BACKGROUND: Adipose tissue accumulation in specific body compartments has been associated with diabetes, hypertension and dyslipidemia. Perirenal fat (PRF) may lead to have direct lipotoxic effects on renal function and intrarenal hydrostatic pressure. This study was undertaken to explore the association of PRF with cardiovascular risk factors and different stages of chronic kidney disease (CKD). METHODS: We studied 103 patients with CKD of different stages (1 to 5). PRF was measured by B-mode renal ultrasonography in the distal third between the cortex and the hepatic border and/or spleen. RESULTS: The PRF thickness was greater in CKD patients with impaired fasting glucose than in those with normal glucose levels (1.10 ± 0.40 cm vs. 0.85 ± 0.39 cm, P < 0.01). Patients in CKD stages 4 and 5 (glomerular filtration rate [GFR] < 30 mL/min/1.73 m²) had the highest PRF thickness. Serum triglyceride levels correlated positively with the PRF thickness; the PRF thickness was greater in patients with triglyceride levels ≥ 150 mg/dL (1.09 ± 0.40 cm vs. 0.86 ± 0.36 cm, P < 0.01). In patients with a GFR < 60 mL/min/1.73 m², uric acid levels correlated positively with the PRF thickness (P < 0.05). CONCLUSION: In CKD patients, the PRF thickness correlated significantly with metabolic risk factors that could affect kidney function.

Craniocerebral gunshot injuries (CGI) are increasingly encountered by neurosurgeons in civilian and urban settings. Unfortunately this is a prevalent condition in developing countries, with major armed conflicts which is not very likely to achieve a high rate of prevention. Management goals should focus on early aggressive, vigorous resuscitation and correction of coagulopathy; those with stable vital signs undergo brain computed tomography scan. Neuroimaging is vital for surgical purposes, especially for determine type surgery, size and location of the approach, route of extraction of the foreign body; however not always surgical management is indicated, there is also the not uncommon decision to choose non-surgical management. The treatment consist of immediate life salvage, through control of persistent bleeding and cerebral decompression; prevention of infection, through extensive debridement of all contaminated, macerated or ischemic tissues; preservation of nervous tissue, through preventing meningocerebral scars; and restoration of anatomic structures through the hermetic seal of dura and scalp. There have been few recent studies involving penetrating craniocerebral injuries, and most studies have been restricted to small numbers of patients; classic studies in military and civil environment have identified that this is a highly lethal or devastating violent condition, able to leave marked consequences for the affected individual, the family and the health system itself. Various measures have been aimed to lower the incidence of CGI, especially in civilians. It is necessarily urgent to promote research in a neurocritical topic such as CGI, looking impact positively the quality of life for those who survive.

Historically, obesity has been identified as one of the most important risk factors for developing cardiovascular diseases including stroke; however, a theory called “The Obesity Paradox” has been recently considered. The paradoxical theory is that obese or overweight patients (according to body mass index score) can have better outcomes compared to leaner or malnourished patients. The paradox was initially discovered in patients with heart failure. The purpose of this manuscript was to investigate whether this paradox also applies to stroke patients, according to information available in the current literature.

Flow diverters have become a critical instrument for complex aneurysms treatment. However, limited data are currently available regarding short and long-term outcomes for the Silk flow diverter. The objective of the study is to determine neurological prognosis and mortality rates for the Silk flow diversion device used in intracranial aneurysms. A systematic review with meta-analysis was performed using databases. The following descriptors were used for the search: “SILK”, “Flow Diverter”, “Mortality”, and “Prognosis”. The following data were extracted: mortality, good functional outcome, Glasgow outcome scale, complete or near-complete occlusion rates, rate of retreatment, and complications (thromboembolic and hemorrhagic complications). A total of 14 studies were selected. Among the 14 studies, 13 were retrospective observational cohort studies and 1 was a prospective observational cohort study. The mortality rate was 2.84%. The clinical good outcomes rate was 93.3%. The poor outcome rate was 6.6%. The overall thromboembolic complication rate was 6.06% (95% confidence interval [CI] 0.00–6.37, P=0.12, I2=3.13%). The total hemorrhagic complication rate was 1.62% (95% CI 0.00–5.34, P=0.28, I2=1.56%). The complete aneurysm occlusion rate was 80.4% (95% CI 8.65–9.38, P<0.0001, I2=9.09%). The Silk diverter device has a good safety and efficacy profile for treating intracranial aneurysms with high complete occlusion rates.
