Early blood exchange transfusion in malignant pertussis: A case report.

OBJECTIVE:: To report early blood exchange transfusion in malignant pertussis and a favorable clinical outcome. SETTING:: A pediatric intensive care unit in a tertiary hospital in Geneva, Switzerland. DESIGN:: A descriptive case report. PATIENT:: An 8-wk-old girl was diagnosed with malignant pertussis (extreme leukocytosis, seizures, pneumonia, and secondary severe hypoxic respiratory failure associated with pulmonary hypertension). After administration of a one-volume blood exchange transfusion, a rapid decrease in white blood cell count (from 119,000/mm to 36,500/mm) was observed and followed by clinical improvement and favorable outcome despite the initial presence of all described risk factors associated with a high mortality. CONCLUSION:: The use of exchange blood transfusion early in the course of the disease might help to prevent a fatal outcome of malignant pertussis.

Les fluides de coupes : état des connaissances sur les usages, les expositions et les pratiques de gestion en France : rapport d'étude

Les fluides de coupe sont principalement utilisés pour leurs propriétés lubrifiantes et/ou pour leur qualité de refroidissement des pièces en métallurgie. Ils sont utilisés pour faciliter l'opération d'usinage et contribue à améliorer la durée de vie de l'outil utilisé. Ils permettent d'éloigner les copeaux de la zone de coupe, ce qui contribue à l'obtention d'un état de surface de qualité, et de refroidir le copeau et la pièce usinée afin de contribuer à la précision dimensionnelle de la pièce finie. Les usages des fluides de coupe sont en évolution depuis les années 2000. Il y a environ 15-30 ans, seules les huiles entières étaient utilisées. Aujourd'hui, l'utilisation des huiles varie selon le type d'application mais il est à noter toutefois que l'usage des huiles entières est en pleine décroissance depuis 2001, contrairement à celui des fluides aqueux (émulsions) en pleine expansion. Les fluides de coupe exposeraient selon l'étude SUMER plus de 1 million de travailleurs. Il existe deux grands secteurs principaux utilisateurs de ces fluides : le travail des métaux (qui expose selon l'INRS le plus grand nombre de salariés) et l'automobile (plus grand secteur utilisateur selon la CSNIL, Chambre Syndical Nationale de l'Industrie des Lubrifiants). De nombreux éléments existent autour de la prévention des risques liés à l'utilisation des fluides de coupe mais comme le rappelait l'INRS dans son rapport publié en 2002, la plupart des méthodes de prévention, collectives ou individuelles, bien que déjà connues, ne sont pas toujours appliquées, et notamment dans les petites entreprises. De plus les moyens de surveillance, bien que largement détaillés dans de nombreux guides, sont rarement mis en oeuvre. Néanmoins, des substances dangereuses peuvent se retrouver soit au sein de la formulation des fluides de coupe (comme certains additifs, biocides..), soit se former au cours du stockage (comme c'est le cas de pour la NDELA, N-nitroso diéthanolamine). Certaines substances ont déjà vu leur usage en tant que biocide être interdit en France, tel que le formaldéhyde ou encore l'acide borique. Des solutions de substitution existent déjà, telles que la micro-lubrification ou l'usinage à sec. Mais la mise en place ou la recherche de substituts s'accompagne souvent de difficultés en ce qui concerne l'adaptation du processus industriel. La mise en oeuvre des collaborations avec les fournisseurs doit donc être fortement encouragée. Enfin, il existe des zones d'ombre concernant les risques associés au développement microbiologique intervenant lors du vieillissement des fluides. L'utilisation grandissante de ces fluides de type aqueux est en lien avec ces problèmes de contamination microbienne des fluides ainsi que les pathologies respiratoires qui semblent y être associées. Cependant l'absence de référentiel exclut toute interprétation des résultats relatifs à ces agents microbiologiques retrouvés à la fois dans les fluides et les aérosols. Conclusions : En raison de la complexité de la formulation des fluides de coupe, il n'existe pas aujourd'hui de méthode de mesure fiable pour évaluer l'exposition à ces produits. Ainsi la mise en place d'une évaluation quantitative des risques sanitaires complète semble prématurée voire impossible. Il apparaît cependant nécessaire d'aller plus loin en matière de prévention : - une valeur limite pourrait être imposée concernant les quantités en amines secondaires précurseurs de nitrosamines, telle que développée dans le modèle allemand, le respect de cette réglementation allemande est déjà un argument mis en place par certains fournisseurs français ; - La micro-lubrification et la recherche de substitution doivent être encouragées ; - L'élaboration d'un référentiel microbiologique qui puisse tenir compte de la qualité des fluides et de la protection des travailleurs devrait être soutenue.

Neuronal calcium channel mutation in a patient with congenital ataxia and attacks of hemiplegic migraine with cerebral edema

Background: Familial Hemiplegic Migraine (FHM), characterized by a prolonged unilateral hemiparesis, mainly results from mutations in the alpha-1a subunit of the calcium channel gene CACNA1A that can also cause two other dominantly inherited neurological disorders, Episodic Ataxia type 2 (EA2, with sometimes migrainous headaches) and Spinocerebellar Ataxia type 6 (SCA6, late-onset and progressive). A same mutation can have different clinical expression in a family (hemiplegic migraine, migraine-coma, cerebellar ataxia). CACNA1A mutations in FHM are usually missense, leading to gain-of-function, while truncating mutations leading to loss-of-function are usually associated with EA2. Case report: This 9-year-old girl was seen as a baby for hypotonia and transient vertical nystagmus. Her first brain MRI was normal. She evolved as a congenital ataxia, but since the age of two, she had attacks of coma, hemiparesis (either side), partial seizures, dystonic movements and fever. Attacks were initially triggered by minor head bumps, subsequently spontaneous. Brain MRIs in the acute stage always showed transient unilateral hemisphere swelling. Follow-up images revealed atrophic lesions in the temporo-occipital regions and cerebellar atrophy. A prophylactic trial with flunarizine was ineffective. Acetazolamide was recently introduced. Methods: Since our patient shared features of both FHM and EA2, we studied the CACNA1A gene by direct sequencing in the patient's and parents' DNA. Results: We identified an unreported de novo heterozygous deletion of three base pairs (c.4503_4505delCTT) predicting the deletion of one amino acid (p.Phe1502del). The CACNA1A protein contains 4 domains, each formed by six transmembrane segments. The deletion is located in a highly conserved region in segment 6 (S6) of the third domain. Mutations in S6 segments of calcium channels change single-channel conductance and channel selectivity, most resulting in loss-of-function. Outlook: In vitro expression studies of the identified mutation are underway, aiming at understanding its functional consequences and finding an efficient treatment.

Isolated disturbance of written language-acquisition as an initial symptom of epileptic aphasia in a 7-year-old child - a 3-year follow-up-study

A 7-year-old right-handed girl developed partial complex seizures with a left-sided onset. A brief period of post-ictal aphasia of the conduction type was documented before seizure control and complete normalization of oral language were obtained. We also found that she had a history of previous unexplained difficulty with written language acquisition that had occurred prior to the clinically recognized epilepsy and a subsequent loss of this ability. This rapidly improved with control of the epilepsy. The evolution of written language were been followed for 3 years, and continued improvement has occurred with fluctuations related to her epilepsy. This observation adds support to the growing body of data indicating that specific cognitive disturbances can be due to epilepsy in young children. It shows the vulnerability of skills which are in a period of active development, and the possibility that oral/written language can be differentially involved by cerebral dysfunction in the young child.

Atypical Kawasaki disease with peripheral gangrene and myocardial infarction: therapeutic implications.

We describe a 2-month-old girl with atypical Kawasaki disease (KD) complicated by peripheral gangrene and myocardial infarction. Peripheral ischaemia leading to gangrene is a rare but serious complication of KD in infants younger than 7 months of age. Treatment has been targeted at reducing arterial inflammation, arteriospasm and thrombosis. We report the first patient with incomplete KD and peripheral ischaemia in whom therapy with prostaglandin E1 (PGE1) as vasodilating and antithrombotic agent appeared successful, restoring hand and foot perfusion without significant long-term sequelae. However, PGE1 could have supported development of myocardial infarction by shunting blood away from ischaemic areas distal to a giant coronary artery aneurysm with beginning thrombosis. CONCLUSION. Atypical KD with peripheral gangrene appears to react favourably to treatment with PGE1, but needs careful monitoring to detect early signs of cardiac ischaemia.

Color sensation in figurative painting

The figurative painter accesses very complex levels of knowledge. To produce a painting requires, first, a deep analysis of the image of the reality and, afterwards, the study of the reconstruction of this reality. This is not about a process of copying, but a process of the comprehension of the concepts that appear in the representation. The drawing guides us in the process of the production of the surface and in the distribution of the colours that, after all, are the data with which the vision mechanism builds the visual reality. Knowing the colour and its behaviour have always been a requirement for the figurative painter. From that knowledge we can draw wider conclusions.
