The number of fatal accidents and severe injuries, resulting from road accidents, may be reduced through applying an integrated approach to safety on roads. The strategies and programmes for improving road traffic should include the following measures: reducing the risk of exposure to an accident, prevention of accidents, reduction in bodily injuries sustained in accidents, and reduction of the effects of injuries by improvement of post-accident medical care.

Amphizoic amoebae generate a serious human health threat due to their pathogenic potential as facultative parasites, causative agents of vision-threatening Acanthamoeba keratitis (AK). Recently, AK incidences have been reported with increasing frequency worldwide, particularly in contact lens wearers. In our study, severe cases of AK in Poland and respective pathogenic isolates were assessed at clinical, morphological, and molecular levels. Misdiagnoses and the unsuccessful treatment in other ophthalmic units delayed suitable therapy, and resistance to applied chemicals resulted in severe courses and treatment difficulties. Molecular assessment indicated that all sequenced pathogenic corneal isolates deriving from Polish patients with AK examined by us showed 98–100% homology with Acanthamoeba genotype T4, the most prevalent genotype in this human ocular infection worldwide. In vitro assays revealed that the pathogenic strains are able to grow at elevated temperature and have a wide adaptive capability. This study is our subsequent in vitro investigation on pathogenic Acanthamoeba strains of AK originating from Polish patients. Further investigations designed to foster a better understanding of the factors leading to an increase of AK observed in the past years in Poland may help to prevent or at least better cope with future cases.

Medical facilities, while providing both essential and demanding health care to society’s most vulnerable populations, also belong to the most demanding category of risk to human life if and when a crisis event occurs within its walls. The development of a safe evacuation plan for these facilities is extremely complicated, as the evacuation of medical facilities is much more complex than for other critical infrastructure. In this category, the evacuated patients constitute a specific risk group requiring specialized medical care. Hospitalized persons may be dependent on life-saving measures, are unconscious or immobile, are significantly restricted in movement or mentally unbalanced, being dependent on the continued assistance of trained third parties. Additionally, the medical transport of evacuated patients becomes more difficult due to the limited capacity of ambulances and available health care facilities to transport them to, which are increasingly limited due to their overcrowded census. The study aimed to analyze the requirements which are placed on hospitals in Poland to ensure the safety of patients in case of an evacuation. The research method used in the paper was retrospective analysis and evaluation of the media and literature. We have found, that Polish law imposes an obligation on the administrator of a medical facility to ensure the safety of both patients and employees. The regulations cover issues of technical conditions to be met by buildings and their location, prevention, and fire protection requirements, and the determination of which staff is responsible for the evacuation. However, available documents fail to describe what the hospital evacuation process itself should entail under emergency evacuation. Taking into account the complexity of the hospital evacuation process, health care facilities should have a well-developed plan of action that must be implemented at least once a year in the form of facility-wide training. Evacuation drills should not be avoided. Only trained procedures offer the possibility of later analysis to identify and eliminate errors and provide the opportunity to acquire skill sets and habits which promote the behaviors expected in real-life emergencies.

BackgroundAsymptomatic pancreatic necrosis should be managed conservatively, regardless of its extent. However, late sequelae and safety of non-interventional management in patients with asymptomatic walled-off necrosis remain unclear.AimsThe purpose of this study was to report the clinical outcome of outpatient expectant management in a cohort of patients with walled-off necrosis who were discharged asymptomatic after an episode of acute pancreatitis.MethodsSixteen patients with walled-off necrosis asymptomatic at discharge were identified retrospectively from a single institution. Data were analyzed for the type of complications, their incidence and treatment.ResultsSeven of 16 patients (44 %) did not experience any complications during a median follow-up of 17 months. Nine of 16 patients (56 %) became symptomatic or developed complications within a median follow-up of 49 days after discharge. The most common complication was infection of pancreatic necrosis which occurred in 7 of 9 patients. Six of these patients were successfully treated with minimally invasive techniques. In 5 of 7 patients, infection of necrosis was due to oral commensal bacteria. Acute intracavitary hemorrhage and intractable abdominal pain developed in one patient each. There was no mortality in this series.ConclusionsOutpatient watchful waiting can be used safely in patients with asymptomatic walled-off necrosis, although nearly half of them eventually develop complications which require interventional treatment. Most late infections of pancreatic necrosis are probably due to a blood-borne transmission of oral commensal bacteria.
