International audience; The characteristics of hydrocephalus associated with cerebellar glioblastoma (cGB) remain poorly known. The objectives were to describe the occurence of hydrocephalus in a French nationwide series of adult patients with cGB, to identify the characteristics associated with hydrocephalus and to analyze the outcomes associated with the different surgical strategies, in order to propose practical guidelines. Consecutive cases of adult cGB patients prospectively recorded into the French Brain Tumor Database between 2003 and 2017 were screened. Diagnosis was confirmed by a centralized neuropathological review. Among 118 patients with cGB (mean age 55.9 years), 49 patients (41.5%) presented with pre-operative hydrocephalus. Thirteen patients (11.0%) developed acute (n=7) or delayed (n=6) hydrocephalus postoperatively. Compared to patients without hydrocephalus at admission, patients with hydrocephalus were younger (52.0 years vs 58.6 years, p=0.03) and underwent more frequently tumor resection (93.9% vs 73.9%, p=0.006). A total of 40 cerebrospinal-fluid diversion procedures were performed, including 18 endoscopic third ventriculostomies, 12 ventriculoperitoneal shunts and 10 external ventricular drains. The different cerebrospinal-fluid diversion options had comparable functional results and complication rates. Among the 89 patients surgically managed for cGB without prior cerebrospinal-fluid diversion, 7 (7.9%) were long-term shunt-dependant. Hydrocephalus is frequent in patients with cGB and has to be carefully managed in order not to interfere with adjuvant oncological treatments. In case of symptomatic hydrocephalus, a cerebrospinal-fluid diversion is mandatory, especially if surgical resection is not feasible. In case of asymptomatic hydrocephalus, a cerebrospinal-fluid diversion has to be discussed only if surgical resection is not feasible.

Fenugreek seeds (Trigonella foenum-graecum L.) are an old herbal remedy used to treat metabolic and nutritive dysfunctions. They have been shown to modulate feeding behaviour in animals, but strong clinical data are lacking. The aim of this study was to investigate the effects of a repeated administration of a fenugreek seed extract on energy intake and eating behaviour in healthy human volunteers.Twelve healthy male volunteers completed a double-blind randomized placebo-controlled three-period cross-over trial of two different doses of a fenugreek seed extract (588 and 1176 mg). The three 14-day treatment periods were separated by a 14-day washout period. The main endpoints were energy intake, assessed in volunteers under normal ambulatory and free-living conditions by a 3-day detailed dietary record and during a meal test, weight, fasting glucose level, insulin and lipid profile, visual analogue scale scores of appetite/satiety and blood glucose and insulin levels measured repeatedly after a standardized breakfast.Daily fat consumption was significantly decreased by the higher dose of fenugreek seed extract [3.73 vs. 4.51 MJ day(-1), -17.3% vs. placebo, 95% confidence interval (CI) -1.51 to -0.05, n = 12, P = 0.038]. This specific reduction tended to lower the total energy intake (9.97 vs. 11.29 MJ day(-1), -11.7% vs. placebo, 95% CI -2.91 to 0.26, n = 12, P = 0.094). No significant effect was observed on the other nutrients or other endpoints.The repeated administration of a fenugreek seed extract specifically decreases dietary fat consumption in humans which, given the traditional use of the plant, constitutes a novel result.
