Ancestry reported by white adults with cutaneous melanoma and control subjects in central Alabama

Background  

We sought to evaluate the hypothesis that the high incidence of cutaneous melanoma in white persons in central Alabama is associated with a predominance of Irish and Scots descent.     

Suspected poisoning in children. Study of the incidence of true poisoning and poisoning scare in a defined population in North East Bristol

The distinction between true and suspected poisoning in children has not been made clear in previous work on childhood poisoning. A study of suspected poisoning in children under 15 years of age in a defined population of North East Bristol from November 1970 to July 1973 carried out by the Health Education Council Medical Research Division included 53,000 child-years at risk. The number of suspected poisonings was 3-4/1000 population aged under 15 years per year, with a higher incidence in younger age groups. Detailed investigation of the circumstances of the accidents carried out by a multidisciplinary team showed that at least 65%, and possibly as many as 78% were poisoning scares and not true poisoning. The evidence used by the casualty doctor and by the parents to diagnose poisoning was explored, and in many cases was circumstantial. Children with fathers in nonmanual occupations were over-represented. This may reflect differences in patterns of utilization behaviour rather than true differences in incidence.     

Serum levels of insulin-like growth factor binding proteins in Ecuadorean children with growth hormone insensitivity

Burren CP, Wanek D, Mohan S, Cohen P, Guevara-Aguirre J, Rosenfeld RG. Serum levels of insulin-like growth factor binding proteins in Ecuadorean children with growth hormone insensitivity. Acta Pædiatr 1999; Suppl 428: 185–91. Stockholm. ISSN 0803–5326
Although insulin-like growth factor binding proteins (IGFBPs) are known to be important modulators of the action of insulin-like growth factors (IGFs), regulation of their production in vivo is not completely understood. Serum concentrations of IGFBP-3, -4 and -5 and acid-labile subunit (ALS) were therefore examined in 20 children with growth hormone (GH) insensitivity before and after 6 months of therapy with recombinant human IGF-I (80 or 120 ug/kg twice daily). The IGFBP concentrations in these children were compared with those in 62 GH-deficient children receiving GH therapy for 3 months. Serum levels of IGFBP-3, -4 and -5 and ALS all increased significantly ( p < 0.0001) in GH-deficient children in response to GH therapy, whereas no significant increases occurred in the children with GH insensitivity. These findings indicate that GH is responsible for the regulation of serum levels of IGFBP-3, -4 and -5 and ALS, and that IGF-I does not directly regulate the concentrations of these circulating IGFBPs. □ Growth hormone, growth hormone insensitivity, insulin-like growth factor I, insulin-like growth factor binding protein     

Patient and Physician Factors Contributing to Poor Outcomes in Patients with Asthma and COPD

Poor adherence with medical regimens by patients with asthma and chronic obstructive pulmonary disease (COPD) is a major problem facing medical practitioners, with patients typically taking approximately half the prescribed doses of self-administered medications. Poor adherence with medication regimens results in inadequate disease control and is assumed to be associated with poor long-term outcomes and high medical and social costs. Efforts to assist patients with treatment adherence are thought to improve the benefits of prescribed medications; however, even the most effective interventions do not necessarily lead to significant improvements in adherence and treatment outcomes.Simple interventions (such as re-calling patients who miss appointments, making every effort to keep patients in care, and simplifying treatment regimens) and complex strategies (including combinations of more thorough patient instructions and counseling, reminders, close follow-up, supervised self-monitoring, family therapy, crisis intervention, and telephone follow-up) may improve adherence and treatment outcomes for both short- and long-term treatments. All these measures are highly dependent on a good physician-patient relationship, and the willingness and ability of caregivers to closely follow guidelines and recommendations.The diversity and complexity of interventions, and uncertainty about their effects, make it difficult to assess which interventions are effective and which are not. The literature regarding interventions remains surprisingly limited. There is little evidence to show that medication adherence can be improved consistently, or that interventions will inevitably lead to improvements in treatment outcomes, especially considering the resources usually available in outpatient settings. Most studies assessing successful complex interventions have not assessed the effect on clinical endpoints. Studies in COPD are sparse compared with those in asthma, leaving room for further research efforts. As all self-administered treatments are affected by low adherence, and as the number of efficacious, self-administered treatments continues to grow, detailed knowledge about this complex issue may help to ensure better management in patients with obstructive pulmonary diseases.     

Effect of inpatient psychiatry training on internal medicine residents. Results of a survey

Forty-two residents in internal medicine completed an attitudinal survey at the beginning and end of a 2-month inpatient psychiatry rotation. Residents noted a significant increase in their confidence regarding the management of various psychiatric problems and personality problems, the conducting of supportive counseling, the making of psychiatric referrals, the usefulness of psychotherapy, and the ability to discuss emotionally difficult subjects with patients. The rotation was perceived as being worthwhile and enjoyable. Areas of uncertainty that remained included concern regarding the time demands, the perception that psychiatric patients are anxiety-provoking and difficult to treat, and that psychiatric knowledge was an extension of common sense.     

Dysphagia as the Sole Manifestation of Bilateral Strokes

Dysphagia can be caused by a host of factors, most of which are structural or functional. However, despite extensive evaluations, a certain number of patients have unexplained dysphagia. We present an extremely unusual case whereby a patient with an acute left hemispheric cerebral vascular accident presents with dysphagia as his sole complaint and after extensive neurological, gastroenterological, and radiographic examinations is found to have cricopharyngeal dysfunction. The etiology of this defect was not at all clinically apparent and, ultimately, magnetic resonance imaging (MRI) was performed which revealed a chronic infarction of the right frontal lobe and a smaller acute infarction in the same location of the left. This case demonstrates that swallowing disorders may be the sole presentation of stroke and that, if extensive evaluations of such patients fail to yield an etiology, one must strongly consider MRI as a tool for diagnosis, even if a CT scan is negative.     

Right ventricular perforation with cardiac tamponade associated with use of a temporary pacing wire and abciximab during complex coronary angioplasty.

We describe our recent experience of right ventricular perforation leading to cardiac tamponade associated with a complex coronary angioplasty in which abciximab and a temporary pacing wire were used. This is to highlight the possibility that the combined use of temporary pacing wires and the IIb/IIIa receptor antagonists may be associated with an increased risk of this serious complication.

Research priorities in spasmodic dysphonia

OBJECTIVE: To identify research priorities to increase understanding of the pathogenesis, diagnosis, and improved treatment of spasmodic dysphonia. STUDY DESIGN AND SETTING: A multidisciplinary working group was formed that included both scientists and clinicians from multiple disciplines (otolaryngology, neurology, speech pathology, genetics, and neuroscience) to review currently available information on spasmodic dysphonia and to identify research priorities. RESULTS: Operational definitions for spasmodic dysphonia at different levels of certainty were recommended for diagnosis and recommendations made for a multicenter multidisciplinary validation study. CONCLUSIONS: The highest priority is to characterize the disorder and identify risk factors that may contribute to its onset. Future research should compare and contrast spasmodic dysphonia with other forms of focal dystonia. Development of animal models is recommended to explore hypotheses related to pathogenesis. Improved understanding of the pathophysiology of spasmodic dysphonia should provide the basis for developing new treatment options and exploratory clinical trials. SIGNIFICANCE: This document should foster future research to improve the care of patients with this chronic debilitating voice and speech disorder by otolaryngology, neurology, and speech pathology.
