Thoracic lesions: diagnosis by ultrasound-guided biopsy.

We reviewed the results of US-guided fine-needle biopsies of peripheral pulmonary, pleural, mediastinal and chest wall lesions in 200 patients. Sufficient material for cytological analysis was obtained in 95%, 92%, 96% and 100%, respectively. Sensitivity was 88%, 94%, 96%, 100% and specificity 89%, 100% and 100%, respectively. The ratio of false-negative results was 7%. A cutting needle biopsy was additionally performed in 24 patients. All but two of the histological samples (92%) were adequate for diagnostic purposes and a correct diagnosis was established in 86% (19/22) of these. 8 patients (4%) with pleural or pulmonary targets had minor complications (5 pneumothorax, 3 haemoptysis), which did not require treatment. Cutting needle biopsies and biopsy of mediastinal lesions proved safe. Due to the many advantages US may be considered for guidance in peripheral larger-sized pulmonary lesions, particularly those abutting the pleura, and also in pleural, thoracic wall and mediastinal masses.

[Potentialities and limitations of sonographic diagnosis of the chest in childhood].

The advantages and limitations of the sonographic examination of the chest in 16 children are described. Partial opacification of the chest has been found in nine, a total "white" hemithorax in 7 children. Sonographic guided taps of the chest were performed in 3 children. Necessity, extent and yield of additional radiological examinations, especially computed tomography of the thorax, are discussed in detail.

Multifocal tuberculosis of the chest wall without pulmonary involvement.

Skeletal tuberculosis (TB) is usually seen in association with a primary pulmonary focus. However, it is being increasingly recognized that the former may be encountered without the latter, particularly in children. Sternal lesions have been frequently reported in infants, presumably secondary to Bacillus Calmette-Guerin (BCG) vaccination. Herein we report a case of rib TB and a cold abscess in a child who had previously had sternal TB ; that diagnosis had been missed at the time. Timely treatment of apparently solitary skeletal lesions may reduce the number of multifocal cases of skeletal TB in children.

Combined reconstruction of complex defects of the chest wall.

Defects of the chest wall are often encountered, and good results can be obtained both cosmetically and functionally from their treatment. We treated 13 patients with full thickness chest wall defects. Follow up ranged from 12 days to 19 months. Three had had recurrent breast carcinoma, seven relapse after excision of a sarcoma, two had had lesions of the chest wall after irradiation, and one had a sternal fistula. Local skin, musculocutaneous and free latissimus dorsi and anterolateral thigh flaps were done to cover soft tissue. Fascia lata, polypropylene (Marlex) mesh, and Marlex mesh-methylmethacrylate sandwich prosthesis, were used to stabilise the skeleton in nine patients. Two of the patients died postoperatively, one early. The use of Marlex mesh-methylmethacrylate sandwich prostheses for the stabilisation of the skeleton and local musculocutaneous flaps for covering soft tissues after resection of three or more ribs is effective.

Symptom frequency and severity in patients with metastatic or locally recurrent lung cancer: a prospective study using the Lung Cancer Symptom Scale in a community hospital.

PURPOSE: To define symptoms and therapeutic requirements for patients with metastatic or locally recurrent lung cancer. METHODS AND MATERIALS: Data were collected from 69 consecutive patients with locally advanced lung cancer seen in consultation at a radiation oncology facility serving a community hospital in Virginia. The Lung Cancer Symptom Scale, a validated quality of life instrument, measured the incidence of symptoms in this group. RESULTS: Average survival for the entire group was 7 months. Fifty-seven patients received 81 courses of radiation therapy, 33 directed at thoracic disease and 48 delivered to sites of metastasis. Thirty-three percent of those who received radiation therapy required treatment to more than one anatomic site. Every patient was symptomatic at the time of consultation, with the number (p = 0.001) and severity (p = 0.001) of symptoms they suffered worse in the patient group seen 0 to 3 months prior to death rather than 4 to 6 months prior to death. With the exception of cough, symptoms were marked in their severity. CONCLUSIONS: Patients with advanced lung cancer suffer frequent and severe symptoms that worsen in the final months of life. The appropriate timing and combination of radiotherapy and chemotherapy are yet to be resolved. Future studies will require use of validated quality of life instruments to better catalogue palliation and treatment toxicity.

Reconstruction of the chest wall with e-PTFE following major resection.

Nine patients underwent major chest wall resection at Thomas Jefferson University Hospital (Philadelphia, PA) over a 19-month period. Chest wall reconstruction was performed with an expanded polytetrafluoroethylene (e-PTFE) soft tissue patch (Gore-Tex) and vascularized flaps in all patients. The size of the skeletal defects ranged in area from 60 to 400 cm2. The primary indications for resection included chest wall sarcoma and radiation ulcer. Aggressive chest wall resection may be a patient's only opportunity for cure and an improved quality of life. In this series, chest wall resection was able to be performed with a low morbidity and no mortality. This study also demonstrates many of the advantages of e-PTFE as a chest wall substitute compared with other previously described prosthetic materials. The use of a Gore-Tex patch along with described flaps for soft tissue coverage provides good functional and aesthetic results.

Acute respiratory failure.

There appears to be a great similarity between all of the various types of Adult Respiratory Distress Syndromes (ARDS) in that they are all characterized by progressively increasing interstitial edema in the lungs and a reduced functional residual capacity. Early diagnosis is mandatory and therapy should be started as soon as there is a reasonable suspicion, based on the patient's injury or illness and the previous condition of his lungs, that acute respiratory failure is developing. Sepsis, shock, CNS or thoracic disease and trauma are important associated factors. Blood gas changes usually cannot be appreciated clinically until the respiratory problem is quite severe. Accordingly, serial blood gas analyses should be performed on any patient who has a reasonable chance of developing ARDS. We have found that changes in the estimated AaDO2 on room air are especially helpful. Any deterioration in the patient's clinical condition, blood gases or ventilatory effort should be considered as an indication for early ventilatory assistance. Control of the primary process, careful dehydration, high tidal volumes, and PEEP are the mainstays of therapy. Serial blood gases and careful observation of the patient's effective compliance are essential to determine the optimal ventilator setting and the optimal amount of PEEP. Recently intermittent mandatory ventilation (IMV) with very large amounts of PEEP have been reported to be of value. Early administration of massive steroids should be considered if the patient fails to respond promptly to correction of the underlying etiologic problem, particularly sepsis, careful progressive dehydration and optimal expansion of the alveoli, with high tidal volumes and PEEP.

Physiologic evaluation of noninvasive mechanical ventilation delivered with three types of masks in patients with chronic hypercapnic respiratory failure.

OBJECTIVE: The efficacy of noninvasive mechanical ventilation (NIMV) in improving breathing pattern and arterial blood gases (ABG) in hypercapnic patients has been well documented; however, little attention has been given to the choice of the interface and the ventilatory mode. We evaluated the effects of three types of masks and two modes of ventilation on patients' ABG, breathing pattern, and tolerance to ventilation. DESIGN: Prospective randomized study. SETTING: Two respiratory weaning centers. PATIENTS: A total of 26 stable hypercapnic patients (pH, 7.38 +/- 0.04; PaCO2, 59.2. +/- 10.9 torr) had not received NIMV and were affected by restrictive thoracic disease or obstructive pulmonary disease. INTERVENTIONS: Three 30-min runs of NIMV, delivered using volume-assisted (n = 13) or pressure-assisted modes of partial mechanical support (n = 13), were performed in random order with a full-face mask, a nasal mask, and nasal plugs. MEASUREMENTS: ABG, breathing pattern, and patients' tolerance to ventilation. MAIN RESULTS: Compared with spontaneous breathing, the application of NIMV significantly improved ABG and minute ventilation, irrespective of the ventilatory mode, the underlying pathology or the type of mask. Overall, a nasal mask was better tolerated than the other two interfaces (p < .005 vs. nasal plugs and full-face mask). PaCO2 was significantly lower (p < .01) with a full-face mask or nasal plugs than with a nasal mask (49.5 +/- 9.4 torr, 49.7 +/- 8 torr, and 52.4 +/- 11 torr, respectively). Minute ventilation was significantly higher with a full-face mask than with a nasal mask because of an increase in tidal volume. No differences were observed in tolerance to ventilation, ABG, or breathing pattern, using assist control or pressure-assisted modes. CONCLUSIONS: In this physiologic study, we have shown that in patients with hypercapnic respiratory failure, irrespective of the underlying pathology, the type of interface affects the NIMV outcome more than the ventilatory mode.

Computed tomographic evaluation of lesions in the thoracic apex.

Fifty patients with clinically suspected lesions of the chest apex underwent computed tomography (CT) and plain film (PF) examinations in an attempt to define the underlying etiology as benign or malignant. CT was slightly more sensitive in diagnosing malignancy (90%) compared with PF (77%), with a higher predictive value of a negative test (85% vs. 70%), although the differences were not statistically significant. The specificity and predictive value of a positive test were similar for CT and PF. CT's advantage was better elucidation of the soft tissues of the chest apex. CT provided additional information beyond PF in 17/20 patients with benign conditions and in 29/30 patients with cancer. In 21 of these 29 cancer patients, CT findings significantly altered subsequent management.

Pseudometastasis of the chest wall resulting from a Hickman catheter.

A 21-year-old woman with a high-grade soft-tissue sarcoma developed a lesion in the soft tissues of her chest wall at the same time that she developed pulmonary metastases from her primary neoplasm. The chest wall lesion diminished in size on sequential computed tomography (CT) scans, indicating that it was a pseudometastasis caused by removal of the patient's indwelling Hickman catheter. Awareness that removal of tunneled central venous catheters can produce soft-tissue masses in the chest wall that may mimic metastases may prevent inappropriate staging and treatment of these patients.
