Ultrasound and CBCT analysis of blood flow and dimensions of the lingual vascular canal: A case control study

Basilar artery dolichoectasia (BAD) is a disorder characterized by dilatation, elongation and tortuosity of the basilar artery. Transcranial Doppler ultrasound (TCD) is a useful tool that can detect blood flow in intracranial vessels including basilar artery (BA). Few studies have been conducted on blood flow changes in BAD. This study was conducted to evaluate the Doppler parameters in dolichoectatic BA and to assess if there is any difference in TCD findings between stroke and non-stroke BAD patients. A case-control study was conducted on 35 patients diagnosed with BAD (26 male, 9 female) and 35 age- and gender-matched control group (without BAD) at the Middle Euphrates Neuroscience Center, Al-Sader Medical City, Al-Najaf, Iraq. Dolichoectasia was diagnosed on non-enhanced brain CT scan using established imaging criteria according to Dan Deng et al criteria. Doppler flow for control and stroke cases was recorded. The parameters measured on TCD were peak systolic velocity (PSV), end diastolic velocity (EDV) mean blood velocity (MBV), pulsatility index (PI) and resistive index (RI). After logistic regression for adjustment for the significant confounders, there was statistically significant difference in Doppler parameters between both groups including decrease in each of PSV, EDV and MBV while both PI and RI weren’t statistically significant. Among BAD patients, there was statistically significant difference in all TCD parameters between stroke and non-stroke patients (PSV EDV, MBV, PI and RI). BAD was associated with a decrease in flow velocities as measured by TCD. Furthermore, among BAD patients, those with stroke had lower values for all Doppler parameters than non-stroke patients.

Background. Anemia among pregnant women is one of the most common public health problems in developing country. World health organization (WHO) estimate shows nearly half of pregnant women were affected by anemia. High burden of anemia is observed in Africa particularly in Ethiopia. However, the factors that contribute to the occurrence of anemia were not exhaustively studied. Therefore, the aim of this study was to identify determinant factors of anemia among pregnant women in Durame Town, southern Ethiopia. Method. An institutional based unmatched case control study was conducted among 111 cases and 222 controls in Durame Town from 16th February to 8th May 2017 using interviewer administered questionnaires. Controls were pregnant women whose hemoglobin level was 11 g/dl and above at their first antenatal care clinics and cases were pregnant women whose hemoglobin level was less than 11 g/dl. Bivariate and multivariate logistic regression model was used to see the determinants of anemia. Adjusted odds ratio (AOR) with 95% confidence interval (CI) and p-value were used to identify the significant association. Result. A total of 333 women (111 cases and 222 controls) participated in the study. The major determinant factors were parasitic infection (AOR: 3.67, 95% CI: 1.72-7.86), not taking additional diet during pregnancy (AOR: 2.49, 95% CI: 1.22-5.08), consuming tea/coffee immediately after food (AOR: 3.58, 95% CI: 1.72-7.42), not eating meat (AOR: 2.07, 95% CI: 1.03-4.15), previous heavy menstrual blood flow (AOR: 2.62, 95% CI: 1.18-5.84), and being housewife (AOR: 2.38, 95% CI: 1.02-5.57). Conclusion. Parasitic infection, additional diet during pregnancy, consuming tea/coffee immediately after food, meat consumption, previous heavy menstrual blood flow, and occupational status of women were significant factors associated with anemia among pregnant women. Therefore, anemia prevention strategy should include promotion of counseling on additional diet during pregnancy, preventing parasitic infection, and increasing employment opportunities for women.
