Increasing prehospital emergency medical service interventions for nursing home residents.

QUESTION: In the ageing European population, the proportion of interventions by the emergency medical services (EMS) for elderly patients is increasing, but little is known about the recent trend of EMS interventions in nursing homes. The aim of this analysis was to describe the evolution of the incidence of requests for prehospital EMS interventions for nursing home residents aged 65 years and over between 2004 and 2013. METHODS: A prospective population-based register of routinely collected data for each EMS intervention in the Canton of Vaud. Linear time trends of incidence of requests to the EMS in nursing homes were calculated and stratified by age categories. RESULTS: The number of ambulance interventions in nursing homes for people aged 65 years and over (65+) increased by 68.9% (1124‒1898) between 2004 and 2013. A significant linear increase of the annual incidence of requests to EMS per 1,000 nursing home residents was found for people aged 65-79 (10.2, 95% confidence interval [CI] 6.2-14.2), 80-89 (16.5, 95% CI 14.0-19.0) and over 90 (12.1, 95% CI 5.8-18.4). EMS interventions in nursing home residents who required an emergency physician increased during the same period by 205.6% (from 106 to 324), representing an increase from 2% to 7% of all emergency physician interventions in the Canton. CONCLUSIONS: Our results confirmed an important increase in the incidence of EMS interventions in nursing homes during the last decade, far exceeding the actual increase of the nursing home population during the same period. This evolution represents an important opportunity to reconsider the EMS missions in the context of an ageing society

Axonal Regeneration and Neuronal Function Are Preserved in Motor Neurons Lacking ß-Actin In Vivo

The proper localization of ß-actin mRNA and protein is essential for growth cone guidance and axon elongation in cultured neurons. In addition, decreased levels of ß-actin mRNA and protein have been identified in the growth cones of motor neurons cultured from a mouse model of Spinal Muscular Atrophy (SMA), suggesting that ß-actin loss-of-function at growth cones or pre-synaptic nerve terminals could contribute to the pathogenesis of this disease. However, the role of ß-actin in motor neurons in vivo and its potential relevance to disease has yet to be examined. We therefore generated motor neuron specific ß-actin knock-out mice (Actb-MNsKO) to investigate the function of ß-actin in motor neurons in vivo. Surprisingly, ß-actin was not required for motor neuron viability or neuromuscular junction maintenance. Skeletal muscle from Actb-MNsKO mice showed no histological indication of denervation and did not significantly differ from controls in several measurements of physiologic function. Finally, motor axon regeneration was unimpaired in Actb-MNsKO mice, suggesting that ß-actin is not required for motor neuron function or regeneration in vivo

Significance of persisting IgM anti‐HBc antibodies in hepatitis B virus infection

IgG and IgM antibodies to the core antigen of hepatitis B virus (HBV) were measured in 136 patients who developed acute HBV hepatitis and who were followed prospectively. After acute hepatitis all the patients developed transiently IgM anti‐HBc lasting for two to five months. In contrast, IgM anti‐HBc persisted 8 and 9 months in two patients who developed persistent hepatitis and were continuously detected for two years in nine patients who developed aggressive hepatitis. The results presented suggest that the determination of IgM anti‐HBc might be useful to predict the outcome of chronic hepatitis B infection. Copyright © 1981 Wiley‐Liss, Inc.

Tuberculosis in children: a 13-year follow up of 1714 patients in a Belgian home care centre.

From May 1970 to September 1983, 1714 children with different forms of primary tuberculosis were referred to the paediatric home care centre (Enfants soignés au Foyer, E.S.F.) of the Brussels University Hospital St.-Pierre. They were subdivided in five groups: asymptomatic (33%), symptomatic (28%), dubious tuberculous infections (35%), high-risk contacts (3%) and unestablished diagnosis (1%). They were aged from 10 days to 19 years, and 82% of them were migrants of low socio-economic level. Fifty percent of the symptomatic infections, mainly pulmonary, appeared in children under 3 years of age. An adult source of contamination was identified in 33% of the cases (48% of the symptomatic children). Diagnosis was based on tuberculin screening with a 2IU intradermal test. Gastric aspirates yielded Mycobacterium tuberculosis in 15% of our patients, 11% of them showing resistance to one or more tuberculostatic drugs. Treatment was given to 1359 patients with excellent results. Therapy was shortened during the last 2 years of the study from 12 to 6 months for the asymptomatic patients and from 12 to 9 months for the symptomatic infections. Few complications were observed. Tuberculosis remains a serious cause of morbidity particularly in migrant children. Correct diagnosis and treatment of the disease is very important.Journal Articleinfo:eu-repo/semantics/publishe

Hydroxyurea for treatment of severe sickle cell anemia: a pediatric clinical trial.

Hydroxyurea (HU) enhances the synthesis of fetal hemoglobin (HbF) and can improve the clinical course of some adult patients with sickle cell anemia (SCA). In a randomized trial, we studied the biologic effects and the clinical benefit of HU in children and young adults with severe SCA. Twenty-five patients (median age, 9 years) were randomized to receive either HU (at the initial dosage of 20 mg/kg/d) or a placebo for 6 months and were then switched to the other arm for the next 6 months. Among the 22 evaluable patients (median age, 8 years), significant increases in HbF and mean corpuscular volume occurred during the HU treatment period. The white blood cell and reticulocytes counts decreased significantly, but these changes were not clinically relevant. Sixteen of 22 patients (73%) experienced a complete disappearance of events requiring hospitalization. The number of days of hospitalization as well as the number of hospitalizations for patients on HU, as compared with those for the patients receiving placebo, were significantly reduced. We conclude that treatment with HU in children and young adults is feasible, well-tolerated, and improves the clinical course of SCA. The long-term effects of HU require further investigation

Growth failure, encephalopathy, and endocrine dysfunctions in two siblings, one with 5-oxoprolinase deficiency

Two female siblings, born to consanguineous parents, presented with a similar phenotype characterized by severe growth and developmental failure, dysmorphic features, thyroid and gonadal dysfunction, autistic traits and hand stereotypes resembling Rett syndrome. In the elder patient, analysis of urinary organic acids disclosed a very high excretion of 5-oxoproline (4.2 to 8.1 mol/mol creatinine) and enzyme assays of leucocyte extracts revealed a profound deficiency of 5-oxoprolinase. However, normal urinary organic acid profiles were found in the younger child. In view of their distinct dysmorphic features and severe growth deficiency, these siblings cannot be considered as Rett Syndrome variants. The Dubowitz and carbohydrate-deficient glycoprotein syndromes were also excluded clinically and biochemically respectively. We conclude that these patients suffer from a hitherto undescribed autosomal recessive disorder, unrelated to the 5-oxoprolinase deficiency of the elder sib. Conclusion: The present findings give evidence that 5-oxoprolinase deficiency is not associated with a distinct morbid phenotype.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
