Among the symptoms that may occur with smoking withdrawal, constipation is relatively frequent, but little studied. ⋯ This constipation sometimes produces serious functional disorders and can induce relapse. It occurs especially among women and those predisposed to it. Nicotine, by acting on the parasympathomimetic system, increases intestinal peristalsis, and a cigarette can appear to be effective self-medication. Magnesium salts are the first-line treatment for this problem. If they fail, neostigmine, an anticholinesterase with parasympathomimetic activity, appears remarkably effective in correcting this disorder.

Review Comparative Study
[Statins in patients with kidney failure: efficacy, tolerance, and prescription guidelines in patients with chronic kidney disease and renal transplant].
Chronic kidney disease (CKD) is extremely common in adults, although often undiagnosed and thus untreated. Cardiovascular disease is the leading cause of death among patients with CKD and reducing its risk in this population is an important priority. Dyslipidemia is almost always present when proteinuria is above 3 gr/24 hours. Roughly two thirds of all patients with end-stage renal failure and kidney transplants suffer from dyslipidemia and should receive lipid-lowering therapy, as suggested by recent Afssaps (French drug agency) and NKF-K/DOQI (National Kidney Foundation-Kidney Disease Outcomes Quality Initiative) guidelines. We reviewed recent studies on efficacy, tolerability and prescription recommendations of statins in CKD and renal transplant patients. ⋯ Statins at appropriately adapted doses have the same efficacy in CKD patients as in subjects with normal kidney function, and tolerance is not a problem. Their effectiveness in cardiovascular prevention in this population has not been demonstrated to date. Results about statin-induced kidney protection are encouraging but further and more specific studies are needed.
