- Ultrasonography in the Assessment of Tumors of the Cheek: Water Mouth Distension Technique(2023) CHAMMAS, Maria Crisitna; TAKAHASHI, Marcelo Straus; MOYSES, Raquel Ajub; POMPEIA, Celine; TAVARES, Marcos Roberto; CERRI, Giovanni GuidoPurpose To describe a new B-mode ultrasound examination technique to assess cheek tumors. Materials and Methods 30 cheek oral cavity lesions of different histological types (11 benign and 19 malignant) from 23 patients (11 women and 12 men, 7-82 years old, mean age of 49.5 years) were analyzed. Transcutaneous oral B-mode ultrasound (5-12 MHz transducer) was carried out in two stages. Initially it was performed conventionally with an empty mouth. Next, the patient was asked to keep their oral cavity filled with water (like when using a mouthwash) during imaging for the new test examination technique. The anatomical layers of this region and the characteristics of the tumors were evaluated. Lesions were classified as ill defined, partially defined, or defined. Conventional findings were compared to those of the new technique using the Wilcoxon signed-rank test. Ultrasound results were compared to histological findings analyzed by an independent team. Results The conventional empty mouth technique was able to confidently define lesion extension in only 6 of the 30 lesions, while the water-filled mouth technique was able to confidently define lesion extension in 29 of the 30 lesions (p<0.00001). Conclusion We present a novel technique that dramatically improves ultrasound staging of cheek oral cavity tumors. In addition to the increase in ultrasound accuracy, this technique does not require any special equipment or extra cost, is very well tolerated by patients, and thus should be considered in the evaluation of every patient undergoing transcutaneous cheek ultrasound for oral cavity lesion characterization.

- Brain glucose metabolism and gray matter volume in retired professional soccer players: a cross-sectional [F-18]FDG-PET/MRI study(2023) ARANHA, Mateus Rozalem; COUTINHO, Artur Martins; CARNEIRO, Camila de Godoi; PASTORELLO, Bruno Fraccini; STUDART-NETO, Adalberto; GUARIGLIA, Carla Cristina; TSUNEMI, Miriam Harumi; MOREIRA, Everton Luis Santos; IANOF, Jessica Natuline; ANGHINAH, Renato; NITRINI, Ricardo; CERRI, Giovanni Guido; FORTEA, Juan; BUCHPIGUEL, Carlos Alberto; LEITE, Claudia CostaBackground Professional soccer athletes are exposed to repetitive head impacts and are at risk of developing chronic traumatic encephalopathy. Objective To evaluate regional brain glucose metabolism (rBGM) and gray matter (GM) volume in retired soccer players (RSPs). Methods Male RSPs and age and sex-matched controls prospectively enrolled between 2017 and 2019 underwent neurological and neuropsychological evaluations, brain MRI and [F-18]FDG-PET in a 3.0-Tesla PET/MRI scanner. Visual analysis was performed by a blinded neuroradiologist and a blinded nuclear physician. Regional brain glucose metabolism and GM volume were assessed using SPM8 software. Groups were compared using appropriate statistical tests available at SPM8 and R. Results Nineteen RSPs (median [IQR]: 62 [50-64.5] years old) and 20 controls (60 [48-73] years old) were included. Retired soccer players performed worse on mini-mental state examination, digit span, clock drawing, phonemic and semantic verbal fluency tests, and had reduced rBGM in the left temporal pole (pFDR = 0.008) and the anterior left middle temporal gyrus (pFDR = 0.043). Semantic verbal fluency correlated with rBGM in the right hippocampus, left temporal pole, and posterior left middle temporal gyrus (p <= 0.042). Gray matter volume reduction was observed in similar anatomic regions but was less extensive and did not survive correction for multiple comparisons (pFDR >= 0.085). Individual [18F]FDG-PET visual analysis revealed seven RSPs with overt hypometabolism in the medial and lateral temporal lobes, frontal lobes, and temporoparietal regions. Retired soccer players had a higher prevalence of septum pellucidum abnormalities on MRI. Conclusion Retired soccer players had reduced rBGM and GM volume in the temporal lobes and septum pellucidum abnormalities, findings possibly related to repetitive head impacts.
- Telemedicine in Brazil: Teleconsultations at the Largest University Hospital in the Country(2023) SCUDELLER, Paula Gobi; PEREIRA, Antonio Jose; CERRI, Giovanni Guido; JATENE, Fabio Biscegli; BEGO, Marco; AMARAL, Talita Freitas; GARCIA, Michelle Louvaes; LAMAS, Celina Almeida; ALVARENGA, Aline Morgan; GUTIERREZ, Marco Antonio; COBELLO JUNIOR, Vilson; CARVALHO, Carlos Roberto Ribeiro de; Teleconsultation HCFMUSP Study GrpThe coronavirus disease (COVID-19) pandemic leveraged telemedicine worldwide mainly due to the need for social distancing, patient safety, and infection prevention. The Hospital das Clinicas da Faculdade de Medicina da Universidade de Sao Paulo (HCFMUSP) was a key reference site in the treatment of COVID-19 severe cases in the country. To continue patient's health care, it became necessary to increase the number of teleconsultations and standardize it institutionally. Herein, we briefly described how the HCFMUSP improved the teleconsultation health care service during the COVID-19 pandemic, highlighting the implementation of important innovations and the throughout standardization process, including patients and professional workflow. We also detailed the methodology used to implement or improve teleconsultation in a medical/multidisciplinary specialty at HCFMUSP. All these efforts made the HCFMUSP reach the goal of converting 15% of all face-to-face consultations into teleconsultations only in 2021. In addition, there were more than 370,000 teleconsultations until the end of 2022. Our experience has shown that having a supporting team, a digital certification process, and the data integration were key factors toward the successful implementation of the teleconsultation services. We believe that progressing toward teleconsultation will improve the population covered by health care services in Brazil, as well as contribute to a reduction of waiting time, and solving costs to health care institutions and patients. We expect this report of our experience in teleconsultation implementation could inspire and guide other health care institutions in the development of telemedicine.
