    The Timed Up and Go Test as a Diagnostic Criterion in Normal Pressure Hydrocephalus
    (2017) MENDES, Gabriel Andre Silva; OLIVEIRA, Matheus Fernandes de; PINTO, Fernando Campos Gomes
    INTRODUCTION: Normal-pressure hydrocephalus (NPH) is a disease characterized by gait disturbance, urinary incontinence, and dementia. Our objectives were to define an average value of the test for the population, check the specificity and test sensitivity as evaluation criteria and diagnostic testing, and correlate with other already used more frequently. METHODS: A study conducted at the Neurosurgery Division of the Hospital do Servidor Publico Estadual de Sao Paulo in which a group of 30 patients with NPH was submitted to the Mini-Mental State Test Examination, Time Up and Go (TUG), test and Japanese scale for NPH before the Tap Test 3 hours and 72 hours after the Tap Test. After being subjected to ventriculoperitoneal shunt, patients were evaluated 3 months, 6 months, and 12 months after surgery. A control group was used composed of 30 individuals of the same age and who had no diagnosis of NPH who were submitted to the TUG test to determine an average, which was compared with that of patients with NPH. RESULTS: TUG did not show good correlation with other tests used, but there was excellent specificity (0.967) and sensitivity (0.933) for cut-off value of 16.5 seconds for the diagnosis of NPH. CONCLUSIONS: TUG is a good test for the diagnosis of NPH because there is very good specificity and sensitivity, with a mean value of 16.5 seconds as the cut-off.

    Revisiting Retrograde Ventriculosinus Shunt as an Alternative for Treating Hydrocephalus in Children
    (2017) OLIVEIRA, Matheus Fernandes; TEIXEIRA, Manoel Jacobsen; OLIVEIRA, Marcelo Lima; SHU, Edson Bor Seng; PINTO, Fernando Campos Gomes
    Introduction Retrograde ventriculosinus shunt (RVSS) is a useful option in the daily routine of neurosurgeons dealing with hydrodynamics. The objective of this manuscript is to review the main data about RVSS. Methods We performed a critical review. The keywords used were hydrocephalus, shunt, venous sinus, ventriculosinus shunt, retrograde ventriculosinus shunt, and sagittal sinus. The search was performed in the Medline (Pubmed) and EMBASE databases. Results Van Canneyt et al (2008) and Pinto et al (2016) performed experimental studies confirming the effectiveness of RVSS. El Shafei et al (1985, 1987, 2001) authors reported several cases treated with efficacy and few complications. Oliveira et al (2015, 2016) compared RVSS and ventriculoperitoneal shunt (VPS) in the treatment of hydrocephalus after myelomeningocele repair in infants, with similar functional results. Oliveira et al (2015, 2016) also described the applicability of RVSS in situations when VPS is not feasible, or when the peritoneum is not useful. Discussion Retrograde ventriculosinus shunt is a safe and more physiological option, which requires the use of less prostheticmaterial. It is feasible and applicable. Especially in children, it generates a normotensive state after shunting, allowing centrifugal head growth, once there is no intracranial hypotension due to overdrainage, which may reflect in long-term better psychomotor development. Conclusions The surgical technique of RVSS is feasible. The clinical results are comparable with those of the VPS.
