The concept of instability: a French perspective on the concept of ADHD.

Historical references to the emergence of the current concept of ADHD typically cite descriptions from medical textbooks by Weikard (1775) and Crichton (An inquiry into the nature and origin of mental derangement: Comprehending a concise system of the physiology and pathology of the human mind and a history of the passion and their affects. Cardell Jr and Davies, Londres, 1798) on attention disorders, poems of Hoffman on hyperactive and impulsive behaviors (Der Struwwelpeter. Frankfurt am Main, Literarische Anstalt, 1843), as well as the work of Still (Lancet 1:1008-1012, 1077-1082, 1163-1168, 1902a, Lancet 159(4102):1008-1013, 1902b, Lancet 159(4103):1077-1082, 1902c, Lancet 159(4104):1163-1168, 1902d) on impulsive behaviors and defective moral regulation of behavior. The notion of "instability" developed by French physicians between 1887 and 1910 is rarely mentioned and often ignored. Writings from this period show that in France, the emergence of the concept of ADHD according to modern terminology comes from the notion of "mental instability" introduced in the 1890s under the leadership of Désiré-Magloire Bourneville at the Hospital Bicêtre in Paris, based on his observations of children and adolescents who had been labeled "abnormal" and placed in medical and educational institutions. In the early twentieth century, elaborating on the observations of Bourneville, Jean Phillipe and Georges Paul-Boncour showed the presence of a subgroup of "unstable" children who suffered from a disease entity in its own right within the population of "abnormal" schoolchildren (the terminology of the time). This new pathological entity included symptoms of hyperactivity, impulsivity and inattention, corresponding to today's classic triad of ADHD symptoms. While noting the lack of behavioral inhibition, clinical descriptions of Bourneville, Philip and Paul-Boncour also considered the notion of "moral disorder" which at that time played an important role in psychopathology. This resulted in some degree of confusion between impulsive symptoms and major behavioral disturbances often associated with ADHD.

Swiss DVI at the tsunami disaster: expect the unexpected.

The conclusions reached while considering various aspects of the implemented strategy in the identification procedures in the wake of the tsunami disaster of December 26, 2004 are outlined. The lessons to be learned are discussed.

High one year mortality in adults with sickle cell disease and end-stage renal disease.

Adequate pre-dialysis care reduces mortality among end-stage renal disease (ESRD) patients. We tested the hypothesis that individuals with ESRD due to sickle cell disease (SCD-ESRD) receiving pre-ESRD care have lower mortality compared to individuals without pre-ESRD care. We examined the association between mortality and pre-ESRD care in incident SCD-ESRD patients who started haemodialysis between 1 June, 2005 and 31 May, 2009 using data provided by the Centers for Medicare and Medicaid Services (CMS). SCD-ESRD was reported for 410 (0·1%) of 442 017 patients. One year after starting dialysis, 108 (26·3%) patients with incident ESRD attributed to SCD died; the hazard ratio (HR) for mortality among patients with SCD-ESRD compared to those without SCD as the primary cause of renal failure was 2·80 (95% confidence interval [CI] 2·31-3·38). Patients with SCD-ESRD receiving pre-dialysis nephrology care had a lower death rate than those with SCD-ESRD who did not receive pre-dialysis nephrology care (HR = 0·67, 95% CI 0·45-0·99). The one-year mortality rate following an ESRD diagnosis was almost three times higher in individuals with SCD when compared to those without SCD but with ESRD and could be attenuated by pre-dialysis nephrology care.

Genetic heterogeneity of the Coppock-like cataract: a mutation in CRYBB2 on chromosome 22q11.2.

PURPOSE: To identify the genetic defect for the Coppock-like cataract (CCL) affecting a Swiss family, which defect was unlinked to the chromosome 2q33-35 CCL locus. METHODS: A large family was characterized for linkage analysis by slit lamp examination or by the review of drawings made before cataract extraction. The affection status was attributed before genotyping, and the genotyping was masked to the affection status. Two-point and multipoint linkage analyses were performed using the MLINK and the LINKMAP components of the LINKAGE program package (ver. 5.1), respectively. Mutational analysis of candidate genes was performed by a combination of direct cycle sequencing and an amplification refractory mutation system assay. RESULTS: Ten individuals were affected with the CCL phenotype. The disease was autosomal dominant and appeared to be fully penetrant. A new CCL locus was identified on chromosome 22q11.2 within a 11.67-cM interval (maximum lod score [Zmax] = 4.14; theta = 0). Mutational analysis of the CRYBB2 candidate gene identified a disease-causing mutation in exon 6. This sequence change was identical with that previously described to be associated with the cerulean cataract, a clinically distinct entity. CONCLUSIONS: The CCL phenotype is genetically heterogeneous with a second gene on chromosome 22q11.2, CRYBB2. The CCL and the cerulean cataract are two distinct clinical entities associated with the same genetic defect. This work provides evidence for a modifier factor that influences cataract formation and that remains to be identified.

Medio ambiente y producción primaria frente al área Pimentel - Chimbote

Se presentan en variaciones estacionales y se discuten las interrelaciones entre el medio ambiente y la productividad durante agosto de 1972 - junio 1973 en el área de 06° - 09°S, la cual es un importante centro de afloramiento. Este estudio forma parte de las investigaciones que se realizan en dicha área a través del proyecto OEA/ IMARPE. Las temperaturas en la superficie del mar se desarrollaron por encima del promedio hasta marzo de 1973, restableciéndose las condiciones oceanográficas en abril de ese año. En diciembre se observó un cambio brusco en las condiciones oceanográficas debido a la presencia de las aguas de la región ecuatorial las cuales avanzaron hasta Huarmey (10°S) en forma de una lengua costera con temperaturas de 23 - 25 °C, salinidades de 34.0 - 34.8‰, bajo contenido de nutrientes y pobre productividad, afectando la distribución y/o disponibilidad de la fauna marina. En la superficie del mar se halló la relación P: N: Si promedio de 1: 9.5: 8.3, lo cual hace pensar que los silicatos pueden llegar a ser limitantes en la producción fotosintética. La clorofila "a" lejos de la costa presentó concentraciones bajas y relativamente uniformes con la profundidad, con un promedio de 0.60 ug/L en la columna 0-25 m, mientras que cerca de la costa su distribución vertical fue irregular presentando también valores bajos con relación al promedio del área debido a los efectos del Fenómeno El Niño de 1972-73.

Evolução da Produtividade das Empresas em Cabo Verde no Período de 1997 a 2002

Neste estudo pretendeu-se analisar as mudanças na produtividade das empresas em Cabo Verde no período de 1997 a 2002. Os resultados do estudo indicam que houve melhorias significativas na produtividade empresarial e essa melhoria no desempenho foi determinado principalmente pelo progresso tecnológico. Entretanto, essa melhoria na produtividade não foi acompanhada por aumentos no numero de empresas e nem de empregos, podendo ser interpretado como uma evidencia da diminuição no investimento das empresas isto é, pode ser que as empresas estejam a optar por maior consumo em detrimento do investimento. É necessário maior intervenção do governo no sentido de dinamizar o surgimento de novas empresas e geração de emprego, assim como maior estimulo ao reinvestimento por parte das empresas existentes, enquanto que essa é uma condição necessária para reduzir os elevados índices de desemprego e colocar o país na rota de crescimento e desenvolvimento.
