The population protocol model provides theoretical foundations for analyzing the properties emerging from simple and pair wise interactions among a very large number n of anonymous agents. The problem tackled in this paper is the following one: is there an efficient population protocol that exactly counts the difference k between the number of agents that(More)
BACKGROUND Patients with self-induced water intoxication usually tolerate a large, rapid increase in plasma sodium without developing osmotically induced central pontine myelinolysis. However, we have previously reported a case of clinically suspected pontine myelinolysis in a patient with self-induced water intoxication. The purpose of our study was to(More)
INTRODUCTION Adverse neurological and renal effects can occur in patients taking acyclovir. Neurotoxicity of acyclovir results from an accumulation of the antiviral and its metabolites in the bloodstream. This can be observed in the elderly or in patients with chronic renal failure, generally in dialysis patients. Acute renal failure results from(More)
Type 1A of Charcot-Marie-Tooth disease (CMT1A) is associated with a microduplication of chromosome 17 (region 17p11.2) which contains PMP22, an important gene for peripheral nerve myelination. Patients carrying two duplications are expected to have a more severe phenotype, close to the Dejerine-Sottas syndrome. In this article, we report a family of 5 CMT1A(More)
We report a familial case of Niemann-Pick disease type C which lasted until adulthood, and which had the characteristic deficiency in cholesterol esterification from exogenous cholesterol. A review of the literature was performed concerning cases which were seen in adults and were characterized biochemically. This study showed the frequency of supranuclear(More)
The computational model of population protocols is a formalism that allows the analysis of properties emerging from simple and pairwise interactions among a very large number of anonymous finite-state agents. Significant work has been done so far to determine which problems are solvable in this model and at which cost in terms of states used by the agents(More)
The context of this work is the well studied dissemination of information in large scale distributed networks through pairwise interactions. This problem, originally called rumor mongering, and then rumor spreading has mainly been investigated in the synchronous model. This model relies on the assumption that all the nodes of the network act in synchrony,(More)
A thirty-three-year-old patient developed polyradiculoneuritis with several post-therapeutic relapses despite excellent response to treatment by intravenous polyvalent gammaglobulin. After the second relapse, positive titres for Borrelia burgdorferi were found in serum and C.S.F. We gave her intravenous antibiotic and clinical signs and electrophysiological(More)
We observed 40 patients aged from 15 to 40 years who suffered either a transient ischemic attack or an arterial ischemic stroke. All patients were clinically and physically examined, i.e. chest-X rays, electrocardiograms, biological tests and C.T. scan or magnetic resonance imaging that confirmed the diagnosis of ischemic cerebral infarction. Most patients(More)
We report the results of a combined of chemotherapy with CDDP and 5 FU repeated every 3 weeks in sixteen men (age range 31-73 years) with brain metastases. CT was performed after 2, 4 and 6 cycles to assess efficiency. Response was considered complete when no lesion was found on the CT scan and partial when the lesion shrunk to least half its the total(More)
