Disc coablation and epidural injection of steroids: a comparison of strategies in the treatment of mechanical spinal discogenic pain.

In this study two strategies in the treatment of Mechanical Spinal Discogenic Pain have been compared: Disc Coablation and Epidural Injection of Steroids. In 2003 50 patients treated with one or two epidural injections have been selected "ad random" and 50 patients treated with disc coablation. Comparison of the data indicated an improvement of average VAS when relaxed for both groups (p < 0.01), while after slight-moderate strain, this value was significant only after coablation (p < 0.001). Finally, average VAS was clearly lower (p < 0.01) after coablation as compared to epidural injections.

Ischaemic mitral valve regurgitation: a surgical approach.

UNLABELLED: The aim of this study IS to determine surgical results after surgical mitral valve repair in ischaemic mitral regurgitation. MATERIALS AND METHODS: Between January 1999 and June 2000, 64 patients (5.1% of overall patients) underwent myocardial revascularization and mitral valve surgery. A Cosgrove-Edwards mitral annuloplasty ring was used in 59 cases (92.2%). Average patient age was 64.3 +/- 12.4 years (38 males, 21 females). Average degree of mitral regurgitation was 2.8 +/- 0.6. Average NYHA class was 3.5 +/- 0.5. Average ejection fraction (EF) was 40 +/- 12.5 percent. RESULTS: Post-operative 30-day mortality was 3.4% (2 patients). The follow-up was complete for 95 percent (mean 20.4 +/- 4.8 months for patients) and data showed an improvement of NYHA class (mean value 1.8 +/- 0.2) (p = 0.01) and ejection fraction (mean value 51.7 +/- 10.2) (p = 0.05) with residual mitral regurgitation value of 0.6 +/- 0.7. CONCLUSIONS: Mitral valve repair in coronary artery disease improves left ventricular function, quality of life and survival rate with low operative risk. Perioperative transesophageal echocardiography has a central role in surgical decision making.

[Total arterial myocardial revascularization: surgical technique and mid-term results].

The purpose of this study is to evaluate perioperative and mid-term results of total arterial coronary revascularization in our experience and to establish its safety. One-hundred and ninety-one patients underwent total arterial coronary revascularization at our Institution from February 1997 to August 2000. The mean age was 60.1 years. Of the patients, 45% had three coronary vessels disease, 12% a left main coronary artery disease and 2.6% of them were classified urgent. Mean ejection fraction was 59.6%. Three hundred and thirty-four comprehensive anastomoses were performed; mean grafts per patient was 1.8. A Y or T graft with the left internal thoracic artery was used in 21 patients. The in-hospital mortality rate was 1% (2 patients). Complications included low cardiac output syndrome in 2.8% of patients, acute myocardial infarction in 0.9% and acute renal insufficiency in 3.1%. Intraaortic balloon pump was used in 1.8% of patients. At a mean follow-up of 899 days the first 81 patients contacted are all free of angina but two (one experienced an acute myocardial infarction and another one died for a pulmonary neoplasia). We conclude that total arterial coronary revascularization is a safe surgical technique, providing excellent perioperative and mid-term results.

[Combined cardiac surgery and aneurysm of subrenal abdominal aorta].

The authors explain their experience about the combined correction of cardiac pathology and infrarental aortic aneurysm repair. Seven patients of mean age of 63 years underwent simultaneous myocardial revascularization (5 cases) or aortic valve replacement (2 cases) and abdominal aortic aneurysm repair with bifurcated vascular prosthesis (6 cases) and tubular prosthesis (1 case) between 1987 and 1995. Cardiac operation was performed first with a mean number of 2.4 coronary artery by-pass grafts, with a mean by-pass time of 51 min, and a mean abdominal aortic cross-clamp time of 46 min. The mean total operating time was 231 min. All patients were managed postoperatively in the cardiac intensive care unit with a mean duration of 2.5 days and were transfused with a mean of 5 units of donor blood. The mean postoperative hospitalization was 9 days. One patient died for complication of postoperative myocardial infarction. The authors conclude that combined cardiac operation and abdominal aortic aneurysm repair is feasible in carefully selected patients.

[Low-flow anesthesia: isoflurane increment kinetics as a function of the rotatory circuit volume].

OBJECTIVE: Study of the increment of isoflurane volume concentration in two rotatory circuits having different capacity during low flow narcosis. DESIGN: Descriptive comparison of different halogenate concentration in circuits connected to two patient groups and evaluation of the significance of the observed differences. SETTING: Surgery theatres of a district Public Hospital. PATIENTS: 16 female patients included in the same age, weight and body surface group, showing neither obstructive nor restrictive lung diseases. According to the surgical treatment used (abdominal or major gynecological surgery) the patients were then divided into two groups of 8 each. MEASUREMENTS AND MAIN RESULTS: After opening the halogenate nebulizer, dry measurement of the isoflurane concentration detected for 30 minutes in the inspiratory and expiratory circuit segment by means of monitors at pre-determined intervals, before abdominal or major gynecological surgery. Simultaneous measurement of isoflurane uptake by means of indirect methods (heart frequency, average arterial pressure, use of muscle relaxing agents). The analysis of the measured values showed higher isoflurane concentrations and a faster percent increase in the small circuit than in the big one (resp. 0.9% vs 0.71% in the inspiratory segment and 0.59% vs 0.4% in the expiratory one, with p < 0.005 and I.C. = 99.00%). CONCLUSIONS: This study demonstrates how the different kinetics of the isoflurane increment in the rotatory circuit is mainly related to the circuit volume. To eliminate the problems due to the "low compliance" of the small circuit (collection of toxic gases) and to the "high compliance" of the big circuit rotatory (awareness), circuits with varying volume might be introduced.

Prevention of deep venous thrombosis by a new low molecular weight heparin (Fluxum) in cardiac surgery.

The prophylactic deep venous antithrombotic efficacy of a low molecular weight heparin (LMWH) was compared with traditional unfractionated calcium heparin in 39 patients submitted to cardiac surgery. The patients were allocated at random to receive either LMWH-Fluxum 3200 IUaXa daily (Group A: 20 patients) or calcium heparin 5000 IU three times daily (Group B: 19 patients). Both treatments were started on the first day after surgery and continued over the fourth postoperative days. One or more risk factors for deep venous thrombosis in addition to the cardiac pathology were present in all the patients of group A and in 13 (72.2%) of group B. Mean times of surgery, blood loss during the perioperative period and number of blood units transfused in both groups were not statistically significant. The deep venous system was investigated by continuous wave Doppler and real time colour Echotomography. No evidence of thrombosis was detected in the two groups. Side effects and subcutaneous hematomas were present in only four patients of group B. Both drugs showed good tolerance, provoking no variations of the main laboratory parameters. We conclude that Fluxum (LMWH) for the efficacy and convenience given by a single daily dose, could represent an alternative choice in the prevention of deep venous thrombosis in cardiac surgery.

[Morphine sulfate per os combined with octreotide in continuous peridural therapy in oncologic pain. Description of a clinical case].

The authors emphasize the analgesic synergy of the association of morphina sulphate per os and octreotide in continuous epidural therapy in a patient affected by a late prostatic cancer with diffuse skeletal metastases. They, moreover, support cenesthesia regulating and, perhaps, antiproliferative activity of octreotide. A few patients treated with octreotide in continuous epidural therapy showed neurological diseases of behaviour.

[Assessment of perioperative myocardial damage based on circulating heavy chain myosin fragments].

To evaluate myocardial damage induced by coronary bypass surgery, to construct a reference data set in postoperative patients and to ascertain the impact of perioperative myocardial infarction on myosin release from sarcolemmal membrane we serially measured levels of serum fragments of myosin heavy chains by means of monoclonal antibody immunoradiometric assay (MYOSIN IRMA ERIA Pasteur). After surgery serum levels of myosin increased from third postoperative day and peaked on seventh day. Peak myosin levels did correlate with enzymatic activities of CPK (r = 0.69; p < 0.001) and of CPK-MB (r = 0.75; p < 0.001). Six patients suffered postoperative myocardial infarction: in these patients myosin levels were significantly different from those without infarctions (3651 +/- 1569 versus 699 +/- 206 ng/ml; p < 0.01). No correlation could be demonstrated between cardiopulmonary bypass time or aortic cross clamp duration. The rise of myosin levels observed in nearly all patients suggests a minor intraoperative damage to the contractile apparatus that sometimes is diagnosed as myocardial infarction and often does not meet clinical diagnostic criteria.

Cutaneous hyperpigmentation induced by amiodarone hydrochloride.

Amiodarone (Cordarone) is an iodinated compound widely used in the treatment of cardiac arrhythmias for more than a decade. A patient who developed a persistent blue-gray skin pigmentation of the light-exposed areas following long-term amiodarone hydrochloride administration is reported. The cutaneous signs and the ultrastructural findings are described. This rare iatrogenic hyperpigmentation is peculiarly due to lipofuscin and not melanin deposits. Its pathogenesis may be related to the basic action of the drug on the lysosome and to the extra phototoxic-induced lysosomal damage, which accounts for the specific location of the hyperpigmentation over the light-exposed areas.

Right atrial hemangioma.

A case of right atrial hemangioma as a rare tumor of the heart is reported. Because of its single, pedunculated mass, surgical excision of the tumor resulted in the complete treatment. Histologically, it was classified as arteriolar type. The importance of recent non-invasive techniques to diagnose these tumors during life is emphasized.
