Effectiveness of an inexpensive short-term theoretical-practical course on videosurgery for surgeons in training.

Background: The rapid development of video surgery and minimally invasive surgical techniques prompted many studies on the methods of teaching these techniques to young surgeons in training. However, the characteristics of a short-term course that is both easily accessible and efficient for this group of surgeons remain controversial. To investigate this issue, a short-term training method was proposed for first year surgery residents, using inexpensive handmade wooden simulation boxes with the students smartphones as cameras.

Detrusor underactivity versus bladder outlet obstruction clinical and urodynamic factors.

Objectives: To evaluate the lower urinary tract symptoms, classified by the International Prostate Symptom Score (IPSS), urodynamic results (Watts Factor (WF), Bladder Contractility Index (BCI), and post void residual (PVR), in order to differentiate Detrusor Underactivity (DU) from Bladder Outlet Obstruction (BOO).

Methods: Retrospective observational study performed from 2011 to 2018 at the Hospital das Clínicas of Unicamp. Two phases were done: first, to estimate sample size, and second, to evaluate the predicted parameters.

Analysis of electrocautery generated smoke by chromatographic-mass spectrometry.

Objective: to analyze the chemical components of the smoke from electrocautery from coagulating muscle and liver tissues of pigs.

Methods: we collected smoke produced by electrocautery applied to porcine tissue in previously evacuated bottles, with qualitative and quantitative analysis of the compounds present through the hyphenated technique gas chromatography / mass spectrometry.

Results: there was a majority of decanal aldehyde in the fumes from the subcutaneous, muscle and liver tissues.
