A randomized trial of adoptive immunotherapy with tumor-infiltrating lymphocytes and interleukin-2 versus standard therapy in the postoperative treatment of resected nonsmall cell lung carcinoma.

Background: A previous pilot study from our group suggested that: (1) adoptive immunotherapy (A1) with tumor-infiltrating lymphocytes (TIL) and recombinant interleukin-2 (rIL-2) may be applied with safety to more than 80% of the patients who had surgery for Stage III nonsmall cell lung carcinoma (NSCLC); and (2) AI could be useful in patients with locally advanced disease. The present randomized study was planned to assess the efficacy of AI in the postoperative treatment of Stage II, IIIa, or IIIb NSCLC:

Methods: TIL were expanded in vitro from tissue samples obtained from the surgically removed specimens of 131 patients. Eighteen cultures yielded no growth of TIL.

Remifentanil reduces auditory and somatosensory evoked responses during isoflurane anaesthesia in a dose-dependent manner.

We studied 60 patients during stable isoflurane anaesthesia (0.4 MAC) after premedication with temazepam. Patients were allocated randomly to one of three dose regimens of remifentanil: 1 microgram kg-1 i.

Comparison of cervical magnetic stimulation and bilateral percutaneous electrical stimulation of the phrenic nerves in normal subjects.

Cervical magnetic stimulation is a new technique for stimulating the phrenic nerves, and may offer an alternative to percutaneous electrical stimulation for assessing diaphragmatic strength in normal subjects and patients in whom electrical stimulation is technically difficult or poorly tolerated. We compared cervical magnetic stimulation with conventional supramaximal bilateral percutaneous electrical stimulation in nine normal subjects. We measured oesophageal pressure (Poes), gastric pressure (Pgas) and transdiaphragmatic pressure (Pdi).

A comparison of different modes of noninvasive ventilatory support: effects on ventilation and inspiratory muscle effort.

The aims of noninvasive ventilation include the correction of hypoventilation and unloading of inspiratory muscles. Volume cycled flow generators, bi-level positive airway pressure and continuous positive airway pressure techniques have all been used with face and nasal masks. We have compared these modes of ventilatory support, administered by a nasal mask in stable, awake outpatients with chronic obstructive pulmonary disease or neuromusculo-skeletal disease in respect of their effects on ventilation, inspiratory muscle effort and oxygen saturation.

Portable measurement of maximum mouth pressures.

We have compared a small portable mouth pressure meter (MPM) to our laboratory standard (LS) pressure recording equipment in order to evaluate this new device. The mouth pressure meter measures and displays as a digital read-out peak pressure for inspiratory and expiratory efforts. It samples the signal at 16 Hz, and an integral microprocessor is programmed to determine and display the maximum pressure averaged over one second both during inspiratory and expiratory manoeuvres (PImax and PEmax, respectively).

Diaphragmatic dysfunction in neuralgic amyotrophy: an electrophysiologic evaluation of 16 patients presenting with dyspnea.

We report 16 adult men (age, 41 to 75 yr) with neuralgic amyotrophy (NA) who presented with dyspnea due to involvement of the diaphragm. All patients developed breathlessness after a prodrome of acute severe neck and shoulder pain. Bilateral diaphragm paralysis (BDP) was confirmed in 12 patients and unilateral diaphragm paralysis (UDP) in four by the absence of electrical and mechanical responses to percutaneous phrenic nerve stimulation.

[Trials of the diagnostic potentials of TPA in tumorous and nontumorous lung pathologies in 303 cases].

Serum tissue polypeptide antigen (TPA) has been determined in 271 patients with pleural or pulmonary neoplastic diseases (131) or with benign lung diseases (140). Using a cut-off of 95 U/L, TPA has a sensitivity and specificity of 65%. Therefore, TPA serum determination can suggest a diagnosis of malignancy, but its evaluation, as a single test, is not useful to differentiate between malignant or benign disease.

Bacampicillin and the immune response.

To evaluate the possible influence of a bacampicillin on the immune response, 16 subjects, out of a group of 60 patients with bacterial respiratory tract infections, had various tests of immune function determined, before and after treatment. The peripheral mononuclear blastogenic index (ratio between PHA-induced and spontaneous proliferation), PHA-induced interferon-gamma production, percentages of T and B lymphocytes, serum immunoglobulins (IgG, IgM, IgA) levels, failed to show any significative differences before and after the treatment with bacampicillin. The PHA-induced interleukin-2 production increased after treatment but just failed to reach statistical significance (0.

Protective effect of Duovent versus salbutamol in long-term treatment.

The effect of the combination fenoterol-ipratropium bromide (Duovent) as a bronchodilator drug versus salbutamol and placebo was investigated in 20 patients with chronic obstructive lung disease in a random cross-over trial. Our study was performed not only to evaluate the bronchodilator response, but especially to quantify the possibly more prolonged action of Duovent versus salbutamol, based on registration of prevention of asthma attacks, time effects and protective activity, management and tolerance. Each patient received therapy for 3 weeks; in each week only one of the preparations: salbutamol, Duovent or placebo was used.
