RESUMEN
Central venous access port devices (CVAPD) are necessary for delivery of prolonged infusional chemotherapy or in patients with poor peripheral venous access. Previous studies of Hickman catheters report complication rates in about 45% of patients. Our aim was to assess the early and late complication rate, and duration that the CVAPD remained functional, following insertion by interventional radiologists in patients with solid tumours. A prospective study was undertaken in 110 consecutive patients who had insertion of 111 subclavian CVAPD. The median age of patients was 57 years (range 17-83), 64 were females; 68 patients (61%) had gastrointestinal tumours and 25 (23%) had breast cancer. CVAPD were successfully implanted in all but one patient. There were four (4%) immediate major complications: thrombosis 2 and pneumothorax 2. Nine patients (8%) had bruising or pain. Four devices (4%) became infected. In total, 100 CVAPD (90%) were either removed as planned at the end of treatment (n=23) after a median 203 days, or remained in situ for a median of 237 days (7-1133). Premature removal occurred in eight patients due to infection (n=4), thrombosis (n=3) or faulty device (n=1). Four patients were lost to follow-up. Radiological insertion of CVAPD is safe and convenient with low rates of complications.

The hyperglycemia, hyperinsulinemia, insulin resistance, and obesity syndrome associated with type 2 diabetes can have debilitating consequences. The biguanide metformin has a mechanism of action that is complementary to those of insulin and the sulfonylureas, suggesting that combination therapy that includes metformin may result in improved glycemic control. The purpose of this retrospective chart review was to determine the effects of adding metformin in an uncontrolled fashion to existing therapy in obese patients with type 2 diabetes who had suboptimal glycemic control and insulin resistance. For the review, the records of 124 patients were divided into two groups: group 1 included 71 patients who were taking insulin with or without a sulfonylurea, and group 2 consisted of 53 patients who were taking a sulfonylurea alone. Metformin was added to patients' existing therapy in conjunction with downward titration of the sulfonylurea and insulin doses. A retrospective chart review was conducted at the end of 6 months for group 1 and at the end of 12 months for group 2 to determine the change from baseline in measures of diabetes control (ie, insulin and sulfonylurea dose, glycated hemoglobin [Hb A1c] value, body mass index [BMI], and lipid profiles). In group 1, the mean insulin dose decreased from 46.4 U/d at baseline to 6.1 U/d at the end of follow-up. Eighty-three percent of the patients were able to discontinue insulin therapy completely. Similarly, group 2 had statistically significant reductions in mean sulfonylurea dose. Both groups also achieved statistically significant reductions in Hb A1c, BMI, and total cholesterol level. The addition of metformin to treatment with insulin or sulfonylureas, either alone or in combination, significantly improved glycemic control and cholesterol levels and promoted weight loss in obese type 2 diabetic patients with insulin resistance. Less than 5% of patients reported mild, transient gastrointestinal side effects, none of which required cessation of metformin therapy. Five patients discontinued metformin due to lack of efficacy.

This paper will present the preliminary findings of a national Royal College of Speech and Language Therapists audit of speech and language therapy and health visiting services to the pre-school population. The audit was carried out in six districts of the United Kingdom, representing a broad range of locations and models of service delivery. The purpose of the audit was to evaluate specific aspects of the management of children with speech and language difficulties. Audit tools were applied to referral and selection procedures, inservice training and parent programmes. Preliminary findings and their implications are discussed.

This paper looks at a controlled study which aimed to measure the efficacy of a parent programme. The parents involved were all parents of pre-school children with specific expressive language delay (SELD). A number of measures were used to identify changes in mother-child interaction and language development. Significant differences were noted in the experimental group while the control group remained stable over time. The results indicate the potential effectiveness of this type of intervention for children identified as having SELD.

This paper presents the problems associated with the implementation of a new model of service delivery involving parent programmes. Factors affecting the cost-effectiveness included the influence of the learning curve. Change, innovation and adoption will be discussed in relation to the new model of service delivery. The correlation with years of experience will also be considered.
