The patient assessment questionnaire: a new instrument for evaluating the interpersonal skills of vocational dental practitioners

This paper describes a pilot study aimed at evaluating a new instrument, the patient assessment questionnaire (PAQ), which uses patient ratings for the assessment of communication skills and professionalism in vocational practitioners (VDPs). The PAQ was developed as part of an assessment system designed to address all round competence. Acohort of 99 VDPs took part in the study. Questionnaires were distributed to consecutive patients in the general dental service at two time points in the training year. Data from the pilot study was analysed to determine whether the PAQ fulfilled the criteria for robust assessment. Results provide evidence of high levels of reliability, validity and feasibility of the PAQ instrument. All indications to date suggest that the PAQ will prove to be a valuable assessment tool. It is currently being evaluated as part of the system used to assess the all round competence of dental graduates undertaking vocational training in Scotland.     

Around-the-clock: parent work schedules and children's well-being in a 24-h economy

Family life in developed economies has undergone a fundamental change--shifting from single-breadwinner households (typical of the post war decades) to families where both parents are employed. Equally dramatic has been the emergence of around-the-clock economies, altering the way work is organised, especially working time. Many more children now live in households where one or both parents work non-standard hours (evenings, nights or on weekends). Are there any implications for children's well-being when parents work non-standard schedules? There has been virtually no investigation of how children are faring in these around-the-clock households, despite evidence that non-standard work times affect family functioning and are stressful for parents. Using data from a representative sample of 4433 dual-earner Canadian families and their 2--11-year-old children (N children=6361), we compared families where both parents worked standard hours, with families where one or both worked non-standard times (evenings, nights or weekends). In nearly three-quarters of the families one or both parents regularly worked non-standard times. We found associations between children's well-being and parent work schedules, with higher odds ratios for child difficulties when parents worked non-standard times. These associations persisted after adjusting for several confounding factors including socio-economic status, parent part-time or full-time work, and childcare use, and were evident whether mothers, fathers or both parents worked non-standard times. The findings raise questions about the implications for children of the 24-h economy.     

Antitumor effectiveness of different amounts of electrical charge in Ehrlich and fibrosarcoma Sa-37 tumors

Background  

In vivo studies were conducted to quantify the effectiveness of low-level direct electric current for different amounts of electrical charge and the survival rate in fibrosarcoma Sa-37 and Ehrlich tumors, also the effect of direct electric in Ehrlich tumor was evaluate through the measurements of tumor volume and the peritumoral and tumoral findings.     

Respiratory distress in a neonate with an enlarged thymus

 Thymic hyperplasia, although not a rare condition in infancy, is usually asymptomatic. We describe an infant presenting in the perinatal period with marked tachypnoea. An enlarged thymus, demonstrated on chest radiograph and CT, was associated with small-volume, non-compliant lungs. Other causes of pulmonary malfunction and maldevelopment were excluded. Conclusion Thymic enlargement is unusually associated with neonatal respiratory distress but should be considered in the differential diagnosis.

Waist circumference is associated with pulmonary function in normal-weight, overweight, and obese subjects

BACKGROUND: Obesity is becoming a serious public health issue and is related to lung dysfunction. Because both weight and height are indicators of body size, body mass index (BMI) may not be an ideal index of obesity in prediction of pulmonary dysfunction. OBJECTIVE: The objective of the study was to determine the predictability of waist circumference (WC) and BMI for pulmonary function in adults with and without excess body weight. DESIGN: A cross-sectional study of 1674 adults aged > or = 18 y was conducted in a rural community. Height, weight, WC, and pulmonary function were measured. Multivariate analysis was conducted. RESULTS: WC was negatively associated with forced vital capacity and forced expiratory volume in 1 s, and the associations were consistent across sex, age, and BMI categories. On average, a 1-cm increase in WC was associated with a 13-mL reduction in forced vital capacity and an 11-mL reduction in forced expiratory volume in 1 s. The association between WC and pulmonary function was consistent in subjects with normal weight, overweight, and obesity. In subjects with normal weight, BMI was positively associated with forced vital capacity and forced expiratory volume in 1 s. CONCLUSION: WC, but not BMI, is negatively and consistently associated with pulmonary function in normal-weight, overweight, and obese subjects.
