Traumatic hand amputations among children in Greece: epidemiology and prevention potential.

BACKGROUND: Traumatic hand and finger amputations frequently lead to permanent disability. OBJECTIVE: To investigate their epidemiological characteristics and estimate the prevention potential among children 0-14 years old, through a cross-sectional survey. METHODS: Nationwide extrapolations were produced based on data recorded between 1996 and 2004 in the Greek Emergency Department Injury Surveillance System and existing sample weights. Incident and injury related characteristics were analysed to identify preventable causes. RESULTS: Among 197,417 paediatric injuries, 28,225(14%) involved the hand and fingers resulting in 236 amputations (∼1% of hand injuries). The annual probability to seek emergency department care for a hand injury was 3%. The estimated incidence rate (IR) of hand amputations was 19.7/100,000 person-years. Over 50% concerned children 0-4 years old (male:female=2:1), peaking at 12-24 months. Male preschoolers suffered the highest IR (38.7/100,000). Migrant children were overrepresented among amputees. Of all amputations, 64% occurred in the house/garden and 14% in day-care/school/sports activities, usually between 08:00 and 16:00 (61%). Doors were the product most commonly involved (55% overall; 72% in day-care/school/gym) followed by furniture/appliances (15%) and machinery/tools (7%). Crushing was the commonest mechanism. Inadequate supervision and preventive measures were also frequently reported. 5% of the amputees were referred to specialised units for replantation/reconstructive surgery. CONCLUSIONS: The majority of paediatric hand and finger amputations could be prevented in Greece, particularly among preschoolers, by a single product modification, namely door closure systems, coupled with improved supervision. Paediatricians should incorporate this advice into their routine child-safety counselling. This country-specific profile supports the need for maintaining similar databases as an indispensable tool for assisting decision-making and preventing disabling and costly injuries.

Conservative management versus endovascular or open surgery in the spectrum of type B aortic dissection.

BACKGROUND: Type B aortic dissection is a life-threatening acute aortic condition often with acute ischemic signs or symptoms. With initial management focusing on alleviating malperfusion and pain, and avoiding propagation of dissection or rupture both systolic blood and pulse pressure should be reduced initially by an aggressive medical approach. In the setting of persistent signs of complications endovascular strategies have replaced open surgery and led to a fourfold increase in early survival and better long-term outcomes. METHODS: An electronic health database search was performed on articles published between January 2006 and July 2017. Publications were included in this review if (I) the index aortic pathology was type B aortic (distal) dissection; (II) when medical management, open surgical replacement or thoracic endovascular aortic repair were among those options; (III) when at least one of all basic outcome criteria such as survival, spinal cord ischemia and cerebrovascular accident was reported; (IV) when ≥15 serial patients were included. A total of 62 studies were eligible and analysed. RESULTS: Our manuscript has summarized data collected over 12 years on management specific outcomes in the setting of distal aortic dissection and provides an up-to-date interpretation of the published evidence. For complicated cases, treated acutely, the 30-day or in-hospital mortality was 7.3% when managed by endovascular means, whereas the pooled rate for 30-day or in-hospital mortality was 19.0% when subjected to open repair. For acute uncomplicated type B dissection usually treated with blood pressure lowering medications, the pooled 30-day or in-hospital mortality rate was 2.4%. Survival rates at 5 years averaged at 60% (40% mortality). Freedom from any aortic event ranged from 34.0% to 83.9%, underlining an inherent risk of progression and late complications. For chronic complicated type B dissection, the rates of stroke, paraplegia and operative mortality following endovascular repair ranged from 5% to 13%, 2% to 13% and 2 to 13%, respectively, while 5-year survival rates after open repair ranged from 60% to 90%. In chronic uncomplicated type B dissection almost 90% of patients survive initial hospitalization and were subjected to medical management with a 5-year survival of 50-80%. However, up to 20-55% of medically treated patients develop aneurysmal degeneration after 5 years with an unknown risk of rupture. CONCLUSIONS: Currently, the less invasive strategy of endovascular repair (as compared to open surgery) provides improved 30-day or in-hospital survival in the setting of complicated acute type B aortic dissection and may seek broad application. Open surgical aortic reconstruction should be left to experienced aortic centres if endovascular management is not an option.

Starting out in minimally invasive aortic valve replacement in the UK.

OBJECTIVES: Here we aim to describe in detail the logical procedure and philosophical approach to establish a minimally access aortic valve replacement programme in the current era. METHODS: A real example of a National Health Service Trust in the United Kingdom has been described in a step-wise manner. RESULTS: The outcomes of the new procedure established in this fashion are reported and the philosophical lessons learnt from the experiences are highlighted. CONCLUSIONS: It is hoped that this paper will act as a template for newly established surgeons to embark onto a mini-AVR programme. An open-minded and enthusiastic team will undoubtedly be able to facilitate the introduction of this 'new service'. A sensible approach will provide safe and sustainable outcomes.
