Historically, telemedicine research is predominantly published in discipline-specific telemedicine journals. However, in recent times the number of publications on telemedicine in clinical journals has increased. Acceptance of telemedicine research by clinical journals indicates a maturing of the telemedicine field. This bibliometric study reviewed telemedicine-related literature published in clinical journals from 2008 to 2018. A search was conducted in PubMed using two types of clinical outlets. (1) Top 20 journals with highest Impact Factor in the field of Medicine. (2) Top five journals with highest Impact Factor in most common Medical Specialty Areas. Analysis showed that there is a steady growth of literature relating to research and non-research publications appearing in clinical journals. Top five journals in the field of Medicine – BMJ, JAMA, Cochrane database, Medical Journal of Australia and Lancet have published 64% (n = 270) of telemedicine-related articles for the study period. Disease areas associated with telemedicine publications are consistent with global disease priorities. The review demonstrated that the most significant increase in telemedicine research published in clinical journals was focused on patient care.

Introduction: Depression is a leading cause of human disability. Telemedicine-based interventions using text messaging are currently being trialled for the management of community-based clients with clinical depression. However, little is known about the effectiveness of such methods. Methods: We searched the databases PubMed, Embase, Informit, Cochrane Central Register of Controlled Trials, PsycINFO and Scopus for randomised controlled trials (RCTs) published between January 2000 and April 2019. Studies comparing text messaging interventions to a comparator group for patients with depression were included in the review. Articles were assessed for quality using the Joanna Briggs Institute critical appraisal checklist for RCTs. Results: Nine RCTs (945 patients: 764 adults and 181 adolescents) were included in the systematic review. Five studies used text messaging as the only intervention, whilst the remaining combined text messaging with other treatment modalities such as behavioural activation or cognitive behavioural therapy. A meta-analysis was conducted on seven selected RCTs (845 patients: 664 adults and 181 adolescents). The standardised mean reduction in depression due to text messaging interventions was 0.23 (95% confidence interval: –0.02 to 0.48). There was evidence of heterogeneity in treatment effect between studies. Discussion: There is marginal evidence supporting text messaging interventions as an effective treatment modality for people living with clinical depression. However, further research is needed to determine how best to utilise text-message interventions alongside other conventional forms of health services delivery.

Introduction: Bariatric weight loss surgery is one of the most effective treatments for severe obesity. Research shows that the availability of healthcare services pre and post bariatric surgery improves behavioural change and weight loss outcomes. The aim of this systematic review is to assess the evidence relating to the use of telemedicine for providing health services to bariatric surgery patients. Methods: A search was conducted using PubMed, EMBASE, CINAHL, PsycNET and SCOPUS. Original research relating to telemedicine for bariatric surgery patients published in peer-reviewed journals were included. Results: Database search returned 258 references and a total of 10 studies were included in the review. Six studies assessed use, feasibility and acceptance of telemedicine by patients/practitioners. Studies also examined the use of telemedicine for weight loss, changes in physical activity, diet/eating or other behavioural changes. Two studies were randomised controlled trials; one showed a significant difference in outcomes between intervention and control group. Discussion: This review suggests that telemedicine may be a potential method for providing healthcare services to bariatric surgery patients. However, the current evidence base does not allow for definitive conclusions.

Intense capsaicin-induced C-fiber stimulation results in reversible lysis of the nerve soma, thereby making capsaicin wound instillation of potential interest for the treatment of post-operative pain. Clinical histological and short-term sensory studies suggest that the C-fiber function is partly re-established after skin injection of capsaicin. However, no study has evaluated the long-term effects of wound instillation of purified capsaicin on sensory functions. Patients included in a double-blind placebo-controlled randomized study of the analgesic effect of capsaicin after groin hernia repair were examined by quantitative sensory testing before, 1 week and 2 years post-operatively. The primary endpoint was occurrence of hyperalgesia/allodynia. The secondary endpoints were acute and late sensory changes between the two patient groups. Patients were blinded to the allocated treatment. Twenty (100%) capsaicin and 16 (76%) placebo-treated patients were seen at the 2 1/2 year follow-up. Hyperalgesia was seen in five capsaicin- vs. one placebo-treated patient (P=0.2). The mechanical detection threshold was significantly increased on the operated side in the capsaicin vs. placebo group at the 1-week follow-up (P0.05). The sensory function on the contralateral side was comparable between groups throughout the study (P>0.1). This small-volume study calls for further long-term safety studies of wound capsaicin instillation.
