Context: There are three families and 66 species of scorpions in Iran, some of these species are medically relevant, and their sting has caused public health problems. Thus, identification of the new geographical distribution of scorpions and thee new species in very important. The goal of this study was to identify the distribution maps of Iranian scorpions that are medically important according to the latest information. Evidence Acquisition: This present study included a review of all the articles related to Iranian scorpions published in ISI, PubMed, Scopus, ScienceDirect, and Google Scholar databases during 2008 - 2019, using the relevant MeSH keywords. The data were entered in an Excel file, and spatial distribution maps were prepared. Results: From the review of the related published documents, we found that there are 66 scorpion species in Iran, some scorpion names have been changed and new scorpion species have been added to Iranian scorpion fauna and the spatial distribution of some species has become wider. Conclusions: Considering the new distribution maps and data on Iranian scorpions, for scorpion envenomation treatment and control programs, these variations should be regarded.

The oral cancer in Brazil is considered an important public health issue. Despite almost a century of combat disease, with oncological assistance programs and prevention campaigns based public policies, the incidence of oral cancer in several regions is still high. The major goal of cancer prevention and control is a reduction in both the incidence of the disease and the associated morbidity and mortality, as well as improved life for cancer patients and their families. Low-income and disadvantage groups are generally more exposed to avoidable risk factors such as tobacco and alcohol consumption. These groups have less access to the health services and education that would empower them to make decisions to protect and improve their own health. Thus, cancer control programs are the most effective instrument to bridge the gap between knowledge and practice and achieve this goal. The authors report some key historical facts concerning the fight against oral cancer in Brazil, in addition to addressing the epidemiological aspects of disease.

After more than a century, the genus Lepthercus Purcell, 1902 is revised. Lepthercus dregei Purcell, 1902 and L. rattrayi Hewitt, 1917 are redescribed; with the female of L. dregei described for the first time. Nine new species of Lepthercus are described. A phylogenetic analysis with morphological characters using implied weights and parsimony as optimality criteria, suggests the separation of the genus in two clades. The first clade is formed by L. dippenaarae sp. nov., L. engelbrechti sp. nov., L. haddadi sp. nov., L. rattrayi Hewitt, 1917 and L. sofiae sp. nov., here denominated “Group haddadi”. The species L. confusus sp. nov., Lepthercus dregei Purcell, 1902, Lepthercus filmeri sp. nov., Lepthercus kwazuluensis sp. nov., Lepthercus lawrencei sp. nov. and Lepthercus mandelai sp. nov., form the second clade, here denominated “Group dregei”. The “Group haddadi” is characterized by males with a curved metatarsus I, and a swollen tibia I. The “Group dregei” is supported by the presence of small maxillary cuspules in males. A new diagnosis is provided for Lepthercus as well as an identification key for all species of the genus. New distribution maps for the genus in the country are also presented.

SUMMARY Dengue fever, a very old disease, has reemerged in the past 20 years with an expanded geographic distribution of both the viruses and the mosquito vectors, increased epidemic activity, the development of hyperendemicity (the cocirculation of multiple serotypes), and the emergence of dengue hemorrhagic fever in new geographic regions. In 1998 this mosquito-borne disease is the most important tropical infectious disease after malaria, with an estimated 100 million cases of dengue fever, 500,000 cases of dengue hemorrhagic fever, and 25,000 deaths annually. The reasons for this resurgence and emergence of dengue hemorrhagic fever in the waning years of the 20th century are complex and not fully understood, but demographic, societal, and public health infrastructure changes in the past 30 years have contributed greatly. This paper reviews the changing epidemiology of dengue and dengue hemorrhagic fever by geographic region, the natural history and transmission cycles, clinical diagnosis of both dengue fever and dengue hemorrhagic fever, serologic and virologic laboratory diagnoses, pathogenesis, surveillance, prevention, and control. A major challenge for public health officials in all tropical areas of the world is to devleop and implement sustainable prevention and control programs that will reverse the trend of emergent dengue hemorrhagic fever.

The large New Worldgenus Messatoporus Cushman is diagnosed, redefined, described, and its species revised. A total of 89 valid species are recognized, of which 65 are described as new. All previously known species are redescribed and illustrated. The following synonyms are proposed: M. jocosus (Provancher) and M. rufiventris Cushman under M. discoidalis (Cresson), syn. nov. and M. tricolor (Szépligeti) under M. variegatus (Szépligeti) syn. nov. The following new species are proposed: M. advenus, M. albiaterartus, M. allomeros, M. amarelus, M. amazonensis, M. amplithorax, M. andinus, M. anepomius, M. apiopharkis, M. argentinus, M. atlanticus, M. atrifoveus, M. aurantius, M. badius, M. basiflavus, M. bennetii, M. bicolor, M. bimaculatus, M. campanulatus, M. caxiuanensis, M. citreocephalus, M. complexifemur, M. concavivenus, M. convexus, M. copiosus, M. depressifrons, M. dialeipsis, M. dissidens, M. dominicanus, M. elektor, M. ellipsicavus, M. euryoikos, M. igneus, M. interceptus, M. keraiopetalus, M. laevilatus, M. latissulcus, M. longicaudis, M. longitergus, M. lordos, M. lunatus, M. maculiscus, M. matucanus, M. nigriangulatus, M. nigriscapus, M. nigriscutus, M. occidentalis, M. opacus, M. orientalis, M. paeneater, M. pallidus, M. paradoxus, M. paralissonotus, M. pleuriflavus, M. semialbiventris, M. semiaurantigaster, M. subalaris, M. tenuiorbis, M. tenuissimus, M. teutonicus, M. titans, M. unidentatus, M. unimaculatus, M. versicolor and M. xanthogaster spp. nov. As well, a lectotype is designated for M. townesi Alayo and Tzankov, and Messatoporus nigrispina (Cameron) is transferred to Prosthoporus Porter, comb. nov.. A key to species based on both sexes is also presented, and new distribution records and distribution maps are provided. The validity and relationships of the genus are investigated cladistically using 162 morphological characters for 27 species of Messatoporus and 105 outgroup taxa. Tree search was conducted using TNT under implied weighting, with values of 1–6 for the concavity constant (K). All analyses recovered Messatoporus as a monophyletic group, supported by 7–11 synapomorphies. The results also support the monophyly of the six studied genera of Osprynchotina, in a clade including also Dotocryptus Brèthes. Messatoporus is diagnosed by the combination of the following features: apicolateral corners of clypeus projected; mandible long and tapered, ventral tooth much shorter than dorsal one or indistinct; transverse sulcus at base of propodeum long and shallow; anterior margin of propodeum concave; posterior area of propodeum almost always transversely wrinkled; first metasomal spiracle placed approximately on midlength; median dorsal carina of first metasomal segment absent; ovipositor basally cylindrical, apically depressed, with ventral valve enclosing completely dorsal valve as a sheath. A second analysis including all species of the genus was performed SANTOS & AGUIAR 4 · Zootaxa 3634 (1) © 2013 Magnolia Press to evaluate the phylogeny at the genus level. The character set for that analysis included 104 characters considered of phylogenetic importance within the genus, and used the same tree searching protocol as the first one. A distinct and gradual transition is detected, from species more similar to the remaining Osprynchotina to a significantly different morphotype with several convergences with the Gabuniina. These convergences are interpreted as adaptations to host location and substrate perforation, and may be related to use of more deeply concealed hosts.

Emerging zoonotic pathogens gain more attention due to the adverse effects on human and animal’s health and productivity. One of these zoonotic pathogens is Helicobacter pullorum (H. pullorum) which was firstly diagnosed in 1994. This bacterium is enterpathogenic in poultry and contaminates the carcasses meat during processing or improper handling. Human can get H. pullorum infection mainly through mishandling of contaminated carcasses or consumption of undercooked meat. Infection of H. pullorum in human is associated with gastroenteritis and hepatitis. Diagnosis of H. pullorum is very difficult as misdiagnosis with other enteric zoonotic pathogens like Campylobacter and other Helicobacter species is common. Unlike other types of Helicobacter, there are little information and few researches regarding prevalence, pathogenesis, diagnosis and control of H. pullorum infection either animals or human. Accordingly, this review article was prepared to give more details about H. pullorum sources of infection, pathogenicity, incidence in poultry and human as well as its treatment.

Cysticercosis affects cattle, which develop the larva of Taenia saginata after ingesting their eggs, which are released by humans. It is a parasite that is distributed worldwide. The use of geoprocessing allows a better definition of endemic areas and populations that face different levels of risk and thus creates a basis for specific control programs for each farming system. The objective of this study was to evaluate the epidemiological situation of bovine cysticercosis in four municipalities in the Triângulo Mineiro region (Romaria, Iraí de Minas, Grupiara and Douradoquara), with special attention given to the influence of the hydrographic network on the spatial distribution of the disease. The properties sampled (68) for laboratory and epidemiological analysis (questionnaire) were also georeferenced. The risk factors were analyzed using the ArcGIS 10.1 program. The animals were submitted to immunodiagnostic tests (enzyme-linked immunosorbent assay and immunoblot) for the diagnosis of bovine cysticercosis. After confirming the disease focus properties, the spatial distribution of the cases was analyzed in relation to the watershed of the region. The positive results for bovine cysticercosis on the properties of the municipalities of Romaria and Iraí de Minas were grouped together, which was a significant result (p < 0.01). Although the positive results for bovine cysticercosis in the municipalities of Grupiara and Douradoquara were randomly distributed (p = 0.27), the risk factor that proved to be statistically significant in the regression analysis for cysticercosis transmission was the water source from the river/stream. From the analysis of the map based on the hydrography of the region, it can be observed that for the distribution of positive cases for bovine cysticercosis in the properties, the main risk factor was the interference of the rivers and their tributaries that fed the municipalities sampled. This study allowed the identification of the prevalence of the taeniasis-cysticercosis complex in the properties of the sampled municipalities (53.84% in Romaria, 45.45% in Grupiara, 37.03% in Iraí de Minas and 35.29% in Douradoquara). The results from this study will help in the prevention and control of this zoonosis in the researched areas.

The outcome indicator framework helps tobacco prevention and control programs (TCPs) plan and implement theory-driven evaluations of their efforts to reduce and prevent tobacco use. Tobacco use is the single-most preventable cause of morbidity and mortality in the United States. The implementation of public health best practices by comprehensive state TCPs has been shown to prevent the initiation of tobacco use, reduce tobacco use prevalence, and decrease tobacco-related health care expenditures. Achieving and sustaining program goals require TCPs to evaluate the effectiveness and impact of their programs. To guide evaluation efforts by TCPs, the Centers for Disease Control and Prevention’s Office on Smoking and Health developed an outcome indicator framework that includes a high-level logic model and evidence-based outcome indicators for each tobacco prevention and control goal area. In this article, we describe how TCPs and other community organizations can use the outcome indicator framework in their evaluation efforts. We also discuss how the framework is used at the national level to unify tobacco prevention and control efforts across varying state contexts, identify promising practices, and expand the public health evidence base.
