High Fatality Rates in Pediatric Multisystem Inflammatory Syndrome: A Multicenter Experience From the Epicenter of Brazil's Coronavirus Pandemic.

Background: Brazil´s case fatality rate (CFR) of pediatric multisystem inflammatory syndrome in children and adolescents (MIS-C) is among the highest worldwide. Despite these concerns, limited hospital-based and comprehensive pediatric data have been published on MIS-C in Brazilian children.

Methods: We performed a descriptive analysis of the MIS-C scores in 16 public and private hospitals providing secondary and tertiary care in the metropolitan area of São Paulo, Brazil.

Abdominal esophagocardiectomy with esophagogastric anastomosis, with vagal preservation and construction of a spiral anti reflux valve in the treatment of advanced megaesophagus.

Objective: present a new operative technique characterized by abdominal esophagocardiectomy, with esophagogastrus anastomosis, vagal preservation and spiral anti-reflux valve construction in the treatment of advanced megaesophagus in patients with severe systemic diseases, as well as its result in an initial group of 17 patients.

Method: We selected 17 patients with advanced megaesophagus and comorbidities submitted to new technique. The following parameters were analyzed: age, sex, length of hospital stay, early and late complications, mortality, radiological/endoscopic aspects.

COVID-19 diagnosis in a patient with critical limb ischemia: complications and clinical outcomes.

A 67-year-old male diabetic patient with systemic arterial hypertension was admitted to the emergency department with a necrotic ulcer in the left external malleolus and no palpable popliteal or pedal pulses. Arterial Duplex ultrasound identified femoropopliteal occlusion, with popliteal refilling below the knee and a patent peroneal artery. An endovascular procedure was performed, requiring retrograde access to the popliteal artery to re-establish blood flow and deploy a popliteal stent.

Surgical Management of Palatal Pleomorphic Adenoma (PPA) Recurrence After 10 years, Treated at a Brazilian Center - A Case Report.

Pleomorphic adenoma, considered the most frequent benign mixed neoplasm of the minor salivary glands, occurs mainly in the region of the hard palate, with slight predilection in females and peak of incidence between the third and fifth decades of life. An increase in recurrence rates has been associated with the histopathological variants of the tumor, cellular characteristics, stroma, and capsule rupture during surgical removal of the lesion. The present case report aims to describe the surgical approach performed on the patient, a 45-year-old woman with a recurrent Pleomorphic Adenoma (PA) in the region of the hard palate on the right side, 10 years after initial enucleation of the lesion; her main complaint was an increase in volume in the palatal region.

Retention systems for extraoral maxillofacial prosthetic implants: a critical review.

We describe the techniques available for retention of implant-supported prostheses: bar-clips, O-rings, and magnets. We present reported preferences and, although this is limited by the heterogeneity of methods used and patients studied, we hope we have identified the best retention systems for maxillofacial prosthetic implants. If practitioners know the advantages and disadvantages of each system, they can choose the most natural and comfortable prosthesis.

A duplex scan-based morphologic study of the femoral vein: incidence and patterns of duplication.

The presence of femoral vein (FV) duplicity has potential influence in the misdiagnosis of deep vein thrombosis. Also, FVs are suitable vascular substitutes, especially in the substitution of infected prosthetic grafts. The objective of this study was to describe the prevalence, anatomic patterns and characteristics of FV duplicity in adult individuals by duplex scan examination.

Comparison of common carotid artery intima-media thickness between Brazilian Euro-descendants and Afro-descendants with atherosclerosis risk factors.

Objective: To compare common carotid intima-media thickness (IMT) between the two major Brazilian ethnic groups (those of African descent and those of European descent) among individuals with one or more risk factors for atherosclerotic disease.

Method: Two hundred and six patients with one or more risk factors for atherosclerotic disease were evaluated in a cross-sectional study in which their clinical, ethnic and Demographic characteristics were collected. All patients underwent duplex ultrasound examination of their carotid vessels to obtain IMT measurements.

A practical protocol to measure common carotid artery intima-media thickness.

Objective: To describe and test a practical protocol to measure common carotid intima-media thickness that uses the combined values of two longitudinal examination angles to increase sensitivity.

Method: Between February and September 2005, 206 patients underwent duplex scan examination of carotid vessels, and the intima-media thickness of 407 common carotids were measured in three angles: transversal, longitudinal posterolateral, and anterolateral, with three intima-media thickness measurements for each near and far wall. In addition to numbers obtained from the three angles of measurement, a fourth visual perspective was obtained by combining the intima-media thickness results of posterolateral and anterolateral longitudinal views and considering the thickest wall measurement.

Incidence and risk factors for bilateral deep venous thrombosis of the lower limbs.

The incidence of bilateral deep venous thrombosis in patients with single limb or bilateral symptoms was determined using duplex scan examination. In a prospective study, 157 inpatients with clinical suspicion of deep venous thrombosis underwent duplex scan evaluation of the lower extremities. Demographic characteristics, physical examination data, and risk factor information were collected.
