We study the dynamics of a two-degree-of-freedom (DOF) nonlinear system consisting of a grounded linear oscillator coupled to a light mass by means of an essentially nonlinear (nonlinearizable) stiffness. We consider first the undamped system and perform a numerical study based on non-smooth transformations to determine its periodic solutions in a frequency-energy plot. It is found that there is a sequence of periodic solutions bifurcating or emanating from the main backbone curve of the plot. We then study analytically the periodic orbits of the undamped system using a complexification/averaging technique in order to determine the frequency contents of the various branches of solutions, and to understand the types of oscillation performed by the system at the different regimes of the motion. The transient responses of the weakly damped system are then examined, and numerical wavelet transforms are used to study the time evolutions of their harmonic components. We show that the structure of periodic orbits of the undamped system greatly influences the damped dynamics, as it causes complicated transitions between modes in the damped transient motion. In addition, there is the possibility of strong passive energy transfer (energy pumping) from the linear oscillator to the nonlinear attachment if certain periodic orbits of the undamped dynamics are excited by the initial conditions.

This report is concerned with a patient aged 76 with mild to moderate aortic stenosis and transient A-V block who was treated by stand-by intracardiac pacing. In spite of this, the patient continued to present syncopal attacks. It is demonstrated that these episodes were related to dramatic decreases of systolic blood pressure and cardiac output occurring whenever the right ventricle was paced. These hemodynamic alterations were secondary to the loss of atrial contribution to ventricular filling. They were suppressed by insertion of a sequential auriculoventricular pacemaker. [less ▲]

We are reporting the case of a 55-year-old man with stage II chronic lymphoid leukemia, complicated by Herpes zoster ophtalmicus with controlateral hemiplegia. This hemiplegia has been interpreted as the consequence of a granulomatous angiitis. Anti-viral drugs should be useful in the treatment of these cases. [less ▲]

Les complications gastro-intestinales du diabète peuvent toucher la totalité du tube digestif. Elles sont fréquentes et compliquent habituellement un diabète ancien et insulinodépendant. Elles sont souvent latentes, mises en évidence par des méthodes isotopiques ou manométriques, parfois invalidantes comme la gastroparésie, la diarrhée et l'incontinence fécale. L'atteinte digestive s'associe toujours à une atteinte nerveuse périphérique et fait partie des manifestations neurovégétatives du diabète. Les troubles digestifs participent à déséquilibrer le diabète et une gastroparésie devra systématiquement être recherchée devant des accidents hypoglycémiques répétés et inexpliqués. Le mécanisme physiopathologique est mal connu et le traitement de ces complications est souvent difficile et décevant. [less ▲]

Psychiatric complications are clearly associated with substance abuse. Psychopathological symptoms appear during intoxication or in patients suffering from substance-induced psychiatric disorders. However, the assessment of the psychiatric symptomatology is particularly challenging in patients who express clear difficulties to accept that the disorder is favoured by substance abuse. Psychotic reactions, major depression and anxiety disorders are the main psychiatric issues observed in addict patients. [less ▲]
