The European spondylarthropathy study group preliminary criteria for the classification of spondylarthropathy

Abstract: Classification criteria for most of the disorders belonging to the spondylarthropathy group already exist. However, the spectrum of spondylarthropathy is wider than the sum of these disorders suggests. Seronegative oligoarthritis, dactylitis or polyarthritis of the lower extremities, heel pain due to enthesitis, and other undifferentiated cases of spondylarthropathy have been ignored in epidemiologic studies because of the inadequacy of existing criteria. In order to define classification criteria that also encompass patients with undifferentiated spondylarthropathy, we studied 403 patients with all forms of spondylarthropathy and 674 control patients with other rheumatic diseases. The diagnoses were based on the local clinical expert's opinion. The 403 patients included 168 with ankylosing spondylitis, 68 with psoriatic arthritis, 41 with reactive arthritis, 17 with inflammatory bowel disease and arthritis, and 109 with unclassified spondylarthropathy. Based on statistical analysis and clinical reasoning, we propose the following classification criteria for spondylarthropathy: inflammatory spinal pain or synovitis (asymmetric or predominantly in the lower limbs), together with at least 1 of the following: positive family history, psoriasis, inflammatory bowel disease, urethritis, or acute diarrhea, alternating buttock pain, enthesopathy, or sacroiliitis as determined from radiography of the pelvic region. These criteria resulted in a sensitivity of 87% and a specificity of 87%. The proposed classification criteria are easy to apply in clinical practice and performed well in all 7 participating centers. However, we regard them as preliminary until they have been further evaluated in other settings.

Dorsal arterial supply to the thumb

Abstract: and emptying 3 times into the left jugulo-subclavian confluence; and 4 times from the RPT (ptd, Fig.4), e m p t y i n g into the lef t venous confluence in 2 cases and once into the arch of the tho rac ic duct . The left suprabronchial group was injected 10 times. The coloring remnained localised 5 times and progressed twice into the aorta, twice into the recurrent chain (Fig.5) or left paratracheal chain and once into the thoracic duct in the medias t inum. From the left atrium the lymphatic vessels joined the lef t c o m m o n c o r o n a r y trunk,injecting the principal left collector and then the RPT. Discussion

An anatomical study of the vascularisation of the first dorsal interosseous space in the hand, and a description of a bony pedicle graft arising from the second metacarpal bone (23.11.90)

Abstract: We have used this vascularised bony graft mainly for recurrent pseudarthrosis of the scaphoid bone. An account of our series will be the subject of a future publication. The use of the vascularised pedicle graft at the expense of the head of the second metacarpal has seemed to us to give encouraging results. The technique, although meticulous, is simple to carry out. The good vascularisation of the graft is assured through the large amount of fatty and connective tissue around the base of the pedicle. The use of vascularised bone in hand surgery has been shown to be useful. This graft, easy to raise, has through the length of its pedicle, a limited displacement. Other donor sites do not have the advantages described here.

The Third Dopamine Receptor (D3) as an Autoreceptor

Abstract: The recently characterized D3 receptor is homologous to the D2 receptor from which it differs by its selective expression in limbic areas of the brain. In addition the autoreceptor function of the D3 receptor is suggested by its pharmacology and expression by dopaminergic neurons.

Immunomodulations of thymocytes and splenocytes in trained rats.

Abstract: The aim of this study was to describe the effects of training (running) on thymus and spleen cells in the rat Young Wistar control rats (n = 6), rats trained for 4 wk (n = 5), and rats trained for 4 wk followed by 1 wk of intensive training (3 h/day, n = 6) were studied Various lymphocyte surface and nuclear markers were determined by immunocytochemistry The results show that 4 wk of training 1) decreased the percentage of bromodeoxyuridine (BrdU+) thymocytes (cell in phase S of the cycle, immature thymocytes; P less than 005) and the viability of thymocytes stimulated with concanavalin A (Con A; P less than 005) and 2) increased the absolute number of CD8+ (suppressor/cytotoxic T cells; 29%) and the percentage of CD8+ splenocytes (P less than 001) An additional week of intensive training in the 4-wk trained rats induced 1) a decrease in the absolute number of thymocytes (25%, P less than 005), TCR+ thymocytes, splenocytes (28%, P less than 001), T, CD4+ (helper T cells; 34%), and CD8+ (31%) splenocytes (P less than 001) and 2) an increase in the viability of splenocytes after stimulation with Con A for 72 h (P less than 005)(ABSTRACT TRUNCATED AT 250 WORDS)

[Post-autistic states: an image of "normality"? Metamorphosis and permanence of autistic strategies].

Abstract: Ludovic is 14 and has spent ten years in a treatment center for autistic conditions. He is in a recovering process: he can talk, he goes to school and now can participate in group activities. But what defines "recovery" from an autistic state? The Rorschach and the TAT bring some interesting light to this question and help in understanding some contemporary concepts and theories as developed by D. Meltzer and F. Tustin among others: what of the "autistic strategies" described in well adapted personalities? (In her book Autistic barriers in neurotic patients F. Tustin speaks of "autistic enclave".) We will also see how our common cultural world can be treated as an "autistic object" and how "demantling"/isolation, followed by "remantling"/sticking, can confer an idiosyncratic configuration to the real world, thus magnificently protecting a necessary omnipotent fantasy, necessary because of the main defense mechanism which is the shifting of position. This mechanism confers to the "I" the statute of a traveller and leaves unworked through the primitive terrors which are concerned with the contact with the object as well as with the separation from it.

Mutagenic activity of the condensates from thermal decomposition of different polyamides

Abstract: The mutagenic activity of the condensates from oxydative pyrolysis of various polyamides at 500, 800 and 1,000 degrees C has been searched for by AMES preincubation test in strains TA 98 and TA 100 with or without metabolic activation by an Aroclor 1254 induced rat liver microsomal S9mix fraction. All condensates are mutagenic in the presence of this fraction and most of them are far less or not mutagenic in the absence of S9mix. Strain TA 98 is more sensitive than strain TA 100 for detecting the mutagenic activity of these condensates. So, they mainly contain indirect mutagenic substances responsible for frameshift mutation. In all cases, mutagenic activity is maximum at 800 degrees C. This observation should draw the attention upon the genotoxic (carcinogenic) long term risk induced by thermal decomposition of plastics and then upon the necessary protection of firemen and others in charge of domestic or hospital solid waste incineration.

Le traitement de texte Word (version anglaise) : conception de cours d'anglais de spécialité

Abstract: Dans un metier ou les technologies devancent les langages, nous devons simultanement proteger les normes et accompagner les novations. De ce fait, nous ne devons pas exercer un proselytisme quelconque en faveur de telle ou telle methode, mais choisir dans chacune la composante la plus adaptee au resultat poursuivi. C'est pourquoi, au departement informatique de l'IUT de Paris V, nous optons pour une approche "info-active".
