Gastric cancer (GC) is a highly heterogenic disease, and it is the second leading cause of cancer death in the world. Common chemotherapies are not very effective for GC, which often presents as an advanced or metastatic disease at diagnosis. Treatment options are limited, and the prognosis for advanced GCs is poor. The landscape of genomic alterations in GCs has recently been characterized by several international cancer genome programs, including stud-ies that focused exclusively on GCs in Asians. These studies identiifed major recurrent driver mutations and provided new insights into the mutational heterogeneity and genetic proifles of GCs. An analysis of gene expression data by the Asian Cancer Research Group (ACRG) further uncovered four distinct molecular subtypes with well-deifned clini-cal features and their intersections with actionable genetic alterations to which targeted therapeutic agents are either already available or under clinical development. In this article, we review the ACRG GC project. We also discuss the implications of the genetic and molecular ifndings from various GC genomic studies with respect to developing more precise diagnoses and treatment approaches for GCs.

OBJECTIVETo assess the interobserver agreement on Garden classification of fresh femoral neck fracture and management plan based on anteroposterior (AP) view and also assess if the addition of lateral view changes the classification and management plan.
METHODSTen orthopaedic surgeons were asked to classify 35 femoral neck fractures on AP view only and propose the management plan. Then the same films were reshown in conjunction with their lateral view after 10 days. Results were compared with respect to the classification and management plan between two groups. Interobserver agreement was calculated using Fleiss' kappa.
RESULTSThere was only a fair interobserver agreement (kappa value 0.39) on Garden classification on AP view only which improved to moderate agreement (kappa value 0.52) after adding a lateral view. While there was only a slight improvement in the interobserver agreement on the management plan on AP view only (kappa value 0.50) and AP combined with lateral views (kappa value 0.52). Supplementation of the lateral view changed the classification in 15.42% of the cases and altered the management plan in 23.14% of the cases.
CONCLUSIONWe conclude that lateral view should be obtained routinely on all patients with suspected femoral neck fracture as it definitely has a role in planning treatment of femoral neck fracture.

Curcumin (diferuloylmethane) is a yellow pigment present in the spice turmeric (Curcuma longa) that has been associated with antioxidant, anti-inflammatory, anticancer, antiviral, and antibacterial activities as indicated by over 6,000 citations. In addition, over one hundred clinical studies have been carried out with curcumin. One of the major problems with curcumin is perceived to be the bioavailability. How curcumin should be delivered in vivo, how bioavailable is it, how well curcumin is absorbed and how it is metabolized, is the focus of this review. Various formulations of curcumin that are currently available are also discussed.

Objective:Polycystic ovary syndrome(PCOS)is a pathophysiological disorder affecting reproductive and metabolic indices in females.The present study was designed to compare the efficacy of metformin and D-chiro-inositol in PCOS patients.Methods:In a tertiary care hospital in North India,prospective observational research was undertaken on 100 patients with PCOS,which was diagnosed based on European Society of Human Reproduction and Embryology Guidelines and ultrasound of lower abdomen.The study involves various clinical characteristics into considera-tion for the determination of statistical significance(P<0.05)in PCOS patients.Student's t-test along with the association between PCOS and patients taking metformin and D-chiro-inositol,as well as their impact on various biochemical parameters,were investigated finally using Pearson Correlation Analysis.Results:This study comprises 50 patients taking metformin and 50 patients taking D-chiro-inositol in women suffering from PCOS.Body mass index(BMI)and waist-to-hip ratio(WHR)were statistically significant(P<0.05)within the groups of both metformin and D-chiro-inositol.Biochemical parameters such as luteinizing hormone(LH),follicle stimulating hormone(FSH),anti-mullerian hormone(AMH)and glycated hemoglobin(HbA1c)were found to be statistically significant(P<0.05)in both groups.LH,FSH and AMH(14.40±0.52;14.28±0.53;1.99±0.10)were comparatively lower in patients taking D-chiro-inositol as compared to metformin group(14.17±0.42;19.88±1.01;2.61±0.04).HbA1c(3.71±0.08)with P<0.05 was found to be decreased more in metformin group as compared to patients taking D-chiro-inositol(4.90±0.09).A positive correlation was found between HbA1c and LH in metformin,& HbA1c and FSH in D-chiro-inositol groups,respectively.Conclusion:The results indicate that D-chiro-inositol shows better results in reducing clinical variables involved in causing PCOS as compared to metformin whereas metformin has better glycemic control in PCOS patients.

We reported a case of a 32 years old male presenting with a perforating gunshot injury in craniocerebral region 3 h after the assault. The bullet entered above the right zygomatic arch, travelling through the coronal plane, and exited from the left zygomatic arch. The patient was fully conscious at presentation and developed facial nerve palsy during his hospital stay. Non-contrast CT scan of the head revealed fractures of the right orbit, bilateral maxilla, bilateral pterygoid plates, ethmoid air cells, vomer and left zygoma, and without any cerebral damage. He was treated conservatively and the facial palsy was resolved. The patient survived without any complications. Such case has not been described in the available literature till date.
