its relation to nonpasteurized milk products ingestion is well recognized with primary infection usually in the intestinal tract. The term "abdominal tuberculosis" includes peritoneal as well as primary and secondary intestinal tuberculosis. The clinical differentiation of these(More)
Formalin-fixed intestinal tissue specimens from 12 Mexican pediatric patients with intussusception were examined for the presence of adenovirus. Four patients (33%) had detectable adenovirus antigen in epithelial cells as determined by using immunohistochemical analysis. Two of the patients with positive immunohistochemical results had antigens in dendritic(More)
Induction of bone tissue requires three elements: osteoprogenitor cells, osteoinductive factors, and a supporting extracellular matrix. In this study, we report on an experimental model in dogs of heterotopic bone tissue production, based on the integration of these osteo-inductive factors into abdominal implants. The implants consist of either a type I(More)
