[Comparison of mouth pressure, twitch, after anterior magnetic stimulation against posterior magnetic stimulation in healthy subjects].

BACKGROUND: If techniques for studying respiratory muscle function are easy to use and well tolerates by patients, they can be used routinely. Measuring mouth twitches (TwM) using either bilateral anterior or posterior magnetic stimulation meets both criteria. SUBJECTS AND METHODS: We studied 16 healthy subjects. TwM was measured using bilateral anterior (TwMA) and posterior (TwMP) stimulation. Ten stimuli were applied for each technique for each subject. Five subjects repeated the test was repeated on a different day. RESULTS: The mean TwMA in healthy subjects was 21.07 +/- 4.4 cmH2O (range 13.72-30.11); the mean TwMP was 21.12 +/- 5.9 cmH2O (range 12.7-35.7) (NS). The mean difference was 2.8 +/- 2.5 cmH2O, while the ratio TwMP/PImax was 0.15 (range 0.08-0.10) and TwMA/PImax was 0.14 (range 0.07-0.15). The correlation between the two technique was 0.8. The patients who underwent testing twice had a mean TwMA of 20 cmH2O on the first day and 10.18 cmH2O on the second (NS). The coefficient of variation (CoV%) was 5.9% for TwMA and 7.2% for TwMP. CONCLUSIONS: The two techniques for measuring TwM give similar results and coefficients of variation in healthy subjects; either technique can be used. Variation from one testing day to another is low.

[Mediastinal liposarcoma. A report of 2 cases].

Liposarcomas are malignant mesenchymal tumors whose primary location in the mediastinum is rare. We report two cases of mediastinal liposarcoma, describing the clinical signs and radiologic features found and the diagnostic procedures performed. The significance of histologic variability as a factor that conditions treatment and prognosis is underlined.

[Skin tumor as presentation form of lung actinomycosis].

We report three cases of thoracic actinomycosis whose symptoms were cutaneous tumors on the thorax. Clinical signs and images are described, along with diagnostic procedures. The excellent outcome after antibiotic treatment, which must last at least 6 months, is emphasized as well as the need to keep this disease in mind when certain symptoms and images coincide.

[Protected bacteriologic brushing in patients with severe copd].

To determine the presence of germs and their concentration in a group of patients with severe chronic obstructive pulmonary disease (COPD) (FEV1 < 50%), some of whom were in stable condition and others of whom were in acute phase. Twenty-six patients with severe COPD (14 stable and 12 acute phase) were enrolled. None had received prior antibiotic or corticoid treatment. The stable patients had no signs or symptoms of exacerbation, whereas the acute-phase patients had increased dyspnea, sputum volume and purulence. The patients received aerosol rather than liquid anesthesia when PSB sampling was performed. A PSB finding was considered positive at a level > or = 10(3) CFU/ml. There were no significant differences between the groups with respect to age, sex, proportion of smokers and ex-smokers or packs per year. The only spirometric measure that was significantly different was (FEV1/FVC, which was lower in the acute-phase group (p < 0.05). Positive PSB findings were recorded for 57.1% of the stable patients and for 66.7% of the acute-phase patients (p = NS). H. influenzae was the microorganism found most often in both groups. The mean CFU/ml level was 8,625 in stable patients and 17,375 in acute-phase patients (p = NS). A large proportion of stable patients (57.1%) with severe COPD harbor significant concentrations of germs as revealed by PSB sampling. Germ concentrations were found in a non significantly greater number of acute-phase patients, confirming the lack of congruence between clinical status and bacteriological condition.

Persistence of müllerian derivatives, lymphangiectasis, hepatic failure, postaxial polydactyly, renal and craniofacial anomalies.

We describe 3 unrelated newborn males with a previously unreported constellation of congenital anomalies. All 3 died neonatally of hepatic failure. Clinically, they presented with a pattern of malformations characterized by prenatal linear growth deficiency, hypertrophied alveolar ridges, redundant nuchal skin, and postaxial polydactyly. All 3 cases had male external genitalia with cryptorchidism, and 2 of them, a small penis. Necropsies showed similar internal anomalies, consisting of müllerian duct remnants, lymphangiectasis, and renal anomalies. The karyotypes were normal (46, XY) in skin fibroblasts (Case 1) and in peripheral blood lymphocytes (Case 3). Although this pattern of congenital anomalies must be differentiated from several other lethal syndromes, to our knowledge, no similar cases have been described previously. Cause of this syndrome is unknown. Because Case 2 had a previous brother with similar anomalies, we suspect that this new entity probably is an autosomal recessive or X-linked trait.
