Evaluation of postoperative hearing acuity and equilibrium was performed in eight patients with labyrinthine fistula caused by cholesteatoma, in which at least one of the semicircular canals (five cases, lateral; one case, superior; one case, posterior; and one case, both lateral and superior) was interrupted during eradication of the matrix and(More)
In a previous study, we demonstrated the benefit of tonsillectomy for early recovery from Henoch-Schönlein purpura (HSP) nephritis (HSPN), suggesting the pathological role of tonsils in HSP (Inoue et al., Clin Nephrol 67:298–305, 2007). In this study, we evaluated the efficacy of extensive eradication of infectious foci directly connected to the tonsils,(More)
Henoch-Schönlein purpura (HSP) and IgA nephropathy (IgAN) are both IgA1-related vasculitis caused by vascular deposition of IgA1-containing immune complexes. A pathological role of the tonsils in the development of HSP and IgAN has been suggested. Tonsils are a mucosaassociated lymphoid organ. Since oral and sinonasal cavities are anatomically directly(More)
It is hypothesized that blockade of the tympanic isthmus causes isolation of the attic and the adjacent middle ear spaces and that subsequent building up of the negative pressure in these spaces results in retraction of the pars flaccida, leading to formation of attic retraction pockets and cholesteatomas. To examine this theory, computerized tomographic(More)
We report 6th case of carcinoid tumor of the middle ear in a 16-year-old man. The clinical, histologic, immunohistochemical and ultrastructural features are discussed. The tumor in the attic and the tympanic cavity was successfully excised by radical mastoidectomy. Microscopically, the argyrophilic property and neurosecretory granules which are(More)
BACKGROUND We previously reported the efficacy of extensive eradication of infectious foci in oral and ENT lesions, combined with tonsillectomy plus methylprednisolone (MP) pulse therapy, for curing pediatric Henoch-Schönlein purpura (HSP) and HSP nephritis. In the present study, we used this therapy in patients with pediatric IgA nephropathy (IgAN) to(More)
To determine the effects of politzerization or middle ear (ME) inflation by a catheter, we studied the membranes (29 patients). Serial tympanometries were performed prior to the ME inflation and immediately, 10, 20, 30 and 60 min after the procedure. The present study showed that the more negative the ME pressure was before the inflation, the greater the(More)
