Hepatic Function Predictive Value of Hepatic Venous Waveform versus Portal Vein Velocity in Liver Cirrhosis.

Background: This study assessed the hepatic vein waveform (HVW) and mean maximum portal vein velocity (MM-PVV) on Doppler ultrasound in patients with liver cirrhosis (LC) and compared it with that of age and sex-matched controls. It correlated the degree of HVW abnormality and MM-PVV changes with liver function based on Child-Turcotte-Pugh (CTP) to determine which was more predictive of CTP.

Methods: Sixty patients with LC and 60 healthy controls were consecutively recruited into this study.

Correlation of Foetal Liver Length with Gestational Age and Foetal Weight in Pregnant Nigerian Women.

Background: This study aims to determine the relationship(s) of fetal liver length (FLL) to the gestational age, biometric parameters (BPD, FL, AC, HC), and fetal weight in third trimester pregnancies.

Methodology: This was a hospital-based cross-sectional study of 400 fetuses in normal third trimester pregnancies recruited from the Obstetrics and Gynaecology department of OAUTHC, Ile-Ife, Nigeria. The participants were between 20-45 years of age and their gestational ages ranged from 27-40weeks.

Renal arterial resistance index among subjects with liver cirrhosis in a Nigerian population.

Purpose: To describe the relationship between renal artery resistance index (RARI) and liver function based on Child-Pugh system among patients with liver cirrhosis (LC) in Southwest Nigeria.

Methods: About 50 patients with LC and 50 controls were consecutively recruited into this prospective comparative case control study. Each LC patient was classed based on Child-Turcotte-Pugh (CTP) system after relevant tests.

Association between Endothelial Dysfunction, Biomarkers of Renal Function, and Disease Severity in Sickle Cell Disease.

Background: Endothelial dysfunction (ED), as ascertained by brachial artery flow-mediated dilation (FMD), is a known feature of sickle cell disease (SCD), which is present both in crisis and in steady state. The assessment of FMD was introduced to examine the vasodilator function. Our objective was to establish the relationship between ED determined by FMD, biomarkers of renal dysfunction, and biomarkers of disease severity in SCD subjects asymptomatic of renal disease.

Doppler ultrasonographic evaluation of celiac and mesenteric arteries in subjects with sickle cell disease.

Vasculopathy, as occurring in sickle cell disease (SCD), can affect celiac and mesenteric arteries and result in stenosis, with elevated peak systolic velocity (PSV) on Doppler ultrasonography. In six subjects with confirmed SCD in steady state, routine Doppler ultrasonographic examination discovered features of celiac artery (CA) or superior mesenteric artery (SMA) stenosis with CA PSV >200 cm/s (median = 222.8 cm/s; range = 201.

Intima-media thickness of the common femoral artery as a marker of leg ulceration in sickle cell disease patients.

Leg ulceration is a debilitating chronic complication of sickle cell disease (SCD) the pathogenesis of which is yet to be fully elucidated. We hypothesized that SCD patients with histories of previous leg ulcers would have intima hyperplasia of the common femoral artery (CFA). We enrolled 44 SCD patients and 33 age-matched and sex-matched controls with hemoglobin AA.
