The Prevalence of Gastrointestinal Parasites in Native Dogs in Palestine.

BACKGROUND: Dogs play an important role in transmission of parasites and zoonotic diseases, especially in developing countries. We aimed to investigate the prevalence of internal parasites in stray and pet dogs in Palestine. METHODS: Fecal samples were collected during the period between Jan to May 2019. A total of 150 fecal samples were collected and tested for parasites using sedimentation and flotation techniques. The targeted dogs were both pet dogs and stray dogs and were grouped according to gender and age. RESULTS: Although there was no significant difference in infestation between males and females, the prevalence rate of infestation in males was 63.1% compared to females 72.4%. Dogs of ages under one year had similar rate of infestation compared to older dogs with a rate of 67.3% and 67.4% respectively. Infestations were significantly higher (P<0.05) in stray dogs 81.4% compared to pet dogs 48.4%. The highest infestation rate was with Toxocara canis 46.0% followed by Dipylidium caninum 23.0%, Echinococcus spp. 14.0% ,Isosopora canis 9.0%, Ancylostoma caninum 8.0%, Giarda spp. 5.0%, Strongyloides spp. 4.0%, Trichuris vulpis 3.0%, and Cryptosporidium spp. 3.0%. CONCLUSION: Local dogs in Palestine, especially stray dogs, are infested with different types of intestinal parasites that may cause many common and non-common diseases to humans. To prevent the spread of these parasites, future public health should be proposed and applied by authorities to achieve a healthy status of the residents in the country. Health awareness spread among people about the seriousness of the diseases transmitted by dogs must also be activated.

Nuchal cord: impact of umbilical artery Doppler indices on intrapartum and neonatal outcomes: a prospective cohort study.

Background/objective: The purpose of this study is to investigate the use of a more biologic parameter for evaluation of the effect of nuchal cord tightness; the study of blood flow in the umbilical arteries of nuchal cord using Doppler ultrasonography. Methods: This prospective cohort study was conducted at Ain Shams University Maternity Hospital, Cairo, Egypt in the period between August 2015 and August 2017. Hundred primigravidas were recruited with nuchal cord diagnosed by Doppler ultrasonography; whereas the rest of the study population was included in the "Control group". Doppler velocimetry study was then performed on a free-floating loop of the umbilical cord and Doppler indices were calculated. Both groups were followed up during labor: intrapartum events, mode of delivery, and neonatal outcome were recorded. Results: Intrapartum fetal heart rate abnormalities were significantly more common in the nuchal cord group compared to the control group. The overall cardiotocography category was significantly more commonly reflecting abnormal fetal heart rate patterns in the nuchal cord group compared to the control group with 46.74% of the nuchal group patients falling within the "suspicious - pathological - need urgent intervention" categories. Intervention rate was significantly higher in the nuchal cord group than the control group (33.69 versus 21.84%). Moreover, incidence of intrapartum fetal heart rate abnormalities and intervention rate were significantly higher in the nuchal cord with abnormal Doppler subgroup compared to both nuchal cord with normal Doppler subgroup and the control group; with a calculated number needed to harm of 2.11. Conclusions: In view of these results, it might be concluded that umbilical cord tightness affecting fetal hemodynamics (expressed by changes in umbilical artery Doppler) might be a determinate factor affecting the intrapartum course.

The reproducibility of the novel utilization of five-dimensional ultrasound and power Doppler in the prediction of endometrial receptivity in intracytoplasmic sperm-injected women: a pilot prospective clinical study.

OBJECTIVE: The ultimate goal of this study is to reassess the five-dimensional implantation markers and pregnancy predictors on the day of human chorionic gonadotropin injection in the intracytoplasmic sperm injection and embryo transfer programs. DESIGN: A pilot prospective clinical trial. SETTING: The Assisted Reproductive Technology Unit of Ain Shams Maternity Teaching Hospital during the period from April 2014 to December 2017. PATIENTS AND METHODS: The study was conducted on 400 women undergoing intracytoplasmic sperm injection (ICSI). Those women were not older than 40 years, with normal uterine cavity and with no previous uterine scars. INTERVENTION: The ovarian stimulation protocol, used in this study for all patients, was the long protocol, before ovarian stimulation therapy, patients were instructed to use oral contraceptive pills from day 2 starting in the preceding cycle, then the standard regimen. On the day of hCG administration, 5D transvaginal ultrasound measurements were performed by the same observer after the patients had emptied their bladders. Measurements included endometrial volume and 3D power Doppler parameters, endometrial vascularization index, flow index, and vascularization flow index. RESULTS: The present study shows that endometrial volume ≥ 5 in the prediction of endometrial receptivity in ICSI patients had good sensitivity and low specificity in a group application; in an individual application it had good predictive negative value and bad predictive positive value. So it could be used as a good test to exclude success. Overall pregnancy rate was 40.5%; endometrial volume, flow index, vascularization index, and vascularization flow index were significantly lower in the nonpregnant group than those of the pregnant group. The area under curve in the receiver operating characteristic for three-dimensional ultrasound and power Doppler angiography parameters was statistically significant, but their values were suggestive but not conclusive in the prediction of endometrial receptivity in ICSI patients, no cutoff points with good diagnostic characteristics could be obtained. CONCLUSION: Five-dimensional ultrasound and power Doppler angiography is a useful exam to assess the endometrial receptivity in IVF/ICSI and embryo transfer cycles.

Multiple pregnancy and preterm labor.

OBJECTIVE: Multiple gestations are high risk pregnancies, which may be complicated by pre-maturity, low birth weight infants, pre-eclampsia, anemia, postpartum hemorrhage, intrauterine growth restriction, neonatal morbidity and high perinatal, neonatal and infant mortality. This study was carried out to determine the incidence and effect of multiple pregnancies on pre-term labor in tertiary care hospitals. METHODS: Retrospective case record analysis of 375 cases of multiple pregnancies that were reported at Armed Forces Hospital and King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia, between January 2000 and December 2001. The data was analyzed to determine the incidence of multiple pregnancies and its effect on pre-term delivery. RESULTS: The over whole incidence of twins was 14/1000 births. Premature labor in multiple pregnancies was 7 times greater than singletons (42% versus 6.4%). Almost half of multiple pregnancy cases were delivered by cesarean section (49% versus 14%). Pregnancy was induced in 34% of cases. Cervical cerclage was applied in only 8% of cases and betamemetics were administered to only 11% of cases. Fetal distress in labor, abnormal presentation and previous uterine scar were the main indications for cesarean section. Fifty percent had no antenatal complications, gestational diabetes complicated 16%, and anemia was reported in 22% of cases. CONCLUSION: Preterm delivery remains the most serious complication of multiple pregnancies. Multiple gestation children may suffer long term sequel of prenatal complications, including cerebral palsy and hearing disabilities. Every effort should be made to reduce the risk of multiple gestation and pre-term labor through proper control and close monitoring of fertility drugs, limiting number of embryo transfer to maximum of 3 or only 2, improving the socioeconomic status of expectant mothers, reduce cigarette smoking, relieve maternal stress, restriction of maternal activity, frequent contact with health care personnel and treatment of any obstetric or medical disorders.
