Abstract Objectives This study aimed to evaluate serum otolin-1 levels in patients with benign paroxysmal positional vertigo and to compare these levels with healthy individuals. Method This was a case-control study. After obtaining institutional ethical committee clearance, the serum level of otolin-1 was calculated in adult individuals (18–75 years old) who were divided into group 1 (patients presenting with benign paroxysmal positional vertigo) and group 2 (healthy patients without benign paroxysmal positional vertigo as the control group). Data analysis was carried out to compare the serum levels in the cases and controls. A p-value less than 0.05 was considered significant. Results A total of 70 age-matched individuals (cases, n = 40; controls, n = 30) were included in the study. The mean serum level of otolin-1 was 636.8 pg/ml (range, 259–981 pg/ml) in the group of patients with benign paroxysmal positional vertigo and 236.2 pg/ml (range, 189–370 pg/ml) in the control group. The difference was statistically significant (p = 0.0000). Conclusion The serum levels of otolin-1 in patients with benign paroxysmal positional vertigo are significantly higher compared with individuals without benign paroxysmal positional vertigo.

Objective: The present case-control study was undertaken to find the association between serum level of CRP and attack of migraine. Methods: The study was carried out at the Headache Clinic and Outpatient Department of Neurology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka over a period of 2 years from January 2010 to December 2011. Migraine patients attending at the above mentioned places were enrolled as cases, while apparently healthy attendants of cases and other healthy persons, who did not have any history of migraine, were included as control. Based on predefined enrollment criteria, a total of 163 subjects were included in the study. Of them 87 were cases and 76 were controls. The serum levels of CRP of both cases and controls were measured and a serum level of > 6 mg/L was considered as raised/ elevated CRP. Levels of CRP were compared between groups (case and control) using appropriate statistical tests. Result: The findings of the study showed that the age and sex distribution of case and control groups were almost comparable. The behavioral factors like food or smoking habit and tobacco leaf chewing had no difference between the groups. Over 20% of migraine patients had abnormally high CRP as compared to 7.9% in the control group (p = 0.021). The migraine patients were 3(95% CI = 1.1 - 8.1) times more likely to be associated with raised CRP (> 6 mg/L) than their healthy counterparts. There were 7 migraine patients with aura and 80 without aura. The level of CRP was not found to be associated with type of migraine (with or without aura) (p = 0.960). Conclusion: Every one in five patients exhibits abnormally high CRP. The level of CRP does not vary whether the migraine is being associated with or without aura. The migraineurs carry higher risk of developing elevated CRP than their normal counterparts. Bangladesh Journal of Neuroscience 2015; Vol. 31 (1): 1-8

Abstract Objective: To investigate the possible role of superoxide dismutases (SODs) in the development of benign paroxysmal positional vertigo (BPPV) and recurrence events in a 1-year follow-up study. Methods: This was a prospective one-center study. A total of 204 patients with BPPV and 120 age-and sex matched healthy subjects were included. The levels of SOD between patients and control cases were compared. The levels of SOD between posterior semicircular canal (PSC) and horizontal semicircular canal (HSC) were also compared. In the 1-year follow-up, recurrence events were confirmed. The influence of SOD levels on BPPV and recurrent BPPV were performed by binary logistic regression analysis. Results: The serum levels of SOD in patients with BPPV were lower than in those control cases (P<0.001). Levels of SOD did not differ in patients with PSC and HSC (P=0.42). As a categorical variable, for per interquartile range (IQR) increment of serum level of SOD, the unadjusted and adjusted risks of BPPV would be decreased by 72% (with the odds ratio [OR] of 0.28 [95% confidence interval (CI): 0.21–0.37], P<0.001) and 43% (0.57 [0.42–0.69], P<0.001), respectively. Recurrent attacks of BPPV were reported in 50 patients (24.5%). Patients with recurrent BPPV had lower levels of SOD than in patients without (P<0.001). For per IQR increment of serum level of SOD, the unadjusted and adjusted risks of BPPV would be decreased by 51% (with the OR of 0.49 [95% CI: 0.36–0.68], P<0.001) and 24% (0.76 [0.60–0.83], P<0.001), respectively. Conclusion: Reduced serum levels of SOD were associated with higher risk of BPPV and BPPV recurrence events.

AbstractThis study was aimed to investigate the role of anatomic variations in patellofemoral alignment in patients with or without Osgood-Schlatter disease (OSD) and to determine the potential anatomic risk factors that may play role in the etiology. This prospective observational case-control study was conducted on two groups of adolescent patients. Group 1 comprised patients who were diagnosed as having OSD and group 2 consisted of an equal number of age-matched patients who presented to the outpatient clinic with traumatic knee injury and underwent knee radiographic examination but without a diagnosis of OSD. Age, height, weight, body mass index (BMI), dominant side, and level of sporting activity were recorded. Quadriceps (Q) angles were measured using a long-arm goniometer with patients lying in the supine position with their knees in full extension and contracting the Q muscles. On anteroposterior, lateral knee, and tangential patella (Merchant and Laurin views) radiographs, the following measurements were performed: Insall–Salvati (IS), Caton–Deschamps (CD), and Blackburne–Peel (BP) indexes, congruence angles, lateral patellofemoral angles, sulcus angles, and patella type according to Grelsamer's morphology classification. Both groups were similar in respect of age (p = 0.160), sex (p = 0.311), height (p = 0.326), weight (p = 0.596), BMI (p = 0.153), and dominancy (p = 0.500). The rate of patients engaged in sports activities was significantly greater in the OSD group (p = 0.003). No significant difference was determined between the groups in respect to IS index, CD index, BP index, sulcus angle, lateral patellofemoral angle, and congruence angle (p–values: 0.358, 0.995, 0.912, 0.802, 1.000, and 0.907, respectively). The mean Q angle was measured as 15.6 ± 2.2 degrees in the OSD group and 14.3 ± 2.5 degrees in the control group (p = 0.014). Despite the difference being statistically significant, it was clinically insignificant because the difference was only 1.3 degrees. The principle etiologic factor seems to be increased physical activity rather than subtle variations is patellofemoral anatomy and alignment of extensor mechanism.
