Asymmetric induction by the cholestanic moiety on tropos species: synthesis and stereochemical characterization of bile acid-based biphenyl phosphites.

Three different bile acid-derived biphenyl phosphites were synthesized, starting from cholic and deoxycholic acids and biphenol, and their stereochemical features were checked by CD and NMR spectroscopies. On the basis of the spectroscopic results, the capability of the cholestanic system to induce a prevalent sense of twist on the biphenyl moiety of the bile acid-derived phosphites as well as their tropos nature was inferred.

[Our experience in the treatment of intrathoracic and intraspinal hourglass neurogenic neoplasms].

The authors describe their experience in the treatment of dumbbell neurogenic tumours, intrathoracic and intraspinal, with particular reference to clinical presentation, diagnostic for imaging, anatomo-pathological classification and surgical treatment, comparing their clinical cases (9) with the international literature, accurately reviewed. The authors think that the best surgical treatment is the combined approach, in only one stage, of thoracic surgeon and neurosurgeon by hemilaminectomy and extended costotrasversectomy, reserving hemilaminectomy and thoracotomy only for the tumours with big dimension of intrathoracic portion.

Toxic PCB congeners and organochlorine pesticides in Italian human milk.

Human milk from four major Italian cities was analyzed for individual congeners of polychlorinated biphenyls (PCB), DDT, DDE, hexachlorobenzene, and beta-hexachlorocyclohexane. Minimum and maximum concentrations in milk from individual mothers for most compounds ranged between one order of magnitude below and above the mean value of all mothers. Good agreements were found between results from pooled samples and mean values of individual samples. No statistically significant difference between cities was found and the levels in milk from Italian mothers did not differ significantly from published levels from other parts of the world. Principal component analyses revealed that the PCB congener distribution pattern was very similar in all mothers, independent of location. Average concentrations in milk from the four cities were 19(+/- 5) micrograms liter-1 total PCB or 3.2(+/- 0.8) ng liter-1 toxicity equivalents according to the most conservative TCDD toxicity equivalent factors of PCBs proposed in the literature, 70(+/- 18) micrograms liter-1 DDE, 4.5(+/- 1.2) micrograms liter-1 DDT, 5.6(+/- 1.9) micrograms liter-1 HCB, and 4.4(+/- 1.7) micrograms liter-1 beta-hexachlorocyclohexane.

[Obturator hernia].

Obturator hernia, which is a rare cause of intestinal occlusion, generally presents non-specific signs and symptoms. Radiology may be sometimes useful for the diagnosis. Four cases of obturator hernia are described, and the possible surgical access routes are illustrated, emphasizing the use of prosthetic mesh.

[Splenic arteriovenous fistula (a clinical case)].

A splenic arteriovenous fistula is a situation often presenting with signs of portal hypertension and with a characteristic murmur. Though rare, the possibility of a splenic arteriovenous fistula must be borne in mind in differential diagnosis, since it can be corrected surgically by resolving the portal hypertension.
