Transcranial Doppler (TCD) sonography is emerging as a new ultrasonography technology to look at the interaction between the brain parenchyma and perfusion during cerebrovascular accident. Before TCD sonography the vasospasm following subarachnoid haemorrhage could only be diagnosed either clinically or by invasive method ie, angiography. TCD has been proved as a wonderful non-invasive, repeatable, beat-by-beat, non-expensive technique for detection and follow-up of vasospasm after subarachnoid haemorrhage. ⋯ Most of the patients were clinically presented with increasing headache and altered sensorium. It is noticed that vasospasm following subarachnoid haemorrhage has a typical course, which has increasing trend after 4th day of subarachnoid haemorrhage and declining trend after 14th day onwards. Six out of 12 patients were in moderate grade of vasospasm, 2 out of 12 were in severe grade and 4 out of 12 were mild grade of severity.

Randomized Controlled Trial Clinical Trial
Ondansetron in prophylaxis of postoperative nausea and vomiting in patients undergoing breast surgery: a placebo-controlled double blind study.
The present study was to evaluate the efficacy of ondansetron, 5-HT3 receptor antagonist, versus placebo in the prevention of postoperative nausea and vomiting (PONV) in a homogenous group of female patients undergoing breast reduction surgery under general anaesthesia. Approximately one hour before skin closure, 70 patients were randomly divided into two groups of 35 each. In a double blind manner each group of patients received either intravenous ondansetron (4mg) or a matching placebo. ⋯ However, there was no significant difference after 24-hour postoperatively. In placebo group 42.9% of patients received rescue anti-emetic (metoclopramide) for the treatment of severe PONV (ie, 2 or more episodes of PONV), whereas, only 8.6% patients were administered such intervention in the ondansetron group (p<0.05). It is, therefore, concluded that prophylactic administration of intravenous ondansetron (4mg) one hour before skin closure is safe and effective in preventing PONV in female patients undergoing breast surgery and routine use of ondansetron in the patient population is recommended.

Muscle weakness, stiffness and delayed tendon jerk relaxation are usual features of hypothyroidism while muscle hypertrophy, myoedema and wasting are occasionally seen. A 60-year-old male, who presented with proximal muscle weakness and muscle hypertrophy has been reported here. Thyroid function tests, electromyogram and muscle biopsy established the diagnosis of thyroid myopathy with Hoffman's syndrome.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of ondansetron, dexamethasone, ondansetron plus dexamethasone and placebo in the prevention of nausea and vomiting after laparoscopic tubal ligation.
Laparoscopic tubal ligation is associated with an appreciably high rate of postoperative nausea and vomiting. This study was designed to compare the effectiveness of ondansetron, dexamethasone, ondansetron plus dexamethasone or placebo in the prevention of postoperative nausea and vomiting in patients after laparoscopic tubal ligation. In a prospective, randomised, double blind placebo controlled trial, 160 ASA I-II females received one of four regimens; ondansetron 4 mg, dexamethasone 8 mg, ondansetron 4 mg plus dexamethasone 8 mg or placebo (n=40 each) intravenously immediately before induction of anaesthesia. ⋯ The incidence of emetic episodes in the ondansetron with dexamethasone group was lower than in the placebo (p<0.001) and ondansetron (p=0.091) and dexamethasone (p=0.143) groups. A complete response (as no postoperative nausea and vomiting) was achieved in 60% of patients given ondansetron, 63% of the patients given dexamethasone, 78% of patients given ondansetron with dexamethasone and 37% of patients received placebo. The prophylactic use of ondansetron with dexamethasone is more effective in preventing postoperative nausea and vomiting.
