OBJECTIVE: Defective ciliary ultrastructure and impaired mucociliary clearance play an important role in the development of respiratory disease and sinusitis. Changes in the ciliary ultrastructure of the sinonasal epithelium have been documented in patients with primary ciliary dyskinesia. However, secondary ciliary dyskinesias and epithelial cytopathologic changes have been underappreciated as ...

Both humoral and cell-mediated autoimmune mechanisms have been implicated in the pathogenesis of Guillain-Barré syndrome (GBS). Therefore, its occurrence in severely immunocompromised patients is not expected. We identified 3 severely immunocompromised patients who developed GBS. Two of the 3 patients had acquired immunodeficiency syndrome with CD4 counts of 5 and ...

Autoimmune haemolytic anaemia (AIHA) is one of the major complications in chronic lymphocytic leukaemia (CLL). Treatment with alkylating agents and the adenosine analogue, fludarabine, might trigger the development of AIHA in CLL patients despite the reduction of leukaemic clone. The influence of 2-chlorodeoxyadenosine (2-CdA) on AIHA in patients with CLL ...
