Indicators of choking risk in adults with learning disabilities: a questionnaire survey and interview study

Purpose. Feeding and swallowing impairments are key predictors of increased morbidity and mortality in adults with learning disabilities. This postal survey and interview study sought to identify risk factors in adults with learning disabilities who have histories of choking. Method. A total of 2000 questionnaires were sent to carers of all adults with learning disabilities registered as service users by three local health authorities. (A 'service user' may be using any specialist learning disability health or social care facility with day, residential or therapeutic services). Of the 674 service users for whom surveys were returned, 47 were living in hospital, 396 were living in residential or group homes and 208 were living with relatives, or in their own homes. Eighteen subjects who had reported serious or repeated episodes of choking were interviewed in depth in their residences or workplaces. Responses were subjected to frequency analyses. Personal characteristics were analysed. Choking patterns were differentiated by food texture. Results. A total of 34% of questionnaires on 674 service users were returned; 42% of respondents reported one or more choking episodes. There was a significantly greater occurrence of choking among people with more severe learning disability, with Down syndrome, people who had an incomplete dentition or were taking a greater number of psychotropic drugs. Antisocial eating habits learnt in institutional settings presented an additional choking hazard for some individuals. Conclusion. Choking is a serious hazard for many adults with learning disabilities. This study establishes many of the characteristics associated with swallowing problems in this population. Clinicians and carers should benefit from awareness of these predictors, leading to better management of eating behaviours and habits. A choking and swallowing risk assessment should be included in routine health assessments of adults with learning disability, paying especial attention to the condition of a person's teeth; possible side effects from prescribed medication, and abnormal eating behaviour.     

Orthopedic management of the extremities in patients with Morquio A syndrome

Background

Musculoskeletal involvement in Morquio A syndrome (mucopolysaccharidosis IVA; MPS IVA) contributes significantly to morbidity and mortality. While the spinal manifestations of the disorder have received considerable attention in the literature, there have been few reported studies to date to guide the management of the orthopedic problems associated with the lower and upper extremities.

Purpose

The objective was to develop recommendations for the management of the extremities in patients with Morquio A syndrome.

Methods

A group of specialists in orthopedics, pediatrics and genetics with experience in the management of Morquio A patients convened to review and discuss current clinical practices and to develop preliminary recommendations. Evidence from the literature was retrieved. Recommendations were further refined until consensus was reached.

Results and conclusions

This present article provides a detailed review and discussion of the lower and upper extremity deformities in Morquio A syndrome and presents recommendations for the assessment and treatment of these complications. Key issues, including the importance of early diagnosis and the implications of medical therapy, are also addressed. The recommendations herein represent an attempt to develop a uniform and practical approach to managing patients with Morquio A syndrome and improving their outcomes.     

Imaging of pediatric liver tumors: A COG Diagnostic Imaging Committee/SPR Oncology Committee White Paper

Primary hepatic malignancies are relatively rare in the pediatric population, accounting for approximately 1%–2% of all pediatric tumors. Hepatoblastoma and hepatocellular carcinoma are the most common primary liver malignancies in children under the age of 5 years and over the age of 10 years, respectively. This paper provides consensus-based imaging recommendations for evaluation of patients with primary hepatic malignancies at diagnosis and follow-up during and after therapy.     

Biomechanics of a new atraumatic surgical needle holder

It is the purpose of this report to design, develop, and evaluate a needle holder whose jaws improve needle-holding security without altering the geometry of the curved surgical needle. The configuration of the jaws of this new needle holder is curved, conforming to the curvature of the surgical needle. A biomechanical study of this curved surgical needle holder demonstrates that it holds the curved needle securely without needle deformation.
