RESUMO

Up to 3.8% of human T-lymphotropic virus type-1 (HTLV-1)-infected asymptomatic carriers (AC) eventually develop HTLV-1-associated myelopathy (HAM). HAM occurs in patients with high (> 1%) HTLV proviral load (PVL). However, this cut-off includes more than 50% of ACs and therefore the risk needs to be refined. As HAM is additionally characterised by an inflammatory response to HTLV-1, markers of T cell activation (TCA), ß2-microglobulin (ß2M) and neuronal damage were accessed for the identification of ACs at high risk of HAM. Retrospective analysis of cross-sectional and longitudinal routine clinical data examining differences in TCA (CD4/CD25, CD4/HLA-DR, CD8/CD25 & CD8/HLA-DR), ß2M and neurofilament light (NfL) in plasma in ACs with high or low PVL and patients with HAM. Comparison between 74 low PVL ACs, 84 high PVL ACs and 58 patients with HAM revealed a significant, stepwise, increase in TCA and ß2M. Construction of receiver operating characteristic (ROC) curves for each of these blood tests generated a profile that correctly identifies 88% of patients with HAM along with 6% of ACs. The 10 ACs with this 'HAM-like' profile had increased levels of NfL in plasma and two developed myelopathy during follow-up, compared to none of the 148 without this viral-immune-phenotype. A viral-immuno-phenotype resembling that seen in patients with HAM identifies asymptomatic carriers who are at increased risk of developing HAM and have markers of subclinical neuronal damage.

RESUMO

BACKGROUND: Idiopathic gynecomastia is a benign breast disorder characterized by overdevelopment of male breast tissue. It can cause discomfort and concern, resulting in patients seeking diagnosis and treatment. We aimed to evaluate the efficacy of tamoxifen therapy in resolving this condition. METHODS: We undertook a prospective cohort study of all male patients who presented to our breast clinic, were diagnosed with primary gynecomastia, and were treated with a trial of tamoxifen 10 mg daily therapy, over a 10-year period from October 2004 to October 2015. All patients underwent routine investigations to exclude secondary causes of gynecomastia. The end point of interest was the complete resolution of gynecomastia. RESULTS: We included 81 patients in this study. The mean age was 42.8 years (SD 19.5 years). Of these, 28.4% were bilateral gynecomastia and 71.6% were unilateral. The majority (87.7%) of cases presented with accompanying mastalgia. Following treatment, 90.1% (n = 73) had a complete response of their gynecomastia with tamoxifen therapy. Only eight patients did not have a complete resolution following tamoxifen therapy, of which two underwent subsequent surgical resection of their symptomatic gynecomastia. CONCLUSION: Our study is the largest to date examining the role of tamoxifen in idiopathic gynecomastia, and our results show approximately nine in every 10 men treated with tamoxifen therapy had successful resolution of their symptoms. We support its use for idiopathic gynecomastia in eligible men following the careful discussion of its risks and benefits.

RESUMO

Purpose. The anterior high thoracic spine is one of the most complex segments to be accessed surgically due to anatomical constraints and transitional characteristics. We describe in detail the mini transsternal approach to metastatic, infective, traumatic, and degenerative pathologies of T1 to T4 vertebral bodies. We analyse our surgical series, indications, and outcomes. Methods. Over a 5-year period 18 consecutive patients with thoracic myelopathy due to metastatic, infective, traumatic, and degenerative pathologies with T1 to T4 vertebral bodies involvement received a mini transsternal approach with intraoperative monitoring. Frankel scoring system was used to grade the neurological status. Results. Mean follow-up was 40 months. 78% patients improved in Frankel grade after surgery and 22% patients remained unchanged. Average operation time was 210 minutes. There were no intraoperative complications. One patient developed postoperative pneumonia successfully treated with antibiotics. Conclusion. The mini transsternal is a safe approach for infective, metastatic, traumatic, and degenerative lesions affecting the anterior high thoracic spine and the only one allowing an early and direct visualisation of the anterior theca. This approach overcomes the anatomical constraints of this region and provides adequate room for optimal reconstruction and preservation of spinal alignment in the cervicothoracic transition zone with good functional patient outcomes.

RESUMO

Translational medicine bridges the gap between discoveries in biomedical science and their safe and effective clinical application. Despite the gross opportunity afforded by modern research for unparalleled advances in this field, the process of translation remains protracted. Efforts to expedite science translation have included the facilitation of interdisciplinary collaboration within both academic and clinical environments in order to generate integrated working platforms fuelling the sharing of knowledge, expertise, and tools to align biomedical research with clinical need. However, barriers to scientific translation remain, and further progress is urgently required. Collective intelligence and crowdsourcing applications offer the potential for global online networks, allowing connection and collaboration between a wide variety of fields. This would drive the alignment of biomedical science with biotechnology, clinical need, and patient experience, in order to deliver evidence-based innovation which can revolutionize medical care worldwide. Here we discuss the critical steps towards implementing collective intelligence in translational medicine using the experience of those in other fields of science and public health.
