Detection of Oxacillin/Cefoxitin Resistance in Staphylococcus aureus Present in Recurrent Tonsillitis.

BACKGROUND: Recurrent tonsillitis is one of the most common diseases in childhood, caused many times by ß-lactam-resistant S. aureus. The objective of this study was to investigate an alternative method to identify resistance to oxacillin/cefoxitin in S. aureus from hospitalized children with recurrent tonsillitis. METHODS: The samples of S. aureus came from patients with recurrent tonsillitis and were used in 16S rRNA sequencing and an antibiogram test for identification and verifying resistance, after which HSI methodology were applied for separation of S. aureus resistances. RESULTS: The S. aureus isolated showed sensitivity to oxacillin/cefoxitin and the diagnostic images show a visual description of the resistance different groups formed, that may be related to sensitivity and resistance to oxacillin/cefoxitin, characterizing the MRSA S. aureus. CONCLUSIONS: Samples that showed phenotypic resistance to oxacillin/cefoxitin were clearly separated from samples that did not show this resistance. A PLS-DA model predicted the presence of resistance to oxacillin/cefoxitin in S. aureus samples and it was possible to observe the pixels classified as MRSA. The HSI was able to successfully discriminate samples in replicas that were sensitive and resistant, based on the calibration model it received.

In-Hospital Outcomes of Right Minithoracotomy vs. Periareolar Access for Minimally Invasive Video-Assisted Mitral Valve Repair

Abstract Introduction: In minimally invasive mitral valve repair, right minithoracotomy is the most widely performed method, providing a good view of the mitral valve. But regarding other techniques and although it offers limited visualization, the periareolar access is a less traumatic alternative. This study's purpose is to compare in-hospital outcomes in patients who underwent video-assisted minimally invasive mitral valve repair via right minithoracotomy and periareolar access. Methods: This is a retrospective observational study including 37 patients (> 18 years old), without previous right thoracic surgery, who underwent their primary mitral valve repair, with indication for minimally invasive video-assisted approach (via right minithoracotomy or periareolar access), between January 2018 and August 2019. Patients' medical records were consulted to collect demographics data, operative details, and in-hospital outcomes. Results: Twenty-one patients underwent right minithoracotomy, and 16 were operated via periareolar access. The mean patients' age was 62±12 years in the right minithoracotomy group and 61±9 years in the periareolar access group (P=0.2). There are no significant differences in incision length, cardiopulmonary bypass time, aortic cross-clamping time, hematocrit, amount of chest tube drainage, and intensive care unit and in-hospital length of stay. Time to extubation presented significant differences between the right minithoracotomy and the periareolar access group (4.85 hours vs. 5.62 hours, respectively) (P=0.04). Conclusion: In this study, we found similar results in the two applied surgical techniques, except for the time to extubation.

Olfactory dysfunction in the scenario of COVID-19 pandemic in patients screened by the telemonitoring.

OBJECTIVE: To assess the clinical and epidemiological profile of patients with olfactory dysfunction in the scenario of COVID-19 pandemic. METHODS: The study selected patients with loss of smell, previously screened by telemonitoring system of the Municipal Health Department of Goiânia (GO), Brazil, who agreed to answer a questionnaire about COVID-19 symptoms and findings of exams. The interviews were conducted by six otolaryngologists, who applied the specific questionnaire, over the phone. RESULTS: A total of 13,910 patients underwent telemonitoring, and 627 (4.51%) had olfactory loss complaints. Out of them, 330 were included in the survey. We observed a higher prevalence of altered smell in women (67%), and in patients aged under 50 years (86%). In most cases the manifestations had a sudden onset (70%), and in the first 5 days of illness (80%). The most prevalent associated symptom was a change in taste (89%), and only 2.7% of interviewed patients required hospitalization. CONCLUSION: Anosmia in COVID-19 is more prevalent in females and individuals aged under 50 years. It is a relevant initial symptom predictive of the disease, together with dysgeusia.

RESUMO Objetivo Avaliar o perfil clínico-epidemiológico dos pacientes com distúrbios olfatórios no cenário de pandemia da COVID-19. Métodos Foram selecionados pacientes com queixa de perda de olfato, previamente triados pelo sistema de telemonitoramento da Secretaria Municipal de Saúde de Goiânia (GO), Brasil, que concordaram em responder um questionário sobre sintomas e achados de exame em relação à COVID-19. As entrevistas foram realizadas por seis médicos otorrinolaringologistas que, via telefonema, submeteram os participantes a questionário específico. Resultados Dos 13.910 pacientes em telemonitoramento, 627 (4,51%) apresentavam queixas de alteração do olfato, e, destes, 330 foram incluídos na pesquisa. A maior prevalência de alteração do olfato se deu em mulheres (67%), e em pacientes com menos de 50 anos (86%). Na maioria dos casos, as manifestações ocorreram de forma súbita (70%), e nos primeiros 5 dias de doença (80%). O sintoma associado mais prevalente foi alteração do paladar (89%), e houve necessidade de internação hospitalar somente em 2,7% dos pacientes entrevistados. Conclusão A anosmia na COVID-19 é mais prevalente no sexo feminino e em pacientes com menos de 50 anos. Juntamente da disgeusia, trata-se de importante sintoma inicial preditivo da doença.

Evaluation of the raw water quality: physicochemical and toxicological approaches.

Environmental degradation has increased, mainly as a result of anthropogenic effects arising from population, industrial and agricultural growth. Water pollution is a problem that affects health, safety and welfare of the whole biota which shares the same environment. In Goiânia and metropolitan region, the main water body is the Meia Ponte River that is used for the abstraction of water, disposal of treated wastewater and effluents. In addition, this river receives wastewater from urban and rural areas. The aim in this present study was to evaluate the quality of raw water by some physical, chemical and toxicological tests. The physicochemical results found high levels of turbidity, conductivity, aluminum, phosphorus and metal iron, manganese, copper and lithium when compared to the standards of the Brazilian legislation. The values found of toxicity demonstrated a high degree of cytotoxicity and genotoxicity. Therefore, it was concluded that the Meia Ponte River has been undergoing constant environmental degradation, causing the poor quality of its waters. Thus, measures for the prevention and recovery should be adopted for the maintenance of the Meia Ponte River.
