Prospective, randomized comparison of the use of FloShield Air System® versus the reference technique (water + povidone-iodine solution) during gynecologic endoscopic surgery to evaluate the operative lens vision quality.

BACKGROUND: The FloShield Air System® is a new device for laparoscopic surgery that utilizes a continuous dry CO2 gas flow over the scope to defog the lens and protect it from condensation, debris and smoke. We set out to compare the performance and efficiency of the device in terms of operative lens vision quality (OLVQ) with the reference technique (water + povidone-iodine (PVI) solution) during gynecologic laparoscopic surgery. MATERIALS AND METHODS: We conducted a single-center randomized prospective study between March and June 2016 (Trials Database Registration NCT02702531) including 53 patients undergoing gynecologic laparoscopic surgery with water + PVI solution and 51 patients who underwent surgical procedures with the FloShield Air System. The primary outcome measure was the number of laparoscope removals during surgery. Secondary outcome measures were the time to clean, assessment of the quality of vision, the correlation between the laparoscopic surgical complexity and outcomes, and cost effectiveness. RESULTS: Overall, the mean patient age was 43.2 years (range 22-86) and body mass index 24.8 (range 16.8-42.7). The mean number of endoscope removals during surgery was 7.0 (range 0-37) in the water + PVI solution arm and 2.8 (range 0-12) in the FloShield Air System® arm. The number of removals was significantly lower in the FloShield arm (p < 0.001). No difference in time to clean, quality of vision, level of laparoscopic procedure complexity, or cost was observed between the groups. CONSLUSIONS: The FloShield Air System® resulted in fewer laparoscopic lens removals than the water + PVI solution solution, but that there was no difference in quality of vision, cleaning time or cost, especially for the more complex surgery.

A case of non-treated Trichomonas vaginalis infection and severe preterm labor with positive obstetrical outcome.

Trichomonas vaginalis is a very common, sexually transmitted, infection that may sometimes be asymptomatic or cause vaginitis and urethritis. Recently, it has been associated with adverse obstetric outcomes such as preterm delivery, low birth weight and premature rupture of membranes. Trichomonas vaginalis can be vertically transmitted at birth. It has been found in pharynx and low respiratory tract of neonates with respiratory disease. It has also been involved in some cases of intellectual disability. The recommended treatment is a 2g metronidazole oral single dose, even for asymptomatic patients. This treatment is effective against Trichomonas and its use is safe during pregnancy. We report here a case of Trichomonas vaginalis infection diagnosed during pregnancy in a patient with severe preterm labor. The patient being allergic to nitroimidazole antibiotics, she did not receive any treatment. She finally gave birth at 34 weeks of gestation (WG) and 5 days, with no other adverse outcome than small prematurity.
