ABSTRACT
BACKGROUND: There is still a debate regarding the most appropriate pleural collector model to ensure a short hospital stay and minimum complications. OBJECTIVES: To study aimed to compare the time of air leak, time to drain removal, and length of hospital stay between a standard water-seal drainage system and a pleural collector system with a unidirectional flutter valve and rigid chamber. DESIGN AND SETTING: A randomized prospective clinical trial was conducted at a high-complexity hospital in São Paulo, Brazil. METHODS: Sixty-three patients who underwent open or video-assisted thoracoscopic lung wedge resection or lobectomy were randomized into two groups, according to the drainage system used: the control group (WS), which used a conventional water-seal pleural collector, and the study group (V), which used a flutter valve device (Sinapi® Model XL1000®). Variables related to the drainage system, time of air leak, time to drain removal, and time spent in hospital were compared between the groups. RESULTS: Most patients (63%) had lung cancer. No differences were observed between the groups in the time of air leak or time spent hospitalized. The time to drain removal was slightly shorter in the V group; however, the difference was not statistically significant. Seven patients presented with surgery-related complications: five and two in the WS and V groups, respectively. CONCLUSIONS: Air leak, time to drain removal, and time spent in the hospital were similar between the groups. The system used in the V group resulted in no adverse events and was safe.

ABSTRACT
BACKGROUND AND OBJECTIVES: Ventriculoperitoneal shunt (VPS) is usually the primary choice for cerebrospinal fluid shunting for most neurosurgeons, while ventriculoatrial shunt (VAS) is a second-line procedure because of historical complications. Remarkably, there is no robust evidence claiming the superiority of VPS over VAS. Thus, we aimed to compare both procedures through a meta-analysis. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, the authors systematically searched the literature for articles comparing VAS with VPS. The included articles had to detail one of the following outcomes: revisions, infections, shunt-related mortality, or complications. In addition, the cohort for each shunt model had to encompass more than 4 patients. RESULTS: Of 1872 articles, 16 met our criteria, involving 4304 patients, with 1619 undergoing VAS and 2685 receiving VPS placement. Analysis of revision surgeries showed no significant difference between VAS and VPS (risk ratio [RR] = 1.10, 95% CI: 0.9-1.34; I2 = 84%, random effects). Regarding infections, the analysis also found no significant difference between the groups (RR = 0.67, 95% CI: 0.36-1.25; I2 = 74%, random effects). There was no statistically significant disparity between both methods concerning shunt-related deaths (RR = 2.11, 95% CI: 0.68-6.60; I2 = 56%, random effects). Included studies after 2000 showed no VAS led to cardiopulmonary complications, and only 1 shunt-related death could be identified. CONCLUSION: Both methods show no significant differences in procedure revisions, infections, and shunt-related mortality. The literature is outdated, research in adults is lacking, and future randomized studies are crucial to understand the profile of VAS when comparing it with VPS. The final decision on which distal site for cerebrospinal shunting to use should be based on the patient's characteristics and the surgeon's expertise.
ABSTRACT
Objective Programmable valves provide an equal or superior neurological outcome when compared with fixed pressure ones, with fewer complications, in treating idiopathic normal pressure hydrocephalus (iNPH) patients. Long-term costs of these treatments have not been properly compared in literature. We sought to compare costs, efficacy, and safety of 1-year treatment of iNPH patients with programmable valve Sphera Pro and a fixed pressure valve. Materials and Methods A prospective cohort of iNPH patients treated with programmable valve was compared with a historical cohort of iNPH patients treated with fixed pressure valve. Our primary outcome was mean direct cost of treating iNPH up to 1 year. Efficacy in treating iNPH and safety were assessed as secondary outcomes. Statistical Analysis Proportions were compared using chi-square or Fisher's exact tests. Normally distributed variables were compared using the Student's t -test or the Mann-Whitney's U test. Differences in the evolution of the variables over time were assessed using generalized estimating equations. All tests were two-sided, with an α of 0.05. Results A total of 19 patients were analyzed in each group (mean age 75 years, the majority male). Comorbidities and clinical presentation were similar between groups. Both fixed pressure and programmable valve patients had neurological improvement over time ( p < 0.001), but no difference was seen between groups ( p = 0.104). The fixed pressure valve group had more complications than the programmable valve group (52.6% vs. 10.5%, respectively, p = 0.013). Annual treatment cost per patient was US$ 3,820 ± 2,231 in the fixed pressure valve group and US$ 3,108 ± 553 in the programmable valve group. Mean difference was US$712 (95% confidence interval, 393-1,805) in favor of the programmable valve group. Conclusion The Sphera Pro valve with gravitational unit had 1 year treatment cost not higher than that of fixed pressure valve, and resulted in similar efficacy and fewer complications.
ABSTRACT
Background: Normal pressure hydrocephalus is a disease directly related to the change in intracranial compliance and consequent repercussions in the brain parenchyma. Invasive monitoring of such parameters proves to be reliable especially for prognosis in neurocritical patients; however, it is not applicable in an outpatient service setting. The present study describes the comparison between the tap test results and the parameters obtained with a non-invasive sensor for monitoring intracranial compliance in patients with suspected NPH. Methods: Twenty-eight patients were evaluated before and after lumbar puncture of 50mL of CSF (the tap test), comprising clinical assessment, magnetic resonance imaging, physical therapy assessment using the Timed Up and Go test, Dynamic Gait Index, BERG test, neuropsychological assessment, and recording of non-invasive intracranial compliance data using the Brain4care® device in three different positions (lying, sitting, and standing) for 5 min each. The tap test results were compared to the Time to Peak and P2/P1 ratio parameters obtained by the device. Results: The group that had a positive Tap test result presented a median P2/P1 ratio greater than 1.0, suggesting a change in intracranial compliance. In addition, there was also a significant difference between patients with positive, negative, and inconclusive results, especially in the lying position. Conclusion: A non-invasive intracranial compliance device when used with the patient lying down and standing up obtained parameters that suggest correspondence with the result of the tap test.
ABSTRACT
Hemangioblastomas (HBs) of the brain may present without neurological symptoms over a long period of time due to their benignity and slow growth. We herein present the case of a female patient who developed a HB of the fourth ventricle presenting only with severe weight loss and anorexia. The patient was screened for mutations in all 3 exons of the VHL gene using Sanger sequencing, and was found to have a nonsense mutation in the VHL gene (single-nucleotide change causing a premature stop codon: c.481C>T; p.Arg161*), causing formation of a truncated protein, consistent with von Hippel-Lindau syndrome (VHLs). The patient was first misdiagnosed with anorexia nervosa (AN) due to the lack of other symptoms. Molecular diagnosis allows further investigation of other VHLs-related tumors and timely, appropriate treatment. However, misdiagnosing anorexia nervosa may lead to poor prognosis and even death; thus, differential diagnosis is crucial in all such cases. The present case report provides evidence that fourth ventricular lesions may affect food intake control and satiety, and highlights the importance of accurate molecular diagnosis.
ABSTRACT
OBJECTIVE: To identify or use alcohol abuse and abuse in the IAMSPE elderly, through the application of AUDIT, socioeconomic characterization of the elderly, and problems associated with drinking and weight, if there is a relationship between depression and alcohol abuse. METHODS: This is a cross-sectional, exploratory, and descriptive study with a quantitative approach. One hundred elderly patients were interviewed to apply a socioeconomic form and to assess alcohol consumption from AUDIT. RESULTS: correlation between alcohol consumption and female gender (p = 0.021). Most of the participants were between 60 and 79 years old, were female, had a partner, had completed elementary school, had income and selected house, were retired and unemployed. CONCLUSION: In the present study, we found no correlation between alcohol abuse and depression; Only one correlation was found between male gender and higher alcohol abuse. However, a significant prevalence of moderate use of high alcohol was found (3.9% in women and 21.7% in men), i.e., it poses a risk to the health of the elderly.

INTRODUCTION: Cerebral hydrodynamics complications in shunted patients are due to the malfunction of the system. The objective of this retrospective, single-center, single-arm cohort study is to confirm the safety and performance of Sphera® Duo when used in adult patients suffering from hydrocephalus, pseudotumor cerebri or arachnoid cysts. METHODS: Data were generated by reviewing 112 adult patient's charts, who were submitted to a ventriculoperitoneal shunt surgery and followed for one year after surgery. RESULTS: The results show us that 76% of patients had their neurological symptoms improved and that the reoperation rate was 15% in the first year following surgery. DISCUSSION: Sphera Duo® shunt system is an applicable shunt option in routine neurosurgical management of hydrocephalus by several causes. It has presented good results while mitigating effects of overdrainage. Overdrainage is especially important in adults with non-hypertensive hydrocephalus and can cause functional shunt failure, which causes subnormal ICP (particularly in the upright position) and is associated with characteristic neurological symptoms, such as postural headache and nausea. CONCLUSION: Sphera Duo® shunt system is safe when used in adult patients suffering from hydrocephalus, pseudotumor cerebri or arachnoid cyst.

Resumo Introdução: As complicações da hidrodinâmica cerebral em pacientes com derivação ventriculoperitoneal são frequentemente relacionadas ao malfuncionamento do sistema. O objetivo deste estudo retrospectivo de coorte de centro único é avaliar a segurança e performance clínica do Sistema Sphera® Duo quando utilizado em adultos com hidrocefalia, pseudotumor cerebral ou cistos aracnoides. Métodos: Avaliamos os prontuários de 112 pacientes adultos submetidos a cirurgia de derivação ventriculoperitoneal e acompanhados por 1 ano após a cirurgia. Resultados: O resultado mostra que 76% dos pacientes melhoraram dos sintomas neurológicos e a taxa de reoperação foi de 15% no primeiro ano após a cirurgia. Discussão: O sistema de derivação Sphera Duo® é uma opção de shunt adequada a ser usada no tratamento neurocirúrgico da hidrocefalia por causas diversas. Ele demonstrou bons resultados clínicos enquanto reduziu riscos de hiperdrenagem. A hiperdrenagem é especialmente preocupante e mórbida em pacientes adultos com hidrocefalia não hipertensiva e pode levar a prejuízo clínico e disfunção da válvula, com sintomas de hipotensão craniana, como cefaléia ortostática e náuseas. Conclusão: O sistema de derivação Sphera Duo® é seguro para tratamento da hidrocefalia, pseudotumor cerebri ou cistos aracnóides em adultos.

ABSTRACT Objective: To present a program of home physical exercises for patients with normal pressure hydrocephalus (NPH) and to evaluate adherence, acceptance and applicability; to verify possible changes in patients with NPH in the home physical exercise program, comparing patients with, and without, a ventriculoperitoneal shunt, regarding gait, quality of life, activities of daily living, static and dynamic balance and its impact on the risks of falling. Methods: This was a controlled clinical trial, with assessments in three moments (0, 10 and 18 weeks) at the home, from October 2015 to November 2017. Fifty-two patients (30 women and 22 men) participated in the study. Results: There was a statistically significant improvement with 10 weeks of home physical exercises for the groups with and without ventriculoperitoneal shunt, respectively, in the sub-items: activities of daily living p = 0.032*, p = 0.003*; static balance p < 0.001*, p < 0.001*; functional capacity p < 0.001*, p = 0.027*; and dynamic balance and gait p = 0.009*, p < 0.001*. There was no statistically significant difference for the subitems: quality of life p = 0.695, p = 1.000; and NPH grading scale p = 0.695, p = 1.000, respectively. Conclusion: The developed program of home physical exercise was easily applied and there was good acceptance by most patients with NPH included in the research. There was a statistically significant improvement with the 10 weeks of home physical exercises in the sub-items: activities of daily living, static balance and functional capacity, for both groups. In the sub-item dynamic balance and gait, there was a statistically significant improvement for both groups, but with a higher score for the group with a ventriculoperitoneal shunt. There was no statistically significant difference for the sub-items: quality of life, NPH grading scale and risk of falls, based on the Berg scale.

OBJECTIVE: The current study translated to Portuguese and validated the normal pressure hydrocephalus (NPH) scale originally developed in English as the Grading Scale for Idiopathic Normal Pressure Hydrocephalus. METHODS: Following Guillemin's validation protocol, the last version of the Portuguese NPH scale was applied to 121 consecutive patients with a diagnosis of normal pressure hydrocephalus (73 men and 48 women) from the Group of Cerebral Hydrodynamics from July 2010 to March 2012. RESULTS: The mean age was 71.09 years old, ranging from 35 to 92 years. The rate of agreement and reproducibility was high, as confirmed by Cohen's Kappa coefficient, with excellent intraobserver correlation for the NPH scale items individually evaluated: gait (0.80), dementia (0.90) and incontinence (0.87). CONCLUSIONS: The Portuguese version of the Grading Scale for Idiopathic Normal Pressure Hydrocephalus was successfully translated and validated for use in Brazilian patients.

Cholangiocarcinoma accounts for less than 2% of all malignant neoplasms. Its cutaneous metastases are extremely rare, accounting for 0.0002% of all cases. The ventriculoperitoneal (VP) shunt has been considered a potential route for tumor dissemination. This type of tumor proliferation has been well documented in patients with intra-abdominal metastases secondary to brain tumors and, less frequently, brain metastases secondary to intra-abdominal tumors. In spite of that, there are few reports of cutaneous metastases along the VP shunt catheter trajectory. We present the case of a cholangiocarcinoma cutaneous metastasis at the VP shunt trajectory as the first clinical sign of this type of tumor. The patient had undergone the shunt insertion 4 years earlier due to a hydrocephaly secondary to a subarachnoid hemorrhage. After diagnosis, she was referred to chemotherapy and oncology follow-up. In the literature, 30 cases of cutaneous metastasis of cholangiocarcinoma were reported. Dissemination has been described involving percutaneous biliary drainage and distant sites. However, the case presented in this study alerts us about the possibility of cutaneous metastasis of intra-abdominal tumors in the trajectory of VP shunt catheters.
O colangiocarcinoma representa menos de 2% das neoplasias malignas. Sua metástase cutânea é extremamente rara, representando 0.0002% dos casos. A derivação ventrículo-peritoneal (DVP) tem sido considerada uma via potencial para a disseminação dos tumores. Essa propagação tumoral já foi bem descrita em pacientes com tumores do sistema nervoso central e metástases intra-abdominais e, menos frequentemente, em metástases cerebrais secundárias a tumores intra-abdominais. Apesar disso, a presença de metástases cutâneas ao longo da trajetória do cateter de DVP é pouco relatada. Apresentamos o caso de uma paciente portadora de DVP há quatro anos devido a uma hidrocefalia secundária à hemorragia subaracnoide e que apresentou metástases cutâneas de colangiocarcinoma na trajetória do cateter de derivação como o primeiro sinal clínico do tumor. Após o diagnóstico, ela foi encaminhada para quimioterapia e acompanhamento com oncologia. Na literatura, foram relatados 30 casos de metástases cutâneas de colangiocarcinoma. Em geral, a disseminação pode envolver locais distantes ou cateteres de drenagem biliar percutânea. No entanto, o caso descrito neste estudo nos alerta sobre a possibilidade de metástases cutâneas de tumores intra-abdominais na trajetória de cateteres de DVP.

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 Público Estadual de São 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.

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 prosthetic material. 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.
Introdução A derivação ventriculosinusal retrógrada (DVSR) deve ser uma opção na rotina de neurocirurgiões que trabalham com hidrodinâmica. O objetivo deste estudo é revisar os principais dados sobre DVSR. Métodos Realizamos uma revisão crítica. As palavras-chave usadas foram hydrocephalus shunt, venous sinus, ventriculosinus shunt, retrograde ventriculosinus shunt, e sagittal sinus. A busca foi feita nas bases de dados Medline (Pubmed) e EMBASE. Resultados Van Canneyt et al (2008) e Pinto et al (2016) realizaram estudos experimentais confirmando a eficiência do DVSR. El Shafei et al (1985, 1987, 2001) relataram vários casos tratados com eficiência e poucas complicações. Oliveira et al (2015, 2016) compararam DVSR e derivação ventriculoperitoneal (DVP) no tratamento de hidrocefalia após reparo de mielomeningocele em crianças, obtendo resultados funcionais similares. Oliveira et al (2015, 2016) também descreveram a aplicabilidade do DVSR em situações em que o DVP não é possível, ou o peritônio é hostil. Discussão A DVSR é uma opção segura e mais fisiológica, que requer menos material protético; é factível e aplicável. Particularmente em crianças, gera um estado normotenso após o shunt, permitindo crescimento cefálico centrífugo, uma vez que não há mais hipotensão intracraniana devido à hiperdrenagem, o que pode refletir em melhor desenvolvimento psicomotor em longo prazo. Conclusões A técnica cirúrgica DVSR é viável. Os resultados clínicos se são comparáveis à DVP.
