1/213. Surgical findings in idiopathic trigeminal neuropathy mimicking a trigeminal neurinoma.

    Idiopathic trigeminal neuropathy is a benign disorder where the main clinical feature is facial numbness limited to the territory of one or more divisions of the trigeminal nerve, persisting for a few weeks to several years and in which no underlying disease can be identified. The case of a 37-year-old man with a brief history of sensory and motor trigeminal symptoms who showed magnetic resonance imaging (MRI) findings consistent with a small trigeminal neurinoma is reported. The patient was operated on but no tumour could be found during surgery and a biopsy was taken from the portio major. Pathological diagnosis was chronic non granulomatous inflammatory reaction with areas of coagulation necrosis. Control MRI showed complete resolution of the trigeminal abnormalities. It is concluded that in patients with MRI findings suggestive of a small trigeminal schwannoma, benign idiopathic trigeminal neuropathy should also be considered in the differential diagnosis. A conservative approach with sequential MRI studies may avoid an unnecessary surgical exploration. ( info)

2/213. Delayed facial paralysis after stapedotomy using KTP laser.

    OBJECTIVE: Delayed facial paralysis after stapes surgery is uncommon and has been reported after traditional, nonlaser techniques for stapedotomy. The purpose of this paper is to inform the reader of the potential risk of delayed facial nerve paralysis associated with the use of the potassium titanyl phosphate (KTP) laser for stapedotomy. Etiologic mechanisms are discussed. STUDY DESIGN: The study was a descriptive study-case report. SETTING: The study was conducted at a university-based otologic practice. patients: Two patients with otosclerosis and delayed onset facial palsy 5 to 7 days after uncomplicated stapedotomy using the KTP laser were included in the study. INTERVENTION: potassium titanyl phosphate laser stapedotomy was performed. patients received treatment of facial palsy with a tapering course of oral steroids. MAIN OUTCOME MEASURE: House-Brackmann facial nerve grade scores were used. RESULTS: Improvement of House-Brackmann facial nerve scores from Grade VI to Grade I-II in one patient, and improvement from Grade IV to Grade I-II in the other was seen. CONCLUSION: The probable etiology of delayed facial palsy is viral neuritis from reactivation of dormant virus within the facial nerve, initiated by thermal stress of the KTP laser. Presentation and resolution of the facial palsy is similar to other types of delayed facial palsy resulting from nonlaser techniques of stapes surgery and other types of middle ear and neurotologic surgeries previously reported.

3/213. Herpetic tracheitis and brachial plexus neuropathy in a child with burns.

    Herpetic tracheobronchitis is a well-recognized clinical entity that most commonly occurs in immunocompromised patients, including patients with burns. Although the diagnosis of herpetic tracheobronchitis is usually not made until postmortem examination, the presence of the condition can be established when histologic specimens of a patient with upper airway obstruction are studied. In this article, a case is described in which a child developed herpetic tracheitis after undergoing elective intubation after the grafting of burns of the face, neck, and upper extremity. The tracheitis resulted in severe upper airway obstruction that required tracheal dilatation and sequential bronchoscopic excisions of granulation tissue. The patient also developed a brachial plexus neuropathy that was most likely related to herpetic infection. ( info)

4/213. Isolated neuritis of the sciatic nerve in a case of lyme disease.

    lyme disease is an infectious disease caused by the spirochete borrelia burgdorferi. The course of the disease is divided into three stages, the second of which may include various types of peripheral nervous system disturbances. We report the case of a patient with persistent deficits caused by the prevalent involvement of the sciatic nerve, confirmed by electrophysiological and neuropathological findings. The most significant bioptic results were axonal degeneration and perivascular inflammation. Damage to a single peripheral nerve as the dominant clinical expression during the course of lyme disease is an unusual finding that has been rarely described in the literature. ( info)

5/213. Migrant sensory neuropathy: report of 5 cases and review of the literature.

    There are only a few case descriptions of migrant sensory neuropathy. We report the clinical, laboratory, and electrophysiological findings observed in 5 patients whose presentation conformed with Wartenberg's description of a chronic, disseminated migrant sensory mononeuritis. In one patient, intermittent cranial motor nerve involvement occurred as well. The sural nerve biopsy in this patient showed changes suggestive of focal ischemic nerve damage and electron microscopy confirmed a vasculopathy. ( info)

6/213. Management of foot pain associated with accessory bones of the foot: two clinical case reports.

    STUDY DESIGN: Case study. OBJECTIVES: To discuss the differential diagnosis, the nonsurgical and postoperative management of common accessory bones of the foot. BACKGROUND: Accessory bones of the foot that are formed during abnormal ossification are commonly found in asymptomatic feet. Two of the most common accessory bones are the accessory navicular and the os peroneum. Their painful presence must be considered in the differential diagnosis of any acute or chronic foot pain. The optimal treatment for the conservative and postoperative management of painful os peroneum and accessory navicular bones remains undefined. methods AND MEASURES: Therapeutic management of the fractured os peroneum included bracing, taping, and foot orthotics to allow healing of involved tissues, and stretching. The focus of the postoperative management of the accessory navicular was joint mobilization and progressive strengthening. Dependent variables included level of pain with provocation and alleviation tests of joint and soft tissue; girth and sensory tests of the foot and ankle; goniometric measures of foot and ankle; strength of ankle and hip muscles; functional tests; and patient's self-reported pain status. RESULTS: The patient with the fractured os peroneum was treated in 13 visits for 10 weeks. At discharge from physical therapy, the patient had the following outcomes relative to the noninvolved side: 100% return of normal sensation tested by light touch and vibration; pain decreased from 6/10 to 1/10; 100% reduction of swelling with ankle girth to normal; 100% range of motion of ankle and subtalar joints. Strength in plantar flexion and eversion remained 20% impaired (80% return to normal) secondary to pain. Upon discharge, he still reported mild pain when walking but was able to return to previous leisure activities. The second patient with the accessory navicular was treated in 18 visits over 9 weeks. Relative to the uninvolved side, she was discharged with the following: 70% return of range of motion in the foot and ankle, 100% of strength in hip and ankle, and 100% return of balance. She could squat and jump without pain and she returned to full premorbid activity level. CONCLUSIONS: Rehabilitative management of both cases addressed specific impairments and was successful in improving the patients' activity limitation. Clinicians should be aware that these accessory bones are possible sources of disability, secondary to foot pain. ( info)

7/213. Ski boot compression syndrome.

    The extensor tendons and peroneal nerve can be compressed at the ankle by the tongue of the ski boot. The resulting neuritis and synovitis may be severe enough to mimick an anterior compartment syndrome. Treatment consists of conservative methods but the paresthesiae may remain for long periods of time. ( info)

8/213. Wartenberg's migrant sensory neuritis.

    We describe a patient with the sudden onset of a painful, purely sensory, mononeuritis multiplex. Investigations showed no evidence for any underlying systemic condition. A nerve biopsy showed fascicular wallerian degeneration with perineurial thickening, inflammatory cells, and immunoglobulin g (IgG) deposition. His painful sensory deficits persisted, with no improvement after treatment with prednisone. The clinical characteristics in this case were very similar to those originally described by Wartenberg, and subsequently by other investigators. The investigations in our case strongly suggest that there may be an underlying immune pathogenesis for cases of Wartenberg's migrant sensory neuritis. ( info)

9/213. "Pseudo-conduction block" in a patient with vasculitic neuropathy.

    A 63-year-old man presented with progressive asymmetric weakness and numbness in his hands of 2 weeks duration. Nerve conduction studies showed low amplitude motor evoked potentials of both median nerves. The right ulnar, left tibial and peroneal nerves had normal potentials on distal stimulation with markedly decreased amplitudes proximally, suggestive of "conduction block". Three weeks later, amplitudes were decreased throughout. The patient was diagnosed with vasculitis. The acute ischemic injury presumably resulted in axonal damage between the distal and proximal stimulation sites, with subsequent wallerian degeneration. ( info)

10/213. A case of Dejerine-Sottas disease with schizophrenic symptoms. A clinical and pathological study.

    A case of hypertrophic interstitial neuritis with a disturbance of intelligence and schizophrenic symptoms was reported. The patient, a 41-year-old male, showed monologia at the age of 14 and auditory hallucination at the age of 21. He was diagnosed as schizophrenia. Torsion of the head to the right side and muscular atrophy were also noticed at 21 years. Atrophy of the muscles progressed gradually, particularly in the distal parts of the upper and lower extremeties. Psychiatric examination revealed schizophrenic symptoms such as auditory hallucination, thought disorder, lack of spontaneity, autism, apathy, etc. There was also a disturbance of intelligence (imbecility). In neurological examination, the torsion of the head to the right side, slight exaggeration of the peripheral reflexes, muscular atrophy in the distal parts of the extremeties were noted. The bilateral ulnar nerves were markedly hypertrophied. The biopsy of the right ulnar nerve revealed a remarkable thickening of the endoneuria and "onion bulb" formations. A large amount of the interstitial accumulation of PAS positive substance, which showed metachromasia in cresyl violet staining, was also noted. Schwann cell processes were proved electron-microscopically to surround the myelin sheaths and some of them meandered and extended and into the metachromatic substance. The basement membrane of the sheath cell was hypertrophic in some portions and elongated into interstitium. The nucleus of the sheath cell was hyperchromic and showed marked atrophy. Histological examination of the biopsy specimen obtained from the gastrocnemius muscle suggested neurogenic muscular atrophy. The relationship among the hypertrophic interstitial neuritis, schizophrenic symptoms, disturbance of intelligence and torsion of the head was also discussed. ( info)
