Abstract: a cross-sectional descriptive study of 340 persons assigned to two groups, with and without family history of diabetes mellitus type 2 (dm2), was carried out. the objective was to detect whether those persons with family history of dm2 had more hyperinsulemia, metabolic syndrome, associated cardiovascular risk factors and target organ lesions, expressed in left ventricle hypertrophy, than subjects without diabetes family history. the result was that hyperinsulemia was present in 96 patients with family history of dm2 (56,5 %) and significance level of p= 0,001. metabolic syndrome was more frequent in subjects with family history of dm2 (90) for 52,9 % of cases and p= 0,000. hypertriglyceridemia was both the most noticeable marker of the metabolic syndrome and the most statistically significant risk factor in subjects with family history of dm2 (96 , 52,9 % of cases and p= 0,000). left ventricle hypertrophy was associated as target organ lesion expression to subjects with family history of dm2 (36: 21,2 % and p=0,043). it was concluded that subjects with family history of dm2 are more likely to have hyperinsulinemia, metabolic syndrome, cardiovascular risk factors and target organ lesions than those persons without such a family history of dm2.

Abstract: the pheochromocytoma is a tumor of the chromaffin cells that may be located in territories derived from the neural crest or in the way these cells follow to their definitive localization. generally, they are located in the abdomen (90 % of the cases), particularly in the suprarenal glands and in zuckerkandl's organ. they may cause a wide variety of symptoms due to their capacity for secreting catecholamine, specifically noradrenalin and adrenaline in variable and intermittent amounts. clinically, they may be asymptomatic or appear with paroxistic arterial hypertension, or permanent with or without paroxisms, accompanied with the classic triad of headache, hyperhydrosis and tachycardia. according to the above-mentioned, it was decided to present a clinical case of a 40-year-old male patient with history of apparently essential controlled arterial hypertension of several years of evolution, with the diagnosis of apparently non-functional incidental right suprarenal tumor that after presurgical abdominal palpation began with a paroxistic hypertensive severe crisis. the patient was prepared with an alpha-blocker and he was operated on. a pheochromocytoma of the right suprarenal gland was confirmed in the anatomopathological report.
Piebaldismo en un recién nacido. Leucodermia rara Piebaldism in a newborn child. A rare leukoderma
Noemí Bárbara Cabrera Domínguez,Gloria Breto Rodríguez,Marelis Castro Márquez,Mirka Rosa Torres
Revista de Ciencias M??dicas de Pinar del R?-o , 2013,
Abstract: El piebaldismo es un defecto genético infrecuente donde las anomalías en la pigmentación de la piel se restringen al pelo y a la piel, aunque se han hallado ciertas similitudes con fenotipos de otras enfermedades. Se presenta el caso de un recién nacido del sexo masculino, raza blanca, hijo de matrimonio no consanguíneo con historia de piebaldismo familiar, que desde el nacimiento presenta un mechón de pelo blanco frontal acompa ado de parches de piel blanco a nivel de la frente y el tronco. Se realiza una caracterización clínica de esta enfermedad hereditaria, donde el defecto genético se ha encontrado en el gen kit (cromosoma 4q12); se realiza una valoración conjunta con la consulta de Genética Clínica y se realizan los estudios pertinentes. Se ofrece una revisión actualizada sobre el tema. Se presentan además fotografías del caso. Piebaldism is an uncommon genetic defect where anomalies in skin-pigmentation are limited to hair and skin, though some similarities to phenotypes of other diseases have been found. A case of a male, Caucasian newborn child, from non-consanguineous parents with family history of Piebaldism was examined; the child presented a white forelock with patches of hypomelanosis at forehead and trunk. A clinical characterization of this inherited disease was conducted where the genetic defect has been found in kit gene (chromosome 4q12), the assessment involved clinical and genetic studies, reviewing the most recent information of the topic. Photographs of the case were as well presented.
Building an Inclusive Definition of E-Learning: An Approach to the Conceptual Framework
Albert Sangrà,Dimitrios Vlachopoulos,Nati Cabrera
International Review of Research in Open and Distance Learning , 2012,
Abstract: E-learning is part of the new dynamic that characterises educational systems at the start of the 21st century. Like society, the concept of e-learning is subject to constant change. In addition, it is difficult to come up with a single definition of e-learning that would be accepted by the majority of the scientific community. The different understandings of e-learning are conditioned by particular professional approaches and interests.An international project, based on the participation of experts around the world, was undertaken to agree on a definition of e-learning. To this end, two main research activities were carried out. First, an extensive review was conducted of the literature on the concept of e-learning, drawing from peer-reviewed journals, specialised web pages, and books. Second, a Delphi survey was sent out to gather the opinions of recognised experts in the field of education and technology regarding the concept of e-learning with a view to reaching a final consensus.This paper presents the outcomes of the project, which has resulted in an inclusive definition of e-learning subject to a high degree of consensus that will provide a useful conceptual framework to further identify the different models in which e-learning is developed and practiced.

Inverse Problem on Heat Conduction in Heterogeneous Medium  [PDF]
Albert Schwab
American Journal of Computational Mathematics (AJCM) , 2014, DOI: 10.4236/ajcm.2014.41003

Under consideration is a nonclassical stationary problem on heat conduction in a body with the pre-set surface temperature and heat flow. The body contains inclusions at unknown locations and with unknown boundaries. The body and inclusions have different constant thermal conductivities. The author explores the possibility of locating inclusions. The article presents an integral criterion based on which a few statements on identification of inclusions in a body are proved.

Post Mid-Staffordshire Inquiries Reaction, in and about the National Health Service (NHS), England. The Missing Pieces: Organizational, Care and Virtue Ethics Perspectives  [PDF]
Albert Coleman
International Journal of Clinical Medicine (IJCM) , 2014, DOI: 10.4236/ijcm.2014.516131

The release of the Mid Staffordshire hospital report otherwise called the Francis report once again ignited the debate about the issue of abuse of especially vulnerable patients, while navigating the care pathway as inpatients in hospitals; within the National health service (NHS), England. Once more the official reaction from the NHS directorate is more “standards” to monitor failed standards in patient care. Of interest in the official responses so far, are the unheard voices addressing the issue of healthcare and organizational ethics concerns that need revisiting. This article seeks to revisit practice, systems and care issues leading to incidents of the type of the Staffordshire abuses, and the important but yet unheralded place of organizational and care ethics in helping to curb such abuses from re-occurring.

Road Traffic Accidents in Ghana: A Public Health Concern, and a Call for Action in Ghana, (and the Sub-Region)  [PDF]
Albert Coleman
Open Journal of Preventive Medicine (OJPM) , 2014, DOI: 10.4236/ojpm.2014.411092
Abstract: This paper highlights the increasing problem of road traffic accident (RTA) related morbidity and mortality in Ghana, and the public health measures needed to control the problem. Descriptive data in the public domain from statutory bodies and media houses reports on country RTA information, as well as academic papers on the problem, were used as source of information about the problem. The observed trend in Ghana indicates that RTA related fatalities and injuries continue to be increasing, as morbidity and mortality factors since the year 2000. Most of the remedial measures suggested in academic papers, and state agencies measures to curb the RTA trend in Ghana to date, have discussed the problem in terms of injury and safety issues/measures. This paper suggests that the increasing RTAs with associated morbidity and mortality in Ghana need to be looked at more as a public health problem and priority that requires prompt tackling using a public health problem orientated approach and measures, than just as a safety problem due to RTAs’, as is currently done.

Albert Sabban
Wireless Engineering and Technology (WET) , 2016, DOI: 10.4236/wet.2016.73010
Abstract: This paper presents measurements techniques of wearable antennas and RF medical systems in vicinity of human body. The antennas radiation characteristics on human body have been measured by using a phantom. The phantom electrical characteristics represent the human body electrical characteristics. The phantom has a cylindrical shape with a 40 cm diameter and a length of 1.5 m. The phantom electrical characteristics are similar to the human body electrical characteristics. The antenna under test was placed on the phantom during the measurements of the antennas radiation characteristics. The phantom was employed to compare the electrical performance of several new wearable antennas. The phantom was also employed to measure the electrical performance of several antenna belts in vicinity of human body. The results of antenna with thinner belt are better than the results of the same antenna array with thicker belt.
