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!

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

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

selection of preformed archwires during the alignment stage of preadjusted orthodontic fixed appliance.pptx
1. Selection of orthodontic
preformed archwires
during the alignment stage
of preadjusted fixed
appliance
Presented by
prof dr Maher Fouda
Mansoura Egypt
2. Stages of Straight Wire
Technique
1. Leveling and aligning.
2. Overbite reduction.
3. Overjet reduction and
space closure.
4. Finishing and occlusal
detailing.
3. Point 1: alignment is
the lining
up of teeth of an arch in
order to achieve normal
contact point
relationships.
4. Round flexible
archwires are
needed to
provide a gentle
continuous force
that is flexible
enough to
engage the
brackets on the
misaligned teeth
6. Point 2: It is beneficial to place
the bracket slightly in the
direction of the rotation to aid in
their correction.
7. Point 3:Alignment is
achieved by crown tipping
without root movement
alignment with NiTi arch-wires from 0.014-in
through to 0.018-in
8. Point 4 : Avoiding rectangular wires
during alignment to prevent round
tripping of the anterior teeth.
9. It is not necessary or even
advisable to use flexible
rectangular archwires for
initial alignment, as they may
place untoward forces on
root apices, potentially
causing greater patient
discomfort.
10. using flexible rectangular
archwires for initial alignment,
may also cause damage to the root
apices and, as labial crown torque
will begin to express in the
maxillary incisors, potentially
facilitating a loss of posterior
anchorage
11. Point 5 : archwire sleeve protecting tubing
or Mulligans bypass arch is used during
alignment stage in cases of severe incisor
crowding until space is availabe for their
alignment TO PREVENT ROUND TRIPING
MOVEMENT OF THE INCISORS .
Archwire sleeve protecting tubing Mulligan bypass arch
13. Roller coaster effect
also known as
vertical bowing
effect occurs when a
tooth ( e.g high and
labially placed
canine ) is brought
into the arch using a
light wire
Avoid roller coaster effect
A) Straight wire mechanics used
for canine extrusion.
B) Note the side effects on the lateral incisor
and first premolar, which made the conditions
of the case worse
14. loss of arch
length,
reduced
space in the
canine region
The net result is that
the adjacent teeth
will dip in and as a
result the eruption
space is compromise
Avoid
roller
coaster
effect
roller
coaster
effect
15. Five examples of
mechanics used
to extrude a
canine. (1) An
open coil spring
between the
lateral incisor and
premolar on 0.016-
inch stainless steel
wire maintains the
space while
preventing the
adjacent teeth
from tipping
Avoid roller coaster effect
16. .
(2) A cantilever
with a V-bend can
be used to move
the canine down.
The cantilever
should be
attached to the
canine with a
ligature at only
one point to avoid
unwanted moment.
Avoid roller coaster effect
18. (4) An
auxiliary
0.014 or
0.016 NiTi
wire can be
used along
with a
rectangular
SS main
archwire to
bring the
high
canine
down.
Avoid roller coaster effect
19. (5)A box loop produces a
statically indeterminate
force system. When used
for canine alignment,
it is constructed of .017"
x .025" TMA.
The activation of the box
loop depends on the
desired position of the
canine in both the
sagittal
and horizontal planes of
space
Avoid roller coaster effect
20. Canine retraction: In
this extraction case
avoid retracted canines
on flexible archwires,
the canines are
retracted on round
wires using elastic
chains.
Teeth tended to tip and
rotate into the extraction
sites when the chains were
overstretched, with
associated bite deepening.
Avoid roller coaster effect
21.
22. The clinician needs to recognize
the signs of excess force, such
as tissue blanching, patient
discomfort, and unwanted tooth
movements (for example roller
coaster effect), and take steps
to avoid these.
23. Essentially there is
a need for the
orthodontist to
use thin, flexible
wires early on,
with minimal
deflection, and to
avoid too frequent
archwire changes.
25. Initial flexible archwires tend to migrate
laterally along the dental arch
The wire will protrude from one side
while simultaneously coming out of
the opposite side molar tube
26. a–c Mechanical irritation of the mucosa caused by a continuous wire that has slipped
distally. The protruding wire part can cause considerable soft-tissue irritation
On the side that the wire is
protruding, it may cause ulceration
of the soft tissues, sometimes
leading to considerable patient
discomfort
27. Such unwanted
archwire
migration may
be prevented by
placing a stop
on the wire
between two
brackets that
are relatively
close together. Dimples positioned between the
centrals are designed to help with
accurate placement during ligation
MASEL
DIMPLED ARCHWIRES FROM 3M: AN
EXCELLENT CHOICE
28. Some wires
have crimpable
stops on them,
referred to as
crimpable split
tubes, which
just need to be
crimped into
the required
position .
3 Crimpable split tubes,
which may be crimped
onto the archwire with
Weingart pliers.
29. Alternatively, a
small bead of
flowable
composite resin,
known as a
composite stop,
may be run onto
the archwire in an
interbracket span
and light cured .
30. Neither of these
manoeuvres is
necessary if the
archwire is
either cinched or
bend backs are
placed distal to
the terminal
molars
Cinchback of Nitinol archwire
31. Bendback address the
common occurrence
of labial movement in
the anterior teeth.
Bending the archwire
back distal to the
terminal buccal tube
help to unify the arch,
and it also help
address patient
comfort distal to the
molars.
32. Bendback :If the
archwire is
bendback
immediately behind
the tube on the
most distally
bonded molar, this
serves to minimise
forward tipping of
incisors.
33. Bendback :In cases
where it is
necessary to
increase arch length
during levelling and
aligning and where
the A/P incisor
control is not
required, bend back
should be placed 1
or 2 mm distal to
the molar tube
34. In some patients,
particularly those
with deep bites,
well-interdigitated
occlusion and
potentially strong
jaw musculature,
the interdigitation
of the dental
occlusion
itself may be a
hindrance to initial
alignment. class II DIV 2
35. In such
situations, the
posterior teeth
may be
separated just
beyond the
resting vertical
dimension and
freeway space. The effect of ‘opening the bite’. Further
eruption of the incisors is limited while the
molars are encouraged to erupt to reduce the
overbite.
An upper removable appliance with a flat anterior
bite plane. The posterior teeth are out of occlusion,
providing space for eruption. The levelling effect
can be increased by placing a lower fixed appliance.
36. Such temporary
bite opening may
be achieved by
placing a
removable clip-
over anterior bite
plane, bonding a
composite resin
anterior bite
plane or
Acrylic
bite
plane
over an
acetate
.
Fixed
bite
plane
Bite ramps bonded to the upper central
incisors.
37. bite opening turbo props bonded palatal to
the maxillary central incisors .
39. Anterior bite opening
with a removable or
fixed bite plane permits
vertical clearance to
bond the mandibular
arch and permits easier
levelling of the
mandibular dental arch.
However, if there is an
increased incisor overjet,
posterior bite opening
may be required.
Posterior disclusion.
Fixed bite plane in mouth.
Patient with anterior deep bite
40. This may be
achieved by placing
glass ionomer
cement over the
occlusal surfaces of
the posterior molars,
usually the upper
molars, which makes
their subsequent
removal easier .
41. Glass ionomer cement bonded to (a)
occlusal surfaces of maxillary molars or (b)
mandibular molars, to open the anterior
bite.
42. With this latter
posterior bite opening
approach, it is
important that the
mandibular dental
arch
is bonded in order to
avoid uncontrolled
overeruption of
the mandibular
incisors
43. Point 7 :
There is no certain arch
wire sequence that
clinicians have to go
by.
44. Orthodontic Niti heat - activated arch wire
Body-Heat-Activated Nickel Titanium (ca 37°)
Extremely easy to ligate with lower ligating forces
Transforms to a super elastic state inside the mouth
Offering gentle continuous tooth-moving force
45. Innovations began with light
forces and heat-
activated/thermal NiTi
wires. These wires are soft
and pliable at room
temperature, which permits
easier insertion into the
bracket slots. As the wire
warms to mouth
temperature, (98 degrees,
+/- a few degrees), the wire
becomes more “active.”
46. The development of
copper nickel-titanium
wires, referred to as
'heat-activated' wires,
provided wires with
significantly greater
flexibility. As a result,
these wires could be
used as a substitute
for three of the
traditional stainless
steel wires in certain
situations, which was
a significant
improvement. initial .016 HANT wire was followed

wires on a per visit basis
during leveling and

be applied to the heat-
activated nickel-titanium
(HAN'T) wire in the areas
where full bracket

been achieved, and the
wire could be retied for
complete engagement.

48. The normal warmth of
the oral cavity
produced significant
activation of the wire-
and very efficient looth
movement.
Surprisingly, patients
did not seem to
complain of added
discomfort, probably
because of the light
forces that were
introduced.
Rectangular I IANT wires are very effective in
achieving tooth movements of this type in
this region. They give good control and do not
distort in response to masticatory forces

49. Nitinol Heat-
Activated
is a thermally
activated super-
elastic archwire.
It is the easiest
of Nitinol wires
to engage, and it
delivers light
continuous
forces that
effectively move
teeth with
minimal
discomfort to the
patient.
50. HE AT-ACTIVATED NICKEL-TITANIUM
(HANT) OR STAINLESS STEEL?
Because of their flexibilily, there
are clinical silualions where
heat-activated wires are not
recommended, or where some
stainless sleel wires should also be
used. These clinical
situations are described below:
Initial wires in cases with severe
malalignirient of teeth.
It is a service to the patient to
place a multistrand wire as
the first wire in such cases.
Initial alignment was
commenced with a .015
multistrand upper
archwire and a .016
HANT lower archwire. A
band w i th an eyelet
was placed on the
upper right lateral
incisor. This was loosely
tied.
51. HE AT-ACTIVATED NICKEL-TITANIUM
(HANT) OR STAINLESS STEEL?
The permanent deflection
that
occurs with these wires
reduces the overall force
levels and
produces less discomfort
during the initial
'experience with
braces'. Also, some wire
bending in addition to the
normal
arch form may be required,
and is easily accomplished
with multistrand wires.
Mid-sized
brackets were placed
wiih a .014 sectional
steel upper wire,
and a .016 lower
round HANT wire lo

52. Multi-Strand Archwires
3-strand wires are three
twisted strands of fine, round
Type 302SS that forma single
wire to provide light force,
good flexibility, and resiliency.
53. Multi-Strand Stainless
Steel archwires
This type of stainless
steel archwire is made
up of multiple 0.008
in SS wires coiled
together. There are 3
types: Coaxial,
Braided and or
Twisted. The coaxial
type of archwire
includes 6 strands of
0.008 in strands which
are coiled together.
DuraCore® SS Coaxial Archwire (5 wires
wrapped around a single core wire) is a super
resilient wire that can be bent to a greater
degree than ordinary twist wire – without
taking a set. Its resilience is most apparent
with severely malposed case. Coaxial wire is an
excellent initial archwire
54. Multi-Strand Stainless
Steel archwires
. The braided archwire
includes 8 strands and
twisted archwire
includes 3. These wires
can provide either a
round shape or
rectangular shaped
stainless steel wire.
The 8 Braid Archwire can reduce your
inventory by replacing twist wire, most round
wires and some rectangular wires during
treatment. The eight thin wires woven into a
strand becomes rectangular in its outer
dimension. It can be used for leveling and
effective control by filling the edgewise slot
with greater resiliency.
55. Multi-Strand Stainless
Steel archwires
The properties of these
wires are drastically
different from the
traditional stainless steel
archwires. They have low
stiffness and can be used
for initial leveling and
aligning stage in
orthodontics. However,
due to their lower elastic
limit they can be readily
deformed if acted upon by
any other force such as
food

56. Point 8 : Nitinol could
replace multistrand
arch wires in the
alignment stage
57. Nickel Titanium archwire
Nickel-titanium
(NiTi) wires are
preferred by
clinicians because
compared to
stainless steel
wires, they have a
wider working
range and higher
springback
properties.
Maxillary and mandibular .016
nickel‐titanium
arch wires have been placed. A
sectional .016 × .022 β‐titanium
wire was placed on the maxillary
right molar to canine for
retraction of the canine.
58. The introduction of
nickel-titanium
wires provided a
possible
substitute for
multistrand and
steel round wires
during the
leveling and aligning
stages of treatment.

59. POINT 9: One nickel
titanium
wire could be used in
place of approximately
two sizes of
stainless steel wires.
60. Point 10 : superelastic
Nitinol is better than
conventional Nitinol
wire is that engagement
of the displaced tooth is
readily achievable
61. Point 11 :
superelastic NiTi archwires
deliver a nearly light
constant force over a span
of activations—ideally those
that occur between office
visits and rapid tooth
movement results
62. Point 12 : Superelastic
Niti wire causes more
discomfort for the
patient comparing to
heat activated Niti.

86. Point 13 : it is important to
select prefabricated NiTi
archwires that are similar to
the patient arch form to
minimize changes and
reduce possible relapse .
87. Point 14 : It is
generally advised to
maintain the patient
arch
form during fixed
orthodontic treatment.
91. Arch Form
With this in mind,
3M provides
three distinct
arch forms that
reconcile the
variation
in anterior
curvature, inter-
cuspid width,
inter-molar width
and the curvature
from the cuspid
to the
second molars.
93. Tapered Arch Form:
This form is
especially ideal for
patients with
narrow arch forms
and gingival
recession in the
area of the cuspids
and bicuspids
(most frequently
found among
adults).
94. Tapered Arch
Form: Another
useful application
of this arch form
is in cases of
partial treatment
of only one arch,
as it will help
reduce the
occurrence of
expansion in the
treated arch
95. Ovoid Arch Form: With
an inter-cuspid width
between the other two
forms, this form is
intended, when
employed with the
retention and settling
steps , to maintain a
stable arch form post-
treatment.
97. Square Arch Form:
It can also be
applied early
in treatment in
cases that
require buccal
uprighting of
the lower
posterior
segments and
upper arch
expansion.
98. Square Arch
Form: If over-
expansion
occurs, it is
possible to
change to the
Ovoid arch
forms later in
treatment.

evidence in the
literature that
expansion in the
lower arch,
particularly in the
canine region is
unstable, and
little or no
evidence to the
contrary.

105. When the lower
arch is rolled in

is indicated for
stability

treatment.
110. Pre-
formed NiTi
archwires are
available in various
shapes
and sizes, and their
average intercanine
width could
exceed the natural
mandibular
intercanine width by
almost 6 mm.
111. Thus, it is
important to
select prefabri-
cated NiTi
archwires that
are similar to
the patient arch
form to
minimize
changes and
reduce possible
relapse.

114. Archform analysis
The maxillary
arch width in
the premolar
and molar
regions should
be assessed to
determine, if it
is narrow,
normal or
broad.
117. Archform analysis
The actual
measured values of
the interpremolar
(mesial occlusal pit
of first premolars
on either side) and
intermolar (mesial
occlusal pit of first
molar on either
side) widths are
compared to the
ideal values to
conclude whether
the arch is narrow,
normal or broad.
118. Clear templates
can be used to
assess the
patient's lower
model at the start
of treatment, to
determine
whether the lower
arch has a
tapered, square, or
ovoid form .
119. Arch form control early in
treatment
It is recommended that
all round wires be
stocked in ovoid form
only . this helps to limit
inventory. The opening
wires will normally be
.015 or ,0175 multistrand,
.016 HANT, or sometimes
.014 steel. These may all
be used in ovoid form,
with no customizing.
120. Arch form control early
in treatment
The manufatcured shape
of rectangular HANT wires
cannot be customized. It
is therefore necessary to
stock them in tapered,
square, and ovoid form,
because (like the heavier
round wires) they should
be used in the
approximate form for the
patient, as determined
using the clear templates.
121. Arch form control early
in treatment
Rectangular HANT
wires may be in place
for several months, and
they do influence the
patient's arch form,
especially in the
important canine
region. If not used in
the appropriate
tapered, square, or
ovoid shape, they can
cause undesirable
changes in the patient's
starting arch form
