The makeshift city: towards a global geography of squatting

This paper introduces a set of analytical frames that explore the possibilities of conceiving, researching and writing a global geography of squatting. The paper argues that it is possible to detect, in the most tenuous of urban settings, ways of thinking about and living urban life that have the potential to reanimate the city as a key site of geographical inquiry. The paper develops a modest theory of ‘urban combats’ to account for the complexity and provisionality of squatting as an informal set of practices, as a makeshift approach to housing and as a precarious form of inhabiting the city

Medium-energy shock wave therapy in the treatment of rotator cuff calcifying tendinitis

To evaluate the results of the treatment with medium-energy extracorporeal shock wave therapy (ESWT) in rotator cuff calcifying tendinitis. Fifty-four non-consecutive patients, who were referred to our institute for rotator cuff calcifying tendinitis, were managed with a standardized protocol in four sessions of medium-energy (0.11 mJ/mm2) ESWT administered with an electromagnetic lithotriptor. Pain was evaluated at the end of each session, functional state of shoulder was assessed at 1 and 6 months after the end of procedure. All patients underwent radiographs and sonography imaging. No systemic or local complications. Thirty-eight patients (70%) reported satisfactory functional results. Radiographs and sonographs showed a disappearance of calcium deposit in 29 patients (54%) and in 19 patients (35%) it appeared to be reduced more than a half. A correlation was found between residual calcium deposit and the clinical outcome, but some patients showed a reduced pain without modification of calcium deposit. These results were unmodified at 6 months follow-up. Our protocol of medium-energy ESWT provides good results overall about pain modulation

Catabolic enzyme activities in relation to premigratory fattening and muscle hypertrophy in the gray catbird ( Dumetella carolinensis )

The flight muscles of the gray catbird ( Dumetella carolinensis ) were examined to determine if short term adjustments occur in the activity of key catabolic enzymes during preparation for long distance migration. The aerobic capacity of the pectoralis muscle as indicated by citrate synthase activity (CS) is among the highest reported for skeletal muscle (200 μmoles [min·g fresh mass] −1 at 25°C). The mass specific aerobic capacity as indicated by CS activity or cytochrome c concentration does not change during premigratory fattening (Fig. 2) or in relation to the muscle hypertrophy that occurs concomitantly. The maintenance of mass specific aerobic capacity indicates that the total aerobic capacity increases in proportion to the increase in muscle size. The augmented potential for total aerobic power output is considered an adaptation to meet the increased power requirements of flight due to the increased body mass. Additionally, the capacity to oxidize fatty acids, as indicated by β-hydroxyacyl-CoA dehydrogenase activity, approximately doubles during premigratory fattening (from 35 to 70 μmoles [min·g fresh mass] −1 at 25°C; Fig. 1A). This adaptation should favor fatty acid oxidation, thereby sparing carbohydrate and prolonging endurance. The activity of phosphofructokinase, a key glycolytic enzyme, does not change before migration.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47125/1/360_2004_Article_BF01101461.pd

Réhabilitation post-orthodontique des séquelles de fente alvéolaire : implantation ou chirurgie plastique parodontale ?

De même que de nombreuses malformations craniofaciales, les fentes labio-maxillo-palatines font l'objet d'une prise en charge thérapeutique précoce et suivie dans le temps. Tout au long de la croissance, des actes ponctuels et des réévaluations vont intervenir selon un schéma propre à chaque équipe hospitalière. En fin de croissance, après traitement orthopédique et orthodontique visant à l'obtention d'un équilibre esthétique et fonctionnel, une réhabilitation prothétique finale est très souvent nécessaire. Lorsqu'un espace édenté a été maintenu ou recréé entre les dents proximales de chaque fragment, deux solutions se présentent au praticien odontologiste : l'implantation ou la prothèse conjointe traditionnelle. Les perturbations anatomiques séquellaires, profondes et superficielles, sont analysées pour dégager une voie thérapeutique préférentielle vers la reconstruction morphologique crestale par chirurgie plastique parodontale

An evaluation of the radiological changes around the Grammont reverse geometry shoulder arthroplasty after eight to 12 years

Radiological changes and differences between cemented and uncemented components of Grammont reverse shoulder arthroplasties (DePuy) were analysed at a mean follow-up of 9.6 years (8 to 12). Of 122 reverse shoulder arthroplasties implanted in five shoulder centres between 1993 and 2000, a total of 68 (65 patients) were available for study. The indications for reversed shoulder arthroplasty were cuff tear arthropathy in 48 shoulders, revision of shoulder prostheses of various types in 11 and massive cuff tear in nine. The development of scapular notching, bony scapular spur formation, heterotopic ossification, glenoid and humeral radiolucencies, stem subsidence, radiological signs of stress shielding and resorption of the tuberosities were assessed on standardised true anteroposterior and axillary radiographs. A scapular notch was observed in 60 shoulders (88%) and was associated with the superolateral approach (p = 0.009). Glenoid radiolucency was present in 11 (16%), bony scapular spur and/or ossifications in 51 (75%), and subsidence of the stem and humeral radiolucency in more than three zones were present in three (8.8%) and in four (11.8%) of 34 cemented components, respectively, and in one (2.9%) and two (5.9%) of 34 uncemented components, respectively. Radiological signs of stress shielding were significantly more frequent with uncemented components (p < 0.001), as was resorption of the greater (p < 0.001) and lesser tuberosities (p = 0.009)
