Extracorporeal piezoelectric lithotripsy (PEL) with oral lysis (about 7.5 mg/kg urso- and chenodeoxycholic acid as single dose in the evening) was performed, according to a standardized treatment and follow-up protocol, in 219 patients (177 women, 42 men; aged 47 +/- 14 years) with symptoms of gallbladder stones. The average number of treatment sessions per patient was 2.0 +/- 0.8. Significantly fewer sessions with fewer shockwave charges were required in solitary gallstones of less than or equal to 20 mm diameter than in those of greater than 20 mm diameter and in multiple concrements (P less than 0.01). Fragmentation was successful in 99% of patients. Sedation and/or analgesia during PEL were required in only 2% of patients. There were no marked side effects during the treatment. The stone-free rate 12 months after the start of treatment was 76% in the group with solitary stones less than or equal to 20 mm, 75% with solitary stones greater than 20 mm and 64% for multiple stones. During the follow-up period 36% of patients had biliary colics and 3% had fragments impacted in the common bile duct. Biliary pancreatitis occurred in 1% of patients. PEL is an effective and sparing procedure in the treatment of selected patients with gallbladder stones.

Traditional centrally acting antihypertensives have been associated with a high incidence of adverse effects and are no longer recommended as first-line therapy. The newer imidazoline receptor agonists must overcome this reputation if they are to gain recognition as potential first-line agents for hypertension. Methyldopa, a centrally acting alpha(2)-agonist, is characterized by a number of serious adverse reactions that limit its use. Although unpredictable idiosyncratic or hypersensitivity reactions are uncommon, these include hepatitis, myocarditis, and hemolytic anaemia. Less serious problems such as abnormal liver function tests, positive Coombs test, drug-induced fever, and pancreatitis also occur. Central side effects include drowsiness, fatigue, lethargy, sedation, depression, psychotic reactions, nasal stuffiness, impotence, and exacerbation of Parkinsonism. In hypertensive men, methyldopa is less well tolerated than either captopril or propranolol, and up to 20% of patients discontinue therapy because of adverse effects. Clonidine acts primarily as an alpha(2)-agonist but also acts as an agonist at imidazoline receptors in the rostroventrolateral medulla. It is equipotent to most other antihypertensives but is considerably less well-tolerated in comparative trials. The principal adverse effects of clonidine are drowsiness, sedation, lethargy and dry mouth. Reserpine acts primarily by depleting central catecholamine neurotransmitter stores. It was very extensively used in early hypertension trials, but its central side effects of sedation, nasal stuffiness, and severe depression are now considered so undesirable that the drug is seldom prescribed. The imidazoline (I1) agonists moxonidine and rilmenidine act selectively and have very little central alpha(2)-agonist activity. In comparative studies against placebo and other reference antihypertensives, the only adverse effect consistently associated with these drugs was dry mouth (approximate placebo-corrected incidence 10%). Sedation was not pronounced. Withdrawal syndromes are complex pathophysiologic processes and occur with a variety of antihypertensive drugs. Cessation of therapy with clonidine and, to a lesser extent, methyldopa may result in a severe withdrawal syndrome characterized by restlessness, sweating, anxiety, tremor, palpitations, and headache. There may be a rapid rise in blood pressure, often with a true "rebound" to higher than pretreatment levels. Plasma and urinary catecholamine levels are increased, and fatalities have been reported. It is important to stress that such a syndrome has not been recorded, in animal or human studies, with either moxonidine or rilmenidine.

In critically ill patients, adequate sedation increases comfort, minimizes stress response and facilitates diagnostic and therapeutic procedures. Propofol (2-, 6-diisopropylphenol) is an intravenous sedative-hypnotic agent popular for sedation in the Intensive Care Unit. The favorable propofol pharmacokinetic, characterized by a three compartment linear model, allows rapid onset and short duration of action. The emergence time from sedation with propofol varies with the depth and the duration of sedation and the patient's bodyweight. Propofol causes hypotension, particularly in volume depleted patients, decreases cerebral oxygen consumption, reduces intracranial pressure and has potent anti-convulsant properties. It is a potent antioxidant, has anti-inflammatory properties and is a bronchodilator. As a consequence of these properties, propofol is being increasingly used in the management of traumatic head injury, status epilepticus, delirium tremens, status asthmaticus and in septic patients. Prolonged use (>48 h) of high doses of propofol (>66 mcg/Kg/min) has been associated with lactic acidosis, bradycardia, and lipidemia in pediatric patients. A rare complication firstly reported in pediatrics patients and also observed in adults is known as "propofol syndrome" characterized by myocardial failure, metabolic acidosis and rhabdomiolysis. Hyperkalemia and renal failure have also been associated with this syndrome. Hypertriglyceridemia and pancreatitis are uncommon complications. A large number of trials have compared the use of propofol with midazolam. Sedation with propofol is associated with adequate sedation in ICU patients, shorter weaning time and earlier tracheal extubation compared to midazolam, but not before ICU discharge.
