          Abstract

          Background: Cutaneous leishmaniasis (CL) is an infectious disease of zoonotic characteristic; its etiological agent is a protozoan of Leishmania species. This infectious agent is transmitted to humans through a secondary vector, which is infected sand-fly. According to WHO report, Iraq is a country where cutaneous leishmaniasis is an emerging disease, especially, its rural areas are labeled to be the source of the infection and endemicity. Course of the disease and treatment is highly defined by the subtype of cutaneous leishmaniasis and its species.

          Methods: Data were collected from cutaneous leishmaniasis registry database of Erbil Dermatology Teaching Center in city of Erbil from August 2016 to August 2017. The collected data were descriptively analyzed for the clinical manifestations and the course of disease in the outbreak of this disease in Erbil governorate.

          Results: A total of 124 patients were enrolled in this study. Among them, 93 (75%) were male and 31 (25%) were female. Their age ranged from 2 years to 73 years, with the mean age of 30.7±11.3. The majority of the patients were members of army forces. The total number of the lesions was 325. The number of lesions being ulcerated at the time of presentation was 179 (55%) and non-ulcerated lesions 146 (45%). Time needed for improvement ranged from 1.5 to 4.8 months. Recovery time of cutaneous leishmaniasis lesions from time of onset to the remission ranged from 1.3 to 14.3 months.

          Conclusion: The complete recovery time of the CL lesions was longer than what has been mentioned previously in Iraq. Ulceration of the lesions depends on the diameter of the lesions, as increased diameter increases the possibility of the ulceration. The possibility of lesion ulceration increases with an increase in the diameter of the lesions. Considering the observations in different clinical patterns and course of this disease, further studies should be conducted to identify CL species.

          A Historical Overview of the Classification, Evolution, and Dispersion of Leishmania Parasites and Sandflies

          Background The aim of this study is to describe the major evolutionary historical events among Leishmania, sandflies, and the associated animal reservoirs in detail, in accordance with the geographical evolution of the Earth, which has not been previously discussed on a large scale. Methodology and Principal Findings Leishmania and sandfly classification has always been a controversial matter, and the increasing number of species currently described further complicates this issue. Despite several hypotheses on the origin, evolution, and distribution of Leishmania and sandflies in the Old and New World, no consistent agreement exists regarding dissemination of the actors that play roles in leishmaniasis. For this purpose, we present here three centuries of research on sandflies and Leishmania descriptions, as well as a complete description of Leishmania and sandfly fossils and the emergence date of each Leishmania and sandfly group during different geographical periods, from 550 million years ago until now. We discuss critically the different approaches that were used for Leishmana and sandfly classification and their synonymies, proposing an updated classification for each species of Leishmania and sandfly. We update information on the current distribution and dispersion of different species of Leishmania (53), sandflies (more than 800 at genus or subgenus level), and animal reservoirs in each of the following geographical ecozones: Palearctic, Nearctic, Neotropic, Afrotropical, Oriental, Malagasy, and Australian. We propose an updated list of the potential and proven sandfly vectors for each Leishmania species in the Old and New World. Finally, we address a classical question about digenetic Leishmania evolution: which was the first host, a vertebrate or an invertebrate? Conclusions and Significance We propose an updated view of events that have played important roles in the geographical dispersion of sandflies, in relation to both the Leishmania species they transmit and the animal reservoirs of the parasites.

            Control of the leishmaniases.

            (2010)
            This report makes recommendations on new therapeutic regimens for visceral and cutaneous leishmaniasis, on the use of rapid diagnostic tests, details on the management of Leishmania-HIV coinfection and consideration of social factors and climate change as risk factors for increased spread. Recommendations for research include the furtherance of epidemiological knowledge of the disease and clinical studies to address the lack of an evidence-based therapeutic regimen for cutaneous and mucocutaneous leishmaniasis and post-kala-azar dermal leishmaniasis (PKDL). This report not only provides clear guidance on implementation but should also raise awareness about the global burden of leishmaniasis and its neglect. It puts forward directions for formulation of national control programmes and elaborates the strategic approaches in the fight against the leishmaniases. The committee's work reflects the latest scientific and other relevant developments in the field of leishmaniasis that can be considered by member states when setting national programmes and making public health decisions.

              An update on pharmacotherapy for leishmaniasis.

              Leishmaniasis broadly manifests as visceral leishmaniasis (VL), cutaneous leishmaniasis (CL) and mucocutaneous leishmaniasis. The treatment of leishmaniasis is challenging and the armamentarium of drugs is small, duration of treatment is long, and most drugs are toxic.
