Beta-blockers for the treatment of problematic hemangiomas

OBJECTIVE:

To examine treatment indications, efficacy and side effects of oral beta-blockers for the treatment of problematic hemangiomas.

METHODS:

A retrospective review of patients with hemangiomas presenting to the Alberta Children’s Hospital Vascular Birthmark Clinic (Calgary, Alberta) between 2009 and 2011 was conducted. The subset of patients treated with oral beta-blockers was further characterized, investigating indication for treatment, response to treatment, time to resolution of indication, duration of treatment, occurrence of rebound growth and side effects of therapy.

RESULTS:

Between 2009 and 2011, 311 new patients with hemangiomas were seen, of whom 105 were treated with oral beta-blockers. Forty-five patients completed beta-blocker treatment while the remainder continue to receive therapy. Indications for treatment were either functional concerns (68.6%) or disfigurement (31.4%). Functional concerns included ulceration (29.5%), periocular location with potential for visual interference (28.6%), airway interference (4.8%), PHACES syndrome (3.8%), auditory interference (0.95%) and visceral location with congestive heart failure (0.95%). The median age at beta-blocker initiation was 3.3 months; median duration of therapy was 10.6 months; and median maximal treatment dose was 1.5 mg/kg/day for propranolol and 1.6 mg/kg/day for atenolol. Ninety-nine patients (94.3%) responded to therapy with size reduction, colour changes, softened texture and/or healing of ulceration. Rebound growth requiring an additional course of therapy was observed in 23 patients. Side effects from beta-blockers included cool extremities (26.7%), irritability (17.1%), lower gastrointestinal upset (14.3%), emesis (11.4%), hypotension (10.5%), poor feeding (7.6%), lethargy (4.8%), bronchospasm (0.95%) and rash (0.95%). Side effects did not result in complete discontinuation of beta-blocker treatment in any case; however, they prompted a switch to a different beta-blocker preparation in some cases. Resolution of the primary indication, requiring a median time of three months, occurred in 87 individuals (82.9%).

CONCLUSIONS:

Treatment of infantile hemangiomas with oral beta-blocker therapy is highly effective and well tolerated, with more than 94% of patients demonstrating a response to treatment and 90% showing resolution of the primary functional indication for treatment.     

The effect of staff training on the use of restraint in dementia: a single-blind randomised controlled trial

BACKGROUND: Use of restraint amongst institutionalised elderly with dementia and problem behaviour not only remains widespread, but also appears to be accepted as inevitable. OBJECTIVE: The aim of this study was to reduce problem behaviour and the use of restraint in demented patients using a staff training program as intervention. METHODS: The study was a randomised single-blind controlled trial and took place in Stavanger, Norway. Four nursing homes were randomised to a control or an intervention group after stratification for size. The intervention consisted of a full day seminar, followed by a one-hour session of guidance per month over six months. The content of the educational program focused on the decision making process in the use of restraint and alternatives to restraint consistent with professional practice and quality care. The primary outcome measures were number of restraints per patient in the nursing homes in one week and agitation as measured with the Brief Agitation Rating Scale (BARS). These were rated before and immediately after the intervention was completed. The assessments were performed blind to design and randomisation group. RESULTS: Clinical and demographic variables did not differ between the intervention and control groups at baseline. After the intervention period, the number of restraints had declined by 54% in the treatment group, and increased by 18% in the control group. The difference between the two groups was statistically significant ( p = 0.013). There was a trend towards higher BARS score in the intervention compared to the control group at follow up ( p = 0.052). CONCLUSION: Although the level of agitated behaviour remained unchanged or increased slightly, the educational program led to a significant reduction of the use of restraint in institutionalised elderly with dementia. These results suggest that educational programs can improve the quality of care of people with dementia.     

Helping motives in late modern society: values and attitudes among nursing students

This article reports a follow-up study of Norwegian nursing students entitled 'The helping motive an important goal for choosing nursing education'. It presents and discusses a significant ambiguity within the altruistic helping motive of 301 nursing students in the light of classical and modern virtue ethics. A quantitative longitudinal survey design was used to study socialization and building professional identity. The follow-up study began after respondents had completed more than two-and-a-half years of the three-year educational programme. Data were collected using a questionnaire with closed questions, supplemented by 18 semi-structured, in-depth, audiotaped interviews. A motive such as 'desire for human contact/to help others' appeared to be highly significant. The research questions employed were: What motivates nursing students at the end of their studies to help other people? What does helping others mean for nursing students? Factor analysis revealed two factors. Factor 1 can be expressed as an altruism factor and factor 2 can be interpreted as an 'acknowledgement-from-the-patient factor' that in fact indicates an ambiguity within the helping motive itself. Findings from the interviews also reveal ambiguous helping motives. On one hand the students want to be altruistic and on the other they wish to receive positive feedback from patients when giving help. The findings indicate that this positive feedback is essential to the students in order for them to provide altruistic care.     

How do nursing students regard their future career? Career preferences in the post-modern society

This article presents findings from a study of 301 Norwegian nursing students' opinions of their future career. The initial survey took place 7 months after the commencement of nursing training in 1998/99 with a follow-up after 2 1/2 years. Data was collated using a questionnaire with closed questions and supplemented by semi-structured in-depth, audio taped interviews concerning the students' professional socialisation. The findings from the initial survey indicate that motives like human contact, helping others and job security (i.e. low risk of being laid off) were important. Plans for further education after finishing the bachelor programme in nursing were abundant. Analysis of the second data-set will show whether there is a change in the students' plans for their future education and career. For nearly 80% of the students it was very important that the bachelor degree could serve as a basis for further education. Multiple regression analysis showed that nursing students who emphasise this importance are less interested in giving care and help to others, and this attitude is confirmed in the interviews. Career preferences were often midwifery, public health or practice in high tech areas like anaesthetics, and not care for chronically ill or elderly patients; areas where there is a shortage of nurses.     

Co-expression of the genes encoding transforming growth factor-alpha and its receptor in papillary carcinomas of the thyroid.

Transforming growth factor-alpha (TGF-alpha) is frequently coexpressed with its receptor, epidermal growth factor receptor (EGF-R), in several types of carcinoma and sarcoma. It is believed that this results in an autocrine stimulation of tumor growth in these tumors. We have found that TGF-alpha and EGF-R/c-erbB RNAs were co-expressed at significantly higher levels in papillary thyroid carcinomas and their lymph-node metastases than in non-neoplastic thyroid tissues. We also observed a low level of expression of RNA specific for insulin-like growth factor I in these tumors, which was highest in a lymph-node metastasis. Autocrine stimulation by TGF-alpha may thus be a common feature of papillary carcinomas of the thyroid. Since EGF is known to induce proliferation and dedifferentiation of normal thyroid cells in culture, TGF-alpha and its receptor may play an important role in thyroid carcinogenesis.
