A case of severe acute respiratory failure after elective abdominoplasty.

Surgical correction of abdominal muscle diastasis may decrease intra-abdominal volume and increase intra-abdominal pressure. The induced changes may ultimately lead to respiratory compromise. In abdominoplasty, one of the most frequently performed esthetic procedures, those changes are believed to be transient and clinically insignificant.

Intravenous lidocaine infusion in a case of severe COVID-19 infection.

A subset of patients with COVID-19 develops a severe inflammatory response that may lead to respiratory and multiorgan failure. Effective treatment strategies to mitigate or interrupt this self-destructive inflammatory process are limited. The local anesthetic lidocaine has anti-inflammatory properties in addition to its analgesic, antiarrhythmic, and sedating effects that may be beneficial in critically ill COVID-19 patients.

Neutrophil Functions in Immunodeficiency Due to DOCK8 Deficiency.

Neutrophil chemotactic defects have been reported previously in patients with hyper-IgE syndrome. Bi-allelic mutations in dedicator of cytokinesis 8 (DOCK8) gene usually cause an autosomal recessive hyper-IgE syndrome phenotype. Data are lacking about expression of DOCK8 protein in neutrophils or the possible role of DOCK8 in neutrophil function.

Protecting the Brain With Xenon Anesthesia for Neurosurgical Procedures.

Xenon possesses some, but not all, of the clinical features of an ideal anesthetic agent. Besides well-known advantages of rapid awakening, stable hemodynamics and lack of biotransformation, preclinical data lead to the expectation of xenon's advantageous use for settings of acute ongoing brain injury; a single randomized clinical trial using an imaging biomarker for assessing brain injury corroborated xenon's preclinical efficacy in protecting the brain from further injury. In this review, we discuss the mechanisms and hence the putative applications of xenon for brain protection in neurosurgery.

Mutations in STN1 cause Coats plus syndrome and are associated with genomic and telomere defects.

The analysis of individuals with telomere defects may shed light on the delicate interplay of factors controlling genome stability, premature aging, and cancer. We herein describe two Coats plus patients with telomere and genomic defects; both harbor distinct, novel mutations in STN1, a member of the human CTC1-STN1-TEN1 (CST) complex, thus linking this gene for the first time to a human telomeropathy. We characterized the patients' phenotype, recapitulated it in a zebrafish model and rescued cellular and clinical aspects by the ectopic expression of wild-type STN1 or by thalidomide treatment.

Comparative analysis of the behavioral and biomolecular parameters of four mouse strains.

The use of mice as experimental models in pharmacological and biochemical research began over 100 years ago, during which time different mice strains with specific features were developed. Numerous studies demonstrate that the pharmacological efficacy of various compounds significantly varies among different animal strains, a factor which must be considered when analyzing experimental data. The Sabra strain, developed more than 35 years ago, is widely used for research in Israel but has an unclear origin and is not characterized as well as other strains.
