We introduced a simple technique to eliminate electromagnetic interference between a left ventricular assist device (LVAD) and an implantable cardioverter defibrillator (ICD). A 43-year-old male with heart failure and a reduced ejection fraction who had an ICD presented with decompensated heart failure and received an LVAD as a bridge to transplant. Remote monitoring showed persistent atrial fibrillation causing an inappropriate ICD shock leading to a decision to disable shock therapies. However, an in-office interrogation was unsuccessful due to electromagnetic interference. Patient was instructed to extend his arm above his head on the ipsilateral side of the ICD, thus increasing the distance between LVAD and ICD, eliminating the interaction to allow reprogramming of the device. 相似文献

Maple Syrup Urine Disease (MSUD) is an autossomal recessive metabolic disorder caused by a deficiency of branched-chain α-keto
acid dehydrogenase complex activity leading to accumulation of the branched-chain amino acids leucine, isoleucine and valine
and their corresponding branched-chain α-keto acids. Affected patients usually present hypoglycemia, ketoacidosis, convulsions,
poor feeding, coma, psychomotor delay and mental retardation. Considering that the pathophysiology of MSUD is still poorly
understood, in this study we evaluated some parameters of oxidative stress, namely thiobarbituric acid-reactive substances
(TBARS), total antioxidant reactivity (TAR) and total antioxidant status (TAS) in plasma from treated MSUD patients presenting
high and low plasma leucine levels. We verified a significant increase of TBARS (lipid peroxidation) and a decrease of TAR
(capacity to rapidly react with free radicals) in plasma from treated MSUD patients with low and with high plasma levels of
leucine compared to the control group. It was also verified that TAS (quantity of tissue antioxidants) was not altered in
plasma from treated MSUD patients with low and high blood leucine levels. Finally, we found no correlation between leucine,
valine and isoleucine levels with the various parameters of oxidative stress. These results are indicative that increased
lipid oxidative damage and decreased antioxidant defenses occur in plasma of MSUD patients and that the accumulating branched-chain
amino acids are probably not directly associated to oxidative stress in this disorder. 相似文献

Using ubiquitous primers which amplify the variable parts of kDNA minicircle of all Leishmania spp, we obtained for Leishmania (viannia) lainsoni a major band of 605 bp (band 1) shared with L. V. braziliensis and a minor 524 bp band (band 2) specific of L. V. lainsoni. The specificity of the two bands was examined through Southern blot hybridization of kDNA PCR obtained from reference strains belonging to L. braziliensis, L. mexicana, L. donovani complexes with L. V. lainsoni species. Band 1 was not specific of L. V. lainsoni since it hybridized with some isolates belonging to L. braziliensis complex. In contrast, band 2 was L. V. lainsoni specific. PCR-based detection followed by hybridization with the new L. V. lainsoni probe (Band 2) and L. V. braziliensis probe (564 bp), was assayed using sample from a pool of 25 females of Lutzomiya nuneztovari anglesi, blood, skin and liver samples of 18 mammals, spinal cords of four mammals and blood and cutaneous ulcers aspirates from 95 patents from Sub Andean region of La Paz, Bolivia. We observed a ositive hybridization of four patients lesions and the pool of L. nuneztovari anglesi with the L. V. lainsoni probe. It is the first time that L. V. lainsoni is observed in a cycle of transmission in Bolivia. PCR products of three patients lesions and the pool of L. nuneztovari anglesi were also hybridized with the specific probe of L. V. braziliensis suggesting mixed infection in this focus. 相似文献

Coronary Venous Ablation of VT. Ventricular tachycardias in coronary artery disease arise mostly from endocardial sites. However, little is known about the site of origin in other diseases. We present the case of an incessant, adenosine-sensitive ventricular tachycardia arising from the lateral wall of the left ventricle in a patient with mildly reduced left ventricular function. Intracardiac mapping suggested an epicardial origin, and the tachycardia was successfully ablated from a coronary sinus branch. After ablation, left ventricular function returned to normal. Transcoronary venous radiofrequency catheter ablation is a new approach for the treatment of ventricular tachycardia. Its value in the management of other types of ventricular tachycardia has yet to he determined. 相似文献

We designed and evaluated a program to teach internal medicine residents behavioral counseling skills for multiple risk factor modification. Integrating physician-patient communication, negotiation skills, and the transtheoretical model of behavior change, we used small group discussion and standardized patients. The 18 participating residents increased their ability to modify patient behavior during videotaped interviews, mean pretest/posttest score: 33.1/40.1 (Student’s pairedt test, p<.0001). Physician self-efficacy in screening for risk factors and effecting behavioral change in patients was increased (p<.0001), as were positive attitudes toward psychosocial factors (p<.003). Our teaching effectively increased the residents’ self-efficacy and performance of behavioral counseling. 相似文献
