Frequency, nature and determinants of pharmaceutical consultations provided in private by Dutch community pharmacists

OBJECTIVE: According to a report published by the federation of Dutch patients' associations, patients would like to see a pharmacist, who acts more as a personal adviser. This raised the question, how often Dutch community pharmacists have personal consultations with their patients in daily practice, on which factors this depends, and what kind of topics are discussed during these meetings. SETTING: Community pharmacies in the Netherlands. METHOD: A questionnaire was distributed among 800 randomly selected pharmacies. Questions were restricted to consultations characterized by one-to-one contact, drug therapy related content, and adequate privacy. These consultations were labelled as pharmaceutical consultations in private to distinguish them from other contacts between pharmacists and patients. MAIN OUTCOME MEASURE: Number, content, and character of consultations. RESULTS: 198 (24.8%) community pharmacies responded. The pharmacists provide an average of roughly 1.2 consultations in private per working day. The vast majority of respondents provided face-to-face and telephone consultations (94.4 and 91.9%, respectively), only a minority gave consultations by e-mail (30.8%). These consultations primarily dealt with topics related to medication safety. The mean overall time spent was 290 min per month. A relatively high frequency of personal consultations was significantly associated with the absolute number of full-time equivalent pharmacists in the pharmacy. CONCLUSION: The frequency of pharmaceutical consultations in private is low, but may be improved by reorganisation of the pharmacist's activities. The possibility of personal consultations by e-mail is not yet well-developed. Further research is needed to assess the patient's view of pharmaceutical consultations in private.     

Glycolytic enzymes in breast cancer, benign breast disease and normal breast tissue

The activities of hexokinase, phosphofructokinase, aldolase, enolase and pyruvate kinase were studied in breast cancer tissues, in comparison to benign breast disease and normal breast tissues. The enzyme activities in breast cancer were significantly increased compared to normal and benign breast tissues (p less than 0.001). Also the increase in activity in benign disease compared to normal was statistically significant (p less than 0.001). Within the group of benign diseases, fibroadenomas could be distinguished from fibrocystic disease, the former generally showing higher activities compared to the latter (p less than or equal to 0.05). Carcinoma subgroups, classified according to their histology, could not be recognized enzymologically. In addition, isozyme composition of pyruvate kinase and enolase was studied. We did not find a significant shift towards K type pyruvate kinase expression in benign disease compared to normal breast tissues. Also fibroadenomas did not differ from fibrocystic disease. However, the amount of K type pyruvate kinase in carcinomas proved to be significantly higher in comparison to benign disease and normal breast tissues (p less than 0.001). Expression of alpha gamma-enolase in normal breast tissue was virtually absent. In benign disease only a minority of specimens did show the hybrid alpha gamma-enolase. Nearly all carcinomas had alpha gamma-enolase expression and in 20% of the carcinomas gamma gamma-enolase could be detected (so-called neuron-specific enolase). By discriminant analysis, the function giving the best discrimination compared to the histological data was based on natural logarithm aldolase and the total of gamma-enolase subunits. Contrary to expectation, the regulator enzymes of glycolysis; i.e., hexokinase, phosphofructokinase and pyruvate kinase were not included in this discriminant function. The best fit produced a 90% correct classification in both benign and malignant disease. If these findings are confirmed to a larger series, the discrimination is sufficiently strong to form the basis of a clinically useful tool.

Magnesium carbonate is an effective phosphate binder for chronic hemodialysis patients: a pilot study.

OBJECTIVE: This study was designed to evaluate the efficacy of magnesium carbonate as a phosphate binder in hemodialysis patients. DESIGN: This study was a prospective, randomized, open-label trial comparing magnesium carbonate/calcium carbonate versus calcium acetate as a sole phosphate binder. SETTING: This study involved outpatient hemodialysis. PARTICIPANTS: We recruited 30 stable hemodialysis patients without a history of frequent diarrhea. INTERVENTION: After receiving informed consent, we randomized patients 2:1 to magnesium carbonate versus calcium acetate. The dose of each binder was titrated to achieve the Kidney Disease Outcomes Quality Initiative (K/DOQI) phosphate target of <5.5 mg/dL. MAIN OUTCOME MEASURE: The efficacy-phase serum phosphorus concentration and the percentage of patients meeting K-DOQI targets for phosphorus, along with the daily elemental calcium intake, were the primary outcome measures. RESULTS: Magnesium carbonate provided equal control of serum phosphorus (70.6% of the magnebind group and 62.5% of the calcium acetate group had their average serum phosphorus within the K-DOQI target during the efficacy phase), while significantly reducing daily elemental calcium ingestion from phosphate binders (908 +/- 24 vs. 1743 +/- 37 mg/day, P < .0001). CONCLUSION: Magnesium carbonate was generally well-tolerated in this selected patient population, and was effective in controlling serum phosphorus while reducing elemental calcium ingestion.     

An open-label efficacy pilot study with pimecrolimus cream 1% in adults with facial seborrhoeic dermatitis infected with HIV

BACKGROUND: Seborrhoeic dermatitis (SD) is a common dermatosis in human immunodeficiency virus (HIV)-positive patients, many of whom do not respond satisfactorily to conventional topical treatments such as corticosteroids and antifungals. OBJECTIVE: A pilot study to investigate the efficacy and tolerability of pimecrolimus cream 1% in HIV-positive patients with facial SD. METHODS: In a single-centre study, 21 HIV-infected patients with mild to severe SD were treated twice daily with pimecrolimus cream 1% for 14 days. Thereafter, treatment was discontinued and patients followed up for 5 weeks. Skin involvement at baseline and on days 7, 14, 21, 35 and 49 was assessed using a four-point clinical score and digital photography. MAIN OUTCOME MEASURES: Efficacy and safety of pimecrolimus cream 1% treatment and incidence of relapse in the follow-up phase. Results Marked improvement was seen in clinical parameters at day 7, with >or= 90% patients clear of symptoms at day 14. Relapse was observed at day 35 but signs were milder than at baseline. All patients responded to therapy, despite their immunological status. Pimecrolimus did not alter CD4(+) and CD8(+) T-cell counts or viral load during the treatment period. CONCLUSION: Pimecrolimus cream represents a new, effective therapeutic option for facial SD in HIV patients.     

Acute arteriolar vasoconstriction following furosemide in conscious spontaneously hypertensive rats

In a previous study in conscious spontaneously hypertensive rats (SHR), we observed an immediate decrease in the cardiac index (CI) and an increase in the total peripheral resistance index (TPRI) following the administration of furosemide. The present study was designed to evaluate the regional hemodynamic effects and the involvement of sinoaortic baroreceptors in the increase in TPRI. In SHR instrumented for the measurement of central hemodynamics, 8 mg.kg-1 furosemide decreased CI from 31.0 +/- 2.5 ml.min-1.100 g bw-1 by 9.5 +/- 1.3 ml.min-1.100 g bw-1 (n = 7). TPRI increased maximally from 5.7 +/- 0.8 by 2.7 +/- 0.5 mm Hg.min.100 g bw.ml-1. The effect on TPRI was not affected by sinoaortic denervation (SAD) to abolish arterial baroreflexes. However, furosemide induced a significantly greater decrease in CI (-12.6 +/- 1.2 ml.min-1.100 g bw-1; n = 7) after SAD. Furosemide effectively reduced the mean arterial pressure in SAD SHR (-21 +/- 9 mm Hg) but not in sham-denervated SHR. Furosemide (8 mg.kg-1) reduced renal, mesenteric and hindquarter blood flow to a comparable extent (approximately 20%) in intact SHR. The reduction in renal flow at 3.5 min after injection (-17.9 +/- 4.1%; n = 8) was significantly greater than the reduction in mesenteric (-7.1 +/- 4.7%) and hindquarter blood flow (-4.2 +/- 3.7%), suggesting that the renal bed responds faster. Thereafter, the flow reductions in the three beds were not different. The results show that furosemide causes a general vasoconstriction in conscious SHR.(ABSTRACT TRUNCATED AT 250 WORDS)
