Congenital hypothyroidism is the most common neonatal metabolic disorder and can cause severe physical and neurological impairment if left untreated. It occurs in approximately 1 in 3,000-4,000 births. The thyroid gland normally develops between weeks 3-7 of gestation and begins secreting hormones around week 12. After birth, there is a surge in TSH levels in response to cooling which returns to normal after 3 days. Congenital hypothyroidism can be primary, from defects in the thyroid gland itself, or secondary, from deficiency in TSH. The most common cause is developmental defects of the gland such as hypoplasia or aplasia. Treatment involves lifelong levothyroxine replacement therapy.

Congenital hypothyroidism is quite common in Indians and is the most common reversible congenital cause of mental retardation.
Early identification and intervention is important as Thyroid dependent brain development is complete by 3 years of age.
Universal screening is ideal as most cases are sporadic.
Positive cases on screening by filter paper test should be confirmed by serum levels estimation.
Serum Thyroid hormone levels are of primary importance in diagnosing and managing this condition, other investigations are ancillary.
Age based reference values must be followed in interpreting the results.
Timely monitoring (serum hormone levels, compliance, growth & development) and adequate counseling of care givers are key in managing this condition.
Hyperthyroidism is a very common name, when it comes to lifestyle diseases. Often a deeper and holistic approach towards your health will help you find long term solution, and hence you will be able to recognize your symptoms of Hyperthyroidism. Your thyroid gland, when starts secreting more amount of hormone, the condition is referred as hyperthyroidism. Thereby speeding up the bodily functions, including metabolism.

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
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.

Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
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!
NVBDCP.pptx Nation vector borne disease control programSapna Thakur
NVBDCP was launched in 2003-2004 . Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding arthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
2. Congenital hypothyroidism is the most
common neonatal metabolic disorder and
results in severe physical and
neurodevelopmental impairment and
infertility if untreated.
The incidence 1:3000-4000.
3. Around third week the thyroid gland develops as
epithelial proliferation between body and root of
the tongue- foramen cecum. It descends as
bilobed diverticulum in front of pharyngeal gut
still connected to it by the thyroglossal duct
(disappear later).
Migration continues to the definitive position in
front of the trachea by 7 week.
4. The gland started to secrete hormone around 12
week. Maternally T4 crosses the placenta in
physiologically significant amounts, which
explains the relatively normal phenotype in
hypothyroid infants.
After birth there is an acute discharge of TSH
provoked by cooling -peak at 30 min, return to
normal after 3 days.
5. Thyroid hormone increase oxygen
consumption, stimulate protein synthesis,
influence growth and maturation and
affects carbohydrate, lipid and vitamins
metabolism
6. Classification of congenital hypothyroidism:
1-primary where the problem arises from the gland
itself.
A- developmental defects.
B- inborn errors of thyroid hormone synthesis.
C- maternal exposure to specific agents
D- iodine deficiency
7. 2-secondary hypothyroidism -TSH deficiency.
3-tertiary hypothyroidism –TRH deficiency.
Sometimes may be associated with other
hormone deficiencies.
8. Developmental defects:
most common cause of congenital
hypothyroidism accounts for approximately 85%.
These defects may be hypoplasia of the gland or
compete aplasia.
Sometimes abnormally located gland (ectopic).
9. Ectopic gland is the most common form of
thyroid dysgenesis.
Its almost two third of developmental
disorders.
Sometimes can discovered later either when
fails to maintain adequate secretion of
hormone or appears as swelling along the
tract.
10. Exact cause is not known but familial cases
occasionally reported.
Three transcription factors (TTF-1,FOXE1,PAX-8)
are important for thyroid morphogenesis,
mutation in these factors can lead to thyroid
dysgenesis.
NKX2.1 found in both thyroid and CNS these
children expressed hypothyroidism and persistent
neurological problems despite early treatment.
Pendred syndrome due to sulfate transport
protein common to thyroid and cochlea.
11. Inborn errors of thyroid hormone synthesis :
autosomal recessive inheritance.
second commonest cause accounting for about
10% of identified cases by screening.
Presence of goiter at birth is strongly suggestive
but may develop later.
A defect may occur at any biosynthetic step.
12.
13. Iodide transport defects due to mutation in
sodium iodide symporter.
Peroxidase deficiency most common defect
important in organification and coupling.
Thyroglobulin synthesis.
deficiency in deiodination.
Thyroid hormone transportation and
unresponsiveness also play role.
14. Clinical presentation:
risk factors-family history, birth defects, female
gender, GA> 40 weeks.
Presentation can be classified as
1-early presentation.
2-late presentation .
15. Early presentation:
prolonged gestation, LGA, large fontanelles.
Respiratory distress syndrome, delayed bone age,
umbilical hernia and goiter.
By 2 weeks: hypotonia, lethargy, constipation,
hypothermia, prolonged jaundice, mottling,
abdominal distension, feeding difficulties.
16.
17. Late presentation:
classically appears after 6 weeks and include
puffy eye lids, coarse hair, large tongue,
myxedema, and hoarse cry. In borderline cases
presentation may be significant hearing
impairment and speech delay.
18. Investigations:
Thyroid hormone assay
Neonatal screening programs
1-North America T4 with TSH backup
2-European and Japanese based on measurement
of TSH
special care should be given to normal values
according to age of neonate.
19. Imaging:
retardation of osseous development can be seen
in up to 60% of affected infants.
In undetected or untreated patients discrepancy
between chronological age bone age increases.
20.
21. Ultrasonography and Scintigraphy:
ultrasonographic examination is helpful
but may miss some ectopic glands.
Scintigraphy can pinpoint the underline cause.
123I sodium iodide is preferred.
Treatment should not be delayed for this study.
24. Treatment:
levothyroxine is the treatment of choice.
80% of circulating T3 is formed from T4 and same
in the brain.
Recommended dose between 10-15 microg.
Severe manifestation MAX dose.
Thyroxine tabs should not be mixed with soy
protein formulas or iron.
T4 and TSH should be followed regularly.
25. If suspicion of transient hypothyroidism is
there discontinuation of therapy for 3-4
weeks can be tried at age of three.
26. Prognosis:
mainly depend on early diagnosis, rapid
correction of hypothyroxinemia,and compliance
to therapy in the first 2-3 years.
If proper management started early thase
children have normal linear growth and
intelligence.
Severely affected ones may experience
developmental problems.
