    Background: Antibiotics are the mainstay treatment of most of the infectious diseases. Inappropriate and irrational use of antimicrobial agents has led to increase in the development of antimicrobial resistance. Medical students are a part of health care system and they must be aware of increasing antibiotic resistance as they are the future prescribers. The objectives of the study were to assess the awareness on antibiotic usage and its resistance among medical students and to study the perception on antibiotic medication among medical students.Methods: This was a cross-sectional, semi-structured questionnaire-based study. Questionnaire consists of 4 parts- socio-demographic details, awareness on antibiotics and its resistance, knowledge on specific treatment of a disease, perception levels. Prior IEC approval was taken. The obtained data was statistically analyzed using Microsoft excel sheet.Results: Among 230 participants, majority of the students have awareness on general antibiotic usage and 97.8% were having knowledge about antibiotic resistance. The main source of information on antibiotic resistance is identified as classroom teaching (67.8%). 46.9% and 25.2% students correctly identified the drug of choice for treating enteric fever and community acquired pneumonia respectively.Conclusions: Degrees of awareness on antibiotics and its resistance is found to be good. Antibiotic usage pattern is not on par with knowledge. Knowledge on specific treatment of infectious disease is found to be less. So, antibiotic teaching should be integrated with clinical subjects

    Interplay between n-3 and n-6 long-chain polyunsaturated fatty acids and the endocannabinoid system in brain protection and repair.

    The brain is enriched in arachidonic acid (ARA) and docosahexaenoic acid (DHA), long-chain polyunsaturated fatty acids (LCPUFA) of the n-6 and n-3 series, respectively. Both are essential for optimal brain development and function. Dietary enrichment with DHA and other long-chain n-3 PUFA, such as eicosapentaenoic acid (EPA) have shown beneficial effects on learning and memory, neuroinflammatory processes and synaptic plasticity and neurogenesis. ARA, DHA and EPA are precursors to a diverse repertoire of bioactive lipid mediators, including endocannabinoids. The endocannabinoid system comprises cannabinoid receptors, their endogenous ligands, the endocannabinoids, and their biosynthetic and degradation enzymes. Anandamide (AEA) and 2-archidonoylglycerol (2-AG) are the most widely studied endocannabinoids, and are both derived from phospholipid-bound ARA. The endocannabinoid system also has well established roles in neuroinflammation, synaptic plasticity and neurogenesis, suggesting an overlap in the neuroprotective effects observed with these different classes of lipids. Indeed, growing evidence suggests a complex interplay between n-3 and n-6 LCPUFA and the endocannabinoid system. For example, long-term DHA and EPA supplementation reduces AEA and 2-AG levels, with reciprocal increases in levels of the analogous endocannabinoid-like DHA and EPA-derived molecules. This review summarises current evidence of this interplay and discusses the therapeutic potential for brain protection and repair

    Current status of robotic single-port surgery

    Robotic-assisted laparoscopic surgery in urology is an ever progressing field, and boundaries are constantly broken with the aid of new technology. Advancements in instrumentation have given birth to the era of robotic laparoendoscopic single-site technique (R-LESS). R-LESS however, has not gained widespread acceptance due to technical hurdles such as adequate triangulation, robotic arm clashing, decreased access for the bedside assistant, lack of wrist articulation, continued need for an axillary/accessory port, lack of robust retraction, and ergonomic discomfort. Many innovations have been explored to counter such limitations. We aim to give a brief overview of a history and development of R-LESS urologic surgery and outline the latest advancements in the realm of urologic R-LESS. By searching PubMed selectively for relevant articles, we concluded a literature review. We searched using the keywords: robotic laparoscopic single incision, robotic laparoendoscopic single-site, single incision robotic surgery, and R-LESS. We selected all relevant articles in that pertained to single-site robotic surgery in urology. We selected all relevant articles that pertained to single-site robotic surgery in urology in a table encompassed within this article. The development of the R-LESS procedures, instrumentations, and platforms has been an evolution in progress. Our results showed the history and evolution toward a purpose-built single-port robotic platform that addresses previous limitations to R-LESS. Even though previous studies have shown feasibility with R-LESS, the future of R-LESS depends on the availability of purpose-built robotic platforms. The larger concern is the demonstration of the definitive advantage of single-site over the conventional multiport surgery

    Minimally Invasive Management of Ureteral Distal Strictures: Robotic Ureteroneocystostomy With a Bilateral Boari Flap

    Objective: To describe robotic ureteroneocystostomy performed by bilateral Boari flap. Methods: An 82-year-old female with bilateral mid ureteral strictures secondary to uterine cancer treated with radiation was managed with ureteral stenting and bilateral nephrostomy tubes. Nevertheless, patient had severe colic and recurrent urinary tract infections and thus agreed to undergo bilateral robotic ureteral reconstructive surgery. Patient positioning and ports placement were similar to those of robotic prostatectomy. Ureters were divided at the level of the common iliac bifurcation and mobilized proximally. Strictures were excised and ureters were spatulated. After the bladder was dropped from the abdominal wall, a bladder flap was created with a broad base to ensure adequate blood supply. The ureteral anastomosis to the bladder flap was started using 3-0 Vicryl interrupted sutures to secure the posterior ureter to the bladder flap. The flap was then bisected in the midline to create a tension-free anastomosis. The ureteral anastomosis was completed over a double J ureteral stent. The wings of the bisected bladder flap were reapproximated with a 3-0 barbed suture to form a "Y" bladder configuration. Procedures were done bilaterally. The remainder of the cystotomy was closed with barbed suture. The bladder was tested for leakages and a drain was placed. Results: Blood loss was 50 mL. The patient recovered uneventfully and was discharged on postoperative day 4 with nephrostomy tubes and Jackson-Pratt drain removed prior to discharge. Follow-up cystogram revealed no leakage and bilateral reflux in the reconstructed bladder. Ureteral stents were removed 4 weeks postoperatively. Follow-up for these patients is recommended with either a renal scan or CT scan with delayed imaging. For this patient with severe chronic kidney disease, she unfortunately could not receive intravenous contrast and renal scan proved unreliable. Therefore, our follow-up was performed on the basis of her renal function (creatinine) which remained stable without nephrostomies or ureteral stents. Postoperatively, the patient did not complain of de novo lower urinary tract symptoms nor did she require anticholinergics. Conclusion: Robotic bilateral Boari flap is feasible for patients with bilateral distal ureteral strictures. Further studies are needed to assess long-term outcomes. Given the significant degree of bladder reconstruction required for this procedure, we recommend an assessment of bladder capacity preoperatively in the form of a gravity cystogram or video urodynamics
