Iron overload in animal models and humans increases oxidative stress and induces cardiomyopathy. It has been suggested that the vasculature is also damaged, but the impacts on vascular reactivity and the underlying mechanisms remain poorly understood. In this study, we aimed to identify possible changes in the vascular reactivity of aortas from iron overloaded rats and investigate the underlying mechanisms.

About 25% of patients with Kelley-Seegmiller syndrome present mild neurological symptoms but never with self-destructive behavior. Pathophysiological an increased de novo purinsynthesis is present. Therefore, it comes to an overproduction of urine acid. Urolithiasis is one clinical manifestation.

Between 1972 and 1985, 87 patients with toxic epidermal necrolysis (TEN) were admitted to the dermatological intensive care unit at Hôpital Henri Mondor, Créteil, France. The culpable drug was determined by standardized criteria. Only three patients had received no drugs before the onset of TEN. Most patients (71 of 87) were receiving more than one drug. Patients had taken an average of 4.4 +/- 3.4 drugs each. A culpable drug was determined in 67 patients (77%). The mean time from first drug administration to onset of TEN was 13.6 +/- 8.4 days. The culprit drugs included the following: sulfonamides, 18 cases, and especially sulfamethoxazole and trimethoprim, 12; anticonvulsants, seven (barbiturates and carbamazepine only); nonsteroidal anti-inflammatory drugs, 29 (especially the phenylbutazone derivative, 16, and oxicam derivatives, 10); allopurinol, three; chlormezanone, three; and others, seven. Aspirin, antipyretics, and antibiotics are infrequently implicated in this series. The pattern of culprit drugs changed with years. The level of sulfonamide-related TEN remained the same, while incidence of nonsteroidal anti-inflammatory drug-induced TEN increased sharply, the introduction of oxicam derivatives being in part responsible.

Of the 29,298 episodes of incident allopurinol use, 1544 were associated with incident MI (5.3 % episodes). Allopurinol use was associated with reduced hazards of MI, with a HR of 0.85 (95 % CI, 0.77 to 0.95). Compared to no allopurinol use, longer durations of allopurinol use were associated with a lower HR of MI: 1-180 days, 0.98 (95 % CI, 0.84 to 1.14); 181 days to 2 years, 0.83 (95 % CI, 0.72 to 0.95); and >2 years, 0.70 (95 % CI, 0.56 to 0.88). Other factors associated with a higher hazard of MI were: age 75 to <85 years and ≥85 years, male gender, higher Charlson index score, and the use of an ACE inhibitor. Adjustment for CAD risk factors confirmed these findings.

Two cases of cephalosporin-induced hepatotoxicity with associated jaundice are presented. Both patients developed jaundice and liver enzyme abnormalities soon after injectable cephalosporin therapy was started. Other possible causes were ruled out, including TPN and allopurinol hepatoxicity, and additional medical illnesses associated with hepatoxicity. Both patients recovered fully from the episode of jaundice. Review of the literature suggests a possible hypersensitivity reaction similar to liver toxicity of the penicillin antibiotics.

In previous studies, we have shown that the rate of cell swelling induced by concentrative proline uptake in isolated rat hepatocytes decreased by 50 per cent after only 24 h of cold storage in University of Wisconsin (UW) solution, thereby representing a sensitive marker of alterations in hepatocyte functions after cold preservation and rewarming. We have thus used concentrative proline uptake to compare the capacity of UW and sodium-lactobionate-sucrose (SLS) solutions to maintain such differentiated hepatocyte functions. Isolated rat hepatocytes were kept at 4 degrees C for 4, 10, 24 and 48 h in UW or SLS solutions, and subsequently cultured at 37 degrees C for 1-2 h. Viability was measured by Trypan blue exclusion. After rewarming, cells were subjected to a 10 min administration of 10 mM proline and accumulation of the amino acid was assessed by changes in cell volume as measured by digital analysis of single-cell images obtained under bright-field illumination. Cell viability was reduced gradually and significantly after 0 to 48 h of preservation, and rewarming amplified this effect. However, loss of viability was similar in UW- and SLS-stored cells, as were initial steady-state cell volumes. Proline-induced swelling rate was reduced significantly by 13, 46 and by 57 per cent after 10, 24 and 48 h of preservation in UW solution, respectively. There is no significant difference between SLS- and UW-preserved hepatocyte swelling rates after 10 h and 48 h of cold preservation. However, the decline in the swelling rate of SLS-preserved hepatocytes incubated for 24 h is significantly lower than that of their UW-preserved counterparts. These results show that the SLS solution can preserve differentiated hepatic functions as well as the UW solution does.

Gout, a common inflammatory arthritis, can be diagnosed with absolute certainty. Gout results from the body's reaction to urate crystals deposited in tissues, and this pathophysiology is well understood. If used appropriately, available therapies can be entirely effective in not only treating the symptoms of gout, but also in eliminating the excess urate from the body, thereby eradicating the disease. Because of these facts, management of patients with gout should be successful. However, management of gout is particularly challenging in the elderly, even though the principles of management are the same for all age groups. The purpose of this article is to review these principles and discuss them as they pertain to the elderly. The classic gout attack is acute in onset, extremely painful and associated with marked swelling, warmth, erythema and tenderness of a single joint. However, the diagnosis of gout may be challenging in the elderly because atypical presentations are more common in this group. Treatment of acute gout involves the use of NSAIDs, colchicine, corticosteroids or corticotropin (adrenocorticotropic hormone). Unfortunately, co-morbid conditions such as chronic kidney disease, peptic ulcer disease and congestive heart failure may make the use of these agents dangerous or contraindicated. Thus, it is important to try to treat an acute flare of gout at the earliest sign, because the sooner treatment is initiated, the faster the inflammation will resolve. Urate-lowering agents include allopurinol and uricosuric agents. These also must be used judiciously in the elderly. However, if used at the lowest dose that maintains the serum urate level below 5.0-6.0 mg/dL, the excess urate in the body will be eliminated, acute flares will no longer occur and tophi will resolve. Gout is often seen in association with hypertension, excessive alcohol consumption, obesity and hypertriglyceridaemia. These conditions and the medications used to treat them may contribute to the hyperuricaemia. Treating these conditions and using medications that do not promote hyperuricaemia will aid in the management of gout. Despite the challenges that often complicate the management of gout in the elderly, an understanding of the pathophysiology of the disease and both the indications and limitations of the medications used should allow successful treatment.

An important aspect of organ preservation is the maintenance of intrinsic dilator and antithrombotic mechanisms of blood vessels. Blood vessels synthesize prostacyclin (PGI2), a potent vasodilator and inhibitor of platelet adhesion and aggregation. PGI2 synthesis is controlled by complex mechanisms including adrenoceptor-linked calcium influx and protein kinase C. Since organ preservation solutions may influence these mechanisms, we investigated the effect on in vitro PGI2 synthesis of cold storage of rat aortic rings in lactobionate-raffinose solution (LRS) and hypertonic citrate kidney preservation solution (KPS) on in vitro PGI2 synthesis. Acute incubation of aortic tissue in both preservation solutions at 37 degrees C (compared with minimal essential medium) completely inhibited PGI2 synthesis when stimulated with noradrenaline (NA), phorbol ester (a protein kinase C activator), NaF (a G protein activator), or A23187. Following storage of aortic rings at 4 degrees C (for up to 72 hr) in LRS and KPS, subsequent washing and incubation in MEM, PGI2 synthesis was initially markedly enhanced in response to NA when compared with tissues stored in MEM. These enhanced responses disappeared, and PGI2 synthesis returned to normal following 1 hr incubation of tissues in MEM at 37 degrees C. These data demonstrate that cold storage in preservation fluids exerts minimal deleterious effects, not only on PGI2 synthesis, but possibly on other key processes (calcium homeostasis, protein kinase C activity) in blood vessels.
