Reasons related to adherence in community-based field studies.

This study identified participants' reasons for good, marginal or poor adherence, or withdrawing from community-based clinical studies using a dietary and/or drug intervention. Adults aged 48-75 years participated in one of three studies related to decreasing colon polyp recurrence. Qualitative data from progress notes (N = 675) and end-of-study evaluations (N = 87) were coded using constant comparative analysis with 100% content validity panel agreement. Most common reasons for non-adherence were barriers such as side-effects, interference with vacation plans, unrelated illness, forgetting and competing outside stressors. Participation motivators were benefits such as altruism, medical benefits, free service and staff rapport. Findings supported the Health Behavior in Cancer Prevention model-based approach to adherence interventions and provided directions for adherence promotion in future community-based clinical studies.

[The regression behavior of choroid melanoma following radiotherapy--a new prognostic parameter?].

The present paper reports on follow-up examinations of 246 patients after Ruthenium106 treatment of choroidal melanomas (follow-up time 1.8 to 13 years). In January 1988, 212 patients were alive and free of metastases; 15 had died, 12 of them of melanoma metastases, and 17 could not be followed up. In a retrospective analysis of factors influencing tumor-related mortality, the rate of regression of irradiated tumors was found to be particularly significant. The mean time taken to reduce tumor volume by half was 4.4 months in patients who died of metastases, as against 6.6 months in a matched group of survivors. Using discriminance analysis, the difference was found to be highly significant (P = 0.0058). In the total patient population, a significant correlation was found between pretreatment tumor volume and the probability of metastases (P = 0.058). It may be concluded, though with the qualification that the number of tumor-related deaths was small, that the tumor regression rate is an important factor in the prognosis for patients with Ruthenium-treated malignant choroidal melanomas.

[Urologic examination and treatment of patients with acute injuries of the spinal medulla].

During a period of one year, nine patients with traumatic lesions of the spinal medulla were examined and treated urologically. The patients were followed-up for 24-36 months and follow-up will continue. All of the patients were treated primarily with sterile intermittent catheterization by the nursing staff. Exceptions from this were patients in whom indwelling catheters were necessary on account of complicating conditions. During the acute phase, the patients were examined by a urologist and bladder function investigations with cystometry + electromyographic registration from the pelvic floor were undertaken. When patients had recovered from the spinal shock phase, emptying of the bladder supplemented by alpha-adrenergic blocking preparations and clean intermittent catheterization were instituted in the patients with supra-sacral lesions. Patients with infra-sacral bladder paresis were trained in miction on abdominal pressure supplemented by clean intermittent catheterization. No complications from this treatment have occurred and renal function has remained stable. Only one patient has an indwelling catheter and it has not proved possible to persuade the patient to accept removal.

Antifibrinolytic therapy in patients with aneurysmal subarachnoid haemorrhage.

In a prospective consecutive non-randomised study including 1076 patients with ruptured intracranial aneurysms 205 patients received epsilon aminocraproic acid (EACA) and 871 did not. No significant differences between the two groups concerning clinical condition on admission, sex, age, localisation and size of the aneurysms were seen. No cases of rebleeding (RB) were observed within the first 4 days in the EACA treated patients, but within the first 48 hours, which is the optimal period recommended for operation of patients in good clinical condition, this difference of the rates of RB between EACA treated and not treated patients is not significant. A significantly lower rate of RB was observed in the EACA group within the first 2 weeks, but no significant differences in morbidity and mortality were found at the 2-year follow-up examination.
