Chest ultrasonography to assess the kinetics and efficacy of talc pleurodesis in a model of pneumothorax: an experimental animal study.

Talc pleurodesis is used to avoid recurrences in malignant pleural effusions or pneumothorax. The lack of lung sliding detected by chest ultrasonography (CUS) after talc application is indicative of the effectiveness of pleurodesis. The objective of our study was to explore, in an animal model, the capacity of CUS to predict the quality of a symphysis induced by talc poudrage (TP) and talc slurry (TS).

[An experimental study on the systemic distribution of calibrated talc after intra-pleural injection].

Introduction: Among the agents used to produce pleural symphysis talc is the most effective and least expensive. However, its use is controversial on account of the description of respiratory complications associated with subsequent systemic spread of the talc particles. This hypothesis rests on clinical and experimental observations of talc particles in the viscera.

[Four years of screening cervical smears of cervical lesions].

Twelve thousand two hundred and eighty nine Pap smears were collected from public hospitals and from private practices during a four year period (January 1987 to December 1990). 4.2% of Pap smears exhibited condylomatous or dysplastic lesions.

Early transient ultrastructural and quantitative changes in nucleolar vacuoles of sympathetic neurons in isolated superior cervical ganglion of the rat.

Nucleolar changes and their time-course following axotomy and decentralization were investigated using an ultrastructural and stereological analysis of sympathetic neurons in superior cervical ganglion. By comparison with ganglia fixed immediately after removal, incubation for 2 h, 3 h and 5 h in NCTC 109 medium at 37 degrees C was found to induce early changes in the nucleolar volume (first a 33% increase, followed by a 43% decrease and a subsequent recovery to control values after 5 h). Moreover, dense material (also called 'microspherules') appeared in nucleolar vacuoles as early as 2 h after the beginning of incubation and was present after 3 h, but disappeared after a 5 h incubation.

[Lipid pneumopathy and bronchopulmonary adenocarcinoma. Apropos of a case].

The authors report a case of a patient aged 83 who presented with a lipid pneumonia and a primary broncho-pulmonary adenocarcinoma of the left lower lobe. The diagnosis of the lipid pneumonia was confirmed following broncho-alveolar lavage and the autopsy confirms the neoplastic origin of the mass lesion at the left base. The authors report 16 similar cases in the literature between 1943 and 1989.
