RESUMO
AIM: The aim of this study was to compare the effects of iloprost and lumbar sympathectomy (LS) in the treatment of Buerger's disease. METHODS: Two hundred patients with rest pain and/or ischemic ulcers were randomized to undergo LS or 28-day intravenous treatment of iloprost. The primary endpoint was complete healing without pain or major amputation at 4 and 24 weeks. The secondary endpoints were analgesic requirement, reduction in the ulcer size, 50% reduction of the ulcer, and shift in the modified SVS/ISCVS clinical status grading scale. RESULTS: The comparison was carried out in 162 patients (iloprost: n=84; LS: n=78). Complete healing rate was 61.9% in the iloprost group, but 41% in the LS group at the 4th week (P=0.012); respective values for the 24th week were 85.3%, 52.3%, P<0.001. Analgesic requirement was lower in the iloprost group at the 4th and 24th weeks (P=0.01, and P=0.098, respectively). The size of the ulcers decreased more in the iloprost group than the LS group (P=0.044 and P=0.035 at 4th and 24th weeks); 50% reduction in the ulcer size in the iloprost group was greater than in the LS group (P=0.001 and P=0.009 at 4th and 24th weeks). SVS/ISCVS grading scale demonstrated a better clinical benefit in patients treated with iloprost (P<0.001 at 4th week, and P<0.001 and at 24th week). CONCLUSIONS: The results of this independent study indicate that using iloprost relieves ischemic symptoms better than LS. In the era of stable prostacyclin analogues, there is no reliable evidence to support the use of LS in Buerger's disease.

INTRODUCTION: In this report, we share our omentoplasty experience in a patient with recurrent left ventricular assist device (LVAD) drive line infection. Drive line infection is a life-threating complication for the patient and a difficult problem for surgeons to resolve. CASE REPORT: In our patient, after LAVD implantation recurrent drive line infection episodes occurred and standard therapeutic strategies failed to cure the infection. Therefore, we performed an old, well-known omentoplasty plasty technique to heal the abscess. CONCLUSIONS: After omentoplasty and appropriate antibiotic therapy, the drive line infection healed uneventfully. The patient is still under control for 14 months without any signs of infection. Omentoplasty may be kept in mind for patients with resistant drive line infections.

In addition to preventing tissue energy loss during cardiopulmonary bypass, pentoxifylline (Ptx) prevents the production of pro-inflammatory cytokines as well. The aim of this study was to investigate whether Ptx decreases the inflammatory effects of cardiopulmonary bypass on the lungs during open-heart surgery. The patients in the study group (n = 15) who were going through an open-heart surgery had 500 mg l(-1) of Ptx added to their prime solution, whereas the patients in the control group (n = 10) only received prime solution. Pre-pump and post-pump blood samples were obtained from both groups and assayed for interleukin-6 (IL-6), interleukin-8 (IL-8) and tumour necrosis factor alpha (TNFalpha). Lung tissue samples that were obtained after the pump were examined with light microscopy and stained for tissueTNFalpha. Non-parametric Wilcoxon test was utilized for statistical evaluation. In the post-pump period, the difference in the IL-6, IL-8 and TNFalpha levels of the two groups was found to be statistically significant (P<0.005). The tissue samples from the control group had significant staining with TNFalpha. We think that Ptx has important protective effects on the lungs during cardiopulmonary bypass.

BACKGROUND: Tricuspid annuloplasty procedures have been widely performed in clinics for many years. The Kalangos Biodegradable Tricuspid Ring (Kalangos Biodegradable Tricuspid Ring, Bioring SA, Lonay, Switzerland) is a novel prosthesis for the treatment of tricuspid insufficiency. The aim of this study was to evaluate the clinical and echocardiographic results of this novel prosthesis for functional tricuspid insufficiency. METHODS: Between October 2005 and May 2006, 15 patients with the diagnosis of moderate or severe functional tricuspid insufficiency were treated by implantation of a Kalangos Biodegradable Tricuspid Ring. All patients were evaluated clinically and by echocardiography preoperatively, and control tests were performed at the end of the 1st and 6th month following surgery. RESULTS: Moderate and severe insufficiency was documented in 11 and 4 patients, respectively, in the preoperative tests. 1 and 6 months after surgery, 4 patients had trace and 1 patient had mild tricuspid insufficiency, while 10 patients had none. At the 1st and 6th month follow-up, systolic pulmonary arterial pressure, right atrial dimension and right ventricular diastolic diameter were found to be significantly lower than the preoperative values ( P < 0.0001). The right atrial diameter and tricuspid valve area had decreased significantly at the end of the 1st month; however, no significant difference was found between the 1st and 6th month tests ( P > 0.05). Three-quarters of the annuloplasty ring had degraded at 6 months. No complications related to the prosthesis or the procedure occurred within this period. CONCLUSIONS: Kalangos Biodegradable Ring is a promising prosthesis in patients with functional tricuspid insufficiency, with encouraging initial results.

Inflammatory pseudotumors of the lung are uncommon in the thoracic surgical literature. These masses resemble carcinoma of the lung radiographically and are discovered only at time the of histologic review of the resected specimen. We report a case of inflammatory pseudotumor that was excised without pulmonary resection, although it completely filled the right hemithorax. We think it was the greatest inflammatory pseudotumor in the English literature.

We compared the effectiveness of intrapleural urokinase versus normal saline via a thoracostomy tube in the treatment of parapneumonic empyema in a randomised controlled study. Forty-nine patients with parapneumonic empyema were randomly assigned to receive either intrapleural urokinase or normal saline treatment. The daily volume instilled through a chest tube was 100 ml in both groups. Urokinase (100,000 IU/day) was diluted in normal saline before instillation. The mean duration for defervescence was shorter (7 +/- 3 vs 13 +/- 5 days, p<0.01) and the mean volume of drained fluid during the five-day treatment period was significantly greater in the urokinase group (1.8 +/- 1.5 vs 0.8 +/- 0.8 litres, p<0.001) than in the control group. The subsequent decortication rate was 60% and 29.1%, respectively (p<0.001). The duration of hospitalisation was also shorter in the urokinase group (14 +/- 4 vs 21 +/- 4 days, p<0.001) than in the saline group. We conclude that intrapleural instillation of urokinase in the management of parapneumonic empyema provides a better outcome and reduces the need for decortication.
