Can We Use the Maximum Phonation Time as a Screening of Pulmonary Forced Vital Capacity in Post-COVID-19 Syndrome Patients?

Objective: To verify the accuracy of the maximum phonation time of the vowel /a/ (MPT/a/), fricative /s/ (MPT/s/), number counting (MPTC), and number reached in this count (CN) to estimate forced vital capacity (FVC) in patients with post-COVID-19 syndrome.

Method: Cross-sectional study involving adult patients, who were admitted to the intensive care unit and referred to the Post-COVID-19 Rehabilitation Outpatient Clinic. Voice function was assessed using a Vocal Handicap Index (VHI) self-assessment questionnaire and MPT tests.

Maximum Phonation Times as Biomarkers of Lung Function.

Purpose: To verify whether measurements of maximal phonation times are biomarkers of forced vital capacity in patients with chronic obstructive pulmonary disease, and to characterize the vocal aspects of these patients, taking into account variables, such as age, body mass index, use of bronchodilators, presence of symptoms, and quality of life related to voice.

Methods: Complete records of 25 subjects with chronic obstructive pulmonary disease, both sexes, aged 31 to 85 years, evaluated by forced vital capacity, maximum phonation times of /a/, and numerical count and number reached at this count, Vocal Symptom Scale, Voice Quality of Life. Data were presented descriptively and statistically analyzed using Student's t test for independent samples and Mann-Whitney U test.

Predictors of Post-COVID-19 Functional Status Scale in Hospitalized Patients Recovering From SARS-CoV-2 Infection.

Objective: The study aimed to investigate whether peripheral and inspiratory muscle strength and architecture, functional capacity, functional mobility, fatigue, and health-related quality of life are predictors of the Post-COVID-19 Functional Status Scale score in patients with post-COVID-19 syndrome who were hospitalized.

Design: A cross-sectional study included 69 patients (53.3 ± 13.

Accuracy of breast magnetic resonance imaging in evaluating the response to neoadjuvant chemotherapy: a study of 310 cases at a cancer center.

Objective: To evaluate the accuracy of magnetic resonance imaging (MRI) of the breasts in the identification of a pathological complete response in patients with breast cancer undergoing neoadjuvant chemotherapy (NAC).

Materials And Methods: This was a single-center, retrospective, observational study designed to validate a diagnostic test. The following variables were evaluated: age; results of the histological and immunohistochemical analysis of the biopsy; post-NAC MRI findings; and results of the histological analysis of the surgical specimen, using the residual cancer burden index.

Impact of breast magnetic resonance imaging on the locoregional staging and management of breast cancer.

Objective: To assess the impact of magnetic resonance imaging (MRI) on the locoregional staging of breast cancer.

Materials And Methods: We evaluated 61 patients with breast cancer who underwent pre-treatment breast MRI, between August 2015 and April 2016. An experienced breast surgeon determined the surgical treatment, on the basis of the findings of conventional imaging examinations, and made a subsequent treatment recommendation based on the MRI findings, then determining whether the MRI changed the approach, as well as whether it had a positive or negative impact on the treatment.

Can diffusion-weighted imaging add information in the evaluation of breast lesions considered suspicious on magnetic resonance imaging?

Objective: To assess the role of diffusion-weighted imaging (DWI) in the evaluation of breast lesions classified as suspicious on magnetic resonance imaging (MRI), correlating the findings with the results of the histological analysis.

Materials And Methods: This was a retrospective, descriptive study based on a review of the medical records of 215 patients who were submitted to MRI with DWI before undergoing biopsy at a cancer center. Apparent diffusion coefficient (ADC) values were calculated for each lesion, and the result of the histological analysis was considered the gold standard.

Role of magnetic resonance imaging in the planning of breast cancer treatment strategies: comparison with conventional imaging techniques.

Objective: To assess the role of magnetic resonance imaging (MRI) in the planning of breast cancer treatment strategies.

Materials And Methods: The study included 160 women diagnosed with breast cancer, who underwent breast MRI for preoperative staging. Using Pearson's correlation coefficient (), we compared the size of the primary tumor, as determined by MRI, by conventional imaging (mammography and ultrasound), and in the pathological examination (gold standard).

Elastographic Evaluation of Indeterminate Breast Masses on Ultrasound.

 To evaluate the diagnostic accuracy of elastography for breast cancer identification in patients with indeterminate lesions on ultrasound.  This prospective, descriptive study included patients with indeterminate breast lesions in the ultrasound and with indication for percutaneous or surgical biopsy. The elastography was evaluated by qualitative analysis and by two methods for the semi quantitative analysis.

Imaging features of idiopathic granulomatous mastitis - Case report.

Idiopathic granulomatous mastitis is a rare disorder of unknown etiology. This disease occurs mostly in young women and often after the lactation period. Women usually present with a fixed, painful mass, sparing the retroareolar region, associated with skin thickening and possible ulceration that mimics carcinoma.

Hyperechoic breast lesions: anatomopathological correlation and differential sonographic diagnosis.

Hyperechoic lesions are not a frequent finding at breasts ultrasonography, and most of times are associated with benign pathologies that do not require further evaluation. However, some neoplasms such as invasive breast carcinomas and metastases may present with hyperechogenicity. Thus, the knowledge about differential diagnoses and identification of signs of lesion aggressiveness are of great relevance to avoid unnecessary procedures or underdiagnosis, and to support the correct clinical/surgical approach.

Lobular Carcinoma in Situ with Atypical Mass Presentation: a Case Report.

Lobular carcinoma in situ (LCIS) is associated with an increased risk of breast cancer and accounts for 1 to 2% of all breast cancers. LCIS diagnosis currently remains one of the major identifiable risk factors for subsequent breast cancer development. Imaging methods are becoming increasingly sensitive, and the consequent detection of small lesions and subtle abnormalities increases the chance of detection of in situ and invasive carcinomas, leading to a reduction in mortality.

Correlation between PET/CT results and histological and immunohistochemical findings in breast carcinomas.

Objective: To correlate the results of (18)F-fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) performed with a specific protocol for assessment of breasts with histological/immunohistochemical findings in breast carcinoma patients.

Materials And Methods: Cross-sectional study with prospective data collection, where patients with biopsy-confirmed breast carcinomas were studied. The patients underwent PET/CT examination in prone position, with a specific protocol for assessment of breasts.

Facial type and head posture of nasal and mouth-breathing children.

Purpose: To verify the facial type and the head posture of nasal and mouth-breathing children from habitual and obstructive etiologies, as well as to correlate the morphological facial index to the head angulation position in the sagittal plane.
