Left ventricular longitudinal strain and strain rate measurements in paediatric patients in long-term treatment for Chagas disease.

Introduction: Previous echocardiographic studies failed to show residual alterations of heart function in paediatric patients that have received treatment for Chagas disease. While the echocardiogram is the fundamental front-line tool for evaluating heart function, the appearance of new techniques allows a more detailed analysis. We aimed to evaluate systolic and diastolic function with new techniques in a paediatric population with Chagas disease several years after treatment completion.

[Immunizations in adults with cardiovascular disease. Summary of the Consensus of the Argentine Cardiology Society].

Cardiovascular diseases are the leading cause of death in most regions of the world, usually followed by infectious diseases. For decades, infections in general, and particularly those involving the respiratory system, have been known to be associated with an increased risk of cardiovascular and cerebrovascular events, and their consequent morbidity and mortality. Although vaccines are an excellent strategy in the prevention of infectious diseases, the proportion of immunized adults in our country is frankly deficient.

Four glycoproteins are expressed in the cat zona pellucida.

The mammalian oocyte is surrounded by a matrix called the zona pellucida (ZP). This envelope participates in processes such as acrosome reaction induction, sperm binding and may be involved in speciation. In cat (Felis catus), this matrix is composed of at least three glycoproteins called ZP2, ZP3, and ZP4.

Rabbit zona pellucida composition: a molecular, proteomic and phylogenetic approach.

The zona pellucida (ZP) participates in sperm-egg interactions during the first steps of fertilization. Recent studies have shown that the ZP matrix of oocytes in several species is composed of four glycoproteins, designated as ZP1, ZP2, ZP3 and ZP4, rather than the three described in mouse, pig and cow. In this study, investigations were carried out to unveil a fourth glycoprotein in the rabbit (Oryctolagus cuniculus) ZP.

Partial humeral head resurfacing and Latarjet coracoid transfer for treatment of recurrent anterior glenohumeral instability.

Bone deficiencies of either the humeral head or glenoid fossa may cause recurrent shoulder instability following soft tissue stabilization procedures. The engaging Hill-Sachs lesion, a major risk factor for instability, has been identified in a majority of patients with recurrent anterior instability. Guidance for surgical management of large humeral head deficiency presents few available options, with even fewer clinical data to support any one technique.

Arthroscopic versus open acromioplasty: a meta-analysis.

Background: To address persisting controversy in the literature concerning the efficacy of arthroscopic compared to open acromioplasty, a meta-analysis was performed to evaluate the treatment effect after both approaches.

Hypothesis: The final clinical outcomes will be the same after both open and arthroscopic acromioplasty. However, the arthroscopic technique results in faster recovery and less postoperative morbidity as reflected by faster return to work and decreased hospital stays.

Suture anchor and percutaneous intra-articular transtendon biceps tenodesis.

Several arthroscopic biceps tenodesis techniques have been described for surgical management of tendonitis and/or partial thickness tears of the long head of the biceps brachii tendon resulting in recalcitrant anterior shoulder pain. This chapter describes an arthroscopic tenodesis using percutaneous intra-articular transtendon technique with suture anchor fixation. The percutaneous technique allows excellent access to the biceps tendon, and the addition of a suture anchor provides superior fixation to isolated soft tissue fixation.

Arthroscopic anterior shoulder instability repair: techniques, pearls, pitfalls, and complications.

Initial attempts to replicate the success of open anterior shoulder instability procedures using arthroscopic procedures were associated with unacceptably high failure rates. The resultant focus on identifying clear surgical indications and improving both arthroscopic technique and instrumentation has culminated in arthroscopic success rates approaching those of established open procedures. Current experience shows that with careful patient selection, strict adherence to proper surgical technique, and the avoidance of common surgical errors, excellent clinical results can be achieved with arthroscopic instability repair.

Pharmacokinetics of dexketoprofen trometamol in healthy volunteers after single and repeated oral doses.

The pharmacokinetics of dexketoprofen trometamol were evaluated in two studies using healthy volunteers. In the first study, the relative bioavailability of a single oral capsule of dexketoprofen free acid 25 mg or dexketoprofen trometamol 25 mg (given as 37 mg of the trometamol salt) was compared to ketoprofen 50 mg in 18 healthy volunteers. In the second study, the pharmacokinetics and tolerability of oral dexketoprofen trometamol in tablet form were evaluated after either a single 25 mg dose (24 volunteers) or a repeated dose of 25 mg twice daily for 7 days (12 volunteers).

Pharmacokinetics of Dexketoprofen Trometamol in Healthy Volunteers After Single and Repeated Oral Doses.

The pharmacokinetics of dexketoprofen trometamol were evaluated in two studies using healthy volunteers. In the first study, the relative bioavailability of a single oral capsule of dexketoprofen free acid 25 mg or dexketoprofen trometamol 25 mg (given as 37 mg of the trometamol salt) was compared to ketoprofen 50 mg in 18 healthy volunteers. In the second study, the pharmacokinetics and tolerability of oral dexketoprofen trometamol in tablet form were evaluated after either a single 25 mg dose (24 volunteers) or a repeated dose of 25 mg twice daily for 7 days (12 volunteers).

No sex-related pharmacokinetic and pharmacodynamic differences of captopril.

Captopril is an angiotensin-converting enzyme inhibitor (ACEI) used in the treatment of hypertension and congestive heart failure and has demonstrated its cardiovascular effects in experimental animal models, healthy volunteers and patients. The aim of this study was to find out whether or not differences in the pharmacokinetic profile and the haemodynamic response of a 100-mg single oral dose of captopril appeared between subjects of both sexes. Twenty-four young healthy volunteers (12 males and 12 females) took part in the trial.
