[Analytic study of electroretinograms of 280 patients treated with synthetic antimalarials]. / Etude analytique d'électrorétinogrammes (ERG) de 280 patients sous antipaludéens de synthèse (A.P.S.).

An analytic study of electroretinogramms (ERG) from 280 patients under antimalarial therapy has been made. The pratician has stopped treatment in 4.8% of the ERG. Among the investigated parameters, the only statistic difference is the cumulative doses.

[Oculomotor paralysis in disseminated lupus erythematosis]. / Paralysies oculomotrices dans le lupus érythémateux disséminé.

The inferior oblique isolated damage in the systemic lupus erythematosus is being described. The ocular palsies are few and exceptionally isolated. Few studies have been published on the damage topography which can relate to micro-infarcts, or focal vasculitis. The involvement is either central or peripheral. The diagnosis by NMR is more reliable than by TDM.

Bioenergetic and cardiovascular responses to exercise in residents at 2.850 m, with asymptomatic Chagas' disease.

Cardiovascular and energetic responses at rest, during 30 min of exercise (mechanical output: 125 watts) and for a subsequent recovery period of 5 min were compared in two groups, each comprising 21 residents at an altitude of 2.850 m. One group was in the asymptomatic phase of Chagas' disease with positive serological tests for T. cruzi, whereas the other was without Chagas' disease (negative serological tests). The two groups were similar as regards age, weight-for-height, blood parameters, nutritional status and heart and lung functions, including heart rate and frontal plane QRS axis determinations. At rest, they differed in that maximal and minimal arterial blood pressures were slightly but significantly lower in the group with Chagas' positive serological tests than in the controls. During exercise and recovery, the only differences between them and the controls were that their minimal diastolic arterial blood pressure was significantly lower. In absolute values, the rises in arterial pressure due to exercise were exactly the same in the two groups. Maximal O2 uptake was identical in both groups, as was exercise steady state VO2. These findings indicate that the asymptomatic subjects with Chagas' disease had a normal work capacity and were not affected by high altitude.
