title: [A case of immotile cilia syndrome and a review of Japanese cases].
abstract: A case of immotile cilia syndrome (ICS) is presented. A 34-year-old male, who had suffered from recurrent bronchitis, sinusitis and otitis media since early childhood, was admitted to Keio University Hospital complaining of productive cough and infertility. A saccharin test showed prolonged nasal clearance time, and semen analysis revealed immotile sperm. By electron microscopic observation of cilia of the nasal mucous epithelium and the sperm, inner and outer dynein arm defect, abnormal microtubular arrangement and compound cilia were detected and he was diagnosed as ICS. Thirty eight Japanese cases of ICS collected from the literature were analyzed concerning clinical manifestations, airway clearance, family history and ciliary ultrastructural abnormalities (Table 2, 3). Recurrent bronchitis, male infertility, chronic sinusitis, otitis and decrease in airway clearance were very common in these patients. Female infertility was more common than anticipated. The prevalence rate of situs inversus was more than 50%, probably due to more attention having been paid to Kartagener's syndrome in Japan. Recent studies show that the cilia of this syndrome is not always immotile but characterized by hypomotility or asynchrony, and have attempted to determine the relationship between each ciliary ultrastructural abnormality and motility pattern. It is necessary that more patients including incomplete and mild cases should be investigated.
