The '2-week rule' for suspected breast carcinoma: a qualitative study of the views of patients and professionals.

BACKGROUND: The '2-week rule' for the referral of patients with potential cancers is an important but controversial development. AIMS: To investigate the 2-week rule for women with breast problems from the perspective of the patients and of healthcare professionals. DESIGN OF STUDY: Qualitative study using semi-structured interviews. SETTING: Patients referred to two breast care units and professionals from primary and secondary care in Teesside and Hartlepool. METHOD: Semi-structured interviews with a purposive sample of 12 patients referred under the 2-week rule and 20 professionals. RESULTS: All women experienced considerable worries in the time leading up to diagnosis. This affected relationships with others, and they used selective telling to help maintain control over their own anxiety and prevent anxiety in others. They were not aware of the 2-week rule as a new initiative, but wanted quick referral to assure them that they did not have cancer. Patients felt they needed more information about breast symptoms and the referral process. Comments about communication with professionals, both good and poor, were frequent in their accounts, which contrasted with the absence of such concerns in the accounts of the professionals. The professionals thought that the 2-week rule was advantageous in reducing anxiety, but thought that disadvantages included longer waits for patients referred outside the rule and increased pressure on hospital services. Cultural changes, including increased patient assertiveness and 'breast awareness', were considered important contextual factors. General practitioners (GPs) were concerned about missing diagnoses in patients statistically unlikely to have carcinomas. CONCLUSION: Differences in emphasis were apparent, with patients wanting to be assured that they did not have cancer, specialists concerned both about increased workload and the impact on patients with cancers, and GPs anxious about missing diagnoses. The 2-week rule compromises professional autonomy, which partially accounts for the anger directed against it. There is a need for patients to have more information, and they place great value on good communication. All patient responders experienced significant distress while waiting to be seen.     

Gold: an old drug still working in refractory pemphigus

BACKGROUND: The mainstay of treatment for pemphigus is systemic corticosteroids. Different adjuvants have been used to reduce side-effects of long-term corticotherapy. Gold is an anti-inflammatory drug used in autoimmune diseases, whose use has waned with the advent of new immunosuppressive agents. OBJECTIVE: To study the outcome of the use of intramuscular gold treatment of pemphigus vulgaris refractory to previous therapies. METHODS: Thirteen patients with pemphigus vulgaris who had failed to respond to several prior therapies were treated with aurothiomalate, as a steroid-sparing agent. Patients were monitored to assess disease activity and gold toxicity. RESULTS: Seven patients achieved complete remission. Four patients were able to taper prednisone doses, although pemphigus flared when prednisone was discontinued or reduced. Toxicity was observed in the other two patients. CONCLUSIONS: In 53.4% of the patients, the use of chrysotherapy resulted in the complete clearing of the disease, discontinuation of all systemic therapies and induced a long-term clinical remission. Prednisone doses were able to be reduced in the remaining 46.6%. Any side-effects were reversible with drug discontinuation. Gold therapy showed efficacy as a secondary line treatment in refractory pemphigus vulgaris.     

Early changes in hemoglobin and hematocrit levels after packed red cell transfusion in patients with acute anemia

BACKGROUND: Equilibration of hemoglobin concentration after transfusion has been estimated to take about 24 hours, but some studies have shown that earlier measurements reflect steady-state values in persons who have not bled recently. This study was aimed at assessing the changes over time in hemoglobin concentration after transfusion in acutely anemic patients because of recent bleeding. STUDY DESIGN AND METHODS: Thirty-two normovolemic patients recovering from an acute bleeding episode who were no longer thought to be bleeding and who received a 2- unit red cell transfusion were studied. At baseline and 15, 30, 60, and 120 minutes and 24 hours after transfusion, hemoglobin concentration and hematocrit values were measured. RESULTS: The administration of 2 units of packed red cells elicited a 24-hour increase of 22.4 +/− 6.8 g per L in hemoglobin concentration. Hemoglobin values were not different at any of the defined posttransfusion times. Hematocrit levels experienced similar changes over time. Agreement between 15-minute and 24-hour values was excellent, as only 6 percent of patients exhibited a clinically significant difference (> 6 g/L) between the hemoglobin measurements. CONCLUSION: Hemoglobin and hematocrit values rapidly equilibrate after transfusion in normovolemic patients who are recovering from an acute bleeding episode. This fact would allow a rapid assessment of the effects of transfusion and of the recurrence of bleeding in patients remaining at risk.     

L-arginine reverses the antinatriuretic effect of cyclosporin in renal transplant patients

BACKGROUND: Cyclosporin has been shown to facilitate renal vasoconstriction and to have an antinatriuretic effect. The existence of an interference of cyclosporin with the vasodilating properties of endothelium mediated by nitric oxide production could mediate these effects. On the other hand, the infusion of the nitric oxide precursor L-arginine has been shown to induce renal vasodilatation and to facilitate natriuresis in normal volunteers. We have investigated the renal effects of the administration of an infusion of L-arginine in renal transplant patients chronically treated with cyclosporin. To facilitate the analysis of the data the effects of the administration of a similar dose of cyclosporin on renal function during the infusion of a vehicle were also investigated during the administration of a vehicle of L-arginine. DESIGN: Ten male renal transplant patients, chronically treated with cyclosporin and with a stable renal function were studied during 2 consecutive days after the administration of the usual morning dose of cyclosporin. The first day they received an intravenous infusion of vehicle and the second the infusion of graded doses of L-arginine (50, 100, 150 mg/kg/h) during 3 consecutive h. RESULTS: The first day, after cyclosporin administration a significant fall (P < 0.01) was observed in natriuresis and kaliuresis in the absence of changes in renal plasma flow and glomerular filtration rate. After the administration of L-arginine significant (P < 0.01) increases of renal plasma flow, glomerular filtration rate, and natriuresis were seen. The increase in blood levels of cyclosporin after its administration did not differ between days 1 and 2. CONCLUSION: These results indicate that L-arginine facilitates renal vasodilatation and natriuresis in renal transplant patients. Furthermore, the observed increase in sodium excretion could indicate that L-arginine counteracts the antinatriuretic effect of cyclosporin.
