Can elderly residents with memory problems be prepared for relocation?

Relocation of elderly clients between residential establishments can be unsettling, although good preparation can help reduce negative effects and contribute to successful transfer. However, it is less clear whether preparation is feasible for residents with cognitive deficits and clarification of this issue was the objective of the study. Results indicated that with the exception of those with severe cognitive deterioration, residents generally retained awareness of impending relocation and reported feelings appropriate to the situation. Implications for the types of preparation are discussed.

Does hospital rundown affect long-stay clients?

In order to examine what happens to long-stay clients who remain in hospital, a retrospective analysis of annual surveys between 1984 and 1992 was undertaken. Data were derived from the REHAB scale, which provides measures of patient Total General Behaviour (TGB) and Deviant Behaviour (DB), together with data from the Supplementary Information Questionnaire (SIQ). Results indicate that skills and behaviour, as measured by TGB, do not deteriorate as a function of continuous length of stay or increasing age. However, TGB for certain clients is adversely affected by a reduction in the level of structured activity occurring during major episodes of contraction leading up to closure. In contrast, DB, which is relatively high for this group, fluctuates independently of rundown. The implications for hospital services in transition are discussed.

Dexamethasone vs. placebo for cisplatin-induced emesis. A randomized cross-over trial.

A randomized cross-over trial of dexamethasone (10 mg I.V. before therapy, and 4 mg I.V. q 4 h X 6 doses) vs. placebo as antiemetic therapy was conducted in 19 patients receiving high-dose cisplatin. Sixteen patients and 32 treatment courses were fully evaluable. There was no significant difference between regimens in the number of emesis-free patients or the number of emetic episodes, though the duration of nausea symptoms may have been reduced. We conclude that dexamethasone as used in our trial is not an effective antiemetic in patients receiving cisplatin.

A prospective evaluation of indirect methods for detecting carotid atherosclerosis.

The statistical efficacy of three indirect techniques for noninvasive diagnosis of carotid artery disease was assessed in a prospective, blind study of 103 persons. Oculoplethysmography-carotid phonoangiography, periorbital Doppler examination and supraorbital photoplethysmography were acceptably sensitive only to carotid artery occlusions and preocclusive carotid artery stenoses exceeding a 75 per cent diameter reduction. Less pronounced lesions could not be reliably detected by any of the techniques used either singly or in combination. Supraorbital photoplethysmography proved inferior to the other methods because of its poor specificity rate.

Pelvic disruption in the polytraumatized patient: a management protocol.

This article reviews the experience with the management of 79 polytraumatized patients with pelvic fractures. The incidence of involvement of other systems was measured by the injury severity score. The average severity score was 33.5, and the mortality was 19%. Patients with a posterior disruption of the pelvis had a higher mortality, a higher "injury severity score," and required greater resuscitation efforts. Resuscitation of these patients requires efficient effective action. Adherence to our management algorithm, based on assessment of the patient's response, should help achieve that end.

Conducting tissues in univentricular heart of right ventricular type with double or common inlet.

Four specimens of univentricular hearts of the right ventricular type, three with two atrioventricular valves and one with a common valve, have been examined histologically to identify the atrioventricular conduction system. Three of the specimens were initially thought to have only one chamber within the ventricular mass, a chamber which had a right ventricular trabecular pattern. On detailed examination and with removal of blocks of tissue for histologic study, a second, rudimentary chamber was found in the posterior ventricular wall. This chamber had a trabecular zone of the left ventricular type and was connected with the main chamber only via a small defect in the septum which separated the two chambers. In all four cases the connecting atrioventricular node was dound in normal relationship to atrial markers and the penetrating bundle descended onto the posterior wall of the main chamber. In three cases it ran along the crest of the septum between the main chamber and rudimentary chamber, in relation to the septal defect. In two cases left bundle branch tissue was identified running into the rudimentary chamber. This pattern of conducting system is different from that previously identified in other varieties of univentricular heart and again underlines the importance of intraoperative mapping of the conduction system during surgery of the univentricular heart.
