Control study of Musca domestica (Diptera, Muscidae) in Misan Province.

Background: Houseflies are the most common type of Diptera, specifically Muscidae, worldwide, representing more than 90% of all species. This family has over 170 genera and 4200 species, but a few are of medical significance. This study aimed to estimate and assessing the measures to control and prevent grow-up inside houses and flying of the housefly ( Musca domestica Linnaeus, 1758) in Misan. Methods: The study occurred over 12 months, from December 2020 to December 2021. Using plastic containers, Musca domestica were collected from all potential breeding sites in the study region (inside and around houses). Sticky oil paper and traps were used to collect the insects. The collected insects were transferred to sealed plastic containers and then to the laboratory of the Department of Microbiology.Out of 200 randomly selected houses, 150 (75%) contained insects. Light traps and sticky oil papers were the most effective control measures, with 26.7% and 25.9% of the Musca domestica collected from these methods, respectively. The ratio of male (233) to female (456) Musca was 1:2, with a significant difference between the frequencies (P<0.05). A large population of houseflies was collected during the hot season (501, 72.7%), whereas fewer Musca were collected during the cold months (188, 27.3%), with a strongly significant difference (P<0.05). The percentage of HI was 54.4%, the CI was 21.9%, and the BI was 79.9%. The overall larval densities (LD) were at a medium level. Conclusions: Misan has a high density of Musca domestica, with females being more prominent than males. Hot climate, humid sites, and dirty places are responsible for the breeding of houseflies. The overall larval density was medium. Therefore, the risk of transmitting infectious diseases by houseflies is high within the boundaries of Misan province, and effective control parameters should include measures like light traps and sticky oil.

Past, present and future of Trichomonas vaginalis: a review study.

Trichomonas vaginalis (TV) is the most common non-viral sexually transmitted infection (STI) microaerophilic protist parasite, which is the causative agent of trichomonosis. Globally, the estimated annual incidence is more than 270 million cases. It is correlated for several health problems including pelvic inflammatory disease (PID), pregnancy miscarriages, cervical carcinoma, prostatitis, prostatic adenocarcinomas, infertility, and the acquisition of human immunodeficiency virus (HIV). Most individuals infected with TV are asymptomatic. Metronidazole (MTZ) has been the treatment of choice for women. Currently, there is no effective vaccine against this pathogen despite efforts at vaccine development. Different socio-economic, demographic, behavioral, and biological factors are associated with the disease. Apart from its role as a pathogenic agent of diseases, it is also a fascinating organism with a surprisingly large genome for a parasite, i.e. larger than 160 Mb, and physiology adapted to its microaerophilic lifestyle. Particularly, the hydrogenosome, a mitochondria-derived organelle that releases hydrogen, attracted much interest in the last decades and rendered TV a model organism for eukaryotic evolution. According to the high prevalence and health consequences associated with TV, there is a requirement for improved screening programs in Iraq. The early diagnosis of asymptomatic diseases and effective treatment regimens are mandatory. Despite being highly prevalent of trichomonosis in the world, there is no review research published that solely focuses on T. vaginalis infections in Iraq.

An epidemiological study of cutaneous leishmaniosis in human and dogs.

Cutaneous leishmaniosis (CL) is a vector-borne parasitic disease with widespread on the communities throughout the Mediterranean regions and the Middle East, including Iraq. The study aimed for detection and diagnosis of CL in humans and dogs. This is an epidemiological study included six districts in Misan province, during the period from December 2019 to November 2020. All samples were taken from patients and owned-dogs. A total of 436 patients suspected with CL enrolled. A total of 237 owned-dogs were examined. The mean age of patients was (18.15Å}16.92) years. The rate of CL infection was high in Al-Amarah district. About 409 (93.807%) patients were diagnosed as a new case of CL, with no significant difference (P>0.05). The duration from bites by sandflies to the time of being diagnosed with CL ranged from 1 to 18 weeks. Patients owned-dogs (direct contact) were 167 (38.302%), and those with indirect contact were 123 (28.211%). Dogs manifested with clinical features of CL were 74 (27.715%), while those were asymptomatic (193, 72.284%). The lesions in dogs were severe (47, 63.513%), moderate (22, 29.729%), and mild (5, 6.756%). In conclusion, to the best of our knowledge, this epidemiological study of CL was conducted for the first time in Iraq.

Colorectal cancer epidemiology and clinical study in Misan / Epidemiologia do câncer colorretal e estudo clínico em Misan

ABSTRACT Introduction: Colorectal carcinoma is commonest cancer of gastrointestinal tract. It is represent third cancer in man worldwide beyond lung and prostate cancers. It is fourth cancer in woman beyond breast, lung and uterus cancers. Deaths from colorectal cancer are more in compare with other GIT cancers. Objective: The aim is prove epidemiological and clinical data of colorectal cancer. Method: Our study conducted in Misan Province, Iraq. The data collected from 2013 to 2016. Seventy one patients that found have colorectal cancer. Gender, age, residency, site of cancer, family history, past history, year of onset, smoking history, alcohol intake, presentation, staging and histopathology pattern are get. Results: Prevalence of colon and rectum carcinoma is 3.75%. The most age group affected was 51-60 years as 30.99%. The gender and residency of patients have no effect on cancer percent. Obesity, Family history, cigarette smoking and alcohol consumption risk factors. In 42.25% of patients had family history of cancer. Conclusion: Most common site of colorectal carcinoma left colon, which present in 61.97%. There is increase in new cases detection of colorectal carcinoma from 2013 to 2016. Advanced stages cancer were most common stages description as IIIA, IIIB, IIIC and IV in 12.67%, 16.90%, 19.72% and 15.49%. The common histopathological pattern is differentiated adenocarcinoma as 53.52%.

RESUMO Introdução: O carcinoma colorretal é o câncer mais comum do trato gastrointestinal. É o terceiro tipo de câncer mais observado no sexo masculino mundialmente, atrás dos cânceres de pulmão e próstata. É o quarto câncer mais observado no sexo feminino, atrás dos cânceres de mama, pulmão e útero. As mortes por câncer colorretal são mais comuns comparadas a outros cânceres do TGI. Objetivo: O objetivo do estudo é comprovar dados epidemiológicos e clínicos do câncer colorretal. Métodos: Nosso estudo foi conduzido na província de Misan, no Iraque. Os dados foram coletados de 2013 a 2016. Setenta e um pacientes apresentaram câncer colorretal. Sexo, idade, local de residência, local do câncer, história familiar, história pregressa, ano de início, história de tabagismo, etilismo, apresentação, estadiamento e padrão histopatológico foram obtidos. Resultados: A prevalência de carcinoma de cólon e reto é de 3,75%. A faixa etária mais afetada foi de 51 a 60 anos, com 30,99%.
