Scorpions are one of the most venomous animals which cause serious public health problems. The sting of scorpions can sometimes be fatal depending on the scorpion species involved. So far, sixty-six (66) scorpion species have been identified in Iran. Annually, about 40-50000 cases of scorpionism are reported in Iran. Odontobuthus doriae and O. bidentatus are among the most medically important scorpion species in Iran, and they are very similar to each other in coloration, carination, and trichobotrial patterns. This morphometric study aimed to compare some of the important morphological characteristics in order to identify the key differences between these two species. A total of 45 morphological characters were measured using calipers and stereomicroscope, and 55 morphological characters and ratios (relative of length to width ratio of morphological characters of scorpions) were analyzed. The independent sample t-test in SPSS software (version 24) was used for the statistical analyses in this study. The mean total length, carapace width, length of fixed and moveable fingers, and chelicerae length of O. doriae were greater than those of O. bidentatus in our study area. The morphological measurements displayed a clear distinction between O. doriae and O. bidentatus in our study area; therefore, they can be used as morphological identification keys for distinguishing between these two species.

Background: The institutionalization of evidence-informed health policy-making (EIHP) is complex and complicated. It is complex because it has many players and is complicated because its institutionalization will require many changes that will be challenging to make. Like many other issues, strengthening EIHP needs a road map, which should consider challenges and address them through effective, harmonized and contextualized strategies. This study aims to develop a road map for enhancing EIHP in Iran based on steps of planning. Methods: This study consisted of three phases: (1) identifying barriers to EIHP, (2) recognizing interventions and (3) measuring the use of evidence in Iran's health policy-making. A set of activities was established for conducting these, including foresight, systematic review and policy dialogue, to identify the current and potential barriers for the first phase. For the second phase, an evidence synthesis was performed through a scoping review, by searching the websites of benchmark institutions which had good examples of EIHP practices in order to extract and identify interventions, and through eight policy dialogues and two broad opinion polls to contextualize the list of interventions. Simultaneously, two qualitative-quantitative studies were conducted to design and use a tool for assessing EIHP in the third phase. Results: We identified 97 barriers to EIHP and categorized them into three groups, including 35 barriers on the “generation of evidence” (push side), 41 on the “use of evidence” (pull side) and 21 on the “interaction between these two” (exchange side). The list of 41 interventions identified through evidence synthesis and eight policy dialogues was reduced to 32 interventions after two expert opinion polling rounds. These interventions were classified into four main strategies for strengthening (1) the education and training system (6 interventions), (2) the incentives programmes (7 interventions), (3) the structure of policy support organizations (4 interventions) and (4) the enabling processes to support EIHP (15 interventions). Conclusion: The policy options developed in the study provide a comprehensive framework to chart a path for strengthening the country’s EIHP considering both global practices and the context of Iran. It is recommended that operational plans be prepared for road map interventions, and the necessary resources provided for their implementation. The implementation of the road map will require attention to the principles of good governance, with a focus on transparency and accountability.

Background: Head lice infestation is known as a serious health problem in developing and developed countries. The prevalence of pediculosis in children and females is higher than others. The infestation may cause the absence of student from school and make their parents upset. The aim of current study was to evaluate the WHO recommended insecticides for control of head lice in Islamshahr health center. Methods: In the current study infested individuals were older than 6 years old and have been diagnosed with at least 3 head lice adult and 10 live nits from less than 0.7 cm scalp. The pediculicides was applied randomly among groups. Permethrin shampoo as a golden standard was used. Dimethicone lotion 4% and Ivermectin lotion was compared with it. This study was conducted on 179 infested people. Results of infestation were evaluated after one month of intervention. Different indicators such as: present of head lice adult or live nit, redness and irritation in head skin were invested. Results: All the participants were female and 72.6% of them were in the age group of 6-11. The result revealed that aging not only decreases the infection rate but also raised the recovery percentage. The results showed that 79.5% permethrin receiver, 83% of people who treated with Dimethicone lotion and 90.6% of Ivermectin receiver had no head lice. There was no significant difference among these three pediculicides. Conclusion: There was no significant difference among tested pediculicides. An appropriate pediculicide can be selected by training people.

Scorpions are among the most medically important arthropods in Iran, particularly northwestern areas. To date, five scorpion species, i.e. Mesobuthus eupeus, Mesobuthus caucasicus, Androctonus crassicauda, Hottentotta saulcyi, and scorpio maurus, have been identified. The family Buthidae is responsible for most cases of scorpionism in Iran. The Mesobuthus eupeus species belong to this family and is commonly distributed from Turkey to China, including Iran. Among these species, Mesobuthus eupeus is regarded as the most medically important species and responsible for most cases of envenomation in this area. Morphological differences between some species collected in the study area have been reported. The present study, thus, aimed to identify the subspecies of Mesobuthus eupeus in northwestern Iran. Scorpions were captured in the summer months from 37 localities in three northwestern provinces in Iran: West Azerbaijan, East Azerbaijan, and Ardabil. Scorpion collection was carried out using rock rolling and ultraviolet methods. A total of 376 specimens of Mesobutus eupeus (177males and 199 females) were collected and identified as Mesobuthus eupeus (98.4%) and Mesobuthus eupeus philippovitschi (1.6%). Owing to the findings of our study, M.e.philippovitschi has been added to the scorpion fauna of northwestern parts of Iran for the first time. Unlike M.e. eupeus which is widely distributed from plains to mountainous regions, M.e.philippovitschi has limited distribution and is found mostly along the borders with neighboring countries. This subspecies is the most medically important and most prevalent one in the region. The findings of the present study also provide the basis for future consideration of regional antivenom production for this medically important species.

Background: Anaplasmosis and Ehrlichiosis are the most important tick-borne diseases. This study was conducted in three cities of Kerman Province in Iran to investigate the circulation of the bacteria in ticks collected from sheep. Methods: Ticks were collected from animals using Srkj forceps and transferred to the Entomology lab in cold chain. After specimen’s identification, they kept at -70 ºC. Tick DNA was extracted using Bioneers DNA extraction kits followed by Nested PCR technique to amplify ribosomal 16S rRNA gene to detect Anaplasma infection in ticks. Results: 472 sheep were examined from which 349 ticks were collected and identified in laboratory using valid keys. Tick specimens belonged to two genera and four species; Hyalomma marginatum (62.47%) was the most frequent and Hylomma asiaticum (5.73%) showed the least abundance. The infestation rate to different tick species was different in three regions of Kerman Province. Observation revealed that 24 specimens (58.3%) were positive for Anaplasma. There is a significant difference between male and female infection rate. However, there is no significant difference between these variables in each of these cities. Conclusion: This study shows high infection rates to Anaplasma in hard ticks. It is essential for health and veterinary authorities and farmers to use appropriate strategies to control ticks to reduce the infestation.

Introduction: Animal bite is a public health problem in Iran and in the world, and despite the great progress in preventing and treating these cases, it has had high economic, social, and psychological consequences. This study aimed to investigate the epidemiological and geographical status of animal bites in Mazandaran province in 2007-2016. Methods: This was a retrospective and longitudinal study conducted in 2018. The population of the study was all animal bitten people in the geographical ar

Scorpion sting is a common medical emergency in Iran. The epidemiological features and control of such cases vary from south to north. This review will provide new information about the epidemiology of scorpion stings in different provinces of Iran. In this descriptive retrospective study, data on scorpionism including incidence rates, mortality as well as locality from 2002 to 2011were collected. Overall, 433203 victims of scorpion stings had been referred to health centers from of all of the 31 provinces. The incidence of scorpion stings in 100000 populations was from 54.8 to 66. The highest rate of scorpion stings occurred among the 25–34 yr old group. The highest incidence of scorpion stings during 2011 was observed in Khuzestan Province and the lowest number in Mazandaran Province. The peak number of human cases (scorpion stings) was recorded during May to August. Scorpion stings in Iran are high. It is necessary that physicians and health care professionals should be familiar with local scorpions, especially those that are potentially more dangerous than others, the effective treatment protocols, and supportive care as well as their control of scorpionism

We evaluated the prevalence and consequences of human myiasis among people involved in animal husbandry and butchers among 6 counties in Fars Province, Iran using a descriptive cross sectional survey. A semi-structured questionnaire was used to evaluate knowledge, community perceptions and practices. Three hundred two herders shepherds and butchers were included in the study. Eighty-eight point three percent of subjects had experienced myiasis during their job experiences. Seventy-one point five percent had become infected in barns. Pharyngeal myiasis was reported by 87% of subjects. The most likely cause of myiasis in subjects was the sheep botfly, Oestrus ovis (Diptera: Oestridae). Age and job experiences did not have an effect on the knowledge and practice regarding myiasis of subjects. Academic educational level had no significant effect on knowledge but did have a significant effect on practices. A myiasis education program needs to be created to better control and prevent this problem.

Human head lice, Pediculus (humanus) capitis, infest people worldwide and are most prevalent in children. The aim of this study was to determine the prevalence of head lice, in relation to socioeconomic status of the family and hygienic practices in the home. The prevalence rate was determined in 27 primary schools that had 810 students in Sanandaj city who were selected by multistage, systematic random sampling. A total of 38 students from all grades were infested with different rates of infestations. In addition, standard questionnaire recorded information about demographic features of each student were fulfilled. Children aged 10-11 years were the most frequently affected, there was a significant relationship between head louse infestation, family income and parents education level (alpha=5%). Pediculosis is a public health problem in many parts of the world. Pediculosis was found to be more prevalent among children of fathers with lower level of education and socioeconomic status, it is necessary to give health education to families in order to prevent pediculosis in this area.

To carry out the distribution survey of hard ticks of livestock in Boeen Zahra and Takistan counties of Qazvin province from April 2010 to September 2010. Nearly about 2 638 sheep, 461 goats and 318 cattle of 38 herds in different geographical areas were searched for tick infestation. The species compositions collected from the livestock of Boeen Zahra and Takistan were Haemaphysalis concinna (0.63%), Haemaphysalis sulcata (12.66%), Hyalomma anatolicum (3.80%), Hyalomma asiaticum (3.16%), Hyalomma detritum (5.70%), Hyalomma dromedarii (28.48%), Hyalomma marginatum (13.29%), Hyalomma schulzei (1.89%), Rhipicephalus bursa (3.16%) and Rhipicephalus sanguineus (3.16%), and for Takistan's livestock were Hyalomma dromedarii (9.86%), Hyalomma marginatum (13.29%), Hyalomma schulzei (1.89%) and Rhipicephalus sanguineus (3.16%), respectively. Hard ticks compositions in different topographic areas were different. Hyalomma species had the most prevalence in the areas. The veterinary and public health investigation of the above species should be taken.
