Dopamine agonists are the treatment of choice for prolactinomas. However, there are still controversies concerning dose, treatment duration and criteria for drug withdrawal in different clinical situations. The aim of this study was to assess diagnostic and therapeutic approaches to prolactinomas among members of the Brazilian Society of Endocrinology and Metabolism (SBEM).

Aims: To compare high-sensitivity C-reactive protein (hsCRP) in HIV-infected patients treated or not with antiretroviral (ARV) drugs and to correlate hsCRP levels with traditional cardiovascular risk factors and parameters of HIV infection.

Methods: One hundred and seventy-one HIV-infected patients were included (129 ARV-treated and 42 ARV-naïve). Evaluations included anthropometric measurements, blood pressure, laboratory tests, ultrasonographic measurement of fat thickness and impedance analysis.

Background/aim: The mode of action of the somatostatin analog octreotide on neuro-endocrine tumour proliferation is largely unknown. Overexpression of the proto-oncogene Akt/PKB (protein kinase B) has been demonstrated in certain neuro-endocrine tumours: Akt activates downstream proteins including mTOR and p70S6K, which play an important role in cell proliferation. RAD001 (everolimus) is a novel agent that is being trialled in the treatment of neuro-endocrine tumours, and is known to interact with mTOR.

The histiocytoses are rare diseases caused by alterations in the monocyte-histiocytic series with several clinical findings. Among the cutaneous syndromes of non-Langerhans cells, xanthoma disseminatum is the only disease of this group that has been classically associated to the central diabetes insipidus (CDI). The case reported describes a 30-year-old man that two years after presenting with CDI developed non confluent disseminated cutaneous brown papular lesions throughout the body.

Aims: To compare the intra-abdominal fat thickness measured by ultrasound between HIV-infected patients treated or not with antiretroviral drugs and to correlate these visceral adiposity measurements to other parameters of cardiovascular risks.

Methods: In a transversal observational study, 160 HIV-infected patients were recruited and divided in two groups, i.e.

Background: Gestational diabetes mellitus (GDM) is not merely a temporary condition, but a harbinger of type 2 diabetes mellitus, hypertension, and atherosclerotic disease. We examined the effect of GDM on cardiac diastolic function.

Methods: Diastolic function was evaluated by serial Doppler echocardiography with pulsed tissue Doppler imaging in 13 patients with GDM and 13 healthy pregnant women (control group) during the third trimester of pregnancy and after 8 weeks postpartum.
