Introduction: French Guiana is an overseas region of France on the north coast of South America and is mostly covered by tropical rainforest. Most human settlements are located along the coast while some settlements are scattered across the hinterland. In 2001, the French public health service launched a telemedicine pilot project between the main hospital in Cayenne and remote health centers in French Guiana to tackle healthcare access inequalities. The aim of the present study was to review dermatology cases of the French Guiana telemedicine network to assess the use of telemedicine in dermatology, in order to evaluate its usefulness and propose ways to improve the system. Methods: A retrospective study was conducted on all dermatology cases referred between July 2015 and December 2016 through the French Guiana platform. The Model for Assessment of Telemedicine (MAST) methodology was used as recommended by the European Union. Results: A total of 254 cases were reviewed by dermatologists at Cayenne hospital over the 18-month study period, with a mean of 14 cases per month. All the 16 peripheral health centers used the telemedicine service during the study. In most cases (202/254, 80%), specialists provided a single diagnosis to the referrers. Infectious diseases represented the main reasons for requests (92/202, 46%) including 32% (29/92) of neglected tropical diseases like leprosy and cutaneous leishmaniasis. A total of 39% (100/258) peripheral centers answered the end-users' survey, and more than 85% found the answer delay was fast, the service useful and with an educational benefit. Overall, the accuracy of the diagnosis increased with the quality of the pictures provided, though the latter was good in only 60% (75/125) of the cases. Most patients for whom a teleconsultations has been required (234/254, 92%) have been managed in the peripheral health centers, while referring the patient to Cayenne was necessary for only 20/254 (8%). Conclusion: The telemedicine system in French Guiana appears to be an ...

International audience ; Background: Cutaneous Leishmaniasis (CL) is endemic in French Guiana but cases are usually sporadic. An outbreak signal was issued on May 15th 2020 with 15 suspected cases after a military training course in the rainforest. An outbreak investigation was carried out.Methodology/principal findings: Thirty cases were confirmed. Leishmania guyanensis was the most frequent species (90%). The most frequent presentation was ulcerative (90%). Lesions on the face and hands were frequent (40% each). Eight cases (26%) presented a poor outcome after treatment with pentamidine and required a second line with amphotericin B. Three of them required further treatments with meglumine antimoniate or miltefosine. Two spots within the training area were deemed as likely sites of contamination, due to illegal logging. The isolated Leishmania strains did not form a separate cluster. Participation in Week 13 of year 2020 was associated with infection (OR = 4.59 [1.10-19.83]; p = 0.016) while undergoing only the "Fighting" exercise was protective (OR = 0.1 [0-0.74]; p = 0.021). There was no association between infection and other risk factors at the individual level. The attack rate of Regiment B (14/105 = 13.3%) was significantly higher (OR = 4.22 [1.84-9.53], p = 0.0001) compared to Regiment A (16/507 = 3.2%). The attack rate during this training course (30/858 = 3.5%) was significantly higher (OR 2.29 [1.28-4.13]; p = 0.002) than for other missions in French Guiana during the same period (22/1427 = 1.5%).Conclusions: This outbreak could be explained by a combination of factors: climatic conditions around week 13, at-risk activities including night trainings, absence of impregnation, a lesser experience of rainforest duties in Regiment B and illegal logging attracting sandflies on military training grounds.

International audience ; Background: New world cutaneous leishmaniasis (NWCL) can be found in French Guiana as well as in several other parts of Central and South America. Leishmania guyanensis accounts for nearly 90% of cases in French Guiana and is treated with pentamidine isethionate, given by either intramuscular or intravenous injection. The military population is particularly exposed due to repeated missions in the rainforest. The purpose of the present study was to identify the factors associated with pentamidine isethionate treatment failure in a series of service members with L. guyanensis NWCL acquired in French Guiana. Method: All the French service members reported as having acquired leishmaniasis in French Guiana from December 2013 to June 2016 were included. Results: Seventy-three patients infected with L. guyanensis were included in the final analysis. Patients treated with IV pentamidine isethionate had better response rates than those treated with IM pentamidine isethionate (p = 0.002, adjusted odds ratio (AOR) = 0.15, 95% CI [0.04-0.50]). The rate of treatment success was 85.3% (95% CI [68.9-95.0]) for IV pentamidine isethionate and 51.3% (95% CI [34.8-67.6]) for IM pentamidine isethionate. Conclusions: The use of intramuscular pentamidine isethionate in the treatment of Leishmania guyanensis cutaneous leishmaniasis is associated with more treatment failures than intravenous pentamidine isethionate.
