Background: Thyroid surgery has undergone many changes during the past 2 decades, including the introduction of new surgical techniques such as endoscopic or video-assisted approaches, anesthesia care, intraoperative nerve monitoring and new hemostatic tools
Objectives: to assess the efficacy and safety of Harmonic Focus shears in total thyroidectomy compared with conventional surgical technique.
Patients and methods: prospective study conducted from October 2011 till January 2016, two handers and nine patients with benign and malignant thyroid diseases, scheduled for total thyroidectomy in a governor and private hospitals were enrolled randomly into 2 groups, group A consists of 105 patient who undergone a total thyroidectomy using a harmonic FOCUSTM , and group B consists of 104 patients who underwent total thyroidectomy with conventional surgical technique.
Results: Eleven patients had papillary thyroid carcinoma: 6 (5.7%) of them in group A and 5(4.8%) in group B. Eighty seven (82.9%) patients in group A had non toxic MNG, and 12(11.4%) patients had toxic MNG, 90 (86.5%) patients in group B had non toxic MNG while the other 9 (8.7%) had toxic MNG. Mean operative time was significantly lower in group A compared to Group B (100+/- 34 vs. 119+/- 30mins, respectively). In group A mean calcium level at first post-operative day was 8.36 +/- 0.54 mg/dl. In group B mean value was 8.12+/- 0.56 mg/dl. This difference was not statistically significant. There were no significant difference between the two groups concerning transient hypocalcemia requiring calcium and Vitamin D therapy: 11(10.5%) patients in group A versus 12(11.5%) in group B. No permanent hypocalcemia was found in both groups. Two patients had transient vocal cord palsy in group A(1.9%) versus 3 patients in group B (2.8%)
Conclusions: The HF is a reliable, comfortable and safe instrument alternative to knot tying technique, very suitable hand-piece for total thyroidectomy. It creates a clean, bloodless surgical field, and there is an advantage for the surgeon to use a single tool for both dissection and hemostasis. Moreover, the HF is a time-saving option, allowing for a significant reduction of operative time, without affecting parathyroid function, need for medical therapy, and hemostasis in the early post-operative period.
Binuclear copper, nickel, cobalt, manganese and mercury complexes of the Schiff base H2L (C40H28N2O4) obtained by condensation of 2-benzoyl benzoic acid with benzidine. The Schiff base and their complexes have been subjected to[ FT-IR, elemental analysis ,UV-Vis, 1H and 13C NMR ] spectral studies, molar conductivity, magnetic moment and HPLC measurements. All the complexes showed tetrahedral geometries with the general structure [M2(L)2]. Generality of the synthesized components offer antibacterial efficiency to (Staphylococcu saureus), (Escherichia coli),(Bacillus subtilis) and(Pseudomonas aeruginosa).
The nucleon momentum distributions (NMD) and elastic electron scattering form factors of the ground state for some 1f-2p-shell nuclei, such as 58Ni, 60Ni, 62Ni, and 64Ni
isotopes have been calculated in the framework of the coherent fluctuation model (CFM) and expressed in terms of the weight function lf(x)l2 . The weight function (fluctuation function) has been related to the nucleon density distribution (NDD) of the nuclei and determined from the theory and experiment. The NDD is derived from a simple method based on the use of the single particle wave functions of the harmonic oscillator potential and the occupation numbers of the states. The feature of the l
The electron correlation for inter-shells (1s 2p), (1s 3p) and (1s 3d) was described by the inter-particle radial distribution function f(r12). It was evaluated for Li-atom in the different excited states (1s2 2p), (1s2 3p) and (1s2 3d) using Hartree-Fock approximation (HF). The inter particle expectation values for these shells were also evaluated. The calculations were performed using Mathcad 14 program.
A square experimental arena with vegetation on one interior side was deployed in a Sharjah, United Arab Emirates desert. Individual darkling beetles (Coleoptera, Tenebrionidae) Akis subtricostata Redtenbacher, 1850 and Trachyderma philistina Reiche and Saulcy, 1857 were placed inside the arena at temperatures ranging between 27 - 49°C. Whether they chose the vegetated side of the arena or not was recorded, as well as how long it took for them to reach the vegetated side, if they chose it. Both species preferred the vegetated side at all temperatures, and the chance of them choosing the vegetated side increased significantly with increasing temperature (logistic regression, p = 0.0096 and p = 0.0003 for
