[Comparative study of maximal midexpiratory flow rate in normal smoking and non-smoking subjects].

MMF is considered one of the most sensitive parameter to point out initial decay of small airways that should appear prematurely in smokers as compared with non smokers. To verify the above we tested male subjects apparently free from any respiratory disease. They were classed into two groups of equal number: the first group of smokers, the second one of non smokers. We did not find any statistically significant difference between the two groups: this is probably due to the young age of the subjects and consequently to the relative short period of exposure to tobacco smoke.

[Empirical treatment of decompression sickness in Greek sponge divers].

Reports and evidence of the empirical methods of treating decompression sickness long used by Greek sponge divers have been collected. Divers were questioned by a team from Chieti University's School of Underwater and Hyperbaric Medicine during a visit to the island of Kalymnos. There are interesting analogies between modern therapy and ancient empirical methods. The modern methods were devised in response to the enormous incidence of decompression sickness during the fishing season in the Southern Mediterranean. It may well be that the experience of old sponge divers may offer some helpful suggestions for modern therapy of decompression sickness.

[Alveolaro-capillary gas exchange. Considerations on the evaluation of carbon monoxide diffusion].

This study is based on 107 male individuals aged between 20 and 73 years, all of them exempt from any disease. They were submitted to instrument examination for measuring the CO pulmonary diffusing capacity with the single breath method. The data so obtained were then statistically elaborated considering the index value of CO transfer, the Helium partition (RHe) and the CO partition and diffusion (R&DCO). The CO transfer index has shown a particularly extensive range; if we take as normality level-20%, a consistent ratio of individuals (20,56%) falls in a range of deficitary pulmonary diffusion though in absence of aèny clinical evidence of pathology. The subsequent statistical elaboration of the data after logarithmic transformation, by the means of the linear regression model, has allowed to reduce the variance of the R&D CO index improving his classificative capability.

[Use of hyperbaric oxygen therapy in a case of inguino-genital gangrene].

A case of inguinogenital gangrene in a 63 years old man is reported. The patient was admitted to the hyperbaric medicine centre in a serious general condition. The use of HOT, antibiotics and selective surgery as treatment of metabolic disturbances effectively improved the patient's general condition, and HOT also proved effective in the treatment of hepatic insufficiency.

[Carbon monoxide alveolar-capillary diffusion: considerations on inter-personal variability].

Twenty three male subjects 21 to 53 aged were undergone to lung diffusion test using breath holding method. Each subject was tested three times in different days. The results were evaluated by Bartlett's Chi-square test and by Kendall's coefficient of concordance. Correlation between the CO distribution and diffusion index (R&DCO), the Helium distribution index (RHe), the time of breath holding and the volume of "single breath" was found. It seems it will be possible to improve the inter-personal estimation to 1.25% about.

[The influence of helium concentration in determining respiratory function parameters].

Before a research about normals values of lung diffusing capacity for CO in Italian people, the Authors investigate if different concentration of Helium in respiratory gases could have any influence on data. Experiments were performed by testing 8 male subjects. Each one repeated lung function tests three times using gas mixtures with different Helium percentage. Results were evaluated by meaning of t Studnt's and Bartlett's Chi-square tests. Results show no significant difference.

[Stomach rupture due to barotrauma (a report of the 13th case since 1969)].

The thirteenth case of rupture of the stomach after a diving accident since 1969 is reported. This rare event was caused by equipment failure and panic reaction, which induced swallowing air during diving and consequential gas expansion in gastric cavity meanwhile the rapid ascent. Peritoneal decompression by paracentesis quickly improved the patient's condition and the following surgical laparotomy revealed a gastric tear along the lesser curvature, which was closed by suturing. The patient presented a postoperative splenic abscess two months later; literature demonstrated that rupture of a filled stomach may lead to septic complications.
