The efficacy and safety of extended adjuvant temozolomide following concurrent radio-chemotherapy among Egyptian patients with newly diagnosed glioblastoma multiforme.

Although concurrent radio-chemotherapy and adjuvant temozolomide (TMZ) treatment for 6 cycles has been established as a standard of care for newly diagnosed glioblastoma multiforme (GBM) patients, the recommended duration of adjuvant TMZ remains a matter of debate. Hereby, we aimed to report for the first time our experience from Upper Egypt through comparing survival and toxicity profile between two treatment modalities of adjuvant TMZ (> six cycles versus six cycles) and delineating factors of prognostic significance in Egyptian patients with newly diagnosed GBM treated by radiation therapy with concomitant and adjuvant TMZ. Between June 2016 and February 2018, the medical records of 121 patients were eligible to be retrospectively reviewed to extract the study relevant data.

Role of diffusion-weighted MRI in differentiating between benign and malignant bone lesions: a prospective study.

Aim: To evaluate the ability of diffusion-weighted magnetic resonance imaging (DW-MRI) to differentiate between benign and malignant bony tumours.

Materials And Methods: This prospective study was conducted from October, 2018 to December, 2019. The study included 62 patients (37 male and 25 female) with clinically suspected bony lesions referred to the Radiology Department.

Kirschner wire versus Herbert screw fixation for the treatment of unstable scaphoid waist fracture nonunion using corticocancellous iliac bone graft: randomized clinical trial.

Purpose: The study compared the impact of the Kirschner wires versus Herbert screw fixation on the rate of union, time to union, correction of deformity, and clinical outcome in adults with unstable scaphoid waist fracture nonunions without avascular necrosis.

Methods: We prospectively randomized 122 patients to undergo corticocancellous iliac bone grafting and internal fixation either with multiple Kirschner wires or Herbert screw. Radiographs, clinical outcome measures (pain, range of motion, and grip strength), and the Quick DASH score were taken pre- and post-operatively.

Radiofrequency Thoracic Sympathectomy for Sympathetically Maintained Chronic Post-Mastectomy Pain, a Preliminary Report: 6-Month Results.

Aim: Evaluation of the analgesic efficacy of radiofrequency thoracic sympathectomy for sympathetically maintained post-mastectomy pain syndrome (PMPS).

Methods: Patients with PMPS randomized to Group TS (n = 33) received radiofrequency thoracic sympathectomy, and those randomized to Group Sham (n = 33) received no radiofrequency current. Postoperative pain treatment consisted of duloxetine, pregabalin, and tramadol for both groups.

Can the route of Toxoplasma gondii infection affect the ophthalmic outcomes?

Ocular toxoplasmosis is the most common cause of retinochoroiditis worldwide in humans. Some studies highlighted the idea that ocular lesions differ according to the route of infection but none of them mimicked the natural route. The current study aimed to investigate the ophthalmic outcomes in congenital and oral routes of infection with Toxoplasma in experimental animals.

Large-scale mitochondrial DNA analysis of the domestic goat reveals six haplogroups with high diversity.

Background: From the beginning of domestication, the transportation of domestic animals resulted in genetic and demographic processes that explain their present distribution and genetic structure. Thus studying the present genetic diversity helps to better understand the history of domestic species.

Methodology/principal Findings: The genetic diversity of domestic goats has been characterized with 2430 individuals from all over the old world, including 946 new individuals from regions poorly studied until now (mainly the Fertile Crescent).

Bayesian inference of population expansions in domestic bovines.

The past population dynamics of four domestic and one wild species of bovine were estimated using Bayesian skyline plots, a coalescent Markov chain Monte Carlo method that does not require an assumed parametric model of demographic history. Four domestic species share a recent rapid population expansion not visible in the wild African buffalo (Syncerus caffer). The estimated timings of the expansions are consistent with the archaeological records of domestication.

A microsatellite survey of cattle from a centre of origin: the Near East.

Eight humpless cattle breeds from the Near East, three from Europe, one from West Africa and two zebu breeds from India were screened with 20 microsatellite loci. Breeds from the Near East revealed considerable levels of introgression from zebu cattle, which was apparent most in populations from the East and which declined in populations further West. This nonrandom pattern is suggestive of the introduction of zebu cattle from the East.
