Background: Primary spontaneous pneumothorax occurs in patients with no underlying lung disease and guidelines recommend chest tube drainage for the first episode, with surgical intervention reserved for recurrent episodes, persistent air leak or failure of lung re-expansion. Modern surgical management is associated with reduced length of hospital stay and superior freedom from recurrence compared with chest tube drainage alone. The objective of this study was to identify risk factors for failed chest tube drainage in patients who present with first episode primary spontaneous pneumothorax.

Methods: A retrospective analysis of patients who presented to Royal Prince Alfred Hospital, Australia with first episode PSP and underwent chest tube insertion was performed. Patient demographics and size of pneumothorax were examined in relation to the primary outcome, a composite of failed chest tube drainage and recurrent ipsilateral pneumothorax.

Results: Fifty-five patients underwent chest tube drainage for first episode primary spontaneous pneumothorax between 1st January 2017 and 31st December 2020. Complete lung collapse on admission chest x-ray was associated with an increased risk of the primary outcome (63% versus 19%, OR 7.3 [96% CI 2.0-27.4), P = 0.004).

Conclusion: This small retrospective study found that patients that undergo chest drain insertion for first episode primary spontaneous pneumothorax who present with complete lung collapse on admission are at high risk of requiring pleurodesis and therefore may benefit from early surgical referral.

Background: Simulation-based education (SBE) has been increasingly used to train healthcare workers in low-resource settings and has been endorsed by the World Health Organization (WHO). Consideration of the educational and cultural context is important to maximize the effectiveness of SBE. Despite its demonstrable benefits, there have been no studies of the general approach in the Pacific Islands. This study aimed to determine the factors that influence the uptake and success of SBE in the Pacific Islands.

Methods: In this qualitative study, participants were recruited via professional networks to contribute to focus groups. Questions focused on participants' previous experiences and perspectives on SBE. Data were manually transcribed before thematic analysis. The reporting of the research was guided by the Standards for Reporting Qualitative Research (SRQR). Human Research Ethics Committee approval was obtained.

Results: Two focus groups were conducted with 16 participants from six Pacific Island countries. Six themes and 15 subthemes were conceptualized from the data. Uptake of SBE is challenged by resource availability, clinical workloads and geographic remoteness. However, locally-driven solutions and positive attitudes towards SBE facilitate its success.

Conclusion: This study reveals the complexity of factors affecting the uptake and success of SBE in the Pacific Islands. These findings can serve to optimize the impact of existing and future SBE programmes and may be considered by educators prior to programme implementation.

Background: The aim of this study was to determine the effects of nursing education and counselling provided by telephone to individuals undergoing coronary artery bypass graft surgery on their discharge satisfaction levels and self-care power levels.

Method: The study was conducted using a randomized controlled experimental research model with a pre-test-post-test control group (30 individuals in the experiment group and 30 individuals in the control group). Routine nursing care was applied to the patients in the control group throughout their attendance, and no training or intervention was made after discharge. By contrast, in addition to routine nursing care, the for 4 weeks in the experimental group received nursing education and counselling services by phone in the post-discharge period. A 'Personal Information Form,' 'Discharge Training Satisfaction Scale,' and 'Self-Care Strength Scale,' which were prepared by the researchers and included the personal information of the patients, were used to collect the data.

Results: The difference between the pre-test self-care power scale and discharge education satisfaction scale sub-dimensions of the groups and the mean score of the total score was not statistically significant. The post-test self-care power scale and discharge education satisfaction scale sub-dimensions and total score averages of the patients in the experimental group were higher than in the control group, and the difference between them was statistically significant (P <0.05).

Conclusion: The nursing education and counselling services given to the patients on the phone increased their self-care skill levels and discharge satisfaction levels.

Background: Isolated splenic abscesses are rare, but increasingly reported with newer organisms and changes in mechanisms involved. We conducted a comparative review of publications from 1900-1977, 1977-1986, 1987-1995, and 1996-2022.

Methods: A systematic search in Embase and PubMed resulted in 522 publications (1111 cases). Data was tabulated, analysed, and compared.

Results: Patient demographics and symptoms remain unchanged although more Asian patients were reported. Metastatic infections remain the main cause, but COVID-19-linked and iatrogenic causes post bariatric surgery and splenic artery embolization are increasingly reported. Aerobic organisms remain the commonest (68%), with a variety of exotic organisms reported. Splenectomy remains the definitive treatment, although antibiotics only and percutaneous aspiration/catheter-drainage are increasingly used with reasonable outcomes, with salvage splenectomy for therapeutic failures not having significantly higher mortality than upfront splenectomy.

Conclusions: Isolated splenic abscesses continue to be uncommon, with diagnosis requiring a high degree of suspicion. Non-surgical options for treatment can sometimes be definitive.

Introduction: Clinical recognition of potential immune-mediated allergic responses to implanted metal devices is increasing. For orthopaedic implants, while 'pure' compounds are used in specific circumstances, the majority of components are alloys - a combination of two or more distinct metals. Titanium is found commonly in many orthopaedic devices and is often championed as a 'hypoallergenic' option or inclusion. In the absence of a relevant previously published summary on the topic, this paper explores the current state-of-understanding of titanium allergy and proposes a patient management algorithm whereby such immune reactions are clinically-suggested.

Methods: A structured, systematic literature review was performed following PRISMA search principles to provide a contemporary summary-of-understanding in this area and to highlight clinical and knowledge deficiencies.

Results: Thirty-five topic-related articles were identified, the majority reflecting small case series' or proof-of-concept studies. The general standard of scientific evidence available was poor. Justification for arthroplasty utilization of titanium as a 'hypoallergenic' option is largely extrapolated from non-orthopaedic domains.

Conclusions: Both ionic and conjugated titanium particles released from implant surfaces have the potential to trigger innate immune responses and true allergy. There exists no simple, high-sensitivity, screening test for titanium allergy. Conventional skin-patch testing is unreliable due to poor dermal penetration. Given established lymphocyte and macrophage activation pathways for allergy responses, in vitro methods using both cell-types show diagnostic promise. Surgical biopsy analysis from host-implant interfaces remains the contemporary 'gold-standard', however this represents an invasive, costly and highly-specialized approach not readily available in most settings. Further research to establish reliable/accessible diagnostic methods are indicated.

Since its first description in 1898, pancreaticoduodenectomy has constantly been improved, allowing increasingly more complex operations to be performed even with a minimally invasive approach: laparoscopic and, in recent years, robotic approach. In most cases, similarly to open surgery, parenchymal transection is performed after the creation of a retropancreatic tunnel to ensure adequate control of the mesenteric vessels before sectioning the parenchyma. Sometimes tunnelling can be very difficult even dangerous to achieve, due to conditions such as: vascular involvement by the neoplasm of superior mesenteric vein (SMV) or portal vein (PV); fibrosis secondary to acute pancreatitis (AP) or radiotherapy. In such conditions, it seems suitable to avoid tunnelling before parenchymal transection. We will describe how we perform the standard technique which we will call ‘Tunnel First approach’ (TF) and then our new ‘Parenchyma Transection-First’ (PTF) approach in its two variants: ‘bottom to top’ and ‘top to bottom’.

Unnecessary care, where the potential for harm exceeds the potential for benefit, is widespread in medical care. Orthopaedic surgery is no exception. This has significant implications for patient safety and health care expenditure. This narrative review explores unnecessary care in orthopaedic surgery. There is wide geographic variation in orthopaedic surgical practice that cannot be explained by differences in local patient populations. Furthermore, many orthopaedic interventions lack adequate low-bias evidence to support their use. Quantifying the size of the problem is difficult, but the economic burden and morbidity associated with unnecessary care is likely to be significant. An evidence gap, evidence-practice gap, cognitive biases, and health system factors all contribute to unnecessary care in orthopaedic surgery. Unnecessary care is harming patients and incurring high costs. Solutions include increasing awareness of the problem, aligning financial incentives to high value care and away from low value care, and demanding low bias evidence where none exists.

Introduction: The 'gap' continues to exist between the Indigenous and non-Indigenous populations within Australia, with Indigenous Australians continuing to experience poorer health outcomes, and a reduced life expectancy of 10.6 years for males and 9.5 for females. Indigenous Australians are far more likely to suffer from ischaemic heart disease. We sought to investigate the outcomes of Indigenous Australians undergoing isolated coronary artery bypass graft surgery (CABG) at a single institution.

Methods: A retrospective cohort study comparing Indigenous with non-Indigenous Australians from prospectively collected data were performed for all patients who underwent isolated CABG at a single centre between 2015 and 2018. The primary endpoint was 30-day mortality with secondary endpoints including deep sternal wound infection, new renal failure, length of stay, stroke and rate of readmission.

Results: A total of 905 patients were included in the study. The Indigenous cohort had 130 patients and the non-Indigenous cohort contained 775 patients. The baseline preoperative characteristics were significantly different between the two cohorts, with Indigenous patients younger (55.7 vs. 64.6 years), more likely to be female (33.1% vs. 16.4%) and to be dialysis-dependent (10% vs. 1.2%). The primary outcome was more likely in Indigenous Australians, with a 30-day mortality rate of 3.1% compared with 0.8%. There was a higher incidence of new renal failure (12.3% vs. 5.9%), red blood cell transfusion (30% vs. 20.8%).

Conclusion: Indigenous patients undergoing CABG at our institution have significantly more co-morbidities as well as worse post-operative outcomes and strategies to address this are urgently required.
