1. Chronic sinusitis is defined as sinus inflammation lasting over 3 months, usually due to inadequately treated acute or subacute sinusitis.
2. The maxillary sinus is most commonly infected due to its poor drainage and narrow ostia.
3. In multisinusitis/pansinusitis, treatment should focus on the maxillary sinus first to improve drainage of other sinuses.
4. In recurrent sinusitis in children, the most common cause is adenoid hypertrophy and other nasal obstructions that impair mucus drainage.

Rhino-sinusitis: inflammation of lining mucosa of nose & paranasal sinuses
Acute: infection lasting < 4 weeks
Sub acute: infection lasting 4 to 12 weeks
Chronic: infection lasting > 12 weeks
Recurrent acute (RARS): > 4 episodes in a year, each episode lasting for 7-10 days, without persistent symptoms in between
Etiology:
Rhinogenic: commonest (85%), following any form of rhinitis
Dental: root abscess, dental procedures (maxillary sinusitis)
Trauma:
Accidental: R.T.A., swimming, diving, F.B., barotrauma
Iatrogenic: nasal packing, septal surgery
Hematogenous : rare
Symptoms
Nasal discharge : mucoid / purulent / blood-stained
Nasal obstruction with hyposmia / anosmia
Headache and facial pain
Cheek / eyelid congestion and swelling
Hawking, sore throat, dry irritating cough
Earache: associated Eustachian tube dysfunction
Constitutional: fever, malaise, body ache
Rhinosinusitis Task Force Criteria (RI 2004)
Location of facial pain in sinusitis
Maxillary sinusitis
Cheek, upper jaw, forehead that increases on bending forward
Frontal sinusitis
Pain over the forehead that increases during morning and decreases by late afternoon (office headache)
Anterior Ethmoid : nasal bridge and peri-orbital, more on eye movement
Posterior Ethmoid : deep seated retro-orbital
Sphenoid : vertex, occipital, retro-orbital pain
Palpation to elicit paranasal sinus tenderness
Maxillary: over the canine fossa
Anterior ethmoid: medial to medial canthus
Frontal: Floor of sinus at the superomedial aspect of the orbit or tap over its anterior wall on the forehead
Postural tests for rhinosinusitis
Performed in acute sinusitis (active nasal discharge)
Pus cleaned in supine position & patient sits upright
Pus appears : frontal or ethmoid sinusitis
Pus appears on stooping forwards: sphenoid sinusitis
No discharge patient lies in lateral position with affected side up
Pus appears: maxillary sinusitis

Nasal Polyps are defined as pale, polypoidal, pedunculated , prolapsed sinus mucosa into the nose.
They cause nasal obstruction. Nasal allergy and infecions are proposed to be the most common etiological factors for nasal polyps.
This presentation explains in detail about every aspect of nasal polyps.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2. Recap -- Acute Sinusitis
• Acute inflammation of sinus mucosa
• Most common – Max Ethmoidal
Frontal Sphenoidal
• Multisinusitis / pansinusitis
• ‘Open’ / ‘Closed’ Sinusitis
3. DEFINITIONS/ CONCEPTS
• Acute sinusitis- disease lasting less than one
month
• Subacute sinusitis - disease lasting 1 to 3
months
• Chronic sinusitis - disease lasting more than
three months; usually due to inadequately
treated acute or subacute disease
• Treatment concepts- Ac/subacute sinusitis
• - Chronic sinusitis
4. DEVELOPMENT
• Development of Sinuses
– At Birth – Max/ Ethmoidal
– Floor of nose higher than max sinus
floor till about 10 yrs
– Radiologically – Max (5m), Ethm (1yr),
Frontals (6 yrs)
6. PHYSIOLOGY
• Lining - pseudostratified, columnar epithelium
(respiratory epithelium)
• Mucous blanket is in two layers: a superficial
viscous layer and an underlying serous layer.
• Muco-ciliary blanket follows definite pathways
• Normal function depends on patent ostia,
ciliary function and quality of mucus
7. PATHOPHYSIOLOGY
• Vicious Cycle
• Obstruction leads to hypo-oxygenation
• Hypo-oxygenation leads to ciliary
dysfunction and poor mucous quality
• Ciliary dysfunction leads to retention of
secretions
11. RADIOLOGY
• Plain films –more useful in acute
sinusitis, help in evaluating size and
integrity of the paranasal sinuses
• CT scan- the study of choice in chronic
sinusitis
12. PLAIN FILMS
• Three general views: Waters’,
Caldwell’s and lateral
• Waters’ view with nose and chin on film.
Useful for maxillary sinuses
• Caldwell view with nose and forehead
on film. Useful for frontal and ethmoid
sinuses
• Lateral film useful for sphenoid sinuses
19. MANAGEMENT
• Principles of Rx
– Reversible State
• Est drainage
• Control infection
– Antibiotics, Decongestants, Steam inhalation
– Lavages – if reqd - FESS
– Irreversible State
• Remove chr inf mucosa
• Est drainage
• Basically surgery reserved for severe chr
infections, mucosal changes ++, failure of
conservative Rx, sinusitis with complications
21. Ac Ethmoidal Sinusitis - Complications
• Orbital Cellulitis/ Abscess
• CST (Cavernous Sinus Thrombophlebitis)
• CNS Complications
22. Ac Frontal Sinusitis - Complications
• Orbital Cellulitis
• Osteomyelitis frontal bone
• Intracranial complications
• Chronic Frontal Sinusitis
23. • Why Max Sinus is infected commonly?
• In Multisinusitis/ Pansinusitis which sinus
should you focus on?
• In recurrent sinusitis in children, you should
aim to find out the cause. Commonest
cause?
• Why are orbital complications commonest
in children?
• Osteomyelitis of sinus bones is commonest
in maxilla & frontal bones. Why?
• Present concept of Surg Rx?
