Abstract

Background: Uterine receptivity and implantation are complex processes requiring coordinated expression of molecules by zygote and uterus. Leukemia inhibitory factor (LIF) is one of the most important cytokines in the reproductive tract. Without expression of LIF in the uterus, implantation of a blastocyst cannot begin. Our objectives were to measure the leukemia inhibitory factor (LIF) concentration in serum with or without endometrial scratching in women with unexplained infertility. Methods: This study is a randomized control trial, carried out at the infertility clinic of Qena University hospital, South Valley University, Egypt. The study included 200 women with unexplained infertility divided into two groups: Group 1 included 100 patients undergoing endometrial scratching at mid luteal phase. Group 2 included 100 patients undergoing expectant management. Serum leukemia inhibitory factor (LIF) concentration was measured at mid-luteal phase of cycle and follow up of pregnancy occurrence in both groups. Results: LIF was significantly higher in the group of endometrial scratching compared to group 2. LIF was significantly higher in pregnant women compared to non-pregnant ones in both the endometrial scratching group and group 2. For the endometrial scratching group, LIF was a significant marker for successful implantation at cutoff point of 97.2 with sensitivity of 97.3% and specificity of 77.8% while PPV was 72% and NPV was 98. Conclusions: Endometrial scratching was associated with higher level of LIF and pregnancy rate. LIF was significantly higher in pregnant women with or without endometrial scratching.

Abstract

Out of 195 Camelus dromedarius examined only 19 were infected (9.7 %) with this parasite. The life cycle of T. sp. involves many morphologically distinct stages-more than described for any other genus in the Trypanosomatidae. This parasite was appeared for the first time in Camelus dromedarius at Assiut, Egypt. Most of stages of T. dromedarius (n.sp.) which were appeared in the blood of Camelus dromedarius are amastigotes stages. At the same time spheromastigots, epimastigote stages and trypomastigote stages with two shapes slender and broad. In experimental infection, the trypanosome was found to be transmissible to laboratory white mice, also metacyclic and amastigote formes were seen.

Abstract

Out of ninety eight of camels (Camelus dormadarius) examined, only forty eight (48.9 %) were found to be infected with blood protozoan parasites (Trypanosoma evansi, Theileria sp. and Babesia sp.). The higher incidence of infection were found in males (36.7%) whereas, (12.24%) in females. Microscopical examination revealed that longitudinal binary fission, the stumpy, slender forms of Trypanosoma evansi, trophozoites of both Theileria sp. And Babesia sp. Experimental infection revealed that both of Babesia and Theileria have a zoonotic importance for their transmissible to the experimental animals.

Abstract

The pediatric dentist plays a crucial role in the treatment and management of infants born with cleft deformities of the lip, alveolus, and palate. At New York University Langone Medical Center in New York City, 70% of infants with cleft lip/cleft palate (CLCP) are detected on prenatal ultrasound analysis. Thus, the role of the pediatric dentist can start as early as prenatal counseling. Nasoalveolar molding (NAM) is delivered during the first 3 to 5 months of life. During this stage of treatment, the pediatric dentist establishes the foundation of the “cleft dental” home and initiates the first stage of anticipatory guidance. Consequently, parents are educated and motivated to initiate oral hygiene care upon eruption of the first primary teeth. The purpose of this paper was to describe the role of the pediatric dentist in performing nasoalveolar molding and also describe its indications, appliance design, fabrication, biomechanics, complications, and patient management.
