There are few reports of serious fungal infections in Nepal though the pathogenic and allergenic fungi including Aspergillus species are common in the atmosphere. Herein, we estimate the burden of serious fungal infections in Nepal. All published papers reporting fungal infection rates from Nepal were identified. ⋯ Cases of oral and oesophageal candidiasis in HIV/AIDS patients were estimated at 10,347 and 2950, respectively. There is a significant burden of serious fungal infections in Nepal. Epidemiological studies are necessary to validate these estimates.

Serious fungal infections (SFIs) could be more frequent than are recognised. Estimates of the incidence and prevalence of SFIs are essential in order to identify public health problems. We estimated the rates of SFIs in Mexico, following a methodology similar to that used in prior studies. ⋯ Most are associated with high morbidity and mortality rates. Validation of these estimates with epidemiological studies is required. The burdens indicate that an urgent need to improve medical skills, surveillance, diagnosis, and management of SFIs exists.

We evaluated the performance of the Aspergillus-specific lateral-flow device (LFD) test for diagnosing invasive pulmonary aspergillosis (IPA) in patients with underlying haematological malignancies. Participating centres were the two Austrian University Hospitals of Graz and Innsbruck. LFD performance was evaluated with 95 bronchoalveolar lavage fluid (BALF) samples from 72 patients collected prospectively in Graz, and with 24 BALF bio bank samples from 23 patients (21 samples with probable IPA) in Innsbruck. ⋯ Sensitivity of the BALF-LFD test for probable IPA was 57% in Innsbruck bio bank samples. Our results indicate that the BALF-LFD-test provides fast results with moderate sensitivities in patients with underlying haematological malignancies. Similar to other diagnostic tests and biomarkers sensitivity of the test may be influenced by ongoing systemic mould-active treatment.

Sporotrichosis has emerged as the main subcutaneous mycosis of humans and animals around the world. With particular differences in frequency, the major species includes Sporothrix brasiliensis, S. schenckii, S. globosa and S. luriei. In Brazil, the main aspect of this epidemic is based on the zoonotic transmission through the scratches and bites of diseased cats contaminated with S. brasiliensis. ⋯ Sporothrix brasiliensis was the agent in the feline-transmitted cases. Sporothrix globosa was isolated from a patient with fixed cutaneous lesions that did not report any contact with diseased animals. In conclusion, beyond the borders of Rio de Janeiro epidemic, agents of sporotrichosis in Espírito Santo show a scattered occurrence with high species diversity.

At the University Hospital of Cologne, in general two patient groups at high risk for invasive aspergillosis receive posaconazole prophylaxis: Acute myelogenous leukaemia patients during remission induction chemotherapy and allogeneic haematopoietic stem cell transplant recipients. Other patients at risk undergo serum galactomannan testing three times weekly. At 72-96 h of persisting fever despite broad-spectrum antibiotics, or at onset of lower respiratory tract symptoms a thoracic computed tomography (CT) scan is performed. ⋯ If the diagnosis of IPA is not established, mucormycosis is a valid concern. In patients with breakthrough IPA during posaconazole prophylaxis liposomal amphotericin B is the drug of choice. If no posaconazole prophylaxis was given, voriconazole is the treatment of choice for IPA.
