ASSESSMENT OF WEIGHT LOSS AFTER NON-ADJUSTABLE AND ADJUSTABLE INTRAGASTRIC BALLOON USE.

Background: Intragastric balloon (IGB) use is indicated for patients whose BMI precludes the option of bariatric surgery or who need to lose weight prior to undergoing surgery. It is a minimally invasive procedure and currently there are two main models of IGBs in use, the non-adjustable intragastric balloon (NIB), implanted for six months, and the adjustable intragastric balloon (AIB), implanted for up to 12 months.

Objective: Analyze clinical characteristics between patients receiving non-adjustable gastric balloon and the adjustable (prolonged implantation) intragastric balloon.

LATE IMPACT OF THE LAPAROSCOPIC TREATMENT OF DEEP INFILTRATING ENDOMETRIOSIS WITH SEGMENTAL COLORECTAL RESECTION.

Background: Deep infiltrating colorectal endometriosis may severely affect the quality of life and fertility of patients. Although segmental resection is a therapeutic option that provides positive outcomes in the management of symptoms, its functional effects are still unproven.

Aim: Assess the late impact of the laparoscopic approach in treating deep infiltrating endometriosis with segmental colorectal resection.

Nutritional repercussions in patients submitted to bariatric surgery.

Background: Few studies evaluated the association between nutritional disorders, quality of life and weight loss in patients undergoing bariatric surgery.

Aim: To identify nutritional changes in patients undergoing bariatric surgery and correlate them with weight loss, control of comorbidities and quality of life.

Method: A prospective cohort, analytical and descriptive study involving 59 patients undergoing bariatric surgery was done.

Laparoscopic and open colorectal resections for colorectal cancer.

Background: Surgical resection is the mainstay of treatment for colorectal cancer with curative intent.

Aim: To evaluate the postoperative results of laparoscopic and laparotomic colorectal resections for colorectal cancer.

Methods: A retrospective study of a series of 189 patients.

Effect of double-application or the application of a hydrophobic layer for improved efficacy of one-step self-etch systems in enamel and dentin.

Objectives: To evaluate the use of two alternative modes of application (double-application and placement of a hydrophobic resin coat) compared with the manufacturers' directions on the microtensile bond strength (microTBS) of one-step, self-etch systems to enamel and dentin.

Materials And Methods: Resin composite buildups were bonded to the buccal and lingual ground enamel surfaces and occlusal dentin of third molars using the following adhesives: Xeno III (XE), GBond (GB), Adper Prompt L-Pop (AD) and Clearfil SE Bond (CSE) as the control. The adhesive systems were applied: (1) following the manufacturer's directions (MD), (2) with double-application (DA) or with (3) additional placement of a hydrophobic resin layer (HR) after following the manufacturer's directions.

Can the durability of one-step self-etch adhesives be improved by double application or by an extra layer of hydrophobic resin?

Objectives: This study evaluated the immediate and 6-month resin-dentin micro-bond strength (microTBS) of one-step self-etch systems (Adper Prompt L-Pop [AD] 3M ESPE; Xeno III [XE] Dentsply De Trey; iBond [iB] Heraeus Kulzer) under different application modes.

Materials And Methods: Dentin oclusal surfaces were exposed by grinding with 600-grit SiC paper. The adhesives were applied according to the manufacturer's directions [MD], or with double application of the adhesive layer [DA] or following the manufacturer's directions plus a hydrophobic resin layer coating [HL].
