[Monotherapy using amoxicillin/clavulanic acid as treatment of first choice in community-acquired lung abscess. Apropos of 57 cases]. / Monothérapie par amoxicilline/acide clavulanique (AM-AC) en traitement de première intention dans les abcès pulmonaires communautaires. A propos de 57 cas.

In a multicentre open prospective trial the effectiveness of AM-CA as first-line treatment of community-acquired lung abscess was evaluated in immunocompetent adult patients. AM-CA was administered intravenously in doses of 4 g/day for at least 7 days, then orally in doses of 2 g/day for at least 14 days. Radio-clinical and laboratory evaluations were made during treatment, and 30 and 60 days after it was discontinued. The results of this trial concerned 57 patients (48 men, 9 women; mean age 52 years). The facilitating factors were those usually found in lung abscess. Twenty-seven patients had previously received an antibiotic treatment which had failed. The clinical picture, built up gradually in 42/37 patients, consisted of infectious syndrome (52 cases), altered general condition (39 cases), purulent expectoration (47 cases), sometimes foetid (10 cases), and thoracic clinical abnormalities (57 cases. X-ray films of the chest showed round abscess images (44 cases) or looked like necrotizing pneumonia (13 cases) with pleural reaction (8 cases). Protecting bacteriological sampling by BFW brushing and transtracheal or transparietal sample collecting was performed in 41 of the 57 patients. The pathogens, isolated in 31 cases, were: S. pneumoniae 5; Streptococcus spp. 12; Staph. aureus 4; H. influenzae 7; Enterobacteriaceae 6; anaerobes 7. These organisms were associated in 8 cases. With the exception of Enterobacter cloacae, all were sensitive to AM-CA in-vitro. The outcome was satisfactory in 52 patients.

[Visceral leishmaniasis associated with Hodgkin's disease: diagnostic difficulties]. / Leishmaniose viscérale associée à une maladie de Hodgkin: difficultés diagnostiques.

A case of Hodgkin's disease associated from the start with visceral leishmaniasis in the absence of antitumoral treatment shows that leishmaniasis is a severe opportunistic infection in endemic areas and can be masked by the tumoral syndrome of an underlying pathology. Conversely, patients with visceral leishmaniasis must be investigated for a cause of immunosuppression with, in particular, biopsy of accessible lymph nodes. The exceptionally favourable course of this particular case deserved to be high-lighted.

[Digitalis poisoning and severe respiratory insufficiency]. / Intoxication digitalique et insuffisance respiratoire grave.

After seeing 9 cases of digitalis intoxication in patients with acute respiratory decompensation of chronic respiratory failure in one year in an intensive care unit, the authors decided to review the literature on the subject. They set out to: --determine the clinical, laboratory and electrical features of digitalis intoxication in patients with chronic respiratory failure, accounting for the frequency of supraventricular arrhythmias; --evaluate the frequency of this intoxication (20% in this study), introducing a definite risk factor, given the poor haemodynamic effectiveness of digitaloids in this indication; --establish a therapeutic management based on the use of anti-arrhythmics and especially on the prevention of predisposing factors (hypoxaemia--functional renal failure and abuse of diuretics).
