Control of postoperative pain by transcutaneous electrical nerve stimulation after thoracic operations.

BACKGROUND: Transcutaneous electrical nerve stimulation (TENS) has been used extensively to control postoperative pain, but its effects are controversial. This is probably due to the different types of operations performed and, therefore, to the varying intensity of postoperative pain. Here we present an extensive study with TENS in 324 patients who underwent different types of thoracic surgical procedures: posterolateral thoracotomy, muscle-sparing thoracotomy, costotomy, sternotomy, and video-assisted thoracoscopy. METHODS: Each patient cohort was randomly subdivided into three treatment groups: TENS, placebo TENS and control. The effectiveness of TENS was assessed by two factors: the time from the beginning of treatment to the request for further analgesia and the total medication intake during the first 12 hours after operation. RESULTS: Whereas posterolateral thoracotomy produced severe pain, muscle-sparing thoracotomy, costotomy, and sternotomy caused moderate pain, and video-assisted thoracoscopy caused only mild pain. The TENS treatment was not effective in the posterolateral thoracotomy group, but it was useful as an adjunct to other medications in the muscle-sparing thoracotomy, costotomy, and sternotomy groups. In contrast, representing the only pain control treatment with no adjunct drugs, it was very effective in patients having video-assisted thoracoscopy. CONCLUSIONS: These findings show that TENS is useful after thoracic surgical procedures only when postoperative pain is mild to moderate; it is uneffective for severe pain.

Recurrence of thymoma: analysis of clinicopathologic features, treatment, and outcome.

OBJECTIVE AND METHODS: This study reports clinicopathologic features, treatment, and outcome of 30 recurrent thymomas out of 266 totally resected thymomas. RESULTS: The mean disease-free interval to recurrence was 86 months. Recurrence occurred less frequently and after a longer disease-free interval after resection of encapsulated versus invasive thymomas. The presence of associated myasthenia gravis did not affect recurrence proportion, disease-free interval, or survival after recurrence. A local recurrence occurred in 11 patients, 17 patients had a distant recurrence, and the extent of the recurrence could not be determined in 2 cases. Surgical treatment of the recurrent tumor was attempted in 16 cases, and a total resection was possible in 10 cases; exclusive radiotherapy was done in 11 cases. Overall 5- and 10-year survivals were 48% and 24%, respectively. In a univariate analysis, survival was significantly better in the presence of a local recurrence and in case of a total resection of the recurrent tumor. The use of adjuvant therapy after the resection of the initial thymoma had no effect on reducing the incidence of recurrence, in prolonging the disease-free interval, or in improving survival after the development of the recurrence. In a multivariate survival analysis, significant prognostic factors were the presence of a local recurrence and total resection of the recurrent tumor. CONCLUSIONS: Surgical resection is recommended in patients with recurrent thymoma. Local recurrence and total resection of the recurrent tumor are associated with excellent prognosis. A poor prognosis may be anticipated in the presence of distant recurrence and when radical surgical treatment is not done.

A randomized study of chemotherapy with cisplatin plus etoposide versus chemoendocrine therapy with cisplatin, etoposide and the pineal hormone melatonin as a first-line treatment of advanced non-small cell lung cancer patients in a poor clinical state.

Recent studies suggest that the pineal hormone melatonin may reduce chemotherapy-induced immune and bone marrow damage. In addition, melatonin may exert potential oncostatic effects either by stimulating host anticancer immune defenses or by inhibiting tumor growth factor production. On this basis, we have performed a randomized study of chemotherapy alone vs. chemotherapy plus melatonin in advanced non-small cell lung cancer patients (NSCLC) with poor clinical status. The study included 70 consecutive advanced NSCLC patients who were randomized to receive chemotherapy alone with cisplatin (20 mg/m2/day i.v. for 3 days) and etoposide (100 mg/m2/day i.v. for 3 days) or chemotherapy plus melatonin (20 mg/day orally in the evening). Cycles were repeated at 21-day intervals. Clinical response and toxicity were evaluated according to World Health Organization criteria. A complete response (CR) was achieved in 1/34 patients concomitantly treated with melatonin and in none of the patients receiving chemotherapy alone. Partial response (PR) occurred in 10/34 and in 6/36 patients treated with or without melatonin, respectively. Thus, the tumor response rate was higher in patients receiving melatonin (11/34 vs. 6/35), without, however, statistically significant differences. The percent of 1-year survival was significantly higher in patients treated with melatonin plus chemotherapy than in those who received chemotherapy alone (15/34 vs. 7/36, P < 0.05). Finally, chemotherapy was well tolerated in patients receiving melatonin, and in particular the frequency of myelosuppression, neuropathy, and cachexia was significantly lower in the melatonin group. This study shows that the concomitant administration of melatonin may improve the efficacy of chemotherapy, mainly in terms of survival time, and reduce chemotherapeutic toxicity in advanced NSCLC, at least in patients in poor clinical condition.

Atypical mycobacteriosis in a lung transplant recipient.

Although mycobacterial infections are more frequent in lung transplant recipients than in other solid organ recipients only occasional reports of infection from atypical Mycobacteria have been reported in patients receiving lung transplantation. We present a case of pleural and cutaneous infection due to Mycobacterium fortuitum in a double-lung transplant recipient. The infection was rapidly responsive to therapy with a two drug regimen and no reduction of immunosuppression was necessary.

[Purpura fulminans in the newborn. Report of two cases successfully treated with heparin and antithrombin III].

Purpura fulminans is a rare form of disseminated intravascular coagulation characterized by rapidly progressive purpuric lesions, hypotension and, in some cases, fever. In neonates, purpura fulminans usually develops following deficiency of anticoagulant protein C or S, although acquired forms have been described. The management of disseminated intravascular coagulation is still controversial, with some studies finding a positive effect of anticoagulants and others showing no effect or even a detrimental one. Therefore, at present, management is limited to the treatment of underlying disease and replacement of clotting factors. Personal experience is reported on the efficacy of heparin in combination with antithrombin III in the treatment of purpura fulminans in two preterm neonates who did not have inherited deficiency of protein C or S and developed the disease possibly following prolonged labor (36 hours) in the first case, and maternal neoplasia, in the second. Both neonates presented with widespread cyanotic areas rapidly evolving in purpuric lesions and hemorrhagic bullae. Laboratory tests (prolonged prothrombin and partial thromboplastin time, fibrinogen and antithrombin III concentrations below normal ranges, d-dimer highly positive) were consistent with disseminated intravascular coagulation. In both cases anticoagulant treatment with heparin (50 UI/kg in bolus followed by 15 UI/kg/h) and antithrombin III was associated with resolution of disseminated intravascular coagulation and prompt amelioration of the purpuric lesions, without apparent side effects.

[General surgery after lung transplantation].

The authors report the case of correction of a large laparocele after lung transplant. Paradoxical respiration interfered with patient breathing. Three overlapping meshes were used to surgically correct the wound. Excellent results were achieved. Cortisone and immunosuppression therapy was not discontinued; infection risk was minimized by implementing rigorous asepsis and a wide spectrum antibiotic therapy.

Incidence of type I diabetes in the district of Catania, Sicily.

The incidence of type I (insulin-dependent) diabetes was determined in the district of Catania (eastern Sicily) in children under 15 years of age over a 3-year period (1 January 1989 to 31 December 1991). Two independent sources of information were used. The primary source was contact with all medical services in the province, and the secondary source was the personal identification cards issued to all diabetic patients by the National Health System necessary for obtaining free medical care. The information obtained was 99.6% complete. The overall incidence was 10.2/10(5) per year. This study provides the first standardized data on the incidence of type I diabetes in Sicily and is consistent with the possibility of regional deviations from the proposed north to south gradient.

Postoperative bronchopleural fistula: endoscopic closure in 12 patients.

Twelve consecutive patients with postresectional bronchopleural fistula were treated with endoscopic application of tissue glue adhesive (methyl-2-cyanoacrylate). Eight patients had associated empyema. Endoscopic gluing was successfully accomplished in 10 cases (success rate of 83%). The two failures both had fistulas of 0.5 cm or larger. Bronchopleural fistulas developed in 8 patients early after the intervention (< 15 days): of the 4 patients without associated empyema, 3 had their fistula definitely closed after endoscopic treatment. Similarly, 3 of the 4 patients with early bronchopleural fistulas and empyema were cured after endoscopic closure of the fistula and appropriate management of the empyema. Four bronchopleural fistulas occurred late after the operation (> 15 days) and all had associated empyema. Successful endoscopic closure of the fistula was accomplished in all. Resolution of the empyema occurred in 1. We conclude that endoscopic application of tissue adhesive may be a valid therapeutic measure in selected patients with postresectional bronchopleural fistula. In late bronchopleural fistula with empyema, the closure of the fistula can be achieved, but empyema may persist and require additional surgical procedures.

Combined radiosurgical treatment of Pancoast tumor.

Operative technique and long-term results of 60 consecutive patients with Pancoast tumor treated with combined radiosurgical treatment were evaluated. External radiation therapy was administered preoperatively in a dose of 30 Gy in 50 patients. Operation was considered radical (R0) in 36 patients (60%). A microscopic invasion of the margin of resection (R1) was observed in 5 patients (8.3%). In 19 patients (31.6%) the operation was considered presumably not radical (R2). Three patients died in the postoperative period (5%). Fourteen major postoperative complications occurred in 13 patients (21%). Seven patients had recurrence of pain postoperatively. Overall 3- and 5-year actuarial survival rates were 34% and 17.4%, respectively. The corresponding figures for the R0 and combined R1-R2 groups were 45.8% and 23.5% (R0), and 11.4% (R1-R2; no 5-year survivors were observed in this group) (p < 0.025). Median survivals in the R0 and combined R1-R2 patients were 19 and 7 months, respectively. Different median survivals for the patients with residual tumor were as follows: intervertebral foramina, 5 months; subclavian artery (isolated), 9 months; subclavian artery (in association), 7 months; brachial plexus, 4 months; and vertebral body, 7 months. We conclude that combined radiosurgical treatment represents a valuable therapeutic option in the treatment of Pancoast tumor. In case of residual tumor a poor outcome may usually be anticipated, but in the majority of these patients the operation permits good control of the pain.

Successful management of hemorrhage from the pulmonary artery stump after lobectomy for bronchogenic carcinoma.

Pulmonary bleeding from the arterial stump following lung resection is a life-threatening complication requiring immediate surgical correction. Predisposing conditions are almost always represented by bronchopleural fistula and empyema. The operation often represents a major challenge to the thoracic surgeon, because of the choice of the most appropriate surgical access, the optimal technique to control the bleeding, as well as to treat the associated bronchopleural fistula. We present a case of successful treatment of hemorrhage from the pulmonary artery stump associated with BPF and empyema following lobectomy for bronchogenic carcinoma. A standard postero-lateral thoracotomy using the previous incision was used with adequate exposure of the source of bleeding and the bronchopleural fistula.

[Iatrogenic esophago-tracheal fistula treated with endoscopically administered fibrin glue].

Successful closure of a iatrogenic tracheoesophageal fistula by means of bronchoscopic application of fibrin glue in a 77-year old patient is reported. The fistula was completely obliterated after a single application of the glue, with resolution of the clinical and radiological signs. The procedure may be suggested as an alternative to surgery or as first attempt before surgery in very selected patients with TEF.

[Post-traumatic hernia of the diaphragm].

The paper reports the series of post-traumatic hernias of the diaphragm observed during the period between 1954 and June 1992. This group of 77 patients (59 males and 18 females) were aged between 6 and 75 years old. Both acute and chronic hernias were reported; in 60 cases the diaphragmatic lesion was on the left, in 9 cases on the right, and there were 8 cases of laceration to both hemidiaphragms. The most frequently herniated organ was the stomach, followed by the transverse colon and spleen. With regard to the access route used, the authors draw attention to the fact that during the first twenty years of the series thoracotomies were prevalently used, whereas during the last decade laparotomy has been used in cases of early post-traumatic hernia, thoracotomy in cases of chronic post-traumatic hernia or if there is suspected damage to organs and intrathoracic structures.

Growth and growth hormone in children during and after therapy for acute lymphoblastic leukaemia.

Growth impairment and growth hormone (GH) deficiency have been reported in children treated for acute lymphoblastic leukaemia (ALL). We have studied growth and GH secretion in a group of 50 patients, affected by ALL, during a 2- to 5-year period after diagnosis, and in 12 "long-term-survivors". We observed a significant decrease in growth velocity during the 1st year (in particular during the first 6 months) of therapy and a catch-up growth after the end of therapy. "Long-term survivors" did not exhibit a significant reduction of height standard deviation score (SDS), as compared to height SDS at diagnosis. None of the patients showed GH deficiency. Our data indicate that chemotherapy significantly affects growth of patients treated for ALL, whereas radiotherapy-at the doses used in this study-does not induce GH deficiency, at least not within 9 years after diagnosis.

Growth and development in white patients with sickle cell diseases.

We have evaluated height, weight, bone age, somatomedin-C levels, and pubertal development in 114 Sicilian patients affected by sickle cell diseases (SCDs). Thirty-one had homozygous sickle hemoglobin (SS), 55 S-beta 0 thalassemia, and 28 S-beta + thalassemia. In both children and adults, the mean height and weight were approximately 1 SD below the normal mean for age. The height was below the normal range only in a few subjects (8 children and 4 adult women). Somatomedin-C levels were within the normal range in most of the patients (37/44 children and 17/22 adults). Bone age revealed a slight delay in skeletal maturation (mean chronological age and bone age were 7.7 +/- 3 and 7.11 +/- 2.9 respectively; p < 0.05). Mean age at menarche was increased compared to normal subjects. Our findings show that Sicilian patients with SCD exhibit a moderate delay of growth and adolescence but attain a final height within the normal range.

Comparative approach to the evaluation of hemoglobin A2 by two different methods: high-performance liquid chromatography and DE-52 microchromatography.

Hb A2 was determined in 477 subjects: 77 were affected by iron deficiency anemia, 172 were carriers of beta-thalassemia trait and 228 were normal controls. Hb A2 was determined by both DE-52 microchromatography and high-performance liquid chromatography (HPLC). The analysis of the data by linear regression demonstrated that the methods furnish overlapping results. Our findings show that HPLC is a rapid and easily reproduced method which allows a quantitative and qualitative discrimination of the various Hb fractions, making it a valid tool in screening programs for hemoglobinopathies.
