Intra-abdominal infections can be classified into uncomplicated or complicated(peritonitis). Peritonitis is divided into primary, secondary, and tertiary. Tertiaryperitonitis is the less common but the most severe among peritonitisstratifications, being defined as a recurrent intra-abdominal infection that occurs48 h after a well-succeeded control of a secondary peritonitis. This disease has acomplex pathogenesis that is closely related to the capacity of the peritonealcavity to activate immunological processes. Patients who progress to persistentperitonitis are at an increased risk of developing several infectious complicationssuch as sepsis and multiple organ failure syndrome. Moreover, tertiary peritonitisremains an important cause of hospital death mainly among patients withassociated risk factors. The microbiological profile of organisms causing tertiaryperitonitis is often different from that observed in other types of peritonitis. Inaddition, there is a high prevalence of multidrug-resistant pathogens causing thiscondition, and an appropriate and successful clinical management depends on anearly diagnosis, which can be made easier with the use of clinical scorespresenting a good prediction value during the intensive care unit ***, immediate therapy should be performed to control theinfectious focus and to prevent new recurrences. In this sense, the treatment isbased on initial antimicrobial therapy and well-performed peritoneal drainage.

Objective: This study aims to describe the experience with diode laser cyclophotocoagulation in the control of intraocular pressure and resolution of pain in patients with refractory glaucoma. Methods: Retrospective study. 64 eyes of 60 patients who underwent cyclophotocoagulation between January 2008 and March 2014. Evaluation of the pre- and post-operative intraocular pressure, the control of ocular pain, the number of anti-glaucoma drugs used in pre- and post-intervention, the rate of complications and the success rate. Results: There was an overall success rate of 81.3%, with 9 eyes needing a second intervention. There was a mean reduction of 52.6% of the preoperative mean intraocular pressure of 41.25 to 19.56 mmHg at 12 months observation (p < 0.001). There was also a statistically significant reduction in the number of anti-glaucoma drugs used from 3.19 to 2.01 per eye and the resolution of pain in 75% of patients. Conclusions: cyclophotocoagulation is an effective procedure, with an expected positive impact on quality of life of patients as a result from the decreased number of anti-glaucoma drugs, sustained intraocular pressure reduction and resolution of pain.

Prosthechea is a neotropical genus, belonging to the family Orchidaceae. The Brazil recorded 32 species of the genus of which nine occur in the state of Bahia, including P. silvana and P. moojenii. The first, P. silvana is epiphytic, endemic Atlantic Forest areas of South and Southeast of the Bahia and morphologically similar to P. moojenii, rupicolous species considered endemic to the Chapada Diamantina. There are doubts whether these two species are really distinct, because they differ only as to the way of life and aspects related to the size of the inflorescence and floral structure. Thus the anatomical study of these two species, emerges as a tool that aims to investigate the delimitation of these taxa. For this study, the sheet was cut freehand with a razor blade to obtain cross sections and treated by chemical means to obtain paradermic sections, all the material was stained with safranine/Astra blue (safrablau) and safranin, respectively, and the sections were then mounted between a semipermanent and cover slipped slides. The results allowed to distinguish P. silvana of the P. moojenii through the following characteristics observed in the leaf (thickening of the cell walls of epidermal cells, amount and disposition of sclerenchyma fibers and fiber arrangement of vascular and vascular bundles in the mesophyll) and root (number of arcs of xylem and phloem, thickening of cells median cortex), infers taxonomic characters for the genus. The data indicated anatomical distinction between the two species studied here of the Prosthechea, however, suggest the anatomical analysis of other organs to reproductive and vegetative.

AIM:To evaluate the influence of MUC1 mucin variable number of tandem repeats (VNTR) variability on H pylori adhesion to gastric cells. METHODS: Enzyme linked immunosorbent assay (ELISA)-based adhesion assays were performed to measure the adhesion of different H pylori strains (HP26695 and HPTx30a) to gastric carcinoma cell lines (GP202 and MKN45) and GP202 clones expressing recombinant MUC1 with different VNTR lengths. RESULTS: Evaluation of adhesion results shows that H pylori pathogenic strain HP26695 has a significantly higher (P < 0.05) adhesion to all the cell lines and clones tested, when compared to the non-pathogenic strain HPTx30a. Bacteria showed a significantly higher (P < 0.05) adhesion to the GP202 cell line, when compared to the MKN45 cell line. Furthermore, both strains showed a significantly higher (P < 0.05) adhesion to GP202 clones with larger MUC1 VNTR domains. CONCLUSION: This work shows that MUC1 mucin variability conditions H pylori binding to gastric cells. The extent of bacterial adhesion depends on the size of theMUC1 VNTR domain. The adhesion is further dependent on bacterial pathogenicity and the gastric cell line. MUC1 mucin variability may contribute to determine H pylori colonization of the gastric mucosa.
