Isolated infiltrative endometriosis of the sciatic nerve: a report of three patients.
2007
Objective: To report that isolated endometriosis of the sciatic nerve without further manifestation of endometriosis does exist. Design: We describe our technique of laparoscopic neurolysis of the sciatic nerve and the sacral plexus. Setting: Department of Gynecology and Obstetrics, St. Elisabeth Hospital, affiliated with the University of Cologne, Cologne, Germany. Patient(s): Three female patients with isolated endometriotic infiltration of the endopelvic portion of the sciatic nerve. Intervention(s): Elective laparoscopic neurolysis of the sciatic nerve with removal of endometriosis. Main Outcome Measure(s): Disparition of pain in the patients and histologic information of the endometrio…
Facial disability index (FDI): adaptation to Spanish, reliability and validity.
2011
Objectives: To adapt to Spanish the facial disability index (FDI) described by VanSwearingen and Brach in 1995 and to assess its reliability and validity in patients with facial nerve paresis after parotidectomy. Study Design: The present study was conducted in two different stages: a) cross-cultural adaptation of the questionnaire and b) cross-sectional study of a control group of 79 Spanish-speaking patients who suffered facial paresis after superficial parotidectomy with facial nerve preservation. The cross-cultural adaptation process comprised the following stages: (I) initial translation, (II) synthesis of the translated document, (III) retro-translation, (IV) review by a board of expe…
Semaphorin and plexin gene expression is altered in the prefrontal cortex of schizophrenia patients with and without auditory hallucinations
2015
Auditory hallucinations (AH) are clinical hallmarks of schizophrenia, however little is known about molecular genetics of these symptoms. In this study, gene expression profiling of postmortem brain samples from prefrontal cortex of schizophrenic patients without AH (SNA), patients with AH (SA) and control subjects were compared. Genome-wide expression analysis was conducted using samples of three individuals of each group and the Affymetrix GeneChip Human-Gene 1.0 ST-Array. This analysis identified the Axon Guidance pathway as one of the most differentially expressed network among SNA, SA and CNT. To confirm the transcriptome results, mRNA level quantification of seventeen genes involved i…
Effects of contralateral white noise stimulation on transitory evoked otoacoustic emissions in patients with acoustic neuroma.
1995
Abstract Transitory evoked otoacoustic emissions are normal phenomena observed in most persons with hearing levels greater than 35 dB. Further, masking of the contralateral ear produces amplitude reductions in the transitory evoked otoacoustic emissions. We have undertaken a study of transitory evoked otoacoustic emissions in 20 patients with acoustic neuroma. All patients were assessed for transitory evoked otoacoustic emissions bilaterally, with and without contralateral masking with white band noise at 40, 50, and 60 dB. We found that transitory evoked otoacoustic emissions were present in 30% of ears with tumor and that the presence of transitory evoked otoacoustic emissions is associat…
Anterior fusion for cervical spondylosis
1978
Anterior fusion was performed on 138 patients as treatment for degenerative changes of the cervical vertebral column. The results were checked after up to 11 years in 122 patients and were found to be good in 55%, fair in 3895% and poor in 6.5%. There were complications of phonetic paralysis in one case, Horner syndrome in two cases, 2 wound infections, and complaints about the iliac crest in 3 patients. Kyphosis at the fused segment occurred 26.1% of cases, the average angle being 15.3 degrees, but it did not influence the clinical results. Mortality was 2%. Inadequate visualization of the nerve roots at operation was probably the reason for the segmental deficits and suggestions were made…
Myasthenia gravis associated with Charcot-Marie-Tooth neuropathy: report of a case
1992
We report the case of a 24 year old woman who developed myasthenia gravis in the course of a mild form of Charcot-Marie-Tooth neuropathy. We describe the clinical manifestations together with the neurophysiological, pathological, serological findings and response to therapy and discuss the unusual association in the light of the relevant literature. © 1992 Masson Italia Periodici S.r.l.
Impaired refractory periods of peripheral sensory nerves in multiple sclerosis.
1978
Maximum conduction velocity and relative refractory period (RRP) of median nerve sensory fibers were studied in 36 patients diagnosed as having multiple sclerosis (MS) and in 31 controls. Maximum conduction velocity did not differ in the two groups, but the RRP was significantly prolonged in MS patients. Increased RRP is observed mainly when peripheral nerve myelin is abnormal or damaged. Our findings support the assumption that peripheral nerve myelinated fibers are usually involved in MS.
Inferior altitudinal hemianopia associated with a tumor in the posterior fossa: report of a case
1984
Altitudinal hemianopias may be related to chiasmatic involvement. A case in which horizontal inferior hemianopia is associated with a tumor in the posterior fossa producing a triventricular hydrocephalus is described. The visual field defect is interpreted as a consequence of the pressure by a dilated third ventricle upon the chiasmatic area.
Sympathetic Vasomotor Response of the Radial Artery in Patients With Diabetic Foot Syndrome
2003
OBJECTIVE—Neurophysiological assessment of the peripheral autonomic system is characterized by various limitations. An alternative approach to laser Doppler and venous plethymography is the assessment of the sympathetic vasomotor response of the radial artery obtained by continuous wave Doppler sonography. Nomogram data have been established and demonstrate the temporary disappearance of diastolic flow after coughing or deep inspiration. RESEARCH DESIGN AND METHODS—We assessed the sympathetic vasomotor response in 25 patients (mean age 64 years, range 43–76) with diabetic foot syndrome. The Doppler data were correlated with nerve conduction studies of the median and peroneal nerve, the exte…
Influence of nerve branch of origin and extracanalicular extension of the tumor on hearing after middle fossa removal of vestibular schwannoma
2007
Neither nerve branch of origin nor extracanalicular (up to 1 cm) extension of a vestibular schwannoma (VS) influence the postoperative hearing outcome in patients operated via a middle cranial fossa (MCF) approach.To test whether the nerve branch of tumor origin and an extracanalicular, up to 1 cm, tumor extension influences hearing outcome after MCF VS surgery.This was a retrospective case review of 50 patients with postoperative pure-tone audiogram (PTA) performed later than 90 days after surgery. Twenty patients had a superior vestibular nerve (SVN) tumor and 27 patients had an inferior vestibular nerve (IVN) tumor. In three patients the nerve branch of origin of the VS could not be uneq…
