Impact on blood pressure control of a six-month intervention project

The aim of this study is to evaluate the impact of a six-month structured education programme on blood pressure (BP) control in patients with uncontrolled hypertension. All patients attending the Specialist Hypertension Clinic, University Hospital of the West Indies (UHWI), between January 4 and March 29, 1999, with blood pressure > 140/90 mmHg (n = 80), were randomly divided into Group 1, cases (n = 42) and Group 2, controls (n = 38). A 40-item pretested questionnaire, administered at the baseline and final visits of both groups, elicited demographic, lifestyle and knowledge data. Group 1 attended monthly structured interventions for six months. Except for diastolic blood pressure among male controls, diastolic blood pressure and systolic blood pressure were significantly reduced at the end of the intervention period (p < 0.01). Knowledge improved among the male patients (p < 0.01). Among the female patients, activity scores were significantly increased (p < 0.01), weight (p < 0.05) and BMI (p < 0.05) were significantly reduced. There were no differences in these variables among the controls. This intervention had a benefit in blood pressure control.     

Pharmaceutical expenditure in Spain: cost and control.

In recent years, the Spanish government has been battling to keep pharmaceutical expenditures under control. Its measures include control of prices, introduction of a "negative list" of drugs no longer reimbursed, increased cost-sharing, and introduction of overall budgets for pharmaceutical expenditures. Although the average prices of old pharmaceutical products declined by 39 percent over the last 15 years and consumption in value increased by only 10 percent, real pharmaceutical expenditures in Spain increased by 264 percent over that period. The main reason for the continuing rise in these expenditures and the failure of cost-containment measures is the introduction of new, more expensive drugs, which often fail to offer any real therapeutic advantages over products already on the market. This situation is exacerbated by a lack of effective demand-side measures such as budgets for doctors and lack of a generics market.     

Mammary tuberculosis: percutaneous treatment of a mammary tuberculous abscess

It is currently very rare to find mammary involvement in cases of tuberculosis, in either primary or secondary form. Diagnosis is classically clinical and microbiological, and the basic techniques used in imaging diagnosis are mammography and ultrasound. Computed tomography may define the involvement of the thoracic wall in those cases which present as mammary masses adhering to deep levels, and is also able to evaluate accompanying pulmonary disease, if it is present. Traditionally, treatment has consisted of quadrantectomy and specific antibiotic therapy. We present a case of tuberculous mammary abscess secondary to pulmonary disease, which was treated by percutaneous drainage controlled by CT and specific antibiotic therapy. We revise the diagnosis, differential diagnosis and treatment of mammary tuberculosis. Received: 27 July 1998; Revision received: 2 February 1999; Accepted: 20 April 1999     

Comparison of remifentanil versus regional anaesthesia in children anaesthetised with isoflurane/nitrous oxide. International Remifentanil Paediatric Anaesthesia Study group

We compared the efficacy and safety of a remifentanil (0.25 microg x kg(-1) x min(-1)-based balanced anaesthetic technique with a bupivacaine-based regional anaesthetic technique in an open label, multicentre study in 271 ASA physical status 1 or 2 children aged 1-12 years. Subjects requiring major intra-abdominal, urological or orthopaedic surgery were randomly allocated to receive either intravenous remifentanil (group R; n = 185) or epidural bupivacaine (group B; n = 86) with isoflurane/nitrous oxide for their anaesthesia. The majority of children in both groups (85% in group R, 78% in group B) showed no defined response to skin incision, and although the mean increase in systolic blood pressure (+11 mm Hg) was significantly greater in group R than in group B, this change did not represent a serious haemodynamic disturbance. More children in group R (31%) required interventions to treat hypotension and/or bradycardia than those in group B (12%), but these were easily managed by administration of fluids or anticholinergic drugs. Adverse events, mainly nausea and/or vomiting, occurred in 45% of group R and 42% of group B (NS). The adverse event profile of remifentanil in this study was typical of a potent mu-opioid receptor agonist. Remifentanil was as effective as epidural or caudal block in providing analgesia and suppressing physiological responses to surgical stimuli in children aged between 1 and 12 years undergoing major abdominal, urological, or orthopaedic surgery under isoflurane/nitrous oxide anaesthesia.     

Clinical significance of abdominal scintigraphy using 99mTc-HMPAO-labelled leucocytes in patients with seronegative spondyloarthropathies

Abdominal scintigraphy shows silent gut inflammation in patients with spondyloarthropathies (Sp) without clinical evidence of gut inflammation. Abdominal scintigraphy images are different than those obtained in patients with ulcerative colitis or Crohn's disease and are not related to the anti-inflammatory drugs administered. The aim of this study was to examine the clinical associations of findings on abdominal scintigraphy in patients with Sp. A total of 204 Sp patients (European Spondylarthropathy Study Group 1991 criteria) and 54 non-Sp controls receiving non-steroidal anti-inflammatory drugs were studied. Abdominal scintigraphy images were obtained at 30 and 120 min after injection of technetium-99m hexamethylpropylene amine oxime (^99mTc-HMPAO)-labelled leucocytes. ^99mTc-HMPAO-labelled leucocyte scans were positive in 104 Sp patients (50.9%) and in six non-Sp controls (2.9%) (P<0.001; OR=8.32; 95% CI=3.23-22.67). Silent gut inflammation was not associated with any of the following: age of onset, duration of evolution, sex, family history of Sp or psoriasis, articular manifestations, extra-articular manifestations, radiological findings or HLA-B27 positivity. Positive abdominal scintigraphy was associated with active disease (P<0.0001; OR=52.7; 95% CI=19-145.6) and an increase in the C-reactive protein (P<0.005; OR=3.4; 95% CI=1.5-7.4). It is concluded that (a) abdominal scintigraphy using ^99mTc-HMPAO-labelled leucocytes is of value in detecting the silent gut inflammation in Sp patients, and (b) silent gut inflammation is related to the clinical activity, but is not associated with any particular type of illness or with HLA-B27.     

Rosuvastatin: a high-potency HMG-CoA reductase inhibitor.

OBJECTIVE: To summarize the relevant pharmacologic, clinical, and safety data regarding rosuvastatin (Crestor--AstraZeneca), the most recently marketed 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor approved for the treatment of dyslipidemia. DATA SOURCES: Medline search from years 1990 thru 2005 using the keywords HMG-CoA reductase inhibitor, hypercholesterolemia, lipid-lowering agents, rosuvastatin, and statins. Study Selection: Review articles, clinical trials, case reports, abstracts, and data on file from the manufacturer concerning rosuvastatin and other statins were considered for inclusion. DATA EXTRACTION: English-language studies were selected for inclusion. DATA SYNTHESIS: Multiple clinical trials have revealed that use of rosuvastatin is associated with greater reductions in low-density lipoprotein cholesterol (LDL-C) across the dose range of 5-40 mg/day than any other currently available statins. Rosuvastatin also significantly increases high-density lipoprotein cholesterol and reduces triglycerides significantly as well. In clinical trials, rosuvastatin was well tolerated, with a low incidence of adverse events and a safety profile similar to that of the other marketed statins. At present, no large-scale primary or secondary prevention clinical trials document either long-term safety of rosuvastatin or its effectiveness in preventing coronary events. CONCLUSION: Compared with other statins, rosuvastatin offers the greatest lipid-lowering efficacy at the lowest dose in treating patients with dyslipidemia and with a similar safety profile over the short-term. Rosuvastatin may allow more patients to achieve their LDL-C goals than any other statin and at a lower dose than other agents.     

Epirubicin, cisplatin and docetaxel combination therapy for metastatic gastric cancer.

BACKGROUND: Docetaxel is a new agent with activity in metastatic gastric cancer. This phase II study was designed to evaluate the activity and safety of an epirubicin, cisplatin and docetaxel combination in patients with this disease. PATIENTS AND METHODS: Forty-six patients with gastric adenocarcinoma with measurable distant metastasis were eligible for the study. Patients received epirubicin 50 mg/m(2) and docetaxel 60 mg/m(2), on day 1, and cisplatin 60 mg/m(2) on day 2. Granulocyte colony-stimulating factor 300 mug/day subcutaneously was given on days 5 and 6. Cycles were repeated every 3 weeks for a maximum of eight courses. RESULTS: All patients were evaluable for response and toxicity. Two complete and 21 partial responses were observed, with an overall response rate of 50% [95% confidence interval (CI) 36% to 64%]. Stable disease was observed in 13 patients (28%) and progressive disease in 10 patients (22%). The median time to progression was 6 months (95% CI 5-7) and the median overall survival was 11.2 months (95% CI 8.5-13.9). Grade 3/4 neutropenia, thrombocytopenia and anemia occurred in 46%, 7% and 13% of patients, respectively. There were five episodes of febrile neutropenia in four patients. Other grade 3 toxicities included mucositis in three patients (6.5%), vomiting in four patients (8.7%) and diarrhea in one patient (2%). There were no cardiac toxicity, severe neurotoxicity or treatment-related deaths. CONCLUSIONS: The epirubicin, cisplatin and docetaxel combination is an active and well tolerated novel chemotherapy regimen for treating metastatic gastric cancer and deserves further evaluation in randomized studies.     

Gender-specific gene expression in post-mortem human brain: localization to sex chromosomes.

Gender differences in brain development and in the prevalence of neuropsychiatric disorders such as depression have been reported. Gender differences in human brain might be related to patterns of gene expression. Microarray technology is one useful method for investigation of gene expression in brain. We investigated gene expression, cell types, and regional expression patterns of differentially expressed sex chromosome genes in brain. We profiled gene expression in male and female dorsolateral prefrontal cortex, anterior cingulate cortex, and cerebellum using the Affymetrix oligonucleotide microarray platform. Differentially expressed genes between males and females on the Y chromosome (DBY, SMCY, UTY, RPS4Y, and USP9Y) and X chromosome (XIST) were confirmed using real-time PCR measurements. In situ hybridization confirmed the differential expression of gender-specific genes and neuronal expression of XIST, RPS4Y, SMCY, and UTY in three brain regions examined. The XIST gene, which silences gene expression on regions of the X chromosome, is expressed in a subset of neurons. Since a subset of neurons express gender-specific genes, neural subpopulations may exhibit a subtle sexual dimorphism at the level of differences in gene regulation and function. The distinctive pattern of neuronal expression of XIST, RPS4Y, SMCY, and UTY and other sex chromosome genes in neuronal subpopulations may possibly contribute to gender differences in prevalence noted for some neuropsychiatric disorders. Studies of the protein expression of these sex-chromosome-linked genes in brain tissue are required to address the functional consequences of the observed gene expression differences.
