[Utility of mouth rinses with povidone-iodine and hydrogen peroxide in patients with COVID-19]. / Utilidad de los enjuagues con povidona yodada y peróxido de hidrógeno en pacientes con COVID-19.

Introduction: Povidone-iodine and hydrogen peroxide could be effective in against SARS-CoV-2. Methods: A "non-interventional trial" in 88 patients (43 ± 17 yrs, 55% men) with SARS-CoV-2 in nasopharyngeal swabs (RT-PCR). 31 received mouth rinses/gargling with povidone-iodine (every 8 h, two consecutive days), 17 with mouth rinses/gargling of hydrogen peroxide, and 40 controls. PCR were repeated at 3, 11 and 17 days. Results: After intervention the viral load (Log 10 copies/ml) remained similar in povidone-iodine (4.3 ± 2.7 copies/ml), hydrogen peroxide (4.6 ± 2.9 copies/ml; p = 0.40) and controls (4.4 ± 3.0 copies/ml). The percentage of patients with a negative result in the second PCR was 27% in povidone-iodine group, 23% in hydrogen peroxide and 32% in controls; in the third PCR, 62%, 54% and 58% respectively; and in the fourth PCR, 81%, 75% and 81%. Conclusion: Our results do not support the clinical usefulness of mouth rinses/gargling with povidone-iodine or hydrogen peroxide in patients with COVID-19.

Unusual Splitting of Medial Cord of the Right Brachial Plexus and Its Relation to the Axillary Artery and Subscapular Artery: A Case Report.

BACKGROUND: Variations in human anatomy have been associated with numerous clinical correlations that may affect patient care. In this article, we present a unique variation of the medial cord of the brachial plexus about the axillary artery and subscapular artery. The precise assessment of this unique morphology was performed during a cadaveric dissection. CASE PRESENTATION: Contrary to the general course of the medial cord of the brachial plexus, this report demonstrates a rare splitting of the medial cord around the axillary artery and a second abnormal communication between the posterior and medial cords that show a "nutcracker-like" syndrome involving the subscapular artery. CONCLUSION: Such variations could make surgeries challenging. We also infer that these anatomical variations could make gliding therapy inefficient in any motor dysfunction initiating from the brachial plexus.

A Unique Communicating Arterial Branch between the Celiac Trunk and the Superior Mesenteric Artery: A Case Report.

BACKGROUND: Many anatomical variations have been associated with the Celiac Trunk, of which most are classified as being asymptomatic. CASE PRESENTATION: In this article, we describe yet another anatomical variation involving the Celiac Trunk, Superior Mesenteric artery and the Inferior Pancreaticoduodenal Artery during routine cadaveric dissection. We identified a fourth branch of the Celiac trunk (quadrification) that communicated with the Superior Mesenteric artery at the point of origin of the Inferior Pancreaticoduodenal artery which we concluded to be the Anterior Inferior Pancreaticoduodenal artery. CONCLUSION: This anastomosis could be essential in the case of occlusion between the Celiac Trunk and the Superior Mesenteric artery.
