Background: Tension-type headache (TTH), the most frequently occurring primary headache is associated with autonomic dysfunction. Time domain analysis of heart rate variability (HRV) is a popular tool to detect changes in cardiac autonomic nerve function (CANF) in TTH patients. Slow breathing exercise (SBE) can significantly improve HRV in patients with cardiovascular disorders. Objective: To observe the effect of SBE on HRV by time domain analysis in TTH female patients. Methods: This quasi-experimental study was conducted from March 2021 to February 2022 in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka on 60 female TTH patients aged 20-45 years. Thirty patients performed SBE every morning and evening for 30 minutes in addition to receiving conventional treatment and 30 patients continued only conventional treatment without any exercise for 90 days. Thirty age, sex and BMI matched apparently healthy control were enrolled who did not perform SBE or any other exercise. All subjects were assessed at baseline and also after 90 days. Time domain HRV parameters were recorded by Power Lab 8/35 AD Instruments, Australia. One way ANOVA followed by post-hoc test and Paired sample t-test were performed for statistical analysis and p<0.05 was considered as statistical significance. Results: Mean heart rate (HR) was significantly higher (p<0.001) and SDRR (Standard deviation of all RR interval); CVRR (Coefficient variation of RR interval); SDSD (Standard deviation of successive RR interval differences between adjacent RR intervals); RMSSD (Square root of mean of squared differences of successive RR interval) and pRR50% (Proportion of RR interval with duration > 50ms) were significantly lower (p<0.001) in TTH female patients compared to control at baseline. Significant decrement of mean HR (p<0.001) and increment of all other time domain parameters (p<0.001) was observed after 90 days of SBE. Again, significantly decreased SDRR, CVRR, SDSD, RMSSD and pRR50% (p<0.001, p<0.01) was observed in the patients who did not perform SBE. Conclusion: SBE may effectively improve cardiac autonomic dysfunction in TTH female patients. J Bangladesh Soc Physiol. 2022, June; 17(1): 56-63
A 7-year-old boy was referred to the department of conservative dentistry and endodontics, Bangabandhu Sheikh Mujib Medial University (BSMMU) with pain on his left lower jaw. After clinical and radiological examination, it was diagnosed as a case of reversible pulpitis. Biodentine pulpotomy was performed followed by permanent restoration with glass-ionomer. The presented case was done to evaluate the efficacy of Biodentine as pulpotomy medicament in primary molar teeth, on follow-up it was found to be successful.Birdem Med J 2017; 7(3): 238-241
Cerebral venous sinus thrombosis is an uncommon but important cause of stroke, especially in young-aged woman. Clinical presentation is variable, usually in the form of focal neurological deficit, seizure, headache and other features of raised intracranial pressure, leading to misdiagnosis or delay in treatment. Here we report 4 cases of venous sinus thrombosis with variable presentation. Diagnosis is confirmed by neuroimaging including magnetic resonance imaging with magnetic resonance venography of brain. Treatment consists of anticoagulation along with supportive management. Bangladesh Journal of Neuroscience 2017; Vol. 33 (1): 30-33
Neurological features of severe hypoglycemia range from reversible focal deficits to irreversible coma or death. Diffusion weighted MRI of brain image is a useful tool in evaluating profound hypoglycemic brain injuries. We report a case of 27 year old male who died from brain injuries following an episode of prolonged hypoglycemia. We here discuss the neuropathological and diffusion-MRI changes of hypoglycemic brain injuries and its prognostic importance. Bangladesh Journal of Neuroscience 2013; Vol. 29 (1) : 60-63
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
