Case Reports[Inferior vena cava agenesis presenting as deep vein thrombosis. Report of one case].
Abnormalities of the inferior vena cava are rare. Its embryological development occurs between the sixth and eighth week of gestation and depends on the persistence or regression of three pairs of veins: the posterior cardinal veins, the subcardinal veins and the supracardinal veins. The type of congenital alteration depends on the moment that embryogenesis is altered. ⋯ An abdominal CAT scan showed an agenesis of the supra and infra-adrenal inferior vena cava, with multiple collaterals. The study for thrombophilia was negative. The patient was treated with vitamin K antagonists with a good clinical response.

Case Reports[Methemoglobinemia caused by dapsone. Report of one case].
Methemoglobinemia is a rare condition with serious consequences if not diagnosed. We report the case of a 64-year-old woman with a history of allergy to sulfa drugs and a recent diagnosis of a small vessel vasculitis (ANCA-p) who started induction therapy with corticosteroids and rituximab. Due to the need for infectious prophylaxis, and considering her history, dapsone was administered instead of cotrimoxazole after ruling out glucose-6-phosphate dehydrogenase deficiency. ⋯ The arterial gasometric study by direct potentiometry revealed an O2 saturation of 98%, with a saturation gap > 5%. Considering the use of dapsone, a methemoglobinemia was suspected and confirmed by co-oximetry (methemoglobinemia 9%). Dapsone was suspended and one week later, her methemoglobinemia was absent.

Social frailty is a seldom explored concept in older people. There is dissent if it should be considered a multidimensional syndrome or it should be limited to the physical sphere. ⋯ One exposes the concept of social frailty, nine operationalize social frailty using questions or items on social behavior and two use scales or measuring instruments to classify older people as "socially frail". It is concluded that social frailty is a new concept in gerontology: there are divergences as to whether it should be considered as another dimension of frailty or as an independent concept with a predictive capacity by itself to detect risk among older people.

This work addresses the controverted reproductive health policies in the last fifty years in the United States and in the last thirty years in Chile, since the return of democracy. They range from the inclusion of sex education programs in school curricula to the voluntary interruption of pregnancy and the recent emergence of institutional conscientious objection. The author provides a comparative analysis of the latter in both countries, considering the current political context in the United States and the constituent process development in Chile.
