UNASSIGNED: We report a case of recurrent nasopharyngeal carcinoma postnasopharyngectomy, presenting with headaches. MRI revealed abnormal signals of the clivus with enhancement, and FDG PET/CT indicated intense uptake in the nasopharynx, clivus, and left neck lymph nodes. Bone SPECT/CT showed bony erosion and uptake in bilateral skull base areas. Biopsy confirmed aspergillosis. Despite the challenges in distinguishing tumor invasion from Aspergillus infection on MRI, bone SPECT/CT, and FDG PET/CT, the short postsurgery period and extensive uptake suggested skull base osteomyelitis.

UNASSIGNED: Otomycosis is common in environments with hot, humid weather, and it may be challenging to manage.
UNASSIGNED: To profile common clinical presentations, the pathogenic fungi, the treatment modalities with responses, and explore clinical factors associated with having positive fungal culture in Otomycosis.
UNASSIGNED: Retrospective review of patients with Otomycosis. Demographic and clinical parameters, otoscopic findings and mycological study results were recorded. The treatment modalities used and treatment response were summarized. Comparative statistical analyses of associated factors to positive fungal culture were performed with Chi square test, and Student\'s t-test, using SPSS version 22.0.
UNASSIGNED: Total of 71 patients with M: F=1:1.8, mean age 38.5±19.8 years. Average duration of symptoms was 5.4 ±4.6 weeks; common presenting complaint was itchy ear (33.8%). Majority of patients (85.9%) had unilateral ear involvement, 50.0% applied ototopic medications before presentation, 8.5% had multiple co-morbidities. 20 patients had positive fungal culture results; common fungal isolate was Aspergillus niger 9 (45.0%).Clinical factors associated with positive culture of fungus were age, non-previous use of ototopic drugs, and presence of co-morbidity. The most common treatment was local ear debridement and use of topical antifungal creams. Majority (91.5%) of the patients responded with resolution of fungal infection. Complications rate was 8.4%.
UNASSIGNED: Otomycosis commonly present with itchy ears, the pathogenic fungi commonly being Aspergillus species. The factors associated with positive fungal culture were age, non-usage of ototopic agents and presence of co-morbidity. Treatment modality used was local debridement and topical antifungal agents, which produced favourable response in most patients.

OBJECTIVE: To assess the prevalence and relevance of invasive fungal disease (IFD) during veno-arterial (V-A) extracorporeal membrane oxygenation (ECMO).
METHODS: Retrospective analysis from January 2013 to November 2023 of adult V-A ECMO cases at a German University Hospital. Parameters relating to IFD, demographics, length of stay (LoS), days on ECMO and mechanical ventilation, prognostic scores and survival were assessed. Multivariable logistic regression analyses with IFD and death as dependent variables were performed. Outcome was assessed after propensity score matching IFD-patients to non-IFD-controls.
RESULTS: 421 patients received V-A ECMO. 392 patients with full electronic datasets were included. The prevalence of IFD, invasive candidiasis and probable invasive pulmonary aspergillosis was 4.6%, 3.8% and 1.0%. Severity of acute disease, pre-existing moderate-to-severe renal disease and continuous kidney replacement therapy were predictive of IFD. In-hospital mortality (94% (17/18) compared to 67% (252/374) in non-IFD patients (p = 0.0156)) was predicted by female sex, SOFA score at admission, SAVE score and IFD (for IFD: OR: 8.31; CI: 1.60-153.18; p: 0.044). There was no difference in outcome after matching IFD-cases to non-IFD-controls.
CONCLUSIONS: IFD are detected in about one in 20 patients on V-A ECMO, indicating mortality >90%. However, IFD do not contribute to prognosis in this population.

UNASSIGNED: In the second wave of COVID-19 pandemic, there has been an increase in number of cases with Post-COVID-19 fungal osteomyelitis of jaws. Aspergillosis was found to be one of the causes of osteomyelitis of jaw bones in these patients.
UNASSIGNED: To evaluate the incidence and pattern of osteomyelitis of jaw due to aspergillosis in post-COVID-19 patients and to discuss the management protocol of the same.
UNASSIGNED: Data were obtained at our institution from the period of January 2021 to June 2021. Patients of all age groups with Post-COVID-19 osteomyelitis of jaw due to aspergillosis and those with combined aspergillosis and mucormycosis infection were included. Patients having rhino-orbito-cerebral fungal infection were excluded.
UNASSIGNED: A total of 47 patients reported to our center. Demographically the average age of the patients was 49.11 years with 72% being males. All 47 patients (N = 100%) had received steroids. 21 of them (N = 44.7%) had diabetes mellitus and 14 (N = 29.8%) patients had other comorbidities. Out of 47 patients, 42 (N = 89.7%) patients were diagnosed with aspergillosis and the remaining 5 (N = 10.3%) cases had a mixed fungal infection of mucormycosis and aspergillosis. On fungal culture Aspergillus flavus was the most common species detected followed by Aspergillus niger and Aspergillus fumigatus. All patients were treated with oral Voriconazole and local surgical debridement. Prompt laboratory testing such as a timely KOH mount, galactomannan test, beta-D-glucan test, histopathology of tissue specimens could help to give an early and definitive diagnosis. The mortality rate we encountered in this study was nil.
UNASSIGNED: Early and definitive diagnosis and immediate initiation of antifungal drug therapy and surgical intervention will significantly reduce the rate of morbidity and mortality.

BACKGROUND: Surveillance studies are crucial for updating trends in Aspergillus species and antifungal susceptibility information.
OBJECTIVE: Determine the Aspergillus species distribution and azole resistance prevalence during this 3-year prospective surveillance study in a Spanish hospital.
METHODS: Three hundred thirty-five Aspergillus spp. clinical and environmental isolates were collected during a 3-year study. All isolates were screened for azole resistance using an agar-based screening method and resistance was confirmed by EUCAST antifungal susceptibility testing. The azole resistance mechanism was confirmed by sequencing the cyp51A gene and its promoter. All Aspergillus fumigatus strains were genotyped using TRESPERG analysis.
RESULTS: Aspergillus fumigatus was the predominant species recovered with a total of 174 strains (51.94%). The rest of Aspergillus spp. were less frequent: Aspergillus niger (14.93%), Aspergillus terreus (9.55%), Aspergillus flavus (8.36%), Aspergillus nidulans (5.37%) and Aspergillus lentulus (3.28%), among other Aspergillus species (6.57%). TRESPERG analysis showed 99 different genotypes, with 72.73% of the strains being represented as a single genotype. Some genotypes were common among clinical and environmental A. fumigatus azole-susceptible strains, even when isolated months apart. We describe the occurrence of two azole-resistant A. fumigatus strains, one clinical and another environmental, that were genotypically different and did not share genotypes with any of the azole-susceptible strains.
CONCLUSIONS: Aspergillus fumigatus strains showed a very diverse population although several genotypes were shared among clinical and environmental strains. The isolation of azole-resistant strains from both settings suggest that an efficient analysis of clinical and environmental sources must be done to detect azole resistance in A. fumigatus.

BACKGROUND: Invasive pulmonary aspergillosis (IPA) is a relatively common infection in patients with acute myeloid leukaemia (AML), and is associated with high mortality rates. Optimising early detection is key to reduce the burden of IPA in this population. In this retrospective cohort study, we evaluated the added value of baseline chest CT before start of classical induction chemotherapy.
METHODS: Adult patients receiving first-line intensive chemotherapy for AML were included if a baseline chest CT scan was available (±7 days). Data were collected from the electronic health record. IPA was classified using the EORTC/MSGERC 2020 consensus definitions.
RESULTS: Between 2015 and 2019, 99 patients were included. During first-line treatment, 29/99 (30%) patients developed a probable IPA. Baseline chest CT was abnormal in 61/99 (62%) and 14/61 (23%) patients had typical radiological signs for IPA. An abnormal scan showed a trend towards higher risk for IPA (hazard ratio (HR): 2.12; 95% CI 0.95-4.84). Ground glass opacities were a strong predictor for developing IPA (HR 3.35: 95% CI 1.61-7.00). No probable/proven IPA was diagnosed at baseline; however, a bronchoalveolar lavage (BAL) at baseline was only performed in seven patients. Twelve-week mortality was higher in patients with IPA (7/26, 27% vs. 5/59, 8%; p = .024).
CONCLUSIONS: Baseline chest CT scan could be an asset in the early diagnosis of IPA and contribute to risk estimation for IPA. In patients with an abnormal baseline CT, performing a BAL should be considered more frequently, and not only in patients with radiological findings typical for IPA.

OBJECTIVE: To determine if a cytochrome (CYP) P450 enzyme inhibitor can maintain therapeutic plasma levels of voriconazole when administered orally.
METHODS: 11 healthy, common ravens (Corvus corax).
METHODS: Birds were randomly assigned to pilot study groups to receive voriconazole orally alone or combined with a CYP inhibitor. Pilot studies with 3 CYP inhibitors launched the main study using ciprofloxacin (20 mg/kg) followed 1 hour later by voriconazole (6 mg/kg) every 12 hours for 14 days. Plasma voriconazole concentrations were measured at various time points by HPLC-MS. The study period lasted from September 2016 to December 2020.
RESULTS: The birds failed to maintain therapeutic plasma levels of voriconazole during multidose administration alone or following preadministration with various CYP inhibitors. For the 14-day study period, voriconazole reached a maximum plasma concentration of 2.99 μg/mL with a time-to-peak drug concentration of 1.2 hours following preadministration of ciprofloxacin. One bird was removed from the study due to lethargy, but the other birds completed the study without incident.
CONCLUSIONS: Ciprofloxacin (20 mg/kg) followed by voriconazole (6 mg/kg) maintained the concentration of voriconazole within the recommended therapeutic range of 0.5 to 5 μg/mL without toxicity. Ciprofloxacin prevented the saturable metabolism of voriconazole and maintained these levels for the study duration. This drug combination could be used in the treatment of chronic aspergillosis in the common raven.

OBJECTIVE: Invasive aspergillosis (IA) is a major cause of mortality in immunocompromised patients and it is difficult to diagnose because of the lack of reliable highly sensitive diagnostics. We aimed to identify circulating immunological markers that could be useful for an early diagnosis of IA.
METHODS: We collected longitudinally serum samples from 33 cases with probable/proven IA and two matched control cohorts without IA (one with microbiological and clinical evidence of bacterial or viral non-fungal pneumonia and one without evidence of infection, all matched for neutropenia, primary underlying disease, and receipt of corticosteroids/other immunosuppressants) at a tertiary university hospital. In addition, samples from an independent cohort (n = 20 cases of proven/probable IA and 20 matched controls without infection) were obtained. A panel of 92 circulating proteins involved in inflammation was measured by proximity extension assay. A random forest model was used to predict the development of IA using biomarkers measured before diagnosis.
RESULTS: While no significant differences were observed between IA cases and infected controls, concentrations of 30 inflammatory biomarkers were different between cases and non-infected controls, of which nine were independently replicated: PD-L1, MMP-10, Interleukin(IL)-10, IL-15RA, IL-18, IL-18R1, CDCP1, CCL19 and IL-17C. From the differential abundance analysis of serum samples collected more than 10 days before diagnosis and at diagnosis, increased IL-17C concentrations in IA patients were replicated in the independent cohort.
CONCLUSIONS: An increased circulating concentration of IL-17C was detected both in the discovery and independent cohort, both at the time of diagnosis and in samples 10 days before the diagnosis of IA, suggesting it should be evaluated further as potential (early) biomarker of infection.

BACKGROUND: To date, surgery is the best approach to maximize a cure for symptomatic aspergilloma, but this is not without risk of both morbidity and mortality. The aim of this study is to present the characteristics and outcomes of 77 patients diagnosed with aspergilloma who underwent surgery at Chiang Mai University Hospital (CMUH), and to identify risk factors for composite major postoperative complications (CMPC).
METHODS: This is an observational retrospective cohort study carried out at CMUH over a period of 11 years from January 1, 2010, to February 28, 2021. Patient characteristics and postoperative outcomes were studied. The primary outcomes were categorized into CMPC. Univariable and multivariable risk regression analysis were used to identify risk factors of CMPC, with risk ratio (RR) and 95% confidence intervals being calculated.
RESULTS: There were 77 patients included in this study; 27 patients identified as having CMPC and 55 patients as a non-CMPC group. From the multivariable analysis, a factor associated with CMPC included perioperative FFP transfusion (risk ratio (RR) 1.01,95 % CI 1.01-1.02) and preoperative angiogram embolization (RR 8.42, 95 % CI 1.44-49.06) whereas immediate extubation (RR 0.22, 95% CI 0.06-0.81) was less likely to be associated with CMPC. There was a trend of increased risk of CMPC in patients received perioperative blood transfusion, but the data did not reach statistical significance.
CONCLUSIONS: This study has identified a need for patient profiling before embarking on lung surgery for aspergilloma, to predict outcomes and allocate resources appropriately for safer surgery.

In Ghana, most laboratory diagnoses of severe mycoses are based on histopathology findings due to inadequate availability of serology, culture, and molecular tests. The aim of this study was to evaluate the spectrum of mycoses diagnosed in Ghana. We retrospectively reviewed reports from 2012 to 2021 from three major pathology laboratories in Ghana to identify reports indicating the presence of fungal elements and diagnosis of a mycosis, then extracted demographic, clinical history, site of infection, stain(s), used and diagnosed mycosis details. Over the 10-year period, 107 cases were found. No apparent increasing and decreasing trend in the number of cases per year or in a period was observed. The age range of affected patients was from 4 to 86 years. Special stains for fungi were only used in 22 of 107 (20.6%) of cases. The most frequently affected site was the sino-nasal area (34%). Mycosis type was determined for 58 (54.2%) cases, comprising aspergillosis (21), candidiasis (14), dermatophytosis (6), mucormycosis (3), two cases each of chromoblastomycosis, histoplasmosis, eumycetoma, entomophthoromycosis, sporotrichosis, and Malassezia infection and a single case each of cryptococcosis and deep onychomycosis. Of the 53 (49.5%) cases with presumptive diagnosis data, only seven (13.2%) had a pre-biopsy suspicion of mycosis. There is a wide spectrum of mycoses in Ghana, including endemic mycoses not previously reported. Improving the use of special fungal stains could increase yield and mycoses identification. Laboratory diagnostic capacity needs enhancement to complement histopathology investigations with serology, culture, and molecular methods.
In Ghana, diagnosis of mycoses is mainly based on histopathology findings. To appreciate the varied mycoses diagnosed, we reviewed the reports of major laboratories from 2012 to 2021 and found 107 cases including endemic, rare, and previously unreported cases with fungal stains unusually used.
