ABSTRACT
Patients with type 1 diabetes are at greater risk of cardiovascular disease and atherosclerosis. Carotid in-timamedia thickness (CIMT) measured by ultrasound is a marker of atherosclerosis and can predict future cardiovascular events.The aim of this study was to measure the CIMT in paediatric type 1 diabetes patients in Ibadan and Lagos and compare results with the CIMT of non-diabetic healthy control children. Carotid ultrasound was performed and CIMT measured in 70 subjects (35 diabetic patients and 35 non-diabetic controls matched for age and sex). Mean age was 12.8±3.2 years. A slightly higher, but non-significant mean CIMT was seen in diabetic cases: mean values in type 1 diabetes patients were 0.475±0.068 and 0.476±0.069 (right and left respectively) while in controls, mean values were 0.467±0.064 and 0.468±0.054 (p=0.618 and 0.575 respectively). The CIMT in both groups correlated positively with age and body mass index (BMI). Significantly higher mean CIMT values were seen in males with type 1 diabetes on both sides. However, there was no significant correlation between CIMT and duration of illness, insulin dosage, or blood pressure. CIMT is a safe and convenient measurement, which may be helpful in predicting an increased risk of future cardiovascular disease in children with type 1 diabetes

Aims: The diameter of the posterior atrium of the lateral cerebral ventricles (PALV) does not vary substantially in size during foetal development and has thus become a stable marker for the identification of foetal ventriculomegaly in developed countries. Currently, the accepted upper limit of PADLV is 10 mm. Ventricular atrial diameters greater than 10mm require more radiological evaluation to rule out ventriculomegaly. The aim of this study was to establish the normal range of values for the posterior atrium [PA] of foetal lateral ventricles in our environment and to determine a cut-off value for prenatal diagnosis of ventriculomegaly. Methods: The mean of two measurements was obtained from the transverse diameter of the atrium of the lateral ventricles of foetuses that met the inclusion criteria, as part of the routine obstetric ultrasound scan at the antenatal clinic or ultrasound suite of radiology department of the University College Hospital (UCH), Ibadan. The SPSS version 15 was used to analyse the data obtained. Results: The mean posterior atrial diameter [PAD] of the lateral ventricl was 6.5mm with standard deviation (SD) 1.3mm and mean ±2SD 3.9–9.1mm. Male foetuses had larger atrial diameters than female. Student’s t-test and Pearson’s correlation coefficient were used to explore association. Conclusion: With the existing resources in our environment, prenatal screening for ventriculomegaly during routine obstetric scan is achievable. Measurement of 10mm is a reasonable upper limit of normal in our environment. Foetuses with larger values need further evaluation to rule out hydrocephalus.
ABSTRACT
Background: Gallstones (GS) in the gallbladder (GB) can be responsible for a whole spectrum of disease entities which may lead to a surgical emergency with high mortality. Diabetes mellitus (DM) is a debilitating disease that affects all systems in the body; and literature documents a higher incidence of gallstone disease (GSD) and its complications in diabetics than in the non-diabetic population. Most local studies on the association between GS formation and DM have focused on type 2 diabetics. This study was therefore designed to determine the prevalence of GS in both type 1 and type 2 DM and elucidate the demographic and social factors associated with formation of GS in diabetic patients. Materials and Methods: Four hundred diabetic patients aged between 15 and 82 years had abdominal ultrasound to diagnose or exclude the presence of GS. Results: GS was found in 70 (17.5) of the 400 patients. Positive cases had a male to female ratio of 3:4 and 59 (51.92) were above the age of 40 years with type 2 DM. Body mass index (BMI) greater than 25 kg/m 2 was seen in 56 (48.3) patients; smoking and alcohol intake were insignificantly implicated. Jaundice was recorded in 8 (11.4) while abdominal pain was in 24 (34.3) patients; and 52 (74.3) patients of those with GSD had had diabetes for more than 4 years. Conclusion: GSD in DM is influenced significantly by age; BMI; and duration of the disease; while gender; social factors; and parity do not influence as strong associated factors
