Familial Renal Glucosuria Presenting as Paroxysmal Glucosuria and Hypercalciuria Due to a Novel SLC5A2 Heterozygous Variant.

Familial renal glucosuria (FRG) is a rare genetic disease characterised by isolated glucosuria in the absence of proximal tubular dysfunction. It usually occurs due to a mutation in the SLC5A2 gene encoding the sodium-glucose cotransporter-2 (SGLT2), responsible for most of the renal glucose reabsorption. We report on a case of a patient presenting with paroxysmal glucosuria and hypercalciuria due to a novel SLC5A2 heterozygous variant. LEARNING POINTS: FRG usually presents with glucosuria but may also be associated with hypercalciuria and aminoaciduria.The amount of glucosuria is variable and can be normal in the same FRG patient because it is influenced by different glycaemia levels. This raises the question of whether the definition of FRG should be broadened to paroxysmal glucosuria.Having glucosuria does not prevent the development of insulin resistance.

Strategies to Prevent Acute Kidney Injury after Pediatric Cardiac Surgery: A Network Meta-Analysis.

BACKGROUND AND OBJECTIVES: AKI is a common complication after pediatric cardiac surgery and has been associated with higher morbidity and mortality. We aimed to compare the efficacy of available pharmacologic and nonpharmacologic strategies to prevent AKI after pediatric cardiac surgery. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: PubMed/MEDLINE, Embase, Cochrane Controlled Trials Register, and reference lists of relevant articles were searched for randomized controlled trials from inception until August 2020. Random effects traditional pairwise, Bayesian network meta-analyses, and trial sequential analyses were performed. RESULTS: Twenty randomized controlled trials including 2339 patients and 11 preventive strategies met the eligibility criteria. No overall significant differences were observed compared with control for corticosteroids, fenoldopam, hydroxyethyl starch, or remote ischemic preconditioning in traditional pairwise meta-analysis. In contrast, trial sequential analysis suggested a 80% relative risk reduction with dexmedetomidine and evidence of <57% relative risk reduction with remote ischemic preconditioning. Nonetheless, the network meta-analysis was unable to demonstrate any significant differences among the examined treatments, including also acetaminophen, aminophylline, levosimendan, milrinone, and normothermic cardiopulmonary bypass. Surface under the cumulative ranking curve probabilities showed that milrinone (76%) was most likely to result in the lowest risk of AKI, followed by dexmedetomidine (70%), levosimendan (70%), aminophylline (59%), normothermic cardiopulmonary bypass (57%), and remote ischemic preconditioning (55%), although all showing important overlap. CONCLUSIONS: Current evidence from randomized controlled trials does not support the efficacy of most strategies to prevent AKI in the pediatric population, apart from limited evidence for dexmedetomidine and remote ischemic preconditioning.

Cardiothoracic robotic assisted surgery in times of COVID-19.

The coronavirus disease 2019 (COVID-19) pandemic poses an immense threat to healthcare systems worldwide. At a time when elective surgeries are being suspended and questions are being raised about how the remaining procedures on COVID-19 positive patients can be performed safely, it is important to consider the potential role of robotic assisted surgery within the current pandemic. Recently, several robotic assisted surgery societies have issued their recommendations. To date, however, no specific recommendations are available for cardiothoracic robotic assisted surgery in COVID-19 positive patients. Here, we discuss the potential risks, benefits, and preventive measures that need to be taken into account when considering robotic assisted surgery for cardiothoracic indications in patients with confirmed COVID-19. It is suggested that robotic assisted surgery might have various advantages such as early recovery after surgery, shorter hospital stay, and reduced loss of blood and fluids as well as smaller incisions. However, electrosurgical and ultrasonic devices, as well as CO2 insufflation should be managed with caution to prevent the risk of aerosolization of viral particles.
