Adherence issues in children and adolescents receiving highly active antiretroviral therapy.

The introduction of highly active antiretroviral therapies (HAART) for the treatment of paediatric HIV infection poses additional adherence challenges for children and families living with HIV A preliminary survey of 18 parents of children receiving HAART in Australia showed that although parents report high level of child adherence to HAART, specific features of the medication regimen, such as taste and number of medications made administration of HAART extremely difficult.Moreover, interaction between the treatment regimen and the day-to-day lives of families increases the adherence challenge. While some agreement exists in relation to the concerns families have about negative aspects of HAART; the diversity of issues suggests the need for ongoing and individualized support and information to families.

A quality assurance review of outpatient care of children with life-threatening asthma exacerbations.

OBJECTIVES: A hospital admission for asthma represents an opportunity to address and improve asthma control. The aims of this study were to compare the ambulatory care of children admitted to the intensive care unit (ICU) following a life-threatening asthma exacerbation with published guidelines of asthma management and to identify areas that could be targeted for change. METHODS: A retrospective review of case notes of children admitted to the ICU with asthma over a 6-month period. Variables recorded were: demographic; asthma history (including prior pattern of asthma, hospital admissions, interval treatment and managing doctor); admission details (consultation of respiratory team and asthma educator); and discharge management. RESULTS: There were 40 admissions of 38 children (24 males) with mean age 5.7 years (range 1.1-14 years). The majority (58%) had previous admissions for asthma (55 admissions in 22 children), with 23% of these to ICU. Sixty three per cent of those with previous admissions had persistent asthma, but only 29% were on inhaled corticosteroid (ICS). Most (60%) were managed by their local medical officer (LMO). Use of ICS was more likely if managed by a paediatrician. A respiratory subspecialist was consulted in 42% and the asthma educator in 70% of ICU admissions. Discharge medication included ICS in 74%, with no interval treatment in 18% of admissions. Follow up was by a respiratory subspecialist in 25% of cases. CONCLUSION: Asthma management before and after admission with life-threatening asthma did not conform to available guidelines. Persistent asthma was under-treated. Paediatricians were more likely to use interval treatment than LMO. We identified areas in which quality of care and outcome could be improved in this vulnerable group of asthmatics.

Prolonged peripheral parenteral nutrition with an ultrafine cannula and low-osmolality feed.

Peripheral parenteral nutrition is an attractive alternative to centrally delivered parenteral nutrition because it obviates the need for central venous cannulation and its attendant complications. Some 45 consecutive patients were fed peripherally using a 22-G polyurethane catheter and a fat-based, low-osmolality feed. Of these patients, 36 were fed for a median of 8.5 (range 3-31) days without peripheral vein thrombophlebitis (PVT). Seven patients developed PVT after a median of 6 (range 5-7) days. The cumulative daily risk of PVT was 0.016 episodes per day. These results suggest that prolonged (more than 7 days) problem-free peripheral parenteral nutrition is possible.

Long-term glucose homeostasis in patients on home parenteral nutrition.

Glycated haemoglobin (Hb A1c) was used as a marker of long-term hyperglycaemia in patients receiving high glucose loads for home parenteral nutrition (HPN). Thirty-six patients received a median weekly glucose delivery of 2000 g (800-4200) at a median infusion rate of 11.8 mg/kg/min (5.0-19.2). There was no correlation between Hb A1c (median- 3.1%, range 2.0-6.3%) and glucose infusion rate or weekly glucose load. It is concluded that significant prolonged hyperglycaemia does not appear to be a problem in patients on HPN managed by this unit.

Service providers' perceptions of substance use self-help groups.

Using a two-stage Delphi procedure, an investigation was carried out into health and welfare professionals' knowledge of and relationship with self-help groups (SHGs). Professionals indicated that they perceived SHGs to be generally helpful for persons with substance use problems. Provision of social support was the most commonly perceived helpful aspect of SHGs, and unsuitability for some clients was the most commonly perceived unhelpful-aspect. Persons motivated to address their problems were those perceived to be most likely to find a SHG useful, with those not so motivated, or who deny their problem, being perceived to be least likely to find a SHG useful. Drug and alcohol user treatment specialists reported greater perceived failure of SHGs to address underlying psychopathology and greater perceived benefit for clients lacking social support. This may be of particular relevance for future attempts to investigate the process of recovery in SHGs.

The incidence and management of catheter occlusion in patients on home parenteral nutrition.

For patients on Home parenteral nutrition (HPN), catheter-related problems are the major source of morbidity and occlusion of the central venous catheter is one of these. We have managed 17 episodes of catheter occlusion in 10 patients on HPN. The median time from insertion to occlusive episode was 23 months. 10 catheters (59%) were saved by the used of thrombolytics (one by thrombolytics and ethanol) and 7 were replaced. The recent incidence of catheter occlusion in this cohort was one episode per 150 patient-months of HPN (0.08 episodes per year). Patients with Crohns disease appear to be at greater risk of developing catheter occlusion (p = <0.05).

Pseudomonas infection of the catheter exit site successfully managed with topical acetic acid.

A case of recurrent catheter exit site infection with Pseudomonas aeruginosa is presented in a patient receiving home parenteral nutrition. The past episodes were managed by elective catheter replacement following extrusion of the catheter cuff. We describe the successful use of acetic acid to the exit site which resulted in the eradication of the organism and complete resolution of all signs.

Youth health: street kids in an inner suburb of Melbourne.

This study has investigated a primary medical care service established within a Community Health Centre aimed at young homeless people. The study shows the service clearly reaches the target group, and indicates other young people are also prepared to access this service. The results illustrate to some extent the collective disadvantages faced by this group of young people, not only because of their homelessness, but in terms of their needs regarding personal and financial support. In particular, the study confirms substance abuse as a major problem in this population, and indicates the need for further examination of the use of health care services by this group, particularly in relation to women's health issues.

Essential fatty acid status in patients on long-term home parenteral nutrition.

BACKGROUND: Patients on total parenteral nutrition are known to be at risk of the development of essential fatty acid deficiency, presenting as a syndrome with scaly skin lesions and characterized by low plasma and erythrocyte linoleic acid concentrations. The essential fatty acid status of patients on long-term home parenteral nutrition who do have access to oral feeds has not been studied. METHODS: With the use of an isocratic high-performance liquid chromatography method, fatty acids were measured in the erythrocytes and plasma of 25 nonfasting patients on long-term home parenteral nutrition and the findings compared with those of 46 hospital outpatients not on nutrition support and five laboratory staff. RESULTS: Statistically significant differences in the two groups were limited to the erythrocytes. Linoleic acid was significantly lower (25.2 vs 40.7 mumol/10(6) red blood cells, p < .0001) and showed a significant correlation with triceps skinfold thickness (r = .52, p = .013). Palmitoleic and oleic acids were higher in patients than controls (10.8 vs 8.4 mumol/10(6) red blood cells, p = .009; 61.2 vs 51.7 mumol/10(6) red blood cells, p = .003). CONCLUSIONS: Despite IV linoleic acid administration, patients on long-term home parenteral nutrition have low erythrocyte stores of this essential fatty acid. This appears to be related to their low body fat stores. We suggest that they may be using much of the infused linoleic acid as an energy source and therefore are at risk of subclinical essential fatty acid deficiency.
