The Next Wave: Confexting

Radiology conferences enable participants the opportunity to ask experts questions through question and answer (Q and A) sessions or individually. Given the time limitations and intimidating circumstances, we incorporated conference text messaging (confexting) as a method of increasing interactivity between the audience and speakers. During a 5-day radiology conference, text messaging was utilized for anonymous interactivity between the audience and speakers during Q and A sessions. There were 324 text messages; 76 of these were either follow-up statements or questions related to earlier text messages. Forty-two questions were submitted via paper notes. There was a general trend of an increasing number of text messages and a decreasing number of paper notes. The anonymous text messaging system was found to be an effective method for interactivity between the audience and the speakers. The questions and answers could be presented in a PowerPoint format at the formal Q and A sessions. Questions texted to the authors during their talks could be immediately answered or addressed in subsequent talks. Although difficult for some individuals to embrace technology, confexting allows for interactivity and prompts discussion. Confexting is an effective method for interactivity between the audience and speakers not previously utilized in a conference setting. The anonymity and asynchronous communication enable conference participants to submit more questions than in the traditional setting. The speakers may be able to explain more thoroughly difficult concepts more thoroughly with additional slides at Q and A sessions or may immediately answer texted questions during their talks.     

The role of palliative care in advanced muscular dystrophy and spinal muscular atrophy

OBJECTIVE: This study examines the potential role for palliative care services in the care of individuals with muscular dystrophy and spinal muscular atrophy, and the support of their families. METHODOLOGY: Semistructured interviews were conducted in South Australia with nine bereaved and four current family members of individuals with muscular dystrophy or spinal muscular atrophy. Issues explored during interview included: (i) the family perceptions of the difficulties in caring; (ii) the psychological and physical resources which were available to assist them; and (iii) family recall of the management of the terminal phase of the illness. RESULTS: Significant issues identified included: (i) a lack of coordination of care and access to skilled, competent carers; (ii) a lack of support for siblings; (iii) inadequate bereavement care; and (iv) limited discussion of options of ventilatory support and advance directives. CONCLUSIONS: The terminal care for individuals with muscular dystrophy and spinal muscular atrophy and their families requires improvement. Although many individuals with these conditions will die following an acute event, palliative care services may be appropriate for those who require a period of terminal care at home.

Homeopathy: A State of the Science Review With Recommendations for Practical Therapies in Midwifery Practice

A substantial proportion of adults and children in the United States use complementary and alternative health practices, including homeopathy. Many homeopathic therapies are readily available over the counter, and many individuals access and self-administer these therapies with little or no guidance from health care practitioners. In addition, patients and health care providers are often confused by terminologies associated with complementary practices and may be unable to distinguish homeopathy from naturopathy, herbalism, holistic medicine, Ayurveda, traditional Chinese medicine, or other forms of health care. Compared with European and Asian countries, education in the United States about complementary and alternative health practices is not typically found within traditional nursing, midwifery, or medical education curricula. Given this lack of education and the broad acceptance and popularity of homeopathy, it is necessary for health care practitioners to improve their knowledge regarding similarities and differences among therapies so they can fully inform and make appropriate recommendations to patients. The intent of this article is therefore to examine the state of existing science of homeopathy, distinguish it from other complementary methods, and provide midwives and women's health care providers with an introduction to common homeopathic therapies that may be recommended and safely used by persons seeking midwifery care. This review also presents the evidence base, pharmacology, manufacturing, and regulation of homeopathic therapies. We also consider controversies and misunderstandings regarding safety and efficacy of homeopathic remedies relevant to women and birthing persons. Examples of practical applications of homeopathic therapies for use in midwifery practice are introduced. Implications for practice and sample guidelines are included.     

Unmappable ventricular tachycardia after an old myocardial infarction. Long-term results of substrate modification in patients with an implantable cardioverter defibrillator

Purpose  

The frequent occurrence of ventricular tachycardia can create a serious problem in patients with an implantable cardioverter defibrillator. We assessed the long-term efficacy of catheter-based substrate modification using the voltage mapping technique of infarct-related ventricular tachycardia and recurrent device therapy.     

Prevalence of apical periodontitis detected in cone beam CT images of a Brazilian subpopulation

Objectives

The aim of this study was to determine the prevalence of apical periodontitis (AP) detected in cone beam CT (CBCT) images from a database.

Methods

CBCT images of 300 Brazilian patients were assessed. AP images were measured in three dimensions. Age, gender, number and location of total teeth in each patient were considered. AP location was considered according to tooth groups. The extent of AP was determined by the largest diameter in any of the three dimensions. Percentages and the χ² test were used for statistical analysis.

Results

AP was found in 51.4% of the patients and in 3.4% of the teeth. Higher prevalence of AP was found in 60- to 69-year-olds (73.1%) and in mandibular molars (5.9%) (p < 0.05). Inadequate endodontic treatment presented higher prevalence of AP (78.1%).

Conclusions

AP can be frequently found in CBCT examinations. The presence of AP has a significant association with patients'' age, and tooth type and condition. CBCT databases are useful for cross-sectional studies about AP prevalence in a population.
