Abstract: Aims: To describe the diagnostic aspects, surgical indications and post-operative complications of thyroidectomies performed in our department. Materials and method: A descriptive retrospective study that took place in the ENT Department and Cervicofacial Surgery of Gabriel TOURE University Hospital of Bamako. We did a comprehensive sampling of all goiter cases from January 2013 to December 2018. Were included in the study, the records of patients of all ages and genders, admitted into the ward and scheduled for thyroidectomy (partial or total). The exclusion criteria were incomplete hospitalization records. There were a total of 139 files were retained. Results: In 60 months, 139 cases were collected out of 1720 patients hospitalized for surgery, representing a hospital prevalence of 8.08%. The average age was 46.89 years. (123 women and 16 men). The socio-professional categories were dominated by housewives (68.34%). The reported functional signs were tachycardia, asthenia and other signs of dysthyroidism in 59% as well as signs of compression in 24.46%. In 72 cases or 51.80%, the patients consulted between 2 and 10 years of disease progression. Twenty patients or 14.39% had a history of familial goiter and 2 patients had a history of thyroid surgery. On physical examination the swelling was antero-cervical in 56.83% of cases. In 96 cases or 69.06% the glandular diameter was between 5 and 9 cm. In 2 cases or 1.43% we noted cervical adenopathy in the jugulo-carotid chain. Ultrasound, TSHus and fT4 were performed first-line and systematically in all our patients. Ultrasound objectified an appearance of multinodular goiter in 106 cases or 76.26%. In 60.43% of cases the patients were TI classes RADS 3, they were TI RADS 4A in 16 cases or 11.51%. CT scans were performed in 3 patients or 2.15% to specify the loco-regional extension, to look for possible lymph node invasion, and to compress or dipping the goiter. Surgical indication was placed in front of a multinodular goiter (GMN) in 106 cases or 76.26%, a single goiter in 11 cases or 7.9%, a single nodule greater than 3 cm in 17 cases or 12.23%, Basedow disease in 4 cases or 2.88% and a recurrence in one case 0.72%. We performed a lobo-isthmectomy in 56.11%, a total thyroidectomy in 20.14% of cases, subtotal in 20.86% of cases and total thyroidectomy with mediation-recurrent lymph node curage and bilateral jugulo-carotidien in 4 cases or 2.87%. Recurrent nerves were systematically searched and seen in all cases. Replacement therapy was indicated in all

Pravin Singare, Ram Lokhande
Natural Science (NS) , 2009, DOI: 10.4236/ns.2009.13025
Abstract: The ion exchange resin Amberlite IRA-400 in iodide and bromide form where equilibrated separately with the respective labeled iodide and bromide ion solution of different concen-trations varying from 0.005M to 0.100M in the temperature range of 32.0 ºC to 48.0 ºC. The dis-tribution coefficient Kd values calculated for iodide and bromide ion exchange increases with rise in ionic concentration of the external solution, however with rise in temperature the Kd values calculated where found to decrease. Also the Kd values calculated where higher for iodide exchange than bromide exchange. Among the different alternative techniques available for obtaining the Kd values, the radio-active tracer technique used in the present ex-perimental work offers high detection sensitivity. It is expected that the distribution coefficient data obtained from such experimental work will significant in environmental impact assessment on the disposal of radioactive waste.
Studies of Uni-Univalent Ion Exchange Reactions Using Strongly Acidic Cation Exchange Resin Amberlite IR-120  [PDF]

Natural Science (NS) , 2009, DOI: 10.4236/ns.2009.12015
Abstract: The selectivity behaviour of ion exchange resin Amberlite IR-120 for inorganic cations like sodium and potassium was predicted on the basis of thermodynamic data. The equilibrium constant K values calculated for uni-univalent ion exchange reaction systems were observed to increase with rise in temperature, indicating endothermic ion exchange reactions. From the K values calculated at different temperatures the enthalpy values were calculated. The low enthalpy and higher K values for K+ ion ex-change reaction indicates more affinity of the resin for potassium ions as compared to that for sodium ions also in the solution. The technique used in the present experimental work will be useful in understanding the selectivity behav-iour of different ion exchange resins for ions in the solution. Although the ionic selectivity data for the ion exchange resins is readily available in the literature, it is expected that the informa-tion obtained from the actual experimental trials will be more helpful. The technique used in the present experimental work when applied to dif-ferent ion exchange resins will help in there characterization.

Journal of Environmental Protection (JEP) , 2010, DOI: 10.4236/jep.2010.12016
Abstract: The present investigation deals with the assessment of pollution status along the wetland of Thane Creek, which has been subjected to a lot of pollution from the Asia’s biggest Thane—Belapur Industrial Complex located at the south of Mumbai harbor along the west coast of India. This paper advocates habitat conservation and ecological studies with special reference to the physico-chemical characteristics and heavy metal pollution in the soil along the creek area. In the present investigation, the pH, electrical conductivity, bulk density, alkalinity and chlorinity values recorded were observed to be high during dry seasons and low during rainy season. The soil samples were also analyzed for their heavy metal contents like nickel, zinc, cadmium, copper, iron, arsenic and mercury. It was observed that, the concentration of these heavy metals increases gradually in dry seasons, followed by sharp decrease during rainy season. These heavy metals have a marked effect on the aquatic flora and fauna which through bio magnification enter the food chain and ultimately affect the human beings as well. The present experimental data on heavy metal pollution in soil samples collected along Kalwa bridge of Thane Creek points out to the need of regular monitoring of water resources and further improvement in the industrial waste water treatment methods. If the present conditions continue for a long period, the creek may soon become ecologically inactive.

Open Journal of Physical Chemistry (OJPC) , 2011, DOI: 10.4236/ojpc.2011.12007
Abstract: The thermal degradation of some sulfonic cationites namely Amberlite IR-120, Indion-223 and In-dion-225 was investigated using instrumental techniques like thermal analysis (TG) and Scanning Electron Microscopy (SEM). Fourier Transform Infrared Spectroscopy (FTIR) was used to characterize the resins degradation steps. The sulfonic cationites undergo degradation through dehydration, followed by decomposition of sulfonic acid functional groups liberating SO2. The thermogravimetric analysis of above cationites at higher temperature up to 520oC, show mass loss of 61.61% and 25.43% respectively for Indion-223 and Indion-225, while Amberlite IR-120 cationite get burned off completely.

Journal of Electromagnetic Analysis and Applications (JEMAA) , 2009, DOI: 10.4236/jemaa.2009.13026
Abstract: Islanding detection is an essential function for safety and reliability in grid-connected distributed generation (DG) systems. Several methods for islanding detection are proposed, but most of them may fail under multi-source configurations, or they may produce important power quality degradation which gets worse with increasing DG penetration. This paper presents an active islanding detection algorithm for Voltage Source Inverter (VSI) based multi-source DG systems. The proposed method is based on the Voltage Positive Feedback (VPF) theory to generate a limited active power perturbation. Theoretical analyses were performed and simulations by MATLAB /Simulink /SimPowerSystems were used to evaluate the algorithm’s performance and its advantages concerning the time response and the effects on power quality, which turned out to be negligible. The algorithm performance was tested under critical conditions: load with unity power factor, load with high quality factor, and load matching DER’s powers.

Abstract: Renewable power generation is a suitable technology used to deliver energy locally to customers especially in remote regions. Wind energy based on induction generator situates in a foreground position in the total energy produced using renewable sources. In the last few decades, a new self- excitation generator was based on multi-stator induction strongly emerges. This article presents a systematic modelling, a detailed analysis and the performance analysis of self-excitation dual stator winding induction generator (SE-DSWIG). The modelling of the SE-DSWIG was done with taking in account the common mutual leakage inductance between stators and the magnetizing inductance, which played a principal role in the stabilization of the output voltage in the steady state. The generator feeds the end user emulated by an inductive-resistive load. In order to simulate the weather conditions’ variation, a step change of the prime mover speed was applied on the SE-DSWIG. A passive series and shunt compensator was used to mitigate the voltage sag and swell appeared in the power system due to wind variation and the lack of reactive power consumed by the inductive load.

Abstract: Objectives: We report two types of anatomical variations of the recurrent laryngeal nerve in two patients. Through these two patients we wanted to highlight our surgical approach of the recurrent nerve in an unusual position and to describe the surgical implication of these almost rare variations. Case report: patient aged 28 and 58 admitted for goiter. They underwent a right lobisthmectomy. Both recurrences were approached retrograde. The anatomical variations of the nerve concerned the non-recurrent laryngeal nerve in the first patient. In the second patient there were three anatomical variations, namely an extra laryngeal bifurcation of the nerve, a pre-vascular position of the nerve and a branch connecting the vagus nerve and the recurrent nerve. No recurrence nerve injury was noted. Conclusion: The anatomical variations of the nerve are numerous. A careful dissection is a guarantee of a good prognosis.
