While they are both vaccine preventable, hepatitis A and B both remain prevalent diseases across the globe. Catherine Brewer explores the significance of informing travellers of the infection risks and provides useful knowledge for practice nurses providing travel advice The term hepatitis means inflammation of the liver and the most prevalent types are A and B. These are also the serotypes more relevant to travel medicine. Hepatitis A is contracted via the faecal–oral route, often in contaminated food and water. It is predominantly found in countries with poor sanitation, but outbreaks can occur in the UK. Travellers need to be assessed to see if their destination and the nature of their travels will put them at risk. If this is the case, health advice and the vaccine should be offered. Hepatitis B is contracted via blood and body fluids and has a vast global health impact. Many individuals who contract this disease in early life will go onto be chronic carriers and have long-term complications. The UK is a low-risk country and most travellers going to high-risk areas will remain low risk. However, health professionals need to assess individual travellers and their itineraries to identify those at an increased risk. Advice must be given and the vaccine should be administered if appropriate, and both of these conditions can impact travellers as well as the wider public. Professionals must understand the diseases, risks, management strategies, guidelines and vaccine schedules to provide the optimum care to their patients.

Q fever is a zoonotic disease caused by the bacterium Coxiella burnetii and is associated with significant morbidity and mortality in both adults and children. Australia is the only country that has produced and registered a Q fever vaccine for human use, but this vaccine is licenced only for people aged over 15 years as data and experience in children are limited. This review describes the experience of Q fever vaccination of known paediatric cases in Australia to date. Patients aged younger than 15 years who received the Q fever vaccination had data abstracted from medical records after consent was obtained from the relevant guardians. Data on risk factors for Q fever, skin testing procedure, dose of vaccination, adverse effects and follow-up assessment were obtained. Twelve children were identified as having received the Q fever vaccination. Vaccination was feasible, with empirical weight-based dose adjustment performed for younger children. There were no significant adverse effects. Q fever vaccine may be safe in children and should be considered in children who are at significant risk of Q fever infection. Safe vaccine protocols with proven efficacy will allow children of all ages to be protected. Prospective studies of vaccination in children are indicated. Expanding available Q fever registries to include children would allow outcomes to be systematically followed.

Increasing numbers of U.K. travellers are visiting rabies-endemic countries. This article describes how this invariably fatal disease is transmitted to humans and how it may be prevented by increased awareness, and pre and post-exposure vaccination. It aims to help practitioners identify patients at increased risk of rabies, and looks at the common myths and misconceptions travellers may have about rabies and rabies vaccination.

In hoofdstuk 1 van dit boek is besproken dat de adviezen met betrekking tot vaccinatie en malariaprofylaxe voor reizigers regelmatig veranderen. De hygiene wordt in verschillende delen van de wereld steeds beter, waardoor bijvoorbeeld risico’s op buiktyfus op bestemmingen zoals Thailand en Maleisie de laatste decennia veel kleiner zijn geworden.

The article deals with the fundamental principles of mortgage lending, which together form the legal basis for this type of lending. The paper highlights and discusses the following principles of mortgage: repayment, payment, security, maturity, specialty, bound (the principle of making), glasnost (publicity), reliability, priority (seniority), irrevocably and differentiation. Separately investigate the principle of purpose.

The Cell-Dyn 4000 automated hematology analyzer (CD4000) has the ability to detect malaria patients, but it remained unclear whether it could detect persistent malaria post-treatment. To investigate this, we used the CD4000 to evaluate 68 Korean patients with Plasmodium vivax malaria, and control groups of 50 patients with fever and 50 asymptomatic patients. The results from the instrument-generated scatter plot (derived by laser light depolarization) were compared with microscopy results. During the initial diagnosis, the sensitivity of the CD4000 in detecting malaria was 91.2%. On day 3 of follow-up, the CD4000 results matched those from microscopy by 96.7%. Malaria was not detected by either method beyond 14 days post-presentation. Interestingly, the atypical depolarizing events, which typify the presence of malaria in the analyzer, were highly correlated with the levels of parasitaemia in serially diluted samples of the leucocyte-depleted blood, and the CD4000 detected parasites down to the level of 288 +/- 17.7/microl. Our findings suggest that the phenomenon of atypical light depolarization could be influenced by parasitaemia levels, and be used as a screening method for P. vivax malaria patients, as well as for the therapeutic monitoring.
