Objective: To assess the utility of an intraoperative scoring system for mucormycosis and to predict prognosis by comparing the score with postoperative outcomes., Methods: This study was conducted among 80 patients with mucormycosis who underwent surgical management with mandatory pterygopalatine fossa and infratemporal fossa exploration. All cases were scored using our intraoperative scoring assessment tool. Postoperative outcomes in terms of favourable prognosis and mortality were evaluated and compared with demographics, clinical history and intraoperative findings., Results: An intraoperative score of more than 25 was statistically significant in predicting mortality (p < 0.0001). In all, 86.7% of patients with a score above 25 succumbed to the disease. Statistical significance of mortality (p < 0.05) was observed in those with involvement of pterygopalatine fossa (78.9%), orbit (73.7%), infratemporal fossa (57.9%), cribriform plate (36.8%) and those with history of intake of antiviral drugs (47.4%), use of supplemental oxygen (31.6%) and renal failure (26.3%)., Conclusions: This study enabled better prediction of postoperative prognosis in mucormycosis and reiterated the importance of exploration of pterygopalatine fossa and infratemporal fossa in management and prognostication of invasive fungal sinusitis., (Copyright © 2024 Società Italiana di Otorinolaringoiatria e Chirurgia Cervico-Facciale, Rome, Italy.)

Purpose: Rhino-orbital-cerebral mucormycosis (ROCM) is the most common presentation of mucormycosis. Sinonasal-orbital debridement with exenteration is a life-saving procedure in ROCM patients in view of severe involvement of sinuses and the eyeball. Following the second wave of coronavirus disease 2019 (COVID-19), there was a massive surge in mucormycosis cases in India in post-COVID-19 patients. Of over 300 cases of mucormycosis admitted in our hospital, many underwent exenteration and these specimens were evaluated histopathologically, where fat necrosis was found to be a prominent finding. The spectrum of fat necrosis in ROCM in orbital fat has not been described in literature. Hence, we sought to evaluate the significance and spectrum of orbital fat necrosis in ROCM., Methods: This 3-month retrospective study included 15 cases of ROCM which underwent exenteration. Clinical data, radiologic details, and histopathologic findings were tabulated. Sections were also subjected to Periodic acid Schiff (PAS) and Gomori's methenamine silver (GMS) stains for confirming the fungus., Results: All 15 cases showed fat stranding on computed tomography (CT) scan. On histopathologic examination, various tissue reaction patterns observed included acute/chronic inflammatory infiltrate, suppurative granulomas with giant cells, coagulative and fat necrosis, broad aseptate fungal hyphae with or without angioinvasion, and neural invasion. Fungal hyphae were confirmed with PAS and GMS stains. The spectrum of fat necrosis observed in all the cases included 1) acute necrotizing fat necrosis, 2) ghost adipocytes with or without saponification, and 3) crystalline/gouty fat necrosis., Conclusion: Fat necrosis is a significant finding in ROCM, both on CT scan and histopathology. All three patterns of fat necrosis may be observed simultaneously in a case of ROCM., (Copyright © 2024 Copyright: © 2024 Indian Journal of Ophthalmology.)

Objectives: The primary source of facial mucormycosis is through inhalation of fungal sporangiospores, resulting in invasive disease in paranasal sinuses. However, dental onset mucormycosis has not been well documented in literature. The aim of this study was to describe the clinical characteristics and outcomes of patients with odontogenic onset mucormycosis., Methods: From a large cohort of mucormycosis involving the face between July 2020 and October 2021, we selected patients who had dental symptoms at onset and predominant alveolar involvement with little to no paranasal sinus disease as shown by baseline imaging. All patients had a confirmed diagnosis of mucormycosis through histopathology, with or without the growth of Mucorales in fungal culture., Results: Out of 256 patients with invasive mucormycosis of the face, 8.2% (21 patients) had odontogenic onset. Uncontrolled diabetes was a common risk factor, affecting 71.4% (15/21) of the patients, while recent COVID-19 illness was noted in 80.9% (17/21) of patients. The median duration of symptoms at presentation was 37 days (IQR, 14-80 days). The most common symptoms were dental pain with loose teeth (100%), facial swelling (66.7% [14/21]), pus discharge (28.6% [6/21]), and gingival and palatal abscess (28.6% [6/21]). Extensive osteomyelitis was found in 61.9% (13/21) of the patients, and 28.6% (6/21) had oroantral fistulas. The mortality rate was low, at 9.5% (2/21), with only 9.5% (2/21) of the patients having brain extension and 14.2% (3/21) in the orbit., Conclusion: This study suggests that odontogenic onset invasive mucormycosis may be a separate clinical entity with its own distinct clinical features and prognosis., (Copyright © 2023 European Society of Clinical Microbiology and Infectious Diseases.

Maxillary sinus fungal balls (MSFBs) mostly occur in older individuals and demonstrate female predominance. Early diagnosis is important to avoid treatment delays. Intralesional hyperdensity (IH) indicates the presence of heavy metal deposition within fungal hyphae and has been the most specific characteristic of MSFB on computed tomography (CT). For those without IH on CT, the diagnosis of MSFB remains challenging. This study aimed to characterize clinical presentation of MSFB with and without IH and to study factors contributing to MSFB with no IH formation. We retrospectively identified 588 patients with MSFB. The clinical characteristics and CT findings were reviewed. Patients with unilateral MSFB had a mean age of 57.4 years and demonstrated female predominance (64.63%). The female-to-male ratio was highest at 51-60 years (2.02) and rose to 2.60 in MSFB with IH only. Compared to those with IH, MSFB without IH was significantly more common in males (OR = 2.49), in those with diabetes mellitus (DM) (OR = 1.87), adjacent maxillary odontogenic pathology (OR = 1.75). Complete opacification on CT was less common in MSFB without IH (OR = 0.60). Patients with MSFB without IH were more likely to have DM, no female predominance, adjacent maxillary odontogenic pathology, and partial opacification of the sinus, compared to those with IH. These may be helpful in better understanding of the formation of MSFBs without IH, early identification of them and prevention of post-operative recurrence., (© 2021. The Author(s).)

An increasing incidence of rhinoorbitocerebral mucormycosis (ROCM) among patients with COVID-19 has recently been reported in India. We report the imaging findings for 25 patients with COVID-19 and invasive ROCM at a single hospital in India. Findings included sinus wall erosions ( n = 20), air within bony sinus structures ( n = 11), and focal mucosal nonenhancement ( n = 8). Orbital, vascular, and intracranial complications were also observed. Radiologists should recognize the increasing incidence of ROCM among patients with COVID-19 to facilitate early diagnosis.

Objectives: Paranasal sinus fungus ball is a common non-invasive mycosis with excellent long-term surgical treatment results. The present systematic review and meta-analysis were undertaken to define current treatment concepts and success rates in paranasal sinus fungus ball treatment., Methods: Systematic searches were performed in multiple databases with criteria designed to include all studies published until May 2020 focusing on paranasal sinuses fungus ball treatment in humans. We selected studies including at least 10 patients, specifying treatment modalities, providing a minimum 6-month follow-up, and objectivating treatment success. After duplicate removal, abstract and full-text selection, and quality assessment, we reviewed eligible articles for treatment modalities and success rates. Success rates were pooled in a random effect meta-analysis and compared according to the use of intraoperative sinus lavages and postoperative antibiotics., Results: Among 740 unique citations, 14 studies were deemed eligible. Most (n = 11) were retrospective case series. All studies relied on endoscopic sinus surgery. Intraoperative lavages were proposed in 10 studies and postoperative antibiotics in 7 (for all patients in 5 studies and for selected patients in 2). No significant heterogeneity was observed between results (Cochran's Q P  = .639, I 2 test = 0). Treatment success rate was 98.4% (95% confidence interval 97.4%-99.3%). Intraoperative sinus toilette and postoperative antibiotics didn't significantly improve the success rate., Conclusion: Endoscopic sinus surgery shows excellent results in fungus ball treatment. Further prospective studies might help further reducing antibiotics prescriptions in these patients and improve their management.

Aim: To analyse combined computed tomography (CT) and magnetic resonance imaging (MRI) characteristics of invasive rhino-orbital mucormycosis (IROM) in post-COVID-19 infection patients for accurate diagnosis and delineation of the extent of involvement., Materials and Methods: A retrospective analysis was undertaken of 50 patients who developed IROM post-COVID-19 infection who underwent combined CT/MRI evaluation., Results: The age range of the 50 affected patients was 23-73 years. Out of these, 41 were diabetic. CT/MRI showed predominant involvement of the maxillary (n=26) and ethmoid (n=19) sinuses. Extension of disease to the orbit (n=35), cavernous sinus (n=18), hard palate (n=15), skull base (n=8), and intracranial involvement (n=3) was seen. Perineural spread of the disease was analysed along all divisions of the trigeminal nerve and its branches. MRI showed T2-hypointense soft-tissue thickening with heterogeneous contrast enhancement with corresponding hyperdensities on CT diagnosing the presence of fungal elements., Conclusion: Clinicians should be aware of the possibility of IROM post-COVID-19 infection. Conjunctive use of CT, which depicts bone destruction and other reactive bony changes along with MRI, which reveals characteristic findings of soft-tissue thickening of the involved sinuses with extension of disease to the orbits, cavernous sinus, dura, hard palate, skull base, and intracranial structures. Accurate diagnosis and early recognition of the disease and its extension with appropriate use of these techniques helps to initiate appropriate and timely treatment, which is vital to prevent a fatal outcome., (Copyright © 2021 The Royal College of Radiologists.

Among the ever-increasing literature of the coronavirus disease 2019 (COVID-19), there have been reports on several complications in association with severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), such as secondary bacterial and fungal infections. We report a 61-year-old woman with a past history of diabetes mellitus who presented to our hospital suffering from COVID-19 infection. During the course of her hospitalization, the patient developed chemosis and proptosis in both eyes, ultimately leading to a diagnosis of invasive rhino-orbital-cerebral mucormycosis and cerebrovascular thrombosis. This study strengthens the possible association between the occurrence of COVID-19 and invasive mucormycosis infection, providing new impetus for further investigations to substantiate this correlation., (© 2021.

Aim: To report the frequency and factors affecting patients', globe and vision survivals in rhino-orbito-cerebral mucormycosis (ROCM)., Methods: This is a retrospective study of 63 patients (79 eyes) with biopsy-proven ROCM at a university hospital 2008-2016. Systemic and ophthalmic manifestations, imaging, management and final outcomes were recorded. Globe survival was defined as no exenteration and vision survival as final visual acuity of light perception and more., Results: Mean age was 55.5 (SD 12.9) years with no gender preference. Diabetes was the most common underlying disease (68.3%). Patient survival was observed in 57.1 % (36/63). Presence of frozen eye (OR 4.6), nasal mucosal involvement (OR 7.3) and shorter duration of antifungal therapy (OR 1.03) were significantly associated with lower patient survival. Exenteration did not significantly change the survival. Globe survival was detected in 43% (34/79). Higher white blood cell (WBC) count was associated with a lower globe survival (p=0.02). Vision survival was observed in 25.3% (20/79) in whom younger age was significantly associated with a worse vision survival., Conclusion: Patient, globe and vision survivals were 57%, 43% and 25%, respectively. Exenteration did not affect the patients' survival. While frozen eye and nasal mucosal involvement were significantly associated with a lower survival, higher WBC count significantly increased the risk of exenteration., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Mucormycosis is a severe infection that affects a variety of patients, including immunocompromised children and neonates. Given improved survival rates from advances in the treatment of malignancies, the population at risk for mucormycosis is increasing. We conducted a systematic review of cases of mucormycosis in children in the English-language literature reported between August 2008 and June 2017 and analyzed the clinical characteristics, diagnosis, management, and outcome of those infections. The most common underlying diagnoses included neutropenia (41%), hematologic malignancy (39%), prematurity (13%), and hematopoietic stem cell transplant (11%). Sinus disease (28%) and disseminated disease (24%) were the most common presentations. Rhizopus spp were the most common organisms isolated (22%). Amphotericin B remains the backbone of treatment and was prescribed in 86% of these cases. The resulting mortality rate remains high (32%). We provide here the results of a literature review of mucormycosis in children, including its epidemiology and clinical manifestations, and describe current advances in its diagnosis and treatment., (© The Author(s) 2019.

Background: Maxillary fungus ball (FB) is the most frequent paranasal localization., Objective: To review clinical presentation, surgery and results of treatment in our series of patients with maxillary FB. To review the literature concerning treatment of maxillary FB., Patients and Methods: 48 patients with a diagnosis of maxillary FB were treated with endoscopic sinus surgery (ESS) alone or in association with external approaches. Before surgery all patients received computed tomography (CT), nasal endoscopy and dental examination. All the patients were followed for 1 year after surgery. Studies concerning surgical treatment of maxillary FB from 2006 were reviewed., Results: The mean age of patients was 53.6 ± 11.9 years. 20 patients (41.6%) did not present any symptom, 19 patients (39.7%) had nasal symptoms, 3 patients (6.2%) had facial pain, 6 patients (12.5%) had a combination of both. Endoscopic examination was positive in 31 patients (64.6%), 17 patients (35.4%) showed negative findings. Logit regression model demonstrated that clinical symptoms contribute to the prediction of a positive endoscopic examination. 25 patients (52.1%) presented odontogenic factors. Complete clinical and radiological resolution of FB was observed in 46 patients (95.8%)., Conclusions: Comparing our sample to the studies reviewed we may concluded that odontogenic factors were frequently reported and should be treated at the same time of maxillary FB. ESS alone or in association with external approaches is an effective treatment for patients with maxillary FB., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Purpose of Review: There is a lack of consensus with regards to the diagnosis and treatment of sinus disease in children with cystic fibrosis. Here, we review literature from the past 18 months in order to highlight the way forward in this contentious field., Recent Findings: Most of the literature (from the past 18 months) on sinus disease in pediatric cystic fibrosis focused on treatment approaches, bacteriology and immunology, and health-related quality-of-life (HRQOL) instruments. Quality studies have demonstrated that functional endoscopic sinus surgery (FESS) is as safe in children with or without cystic fibrosis; that the microbiology of the paranasal sinus in children with cystic fibrosis is different than that of their lungs; and, that HRQOL instruments may prove useful in determining sinonasal disease severity in children with cystic fibrosis., Summary: Medical and surgical approaches appear to be viable in the treatment of sinonasal disease in pediatric cystic fibrosis; the microbiology and immunology of pediatric cystic fibrosis is proving more complex and nuanced than initially believed; and, HRQOL instruments show promise in reconciling differences between observable and clinically relevant sinus disease in pediatric cystic fibrosis patients.

Background: Nasal irrigations with antibiotics are used to eradicate Pseudomonas aeruginosa from the upper airways in patients with cystic fibrosis (CF) and thereby avoid lung colonisations; nevertheless, the efficacy is uncertain., Methodology: The aim of this study was to investigate the accessibility and durability of solutions in the sinuses before and after sinus surgery. The participants irrigated their noses with radioactively marked saline and were evaluated using a dynamic SPECT/CT scan. The preoperative and postoperative (after 30 days) examinations were compared., Results: Twelve CF patients were included. In 10 out of the 24 scanned maxillary sinuses an improvement was seen postoperatively compared with the preoperative fluid volume. Notably, in 7 out of the 24 sinuses the mucosa was so swollen postoperatively that no fluid was detected. Ten patients had developed their frontal sinuses. We observed no fluid in the frontal or sphenoid sinuses, neither before nor after surgery. At best, a mean of 23% of the maxillary sinuses were filled with fluid; thus, all sinuses had postoperatively areas of the mucosa that did not have contact with the fluid. A mean of 76% of the initial volume was present after 30 min in the maxillary sinuses., Conclusion: Fluid-depositing using nasal irrigation will not sufficiently or not at all get in contact with all the sinus mucosa despite of sinus surgery. Thus, the efficacy of topical deposition of antibiotics is presumably reduced.

To describe a fatal case of invasive Aspergillus flavus sinusitis in a 43-year old female with sickle cell disease (SCD) complicated by intracerebral aspergilloma and invasive Salmonella infection. Cerebral aspergilloma carries a very high mortality rate. The patient developed post-craniotomy intracerebral hemorrhage at the site of biopsy, Salmonella species sepsis and ventriculitis. She presented with a 2-month history of headache, dizziness, personality and behavioral changes, and vomiting. Initial clinical evaluation raised the suspicion of brain tumor. Brain magnetic resonance imaging revealed a left frontal, thick-walled ring-enhancing lesion with extensive surrounding edema suggestive of a neoplastic lesion, or a contiguous inflammatory or infectious process from the skull base. Despite early diagnosis and appropriate antifungal and surgical management, she eventually died from severe infection and respiratory arrest. In conclusion, invasive aspergillosis should be included in the differential diagnosis of SCD patients with central nervous system (CNS) lesions.

In this report, we describe the case of a young, diabetic girl with ketoacidosis who suffered sudden loss of vision of the right eye. The loss of vision was caused by an invasive rhino-orbital-cerebral fungal infection (mucormycosis) with extensive periorbital thrombosis. Despite maximal antifungal and surgical treatment (including exenteration of the right orbit), the clinical situation deteriorated. It was only after overcoming the difficulties of managing her hyperglycaemia that the patient's condition stabilised and her life was saved. Another factor contributing to this girls' survival was the swift diagnosis of mucormycosis, which was made soon after the onset of symptoms. Because of this, treatment could be started almost immediately., Competing Interests: Competing interests: Icmje-forms have been signed by all authors., (© BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

An 86-year-old patient was hospitalized for fever and left acute orbital syndrome (red eye with moderate visual impairment, chemosis, ophthalmoplegia without proptosis, or any fundus involvement). CT scan showed superior ophthalmic vein and cavernous sinus enlargement complicating ipsilateral sphenoidal sinusitis. Magnetic resonance imaging (MRI) demonstrated the left cavernous sinus thrombosis extended to the ipsilateral jugular vein and transversal sinus (Lemierre syndrome). Intravenous broad-spectrum antibiotics and curative anticoagulation were prescribed. Blood cultures allowed the identification of Streptococcus intermedius and Staphylococcus warneri species. Evolution was favorable and the patient was discharged 3 weeks after. Antibiotics and anticoagulation were carried out for a total duration of 4 and 12 weeks, respectively. Lemierre syndrome is a potentially life-threatening emergency rarely encountered; thus, ophthalmologists should be cognizant of clinical and radiological features. Broad-spectrum antibiotics are the mainstay of treatment. Curative anticoagulation may be added if no blood coagulation disorder nor bleeding on neuroimaging has been identified.

Introduction: Early diagnosis of acute invasive fungal rhinosinusitis (AIFR) is crucial for patients prognosis and may reduce the extent of surgical debridement. Initial evaluation usually includes paranasal Computed Tomography (CT), with an emphasis on bony erosion which is considered a specific but insensitive radiologic sign. Most studies made no distinction between Aspergillus and Mucor species while addressing CT findings. In this study, we seek to evaluate whether bony erosion on paranasal CT is a significant and reliable finding in the initial evaluation of invasive paranasal mucormycosis., Methods: A retrospective review of pre-operative non-contrast craniofacial CT scans of patients diagnosed with acute invasive fungal rhinosinusitis (AIFR) caused by Mucor species for the presence of bony erosion., Results: A total of 13 patients (9 males, 4 females) were included. Twelve patients were immunosuppressed due to various hematological malignancies. Six patients underwent debridement due to gross intraoperative findings of bony fungal invasion, but only one patient had evidence of bony erosion on the pre operative paranasal CT., Conclusion: Bony erosion on paranasal CT is an exceptionally insensitive radiologic sign for establishing or rejecting the diagnosis of Mucor induced AIFR. The mainstay of confirming or rejecting the diagnosis of AIFR is by physical examination, endoscopy and oriented biopsy of suspicious mucosal lesions.

Purpose: To describe the non-exenteration management of sino-orbital fungal infection, a life-threatening condition for which orbital exenteration is generally considered a first-line treatment., Methods: A retrospective case series is presented of 7 orbits in 6 consecutive patients admitted and treated at 2 major metropolitan tertiary teaching hospitals in Sydney, New South Wales, Australia., Results: Seven orbits in 6 consecutive patients with sino-orbital fungal infection were treated conservatively with surgical debridement and intravenous antifungal agents. Four patients were immunosuppressed and the other 2 patients were otherwise healthy. All presented with pain, proptosis, or loss of vision. Causative organisms found were Mucormycoses, Aspergillus, and Scedosporium prolificans. Exenteration was avoided in all patients as part of their planned management and 5 patients, including 1 with bilateral disease, survived their disease without exenteration. Medical treatment included intravenous liposomal amphotericin B or voriconazole. A single immunosuppressed patient deteriorated and as a last resort, exenteration was performed, but this made no difference to his clinical course and in retrospect could have been avoided as he died of multiple cerebral metastases diagnosed shortly after his deterioration., Conclusion: The authors recommend that patients with sino-orbital fungal disease preferably be treated conservatively, without orbital exenteration.

Tearing is a frequently encountered chief complaint in an ophthalmologist's office. Certain associated atypical symptoms may warrant further workup. The authors present a case of a patient presenting with painful tearing which elicited further evaluation with CT imaging. This revealed a maxillary sinus fungus ball as the cause for the patient's tearing.

Purpose: To report 2 immunocompromised patients with sino-orbital necrotizing pseudomonas infections and review the literature., Methods: This is a noncomparative, retrospective case series, and review. The clinical data of 2 patients with histopathologic and microbiologic diagnoses of pseudomonas sinus infections causing orbital cellulitis were obtained from medical records. A retrospective literature review was performed on all reported cases of periorbital pseudomonas infections., Results: One patient with acquired immune deficiency syndrome was noted to have orbital cellulitis with clear visualization of eschar in the middle turbinate on nasal endoscopy. A second patient also had orbital cellulitis with ophthalmoplegia and presence of eschar in the sinus. Both patients had some degree of erosion through the lamina papyracea found on orbital imaging and both had intact vision without optic neuropathy. Pseudomonas infection was confirmed in both cases with permanent histopathology and cultures from conservative sinus debridement., Conclusions: Pseudomonas sino-orbital infections must be considered in the differential diagnosis in cases of eschar and orbital wall erosion especially when vision is preserved in immunocompromised individuals. This finding obviates the need for radical debridement including orbital exenteration, which can be indicated in cases of invasive fungal disease.

Background: Rhino-orbito-cerebral mucormycosis(ROCM) is an invasive fungal infection that usually occurs in immunocompromised patients and sometimes presents as orbital apex syndrome(OAS) initially. It is rapidly fatal without an early diagnosis and treatment. We report the cases of invasive ROCM presenting with OAS initially in order to raise the attention of clinicians., Methods: We retrospectively investigated eleven cases of invasive ROCM presenting initially with OAS admitted between January 2006 and December 2013. We analyzed clinical features, results of laboratory and radiological examinations, nasal endoscopy, aggressive surgical excision and debridement, and medical management outcomes of each case., Results: A total of eleven cases of invasive ROCM with OAS as an initial sign were presented. Mucormycosis was accompanied by type II diabetes mellitus in nine cases, renal transplant in one case, and injury caused by traffic accident in one case. Anterior rhinoscopy revealed palatine or nasal necrotic lesions in all patients, and transethmoidal optic nerve decompression was carried out in three patients at the same time. CT scan revealed rhino-orbital-cerebral involvement in every patient. All patients were given intravenous amphotericin B. Nine patients underwent surgical debridement of necrotic tissue. Three patients survived., Conclusions: ROCM is a severe, emergent and fatal infection requiring multidisciplinary management. It may often present with OAS initially. For ophthalmologist, mucormycosis must be considered in immunocompromised patients presenting with OAS initially, and anterior rhinoscopy is imperative before hormonotherapy, even in the cases absent of ketoacidosis induced by diabetes mellitus.

Objectives/hypothesis: Fungus balls are a common disease of the paranasal sinuses, usually involving the maxillary sinus. To clarify the pathology, we analyzed patients treated for maxillary sinus fungus balls to see whether the latter correlated with dentogenic factors., Study Design: Retrospective case analysis., Methods: Cases of maxillary sinus fungus balls diagnosed between January 2000 and December 2013 were analyzed retrospectively. Patients' charts were reviewed for diagnosis, gender, and age. Paranasal sinus computed tomography (CT) scans were reviewed according to the side of the fungus ball, calcifications/opacifications, and dentogenic factors., Results: In 98/102 patients (96.1%), 157 dentogenic factors could be identified on the side affected by a fungus ball. On the contralateral healthy side, there were 125 dentogenic factors. In four (3.9%) of the patients, no dentogenic pathology was identified on the CT scan. The presence of dentogenic factors (regardless of number) was significantly associated with a fungus ball compared to the healthy side (P = .024, χ(2) test, odds ratio: 2.72 [95% confidence interval: 1.02-7.23])., Conclusions: Dentogenic factors regardless of type potentially correlate with the presence of maxillary sinus fungus ball. Unlike the overall presence of dentogenic factors, the particular dentogenic factors in an individual patient do not significantly influence the development of fungus balls. After diagnosis of dentogenic pathology in penetrated maxillary sinus floors, patients should be closely monitored and informed about their higher risk of developing a fungus ball., (© 2015 The American Laryngological, Rhinological and Otological Society, Inc.)

Objective: Invasive sino-orbital fungal infections are life-threatening complications of immunonosupression that are difficult to treat. Currently there are no standard treatment guidelines. The most widely accepted therapy includes parenteral anti-fungal therapy and surgical debridement of sinuses with orbital exenteration, a procedure that is not only disfiguring, but may increase morbidity. Injection of retrobulbar Liposomal Amphotericin B (L-AMB) is an alternative approach that provides local administration to infected tissues. The adjunct use of anti-fungal retrobulbar injections not been extensively reviewed in treating sino-orbital infection. We are reporting the multimodal approach of using L-AMB retrobulbar injections in combination with sinus debridement, intravenous (IV) anti-fungal therapy, and hyperbaric oxygen (HBO) for the management of sino-orbital infection., Method & Results: Review of literature of 12 cases and retrospective evaluation of one patient with sino-orbital Aspergillus flavus infection on chemotherapy for T-cell acute lymphocytic leukemia treated with retrobulbar Amphotericin B, IV anti-fungal agents, and hyperbaric oxygen therapy. Clinical characteristics, radiographic features, management techniques, and clinical outcomes are described., Conclusion: Retrobulbar Amphotericin B injection may be an effective adjunct to hyperbaric oxygen and parenteral anti-fungals in the control of sino-orbital fungal infections.

Chronic invasive aspergillosis of the sinus is frequently fatal in the absence of early surgical and chemotherapeutic intervention because of its invasion of vascular tissue. We attempted to control a case of inoperable invasive aspergillosis of the sinus with micafungin and itraconazole oral solution. We prescribed a daily oral dose of 400 mg of itraconazole, which is twice the usual dose, and monitored the serum concentration of the drug. Finally, we were able to control the spread of the lesion. This case indicates that combination therapy with micafungin and a daily dose of 400 mg itraconazole oral solution is an alternative treatment strategy for inoperable invasive aspergillosis of the sinus., (Copyright © 2014 Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases.

Introduction: Sinus aspergillosis is a potential complication after root canal therapy of antral teeth. Indeed, zinc oxide-eugenol cement overfilling in the sinus may promote fungal infection. Moreover, if sinus aspergillosis triggers chronic sinusitis with aspergilloma, it may also lead to invasive phenomena, especially for immunocompromised patients., Methods: We reported a sinus aspergillosis case of a patient treated with infliximab (Remicade; Janssen Biologics BV, Leiden, Netherlands). The purpose of this article was to explore the mechanisms of this pathosis, especially the impact of the root canal sealer overextension, which is a contributing factor for fungal infection. The surgical management and the follow-up are also described., Results: Six months after surgery, the patient showed no clinical signs and presented with a healthy and airy right maxillary sinus on the computed tomography scan., Conclusions: In conclusion, prevention and screening of aspergillosis of maxillary sinus may be considered before starting an anti-tumor necrosis factor alpha therapy., (Copyright © 2015 American Association of Endodontists.

Zygomycosis is an invasive disease that affects both immunocompetent and immunocompromised, depending on the type of strain. This disease diagnosis is clinical and histopathological, and its treatment is based on antifungal therapy and surgical cleaning. This paper reports a case of a boy with invasive zygomycosis rinofacial who final treatment was successful after underwent antifungal and surgical therapies.

The purpose of this case report is to illustrate the cause of this patient's headache and sinus pain in the setting of a unique environmental exposure: the patient ingested yogurt only days before presentation. This particular brand of yogurt caused controversy in early September 2013 when the manufacturer voluntarily recalled all flavors. The yogurt was found to be contaminated with Mucor circinelloides. The recall was triggered by the FDA, after receiving many complaints from consumers affected by temporary gastrointestinal symptoms such as abdominal cramping, diarrhea, and nausea. This patient was diagnosed with Rhinocerebral mucormycosis through fungal culture of the affected area. He was specifically colonized with Mucor circinelloides, a variant that rarely causes disease in humans. According to a literature review, only eight cases of mucormycosis in adults caused by this strain were documented before 2009.
