The respiratory system has several functions including inhaling oxygen and exhaling carbon dioxide. It is comprised of organs like the nasal cavity, pharynx, larynx, trachea, bronchial tubes, and lungs. The nasal cavity warms and humidifies air before it reaches the lungs. The pharynx is shared by the respiratory and digestive systems. The larynx contains the vocal cords which produce sound. The trachea transports air to the bronchi and lungs. In the lungs, bronchioles divide into alveoli where gas exchange occurs across the respiratory membrane.
In humans, the respiratory tract is the part of the anatomy of the respiratory system involved with the process of respiration. Air is breathed in through the nose or the mouth. In the nasal cavity, a layer of mucous membrane acts as a filter and traps pollutants and other harmful substances found in the air.
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

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!

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

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

volume (ERV) after a normal exhale
Residual volume (RV) Volume of air remaining in lungs after a
forced exhale
55. Respiratory Muscles - Inhalation
Diaphragm
Muscle separates abdomen from thoracic cavity
Contracts and moves down into abdominal cavity
Causes decrease of pressure, negative pressure, within
chest cavity
Air then enters lungs (inhalation) to equalize pressure
56. Respiratory Muscles - Inhalation
Intercostal muscles
Located between ribs
Raise rib cage to further enlarge thoracic cavity
Increases negative pressure
Assists with forceful inhalation
58. Respiratory Muscles - Exhalation
Unforced exhale results when:
Diaphragm and intercostal muscles relax
Thoracic cavity becomes smaller
Creates positive thoracic pressure
Air flows out of lungs to equalize pressure
For forceful exhale
Use additional chest and neck muscles to further decrease
size of thoracic cavity
Create greater positive pressure
59. Respiratory Rate
One of the vital signs (VS), along with heart rate,
temperature, and blood pressure
Respiratory rate dependent on level of CO2 in blood
When CO2 level is high, we breathe more rapidly to
expel excess
If CO2 levels drop, respiratory rate will also drop until
CO2 builds up in bloodstream

pleurisy characterized by sharp pain
with each breath
collection of air in pleural
pneumothorax cavity; may result in collapsed
lung
97. Clinical Laboratory Tests
arterial blood blood test of oxygen and carbon dioxide levels in
gases (ABGs) the blood

sensitivity (C&S) then determines best antibiotic to use
sputum cytology examining sputum for malignant cells
98. Diagnostic Imaging
X-ray of lung after inhaling radiopaque
bronchography
substance
chest X-ray X-ray of the organs of the thoracic cavity
pulmonary X-ray of lungs after injecting dye into blood
angiography vessel

ventilation-
for ventilation portion; radioactive dye is injected
perfusion scan
for perfusion portion; looks for pulmonary emboli
99. Endoscopic Procedures
bronchoscopy visual examination of bronchial tubes using a
(Bronch) bronchoscope
laryngoscopy visual examination of larynx using a laryngoscope
101. Pulmonary Function Tests
measures oxygen level in
oximetry blood; uses oximeter on
patient’s finger tip
pulmonary group of tests to measure air
function test flow in and out of lungs, lung
(PFT) volumes, and gas exchange
measures lung capacity using
spirometry
a spirometer

polysomnography sleeping to identify sleep
apnea
test for cystic fibrosis;
this disease causes
sweat test
large amount of salt in
sweat
introducing purified
protein derivative (PPD)
tuberculin skin
under the skin;
tests (TB test)
determines if person has
been exposed to TB
105. Respiratory Therapy
medication suspended in a
aerosol mist and inhaled; delivered by
therapy a nebulizer or metered dose
inhaler (single puff dose)
placing a tube through the
endotracheal
mouth and into the trachea to
intubation
keep airway open
intermittent
method for assisting patients in
positive
breathing with a machine that
pressure
produces an increase in
breathing
positive thoracic pressure
(IPPB)
110. Respiratory Therapy
drainage of bronchial secretions
by placing patient in positions
postural
using gravity to promote
drainage
drainage; cystic fibrosis
treatment
supplement providing additional oxygen
oxygen concentration to improve oxygen
therapy levels in bloodstream
machine that provides artificial
ventilator ventilation for a patient unable to
breathe alone

112. Surgical Procedures
surgical puncture of chest
thoracentesis wall to remove fluids; also
called thoracocentesis
insertion of tube (a chest
thoracostomy tube) into chest to drain off
fluid or air
emergency procedure to
create an opening directly
tracheostomy into trachea so person can
breathe easier; also called
tracheotomy
115. Additional Procedures
cardiopulmonary emergency treatment given to persons
resuscitation (CPR) when respiration and heart stop
technique for removing foreign body
Heimlich maneuver
obstructing trachea or pharynx
