Toxicology is a very important topic and if u try reading each
poisons Separately , u will definitely forget them.
So best way to remember them more is to practice
MCQs and then read topics by correlating.
That’s what I think….
It may or may not apply for u…..
But atleast try once like this and then choose your own way .

Toxicology
Volatile poisons
Ethyl alcohol (Ethanol)
It is colorless liquid with characteristic odor.
It is obtained from fermentation of food e.g. barley , bread or fruits.
The percentage of alcohol in beverages caries according to the type of alcoholic beverages.
Its most common ingested toxin throughout world,
Thousands of deaths occur due to overdose , suicide and accidental intake of alcohol.
Alcoholic beverage
The alcoholic content of different beverages are:
Beer:2-8%
Ligh wine:5-10%
Heavy wines:10-20%
Brany ,Rhum (rum),vodka and wisky:40-50% .
Absorption and elimination
Ethyl alcohol can be absorbed by the mucus membrane of the stomach and the upper part of the small intestine.
Absorption occurs more rapidly when its taken on an empty stomach. its delayed by the presence of food, especially fatty food.
After absorption : it reaches its maximal concentration in the blood after 0.5-1 hr.
About 90% of the amount absorbed is oxidized in the body into acetaldehyde and then into carbon dioxide + water +energy. the remaining 10% is excreted unchanged in the urine and breath.
The rate of oxidation of alcohol in the body after absorption is 0.1ml/hg/bodywt/hour.
The concentration of alcohol in the blood can be indirectly estimated by measuring its cocentration in alveolar air by aclometer.
Metabolism
Ethanol is oxidized to acetaldehyde by alcohol dehydrogenase and then metabolized into Co2 and water, this is considered the main path of metabolism , microsomal ethanol oxidizing system (MEOS) plays a minor rule.
Because of mucosal and hepatic metabolism , the oral dose yields a lower blood ethanol level than in equivalent
Administered I.V dose.
METHYL ALCOHOL (Methanol)
Methyl alcohol is widely used in industry and laboratories and hospitals as a solvent. Many cases of poisoning occurs due to adulteration of ethyl alcohol by adding methyl alcohol, or methyl alcohol is taken as a substitute for ethyl alcohol .
Metabolism
Methyl ALCOHOL is metabolized mainly in the liver by dehydrogenases to formaldehyde and formic acid, both are more toxic than methanol leading to blindness and acidosis .
Fatal Dose :
60-150 mls 15 mls is enough to cause visual effect.
Action:
retinal edema , optic atrophy , CNS depression, cyanosis, metabolic acidosis , neuritis optic and blindness
Fatal Period : variable
Fomepizole

Exercise Testing in Cardiology : Dr. Akif Baigakifab93
The testing modality and protocol should be selected in accordance with the patient’s estimated functional capacity based on age, estimated physical fitness from the patient’s history, and underlying disease
Several exercise test protocols are available for both treadmill and stationary cycle ergometers
Patients who have low estimated fitness levels or are deemed to be at higher risk because of underlying disease (e.g., recent MI, heart failure) should be tested with a less aggressive exercise protocol
Treadmill and cycle ergometers may use stepped or continuous ramp protocols
Work rate increments (stages) during stepped protocols can vary from 1 to 2.5 METs
Ramp protocols are designed with stages that are no longer than 1 minute and for the patient to attain peak effort within 8 to 12 minutes
The natriuretic peptide system works antagonistically to the RAAS and has favorable effects on the pathogenesis of heart failure
Natriuretic peptides are broken down by an enzyme called neprilysin
Neprilysin is also responsible for the breakdown of other substances, including bradykinin and angiotensin II
Sacubitril/valsartan is a combination product
Sacubitril is a pro-drug that, upon activation, acts as a neprilysin inhibitor
It works by blocking the action of neprilysin, thus preventing the breakdown of natriuretic peptides
This leads to a prolonged duration of the favorable effects of these peptides
Coronary heart disease (CHD) remains a leading cause of death worldwide, accounting for 16% of total deaths globally .
Atherosclerosis plays a central role, with early fatty streaks progressing to late complex atheromas
Vascular calcification, the pathogenic and process of ectopic bone production, specifically was shown to strongly correlate with degree of atherosclerosis (both calcified and noncalcified)
Vascular calcification was shown independently to predict cardiovascular morbidity and mortality
These associations, combined with the radio-opaque appearance of calcium hydroxyappatite on CT images, have led to extensive investigation of the quantification, or scoring, of coronary artery calcium (CAC).
CAC scoring has emerged as a widely available and powerful tool for stratifying cardiovascular risk, predicting patient outcomes, and guiding preventive therapy
A coronary bifurcation consists of a flow divider (carina) and three vessel segments:
The proximal main vessel (PMV)
The distal main vessel (DMV) and
The side branch (SB).
A bifurcation lesion is a major epicardial coronary artery stenosis next to and/or including the ostium of a significant side branch
A significant SB is a branch whose severe narrowing or acute occlusion before or during intervention can cause considerable ischemia or a new infarction area that will worsen the clinical course of a particular patient.
Other important elements to consider that are not inherent in the bifurcation classifications include:
Extent of disease on the SB (limited to the ostium or involving the vessel beyond the ostium)
Its size (over 2.5mm in reference diameter)
Bifurcation angle, and
Disease distribution
Left ventricular (LV) dysfunction remains one of the
best prognostic determinants of survival in patients
with coronary artery disease (CAD)
⚫ It was originally thought that dysfunctional
myocardium after an infarction was irreversibly
damaged
⚫ However, it was later recognized that some of the
involved tissue remained viable and contractility may
be restored with revascularization

Tetralogy of Fallot (TOF) is a congenital heart defect, which has four anatomical components:
Anterior malalignment ventricular septal defect (VSD)
Aortic override over the muscular septum
Variable degrees of subvalvar, valvar, and supravalvar pulmonary stenosis
Right ventricular (RV) infundibular narrowing and RV hypertrophy
Ventricular septal defects occur either as an isolated defect or as a component of a more complex lesion
It occurs in 50 percent of all children with CHD and in 20 to 30 percent as an isolated lesion
Most common congenital cardiac anomaly in children
Second most common congenital abnormality in adults, second only to bicuspid aortic valves
They are more common in premature infants and those born with low weight
VSDs are slightly more common in females (56%)
Patients with peripheral artery disease who have undergone lower-extremity revascularization are at high risk for major adverse limb and cardiovascular events
The efficacy and safety of rivaroxaban in this context are uncertain
Most common cyanotic heart defect seen in children beyond infancy, accounting for a third of all congenital heart disease (CHD) in this age group
Tetralogy of Fallot (TOF) is a congenital heart defect, which has four anatomical components:

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!

-Resembles tetanus
-Animal poison
-Arrow poison
- Increases Libido = Aphrodisiac property
21. -Pleurosthotonus/Ophistotonus/ Emprosthotonus
-Risus sardonicus
-Postmortem caloricity : Strychnine increases body temperature after death
-Post-synaptic block
-Rigor mortis : Appears early and stays for long time
Note: Anything which leads to fatigue of muscles leads to early rigor and
since strychnine increases muscle contraction leads to early fatigue.
-Antidote : Diazepam

alkalinisation is done for
treatment
22.
23. - Botulism is a rare and potentially fatal illness caused by a toxin, produced by the
bacterium Clostridium botulinum.
- Botulinum inhibits the release within the nervous system of acetylcholine,
a neurotransmitter, responsible for communication between motor
neurons and muscle cells.
- All forms of botulism lead to paralysis that typically starts with the muscles
of the face and then spreads towards the limbs.
- In severe forms, botulism leads to paralysis of the breathing muscles and
causes respiratory failure.
- Honey can contain the organism, and for this reason, honey should not be fed to
children under 12 months.
-Treatment is with an antitoxin.
-In those who lose their ability to breathe on their own, mechanical ventilation may be
necessary for months.
