Utilization and clinical manifestations of human immunodeficiency virus type 1-infected children presenting to a pediatric emergency department

A retrospective review was conducted of 22 human immunodeficiency virus type 1 (HIV-1)-infected children under 13 years of age presenting to an inner city pediatric emergency department to determine their clinical manifestations of disease and utilization of emergency department services. When compared with a population of 78 normal children, the infected children were more likely to present with cough, difficulty in breathing, and lethargy. Pneumonia, diarrhea, and dehydration were more common diagnoses in the infected children, who were more likely to be admitted, had more invasive procedures, and required more professional staff to provide care. There was no significant difference in the frequency of visits (visits/month of age) when comparing the two groups. As expected, the infected children presented with problems associated with pediatric HIV-1 infection. Our results suggest that HIV-1-infected children require an increased level of care in the emergency department and subsequent admission to the hospital. These children did not visit the emergency department more frequently than the controls. This may be the result of an active outpatient HIV clinic in our hospital, which is available to both scheduled and unscheduled patients.     

Narrative and procedural discourse in temporal lobe epilepsy.

It is well established that some individuals with temporal lobe epilepsy (TLE) demonstrate language deficits at the single word level. However, discourse production rarely has been examined quantitatively within this group. This study compared adult TLE patients with an early seizure onset (< or = age 14 years, n = 27) to a control group (n = 28) on narrative and procedural discourse tasks. As a group, the TLE patients performed normally on the procedural discourse task, but differed significantly from the controls on several narrative discourse variables. At the individual level, 30% of the TLE patients versus 4% of the controls demonstrated impaired discourse ability (p and 0.01). Within this early onset TLE group, discourse performance was not associated with demographic or seizure history variables. Considering the cognitive domain, discourse performance correlated significantly with working memory. In summary, mild discourse dysfunction was present in a significant minority of early onset TLE patients, but this deficit was not closely associated with other language measures. Discourse ability and its neuropsychological, neuroanatomical and conversational speech correlates deserve further study in TLE patients.     

Comparison of three oral sip-feed supplements in patients with cancer

This study set out to compare the long-term palatability of three oral sip-feed supplements. Sixty patients with various malignancies were randomized to receive one of three products—Build-Up, Fortimel and Fortisip. Participants were encouraged to take as much of the supplements each day for as long as they could manage. At the initial tasting, palatability and acceptability of the products was recorded and this was repeated throughout the trial period. Patients' reasons for discontinuing the trial were noted.
Build-Up was found to be the best-tolerated product of the three. It was taken for a significantly longer time than either Fortimel or Fortisip. There was an indication that Build-Up was more acceptable at the initial tasting than Fortisip but not Fortimel. A smaller proportion of patients stopped taking Build-Up due to flavour-related reasons compared to Fortisip but there was no significant difference between Build-Up and Fortimel. In all, 54% of the patients discontinued the trial for flavour-related reasons. Thirty-five per cent found that the sip-feeds they had been allotted unpalatable at the initial tasting, while 19% stopped the trial due to 'flavour fatigue'. Only 10% of the sample continued taking their allotted product for 90 days or more.     

Developing nurse practitioners to develop practice: the experiences of nurses working on a Nursing Development Unit

Aim To elicit nurses' accounts of their involvement with nursing research and their interpretations of the meaning of these projects for their practice.
Background The links between research and practice development in health care are poorly understood and require further exploration in the light of the emerging research and development agenda within the National Health Service.
Methods Semi-structured interviews were conducted with 15 qualified nurses working on a Nursing Development Unit. The interviews were tape recorded, transcribed and analysed thematically.
Findings Data analysis identified two distinct groups—a core group of nurses actively engaged in the research projects and a peripheral group involved in data collection. The characteristics of the core group mirror the characteristics of those involved in non-research-based practice development activities.
Conclusions Engaging in research activities does not always result in the development of practice, however, there appears to be a link between practice development and critical thinking.     

The inhibition of the oxidation of low density lipoprotein by (+)-catechin, a naturally occurring flavonoid.

(+)-Catechin inhibited the copper-catalysed oxidation of human low density lipoprotein (LDL) in a dose-dependent manner with complete inhibition at 20 micrograms/mL. The flavonoid at a concentration of 50 micrograms/mL also inhibited oxidation of LDL induced by the mouse transformed macrophage J774, human monocyte-derived macrophages and vascular endothelial cells isolated from human umbilical cords. LDL modified by copper-catalysed or cell-induced oxidation was endocytosed and degraded by human macrophages at a much greater rate than native LDL. LDL reisolated from copper or cell incubations in the presence of (+)-catechin was endocytosed and degraded at rates similar to native LDL. (+)-Catechin appeared to inhibit the uptake and degradation by macrophages of cell-modified LDL. The actions of (+)-catechin on cell-induced oxidation of LDL are consistent with the ability of flavonoids of similar structure to inhibit lipoxygenases and with a role for lipoxygenases in cell-induced modification of LDL in vivo.     

Acute management of intracranial hemorrhage in patients receiving thrombolytic therapy: case reports

Intracranial hemorrhage is an uncommon complication of antithrombotic therapy. We present two patients who suffered life-threatening intracranial bleeding as a complication of thrombolytic/anticoagulant treatment. Early diagnosis and treatment appear to be crucial factors for survival. We suggest an approach to perioperative management for intracranial hemorrhage resulting from antithrombotic therapy.
