Predictive model to identify the risk of losing protective sensibility of the foot in patients with diabetes mellitus

2019

Diabetic neuropathy is defined as the presence of symptoms and signs of peripheral nerve dysfunction in diabetics. The aim of this study is to develop a predictive logistic model to identify the risk of losing protective sensitivity in the foot. This descriptive cross‐sectional study included 111 patients diagnosed with diabetes mellitus. Participants completed a questionnaire designed to evaluate neuropathic symptoms, and multivariate analysis was subsequently performed to identify an optimal predictive model. The explanatory capacity was evaluated by calculating the R (2) coefficient of Nagelkerke. Predictive capacity was evaluated by calculating sensitivity, specificity, and estimation o…

Analysis of F-wave in metabolic neuropathies: a comparative study in uremic and diabetic patients.

1987

Motor nerve conduction study along the entire length of the ulnar and tibialis posterior nerves was carried out in 30 diabetics compared with 30 uremic patients and 30 control subjects. The conduction in the proximal and the distal nerve segments was evaluated by the determination of the M and F latencies, MNCV (between the stimulus sites), FWCV (between the spinal cord and the stimulus sites), and F-ratio (conduction time ratio of proximal to distal segment). In both groups of patients the lower limbs appear much more involved than the upper, where the ulnar nerve is more commonly affected in uremic than in diabetic patients. In diabetic neuropathy the motor conduction abnormalities are di…

Heterogeneous presentation of caspr2 antibody‐associated peripheral neuropathy – A case series

2019

Contactin-associated protein 2-like (caspr2) antibodies have been discovered recently. Since then a multitude of patients with caspr2 antibodies presenting with different neurological symptoms have been reported. Here, we describe three patients with caspr2 antibodies with different types of pain/no pain in combination with peripheral neuropathy. The first patient, a 33-year-old woman, presented with erythromelalgia-like pain and autonomic symptoms; the second patient, a 58-year-old man, with paresthesia and pain while walking together with signs of peripheral motor neuron hyperexcitability in combination with optic neuritis, and the third patient, a 74-year-old man, without any pain but wi…

Association of reduced glyoxalase 1 activity and painful peripheral diabetic neuropathy in type 1 and 2 diabetes mellitus patients

2013

Abstract Aims The present study was undertaken to investigate the relationship between glyoxalase 1 (Glo1) enzyme activity and painful diabetic neuropathy (DN) in patients with diabetes mellitus. Methods Glo1 activity and biochemical markers were determined in blood samples from 108 patients with type 1 diabetes, 109 patients with type 2 diabetes, and 132 individuals without diabetes as a control. Painful and painless peripheral DN was assessed and multivariate regression analysis was used to determine independent association of Glo1 activity with occurrence of painful DN. Results In patients with type 1 and type 2 diabetes mellitus and painful DN compared to patients with painless DN, Glo1…

Oesophageal motility disorders in type 1 diabetes mellitus and their relation to cardiovascular autonomic neuropathy.

2006

The relationship between cardiovascular autonomic neuropathy (CVAN) and oesophageal dysfunction in diabetes mellitus has not been well established because reports are contradictory. The aim of this study was to assess oesophageal function and its correlation with CVAN in type 1 diabetic patients without oesophageal symptoms. Forty-six type 1 diabetic patients without oesophageal symptoms (DG) and 34 healthy volunteers (CG) were studied. Both groups underwent CVAN tests and oesophageal manometry and pH-metry. Differences between groups regarding results of cardiovascular autonomic tests and oesophageal studies were statistically analysed. Compared with the CG, the DG group showed insufficien…

Analysis of thiamine transporter genes in sporadic beriberi

2014

Abstract Objective Thiamine or vitamin B 1 deficiency diminishes thiamine-dependent enzymatic activity, alters mitochondrial function, impairs oxidative metabolism, and causes selective neuronal death. We analyzed for the first time, the role of all known mutations within three specific thiamine carrier genes, SLC19 A2, SLC19 A3 , and SLC25 A19 , in a patient with atrophic beriberi, a multiorgan nutritional disease caused by thiamine deficiency. Methods A 44-year-old male alcoholic patient from Morocco developed massive bilateral leg edema, a subacute sensorimotor neuropathy, and incontinence. Despite normal vitamin B 1 serum levels, his clinical picture was rapidly reverted by high-dose in…

We analyzed for the first time the role of all known mutations within three specific thiamine carrier genes SLC19 A2 SLC19 A3 and SLC25 A19 in a patient with atrophic beriberi a multiorgan nutritional disease caused by thiamine deficiency. Methods: A 44-year-old male alcoholic patient from Morocco developed massive bilateral leg edema a subacute sensorimotor neuropathy and incontinence. Despite normal vitamin B1 serum levels his clinical picture was rapidly reverted by high-dose intramuscular thiamine treatment suggesting a possible genetic resistance. We used polymerase chain reaction followed by amplicon sequencing to study all the known thiamine-related gene mutations identified within the Human Gene Mutation Database. Results: Thirty-seven mutations were tested: 29 in SLC19 A2 6 in SLC19 A3 and 2 in SLC25 A19. Mutational analyses showed a wild-type genotype for all sequences investigated. Conclusion: This is the first genetic study in beriberi disease. We did not detect any known mutation in any of the three genes in a sporadic dry beriberi patient. We cannot exclude a role for other known or unknown mutations in the same genes or in other thiamine-associated genes in the occurrence of this nutritional neuropathy.HumansThiamineGenePolymerase chain reactionGeneticsMutationNutrition and DieteticsbiologyMembrane Transport ProteinsThiamine Deficiencymedicine.diseaseAlcoholismEndocrinologyMutationbiology.proteinThiamineMutations

Effects of high doses of toluene on color vision.

1999

High exposure to toluene may cause optic neuropathy and retinopathy, both associated with dyschromatopsia. Another solvent, ethanol, is known to induce acute blue-yellow dyschromatopsia. This study investigated the acute effects of high doses of toluene on color vision. Eight male printshop workers were examined before and after cleaning printing containers with pure toluene. After cleaning, concentrations of toluene in blood were between 3.61 and 7.37 mg/l. Color vision was tested with the Farnsworth panel D-15 test, the Lanthony desaturated panel D-15 test, and the Standard Pseudoisochromatic Plates part 2. For control of possible acute effects, eight workers of a metal-working factory wi…

Subclinical optic neuropathy in Fabry disease.

2009

Fabry disease is a rare X-linked lysosomal storage disorder, caused by the deficiency of alpha-galactosidase A. Ophthalmic features comprise a cornea verticillata, conjunctival aneurysms, tortuous conjunctival and/or retinal vessels, and anterior and posterior subcapsular cataracts. The issue of a possible subclinical optic neuropathy in Fabry disease has been raised recently. In this pilot study, we looked for signs of optic neuropathy in our cohort of Fabry patients.Thirty-one Fabry patients (15 male, 16 female, mean age 34 years) underwent an ophthalmological investigation consisting of assessment of best corrected visual acuity, slit lamp investigation, testing of pupillary reaction, fu…
