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

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!

4. A flap is a segment of tissue that contains a network of
blood vessels that may be transferred from a donor site to
reconstruct a secondary defect.
1440 : Dutch word "flappe" : something that hung broad and
loose, fastened only by one side.
Whether or not we use our best flap choice in the first instance,
we must always be ready for its failure and have a backup flap
in mind which will “dig us out of a hole”.
Introduction
5. Based on Blood supply
Random Axial
Random-pattern flaps: Have no dominant blood supply.
Axial flaps: Have a dominant feeding vessel.
Reverse-flow flaps (also known as distal pedicle flaps
or reverse axial pattern flaps): The proximal blood
supply is divided, leaving the flap to survive on the
intact distally based vessels.
Peninsular flap / Island flap.
CLASSIFICATION
6. CLASSIFICATION
According to the proximity to the defect
Local: The flap shares a side with the defect (e.g.,
rhomboid flap).
Regional: The flap is near, but not immediately
adjacent to the defect (e.g., paramedian forehead flap).
Distant: The flap is not near the defect (e.g., PMMC
flap).
Free flap: Free tissue transfer.
7. Local flaps
Flaps adjacent to the defect requiring
reconstruction – Local flaps.
8. Distant flaps
Flaps which are further away and
not contiguous with the defect –
Distant flaps.
Distant flaps that remain attached
to the body – Pedicled flaps. The
base of the flap that contains the
blood supply is called the pedicle.
Distant flaps those detached and
revascularised by anastomising
arteries and veins – Free flaps.
9. CLASSIFICATION
By method of tranfer from the donor site
1) Advancement flaps
2) Rotation flaps
3) Transposition flaps : Rhombic and Bilobed flaps.

51. BUCCAL FAT PAD
Heister (1727) - “Glandula molaris.”
Bichat (1801) - True nature of the BFP. ‘‘boule de
Bichat,’’ sucking pad, sucking cushion, masticatory fat
pad, or buccal pad of fat.
Scammon - Anatomy of the BFP .
Egyedi (1977) – BFP as a versatile pedicled graft.
Neder described the use of buccal pad fat as free
graft to close oral defects.
Tideman et al. (1986) described its detailed anatomy,
vascular supply and operative technique.
Yenwas the first to succeed in covering the buccal
defect with a split thickness skin graft in treating a case
of OSMF.
52. The possible functions of the BFP
Sucking in newborns
Separating the masticator muscles from one another
and from the adjacent bony structures,
Enhancement of intermuscular motion, (syssacosis)
Protection of neurovascular bundles.
Advantages of BFP as a pedicled graft are
Easy harvest
Low morbidity
High success rate
Elimination of donor-site skin scars.
53. ANATOMY
The buccal fat pad located anterior
to the masseter muscle and deep to
the buccinator muscle.
Acc to Traditional anatomic
descriptions Buccal fat pad has a
central body and 4 processes:
buccal, pterygoid,pterygopalatine,
superficial, and deep temporal.
Recently, Buccal fat pad was
described as having 3 lobes
anterior, intermediate, posterior.
The 4 processes described are
from the posterior lobe
Atlas Oral Maxillofacial Surg
Clin N Am 15 (2007) 23–32
54. ANATOMY
•The main body lies on the anterior border of the masseter
muscle and extends deeply to lie on the posterior maxilla and
forward along the buccal vestibule.
•Buccal process - located deep to the superficial
musculoaponeurotic system at the anterior border of the
masseter and partially responsible for cheek contour.
•Pterygopalatine process - extends into the pterygopalatine
fossa encapsulating the pterygopalatine vessels.
55. ANATOMY
•Pterygoid extension - posteriorly extends in to
pterygomandibular space.
•Temporal extension can be divided further into 2 parts:
•Superficial part - between the deep temporal fascia,
temporalis muscle, and tendon.
•Deep part - behind the lateral orbital wall and frontal process
of the zygoma and into the infratemporal space.
•Blood supply
•Buccal and deep temporal branches of the maxillary artery,
Transverse facial branch of the superficial temporal artery,
Branches of the facial artery such as the inferior buccinator
artery.
56. LIGAMENTS ATTACHED FROM ATTACHED TO
Maxillary ligament
(fibrous condensation)
Anterior lobe Maxilla
Posterior zygomatic
ligament
Intermediate lobe Zygomatic process
Medial and lateral
infraorbital ligaments
Intermediate lobe
(Medial and lateral
side)
Infraorbital rim
Temporalis tendon
ligament
Posterior lobe Temporalis tendon
posteriorly.
Buccinator ligament Anterior lobe Buccinator
membrane.
Each process has its own capsule and is anchored to
the surrounding structures by ligaments.
57. The buccal and zygomatic
branches of the facial nerve
and the parotid duct lie lateral
to the fat pad and should not
be injured during flap
mobilization.
The parotid duct courses with
the buccal branches of the
facial nerve anteriorly
(superficial), and on the lateral
surface of the BFP, it
penetrates the buccinator
muscles, entering the oral
cavity.
58. •The buccal extension and main body together constitute 55%-
70% of total weight.
•BFP seems to be constant throughout life, usually with no direct
relationship to the total body fat present.
•The mean volume in males was 10.2 ml (7.8–11.2 ml), and in
females it was 8.9 ml (7.2–10.8 ml).The mean thickness was 6
mm, and mean weight of 9.7 g.
•Blunt surgical dissection reveals that the fat pad may be
estimated between 7 to 9.34 cm with reproducible vascularity as
long as the flap is tension-free.
59. SURGICAL PROCEDURE
The BFP was approached via the posterior- superior margin of the
created buccal defect or by placing 2 cm horizontal vestibular
incision extending backwards from above the maxillary second
molar tooth, and then dissected with an index finger.
Blunt dissection through the buccinator and loose surrounding
fascia, allowed the buccal fat pad to herniate into the mouth.
The body and the buccal extension of BFP were gently mobilised by
blunt dissection, taking care not to disrupt the delicate capsule.
After the pad had been dissected free from the surrounding tissues,
it was grasped with vascular forceps, gently teased out, advanced,
and expanded over the defect.
The BFP was teased out gently until a sufficient amount was
obtained to cover the defect without tension .
60. HEALING OF THE BFP
Clinically, in the typical course, the surface of the
orally exposed fat becomes yellowish-white in 3 days
and then gradually becomes red within 1 week,
which is most likely due to the formation of young
granulation tissue. This changes into firmer
granulation tissue during the 2nd week, and becomes
completely epithelialized with a slight contraction of
the wound by 3 weeks after the operation.
The BFP healed in 2 weeks and completely epithelized
in 6 weeks.5
