Diving-related otological injuries: Initial assessment and management.

BACKGROUND: Scuba diving-related otological injuries comprise the majority of diving-related incidents that present to general practitioners (GPs). Correct diagnosis and management are key to prevent permanent hearing loss and vertigo. OBJECTIVE: The aim of this article is to increase awareness of the pathophysiology of otological diving injuries and provide an approach to initial assessment and treatment, as well as to highlight particular circumstances in which onward referral is required. DISCUSSION: Accurate diagnosis and treatment of diving-related otological injuries by GPs can have profound positive effects on a patient's long-term outcomes. Complete otolaryngological assessment in those who have previously had a dive-related injury is critical to ensure patient safety prior to recommencing scuba diving.

Diagnosing phyllodes tumours of the breast: how successful are our current preoperative assessment modalities?

BACKGROUND: To assess the efficacy of the diagnostic modalities used in the preoperative assessment of phyllodes tumours. METHODS: In this retrospective study of patients treated at Princess Alexandra Hospital, 51 phyllodes tumours in 49 patients diagnosed between 2005 and 2016 were reviewed with regard to their preoperative findings to assess which modalities, including clinical findings, mammography, ultrasound, fine needle aspiration and core biopsy, were most diagnostically discriminating. Data on demographics and management were also collected. RESULTS: While 90.2% of lesions were clinically palpable and an abnormality was seen in 86.1% of lesions subjected to mammography, the findings in relation to these two modalities were essentially those of non-discriminatory masses. Furthermore, although 100% of the phyllodes lesions were sonographically visible, suspicion of a phyllodes tumour was only noted in 21.6% of cases. Fine needle aspiration yielded results suspicious for phyllodes in 21.1% of cases while core biopsy resulted in confirmed or suspected phyllodes tumour diagnoses in 69.2% of instances. Serial measurements of phyllodes tumours yielded an average growth rate of 8.04 mm per 365 days. CONCLUSION: In the preoperative diagnosis of phyllodes tumours of the breast, ultrasound was a more discriminating imaging modality compared to mammography, and core biopsy demonstrated a superior accuracy of diagnosis over fine needle biopsy. A significant increase in lesion size over a short timeframe should also alert to the possibility of a phyllodes tumour.

Behavior change theory, content and delivery of interventions to enhance adherence in chronic respiratory disease: A systematic review.

BACKGROUND: We sought to describe the theory used to design treatment adherence interventions, the content delivered, and the mode of delivery of these interventions in chronic respiratory disease. METHODS: We included randomized controlled trials of adherence interventions (compared to another intervention or control) in adults with chronic respiratory disease (8 databases searched; inception until March 2015). Two reviewers screened and extracted data: post-intervention adherence (measured objectively); behavior change theory, content (grouped into psychological, education and self-management/supportive, telemonitoring, shared decision-making); and delivery. "Effective" studies were those with p < 0.05 for adherence rate between groups. We conducted a narrative synthesis and assessed risk of bias. RESULTS: 12,488 articles screened; 46 included studies (n = 42,91% in OSA or asthma) testing 58 interventions (n = 27, 47% were effective). Nineteen (33%) interventions (15 studies) used 12 different behavior change theories. Use of theory (n = 11,41%) was more common amongst effective interventions. Interventions were mainly educational, self-management or supportive interventions (n = 27,47%). They were commonly delivered by a doctor (n = 20,23%), in face-to-face (n = 48,70%), one-to-one (n = 45,78%) outpatient settings (n = 46,79%) across 2-5 sessions (n = 26,45%) for 1-3 months (n = 26,45%). Doctors delivered a lower proportion (n = 7,18% vs n = 13,28%) and pharmacists (n = 6,15% vs n = 1,2%) a higher proportion of effective than ineffective interventions. Risk of bias was high in >1 domain (n = 43, 93%) in most studies. CONCLUSIONS: Behavior change theory was more commonly used to design effective interventions. Few adherence interventions have been developed using theory, representing a gap between intervention design recommendations and research practice.
