Persistent disorders of mineral metabolism after one year of kidney transplantation.

Introduction:: The persistence of mineral metabolism disorders after renal transplant (RT) appears to possess a negative impact over graft and patient's survival.

Objectives:: To evaluate the parameters of mineral metabolism and the persistence of hyperparathyroidism (HPT) in transplanted patients for a 12-month period after the procedure.

Methods:: Retrospective analysis of 41 transplants (18 women- 44%, mean age of 39 ± 15 years) performed in a University Hospital, evaluating changes of calcium (Ca), phosphorus (P) and parathyroid hormone (PTH) and the prevalence of persistent HPT.

Mechanism for the acute effects of organophosphate pesticides on the adult 5-HT system.

The neurotransmitter serotonin (5-HT) is involved in mood disorder aetiology and it has been reported that (organophosphate) OP exposure affects 5-HT turnover. The aim of this study was to elucidate the mechanism underlying OP effects on the adult 5-HT system. First, acute in vivo administration of the OP diazinon (0, 1.

Non-palpable breast lesions marked with coal suspension: evaluation of anatomopathological aspects, viability of interpretation and inflammatory response.

Objective: To analyze the efficiency of labeling impalpable breast lesions with inert charcoal suspension; to evaluate the morphological alterations associated with its use and to determine whether the use of charcoal labeling hampers the diagnostic interpretation of the pathologist.

Methods: Was evaluated a total of 135 cases of impalpable breast lesions previously labeled with charcoal suspension. Histological H&E stained slides containing charcoal pigments were analyzed using optical microscopy, by which both quantitative and qualitative evaluations with regards to inflammatory response and interference in diagnosis were performed.
