The history of lobotomy as a neuropsychiatric intervention in Brazil - a case report of a geriatric patient.

Lobotomy was a widespread neurosurgical procedure in the first half of the 20th century. It was used as a treatment for various mental disorders. The development of psychosurgeries in Brazil, their indications, effects, consequences, advancements, as well as the social context of the population subjected to it are revised herein.

Strategic use of 4 % deltamethrin impregnated-collar in seropositive dogs reduces the incidence of seroreactivity to visceral leishmaniasis in dogs from endemic areas.

The effectiveness of a visceral leishmaniasis (VL) control strategy based on the application of 4 % deltamethrin impregnated collars (DIC) exclusively in seropositive dogs was assessed between 2018 and 2019, through a prospective study. The effectiveness of DIC-collaring was evaluated by comparing the incidence rate of anti-leishmanial antibodies among dogs from two endemic districts in Brazil. In one of the areas, the conventional control measure which is based on the non-compulsory euthanasia of LV seropositive dogs, was practiced by the official healthy service as a regular procedure, whereas strategic collaring, conceived in this study, was carried out in the other.

Lipoprotein glomerulopathy associated with the Osaka/Kurashiki APOE variant: two cases identified in Latin America.

Background: Lipoprotein glomerulopathy (LPG) is a rare autosomal dominant disease caused by mutations in APOE, the gene which encodes apolipoprotein E. LPG mainly affects Asian individuals, however occasional cases have also been described in Americans and Europeans. Herein we report two unrelated Brazilian patients with LPG in whom genetic analyses revealed the APOE-Osaka/Kurashiki variant.

Glucocorticoid resistance in dialysis patients reduces long-term graft survival after kidney transplantation.

Glucocorticoid (GC) resistance has been observed in chronic kidney disease (CKD) patients on dialysis. It can be evaluated by binding assays based on the dissociation constant (Kd), which is inversely proportional to ligand affinity. CKD patients with GC resistance had increased number of acute rejection episodes.

Molecular epidemiology of Staphylococcus aureus isolates at different sites in the milk producing dairy farms.

The epidemiological relationships between isolated Staphylococcus aureus strains in milk samples of dairy cows, reagent to California Mastitis Test, individual and group milk was demonstrated in different sites of the production fluxogram, in 12 milk-producing farms in the Gameleira region, municipality of Sacramento MG Brazil, so that localization and transmission modes may be identified. Two hundred and forty-four strains out of 446 samples collected at several sites were isolated and bio-chemically characterized as coagulase-positive staphylococcus. Specific chromosome DNA fragment of the species Staphylococcus aureus was amplified to 106 strains and 103 underwent (PFGE).

Glucocorticoid resistance in dialysis patients may impair the kidney allograft outcome.

This study examines in vitro steroid sensitivity in chronic renal failure (CRF) patients and its influence on the allograft outcome. We determined the inhibitory effect of dexamethasone (DEX) on concanavalin A (Con-A)-stimulated peripheral blood mononuclear cell (PBMC) proliferation, and glucocorticoid receptor' (GR) number of binding sites (B(max)) and affinity (K(d)) in 28 CRF patients and 40 normal healthy controls. Based on K(d) values >95th percentile from controls, patients were divided into two groups: glucocorticoid resistant (n = 11) and glucocorticoid sensitive (n = 17).
