Correct endodontic treatments will be produced if the quality control of intra-operatory dental roentgengraphic displays an adequate periapical coverage. The degree of anatomic accuracy of Rx images depends on correct technical procedure which includes exposure, angulation, object-film and focal-film distance. According to many Authors only the paralleling extended-distance technique provides the minimum of dimensional distortion.

The Italian Cooperative Group on AIDS-related tumors has collected 435 cases of HIV-associated tumors since December 1986. The following conclusions can be drawn from this IVDA-based series: (1) at least 15% of AIDS cases are associated with tumors; (2) the number of malignant lymphomas (high-grade non-Hodgkin's lymphoma [NHL], Hodgkin's disease [HD] is comparable to that of Kaposi's sarcoma (KS) (188 vs. 198); (3) KS among AIDS patients is less common than in countries where homosexual men are the main group affected by AIDS. However, KS also affects intravenous drug abusers (IVDA) almost exclusively males, with characteristics similar to those observed among homosexual men; (4) HD is associated with an aggressive course; (5) anal and oral primary tumors as well as oral and anal involvement of NHL are very rare; (6) testicular cancers occur in patients mainly with early HIV infection, without adversely affecting the dosage of radiotherapy and chemotherapy; (7) cervical cancer successfully treated with conization suggests that PAP test screening in young IVDA women is warranted; (8) lung cancer occurs in a young age group with rapid progression and death.

Prediction of success rate for stainless steel crowns in literature is reported to be comparable to Class I amalgams. This retrospective study shows an analysis of 255 SSC from the stand point of clinical, radiographical and periodontal success.
Restorative treatment of largely destroyed first permanent molars in the mixed dentition involves a few peculiar considerations. Special attention must be given to the restorative-periodontal relationship.

The Authors report main complications of anticoagulant treatment. Particularly, they describe a rare case of hemoperitoneum by spontaneous rupture of the gallbladder. They discuss etiopathogenesis and consequent clinico-therapeutic implications.

Polycentric 384-month study of biofiltration (BF) with AN69s. Since January 1984, 39 uremic dialyzed patients have been included in a randomized prospective study, to evaluate the clinical utility of BF. The trial lasted 9.85 months/pt (384.15 months of total observations) and patients admitted had some not well controlled clinical signs: major acidosis, intradialytic cardiovascular instability, intolerance to acetate dialysis, hypercatabolism, neuropathy, etc. We obtained some positive effects: the incidence of intradialytic hypotension decreased 26.6%; interdialytic body weight gain fell from 3.1 to 2.7 kg (p less than 0.05) and the dialytic time per week was reduced from 12.3 to 10.0 hours (p less than 0.01). At the same time dry body weight increased from 62.4 to 64.6 kg with worthwhile improvement of the acid-base status (ABS) in all patients. This controlled trial showed that BF is particularly useful for patients suffering from severe acidosis and/or cardiovascular instability.
