Data of 38 patients with primary tonsil lymphoma, treated during the past 14 years was analysed. All cases were non-Hodgkin lymphomas. There were 11 patients with Stage 1, 14 with Stage II, 8 with Stage III, and 4 with Stage IV tonsillar lymphomas. The applied chemotherapies were CHOP or MACOP-B regimen. The overall 5-year survival rate was 64.4%. Further(More)
The post-operative outcome of hearing, the reconstructed external auditory canal, and the state of the reconstructed middle-ear cavity after canal wall down tympanoplasty with canal and attico-antrum reconstruction was studied in 103 ears with middle-ear cholesteatoma. The reconstructed mastoid cavity was re-aerated in 36.5 per cent of the cases, which was(More)
The goal was to determine how the facial nerve path forms normally through the ear region. Five three-dimensional computer reconstructions and eight wax plate-graphic, two-dimensional reconstructions were made from a group of 47 serially sectioned human embryos that were in the blastemal period of ear development, when most of the definitive arrangement is(More)
Our objective is to study the neurological characteristics of medial area infarction in the caudal cerebellum. Medial area of the caudal cerebellum is supplied with 2 branches of the posterior inferior cerebellar artery (PICA). The medial hemispheric branch of the PICA distributes to the medial area of the caudal cerebellar hemisphere. The medial branch of(More)
OBJECTIVES Most tracheobronchial foreign bodies in children are radiolucent, and accurate diagnosis of such foreign bodies is not always easy. This can result in delay of diagnosis or misdiagnosis of foreign body aspiration. We report the usefulness and pitfalls of use of digital subtraction fluoroscopy (DSF) to diagnose radiolucent aspirated foreign bodies(More)
Glossopharyngeal and/or vagus nerve involvement is infrequent in patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). We herein report the case of a 69-year-old Japanese woman who presented with muscle weakness and numbness of the extremities with dysphagia. The serum anti-ganglioside GM1 immunoglobulin IgM antibody levels were(More)
The present experiment was designed to determine which neurotransmitter influences the burst pattern in the firing of the inhibitory burst neurons (IBN) during vestibular nystagmus. Cats were anesthetized with ether and mounted in a stereotaxic apparatus on a turntable, implanted stimulation electrodes, removed occipital bone and aspirated the vermal part(More)
A neuro-otological examination was given to 22 patients with paroxysmal positional vertigo within 1 week of head injury. In all cases, reverse rotatory positional nystagmus accompanied by a vertiginous sensation was observed in the positional nystagmus test. No relationship between the affected side and the direction of eye movement in the head-hanging(More)
Scanning electron microscopic observation of the transtympanic infusion of 10% xylocain revealed twisting and disorders of outer hairs especially from the 2nd and 3rd rows of the basal to the 2nd turn of the organ of Corti, and adhesion and fusion of the sensory hairs of the crista ampullaris and otolith organ 1 and 4 days after injection. Four percent(More)
