One-Anastomosis Gastric Bypass Versus Roux-en-Y Gastric Bypass as Revisional Surgery After Sleeve Gastrectomy: a Systematic Review and Meta-analysis

The demand for revisional bariatric surgery after sleeve gastrectomy (SG) has increased, but the ideal procedure remains unclear. A systematic review and meta-analysis were performed to compare the outcomes of weight loss and safety of one-anastomosis gastric bypass (OAGB) and Roux-en-Y gastric bypass (RYGB) as revisional procedures for failed SG. Four retrospective comparative studies were included, comprising 499 individuals. Patients submitted to OAGB had a more significant total weight loss (TWL) (MD =  − 5.89%; 95% CI − 6.80 to − 4.97) after revisional surgery. Overall early complication rate was similar between procedures (RD = 0.04; 95% CI: − 0.05 to 0.12). Limited and heterogeneous data prevent meaningful conclusions, but the present analysis suggests that OAGB has a better TWL after revisional surgery.

Transcutaneous spinal direct current stimulation improves locomotor learning in healthy humans

Background

Ambulation is an essential aspect of daily living and is often impaired after brain and spinal cord injuries. Despite the implementation of standard neurorehabilitative care, locomotor recovery is often incomplete.

Anesthetic efficacy of Oraqix? versus Hurricaine? and placebo for pain control during non-surgical periodontal treatment

Objectives: To evaluate the efficacy of Oraqix® during scaling and root planing (SRP) in comparison with 20% benzocaine and placebo. Study Design: 15 patients requiring 4 sessions of SRP were enrolled. For each patient, Oraqix®, Hurricaine®, vaseline or no anesthetic product were randomly assigned each to a quadrant. Treatment pain was evaluated on a 100 mm Visual Analog Scale (VAS) and on a Verbal Rating Scale (VRS). The amount of product administered, the need to re-anesthetise, patient and operator satisfaction and the onset of side-effects were also recorded. Results: Oraqix® was significantly better than nothing, with a reduction of VAS score to 13.3 units, but without significant differences with Vaseline or Hurricaine®. Oraqix® was better in VRS reduction than not using any anesthetic (p=0.001) or using vaseline (p=0.024), but similar to Hurricaine® (p=0.232). Conclusions: Oraqix® effectively controls pain in SRP procedures, with few side-effects and a good acceptance on the part of patients and clinicians. Key words:Controlled clinical trial, topical anesthetic, scaling and root planing.     

Occurrence of two autochthonous cases of American cutaneous leishmaniasis in the neighborhood of Caju,city of Rio de Janeiro,Brazil

American cutaneous leishmaniasis is in full geographic expansion in Brazil and it is considered among the infectious and parasitic diseases of utmost importance worldwide, not only by its frequency, but mainly by therapeutic difficulties, deformities and sequelae that may result. In the state of Rio de Janeiro, the first autochthonous case of American cutaneous leishmaniasis was registered by Rabello in 1913. The authors report two cases of the disease in the region around the Cemetery São Francisco Xavier, in the Caju neighborhood, Rio de Janeiro city, and emphasize the need for actions that aim to early diagnosis and treatment of American cutaneous leishmaniasis cases.
