The A3243G mutation of the mitochondrial tRNA(Leu) gene has been recently reported in rare patients with focal and segmental glomerulosclerosis (FSGS). However, the full spectrum of systemic and kidney manifestations in adults presenting with this mutation remains poorly defined. Assessment of renal and nonrenal manifestations was performed in nine patients(More)
The aim of this study is to describe the experience of three haemodialysis centres using indwelling femoral silicone catheter (model SSL 1220M, Medcomp, USA) in 55 patients, three with acute renal failure, one requiring plasmapheresis, and 51 with chronic renal failure but no other available vascular access. Sixty-four catheters were in place for a mean(More)
BACKGROUND Tumour-like calcinosis is a rare cause of tissue calcification in patients on maintenance haemodialysis for chronic renal failure. Its estimated incidence is between 0.5 and 7% of haemodialysis patients. PATIENTS AND METHODS A 29-year-old male patient was referred to our department with a large cervical mass lesion increasing in size for two(More)
Although the association of angiotensin I-converting enzyme inhibitors (ACEis) with a negatively charged membrane is thought to be responsible for hypersensitivity reactions (HSRs) during hemodialysis, we hypothesize that these complications are due to changes in plasma aminopeptidase P (APP) activity and genotype. To test this hypothesis, we measured(More)
Angiotensin I-converting enzyme inhibitors (ACEi), which are used to treat common cardiovascular diseases, are associated with a potentially life-threatening adverse reaction known as angioedema (AE-ACEi). We have previously documented a significant association between AE-ACEi and low plasma aminopeptidase P (APP) activity. With eight large pedigrees, we(More)
Deltamethrin [( S]-alpha-cyano-3-phenoxybenzyl-cis-(1R,3R)-3-(2,2-dibromovinyl+ ++) (2,2-dimethyl-cyclopropane-carboxylate], is the most potent insecticide known at the present time. But it is also one of the most toxic pyrethroids for vertebrates. The toxicity study of deltamethrin was performed on mice and rats, and on anaesthetized dogs, the(More)
OBJECTIVE To establish some therapeutic criteria about the treatment of AVMs of III, IV and V grade of Spetzler and Martin and to analyse the results in the subgroup of preoperative embolization plus surgery. METHODS We perform a retrospective analysis of a group of 31 patients with arteriovenous malformations (AVMs) treated in our center between 1999 and(More)
In the anaesthetized Dog, synthetic substance P in one dose (0.5 mug/kg i.v.) induced a quick hypotensive but short-lasting action and a respiratory analeptic activity which only appeared with some delay and lasted more than one hour. The possibility of a rapid metabolization of synthetic SP is discussed.
Neurophysiological monitoring during surgery to avoid damaging of eloquent brain areas is a useful tool. We are performing intraoperative neurophysiological test to locate motor, sensitive and speech areas with cortical stimulation and cranial nerves during cerebellopontine cranial base surgery. Neurophysiological monitoring during brain stem surgery has(More)
Nuclear medicine can make an efficient contribution to the diagnosis and monitoring of renal disease and to the assessment of therapeutic interventions in the field of renal transplantation. The new radio pharmaceutical MAG 3 labelled with 99mTc provides renal imaging of quality in patients with impaired renal function and enables quantitative evaluation of(More)
