Temporomandibular joint ankylosis cases serve as a challenge for both surgeons and anesthesiologists possibly due to the unavailability of resources in remote locations. Distressing issues brought on by its ankylosis include functional as well as esthetic issues such as considerable difficulties in managing the airway, especially in children because of the physiology and structure of their airways being different. Fiberoptic bronchoscopy (FOB) has a well-established role in patients with difficult airways, but it is especially challenging in pediatric patients because of their lack of cooperation and diminished lung reserve...

Sustained Notch2 signals induce trans-differentiation of Follicular B (FoB) cells into Marginal Zone B (MZB) cells in mice, but the physiology underlying this differentiation pathway is still elusive. Here, we demonstrate that most B cells receive a basal Notch signal, which is intensified in pre-MZB and MZB cells. Ablation or constitutive activation of Notch2 upon T-cell-dependent immunization reveals an interplay between antigen-induced activation and Notch2 signaling, in which FoB cells that turn off Notch2 signaling enter germinal centers (GC), while high Notch2 signaling leads to generation of MZB cells or to initiation of plasmablast differentiation...

PURPOSE: A suitable option for severe obesity treatment is a surgical approach. After surgery, metabolic markers and weight frequently return to adequate values; however, concerning systemic inflammatory mediators, the results are inconsistent. Furthermore, it has been suggested that leucocyte function may be affected even after weight normalization. This study aimed to determine if the surgical treatment of obesity influences the production of cytokines by LPS-stimulated as a function of leucocytes...

BACKGROUND: Associations between the WNT5A rs566926 variant and non-syndromic orofacial cleft (NSOC) have been reported in different populations. OBJECTIVE: This study aimed to investigate the role of the rs566926 single nucleotide polymorphism (SNP) in WNT5A and its interactions with SNPs in BMP4, FGFR1, GREM1, MMP2, and WNT3 in the occurrence of NSOC in a Brazilian population. METHODOLOGY: A case-control genetic association study was carried out involving participants from four regions of Brazil, totaling 801 patients with non-syndromic cleft lip with or without cleft palate (NSCL±P), 273 patients with cleft palate only (NSCPO), and 881 health volunteers without any congenital condition (control)...

INTRODUCTION: Haemoptysis can be a feature of lung cancer and patients are typically fast-tracked for evaluation with chest radiography, contrast-enhanced CT and fibreoptic bronchoscopy (FOB). OBJECTIVE: We aim to explore whether FOB should be conducted as a component of the routine evaluation of non-massive haemoptysis, especially in the context of suspected lung cancer. METHODS: MEDLINE, EMBASE and Cochrane Library were searched for studies comparing FOB with CT in the evaluation of non-massive haemoptysis while reporting at least one of the listed primary outcomes...

OBJECTIVES: This study aimed to analyze the cost-effectiveness of whitening toothpastes and at-home bleaching for the treatment of tooth discoloration. METHODOLOGY: A cost-effectiveness economic analysis was conducted, and eight randomized clinical trials were selected based on the whitening agent product used: blue covarine dentifrices (BCD), hydrogen peroxide dentifrices (HPD), dentifrices without bleaching agents (CD, negative control), and 10% carbamide peroxide (CP10, positive control) for at-home bleaching...

"Mucopolysaccharidosis" (MPS) is a rare, autosomal recessive lysosomal storage disease characterized by deficiencies in 11 different lysosomal enzymes involved in the metabolism of glycosaminoglycans (GAGs) leading to its accumulation, the condition which results in anatomic abnormalities and multi-organ dysfunction that increases the risk of anesthesia complications. The patterns of accumulation form the basis of MPS classification into seven types of progressive diseases. Most of the MPS types have facial and oral characteristics that increase the risk of airway management...
