Objetivo: Determinar la asociación entre la obstrucción intestinal y la cirugía de urgencia en el adulto mayor en el Hospital Santa Rosa durante el 2014– 2015. Material y métodos: Se realizó un estudio retrospectivo, transversal, analítico relacional. De 784 pacientes ≥ 60 años atendidos en el servicio de cirugía general por patologías abdominales, se revisó 156 historias clínicas y reportes operatorios de pacientes sometidos a cirugía abdominal de urgencia y de ellos 57 presentaron obstrucción intestinal. Además se determinó la asociación y frecuencia de las variables clínico-epidemiológicas: sexo, edad, antecedentes quirúrgicos, comorbilidades; hallazgos operatorios y tipo de procedimiento quirúrgico. Resultados: El 36.54% presentó obstrucción intestinal, que a su vez constituye un factor de riesgo (OR=3.58, p=0.000) para cirugía abdominal de urgencia; así mismo, se halló para el sexo femenino (OR=0.55, p=0.092); edad >65 años (OR=3.81, p=0.000); antecedentes quirúrgicos (OR=38.5, p=0.000); presencia de comorbilidades complicadas (OR=5.38, p=0.004); hipertensión arterial: 43.9%, diabetes mellitus tipo 2: 33.3%; el hallazgo operatorio: bridas y adherencias obtuvo un 73.7%, igual que la liberación de bridas y adherencias como procedimiento quirúrgico realizado. Conclusiones: La obstrucción intestinal, edad, presencia de comorbilidades complicadas y antecedentes quirúrgicos están asociadas y constituyen un factor de riesgo para cirugía abdominal de urgencia en el paciente adulto mayor. El hallazgo operatorio más frecuente fue las bridas y adherencias; las comorbilidades más frecuentes fueron la hipertensión arterial y diabetes mellitus tipo 2 y el procedimiento quirúrgico más realizado fue la liberación de bridas y adherencias.

A dissertation submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master in Pharmacy. Johannesburg, South Africa, 2006 / The aqueous extract of rooibos has been used for more than three hundred years since its discovery by the indigenous people. Currently, rooibos is gaining popularity in the cosmetic industry and incorporation of rooibos extracts in topical cosmetic formulations has become a fashionable trend. Both topical and intestinal absorption of rooibos tea were investigated. The transport of aspalathin in the unfennented (green) rooibos aqueous extracts and aqueous solution of pure aspalathin were studied. / IT2018

Celiac disease is a small intestinal immune-mediated enteropathy precipitated by exposure to gluten, a protein complex in the cereals wheat, barley and rye, in genetically susceptible people. Once considered an uncommon disorder restricted to children of European descent, it is now known to be one of the most common chronic diseases encountered in the Western world, with a serological prevalence of 1% that can be diagnosed at any age. Since it is so common much co-morbidity comprising malignant and non-malignant conditions will occur in association. Malignant complications particularly lymphoma were first described over 50 years ago but the natural history and how commonly these occurred were unknown until relatively recently. Similarly, many non-malignant conditions were known to occur but initially the risks were unclear. It was not until the frequency of coeliac disease could be determined accurately in the community and population-based studies of morbidity and mortality in coeliac disease patients carried out in defined cohorts that these questions could be answered. My research into these aspects of coeliac disease began in 1971 and a body of 35 of my publications spanning the years 1974 to 2018 on the morbidity and mortality of the disorder are presented in this thesis. I have introduced my research findings at many international and national meetings and these data have been influential in shaping the research agenda of other workers. One of my papers (Publication 9) published in Gut in 1989, was the most cited of all papers which appeared in the journal for that year. To date it has been cited 1122 times. Information exists for 24 papers presented here and for these the total number of citations stands at 3,887. This excludes references to book chapters. Anecdotal evidence indicates frequent mentions in lectures and clinical practice.
