====Acute Sinusitis====
{{Endocarditis}}
[[Acute (medical)|Acute]] sinusitis is usually precipitated by an earlier [[upper respiratory tract infection]], generally of [[virus|viral]] origin.
Virally damaged surface tissues are then colonized by [[bacteria]], most commonly ''[[Haemophilus influenzae]]'', ''[[Streptococcus pneumoniae]]'', ''[[Moraxella catarrhalis]]'' and ''[[Staphylococcus aureus]]''. Other [[bacterial]] [[pathogen]]s include other [[streptococci]] [[species]], [[Anaerobic organism|anaerobic bacteria]] and, less commonly, [[gram negative]] bacteria.
Another possible cause of sinusitis can be dental problems that affect the maxillary sinus.
[[Acute (medical)|Acute]] episodes of sinusitis can also result from [[fungus|fungal]] invasion.
These [[infection]]s are most often seen in [[patient]]s with [[diabetes]] or other [[immunodeficiency|immune deficiencies]] (such as [[AIDS]] or [[transplant]] [[patient]]s on anti-rejection medications) and can be life threatening. In type I diabetes, ketoacidosis causes sinusitis by [[Mucormycosis]].

==Overview==
====Chronic Sinusitis====
Early valve surgery should be scheduled when there is [[heart failure]] due to the valve dysfunction, left-sided infective endocarditis due to ''[[Staphylococcus aureus]]'', fungal or highly resistant organisms, or a [[heart block]], annular or aortic [[abscess]] or destructive lesions.  Other indications include persistent [[bacteremia]] or [[fever]] 5 to 7 following the initiation of the [[antibiotic]]s, relapse of the infection depsite a complete course of antibiotics in [[prosthetic valve]] endocarditis when no portal of infection can be identified, recurrent emboli and persistent vegetations despite [[antibiotic therapy]], and mobile vegetations with a length more than 10 mm in native valve endocarditis.  Surgical removal of the [[valve]] is necessary in patients who fail to clear micro-organisms from their blood in response to [[antibiotic]] therapy, or in patients who develop [[cardiac failure]] resulting from destruction of a [[valve]] by [[infection]]. A removed valve is usually replaced with an artificial valve which may either be mechanical (metallic) or obtained from an animal such as a pig; the latter are termed bioprosthetic valves.<ref name= Baddour>{{cite journal | author = Baddour Larry M., Wilson Walter R., Bayer Arnold S., Fowler Vance G.

Chronic sinusitis is a complicated spectrum of diseases that share chronic inflammation of the sinuses in common. The causes are multifactorial and may include allergy, environmental factors such as dust or pollution, bacterial infection, and/or fungus (either allergic, infective or reactive). Non allergic factors such as [[Vasomotor rhinitis]] can also cause chronic sinus problems.  


==Surgery==
Symptoms include: [[Nasal congestion]]; facial pain; [[headache]]; [[fever]]; general [[malaise]]; thick green or yellow [[Rhinorrhea|discharge]]; feeling of facial 'fullness' worsening on bending over; aching teeth. 


===Indications===
Very rarely, chronic sinusitis can lead to [[anosmia]], the inability to [[olfaction|smell]] or detect odors.
Indications for surgical debridement of vegetations and infected perivalvular tissue, with valve replacement or repair as needed are listed below:<ref name= Baddour>{{cite journal | author = Baddour Larry M., Wilson Walter R., Bayer Arnold S., Fowler Vance G.

In a small number of cases, chronic [[maxillary]] sinusitis can also be brought on by the spreading of bacteria from a dental infection.

Attempts have been made to provide a more consistent nomenclature for subtypes of chronic sinusitis. A task force for the American Academy of Otolaryngology - Head and Neck Surgery / Foundation along with the Sinus and Allergy Health Partnership broke Chronic Sinusitis into two main divisions, Chronic Sinusitis without polyps and Chronic Sinusitis with polyps (also often referred to as Chronic Hyperplastic Sinusitis). Recent studies which have sought to further determine and characterize a common pathologic progression of disease have resulted in an expansion of proposed subtypes. Many patients have demonstrated the presence of [[Eosinophil granulocyte|eosinophils]] in the mucous lining of the nose and paranasal sinuses. As such the name Eosinophilic Mucin RhinoSinusitis (EMRS) has come into being. Cases of EMRS may be related to an allergic response, but allergy is often not documentable, resulting in further subcategorization of allergic and non-allergic EMRS.


{|class="wikitable"
A more recent, and still debated, development in chronic sinusitis is the role that [[fungus]] may play. Fungus can be found in the nasal cavities and sinuses of most patients with sinusitis, but can also be found in healthy people as well. It remains unclear if fungus is a definite factor in the development of chronic sinusitis and if it is, what the difference may be between those who develop the disease and those who do not.

*Excision of all infected [[valve]] tissue
*Drainage and debridement of [[abscess]] cavities
*Repair or replacement of damaged valves
*Repair of any associated pathology such as septal defect, [[fistula]]s
 
==Aortic Valve - Surgical Options==
If the [[infection]] is limited to the leaflets, then the [[aortic valve]] should be replaced.  If the infection extends to the anulus or beyond, then the infected tissues should be debrided.  Any abscesses should be drained and the aortic root should be replaced.
 
==Atrioventricular Valve - Surgical Options==
If the infection is limited to the leaflets, then the vegetations should be excised, perforations should be repaired, and a reduction annuloplasty should be performed.  If the infection extends to the anulus or beyond, then a valve replacement should be performed, and abscesses should be debrided and obliterated. In some cases the tricuspid valve may be excised.
 
==Surgical Outcomes==
Operative mortality is 15 - 20%. The development of an infection of a prosthetic valve during operation for [[endocarditis|native valve endocarditis]] is 4%, it is higher (12 - 16%) if active [[endocarditis]] is present at the time of the surgery.

Acute Sinusitis

Acute sinusitis is usually precipitated by an earlier upper respiratory tract infection, generally of viral origin. Virally damaged surface tissues are then colonized by bacteria, most commonly Haemophilus influenzae, Streptococcus pneumoniae, Moraxella catarrhalis and Staphylococcus aureus. Other bacterial pathogens include other streptococci species, anaerobic bacteria and, less commonly, gram negative bacteria. Another possible cause of sinusitis can be dental problems that affect the maxillary sinus. Acute episodes of sinusitis can also result from fungal invasion. These infections are most often seen in patients with diabetes or other immune deficiencies (such as AIDS or transplant patients on anti-rejection medications) and can be life threatening. In type I diabetes, ketoacidosis causes sinusitis by Mucormycosis.


Chronic Sinusitis

Chronic sinusitis is a complicated spectrum of diseases that share chronic inflammation of the sinuses in common. The causes are multifactorial and may include allergy, environmental factors such as dust or pollution, bacterial infection, and/or fungus (either allergic, infective or reactive). Non allergic factors such as Vasomotor rhinitis can also cause chronic sinus problems.

Symptoms include: Nasal congestion; facial pain; headache; fever; general malaise; thick green or yellow discharge; feeling of facial 'fullness' worsening on bending over; aching teeth.

Very rarely, chronic sinusitis can lead to anosmia, the inability to smell or detect odors.

In a small number of cases, chronic maxillary sinusitis can also be brought on by the spreading of bacteria from a dental infection.

Attempts have been made to provide a more consistent nomenclature for subtypes of chronic sinusitis. A task force for the American Academy of Otolaryngology - Head and Neck Surgery / Foundation along with the Sinus and Allergy Health Partnership broke Chronic Sinusitis into two main divisions, Chronic Sinusitis without polyps and Chronic Sinusitis with polyps (also often referred to as Chronic Hyperplastic Sinusitis). Recent studies which have sought to further determine and characterize a common pathologic progression of disease have resulted in an expansion of proposed subtypes. Many patients have demonstrated the presence of eosinophils in the mucous lining of the nose and paranasal sinuses. As such the name Eosinophilic Mucin RhinoSinusitis (EMRS) has come into being. Cases of EMRS may be related to an allergic response, but allergy is often not documentable, resulting in further subcategorization of allergic and non-allergic EMRS.

A more recent, and still debated, development in chronic sinusitis is the role that fungus may play. Fungus can be found in the nasal cavities and sinuses of most patients with sinusitis, but can also be found in healthy people as well. It remains unclear if fungus is a definite factor in the development of chronic sinusitis and if it is, what the difference may be between those who develop the disease and those who do not.
