Vaccinations are one of the main public health tools for the control of vaccine-preventable diseases. If a child is identified as having had an allergic reaction to a vaccine, subsequent immunisations will probably be suspended - with the risks such a decision implies. The incidence of severe allergic reactions is very low, ranging between 0.5 and 1 cases/100,000 doses. Rather than the vaccine antigens as such, the causes of allergic reactions to vaccines are often residual protein components of the manufacturing process such as gelatine or egg, and less commonly yeasts or latex. Most vaccine reactions are mild and circumscribed to the injection site; although in some cases severe anaphylactic reactions can be observed. If an immediate-type allergic reaction is suspected at vaccination, or if a child with allergy to some of the vaccine components is scheduled for vaccination, a correct diagnosis of the possible allergic process must be made. The usual vaccine components must be known in order to determine whether vaccination can be safely performed.

BACKGROUND: The task force on Acute Circulatory Failure of the Scandinavian Society of Anaesthesiology and Intensive Care Medicine produced this guideline with recommendations concerning the use of crystalloid vs. colloid solutions in adult critically ill patients with acute circulatory failure.
METHODS: Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology was used to grade the quality of evidence and to determine the strengths of the recommendations. As efficacy and harm may vary in different subpopulations of patients with acute circulatory failure, we produced recommendations for general intensive care unit (ICU) patients and those with sepsis, trauma and burn injury.
RESULTS: For general ICU patients and those with sepsis, we recommend using crystalloids for resuscitation rather than hydroxyethyl starch and we suggest using crystalloids rather than gelatin and albumin. For patients with trauma we recommend to use crystalloids for resuscitation rather than colloid solutions. For patients with burn injury we provide no recommendations as there are very limited data from randomised trials on fluid resuscitation in this patient population.
CONCLUSIONS: We recommend using crystalloid solutions rather than colloid solutions for resuscitation in the majority of critically ill patients with acute circulatory failure.

We report herein a case of a patient with high-flow priapism for whom a gelatin sponge was used as a temporary occlusive agent in arterial embolization, resulting in favorable outcome. The American Urological Association guideline on the management of priapism recommends using temporary occlusive agents. We reviewed all reports published after the introduction of this guideline to compare temporary and permanent occlusive agents in terms of symptom improvement and onset of erectile dysfunction. The rate of symptom improvement differed significantly between temporary and permanent embolizing materials, but no significant difference was apparent in the rate of erectile function improvement.
