Energy metabolism during the postexercise recovery in man.

In order to explore the magnitude and duration of the long-term residual effect of physical exercise, a mixed meal (55% CHO, 27% fat and 18% protein) was given to 10 young male volunteers on two occasions: after a 4-h resting period, and on the next day, 30 min after completion of a 3-h exercise at 50% VO2max. Energy expenditure and substrate utilization were determined by indirect calorimetry for 17 h after meal ingestion. The fuel mix oxidized after the meal was characterized by a greater contribution of lipid oxidation to total energy expenditure when the meal was ingested during the post-exercise period as compared with the meal ingested without previous exercise. During the night following the exercise, the stimulation of energy expenditure observed during the early recovery period gradually faded out. However, resting energy expenditure measured the next morning was significantly higher (+4.7%) than that measured without previous exercise. It is concluded that intense exercise stimulates both energy expenditure and lipid oxidation for a prolonged period.

A young man with a renal colic

We report the case of a 35-year-old man with no cardiovascular morbidity, presenting with acute flank pain, microscopic haematuria and normal blood pressure. Initially diagnosed as a ureteral colic, the patient was recovered 6 weeks later with severe hypertensive crisis. Further investigations revealed a massive renal infarction secondary to medial fibromuscular dysplasia (FMD). Several aspects of this presentation are intriguing. Renal infarcts are usually seen in older patients having cardiac problems and/or major atheromatous plaques. In addition, FMD is mainly observed in young females and rarely progresses to renal artery occlusion. Furthermore, in this case, FMD remained silent until the acute renal infarction occurred, despite a significant kidney size reduction at the time of diagnosis. Finally, the observation of a delayed hypertensive response to a major renovascular insult provides incentives to discuss possible pathophysiological mechanisms involved in renovascular hypertension.

Myéloradiculopathie chronique progressive chez un homme de 61 ans [Chronic progressive myeloradiculopathy in a 61-year-old man]

A painful worsening of known difficulties in walking led us to investigate a man who presented a spastic paraparesis. Radiological investigations had to be repeated three times before making a diagnosis of a right C6 spinal dural arteriovenous fistula after a 22-month follow-up. Knowing the mechanisms leading to spinal venous hypertension may explain the low yield of the early radiological investigations that should be repeated. The efficiency of the treatment depends on the severity of the presurgical neurologic manifestations.

Jour de rien : la nuit sans les dieux. Paul Valéry, la mer, le matin

(Résumé de l'ouvrage) Professeur émérite de la Faculté de théologie protestante de Montpellier, dont il a occupé la chaire de dogmatique de 1971 à 1998, André Gounelle incarne, pour des générations d'étudiants et de lecteurs, une certaine idée de la rigueur intellectuelle. Son attention profonde à la pensée des autres, la forme lumineusement classique de son discours, sa probité radicale et sans réserve dans l'exercice de la critique sont les fondements de la tâche qu'il s'est donnée (formuler les conditions d'un croire possible), de la quête qui l'occupe (dire et penser le Dieu vivant), du grand souci qui le caractérise (transmettre et faire partager l'Évangile). La diversité des contributions qui composent ce volume signale à la fois l'étendue des champs d'exploration et l'ampleur du retentissement des travaux d'André Gounelle. Ses études sur la pensée religieuse et philosophique de Blaise Pascal ou de Paul Tillich, ses dialogues avec les théologiens de la mort de Dieu ou du Process et, bien sûr, ses nombreuses monographies sur la dogmatique chrétienne d'hier et d'aujourd'hui rayonnent bien au-delà des frontières de l'hexagone et du protestantisme. En témoignent, à leur manière, les titres de Docteur honoris causa que lui ont conféré l'Université de Lausanne et l'Université Laval de Québec. Le volume jubilaire que voici a été offert à André Gounelle à l'occasion de son soixante-dixième anniversaire. C'est à l'ami et au maître que les trente-et-un auteurs de ces mélanges ont tenu à exprimer leur estime et leur reconnaissance.
