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!

6. Mastoiditis
• It is the inflammation of mucosal lining of mastoid antrum
and air cells system.
• Pathology
o Production of pus under tension
o Hyperaemic decalcification
o Osteoclastic resorption of bony walls
6
7. Clinical Features
• Otorrhoea > 2 weeks, otalgia & deafness
• Mastoid reservoir sign: pus fills up on mopping
• Sagging of postero-superior canal wall
• Ironed out appearance of skin over mastoid due to
thickened periosteum
• Mastoid tenderness
Investigation
• X-ray & CT scan
7
13. • Seen in AOM,COM(both mucosal and squamosal
variety)
• Predisposing factors:
1.congenital dehescence of FC
2.canal erosion by cholesteatoma/granulation
13
17. • Serous labyrinthitis occurs during acute or chronic
otitis media. It is presumed that bacterial exotoxins
enter the inner ear via the oval or round window or a
labyrinthine fistula.
• there is no clinical method for differentiating serous
from suppurative labyrinthitis. If vestibular and
auditory functions are partially or completely
retained, it can be assumed that the infection was
serous.
17
20. • Spread of infection from middle ear and mastoid to the
(peumatised) petrous part of temporal bone.
• Petrous bone are of three types;
1.Well peumatised(25-30%)
2. Diploic
3. Sclerotic(Most common)
20
21. Gradenigo syndrome
• It is triad of,
• Persistent otorrhoea
• Retro-orbital pain: Trigeminal nerve involvement
• Diplopia: Convergent squint due to lateral rectus palsy
by injury to abducent nerve
21
22. Etiology:
• mastoiditis involving petrous apex along postero-
superior & anteroinferior tracts in relation to bony
labyrinth
• Anteroinferior tract : starts at the hypotympanum
near the eustachian tube runs around the cochlea to
reach the petrous .
• Posterosuperior tract :starts in the mastoid and
runs behind or above the bony labyrinth to the
petrous apex.
22
23. Diagnosis:
• C.T. scan temporal bone
• M.R.I. to differ b/w bone marrow & pus
Treatment:
• Modified radical mastoidectomy & clearance of petrous
apex cells
23
25. Pathology
Production of pus under tension
hyperaemic decalcification (halisteresis)
osteoclastic resorption of bone
sub-periosteal abscess
penetration of periosteum + skin
fistula formation
25
29. • Luc: swelling in external auditory canal
• Bezold absceses-swelling over sternocleidomastoid
muscle
• Citelli absceses-swelling over posterior belly of
digastric muscle
• Parapharyngeal & Retropharyngeal: due to spread of
pus along Eustachian tube
29
31. Meningitis
It defined as inflammation of leptomeninges (Pia &
Arachnoid) with bacterial invasion of CSF in
subarachnoid space.
31
32. Mode of invasion
• Preformed pathway (patent petro squamus suture or
labyrinth)
• Venous thrombophlebitis
• Direct erosion of bone by cholesteatoma
32
33. Clinical features
1. Fever with chills and rigor
2. Headache
3. Neck rigidity
4. Photophobia, irritability
5. Nausea, Vomiting
33
34. On examination
1. Kernig’s sign– Extension of leg with thigh flexed
causes pain
2. Brudzinski’s sign– Flexion of neck causes flexion
of hip and knee.
3. Exaggerated tendon reflex
4. Papilloedema
34
35. Otogenic brain abscess
• 50-70 % adult & 25% in child abscess are otogenic
• Route of infection:
1. Direct spread:
• via Tegmen plate: Temporal abscess
• via Trautmann’s triangle: Cerebellar abscess
2. Retrograde thrombophlebitis
35
36. Trautmann’s Triangle
• Superiorly: superior
petrosal sinus
• Posteriorly: sigmoid sinus
• Anteriorly: semi-circular
canals)
• Pathway to posterior
cranial fossa from
mastoid cavity
36
37. Stages of Brain Abscess
• Early cerebritis(invasion)- 1-3 days
• Late cerebritis(Localization)-4-10days
• Early capsule formation(Enlargement)-10-13 days
• Late capsule formation(termination)-14 days.
37
40. Surgical Treatment
• Repeated burr hole aspirations
• Excision of brain abscess with capsule
• Open incision & evacuation of pus
• Radical mastoidectomy after pt becomes stable
40
41. Otitic Hydrocephalus
• Defined as raised intracranial pressure with normal
CSF finding
• Seen in children and adolescent with acute and
chronic middle ear infection
41
42. Mechanism
Retrograde extension of thrombophibittis from
sigmoid sinus to superior sagittal sinus
Blockage of arachnoid villi
Dec CSF absorption/Inc Secretions
Raised CSF pressure
42
43. Symptoms
• Severe headache,
• Drowsines
• Vomiting
• Blurring of vision,Diplopia
Signs
• Papilloedema
• Nystagmus
• CSF pressure > 300 mm of water.
43
45. Extradural Abscess
• It is collection of pus between dura matter and the
bone of the IC
Pathology
• Bone over the dura destroyed by decalcification
(Acute) or cholesteatoma (Chronic)
• Spread of infection by venous thrombophlebitis
Clinical features
1. Persistent headache
2. Severe pain in the ear
3. Low grade fever and malaise.
45
46. Subdural abscess
• Collection of pus between dura and arachnoid
• Erosion of bone and dura by thrombophlebitic
process
• Pus may get loculated at various places in subdural
space
Clinical features –
1. Due to meningeal irritation – Fever, malaise,
headache, neck rigidity, positive kernig’s sign
2. Due to raised intra cranial tension – papilloedema,
ptosis.
46
47. Lateral sinus thrombosis
• Syn – Sigmoid sinus thrombosis
• Definition – It is an inflammation of inner wall of
lateral venous sinus with thrombus formation.
• Aetiology –CSOM with cholesteatoma.
47
48. Pathology
1. Formation of perisinus abscess(outer wall sinus)
2. Endophlebitis and mural thrombus formation(inner
Wall)
3. Thrombus enlarges to Obliterate the sinus lumen
and leads to intrasinus abscess
4. Extension of the thrombus-Septicemia.
