    Notes: Abstract The width of the presacral space and the thickness of the rectal valve were measured on lateral radiographs obtained during barium enema examinations performed on 182 Nigerian adult patients over a 5-year period (1980–1984). The mean width of the presacral space was 0.78 cm, the value in men being significantly higher than in women (p〈0.01). Although these values are similar to those reported among Caucasians, a wider range of normal values was obtained in this study. There is also no significant difference between the mean value of the rectal valve thickness of 4.3 mm obtained in this study and that obtained from previous studies.

    Notes: [Auszug] The 2004–05 eruption of Mount St Helens exhibited sustained, near-equilibrium behaviour characterized by relatively steady extrusion of a solid dacite plug and nearly periodic shallow earthquakes. Here we present a diverse data set to support our hypothesis that these earthquakes resulted ...

    Description / Table of Contents: Résumé Les auteurs se sont intéressés aux méthodes et aux résultats de la transplantation rénale chez le diabétique, effectuée dans un service consacré à la transplantation. Ils ne considèrent plus le diabétique comme un receveur à haut risque des lors que la transplantation est réalisée selon les méthodes les plus modernes. Le taux de la mortalité opératoire (30 jours) ne dépasse pas 3.5% et celui de la mortalité s'abaisse si une attention toute particulière est portée à l'état cardiovasculaire avant, pendant et après la transplantation. Le rein provenant d'un parent vivant représente le meilleur transplant en ce qui concerne la disponibilité, la fonction rénale après l'intervention et la fonction à long terme, cependant le rein de cadavre depuis l'emploi de la cyclosporin est susceptible de donner de bons résultats: le taux de la survie à 1 an du receveur atteint 98% et celui de la survie à 1 an du transplant est de 88%. Toutefois la proportion des pertes du transplant dues à la mort du patient consécutivement à des complications cardiaques et cérébrovasculaires reste relativement élevée chez le diabétique car elle atteint 35.8%. La récupération chez le diabétique qui a subi une transplantation rénale est moins complète que chez le sujet qui n'est pas diabétique, encore qu'elle soit toujours supérieure à celle obtenue par les autres méthodes de traitement de l'urémie chez le diabétique.
    Abstract: Resumen Las prácticas y resultados recientes en un centro de transplantes que sirve a una amplia proporción de pacientes diabéticos urémicos fueron revisados para resaltar ciertos aspectos del manejo moderno. El enfoque no es el de un recipiente de transplante renal de “alto riesgo”, sino más bien el de un recipiente que requiere una labor intensa en su manejo, por cuanto estos pacientes requieren atención a las múltiples complicaciones de su enfermedad primaria (propensión a la sepsis, retinopatía, neuropatía, enfermedad vascular central y periférica). Actualmente aceptamos todo paciente diabético que desee transplante, bajo los mismos criterios globales que se aplican a los pacientes no diabéticos. Mediante cuidadosa atención al estado cardiovascular perioperatorio, se puede lograr una mortalidad operatoria (30 días) de menos de 3.5% y minimizar la morbilidad. Los donantes intrafamiliares siguen ofreciendo ventajas en relación a la asequibilidad de los órganos, el precoz funcionamiento postoperatorio del riñón transplantado, y posiblemente, el mejor funcionamiento a largo plazo, pero ya los transplantes cadavéricos tratados con ciclosporina han revelado tasas competitivas de supervivencia del paciente a 1 año del 96% y de supervivencia del transplante a 1 año del 88%. Sin embargo, todavía la proporción de pérdida del transplante debida a muerte del paciente por causas inmunológicas, principalmente accidentes cardíacos y cerebrovasculares, sigue siendo alto en el diabético, del orden de 35.8%. La rehabilitación del diabético post-transplante es menos completa que la del recipiente no diabético, pero es claramente superior a la que se obtiene con métodos alternos de tratamiento en el paciente diabético urémico.
    Notes: Abstract The practices and recent results from a transplant center servicing a large proportion of uremic diabetics were reviewed to highlight modern management issues. The focus is taken off the diabetic as a “high-risk” renal transplant recipient and brought to bear on the laborintensive aspects of his or her management. With special attention to perioperative cardiovascular status, operative mortality (30 day) can be less than 3.5% and morbidity minimized. Living related donors continue to offer advantages in terms of organ availability, early postoperative function, and most likely long-term function, but in the cyclosporin era cadaver renal transplants have evolved competitive 1-year patient survival rates of 96% and 1-year graft survival rates of 88%. Still, the proportion of graft losses due to death of the patient from nonimmunologic causes, chiefly cardiac and cerebrovascular events, remains relatively high in the diabetic at 35.8%. Rehabilitation of the diabetic post-transplant is less complete than that of the nondiabetic transplant recipient, but is clearly superior to that of alternative modes of therapy for the uremic diabetic.

    Notes: Summary We present three lines of evidence which each suggest that intraspecific competition has significantly influenced the spacing patterns of Formica altipetens colonies. First, nearest-neighbor analysis of nest spacing patterns detected significant uniformity in six of eight plots. Second, there was a signifcant increase in the distance separating nearest neighbors as ant nest diameters increased. Third, ant nest density predicted substantial variation in the colony dispersion index, indicating the existence of a dispersion continuum at our study site.
