Description of thelandros aegypti [nematoda: pharyngodonidae) from the egyptian spiny-tailed lizard, uromastyx aegyptia [squamata: agamidae) in egypt

Thelandros aegypti [Nematoda: Pharyngodonidae] isolated from the large intestine of the Egyptian spiny.tailed lizard, Uromastyx aegyptia, in North Sinai deserts, Egypt were described by means of light microscopy as a first description from this host in Egypt. 18 out of 25 [72%] of the examined specimens were naturally infected. The recovered nematodes characterized by the followings; the mouth bounded by three bilobed lips, the presence of three pairs of caudal papillae in male, the absence of gubernaculums, the post.equatorial vulva and the tail of female was suddenly constricted behind anus to form a terminal spike. Male was cylendrical with distinct posterior truncation, 3.0 [2.71-3.7] mm long; 0.24 [0.20-0.33] mm wide. Three pairs of anal Papillae were recorded; the first and the second were pre and perianal and the last pair immediately behind the rounded posterior region of the worm. The tail was narrow, sharply pointed and measured 0.052-0.072 mm in length with selender spicule measured 0.045-0.077mm long. Female was 4.34 [3.32-4.73] mm long, 0.29 [0.24-0.39] mm wide, vulva was post-equatorial, ovary was amphidelphic, the anterior part extended to the level of excretory pore and the posterior ovary extended posteriorly to the anal opening. Uteri were divergent. Egg was oval, slightly flattened and measured 65.4-79.2 Mum long and 44.3-74 Mum wide. The described parasite was compared with different species of the same genus from different hosts. It was found that morphometrically, the present species was more or less different from the comparable species and the only morphologically similar species was Thelandros aegypti

Assessment of multidetector CT virtual hysterosalpingography as a reliable modality for the evaluation of female genital system abnormalities

Background: virtual hysterosalpingography is a novel, noninvasive modality that combines the capabilities of multidetector CT with the established technique of hysterosalpingography to allow a simultaneous non-invasive evaluation of the entire uterine wall, uterine cavity, cervix and Fallopian tubes. The evaluation of the para-uterine pelvic structures is considered as a great advantage of the procedure that can be an alternative diagnostic technique in the infertility workup algorithm. Virtual hysterosalpingography with the reconstruction of two-dimensional, three-dimensional, and virtual endoscopic views allows a comprehensive evaluation of the female reproductive system with a single imaging test, it gives well-appointed anatomic information and a detailed characterization of the different pathologic processes. In comparison with HSG, US and MR imaging techniques that have been used for the diagnostic work-up of female infertility; virtual hysterosalpingography provides more detailed information about abnormalities of the cervix, uterus, Fallopian tubes and other pelvic structures and it may allow a more accurate evaluation of tubal patency. However, the resultant exposure of the patient to ionizing radiation is a relative disadvantage that must be weighed against the clinical purpose

Aim of the work: this study aimed to evaluate the role of virtual CT hysterosalpingography as a new noninvasive modality for the assessment of the uterus and the Fallopian tubes abnormalities

Conclusion: VHSG has the ability to integrate most of the advantages of the diagnostic studies methods in the diagnosis and evaluation of the infertile female. Whether it should completely replace the use of standard conventional HSG among the infertile females, or be used as a back up to HSG and indicated when questionable or abnormal findings are encountered

Predicative factors for pegylated interferon-alpha plus ribavirin combination therapy in Egyptian patients with chronic hepatitis cinfected with genotype 4

Hepatitis C virus genotype 4 is a common infection in Egypt and is the leading cause of liver disease. Most reports suggest that predicative factors for the efficacy of interferon alpha and ribavirin combination therapy for chronic hepatitis patients could be due to the mutations in the interferon sensitivity determining region. The present study aimed to investigate the predictive factors for combined pegylated interferon-alpha and ribavirin therapy for chronic hepatitis patients with HCV genotype 4. The study was carried out on forty patients with genotype 4 chronic hepatitis C receiving a weekly dose of 180 microg of PEG -IFN-alpha in combination with RBV for 48 weeks. HCV RNA serumviremia levels were determined by a real-time polymerase chain reaction. The RNA samples were genotyped using specific primers for HCV genotype 4, and the interferon sensitivity determining region was amplified using polymerase chain reaction and sequenced. The amino acid sequence of the ISDR was compared with the published sequence for HCV 4 [GenBank: ABD75831.1]. Our data revealed that twenty one patients were responders [R; 52.2%], whereas 19 patients showed no-response [NR; 47.5%] to the combined pegylated interferon-alpha plus ribavirin therapy. The values of RNA titer in both responder and non-responder groups were statistically significant and could be used a predictive factor for combined pegylated interferon -alpha plus ribavirin efficacy. Other factors, such as gender, age, and interferon sensitivity determining region subtype were not related to its efficacy. These data collectively suggest that HCV RNA titer is an important factor for predicting the efficacy of pegylated interferon alpha plus ribavirin combination therapy in Egyptian patients with chronic HCV genotype 4

Immediate loading of implants placed into fresh extraction sockets with peri-apical lesions without augmentation

The objective of the present study was to evaluate the clinical and radiographic outcomes of immediately placed Osteo Care implants into fresh extraction sockets of maxillary central incisor teeth with periapical lesions, without raising a flap and loaded immediately with the final abutments. All implants were restored immediately with provisional unsplinted acrylic resin crowns above their immediately placed final abutments. The final restorations were placed after 3 to 6 months. The parameters were reported immediately after implant placement and after 3, 6 and 9 months. The described technique included 20 patients of young age, with 3 cases failure. The present results showed promising data for immediate implantation and provisionalization to replace teeth with periapical lesions in the anterior maxilla. The technique applied in this study shortens treatment time and simplifies implant restoration for the dentist as well as, for the patient. It is evident that the success of this technique requires good case selection, atraumatic tooth extraction, achieving and maintaining primary stability
