Bacterial infections sinusitis

Cystic fibrosis (CF) is a recessive genetic disorder prevalent among whites in North America and certain parts of northern Europe. It is characterized by chronic bacterial infections of the airways and sinuses, fat maldigestion due to pancreatic exocrine insufficiency, infertility in males due to abnormal development of the vas deferens, and elevated levels of chloride in sweat (> 60 mmol/L). 

Although viral infections are important causes of both otitis media and sinusitis, they are generally self-limiting. Bacterial infections m complicate viral illnesses, and are also primary causes of ear and sinus infections. Streptococcus pneumoniae and Haemophilus influenzae are the commonest bacterial pathogens. Amoxycillin is widely prescribed for these infections since it is microbiologically active, penetrates the middle ear, and sinuses, is well tolerated and has proved effective. 

Routine antibiotic use is not warranted because the primary infectious agents associated with asthma exacerbations are viruses.2,3 Antibiotics should be reserved for situations when bacterial infection is strongly suspected (e.g., fever and purulent sputum, pneumonia, and suspected sinusitis). 

Sinusitis, or inflammation of the paranasal sinuses, is better described as rhinosinusitis that also involves inflammation of contiguous nasal mucosa, which occurs in virtually all cases of viral respiratory infections. Acute rhinosinusitis is characterized by symptoms that resolve completely in less than 4 weeks, whereas chronic rhinosinusitis typically persists as cough, rhi-norrhea, or nasal obstruction for more than 90 days. Acute bacterial rhinosinusitis (ABRS) refers to an acute bacterial infection of the sinuses that can occur independently or be superimposed on chronic sinusitis. The focus of this section will be on ABRS and appropriate treatment. 

How long have the patient s symptoms been present If symptoms are mild and present for fewer than 10 days, viral sinusitis is likely. Persistent moderate or acute severe symptoms are more indicative of bacterial infection. 

Upper respiratory tract infection Sinusitis, bronchitis, or otitis caused by viral or bacterial infections. 

Serious adverse events occur in up to 6% of patients with anti-TNF therapy. The most important adverse effect of these drugs is infection due to suppression of the ThI inflammatory response. This may lead to serious infections such as bacterial sepsis, tuberculosis, invasive fungal organisms, reactivation of hepatitis B, listeriosis, and other opportunistic infections. Reactivation of latent tuberculosis, with dissemination, has occurred. Before administering anti-TNF therapy, all patients must undergo purified protein derivative (PPD) testing prophylactic therapy for tuberculosis is warranted for patients with positive test results. More common but usually less serious infections include upper respiratory infections (sinusitis, bronchitis, and pneumonia) and cellulitis. The risk of serious infections is increased markedly in patients taking concomitant corticosteroids.

Some research has concluded that in certain patients a cascading effect occurs. Eosinophils cluster around the fungi in the respiratory tract and produce toxins to subdue the fungi. In sinusitis, these toxins also destroy the outer lining of the sinus tissue, clearing the way for a bacterial infection that causes inflammation and sinusitis. 

Recovery is usually within 4-10 days, although complications - laryngitis, sinusitis and otitis media - may follow and become complicated by secondary bacterial infection... 

Viral and bacterial sinusitis are difficult to differentiate because their clinical presentations are similar. Viral infections, however, tend to resolve by 7 to 10 days. Persistence of symptoms beyond this time likely indicates a bacterial infection. 

Loracarbef, a synthetic beta lactam antibiotic of the car-bacephem class (200 to 400 mg p.o. q. 12 hours), is used in the treatment of secondary bacterial infections of acute bronchitis, acute bacterial exacerbations or chronic bronchitis, of pneumonia, pharyngitis, tonsillitis, sinusitis, acute otitis media, uncomplicated skin and skin-structure infections, impetigo, uncomplicated cystitis, and in uncomplicated pyelonephritis. 

No. These drugs decrease secretion, causing discharged fluid to have increased viscosity and remain in the sinus cavities for a longer period of time. Since one physiologic purpose of the drainage is to remove bacteria and toxins from the sinus cavities, administration of antihistamines allows the accumulation of these bacteria and may precipitate the onset of a bacterial infection. 

Goldenseal seems best when used for six purposes for active infections, inflammations, or ulcerations in the gastrointestinal tract, from gums to rectum for active infections in the sinuses when used as snuff or sinus wash for active infections in the vagina when used as a douche for active skin infections when used as a powder or wash for active eye infections when used as a wash and as a stimulant/tonic (when used in moderation and for limited duration) in general for mucous membranes throughout the body to help tone them and help them serve their function as one of the first lines of defense against bacterial infection. 

Ceftin is a second-generation broad-spectrum cephalosporin antibiotic used to treat bacterial infections resulting in Lyme s disease, bronchitis, sinusitis, tonsillitis, otitis, skin infections, gonorrhea, and urinary tract infections, and it is considered the antibiotic of choice for otitis media. Ceftin functions by inhibiting bacteria cell wall biosynthesis. 

Preseptal celluHtis is a bacterial infection of the skin and subcutaneous tissue that may proceed into the orbit. Comphcations of infectious disease of the orbit include orbital abscess, epidural or subdural abscess of the neurocranium, purulent meningitis, and thrombosis of the cavernous sinus (Mueller-Forell and Pitz 2004). 

Upper respiratory tract infection (URI) is a term that refers to various upper airway infections, including otitis media, sinusitis, pharyngitis, and rhinitis. Most URIs are viral and often selflimited. Over 1 billion viral URIs occur annually in the United States, resulting in millions of physician office visits each year.1 Excessive antibiotic use for URIs has contributed to the significant development of bacterial resistance. Guidelines have been established to reduce inappropriate antibiotic use for viral URIs.2 This chapter will focus on acute otitis media, sinusitis, and pharyngitis because they are frequently caused by bacteria and require appropriate antibiotic therapy to minimize complications.
