[Surgical correction of the pectus excavatum and carinatum in the adult. Report of an unusual case of combination of the straight back and pectus excavatum].

Surgical correction of pectus excavatum et carinatum in a series of adult patients is described. The relationship between deformity of the anterior chest wall and cardiac, respiratory and digestive disturbances is assessed. The indications for surgical management are explained. Reference is also made to the satisfactory morphological and respiratory function results observed on follow-up. An unusual cases of pectus excavatum associated with straight back is separately described. Here again, successful surgical management was achieved, coupled with disappearance of functional disturbances and improvement of the heart picture.

In vivo assessment of mitochondrial functionality in human gastrocnemius muscle by 31P MRS. The role of pH in the evaluation of phosphocreatine and inorganic phosphate recoveries from exercise.

In this study we compared the kinetics of phosphocreatine (PCr) and P(i) recovery, and their dependency on cytosolic pH in 38 normal individuals. Spectra were acquired during rest, work and recovery. A time resolution of 10 s was used to obtain detailed information. The kinetics of PCr and P(i) recovery almost overlapped when the lowest value of cytosolic pH reached during recovery (termed the minimum pH) was < 6.95, while they were completely dissociated when the minimum pH was > 6.95. This result is interpreted as indirect in vivo evidence of the kinetic control exerted by ADP on mitochondrial oxidation. Our results represent a rationale for new experimental conditions to be used in clinical routine studies of pathologies due to primary or secondary mitochondrial malfunction.

Mitochondrial dysfunction in friedreich's ataxia.

Friedreich ataxia (FRDA) is an autosomal recessive degenerative disorder caused in the vast majority of cases by a GAA triplet expansion in the FRDA gene on chromosome 9q13. The FRDA gene product, frataxin, is a widely expressed mitochondrial protein which is severely reduced in FRDA patients. Loss of the homologue of frataxin in yeast is associated with mitochondrial iron overload, increased sensitivity to oxidative stress and profound deficit of oxidative phosphorylation. The demonstration that the human pathology of FRDA is also characterised by mitochondrial iron accumulation, deficit of respiratory chain complex activities and in vivo deficit of tissue energy metabolism establishes FRDA as a 'new' nuclear encoded mitochondrial disease.

Double-blind report on the efficacy of lactic acid-producing Enterococcus SF68 in the prevention of antibiotic-associated diarrhoea and in the treatment of acute diarrhoea.

A multicentre double-blind, placebo-controlled clinical trial, involving 123 patients at 10 centres, was carried out to assess the efficacy of a preparation of lactic acid-producing Enterococcus SF 68 in the prevention of antibiotic-associated diarrhoea and in the treatment of acute diarrhoea. In the prevention study, 45 patients being treated with antibiotics were given, concurrently, one capsule twice daily of either Enterococcus SF68 or placebo. Acute diarrhoea was present in 78 patients who were given the same treatment but three times daily. All treatments were continued for 7 days. Enterococcus SF 68 was shown to be effective in reducing the incidence of antibiotic-associated diarrhoea in comparison with placebo (8.7% compared with 27.2%, respectively). Patients with acute enteritis showed a significantly faster resolution of bowel abnormalities during treatment with Enterococcus SF68 compared with placebo.
