Life events and social support in prediction of stroke outcome.

A prospective study of 252 patients (average age 73, range 26-95) admitted to a regional general hospital over a 12-month period was carried out. 241 patients had stroke verified by the initial neurological examination and CT scan, and of these baseline data were not available on 27%. 34% died before or were not willing or able to provide data at follow-up. 39% survived and completed the study. Prestroke life events and social support could not predict the outcome of stroke rehabilitation measured as survival, length of stay, functional recovery (Barthel's Index) or placement at the follow-up 12 months after the onset of stroke. Age and arteriosclerotic heart disease predicted poor survival at follow-up. Premorbid hypertension, stroke, diabetes, obesity, tobacco smoking, and alcohol consumption did not significantly influence the outcome. Problems in stroke rehabilitation research are discussed.

Gated intracoronary thallium201 scintigraphy: feasibility and potential clinical advantages.

Visualization of ventricular walls with true global motion and myocardial thickening is not possible with use of present scintigraphic techniques. When thallium 201 (201TI) is injected intravenously (IV), only about 5% reaches the myocardium. However, if 201TI is injected intracoronarily, 100% reaches, and approximately 88% localizes in, the myocardium, which results in higher count rates than when given IV, permitting acceptable acquisition times for gated true wall motion studies. The authors describe a new technique using intracoronary (IC) 201TI to acquire high count rate, high contrast, and short acquisition time in gated true wall motion studies. Thirteen patients were studied at rest with gated IC thallium. Six of these patients also had resting IV 201TI myocardial studies. After routine coronary angiography, 0.75 mCi of 201TI was injected into each coronary artery. Multiple sequential one-minute gated studies were obtained in LAO and RAO projections, followed by sequential five-minute images for two hours to determine 201TI redistribution kinetics. Regions of interest over segments of left and right ventricles and background permitted definition of temporal and spatial distributions. Three one-minute gated studies were summed with a total count of 2,100 K for a three-minute acquisition. Myocardium-to-background ratios were as high as 13:1 with a mean of 11.4:1 in the IC study compared with 2.3:1 in the IV studies. Washout half-time in normal myocardium was 95 +/- 5 min. The detectability and size of perfusion defects were different on gated diastolic and systolic, nongated, and IV studies. Questionable defects seen on nongated studies or after IV administration were easily noted on gated diastolic images.(ABSTRACT TRUNCATED AT 250 WORDS)

Bone metastases in primary operable breast cancer. The role of a yearly scintigraphy.

In 231 patients with primary operable breast cancer bone scintigraphies were performed yearly from the second to the 6th year until recurrence irrespective of localization was diagnosed, another cancer was detected, or the patient refused further follow-up or died. During the observation period (from 2 up to 7 years after surgery) 13 patients (5.6%) had bone metastases verified by X-ray or histology within 12 months after the last bone scintigraphy. The scintigraphy was positive in only 7 of these patients. The yearly incidence of bone metastases varied between 0.6 and 2.6%. Due to this low incidence and a low cost/benefit, we conclude that a fixed schedule of repeated scintigraphies in primary operable breast cancer patients otherwise free of apparent disease is not justified.

Glucagon in acute ureteral colic. A randomized trial.

The effect of glucagon administered as a bolus (1 mg) followed by a continuous infusion (2 mg/h) for 8 h and a placebo was compared in 37 adults with urographically demonstrated ureteral calculi less than 6 mm. The bolus injection was given 20 min after start of intravenous urography, and the infusion was initiated immediately afterwards. No effect on pain relief or passage of calculi was found. Nausea and/or vomiting were recorded significantly more frequently in patients who had glucagon than in patients who had the placebo. It is concluded that glucagon is of no value in acute ureteral colic.

Treatment of serious urological infections with cefotaxime compared to ampicillin plus netilmicin.

Fifty-nine patients with severe urinary tract infections were treated with either cefotaxime or ampicillin plus netilmicin in a controlled, open randomised study of the clinical and bacteriological effects. The patients responded favourably in both groups. The minimum inhibitory concentrations of cefotaxime against the isolates from blood were low for all bacterial strains except one (Streptococcus faecalis). Time to normalisation of temperature was significantly shorter in the cefotaxime group. The results suggest that cefotaxime is an effective and well-tolerated agent in the treatment of serious infections. However, the difference between the two groups was too small to allow preference of one procedure over the other.

Comparison of two endotracheal tube securement techniques on unplanned extubation, oral mucosa, and facial skin integrity.

OBJECTIVE: To determine the effect of 2 standard methods (i.e., twill tape versus adhesive tape) of securement on unplanned extubation, oral mucosa, and facial skin integrity of the orally intubated patient. DESIGN: A prospective, quasi-experimental design was used for the pilot study. SETTING: The setting for the pilot study included critical care units of 3 community hospitals and 1 veterans' hospital in a midwestern city. SUBJECTS: A total of 52 orally intubated adult subjects were enrolled in the study from the 4 clinical sites over a 6-month period of time. The participants in the study consisted of 30 men and 22 women. The subjects ranged in age from 22 to 85 years, with a mean age of 62.3 years. The mean length of intubation was 89.6 hours. OUTCOME MEASURES: The outcome measures of the study were (1) unplanned extubation, (2) oral mucosa status, and (3) facial skin integrity. INTERVENTIONS: Endotracheal tube securement with either the twill tape or the adhesive tape securement method. RESULTS: With use of multiple analysis of variances (MANOVA) and repeated analyses of variances (ANOVAs), there were no significant differences by time or type of endotracheal tube securement method on oral mucosa or facial skin integrity. A chi-square analysis demonstrated no significant association between the 2 types of endotracheal tube securement when comparing their efficacy in preventing unplanned extubation. CONCLUSION: The findings of this pilot study demonstrated both methods of endotracheal tube securement to be comparable in preventing unplanned extubation and in maintaining oral mucosa status and facial skin integrity.
