This document provides an introduction to evidence-based medicine (EBM). It defines EBM as a systematic approach to clinical problem solving that integrates the best available research evidence, clinical expertise, and patient values and preferences. The key steps of EBM are outlined as asking a focused clinical question, acquiring the best evidence to answer that question, appraising the validity and importance of the evidence, and applying the evidence to individual patients. Levels of evidence are also discussed, with the highest levels being systematic reviews and randomized controlled trials. Overall, the document provides a high-level overview of the basic principles and process of evidence-based medicine.

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
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:

2. What is evidence-based medicine (EBM)?
"A systematic approach to clinical problem solving by the
integration of best research evidence with clinical expertise and
patient values”
(David Sackett, et al. Evidence-based Medicine. How to Practice and Teach EBM, 2000)
"The conscientious, explicit, and judicious use of current best
evidence in making decisions about the care of individual patients”
(Gordon Guyatt, et al. Users' Guides to the Medical Literature, 2002)

3. Is an approach to decision-making
in which the clinician uses the best
evidence available, in consultation
with the patient, to decide upon
the option which suits that patient
best.
6. The steps of practicing EBM
1. Ask a focused question.
2. Acquire the best evidence.
3. Appraise the evidence.
4. Apply the evidence in practice.
• Amalgamate the valid evidence with other relevant information
(values & preferences, clinical/health issues, & system issues).
5. Assess the effectiveness and efficacy of EBM process( clinical audit).
9. II) Finding the evidence
• Search terms should be referred back to the original PICO
question.
• The process of finding evidence therefore follow three key steps:
A. Identify terms to fit your PICO question.
B. Look for secondary sources.
C. Search for primary sources.
11. B) Look for secondary sources
• Guidelines: RCOG Green-top guidelines, NICE, UK National Library
for Health, SIGN, US National Guidelines Clearinghouse; Canadian
Medical Association and New Zealand Guidelines Group.
• Evidence-Based Summaries: Up to date, DynaMed, etc.
• Systematic Reviews: Cochrane Library and systematic review/meta-
analysis/ filters in PubMed.

15.
16. C ) Search for Primary Sources (Original Studies)
• Search using PubMed, Scopus, Web of science, Embase, etc.
• Use methodological filters to target the right type of study.
For instance, PubMed filters for:
• Therapy , diagnosis, prognosis and etiology.
• Article type ( reviews, RCTs, etc.)
• Publication date

20. The levels of evidence and their role in EBM
• A cornerstone of EBM is the hierarchical system of classifying
evidence.
• This hierarchy is known as the levels of evidence.
• Physicians are encouraged to find the highest level of evidence to
answer clinical questions.

24. Oxford Centre for Evidence-based Medicine – Levels of Evidence (March 2009)
25. III) Critically Appraise the Evidence
• Determine the appropriateness of some evidence for a particular
clinical situation.
• Three main aspects to be appraised: V - I - A
1. Validity: (closeness to the truth).
Internal validity: refers to the soundness of the research
methodology.
External validity: refers to generalizability of the results.
27. IV) Apply the evidence to a particular patient
• Compare the patient with those in the study from which evidence
has been generated (similar disease state, similar baseline
characteristics etc.).
• Consider the patient’s values, beliefs, concerns, affordability,
compliance and readiness for the intervention.
28. Benefits of adopting EBM
• Minimizes the error and optimizes the quality in patient care.
• Reduces the cost of treatment.
• Helps in advancement of knowledge and keeping pace with
scientific progress.
