Abstract
OBJECTIVE This study aimed to investigate the clinical characteristics of sphenoid sinus fungus ball (SSFB) to help increase the accuracy of diagnosis and efficiency of treatment. METHODS We retrospectively analyzed the data of 77 patients who were histopathologically diagnosed with SSFB. RESULTS The mean age of SSFB patients was 52.4 years (range 25-84), and 47 patients (61.0%) were female. Compared to age-matched and sex-matched chronic rhinosinusitis (CRS) patients, headache was more common in SSFB patients (79.2%; p < 0.0001). SSFB patients also had higher prevalence of diabetes than CRS (p = 0.0420). The features of computed tomography (CT) were sphenoid sinus opacification (100%), sclerosis (93.5%), calcification (76.6%), and bone erosion (41.6%). Functional endoscopic sinus surgery (FESS) was the best treatment option, and the trans-ethmoid (n = 64, 83.1%) was the most commonly used approach. No one experienced a recurrence of SSFB in 44 successfully contacted patients. Six months after FESS, 91.0% of patients (40/44) established proper drainage in the sphenoid sinus. The recovery rates for headache and nasal symptoms were 91.7% (33/36) and 77.8% (7/9) respectively. CONCLUSION SSFB is more prevalent in older women and usually presents as unilateral headache. Diabetes is a potential risk factor for SSFB. CT findings provide evidence for diagnosis and suggestions for surgical approaches. FESS is the optimal treatment for SSFB. After FESS, most patients had good prognosis with no recurrence of SSFB. However, regular endoscopic follow-up is required due to the possibility of the postoperative closure of sphenoid ostium. LEVEL OF EVIDENCE 3 Laryngoscope, 133:3292-3298, 2023.

Abstract
The incidence of allergic diseases worldwide is rapidly increasing, making allergies a modern pandemic. This article intends to review published reports addressing the role of fungi as causative agents in the development of various overreactivity-related diseases, mainly affecting the respiratory tract. After presenting the basic information on the mechanisms of allergic reactions, we describe the impact of fungal allergens on the development of the allergic diseases. Human activity and climate change have an impact on the spread of fungi and their plant hosts. Particular attention should be paid to microfungi, i.e., plant parasites that may be an underestimated source of new allergens.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is an inflammatory disorder of the nose and sinuses. Since fungi were postulated as a potential cause of CRS in the late 1990s, there has been increasing controversy about the use of both topical and systemic antifungal agents in its management. Although interaction between the immune system and fungus has been demonstrated in CRS, this does not necessarily imply that fungi are the cause of CRS or that antifungals will be effective its management. OBJECTIVES To assess the effectiveness of topical or systemic antifungal therapy in the treatment of CRS. SEARCH METHODS We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the most recent search was 8 March 2011. SELECTION CRITERIA All randomised, placebo-controlled trials considering the use of topical or systemic antifungal therapy in the treatment of CRS and allergic fungal sinusitis (AFS). CRS was defined using either the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) or American Academy of Otolaryngology - Head and Neck Surgery (AAO-HNS) criteria. DATA COLLECTION AND ANALYSIS We reviewed the titles and abstracts of all studies obtained from the searches and selected trials that met the eligibility criteria. We extracted data using a pre-determined data extraction form. There was significant heterogeneity of outcome data reporting with reports containing both parametric and non-parametric representations of data for the same outcomes. Means and standard deviations for change data were unavailable for a number of trials. Due to the limited reported data, we contacted authors and used original data for data analysis. MAIN RESULTS Six studies were included (380 participants). Five studies investigated topical antifungals and one study investigated systemic antifungals. The risk of bias in all included studies was low, with all trials being double-blinded and randomised. Pooled meta-analysis showed no statistically significant benefit of topical or systemic antifungals over placebo for any outcome. Symptom scores in fact statistically favoured the placebo group. Adverse event reporting was statistically significantly higher in the antifungal group. AUTHORS' CONCLUSIONS On the basis of this meta-analysis, there is no evidence to support the use of either topical or systemic antifungal treatment in the management of CRS.

Abstract
Fungal sinusitis is divided into two categories depending on mucosal invasion by fungus, i.e., invasive and noninvasive. Invasive fungal sinusitis is further divided into acute and chronic disease based on time course. Noninvasive fungal sinusitis includes chronic noninvasive sinusitis (fungal ball type) and allergic fungal sinusitis. Chronic noninvasive sinusitis is the most predominant fungal sinusitis in Japan, followed by allergic fungal sinusitis. Invasive fungal sinusitis is rare. Hyphal tissue invasion is seen in invasive fungal sinusitis. Acute invasive fungal sinusitis demonstrates hyphal vascular invasion while chronic invasive fungal sinusitis usually does not. Fungal tissue invasion is never found in noninvasive sinusitis. A fungal ball may exist adjacent to sinus mucosa, but its hyphae never invade the mucosa. Fungal balls sometimes contain conidial heads and calcium oxalate, which aid in identifying the fungus in the tissue. Allergic fungal sinusitis is characterized by allergic mucin that is admixed with numerous eosinophils and sparsely scattered fungal elements. Histopathology is important in classifying fungal sinusitis, especially in confirming tissue invasion by the fungus.

Abstract
Background This study was designed to assess the relative efficiency of three different culture media for isolating fungi in patients suspected of having noninvasive fungal sinusitis. Methods A prospective study was performed of 209 operative samples of sinus “fungal-like” mucin from 134 patients on 171 occasions and processed for microscopy and fungal culture in Sabouraud's dextrose agar, potato dextrose agar, and broth media. Results Ninety-three (69%) of 134 patients had evidence of fungal infection. Two-thirds of patients had negative microscopy samples yet 56% of these went on to positive cultures. Forty-five percent cultured Aspergillus genus. Discrepancy between the fungi cultured in different media and on different occasions was common. With a single culture medium up to 19% of patients and 15% of samples would have been falsely labeled fungal negative. Conclusion Increasing the number and type of fungal culture media used increases the number and range of fungal isolates from mucin in patients with the features of fungal sinusitis. Negative specimen microscopy is unreliable. All specimens should be cultured in multiple media and on multiple occasions when fungal sinusitis is suspected.

Abstract
Background Ever since its characterization in the 1970s, allergic fungal rhinosinusitis (AFRS) has been the subject of much controversy, especially regarding its pathogenesis. In this study, we analyzed the differential expression of genes that encode protease-activated receptors (PAR) in patients with AFRS and patients with chronic rhinosinusitis, and tried to understand the pathogenic basis of this disease. Objective To analyze the differential expression of PAR genes in patients with AFRS and in patients with chronic rhinosinusitis. Methods Mucosa from ethmoid sinuses of 51 patients (tests and controls) was biopsied and evaluated for messenger RNA expression of PAR genes by using reverse transcriptase–polymerase chain reaction. Each of the four PAR genes, i.e., par1, par2, par3 and par4 was amplified, the final gene products were run on 1.8% agarose gel and analyzed by densitometry to calculate differential expression. The significance level was determined as p ≤ 0.05. Results It was observed that the expressions of all four par genes were higher in the test samples compared with the controls, but statistical significance was achieved only for par1 (p=0.004) and par2 (p=0.05). Comparative expression of the four PAR genes was also performed within the test and control groups, and a statistically significant difference was seen between par1 and par2 (p=0.007), par1 and par3 (p=0.029), par1 and par4 (p=0.0001), par2 and par4 (p=0.002), and par3 and par4 (p=0.009) in the test group. In the control group as well, par1, par2, and par3 exhibited a higher expression compared with par4 but the difference was significant between par3 and par4 genes only. Conclusion Patients with AFRS expressed increased levels of PAR genes in their nasal mucosa, and, of the four PAR genes, a higher expression of par1, par2, and par3 was observed in both the groups compared with par4. This information contributes toward our understanding of pathogenesis and possibly treatment of AFRS.

Abstract
Background It has been postulated that fungal organisms might represent the immunologic target initiating and maintaining the disease process in patients with chronic rhinosinusitis (CRS). The presence of fungi in nasal mucus has been established by different groups, but so far it has not been shown how the immune system could even recognize such extramucosal—extracorporal—fungal targets. The aim of this study was to determine whether fungal DNA is present in tissue specimens taken from patients with polypoid CRS. Methods Twenty-seven surgical specimens were collected from patients suffering from CRS. Fifteen surgical specimens from healthy ethmoidal mucosa served as controls. A second set of controls consisted of five surgical specimens of acoustic neuroma, which were included to rule out contamination within the protocol. All paranasal tissue samples were treated and rinsed carefully with a solution of Dithiothreitol to digest any nasal mucus and ensure that only tissue was examined. A highly sensitive two-step polymerase chain reaction (PCR) was applied to detect fungal DNA, using one universal primer for unspecific detection of fungal DNA and a second primer pair specific for Alternaria. Results Fungal DNA was detected in all 27 CRS specimens equally with both PCR primers. Controls from healthy paranasal mucosa were positive using the panfungal primers in 10 of 15 cases but were all negative for Alternaria DNA. PCR was negative for fungal DNA in all five neuroma specimens. Conclusions Fungal DNA can be detected within sinonasal tissue specimens of patients suffering from CRS. These findings need to be discussed with respect to the proposed hypothesis of the immune system recognizing extramucosal organisms and initiating an immune response in sensitized patients.

Abstract
OBJECTIVE To review the topic of fungal raw materials used for the production of allergen extracts and the associated challenges and highlight candidate areas for development before standardized fungal allergen extracts can be commercially produced. DATA SOURCES A PubMed search was performed using focused keywords and combined with a review of regulatory documents and industry guidelines. Several books on mycology also were consulted. STUDY SELECTIONS The information obtained through the literature, books, and industry was scrutinized and combined with personal experience and expertise to write this article. RESULTS Fungi are complex ubiquitous organisms on Earth. They are beneficial and detrimental for humans. Fungi can cause hypersensitivity reactions, including types I, III, and IV. The procurement of fungal raw materials to prepare allergen extracts for diagnosis and possible allergen immunotherapy is complex owing to the intrinsic nature of fungi and their complex genome. Allergen manufacturers produce allergen extracts with variable qualitative and quantitative compositions, which can lead to unpredictable clinical outcomes. CONCLUSION The clinician should be aware of the factors responsible for the qualitative and quantitative compositions of fungal allergen extracts and the reasons that currently preclude their standardization. Scientific advances and collaboration and cooperation between allergen manufacturing companies and regulatory agencies are necessary to improve the quality and consistency of fungal extracts. Moreover, clinicians should understand the limitations of currently available fungal extracts.

Abstract
Chronic rhinosinusitis (CRS) is a multifactorial disease. Predisposing factors can be divided into environmental and non-host factors, such as pollution, viral infections, smoking, fungus, and bacteria; general host factors, including genetic factors and immune deficiency; and local host factors, including persistent focal inflammation within the ostiomeatal complex. Evidence suggests that the underlying bone in the ostiomeatal complex is actively involved in the disease process of CRS. The evidence concerning a broad range of predisposing factors for CRS is reviewed. Chronic rhinosinusitis is an inflammatory disorder with numerous predisposing factors, including genetics, pollution, anatomic anomalies, bacteria, and fungus. In some studies, fungi have been cultured from nearly 100% of patients with rhinosinusitis and nasal polyposis. T-cell sensitization to fungus with production of the T-helper 2 (Th2) cytokine interleukin-5 has been proposed as a key step in the initiation of the disease. Interleukin-5 also plays an important role in the effector phase of the disease through its effects on eosinophilopoesis and eosinophil survival. There is considerable controversy concerning the role of fungi as the cause of “chronic eosinophilic rhinosinusitis” and whether this even represents a distinct clinical entity. Further study is also required to define the optimal treatment for the disease.

Abstract
INTRODUCTION Histoplasma capsulatum is rarely found in nose and sinuses in immunocompetent and even in immunosupressed patients. A literature review revealed rare cases of H. capsulatum sinusitis and the case we describe in this paper is the first case of H. capsulatum sinusitis in Morocco. The purpose of our work is to present a rare case of H. capsulatum sinusitis and a literature review. CASE REPORT A male patient, at his 39 presented to the emergency with suffered from nasal congestion and yellow postnasal rhinorrhea, occasional headaches and epistaxis for over than two months. He had human immunodeficiency virus (HIV) infection for 6 years with failing treatment adherence and he had an opportunistic infection and unconfirmed pulmonary tuberculosis treated 3 years ago. Computerized tomography from paranasal sinus revealed complete opacification of the ethmoid-maxillary sinuses in the right fossa, consistent with acute sinusitis. The cultures of the sinus aspirate, skin biopsy, were positive for H. capsulatum and the histology of the nasal mucosa and skin biopsy specimen of the rash evoking a sinusitis and cutaneous histoplasmosis. The patient was started a treatment with intravenous amphotericin B at a rate of 1 mg/kg/day with clear clinical and biological improvement. DISCUSSION Cultures and histopathologic study confirm histoplasmosis. Itraconazole and amphotericin B are the first line drugs. CONCLUSION Patients with progressive disseminated histoplasmosis and those with AIDS should be treated with amphotericin B, and the ENT should suspect of opportunistic agents in immunosupressed patients with sinusitis.

Abstract
BACKGROUND This paper describes our experience in the management of acute and chronic invasive fungal rhinosinusitis (IFRS) in adults. METHODS Medical files of all patients aged >18 years treated in our institutions for IFRS from 2002 to 2013 were retrospectively reviewed. RESULTS A total of 18 cases (10 acute and 8 chronic) were recorded. In acute form, haematological malignancies represented the principal comorbidity (100%), while in chronic form this was diabetes mellitus (87.5%). All patients received systemic antifungal agents. Endoscopic sinus surgery was performed in 16/18 patients (88.9%). Among patients with an acute IFRS, 4/10 died of fungal infection (40%), on the other side 2/8 patients with chronic IFRS died of the evolution of the mycosis (25%). CONCLUSIONS Acute and chronic IFRS are different entities: in acute form, prognosis is poor, so therapy should be promptly performed, although host immune status and evolution of the haematological disease are key factors for the outcome. In chronic form, a wide surgical excision of the disease is recommended in order to obtain a complete removal of fungal infection. In both forms, early clinical findings are non-specific and ambiguous, so diagnosis depends on a high index of suspicion, taking into account predisposing factors.

Abstract
OBJECTIVE To study and characterize the features of AFRS in children as compared to adults. METHODS 50 consecutive patients of AFRS attending our outpatient department were included in the study from July 2011 to December 2013. They were divided into two groups (A and B) according to age being ≤14 years and >14 years. Clinical history and examination included anterior rhinoscopy, SNOT 20 scores, CT of Nose and PNS (para nasal sinuses) (Lund Mackay scores), diagnostic nasal endoscopy (Kupferberg's grades), punch biopsy from nasal polyp, serum IgE, absolute eosinophil counts (AEC) and Aspergillus skin hypersensitivity test was done in all patients for conformation of AFRS. Bent and Kuhn's criteria were used for diagnosis. Sweat chloride levels were done in all patients of group A. RESULTS Group A had 12 patients and group B had 38. Mean duration of symptoms was significantly less in children as compared to adults (p<0.05). All patients of both groups had nasal polyposis at presentation. Unilateral disease and multisinus involvement was more common in children (6/12) as compared to adults. Proptosis (2/12) and telecanthus (4/12) was more common in children (group A) as compared to adults (group B). LM (Lund Mackay) scores and serum IgE were significantly high in children as compared to adults. Follow up CT scans showed early evidence of recurrence in children as compared to adults (p<0.05). CONCLUSION AFRS was seen to be more aggressive in children with increased fungal load when compared with adults. Typically, AFRS in children was less responsive to treatment with increased recurrence rates.

Abstract
BACKGROUND Mold pathogens are a leading cause of chronic rhinosinusitis. Successful isolation of mold on culture is helpful in establishing a diagnosis and guiding therapy. Though mucolytic agents are commonly used in European countries, they are not part of everyday use in North America. In this case-control prospective study, we investigated the yield of fungal culture before and after treatment of sinus aspirates with the mucolytic agent dithiothreitol in a United States hospital. METHODS Over a 5-month period during 2011-2012, 359 sinus aspirates from 294 patients with symptoms suspicious for chronic sinusitis or allergic fungal sinusitis were collected. Aspirates were cultured on fungal medium before and after treatment with dithiothreitol. RESULTS Of the 359 pairs of cultures, 62 (17.3%) demonstrated mold growth on at least 1 of the plates, 9 (14.5%) of which grew more than 1 species of mold. A total of 75 molds were identified, 41 (54.7%) of which were successfully cultured only when the mucus was pretreated with dithiothreitol (p < 0.0001). Quantitatively, more colonies grew from dithiothreitol-treated mucus than from direct-inoculation (p < 0.0001). CONCLUSION This study confirms improved recovery of mold from sinus cultures after pretreatment of samples with dithiothreitol. Further studies are needed to correlate these findings with clinical outcome.

Abstract
Allergic fungal sinusitis (AFS), also referred to as allergic fungal rhinosinusitis (AFRS), is a noninvasive, eosinophilic form of recurrent chronic allergic hypertrophic rhinosinusitis. AFS has distinct clinical, histopathological, and prognostic findings that differentiate it from other forms of sinusitis. The core pathogenesis and optimum treatment strategies remain debated. Concerns surround the use of immunotherapy for AFS because allergen-specific immunoglobulin G (IgG) induced by immunotherapy could theoretically incite a Gell and Coombs type III (complex mediated) reaction. Type I hypersensitivity is established by high serum levels of allergen-specific IgE to various fungal antigens and positive Bipolaris skin test results. Type III hypersensitivity is established by an IgG-mediated process defined by the presence of allergen-specific IgG that forms complexes with fungal antigen inducing an immunologic inflammatory response. These reveal the multiple immunologic pathways through which AFS can impact host responses. Recent literature establishing benefits of fungal immunotherapy and no evidence of type III–mediated reactions, severe local reactions, or delayed reactions, indicate that application of AFS desensitization is a reasonable therapeutic strategy for this difficult to manage entity. Our review should encourage further clinical acceptance of AFS desensitization because the existing literature on this subject shows benefits of fungal immunotherapy and no evidence of type III–mediated reactions, severe local reactions, or delayed reactions.

Abstract
Fungal rhinosinusitis is being recognized and reported with increasing frequency over the last two decades worldwide. Intracranial extension is the most dreaded complication of fungal sinusitis with high mortality rates. We report a case of chronic rhinosinusitis in a 55-year-old diabetic male, caused by Fusarium species. The patient was diagnosed as a case of chronic left maxillary sinusitis with cavernous sinus thrombosis. The sinus lavage showed fungal elements on direct microscopic examination and culture revealed growth of Fusarium species within 4 days of incubation. Conservative therapy with IV amphotericin B resulted in favorable outcome of the patient. This is an extremely rare case where cavernous sinus thrombosis occurred as a complication secondary to Fusarium species rhinosinusitis.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is an inflammatory disorder of the nose and sinuses. Because fungi were postulated as a potential cause of CRS in the late 1990s, contrasting articles have advocated and refuted the use of antifungal agents in its management. Although good research shows an interaction of the immune system with fungus in CRS, e.g., allergic fungal sinusitis (AFS), this does not imply that fungi are the cause of CRS or that antifungals will be effective in management. This study was designed to assess the potential advantage of either topical or systemic antifungal therapy in the symptomatic treatment of CRS to aid physicians in making informed decisions about treating patients with CRS. METHODS A systematic review of the literature was performed with meta-analysis. All studies obtained from searches were reviewed and trials meeting the eligibility criteria were selected. CRS was defined using either the European Position Paper on Rhinosinusitis and Nasal Polyps or American Academy of Otolaryngology-Head and Neck Surgery criteria. Authors were contacted and original data were used for data analysis. RESULTS Five studies investigating topical antifungals and one investigating systemic antifungals met the inclusion criteria. All trials were double blinded and randomized. Pooled meta-analysis showed no statistically significant benefit of topical or systemic antifungals over placebo. Symptoms scores statistically favored the placebo group for this outcome. Adverse event reporting was higher in the antifungal group. CONCLUSION Reported side-effects of antifungal therapies may outweigh any potential benefits of treatment based on this meta-analysis and the authors therefore do not advocate the use antifungal treatment in the management of CRS.

Abstract
ABSTRACT
Allergic fungal rhinosinusitis (AFRS) has always remained a topic of discussion at all rhinology meets. Despite so much of literature available, the nature of this disease, its diagnosis, pathogenesis, classification and appropriate management continue to generate debate and controversy even after three decades of research and investigation. AFRS is an endemic disease in North and South India. In spite of this, there has been no optimal management protocol for this disease being followed in India yet. To overcome this, a national panel was conducted on AFRS at the ENT Surgical Update 2011, held at Postgraduate Institute of Medical Education and Research, Chandigarh with experts from all over the country so that a consensus can be achieved regarding the workup and management of AFRS.

Abstract
Allergic Aspergillus sinusitis (AAS) is a three decade old clinicopathologic entity in which mucoid impaction akin to that of allergic bronchopulmonary aspergillosis (ABPA) occurs in the paranasal sinuses. Features such as radiographic evidence of pansinusitis, passage of nasal plugs and recurrent nasal polyposis in patients with an atopic background is suggestive of AAS. Histopathlogic confirmation from the inspissated mucus is a sine qua non for the diagnosis. Heterogeneous densities on computed tomography of the paranasal sinuses are caused by the 'allergic mucin' in the sinuses. Many patients give a history of having undergone multiple surgical procedures for symptomatic relief. The current approach to treatment appears to include an initial surgical debridement followed by postoperative oral corticosteroids for long durations. Although both ABPA and AAS are classified as Aspergillus-related hypersensitivity respiratory disorders, their co-occurrence appears to be an infrequently recognised phenomenon. This could perhaps be attributed to the fact that these two diseases are often treated by two different specialties. A high index of suspicion is required to establish the diagnoses of ABPA and AAS. All patients with asthma and/or rhinosinusitis along with sensitisation to Aspergillus antigens are at an increased risk of developing ABPA and/or AAS. ABPA must be excluded in all patients with AAS and vice versa. Early diagnosis and initiation of appropriate therapy could plausibly alter the course of the disease processes and prevent the possible development of long term sequelae.

Abstract
BACKGROUND It is important to differentiate sinonasal fungus ball from non-fungal sinusitis and other forms of fungal sinusitis in order to determine the optimal treatment. In particular, a sinonasal fungus ball, a non-invasive fungal sinusitis, can be characterized by radiologic findings before surgery. PURPOSE To differentiate a sinonasal fungus ball from other types of sinusitis and determine optimal treatment on the basis of radiologic findings before surgery. MATERIAL AND METHODS We studied 119 patients with clinically and pathologically proven sinonasal fungus balls. Their condition was evaluated radiologically with contrast-enhanced CT (99 patients), non-contrast CT (18 patients) and/or MRI (17 patients) prior to sinonasal surgery. RESULTS Calcifications were found in 78 of 116 (67.2%) patients who underwent CT scans for fungus ball. As opposed to non-contrast CT scans, contrast CT scans revealed hyperattenuating fungal ball in 82.8% and enhanced inflamed mucosa in 65.5% of the patients, respectively. On MRI, most sinonasal fungal balls showed iso- or hypointensity on T1-weighted images and marked hypointensity on T2-weighted images. Inflamed mucosal membranes were noted and appeared as hypointense on T1-weighted images (64.7%) and hyperintense on T2-weighted images (88.2%). CONCLUSION When there are no calcifications visible on the CT scan, a hyperattenuating fungal ball located in the central area of the sinus with mucosal thickening on enhanced CT scans is an important feature of a non-invasive sinonasal fungus ball. On MRI, a sinonasal fungus ball has typical features of a marked hypointense fungus ball with a hyperintense mucosal membrane in T2-weighted images. A contrast-enhanced CT scan or MRI provides sufficient information for the preoperative differentiation of a sinonasal fungus ball from other forms of sinusitis.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is an inflammatory disorder of the nose and sinuses. Since fungi were postulated as a potential cause of CRS in the late 1990s, there has been increasing controversy about the use of both topical and systemic antifungal agents in its management. Although interaction between the immune system and fungus has been demonstrated in CRS, this does not necessarily imply that fungi are the cause of CRS or that antifungals will be effective its management. OBJECTIVES To assess the effectiveness of topical or systemic antifungal therapy in the treatment of CRS. SEARCH STRATEGY We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the most recent search was 8 March 2011. SELECTION CRITERIA All randomised, placebo-controlled trials considering the use of topical or systemic antifungal therapy in the treatment of CRS and allergic fungal sinusitis (AFS). CRS was defined using either the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) or American Academy of Otolaryngology - Head and Neck Surgery (AAO-HNS) criteria. DATA COLLECTION AND ANALYSIS We reviewed the titles and abstracts of all studies obtained from the searches and selected trials that met the eligibility criteria. We extracted data using a pre-determined data extraction form. There was significant heterogeneity of outcome data reporting with reports containing both parametric and non-parametric representations of data for the same outcomes. Means and standard deviations for change data were unavailable for a number of trials. Due to the limited reported data, we contacted authors and used original data for data analysis. MAIN RESULTS Six studies were included (380 participants). Five studies investigated topical antifungals and one study investigated systemic antifungals. The risk of bias in all included studies was low, with all trials being double-blinded and randomised. Pooled meta-analysis showed no statistically significant benefit of topical or systemic antifungals over placebo for any outcome. Symptom scores in fact statistically favoured the placebo group. Adverse event reporting was statistically significantly higher in the antifungal group. AUTHORS' CONCLUSIONS On the basis of this meta-analysis, there is no evidence to support the use of either topical or systemic antifungal treatment in the management of CRS.

Abstract
Acute fungal sinusitis is a life-threatening infection affecting immunocompromised patients. Historically, the most commonly recovered fungi are Aspergillus and Mucor. The extent of potentially disfiguring debridement surgery is grossly determined by the appearance of bleeding at the margins, signifying viable tissue and the absence of fungus. Requests for frozen section may concern the initial diagnosis and the intraoperative verification of margin status. In 12 patients with acute fungal sinusitis, frozen section was used in 8. Routine H&E stains demonstrated fungal hyphae in necrotic debris in 5 cases, often associated with vascular and perineural invasion. All patients underwent extensive sinus debridement, including orbital exenteration in 2 cases. All 12 patients died, 9 of fungal sepsis. Autopsy in 3 patients showed pulmonary involvement (2 cases), intracranial spread (1 case), and no residual fungus (1 case). Inexperience with organism recognition is surmountable. Frozen section has a role in the management of this devastating disease.

Abstract
Despite the advantages of providing an early presumptive diagnosis, fungal classification by histopathology can be difficult and may lead to diagnostic error. To assess the accuracy of histologic diagnosis of fungal infections vs culture ("gold standard"), we performed a 10-year retrospective review at our institution. Of the 47 of 338 positive mold and yeast cultures with concurrent surgical pathology evaluation without known history of a fungal infection, 37 (79%) were correctly identified based on morphologic features in histologic and/or cytologic specimens. The 10 discrepant diagnoses (21%) included misidentification of septate and nonseptate hyphal organisms and yeast forms. Errors resulted from morphologic mimics, use of inappropriate terminology, and incomplete knowledge in mycology. The accuracy did not correlate with preceding antifungal therapy (P = .14) or use of special stains (P = .34) and was not operator-dependent. Among 8 discrepancies with clinical follow-up available, 2 potential adverse clinical consequences resulted. While histopathologic identification of fungi in tissue sections and cytologic preparations is prone to error, implementation of a standardized reporting format should improve diagnostic accuracy and prevent adverse outcomes.

Abstract
Allergic fungal sinusitis is a non-invasive disease characterized by pansinusitis with nasal polyps, with most causative agents being members of the dematiaceous fungi. Reported herein is the ninth Japanese case of allergic fungal sinusitis; an Alternaria species was culturally identified as the etiological agent. The present patient, a 32-year-old man, presented with multiple sinusitis and nasal polyps. Allergic mucin, which is a histological hallmark of this disease, was examined intraoperatively on frozen section. Although characteristic histology, including laminated masses of mucin and aggregates of eosinophils, was seen in HE-stained sections, fungal hyphae were scarce and recognized merely as clear spaces. Because fluorescent stilbene derivatives seem useful for the rapid detection of fungi, Fungiflora Y, a commercially available staining kit that includes a fluorescent stilbene derivative, was applied to the sections, and hyphae were successfully visualized using a fluorescence microscope. This stain takes only several minutes to perform. It is concluded that Fungiflora Y should be used when fungal elements are hard to find on HE stain, especially in cases in which rapid detection of fungus is requested.

Abstract
CONCLUSION In a retrospective study of 239 cases of fungal sinusitis, noninvasive paranasal sinus aspergillosis was most common and successfully treated by endoscopic sinus surgery (ESS) with postoperative sinus irrigation. For the treatment of fungal sinusitis, ESS with or without antifungal agents and control of predisposing factors for secondary cases are recommended. OBJECTIVE The aim of this study was to investigate the clinical characteristics of fungal sinusitis and evaluate the treatment outcomes of primary and secondary fungal infections of the paranasal sinuses. MATERIALS AND METHODS Two hundred thirty-nine cases of fungal infection of the paranasal sinuses seen between January 1997 and December 2006 were retrospectively analyzed by reviewing their medical records. There were 200 cases of primary fungal infection and 39 cases of secondary fungal infection. RESULTS The symptoms of chronic rhinosinusitis such as nasal obstruction, purulent rhinorrhea, and postnasal drip were commonly present in both primary and secondary infections, and the sphenoid sinus was commonly involved in secondary infection. The radiological findings in fungal sinusitis included haziness, calcification, and bone destruction of the involved sinuses. CT scans in 80% of the primary and 69% of the secondary cases revealed calcific densities in a paranasal soft tissue mass. Twenty-eight of 38 cases which had MR showed decreased signal intensities on T1-weighted images and markedly reduced signal intensities surrounded by bright signal on T2-weighted images. In secondary cases, the most common concomitant disease was diabetes mellitus. All patients received surgery including biopsy, ESS, and Caldwell-Luc's operation. Mucosal hypertrophy with fungus ball, which was the most common finding in both types, was found in 124 cases (62%) with primary and in 26 cases (67%) with secondary cases, and aspergillosis was most common, followed by unidentifiable colony, and mucormycosis. Eleven cases received amphotericin-B postoperatively. Two hundred thirty-eight cases showed no recurrence during the mean follow-up period of 11 months.

Abstract
Allergic fungal sinusitis (AFS) is a form of paranasal nasal disease if not managed early often involves bone destruction and extension into the orbit and anterior skull base. We present our study of patients with AFS with intracranial, exdradural extension. This study includes our experience of 26 patients with the histological and immunological diagnosis of AFS based on findings of branching septate fungi interspersed with eosinophilic mucin and Charcot-Leyden crystals without fungal invasion of soft tissue, with intracranial extension. All had erosion of bone, which was observed on computerized tomography (CT) scans, extending intracranially and eight had disease that additionally involved the lamina papyracea. The average age of patients in this study was 25 years (range 9-46). There were 20 male and 6 female patients. All patients were immunocompetent. Skin test against aspergillin showed all patients had Type 1 hypersensitivity. All patients underwent transnasal and/or transmaxillary endoscopic approaches for debridement and eight underwent orbital decompression. No patient underwent craniotomy for removal of intracranial extradural disease. No patient had a cerebrospinal fluid leak. Postoperatively, all 26 were treated with a course of corticosteroids. The follow-up period ranged from 2 to 5 years. We conclude AFS is a unique form of fungal disease that might mimic anterior skull base and paranasal sinus tumors. Most cases can be successfully managed with transnasal and/or transmaxillary endoscopic techniques.

Abstract
PURPOSE OF REVIEW To analyze the role of fungi in the upper and lower airway in chronic rhinosinusitis patients. RECENT FINDINGS Recently, the involvement of the lower airway (as asthma, small airway disease and bronchial hyperresponsiveness) in chronic rhinosinusitis patients had been documented. Fungal spores after inhalation are submerged in the aqueous lining layers of the airway. The site depends on the size of the inhaled spores. The process of inhalation, retention and clearance of fungal spores may explain the positive culture results in both normal subjects and in most chronic rhinosinusitis patients. Fungal culture of different parts of the upper and lower airway in chronic rhinosinusitis patients had no correlation with cellular changes (local eosinophilia) and other clinical parameters. In chronic rhinosinusitis, with persistence of the chronic inflammatory process, the cells may be activated nonspecifically. SUMMARY The role played by fungi in most chronic rhinosinusitis patients as the target antigen of initiation of such chronic inflammation is still debated. With the presence of chronic eosinophilic inflammation in chronic rhinosinusitis, an exaggerated reaction to various inhaled antigens is anticipated. The role of fungi will be confirmed only when T cells within the sinuses are shown to be actively responding to fungal antigens cultured from the sinus and with the demonstration that their elimination will stop the disease.

Abstract
Chronic rhinosinusitis (CRS) is a heterogenous disorder and represents a major public health problem. Although insights into the pathophysiology of CRS have largely expanded over the last two decades, the exact etiology and mechanism of persistence is still unrevealed. CRS is a multifactorial disease, and, with variable evidence, impaired ostial patency, mucociliary impairment, allergy, bacterial or fungal infection (or triggering), immunocompromised state, and environmental and genetic factors have been suggested to be associated or risk factors. Pathomechanisms in CRS are better understood currently, allowing us to characterize and differentiate the heterogeneous pathology of chronic sinonasal inflammation based on histopathology, inflammatory pattern, cytokine profile, and remodeling processes. In nasal polyposis (NP), but not CRS without NP, an abundant eosinophilic inflammation and local immunoglobulin E production could be demonstrated, and Staphylococcus-derived superantigens may at least modulate disease severity and expression. These findings question the current assumption that NP is a subgroup of CRS, but suggest that CRS and NP should probably be considered as distinct disease entities.

Abstract
Sixty cases of fungal sinusitis are presented from 2 institutions, accumulated from 1971 to 2005. Fifty cases were from a large suburban general hospital and 10 from a major university referral center. Two of the 50 and 3 of the 10, respectively, were immunocompromised patients and had acute fulminant disease. This suggests that encountering the various forms of this disease may, in part, be dependent on the referral nature of the institution. The remainder were immune competent and had chronic symptoms of nasal discharge, stuffiness, and facial pain. Imaging studies frequently showed sinus expansion, opacification, and bone erosion, although no clinical or radiographic features were predictive of extrasinus extension. Chronic fungal sinusitis is principally represented by fungus ball/mycetoma and allergic fungal sinusitis. The recent literature suggests a predominance of or a predominant interest in allergic fungal sinusitis. Hyphal colonies and the presence of allergic mucin with scattered organisms are histologic observations and are the respective keys to these diagnoses. However, the etiologic role of the fungus in chronic cases is not settled. Patients with chronic sinusitis who yield positive sinus cultures only, but have no organisms visualized histologically, are not universally regarded as having fungal sinusitis. The interest in fungal sinusitis has generated a prominent role for the pathologist. An awareness of the various forms of the disease and thorough histopathologic study, including submission of all tissues removed at surgery and recognition of allergic mucin, are essential. Acute fulminant/invasive fungal sinusitis may require frozen section for adequate management.

Abstract
Exserohilum is a dematiaceous fungus that may cause a spectrum of diseases in humans, including skin and corneal infection, invasive disease, and allergic fungal sinusitis. The aim of this work is to describe two new cases of Exserohilum infection and to review the literature. The review yielded 33 cases of Exserohilum infection, of which 23 were reported since 1993. Most occurred in regions with hot climates, such as India, Israel, and the southern USA. Impaired immunity was present in the majority of patients with invasive and skin infections, whereas local trauma and atopy were the predisposing factors in those with corneal infections and allergic fungal sinusitis, respectively. Surgical debridement was the principal mode of therapy for allergic fungal sinusitis. Amphotericin B was the initial single antifungal agent used in all cases of invasive disease; the response rate was low but improved with the addition of triazole agents. Outcome appeared to be better than for other mold infections and depended mainly on the underlying diseases.

About an observation of aspergillus sinusitis in an hemodialyzed patient, correlation between chronic maxillary sinusitis, its aspergillus origin and previous dental treatments is emphasized. Eventual severe complications then evolved in immunocompromised patients justify having the knowledge of this possible pathology in hemodialyzed and transplanted patients.

Abstract
BACKGROUND Allergic fungal sinusitis (AFS) has been characterized in adults presenting with chronic sinusitis. Rare reports allude to a similar disease in children. OBJECTIVE To characterize the features of AFS in children. METHODS Children referred to otolaryngology clinics at Arkansas and LeBonheur Children's Hospitals for chronic sinusitis during a 12-year period were studied. This retrospective analysis reviews the following: clinical presentation, laboratory evaluations, radiographic and pathologic findings, and surgical intervention. Twenty patients (age range, 7-18 years; mean age, 12.5 years; median age, 16 years) met previously published criteria for AFS. Thirteen patients were male and 7 were female. Thirteen were African American and 7 were white. RESULTS Presentation at diagnosis included the following: atopy (n = 20), nasal symptoms (n = 20), recurrent sinusitis (n = 18), nasal polyps (n = 18), recurrent headaches (n = 12), asthma (n = 11), proptosis (n = 10), and ocular symptoms (n = 10). All had radiographic evidence of sinusitis and allergy to fungal organisms. IgE levels were elevated in 8 of 9 patients, and 10 of 15 patients had eosinophilia. Surgical specimens demonstrated allergic mucin (n = 11), Charcot-Leyden crystals (n = 2), hyphae or fungal debris (n = 9), and fungal growth (n = 17). All patients underwent endoscopic sinus surgery, with 11 requiring multiple surgical procedures. Postoperatively, 19 patients received intranasal and oral steroids, and all had nasal saline washes. Eleven patients (9 who had undergone multiple surgical procedures) were treated with immunotherapy. Relapse was seen in 55% of patients at 1 year of follow-up. CONCLUSION AFS presents with a higher incidence of proptosis in children when compared with adults. Typically, AFS occurs in atopic children with refractory sinus disease, requiring a high index of suspicion for evaluation and aggressive treatment.

Abstract
PURPOSE OF REVIEW Chronic rhinosinusitis represents a challenge with its poorly understood pathophysiology and limited treatment options. Potential roles of fungi and eosinophils in the etiology and pathophysiology of chronic rhinosinusitis are summarized. RECENT FINDINGS Previously, the fungal role in chronic rhinosinusitis was limited to the rare subgroup, allergic fungal rhinosinusitis. Critical examination of earlier diagnostic criteria for allergic fungal rhinosinusitis reveals limitations. By using updated diagnostic standards and novel sensitive techniques to detect fungi, a higher number of patients can now be diagnosed with fungal rhinosinusitis. A novel non-IgE-mediated immunologic mechanism in chronic rhinosinusitis patients links the predominant eosinophilic inflammation to certain fungi. Overall, these new findings have implications for surgical and medical approaches, including anti-inflammatory and antifungal medications. SUMMARY Several classification schemes and diagnostic criteria describe chronic rhinosinusitis and make comparisons difficult. Preselection of patient groups within the chronic rhinosinusitis population and the lack of sensitive diagnostic techniques have prevented a full understanding of the syndrome complex of chronic rhinosinusitis. New results suggest a broader role for fungi in the pathophysiology of chronic rhinosinusitis, linking the eosinophilic inflammation to the presence of certain molds in the nasal and paranasal cavities. Although fungi are commonly found in nearly everyone, only chronic rhinosinusitis patients respond to them with an eosinophilic inflammation. These findings support a shift in the etiologic understanding of chronic rhinosinusitis away from a bacteriologic infectious pathogenesis to a fungal-driven inflammatory pathophysiology. Herein, the authors review earlier studies and describe an updated view on an old paradigm.

Abstract
PURPOSE OF REVIEW Chronic rhinosinusitis is characterized by a broad diagnostic and etiologic spectrum. It has been postulated that fungal organisms might represent the immunologic target initiating and maintaining the disease process in patients with chronic rhinosinusitis as a common denominator. This review analyzes the available data to describe the current understanding of the role of fungus in the pathophysiology of chronic rhinosinusitis. RECENT FINDINGS Recent findings have demonstrated that using highly sensitive methods, the detection rate of fungi in nasal mucin can be increased to approximately 100% in patients and in healthy controls. If this ubiquitous fungal contamination were to be related to a causative mechanism in chronic rhinosinusitis, there would have to be an immunologic sensitization in patients in contrast with healthy individuals, which is yet not fully understood. However, studies were able to demonstrate cytokine production in blood-derived lymphocytes in the presence of fungi in patients, but not in healthy controls. Several questions arise. If this is a relevant finding, in what percentage of chronic rhinosinusitis patients could it be causative? Is chronic rhinosinusitis, then, a systemic disease? How is the extramucosal target in the mucin presented to the immune system? Is intranasal, topical antifungal treatment a successful option? SUMMARY The role of fungal organisms in the etiology of eosinophilic rhinosinusitis is reviewed with respect to novel findings, and arising questions are discussed in the light of recent investigations.

Abstract
Fulminant-invasive sinus aspergillosis affects immunocompromised patients and is usually lethal because of intracranial complications. Chronic-invasive and non-invasive types occur in non-immunocompromised patients. In these cases, intracranial extension is possible and life-threatening. The effective management of sinus aspergillosis requires early diagnosis by CT and histological classification, surgery, and if necessary, chemotherapy or steroids in case of allergy. Here we report a successfully treated case in a 29-year-old non-immunocompromised patient with chronic-invasive sinus aspergillosis. He presented a recurrent sphenoid sinus aspergillosis with destruction of the clivus and ophthalmoplegia. Diagnostic and therapeutic procedures are described.

Abstract
Allergic fungal sinusitis (AFS) is a noninvasive form of highly recurrent chronic allergic hypertrophic rhinosinusitis that can be distinguished clinically, histopathologically and prognostically from the other forms of chronic fungal rhinosinusitis. There are three invasive (acute necrotising, chronic invasive and granulomatous invasive) and two noninvasive (fungal ball and allergic fungal) forms of fungal rhinosinusitis currently recognised. Confusion in differentiating between the various forms of fungal rhinosinusitis and between other forms of chronic hypertrophic sinus disease (HSD) can be eliminated by adhering to strict diagnostic criteria. Although there are characteristic presenting clinical history and physical examination findings, laboratory test results, including elevated total serum IgE and positive inhalant allergy skin tests, and sinus computed tomography scans showing chronic rhinosinusitis (often with the presence of hyperattenuating sinus contents) diagnosis of AFS is essentially based on histopathology obtained from sinus surgery. Histopathology shows the presence of eosinophilic-lymphocytic sinus mucosal inflammation, extramucosal allergic mucin (that is also seen grossly at surgery as a characteristic 'peanut-buttery' material), and scattered silver stain positive fungal hyphae within the allergic mucin but not in the mucosa. Treatment and follow up of AFS has been based on its immunopathological analogy to allergic bronchopulmonary aspergillosis, a similar noninvasive fungal hypersensitivity disorder of the lung, and its clinical and pathophysiological relationship to other forms of HSD and asthma. Treatment involves aggressive sinus surgery followed by medical management that includes allergen immunotherapy, topical and systemic corticosteroids, antihistamines and antileukotrienes. Total serum IgE levels should be followed postoperatively as they can be prognostic for recurrent disease. Close follow up and coordination of treatment by both medical and surgical physicians as a team leads to the best clinical outcomes. Ongoing studies are being directed at furthering our understanding of the pathophysiological relationships and treatment options for AFS, and other common forms of chronic hypertrophic rhinosinusitis disorders.

Abstract
OBJECTIVE To study the immunity of patients with sinus mycetoma by measuring serum immunoglobulins and IgG subclass levels. STUDY DESIGN AND SETTING Thirty patients with sinus mycetoma, 71 ordinary chronic rhinosinusitis patients without nasal polyps, and 77 ordinary chronic rhinosinusitis patients with nasal polyps were collected. In all subjects, the levels of total serum immunoglobulins and IgG subclasses were measured during surgical treatment. RESULTS Among 30 patients with sinus mycetoma, decreased IgA level was found in 1 patient, and decreased IgM level was found in another 2 patients. There were no significant differences in the levels of total serum immunoglobulins or IgG subclasses between patients with sinus mycetoma and ordinary chronic rhinosinusitis patients with or without nasal polyps. CONCLUSION Immunologic defects cannot be detected in patients with sinus mycetoma by measuring levels of total serum immunoglobulins or IgG subclasses. SIGNIFICANCE Immunoglobulin deficiency may not play an important role in the pathogenesis of sinus mycetoma.

Abstract
Fungi are important etiologic agents of sinusitis. However, features of fungal sinusitis including the histologic spectrum, diagnostic mishaps, incidence, and fungal types have not been systematically studied. From 1996 through 2001, a total of 788 surgical pathology sinus specimens from 384 cases was retrieved. Fungal sinusitis was diagnosed in 58 specimens (7%) from 47 cases (12%). Four histologic categories of fungal sinusitis were identified: (1) allergic fungal sinusitis in 34 cases (copious mucin, abundant eosinophils, Charcot-Leyden crystals (so-called allergic mucin), with rare noninvasive fungal hyphae); (2) mycetoma/fungus ball in 11 cases (tightly packed fungal hyphae without allergic mucin or tissue invasion); (3) chronic invasive fungal sinusitis in 1 case (tissue granulomas with fungal hyphae); and (4) acute fulminant fungal sinusitis in 1 case (fungal vascular invasion). The diagnosis was initially missed in 16/34 (47%) cases of allergic fungal sinusitis despite typical features; incorrect classification was noted in 47% of cases. Sixty-seven percent of cases had positive fungal cultures, dematiaceous fungi being the most common. Allergic fungal sinusitis accounted for the majority of fungal sinusitis. Although misdiagnosis or incorrect classification is rather frequent for fungal sinusitis, awareness of the distinctive morphologic features of this entity may prevent these errors.

Abstract
OBJECT Allergic fungal sinusitis (AFS) is a form of paranasal mycosis that often involves bone destruction and extension into the orbit and anterior skull base. Treatment consists of surgical extirpation and a course of corticosteroids. Despite frequent intracranial involvement, AFS is rarely reported in the neurosurgical literature. METHODS The records of 21 patients with the histological diagnosis of AFS were reviewed. The histological diagnosis was based on findings of branching septated fungi interspersed with eosinophilic mucin and Charcot-Leyden crystals without fungal invasion of soft tissue. The average age of the 21 patients in this study was 25 years (range 9-46) and the male/female ratio was 3.75:1. All patients were immunocompetent. All had a history of chronic sinusitis and imaging findings of expansile disease involving multiple sinuses. Fifteen patients had nasal polyposis, eight had erosion of bone, which was observed on computerized tomography (CT) scans, eight had disease extending intracranially, and six had disease that involved the lamina papyracea. All patients underwent transnasal and/or transmaxillary endoscopic approaches for debridement and irrigation, six underwent orbital decompression, and three underwent a bifrontal craniotomy for removal of intracranial extradural disease. No patient had a cerebrospinal fluid leak. Postoperatively, one patient was treated with amphotericin B and the other 20 were treated with a short course of corticosteroids. The follow-up period ranged from 2 to 19 years. CONCLUSIONS Allergic fungal sinusitis is a unique form of fungal disease that may mimic anterior skull base and paranasal sinus tumors. A cranial base team approach of neurosurgeons and otolaryngologists is recommended. Most cases can be successfully managed with transnasal and/or transmaxillary endoscopic techniques. A craniotomy is rarely indicated unless there is the suspicion of dural invasion or extensive intracranial and/or intraorbital involvement that is inaccessible from below.

Abstract
It is known that eosinophil granular proteins cause tissue damage. To explore how eosinophils degranulate, we studied the degranulation of eosinophils that had migrated around fungal hyphae. In electron microscopic observations of allergic mucin from patients with allergic fungal sinusitis, fungal hyphae were detected, surrounded by numerous eosinophils. A number of eosinophils, including many disintegrated eosinophils, adhered to the cuticular layer of the hyphal surface. Although the fungal hyphae were detected in allergic mucins in all 5 patients, fungal hyphae surrounded by eosinophils were observed in only 1 patient. In the eosinophil cytoplasm, the cell membrane was invaginated, deep, and sheetlike, and the space formed by its infolding was filled with a highly electron-dense substance. This substance appeared to be a mixture of the cuticular substance of the hyphal surface and granular proteins. Thus, the eosinophil phagocytosed the cuticular substance of the hyphae into a sheetlike invaginated space, and released granular proteins into that space. The structure invaginated in the cytoplasm retained its form even after disintegration of the eosinophil, and adhered to the cuticular layer. This structure detected in eosinophils has not been reported previously, and is considered to be an interesting finding from the viewpoint of the function of eosinophils.

Abstract
Allergic fungal sinusitis is a form of noninvasive fungal disease resulting from an IgE-mediated hypersensitivity reaction in atopic individuals. Allergic fungal sinusitis can present with a continuum of symptoms. Accumulation of allergic inspissated mucin may cause simple nasal obstruction or progress to facial deformity with osteolytic destruction and intracranial extension. Multiple species of fungi are now recognized as etiologic factors responsible for initiating the inflammatory response. This article discusses 3 cases involving Aspergillus and Curvularia species, and reviews diagnostic image findings, pathophysiology, and medical-surgical management of this increasingly common disease.

Despite the vast literature regarding fungal infections of the head and neck, little has changed in diagnosis or management of these infections except in the nose and sinuses. Three main points regarding fungal involvement in the paranasal sinuses are evident now. First, fungi may be important in a significant percentage of patients with chronic rhinosinusitis. Second, the pathophysiologic mechanism responsible for fungal rhinosinusitis remains unclear. It may represent an allergic IgE response, a cell-mediated reaction, or a combination of the two. Finally, there is certainly a spectrum of disease thus far defined: allergic fungal sinusitis as defined by Bent and Kuhn [35], eosinophilic mucin rhinosinusitis defined by Ferguson [50], and eosinophilic fungal rhinosinusitis as proposed by Ponikau [45]. Fungal infections of the head and neck are panoramic in distribution and pathophysiology. They represent a broad range of disease of which medical science has only recently begun to uncover the surface. As research begins to unravel the complex host defense mechanisms against these pathogens from a cellular and even genetic level, the body of knowledge will continue to increase exponentially and the ability to treat patients suffering from fungal infections will improve.

Abstract
The purpose of this article is to describe a chronic variant of invasive fungal sinusitis (IFS) and discuss its management. This is a retrospective review of two cases of IFS that were characterized by atypical clinical courses. Patient 1 was a 75-year-old man with noninsulin-dependent diabetes mellitus who came to us with a 5-month history of headache. Computed tomography detected an opacified left sphenoid sinus. After the man failed to respond to medical therapy, he underwent a left endoscopic sphenoidotomy. Pathologic examination revealed that septate, branching fungal hyphae had invaded the soft tissues. The patient was started on oral itraconazole, but later switched to intravenous amphotericin B in response to intracranial extension. The man's disease stabilized, but he died a little more than 1 year later of unrelated causes. Patient 2 was an otherwise healthy 41-year-old woman who came to us with nasal congestion and unilateral nasal polyps. She underwent endoscopic sinus surgery. Pathologic examination identified granulomatous sinusitis and septate, branching fungal hyphae that had invaded the soft tissue of the middle turbinate. The patient was not treated with systemic antifungal medications because of the localized nature of the fungal invasion and the lack of bone invasion or erosion. She has now been symptom-free for 5 years. These two cases demonstrate that IFS can appear in a chronic variant form that is characterized by an indolent course and histologic evidence of tissue invasion by fungal hyphae. The type of treatment is dependent on the extent of the disease on initial examination and the rapidity of its progression.

Abstract
HYPOTHESIS Fungi have been increasingly recognized as important pathogens in sinusitis. However, detection of fungus with conventional culture techniques is insensitive and unreliable. Polymerase chain reaction (PCR) is an exquisitely sensitive assay that can detect the DNA of 10 or less fungal elements. The aim of this study was to compare the sensitivity of conventional culture techniques using PCR analysis. METHODS Nasal swabs and DNA samples were collected from the nasal cavities of control subjects and patients with chronic sinusitis. Fungal-specific PCR analysis and standard cultures were performed on every sample. chi2 analysis was used to test for statistical differences between groups. RESULTS PCR analysis detected fungal DNA in 42% and 40% of control subjects and patients with chronic sinusitis while standard cultures were positive in 7% and 0%, respectively. There was no statistically significant difference in the prevalence of fungi in the normal volunteers and patients with chronic rhinosinusitis. CONCLUSION PCR is significantly more sensitive than nasal swab cultures in detecting the presence of fungi in nasal mucosa. In addition, our study suggests that the presence of fungi alone is insufficient to implicate it as the pathogen in chronic sinusitis.
