The last decades have seen a marked increase in the number of immunocompromised patients. These patients are at higher risk for severe outcomes from infections, many of which are vaccine-preventable diseases. However, such complex cases raise several important issues of concern: 1. ⋯ Do clinicians have sufficient or updated information concerning the safety, efficacy and contraindications to vaccination of such at-risk patients? 6. Which vaccines can be safely administered to immunocompromised travelers to tropical destinations? The answers to those questions are multifaceted, and data on safety, immunogenicity, and efficacy of vaccines for immunocompromised populations are limited. This article summarizes the current recommendations for immunizations in immunocompromised patients, indications and potential adverse effects.

Primary headaches are one of the most common disorders of childhood, with migraine and tension type headaches (TTHs) being the most frequent ones. In spite of their prevalence, there is paucity of knowledge regarding the underlying pathophysiological mechanisms that cause headaches and regarding the unique aspects of headaches in children and adolescents. ⋯ Most of our current knowledge regarding primary headaches in children and adolescents is driven from extrapolations from studies that were conducted with adult patients. Therefore, it needs to be validated for the different age groups. Migraines may be diagnosed effectively based on the 2nd edition of the International Classification of Headache Disorders (ICHD-II), however, TTH is diagnosed mainly by the absence of features found in other headache types. Treatment strategies for primary headaches vary according to patient's age, family structure, culture and beliefs, headache diagnosis, and based on the disability the headache imposes on the patient's daily living. It was shown that a multidisciplinary approach, that includes continuing counseling, education, and reassurance, in combination with pharmacological and non-pharmacological treatment, is an effective strategy for children and adolescents suffering from primary headaches. Further studies are needed to enrich our knowledge about the pathophysiological mechanisms that cause headaches in children and adolescents and to develop efficient strategies to alleviate their burden.
