This document contains a chapter summary on the inflammatory response and sepsis as well as sample multiple choice questions that test understanding of the key concepts. It discusses that sepsis affects over 1 million people in the US each year and that cytokines are small hormone-like proteins secreted by cells that mediate inflammation. Recombinant human activated protein C has been approved by the FDA for treatment of severe sepsis.
Difficult Laparoscopic Cholecystectomy-When and Where is the Need to Convert?Apollo Hospitals
Laparoscopic cholecystectomy has now become the treatment of choice for the gall bladder stone. With increasing experience, surgeon has started to take more difficult cases which were considered relative contra indications for laparoscopic removal of gall bladder few years back.
We conducted this study at our hospital and included all laparoscopic cholecystectomy done from May'08 to January'10. Total time taken in surgery, conversion rate and complication rate were analysed. Factors making laparoscopic cholecystectomy difficult were also analysed. We defined difficult laparoscopic cholecystectomy when we found -dense fibrotic adhesions in and around Callot's triangle, gangrenous gall bladder, empyma, large stone impacted at gall bladder neck, contracted gall bladder, Mirrizi's syndrome, h/o biliary pancreatitis, CBD stones, acute cholecystitis of <72 hrs duration.
Out of 206 cases done during above period, 56 cases were considered difficult. Only two cases were converted to open.
With growing experience and technical advancement surgery can be completed in most of the difficult cases. This is important because recently it is shown in literature that laparoscopic cholecystectomy is associated with less morbidity than open method irrespective of duration of the surgery.

The incidence of biliary injury after laparoscopic cholecystectomy (LC) has shown a declining trend though it may still be twice that as with open cholecystectomy. Major biliary or vasculobiliary injury is associated with significant morbidity. As prevention is the best strategy, the concept of a culture of safe cholecystectomy has been recently introduced to educate surgeons and apprise them of basic tenets of safe performance of LC. Various aspects of safe cholecystectomy include: (1) thorough knowledge of relevant anatomy, various anatomical landmarks, and anatomical variations; (2) an understanding of the mechanisms involved in biliary/vascular injury, the most important being the misidentification injury; (3) identification of various preoperative and intraoperative predictors of difficult cholecystectomy; (4) proper gallbladder retraction; (5) safe use of various energy devices; (6) understanding the critical view of safety, including its doublet view and documentation; (7) awareness of various error traps (e.g., fundus first technique); (8) use of various bailout strategies (e.g., subtotal cholecystectomy) in difficult gallbladder cases; (9) use of intraoperative imaging techniques (e.g., intraoperative cholangiogram) to ascertain correct anatomy; and (10) understanding the concept of time-out. Surgeons should be facile with these aspects of this culture of safety in cholecystectomy in an attempt to reduce the incidence of biliary/vascular injury during LC.
Please note, the MCQs(Multiple choice questions) on this ppt are according to the specifications and syllabus of Specialty Certificate Examination (SCE) in Gastroenterology and the European Section and Board of Gastroenterology and Hepatology Examination (ESBGHE). However, they provide useful knowledge in the relevant subject area in general. Hence, it is recommended you to go through these videos and gather some information to gain success in future medical and surgical field examinations.
Probably Pediatric Surgery is the only surgical specialty which opens all four body cavities to treat their little patients. This is a pictorial glimpse of the wide spectrum of Pediatric Surgery.
This is very important topic for Laparoscopic surgeons,as bile injury is not uncommon,how to approach such biliary injuries is prime to know for evolving surgeons.This slide would also helpful for surgery residents.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

ARTIFICIAL INTELLIGENCE IN HEALTHCARE.pdfAnujkumaranit
Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
