ABSTRACT
A feared fungal disease surprised and became a warning to severe cases of COVID-19, especially to health professionals involved with the pandemic. Designated as black fungus for public health services in India, where reported data reflects an increase of more than eighty times the expected increase for Rhizopus among the communities. The disease has become even more worrisome due to the high mortality already established as an opportunistic infection, coupled with the reserved prognosis for all those infected and hospitalised by the SARS-CoV-2 severity criteria. This patient, who was submitted to corticosteroid therapy, in an excessive dose, therefore immunosuppressive, developed a severe, disseminated clinical form. It was verified the progression of the lesions and thus the high risk of trans- surgical lethality, or, also, by the insufficiency of conduct in removing the lesions to their satisfaction. Thus, the therapeutic option is the associated use of micafungin, liposomal amphotericin B and isavuconazole for the regressive phase. The patient remains hospitalised with progressive and discrete improvement. Until the opportunity of reevaluation of the surgery by the interspecialty collaboration.
Uma temida doença fúngica surpreendeu e se tornou um alerta para casos graves de COVID-19, principalmente aos profissionais de saúde envolvidos com a pandemia. Designado como fungo preto para serviços de saúde pública na Índia, onde os dados relatados refletem um aumento de mais de oitenta vezes o aumento esperado para Rhizopus entre as comunidades. A doença tornou-se ainda mais preocupante devido à alta mortalidade já estabelecida como infecção oportunista, aliada ao prognóstico reservado para todos os infectados e internados pelos critérios de gravidade do SARS-CoV-2. Esse paciente, que foi submetido à corticoterapia, em dose excessiva, portanto imunossupressora, desenvolveu uma forma clínica grave e disseminada. Verificou-se a progressão das lesões e, portanto, o alto risco de letalidade transcirúrgica, ou, ainda, pela insuficiência de conduta na remoção das lesões a contento. Assim, a opção terapêutica é o uso associado de micafungina, anfotericina B lipossomal e isavuconazol para a fase regressiva. O paciente permanece internado com melhora progressiva e discreta. Até a oportunidade de reavaliação da cirurgia pela colaboração interespecialista.
ABSTRACT
BACKGROUND: To evaluate HIV infection-induced alterations in the oral mucosa by comparing inflammation, cell maturation, and cytomorphometric changes in oral mucosal cells between HIV-infected patients undergoing highly active antiretroviral therapy (HAART) and non-HIV-infected patients. METHODS: Thirty HIV-infected patients undergoing HAART and 30 non-HIV-infected patients were studied. Four smears were obtained from the lateral border of the tongue and floor of the mouth with a cytobrush. One sample was stained by the Papanicolaou technique, and three samples were processed for Feulgen staining. Papanicolaou-stained smears were analyzed by light microscopy, and the cytoplasmic (CA) and nuclear (NA) area were measured with the Software AxioVision 4.7. RESULTS: The Wilcoxon signed-rank test showed a significant difference in intermediate epithelial cell types between the HIV-infected and non-HIV-infected groups (P=.005). However, this difference was not observed for superficial epithelial cell types with (P=.672) and without a nucleus (P=.069). Comparative analysis revealed no significant difference in CA (P=.604), NA (P=.298) or NA/CA (P=.456) between the HIV-infected and non-HIV-infected groups. Keratohyalin granules were more frequent in the non-HIV-infected group (P=.0001). CONCLUSIONS: The results showed alterations in cell maturation in HIV-infected patients undergoing HAART with undetectable viral load, but no morphometric changes were observed.

BACKGROUND: The genotoxic impact of HIV infection on the oral cavity malignancies is unknown. The aim of this study was to evaluate the effect of HIV infection in micronucleus (MN) frequency on the oral mucosa of HIV+ patients and establish a relationship with early cytogenetic changes in oral carcinogenesis. METHODS: Thirty HIV+ individuals who are under highly active antiretroviral therapy (HAART) and 30 non-HIV patients were evaluated. Two smears were taken from the lateral border of the tongue and mouth floor and stained by Feulgen. The frequency of MN was examined in 3000 cells per subject under common microscopy. RESULTS: MN analysis showed no significant difference between groups by Mann-Whitney U-test for total MNs (P = 0.178). The presence of single MN was greater in control group with statistical significance (P = 0.009), while in HIV group, multiple MNs were exhibited in higher mean. CONCLUSIONS: HIV patients under HAART therapy and low viral load values showed higher frequency of multiple MNs, which, although not statistically significant, may be caused by the action of the Vpr gene, an accessory gene of HIV. These results corroborate the theory of HIV infection cytogenetic damage.

In 2008 isolates of KPC-producing Klebsiella pneumoniae (KPC-KPN) were detected for the first time at Hospital Heliópolis, São Paulo, Brazil. The aim of this study was to characterize the clinical and microbiological outcomes of infections caused by KPC-KPN. A historical cohort of patients from whom KPC-KPN strains were isolated was performed. Isolates were identified as resistant to ertapenem by automated broth microdilution system and screened as carbapenemase producers by the modified Hodge test. The beta-lactamase resistance gene blaKPC was detected by PCR. The genetic relatedness of isolates was determined by PFGE. The study provides early clinical experience in treating KPC-KPN infections in a Brazilian tertiary center.
