Congenital intracranial tumors are rare and account for 0.5 to 1.5% of all childhood tumours. We report
a case of a 3 week old baby presenting with multi compartmental congenital intracranial immature
teratoma, fi rst of its kind in the literature. The child had gross total excision in two stages with aid of
neuronavigation. The short term outcome was good. The four years of follow-up with serial imaging
showed no tumour recurrence with a stable hydrocephalus after shunting. However, there is global
developmental delay with full time dependence of care giver

A new technique for single spore isolation was developed for predacious fungi forming constricting rings directly on the spores using Dactylaria brochopaga and Arthrobotrys dactyloides. Constricting rings were induced directly on the spores by transferring the spores in 25 ppm solution of DL-Valine in sterile distilled water. Freshly hatched and thoroughly washed second stage juveniles of Meloidogyne incognita were transferred into cavity blocks containing induced rings for trapping and killing of nematodes. The killed nematodes were surface sterilized with streptomycin and inoculated into petri dishes containing maize meal agar media with 100 ppm streptomycin. The petri dishes were incubated at 29+/-1degrees C for few days which yielded axenic culture of these fungi.

Prospective diagnostic imaging study. The stability of the thoracic and lumbar spine depends significantly on the posterior ligamentum complex (PLC). Therefore, it is essential to diagnose PLC injuries accurately before deciding on a treatment plan for thoracolumbar injury patients. However, the efficacy of magnetic resonance imaging (MRI) in diagnosing PLC remains undetermined. MRI has become the ultimate tool in diagnosing spine injury cases, as previous literature suggests that it has very high sensitivity and specificity. But this is still controversial and as many surgeons rely on just MRI for selecting the patient for surgery, it becomes important to know the diagnostic accuracy of it. Patients who sustained injuries from T1 to L3 and required posterior surgery were prospectively studied. The treating surgeon and musculoskeletal radiologist participating in the study reviewed preoperative MRI images to characterize the level(s) of injury and the integrity of the six components of the PLC. These were classified as intact, incompletely disrupted, or disrupted. During the surgical procedure, the surgeon also classified each component of the PLC, and the radiologist’s and surgeon’s findings were compared. Out of 66 patients, 46 were males (69.7%) and 20 were females (30.3%), and the average age was 34.12 years. According to the kappa score, there was a moderate level of agreement between the radiologist’s interpretation and the intraoperative findings for all PLC components except for the thoracolumbar fascia and ligamentum flavum for which there was a slight agreement. The sensitivity for the intact PLC components ranged from 100% (supraspinous ligament) to 66.67% (ligamentum flavum). The specificity ranged from 100% (interspinous ligament) to 52% (thoracolumbar fascia). The Spearman’s rank correlation ranged from 0.061 for the thoracolumbar fascia to 0.918 for the interspinous ligament, and the percentage agreement ranged from 81.82% (interspinous ligament to 36.36% (thoracolumbar fascia). The sensitivity and specificity of MRI for diagnosing injury of the PLC in this study were lower than those previously reported in the literature. The integrity of the PLC as determined by MRI should not be used in isolation to determine treatment.

Purpose:
Uncertainty exists about whether early laparoscopic cholecystectomy (LC) is an appropriate surgical treatment for acute calculous cholecystitis. This study aimed to compare early vs. late LC for acute calculous cholecystitis regarding intraoperative difficulty and postoperative outcomes.
Methods:
This was a prospective randomized study carried out between December 2015 and June 2017; 60 patients with acute calculous cholecystitis were divided into two groups (early and delayed groups), each comprising 30 patients. Thirty patients treated with LC within 3 to 5 days of arrival at the hospital were assigned to the early group. The other 30 patients were placed in the delayed group, first treated conservatively, and followed by LC 3 to 6 weeks later.
Results:
The conversion rates in both groups were 6.7% and 0%, respectively (p = 0.143). The operating time was 56.67 ± 11.70 minutes in the early group and 75.67 ± 20.52 minutes in the delayed group (p = 0.001), and both groups observed equal levels of postoperative complications. Early LC patients, on the other hand, required much fewer postoperative hospital stay (3.40 ± 1.99 vs. 6.27 ± 2.90 days, p = 0.006).
Conclusion
Considering shorter operative time and hospital stay without significant increase of open conversion rates, early LC might have benefits over late LC.

OBJECTIVETo investigate antimicrobial and bronchodialator effect of hydroalcholic extract of polyherbal drug Shirishadi containing Shirisha (Albezzia lebbeck), Nagarmotha (Cyprus rotandus) & Kantakari (Solanum xanthocarpum).
METHODSAntimicrobial activity was evaluated by disc diffusion method and MIC, MBC, MFC were calculated by micro dilution method. Hydroalcholic extract of this preparation was investigated for its phytochemical analysis, phenol and flavonoid were determined by spectrophotometric method and in vivo bronchodilator effect was analysed by convulsion time.
RESULTSThe phytochemical tests revealed presence of alkaloids, anthraquinones, carbohydrates, flavonoids, saponins and tannins. The antimicrobial result showed the MIC of 6.25 mg/mL against Staphylococcus aureus and 12.5 mg/mL for Escherichia coli and 12.5 mg/mL against remaining bacteria tested, with strong antifungal activity. The maximum inhibition zone is found against Pseudomonas aeruginosa with MIC 16 mg/mL. Drug showed significant bronchodilator effect with 27.86% & 36.13% increase in preconvulsion time of guinea pigs pretreated with 100 & 200 mg/kg body weight of extract.
CONCLUSIONSThe study reveals that the extracts possess antibacterial activity and antifungal activity in a dose dependent manner. This antimicrobial property may be due to presence of several saponins, further studies are highly needed for the drug development.
