Helicobacter pylori (H pylori) infection is the main cause of gastritis, gastroduodenal ulcer disease, and gastric cancer. After more than 20 years of experience in H pylori treatment, in my opinion, the ideal regimen to treat this infection is still to be found. Currently, apart from having to know first-line eradication regimens well, we must also be prepared to face treatment failures. Therefore, in designing a treatment strategy we should not focus on the results of primary therapy alone, but also on the final (overall) eradication rate. The choice of a "rescue" treatment depends on which treatment is used initially. If a clarithromycin- based regimen was used initially, a subsequent metronidazole-based treatment (quadruple therapy) may be used afterwards, and then a levofloxacin- based combination would be a third "rescue" option. Alternatively, it has recently been suggested that levofloxacin-based rescue therapy constitutes an encouraging second-line strategy, representing an alternative to quadruple therapy in patients with previous PPI-clarithromycin-amoxicillin failure, with the advantage of efficacy, simplicity and safety. In this case, a quadruple regimen may be reserved as a third-line rescue option. Finally, rifabutin-based rescue therapy constitutes an encouraging empirical fourth- line strategy after multiple previous eradication failures with key antibiotics such as amoxicillin, clarithromycin, metronidazole, tetracycline, and levofloxacin. Even after two consecutive failures, several studies have demonstrated that H pylori eradication can finally be achieved in almost all patients if several rescue therapies are consecutively given. Therefore, the attitude in H pylori eradication therapy failure, evenafter two or more unsuccessful attempts, should be to fight and not to surrender.

Glaucoma is the main cause of irreversible blindness globally, but the pathogenesis of glaucoma is still pending consensus. In spite of great advances during the 20th and early 21st centuries in terms of detailed knowledge of pathological processes that take place in glaucoma, the exact pathogenesis is much less clear. Hypotheses abound, and the most researched areas are ischemia at the optic nerve head, blockade of ganglion cell axonal transport, peripapillary atrophy, and changes in the characteristics of the lamina cribrosa （Nucci et al., 2008）.

Most widespread three-component penile prosthesis models are 700CXTM and Titan~. Our purpose is to assess patient and partner satisfaction after the first implant. This is a multicenter, retrospective, nonrandomized study in which all patients who met the inclusion criteria between 2009 and 2013 were included. In total, 248 patients agreed to participate. To evaluate patient satisfaction, a validated but modified 11-question questionnaire was completed （EDITS）; and a nonvalidated two-item questionnaire was given to the partner. Statistical analysis used an ordinal logistic regression model. Two hundred and forty-eight patients （194 with 700CXTM vs 54 with Titan） and 207 couples completed the questionnaire （165 with 700CXTM vs 42 with Titan）. Overall satisfaction was high. Both showed great reliability for sexual intercourse and high compliance with prior expectations. Most patients were able to manage the penile prosthesis correctly within 6 months. Postoperative penile shortening led to some dissatisfaction in 42% and 46% of cases （700CX/Titan）. Significant differences were found in three questions of patients＇ questionnaire. There were more patients satisfied with the 700CXTM （P= 0.0001）. No patient with Titan implant took longer than 6 months to optimal management. Only 4% of patients with 700CXTM implant were dissatisfied with the deflation, in contrast to 24% with the Titan （P = 0.0031）. Of the two partners＇ questions, one showed a statistically significant difference （P = 0.0026）. It seems that group 700CX＂ would recommend to re-implant the prosthesis with a greater tendency. The overall satisfaction was very high for both prostheses. The final aspect of the erected and flaccid penis was satisfactory, but both groups showed significant discontent with its final size. Partners＇ overall satisfaction was high.
