1. Cirrhosis is the most common cause of ascites, accounting for 85% of cases. Other causes include malignancy, tuberculosis, cardiac disease, and nephrotic syndrome.
2. Analysis of ascitic fluid can help determine the cause of ascites. A serum ascites albumin gradient (SAAG) ≥1.1 g/dL suggests portal hypertension while a SAAG <1.1 g/dL suggests a non-cirrhotic cause like malignancy or tuberculosis.
3. Gross appearance, cell count, SAAG, and biochemical properties of ascitic fluid provide clues to diagnose conditions like chylous ascites, spontaneous bacterial peritonitis, or biliary perforation
Hemorrhoids are swollen veins in the lowest part of your rectum and anus. Sometimes, the walls of these blood vessels stretch so thin that the veins bulge and get irritated, especially when you poop. Hemorrhoids are also called piles.

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.

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

Transudation of fluid into the
peritoneal cavity
6. PATHOPHYSIOLOGY IN NON CIRRHOTIC ASCITES
• Peritoneal carcinomatosis appears to cause ascites through the production of
proteinaceous fluid by tumor cells lining the peritoneum. Extracellular fluid
enters the peritoneal cavity to re-establish oncotic balance.
• liver metastases - portal hypertension caused by stenosis or occlusion of
portal veins by tumor nodules or tumor emboli
• HCC- Underlying cirrhosis related portal hypertension, tumour induced portal
vein thrombosis or both
• Chylous ascites in patients with malignant lymphoma appears to be caused
by lymph node obstruction by tumor and rupture of chyle-containing
lymphatics.
• Tuberculosis-production of proteinaceous fluid, as in peritoneal
carcinomatosis.
• Biliary/Pancreatic ascites- leakage of pancreatic juice or bile into the
peritoneal cavity.
7. CLINICAL FEATURES FOR EVALUATION
• Ascites frequently develops during a patient’s first episode of decompensation of
alcoholic liver disease.
• Patients with a long history of stable cirrhosis and the sudden development of
ascites should be suspected of harbouring a hepatocellular carcinoma
• Malignancy-related ascites frequently is painful, whereas cirrhotic ascites usually
is not, unless bacterial peritonitis or alcoholic hepatitis is superimposed.
• SISTER MARY JOSEPH NODULE in umbilicus- Malignancy
• Tumors causing Malignant ascites --ovarian, colorectal, pancreatic and uterine;
extra-abdominal tumors originating from lymphoma, lung and breast*
• Cardiac Disease- Elevated JVP
• Collaterals in the back may indicate an obstruction of the inferior vena cava.
• Presence of enlarged lymph nodes may suggest tuberculosis or lymphoma.
*Sangisetty SL, Miner TJ. Malignant ascites: a review of prognostic factors,
pathophysiology and therapeutic measures. World J Gastrointest Surg. 2012 Apr
27;4(4):87.
8. CLASSIFICATION OF ASCITES
• GRADE 1- Mild ascites only detectable by ultrasound
• GRADE 2- Moderate ascites evident by moderate symmetrical distension of
abdomen
• GRADE 3- Large or gross ascites with marked abdominal distension
• The ascites that recurs at least on three occasions within a 12-month period
despite dietary sodium restriction and adequate diuretic dosage is defined as
recidivant*
*Arroyo V, Ginès P, Gerbes AL, Dudley FJ, Gentilini P, Laffi G, Reynolds TB,
Ring‐Larsen H, Schölmerich J. Definition and diagnostic criteria of refractory ascites
and hepatorenal syndrome in cirrhosis. Hepat. 1996 Jan;23(1):164-76.
9. Abdominal Paracentasis
• A diagnostic paracentesis should be performed in all patients with new onset grade 2 or
3 ascites, and in all patients hospitalized for worsening of ascites or any complication of
cirrhosis (Level A1).*
• Contraindications of Paracentasis: Coagulopathy should preclude paracentesis only when
there is clinically evident hyperfibrinolysis (three-dimensional ecchymosis/hematoma) or
clinically evident disseminated intravascular coagulation.**
• Other Contraindications:-
1. Pregnancy
2. Abdominal skin infection at the proposed puncture site
3. Severe Bowel distension
4. Uncooperative patient

10. ASCITIC FLUID ANALYSIS
GROSS APPEARANCE: This can range from water-clear to frankly purulent, bloody,
or chylous.
• The opacity of many cloudy ascitic fluid specimens is caused by neutrophils.
• Fluid with an absolute neutrophil count less than 1000/mm3 may be nearly clear.
Fluid with a count greater than 5000/mm3 is quite cloudy
• Ascitic fluid with a very low protein concentration may have no pigment and look
like water.
• An RBC count of 10,000/mm3 is the threshold for a pink appearance; lower
concentrations result in clear or turbid fluid. Ascitic fluid with an RBC count
greater than 20,000/mm3 is distinctly red. Blood stained fluid is usually due to
malignancy but may occur with tuberculosis, pancreatitis, hepatic vein
thrombosis, or due to a traumatic tap*
• Samples from patients with hepatocellular carcinoma are regularly bloody, but
only about 10% of samples from patients with peritoneal carcinomatosis are
red**

Clinical Medicine 2000; 5: 80. 2000;9.
• ** Runyon BA, Hoefs JC, Morgan TR. Ascitic fluid analysis in malignancy‐related
ascites. Hepatology. 1988 Sep 1;8(5):1104-9.
11. • Opaque milky fluid- Chylous ascites (TG >200 mg/dl)
• Cloudy ascites, also known as pseudochylous ascites, may indicate
peritonitis, pancreatitis or a perforated bowel*
• Deeply jaundiced patients have bile-stained ascitic fluid
• Dark-brown fluid with a bilirubin concentration greater than that of serum
usually indicates biliary perforation**
• Pancreatic ascites may be pigmented because of the effect of pancreatic
enzymes on RBCs. The degree of pigmentation ranges from tea-colored to
jet black, as in pancreatic necrosis.
• Black ascitic fluid also may be found in patients with malignant melanoma

of choleperitoneum. J Clin Gastroenterol 1987; 9:543-5
12.
13. TESTS
CELL COUNT:
• The WBC count in uncomplicated ascites in the setting of cirrhosis is usually
less than 500/mm3. The upper limit of normal for the absolute PMN count
in uncomplicated ascitic fluid in cirrhosis is usually stated to be lower than
250/mm3.
• SBP is the most common cause of an elevated ascetic Fluid WBC count
• An ascites-specific dipstick has been developed and calibrated to 100%
sensitivity in detecting a neutrophil count greater than or equal to 250
cells/mm*
• Leakage of blood into the peritoneal cavity leads to an elevated ascitic fluid
WBC count.To correct for this, 1 PMN is subtracted from the absolute
ascitic fluid PMN count for every 250 RBCs
*Mendler MH, Agarwal A, Trimzi M, et al. A new highly sensitive point of care
screen for spontaneous bacterial peritonitis using the leukocyte esterase
method. J Hepatol 2010; 53:477-83.
14. SERUM ASCITIS ALBUMIN GRADIENT
• Calculating the SAAG involves measuring the albumin concentration of
serum and ascitic fluid specimens obtained on the same day and
subtracting the ascitic fluid value from the serum value. If the SAAG is
greater than or equal to 1.1 g/dL (11g/L), the patient has portal
hypertension, with approximately 97% accuracy.*
• Conversely, if the SAAG is less than 1.1 g/dL (11 g/L), the patient is unlikely
to have portal hypertension
• If the first result is borderline (e.g., 1.0 or 1.1 g/dL )repeating the
paracentesis and analysis usually provides a definitive result
*Runyon BA, Montano AA, Akriviadis EA, Antillon MR, Irving MA,

17. FALSE LOW SAAG:
• SR. Albumin <1 gm/dl
• Hypotension
• Sr. Globulins >5 gm/dl
To correct the SAAG in the setting of a high serum globulin level, the
following formula is used*:-
Corrected SAAG= Uncorrected SAAG X 0.16 X (Sr. Globulin + 2.5)
FALSE HIGH SAAG
• Chylous ascites
*Hoefs J. Globulin correction of the albumin gradient Correlation with
measured serum to ascites colloid osmotic gradient. Hepatology 1992;
16:396-403.
18. ASCITIC FLUID TOTAL PROTEIN
Ascitic fluid total protein concentration <2.5 g/dl:-
• Uncomplicated Cirrhotic ascites*
• Nephrotic ascites
• HCC
• Massive Liver Metastasis
*(Almost 20% of ascitic fluid samples in patients with cirrhosis will have a protein
concentration greater than 2.5 g/dL)
Ascitic fluid total protein concentration >2.5 g/dL:-
• Cardiac Ascites
(In patients with cardiac ascites, the SAAG may narrow with diuresis; such narrowing
does not happen in patients with cirrhosis.)
A total protein concentration <1.5 g/dl is generally considered a risk factor for SBP
19. Ascitic fluid Culture
• The most common bacterial infection of ascitic fluid, SBP, is monomicrobial, with
a low bacterial concentration (median colony count of only 1 organism/mL).*
• Multiple prospective trials have shown that bacterial growth occurs in only about
50% of instances when ascitic fluid with a polymorphonuclear leukocyte (PMN)
count greater than or equal to 250 cells/mm3 is cultured by older methods, i.e.
sending a syringe or tube of fluid to the laboratory, as compared to approximately
80% if the fluid is inoculated into blood culture bottles at the bedside and prior to
administration of antibiotics**
• A single dose of an effective antibiotic usually leads to a negative bacterial
culture.
*Runyon BA, Canawati HN, Akriviadis EA. Optimization of ascitic fluid culture
technique. Gastroenterology 1988; 95:1351-5
**Runyon BA, Antillon MR, Akriviadis EA, McHutchison JG. Bedside inoculation of
blood culture bottles is superior to delayed inoculation in the detection of
spontaneous bacterial peritonitis. J Clin Microbiol 1990;28:2811-2812.
20. ASCITIC FLUID GLUCOSE:
• Ascitic fluid glucose can drop significantly in severe infections like secondary peritonitis
or late stage of SBP. Low glucose can also be found in malignant ascites.
• In early SBP, the ascitic fluid glucose concentration is similar to that of sterile fluid.
ASCITIC FLUID pH:
• Can be used for the diagnosis of SBP
• In a study*,the mean (±S.E.) ascitic fluid pH in the SBP group was 7.25 ± 0.06 with a range
of 7.12 to 7.31, while the ascitic fluid pH in the group with sterile ascites was 7.47 ± 0.07
with a range of 7.39 to 7.58. The pH of the blood in both groups was 7.47 ± 0.03.
• The ascitic fluid pH is recommended as an easy, quick, sensitive, and specific means of
diagnosing SBP*
*Gitlin N, Stauffer JL, Silvestri RC. The pH of ascitic fluid in the diagnosis of spontaneous
bacterial peritonitis in alcoholic cirrhosis. Hepatology. 1982 Jul;2(4):408S-11S.
21. Ascitic Fluid LDH:
Elevated in:-
• Secondary peritonitis
• Malignant Ascites*
Ascitic Fluid Amylase:-
• In patients with acute pancreatitis or intestinal perforation (with release of
luminal amylase into the ascitic fluid), the fluid amylase concentration is
elevated markedly, usually greater than 2000 U/L, and approximately 5-fold
greater than simultaneous serum values
* Sevinc A, Sari R, Fadillioglu E. The utility of lactate dehydrogenase
isoenzyme pattern in the diagnostic evaluation of malignant and
nonmalignant ascites. J Nat Med Asso. 2005 Jan;97(1):79.
22. Ascitic fluid Bilirubin:-
An ascitic fluid bilirubin level greater than 6 mg/dL and greater than the
serum level of bilirubin suggests biliary or proximal small intestinal
perforation into ascitic fluid
Ascitic Fluid Triglyceride:
• Chylous ascites has a TG concentration greater than 200 mg/dL (2.26
mmol/L) and greater than the serum level.
• Abdominal malignancy and cirrhosis are the commonest causes in
developed countries and account for over two-thirds of all cases, whereas
chronic infections like tuberculosis and filariasis account for the majority of
the cases in developing countries*
*Al-Busafi SA, Ghali P, Deschênes M, Wong P. Chylous ascites: evaluation and
management. ISRN hepatology. 2014 Feb 3;2014.
23. Peritoneal Tuberculosis
Ascitic fluid for AFB and Mycobacterial culture:
• Examination of an Acid fast stained smear of ascitic fluid has a
disappointingly low yield. Direct smear for Ziehl-Neelson stain has a
reported sensitivity of 0 to 6 percent*
• The sensitivity of ascitic fluid mycobacterial culture (20–50%) is low**, and
because of the delay in obtaining the results of mycobacterial cultures of
ascitic fluid, the mortality is high***, and the value of these tests in the
differential diagnosis of ascites is limited.

• FDA approved Enzyme Linked Immunospot Assay (ELISPOT) measuring gamma
producing T-cell responses to early secreted antigenic targets of mycobacterium
tuberculosis
• Sharma et al* evaluated the diagnostic accuracy and cost-effectiveness of ascitic
fluid interferon-gamma (IFN - gamma) and Adenosine deaminase (ADA) assays in
the diagnosis of tuberculous ascites. (IFN - gamma and ADA assays showed equal
sensitivity (0.97) and differed marginally in specificity (0.97 vs. 0.94). Difference in
AUCs was not significant (0.99 vs. 0.98, p<0.62)
• For differentiating TB from non-TB ascites, optimal cut off points were 112 pg/mL
for IFN-gamma and 37 IU/L for ADA.

26. Real time PCR bacterial DNA for
M.Tuberculosis
• PCR can be performed when tuberculous ascites is suspected.
• This method has a high sensitivity (94%)*
• PCR offers a timesaving method in contrast to current Mycobacterium
culture techniques.

27. Ascitic Fluid cytology:
• The ascitic fluid cytology is positive only in the setting of peritoneal
carcinomatosis. The sensitivity of cytology in detecting peritoneal
carcinomatosis is 96.7% if 3 samples (from different paracentesis
procedures) are sent and processed promptly; the first sample is positive in
82.8% and at least 1 of 2 samples is positive in 93.3%.*
• Crucial factors are avoiding any time delay between obtaining the ascitic
fluid and cytology processing as well as obtaining at least 50 ml ascitic fluid,
or even 1000 ml if the first test was negative.**
• The sensitivity of cytology in patients with hepatocellular carcinoma and
ascites is low (~27%)***

28. Ascitic Fluid Cholesterol and SACG
• Ascitic fluid cholesterol and Mean SACG are highly sensitive, specific and are
having high Diagnostic accuracy of 90% and 93% with a a cut off level of
70mg% and 54 mg% respectively. Hence being simple and cost effective,
these can be widely utilized to separate malignant ascitis from nonmalignant
causes*

29. Others
Ascitic Fluid CA-125
• Essentially all patients including men with ascites or pleural fluid of any cause have an
elevated serum CA-125; when ascites is controlled, the CA-125 level decreases
dramatically. This test is elevated when mesothelial cells are under pressure from the
presence of fluid; it is very nonspecific.
• Patients with ascites should not have serum tested for CA-125.
Leucocyte esterase reagent strips :
• Leukocyte esterase reagent strips are widely used for urinary analysis with the
advantages of a simple, inexpensive and rapid bedside test.
• Several studies have examined the usefulness of this method for diagnosing SBP and
found this test had a sensitivity and specificity ranging from 80-93% and 93-98%,
respectively. The negative predictive value is remarkably high ranging from 97-99%,
which makes it an ideal tool to rule out SBP*
