Clinical Profile and middle cerebral artery velocity of children with sickle cell anaemia seen in UUTH, Uyo, Akwa Ibom state, Nigeria.

Background: The risk of stroke in individuals with Sickle Cell Anaemia (SCA) can be assessed by routine non-invasive measurement of their cerebral blood flow using a Transcranial Doppler (TCD) ultrasound scan. This study aimed to determine the difference in blood flow velocity parameters in the middle cerebral artery (MCA) of children with sickle cell anaemia compared to a normal age-matched population.

Methodology: This was a hospital-based comparative cross-sectional study among 40 SCA patients aged 3-16 years, in steady state and 40 age and sex-matched HbAA healthy subjects.

Utility of first trimester obstetric ultrasonography before 13 weeks of gestation: a retrospective study.

Introduction: First trimester pregnancy is defined as twelve weeks after the last menstrual period. Ultrasonography has revolutionized validation and management of first trimester pregnancies. The aim was to analyze ultrasonographic findings of first trimester pregnancies in University of Uyo teaching hospital (UUTH), Uyo, Nigeria.

Clinical practitioners' knowledge of ionizing radiation doses in diagnostic radiology examinations in Calabar.

Background: Observation has shown a preponderance of irrelevant, unjustified and perhaps unnecessary radiological requests in the study area. The consequences of this on the patients' doses and population collective dose may be dire.

Objective: To assess Clinicians/Referrers' knowledge of radiation doses of patients undergoing radiological examinations.

Effect of x-ray exposure (mAs) on peroxide and acid values of honey.

Honey is used in most places as food sweetener and antibacterial agent for wounds. The antibacterial property of honey depends mainly on its peroxide value and acidity. This study investigated the possible effect that may be observed on the peroxide value and acidity if honey is exposed to x-ray at varying tube current values (mAs) in order to infer the possible implications of referring patients undergoing honey therapy for diagnostic x-ray examination.

Dicephalus parapagus conjoined twins discordant for anencephaly: a case report.

Introduction: Cases of conjoined twins occur so rarely that it is important to learn as much as possible from each case.

Case Presentation: We present a case of 9-hour-old, female, Nigerian dicephalus parapagus conjoined twins discordant for anencephaly diagnosed only after the birth of the twins. The anencephalic twin was stillborn while the normal one died within 9 hours of birth from cardiopulmonary failure.
