Short-chain fatty acids produced by anaerobic bacteria of the periodontal pockets inhibit lymphocytes activation. The highest degrees of immunosuppressive activity is produced by butyric acid.

A total of 60 pediatricians from the districts of Genova and Savona, randomly selected, responded to a survey designed to determine several aspects of their attitude toward the prevention of dental caries and particularly the use of fluoride supplement (table II). The survey demonstrated (table III) that 80% of the physicians prescribe fluoride without knowing the fluoride content in the water supply of their region. Therefore, the dosage schedule used by 56% of the physicians is higher than the optimal, 27.5% is lower and only 16.5% use the optimal dosage as recommended by the American Academy of Pediatric, Committee on Nutrition.
The purpose of this paper is to check the usefulness of dynamic phonocardiography for mitral valve prolapse (MVP) diagnosis, especially in apparently silent cases, or with late-systolic click. In fact, possible MVP or mitral valve regurgitation can be shown. 148 patients (58 males, 90 females) have been examined by basal and dynamic phonocardiography and M-echocardiography. Patients were recruited for routine medical examination or during investigations for other causes or to explain evocative MVP troubles. Provocative tests by amyl nitrite, isoproterenol and methoxamine registered a late-systolic click in 17 normal cases and a late-systolic murmur in 22. M-echo demonstrated MVP in 142 cases (96%), with a slight prevalence of late-systolic MVP; tricuspid valve prolapse coexisted in 8 cases and aortic regurgitation in 12. Today echocardiography is the most important examination, but all our data point to the usefulness of dynamic phonocardiography for MVP diagnosis: in our opinion, the integration of both techniques represents the most correct approach.
Short-chain fatty acids produced by anaerobic bacteria inhibit attachment and proliferation of gingival fibroblasts. Butyric acid, at concentration normally present in periodontal pockets, produced the highest degree of activity.

On the basis of personal experience during the past five years, the anaesthesiological and resuscitatory problems of neonatal surgery are considered, with special regard to the following pathological conditions: oesophageal atresia, diaphragmatic hernia, omphalocele and gastroschisis, neonatal peritonitis, anal atresia, intestinal atresia and stenosis. It is stated that the new post-operative care tecniques have not only improved survival percentages, but, in the case of oesophageal atresia, have made it possible to operate (radically) even in seriously immature babies with ongoing complications.
