Neurologic manifestations of the neglected tropical diseases.

BACKGROUND: The World Health Organization has identified 17 neglected tropical diseases (NTDs) that disproportionately affect the world's poorest populations. The neurologic aspects of many of these NTDs have received relatively little attention. METHODS: A review was performed in PubMed (MedLine) for each NTD by disease name, name of its causative organism, and neurology, neurosurgery, neurologist, brain, spinal cord, peripheral nerve, muscle, nervous system, encephalitis, meningitis, encephalopathy, stroke, neuropathy, and myopathy (1968-Sept. 2013). The Oxford Center for Evidence-based Medicine guidelines were used to determine the level of evidence of neurological involvement and treatment based on the reports identified. RESULTS: Neurologic manifestations were reported for all NTDs except yaws. Neurologic involvement was described in systematic reviews for four NTDs (Chagas disease, echinococcosis, rabies, cysticercosis) (levels 2a-3a), retrospective cohort studies for six (dengue, human African trypanosomiasis, leishmaniasis, leprosy, onchocerciasis, schistosomiasis) (levels 2b-3b), case series for one (foodborne trematodiasis) (level 4), and case reports for five (Buruli ulcer, dracunculiasis, filariasis, soil-transmitted helminthes, and trachoma). Level 1 evidence for treatment of neurologic manifestations of NTDs was found for human African trypanosomiasis, leprosy, and cysticercosis and level 2 evidence exists for treatment of neurologic involvement in Chagas disease. For the remaining NTDs, treatment of neurologic complications is described in case series and case reports only. CONCLUSIONS: Neurologic manifestations of NTDs cause significant morbidity and mortality, although limited evidence exists on how best to treat these neurologic complications. Increased awareness of neurologic manifestations of the NTDs can increase their early identification and treatment, contributing to ongoing elimination and eradication campaigns.

Reportable neurologic diseases in refugee camps in 19 countries.

BACKGROUND: Approximately one-third of refugees worldwide live in refugee camps. Selected neurologic diseases are actively reported in some refugee camps. METHODS: The United Nations High Commissioner for Refugees monitors health visits in refugee camps with the assistance of more than 25 partner organizations using standardized case definitions. Neurologic diseases were selected and searched for the years 2008 to 2011. The number of health care visits for a neurologic disease was calculated and divided by the aggregated number of reporting months available for each refugee camp ("visits per camp-month"). RESULTS: Five neurologic diseases were reported from 127 refugee camps in 19 countries. Visits for chronic, noncommunicable diseases including epilepsy (53,941 visits in 1,426 camp-months, 48% female) and cerebrovascular disease (4,028 visits in 1,333 camp-months, 51% female) far exceeded those for neurologic infectious diseases (acute flaccid paralysis/poliomyelitis, 78 visits in 3,816 camp-months, 42% female; leprosy, 74 visits in 3,816 camp-months, 66% female; meningitis, 477 visits in 3,816 camp-months, 51% female). In 2011, these diseases accounted for 31,349 visits globally with 91% of visits for epilepsy. CONCLUSIONS: Targeted programs addressing epilepsy and stroke among refugees in camps should become a priority and indicate that other chronic neurologic diseases that may be under- or misdiagnosed may also be common in refugee camps. Given that significant under-reporting is likely, our findings demonstrate the pressing need for coordinated preventive and interventional measures for epilepsy and stroke in refugee camps.
