Improved surgical technique for laparoscopic Roux-en-Y gastric bypass reduces complications at the gastrojejunostomy.

Roux-en-Y gastric bypass (RYGBP) is one of the most commonly performed bariatric procedures for morbidly obese patients. It is associated with effective long-term weight loss, but can lead to significant complications, especially at the gastrojejunostomy (GJS). All the patients undergoing laparoscopic RYGBP at one of our two institutions were included in this study. The prospectively collected data were reviewed retrospectively for the purpose of this study, in which we compared two different techniques for the construction of the GJS and their effects on the incidence of complications. In group A, anastomosis was performed on the posterior aspect of the gastric pouch. In group B, it was performed across the staple line used to form the gastric pouch. A 21-mm circular stapler was used in all patients. A total of 1,128 patients were included between June 1999 and September 2009-639 in group A and 488 in group B. Sixty patients developed a total of 65 complications at the GJS, with 14 (1.2%) leaks, 42 (3.7%) strictures, and 9 (0.8%) marginal ulcers. Leaks (0.2% versus 2%, p = 0.005) and strictures (0.8% versus 5.9%, p < 0.0001) were significantly fewer in group B than in group A. Improved surgical technique, as we propose, with the GJS across the staple line used to form the gastric pouch, significantly reduces the rate of anastomotic complications at the GJS. A circular 21-mm stapler can be used with a low complication rate, and especially a low stricture rate. Additional methods to limit complications at the GJS are probably not routinely warranted.

An alternative technique to reveal polysaccharides in Toxoplasma gondii tissue cysts

Ultrathin sections of tissue cysts isolated from the brain of Toxoplasma gondii infected mice were submitted to two different methodologies derived from the periodic acid - Schiff's reagent (PAS) technique. The use of osmium tetroxide vapor as a developing agent of the aldehyde oxidation to reveal polysaccharides with periodic acid resulted in positive reaction in amylopectin granules in bradyzoites, as well as in the wall and matrix of the cysts, with excellent increment of the ultrastructural morphology. This technique can be used for study of T. gondii-host cell intracellular cycle, the differentiation tachyzoite-bradyzoite, and also for the formation of cysts into the host cells.

Hand cleaning technique

This reversible poster is part of an extension of the cleanyourhands campaign, aimed at preventing the spread of healthcare associated infections (HCAIs) in community healthcare settings including primary care and dental services, residential and nursing homes (including independent sector homes), hospices and independent clinics/hospitals. It is designed for pump dispenser or handwashing areas to heighten awareness of protecting patients from avoidable infections by cleaning of hands using proper techniques.

The use of the polymerase chain reaction and restriction fragment length polymorphism technique associated with the classical morphology for characterization of Lymnaea columella, L. viatrix, and L. diaphana (Mollusca: Lymnaeidae)

The specific identification of Lymnaeid snails is based on a comparison of morphological characters of the shell, radula, renal and reproductive organs. However, the identification is complicated by dissection process, intra and interspecific similarity and variability of morphological characters. In the present study, polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) techniques targeted to the first and second internal transcribed spacers (ITS1 and ITS2) rDNA and to the mitochondrial 16S ribosomal gene (16S rDNAmt) were used to differentiate the species Lymnaea columella, L. viatrix, and L. diaphana from some localities of Brazil, Argentina, and Uruguay as well as to verify whether the molecular results corroborates the classical morphological method.PCR-RFLP analysis of the ITS1, ITS2, and 16S using 12 restriction enzymes revealed characteristic patterns for L. columella and L. diaphana which were concordant with the classical morphology. On the other hand, for L. viatrix populations a number of 1 to 6 profiles were generated while morphology provided the species pattern results.
