Ciliated hepatic foregut cyst in a patient with renal cell carcinoma
Todd Straus, Vladimir Osipov
BMC Cancer , 2006, DOI: 10.1186/1471-2407-6-244
Abstract: We present in this case report a ciliated hepatic foregut cyst found incidentally in the setting of renal carcinoma. The patient was a man known to have a large renal mass, assumed to be cancer, and a liver mass suspicious for metastatic disease. This liver mass was cystic and upon further analysis showed ciliated epithelial lining. We describe the gross and histological appearance, as well as a brief discussion of ciliated hepatic foregut cysts.We report the first case of a patient with coexisting renal cell carcinoma and a ciliated hepatic foregut cyst. While this may represent a coincidental finding, a possibility of a neoplastic or non-neoplastic disorder associated with ciliated hepatic foregut cysts can not be completely ruled out.Ciliated hepatic foregut cyst (CHFC) is a rare cystic lesion of the liver found in all age groups. It was first described in 1857 by Friedrich who hypothesized its congenital derivation and was later named CHFC in 1984 by Wheeler and Edmondson [1]. Since its first descriptions less than 80 cases have been reported in the English literature. Histologically, the cyst is lined by ciliated psuedostratified columnar epithelium with scattered goblet cells. The wall of the cyst is composed of subepithelial connective tissue, 1–3 smooth muscle layers, and a fibrous outer capsule. Usually the cysts are found incidentally at autopsy or on radiology scans for unrelated conditions [2]. There are only six reported cases of CHFC in patients with cancer. The lesion rarely causes any symptoms, and when it does, usually is from mass effect on liver structures such as the portal vein [3]. For many years this lesion was considered completely benign, however there have been two reported cases of squamous cell carcinoma occurring within these cysts [4,5]. As a result, current ideas on how to manage a diagnosis of CHFC are changing. We describe the first case where CHFC was seen in a patient with renal cell carcinoma.The patient is a 63-year-old man who i
El estudio de la Prehistoria del Viejo Mundo en los Estados Unidos de América
Straus, Lawrence G.
Trabajos de Prehistoria , 1996,
Abstract: The teaching and study of Old World Prehistory are widespread and growing in the United States. However, actual research (especially excavation) is far more restricted among the many colleges, universities and museums that have specialists in particular aspects of this broad field. There is considerable interest notably in the Paleolithic/Mesolithic of Europe and Africa, generally associated with a paleoanthropological perspective. American researchers in anthropology departments are also heavily engaged in studies of terminal prehistory/protohistory in the Near East and Europe, with fewer specialists in the Neolithic per se. This article discusses the training, financing, organization, publication and theoretical foci for Old World prehistoric archeology in the U.S. It highlights the reasons for which American researchers usually approach the study of the Old World record from points of view that are different from and yet complementary to those of their European, African and Asian colleagues, who, unlike the Americans, feel they are directly studying their own national past. There is hopefully still a place for cooperative research involving Americans in full partnership with their Old World peers in the post-colonialist, post-Cold War world. La ense anza y el estudio de la Prehistoria del Viejo Mundo están difundidos en los Estados Unidos. Sin embargo, la verdadera investigación (especialmente la excavación) está mucho más restringida en las numerosas instituciones que tienen supuestos especialistas en algunos aspectos de este campo académico. Hay bastante interés principalmente por el Paleolítico/ Mesolítico de Europa y de áfrica, generalmente asociado con una perspectiva paleoantropológica. Hay también numerosos investigadores norteamericanos ocupados en el estudio de la Prehistoria final/Protohistoria del Oriente Medio y Europa, con menos especialistas en el Neolítico per se. Este artículo expone muy brevemente la formación, financiación, organización, publicación y enfoques teóricos de la arqueología prehistórica en los EE. UU. Subraya las razones por las cuales los investigadores norteamericanos se acercan al estudio del registro del Viejo Mundo desde unos puntos de vista diferentes pero sin embargo complementarios a los de sus colegas europeos, africanos y asiáticos. Espera que exista todavía un lugar para la investigación cooperativa que incluya a los norteamericanos en asociación plena con sus pares del Viejo Mundo en este mundo post-colonial y de la post-Guerra Fría.
Terminal Paleolithic and Early Mesolithic research at Abri Dufaure, Southwest France.
Lawrence Guy Straus
Munibe Antropologia-Arkeologia , 1987,
Abstract: Se presentan algunos resultados preliminares de la excavación y análisis del yacimiento Magdaleniense y Aziliense de Abri Dufaure en Sorde-l'Abbaye, al límite septentrional del País Vasco francés. Se hace balance de los hallazgos arqueológicos y faunísticos, de la crono-estratigrafía y de la estacionalidad de las ocupaciones humanas en el Magdaleniense Final (Aller d). También se hacen unas comparaciones con el yacimiento vecino de Abri Duruthy . Dufaure y Duruthy forman parte del importante conjunto de yacimientos tardiglaciares a la base del tajo de Pastou que domina un vado en el Gabe d'Oloron. Pastou representa un lugar de habitación y caza del reno invernal preferido de los grupos del final del Paleolítico en la región pirenáica occidental.
The American-European dialogue in the study of the Upper Paleolithic : some reflections on international collaboration in honor of Jesus Altuna
Lawrence Guy Straus
Munibe Antropologia-Arkeologia , 2005,
Abstract: Arqueologos norteamericanos se han implicado en la investigación del Paleolitico superior europeo desde los trabajos de G.G. McCurdy entre las dos guerras mundiales, pero especialmente desde las excavaciones de Hallam Movius en la Colombiere y l'Abri Pataud en los a os 1950, con una clara aceleración en las últimas décadas. Han surgido desafíos intelectuales al paradigma cultural-histórico dominante en los estudios del Paleolítico superior europeo, especialmente con la aparición de la arqueologia procesual en los EE.UU (y de la prehistoria económica en Inglaterra). Aunque todavía pueden existir elementos de la verdad en el argumento de que hay diferencias trasatlanticas en cuanto a la definición operacional del concepto de "cultura" y en la pretendida capacidad de los prehistoriadores paleolíticos de identificar grupos étnicos reales, hay convergencias crecientes (Y algunas pre-existentes) sobre cuestiones de la "teoría a nivel intermedio" de la metodología, e incluso de la difinición de los problemas aptos para la investigación. Un simposio organizado por el autor en el Congreso de la UISPP en Lieja intentó esclarecer las áreas de convergencia y de divergencia entre los investigadores norteamericanos y europeos y evaluar las contribuciones -positivas y negativas- de los primeros, a fin de continuar un debate trasatlántico fructífero.
Once more into the breach: Solutrean chronology.
Lawrence Guy Straus
Munibe Antropologia-Arkeologia , 1986,
Abstract: A pesar de unos intentos recientes, no es posible subdividir la unidad cultural - estratigráfica solutrense en fases cronológicas generales de una manera convincente a través de fechas del radiocarbono. La presencia, ausencia y frecuencia relativa de las puntas foliáceas supuestamente diagnósticas son variables entre los yacimientos y niveles individuales por razones funcionales, estilísticas o de muestreo. Existen diferencias interregionales en la edad por el radiocarbono del fenómeno Solutrense. Los intentos de reestablecer un esquema filogenético unitario cultural para el Suroeste de Europa en el período entre 21.000 y 17.000 BP son teóricamente estériles y condenados al fracaso.
Human occupation of Euskalerria during the Last Glacial Maximun: the Basque Solutrean.
Lawrence Guy Straus
Munibe Antropologia-Arkeologia , 1990,
Abstract: Se pasa revista a la evidencia de la ocupación humana del País Vasco durante el Ultimo Máximo Glaciar (ca. 21-16 kyr) y de los materiales solutrenses hallados en la región. Se examina la tipología arqueológica y los indicios de las estrategias humanas de adaptación. Se presenta un resumen de cada yacimiento conocido, junto con datos cronológicos y paleoambientales y unas conclusiones generales.
L'Abbe Henri Breuil: Archaeologist
Lawrence Guy Straus
Bulletin of the History of Archaeology , 1992, DOI: 10.5334/bha.02102
Abstract: In his otherwise excellent book, A History of Archaeological Thought, Trigger (1989: 156) makes only one passing reference in a half-sentence to the central figure in the development of Paleolithic prehistory in the first half of the 20th century -- and manages to get his name wrong, confusing Henri Breuil with his long-time, close colleague, Hugo Obenrnaie . Thirty years after his death, Breuil's role in the history of Old World prehistory required more serious consideration. He was a seminal figure not only in rock art studies, but also in the archaeology of at least France, Spain, England, Portugal, South Africa, and China. Before I had read Trigger's work or Sackett's (1991) critique of my supposed misinterpretation of Breuil's theoretical stance (e.g., Straus 1986, 1987), I had presented a review of Breuil's contributions in the 1991 Annual Snead-Wertheim Lecture in Anthropology and History at the University of New Mexico (Straus n.d.). The following is a brief summary of some of my conclusions.
The "Annales" School and Archaeology, edited by J. Bintliff, New York University Press, New York, 1991
Lawrence G. Straus
Bulletin of the History of Archaeology , 1992, DOI: 10.5334/bha.02204
Abstract: At a superficial level we could argue that application of concepts of the French "Annales" School of History to archaeology merely amounts to yet another semantic game, new fad, old wine in new skins. Some of the studies of this slim collection do seem a bit contrived, consisting of attempts to fit particular evidence (mainly from classical archaeology) into one or more of Braudel's three categories or temporal constructs: evenements, conjunctures and structures de longue duree. Does archaeology advance in its unending search for some new truth by merely borrowing and applying terms that have common in Continental history for at least a half century?
Die Skrif: Die lig vir alle wetenskappe
D. F.M. Straus
Koers : Bulletin for Christian Scholarship , 1979, DOI: 10.4102/koers.v44i1.1098
Abstract: Die kemvrae van hierdie tema sentreer rondom die aanduidinge: ‘die lig van die Skrif’ en ‘alle wetenskappe’. Daarom begin ons met enkele opmerkinge oor die aard van die Skrif-lig en vervolg dan met ’n besinning oor die betekenis daarvan vir die wetenskap.
Evidence for handheld electronic medical records in improving care: a systematic review
Robert C Wu, Sharon E Straus
BMC Medical Informatics and Decision Making , 2006, DOI: 10.1186/1472-6947-6-26
Abstract: To conduct the systematic review, we searched MEDLINE, EMBASE, CINAHL, and the Cochrane library from 1966 through September 2005. We included randomized controlled trials that evaluated effects on practitioner performance or patient outcomes of handheld electronic medical records compared to either paper medical records or desktop electronic medical records. Two reviewers independently reviewed citations, assessed full text articles and abstracted data from the studies.Two studies met our inclusion criteria. No other randomized controlled studies or non-randomized controlled trials were found that met our inclusion criteria. Both studies were methodologically strong. The studies examined changes in documentation in orthopedic patients with handheld electronic medical records compared to paper charts, and both found an increase in documentation. Other effects noted with handheld electronic medical records were an increase in time to document and an increase in wrong or redundant diagnoses.Handheld electronic medical records may improve documentation, but as yet, the number of studies is small and the data is restricted to one group of patients and a small group of practitioners. Further study is required to determine the benefits with handheld electronic medical records especially in assessing clinical outcomes.Patient safety is an increasingly important issue in care delivery. The Institute of Medicine report estimates that 44,000 to 94,000 deaths are caused annually from medical errors [1]. Studies estimate that 3–17% of inpatients experience adverse events significant enough to prolong hospitalization, cause significant morbidity, or lead to death [2-10]. Errors can be caused by a number of factors including lack of information about the patient or lack of knowledge about a therapy. In a study of errors in medication prescribing, 30% were related to knowledge in drug therapy and 29% were due to a lack of patient information[11]. Decreased uptake of the evidence by
