Follow us on: Pinterest
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
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!

Neonatal seziure
1. By
Dr. Asmaa Abd El wakeel I brahim
Lecturer of Pediatrics/Neonatology
Al-Azhar Faculty of Medicine for Girls
2. Neonatal seizures
Seizure: abnormal electrical brain activity causing
neurological dysfunction.
Incidence
Seizures affect around 0.1% of all term infants and up
to 10% of very low birth weight (VLBW) infants—
newborns have a predominance of excitatory synapses
relative to adults and alongside other molecular factors
are more prone to seizures.
5. Clues to etiology
HIE is the most common cause of seizures in term
babies and characteristically presents in the first 24
hours with a history of fetal distress, need for
resuscitation at birth, and decreased conscious
level.
Group B streptococci and E. coli are the commonest
infective causes, andpresent from the end of the
first week onwards, as does Herpes simplex.
Intrauterine toxoplasmosis and cytomegalovirus
(CMV) infection present in the first 3 days.
6. Clues to etiology
Cerebral infarction (stroke) often presents with focal
seizures at 24– 72hours of age in an otherwise well
infant.
IUGR and preterm infants are at risk of
hypoglycaemia.
Poor feeding and weight loss may lead to
hypernatraemic dehydration.
Severe unconjugated jaundice and kernicterus—
decreased consciouslevel, abnormal neurology, and
typically opisthotonic posture.
7. • Clues to etiology
Preterm infants may have subtle seizures following
intraventricular haemorrhage (IVH) in the first 72
hours, with decreased Hb.
Neonatal abstinence syndrome— history of
maternal substance abuse, presents in first week
with other signs of withdrawal.
Inborn errors of metabolism: at least 1% of cases
of seizures in the newborn. caused by an enzyme
defect in the metabolic pathways of carbohydrates,
proteins, or fat, many cause disease due to
accumulation of toxic products unable to proceed
along the appropriate metabolic pathways.
8. • Clues to etiology
Inborn errors of metabolism:.
In these disorders, infants initially appear well, due
to the benefits of placental clearance of toxins until
birth, and only become encephalopathic and have
seizures after 2 to 3 days.
Biochemical markers for these disorders include
hypoglycemia, metabolic acidosis,
hyperammonemia, as well as specific patterns of
alteration in amino acid or organic acid profiles.
9. • Clues to etiology
Inborn errors of metabolism:.
Among metabolic disorders,Hyperglycinaemia—
increased fetal movements, intractable seizures,
commonly causes myoclonic events,
encephalopathy with depressed sensorium,
respiratory compromise, and hypotonia, burst
suppression on EEG, raised plasma and
cerebrospinal fluid (CSF) glycine levels.
10. Clues to etiology
Pyridoxine deficiency— intractable seizures with
dramatic resolution following pyridoxine
administration
which results in deficiency of alpha amino-adipic
semialdehyde (α-AASA) dehydrogenase and
accumulation of α-AASA in blood, urine, and CSF,
thus providing a biologic marker for the disorder.
This enzyme is involved in lysine breakdown in the
brain and is believed to impact the metabolism of
the neurotransmitters glutamate and GABA.
11. Clues to etiology
Epilepsy syndromes.
Benign familial neonatal seizures— autosomal
dominant channelopathy, presents at 3– 7 days with
clonic seizures
Benign infantile neonatal seizures(“fifth day fits”)
present suddenly on days 4 to 6 of life, often with
frequent seizures leading to status epilepticus.
Seizures are initially focal clonic often with apnea.
Seizures usually cease within 2 weeks. The etiology
is unknown.
12. Clues to etiology
Epilepsy syndromes.
Early myoclonic epilepsy (EME),
often presenting in the first few days of life with
focal motor seizures andmyoclonus, which may be
subtle and erratic and usually affects the face and
limbs.
The seizures are very refractory to medications.
The EEG is characterized by aburst-suppression
pattern, which may only be seen in sleep, and, if
present throughout the sleep-wake cycle, is
exacerbated by sleep.
13. Clues to etiology
Epilepsy syndromes.
Early myoclonic epilepsy (EME),
This syndrome is often associated with underlying
metabolic disorders, for instance, glycine
encephalopathy (described earlier). Development is
severely affected, and many infants die, often within
their first year.
14. Clues to etiology
Epilepsy syndromes.
Early infantile epileptic encephalopathy (EIEE; Ohtahara
syndrome)
is also associated with very refractory epilepsy. In
contrast to EME, it is characterized by early onset of
tonic spasms along with focal motor seizures.
It, too, is associated with a burst-suppression
pattern on EEG, which is relatively invariant.
EIEE is more likely to be associated with structural
lesions.
Developmental prognosis is also poor in this
syndrome.
15. Clues to etiology
Malformations/structural lesions. Five percent of
neonatal seizures are caused by cerebral dysgenesis.
Cerebral dysgenesis can cause seizures from the first
day of life. This is most likely with the more severe
disorders such as hemimegalencephaly,
lissencephaly, and polymicrogyria. Seizures are
often refractory to medications.
16. Cerebral infarct.
Diffusion-weighted MRI
brain scan showing
restricted diffusion
(bright) corresponding to
a large left middle
cerebral artery territory
infarct involving much of
the frontal lobe.
17. MRI scan showing the
characteristic smooth
brain of an individual
with lissencephaly. It is a
basket term for a number
of congenital cortical
malformations
characterised by absent
or minimal sulcation.
18. Clues to etiology
Clues to neurocutaneous diseases may be apparent
on the newborn examination—for instance, the
hemangioma in the distribution of cranial nerveV1
in Sturge-Weber syndrome, which can occasionally
cause seizures in the newborn period.
Hypopigmented“ash-leaf” macules of tuberous
sclerosis may be seen, although neonatal seizures
are rare in this disorder.
Neuroimaging is primary in making these diagnoses.
19. Seizures in newborns are varied and subtle due to the
relative immaturity of the nervous system, and
generalized tonic– clonic seizures are rare.
Patterns of clinical seizures are:
Oculo- orofacial: eye rolling, eye deviation, staring,
nystagmus, chewing, sucking, lip smacking, smiling,
and blinking.
Central/ autonomic: change in breathing, apnoea,
desaturation, bradycardia.
20. Patterns of clinical seizures are:
Clonic: cycling or boxing movements, usually one
limb or side, may migrate to other limbs, 2– 4 Hz,
sharp- slow wave pattern on EEG, may be due to an
underlying focal lesion or a metabolic cause
Tonic: stiffening of the limbs or trunk usually
symmetrically and sometimes decerebrate or
opisthotonic posturing
Myoclonic jerks: fast movement, flexor muscles
Multifocal: more than one site, asynchronous,
migratory
21. •Generalized: bilateral, synchronous, non- migratory
Seizures must be differentiated from jitters.
•Jitteriness is a common, often normal finding, 5 Hz,
symmetrical tremor ofthe limbs, exacerbated by
startling, and terminated by holding/ flexing
thelimb, no ocular phenomena, no autonomic
changes, normal EEG.
22. Investigations
Bloods: glucose, blood gas, U&Es, Ca, Mg, FBC +
differential WCC, CRP, blood culture, congenital
infection screen.
Urine toxicology.
CSF (delay LP if baby is unstable) glucose, protein,
Gram stain, culture, viral PCR.
EEG (distinguish from non- seizure activity):
newborns often exhibit electro- clinical dissociation,
that is poor correlation between EEG changes and
clinical events. See Fig. 11.3.
23. Investigations
Neuroimaging: cranial USS (haemorrhage) and
consider CT/ MRI(cerebral malformations and
infarcts) if etiology remains unclear. SeeFig. 11.4
Consider genetic testing and referral if dysmorphic
or family history.
Consider metabolic screen if acidotic or family
history: ammonia, aminoacids, lactate, urine amino
and organic acids, +/ – CSF glucose, lactate,
and amino acids.
24. Management
Monitor breathing, which may be compromised
during seizures and following anticonvulsant
administration.
Rapidly identify and treat reversible causes
Hypoglycemia Dextrose 10%, 2-3 mL/kg IV
Hypocalcemia Calcium gluconate, 5% (50 mg/mL)
100-200 mg/kg IV; 10% (100 mg/mL) 50-100 mg/kg

Magnesium sulphate, 12.5% (125 mg/mL) 50-100
mg/kg IV
Commence antibiotics and add aciclovir if there is
any suspicion of herpes infection (e.g. maternal
25. Management
Commence antibiotics and add aciclovir if there is
any suspicion of herpes infection (e.g. maternal
infection, rash, abnormal LFTs).
26. Management
• Anticonvulsants
• The threshold for starting anticonvulsants is based on
both clinical condition and seizure duration and
frequency.
• Start an anticonvulsant if there are: prolonged
desaturations, haemodynamic instability, seizure
lasting>5 minutes, or brief but frequent seizures >3
per hour.
27. Management
• Anticonvulsants First- line:
phenobarbital ‘full’ loading dose (20 mg/ kg IV) • if
seizures continue for 30 min: give a further ‘half ’
loading dose of phenobarbital (i.e. 10mg/ kg IV) and
take blood for aphenobarbital level.
If seizures remain uncontrolled: either give further
‘half ’ loading dose of phenobarbital if blood levels
are low or consider adding another anticonvulsant.
Phenobarbital terminates seizures in up to 50% of
cases within a few hours.
28. Management
• Anticonvulsants Second- line:
phenytoin, loading dose (20 mg/ kg IV over 30 min),
may cause hypotension and arrhythmias if cardiac
function is impaired.
Give second dose if seizures not controlled after 20
min.
Phenytoin stops a further 15% of seizures.
29. Management
• Anticonvulsants Third- line:
clonazepam (10– 60 μg/ kg/ h IVI), midazolam (30–
50 μg/kg/ h IVI), lidocaine (4– 8 mg/ kg/ h IVI) NB
should not be used with phenytoin)), or
levetiracetam (initial dose 7 mg/ kg once daily).
It remains unclear which is the most effective agent
and the management of difficult to control seizures
should be discussed with a paediatric neurologist.
30. Management
• Anticonvulsants Fourth- line:
• consider 1 week trial of pyridoxine (100 mg od, po) if
• EEG shows a persistent spike and wave pattern and
poor response toprevious treatment.
• One week trial of pyridoxal phosphate (30 mg/
• kg/ 24 h po) if there is no response to pyridoxine.
Trial of creatine (300mg/ kg/ 24 h) + folinic acid (2.5
mg bd) + biotin (10 mg od) if seizures remain
uncontrolled
31. Management
if seizures remain uncontrolled
Use the minimum number of anticonvulsants
required to maintain seizure control
Some anticonvulsants cause respiratory depression
so breathing must bemonitored carefully.
32. Management
Maintenance treatment is not usually needed unless
there is evidence of an underlying seizure disorder:
If seizures persist use phenobarbital 3– 5 mg/ kg/
24 h IV or po in divided doses.
Most babies can stop anticonvulsants before
discharge home. However, those with persistent,
abnormal neurology may need to continue.
33. Outcome
Prognosis depends upon the underlying cause.
There is evidence that seizures in themselves and
status epilepticus in particular, are associated with
adverse neurodevelopmental sequelae.
34. toxins/Poisons
Toxic ingestions are uncommon in this age group,
but occasionally result from a maternal ingestion in
a breastfeeding mother, homeopathic remedies, or
overuse of accepted medications.
Although teething does not occur in the first month
of life, colic is a common concern at this point and
results in lost sleep and frustration.
Teething gels may be used as an attempt to relieve
distress for both parents and neonates.
Note that teething gels often contain benzocaine
which may cause methemoglobinemia with
overuse.
35. toxins/Poisons
Star anise tea:-
Used for relief of infantile colic.
Neurotoxicity.
Unexplained irritability.
Vomiting.
Seizures.
Baking soda:-
Used for intestinal gas cause serious toxicity.
36. toxins/Poisons
Management:-
ED management is primarily supportive, and will
depend on the clinical presentation.
Hospitalization for monitoring and observation is
recommended .
