Neurocysticercosis is the commonest parasitic disease of the human central nervous system. The incidence of intra ventricular form of neurocysticercosis (NCC) is less common accounting 10-20% that of total central nerve system cysticercosis. Intra ventricular NCC is complicated due, to its high incidence of acute hydrocephalus caused by ball valve mechanism. The only reliable tool for diagnosis of NCC is by neuroimaging with CT or MRI. MRI preferred over CT because of its high specificity and sensitivity. In emergency situations like acute hydrocephalus one can proceed with emergency endoscopic surgery. Through the endoscopic view, intra ventricular NCC (IVNCC) has distinguished morphological features like the full moon sign. This feature not only helps in identification of IVNCC, but also guides in further endoscopic treatment strategy. Authors report two cases of 3rd ventricular NCC with acute hydrocephalus managed with emergency endoscopy. Authors have discussed the clinical features, intra operative endoscopic findings and role of endoscopy in emergency surgery for NCC with acute hydrocephalus.

Objective: To investigate the effect of Foeniculum vulgare extract against lipopolysaccharide (LPS)-induced microglial activation in vitro as well as cognitive behavioral deficits in mice. Methods: LPS-activated BV-2 cell viability was measured using MTT assay and reactive oxygen species (ROS) was studied using DCF-DA assay. The antioxidative enzymes and pro-inflammatory mediators were analyzed using respective ELISA kits and Western blotting. For in vivo testing, LPS (1 mg/kg, i.p. ) was given daily for five days in male Swiss albino mice to produce chronic neuroinflammation. Cognitive and behavioral tests were performed using open-field, passive avoidance, and rotarod experiments in LPS-induced mice. Results: Foeniculum vulgare extract (25, 50 and 100 μg/mL) significantly attenuated the LPS-activated increase in nitric oxide (NO), ROS, cyclooxygenase-2, inducible NO synthase, IL-6, and TNF-alpha (P < 0.05). Moreover, LPS-induced oxidative stress and reduced antioxidative enzyme levels were significantly improved by Foeniculum vulgare extract (P < 0.05). The extract also regulated the NF-κB/MAPK signaling in BV-2 cells. In an in vivo study, Foeniculum vulgare extract (50, 100, and 200 mg/kg) markedly mitigated the LPS-induced cognitive and locomotor impairments in mice. The fingerprinting analysis showed distinctive peaks with rutin, kaempferol-3-O-glucoside, and anethole as identifiable compounds. Conclusions: Foeniculum vulgare extract can ameliorate LPS-stimulated neuroinflammatory responses in BV-2 microglial cells and improve cognitive and locomotor performance in LPS-administered mice.
