Parent beliefs about infant teething: a survey of Australian parents

OBJECTIVE: Parents ascribe many infant symptoms to teething, despite little evidence to support such an attribution. We report current parental beliefs about teething and its management in a suburban Australian setting. METHODOLOGY: A written questionnaire was given to all English-speaking parents consecutively attending infant hearing testing sessions in one Melbourne municipality between August and October 1997. Approximately 90% of Victorian infants attend these sessions. RESULTS: Parents of 92 infants (mean age 9.9 months) completed questionnaires (97% response rate). Only one believed that teething causes no problems. Most (70-85%) believed that teething causes fever, pain, irritability, sleep disturbance, mouthing/biting, drooling and red cheeks; 35-55% reported nappy rash, 'sooking', ear pulling, feeding problems, runny nose, loose stools, and infections; and a few (< 15%) reported smelly urine, constipation, colic or convulsions. Symptoms reported for a parent's own infant correlated almost perfectly with symptoms believed to be experienced by infants generally (r = 0.97, P < 0.001). Amount of infant distress when teething correlated with more 'difficult' infant temperament (r = 0.25, P < 0.05), and longer duration of symptoms per tooth correlated with parent distress (r = 0.26, P < 0. 05). Paracetamol (60%) and topical analgesia (55%) were commonly used remedies. Parents diagnose teething more by the presence of 'teething symptoms' (65%) than by palpable (43%) or visible (36%) tooth eruption. CONCLUSION: Teething is a distressing but ill-defined phenomenon reported by almost all parents of young children, and most use some form of medication to manage it. Most symptoms are minor and relate to discomfort rather than physical illness, but a substantial minority still ascribes potentially serious symptoms to teething.     

Paclitaxel and concurrent radiation for gastric cancer

PURPOSE: To determine the activity and toxicity of paclitaxel and concurrent radiation for gastric cancer. METHODS AND MATERIALS: Twenty-seven patients were studied. Twenty-five had proximal gastric cancers, two had distal cancers. Eight had esophageal extension, 6 had celiac adenopathy, and 7 had retroperitoneal adenopathy. Patients received paclitaxel, 50 mg/m(2) by 3-hour intravenous (IV) infusion, weekly, on days 1, 8, 15, 22, and 29. Radiation was administered concurrently to a total dose of 45.0 Gy, in 1.80 Gy fractions, for 25 treatments. Patients who were medically or surgically inoperable received a sixth week of paclitaxel with a radiation boost to 50.4 Gy. RESULTS: Esophagitis and gastritis were the most important toxicities, Grade 3 in four patients (15%), and Grade 4 in three patients (11%). Five patients (19%) had Grade 3 nausea. The overall response rate was 56%, including three patients (11%) with a complete response. The 2-year progression-free and overall survival rates were 29% and 31%, respectively. CONCLUSION: Concurrent paclitaxel and radiation demonstrates substantial local-regional activity in gastric cancer. Future investigations combining paclitaxel and radiation with other local-regional and systemic treatments are warranted.     

The oral NK(1) antagonist aprepitant for the prevention of acute and delayed chemotherapy-induced nausea and vomiting: Pooled data from 2 randomised, double-blind, placebo controlled trials

In this work, data from two phase III studies were pooled to further evaluate the NK(1) antagonist aprepitant for prevention of cisplatin induced nausea and vomiting. One thousand and forty three patients receiving cisplatin (> or = 70 mg/m2) were randomised to receive either a control regimen (32 mg intravenous ondansetron [O] and 20 mg oral dexamethasone [D] on day 1; 8 mg D twice daily on days 2-4) or an aprepitant (A) regimen (125 mg A plus 32 mg O and 12 mg D on day 1, 80 mg A and 8 mg D once daily on days 2-3, and 8 mg D on day 4). The primary endpoint was no emesis and no rescue therapy. Potential correlations between acute and delayed emesis were assessed, as were frequency of emetic episodes by time interval and effects on nausea and quality of life as measured by the functional living index emesis (FLIE) questionnaire. In the aprepitant group, there was statistically significantly less nausea over the study period as well as higher functioning on the FLIE questionnaire in both the nausea and vomiting domains. Patients without acute emesis were more likely to have no emesis in the delayed phase. Compared with control, the aprepitant regimen improved prevention of delayed emesis by 16% points in patients without acute emesis, and by 17% points in patients with acute emesis. Among patients who did not have complete response, the frequency of emesis at various intervals over 5 days was consistently lower in patients receiving aprepitant. Analyses of this combined Phase III population further characterized the clinical profile of the aprepitant regimen, showing that delayed emesis is correlated with, but not entirely dependent on, the presence of acute emesis, and that aprepitant has a favorable effect against nausea throughout 5 days postchemotherapy. In addition, even among patients who had emesis or needed rescue therapy, aprepitant was associated with a lower frequency of these events compared with the control regimen.     

Novel targets for cardiac antiarrhythmic drug development

Cardiac arrhythmias remain a major source of morbidity and mortality in developed countries. Antiarrhythmic drug therapy was traditionally the mainstay of cardiac arrhythmia treatment; however, drug therapy of cardiac arrhythmias has been plagued by incomplete efficacy and by potentially serious adverse reactions, of which the most worrisome has been a potential for malignant proarrhythmia and related effects to increase cardiac mortality. This article reviews the principal arrhythmia mechanisms and their ionic determinants, and discusses potential innovative approaches to new antiarrhythmic drug development, including the consideration of novel ionic targets, potential biophysical approaches and non-channel components involved in composing the arrhythmic substrate.     

Healthy eating, activity and obesity prevention: a qualitative study of parent and child perceptions in Australia

Preventative health strategies incorporating the views of target participants have improved the likelihood of success. This qualitative study aimed to elicit child and parent views regarding social and environmental barriers to healthy eating, physical activity and child obesity prevention programmes, acceptable foci, and appropriate modes of delivery. To obtain views across a range of social circumstances three demographically diverse primary schools in Victoria, Australia were selected. Children in Grades 2 (aged 7-8 years) and 5 (aged 10-11 years) participated in focus groups of three to six children. Groups were semi-structured using photo-based activities to initiate discussion. Focus groups with established parent groups were also conducted. Comments were recorded, collated, and themes extracted using grounded theory. 119 children and 17 parents participated. Nine themes emerged: information and awareness, contradiction between knowledge and behaviour, lifestyle balance, local environment, barriers to a healthy lifestyle, contradictory messages, myths, roles of the school and family, and timing and content of prevention strategies for childhood obesity. In conclusion, awareness of food 'healthiness' was high however perceptions of the 'healthiness' of some sedentary activities that are otherwise of benefit (e.g. reading) were uncertain. The contradictions in messages children receive were reported to be a barrier to a healthy lifestyle. Parent recommendations regarding the timing and content of childhood obesity prevention strategies were consistent with quantitative research. Contradictions in the explicit and implicit messages children receive around diet and physical activity need to be prevented. Consistent promotion of healthy food and activity choices across settings is core to population prevention programmes for childhood obesity.     

Late presentation of an iatrogenic circumflex to left atrial fistula closed with a covered stent

An anomalous circumflex to left atria fistula following previous excision of an atrial myxoma was successfully occluded percutaneously using a covered stent. The intervention was technically challenging but was possible using a Magnum guide wire via a left radial approach.
