STUDY QUESTION Are there effective and clinically validated stem cell-based therapies for reproductive diseases? SUMMARY ANSWER At the moment, clinically validated stem cell treatments for reproductive diseases and alterations are not available. WHAT IS KNOWN ALREADY Research in stem cells and regenerative medicine is growing in scope, and its translation to the clinic is heralded by the recent initiation of controlled clinical trials with pluripotent derived cells. Unfortunately, stem cell 'treatments' are currently offered to patients outside of the controlled framework of scientifically sound research and regulated clinical trials. Both physicians and patients in reproductive medicine are often unsure about stem cells therapeutic options. STUDY DESIGN, SIZE, DURATION An international working group was assembled to review critically the available scientific literature in both the human species and animal models. PARTICIPANTS/MATERIALS, SETTING, METHODS This review includes work published in English until December 2014, and available through Pubmed. MAIN RESULTS AND THE ROLE OF CHANCE A few areas of research in stem cell and reproductive medicine were identified: in vitro gamete production, endometrial regeneration, erectile dysfunction amelioration, vaginal reconstruction. The stem cells studied range from pluripotent (embryonic stem cells and induced pluripotent stem cells) to monopotent stem cells, such as spermatogonial stem cells or mesenchymal stem cells. The vast majority of studies have been carried out in animal models, with data that are preliminary at best. LIMITATIONS, REASONS FOR CAUTION This review was not conducted in a systematic fashion, and reports in publications not indexed in Pubmed were not analyzed. WIDER IMPLICATIONS OF THE FINDINGS A much broader clinical knowledge will have to be acquired before translation to the clinic of stem cell therapies in reproductive medicine; patients and physicians should be wary of unfounded claims of improvement of existing medical conditions; at the moment, effective stem cell treatment for reproductive diseases and alterations is not available. © The Author 2015.

There is a variety of disorders that affect the salivary glands in children. Among them the most prevalent are infectious diseases, whose maximum expression is mumps, which, although it has declined in recent years as a result of the administration of the MMR vaccine, it continues to appear with some frequency in primary care offices. However, we must not forget other infectious etiologies, both viral, with special mention to the human immunodeficiency virus, and bacterial. The correct diagnostic approach from primary care through clinical history and physical examination, with the help of simple additional tests such as ultrasound, also allows the appropriate focusing of other processes such as recurrent inflammation seen in recurrent parotitis of childhood and Sjögren's syndrome, or injuries that may require specialized treatment, mainly surgical, as in the case of salivary lithiasis, mucocele and ranula, and neoplastic disease.

Purpose The aim of this study was to assess the outcomes of an isolated lateral retinaculum reconstruction for iatrogenic medial patellar instability (IMPI) in patients with continued pain after failed lateral retinacular release (LRR), including associated psychometric analysis. Methods Pain was assessed using the visual analog scale (VAS) and disability was determined with the Lysholm scale. Psychological variables such as anxiety, depression, catastrophizing, and fear-of-movement beliefs were studied by using self-administered psychometric questionnaires. Results All 17 patients (13 women and 4 men) in this retrospective study had undergone LRR previously for anterior knee pain or lateral patellar instability. Four patients had undergone LRR plus proximal (Insall) realignment, and one had undergone LRR plus a medial tibial tubercle transfer. After their procedures, all had disabling symptoms. All patients underwent reconstructive surgery for IMPI. At a minimum follow-up of 2 years (range, 2 to 8 years), the mean preoperative VAS score was 7.6 (range, 5 to 9) and improved to 1.9 (range, 0 to 8) at the time of final follow-up (P <.001). The mean preoperative Lysholm score was 36.4 (range, 20 to 55), and the knee was described as bad (<65 points) in all cases. Postoperatively, it improved to 86.1 (range, 70 to 94) at final follow-up (P <.001). Before surgery, 4 patients (24%) had the clinical criteria for depression, 10 (59%) had anxiety, 7 (41%) had "catastrophizing" ideas concerning pain, and all (100%) had kinesiophobia (fear of movement). After surgery, none of the patients had depression or anxiety, none had catastrophizing ideation, and only 53% had kinesiophobia. Conclusions Reconstruction of the deep transverse layer of the lateral retinaculum (LR) using a central strip of the iliotibial band for IMPI in patients with continued pain after failed LRR can successfully treat these severely disabled patients.

This Task Force document explores the ethical issues involved in the debate about the scope of genetic screening of gamete donors. Calls for expanded donor screening arise against the background of both occasional findings of serious but rare genetic conditions in donors or donor offspring that were not detected through present screening procedures and the advent of new genomic technologies promising affordable testing of donors for a wide range of conditions. Ethical principles require that all stakeholders' interests are taken into account, including those of candidate donors. The message of the profession should be that avoiding all risks is impossible and that testing should remain proportional. © 2014 The Author. Source
