Background: The diagnosis of follicular carcinoma is often difficult to make on pathological analysis, as the histological distinction from follicular adenoma rests solely on the presence of capsular or vascular invasion. Even on retrospective review of the histopathology after the disease biology has declared itself as malignant, the pathological diagnosis of malignancy may not be possible to make., Methods: We report three cases in which patients were initially diagnosed with benign follicular lesions, but re-presented with locally recurrent disease and a subsequent malignant disease course., Results: We describe a rare entity of follicular thyroid carcinoma that demonstrates a locally recurrent and eventually metastatic disease phenotype, despite persistently benign pathological findings., Conclusion: We highlight that if local recurrence occurs in discrete anatomical tissue planes, or in the thyroid bed following open total thyroidectomy for 'benign multinodular goitre', the possibility of this rare presentation of follicular thyroid carcinoma should be considered., (© 2023 The Authors.

The clinical outcomes of kidney donors with a prior history of nephrolithiasis are poorly defined. We conducted a systematic review assessing the post-donation clinical outcomes of kidney donors with a history of nephrolithiasis. Electronic databases (Ovid and Embase) were searched between 1960 and 2021 using key terms and Medical Subject Headings (MeSH) - nephrolithiasis, renal stones, renal transplantation and renal graft. Articles included conference proceedings and journal articles and were not excluded based on patient numbers. Primary outcome was donor stone-related event. Secondary outcomes were renal function upon follow-up or post-operative nephrectomy complications. In summary, 340 articles were identified through database search. We identified 14 studies (16 cohorts) comprising 432 live donors followed up for a median of 26 months post live kidney donation. Six donors donated the stone-free kidney whilst 23 live donors had bilateral stones. Mean stone size was 4.2 ± 1.4 mm (1-16) with average follow up duration of 21.1 months (1-149). Twelve studies provided primary outcome (n = 138 patients) and eight (n = 348) for secondary outcomes. One donor had a stone-related event upon follow up. A total of 195 patients had eGFR <60 upon follow up. However, they were not significantly different when compared to renal function of live donors that didn't have pre-donation nephrolithiasis. Many of the studies couldn't provide long term follow up, coupled with limited data regarding the nature of the pre-donation stone disease. In conclusion, this systematic review shows that we have very limited information upon which to base recommendation regarding pre-donation risk of post-donation complications. Longer term follow up is required and lifelong follow up with live donor registries will aid further understanding., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Aim: The ever-expanding organ supply and demand gap necessitates alternate sources of organ donors. Initially thought to be a contraindication, organ procurement from nonsurvivable burns patients is possibly an additional organ donor source. We aimed to conduct a systematic review investigating the prevalence and outcomes of the use of burn victims as a source of organ donation for transplantation., Methods: Medline and EMBASE were searched between 1990 and 2020, using the following keywords: organ procurement, organ donation, organ transplantation, and burns. Studies were not excluded based on patient numbers and included both published abstracts/conference proceeding and journal articles. Studies were excluded if specific organs were not identified or if posttransplant outcomes were not recorded. Primary and secondary outcomes of interest were post-transplantation organ function and complications respectively., Results: Six manuscripts met study inclusion criteria. Fourteen burns donors were identified, including both donation after circulatory death and donation after brain death pathways. The total body surface area of burn ranged from 4% to 90%. A total of 4 hearts, 2 lungs, 8 livers, 1 pancreas, and 24 kidneys were transplanted with varying duration of follow-up and outcomes., Conclusion: A very small number of studies have reported the posttransplant outcomes of organs derived from victims of burn injury, including very limited information regarding graft function in the short or long term. Hence, recommendations for the utilization of organs from victims of burn injury should remain guarded and subject to surveillance., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Objective: Did not wait (DNW) is a frequently cited ED key performance indicator. We conducted a network-based observational study of consecutive DNW presentations., Methods: Prospective cohort study of Western Sydney Local Health District with a primary outcome measure of reported 30-day all-cause mortality and secondary outcomes of demographic characteristics and representation risk. For re-presenting patients who were subsequently admitted, a manual review of electronic records and incident report systems based on a priori plan assessed each case for the length of stay and adverse outcomes., Results: During the study window, there were 1114 DNW presentations with 172 (15.4%) re-presentation within 72 h. The analysis of re-presented patients did not reveal adverse outcomes or prolonged length of stay. A review of available outcomes data revealed one DNW patient died within 30 days but had a previous palliative plan for terminal illness., Conclusion: While a proportion of DNW patients re-presented within 72 h, an excess prevalence of poor outcomes were not observed., (© 2021 Australasian College for Emergency Medicine.)
