Fatigue and exercise intolerance are common symptoms of mitochondrial diseases, but difficult to be clinically assessed. New methods to quantify these rather common complaints are strongly needed in the clinical practice. Coenzyme Q10 administration and aerobic exercise may improve exercise intolerance, but more definite studies are still pending. Herein, we have revised "how to measure" and "h...

Daily low-dose acetylsalicylacid (ASA) is prescribed to patients with atherothrombosis frequently to prevent vascular complications. In reports on complications and side effects of low-dose ASA use in the literature there is a range of definitions. We explored the incidence, characteristics and consequences of symptoms suggestive of ASA intolerance in patients on low-dose ASA. General practitio...

In 35 asthmatic patients with acetylsalicylic acid (aspirin; ASA) intolerance (AIA) and 15 asthmatics tolerating ASA well, the authors compared the diagnostic value of the placebo-controlled oral ASA versus inhaled L-lysine (L) ASA challenges. All AIA subjects gave a history of asthmatic attacks following ingestion of ASA and in all of them the intolerance was confirmed by oral challenge test o...

Thirty-eight infants and young children with gastroenteritis were investigated for lactose malabsorption. Each of them was given an oral lactose load of either 0.5 g/kg or 2 g/kg after which breath hydrogen excretion was measured, and each was observed to see if he had clinical symptoms of lactose intolerance. Only one patient, given 2 g/kg lactose, had clinical intolerance. His breath hydrogen...

Salicylate intolerance is defined as a nonspecific antigen-induced pseudo-allergic hypersensitivity reaction which can occur upon contact of an organism with salicylic acid, its derivatives or other related organic or inorganic acids of similar chemical structure. Since the effects of nonsteroidal anti-inflammatory drugs (NSAID) intolerance are by no means always severe or life-endangering but ...

Many Michigan farm children are viewed as having suffered a deterioration in health coincident with contamination of dairy cattle by PBBs. Among Wisconsin dairy farm children such a deterioration was a rare event. There is a suggestion that Michigan farm children who had multiple symptoms during the 1973-76 period are getting better. A discrete syndrome of ill health has not been identified amo...

Full Text Tables and Figures References Patient-reported statin intolerance, predominantly due to statin-associated muscle symptoms (SAMS), is a common and difficult-to-manage condition affecting millions of patients worldwide. Different expert panels have proposed various definitions and classifications for statin intolerance. However, the development of SAMS does not necessarily signify stati...

BACKGROUND Irritable bowel syndrome (IBS) is a symptom-based disorder characterized by abdominal pain related to altered bowel habit. We evaluated the predictive power of 2 genetic markers of hypolactasia, C/T_13910 and G/A_22018, in IBS patients with and without lactose intolerance in order to gain insight into the role of lactose intolerance in IBS. METHODS Seventy five patients (59F/16M, m...
