Fungal sinus infection how to diagnose,yeast infection seriousness,can i use greek yogurt for a yeast infection - New On 2016
Author: admin, 13.11.2013When the sinus openings become blocked or too much mucus builds up, bacteria and other germs can grow more easily. Colds and allergies may cause too much mucus to be made or block the opening of the sinuses. A deviated nasal septum, nasal bone spur, or nasal polyps may block the opening of the sinuses.
The symptoms of acute sinusitis in adults usually follow a cold that does not get better or gets worse after 5 - 7 days. Symptoms of chronic sinusitis are the same as those of acute sinusitis, but tend to be milder and last longer than 12 weeks.
Viewing the sinuses through a fiberoptic scope (called nasal endoscopy or rhinoscopy) may help diagnose sinusitis. A green or yellow discharge does not mean that you definitely have a sinus infection or need antibiotics. Eat plenty of fruits and vegetables, which are rich in antioxidants and other chemicals that could boost your immune system and help your body resist infection.

Non-allergic fungal sinusitis: In some instances, mucin and fungus may be identified in patients with sinusitis in the absence of any allergy to fungus. Acute Invasive Fungal Sinusitis: This is the most dangerous and life-threatening form of fungal sinusitis.
Chronic invasive fungal sinus: Unlike acute invasive fungal sinusitis whose typical course is less than 4 weeks (and can actually progress over hours and days), chronic invasive fungal sinusitis is a slower destructive process. Granulomatous invasive fungal sinusitis: This form of fungal sinusitis is rare in the United States. Patients often use the term ‘sinus’ very loosely to refer to a variety of nasal conditions, ranging from simple allergies, various nose ailments to true sinus infections.
Sinusitis is defined as “inflammation and infection of the mucosal lining the nose and paranasal sinuses”.1 As the sinuses and the nose are closely linked, the term “rhinosinusitis” is preferred in the medical literature.
It must be remembered that not all cases of chronic rhinosinusitis (CRS) are due to persistence of an infection.
Traditional bacterial organisms that are implicated in sinusitis include Streptococcus pneumonia, Hemophilus influenza, Moraxella catarrhalis and Staphylococcus aureus. A detailed history, supplemented by comprehensive endoscopic nasal examination, and sometimes, computed tomography (CT) scan of the paranasal sinuses will usually provide an accurate diagnosis. A swab may be taken or the involved sinus aspirated when patients are not responding to medical therapy and to further guide appropriate selection of an antibiotic. Sinus aspiration is the most reliable way to identify the microbial organisms responsible for the infection. Fungal sinusitis may present like chronic rhinosinusitis, or sometimes there are no symptoms at all. Although there is increasing interest in fungal etiologies of CRS, currently there are no guidelines to aid in whether and what antifungal agent to use.
Medical treatment with antibiotics and with systemic and topical steroids attempts to reduce the inflammation and consequent oedema with opening of the natural sinus ostia.
Transnasal maxillary sinus puncture may be indicated in cases resistant to simple medical measures, in cases of sinusitis in immmuno-compromised patients and in patients with severe symptoms, such as headache. Evidence-based care guideline for management of acute bacterial sinusitis in children 1 to 18 years of age.
A licensed medical professional should be consulted for diagnosis and treatment of any and all medical conditions. Most healthy people do not react to the presence of fungus due to a functioning immune system. A complete evaluation by your rhinologist will help to determine if you have a form of fungal sinusitis and how it needs to be treated, as some forms of fungal sinusitis have distinctly different medical and surgical treatments.
This typically occurs around in the middle meatus, an anatomical region on the lateral nasal wall into which most of the major sinuses drain.
Bacterial biofilms consist of bacteria in a specialised protective polysaccharide gel that colonise the nose and the sinuses. However, the diagnosis of chronic rhinosinusitis usually requires a comprehensive endoscopic nasal examination and sometimes a CT scan to highlight the detailed anatomy and localise the pathology. However, the procedure is usually reserved for cases that fail to respond to therapy, or if unusual organisms are suspected. CT scanning is the imaging modality of choice for the paranasal sinuses as it can demonstrate the bony anatomy in detail (Figure 1) and the extent of soft tissue involvement (Figure 6).
The goals of treatment in sinusitis are elimination of bacterial infection, relief of obstruction at the sinus ostia, and normalisation of mucociliary transport function. Saline nasal washes are then given in an attempt to wash out the sinuses through these newly opened ostia.
The procedure can be diagnostic to assess local conditions of the sinus such as ostium patency and the character of the mucus membrane and its secretions. Adult chronic rhinosinusitis: defini- tions, diagnosis, epidemiology, and pathophysiology.

Even when antibiotics do help, they may only slightly reduce the time it takes for the infection to go away. Whether these fungi are innocent bystanders or are the cause of sinus disease is currently under investigation and a subject of great debate. As these cavities occur around the nose, these should be referred to as “paranasal sinuses” so as to differentiate them from other sinuses, and for convenience they are simply referred to as sinuses. Initial obstruction can result from mucosal swelling due to viral infection, allergy, or polyp formation. Another situation when sinus aspiration may be required is when accurate identification of the organisms is required in patients with complicated sinusitis or in patients who are immunocompromised. A plain sinus X-ray is no longer considered satisfactory as it is far inferior to the information obtained from a CT scan. A fungal ball may appear like a foreign body in the nasal cavity or the affected sinus (Figure 7).
For this treatment to be successful, the saline needs to penetrate the sinus ostia and get into the sinuses and wash out the retained secretions. It can also be therapeutic, permitting washout or lavage of the maxillary sinus and instillation of medicines into the sinus cavity. The most commonly involved sinuses are the maxillary and the sphenoid sinuses, where the fungus finds favorable conditions such as warmth and humidity for growth. In addition to obstructing sinus drainage, these conditions can also interfere with mucociliary function, resulting in stasis of secretions and bacterial infection. Scans are usually performed in the coronal plane with successive cuts obtained from the frontal sinus through the sphenoid sinus. Sometimes, bacteria can cause super-added infection in the sinus affected by the fungus ball. Acute rhinosinusitis (ARS) is usually caused by an infection and resolves readily with antibiotics, decongestants and sometimes antihistamines.
The exact etiology of inflammation of CRS is uncertain, but it is well documented that patients with CRS demonstrate the presence of various bacteria within the nose and paranasal sinuses. Typically, only a single sinus is involved, and the disease has a classic appearance on CT or MRI scans. Despite this, some patients develop chronic infection that may persist for weeks or months.
A sensation of nasal obstruction and thick mucoid post-nasal discharge may point towards the diagnosis.
Invasive fungal sinusitis may present with ocular symptoms, hard palate erosion, or neurological symptoms due to intracranial involvement, including headache, altered sensorium, seizures and focal neurological findings.
Underlying medical conditions such as allergic rhinitis, cystic fibrosis, immunodeficiency, ciliary dyskinesis, and chronic inhalation of irritants predispose to the development of chronic sinus disease. There should be a high index of suspicion for fungal sinusitis in immunocompromised patients with these symptoms. This leads to swelling and inflammation that can block the regions where the sinuses normally drain. All of these changes create a favourable environment for bacterial overgrowth and a sinus infection.
Tissue examination under the microscope shows allergic mucin containing fungal elements without tissue invasion.
Treatment involves endoscopic sinus surgery to clear polyps and allergic mucin, and to restore the ventilation and drainage of sinuses.
Anti-fungal treatment is usually not required, as it is the reaction to the fungus that needs to be modulated.
