Mortality from Hodgkin's disease and other lymphomas in Europe, 1960-1990.

Trends in mortality from Hodgkin's disease (HD) and non-Hodgkin's lymphomas (NHL) in the whole of Europe and in two broad European geographic areas (Western and Eastern Europe) were reviewed over the period of 1960-1990, on the basis of official death certifications derived from the World Health Organization database. Between the early 1960s and 1990, HD mortality in the whole of Europe declined from 2.1 to 0.9/100,000 males (-58%), and from 1.1 to 0.5/100,000 (-56%) females. The decline was larger in Western Europe (around 65%), but appreciably smaller in Eastern Europe (around 30%). In contrast, mortality from NHL increased in males from 2.2 to 4.2/100,000 (+93%), and in females from 1.2 to 2.6/100,000 (+112%). These upward trends were larger in Western (over 100%) than in Eastern Europe (around 80%). The declines in HD were larger and the increases in NHL were smaller in populations below age 65. When all lymphomas were considered together, an increase was observed in both sexes (from 4.3 to 5.1/100,000 males; from 2.4 to 3.1/100,000 females) that was comparable in various areas of the continent. These data confirm a major impact of newer integrated diagnostic and therapeutic approaches in reducing HD mortality, while indicating that this impact has been delayed and limited in Eastern Europe. The upward trends in mortality from NHL probably reflect both real increases in incidence and better case ascertainment and certification, but are inconsistent with a noticeable impact of newer therapies on mortality from NHL. It is also conceivable that the introduction of immunophenotypic and immunogenotypic characterization of lymphomas has selectively eliminated from HD a worse-prognosis subset previously classified on the basis of Sternbergoid cells, which has been subsequently classified as NHL. This would have increased survival and decreased mortality from HD, while increasing incidence and mortality from NHL to an extent which is unknown but worth considering.

[Grisel's syndrome. Description of a case of spontaneous subluxation of the atlas].

Grisel's syndrome is an atlanto-axial dislocation affecting children between 6 and 12 years. The outstanding symptom is a spontaneously arising torticollis. The most likely etiology seems to be an inflammation of the retropharyngeal space caused by upper respiratory tract infections or by adenotonsillectomy. Some A.A. consider Grisel' syndrome clinical features strictly due to predisposing conditions. The anamnesis and clinical signs are important clues to diagnosis. The A.A. report a case of an apparently spontaneous torticollis occurred few days after adenotonsillectomy in a 7 years old girl.

[Cerebellar syndrome in a case of Kawasaki disease].

Kawasaky's disease is a multisystem widespread vasculitis. Besides the mucocutaneous patterns, symptoms related to various organs have been observed in the medical literature. Lethargy, irritability, meningism and cranial nerves paralysis occur in the acute phase of central nervous system involvement. The A.A. report a rare cerebellar syndrome caused by vasculitis in a seven years old girl's cerebellum. Surveillance of tardive complications must be undertaken in patients affected by Kawasaky's disease.

[The X-ray fluorescence (XRF) spectrometry of biomaterials used in dentistry. 2].

In this work we analyze the following biomaterial: biomaterials used in this study are: reabsorbable Dac Blu, non reabsorbable Dac Blu, non reabsorbable atomized Dac Blu, non reabsorbable thin Dac Blu, reabsorbable Biocoral 450, Calcitite 2040-12, Orthogel, Apagen, BTF 65, Calcitite 4060-2, Osprogel, Bio-Oss, Biostite, Osprovit, Merck Hydroxiapatite. The quantitative XRF analysis was performed by a Philips PW 1480 with Rh tube. This research, besides underlining the possibility of applying the XRF method to the analysis of biomaterials. This study, shows the facility and the rapidity in the preparation of samples and standards in the form of tablets to undergo the analysis: furthermore the study shows the possibility of verify the analysis on the same sample in the future, because the tablet if well conserved, does not deteriorate. We can also verify a good analytic accuracy both for the principal elements (Ca, P) and for trace elements. The analyses show a moderate variability in the Ca/P ratio in the hydroxylapatites, and a greater variability in the secondary and trace elements.
