All hospital records of patients who received a TPM at Aalborg Hospital, Denmark, between January 2000 and March 2011 (n = 575) were retrospectively reviewed. Patients with AV block who were treated with a TPM and concomitant cessation of drug therapy were included if there was no other underlying mechanism causing the AV block. AV blocking drugs included antiarrhythmic agents classes II-IV and digoxin. Fifty-five patients fulfilled our inclusion criteria. Forty-seven patients had an indication for a PPM at the initial hospital admission, despite drug discontinuation. Of the remaining 8 patients who were discharged without a PPM, 3 subsequently experienced events: 2 had recurrence of AV block requiring a PPM, and 1 experienced syncope. Thus, in total, 49 (89%) patients had a final indication for a permanent pacemaker (PPM). Of patients receiving beta-blocker monotherapy, 26 (96%) had an indication for a PPM. TPM implantation was complicated by infection or displacement in 11% of cases.

This study suggests that digoxin therapy may be of no benefit in patients with advanced HF referred for cardiac transplantation who received optimal medical therapy. Treatment with digoxin should be used cautiously in such patients because of risk for adverse outcomes.
Descriptive retrospective investigation.
Oligodendrocytes, the myelin-forming cells in the central nervous system, were visualized with excellent resolution at the light microscopic level using in situ hybridization (ISH). Digoxigenin (Dig)-tagged probes were synthesized and efficiently labeled by PCR. Specific probes to myelin genes were made by RT from brain total RNAs, followed by PCR with designed specific primers in the presence of Dig-11-dUTP. Probes specific to proteolipid protein (PLP), PLP and its isoform DM20 (PLP/DM20), and myelin oligodendrocyte glycoprotein (MOG) were synthesized and labeled. ISH was then applied on vibratomed tissue sections from mouse brains. Despite a low expression of MOG-specific and PLP-specific mRNAs in adult and newborn mouse brains, an oligodendrocyte population was detected. The specificity of Dig-labeled probes was confirmed with the double labeling of carbonic anhydrase II (CA II) and glial fibrillary acidic protein (GFAP) immunocytochemistry and ISH. This versatile and easy method for synthesis and labeling of specific probes to oligodendrocytes can be also applied to detect many other mRNAs in the nervous system and in other tissues.

The PT performance improved dramatically for the AOT group from 1994 through 2006 as measured by a decrease in the percentage of laboratories with unsatisfactory performance for 15 selected analytes. The PT performance in the HI group improved modestly for some analytes during this same period, whereas, for other analytes, the group showed no apparent improvement.

Familiar atrial fibrillation is a very infrequent arrythmia, usually well tolerated, that follows a dominant autosomic hereditary pattern. The use of antiagregants is advised because of the risk of embolism, or the use of anticoagulants in the presence of associated risk factors. Electric cardioversion has been show not be useful. The possible proarrythmic effect of some antiarrythmic agents, used in the control of cardiac frequency, must be taken into account.

Rate control remains the dominant strategy for treating new AF. The decrease in the use of oral antiarrhythmics may be due to lack of concrete data suggesting mortality and morbidity benefit as well as increasing use of the ablation approach.
Atrial fibrillation (AF) is common in ICU patients and is associated with a two- to fivefold increase in mortality. This paper provides a reappraisal of the management of AF with a special focus on critically ill patients with haemodynamic instability. AF can cause hypotension and heart failure with subsequent organ dysfunction. The underlying mechanisms are the loss of atrial contraction and the high ventricular rate. In unstable patients, sinus rhythm must be rapidly restored by synchronised electrical cardioversion (ECV). If pharmacological treatment is indicated, clinicians can choose between the rate control and the rhythm control strategy. The optimal substance should be selected depending on its potential adverse effects. A beta-1 antagonist with a very short half-life (e.g., esmolol) is an advantage for ICU patients because the effect of beta-blockade on cardiovascular stability is unpredictable in those patients. Amiodarone is commonly used in the ICU setting but has potentially severe cardiac and noncardiac side effects. Digoxin controls the ventricular response at rest, but its benefit decreases in the presence of adrenergic stress. Vernakalant converts new-onset AF to sinus rhythm in approximately 50% of patients, but data on its efficacy and safety in critically ill patients are lacking.
The advent of medical therapies for congestive heart failure that have proven survival benefits, specifically angiotensin-converting enzyme (ACE) inhibitors, beta-adrenergic antagonists, and the aldosterone antagonists, have called into question the use of digoxin for patients with normal sinus rhythm, left ventricular dysfunction, and symptomatic heart failure. This issue appears to have been heightened after the publication of the results of the Digitalis Investigation Group (DIG) Trial in 1997 that did not demonstrate a statistically significant impact of digoxin on mortality.

Evidence exists that demonstrates the relationship between a natriuretic factor, or Na+, K+-ATPase inhibitor, and volume expansion in man. Patients having extracellular volume expansion have been studied for the effect of their plasma on erythrocyte [3H]ouabain binding. High levels of ouabainlike activity were found in plasma from acromegalic patients and patients with chronic renal failure. High levels were also observed in some hypertensive patients. A partial purification of such a compound was performed from the urine of hypertensive patients. The various steps of purification achieved a 400,000-fold purified compound of apparent homogeneity. The inhibitor was extracted from 140 liters of urine of 21 donors (hypertensive patients and normotensive offspring of hypertensive patients). The purification steps included flash chromatography, anionic exchange, and reversed-phase HPLC on RP 18, diphenyl and phenyl packings. Nuclear magnetic resonance and mass spectrometry indicated a nonpeptidic compound, which was possibly a steroid with a low molecular mass (less than 500 daltons).

We report a brief description of the interaction profile of moxifloxacin. After oral administration, the absorption of moxifloxacin was unaffected by ranitidine or by food consumption. Drugs containing multivalent cations (e.g., Mg(++), Al(+++), and Fe(++), but not Ca(++)) impaired absorption. No clinically relevant effect of moxifloxacin was seen on the pharmacokinetics of digoxin under combination steady state conditions. Also, moxifloxacin did not affect the pharmacokinetics of theophylline or vice versa. This result, plus further data proving lack of interaction with glyburide, warfarin, and oral contraceptives, confirms the absence of metabolic interactions involving the cytochrome P-450 system, as previously reported. Concomitant administration of probenecid did not affect the elimination of moxifloxacin. Moxifloxacin thus has a unique drug interaction profile that is advantageous for its safe use.
Patients with abnormal HR response were more frequently without chest pain, with a history of chronic renal failure and taking digoxin. Baseline HR was higher and had fewer symptoms during stress. The stress and rest perfusion defects were greater, but reversibility was not; in addition, LVEF was lower. Multivariable logistic regression analysis demonstrated that the independent predictors of abnormal HR response were baseline HR and low LVEF.
