Spondylodiscitis after bilateral sequential lung transplantation in a patient with cystic fibrosis.

We report the case of a 24-year-old woman with cystic fibrosis in whom spondylodiscitis developed after bilateral sequential transplantation. The diagnostic work-up included magnetic resonance imaging, computed tomography-guided disk biopsy, histological examination, and cultures of disk specimens. The infective organism was D group Streptococcus and the patient was successfully treated with intravenous piperacillin followed by oral ampicillin. To our knowledge, this is the first reported case of spondylodiscitis after lung transplantation.

[An appendiceal-vesical fistula in a patient with cystic fibrosis]. / Fistola appendico-vescicale in un malato di fibrosi cistica.

Cystic fibrosis is an hereditary disease in which abnormally viscous secretion of exocrine glands causes chronic pulmonary infections and gastrointestinal disorders. The authors report the case of a patient with cystic fibrosis and appendicitis complicated by appendico-vesical fistula. The appendico-vesical fistula has been described during appendicitis; its association with the cystic fibrosis however has never been reported in the literature.

Chronologic milestones in cystic fibrosis (CF) are reported. The value of the sweat test and the most recent advances on neonatal CF screening are described.

Gallstones in cystic fibrosis: a critical reappraisal.

Radiolucent gallstones are common in young adults with cystic fibrosis. In the mid-1970s, it was suggested that gallstones are made of cholesterol, but this hypothesis has never been tested. Several recent studies have shown that the detection of cholesterol monohydrate crystals in bile has high sensitivity and specificity for the diagnosis of cholesterol gallstones. We therefore used this approach to study 17 young adults with cystic fibrosis, 10 of whom had radiolucent gallstones. The two groups of patients were comparable in age and gender (all patients but one were male). Duodenal bile was obtained after gallbladder contraction with intravenous cerulein; it was used for lipid and protein chemistry studies and for polarizing microscopy. The latter was performed both in whole bile and in the postultracentrifugation (100,000 g) sediment. Bile cholesterol saturation did not significantly differ between patients with (1.21 +/- 0.28) or without gallstones (0.99 +/- 0.54). Slight cholesterol supersaturation was found in 7 of 10 gallstone and three of seven nongallstone patients. At no time were cholesterol crystals detected in either the group, even after bile ultracentrifugation. Two more cystic fibrosis patients with gallstones died of severe bronchopneumopathy, and small pigment gallstones were obtained at autopsy. At stone analysis, cholesterol content was 44% and 28% of dry weight, respectively. Infrared spectroscopy of stone powder was compatible with the presence of calcium bilirubinate and proteins as major components. We conclude that radiolucent gallstones of cystic fibrosis are not of the conventional cholesterol type.
