Association between bacterial resistance profile and the development of intra-abdominal abscesses in pediatric patients with perforated appendicitis: cohort study.

Purpose: The objective of this study was to determine the association between the presence of a microorganism resistant to the antibiotic used in empirical therapy and the development of intra-abdominal abscesses in children with perforated appendicitis.

Methods: A prospective cohort study was conducted in patients under 18 years of age who underwent laparoscopic appendectomy between November 1, 2019, and September 30, 2020, in whom perforated appendicitis was documented intraoperatively. Peritoneal fluid samples were taken for bacteria culture purposes, and clinical and microbiological data were collected from all patients.

Presurgical time and associated factors as predictors of acute perforated appendicitis: a prospective cohort study in a teaching pediatric hospital in Colombia.

Background: We aim to determine the association between out and in-hospital factors with time, from the beginning of the symptoms to the surgery, in patients with acute appendicitis treated at Fundación Hospital Pediatrico La Misericordia (HOMI) in Colombia.

Methods: Eleven month prospective cohort study of pediatric patients at HOMI with acute appendicitis diagnosis taken to surgery. Data from the out-of-hospital phase was collected by surveying parents, and the data regarding the in-hospital phase was completed with medical records.

Accelerated fatigue resistance of novel-design histoanatomic implant restorations made of CAD/CAM bilaminar assemblies.

Objectives: Evaluate the fatigue resistance and failure mode of novel-design implant restorations made of histoanatomic computer-assisted design/computer-assisted manufacturing (CAD/CAM) bilaminar bonded assemblies.

Material And Methods: 60 screw-retained implant restorations were fabricated. Monolithic restorations were used as a control group (15 lithium disilicate: group CE; and 15 nanofilled composite resin: group CL), and compared with bilaminar restorations (15 dentin-shaped lithium disilicate mesostructures with a bonded nanofilled composite resin veneer: group CEL; and 15 dentin-shaped nanofilled composite resin mesostructures with a bonded lithium disilicate veneer: group CLE).

Partial-prep bonded restorations in the anterior dentition: Long-term gingival health and predictability. A case report.

Bonded porcelain restorations are a predictable and durable treatment option that can restore not only the strength and function of the teeth but also the esthetic appearance. One important issue in adhesive dentistry is the preservation of sound enamel. Following biomimetic principles, employing minimally invasive applications and adhesive technologies is of paramount importance for successful restorations.
