Cerebrospinal fluid analysis and the determination of oligoclonal bands.

This document presents the guidelines for the cerebrospinal fluid (CSF) analysis and the determination of oligoclonal bands (OCBs) as pivotal tests in neuroinflammatory pathologies of the central nervous system. The guidelines have been developed following a consensus process built on questionnaire-based surveys, internet contacts, and discussions at workshops of the sponsoring Italian Association of Neuroimmunology (AINI) congresses. Essential clinical information on the pathologies in which the CSF analysis is indicated, and, particularly, on those characterized by the presence of OCBs in the intrathecal compartment, indications and limits of CSF analysis and OCB determination, instructions for result interpretation, and agreed laboratory protocols (Appendix) are reported for the communicative community of neurologists and clinical pathologists.

A panel of macroautophagy markers in lymphomonocytes of patients with amyotrophic lateral sclerosis.

A potential role for macroautophagy dysfunction in the pathogenesis of amyotrophic lateral sclerosis (ALS) was hypothesized after the demonstration that selected markers are up-regulated in post mortem samples obtained from both patients and animal models of disease. We hypothesized that a putative dysfunction of this catabolic pathway could be operative also in peripheral blood mononuclear cells (PBMC) obtained from ALS patients, since these cells represent an accessible model for studying molecular pathogenesis events in neuropsychiatric disorders. Beclin-1 and LC3II immunoreactivity were assessed in PBMC from 15 ALS patients and 15 controls by Western blot analysis.

Root resorption of replanted teeth: an SEM study.

Two replanted and subsequently expelled upper central incisors were observed under a scanning electron microscope to study the changes brought about by root resorption. The severity of resorption and the distribution of the affected areas were different in the two specimens. In the first case, large, deep excavations were found along a continuous bone defect which exposed the opposite root canal wall.

[Antibacterial activity of endodontic medications].

Background: The successful outcome of endodontic treatment depends on the elimination of bacteria present inside the root canal system. In the pulpal chronic infection, intracanal medicaments are necessary to obtain the sterilization. This study evaluated the antibacterial activities of some intracanal medicaments.

[Oromaxillofacial changes in thalassemia major].

Sixty patients (31 male and 29 female) with thalassemia major, aged between 6 and 26 years, 18 of which were splenectomized, were observed in this study evaluating the oro-maxillo-facial alterations and correlating them to transfusion indexes, serum ferritin levels, splenectomy and age. For each patient a haematologic and odontostomatologic card was filed with a view to report the medical and clinical history regarding: the haematologic picture, the prevention of caries and parodontal disease, the facies characteristics, the odonto-stomatologic examination, the orthodontic diagnosis, the skull X-rays and the orthopantomography. Poor oral hygiene as well as misknowledge of prevention were generally observed.
