Appendiceal Colic in Children: Is It A True Surgical Entity?  [PDF]
Jason Marone, Domingo Alvear
Surgical Science (SS) , 2012, DOI: 10.4236/ss.2012.38079
Abstract: Background/Purpose: For decades children have been crowding the offices of Pediatricians’ and Pediatric Surgeons with a common complaint of unexplained recurrent right lower quadrant pain. For years the topic of appendiceal colic as a cause for this recurrent abdominal pain has remain controversial. This paper highlights the experience of a single surgeon over a 5 years period using an algorithmic approach to diagnose and treat children with appendiceal colic. Methods: This is a retrospective review of 31 consecutive cases of patients experiencing recurrent unexplained right lower quadrant abdominal pain for greater than three weeks. All patients were evaluated by a single surgeon at the same institution. The patients meeting the criteria for appendiceal colic had an elective open appendectomy. The data included was compiled by a retrospective chart review from Jan 1, 2006 to December 31, 2010. Results: Twelve percent or 31 of the 238 elective appendectomies done between Jan. 2006 to Dec. 2010 where done for appendiceal colic. Sixteen were females and 15 where males ranging in age from 5-17 years of age. Average duration of symptoms was 3 weeks to 5 years. All patients had previous work up most of which where inconclusive for an organic cause. All patients presented with colic and McBurney’s point tenderness. On pathological examination the presence of a fecalith, inspissated stool or fibrosis were the most common findings. A normal appendix was observed in 14% of the cases. 100% of the patients were symptom free with three months of operation. Conclusion: Appendiceal colic proves to be true in a small subset of patients presenting with unexplained right lower quadrant abdominal pain. A high index of suspicion coupled with a thorough history and physical exam is needed to identify these patients. Classically they will present with recurrent right lower abdominal pain at McBurney’s. In our experience an elective appendectomy has been curative.
Michael E. DeBakey and Denton A. Cooley— Mike, the Master Assembler; Denton, the Courageous Fighter: A Personal Overview Unforgettable Past Remembrances in the 1960s  [PDF]
Domingo S. Liotta
Open Journal of Thoracic Surgery (OJTS) , 2012, DOI: 10.4236/ojts.2012.23010
Abstract: Domingo S. Liotta discovered Assisted Circulation at the Department of Surgery of Baylor College of Medicine in Houston in 1961 and opened up a new medical therapy: Prolonged mechanical Cardiocirculatory Assistance (LVASs) for the treatment of Refractory and Irreversible Heart Failure. The American Society of Cardiology selected Liotta’s work for the “Young Investigator Award” granted in Denver in May 1962: ”This prolonged left ventricular bypass decompresses the left ventricle, reduces left ventricular work, decreases left ventricular wall tension and increases coronary circulation” (D. Liotta, D. A. Cooley, M. E. DeBakey et al. Prolonged assisted circulation during and after cardiac or aortic surgery: prolonged partial left ventricular bypass by means of intracorporeal circulation (Am J Cardiol 1963; 12: 399-405). Indeed, there is a lucky occurrence in science; I had the good luck to start this research at a moment when initially unrelated developments were actively taking place in cardiac surgery, long before any rigor or fine statistics were produced. The first observation was to recognize an interaction between the overstretched myocardial fibers and the result of cardiac assistance causing their shortening within the normal values when the excess of blood volume retained in the heart chamber was unloaded, and the second one was that the oxygen consumption of the heart (a measurement of its energy use) decreases during Cardiac Assistance. With the collaboration of Michael E. DeBakey, Liotta started the clinical experience of Cardiocirculatory Assistance and on August 6 1966 they succeeded in the first survival of a patient in postcardiotomy cardiogenic shock. Today, after 50 years, LVASs are in force in the medical practice worldwide and contrarily to transplantation practices, they have an unlimited future; they are continuously fed back by the scientific advances of general technologies. On April 4 1969 Cooley and Liotta implanted the first clinical Total Artificial Heart (TAH) as a bridge to heart transplantation. So far, this has been the case of TAH use in which the patient could be extubated and weaned off the ventilator the following morning. This is a sort of historical document. The venerable visit of Mike DeBakey to Argentina in 1996 was evidence of his majestic peace harmonized in the memory and veracity of useful years.
Determination of One Unknown Thermal Coefficient through the One-Phase Fractional Lamé-Clapeyron-Stefan Problem  [PDF]

Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.613191
Abstract: We obtain explicit expressions for one unknown thermal coefficient (among the conductivity, mass density, specific heat and latent heat of fusion) of a semi-infinite material through the one-phase fractional Lamé-Clapeyron-Stefan problem with an over-specified boundary condition on the fixed face \"\". The partial differential equation and one of the conditions on the free boundary include a time Caputo’s fractional derivative of order \"\". Moreover, we obtain the necessary and sufficient conditions on data in order to have a unique solution by using recent results obtained for the fractional diffusion equation exploiting the properties of the Wright and Mainardi functions, given in: 1) Roscani-Santillan Marcus, Fract. Calc. Appl. Anal., 16 (2013), 802 - 815; 2) Roscani-Tarzia, Adv. Math. Sci. Appl., 24 (2014), 237 - 249 and 3) Voller, Int. J. Heat Mass Transfer, 74 (2014), 269 - 277. This work generalizes the method developed for the determination of unknown thermal coefficients for the classical Lamé-Clapeyron-Stefan problem given in Tarzia, Adv. Appl. Math., 3 (1982), 74 - 82, which is recovered by taking the limit when the order \"\" .
Paradoxical Interplay of Viral and Cellular Functions
Esteban Domingo
Viruses , 2011, DOI: 10.3390/v3030272
Abstract: Some cellular editing functions can restrict the replication of some viruses but contribute to completion of the life cycle of others. A recent study has identified an isoform of the adenosine deaminase acting on RNA type 1 (ADAR 1) as required for embryogenesis, and as a restriction factor for a number of important RNA virus pathogens [1]. The dual implication of key cellular functions in the innate immunity against viruses, or, paradoxically, as mediators of virus replication is interpreted in the light of the concept of virus-host coevolution and tinkering proposed for general evolution by Fran?ois Jacob decades ago.

Avalia??o: Revista da Avalia??o da Educa??o Superior (Campinas) , 2008, DOI: 10.1590/S1414-40772008000200014
Abstract: this chapter analyzes, from a historical perspective, the evolution of higher education institutions in the last decades. the author also discusses the present challenges to achieve a successful reform of higher education after a long-lasting dictatorship. such a reform, argues the author, would be possible with an adequate harmony between the state and the institutions of higher education.
"For the Sake of the Children": South African Family Relocation Disputes
W Domingo
Potchefstroom Electronic Law Journal/Potchefstroomse Elektroniese Regsblad , 2011,
Abstract: Decisions by primary caregiving parents to relocate after divorce, thereby disrupting the non-primary caregivers’ right of contact with children or, where both parents have joint care, the denial of the other’s parental rights and responsibilities to care, give rise to cases which deal with relocation disputes. My paper deals with the development of South African family jurisprudence in this area. Since the Children’s Act does not provide any criteria for cases dealing with relocation I examine the different jurisprudential approaches/trends taken by our courts in dealing with relocation. I pave the way forward by making the argument that we need a general consistency in approach by our courts when dealing with relocation disputes. As our society becomes increasingly mobile, our courts will be faced with more frequent applications for local and international family relocations. I conclude by making the recommendation that despite the Children’s Act, we still need “guidelines” or perhaps a “Relocation Act” which works in tandem with the Children’s Act.
Citizenship, rights and justice in Latin America: The citizenisation-judicialisation of politics
Pilar Domingo
Revista CIDOB d'Afers Internacionals , 2009,
Abstract: The aim of this article is to study the phenomena of the judicialisation of politics and the citizenisation of the political discourse in Latin America in recent years. The article begins by presenting a definition of these phenomena, after which the author explains the phenomena through three different areas: the changes in civil society that have led to a discovery of law and the language of law; institutional reforms and specifically the reforms of judicial power in recent years, and the changes in the legitimisation discourse of the political system around the concepts of democracy and citizenship of rights.
