Efficacy of embolotherapy for the treatment of pelvic congestion syndrome: A systematic review.

Pelvic congestion syndrome (PCS) poses a significant health, diagnostic, and economic challenges. Transcatheter embolisation has emerged as a promising treatment for PCS. A systematic review was performed in order to assess the safety and efficacy of transcatheter embolisation in the treatment of PCS. A systematic search of electronic databases was performed using 'PubMed', 'Embase', 'Medline (OVID)', and 'Web of Science', for articles pertaining to efficacy of embolotherapy for the treatment of pelvic congestion syndrome. A total of 25 studies were included in this systematic review with a combined total of 2038 patients. All patients included were female with a mean average age of 37.65 (31-51). Of the 25 studies, 18/25 studies reported pre- and post-procedural pelvic pain outcomes using a visual analogue scale (VAS). All studies showed a reduction in VAS post-procedure. Transcatheter embolisation had a high technical success rate (94%) and an overall complication rate of 9.0%, of which 10.4% were major and 89.6% were minor. Fifteen out of 19 (78.9%) major complications required a subsequent intervention. Transcatheter embolisation using various techniques is effective and safe in treating PCS. A low quality of evidence limits the currently available literature; however, embolisation has shown to improve symptoms in the majority of patients with low complication rates and recurrence rates.

Adjuvant chemotherapy improves survival amongst octogenarians following resection of colorectal adenocarcinoma.

BACKGROUND: The Australian population is ageing, with an increasing number of patients diagnosed with colorectal cancer in their eighth decade. This group represents a challenging cohort to deliver multidisciplinary care, with increased morbidity and mortality related to surgical and oncological therapies. This project aimed to compare surgical and oncological outcomes in octogenarian and non-octogenarian patients with colorectal cancer. METHODS: A matched case-control retrospective review of a prospectively maintained institutional database of colorectal cancer patients treated between 2005 and 2021 was conducted. Patient demographics, treatment details, peri-operative complications, and long-term survival were reported. The primary outcome, cancer-specific survival, was investigated using time-to-event analysis and interrogated with multivariate regression. RESULTS: There were 747 patients included in the study. There was no difference in five-year cancer-specific survival and recurrence-free survival between cohorts. Multivariate analysis for octogenarians confirmed a significant hazard signal associated with worsening cancer stage and a survival benefit associated with the administration of adjuvant therapy. However, we noted that stage-matched octogenarian patients received less adjuvant treatment compared to non-octogenarians. CONCLUSION: Octogenarians undergoing treatment for colorectal cancer have similar cancer-specific survival and recurrence-free survival to non-octogenarians. Our study demonstrates a survival benefit when adjuvant therapy is provided to octogenarians, despite only half of this cohort receiving therapy compared to their younger peers. Further research into adjuvant therapy with surgical resection for CRC in older Australians is required.

Transoral endoscopic thyroidectomy vestibular approach (TOETVA): initial experience in Australia.

BACKGROUND: Thyroidectomy is traditionally an open procedure. The potential for and unpredictability of patients developing an unsightly anterior neck scar has led many investigators to develop various 'scarless' thyroidectomy techniques. Here we report on our initial experience, and to our knowledge, the first and largest series of this technique in Australia and New Zealand. METHODS: Across two centres in Western Australia, three Endocrine surgeons utilized the Transoral Endoscopic Thyroidectomy vestibular approach (TOETVA). Key endpoints such as operating time, blood loss, pain scores, recurrent laryngeal nerve injury and hypoparathyroidism was collected. Data was analysed using R statistical program. RESULTS: One hundred and two TOETVAs were performed between March 2018 and May 2021. There were 66 hemithyroidectomies, 34 total thyroidectomies (four converted to open), and two isthmusectomies. We noted a trend in median operating time decreasing over the study period. There were no cases of permanent recurrent laryngeal nerve palsy, wound infection, seroma or haematoma. We had four instances of open conversion; one temporary RLN palsy, and 12 cases of temporary hypoparathyroidism. CONCLUSION: This is the first series of TOETVA reported in Australia and New Zealand. Our results demonstrate that with appropriate surgeon experience, training, collaboration, and in well selected patients, this is a feasible and safe thyroidectomy technique. We hope that our work will build confidence in Endocrine Surgical units seeking to develop this technique in Australia.

Lung abscess: 14 years of experience in a tertiary paediatric hospital.

BACKGROUND: Lung abscess is a rare condition in paediatrics with a paucity of literature. Intravenous antibiotics is the main therapy; however interventional radiological approaches have led to the use of percutaneous drainage. Surgery is reserved for the management of complications. The aim of this study was to describe lung abscess in a cohort of paediatric patients' and determine associations between factors at presentation and outcomes. METHODS: A 14-year retrospective cohort study was conducted including all children who presented to a tertiary paediatric hospital in Western Australia with lung abscess. Clinical characteristics, laboratory and radiologic findings, management options and clinical outcomes were examined. RESULTS: Sixty-eight patients (median age 3.6 (0.08-17.6) years; 44.1% female) were identified to have a lung abscess, with 81% being primary lung abscess. Staphylococcus aureus (including MRSA) and Streptococcus pneumoniae were the most common organisms identified, with S. aureus being most common in Aboriginal patients (80%). A total of 25 antibiotics were prescribed on initiation of treatment in over 20 combinations. 44.9% of patients had complications and hospitalization was prolonged. Patients with S. aureus had longer hospitalization (20.5 days (3-67) than those without (median 13 days (3-52), p = 0.04). There were no associations between factors at presentation and subsequent outcomes. Factors at presentation were not associated with outcomes. CONCLUSION: There is unwarranted variation in management of paediatric lung abscess and high complication rates. There is a need for collaboration and clinical practice guidelines to standardize care for lung abscess in children.

Retrospective cohort study of neonatal early onset of sepsis and the role of the EOS calculator in a level II nursery.

BACKGROUND: Sepsis is a major cause of mortality and morbidity in neonates. With the improvement in health care standards, the incidence of neonatal Early Onset Sepsis (EOS) has reduced significantly. A recent Web-based EOS-calculator has been introduced with the aim to reduce the use of IV antibiotics in neonates. The role of the EOS-calculator has yet to be ascertained in this regional Special Care Nursery (SCN) in Western Australia. This study aims at examining the local incidence of culture proven EOS and the role of the EOS calculator. METHOD: It is a retrospective study examining all newborns ≥35 weeks gestation throughout 2019 (Jan-Dec 2019) who received IV-antibiotics. The local incidence of culture-proven EOS was established and applied onto the EOS calculator. The recommended management by the EOS-calculator was cross-examined with the local EOS guideline. Overall proportion of reduction in IV antibiotics use was formulated. Other relevant laboratory data extracted was analysed with Pearson's correlation test with the EOS scores. RESULTS: Total included sample was n = 252 with an annual birth of 1880s indicating 13.4% of all neonates born throughout year 2019 was treated with IV antibiotics. The local incidence of culture-proven EOS was 0.5/1000. By applying the EOS-calculator, a significant reduction of IV antibiotics usage from 13.4% to 3.9% (z value 10.4, p < 0.0001) could be achieved in this cohort. Sixty three percent of neonates who received IV antibiotics in this cohort were classified as 'clinically well' based on the EOS-calculator. CONCLUSION: The EOS-calculator could reduce the use of IV antibiotics in the neonatal population significantly in this regional SCN (from 13.4% to 3.9%). Judicial use of IV antibiotics is imperative as part of the holistic care for the neonates. Implementation of the EOS-calculator must be done strategically considering the local incidence of EOS and other health care policies.

Serelaxin Treatment Reduces Oxidative Stress and Increases Aldehyde Dehydrogenase-2 to Attenuate Nitrate Tolerance.

Background: Glyceryl trinitrate (GTN) is a commonly prescribed treatment for acute heart failure patients. However, prolonged GTN treatment induces tolerance, largely due to increased oxidative stress and reduced aldehyde dehydrogenase-2 (ALDH-2) expression. Serelaxin has several vasoprotective properties, which include reducing oxidative stress and augmenting endothelial function. We therefore tested the hypothesis in rodents that serelaxin treatment could attenuate low-dose GTN-induced tolerance. Methods and Results: Co-incubation of mouse aortic rings ex vivo with GTN (10 µM) and serelaxin (10 nM) for 1 h, restored GTN responses, suggesting that serelaxin prevented the development of GTN tolerance. Male Wistar rats were subcutaneously infused with ethanol (control), low-dose GTN+placebo or low-dose GTN+serelaxin via osmotic minipumps for 3 days. Aortic vascular function and superoxide levels were assessed using wire myography and lucigenin-enhanced chemiluminescence assay respectively. Changes in aortic ALDH-2 expression were measured by qPCR and Western blot respectively. GTN+placebo infusion significantly increased superoxide levels, decreased ALDH-2 and attenuated GTN-mediated vascular relaxation. Serelaxin co-treatment with GTN significantly enhanced GTN-mediated vascular relaxation, reduced superoxide levels and increased ALDH-2 expression compared to GTN+placebo-treated rats. Conclusion: Our data demonstrate that a combination of serelaxin treatment with low dose GTN attenuates the development of GTN-induced tolerance by reducing superoxide production and increasing ALDH-2 expression in the rat aorta. We suggest that serelaxin may improve nitrate efficacy in a clinical setting.
