Bivalvular Endocarditis Due to Polymicrobial Coinfection with and : A Case Report and Review of the Literature.

Polymicrobial endocarditis is uncommon, and polymicrobial endocarditis in combination with is very rare. We herein describe an extremely rare case of polymicrobial bivalvular endocarditis due to coinfection with and in a 62-year-old male patient, and extensively review the relevant medical literature. To the best of our knowledge, only three similar cases have been previously reported.

Response Rate of the Third and Fourth Doses of the BNT162b2 Vaccine Administered to Cancer Patients Undergoing Active Anti-Neoplastic Treatments.

The BNT162b2 vaccine is globally used for preventing morbidity and mortality related to COVID-19. Cancer patients have had priority for receiving the vaccine due to their diminished immunity. This study reports the response rate of administering the third and fourth vaccine doses to cancer patients receiving active anti-neoplastic treatment.

Performance of low-dose cosyntropin stimulation test in the afternoon.

Background: Earlier research on 1 μg low-dose test (LDT) performed using 20.3 cm plastic IV tubing on healthy volunteers, has shown that afternoon testing was associated with a sevenfold increased likelihood of failing the test. Nevertheless, it has been claimed that subnormal cortisol response using plastic tubes might have resulted from cosyntropin adherence to the tube and, thus, loss of the delivered dosage.

Performance of low-dose cosyntropin stimulation test handled via plastic tube.

Purpose: Studies on 1 μg low-dose test showed that among 1 μg cosyntropin samples pushed through long IV plastic tubing, some adrenocorticotropic hormone dosage was not recovered, and in healthy volunteers it provided subnormal cortisol responses. The aim of the current study is to assess whether there is any loss in adrenocorticotropic hormone 1-24 concentration when pushed through a short plastic tube, and to assess serum and salivary cortisol responses in low-dose test among healthy volunteers, using a similar short plastic tube vs. direct intravenous consyntropin injection.

Use of three-dimensional fluoroscopy to determine intra-articular screw penetration in proximal humeral fracture model.

Background: Proximal humeral locking plates have significantly improved the treatment of proximal humeral fractures in recent years; however, they are not devoid of complications. Inadvertent screw penetration into the joint is a well-documented complication. Intraoperative 3-dimensional (3D) imaging may assist in detecting intra-articular implant penetration.
