Allergic Fungal Sinusitis

Sunday, June 10, 2012

The last 2 years, allergic fungal sinusitis (AFS) has become increasingly defined. [1] Historically mistaken for a paranasal sinus tumors, allergic fungal sinusitis (AFS) is now generally, with an immunocompetent host is believed to be an allergic reaction to aerosolized environmental fungi, dematiaceous species. This, such as patients with diabetes mellitus and AIDS affect the immune hosts is in contrast to invasive fungal infections. Allergic fungal sinusitis (AFS), the majority of patients have a history of allergic rhinitis and allergic fungal sinusitis exact timing (AFS), the development can be difficult to distinguish. , As shown below, the thick fungal debris and mucin, sinus allergies no longer available gaps in the drive to be developed and must be removed surgically. After removal of disease recurrence is not uncommon. Anti-inflammatory drug therapy and immunotherapy are employed to prevent recurrence. See the following theimage.Ethmoid bulla in the center of the picture, with the left middle meatus aspiration with thick allergic mucin is the intake at the bottom of the image is at the end. Procedures NextHistoryA few years ago, the nose and paranasal sinuses of invasive fungal disease was represented by a deadly disease. Management followed with topical and systemic antifungal therapy consisted of wide surgical debridement. Early, Aspergillus, a fungus known to cause invasive disease of the sinus, because this culture techniques result in dematiaceous due to the limitations and lack of knowledge of allergic fungal sinusitis (AFS) from patients with paranasal sinus fungus was only paranasal sinus disease. Thus, an aggressive disease were treated.

In 1976, Safirstein that Aspergillus polyposis, crust formation, and sinus cultures, the combination of allergic bronchopulmonary aspergillosis (ABPA), a benign constellation of findings is similar to that observed in allergic process. [2] has been reproduced and expanded explanation Safirstein allergic Aspergillus sinusitis, allergic aspergillosis, paranasal sinuses, and reports. In the late 1980s, a fungal disease process is more widely accepted as a good-natured, and allergic fungal sinusitis (AFS) creates the expansion of the affected sinus cavities because most imaging studies were mixed with a paranasal sinus tumors.In 1989, Robson and his colleagues term this situation may cause a number of different fungi introduced following reports of allergic fungal sinusitis, only Aspergillus. [3] While the disease becomes more known, is related to the diagnosis and treatment of confusion.PreviousNextProblemReconciliation of any allergic fungal sinusitis (AFS) criteria are among the rhinologists. Some authors have made observations.


In 1991, Allphin and colleagues more than the presence of radiographic paranasal sinuses, allergic mucin characteristic histological findings and laboratory evidence of allergy, including concentrate on other forms of fungal sinusitis, distinguish allergic fungal sinusitis (AFS) felt that certain features described. In 1993, Loury, and Schaefer, eosinophilia, immediate skin reactivity of fungal antigens, or serum immunoglobulin G (IgG) antibodies, elevated total immunoglobulin E (IgE) level, such as polyps in the nasal mucosal edema or allergic mucin containing multiple diagnostic criteria for invasive fungal hyphae suggested that histopathological findings and characteristic findings on CT or MR. [4] reporting experience of the Mayo Clinic in 1994, Cody et al diagnostic criteria or a positive fungal cultures collected mucin or non-invasive fungal hyphae in allergic mucin, including not only simplified the characteristic. [5] In 1994, the Bent and Kuhn is probably the most widely accepted criteria for diagnosis are described. Based on analysis of 15 cases, five common characteristics of Gell and Coombs type I (IgE mediated) fungi, nasal polyposis, characteristic radiographic findings, sinus tissue, eosinophilic mucin without fungal invasion of hypersensitivity, including positive and fungal, were observed. [6] In 1997, sinus contents removed during surgery, stains, deShazo radiographic evidence of sinusitis, the presence of allergic mucin (roughly defined as, or histopathology), a positive fungal stain or culture, including a similar set of five criteria, the proposed surgery, the absence of contributing factors ( eg., diabetes mellitus, immune), the sine and the absence of fungal infestation. [7]A positive fungal culture in allergic fungal sinusitis (AFS) does not confirm a diagnosis, nor a negative culture does not exclude. For example, the growth of saprophytic fungi may proliferate diseased sinuses. In addition, the ability to change laboratories mycology and fungal cultures, for example the preparation of a significant proportion of positive effects in the clinical setting. Allergic mucin allergic fungal sinusitis (AFS) is the most reliable indicator. Fungus disease of the sinuses and nasal polyps (AFS), the differential diagnosis is not unique to other mycotic diseases must be defined and the following reasons:Invasive fungal sinusitis: This condition usually have immunity, or in patients with diabetes and is characterized by tissue penetration angioinvasive found in fungi. Hyperesthesia, local pain, nose, and necrosis (an immune person) strongly suggest that invasive fungal sinusitis and allergic fungal sinusitis (AFS) helps to distinguish this disease. Saprophytic fungal growth: The growth of one or more of patients with chronic suppurative paranasal sinusitis can be found in the space. Similar growth in the nose of the patients had an aggressive sinonasal surgery or those with rhinitis sicca may occur in the debris. Fungal cultures may be positive, despite the absence of clinical manifestations of allergic mucin, and invasive fungal sinusitis in the absence of gross and histiologic findings suggest saprophytic fungal growth. Mycetoma, aspergilloma or fungus ball of the sinuses: the clinical presentation of allergic fungal sinusitis (AFS) is different. Rather than involving multiple sinuses, typical of a fungus ball usually a single sinus, sphenoid, maxillary antrum, or contains. Allergic patients is not necessarily affected by this condition and usually do not show nasal polyps. Histological examination of material removed from the sinuses shows fungal hyphae alone without eosinophils. In these patients, surgery is often beneficial. Eosinophilic mucin sinusitis: allergic fungal sinusitis (AFS), it can not be distinguished clinically Pansinusitis, polyps, mucin is characteristic. However, no fungal hyphae examination reveals mucin. Free of fungal sinusitis (APS) is more frequent, such as asthma, allergy, but in this case, a feature is not fixed. Ferguson suggested that this situation may represent a variant of the triple Samter. 

 PreviousNextEpidemiologyFrequencyApproximately 5-10% of patients affected by chronic rhinosinusitis, in fact, allergic fungal sinusitis (AFS) carry a diagnosis. Atopy characteristic of the disease, about two-thirds of the patients reported a history of allergic rhinitis and 90% of one or more antigen-specific IgE levels are elevated. Manning et al, a series of approximately 50% of patients with asthma. No connection has been established aspirin sensitivity.The incidence of allergic fungal sinusitis (AFS), seems to be affected by geographic factors. Review of world literature, allergic fungal sinusitis (AFS) are reported in most temperate regions of the site reveals a relatively high humidity. However, allergic fungal sinusitis (AFS), based on where the incidence of reporting sites have changed significantly. U.S. Allergic fungal sinusitis (AFS), the Mississippi basin, was the most common in the Southeast and Southwest. This geographic difference remains unexplained.Allergic fungal sinusitis (AFS), the most common in adolescents and young adults, average age 21.9 years at diagnosis. Allergic fungal sinusitis, male-female (M / F) ratio (AFS) is slightly different from published reports, but all ages are considered together, is believed to be equal. Published 29 journal articles in the literature 98 cases in the 1980s and early 1990s, equal M / F incidence. University of Texas Southwestern (UT) is also the author of 151 patients and review by colleagues with the ages ranging from 5-75 years, equal M / F ratio was detected. [8]However, M / F ratio in children and adults with age-dependent and may be different. Review of patients at UT Southwestern, children, men (2.1:1 E / F ratio, mean age, 13 y), judges and adults, women (M / F ratio 1:1.4 judges, the average age, 36 y). And other studies, with an average age of the young average age, number of male dominance is more likely to have an evaluation of sex ratios. The mean age of female-dominated series, while the male-dominated series, the average age of 33, 25 and 27, respectively. The only other pediatric series consisted of 10 patients, and 13.6 years, average age of a 1.5:1 E / F ratio had. Interestingly, patient 2 single organization revised series of time when an earlier study, age range 13-51 years (mean age 27.5 years), 1.5:1 to an E / N ratio, and then analysis was 13-69 years (mean age not given) with an age range, a 1:1.4 E / F ratio had.PreviousNextEtiologyMost rhinologists allergic fungal sinusitis (AFS), fungal spores, allergic mucin and nasal cavity and paranasal sinuses of the nose where polyposes mushrooms, believe it is an allergic reaction. Allergic fungal sinusitis (AFS), the causative fungus is usually due to Aspergillus allergic fungal sinusitis (AFS) with a small component of the genera Bipolaris, Curvularia, Exserohilum, Alternaria, Drechslera, Helminthosporium, and Fusarium are dematiaceous formed. Manning, a 1996 review conducted by the British literature, allergic fungal sinusitis (AFS), 263 cases, 168 cases had positive fungal cultures, which have been identified. Aspergillus 168, this has only 13% positive cultures, 87%, was dematiaceous genus.To date, the largest single-center experience reported to UT Southwestern Medical Center in Dallas, Texas is located. PNS writer and his colleagues obtained in this evaluation by the fungus Bipolaris, Curvularia, then, the following Table 1, with an incidence similar in adults and children, showed that the most common pathogen is present. Most commented, the most common fungus Bipolaris and Curvularia species, indicating that the recovered agree.Geographic location, particularly examined, further to the west and the inner series, Bipolaris species are more likely to be dominated by fungi recovered. When the Southeast Series, Curvularia species recovered was higher. Interestingly, the UT Southwestern experience, 13% of adults but no children rescued from Aspergillus. A report from India who not only rescued Aspergillus fungi in allergic fungal sinusitis (AFS) detection have found in all 11 patients.Table 1: Active fungal UT Southwestern Medical Center (Open in a new window Table) at the designatedFungusChildren (n = 44), adult (n = 107) Bipolaris21 (66%, 21/32) 40 (57%, 40/70) Curvularia7 (22%, 7/32) 12 (17%, 12/70) Exserohilum22Alternaria13Aspergillus ( Niger / flavus) 09 (13%) Acremonium01Chrysosporium01Helminthosporium01No Growth221No Bipolaris/Curvularia1 Data1216Combination1 Aspergillus / AcremoniumControversy exists on whether the disease was infectious or allergic. Manning and Holman objective of this discussion was addressed by two separate studies. [9] In the first study, culture-positive Bipolaris allergic fungal sinusitis (AFS), 8 patients were prospectively allergic fungal sinusitis (AFS) compared with control groups that do not have 10. Both groups (1) radioallergosorbent test (RAST) and enzyme-linked immunosorbent assay (ELISA) for the inhibition to Bipolaris-specific IgE and IgG antibodies, and Bipolaris antigen (2) skin test. All 8 patients had positive RAST and Bipolaris Bipolaris antigen-specific IgE and IgG ELISA inhibition reactions had positive skin test for. 10 in the control group of eight allergic fungal sinusitis (AFS) in the pathophysiology of the antigen (both in vivo and in vitro), implicating the importance of allergy, skin and serologic tests were negative consequences as well.A complementary study, allergic fungal sinusitis (AFS) of 14 patients with allergic fungal sinusitis, sinus mucosal samples (AFS) compared with control groups that do not have 10. Eosinophilic mediators (major basic protein and eosinophil-derived neurotoxin) and neutrophil derived mediators (neutrophil elastase) were performed to evaluate the immunohistochemical analysis of the key features of inflammation. Induced eosinophilic mediators (P is much more commonAllergic fungal sinusitis (AFS) associated with the concept of eosinophilic activation in allergic fungal sinusitis (AFS) and mucin eosinophil cationic protein levels in serum of patients studied was stressed by Feger et al. No differences in serum eosinophil cationic protein in allergic fungal sinusitis (AFS) and the control group of patients are detected, but levels of eosinophilic cationic protein in allergic fungal sinusitis (AFS) mucins were significantly higher in patients, PStudies such as Manning et al and al Feger strong immunologic and allergic fungal sinusitis (AFS) is a highly contagious fungal diseases than a point on the spectrum of immunological disorders histological data to support the argument that the offer represented. [10]PreviousNextPathophysiologyToday, allergic fungal sinusitis (AFS) in the pathophysiology of allergic bronchopulmonary fungal disease (a term instead of bronchopulmonary aspergillosis) is considered to be similar. Manning and his colleagues, and events in several related factors in allergic fungal sinusitis (AFS) have suggested that the development and monochrome. First, it provides atopic main antigenic stimulus by the normal nasal respiration theoretical, fungi is exposed. Cause tissue edema after an initial inflammatory response is a Gell and Coombs type I (IgE mediated) and type III (immune complexâ?-Mediated) reaction develops as a result of both. Such septal deviation or turbinate hypertrophy, stasis within the sinuses as a result, may be accentuated by anatomic factors, obstruction of the sinus ostium. For this reason, the landlord is allergic increasing antigenic exposure, creates an ideal environment for yeast proliferation even more.A point, the loop may elect to self-this process, the final product, allergic mucin, fungal sinusitis, allergic (APS) is held in patients with sinus to fill the resulting material becomes. This accumulation of debris, and the process of blocking the spread of the involved sinuses.The allergic mucin, and ultimately, clinical, histological and radiological features, the production of allergic fungal sinusitis (AFS) is private and serves as a hallmark of the disease. Grossly, allergic fungal mucin, a thick strong and highly viscous. The color is light brown, brown or dark green as depicted in the following figures, subject to change. Speaking of allergic fungal mucin, peanut butter and axle grease, such as its characteristic gross appearance resulted in the use of descriptive terms.Ethmoid bulla in the center of the picture, with the left middle meatus aspiration with thick allergic mucin is the intake at the bottom of the image is at the end. Viscosity of a thick allergic mucin in a patient with allergic fungal sinusitis is being drawn from the nasal cavity and the vestibule. PreviousNextPresentationNasal congestion, allergic rhinitis, or nasal congestion, runny nose, inflamed, with symptoms of chronic sinusitis with nasal drainage and headaches normally found in allergic fungal sinusitis (AFS) in patients with. Generally, allergic fungal sinusitis (AFS), the presentation is subtle. Patients typically, on investigation, the gross description of allergic fungal mucin gradually match the semi-solid nasal crusts and production complaining of nasal obstruction. Development unaware of the existence of the patient's own nasal congestion, can be slow, so slow. If you have facial dysmorphia, because of allergic fungal sinusitis (AFS), a slow progression, so that its progression is usually slow, unrecognized by the patient and family members. Pain Allergic fungal sinusitis (AFS) with bacterial rhinosinusitis in patients with rare and suggest the presence of.Allergic fungal sinusitis (AFS) Patients who are atopic, but the symptoms are usually antihistamines, intranasal corticosteroids, and were previously unresponsive to immunotherapy. The use of systemic corticosteroids, can produce some relief of symptoms, recurrence after completion of therapy, but are typical. In patients with invasive fungal sinusitis, unlike in patients with allergic fungal sinusitis (AFS) are always immunity.

Gross facial disfigurement and orbital examination, physical findings, and ocular abnormalities in range of 1 following image portrayed from nasal congestion caused by intranasal inflammation and polyposis, usually broad. , The Author and his colleagues proptosis, facial dysmorphism, the 2nd image depicting said telecanthus, and flattening inflammation, more commonly a series of 151 patients (42% vs 10%) than that of adults and children 17 years of age was 18 years old or older and children under the age of 44 to 107, including adults, the following Table shown in figure 2.Only the anterior nasal cavity and extending into the vestibule showing widespread polyposis View inside the nasal vestibule, septum on the right side and right lateral vestibular wall (nasal ala) on the left side. All located in the center of the polyps. Polyps in the nasal vestibule virtually hang out. Allergic fungal flattening of the right proptosis, telecanthus and malar A 15-year-old boy with sinusitis cause their eyes are asymmetrical position is pushed inferiorly by the left and right side of his nasal ala. Spheres, showing the asymmetric positioning of the eyes and telecanthus and 9-year-old girl with allergic fungal sinusitis.In general, patients in this study proptosis is present, the flattened sidewall proptosis telecanthus and a display depending on the amount described above, can be determined. Development is often occurred over long periods of proptosis, diplopia or loss of vision is usually not seen.However, when the adjacent anatomic spaces allergic fungal sinusitis (AFS) as an extension of the clinical course is dramatic, such as vision loss, can produce. She encountered in 3 of 82 patients identified by the ophthalmic nerve compression caused by Marple and colleagues allergic fungal sinusitis (AFS), a fungus disease in Visual loss was reversible with immediate surgical removal. [11] Return weeks occurred in the month.

Fungus inciting antigen for immunotherapy to be successful should be removed. Any recurrent disease should be removed surgically.Anatomy PreviousNextRelevantAnatomy of the surgical procedure is the same as for any ESS. Usually, anatomy, because the expansion of the sinuses is impaired secondary to the disease process. The lateral nasal wall, obliterating the nasal cavity on the affected side, is pushed medially and below 1 As shown in the lower and middle turbinates, the two images, is pushed inferomedially. If included in the ethmoid sinuses, the roof is usually extended superiorly into the anterior cranial fossa and the lateral wall, as shown in the following final orbit expanded.Spheres, showing the asymmetric positioning of the eyes and telecanthus and 9-year-old girl with allergic fungal sinusitis. Coronal CT of the sinuses with the expansion of the right orbit and right on the mucocele into the right-hand side shows the intense allergic fungal sinusitis. Expansion of the lower extension of the middle turbinate with the ethmoid complex and more in a patient with allergic fungal sinusitis is a typical view of the middle meatus.
