Effects of phonemic awareness instruction on the encoding skills of children with severe speech impairment

Purpose: To examine the effects of phoneme-grapheme correspondence and phonemic awareness instruction on the encoding abilities of three pre-reading children with severe speech impairment (SSI). Method: Using a single subject multiple baseline design across behaviours and participants, children received phoneme-grapheme awareness instruction followed by instruction in segmenting, manipulating, and encoding consonant-vowel-consonant (CVC) pseudowords. Results: Generalization occurred to encoding of novel CVC pseudo- and real words for two of the three participants. Conclusions: Results suggest that phoneme-grapheme correspondence and phonemic awareness instruction is effective in developing encoding skills in children with SSI. Findings are consistent with those for other at-risk children.     

Endocannabinoids and Reactive Nitrogen and Oxygen Species in Neuropathologies

Neuropathologies that affect our population include ischemic stroke and neurodegenerative diseases of immune origin, including multiple sclerosis. The endocannabinoid system in the brain, including agonists anandamide (arachidonyl ethanolamide) and 2-arachidonoylglycerol, and the CB₁ and CB₂ cannabinoid receptors, has been implicated in the pathophysiology of these disease states, and can be a target for therapeutic interventions. This review concentrates on cellular signal transduction pathways believed to be involved in the cellular damage.Support: National Institute on Drug Abuse U24-DA12385 (S.M. and D.C.N.), R01-DA03690 and K05-00182 (A.C.H.), the American Heart Association Beginning Grant in Aid (S.M.), National Institute of General Medical Sciences S06 GM08049 (D.C.N.), and the National Center on Minority Health and Health Disparities P20-MD00175 (D.C.N. and A.C.H.).Meeting: Mechanisms of Toxicity, Toxicokinetics, and Medical Consequences of Drugs, Substances of Abuse and AIDS.

ICF linking rules: an update based on lessons learned.

OBJECTIVE: Outcome research seeks to understand the end results of health services. Researchers use a wide variety of outcome measures including technical, clinical and patient-oriented measures. The International Classification of Functioning, Disability and Health (ICF) as a common reference framework for functioning may contribute to improved outcome research. The objective of this paper is to provide an updated version of the linking rules published in 2002 and illustrate how these rules are applied to link technical and clinical measures, health-status measures and interventions to the ICF. RESULTS: Three specific linking rules have been established to link health-status measures to the ICF and one specific linking rule has been created to link technical and clinical measures and interventions. A total of 8 linking rules have been established for use with all different outcome measures and with interventions. CONCLUSION: The newly updated linking rules will allow researchers systematically to link and compare meaningful concepts contained in them. This should prove extremely useful in selecting the most appropriate outcome measures among a number of candidate measures for the applied interventions. Further possible applications are the operationalization of concrete ICF categories using specific measures or the creation of ICF category-based item bankings.     

Mutations in the calcium-related gene IL1RAPL1 are associated with autism

In a systematic sequencing screen of synaptic genes on the X chromosome, we have identified an autistic female without mental retardation (MR) who carries a de novo frameshift Ile367SerfsX6 mutation in Interleukin-1 Receptor Accessory Protein-Like 1 (IL1RAPL1), a gene implicated in calcium-regulated vesicle release and dendrite differentiation. We showed that the function of the resulting truncated IL1RAPL1 protein is severely altered in hippocampal neurons, by measuring its effect on neurite outgrowth activity. We also sequenced the coding region of the close related member IL1RAPL2 and of NCS-1/FREQ, which physically interacts with IL1RAPL1, in a cohort of subjects with autism. The screening failed to identify non-synonymous variant in IL1RAPL2, whereas a rare missense (R102Q) in NCS-1/FREQ was identified in one autistic patient. Furthermore, we identified by comparative genomic hybridization a large intragenic deletion of exons 3-7 of IL1RAPL1 in three brothers with autism and/or MR. This deletion causes a frameshift and the introduction of a premature stop codon, Ala28GlufsX15, at the very beginning of the protein. All together, our results indicate that mutations in IL1RAPL1 cause a spectrum of neurological impairments ranging from MR to high functioning autism.     

Teaching systems-based practice to residents by using independent study projects.

The changing health care marketplace requires new graduates to be familiar with complex health systems. Since 1999 the Oregon Health & Science University internal medicine residency program has offered a seminar-based health systems curriculum, but residents lacked an opportunity to actively apply learned concepts. To achieve this goal, the authors developed a second curricular component, the Health Systems Independent Study Project (HSISP). The HSISP is a self-directed assessment of a health care system or delivery issue residents complete in their third year. The curriculum was implemented in 2001 with goals of gaining a focused understanding of a health systems concept and building related skills. Residents present their study projects to all curriculum participants. Topics addressed so far include adherence to coronary artery disease guidelines in a defined population, screening strategies for lung cancer, resident burnout, and many others. Residents have found that these projects enhance their systems knowledge, help them link systems-based-practice concepts to clinical practice, and foster opportunities for networking and early career development.     

Losing culture on the way to competence: the use and misuse of culture in medical education.

Most cultural competence programs are based on traditional models of cross-cultural education that were motivated primarily by the desire to alleviate barriers to effective health care for immigrants, refugees, and others on the sociocultural margin. The main driver of renewed interest in cultural competence in the health professions has been the call to eliminate racial and ethnic disparities in the quality of health care. This mismatch between the motivation behind the design of cross-cultural education programs and the motivation behind their current application creates significant problems. First, in trying to define cultural boundaries or norms, programs may inadvertently reinforce racial and ethnic biases and stereotypes while doing little to clarify the actual complex sociocultural contexts in which patients live. Second, in attempting to address racial and ethnic disparities through cultural competence training, educators too often conflate these distinct concepts. To make this argument, the authors first discuss the relevance of culture to health and health care generally, and to disparities in particular. They then examine the concept of culture, paying particular attention to how it has been used (and misused) in cultural competence training. Finally, they discuss the implications of these ideas for health professions education.     

Epistaxis Due to Leech Infestation in Nose: A Report of Six Cases and Review of Literature

The aim of this study is to report unusual cause of epistaxis due to leech infestation in nose in hilly area and its management. The study was carried out for a period of 4 years (2008–2012) in a secondary level hospital in hilly area of Darjeeling, West Bengal, India with data collected from the OPD and Emergency register of the patients. This retrospective case series consisted of six cases. All the cases presented with unilateral recurrent epistaxis and foreign body nose. Anterior rhinoscopy revealed fleshy greenish brown mobile mass inside the nasal cavity which was removed by forceps. The animate foreign body was identified as leech in all the cases. To conclude, in hilly areas leech infestation can present as animate foreign body in nose and it should be considered as important cause of epistaxis.
