Etude de la variation de l'épaisseur centrale de la cornée au cours d'une hyperglycémie de novo / Study of the variation of the central thickness of the horn during de novo hyperglycemia

Introduction : L'épaisseur centrale de la cornée peut être modifiée au cours d'une hyperglycémie chronique. En dehors d'une hyperglycémie chronique, nous pensons que les modifications de l'épaisseur cornéenne surviennent également lors des hyperglycémies de novo.Objectif: Déterminer la variation de l'épaisseur centrale de la cornée au cours d'une hyperglycémie de novo.Patients et Méthodes : Il s'agissait d'une étude observationnelle et transversale à visée analytique réalisée de juillet à novembre 2021, auprès de 222 personnes (444 yeux) présentant une hyperglycémie récente. L'ECC a été comparée entre le moment du diagnostic (J0) et 30 jours (J30) après l'initiation du traitement hypoglycémiant (Chi-2). La variation de l'ECC entre J0 et J30 a été corrélée à celle de la glycémie (Spearman ; p<0,05).Résultats : A J0, la moyenne de l'ECC était de 552,5±39,2 µm contre 538,0±34,2 µm à J30 (p=0,001) et celle de la glycémie de 18,1±8,2 mmo/L contre 6,9±3,0 mmol/L (p = 0,001). A J0, 57,0% avaient une ECC > 550µm et à J30, 19,4% avaient diminué cette épaisseur entre 520 et 550 µm et 3,4% à moins de 520 µm. Sur un effectif de 444 yeux, 28,2% (n = 125) ont diminué leur ECC de 25 µm et plus après initiation du traitement hypoglycémiant. Aucune corrélation n'existait entre la variation de l'ECC et celle de la glycémie (r=0,018; p=0,704).Conclusion : Ces résultats montrent qu'il existe une variation de l'ECC en cas de déséquilibre glycémique récent

Introduction : The central thickness of the cornea can be changed during chronic hyperglycemia. Apart from chronic hyperglycemia, we believe that changes in corneal thickness also occur during de novo hyperglycemia.Objective: To determine the variation in the central thickness of the cornea during de novo hyperglycemia.Patients and Methods: This was an observational and cross-sectional analytical study conducted from July to November 2021, involving 222 people (444 eyes) with recent hyperglycemia. ECC was compared between the time of diagnosis (D0) and 30 days (Day 30) after initiation of hypoglycemic (Chi-2) therapy. The change in ECC between J0 and J30 was correlated with that of blood glucose (Spearman ; p<0,05).Results: ON D0, the mean ECC was 552.5±39.2 µm versus 538.0± 34.2 µm on D30 ( p=0.001) and the blood glucose mean was 18.1±8.2 mmo/l versus 6.9±3.0 mmol/l ( p=0.001). On D0, 57.0% had an ECC ˃ 550µm and on D30, 19.4% had decreased this thickness between 520 and 550 µm and 3.4% to less than 520 µm. On a population of 444 eyes, 28.2% ( n=125) decreased their ECC by 25 µm and more after initiation of hypoglycemic therapy. There was no correlation between the change in ECC and the change in blood glucose (r=0.018; p=0.704).Conclusion : These results show that there is a variation in ECC in case of recent glycemic imbalance

Skinfold thickness in normoglycemic offspring of patients with t2dm on graded exercise

It is uncertain if exercise can influence the occurrence of T2DM in offspring of diabetic parents. Therefore this study was designed to assess the effect of exercise on skinfold thickness of offspring of T2DM parents compared with those of non-diabetic parents. This study involved convenience sampling of 50 offspring of T2DM parents attending University College Hospital, Ibadan and 50 offspring of nondiabetic parents who were undergraduate students of the University of Ibadan, Nigeria. Participants were randomly assigned into four groups using convenience sampling method: 25 Normal-weight Offspring of Non-Diabetic Parents (NONDP), 25 Normal-weight Offspring of Diabetic Parents (NODP), 25 Overweight Offspring of Non-Diabetic Parents (OONDP) and 25 Overweight Offspring of Diabetic Parents (OODP). Each participant followed a protocol of graded exercise using the "Tummy trimmer" everyday spending 30-45 minutes daily for 24 weeks. 4 sites of skinfold thickness (supra-iliac, Biceps, Triceps and sub-scapula) were measured by skinfold caliper. Weight and Body Mass Index (BMI) were estimated using standard methods at baseline, 6 weeks, 12 weeks, 18 weeks and 24 weeks, respectively. Data were analyzed using descriptive statistic and repeated ANOVA with p-value at n less than 0.05. The results indicate that compared to baseline, there were reductions at the four sites of skinfold thickness measurements (supra-iliac, Biceps, Triceps and sub-scapular). At supra-iliac site, skinfold thickness in NONDPreductions was from 7.16 mm ± 2.02 to 6.60 mm ± 4.40. The reduction trend for supra-iliac, Biceps, triceps and subscapular skinfold sites in NONDP were 0.56 mm, 0.79 mm, 1.66 mm and 0.19 mm respectively. While the reduction trend for supra-iliac, Biceps, triceps and subscapular skinfold sites in OODP were 0.56 mm, 1.10 mm, 2.06 mm and 1.52 mm respectively. At subscapular site, the average skinfold thickness reduction trend was 0.19 mm in control group 1.53 mm in test group. Thus, graded exercise reduced skinfold thickness in all the groups. The clinical importance of this in prevention of DM among offspring of diabetic parents is quite promising

SKINNY - SKIN Thickness and Needles in the Young

Background. Intensive diabetes management requires the use of multiple daily injections. Inappropriate insulin injection technique; inadvertent intramuscular (IM) injections; needle phobia and insulin omission negatively affect glucose control.Objectives. To document skin and skin plus subcutaneous skin thickness using high resolution ultrasound (US) in a group of children and adolescents with type 1 diabetes. In addition; injection technique; needle re-use and injection site analysis was performed.Methods. Commonly recommended injection sites were examined using high-resolution US. Patient characteristics such as age; body mass index; frequency of injections and favoured sites were analysed. Results. A total of 40 paediatric and adolescent children aged 4 years 3 months to 18 years were examined. The maximum skin thickness at any site was 2.93 mm. A high rate of IM injection was predicted with the standard 8 mm needle and was reduced but not eliminated with the use of the shortest available 4 mm needle. As the subcutaneous skin thickness increased across injection sites in the following order: arm; thigh; abdomen and buttocks; the risk of IM injection declined.Conclusion. Choice of needle length; injection site and injection technique are important considerations in diabetes management in the paediatric population and are likely to affect quality of glycaemic control. Shorter needles are more acceptable and reduce the risk of IM injections

Skinfold Parameter as Predictor of Body Density for Undergraduate Female Students in a Nigeria University Community

The purpose of this study was to determine if some selected skinfold parameters are visible in predicting body density (BD) of undergraduate female students of Obafemi Awolowo University; lie Ife.Methods: Seventy five non- athletic female students; age ranged from 18 to 30 years old from Obafemi Awolowo University (OAU) lie Ife; Nigeria participated in the study. Underwater weight was measured using Hydrostatic Weighing (HSW) equipment and skinfold was measured with Lange skinfold calipers using standard protocol at chest; biceps; triceps; forearm; mid axillar; subscapular; abdomen; supra illiac; thigh and lateral calf. Body density (BD) was calculated with underwater weight and skinfold measurement using some established equations. Descriptive statistics and Pearson Moment Correlation coefficient was used to analyze the data collected.Results: The result showed that BD by HSW had significant negative correlation with skinfold at chest (r = - .505; p .001); biceps (r
