Valentino's Syndrome in the Era of Advanced Imaging and Minimally Invasive Surgery.

Valentino's syndrome is a rare but potentially lethal differential diagnosis for acute appendicitis. We herein present the case of a 22-year-old male patient who presented to the emergency department with acute abdominal pain. Clinical suspicion of acute appendicitis was corroborated by analytical and imaging findings.

Influence of Opacifiers and Different Dentin Thicknesses on the Optical Properties of a Darkened Teeth with Limited Sound Tissue Reduction.

Objective: To evaluate color masking and relative translucency parameter (RTP) of increasing dentin thicknesses from different resin composites, with or without opacifiers, on a veneer dental preparation and resin disks.

Material And Methods: Artificial darkened lateral incisors with 1mm-thick veneers preparations were used to evaluate color masking of different resinous materials, with or without opacifiers: IPS Empress Direct (ED) with or without ED Opaque; and Essentia (ES) with or without ES Masking Liner. For the RTP test; disc-shaped specimens were performed and evaluated with a spectrophotometer (VITA Easyshade) against black and C4 backgrounds.

Genotoxicity analysis of a flame retardant, aluminum diethylphosphinate.

Flame retardants, crucial for fire prevention, are used worldwide, but they are considered to be 'emerging contaminants' and may pose risks to human and environmental health. Aluminum diethyl phosphinate (ALPI) is a halogen-free flame retardant. To evaluate the toxicity of this compound, the following assays were performed: Salmonella/microsome mutagenicity assay; toxicity assays with two endpoints (mitochondrial dehydrogenase activity, plasma membrane integrity); micronucleus assay with human hepatoma cell line HepG2.

Continuous Spinal Anesthesia for Emergent Laparotomy in a Patient With Severe Pulmonary Comorbidities: A Case Report.

Severe pulmonary conditions in patients undergoing surgery place them at greater risk of adverse outcomes. Alternatives to general anesthesia are encouraged, particularly for emergent interventions, as these procedures can compromise the patients' full recovery postoperatively. We describe an example of an underused anesthetic technique, continuous spinal anesthesia, to circumvent the perioperative risk of major abdominal surgery, successfully avoiding invasive mechanical ventilation in these patients.
