Abstract: Pyoderma gangrenosum (PG) is an atypical ulceration of the skin with unknown aetiology, usually associated with autoimmune systemic illnesses and haematological malignancies. Diagnosis is based on clinical suspicion and exclusion of other conditions. Treatment options vary greatly, ranging from conservative local and systemic immunosuppression to surgical measures, including utation, but none is shown to be universally effective. Currently no guideline regarding escalation of treatment exists. Based on a review of the current literature and three illustrative cases of PG, a working treatment guideline is presented for wound practitioners.

Abstract: Impalpable breast lesions generally require image‐guided localisation for breast‐conserving surgery. A standard technique is to place a hook wire (HW) within the lesion. Radioguided occult lesion localisation using iodine seeds (ROLLIS) involves inserting a 4.5 mm iodine‐125 seed (seed) into the lesion. We hypothesised that a seed could be more precisely positioned in relation to the lesion than a HW and that this may be associated with a lower re‐excision rate. Retrospective review of consecutive participant data from three ROLLIS RCT (ACTRN12613000655741) sites. Participants underwent preoperative lesion localisation (PLL) with seed or HW between September 2013 and December 2017. Lesion and procedural characteristics were recorded. Distances between (1) any part of the seed or thickened segment of the HW (‘TSHW’) and the lesion/clip (‘distance to device’ DTD) and (2) centre of the TSHW/seed and centre of the lesion/clip (device centre to target centre ‘DCTC’) were measured on immediate postinsertion mammograms. Pathological margin involvement and re‐excision rates were compared. A total of 390 lesions (190 ROLLIS and 200 HWL) were analysed. Lesion characteristics and guidance modality used were similar between groups. Ultrasound‐guided DTD and DCTC for seed were smaller than for HW (77.1% and 60.6%, respectively, P ‐value 0.001). Stereotactic‐guided DCTC for seeds was 41.6% smaller than for HW ( P ‐value = 0.001). No statistically significant difference in the re‐excision rates was found. Iodine‐125 seeds can be more precisely positioned for preoperative lesion localisation than HW, however, no statistically significant difference in re‐excision rates was detected.

Abstract: The ocean moderates the world’s climate through absorption of heat and carbon, but how much carbon the ocean will continue to absorb remains unknown. The North Atlantic Ocean west (Baffin Bay/Labrador Sea) and east (Fram Strait/Greenland Sea) of Greenland features the most intense absorption of anthropogenic carbon globally the biological carbon pump (BCP) contributes substantially. As Arctic sea-ice melts, the BCP changes, impacting global climate and other critical ocean attributes (e.g. bio ersity). Full understanding requires year-round observations across a range of ice conditions. Here we present such observations: autonomously collected Eulerian continuous 24-month time-series in Fram Strait. We show that, compared to ice-unaffected conditions, sea-ice derived meltwater stratification slows the BCP by 4 months, a shift from an export to a retention system, with measurable impacts on benthic communities. This has implications for ecosystem dynamics in the future warmer Arctic where the seasonal ice zone is expected to expand.

Abstract: Persistent air‐leaks can be difficult to localize in radiology. Bronchoscopic management of air‐leaks requires identification of the leak's location to allow suitable targeted treatment. One‐way endobronchial valves have become a suitable option for persistent air‐leaks. In this report, a combination scintigraphy and one‐way endobronchial valve treatment successfully resolved a persistent air‐leak.
