Giant Appendicolith in Acute Exacerbation of Chronic Appendicitis: Case Report and Literature Review  [PDF]
Alberto Manuel González Chávez, Ricardo Ray Huacuja Blanco, Mario Andrés González Chávez, Silviano Ríos Pascual, Diego Abelardo álvarez Hernández, José de Jesús Curiel Valdés
Surgical Science (SS) , 2017, DOI: 10.4236/ss.2017.811051
Abstract: Right iliac fossa pain remains a challenge for clinicians, since it requires considering several differential diagnoses. Acute appendicitis continues to be one of the most important diagnoses to confirm or to rule out in acute abdominal pain, due to the associated morbidity and mortality. Currently, imaging studies contribute to increase diagnostic certainty, but sometimes reveal unexpected findings, which may further complicate the diagnosis and therapeutic decisions. We present the case of an unusual image finding in the right iliac fossa, a calcification suggestive of gallstone ileus, in the context of an acute abdomen with an unusual transoperative finding, whose definitive diagnosis by pathology, was also rare.

Agricultural Sciences (AS) , 2013, DOI: 10.4236/as.2013.46A013
Abstract: During 15 months the white shrimp (Litopenaeus schmitti) fishing zone was characterized ecologically through the obtaining, compilation and analysis of environmental and physicochemical variables, and modeled the distribution of the relative abundance (CPUE) obtained in 21 fishing sites according to the environmental structure defined by the studied variables. A two-way factorial ANOVA with interaction was used to examine the spatial (fishing sites) and temporal (months) dynamics of CPUE, and a principal component analysis (PCA) was used to discern the environmental structure of the study area. To determine if the environmental structure modeled the distribution of white shrimp, the CPUE values were superimposed on maps of the study area showing strata of the most important physicochemical variables identified by PCA. ANOVA confirmed that the CPUE differed significantly among months (F = 15.6; GL = 11; P < 0.0001) but not between fishing sites (F = 1.52; GL = 17; P = 0.1979); the interaction term was also not significant (F = 0.52; GL = 10; P = 0.8561). The superimposing of the CPUE on temperature and depth strata confirmed that white shrimp showed greater preference for intermediate temperatures and depths. Petróleos de Venezuela, S.A (PDVSA) contemplates the construction of a multiuse pipeline traversing the study area, by which the current environmental structure of the study area is prone to disturbance. Given the precedent effects represented by an aqueduct construction, it seems PDVSA should anticipate measures to minimize its impact on the fisheries of the zone, particularly on the white shrimp fishery.

Abstract: Introduccion: las lesiones tumorales del esófago tienen un creciente impacto sobre la población cubana, pero su tratamiento quirúrgico es riesgoso, en particular por los fallos anastomóticos. Objetivo: proponer una modificación a la esófago-gastrectomía de Ivor Lewis mediante una anastomosis látero-lateral con engrapadora. Métodos: se realizaron 19 esófago-gastrectomías de Ivor Lewis con la modificación propuesta de la técnica anastomótica entre enero de 2004 y diciembre de 2010. Resultados: de los pacientes operados, dos presentaron tumores en tercio medio, once en tercio distal, y seis en la unión esófago-gástrica o estómago alto invadiendo el esófago distal. No ocurrieron muertes quirúrgicas. Las complicaciones mayores fueron: tromboembolismo pulmonar de ramas finas, fibrilación auricular, neumonía, atelectasia . En ningún caso ocurrió dehiscencia o estenosis de la anastomosis. La estadía hospitalaria promedio fue de 11 días (mínimo 8, máximo 17). Conclusiones: la anastomosis esófago-gástrica látero-lateral por engrapadora lineal permite reducir la incidencia de dehiscencia y estenosis, lo que evita complicaciones en la intervención quirúrgica esofágica. Introduction: esophageal tumoral lesions have a growing impact on the Cuban population. However, their surgical treatment is risky, particularly due to the occurrence of anastomotic failures. Objective: propose a modification of Ivor Lewis esophagogastrectomy by means of a side-to-side anastomosis with stapler. Methods: nineteen Ivor Lewis esophagogastrectomies were performed with the proposed modification of the anastomotic technique between January 2004 and December 2010. Results: of the patients operated on, two had tumors in the middle third, eleven in the distal third, and six in the esophagogastric junction or the upper stomach invading the distal esophagus. No surgical deaths occurred. The following were major complications: pulmonary thromboembolism of fine branch, atrial fibrillation, pneumonia and atelectasis. No case presented anastomotic dehiscence or stenosis. Average hospital stay was 11 days (minimum 8, maximum 17). Conclusions: side-to-side esophagogastric anastomosis with linear stapler reduces the incidence of dehiscence and stenosis, preventing the occurrence of complications in esophageal surgery.

Abstract: Se realizó un estudio prospectivo y descriptivo del universo de escolares desde preescolar hasta 6to. grado de la Escuela Primaria "Jesús Menéndez," de la localidad de Alamar, en el período comprendido desde septiembre de 2000 hasta febrero de 2001, con el objetivo de estimar el comportamiento de los percentiles (pc) de tensión arterial, según edad y sexo, así como los factores de riesgo asociados. La muestra quedó constituida por 743 alumnos, a los cuales se les realizó un examen físico que incluyó peso, talla, toma de tensión arterial y una encuesta abierta. Con los datos obtenidos se dividió la población en 4 grupos de estudio según percentiles de tensión arterial: grupo I (<50 pc), grupo II (50-89 pc), grupo III (90-95 pc) y grupo IV (> 95 pc), según la literatura extranjera consultada, y se relacionaron con factores de riesgo. El mayor número de escolares estudiados se encontraban con cifras de tensión arterial ubicadas en canales menores al 50 pc (88,83 %), y el factor de riesgo que se encontró con mayor frecuencia fue el antecedente familiar de hipertensión arterial. Solo 6 escolares presentaron cifras de tensión arterial superiores al 95 pc.
