A cross-sectional study was conducted from December 2017 to April 2018 to determine the prevalence and identify major species of ixodid ticks of cattle and tick burden of different sex, age, breed, and body condition of cattle. Standard physical and direct stereomicroscopy techniques were employed for identification of tick species. During the study period, a total of 353 cattle were examined for presence of ticks and around 447 ticks were collected. The study showed that 34.3% cattle were infested with one or more tick species. The study reported different species of ticks in the order of their prevalence: A. variegatum (46.3%), Rh. decoloratus (20.1%), A. cohaerens (15.7%), A. gemma (11.9%), and Rh. pulchellus (6.04%), respectively. The prevalence of tick infestation between different risk factors such as sex, age, and body condition of cattle was statistically significant ( p < 0.05 ). The overall male-to-female ratio of ticks was 2.29 : 1. Also, it was reported that, in A. variegatum, A. cohaerens, and A. gemma, the number of male exceeded that of female, but female number exceeded male number in case of Rh. decoloratus. The result also reported difference in attachment site preference, for example, Amblyomma genus was attached mostly to the scrotum/udder and axial and Rh. pulchellus was specified on the ear and perianal area, while Rh. decoloratus was non site selective. In conclusion, findings of this study suggest that ticks were the most important problems of cattle of the study areas. Therefore, the increasing threat of ticks warrants urgent strategic control including application of acaricides and creation of awareness among livestock owners about the veterinary importance of ticks for the integrated tick control.

A cross-sectional study design was conducted from November 2019 to April 2020 to identify the major ixodidae tick species and their prevalence in Sodo Zuria districts of Wolaita Zone in SNNPR of Ethiopia. A total of 3287(1701 male and 1586 female) adult ixodid ticks were collected from 500 animals during the study period. In this study three genera/sub-genus; Amblyomma, Rh. (Boophilus) and Rhipicephalus and four species were identified. From the three genera Amblyomma takes highest prevalence (45.29%). From four species identified, two of them belong to genus Amblyomma; Amblyommavariegatum and Amblyommacohaerence, one Boophilus; Boophilusdecoloratus and one Rhipicephalus; Rhipicephalusevertsievertsi. The quantitative hierarchy of the tick species was Rh. evertsi (14.40%), A. cohaerence (17.60%), A. variegatum (27.66%) and B. decoloratus (40.34%) in ascending order. Therefore, the result indicated that B. decoloratus (40.34%) and A. variegatum (27.66%) are the most abundant tick species of cattle in Sodo Zuria districts. Except B. decoloratus of which more females than male were collected, the number of male ticks counted were exceed those of female. The result of this study also demonstrated a significance variation (p<0.05) on infestation between local, cross and exotic breed cattle’s with highest prevalence in exotic breeds (75%),than both cross (56.2%) and local (68%) breeds and poor body conditioned cattle’s. Although a comparatively higher infestation was found on animals > 4 years compared with ≤ 4 year ones and between females than males and the difference was not statistically significant (p >0.05). Acaricide application was the main tick control method in the study area. Thus strategic application of acaricides might minimize the burden of ticks on the cattle of the study area.

A cross-sectional study was conducted from November 2010 to April 2011 to determining the prevalence of tick infestation, to identify the common tick species in cattle and to assess the major risk factors associated with the occurrence of tick species in Guba koricha district West Hararghe zone of Oromia regional state, southeast Ethiopia. Ticks were collected by searching and half body of animals using forceps on different regions of the animals’ body. A total sample of 384 cattle, 234 were found to be infested by one or more tick species an overall prevalence of 60.9%. The most predominant isolated ticks species in this study were R. pullchelus with isolation rate of 49.4% followed A. Varigatum with isolation rate of 30.3%, H. marginatum rufipes, the third predominant with isolation rate 11.8%.  However, A. gemma, H. trucatum and R. Evertsi-evertsi was the least isolate which accounts for 3.6%, 2.4% and 2.35% respectively. Age, sex and body conditions scoring were found to be important risk factors associated with tick infestation. The prevalence of tick infestation between age and sex was statistically significant (X2=32.3075, CI=0.1323358-0265075, P=0.000 andX2=5.117, CI=0.1953184-0.0061713, P=0.037) respectively. However, breed and body condition were not statistically significant (P>0.05). Hereof, Ticks are obligate, blood feeding ecto-parasites that cause severe damage to the hides and skins of domestic cattle due to this reduce the foreign exchange of the country; and transmit tick borne diseases. Therefore, effective tick control programs should be formulated and implemented at national or regional level.

Abstract Background Road traffic accident (RTA) is the eighth leading cause of death worldwide. Motorcycle-associated head injury is the leading cause of road traffic associated morbidity and mortality in developing countries. Even though the incidence and mortality of head injury from motor cycle crash is on the increase in developing countries, especially in the African continent, most of the studies published in the literature on this subject matter took place in the developed Western countries. Methods This is a retrospective cross-sectional study of data from patients managed in our institution between December 2014 and November 2016. Results One hundred and eighty-four patients were analyzed. None of the patients used safety helmet for protection. The mean age was 27.6 ± 17.2 years with male female ratio of 6.7:1. Lone crash by cyclists and collisions accounted for 66.8% and 33.1% of the cases, respectively. Passengers and riders comprised 75% of the patients, while 25% were vulnerable pedestrians. The most frequently abused substance by the patients was tramadol (65.52%). Severe head injury and pupillary abnormality were found in 23.9% and 45.5% of the patients, respectively. Cranial CT scan showed abnormalities in 40.2% of the patients. Surgery was done in 28.3% of the patients with mortality rate of 20.7%. Conclusions The use of motorcycle as a mean of transportation has caused significant negative impact on the society. Young people, who constitute the workforce, are majorly affected, and this invariably leads to a serious economic burden on the concerned families and communities.

Babesiosis caused by the Babesia species is a parasitic tick-borne disease. It threatens many mammalian species and is transmitted through infected ixodid ticks. To date, the global occurrence and distribution are poorly understood in questing ticks. Therefore, we performed a meta-analysis to estimate the distribution of the pathogen. A deep search for four electronic databases of the published literature investigating the prevalence of Babesia spp. in questing ticks was undertaken and obtained data analyzed. Our results indicate that in 104 eligible studies dating from 1985 to 2020, altogether 137,364 ticks were screened with 3069 positives with an estimated global pooled prevalence estimates (PPE) of 2.10%. In total, 19 different Babesia species of both human and veterinary importance were detected in 23 tick species, with Babesia microti and Ixodesricinus being the most widely reported Babesia and tick species, respectively. Regardless of species, adult ticks with 2.60% had the highest infection rates, while larvae had the least with 0.60%. Similarly, female ticks with 4.90% were infected compared to males with 3.80%. Nested-polymerase chain reaction (PCR) 2.80% had the highest prevalence among the molecular techniques employed. In conclusion, results obtained indicate that Babesia species are present in diverse questing tick species at a low prevalence, of which some are competent vectors.

We conducted a study to describe current patterns of drug-related behaviors, and to identify characteristics that may distinguish injecting drug users entering treatment from those out of treatment, in five Italian cities. Overall, 1,180 subjects were recruited — 568 entering treatment and 612 out of treatment. Male to female ratio was 6.6:1. The median age was similar in the two groups. A high proportion of injecting drug users recruited out of treatment had been in treatment at least once. HIV prevalence among injecting drug users entering treatment was not higher than that of those who were out of treatment. Furthermore, a large proportion of injecting drug users who still were out of treatment reported having adopted safe behaviors. The results of the study emphasize the need to implement outreach programs aimed at harm reduction.

Background: This study was done to identify risk factors that affect the morbidity and mortality of patients operated for a perforated peptic ulcer in a resource-limited setting.Methods: A two years (January 1, 2016 - December 30, 2018) retrospective cross- sectional study was done on patients admitted and operated for PPU at Yekatit 12 Hospital, Addis Ababa,Ethiopia.Results: A total of 93 patients were operated. The median age affected was 29 years (Range 15-75 years). Male to female ratio was 7.5:1. Chewing chat, smoking and alcohol use were seen in 22 (23.6%), 35(37.6%), and 34(36.5%), cases respectively. Only 23.6% gave previous history of dyspepsia. The median duration of illness was 48hours and the duodenal to gastric ulcer perforation ratio was 6.5:1. In majority of the cases (63.3%) the perforation diameter was <10mm (63.3%). Cellan-Jones repair of the perforations was done in 92.5% of cases. A total of 47 complications were seen in 25 cases. The total complications and mortality rates were 25(26.8%) and 6(6.5%) respectively. The most common postoperative complication was pneumonia (13.97%) followed by superficial surgical site infection (10.8%). Mortality rate was highest among patients >50yrs [AOR (95%CI) =2.4(2-30)]. Delayed presentation of >24 hours [AOR (95%CI) =4.3(1.4-13.5)] and a SBP <90mmhg [AOR (95%CI) =4.8(1-24)] were found to be significantly related with higher complication rate.Conclusions: Patients who presented early and immediate corrective measures were instituted had better outcomes while those seen late developed unfavorable out-come with significantly higher complications. Therefore, early detection and treatment of PPU is essential.

Introduction: Primary Central Nervous System (CNS) tumours constitute less than 2% of overall cancers in adults and are the second most frequently encountered tumours in children. Meningiomas form 24-30% of primary intracranial tumours. Most intrinsic brain tumours are soft and gelatinous in consistency, smear preparation can readily made which gives excellent cytological details when compared to frozen section as the latter produces ice crystal artifacts. Aim: To assess the diagnostic utility of squash cytological evaluation of meningiomas and its comparison with final histopathological diagnosis. Materials and Methods: The cross-sectional study was done at Thanjavur Medical College, Thanjavur, Tamil Nadu, India for period of three years from January 2015 to December 2017. Total of 54 clinically diagnosed and radiologically suspected case of meningiomas were selected. Smears were prepared from the biopsy samples sent in normal saline and stained by Haematoxylin and Eosin (H&E) method. The cytological features were noted and matched with biopsy findings. Descriptive statistics were used to analyse the results. Results: Total of 54 squash smears with male to female ratio was 1:1.5. Maximum number of cases were seen between 41- 50 years followed by 51-60 years. Complete concordance was obtained in 51 cases (94.44%) and partial concordance was noted in a case due to underestimation of malignancy grade in squash cytology. Out of 54 cases, two cases were found to be discordant with final histopathological diagnosis. Conclusion: Intraoperative squash cytology is easy, rapid, reliable and cost-effective technique for neurosurgical consultation with fairly high accuracy in diagnosing meningiomas.

The initiation of hemodialysis in patients with chronic kidney disease (CKD) requires vascular access formation. The choice of vascular access for individual patient depends on various factors however arteriovenous fistula (AVF) is conventionally considered to be the vascular access of choice. Once hemodialysis is initiated through a mature AVF, there is an ongoing need for surveillance of the AVF to ensure adequate function and prevent vascular access issues among which flow obstruction (both inflow and outflow) remains the most important. AVF stenosis can potentially lead to inadequate dialysis delivery and thrombosis thus leading to access loss. Physical examination and AVF Doppler ultrasonography (DUS) are useful for evaluation of stenosis in the  arteriovenous connection and the outflow tract. Periodic assessment of the AVF with Static Intra access Pressure (SIAPR) determination may be a reliable means of predicting vascular access stenosis. Material & Methods  A cross sectional study carried out at Department of Nephrology, Fatima Memorial Hospital, Lahore from July 2018 to December 2018. In total 113 patients were included, and all patients underwent SIAPR assessment and Doppler Ultrasound of AVF. Results Mean age of the patients was 56.81±9.38 years, male to female ratio of the patients was 1.8:1. In this study the SIAPR was suggestive of  stenosis in 87(76.99%) patients. The sensitivity, specificity and diagnostic accuracy of SIAPR against Doppler US of the AVF for detection of stenosis was 75.86%, 22.62% & 36.28% respectively Conclusion SIAPR has low specificity and diagnostic accuracy compared to Doppler US for detection of AVF stenosis.
