Cerebrospinal Fluid Pressure-Related Features in Chronic Headache: A Prospective Study and Potential Diagnostic Implications

Objective: To identify the pressure-related features of isolated cerebrospinal fluid hypertension (ICH) in order to differentiate headache sufferers with ICH from those with primary headache disorder.Methods: In this prospective study, patients with refractory chronic headaches and suspected of having cerebrospinal fluid-pressure elevation without papilledema or sixth nerve palsy, together with controls, underwent 1-h lumbar cerebrospinal fluid pressure monitoring via a spinal puncture needle.Results: We recruited 148 consecutive headache patients and 16 controls. Lumbar cerebrospinal fluid pressure monitoring showed high pressure and abnormal pressure pulsations in 93 (63 %) patients with headache: 37 of these patients with the most abnormal pressure parameters (opening pressure above 250 mm H2O, mean pressure 301 mm H2O, mean peak pressure 398 mm H2O, and severe abnormal pressure pulsations) had the most severe headaches and associated symptoms (nocturnal headache, postural headache, transient visual obscuration); 56 patients with the less abnormal pressure parameters (opening pressure between 200 and 250 mm H2O, mean pressure 228 mm H2O, mean peak pressure 316 mm H2O, and abnormal pressure pulsations) had less severe headaches and associated symptoms.Conclusions: Nocturnal and postural headache, and abnormal pressure pulsations are the more common pressure-related features of ICH in patients with chronic headache. Abnormal pressure pulsations may be considered a marker of ICH in chronic headache

Dating the contexts (or contextualizing the datings?). New evidence from the Southern cemetery at Erimi-Laonin tou Porakou (EC-LC I)

Depuis 2008 , le site d'Erimi-Laonin tou Porakou (Limassol ) fait l ’ objet d ’ une fouille systématique menée par une mission de l ’ Université de Florence en collaboration avec le Département des Antiquités de Chypre . L ’ objectif primaire de l ’ enquête était l ’ analyse du matériel funéraire de la nécropole Sud (Area E ), où plusieurs tombes à chambre individuelle ont été fouillées . Les petits objets et les assemblages céramiques , par leurs typologies et leurs décors , se rapprochent d ’ une production typique de la côte méridionale qui se développe du Chalcolithique ancien au Chalcolithique moyen III / Chalcolithique récent I . Au cours de la saison de fouilles 2010-2011 , des échantillons d ’ ossements ont été prélevés à partir des restes de squelettes de trois tombes (228 , 230 , 248 ), dans le but de réaliser des analyses radiocarbone . Les résultats des études anthropologiques et des datations radiocarbone peuvent être croisés avec le matériel archéologique , afin de dessiner une séquence chronologique de la nécropole d ’ Erimi-Laonin tou Porakou , et d ’ apporter ainsi de nouvelles données à l ’ étude de l ’ Age du Bronze dans la région de Kourion .Chelazi Francesca, Albertini Erika, Calabrisotto Caterina, Bombardieri Luca.

Erimi-Laonin tou Porakou (Limassol, Cyprus): Radiocarbon Analyses of the Bronze Age Cemetery and Workshop Complex

The site area of Erimi-Laonin tou Porakou (Limassol, Cyprus) has been surveyed and systematically excavated since 2007 as a joint research project of the University of Florence and the Department of Antiquities of Cyprus. A focused investigation was dedicated to analyzing funerary evidence from the southern Cemetery (Area E), where 7 single-chamber graves were excavated. The offering goods assemblages from the burials point to a general date ranging from Early to Late Bronze Age I, and draw a sequence of use that is contemporary to the stratigraphic deposits from the top mound Workshop Complex (Area A). During the 2010 field season, charcoal samples from the Workshop Complex and bone samples from the skeleton remains of 2 burials (tombs 228, 230) were opportunely taken for radiocarbon analyses. 14C dating was performed at the AMS-IBA Tandetron accelerator of the INFN-LABEC Laboratory in Florence. This paper will discuss the results of the 14C analyses and compare them with the archaeological evidence in order to outline a chronological sequence for the settlement and cemetery areas at Erimi-Laonin tou Porakou, thus collecting further data on the development and pattern of occupation of the Early to Late Cypriote period in the Kourion area.The Radiocarbon archives are made available by Radiocarbon and the University of Arizona Libraries.
