ABSTRACT

An increase in incidence of malignant pleural mesotheliomas has been noted recently. In order to assess our own experience, we reviewed all medical records and biopsies of patients who were seen with this diagnosis in Hospital Maria Ferrer between January 1986 and December 1997. Clinical data of 17 patients were analyzed. Mean age was 59 years, 76% were male. Industrial or environmental exposure to asbestos was established in 9 patients (53%). Most common symptoms at presentation were dyspnea (88%) and chest pain (65%). Pleural thickening with or without effusion was the usual finding in chest X rays and CAT scans. Biochemical analysis of pleural fluids was consistent with exudate. Diagnosis was performed by thoracotomy (47%), needle biopsy (23.5%) and videothoracoscopy (29.5%). Histological samples were available for review in 16 of the 17 patients: they were epithelial (10), sarcomatoid (2) and mixed tumors (4). Treatment reflected varying approaches. Palliative methods (pleurodesis, chemotherapy and radiotherapy) were preferred at the beginning while more aggressive interventions are performed nowadays. Pleuroneumonectomy alone or in combination with other therapies was carried out in 5 patients with no operative mortality although some complications occurred such as empyema, bronchopleural fistula and severe chest pain. Survival rate for all groups was 10.5 +/- 5.9 months. However, the mean survival of patients who underwent surgery was 17.5 +/- 2.1 months (p < 0.04) with an associated improvement in quality of life. Therefore, we consider that surgery associated with other therapies offers at present, the best therapeutic option for this bad prognosis condition.

ABSTRACT

Two patients suspected of suffering from ciliary dyskinesis were investigated. They consulted for primary infertility and chronic respiratory disease. Functional lung studies showed obstructive changes in one patient. Both had immotile sperm with short, thick and rigid tails. Ultrastructural studies of nasal biopsies showed abnormal cilia with almost complete lack of inner dynein arms (mean number of inner arms per axoneme 0.67 +/- 1.21 in patient 1 and 1.49 +/- 1.17 in patient 2, compared with normal values of 5.3 +/- 0.13). Other abnormalities included lack of parallel orientation of cilia and central translocation of microtubular doublets. Electron microscopy of sperm revealed hyperplasia of the fibrous sheath and axonemal disruption. This is the first report of an association of different anomalies in cilia and flagella leading to clinical manifestation of the immotile cilia syndrome. These findings emphasize the need for ultrastructural examination of respiratory cilia in men suffering from fibrous sheath alterations of sperm which so far have not been described in patients with the classical form of immotile cilia syndrome.
