Thyrotoxic periodic paralysis in a Caucasian man in treatment for Graves' disease.

Thyrotoxic periodic paralysis (TPP) is the main secondary form of hypokalemic periodic paralysis and is mostly associated with Graves' disease. Initially diagnosed in Asian countries, TPP has been sporadically reported in different populations of the Western World. Increased Na+/K(+)-ATPase activity seems to be responsible for the marked hypokalemia observed during the transient paralysis attacks.

Early acute cellular rejection: no effect on late hepatic allograft function in man.

Whereas early acute cellular rejection, even if successfully treated, seems to have an impact on late function and survival of kidney and heart transplants, little quantitative data are available on its effect(s) on liver transplants. Routine liver function tests, the functioning liver cell mass (galactose elimination capacity) and microsomal metabolic capacity (aminopyrine breath test) were determined prospectively in 37 consecutive patients 1 year after liver transplantation. Of these, 19 (7 females and 12 males, 32-69 years of age) had previously required treatment for at least one biopsy proven acute cellular rejection episode occuring a median 7 days after grafting, while 18 (6 females and 12 males, 30-67 years of age) had not.

Gastric and intestinal ethanol toxicity in the rat. Effect on glutathione level and role of alcohol and acetaldehyde metabolisms.

Background/aims: This study investigated the dose- and time-dependent effect of ethanol on gastric and intestinal glutathione and protein oxidative state in the rat.

Methods: Rats received 1 or 4 g/kg of 25% ethanol solution orally or isocaloric glucose. Some rats received diethylmaleate, cimetidine or cyanamide before ethanol (1 g/kg).

Nursing role innovations: improved outcomes in a trauma center.

Trauma systems operate on the principle that people with severe injuries require special medical capabilities if they are to have their best chance of recovery. However, optimal trauma care is threatened by the problems of inadequate financial reimbursement. This threatens the ability to deliver trauma patient care.

Oxidative modification of proteins in chronic alcoholics.

Oxidative modification of proteins is of great importance because of their biological role in transport, enzyme activity, immune response and membrane fluidity. This study investigated the redox status of proteins in plasma, erythrocyte and erythrocyte ghosts of chronic alcoholics; a comparison with subjects affected by chronic viral hepatitis and healthy controls was also performed. Compared to the other groups, chronic active alcoholics showed significant increase of plasma, erythrocyte and erythrocyte ghost concentrations of carbonyl proteins, marker of protein oxidative damage.
