Today,I've done a presentation for students about most important health issue in our community,that is called Middle East Respiratory Syndrome-Coronavirus(MERS-CoV).
Its a small presentation about corona virus. Hope you will get an idea about it. Its not detail its just to give an overview of the virus and its mode of transmission. Preventive measures are also discussed.
Coronaviruses & COVID 19 - Its Morphology, Role, Mechanism of Action, and Tre...Haider Ali Malik
Coronaviruses (CoV) are a large family of viruses transmitting between animals and people that cause illness ranging from the common cold to more severe diseases such as Middle East respiratory syndrome (MERS-CoV) and severe acute respiratory syndrome (SARS-CoV).
COVID-19 is a respiratory illness caused by a newly identified coronavirus, SARS-CoV-2
The current COVID-19 outbreak originated in Wuhan, China, in late 2019. World Health Organization (WHO) has been to characterized the outbreak as a pandemic on 11 March 2020. (WHO Bulletin 2020)

Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
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:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

ABDOMINAL TRAUMA in pediatrics part one.drhasanrajab
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.
1. Middle East Respiratory Syndrome Coronavirus
(MERS-CoV)-Important Public Health Threat
LEYLA RASHIDLI
Jeddah International Turkish School, Grade 11/D(FLDC/YD)
2. INTRODUCTION
• Communicable diseases are leading cause of morbidity
and mortality around the world
• Whenever a new virus associated with an acute
respiratory illness emerges, medical authorities around
the world are put on high alert and vigilance
• The Middle East Respiratory Syndrome Coronavirus
(MERS-CoV) is a new coronavirus that has not been seen
in humans before and has occurred only in residents of
or travellers to certain Middle East countries.
3. How it started?
• In September 2012, a novel coronavirus (later called
MERS-CoV) was isolated from a patient in Saudi Arabia
who had died of an acute respiratory illness and renal
failure.
• Since September 2012, 180 confirmed infections with
Middle East respiratory syndrome coronavirus (MERSCoV) have been reported to the World Health
Organization, including 77 deaths.
• MERS-CoV is a new infection and there are many gaps in
our knowledge that will inevitably take time to fill in.
4. What is the source of MERS-CoV?
• It is not known for certain where the virus came
from, however, it likely came from an animal
source.
• In addition to humans, MERS-CoV has been found
in camels in Qatar and a bat in Saudi Arabia.
• However, we don’t know whether camels are the
source of the virus.
• More information is needed to identify the possible
role that camels, bats, and other animals may play
in the transmission of MERS-CoV.
6. Transmission
• MERS-CoV does not spread
easily from person to person.
• In the cases where it has
appeared to have spread
between people, those cases
involved close contacts:
family members, co-workers,
fellow patients and
healthcare workers.
7. What is the current situation?
• 180 confirmed infections with MERS-CoV have
been reported to the World Health
Organization, including 77 deaths.
• All the cases have been linked to six countries
in or near the Arabian Peninsula.
• This virus has spread from ill people to others
through close contact.
8.
9. Survival of Coronaviruses
Coronaviruses are fairly fragile, surviving
outside the body for only about 24 hours;
They are easily destroyed by detergents and
cleaning agents;
Cleaning environmental surfaces with water
and detergent and applying commonly used
disinfectants (such as hypochlorite) is an
effective and sufficient procedure.

cases of novel coronavirus (nCoV) infection. Interim guidance - 6 May 2013
10. WHAT ARE THE SIGNS AND SYMPTOMS?
http://www.moh.gov.sa/en/CoronaNew/PublicationsAwareness/Pages/003.aspx
15. TAKE HOME MESSAGE
• There is no a sustained spread of infection in
communities , however, the situation is still evolving.
• Experts do not have enough information on
the virus to make specific treatment
recommendations or to develop vaccine
• Don’t panic! Get informed. Be prepared.
• Compliance with mentioned preventive measures
is only protective approach of population to
avoid MERS-CoV
