Dental education and dentists' attitudes and behavior concerning patients with autism

The number of patients diagnosed with autism spectrum disorders (ASD) in the United States has increased significantly. The objectives of this study were to explore general and pediatric dentists' professional attitudes and behavior towards patients with ASD; these dentists' perceptions of their dental education about these issues; and the relationships among their educational experiences, attitudes, and behaviors concerning patients with ASD. Survey data were collected from 162 general dentists in Michigan and 212 pediatric dentists across the United States. The results showed that 89 percent of pediatric dentists and 32 percent of general dentists treat patients with ASD. The respondents disagreed with statements indicating that their predoctoral dental education had prepared them well to treat patients with ASD. However, the better they felt prepared, the more likely they were to provide care for these patients. The frequency with which pediatric dentists said they use appropriate behavior management strategies when treating patients with ASD correlated with the quality of their educational experiences. In conclusion, given the growing number of patients with ASD, it is important to revisit dental education efforts targeted towards preparing future dental care providers for the treatment of patients with ASD and special needs.     

Transitioning patients from cangrelor to clopidogrel: pharmacodynamic evidence of a competitive effect

BACKGROUND: Cangrelor is a direct, parenteral, and reversible inhibitor of the platelet P2Y12 receptor currently undergoing Phase III testing. As many individuals treated acutely with cangrelor will often be treated long-term with a thienopyridine, it is important to determine the effects of concurrent cangrelor and clopidogrel administration. METHODS AND RESULTS: Ten healthy volunteers received a 600 mg oral loading dose of clopidogrel and then underwent serial platelet function monitoring for 6 h. Two weeks later these same individuals received a 600 mg clopidogrel loading dose simultaneously with a cangrelor IV bolus (30 microg/kg) and a 2-hour infusion (4 microg/kg/min). A separate group of ten volunteers received a 600 mg clopidogrel loading dose after administration of a cangrelor bolus and a 1-hour infusion. The effects on ADP-induced platelet activation and aggregation were evaluated by flow cytometry, whole-blood electrical impedance, and light-transmittance aggregometry. Cangrelor and clopidogrel alone achieved the expected levels of platelet inhibition. However, the sustained platelet inhibition anticipated for clopidogrel treatment did not occur when cangrelor was initiated simultaneously. No such effect was found when clopidogrel was started upon completion of the cangrelor infusion. CONCLUSION: To achieve sustained platelet P2Y12 inhibition in patients treated with cangrelor, clopidogrel administration should be started when the cangrelor infusion is terminated.     

Alliance not compliance: coaching strategies to improve type 2 diabetes outcomes

PURPOSE: To explore strategies for improving patient outcomes in type 2 diabetes. DATA SOURCES: The literature related to type 2 diabetes management, behavior change, communication, diabetes self-management, and coaching. CONCLUSIONS: The strategies currently suggested for improving patient outcomes, e.g., increasing provider adherence to evidence-based management guidelines, streamlining practice systems, and promoting patient lifestyle changes through intensive education, have produced mixed outcomes. Of the many complexities involved in managing type 2 diabetes, motivating patients to change behavior may be the most challenging. A suggestion for improving patient self-management of type 2 diabetes is to use coaching communication within a framework of behavior change in the context of the primary care encounter between nurse practitioners (NPs) and their patients. IMPLICATIONS FOR PRACTICE: Given the varied outcomes of current strategies, coaching by NPs may provide a feasible alternative for improving patient outcomes in type 2 diabetes. Coaching communication can be implemented during office visits as an intervention without cost. To effectively implement this approach, however, practicing NPs and NP students need more formal education in this expected but underdeveloped NP role competency. NPs are called upon to contribute to the body of knowledge needed to validate the merits of coaching for their patients.     

Fluoxetine versus placebo in preventing relapse of major depression in children and adolescents

OBJECTIVE: The authors compared fluoxetine and placebo in continuation treatment to prevent relapse of major depressive disorder in children and adolescents. METHOD: After a detailed evaluation, children and adolescents 7-18 years of age with major depressive disorder were treated openly with fluoxetine. Those who had an adequate response after 12 weeks, as indicated by a Clinical Global Impression improvement score of 1 or 2 and a decrease of at least 50% in Children's Depression Rating Scale-Revised score, were randomly assigned to receive fluoxetine or placebo for an additional 6 months. The primary outcome measures were relapse and time to relapse. Relapse was defined as either a score of 40 or higher on the Children's Depression Rating Scale with a history of 2 weeks of clinical deterioration, or clinical deterioration as judged by the clinician. Additional analyses were conducted with relapse defined only as a score of 40 or higher on the Children's Depression Rating Scale. RESULTS: Of 168 participants enrolled in acute fluoxetine treatment, 102 were randomly assigned to continuation treatment with fluoxetine (N=50) or placebo (N=52). Of these, 21 participants (42.0%) in the fluoxetine group relapsed, compared with 36 (69.2%) in the placebo group, a significant difference. Similarly, under the stricter definition of relapse, fewer participants in the fluoxetine group relapsed (N=11; 22.0%) than in the placebo group (N=25; 48.1%). Time to relapse was significantly shorter in the placebo group. CONCLUSIONS: Continuation treatment with fluoxetine was superior to placebo in preventing relapse and in increasing time to relapse in children and adolescents with major depression.     

Seltene akute Krankheitsbilder der oberen Atemwege bei Kindern

The radiologist should recognize dangerous uncommon conditions such as epiglottitis and membranous croup by their pattern on conventional images. Subglottic narrowing, as from croup, is recognizable on lateral images by loss of the superior interface of trachea and vocal cords. A lateral image is important when an upper esophageal foreign body is seen on a frontal view.     

Spectrum and natural history of congenital hyperparathyroidism secondary to maternal hypocalcemia

Fourteen cases of congenital hyperparathyroidism secondary to maternal hypocalcemia have been reported. We report two additional cases that highlight the wide spectrum of the disease. We extensively studied the parathyroid function of these infants to test the hypothesis that the biochemical hyperparathyroidism found in these infants would be transient in nature, since the presumed etiology (maternal and subsequent fetal hypocalcemia) should disappear soon after birth with establishment of enteral feedings. Infant 1 was born to a mother with idiopathic hypoparathyroidism with poor compliance to therapy and documented hypocalcemia in pregnancy. Severe congenital demineralization and intrauterine fractures with clinical and radiologic bowing of the long bones were obvious. Bone mineral content and bone mineral content/bone width ratio, measured by photon absorptiometry, were both markedly below normal. Infant 2 was born to a mother with postsurgical hypoparathyroidism with excellent compliance. The mother was normocalcemic. The infant was clinically and radiologically asymptomatic. The bone mineral content was just at the lower limit of normal, but bone mineral content/bone width ratio was below the normal limits. Biochemical features include elevation of cord serum parathyroid hormone (1-84, radioimmunoassay) in both cases, coexisting with serum calcium, phosphorus concentrations within normal limits. Serum parathyroid hormone fell to within normal ranges by 9 days of age in both infants. With no treatment, bone mineral content at 1 month of age was normal in both infants.     

Public-private partnerships to build human capacity in low income countries: findings from the Pfizer program

Background

The ability of health organizations in developing countries to expand access to quality services depends in large part on organizational and human capacity. Capacity building includes professional development of staff, as well as efforts to create working environments conducive to high levels of performance. The current study evaluated an approach to public-private partnership where corporate volunteers give technical assistance to improve organizational and staff performance. From 2003 to 2005, the Pfizer Global Health Fellows program sent 72 employees to work with organizations in 19 countries. This evaluation was designed to assess program impact.

Methods

The researchers administered a survey to 60 Fellows and 48 Pfizer Supervisors. In addition, the team conducted over 100 interviews with partner organization staff and other key informants during site visits in Uganda, Kenya, Ghana, South Africa and India, the five countries where 60% of Fellows were placed.

Results

Over three-quarters of Fellowships appear to have imparted skills or enhanced operations of NGOs in HIV/AIDS and other health programs. Overall, 79% of Fellows reported meeting all or most technical assistance goals. Partner organization staff reported that the Fellows provided training to clinical and research personnel; strengthened laboratory, pharmacy, financial control, and human resource management systems; and helped expand Partner organization networks. Local staff also reported the Program changed their work habits and attitudes. The evaluation identified problems in defining goals of Fellowships and matching Organizations with Fellows. Capacity building success also appears related to size and sophistication of partner organization.

Conclusion

Public expectations have grown regarding the role corporations should play in improving health systems in developing countries. Corporate philanthropy programs based on "donations" of personnel can help build the organizational and human capacity of frontline agencies delivering health services. More attention is needed to measure and compare outcomes of international volunteering programs, and to identify appropriate strategies for expansion.
