Abstract

Since 1940s, intake of Iodine 131 is a deeprooted postoperative therapy for malignant thyroid. However, clinical practice does differ significantly between hospitals. This paper presents a retrospective study of a clinical practice for patients diagnosed with thyroid cancer at King Abdulaziz University Hospital (KAUH). The aim of this study was to benchmark KAUH practice patterns against international guidelines. A total of 100 patients with thyroid cancer were included, 70% females and 30% males with median age of 42.5 and 43.5 years respectively. Cases were patients, diagnosed with thyroid cancer and treated with radioactive iodine at KAUH in Saudi Arabia between 2005 and 2011. Some additional patient’s data were excluded from the study because of missing information or lost to follow-up. Medical records included patient’s gender, age, clinical diagnoses, iodine dose, and the recurrence. Where, thirty-three percent (33%) of the patients had papillary carcinoma, (3%) had follicular carcinoma and (1%) had Hurtle cell tumors. All patients had their total/partial thyroidectomy at KAUH. Dose administered ranged from (50 to 300) mCi with the 61% receiving a dose of 100mCi. A statistical test, Chisquare test, were used to allow us to test for deviations of observed frequencies from expected frequencies. The medical record showed that 3% of the patient had died and 4% had a recurrence that was successfully treated by the time of the study. Moreover, the 5-year survival rates for patients with thyroid cancers was 93%. The thyroid cancer incidence and the I-131 practice in KAUH is consistent with international data and standards.

Abstract

In this research, we calculated the atomic properties of systems have been studied (N+ and O+2 ) for intra-shells (1s, 2s and 2p) using Hartree-Fock wave function. These properties included, one-particle radial density function, one-particle and inter-particle expectation values, inter-particle density function and expectation values of energies. All these atomic properties increase with atomic number, have highest values in 1s shell and lowest values in 2p shell. All results are obtained numerically by using the computer program (MathCad 14) because it able to calculation and plot functions. All atomic properties are calculated in atomic units.

Abstract

This article deals with stationary localized solutions of the (2D) two-dimensional complex Swift-Hohenberg equation (CSHE). Our approach is based on the semi-analytical method of collective coordinate approach. According to the parameters of the equation and a suitable choice of ansatz, the stationary dissipative solitons of the 2D CSHE equation are mapped. This approach allows to describe the influence of the parameters of the equation on the various physical parameters of the pulse and their dynamics. Finally, the major impact of spectral filtering terms on the dynamic of the solitons is demonstrated.
