[So-called benign broncho-esophageal fistula].

Broncho-oesophageal fistulae are rare lesions and may be benign or malignant. The articles in medical literature generally concern one case of BEF, and rarely more cases. The term "benign" is debatable, considering the severity of this disease in view of the aetiology and the bronchopulmonary complications. The aetiology in the past was connected to tuberculosis or toxoplasmosis, now to bacterial, viral or fungal infections. The Authors report three acquired cases and one congenital. They confirm the importance of anamnesis, symptomatology and oesophagography for diagnosis and CT scan for detection of pulmonary lesions. The treatment is surgical with resection of fistula and suture of the oesophagus and bronchus, interposing pleura or pericardium or intercostal muscle.

Luxatio cordis due to right pericardium tear, a difficult diagnosis: report of a case.

BACKGROUND: Dislocation of the heart is a rare complication of thoracic blunt trauma. A high index of suspicion of pericardium rupture is necessary to formulate an early diagnosis to reduce morbidity and mortality. PATIENTS: A 23-year-old man suffered a blunt thoracoabdominal trauma and was admitted 3 days later to a university hospital ICU for right heart luxation due to right pericardial tear. Mechanical ventilation delayed radiological findings. METHODS AND RESULTS: Surgery by repositioning the heart and repairing the pericardial tear allowed restoration of hemodynamic equilibrium.

Phase I-II study of gemcitabine and paclitaxel in pretreated patients with stage IIIB-IV non-small cell lung cancer.

Gemcitabine and paclitaxel are among the most active new agents in non-small cell lung cancer (NSCLC) and are worth considering for second-line chemotherapy. In this phase I-II study, we combined gemcitabine and paclitaxel for second-line treatment of advanced NSCLC. Gemcitabine doses were kept fixed at 1000 mg/m2 on day 1 and 8, and paclitaxel doses were escalated from 90 mg/m2 on day 1 of the 21-day cycle. Thirty-seven patients were treated at six different dose levels. Grade 4 neutropenia was dose-limiting toxicity (DLT), since it occurred in two out of six patients treated at paclitaxel 240 mg/m2; the paclitaxel dose level just below (210 mg/m2) was selected for phase Il evaluation. Non-hematologic toxicity was mild. One complete response (CR) (3%) and 13 partial responses (PR) (36%) were observed in 36 evaluable patients for an overall response rate of 39% (95% C.I., 23-57%). Median duration of response was 35 weeks (range, 8-102). All of the observed objective responses occurred in the 19 patients who had previously responded to the first-line therapy. Median survival was 40 weeks (range, 8-108 weeks). The combination of gemcitabine and paclitaxel is a feasible, well-tolerated, and active scheme for second-line treatment of advanced NSCLC; further evaluation, at least in selected patients, such as those previously responding to first-line chemotherapy, is definitely warranted.

High-dose rate brachytherapy of bronchial cancer: treatment optimization using three schemes of therapy.

PURPOSE: Our aim is to demonstrate that a fractionated high-dose rate endobronchial brachytherapy (HDRBT) treatment is tolerable for patients with advanced (IIIA-IIIB) non-small cell lung cancer and gives an improvement of symptoms. Patients and Methods. From January 1992 to July 1997, we treated 320 patients with external beam radiotherapy (EBRT) and concomitant HDRBT with Ir192. Eighty-four patients received 10 Gy in one fraction from January 1992 to March 1993 (Group A); 47 patients received two fractions of 7 Gy each from April 1993 to December 1993 (Group B), and 189 patients received three fractions of 5 Gy each from January 1994 to July 1997 (Group C). RESULTS: Mean survival from diagnosis is 11.1 months and mean survival from last HDRBT is 9.7 months. The symptomatic response rate is 90% for dyspnea, 82% for cough, 94% for hemoptysis and 90% for obstructive pneumonia. Performance status was improved in 70% of patients. Follow-up is in the range of 5-36 months with 280/320 evaluable patients (87.5%) (40 patients were lost to follow-up). For the patients treated with three fractions of HDRBT plus EBRT, a smaller number of side effects occurred while relief from symptoms linked to bronchial obstruction and survival was similar for the three groups. CONCLUSIONS: A three-fraction brachytherapy results in fewer side effects, such as bronchial fibrosis with or without stenosis, while survival and symptomatic relief are similar in the three groups treated.

[Palliative surgical treatment of thoracic esophageal cancer].

BACKGROUND: Esophageal carcinoma is frequently diagnosed at an advanced stage, therefore most patients may only benefit from surgical or endoscopic palliation. METHODS: From 1982 to 1998, out of 247 patients who underwent palliation for thoracic esophageal carcinoma, 29 (11.7%) underwent surgical palliation. Eight received a palliative resection, 10 a bypass, 5 a jejunostomy and 6 a gastrostomy. A retrosternal transposition of the stomach (17 patients) and colon (1 patient) was performed. In 15 out of 29 patients palliation was decided during surgical exploration. All resected patients underwent postoperative radiotherapy (400 Gy) while 3 received also preoperative chemotherapy (PDD and % FU). RESULTS: Seven temporary neck fistulas and 9 cardiorespiratory complications were recorded. Two patients (11%) died of severe cardiac and respiratory insufficiency. Mean survival for resected patients was 12.5 months (range 3-21), higher than for bypass (11.5 months; range 3-18) and for jejunostomy or gastrostomy (5 months; range 2-12). CONCLUSIONS: Palliative resection, when technically feasible, is the treatment of choice in advanced thoracic esophageal carcinoma in selected patients. The type of procedure to be performed depends on site, extent of the disease and surgeon's experience together with the quality of life expected by the patient.

Middle mediastinum lesions: preliminary experience with CT-guided fine-needle aspiration biopsy with a suprasternal approach.

The technical feasibility and safety of a suprasternal approach in the computed tomography (CT)-guided biopsy of lesions in the middle mediastinum was studied in 30 patients. Patients were positioned on their back with their head hyperextended. Biopsies were performed with local anesthesia and 22-gauge needles. Adequate biopsy material for diagnosis was obtained in 25 (83%) of 30 patients. A single biopsy specimen was sufficient in 14 patients, but as many as three biopsy specimens were necessary in 16 patients. Nineteen (63%) patients had various histotypes of lung cancer. In 24 (89%) of 27 adequate specimens, findings at fine-needle aspiration biopsy were consistent with findings at pathologic examination. No major complications were observed. CT-guided biopsy of middle mediastinum lesions was safe and successful with a suprasternal approach.

Analysis of polyunsaturated fatty acids in newborn sera: a screening tool for atopic disease?

It has been demonstrated that patients with atopic disease have anomalies of fatty acid composition, as a result of altered metabolism or abnormal incorporation of fatty acids into the tissues. In the present study, in 57 newborns 'at risk' for atopic disease, the polyunsaturated fatty acid (PUFA) levels were found to be lower in cord blood in infants who subsequently developed atopic disease than in non-atopics. In all babies, levels of arachidonic acid and dihomo-gamma-linolenic acid in sera at 1 and 3 months of age were lower than those in cord blood. These changes were more marked in children who subsequently developed atopic disease, and in those who, independently of signs and/or symptoms of atopic disease, were formula-fed. A comparison between IgE and PUFA levels revealed no significant differences at any tested time interval. In conclusion, our data suggest that in children 'at risk' for atopy, PUFA levels may be predictive of atopic disease.

Methylprednisolone bolus: a novel therapy for severe atopic dermatitis.

Seven children suffering from severe atopic dermatitis, unresponsive to standard therapy, received an iv bolus dose of methylprednisolone (20 mg/kg/day) for three days. Immunological parameters were evaluated before and after treatment. At the end of bolus therapy both skin lesions and itching improved for several months in five of seven patients. No side effects were observed, but a significant and transient lymphopenic response occurred, with lower CD4+ than CD8+ lymphocyte counts. Our data suggest that this therapy may be a novel and safe therapeutic approach in severe atopic dermatitis.

Tumor markers and lung cancer: correlation between serum and bronchial secretion levels of CEA, TPA, CanAg CA-50, NSE and ferritin.

The levels of carcinoembryonic antigeny (CEA), tissue polypeptide antigeny (TPA), CanAg 50, neuron specific enolase (NSE) and ferritin were determined in bronchial secretion and serum of patients with neoplastic and non-neoplastic lung diseases. Simultaneous determination of two or three markers in the serum and in bronchoalveolar lavage (BAL) may be clinically useful for the diagnosis of lung cancer and even for the type of tumor. The positivity of CEA determined simultaneously in serum and in BAL of patients with lung cancer is higher than 80% whereas in patients with benign lung disease it is lower than 40%. The simultaneous assay of TPA in serum and in BAL showed 100% positivity in patients with oat-cell carcinoma, the frequencies of positivity were similar in patients with non-oat-cell carcinoma. For NSE and CanAg CA-50 patients with oat-cell carcinoma showed 100% positivity. Simultaneous assay of ferritin in serum and in BAL gave 85% positivity in patients with oat-cell carcinoma and only 23% in patients with non-oat-cell carcinoma. We conclude that the simultaneous determination of CEA and CanAg CA-50 or NSE in serum and in BAL is a useful aid in the diagnosis of lung malignancy.

Use of a specific oral hyposensitization therapy to Dermatophagoides pteronyssinus in children with atopic dermatitis.

The aim of the present study was to evaluate the efficacy of an oral specific hyposensitization therapy in children with atopic dermatitis and positive prick skin tests and/or RAST to Dermatophagoides pteronyssinus (D.pt.). A total of 60 patients, in three different clinical groups, were selected for a three years clinical trial. Group A: children with atopic dermatitis and allergic asthma and/or rhinitis; groups B and C: children with exclusively atopic dermatitis. Groups A and B received specific hyposensitization therapy. Group C was the control group. The clinical evaluation of the dermatological lesions, at the end of our study, didn't show any significant difference among the three groups. Moreover, the onset of respiratory symptoms between the two groups with exclusively atopic dermatitis was similar and not related to the positivity of prick skin tests and/or RAST to seasonal allergens. Our study suggests that specific hyposensitisation therapy with extracts of D.pt., although with no side effects, does not affect the natural history of atopic dermatitis.
