Methods of surgical therapy in pulmonary hydatid disease: is capitonnage advantageous?

BACKGROUND: Hydatid disease of the lungs is still a serious health problem for some Mediterranean countries. The best surgical therapy for the treatment of this disease is still unclear. In this clinical retrospective study, we aimed to investigate whether capitonnage is an effective therapy method for a pulmonary hydatid cyst or not. METHODS: Between 1990 and 2004, 89 patients (49 male and 40 female) each with a pulmonary hydatid cyst were treated surgically. The patients were divided into two groups based on whether capitonnage was carried out (group 1, n = 44) or not (group 2, n = 45). Cystotomy and the closure of the bronchial openings were carried out in both groups. The results were assessed in two groups during a 1 year follow-up period. The groups were comparable with regards to their clinical, operative and demographic characteristics. RESULTS: There was no mortality, and no significant difference in hospitalisation time between the two groups. It was 8.2 +/- 3.2 days for group 1 and 8 +/- 3.1 days for group 2 (P = 0.89). The most serious complications were restricted bronchopleural fistula (only one patient in group 2), empyema (only one patient in group 1 and two patients in group 2), and prolonged air leak (five patients in group 1 and six patients in group 2). These results were not valuable statistically (P = 1.00, P = 1.00 and P = 0.78, respectively). CONCLUSIONS: We conclude that it is not an advantage to carry out capitonnage when treating pulmonary hydatid cysts.     

Surgical management of tuberculosis-related hemoptysis

Background

Tuberculosis is a disease that is often treated with chemotherapy. However, medical treatment usually fails in the management of tuberculosis-related hemoptysis. In this paper, we review our experience in the surgical treatment of tuberculosis-related hemoptysis.

Methods

Fifty-nine patients with tuberculosis-related hemoptysis (46 men, 13 women) who underwent surgical treatment were enrolled in this study. A thoracotomy was performed urgently in 21 patients with massive (>600 mL daily) hemoptysis, and within the first 2 days in 24 with major (200 to 600 mL daily) hemoptysis, and within the first 4 days in 14 with persistent minor (<200 mL daily) hemoptysis.

Results

A chest roentgenogram showed cavitary lesion in all of the patients with massive hemoptysis (21 patients), in 22 of 24 patients with major hemoptysis, and in 3 of 14 patients with persistent minor hemoptysis. Pneumonectomy was performed in 4 patients, lobectomy in 39 patients, and segmentectomy or wedge resection in 16 patients. The average hospitalization period was 13 days. The mortality rate was 6.8% perioperatively. Of the patients deceased, 3 were intubated with a single-lumen endotracheal tube and 1 with a double-lumen endotracheal tube. During the postoperative period, empyema and bronchopleural fistula developed in 3 patients, and no other severe complications occurred. The average postoperative follow-up period was 3 years. The number of thoracotomies for tuberculosis performed in the years from 1995 to 2003 was significantly decreased, compared with the years between 1985 to 1994 (p = 0.042).

Conclusions

In tuberculosis-related hemoptysis, thoracotomy with double-lumen endotracheal intubation and resection of the cavity may be curative and lifesaving.     

Prospective, Randomized, Placebo-controlled Study of the Effect of TENS on Postthoracotomy Pain and Pulmonary Function

We investigated the efficacy of transcutaneous electrical nerve stimulation (TENS) for postthoracotomy pain control in a prospective, randomized, double-blind, placebo-controlled study. We studied two groups of patients undergoing posterolateral thoracotomy. In group 1, TENS was used postoperatively on 60 patients for 5 days. Group 2 contained 56 patients without TENS. In both groups a visual analog scale (VAS) was used to indicate if analgesia was needed. When the VAS was higher than 4, an analgesic was administered. We observed the forced expiratory volume in 1 second (FEV₁), the forced vital capacity (FVC), partial arterial oxygen pressure (PaO₂), partial arterial carbon dioxide pressure (PaCO₂), and how many doses of analgesia were given at postoperative 0 (extubation time), 2, 6, 12, 24, 48, 72, and 120 hours. TENS was not employed in patients with cardiac or neurologic disease. In group 1, TENS reduced the need to administer opioids during the 5-day postoperative period. This result is statistically significant (P = 0.013). Additionally, following the sixth postoperative hour, TENS increased the spirometric breath function. The FEV₁, FVC, and PaO₂ were high and PaCO₂ was low when the first group is compared to the second. All these results are statistically significant (P = 0.012, P = 0.01, P = 0.024, and P = 0.02 respectively). We observed that TENS produced no evidence of side effects or intolerance in the patients of group 1. TENS is thus beneficial for pain relief following thoracotomy and has no side effects. Consequently, the routine use of TENS following thoracic surgery is recommended.     

Antioxidant properties of propofol and erythropoietin after closed head injury in rats

Reactive oxygen species play a role during brain injury due to closed head trauma. Enzymatic or nonenzymatic antioxidants may protect brain tissue against oxidative damage. The present study was performed to assess the changes of endogenous indices of oxidative stress in serum from rats subjected to head trauma and whether treatment with propofol and/or erythropoietin (EPO) modifies the levels of endogenous indices of oxidative stress. For these purposes, female Wistar Albino rats were divided into five groups: non-traumatic sham group, trauma performed control, trauma with propofol (i.p.), trauma with EPO (i.p.) and trauma with propofol and EPO performed study groups. At the end of the experimental procedure, blood was taken by cardiac puncture to determine superoxide dismutase (SOD) and xanthine oxidase (XO) activities as well as malondialdehyde (MDA) and nitric oxide (NO) levels in serum. Serum MDA level of control traumatic brain injury (TBI) group was significantly higher than sham operation group (p<0.012). Serum MDA levels in propofol, EPO and propofol+EPO groups were found to be decreased in comparison with control group (p<0.039, p<0.030 and p<0.018, respectively). Serum NO level was found to be increased in TBI group, but difference was not statistically significant when compared to sham-operated group (p=0.092). Propofol, EPO and propofol+EPO administration efficiently reduced serum NO levels to reach sham-operated group (p<0.002, p<0.001 and p<0.015, respectively). These results suggested that acute administration of both propofol and EPO altered the indices of oxidative stress similarly against brain injury due to trauma.     

Bilateral carpal tunnel syndrome associated to familial Mediterranean fever

A unique case of bilateral severe carpal tunnel syndrome due to familial Mediterranean fever is reported. The syndrome was diagnosed by clinical examination and electrophysiological studies. Bilateral transverse carpal ligaments were released and the biopsy specimens revealed systemic type A amyloidosis. Up to our knowledge, the co-existence of bilateral carpal tunnel syndrome and familial Mediterranean fever has not been reported previously in the literature.     

The prevalence of stress urinary incontinence among women operated on for abdominal wall hernias

The high co-occurrence of an abdominal wall hernia (AWH) and stress urinary incontinence (SUI) suggests that there is a common factor in the etiopathogenesis of these disorders in these patients.
