Use of the Arndt wire-guided endobronchial blocker via nasal for one-lung ventilation in patient with anticipated restricted mouth opening for esophagectomy.

Functional separation of the lungs may be accomplished by several methods. Patient with restricted mouth opening has limited options for one-lung ventilation. We report the use of wire-guided endobronchial blockade, a new tool for achieving one-lung ventilation in a patient with restricted mouth opening requiring nasotracheal, fiberoptic intubation for esophagectomy and reconstruction with gastric tube substitution.     

Using a supervisory framework to support and evaluate a multiproject practice development programme

? The paper describes a multiproject practice development programme undertaken over a period of 1 year. ? The background and development of the programme are outlined, whilst attention is paid to the innovatory nature of the work, particularly the use of inductive, deductive and integrated approaches to both change implementation and project supervision. ? The programme was monitored throughout using different data sources and the paper uses evaluative material retrospectively to provide answers to organizational and professional difficulties which arose during the course of the programme. ? The authors conclude that the use of combinations of different models for practice development has potential, but requires careful supervision. ? They also recommend that those involved in practice development are made fully aware of its local or micropolitics, and develop strategies to deal with change before it occurs, not after it has taken place.     

Effects of haloperidol on motor and cognitive functioning in aged mice

The effects of haloperidol on motor and functioning and cognitive functioning were studied in young (3-5 months old) and aged (20-22 months old) male mice by examining haloperidol-induced catalepsy and haloperidol-induced decrements in performance on a radial arm maze. The aged mice were much more sensitive to these adverse effects of haloperidol than were the young mice. Studies of the distribution of radioactivity from [3H]haloperidol to the brain indicated that the differences in sensitivity to this drug were not due to pharmacokinetic differences. The results demonstrate that mice are suitable for studies of aging-induced changes in the behavioral effects of neuroleptic agents.     

Intracerebral bilateral symmetrical calcifications, demonstrated in a patient with pseudohypoparathyroidism

Bilateral Symmetrical Calcifications (B.S.C.) in cerebro represent calcium deposits usually found in the basal ganglia and/or dentate nucleus. They can be the result of diverse disorders, but can also present themselves without any underlying disease. Most often they are asymptomatic, but if the calcifications are extensive, extrapyramidal and cerebellar signs may arise. The following case concerns a patient with pseudohypoparathyroidism. Besides the usual signs and symptoms found in this disease, the patient also showed extensive B.S.C. The etiology and clinical symptoms of B.S.C. will be discussed. Furthermore, attention will be given to the syndrome of the pseudohypoparathyroidism and the effects of hypocalcemia.     

Gaining insight into the Clinical Practice Guideline development processes: qualitative study in a workshop to implement the GRADE proposal in Spain

Background  

The GRADE method represents a new approach to grading the quality of evidence and strength of recommendations in the preparation of Clinical Practice Guidelines (CPG). In the context of a pilot study to assess the implementability of the system in Spain, we considered it relevant to gain an insight into the significance of the perceptions and attitudes expressed by the actual experts participating in the system try-out.
