Article Synopsis
  • * Using samples from 78 RCC patients, the study compared tumor tissue to adjacent healthy tissue, finding low mitochondrial DNA and protein levels in ccRCC tumors while observing changes in mitochondrial content and function linked to tumor grade.
  • * The results indicate that as ccRCC severity increases, CII function declines, which could help doctors categorize patients by prognosis and explore targeted therapies.

Purpose: This study aimed to propose a radiological classification of the incudo-stapedial angle by preoperative high-resolution computed tomography (HRCT) images and to highlight its importance for predicting the use of reversal-steps stapedotomy (RSS) rather than the traditional non-reversal technique.

Methods: We included 83 candidates for stapedotomy operation. Two physicians measured the radiological incudo-stapedial joint angle in the preoperative HRCT.

Background: Totally-implantable active middle ear devices (AMED) rely on a non-rechargeable battery encased with the implantable sound processor that needs to be replaced with a minor surgical procedure after its depletion.

Objectives: This study aimed to investigate the most significant factors affecting the implant's battery life.

Materials And Methods: The implanted subjects (29 patients) were divided into three groups; group A with 17 patients who underwent one battery change surgery; group B with ten patients who underwent two battery changes; and group C with two patients and three surgeries.

Background: This study aimed to analyze the behavior of acute invasive fungal rhinosinusitis (AIFRS) associated with COVID-19 infection as there has been an increase in the rate of AIFRS cases in the last two years, and many reports connected this rising with the COVID-19 infection. We studied most factors that may impact the prognosis as a trial to find the most affecting factors to improve the outcomes.

Methods: It was a retrospective observational study that included cases from four tertiary referral institutions between November 2020 to February 2022.

Background: Non-echo planar (EPI) diffusion-weighted (DW) MRI has become an effective tool for the follow-up after cholesteatoma surgery and decreased the rate of second-look surgeries.

Objectives: To shed light on the optimal imaging follow-up protocol to detect postoperative residual or recurrent cholesteatoma.

Materials And Methods: 64 patients were included in this prospective study.

Background: Thulium laser use in stapedotomy surgery is usually associated with many doubts regarding the thermal effect on the vestibular area and the production of acoustic shock waves, which may result in permanent complications.

Objectives: We aimed to evaluate the efficacy and safety of the Thulium laser use in stapedotomy and its long-term effects on the clinical and audiological results.

Material And Methods: It was a retrospective randomized case-series study.

Objective: Middle ear cholesteatoma may lead to the erosion of the bony structures of the temporal bone, possibly causing intra- and extracranial complications. Surgical treatment is mandatory, and due to possible residual/recurrent disease, the use of reliable diagnostic methods is essential. Our study aimed to evaluate the reliability of non-EPI DW-MRI for the follow-up of cholesteatoma after surgery.

Cholesteatomas are frequent middle ear benign tumors of unknown etiology. Infectious agents have been considered as possible contributing factors in the pathogenesis of cholesteatomas. Aiming to investigate the presence of respiratory viruses in primary cholesteatoma tissues, 26 formalin-fixed paraffin-embedded primary cholesteatoma tissues obtained from patients seen at the of the Clinical Hospital of the University of São Paulo School of Medicine, in Ribeirão Preto, Brazil were tested by real-time polymerase chain reaction (PCR).

Background: Respiratory Syncytial Virus (RSV) is the main cause of pediatric morbidity and mortality. The complex evolution of RSV creates a need for worldwide surveillance, which may assist in the understanding of multiple viral aspects.

Objectives: This study aimed to investigate RSV features under the Brazilian Influenza Surveillance Program, evaluating the role of viral load and genetic diversity in disease severity and the influence of climatic factors in viral seasonality.

Background: The high-risk human papillomavirus (HR-HPV) infection is the main cause of cervical cancer development, and the most common types were included in the last approved nonavalent vaccine (9vHPV). Geographical, socioeconomic and ethnic barriers in developing countries challenge primary and secondary prevention measures of cervical cancer. We aimed to determine the prevalence of HPV infection and the viral load of HR-HPV 9vHPV-related types black women resident in rural semi-isolated communities.

Laryngeal aspergillosis is most commonly seen as a secondary infection that spreads from the lungs and tracheobronchial tree. Primary invasive aspergillosis of the larynx is rare and most likely seen in an immunocompromised patient. We present a case of a 59-year-old woman who presented with progressive dysphonia and subsequently acute stridor.

Background: This study describes the investigation of an outbreak of diarrhea, hemorrhagic colitis (HC), and hemolytic uremic syndrome (HUS) at a daycare center in southeastern Brazil, involving fourteen children, six staff members, six family members, and one nurse. All bacterial and viral pathogens detected were genetically characterized.

Results: Two isolates of a strain of enterohemorrhagic Escherichia coli (EHEC) serotype O111:H8 were recovered, one implicated in a case of HUS and the other in a case of uncomplicated diarrhea.

The course of differentiation of pluripotent stem cells into cardiomyocytes and the intermediate cell types are characterized using molecular markers for different stages of development. These markers have been selected primarily from studies in the mouse and from a limited number of human studies. However, it is not clear how well mouse cardiogenesis compares with human cardiogenesis at the molecular level.

Background: Noroviruses are the major cause of gastroenteritis outbreaks worldwide in all age groups. The several genotypes, mutation, and recombination events guarantee the broad diffusion and maintenance of these viruses in the general human population. We described an outbreak caused by a norovirus recombinant strain screened in samples obtained from children and hospital staff affected in an outbreak of diarrhea at neonatal and pediatric intensive care units in Southeastern Brazil.

Background: Cervical cancer screening might contribute to the prevention of anal cancer in women. We aimed to investigate if routine cervical cancer screening results-namely high-risk human papillomavirus (HPV) infection and cytohistopathology-predict anal HPV16 infection, anal high-grade squamous intraepithelial lesions (HSIL) and, hence, anal cancer.

Methods: We did a systematic review of MEDLINE, Embase, and the Cochrane library for studies of cervical determinants of anal HPV and HSIL published up to Aug 31, 2018.
