[source] Oxford experience with neoadjuvant chemotherapy and surgical resection for esophageal adenocarcinomas and squamous cell tumorsDISEASES OF THE ESOPHAGUS, Issue 3 2008P. M. Safranek SUMMARY., The Medical Research Council trial for oesophageal cancer (OEO2) trial demonstrated a clear survival benefit from neoadjuvant chemotherapy in resectable esophageal carcinoma. Since February 2000 it has been our practice to offer this chemotherapy regime to patients with T2 and T3 or T1N1 tumors. We analyzed prospectively collected data of patients who received neoadjuvant chemotherapy prior to esophageal resection under the care of a single surgeon. Complications of treatment and overall outcomes were evaluated. A total of 194 patients had cisplatin and 5-fluorouracil prior to esophageal resection. Six patients (5.7%) had progressive disease and were inoperable (discovered in four at surgery). During chemotherapy one patient died and one perforated (operated immediately). Complications including severe neutropenia, coronary artery spasm, renal impairment and pulmonary edema led to the premature cessation of chemotherapy in 12 patients (6.2%). A total of 182 patients with a median age of 63 (range 30,80), 41 squamous and 141 adenocarcinomas underwent surgery. Operations were 91 left thoracoabdominal (50%), 45 radical transhiatal (25%), 40 Ivor-Lewis (22%) and six stage three (3%), and 78.6% had microscopically complete (R0) resections. Median survival was 28 months with 77.3% surviving for 1 year and 57.7% for 2 year. In hospital mortality was 5.5% and anastomotic leak rate 7.7%. A radical surgical approach to the primary tumor in combination with OEO2 neoadjuvant chemotherapy has led to a high R0 resection rate and good survival with acceptable morbidity and mortality. [source] Cardiac arrest related to coronary spasm in patients with variant angina: a three-case studyJOURNAL OF INTERNAL MEDICINE, Issue 4 2002W. Seniuk We present three patients with variant angina pectoris and episodes of cardiac arrest. All of them had typical clinical symptoms, ST-segment changes in electrocardiogram, and coronary artery spasm confirmed by arteriography. They were treated with high doses of calcium antagonists and nitrates. An automatic cardioverter-defibrillator was implanted in the patient who developed ventricular fibrillation despite therapy with calcium antagonists. In another patient a DDD pacemaker was implanted because of high-degree atrioventricular block. [source] Subcutaneous administration of nitroglycerin to facilitate radial artery cannulationCATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 3 2006FSCAI, Samir B. Pancholy MD Abstract Objectives: To study the effect of sublingual versus subcutaneous nitroglycerin on radial artery spasm caused by failed access attempts. Background: Radial artery spasm is the leading reason for failed radial access. We studied the efficacy of systemic versus local nitroglycerin in relieving radial artery spasm caused by needle entry resulting in failed cannulation. Methods: Fifty-two consecutive patients were studied. All patients had failed attempt at radial artery cannulation, resulting in loss of radial pulse. Patients were divided in three groups, group I (n = 11), observed without additional treatment, group II (n = 20), administered 400 mcg of sublingual nitroglycerin, and group III (n = 21), administered 400 mcg of subcutaneous nitroglycerin at the site of the lost radial pulse. All patients were monitored for the return of radial pulse. Demographics, hemodynamics, and time to return of radial pulse as well as ability to successfully cannulate the radial artery were recorded. Results: Seventy-two percent of group I patients, 90% of group II patients, and 100% of group III patients had re-establishment of radial pulse. The time to return of radial pulse was significantly shorter for group III compared with that for group II (3 ± 1 min vs. 8 ± 1 min respectively, P < 0.001). Re-establishment of radial pulse was faster in group II and group III compared with that in group I (18 ± 5 min, P < 0.001). Systolic blood pressure changes and headaches were less common in group III. Conclusion: Subcutaneous administration of nitroglycerin is superior in facilitating radial artery cannulation after initial failed attempt. © 2006 Wiley-Liss, Inc. [source] High remnant lipoprotein levels in patients with variant anginaCLINICAL CARDIOLOGY, Issue 6 2004Kunihisa Miwa M.D. Doctor-in-Chief Abstract Background: Dyslipidemia with increased oxidative stress but without elevation of low-density lipoprotein cholesterol has been recently implicated in the pathogenesis of coronary vasospasm. Hypothesis: Disordered triglyceride-rich lipoprotein metabolism may be linked to the genesis of coronary artery spasm. Methods: Both serum remnant lipoprotein (RLP) and ,-tocopherol levels were determined in 18 patients with the active stage of variant angina (VA), in 16 patients with the inactive stage of variant angina (IVA), and in 19 control subjects (CONTROL). Results: The RLP levels were significantly (p < 0.05) higher in VA (6.4 ± 2.7 mg/dl) than in IVA (4.4 ± 1.5 mg/dl). In contrast, ,-tocopherol levels were significantly lower in VA than that in CONTROL. Serum trigyceride levels were not significantly different among the study groups, although serum high-density lipoprotein cholesterol levels were significantly lower in VA than in CONTROL. Smoking was significantly (p < 0.05) more prevalent in VA (72%) than in IVA (25%) and CONTROL (37%). Serum RLP levels correlated positively with triglyceride levels (R = 0.73) and correlated inversely with ,-tocopherol levels (R = - 0.31) significantly in all study subjects. Conclusions: Patients with active stage of variant angina had higher RLP levels than inactive patients with variant angina and lower ,-tocopherol levels than control subjects. Disordered triglyceride-rich lipoprotein metabolism with increased oxidative stress appears to be linked to the activity of coronary vasospasm, suggesting a possible role in its pathogenesis.
