    Recent estimates have provided unprecedented numbers of orphans, and vulnerable children, either brought about because of the HIV/AIDS epidemic, or carriers themselves of HIV infections, a relentless growth which has precipitated a multifaceted care burden, that will too, grow for the next twenty years. This report records the proceedings of the Conference"Orphans and Other Vulnerable Children", which sought to promote awareness of the extent of this crisis, and, to probe the role of social protection in implementing a balanced response. The social protection framework for working with orphans, and vulnerable children shaped the conference agenda. Provision of appropriate risk management instruments is crucial for lasting poverty reduction, while programs to reduce the vulnerability of orphans, and other children, should play an integral role in any national development strategy, in the context of the HIV/AIDS epidemic. Building community capacity will constitute the centerpiece of any feasible response. Within a realistic framework, programs must spread, and scale up, to address the vast, and growing need.Street Children,Youth and Governance,Health Monitoring&Evaluation,Children and Youth,Primary Education

    Objectives The aim of this study was to evaluate the development of impaired median nerve function in relation to hand-intensive seasonal work. We hypothesized that at end-season, median nerve conduction would be impaired and then recover within weeks. Methods Using nerve conduction studies (NCS), we examined median nerve conduction before, during, and after engaging in 22 days of mink skinning. For a subgroup, we used goniometry and surface electromyography to characterize occupational mechanical exposures. Questionnaire information on symptoms, disability, and lifestyle factors was obtained. Results The study comprised 11 male mink skinners with normal median nerve conduction at pre-season (mean age 35.7 years, mean number of seasons with skinning 8.9 years). Mink skinning was characterized by a median angle of wrist flexion/extension of 16º extension, a median velocity of wrist flexion/extension of 22 °/s, and force exertions of 11% of maximal voluntary electrical activity. At end-season, mean distal motor latency (DML) had increased 0.41 ms (P<0.001), mean sensory nerve conduction velocity (SNCV) digit 2 had decreased 6.3 m/s (P=0.004), and mean SNCV digit 3 had decreased 6.2 m/s (P=0.01); 9 mink skinners had decreases in nerve conduction, 5 fulfilled electrodiagnostic criteria and 4 fulfilled electrodiagnostic and clinical criteria (a positive Katz hand diagram) for carpal tunnel syndrome (CTS). Three to six weeks post-season, the changes had reverted to normal. Symptom and disability scores showed corresponding changes. Conclusions In this natural experiment, impaired median nerve conduction developed during 22 days of repetitive industrial work with moderate wrist postures and limited force exertion. Recovery occurred within 3–6 weeks post-season

    International audienceOBJECTIVE: To evaluate sensory nerve conduction studies in ALS in a prospective multicentre study involving 7 neurophysiologists from 6 European countries. METHODS: Bilateral sural potentials were obtained in 35 ALS patients and 35 age-matched controls according to a standardised examination protocol using antidromic surface technique. The recordings from the right sural nerve of the controls were used for reference values. A reduction from the mean of controls greater than 2 SDs was considered abnormal. RESULTS: Reduced sensory nerve action potential (SNAP) amplitude or reduced conduction velocity (CV), or both, was found in 6 ALS patients (17%). Decrease in CV was the most frequent finding, and was observed in 8 nerves from 5 patients. Reduced SNAP amplitude was found in 2 nerves from 2 patients. All changes were minor ranging from -2.1 to -3.2 SDs. CONCLUSIONS: This is the first standardised multicentre study on sensory potentials in ALS. It confirms that although normal sensory findings should be expected in the majority of ALS patients, minor abnormalities are not uncommon. SIGNIFICANCE: Mild sensory abnormalities do not necessarily exclude a diagnosis of ALS

    Influence of medical audit on electrodiagnostic evaluation of polyneuropathy. A multicentre study.

    International audienceOBJECTIVE: Since 1992, 7 European neurophysiologists have participated in the ESTEEM project concerned with improvements in electrodiagnostic medicine. This study assesses whether the collaboration that includes peer review medical audit has influenced the involved physicians' electrodiagnostic criteria for polyneuropathy (PNP) diagnosing and classification. METHODS: Two sets of each physician's PNP examinations performed early and late in the study were examined for changes in (1) number of studies with abnormal electrophysiological findings required for diagnosing PNP, and (2) agreement between the classifications given by the individual physicians and the peer review group. RESULTS: The average number of abnormal motor nerve segments per patient increased from 4.6 to 6.4 during the study. Although most individual changes were minor, the second set of examinations showed an increased homogeneity among the physicians in the number of abnormal motor nerve segments and abnormal F wave studies, and a tendency towards increased homogeneity in the number of abnormal sensory nerve segments. There was also an increased agreement on pathophysiological PNP classification in the second set of examinations compared to the first set. CONCLUSIONS: The participation in the ESTEEM project seems to have impacted the physicians' clinical routine, possibly as they have accustomed themselves to apply criteria more strictly. SIGNIFICANCE: This study support that international collaboration is a useful step towards improvements in electrodiagnostic medicine
