Carotico-vertebral Doppler Ultrasonography in Patients with Idiopathic Vertigo

Background: In the present study, we investigated the relationship between caroticovertebral Doppler USG measurement results and Vertigo Symptom Scale-Short Form (VSS-SF) in patients with idiopathic vertigo. Methods: Fifty patients with idiopathic vertigo and 30 healthy subjects were included into the study. Ear, Nose & Throat (ENT) examination, audiological examination, routine hemogram, biochemichal tests and temporal magnetic resonance imaging were performed to diagnose “idiopathic vertigo”. By carotico-vertebral Doppler ultrasonography (USG), common carotid artery (CCA) area, intima media thickness; and vertebral artery dimension were measured on the right and left side of the study and control groups. Results: CCA area values were not different between the study and control groups; and between the right and left sides of the each group. On the left side, intima media thickness and vertebral artery dimension values of the vertigo group were significantly higher than those of the control group. Correlation tests showed that CCA area and intima media thickness values on the right and left side were positively correlated with each other. Moreover, in patients with higher right; or left intima media thickness values, left vertebral artery dimensions decreased. Older age was associated with higher intima media thickness in right and left sides. When CCA values decreased on the right side, VSS-SF values increased; and patients’ complaints for vertigo got higher. Linear regression analysis (Backward LR) results also showed that the significant compounding factor on VSS-SF was right CCA area. As right CCA area decreased, VSS-SF increased with more vertigo complaints. Whereas, vertigo complaints and VSS-SF decreased when right CCA increased. Conclusion: We concluded that a decrease in the right CCA were linked with higher VSS-SF scores and increasing vertigo symptoms. Whereas, a decrease in the left CCA area and left crabial blood supply are more important related to the left hemispheric dominance in right-handed people. Moreover, an increase in the intima media thickness was also detected in the vertigo patients and it probably causes a decrease in the central blood flow.

Objective: Endothelial dysfunction and atherosclerosis may be associated with subclinical hypothyroidism (SCH) in multiple ways. The intima-media thickness of the common carotid artery (CIMT) is an important parameter for early atherosclerotic change. Previously several studies addressed the association between SCH and CIMT. Some studies indicate that SCH might be related to increase CIMT, while other studies revealed no significant association. The aim of the study was to further examine the relationship between CIMT and SCH patients in our own laboratory setting in Bangladesh.Patients and Methods: This cross sectional study was carried out at the Institute of Nuclear Medicine and Allied Sciences (INMAS), Dhaka Medical College Hospital Campus, Dhaka during the period of January 2016 to October 2016. The study included 56 consecutive patients. Out of 56 patients, 26 were in SCH group and 30 were in euthyroid control group. CIMT was measured in each subject via High resolution B-mode ultrasonography. Data were analyzed between these two groups in respect to age, sex, BMI, and mean CIMT.Results: Out of 56 subjects, 26 were SCH group and 30 were euthyroid control group. Male to female ratio was 3:23 and 9:21 in SCH and control groups respectively. The mean age was 30±7.4 and 32±8.7 years in SCH and control groups respectively. The mean BMI was 25.6±4.7 kg/m2 in SCH and 25.1±4.1 kg/m2 in control group. The mean CIMT was significantly (p≤0.05) higher in SCH group (Right-0.80±0.05 mm, Left-0.80±0.07 mm) than control group (Right-0.60±0.05 mm, Left- 0.61±0.05 mm). SCH group was further subdivided into two groups with a cut off value of serum TSH at 10 mIU/L. The mean CIMT was significantly higher in SCH with TSH above 10 mIU/L than SCH group with TSH less than 10 mIU/L (p≤0.05). Pearson’s rank correlation test showed significant positive correlation between both CIMT and TSH values.Conclusion: Our study showed that CIMT was significantly higher in SCH group than euthyroid control group. The CIMT values were positively correlated with the TSH values. Therefore we may conclude that SCH is an independent risk factor for atherosclerosis in addition to other classical risk factors.Bangladesh J. Nuclear Med. 19(2): 123-127, July 2016

PURPOSE: To measure the healed areas of osteochondral defects produced in femoral condyles of rabbits filled with biopolymer sugar cane gel and to compare these with those of the control group at 90, 120 and 180 days. METHODS: A study was made of 16 New Zealand rabbits, 6 and 7 months old, weighing between 2 and 2.5 kg. Defects of 3.2 x 4 mm were made, with trephine, in the femoral condyles of the right and left knees. As to the study group defects of the medial and lateral condyles of the right knee were used which were filled with Biopolymer Sugar Cane Gel; as to the Control Group defects of the medial and lateral condyles of the left t knees were used which were left open for natural healing. The defects were analyzed at 90, 120 and 180 days after surgery. After euthanasia, the knees were removed and fixed in Bouin's solution for later digital photographic documentation with a digital camera. The areas healed were measured in both the study and control groups using the images obtained from an Image-J® program. Statistical analysis was conducted using the non-parametric Mann-Whitney test. RESULTS: There were no significant differences between the means of the healed areas in the study and control groups at 90, 120 and 180 days after surgery. CONCLUSION: The dimension of the healed areas of the defects treated with the biopolymer sugar-cane gel in the study group was similar to those of the control group, which healed naturally.

PURPOSE: To evaluate the influence of minoxidil, a well known vasodilator, on ischemic flap necrosis prevention in rats. METHODS: Ventral cutaneous flaps, measuring 8x4cm, were designed in 20 Wistar rats based on the right cranial epigastric artery. In the experiment group, 50 mg/kg/day of minoxidil sulfate was administered by orogastric tube and the same amount of saline solution was administered to the control group. Such procedure was initiated 24h before surgery and kept once a day through the 7th postoperative day. Microcirculation was evaluated with laser fluxometry 24h before surgical procedure, at immediate postoperative and at the 7th postoperative day. Flap necrosis area was evaluated by 2 methods: planimetry and weight/paper ratio. RESULTS: A significant flow increase in distal and medial extremity at M1 (medial point 1) (p=0,0484) was observed in the experiment group. There was significant difference in flap necrosis prevention in the experiment group (p=0,0433), although after necrosis took place there was no significant difference in necrosis size. (p=0,1051 and p=0,2799). CONCLUSION: Minoxidil sulfate is effective in avoiding necrosis in ischemic flaps, but after necrosis is present there is no difference in survival area between experimental and control groups.

Purpose. To evaluate the intima-media thickness (IMT) of the left and right common carotid arteries (CCA) as an indicator of subclinical atherosclerosis in patients with central serous chorioretinopathy (CSCR). Methods. This was a case-control study involving patients with CSCR and a matched healthy control group. The mean and difference of the left and right CCA IMT were determined and compared between the two groups using carotid duplex high-resolution B-mode ultrasound equipment. Results. The study enrolled 32 CSCR patients (68.8% female, mean age 38.22 ± 5.42 years) and 32 controls (65.6% female, mean age 39.56 ± 5.33 years). The difference in common carotid IMT between the right and left sides was significantly greater in the CSCR group than in the control group ( p < 0.001 ). Additionally, according to logistic regression analysis, patients with CSCR had a greater chance of having differences in IMT between the two sides when compared to the control group (OR: 1.29, 95% CI: 1.09–1.52). Conclusion. Our findings indicated that in the CSCR group, the difference between the right and left sides of CCA IMT was significantly greater than in the control group.

ABSTRACT Background: Elevated levels of chemerin can predict future ischemic cerebrovascular disease. Although chemerin is thought to play a role in atherosclerotic inflammation, whether circulating chemerin levels are associated with the severity of atherosclerosis remains to be determined. Objectives: Through the use of carotid Doppler ultrasonography, our aim in this study was to investigate the relationships of serum chemerin levels with carotid intima-media thickness (CIMT) as an indicator of generalized atherosclerosis. Methods: This study compared 40 patients with ischemic stroke and 40 healthy subjects. Measurements were made at end-diastole using color Doppler ultrasonography (CDUS) after a 5-min rest interval in a quiet and dark room. CIMT was defined as the distance between the innermost edge of the luminal echo to the innermost edge of the media/adventitia echo. CIMT was measured in the posterior wall of both common carotid arteries within 1 cm proximally to the bulbus. Three measurements were made on both sides and the average measurement was taken as the CIMT. Serum chemerin levels were determined in all patients and healthy subjects. Results: Serum chemerin levels were significantly higher in the patient group than in the control group (p=0.004). Serum chemerin levels were positively correlated with CIMT (p<0.05). There was a significant difference between the groups with regard to CIMT (p<0.001). Conclusion: Elevated serum chemerin levels appear to be associated with CIMT, thus suggesting that a link exists between chemerin and atherosclerotic ischemic cerebrovascular disease.

Objectives The objective of this study was to evaluate the diagnostic accuracy of infrared thermography in cats with acute pelvic paralysis to differentiate feline aortic thromboembolism (FATE) from non-ischaemic conditions. Methods Thermographic images were prospectively obtained at admission from cats presented for acute bilateral pelvic paralysis. Based on the final diagnosis, cats were divided into a FATE and a control group (ischaemic and non-ischaemic related pelvic paralysis, respectively). The maximum (Tmax), minimum (Tmin) and average (Tav) temperatures were determined for each of the four limbs within a hand-drawn region of interest on the dorsal limb extremity. Temperature differences between the forelimb (non-affected) and hindlimb (affected) with the highest temperature (ΔT), with the lowest temperature (δT) and from the right and left side (RightΔT and LeftΔT, respectively) were calculated. Results The FATE and control groups included 10 and six cats, respectively. In the FATE group, right hindlimb mean Tmax (23.6°C ± 1.9), left hindlimb mean Tmax (23.6°C ± 2.2) and mean Tav (22.7°C ± 2.2) were significantly lower than in the control group (26.6°C ± 3.5 [ P = 0.042]; 26.6°C ± 2.4°C [ P = 0.024] and 25.7°C ± 2.0 [ P = 0.020], respectively). ΔT, δT, RightΔT and LeftΔT were significantly higher in the FATE group than in the control group. A cut-off value of 2.4°C for RightΔTmax and LeftΔTmax allowed discrimination between the FATE and control groups with a sensitivity of 80% and 90%, respectively, a specificity of 100% for both, a positive predictive value of 100% for both, and a negative predictive value of 75% and 86%, respectively. Conclusions and relevance A minimal difference of 2.4°C between ipsilateral affected and non-affected limbs has an excellent specificity and high sensitivity for FATE diagnosis. Infrared thermography seems to be a promising, useful, easy, non-invasive and rapid method for detecting aortic thromboembolism in cats, particularly in emergency situations.
