This document discusses various tests used to evaluate gastrointestinal and liver function. It begins by outlining objectives to discuss gastric, liver, and pancreatic function tests. For gastric function, tests are described to detect hyperchlorhydria or achlorhydria including fractional meal tests, histamine tests, pentagastrin tests, and endoscopy. Liver function tests evaluate secretion, metabolism, synthesis, detoxification and cellular integrity using measures like bilirubin, enzymes, proteins, imaging and biopsy. Pancreatic function is assessed through analysis of pancreatic juice and products of digestion as well as serum amylase.
Test for pancreatic and intestinal functions are very important for clinical evaluation gastro intestinal disorders . So it will e useful for medical and allied professional students and practitioners.

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.
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

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
3. Gastric Function Tests
Used to establish the presence of
hyperchlorhydria (associated with peptic
ulcer) or
achlorhydria (complete absence of acid
secretion) associated with pernicious
anaemia.
Thursday, May 6, 2021
4. It includes…
Fractional test meal test.
Histamine test
Augmented histamine test.
Pentagastrin test
Insulin test
Barium meal study
Endoscopic examination and biopsy
Thursday, May 6, 2021
5. Fractional test meal test.
Previously used commonly for analysis of
gastric juice.
Presently, it is no more used because of its
relative insensitivity and inconvenience.
Thursday, May 6, 2021
6. Fractional test meal test.
After an overnight fast,
the gastric fluid present
in the stomach is
aspirated with the help of
the Ryles’ tube
Test meal -300 mL of
oat meal gruel or dry
toast and cup of tea or
wheat biscuits and 300
mL of water.
After 15 min, a sample
of gastric content (10
mL of fluid) is
aspirated.
The procedure is
repeated every 15 min
for 3 h.
A total of 13 samples
are collected in
separate
containers.
Analyzed for free acidity,
combined acidity (Fig.
7.3-19), starch and sugar,
bile, total chlorides,
blood lactic acid and
mucus.
Thursday, May 6, 2021
7. Histamine test
More sensitive,
First, the histamine is a powerful stimulator of
acid secretion and
Secondly, due to histamine injection, acid level
increases very rapidly
So there is no time for neutralization of acid
Thursday, May 6, 2021
8. Histamine test
Thursday, May 6, 2021
After
overnight fast,
in the
morning
stomach is
aspirated and
washed with
distilled water.
0.5 mg
histamine
is injected
subcutaneo
usly
The gastric
samples
are
aspirated
and
analysed
9. Augmented histamine test.
Performed with progressively increasing
dose of histamine in a stepwise manner
till a maximal secretory response is
obtained.
The maximal secretory response
correlates well with the total
number of the parietal cells in the
gastric mucosa.
Thursday, May 6, 2021
10. Pentagastrin test
Performed
to assess
the gastric
acid
status.
It is
performed
similar to the
histamine
test.
Except that in
this, instead of
histamine, 6 mg
of pentagastrin
(a synthetic
gastrin) is given
as subcutaneous
injection.
Thursday, May 6, 2021
11. Insulin test
Principle - Hypoglycaemia (blood sugar
below 45 mg%) produces vagal stimulation
through hypothalamus and that vagal
stimulation causes secretion of acid from the
stomach.
Thursday, May 6, 2021
12. Test
Seven units of insulin are given
intravenously and the gastric samples are
tested for the presence of free acid, as done
in histamine test.
Thursday, May 6, 2021
13. Interpretation.
Acid secretion occurs after insulin injection
(positive test) only if vagus is intact.
Therefore, insulin test performed after
vagotomy operation (for gastric ulcer)
To know whether all the fibres of nerve
supplying stomach are cut or not.
If vagotomy is done properly, insulin test is
negative
Thursday, May 6, 2021
14. Barium meal study
Radiographic evaluation of the status of
mucosa and lumen of the upper intestinal
tract.
Patient swallows a suspension of radiopaque
barium sulphate, while its passage through
the GIT is observed by radiograph on
fluorescent screen and films are taken to
provide a permanent record.
Thursday, May 6, 2021
16. Endoscopic examination and
biopsy
Esophagus, gastric and duodenal mucosa can be
directly visualized by the endoscope.
The endoscopes carry a channel through which
biopsy forceps or a brush can be introduced to
obtain specimen for histological and cytological
examination.
Thursday, May 6, 2021
