Maxillofacial trauma poses an obvious threat to the patient's airway, which may not be immediately evident. In the multiply injured patient, the co-existence of actual or potential injuries elsewhere may complicate airway management, notably in the presence of full spinal immobilization. Following high-velocity trauma, injuries to the cervical spine must be assumed to be present. They also need to be ruled out in an appropriate and timely manner, as patients may wish to sit up. Assessment and management of the airway in maxillofacial trauma can be difficult, requiring a senior anaesthetist or other individual appropriately trained in emergency airway care. A number of management options may exist to protect the airway, each with advantages and drawbacks. Agitation and vomiting can occur unexpectedly and need to be managed safely with due consideration to the spine. Oral and maxillofacial surgeons need to be aware of these dilemmas and their early warning signs, and be skilled in emergency surgical airway procedures, especially if involved as part of the trauma team. Prolonged immobilization is associated with significant morbidity and mortality. A number of protocols currently exist for 'clearing' the spine. Imaging now plays a greater role, especially in the obtunded, unconscious or intubated patient, and this is discussed.

Norovirus is increasingly recognized as a leading cause of outbreaks of foodborne disease. We report on an outbreak in Austria that reached a total of 176 cases, affecting pupils and teachers from four schools on a skiing holiday in a youth hostel in the province of Salzburg in December 2007. A questionnaire was sent to the four schools in order to obtain data from persons attending the school trip on disease status, clinical onset, duration of illness and hospitalization. A cohort study was undertaken to identify the sources of infection. The school trip attendees were interviewed by questionnaire or face-to-face on their exposure to food items from the menu provided by the hostel owner. Of the 284 school holiday-makers, 176 fitted the definition of an outbreak case (attack rate 61.9%). A total of 264 persons on the ski holiday participated in the cohort study (response rate 93%). The day-by-day food-specific analyses did not find any food items served on any of five days (December 8-12) of the holiday to be associated with infection risk. The day-specific risk analyses revealed Monday December 10 (RR: 9.04; 95% CI: 6.02-13.6; P < 0.001) and Tuesday December 11 (RR: 3.37; 95% CI: 2.56-4.43; P < 0.001) as the two most risky days for having being exposed to norovirus. According to the epidemiological investigation, airborne transmission of norovirus originating from the first vomiting case most probably initiated this outbreak; foodborne genesis was excluded. During recent years, norovirus has become increasingly established as the most important causative agent of epidemic gastroenteritis in holiday-makers all over Europe. Tourism is one of the primary industries in Austria. Timely involvement of the relevant public health authorities is essential in any outbreak of norovirus gastroenteritis, irrespective of its genesis.

Following a school ski-trip to Austria from 10 to 18/02/2017, nine of 25 participants of the group from Lower Saxony (Germany) developed gastroenteritis. The students and teachers (17-41 years) shared meals in a hotel. Active case finding revealed further cases among German school groups from North Rhine-Westphalia and Schleswig-Holstein, staying at the same hotel in February 2017. We conducted two retrospective cohort studies using self-administered questionnaires on clinical symptoms and food consumption. We defined a case as a trip participant in February 2017, staying at the aforementioned hotel and developing diarrhoea, vomiting or abdominal pain during or within ten days after the trip and/or who had a stool sample tested positive for STEC within four weeks after the trip. During the outbreak investigation, Austrian authorities detected that unlabeled raw cow milk delivered by a dairy farm had been offered at the hotel for breakfast during January and February 2017. Stool samples of participants, samples of milk served in the hotel and fecal samples of various animals kept at the milk-delivering farm were examined by culture and polymerase chain reaction. STEC isolates were typed using Pulsed-field Gel Electrophoresis (PFGE) and Whole-Genome Sequencing (WGS). All 25 participants from Lower Saxony completed the questionnaire on symptoms and milk consumption; 14 were cases (56%). Thirteen of 20 participants who had consumed cold milk fell ill (risk ratio (RR): 3.25; 95%-confidence interval (CI): 0.55-19.32). Of 159 trip participants from North Rhine-Westphalia, 81 completed the questionnaire (51%), 25 were cases (31%); RR for cold milk was 2.11 (CI: 0.89-5.03). The combined RR for cold milk in both groups was 2.49 (CI: 1.16-5.35). Shiga toxin 1a-gene and eaeA-gene positive STEC O103:H2 were detected in nine of 32 patients' stool samples and in two of 18 dairy farm cattle. Nine isolates from human stool samples and two isolates from cattle fecal samples yielded the same strain with an almost identical PFGE-pattern and WGS-profile. Microbiological and epidemiological evidence identified raw cow milk as the vehicle. Results may have been compromised by misclassification of cases due to a recall bias and mild symptoms. As a result of this outbreak investigation, the Austrian authorities enforced Austrian law in the hotel, to provide milk only when pasteurized. We recommend re-emphasizing the risk of raw milk consumption to providers.

Intracranial hemorrhage (ICH) is rarely seen in patients with thalassemia. A seven-year-old male, known case of beta-thalassemia major, on irregular packed cell transfusions (elsewhere) and non-compliant with chelation therapy, presented with congestive cardiac failure (Hb-3 gm/dl). He received three packed red cell transfusions over 7 days (cumulative volume 40 cc/kg). On the 9th day, he developed projectile vomiting and two episodes of generalized tonic-clonic convulsions with altered sensorium. He had exaggerated deep tendon reflexes and extensor plantars. CT-scan of brain revealed bilateral acute frontal hematoma with diffuse subarachnoid hemorrhage (frontal and parietal). Coagulation profile was normal. CT-angiography of brain showed diffuse focal areas of reduced caliber of anterior cerebral, middle cerebral, and basilar and internal carotid arteries (likely to be a spasmodic reaction to subarachnoid hemorrhage). He required mechanical ventilation for 4 days and conservative management for the hemorrhage. However, on the 18th day, he developed one episode of generalized tonic-clonic convulsion and his sensorium deteriorated further (without any new ICH) and required repeat mechanical ventilation for 12 days. On the 28th day, he was noticed to have quadriplegia (while on a ventilator). Nerve conduction study (42nd day) revealed severe motor axonal neuropathy (suggesting critical illness polyneuropathy). He improved with physiotherapy and could sit upright and speak sentences at discharge (59th day). The child recovered completely after 3 months. It is wise not to transfuse more than 20 cc/kg of packed red cell volume during each admission and not more than once in a week (exception being congestive cardiac failure) for thalassemia patients.
