The framework of the nose consists of bone and cartilage. Two small nasal bones and extensions of the maxillae form the bridge of the nose, which is the bony portion. The remainder of the framework is cartilage and is the flexible portion. Connective tissue and skin cover the framework.
Air enters the nasal cavity from the outside through two openings: the nostrils or external nares. The openings from the nasal cavity into the pharynx are the internal nares. Nose hairs at the entrance to the nose trap large inhaled particles.
Paranasal sinuses are air-filled cavities in the frontal, maxilae, ethmoid, and sphenoid bones. These sinuses, which have the same names as the bones in which they are located, surround the nasal cavity and open into it. They function to reduce the weight of the skull, to produce mucus, and to influence voice quality by acting as resonating chambers.

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

Dr Sujoy Dasgupta presented the study on "Couples presenting to the infertility clinic- Do they really have infertility? – The unexplored stories of non-consummation" in the 13th Congress of the Asia Pacific Initiative on Reproduction (ASPIRE 2024) at Manila on 24 May, 2024.
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

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.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

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!

2. The nose
External nose
Bony part
Carilagenous
part
Nasal cavity
1. floor 2.roof 3.lateral wall
4.medial (septal)
wall
3. External nose:-
- pyramidal in shape
- it has root continous with
forehead , and apex which
is its free edge.
- lateral surface of nose called
dorsum nasi, which end
below in rounded ala nasi .
- external nose compose of :
- - Bones
- Hyline cartilage
4. Morphology of External Nose
• The external nose has
two elliptical orifices
called the naris
(nostrils), which are
separated from each
other by the nasal
septum.
• The lateral margin, the
ala nasi, is rounded and
mobile.
5. • Lobule
the lower mobile portion of the nose
• Nares
symmetrically oval or elliptic and are directed obliquely toward the
nasal tip. the axes of the nostrils intersect just below the tip.
• Nasal Tip
The nasal tip is the nasal surface area contained within four
defining points, or landmarks, called tip defining points,the left
and right domes, the supratip breakpoint, and the columellar
breakpoint
• Nasal Facets (The soft tissue triangles)
span the area between the medial and lateral crura. This area of
facial skin opposes vestibular skin and is devoid of cartilage.
• Columella
The columella derives its appearance from the skin and
subcutaneous tissue covering the medial crura. As viewed from
the profile, the columella should be visible and project 2 to 3
mm below the alar rim. The base of the columella is widened
secondary to the flare of the medial crural footplates.
• Alar Base
Ideally, the width of the alar base corresponds to the width of
the intercanthal distance. The width of the alar base is related
to both the flare of the alae and the actual point of insertion at
the alar crease
7. Skeleton of External Nose
Bonny part :
- Nasal bone
- Frontal process of maxilla
- Nasal part of frontal bone
Cartilaginous part :
- Septal cartilage.
- Lateral nasal cartilage.
- Major alar cartilage.
- minor alar cartilage.
9. Nasal cartilages
Septal cartilage
• septal cartilage is quadrangular in
shape.
• It lays in the midline between the
nasal bones, the perpendicular
plate of the ethmoid superiorly,
and the vomer and palate
inferiorly.
• The septal cartilage is a major
support mechanism of the nose
and projects anteriorly to form
part of the dorsal profile.
10. Lateral cartilages
• The upper lateral cartilages
comprise the middle third of the
nose, or middle vault.
• They are trapezoidal in shape from
a lateral view, flaring out laterally
• it represent a transition zone from
the rigid nasal bones to the
flexible lower lateral cartilages.
• the nasal bones are attached to
and overlap the cephalic borders
of the upper lateral cartilages by
7–10 mm.
• supported by Fibrous connections
superior to the nasal bones,
medial to the cartilaginous
septum, and lateral to the
pyriform aperture.
11.
12. Alar cartilages
• These are C-shaped cartilages
typically divided into medial,
middle, and lateral crura
• These lower lateral cartilages
typically overlap the upper
lateral cartilages superiorly in
the scroll region
• Loose areolar tissue and
fibrous attachments connect
the upper and lower lateral
cartilages.
13. • The medial crura form
the cartilaginous support
for the columella
• Aesthetically, only 2–4
mm of columellar show
should be present below
the alar margins from a
profile View. Anything
more than this reflects a
“hanging columella” or
alar retraction.
• while any smaller
distance represents
columellar retraction.
14.
15. Blood Supply of the External Nose
• Blood supply of the nose derived from
branches of both the ECA & ICA
• The skin of the external nose is supplied by
branches of the ophthalmic and the maxillary
arteries.
• The skin of the ala and the lower part of the
septum are supplied by branches from the
facial artery.
16.
17. Nerve Supply of the External Nose
• The infratrochlear and external nasal
branches of the ophthalmic nerve (CN V)
and the infraorbital branch of the
maxillary nerve (CN V).
20. Internal valve
The junction of the
upper lateral cartilages
with the nasal septum
forms the internal nasal
valve. This valve angle
should be between 10
and 15° for adequate
nasal airflow
21. Nasal Cavity
It has :
1. floor
2.roof
3.lateral wall
4.medial (septal) wall
It has 3 region :
1. vestibular
2. olfactory
3. respiratory
22. Nasal vestibule:-
- dilation inside aperture of nostril
- bounded laterally by alar, and lower nasal cartilage.
- lined with skin, coarse hair and sebaceous gland ,
sweet gland .
- limited above and behind by curved elevation called
limen nasi.
Olfactory region :-
limited to superior nasal concha opposite part of septem ,
interventing roof. Present in roof , less vascular and
appear yellow in color.
Respiratory region:
The rest of cavity , very vascular red in color to warm the
air.
23. The Floor of Nasal Cavity
• Palatine process maxilla
• Horizontal plate
palatine bone
24.
25. The Roof of Nasal Cavity
• Narrow
• It is formed
– anteriorly beneath the bridge
of the nose by the nasal and
frontal bones,
– in the middle by the
cribriform plate of the
ethmoid,
– located beneath the anterior
cranial fossa,
– posteriorly by the downward
sloping body of the sphenoid
26. The Medial Wall of Nasal Cavity
The Nasal Septum
• Divides the nasal cavity into
right and left halves
• It has osseous and
cartilaginous & soft tissue
parts
• Nasal septum consists of
1- Bony septum :consists of the
perpendicular plate of the
ethmoid bone (superior), the
vomer (inferior)
2- Septal cartilage (anterior)
3- Membranous septum : fibrous
tissue attaching the septal
cartilage to the medial crura
Perpendicular
Plate (ethmoid)
Septal
Cartilage
Vomer
Nerve supply of nasal septum :
Anterior superior part by anterior ethmoidal
nerve
Posterior inferior part by sphenopalatine nerve
28. The Lateral Walls of Nasal Cavity
- it is formed from :
1- medial surface of
maxilla.
2- ethmoid bone :
- superior concha
- middle concha
3- inferior concha.
4- lacrimal bone.
5- perpendicular plate of
palatine.
6- medial pterygoid plate.
29. The Lateral Walls of Nasal Cavity
Superior meatus and concha:-
- it is shortest , shallowest of 3 meatus.
- behind superior meatus is sphenopalatine
from a men which open into ptergo palatine
fossa.
Middle concha and meatus :-
- much larger articulated with perpendicular
plate of palatine bone.
- at its upper part occupy by elevation called
bulla ethmaidal which contain middle
ethmaidal air cells. The opening of maxillary
sinus is situated below bulla ethmaidal near the
posterior end of hiatus semilunaris.
- hiatus semilunaris which leads upward and
fore ward into curved chaunel called ethmaidal
infundibalam , in which anterior ethmaid sinus
open in infundibalam .frontal sinus open
through infundibalam into anterior end of

32.
33. Blood Supply to the Nasal Cavity
• From branches of the maxillary artery, one of the
terminal branches of the external carotid artery.
• The most important branch is the sphenopalatine
artery.
• The sphenopalatine artery anastomoses with the
septal branch of the superior labial branch of the
