Exteroceptive suppression (ES) periods in human jaw-closing muscles can be conditioned by a wide range of somatosensory stimuli and cognitive states. The aim of this study was to examine the effects of subanaesthetic doses of midazolam, ketamine and propofol on the short latency (ES1) and long latency (ES2) reflex in the jaw-closing muscles. First, we tried to evaluate the various methodological criteria for ES recording. We then examined the effect of subanaesthetic doses of midazolam (0·035 mg kg(-1)), ketamine (0·30 mg kg(-1)) and propofol (0·35 mg kg(-1)) on these reflexes of recording left masseter and temporalis muscle. ES duration did not differ greatly in the present study, recorded with the correct adjustment of stimulating and recording conditions. None of the subanaesthetic doses of the agents influenced ES1, and no significant effects on ES2 were observed with midazolam and ketamine. However, significant inhibitory change was observed in ES2 with propofol. ES2 is thought to be mediated by afferents, which descend in the spinal trigeminal tract and connect with a polysynaptic chain of excitatory interneurones located in the lateral reticular formation. Our observations indicate that propofol is uniquely effective not only through involvement of the gamma-aminobutyric acid type A receptor, but also through a range of other effects.
Background: Bangladesh recently became a middle income country and despite of its relatively low skilled birth attendance (26.5%) nevertheless experience a rise in caesarean section (CS) rate. But now the rate of CS increased almost seven fold from 3.5% in 2004 to 23% in 2016.
Objective: To find out the cause and incidence of caesarean section among the primigravid mother in Rajshahi medical college hospital performed in between January 2017 to December 2017.
Methods: This prospective type of observational study was performed in Rajshahi Medical College Hospital (RMCH) over a period of one year from January 2017 to December 2017. All primigravida who underwent caesarean section in RMCH were included.
Result: During the study period there were 11018 deliveries. Overall CS rate was 40.98%. The rate in primi was 30.70% and last year it was 25.58%. Conclusion: The vast majority of CS was not medically indicated. A number of policies and program had been launched to counteract this increasing rate of CS but virtually there was no impact.

A 50 day old Non-Descriptive puppy weighing 0.9 kg was brought to the hospital, for evaluation of regurgitation of 6 day. The puppy began regurgitating 6 days before at the time of weaning to solid food. The puppy was thin, underweight and had distended abdomen, contrast radiograph revealed megaoesophagus and constriction of the oesophagus at the base of the heart and the condition was diagnosed as Persistent Right Aortic Arch (PRAA). Left lateral thoracotomy was performed and PRAA was surgically corrected. Long term follow-up for 6 months was conducted, pet recovered uneventfully.
Vesicouterine fistula (VUF) is a very rare occurrence and is estimated to occur in only (1-4%) of all genitourinary fistulas. It is an abnormal pathway between the bladder and the uterus. The most common cause is lower segment caesarean section. Patients usually present in the early post operative period with the problem of continuous urinary incontinence. On the rare occasion, recurrent urinary tract infection, recurrent gross painless haematuria, or secondary infertility associated with secondary amenorrhoea would be the presenting complaint. Among all vesicouterine fistula 90% are Youseef’s Syndrome the least common of the urogynaecological fistulas. Youseef’s syndrome is characterized by cyclic haematuria (menouria), absence of vaginal bleeding (amenorrhea) and urinary incontinence due to vesicouterine fistula (VUF).TAJ 2017; 30(1): 70-72
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.
