Human Plasmodium knowlesi Infection Detected by Rapid Diagnostic Tests for Malaria

We describe a PCR-confirmed case of Plasmodium knowlesi infection with a high parasitemia level and clinical signs of severe malaria in a migrant worker from Malaysian Borneo in the Netherlands. Investigations showed that commercially available rapid antigen tests for detection of human Plasmodium infections can detect P. knowlesi infections in humans

Different perceptions of the burden of upper GI endoscopy: an empirical study in three patient groups

Background: Few studies have evaluated patients' perceived burden of cancer surveillance tests. Cancer screening and surveillance, however, require a large number of patients to undergo potentially burdensome tests with only some experiencing health gains from it. We investigated the determinants of patients' reported burden of upper gastrointestinal (GI) endoscopy by comparing data from three patient groups. Patients and methods: A total of 476 patients were included: 180 patients under regular surveillance for Barrett esophagus (BE), a premalignant disorder; 214 patients with non-specific upper GI symptoms (NS), and 82 patients recently diagnosed with upper GI cancer (CA). We assessed pain, discomfort and overall burden experienced during endoscopy, symptoms in the week afterwards and psychological distress over time (Hospital Anxiety and Depression scale and Impact of Event Scale). Results: Two-thirds (66%) of patients reported discomfort and overall burden of upper GI endoscopy. Only 23% reported any pain. BE patients reported significantly less discomfort, pain and overall burden than the other patients: those with NS reported more discomfort, CA patients more pain, and both more overall burden. These differences could be statistically explained by the number of previous endoscopies and whether sedation was provided or not, but not by patient characteristics. Conclusion: The perception of upper GI endoscopy varies by patient group, due to potential adaptation after multiple endoscopies and aspects of th

Facial paralysis due to a spitting cobra bite

Summary: 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 4.5-year-old boy who was bitten by a spitting cobra, resulting in considerable local swelling accompanied by a right-sided facial paralysis due to neurotoxicity by cobra venom. Presently, surgical methods to recover facial paralysis include nerve repair, nerve grafting, nerve transfers, static slings, muscle transfers, and functional muscle transplantations. However, mime therapy consisting of neuromuscular retraining resulted in a good functional result with a moderate contour deficiency of the right cheek and a subtle paresis of the zygomatic muscles at 1 year and 9 months follow-up. The natural history of facial paralysis in our case shows that this condition can be transient and may resolve with mime therapy as a conservative measure

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). Results: The parasite clearance times (PCT)25%, PCT50%, PCT75% and PCT90% were all significantly shorter for patients treated with ET than for patients treated with parenteral quinine only. The shorter PCTs in the ET group were the result of a more rapid parasite clearance in the early phases after initiation of ET. Conclusion: No case fatalities were observed in the ET group. The complications that were observed with ET were more likely related either to the multiorgan dysfunction associated with severe malaria or to side effects of parenteral quinine rather than to the ET procedure. ET may be safely executed in a setting with intensive care facilities and availability of safe blood products and should be considered as a beneficial adjunct treatment to parenteral antimalarial therapy
