La ventilation non invasive dans l'insuffisance respiratoire aiguë : de la broncho-pneumonie chronique obstructive au syndrome de détresse respiratoire aiguë

RESUME : L'application d'une ventilation non-invasive (VNI) à pression positive chez des patients avec une insuffisance respiratoire aiguë hypoxémique non liée à une broncho-pneumopathie chronique obstructive (BPCO), reste controversée malgré les résultats encourageants apparus dans de récentes études. Ce travail de thèse est composé d'une introduction qui comprend un historique de la VNI et une revue de ces applications principales dans l'insuffisance respiratoire aiguë avec, en particulier, une analyse des études cliniques principales concernant son utilisation dans l'exacerbation de la BPCO, dans l'asthme aigu sévère, dans les syndromes restrictifs et dans l'insuffisance respiratoire aiguë hypoxémique. La première partie aborde également les aspects pratiques de l'utilisation de la VNI, avec une description de l'équipement et des techniques utilisées. Ce travail de thèse a ensuite pour but d'analyser dans une étude personnelle l'application d'une VNI à pression positive chez des patients avec une insuffisance respiratoire aiguë hypoxémique non liée à une BPCO. Il s'agit d'une étude prospective et observationnelle, dans laquelle nous avons voulu analyser l'efficacité de la VNI chez un groupe de patients sélectionnés et coopérants, stables du point de vue hémodynamique, présentant un syndrome de détresse respiratoire aiguë (SDRA) primaire (atteinte pulmonaire directe). Les échanges gazeux, le taux d'intubation, la mortalité et la durée de séjour dans l'unité de soins intensifs ont été enregistrés. Dans notre travail, la VNI a été appliquée de manière prospective à 12 patients, stables du point de vue hémodynamique, présentant les critères diagnostiques pour un SDRA primaire (SDRAP) et une indication pour une ventilation mécanique classique. Leur évolution a été comparée avec celle d'un groupe contrôle de 12 patients avec SDRAP. et précédemment traités dans la même unité de soins intensifs, ayant des caractéristiques similaires à l'admission : âge, score SAPS II, rapport Pa02/Fi02 et valeurs de pH . Un échec de la VNI fut observé chez 4 patients (33%), tous bactériémiques et nécessitant une intubation endotrachéale. Un facteur prédictif négatif. Les patients traités avec succès ont présenté un temps cumulatif de ventilation (p=0.001) et une durée de séjour aux soins intensifs (p=0.004) inférieure à ceux du groupe contrôle. Pendant la première période d'observation de la ventilation, l'oxygénation après 60 minutes s'est améliorée de manière plus importante dans le groupe VNI par rapport au groupe contrôle (PaO2/FiO2 : 146 +/- 52 mmHg vs. 109 +/- 34 mmHg ; p=0.05). Le taux de mortalité globale aux soins intensifs ne fut pas différent entre le groupe VNI et le groupe de patients intubés. Le taux de complications graves fut plus élevé chez les patients du groupe contrôle. Nos résultats suggèrent que chez des patients stables et coopérants, avec une pneumonie étendue, sans bactériémie à l'admission et remplissant les critères diagnostiques d'un SDRAp, la VNI représente une alternative valable à l'intubation endotrachéale.

Point Mutations in the Monocarboxylate Transporter SLC16A12 Lead to Juvenile and Age-Related Cataract

Purpose: Previously we reported on a premature termination mutation in SLC16A12 that leads to dominant juvenile cataract and renal glucosuria. To assess the mutation rate and genotype-phenotype correlations of SLC16A12 in juvenile or age-related forms of cataract, we performed a mutation screen in cataract patients. Methods: Clinical data of approximately 660 patients were collected, genomic DNA was isolated and analyzed. Exons 3 to 8 including flanking intron sequences of SLC16A12 were PCR amplified and DNA sequence was determined. Selected mutations were tested by cell culture assays, in silico analysis and RT-PCR. Results: We found sequence alterations at a rate of approximately 1/75 patients. None of them was found in 360 control alleles. Alterations affect splice site and regulatory region but most mutations caused an amino acid substitution. The majority of the coding region mutations maps to trans-membrane domains. One mutation located to the 5'UTR. It affects translational efficiency of SLC16A12. In addition, we identified a cataract-predisposing SNP in the non-coding region that causes allele-specific splicing of the 5'UTR region. Conclusions: Altered translational efficiency of the solute carrier SLC16A12 and its allele-specific splicing strongly support a model of challenged homeostasis to cause various forms of cataract. In addition, the pathogenic property of the here reported sequence alterations is supported by the lack of known sequence variations within the coding region of SLC16A12. Due to the relatively high mutation rate, we suggest to include SLC16A12 in diagnostic cataract screening. Generally, our data recommend the assessment of regulatory sequences for diagnostic purposes.

Delirium auf der Intensivstation [Delirium in the intensive care unit.]

The prevalence of delirium in the Intensive Care Unit (ICU) is reported to vary from 20 to 80 %. Delirium in the ICU is not only a frightening experience for the patient and his or her family, it is also a challenge for the nurses and physicians taking care of the patient. Furthermore, it is also associated with worse outcome, prolonged hospitalisation, increased costs, long-term cognitive impairment and higher mortality rates. Thus, strategies to prevent ICU-delirium in addition to the early diagnosis and treatment of delirium are important. The pathophysiology of delirium is still incompletely understood, but numerous risk factors for the development of delirium have been identified in ICU-patients, among which are potentially modifiable factors such as metabolic disturbances, hypotension, anaemia, fever and infection. Key factors are the prevention and management of common risk factors, including avoiding overzealous sedation and analgesia and creating an environment that enhances reintegration. Once delirium is diagnosed, treatment consists of the use of typical and atypical antipsychotics. Haloperidol is still the drug of choice for the treatment of delirium and can be given intravenously in incremental doses of 1 to 2 to 5 (to 10) mg every 15 - 20 minutes.

Impact of infection on the prognosis of critically ill cirrhotic patients: results from a large worldwide study.

BACKGROUND: Infections are a leading cause of death in patients with advanced cirrhosis, but there are relatively few data on the epidemiology of infection in intensive care unit (ICU) patients with cirrhosis. AIMS: We used data from the Extended Prevalence of Infection in Intensive Care (EPIC) II 1-day point-prevalence study to better define the characteristics of infection in these patients. METHODS: We compared characteristics, including occurrence and types of infections in non-cirrhotic and cirrhotic patients who had not undergone liver transplantation. RESULTS: The EPIC II database includes 13,796 adult patients from 1265 ICUs: 410 of the patients had cirrhosis. The prevalence of infection was higher in cirrhotic than in non-cirrhotic patients (59 vs. 51%, P < 0.01). The lungs were the most common site of infection in all patients, but abdominal infections were more common in cirrhotic than in non-cirrhotic patients (30 vs. 19%, P < 0.01). Infected cirrhotic patients more often had Gram-positive (56 vs. 47%, P < 0.05) isolates than did infected non-cirrhotic patients. Methicillin-resistant Staphylococcus aureus (MRSA) was more frequent in cirrhotic patients. The hospital mortality rate of cirrhotic patients was 42%, compared to 24% in the non-cirrhotic population (P < 0.001). Severe sepsis and septic shock were associated with higher in-hospital mortality rates in cirrhotic than in non-cirrhotic patients (41% and 71% vs. 30% and 49%, respectively, P < 0.05). CONCLUSIONS: Infection is more common in cirrhotic than in non-cirrhotic ICU patients and more commonly caused by Gram-positive organisms, including MRSA. Infection in patients with cirrhosis was associated with higher mortality rates than in non-cirrhotic patients.

A quantum molecular similarity analysis of changes in molecular electron density caused by basis set flotation and electric field application

Quantum molecular similarity (QMS) techniques are used to assess the response of the electron density of various small molecules to application of a static, uniform electric field. Likewise, QMS is used to analyze the changes in electron density generated by the process of floating a basis set. The results obtained show an interrelation between the floating process, the optimum geometry, and the presence of an external field. Cases involving the Le Chatelier principle are discussed, and an insight on the changes of bond critical point properties, self-similarity values and density differences is performed
