Facial paralysis due to a spitting cobra bite.

The global burden of snakebites is growing, particularly its nonfatal sequelae. Therefore, the World Health Organization reinstated snakebites to its list of Neglected Tropical Diseases. We describe the case of a 4.

Predicting morbidity in older travellers during a short-term stay in the tropics: the ELDEST study.

Background: Older persons may suffer more from travel-related health problems because of ageing and underlying chronic disorders. Knowledge on who is more likely to have these health problems helps to tailor travel health advice more specifically. This study aimed to determine predictors of travel-related morbidity in older travellers by assessing their pre-travel characteristics and performance using physical and cognitive functioning tests.

Hypereosinophilia: a diagnostic challenge.

Hypereosinophilia encompasses a broad differential diagnosis of atopy/allergic reactions, drug reactions, parasitic infections and paraneoplastic syndromes. Although mostly of limited clinical significance, hypereosinophilia can also be related to hematological malignancies. One has to be aware of the potential for secondary organ damage for example, in the case of hypereosinophilic syndrome.

Neutrophil gelatinase-associated lipocalin (NGAL) predicts the occurrence of malaria-induced acute kidney injury.

Background: Acute kidney injury (AKI) is a frequently encountered complication of imported Plasmodium falciparum infection. Markers of structural kidney damage have been found to detect AKI earlier than serum creatinine-based prediction models but have not yet been evaluated in imported malaria. This pilot study aims to explore the predictive performance of neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) for AKI in travellers with imported P.

A case report of transfusion-transmitted Plasmodium malariae from an asymptomatic non-immune traveller.

Background: The incidence of transfusion-transmitted malaria is very low in non-endemic countries due to strict donor selection. The optimal strategy to mitigate the risk of transfusion-transmitted malaria in non-endemic countries without unnecessary exclusion of blood donations is, however, still debated and asymptomatic carriers of Plasmodium species may still be qualified to donate blood for transfusion purposes.

Case Description: In April 2011, a 59-year-old Dutch woman with spiking fevers for four days was diagnosed with a Plasmodium malariae infection.

Copeptin does not accurately predict disease severity in imported malaria.

Background: Copeptin has recently been identified to be a stable surrogate marker for the unstable hormone arginine vasopressin (AVP). Copeptin has been shown to correlate with disease severity in leptospirosis and bacterial sepsis. Hyponatraemia is common in severe imported malaria and dysregulation of AVP release has been hypothesized as an underlying pathophysiological mechanism.

Imported Mayaro virus infection in the Netherlands.

A Dutch couple, presenting with persisting arthralgias, temporary fever and rash after a stay in Surinam were diagnosed with Mayaro virus infection. Mayaro virus is a relatively unknown South American Alphavirus responsible for dengue-like clinical features and persisting arthralgias. An important, but probably underappreciated cross-reactivity with other Alphaviruses like Chikungunya virus is present, which may become of clinical importance in the event the various Alphaviruses will have overlapping geographical distributions and in seroprevalence studies.

Hyponatraemia in imported malaria is common and associated with disease severity.

Background: Hyponatraemia (serum sodium < 135 mmol/L) has long been recognized as a complication of malaria. However, few studies have been done in non-immune adult populations. It has not been investigated previously how hyponatraemia is distributed among the various Plasmodium species, and its association with malaria severity is unknown.

Efficacy and safety of exchange transfusion as an adjunct therapy for severe Plasmodium falciparum malaria in nonimmune travelers: a 10-year single-center experience with a standardized treatment protocol.

Background: Even in circumstances where optimal antimalarial and supportive treatment is available, severe Plasmodium falciparum malaria is still associated with a significant case fatality. Although exchange transfusion (ET) has been considered as a controversial adjunct therapy, we have not encountered any case fatality since ET was introduced as a standard adjunct therapy for patients with severe malaria.

Study Design And Methods: In this retrospective cohort study of 25 patients with severe malaria, the efficacy and safety of ET as an adjunct to parenteral antimalarial treatment (which was implemented in our hospital starting in 1998) were evaluated and compared with 31 historical control patients who were treated with conventional parenteral antimalarial treatment in the period before ET was added to the standard of care for severe malaria (generally before 1997).

Early small bowel perforation and cochleovestibular impairment as rare complications of typhoid fever.

Two Indian migrant workers suffering from fever and malaise were admitted to the hospital directly after arrival in the Netherlands. The first patient was 25-year-old man who had fever and rigors on admission. The patient was treated for presumptive typhoid fever with ciprofloxacin.

Procalcitonin as a biomarker for severe Plasmodium falciparum disease: a critical appraisal of a semi-quantitative point-of-care test in a cohort of travellers with imported malaria.

Background: Imported malaria occurs as a relatively rare event in developed countries. As a consequence, most clinicians have little experience in making clinical assessments of disease severity and decisions regarding the need for parenteral therapy or high-level monitoring. In this study, the diagnostic accuracy of procalcitonin (PCT) for severe Plasmodium falciparum disease was assessed in a cohort of 100 consecutive travellers with various species of imported malaria.

Narrow vision after view-broadening travel.

Loss of vision is a threatening presentation of disease. We describe a case of acute idiopathic blind spot enlargement in a 26-year-old male traveler who presented with narrow vision after a journey to Indonesia. Although the patient used mefloquine at time of presentation, we were unable to retrieve sound data incriminating mefloquine in this rare eye disorder.

A probable case of Irukandji syndrome in Thailand.

The Irukandji syndrome is a jellyfish envenomation caused by Carukia barnesi or related jellyfish. In literature, the distribution of "Irukandji-like" syndromes is restricted to Australia. We report a case of probable Irukandji syndrome in Thailand.
